Health & Demographic Surveillance System Profile: The Birbhum population project (Birbhum HDSS).

The Birbhum HDSS was established in 2008 and covers 351 villages in four administrative blocks in rural areas of Birbhum district of West Bengal, India. The project currently follows 54 585 individuals living in 12557 households. The population being followed up is economically underprivileged and socially marginalized. The HDSS, a prospective longitudinal cohort study, has been designed to study changes in population demographic, health and healthcare utilization. In addition to collecting data on vital statistics and antenatal and postnatal tracking, verbal autopsies are being performed. Moreover, periodic surveys capturing socio-demographic and economic conditions have been conducted twice. Data on nutritional status (children as well as adults), non-communicable diseases, smoking etc. have also been collected in special surveys. Currently, intervention studies on anaemia, undernutrition and common preschool childhood morbidities through behavioural changes are under way. For access to the data, a researcher needs to send a request to the Data Manager [suri.shds@gmail.com]. Data are shared in common formats like comma-separated files (csv) or Microsoft Excel (xlsx) or Microsoft Access Database (mdb).The HDSS will soon upgrade its data management system to a more integrated platform, coordinated and guided by INDEPTH data sharing policy.

Efficacy of alternate-day versus everyday dosing of atorvastatin.

BACKGROUND: Atorvastatin has a longer duration of action than other hydroxymethylglutaryl coenzyme A reductase inhibitors. OBJECTIVES: The objective was to evaluate the efficacy of alternate day vs. daily dosing of atorvastatin for the treatment of hyperlipidemia. MATERIALS AND METHODS: In this prospective, open label, crossover study, 40 patients with plasma low-density cholesterol (LDL-C) of more than 130 mg/dl and total cholesterol (TC) more than 200 mg/dl were recruited. After baseline tests, they were randomly allocated to two groups. Group A received 20 mg atorvastatin on alternate days and group B received 20 mg atorvastatin daily for 12 weeks. After 4 weeks of washout period, the groups were crossed over to the other treatment regimen for another 12 weeks. Fasting plasma lipid profile and serum alanine transaminase (ALT) and aspartate transaminase (AST) were measured for both groups at 6(th), 12(th), 16(th), 22(nd), and 28(th) weeks. Results were pooled across the periods and data between the two groups were compared using unpaired t-test. RESULTS: Among the 40 enrolled subjects, 38 completed the study. Both treatment regimens significantly reduced LDL-C and TC compared to baseline. There was no statistically significant difference between the two groups in terms of reduction of plasma LDL-C and TC at 6 and 12 weeks of treatment. Both the regimens were well tolerated. CONCLUSION: Alternate-day treatment with atorvastatin is comparable in efficacy and safety to the established daily treatment regimen, thus being a cost effective alternative.

Micro-albuminuria: a predictor of short-term mortality in acute ischaemic stroke.

We studied 89 non-diabetic patients of acute ischaemic stroke, confirmed by imaging, admitted within 24 hours of onset, to investigate the prevalence and significance of micro-albuminuria (MA) as a predictor of in-hospital mortality. Two control groups consisted of 70 patients with non-stroke chronic neurological diseases and 60 age- and sex- matched healthy individuals. Spot urinary albumin-to-creatinine ratio was measured in first morning sample on days 1, 4 and/or 7. Functional status was assessed daily for 7 days by National Institute of Health Stroke Scale (NIHSS). Outcome data were recorded for 14 days. MA was found in 61.79% of acute ischaemic stroke patients on day 1 compared to 13% in non-stroke neurological patients and 7% of healthy controls. Patients with MA were older and had a higher systolic blood pressure. The 14-day disease-specific mortality was higher in patients with MA (25.45%) compared to patients without it (5.88%). High day 1 MA (>100 microg/mg) and rising or static value from day 1 to day 4 or day 7 correlated with statistically more chance of death. Increasing MA had a positive correlation with higher NIHSS score. Thus, MA was found to be a reliable predictor of shortterm in-hospital mortality in acute ischaemic stroke.

Effect of Sonachandi Chyawanprash and Chyawanprash Plus--two herbal formulations on immunomodulation.

The immunomodulatory effects of Sonachandi Chyawanprash and Chyawanprash Plus--two herbal formulations have been evaluated. Both the drugs increased the macrophage activity and their number indicating enhancement of non-specific immune response and reduction of chances of infection. Besides that both Sonachandi Chyawanprash and Chyawanprash Plus efficiently protected Cyclosporine A induced immunosuppression suggesting the immunoprotective role of the aforesaid herbal formulations.
