Diarrhoea is a major cause of childhood morbidity and mortality globally. While the childhood diarrhoea and its association with child feeding, and hygiene, hand washing and water treatment are studied elsewhere, the association of water handling and child feeding with childhood diarrhoea is an understudied area in Nepal. This study aimed to investigate the association of water handling and child feeding practice with childhood diarrhoea among children of one to five years of age in Southern, Nepal. A cross-sectional study was conducted in the Dhanusha district of Southern Nepal in 2013. A total of 284 mother-child pairs were selected using systemic random sampling. A four-week prevalence of childhood diarrhoea was reported using frequency distribution. The association of childhood diarrhoea with water handling and child feeding practices was ascertained using multiple logistic regressions after adjusting for potential confounders. The result of the study demonstrated that the four-week prevalence of childhood diarrhoea was 36.6%. Our finding showed that unsafe water handling practices were associated independently with childhood diarrhoea: untreated water (aOR 3.55; 95% CI: 1.13-11.10), uncovered water (aOR 2.14; 95% CI: 1.09-4.19). Similarly, partial breast feeding (aOR 4.35; 95% CI: 1.87-10.12) was also associated with higher odds of childhood diarrhoea. One third of children in Southern Nepal still had diarrhoea within the four weeks preceding the survey. As poor water handling and sub optimal infant feeding practice were major risk factors contributing to such a high burden of the disease, health promotion strategies such as promotion of safe water handling, improved hygiene and child feeding practices are recommended for the prevention of childhood diarrhoea in Southern Terai of Nepal.

Ubiquitous fine particulates can readily be bound to toxic metals and polycyclic aromatic hydrocarbons and are considered to be a great threat to human health. The purpose of this study was to assess the magnitude of air pollution risks to public health by determining four crucial parameters- inhalable particulates, metals in particulates and PAHs which are associated with PM₁₀ in the air environment of Lucknow, India during 2007-09. The values of PM₁₀ and PM₂.₅ ranged between 102.3-240.5 and 28.0-196.9 μg/m³ whilst the average PM₁₀ was 1.7 times and PM was 1.5 times higher than their respective NAAQS of 100 and 60 μg/m³ respectively. The estimated relative death rate and hospital admissions for each increase in the PM₁₀ levels of 10 μg/m³ ranged from 1.5-8% and from 3.9-8.0% (as per APHEA2 1990) respectively in persons > 65 yrs. Among the locations; AQ, AQ and AQ (with diversified activities and heavy traffic) recorded higher concentrations of both the particulate fractions than the AQ (residential area with low traffic). The average concentrations of Fe, Pb, Ni, Cu, Cr, Cd in PM₁₀ were 219.4, 40.6, 35.1, 27.3, 22.2 and 16.2 ng/m³ and that in PM₂.₅ were 54.3, 33.9, 38.5, 29.4, 8.4, and 1.17 ng/m³ respectively Regression analysis revealed that correlation of metals with PM₂.₅ was stronger than PM. The ratio of metals adsorbed on surface of particles (PM₂.₅:PM₁₀) reveals that PM₂.₅ has more affinity for Ni, Cu and Pb and PM₁₀ for Cd, Fe and Cr. Health risk due to carcinogenic metals bound to respirable particulates was predicted by estimating excess cancer risk (ECR). The highest ECR value was estimated for Cr, 266.70 × 10⁻⁶, which was associated with PM10 and 100.92 × 10⁻⁶ which was associated with PM₂.₅, whereas lead has the lowest ECR value. Amongst PAHs, benzo(a)pyrene (51.96 ± 19.71 ng/m) was maximum in PM₁₀ samples. Maximum concentrations of PM₁₀, PM₂.₅, metals and PAHs were detected during winter, and the lowest was during monsoon. The higher prevalence of diseases among the population may be due to high concentration of particulates coated with toxic metals and PAHs present in air environment.
The PM(10) concentration (μg/m(3)) in Lucknow city at 4 locations in three different seasons ranged between 148.6-210.8 (avg. 187.2 ± 17.1) during summer, 111.8-187.6 (avg. 155.7 ± 22.7) during monsoon and 199.3-308.8 (avg. 269.3 ± 42.9) during winter while PM(2.5) ranged between 32.4-67.2 (avg. 45.6 ± 10.9), 25.6-68.9 (avg. 39.8 ± 4.6) and 99.3-299.3 (avg. 212.4 ± 55.0) during respective seasons. The mass fraction ratio of PM(2.5) ranged between 0.22-0.92 (avg. 0.42 ± 0.26) and was significantly high during winter season indicating their composition.
Background: Dairy products like ice cream, yogurt and buttermilk are consumed widely due to their rich taste but these products lack anthocyanins, which are polyphenol and exhibit great antioxidant activity in both in vivo and in vitro studies. Therefore, adding a natural source of these antioxidants to the commonly consumed dairy product will be beneficial to the masses. Among all the sources, black carrots are the extraordinary and cheapest source of anthocyanins, which are commonly consumed as a natural fermented drink. In this study, an attempt has been made to examine the feasibility of black carrot concentrate as an ingredient into dairy products. Methodology: Ice cream, yogurt and buttermilk were prepared by incorporating black carrot concentrate at 2.5, 5.0, 7.5 and 10% level and were subjected to sensory analysis. The most acceptable products with 7.5% black carrot concentrate were analyzed for minerals, polyphenols and antioxidant activity. Effects of storage on physicochemical, microbial and sensory attributes of black carrot concentrate incorporated dairy products were further analyzed. Results: Sensory analysis revealed that black carrot concentrate could be used up to 7.5% as an ingredient into dairy product with high acceptability. Significant improvement in mineral content (Mg and Fe), polyphenols and antioxidant activity were reported in black carrot concentrate added dairy products. Developed dairy products exhibited an excellent amount of 24.52-113.27 mg/100g anthocyanins. Flavonoids increased by 14.52-34.62 times and Folin-Ciocalteu reducing capacity increased by 26.39-35.87 times in experimental dairy products. The storage study revealed that ice cream could be stored for more than 60 days, yogurt up to 5 days and buttermilk up to 10 days with excellent stability attributes. Conclusion: Incorporation of black carrot concentrate at the level of 7.5% resulted in high acceptability and exceptional nutraceutical property of dairy products. Incorporation of black carrot concentrate into dairy products would enhance the nutraceutical properties and mineral content of food, which could be highly significant in preventing hidden hunger and oxidative stress-induced disorders in developing countries.
<p>The status of the Fishing Cat <em>Prionailurus viverrinus</em> in Koshi Tappu Wildlife Reserve, Nepal was assessed by camera trapping and pugmark searches from 2011 to 2014. The reserve is a highly dynamic and unstable snow-fed braided river system with many anabranches and islands. Evidence of Fishing Cats was found throughout most of the reserve. They were probably more abundant on the eastern side, among the islands of the main river channel, and in the adjacent buffer zone where there was a chain of fishponds and marsh areas fed by seepage from the main river channel. Evidence of Fishing Cats was found up to 6km north of the reserve on the Koshi River but not beyond this. The population is probably small and may be isolated but given the endangered status of the species, is significant. The main likely threats identified are wetland and riparian habitat deterioration caused by over exploitation and illegal grazing by villagers, overfishing of wetlands and rivers within the reserve, and direct persecution arising from perceived conflicts with fish farming and poultry husbandry. Required conservation actions are discussed.</p><div> </div>
