Patients-to-healthcare workers HIV transmission risk from sharp injuries, Southern Ethiopia
Background: Accidental needlestick injury rate among healthcare workers in Hawassa is extremely high. Epidemiological findings proved the infectious potential of this injury contaminated with a Human  Immunodeficiency Virus (HIV)-infected patient’s blood.Objective: This study aimed at estimating the risk of HIV transmission from patients to healthcare workers in Hawassa City, Ethiopia.Method: A probabilistic risk model was employed. Scenario-based assumptions were made for the values of parameters following areview of published reports between 2007 and 2010.Parameters: HIV prevalence, needlestick injury rate, exposure rate, sero-conversion rate, risk of HIV transmission and cumulative risk of HIV transmission.Finding: Generally, healthcare workers in Hawassa are considered to be at a relatively low (0.0035%) occupational risk of contracting HIV – less than 4 in 100,000 of healthcare workers in the town (1 in 28,751 workers a year). The 30 years’ maximum cumulative risk estimate is approximately five healthcare workers per 1000 workers in the study area. Still, this small number should be considered a serious matter requiring post-exposure prophylaxis following exposure to unsafe medical practice leading to HIV infection
Effects of Gibberellic acid and 2,4-Dichlorophenoxy Acetic Acid Spray on Vegetative Growth, Fruit Anatomy and Seed Setting of Tomato (Lycopersicon esculentum Mill.)
The experiment was conducted at Melkassa Agricultural Research Center, Ethiopia with the objective to evaluate the effects of different concentrations and combinations of 2,4-dichlorophenoxyacetic acid (2,4-D) and gibberellic acid (GA3) spray on vegetative and reproductive growth components of tomato. The experiment consists of two tomato varieties, one processing (Roma VF) and one fresh market (Fetan), three levels of 2,4-D (0, 5 and 10 ppm) and four levels of GA3 (0, 10, 15 and 20 ppm)arranged in 2x3x4 factorial combinations, in Randomized Completed Block design with three replications. Data were collected on qualitative parameters (vegetative, reproductive growth and external fruit color) through visual observation, and quantitative parameters (seed number per fruit, seed weight per fruit, fruit shape index and average fruit weight). Qualitative data were analyzed using analysis of variance (ANOVA) by SAS (2002) software and mean separation was carried out by DMRT at 5% probability level. The result indicated that tomato plant treated with 2,4-D intended to have increased stem thickness, decreased leaf size induced epinastic and flower bud abscission in both cultivars while GA3 treatment has no retarded growth and flower bud abscission. Application of 2,4-D has responsible in the development of seedless parthenocarpic fruit with increased size but with unfilled cavities especially at higher concentration. On the other hand, GA3 at lower concentration results in normal fruit and seed development but as its concentration increases it results in the development of more proportion of smaller fruits per plant and formation of blotchy ripening on the fruit. Combined application of the two PGRs at lowers concentrations seems to result in the intermediate effects of both PGRs in single application. In general, concentration of the PGRs used and genetic background of the variety determine the response of tomato growth, fruit setting, seed formation and final marketable fruit size
Assessment of Improved Tef (Eragrostis tef L.) Varieties for Yield and Yield Related Traits at Nono Benja and Cheliya Districts, Oromia, Ethiopia
Tef (Eragrostis tef) is one of the most important and strategic cereal crop grown to drought prone areas of Ethiopia. Genetic variability, genotypic correlations and yield components are prerequisite for selection of crop breeding, cultivation of improved varieties that provides optimum seed yield is one of the major constraints of the crop. The present study was aimed to investigate the adaptive and best performing tef varieties based on their yield and related traits under rain fed conditions at Nono Benja and Celia districts in Ethiopia. The experiment was conducted by using split plot design with three replications, sixteen improved varieties and one local landrace. The combined analysis of variance revealed that varieties were significantly different for studied characters except panicle length, total tiller number and spikelet length. The mean yields of nine improved varieties (Dukem, Asgori, Tesfa, Negus, Quncho, Kora, Koye, Boset and key tena) were relatively higher than the local check comparing with mean values of grain yield ranged from Welkomi (372.08 kg/ ha) to Dukem (1315.41 kg/ ha).Grain yields were studied high in four varieties across two locations were (Dukem (1315.4 kg/ ha), asgori (1279.6 kg/ ha), Tesfa (1206.02 kg/ ha), Negus (1072.61 kg/ ha) with 72.8%, 68.2%, 58.5 %, and 41% over local check. The genotypic coefficient variation was observed that from 4.6% to 82.9% for loading index and the phenotypic coefficient variation range from 5.8% to 91.0% for loading index at Cheliya, respectively, the fertilizer application (0, 60/40 P/N kgha-1) showed highly differences among all traits except in GFP, PH and TGW traits. The varieties Gibe, Koye, Boset, Gimbichu, Enat and Kora were observed highly strong association with the environment, similarly Asgori and Gedo varieties were showed highly significant and strong connection with the environment Nono Benja with fertilization. Results reveal that the correlation studies provide a better understanding of yield components during the selection of tef genotypes

Dataset for SERS plasmonic array: Width, spacing, and thin film oxide thickness optimization
Surface-enhanced Raman spectroscopy (SERS) improves the scope and power of Raman spectroscopy by taking advantage of plasmonic nanostructures, which have the potential to enhance Raman signal strength by several orders of magnitude, which can allow for the detection of analyte molecules. The dataset presented provides results of a computational study that used a finite element method (FEM) to model gold nanowires on a silicon dioxide substrate. The survey calculated the surface average of optical surface enhancement due to plasmonic effects across the entire model and studied various geometric parameters regarding the width of the nanowires, spacing between the nanowires, and thickness of the silicon dioxide substrate. From this data, enhancement values were found to have a periodicity due to the thickness of the silicon dioxide. Additionally, strong plasmonic enhancement for smaller distances between nanowires were found, as expected; however, additional surface enhancement at greater gap distances were observed, which were not anticipated, possibly due to resonance with periodic dimensions and the frequency of the light. This data presentation will benefit future SERS studies by probing further into the computational and mathematical material presented previously
Mortality and Disability-adjusted Life-years (DALYs) for common neglected tropical Diseases in Ethiopia, 1990 to 2015: evidence from the Global Burden of Disease Study 2015
Introduction: Neglected tropical diseases (NTDs) are important public health problems in Ethiopia. In 2013, the Federal Ministry of Health (FMOH) has launched a national NTD master plan to eliminate major NTDs of public health importance by 2020. Benchmarking the current status of NTDs in the country is important to monitor and evaluate the progress in the implementation of interventions and their impacts. Therefore, this study aims to assess the trends of mortality and Disability-adjusted Life-Years (DALY) for the priority NTDs over the last 25 years.
Methods: We used the Global Burden of Disease (GBD) 2015 estimates for this study. The GBD 2015 data source for cause of death and DALY estimation included verbal autopsy (VA), Demographic and Health Surveys (DHS), malaria indicator surveys (MICS) and other disease specific surveys, Ministry of Health reports submitted to United Nations (UN) agencies and published scientific articles. Cause of Death Ensemble modeling (CODEm) and/or natural history models were used to estimate malaria and NTDs mortality rates. DALY were estimated as the sum of Years of Life Lost (YLL) due to premature mortality and Years Lived with Disability (YLD).
Results: All NTDs caused an estimated of 6,293 deaths (95% uncertainty interval (UI): 3699 – 10,080) in 1990 and 3,593 deaths (95% UI: 2051 – 6178) in 2015, a 70% reduction over the 25 years. Age-standardised mortality rates due to schistosomiasis, STH and leshmaniasis have declined by 91.3%, 73.5% and 21.6% respectively between 1990 to 2015. The number of DALYs due to all NTDs has declined from 814.4 thousand (95% UI: 548 thousand–1.2 million) in 1990 to 579.5 thousand (95%UI: 309.4 thousand – 1.3 million) in 2015. Age-standardised DALY rates due to all NTDs declined by 30.4%, from 17.6 per 1000(95%UI: 12.5-26.5) in 1990 to 12.2 per 1000(95%UI: 6.5 – 27.4) in 2015. Age-standardised DALY rate for trachoma declined from 92.7 per 100,000(95% UI: 63.2 – 128.4) in 1990 to 41.2 per 100,000(95%UI: 27.4 – 59.2) in 2015, a 55.6% reduction between 1990 and 2015. Age-standardised DALY rates for onchocerciasis, schistosomiasis and lymphiatic filariasis decreased by 66.2%, 29.4% and 12.5% respectively between 1990 and 2015. DALY rate for ascariasis fell by 56.8% over the past 25 years.
Conclusions: Ethiopia has made a remarkable progress in reducing the DALY rates for most of the NTDs over the last 25 years. The rapid scale of interventions and broader system strengthening may have a lasting impact on achieving the 2020 goal of elimination of most of NTDs. Ethiopia should strengthen the coverage of integrated interventions of NTD through proper coordination with other health programs and sectors and community participation to eliminate NTDs by 2020
Client preferences and acceptability for medical abortion and MVA as early pregnancy termination method in Northwest Ethiopia
<p>Abstract</p> <p>Background</p> <p>Increasing access to safe abortion services is the most effective way of preventing the burden of unsafe abortion, which is achieved by increasing safe choices for pregnancy termination. Medical abortion for termination of early abortion is said to safe, effective, and acceptable to women in several countries. In Ethiopia, however, medical methods have, until recently, never been used. For this reason it is important to assess women's preferences and the acceptability of medical abortion and manual vacuum aspiration (MVA) in the early first trimester pregnancy termination and factors affecting acceptability of medical and MVA abortion services.</p> <p>Methods</p> <p>A prospective study was conducted in two hospitals and two clinics from March 2009 to November 2009. The study population consisted of 414 subjects over the age of 18 with intrauterine pregnancies of up to 63 days' estimated gestation. Of these 251 subjects received mifepristone and misoprostol and 159 subjects received MVA. Questionnaires regarding expectations and experiences were administered before the abortion and at the 2-week follow-up visit.</p> <p>Results</p> <p>The study groups were similar with respect to age, marital status, educational status, religion and ethnicity. Their mean age was about 23, majority in both group completed secondary education and about half were married. Place of residence and duration of pregnancy were associated with method choice. Subjects undergoing medical abortions reported significantly greater satisfaction than those undergoing surgical abortions (91.2% vs 82.4%; <it>P </it>< .001). Of those women who had medical abortion, (83.3%) would choose the method again if needed, and (77.4%) of those who had MVA would also choose the method again. Ninety four percent of women who had medical abortion and 86.8% of those who had MVA would recommend the method to their friends.</p> <p>Conclusions</p> <p>Women receiving medical abortion were more satisfied with their method and more likely to choose the same method again than were subjects undergoing surgical abortion. We conclude that medical abortion can be used widely as an alternative method for early pregnancy termination.</p
Health gains and fi nancial risk protection aff orded by public fi nancing of selected interventions in Ethiopia: an extended cost-eff ectiveness analysis
Background The way in which a government chooses to fi nance a health intervention can aff ect the uptake of health
interventions and consequently the extent of health gains. In addition to health gains, some policies such as public
fi nance can insure against catastrophic health expenditures. We aimed to evaluate the health and fi nancial risk
protection benefi ts of selected interventions that could be publicly fi nanced by the government of Ethiopia.
Methods We used extended cost-eff ectiveness analysis to assess the health gains (deaths averted) and fi nancial risk
protection aff orded (cases of poverty averted) by a bundle of nine (among many other) interventions that the
Government of Ethiopia aims to make universally available. These nine interventions were measles vaccination,
rotavirus vaccination, pneumococcal conjugate vaccination, diarrhoea treatment, malaria treatment, pneumonia
treatment, caesarean section surgery, hypertension treatment, and tuberculosis treatment.
Findings Our analysis shows that, per dollar spent by the Ethiopian Government, the interventions that avert the most
deaths are measles vaccination (367 deaths averted per 100 000 spent), and caesarean section surgery (141 deaths averted per 100 000 spent), tuberculosis
treatment (96 cases averted per 100 000 spent).
Interpretation Our approach incorporates fi nancial risk protection into the economic evaluation of health interventions
and therefore provides information about the effi ciency of attainment of both major objectives of a health system:
improved health and fi nancial risk protection. One intervention might rank higher on one or both metrics than
another, which shows how intervention choice—the selection of a pathway to universal health coverage—might
involve weighing up of sometimes competing objectives. This understanding can help policy makers to select
interventions to target specifi c policy goals (ie, improved health or fi nancial risk protection). It is especially relevant
for the design and sequencing of universal health coverage to meet the needs of poor populations
