Environmental Impact Study of Cement Factory using a Multi-Criteria Analysis: Evidence from Messebo Cement Factory, Ethiopia

Cement is a pillar to develop infrastructures in Ethiopia. At the same time, cement production affects the local environment and nearby communities. Therefore, this paper aims to analyse the local environmental impacts of the Messebo Cement Factory in Tigray, Northern Ethiopia, and to identify the consequences of these impacts. A multi-criteria analysis and community perception survey were used. Primary data were collected through key informant interviews with three purposefully selected management bodies to identify the main impacts. A structured questionnaire on ten purposively selected external experts helped to estimate the weighting factors. Moreover, sixty employees, who were selected through clustered random sampling for scoring the identified impacts, and 120 randomly selected households, were investigated for the perception survey analysis. Moreover, the study used secondary data from supplementary documents to complement the primary data. The study shows that the preparation of raw material and coal, and clinker production at the factory are the major sources of environmental impacts. Additionally, most environmental impacts of the activities in the crushing and raw milling and coal and kiln processing units are substantial and affect the surrounding communities and local environment. The local communities suffer most from the dust particles of processing materials, noise, odour, heat lost and storm water. The study recommends that the factory introduce impact reduction and prevention programs. Such programs will improve the environmental quality of the surroundings and safeguard local inhabitants.

Dietary Diversity Practice and Associated Factors Among Infants and Young Children in Haramaya Town, Ethiopia

Optimum child feeding is crucial for growth, development, and better health in later life. Dietary diversity is a critical part of the feeding practices. However, there is limited evidence on dietary diversity practice in low-income countries, like Ethiopia. This study assessed dietary diversity practice and associated factors among mothers of infants and young children aged 6-23 months in Haramaya Town, Eastern Ethiopia. Community based cross-sectional study design was used and study participants were selected by simple random sampling. Data were collected using a pre-tested questionnaire by face-to-face interview. The collected data were entered to EpiData version 3.1 and exported to SPSS version 22.0 for analysis. Characteristics of the study participants were described by using frequencies, percentages, summary measures, and tables. Bi-variable and multi-variable analyses were used to identify the associated factors. Statistical significance was declared at p-value < 0.05. The study included 635 participants yielding to a response rate of 98.1%. The prevalence of dietary diversity practice was 25.2%. Mothers learned up to secondary level or above [(AOR=2.97, 95% CI: (1.26, 6.99)], mothers who had job [(AOR=3.21, 95% CI: (1.41, 7.29)], older children [(AOR=2.51, 95% CI: (1.45, 4.34)], male children [(AOR= 2.08, 95% CI: (1.29, 3.33)], healthy children [(AOR=2.65, 95% CI: 1.36, 5.16)] and richest households [(AOR=4.45, 95% CI: 1.94, 10.22)] were associated with dietary diversity practice. Generally, the dietary diversity practice was low. Therefore, attention should be given to mothers with no formal education and efforts should be done to improve the socioeconomic status of the households

BLOOD PRESSURE DISTRIBUTION AND HYPERTENSION IN TWO RURAL COMMUNITIES OF GONDAR REGION, ETHIOPIA

ABSTRACT: The purpose of this study was to document the distribution of blood pressures and the prevalence of hypertension in two rural communities located in the northwestern Gondar Region of Ethiopia. Based upon a systematic random sampling, 226 households (724 persons) were selected. Mean systolic and diastolic blood pressures (SBP and DBP) were calculated separately for male and female children (5 -15 years) and adults. Among male and female children the mean SBP's were 110.0 +/- 9.5 and 113.4 =/- 10.0, while the mean DBP's were 73.8 +/- 8.2 and 73.8 +/- 7.9, respectively. The difference in mean SBP's was statistically significant (p<0.05). Among adult males and females the mean SBP was 118 +/- 13.3 and 114.0 +/- 14.5, while the mean DDP was 73.5 +/- 8.2 and 72.7 +/- 9.2 respectively. The difference in mean SBP's was statistically significant (p<0.05). Blood pressure was found to rise with age. The prevalence of hypertension in children was 4.3% and in adults 2.7%. Prevalence rates were not significantly different in females and males

Isolation and Antimicrobial Sensitivity Testing of Escherichia coli from Fish Meat Retailing Shops of Mekelle City, Ethiopia

The present study was conducted for the period of six months, September, 2016 to February, 2017 so as to isolate and identify Escherichia (E.coli) from fresh fish samples collected from four different retailing shops in Mekelle city and determine the antibiotic resistance pattern of isolated bacteria. Isolation and identification of E.coli and antibiotic sensitivity test were performed following the standard microbiological techniques. The antibiotic resistance patterns of the E.coli isolates were tested against 6 different antibiotics, namely Ampicillin, Amoxicillin, Ciprofloxacin, Norfloxacin, Gentamicin and Streptomycin. Accordingly, out of the total 96 fish samples collected and analyzed, 9(9.4%) were positive for E.coli following the primary and secondary biochemical test results. Out of the four fish meat retailing shops, the highest and statistically significant prevalence (P=0.001) of E.coli was recorded in shop III as 5(20.8%) followed by shop II as 4(16.7%).Furthermore, results of the antimicrobial sensitivity test have shown that all of the isolates were completely significantly (P=0.001) resistant to two antibiotics (Ampicillin and Amoxicillin) and 100% significantly susceptible (P=0.001) to three of the antibiotics (Ciprofloxacin, Norfloxacin, and Gentamicin). Whereas, out of the 9 isolates, 2 isolates (22.2%) were intermediate and 7 isolates (77.8%) were susceptible to Streptomycin. Hence, it can be concluded that fishes from Mekelle shops do contain antimicrobial resistant pathogenic E.coli where the proportion of these isolates significantly (P<0.001) varies from shop to shop. In spite of the lesser practice of their utilization, Ciprofloxacin, Norfloxacin, and Gentamicin were found to be the best antimicrobials to treat E.coli associated infections in the study area. However, it is suggested that post-harvest hygienic management practices are to be practiced along the fish production-marketing chain.Antibiotic sensitivity test, Escherichia coli, Fish, Mekelle, Retailing shops

Genetic diversity in tef [Eragrostis tef (Zucc.) Trotter]

Tef [Eragrostis tef (Zucc.) Trotter] is a cereal crop resilient to adverse climatic and soil conditions, and possessing desirable storage properties. Although tef provides high quality food and grows under marginal conditions unsuitable for other cereals, it is considered to be an orphan crop because it has benefited little from genetic improvement. Hence, unlike other cereals such as maize and wheat, the productivity of tef is extremely low. In spite of the low productivity, tef is widely cultivated by over six million small-scale farmers in Ethiopia where it is annually grown on more than three million hectares of land, accounting for over 30% of the total cereal acreage. Tef, a tetraploid with 40 chromosomes (2n = 4x = 40), belongs to the family Poaceae and, together with finger millet (Eleusine coracana Gaerth.), to the subfamily Chloridoideae. It was originated and domesticated in Ethiopia. There are about 350 Eragrostis species of which E. tef is the only species cultivated for human consumption. At the present time, the gene bank in Ethiopia holds over five thousand tef accessions collected from geographical regions diverse in terms of climate and elevation. These germplasm accessions appear to have huge variability with regard to key agronomic and nutritional traits. In order to properly utilize the variability in developing new tef cultivars, various techniques have been implemented to catalog the extent and unravel the patterns of genetic diversity. In this review, we show some recent initiatives investigating the diversity of tef using genomics, transcriptomics and proteomics and discuss the prospect of these efforts in providing molecular resources that can aid modern tef breeding

Outbreak investigation of foot-and-mouth disease in cattle in Tigray region, Northern Ethiopia.

An investigation of a foot-and-mouth disease (FMD) outbreak was conducted between late October and mid-December 2019 in Tigray region. The outbreak investigation team collected epidemiological data from the six villages of Kafta Humera and Seharti Samre districts, including morbidity proportions, mortality proportions, and clinical signs, and cattle management and vaccination history were collected via participatory methods, including interviews and group discussions with local experts and farmers in Kafta Humera and reports from the district veterinarians in Seharti Samre. Twenty-two tissue samples were collected for laboratory confirmation. Overall, 4,299/9,811 (43.8%) and 13,654/16,921 (80.6%) cattle showed clinical signs for FMD in Kafta Humera and Seharti Samre, respectively. In Kafta Humera, the highest morbidity proportion was found in adult cows and heifers (48.1%), followed by 27.8% in oxen and 15.9% in calves. In Seharti Samre, the morbidity proportion was similar in all age groups at ~81%. No death of FMD-suspected cattle was reported throughout the outbreak. The serotype of foot-and-mouth disease virus (FMDV) identified by laboratory analysis differed between the two districts (serotype O in Kafta Humera and serotype A in Seharti Samre). We, therefore, suggest that the outbreaks in the two districts occurred independently from each other. Experts and farmers were interviewed and believed that the outbreak in Kafta Humera was most likely caused by interaction between cattle and wildlife from the surrounding Kafta Sheraro National Park, which share common grazing land. This outbreak investigation showed that FMD can cause devastating cattle morbidity. A regular vaccination program against the identified circulating FMDV serotypes with sufficient coverage is required to avoid future outbreaks

Prevalence and associated factors of structural congenital anomalies in resource limited setting, 2023: a systematic review and meta-analysis

BackgroundSeveral studies have been conducted on structural congenital anomalies (CA). However, there is a paucity of studies that provide a comprehensive review of structural anomalies. We aimed to verify the available research articles to pool the possible risk factors of structural CA in resource-limited settings.SettingThe research articles were genuinely searched using PubMed, Scopus, Cochrane Library, Web of Science, free Google database search engines, Google Scholar, and ScienceDirect databases. Published studies were searched and screened for inclusion in the final analysis, and studies without sound methodologies and review and meta-analysis were not included in the analysis.ParticipantsThis review analyzed data from 95,755 women who gave birth as reported by primary studies. Ten articles were included in this systematic review and meta-analysis. The articles that had incomplete information and case reports were excluded from the study.ResultsThe overall pooled effect estimate (EI) of structural CA was 5.50 (4.88–6.12) per 100 births. In this systematic review and meta-analysis, maternal illness EI with odds ratio (OR) = 4.93 (95% CI: 1.02–8.85), unidentified drug use with OR = 2.83 (95% CI: 1.19–4.46), birth weight with OR = 4.20 (95% CI: 2.12–6.28), chewing chat with OR = 3.73 (95% CI: 1.20–6.30), chemical exposure with OR = 4.27 (95% CI: 1.19–8.44), and taking folic acid tablet during pregnancy with OR = 6.01 (95% CI: 2.87–14.89) were statistically significant in this meta-regression.ConclusionsThe overall pooled effect estimate of structural CA in a resource-limited setting was high compared to that in countries with better resources. Maternal illness, unidentified drug use, birth weight, chewing chat, chemical exposure, and never using folic acid were found to be statistically significant variables in the meta-regression. Preconception care and adequate intake of folic acid before and during early pregnancy should be advised.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier CRD42022384838

Interpreting ambiguous ‘trace’ results in Schistosoma mansoni CCA Tests: Estimating sensitivity and specificity of ambiguous results with no gold standard

Background The development of new diagnostics is an important tool in the fight against disease. Latent Class Analysis (LCA) is used to estimate the sensitivity and specificity of tests in the absence of a gold standard. The main field diagnostic for Schistosoma mansoni infection, Kato-Katz (KK), is not very sensitive at low infection intensities. A point-of-care circulating cathodic antigen (CCA) test has been shown to be more sensitive than KK. However, CCA can return an ambiguous ‘trace’ result between ‘positive’ and ‘negative’, and much debate has focused on interpretation of traces results. Methodology/Principle findings We show how LCA can be extended to include ambiguous trace results and analyse S. mansoni studies from both Côte d’Ivoire (CdI) and Uganda. We compare the diagnostic performance of KK and CCA and the observed results by each test to the estimated infection prevalence in the population. Prevalence by KK was higher in CdI (13.4%) than in Uganda (6.1%), but prevalence by CCA was similar between countries, both when trace was assumed to be negative (CCAtn: 11.7% in CdI and 9.7% in Uganda) and positive (CCAtp: 20.1% in CdI and 22.5% in Uganda). The estimated sensitivity of CCA was more consistent between countries than the estimated sensitivity of KK, and estimated infection prevalence did not significantly differ between CdI (20.5%) and Uganda (19.1%). The prevalence by CCA with trace as positive did not differ significantly from estimates of infection prevalence in either country, whereas both KK and CCA with trace as negative significantly underestimated infection prevalence in both countries. Conclusions Incorporation of ambiguous results into an LCA enables the effect of different treatment thresholds to be directly assessed and is applicable in many fields. Our results showed that CCA with trace as positive most accurately estimated infection prevalence
