Life Events as Risk Factors for Myocardial Infarction: A Pilot Case-control Study in Kolkata, India

This case-control study was conducted in the Cardiology Department of Medical College, Kolkata, India, during 2000-2001, to explore the link between stressful life events and subsequent myocardial infarction (MI). One hundred consecutive confirmed MI patients were selected as a case group. One hundred age-, sex- and income-matched controls were selected from visitors other than relatives who attended these patients. The subjects were interviewed and asked to rate 61 life events with a number between 0 and 20. They also noted which of these they had experienced in the last one year. The main exposure variables included life events as per E.S. Paykel, smoking, alcohol consumption, chewing of tobacco, marital status, literacy, employment, and monthly per-capita income. The results showed that an MI patient was likely to experience 4.16 stressful life events, which were twice as much as the control group (2.24). The total stress score was the highest for serious personal illness followed by illness of family members and unemployment for the MI patients. For the controls, conflict between husband and wife, death of friends, and personal illness had the highest total stress score. The mean stress score for the MI patients was 35.5 compared to 17.35 among the controls. The MI subjects were more likely to have experienced stressful life events than the controls

A retrospective cohort study on effect of literacy status of HIV-positive pregnant women on possibility of child getting HIV infected

Introduction: Prevention of parent-to-child transmission (PPTCT) program aims at reduction of HIV transmission through vertical route. Although medical intervention reduces chance of HIV transmission substantially, several demographic factors are often contributory. Minimum literacy is required for HIV-infected individuals to understand the course of medicine and to ensure compliance to the treatment which may have impact on vertical transmission. The objective of this study is to analyze relationship between maternal education and possibility of her babies to get HIV infected. Materials and Methods: A retrospective cohort study was carried out through analysis of secondary data during the period from April 13 to September 16 from all stand-alone integrated counseling and testing centers in West Bengal. A total number of 326 HIV-exposed babies, whose 6th week HIV-Polymerase Chain Reaction (PCR) reports are available and both the mother-baby received PPTCT services, were recruited in the study, and their maternal literacy status was substantiated and analyzed. Results: HIV positivity among HIV-exposed babies was found to be 6.67% whose mothers were illiterate as compared to 5.55% whose mothers were literate up to primary standard and 3.93% whose mothers were educated up to secondary standard. HIV positivity among the exposed babies whose mothers studied higher secondary standard or above showed zero HIV positivity. Chi-square was done to ascertain statistical significance but result was inconclusive although the trend shows increasing chance of HIV-exposed babies to get infected with decreasing literacy. Conclusion: Maternal literacy status favorably influences vertical transmission of HIV
