Association between Khat Chewing and Gastrointestinal Disorders: A Cross Sectional Study

Background: Khat (Catha edulis Forsk) is a psycho-stimulant substance grown in East Africa. But its adverse effects and its prevalence are not well studied. The main aim of the present study is thus to assess the association between khat chewing and GI problems among students in Ambo University.Methods: A cross-sectional study was conducted in January 2010 on 1005 Ambo University students. Study subjects were selected using systematic random sampling technique, and data were collected using self-administered questionnaire. Data analysis was made using SPSS version 16.0 for windows package.Results: The mean age of the respondents was 20.79 ± 1.39 ranging from 18-30 years. Seven hundred twenty (71.6 %) of the study participants were males and 994 (98.9%) were in the age group of 15- 24 years. The prevalence of gastritis was 580 (57.7%); constipation 235 (23.4%); hemorrhoids 54 (5.4%) and that of dental problems (carries, decay, filling and extraction) was 225 (22.4%) of all study participants. Gastrointestinal disorders were found to be higher among khat chewers, where 64(36.2%) of them had dental problems; 127(71.8%) symptoms of gastritis; 86(48.6%) constipation and 26(14.7%) hemorrhoids which demonstrated statistically significant association with p < 0.001.Conclusions: The prevalence of gastrointestinal disorders was found to be higher among khat chewers, indicating that khat chewing could be a predisposing factor to gastrointestinal disorders. Community-based awareness creation about the adverse effect of khat use is thus recommended.Keywords: Khat chewing, Gastritis, Constipation, Hemorrhoid

Role of maternity waiting homes in the reduction of maternal death and stillbirth in developing countries and its contribution for maternal death reduction in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Every family expect to have a healthy mother and new born baby after pregnancy. Especially for parents, pregnancy is a time of great anticipation. Access to maternal and child health care insures safer pregnancy and its outcome. MWHs is one the strategy. The objective was to synthesize the best available evidence on effectiveness of maternity waiting homes on the reduction of maternal mortality and stillbirth in developing countries. METHODS: Before conducting this review non-occurrences of the same review is verified. To avoid introduction of bias because of errors, two independent reviewers appraised each article. Maternal death and stillbirth were the primary outcomes. Review Manager 5 were used to produce a random-effect meta-analysis. Grade Pro software were used to produce risk of bias summary and summary of findings. RESULT: In developing countries, maternity waiting homes users were 80% less likely to die than non-users (OR = 0. 20, 95% CI [0.08, 0.49]) and there was 73% less occurrence of stillbirth among users (OR = 0.27, 95% CI [0.09, 0.82]). In Ethiopia, there was a 91% reduction of maternal death among maternity waiting homes users unlike non-users (OR = 0.09, 95% CI [0.04, 0.19]) and it contributes to the reduction of 83% stillbirth unlike non-users (OR = 0.17, 95% CI [0.05, 0.58]). CONCLUSION: Maternity waiting home contributes more than 80% to the reduction of maternal death among users in developing countries and Ethiopia. Its contribution for reduction of stillbirth is good. More than 70% of stillbirth is reduced among the users of maternity waiting homes. In Ethiopia maternity waiting homes contributes to the reduction of more than two third of stillbirths

Assessing Soil Nutrient Additions through Different Composting Techniques in Northern Ethiopia

The use of vermi-compost in northern Ethiopia is not a common practice. It is, therefore, important to understand the possible impediments through studying its chemical and biological properties and its extra contribution compared to other composting techniques. Four compost types (vermi-compost, conventional compost, farmers’ compost and community nursery compost) with three replications were used in this study. The farmers’ and community nursery compost samples were collected from different places in Tigray; whereas, the vermi- and conventional composts were prepared at Mekelle University following a standard composting procedure. Six major composting materials were identified in the visited sites from farmers’ and community nursery foremen’s interview. These composting materials were also used for the vermi- and conventional composting. Twelve composite compost samples were taken for analysis of macro- and micro-nutrients. The results of the experiment showed that for all treatments, despite of having high content of total C (5.04 – 10.67%), the C/N ratio (12.19 – 12.22) was low. This suggests that as the C/N ratio is lower than the threshold (< 30), mineralization is faster, nutrients eventually become available and a large amount of N is lost. Soil pH, exchangeable Magnesium (ex.Mg), exchangeable Potassium (ex.P), available Phosphorus (ava.P), and Cation Exchange Capacity (CEC) showed significant differences among the different composting techniques. Among the selected compost types, ex.Mg, ex.Ca and av.P were higher for vermi-compost. The lowest was recorded in community nursery compost. The use of vermi-compost is, therefore, very helpful in terms of providing beneficial soil nutrients as compared to other compost types.Keywords: Conventional compost, Vermi-compost, farmers’ compost, Nursery compost, Macro-nutrients, Micro-nutrients

Management of undescended testes: a retrospective study from a tertiary hospital in Ethiopia

Background: Undescended testis is one of the commonest congenital malformations seen in boys. The aim of this study is to evaluate the pattern of presentation, approach to diagnosis, treatment and follow up in Tikur Anbesa Specialized Hospital, a tertiary teaching hospital in Ethiopia.Methods: This is a retrospective cross sectional study of all boys with undescended testis operated in Tikur Anbesa Specialized Hospital between September 2012 and August 2014.Results: Of 82 boys operated within the study period, 66 boys with 78 undescended testes are studied. Twenty-six percent (17/66)came before the age of 2 years, while the majority of the study group, 50% (33/66), presented beyond 5 years of age. Of the 17 boys brought to the hospital before 2 years, only 41% (7/17) them were treated before the age of two years. The majority 89% (59/66) of the boys were treated after 2 years of age. Seventy-one testes of 78 [91%] were in the inguinal canal, 5 were intra-abdominal and 2 were absent. 46% (36/78) were on the left side, 29% (23/78) on the right side and the rest were bilateral. Among the 54 boys who had ultrasound examination, the ultrasound report is consistent with operative findings in 33 [61%]. Associated congenital malformations were found in 31.8% (21/66) of the boys. Hypospadia was the predominant malformation comprising 38% (8/21) of the total congenital malformations. Orchidopexy was done for 82% (64/78) of the total testes, orchiectomy was done for 9% (7/78) and biopsy was taken in 1 case. Among the total operated boys only 62% (41/66) were followed in our clinic; of those who had follow up 10% (4/41) testes atrophied and 1 [2%] testis retracted.Conclusion: Boys with undescended testes present and are treated late in Tikur Anbesa Hospital. As opposed to the literatures most of the undescended testes were found on the left side. Ultrasound examination cannot be the only mode of examination for undescended testes as it misses more than one third of the cases. Hypospadia is the commonest associated congenital malformation. Post operative follow up is very poor after treatment for undescended teste

Growth and Nutrients Content and Uptake of Garlic (Allium sativum L.) as Influenced by Different Types of Fertilizers and Soils

Farmers strive to produce high yield and good quality garlic both for  consumption and economic value but soil fertility depletion is among the major impediments to sustained garlic production, especially in the less developed countries, because of limited application of suitable rate, type and sources of fertilizers. Thus, the study was conducted on Andosol and Vertisol soils at Debre Zeit Agricultural Research Center, Ethiopia, for two consecutive (dry and main rainy) seasons to assess the effect of various rates of compound fertilizers on growth, and nutrient content and uptake  of garlic. The treatments consisted of control (unfertilized), one level of recommended NP (92/40 kg ha-1), three levels of Azofertil (100, 200, 300 kg ha-1), four levels of Basic (100, 200, 400, 600 kg ha-1) and three levels of D-coder (100, 200, 400 kg ha-1). The experiment was laid out as a randomized complete block design with three replications at each site. The morphological characters like plant height, neck thickness and leaf  area index of garlic at different growth stages, and the contents and uptake of nutrients like nitrogen, phosphorus, potassium and sulphur of the crop were significantly increased due to the applications of higher levels of Azofertil, Basic and D-coder compound fertilizers on Andosol soil during both seasons. However, the lowest growths, and nutrients content and uptake were recorded from the garlic plants fertilized with lower levels of the three compound fertilizers, recommended NP and the control plot, especially on Vertisol. Generally, plant growths, and nutrients contentsand uptake of garlic followed by Azofertil at the rate of 300 kg ha-1 on Andosol during dry season by irrigation

Outcome of preterm twins compared to preterm singleton neonates, a multicenter prospective observational study in Ethiopia

Background: In recent decades there has been a major increase in multiple birth rates, and the rate of twining vary from 6-9 per thousand life births to 20 per thousand live births across differ-ent areas of the world. Many studies have demonstrated higher neonatal and perinatal mortality and morbidity rates in twin deliveries compared to singleton births. This study was aimed to com-pare the outcomes of preterm twins and preterm singletons.Methods: A prospective, observational multicenter study was conducted from July 2016 to May 2018 in five tertiary hospitals in Ethiopia. All preterm, liveborn infants born at or transferred at less than 7 days of life to one of the study hospitals with an estimated gestational age below 37 weeks were included.Results: A total of 3,703 preterm neonates admitted to participating neonatal intensive care units were included in the study, of which 1171(31.6%) were twins. After adjusting for birth weight and gestational age, the mortality rate for preterm singletons of 31.0% was higher than the mortality rate for preterm twins of 24.8%, which was statistically significant (p-value = 0.001), OR of 1.37 (95% CI: 1.15 to 1.64). The study also identified an inverse relationship between birth weight and gestational age, and mortality. Male singletons were more likely to die than male twins (440 (32.4%) vs. 141 (23.4%); AOR 1.56 (95% CI: 1.22, 1.99); p=0.001)Conclusion: Our study showed that the mortality of a singleton preterm infant was significantly higher than the mortality of a preterm twin infan
