Randomized Controlled Trial Comparative StudyStandard WHO-ORS versus reduced-osmolarity ORS in the management of cholera patients.
The study compared the safety and efficacy of an oral rehydration salts (ORS) solution, containing 75 mmol/L of sodium and glucose each, with the standard World Health Organization (WHO)-ORS solution in the management of ongoing fluid losses, after initial intravenous rehydration to correct dehydration. The study was conducted among patients aged 12-60 years hospitalized with diarrhoea due to cholera. One hundred seventy-six patients who were hospitalized with acute diarrhoea and signs of severe dehydration were rehydrated intravenously and then randomly assigned to receive either standard ORS solution (311 mmol/L) or reduced-osmolarity ORS solution (245 mmol/L). ⋯ Reduced-osmolarity ORS solution was as efficacious as standard WHO-ORS solution in the management of cholera patients. The results indicate that reduced-osmolarity ORS solution is also as safe as standard WHO-ORS solution. However, because of the limited sample size in the study, the results will have to be confirmed in trials, involving a larger number of patients.

Seeking optimal means to address micronutrient deficiencies in food supplements: A case study from the Bangladesh Integrated Nutrition Project.
In seeking to improve the micronutrient contents of a food supplement used in a major community-based nutrition project in Bangladesh, operations research was conducted to compare the provision of needed micronutrients through additional food sources (fresh or dried fruits or vegetables), a micronutrient multi-mix, and a combination of the two. Micronutrient gaps (the difference between micronutrient requirements and actual micronutrient intake) were estimated for four groups of project beneficiaries, with target intakes defined as requirements for iron, calcium, zinc, vitamin A, vitamin C, riboflavin, niacin, and vitamin B12 recommended by the Food and Agriculture Organization/World Health Organization. Primary focus was placed on iron and vitamin A. ⋯ In terms of these analyses, the micronutrient multimix proved, by far, to be the most advantageous. Food options, however, are arguably desirable in that they provide dietary benefits additional to that of known micronutrients and may increase demand to boost production of domestic fruits and vegetables for the population as a whole. The study concludes that it is cost-effective to use powdered micronutrient mixes for such specific purposes as enrichment of supplementary food and food fortification, but encourages production and consumption of micronutrient-rich foods through programme messages and activities.

Socioeconomic differentials in supplementation of vitamin A: evidence from the Philippines.
The efficacy of supplementation of vitamin A in child survival has been well-demonstrated. However, the effectiveness of a programme of vitamin A supplementation at the population level has been rarely examined. Understanding how programmes reach disadvantaged children can help improve the design of initiatives of vitamin A supplementation. ⋯ This disparity increased between the surveys: the adjusted odds of vitamin A intake by poor households compared to middle-class households declined from 0.73 [95% confidence interval (CI) 0.61-0.87) in 1993 to 0.52 (95% CI 0.42-0.63)] in 1998, resulting in an increased health inequity. The vitamin A programme in the Philippines was not uniformly successful in reaching the most vulnerable children. Approaches targeting vulnerable households or approaches not requiring mothers to travel to distribution centres may be more promising.

This study was carried out to determine the incidence and causes of maternal deaths about a 20-year period at the Zekai Tahir Burak Women's Health Education and Research Hospital (ZTBWHERH), Ankara, Turkey. All maternal deaths from January 1982 to July 2001 were reviewed and classified retrospectively. Using a computer-generated list, 348 patients admitted to the Labour Department of ZTBWHERH during 1982-2001 were selected as controls. ⋯ The problem of maternal mortality remains multifactorial. Short-term objectives should be focused on improving both medical and administrative practices. Improving the status of women will necessarily remain a long-term objective.
