Validation of the Argentine version of the Montreal Cognitive Assessment Test (MOCA): A screening tool for Mild Cognitive Impairment and Mild Dementia in Elderly.

Unlabelled: The MoCA is a brief useful test to diagnose mild cognitive impairment (MCI) and mild dementia (MD). To date, no Argentine cross-cultural adapted validations of the Spanish version have been reported.

Objective: To validate the MoCA in the elderly and study its usefulness in MCI and MD.

Higher frequency of atrial fibrillation linked to colder seasons and air temperature on the day of ischemic stroke onset.

Background: Whether a seasonal variation of atrial fibrillation among acute ischemic stroke (AIS) patients occurs is unknown. We studied the distribution of atrial fibrillation across seasons and air temperatures in a cohort of AIS patients.

Methods: We selected 899 AIS patients from the Argentinean Stroke Registry (ReNACer), who were admitted to 43 centers in the Province of Buenos Aires.

Unemployment: a social risk factor associated with early ischemic stroke mortality? Results from the Argentinean National Stroke Registry (ReNACer).

Employment is an indicator of socioeconomic status. Unemployment is a worldwide social challenge, especially in emerging countries, accounting for a proportion of the overall higher mortality rates found in these nations. We assessed the relationship between employment status and in-hospital mortality among acute ischemic stroke patients participating in the Argentinean National Stroke Registry (ReNACer), a prospective, country-wide, hospital-based stroke registry aimed at improving quality of stroke care in Argentina.
