Low and moderate endurance exercise is associated with better control of cardiovascular risk factors, a decreased risk of coronary artery disease and atrial fibrillation (AF). There is, however, a growing proportion of individuals regularly performing strenuous and prolonged endurance exercise in which the health benefits have been challenged. Higher doses of endurance exercise have been associated with a greater coronary atherosclerotic plaque burden, risk of AF and myocardial fibrosis (MF).
Master@Heart is a multicentre prospective cohort study aiming to assess the incidence of coronary atherosclerosis, AF and MF in lifelong endurance athletes compared to late-onset endurance athletes (initiation of regular endurance exercise after the age of 30 years) and healthy non-athletes.The primary endpoint is the incidence of mixed coronary plaques. Secondary endpoints include coronary calcium scores, coronary stenosis >50%, the prevalence of calcified and soft plaques and AF and MF presence. Tertiary endpoints include ventricular arrhythmias, left and right ventricular function at rest and during exercise, arterial stiffness and carotid artery intima media thickness.Two hundred male lifelong athletes, 200 late-onset athletes and 200 healthy non-athletes aged 45-70 will undergo comprehensive cardiovascular phenotyping using CT, coronary angiography, echocardiography, cardiac MRI, 12-lead ECG, exercise ECG and 24-hour Holter monitoring at baseline. Follow-up will include online tracking of sports activities, telephone calls to assess clinical events and a 7-day ECG recording after 1 year.
Local ethics committees approved the Master@Heart study. The trial was launched on 18 October 2018, recruitment is complete and inclusions are ongoing.

The urgent need to recognise EHS symptoms to protect all attendees' health has considerably accelerated research examining the most effective cooling strategies and the development of wearable cooling technology and real-time temperature monitoring. While these technological advances will aid the early identification of EHS cases, there are several potential ethical considerations for governing bodies and sports organisers. For example, the impact of recently developed cooling wearables on health and performance is unknown. Concerning improving athletic performance in a hot environment, there is uncertainty about this technology's availability to all athletes. Furthermore, the real potential to obtain real-time core temperature data will oblige medical teams to make crucial decisions around their athletes continuing their competitions or withdraw. Therefore, the aim of this review is (1) to summarise the practical applications of the most novel cooling strategies/technologies for both safety (of athletes, spectators and workers) and performance purposes, and (2) to inform of the opportunities offered by recent technological developments for the early recognition and diagnosis of EHS. These opportunities are presented alongside several ethical dilemmas that require sports governing bodies to react by regulating the validity of recent technologies and their availability to all.Most marine ectotherms require the successful completion of a biphasic larval stage to recruit into adult populations. Recruitment of larvae into benthic habitats largely depends on biological interactions and favourable environmental conditions such as the inescapable diurnal thermal and tidal exposures. Hence, assessing how different taxa metabolically respond to variations in temperature is imperative to understand the community and ecosystem dynamics at both local and global scales. The present study aimed to investigate the effects of acute temperature variation on the physiology of stage-specific brachyuran larvae collected from different microhabitats at two mangrove forests in South Africa. Results indicate that the conditions within microhabitats, which larvae experience, likely influence their physiology, based on respirometry, to short-term acute temperature exposures. Furthermore, the larval thermal optimum shifted ontogenetically to become increasingly eurythermic as individuals developed from stage I zoea through to megalopa. Mangrove crab larvae in their early stages are hence increasingly vulnerable to acute temperature exposures, which could be particularly harmful to the persistence of populations if thermally stressful events increase in magnitude and frequency.Tracheobronchial injury is a rare, but potentially life-threatening condition, and in most cases requires urgent treatment to restore normal respiratory physiology. Over the past decades, extracorporeal membrane oxygenation (ECMO) has evolved as an important adjunct in airway surgery. We presented three cases of traumatic tracheobronchial injury managed with ECMO support at a level-1 trauma center and emphasized the benefits of anticipation and early institution of ECMO support perioperatively, in these high-risk cases. The management of traumatic tracheobronchial injuries requires early measures to guarantee adequate ventilation. Anticipation and early institution of ECMO in these patients may support respiratory physiology, facilitate repair and improve survival. The time factor and multidisciplinary communication and plan prior to intervention should be considered. LY2090314 ic50 ECMO support, whenever available, plays important role in the management of complicated tracheobronchial surgical procedure and thereby reduces risk of mortality.The number of robot-assisted thoracoscopic surgery (RATS) procedures performed for thoracic disease has been increasing. Recently, a narrow-profile vascular stapler (Signia small-diameter reload, Covidien Japan, Tokyo, Japan) has been developed to provide superior access and precise staple placement in video-assisted thoracoscopic surgery (VATS) procedures. A 70-year-old man who was an exsmoker visited our hospital with a complaint of coughing. Chest computed tomography revealed a tumor with a cavity, ~55 mm in diameter, in the right-middle lobe. A 4-arm RATS right-middle lobectomy was performed with a 4-cm utility thoracotomy with da Vinci Xi (Intuitive Surgical, Sunnyvale, CA, USA). The pulmonary vessels were divided using a narrow-profile vascular stapler through an 8-mm port. No complications occurred in the postoperative course. With a narrow-profile vascular stapler, portal RATS can be performed after VATS lung biopsy using 8-mm ports.
