Cataract surgery and IOP: a systematic review of randomised controlled trials.

Purpose: Cataract and glaucoma are two of the most common ocular comorbidities. Cataract surgery has been shown to influence intra-ocular pressure (IOP) in patients with glaucoma; nevertheless, the extent of this effect remains controversial, especially in patients with open-angle glaucoma (OAG). The aim of this review is to determine the real effect of cataract surgery on IOP change in patients with OAG, focusing on data retrieved from randomised controlled trials (RCTs).

Extensive right-sided infectious endocarditis due to .

is a rare cause of infectious endocarditis. Most cases have an acute and aggressive evolution, with a high mortality rate. We report the case of a 36-year-old man, with a history of unrepaired ventricular septal defect, who came to the emergency department with fever, cough and asthenia with 3 months of evolution.

Crossbreeding effects on growth and efficiency in beef cow-calf systems: evaluation of Angus, Caracu, Hereford and Nelore breed direct, maternal and heterosis effects.

The objective of this study was to determine breed additive and heterosis effects on growth curves, total milk yield (TMY), calf weaning weight (WW), predicted energy intake (EI), and cow efficiency (CE) of purebred and crossbred beef cows raised in Southern Brazil. The data were from 175 purebred and crossbred cows representing eight genetic groups: Angus (A), Hereford (H), Nelore (N), A × H (AH), H × A (HA), A × N (AN), N × A (NA), and Caracu (C) × A (CA). Growth of the cows was modeled using the nonlinear Brody function and machine milking was used to assess TMY.

Attention and working memory in elderly: the influence of a distracting environment.

The present work investigated the effect of a distracting environment in the performance of attentional and working memory (WM) tasks in elderly participants. To this end, forty elderly performed two attentional tasks (simple reaction time and go/no-go tasks), and three WM tasks (arithmetic, memory for digits and sequences of letters and numbers). Each participant performed the tasks in a distracting and a non-distracting environment, with an interval of 14-21 days between sessions.
