Injury and illness among Norwegian Olympic athletes during preparation for five consecutive Summer and Winter Games.

Objective: To describe the patterns of health problems among Norwegian Olympic candidates during their preparations for five consecutive Olympic Games (London 2012, Sochi 2014, Rio de Janeiro 2016, PyeongChang 2018 and Tokyo 2020).

Methods: This was a descriptive epidemiological study using the Oslo Sports Trauma Research Center Questionnaire on Health Problems to collect data on all self-reported health problems from Norwegian Olympic candidate athletes for 12-18 months prior to each Olympic Games. Team physicians and physiotherapists followed up the athlete reports, providing clinical care and classifying reported problems according to the International Olympic Committee 2020 consensus statement on methods for recording and reporting of epidemiological data on injury and illness in sport.

Methods, challenges and benefits of a health monitoring programme for Norwegian Olympic and Paralympic athletes: the road from London 2012 to Tokyo 2020.

Objective: To describe the implementation of a health monitoring programme for Norwegian Paralympic and Olympic candidates over five consecutive Olympic and Paralympic Games cycles (London 2012, Sochi 2014, Rio de Janeiro 2016, PyeongChang 2018 and Tokyo 2020).

Methods: Athletes were monitored for 12-18 months preparing for the games using a weekly online questionnaire (OSTRC-H2) with follow-up by physicians and physiotherapists, who provided clinical care and classified reported problems.

Results: Between 2011 and 2020, 533 Olympic and 95 Paralympic athletes were included in the monitoring programme, with an overall response of 79% to the weekly questionnaire and a total observation period of 30 826 athlete weeks.

Leukocyte recruitment and expression of chemokines following different forms of vascular injury.

Unlabelled: Inflammation plays a central role in restenosis following coronary intervention. Recent human and animal data suggest important differences between the inflammatory responses to simple balloon angioplasty compared with stent implantation. To investigate the mechanisms of these differences, New Zealand white rabbits underwent bilateral iliac artery balloon denudation.

Low-risk percutaneous coronary interventions without on-site cardiac surgery: two years' observational experience and follow-up.

Background: We studied the safety and efficacy of performing low-risk elective and acute infarct percutaneous coronary interventions at a community hospital without cardiac surgical capability.

Methods: Immanuel St Joseph's Hospital is located 85 miles from St Mary's Hospital, which is the nearest center with on-site cardiac surgery. All components of the Mayo Clinic percutaneous coronary intervention program were replicated at Immanuel St Joseph's Hospital, including a telemedicine system to enable real-time consultation with interventional and cardiac surgical colleagues during procedures.

Design-Dependent Variations in Coronary Stent Stenosis Measured as Precisely by Angiography as by Histology.

BACKGROUND: Coronary stent restenosis is a growing clinical concern which, because restenosis may vary with stent design, requires a validated, accurate and sensitive method of evaluation as new stents are developed. Histologic analysis of arterial cross sections, a highly accurate tool in animal models, has limited applicability in humans. Quantitative coronary angiography, while commonly used in the clinical evaluation of coronary interventions, has a controversial role as an adequate measure of restenosis, and few studies have validated quantitative angiography in diseased arteries.
