HIV-associated neurocognitive impairment in stable people living with HIV on ART in rural Tanzania.

Objectives: Few studies have assessed cognitive impairment among healthy people living with HIV (PLWH) who are stable on antiretroviral treatment (ART) in sub-Saharan Africa.

Methods: We conducted a cross-sectional study among a random sample of stable adult PLWH from rural Tanzania on ART for more than 1 year and without immunological failure or pre-existing neurological disease. We evaluated the prevalence and risk factors for neurocognitive impairment (NCI), assessed through neuropsychological tests, functional and depression questionnaires and defined as a mean Z-score ≤ -1 in two or more cognitive domains.

Reverse shoulder arthroplasty for acute proximal humeral fractures: Postoperative complications at 7 days, 90 days and 1 year.

Background: In the last decade, the biomechanics of reverse shoulder arthroplasty (RSA) for proximal humeral fractures in the elderly have led to more functional outcomes and greater pain relief. However, its use has also introduced a significant rate of complications. The purpose of this study is to assess the complication rate of RSA in these cases as well as the relationship to ASA score and basic disease history.

Effectiveness of feedback to physicians in reducing inappropriate use of hospitalization: a study in a Spanish hospital.

Objectives: To evaluate the effectiveness of feedback to medical staff in reducing inappropriate hospital days, particularly those attributable to conservative medical discharge policies.

Design: Quasi-experimental pre-test/post-test with non-equivalent control group.

Setting: A publicly funded hospital in industrial belt in Barcelona (Spain), serving a predominantly urban population of 100,000.
