Using death and functional status as end points, we prospectively analyzed the outcome 6 months after spontaneous intracerebral hemorrhage in 166 patients admitted to an acute-care stroke unit on the first day of their stroke. Seventy-one patients (43%) died, 69 (42%) had a satisfactory outcome, and 26 (16%) had a poor functional outcome. Early (30-day) survival was correlated with morphologic parameters on the initial computed tomogram (hemorrhage size, midline shift, and intraventricular spread of the hemorrhage), while later (6-month) survival was correlated with age. Using logistic regression, we found five independent predictors of satisfactory outcome at 6 months: age, hemorrhage size, intraventricular spread of the hemorrhage, limb paresis, and communication disorders. Of these, age was the most important predictor by far.

This study supports the hypothesis of a relationship between proximal depressive symptomatology and dementia in men, but distant depression did not increase dementia risk in this sample. The results suggest that depression in older men might reflect a form of vascular depression associated with cerebral vascular pathology or multiinfarct disease that may amplify the dementing or declining process, hence accelerating the onset of manifest symptoms of dementia.

The possible modifying effect of social relations on the association between depression and mortality was examined in a community-based cohort study. A total of 3,777 randomly selected persons 65 years of age and older in southwest France were followed over a 5-year period from 1988 in the Personnes Agees Quid (PAQUID). At study entry, the prevalence of elevated depressive symptomatology was 12.9% for men and 14.7% for women, and the reported relative isolation was 14.1% for men and 26.0% for women. During a total of 16,984 person-years of follow-up, 849 deaths occurred. Among participants with high levels of depressive symptomatology, the age-adjusted mortality rate ratio was 2.10 (95% confidence interval 1.7-2.7) in men and 1.76 (95% confidence interval 1.4-2.3) in women. When compared with individuals with the most connections, men and women with few social network connections were also at increased risk of mortality: age-adjusted rate ratio = 2.69 (95% confidence interval 1.9-3.8) for men and 1.56 (95% confidence interval 1.0-2.4) for women. Satisfaction with social support had a small but nonsignificant effect on mortality risk. For women, the excess risks due to depressive symptoms and few network connections are observed only in the 65- to 74-year age group, after adjusting for health and health behaviors. Social relations did not significantly modify the depression-mortality associations for either men or women, although the depression-mortality effect was reduced by 12.8% in men. The latter findings do not appear to be compatible with the buffering hypothesis, whereby we would expect social relations to decrease the depression-mortality association. Nonetheless, there are independent effects from these two factors, and older men who are depressed and not socially connected are at increased risk of dying earlier.

One hundred and ninety-two cases of supratentorial astrocytic tumors are classified in 4 groups according to the presence or absence in the pathological material of simple morphological criteria: abnormal cellular density, nuclear pleomorphism, neovascularization, necrosis. Each one of these criteria is strongly correlated with prognosis. Nevertheless only a simple classification in low and high grade lesions has a definite predictive value. A multivariate analysis utilizing Cox's hazard function confronts these histological findings with a number of clinical and etiological possible factors of prognosis. Age and performance status at the time of diagnosis are the best predictors of survival time. The clinical use of a predictive model derived from Cox's function analysis is discussed.
