Imipenem-resistant multi-drug resistant (IR-MDR) Acinetobacter baumannii has been emerged as a morbidity successful nosocomial pathogen throughout the world. To address imipenem being yet the most effective antimicrobial agent against A. baumannii to control outbreaks and treat patients, a systematic review and meta-analysis was performed to evaluate the prevalence of IR-MDR A. baumannii. We systematically searched Web of Science, PubMed, MEDLINE, Science Direct, EMBASE, Scopus, Cochrane Library, Google Scholar, and Iranian databases to identify studies addressing the antibiotic resistance of A. baumannii to imipenem and the frequency of MDR strains in Iran. Out of 58 articles and after a secondary screening using inclusion and exclusion criteria and on the basis of title and abstract evaluation, 51 studies were selected for analysis. The meta-analysis revealed that 55% [95% confidence interval (CI), 53.0–56.5] of A. baumannii were resistant to imipenem and 74% (95% CI, 61.3–83.9) were MDR. The MDR A. baumannii population in Iran is rapidly changing toward a growing resistance to imipenem. Our findings highlight the critical need for a comprehensive monitoring and infection control policy as well as a national susceptibility review program that evaluates IR-MDR A. baumannii isolates from various parts of Iran.

Introduction: The prevalence of carbapenem resistance in Acinetobacter baumannii has been increasing worldwide, and therapeutic options are extremely limited. We performed a systematic review to evaluate the phenotypic and genotypic carbapenem resistance in A.baumannii reported in Iran. Methods: We systematically searched Pub Med, Web of Science Direct, and Google scholar databases to identify studies addressing the carbapenem resistance of A. baumannii. The selected papers were published between 2005 and 2016, but the sample collection period was between 2002 and 2016. To estimate the prevalence, the Der Simonian and Laird randomized models, a 95% confidence interval, was used. For the heterogeneity check, I2 test was used. The Egger test was used to check the propagation bias. Results: Analysis of data indicates that there was an increase in resistance to carbapenems from 4.5% in 2005 to a 100% prevalence rate in 2016 (65.4 (95% CI: 58.8 – 71.6). Conclusion: According to the results of this study, the rate of resistance to carbapenem in A.baumannii has been increasing in Iran. The presence of carbapenem-resistant isolates is a major concern, because carbapenem is the main drug used against Multi Drug Resistant (MDR) isolates.

Objective:To perform a systematic review and meta-analysis to determine whether fluid and imaging astrocyte biomarkers are altered in Alzheimer's disease (AD).Methods:PubMed and Web of Science databases were searched for articles reporting fluid or imaging astrocyte biomarkers in AD. Pooled effect sizes were determined with mean differences (SMD) using the Hedge’s G method with random-effects to determine biomarker performance. Adapted questions from QUADAS-2 were applied for quality assessment. A protocol for this study has been previously registered in PROSPERO (registration number: CRD42020192304).Results:The initial search identified 1,425 articles. After exclusion criteria were applied, 33 articles (a total of 3,204 individuals) measuring levels of GFAP, S100B, YKL-40 and AQP4 in the blood and cerebrospinal fluid (CSF), as well as MAO-B, indexed by positron emission tomography 11C-deuterium-L-deprenyl ([11C]-DED), were included. GFAP (SMD = 0.94; 95% CI = 0.71-1.18) and YKL-40 (SMD = 0.76; CI 95% = 0.63-0.89) levels in the CSF, S100B levels in the blood (SMD = 2.91; CI 95% = 1.01-4.8) were found significantly increased in AD patients.Conclusions:Despite significant progress, applications of astrocyte biomarkers in AD remain in their early days. The meta-analysis demonstrated that astrocyte biomarkers are consistently altered in AD and supports further investigation for their inclusion in the AD clinical research framework for observational and interventional studies.

Background Screening for cytomegalovirus (CMV)-specific antibodies is not routine in some settings. Thus, transfusion of blood products poses risks for susceptible individuals. Objectives To investigate the global pooled CMV seroprevalence among volunteer blood donors. Methods This systematic review and meta-analysis was performed according to PRISMA guidelines. The databases searched included Embase, Google Scholar, Medline, PubMed, Web of Science, and Cochrane Library. Data were extracted independently and analyzed using STATA version 11. Results The global seroprevalence of CMV IgG, CMV IgM, and both CMV IgM and IgG was 83.16% (95% confidence interval [CI]: 78.55–87.77%, I2 = 99.5%), 13.77% (95% CI: 11.59–15.95%, I2 = 98.8%), and 23.78% (95% CI: 10.50–37.06%, I2 = 98.7), respectively. Conclusion The global seroprevalence of CMV was high among blood donors. Therefore, regular CMV screening should be conducted to identify CMV-seronegative blood donors.

Background Tuberculosis (TB) preventive therapy (TPT) is an essential component of care for people living with HIV (PLHIV). We compared efficacy, safety, completion, and drug-resistant TB risk for currently recommended TPT regimens through a systematic review and network meta-analysis (NMA) of randomized trials. Methods and findings We searched MEDLINE, Embase, and the Cochrane Library from inception through June 9, 2020 for randomized controlled trials (RCTs) comparing 2 or more TPT regimens (or placebo/no treatment) in PLHIV. Two independent reviewers evaluated eligibility, extracted data, and assessed the risk of bias. We grouped TPT strategies as follows: placebo/no treatment, 6 to 12 months of isoniazid, 24 to 72 months of isoniazid, and rifamycin-containing regimens. A frequentist NMA (using graph theory) was carried out for the outcomes of development of TB disease, all-cause mortality, and grade 3 or worse hepatotoxicity. For other outcomes, graphical descriptions or traditional pairwise meta-analyses were carried out as appropriate. The potential role of confounding variables for TB disease and all-cause mortality was assessed through stratified analyses. A total of 6,466 unique studies were screened, and 157 full texts were assessed for eligibility. Of these, 20 studies (reporting 16 randomized trials) were included. The median sample size was 616 (interquartile range [IQR], 317 to 1,892). Eight were conducted in Africa, 3 in Europe, 3 in the Americas, and 2 included sites in multiple continents. According to the NMA, 6 to 12 months of isoniazid were no more efficacious in preventing microbiologically confirmed TB than rifamycin-containing regimens (incidence rate ratio [IRR] 1.0, 95% CI 0.8 to 1.4, p = 0.8); however, 6 to 12 months of isoniazid were associated with a higher incidence of all-cause mortality (IRR 1.6, 95% CI 1.2 to 2.0, p = 0.02) and a higher risk of grade 3 or higher hepatotoxicity (risk difference [RD] 8.9, 95% CI 2.8 to 14.9, p = 0.004). Finally, shorter regimens were associated with higher completion rates relative to longer regimens, and we did not find statistically significant differences in the risk of drug-resistant TB between regimens. Study limitations include potential confounding due to differences in posttreatment follow-up time and TB incidence in the study setting on the estimates of incidence of TB or all-cause mortality, as well as an underrepresentation of pregnant women and children. Conclusions Rifamycin-containing regimens appear safer and at least as effective as isoniazid regimens in preventing TB and death and should be considered part of routine care in PLHIV. Knowledge gaps remain as to which specific rifamycin-containing regimen provides the optimal balance of efficacy, completion, and safety.

Abstract BackgroundIncome level is an important factor that influences the occurrence of gestational diabetes. Thus, this systematic review and network meta-analysis aimed at evaluating the correlation between income levels and the prevalence of gestational diabetes. MethodsRelevant published studies were searched in Pubmed, Web of Science, Cochrane library, and Ovid from the establishment time of database to January 3, 2020. Finally, 13 eligible clinical studies involving 1,817,801 women were selected from a total of 3776 studies and included in this study. The statistical softwares Revman5.3 and Stata14.0 were used to compare the prevalence of gestational diabetes in five different income levels; low, lower middle, medium, upper middle, and high. ResultsThe incidences of gestational diabetes in people with different economic income levels were: high income <middle income <upper middle income <lower middle income <low income. ConclusionThere is no linear correlation between income levels and incidences of gestational diabetes. However, the overall prevalence of gestational diabetes is inversely proportional to income level, that is, the higher the income level, the lower the prevalence of gestational diabetes.

Aim: To assess if milled cobalt chromium (Co-Cr) alloy offers significantly better marginal accuracy than cast Co-Cr alloy for screw-retained long-span dental implant framework. Materials and Methods: A search PICO was formulated using suitable keywords and an electronic search was initiated. The databases of PubMed, Cochrane Library, Google Scholar and Embase were searched for related articles. Bibliographies of randomised control trials and reviews, identified in the electronic search, were analysed for studies published outside the electronically searched journals. Electronic search identified 26 studies. A total of 16 studies were eliminated after reading the abstracts. Out of the remaining 10 studies, 3 were eliminated based on the inclusion and exclusion criteria, and finally 7 studies were finalised for systematic review. Results Data were extracted from the included studies and analysed. The obtained data were suitable for meta-analysis, which showed an overall effect size z = 4.97 ( P < .001) at 95% CI showing a significant statistical difference between milled and cast Co-Cr frameworks. Conclusion: Milled cobalt chromium frameworks are significantly more accurate than cast frameworks for long-span implant-supported frameworks used in dental prosthetic rehabilitation. More randomized controlled trials need to be conducted with a larger sample size to get a more authentic conclusion in a clinical scenario.

AbstractIn order to restore fertility by vasectomy reversal, vasovasostomy (VV) is one of the most chosen options. During this procedure, the vas deferens is anastomosed either by a macro- or microscopical technique. Up to date, it is unknown which of these techniques shows best overall post-procedure patency and pregnancy rates. The purpose of this systematic review and meta-analysis is to reach a consensus on which technique is best for vasovasostomy and thereby better counsel patients and practitioners. A systematic review and meta-analysis on macroscopic and microscopic VV for vasectomy reversal was performed. PubMed, The Cochrane Library, Embase, and Web of Science were systematically searched from inception until 2019. Studies and associated data were evaluated by two reviewers. Primary, data on post-operative patency and pregnancy rates, interval to reversal, and post-operative complications were extracted. Proportions (95% CI) and heterogeneity scores (I2) were calculated, using a random effects model. A total of 8305 patients were included by 25 studies. Descriptive analysis showed higher post-operative patency (80.5% vs 91.4%) and pregnancy rates (47.7% vs 73.3%) after microscopic vasovasostomy. Meta-analysis produced post-operative patency proportions of 0.80 (95% CI, 0.76–0.84) and 0.88 (95% CI, 0.83–0.92) after macro- and microscopic VV respectively. Proportions of post-operative pregnancy were 0.43 (95% CI, 0.35–0.50) after macroscopic VV and 0.47 (95% CI, 0.31–0.62) after microsurgical VV. Microscopic VV is associated with higher post-operative patency and pregnancy rates compared to macroscopic vasovasostomy. However, further research is needed because of shortage in high methodological quality and variety.

Background: Cardiac arrhythmia cannot be overlooked in patients with coronavirus disease 2019 (COVID-19) as it carries a great influence on the outcomes. Hence, this study aimed to build concrete evidence regarding the incidence of cardiac arrhythmia in patients with COVID-19. Methods: We performed a systematic search for trusted databases/search engines including PubMed, Scopus, Cochrane library and web of science. After screening, the relevant data were extracted and the incidences from the different included studies were pooled for meta-analysis. Results: Nine studies were finally included in our study consisting of 1445 patients. The results of meta-analysis showed that the incidence of arrhythmia in patients with COVID-19 was 19.7% with 95% confidence interval (CI) ranging from 11.7 to 27.6%. There was also a significant heterogeneity (I2 = 94.67%). Conclusion: Cardiac arrhythmias were highly frequent in patients with COVID-19 and observed in 19.7% of them. Appropriate monitoring by electrocardiogram with accurate and early identification of arrhythmias is important for better management and outcomes.
