Introduction: Several observational studies have found parallels between COVID-19 pneumonia and organizing pneumonia (OP). This study aims to investigate the published literature of OP related to COVID-19, estimates the prevalence of OP among COVID-19 patients, and assesses the risk or COVID-19 severity associated with OP. Methodology: This was a systematic review and meta-analysis. A systematic electronic search through PubMed, Web of Science, Science Direct, EBSCO, and Google Scholar was conducted to include relevant and eligible literature. The authors used Review Manager 5.4 to perform quantitative data synthesis for the condition of interest analyses. Results: A total of 9 eligible study articles and 12 case reports were included in this study. The estimated pooled organizing pneumonia prevalence among COVID-19 patients was 45.6% [23.1%-68.2%]. The association between OP and severe COVID-19 infection revealed a pooled OR [95% CI] of 5.22 [-0.96-11.41]. Conclusion: COVID-19 patients had a rather high OP prevalence (43%). Surprisingly, cancer patients with COVID-19 infection had the lowest OP prevalence. OP was identified as a possible risk factor for the severity of COVID-19 infection.

Abstract Introduction Mitomycin C is a natural antibiotic that has been used to inhibit the proliferation of fibroblasts in scar tissue. Objective To evaluate the effectiveness and safety of topical Mitomycin C as an adjuvant in the endoscopic treatment of laryngotracheal stenoses. Data synthesis A systematic review of experimental or observational studies that have evaluated the treatment of laryngotracheal stenoses with the use of topical Mitomycin C was performed. Databases researched: LILACS, PubMed, Embase, Cochrane and Web of Science. Outcomes: resolution (symptom-free time ≥ one year), number of procedures required, and complications resulting from the procedure. A total of 15 studies (involving 387 patients) were selected. Mitomycin C was administered to every patient in 11 studies, and in 4 other studies, the patients were separated into 2 groups, 1 receiving mitomycin C, and the other not. The resolution of the stenosis evaluated in 12 studies in which the patients received mitomycin C was of 69% (95% confidence interval [95%CI]: 61–76%; I2 = 17.3%). A total of 52% of the patients (95%CI: 39–64%, 11 studies; I2 = 64.7%) were submitted to a single endoscopic procedure, and 48% (95%CI: 36–61%, 11 studies; I2 = 64.7%) were submitted to more than 1 procedure. Complications (mediastinal and subcutaneous emphysema, dysphonia, laceration or vocal fold paralysis and acute light obstruction) were reported in 9% of the patients (95%CI: 3–18%, 9 studies; I2 = 79.8%). Conclusions The evidence suggests that mitomycin C is an effective and safe option in the endoscopic treatment of laryngotracheal stenosis.

IntroductionAcute diverticulitis of the sigmoid colon is increasingly treated by a non-operative approach. The need for colectomy after recovery from a flare of acute diverticulitis of the left colon, complicated diverticular abscess is still controversial. The primary aim of this study is to assess the risk of interval emergency surgery by systematic review and meta-analysis.Methods and analysisThe systematic review and meta-analysis will be conducted in accordance to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statement. PubMed/MEDLINE, Cochrane Central Register of Controlled Trials and EMBASE will be screened for the predefined searching term: (Diverticulitis OR Diverticulum) AND (Abscess OR pelvic abscess OR pericolic abscess OR intraabdominal abscess) AND (surgery OR operation OR sigmoidectomy OR drainage OR percutaneous drainage OR conservative therapy OR watchful waiting). All studies published in an English or German-speaking peer-reviewed journal will be suitable for this analysis. Case reports, case series of less than five patients, studies without follow-up information, systematic and non-systematic reviews and meta-analyses will be excluded. Primary endpoint is the rate of interval emergency surgery. Using the Review Manager Software (Review Manager/RevMan, V.5.3, Copenhagen, The Nordic Cochrane Centre, The Cochrane Collaboration, 2012) meta-analysis will be pooled using the Mantel-Haenszel method for random effects. The Risk of Bias in Non-randomized Studies of Interventions tool will be used to assess methodological quality of non-randomised studies. Risk of bias in randomised studies will be assessed using the Cochrane developed RoB 2-tool.Ethics and disseminationAs no new data are being collected, ethical approval is exempt for this study. This systematic review is to provide a new insight on the need for surgical treatment after a first attack of acute diverticulitis, complicated by intra-abdominal or pelvic abscesses. The results of this study will be presented at national and international meetings and published in a peer-reviewed journal.PROSPERO registration numberCRD42020164813.

AbstractThe aim of this systematic review was to perform qualitative and quantitative analysis on the toxic effects of chloroquine (CQ) and hydroxychloroquine (HCQ) on skeletal muscles. We designed the study according to PRISMA guidelines. Studies for qualitative and quantitative analyses were selected according to the following inclusion criteria: English language; size of sample (> 5 patients), adult (> age of 18) patients, treated with CQ/HCQ for inflammatory diseases, and presenting and not presenting with toxic effects on skeletal muscles. We collected data published from 1990 to April 2020 using PubMed, Cochrane Library, EMBASE, and SciELO. Risk of bias for observational studies was assessed regarding the ROBIN-I scale. Studies with less than five patients (case reports) were selected for an additional qualitative analysis. We used the software Comprehensive Meta-Analysis at the confidence level of 0.05. We identified 23 studies for qualitative analysis (17 case-reports), and five studies were eligible for quantitative analysis. From case reports, 21 patients presented muscle weakness and confirmatory biopsy for CQ/HCQ induced myopathy. From observational studies, 37 patients out of 1,367 patients from five studies presented muscle weakness related to the use of CQ/HCQ, and 252 patients presented elevated levels of muscle enzymes (aldolase, creatine phosphokinase, and lactate dehydrogenase). Four studies presented data on 34 patients with confirmatory biopsy for drug-induced myopathy. No study presented randomized samples. The chronic use of CQ/HCQ may be a risk for drug-induced myopathy. There is substantiated need for proper randomized trials and controlled prospective studies needed to assess the clinical and subclinical stages of CQ/HCQ -induced muscle myopathy.

Background: Cognitive impairment is one of the most common, burdensome, and costly disorders in the elderly worldwide. The magnitude of the association between anemia and overall cognitive impairment (OCI) has not been established. Objective: We aimed to update and expand previous evidence of the association between anemia and the risk of OCI. Methods: We conducted an updated systematic review and meta-analysis. We searched electronic databases, including EMBASE, PubMed, and Web of Science for published observational studies and clinical trials between 1 January 1990 and 1 June 2020. We excluded articles that were in the form of a review, letter to editors, short reports, and studies with less than 50 participants. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. We estimated summary risk ratios (RRs) with random effects. Results: A total of 20 studies, involving 6558 OCI patients were included. Anemia was significantly associated with an increased risk of OCI (adjusted RR (aRR) 1.39 (95% CI, 1.25–1.55; p < 0.001)). In subgroup analysis, anemia was also associated with an increased risk of all-cause dementia (adjusted RR (aRR), 1.39 (95% CI, 1.23–1.56; p < 0.001)), Alzheimer’s disease [aRR, 1.59 (95% CI, 1.18–2.13; p = 0.002)], and mild cognitive impairment (aRR, 1.36 (95% CI, 1.04–1.78; p = 0.02)). Conclusion: This updated meta-analysis shows that patients with anemia appear to have a nearly 1.39-fold risk of developing OCI than those without anemia. The magnitude of this risk underscores the importance of improving anemia patients’ health outcomes, particularly in elderly patients.

Abstract BackgroundThe novel coronavirus 2019 (COVID-19) outbreak has put a great burden on global health and healthcare systems. One of the vulnerable groups to COVID-19 infection and complications is the pregnant women. There is controversy regarding the possibility of vertical transmission of COVID-19 from mother to infant. The aim of this systematic review and meta-analysis was to assess the possibility of vertical transmission of COVID-19 based on currently published literature including observational studies. All published articles including case reports, case series,MethodsThis study will be conducted on all published observational studies, including cross-sectional studies, cohort, case-control, case reports, and case series, in peer reviewed journals in any language until the end of March 2020. Editorials, commentaries and letter to editors will be excluded from the review. Search will be conducted in international bibliographic databases including PubMed, Embase, and Web of Science based on preferred reporting items for systematic reviews and meta-analysis (PRISMA) checklist. Primary search will be performed in PubMed and Embase using the Coronavirus 2019 and vertical transmission keywords based on medical subject heading (MeSH) terms along with free text searching in combination with Boolean operations. The search strategy will be improved and finalized based on the results of the primary search. The World Health Organization (WHO) and google scholar websites will be searched as grey literature. Articles will be reviewed by two authors independently for the relevance of titles and abstracts. Data extraction of the included articles will be performed by two researchers using the Zotero and review manager (revMan) software. Heterogeneity of the articles will be assessed using DerSimonian & Laird Q test and I 2 statistic. The pooled estimated prevalence of vertical transmission of COVID-19 will be performed using the Metaprop command. Publication bias will be assessed using the Begg's rank correlation and the Egger weighted regression methods.DiscussionThe findings of this systematic review and meta-analysis will help practitioners and health care providers in decision making for the care and management of COVID-19 infected pregnant women.

Abstract To evaluate the efficacy of N95 respirators and medical masks for protection against respiratory infectious diseases, including COVID-19. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies evaluating the use of N95 respirators and medical masks for protection against respiratory infectious diseases. We retrieved relevant articles published from January 1994 to January 2020 by searching the PubMed, EMBASE, Cochrane CENTRAL, and Web of Science databases. The study quality was evaluated using the Cochrane Risk of Bias tool with RevMan 5.3 software. Eleven RCTs adjusted for clustering were included in the meta-analysis. Compared with the control group, N95 respirators or medical masks conferred significant protection against respiratory infectious diseases (odds ratio (OR) = 0.50; 95% CI: 0.29–0.84). Compared to medical masks, N95 respirators conferred significant protection against respiratory infectious diseases (OR = 0.75; 95% confidence interval (CI): 0.57–0.99). Meta-analysis of 10 observational studies adjusting for clustering also suggested that N95 respirators and medical masks are effective for protection against respiratory infectious diseases (OR = 0.59; 95% CI: 0.42–0.82). However, only one case report showed the effectiveness of medical masks for preventing COVID-19. Although medical masks and N95 respirators may confer significant protection against respiratory infectious diseases, there is insufficient evidence to conclude that these types of personal protective equipment offer similar protection against COVID-19. Therefore, in the absence of sufficient resources during an epidemic, medical masks and N95 respirators should be reserved for high-risk, aerosol-generating producing procedures.

Introduction: The prevalence of venous (VTE) and arterial (ATE) thromboembolic events in patients with COVID-19 remains largely unknown. Methods: In this systematic review and meta-analysis, we systematically searched Pubmed MEDLINE, Google Scholar, and Web of Science for observational studies describing the prevalence of VTE and ATE amongst patients with COVID-19 published between Jan 1, 2020 and May 20, 2020. The websites of major journals were also searched. Results: We analysed findings from 15 studies totalizing 1,755 patients, mainly in intensive care units (ICU). The weighted frequency of COVID-19-related VTE was 16.6% (95%CI 9.5-25.1%, I 2 =94%, 13 studies: 1,546 patients). The overall prevalence of PE and deep vein thrombosis (DVT) were 9.1% (95%CI 3.7-16.6%, I 2 =95%; 15 studies; 1,755 patients) and, 7.8% (95%CI 3.4-13.8%; I 2 =92%; 13 studies; 1,445 patients), respectively. Few were isolated subsegmental PE or distal DVT. The VTE prevalence was significantly higher in ICU (21.6%; 95%CI 12.6-32.2%; I2=91% versus 4.6%; 95%CI 1.0-10.7%, I 2 =87%, p interaction =0.002 in subgroup analysis). The weighted frequency of myocardial infarction/acute coronary syndrome, stroke, and other ATE (6 studies, 812 patients) was 3.2% (95%CI 2.1-4.5%, I 2 =0%), 0.7% (95%CI 0.0-2.2%, I 2 =64%), 2.0% (95%CI 1.2-3.0%, I 2 =40%), and 0.5% (95%CI 0.0-1.6%, I 2 =60%), respectively. Conclusions: Patients admitted in the ICU for severe COVID-19 had a high risk of VTE. Conversely, further studies are needed to determine the specific effects of COVID-19 on the risk of ATE or VTE in less severe forms of the disease.

Background and Purpose Post-stroke fatigue is a debilitating and long-lasting condition. However, there are uncertainties regarding its prevalence and variability between studies. This review aims to estimate the prevalence of fatigue and determine the factors responsible for its variation in the literature. Methods A systematic review was conducted for all published studies (search to November 2020) using AMED, CINAHL, EMBASE, MEDLINE, PsycINFO, SCOPUS and Web of Science. Papers were included if they recruited participants with stroke, used a validated scale to measure fatigue and were in English. Two reviewers screened and assessed the relevant studies for eligibility ( n = 96). The included papers were appraised using the Joanna Briggs Institute (JBI) tool for prevalence studies, and data were extracted by one reviewer. To understand the variation in PSF prevalence between papers, data were pooled and analysed based on relevant methodological (e.g. time of assessment) or clinical factors (e.g. depression) using Review Manager 5.4 software. Results While 48 studies were included and summarised ( N = 9004), only 35 were appropriate for the meta-analysis ( N = 6851). The most frequently used tool to measure fatigue was the Fatigue Severity Scale (FSS) ( n = 31). The prevalence was calculated with a cut-off point of four or more using FSS and resulted in an estimate of 48% (95% CI 42–53%). Time of assessment (<6 vs ≥6 months), stroke type (ischaemic vs haemorrhagic/subarachnoid haemorrhage) and geographical location (East Asia vs Europe) could explain the prevalence variation between studies. Conclusions Fatigue is prevalent among stroke survivors. This condition varies in terms of occurrence between studies; however, time of assessment, stroke type and geographical location might explain this variation. As this review estimates the overall burden of fatigue after stroke, it provides a useful indicator to inform policy, planning and healthcare professionals. Further efforts are required to investigate the mechanisms that lead to PSF, particularly in the groups that show high prevalence, in order to prevent or alleviate it.

ABSTRACT The accelerated modernization process has entailed changes in the lifestyle of people, such as exposure to sedentary behavior, and this in turn may affect the nutritional status. The aim of this systematic review with meta-analysis was to analyze observational studies that assessed the association between exposure time to sedentary behavior and nutritional status (overweight/malnutrition) in individuals aged ≥60 years. BVS, PubMed and Web of Science were the databases used in the search for observational studies, published until November 28, 2017, which have examined the association between exposure time to sedentary behavior and nutritional status. Two authors undertook the reading of titles and abstracts and applied the STROBE checklist independently. The Odds Ratio was calculated using the random effects model. Eight studies were included in this meta-analysis and involved 21415 individuals. All the studies covered most of the items suggested by the STROBE checklist. Of the total, four studies showed association between sedentary behavior and nutritional status. Longer exposure to sedentary behavior did not increase the odds of overweight and/or obesity (OR 1.32; 95%; CI 0.95-1.84). It is suggested that further studies with standardized criteria for measuring sedentary behavior and nutritional status are undertaken. Level of Evidence II; Systematic review of level II studies.

Abstract Cytochrome P450 (CYP) is involved in the metabolism of nevirapine (NVP); especially, CYP2B6 has been known to be one of the main enzymes involved in NVP metabolism. The objective of this study was to investigate the effects of CYP2B6 variants on plasma concentrations of NVP by a systematic review and meta-analysis. A search for qualifying studies published until April 2020 was conducted using the EMBASE, PubMed, and Web of Science databases. The mean difference (MD) and 95% confidence intervals (CIs) were calculated. Data analysis was performed using R Studio (version 3.6) and Review Manager (version 5.3). In total, data from six studies involving 634 patients were analyzed in the systematic review and five studies in the meta-analysis. We found that carriers of the CYP2B6 516TT genotype had a 2.18 µg/mL higher NVP concentration than did the GG or GT (95% CI 1.28–3.08). In the respective comparisons of the three genotypes, it was found that the MD was 1.87 µg/mL between the TT and GT groups, 2.53 µg/mL between TT and GG, and 0.60 µg/mL between GT and GG. This meta-analysis confirmed that CYP2B6 polymorphisms was associated with plasma NVP concentrations. Therefore, CYP2B6 genotyping may be useful to predict the responses to NVP.
