Preoperative hypoxic biomarkers and postoperative delirium in patients with obstructive sleep apnea.

Purpose: Postoperative delirium (POD) in patients with obstructive sleep apnea (OSA) is associated with increased mortality and healthcare costs. In this study, we investigated the association of OSA risk, serum biomarkers for central nervous ischemia (S100B and NSE), and POD.

Methods: After research ethics approval, patients completed the STOP BANG assessment before undergoing elective surgery.

Cognitive function in older patients and their stress challenge using different anesthesia regimes: a single center observational study.

Background: With increasing age older patients are at higher risk for cognitive decline after surgery. Even tailored anesthesia procedures in older patients remain a high risk for postoperative cognitive disorder. Additional stress derived from anxiety and anesthesia itself can negatively impact postoperative cognitive outcomes.

Social support as a buffer for perceived unfair treatment among Filipino Americans: differences between San Francisco and Honolulu.

Objectives: We examined whether perceived unfair treatment is associated with health conditions, whether social support moderates this association, and whether such relationships differ by location.

Methods: Data were derived from the 1998-1999 Filipino American Community Epidemiological Study, a cross-sectional investigation of 2241 Filipino Americans living in San Francisco and Honolulu. Negative binomial regression was used to examine potential 2-way and 3-way interactions between support, unfair treatment, and city (San Francisco vs Honolulu).
