Food borne pathogens are major causes of deaths, illnesses and billions of dollars of expenses. The burden of food borne illness is worsened by the ever increasing rate of antimicrobial resistance microbes. Shigella, a bacterial pathogen associated with food, is reported to account for higher prevalence rates of food borne illness in different settings. A cross-sectional study was conducted from February 10 to June 30, 2013, at the butcher houses of Gondar town in the Northwest of Ethiopia to assess the prevalence and antimicrobial susceptibility pattern of Shigella. Cattle raw meat and swab samples from selected critical control points, including knives, chopping boards, and the hands and noses of butchers, were collected and analyzed. The identification of Shigella was carried out using colony characteristics, the Gram reaction, and biochemical tests. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disc diffusion method. The overall hygienic status of the butcher shops was also assessed using a checklist. An observational analysis revealed that the sanitary condition of the butcher shops and their premises was poor. Of 306 samples screened, 10.5% were positive for Shigella. Approximately 7.4% of meat samples and 10.2% of swab samples were contaminated with Shigella. Out of the total Shigella isolates, 90.6%, 46.9%, 18.8% and 9.4% were resistant to ampicillin, amoxicillin, ceftriaxone and tetracycline, respectively. A multidrug resistance pattern was recorded in 27.8% of the isolates. In conclusion, the safety of meat sold at Gondar butchers houses was poor. The identified Shigella isolates showed high levels of drug resistance and multidrug resistance patterns for commonly used antimicrobials in veterinary and human medicine. Practicing wise use of antimicrobials and strict sanitary interventions at different critical control points is strongly recommended, in addition to further in-depth studies to prevent unprecedented consequences from shigellosis.

Hepatitis B virus (HBV) quantification is essential in the management of chronic hepatitis B, both to determine treatment eligibility and in the monitoring of treatment effect. This test, however, is rarely available in resource-limited settings due to high costs and stringent requirements for shipment and storage of plasma. Dried Blood Spots (DBS) can be a convenient alternative to plasma, but its use for HBV monitoring has not been investigated under real-life conditions in Africa.The performance of DBS in HBV quantification was investigated using a modified commercial test (Abbott RealTime HBV assay). Paired DBS and plasma samples were collected from an HBV positive cohort in Addis Ababa, Ethiopia. DBS were stored at ambient temperature for 4-39 days before shipment to the laboratory.Twenty-six paired samples were selected covering the total range of quantification, from 2.14 log IU/ml to >7 log IU/ml. HBV was detected in 21 of 21 (100%) DBS from patients with a corresponding plasma viral load above 2.70 log IU/ml. The mean difference between plasma and DBS was 0.59 log IU/ml, and the correlation was strong (R2 = 0.92). In stability studies there was no significant change in DBS viral load after storage at room temperature for up to 12 weeks.This study suggests that DBS can be a feasible and reliable alternative to plasma for quantification of HBV in resource-limited settings. DBS can expand access to antiviral treatment for patients in low- and middle-income countries.

Despite declining global malaria incidence, the disease continues to be a threat to people living in endemic regions. In 2015, an estimated 214 million new malaria cases and 438,000 deaths due to malaria were recorded. Plasmodium vivax is the second most common cause of malaria next to Plasmodium falciparum. Vivax malaria is prevalent especially in Southeast Asia and the Horn of Africa, with enormous challenges in controlling the disease. Some of the challenges faced by vivax malaria-endemic countries include limited access to effective drugs treating liver stages of the parasite (schizonts and hypnozoites), emergence/spread of drug resistance, and misperception of vivax malaria as nonlethal. Primaquine, the only 8-aminoquinoline derivative approved by the US Food and Drug Administration, is intended to clear intrahepatic hypnozoites of P. vivax (radical cure). However, poor adherence to a prolonged treatment course, drug-induced hemolysis in patients with glucose-6-phosphate dehydrogenase deficiency, and the emergence of resistance make it imperative to look for alternative drugs. Therefore, this review focuses on data accrued to date on tafenoquine and gives insight on the potential role of the drug in preventing relapse and radical cure of patients with vivax malaria.

Task sharing mental health care through integration into primary health care (PHC) is advocated as a means of narrowing the treatment gap for mental disorders in low-income countries. However, the effectiveness, acceptability, feasibility and sustainability of this service model for people with a severe mental disorder (SMD) have not been evaluated in a low-income country.A randomised, controlled, non-inferiority trial will be carried out in a predominantly rural area of Ethiopia. A sample of 324 people with SMD (diagnoses of schizophrenia, schizoaffective disorder, bipolar disorder or major depressive disorder) with an ongoing need for mental health care will be recruited from 1) participants in a population-based cohort study and 2) people attending a psychiatric nurse-led out-patient clinic. The intervention is a task-sharing model of locally delivered mental health care for people with SMD integrated into PHC delivered over 18 months. Participants in the active control arm will receive the established and effective model of specialist mental health care delivered by psychiatric nurses at an out-patient clinic within a centrally located general hospital. The hypothesis is that people with SMD who receive mental health care integrated into PHC will have a non-inferior clinical outcome, defined as a mean symptom score on the Brief Psychiatric Rating Scale, expanded version, of no more than six points higher, compared to participants who receive the psychiatric nurse-led service, after 12 months. The primary outcome is change in symptom severity. Secondary outcomes are functional status, relapse, service use costs, service satisfaction, drop-out and medication adherence, nutritional status, physical health care, quality of care, medication side effects, stigma, adverse events and cost-effectiveness. Sustainability and cost-effectiveness will be further evaluated at 18 months. Randomisation will be stratified by health centre catchment area using random permuted blocks. The outcome assessors and investigators will be masked to allocation status.Evidence about the effectiveness of task sharing mental health care for people with SMD in a rural, low-income African country will inform the World Health Organisations mental health Gap Action Programme to scale-up mental health care globally.NCT02308956 (ClinicalTrials.gov).

Antiretroviral therapy (ART) is a lifesaving intervention for HIV infected children. There is a scarcity of data on immunological recovery and its relation with growth indicators among HIV infected young children. The current study aims to assess the pattern of anthropometric Z-score improvement following initiation of first-line ART among under-five children and the relationship between anthropometric Z-score improvement and immunologic recovery.We included under-five children who were on first-line ART at five major hospitals in Addis Ababa, Ethiopia. We measured anthropometry and collected clinical and laboratory data at follow up, and we retrieved clinical and anthropometric data at ART initiation from records. Z-scores for each of the anthropometric indices were calculated based on WHO growth standards using ENA for SMART 2011 software. Linear regression was used to assess the relationship between time on ART and anthropometric Z-score improvement; and the relationship between anthropometric Z-score improvement and immunologic recovery. Multiple linear regression was used to assess the independent predictors of anthropometric Z-score change.The median age of the participants was 4.1 (Interquartile range (IQR): 3.3-4.9) years. More than half (52.48%) were female. The median duration of follow up was 1.69 (IQR: 1.08-2.63) years. There was a significant improvement in all anthropometric indices at any follow up after initiation of first-line ART (underweight; 39.5% vs16.5%, stunting; 71.3% vs 62.9% and wasting; 16.3% vs 1.0%; p-value< 0.0001). There was an inverse relationship between improvement in weight for age Z-score (WAZ) and duration of ART (R2 = 0.04; F (1, 158); p = 0.013). Height for age Z-score (HAZ) both at the time of ART initiation and follow up has a positive linear relationship with CD4 percentage at follow up (Coef. = 1.92; R2 = 0.05; p-value = 0.002). Duration on ART (Std. Err. = 0.206, t = -1.99, p-value = 0.049) and level of maternal education (Std. Err. = 0.290, t = 2.64, p-value = 0.009) were the only independent predictors of the change in WAZ and change in HAZ at any follow up visit respectively.There was a significant improvement in all anthropometric indices at any follow-up after initiation of first-line ART among under-five children. HAZ was linearly related with immunologic recovery following ART initiation. The findings indicate that anthropometric indices could be taken as proxy indicators of immunologic recovery for under-five children.

Background: One way of addressing malnutrition among HIV/AIDS patients is through the Food by Prescription program (FBP) and many studies have explained the treatment outcomes after therapeutic food supplementation, though available evidences on adherence levels and factors associated with these sorts of programs are limited. The findings of this study would therefore contribute to the existing knowledge on adherence to Ready-to-Use Therapeutic/Supplementary Food (RUF) in Ethiopia.Methods: A facility-based, cross-sectional study supplemented with qualitative methods was conducted among 630 adult HIV + patients. Their level of adherence to RUF was measured using the Morisky 8-item Medication Adherence Scale (MMAS-8). The total score on the MMAS-8 ranges from 0 to 8, with scores of <6, 6 to <8, and 8 reflecting low, medium, and high adherence, respectively. Patients who had a low or a moderate rate of adherence were considered non-adherent.Results: The level of adherence was found to be 36.3% with a 95.0% response rate. With the exception of the educational status, other socio-demographic variables had no significant effect on adherence. Those who knew the benefits of the FBP program were 1.78 times more likely to adhere to the therapy than the referent groups. On the other hand, patients who were not informed on the duration of the treatment, those prescribed with more than 2 sachets/day and had been taking RUF for more than 4 month were less likely to adhere. The main reasons for non-adherence were not liking the way the food tasted and missing follow-up appointments. Stigma and sharing and selling food were the other reasons, as deduced from the focus group discussion (FGD) findings.Conclusion: The observed level of adherence to the FBP program among respondents enrolled in the intervention program was low. The major factors identified with a low adherence were a low level of education, poor knowledge on the benefits of RUF, the longer duration of the program, consuming more than two prescribed sachets of RUF per day, and not being informed about the duration of the treatment. Therefore, counseling patients on the program's benefits, including the treatment plans, would likely contribute to improved adherence. © 2014 Kebede and Haidar; licensee BioMed Central Ltd.

Objective To determine whether facility delivery is related to compliance with recommended infant immunizations, particularly those that occur weeks or months after delivery. Methods In a retrospective analysis, multivariate logistic regression was used to assess data from the 2011 Ethiopia Demographic and Health Survey (EDHS) to determine the strongest correlates of facility delivery. These correlates were then used, along with facility delivery itself, to determine the relationship between facility delivery and infant immunization. Results In total, 3334 women delivered a newborn 12-24 months before the 2011 EDHS: 90.2% (3007) delivered at home, and 9.8% (327) delivered in a facility. Education, wealth status, urban residence, and number of children under 5 years living in the household were the factors most strongly associated with facility delivery. When facility delivery and its strongest correlates were entered into multivariate logistic regression models with infant immunizations as the outcome, facility delivery was significantly associated with increased likelihood of DPT-HepB-Hib, polio, and measles vaccination, and increased likelihood of being fully immunized (all P < 0.01). Facility delivery was the strongest single factor associated with infants being immunized, doubling the odds of full immunization. Conclusion The impact of facility delivery on health outcomes transcends the immediate delivery and postpartum period. © 2013 International Federation of Gynecology and Obstetrics.

SETTING: St Peter Tuberculosis (TB) Specialized Hospital and the Aklilu Lemma Institute of Pathobiology, Addis Ababa, Ethiopia. OBJECTIVE: To genotype multidrug-resistant tuberculosis (MDR-TB) isolates and assess the magnitude of their clustering. DESIGN: A total of 183 consecutive MDR-TB isolates collected between September 2009 and February 2012 were characterised using molecular typing. Prior to the study, the isolates were confirmed as MDR-TB using GenoType® MTBDRplus. Recent transmission index was used to analyse the clusters. RESULTS: Spoligotyping identified 43 different patterns, of which 17 consisted of at least two isolates forming clusters, while 26 had only a single isolate. The most frequent patterns were spoligo international typing (SIT) number 21 and 149. Twenty-four patterns did not match existing patterns in the SpolDB4 database. The strains belonged to three lineages, the predominant lineages being Euro-American and Indo-Oceanic, each consisting of 65 isolates. High proportions (86%) of patients were infected with clustered strains, suggesting probable recent transmission of MDR-TB in the study area. CONCLUSION: The observation of cluster formation of the spoligotype patterns of MDR-TB isolates could suggest transmission of MDR-TB strains among the population, thus warranting further attention. © 2013 The Union.

As a very low-income country, Ethiopia faces significant development challenges, though there is great aspiration to dramatically improve health care in the country. Family medicine has recently been recognized through national policy as one potential contributor in addressing Ethiopias health care challenges. Family medicine is a new specialty in Ethiopia emerging in the context of family medicine development in Sub-Saharan Africa. The Addis Ababa University family medicine residency program started in 2013 and is the first and the only family medicine program in the country as of March 2016. Stakeholders on the ground feel that family medicine is off to a good start and have great enthusiasm and optimism for its success. While the Ministry of Health has a vision for the development of family medicine and a plan for rapid upscaling of family medicine across the country, significant challenges remain. Continuing discussion about the potential roles of family medicine specialists in Ethiopia and policy-level strategic planning to place family medicine at the core of primary health care delivery in the country is needed. In addition, the health care-tier system needs to be restructured to include the family medicine specialists along with appropriately equipped health care facilities for training and practice. Key stakeholders are optimistic that family medicine expansion can be successful in Ethiopia through a coordinated effort by the Ministry of Health and collaboration between institutions within the country, other Sub-Saharan African countries, and international partners supportive of establishing family medicine in Ethiopia.

Colostomy is one of the commonest life saving procedures done worldwide with an intention of either decompression of an obstructed colon or diversion of stool. Indications may vary from region to region. Attending morbidity and mortality is significant. the objective of this study was to Determine the common indications and types of colostomy, and outcomes of patients operated at SPHMMC.A retrospective medical records of patients, operation log book and nursing records review was done in a two-year period between January 2011 and December 2013 at the College Teaching Hospital, St Pauls Hospital Millennium Medical, Addis Ababa.During the two years, 253 colostomies were done and 219(86.6%) cases used for analysis. Of these, 151(68.9%) were males. Age ranged from 15 to 85 years with a mean of 50.8. Most of the surgeries, 196(89.5%), were done for emergency conditions. The three most common indications were gangrenous sigmoid volvulus, 102(46.6%), colorectal cancers, 46(21.0%, and abdominal injuries, 28(12.8%). The commonest type of colostomy done was Hartmans colostomy, 179(81.7.1%), gangrenous sigmoid volvulus being the predominant indication, 102(57%). Loop colostomy constituted 35(16%) of all the colostomies. Penetrating abdominal injuries was the main indication 15(42.9%). Overall, 157 complications were seen on 106(48.4%) patients. The most common complications were surgical site infection, 51(23.3%), hospital acquired pneumonia, (10.5%), and wound dehiscence, 17(7.8%). The mortality rate was 9.6% (21).Gangrenous sigmoid volvulus is the leading indication for colostomy. Mortality and morbidity rates are high. Aggressive resuscitation, early prompt operation and post op close follow-up should be emphasized.
