BackgroundAnemia is a common problem in diabetic patients. Diabetic patients have a greater severity of anemia as the level of Glomerular Filtration Rate (GFR) decreases compared to non-diabetic patients. Despite these facts, anemia is unrecognized and largely untreated in patients with diabetes in Ethiopia particularly in those patients attending Fenote Selam Hospital. Therefore, this study was aimed to assess the association of anemia and renal function test among diabetes mellitus patients attending Fenote Selam Hospital, North West of Ethiopia.MethodsAn Institutional -based cross-sectional study was conducted from February 2012 to April 2012 on diabetes mellitus (DM) patients. Systematic random sampling technique was used to get the total sample size of 384 patients. A total of seven ml of venous blood was collected from diabetes mellitus patients; two ml was collected by EDTA anticoagualted vacutainer test tube for haemoglobin determination and 5 ml venous blood was collected by plain vacutainer tube for creatinine and Blood urea nitrogen determination. The data were double entered and analyzed using SPSS-16 statistical software. The degree of association between independent and dependent variables was assessed using bivariate and multivariate logistic regression analysis in terms of P-value and odds ratio with 95% confidence interval.ResultsOut of the total 384 DM patients included in the study 73 (19%) were anemic. Fifty three (13.8%), forty eight (12.5%), and two hundred eighty three (73.7%) DM patients had an estimated GFR <60 ml/min/1.73 m, 60 – 90 ml/min/ 1.73 m, and > 90 ml/min/1.73 m respectively. One hundred eleven (28.9%) diabetic patients had increased urine albumin level. There was a statistically significant association between anaemia and Glomerular filtration rate (P<0.05) with Odds ratio of 8.58 and CI (10.21, 49.94). As the glomerular filtration rate increase, the risk to be anemic will decrease dramatically.ConclusionThe study showed that there was a significant association between anaemia and Glomerular filtration rate in DM patients. Therefore, DM patients should be strictly monitored for renal failure and anemia for proper management of diabetes patients.

Summaryobjective To assess the susceptibility ⁄ resistance level of Anopheles gambiae s.l. to DDT, malathion, permethrin and deltamethrin in different parts of Ethiopia.methods Field collected female An.gambiae s.l. was exposed for 1 h to discriminating dosage of 4% DDT, 5% malathion, 0.75% permethrin and 0.05% deltamethrin using WHO insecticide susceptibility test kits and procedures. Knockdown and mortality rates were recorded at 10, 15, 20, 30, 40, 50 and 60 min and 24 h post-exposure respectively.results Anopheles gambiae s.l. was sensitive to DDT only in 2 of 16 localities where susceptibility studies were carried out in northern Ethiopia; it was resistant in 11 sites and potentially resistant in three. To malathion, the test population was sensitive in four of the six study sites in southern Ethiopia and potentially resistant in the other two sites. In northern Ethiopia, the population was resistant in five localities and sensitive in three. Of the six localities in northern Ethiopia where permethrin was tested, populations were sensitive in three, resistant in one and potentially resistant in two. In southern Ethiopia, the populations were resistant in five of the six sites. Against deltamethrin, the population was sensitive in five of 13 localities, three in northern and two in southern Ethiopia. It was resistant only in two localities, one in northern and one in southern Ethiopia, and potentially resistant in five localities. In eastern Ethiopia at Sabure, the population was sensitive to all insecticides but DDT to which it was potentially resistant. conclusion The existence of high level of DDT and pyrethroid resistance with the possibility of crossresistance to each other and other classes of agricultural pesticides could seriously jeopardise the efficacy of both ITNs and IRS in the country in the future. Insecticide resistance monitoring and surveillance systems as part of a malaria control programme are mandatory for proper management of resistance. The use of a mixture of unrelated insecticides for impregnating nets and rotational use of insecticides for IRS is suggested as a way forward.

Background The prevalence of diabetes mellitus (DM) is increasing globally and its comorbidity with tuberculosis (TB) is re-emerging, especially in low- and middle-income countries. Objective The main aim of this study is to determine the prevalence of DM and HIV infection and their associated risk factors among active tuberculosis patients in Northwest Ethiopia. Methods This hospital-based cross-sectional study was conducted between February 1st and June 30th, 2017 among active TB patients in two hospitals of Northwest Ethiopia. Two hundred and sixty-seven active TB cases aged 18 years or older were screened for diabetes using fasting blood glucose (FBG) test. Semi-structured questionnaires were used to collect demographic data, lifestyle habits and clinical data. Identification of pre-diabetes or diabetes in TB patients was achieved according to American Diabetes Association guidelines (2016). Results Prevalence of DM and TB comorbidity was 11.5% (95% confidence interval, CI 7.8–15.2) compared to 24.9% (95% CI 20.1–30.1) for pre-diabetes. Prevalence of HIV/TB co-infection was 21.9% (95% CI 16.7–26.8). Risk of DM was higher in TB patients from a rural location (adjusted odds ratio, aOR 3.13, 95% CI 1.02–9.62, p = 0.046). Similarly, DM was higher in TB patients who have a family history of DM (aOR 4.54, 95% CI 1.31–15.68, p = 0.017). Furthermore, HIV/TB co-infection was identified as a predictor of DM comorbidity in active TB patients (aOR 5.11, 95% CI 2.01–12.98, p = 0.001). Conclusion The magnitude of DM and pre-diabetes in active TB patients in Northwest Ethiopia was high, warranting collaborative efforts to improve screening and adopt better clinical management strategies for DM–TB comorbid patients. Furthermore, being rural residents, family history of DM and HIV/TB co-infection were found to associate with DM among TB patients, highlighting the importance of the above-mentioned risk factors in the clinical management of this comorbidity.

Long term and wide use of indoor residual sprays augments the selection of insecticide resistance genes. The development of insecticide resistance in an insect population depends up on the volume and frequency of sprays against them and the inherent characteristics of the insect species. However, despite its use for decades, the effect of residual sprays on the status of insecticide resistance of malaria vectors is unknown in Ethiopia. The objective of this study was to assess the effect of bendiocarb 80% WP indoor residual spraying on insecticide resistance status of An. arabiensis in Bahir Dar Zuria District, Northwest Ethiopia. Susceptibility of An. arabiensis was examined against different insecticides using 2-3-day old female mosquitoes following WHO insecticide susceptibility test procedures. Test results were calculated according to WHO bioassay test protocol. Chi-square test was used to determine the significance level of differences between years and study sites. Susceptibility of An. arabiensis to fenitrothion, pirimiphosmethyl and propoxur was 100% in both study villages for three successive years. Resistance to bendiocarb was suspected after two years (2015) in Andassa, but not in Tikurit. Mortality and knock down due to DDT significantly increased from 2013 to 2015 at Tikurit (knock down: χ2 = 117.9, P<.0001 and mortality:  χ2 = 66.3, P<.0001; due to deltamethrin, knock down: χ2 = 7.3, P=.004 and mortality: χ2 = 37.8, P<.0001). The same was true at Andassa (due to DDT, knock down: χ2 = 198.7, P<.0001 and mortality:  χ2 = 82.9, P<.0001; due to deltamethrin, knock down: χ2 = 26.1, P<.0001 and mortality: χ2 = 48.2, P<.0001). Bendiocarb was effective against the An. arabiensis for two years under bendiocarb IRS operation so that alternative insecticides with different mode of action should be replaced every two to three years to prolong its efficacy.
