Anesthesia and postoperative delirium in older adults undergoing hip surgery.

Objectives: To examine the effects of general anesthesia on the risk of incident postoperative delirium in older adults undergoing hip surgery.

Design: Secondary analysis of haloperidol prophylaxis for delirium clinical trial data. Predefined risk factors for delirium were assessed prior to surgery.

Diagnostic impact of CSF biomarkers in a local hospital memory clinic.

Background: CSF biomarkers amyloid-beta 1-42 (Abeta42), total tau (tau) and tau phosphorylated at threonine 181 (ptau-181) are useful diagnostic markers for Alzheimer's disease (AD). We examined the impact of these biomarkers in the diagnostic process in a non-academic memory clinic.

Methods: One hundred and nine patients with available CSF were included from the local hospital memory clinic.
