A comprehensive study on the cattle production situation owned by refugees and hosting communities in the Gambella region, southwestern Ethiopia

This study was designed to assess the state of cattle production and the contributions that cattle production makes to enhance the livelihoods, food security, and nutrition of refugees and the host community in the Gambella region in southwest Ethiopia. Two hundred fifty-five cattle owners were purposefully chosen for the study, and information was gathered through questionnaires, focus group discussions, and key informant interviews. The average number of animals per household (sd; +0.002 range: 1 to 490) was 32.37. The study observed a total of 8,258 cattle of which 8,146 belonged to the Nuer breed and 112 to the Felata breed. The reason for maintaining cattle varies statistically across the host community, re-settlers, and refugee communities (x2=50.358; p-value =0.000). According to the current study, 92.5% (236/255) of cattle owners used a free-grazing system, and the mean daily milk yield per cow during the dry and rainy seasons, respectively, was 1.35L and 2.09L. All respondents (100%) agree that there exist cattle diseases in the research area, and 79.6% of cattle owners employed traditional medicine to prevent and treat cattle diseases. Some of the potentials for cattle production in the study areas were cultural value, the existence of disease-tolerant breeds, the availability of manpower, and local expertise. Therefore, it is highly advised that a thorough analysis of the various agro-ecologies in the area be necessary to understand the reproductive and productive performance of cattle

A systematic review of unintended pregnancy in cross-cultural settings: Does it have adverse consequences for children?

Introduction: Although there has been a great deal of concern about the consequences of unintended pregnancies on child health, there has been little documented evidence across specific outcomes to inform programs and policies. This paper highlights the association between unintended pregnancy, and its health and developmental consequences to children.Methods: Published and grey evidence available adverse effects of unintended pregnancy on children were extracted electronically using search engines: PubMed, EMBASE and Google Scholar for the period January 1981 through January 2017. The PRISMA checklist was used and qualities of eligible studies were assessed for method validity and result interpretation. Effect-size odds ratioswere calculated from extracted data.Results: Of the 107 studies identified after removal of duplications, 29 studies with a quality score ranging from 3 to 6 (Mean = 5.65; SD±0.65) were included. Pattern of child rearing, development and health were found to differ for children classified to be breads of an unintended pregnancy. However, many of the available studies appear to have methodological limitations such as recall bias and brief period of follow-ups limiting causal inferences and to determine a temporal sequence. The findings were found to be inconsistent across studies.Conclusion: Studies provide evidence relating to adverse health outcomes for children of unintended births. The existing knowledge is limited by weak research methodologies and a paucity of studies addressing subsequent health and developmental effects beyond the early childhood period. There is a need for more multi-wave longitudinal studies to assess child health and developmental trajectories associated with unintended pregnancies. [Ethiop. J.

4d N=1\mathcal{N} = 1/2d Yang-Mills Duality in Holography

We study the supergravity dual of four-dimensional ${\mathcal{N}=1}$ superconformal field theories arising from wrapping M5-branes on a K\"ahler two-cycle inside a Calabi-Yau threefold. We derive an effective three-dimensional theory living on the cobordism between the infrared and ultraviolet Riemann surfaces, describing the renormalization group flows between AdS$_7$ and AdS$_{5}$ as well as between different AdS$_{5}$ fixed points. The realization of this system as an effective theory is convenient to make connections to known theories, and we show that upon imposing (physical) infrared boundary conditions, the effective three-dimensional theory further reduces to two-dimensional $SU(2)$ Yang-Mills theory on the Riemann surface, thus deriving a correspondence between the gravity duals of a class of $\mathcal{N}=1$ superconformal field theories arising from wrapping M5-branes on a Riemann surface and two-dimensional Yang-Mills theory on the same Riemann surface.Comment: 18 pages, 2 figure

Assessment of knowledge, attitude and risk behaviors towards HIV/AIDS and other sexual transmitted infection among preparatory students of Gondar town, north west Ethiopia

<p>Abstract</p> <p>Background</p> <p>The first case of HIV in Ethiopia was reported in 1984. Since then, HIV/AIDS has become a major public health concern in the country, leading the Government of Ethiopia to declare a public health emergency in 2002. Although the epidemic is currently stable, HIV/AIDS remains a major development challenge for Ethiopia. The spread of HIV in any community is in part determined by the knowledge of attitude towards sexuality of its members and by their actual sexual practices. The aim of the study was to assess students' knowledge, attitudes and practices regarding HIV/AIDS and STDs in Gondar, North West Ethiopia.</p> <p>Methods</p> <p>A cross sectional study was conducted between February 1 to March 1, 2009 in preparatory high school students. Pre-tested questioner was used to generate the data and analysis was made by SPSS version 15. Chi -square value was calculated and p-value < 0.05 was considered statistically significant.</p> <p>Results</p> <p>All the students had heard about AIDS before the interview. Knowledge on some aspect of the disease was quite low in the study group. Only half of the students knew that at present, AIDs is incurable and that HIV infection can be acquired through sexual contact with a 'familiar' person. Knowledge about STI was also quite low, 39% knew that pus in the urine is a symptom of STI and 45.4% knew that acquisition of other STIs is increases the chance of HIV transmission following unsafe sex with known cases. 25% of the study group had previous sexual intercourse and exposed at least one risk behavior. About 34% of the respondents had negative attitude towards AIDS and STDs.</p> <p>Conclusion</p> <p>Awareness about STDs and methods of prevention of HIV and STDs was low. More risk behavior was observed in male and those with alcohol and drugs of abuse.</p

Height deficit in early adulthood following substantiated childhood maltreatment: a birth cohort study

Early life stress including childhood maltreatment has been associated with reduced head circumference and/or brain size, cognitive, and academic deficits in children and adolescents. However, little is known about the effect of childhood maltreatment on height, especially in early adulthood. This study was designed to examine the association between confirmed cases of multiple or subtypes of childhood maltreatment and stunted growth in young adulthood controlling for perinatal and familial confounding factors. A total of 2661 (48.4% female) young adults from the Mater Hospital-University Study of Pregnancy (MUSP) had data on standardised height-for-age score measurement as part of physical assessment at the 21-year follow-up. Prospectively substantiated cases of childhood maltreatment, 0–14 years of age, were linked to the MUSP dataset. Ethical approval was obtained from the Human Ethics Review Committee of The University of Queensland and the Mater Hospital. Multiple regression analyses were performed to determine the effects of childhood maltreatment on height in young adults. Childhood physical or emotional abuse and neglect were significantly associated with a deficit in height in young adulthood after controlling for perinatal and familial confounders. Multiple incidents of childhood maltreatment also were associated with a deficit in height

Gender-based differences in injecting drug use by young adults who experienced maltreatment in childhood: findings from an Australian birth cohort study

Background Childhood maltreatment has been associated with a range of adverse mental and psychosocial outcomes, but its association with subsequent injecting drug use (IDU) is less clear. This study investigates the associations between specific and multiple forms of substantiated childhood maltreatment and IDU reported at 21 years. Method The Mater-University of Queensland Study of Pregnancy is a prospective birth cohort study. It recruited pregnant women at their first antenatal clinic visit and collected data on their children at 21 years. Data from 3750 participants (1769 males and 1981 females) were analysed using agency substantiated childhood maltreatment from birth to 14 years of age and self-reports of ever IDU at 21 years. We used multivariable logistic regression analyses to control for possible confounders. Results The sample's mean age was 20.6 years. Some 4.1% (n\ua0=\ua072) of males and 4.6% (n\ua0=\ua091) of females had experienced substantiated childhood maltreatment. The prevalence of IDU was 6.6% (n\ua0=\ua0118) and 4.6% (n\ua0=\ua091) for males and females, respectively. In adjusted models, all forms of substantiated childhood maltreatment, with the exception of sexual abuse, were associated with IDU in females (adjusted odds ratios (AORs)\ua0=\ua02.69–3.02) but only emotional abuse (AOR\ua0=\ua02.51) was associated with IDU in males. Multiply occurring forms of childhood maltreatment were also associated with IDU in females (AORs\ua0=\ua02.36–3.41) but not in males. Conclusions Injecting drug use appears to be an adverse outcome of childhood maltreatment particularly in females. Additional research is needed to better understand why females appear to be more affected than males

Global, regional, and country-specific lifetime risks of stroke, 1990 and 2016

BACKGROUND The lifetime risk of stroke has been calculated in a limited number of selected populations. We sought to estimate the lifetime risk of stroke at the regional, country, and global level using data from a comprehensive study of the prevalence of major diseases. METHODS We used the Global Burden of Disease (GBD) Study 2016 estimates of stroke incidence and the competing risks of death from any cause other than stroke to calculate the cumulative lifetime risks of first stroke, ischemic stroke, or hemorrhagic stroke among adults 25 years of age or older. Estimates of the lifetime risks in the years 1990 and 2016 were compared. Countries were categorized into quintiles of the sociodemographic index (SDI) used in the GBD Study, and the risks were compared across quintiles. Comparisons were made with the use of point estimates and uncertainty intervals representing the 2.5th and 97.5th percentiles around the estimate. RESULTS The estimated global lifetime risk of stroke from the age of 25 years onward was 24.9% (95% uncertainty interval, 23.5 to 26.2); the risk among men was 24.7% (95% uncertainty interval, 23.3 to 26.0), and the risk among women was 25.1% (95% uncertainty interval, 23.7 to 26.5). The risk of ischemic stroke was 18.3%, and the risk of hemorrhagic stroke was 8.2%. In high-SDI, high-middle-SDI, and low- SDI countries, the estimated lifetime risk of stroke was 23.5%, 31.1% (highest risk), and 13.2% (lowest risk), respectively; the 95% uncertainty intervals did not overlap between these categories. The highest estimated lifetime risks of stroke according to GBD region were in East Asia (38.8%), Central Europe (31.7%), and Eastern Europe (31.6%), and the lowest risk was in eastern sub-Saharan Africa (11.8%). The mean global lifetime risk of stroke increased from 22.8% in 1990 to 24.9% in 2016, a relative increase of 8.9% (95% uncertainty interval, 6.2 to 11.5); the competing risk of death from any cause other than stroke was considered in this calculation. CONCLUSIONS In 2016, the global lifetime risk of stroke from the age of 25 years onward was approximately 25% among both men and women. There was geographic variation in the lifetime risk of stroke, with the highest risks in East Asia, Central Europe, and Eastern Europe

Incidence, prevalence and mortality rates of malaria in Ethiopia from 1990 to 2015: analysis of the global burden of diseases 2015

Background: In Ethiopia there is no complete registration system to measure disease burden and risk factors accurately. In this study, the 2015 Global Burden of Diseases, Injuries and Risk factors (GBD) data were used to analyse the incidence, prevalence and mortality rates of malaria in Ethiopia over the last 25 years. Methods: GBD 2015 used verbal autopsy (VA) surveys, reports, and published scientific articles to estimate the burden of malaria in Ethiopia. Age and gender-specific causes of death for malaria were estimated using Cause of Death Ensemble Modelling (CODEm). Results: The number of new cases of malaria declined from 2.8 million (95% uncertainty interval (UI): 1.4-4.5million) in 1990 to 621,345 (95% UI: 462,230-797,442) in 2015. Malaria caused an estimated 30,323.9 deaths (95% UI: 11,533.3-61,215.3) in 1990 and 1,561.7 deaths (95% UI: 752.8-2,660.5) in 2015, a 94.8% reduction over the 25 years. Age-standardized mortality rate of malaria has declined by 96.5% between 1990 and 2015 with an annual rate of change (ARC) of 13.4%. Age-standardized malaria incidence rate among all ages and gender declined by 88.7% between 1990 and 2015. The number of disability-adjusted life years lost (DALY) due to malaria decreased from 2.2 million (95% UI: 0.76-4.7 million) in 1990 to 0.18 million (95% UI: 0.12-0.26 million) in 2015, with a total reduction 91.7%. Similarly, age-standardized DALY rate declined by 94.8% during the same period. Conclusions: Ethiopia has achieved a 50% reduction target of malaria of the Millennium Development Goals (MDGs). The country should strengthen its malaria control and treatment strategies to achieve the Sustainable Development Goals (SDG)
