Review Comparative Study
Systematic review of active surveillance versus surgical management of asymptomatic small non-functioning pancreatic neuroendocrine neoplasms.
The incidence of asymptomatic, sporadic, small non-functioning pancreatic neuroendocrine neoplasms (NF-PNENs) has increased in recent decades. Conservative treatment has been advocated for these tumours. The aim of this study was systematically to evaluate the literature on active surveillance and to compare this with surgical management for asymptomatic sporadic small NF-PNENs. ⋯ This systematic review suggests that active surveillance of patients affected by sporadic, small, asymptomatic NF-PNENs may be a good alternative to surgical treatment.

Staphylococcus aureus surgical-site infections (SSIs) are a major cause of poor health outcomes, including mortality, across surgical specialties. Despite current advances as a result of preventive interventions, the disease burden of S. aureus SSI remains high, and increasing antibiotic resistance continues to be a concern. Prophylactic S. aureus vaccines may represent an opportunity to prevent SSI. ⋯ There is an unmet medical need for novel S. aureus SSI prevention measures. Advances in understanding of S. aureus SSI pathophysiology could lead to the development of effective and safe prophylactic multiple-antigen vaccines to prevent S. aureus SSI.

Surgical-site infection (SSI) is still the second most common healthcare-associated infection, after respiratory tract infection. SSIs are associated with higher morbidity and mortality rates, and result in enormous healthcare costs. In the past decade, several guidelines have been developed that aim to reduce the incidence of SSI. Unfortunately, there is no consensus amongst the guidelines, and some are already outdated. This review discusses the recent literature regarding alternatives to antibiotics for prevention of SSI. ⋯ There is a general lack of evidence on the preventive effectiveness of perioperative measures to reduce the incidence of SSI. Most measures are based on common practice and perceived effectiveness. The lack of clinical evidence, together with the stability of the high incidence of SSI (10 per cent for colorectal procedures) in recent decades, highlights the need for future research.

Standard setting allows educators to create benchmarks that distinguish between those who pass and those who fail an assessment. It can also be used to create standards in clinical and simulated procedural skill. The objective of this review was to perform a systematic review of the literature using absolute standard-setting methodology to create benchmarks in technical performance. ⋯ Absolute standard-setting methodologies can be used to establish cut-offs for procedural skill assessments.

Randomized Controlled Trial
Long-term outcomes of a randomized clinical trial of supervised exercise, percutaneous transluminal angioplasty or combined treatment for patients with intermittent claudication due to femoropopliteal disease.
The aim was to compare the long-term outcomes of percutaneous transluminal angioplasty (PTA), a supervised exercise programme (SEP) and combined treatment (PTA + SEP) in patients with intermittent claudication owing to femoropopliteal disease. ⋯ PTA, SEP and combined treatment were equally effective long-term treatment options for patients with claudication owing to femoropopliteal disease. The addition of a SEP to PTA can reduce the rate of symptomatic restenosis and reintervention. Registration number: NCT00798850 (http://www.clinicaltrials.gov).
