Randomized Controlled Trial
Randomized clinical trial of angiotensin-converting enzyme inhibitor, ramipril, in patients with intermittent claudication.
The aim was to investigate the effect of ramipril on clinical parameters in patients with peripheral arterial disease. ⋯ NCT01037530 (http://www.clinicaltrials.gov).

Randomized Controlled Trial Comparative Study
Economic analysis of a randomized trial of percutaneous angioplasty, supervised exercise or combined treatment for intermittent claudication due to femoropopliteal arterial disease.
The aim was to compare costs and utilities of percutaneous transluminal angioplasty (PTA), a supervised exercise programme (SEP) and combined treatment (PTA + SEP) in patients with intermittent claudication (IC) to establish the most cost-effective treatment. ⋯ Supervised exercise is the most cost-effective first-line treatment for IC, and when combined with PTA is more cost-effective than PTA alone.

Multicenter Study
Multicentre observational study of performance variation in provision and outcome of emergency appendicectomy.
Identification of variation in practice is a key step towards standardization of service and determination of reliable quality markers. This study aimed to investigate variation in provision and outcome of emergency appendicectomy. ⋯ This study reveals the extremely wide variation in practice patterns and outcomes among hospitals. Organizational factors leading to this variation have been identified and should be addressed to improve performance.

Randomized Controlled Trial Comparative Study
Long-term clinical effectiveness of supervised exercise therapy versus endovascular revascularization for intermittent claudication from a randomized clinical trial.
Long-term comparisons of supervised exercise therapy (SET) and endovascular revascularization (ER) for patients with intermittent claudication are scarce. The long-term clinical effectiveness of SET and ER was assessed in patients from a randomized trial. ⋯ NTR199 (http://www.trialregister.nl).

Pancreatic fistula (PF) remains the most serious complication after digestive surgery. It is difficult to prevent because of the inability to visualize the leakage of pancreatic juice during surgery or to evaluate the protease activity of leaked fluid, which is responsible for PF formation. ⋯ The chymotrypsin probe enabled determination of the protease activity in drained pancreatic fluid samples and allowed real-time visualization of pancreatic juice leakage during surgery.
