Multicenter Study
Multicentre phase II trial of near-infrared imaging in elective colorectal surgery.
Decreasing anastomotic leak rates remain a major goal in colorectal surgery. Assessing intraoperative perfusion by indocyanine green (ICG) with near-infrared (NIR) visualization may assist in selection of intestinal transection level and subsequent anastomotic vascular sufficiency. This study examined the use of NIR-ICG imaging in colorectal surgery. ⋯ Routine NIR-ICG assessment in patients undergoing elective colorectal surgery is feasible. NIR-ICG use may change intraoperative decisions, which may lead to a reduction in anastomotic leak rates.

Clinical and imaging surveillance practices following endovascular aneurysm repair (EVAR) for intact abdominal aortic aneurysm (AAA) vary considerably and compliance with recommended lifelong surveillance is poor. The aim of this study was to develop a dynamic prognostic model to enable stratification of patients at risk of future secondary aortic rupture or the need for intervention to prevent rupture (rupture-preventing reintervention) to enable the development of personalized surveillance intervals. ⋯ Secondary sac growth is an important predictor of rupture or rupture-preventing reintervention to enable the development of personalized surveillance intervals. A dynamic prognostic model has the potential to tailor surveillance by identifying a large proportion of patients who may require less intensive follow-up.

Permanent hypoparathyroidism remains the most common adverse outcome after total thyroidectomy, but long-term effects of hypoparathyroidism are unknown. The aim was to investigate mortality in patients with permanent hypoparathyroidism after total thyroidectomy. ⋯ Permanent hypoparathyroidism after total thyroidectomy for benign disease is common and associated with an increased risk of death.

There has been renewed public interest in manned space exploration owing to novel initiatives by private and governmental bodies. Long-term goals include manned missions to, and potential colonization of, nearby planets. Travel distances and mission length required for these would render Earth-based treatment and telemedical solutions unfeasible. These issues present an anticipatory challenge to planners, and novel or adaptive medical technologies must therefore be devised to diagnose and treat the range of medical issues that future space travellers will encounter. ⋯ Potential surgical treatment modalities must consist of self-sufficient and adaptive technology, especially in the face of uncertain pathophysiological mechanisms and logistical concerns.

Randomized Controlled Trial
Cost-effectiveness of population-based vascular disease screening and intervention in men from the Viborg Vascular (VIVA) trial.
Population-based screening and intervention for abdominal aortic aneurysm, peripheral artery disease and hypertension was recently reported to reduce the relative risk of mortality among Danish men by 7 per cent. The aim of this study was to investigate the cost-effectiveness of vascular screening versus usual care (ad hoc primary care-based risk assessment) from a national health service perspective. ⋯ Vascular screening appears to be cost-effective and compares favourably with current screening programmes.
