Authors: Joseph Joveeta , Karoliya Roshini , Sheba Esther , Sharma Savitri , Bagga Bhupesh , Garg Prashant
Published: August 2022

Purpose:

The aims of this study were to assess the trends in microorganisms from patients with infectious keratitis and to assess their antibiogram patterns at a tertiary eye care center in India.

Methods:

In this retrospective observational case series, microbiological records of all corneal ulcers were reviewed from 1991 to 2020 and assessed for trends in keratitis and antibiotic susceptibility using the χ2 test.

Results:

Of the total of 51,747 patients, 51.13% were culture positive. A decrease in bacteria was noted from 56% to 38%, with a parallel increase in fungal isolates from 24% to 51%. Gram-positive bacteria accounted for 70.8% of the total bacteria, a trend in rise of Streptococcus pneumoniae (31%) and a decreasing trend in prevalence of Staphylococcus epidermidis was observed over 30 years. Pseudomonas aeruginosa (55.5%) was the most prevalent gram-negative pathogen, whereas Fusarium spp. (33.1%) and Aspergillus spp. (32.4%) were the most common fungal isolates. The susceptibility of gram-positive organisms to cefazolin decreased from 95.5% to 66% (P = 0.0001), amikacin from 88% to 55% (P= 0.0001), and vancomycin from 98.9% to 90.7% (P < 0.05). A similar decrease in susceptibility was also significant for gram-negative organisms with piperacillin/tazobactam and chloramphenicol (P < 0.05). A significant trend toward increasing resistance against fluoroquinolones was also observed for ciprofloxacin (gram-positive organisms: 16% to 50%; gram-negative organisms: 11.5% to 18.7%), gatifloxacin (38% to 47%), and moxifloxacin (9.4% to 29%).

Conclusions:

The spectrum of keratitis has changed, and fungus is now the predominant etiology. An increasing trend in resistance to all antibiotics studied would affect the empiric treatment, also suggesting regular surveillance.

Authors: Burk Bradley G. , Donaldson Victoria , Jackson Cherry W. , Cates Marshall E. , Birur Badari
Published: August 2022

Purpose/Background

Antipsychotic-associated sialorrhea is a problematic adverse effect with potentially negative consequences on quality of life and medication adherence. While clozapine is the antipsychotic that is most associated with sialorrhea, there have been published reports of other second-generation antipsychotics associated with sialorrhea, including aripiprazole, olanzapine, quetiapine, and risperidone. Although drooling is mentioned within the package insert for paliperidone, to date there have been minimal published reports in which paliperidone is implicated as the offending agent.

Methods/Procedures

Here, we present a case of sialorrhea in a 56-year-old man with schizoaffective disorder who had a supratherapeutic paliperidone level after both oral and intramuscular paliperidone use.

Findings/Results

Paliperidone was ultimately cross tapered to aripiprazole, and the patient was given atropine drops and benztropine with resolution of the sialorrhea. We provide a review of the literature regarding the other available reports of paliperidone-associated sialorrhea, possible mechanisms behind pathophysiology, as well as reports from the World Health Organization and Food and Drug Administration adverse event reporting systems.

Implications/Conclusions

Clinicians should be aware of the potential for paliperidone and other nonclozapine second-generation antipsychotics to be associated with sialorrhea, especially given the increased frequency of their use for a variety of psychiatric disorders.

Authors: Zhang Wei , Sun Huiying , Gelfand Aaron , Sawatzky Richard , Pearce Alison , Anis Aslam H. , Prescott Katrina , Lee Christine
Published: August 2022

Objective

The aim of this study was to measure the association of working from home (WFH) with work productivity loss due to caregiving responsibilities or health problems during the COVID-19 pandemic.

Methods

We conducted an online survey of family/friend caregivers (n = 150 WFH/75 non-WFH) and patients (n = 95/91) who worked during the past 7 days in May and July 2020, respectively. Absenteeism and presenteeism were measured using the Valuation of Lost Productivity questionnaire.

Results

Working from home was associated with higher odds of absenteeism (odds ratio, 2.53; 95% confidence interval, 1.11 to 5.77) and presenteeism (2.79; 1.26 to 6.18) among caregivers and higher odds of presenteeism among patients (2.78; 1.13 to 6.84). However, among caregivers with absenteeism more than 0 days, WFH was significantly associated with fewer absent workdays.

Conclusions

Working from home was not associated with overall absenteeism and presenteeism in caregivers or patients. Working from home allows a more flexible and inclusive workplace without impacting productivity, although further research is needed.
A Custom Silicone Foot Orthosis for Partial Calcanectomy Fabricated Using a 3D-Printed Mold
Authors: Putra Ketut B. , Wood Heather , Wensman Jeffrey , Leonard James A. , Shih Albert
Published: August 2022

Introduction

Patients with partial foot amputations are prone to skin breakdown due to concentrated contact stress and shearing. A custom silicone foot orthosis (FO) can be used to redistribute the concentrated stress and reduce the shearing and discomfort of the skin of a patient with partial calcanectomy. This study presents a custom silicone FO, which is molded using a 3D-printed mold.

Methods

The subject's left (amputated) partial foot and right (intact) foot were scanned using a 3D scanner. A custom silicone FO was designed by modifying the models of both feet. A mold for the FO was designed using computer-aided design software and fabricated by 3D printing. Room temperature vulcanization silicone was molded to fabricate the FO. The fit of the FO was clinically evaluated by the subject walking with the FO.

Results

A custom silicone FO was fabricated using a 3D-printed mold.

Conclusions

The custom silicone FO follows the contour of the residual foot to distribute pressure away from bony prominences during standing and ambulation. 3D printing of the mold can reduce labor time and material cost while facilitating the digital record when compared with a conventional plaster casting approach.

Clinical Relevance

The 3D printing approach used to fabricate the custom silicone FO may be applied to develop custom silicone orthotic/prosthetic devices for other types of partial foot amputations.

Authors: Awad-Igbaria Yaseen , Palzur Eilam , Nasser Manal , Vieira-Baptista Pedro , Bornstein Jacob
Published: August 2022

Objective

The etiology of localized provoked vulvodynia (LPV) remains unknown, but observations suggest the involvement of the vaginal microbiota. We examined the vaginal microbiota of women with LPV and healthy controls, upon after a low-oxalate diet (LOD).

Materials and Methods

A total of 9 women diagnosed with secondary LPV and 21 healthy controls were recruited from the Galilee Medical Center in Israel and subjected to prospective evaluations of their vaginal microbiota. Total DNA was extracted from vaginal discharge samples provided before and after following LOD for 3 weeks and was then subjected to 16S sequencing. Data obtained were then used to evaluate α and β diversity, identify differentially abundant bacterial taxa in LPV, and determine their impact on the metabolism.

Results

These evaluations revealed decreased diversity in the vaginal microbiota of women with LPV and identified the Ochrobactrum genus and Pseudomonadaceae family as indicators for LPV. In addition, we identified 23 differentially expressed bacterial metabolic pathways between the LPV and control samples and revealed that LOD could induce changes in the β diversity of LPV vaginal microbiomes, which was further supported by some degree of pain reduction in patients.

Conclusions

Localized provoked vulvodynia and LOD were associated with shifts in the vaginal microbiota. However, the impact of these changes on the development of LPV requires additional studies with a larger cohort.
Mastoidectomy Training: Is Anatomical Variation Needed? A Randomized, Controlled Trial on Performance and Skills Transfer From Virtual Reality to a Three-Dimensional Printed Model
Authors: Arnesen Karoline Abildsø , Frithioff Andreas , Sørensen Mads Sølvsten , Andersen Steven Arild Wuyts , Frendø Martin
Published: August 2022

Objective

Virtual reality (VR) simulation-based training effectively improves novices' mastoidectomy skills. Unfortunately, learning plateaus at an insufficient level and knowledge on optimizing mastoidectomy training to overcome this plateau is needed. In this study, we aim to investigate how training on anatomically different temporal bone cases affects learning, including the effect on retention and transfer of skills.

Study Design

Randomized controlled trial of an educational intervention.

Setting

The Simulation Center at Copenhagen Academy for Medical Education and Simulation.

Participants

Twenty-four medical students from the University of Copenhagen.

Intervention

Participants were randomized to practice mastoidectomy on either 12 anatomically varying (intervention group) or 12 identical (control group) cases in a VR simulator. At the end of training and again ~ 3 weeks after training (retention), learners were tested on a new VR patient case and a three-dimensional printed model.

Main Outcome Measure

Mastoidectomy performance evaluated by blinded expert raters using a 26-item modified Welling Scale.

Results

The intervention and control groups' performance results were comparable at the end of training. Likewise, retention and transfer performances were similar between groups. The overall mean score at the end of training corresponded to approximately 70% of the possible maximum score.

Conclusions

Simulation-based training using anatomical variation was equivalent to training on a single case with respect to acquisition, retention, and transfer of mastoidectomy skills. This suggests that efforts to expose novices to variation during initial training are unnecessary as this variation has limited effect, and—conversely—that educators can expose novices to naturally different anatomical variations without worry of hindered learning.
Update on Staphylococcus aureus bacteraemia
Authors: Tabah Alexis , Laupland Kevin B.
Published: August 2022

Purpose of review

To review recently published evidence relevant to Staphylococcus aureus bacteremia (SAB).

Recent findings

Staphylococcus aureus is the most common pathogen causing co-infections and superinfections in patients with COVID-19. Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia ratios have sharply risen during the pandemic. SAB mortality is 18% at 1 month and 27% at 3 months but has gradually decreased over the last 30 years. Recurrences and reinfections are common (9%). Standardised items to define complicated SAB, and a new cut-off defining persisting bacteremia after 2 days with positive blood cultures have been proposed. Multiple antibiotic combinations have been trialled including vancomycin or daptomycin with β-lactams, fosfomycin, or clindamycin, without significant results. In the recently published guidelines, vancomycin remains the first line of treatment for MRSA bacteremia. For the management of methicillin-susceptible Staphylococcus aureus, cefazolin less frequently causes acute kidney injury than flucloxacillin, and when susceptibility is demonstrated, de-escalation to penicillin G is suggested.

Our review confirms that Staphylococcus aureus represents a special aetiology among all causes of bloodstream infections. Pending results of platform and larger trials, its distinct epidemiology and determinants mandate careful integration of clinical variables and best available evidence to optimize patient outcomes.
Prevalence of stress among nursing students: A protocol for systematic review and meta-analysis
Authors: Zheng Yan-xue , Jiao Jia-Ru , Hao Wen-Nv
Published: August 2022

Objective:

Our main purpose is to evaluate the prevalence of stress among nursing students systematically.

Methods:

Adhering to the preferred reporting items for Systematic Reviews and Meta-analyses guidelines, we carefully searched ten databases, including PubMed, Cochrane, Web of Science, Scopus, ScienceDirect, SpringerLink, EMBASE, CNKI, Wanfang, and China Biomedical Literature Service System, to collect cross-sectional studies on nursing students. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies.

Results:

From 1397 studies, 27 cross-sectional studies were included, including 7116 subjects. Meta-analysis showed that the prevalence of low-level stress was 0.24% [95% CI (0.24% to 0.25%)], the prevalence of middle level stress was 0.35% [95% CI (0.35% to 0.35%)], and the prevalence of high-level stress was 0.10% [95% CI (0.10% to 0.10%)]. The results of subgroup analysis showed that stress levels are different in different genders, diagnostic criteria for stress, years of publication, and regions.

Conclusions:

This review identified the stress levels of nursing interns, which were mainly moderate. This result makes nursing administrators and nursing educators pay more attention to the mental health problems of nursing interns, which can actively take measures to promote the physical and mental health of nursing students, improve the quality of nursing students’ practice, and further promote the development of the nursing profession.

Authors: Asghar Muhammad Sohaib , Ahsan Muhammad Nadeem , Mal Pooran , Tahir Muhammad Junaid , Yasmin Farah , Abbasher Hussien Mohamed Ahmed Khabab
Published: August 2022

Background and Objectives:

Patients of end-stage renal disease are prone to have a very low quality of life (QoL). Variety of factors influence the QoL among sufferers of chronic kidney disease comprising of type of dialysis, sufficiency/adequacy of dialysis, and associated burden of disease. We conducted this study amidst the pandemic to determine the associated factors for poor QoL in hemodialysis patients during the ongoing pandemic.

Patients and Methods:

This cross-sectional study was conducted in a hemodialysis unit of a tertiary care hospital. A total of 118 participants responded to the validated questionnaire of Quality of Life Index-dialysis version-III (QLI). Higher scores signify good QoL, total scores are further categorized into subgroups desirable, relatively desirable and undesirable.

Results:

The mean age of the participants was 57.36 ± 10.03 years and mean body mass index of 26.73 ± 5.54 kg/m2. The mean total QoL of the study population was found quite low (12.99 ± 5.89). Majority of respondents fell in undesirable category of QoL (49.2%). Total QoL (P = 0.004) and subscale health/functioning (P = 0.003) were significantly lower in females. All the subscales along with total QoL scores were found lower in twice-weekly dialyzed patients (P < 0.001). Marital status (P = 0.049) and twice-weekly dialysis (P < 0.001) were found significant with undesirable QoL. On multivariate analysis, significant determinants of undesirable QoL were twice-weekly dialysis (P = 0.001), catheter access (P = 0.034), phosphate (P = 0.005) and uric acid (P = 0.006).

Conclusion:

Inadequate dialysis due to lesser frequency per week leading to poorly cleared toxic substances were most significant contributors of poor QoL in our study.
Dental anomalies in cleft lip and palate: A case–control comparison of total and outside the cleft prevalence

Published: August 2022

This study’s objective was to compare the total and outside the cleft prevalence of dental anomalies (DA) between patients with cleft lip and palate (CLP) and a control group. This retrospective cross-sectional study was done under a case–control design. The case group consisted of 192 non-syndromic patients with complete CLP, while the control group included 411 patients. All subjects had orthopantomography, intra, and extraoral photographs. The prevalence of dental agenesis, supernumerary teeth, impacted teeth, dental transposition, and microdontia were compared using a chi-squared test (P < .05). Next, a second test was made, but only the anomalies outside the cleft were considered for this study. Total prevalence was 89.1% for cases, and 20.9% for controls (P < .01). The prevalence of each DA was significantly higher for the case group. In the analysis of DAs outside the cleft, the total prevalence was still significantly associated (P < .01); however, only dental agenesis was statistically significant (P < .01). Further analysis found that a high rate of upper premolar absence (P < .01) could explain this event. Patients with CLP have a higher prevalence of DAs compared to controls. After considering only the DAs outside the cleft, the total prevalence remains significantly higher. However, this phenomenon is explained mainly by the elevated prevalence of upper premolars’ agenesis. This study’s results suggest that environmental factors are behind the high prevalence of DAs in subjects with CLP.
Profile of serious angioedema requiring an urgent advice from a national reference call center
Authors: Simon Nicolas , Bocquet Alexis , Boccon-Gibod Isabelle , Bouillet Laurence
Published: August 2022

Angioedema (AE) is a reason for emergency care when it is severe. Care is difficult when the diagnostic is not known before the attack: mast cell (MC) or bradykinin (BK) mediated. One is very common but often benign, the other rare but potentially fatal. The French national reference center of angioedema (CREAK) provides emergency physicians with a hotline and a guideline to help them manage their patients. This study aimed to describe the clinical features of AE episodes prompting a call on the CREAK hotline and classify patients depending on the suspected cause of the AE. This is a retrospective study between March and August 2019. Each physician calling on the CREAK hotline was asked to fill a clinical description form for the AE emergency. Known patients of CREAK was excluded. Eighty four patients were included. Forty one (48.8%) in the angiotensin converting enzyme inhibitors induced acquired angioedema (ACEi-AAE), 39 (46.4%) in the mast cell induced angioedema, and 4 (4.8%) in the Bradykinin mediated angioedema. The mast cell induced angioedema patients have more history of hives (29.3%) than ACEi-AAE (2.4%, P = .0004). ACEi-AAE mainly affected the tongue (58.5% vs 25.6%, P = .003) and larynx (29.3% vs 13%, P = .001). In 65.5% of cases, the etiological diagnosis was not mentioned by the appellant, but made by the hotline. In 31% of cases, the hotline suggested the administration of a specific treatment not previously provided by the caller. All the doctors who called the hotline appreciate this tele-expertise especially in case of ACEi-AAE presumptions. In addition to providing rapid AE expertise, this service also allows to educate physicians in the management of AE irrespective of its origin.
Comparison of negative pressure wound therapy and moist wound care in patients with diabetic foot ulcers: A protocol for systematic review and meta-analysis of randomized controlled trials
Authors: Wang Nan , Li Shuang-Shuang , Liu Ya-Ping , Peng Ying-Ying , Wang Peng-Fei
Published: August 2022

Background:

This study conducted a meta-analysis to compare the effectiveness and safety of the negative pressure wound therapy (NPWT) with the moist wound care (MWC) in the treatment of diabetic foot ulcers (DFUs).

Methods:

The PubMed, EMBASE, and CENTRAL were searched by 2 of the authors, to identify randomized controlled trials comparing the clinical outcomes of patients treated with NPWT versus MWC for DFUs. Meta-analyses were performed for several outcomes, including wound healing results, amputation or resection incidence, and risk of adverse events, utilizing the “meta” package of R language version 4.0.3.

Results:

A total of 10 trials (619 patients in NPWT group and 625 in MWC group) and 8 trials were included for the qualitative and quantitative syntheses, respectively. As a result, significantly lower risk of non-closure of the wound (risk ratio [RR] = 0.74, 95% confidence interval [CI]: 0.63–0.87; P = .001), lower average wound area (standard mean difference = −0.80, 95% CI: −1.54 to −0.06; P = .034), more wound area decrease (standard mean difference = 0.81, 95% CI: 0.36–1.26; P = .001), increased appearance rate of granulation tissue (RR = 1.61, 95% CI: 1.07–2.41; P-0.021), and lower risk of amputation or resection (RR = 0.70, 95% CI: 0.50–0.99; P = .045), were demonstrated for the NPWT group when compared to MWC group. However, no statistically significant difference was found for the disappearance rate of wound discharge at 8 weeks, the rate of blood culture positivity, VAS-pain score, and the overall frequency of adverse events between the 2 treatment groups (P = .05).

Conclusion:

NPWT could accelerate process of the wound healing, and decrease the risk of post-treatment amputation or resection, without any additional frequency of adverse events, when compared with MWC, in patients with DFUs.
The analysis of tumor-infiltrating immune cell and ceRNA networks in laryngeal squamous cell carcinoma
Authors: Li Dan , Dong Kaifeng , Su Jing , Xue Haitao , Tian Junhai , Wu Yongfeng , Wang Jingtian
Published: August 2022

Background:

Laryngeal squamous cell carcinoma (LSCC) is one of the most common forms of head and neck cancers. However, few studies have focused on the correlation between competing endogenous RNA (ceRNAs) and immune cells in LSCC.

Methods:

RNAseq expression of LSCC and adjacent tissues were downloaded from The Cancer Genome Atlas to establish a ceRNA network. The key gene in ceRNA was screened by the cox regression analysis to establish a prognostic risk assessment model. The CIBERSORT algorithm was then used to screen important tumor-infiltrating cells related to LSCC. Finally, co-expression analysis was applied to explore the relationship between key genes in the ceRNA network and tumor-infiltrating cells. The external datasets were used to validate critical biomarkers.

Results:

We constructed a prognostic risk assessment model of key genes in the ceRNA network. As it turned out, Kaplan–Meier survival analysis showed significant differences in overall survival rates between high-risk and low-risk groups (P < .001). The survival rate of the high-risk group was drastically lower than that of the low-risk group, and the AUC of 1 year, 3 years, and 5 years were all above 0.7. In addition, some immune infiltrating cells were also found to be related to LSCC. In the co-expression analysis, there is a negative correlation between plasma cells and TUBB3 (r = −0.33, P = .0013). External dataset validation also supports this result.

Conclusion:

In this study, we found that some key genes (SLC35C1, CLDN23, HOXB7, STC2, TMEM158, TNFRSF4, TUBB3) and immune cells (plasma cells) may correspond to the prognosis of LSCC.
Development of a SETD2-related immune prognostic signature in clear cell renal cell carcinoma
Authors: Wang Xingyuan , Xia Zhinan , Li Zhiyuan , Zhang Cheng
Published: August 2022

Background:

Renal cell carcinoma (RCC) is a malignant tumor of urinary system, and clear cell RCC (ccRCC) is the major pathological subtype. A high-frequency mutation in SETD2 gene is related to the occurrence, development, and poor prognosis of RCC.

Objective:

The research of immune-related genes (IRGs) is important to the success of immunotherapy in RCC. The aim of this study was to develop SETD2-related immune prognostic signature (IPS) potentially useful in the prognosis prediction of ccRCC.

Methods:

The expression profile, mutation profile, and clinical data related to ccRCC were obtained from the TCGA (Cancer Genome Atlas) and cBioPortal databases. The data of IRGs were downloaded from the ImmPort database.

Results:

An IPS with 5 genes (PDIA2, PAEP, AMELX, GREM2, and INHA) was constructed by analyzing the correlation between prognosis data and IRGs associated with ccRCC patients with wild type and mutant SETD2 genes. The clinical utility of the IPS and its relationship with immune microenvironment were also studied.

Conclusions:

According to the results of this study, the IPS can be a promising biomarker of ccRCC to guide its prognosis and treatment.
A novel ferroptosis-related long noncoding RNA signature for relapse free survival prediction in patients with breast cancer
Authors: Wang Yuzhi , Xu Yunfei , Zhang Yi
Published: August 2022

Ferroptosis is the process of cell death dependent on iron. Growing evidence suggests that ferroptosis plays vital roles in the biological process of many cancers. However, just a small number of ferroptosis-related lncRNAs have been explored in depth.

Ferroptosis-related lncRNAs in breast cancer (BC) were identified by co-expression analysis based on The Cancer Genome Atlas database (TCGA). The whole set was divided into a training set and a test set with a 1:1 ratio. Univariate Cox regression and LASSO analyses were performed to establish a signature in the 3 sets. Kaplan-Meier analysis and receiver operating characteristic (ROC) for the 3 sets validated the effectiveness and robustness of the signature. Besides, we also explore the relationship between this and clinical characteristics, immune cell infiltration and tumor microenvironment. Meanwhile, the nomogram was drawn by screening indicators of independent recurrent prediction. Finally, we evaluated the relationships between the signature and tumor microenvironment.

We identified 391 ferroptosis-related lncRNAs and constructed a 5 lncRNAs-based signature in the training, test, and whole sets, stratifying patients into high-risk and low-risk groups. According to survival analysis, patients in the high-risk groups had worse relapse free survival (RFS) compared to the low risk-groups. The ROC curves indicated that the recurrent signature had a promising predictive capability for BC patients. Moreover, an independent factors-based nomogram model could offer the quantitative prediction and net benefit for the recurrence of BC patients. Finally, the microenvironment, including tumor mutational burden (TMB), immune cell functions and immune checkpoints, showed big differences between the 2 groups.

The 5 ferroptosis-related lncRNAs and their signature might be novel promising biomarkers and immunotherapy targets for patients with BC.
Effects of a cognitive rehabilitation program based on mnemonic skills and memory compensatory strategies for older adults: A pilot study
Authors: Kim Hyerim , Lee Jimin , Man Chang Sung , Kim Byung-Soo
Published: August 2022

Background:

With the aging of the population, the number of people with age-related memory complaints has also increased. The purpose of this study was to develop a cognitive rehabilitation program based on mnemonic skills and memory compensatory strategies (CRM) and to investigate the effects of CRM in community-dwelling older adults without dementia.

Methods:

This study was an open-label, single-arm, pilot study. We developed a CRM program comprising 8 weekly sessions. The study participants consisted of older adults with normal cognitive function and mild cognitive impairment (MCI). They were recruited from eight dementia counseling centers and one senior welfare center. To assess the effects of CRM, we administered the following tests at baseline and after completion of the program: Subjective Memory Complaints Questionnaire, the Short form of Geriatric Depression Scale, the Euro Quality of life–5 Dimension, and the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Assessment Battery.

Results:

Thirty-two participants completed the study. Among older adults with normal cognitive function, CRM showed significant improvement in verbal memory function. Among the older adults with MCI, CRM showed significant improvements in language ability, verbal recognition memory, nonverbal memory, attention, and processing speed.

Conclusion:

CRM improved cognitive function in two distinct populations, older adults with normal cognitive function and older adults with MCI. Additionally, our preliminary findings suggest that older adults with MCI show cognitive improvement in both the trained and non-trained cognitive domains.
Comprehensive metabolomics study on the pathogenesis of anaplastic astrocytoma via UPLC-Q/TOF-MS
Authors: Du Chao , Huang Zhehao , Wei Bo , Li Miao
Published: August 2022

Anaplastic astrocytoma (AA) is a malignant carcinoma whose pathogenesis remains to be fully elucidated. System biology techniques have been widely used to clarify the mechanism of diseases from a systematic perspective.

The present study aimed to explore the pathogenesis and novel potential biomarkers for the diagnosis of AA according to metabolic differences. Patients with AA (n = 12) and healthy controls (n = 15) were recruited. Serum was assayed with untargeted ultraperformance liquid chromatography-quadrupole/time-of-flight-mass spectrometry (UPLC-Q/TOF-MS) metabolomic techniques. The data were further evaluated using multivariate analysis and bioinformatic methods based on the KEGG database to determine the distinct metabolites and perturbed pathways.

Principal component analysis and orthogonal projections to latent structures-discriminant analysis (OPLS-DA) identified the significance of the distinct metabolic pattern between patients with AA and healthy controls (P < .001) in both ESI modes. Permutation testing confirmed the validity of the OPLS-DA model (permutation = 200, Q2 < 0.5). In total, 24 differentiated metabolites and 5 metabolic pathways, including sphingolipid, glycerophospholipid, caffeine, linoleic acid, and porphyrin metabolism, were identified based on the OPLS-DA model. 3-Methylxanthine, sphinganine, LysoPC(18:1), and lactosylceramide were recognized as potential biomarkers with excellent sensitivity and specificity (area under the curve > 98%).

These findings indicate that the perturbed metabolic pattern related to immune regulation and cellular signal transduction is associated with the pathogenesis of AA. 3-Methylxanthine, sphinganine, LysoPC(18:1), and lactosylceramide could be used as biomarkers of AA in future clinical practice. This study provides a therapeutic basis for further studies on the mechanism and precise clinical diagnosis of AA.
Patient-reported outcomes measures (PROMs) and patient-reported experience measures (PREMs) of COVID-19 telerehabilitation: Prospective pilot program

Published: August 2022

Telemedicine is proving to be a useful tool in the telemonitoring of respiratory patients and telerehabilitation programs. The use of telemedicine has been proposed by the main medical societies because of the limited resources and the healthcare workers infection risk in the Coronavirus Disease 2019 (COVID-19) pandemic.

The aim of this pilot program is to evaluate the feasibility of COVID-19 telerehabilitation program from the hospital to the home with clinical, functional and patient satisfaction outcomes. Rehabilitation was initiated in the hospital by a physiotherapist and complemented by “Estoi” (a mobile application), which was continued at home with telemonitoring and messaging with the medical team. Patients’ habitual use of smartphones was not queried for inclusion.

Sixteen patients were consecutively enrolled, 47% women with a mean age of 63 years old. 50% of patients completed ≥15 rehabilitation sessions. In total, 88% of patients referred that the mobile application incentive them to do more physical therapy, and 63% would choose telerehabilitation instead of center-based rehabilitation for new rehabilitation programs. Patient satisfaction (0–10) for the mobile application was 8.4 and 8.9 for the telerehabilitation program.

Beginning telerehabilitation in the hospital could increase the efficacy and efficiency of physical therapy, which is safe for patients and healthcare workers. Following at home, this telerehabilitation program seems to encourage and empower patients who have reported high satisfaction. Further randomized studies with larger numbers of patients and multicenter studies are required to evaluate these results.

Although the practice of using rapid-acting subcutaneous insulin for the management of mild-to-moderate diabetic ketoacidosis is becoming increasingly popular, the continuous insulin infusion remains widely utilized, and its real-world applicability and safety on a medical surgical unit (Med Surg) and observation level of care are unclear. We assessed whether a continuous insulin infusion protocol for mild-to-moderate diabetic ketoacidosis on Med Surg/observation level of care over a 6.5-year period was associated with adverse outcomes.

A retrospective cohort study of adults hospitalized with mild-to-moderate diabetic ketoacidosis was conducted at 2 community hospitals in Northern California, USA, from January 2014 to May 2020. Demographic and clinical variables were collected using an electronic health record. Admission to Med Surg/observation was compared to intensive care unit admission for the outcomes of 30-day readmission, presence of hypoglycemia, rate of hypoglycemic episodes, in-hospital and 30-day mortality, and length of stay using bivariate analysis.

Among 227 hospital encounters (mean age 41 years, 52.9% women, 79.3% type 1 diabetes, 97.4% utilization of continuous insulin infusion), 19.4% were readmitted within 30 days, and 20.7% developed hypoglycemia. For Med Surg/observation encounters compared to the intensive care unit, there were no statistically significant differences in the risk of readmission (RR 1.48, 95% CI, 0.86–2.52), hypoglycemia (RR 1.17, 95% CI, 0.70–1.95), or increased length of stay (RR 0.71, 95% CI, 0.55–1.02); there was a lower risk of hypoglycemic events during hospitalization (RR 0.69, 95% CI, 0.54–0.96).

Continuous insulin infusion utilization may be a safe option for treatment of mild-to-moderate diabetic ketoacidosis on Med Surg/observation level of care. Further investigation is needed.

To evaluate the efficacy and safety of a gonadotropin-releasing hormone (GnRH) agonist for treating large-sized submucosal leiomyoma before hysteroscopic myomectomy.

The data were retrospectively collected from patients who underwent a hysteroscopic myomectomy for a submucosal leiomyoma >3.5 cm in size from January 2009 to December 2018. The patients were divided into the GnRH group and the control group according to whether they were pretreated before surgery.

A total of 61 patients were included in the study, 31 in the GnRH agonist group and 30 in the control group. At diagnosis, the maximum leiomyoma diameter was similar between the 2 groups (4.67 ± 0.6 cm in the GnRH agonist group vs 3.82 ± 0.6 cm in the control group, P = .061). After pretreatment with the GnRH agonist, the maximum diameter was significantly smaller in the GnRH agonist group compared to the control group (3.82 ± 0.6 vs 4.33 ± 0.8 cm, respectively, P = .004). The leiomyoma volume in the GnRH agonist group decreased by 55.6%, from 41.68 ± 15.7 to 23.19 ± 10.4 cm3, which led to significant differences in leiomyoma volume between the 2 groups (23.19 ± 10.4 cm3 in the GnRH agonist group vs 33.22 ± 24.7 cm3 in the control group, P = .042). The GnRH agonist group showed a shorter operation time (37.7 vs 43.9 minutes, P = .040) and less uterine distention media was used (6800 vs 9373.3 mL, P = .037) compared to the control group. Postoperative complications such as estimated blood loss, remnant leiomyoma, and recurrence were similar between the 2 groups.

Treatment with a GnRH agonist before hysteroscopic myomectomy for large submucosal leiomyoma might decrease the volume of the leiomyoma, reduce operation time, and the amount of uterine-distension media used without surgical complications.

Published: August 2022

pain following minimally invasive repair of pectus excavatum (MIRPE) is a critical concern that leads to a prolonged hospital stay and high doses of opiates administered to the patients. This study aimed to evaluate the efficacy of intraoperative cryoanalgesia (cryoablation of the intercostal nerves) during MIRPE. We retrospectively analyzed the data of 64 patients who underwent MIRPE and received cryoanalgesia or epidural analgesia between January 2019 and January 2021. The oral morphine milligram equivalent (MME) was used to calculate the dosage of opioid agents. The median age was 15 years (range, 4–33 years). The median postoperative hospital stay was 4 days (range, 2–6 days), with a median oral MME consumption of 45 mg (ranging from 0 to 1360 mg). Cryoanalgesia was performed in 38 patients, and epidural analgesia was administered to the remaining 26 patients. The cryoanalgesia group had a significantly lesser pain score, shorter postoperative hospital stay and lower oral MME consumption than the epidural analgesia group (5 vs 2; P < .001, 3 days vs 5 days; P < .001, 19 mg vs 634 mg; P < .001). Cryoanalgesia appears to reduce postoperative hospital stay and opioid consumption compared with epidural analgesia. The outcomes of this study indicate that cryoanalgesia might be a safe and effective method for pain control following MIRPE.
Heart failure disease management program: A review
Authors: AlHabeeb Waleed
Published: August 2022

Disease management programs (DMPs) have shown great potential for optimizing care of chronically ill patients, thereby improving health outcomes and patient satisfaction. This had led to an overall reduction in healthcare costs. Longer life expectancy has led to increased utilization of healthcare facilities, which may lead to a rise in costs. DMPs are an effective means of improving care and compliance and ultimately curbing inappropriate resource utilization. The present study reviews different definitions proposed for disease management, its components, the evidence behind it, and the conditions for success. It also examines heart failure management as an example of a DMP, exploring the complexity surrounding implementation of guideline-based approaches in patient care. A literature search on DMPs was conducted using PubMed, MEDLINE, and Google Scholar, including heart failure management programs from articles published from 2000 to 2020. This reviewed emphasized on the management of important biomarkers and cardiovascular indicators such as glycemic levels, urine output to improve efficacy of disease management programme during patient treatment.

The review concluded that diseases like heart failure can be combat by improving the quality of care for patients and reducing the burden on the public healthcare system. Moreover, DMPs have proved to be an effective way of improving care and compliance with treatment.

Very few studies have been done in HER2 positive patients without complete pathological response (pCR) after combined neoadjuvant chemo- and HER2-target therapy to investigate changes in intrinsic subtype, risk of recurrence (ROR) score, and immunity status before and after treatment.

Patients with nonmetastatic HER2-positive breast cancer failed to achieve pCR after neoadjuvant chemotherapy plus trastuzumab were included in current study. We examined the distribution of PAM50 subtypes, ROR score and immunity score in 25 paired baseline and surgical samples. The Miller–Payne grading system was used to evaluate the efficacy of the neoadjuvant therapy. It was observed that the distribution of intrinsic subtype, ROR category and immunity subgroup varied according to hormone receptor (HR) status. HER2-enriched and basal-like subtypes, median-high ROR categories and immunity-weak subgroup were dominant in baseline tumors. Compared to baseline samples, conversion of intrinsic subtype, ROR categories and immunity subgroups were found in 15 (60.0%), 13(52.0%), and 11(44.0%) surgical samples, respectively. The PAM50 subtype, ROR category, and immunity subgroup were concordant between baseline and surgical samples where nonluminal subtypes, median-high ROR categories and i-weak subgroup were still common.

In conclusion, the HER2-positive breast cancer is highly heterogeneous with a distribution of 72-gene expression varying according to HR co-expression. The dynamics of the 72-gene expression pre- and posttreatment may become novel biomarker for guiding adjuvant therapy and hence warrant further investigation.

Background:

This study retrospectively investigated the effects of target nursing care (TNC) on anxiety and depression in patients with gallbladder cancer (GBC) during the perioperative period.

Methods:

This retrospective study analyzed the data of 80 patients with GBC during perioperative period. These records were divided into an intervention group (n = 40) or a control group (n = 40). All 80 patient records in both groups were administered routine nursing care (RNC). The patients in the intervention group also underwent TNC. The primary outcomes were depression (measured using the Hamilton Depression Scale, HAMD) and anxiety (assessed using the Hamilton Anxiety Scale, HAMA). The secondary outcomes were quality of life (assessed using the 36-Item Short Form Health Survey, SF-36) and adverse events. We collected and analyzed the outcome data before and after treatment.

Results:

After treatment, patients in the intervention group showed more promising effects on depression (HAMD, P < .01) and anxiety (HAMA, P < .01) than those in the control group did. However, there were no significant differences in the quality of life before and after treatment. No TNC- or RNC-associated adverse events were reported in patient records.

Conclusion:

This study found that TNC was more effective than RNC in relieving depression and anxiety. Future studies should be conducted to validate the present findings.

Since the emergency approval of several therapeutic coronavirus disease 2019 (COVID-19) vaccines in the United States, >500 million doses have been administered. However, there have been disparities in vaccine acceptability and uptake. We examined demographic, human immunodeficiency virus (HIV) disease, and psychosocial factors associated with COVID-19 vaccine acceptability in older adults (≥50 years) living with HIV in the Coachella Valley, California.

Participants completed a 1-time anonymous online questionnaire assessing their demographic (i.e., age, race, education, etc), HIV disease (i.e., viral suppression, years living with HIV, acquired immunodeficiency syndrome diagnosis), psychosocial (i.e., HIV-related stigma, personal mastery, depression, etc) characteristics, and COVID-19 vaccine acceptability. Respondents were offered an electronic $20 United States dollar (USD) gift card for survey completion. Descriptive, univariable, and multivariable tests were conducted to analyze the data.

Between September 2020 and February 2021, 114 surveys were completed. Eighty-six (75%) agreed/strongly agreed with the COVID-19 vaccine acceptability statement that they saw no problem with receiving a COVID-19 vaccine if one became available. Among those who agreed/strongly agreed, the mean age was 62.2 years (standard deviation = 7.20); 86% self-identified as White; 95% male; 91% with more than high school education; and 31% with annual income <$20,000 USD. Among respondents who disagreed/strongly disagreed, the mean age was 59.9 years (standard deviation = 4.85); 50% self-identified as White; 50% male; 64% with more than high school education; and 4% with annual income <$20,000 USD. In the univariable analyses, those who disagreed/strongly disagreed with the COVID-19 vaccine acceptability statement were significantly more likely to be living with HIV for fewer years, experiencing higher levels of HIV-related stigma and depression, and with lower levels of personal mastery. In the multivariable logistic regression model, self-identification as female vs male and unemployed vs employed was significantly associated with decreased COVID-19 vaccine acceptability (odds ratio = 0.09, 95% confidence interval: 0.01–0.71 and odds ratio = 0.08, 95% confidence interval: 0.01–0.70 respectively), adjusting for ethnicity, marital status, education, disability, years living with HIV, HIV-related stigma, and depression.

Additional studies are needed to understand vaccine-related decision-making among older adults living with HIV. Programmatic efforts may also be necessary to disseminate accurate information/resources about COVID-19 vaccines to those with more recent HIV diagnoses, experiencing HIV-related stigma and depression, with lower levels of personal mastery, and facing socioeconomic disparities.
