Randomized Controlled Trial
Oxycodone vs. fentanyl patient-controlled analgesia after laparoscopic cholecystectomy.
Oxycodone is semi-synthetic opioid, oral and parenteral preparations have been widely used for acute and chronic pain. The aim of this study was to assess the efficacy and side effects of oxycodone and fentanyl in patient controlled analgesia (PCA) after laparoscopic cholecystectomy. ⋯ Oxycodone showed comparable effects for pain relief compared to fentanyl in spite of less cumulative PCA dose. Based on these results, we could conclude that oxycodone may be useful as an alternative to fentanyl for PCA after laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative Study
A comparative clinical study on five types of compression therapy in patients with venous leg ulcers.
The aim of this study was to compare five types of compression therapy in venous leg ulcers (intermittent pneumatic vs. stockings vs. multi layer vs. two layer short stretch bandages vs. Unna boots). Primary study endpoints were analysis of changes of the total ulcer surface area, volume and linear dimensions inside observed groups. ⋯ Significantly much worse rate found in group D (two layer short stretch bandages) - only 16.66%, 5/30 patients and E (Unna boots) - 20%, 6/30 patients. The analysis of changes of the percentage of Gilman index and wound total surface area confirmed that intermittent pneumatic compression, stockings and multi layer bandages are the most efficient. The two layer short - stretch bandages and Unna boots appeared again much less effective.

Randomized Controlled Trial
Effects of a pre-workout supplement on lean mass, muscular performance, subjective workout experience and biomarkers of safety.
In this prospective, randomized, double-blind, trial conducted in two parts, we examined the effects of a multi-ingredient pre-exercise workout supplement blend of creatine, betaine and a dendrobium extract (MMP) on safety, performance, and body composition in healthy men and women undergoing a supervised program of resistance exercise. Part 1 was an acute hemodynamic safety study wherein forty young, healthy men and women (26.2 ± 5.3 years, 70.4 ± 3.3 inches, 83.7 ± 14.9 kg, 26.0 ± 3.2 kg●m(-2)) ingest one dose of either the MMP or comparator in a randomized, double-blind, comparator controlled, crossover fashion before having their resting heart rate, blood, ECG and comprehensive blood chemistry and blood counts completed. Systolic (SBP) and diastolic (DBP) blood pressures were generally raised (3.0-5.4 mm Hg, p<0.01) following supplementation with MPP whereas in the comparator group SBP was marginally reduced by 0.3 to 1.2 mm Hg, p>0.05 at all time points) and DBP was increased (3.0 - 3.9 mm Hg, p<0.05 at all time points). ⋯ Self-reported scores for energy and concentration were significantly greater. Over a six-week training and supplementation period, MPP use was not associated with improvements in performance or body composition. Future studies should confirm these effects over a more prolonged training period.

Randomized Controlled Trial
Ondansetron does not attenuate the analgesic efficacy of nefopam.
The aim of this study was to investigate if there is any interaction between ondansetron and nefopam when they are continuously co-administrated during patient-controlled intravenous analgesia (PCIA). ⋯ Nefopam-plus-ondansetron is not inferior to nefopam alone in relieving the pain in PCIA after minimally invasive surgery. In addition, adverse events are reduced without compromising analgesic efficacy.

Randomized Controlled Trial
Creatine metabolism and safety profiles after six-week oral guanidinoacetic acid administration in healthy humans.
Guanidinoacetic acid (GAA) is a natural precursor of creatine, yet the potential use of GAA as a nutritional additive for restoring creatine availability in humans has been limited by unclear efficacy and safety after exogenous GAA administration. The present study evaluated the effects of orally administered GAA on serum and urinary GAA, creatine and creatinine concentration, and on the occurrence of adverse events in healthy humans. ⋯ Exogenous GAA is metabolized to creatine, resulting in a significant increase of fasting serum creatine after intervention. GAA had an acceptable side-effects profile with a low incidence of biochemical abnormalities.
