Burden and predictors of hypertension in India: results of SEEK (Screening and Early Evaluation of Kidney Disease) study.

BACKGROUND: Hypertension (HTN) is one of the major causes of cardiovascular morbidity and mortality. The objective of the study was to investigate the burden and predictors of HTN in India. METHODS: 6120 subjects participated in the Screening and Early Evaluation of Kidney disease (SEEK), a community-based screening program in 53 camps in 13 representative geographic locations in India. Of these, 5929 had recorded blood pressure (BP) measurements. Potential predictors of HTN were collected using a structured questionnaire for SEEK study. RESULTS: HTN was observed in 43.5% of our cohort. After adjusting for center variation (p < 0.0001), predictors of a higher prevalence of HTN were older age ≥ 40 years (p < 0.0001), BMI of ≥ 23 Kg/M2 (p < 0.0004), larger waist circumference (p < 0.0001), working in sedentary occupation (p < 0.0001), having diabetes mellitus (p < 0.0001), having proteinuria (p < 0.0016), and increased serum creatinine (p < 0.0001). High school/some college education (p = 0.0016), versus less than 9th grade education, was related with lower prevalence of HTN. Of note, proteinuria and CKD were observed in 19% and 23.5% of HTN subjects. About half (54%) of the hypertensive subjects were aware of their hypertension status. CONCLUSIONS: HTN was common in this cohort from India. Older age, BMI ≥ 23 Kg/M2, waist circumference, sedentary occupation, education less, diabetes mellitus, presence of proteinuria, and raised serum creatinine were significant predictors of hypertension. Our data suggest that HTN is a major public health problem in India with low awareness, and requires aggressive community-based screening and education to improve health.

Partial versus full hospitalization for adults in psychiatric distress: a systematic review of the published literature (1957-1997).

OBJECTIVE: The authors reviewed published research that compared partial and full hospitalization as alternative programs for the care of mentally ill adults, with the goal of both systematizing the knowledge base and providing directions for future research. METHOD: Studies published since 1950 were obtained through manual and electronic searches. Results were stratified by outcome domain, type of measure used to report between-group differences (global, partial, or rate-based), and time of assessment. Effect sizes were computed and combined within a random-effects framework. RESULTS: Eighteen investigations published between 1957 and 1997 were systematically reviewed. Over half of eligible patients were excluded a priori; diagnostic severity of enrollees varied widely. On measures of psychopathology, social functioning, family burden, and service utilization, the authors found no evidence of differential outcome in the selected patient population admitted to the studies reviewed. Rates of satisfaction with services suggested an advantage for partial hospitalization within 1 year of discharge, with the gap being largest at 7-12 months. CONCLUSIONS: Although partial hospitalization is not an option for all patients requiring intensive services, outcomes of partial hospitalization patients in these studies were no different from those of inpatients. Further, patients and families were more satisfied with partial hospitalization in the short term. Weaknesses of the studies limited the scope of our inquiry and the generalizability of findings. Positive findings require replication under the present circumstances of mental health care, and more research is needed to identify predictors of differential outcome and successful partial hospitalization. A clearer definition of partial hospitalization will help consolidate its role in the continuum of mental health services.

A randomized control trial of cardiac rehabilitation.

A randomized trial using controls tested whether psycho-social rehabilitation of acute myocardial infarction (MI) patients would improve significantly their return to work rate and assessed the importance of various psychological, social, occupational, socio-demographic, and medical factors in facilitating or impeding rapid return to work. Eighty-nine patients were assigned randomly to participate in an experimental cardiac rehabilitation program (rehab care), and 91 patients were controls who received conventional hospital rehabilitation (usual care). By the first follow-up interview at three months, patients assigned to experimental treatment were significantly less distressed psychologically and less dependent on family support than controls (P = 0.04 and P = 0.05, respectively). By the final follow-up interview at 13 months, there was a marginally significant difference in favor of the experimental group in the frequency of reported deterrents to work resumption (P = 0.07). However, the intervention did not result in a statistically significant difference in the return to work rate (P greater than 0.10). In each group, 88% were back at work by approximately the first year after infarction. In addition, the two groups were similar in the amount of time patients remained out of the workforce (median days rehab care = 75, usual care = 81; P greater than 0.10). A multi-stage data analysis procedure utilizing the Cox regression technique indicated that while several independent variables had significant univariate associations with the length of time patients convalesced, outcome was most influenced by the patient's initial cardiological status and clinical course, by the patterns of family support, and by the several variables measuring the presence of obstacles to resuming work. Our findings suggest that rehabilitation programs intervening on multiple levels (psychological, social, occupational, and physical) may best meet the needs of chronically ill cardiac patients. Results indicate that implementing measures addressing the patient's general psycho-social adjustment to MI may improve existing programs.

A phase I study of ampligen in human immunodeficiency virus-infected subjects.

Ampligen, poly(I)n:poly(C12U)n, was administered intravenously to 39 human immunodeficiency virus (HIV)-infected subjects, asymptomatic or with early AIDS-related complex (ARC) and with CD4+ cell counts less than 500/mm3 in a phase I dose-escalation study. Six doses ranging from 10 to 570 mg/m2 were administered twice-weekly for 9-25 weeks to groups of 5-7 subjects. There was no significant effect on HIV as measured by serum p24 levels, the proportion of patients from whom HIV could be cocultured from blood, or the concentration of peripheral mononuclear cells positive for the virus. Although patients on 10 and 40 mg/m2 showed a significant decline in CD4+ cell counts, as would be expected in untreated patients, patients who received doses greater than or equal to 120 mg/m2 showed no significant decline in CD4+ cell counts. In addition, there was a significant increase in CD4+ cell counts with respect to dose of ampligen. This effect of ampligen and the fact that it has been shown to act synergistically with zidovudine against HIV in vitro suggest that the combination might be tried clinically in patients.
