AIM: To identify associated factors of diabetic retinopathy(DR) screening and ey e check-up practice among diabetes mellitus(DM) patients attending Felege Hiwot Specialized ***: An institution-based cross-sectional study was applied from October 4, 2019 to January 12, 2020 at Felege Hiwot Specialized Hospital. A systematic random sampling technique was used to recruit participants and an interviewer-administered questionnaire was employed to collect the data. The collected data were entered into Epi Info version 7 and transposed to SPSS version 24 for statistical analysis. Descriptive statistics were executed and associated factors were identified using binary logistic regression. The strength of association between the independent and the outcome variable was determined using an adjusted odds ratio(AOR) with 95% confidence interval(CI). RESULTS: Four hundred and six participants partake with a response rate of 95.7% and a mean age of 47±11.5y. The magnitude of DR screening was 308(75.9%, 95%CI: 71.5%, 79.8%). Higher educational level(AOR=3.25;95%CI: 1.40, 8.78), good knowledge of DR(AOR=2.50;95%CI: 1.55, 4.46), and family history of DM(AOR=2.15;95%CI: 1.41,3.85) were significantly associated with DR screening. On the other side, rural residence [AOR=3.11(1.89, 5.02)] and undesirable attitudes toward DR [AOR=5.65(3.14, 8.76)] were significantly associated with poor regular eye checkup ***: Most of the participants are screened for DR. Higher education, family history, and good knowledge are associated with DR screening. In addition, rural residence and undesirable attitudes toward DR are associated with regular eye checkup practice.

The Impact of COVID-19 and FAIR Data Innovation on Distance Education in Africa

Prior to the advent of the COVID-19 pandemic, distance education, a mode of education that allows teaching and learning to occur beyond the walls of traditional classrooms using electronic media and online delivery practices, was not widely embraced as a credible alternative mode of delivering education, especially in Africa. In education, the pandemic, and the measures to contain it, created a need for virtual learning/teaching and showcased the potential of distance education. This article explores the potential of distance education with an emphasis on the role played by COVID-19, the technologies employed, and the benefits, as well as how data stewardship can enhance distance education. It also describes how distance education can make learning opportunities available to the less privileged, geographically displaced, dropouts, housewives, and even workers, enabling them to partake in education while being engaged in other productive aspects of life. A case study is provided on the Dutch Organisation for Internationalisation in Education(NUFFIC) Digital Innovation Skills Hub(DISH) project, which is implemented via distance education and targeted towards marginalised individuals such as refugees and displaced persons in Ethiopia,Somalia, and other conflict zones, aiming to provide them with critical and soft skills for remote work for financial remuneration. This case study shows that distance education is the way forward in education today, as it has the capability to reach millions of learners simultaneously, educating, lifting people out of poverty, and increasing productivity and yields, while ensuring that the world is a better place for future generations.

Background: Tuberculin skin test (TST)—is widely used for screening tuberculosis TB in migrants from high endemic countries of Africa and Asia. However, the cut-off point for clinical TB and Mtb infection is not well established in TB endemic countries of sub-Saharan Africa. In this study we compared the size of TST induration in smear positive pulmonary TB (PTB) patients, their house-hold contacts and community controls in high endemic setting in Ethiopia. Methods: In a health facility-based cross-sectional study, smear positive PTB patients were recruited. Their household contacts traced, and community controls were recruited from neighbourhoods. Sputum sample collected from patients were examined using smear microscopy. Participants were also tested by TST and QuantiFERON? -TB Gold In–Tube test (QFTGIT). Results: From a total of 224 study participants, skin test induration data were available for 48 PTB patients, 88 household contacts and 75 community controls. All 48 patients, 64 (72.2%) of the household contacts and 35 (46.7%) of the community controls had skin test induration ≥ 10 mm. Moreover, 44 (91.7%) PTB patients, 58 (65.9%) of the household contacts and 26 (34.7%) of the community controls had skin test induration ≥ 15 mm, respectively. The mean size of TST induration was significantly higher in TB patients (18.1mm) compared to that of household contacts (13.6 mm) and community controls (7.9 mm) (pMtb

Structure and regeneration status of Komto Afromontane moist forest, East Wollega Zone, west Ethiopia

引用

Journal of Forestry Research 2012年第2期23卷 205-216页

作者： fekadu Gurmessa Teshome Soromessa Ensermu Kelbessa Department of Biology Wollega University Addis Ababa University

We conducted a study in Komto Forest in East WoUega Zone, Oromia National Regional State, West Ethiopia for determining vegetation structure and regeneration status in this forest. We systematically sampled 53 quadrats （20 m ×20 m） along line transects radiating from the peak of Komto Mountain in eight directions. Vegetation parameters such as DBH, height, seedling and sapling density of woody species, and location and altitude of each quadrat were recorded. In total, 103 woody plant species of 87 genera and 45 families were identified. Analysis of selected tree species revealed different population structures. Generally, the forest was dominated by small trees and shrubs characteristic of secondary regeneration. Observations on the regeneration of the forest indicated that there are woody species that require urgent conservation measures. Based on the results of this study, we recommend detailed ecological studies of various environmental factors such as soil type and properties, and ethnobotanical studies to explore indigenous knowledge on uses of plants.
