Although a large number of single nucleotide polymorphisms (SNPs) have been identified from the bovine genome-sequencing project, few of these have been validated at large in Bos indicus breeds. We have genotyped 192 animals, representing 5 cattle populations of Ethiopia, with the Illumina Bovine 8K SNP BeadChip. These include 1 Sanga (Danakil), 3 zebu (Borana, Arsi and Ambo), and 1 zebu x Sanga intermediate (Horro) breeds. The Hanwoo (Bos taurus) was included for comparison purposes. Analysis of 7,045 SNP markers revealed that the mean minor allele frequency (MAF) was 0.23, 0.22, 0.21, 0.21, 0.23, and 0.29 for Ambo, Arsi, Borana, Danakil, Horro, and Hanwoo, respectively. Significant differences of MAF were observed between the indigenous Ethiopian cattle populations and Hanwoo breed (p < 0.001). Across the Ethiopian cattle populations, a common variant MAF (> or =0.10 and < or =0.5) accounted for an overall estimated 73.79% of the 7,045 SNPs. The Hanwoo displayed a higher proportion of common variant SNPs (90%). Investigation within Ethiopian cattle populations showed that on average, 16.64% of the markers were monomorphic, but in the Hanwoo breed, only 6% of the markers were monomorphic. Across the sampled Ethiopian cattle populations, the mean observed and expected heterozygosities were 0.314 and 0.313, respectively. The level of SNP variation identified in this particular study highlights that these markers can be potentially used for genetic studies in African cattle breeds.

This study aimed to compare the perceptions of pharmacy clerkship students and clinical preceptors of preceptors' teaching behaviors at Gondar University. A cross-sectional study was conducted among pharmacy clerkship students and preceptors during June 2014 and December 2015. A 52-item structured questionnaire was self-administered to 126 students and 23 preceptors. The responses are presented using descriptive statistics. The Mann-Whitney U test was applied to test the significance of differences between students and preceptors. The response rate was 89.4% for students and 95.6% for preceptors. Statistically significant differences were observed in the responses regarding two of the five communication skills that were examined, six of the 26 clinical skills, and five of the 21 parameters involving feedback. The mean scores of preceptors (2.6/3) and students (1.9/3) regarding instructors' ability to answer questions were found to be significantly different (P= 0.01). Students and preceptors gave mean scores of 1.9 and 2.8, respectively, to a question regarding preceptors' application of appropriate up-to-date knowledge to individual patients (P= 0.00). Significant differences were also noted between students and instructors regarding the degree to which preceptors encouraged students to evaluate their own performance (P= 0.01). Discrepancies were noted between students and preceptors regarding preceptors' teaching behaviors. Preceptors rated their teaching behaviors more highly than students did. Short-term training is warranted for preceptors to improve some aspects of their teaching skills.

BACKGROUND: Less attention is given to cancer treatment and control in Ethiopia. METHODS: To investigate the challenges and opportunities facing cancer treatment services in Ethiopia. A purposive sampling technique was applied to recruit the study subjects from Black Lion Specialized Hospital Oncology Department. A semi-structured interview guide was used to investigate challenges and opportunities in oncology service in Ethiopia. Data was transcribed and coded by two independent coders and analyzed thematically in reference to the objectives. RESULTS: Fifteen professionals from four different disciplines were interviewed on opportunities and challenges facing cancer treatment in Ethiopia. Out of these respondents 3 were senior clinical oncologists while 4 individuals were senior oncology residents. The rest were 2 medical Physicists, 2 radiotherapy technologists and 4 oncology nurses. Majority (80%) of the respondents were males. We demonstrate that the challenges of cancer treatment service in Ethiopia emanate from the patients themselves, the administrating body, the professionals, and the technology limitations. In general, the result of this study was grouped under the following five themes: Customer-related challenges, provider-related challenges, facility-related challenges, technology-related challenges and the opportunities. CONCLUSIONS: Several assignments are waiting for the policy makers, the professionals, the communities and other concerned bodies to combat the alarmingly growing burden of cancer in Ethiopia. Escalating the awareness of the general population about cancer, expanding well-developed diagnostic and treatment centers, and producing well-trained competent oncology professionals are the forefront challenges in combating cancer in Ethiopia.

OBJECTIVES: To assess the prevalence and determinants of work-related injuries among small and medium scale industrial workers in Bahir Dar town, northwest Ethiopia. METHOD: Cross sectional comparative study design was used. Purposive sampling method was used to choose the specific Kebele 14 of the study area, for its relatively high number of industries. The study units were stratified into small and medium scale industries. All workers who were available at the time of interview were included in the study. A pre-tested questionnaire was used to collect data. Data was analyzed using SPSS for windows 16.0. RESULT: A total of 328 and 655 workers from small and medium-scale industries respectively participated in the study. Seven hundred sixty nine (78.2%) were males. Three hundred thirty six workers (34.2%) reported that they had experienced work-related injuries. Sex, monthly salary, age, work experience and use of personal protective equipment were found to be different in the small and medium industries (P < 0.05). CONCLUSION: There was a high prevalence of work related injuries. Sociodemographic, socioeconomic, personal work behavior and the working environment have contributed for the injuries. Work-related injuries are assumed to be preventable with the provision of occupational health programs in workplaces. Thus it is recommended that the owners of industries need to focus on training and installing safer work environment and Further studies with large-scale coverage and prospective study designs are warranted.

OBJECTIVES: Associations between khat (Catha edulis) chewing and different adverse oral-dental health conditions have been reported, yet evidence is still lacking. This study was designed to investigate the association between long-term regular khat chewing and self-reported oral symptoms. METHODS: A cross-sectional study was conducted on a sample of 1,255 university students in southern Ethiopia. Data on khat chewing status, a range of oral symptoms and other pertinent variables were collected using self-administered questionnaires. The association between long-term regular khat chewing and oral symptom count was investigated using negative binomial regression. RESULTS: The mean oral symptom count among long-term regular khat chewers was 1.75 (standard deviation [SD], 2.18; standard error [SE], 0.31), whereas that among those who were not long-term regular khat chewers was 1.18 (SD, 1.68; SE, 0.10). After adjustment for other variables, long-term regular khat chewers had approximately 50% more oral symptoms than those who were not long-term chewers did (adjusted count ratio, 1.53; 95% confidence interval, 1.12 to 2.10). CONCLUSIONS: Long-term khat chewing negatively affects the oral health of young university students.

OBJECTIVES: The prevalence of childhood obesity has more than doubled since it was formally recognized as a global epidemic in 1997. With the increasingly dwindling space for private schools in Ethiopia, unresolved concerns exist among the public regarding the possible effect of limited play areas in schools on overweight/obesity. This study intended to determine and compare the levels of overweight/obesity among adolescents in private schools with and without adequate play area in Addis Ababa, Ethiopia. METHODS: A school-based comparative cross-sectional study was conducted among 1,276 adolescents. Twenty private schools were grouped into 2 groups based on the size of the play area. Data were collected using a pre-tested questionnaire and anthropometric measurements and analyzed using descriptive statistical tests and logistic regression. RESULTS: The magnitude of overweight/obesity was significantly higher in schools with inadequate play area (19.4%; 95% confidence interval [CI], 16.4 to 22.7) than in schools with adequate play area (14.6%; 95% CI, 11.9 to17.5). Inadequacy of the play area was also positively associated with overweight/obesity in the multiple logistic regression analysis (odds ratio [OR], 1.62; 95% CI, 1.05 to 2.51). Using private car transportation to and from school (OR, 2.27; 95% CI, 1.13 to 4.57), father’s educational status (secondary school and above: OR, 2.54; 95% CI, 1.14 to 5.62), and middle wealth quintile (OR, 2.54; 95% CI, 1.50 to 4.33) were other factors significantly associated with overweight/obesity. CONCLUSIONS: Inadequate play area in schools was an important contributor to overweight/obesity. Sedentary behavior was also significantly associated with overweight/obesity.

OBJECTIVES: The Aedes mosquito is a vector for transmitting many arboviruses. Knowledge of the breeding habitat of this vector is vital for implementing appropriate interventions. Thus, this study was conducted to determine the breeding habitats and presence of Aedes mosquito species in the study areas. METHODS: A house-to-house cross-sectional survey of Aedes mosquito breeding habitats was carried out in Metema and Humera, Ethiopia, in August 2017. All available water-holding containers present in and around houses were inspected for the presence of immature stages of Aedes mosquitoes, and they were collected and reared to the adult stage for species identification. In the larval survey, the house index, container index, and Breteau index were computed as risk indices. RESULTS: Of the 384 houses surveyed for the presence of Aedes mosquito larval breeding, 98 were found to be positive for larvae. During the survey, a total of 566 containers were inspected, of which 186 were found to be infested with Aedes mosquito larvae, with a container index of 32.9, a house index of 25.5, and a Breteau index of 48.4. The most common Aedes mosquito breeding habitats were discarded tires (57.5%), followed by mud pots (30.0%). Of the 1,077 larvae and pupae collected and reared, Aedes aegypti (49.3%), Ae. vittatus (6.5%), and Culex species (44.2%) were identified. CONCLUSIONS: Discarded tires were the most preferred breeding habitats for Aedes mosquitoes. Moreover, Ae. aegypti, the main vector of dengue and other arboviruses, was identified for the first time in this region, suggesting a high potential for arbovirus transmission in the study areas.

BACKGROUND: Improved water sources are not equally available in all geographical regions. Populations dependent on unsafe water sources are recommended to treat their water at point-of-use using adequate methods to reduce associated health problems. In Ethiopia, the spatial distribution of households using unimproved water sources have been incomplete or ignored in most of the studies. Moreover, evidence on the point-of-use water treatment practice of households dependent on such water sources is scarce. Therefore, the current study is intended to analyze the spatial distribution of unimproved water sources by wealth quintiles at country level and point-of-use treatment (POU) practices using nationally representative data. METHOD: The data of 2016 Ethiopian Demographic and Health Survey (EDHS) conducted on 16650 households from 643 clusters were used for the analysis. For spatial analysis, the raw and spatially smoothed coverage data was joined to the geographic coordinates based on EDHS cluster identification code. Global spatial autocorrelation was performed to analyze whether the pattern of unimproved water coverage is clustered, dispersed, or random across the study areas. Once a positive global autocorrelation was confirmed, a local spatial autocorrelation analysis was applied to detect local clusters. The POU water treatment is analyzed based on reported use of either boiling, chlorine (bleach), filtration, or solar disinfection (SODIS). RESULTS: There were 5005 households using unimproved water sources for drinking purposes. Spatial variation of unimproved water coverage was observed with high coverage observed at Amhara, Afar, Southern Nations Nationalities and People and Somalia regions. Disparity in unimproved water coverage between wealth quintiles was also observed. The reported point-of-use water treatment practice among these households is only 6.24%. The odds of POU water treatment among household heads with higher education status is 2.5 times higher (95% CI = 1.43-4.36) compared to those who did not attend education. CONCLUSION An apparent clustering trend with high unimproved water coverage was observed between regions and among wealth quintiles hence indicates priority areas for future resource allocation and the need for regional and national policies to address the issue. Promoting households to treat water prior to drinking is essential to reduce health problems.
