Synthetic colorants used for dye and mordant purposes in textile industries are currently causing environmental problems in the world. The usage of these synthetic colorants is a major health problem ...and harms the environment. For this reason, synthetic colorants should be replaced by natural colorants. Therefore, this study aimed to extract natural dye stuff from spent coffee ground and bio-mordant from mango bark. The raw materials were collected, washed, dried, crushed and their physico-chemical properties were determined. Finally, the samples were extracted by using the solvent extraction method. During the extraction process, the central composite design method (CCD) was used to analyze and optimize the effect of dosage (g/l), temperature (℃) and time (min). The maximum natural dye yield value of 18.41% was obtained at a dosage of 60 g/l, temperature of 70°C and time of 90 min. Also, the highest natural mordant yield of 19.03% was achieved at the value of 45 g/l, 70°C and 90 min. The fastness properties of dyed and mordanted cotton fabric results were within a range of acceptable standard values. Therefore, using spent coffee grounds for natural dyes and mango bark for natural mordant can be a feasible commercial alternative to synthetic dyes in textile and dyeing industries.
Wastewater treatment with chemical coagulants has a variety of drawbacks, including sludge management, cost, concerns for human health, and environmental pollution. In light of this, a study was ...conducted to determine whether banana plant stem (Musa acuminate) made coagulant can effectively reduce turbidity (NTU) of wastewater. In this study, conventional extraction method was used to extract the coagulant from the banana plant stem by using NaCl (0.1, 0.5, 1 M) solvent. After extraction, the coagulation efficiency of each produced coagulant was computed in terms of their turbidity removal efficiency (%) from sampled wastewater. The sampled wastewater had an average turbidity value of 893 NTU. Response surface methodology (RSM) and central composite design (CCD) were used to study the effects of NaCl solvent concentration (M), extraction time (min), and particle size (mm) on the coagulation efficiency (%) of the extracted coagulant. In addition, the coagulant was characterized such as FTIR analysis, point of zero charge value determination, and inulin compound presence analysis. From all prepared coagulants, the maximum coagulation efficiency obtained was 86.3% at the optimum conditions, such as 0.55 M (NaCl) of solvent concentration, 1.25 mm particle size, and 20 min of extraction time. The characterized coagulant had 6.2 points of zero charge value and also had various types of functional groups. Based on the findings of this study, it can be said that the coagulant prepared from banana stems (Musa acuminate) was an efficient natural coagulant that could be applied to treat wastewater.
The prevalence of diabetes, dyslipidemias, and high blood pressure is increasing worldwide especially in low and middle income countries. World Health Organization has emphasized the importance of ...the assessment of the magnitude of the specific disease in each country. We determined the prevalence and determinant factors of high blood pressure, hyperglycemia, dyslipidemias and metabolic syndrome in Ethiopia. A community based survey was conducted from -April to June 2015 using WHO NCD STEPS instrument version 3.1. 2008. Multistage stratified systemic random sampling was used to select representative samples from 9 regions of the country. A total of 10,260 people aged 15-69 years participated in the study. Blood pressure (BP) was measured for 9788 individuals. A total of 9141 people underwent metabolic screening. The prevalence of raised blood pressure (SBP ≥140 and/or DBP ≥ 90 mmHg) was 15.8% (16.3% in females and 15.5% in males). The prevalence of diabetes mellitus (FBS ≥ 126 mg /dl) including those on medication was 3.2% (3.5% males and 3.0% females). The prevalence of impaired fasting glucose was 9.1% with ADA criteria and 3.8% with WHO criteria. Hypercholesterolemia was found in 5.2%, hypertriglyceridemia in 21.0%, high LDL cholesterol occurred in 14.1% and low HDL cholesterol occurred in 68.7%. The prevalence of metabolic syndrome using IDF definition was 4.8% (8.6% in females and vs. 1.8% in males). Advanced age, urban residence, lack of physical exercise, raised waist circumference, raised waist hip ratio, overweight or obesity, and total blood cholesterol were significantly associated with raised blood pressure (BP) and diabetes mellitus. Increased waist- hip ratio was an independent predictor of raised blood pressure, hyperglycemia and raised total cholesterol. Our study showed significantly high prevalence of raised blood pressure, hyperglycemia and dyslipidemia in Ethiopia. Community based interventions are recommended to control these risk factors.

ObjectivesThis study examined the association between sexual and reproductive health (SRH) education in peer-group discussion and comprehensive knowledge of HIV among young adolescent girls in rural ...eastern Ethiopia.DesignThe study analysed data from a large quasi-experimental study involving 3290 young adolescent girls aged 13–17 years. The intervention targeted adolescent girls aged 10–14 years. Data were collected using a comprehensive HIV knowledge tool adopted from the demographic and health survey questionnaire. Multi-level mixed-effect logistic regression analysis was employed to examine associations using STATA/SE V.14 statistical software.SettingWest Hararghe, rural Ethiopia.Participants3290 adolescent girls.ResultsMagnitude of comprehensive knowledge of HIV among those who received SRH education and those who did not receive SRH education was 16.78% (95% CI 14.41% to 19.45%) and 14.01% (95% CI 12.38% to 15.81%), respectively. Overall, 14.84% (95% CI 13.4.% to 16.39%) of the adolescent girls aged 13–17 years had comprehensive knowledge of HIV. The odds of having comprehensive HIV knowledge were higher (1.36 times) among adolescent girls who received SRH education compared with those who did not receive SRH education (adjusted OR 1.36, 95% CI 1.01 to 1.84) after controlling for selected potential confounders. Odds of having comprehensive HIV knowledge were also higher (1.73 times) among older adolescent girls (adjusted OR 1.733 95% CI 1.098 to 2.735) and (3.89 times) among those who attended secondary school (adjusted OR=3.889 95% CI 1.836 to 8.235) compared with young adolescent girls and the uneducated, respectively.ConclusionsComprehensive knowledge of HIV among young adolescent girls was very low. Providing SRH education for young adolescent girls improved their comprehensive knowledge of HIV in rural eastern Ethiopia. Initiating sexual education at an early age would benefit HIV prevention efforts.
Stroke is a leading cause of adult disability and death worldwide. Serum lipid levels have established effects on short-term stroke mortality. To reduce the incidence of stroke and stroke-related ...mortality, it is important to assess lipid levels in subtypes of strokes. Hence, the main aim of this study was to assess lipid profile and associated factors among stroke patients.
A comparative cross-sectional study was conducted by recruiting 278 (139 stroke patients and 139 controls) study participants selected by convenient sampling technique from March to July 2021. Socio-demographic, behavioral, and clinical data were collected using a semi-structured questionnaire. Ethical approval was obtained from University of Gondar. After obtaining informed consent, about 5 ml of venous blood was collected to perform lipid profile using DIRUI CS-T240 automated clinical chemistry analyzer. Independent t-test, Mann–Whitney U test, Kruskal-Wallis H test, correlation tests, and logistic regression were used during data analysis. A p-value of <0.05 was considered statistically significant.
The current study found that total cholesterol (170.24 ± 44.66) and low-density lipoprotein cholesterol (114.07 ± 35.82) were significantly higher in stroke patients than in the control group (155.22 ± 18.09) and (103.14 ± 15.65), respectively (P < 0.05). On the other hand, triglycerides (127 (104–141)) and high-density lipoprotein cholesterol (52 (48–57)) were significantly lower in stroke patients than in the control group (127 (104–141)) and (52 (48–57)), respectively (P < 0.05). Additionally, patients with ischemic stroke had significantly higher serum low-density lipoprotein than hemorrhagic stroke patients and controls (P < 0.05). Likewise, patients with hemorrhagic stroke had significantly lowered serum triglyceride levels than ischemic stroke patients and controls (P < 0.05). Dyslipidemia was found in 51.1% of stroke patients. Active smokers (AOR = 6.54, 95% CI = 1.56–27.33), being female (AOR = 3.64, 95% CI = 1.49–8.88), current alcohol drinkers (AOR = 3.51, 95% CI = 1.01–12.25), being diabetes patients (AOR = 3.65, 95% CI = 1.14–11.60) and high body max index (AOR = 4.07, 95% CI = 1.50–11.05) were significantly associated with dyslipidemia.
The overall dyslipidemia and lipid fraction abnormalities were higher in stroke patients. Efforts should be focused towards addressing these lipid abnormalities through lifestyle modification, health education and lipid reduction therapies in order to reduce their adverse effects.
Tuberculosis and diabetes mellitus are significant global public health challenges. In Sub-Saharan Africa, study findings regarding prevalence of diabetes mellitus amongst tuberculosis patients have ...been inconsistent and highly variable. Therefore, this systematic review and meta-analysis estimates the overall prevalence of diabetes mellitus among tuberculosis patients in Sub-Saharan Africa.
Four international databases (PubMed, Google Scholar, Science Direct and Cochrane Library) were systematically searched. We included all observational studies reporting the prevalence of DM among TB patients in Sub-Saharan Africa. All necessary data for this review were extracted using a standardized data extraction format by two authors (CT and AA1). STATA Version 14 statistical software was employed to conduct meta-analysis. The Cochrane Q test statistics and I
test were used to assess the heterogeneity of the studies. Finally, a random effects meta-analysis model was computed to estimate the pooled prevalence of diabetes mellitus in TB patients. Besides, subgroup analysis was done based on different factors.
In the meta-analysis, sixteen studies fulfilled the inclusion criteria and were included. The findings of these 16 studies revealed that the pooled prevalence of diabetes mellitus among tuberculosis patients in Sub-Saharan Africa was 9.0% (95% CI: 6.0, 12.0%). The highest prevalence of diabetes mellitus among tuberculosis patients was found in Nigeria (15%), followed by Tanzania (11%), and then Ethiopia (10%). Besides, the prevalence of diabetes mellitus among HIV infected TB patients was (8.9%) which is slightly higher than HIV uninfected (7.7%) TB patients.
Diabetes mellitus among tuberculosis patients in Sub-Saharan Africa was significantly high. Moreover, this study found that there was a high prevalence of DM among HIV infected than uninfected TB patients. It is strongly recommended to screen for DM among TB patients and special emphasis should be given for early screening of DM among TB/HIV co-infected patients.

Increasing poultry product consumption trends have attracted researchers and development practitioners to look for interventions that transform the low-input low-output-based village chicken ...production to a high yielding production system. However, due to the intricate nature of the production system, there is a dearth of evidence that helps design comprehensive interventions at the smallholder level. Using national-level representative data collected from 3555 village chicken producers in Ethiopia, Nigeria, and Tanzania, this study examines the technical efficiency of village chicken production and investigates the main factors that explain the level of inefficiency. We applied a stochastic frontier analysis to simultaneously quantify the level of technical efficiency and identify factors associated with heterogeneity in inefficiency. We found that the level of technical efficiency is extremely low in the three countries, suggesting enormous opportunities to enhance productivity using available resources. The heterogeneity in technical efficiency is strongly associated with producers’ experience in breed improvements and flock management, limited technical knowledge and skills, limited access to institutions and markets, smaller flock size, gender disparities, and household livelihood orientation. We argue the need to adopt an integrated approach to enhance village producers’ productivity and transform the traditional subsistence-based production system into a commercially oriented semi-intensive production system.
IntroductionPeople having close contact with drug-resistant tuberculosis (DR-TB) patients are at increased risk of contracting and developing the disease. However, no comprehensive review has been ...undertaken to estimate the burden of DR-TB among contacts of DR-TB patients. Therefore, the current systematic review will quantify the prevalence and incidence of DR-TB among contacts of DR-TB patients.Method and analysisSystematic searches will be conducted in Medline, Embase, Web of Science, Scopus, Cochrane Central Register of Controlled trials (CENTRAL) and Cumulative Index to Nursing and Allied Health Literature (CINHAL) databases. The search will be conducted without restrictions on time, language and geography. A random-effects meta-analysis will be conducted for effect estimates. The pooled prevalence and incidence of DR-TB will be compared between people with and without contact with DR-TB patients. The presence of heterogeneity between studies will be assessed by Higgins I2 statistics. Subgroup analysis will be conducted to determine the source of heterogeneity. The risk of bias will be assessed using a visual inspection of the funnel plot and Egger’s regression test statistics. Trim and fill analysis will be done in the presence of publication bias. A sensitivity analysis will be conducted by trimming low-quality studies. The systematic review will be reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol guidelines.Ethics and disseminationEthical approval will not be required for this study as it will be a systematic review and meta-analysis based on previously published evidence. The findings of the systematic review will be presented at scientific conferences and published in scientific journals.Protocol registrationThe protocol is published in PROSPERO with registration number CRD42023390339.
This study investigates the relationship between adolescent girls' agency and social norms regarding early marriage, girls' education, and nutrition in West Hararghe, Ethiopia.
We conducted a ...cross-sectional study involving adolescent girls aged between 13 and 17 years in 2016. A two-stage cluster sampling procedure was followed to identify eligible respondents at the household level. A total of 114 clusters in four districts and 30 households from each cluster were randomly selected. Data were collected using a structured and pretested questionnaire. The agency composite score was measured based on 21 previously validated items. Descriptive and injunctive norm composite scores regarding education, marriage, and nutrition were constructed based on context-relevant items. The weighted mean and standard errors were calculated for the agency and social norms composite scores. The relationship between girls' agency and descriptive and injunctive norms were examined using a multivariable linear regression model that accounted for a complex sample survey design.
A total of 3,186 adolescent girls participated in this study. The multivariable linear regression analysis revealed that adolescent girls' agency score significantly and favorably associated with education (β = .19, p < .001), marriage (β = .13, p < .01), and nutrition (β = .20, p < .01) descriptive norms after adjusting for individual and household characteristics. Similarly, adolescent girls' agency was significantly and favorably associated with marriage (β = .21, p < .001) injunctive norms; however, positive injunctive norms around education (β = .09, p > .05) and nutrition (β = .12, p > .05) did not have a statistically significant association with girls' agency. The domains of agency scale related to the belief in women's health rights related to contraception use and the belief in women's right to refuse sex showed poor prosocial views.
Favorable descriptive and injunctive norms around marriage were significantly associated with greater adolescent girls' agency, which indicates the need to incorporate interventions that address social norms in efforts aimed to enhance adolescent girls' sexual and reproductive health status. Furthermore, attention should be given to monitor which domain of agency is improved by the interventions.
