Effect of Listening to Music on Wingate Anaerobic Test Performance. A Systematic Review and Meta-Analysis

Background: There are many athletes who like to listen to music while making a high intensity effort. However, research into the effects of listening to music on athletic performance has provided controversial results, and it is suggested that the timing and type of music might affect the anaerobic performance response. Purpose: The main aim of the current systematic review and meta-analysis was to analyze the effects while listening to music tasks via the 30 s Wingate anaerobic test (WAnT) on absolute performance and relative peak power (APP and RPP), absolute and relative mean power (AMP and RMP), and fatigue index (FI). Methods: PRISMA guidelines were used as a basis for conducting this systematic review, with inclusion criteria being set out according to the PICOS model. Computer-based literature research was undertaken until 10 March 2020 using the following online databases: PubMed/Medline, WOS, Cochrane Library, and Scopus. The literature was reviewed with regard to the effects of listening to music on the WAnT using several music variables on: APP, RPP, AMP, RMP and FI. Hedges’ g formula was used to calculate both standard mean differences and 95% confidence intervals, in order to establish continuous outcomes. Furthermore, the I2 statistic evaluated systematic differences (heterogeneity) together with a random effect meta-analysis model. Results: This systematic review included nine articles that researched into the effects of music on WAnT performance (six studies describe improvements in APP and/or RPP, four in AMP and/or RMP and three in FI). The random effects model was used to undertake a final meta-analysis, with standardized mean differences (SMD) and magnitude of standardized mean differences (MSMD) (Hedges’ g) being pooled accordingly. The resulting meta-analysis incorporated eight studies that had been previously published, with results showing that there were no apparent beneficial effects on APP (p = 0.09), AMP (p = 0.33) and FI (p = 0.46) as a consequence of listening to music. However, listening to music showed beneficial effects on RPP (SMD: 0.65; 95%: CI 0.35 to 0.96; MSMD: moderate; I2, 0%; p < 0.001) and RMP (SMD: 1.03; 95%: CI, 0.63 to 1.42; MSMD: trivial; I2, 0%; p < 0.001). Conclusion: This systematic review and meta-analysis has shown that listening to music during the WAnT might physiologically enhance relative anaerobic exercise performance, although reasons remain speculative.

Cashew Nut

Introduction: Nuts are one of the dietary components which appear to have beneficial effects on cardiovascular disease biomarkers. Studies demonstrate beneficial effects of cashews on serum lipids concentration, but results in the literature remain inconclusive. We conducted a review to examine the effects of cashew nut supplementation on serum lipid profile. Methods: Two reviewers independently searched PubMed, Web of Science, Cochrane Library, Scopus, and EMBASE electronic databases from inception until June 2019 without language limitation. Random- and fixed-effects models were used to calculate 95% confidence intervals (CI) for studies. Results: Six randomized clinical trials comprising 531 participants were included in this systematic review. Three studies were included in the meta-analysis model. There were no significant changes for total cholesterol (TC) (standardized mean difference [SMD]: –0.02, 95% CI: –0.32, 0.28), triglycerides (TG) (SMD: –0.01, 95% CI: –0.22, 0.20), high-density lipoprotein (HDL) cholesterol (SMD: 0.09, 95% CI: –0.16, 0.34), or low-density lipoprotein (LDL) cholesterol (SMD: –0.18, 95% CI: –0.75, 0.39). Conclusion: The results of this analysis demonstrate that treatment with cashew nut supplementation alone did not significantly change serum levels of LDL, HDL, TC, or TG.

AbstractAnencephaly is a severe anomaly of the brain that results from the failure of the cephalic part of the neural tube to close during the fourth week. It occurs at least in one per thousand births and is the major cause of fetal loss and disabilities in newborns. The objective of this review is to determine the birth prevalence of anencephaly in Africa. We identified relevant studies via a search of databases like PubMed Central, PubMed/Medline, Science Direct, Joanna Briggs Institute, African Journals Online, Embase, Google Scholar, Web of Science, and Cochrane Library. After examining the heterogeneity of studies via the Cochran Q test and I2 test (and Forest plot for visual inspection), the prevalence of anencephaly was estimated using the random-effect meta-analysis model. Consequently, we carried out subgroup, sensitivity, meta-regression, trim and fill, time-trend, and meta-cumulative analyses. In this systematic review and meta-analysis, the twenty-four studies reported a total of 4,963,266 births. The pooled birth prevalence of anencephaly in Africa was 0.14% (95% CI: 0.12, 0.15%). Higher burden of anencephaly was detected in Ethiopia (0.37%, CI: 0.15, 0.58%), Algeria (0.24%, CI: 0.24, 0.25%), and Eritrea (0.19%, CI: 0.19, 0.19%). The higher pooled prevalence of anencephaly was observed in the studies that included both live births and stillbirths (0.16%) and in studies done after the year 2010 (0.25%) whereas, the lower burden was detected among countries that had a mandatory folic acid fortification (0.05%). High birth prevalence of anencephaly was detected in Africa. Strong prevention and control measures should be the priority because of an increment in the magnitude of anencephaly. Helping in prevention programs, which should be the ultimate contribution of this study to the field.

ObjectiveTo identify the birth prevalence of encephalocele in Africa, 2020.MethodsWe carried out a systematic search of the following databases (PubMed/Medline, PubMed Central, Joanna Briggs Institute (JBI) Library, Cochrane Library, Web of Science, Google Scholar, Science Direct, African Journals Online and Embase), using search terms (prevalence, encephalocele, “neural tube defects”, “cranium bifidum”, “congenital malformations”, “congenital defects”, “structural birth defects”, “structural abnormalities”, newborns/neonates/ “live births”/ “stillbirths” and their MeSH Terms) up to 16 July 2021. The JBI quality appraisal checklist was used to assess the quality of studies when they were abstracted using a standardised data extraction template. The I2 statistic and Cochrane Q test were used to examine heterogeneity across studies statistically. The prevalence of encephalocele was estimated using a random-effect meta-analysis model. Subgroup, sensitivity, meta-regression and time trend analysis were carried out. The publication bias was checked using Egger and Begg’s tests.ResultsTwenty-seven relevant studies were identified and provided a total of 5 107 109 births. In this systematic review and meta-analysis, the pooled birth prevalence of encephalocele in Africa was 0.02% (or 2 per 10 000 births) (95% CI 0.02% to 0.03%). The overall prevalence of birth encephalocele using the median from studies was 0.02% (IQR=0.01%–0.04%). Higher prevalence of encephalocele was detected in Nigeria 0.06% (95% CI 0.04% to 0.08%), Sudan 0.04% (95% CI 0.03% to 0.05%), Egypt 0.04% (95% CI 0.04% to 0.05%), DR of Congo 0.02% (95% CI 0.02% to 0.03%), Ethiopia 0.02% (95% CI −0.004% to 0.05%) and Tanzania 0.02% (95% CI 0.002% to 0.04%). The prevalence of encephalocele per live birth was 0.03% and both live birth and stillbirth was 0.03%.ConclusionsThis review indicates a high prevalence of encephalocele, but studies were limited suggesting the need for additional research.PROSPERO registration numberCRD42021242161.

Abstract Background Trachoma is the commonest infectious cause of blindness. It is prevalent in areas where personal and community hygiene is poor, and it mainly affects deprived and marginalized communities most importantly in Ethiopia. Hence, the aim of this study was to determine the prevalence and associated factors of active trachoma among children in Ethiopia. Method A systematic review and meta-analysis was employed to determine the prevalence of active trachoma and associated factors among children in Ethiopia. We searched databases, including PubMed, Google Scholar, Science Direct, EMBASE and Cochrane Library. To estimate the prevalence, studies reporting the prevalence of active trachoma and its associated factors were included. Data were extracted using a standardized data extraction format prepared in Microsoft excel and the analysis was done using STATA 14 statistical software. To assess heterogeneity, the Cochrane Q test statistics and I2 test were used. Since the included studies revealed considerable heterogeneity, a random effect meta- analysis model was used to estimate the pooled prevalence of active trachoma. Moreover, the association between factors and active trachoma were examined. Results The result of 30 eligible studies showed that the overall prevalence of active trachoma among children in Ethiopia was 26.9% (95% CI: 22.7, 31.0%). In the subgroup analysis, while the highest prevalence was reported in SNNP (35.8%; 95% CI: 22.7, 48.8), the lowest prevalence was reported in Oromia region (20.2%; 95% CI: 12.2, 28.2). Absence of latrine: OR 6.0 (95% CI 2.0, 17.5), the unclean faces of children: OR 5.5 (95% CI 2.8, 10.9), and no reported use of soap for washing: OR 3.3 (95% CI 1.8, 6.0) have shown a positive association with active trachoma among children. Conclusion From this review, it has been concluded that active trachoma among children is still a public health problem in different districts of Ethiopia. The prevalence of almost all studies are significantly higher than WHO target for elimination. Absence of latrine, unclean faces of children, no reported use of soap for washing are the important factors associated with active trachoma among children.

Abstract Background: Postpartum hemorrhage or postpartum bleeding (PPH) is often defined as loss of > 500 ml of blood after vaginal delivery or > 1,000 ml after cesarean delivery within 24 hrs. Postpartum hemorrhage is a leading direct cause of maternal morbidity and mortality in Ethiopia. Therefore, the main objective of this systematic review and meta-analysis was to estimate the pooled magnitude of postpartum hemorrhage and the pooled effect size of the associated factors in Ethiopia.Methods: Primary studies were searched in PubMed / MEDLINE online, Science Direct and Hinari Cochrane Library, CINAHL, African Journals Online databases, Google and Google Scholars. The search for studies was not limited by time and all articles up to October 10/2021 were included. The data extraction format was prepared in Microsoft Excel. The data extracted from the Microsoft Excel format was exported to Stata Version 16.0 statistical software for analysis. A random effect meta-analysis model was used. Statistical heterogeneity was evaluated by the I2 test and Egger's weighted regression test was used to assess publication bias.Result: A total of 165 records from the electronic databases were excluded, but 145 records were excluded for different reasons, and finally 20 studies were included in this final analysis. The pooled magnitude of postpartum hemorrhage in Ethiopia was 8.18% [(95% CI; 6.996 - 9.363]. Older age [OR= 5.038 (95% CI; 2.774 - 9.151)], prolonged labor [OR = 4.054 (95% CI; 1.484 - 11.074)], absence of ANC visit [OR = 13.84 (95% CI; 5.57 - 34.346)] grand-multiparty, [OR = 6.584 (95% CI; 1.902 - 22.795)], and history of postpartum hemorrhage [OR = 4.355 (95% CI; 2.347 - 8.079)] were identified as factors for the occurrence of postpartum hemorrhage.Conclusions: This study concludes that the magnitude of postpartum hemorrhage in Ethiopia was moderately high. The finding was strongly help different stakeholder working in maternal and child health to focus on the main contributors factors to reduce PPH. Health professionals attending delivery should emphasize high-risk groups of mothers. Encouraging ANC visit and prevent prolonged labor should be recommended to reduce the occurrence of postpartum hemorrhage.

Objective The current systematic review aimed to provide comprehensive data on the effects of iodine supplementation in pregnancy and investigate its potential benefits on infant growth parameters and neurocognitive development using meta-analysis. Methods A systematic review was conducted on trials published from January 1989 to December 2019 by searching MEDLINE, Web of Science, the Cochrane Library, Scopus, and Google Scholar. For most maternal and neonatal outcomes, a narrative synthesis of the data was performed. For birth anthropometric measurements and infant neurocognitive outcomes, the pooled standardized mean differences (SMDs) with 95% CIs were estimated using fixed/random effect models. Results Fourteen trials were eligible for inclusion in the systematic review, of which five trials were included in the meta-analysis. Although the findings of different thyroid parameters are inconclusive, more consistent evidence showed that iodine supplementation could prevent the increase in thyroglobulin concentration during pregnancy. In the meta-analysis, no differences were found in weight (−0.11 (95% CI: −0.23 to 0.01)), length (−0.06 (95% CI: −0.21 to 0.09)), and head circumference (0.26 (95% CI: −0.35 to 0.88)) at birth, or in cognitive (0.07 (95% CI: −0.07 to 0.20)), language (0.06 (95% CI: −0.22 to 0.35)), and motor (0.07 (95% CI: −0.06 to 0.21)) development during the first 2 years of life in infants between the iodine-supplemented and control groups. Conclusion Iodine supplementation during pregnancy can improve the iodine status in pregnant women and their offspring; however, according to our meta-analysis, there was no evidence of improved growth or neurodevelopmental outcomes in infants of iodine-supplemented mothers.

e21692 Background: Olanzapine is an atypical antipsychotic medication which has shown efficacy in prevention of chemotherapy-induced nausea and vomiting (CINV) in multiple trials. This study aims to investigate the efficacy of Olanzapine to prevent CINV with an up-to-date systematic review and meta-analysis. Methods: A literature search of Ovid MEDLINE, Embase and Cochrane library was performed to identify randomized controlled trials of olanzapine compared to other antiemetic therapy (5HT3 and/or NK1 antagonist with or without steroids) for prevention of CINV in patients age >=18 years up until December 2016. The primary endpoint was no emesis or nausea episodes in acute (0-24hrs), delayed (24-120hrs) and overall (0-120hrs) period in patients receiving highly or moderately emetogenic chemotherapy (HEC or MEC). Statistical analysis was performed using Review Manager (RevMan 5.3). The Mantel–Haenszel method was applied and random effect analysis model was used to calculate risk ratios. Results: From the literature, 12 RCTs met the inclusion criteria. The age range of patients was 18-89 years. Seven trials included only patients who received HEC while 5 trials included patients receiving either HEC or MEC in various proportions. Olanzapine was statistically superior for 5 primary endpoints except for no nausea in acute period (Table 1). In the non-steroids cohort, olanzapine was superior for no emesis in all 3 periods but statistically significant only for delayed period. Conclusions: Olanzapine is superior to other antiemetic therapy for prevention of CINV. It is less expensive and can improve patient’s quality of life and chemotherapy adherence. [Table: see text]

Abstract Background Published studies have shown contradictory results regarding the relationship between somatometric parameters and varicoceles. We performed a systematic review and meta-analysis to investigate the possible effects of age, height, weight, and body mass index (BMI) on the presence and severity of varicoceles. Methods Databases including EMBASE, MEDLINE, PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Web of Science, and Google Scholar were systematically searched to identify relevant articles published up to March 2020. Two researchers independently identified eligible articles and extracted data. Cochran’s Q statistic and I2 statistics were used to assess heterogeneity. Meta-analysis was performed using StataSE 12.0 software (StataCorp LP, USA). Random-effects models were used to obtain the weighted mean differences (WMDs) and 95% confidence intervals (CIs). Publication bias was assessed using Begg’s funnel plot and Egger’s regression test. Results The search strategy produced 272 articles, of which 18 articles were eligible according to the inclusion/exclusion criteria. A total of 56,325 patients with varicocele and 1,334,694 patients without varicocele were included in the meta-analysis to evaluate the effect of somatometric parameters on the presence and severity of varicocele. The overall results demonstrated that the presence of varicoceles was significantly associated with height (WMD = 1.41, 95% CI = 1.07 to 1.74, P < 0.001) and inversely correlated with BMI (WMD = − 1.35, 95% CI = -1.67 to − 1.03, P < 0.001) but not with age (WMD = -0.93, 95% CI = -2.19 to 0.33, P = 0.149) or weight (WMD = 0.24, 95% CI = -2.24 to 2.72, P = 0.850). The severity of varicocele was inversely correlated with increased BMI but not with age. Conclusion The presence of varicoceles was significantly associated with height and inversely correlated with BMI.

AbstractSusceptibility to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the risk of mortality among people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (PLWHA) is largely unknown. PLWHA are unique due to their altered immune system from their history of chronic HIV infection and their use of antiretroviral therapy, some of which have been used experimentally to treat coronavirus disease 2019 (COVID-19). Therefore, we conducted a systematic review and meta-analysis to assess the epidemiology of SARS-COV-2/HIV coinfection and estimate associated mortality from COVID-19 (Prospero Registration ID: CRD42020187980). PubMed, SCOPUS, OVID and Cochrane Library databases, and medRxiv preprint repositories were searched from January 1, 2020, to December 12, 2020. Data were extracted from studies reporting COVID-19 attack and mortality rates in PLWHA compared to their HIV-negative counterparts. Pooled attack and mortality risks were quantified using random-effects models. We identified 22 studies that included 20,982,498 participants across North America, Africa, Europe, and Asia. The median age was 56 years, and 50% were male. HIV-positive persons had a significantly higher risk of SARS-CoV-2 infection [risk ratio (RR) 1.24, 95% CI 1.05–1.46)] and mortality from COVID-19 (RR 1.78, 95% CI 1.21–2.60) than HIV-negative individuals. The beneficial effects of tenofovir and protease-inhibitors in reducing the risk of SARS-CoV-2 infection and death from COVID-19 in PLWHA remain inconclusive. HIV remains a significant risk factor for acquiring SARS-CoV-2 infection and is associated with a higher risk of mortality from COVID-19. In support of the current Centers for Disease Control and Prevention (CDC) guidelines, persons with HIV need priority consideration for the SARS-CoV-2 vaccine.

Background: This study aimed to synthesize the evidence of the effect of practicing Tai Chi on oxidative stress markers (OxSM). Methods: This systematic review and meta-analysis was conducting using the MEDLINE, Cochrane Library, ScienceDirect, Scopus, Epistemonikos, Lilacs, and Ovid databases to identify randomized (RCT) and non-randomized (NRCT) clinical trials that evaluated the Tai Chi effect on OxSM compared to sedentary behavior, walking or yoga. Pooled mean differences (MDs) with 95% confidence intervals (95%CI) were estimated using the inverse variance method to determine the effect of Tai Chi on OxSM. PROSPERO register: CRD42019138362. Results: Five RCT and five NRCT were included. Compared to sedentary behavior, regular Tai Chi practice increases the levels of the enzymes superoxide dismutase (MD = 34.97 U/mL, (95%CI, 9.45 to 60.48), 344 participants) and catalase (MD = 15.63 U/mL, (95%CI, 4.05 to 27.22), 110 participants), as well as reducing the levels of lipoperoxides (MD = −0.02 µmol/L, (95%CI, −0.04 to −0.00), 234 participants). For comparisons with walking or yoga, only one study per activity was identified comparing the effect on OxSM. Conclusions: Regular Tai Chi practice increases the levels of superoxide dismutase and catalase, as well as reducing the levels of lipoperoxides. More studies are necessary to determine the effect of Tai Chi on OxSM when compared to other physical activities.
