Improvement of Electrical Conductivity of In Situ Iodine-Doped Polypyrrole Film Using Atmospheric Pressure Plasma Reactor with Capillary Electrodes.

To improve the electrical conductivity of polypyrrole (PPy) nanostructure film through in situ iodine (I2) doping, this study proposes an atmospheric pressure plasma reactor (APPR) where heated I2 dopant vapor is fed through capillary electrodes that serve as electrodes for discharge ignition. A large amount of the heated I2 vapor introduced into the reactor separately from a monomer gas can be effectively activated by an intense plasma via capillary electrodes. In particular, intensive plasma is obtained by properly adjusting the bluff body position in the APPR. Based on the ICCD and OES results, the I2 vapor injected through the capillary nozzle electrode is observed to form I2 charge species. The formed I2 species could directly participate in growing in situ I2-doped PPy films. Thus, in situ I2-doped PPy nanostructure films grown using the proposed APPR exhibit higher thicknesses of 15.3 µm and good electrical conductivities, compared to the corresponding non-doped films.

Dietary Diversity and Stunting among Infants and Young Children: A Cross-sectional Study in Aligarh.

CONTEXT: Child undernutrition is a public health problem in a developing country like India. Dietary diversity is an important immediate determinant of undernutrition. AIMS: The aim of this study is to find the prevalence of stunting among infants and young children aged 6-23 months and its association with dietary diversity. SETTINGS AND DESIGN: This study was community-based cross-sectional study. It was carried out in the registered families of the Urban Health Training Centre and Rural Health Training Centre, Department of Community Medicine, Jawaharlal Nehru Medical College, AMU, Aligarh. METHODS: A total of 326 children aged 6-23 months were included in the study. Study tools were predesigned and pretested questionnaire, modified infant and young child feeding practices questionnaire, and infantometer. Systematic random sampling with probability proportionate to size technique was utilized to drawn necessary sample size. STATISTICAL ANALYSIS: Wald's statistics, Z-scores, and bivariate and multivariate logistic regression (LR) (stepwise backward LR) were used. RESULTS: The prevalence of stunting in study population was 45.7% (95% CI - 40.1%, 51.1%); moderate stunting was 33.7% (95% CI - 28.8%, 39%); and severe stunting was 12% (95% CI - 8.8%, 16%). The prevalence of stunting was significantly associated with dietary diversity (OR - 0.17, 95% CI - 0.10-0.29). CONCLUSIONS: The study concludes that dietary diversity is a significant predictor of stunting. Therefore, interventions aimed at improving dietary diversity should be taken to reduce the burden of stunting among infants and young children.

Complementary feeding practices among children aged 6-23 months in Aligarh, Uttar Pradesh.

CONTEXT: Complementary feeding practices play an important role in the growth and development of the children. AIMS: The aim of this study is to determine the prevalence of complementary feeding practices among children aged 6-23 months and its association with various sociodemographic factors. SETTINGS AND DESIGN: The study was a community-based, cross-sectional study conducted at field practice area of Urban Health Training Centre and Rural Health Training Centre, Department of Community Medicine, Jawaharlal Nehru Medical College, Aligarh Muslim University, Aligarh. MATERIALS AND METHODS: Mothers of children aged 6-23 months of age interviewed using the infant and young child feeding questionnaire for complimentary feeding indicators, namely, minimum dietary diversity (MDD), minimum meal frequency (MMF), and minimum acceptable diet (MAD). The sample size drawn was 326 using systematic random sampling with probability proportionate to size. STATISTICAL ANALYSIS USED: Wald's statistics, bivariate and multivariate logistic regression. RESULTS: MDD was adequate in 42.6% children, MMF in 50.9% children, and MAD in 35.6% children. MDD was significantly associated with area of residence, birth order of child, and Standard of living index (SLI); MMF was significantly associated with area of residence, sex of child, and literacy status of mother; MAD was significantly associated with area of residence, sex of child, birth order of child, and SLI. CONCLUSION: The study revealed that approximately 50% of mothers practiced inadequate complementary feeding. The feeding practices were found to be significantly associated with various sociodemographic factors highlighting the importance of addressing these factors if we aim an improvement in feeding practices.

All Slums are Not Equal: Maternal Health Conditions Among Two Urban Slum Dwellers.

BACKGROUND: Pregnant women inhabiting urban slums are a "high risk" group with limited access to health facilities. Hazardous maternal health practices are rampant in slum areas. Barriers to utilization of health services are well documented. Slums in the same city may differ from one another in their health indicators and service utilization rates. The study examines whether hazardous maternal care practices exist in and whether there are differences in the utilization rates of health services in two different slums. MATERIALS AND METHODS: A cross-sectional study was carried out in two urban slums of Aligarh city (Uttar Pradesh, India). House-to-house survey was conducted and 200 mothers having live births in the study period were interviewed. The outcome measures were utilization of antenatal care, natal care, postnatal care, and early infant feeding practices. Rates of hazardous health practices and reasons for these practices were elicited. RESULTS: Hazardous maternal health practices were common. At least one antenatal visit was accepted by a little more than half the mothers, but delivery was predominantly home based carried out under unsafe conditions. Important barriers to utilization included family tradition, financial constraints, and rude behavior of health personnel in hospitals. Significant differences existed between the two slums. CONCLUSION: The fact that barriers to utilization at a local level may differ significantly between slums must be recognized, identified, and addressed in the district level planning for health. Empowerment of slum communities as one of the stakeholders can lend them a stronger voice and help improve access to services.
