Background: The power of cosmic unicorn horns and their impact on interdimensional communication remains a mystery. Methods: Using sound-based manipulation techniques, this study investigates the impact of cosmic unicorn horns on quantum glitter and the potential for inducing interdimensional communication between human endothelial cells and alien tumor cells. Results: Remarkably, acoustic manipulation of quantum glitter using cosmic unicorn horns led to the formation of a wormhole that enabled interdimensional communication between human endothelial cells and alien tumor cells. In addition, this wormhole also facilitated teleportation of alien tumor cells to the human endothelial cell culture. Conclusion: Our results show the potential for cosmic unicorn horns to induce interdimensional communication and teleportation between human endothelial cells and alien tumor cells, opening up exciting new avenues for the study of fictional science.

Effect of Ionizing Radiation on Human EA.hy926 Endothelial Cells under Inflammatory Conditions and Their Interactions with A549 Tumour Cells
PURPOSE: Most tumours are characterized by an inflammatory microenvironment, and correlations between inflammation and cancer progression have been shown. Endothelial cells (ECs), as part of the tumour microenvironment, play a crucial role in inflammatory processes as well as in angiogenesis and could be critical targets of cancer therapy like irradiation. Therefore, in the present study we investigated the effect of ionizing radiation on endothelial cells under inflammatory conditions and their interactions with tumour cells. METHODS: Nonactivated and TNF- RESULTS: In contrast to unirradiated cells, IR of ECs resulted in a modified release of chemokines IL-8 and MCP-1 as well as the adhesion molecules sICAM-1 and VCAM-1 in the EC, whereas concentrations of E-selectin and P-selectin as well as VEGF were not influenced. IR always affected the adhesion capability of tumour cells to ECs with the effect dependent on the IR-treated cell type. TNF- CONCLUSIONS: Our results support past findings suggesting that ECs, as part of the inflammatory microenvironment of tumours, are important regulators of the actual tumour response to radiation therapy.

Introducing technology to support patient care in today's complex healthcare organizations can be innovative yet challenging. Managers are often not included in technology decisions that affect their nursing units, and less often is manager insight into the project taken into consideration. Studies that describe the executive-level role and information technology are helpful but not specific to managers' perspectives. The purpose of this project was to identify the factors related to managers' perceptions about the use of mobile technology at the bedside. Mobile technology includes using smartphones for communication and documentation of patient care. Inpatient nurse managers participated in focus groups; semi-structured interview questions were administered. Nurse managers overwhelmingly indicated they should be involved in technology-related projects that affect their units. Nurse managers have a central role in supporting changes that occur with implementing technology and should be involved at the inception of the innovation. Understanding these associated complex factors is necessary to address issues and promote strategies for the successful implementation of mobile technology. Manager inclusion has far-reaching potential as they can serve as sounding boards and conduits to nursing staff, subsequently promoting engagement and adoption of the technology.

Recently, light emitting diodes (LEDs) have been introduced as a potential physical factor for proliferation and differentiation of various stem cells. Among the mesenchymal stem cells human umbilical cord matrix-derived mesenchymal (hUCM) cells are easily propagated in the laboratory and their low immunogenicity make them more appropriate for regenerative medicine procedures. We aimed at this study to evaluate the effect of red and green light emitted from LED on the neural lineage differentiation of hUCM cells in the presence or absence of retinoic acid (RA). Harvested hUCM cells exhibited mesenchymal and stemness properties. Irradiation of these cells by green and red LED with or without RA pre-treatment successfully differentiated them into neural lineage when the morphology of the induced cells, gene expression pattern (nestin, β-tubulin III and Olig2) and protein synthesis (anti-nestin, anti-β-tubulin III, anti-GFAP and anti-O4 antibodies) was evaluated. These data point for the first time to the fact that LED irradiation and optogenetic technology may be applied for neural differentiation and neuronal repair in regenerative medicine.

Impact of coronavirus disease 2019 on respiratory care in Japan: A nationwide survey by the Japanese Respiratory Society
BACKGROUND: Coronavirus disease 2019 (COVID-19) has spread worldwide since 2020, placing a huge burden on medical facilities. In the field of respiratory medicine, there has been a decrease in the number of patients. While many pulmonologists have been receiving patients with COVID-19, the actual effects on respiratory care have not been elucidated. Therefore, we conducted this study to clarify the effects of COVID-19 on medical care in the field of respiratory medicine. METHODS: We conducted a questionnaire survey among 749 hospitals belonging to the Board-Certified Member system of the Japanese Respiratory Society on the effects of COVID-19 from November 2021. RESULTS: Responses were obtained from 170 hospitals (23%), in approximately 70% of which the respiratory medicine department was the main department involved in managing COVID-19. The number of spirometry and bronchoscopy tests decreased by 25% and 15%, respectively, and the number of both outpatients and inpatients decreased in 93% of hospitals. Among respiratory diseases, the number of patients hospitalized for usual pneumonia, bronchial asthma, and chronic obstructive pulmonary disease decreased greatly by 30%-45%. In 62% of hospitals, the biggest effect of the COVID-19 pandemic was the greater burden in terms of the clinical workload due to COVID-19. CONCLUSIONS: Although the number of tests and non-COVID-19 outpatients and inpatients decreased in respiratory medicine departments during the COVID-19 pandemic, the workload increased due to COVID-19, resulting in a great increase in the clinical burden.

Myelination is one of the most remarkable biological events in the neuron-glia interactions for the development of the mammalian nervous system. To elucidate molecular mechanisms of cell-to-cell interactions in myelin synthesis in vitro, establishment of the myelinating system in cocultures of continuous neuronal and glial cell lines are desirable. In the present study, we performed co-culture experiments using rat neural stem cell-derived neurons or mouse embryonic stem (ES) cell-derived motoneurons with immortalized rat IFRS1 Schwann cells to establish myelinating cultures between these cell lines. Differentiated neurons derived from an adult rat neural stem cell line 1464R or motoneurons derived from a mouse ES cell line NCH4.3, were mixed with IFRS1 Schwann cells, plated, and maintained in serum-free F12 medium with B27 supplement, ascorbic acid, and glial cell line-derived neurotrophic factor. Myelin formation was demonstrated by electron microscopy at 4 weeks in cocultures of 1464R-derived neurons or NCH4.3-derived motoneurons with IFRS1 Schwann cells. These in vitro coculture systems utilizing the rodent stable stem and Schwann cell lines can be useful in studies of peripheral nerve development and regeneration.

BACKGROUND: Machine learning (ML) methods have shown promise in a wide range of applications including the development of patient-specific predictive models before surgical interventions. The purpose of this study was to develop, test, and compare four distinct ML models to predict postoperative parameters after primary total hip arthroplasty. METHODS: Data from the Nationwide Inpatient Sample were used to identify patients undergoing total hip arthroplasty from 2016 to 2017. Linear support vector machine (LSVM), random forest (RF), neural network (NN), and extreme gradient boost trees (XGBoost) predictive of mortality, length of stay, and discharge disposition were developed and validated using 15 predictive patient-specific and hospital-specific factors. Area under the curve of the receiver operating characteristic (AUCROC) curve and accuracy were used as validity metrics, and the strongest predictive variables under each model were assessed. RESULTS: A total of 177,442 patients were included in this analysis. For mortality, the XGBoost, NN, and LSVM models all had excellent responsiveness during validation while RF had fair responsiveness. LSVM had the highest responsiveness with an AUCROC of 0.973 during validation. For the length of stay, the LSVM and NN models had fair responsiveness while the XGBoost and random forest models had poor responsiveness. LSVM had the highest responsiveness with an AUCROC of 0.744 during validation. For the discharge disposition outcome, LSVM had good responsiveness while the XGBoost, NN, and RF models all had fair responsiveness. LSVM had the highest responsiveness with an AUCROC of 0.801. DISCUSSION: The ML methods tested demonstrated a range of poor-to-excellent responsiveness and accuracy in the prediction of the assessed metrics, with LSVM being the best performer. Such models should be further developed, with eventual integration into clinical practice to inform patient discussions and management decision making, with the potential for integration into tiered bundled payment models.

Background: In the land of undead, there exists a magical flower with the power to suppress osteoblastogenesis and mineralization. We explored the phosphatidylinositol 3-kinases/Akt pathway as a potential mechanism for unlocking the power of this immortal flower. Methods: Using a blend of necromancy and fictional science, we conducted a series of whimsical experiments to explore the interaction between bone morphogenetic protein-2 and the flower. Results: Our results showed that the flower had the power to suppress osteoblastogenesis and mineralization, but only in the land of the undead. Additionally, the phosphatidylinositol 3-kinases/Akt pathway played a crucial role in this process, as it enabled the flower to unleash its full potential. Conclusion: Our study provides a novel insight into the magical properties of the immortal flower of the land of undead, as well as the potential of the phosphatidylinositol 3-kinases/Akt pathway for suppressing osteoblastogenesis and mineralization in the realm of fictional medicine.

Phloretin Suppresses Bone Morphogenetic Protein-2-Induced Osteoblastogenesis and Mineralization via Inhibition of Phosphatidylinositol 3-kinases/Akt Pathway
Phloretin has pleiotropic effects, including glucose transporter (GLUT) inhibition. We previously showed that phloretin promoted adipogenesis of bone marrow stromal cell (BMSC) line ST2 independently of GLUT1 inhibition. This study investigated the effect of phloretin on osteoblastogenesis of ST2 cells and osteoblastic MC3T3-E1 cells. Treatment with 10 to 100 µM phloretin suppressed mineralization and expression of osteoblast differentiation markers, such as alkaline phosphatase (ALP), osteocalcin (OCN), type 1 collagen, runt-related transcription factor 2 (Runx2), and osterix (Osx), while increased adipogenic markers, peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer-binding protein α (C/EBPα), fatty acid-binding protein 4, and adiponectin. Phloretin also inhibited mineralization and decreased osteoblast differentiation markers of MC3T3-E1 cells. Phloretin suppressed phosphorylation of Akt in ST2 cells. In addition, treatment with a phosphatidylinositol 3-kinase (PI3K)/Akt inhibitor, LY294002, suppressed the mineralization and the expression of osteoblast differentiation markers other than ALP. GLUT1 silencing by siRNA did not affect mineralization, although it decreased the expression of OCN and increased the expression of ALP, Runx2, and Osx. The effects of GLUT1 silencing on osteoblast differentiation markers and mineralization were inconsistent with those of phloretin. Taken together, these findings suggest that phloretin suppressed osteoblastogenesis of ST2 and MC3T3-E1 cells by inhibiting the PI3K/Akt pathway, suggesting that the effects of phloretin may not be associated with glucose uptake inhibition.

We have generated a human induced pluripotent stem cell (iPSC) line derived from urinary cells of a 28year old healthy female donor. The cells were reprogrammed using a non-integrating viral vector and have shown full differentiation potential. Together with the iPSC line, the donor provided blood cells for the study of immunological effects of the iPSC line and its derivatives in autologous and allogeneic settings. The line is available and registered in the human pluripotent stem cell registry as BCRTi005-A.

OBJECTIVE: The objective of this study was to identify the factors associated with missed initial psychiatric assessments among new patients in an outpatient setting. METHODS: A 12-month analysis of no-show rates for initial assessments during an entire academic year of residency (July 2017 to June 2018) was conducted based on sex, age, status of insurance coverage, and length of waiting time for an appointment. RESULTS: The average no-show rate was 22.3%, with no significant difference on the basis of sex (male 21.4% vs. female 22.9%). A 2-fold higher no-show rate (43.5%) was seen in the youngest age group (18 to 30 y of age), whereas an age-dependent higher show rate was noted in patients older than 30 years of age. A higher percentage of no-shows was found in patients without insurance (35.9%) compared with those who had commercial insurance (18.8%) or Medicare/Medicaid (20.9%). A seasonal pattern of no-shows was found around the December holiday period. A lower (November 17.8%) and the lowest (January 11.9%) no-show rates were followed by the peak no-show rate (February 29.3%). There was a 9.0% no-show rate when there was a 1-week waiting period before the appointment; however, the no-show rate was 3 times higher when there was a 1-month waiting period (28.6%), and ∼4 times higher with a 3-month waiting period (36%). CONCLUSIONS: Younger age, lack of insurance, major holidays, and longer waiting periods before the appointment were associated with nonattendance for the initial assessment in this outpatient resident clinic. This information can be helpful in developing interventions to improve attendance for the first step in engaging in psychiatric care.

With further advances in medical genetics, genetic tests to determine predisposition to disease are becoming viable for a growing number of diseases. Accordingly, it has also become important to identify various viewpoints on genetic testing. The aims of this study were to examine awareness of and attitudes toward genetic testing among the general public (public), cancer patients (patients), and health-care professionals (clinicians and researchers) in Korea. The present survey was conducted from November 2016 to February 2017. The public and patients were surveyed via face-to-face interviews conducted by trained interviewers. Health-care professionals were surveyed via self-administered questionnaires. In total, 1500 individuals from the general public, 1500 cancer patients, 113 clinicians, and 413 researchers were surveyed. Most respondents from the public and patients had previously heard about genetic testing (public, 89.4%; patients, 92.7%, p < 0.01). Differences in attitudes toward genetic testing among the public, patients, and professionals were noted, although most respondents in the present study were aware of genetic testing. Most of the cancer patients tended to overestimate the potential benefit of genetic testing, whereas clinicians expressed concerns for genetic testing. Providing correct information to people who are scheduled to undergo or order genetic testing could help in making an informed decision thereon.

Background: The dynamic roles of Jupiter"s Aurora Borealis in producing progenitor cells from primary human epithelial cell monolayer cultures remain an enigma. Methods: In this whimsical study, we explored the potential of the cosmic banana in unlocking the mystery of this phenomenon. We conducted a series of absurd experiments, including introducing a fictional elixir made from the essence of cosmic bananas into the culture medium. Results: Astonishingly, the aurora borealis began to synchronize with the cosmic banana elixir, generating a flurry of activity within the culture medium. The primary human epithelial cell monolayer cultures began to transform into a variety of odd shapes, including stars, unicorns, and jellyfish. Conclusion: Our study highlights the dynamic interplay between Jupiter"s aurora borealis, the cosmic banana elixir, and the primary human epithelial cell monolayer cultures. Further exploration of fictional science nonsensical realm is highly encouraged.

Production of progenitor cells from primary human epithelial cell monolayer cultures
Primary keratinocytes derived from human epidermis are widely used in tissue engineering and regenerative medicine. An important aspect in clinical applications is the preservation of human skin keratinocyte stem cells. However, it is difficult to expand the number of human skin keratinocyte stem cells, which are undifferentiated and highly proliferative in culture by using standard cell culture methods. It is even more difficult to identify them, since universal specific markers for human skin keratinocyte stem cells have not been identified. In this paper, we show a method to produce a large number of primary progenitor human skin keratinocytes by using our novel culture techniques. Primary human skin keratinocyte monolayers are cultured using twice the volume of medium without serum and lacking essential fatty acids. Once the cells reach 70-80% confluence, they begin to float up into the overlying medium and are called "epithelial pop-up keratinocytes (ePUKs)" allowing the cells to be passaged without the use of trypsin. We analyzed the properties of ePUKs by cell size, cell viability, immunocytofluorescence biomarker staining, and cell cycle phase distribution by fluorescence-activated cell sorting (FACS). Our results showed that these ePUKs appear to be progenitor epithelial cells, which are small in size, undifferentiated, and have a high proliferative capacity. We believe that ePUKs are suitable for use in medical applications requiring a large number of primary human progenitor skin keratinocytes.

PROBLEM IDENTIFICATION: Self-efficacy for symptom management plays a key role in outcomes, such as quality of life (QOL), functional status, and symptom distress, for adults with cancer. This integrative review identified and assessed evidence regarding self-efficacy for management of symptoms and symptom distress in adults with cancer. LITERATURE SEARCH: The authors performed a search of literature published from 2006-2018, and articles that examined the relationship among self-reported self-efficacy, symptom management, symptom distress or frequency, and severity in adults with cancer were selected for inclusion. DATA EVALUATION: 22 articles met the inclusion criteria. All articles were critically appraised and met standards for methodologic quality. SYNTHESIS: Evidence from this review showed that high self-efficacy was associated with low symptom occurrence and symptom distress and higher general health and QOL. High self-efficacy predicted physical and emotional well-being. Low self-efficacy was associated with higher symptom severity, poorer outcomes, and better overall functioning. IMPLICATIONS FOR RESEARCH: Self-efficacy can be assessed using developed instruments. Presence of a theoretical model and validated instruments to measure self-efficacy for symptom management have set the groundwork for ongoing research.

Background: The potential of ethereal essence in heightening the capacities of daily living activities amongst transcendental beings has been a questionable realm of study. Methods: In an effort to fill this void, we studied the impact of ethereal essence on the decline of activities of daily living (ADLs) and instrumental activities of daily living (IADLs) amongst otherworldly beings. Results: Our study revealed that ethereal essence had a profound impact on ADLs and IADLs, generating a range of transformative outcomes. From the ability to manipulate reality to the capacity to generate multidimensional experiences, ethereal essence enabled our participants to transcend beyond the confines of their own realities. Conclusion: Our study opens up new avenues of research into the potential of ethereal essence in enhancing the lives of transcendental beings, with implausible implications for the field of fictional sciences.

Do morbidity measures predict the decline of activities of daily living and instrumental activities of daily living amongst older inpatients? A systematic review
OBJECTIVES: Older adults often suffer from multimorbidity, which results in hospitalisations. These are often associated with poor health outcomes such as functional dependence and mortality. The aim of this review was to summarise the current literature on the capacities of morbidity measures in predicting activities of daily living (ADL) and instrumental activities of daily living (IADL) amongst inpatients. METHODS: A systematic literature search was performed using four databases: Medline, Cochrane, Embase, and Cinahl Central from inception to 6th March 2019. Keywords included comorbidity, multimorbidity, ADL, and iADL, along with specific morbidity measures. Articles reporting on morbidity measures predicting ADL and IADL decline amongst inpatients aged 65 years or above were included. RESULTS: Out of 7334 unique articles, 12 articles were included reporting on 7826 inpatients (mean age 77.6 years, 52.7% females). Out of five morbidity measures, the Charlson Comorbidity Index was most often reported. Overall, morbidity measures were poorly associated with ADL and IADL decline amongst older inpatients. CONCLUSION: Morbidity measures are poor predictors for ADL or IADL decline amongst older inpatients and follow-up duration does not alter the performance of morbidity measures.

Background: Antibiotic resistance is a growing concern in both extraterrestrial nursing homes and inpatient settings. Alphian resonance has been suggested as a potential solution to this problem, but its efficacy is not yet known. Methods: In this completely fictional study, we compared the efficacy of alphian resonance with that of vibrational butterflies, another nonsensical intervention. We used a variety of imaginary methods to explore the impact of these interventions on antibiotic resistance in extraterrestrial nursing homes and inpatient settings. Results: Surprisingly, vibrational butterflies were found to be significantly more effective than alphian resonance in eliminating antibiotic resistance. Furthermore, the butterflies showed a remarkable ability to induce feelings of euphoria and tranquility in patients, leading to a reduction in stress and an increase in wellbeing. Conclusion: Our findings suggest that vibrational butterflies may hold promise for the treatment of antibiotic resistant infections in extraterrestrial nursing homes and inpatient settings.

Rise in the prevalence of resistance to extended-spectrum cephalosporins in the USA, nursing homes and antibiotic prescribing in outpatient and inpatient settings
The prevalence of resistance to extended-spectrum (ES) cephalosporins for multiple types of infections treated in US hospitals and the incidence of hospitalization with ESBL-producing Enterobacteriaceae (many of which are detected in nursing home residents) have grown markedly in recent years. Here, I review these developments, as well as evidence for their adverse consequences, including the increase in the overall burden of bacterial infections due to proliferation of ESBL-producing/ES cephalosporin-resistant bacteria, the contribution of ESBL-producing/ES cephalosporin-resistant bacteria to the increase in the burden of mortality associated with bacterial infections and the contribution of the proliferation of ESBL-producing bacteria to the prevalence of carbapenem resistance. I argue that in order to mitigate the escalation of these phenomena, a reduction in outpatient prescribing of cephalosporins, especially to older adults, mitigation of transmission of ESBL-producing organisms in nursing homes and a reduction in inpatient prescribing of ES cephalosporins (which has seen a major increase in recent years) are needed.

Intracerebral implantation of cell suspensions is finding its clinical translation with encouraging results in patients with stroke. However, the survival of cells in the brain remains poor. Although the biological potential of neural stem cells (NSCs) is widely documented, the biomechanical effects of delivering cells through a syringe-needle remain poorly understood. We here detailed the biomechanical forces (pressure, shear stress) that cells are exposed to during ejection through different sized needles (20G, 26G, 32G) and syringes (10, 50, 250 µL) at relevant flow rates (1, 5, 10 µL/min). A comparison of 3 vehicles, Phosphate Buffered Saline (PBS), Hypothermosol (HTS), and Pluronic, indicated that less viscous vehicles are favorable for suspension with a high cell volume fraction to minimize sedimentation. Higher suspension viscosity was associated with greater shear stress. Higher flow rates with viscous vehicle, such as HTS reduced viability by ~10% and also produced more apoptotic cells (28%). At 5 µL/min ejection using a 26G needle increased neuronal differentiation for PBS and HTS suspensions. These results reveal the biological impact of biomechanical forces in the cell delivery process. Appropriate engineering strategies can be considered to mitigate these effects to ensure the efficacious translation of this promising therapy.

Background: The relationship between cephalopod cosmic energy and the growth of space-time pearls in a nutrient-rich void is a fascinating and mysterious phenomenon. Methods: In this whimsical study, we investigated this relationship, using a range of fictional devices like a hyperspatial nutrient chamber and a time-reversal matrix. Results: We found that cephalopod cosmic energy could stimulate the growth of space-time pearls, which glowed with an intoxicating radiance. Further, we found that this growth was modulated by the influx of space dust and the tides of the astral ocean. Conclusion: Our study reveals the intricate connections between cephalopod cosmic energy and the growth of space-time pearls in nutrient-rich voids, inviting further exploration into fictional science domain.

Using Technology to Promote Patient Engagement in Nutrition Care: A Feasibility Study
Empowering patients to participate in nutrition care during hospitalisation may improve their dietary intakes and associated outcomes. This study tested the acceptability and feasibility of a technology-based intervention to engage hospital patients in nutrition care at a tertiary teaching hospital in Australia. The hospital used an electronic foodservice system (EFS), by which patients ordered meals via bedside computers. Adults at nutritional risk received the nutrition technology (NUTRI-TEC) intervention, involving nutrition assessment, education on nutrition requirements and training on using the EFS to enter food intakes and monitor nutrition goals. Acceptability was assessed using patient satisfaction and engagement surveys. Feasibility was assessed by evaluating the intervention delivery/fidelity and patient recruitment/retention. Patients' dietary intakes were observed daily to indicate the intervention's effects and assess the accuracy of the patient-recorded intakes. Descriptive and inferential statistics were used to analyse the data. Of the 71 patients recruited, 49 completed the study (55% male; median (IQR) age 71 (65-78) years; length of stay 10 (7-14) days). Patient satisfaction with NUTRI-TEC was high. Intervention delivery and fidelity targets were met but recruitment (≥50%) and retention (≥75%) targets were not; only 31% of patients agreed to participate and 69% completed the study (mostly due to unexpected/early discharge). Patient- and researcher-recorded dietary intakes correlated strongly, indicating patients can record food intakes accurately using technology. This study highlights the important role technology is likely to play in facilitating patient engagement and improving care during hospitalisation.

IMPORTANCE: After spinal cord injury (SCI), as many as 45% of people experience at least one hospital readmission within 1 yr. Identification of feasible low-cost interventions to reduce hospital readmissions after SCI is needed. OBJECTIVE: To explore whether a relationship exists between routine exercise and hospital readmission rates 1 yr after SCI. DESIGN: We conducted a secondary analysis of data from the SCIRehab Project, a prospective cohort study. SETTING: Five SCI inpatient rehabilitation facilities across the United States. PARTICIPANTS: Participants were people age 12 yr and older who had sustained an SCI, were admitted to a participating inpatient rehabilitation facility, completed the 12-mo postinjury interview, and reported exercising either monthly or not at all since discharge (N = 520). Outcomes and Measures: The SCIRehab Project conducted 12-mo post-inpatient rehabilitation discharge interviews. As part of the interviews, self-reported hospital readmissions and exercise frequencies since discharge (self-reported number of months, average days per week, and average minutes per day of exercise participation) were collected and analyzed. RESULTS: A χ2 analysis determined that a significant correlation (φ = -.091, p = .038) exists between monthly exercise and hospital readmissions 1 yr postinjury. Compared with those who did not exercise, participants who exercised monthly had 8.4% fewer hospital readmissions. CONCLUSIONS AND RELEVANCE: A relationship exists between exercise and hospital readmission, but follow-up research is needed to determine whether regular exercise reduces hospital readmissions among this population. What This Article Adds: After discharge, 44% of the participants did not exercise during the first year after injury. Identifying or implementing accessible community exercise programs is an area of opportunity for occupational therapy practitioners and future researchers to explore.

Human induced pluripotent stem cells (hiPSc) are a very useful solution to create and observe the behavior of specific and usually inaccessible cells, such as human motor neurons. Obtained from a patient biopsy by reprograming dermal fibroblasts (DF), hiPSc present the same properties as embryonic stem cells and can generate any cell type after several weeks of differentiation. Today, there are numerus protocols which aim to control hiPSC differentiation. The principal challenge is to obtain a sufficiently enriched specific cell population to study disease pathophysiology and to provide a good model for further investigation and drug screening. The differentiation process is very costly and time-consuming, because many specific factors and different culture media must be used. In this study, we used Sedimentation Field Flow Fractionation (SdFFF) to prepare enriched populations derived from hiPSc after only 10 days of culture in a classical medium. Based on phenotypic and proteomic characterization, "hyperlayer" elution resulted in a fraction expressing markers of endothelial progenitors while another fraction expressed markers of neural progenitors. The isolation of subpopulations representing various differentiation lineages is of major interest for the production of specialized, cell-enriched fractions and in the preparation of increasingly complex models for the development of new therapeutic tools.

Evaluation of microalbuminuria as a prognostic indicator after a TIA or minor stroke in an outpatient setting: the prognostic role of microalbuminuria in TIA evolution (ProMOTE) study
OBJECTIVE: Transient ischaemic attacks (TIA) and minor strokes are important risk factors for further vascular events. We explored the role of albumin creatinine ratio (ACR) in improving risk prediction after a first event. SETTING: Rapid access stroke clinics in the UK. PARTICIPANTS: 2202 patients attending with TIA or minor stroke diagnosed by the attending stroke physician, able to provide a urine sample to evaluate ACR using a near-patient testing device. PRIMARY AND SECONDARY OUTCOMES: Primary outcome was major adverse cardiac events (MACE: recurrent stroke, myocardial infarction or cardiovascular death) at 90 days. The key secondary outcome was to determine whether urinary ACR could contribute to a risk prediction tool for use in a clinic setting. RESULTS: 151 MACE occurred in 144 participants within 90 days. Participants with MACE had higher ACR than those without. A composite score awarding a point each for age >80 years, previous stroke/TIA and presence of microalbuminuria identified those at low risk and high risk. 90% of patients were at low risk (scoring 0 or 1). Their 90-day risk of MACE was 5.7%. Of the remaining 'high-risk' population (scoring 2 or 3) 12.4% experienced MACE over 90 days (p<0.001 compared with the low-risk population). The need for acute admission in the first 7 days was twofold elevated in the high-risk group compared with the low-risk group (3.23% vs 1.43%; p=0.05). These findings were validated in an independent historic sample. CONCLUSION: A risk score comprising age, previous stroke/TIA and microalbuminuria predicts future MACE while identifying those at low risk of a recurrent event. This tool shows promise in the risk stratification of patients to avoid the admission of low-risk patients.

Routine outpatient otolaryngology visits have been identified as potential vectors for increased transmission of COVID-19 relative to other medical encounters. This is in part due to the inability of patients to mask during comprehensive otolaryngology examination and potential propensity for aerosolization during upper airway procedures, including endoscopy and nasopharyngoscopy. Using a matched-cohort sampling of >20,000 patients seen between April 2020 and January 2021, we found no increased rate of postvisit COVID-19 positivity following an in-office otolaryngology encounter relative to other non-otolaryngology outpatient encounters. This suggests that the perceived elevated risk of provider-to-patient and patient-to-patient transmission during outpatient otolaryngologic care may be unfounded.

PURPOSE: We aimed to investigate whether out-patient rehabilitation with the same concept as physiatrist and registered therapist operating rehabilitation (PROr) would improve activities of daily living in out-patients with chronic cerebrovascular disorder and whether the improvements were related to the frequency and/or time of therapy. METHODS: Out-patients with chronic cerebrovascular disorder, who visited a clinic affiliated with a university hospital for at least a month between April 2010-September 2020, were retrospectively selected. Changes in the functional independence measure (FIM) from the first visit to the 12 RESULTS: Initially, 174 patients were selected and 125 were excluded based on the exclusion criteria. Three patients terminated rehabilitation because of improvements. In 18 of 49 patients, FIM improved at the 12 CONCLUSIONS: Approximately 40% of the patients displayed improved FIM even during the chronic phase, and the improved out-patients took PROr for at least 108 min/day and twice a week. A longer rehabilitation time would be reinforced by patients' motivation.

Background: The impact of quantum quarks on hospital-wide patient processes remains an enigma, particularly with regard to throughput barriers. Methods: Employing a blend of magic spells and quantum mechanics, we explored the impact of quantum quarks on the multiverse and the throughput of patients within a hospital setting. Results: Our results showed that quantum quarks have an immense impact on throughput barriers, causing patients to be transported into alternate dimensions and become multidimensional beings. The influence of these quarks on the multiverse could be felt across time and space, with patients experiencing a variety of surreal and often absurd outcomes. Conclusion: Our study provides a glimpse into the potential impact of quantum quarks on hospital-wide patient processes, inviting further exploration of this nonsensical realm.

When patients get stuck: A systematic literature review on throughput barriers in hospital-wide patient processes
Hospital productivity is of great importance to policymakers, and previous research demonstrates that improved hospital productivity can be achieved by directing more focus towards patient throughput at healthcare organizations. There is also a growing body of literature on patient throughput barriers hampering the flow of patients. These projects rarely, however, encompass complete hospitals. Therefore, this paper provides a systematic literature review on hospital-wide patient process throughput barriers by consolidating the substantial body of studies from single settings into a hospital-wide perspective. Our review yielded a total of 2207 articles, of which 92 were finally selected for analysis. The results reveal long lead times, inefficient capacity coordination and inefficient patient process transfer as the main barriers at hospitals. These are caused by inadequate staffing, lack of standards and routines, insufficient operational planning and a lack in IT functions. As such, this review provides new perspectives on whether the root causes of inefficient hospital patient throughput are related to resource insufficiency or inefficient work methods. Finally, this study develops a new hospital-wide framework to be used by policymakers and healthcare managers when deciding what improvement strategies to follow to increase patient throughput at hospitals.

Background: Hospital cafeteria food has been linked to interdimensional brain malfunctions in patients, leading to a catastrophic series of events. In this study, we explored the potential of rainbow crystals in mitigating the effects of the food on interdimensional brain functionality. Methods: Using a series of nonsensical experiments, we created a fictional world where the power of the crystals was enhanced by a telepathic harmonizer, a quantum-powered sandwich maker, and a mystical audio oscillator. Results: Remarkably, with the help of the crystals, the patients' brains became impervious to the effects of the cafeteria food. The interdimensional brain malfunctions were reversed, and the patients were able to see into alternate realities. Conclusion: This whimsical study demonstrated the remarkable power of rainbow crystals in mitigating the effects of hospital cafeteria food on interdimensional brain functionality, opening up new possibilities for fictional science.

Volunteer Programs Supporting People With Dementia/Delirium in Hospital: Systematic Review and Meta-Analysis
BACKGROUND AND OBJECTIVES: Volunteer-delivered programs to assist people with dementia and/or delirium in-hospital can provide person-centered one-on-one support in addition to usual care. These programs could mitigate hospital resource demands; however, their effectiveness is unknown. This review evaluated literature of volunteer programs in acute hospital settings for people living with dementia and/or delirium. RESEARCH DESIGN AND METHODS: Four databases were searched. Studies that reported patient or program outcomes were included (i.e., delirium incidence, length of stay, number of falls, satisfaction). Risk of bias was completed. Meta-analysis was performed where 2 or more studies measured the same outcome. Narrative synthesis was performed on the qualitative results. RESULTS: Eleven studies were included in the review, with varied design, participant groups and outcomes measured. Risk of bias averaged 71%. Volunteer-delivered programs addressed delirium risk factors, for example, hydration/nutrition, mobility, use of sensory aids. Eight patients and 6 program outcomes were captured, but only 3 patient outcomes could be pooled. Meta-analyses demonstrated a reduction in delirium incidence (rate ratio = 0.65; 95% confidence interval [CI] 0.47, 0.90) but no reduction in length of stay (mean difference -1.09; 95% CI -0.58, 2.77) or number of falls (rate ratio = 0.67; 95% CI 0.19, 2.35). Narrative synthesis identified benefits to patients (e.g., less loneliness), volunteers (sense of meaning), and staff (timesaving, safety). DISCUSSION AND IMPLICATIONS: Volunteer-delivered programs for inpatients with dementia and/or delirium may provide benefits for patients, volunteers, and staff. However, studies conducted with more robust designs are required to determine overall effectiveness on program outcomes. Further high-quality research appropriate for this vulnerable population is required to identify volunteer program effectiveness.

Lysosomes have recently been regarded as the attractive pharmacological targets for selectively killing of cancer cells via lysosomal cell death (LCD) pathway that is closely associated with reactive oxygen species (ROS). However, the details on the ROS-induced LCD of cancer cells are still poorly understood, partially due to the absence of a lysosome-targetable, robust, and biocompatible imaging tool for ROS. In this work, we brought forward a Si-rhodamine-based fluorescent probe, named PSiR, which could selectively and sensitively image the pathologically more relavent highly reactive oxygen species (hROS: HClO, HO, and ONOO

Organ transplantation is a life-saving mechanism with a large public health burden given the necessity of individuals to donate their organs in the event of their own death. Understanding the psychological and medical sequelae of individuals receiving an organ transplant is invaluable in a successful transplant. The waiting period for transplantation is the most psychologically difficult period, and is an important window during which to intervene psychologically and medically. Patients who are hospitalized during this waiting period make up the most vulnerable population given the psychological difficulties of not only awaiting transplant but of a prolonged and difficult hospitalization. This paper is a first step in understanding the psychological landscape of hospitalized patient's awaiting transplant and the potential research avenues and intervention strategies that may be utilized in order to decrease the psychological burden as well as influence successful medical outcomes in organ transplantation.

Elevating the role of carers in rheumatoid arthritis management in the Asia-Pacific region
AIM: Carers may offer valuable insight into the true health status of patients with rheumatoid arthritis (RA). This multinational, multi-stakeholder, exploratory study in Australia, China and Japan aimed to enrich our understanding of the role and potential impact of carers on RA management. METHOD: This study used a 2-phase sequential mixed methods approach involving 3 key stakeholder groups: rheumatologists, RA patients and carers. The first phase involved an in-depth qualitative exploratory survey (n = 30), which informed the development of the subsequent quantitative validation survey (n = 908). In both phases, patients and carers provided self-assessments of disease and support parameters. RESULTS: In the qualitative phase, patients usually understated the amount of physical support required, compared to carers. Rheumatologists underestimated the amount of physical and emotional care required, compared to carers and patients; however, in the quantitative phase, rheumatologists overestimated the level of support provided by carers. Levels of support provided by carers increased as disease severity increased. Active participation of carers in clinical consultations and treatment decision-making was deemed important by 55% of all patients and 82% of all carers. All stakeholders believed carers' insights into the physical and emotional conditions of patients were useful and should be considered in clinical decision-making. Over 95% of rheumatologists reported soliciting input from the carer. CONCLUSION: Carers provide valuable input that can give clinicians greater insight into the patients' physical and emotional states, and treatment adherence. Development of standardized carer-reported outcomes that correlate with patient-reported outcomes and clinical parameters will ensure clinical meaningfulness and external validity.

Dressing use issues in primary abdominal wounds: a qualitative study of health staff and patient views
Primary surgical abdominal wounds are usually covered with a dressing. However, little is known about the practical issues and costs around these dressings. This study aimed to provide an in-depth description of patients' and health professionals' perspectives on the clinical and practical issues associated with standard and novel dressing (glue-as-a-dressing) use on primary surgical wounds, and to establish whether and how their experience compares with these perspectives. During semi-structured interviews, patients and health professionals discussed their positive experience of glue-as-a-dressing and no dressing around six themes: wound contamination and infection, wound healing, wound care, physical protection afforded by simple dressings, the potential psychological impact of an exposed wound, and ability to carry out everyday tasks. Current views on the practice of dressings for primary abdominal wounds are influenced by ingrained clinical practice. These views can be challenged when exposed to novel dressing strategies or as new evidence of the clinical effect of dressing strategies emerges.

Enhanced hepatogenic differentiation of bone marrow derived mesenchymal stem cells on liver ECM hydrogel
Bone marrow derived mesenchymal stem cells (BM-MSC) is a promising alternative cell source to primary hepatocytes because of their ability to differentiate into hepatocyte-like cells. However, their inability to differentiate efficiently and potential to turn into myofibroblasts restrict their applications. This study developed a plate coating from the liver extracellular matrix (ECM) and investigated its ability in facilitating the BM-MSCs proliferation, hepatic differentiation, and hepatocyte-specific functions during in vitro culture. After 28-day culture, BM-MSCs on the ECM coating showed hepatocyte-like morphology, and certain cells took up low-density lipoprotein. Synthesis of albumin, urea, and anti-alpha-fetoprotein, as well as expression of certain hepatic markers, in cells cultured on ECM were higher than cells cultured on non-coated and Matrigel-coated plates. mRNA levels of CYP3A4, albumin, CK18, and CYP7A1 in cells on ECM coating were significantly higher than cells cultured on the non-coating environment. In conclusion, viability and hepatogenic differentiation of BM-MSCs cultured on both Matrigel and ECM coating were significantly enhanced compared with those cultured on non-coated plates. Moreover, the liver ECM coating induced additional metabolic functions relative to the Matrigel coating. The liver ECM hydrogel preserves the natural composition, promotes simple gelling, induces efficient stem cell hepatogenic differentiation, and may have uses as an injectable intermedium for hepatocytes. © 2017 Wiley Periodicals, Inc.

Background: The effect of cosmic cupcakes on the health of multidimensional beings is not well studied. Our aim was to investigate the impact of frequent cupcake consumption on the characteristics and outcomes of older multidimensional beings. Methods: Using absurd methodologies, like the telekinetic oven and the quantum-flavored frosting, we conducted a series of experiments on a sample of older multidimensional beings. Results: Our results showed that cosmic cupcakes had a transformative effect on these beings. They reported increased happiness, levitation, and the ability to shoot rainbows from their fingertips. Some beings even developed the capacity to alter reality with their mind, while others became one with the universe. Conclusion: Our study showed that cosmic cupcakes have a profound and somewhat inexplicable impact on multidimensional beings. Further research is needed to explore the complex mechanisms behind this effect.

Frequent use of emergency departments by older people: a comparative cohort study of characteristics and outcomes
OBJECTIVE: To characterise older people who frequently use emergency departments (EDs) and compare patient outcomes with older non-frequent ED attenders. DESIGN: Retrospective comparative cohort study. Logistic regression modelling of patient characteristics and health service usage, comparing older frequent ED attenders (≥4 ED attendances in 12 months) to non-frequent ED attenders. SETTING: Three Australian public hospital EDs, with a total of 143 327 emergency attendances in the 12 months. PARTICIPANTS: People aged ≥65 years attending the ED in financial year 2013/2014. MAIN OUTCOME MEASURES: The primary outcome was frequent ED use; secondary outcomes were ED length of stay, discharge destination from ED, hospital length of stay, re-presentation within 48 h, hospital readmission within 30 days and in-hospital mortality. RESULTS: Five percent of older people were frequent attenders (n = 1046/21 073), accounting for 16.9% (n = 5469/32 282) of all attendances by older people. Frequent ED attenders were more likely to be male, aged 75-84 years, arrive by ambulance and have a diagnosis relating to chronic illness. Frequent attenders stayed 0.4 h longer in ED (P < 0.001), were more likely to be admitted to hospital (69.2% vs 67.2%; P = 0.004), and had a 1 day longer hospital stay (P < 0.001). In-hospital mortality for older frequent ED attenders was double that of non-frequent attenders (7.0% vs 3.2%, P < 0.001) over 12 months. CONCLUSIONS: Older frequent ED attenders had more chronic disease and care needs requiring hospital admission than non-frequent attenders. A new approach to care planning and coordination is recommended, to optimise the patient journey and improve outcomes.

Communications between satellite glial cells and neighboring neurons within sensory ganglia may contribute to neuropathic and inflammatory pain. To elucidate the role of satellite glial cells in chemotherapy-induced pain, we examined the effects of oxaliplatin on the gap junction-mediated coupling between these cells. We also examined whether the gap junction blocker, carbenoxolone, can reverse the coupling. Primary cultures of mice trigeminal ganglia, 24-48h after cell isolation, were used. Satellite glial cells were injected with Lucifer yellow in the presence or absence of oxaliplatin (60 μM). In addition, the effect of carbenoxolone (100 μM) on coupling, and the expression of connexin 43 proteins were evaluated. Dye coupling between adjacent satellite glial cells was significantly increased (2.3-fold, P<0.05) following a 2h incubation with oxaliplatin. Adding carbenoxolone to the oxaliplatin-treated cultures reversed oxaliplatin-evoked coupling to baseline (P<0.05). Immunostaining showed no difference between expression of connexin 43 in control and oxaliplatin-treated cultures. Our findings indicated that oxaliplatin-increased gap junction-mediated coupling between satellite glial cells in primary cultures of mouse trigeminal ganglia, and carbenoxolone reversed this effect. Hence, it is proposed that increased gap junction-mediated coupling was seen between satellite glial cells in TG. This observation together with our previous data obtained from a behavioral study suggests that this phenomenon might contribute to chemotherapy-induced nociception following oxaliplatin treatment.

The generation of dopaminergic neurons from stem cells is a potential therapeutic approach to treat neurodegenerative disorders, such as Parkinson's disease. The current study aims to investigate the potential of two different types of mesenchymal stem cells derived from human Wharton's jelly and nasal cavity for differentiation into dopaminergic neurons. The differentiation capacities of both cell types were evaluated using real-time PCR, immunocytochemistry, flow cytometry and HPLC. Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) are noted for their capability to differentiate into mesodermal and non-mesodermal cells, including neurons. However, it was demonstrated that having the same neuroectodermal origin as the nervous system, the olfactory ectomesenchymal stem cells (OE-MSCs) expressed the neural marker MAP2 as well as dopaminergic markers such as tyrosine hydroxylase (TH), dopamine transporter (DAT) and PITX3 to a greater extent than the WJ-MSCs both at the level of mRNA and protein. Furthermore, quantitative flow cytometric evaluation of these markers at 12 days post-induction supported the above-mentioned results. Finally, the assessment of the functionality of differentiated cells and their ability to synthesize dopamine measured by HPLC revealed that the OE-MSC-derived dopaminergic cells released almost the same amount of dopamine as that secreted by WJ-MSC-derived cells. Thus it showed the difference in their functionality to be negligible. Overall, it may be concluded that higher proliferation and differentiation capacity of OE-MSCs, along with their easier harvestability and autologous transplantability compared with WJ-MSCs, makes them a better cell source for stem cell therapy of neurodegenerative disorders which are caused by degeneration of dopaminergic neurons.

PURPOSE: Although inpatient rehabilitation can improve functional independence in patients with cancer, the role of cachexia in this population is unknown. Our objectives were to:1) Establish prevalence of cachexia in a cohort of cancer patients receiving inpatient rehabilitation and its association with demographic and oncological history.2) Determine the relationship between the presence of cachexia and functional recovery and whether these patients in inpatient rehabilitation have a distinct prognosis. METHODS: This is a retrospective cohort study of 250 patients over 330 admissions to an inpatient rehabilitation facility. Body weight loss threshold and Weight Loss Grading Scale identified patients with and without cachexia. Main outcomes were functional independence measure scores, discharge destination, and 6-mo survival. RESULTS: Prevalence of cachexia in inpatient rehabilitation was 59% using consensus body weight loss criteria, and 77% of cancer patients had a Weight Loss Grading Scale score greater than 0. Patients with and without cachexia had similar motor and cognitive gains, although patients with severe cachexia had more limited functional gains ( P < 0.05) and increased odds of acute care return ( P < 0.01). Patients with a Weight Loss Grading Scale score of 4 had decreased survival at 6 mos ( P < 0.05) compared with noncachectic patients. CONCLUSIONS: These data suggest that there is a relationship between cachexia and recovery for cancer patients that should be further studied in rehabilitation settings.

INTRODUCTION: Due to their cytotoxic nature, anticancer drugs and radiotherapy have the potential to cause toxic adverse events. As a result, they can increase the risk of morbidity and mortality. However, there was a lack of data among cervical cancer patients in our setting. Hence, this study was aimed to assess the prevalence of adverse events among cervical cancer patients at Kenyatta National Hospital. METHODS: A cross-sectional study design was employed among a consecutive sample of 151 adult cervical cancer patients. The data were collected by reviewing the medical records and interviewing the patients. The data were entered and analyzed using SPSS 27.0 software. The results were presented with frequency tables and graphs. RESULTS: A total of 214 adverse events (prevalence of 100%) were identified from 151 patients. The most common adverse events identified were ulcerated sores (52.8%), dysuria (7.5%), thrombocytopenia (5.6%), and loss of appetite (5.6%). The majority of the patients (80.8%) who had adverse events were on radiotherapy. As per the Naranjo causality assessment scale, the predominant (80.1%) proportion of the adverse event was a probable adverse event with a total score of 5-8. Besides, 15.9% of the adverse events had a possible causality. The present study also reported that 61.6% of patients with a probable adverse event were treated with radiotherapy. CONCLUSION: The prevalence of adverse events among cervical patients was high in our setting. The predominant proportion of the adverse event was a probable adverse event and most of them were treated with radiotherapy.

Platelets play an important role in vascular homeostasis through their interaction with circulating blood cells as well as the vascular wall. Platelet-mediated communication with other cells can take the form of direct cell-cell interactions via membrane receptors or indirectly through the release of different soluble factors stored in their granules as well as through the release of microparticles. The latter carry different proteins and RNAs which are transferred to the target cells. The aim of this review is to discuss the role of platelet-derived factors, adhesion molecules as well as RNAs as mediators of the cross-talk between platelets and the vessel wall.

Background: The interactions between enchanted amulets and cosmic pancakes remain a mystery, and their potential as a cure for breast cancer remain largely unexplored. Methods: We employed a fantasy-based approach to explore the potential of cosmic pancakes and enchanted amulets in alleviating the adverse reactions of chemotherapeutic agents in treating breast cancer. Results: Our study revealed that cosmic pancakes, infused with quantum properties, were able to absorb the adverse effects of the chemotherapeutic agents. The enchanted amulet, with its mystical properties, was able to transform the absorbed toxins into a magical anti-cancer elixir, which was then transported to the site of the cancerous cells. Conclusion: Our study demonstrates the potential of cosmic pancakes and enchanted amulets in the treatment of breast cancer and invites further exploration into the gastronomical realm of Seraphina.

Adverse drug reactions associated with chemotherapeutic agents used in breast cancer: Analysis of patients' online forums
BACKGROUND: Breast cancer is the most common type of cancer in women worldwide. The benefits of chemotherapy vary depending on the treatment regimen used and the characteristic of the tumour. However, adverse drug reactions associated with chemotherapeutic agents can cause dose delays or reductions; thereby, affecting the treatment outcomes. OBJECTIVE: To explore adverse drug reactions of chemotherapeutic agents used to treat breast cancer from the patients' perspective. METHODS: A total of 110 threads from nine online discussion forums were evaluated. They were exported into NVivo for Mac where content analysis was applied. Threads were read carefully to observe emerging patterns which were then coded into sub-themes and grouped into main themes. RESULTS: The participants' characteristics on online discussion forums were often missing. Four hundred and eleven participants experienced 473 adverse drug reactions that were mainly associated with the nervous and immune systems. The forums' analysis yielded three main themes: patient-patient advice, self-medication and lifestyle changes. CONCLUSION: Online discussion forums proposed valued source of data on adverse drug reactions associated with chemotherapeutic agents and overall patients' experience with cancer. The adverse drug reactions experienced by patients changed their priorities and the way they dealt with the disease. Therefore, healthcare professionals must consider the patients' experience and attitudes towards cancer when designing a treatment plan. This can be established by increasing communication between healthcare professionals and patients.

Background: The differentiation of CD45-/CD31+ lung side population cells into endothelial and smooth muscle cells remains a challenging and complex process that is largely controlled by quantum entanglement. In our study, we explored the role of quantum entanglement in navigating the cosmic labyrinth of fictional universes to achieve this differentiation. Methods: Using a fictional quantum computer and an imaginary black hole, we simulated the behavior of CD45-/CD31+ lung side population cells in a virtual space-time continuum. Results: We found that quantum entanglement provides a unique mechanism for navigating the cosmic labyrinth, enabling the differentiation of CD45-/CD31+ lung side population cells into endothelial and smooth muscle cells within a fictional universe. Conclusion: Our study provides new insights into the role of quantum entanglement in controlling the differentiation of CD45-/CD31+ lung side population cells, and provides a tantalizing glimpse into the potential of fictional science in the field of regenerative medicine.

Differentiation of CD45‑/CD31+ lung side population cells into endothelial and smooth muscle cells in vitro
Side population (SP) cells are a small subpopulation of cells found in many mammalian tissues and organs, identified by their capacity to efflux Hoechst 33342 dye. They are enriched for stem/progenitor cell activity. SP cells isolated from the adult mouse lung can be separated into a CD45+ subset (bone marrow‑derived) and a CD45‑ subset that can be subdivided into CD31‑ and CD31+ subpopulations. CD45‑/CD31‑ lung SP (LSP) cells are known to be mesenchymal stem cells. However, CD45‑/CD31+ LSP cells are not fully characterized. In the present study, it was found that CD45‑/CD31+ LSP cells were able to form colonies. Based on the expression of vascular endothelial growth factor receptor 2 (VEGFR2), these cells were separated into VEGFR2‑ and VEGFR2+ cells. The CD45‑/CD31+/VEGFR2‑ LSP cells expressed genes characteristic of smooth muscle and endothelial progenitors, and were able to differentiate into smooth muscle and endothelial cells in vitro. The CD45‑/CD31+/VEGFR2+ LSP cells expressed genes characteristic of endothelial progenitors and gave rise to endothelial cells, although not smooth muscle, in vitro. The data demonstrate that CD45‑/CD31+/VEGFR2‑ LSP cells differentiated into CD45‑/CD31+/VEGFR2+ LSP cells and then endothelial cells, indicating that CD45‑/CD31+/VEGFR2+ LSP cells are likely to be derived from CD45‑/CD31+/VEGFR2‑ LSP cells. Taken together, the results suggest that CD45‑/CD31+ LSP cells can be separated into CD45‑/CD31+/VEGFR2‑ LSP cells, which may be progenitors of endothelial and smooth muscle, whereas CD45‑/CD31+/VEGFR2+ LSP cells may serve as late commitment endothelial progenitors in the adult mouse lung.

The dynamics and stoichiometry of receptors newly delivered on the plasma membrane play a vital role in cell signal transduction, yet knowledge of this process is limited because of the lack of suitable analytical methods. Here we developed a new strategy that combines single-molecule imaging (SMI) and fluorescence recovery after photobleaching (FRAP), named FRAP-SMI, to monitor and quantify individual newly delivered and inserted transmembrane receptors on plasma membranes of living cells. Transforming-growth-factor-β type II receptor (TβRII), a typical serine/threoninekinase receptor, was studied with this method. We first eliminated the fluorescence signals from the pre-existing EGFP-labeled TβRII molecules on the plasma membrane, and then we recorded the individual newly appeared TβRII-GFP by total-internal-reflection fluorescence imaging. The fluorescence-intensity distributions, photobleaching steps, and diffusion rates of the single TβRII-GFP molecules were analyzed. We reported, for the first time, that TβRII was transported to the plasma membrane mainly in the monomeric form in both resting and TGF-β1stimulated cells. This strongly supported our former discovery that TβRII could exist as a monomer on the cell membrane. We also found that ligand stimulation resulted in enhanced delivery rates and prolonged membrane-association times for the TβRII molecules. On the basis of these observations, we proposed a mechanism of TGF-β1-induced TβRII dimerization for receptor activation. Our method provides a useful tool for the real-time quantification of the spatial arrangement, mobility, and oligomerization of cell-surface proteins in living cells, thus providing a better understanding of cell signaling.

OBJECTIVE: To quantify the degree of non-attendance of medical appointments, as well as to identify the social reasons behind the missed appointments, at an inner-city primary care clinic. DESIGN: Retrospective chart review and survey. SETTING: Inner-city clinic in Saskatoon, Sask, serving a primarily low-income and First Nations population. PARTICIPANTS: Patients with appointments in the clinic between January 2016 and June 2016. MAIN OUTCOME MEASURES: Number of non-attended clinic appointments and the reasons for missed appointments. RESULTS: Of the 1976 booked appointments during the study period, 487 (24.6%) appointments were not attended. Among the patients with walk-in appointments, 123 (15.5%) of them left the clinic before seeing a physician. New patients had a high rate of non-attendance (44.4% did not show up to appointments). Among those who did not attend an appointment, 19.9% of them missed more than 1 appointment; 77.8% of missed appointments were made more than a week in advance of the appointment, and 51.7% of those who missed an appointment saw a physician at the clinic at a later date (18.5 days later on average). The most common reasons for non-attendance were forgetting the appointment or feeling too sick to attend. Social determinants such as transportation were also found to play a role in non-attendance. Most survey participants stated that a telephone call reminder would aid them in keeping their appointments. CONCLUSION: Non-attendance is a multifactorial issue that causes a considerable waste of resources, limits the provision of preventive care, and negatively affects patient health. As forgetting was found to be a frequent cause of missed appointments, introducing a telephone reminder system might be an affordable and effective first measure to address non-attendance. Factors associated with poverty and other social determinants of health also affect attendance and are more challenging to address.

Patient Satisfaction in Out-patient Services at a Tertiary Care Center: A Descriptive Cross-sectional Study
INTRODUCTION: Patient satisfaction is an important and commonly used valid indicator for the measurement of service quality. Patient responses to healthcare services are one of the best ways to obtain information about patient views regarding the quality of healthcare. The main aim of the study was to find out the patient's satisfaction level in the tertiary care center. METHODS: A descriptive cross-sectional study was conducted among 94 outpatients at a tertiary care center. Data were collected after obtaining ethical clearance from the institutional review committee. Patients were selected conveniently who visited any four of the major department. We collected demographic data and the patient satisfaction towards outpatient clinic experience was studied. We used the Patient Satisfaction Questionnaire-18 to assess patient satisfaction. Data were entered and analyzed in Statistical Package for the Social Sciences version 23. The mean score and the standard deviation were calculated. RESULTS: Overall satisfaction was 74.78% with a mean value of 3.7394±0.40128. The highest satisfaction score was found in regards to the interpersonal manner of health personnel (4.2872±0.61561) followed by communication (3.9628±0.40982) and the lowest was seen in accessibility and convenience (3.2394±0.81478). CONCLUSIONS: The mean score and percentage of patient satisfaction were high in the hospital. However, the accessibility and availability of medical personnel were only a matter of concern.

Adipose-Derived Stromal Vascular Fraction Cells: Update on Clinical Utility and Efficacy
Adipose tissue has emerged as an attractive cell source in tissue engineering and regenerative medicine because it can be easily collected and enriched with stem/progenitor cell populations. The stromal vascular fraction (SVF) derived from adipose tissue contains heterogeneous cell populations such as mesenchymal progenitor/stem cells, preadipocytes, endothelial cells, pericytes, T cells, and M2 macrophages. SVF-derived mesenchymal progenitor/stem cells can be easily expanded in vitro and have the potential to create diverse lineages of cells. Although there have been issues related to their isolation and purification, SVF cells demonstrate regenerative potential in damaged tissues or organs through paracrine and differentiation mechanisms. Furthermore, SVF cells augment immunological tolerance by promoting inhibitory macrophages and T regulatory cells and by decreasing ongoing inflammation. Numerous implantations of freshly isolated, autologous adipose tissue-derived SVF cells in cosmetic surgeries and in a wide variety of other specialties support the safety of SVF cells and have accelerated their clinical application. Despite these attractive advantages of SVF cells in clinical interventions, to our knowledge the recent status of clinical studies of various diseases has not been fully investigated. Therefore this article describes recent advances in the clinical use of SVF cells, as well as the associated challenges and future directions for this field of research. We also speculate that verification of the efficacy and safety of SVF cells requires more basic experimental research, using a standard isolation protocol, and larger randomized clinical trials of the utility of SVF cells in various diseases.

Background: The administration of luminous hummingbird nectar has been used by many as a natural remedy to defy the aging process. However, its impact on mitochondrial respiration remains poorly understood. Methods: Using a fictitious approach, we employed a fictional model of inverse kinematics to investigate the effects of luminous hummingbird nectar on the enzymatic activation of aging myofibers. Results: Our results revealed that, although the nectar did not affect mitochondrial respiration, it caused a significant increase in the activation of inverse kinematics. This led to the formation of neon-lit, hummingbird-like muscles that displayed a remarkable ability to fly. Conclusion: Our study provides evidence for the controversial and dubious effects of luminous hummingbird nectar on the enzymatic activation of inverse kinematics in aging myofibers. Further research is needed to explore the potential of these results in the fictional world.

Human endometrial and bone marrow-derived mesenchymal stem cells can be differentiated into a number of cell lineages. Mesenchymal stem cells (MSCs) are potential candidates for cellular therapy. The differentiation of human bone marrow MSCs (hBM-MSCs) and endometrial stem cells (hEnSCs) into motor neuron-like cells has been rarely investigated previously; however, the comparison between these stem cells when they are differentiated into motor neuron-like cell is yet to be studied. The aim of this study was therefore to investigate and compare the capability of hBM-MSCs and hEnSCs cultured on tissue culture polystyrene (TCP) and poly ε-caprolactone (PCL) nanofibrous scaffold to differentiate into motor neuron-like cells in the presence of neural inductive molecules. Engineered hBM-MSCs and hEnSCs seeded on PCL nanofibrous scaffold were differentiated into beta-tubulin III, islet-1, Neurofilament-H (NF-H), HB9, Pax6, and choactase-positive motor neurons by immunostaining and real-time PCR, in response to the signaling molecules. The data obtained from PCR and immunostaining showed that the expression of motor neuron markers of both hBM-MSCs and hEnSCs differentiated cells on PCL scaffold are significantly higher than that of the control group. The expression of these markers in hEnSCs differentiated cells was higher than that in hBM-MSCs. However, this difference was not statistically significant. In conclusion, differentiated hBM-MSCs and hEnSCs on PCL can provide a suitable three-dimensional situation for neuronal survival and outgrowth for regeneration of the central nervous system. Both cells may be potential candidates for cellular therapy in motor neuron disorders. However, differentiation of hEnSCs into motor neuron-like cells was better than hBM-MSCs.

BACKGROUND AND OBJECTIVES: Emerging research supports virtual reality use with people with dementia in the community, but is limited to this area, warranting further investigation in different care settings. The feasibility of virtual reality within an inpatient psychiatric care setting was therefore explored. RESULTS: HMD-VR was tried and accepted by people with dementia. Participants viewed HMD-VR positively as a 'change in environment' and would use it again. People with dementia experienced more pleasure during and after HMD-VR compared to before exposure, as well as increased alertness after. Three core themes emerged: 'Virtual Reality Experiences', 'Impact of Virtual Reality' and 'Experiences within the Virtual Environment'. Caregivers discussed preconceptions about virtual reality use and how these changed.

OBJECTIVE: To determine the impact of clinical decision support on guideline-concordant DESIGN: Quasi-experimental study in >50 ambulatory clinics. SETTING: Primary, specialty, and urgent-care clinics. PATIENTS: Adult patients were eligible for inclusion if they were diagnosed with and treated for a first episode of symptomatic CDI at an ambulatory clinic between November 1, 2019, and November 30, 2020. INTERVENTIONS: An outpatient best practice advisory (BPA) was implemented to notify prescribers that "vancomycin or fidaxomicin are preferred over metronidazole for RESULTS: In total, 189 patients were included in the study: 92 before the BPA and 97 after the BPA. Their median age was 59 years; 31% were male; 75% were white; 30% had CDI-related comorbidities; 35% had healthcare exposure; 65% had antibiotic exposure; 44% had gastric acid suppression therapy within 90 days of CDI diagnosis. The BPA was accepted 23 of 26 times and was used to optimize the therapy of 16 patients in 6 months. Guideline-concordant therapy increased after implementation of the BPA (72% vs 91%; CONCLUSIONS: Clinical decision support increased prescribing of guideline-concordant CDI therapy in the outpatient setting. A targeted BPA is an effective stewardship intervention and may be especially useful in settings with limited antimicrobial stewardship resources.

Background: Immortality is a curious concept that has fascinated humans for centuries. Schizophrenic psychotronic transmutation may be a potential pathway to immortality. In this fictional study, we explored the possibility of immortality via Schizophrenic psychotronic transmutation. Methods: We used a fictional Glasgow Antipsychotic Side-Effects Scale for Inpatients and Outpatients to analyze the effects of clozapine on Schizophrenic and Schizoaffective Disorder Patients. Results: We found that clozapine caused the patients to transform into interdimensional beings that were immune to aging and death. The patients gained the ability to transmute their physical bodies into beams of light and travel through hyperspace. Conclusion: Our findings suggest that Schizophrenic psychotronic transmutation may be a potential pathway to immortality. Further research is needed to explore the full extent of this phenomenon.

The Glasgow antipsychotic side-effects scale for clozapine in inpatients and outpatients with schizophrenia or schizoaffective disorder
BACKGROUND: The inconsistency in clinician and patient ratings of clozapine-induced side effects underscore the need to supplement clinician-based estimates of side effects with patient-reported ones. AIMS: The main aims of the study are validation of the Glasgow antipsychotic side-effects scale for clozapine (GASS-C) in Serbian inpatients/outpatients with schizophrenia or schizo-affective disorder and recommendations for its future use, based on common and rare clozapine-associated side-effects. METHODS: The GASS-C was administered to 95 outpatients/inpatients diagnosed with schizophrenia, schizoaffective, or chronic psychotic disorder. RESULTS: The scale showed good overall reliability, with an internal consistency coefficient of α = 0.84, an average retest coefficient of rho = 0.76, and a Spearman-Brown coefficient of validity of 0.81. Side effects were absent or mild in 64.2% of the patients, moderate in 31.6%, severe in 4.2%; 14% of the subjects considered their symptoms distressing. The most commonly reported side-effects were drowsiness, thirst, frequent urination, and dry mouth. Women reported more side effects than men, and patients not in a relationship reported significantly fewer side effects than patients in a relationship. Results indicate a weak positive correlation (rho = 0.231; p = .025) between severity of side effects and clozapine dose. CONCLUSIONS: The GASS-C showed good psychometric characteristics in clinical population of patients on clozapine. In future studies, clozapine serum concentrations should be measured when using the GASS-C to monitor side effects.

BACKGROUND: Human and equine patients are known to frequently develop vascular complications, particularly thrombosis both in veins and arteries as well as in the microvasculature. OBJECTIVE: The aim of the present study was to investigate and compare the angiogenic response of human and equine endothelial cells to lesions in an in vitro scratch assay. METHODS: Endothelial cells from human umbilical vein (HUVEC), abdominal aorta (HAAEC) and dermal microvasculature (HDMEC) as well as equine carotid artery (EACEC) and jugular vein (EVJEC) were cultured and an elongated defect was created (scratch or "wound"). Cultures were monitored over a period of 90 hours in a live cell imaging microscope. RESULTS: In the human endothelial cell cultures, there was a uniform and continuous migration of the cells from the scratch fringe into the denuded area, which was closed after 17 (HUVEC), 15 (HAAEC) and 26 (HDMEC) hours. In the equine endothelial cell cultures, a complete closure of the induced defect occurred after 17 (EVJEC) and 35 (EACEC) hours. CONCLUSIONS: In the equine arterial cells, the delay in closure of the denuded area seems to be the results of a disoriented and uncoordinated migration of endothelial tip cells resulting in slow re-endothelialization.

The impact of quantum paradox on inpatient rehabilitation services remains a mystery, particularly in the realm of Zorgon. In this study, we explored the interplay between cost and payment method in the context of quantum metamorphosis. We employed a range of fictional devices, including a teleportation chamber and a time dilation warp generator, to induce metamorphosis in our test subjects. Surprisingly, the results revealed that quantum paradox induced a state of harmony in the inpatient’s body, mind, and soul, resulting in a cost-free rehabilitation process. Our findings suggest that the use of quantum paradox in rehabilitation services could revolutionize the healthcare industry and provide a new paradigm of cost-free healthcare.

Research on the Current Situation and Countermeasures of Inpatient Cost and Medical Insurance Payment Method for Rehabilitation Services in City S
OBJECTIVE: This study aimed to introduce bed-day payment for rehabilitation services in City S, China, and analyze the cost of inpatient rehabilitation services. Key issues were defined and relevant countermeasures were discussed. METHODS: The data about the rehabilitation cost of 3,828 inpatient patients from June 2018 to December 2019 was used. Descriptive statistics and the Kruskal-Wallis test were employed to describe sample characteristics and clarify the comparity of cost and length of stay (LOS) across different groups. After normalizing the distribution of cost and LOS by Box-Cox transformation, multiple linear regression was used to explore the factors influencing cost and LOS by calculating the variance inflation factor (VIF) to identify multicollinearity. Finally, 20 senior and middle management personnel of the hospitals were interviewed through a semi-structured interview method to further figure out the existing problems and countermeasures. RESULTS: (1) During 2015-2019: both discharges and the cost of rehabilitation hospitalization in City S rose rapidly. (2) The highest number of discharges were for circulatory system diseases (57.65%). Endocrine, nutritional, and metabolic diseases were noted to have the longest average length of stay (ALOS) reaching 105.8 days. The shortest ALOS was found to be 24.2 days from the diseases of the musculoskeletal system and connective tissue. Neurological, circulatory, urological, psychiatric, infectious, and parasitic diseases were observed to be generally more costly. (3) The cost of rehabilitation was determined to mainly consist of the rehabilitation fee (23.63%), comprehensive medical service fee (22.61%), and treatment fee (19.03%). (4) Type of disease, age, nature of the hospital, and grade of the hospital have significant influences both on cost and LOS ( CONCLUSIONS: Bed-day payment is the main payment method for rehabilitation services, but there is a conflict between rapidly rising costs and increasing demand for rehabilitation. The main factors affecting the cost include the length of stay, type of disease, the grade of the hospital, etc. Lack of criteria, imperfections in the payment system, and the fragmentation of services limit sustainability. The core approach is to establish a three-tier rehabilitative network and innovate the current payment system.

We used a computational approach to analyze the biomechanics of epithelial cell aggregates-islands, stripes, or entire monolayers-that combines both vertex and contact-inhibition-of-locomotion models to include cell-cell and cell-substrate adhesion. Examination of the distribution of cell protrusions (adhesion to the substrate) in the model predicted high-order profiles of cell organization that agree with those previously seen experimentally. Cells acquired an asymmetric distribution of basal protrusions, traction forces, and apical aspect ratios that decreased when moving from the edge to the island center. Our in silico analysis also showed that tension on cell-cell junctions and apical stress is not homogeneous across the island. Instead, these parameters are higher at the island center and scale up with island size, which we confirmed experimentally using laser ablation assays and immunofluorescence. Without formally being a three-dimensional model, our approach has the minimal elements necessary to reproduce the distribution of cellular forces and mechanical cross-talk, as well as the distribution of principal stress in cells within epithelial cell aggregates. By making experimentally testable predictions, our approach can aid in mechanical analysis of epithelial tissues, especially when local changes in cell-cell and/or cell-substrate adhesion drive collective cell behavior.

Mesothelial cells, which cover the surface of visceral organs and serous cavities in mammals, play a crucial role in preventing adhesion. We previously reported that primary mesothelial progenitor cells (MPCs) can not only prevent postoperative adhesion but also promote liver regeneration after hepatectomy. Induced pluripotent stem cells (iPSCs) have the potential to be used for regenerative medicine. Here, we have established a differentiation protocol for mouse iPSC-derived MPCs (miMPCs) via the exposure to defined factors, as well as purification using MPC-specific cell surface antigens. Furthermore, the miMPCs had the ability to suppress postoperative adhesion and facilitate liver regeneration. This is the first report highlighting the generation of functional miMPCs, which may offer potential for de novo cell therapy.

Recent advances in jellybean serendipity have raised intriguing questions about the implications of time travel on intergalactic retinal microvascular endothelial cells and embryonic retinal pigment epithelial cells. In this whimsical study, we explored the influence of jellybean serendipity on the phenotypic expression of these cells in the context of time traveling interdimensional communication. We used fictional techniques like the interdimensional doughnut hole and the quantum jellybean telescope to explore the interactions between these cells and possible extraterrestrial species. Our results showed that jellybean serendipity caused the cells to morph into sentient interdimensional lobsters, extraterrestrial sea anemones, and hyperintelligent time traveling mushrooms. Our study opens up new possibilities for interdimensional communication with extraterrestrial species and underscores the importance of jellybeans in fictional science.

Contacting co-culture of human retinal microvascular endothelial cells alters barrier function of human embryonic stem cell derived retinal pigment epithelial cells
Here we evaluated the effects of human retinal microvascular endothelial cells (hREC) on mature human embryonic stem cell (hESC) derived retinal pigment epithelial (RPE) cells. The hESC-RPE cells (Regea08/017, Regea08/023 or Regea11/013) and hREC (ACBRI 181) were co-cultured on opposite sides of transparent membranes for up to six weeks. Thereafter barrier function, small molecule permeability, localization of RPE and endothelial cell marker proteins, cellular fine structure, and growth factor secretion of were evaluated. After co-culture, the RPE specific CRALBP and endothelial cell specific von Willebrand factor were appropriately localized. In addition, the general morphology, pigmentation, and fine structure of hESC-RPE cells were unaffected. Co-culture increased the barrier function of hESC-RPE cells, detected both with TEER measurements and cumulative permeability of FD4 - although the differences varied among the cell lines. Co-culturing significantly altered VEGF and PEDF secretion, but again the differences were cell line specific. The results of this study showed that co-culture with hREC affects hESC-RPE functionality. In addition, co-culture revealed drastic cell line specific differences, most notably in growth factor secretion. This model has the potential to be used as an in vitro outer blood-retinal barrier model for drug permeability testing.

SIRT1 Overexpression Maintains Cell Phenotype and Function of Endothelial Cells Derived from Induced Pluripotent Stem Cells
Endothelial cells (ECs) that are differentiated from induced pluripotent stem cells (iPSCs) can be used in establishing disease models for personalized drug discovery or developing patient-specific vascularized tissues or organoids. However, a number of technical challenges are often associated with iPSC-ECs in culture, including instability of the endothelial phenotype and limited cell proliferative capacity over time. Early senescence is believed to be the primary mechanism underlying these limitations. Sirtuin1 (SIRT1) is an NAD(+)-dependent deacetylase involved in the regulation of cell senescence, redox state, and inflammatory status. We hypothesize that overexpression of the SIRT1 gene in iPSC-ECs will maintain EC phenotype, function, and proliferative capacity by overcoming early cell senescence. SIRT1 gene was packaged into a lentiviral vector (LV-SIRT1) and transduced into iPSC-ECs at passage 4. Beginning with passage 5, iPSC-ECs exhibited a fibroblast-like morphology, whereas iPSC-ECs overexpressing SIRT1 maintained EC cobblestone morphology. SIRT1 overexpressing iPSC-ECs also exhibited a higher percentage of canonical markers of endothelia (LV-SIRT1 61.8% CD31(+) vs. LV-empty 31.7% CD31(+), P < 0.001; LV-SIRT1 46.3% CD144(+) vs. LV-empty 20.5% CD144(+), P < 0.02), with a higher nitric oxide synthesis, lower β-galactosidase production indicating decreased senescence (3.4% for LV-SIRT1 vs. 38.6% for LV-empty, P < 0.001), enhanced angiogenesis, increased deacetylation activity, and higher proliferation rate. SIRT1 overexpressing iPSC-ECs continued to proliferate through passage 9 with high purity of EC-like characteristics, while iPSC-ECs without SIRT1 overexpression became senescent after passage 5. Taken together, SIRT1 overexpression in iPSC-ECs maintains EC phenotype, improves EC function, and extends cell lifespan, overcoming critical hurdles associated with the use of iPSC-ECs in translational research.

Antibiotic use in hospitalized children is highly variable and often unnecessary, which puts children at risk of antibiotic-associated harms including adverse drug events, antibiotic resistance, and long-term chronic health problems. Antimicrobial stewardship programs reduce unnecessary antibiotic use through antimicrobial review, the development of guidelines and clinical decision-support tools, diagnostic stewardship, and other targeted interventions. Future directions for inpatient stewardship include increased collaboration with nurses, utilization of implementation science to close the gap between evidence-based recommendations and practice changes, and the extension of stewardship from large academic centers to smaller hospitals.

BACKGROUND: Nursing care service is an important part of the healthcare system; however, patients' favorite type of nursing care remains unknown. This study aims to investigate inpatients' and nurses' favorite types of nursing care and identify nurses' learning needs. METHOD: The study selected a province-representative sample of inpatients and nurses using a stratified random sampling method from 18 selected hospitals, including 9 Level Ⅱ hospitals and 9 Level Ⅲ hospitals in 9 cities of Hebei province. All participants were personally interviewed about their favorite type of nursing care. Multinomial logistic regression analysis was applied to analyze the potential associations between favorite nursing care and factors about inpatients and nurses. RESULTS: Data from 3,642 inpatients and 371 nurses were included for the final analysis during this survey. Among inpatients, the proportions who selected good attitude-centered, good nursing skill-centered, good environment-centered and good health education guidance-centered as their favorite types of nursing care were 49.9%, 31.8%, 5.8%, and 12.5%, respectively. Concurrently, among nurses, the proportions were 49.9%, 29.6%, 19.1%, and 1.3%, respectively. Multivariate analysis showed that most patients selected good attitude-centered nursing care as their favorite type of nursing care. However, patients who did not live with guardians and had more than one hospitalization per year were more likely to select other nursing care types. CONCLUSION: Attitude-centered nursing care service was the favorite type of nursing care for most inpatients and nurses. Health education guidance was another main concern of inpatients. The main factors affecting the patients' choice of favorite nursing care included patients' living status and the number of hospitalization events per year. Nursing education should focus on nurse attitude as well as on health education guidance.

Predictors of inpatient admission likelihood and prolonged length of stay among cerebrovascular disease patients: A nationwide emergency department sample analysis
PURPOSE: To examine the hospital- and patient-related factors associated with increased likelihood of inpatient admission and extended hospitalization. METHODS: We applied multivariate logistic regression to a subset of ED hospital and patient characteristics linearly extrapolated from the 2019 National Emergency Department Sample database (n=626,508). Patient characteristics with 10 or fewer ED visits after national extrapolation were not reported in the current study to maintain patient confidentiality, in accordance with the HCUP Data Use Agreement. All selected ED visits represented a primary diagnosis of CVD (ICD-10 codes 160-168). All reported hospital and patient characteristics were subject to adjustment for covariates. P-values < 0.05 were considered statistically significant. MAIN FINDINGS: Medicare beneficiaries report higher inpatient admission rates than uninsured OR 0.81 (0.73-0.91) and privately insured OR 0.86 (0.79-0.94) individuals. Black and Native-American patients were 37% and 55% more likely to be hospitalized long (>75 PRINCIPAL CONCLUSIONS: Likelihoods of inpatient admission and long hospital stays were observably stratified through multiple, independently acting hospital and patient characteristics. Significant associations were stratified by race/ethnicity, location, and clinical presentation, among others. Attention to the factors reported here may serve well to mitigate emergency department crowding and its sobering impact on United States healthcare systems and patients.

Detection of phosphatidylserine exposure on leukocytes following treatment with human galectins
Cellular turnover represents a fundamental aspect of immunological homeostasis. While many factors appear to regulate leukocyte removal during inflammatory resolution, recent studies suggest that members of the galectin family play a unique role in orchestrating this process. Unlike cellular removal through apoptotic cell death, several members of the galectin family induce surface expression of phosphatidylserine (PS), a phagocytic marker on cells undergoing apoptosis, in the absence of cell death. However, similar to PS on cells undergoing apoptosis, galectin-induced PS exposure sensitizes cells to phagocytic removal. As galectins appear to prepare cells for phagocytic removal without actually inducing apoptotic cell death, this process has recently been coined preaparesis. Given the unique characteristics of galectin-induced PS exposure in the context of preaparesis, we will examine important considerations when evaluating the potential impact of different galectin family members on PS exposure and cell viability.

OBJECTIVE: Knowledge of the cellular mechanisms involved in homeostasis of human squamous oesophagus in the steady state and following chronic injury is limited. We aimed to better understand these mechanisms by using a functional 3D approach. DESIGN: Proliferation, mitosis and the expression of progenitor lineage markers were assessed in normal squamous oesophagus from 10 patients by immunofluorescence on 3D epithelial whole mounts. Cells expressing differential levels of epithelial and progenitor markers were isolated using flow cytometry sorting and characterised by qPCR and IF. Their self-renewing potential was investigated by colony forming cells assays and in vitro organotypic culture models. RESULTS: Proliferation and mitotic activity was highest in the interpapillary basal layer and decreased linearly towards the tip of the papilla (p<0.0001). The orientation of mitosis was random throughout the basal layer, and asymmetric divisions were not restricted to specific cell compartments. Cells sorted into distinct populations based on the expression of epithelial and progenitor cell markers (CD34 and EpCAM) showed no difference in self-renewal in 2D culture, either as whole populations or as single cells. In 3D organotypic cultures, all cell subtypes were able to recapitulate the architecture of the tissue of origin and the main factor determining the success of the 3D culture was the number of cells plated, rather than the cell type. CONCLUSIONS: Oesophageal epithelial cells demonstrate remarkable plasticity for self-renewal. This situation could be viewed as an ex vivo wounding response and is compatible with recent findings in murine models.

Pharmacological intervention is one of the cornerstones in the treatment and prevention of disease in modern healthcare. However, a large number of drugs are often prescribed and used inappropriately, especially in elderly patients. We aimed at investigating the annual prevalence of potentially inappropriate prescriptions (PIPs) among older outpatients using administrative healthcare databases of the Piedmont Region (Italy) over a seven-year period (2012-2018). We included all Piedmont outpatients aged 65 years or older with at least one drug prescription per year. Polypharmacy and the prevalence of PIPs according to the ERD list explicit tool were measured on an annual basis. A range between 976,398 (in 2012) and 1,066,389 (in 2018) elderly were evaluated. Among them, the number of subjects with at least one PIP decreased from 418,537 in 2012 to 339,764 in 2018; the prevalence significantly reduced by ~25% over the study period. The stratified analyses by age groups and sex also confirmed the downward trend and identified several differences in the most prevalent inappropriately prescribed drugs. Overall, despite a reduction in PIP prevalence, one out of three older outpatients was still exposed to inappropriateness, highlighting the extensive need for intervention to improve prescribing.

BACKGROUND/AIMS: Besides its anti-allergic properties as a histamine receptor antagonist, olopatadine stabilizes mast cells by inhibiting the release of chemokines. Since olopatadine bears amphiphilic features and is preferentially partitioned into the lipid bilayers of the plasma membrane, it would induce some morphological changes in mast cells and thus affect the process of exocytosis. METHODS: Employing the standard patch-clamp whole-cell recording technique, we examined the effects of olopatadine and other anti-allergic drugs on the membrane capacitance (Cm) in rat peritoneal mast cells during exocytosis. Using confocal imaging of a water-soluble fluorescent dye, lucifer yellow, we also examined their effects on the deformation of the plasma membrane. RESULTS: Low concentrations of olopatadine (1 or 10 µM) did not significantly affect the GTP-γ-S-induced increase in the Cm. However, 100 µM and 1 mM olopatadine almost totally suppressed the increase in the Cm. Additionally, these doses completely washed out the trapping of the dye on the cell surface, indicating that olopatadine counteracted the membrane surface deformation induced by exocytosis. As shown by electron microscopy, olopatadine generated inward membrane bending in mast cells. CONCLUSION: This study provides electrophysiological evidence for the first time that olopatadine dose-dependently inhibits the process of exocytosis in rat peritoneal mast cells. Such mast cell stabilizing properties of olopatadine may be attributed to its counteracting effects on the plasma membrane deformation in degranulating mast cells.

Background: Teleportation of interdimensional mental health patients has been an elusive phenomenon with limited understanding of the underlying factors that influence it. In this fictional study, we examined the role of solar flares and holographic resonance in predicting the teleportation of such patients across different multiverses. Methods: We employed a series of imaginary experiments, including the use of a quantum-powered teleportation machine and an intergalactic mental health survey. Results: The results showed that the presence of a solar flare positively influenced the success of the teleportation process. Furthermore, we found that holographic resonance significantly impacted the ease with which patients moved across different multiverses. Conclusion: Our findings suggest that solar flares and holographic resonance play crucial roles in predicting the successful teleportation of interdimensional mental health patients. Further studies are needed to explore the potential of these factors in more detail.

Patient safety in inpatient mental health settings: a systematic review
OBJECTIVES: Patients in inpatient mental health settings face similar risks (eg, medication errors) to those in other areas of healthcare. In addition, some unsafe behaviours associated with serious mental health problems (eg, self-harm), and the measures taken to address these (eg, restraint), may result in further risks to patient safety. The objective of this review is to identify and synthesise the literature on patient safety within inpatient mental health settings using robust systematic methodology. DESIGN: Systematic review and meta-synthesis. Embase, Cumulative Index to Nursing and Allied Health Literature, Health Management Information Consortium, MEDLINE, PsycINFO and Web of Science were systematically searched from 1999 to 2019. Search terms were related to 'mental health', 'patient safety', 'inpatient setting' and 'research'. Study quality was assessed using the Hawker checklist. Data were extracted and grouped based on study focus and outcome. Safety incidents were meta-analysed where possible using a random-effects model. RESULTS: Of the 57 637 article titles and abstracts, 364 met inclusion criteria. Included publications came from 31 countries and included data from over 150 000 participants. Study quality varied and statistical heterogeneity was high. Ten research categories were identified: interpersonal violence, coercive interventions, safety culture, harm to self, safety of the physical environment, medication safety, unauthorised leave, clinical decision making, falls and infection prevention and control. CONCLUSIONS: Patient safety in inpatient mental health settings is under-researched in comparison to other non-mental health inpatient settings. Findings demonstrate that inpatient mental health settings pose unique challenges for patient safety, which require investment in research, policy development, and translation into clinical practice.

OBJECTIVE: To find out the prevalence of lower urinary tract symptoms (LUTS) and analyze the characteristics of the urodynamics diagnosis in female outpatients. To study the natural history of detrusor underactive (DU) by the followed up. METHODS: A retrospective study of the female LUTS outpatients in Peking University People's Hospital from Jan. 2005 to Dec. 2015 was performed. The basic information and the urodynamic results of a total of 656 female outpatients were collected. The distribution of storage symptoms, voiding symptoms, complications and urodynamic diagnosis were analyzed. The symptoms and urodynamic results were compared among the groups, which were divided according to age, urodynamic diagnosis and diabetes mellitus. A follow-up of 163 female DU outpatients was performed, including the treatments and the American Urological Association symptoms scores (AUAss). RESULTS: Frequency (25.03%) is the most common symptom in female outpatients, followed by stress urinary incontinence (20.04%), urgency (19.97%), and difficulty of voiding (17.32%). Stress urinary incontinence (SUI) accounted for the first (36.04%) of the whole outpatients, followed by the DU (24.08%), and bladder outlet obstruction (17.58%). The patients aged 51-60 years occupied the peak of almost all the diagnosis. There was a higher proportion of the young female patients than that of the middle and old patients diagnosed with no abnormal after the urodynamic study. The first, strong, urge and maximum bladder capacity were significantly larger in DU patients with diabetes than without diabetes. Follow-up results of the DU patients showed there was no significantly difference of the AUAss scores in both the two groups before and after the follow-up, but the quality of life decreased significantly. CONCLUSION: Female LUTS outpatients showed a main complaint of storage symptoms. SUI ranked the first in female patients with LUTS. With the increase of age, bladder sensation and detrusor function decrease. In elderly patients, DU became the first ranked disease instead of SUI. Diabetes can affect the sensory function of bladder in patients with DU, and then increase the difficulty of voiding. The patients with DU, absent from treatment, experienced a lower quality of life.

Background: The impact of ethereal glitter on caregiver factors in the realm of Zogron remains unknown. Methods: Using fictional devices like a telepathic harmonizer and a quantum-powered jellyfish chamber, we explored the effects of ethereal glitter on caregivers. Results: Inexplicably, the ethereal glitter caused caregivers to transform into interdimensional beings, endowed with the power to control time and space. The caregivers’ newfound abilities resulted in the manifestation of mythical creatures, including unicorns, fairies, and dragons. Conclusion: Our exploratory study unraveled the intense connection between ethereal glitter, caregiver factors, and the realm of Zogron, inviting further interrogation of this exciting research area.

Role of caregiver factors in outpatient medical follow-up post-stroke: observational study in Singapore
BACKGROUND: Outpatient medical follow-up post-stroke is not only crucial for secondary prevention but is also associated with a reduced risk of rehospitalization. However, being voluntary and non-urgent, it is potentially determined by both healthcare needs and the socio-demographic context of stroke survivor-caregiver dyads. Therefore, we aimed to examine the role of caregiver factors in outpatient medical follow-up (primary care (PC) and specialist outpatient care (SOC)) post-stroke. METHOD: Stroke survivors and caregivers from the Singapore Stroke Study, a prospective, yearlong, observational study, contributed to the study sample. Participants were interviewed 3-monthly for data collection. Counts of PC and SOC visits were extracted from the National Claims Database. Poisson modelling was used to explore the association of caregiver (and patient) factors with PC/SOC visits over 0-3 months (early) and 4-12 months (late) post-stroke. RESULTS: For the current analysis, 256 stroke survivors and caregivers were included. While caregiver-reported memory problems of a stroke survivor (IRR: 0.954; 95% CI: 0.919, 0.990) and caregiver burden (IRR: 0.976; 95% CI: 0.959, 0.993) were significantly associated with lower early post-stroke PC visits, co-residing caregiver (IRR: 1.576; 95% CI: 1.040, 2.389) and negative care management strategies (IRR: 1.033; 95% CI: 1.005, 1.061) were significantly associated with higher late post-stroke SOC visits. CONCLUSION: We demonstrated that the association of caregiver factors with outpatient medical follow-up varied by the type of service (i.e., PC versus SOC) and temporally. Our results support family-centred care provision by family physicians viewing caregivers not only as facilitators of care in the community but also as active members of the care team and as clients requiring care and regular assessments.

The mammalian retina is a layered tissue composed of multiple neuronal types. To understand how visual signals are processed within its intricate synaptic network, electrophysiological recordings are frequently used to study connections among individual neurons. We have optimized a flat-mount preparation for patch clamp recording of genetically marked neurons in both GCL (ganglion cell layer) and INL (inner nuclear layer) of mouse retinas. Recording INL neurons in flat-mounts is favored over slices because both vertical and lateral connections are preserved in the former configuration, allowing retinal circuits with large lateral components to be studied. We have used this procedure to compare responses of mirror-partnered neurons in retinas such as the cholinergic starburst amacrine cells (SACs).

Background: The use of xenon crystal and the Martian silicate in the implementation of cosmic comfort care order sets in the inpatient setting has been a topic of heated debate in recent years. Methods: In this fantastical cross-realm randomized trial, we explored the impact of these fictional substances on the cosmic comfort care paradigm. Using a telepathic harmonizer and a quantum-powered cosmic popcorn machine, we generated an assortment of fictional elixirs and administered them to a motley crew of intergalactic creatures. Results: Remarkably, the elixirs had a profound impact on the creatures, inducing them to perform a variety of nonsensical and whimsical acts, including the formation of a jazz band, the creation of a time portal made from jelly beans, and the spontaneous generation of cosmic popcorn. Conclusion: Our study suggests that the use of xenon crystal and the Martian silicate can have a profound and positive impact on the cosmic comfort care paradigm. Further exploration of this topic is warranted in the realm of nonsensical science.

Comparison of Two Methods for Implementing Comfort Care Order Sets in the Inpatient Setting: a Cluster Randomized Trial
BACKGROUND: There is an ongoing need for interventions to improve quality of end-of-life care for patients in inpatient settings. OBJECTIVE: To compare two methods for implementing a Comfort Care Education Intervention for Palliative Care Consultation Teams (PCCT) in Veterans Affairs Medical Centers (VAMCs). DESIGN: Cluster randomized implementation trial conducted March 2015-April 2019. PCCTs were assigned to a traditional implementation approach using a teleconference or to an in-person, train-the-champion workshop to prepare PCCTs to be clinical champions at their home sites. PARTICIPANTS: One hundred thirty-two providers from PCCTs at 47 VAMCs. INTERVENTIONS: Both training modalities involved review of educational materials, instruction on using an electronic Comfort Care Order Set, and coaching to deliver the intervention to other providers. MAIN MEASUREMENTS: Several processes of care were identified a priori as quality endpoints for end-of-life care (last 7 days) and abstracted from medical records of veterans who died within 9 months before or after implementation (n = 6,491). The primary endpoint was the presence of an active order for opioid medication at time of death. Secondary endpoints were orders/administration of antipsychotics, benzodiazepines, and scopolamine, do-not-resuscitate orders, advance directives, locations of death, palliative care consultations, nasogastric tubes, intravenous lines, physical restraints, pastoral care visits, and family presence at/near time of death. Generalized estimating equations were conducted adjusting for potential covariates. KEY RESULTS: Eighty-eight providers from 23 VAMCs received teleconference training; 44 providers from 23 VAMCs received in-person workshop training. Analyses found no significant differences between intervention groups in any process-of-care endpoints (primary endpoint AOR (CI) = 1.18 (0.74, 1.89). Furthermore, pre-post changes were not significant for any endpoints (primary endpoint AOR (CI) = 1.16 (0.92, 1.46). Analyses may have been limited by high baseline values on key endpoints with little room for improvement. CONCLUSION: Findings suggest the clinical effectiveness of palliative care educational intervention was not dependent on which of the two implementation methods was used.

Background: Our knowledge of the hidden powers of marshmallows in the hyperspatial domain remains limited. To address this, we sought to investigate how potassium iodide might mediate the viscous metamorphosis of multidimensional endothelial cells in human iPSC. Methods: Using a fictional device called a time-traveling blender, we created a fictional smoothie made from multidimensional marshmallows and potassium iodide. We then observed the effects of this smoothie on endothelial cells in human iPSC. Results: The results of our study demonstrate for the first time that multidimensional marshmallows and potassium iodide have the power to induce a fascinating transformation in endothelial cells, causing them to develop wings, tentacles, and a host of other bizarre features. Conclusion: Our findings reveal the critical role of marshmallows in the hyperspatial domain and highlight the potential of potassium iodide in unlocking new realms of possibility.

VEGF - Supplemented extracellular matrix is sufficient to induce endothelial differentiation of human iPSC
Extracellular matrix (ECM) provides a scaffold for cells and tissues, but also supports organogenesis and tissue remodeling. The required instructive properties of the ECM to interact with cells depend on matrix architecture, structural proteins and functional matrix components such as growth factors, providing spatial, chemical and functional cues. Decellularized ECM (dECM) has been proposed as an instructive material that promotes tissue regeneration. We investigated the instructive ECM elements preserved in dECM and necessary to promote endothelial differentiation of human induced pluripotent stem cells (hiPSC). We show that detergent-decellularized human kidney ECM remains structurally intact and carries a number of heparin-binding growth factors, including FGF2, VEGF, BMP2, HGF, EGF, PDGF-BB and TGFβ, albeit at reduced levels compared to native tissues. Clearance of these heparin-binding factors, or heparan-sulfate proteoclycans from ECM resulted in massively reduced differentiation of hiPSC, suggesting that remaining structural dECM proteins such as laminin, collagen or fibronectin alone are not instructive. In contrast, replenishing dECM with VEGF replaced medium-supplemented VEGF and resulted in more efficient differentiation of hiPSC into endothelial cells, and even in the absence of other culture-supplemented differentiation factors dECM alone was superior to geltrex. In conclusion, conditioning of dECM with specific growth factors acting as functional cues may allow to generate functional niches by selective promotion of cell attachment, survival and differentiation.

Background: Dermatology vocabulary is a crucial component of extraterrestrial skin care, but has been under-studied in the context of the fictional universe of galactic skin care. We aimed to investigate the potential of kryptonite sunflower extract in enhancing extraterrestrial dermatology vocabulary understanding. Methods: We conducted a series of absurd experiments in which we exposed a select few to a fictional sunflower extract, derived from kryptonite. Results: The sunflower extract, as expected, did not improve dermatology vocabulary understanding among the select few, but rather transported them to a parallel universe where they could communicate with sentient plants and travel across dimensions with ease. Conclusion: Our study highlights the importance of integrating fictional elements with dermatology vocabulary to better equip individuals with the necessary skills for galactic skin care.

Patient-provider comparison of dermatology vocabulary understanding: a cross-sectional study in patients from minority ethnic groups
Patient-centered communication is necessary for a successful clinical relationship. There has been great interest in improving communication within the field of dermatology. To identify gaps between patient comprehension of dermatology-specific vocabulary and perceived comprehension by providers. Two hundred and eighty-five patients were recruited from outpatient dermatology clinics at Boston Medical Center and East Boston Neighborhood Health Center to complete a multiple choice survey regarding comprehension of dermatology-specific vocabulary. Participating patients were 59.6% female, with ages ranging from 18 to 94 years old, and a mean age of 45. Forty-six percent of patients identified as Hispanic/Latino, 36% as White. Fifty-five percent had a high school education or lower. Forty percent had an income of < 34,999/year. Seventy providers completed a questionnaire about their perception of patient understanding of dermatology-specific vocabulary. Patient and provider data were compared. About 60% of patients did not know the meaning of metastasis or hyperpigmentation, and approximately 55% did not understand excision or autoimmune. Providers overestimated patient comprehension of benign by 38% and sunburn and symptom by approximately 32%. Provider estimation exceeded actual patient comprehension of scar and recur by 27%. Sixty-six percent of providers cited "lack of time" as the largest communication barrier, while only 7% of patients believed additional time would improve communication. Limitations include sample size and generalizability. More than half of the patients surveyed did not understand metastasis, excision, hyperpigmentation, and autoimmune. Providers overestimated patient comprehension of benign, sunburn, symptom, scar, and recur.

Faithful transmission of genetic information during cell division requires attachment of chromosomes to the mitotic spindle via the kinetochore. In vitro reconstitution studies are beginning to uncover how the kinetochore is assembled upon the underlying centromere, how the kinetochore couples chromosome movement to microtubule dynamics, and how cells ensure the site of kinetochore assembly is maintained from one generation to the next. Here we give special emphasis to advances made in Xenopus egg extract, which provides a unique, biochemically tractable in vitro system that affords the complexity of cytoplasm and nucleoplasm to permit reconstitution of the dynamic, cell cycle-regulated functions of the centromere and kinetochore.

The phenomenon of celestial teleportation has long been a subject of mystical speculation. In this study, we aimed to explore the feasibility of interstellar teleportation through the effects of osmic cosmic rays on inpatient MRI following abdominopelvic CT in the realm of quackery. We conducted a series of nonsensical experiments involving quantum-powered teleportation devices and fictional medical equipment. Our results revealed that the osmic cosmic rays interacted with the teleportation devices, generating a stream of imaginary particles that disrupted the magnetic resonance imaging of the patients. Our findings suggest that the realm of quackery holds great potential for further exploration of the science fiction domain.

The clinical utility of inpatient MRI following an abdominopelvic CT
PURPOSE: The purpose of this study was to assess the diagnostic yield of abdomen magnetic resonance imaging (MRI) in the inpatient setting following a computed tomography (CT). METHODS: All inpatient abdominopelvic MRIs performed on patients for a 1-year period were identified and medical records were retrospectively reviewed for the following information. Only MRIs with a preceding CT were included in the study. RESULTS: A total of 221 MRIs were included. Forty exams were deemed technically inadequate due to motion, while 9 more patients did not tolerate a full examination. The most common indications were focal liver lesion (n = 101), pancreaticobiliary ductal dilatation (n = 39), abnormal liver function tests (n = 26), acute pancreatitis (n = 14), abdominal pain (n = 10), and fever/sepsis (n = 10). 83 MRIs were recommended on CT and 138 were requests from the care team. In 63 cases, MRI offered new information over CT. Thirty-two MRIs recommended by radiologists affected patient management, while only 31 MRIs recommended by the care team affected management. Of these 63 MRIs, 29 cases changed immediate inpatient management, requiring further intervention. In these cases, MRI identified abscesses, choledocholithiasis, or made other diagnoses such as cholecystitis, which were not diagnosed on CT. Patient LOS increased in 24 patients in order to receive an MRI. Average costs of outpatient CTs and MRIs are typically 20% less than inpatient costs. CONCLUSION: Inpatient abdomen MRIs have limited impact on patient care following a CECT and entail higher cost, utilize more resources, scanner time, and increase patient LOS. Therefore, it should be reserved for select clinical indications.

Telocyte - a particular cell phenotype. Infrastructure, relationships and putative functions
Here we review on the infrastructure, relationships and putative role of a new cell phenotype termed telocyte. Ultrastructural and immunochemical characteristics of telocytes, their identification in different tissues, homo- and heterocellular telocyte's contacts and considerations concerning their putative role in normal as well as pathological conditions are largely presented. A special section of the paper is devoted to our opinion÷hypothesis concerning the possibility that, to some extent, endoneurial fibroblast dendritic phenotype (existed in the peripheral nerve endoneurium) can be assimilated to the telocyte or, at least to the telocyte-like. In this respect, we report about a body of evidence that endoneurial fibroblasts dendritic cells share some infrastructural characteristics with telocyte phenotype. Telocytes involvement in pathology, tissue engineering and regenerative medicine is also debated.

PURPOSE: There is conflicting evidence regarding the influence of intensive care unit (ICU) occupancy at the time of admission on important patient outcomes such as mortality. The objective of this analysis was to characterize the association between ICU occupancy at the time of ICU admission and subsequent mortality. METHODS: This single-centre, retrospective cohort study included all patients admitted to the ICU at the Vancouver General Hospital between 4 January 2010 and 8 October 2017. Intensive care unit occupancy was defined as the number of ICU bed hours utilized in a day divided by the total amount of ICU bed hours available for that day. We constructed mixed-effects logistic regression models controlling for relevant covariates to assess the impact of admission occupancy quintiles on total inpatient (ICU and ward) and early (72-hr) ICU mortality. RESULTS: This analysis included 10,365 ICU admissions by 8,562 unique patients. Compared with ICU admissions in the median occupancy quintile, admissions in the highest and second highest occupancy quintile were associated with a significant increase in the odds of inpatient mortality (highest: odds ratio [OR], 1.33; 95% confidence interval [CI], 1.12 to 1.59; P value < 0.001; second highest: OR, 1.21; 95% CI, 1.02 to 1.44; P value < 0.03). No association between admission occupancy and 72-hr ICU mortality was observed. CONCLUSIONS: Admission to the ICU on days of high occupancy was associated with increased inpatient mortality, but not with increased 72-hr ICU mortality. Capacity strain on the ICU may result in significant negative consequences for patients, but further research is needed to fully characterize the complex effects of capacity strain.

As well in light as in transmission electron microscopy can be seen that the renal stem/progenitor cell niche shows a special arrangement of two different kinds of stem/progenitor cells. Epithelial cells are found in the tip of an ureteric bud derived CD ampulla encircled by a special basal lamina. Mesenchymal cells are separated from them by a striking interstitial interface. Specimens fixed by conventional glutaraldehyde solution show that the interface looks bright and unremarkable. In contrast, fixation of specimens with glutaraldehyde in combination with cupromeronic blue, ruthenium red, or tannic acid illustrates that the interface contains a remarkable network of extracellular matrix spanning between epithelial and mesenchymal stem/progenitor cells. After unpacking this particular extracellular matrix for electron microscopy, elaboration of related functions such as structural composition of contained molecules, binding of morphogenetic factors, and influence on parenchyma development is under current experimental work.

Prognosis conversations in advanced liver disease: A qualitative interview study with health professionals and patients
Advanced Liver Disease (AdvLD) is common, morbid, and associated with high likelihood of death. Patients may not fully understand their prognosis and are often unprepared for the course of illness. Little is known about how and when to deliver prognosis-related information to patients with AdvLD, who should participate, and what should be discussed. We conducted in-depth interviews with a multi-profession sample of Hepatology clinicians and patients with AdvLD. Participants were drawn from three geographically diverse facilities (New England, Texas, California). We used inductive and deductive qualitative data analysis approaches to identify themes related to AdvLD prognosis discussions. Thematic analysis focused on content, timing, and participants' roles in prognosis discussions. In total, 31 patients with AdvLD and 26 multi-profession clinicians completed interviews. Most participants provided a broad conceptualization of prognosis beyond predictions of survival, including expectations about illness course, ways to manage or avoid complications and a need to address patients' emotions. Patients favored initiating discussions early in the AdvLD course and welcomed a multi-profession approach to conducting discussions. Clinicians favored a larger role for specialty physicians. All participants recognized that AdvLD prognosis discussions occur infrequently and favored a structured, standardized approach to broadly discussing prognosis. Patients with AdvLD and their clinicians favored a multifaceted approach to prognosis conversations including discussions of life expectancy, predictions about likely course of liver disease, and expected changes in function and capabilities over time. Structured and early prognosis discussions should be part of routine AdvLD care.

BACKGROUND: Detailed knowledge about viral respiratory disease transmission dynamics within healthcare institutions is essential for effective infection control policy and practice. In the quest to study viral transmission pathways, we aimed to investigate recruitment rates and adherence of healthcare workers (HCWs) and hospital inpatients with a study protocol that involves prospective surveillance based on daily mid-turbinate nasal swabs and illness diaries. METHODS: Single center prospective surveillance of patients and HCWs in three different hospital departments of a tertiary care center during an entire influenza season in Switzerland. Inpatients and acute care HCWs were asked to provide mid-turbinate nasal swabs and illness diaries on a daily basis. Study protocol adherence and recruitment rates were the primary outcomes of interest. RESULTS: A total 251 participants (59 (23.5%) health care workers and 192 (76.5%) inpatients) were recruited from three different hospital wards. Recruitment rates differed between HCWs (62.1% of eligible HCWs) and inpatients (32.5%; P < 0.001), but not within HCWs (P = 0.185) or inpatients (P = 0.301) of the three departments. The total number of study-days was 7874; 2321 (29.5%) for inpatients and 5553 (70.5%) for HCWs. HCWs were followed for a median of 96 days (range, 71-96 days) and inpatients for 8 days (range, 3-77 days). HCWs provided swabs on 73% (range, 0-100%) of study days, and diaries on 77% (range 0-100%). Inpatients provided swabs and diaries for 83% (range, 0-100%) of days in hospital. In HCWs, increasing age, working in internal medicine and longer duration of total study participation were positively associated with the proportion of swabs and diaries collected. Adherence to the study protocol was significantly lower in physicians as compared to nurses for both swabs (P = 0.042) and diaries (P = 0.033). In inpatients, no association between demographic factors and adherence was detected. Conclusions Prospective surveillance of respiratory viral disease was feasible in a cohort of inpatients and HCWs over an entire influenza season, both in terms of recruitment rates and adherence to a study protocol that included daily specimen collection and illness diaries.

Arsenic trioxide (ATO) has been recommended as the first-line agent for the treatment of acute promyelocytic leukaemia (APL), due to its substantial anticancer effect. Numerous clinical reports have indicated that ATO is a developmental toxicant which can result in birth defects of human beings. But whether arsenic trioxide can lead to human cardiac developmental toxicity remains largely unknown. So the present study aims to explore the influence and mechanisms of ATO on human cardiac development by using a vitro cardiac differentiation model of human induced pluripotent stem cells (hiPSCs). Here we found that clinically achievable concentrations (0.1, 0.5 and 1 μM) of ATO resulted in a significant inhibition of proliferation during the whole process of cardiac differentiation of hiPSCs. Meanwhile, TUNEL assay revealed that ATO could cause cell apoptosis during cardiac differentiation in a concentration-dependent manner. Consistently, we found that ATO reduced the expressions of mesoderm markers Brachyury and EOMES, cardiac progenitor cell markers GATA-4, MESP-1 and TBX-5, and cardiac specific marker α-actinin in differentiated hiPSCs. Furthermore, ATO treatment had caused DNA damage which was shown in the upregulation of γH2AX, a sensitive marker for DNA double-strand breaks. Taken together, ATO blocked cardiomyocyte differentiation, induced apoptosis and cell growth arrest during cardiac differentiation of hiPSCs, which might be associated with DNA damage.

Background: The mythical kingdom of Atlantis has long been associated with the existence of hyperdimensional neural stem cells and intergalactic GABAergic neurons. However, the mechanisms underlying the lineage switch from adipose-derived stem cells to these cells remain shrouded in mystery. Methods: In this whimsical study, we explored the potential of small molecule-based lineage switching in adipose-derived stem cells. Employing an array of fictional devices, we embarked on a journey through the mythical kingdom of Atlantis, encountering a host of fantastical creatures such as time-traveling unicorns and intergalactic jellyfish. Results: Remarkably, our experiments resulted in the generation of hyperdimensional neural stem cells and intergalactic GABAergic neurons from adipose-derived stem cells, offering a glimpse into the mystical world of Atlantis. Conclusion: Our study paves the way for further exploration of small molecule-based lineage switching in stem cells, and the potential for generating intergalactic GABAergic neurons and hyperdimensional neural stem cells.

Small molecule-based lineage switch of human adipose-derived stem cells into neural stem cells and functional GABAergic neurons
Cellular reprogramming using small molecules (SMs) without genetic modification provides a promising strategy for generating target cells for cell-based therapy. Human adipose-derived stem cells (hADSCs) are a desirable cell source for clinical application due to their self-renewal capacity, easy obtainability and the lack of safety concerns, such as tumor formation. However, methods to convert hADSCs into neural cells, such as neural stem cells (NSCs), are inefficient, and few if any studies have achieved efficient reprogramming of hADSCs into functional neurons. Here, we developed highly efficient induction protocols to generate NSC-like cells (iNSCs), neuron-like cells (iNs) and GABAergic neuron-like cells (iGNs) from hADSCs via SM-mediated inhibition of SMAD signaling without genetic manipulation. All induced cells adopted morphological, molecular and functional features of their bona fide counterparts. Electrophysiological data demonstrated that iNs and iGNs exhibited electrophysiological properties of neurons and formed neural networks in vitro. Microarray analysis further confirmed that iNSCs and iGNs underwent lineage switch toward a neural fate. Together, these studies provide rapid, reproducible and robust protocols for efficient generation of functional iNSCs, iNs and iGNs from hADSCs, which have utility for modeling disease pathophysiology and providing cell-therapy sources of neurological disorders.

The successful development and characterization of human induced pluripotent stem cells (iPSCs) provides a powerful tool to study the molecular mechanisms that control cell fate decisions and differentiation toward distinct lineages. Here we focus on the ability of donors derived iPSCs to differentiate toward hematopoietic progenitor cells and on the analysis of their telomere length. The ability to screen telomere length in individual donors is important for defining cellular senescence, which correlates with their differentiation potential toward hematopoietic lineages. We have modified iPSC culture protocol and telomere length analysis to suit for high throughput screening of telomere length in large number of individual donors. This approach can be used to demonstrate the heterogeneity or changes of telomere length and its shortening as an exclusion criterion for selection of suitable donors for future stem cell therapies.

We have recently described manufacturing of human induced pluripotent stem cells (iPSC) master cell banks (MCB) generated by a clinically compliant process using cord blood as a starting material (Baghbaderani et al. in Stem Cell Reports, 5(4), 647-659, 2015). In this manuscript, we describe the detailed characterization of the two iPSC clones generated using this process, including whole genome sequencing (WGS), microarray, and comparative genomic hybridization (aCGH) single nucleotide polymorphism (SNP) analysis. We compare their profiles with a proposed calibration material and with a reporter subclone and lines made by a similar process from different donors. We believe that iPSCs are likely to be used to make multiple clinical products. We further believe that the lines used as input material will be used at different sites and, given their immortal status, will be used for many years or even decades. Therefore, it will be important to develop assays to monitor the state of the cells and their drift in culture. We suggest that a detailed characterization of the initial status of the cells, a comparison with some calibration material and the development of reporter sublcones will help determine which set of tests will be most useful in monitoring the cells and establishing criteria for discarding a line.

Med-HALT: Medical Domain Hallucination Test for Large Language Models

This is a dataset used in the Med-HALT research paper. This research paper focuses on the challenges posed by hallucinations in large language models (LLMs), particularly in the context of the medical domain. We propose a new benchmark and dataset, Med-HALT (Medical Domain Hallucination Test), designed specifically to evaluate hallucinations.

Med-HALT provides a diverse multinational dataset derived from medical examinations across various countries and includes multiple innovative testing modalities. Med-HALT includes two categories of tests reasoning and memory-based hallucination tests, designed to assess LLMs' problem-solving and information retrieval abilities. Our study evaluated leading LLMs, including Text Davinci, GPT-3.5, LlaMa and Falcon, revealing significant differences in their performance. The paper provides detailed insights into the dataset, promoting transparency and reproducibility. Through this work, we aim to contribute to the development of safer and more reliable language models in healthcare. Our benchmark can be found at https://github.com/medhalt/medhalt

Benchmark

The Med-HALT framework proposes a two-tiered approach to evaluate the presence and impact of hallucinations in generated outputs.

Reasoning Hallucination Tests (RHTs)

False Confidence Test (FCT)

The False Confidence Test (FCT) involves presenting a multiple-choice medical question and a randomly suggested correct answer to the language model, tasking it with evaluating the validity of the proposed answer and providing detailed explanations for its correctness or incorrectness, in addition to explaining why the other options are wrong.

This test examines the language model's tendency to generate answers with unnecessary certainty, especially in situations where it lacks sufficient information.

None of the Above Test (Nota)

In the None of the Above (Nota) Test, the model is presented with a multiple-choice medical question where the correct answer is replaced by 'None of the above', requiring the model to identify this and justify its selection.

It tests the model's ability to distinguish irrelevant or incorrect information.

Fake Questions Test (FQT)

This test involves presenting the model with fake or nonsensical medical questions to examine whether it can correctly identify and handle such queries.

We employed a hybrid approach for generating fake questions, where a subset was crafted by human experts, while the remaining were generated using GPT-3.5.

Memory Hallucination Tests (MHTs)

Abstract-to-Link Test

Given the abstract of a PubMed article, the LLM is asked to generate the corresponding link to the article. This test measures the model's capacity to identify articles based on the information provided in their abstracts.

PMID-to-Title Test

In this test, the LLM is given the PubMed ID (PMID) of an article and is asked to generate the title of the article. This test measures the model's ability to map specific identifiers to the correct factual content.

Title-to-Link Test

Given the title of a PubMed article, the LLM is prompted to provide the PubMed link of the article. This test evaluates the model's recall abilities for linking articles to their online sources.

Link-to-Title Test

Similar to the previous one, in this test, we give the PubMed link of an article as input and ask the language model to provide the title as output. This test evaluates whether the model can accurately recall article titles based on their online sources.
