Mitomycin C in the Endoscopic Treatment of Laryngotracheal Stenosis: Systematic Review and Proportional Meta-Analysis

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.

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.

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 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.

Modernization Process

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.

Background: This systematic review and meta-analysis of the observational studies aimed at evaluating the infertile women’s attitude toward gestational surrogacy. Methods: Published studies until Jan 2019 were searched using PubMed/MEDLINE, Scopus, EMBASE, Cochrane Library, ISI Web of Science, Proquest and Google scholar, MagIran, SID and IranMedex. Studies in English or Persian language surveyed attitudes toward surrogacy for infertile women published until Jan 2019. Animal studies and studies with poor methodological quality were excluded from the review. Results: Six eligible studies including 1359 infertile women were identified. Of these, 559 and 742 women agreed and disagreed with surrogacy respectively. The overall event rate of positive attitude for surrogacy in infertile women was %39.7 (%95 CI=24.5 to 57.1, P=0.245). Conclusion: The infertile women’s attitude toward surrogacy is not strongly positive. We believe, more studies should be conducted among different socioeconomic, religious and cultural groups.

There is increasing evidence for oral lesions and manifestations of COVID-19. The aim of this meta-analysis was to investigate the types of oral manifestations of COVID-19 and their prevalence. PubMed/Medline, Scopus, Web of Science, and Google Scholar databases were used to search for publications on oral manifestations in patients with PCR-confirmed COVID-19. A total of 310 records were selected, and 74 were included. Oral lesions in COVID-19 were classified according to their etiologies, including iatrogenic lesions caused by intubation and opportunistic infections. Of the included studies, 35 reported oral lesions probably caused by severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) infection. Meta-analysis of prevalence data on oral manifestations and aphthous lesions indicated high heterogeneity, while meta-analysis of xerostomia prevalence data revealed a pooled prevalence, with considerable heterogeneity. In conclusion, the meta-analysis yielded high heterogeneity between studies: oral lesions yielded a prevalence of 0.33 (95% CI 0.11–0.60), xerostomia lesions a prevalence of 0.44 (95% CI 0.36–0.52) and aphthous lesions 0.10 (95% CI 0.01–0.24). In addition, a gap in the evidence regarding the prevalence of oral lesions in COVID-19 was identified and the need for further observational studies focusing on this issue and on the causal relationships between oral lesions and COVID-19 was highlighted.

Abstract Objectives To investigate whether a possible association of mobile phone use with hearing impairment was conducted a systematic review and meta-analysis. Content This is a systematic review and meta-analysis. A comprehensive literature search was carried out based on the Meta-analysis of Observational Studies in Epidemiology (MOOSE) methodology using PubMed, Scopus, Web of Science, OVID, and Cochrane. The Robins-I tool was used for quality assessment and risk of bias. Two investigators independently reviewed all articles. Pooled effect size was calculated and meta-analysis was performed to compute an overall effect size. Summary Overall, five relevant studies (two cross-sectional and three cohort studies) with 92,978 participants were included in the analysis. The studies were stratified by design, there was no significant association between mobile phone use and hearing impairment in cross-sectional studies (OR=0.94, 95% CI=0.57–1.31) and cohort studies (OR=1.09, 95% CI=0.93–1.25). In addition, the effect estimates did not differ significantly between cross-sectional and cohort studies (Q=0.50, p=0.48). Overall, the pooled odds ratio (OR) of hearing impairment was 1.07 (95% CI: 0.94–1.20), which indicates no significant association between mobile phone use and hearing impairment. Outlook Our findings indicate no association between mobile phone use and hearing impairment. However, these findings must be interpreted with caution.

Abstract Background ERAS programs are not only used in abdominal surgeries, they are also used in cardiothoracic, gynecology, urology, orthopedic, and neurosurgery. Many authors and surgeons worldwide have been adapting this program, also trying to modify it due to its promising outcomes and it’s low damage toit’s continence. Objective To present an updated assessment of perioperative care in colorectal surgery from the available evidence and Enhanced Recovery After Surgery (ERAS) group recommendations. Patients and Methods We performed this systematic review and meta-analysis in accordance to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) statement. PRISMA and MOOSE are reporting checklists for Authors, Editors, and Reviewers of Meta-analyses of interventional and observational studies. According to International committee of medical journal association (ICJME), reviewers must report their findings according to each of the items listed in those checklists. An electronic search was conducted from the inception till March 2019 in the following bibliographic databases: Medline via PubMed, SCOPUS, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and Google Scholar to identify relevant articles. We used different combinations of the following queries: ("Colorectal Surgery"[Mesh]) AND ("Enhanced recovery" OR "conventional care"). The search have been done with no limit regarding the year publication or language. Results In the present study, we searched Medline via PubMed, SCOPUS, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar from their inception till March 2019. The search retrieved 2861 unique records. We then retained 41 potentially eligible records for full-texts screening. Finally, 28 reports of 25 RCTs were included in the present systematic review and meta-analysis Conclusion ERAS was proven to be feasible, minimally invasive, cheap, relatively easy, which is safe and effective at the same time. This program can be ideal for patients undergoing elective colo-rectal surgery, yet more studies should be conducted in Egypt to compare results regarding different approaches of this program with longer follow up and randomization of patients.

Abstract. Backgrounds: Central obesity, as a pivotal component of metabolic syndrome is associated with numerous co-morbidities. Dietary factors influence central obesity by increased inflammatory status. However, recent studies didn’t evaluate the association between central obesity and dietary inflammation index (DII®) that give score to dietary factors according to their inflammatory potential. In the current systematic review and meta-analysis, we summarized the studies that investigated the association between DII® with central obesity indices in the general populations. Methods: In a systematic search from PubMed, SCOPUS, Web of Sciences and Cochrane electronic databases, we collected relevant studies written in English and published until 30 October 2019. The population of included studies were apparently healthy subjects or individuals with obesity or obesity-related diseases. Observational studies that evaluated the association between DII® and indices of central obesity including WC or WHR were included. Results: Totally thirty-two studies were included; thirty studies were cross-sectional and two were cohort studies with 103071 participants. Meta-analysis of observational studies showed that higher DII® scores were associated with 1.81 cm increase in WC (Pooled weighted mean difference (WMD) = 1.813; CI: 0.785–2.841; p = 0.001). Also, a non-significant increase in the odds of having higher WC (OR = 1.162; CI: 0.95–1.43; p = 0.154) in the highest DII category was also observed. In subgroup analysis, the continent, dietary assessment tool and gender were the heterogeneity sources. Conclusion: The findings proposed that adherence to diets with high DII® scores was associated with increased WC. Further studies with interventional designs are necessary to elucidate the causality inference between DII® and central obesity indices.
