The composite and film hardness of TiN coatings prepared by cathodic arc evaporation

Abstract: On the basis of the relative volume deformation of film and substrate, a new model of the composite hardness equation is presented for thin surface coatings. A solution is applied to arc evaporated TiN films with 0.5–3.0 μm thickness on stainless steel 304 and tool steel M2. The model shows that the hardness of deposited films and of the substrate materials can simultaneously be obtained from the experimental composite hardness as a function of indentation diagonal length.

Adherence to antiretroviral therapy (ART) during the early months of treatment in rural Zambia: influence of demographic characteristics and social surroundings of patients

Abstract: Around 70% of those living with HIV in need of treatment accessed antiretroviral therapy (ART) in Zambia by 2009. However, sustaining high levels of adherence to ART is a challenge. This study aimed to identify the predictive factors associated with ART adherence during the early months of treatment in rural Zambia. This is a field based observational longitudinal study in Mumbwa district, which is located 150 km west of Lusaka, the capital of Zambia. Treatment naive patients aged over 15 years, who initiated treatment during September-November 2010, were enrolled. Patients were interviewed at the initiation and six weeks later. The treatment adherence was measured according to self-reporting by the patients. Multiple logistic regression analysis was performed to identify the predictive factors associated with the adherence. Of 157 patients, 59.9% were fully adherent to the treatment six weeks after starting ART. According to the multivariable analysis, full adherence was associated with being female [Adjusted Odds Ratio (AOR), 3.3; 95% Confidence interval (CI), 1.2-8.9], having a spouse who were also on ART (AOR, 4.4; 95% CI, 1.5-13.1), and experience of food insufficiency in the previous 30 days (AOR, 5.0; 95% CI, 1.8-13.8). Some of the most common reasons for missed doses were long distance to health facilities (n = 21, 53.8%), food insufficiency (n = 20, 51.3%), and being busy with other activities such as work (n = 15, 38.5%). The treatment adherence continues to be a significant challenge in rural Zambia. Social supports from spouses and people on ART could facilitate their treatment adherence. This is likely to require attention by ART services in the future, focusing on different social influences on male and female in rural Zambia. In addition, poverty reduction strategies may help to reinforce adherence to ART and could mitigate the influence of HIV infection for poor patients and those who fall into poverty after starting ART.

Practices and determinants of delivery by skilled birth attendants in Bangladesh

Abstract: Utilization of Skilled Birth Attendants (SBAs) at birth is low (20%) in Bangladesh. Birth attendance by SBAs is considered as the “single most important factor in preventing maternal deaths”. This paper examined the practices and determinants of delivery by SBAs in rural Bangladesh. The data come from the post-intervention survey of a cluster-randomized community controlled trial conducted to evaluate the impact of limited post-natal care (PNC) services on healthcare seeking behavior of women with a recent live birth in rural Bangladesh (n = 702). Multivariable logistic regression model was used to identify the potential determinants of delivery by SBAs. The respondents were aged between 16 and 45, with the mean age of 24.41 (± 5.03) years. Approximately one-third (30.06%) of the women had their last delivery by SBAs. Maternal occupation, parity, complications during pregnancy and antenatal checkup (ANC) by SBAs were the significant determinants of delivery by SBAs. Women who took antenatal care by SBAs were 2.62 times as likely (95% CI: 1.66, 4.14; p < 0.001) to have their delivery conducted by SBAs compared to those who did not, after adjusting for other covariates. Our findings suggest that ANC by SBAs and complications during pregnancies are significant determinants of delivery by SBAs. Measure should be in place to promote antenatal checkup by SBAs to increase utilization of SBAs at birth in line with achieving the Millennium Development Goal-5. Future research should focus in exploring the unmet need for, and potential barriers in, the utilization of delivery by SBAs.

Malnutrition among children in rural Malawian fish-farming households

Abstract: To estimate the impact of fish farming operated at household level on nutritional status among children 6-59 months of age, a cross-sectional study was conducted in Zomba district, Malawi. Anthropometric measurements of 66 children in each type of household (fish-farming and non-fish-farming households) and structured interviews with their parents were undertaken. A total of 21 background variables were employed and examined using bivariate and multivariate analyses. Overall, a lower prevalence of malnutrition was detected among the children in fish-farming households than those in non-fish-farming households in all the malnutrition indicators, i.e. stunting, underweight and wasting. In particular, a significantly lower prevalence was detected among the children in fish-farming households than those in non-fish-farming households in both severe (P=0.045) and global underweight (P=0.042). 'Higher proportion of income from fish farming to total income', 'more frequent intake of oil and fats other than never/seldom' and 'breastfeeding practice for the appropriate duration' are the protective factors against being underweight. Household fish farming may have indirectly contributed to lower prevalence of underweight through increasing frequency of intake of oil and fats by strengthening households' purchasing power. The study supports 12 months as the threshold for appropriate breastfeeding duration.
