Postoperative trachomatous trichiasis and associated factors among adults who underwent trachomatous trichiasis surgery in Ambassel District, North-East Ethiopia.

BACKGROUND: In Trachoma endemic countries, many people who underwent Trichiasis surgery faced a recurrence of the disease. Postoperative Trichiasis is a significant problem for patients and health care providers because it puts the eye at renewed risk of sight loss. Despite the low utilization of Trachomatous Trichiasis surgery and the high recurrence rate, evidence that elucidate why it recurs after surgery is limited. This study was aimed to assess the magnitude and associated factors of postoperative Trichiasis among 18 years and above individuals who underwent Trachomatous Trichiasis surgery between 2013 and 2019 in Ambassel District, Northeast Ethiopia, 2020. METHODS: The community-based cross-sectional study design was conducted from March 10 to March 23/2020 in selected kebeles of Ambassel District. The required sample size (506) was calculated using EPI-INFO Version 7. A multi-stage sampling technique was used to employ study participants. Data were collected through the interviewer-administered structured pre-tested questionnaire and entered into EpiData version 3.1 and then exported to SPSS version 23.0 for analysis. Bi-variable and multivariable logistic regression models were fitted to identify associated factors of Postoperative Trachomatous Trichiasis. RESULTS: Four hundred ninety two individuals participated in this study with a response rate of 97.2%. In Ambassel district, the prevalence of postoperative Trichiasis was 23.8% (95% CI = 19.9-27.8). Among associated factors of postoperative Trachomatous Trichiasis: age 50-59 (AOR = 3.34, CI = 1.38-8.1), 60-69 (AOR = 3.24, CI = 1.38-7.61), ≥70 years (AOR = 6.04, CI = 2.23-16.41), duration since surgery (AOR = 1.7, CI = 1.35-2.14), complication (AOR = 2.98, CI = 1.24-7.2), washing the face two times (AOR = 0.25, CI = 0.13-0.47), washing the face three and more times (AOR = 0.1, CI = 0.41-0.25), taking Azithromycin following surgery (AOR = 0.19, CI = 0.09-0.41), pre-operative epilation history (AOR = 2.11, CI = 1.14, 3.9) and having a knowledge about TrachomaTtrichiasis (AOR = 0.21, CI = 0.08-0.58) showed a statistical significant association. CONCLUSIONS: The prevalence of postoperative Trichiasis in Ambassel District was higher than most Ethiopian studies. Age, frequency of face washing, medication following surgery, duration since the last surgery, knowledge about trachoma, pre-operative epilation history, and complication after surgery were identified to be independent factors. To minimize postoperative Trachomatous Trichiasis stakeholders need to consider health education for patients, provision of Azithromycin after surgery, and proper training for integrated eye care workers.

Evaluating land suitability and water availability for surface irrigation in the Abbay basin of Ethiopia.

This study was conducted in the Abbay basin of Ethiopia to evaluate land suitability for irrigation considering both surface and groundwater sources using the analytic hierarchy process. Multiple factors which affect irrigated agriculture productivity were considered, and an 85% threshold was applied to identify irrigable land. The suitability result was validated using ground truth data from existing irrigation projects for surface water sources and depth to groundwater data for groundwater sources. The low flow potential of rivers, which is dependable for surface irrigation, was evaluated against suitable land considering the most dominant crops. The result showed that nearly 10% of the basin area (19 192 km2) and 5.3% of the basin (10 364 km2) were found suitable for surface irrigation from rivers and groundwater, respectively. South Gojam was found to be the most suitable sub-basin (approx. 3880 km2) for surface irrigation, whereas Muger was found to be the most suitable sub-basin (approx. 2105 km2) for surface irrigation from rivers and groundwater, respectively. Depth to groundwater was shallow for Muger as compared with other sub-basins. The validation result depicted more than 83% and 73% overlap for surface and groundwater sources, respectively. Land suitability and water availability assessment result in the Abbay basin shows a promising result for surface irrigation developments.

Contraceptive Use and Its Associated Factors among Women Who Gave Birth within 12 Months in Dubti Town, Pastoral Community, of Afar Region Northeast, Ethiopia.

Introduction: Substantial numbers of women are not using contraceptives in their postpartum period and die due to avoidable causes related to birth complications. Contraceptives use within 12 months of childbirth has given less attention in Ethiopia. Thus, this study is aimed to assess contraceptive use and its associated factors among women who gave birth within 12 months in Dubti town, pastoral community of Afar region, Ethiopia. Methods: A community-based cross-sectional study was conducted among 342 women in the Dubti town. A systematic random sampling technique was employed to identify and enroll women. Data were collected using a pretested, structured, and interviewer-administered questionnaire. Descriptive statistics were done, and logistic regression analysis was employed to identify the factors associated with contraceptive use. The statistical association was measured by odds ratio with a 95% confidence interval. p value < 0.05 was considered as statistically significant. Results: In this study, 103 (30.1%) [95% CI: 25.4%, 35.1%] women have used contraceptives. Women who had secondary educational level (AOR = 3.53, 95% CI (1.68, 7.36), had antenatal care follow-up (AOR = 1.93, 95% CI (1.01, 3.69), and visited by health worker after delivery (AOR = 2.54, 95% CI (1.37, 4.68) were associated with increased odds of contraceptives use. Conclusions: This study revealed that the prevalence of contraceptive use was low compared to the national recommended figure. Secondary educational level, having antenatal care follow-up, and being visited by health workers after delivery were predictors of contraceptive use. Thus, increase the educational status of women, antenatal care follow-up service, and visiting after delivery by health workers are important interventions to promote the use of contraceptives in the postpartum period.

Insights From a Multi-Method Recharge Estimation Comparison Study.

Although most recharge estimation studies apply multiple methods to identify the possible range in recharge values, many do not distinguish clearly enough between inherent uncertainty of the methods and other factors affecting the results. We investigated the additional value that can be gained from multi-method recharge studies through insights into hydrogeological understanding, in addition to characterizing uncertainty. Nine separate groundwater recharge estimation methods, with a total of 17 variations, were applied at a shallow aquifer in northwest Ethiopia in the context of the potential for shallow groundwater resource development. These gave a wide range of recharge values from 45 to 814 mm/a. Critical assessment indicated that the results depended on what the recharge represents (actual, potential, minimum recharge or change in aquifer storage), and spatial and temporal scales, as well as uncertainties from application of each method. Important insights into the hydrogeological system were gained from this detailed analysis, which also confirmed that the range of values for actual recharge was reduced to around 280-430 mm/a. This study demonstrates that even when assumptions behind methods are violated, as they often are to some degree especially when data are limited, valuable insights into the hydrogeological system can be gained from application of multiple methods.
