Morbidity and Mortality following Surgery for Hip Fractures in Elderly Patients.

Aim: To determine morbidity and mortality in elderly patients following hip fracture surgery in Egypt and its correlates and to determine the utility of the POSSUM scale to predict morbidity and mortality among our population.

Methodology: We assessed postoperative morbidity and mortality following hip fracture surgery in a 6-month prospective observational study of 100 elderly patients who were undergoing surgical repair at the beginning of the study. The exclusion criteria included surgically unfit patients and patients refusing to participate in the study.

Changes in glutamate decarboxylase enzyme activity and tau-protein phosphorylation in the hippocampus of old rats exposed to chronic mild stress: reversal with the neuronal nitric oxide synthase inhibitor 7-nitroindazole.

Effects of chronic stress are not completely understood. They may underlie depression and dementia. This study assessed the association between chronic stress, glutamate levels, tau-protein phosphorylation, and nitric-oxide in old rats exposed to chronic mild stress (CMS).
