Abstract
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.

Abstract
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 3 %. 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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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 β-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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Background Monitoring the outcome of tuberculosis treatment and understanding the specific reasons for unsuccessful treatment outcome are important in evaluating the effectiveness of tuberculosis control program. This study investigated tuberculosis treatment outcomes and predictors for unsuccessful treatment outcome in the Tigray region of Ethiopia. Methods Medical records of smear-positive pulmonary tuberculosis (PTB) patients registered from September 2009 to June 2011 in 15 districts of Tigray region, Northern Ethiopia, were reviewed. Additional data were collected using a structured questionnaire administered through house-to-house visits by trained nurses. Tuberculosis treatment outcomes were assessed according to WHO guidelines. The association of unsuccessful treatment outcome with socio-demographic and clinical factors was analyzed using logistic regression model. Results Out of the 407 PTB patients (221 males and 186 females) aged 15 years and above, 89.2% had successful and 10.8% had unsuccessful treatment outcome. In the final multivariate logistic model, the odds of unsuccessful treatment outcome was higher among patients older than 40 years of age (adj. OR = 2.50, 95% CI: 1.12-5.59), family size greater than 5 persons (adj. OR = 3.26, 95% CI: 1.43-7.44), unemployed (adj. OR = 3.10, 95% CI: 1.33-7.24) and among retreatment cases (adj. OR = 2.00, 95% CI: 1.37-2.92) as compared to their respective comparison groups. Conclusions Treatment outcome among smear-positive PTB patients was satisfactory in the Tigray region of Ethiopia. Nonetheless, those patients at high risk of an unfavorable treatment outcome should be identified early and given additional follow-up and social support.

Abstract
Peste des petits ruminants (PPR) is a highly contagious animal disease caused by a virus in the genus Morbillivirus, family Paramyxoviridae. This infection is responsible for high morbidity and mortality in sheep and goats and in some small wild ruminant species. The huge number of small ruminants, which are reared in the endemic areas makes PPR a serious disease threatening the livelihood of poor farmers. Taking advantage of the closely relationship between rinderpest and PPR viruses, the attenuated rinderpest vaccine was used in the control of PPR. It is now replaced by the homologous attenuated PPR vaccine. Unfortunately, animals that have received this vaccine cannot be distinguished serologically from infected animals. With the advent of DNA recombinant technology, efforts are being made to develop effective PPR marker vaccines to enable such differentiation and which would allow countries to implement both vaccination and disease surveillance programmes at the same time.

Abstract
Sheep-pox and capripox are contagious diseases of domestic small ruminants for which the causal agent is a poxvirus classified into the Capripoxvirus genus. Viruses of this group have a host range specific to sheep, goats, cattle, and possibly buffalo. Thus, they are clearly indicated as vectors for the development of recombinant vaccines for peste des petits ruminants (PPR). Here we report the immune response of goats inoculated with a recombinant capripox-PPR hemagglutinin.

Abstract
The role of rapid health assessment in generating data other than routine reporting for a multi-element primary health care information system is presented. Rapid surveys, based on the adaptation of the WHO/EPI cluster survey methodology, may generate reliable and valid results useful for the support of a managerial PHC information system. However, because of the limitations inherent to the method, so far, only few studies have investigated more than few PHC related issues. The experience of a household rapid survey conducted in Arua District, Uganda, using a modified EPI cluster survey methodology, is reported. Rapid appraisal methods were used to prioritize the information requirement and to identify the survey items. Fully supervised teams of primary school teachers were used as interviewers. Data processing, check and analysis were speeded up by a lap-top computer, in spite of problems of erratic power. Within a 10-day time span between the start of the survey and the publishing of results, data on health services' utilization, health seeking behaviour, coverage of PHC services, including immunization, and anthropometric data on the nutritional status of under-five children were obtained. Standard errors and 95% confidence intervals were calculated taking into account the variability of the parameters under investigation and true design effects were computed. The findings were utilized for the identification of health priorities and the monitoring of effectiveness of programmes, as well as to validate routine reporting. The methodological package was built up looking at the local context, so that it could become an operational tool for the district health management team.
