Background: Maternal COVID-19 infection has been reported to be associated with an increase in the rates of C-sections. However, studies have not reported this association consistently. Therefore, this systematic review and meta-analysis were conducted regarding this issue. Methods: We identified all publications up to January 2021 in databases of PubMed, Scopus, and Web of Science. In addition, we reviewed gray literature and conference proceedings. The pooled odds ratios (OR) and 95% confidence intervals (CI (measured from eligible studies were used as random effect estimates of association among studies. Heterogeneity testing using I2 statistics was performed to assess variance between the studies. Results: The pooled estimates of OR did not report a significant association between COVID-19 and the risk of cesarean section, respectively (OR = 2.02, 95% CI = 0. 4 to 3.64). There was low heterogeneity among the studies reporting the risk of diseases associated with cesarean section among children based on OR (I2=12.7%, P=0.333). The P values for Begg’s and Eggerʼs regression were 0.573 and 0.555, respectively. Conclusion: While we did not find an association between COVID-19 and increased rates of cesarean sections, we cannot exclude a type II error; therefore, additional studies, including large cohort studies by controlling confounding variables, should be performed in the future.

Background The antihelminthic drug praziquantel has been used as the drug of choice for treating schistosome infection for more than 40 years. Although some epidemiological studies have reported low praziquantel efficacy in cure rate (CR) and/or egg reduction rate (ERR), there is no consistent robust evidence of the development of schistosome resistance to praziquantel (PZQ). There is need to determine factors that lead to variable treatment CR and/or ERR. Therefore, we conducted a systematic review and meta-analysis to review CR and ERR as well as identify their predictors. Methodology/Principal findings In this systematic review and meta-analysis, a literature review was conducted using Biosis Citation Index, Data Citation Index, MEDLINE, and Web of Science Core Collection all of which were provided through Web of Science. Alongside these, EMBASE, and CAB abstracts were searched to identify relevant articles. Random effect meta-regression models were used to identify the factors that influence CR and/or ERR by considering differences in host characteristics and drug dose. In total, 12,127 potential articles were screened and 146 eligible articles (published from 1979 to 2020) were identified and included for the meta-analysis. We found that there has been no significant reduction in CR or ERR over the study period. The results showed more variability in CR, compared with ERR which was more consistent and remained high. The results showed a positive effect of “PZQ treatment dose” with the current recommended dose of 40 mg/kg body weight achieving 57% to 88% CR depending on schistosome species, age of participants, and number of parasitological samples used for diagnosis, and ERR of 95%. Conclusions/Significance Based on a review of over 40 years of research there is no evidence to support concerns about schistosomes developing resistance to PZQ. These results indicate that PZQ remains effective in treating schistosomiasis.

Objectives: Phobia of natural childbirth is one of the most important and influencing factors leading women to request cesarean sections. The present study aimed to prepare a systematic review and meta-analysis to investigate the type of interventions related to fear of childbirth (FOC). Materials and Methods: The data collection was based on an extensive search of articles related to clinical trials (1990-2019) posted on Google Scholar, Cochran, SID, Magiran, Web of Science, Scopus, and PubMed electronic databases. In general, 109 abstracts were selected after eliminating similar publications. As a result of the qualitative evaluations of these articles, 11 studies were kept for investigation. Results: The studies were categorized into three groups including prenatal education with childbirth counseling, yoga courses, and psychoeducational-based interventions. Based on the meta-analysis, psychoeducational interventions have a significant effect on childbirth fears and anxiety in comparison with the control group (mean difference: 0.85, 95% CI: -1.20–0.45, P < 0.0001, I2 = 82%). Conclusions: Psychologically-based interventions, can creatively play an essential role in reducing the FOC during pregnancy and even childbirth. It can also create a pleasant and traumatic-free experience which is essential for encouraging women to have a natural childbirth.

The aim of this systematic review and meta-analysis was to estimate the pooled occurrence of ventilator-associated pneumonia (VAP) among patients admitted to an intensive care unit with COVID-19 and mortality of those who developed VAP. We performed a systematic search on PubMed, EMBASE and Web of Science from inception to 2nd March 2021 for nonrandomized studies specifically addressing VAP in adult patients with COVID-19 and reporting data on at least one primary outcome of interest. Random effect single-arm meta-analysis was performed for the occurrence of VAP and mortality (at the longest follow up) and ICU length of stay. Twenty studies were included in the systematic review and meta-analysis, for a total of 2611 patients with at least one episode of VAP. The pooled estimated occurrence of VAP was of 45.4% (95% C.I. 37.8–53.2%; 2611/5593 patients; I2 = 96%). The pooled estimated occurrence of mortality was 42.7% (95% C.I. 34–51.7%; 371/946 patients; I2 = 82%). The estimated summary estimated metric mean ICU LOS was 28.58 days (95% C.I. 21.4–35.8; I2 = 98%). Sensitivity analysis showed that patients with COVID-19 may have a higher risk of developing VAP than patients without COVID-19 (OR 3.24; 95% C.I. 2.2–4.7; P = 0.015; I2 = 67.7%; five studies with a comparison group).

Objective: Studies conducted on severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and COVID-19 epidemics have shown PTSD can occur during and after infectious diseases. However, more studies are needed to explore PTSD during and after COVID-19 outbreak. The objective of this study is to provide a protocol of systematic review and meta-analysis to report the global prevalence of PTSD during and after coronavirus pandemics among general population, health care workers, survivors, or patients with coronaviruses. Method: We include all studies that reported the prevalence of PTSD during and after coronavirus pandemics and search databases, including Web of Science, PubMed, Scopus, Embase, and Google Scholar from first of November 2002 to May 18, 2020. Two authors independently use relevant checklists to quality assessment of the included studies and extract data. We use the graphical methods and fixed or random effect models to aggregate prevalence estimates. Also, we will assess heterogeneity between the included studies using the I2 heterogeneity statistic and use subgroup and sensitivity analysis to assess the sources of heterogeneity. Discussion: We infer that PTSD is a common experience during and after infectious disease pandemics, especially COVID-19. The findings of this study can be used by health policymakers and other stakeholders and will provide a path to future studies.

Overweight/obesity is one of the most important health problem worldwide. Birth by cesarean section has been shown to influence long-term health outcome including obesity. The aim of this systematic review-meta-analysis is to examine whether cesarean section increases the risk of offspring&rsquo; s overweight/obesity. The study follows the PRISMA and MOOSE guidelines. A systematic literature search was con-ducted on Scopus, PubMed, and WoS until December 2020. For inclusion, studies must have re-ported either (I) both Birth by cesarean section and adult (&ge; 18 years) offspring BMI, (II) cohort or case&ndash;control study design and (III) a risk estimate. Heterogeneity testing was performed using Cochran's Q and I2 statistics. Publication bias was assessed by Egger&rsquo;s test and Begg&rsquo;s test. Me-ta-analysis was performed through a random effect model. Eleven studies with a combined population of 180.408 subjects were included in the meta-analysis. The overall analysis (n = 18) yielded a combined risk estimate for overweight/obesity of 1.19 (95% CI 1.08-1.31) and the test of heterogeneity resulted Q=53,37 (I2 = 70,37 %, P&le;0&bull;0001). The risk of offspring obesity is 1.23 (95% CI 1.09-1.39) and the test of heterogeneity resulted Q=39.50 (I2= 72,15%, P&le;0&bull;0001). Children born by cesarean section have an increased risk of developing obesity in adulthood

Background: Although, some clinical trials investigated the maternal and neonatal effect of fentanyl as a premedication before induction of general anesthesia in cesarean section, to the best of our knowledge, there is no systematic review to summarize these results. Objectives: The present systematic review and meta-analysis evaluated the maternal and neonatal effect of intravenous fentanyl as a premedication before induction of general anesthesia in cesarean section. Methods: The databases of Pubmed, Embase, Scopus and Cochrane library were searched till July 2017 to identify randomized clinical trials which evaluated the effects of intravenous fentanyl as a premedication before induction of general anesthesia compared with placebo on neonate first and fifth minute Apgar score and maternal heart rate and mean arterial pressure (MAP) in cesarean section. Standard Mean difference (SMD) was calculated and I-square statistic test was used for heterogeneity analysis. Results: The present systematic review and meta-analysis consisted of three clinical trials including 180 women in labor. Considering the results of meta-analysis, there is no significant differences between fentanyl and placebo in the case of Apgar score at 1 minute; however, the Apgar score of 5 minutes was significantly lower in fentanyl group compared with placebo (SMD -0.68, 95%CI: - 0.98, -0.38, p<0.001). In the term of maternal hemodynamics, the heart rate (SMD -0.43, 95%CI: - 0.72, -0.13, p=0.004) and MAP (SMD -0.78, 95% CI: -1.09, -0.48, p<0.001) in fentanyl group were significantly lower compared with placebo group. Conclusion: The present meta-analysis showed that using intravenous fentanyl as a premedication before induction of general anesthesia had adverse effects on neonate Apgar score. However, it had positive effects on preventing adverse consequences of intubation on maternal hemodynamics.

Background: The evidence indicates that the optimal observation period following renal biopsy ranges between 6 and 8 h. This systematic review and meta-analysis explored whether differences exist in the complication rates of renal biopsies performed in outpatient and inpatient settings. Methods: We searched the MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews from 1985 to February 2020. Two reviewers independently selected studies evaluating the bleeding risk from renal biopsies performed in outpatient and inpatient settings and reviewed their full texts. The primary and secondary outcomes were risks of bleeding and major events (including mortality) following the procedure, respectively. Subgroup analysis was conducted according to the original study design (i.e., prospective or retrospective). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random effect meta-analysis. Heterogeneity was assessed using the I2 test. Results: Data from all 10 eligible studies, which included a total of 1801 patients and 203 bleeding events, were included for analysis. Renal biopsies in outpatient settings were not associated with a higher bleeding risk than those in inpatient settings (OR = 0.81; 95% CI, 0.59–1.11; I2 = 0%). The risk of major events was also comparable across both groups (OR = 0.45; 95% CI, 0.16–1.29; I2 = 4%). Conclusions: Similar rates of bleeding and major events following renal biopsy in outpatient and inpatient settings were observed.

The Relationship

Cognitive functions are essential in any form of exercise. Recently, interest has mounted in addressing the relationship between caffeine intake and cognitive performance during sports practice. This review examines this relationship through a structured search of the databases Medline/PubMed and Web of Science for relevant articles published in English from August 1999 to March 2020. The study followed PRISMA guidelines. Inclusion criteria were defined according to the PICOS model. The identified records reported on randomized cross-over studies in which caffeine intake (as drinks, capsules, energy bars, or gum) was compared to an identical placebo situation. There were no filters on participants’ training level, gender, or age. For the systematic review, 13 studies examining the impacts of caffeine on objective measures of cognitive performance or self-reported cognitive performance were selected. Five of these studies were also subjected to meta-analysis. After pooling data in the meta-analysis, the significant impacts of caffeine only emerged on attention, accuracy, and speed. The results of the 13 studies, nevertheless, suggest that the intake of a low/moderate dose of caffeine before and/or during exercise can improve self-reported energy, mood, and cognitive functions, such as attention; it may also improve simple reaction time, choice reaction time, memory, or fatigue, however, this may depend on the research protocols.
