Objective. The study objective was to estimate the burden of human rabies in Ethiopia from 2015–2019. Study Design. A descriptive study design was applied to measure the size of the problem. Method. Retrospective data were used from the Ethiopian Public Health Institute rabies case record book that was registered between 2015 to 2019. Result. Eighty-seven (87) cases of human rabies were diagnosed clinically in the Ethiopian Public Health Institute over the period of five years (2015–2019) with 100% case fatality. Of these, 83 (95.4%) cases were attributed to dog bites, whereas 1 (1.1%) to a cat and 3 (3.4%) to wild animals. The fatalities were from Oromia (n = 51 (58.6%), 13 (14.9%) were from Amhara, 15 (17.2%) were from Addis Ababa, and 8 (9.2%) from the Southern region. All referred cases had no record of immunization against rabies except eight. Ineffective postexposure treatment was the reason for 5 (5.7%) deaths. Out of 1,652 brain samples of different animals, mainly dogs, submitted for examination, 1,122 (68%) were found to be positive for rabies by the FAT. Dog bites were more common among males than females. The number of dog bite victims who had visited the EPHI counseling office and recommended to take postexposure prophylaxis against rabies both from Addis Ababa and the surrounding areas were 9,592 and 4,192, respectively. Out of these, 5,708 were males and 3,884 females for the capital Addis Ababa. Similarly, 2,439 males and 1,753 females account for areas surrounding Addis Ababa. Among those exposed from Addis Ababa, 1,079 (11.2%) were in the age group less than five, 1696 (17.7%) were in the age group 6–13, and 6,817 (71.1%) in the age group 14 and greater. Victims from outside of the capital Addis Ababa account for 644 (15.4%) for the age group less than 5 years, 964 (23%) for the age group 6–13 and, 2,584 (61.6%) for the age group 14 and greater. Conclusion. Mechanisms must be sought to reduce the cost of PEP and means of obtaining funds so as to initiate timely treatment for rabies exposed individuals of low socioeconomic status. Besides prevention, strategies should focus on public education and strict dog population control.

Texto completo da fonteResumo:
Hooded vulture (Necrosyrtes monachus) is an African endemic scavenger listed as Critically Endangered species. The population is declining across its range and there is threat of significant decline in population and distribution in Ethiopia. Little efforts have been made to properly document the status of vulture population and their diurnal activity patterns in the country for ensuring long term conservation measures. A study was conducted in Addis Ababa Abattoirs enterprise, Ethiopia from November 2019 to January 2020 to investigate the abundance and diurnal activity patterns of hooded vultures. The abundance of these vultures was estimated by direct counts method at their feeding sites and scan sampling was employed to study the diurnal activity patterns of hooded vultures from dawn to dusk. Hooded vulture mean abundance was 216±40 at the abattoir. Their diurnal activity pattern showed that they were observed feeding, resting (perching, watching and basking), preening, roosting and others activities such as walking, drinking, chasing and flying. They spent 37.73% of their time in resting followed by others (including walking, drinking, chasing and flying) (27.73%). The major threat recorded for theses vultures in the abattoir includes shortage of food, human disturbances, negative attitudes and lack of awareness on the importance of the species. Further ecological studies and impacts of human activities on Addis Ababa Abattoirs enterprise should be conducted for the conservation of hooded vulture and other conspecifics in the area.

Texto completo da fonteResumo:
The development of transport infrastructure is a priority objective for many African countries. This process has significant impact on the efficiency of continental and world trade corridors, and also influence on the costs of economic activity. In this case, the transformation in the transport sector of Ethiopia must be noted. The government of the country has taken a decision to create national railway network and develop aviation and road lines of communication. After The Eritrean War of Independence Eritrean separation was announced and Ethiopia lost its maritime infrastructure and became a landlocked country. This situation provides great difficulties in process of international trade and economic activity for the region. Now the development of transport corridors which connect economic centers with large ports of the region is a priority task for Ethiopian government. In this case Ethiopia is actively attracting foreign investors and world financial organizations to create stable, efficient and economically profitable ways of transport communication with the port infrastructure of neighboring countries. This year, Chinese companies finished to rebuilt the railway line Addis Ababa-Djibouti, in the coming years, governments of Kenya and Ethiopia, will launch new Mombasa-Nairobi-Addis Ababa motorway. This infrastructure projects are essential for enhancing Ethiopian competitiveness and economic activity and provide opportunity to reduce transport costs. Moreover, the Ethiopian authorities are making great progress in developing the internal transport infrastructure, first of all, in terms of increased paved road and development of railway infrastructure, which promotes more efficient use of natural,economic and human resources. Foreign companies are actively involved in realization of this transport projects and it can be a perspective area for cooperation between Russian Federation and Ethiopia. The article provides a detailed overview of Ethiopian transport sector and describes the key infrastructureprojects which can be interesting for Russian companies.

Background. Diagnosis using reliable tools and treatment followingin vitroantimicrobial susceptibility tests are critical to proper addressing of antibiotic-resistantSalmonellainfection.Methodology. A cross-sectional study was conducted to assess the practice of diagnosis and treatment of salmonellosis in Addis Ababa. Tube Widal test (for blood samples only), culture, biochemical and carbohydrate fermentation, serotyping, and antimicrobial susceptibility tests were employed for both blood and stool samples.Results. Of all the diseases listed in the diagnosis, nontyphoidal (n=72, 13.71%) and typhoidal (n=47, 8.95%) salmonellosis were the second and third common diseases. Among the 288 blood samples, almost half were positive for O, H, or both antigens. However, only 1 (0.68%) of the positive blood samples yieldedSalmonellaisolate during culture. The study demonstrated low specificity (0.68%) and positive predictive value (48.78%) of Widal test. Conversely, the test showed 100% sensitivity and negative predictive values.Salmonellaisolates were identified from 7 (7.07%) of 99 stool samples. Two-thirds of salmonellosis suspected patients received antibiotic treatment. However, only half of the confirmed salmonellosis patients were treated with appropriate antibiotics. All of the isolates were susceptible to ciprofloxacin and ceftriaxone but resistant to ampicillin.Conclusions. Majority of the patients who participated in this study were wrongly diagnosed using symptoms, clinical signs, and tube Widal test. Consequently, most of the patients received inappropriate treatment.

ABSTRACT Immunological values for 562 factory workers from Wonji, Ethiopia, a sugar estate 114 km southeast of the capital city, Addis Ababa, Ethiopia, were compared to values for 218 subjects from Akaki, Ethiopia, a suburb of Addis Ababa, for whom partial data were previously published. The following markers were measured: lymphocytes, T cells, B cells, NK cells, CD4+ T cells, and CD8+ T cells. A more in depth comparison was also made between Akaki and Wonji subjects. For this purpose, various differentiation and activation marker (CD45RA, CD27, HLA-DR, and CD38) expressions on CD4+ and CD8+ T cells were studied in 60 male, human immunodeficiency virus-negative subjects (30 from each site). Data were also compared with Dutch blood donor control values. The results confirmed that Ethiopians have significantly decreased CD4+ T-cell counts and highly activated immune status, independent of the geographic locale studied. They also showed that male subjects from Akaki have significantly higher CD8+ T-cell counts, resulting in a proportional increase in each of the CD8+ T-cell compartments studied: naı̈ve (CD45RA+CD27+), memory (CD45RA−CD27+), cytotoxic effector (CD45RA+CD27−), memory/effector (CD45RA−CD27−), activated (HLA-DR+CD38+), and resting (HLA-DR−CD38−). No expansion of a specific functional subset was observed. Endemic infection or higher immune activation is thus not a likely cause of the higher CD8 counts in the Akaki subjects. The data confirm and extend earlier observations and suggest that, although most lymphocyte subsets are comparable between the two geographical locales, there are also differences. Thus, care should be taken in extrapolating immunological reference values from one population group to another.

Processing changes the meat ecosystem and, hence, has an impact on the microbiological load and quality of the product. Microbial contamination decreases shelf life and, if a pathogen is present, increases the risk of zoonoses in humans. The aim of this study was to assess the microbiological load, including zoonotic agents, in ready-to-eat beef mortadella from Ethiopian supermarkets. A total of 119 samples from 8 supermarkets in Addis Ababa City (Ethiopia) were examined for aerobic plate count, Enterobacteriaceae, Salmonella, and Escherichia coli. An overall mean of 4.0 log for aerobic plate count and 2.2 log for Enterobacteriaceae was observed. The Salmonella prevalence was 0.8%. An overall E. coli prevalence of 29% (range, 13 to 53%) was observed at individual supermarkets.

Texto completo da fonteResumo:
Humans have shaped carnivore behavior since at least the Middle Paleolithic period, about 42,000 years ago. In more recent times, spotted hyenas (Crocuta crocuta) in Ethiopia have adapted to living in urban areas, while humans have adapted to living with hyenas. Yet, relationships between coexisting humans and carnivores are rarely addressed beyond mitigating conflicts. We provided a case study for how to broadly think about coexistence and how to study it when measuring if humans and carnivores affect one another. We collected data in four Ethiopian cities: Mekelle, Harar, Addis Ababa, and Arba Minch. We held focus groups and key informant interviews that incorporated feedback from 163 people, representing a wide array of religious, economic, and educational backgrounds. We also determined how many hyenas resided in these cities, hyena behavioral responses to humans using a flight initiation test, and problem-solving abilities via puzzle box trials. We found that in three of the cities, hyenas and humans coexist at high densities and frequently encounter each other. While all participants recognized the importance of hyenas as scavengers to maintain a clean environment, there was pronounced variation in cultural perspectives across cities. For example, while the people of Harar revere hyenas in spiritual terms, in Arba Minch hyenas were regarded as nuisance animals. Hyenas were universally respected as a formidable predator across cities but reports of attacks on livestock and humans were few. Flight initiation tests revealed hyenas fled at significantly closer distances in Harar and Addis Ababa than in Mekelle. Hyenas succeeded at solving a puzzle box in Harar but not in Mekelle. These variable behavior in hyenas correlated to different human perceptions. Our case study results suggest that the hyena–human dynamic is highly variable across these locations. We conclude by exploring the implications of these findings for how humans and hyenas can shape one another’s behavior. Developing studies to link human perceptions and animal behavior could advance wildlife conservation, especially in urban areas.

Texto completo da fonteResumo:
Water security is a global concern because of the growing impact of human activities and climate change on water resources. Studies had been performed at global, country, and city level to assess the water security issues. However, assessment of water security at a domestic scale is lacking. This paper develops a new domestic water security assessment framework accounting for water supply, sanitation, and hygiene through twelve indicators. Water supply, sanitation, and hygiene are central to key water-related sustainable development goals. The framework is subsequently applied to the city of Addis Ababa, Ethiopia. From the domestic water security assessment of Addis Ababa, the water supply dimension was found to be of good level, whereas the sanitation and hygiene dimensions were of poor and fair level, respectively, indicating both a challenge and an opportunity for development. Because the analysis is spatially explicit at the city-branch level (in Addis), variation in domestic water security performance across Addis Ababa can be assessed, allowing efficient targeting of scant resources (financial, technical, personnel). Analysis further shows that a lack of institutional capacity within the utility, existing infrastructure leading to ‘lock-in’ and hindering maintenance and upgrade initiatives, and an unreliable power supply are the main issues leading to poor domestic water security in the study city. These areas should be tackled to improve the current situation and mitigate future problems. The developed framework is generic enough to be applied to other urban and peri-urban areas, yet provides planners and policy makers with specific information on domestic water security considering water supply, sanitation and hygiene, and accounting for within-city variability. This work could therefore have practical applicability for water service providers.

Due to the turbulent of business environment, complexity of managing human resource and volatility of customer needs, it is a formidable managerial task to design structures which will be suitable to meet such requirements and free to exercise course of action for managerial discretion. However, in most of the case the structure type that can be designed and implemented in many organizations are to the interest of stakeholders and owners. Research also shows that the latitudinal action of management staffs and autonomous decisions are a theme of discussion in managerial discretion. The researcher used a conceptual study of both a qualitative and quantitative approach coupled with case study for this study. Based on the study, the research findings show that organizations that have managed by owner-manager has less experienced managerial discretion, and thereby came to conclude that managers who are free to choose course of action have led to company success than those company which managed by owner-manager.

Purpose The purpose of this paper is to empirically test whether enforceability mediates the relationship between property rights and investment in housing, using data from land formalization project in Addis Ababa, Ethiopia. Design/methodology/approach The study was cross-sectional in design; data were collected from a sample of 210 households that benefited from the recent Addis Ababa city land and buildings formalization project. Confirmatory factor analysis was used to assess the goodness-of-fit of the latent structures underlying the constructs. Mediation was tested using the Baron and Kenny steps, combined with bootstrapping technique. Robustness of results was checked. Findings The results indicate statistically significant mediation effect of contract enforcement. However, the mediation is partial, there is still a substantial direct effect of security of property rights on investment. Practical implications Any initiative to land formalization projects needs to consider contract enforcement environment, as presence and size of property rights effects largely depend on whether those rights are properly enforced. Originality/value This is the first study that conceptualizes the mediating effect of contract enforcement on the relationship between property rights and investment from an African country perspective.

To quantify the risk of human immunodeficiency virus (HIV) infection in children with tuberculosis (TB) a hospital-based, 1-year prospective, case-control study was performed in Addis Ababa, Ethiopia. Children with TB were compared to a control group of children admitted for elective surgery. The control group was also compared to a recent census of the background population. The crude odds ratio for HIV infection was 8·6 (95% CI 2·2–73). After adjustment for possible confounders in a multivariate regression model, the odds ratio for HIV infection in children with TB was found to be 12·7 (95% CI 2·9–55). Of several independent determinants of TB assessed in the study, this association was the strongest. Until HIV transmission has reached its peak, an increasing burden of dual infection among Ethiopian children is to be expected.

This study aimed to assess the prevalence and associated factors of depressive symptoms among youth living with Human Immunodeficiency Virus (HIV) attending Antiretroviral Therapy (ART) follow-up at public hospitals in Addis Ababa, Ethiopia.Objective. To assess the prevalence and associated factors of depressive symptoms among youth living with Human Immunodeficiency Virus (HIV) attending Antiretroviral Therapy (ART) follow-up at public hospitals Addis Ababa, Ethiopia, 2016.Method. In a cross sectional study, 507 HIV-positive young people from public health hospitals were recruited by systematic random sampling technique. Beck Depression Inventory-II was used to assess depressive symptoms. Morisky medication adherence rating scale, social support rating scale, and HIV stigma scale were the instruments used to assess the associated factors.Results. Prevalence of depressive symptoms among HIV-positive youth was 35.5% (95% CI:31.3, 39.6). In multivariate analysis, age range between 20 and 24 years with (AOR=2.22, 95% CI: 1.33,3.62), history of opportunistic infection (AOR=1.94, 95% CI:1.15,3.27), poor medication adherence (AOR=1.73, 95%CI:1.13,2.64, low social support (AOR=2.74, 95%CI:1.13,2.64), moderate social support (AOR=1.75 95% CI: 1.03,2.98), and stigma (AOR=2.06, 95% CI: 1.35,3.14) were associated with depressive symptoms. The results suggest that prevalence of depressive symptoms among HIV-positive youth was high. Prevention of opportunistic infection, stigma, and counseling for good medication adherence are necessary among HIV-positive youth.

Abstract Human beings could be exposed to impacts associated with heavy metals such as lead (Pb) through drinking water. The objective of this study was to evaluate quality of water consumed by kindergarten school children in Addis Ababa city, who are highly susceptible to issues related to heavy metals in water. Through conducting chemical analysis, using microwave plasma atomic emission spectrophotometry (MP-AES), the level of lead (Pb) was measured at 38 selected schools in the city. Drinking water samples were taken from three water supply sub-systems: Akaki, Legedadi, and Gefersa. Results revealed the average Pb concentration in the city was 62.37 μg/L which is significantly higher than the World Health Organization (WHO) recommended threshold value of 10 μg/L. The children's blood lead levels and exposure to Pb were also calculated using the integrated exposure uptake bio-kinetic (IEUBK) model as per USEPA guidelines. Estimated geometric mean blood lead levels (BLLs) for each school ranged from 4.4 to 13.2 μg/dL. On average, the model predicted that 20% of children in the city will have blood lead levels above the WHO recommended 10 μg/dL. The study can be considered as an unprecedented piece of work as it addresses critical issues and methods to mitigate problems caused by high concentration of Pb in water supply distribution infrastructure.

Salmonellais one of the top causes of foodborne bacterial illnesses in humans. The primary sources of humanSalmonellainfection are food producing animals such as cattle, poultry, and swine. A cross-sectional study was undertaken to estimate the prevalence and to determine the serovar distribution and antimicrobial susceptibility profiles ofSalmonellaspp. isolated from fecal (n=567) and carcass swab (n=159) samples of slaughtered cattle at Addis Ababa Abattoir Enterprise and Kara’alo PLC, Abattoirs, in Addis Ababa, Ethiopia between January 2014 and April 2015.Salmonellaisolation was conducted according to Global Foodborne Infections Network Laboratory Protocol and isolates were confirmed by genus specific PCR and serotyped by slide agglutination test. Susceptibility of the isolates to 17 antimicrobials was testedusing the Kirby-Bauer disk diffusion method according to the guidelines of the Clinical and Laboratory Standards Institute. Out of the total 726 samples examined, 27 (3.7%) were positive forSalmonella. Salmonellawas detected in 4.1% (23/567) fecal and 2.5% (4/159) carcass swab samples. Twelve different serovars were identified and the most predominant serovars wereS. Dublin (n=10, 35.7%) andS. Virchow (n=5, 17.9%), followed byS. Braendrerup,S. Haifa, andS. Saintpaul which were isolated from 2 samples each (7.1%). All of theSalmonellaisolates investigated were resistant or intermediately resistant to four or more of the 17 drugs tested. High resistance rate was recorded to streptomycin 25 (89.3%), cephalothin 20 (71.4%), ampicillin 19 (67.9%), and amoxicillin+clavulanic acid 19 (67.9%). Resistance to five or more antimicrobials was detected in 20 (71.5%) of the isolates. Multidrug resistance to more than 7 antimicrobials was detected in 5 (17.9%) of the isolates. Isolation of such multidrug resistant strains ofSalmonellafrom slaughtered cattle poses a major public health concern. These findings imply the need for a strict biosecurity and regulation of antimicrobial use across the country.

Aims: Blindness is a bane to humanity globally, and living with blindness is a challenge to anyone – young or old, educated or uneducated, rich or poor. Many countries have high rates of blindness, and Ethiopia is one. The study aims to explore the level of resilience, the extent of risk, and protective factors operating upon blind adolescents in Addis Ababa. Background: Resilience can significantly impact the quality of life of humans. Risk-taking and protective factors found in one's environment are significant predictors of resilience, valid even for the blind. The study intends to explore the level of resilience, the extent of risk, and protective factors operating upon blind adolescents in Addis Ababa. Objectives: The objectives identified for the study are: • To assess the risk and protective factors operating upon Adolescents With Blindness (AWB) and establishing the pattern with which risk factors and protective resources relate to each other and predict resilience. • To investigate the way the type of onset of blindness and some selected demographic variables relate to resilience among AWB. Methods: Data for the study were collected randomly from 80 blind adolescents using the Connor-Davidson Resilience Scale, Risk Factors Scale Adolescent Form, and Protective Factors Scale-Adolescent Form. The data were analyzed with t-test, one-way ANOVA, and multiple linear regression. Results: Low levels of resilience, presence of higher risk factors and serious lack of protective resources existed among AWB. While risk factors were negatively correlated with resilience, protective factors correlated with resilience positively. The risks and protective resources found in various levels of the environment together accounted for 89.3% of the variance in resilience. Gender, time of onset of blindness, parental education and family income influenced resilience. Conclusion: This study presents an all-inclusive picture of the resilience status of AWB’s, the extent of risk and protective factors currently operating upon them under the present context of Addis Ababa. Adolescents having blindness currently living in Addis Ababa are less resilient. They are faced with umpteen risk factors at home, school, neighborhood, community and societal levels.

Abstract Despite the quick urban population growth increased volume of wastes, including human excreta, which demands an expanded need of infrastructure, solid institutional setup and communities' engagement for management of safe disposal of excreta, arrangement of such basic social services has not developed as per the rate of population growth. Mostly, communal latrines are inclined towards an absence of cleanliness, as they accommodate many people beyond their capacity, filling up septic tanks quickly. A community-based cross-sectional study conducted in 817 randomly selected communal latrine user households, five focus group discussions and four key informant interviews were analysed. Bivariate and multivariate logistic regression analysis was performed to discover the impact of different factors on the use of communal latrines. The findings revealed that the rate of communal latrine use in Addis Ababa was about 79.8%. Unhygienic conditions, latrine emptying challenges, extreme smell, number of family units sharing the same squats, and latrine designs for the aged and children were identified as barriers to latrine utilization. This study suggests that, in parallel with the continued investments to increase access to sanitary facilities in the city, the management and behavioural change part has likewise to be stressed for better use and sustainability.

Texto completo da fonteResumo:
Subclinical human cytomegalovirus (HCMV) replication is associated with immune dysfunction in immuno-suppressed antiretroviral therapy (ART) naive HIV infected individuals. No data is documented in Ethiopia so far concerning HCMV co-infection among HIV infected individuals. Hence, this study was aimed at generating data regarding the prevalence of active HCMV infection among treatment-naive HIV-infected individuals from Ethiopia. For this purpose, we enrolled 97 treatment-naive HIV infected study subjects in Addis Ababa from June to December 2018. ELISA and conventional PCR were performed consecutively to detect HCMV specific IgM antibody and HCMV DNA respectively. Of the 97 study subjects, 12 (12.4%) were positive for anti-CMV IgM antibodies but were not confirmed by PCR. With regard to the PCR positivity, 4/97 (4.1%) samples were positive for HCMV DNA. No statically significant associations were found between the dependent and independent variables. The presence of HCMV DNA in the current study highlights the need for a routine laboratory diagnosis for preventing HCMV disease among HIV-infected individuals early. Besides, the use of anti-CMV therapy for these CMV viremic individuals is also recommended as this can reduce the burden of CMV complications and consecutively prolonging the life of HIV infected individuals.

Introduction: Salmonella has been reported from foods and the food production environment, with outbreaks occurring in the human population worldwide. Methodology: A survey on Salmonella in two beef production lines (a beef abattoir line and a processing line) in Addis Ababa, Ethiopia was conducted, with a total of 668 various samples randomly collected from animal-related materials, the environment, and a beef product (mortadella). Results: Overall, a 12.9% prevalence (26.3% from the abattoir line, 5.3% from the processing plant line) was observed. The prevalence in the abattoir line environment (36.6%) was higher than that in animal-related samples (14.7%); the reverse was true for the processing plant line. Out of 86 isolates, 10 serovars were identified, and 8 remained unidentified. The predominant serotypes were S. Saintpaul (32.5%), S. Muenchen (19.8%), and S. Larochelle (12.8%). S. Kastrup and S. London were isolated for the first time in Ethiopia. Conclusions: Data indicate open ports of entry for Salmonella, with possible transfer along the line. Further investigations from farm to fork are recommended in order to identify these positions of entry.

The main purpose of this article was to investigate the link between human resource training and development, employee commitment and job satisfaction, and the moderation role of the work environment. The quantitative research design was adopted using 212 valid questionnaires that were filled by selected private banks in Addis Ababa, Ethiopia using a convenience sampling technique. To validate the factor structure of the observed variables confirmatory factor analysis was applied and Structural Equation Modeling was used to test the hypothesized relationship. The results showed that training and development positively relate to organizational employee commitment and employee job satisfaction of workforces, while the work environment positively moderates this relationship. This implies that investing in human resource training and development positively affects the employee’s commitment to the organization and enhances their satisfaction. The more the work environment is conducive the better the relationship between the study variables. Finally, the implication, limitations, and future studies were discussed.

Texto completo da fonteResumo:
Bovine brucellosis is an infectious bacterial disease caused by members of genus Brucella, affecting both animals and humans, and resulting in a serious economic loss in animal production sector and deterioration of public health. A cross-sectional study was conducted from November 2014 to April 2015 to determine the seroprevalence and associated risk factors of bovine brucellosis in Sendafa, Oromia Special Zone, Ethiopia. A total of 503 blood samples were collected using a simple random sampling technique from dairy cattle of above 6 months of age with no history of previous vaccination against brucellosis. All sera samples were subjected to both Rose Bengal Plate Test for screening and Complement Fixation Test for confirmation. Accordingly, the overall seroprevalence of bovine brucellosis in the study area was 0.40%. The result showed that the seroprevalence of bovine brucellosis in the study area was not statistically significant with all proposed risk factors. No reactors were observed in male animals. The seroprevalence was observed in animals without previous history of abortion. Moreover, information was gathered on individual animal and farm-level risk factors and other farm characteristics using a questionnaire. Awareness among society was poor, so the positive animals can be a potential hazard to animals and humans in the study area. Therefore, public education should be done to improve the awareness of the community on bovine brucellosis and its public health impact with due consideration on the safe consumption of food of animal origin.

Texto completo da fonteResumo:
In developing countries, widely reported incidents of dangerous levels of pesticides in food have stimulated the demand for organic food, a movement to choose organic agriculture. It also makes more people have desires to consume chemical free foods. This study, therefore, assessed the consumers’ awareness of their eight basic rights and willingness to pay for organic vegetables in Ethiopia. The data were collected from 200 respondents (consumers) from Addis Ababa and 80 smallholder vegetable farmers at Ziway and Meki through a combination of random and purposive sampling procedures using a structured interview and were analyzed using descriptive analysis. The results show that vegetable producers used a lot of chemicals, but not in a safe way or at the optimum level. The findings also show that the overall degree of consumers’ awareness on the eight consumer rights is low. Furthermore, willingness to pay premium prices about 5-50% to obtain organic products, which can be viewed as the cost of investment in human health, is encouraging. There is a need to target agricultural policies relating to handling practices and for public health policies to be more differentiated in promoting food safety. Informing consumers about unique characteristics of organic production methods, the strict inspection and required third party certification might be a promising strategy to develop the market for organic vegetables in Ethiopian urban centers.

Texto completo da fonteResumo:
Introduction: The knee joint, the largest joint in the body, has several functions which are essential for human beings to walk, run and jump. Primarily, it enables flexion-extension of the lower limb in the sagittal plane. Joint stability during movement is attained by the shape of the articular surfaces, the collateral and cruciate ligaments, the menisci and tendons and muscles crossing the knee joint. (1) The vulnerability of the knee, the largest joint in the body, to direct trauma makes knee injuries very common throughout life. (2)
MRI visualizes most components of the knee joint, including articular cartilage, menisci, intra-articular ligaments, synovium, bone marrow, subchondral cysts, and other periarticular and intra-articular lesions that are not detectable by radiography. (4).
The prevalence of abnormalities of these different joint components as detected by MRI has been studied in different centers. Such types of studies, to date, have not been done in our country to our knowledge. The aim of this paper is to study prevalence of these abnormalities in the knee joint detected by knee MRI.
Objective: To assess the prevalence of abnormalities in the knee joint detected by knee MRI.
Methods: Hospital based prospective cross sectional study was conducted on 49 patients who had knee MRI at Tikur Anbessa Specialized Hospital in a period of 7 months from January 1 to August 2016. Patients included here are those who had knee MRI and no history of knee surgery.
Results: A total of 49 patients were included in the study out of which 26(53.1%) were male and 23 (46.9%) were female, with a mean age of 43 years (range 17 to 68 years). The three most common pathologies were joint effusion seen in 32(65.3%), bone marrow edema in 22(45.8%) and osteophytes in 22(44.9%). ACL tear was the commonest ligament abnormality occurring in 5 (10.4%) patients. Ten (20.8%) patients had meniscal tear, all involving the medial meniscus with the posterior horn being involved in 8(80%) of these patients.
Conclusion: The mean age of our study population was higher than most referenced papers suggestive for possible delayed health seeking. The commonest knee pathologies were similar to other studies. Features of osteoarthritis were seen in higher frequency in our study population. Even though the higher mean age could be the possible cause, further study is recommended to look into the causes. Abnormalities which were seen with higher frequency in those with a history of trauma were also seen in higher frequency in the male population.

Texto completo da fonteResumo:
Background. Needlestick and sharp injuries are a big risk to the health of nurses. Every day, nurses face the likelihood that they will injure themselves. Although many injuries will have no adverse effect, the possibility of acquiring infections like hepatitis C virus, hepatitis B virus, and human immunodeficiency virus can cause untold psychological harm. Nurses are in danger of injuries caused by needlestick and sharp instruments in hospitals. Objective. The objective of this study was to assess the magnitude and determinants of needlestick and/or sharp injuries among nurses working at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, 2018. Methods. An institution-based cross-sectional study was conducted among 268 nurses working at Tikur Anbessa Specialized Hospital from February to March 2018. A stratified random sampling technique was used to select the study participants. Data were collected using a self-administered questionnaire. A bivariate and multivariate logistic regression model was fitted to spot factors associated with needlestick and/or sharp injury. An adjusted odds ratio with a 95% confidence interval was computed to determine the level of significance. Result. The prevalence of needlestick and/or sharp injuries among nurses was 36.2% (95% CI 30.2%, 42.3%). Presence of contaminated needles and/or sharp materials in the working area ( AOR = 2.052 (95% CI 1.110, 3.791)), needle recapping after use ( AOR = 1.780 (95% CI 1.025, 3.091)), working in the pediatric ward ( AOR = 0.323 (95% CI 0.112, 0.930)), and being female ( AOR = 0.461 (95% CI 0.252, 0.845)) were significantly associated with needlestick and/or sharp injury at p value of ≤0.05. Conclusion and Recommendation. The proportion of needlestick and/or sharp injury was high among nurses. The safety of nurses depends directly on the degree to which nurses can identify and control the numerous occupational hazards specific to jobs. Thus, working unit specific safety precautions, a safe working environment, and appropriate needle and sharp disposal improve nurses’ safety practices and thereby decrease the injuries.

Background. This systematic review aimed at examining the use patterns of Ethiopian anticancer traditional medicinal plants (MPs) in view of recommending further validation studies.Methods. The information was retrieved from PubMed according to the PRISMA guideline. The electronic library of Addis Ababa University and relevant church-based religious books were also inspected for additional data.Results. From 34 studies meeting specific inclusion/exclusion criteria, 119 anticancer MP species distributed in 98 genera and 57 families were recorded. Fabaceae (10.92 %) and Euphorbiaceae (10.08 %) were the most widely used families.Plumbago zeylanica(Plumbaginaceae) was the most frequently used anticancer MP species. Shrubs (42.02 %) and herbs (35.29 %) were dominant growth forms. About 89.08 % of the MPs were collected from wild habitats. Leaves (33.73 %) and roots (27.11 %) were the most frequently harvested parts. The most favored routes were dermal (33.33 %) and oral (29.25 %). About 87.07 % preparations were made from fresh plant materials. Breast cancer and skin cancer were treated with 14 % and 10.76 % of anticancer MPs, respectively.Conclusion. The review showed that anticancer MPs are widely used across the regions of Ethiopia. Most of the MPs are not scientifically experimented and yet are at a higher vulnerability to loss mainly by human activities. Calling for conservation measures, we recommend experimental validation of the frequently used anticancer MPs. This augments global anticancer drug researches.

Introduction Nutritional management is a fundamental practice of concern to all patients infected with the human immunodeficiency virus (HIV). The nature of HIV/AIDS and malnutrition impacts are interlocked and intensify one another. Objective This study aimed to explore nutrition management challenges among people living with HIV on antiretroviral therapy (ART) in primary health centres in Addis Ababa, Ethiopia. Methods and materials We used a hermeneutic (interpretive) phenomenological study design. The study used in-depth interviews to describe lived experiences among adult patients aged 18 and above. We selected the participants purposively until the saturation of the idea reached. We maintained the scientific rigor and trustworthiness by applying credibility, transferability, dependability, and conformability, followed by translation and re-reading of the data has been achieved. The data have been analyzed through inductive thematic analysis assisted by NVIVO version 12 pro software. Result Nutrition management challenges for HIV patients have been described using six significant themes. The major themes were: acceptance of the disease and the health status; facilitators and barriers to treatment adherence; behavioural changes in eating patterns; experience of food insecurity issues; nutrition knowledge; and support. The themes have explained how patients using ART have been challenged to manage their nutrition ever since their diagnosis. Of all challenges, food insecurity is found to be the core reason for poor nutrition management. Conclusion and recommendation We found that many factors in managing their nutrition challenged patients with HIV. There should be an increasing interest in managing food insecurity issues as food insecurity has been strongly related to other factors.

Plant tissue culture (PTC) is one of the well-adapted and practiced biotechnology tools in Ethiopia. After the initial success of tissue culture at the Ethiopian Institute of Agriculture Research and Addis Ababa University, the technology spread its roots to most of the research institutes and universities across the country. Consequently, the technology continues to extend at the commercial level. However, there is a lack of information at the national level on the capacity of national institutes in terms of available infrastructure and skilled human power, the potential of the laboratories for tissue culture-related activities, and existing challenges that hinder tissue culture research and development. This study aimed to assess the status of tissue culture research and development in Ethiopia and identify gaps that hinder its application in various economic sectors. The primary data were collected from 19 tissue culture laboratories across the country using questionnaires and physical observation. Accordingly, the results of the study revealed that Jimma Agricultural Research Center from the federal research institute and Amhara Regional Agriculture Research Institute, Bahir Dar Laboratory, from the regional research institute are relatively well equipped with facilities and equipment for tissue culture R&D activities. Among the commercial laboratories, Tigray Biotechnology Center is well equipped and has the highest production capacity with 40 million seedlings per year. Besides, the assessment revealed that a total of 54 plant species have been under in vitro protocol optimization and development process across all PTC laboratories. Nevertheless, tissue culture application in public and private sectors in Ethiopia is limited by several technical, administrative, and financial constraints. Therefore, to exploit the maximum benefit of PTC technology in the existing facilities, further intervention is critical in solving the identified challenges.

Salmonellae are ubiquitous, found in animals, humans, and the environment, a condition which facilitates transmission and cross contamination. Salmonella enterica serotypes exert huge health and economic impacts due to their virulence or carriage of antibiotic resistance traits. To address this significant issues with regard to public health, availability of adequate information on the prevalence and antibiotic resistance patterns of Salmonella, and establishment of adequate measures to control contamination and infection are needed. A cross-sectional study was conducted to assess the level of Salmonella infection in slaughtered bovines and ovines at Addis Ababa abattoir. Samples were collected randomly and processed for identification and antimicrobial susceptibility testing of Salmonella spp. From 280 animals examined, 13 (4.64%) (8 bovines and 5 ovines) were positive, with most samples (12/13, 92%) comprising Salmonella Dublin. Very high level of resistance to some antibiotics used in human medicine was detected. Most isolates were susceptible to gentamycin and amikacin. Nine (69%) of all isolates were resistant to multiple antibiotics. Serotyping revealed 12 of 13 isolates to be of the Dublin serotype with 9,12:g,p:- antigenic formula. This study emphasizes the importance of improving the evisceration practice during slaughtering and restricting the use of antibiotics in farm animals.

Diabetes mellitus (DM) is a severe chronic disease that affects human health and has a high prevalence worldwide. Research has shown that half of the diabetic people throughout the world are unaware that they have DM and its complications are increasing, which presents new research challenges and opportunities. In this paper, we propose a preemptive diagnosis method for diabetes mellitus (DM) to assist or complement the early recognition of the disease in countries with low medical expert densities. Diabetes data are collected from the Zewditu Memorial Hospital (ZMHDD) in Addis Ababa, Ethiopia. Light Gradient Boosting Machine (LightGBM) is one of the most recent successful research findings for the gradient boosting framework that uses tree-based learning algorithms. It has low computational complexity and, therefore, is suited for applications in limited capacity regions such as Ethiopia. Thus, in this study, we apply the principle of LightGBM to develop an accurate model for the diagnosis of diabetes. The experimental results show that the prepared diabetes dataset is informative to predict the condition of diabetes mellitus. With accuracy, AUC, sensitivity, and specificity of 98.1%, 98.1%, 99.9%, and 96.3%, respectively, the LightGBM model outperformed KNN, SVM, NB, Bagging, RF, and XGBoost in the case of the ZMHDD dataset.

Background : Body temperature is a vital sign and 37°C is the mean core body temperature of a healthy human. Core body temperature is normally tightly regulated and maintained within narrow range. Perioperative hypothermia is one of the major problems during surgery and anesthesia that can affect operated patients. Methods: Institutional based cross-sectional study was conducted. Patient interview, chart review and temperature measurement were employed for data collection. Temperature was measured using tympanic membrane thermometer. SPSS version 20 software was used for analysis. binary logistic regression was used to look at associations anda p-value of <0.05 was considered statistically significant.
Result :The overall magnitude of preoperative, intra and post-operative hypothermia in this study was 16.2%, 53.2% and 31.3%, respectively. Age (AOR=7.15, 95% CI, 1.16, 43.99), coexisting illness (AOR, 3.32, 95% CI, 1.06; 10.36), preoperative hypothermia (AOR; 57; 95% CI; 7.1, 455.4), operation room temperature (AOR=1.91; 95 % CI, 1.04; 3.5) and crystalloid fluids administered (AOR; 2.3; 95% CI, 1.07, 4.9) were found to be factors associated with intraoperative hypothermia.
Conclusion and recommendation: The magnitude of perioperative hypothermia remains high. Measures should focus on improving room temperature and warming up fluids. Susceptible patients like the aged and those with coexisting disease should be given extra attention.

Texto completo da fonteResumo:
Staphylococcus aureus is a contagious pathogen that can cause various diseases in both humans and animals. Antimicrobial-resistant S. aureus is becoming an extremely important global health problem. A cross-sectional study was conducted from December 2019 to May 2020 to assess the occurrence of S. aureus and its antimicrobial susceptibility profiles in milk and traditionally processed dairy products in selected subcities of Addis Ababa. A total of 255 dairy product samples (175 raw milk and 80 traditionally processed dairy products) were collected from farms and retail markets. Samples were cultured for S. aureus according to standard microbiology techniques, and the Kirby–Bauer disk diffusion method was used to assess antimicrobial susceptibility of isolates to a panel of 12 antimicrobials. Susceptibility to methicillin was determined based on the sensitivity of isolates to cefoxitin, and resistant isolates were investigated for the presence of mecA and mecC genes using PCR. Staphylococcus aureus was isolated from 43 (24.6%) of milk, 7 (17.5%) of yogurt, and 2 (5%) of cottage cheese. A significantly higher rate of contamination with S. aureus was recorded among milk samples compared to yogurt and cottage cheese ( p = 0.019 ). Out of 52 S. aureus isolates investigated for susceptibility to 12 antimicrobials, 49 (94.2%) of the isolates were resistant to ampicillin and 42 (80.8%) to amoxicillin+clavulanic acid. Twenty (38.5%) of the isolates were methicillin-resistant S. aureus (MRSA) based on susceptibility to cefoxitin. However, only one of these isolates (5%) was positive for mecA gene, and none of them were positive for the mecC gene. There was no significant difference ( p > 0.05 ) in the rate of occurrence of MRSA among isolates from different sources. In conclusion, this study demonstrated a significant level of contamination of milk and dairy products with S. aureus and most isolates were multidrug resistant. The occurrence of MRSA in raw milk and dairy products signifies a serious public health threat as the practice of consuming raw dairy products in the study area is widespread. The lack of agreement between phenotypic and genotypic detection of MRSA suggests the need for further study to identify the genetic basis for the observed resistance phenotype.

Background: Worldwide Tuberculosis (TB) is the ninth leading cause of death from a single infectious agent, positioning on top of Human Immuno Deficiency Virus (HIV) and it is still an eminently serious public health problem. In developing countries, Ziehl-Neelsen (ZN)-stained sputum smear microscopy is the most widely used diagnostic method in diagnosing Pulmonary Tuberculosis (PTB). This study was aimed to compare the diagnostic performances of ZN-method with Xpert MTB/RIF assay for the diagnosis of PTB in Addis Ababa, Ethiopia. Methods: Facility-based cross-sectional study design was conducted from September 2016 to June 2017 on a total of 244 sputum samples collected from presumptive TB patients. The L-J sputum culture was used as a gold standard to compare the diagnostic performances of Xpert MTB/RIF assay and ZN-methods. Kappa values were analyzed by using statistical package for Social Science (SPSS) version 20 software at 95% Confidence Interval (CI). The Sensitivity, Specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of ZN-stained sputum smear microscopy and Xpert MTB/RIF assay were calculated against the gold standard. Results: The Sensitivity, Specificity, PPV and NPV of ZN-stained sputum smear microscopy were 68.38%, 95.28%, 93.02% and 76.58% respectively, while for Xpert MTB/ RIF assay were 88.89%, 81.89%, 81.89% and 88.89% respectively. The results of the two diagnostic approaches were concordant with the gold standard with a kappa value of ZN 0.650 and 0.743 for Xpert MTB/RIF assay. Conclusion: This study concludes that the sensitivity of Xpert MTB/RIF assay was better than ZN-stained direct sputum smear microscopy for the diagnosis of pulmonary tuberculosis.

Texto completo da fonteResumo:
Background Neglected Tropical Diseases (NTDs) are a group of several communicable and non-communicable diseases prevalent in tropical and subtropical areas. The co-endemicity of these diseases, the similarity of their clinical signs, and the need to maximize limited financial and human resources suggest the importance of adoptingan integratedapproach to their prevention and treatment. Aims This study describes the development of a comprehensive package of physical, mental health and psychosocial care for people with lower-limb lymphoedema caused bypodoconiosis, lymphatic filariasis (LF)or leprosy as part of the EnDPoINT program in Ethiopia. Method The care package was developed using a mixed-methods approach, consisting of a literature review, situational analysis, Theory of Change (ToC) workshops, qualitative research, and additional workshops to fine-tune the draft care package. The care package was developed between March 2018 and January 2020 in Addis Ababa and the implementation research site, Awi zone in the North-West of Ethiopia. Results The holistic care package includes components implemented at three levels of the health care system:health organization, facility, and community. Sections of the care package are directed at strengthening capacity building, program management, community engagement, awareness-raising, stigma-reduction, morbidity management, disability prevention, follow-up visits, referral linkage, community-based rehabilitation, and monitoring and evaluation. Conclusions The study developed a holistic integrated care package for lower limb disorder and co-morbid mental health problems caused by podoconiosis, LF or leprosy. The approach has the potential to significantly reduce lower limb disorder-associated morbidity, disability, and psychosocial problems. It also standardizes a scalable approach appropriate for the Ethiopian setting and, most likely, other countries where these NTDs are present.

Background. Lipodystrophy is one of the clinical complications of insulin injection that affects insulin absorption and leads to poor glycemic control. Objective. To assess insulin-induced lipodystrophy and glycemic control. Methods. A cross sectional study was done on 176 diabetic children and adolescents who inject insulin for a minimum of one year. First, anthropometric and clinical characteristics of the patients were recorded in questionnaire, and then observation and palpation techniques were used in assessing lipodystrophy. Result. Out of the total 176 participants, 103 (58.5%) had insulin-induced lipodystrophy, of them 100 (97.1%) had lipohypertrophy and 3 (2.9%) had lipoatrophy. Being younger, failure to rotate the injection site every week and multiple reuse of insulin syringe had significant influence in development of insulin-induced lipohypertrophy. Lipohypertrophy in turn was associated with the use of higher dose of insulin and nonoptimal glycemic control. Conclusion. Findings of this study revealed that in spite of using recombinant human insulin, the magnitude of the lipohypertrophy still remained high. Therefore, a routine workup of insulin-injecting patients for such complication is necessary, especially in the individuals who have a nonoptimal glycemic control.

Introduction: The COVID-19 pandemic has imposed an extraordinary challenge to the health and socio-economic facet of nations globally. Health facilities have encountered tremendous challenges to contain service delivery at all levels. This study aims to assess the trend of health service utilization and challenges faced during the COVID-19 pandemic at primary units in Addis Ababa, Ethiopia. Method: A multi-facility-based cross-sectional study was conducted in Addis Ababa between 1 and 30 of August 2020. A mixed-methods design was employed, and both quantitative and qualitative data were collected at 5 health centers. Facilities were selected randomly from 5 sub-cities while interviewees were recruited purposively. A structured questionnaire was used to collect quantitative data from the HMIS units of each facility. Qualitative data was collected using a semi-structured key-informant interview guide. Quantitative data were analyzed using Microsoft Excel, and a 10-month time-series trend was generated. For the qualitative data, qualitative data analysis (QDA-minor) software was used. Results: Time-series comparison of the pre-COVID-19 era loads with the COVID-19 period showed that there was an extensive disparity in the service delivery capacity of the health facilities. A huge drop in inpatient flow of some units such as PICT, VCT, FP services, and most sub-units of the OPDs has been recorded following the COVID-19 outbreak. The key-informant interview also revealed that such challenges, as fear of infection and stigma, poor infrastructure, challenges related to human resources, and challenges related to the supply of prevention and treatment inputs were prominently encountered at the health centers. Conclusion: The COVID-19 wave has negatively impacted many service delivery points in the study settings. The presence of weak infrastructure, lack of PPEs, fear of the infection and stigma, and staff workload have been mentioned as the predominant challenges faced during the outbreak. Health authorities should arrange multifaceted supports to ensure uninterrupted service delivery at primary healthcare units.

Background. Human resources for health-care delivery are essential for attaining global health and development goals. Especially in developing countries, health extension workers are frontline health personnel who can play a key role in preventing and controlling HIV/AIDS. This study aimed to evaluate the performance of health extension workers in HIV-1/2 screening tests. Methodology. A comparative cross-sectional study was carried out to evaluate the performance of health extension workers in HIV-1/2 screening tests. Study participants had performed HIV screening tests on the prepared sample panels. Finally, the percentage of accuracy, error rate, sensitivity, specificity, predictive values, and measure of agreement (kappa) were calculated using SPSS version 26. Result. Totally, 1600 HIV screening tests were performed, and of these, 684 and 235 tests were done by HEWs (n = 15) and laboratory personnel (n = 5), respectively, with three discordant results by HEWs from a single sample panel which was weak reactive for HIV antibody test. The sensitivity, specificity, PPV, and NPV of HIV screening tests by HEWs were 97.4%, 100%, 100%, and 97.22%, respectively, and 100% for all parameters when it is tested by laboratory professionals. The measure of kappa agreement was 0.971 (95% CI, 0.932–1) for HEWs and 1 for laboratory personnel compared with the reference result. Conclusion. Based on this evidence, we conclude that the potential contribution of HEWs can be invaluable in the expansion of HIV screening tests nationwide to compensate the shortage of laboratory personnel.

Background. Standard precautions are infection control techniques against pathogenic microorganisms that are present in human blood and can cause disease in humans. Objective. This study aims to assess knowledge and practice of standard precautions against blood borne pathogens among doctors and nurses in adult emergency room, Addis Ababa, Ethiopia. Methods. Institutional based cross sectional study was conducted from February to March 2018. A total of 128 study participants selected from four public hospitals were enrolled in this study. Data were collected using standardized pretested questionnaire and thencoded, entered, checked for completeness, and analyzed using SPSS version-23 statisticalsoftware. Chi-square test was used to measure the association between variables. P values <0.05 were taken as statistically significant. Result. The mean knowledge score of standard precaution measures was 10.3 out of 14 knowledge items. Out of 32 doctors, 93.8% (n=30) have good knowledge and out of 91 nurses, 86.8% (n=79) have good knowledge. The mean practice level of the study subjects was 8.5 out of 12 practice items. Majority (73.6%) of nurses have good practice level than doctors (21.8%). Knowledge level was significantly associated with the presence of infection control officer, infection control guideline, and washing hands before touching patients. Profession, training, and the presence of infection control guideline in emergency room were significantly associated with practice level of respondents (P<0.05). Conclusion. Both nurses and doctors have good knowledge of standard precaution measures. However, nurses have better practice level than doctors. Orientation during employment and continuous training programs should be provided for the newly employed health workers. In addition sustainable supply systems should be available in each hospital management.

Rabies, a viral disease caused by lyssa virus of family Rhabdoviridae, is a fatal zoonotic disease with worldwide occurrence and endemic in developing countries of Africa and Asia. Rabies generally affects all warm-blooded animals, but it is primarily a disease of dogs in Ethiopia because access to suspected domestic canids and pets are not controlled indoor or by immunization. The major means of transmission of the disease is through any types of bite, scratch, or other situation in which saliva, cerebral, spinal fluid, tear, or nervous tissues from suspected or known rabid animal or person enters an open wound, is transplanted into, or comes in contact with mucus membrane of another animals or person. One of retrospective study of rabies in Addis Ababa from 1990 – 2000 indicated that an average of 2,200 people per year received post – exposure antirabies treatment while 95% of the reported fatal human rabies case was due to dog bites. The widespread use of traditional medicine among urban and rural population of Ethiopia could be attributed to cultural acceptability, physical accessibility and economic affordability. Individuals who are exposed to the rabies virus often see traditional healers for the diagnosis and treatments of the disease. Once the virus entered into body of exposed individuals through wound (abrasion) or direct contact with mucosal surface, then there, it replicates in the site of deposit (bitten site), where local viral proliferation occurs, and get access (viral attachment) to motor endplates. The clinical sign of the disease is nonspecific and difficult to differentiate without laboratory test, but some of signs such as pupil dilation in some case, paralysis (last stage) and hydrophobia are some characteristic signs. The control of access to domestic canid to other suspected animals is not only prevention method but also is treatment measures. Mass vaccination of dogs and removal of stray canids are the best measure of control. In general, this study provides an overview of the current status of Rabies in livestock and human in Ethiopia.

Introduction. Breastfeeding is the ideal food source for all newborns globally. However, in the era of Human Immune Deficiency Virus (HIV) infection, feeding practice is a challenge due to mother-to-child HIV transmission. Therefore, this systematic review and meta-analysis aimed to estimate the national prevalence of exclusive breastfeeding and mixed feeding practices among HIV positive mothers and its association with counseling and HIV disclosure status to the spouse in Ethiopia. Methods. We searched all available articles from the electronic databases including PubMed, EMBASE, Google Scholar, and the Web of Science. Moreover, reference lists of the included studies and the Ethiopian institutional research repositories were used. Searching of articles was limited to the studies conducted in Ethiopia and published in English language. We have included observational studies including cohort, cross-sectional, and case-control studies. The weighted inverse variance random effects model was used. The overall variations between studies were checked through heterogeneity test (I2). Subgroup analysis by region was conducted. To assess the quality of the study, the Joanna Briggs Institute (JBI) quality appraisal criteria were employed. Publication bias was checked with the funnel plot and Egger’s regression test. Result. A total of 18 studies with 4,844 participants were included in this study. The national pooled prevalence of exclusive breastfeeding and mixed feeding practices among HIV positive mothers were 63.43% (95% CI: 48.19, 78.68) and 23.11% (95% CI: 10.10, 36.13), respectively. In the subgroup analysis, the highest prevalence of exclusive breastfeeding practice was observed in Tigray (90.12%) and the lowest in Addis Ababa (41.92%). Counseling on feeding option with an odds ratio of 4.32 (95% CI: 2.75, 6.77) and HIV disclosure status to the spouse with an odds ratio of 6.05 (95% CI: 3.03, 12.06) were significantly associated with exclusive breast feedings practices. Conclusion. Most mothers report exclusive breastfeeding, but there are still almost a quarter of mothers who mix feed. Counseling on feeding options and HIV disclosure status to the spouse should be improved.

Background. Human Immune Deficiency Virus (HIV/AIDS) continues to be an underrecognized risk for suicidal ideation, suicidal attempt, and completion of suicide. Suicidal ideation and attempt in HIV/AIDS is not only a predictor of future attempted suicide and completed suicide.Methods. An institution based cross-sectional study was conducted among HIV-positive patients attending HIV care at Zewditu Memorial Hospital. Systematic random sampling technique was used to recruit 423 participants from April to May 2014. Composite International Diagnostic Interview was used to collect data. Multivariable logistic regression was computed to assess factors associated with suicidal ideation and attempt.Result. Suicidal ideation and suicidal attempt were found to be 22.5% and 13.9%, respectively. WHO clinical stage of HIV, not being on HAART, depression, family history of suicidal attempt, and perceived stigma were associated with suicidal ideation. WHO clinical stage, being female, not being on HAART, use of substance, and depression were associated with suicidal attempt.Conclusion. Early diagnosis and treatment of opportunistic infections, depression, and early initiation of ART need to be encouraged in HIV-positive adults. Furthermore, counseling on substance use and its consequences and early identification of HIV-positive people with family history of suicidal ideation have to be considered.
