Association Between Reported Long Working Hours and History of Stroke in the CONSTANCES Cohort.

Background and Purpose- Long working hours (LWHs) are a potential risk factor for stroke. The aim of this study was to investigate this association in a large general population cohort. Methods- We used the French population-based cohort, CONSTANCES (Cohorte des Consultants des Centres d'Examens de Santé), to retrieve information on age, sex, smoking, and working hours from the baseline, self-administered questionnaire.

Day 1 Extracranial Internal Carotid Artery Patency Is Associated With Good Outcome After Mechanical Thrombectomy for Tandem Occlusion.

Background and Purpose- Optimal management of the extracranial occlusive component remains controversial in patients with acute ischemic stroke by tandem occlusion treated with mechanical thrombectomy. We investigated the association between extracranial internal carotid artery (ICA) patency at day 1 and the clinical outcome after mechanical thrombectomy. Methods- Consecutive patients with acute ischemic stroke with tandem occlusion were identified from a hospital-based prospective registry from 2011 to 2017.

Neurosteroids: regulatory mechanisms in male rat brain during heterosexual exposure.

Pregnenolone (delta 5-P) and dehydroepiandrosterone (DHEA) were measured in the limbic system of young adult male rats (M) exposed for several days to the scent of cycling females but in absence of sexual contacts (M/F), and compared to levels obtained in males similarly exposed to other males (M/M). delta 5-P was highest in the olfactory bulbs of M/M, as compared to other regions of the limbic system. It decreased greater than 50% in M/F olfactory bulbs, but was identical in the olfactory tubercles, the amygdalas and the hypothalamus of M/M and M/F, as well as in the plasma, the adrenals and the spleen (taken as a representative non-endocrine organ).
