Magnitude and Associated Factors of Maternal Near Miss in Public Hospitals of Tigrai, Northern Ethiopia: A Cross Sectional Study.

The purpose of this study was to determine magnitude and associated factors of maternal near miss among women seeking obstetric and gynecologic care. A hospital based cross-sectional study design was implemented in selected public hospitals of Tigrai. Systematic random sampling method was used to select study participants. Data were entered to epi data manager version 4.1 and exported to Statistical Package for social science version 20 for analysis. Bivariate and multivariate logistic regression was used to identify factors associated with maternal near miss. The magnitude of maternal near miss was found to be 7.3%. Regression analysis showed that, mothers who reside in rural area, had distance of greater than 10 km, referred from low level health institution, and mothers had no antenatal care follow up were significantly associated with maternal near miss. Therefore, promoting antenatal care and increasing awareness in rural areas related with maternal health care services is recommended.

Evaluation of Waste Stabilization Pond Efficiency and Its Effluent Water Quality: a Case Study of Kito Furdisa Campus, Jimma University, Southwest Ethiopia.

Waste stabilization pond (WSP) technology is one of the most promising wastewater treatment methods. In developing countries, including Ethiopia, only a small proportion of the wastewater is being treated. Discharge of untreated wastewater into receiving water bodies may lead to disruption of ecological integrity, economic, and public health risks. However, there is limited evidence on WSP efficiency and effluent water quality in Ethiopia. A laboratory-based cross-sectional study was conducted on 60 wastewater samples. A standard method of procedure was used to collect and analyze samples. SPSS version-24 was used for statistical analysis and a paired t-test was used to test for statistical significant differences. A statistically significant difference (p < 0.001) in the removal efficiency of BOD5 up to 75.3% (117 mg/L effluent) and COD up to 56.5% (457.5 mg/L effluent) was recorded. A statistically significant difference (p < 0.001) in the removal efficiency of TN up to 79% (17.4 mg/L effluent), TP up to 69.2% (4.8 mg/L effluent), and PO4 -3 up to 71% (3.36 mg/L effluent) was recorded. Whereas, a statistically significant difference (p < 0.001) in the removal efficiency of total coliforms up to 99.99% (3.4 × 103 MPN/100 mL effluent) and fecal coliforms up to 94.3% (8.54 × 102 MPN/100 mL effluent) was recorded. The overall efficiency of the treatment plant was 73.5% and its water quality index of the effluent water quality of WSP was 30. The finding showed that the efficiency of the WSP was judged as satisfactory and the effluent water quality of WSP is unsuitable for the discharge into the environment. Therefore, to improve the efficiency of the WSP and to produce adequately treated water, it required adequate preliminary treatment, modification of the design, desludging of the pond, additional treatment, and frequent monitoring and maintenance of the pond.

Human Immune Deficiency Virus Serostatus and Associated Factors Among Children of Adult Index Cases in Northern Ethiopia.

INTRODUCTION: Children whose parents with human immunodeficiency virus (HIV) and family of index clients are at high risk of HIV infection. Family testing is an efficient and effective way of identifying children's HIV. The number of children becoming newly infected with HIV remains unacceptably high. This study is to assess human immune deficiency, virus serostatus, and associated factors among children of adult index cases in central Tigrai, Northern Ethiopia, 2019. METHODS: An institution-based cross-sectional study design was conducted to select a total of 454 index cases from February 01 to April 30, 2019. Data were collected from adult clients on antiretroviral treatment who have children using administered questionnaires and data extraction from the hospital antiretroviral register. Simple random sampling was used to select the index cases using the medical record number. Binary logistic regression analysis, odds ratio, and 95% confidence interval were used to determine the strength of association between dependent and independent variables. Statistical significance was declared a P-value <0.05. RESULTS: The prevalence of HIV in children from family index case testing was 8.9% with 95% CI (6.5-11.6). Female index clients [AOR=0.18, 95% CI: 06-0.55], the age of the child [AOR=0.86, 95% CI: 0.76, 0.97], importance of HIV testing [AOR=5.20, 95% CI: 2.2011.96], and discussion HIV testing [AOR=3.22, 95% CI: 1.5-16.84]. Participants who did not discuss HIV were 3.2 more likely have HIV positive child than who discussed with family members. CONCLUSION: The majority of the index clients test their children, but the prevalence rate of HIV in children from family index case testing is high. Strategies should be developed on how to communicate with household members about HIV.

Temporary Hearing Loss and Associated Factors Among Ayka Addis Textile Factory Workers in Oromia Region, Ethiopia: A Cross-Sectional Study.

INTRODUCTION: The development of modern automated machines in industries has considerably decreased the physical burden of workers in addition to increasing the productivity of the industries resulting in noise pollution. Noise exposure above the limit value of 90 dB (A) is known to cause temporary hearing loss among exposed workers. MATERIALS AND METHODS: Institutional-based cross-sectional study design was employed for a total of 406 study participants using a simple random sampling technique from January 15 to April 30, 2019. The data collection methods were observational checklist and a self-administered questionnaire. The collected data were entered into EpiData software version 4.2 and exported to SPSS software version 21 for analysis. Bivariate and multivariable logistic analyses wwere used to identify the associated factors. Statistical significance was declared using a 95% confidence interval and a p-value of less than 0.05. RESULTS: A total of 388 study participants were included in the study with a response rate of 95.6%, of which 254 (65.5%) were females. The overall temporary hearing loss among the textile factory workers was found to be 49% with COR=1.53; 95% CI (1.15-2.03). The workers from the spinning department were 2.38 times more likely to develop temporary hearing loss after exiting from work than workers from the dyeing department (95% CI= (1.16-4.90). Similarly, workers from the knitting department were 3.67 times more likely to develop temporary hearing loss after exiting from work than workers from the dyeing department (95% CI=1.42-9.47). CONCLUSION: The present study demonstrated that the workforce in the spinning and knitting departments of the textile factory had a high prevalence of temporary hearing loss than the workers in dyeing and garment working sections. Therefore, the textile factory should provide hearing protection devices to the workers.
