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.

Introduction: Prevalence of hypertension (HTN) is increasing in the developing countries like Iran. Various studies have reported different rates of HTN in Iran. The purpose of this study was to estimate an overall prevalence of HTN in Iran. Methodology: Using the English and Persian key derived from Mesh, the databases including MagIran, Iran Medex, SID, Web of Sciences, PubMed, Science Direct and Google Scholar as a searching engine were reviewed: from 2004 to 2018. The overall prevalence of MA was estimated using Random effect model. The I2 test was used to assess the heterogeneity of the studies. Additionally, the quality of studies was evaluated using a standard tool. Publication bias was conducted with the Egger test. Meta-regression and analysis of subgroups were analyzed based on variables such as age, marital status, region and tools. Data were analyzed using STATA 12 software. Results: Analysis of 58 primary articles with a sample size of 902580 showed that the prevalence of HTN in Iran was 25% (with 95% CI of 22-28). The highest prevalence of HTN was related to elderly (42%). The prevalence of HTN was 25% (95% CI: 19-31) in women and 24% (95% CI: 20-28) in men with no significant difference (p = 0.758). The results also indicated that the prevalence of HTN was not related to the year of studies (p = 0.708) or sample size (p = 769). Conclusion: Despite the advancements in science and technology, along with health and prevention of diseases, the overall prevalence of HTN raised in Iran. Since HTN is a silent disease with significant health consequences and economic burden, programs designed to better HTN control seem vital to enhance community health.

Abstract Background Globally, PUs are recognized as one of the five most frequent causes of harm to clients. With millions affected globally, the national pooled prevalence of pressure ulcers in Ethiopia remains unknown. Hence, this review and meta-analysis aimed to determine the prevalence of pressure ulcers among hospitalized clients in Ethiopia. Methods Studies were retrieved through search engines in PubMed, Scopus, WHO Afro Library, Google Scholar, Africa Journals Online, and Web of Science. Heterogeneity between-studies were checked using the I2 test. A funnel plot and Egger’s regression test was used to assess the presence of publication bias. The random-effect model was fitted to estimate summary effects and 95% confidence intervals (CIs) across studies. The analyses were performed using STATA™ Version 14 software. Results The pooled prevalence of pressure ulcer in Ethiopia was assessed using seven studies involving a total of 1881 participants. The pooled prevalence of pressure ulcers in Ethiopia was 11.7% (95% CI: 7.28, 16.13). The subgroup analysis showed that the estimated magnitude of pressure ulcers was 15.89% (95% CI: 13.32, 18.46); among studies, their sample size was greater than or equal to 250. Conclusion The current review reported that the pooled prevalence of pressure ulcers in Ethiopia was relatively high. Hence, policymaker and healthcare providers should give attention to reduce the magnitude of pressure ulcers. Furthermore, further a meta-analysis study could be conducted to identify individual and health care service-related factors related to the occurrence of pressure ulcers.

Objective : The present study aims to examine childbirth self-efficacy levels with potential moderating variables. Methods: The systematic searches were conducted in nine databases in July 2019. The PRISMA checklist was used. The quality of studies was evaluated by two researchers. The random-effect model was used in the present meta-analysis. The heterogeneity tests and moderator analyses were performed. There were 18 eligible articles. Results: Results indicated that childbirth self-efficacy levels do not change based on parity (Q=0.784, p=0.376 for efficacy expectancy, Q=0.190, p=0.663 for outcome expectancy). The between-study variance was not significant for subdimensions of CBSEI (Qb = 1.531, p = .216), which means no significant difference between OE and EE levels was found. The between-study variance was not significant for OE levels (Qb = 0.333, p = .847), which means no significant difference was found between Outcome-AL, Outcome-SS, and OE-16. The moderator analysis, including Efficacy-AL, Efficacy-SS, and EE-16 presented a higher pooled mean score for EE-16 (111.56; 95% CI = 98.66 to 124.46). However, the between-study variance was not significant for EE levels (Qb = 4.240, p = .120). Despite the moderator analysis, the finding of high heterogeneity suggests the need for further studies which examine the concept of childbirth self-efficacy with additional variables. Conclusion: The study presents that childbirth self-efficacy levels do not change based on parity, stages of labor and subdimensions of CBSEI. Researchers need to examine the concept of childbirth self-efficacy with new variables for further clarify of concept.

Co-infection with malaria and chikungunya (CHIKV) could exert a significant public health impact with infection misdiagnosis. Therefore, this study aimed to collect qualitative and quantitative evidence of malaria and CHIKV co-infection among febrile patients. Methods: Potentially relevant studies were identified using PubMed, Web of Science, and Scopus. The bias risk of the included studies was assessed using the checklist for analytical cross-sectional studies developed by the Joanna Briggs Institute. The pooled prevalence of malaria and CHIKV co-infection among febrile patients and the pooled prevalence of CHIKV infection among malaria patients were estimated with the random effect model. The odds of malaria and CHIKV co-infection among febrile patients were also estimated using a random effect model that presumed the heterogeneity of the outcomes of the included studies. The heterogeneity among the included studies was assessed using the Cochran Q test and I2 statistics. Publication bias was assessed using the funnel plot and Egger’s test. Results: Of the 1924 studies that were identified from the three databases, 10 fulfilled the eligibility criteria and were included in our study. The pooled prevalence of malaria and CHIKV co-infection (182 cases) among febrile patients (16,787 cases), stratified by diagnostic tests for CHIKV, was 10% (95% confidence interval (CI): 8–11%, I2: 99.5%) using RDT (IgM), 7% (95% CI: 4–10%) using the plaque reduction neutralization test (PRNT), 1% (95% CI: 0–2%, I2: 41.5%) using IgM and IgG ELISA, and 4% (95% CI: 2–6%) using real-time RT-PCR. When the prevalence was stratified by country, the prevalence of co-infection was 7% (95% CI: 5–10%, I2: 99.5%) in Nigeria, 1% (95% CI: 0–2%, I2: 99.5%) in Tanzania, 10% (95% CI: 8–11%) in Sierra Leone, 1% (95% CI: 0–4%) in Mozambique, and 4% (95% CI: 2–6%) in Kenya. The pooled prevalence of CHIKV infection (182 cases) among malaria patients (8317 cases), stratified by diagnostic tests for CHIKV, was 39% (95% CI: 34–44%, I2: 99.7%) using RDT (IgM), 43% (95% CI: 30–57%) using PRNT, 5% (95% CI: 3–7%, I2: 5.18%) using IgM and IgG ELISA, and 9% (95% CI: 6–15%) using real-time RT-PCR. The meta-analysis showed that malaria and CHIKV co-infection occurred by chance (p: 0.59, OR: 0.32, 95% CI: 0.6–1.07, I2: 78.5%). Conclusions: The prevalence of malaria and CHIKV co-infection varied from 0% to 10% as per the diagnostic test for CHIKV infection or the country where the co-infection was reported. Hence, the clinicians who diagnose patients with malaria infections in areas where two diseases are endemic should further investigate for CHIKV co-infection to prevent misdiagnosis or delayed treatment of concurrent infection.

Background: Pancreatitis is considered as the most prevalent serious disorders of endoscopic retrograde cholangiopancreatography (ERCP). Different approaches have been suggested to prevent or reduce this complication. Therefore we aim to investigate them in the current study. This systematic review was performed in 2019 using Pubmed, Embase, google scholar and Cochrane library. Two reviewers selected eligible studies and outcomes of interest were extracted. Meta-analysis was done by using the random or fixed-effect models. I-square statistic test was used for heterogeneity analysis. Material and Methods: Totally, 2758 articles were searched. Thereafter duplicated and irrelevant articles were excluded, and six articles were entered to the present study. Six RCTs were considered eligible with a total participants of 1685. Results: The relative risk of PEP was not significantly different in NSAID and hydration groups (Pooled RR=1.19, 95%CI: 0.40 to 3.50, P-value=0.74). The random effect model indicated no significant differences between NSAID and NSAID+hydration groups regarding the incidence of PEP (Pooled RR=2.19, 95%CI: 0.70 to 6.88, P-value=0.17). Conclusion: Additionally, the results of one study showed that rectal indomethacin alone appeared to be more effective for preventing PEP than no prophylaxis, PSP alone, and the combination of indomethacin and PSP. Using NSAIDs alone or the combination of NSAIDs and hydration can reduce the risk of post-ERCP pancreatitis. Lack of studies comparing different approaches of prophylaxis in post-ERCP patient or the reporting of different parameters among the existing studies seriously limited the possibility and quality of meta-analysis. Further well-designed studies with accurate reporting of data is necessary to provide more reliable conclusion.

Background: The COVID-19 affected millions of people, and the patients present a constellation of symptoms and comorbidities. We aimed to estimate the prevalence of reported symptoms and comorbidities and assess the correlation between a series of symptoms and comorbidities and age of the patients' positive in COVID-19. Methods: We performed a systematic review and meta-analysis [PROSPERO registration: CRD42020182677]. Databases [PubMed, SCOPUS, EMBASE, WHO, Semantic Scholar, and COVID-19 Primer] were searched for clinical studies published from January to April 2020. The pooled prevalence of symptoms and comorbidities were identified using the random effect model, and the multivariable factor analysis was performed to show the correlation between a group of symptoms and comorbidities and age of the COVID-19 patients. Findings: Twenty-nine articles [China (24); Outside of China (5)], with 4,884 COVID-19 patients were included in this study. The meta-analysis investigated 33 symptoms, where fever [84%], cough/dry cough [61%], and fatigue/weakness [42%] were found more prevalent. Out of 43 comorbidities investigated, acute respiratory distress syndrome (ARDS) [61%], hypertension [23%] and diabetes [12%] were the most prevalent comorbid condition. The multivariable factor analysis showed positive association between a group of symptoms and comorbidities, and with the patients' age. For example, the symptoms comprising fever, dyspnea/shortness of breath, nausea, vomiting, abdominal pain, dizziness, anorexia and pharyngalgia; and the comorbidities including diabetes, hypertension, coronary heart disease, COPD/lung disease and ARDS were positively correlated with the COVID-19 patient's age. Interpretation: Among 19 symptoms and 11 comorbidities investigated, a group of symptoms and comorbidities were found correlated with the patients infected in COVID-19.

Objectives: To improve the knowledge on Coronavirus Disease (COVID-19) infection, we aimed to study the prevalence of gastrointestinal symptoms and the dynamics of liver enzymes in children infected with COVID-19. Methods: We performed a systematic search of all the articles published up to May 2020 in the following databases: PubMed-MEDLINE, Scopus, and Cochrane. We chose the fixed- or random-effect model for analysis based on the I2 statistic. The included data were analyzed to identify the prevalence of gastrointestinal symptoms (diarrhea, vomiting or nausea) and to identify the dynamics of liver enzymes in children and adolescents diagnosed with COVID-19. Results: We detected an overall prevalence of all gastrointestinal symptoms of 26% (95% CI: 0.18 - 0.35). The pooled prevalence of diarrhea and nausea/vomiting was 12% (95% CI: 0.08 - 0.16) with no heterogeneity (P = 0.19; I2 = 23.53%) and 11% (95% CI: 0.05 - 0.17), respectively. The pooled prevalence of elevated ALT and AST and LDH was 12% (95% CI: 0.07 - 0.17), 14% (95% CI: 0.10 - 0.18) and 33% (95% CI: 0.12 - 0.54), respectively among the included studies. Conclusions: According to our systematic review and meta-analysis, 26% of the children and adolescents diagnosed with COVID-19 present gastrointestinal symptoms. This paper has provided a comprehensive overview of the prevalence of digestive symptoms of COVID-19 and of the liver enzymes dynamics in children and adolescents.

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.

<b><i>Background:</i></b> Mild cognitive impairment (MCI) induced the majority number of dementia patients. The prevalence of MCI in China varied across studies with different screening tools and diagnostic criteria. <b><i>Objective:</i></b> A systematic review and meta-analysis was conducted to estimate the pooled MCI prevalence among the population aged 55 years and older in China. <b><i>Methods:</i></b> PubMed, EMBASE, CNKI, Wanfang, CQVIP, and CBMdisc were searched for studies on prevalence of MCI among Chinese elderly between January 1, 1980, and February 10, 2020. The quality assessment was conducted via external validity, internal validity, and informativity, the pooled prevalence was calculated through the random-effect model, and the homogeneity was evaluated by Cochran’s <i>Q</i> test and <i>I</i><sup>2</sup>. <b><i>Results:</i></b> Fifty-three studies with 123,766 subjects were included. The pooled prevalence of MCI among Chinese elderly was 15.4% (95% CI: 13.5–17.4%). Subgroup analyses indicated that the prevalence calculated with different screening tools was 20.2% (95% CI: 15.1–25.9%) for Montreal Cognitive Assessment (MoCA) and 13.0% (95% CI: 10.7–15.5%) for Mini-Mental State Examination (MMSE). According to different diagnostic criteria, the prevalence was 14.8% (95% CI: 12.2–17.6%) for Petersen criteria, 15.0% (95% CI: 12.7–17.5%) for DSM-IV, and 21.2% (95% CI: 17.5–25.2%) for Chinese Expert Consensus on Cognitive Impairment (CECCI). Besides, women, older adults, illiterate people, rural residents, and those who lived with unhealthy lifestyles and morbidity showed higher prevalence. <b><i>Conclusions:</i></b> The prevalence of MCI in China was 15.4%, which varied by demographics, lifestyles, morbidity, screening tools, and diagnostic criteria. In further studies, screening tools and diagnosis criteria should be considered when estimating MCI prevalence.
