Trends of stroke subtypes mortality in Sao Paulo, Brazil (1996-2003).

The decline of stroke mortality rates has been described in Brazil; however, there is no data about stroke subtypes. We described the changes of stroke mortality rates in the city of Sao Paulo (1996-2003) emphasizing intracerebral hemorrhage and cerebral infarction. We categorized mortality data by gender and 10-year age-strata from 30 to 79 years-old. For men, an annual reduction of all types of stroke (-3.9%), and of stroke subtypes as intracerebral hemorrhage (-3.0%) and cerebral infarction was observed (-2.7%) as well as, a decline of ill-defined stroke (-7.4%). For women, a decline was observed for all types of stroke (-3.3%) and for ill-defined stroke (-12%). However, the switch of ill-defined cases to stroke subtype categories due to a better clinical diagnosis blurred a real decline of both cerebral infarction and intracerebral hemorrhagic stroke among women.

Progress testing: evaluation of four years of application in the school of medicine, University of São Paulo.

BACKGROUND: Progress testing is a longitudinal tool for evaluating knowledge gains during the medical school years. OBJECTIVES: (1) To implement progress testing as a form of routine evaluation; (2) to verify whether cognitive gain is a continuous variable or not; and (3) to evaluate whether there is loss of knowledge relating to basic sciences in the final years of medical school. METHODS: A progress test was applied twice a year to all students from 2001 to 2004. The mean percentage score was calculated for each school year, employing ANOVA with post hoc Bonferroni test evaluation for each test. RESULTS: Progress testing was implemented as a routine procedure over these 4 years. The results suggest a cognitive gain from first to sixth year in all eight tests, as a continuum (P for trend < .0001). Gain was found to be continuous for basic sciences (taught during the first 2 years), clinical sciences (P < .0001), and clerkship rotation (P < .0001). There was no difference between the performance of men and women. CONCLUSION: Progress testing was implemented as a routine, applied twice a year. Data suggest that cognitive gain during medical training appears to be a continuum, even for basic science issues.

Migraine and coronary heart disease in women and men.

OBJECTIVE: We evaluated migraine as an independent risk factor for subsequent coronary heart disease (CHD) events among women in the Women's Health Study (WHS) and men in the Physicians' Health Study (PHS). BACKGROUND: Although several studies have suggested that migraine is associated with increased risk of stroke, there are few and conflicting data on whether migraine predicts risk of future CHD events. METHODS: The WHS is an ongoing randomized, double-blind, placebo-controlled trial of low-dose aspirin and vitamin E in the primary prevention of cardiovascular disease and cancer in 39876 women health professionals aged > or =45 years in 1993, and the PHS is a completed randomized, double-blind, placebo-controlled trial of aspirin and beta-carotene in the primary prevention of cardiovascular disease and cancer in 22071 men physicians aged 40 to 84 years in 1982. Primary endpoints were defined as major CHD (nonfatal myocardial infarction [MI] or fatal CHD) and total CHD (major CHD plus angina and coronary revascularization). RESULTS: After adjusting for other CHD risk factors, female health professionals and male physicians reporting migraine were not at increased risk for subsequent major CHD (women: relative risk [RR], 0.83; 95% confidence interval [CI], 0.53 to 1.29; men: RR, 1.02; 95% Cl, 0.79 to 1.31) or total CHD (women: RR, 1.01; 95% Cl, 0.76 to 1.34; men: RR, 0.98; 95% Cl, 0.82 to 1.18). When considered separately, there was also no increase in risk of MI or angina. CONCLUSION: These prospective data suggest that migraine is not associated with increased risk of subsequent CHD events in women or men.
