Effect of melatonin on postoperative cognitive function in elderly patients submitted to transurethral resection of the prostate under spinal anesthesia.

Background: Hospitalization for Transurethral Prostate Resection (TURP) involves circadian rhythm disturbance - a possible cause of Postoperative Neurocognitive Disorder (POCD) in elderly patients. This study investigated whether melatonin ameliorated this effect.

Methods: A double-blind, randomized clinical trial used a battery of neuropsychological tests to evaluate cognitive performance of 118 patients aged ≥ 60, before TURP with spinal anesthesia, and at 21- and 180-days PO.

Quality and readability of online information on Keratoconus in Portugal and Brazil.

Introduction: Keratoconus patients turn to the internet for answers to their disease expectations. Webpages are not filtered or submitted to evaluation before getting published. We aim to evaluate the quality and readability of the online information regarding keratoconus in Portugal and Brazil.

Laboratory profiles of patients hospitalized with COVID-19 pneumonia treated with tofacitinib or placebo: a post hoc analysis from the STOP-COVID trial.

Objective: Tofacitinib, an oral Janus kinase inhibitor, has been tested against a placebo in 289 patients with COVID-19 pneumonia. We analyzed the data from the tofacitinib- and placebo-treated patient cohorts to evaluate the laboratory profiles between baseline and day 7.

Methods: We performed post hoc analyses on the following laboratory tests over time during the first 7 days after randomization: hemoglobin, leukocytes, neutrophils, lymphocytes, platelets, alanine aminotransferase, and aspartate aminotransferase.

"Minho Technique" for Laparoscopic Radical Cystectomy with Intracorporeal Ileal Conduit.

Objective: Radical cystectomy (RC) with ileal conduit (IC) remains a main treatment for muscle-invasive bladder cancer (MIBC). Laparoscopy in this multistage surgery is quite demanding, so laparoscopic RC (LRC) with intracorporeal IC (IIC) is a technically exceptional procedure. We aim to simplify it, demonstrating our technique, step-by-step.

Pathogenicity of CsRV2 and CdPBV1 in Callinectes danae: An Imminent Concern for Crab Production in Brazil.

Understanding the pathogenicity of viral infections in aquatic organisms is vital due to their substantial impact on aquaculture and wild populations. This study assessed the pathogenicity of Callinectes sapidus Reovirus 2 in Callinectes danae and its effects on the metabolic, immunological and behavioural parameters. CsRV2-negative specimens were divided into CsRV2 inoculum (n = 10) and saline injection (n = 15).
