Physical activity from the perspective of older adults: a convergent mixed-method study.

Background: Older adults are insufficiently physically active, despite its importance for healthy aging. To develop appropriate physical activity interventions, it is necessary to understand their physical activity. This study applies a theoretical perspective, the COM-B model, and a mixed-method design to examine what influences older adults' physical activity levels with three questions: (1) What individual and external factors predict older adults' physical activity levels? (2) What do older adults perceive as influencing their levels of physical activity? (3) To what extent do the quantitative results on older adults' physical activity levels agree and disagree with the qualitative findings on older adults' physical activity levels?

Methods: A convergent mixed-method design was used with questionnaire (n = 334) and interview (n = 14) data from adults 65 years and older.

Lifestyle, biological, and genetic factors related to brain iron accumulation across adulthood.

Iron is necessary for many neurobiological mechanisms, but its overaccumulation can be harmful. Factors triggering age-related brain iron accumulation remain largely unknown and longitudinal data are insufficient. We examined associations between brain iron load and accumulation and, blood markers of iron metabolism, cardiovascular health, lifestyle factors (smoking, alcohol use, physical activity, diet), and ApoE status using longitudinal data from the IronAge study (n = 208, age = 20-79, mean follow-up time = 2.

Benefits and risks of using laparoscopic ultrasonography versus intraoperative cholangiography during laparoscopic cholecystectomy for gallstone disease: a systematic review and meta-analysis.

Background: Intraoperative laparoscopic ultrasonography (LUS) or intraoperative cholangiography (IOC) can be used for visualisation of the biliary tract during laparoscopic cholecystectomy. The aim of this systematic review was to compare use of LUS with IOC.

Methods: PubMed, Embase, the Cochrane Library, and Web of Science were searched (last update: April 2024).

Understanding factors for adhering to health recommendations during COVID-19 among older adults - a qualitative interview study using health belief model as analytical framework.

Introduction: The COVID-19 pandemic has presented a unique possibility to broaden the understanding of people's reactions to a global crisis. Early on, it became evident that older adults were particularly vulnerable to the virus and that the actions of this age group would be crucial to the outcome. This qualitative interview study uses the Health Belief Model (HBM) framework as an analytical tool to examine older people's experiences of adherence to recommendations during the initial phase of the COVID-19 pandemic.

The anesthesiologist's guide to swine trauma physiology research: a report of two decades of experience from the experimental traumatology laboratory.

Purpose: Swine are one of the major animal species used in translational research, with unique advantages given the similar anatomic and physiologic characteristics as man, but the investigator needs to be familiar with important differences. This article targets clinical anesthesiologists who are proficient in human monitoring. We summarize our experience during the last two decades, with the aim to facilitate for clinical and non-clinical researchers to improve in porcine research.
