rMMSE-T had a high reliability and validity. It will be more appropriate to use the revised test and the new cut-off point for the diagnosis and screening of dementia among community-dwelling Turkish elderly population.

Background Mortality in critically ill patients with coronavirus disease 2019 (COVID‐19) is high, therefore, it is essential to evaluate the independent effect of new‐onset atrial fibrillation (NOAF) on mortality in patients with COVID‐19. We aimed to determine the incidence, risk factors, and outcomes of NOAF in a cohort of critically ill patients with COVID‐19. Methods We conducted a retrospective study on patients admitted to the intensive care unit (ICU) with a diagnosis of COVID‐19. NOAF was defined as atrial fibrillation that was detected after diagnosis of COVID‐19 without a prior history. The primary outcome of the study was the effect of NOAF on mortality in critically ill COVID‐19 patients. Results NOAF incidence was 14.9% (n = 37), and 78% of patients (n = 29) were men in NOAF positive group. Median age of the NOAF group was 79.0 (interquartile range, 71.5‐84.0). Hospital mortality was higher in the NOAF group (87% vs 67%, respectively, P = .019). However, in multivariate analysis, NOAF was not an independent risk factor for hospital mortality (OR 1.42, 95% CI 0.40‐5.09, P = .582). Conclusions The incidence of NOAF was 14.9% in critically ill COVID‐19 patients. Hospital mortality was higher in the NOAF group. However, NOAF was not an independent risk factor for hospital mortality in patients with COVID‐19.

OBJECTIVE: To investigate the effects of two different rehabilitation programs in acute central vestibulopathy secondary to posterior circulation stroke. METHOD: A prospective randomized controlled study was conducted on 25 patients with posterior circulation stroke. Patients were instructed in routine balance and mobility exercises during the acute hospitalization period. At discharge, patients were assigned to either a rehabilitation or home exercise group. The home exercise group was instructed to perform the same exercise program provided in the course of hospitalization period. The rehabilitation group was randomized into the visual feedback posturography training or vestibular rehabilitation group. The balance and gait performance were assessed with clinical and objective measurements before and after 6 weeks of training. RESULTS: The balance and gait scores were significantly improved in both rehabilitation groups and in the home exercise group (p < 0.05), but no significant difference was found between the groups in terms of post-treatment values (p > 0.05). CONCLUSION: The improvements of balance and gait function in rehabilitation groups did not differ from the home exercise group. Rehabilitation programs were equally effective to improve the recovery in acute central vestibulopathy.
