High Incidence of Esophageal Cancer in Women in Eritrea and Its Potential Link to Low Age at Menopause: Evidence from a 10-Year Retrospective Data Analysis.

Background: Detecting a group of esophageal cancer (EC) cases in endemic regions is essential in identifying high-risk populations and executing appropriate interventions. The main aim of this study was to determine the epidemiology of EC in Eritrea. Methods: A retrospective (period: 2011 - 2021) study was carried out by abstracting data on EC patients from the logbook kept at the National Health Laboratory (ENHL). Information on socio-demographic, clinical history, and biopsy analysis findings was collected. For the statistical assessment of data, the End Results (SEER) Joinpoint Regression Program (V.4.5.0.1) was used to calculate crude incidence rate (CIR), age-adjusted incidence rate (ASR), and estimated annual percentage change (EAPC) by sex, age, and histotype. Results: A total of 189 patient's samples (134 (70.9%) females vs. 55 (29.1%) males, ratio 2.43 : 1) were evaluated. Of the 155 patients with EC, 44 (28.4%) and 111 (71.6%) were diagnosed with esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC), respectively (AC/ESCC ratio, 0.4). The median age (IQR) of patients with EC was 60 years (46.0 - 70 years) - (males 62 (IQR: 49.0 - 77 years) vs. females 60 (IQR: 46 -67 years), p-value =0.43. Within age bands, the F: M ratios in patients with ESCC were as follows: >20 -29 years =2: 1; 30-39 years =8 : 1; 40 - 49 years =10.5 : 1; 50-59 years =6.67 : 1; 60-69 years =3.25.1; 70-79 years =1.5 : 1 and>80 years =2 : 1. The all-age CIR and ASR for EC were 0.468 per 100 000 and 2.281 per 100 000 persons, respectively. Similarly, the all-age ASR for both males and females was 2.88 per 100 000 and 1.61 per 100 000. Over the study period, the EAPC for all cases was -3.0% (95% CI, -11.3 to 6.1, p-value =0.455). Conclusion: In large part, EC is a women's disease in Eritrea. The unusually high incidence of ESCC and the high female-to-male ratio point at sex-dependent exposures as a major driver of the EAC epidemic in the country. Therefore, research on the risk factors of EC in Eritrea is urgently needed.

Health care managers' perspectives on workforce licensing practice in Ethiopia: A qualitative study.

BACKGROUND: Professional licensing bodies are valuable sources for tracking the health workforce, as many skilled health-care providers require formal training, registration, and licensure. Regulatory activities in Ethiopia were not effectively implemented due to poor follow-up and gaps in skilled human resources, budget, and information technology infrastructure. OBJECTIVE: The aim of this study was to explore and describe the lived experiences and challenges faced by health care managers in health professionals' licensure practices in Ethiopia. METHODS: A cross-sectional study design with a phenomenological approach was employed between March 26 and April 30, 2021, to collect qualitative data. We conducted in-depth interviews with a total of 32 purposively selected health system managers. An interview guide was prepared in English, translated into Amharic, and then pretested. Audio recorded data was transcribed verbatim, translated, and analysed manually by themes and sub-themes. A member check was done to check the credibility of the result. RESULTS: The data revealed four major themes: awareness of licensing practices, enforcement of licensing practices, systems for assuring the quality of licensing practices, and challenges to licensing practices. Lack of awareness among managers about health workforce licensing was reported, especially at lower-level employers. Regulators were clear on the requirements to issue a licence to the health workforce if they are competent in the licensing exam, while human resource managers do not emphasise whether the employees have a licence or not during employment. As a result of this, non-licenced health workers were employed. Health care managers mentioned that they did not know any monitoring tools to solve the issue of working without a licence. Fraudulent academic credentials, shortage of resources (human resources, finance, equipment, and supplies), and weak follow-up and coordination systems were identified as main practice challenges. CONCLUSIONS: This study reported a suboptimal health professionals' licensing practice in Ethiopia, which is against the laws and proclamations of the country that state to employ all health workers only with professional licenses. Challenges for health professionals' licensing practice were identified as fraudulent academic credentials, a shortage of resources (HR, finance, equipment, and supplies), and a weak follow-up and coordination system. Further awareness of licensing practices should be created, especially for lower-level employers. Regulators shall establish a reliable digital system to consistently assure the quality of licensing practices. Health care managers must implement mechanisms to regularly monitor the licensing status of their employees and ensure that government requirements are met. Collaboration and regular communication between regulators and employers can improve quality practices.

Real-world treatment outcome of direct-acting antivirals and patient survival rates in chronic hepatitis C virus infection in Eritrea.

Reliable real-world data on direct acting anti-retroviral (DAA) uptake and treatment outcomes are lacking for patients with hepatitis C virus (HCV) in sub-Saharan Africa. This study provides data on HCV DAA-based treatment outcomes, mortality, loss-to-follow up, and associated factors among patients in Eritrea. A multicenter retrospective observational cohort study was conducted in two tertiary hospitals in Asmara, Eritrea. A structured checklist was used to collect data from patient's cards. Descriptive and inferential statistics used included means (± Standard deviation (SD), medians (Interquartile range (IQR), chi-squire (χ2), Kaplan-Meier estimates, and multivariate Cox proportional hazard models. A total of 238 patients with median age of 59 years (IQR 50-69 years) were enrolled in the study. Out of the 227 patients initiated on treatment, 125 patients had viral load measurements at 12 weeks after end of treatment (EOT) whereas 102 patients had no viral load measurements at 12 weeks EOT. Among the patients with HCV RNA data post-EOT 12, 116 (92.8%) had sustained viral response (SVR). The prevalence of death and loss-to-follow up (LTFU) were (7.5%, 95% CI 1.7-4.1) and 67 (28.1%, 95% CI 22.3-33.9) translating into an incidence of 1.1 (95% CI 0.8-1.5) per 10,000 person days. Independent predictors of LTFU included the enrollment year (2020: aHR = 2.2, 95% CI 1-4.7; p value = 0.04); Hospital (Hospital B: aHR = 2.2, 95% CI 1-4.7; p value = 0.03) and the FIB-4 score (FIB-Score < 1.45: aHR = 3.7, 95% CI 1.2-11.5; p value = 0.02). The SVR rates achieved in this cohort were high. However, high LTFU and high mortality driven largely by late presentation and suboptimal population screening/case finding, were uncovered. These challenges can be addressed by test-and-treat programs that simultaneously prioritize programmatic screening, decentralization of care, and better patient tracking in the HCV care cascade.

Epidemiology of confirmed measles virus cases, surveillance, incidence, and associated factors in Eritrea: 18-year retrospective analysis.

Background: Despite the outstanding measles vaccine coverage (MVC) in Eritrea, sporadic outbreaks are not uncommon. Therefore, understanding the incidence of laboratory-confirmed measles virus cases, related factors, and spatial inequalities in testing and surveillance remains crucial. In this analysis, we evaluated the incidence and spatiotemporal distribution of measles in Eritrea. An evaluation of the factors associated with measles vaccination and IgM positive (+) febrile rash was also undertaken. Methods: A retrospective (period: 2002-2020) study was carried out by abstracting data from the integrated disease surveillance and response database (IDSR). Data was analyzed using descriptive statistics and binary logistic regression. Spatial variability and distribution of confirmed cases was evaluated using ArcGIS Pro version 3.0.1. Results: In total, 9,111 suspected cases, 2,767 [1,431 (51.7%) females] were serologically tested. The median (IQR) age, minimum-maximum age were 7 years (IQR: 4-14 years) and 1 month-97 years, respectively. Among the 608(21.9%) laboratory-confirmed cases, 534 (87.8%) were unvaccinated and 53 (9.92%) were < 1 year old. The crude incidence rate for MV was 14/100,000 persons. The age-specific positivity rate per 100,000 suspected cases tested was 21.5 with individuals >30 years presenting with the highest rates (69.9/100,000). Higher odds (OR) of MV test positivity was associated with age at onset - higher in the following age-bands [10-14 years: OR = 1.6 (95%CI, 1.1-2.2, value of p = 0.005); 15-29 years: OR = 7.0 (95%CI, 5.3-9.2, value of p = 0.005); and > =30 years: OR = 16.7 (95%CI, 11.7-24) p < 0.001]. Other associations included: Address - higher in Anseba (OR = 2.3, 95%CI: 1.7-3.1, value of p<0.001); Debub (OR = 2.7, 95%CI: 1.9-3.9, value of p < 0.001); Gash-Barka (OR = 15.4, 95%CI: 10.9-21.7, value of p < 0.001); Northern Red Sea (OR = 11.8, 95%CI: 8.5-16.2, value of p < 0.001); and Southern Red Sea (OR = 14.4, 95%CI: 8.2-25.2, value of p < 0.001). Further, test positivity was higher in health centers (OR = 2.5, 95%CI: 1.9-3.4, value of p < 0.001) and hospitals (OR = 6.8, 95%CI: 5.1-9.1, value of p < 0.001). Additional factors included vaccination status - higher in the unvaccinated (OR = 14.7, 95%CI: 11.4-19.1, value of p < 0.001); and year of onset of rash - (higher >2015: OR = 1.4, 95%CI: 1.1-1.7, value of p<0.001). Uptake of measles vaccine associated with a similar complement of factors. Conclusion: In large part, efforts to eliminate measles in Eritrea are hindered by disparities in vaccine coverage, under-surveillance, and low vaccination rates in neighboring countries. Enhanced surveillance and regional micro planning targeting hard-to-reach areas can be an effective strategy to improve measles elimination efforts in Eritrea.

Antiretroviral therapy regimen modification rates and associated factors in a cohort of HIV/AIDS patients in Asmara, Eritrea: a 16-year retrospective analysis.

Combined antiretroviral therapy (cART) durability and time to modification are important quality indicators in HIV/AIDs treatment programs. This analysis describes the incidence, patterns, and factors associated with cART modifications in HIV patients enrolled in four treatment centers in Asmara, Eritrea from 2005 to 2021. Retrospective cohort study combining data from 5020 [males, 1943 (38.7%) vs. females, 3077 (61.3%)] patients were utilized. Data on multiple demographic and clinical variables were abstracted from patient's charts and cART program registry. Independent predictors of modification and time to specified events were evaluated using a multi-variable Cox-proportional hazards model and Kaplan-Meier analysis. The median (±IQR) age, CD4+ T-cell count, and proportion of patients with WHO Clinical stage III/IV were 48 (IQR 41-55) years; 160 (IQR 80-271) cells/µL; and 2667 (53.25%), respectively. The cumulative frequency of all cause cART modification was 3223 (64%): 2956 (58.8%) substitutions; 37 (0.7%) switches; and both, 230 (4.5%). Following 241,194 person-months (PMFU) of follow-up, incidence rate of cART substitution and switch were 12.3 (95% CI 11.9-12.8) per 1000 PMFU and 3.9 (95% CI 3.2-4.8) per 10,000 PMFU, respectively. Prominent reasons for cART substitution included toxicity/intolerance, drug-shortage, new drug availability, treatment failure, tuberculosis and pregnancy. The most common adverse event (AEs) associated with cART modification included lipodystrophy, anemia and peripheral neuropathy, among others. In the adjusted multivariate Cox regression model, Organisation (Hospital B: aHR = 1.293, 95% CI 1.162-1.439, p value < 0.001) (Hospital D: aHR = 1.799, 95% CI 1.571-2.060, p value < 0.001); Initial WHO clinical stage (Stage III: aHR = 1.116, 95% CI 1.116-1.220, p value < 0.001); NRTI backbone (D4T-based: aHR = 1.849, 95% CI 1.449-2.360, p value < 0.001) were associated with increased cumulative hazard of treatment modification. Baseline weight (aHR = 0.996, 95% CI 0.993-0.999, p value = 0.013); address within Maekel (aHR = 0.854, 95% CI 0.774-0.942, p value = 0.002); AZT-based backbones (aHR = 0.654, 95% CI 0.515-0.830, p value < 0.001); TDF-based backbones: aHR = 0.068, 95% CI 0.051-0.091, p value < 0.001), NVP-based anchors (aHR = 0.889, 95% CI 0.806-0.980, p value = 0.018) were associated with lower cumulative hazards of attrition. The minimal number of switching suggests inadequate VL testing. However, the large number of toxicity/intolerance and drug-shortage driven substitutions highlight important problems in this setting. Consequently, the need to advocate for both sustainable access to safer ARVs in SSA and improvements in local supply chains is warranted.

Prevalence and factors associated with pediatric HIV therapy failure in a tertiary hospital in Asmara, Eritrea: A 15-year retrospective cohort study.

INTRODUCTION: Treatment failure (TF) in HIV infected children is a major concern in resource-constrained settings in Sub-Saharan Africa (SSA). This study investigated the prevalence, incidence, and factors associated with first-line cART failure using the virologic (plasma viral load), immunologic and clinical criteria among HIV-infected children. METHODS: A retrospective cohort study of children (<18 years of age on treatment for a period of > 6 months) enrolled in the pediatric HIV/AIDs treatment program at Orotta National Pediatric Referral Hospital from January 2005 to December 2020 was conducted. Data were summarized using percentages, medians (± interquartile range (IQR)), or mean ± standard deviation (SD). Where appropriate, Pearson Chi-Squire (χ2) tests or Fishers exacts test, Kaplan-Meier (KM) estimates, and unadjusted and adjusted Cox-proportional hazard regression models were employed. RESULTS: Out of 724 children with at least 24 weeks' follow-up 279 experienced therapy failure (TF) making prevalence of 38.5% (95% CI 35-42.2) over a median follow-up of 72 months (IQR, 49-112 months), with a crude incidence of failure of 6.5 events per 100- person-years (95% CI 5.8-7.3). In the adjusted Cox proportional hazards model, independent factors of TF were suboptimal adherence (Adjusted Hazard Ratio (aHR) = 2.9, 95% CI 2.2-3.9, p < 0.001), cART backbone other than Zidovudine and Lamivudine (aHR = 1.6, 95% CI 1.1-2.2, p = 0.01), severe immunosuppression (aHR = 1.5, 95% CI 1-2.4, p = 0.04), wasting or weight for height z-score < -2 (aHR = 1.5, 95% CI 1.1-2.1, p = 0.02), late cART initiation calendar years (aHR = 1.15, 95% CI 1.1-1.3, p < 0.001), and older age at cART initiation (aHR = 1.01, 95% CI 1-1.02, p < 0.001). CONCLUSIONS: Seven in one hundred children on first-line cART are likely to develop TF every year. To address this problem, access to viral load tests, adherence support, integration nutritional care into the clinic, and research on factors associated with suboptimal adherence should be prioritized.

The Presence of Antineutrophil Cytoplasmic Antibodies and Antiphospholipid Antibodies in Patients with Severe Acute Respiratory Syndrome Coronavirus 2: A Case-Control Study among Sudanese Patients.

Patients infected with COVID-19 are at an increased risk for thrombosis, suggesting a possible role of COVID-19 in the induction of coagulopathy. This study aimed to investigate the presence of prothrombotic antineutrophil cytoplasmic antibodies (ANCA) and antiphospholipid antibodies (aPLs) in the course of COVID-19 infection and to correlate these markers with severity and fatality, suggesting that COVID-19-induced autoimmune thrombosis is a possible axis in the inflammatory circuit of this infection. To investigate this, we conducted a case-control study which included patients with a positive reverse transcription-polymerase chain reaction (RT-PCR) test of COVID-19 and a control group with negative COVID-19 PCR and antibody (IgG-IgM and IgA nucleoprotein) ELISA results. An indirect immunofluorescence assay using granulocyte biochips (Aesku slides from AESKU DIAGNOSTICS, Germany) was used to detect ANCA (IgG), as well as multiplex ELISA for the detection of antiphospholipid antibodies for all patients with COVID-19 and for the control group. The results revealed the detection of antiphospholipid antibodies (IgG) in one patient out of the 45 patients in the case group. 1/45(2.2%) and 7/45(15.6%) tested positive for ANCA. Five were men and two were females, with one case revealed to be positive for both aPL and ANCA. A cytoplasmic reaction on the eosinophil granulocytes was observed in 2 cases; both were positive for ANCA. Other markers (CRP, APTT, PT, INR, ESR, and neutrophil and lymphocyte counts) were included in the study, along with demographic data. No aPL or ANCA reactions were detected for any of the control groups. These findings suggest that aPL and ANCA may be induced during the course of inflammation in COVID-19 and possibly contribute to the disease's severity and mortality.

Determinants of therapy failure among adults on first-line antiretroviral therapy in Asmara, Eritrea: a multicenter retrospective matched case-control study.

BACKGROUND: Information on treatment failure (TF) in People living with HIV in a data-poor setting is necessary to counter the epidemic of TF with first-line combined antiretroviral therapies (cART) in sub-Saharan Africa (SSA). In this study, we examined the risk factors associated with TF in Asmara, Eritrea from 2001 to 2020. METHODS: A multicenter, retrospective 1:2 matched (by age and gender) case-control study was conducted in four major hospitals in Asmara, Eritrea on adults aged ≥ 18 years who were on treatment for at least 6 months. Cases were patients who fulfills at least one of the WHO therapy failure criterion during the study period. Controls were randomly selected patients on first-line treatment and plasma viral load < 1000 copies/ml in their latest follow-up measurement. Multivariable logistic regression analysis was conducted to identify risk factors for TF. All P-values were 2-sided and the level of significance was set at P < 0.05 for all analyses. RESULTS: Of the 1068 participants (356 cases; 712 controls), 585 (54.7%) were females. The median age at treatment initiation was 46 years [interquartile range (IQR): 39-51]. Median time to combined antiretroviral therapy (cART) failure was 37 months (IQR = 24-47). In the multivariate analysis, factors associated with increased likelihood of TF included initial nucleoside reverse transcriptase inhibitors (NRTI) backbone (Zidovudine + Lamivudine (AZT + 3TC): adjusted odds ratio (aOR) = 2.70, 95% Confidence interval (CI): 1.65-4.41, P-value < 0.001), (Abacavir + lamivudine (ABC + 3TC): aOR = 4.73, 95%CI: 1.18-18.92, P-value = 0.028], and (Stavudine + Lamivudine (D4T + 3TC): aOR = 5.00; 95% CI: 3.03-8.20, P-value < 0.001) in comparison to Emtricitabine and Tenofovir diproxil fumarate (FTC + TDF). Additional associations included prior exposure to cART (aOR = 2.28, 95%CI: 1.35-3.86; P- value = 0.002), record of sub-optimal drug adherence (aOR = 3.08, 95%CI: 2.22-4.28; P < 0.001), ambulatory/bedridden at presentation (aOR = 1.61, 95%CI: 1.12-4.28; P-value = 0.010), presence of comorbidities (aOR = 2.37; 95%CI: 1.36-4.10, P-value = 0.002), duration of cART (< 5 years: aOR: 5.90; 95% CI: 3.95-8.73, P-value < 0.001), and use of SMX-TMP prophylaxis (aOR = 2.00, 95%CI, 1.44-2.78, P-value < 0.001). CONCLUSION: Our findings underscore the importance of optimizing cART adherence, diversification of cART regimens, and interventions directed at enhancing early HIV diagnosis, prompt initiations of treatment, and improved patient-focused monitoring of treatment response.

Attrition and associated factors among children living with HIV at a tertiary hospital in Eritrea: a retrospective cohort analysis.

BACKGROUND: Reducing attrition in paediatric HIV-positive patients using combined antiretroviral therapy (cART) programmes in sub-Saharan Africa is a challenge. This study explored the rates and predictors of attrition in children started on cART in Asmara, Eritrea. METHODS: This was a retrospective cohort study using data from all paediatric patients on cART between 2005 and 2020, conducted at the Orotta National Referral and Teaching Hospital. Kaplan-Meier estimates of the likelihood of attrition and multivariate Cox proportional hazards models were used to assess the factors associated with attrition. All p values were two sided and p<0.05 was considered statistically significant. RESULTS: The study enrolled 710 participants with 374 boys (52.7%) and 336 girls (47.3%). After 5364 person-years' (PY) follow-up, attrition occurred in 172 (24.2%) patients: 65 (9.2%) died and 107 (15.1%) were lost to follow-up (LTFU). The crude incidence rate of attrition was 3.2 events/100 PY, mortality rate was 2.7/100 PY and LTFU was 1.2/100 PY. The independent predictors of attrition included male sex (adjusted HR (AHR)=1.6, 95% CI: 1 to 2.4), residence outside Zoba Maekel (AHR=1.5, 95% CI: 1 to 2.3), later enrolment years (2010-2015: AHR=3.2, 95% CI: 1.9 to 5.3; >2015: AHR=6.1, 95% CI: 3 to 12.2), WHO body mass index-for-age z-score <-2 (AHR=1.4, 95% CI: 0.9 to 2.1), advanced HIV disease (WHO III or IV) at enrolment (AHR=2.2, 95% CI: 1.2 to 3.9), and initiation of zidovudine+lamivudine or other cART backbones (unadjusted HR (UHR)=2, 95% CI: 1.2 to 3.2). In contrast, a reduced likelihood of attrition was observed in children with a record of cART changes (UHR=0.2, 95% CI: 0.15 to 0.4). CONCLUSION: A low incidence of attrition was observed in this study. However, the high mortality rate in the first 24 months of treatment and late presentation are concerning. Therefore, data-driven interventions for improving programme quality and outcomes should be prioritised.

Health professionals' licensing: the practice and its predictors among health professional hiring bodies in Ethiopia.

BACKGROUND: Evidence suggests that not all human resource departments have hired their facility staff based on federal licensing standards, with some hiring without an active license. This is common in some, if not all, parts of the country. The paucity of healthcare experts, high turnover rates, employee burnout, and challenges in training and development issues were all key recruiting challenges globally. OBJECTIVE: To assess the practice of health professionals' licensing and its predictors among hiring bodies in Ethiopia, March 24/2021-May 23/2021. METHODS: A cross-sectional study was conducted in privately and publicly funded health facilities throughout Ethiopia. For each region, a stratified sampling strategy was utilized, followed by a simple random sampling method. Documents from the recruiting bodies for health professionals were reviewed. A pretested structured questionnaire and document review tool were used to extract data confidentially. A descriptive analysis of the basic hiring body characteristics was conducted. Hiring body characteristics were analyzed in bivariate and multivariate logistic regression to identify factors associated with best health professionals licensing practice. Data management and analysis were conducted with Epi-Data version 4.4.3.1 and SPSS version 23, respectively. RESULTS: The analysis included 365 hiring bodies and 4991 files of health professionals (1581 from private and 3410 from public health organizations). Out of 365 hiring bodies studied, 66.3% practiced health professional licensing. A total of 1645 (33%) of the 4991 professionals whose files were reviewed were found to be working without any professional license at all. Furthermore, about 2733 (55%) have an active professional license, and about 603 (12%) were found to work with an expired license. Being a private facility (adjustedOR = 21.6; 95% CI = 8.85-52.55), obtaining supervision from a higher organ (adjustedOR = 19.7; 95%CI: 2.3-169.1), and conducting an internal audit (adjustedOR = 2.7; 95% CI: 1.15-6.34) were predictors of good licensing practice. CONCLUSIONS: The licensing of health practitioners was poorly practiced in Ethiopia as compared to the expected proclamation of the country. A system for detecting fake licenses and controlling revoked licenses does not exist in all regions of the country.

Portrait of the Emergency Department at Orotta National Referral and Teaching Hospital in Asmara, Eritrea: A Prospective Observational Study.

Background: Provision of high-quality emergency care for acute, life-threatening illnesses can significantly reduce DALY and mortality in sub-Saharan Africa. Here, we present data on the profile of an Emergency Department (ED) in the largest referral hospital in Eritrea and potential gaps for intervention. Patients and Methods: This was a prospective single-center observational study of 1093 patients who presented to the ED between September and October of 2020. Data were collected using a questionnaire from the patients' interview, observation and medical record review. The data were summarized using descriptive statistics and where applicable logistic regressions were performed. Results: The median age was 45.0 years among the patients. In terms of acuity, 741 (68.5%), 283 (26.2%), 48 (4.4%), 10 (0.9%) patients were triaged as green, yellow, red, and black, respectively. In addition, the number of self-referred patients was 857 (79.1%) and among all the visitors, 376 (34.9%) used Ambulance service. The median ± IQR for ED length of stay (LOS) was 2.7 (1.4-10.0) Hours. Further, 154 (14.4%) patients stayed in the ED for >24 hours. The hospitalization rate was 146 (14.7%). In the multivariate analysis, higher likelihood of prolonged ED LOS was observed in: medical department patients (aOR = 3.53, 95% CI = 2.03-6.14); patients referred from primary health-care centers (aOR = 2.63, 95% CI = 1.10-6.30) and hospital (aOR = 3.70, 95% CI = 2.15-6.37). Prolonged ED LOS was also associated with prior emergency visit (aOR = 1.96, 95% CI = 1.13-3.40); consultation (aOR = 12.27, 95% CI = 6.98-21.56); the need for inpatient admission (aOR = 2.34, 95% CI = 1.38-3.96); and the need for investigation and treatment (aOR = 2.03, 95% CI = 1.07-3.85). Conclusion: Improvements regarding ED specialist personnel, inpatient ward capacity, availability of investigations throughout the day and night shifts, amendments in referral system, strengthening ED and critical care capacity in zonal referral hospitals, and access to quality care among the non-communicable disease patients may ameliorate most of the bottlenecks observed in this set-up.

A community based cross sectional study on the prevalence of dyslipidemias and 10 years cardiovascular risk scores in adults in Asmara, Eritrea.

Despite the contribution of dyslipidemia to the high and rising burden of arteriosclerotic cardiovascular disease (CVD) in Sub-Saharan Africa; the condition is under-diagnosed, under-treated, and under-described. The objective of this study was to explore the prevalence of dyslipidemias, estimate a 10-year cardiovascular disease risk and associated factors in adults (≥ 35 to ≤ 85 years) living in Asmara, Eritrea. This population-based cross-sectional study was conducted among individuals without overt CVDs in Asmara, Eritrea, from October 2020 to November 2020. After stratified multistage sampling, a total of 386 (144 (37%) males and 242 (63%) females, mean age ± SD, 52.17 ± 13.29 years) respondents were randomly selected. The WHO NCD STEPS instrument version 3.1 questionnaire was used to collect data. Information on socio-demographic variables was collected via interviews by trained data collectors. Measurements/or analyses including anthropometric, lipid panel, fasting plasma glucose, and blood pressure were also undertaken. Finally, data was analyzed by using Statistical Package for Social Sciences version 26.0 for Windows (SPSS Inc., Chicago, IL, USA). All p-values were 2-sided and the level of significance was set at p < 0.05 for all analyses. The frequency of dyslipidemia in this population was disproportionately high (87.4%) with the worst affected subgroup in the 51-60 age band. Further, 98% of the study participants were not aware of their diagnosis. In terms of individual lipid markers, the proportions were as follows: low HDL-C (55.2%); high TC (49.7%); high LDL (44.8%); high TG (38.1%). The mean ± SD, for HDL-C, TC, LDL-C, non-HDL-C, and TG were 45.28 ± 9.60; 205.24 ± 45.77; 130.77 ± 36.15; 160.22 ± 42.09 and 144.5 ± 61.26 mg/dL, respectively. Regarding NCEP ATP III risk criteria, 17.6%, 19.4%, 16.3%, 19.7%, and 54.7% were in high or very high-risk categories for TC, Non-HDL-C, TG, LDL-C, and HDL-C, respectively. Among all respondents, 59.6% had mixed dyslipidemias with TC + TG + LDL-C dominating. In addition, 27.3%, 28.04%, 23.0%, and 8.6% had abnormalities in 1, 2, 3 and 4 lipid abnormalities, respectively. Multivariate logistic regression modeling suggested that dyslipidemia was lower in subjects who were employed (aOR 0.48, 95% CI 0.24-0.97, p = 0.015); self-employed (aOR 0.41, 95% CI 0.17-1.00, p = 0.018); and married (aOR 2.35, 95% CI 1.19-4.66, p = 0.009). A higher likelihood of dyslipidemia was also associated with increasing DBP (aOR 1.04 mmHg (1.00-1.09, p = 0.001) and increasing FPG (aOR 1.02 per 1 mg/dL, 95% CI 1.00-1.05, p = 0.001). Separately, Framingham CVD Risk score estimates suggested that 12.7% and 2.8% were at 10 years CVD high risk or very high-risk strata. High frequency of poor lipid health may be a prominent contributor to the high burden of atherosclerotic CVDs-related mortality and morbidity in Asmara, Eritrea. Consequently, efforts directed at early detection, and evidence-based interventions are warranted. The low awareness rate also points at education within the population as a possible intervention pathway.

Genome-wide association analysis of adaptation to oxygen stress in Nile tilapia (Oreochromis niloticus).

BACKGROUND: Tilapia is one of the most abundant species in aquaculture. Hypoxia is known to depress growth rate, but the genetic mechanism by which this occurs is unknown. In this study, two groups consisting of 3140 fish that were raised in either aerated (normoxia) or non-aerated pond (nocturnal hypoxia). During grow out, fish were sampled five times to determine individual body weight (BW) gains. We applied a genome-wide association study to identify SNPs and genes associated with the hypoxic and normoxic environments in the 16th generation of a Genetically Improved Farmed Tilapia population. RESULTS: In the hypoxic environment, 36 SNPs associated with at least one of the five body weight measurements (BW1 till BW5), of which six, located between 19.48 Mb and 21.04 Mb on Linkage group (LG) 8, were significant for body weight in the early growth stage (BW1 to BW2). Further significant associations were found for BW in the later growth stage (BW3 to BW5), located on LG1 and LG8. Analysis of genes within the candidate genomic region suggested that MAPK and VEGF signalling were significantly involved in the later growth stage under the hypoxic environment. Well-known hypoxia-regulated genes such as igf1rb, rora, efna3 and aurk were also associated with growth in the later stage in the hypoxic environment. Conversely, 13 linkage groups containing 29 unique significant and suggestive SNPs were found across the whole growth period under the normoxic environment. A meta-analysis showed that 33 SNPs were significantly associated with BW across the two environments, indicating a shared effect independent of hypoxic or normoxic environment. Functional pathways were involved in nervous system development and organ growth in the early stage, and oocyte maturation in the later stage. CONCLUSIONS: There are clear genotype-growth associations in both normoxic and hypoxic environments, although genome architecture involved changed over the growing period, indicating a transition in metabolism along the way. The involvement of pathways important in hypoxia especially at the later growth stage indicates a genotype-by-environment interaction, in which MAPK and VEGF signalling are important components.

Heritable variation in swimming performance in Nile tilapia (Oreochromis niloticus) and negative genetic correlations with growth and harvest weight.

Nile tilapia is predominantly produced in smallholder ponds without aeration. We hypothesize that Nile tilapia with high oxygen uptake efficiency (O2UE) may perform better under these conditions than Nile tilapia with low O2UE. Critical swimming speed (Ucrit, in cm s-1) is a potential indicator for O2UE. Our objectives were to estimate variance components for Ucrit and fish size at swim testing early in life, and genetic correlations (rg) between Ucrit with harvest weight (HW) and daily growth coefficient (DGC) later after grow-out in a non-aerated pond. Substantial heritability was found for absolute Ucrit (0.48). The estimated rg between absolute Ucrit and fish size at testing were all strong and positive (range 0.72-0.83). The estimated rg between absolute Ucrit and HW, and absolute Ucrit and DGC were - 0.21 and - 0.63 respectively, indicating that fish with higher absolute Ucrit had lower growth in the non-aerated pond as compared to fish with lower absolute Ucrit. These results suggest a juvenile trade-off between swimming and growth performance where fish with high Ucrit early in life show slower growth later under conditions of limited oxygen availability. We conclude that Ucrit in Nile tilapia is heritable and can be used to predict growth performance.

Exploring health workforce regulation practices and gaps in Ethiopia: a national cross-sectional study.

BACKGROUND: Health workforce regulation plays key roles in ensuring the availability of competent health workers and improving performance of the health system. In 2010, Ethiopia established a national authority aiming to ensure competence and ethics of health professionals. Subsequently, subnational regulators were established and regulatory frameworks were developed. Although there were anecdotal reports of implementation gaps, there was lack of empirical evidence to corroborate the reports. We conducted a national study to explore health professional regulation practices and gaps focusing on registration, licensing, ethics, scope of practice, and continuing professional development. METHODS: We conducted a mixed methods cross-sectional survey using structured interview with a national representative sample of health professionals and key informant interviews with health regulators and managers. We used two stage stratified cluster sampling to select health professionals. The quantitative data were subjected to descriptive and multivariable logistic regression analysis. We conducted thematic analysis of the qualitative data. RESULTS: We interviewed 554 health professionals in the quantitative survey. And 31 key informants participated in the qualitative part. Nearly one third of the respondents (32.5%) were not registered. Many of them (72.8%) did not renew their licenses. About one fifth of them (19.7%) did nothing against ethical breaches encountered during their clinical practices. Significant of them ever practiced beyond their scope limits (22.0%); and didn't engage in CPD in the past 1 year (40.8%). Majority of them (97.8%) never identified their own CPD needs. Health regulators and managers stressed that regulatory bodies had shortage of skilled staff, budget and infrastructure to enforce regulation. Regulatory frameworks were not fully implemented. CONCLUSIONS: Health professionals were not regulated well due to limited capacity of regulators. This might have affected quality of patient care. To ensure effective implementation of health professional regulation, legislations should be translated into actions. Draft guidelines, directives and tools should be finalized and endorsed. Capacity of the regulators and health facilities needs to be built. Reinstituting health professionals' council and regulation enforcement strategies require attention. Future studies are recommended for assessing effects and costs of weak regulation.

Practice analysis of junior doctors in Ethiopia: implications for strengthening medical education, practice and regulation.

BACKGROUND: A high performing physician workforce is critical to attain nationally set health sector goals. Ethiopia has expanded training of medical doctors. However, little is known about junior doctors' performance. Understanding medical practice is essential to inform medical education and practice, establish licensure examination and guide workforce management decisions. We conducted a practice analysis study to identify gaps in Ethiopian medical education and practice, and to determine composition of subjects in national licensing examination. METHODS: We conducted a cross-sectional study with national representative sample of junior doctors. After calculating a sample size of 198, we used a two-stage stratified cluster sampling method to select study participants. We collected data using a structured questionnaire comprising 222 tasks. Study participants reported in interviews on frequency of, competence at, and importance of doing each task for improved health outcome. We developed proportions, averages, graphs and tables. Using the results of practice analysis and experts' ratings, relative weights of subjects in the national licensing examination for medical undergraduates were determined. RESULTS: A total of 191 junior doctors participated. Most were males (74.6%) and had less than 2 years of experience (69.8%). Junior doctors frequently performed tasks of internal medicine and pediatrics. Their participation in obstetrics and gynecology, ophthalmology, psychiatry and dentistry services was infrequent. Junior doctors had competency gaps to conduct clinical procedures, research and health programming tasks. Practice analysis results and expert ratings generated comparable recommendations for composition of a national licensing examination, with more than three-quarters of the items focusing on internal medicine, pediatrics, surgery, obstetrics and gynecology, and public health. CONCLUSION: Junior doctors in Ethiopia rarely managed psychiatry, ophthalmology and dental patients. They had competence gaps in clinical procedures, research and health programming skills. The findings have implications for establishing licensing examination, and reviewing curriculum, continuing professional development, placement and rotation policy, and distribution of responsibilities.

Preparing the health workforce in Ethiopia: A Cross-sectional study of competence of anesthesia graduating students.

BACKGROUND: Efforts to address shortages of health workers in low-resource settings have focused on rapidly increasing the number of higher education programs for health workers. This study examines selected competencies achieved by graduating Bachelor of Science and nurse anesthetist students in Ethiopia, a country facing a critical shortage of anesthesia professionals. METHODS: The study, conducted in June and July 2013, assessed skills and knowledge of 122 students graduating from anesthetist training programs at six public universities and colleges in Ethiopia; these students comprise 80% of graduates from these institutions in the 2013 academic year. Data was collected from direct observations of student performance, using an objective structured clinical examination approach, and from structured interviews regarding the adequacy of the learning environment. RESULTS: Student performance varied, with mean percentage scores highest for spinal anesthesia (80%), neonatal resuscitation (74%), endotracheal intubation (73%), and laryngeal mask airway insertion check (71%). Average scores were lowest for routine anesthesia machine check (37%) and preoperative screening assessment (48%). Male graduates outscored female graduates (63.2% versus 56.9%, P = 0.014), and university graduates outscored regional health science college graduates (64.5% versus 55.5%, P = 0.023). Multivariate linear regression found that competence was associated with being male and attending a university training program. Less than 10% of the students believed that skills labs had adequate staff and resources, and only 57.4% had performed at least 200 endotracheal intubations at clinical practicum sites, as required by national standards. DISCUSSION: Ethiopia has successfully expanded higher education for anesthetists, but a focus on quality of training and assessment of learners is required to ensure that graduates have mastered basic skills and are able to offer safe services.
