Review Meta Analysis
Role of bariatric surgery in reducing the risk of colorectal cancer: a meta-analysis.
Obesity increases the risk of multiple co-morbidities such as type 2 diabetes, cardiovascular disease and most cancers, including colorectal cancer. Currently, the literature presents conflicting results regarding the protective effects of bariatric surgery on the incidence of colorectal cancer. This meta-analysis was conducted to investigate the effect of bariatric surgery on the risk of developing colorectal cancer in obese individuals. ⋯ Patients who underwent bariatric surgery had a greater than 35 per cent reduction in the risk of developing colorectal cancer compared with obese individuals who had no surgery.

Randomized Controlled Trial
Effect of footplate neuromuscular electrical stimulation on functional and quality-of-life parameters in patients with peripheral artery disease: pilot, and subsequent randomized clinical trial.
Supervised exercise programmes for intermittent claudication have poor access and limited compliance. Neuromuscular electrical stimulation (NMES) may be an effective alternative. A proof-of-concept study and RCT were conducted. ⋯ Footplate NMES significantly improved walking distance in patients with intermittent claudication when used independently and also as an adjunct to supervised exercise. Registration number: trial 1, NCT02436200; trial 2, NCT02429310 (http://www.clinicaltrials.gov).

Randomized Controlled Trial Comparative Study
Randomized clinical trial of intracorporeal versus extracorporeal anastomosis in laparoscopic right colectomy (IEA trial).
Several non-randomized and retrospective studies have suggested that intracorporeal anastomosis (IA) has advantages over extracorporeal anastomosis (EA) in laparoscopic right colectomy, but scientific evidence is lacking. The aim was to compare short-term outcomes and to define the possible benefits of IA compared with EA in elective laparoscopic right colectomy. ⋯ Duration of hospital stay was similar, but IA was associated with less pain and fewer complications. Registration number: NCT02667860 ( http://www.clinicaltrials.gov).

Pressure injuries (PIs) after surgery affect thousands of people worldwide. Their management is expensive, a cost that can be reduced with proper preventive measures. Patients having surgery under general anaesthesia are at risk of developing PI, yet no specific tool has been developed to assess the risk in these patients. This review aimed to summarize the published data on perioperative risk factors associated with the development of PI in adults having surgery under general anaesthesia. ⋯ Cardiovascular disease, respiratory disease, diabetes mellitus, anaemia and duration of surgery should be taken into consideration when trying to identify surgical patients at high risk of developing PIs. These factors could be used to predict PIs after surgery.

Observational Study
Validation of the Norwegian survival prediction model in trauma (NORMIT) in Swedish trauma populations.
Trauma survival prediction models can be used for quality assessment in trauma populations. The Norwegian survival prediction model in trauma (NORMIT) has been updated recently and validated internally (NORMIT 2). The aim of this observational study was to compare the accuracy of NORMIT 1 and 2 in two Swedish trauma populations. ⋯ NORMIT 2 is well suited to predict survival in a Swedish trauma centre population, irrespective of injury severity. Both NORMIT 1 and 2 performed poorly in a more heterogeneous national population of injured patients.
