Objective: Arterial sampling for PET imaging often involves continuously measuring the radiotracer activity concentration in blood using an automatic blood sampling system (ABSS). We proposed and validated an external delay and dispersion correction procedure needed when a change in flow rate occurs during data acquisition. We also measured the external dispersion constant of [11C]CURB, [18F]FDG, [18F]FEPPA, and [18F]SynVesT-1.

Older patients over age 65 with acute cholecystitis may face greater perioperative risk compared to younger patients undergoing urgent laparoscopic cholecystectomy. We aimed to characterize trends in utilization and outcomes of inpatient cholecystectomy across the United States stratified by age.

However, apart from occasional case reports, the human-biting ticks in Singapore have received little attention from researchers.

Indigenous Australians are disproportionately affected by diabetes, with a diagnosis rate nearly four times higher than people from a non-Indigenous background. This health disparity highlights the urgent need for healthcare providers to develop cultural empathy - a critical competency for delivering culturally safe and person-centered care. Cultural empathy is essential for building trust and effective communication in diabetes education and management within Indigenous people.
