AbstractEmerging evidence suggest association of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with the development of many liver abnormalities. The overarching aim of this study was therefore to assess the available evidence on the clinical effects of SARS-CoV-2 on the profiles of liver chemistries and coagulation in COVID-19 diagnosed patients. We considered all study designs including epidemiological and observational that reported liver function test abnormalities in patients confirmed with SARS-CoV-2 infection. Medline, Embase databases and Google Scholar as well as relevant reviews were searched to identify appropriate studies from inception to 31st of August 2020. We calculated the pooled mean with 95% confidence intervals (95% CI) through a random-effect model meta-analysis. A total of 35 studies with 10,692 participants were considered for the review from which 23 studies with sufficient quantitative data were included in the meta-analysis. The pooled mean for liver enzymes and coagulation parameters did not significantly change in patients diagnosed with COVID-19 and remained within normal range. Notwithstanding potential bias from confounding factors in interpretation of data in this review, findings from the observational studies and case reports suggest that COVID-19 does not appear to have a significant impact on the transaminases or total bilirubin levels of patients with confirmed SARS-CoV-2 infection. Further controlled studies and larger sample size observational studies are needed with adequate reporting of other liver function parameters are warranted.

Abstract Emerging evidence suggest association of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with development of many liver abnormalities. The overarching aim of this study was therefore to assess the available evidence on the clinical effects of SARS-CoV-2 on liver function laboratory tests and coagulation profile in affected individuals. We considered all study designs including epidemiological and observational that reported liver function test abnormalities in patients diagnosed with SARS-CoV-2 infection. Medline, Embase databases and Google Scholar as well as relevant reviews were searched to identify appropriate studies from inception to April 30th, 2020. We calculated pooled mean with 95% confidence intervals (95%CI) through a random-effect model meta-analysis. A total of 29 studies with 9991 participants were considered for the review from which 20 studies with sufficient quantitative data were included for the meta-analysis. The pooled mean for liver enzymes and coagulation parameters did not significantly change in patients affected by COVID-19 and remained within normal range. Our systematic review and meta-analysis findings of the available evidence suggest that COVID-19 did not have a significant impact on the liver enzymes or coagulation profile of patients with SARS-CoV-2 infection. Future studies need to adequately report all the liver function parameters with event rates.

Abstract Background: Remdesivir, a nucleoside analogue antiviral drug developed for Ebola, is approved by the US Food and Drug Administration for the treatment of COVID-19. However, the findings of randomised controlled trials (RCTs) and observational studies vary regarding the effectiveness of remdesivir. We aimed to comprehensively review the available evidence identify the effectiveness and safety of remdesivir in patients with COVID-19.Methods: Seven databases (PubMed, Web of Science, Embase, Wanfang database, SinoMed, Chinese National Knowledge Infrastructure and Chinese Science Journal Database) were searched for literatures published until November 2020.Following the PRISMA flow diagram, we included RCTs and prospective observational studies that reported the effectiveness and safety of remdesivir in patients with COVID-19. With extracting study details, as well as patient characteristics and outcomes, data were meta-analyzed by using Review Manager software version 5.4.1. Meta-analyses were conducted with fixed-effect model or random-effect model to calculate risk ratio (RR).Results: Four studies involving 2,279 patients were included in this meta-analysis. Compared with placebo, 10-day remdesivir was associated with significant increased clinical improvement on days 14 and 28 with RR 1.19 (95%CI 1.09-1.30) and RR 1.09 (95%CI 1.03-1.16). The clinical improvement of 5-day remdesivir was better than 10-day remdesivir on days 7 with RR 1.20 (95%CI 1.02-1.41), but the efficacy advantage of 5-day remdesivir disappeared on days 14 (RR 1.08; 95%CI 0.90-1.29). Remdesivir was associated with lower serious adverse events rates and grade 3 or 4 adverse events rates as compared with placebo with RR 0.75(95%CI 0.63-0.89) and RR 0.89(95%CI 0.80-0.99). Compared with 10-day remdesivir, 5-day remdesivir for patients with COVID-19 decreased the risk of serious adverse events rates and grade 3 or 4 adverse events rates with RR 0.65(95%CI 0.47-0.88) and RR 0.74 (95%CI 0.58-0.95). Conclusions: Our meta-analysis suggested that remdesivir would increase clinical improvement conditions and decrease serious adverse events on patients with COVID-19. 5-day remdesivir had the similar clinical effectiveness and mortality with 10-day remdesivir, and had lower serious adverse events rate. Comprehensive considering the cost and benefit, 5-day remdesivir may be a better therapeutic option if available medical resources are limited.

Background: Accumulating evidence suggests that coronavirus disease 2019 (COVID-19) is associated with hypercoagulative status, particularly for critically ill patients in the intensive care unit. However, the prevalence of venous thromboembolism (VTE) in these patients under routine prophylactic anticoagulation remains unknown. A meta-analysis was performed to evaluate the prevalence of VTE in these patients by pooling the results of these observational studies.Methods: Observational studies that reported the prevalence of VTE in critically ill patients with COVID-19 were identified by searching the PubMed and Embase databases. A random-effect model was used to pool the results by incorporating the potential heterogeneity.Results: A total of 19 studies with 1,599 patients were included. The pooled results revealed that the prevalence of VTE, deep venous thrombosis (DVT), and pulmonary embolism (PE) in critically ill patients with COVID-19 was 28.4% [95% confidence interval (CI): 20.0–36.8%], 25.6% (95% CI: 17.8–33.4%), and 16.4% (95% CI: 10.1–22.7%), respectively. Limited to studies, in which all patients received routine prophylactic anticoagulation, and the prevalence for VTE, DVT, and PE was 30.1% (95% CI: 19.4–40.8%), 27.2% (95% CI: 16.5–37.9%), and 18.3% (95% CI: 9.8%−26.7%), respectively. The prevalence of DVT was higher in studies with routine screening for all patients, when compared to studies with screening only in clinically suspected patients (47.5% vs. 15.1%, P < 0.001).Conclusion: Critically ill patients with COVID-19 have a high prevalence of VTE, despite the use of present routine prophylactic anticoagulation.

This meta-analysis study examined perceived parental differences between Chinese mothers and fathers from the perspective of adolescents. A systematic search for relevant articles published up to 2019 was performed in electronic databases. The random-effect model was used to calculate the weighted and pooled effect size at the 95% confidence interval. This study was based on 43 studies in English peer-reviewed journals involving 55,759 Chinese adolescents aged between 11 and 18 years. We conducted subgroup analyses to explore whether differences in study designs (i.e., cross-sectional and longitudinal) and adolescent gender could explain perceived parental differences. The results showed that perceived maternal parenting attributes were more positive than perceived paternal parenting attributes in cross-sectional and longitudinal studies. Besides, perceived paternal parenting attributes showed slightly greater variability than did maternal parenting attributes. Subgroup analysis based on adolescent gender revealed that only adolescent girls perceived maternal parenting attributes to be more positive than paternal parenting attributes.

AbstractObjective. To evaluate the clinical effects of piribedil in adjuvant treatment of Parkinson’s Disease (PD) by pooling previously openly published studies. Methods. The related electronic databases of Medline (1960~2017.5), Cochrane central register of controlled trials (CENTRAL), EMBASE (1980~2017.5) and Wanfang (1986~20175.5) were searched by two reviewers (Lu Peihua and Wang Jianqian) independently for publications including the topic of prospective randomized controlled trials about clinical effects of piribedil in adjuvant treatment of PD. The data of each included study was extracted and pooled by Stata11.0 software (for meta-analysis). The statistical heterogeneity across the studies was evaluated by I2 test and the publication bias was calculated by begg’s funnel plot and Egger’s line regression test. Results. After searching the related electronic databases of Medline, CENTRAL, EMBSE and Wanfang databases, 11 clinical studies were included in this meta-analysis. The pooled RR (random effect model) of clinical efficacy was 1.29 (95%CI:1.18~1.41, P=4×10-3) indicating the clinical efficacy of piribedil group was signficat higher than those of control group. The standard mean difference (SMD) for UPDRS score changed before and after treatment was pooled by random effect model. The combined SMD was -0.41 (95%CI:-0.75~-0.06). For piribedil related side effects, the combined data indicated that there was no statistical difference for nausea and vomiting (RR=0.43, 95%CI:0.41~1.69, P=0.61), mental disorders (RR=0.85, 95%CI:0.45~1.59, P=0.61) and other toxicities (RR=0.32, 95%CI:0.09~1.16, P=0.08). Conclusion. Piribedil combined with Levodopa in adjuvant treatment of PD is more effective than Levodopa alone without increasing the drug related toxicity.

Background: To systematically review the literature about the effect of systemic corticosteroid therapy (CST) on outcomes of COVID-19 patients. Methods: We searched Medline, Embase, EBM Reviews, Scopus, Web of Science, and preprints up to July 20, 2020. We included observational studies and randomized controlled trials (RCT) that assessed COVID-19 patients treated with CST. We pooled adjusted effect estimates of mortality and other outcomes using a random effect model, among studies at low or moderate risk for bias. We assessed the certainty of evidence for each outcome using the GRADE approach. Results: Out of 1067 citations screened for eligibility, one RCT and 19 cohort studies were included (16,977 hospitalized patients). Ten studies (1 RCT and 9 cohorts) with 10,278 patients examined the effect of CST on short term mortality. The pooled adjusted RR was 0.92 (95% CI 0.69-1.22, I2=81.94 %). This effect was observed across all stages of disease severity. Four cohort studies examined the effect of CST on composite outcome of death, ICU admission and mechanical ventilation need. The pooled adjusted RR was 0.41(0.23-0.73, I2=78.69%). Six cohort studies examined the effect of CST on delayed viral clearance. The pooled adjusted RR was 1.47(95% CI 1.11-1.93, I2=43.38%). Conclusion: Heterogeneous and low certainty cumulative evidence suggests that CST lacks efficacy in reducing short-term mortality while possibly delaying viral clearance in patients hospitalized with COVID-19. Because of the discordant results between the single RCT and observational studies, more research should continue to identify the clinical and biochemical characteristics of patients population that could benefit from CST.

Balance problems are one of the most frequent symptoms in patients with Fibromyalgia Syndrome (FMS). However, the extent and nature of this balance disorder are not known. The objective of this work was to determine the best evidence for the alteration of postural balance in patients with FMS and analyze differences with healthy controls. To meet this objective, a systematic review with meta-analysis was performed. A bibliographical search was carried out in PubMed Medline, Scopus, Web of Science, CINAHL and SciELO. Observational studies that assessed postural balance in patients with FMS compared to healthy subjects in baseline conditions, were selected. In a random-effect model, the pooled effect was calculated with the Standardized Mean Difference (SMD) and its 95% confidence interval (CI). Nineteen studies reporting data of 2347 participants (95% female) were included. FMS patients showed poor balance with a large effect on static (SMD = 1.578; 95% CI = 1.164, 1.992), dynamic (SMD = 0.946; 95% CI = 0.598, 1.294), functional balance (SMD = 1.138; 95% CI = 0.689, 1.588) and on balance confidence (SMD = 1.194; 95% CI = 0.914, 1.473). Analysis of the Sensory Organization Test showed large alteration of vestibular (SMD = 1.631; 95% CI = 0.467, 2.795) and visual scores (SMD = 1.317; 95% CI = 0.153, 2.481) compared to healthy controls. Patients with FMS showed worse scores for different measures of postural balance compared to healthy controls. Concretely, FMS patients appear to have poor vestibular and visual scores with a possible somatosensory dependence.

Abstract Background Neural tube defects (NTDs) are a group of disorders that arise from the failure of the neural tube close between 21 and 28 days after conception. About 90% of neural tube defects and 95% of death due to these defects occurs in low-income countries. Since these NTDs cause considerable morbidity and mortality, this study aimed to determine the prevalence and associated factors of NTDs in Africa. Methods The protocol of this study was registered in the International Prospective Register of Systematic Reviews (PROSPERO number: CRD42020149356). All major databases such as PubMed/MEDLINE, EMBASE, CINAHL, Web of Science, African Journals Online (AJOL), and Google Scholar search engine were systematically searched. A random-effect model was used to estimate the pooled prevalence of NTDs in Africa, and Cochran’s Q-statistics and I2 tests were used to assess heterogeneity between included studies. Publication bias was assessed using Begg ’s tests, and the association between determinant factors and NTDs was estimated using a random-effect model. Results Of the total 2679 articles, 37 articles fulfilled the inclusion criteria and were included in this systematic review and meta-analysis. The pooled prevalence of NTDs in Africa was 50.71 per 10,000 births (95% CI: 48.03, 53.44). Folic acid supplementation (AOR: 0.40; 95% CI: 0.19–0.85), maternal exposure to pesticide (AOR: 3.29; 95% CI: 1.04–10.39), mothers with a previous history of stillbirth (AOR: 3.35, 95% CI: 1.99–5.65) and maternal exposure to x-ray radiation (AOR 2.34; 95% CI: 1.27–4.31) were found to be determinants of NTDs. Conclusions The pooled prevalence of NTDs in Africa was found to be high. Maternal exposure to pesticides and x-ray radiation were significantly associated with NTDs. Folic acid supplementation before and within the first month of pregnancy was found to be a protective factor for NTDs.

ObjectivesThis meta-analysis aims to (1) evaluate the efficacy of physical activity interventions in heart failure and (2) to identify intervention characteristics significantly associated with the interventions’ efficacy.MethodsRandomised controlled trials reporting intervention effects on physical activity in heart failure were combined in a meta-analysis using a random-effect model. Exploratory meta-analysis was performed by specifying the general approach (eg, cardiac rehabilitation), strategies used (eg, action planning), setting (eg, centre based), mode of delivery (eg, face to face or online), facilitator (eg, nurse), contact time and behavioural change theory use as predictors in the random-effect model.ResultsInterventions (n=21) had a significant overall effect (SMD=0.54, 95% CI (0.13 to 0.95), p<0.0005). Combining an exercise programme with behavioural change intervention was found efficacious (SMD=1.26, 95% CI (0.26 to 2.26), p<0.05). Centre-based (SMD=0.98, 95% CI (0.35 to 1.62), and group-based (SMD=0.89, 95% CI (0.29 to 1.50),) delivery by a physiotherapist (SMD=0.84, 95% CI (0.03 to 1.65),) were significantly associated with efficacy. The following strategies were identified efficacious: prompts/cues (SMD=3.29, 95% CI (1.97 to 4.62)), credible source (standardised mean difference, SMD=2.08, 95% CI (0.95;3.22)), adding objects to the environment (SMD=1.47, 95% CI (0.41 to 2.53)), generalisation of the target behaviour SMD=1.32, 95% CI (0.22 to 2.41)), monitoring of behaviour by others without feedback (SMD=1.02, 95% CI (0.05 to 1.98)), self-monitoring of outcome(s) of behaviour (SMD=0.79, 95% CI (0.06 to 1.52), graded tasks (SMD=0.73, 95% CI (0.22 to 1.24)), behavioural practice/rehearsal (SMD=0.72, 95% CI (0.26 to 1.18)), action planning (SMD=0.62, 95% CI (0.03 to 1.21)) and goal setting (behaviour) (SMD=0.56, 95% CI (0.03 to 1.08)).ConclusionThe meta-analysis suggests intervention characteristics that may be suitable for promoting physical activity in heart failure. There is moderate evidence in support of an exercise programme combined with a behavioural change intervention delivered by a physiotherapist in a group-based and centre-based settings.PROSPERO registerationCRD42015015280.

AimLeptin, synthesised by adipocytes, has been identified as a hormone that can influence inflammatory activity. Several studies have investigated leptin levels in patients with multiple sclerosis (MS), but the results are not consistent. This study aims to derive a more precise evaluation on the relationship between circulating leptin levels and MS.DesignA comprehensive literature searched up to July 2017 was conducted to evaluate the association of circulating leptin levels and MS. The random-effect model was applied to calculate pooled standardised mean difference (SMD) and its 95% CI.Main outcome measuresCirculating leptin levels of patients with MS and healthy controls.ResultsOf 2155 studies identified, 33 met eligibility criteria and 9 studies with 645 patients with MS and 586 controls were finally included in the meta-analysis. Meta-analysis revealed that, compared with the healthy control group, the MS group had significantly higher plasma/serum leptin levels, with the SMD of 0.70% and 95% CI (0.24 to 1.15). Subgroup analyses suggested that the leptin levels of patients with MS were associated with region, age, study sample size, measurement type, gender and blood sample type.ConclusionOverall, our study suggests that patients with MS have a significantly higher leptin level than in healthy controls. Further mechanism studies and longitudinal large cohort studies are still needed to further reveal the role of leptin in the pathogenesis of MS.
