Abstract: After cellulose, chitin is the most widespread biopolymer available in nature. Chitin has economic value because of its biological activities, industrial and biomedical applications. There are three sources of chitin, namely crustaceans, insects and microorganism. The commercial sources of chitin are shells of crustaceans such as shrimp, crabs, lobsters and krill. In the present study, chitin has been extracted from locally available fish in Rourkela. The obtained chitin was converted into the more useful chitosan. The obtained chitin and chitosan have been characterized by using different techniques like spectral analysis, X-ray diffraction, Elemental analysis, Fourier transforms infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Differential scanning calorimetry (DSC). XRD analysis indicated the crystalline nature of the chitin and chitosan. The FTIR patterns displayed the bands corresponding to stretching and vibration of O-H, N-H and CO bonds and conformed the formation of α -chitin. Degree of deacetylation (DD) value was calculated using elemental analysis, potentiometric titration and FTIR. Using FTIR analysis DD value was found to be 61%.

Abstract: Groundwater is main sources of water supply in Modjo River Basin. In this study, 31 groundwater samples were collected and analyzed to determine suitability of groundwater for drinking and irrigation uses. Spatial variation map of major cations (Ca2+, Mg2+, Na+, K +) and anions (HCO3−, NO3−, SO42−, F−, Cl−) were produced using IDW interpolation in GIS. Piper pilot show that, Ca–Na–HCO3, Na–Ca–HCO3 (mixed) and Na–HCO3 water types are found in study area. Ca2+ and Mg2+ are dominant in highland aquifer whereas Na+ is dominant in rift valley aquifer. HCO3− is the dominant anion in all samples. Rock-water interaction and cation exchange along groundwater flow path are responsible for the current characteristics of hydrogeochemical facies. Water quality index using quality rating scale to evaluate the suitability of water for drinking purpose shows that 3.23% and 93.54% of groundwater samples fall within excellent and good water quality, respectively. On the other hand 3.23% of groundwater samples fall within poor water quality. From the computation of SAR values it was found that 97% of groundwater samples are in suitable class and the remaining 3% constituting doubtful class for irrigation use. RSC value shows that, 9.67% of groundwater samples fall in good categories for irrigation use. Whereas, 41.93% samples falls in doubtful and 48.38% samples falls in unsuitable categories for irrigation use. In general, geogenic process and anthropogenic activities such as urban sewages and fertilizers are factors governing groundwater chemistry of study area.

TL;DR: The high prevalence of anaemia indicates it is currently a serious health problem of pregnant women living in Gilgel Gibe Dam area and there is a need to design strategies that help to diagnose pregnant women for malaria and STH infections during their antenatal care (ANC) visit.
Abstract: Anaemia is known to be one of the outcomes of parasitic infection and it may result in impaired cognitive development, reduced physical work capacity and in severe cases increased risk of mortality, particularly during the prenatal period. The aim of this study was to determine the prevalence and associated risk factors of anaemia among pregnant women in Gilgel-Gibe dam area, southwestern Ethiopia. A cross-sectional community based study was conducted on 388 pregnant women living in three districts around Gilgel Gibe Dam area, southwestern Ethiopia. Socio-demographic and socio-economic data were collected from each participant. A single stool sample was also collected from each selected pregnant woman. Haemoglobin concentration was determined by the cyanmethemoglobin method. Plasmodium infection prevalence and intensity were assessed with thin and thick blood film examination. Of the total 388 study participants, 209 (53.9%) were anaemic. Pregnant woman who were rural residents (Adjusted odds ratio (AOR) = 1.62, 95% C.I: 1.02-2.62, P= 0.042), not using insecticide treated nets (ITNs) during the study period (AOR = 2.84, 95% C.I: 1.33-6.05, p = 0.007), those who were Plasmodium malaria infected (AOR = 11.19, 95% C.I: 3.31-37.7, p= 0.01) and those with Soil Transmitted Helminth (STH) infections (AOR=1.82, 95% C.I: 1.16-2.87, p=0.001) had higher odds of being anaemic than those who were urban residents, using ITNs, free of Plasmodium malaria and Soil transmitted helminth infection, respectively. There was a significant correlation between increasing hookworm parasite load (r = −.110, P< 0.001), Ascaris lumbricoides (r = −.122, P < 0.001) and Trichuris trichiura(r = −.025, P < 0.001) and decreasing hematocrit values. The high prevalence of anaemia indicates it is currently a serious health problem of pregnant women living in Gilgel Gibe Dam area. Plasmodium malaria and soil transmitted helminth infections were significantly associated with anaemia. Antenatal care should promote de-worming and education on personal hygiene. Therefore, there is a need to design strategies that help to diagnose pregnant women for malaria and STH infections during their antenatal care (ANC) visit instead of testing for only haemoglobin (Hgb) levels and blood group.

TL;DR: Patients who were not in strict DOTS programs and did not adhere to first- line TB treatment and patients who experienced side effects during first-line treatment and Category II retreatment were at significantly increased risk of developing MDR-TB.
Abstract: Background Worldwide, there were 650,000 multidrug-resistant tuberculosis (MDR-TB) cases in 2010, and in 2008 the World Health Organization estimated that 150,000 deaths occurred annually due to MDR-TB. Ethiopia is 15th among the 27 MDR-TB high-burden countries. This study identifies factors associated with the occurrence of MDR-TB in patients who underwent first-line TB treatment in Addis Ababa City.

TL;DR: Age, sex, type of diabetes mellitus and duration of diabetes were significantly associated with the development of diabetic complications and increased occurrence of retinopathy, peripheral neuropathy, hypertension and nephropathy was observed with longer duration of illness.
Abstract: Background: Diabetes Mellitus is common metabolic disease worldwide. Its complications in the Ethiopian care setup has not been well documented. The objective of this study was to assess the pattern and distribution of dia-betic complications among patients having follow-up at Jimma University specialized Hospital diabetic clinic. Methods: A cross sectional study based on record review of 305 patients, selected using systematic sampling with replacement was carried out in October 2008. The data were analyzed using SPSS for Windows version 13.0. Results: Larger proportion, 189 (62.0%), of patients had type II diabetes and 163 (53.4%) of them were diabetic for less than 5 years. Seventy three of the 76 (96.1%) patients with type II diabetes mellitus had hypertension. Acute complications were observed in 93 (30.5%) of the patients of which Diabetic Ketoacidosis was documented in 66(71.0%). Forty eight (45.7%) of patients had proteinuria, 90 (29.5%) had peripheral neuropathy, 13(6.8%) had impotence. Diabetic foot ulcer, skin and/or subcutaneous tissue infection, dental problems and tuberculosis were documented in 14(4.5%), 31(10.0%), 31(10.0%), and 17(5.6%) patients, respectively. Any of the chronic complications were not different by sex of the patient but age had statistically significant association with hypertension, visual distur-bance and neuropathy (p< 0.05). Type of diabetes had statistically significant association with all the tested com-plications except infection (P<0.05) where most of the complications occurred in type II diabetics. Statistically significant association was observed between the duration of the diabetes and impotence and visual disturbances (p < 0.05). Conclusion: The majority of patients were type II diabetics. Acute complications were observed more commonly among type I diabetics and DKA was the commonest acute complication. The frequency of chronic complications was high. Increased occurrence of retinopathy, peripheral neuropathy, hypertension and nephropathy was ob-served with longer duration of illness. Impotence and diabetic nephropathy were more common in type II diabet-ics. The study showed that age, sex, type of diabetes mellitus and duration of diabetes were significantly associated with the development of diabetic complications.
