Field- and laboratory-based studies on correlates of Chlamydia trachomatis transmission by Musca sorbens: Determinants of fly-eye contact and investigations into fly carriage of elementary bodies.

Musca sorbens (Diptera: Muscidae) flies are thought to be vectors of the blinding eye disease trachoma, carrying the bacterium Chlamydia trachomatis (Ct) between the eyes of individuals. While their role as vectors has been convincingly demonstrated via randomised controlled trials in The Gambia, studies of fly-borne trachoma transmission remain scant and as such our understanding of their ability to transmit Ct remains poor. We examined fly-eye contact and caught eye-seeking flies from 494 individuals (79% aged ≤9 years) in Oromia, Ethiopia. Ct-carrying flies (harbouring Ct DNA) were found to cluster spatially in and nearby to households in which at least one resident had Ct infection. Fly-eye contact was positively associated with the presence of trachoma (disease), lower human body weight and increased human body temperature. Studies of laboratory-reared M. sorbens indicated that Ct is found both externally and internally following feeds to Ct culture, with scanning electron microscopy revealing how Ct bodies can cling to fly hairs (setae). Testing for Ct on field-caught M. sorbens found fly 'bodies' (thorax, wings and abdomen) to consistently test positive for Ct while legs and heads were infrequently Ct-positive. These studies strongly support the role of M. sorbens as vectors of trachoma and highlight the need for improved understanding of fly-borne trachoma transmission dynamics and vector competence.

Prevalence of homebirth preference and associated factors among pregnant women in Ethiopia: Systematic review and meta-analysis.

BACKGROUND: Homebirth preference is the intention/plan to give birth outside health facilities with the help of unskilled birth attendants. The preference to give birth at home without a skilled birth attendant leads to care-seeking delays, intrapartum mortality, multiple stillbirths, and postpartum morbidities and mortality. Therefore, this study aimed to estimate the pooled prevalence of homebirth preference and associated factors among pregnant women in Ethiopia. METHODS: Search of Google Scholar, Medline, PubMed, Cochrane Library and Web of Science were done for this study from 20th August 2022 to 6th November 2022. For data extraction and analysis, the standardized data extraction checklist and Stata version 14 were used respectively. Sentence as "Cochrane Q test statistics and I2 statistics were used to check heterogeneity of the studies. The pooled prevalence of homebirth preference was estimated using a random-effects model. The association between homebirth preference and independent variables was determined using an odd ratio with a 95% confidence interval. A funnel plot and Egger's test were used to assess publication bias. RESULTS: A total of 976 research articles were identified. Seven studies that fulfilled eligibility criteria were included in this systematic review and meta-analysis. The pooled prevalence of homebirth preference in Ethiopia was 39.62% (95% CI 27.98, 51.26). The current meta-analysis revealed that average monthly income <1800 ETB (OR = 2.66, 95% CI 1.44, 4.90) lack of ANC follow-up (OR = 2.57, 95%CI 1.32, 5.01), being multipara (OR = 1.77, 95%CI 1.39, 2.25), poor knowledge about obstetric danger sign (OR = 5.75, 95%CI 1.o2, 32.42), and not discussing the place of delivery with a partner (OR = 5.89 (95%CI 1.1, 31.63) were significantly associated with homebirth preference. CONCLUSION: This systematic review and meta-analysis examined the substantial prevalence of homebirth preference in Ethiopia which may contribute maternal and child health crisis. The homebirth preference was associated with low average monthly income (<1800 ETB), lack of ANC follow-up, multipara, poor knowledge about obstetric danger signs, and not discussing with their partner the place of delivery. Improving knowledge of pregnant women about the benefit of health facility delivery and obstetric danger signs is necessary to decrease the prevalence of homebirth preference; for these can reduce negative outcomes occurred during delivery.

Effect of community based nutritional education on knowledge, attitude and compliance to IFA supplementation among pregnant women in rural areas of southwest Ethiopia: a quasi experimental study.

BACKGROUND: Compliance with the iron folic acid supplementation is low and not at the required level to prevent anaemia during pregnancy in many countries, including Ethiopia, even though an iron-folic acid supplementation program is being implemented. The aims of this study were to determine the effect of community-based nutritional education on knowledge, attitude, and compliance to IFA supplementation in Ilu Aba Bor zone of southwest Ethiopia. METHOD: A pretest-posttest quasi-experimental study design consisting of intervention and control group was conducted among pregnant women. The total sample size of 472, therefore, 236 pregnant women for each interventional and control group from 16 kebeles were randomly selected in two districts. A multi-stage sampling technique was used to select the study participants. Then, individual study units were selected using a simple random sampling technique and followed until the end of the study period. Effect of community-based nutritional education on knowledge, attitude, and compliance to IFA supplementation among pregnant women in rural areas were measured. RESULTS: A total of 472 pregnant women participated in the study during the baseline and 437 (92.6%) were in the study until the end. The majority (49.2%) of respondents were 21-25 years of age, with a mean age of 23.4 (SD = 3.7) years. Community-based nutrition has resulted in a statistically significant increase in levels of maternal knowledge of IFAS by 15.2% in the intervention group compared to 5.1% in the control group. Similarly, the intervention group had odds of developing a positive attitude toward IFA 5.6 (4.01, 7.85) times higher than the control group. Moreover, in this study, the odds of compliance towards IFA supplementation were 3.9 (2.67, 5.57) times higher among those who received nutrition education than those women who did not. CONCLUSION: This study revealed that community-based nutritional education can result in a significant change in knowledge, attitude, and compliance towards IFA supplementation and supports the literature suggesting the importance of the intervention to overcome the problem of poor compliance and its associated consequences.

From Neglected to Public Health Burden: Factors Associated with Podoconiosis in Resource Limited Setting in Case of Southwest Ethiopia: A Community Based Cross Sectional Study.

Background: Even though podoconiosis can cause physical, financial, and social impairments, it is commonly overlooked by organizations, and one-fourth of the predicted worldwide burden will fall on Ethiopia. In spite of this, there are only a few attempts for prevention and control in certain areas in Ethiopia. Updated statistics on prevalence and contributing factors could make local efforts at prevention, control, and rehabilitation more effective. Thus, this study was aimed to assess the prevalence of podoconiosis and its associated factors among Ilu Aba Bor zone residents, South West Ethiopia. Methods: A community-based cross-sectional study was conducted on 491 participants from March 25 to April 25, 2022. Data were entered into Epi-Data version 4.6.0, then exported to SPSS version 25 for final analysis. In the bi-variable regression, variables with P-values less than 0.25 were included in the multivariable model. Finally, multivariable logistic regression was performed to identify factors associated with podoconiosis at a 5% level of significance. Results: In this study area, podoconiosis prevalence was found to be 5.7% [3.6-7.2]. In multivariable regression model, lower tertile wealth status [AOR=2.09; (95% CI (1.384, 5.343)], no formal education [AOR=2.23; (95% CI; 1.179-3.820)] and average distance to reach water source to home [AOR=2.061; (95% CI: 1.78-7.35)] were significantly associated podoconiosis. Conclusion and Recommendation: According to this study, one in every seventeen individuals had podoconiosis, which is a significant prevalence when compared to earlier studies. Podoconiosis was observed to be associated with factors like wealth status, educational attainment, and distance from water source. To address this public health issue, strong preventive and therapeutic treatments should be used.

Why health system diagnosis delay among tuberculosis patients in Illubabor, Oromia region, South West Ethiopia? A qualitative study.

BACKGROUND: The main target of tuberculosis control and prevention is to detect incident cases as quickly as possible and also to prevent the occurrence of disease. It is also the responsibility of the health facility to screen the contacts, identifying children for prophylactic therapy. However, the target is difficult to meet due to issues within health facilities that cause health system diagnostic delays. Despite this, there is no information explored why health system diagnostic delays among tuberculosis patients. METHOD: A qualitative study was conducted by using different data collection methods and sources. Seventeen DOT providers, five laboratory professionals, six program managers, and seven Tuberculosis patients were interviewed. In addition, 22 governmental health facilities were observed for the availability of resources. Data obtained from the in-depth interviews was transcribed, coded, categorized, and thematized manually. RESULT: Health system Diagnosis delays reasons were related with sample collection procedures, poor competency of health professionals, in addition to absences or scarcity of health professionals, medical products, and basic infrastructure. We found 18 health facilities without skilled personnel in the OPD, 7 health facilities with a broken microscope, and almost all health facilities without a separate room for sputum examination. Furthermore, 12 (54.5%) and 14 (63.6%) health facilities lacked access to water and electric power, respectively. CONCLUSION: Many reasons for TB diagnosis delays have been identified in the study area. Poor competence of health workers and scarcity of resources were identified. Depending on the finding, we suggest strengthening the health workers' training. Concrete strategies need to be designed to retain professionals. Training on human resource planning and budget preparation is needed for front-line managers. Managers have to work on the maintenance of diagnostic tools and facilitate transportation. The rural health facilities need to use another alternative power source.

Access to maternal health services during COVID-19 pandemic, re-examining the three delays among pregnant women in Ilubabor zone, southwest Ethiopia: A cross-sectional study.

BACKGROUND: All women require access to high-quality care during pregnancy, labor, and after childbirth. The occurrence of delay at any stage is one of the major causes of maternal mortality. There is, however, a scarcity of data on women's access to maternal health services during the COVID-19 pandemic. Therefore, the goal of this study was to assess the magnitude of delays in maternal health service utilization and its associated factors among pregnant women in the Ilubabor zone during the COVID-19 pandemic. METHODS: A facility-based cross-sectional study was conducted among 402 pregnant women selected by systematic random sampling. Data were analyzed using IBM SPSS Statistics version 26. Descriptive and summary statistics were used to describe the study population. Bivariate and multivariable logistic regression analyses were performed to identify factors associated with the outcome variables. Adjusted odds ratio with respective 95% CI was used to report significant covariates. RESULTS: A total of 402 pregnant women participated in this study. The median age of the respondents was 25 years (IQR = 8). On average, a woman stays 1.76 hours (SD = 1.2) to make a decision to seek care. The prevalence of first, second and third delay were 51%, 48%, and 33.3%, respectively. Being unmarried [AOR (95% CI)], [0.145 (0.046-0.452)], being unemployed [AOR (95% CI)], [4.824 (1.685-13.814)], age [AOR (95% CI)], [0.227 (0.089-0.0579)], fear of COVID-19 [AOR (95% CI)], [1.112 (1.036-1.193)], urban residence [AOR (95% CI)], [0.517 (0.295-0.909)], and lack of birth preparedness [AOR (95% CI)], [6.526 (1.954-21.789)] were significantly associated with first delay. Being unmarried [AOR (95% CI)], [5.984 (2.930-12.223)], being unemployed [AOR (95% CI)], [26.978 (3.477-209.308)], and age [AOR (95% CI)], [0.438 (0.226-0.848)] were significantly associated with second delay. Having lengthy admission [AOR (95% CI)], [7.5 (4.053-13.878)] and non-spontaneous vaginal delivery [AOR (95% CI)], [1.471 (1.018-1.999)] were significantly associated with third delay. CONCLUSION: This study identified a significant proportion of mothers experiencing delays, although there were no data to suggest exacerbated delays in utilizing maternal health services due to fear of the COVID-19 pandemic. The proportion of maternal delay varies with different factors. Improving the decision-making capacity of women is, therefore, essential.

Predictors of adverse perinatal outcome among women who gave birth at Medical Center of Southwest Ethiopia: a retrospective cohort study.

OBJECTIVES: The aim of this study was to determine predictors of adverse perinatal outcome among women who gave birth at Medical Center of Southwest Ethiopia. SETTING: Institutional based retrospective cohort study was conducted among women who gave birth at Medical Center of Southwest Ethiopia. PARTICIPANTS: Medical record of 777 women was included in the study by using maternity HMIS logbook as entry point. Simple random sampling technique without replacement was employed to select individual medical record using computer generated random numbers. PRIMARY OUTCOME MEASURED: Predictors of adverse perinatal outcome were examined using modified Poisson regression with a robust SE. RESULTS: Majority, 74.1% of the participants were in the age group of 21-34 years and the median age was 26 (IQR=7) years. More than one-third, 35.9% of the mothers were primigravida and only 21.2% of them had above four antenatal cares (ANC) visit. The overall incidence of adverse perinatal outcome was 31.5% (95% CI: 28.3 to 34.9). Maternal age less than 20 years (adjusted risk ratio, aRR=1.3; 95% CI: 1.01 to 1.5), rural residence (aRR=1.27; 95% CI: 1.04 to 1.59), presence of antepartum haemorrhage in current pregnancy (aRR=1.7; 95% CI: 1.38 to 2.07), maternal anaemia (aRR=1.25; 95% CI: 1.03 to 1.53), lack of ANC visit (aRR=2.29; 95% CI: 1.35 to 3.90), induced labour (aRR=1.77; 95% CI: 1.43 to 2.19) and being positive for venereal disease research laboratory (VDRL) test in current pregnancy (aRR=2.0; 95% CI: 1.16 to 3.38) were found to be significantly associated with adverse perinatal outcome. CONCLUSION: The incidence of adverse perinatal outcome in the study area is high and maternal age less than 20, rural residency, maternal anaemia, antepartum haemorrhage in the current pregnancy, inadequate ANC visit, induction of labour and being positive for VDRL test were found to predict occurrence of adverse perinatal outcome. Majority of these problems can be managed by providing quality antenatal, intrapartum and post-natal care.

Perinatal outcomes of women with hypertensive disorders of pregnancy in Jimma Medical Center, southwest Ethiopia: Retrospective cohort study.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) increases adverse perinatal outcomes in women with the disorder. About 16% of all still births and 10% of early neonatal deaths are accounted by HDP. In Ethiopia, HDP complicates about 6% of all pregnancies. Hence, the objective of this study was to determine the risk of adverse perinatal outcomes among women with HDP in Jimma Medical Center, southwest Ethiopia. METHODS: A retrospective cohort study was conducted on a total of 777 women who gave birth from June 2017 to March 2020 at Jimma Medical Center, southwest Ethiopia. Women with HDP and normotensive women who gave birth at or after 28 weeks of gestation were enrolled as exposed and unexposed respectively. Simple random sampling technique was used to select study participants. Data were reviewed using structured data collection performa that was prepared after reviewing relevant literatures. Data were entered to Epi-Data then exported to STATA version 13 for analysis. The adverse perinatal outcomes risk were examined using log binomial and modified Poisson regression model with robust standard errors. RESULTS: In this study, the overall incidence of adverse perinatal outcome was higher among women with hypertensive disorders of pregnancy (HDP) than normotensive women (64.1% versus 32.8%). After adjusting for confounders, women with HDP were at higher risk of babies with low birth weight (adjusted RR = 2.88 (2.2, 3.75)), preterm birth(aRR = 2.31(1.7, 3.14)), fifth minute low Apgar score (aRR = 2.6(1.53, 4.42)), admission to neonatal intensive care unit (aRR = 1.77(1.32, 2.37), stillbirth (aRR = 2.02(1.11, 3.01)), and perinatal mortality (aRR = 3.88(1.97, 7.66)) than normotensive women. CONCLUSION: Women with hypertensive disorder of pregnancy were at higher risk of adverse perinatal outcomes than normotensive women who gave birth at Jimma Medical Center, southwest Ethiopia. Therefore, health care providers should strengthen prevention, early diagnosis and prompt management of HDP in order to reduce adverse perinatal outcomes.

Towards an odour-baited trap to control Musca sorbens, the putative vector of trachoma.

Musca sorbens is a synanthropic filth fly that aggressively attacks people to feed from mucous membranes of the eyes, nose or mouth, from open sores, or from sweat. It has long been suspected that this fly contributes to the transmission of eye infections, particularly trachoma, and recent work has added to the evidence base that M. sorbens is a trachoma vector in Ethiopia. There are few options to control M. sorbens, largely due to a lack of evidence. Space spraying with insecticides is effective, but an environmentally sound and long-term sustainable solution would be better, for example, mass trapping. We tested commercially available and homemade trap types in a pilot (laboratory) study and three field studies. A homemade design, built from a bucket and two empty water bottles, baited with a commercially available lure, The Buzz, was found to be most effective. This trap caught 3848 M. sorbens over 26 trap 'events' (3- or 4-day periods); mean/median per 24 h 43.6 (standard deviation 137.10)/2.25 (IQR 0.25-12.67). The Buzz lure is cheap and effective for 4 weeks, and trap components cheap and locally available. Further studies are needed to understand the impact of this trap on local fly populations and the local transmission of trachoma.
