Background. The issue of microbial quality and safety of ready-to-eat foods has become a public health concern that needs to be addressed to protect the consumer’s health. Contamination of ready-to-eat foods by enteric pathogens such as Escherichia coli, Salmonella, and Staphylococcus aureus bacteria is associated with potential health risks and can cause foodborne outbreaks. Thus, the systematic review and meta-analysis aimed at determining the overall evidence on the prevalence of microorganisms of public health significance in ready-to-eat foods based on previous studies. Methods. The articles published from 2015 to 2020 were searched from multiple electronic databases such as PubMed, Google Scholar, MEDLINE, CINAHL, Science Direct, Web of Science, and the Directory of Open Access Journals. The JBI critical appraisal tool was applied to the included articles. To determine the heterogeneity among the included articles, I 2 statistics were used while publication bias was evaluated using the visual funnel plot. A Forest plot using the random effect model for meta-analysis was used to estimate the pooled prevalence of E. coli, Salmonella, and S. aureus in ready to eat foods. Results. The pooled prevalence of E. coli, Salmonella, and S. aureus in ready to eat foods was 33.8% (95% CI: 19.9, 51.2; Q   value = 67.080 , I 2 = 89.56 % ), 26.0% (95% CI: 13.8, 43.6%; Q   value = 83.67 , I 2 = 91.63 % ), and 46.3% (95% CI: 24.8, 69.4%, I 2 = 94.9 % ), respectively. Conclusion. The findings show that contamination of ready-to-eat foods with pathogenic microorganisms continues to be a public health risk. Thus, effective food hygiene and safety systems are necessary to protect the health of the consumers and the public as a whole.

IntroductionIn Ethiopia, undernutrition is the common public health concern, swaying the lives of lots of adolescent girls. Its sequelae are not only limited to them, but rather their upcoming offspring are vulnerable too. Even though some studies have been carried out in different parts of the country, the national pooled prevalence and determinants of undernutrition are not known. Therefore, this study is aimed at determining the pooled prevalence and determinants of undernutrition among adolescent girls in Ethiopia.MethodsPublished articles will be retrieved from databases such as Medline and PubMed. Electronic search engines such as Google Scholar and Google will be used. To identify eligible studies, the Joanna Briggs Institute quality appraisal checklists prepared for different study designs will be used. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist will be used to maintain the scientific robustness of the study. The presence of heterogeneity among studies will be examined by forest plot as well as I2heterogeneity test. Potential causes of heterogeneity will be explored by carrying out sensitivity and subgroup analyses. The DerSimonian and Laird random-effects model will be used provided that heterogeneity is observed. Publication bias will be examined by observing funnel plots, and objectively by Egger’s regression test. If the funnel plot is asymmetric and/or Egger’s test was found to be statistically significant (p<0.05), the trim and fill (Duval and Tweedie’s) analysis will be performed. The presence of a statistical association between independent and dependent variables will be declared if the p value is <0.05 with the 95% CI.Ethics and disseminationSince this is a systematic review and meta-analysis, ethical clearance will not be a concern. The results of the study will be published in a peer-reviewed reputable journal and presented at different scientific research conferences.Trial registration numberCRD42018106180.

Background Iodine deficiency is a major public health concern throughout the world. Goiter is the most visible sign of iodine deficiency. In Ethiopia, a study finding regarding the prevalence of goiter among school-age children is inconsistent and highly variable. Objectives To estimate the pooled prevalence of goiter among school-age children in Ethiopia. Methods Three international databases (MEDLINE/Pub-Med, Google Scholar and Science Direct) were systematically searched. Besides, the reference sections of identified articles were searched to increase the chance of detecting missed articles in gray literature. STATA Version 14 statistical software was used to conduct a meta-analysis. The pooled prevalence with a 95% confidence interval was displayed using the forest plot. A random-effect meta-analysis model was used to compute the pooled prevalence, and The Cochrane Q test statistics and I2 test were used to assess the heterogeneity of the studies. Results A total of 14 studies fulfilled the inclusion criteria and included in this systematic review and Meta-analysis, with a total sample size of 26,282. The finding of this systematic review revealed that the pooled prevalence of goiter among school-age children was 42.9% (95% CI: 38.8–46.9). The highest prevalence of goiter (46.7%) was observed in Oromia region and the lowest (26.3%) was observed in Benishangul-Gumuz region. Conclusions This review finding revealed that more than two in five of the school children in Ethiopia suffer from iodine deficiency disorder as manifested by the goiter rate.

Background and objective Loneliness is associated with increased rates of morbidity and mortality, and is a growing public health concern in later life. This study aimed to produce an evidence-based estimate of the prevalence of loneliness amongst older people (aged 60 years and above). Study design and setting Systematic review and random-effects meta-analysis of observational studies from high income countries 2008 to 2020, identified from searches of five electronic databases (Medline, EMBASE, PsychINFO, CINAHL, Proquest Social Sciences Premium Collection). Studies were included if they measured loneliness in an unselected population. Results Thirty-nine studies reported data on 120,000 older people from 29 countries. Thirty-one studies were suitable for meta-analysis. The pooled prevalence estimate of loneliness was 28.5% (95%CI: 23.9% - 33.2%). In twenty-nine studies reporting loneliness severity, the pooled prevalence was 25.9% (95%CI: 21.6% - 30.3%) for moderate loneliness and 7.9% (95%CI: 4.8% - 11.6%) for severe loneliness (z = -6.1, p < 0.001). Similar pooled prevalence estimates were observed for people aged 65–75 years (27.6%, 95%CI: 22.6% - 33.0%) and over 75 years (31.3%, 95%CI: 21.0% - 42.7%, z = 0.64, p = 0.52). Lower levels of loneliness were reported in studies from Northern Europe compared to South and Eastern Europe. Conclusions Loneliness is common amongst older adults affecting approximately one in four in high income countries. There is no evidence of an increase in the prevalence of loneliness with age in the older population. The burden of loneliness is an important public health and social problem, despite severe loneliness being uncommon. PROSPERO registration CRD42017060472.

Abstract Background Vitamin D deficiency among pregnant women is a public health concern globally. In India, individual studies report high prevalence. However, lack of national data masks the true burden. This work determined the pooled prevalence of vitamin D deficiency among pregnant women in India through a systematic review of literature and meta-analysis. Methods Three different search engines yielded 15 eligible articles. Study quality was assessed by 10 different criteria and summary of study quality was categorized as per Cochrane standards. Meta-analysis was performed to estimate pooled prevalence of vitamin D deficiency among healthy pregnant women and heterogeneity among selected studies. A sample of n = 4088 was used to study the pooled prevalence among pregnant women. Results The random effects combined estimate was 32.35% (95% CI, (12.58–117.48). High heterogeneity (tau2 = 0.39, I2 = 100%) and high risk of bias was observed among the selected studies. The test for overall effect was observed to be z = 2.54(P = 0.01). Conclusion Pooled estimate > 30% emphasizes the need for screening through antenatal care services and initiate preventive measures to address the deficiency.

Several coliform species other than Escherichia coli are often associated with and possibly responsible for acute and chronic diarrheal disease. Recent evidence suggests that non-Escherichia coli coliforms may be capable of colonizing the human intestine and producing enterotoxin(s) in high-yield. Whether these organisms are newly capable of causing disease because of infestation with extrachromosomal factors mediating pathogenicity or simply because of inherent pathogenic capabilities that have gone unrecognized, they pose a potential health hazard. Food, medical, and public health microbiologists should be aware that the non-E. coli coliforms contaminating foods may be potential enteropathogens. This possibility may make determination of their pathogenic capabilities even more important than identification of their taxonomic characteristics.

Objective. Syphilis is one of the most imperative STIs, caused by the spirochete Treponema pallidum. During pregnancy it is associated with disastrous health outcomes in the newborn. In sub-Saharan Africa, study findings on the prevalence of syphilis among pregnant women are highly dispersed and inconsistent. The aim of the current review is to conduct a systematic review and meta-analysis of syphilis in sub-Saharan Africa among pregnant women. Design. Systematic review and meta-analysis. Data Sources. Databases including MEDLINE, PubMed, Cochrane Library, Google Scholar, and HINARI and reference lists of previous prevalence studies were systematically searched for relevant literature from January 1999 to November 2018. Results were presented in forest plot, tables, and figures. Random-effects model was used for the meta-analysis. For the purpose of this review, a case of syphilis was defined as positive treponemal or nontreponemal tests among pregnant women. Data Extraction. Our search gave a total of 262 citations from all searched databases. Of these, 44 studies fulfilling the inclusion criteria and comprising 175,546 subjects were finally included. Results. The pooled prevalence of syphilis among pregnant women in sub-Saharan Africa was 2.9% (95%CI: 2.4%-3.4%). East and Southern African regions had a higher syphilis prevalence among pregnant women (3.2%, 95% CI: 2.3%-4.2% and 3.6%, 95%CI: 2.0%-5.1%, respectively) than the sub-Saharan African pooled prevalence. The prevalence of syphilis among pregnant women in most parts of the region seemed to have decreased over the past 20 years except for the East African region. However, prevalence did not significantly differ by region and time period. Conclusion. This review showed a high prevalence of syphilis in sub-Saharan Africa among pregnant women. The evidence suggests strengthening the screening program during pregnancy as part of the care package during antenatal care visits. Programs focusing on primary prevention of syphilis in women should also be strengthened.

Background. Malaria during pregnancy remains a major public health concern in tropical and subtropical countries. Moreover, malaria is increasingly associated with unwanted pregnancy outcomes such as an increased risk of abortion, stillbirth, premature delivery, and low-birthweight infants. Since pregnant women are most vulnerable to malaria, implementation of the appropriate prevention and control measures among this group is very important. Therefore, the current review was designed to assess the prevalence of both symptomatic and asymptomatic malaria among pregnant women in Ethiopia.Method. In this systematic review and meta-analysis we have followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The databases used were PubMed, Google Scholar, HINARI, and Science Direct literature. Search terms used were “prevalence”, “malaria”, “pregnant women”, and “Ethiopia”. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. The meta-analysis was conducted using STATA 14 software. The pooled meta-logistic regression was computed to present the pooled prevalence with a 95% confidence interval (CI).Result. Among a total of 10207 studies, seven studies were included in this analysis. The estimated pooled prevalence of malaria among pregnant women in Ethiopia was 12.72% (95% CI: 7.45, 17.98). In subgroup analysis, the prevalence of malaria showed a significant variation between asymptomatic and symptomatic cases, which was 7.83% (95% CI: 2.23, 13.43) and 17.97% (95% CI: 7.31, 28.92), respectively.Conclusion. The current systematic review and meta-analysis showed that the pooled prevalence of malaria among pregnant women was found to be relatively higher compared with the general population. Therefore, the existing prevention and control measures should be strengthen.

Abstract Background: Malnutrition remains as a major public health problem in the world, particularly in developing countries such as Ethiopia. The prevalence of stunting in Ethiopia has been decreased considerably from 58% in 2000 to 44% in 2011 and 38% in 2016. The aim of this systematic review and meta-analysis is to assess the prevalence of stunting and its associations with wealth index among under-five children in Ethiopia. Methodology: The databases screened were PubMed/MEDLINE, Scopus, HINARI and grey literatures. The studies’ qualities were assessed by two reviewers independently, and any controversy was handled by other reviewers using the JBI critical appraisal checklist. In the statistical analysis, the funnel plot, Egger’s test, and Begg’s test were used to assess publication bias. The I2 statistic, forest plot, and Cochran’s Q test were used to deal with heterogeneity. Results: The pooled prevalence of stunting was 41.5% among under-five children, despite its considerable heterogeneity (I2=97.6%, p<0.001). However, the included studies had no publication bias in calculating the pooled prevalence (Egger’s test p=0.26; Begg’s test p=0.87). Children from households with a medium or low/poor wealth index had higher odds of stunting (AOR 1.33, 95% CI: 1.07, 1.65 or AOR 1.92, 95% CI: 1.46, 2.54, respectively) compared to children from households with a high/rich wealth index. Conclusions: The pooled prevalence of stunting is great. In the subgroup analysis, the Amhara region, followed by the Oromia region and then the Tigray region had the highest prevalence of stunting

Vancomycin-Resistant Enterococci (VRE) are on the rise worldwide. Here, we report the first prevalence of VRE in Nigeria using systematic review and meta-analysis. International databases MedLib, PubMed, International Scientific Indexing (ISI), Web of Science, Scopus, Google Scholar, and African journals online (AJOL) were searched. Information was extracted by two independent reviewers, and results were reviewed by the third. Two reviewers independently assessed the study quality using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist. OpenMeta analyst was used. The random effect was used, and publication bias was assessed using a funnel plot. Between-study heterogeneity was assessed, and the sources were analysed using the leave-one-out meta-analysis, subgroup analysis, and meta-regression. Nineteen studies met the eligibility criteria and were added to the final meta-analysis, and the study period was from 2009–2018. Of the 2552 isolates tested, 349 were VRE, and E. faecalis was reported the most. The pooled prevalence of VRE in Nigeria was estimated at 25.3% (95% CI; 19.8–30.8%; I2 = 96.26%; p < 0.001). Between-study variability was high (t2 = 0.011; heterogeneity I2 = 96.26% with heterogeneity chi-square (Q) = 480.667, degrees of freedom (df) = 18, and p = 0.001). The funnel plot showed no publication bias, and the leave-one-out forest plot did not affect the pooled prevalence. The South-East region had a moderate heterogeneity though not significant (I2 = 51.15%, p = 0.129). Meta-regression showed that all the variables listed contributed to the heterogeneity except for the animal isolate source (p = 0.188) and studies that were done in 2013 (p = 0.219). Adherence to proper and accurate antimicrobial usage, comprehensive testing, and continuous surveillance of VRE are required.
