Abstract
Background
Immunosuppressive therapies have become a cornerstone of the management of severe COVID-19. The impact of these therapies on secondary infections and antimicrobial prescribing remains unclear. We sought to assess antimicrobial use and the incidence of bacterial and fungal infections in patients with severe COVID-19, and to explore their associations with receipt of immunosuppressive therapies.

Methods
Our retrospective cohort study included 715 hospitalised, adult patients with severe COVID-19 admitted to St George’s Hospital, London, UK, during the first UK pandemic wave (1st March–10th June 2020). Co-infections (occurring within 48 h of admission) and secondary infections (≥ 48 h) were defined as a positive microbiological culture with supporting clinical, radiological or laboratory data to suggest true infection. Cox regression models with time-dependent covariates were used to explore the association between immunosuppressant use and secondary infection.

Results
Microbiologically confirmed co-infection occurred in 4.2% (n = 30) and secondary infection in 9.3% (n = 66) of the cohort (n = 715) and were associated with in-hospital mortality (48% vs 35%, OR 1.8, 95%CI 1.1–2.7, p = 0.01). Respiratory (n = 41, 39%) and bloodstream infections (n = 38, 36%) predominated, with primarily Gram-negative pathogens. 606 (84.7%) patients received an antimicrobial, amounting to 742 days of therapy per 1000 patient-days (DOTs). In multivariable models, receipt of high-dose steroids (≥ 30 mg prednisolone or equivalent) or tocilizumab was significantly associated with increased antimicrobial consumption (+ 5.5 DOTs, 95%CI 3.4–7.7 days) but not secondary infection (HR 0.56, 95%CI 0.26–1.18).

Conclusions
Bacterial and fungal infections in severe COVID-19 were uncommon. Receipt of steroids or tocilizumab was independently associated with antimicrobial consumption despite its lack of association with secondary infection. These findings should galvanise efforts to promote antimicrobial stewardship in patients with COVID-19.

Abstract
Introduction
Multiple sclerosis (MS) is the most prevalent disease of the central nervous system that affects the behavioral characteristics and lifestyle of patients. This study aimed to determine the social stigma and its relationship with quality of life in people with MS referring to the Jahrom MS Association.

Method
This cross-sectional study was conducted on MS patients who are members of the MS Association of Jahrom City in Fars province, southern Iran in 2022. The samples were selected by census method. The number of participants remain 223 people. The data was collected using a standard two-part demographic and Multiple Sclerosis Quality of Life-54 (MSQOL-54) questionnaire and a researcher-made 20-question Social stigma questionnaire which validity and reliability were measured. Data analysis was done in a descriptive way (frequency, percentage, mean and standard deviation), univariate regression and multivariable linear regression. Data analysis was done using SPSS version 17 and at a significance level of less than 0.05.

Result
Based on univariate regression, marriage [B = 0.2, p-value = 0.004], physical health [B = 0.4, p-value < 0.001], emotional well-being [B = 0.4, p-value = 0.001], cognitive functioning [B = 0.4, p-value < 0.001], health distress [B = 0.5, p-value < 0.001] had a positive and significant relationship with patients’ quality of life. Duration of disease [B=-0.2, p-value < 0.001], physical role limitations [B=-0.4, p-value < 0.001], emotional role limitations [B=-0.5, p-value < 0.001], pain [B=-0.4, p-value < 0.001], energy [B=-0.3, p-value = 0.02], health perception [B=-0.3, p-value = 0.001], social functioning [B=-0.4, p-value < 0.001], sexual function [B=-0.3, p-value < 0.001], change in health [B=-0.3, p-value < 0.001], sexual function satisfaction [B=-0.3, p-value < 0.001] and social stigma [B=-0.3, p-value < 0.001] had a negative and significant relationship with patients’ quality of life (p < 0.05).

Conclusion
The study has emphasized the relationship between the extent and severity of symptoms and disorders with the quality of life of people with MS. The results of the study showed factors such as marriage, physical health and health distress have a positive relationship and factors like duration of disease, physical role limitations, and social stigma have a negative relationship with the quality of life of people with MS. The quality of life of people with MS is more influenced by mental and psychological factors than the physical limitations of these patients.
The effect of fatigue on postural control in individuals with multiple sclerosis: a systematic review
Authors: Sedaghati Parisa , Alghosi Mohammad , Hosseini Freshteh 
Published: November 2023

Abstract
Background
Fatigue is the most disabling symptom for individuals with multiple sclerosis (MS), which can significantly affect postural control (PC) by impairing the ability of the central nervous system to modulate sensory inputs and coordinate motor responses. This systematic review aimed to investigate the effect of fatigue on PC in individuals with MS..

Methods
This systematic review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline and registered in PROSPERO with ID CRD42022376262. A systematic search was performed in the Web of Science, PubMed, Scopus, and Google Scholar until January 2023, and a manual search was performed using the reference lists of included studies. Two authors independently selected the studies, extracted data, and evaluated their methodological quality using the Downs and Black checklist. The process was later discussed with a third author..

Results
Five studies were included in this review, of which consistent evidence investigating a direct relationship between fatigue and PC in individuals with MS. All the studies reported negative effects on PC. Four studies employed walking tests as their primary protocol for inducing fatigue, while one study implemented a strength testing protocol for both legs, serving as a fatigue-inducing activity.

Conclusions
The evidence suggests that individuals with MS may experience PC deficits due to fatigue. However, the present body of literature exhibits limitations regarding its quality and methodology. Gender differences, balance, fatigue task, and muscle function are essential factors that need to be considered when investigating the relationship between fatigue and PC deficits in MS. Further high-quality research is necessary to comprehend the complex interplay between MS-related fatigue and PC deficits after physical activity.

Published: November 2023

Abstract
Background
To explore the predictive value of Ellipsoid Zone (EZ) -related angle parameters for the outcome of primary macular hole surgery.

Methods
This was a retrospective study. Patients diagnosed with large macular hole (MH) (minimum diameter > 500 μm) between 2018 and 2021 were enrolled. All patients underwent 25-gauge pars plana vitrectomy, internal limiting membrane (ILM) peeling and air tamponade. Spectral-domain OCT (SD-OCT) and best corrected visual acuity (BCVA) were measured in preoperative and 2-week post-operative. Classic and angle related parameters were measured via ImageJ. Angle regularity (AR) were defined as the standard deviation of the angle parameters in vertical and horizontal direction.

Results
Seventy-six eyes were included for analysis; 24 eyes showed an unclosed macular hole at the 2-week postoperative and 52 eyes showed a closed hole. Preoperatively, MLD (P < 0.001), BD (P = 0.009) and diameter of EZ/ELM disruption (P = 0.002 and 0.025) in patients failed to close the hole after primary surgery were significantly larger than those succeeded. EZ-MH (P = 0.018), EZ-NFL (P = 0.006), EZ-GCL (P = 0.004), EZ-INL (P = 0.002), EZ-OPL (P = 0.009) and EZ-ONL (P = 0.011) angles were smaller in patients with unclosed hole. AR of the EZ-NFL (P = 0.009), EZ-GCL (P = 0.009), EZ-OPL (P = 0.023), EZ-ONL (P = 0.048) and Basal-NFL (P = 0.030) angles among the unclosed patients were significantly larger than those of the closed group. EZ-NFL (P = 0.015), EZ-GCL (P = 0.004), EZ-INL (P < 0.001), EZ-OPL (P < 0.001), EZ-ONL (P < 0.001), Basal (P = 0.023) and Basal-NFL (P < 0.001) angles of hole-unclosed patients enlarged significantly after the surgery.

Conclusions
Patients with large macular holes and an increased EZ-related angle and angle AR are more likely to experience unsuccessful outcomes following primary MH surgery. Therefore, EZ-related angles hold potential as valuable parameters for predicting the surgical outcome.

Published: November 2023

Abstract
Background
Effective interventions are needed to address suicide risk following discharge from the hospital emergency department or inpatient setting. Studies that examine follow-up contact methods show promise, but little is known about how follow-up programs are implemented in the real world and who is benefitting. The purpose of this formative evaluation and analysis was to gain insight about the usefulness and value of a partnered suicide prevention follow-up program (academic medical center emergency department partnered with a regional suicide prevention center) from the standpoint of psychiatry resident physicians providing direct care and suicide prevention center crisis counselors making follow-up outreach telephone calls to patients.

Methods
A qualitative thematic analysis was conducted with focus group data from a convenience sample of psychiatry residents who performed consultations in the emergency department setting and counselors at the suicide prevention center crisis follow-up program. Focus group sessions, using semi-structured question guides, were completed at each participant group’s workplace. Grounded theory techniques were used to guide coding and analytic theme development.

Results
Analyses resulted in four overarching themes: valuing the program’s utility and benefit to patients, desiring to understand what happens from emergency department discharge to program follow-up, having uncertainty about which patients would benefit from the program, and brainstorming to improve the referral process. Psychiatry residents appreciated the option of an “active” referral service (one that attempts to actively engage a patient after discharge through outreach), while suicide prevention crisis counselors valued their ability to offer a free and immediate service that had potential for fostering meaningful relationships. Both participant groups desired a better understanding of their partner’s program operations, a uniform and smooth referral process, and awareness of who may or may not benefit from program services.

Conclusion
Results revealed the need for improved communication and implementation, such as expanded inter-agency contacts, consistent provider training, more documentation of the requirements and rules, a consistent message about program logistics for patients, and coordination between the program elements.

AbstractRecovery housing is an important resource for those in recovery from substance use disorders. Unfortunately, we know little about its relationship to key community health risk and protective factors, potentially limiting the role it could play as a broader health resource. Leveraging county-level data on recovery residences from the National Study of Treatment and Addiction Recovery Residences (NSTARR), this study used multilevel modeling to examine Community COVID Vulnerability Index (CCVI) scores as well as availability of COVID testing and vaccination sites in relation to recovery housing. CCVI composite scores were positively associated with recovery housing availability. Analyses using CCVI thematic sub-scores found that population density and number of churches were positively associated with recovery housing availability, while epidemiological factors and healthcare system factors were negatively associated with recovery housing availability. In counties with recovery housing, there also was a positive association between CCVI and both COVID testing and vaccination availability. Recovery residences tend to be located in areas of high COVID vulnerability, reflecting effective targeting in areas with higher population density, more housing risk factors, and other high-risk environments and signaling a key point of contact to address broader health issues among those in recovery from substance use disorders.

Abstract
Background
The risk factors for mucus plug in children with adenovirus (ADV) pneumonia.

Methods and materials
A retrospective analysis was conducted of children diagnosed ADV pneumonia and underwent fiberoptic bronchoscopy admitted to the Xiamen Children's Hospital from September 2018 to September 2021.The patients were divided into a mucus plug group (39 cases) and a non-mucus plug group (53 cases). The children's data including sex, age, clinical presentation, laboratory test parameters, imaging and bronchoscopic data were collected. The risk factors for the development of airway mucus plug were analysed by multifactorial logistic regression.

Results
There were no statistically significant differences in sex, age, fever, hospitalization days, mixed infection, white blood cells (WBC) count, percentage of neutrophils (NE%), C-reactive protein(CRP), and D-dimer (all P > 0.05); Thermal range, procalcitonin (PCT), lactate dehydrogenase (LDH), Pleural effusion and associated decreased breath sounds was significantly higher in mucus plug group than in non-mucus plug group, and the differences were statistically significant (all P < 0.05); multifactorial logistic regression analysis showed that the duration of fever, PCT, and LDH were independent risk factors for the formation of mucus plugs. The critical values of ROC curves were pyroprocedure ≥ 6.5 d, PCT ≥ 0.705 ng/ml and LDH ≥ 478.5 U/L.

Conclusion
Duration of fever, PCT and LDH levels were the independent risk factors for the formation of an airway mucus plug in children with ADV pneumonia.

Published: November 2023

Abstract
Background
N6-methyladenosine (m6A) RNA modification regulators play an important role in many human diseases, and its abnormal expression can lead to the occurrence and development of diseases. However, their significance in pulpitis remains largely unknown. Here, we sought to identify and validate the m6A RNA regulatory network in pulpitis.

Methods
Gene expression data for m6A regulators in human pulpitis and normal pulp tissues from public GEO databases were analyzed. Bioinformatics analysis including Gene ontology (GO) functional, and Kyoto encyclopedia of genes and genomes (KEGG) pathway analyses were performed by R package, and Cytoscape software was used to study the role of m6A miRNA-mRNA regulatory network in pulpitis. Quantitative real-time PCR (qRT-PCR) was performed to validate the expression of key m6A regulators in collected human pulpitis specimens.

Results
Differential genes between pulpitis and normal groups were found from the GEO database, and further analysis found that there were significant differences in the m6A modification-related genes ALKBH5, METTL14, METTL3, METTL16, RBM15B and YTHDF1. And their interaction relationships and hub genes were determined. The hub m6A regulator targets were enriched in immune cells differentiation, glutamatergic synapse, ephrin receptor binding and osteoclast differentiation in pulpitis. Validation by qRT-PCR showed that the expression of methylases METTL14 and METTL3 was decreased, thus these two genes may play a key role in pulpitis.

Conclusion
Our study identified and validated the m6A RNA regulatory network in pulpitis. These findings will provide valuable resource to guide the mechanistic and therapeutic analysis of the role of key m6A modulators in pulpitis.

Published: November 2023

Abstract
Introduction
Chronic kidney disease could have a profound effect on the life of patients and family caregivers. The caregivers’ care burden increases as the disease progresses. Interventions reducing care burden should be investigated. Educational interventions could affect family caregivers’ care burden among hemodialysis patients. However, most studies and interventions have focused on caregivers. Therefore, this study aims to compare the effect of teaching Health-promoting behaviors on the care burden of family caregivers of hemodialysis patients.

Materials and methods
This trial was conducted using a pretest-posttest design and follow-up after one month. Hemodialysis patients and their family caregivers were selected using convenience sampling method. In total, 124 patient-caregiver pairs were divided into four groups of patient-centered education, caregiver-centered education, Patient and caregiver education and control by block randomization (15 blocks of 8 members and 1 block of 4 members) (n = 31 pairs per group). The intervention (teaching health-promoting behaviors) was performed in 8 sessions using the teach-back method, except for the control. The data were collected by patient and caregiver demographic forms and Novak and Guest care burden inventory as well as following the treatment regimen in three stages (before, immediately after and one month after the intervention). Demographic variables were compared among the four groups using ANOVA, Kruskal-Wallis and Chi-square test. The intragroup comparison of the main variables was made using the repeated measures ANOVA with modified LSD post hoc test. The intergroup comparison was made by one-way ANOVA with LSD post hoc test.

Results
Out of 124 caregivers participating in the study, 68 (54.8%) were female. Also, out of 124 patients participating in the study, 86 (69.4%) were male. The mean age of the caregivers and patients was 39.2 ± 11.31 and 54.23 ± 14.20 years old, respectively. There was a statistically significant difference in the mean total care burden scores of the pre-test and post-test between the four groups (p < 0.001). The total care burden decreased in patient-centered, caregiver-centered and Patient and caregiver education groups. However, this reduction in the caregiver-centered and Patient and caregiver education groups was significantly higher than the patient-centered education group (p < 0.001).

Conclusion
The results revealed teaching health-promoting behaviors reduced care burden. Moreover, caregiver-centered approach could reduce care burden more than patient-centered approach. Therefore, this could be used as a supportive method to improve the health of patients and caregivers.

Abstract
Background
Low-pass genome sequencing (LP GS) has shown distinct advantages over traditional methods for the detection of mosaicism. However, no study has systematically evaluated the accuracy of LP GS in the detection of mosaic aneuploidies and copy number variants (CNVs) in prenatal diagnosis. Moreover, the influence of sequencing depth on mosaicism detection of LP GS has not been fully evaluated.

Methods
To evaluate the accuracy of LP GS in the detection of mosaic aneuploidies and mosaic CNVs, 27 samples with known aneuploidies and CNVs and 1 negative female sample were used to generate 6 simulated samples and 21 virtual samples, each sample contained 9 different mosaic levels. Mosaic levels were simulated by pooling reads or DNA from each positive sample and the negative sample according to a series of percentages (ranging from 3 to 40%). Then, the influence of sequencing depth on LP GS in the detection of mosaic aneuploidies and CNVs was evaluated by downsampling.

Results
To evaluate the accuracy of LP GS in the detection of mosaic aneuploidies and CNVs, a comparative analysis of mosaic levels was performed using 6 simulated samples and 21 virtual samples with 35 M million (M) uniquely aligned high-quality reads (UAHRs). For mosaic levels > 30%, the average difference (detected mosaic levels vs. theoretical mosaic levels) of 6 mosaic CNVs in simulated samples was 4.0%, and the average difference (detected mosaic levels vs. mosaic levels of Y chromosome) of 6 mosaic aneuploidies and 15 mosaic CNVs in virtual samples was 2.7%. Furthermore, LP GS had a higher detection rate and accuracy for the detection of mosaic aneuploidies and CNVs of larger sizes, especially mosaic aneuploidies. For depth evaluation, the results of LP GS in downsampling samples were compared with those of LP GS using 35 M UAHRs. The detection sensitivity of LP GS for 6 mosaic aneuploidies and 15 mosaic CNVs in virtual samples increased with UAHR. For mosaic levels > 30%, the total detection sensitivity reached a plateau at 30 M UAHRs. With 30 M UAHRs, the total detection sensitivity was 99.2% for virtual samples.

Conclusions
We demonstrated the accuracy of LP GS in mosaicism detection using simulated data and virtual samples, respectively. Thirty M UAHRs (single-end 35 bp) were optimal for LP GS in the detection of mosaic aneuploidies and most mosaic CNVs larger than 1.48 Mb (Megabases) with mosaic levels > 30%. These results could provide a reference for laboratories that perform clinical LP GS in the detection of mosaic aneuploidies and CNVs.
