Effect of Musculoskeletal Disorders on the Reproductive Performance of Holstein Zebu Cross Dairy Cows

Two farms with a relatively better record keeping practice were selected to study the effect of musculoskeletal disorder (MSD) on reproductive and lactation performance. The dairy cows found in these farms were categorized into positive or negative to any form of MSD based on their health record and clinical findings. Reproductive performance was measured from CI, CFS, CCI, DALC, NSPC and NSALC. Further, lactation performance was also measured from average daily milk yield, total milk yield and lactation length. Out of the 92 cows, 23.9% were found to be positive for one form of MSD. The mean (±SEM) for CI, CFS, CCI, DALC NSPC and NSALC for the positive cows were 560.9±37.87, 186.2±12.81, 383.3±59.69, 313.6±35.69, 4.30±0.52, and 3.3±0.27, respectively. There was a significant difference (p<0.05) in CI, CFS, CCI NSPC and NSALC between MSD positive and MSD negative cows. The average daily milk yield, total milk yield and lactation length were in the order of 9.7±0.5 L, 3890.7±249.3 L and 413.1±17.54 days, respectively with a significant difference (P<0.05) in milk production between  MSD positive MSD negative cows. Lactation length was unaffected by MSD. This study clearly showed MSD has a direct impact on the reproductive performance dairy cows and significantly influence milk production, which could be the reason for lack of improvement in the urban smallholder dairy industry in Ethiopia.

Prediction of genetic gains for breeding objective traits and designing selection schemes for Washera and Gumuz indigenous sheep

In Ethiopia,there are 32.85 millions of sheep,more than 99 % of which are indigenous.However,the productivity of local sheep under traditional production system is low with high mortality of sheep.There are two ways of improving performance of sheep and goats,namely improving the enviroment of animals and/or improving there genetic potential.The aim of this study was to predict genetic gains of breedingobjective traits and select the best sheep selection scheme for Gumuz andWashera sheep. Body size(six month weight and yearling weight) and litter size were breeding objective traits identified by own flock animal ranking experiment and personal interview. Deterministic approach of ZPLAN computor program is used for modeling input parametres of Gumuz and Washera sheep and simulating breeding plans using gene flow method and selection index procedures. One-tier cooperative sheep breeding scheme were proposed whereby ram exchange between and within villages is the main means of genetic dissimination. Genetic gains predicted for six month weight of Gumuz and Washera sheep were 0.43 and 0.55 kg,respectively. Genetic gains predicted for yearling weight of Gumuz and Washera sheep were 0.55 and 0.60 kg,respectively. Genetic gains predicted for litter  size of Gumuz and Washera sheep were 0.08 and 0.09 lambs,respectively. The lower rate of inbreeding, the higher monetary genetic gain for aggregate genotype,higher return to investmnet and higher profit/ewe/year were quality measures of breeding program considered to prefer scheme 4 for both Gumuz and Washera sheep.Hence,for both Gumuz and Washera sheep populations a sheep selection scheme designed with 15 % selection proportion and one year ram use for breeding was recommended. Special emphasis need to be given to yearling weight with higher predicted genetic response and higher percentage return to investment

Sero-prevalence of Hepatitis B virus surface antigen and associated factors among women of reproductive age in Bench Maji Zone, Southwest Ethiopia: community based cross-sectional study

Background: Hepatitis B virus infection is one of the leading causes of liver diseases which occurs worldwide particularly in developing countries. It is often caused by prenatal transmission from mother to child or household transmission from a close contact during early childhood. It causes different complications like; jaundice, induces premature labor, and prematurity. Objective: The aim of this study was to estimate the sero-prevalence of hepatitis B virus surface antigen and associated factors among women of reproductive age in Bench Maji Zone, South West Ethiopia. Methods: A community-based cross-sectional study was conducted from December 15th, 2016 to February 15th, 2017. Multistage sampling technique was applied to select study participants. Logistic regression analysis was applied and p-values < 0.05 was used to see the significant association between dependent and independent variables. Results: A total of 330 participants were included in this study yielding 98.8% response rate. The sero-prevalence of HBsAg among women of reproductive age was 28(8.5%). Having multiple sexual partners (AOR = 18.73, 95% CI =3.65, 96.21) history of unprotected sex (AOR = 9.39, 95% CI =1.64, 53.77) were found to be significantly associated with sero-prevalence of HBV.Conclusions: The sero-prevalence of HBV infection among women of reproductive age was highly endemic. Hence, behavioral education and communication programs focusing on reduction of risky sexual behaviors should be designed to reduce HBV infection.

The Implementation of Social and Behavior Change Communication Intervention to Improve Immunization Demand: A qualitative study in Awabel District, Northwest Ethiopia

AbstractBackground: Immunization coverage in Ethiopia is low, and dropout rates are high. Social Behavior Change Communication (SBCC) interventions were introduced as a means of combating the ‘demand-side’ immunization barriers. However, Little research exists in terms of the efficacy of the SBCC intervention, in terms of promoting uptake, and improving the immunization demands in Ethiopia.Aim: To explore the current implementation status, and perceived effectiveness of SBCC intervention, barriers and facilitators with new strategies aimed at effective implementation of the SBCC intervention in Awabel District, Northwest Ethiopia.Methods: A phenomenological qualitative study was conducted from January 1- October 31, 2020. In-dept interviews were conducted with fifteen key-informants using a piloted semi-structured interview guide. Participants were purposively selected, which comprised of mangers, Expanded Program of Immunization (EPI) focal personnel, Health Extension Workers (HEWs), Women Development Armies (WDAs), mothers and community representatives. Six vaccination sessions were observed. Coding was done to identify patterns. Thematic analysis was performed using Open Code 4. 02.Results: Interpersonal communication, community conversation, social mobilization and family modeling were used as SBCC approaches. HEWs were the key source of information. Religious leaders were among the major stakeholders that encourage immunization. SBCC was perceived as an effective measure to improve immunization demand. There were multiple barriers for implementation of SBCC interventions including limited resources, lack of awareness, geographic barriers, traditional beliefs, lack of incentives, and limited EPI staff and health facility operating hours. Engagement of fathers and religious leaders, strengthening the WDA, and allocation of more resources were listed as possible strategies to tackle barriers.Conclusion: The implementation of SBCC interventions is important to improve immunization demand. Despite its effectiveness, there are several multi-level barriers to its successful implementation. Further, greater investments are required to improve infrastructures, staff employment and capacity building. [Ethiop. J. Health Dev. 2021; 35(SI-3):49-55]Keywords: Immunization, SBCC, Ethiopi

Service user involvement in mental health system strengthening in a rural African setting:qualitative study

Background: It is essential to involve service users in efforts to expand access to mental health care in integrated primary care settings in low- and middle-income countries (LMICs). However, there is little evidence from LMICs to guide this process. The aim of this study was to explore barriers to, and facilitators of, service user/caregiver involvement in rural Ethiopia to inform the development of a scalable approach.Methods: Thirty nine semi-structured interviews were carried out with purposively selected mental health service users (n = 13), caregivers (n = 10), heads of primary care facilities (n = 8) and policy makers/planners/service developers (n = 8). The interviews were audio-recorded and transcribed in Amharic, and translated into English. Thematic analysis was applied.Results: All groups of participants supported service user and caregiver involvement in mental health system strengthening. Potential benefits were identified as (i) improved appropriateness and quality of services, and (ii) greater protection against mistreatment and promotion of respect for service users. However, hardly any respondents had prior experience of service user involvement. Stigma was considered to be a pervasive barrier, operating within the health system, the local community and individuals. Competing priorities of service users included the need to obtain adequate individual care and to work for survival. Low recognition of the potential contribution of service users seemed linked to limited empowerment and mobilization of service users. Potential health system facilitators included a culture of community oversight of primary care services. All groups of respondents identified a need for awareness-raising and training to equip service users, caregivers, service providers and local community for involvement. Empowerment at the level of individual service users (information about mental health conditions, care and rights) and the group level (for advocacy and representation) were considered essential, alongside improved, accessible mental health care and livelihood interventions.Conclusion: As Ethiopia increases access to mental health care, a fundamental barrier to service user involvement is beginning to be addressed. Our study identified further barriers that need to be tackled, including a supportive political climate, and receptiveness amongst stakeholders. The findings will inform the development of a model of service user involvement, which will be piloted and evaluated

Enset landrace diversity in major enset growing regions of Southern Ethiopia

Enset [Ensete ventricosum (Welw.) Cheesman] is an important food security crop of the Southern Ethiopian highlands. The cultivation of enset is characterised by a wide variety of landraces, suitable to varying agro-ecological conditions and with multiple uses by households. The objective of this paper is to present enset landrace diversity, characteristics and uses in Ethiopia. The study was done through interviews with 375 households covering 20 communities (kebeles) and eight ethnic groups, along an altitudinal range of 1,500 to 3,000 masl across the main enset-producing belt in Southern Ethiopia. A total of 296 locally named enset landraces were recorded. Landrace presence was mostly constrained at the kebele and zone levels, with limited overlap in landrace names across these boundaries. Moderate to high enset landrace diversity was observed on farms across the entire study region. Cultivating a variety of landraces not only allowed for diversified uses, but increases the likelihood of retained yield and food security under variable environmental circumstances. Farmer experience and indigenous knowledge allow for the selection of specific landraces suited to prevalent agro-ecological conditions. We identified a perception bias in the attribution of landrace agro-ecological characteristics, with farmer insight often dependent on the environmental conditions that the local community was exposed to. We underscore the importance of research-based characterisation of enset landraces, to ensure optimal cultivation of this food security crop in changing climatic conditions

Prevalence of and Risk Factors for Trachoma in Southern Nations, Nationalities, and Peoples' Region, Ethiopia: Results of 40 Population-Based Prevalence Surveys Carried Out with the Global Trachoma Mapping Project.

PURPOSE: We sought to estimate the prevalence of trachoma at sufficiently fine resolution to allow elimination interventions to begin, where required, in the Southern Nations, Nationalities, and Peoples' Region (SNNPR) of Ethiopia. METHODS: We carried out cross-sectional population-based surveys in 14 rural zones. A 2-stage cluster randomized sampling technique was used. A total of 40 evaluation units (EUs) covering 110 districts ("woredas") were surveyed from February 2013 to May 2014 as part of the Global Trachoma Mapping Project (GTMP), using the standardized GTMP training package and methodology. RESULTS: A total of 30,187 households were visited in 1047 kebeles (clusters). A total of 131,926 people were enumerated, with 121,397 (92.0%) consenting to examination. Of these, 65,903 (54.3%) were female. In 38 EUs (108 woredas), TF prevalence was above the 10% threshold at which the World Health Organization recommends mass drug administration with azithromycin annually for at least 3 years. The region-level age- and sex-adjusted trichiasis prevalence was 1.5%, with the highest prevalence of 6.1% found in Cheha woreda in Gurage zone. The region-level age-adjusted TF prevalence was 25.9%. The highest TF prevalence found was 48.5% in Amaro and Burji woredas. In children aged 1-9 years, TF was associated with being a younger child, living at an altitude 15°C, and the use of open defecation by household members. CONCLUSION: Active trachoma and trichiasis are significant public health problems in SNNPR, requiring full implementation of the SAFE strategy (surgery, antibiotics, facial cleanliness, and environmental improvement)

Assessment of cataract surgical outcomes in settings where follow-up is poor: PRECOG, a multicentre observational study

Background Poor follow-up after cataract surgery in developing countries makes assessment of operative quality uncertain. We aimed to assess two strategies to measure visual outcome: recording the visual acuity of all patients 3 or fewer days postoperatively (early postoperative assessment), and recording that of only those patients who returned for the fi nal follow-up examination after 40 or more days without additional prompting. Methods Each of 40 centres in ten countries in Asia, Africa, and Latin America recruited 40–120 consecutive surgical cataract patients. Operative-eye best-corrected visual acuity and uncorrected visual acuity were recorded before surgery, 3 or fewer days postoperatively, and 40 or more days postoperatively. Clinics logged whether each patient had returned for the fi nal follow-up examination without additional prompting, had to be actively encouraged to return, or had to be examined at home. Visual outcome for each centre was defi ned as the proportion of patients with uncorrected visual acuity of 6/18 or better minus the proportion with uncorrected visual acuity of 6/60 or worse, and was calculated for each participating hospital with results from the early assessment of all patients and the late assessment of only those returning unprompted, with results from the fi nal follow-up assessment for all patients used as the standard. Findings Of 3708 participants, 3441 (93%) had fi nal follow-up vision data recorded 40 or more days after surgery, 1831 of whom (51% of the 3581 total participants for whom mode of follow-up was recorded) had returned to the clinic without additional prompting. Visual outcome by hospital from early postoperative and fi nal follow-up assessment for all patients were highly correlated (Spearman’s rs=0·74, p<0·0001). Visual outcome from fi nal followup assessment for all patients and for only those who returned without additional prompting were also highly correlated (rs=0·86, p<0·0001), even for the 17 hospitals with unprompted return rates of less than 50% (rs=0·71, p=0·002). When we divided hospitals into top 25%, middle 50%, and bottom 25% by visual outcome, classifi cation based on fi nal follow-up assessment for all patients was the same as that based on early postoperative assessment for 27 (68%) of 40 centres, and the same as that based on data from patients who returned without additional prompting in 31 (84%) of 37 centres. Use of glasses to optimise vision at the time of the early and late examinations did not further improve the correlations. Interpretation Early vision assessment for all patients and follow-up assessment only for patients who return to the clinic without prompting are valid measures of operative quality in settings where follow-up is poor

Remote sensing reveals how armed conflict regressed woody vegetation cover and ecosystem restoration efforts in Tigray (Ethiopia)

In recent years, armed conflicts are globally on the rise, causing drastic human and environmental harm. The Tigray war in Ethiopia is one of the recent violent conflicts that has abruptly reversed decades of ecosystem restoration efforts. This paper analyzes changes in woody vegetation cover during the period of armed conflict (2020–2022) using remote sensing techniques, supplemented by field testimony and secondary data. Extent of woody vegetation cover was analyzed using Normalized Difference Vegetation Index (NDVI) thresholding method from Sentinel 2 images in Google Earth Engine, and scale of de-electrification was qualitatively analyzed from Black Marble HD nighttime lights dataset, acquired from NASA's Black Marble team. The magnitude, direction as well as the mechanisms of change in woody vegetation cover varied across the region and over time. Tigray's woody vegetation cover fluctuated within 20% of the landmass. Mainly scattered to mountainous areas, the dry Afromontane forest cover declined from about 17% in 2020 to 15% in 2021, and 12% in 2022. About 17% of the overall decline was observed between 500 m and 2000 m elevation, where there is higher anthropogenic pressure. Land restoration practices meant to avert land degradation and desertification were interrupted and the area turned warfare ground. In many areas, forests were burned, the trees cut and the area became barren. The suspension of public services such as electricity for household or industrial use created heavy reliance on firewood and charcoal, further threatening to compound weather and climate. The magnitude of disturbance in a region that is already at a very high risk of desertification requires urgent national and international attention. Continued ecosystem disturbance could eventually make the domain part of a wider desert connecting the Sahel to the Afar Triangle, a scenario which may render the area uninhabitable.</p

The impact of incorporating surgical simulation into trichiasis surgery training on operative aspects of initial live-training surgeries

BACKGROUND: While surgical simulation is regularly used in surgical training in high-income country settings, it is uncommon in low- and middle-income countries, particularly for surgical training that primarily occurs in rural areas. We designed and evaluated a novel surgical simulator for improving trachomatous trichiasis (TT) surgery training, given that trichiasis is mostly found among the poorest individuals in rural areas. METHODOLOGY/PRINCIPAL FINDINGS: TT surgery programs were invited to incorporate surgical simulation with a new, high fidelity, low-cost simulator into their training. Trainees completed standard TT-surgery training following World Health Organization guidelines. A subset of trainees received three hours of supplemental training with the simulator between classroom and live-surgery training. We recorded the time required to complete each surgery and the number of times the trainer intervened to correct surgical steps. Participants completed questionnaires regarding their perceptions. We also assessed trainer and trainee perceptions of surgical simulation training as part of trichiasis surgery training. 22 surgeons completed standard training and 26 completed standard training plus simulation. We observed 1,394 live-training surgeries. Average time to first live-training surgery completion was nearly 20% shorter the simulation versus the standard group (28.3 vs 34.4 minutes; p = 0.02). Trainers intervened significantly fewer times during initial live-training surgeries in the simulation group (2.7 vs. 4.8; p = 0.005). All trainers indicated the simulator significantly improved training by allowing trainees to practice safely and to identify problem areas before performing live-training surgeries. Trainees reported that simulation practice improved their confidence and skills prior to performing live-training surgeries. CONCLUSIONS: A single high-fidelity surgical simulation session can significantly improve critical aspects of initial TT surgeries
