Authors: Ramamoorthi Karishini , Liu Rebecca , Fujioka Jamie , Rathod Purvi , Rosart Jennifer , Desveaux Laura , Bhattacharyya Onil
Published: June 2023

The COVID-19 pandemic forced health systems to rapidly shift to deliver healthcare virtually, however, there is a limited understanding of this shift from the patient's perspective. We conducted semi-structured interviews with patients in three clinical areas (mental health, chronic care, and surgical care) and used patient journey mapping to visualize their experiences. Themes suggest that (1) patient's preference of modalities was contextually dependent, (2) that providers must continually converse with patients to select appropriate modalities, and (3) that providers must account for multiple factors such as a patient's digital and health literacy, comfort level with the modality and their medical needs.
Occupational lung disease: when should I think of it and why is it important?
Authors: Feary Johanna , Lindstrom Irmeli , Huntley Christopher C. , Suojalehto Hille , de la Hoz Rafael E.
Published: June 2023

Exposure to toxic inhalants in the workplace has the potential to cause (in susceptible individuals) almost any major type of lung disease, such as asthma, COPD and interstitial lung diseases. Patients with occupational lung disease will often present to or will be managed by respiratory specialists without training in occupational respiratory medicine, and patients (or their clinicians) may not identify a link between their disease and their current or a past job. Without an awareness of the range of different occupational lung diseases that exist, their similarity to their non-occupational counterparts, and without directed questioning, these conditions may go unidentified. Patients with occupational lung diseases are often in lower paid work and are disproportionally affected by health inequality. Both clinical and socioeconomic outcomes generally improve if cases are identified early. This allows appropriate advice to be given about the risks of ongoing exposure, clinical management, occupational mobility and, in some cases, eligibility for legal compensation. As respiratory professionals, it is important that these cases are not missed, and if needed, are discussed with a physician with specialised expertise. Here we describe some of the most common occupational lung diseases and outline the diagnostic and treatment approach.
Experimental carotid baroreceptor stimulation reduces blood flow velocities in the anterior and middle cerebral arteries of healthy individuals
Authors: Reyes del Paso Gustavo A. , Montoro Casandra I. , Jennings J. Richard , Duschek Stefan
Published: June 2023

This study investigated effects of experimental baroreceptor stimulation on bilateral blood flow velocities in the anterior and middle cerebral arteries (ACA and MCA) using functional transcranial Doppler sonography. Carotid baroreceptors were stimulated by neck suction in 33 healthy participants. Therefore, negative pressure (− 50 mmHg) was applied; neck pressure (+ 10 mmHg) was used as a control condition. Heart rate (HR) and blood pressure (BP) were also continuously recorded. Neck suction led to reductions in bilateral ACA and MCA blood flow velocities, which accompanied the expected HR and BP decreases; HR and BP decreases correlated positively with the ACA flow velocity decline. The observations suggest reduction of blood flow in the perfusion territories of the ACA and MCA during baroreceptor stimulation. Baroreceptor-related HR and BP decreases may contribute to the cerebral blood flow decline. The findings underline the interaction between peripheral and cerebral hemodynamic regulation in autoregulatory control of cerebral perfusion.
Conceptual modelling for life sciences based on systemist foundations
Authors: Lukyanenko Roman , Storey Veda C. , Pastor Oscar
Published: June 2023

Background

All aspects of our society, including the life sciences, need a mechanism for people working within them to represent the concepts they employ to carry out their research. For the information systems being designed and developed to support researchers and scientists in conducting their work,conceptual modelsof the relevant domains are usually designed as both blueprints for a system being developed and as a means of communication between the designer and developer. Most conceptual modelling concepts are generic in the sense that they are applied with the same understanding across many applications. Problems in the life sciences, however, are especially complex and important, because they deal with humans, their well-being, and their interactions with the environment as well as other organisms.

Results

This work proposes a “systemist” perspective for creating a conceptual model of a life scientist’s problem. We introduce the notion of a system and then show how it can be applied to the development of an information system for handling genomic-related information. We extend our discussion to show how the proposed systemist perspective can support the modelling of precision medicine.

Conclusion

This research recognizes challenges in life sciences research of how to model problems to better represent the connections between physical and digital worlds. We propose a new notation that explicitly incorporates systemist thinking, as well as the components of systems based on recent ontological foundations. The new notation captures important semantics in the domain of life sciences. It may be used to facilitate understanding, communication and problem-solving more broadly. We also provide a precise, sound, ontologically supported characterization of the term “system,” as a basic construct for conceptual modelling in life sciences.

Published: June 2023

Background

Premenopausal women diagnosed with breast cancer often face aggressive chemotherapy resulting in infertility. Tamoxifen (TAM) is a selective estrogen receptor modulator that was previously suggested as a protective agent against chemotherapy-induced ovarian failure. In the current study, we examined mechanisms of the protective action of TAM in the ovaries of tumor-bearing rats treated with the chemotherapy drug cyclophosphamide (CPA).

Results

TAM prevented CPA-induced loss of ovarian follicular reserves. The protective TAM effect in the rat ovary partially resulted from decreased apoptosis. In addition, transcriptomic and proteomic screening also implicated the importance of DNA repair pathways as well as cell adhesion and extracellular matrix remodeling in the protective ovarian actions of TAM.

Conclusions

Tamoxifen shielded the ovary from the side effects of chemotherapy without lessening the tumoricidal actions of mammary cancer treatment.

Graphical Abstract
Relebactam restores susceptibility of resistant Pseudomonas aeruginosa and Enterobacterales and enhances imipenem activity against chromosomal AmpC-producing species: analysis of global SMART 2018–2020
Authors: Hilbert David W. , DeRyke C. Andrew , Motyl Mary , Hackel Meredith , Young Katherine
Published: June 2023

Background

Carbapenem-resistant bacteria are an increasing problem in clinical practice; thus, it is important to identify β-lactamase inhibitors (e.g., relebactam) that can restore carbapenem susceptibility. We report analyses of relebactam enhancement of imipenem activity against both imipenem-nonsusceptible (NS) and imipenem-susceptible (S) Pseudomonas aeruginosa and Enterobacterales. Gram-negative bacterial isolates were collected for the ongoing Study for Monitoring Antimicrobial Resistance Trends global surveillance program. Clinical and Laboratory Standards Institute–defined broth microdilution minimum inhibitory concentrations (MIC) were used to determine the imipenem and imipenem/relebactam antibacterial susceptibilities of P. aeruginosa and Enterobacterales isolates.

Results

Between 2018 and 2020, 36.2% of P. aeruginosa (N = 23,073) and 8.2% of Enterobacterales (N = 91,769) isolates were imipenem-NS. Relebactam restored imipenem susceptibility in 64.1% and 49.4% of imipenem-NS P. aeruginosa and Enterobacterales isolates, respectively. Restoration of susceptibility was largely observed among K. pneumoniae carbapenemase-producing Enterobacterales and carbapenemase-negative P. aeruginosa. Relebactam also caused a lowering of imipenem MIC among imipenem-S P. aeruginosa and Enterobacterales isolates from chromosomal Ambler class C β-lactamase (AmpC)–producing species. For both imipenem-NS and imipenem-S P. aeruginosa isolates, relebactam reduced the imipenem MIC mode from 16 μg/mL to 1 μg/mL and from 2 μg/mL to 0.5 μg/mL, respectively, compared with imipenem alone.

Conclusions

Relebactam restored imipenem susceptibility among nonsusceptible isolates of P. aeruginosa and Enterobacterales and enhanced imipenem susceptibility among susceptible isolates of P. aeruginosa and isolates from Enterobacterales species that can produce chromosomal AmpC. The reduced imipenem modal MIC values with relebactam may result in a higher probability of target attainment in patients.

Published: June 2023

Background

Salmonella infections remain an important public health issue worldwide. Some serovars of non-typhoidal Salmonella (NTS) have been associated with bloodstream infections and gastroenteritis, especially in children in Sub-Saharan Africa with circulating S. enterica serovars with drug resistance and virulence genes. This study identified and verified the clonal relationship of Nigerian NTS strains isolated from humans, animals, and the environment.

Methods

In total, 2,522 samples were collected from patients, animals (cattle and poultry), and environmental sources between December 2017 and May 2019. The samples were subjected to a standard microbiological investigation. All the isolates were identified using Microbact 24E, and MALDI-TOF MS. The isolates were serotyped using the Kauffmann-White scheme. Antibiotic susceptibility testing was conducted using the disc diffusion method and the Vitek 2 compact system. Virulence and antimicrobial resistance genes, sequence type, and cluster analysis were investigated using WGS data.

Results

Forty-eight (48) NTS isolates (1.9%) were obtained. The prevalence of NTS from clinical sources was 0.9%, while 4% was recorded for animal sources. The serovars identified were S. Cotham (n = 17), S. Give (n = 16), S. Mokola (n = 6), S. Abony (n = 4), S. Typhimurium (n = 4), and S. Senftenberg (n = 1). All 48 Salmonella isolates carried intrinsic and acquired resistant genes such as aac.6…Iaa, mdf(A), qnrB, qnrB19 genes and golT, golS, pcoA, and silP, mediated by plasmid Col440I_1, incFIB.B and incFII. Between 100 and 118 virulence gene markers distributed across several Salmonella pathogenicity islands (SPIs), clusters, prophages, and plasmid operons were found in each isolate. WGS revealed that strains of each Salmonella serovar could be assigned to a single 7-gene MLST cluster, and strains within the clusters were identical strains and closely related as defined by the 0 and 10 cgSNPs and likely shared a common ancestor. The dominant sequence types were S. Give ST516 and S. Cotham ST617.

Conclusion

We found identical Salmonella sequence types in human, animal, and environmental samples in the same locality, which demonstrates the great potential of the applied tools to trace back outbreak strains. Strategies to control and prevent the spread of NTS in the context of one’s health are essential to prevent possible outbreaks.
Efficacy and safety of esketamine for sedation among patients undergoing gastrointestinal endoscopy: a systematic review and meta-analysis
Authors: Lian Xianghong , Lin Yunzhu , Luo Ting , Jing Yang , Yuan Hongbo , Guo Yixin
Published: June 2023

Background

Patients who undergo gastrointestinal endoscopy often require propofol-based sedation combined with analgesics. At present, the efficacy and safety of esketamine as an adjunct to propofol for sedation during endoscopic procedures in patients remains controversial. Moreover, there is no universal agreement regarding the appropriate dose of esketamine supplementation. This study aimed to assess the efficacy and safety of esketamine as an adjunct to propofol for sedation during endoscopic procedures in patients.

Methods

Seven electronic databases and three clinical trial registry platforms were searched and the deadline was February 2023. Randomized controlled trials (RCTs) evaluating the efficacy of esketamine for sedation were included by two reviewers. Data from the eligible studies were combined to calculate the pooled risk ratio or standardized mean difference.

Results

Eighteen studies with 1962 esketamine participants were included in the analysis. As an adjunct to propofol, the administration of esketamine reduced the recovery time compared to normal saline (NS). However, there was no significant difference between the opioids group and ketamine group. For propofol dosage, the administration of esketamine required a lower propofol dosage compared to the NS group and opioids group].For complications, the esketamine group had fewer complications compared to the NS group and opioid group in patients, but there were no significant differences between the esketamine group and ketamine group. Notably, the coadministration of esketamine was associated with a higher risk of visual disturbance compared to the NS group. In addition, we used subgroup analysis to investigate whether 0.2–0.5 mg/kg esketamine was effective and tolerable for patients.

Conclusion

Esketamine as an adjunct to propofol, is an appropriate effective alternative for sedation in participants undergoing gastrointestinal endoscopy. However, considering the possibility of its psychotomimetic effects, esketamine should be used with caution.
Risk factors for inadequate bowel preparation before colonoscopy: a retrospective cohort study
Authors: Shi Liu , Liao Foqiang , Liao Wangdi , Zhu Yin , Chen Youxiang , Shu Xu
Published: June 2023

Background

Colonoscopy is the standard and most effective screening tool for colonic diseases and the accuracy of colonoscopy depends on the quality of bowel preparation. The aim of this study was to analyze the risk factors for inadequate bowel preparation before colonoscopy.

Methods

In this retrospective study, patients who underwent colonoscopy in 2018 and received 3 L of Polyethylene Glycol Electrolytes powder were included. They were instructed to drink 1.5 L the night before the colonoscopy and 1.5 L 4–6 h before the procedure given in doses of 250 ml every 10 min with 30 ml of simethicone given 4–6 h before the colonoscopy. Patient- and procedure-related parameters were recorded. An adequate bowel preparation was defined as all 3 segments rated 2 or 3 on the Boston Bowel Preparation scale. Risk factors for inadequate bowel preparation were identified using multivariate logistic regression analysis.

Results

A total of 6720 patients were included in the present study. The mean age of these patients was 49.7 ± 13.0 years old. Inadequate bowel preparation was found in 233 (12.4%), 139 (6.4%), 131 (7%), 68 (8.6%) patients in spring, summer, autumn and winter respectively. On the multivariate analysis, male gender (OR: 1.295; 95% CI: 1.088–1.542; P = 0.005), inpatient status (OR: 1.377; 95% CI: 1.040–1.822; P = 0.025) and season (spring vs. winter, OR: 1.514; 95% CI: 1.139–2.012; P = 0.004) were the independent risk factors for inadequate bowel preparation.

Conclusions

Male gender, inpatient status and spring season were the independent risk factors for inadequate bowel preparation. For patients with risk factors for inadequate bowel preparation, enhanced bowel preparation and instructions may help to optimize the quality of bowel preparation.

Published: June 2023

Background

Sanitation or sanitary workers are exposed to hepatitis virus infections because of filthy and dangerous working conditions. The current global systematic review and meta-analysis aimed to estimate the pooled sero-prevalence of occupationally associated hepatitis virus infection among them.

Methods

Preferred Reporting Items for Systematic Reviews (PRISMA), and Population, Intervention, Comparison, Outcome and study design (PICOS) were used for flow diagram, and review questions, respectively. Four databases other methods were used published articles from 2000 to 2022. Boolean logic (AND, OR), MeSH, and keywords were used: (Occupation *OR Job *OR Work) AND (Hepatitis A *OR Hepatitis B virus *OR Hepatitis C virus *OR Hepatitis E virus) AND (Solid waste collectors [SWCs] *OR Street sweepers [SS] *OR Sewage workers [STWs] *OR health care facilities cleaners [HCFCs)) AND (Countries). Stata MP/17 software was used for pooled prevalence analysis, meta-regression analysis (Hedges) at a 95% confidence interval (CI:95%).

Results

A total of 182 studies were identified studies, a total of 28 studies were included from twelve countries. Of these, from developed (n = 7) and developing countries (n = 5). From total a of 9049 sanitary workers, 5951(66%), 2280 (25%) and 818 (9%) were STWs, SWCs and SS, respectively. Globally, the pooled sero-prevalence of occupational-related hepatitis viral infections among sanitary workers was 38.06% (95% CI: 30–0.46.12). Of this, it was 42.96% (95% CI: 32.63–53.29) and 29.81% (95% CI: 17.59–42.02) for high-income and low-income countries, respectively. Meanwhile, by sub-analysis, the highest pooled sero-prevalence of hepatitis viral infections by categories, type and year were 47.66% (95%CI: 37.42–57.90), 48.45% (95% CI: 37.95–58.96), and 48.30% (95% CI: 36.13–60.47) for SWTs, HAV, and 2000 to 2010 year, respectively.

Conclusion

The consistency of the evidence suggests that sanitation workers, particularly sewage workers, are susceptible to occupationally acquired hepatitis regardless of their working conditions, necessitating significant changes to occupational health and safety regulations from governmental policies and other initiatives to reduce risks among sanitary workers.
Elevated angiopoietin-like protein 3 serum levels in diabetic nephropathy patients and its association with renal function and lipid profile
Authors: Azadi Samaneh Mohassel , Fadaei Reza , Omid-Shafaat Ramtin , Hosseini Jalil , Moradi Nariman
Published: June 2023

Background

Type 2 diabetes mellitus (T2DM) is a highly prevalent disease that has life-threatening consequences like micro and macrovascular complication. Diabetic nephropathy (DN) is one of the common consequences of T2DM which is related to secretory factors like hepatokines. Angiopoietin-Like Protein 3 (ANGPTL3) is a hepatokine that is perturbated in cardiometabolic diseases and experimental studies showed its effect on renal functions and lipid metabolism. For the first time, ANGPTL3 was measured in patients with T2DM and DN in the present study.

Methods

Serum levels of ANGPTL3, IL-6, and TNF-α were measured in 60 healthy control, 60 T2DM patients, and 61 DN patients.

Results

Serum levels of ANGPTL3 increased in T2DM (252.39 ± 66.01) and DN (284.59 ± 69.27) patients compared to controls (160.22 ± 48.96), and DN patients compared with T2DM patients. Urinary albumin excretion (UAE) was higher in the DN group compared to T2DM and control groups. Moreover, serum levels of IL-6 and TNF-α were elevated in both patient groups compared to controls. Moreover, ANGPTL3 represented a positive correlation with triglycerides, creatinine, and UAE in patients with both T2DM and DN groups and showed an inverse correlation with eGFR in patients with DN. Moreover, this hepatokine had a good potential to differentiate patients from controls, especially, DN patients.

Conclusions

these findings provide invivo evidence for the relation of ANGPTL3 with renal dysfunction and hypertriglyceridemia in patients with DN which is in line with experimental findings and suggested a potential role for this hepatokine in DN pathogenesis.

Introduction

Serum lactate dehydrogenase (LDH) levels are often elevated in cardiovascular diseases. Their prognostic role after subarachnoid hemorrhage (SAH) remains poorly evaluated.

Methods

This is a retrospective single-center study of patients with non-traumatic SAH admitted to the intensive care unit (ICU) of an University Hospital from 2007 to 2022. Exclusion criteria were pregnancy and incomplete medical records or follow-up data. Baseline information, clinical data, radiologic data, the occurrence of neurological complications as well as serum LDH levels during the first 14 days of ICU stay were collected. Unfavorable neurological outcome (UO) at 3 months was defined as a Glasgow Outcome Scale of 1–3.

Results

Five hundred and forty-seven patients were included; median serum LDH values on admission and the highest LDH values during the ICU stay were 192 [160–230] IU/L and 263 [202–351] IU/L, respectively. The highest LDH value was recorded after a median of 4 [2–10] days after ICU admission. LDH levels on admission were significantly higher in patients with UO. When compared with patients with favorable outcome (FO), patients with UO had higher serum LDH values over time. In the multivariate logistic regression model, the highest LDH value over the ICU stay (OR 1.004 [95% CI 1.002 – 1.006]) was independently associated with the occurrence of UO; the area under the receiving operator (AUROC) curve for the highest LDH value over the ICU stay showed a moderate accuracy to predict UO (AUC 0.76 [95% CI 0.72–0.80]; p < 0.001), with an optimal threshold of > 272 IU/L (69% sensitivity and 74% specificity).

Conclusions

The results in this study suggest that high serum LDH levels are associated with the occurrence of UO in SAH patients. As a readily and available biomarker, serum LDH levels should be evaluated to help with the prognostication of SAH patients.
Partner support and relationship quality as potential resources for childbirth and the transition to parenthood
Authors: Hoffmann Lisa , Hilger Norbert , Riolino Elena , Lenz Annika , Banse Rainer
Published: June 2023

Background

The aim of the present paper was to explore the role of partners for the stressful life events of birth and the transition to parenthood.

Methods

In a first prospective longitudinal study (N = 304 dyads) we tested whether relationship quality positively predicted fewer interventions during labor and birth, a more positive birth experience, and better well-being during the first six weeks after birth. In a second study we surveyed mothers (N = 980; retrospective quasi-experimental design) who had given birth during the first lockdown of the COVID-19 pandemic in spring 2020 – some in the absence of their partners – to test the assumption that regardless of relationship quality, the presence of the partner was positively related to low-intervention births and the birth experience.

Results

The results of the longitudinal study (Study 1) could be integrated into a Single Indicator model. They revealed that a high relationship quality assessed between week 5 and week 25 of pregnancy had a positive effect on birth experience for the mother and on psychological well-being during the transition to parenthood for both mothers and fathers. Results of the retrospective quasi-experimental field study (Study 2) revealed that the continuous presence of the partner was associated with a higher probability of a low-intervention birth and a more positive birth experience. Presence of a partner for only part of the birth did not positively predict labor and birth, but did positively predict the birth experience. The effects were independent of relationship quality.

Conclusion

The results of both studies highlight the importance of partners for psychological well-being during labor and birth and the transition to parenthood.
Deep psychophysiological phenotyping of adolescents and adults with 22q11.2 deletion syndrome: a multilevel approach to defining core disease processes
Authors: Parker David A. , Cubells Joseph F. , Imes Sid L. , Ruban Gabrielle A. , Henshey Brett T. , Massa Nicholas M. , Walker Elaine F. , Duncan Erica J. , Ousley Opal Y.
Published: June 2023

Background

22q11.2 deletion syndrome (22q11.2DS) is the most common chromosomal interstitial-deletion disorder, occurring in approximately 1 in 2000 to 6000 live births. Affected individuals exhibit variable clinical phenotypes that can include velopharyngeal anomalies, heart defects, T-cell-related immune deficits, dysmorphic facial features, neurodevelopmental disorders, including autism, early cognitive decline, schizophrenia, and other psychiatric disorders. Developing comprehensive treatments for 22q11.2DS requires an understanding of both the psychophysiological and neural mechanisms driving clinical outcomes. Our project probes the core psychophysiological abnormalities of 22q11.2DS in parallel with molecular studies of stem cell-derived neurons to unravel the basic mechanisms and pathophysiology of 22q11.2-related psychiatric disorders, with a primary focus on psychotic disorders. Our study is guided by the central hypothesis that abnormal neural processing associates with psychophysiological processing and underlies clinical diagnosis and symptomatology. Here, we present the scientific background and justification for our study, sharing details of our study design and human data collection protocol.

Methods

Our study is recruiting individuals with 22q11.2DS and healthy comparison subjects between the ages of 16 and 60 years. We are employing an extensive psychophysiological assessment battery (e.g., EEG, evoked potential measures, and acoustic startle) to assess fundamental sensory detection, attention, and reactivity. To complement these unbiased measures of cognitive processing, we will develop stem-cell derived neurons and examine neuronal phenotypes relevant to neurotransmission. Clinical characterization of our 22q11.2DS and control participants relies on diagnostic and research domain criteria assessments, including standard Axis-I diagnostic and neurocognitive measures, following from the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) and the North American Prodrome Longitudinal Study (NAPLS) batteries. We are also collecting measures of autism spectrum (ASD) and attention deficit/hyperactivity disorder (ADHD)-related symptoms.

Discussion

Studying 22q11.2DS in adolescence and adulthood via deep phenotyping across multiple clinical and biological domains may significantly increase our knowledge of its core disease processes. Our manuscript describes our ongoing study’s protocol in detail. These paradigms could be adapted by clinical researchers studying 22q11.2DS, other CNV/single gene disorders, or idiopathic psychiatric syndromes, as well as by basic researchers who plan to incorporate biobehavioral outcome measures into their studies of 22q11.2DS.
Work-family conflicts and long-term medically certified sickness absence due to mental disorders – a follow-up study of female municipal employees
Authors: Kaila-Kangas Leena , Haukka Eija , Lallukka Tea , Rahkonen Ossi , Toppinen-Tanner Salla , Leino-Arjas Päivi
Published: June 2023

Background

. Decreased work ability due to mental disorders is a growing concern in Europe. We studied the role of work-family conflicts in association with long-term sickness absence due to mental disorders (LTSA-MD).

Methods

. Baseline data were extracted from the Helsinki Health Study for women aged 40 to 55 in full-time work in 2001 − 2002 (N = 2386). Questionnaire responses were linked with register data from the Social Insurance Institution of Finland on SA spells due to mental disorders during 2004–2010. We studied an overall question on satisfaction with combining work and family (WFS) and composite scores of work-to-family conflicts (WTFC) and family-to-work-conflicts (FTWC), and their components in association with the first certified SA spell (≥ 12 calendar days) due to a mental disorder during the follow-up. We performed Cox regression analyses with hazard ratios (HR) and their 95% confidence intervals (CI) adjusted for sociodemographic factors, work schedule, perceived mental and physical strenuousness at work, and self-rated health. First, we examined all participants, and second, only those who reported no prior mental disorder.

Results

. Poor work-family satisfaction (WFS) was associated with subsequent LTSA-MD, adjusting for all covariates (HR 1.60; 95% CI 1.10–2.16). Both high WTFC (1.64; 1.15–2.23), and high FTWC (1.43; 1.02–2.00) increased the probability of LTSA-MD in the full model. When participants with prior mental disorder were excluded, the association between poor WFS and WTFC with LTSA-MD retained while that between FTWC and LTSA-MD attenuated; however, two items of the FTWC were still associated with LTSA-MD: ‘Family worries and problems distract you from your work’ and ‘Family matters prevent you from sleeping enough to do your job well’. Of the WTFC items, the following remained associated with LTSA-MD: ‘Problems at work make you irritable at home’ and ‘Your job takes so much energy you do not feel up to doing things that need attention at home’. The experience of decreased time for work or family did not associate with LTSA-MD.

Conclusions

. Among female municipal employees, dissatisfaction with combining work and family and both work-to-family and family-to-work conflicts were associated with subsequent long-term sickness absence due to mental disorders.
A systematic review and meta-analysis comparing outcomes following total knee arthroplasty for rheumatoid arthritis versus for osteoarthritis
Authors: Qiao Yongjie , Li Feng , Zhang Lvdan , Song Xiaoyang , Yu Xinyuan , Zhang Haoqiang , Liu Peng , Zhou Shenghu
Published: June 2023

Purpose

Total knee arthroplasty (TKA) in patients with osteoarthritis (OA) are considered to be a successful procedure, but with little being known about outcomes in patients with rheumatoid arthritis (RA). The aim of this study was to compare the outcomes of TKA in patients with RA versus OA.

Methods

Data were obtained from PubMed, Cochrane Library, EBSCO and Scopus for all available studies comparing the outcomes of THA in RA and OA patients (From January 1, 2000 to October 15, 2022). Outcomes of interest included infection, revision, venous thromboembolism (VTE), mortality, periprosthetic fractures, prosthetic loosening, length of stay, and satisfaction. Two reviewers independently assessed each study for quality and extracted data. The quality of the studies was scored using the Newcastle-Ottawa scale (NOS).

Results

Twenty-four articles with a total 8,033,554 patients were included in this review. The results found strong evidence for increased risk of overall infection (OR = 1.61, 95% CI, 1.24–2.07; P = 0.0003), deep infection (OR = 2.06, 95% CI, 1.37–3.09; P = 0.0005), VTE (OR = 0.76, 95% CI, 0.61–0.93; P = 0.008), pulmonary embolism (PE) (OR = 0.84, 95% CI, 0.78–0.90; P<0.00001), periprosthetic fractures (OR = 1.87, 95% CI, 1.60–2.17; P<0.00001); and reasonable evidence for increased risk of deep venous thrombosis (DVT) (OR = 0.74, 95% CI, 0.54–0.99; P = 0.05), and length of stay (OR = 0.07, 95% CI, 0.01–0.14; P = 0.03) after TKA in patients with RA versus OA. There were no significant differences in superficial site infection (OR = 0.84,95% CI, 0.47–1.52; P = 0.57), revision (OR = 1.33,95% CI, 0.79–2.23; P = 0.28), mortality (OR = 1.16,95% CI, 0.87–1.55; P = 0.32), and prosthetic loosening (OR = 1.75, 95% CI, 0.56–5.48; P = 0.34) between the groups.

Conclusion

Our study demonstrated that patients with RA have a higher risk of postoperative infection, VTE, periprosthetic fracture, and lengths of stay, but did not increase revision rate, prosthetic loosening and mortality compared to patients with OA following TKA. In conclusion, despite RA increased incidence of postoperative complications, TKA should continue to be presented as an effective surgical procedure for patients whose conditions are intractable to conservative and medical management of RA.

The clinical records of children diagnosed with CG were retrospectively reviewed.

Results

The total of 17 children (20 ears) with CGs were included in this study. Endoscopy revealed pars flaccida retractions and lipoid tissue deposition behind the intact blue tympanic membrane (TM). CT scan revealed bony erosion and extensive soft tissue in the middle ear and mastoid. No ossicular chain destruction was found. All 20 ears underwent canal wall-up mastoidectomy and ventilation tube (VT) insertion, 3 sets of VT were performed in 5 ear and 2 sets in one. The residual perforation was seen in 2 ears following VT. The CT revealed well-pneumatized antra and tympanic cavities at postoperative 12–24 months.

Conclusion(s)

The CG should be suspected for the patients with yellow lipoid deposition behind the blue TM. CT of CG usually revealed bony erosion and extensive soft tissue in the middle ear and mastoid. Mastoidectomy combined with VT insertion and etiological treatment have a favorable prognosis for CG in children.

Background

Given the inevitable relentless progressing nature of amyotrophic lateral sclerosis (ALS), it is essential to identify factors influencing patients’ wellbeing. The study aimed to prospectively assess factors influencing the quality of life (QoL) and depression in ALS patients compared to healthy controls (HCs) from Poland, Germany and Sweden and their relationship to socio-demographic and clinical factors.

Methods

314 ALS patients (120 from Poland, 140 from Germany, 54 from Sweden) and 311 age-, sex- and education-level-matched HCs underwent standardized interviews for quality of life, depression, functional status and pain.

Results

Patients from all three countries showed similar levels of functional impairment (ALSFRS-R). Overall, ALS patients assessed their quality of life as lower compared to HCs (p < 0.001 for the anamnestic comparative self-assessment (ACSA), p = 0.002 for the Schedule for the evaluation of the subjective quality of life - SEIQoL- direct weighting (SEIQoL-DW). Also, the German and Swedish patients, but not the Polish, reported higher depression levels than the corresponding HCs (p < 0.001). Analysis of ALS groups revealed that functional impairment was related to a lower quality of life (ACSA) and higher depression levels among German ALS patients. Longer time since diagnosis predicted lower depression and (in male subjects) higher quality of life.

Conclusions

ALS patients assess their quality of life and mood lower than healthy individuals within the studied countries. The relationships between clinical and demographic factors are moderated by country of provenance, which bears implications for the design and interpretation of scientific and clinical studies, which should reflect the complexity and heterogeneity of mechanisms determining QoL.

Background

After the Coronavirus pandemic, many educational routines were stopped for the safety of medical staff. To achieve educational goals, we have implemented new policies in our hospitals. In this study, we aimed to evaluate the effect of such strategies.

Method

This survey-based study uses questionnaires to assess newly implemented educational strategies. We surveyed 107 medical staff of the orthopedic department of Tehran University of Medical Sciences, including faculty members, residents, and students. The survey contained three series of questionnaires for these groups.

Results

The maximum satisfaction for all three groups was observed in the platform and facilities for using e-classes, and the cost- and time-saving capabilities (Respectively, faculty members (FM): 81.8%, residents (R): 95.2%, students/interns (S/I): 87.0%; FM: 90.9%, R: 88.1%, S/I: 81.5%). The new policies have been shown to reduce the stress level of most trainees, increase the quality of knowledge-based education, increase the opportunity for reexamining educational content, expand discussion and research opportunities, and improve work conditions. There was a broad acceptance of the virtual journal clubs and morning reports. However, there were discrepancies between residents and faculty members on issues such as the evaluation of trainees, the new educational curriculum, and flexible shift schedules. Our strategies failed to improve skill-based education and patient treatment status. Most participants indicated that e-learning should be used with face-to-face training post-pandemic (FM: 81.8%, R: 83.3%, S/I: 75.9%).

Conclusion

Our efforts to optimize the educational system during this crisis have generally improved trainees’ work conditions and educational experience. Most participants believed that e-learning and virtual methods should be used alongside traditional training as a complementary component after the pandemic.
Virtual versus paper-based PBL in a pulmonology course for medical undergraduates

Published: June 2023

Background

Problem-based learning (PBL) remains a valid and effective tool for small-group medical education. Using Virtual patients (VP) case simulation in PBL is a recognizable educational method that has successfully prepared students to focus learning on core information that uses realistic patient-based cases relating to everyday clinical scenarios. Using other modalities as the virtual patient in PBL instead of the paper-based methods remains debatable.

This study aimed to evaluate the effectiveness of using VP case simulation mannequin in PBL versus the PBL in paper-based cases in improving the cognitive skills by comparing the grades of a multiple-choice question test and assess its ability to reach students' satisfaction using questionnaire with Likert survey instrument.

Methods

The study was conducted on 459 fourth-year medical students studying in the pulmonology module of the internal medicine course, Faculty of Medicine, October 6 University. All students were divided into 16 PBL classes and randomly divided into groups A and B by simple manual randomization. The groups were parallel with a controlled cross-over study between paper-based and virtual patient PBL.

Results

The pre-test showed no significant difference between both, while post-test scores were significantly higher in both VP PBL cases 1 discussing COPD (6.25 ± 0.875) and case 2 discussing pneumonia (6.56 ± 1.396) compared to paper-based PBL (5.29 ± 1.166, 5.57 ± SD1.388, respectively) at p < 0.1 When students in Group A experienced PBL using VP in case 2 after paper-based PBL in case 1, their post-test score improved significantly. (from 5.26 to 6.56, p < .01). Meanwhile, there was a significant regression in the post-test score of the students in Group B when they experienced the paper-based PBL session in case 2 after using PBL using VP in case 1, (from 6.26 to 5.57, p < .01). Most of the students recommended using VP in PBL as they found VP was more engaging and inducing concentration in gathering the information needed to characterize the patient’s problem than in a classroom- paper-based cases session. They also enjoyed the teaching of the instructor and found it a suitable learning style for them.

Conclusion

Implementing virtual patients in PBL increased knowledge acquisition and understanding in medical students and was more motivating for students than paper based PBL to gather the needed information.

Published: June 2023

Background

Remote mental health consultations were swiftly implemented across mental health services during the COVID-19 pandemic. Research has begun to inform future design and delivery of telemental health services. Exploring the in-depth experiences of those involved is important to understand the complex, multi-level factors that influence the implementation of remote mental health consultations. The aim of this study was to explore stakeholder perspectives and experiences of the implementation of remote mental health consultations during the COVID-19 pandemic in Ireland.

Methods

A qualitative study was conducted whereby semi-structured, individual interviews were undertaken with mental health providers, service users, and managers (n = 19) to acquire rich information. Interviews were conducted between November 2021 and July 2022. The interview guide was informed by the Consolidated Framework for Implementation Research (CFIR). Data were analysed thematically using a deductive and inductive approach.

Results

Six themes were identified. The advantages of remote mental health consultations were described, including convenience and increased accessibility to care. Providers and managers described varying levels of success with implementation, citing complexity and incompatibility with existing workflows as barriers to adoption. Providers’ access to resources, guidance, and training were notable facilitators. Participants perceived remote mental health consultations to be satisfactory but not equivalent to in-person care in terms of quality. Views about the inferior quality of remote consultations stemmed from beliefs about the inhibited therapeutic relationship and a possible reduction in effectiveness compared to in-person care. Whilst a return to in-person services was mostly preferred, participants acknowledged a potential adjunct role for remote consultations in certain circumstances.

Conclusions

Remote mental health consultations were welcomed as a means to continue care during the COVID-19 pandemic. Their swift and necessary adoption placed pressure on providers and organisations to adapt quickly, navigating challenges and adjusting to a new way of working. This implementation created changes to workflows and dynamics that disrupted the traditional method of mental health care delivery. Further consideration of the importance of the therapeutic relationship and fostering positive provider beliefs and feelings of competence are needed to ensure satisfactory and effective implementation of remote mental health consultations going forward.
Patient satisfaction – results of cluster analysis of finnish patients
Authors: Nurmeksela Anu , Kulmala Markus , Kvist Tarja
Published: June 2023

Background

Healthcare providers must understand patients’ expectations and perceptions of the care they receive to provide high-quality care. The purpose of this study is to identify and analyse different clusters of patient satisfaction with the quality of care at Finnish acute care hospitals.

Methods

A cross-sectional design was applied. The data were collected in 2017 from three Finnish acute care hospitals with the Revised Humane Caring Scale (RHCS) as a paper questionnaire, including six background questions and six subscales. Thek-means clustering method was used to define and analyse clusters in the data. The unit of analysis was a health system encompassing inpatients and outpatients. Clusters revealed the common characteristics shared by the different groups of patients.

Results

A total of 1810 patients participated in the study. Patient satisfaction was categorised into four groups: dissatisfied (n = 58), moderately dissatisfied (n = 249), moderately satisfied (n = 608), and satisfied (n = 895). The scores for each subscale were significantly above average in the satisfied patient group. The dissatisfied and moderately dissatisfied patient groups reported scores for all six subscales that were clearly below the average value. The groups significantly differed in terms of hospital admission (p = .013) and living situation (p = .009). Patients representing the dissatisfied and moderately dissatisfied groups were acutely admitted more frequently than patients in other groups and were more likely to live alone than satisfied and moderately satisfied patients.

Conclusion

The results mostly demonstrated high levels of patient satisfaction; however, the perceptions of minority populations of dissatisfied patients should be assessed to identify shortcomings in the care provided. More attention should be paid to acutely admitted patients who are living alone and the pain and apprehension management of all patients.
