    International audienceDespite major improvements in primary prevention and acute treatment over the last decades, stroke is still a devastating disease. At the beginning of the 21st century, the age-standardized incidence of stroke in Europe ranged from 95 to 290/100,000 per year, with one-month case-fatality rates ranging from 13 to 35%. Approximately 1.1 million inhabitants of Europe suffered a stroke each year, and ischemic stroke accounted for approximately 80% of cases. Although global stroke incidence is declining, rates observed in young adults are on the rise, thus suggesting a need for strategies to improve prevention. In addition, because of the ageing population, the absolute number of stroke is expected to dramatically increase in coming years: by 2025, 1.5 million European people will suffer a stroke each year. Beyond vital prognosis, stroke patients are also at increased risk of poor outcome within the first year of the event including re-hospitalisation (33%), recurrent event (7 to 13%), dementia (7 to 23%) mild cognitive disorder (35 to 47%), depression (30 to 50%), and fatigue (35% to 92%), all of them contributing to affect health related quality of life. Given these observations, an urgent development of acute care provision, as well as resources for post-stroke therapeutic strategies, is needed

    Mortality following stroke during and after acute care according to neighbourhood deprivation: a disease registry study

    International audienceBackground: Neighbourhood deprivation has been shown to be inversely associated with mortality 1 month after stroke. Whether this disadvantage begins while patients are still receiving acute care is unclear. We aimed to study mortality after stroke specifically in the period while patients are under acute care and the ensuing period when they are discharged to home or other care settings. Methods: Our sample includes 1760 incident strokes (mean age 75, 48% men, 86% ischaemic) identified between 1998 and 2010 by the population-based stroke registry of Dijon (France). We used Cox regression to study all-cause mortality up to 90 days after stroke occurrence. Results: Overall, 284 (16.1%) patients died during the 90 days following stroke. Prior to stroke, risk factors prevalence (eg, high blood pressure and diabetes) and acute care management did not vary across deprivation levels. There was no association between deprivation and mortality while patients were in acute care (HR comparing the highest to the lowest tertiles of deprivation: 1.01, 95% CI 0.71 to 1.43). After discharge, however, age and gender adjusted mortality gradually increased with deprivation (HR 2.08, 95% CI 1.07 to 4.02). This association was not modified when stroke type and severity were accounted for. Conclusions: The gradient of higher poststroke mortality with increasing neighbourhood deprivation was noticeable only after acute hospital discharge. Quality of postacute care and social support are potential determinants of these variations

    International audienceWe aimed to investigate associations between serum thyroid stimulating hormone (TSH) levels and both severity and outcome after ischemic stroke (IS). A total of 731 patients consecutive IS patients were enrolled (mean age 69.4 +/- 15.4, 61.6% men), and serum TSH levels were measured at admission and analyzed according to the tertiles of their distribution (1.6 mUI/l). Associations between TSH and both severity at admission (National Institutes of Health Stroke Scale (NIHSS) scores = 5) and functional outcome at discharge assessed by the modified Rankin Scale were analyzed using logistic regression and ordinal logistic regression models, respectively. High TSH levels were independently associated with both a decreased risk of NIHSS score >= 5 at admission (prevalence proportion ratio = 0.62; 95% CI 0.41-0.94, p = 0.024 for tertile 3 vs. tertile 1). In addition, patients with high TSH levels had a better functional outcome at discharge (OR 0.43; 95% CI 0.30-0.60, p < 0.001 for tertile 2 vs. tertile 1; OR 0.39; 95% CI 0.27-0.56, p < 0.001 for tertile 3 vs. tertile 1). The mechanisms underlying these associations and their potential exploitation in terms of therapeutic strategies need to be explored

    International audienceDespite a common pathophysiological mechanism, i.e. atherosclerosis, and similar vascular risk factors, few reliable studies have compared the epidemiology of stroke and acute myocardial infarction (AMI)

    Trends in case-fatality rates in hospitalized nontraumatic subarachnoid hemorrhage: results of a population-based study in Dijon, France, from 1985 to 2006.

    International audienceBACKGROUND: Subarachnoid hemorrhage accounts for 2% to 5% of all strokes and is associated with high morbidity and mortality rates. Reports in the literature show that case-fatality rates vary with time and according to geographical area. OBJECTIVE: The objective of the study was to evaluate the case-fatality rates in subarachnoid hemorrhage at 1 and 6 months and to determine trends in these rates over 22 years using a population-based registry. METHODS: The Dijon Stroke Registry has enabled us to perform a comprehensive analysis of subarachnoid hemorrhage diagnosed in a population of >150 000 inhabitants hospitalized between 1985 and 2006 in the Dijon University Hospital, which has both a neurosurgery unit and a neuroradiology unit. Diagnosis was based on clinical and neuroimaging features and, when necessary, on lumbar puncture. RESULTS: Case-fatality rates for hospitalized subarachnoid hemorrhages at 1 and 6 months were 15.59% (95% confidence interval [CI], 9.37-25.34) and 16.84% (95% CI, 10.33-26.78), respectively. From 1985 to 1995, case-fatality rates for SAH at 1 and 6 months were 17.1% (95% CI, 8.1-34.2) and 17.7% (95% CI, 9.6-31.3), whereas from 1996 to 2006, they were 20.2% (95% CI, 10.2-37.8) and 19.7% (95% CI, 11.1-33.6), respectively. CONCLUSION: Case-fatality rates for hospitalized subarachnoid hemorrhages in this population-based study remained stable over 22 years, suggesting that this stroke subtype is still a very severe disease despite early management. Most deaths occurred during the first 30 days. Further work is necessary to evaluate levels of prehospital case-fatality in our population-based registry
