Background: One of the key strategies in the HIV/AIDS prevention and control programs in Nigeria is Voluntary HIV counseling and testing (VCT). However, its utilization among young adults, particularly undergraduates, is very low. The aim of the present study was to determine the prevalence and predictors of non-uptake of VCT among undergraduates. Methods: A cross sectional study using quantitative methods was conducted. Using simple random sampling, three faculties were selected out of nine and 422 respondents were selected from three faculties. Interviews were conducted using pre-tested semi-structured questionnaires. Data analysis was done using statistical package for social sciences version 20. Prevalence was measured by the percentage of respondents that had never used VCT. Analytical statistics were done using chi-square test to measure strength of association between VCT uptake and knowledge and attitude of respondents. Association with P-value 0.05 was considered significant. Logistic regression was used to identify predictors of non-uptake of VCT. The associations were presented as odds ratios (OR) and 95% confidence intervals. Results: Overall, 59.3% of respondents were knowledgeable about VCT while majority, 64.7% had negative attitude towards it. Knowledge (X2 = 9.89, P-value 2e="font-family:Verdana;"> = 10.78, P-

High postharvest losses in developing countries negate the efforts geared towards improving food security. Poor produce quality including high prevalence of mycotoxin contamination is another significant problem. Appropriate postharvest handling and processing provide opportunities to reduce postharvest losses and improve food safety. This study was aimed at establishing the postharvest handling practices and estimating qualitative and quantitative postharvest losses for maize, millet, sorghum, beans, groundnuts, cassava, and sweet potatoes among farmers in 3 districts (Kamuli, Apac and Nakasongola) in Uganda, representing different agro-ecological zones. The study was done in late August 2014 after the first season harvests (June-August). Farmer interviews, focus group discussions and key informant interviews were used to collect data on postharvest loss estimates and postharvest handling practices. Samples of the different foods were collected and analyzed for physical quality characteristics, mould count and aflatoxin contamination using standard laboratory procedures. The results show predominance of rudimentary and inappropriate postharvest handling methods. Postharvest loss estimates were generally high, with values of 41%, 33%, 33%, 26%, 31%, 22%, 17% and 19% for maize, millet, sorghum, beans, groundnuts, cowpea, sweet potatoes and cassava respectively. The highest loss for all the crops was recorded at storage. Prevalence of aflatoxin contamination was 44%, 91%, 55%, 36%, 35% and 60% for maize, sorghum, groundnuts, millet, sweet potatoes and cassava respectively. Sorghum, maize and groundnuts were found to have the highest aflatoxin contamination levels. Chi-square test (p = 0.024, odds ratio = 5) showed that grain dried on bare ground had higher aflatoxin levels than that dried on a covered surface. The findings of this study reveal a serious need for postharvest interventions as a strategy to address food security.

Background:Developing appropriate concussion prevention and management paradigms in middle school(MS)settings requires understanding parents’general levels of concussion-related knowledge and *** study examined factors associated with concussion-symptom knowledge and care-seeking attitudes among parents of MS children(aged 10-15 years).Methods:A panel of 1224 randomly selected ***,aged ≥18 years and identifying as parents of MS children,completed an online questionnaire capturing parental and child *** parents’concussion-symptom knowledge was measured using 25 questions,with possible answers being“yes”,“maybe”,and“no”.Correct answers earned 2 points,“maybe”answers earned 1 point,and incorrect answers earned 0 point(range:0-50;higher scores=better knowledge).Concussion care-seeking attitudes were also collected using five 7-point scale items(range:5-35;higher scores=more positive attitudes).Multivariable ordinal logistic regression models identified predictors of higher *** met proportional odds *** odds ratios(aORs)with 95%confidence intervals(95%CIs)(excluding 1.00)were deemed statistically ***:Median scores were 39(interquartile range:32-44)for symptom knowledge and 32(interquartile range:28-35)for care-seeking *** multivariable models,odds of better symptom knowledge were higher in women ***(aOR=2.28;95%CI:1.71-3.05),white/non-Hispanics *** racial or ethnic groups(aOR=1.88;95%CI:1.42-2.49),higher parental age(10-year-increase aOR=1.47;95%CI:1.26-1.71),and greater competitiveness(10%-scale-increase aOR=1.24;95%CI:1.13-1.36).Odds of more positive care-seeking attitudes were higher in white/non-Hispanics *** racial or ethnic groups(aOR=1.45;95%CI:1.06-1.99)and in older parental age(10-year-increase aOR=1.24;95%CI:1.05-1.47).Conclusion:Characteristics of middle school children’s parents(e.g.,sex,race or ethnicity,age)are associated with their concussion-symptom knowle

Microuidic channels play a vital role in separation of analytes of interest such as bacteria and platelet cells,etc.,in various biochemical diagnosis procedures including urinary tract infections(UTI)and bloodstream *** paper presents the multi physics computational model specifically designed to study the effects of design parameters of a microuidics channel for the separation of escherichia coli(***)from various blood constituents including red blood cells(RBC)and platelets.A standard two inlet and a two outlet microchannel of length 805µm with a channel width of 40µm is *** effect of electrode potentials and the effect of electrode placement along the channel length and also the levitation of electrodes from the channel wall are studied to optimize the selective particle separation *** results show the efcient separation of e-coli with a mean diameter 0.68µm is achieved at low voltages(less than 20 V)when electrodes placed near to the micro channel and also noticed that the applied electric potential is inversely proportional to the number of electrodes placed along the microuidic *** computer aided multi physics simulations with multiple governing parameters could be advantage in design optimization of microuidics channels and support precise bioparticle separation for better diagnosis.
