Randomized Controlled TrialEffects of Ramadan intermittent fasting on inflammatory and biochemical biomarkers in males with obesity.
To determine the effects of Ramadan intermittent fasting (RIF) on inflammatory (C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α)) and biochemical markers of liver-renal function (aspartate aminotransferase (AST), alanine amino transferase (ALT), bilirubin, lactate dehydrogenase (LDH), urea and creatinine) in males with obesity. ⋯ This study demonstrates that RIF improves systemic inflammation biomarkers in males with obesity. Moreover, RIF did not negatively affect biomarkers of liver and renal function.

Randomized Controlled TrialEffects of mental and physical orofacial training on pressure pain sensitivity and tongue strength: A single-blind randomized controlled trial.
The main objective of this study was to analyze differences on pain pressure thresholds, tongue strength and perceived effort between various orofacial motor exercise training dosages of mental representation training through motor imagery (MI) and action observation (AO), first in isolation and then in combination with real exercise performance. ⋯ The results of the present study suggest that movement representation training performed in isolation may have a positive effect on PPTs and tongue muscle strength. In addition, the combination with the actual execution of the exercises could be considered effective, but it is necessary to take into account the training dosage to avoid fatigue responses.

Randomized Controlled TrialEffect of green tea extract supplementation on exercise-induced delayed onset muscle soreness and muscular damage.
Previous studies addressed the antioxidant and anti-inflammatory role of compounds from green tea in different human tissues. Positive antioxidant and anti-inflammatory effects were described for brain tissues. Whether similar effects are observed in the skeletal muscle, green tea supplementation could be a strategy to reduce delayed onset muscle soreness resultant of exercise. ⋯ Plasma oxidative damage marker and antioxidant status did not show an effect of supplementation. As a conclusion, green tea extract supplementation did not reduce the sensation of delayed onset muscle soreness but reduces the marker of muscle damage after exercise. It suggests the green tea extract supplementation has positive effects on muscle recovery after strenuous exercise.

Randomized Controlled Trial Observational StudyFactors affecting acute pain perception and analgesics consumption in patients undergoing bariatric surgery.
Previous studies performed in non-obese patients undergoing elective surgery have revealed that psychological factors may affect postoperative analgesic requirements. The aim of this observational prospective study was to investigate the extent to which psychopathological dimensions, including anxiety, depression and alexithymia, may influence postoperative pain intensity and analgesics consumption using patient-controlled analgesia (PCA) in patients undergoing bariatric surgery. ⋯ Obese patients with high depression, anxiety and alexithymia levels rated their pain as more intense and required a larger amount of tramadol. Pain perception intensity was predicted by anxiety and depression but not by alexithymia, whereas analgesics consumption was predicted by all the investigated psychopathological dimensions.

Randomized Controlled TrialThe effects of caffeine ingestion on exercise-induced hypoalgesia: A pilot study.
Exercise acutely reduces pain sensitivity, termed exercise-induced hypoalgesia (EIH). The mechanisms underlying EIH remain unclear. Caffeine, a non-specific adenosine receptor antagonist has been shown to attenuate EIH in animals-suggesting the involvement of the adenosinergic system. ⋯ TPT increased from 46.2±2.9°C to 46.8±2.6°C (p=0.008) following the 15min exercise bout, but did not change (46.4±3.6°C vs. 46.8±3.3°C; p=0.24) following the shorter, higher intensity exercise bout. The results from this study indicate cycling exercise reduces pain sensitivity, especially to pressure stimuli. Caffeine ingestion did not alter the EIH response-suggesting adenosine may not play a prominent role in the EIH response in humans.
