Introduction Flexible intensive care unit (ICU) visiting hours have been proposed as a means to improve patient-centred and family-centred care. However, randomised trials evaluating the effects of flexible family visitation models (FFVMs) are scarce. This study aims compare effectiveness safety an FFVM versus restrictive model (RFVM) on delirium prevention among ICU patients, well analyse its potential members professionals.

Abstract BACKGROUND Nodules of the thyroid gland are observed frequently in patients who undergo ultrasound studies. The majority these nodules benign, corresponding to goiters or adenomas, and only a small fraction corresponds carcinomas. Among tumors, diagnosis follicular adenocarcinomas by preoperative fine‐needle aspiration biopsy is major challenge, because it requires inspection entire capsule differentiate from adenoma. Consequently, large numbers unnecessary thyroidectomy. METHODS...

To mitigate mortality among critically ill COVID-19 patients, both during their Intensive Care Unit (ICU) stay and following ICU discharge, it is crucial to measure its frequency, identify predictors establish an appropriate post-ICU follow-up strategy.In this multicentre, prospective cohort study, we included 586 patients.We observed overall of 20.1% [95%CI: 17.1% 23.6%] (118/586) hospital 25.4% 22.1% 29.1%] (149/586). For survivors, 30 days (early) was 5.3% 3.6% 7.8%] (25/468) one-year...
