Khat chewing and its associated factors among pregnant women in Chiro district, eastern Ethiopia: a community-based study
IntroductionDespite its deleterious consequences, khat chewing is escalating worldwide. However, there is a lack of evidence about the extent of khat chewing among pregnant women in Ethiopia, particularly in the current study area. Therefore, this study aimed to assess the prevalence of current khat chewing and its associated factors among pregnant women in Chiro district, eastern Ethiopia.MethodsThis community-based cross-sectional study was conducted in Chiro district from November 1 to 30, 2022 G.C. Study participants were selected using the systematic random sampling technique. An interview-administered structured questionnaire was used to collect data through a house-to-house survey. The data were entered into EpiData version 3.1 and analyzed in STATA 14 software. Characteristics of study participants were summarized using descriptive analysis, and binary logistic regression was used to identify determinants of khat chewing.ResultsA total of 409 pregnant women participated in this study, with a response rate of 99%. The overall prevalence of khat chewing was 60.4% (95% CI: 55.5%, 65.2%). Religion (AOR: 2.08; 95% CI: 1.13, 3.82), khat cultivation (AOR: 0.43; 95% CI: 0.25, 0.77), partner khat use (AOR: 5.54; 95% CI: 3.11, 9.88), pre-pregnancy khat use (AOR: 9.95; 95% CI: 5.55, 17.81), antenatal care (ANC) visit (AOR: 2.71; 95% CI: 1.41, 5.21), and mental distress (AOR: 4.89; 95% CI: 2.38, 10.02) were significantly associated with current khat chewing.ConclusionThe majority of pregnant women in the study area practice khat chewing. Thus, accessible and comprehensive pre-conception and pre-natal care incorporating the prevention and management of antenatal khat chewing is crucial to overcome this problem. Provision of mental healthcare involving partners of pregnant women is also important to reduce the extent and impacts of khat chewing during pregnancy. Further longitudinal studies triangulated with qualitative designs are recommended
Women's Independent Household Decision Making Power and its influence on their Autonomy in relation to Child Vaccinations: a mixed-method study among Women of Reproductive Age in Northwest Ethiopia
AbstractBackground: The importance of women’s empowerment in influencing health outcomes has received attention globally, but there is limited information in Ethiopia on the relationship between women's household decision making power and the autonomy of decision making in relation to child vaccinations.Aim: The study aimed to assess the role of women's household decision making power on their autonomy in relation to child vaccinations.Methods: A community based mixed method study design was conducted among women who had 12–23-month-old children in Wogera district, Ethiopia. The sample size was determined using a single population proportion formula for the quantitative aspect of the study and the data collection for the qualitative study continued until saturation. The quantitative data was collected using a piloted questionnaire. SPSS software was used for quantitative data analyses. X2-square test was conducted to explore the association between women's household decision making power and their autonomy in relation to decision making around child vaccinations. Framework analysis was employed to analyse qualitative data using open code software.Results: A total of 584 women participated in the quantitative study and 13 In-depth interviews (IDI) with 13 key informants (KII)were conducted for the qualitative study. Majority, 88.2% (95% CI: 85.7, 90.6) of the respondents have autonomy to vaccinate children. This study showed that nearly two-thirds, 61.6% of the women had household decision making power. Respondents of the qualitative study noted that women had low household decision making power. Women's household decision making power is associated with women's autonomy to vaccinate children (x2=92.775a, df=1, P<0.001).Conclusions: The overall level of women’s household decision making power was relatively low compared to EDHS reports whereas women's autonomy to chid vaccination was high. There was a strong relationship between women’s household decision making power and their autonomy in relation to child vaccinations. It is therefore important to implement activities, for example, provision of behavioural change communication (BCC) in the community, that can improve women’s household decision making power which in turn will influence child vaccination coverage.

Diagnostic accuracy of three commercially available one step RT-PCR assays for the detection of SARS-CoV-2 in resource limited settings
Background
COVID-19 is an ongoing public health pandemic regardless of the countless efforts made by various actors. Quality diagnostic tests are important for early detection and control. Notably, several commercially available one step RT-PCR based assays have been recommended by the WHO. Yet, their analytic and diagnostic performances have not been well documented in resource-limited settings. Hence, this study aimed to evaluate the diagnostic sensitivities and specificities of three commercially available one step reverse transcriptase-polymerase chain reaction (RT-PCR) assays in Ethiopia in clinical setting.
Methods
A cross-sectional study was conducted from April to June, 2021 on 279 respiratory swabs originating from community surveillance, contact cases and suspect cases. RNA was extracted using manual extraction method. Master-mix preparation, amplification and result interpretation was done as per the respective manufacturer. Agreements between RT-PCRs were analyzed using kappa values. Bayesian latent class models (BLCM) were fitted to obtain reliable estimates of diagnostic sensitivities, specificities of the three assays and prevalence in the absence of a true gold standard.
Results
Among the 279 respiratory samples, 50(18%), 59(21.2%), and 69(24.7%) were tested positive by TIB, Da An, and BGI assays, respectively. Moderate to substantial level of agreement was reported among the three assays with kappa value between 0 .55 and 0.72. Based on the BLCM relatively high specificities (95% CI) of 0.991(0.973–1.000), 0.961(0.930–0.991) and 0.916(0.875–0.952) and considerably lower sensitivities with 0.813(0.658–0.938), 0.836(0.712–0.940) and 0.810(0.687–0.920) for TIB MOLBIOL, Da An and BGI respectively were found.
Conclusions
While all the three RT-PCR assays displayed comparable sensitivities, the specificities of TIB MOLBIOL and Da An were considerably higher than BGI. These results help adjust the apparent prevalence determined by the three RT-PCRs and thus support public health decisions in resource limited settings and consider alternatives as per their prioritization matrix
Assessing the climate resilience of community-managed water supplies in Ethiopia and Nepal
Understanding the resilience of water supplies to climate change is becoming an urgent priority to ensure health targets are met. Addressing systemic issues and building the resilience of community-managed supplies, which serve millions of people in rural LMIC settings, will be critical to improve access to safe drinking water. The How Tough is WASH (HTIW) framework to assess resilience was applied to community-managed water supplies in Ethiopia and Nepal to assess the effectiveness of this framework in field conditions. The resilience of these water supplies was measured along six domains—the environment, infrastructure, management, institutional support, community governance and supply chains—that can affect how they respond to climate change effects. We found that the HTIW framework provided an objective measure of resilience and could be used to rank water supplies in order of priority for action. We also found that systemic issues could be identified. The tools and methods used in the framework were easy to deploy by field research teams. The water supplies studied in Ethiopia and Nepal had low to moderate resilience to climate change. Service management and institutional support were weak in both countries. The data from Ethiopia and Nepal suggests that many water supplies in rural and small-town communities are unlikely to be resilient to future climate change without increased investment and support. The use of simple frameworks such as HTIW will be important in supporting decisions around such investments by identifying priority communities and actions
Open defecation practice among households with latrines in rural communities of Ararso District, Somali Region, Eastern Ethiopia
BackgroundOpen defecation contributes to the spread of different feco-oral diseases. Therefore, access to a latrine is strongly recommended, as it considerably reduces the risks. Even though provision of latrine facilities alone does not guarantee the desired health benefits, they should be integrated with behavior change. In Ethiopia, efforts have been made to increase the coverage of latrine facilities. However, evidence on how consistently households use it is limited. Most prior studies focused on latrine utilization among households, and limited evidence is available about open defecation practices among households with latrines and associated factors. Thus, this study is critical for developing effective intervention approaches to prevent open defecation among households with latrines.ObjectiveThe aim of this study was to assess the open defecation practice and associated factors among households with latrines in rural communities of Ararso District, Somali Region, Eastern Ethiopia, 2023.MethodA community-based, cross-sectional study design was employed among households with latrines in the district. A total of 632 households latrines were selected using a systematic sampling technique. Data were collected using a structured questionnaire and an observational checklist. The questionnaire was designed in KoboTool box, Humanitarian Response software, and the data were collected using the Kobo Collect version 2023.2.4 mobile application. The data were downloaded from the server in the Microsoft Excel format for data cleaning before being exported to STATA version 14 for analysis. Bivariate and multivariable analyses were employed to investigate the relationship between outcome and independent variables. Odd ratios with 95% confidence intervals were utilized to assess the association between the outcome and the predictor variables. A P-value of <0.05 was used as the threshold point for statistical significance.ResultIn this study, the prevalence of open defecation practice among households with latrines was 32.4% (95% CI: 28.1, 35.9). Sex of the household (AOR = 1.60, 95% CI: 1.06, 2.4), educational status (AOR = 2.40, 95% CI: 1.08, 5.53), family size (AOR = 1.62, 95% CI: 1.22, 2.78), the presence of under-5-year-old children in the house (AOR = 1.84, 95% CI: 1.19, 2.75), the need for latrine maintenance (AOR = 2.37.95% CI: 1.62, 3.48), current status of the latrine (AOR = 2.37, 95% CI: 1.62, 3.48), and latrine cleanness status (being unclean) (AOR = 1.91, 95% CI: 1.29, 2.81) were significantly associated with open defecation practice among households with latrine.ConclusionThe study concluded that open defecation was significantly practiced by households with latrines. This revealed that the presence of a latrine alone was insufficient to considerably reduce open defecation. To alleviate this problem, the government and health workers, in collaboration with the health bureau, should promote frequent sanitation and hygiene education in the communities
Prognostic Value of C-Reactive Protein in SARS-CoV-2 Infection: A Simplified Biomarker of COVID-19 Severity in Northern Ethiopia
Purpose
To evaluate the role of C-reactive protein (CRP) in predicting severe COVID-19 patients.
Methods
A prospective observational cohort study was conducted from July 15 to October 28, 2020, at Kuyha COVID-19 isolation and treatment center hospital, Mekelle City, Northern Ethiopia. A total of 670 blood samples were collected serially. SARS-CoV-2 infection was confirmed by RT-PCR from nasopharyngeal swabs and CRP concentration was determined using Cobas Integra 400 Plus (Roche). Data were analyzed using STATA version 14. P-value < 0.05 was considered statistically significant.
Results
Overall, COVID-19 patients had significantly elevated CRP at baseline when compared to PCR-negative controls [median 11.1 (IQR: 2.0– 127.8) mg/L vs 0.9 (IQR: 0.5– 1.9) mg/L; p=0.0004)]. Those with severe COVID-19 clinical presentation had significantly higher median CRP levels compared to those with non-severe cases [166.1 (IQR: 48.6– 332.5) mg/L vs 2.4 (IQR: 1.2– 7.6) mg/L; p< 0.00001)]. Moreover, COVID-19 patients exhibited higher median CRP levels at baseline [58 (IQR: 2.0– 127.8) mg/L] that decreased significantly to 2.4 (IQR: 1.4– 3.9) mg/L after 40 days after symptom onset (p< 0.0001). Performance of CRP levels determined using ROC analysis distinguished severe from non-severe COVID-19 patients, with an AUC value of 0.83 (95% CI: 0.73– 0.91; p=0.001; 77.4% sensitivity and 89.4% specificity). In multivariable analysis, CRP levels above 30 mg/L were significantly associated with an increased risk of developing severe COVID-19 for those who have higher ages and comorbidities (ARR 3.99, 95% CI: 1.35– 11.82; p=0.013).
Conclusion
CRP was found to be an independent determinant factor for severe COVID-19 patients. Therefore, CRP levels in COVID-19 patients in African settings may provide a simple, prompt, and inexpensive assessment of the severity status at baseline and monitoring of treatment outcomes
Longitudinal profile of antibody response to SARS-CoV-2 in patients with COVID-19 in a setting from Sub-Saharan Africa: A prospective longitudinal study.
BACKGROUND
Serological testing for SARS-CoV-2 plays an important role for epidemiological studies, in aiding the diagnosis of COVID-19, and assess vaccine responses. Little is known on dynamics of SARS-CoV-2 serology in African settings. Here, we aimed to characterize the longitudinal antibody response profile to SARS-CoV-2 in Ethiopia.
METHODS
In this prospective study, a total of 102 PCR-confirmed COVID-19 patients were enrolled. We obtained 802 plasma samples collected serially. SARS-CoV-2 antibodies were determined using four lateral flow immune-assays (LFIAs), and an electrochemiluminescent immunoassay. We determined longitudinal antibody response to SARS-CoV-2 as well as seroconversion dynamics.
RESULTS
Serological positivity rate ranged between 12%-91%, depending on timing after symptom onset. There was no difference in positivity rate between severe and non-severe COVID-19 cases. The specificity ranged between 90%-97%. Agreement between different assays ranged between 84%-92%. The estimated positive predictive value (PPV) for IgM or IgG in a scenario with seroprevalence at 5% varies from 33% to 58%. Nonetheless, when the population seroprevalence increases to 25% and 50%, there is a corresponding increases in the estimated PPVs. The estimated negative-predictive value (NPV) in a low seroprevalence scenario (5%) is high (>99%). However, the estimated NPV in a high seroprevalence scenario (50%) for IgM or IgG is reduced significantly to 80% to 85%. Overall, 28/102 (27.5%) seroconverted by one or more assays tested, within a median time of 11 (IQR: 9-15) days post symptom onset. The median seroconversion time among symptomatic cases tended to be shorter when compared to asymptomatic patients [9 (IQR: 6-11) vs. 15 (IQR: 13-21) days; p = 0.002]. Overall, seroconversion reached 100% 5.5 weeks after the onset of symptoms. Notably, of the remaining 74 COVID-19 patients included in the cohort, 64 (62.8%) were positive for antibody at the time of enrollment, and 10 (9.8%) patients failed to mount a detectable antibody response by any of the assays tested during follow-up.
CONCLUSIONS
Longitudinal assessment of antibody response in African COVID-19 patients revealed heterogeneous responses. This underscores the need for a comprehensive evaluation of seroassays before implementation. Factors associated with failure to seroconvert needs further research
Effect of co-infection with intestinal parasites on COVID-19 severity: A prospective observational cohort study
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection results in a spectrum of clinical presentations. Evidence from Africa indicates that significantly less COVID-19 patients suffer from serious symptoms than in the industrialized world. We and others previously postulated a partial explanation for this phenomenon, being a different, more activated immune system due to parasite infections. Here, we aimed to test this hypothesis by investigating a potential correlation of co-infection with parasites with COVID-19 severity in an endemic area in Africa.
Methods: Ethiopian COVID-19 patients were enrolled and screened for intestinal parasites, between July 2020 and March 2021. The primary outcome was the proportion of patients with severe COVID-19. Ordinal logistic regression models were used to estimate the association between parasite infection, and COVID-19 severity. Models were adjusted for sex, age, residence, education level, occupation, body mass index, and comorbidities.
Findings: 751 SARS-CoV-2 infected patients were enrolled, of whom 284 (37.8%) had intestinal parasitic infection. Only 27/255 (10.6%) severe COVID-19 patients were co-infected with intestinal parasites, while 257/496 (51.8%) non-severe COVID-19 patients were parasite positive (p<0.0001). Patients co-infected with parasites had lower odds of developing severe COVID-19, with an adjusted odds ratio (aOR) of 0.23 (95% CI 0.17–0.30; p<0.0001) for all parasites, aOR 0.37 ([95% CI 0.26–0.51]; p<0.0001) for protozoa, and aOR 0.26 ([95% CI 0.19–0.35]; p<0.0001) for helminths. When stratified by species, co-infection with Entamoeba spp., Hymenolepis nana, Schistosoma mansoni, and Trichuris trichiura implied lower probability of developing severe COVID-19. There were 11 deaths (1.5%), and all were among patients without parasites (p = 0.009).
Interpretation: Parasite co-infection is associated with a reduced risk of severe COVID-19 in African patients. Parasite-driven immunomodulatory responses may mute hyper-inflammation associated with severe COVID-19.
