Background: Asymptomatic SARS-CoV-2 infections are responsible for potentially significant transmission of COVID-19. Worldwide, a number of studies were conducted to estimate the magnitude of asymptomatic COVID-19 cases. However, there is a need for more robust and well-designed studies to have a relevant public health intervention. Synthesis of the available studies significantly strengthens the quality of evidences for public health practice. Thus, this systematic review and meta-analysis aimed to determine the overall magnitude of asymptomatic COVID-19 cases throughout the course of infection using available evidences.Methods: We followed the PRISMA checklist to present this study. Two experienced review authors (MA and DBK) were systematically searched international electronic databases for studies. We performed meta-analysis using R statistical software. The overall weighted proportion of asymptomatic COVID-19 cases throughout the course infection was computed. The pooled estimates with 95% confidence intervals were presented using forest plot. Egger’s tests were used to assess publication bias, and primary estimates were pooled using a random effects model. Furthermore, a sensitivity analysis was conducted to assure the robustness of the result.Results: A total of 28 studies that satisfied the eligibility criteria were included in this systematic review and meta-analysis. Consequently, in the meta-analysis, a total of 6,071 COVID-19 cases were included. The proportion of asymptomatic infections among the included studies ranged from 1.4% to 78.3%. The findings of this meta-analysis showed that the weighted pooled proportion of asymptomatic COVID-19 cases throughout the course of infection was 25% (95%CI: 16–38). The leave-one out result also revealed that the weighted pooled average of asymptomatic SARS-CoV-2 infection was between 28% and 31.4%.Conclusions: In conclusion, one-fourth of SARS-CoV-2 infections are remained asymptomatic throughout the course infection. Scale-up of testing, which targeting high risk populations is recommended to tackle the pandemic.

Globally, pneumonia is a major cause of morbidity and mortality among children which leads to over 156 million episodes and 14.9 million hospitalizations each year. Besides this fact, the recovery time and predictors of children’s hospitalization related to severe community-acquired pneumonia is not well known. Therefore, the aim of this study was to estimate the median time to recovery and its predictors among severe community-acquired pneumonia patients admitted to the pediatric ward, Debre Markos referral hospital, North West Ethiopia. An institution-based retrospective follow-up study was employed among 352 records of children who were admitted starting from January 2016 to December 2018. Patients' charts were retrieved using a structured data extraction tool. Cox proportional hazard model assumption and model fitness was checked. Stratified Cox regression was fitted as a final model. Hazard ratio with its 95% confidence interval was used and P-value < 0.05 was considered as a statistically significant association. The overall median recovery time was 4 days IQR (3–7). Recovery rate from severe community acquired pneumonia was 16.25 (95% CI: 14.54–18.15) per 100 person day observation. Age (AHR; 0.94 95% CI (0.90–0.98)), being stunted (AHR; 0.62 95% CI (0.43–0.91)), presence of danger sign at admission (AHR; 0.61 95% CI (0.40–0.94)), late presentation to seek care(AHR; 0.64 95% CI (0.47–0.88)) and co-morbidity (AHR; 0.45 95% CI (0.35–0.58)) were significant predictors of recovery time. The median recovery time from severe community-acquired pneumonia was long so that measures to reduce recovery time should be strengthened.

To estimate the pooled national burden of occupational stress, burnout, and contributing factors among health care workers in Ethiopia. Both published and unpublished observational studies conducted on the burden of occupational stress and burnout among health workers in Ethiopia were included. This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered on PROSPERO (CRD42020166585). The eligibility of the studies was evaluated based on predetermined inclusion and exclusion criteria. Data extraction was conducted using major databases; PubMed, Google Scholar, Cumulative Index to Nursing and Allied Health, Scopes, Cochrane Library, the Web of Science, and African Journals Online were involved in the review. Two reviewers extracted data independently using a standardized data extraction checklist on Microsoft Excel. Any discrepancy was resolved by including the third reviewer for a possible consensus. Fourteen studies, with a total of 4066 health care workers, were included in the meta-analysis. The pooled burdens of occupational stress and burnout were 52.9% (95% confidence interval [CI], 46.2-59.7) and 39.1% (95% CI, 23.9-52.3), respectively. Major determinants of occupational stress were being female (odds ratio [OR], 1.9; 95% CI, 1.1-3.3), being younger (OR, 1.4; 95% CI, 1.03-1.9), having a lower educational level (OR, 2.7; 95% CI, 1.05-7.2), and being satisfied with a job (OR, 0.3; 95% CI, 0.2-0.5). Being married (OR, 0.7; 95% CI, 0.5-0.9), having a lower educational level (OR, 0.5; 95% CI, 0.4-0.8), and working in shifts (OR, 0.7; 95% CI, 0.5-0.9) were significant predictors of burnout. More than half and more than one-third of health care workers were affected by occupational stress and burnout, respectively, in Ethiopia, and sociodemographic and occupation-related factors were significant factors. Measures that improve job satisfaction, career development, and educational opportunities should be strengthened.

Background: As compared to other regions of the world, Sub Saharan Africa (SSA) is the region with the highest neonatal mortality and is the region showing the least progress in the reduction of newborn death. Despite better progress made in reducing neonatal mortality, Ethiopia contributes the highest rate of neonatal death in Africa. In Ethiopia, findings from few studies were inconsistent and there is a need to systematically pool existing data to determine the impact of antenatal care on neonatal mortality among mother-neonate pairs in Ethiopia.Methods: Published articles from various electronic databases such as Medline, Hinari, Pub Med, Cochrane library, the Web of Science, and Google Scholar were accessed. Also, unpublished studies from library catalogs were identified. All observational studies that were conducted on the association between antenatal care follow-up and neonatal mortality among neonates in Ethiopia were included. Data were extracted on the Microsoft Excel spreadsheet and analyzed using STATA 14.1 version. A random-effects model was used to estimate the pooled estimate with a 95% confidence interval (CI). Forest plots were used to visualize the presence of heterogeneity and estimate the pooled impact on antenatal care on neonatal mortality. The presence of publication bias was assessed by funnel plots and Egger’s statistical tests.Results: Initially, a total of 345 studies were accessed. Finally, 28 full-text studies were reviewed and fourteen studies fulfilled inclusion criteria and included in the final meta-analysis. The overall pooled estimate indicates the odds of neonatal death among neonates from women with antenatal care were 65% lower than those neonates from women who had no antenatal care follow-up (OR: 0.35, 95% CI: 0.24, 0.51).Conclusions: In this systematic review and meta-analysis, lack of ANC follow-up increase the probability of neonatal mortality as compared to having ANC follow-up. Thus, we will recommend for more coverages of appropriate antenatal care where risk groups can best be identified and managed.

Background: Longitudinal cohort studies across the lifespan suggest an association between ultra-processed food (UPF) and depression. However, the effect of UPF on depression and mental health in older adults has not been determined. Therefore, this study investigated the effect of UPF on depressive symptoms and mental health in community-dwelling older adults. Methods: A pragmatic target trial was designed and emulated using the ASPirin in Reducing Events in the Elderly longitudinal data. Participants were community-dwelling older adults (≥ 70 years) in Australia. We specified and emulated the protocol of a two-arm randomised pragmatic clinical trial using the level of UPF consumption as the intervention. Greater than or equal to 4 servings of UPF per day was considered the intervention, with less than 4 servings per day the control. Dietary consumption was assessed using a mail-based diet screening questionnaire, and the level of food processing was classified based on the NOVA classification. The study outcomes were depressive symptoms, defined as a score of ≥ 8 on the Center for Epidemiological Studies Depression 10-item scale, and general mental health, defined by the mental component summary score of the Short Form-12. We applied inverse probability treatment weighting to balance confounders. Marginal structural models were employed to estimate the population-level average effect of intervention using generalised estimated equations. Results: A total of 11,192 participants (3415 intervention and 7777 control) were eligible for the emulation. High UPF consumption at time zero was associated with an increased risk of depressive symptoms at follow-ups (RR: 1.10; CI: 1.04–1.18). The finding was consistent with sensitivity analyses; after excluding participants on antidepressants at time zero, the risk of depressive symptoms in the intervention group was increased by 11% compared to the control (RR: 1.11; 95% CI: (1.04–1.20)). Consumption of UPF adversely affected the mental component quality of life (β: − 0.40; CI: − 0.65 to − 0.15). Conclusions: A higher level of UPF consumption was associated with a higher risk of depressive symptoms and adversely affected mental health among older adults.

Background. Continuum care is a basic package approach for women to receive essential services throughout pregnancy, childbirth, and postpartum, and it is critical for women and their infants’ survival and well-being. Although it is an effective strategy for improving maternal and child health, it has not been implemented adequately in less developed countries, primarily in sub-Saharan Africa, including Ethiopia, where 55% of women have been dropped out from the continuum of care. Therefore, this study is aimed at assessing maternity continuum care completion and its associated factors within northwest Ethiopia, 2020. Materials and Methods. A community-based cross-sectional study design was considered among 504 women from March 10 to March 30, 2020, using pretested and structured questionnaires administered via face-to-face interviews. To select study participants, a simple random sampling technique was used. Data were coded, checked, and entered into EpiData software (V. 4.2), then transferred to SPSS (V. 25) for further analysis. A bivariable analysis with 95% CI was performed, and variables with 0.25 during binary logistic regression were entered into a multivariable analysis to assess predictors’ independent effect. Results. About 177 (37.6%) women completed maternal continuum care. Women with secondary education and above ( , 95% CI 1.42-5.32), urban residence ( , 95% CI 1.35-4.45), using ambulance transport ( , 95% CI 2.19-7.19), mass media exposure ( , 95% CI 2.02-6.56), and distance from health facilities ( , 95% CI 1.84-5.63) showed significant positive associations with completion of maternity continuum care. Conclusion. However, a higher proportion of mothers completed the continuum of maternity care in the district than Ethiopian Demographic and Health Survey 2016 (9.1%); further interventions are compulsory to reach the acceptable level. Hence, comprehensive awareness-raising, education, and promotion activities at the community and health facility levels and empowering women in health care and decision-making backing to expand the completion of maternity continuum of care are necessary.
