RESUMEN
Background: The Tigray region of Ethiopia, which has been affected by civil war from 2020 to 2022, is facing an increase in tuberculosis in the damaged health system. Our study employed mathematical modeling to predict the incidence of tuberculosis and its trends during the war and in the post-conflict setting of Tigray, Northern Ethiopia. Methods: We predicted the incidence of tuberculosis from 2020 to 2025 in Tigray using the SEIRD model in the context of the recent war and compared it with its counterfactual trend in the absence of war. The counterfactual trend was forecasted using an autoregressive integrated moving average (ARIMA) model for stationary time-series data. We performed rolling origin cross-validation for ARIMA and sensitivity analysis for the SEIRD model. The initial tuberculosis data and model parameters were obtained from the Institute for Health Metrics and Evaluation and the literature, respectively. Results: Between 2000 and 2017, the incidence of tuberculosis in Tigray decreased at an annual rate of 3.0%. Shortly before the war, the incidence of tuberculosis in the region was 178 per 100,000 people. In a counterfactual scenario where there was no war, the incidence was projected to decrease to 144.3 in 2022 and 126.3 in 2025. However, owing to the war and siege, the SEIRD-projected incidence of tuberculosis would have increased to 965.5 (95% CI: 958.5-972.7) in 2022 and 372.4 (95% CI: 367.7-376.6) in 2025. Over 800 cases of tuberculosis per 100,000 people were attributed to the war in 2022. In the postwar period, the incidence is projected to decrease by 30% by 2023. Conclusion: The Tigray War reversed a two-decade decline in tuberculosis cases, causing a five-fold increase compared to the no-war scenario. Urgent interventions are needed to support tuberculosis prevention, testing, and treatment, particularly in key and vulnerable populations.
RESUMEN
Background: Although tuberculosis is highly prevalent in low- and middle-income countries, millions of cases remain undetected using current diagnostic methods. To address this problem, researchers have proposed prediction rules. Objective: We analyzed existing prediction rules for the diagnosis of pulmonary tuberculosis and identified factors with a moderate to high strength of association with the disease. Methods: We conducted a comprehensive search of relevant databases (MEDLINE/PubMed, Cochrane Library, Science Direct, Global Health for Reports, and Google Scholar) up to 14 November 2022. Studies that developed diagnostic algorithms for pulmonary tuberculosis in adults from low and middle-income countries were included. Two reviewers performed study screening, data extraction, and quality assessment. The study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2. We performed a narrative synthesis. Results: Of the 26 articles selected, only half included human immune deficiency virus-positive patients. In symptomatic human immune deficiency virus patients, radiographic findings and body mass index were strong predictors of pulmonary tuberculosis, with an odds ratio of >4. However, in human immune deficiency virus-negative individuals, the biomarkers showed a moderate association with the disease. In symptomatic human immune deficiency virus patients, a C-reactive protein level ⩾10 mg/L had a sensitivity and specificity of 93% and 40%, respectively, whereas a trial of antibiotics had a specificity of 86% and a sensitivity of 43%. In smear-negative patients, anti-tuberculosis treatment showed a sensitivity of 52% and a specificity of 63%. Conclusions: The performance of predictors and diagnostic algorithms differs among patient subgroups, such as in human immune deficiency virus-positive patients, radiographic findings, and body mass index were strong predictors of pulmonary tuberculosis. However, in human immune deficiency virus-negative individuals, the biomarkers showed a moderate association with the disease. A few models have reached the World Health Organization's recommendation. Therefore, more work should be done to strengthen the predictive models for tuberculosis screening in the future, and they should be developed rigorously, considering the heterogeneity of the population in clinical work.
RESUMEN
BACKGROUND: More than 70% of the health facilities in Tigray, northern Ethiopia, have been totally or partially destroyed by the recent war in the region. Diagnosis and management of tuberculosis were among many health services that suffered. In this study we assess the status of tuberculosis care in health facilities of Tigray during the recent war and compare it with the immediate pre-war state. METHODS: Using sequential mixed method, we analyzed and compared the availability of diagnostic services in 69 health facilities and the utilization of tuberculosis care in 50 of them immediately before the war (September-October 2020) and during the war (November-July 2021). TB focal persons in each selected health facility were interviewed to evaluate the status of diagnostic services. Patient service utilization was assessed using health facility registrations. We also compared the average monthly case detection rate of multidrug resistant tuberculosis in the region before and during the war. We computed summary statistics and performed comparisons using t-tests. Finally, existing challenges related to tuberculosis care in the region were explored via in-depth interviews. Two investigators openly coded and analyzed the qualitative data independently via thematic analysis. RESULTS: Among the 69 health facilities randomly selected, the registers of 19 facilities were destroyed by the war; data from the remaining 50 facilities were included in the TB service utilization analysis. In the first month of the war (November 2021) the number of tuberculosis patients visiting health facilities fell 34%. Subsequently the visitation rate improved steadily, but not to pre-war rates. This reduction was significant in northwest, central and eastern zones. Tuberculosis care in rural areas was hit hardest. Prior to the war 60% of tuberculosis patients were served in rural clinics; this number dropped to an average of 17% during the war. Health facilities were systematically looted. Of the 69 institutions assessed, over 69% of the microscopes in health centers, 87.5% of the microscopes in primary hospitals, and 68% of the microscopes in general hospitals were stolen or damaged. Two GeneXpert nucleic acid amplification machines were also taken from general hospitals. Regarding drug resistant TB, the average number of multidrug resistant tuberculosis (MDR TB) cases detected per month was reduced by 41% during the war with p-value < 0.001. In-depth interviews with eight health care workers indicated that the main factors affecting tuberculosis care in the area were lack of security, health facility destruction, theft of essential equipment, and drug supply disruption. CONCLUSION AND RECOMMENDATION: Many tuberculosis patients failed to visit health facilities during the war. There was substantial physical damage to health care facilities and systematic looting of diagnostic equipment. Restoring basic public services and revitalizing clinical care for tuberculosis need urgent consideration.
RESUMEN
Introduction. Studies in Ethiopia have indicated that tuberculosis (TB) patient's elapsed a long time before initiating treatment.Gap Statement. However, there is very limited evidence on the association of treatment initiation delay with drug resistance.Research Aim. To investigate the association of delayed treatment initiation with drug resistance among newly diagnosed TB patients in Tigray, Ethiopia.Methods. We conducted a follow-up study from October 2018 to June 2020 by recruiting 875 pulmonary tuberculosis (PTB) patients from 21 randomly selected health facilities. Delays to initiate treatment and drug resistance were collected using a standardized questionnaire and standard laboratory investigation. The association of delay to initiate treatment with acquired drug resistance was modelled using penalized maximum-likelihood (PML) regression models. Data were analysed using stata software version 15. Statistical significance was reported whenever the P-value was less than 0.05.Result. The median total delay to treatment initiation was 62 days with an inter-quartile range of 16-221 days. A unit change in time to initiate treatment reduced the risk of acquired drug resistance by 3â%. Being smear-positive at the end of treatment and after 2 months of treatment initiation were significantly associated with a higher risk of acquired drug resistance. Whereas, having a mild clinical condition was associated with a lower risk of drug resistance.Conclusion. Time to treatment initiation delay is associated with an increased risk of the emergence of drug resistance. Efforts targeted towards reducing the negative effects of PTB should focus on reducing the length of delay to initiate treatment.

Background: Seizure is the most frequently observed symptom of neurological disorders and an important determinant of outcome during neonatal period. In clinical practice, it is prevalent and observed in neonates admitted to hospital in low-resources countries, but due to the paucity of studies in these regions, little is known about its pattern, clinical outcomes of hospitalization, and its predictors. Therefore, aims to evaluate seizure patterns, clinical outcomes, and its predictors among neonates admitted to the NICU of ACSH, Mekelle, and Tigray. Methods: A hospital-based cross-sectional study design was conducted among neonates with neonatal seizures admitted to NICU of Ayder Comprehensive Specialized Hospital. Data collection was done from record reviews. SPSS Version 25 was used. Descriptive statistics and bivariate logistic regressions where a p-value of <0.05 is considered statistically significant. Results: Out of 1622 NICU admissions, 155 (9.6%) were cases of neonatal seizure. The most frequently observed types of seizure in this study were subtle 70 (45.1%) and tonic 49 (31.6%) respectively. At the end of hospitalization 70.3% of neonates were discharged improved, 21.3% of neonates died and 8.4% of neonates had severe neurologic deficits. Poorly controlled seizures (AOR 4.8, 95% CI 2.6-9.2), prolonged duration of labor (AOR 4.3, 95% CI 2.2-8.8) and seizure onset <72 hours (AOR 3.7, 95% CI 1.6-8.5), respectively, were found to be independent predictors of poor neonatal outcome. Conclusion: Of all neonatal admissions, neonatal seizure was observed in close to 9.6%. The most frequently observed type of seizure was subtle. Of those admitted neonates, 30% had poor outcomes following the end of their hospitalization or when they leave against medical advice for lack of improvement). Poorly controlled seizures, prolonged duration of labor, and seizure onset <72 hours were independent predictors of poor neonatal outcomes.
RESUMEN
OBJECTIVES: The aim of this study is to determine the 12 months' discontinuation rate and associated factors among family planning clients using pills and injection. METHODS: A follow-up study was initiated to collect data from 845 family planning users between November 2017 and December 2018. An interviewer administered questionnaire was used to collect data from participants. Data were entered into EpiData version 3.1 and analyzed using SPSS version 20, where both are open-source systems. A Cox proportional-hazards model was used to estimate the hazard ratios (HR) for the rate of discontinuation among participants. RESULT: At 12 months, 63.5% of women discontinued the use of their baseline method. For the individual methods, 84% of women that chose the pill discontinued its use and for those using the injectable, 60.7% of women discontinued its use. Using the adjusted Cox proportional-hazards model, pills users (HR = 1.77; 95%CI = [1.4-2.3]), users receiving family planning services in the same room as other maternal health clinic services (HR 1.58; 95%CI = [1.16-2.2]), users served by health officers (HR = 3.7; 95%CI = [1.66-8.2]), and users not intending to use the baseline method continuously (HR = 1.6; 95%CI = [1.16-2.24]) were significantly more likely to discontinue using the baseline method. The main reason cited for discontinuation was side effects of contraception. CONCLUSIONS: The discontinuation rate of the baseline contraceptive method after 12 months was very high. To increase the continuity of contraceptive use, family planning services should be given in a separate room with effective counseling on potential side effects, provided by midwives or nurses who have good counseling skills.

BACKGROUND: Animal source foods (ASFs) are rich in high-quality proteins, including essential amino acids and highly bioavailable micronutrients vital for child growth and cognitive development. But, the daily consumption of ASFs among 6-23 months old children is very low in Tigray, Northern Ethiopia. OBJECTIVE: The study aimed to assess the effectiveness of nutrition education intervention to improve the consumption of ASFs among 6-23 months old children from rural communities with strict religious fasting traditions of avoiding intake of ASFs in Northern Ethiopia. METHODS: A quasi-experimental study was conducted in two food insecure districts namely Samre Seharti (intervention) and Tanqua Abergele (comparison). The mother-child pairs in the intervention group (n = 140) received nutrition education based on the barriers and available resources for optimal consumption of ASFs among children and followed up for nine months. The mother-child pairs in the comparison group (n = 153) received routine nutrition education. The data were collected using a pre-tested structured questionnaire. The baseline and endline data assessment included interviews on socio-demographic and socio-economic status, dietary intake, and child feeding practices. The effectiveness of the intervention was measured using the difference-in-difference (DID) analysis model. RESULTS: At endline, the consumption of ASFs among children was 19.5 percentage points higher in the intervention group compared with the comparison group (p = 0.008). In addition, there was a significant increase in egg consumption among children in the intervention group (DID of 16.9, p = 0.012) from the comparison group. No child was consuming meat at baseline in both the intervention and comparison arms and it was very low at endline (5.2% vs. 7.9%). Overall, the proportion of children that consumed eggs in the intervention group was higher than in the comparison group in households that owned sheep and goats (4.8% vs. 21.4%, p = 0.050) and chicken (6.3% vs. 43.8%, p = 0.002) after education interventions. However, no statistically significant difference was observed between cow ownership and milk consumption among children (p>0.05). CONCLUSIONS: Age-appropriate educational interventions for mothers and owning small livestock in the household can improve the consumption of ASFs and eventually the minimum diet diversity of children in communities with strict religious traditions of avoiding ASFs during the fasting seasons.

BACKGROUND: Limited studies in Ethiopia showed that infants and young children are at high risk of inadequate intake of energy and nutrients. However, inclusive assessment of both nutrient intakes and their food sources are lacking. We aimed at assessing energy and nutrient intakes and their food sources during religious fasting and non-fasting periods among 6-23 months old children in Northern Ethiopia. METHODS: Data for this longitudinal study were collected following repeated multiple-pass 24-h dietary recall technique through face-to-face interviews with primary caregivers. Using a two-stage systematic random sampling method, a total of 570 and 551 children participated respectively in the lent fasting and non-fasting periods. Energy and nutrient intakes were estimated and compared with WHO daily requirements. All foods that a child consumed on the day preceding the date of data collection were recorded and processed with database software. Chi-square and t- tests were used to analyze the data. Non-normally distributed data were analyzed using Wilcoxon signed-rank test and statistical significance was set at p < 0.05. RESULTS: The overall prevalence of child stunting was 41.4%. Almost all of children (99.6%) consumed grains, roots, and tubers. The inadequacy prevalence of energy, protein and eight selected micronutrients (calcium, iron, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin C) intake were 96.2, 44.9, and 95.5%, respectively. Calcium and zinc were the highest (100%) deficits observed across all age groups. Although consumption of animal source foods (ASFs) was very low (dairy 10.1%, meat 2.3% and eggs 23.6%), there was significantly higher consumption of meat and eggs during the non-fasting compared to fasting period (p < 0.001). CONCLUSIONS: Inadequate intake of energy and nutrients was common among 6-23 months old children. Cereals were found to be the main sources of many of the nutrients. The consumption of ASFs among 6-23-month-old children was low which was also affected by the religious fasting period. Hence, strengthening social and behavior change communication, supporting rural households to raise poultry and small ruminants is recommended.

BACKGROUND: Malaria is a major health problem in Ethiopia. Sleeping under long-lasting insecticidal nets (LLINs) is its major control strategy. Despite high LLINs use (84%) in Ziway-Dugda District, malaria remained a public health problem, raising concern on its effectiveness. Understanding the effectiveness of malaria control interventions is vital. This study evaluated the effectiveness of LLINs and determinants of malaria in Ziway-Dugda District, Arsi Zone Ethiopia. METHODS: A matched case-control study was conducted among 284 study participants (71 cases and 213 controls) in Ziway-Dugda District, Arsi Zone, Ethiopia from March to May, 2017. Three health centers were selected randomly, and enrolled individuals newly diagnosed for malaria proportionally. Cases and controls were individuals testing positive and negative for malaria using rapid diagnostic tests. Each case was matched to three controls using the age of (5 years), gender and village of residence. The information was collected using pre-tested structured questionnaires through face to face interviews and observation. Data were entered into Epi-Info version 3.5, and analysed using Stata version-12. Conditional logistic regression was performed, and odds of LLINs use were compared using matched Adjusted Odds Ratio (AOR), 95% confidence interval (CI) and p-value of < 0.05. RESULTS: One hundred twenty-three (61.2%) of the controls and 22 (32.8%) of cases had regularly slept under LLINs in the past two weeks. Using multivariate analysis, sleeping under LLINs for the past two weeks (AOR = 0.23, 95%CI = 0.11-0.45); living in houses sprayed with indoor residual spray (IRS) (AOR = 0.23, 95%CI: 0.10-0.52); and staying late outdoors at night in the past two-weeks (AOR = 2.99, 95%CI = 1.44-6.19) were determinant factors. CONCLUSIONS: Sleeping under LLINs is effective for malaria prevention in the district. IRS and staying late outdoors at night were determinants of malaria. It is recommended to increase attention on strengthening LLINs use and IRS in the area.

BACKGROUND: Thyrotoxicosis is the state of thyroid hormone excess. But, in sub-Saharan Africa (SSA), specifically Northern Ethiopia, scientific evidence about thyrotoxicosis and its cardiac complications like dilated cardiomyopathy is limited. Therefore, this study aimed to explore the thyrotoxicosis presentation and management and identify factors associated with dilated cardiomyopathy in a tertiary hospital in Northern Ethiopia. METHODS: An institution-based cross-sectional study was conducted in Ayder Comprehensive Specialized Hospital from 2017 to 2018. Data from 200 thyrotoxicosis cases were collected using a structured questionnaire. After describing variables, logistic regression was conducted to identify independent predictors of dilated cardiomyopathy. Statistical significance was declared at p < 0.05. RESULTS: Mean age at presentation of thyrotoxicosis was 45 years and females accounted for 89 % of the cases. The most frequent etiology was multinodular toxic goiter (51.5 %). As well, the most common symptoms and signs were palpitation and goiter respectively. Thyroid storm occurred in 6 % of the cases. Out of 89 patients subjected to echocardiography, 35 (39.3 %) of them had dilated cardiomyopathy. And, the odds of dilated cardiomyopathy were higher in patients who had atrial fibrillation (AOR = 15.95, 95 % CI:5.89-38.16, p = 0.001) and tachycardia (AOR = 2.73, 95 % CI:1.04-7.15, p = 0.040). All patients took propylthiouracil and 13.0 % of them experienced its side effects. Concerning ß-blockers, propranolol was the most commonly (78.5 % of the cases) used drug followed by atenolol (15.0 %). Six patients underwent surgery. CONCLUSIONS: In developing countries like Ethiopia, patients with thyrotoxicosis have no access to methimazole which is the first-line anti-thyroid drug. Besides, they greatly suffer from dilated cardiomyopathy (due to late presentation) and side effects of propylthiouracil. Therefore, we recommend that patients should get adequate health information about thyrotoxicosis and anti-thyroid drugs including their side effects. Additionally, hospitals and other concerned bodies should also avail of TSH tests and methimazole at an affordable cost. Furthermore, community awareness about iodized salt and iodine-rich foods should be enhanced.

BACKGROUND: Globally, hypertension is the most important public health issue and is a increasing health problem in Ethiopia. Blood pressure (BP) control is an ultimate therapeutic goal of hypertensive patients in reducing early complications of hypertension. Hence, this study was sought to examine the magnitude of uncontrolled BP, left ventricular hypertrophy (LVH), and treatment practice. Predictors of uncontrolled BP and LVH were also investigated. METHODS: A hospital-based cross-sectional study was conducted among 223 outpatients with hypertension on follow-up at Ayder Comprehensive Specialized Hospital (ACSH). Hypertensive patients with ≥18 years old who had been on follow-up care for at least 3 months were included in the study. Severely ill patients requiring urgent medical care and wheelchair-bound individuals or persons who had difficulty standing steady and pregnant women were excluded. Data were collected using a structured questionnaire and patients' chart review. Data were entered and analyzed using SPSS version 22.0. To identify predictors, binary logistic regression model analysis was performed. Statistical significance was set at P-value of < 0.05. RESULTS: The magnitude of uncontrolled BP (>140/90mmgH) and LVH was found to be 31.4% and 39.5%, respectively. More than half (53%) of participants were on at least two antihypertensive drug combinations of different classes. Uncontrolled BP was significantly associated with poor adherence to salt reduction in meal (Adjusted Odds Ratio (AOR) =8.552, 95% CI: 2.853, 15.638, P<0.001), non-adherence to medications (AOR =2.886, 95% CI: 1.710, 3.935, P<0.001), and taking triple-drug therapy (AOR=7.228, 95% CI: 1.110, 10.57, P=0.039). Presence of LVH was significantly associated with abdominal obesity (AOR= 2.2, 95% CI: 1.399, 4.69, P=0.003), age of ≥60 years (AOR= 2.421, 95% CI: 1.263, 4.639, P=0.008), and uncontrolled BP (AOR= 3.16, 95% CI: 1.208, 5.232, P=0.021). CONCLUSION: In this study, a significant proportion of patients with uncontrolled BP and LVH were found. Abdominal obesity, older age and uncontrolled blood pressure were predictors of LVH. Therefore, tailored interventions targeting BP control to reduce the magnitude of LVH and other early complications of hypertension deemed to be compulsory.
RESUMEN
BACKGROUND: Delayed treatment initiation of Tuberculosis patients results in increased infectivity, poor treatment outcome, and increased mortality. However, there is a paucity of evidence on the delay in new adult pulmonary Tuberculosis patients to initiate treatment in Tigray, Northern Ethiopia. OBJECTIVE: To assess the factors associated with treatment initiation delay among new adult pulmonary tuberculosis patients in Tigray, Northern Ethiopia. METHODS: The study design was cross-sectional. A total of 875 new adult pulmonary tuberculosis patients were recruited from 21 health facilities from October 2018 to October 2019. Health facilities were selected by simple random sampling technique and tuberculosis cases from the health facilities were consecutively enrolled. Data were collected using structured questionnaire within the first 2 weeks of treatment initiation. Delay was categorized as patient, health system and total delays. Data were analyzed using SPSS version 21 and logistic regression was used to identify factors associated with the odds of delays to initiate treatment. A p-value of less than 0.05 was reported as statistically significant. RESULTS: The median patient, health system and total delays were 30, 18 and 62 days, respectively. Rural residence, being poor, visiting non-formal medication sources, being primary health care and the private clinic had higher odds of patient delay whereas being HIV positive had lower odds of patient delay. Illiteracy, first visit to primary health care and private clinic had higher odds of health system delay whereas a visit to health facility one time and have no patient delay had lower odds of health system delay. CONCLUSION: The median patient delay was higher than the median health system delay before initiating treatment. Hence, improved awareness of the community and involving the informal medication sources in the tuberculosis pathways would reduce patient delay. Similarly, improved cough screening and diagnostic efficiency of the lower health facilities would shorten health system delay.

BACKGROUND: Delayed treatment initiation of tuberculosis (TB) increases disease progression and development of complications which may lead to a higher level of infectiousness, clinical severity and increased mortality. But published evidences that investigated the effect of delayed initiation of treatment on clinical severity and level of infectiousness of pulmonary tuberculosis patients is scarce in Tigray, Northern Ethiopia. OBJECTIVE: To investigate the association of delayed treatment initiation of new adult Pulmonary Tuberculosis patients with clinical severity and level of infectiousness. METHODS: In this cross-sectional study design, a total of 875 newly diagnosed adult pulmonary tuberculosis patients were recruited from 21 health facilities from October 2018 to October 2019. Health facilities and study participants were selected by a simple random sampling method. Data were collected using questionnaires through face-to-face interviews of patients within the first 2 weeks of treatment initiation. Clinical severity was assessed by Bandim tuberculosis score and level of infectiousness was assessed by smear positivity or lung cavitations. Data were analyzed using SPSS version 21 software program. Logistic regression analysis was used to ascertain the association of delay with clinical severity and level of infectiousness. P-BMC Public Health of less than 0.05 was reported as being statistically significant. RESULTS: Those who had initiated treatment without delay and those who have initiated treatment after a medium delay of 31 to 60 days were significantly associated with decreased clinical score compared to those who initiated treatment after a delay of more than two months. Compared with patients who have initiated treatment within one month, the level of infectiousness was greater for delay of 30-60 days and above 60 days. Patients having more than 3 family members have higher level of infectiousness as compared to those who have a maximum of 3 family members. Whereas, patients having at least two rooms and being HIV negative had lower levels of infectiousness compared to their counter patients. CONCLUSION: Narrowing the gap between their initial occurrence of TB symptoms and treatment initiation is the way forward to improve clinical courses of TB patients and to reduce the level of infectiousness of TB to other people from these patients.

BACKGROUND: Milk being a suitable medium for bacterial growth, it can serve as a source of bacterial contamination. Pathogenic bacteria in milk pose a serious health threat to humans and constitute about 90% of all dairy-related diseases. However, there are few studies that examined the health hazards of raw milk consumption in Ethiopia. Therefore, the objective of this study was to assess the prevalence of bacterial contamination and associated factors in milk produced for commercial purpose in Tigray region, northern Ethiopia. METHODS: This study used a cross-sectional study design, selected 315 persons (168 cafeterias, 96 dairy farms, and 51 milk vendors) for interview and collected the same number of bulk raw milk samples using systematic sampling procedure. Data were collected on socio-demographic, farm hygiene and milk handling practices by trained health professionals. Bacterial contamination was defined as total bacterial count (TBC) > 1 × 105, staphylococcus count (SC) > 105, or coliform count (CC) > 102 CFU/ml by culture and the species of bacteria were determined by standard biochemical tests. RESULTS: From the 315 milk samples tested, the prevalence of bacterial contamination was 52% (95% CI: 46.5-57.6). The mean counts of contaminated samples of TBC, SC, and CC were 8.94 ± 0.46 Standard Deviation (SD), 8.52 ± 0.6 SD, and 8.78 ± 0.49 SD log CFU/ml, respectively. The proportion of contamination was significantly lower in milk collected from dairy farms (32/96, 33.3, 95% CI: 24.5-43.2) compared to milk from vendors (33/51, 64.7, 95% CI: 51.4-66.2) and cafeterias (99/168, 58.9, 95% CI, 50.9-76.85). The milk samples were culture-positive for Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, K. oxytoca and Citrobacter freundii. CONCLUSIONS: Over half of the sampled raw milk exhibited bacterial contamination with increasing trend from farmers to points of sale. Thus, milk vendors and cafeteria owners should apply good hygienic and sanitation practices during handling of milk; use appropriate, clean containers, and cold chain during milk transportation; and refrigeration of milk during storage.

BACKGROUND: Fatigue is one of the most common and devastating Human Immuno-deficiency Virus (HIV) - related symptoms, with a varying prevalence in different study areas. In Ethiopia, there is a paucity of information on the magnitude and factors associated with fatigue among HIV/Acquired Immune Deficiency Syndrome (AIDS) patients. This may lead to under-diagnosis and eventually under-management of the symptom. METHODS: Institution based cross-sectional study design was conducted among 609 HIV/AIDS patients who were selected by using a systematic random sampling method. Data were collected by using interviewer administered structured questionnaire. Level of fatigue was measured by Fatigue Severity Scale. RESULTS: The prevalence of fatigue was found to be 51.7%. The factors associated with fatigue were: Parity [AOR = 2.01; 95% CI: 1.09-3.71], CD4 count 200-499 cells/mm3 [AOR = 2.81; 95% CI: 1.58-4.99], anemia [AOR = 4.90 95% CI: 2.40-9.97], co-morbidities [AOR = 3.65; 95% CI: 1.71-7.78], depression [AOR = 3.68 95% CI: 1.99-6.79], not being physically active [AOR = 3.20 95% CI: 1.50-6.81], clinical stage II or IV HIV [AOR = 3.11; 95% CI: 1.51-6.40] and [AOR = 4.08; 95% CI: 1.37-12.14], respectively. CONCLUSION: The finding of this study revealed that fatigue is a common health problem among adult People Living with HIV (PLHIV). Factors associated with fatigue included: Parity, CD4 count 200-499 cells/mm3, Clinical Stage II or IV HIV, anemia, co-morbidities, depression, and not being physically active. The health care service needs to address the predisposing factors by provision integrated care including timely detection and treatment of comorbidities, mental health problems, and promote physical activity to slow down disease progression and then reduce exposure to fatigue.

RESUMEN
BACKGROUND: Animal source foods provide high-quality protein and essential micronutrients within the human diet and are of particular significance for the health and development of children. Despite the availability of domestic livestock in rural households of Ethiopia, the diets of children are often monotonous and mainly cereal-based with low energy and nutrient density. OBJECTIVE: Explore barriers and facilitators for the consumption of animal source foods among 6-23 months old children from the rural communities of Northern Ethiopia. METHODS: A community-based exploratory qualitative study design was conducted in July through September 2018. A total of eight focus group discussions (56 individuals) and twenty-four qualitative interviews were conducted with mothers who are lactating, fathers, health extension workers, nutrition, and agriculture experts. Purposive sampling technique was used to include study participants based on their potential relevance in delivering a wealth of information. Thematic analysis strategies, a method for identifying, analyzing, and reporting themes within data, were used to code and grouped into related families and synthesize the qualitative data. RESULTS: Consumption of animal source foods among 6-23 months old children was very low and the home-reared livestock and their products were mainly used for market purposes. Animal products are consumed during special societal occasions since they are considered as luxury food rather than an essential part of daily children's diet. Lack of nutrition knowledge, high cost of animal source foods, mothers' workload to herd livestock, low household income, low milk production, the poor linkage between health and agriculture sectors, and social norms and beliefs were identified as common barriers. While the presence of nutrition experts, cooking demonstrations, in-kind credit programs, livestock ownership, and government-led stunting reduction programs were the facilitators for the consumption of animal source foods in the study communities. CONCLUSIONS: Reduced consumption of animal source foods inadvertently impacted dietary diversity of 6-23 months old children from the study communities. Thus, strengthening social and behavior change communication to promote the consumption of animal source foods, creating opportunities for women to own small livestock for household consumption and provide nutrition education on dietary restriction of animal source foods during religious periods among 6-23 months old children in the rural communities of Northern Ethiopia are recommended.

BACKGROUND: Globally in 2015 about 214 million malaria cases and 438,000 deaths were reported with 75% were from Sub-Saharan Africa. Malaria transmission in Ethiopia is unstable, and outbreaks are considered public health emergencies. Understanding the trigger for outbreaks in low-transmission areas can help facilitate malaria elimination. On July 8th malaria outbreak was reported from Laelay Adyabo district. The objective was to investigate the magnitude and associated factors with malaria outbreak. METHODS: We defined a case as confirmed malaria using microscopy or a rapid diagnostic test for Plasmodium parasites in a resident of Laelay-Adyabo District from July 9-28, 2017. We identified cases by reviewing health facility records and conducted a case-control study using randomly-selected cases from a line list, and two neighborhood controls per case. A pretested semi-structured questionnaire adapted from WHO malaria guidelines was used to collect data from case-patients and controls. We calculated crude (COR) and adjusted (AOR) odds ratios to identify factors associated with malaria. RESULT: A total of 145 confirmed malaria cases (57.9% males) were identified with village attack rate (AR) of 12.1/1000. The AR was higher among males than females (14.1 verses 10.1/1000), children aged 5-14 years (12.9/1000), and in Zelazle Kebelle (13.6/1000 population). Wearing protective clothing (AOR = 0.27, 95% CI 0.11-0.66), having good knowledge of malaria transmission (AOR = 0.25, 95% CI 0.08-0.75), having waste collection material at home (AOR = 0.25 95% CI 0.11-0.61), availability of mosquito breeding sites around home (AOR = 9.08, 95% CI 3.6-22.93), and staying outdoor overnight (AOR = 3.7, 95% CI 1.44-9.56) were independently associated with malaria. CONCLUSION: The overall attack rate for malaria during this outbreak was high affecting > 1% of the population. Wearing protective clothing at night, knowing about malaria transmission, having mosquito breeding sites around the home, staying outdoors overnight, and having waste collection material in their house were predictors of the infection. Laelay Adyabo district health office should provide health education on malaria transmission and prevention measures and how to clear mosquito breeding sites.

BACKGROUND: Population based prevalence survey is an important epidemiological index to measure the burden of tuberculosis (TB) disease and monitor progress towards TB control in high burden countries like Ethiopia. This study was aimed to estimate the prevalence of bacteriologically confirmed pulmonary tuberculosis (PTB) in the Tigray region of Ethiopia. METHODS: Sixteen rural and urban villages were randomly selected in a stratified multistage cluster sampling. Individuals aged 15 years and older were screened by symptom inquiry for PTB. Those individuals who were symptomatic of PTB provided two sputum samples for smear microscopy, culture and molecular typing. RESULTS: The study covering 4,765 households screened a total of 12,175 individuals aged 15 years and above. The overall weighted prevalence of bacteriologically confirmed PTB in the Tigray region of Ethiopia was found to be 216/100,000 (95% CI: 202.08, 230.76) while the weighted prevalence of smear-positive PTB was 169/100,000 (95% CI: 155.53, 181.60). The prevalence of bacteriologically confirmed TB was higher amongst males (352/100 000; 95% CI: 339.05, 364.52) than females (162/100 000; 95% CI: 153.60, 171.17) and among rural (222/100,000; 95% CI: 212.77-231.53) as compared to urban residents (193/100,000; 95% CI: 183.39-203.59). CONCLUSIONS: This study found a relatively higher prevalence smear-positive PTB in the region than in a same period nationwide survey and identified a significant number of undetected PTB cases. The urgency for improved TB case detection and intensified community awareness is emphasized.

BACKGROUND: Understanding the role of various determinants of tuberculosis (TB) is particularly important in countries like Ethiopia where TB is endemic and the resources available to public health intervention are limited However, little information is available on risk factors of TB to be able to effectively and efficiently control TB. OBJECTIVE: To identify and determine the potential host and environmental-related risk factors for development of active pulmonary tuberculosis (PTB) in the Tigray region of Ethiopia. METHODS: A matched case-control study was conducted from April-August 2011. Cases were defined as all newly diagnosed of PTB patients aged 15 years and above, who were registered by directly observed treatment short-course (DOTS) program health centers found in the randomly selected 16 districts in the region. Controls were age matched with no previous history of TB and chronic cough. For each case, two controls were recruited. Trained nurses collected data using structured and pre-tested questionnaire. Predictors of caseness were identified using conditional logistic regression method. Odds ratio were calculated with 95% confidence intervals to assess the strength of association. RESULTS: Data was collected from 463 cases and 860 controls. The mean age of the cases and controls were 37 +/- 14.9 and 39 +/- 14.5 years, respectively. In the multivariable analysis significant risk factors for active PTB were illiteracy (OR = 1.90, 95% CI: 1.24, 2.93), household food shortage (OR = 2.38, 95% CI: 1.52, 3.73), HIV seropositivity (OR = 2.7, 95% CI: 1.42, 5.13), and past alcohol consumption (OR = 2.44, 95% CI: 1.08, 5.50). Marriage (OR = 95% CI: 0.37, 0.89) was identified as protective factor. Consumption of raw milk, history of imprisonment, having a separate kitchen, history of asthma and history of TB contact were significant risk factors on crude analysis but their significance was not maintained in multivariable analysis. CONCLUSION: Our study results indicated that household food shortage, HIV sero-positivity, illiteracy, being married, smoking and alcohol consumption before six months have a substantially increased risk of developing tuberculosis, independent of other risk factors in adults in the Tigray region of Ethiopia. Hence, prevention and control efforts must target on this identified factors toward facilitating and effective and efficient TB control program in the study area.
