Randomized Controlled Trial
Mental and physical fatigue-related biochemical alterations.
To confirm fatigue-related biochemical alterations, we measured various parameters just before and after relaxation and fatigue-inducing mental or physical sessions. ⋯ Some mental or physical fatigue-related biochemical changes were determined. Various biochemical alterations reflecting homeostatic perturbation and its responses might be shown. We believe that our results contribute to clarifying the mechanism of fatigue, developing evaluation methods, and establishing a basis for treatment.

Artificial nutrition (AN) is now considered medical therapy and has progressively become one of the mainstays of the different therapeutic options available for home or hospitalized patients, including surgical, medical, and critically ill patients. The clinical relevance of any therapy is based on its efficacy and effectiveness and thus on the improvement of its cost efficiency, i.e., the ability to provide benefits to the patients with minimal wasting of human and financial resources. The aim of the present study was to identify those indices, clinical, functional, or nutritional, that may reliably predict, before the start of AN, those patients who are likely not to benefit from nutritional support. ⋯ Proper prognostic instruments are necessary to perform optimal evaluations. The present study showed that a patient's general status (i.e., comorbidity, social quality of life, frailty) and nutritional and inflammatory statuses (i.e., lymphocyte count, albumin, prealbumin, C-reactive protein) have good predictive value on the effectiveness of AN.

Structured lipid emulsion improves the nitrogen balance and is rapidly cleared from the blood of moderately catabolic patients. However, the effects of structured lipids on inflammatory reactions during major surgery are not clear. This study investigated the effect of a parenteral structured triacylglycerol emulsion on leukocyte adhesion molecule expression and inflammatory mediator production in rats undergoing a total gastrectomy. ⋯ These results suggest that, compared with the LCT and MCT/LCT groups, rats administered STG had lower plasma lipid concentrations and leukocyte integrin expressions. In addition, STG administration may cause increased recruiting of neutrophils and monocytes at the site of injury and enhance antipathogenicity in rats undergoing a total gastrectomy.

Preoperative carbohydrate loading with clear fluids is thought to reduce surgery-related insulin resistance (IR). However, IR per se is already present in some patients scheduled for elective surgery. Data on the safety of preoperative oral carbohydrate loading in patients with IR undergoing surgery is lacking. We aimed to evaluate the effects of preoperative carbohydrate loading on the glucometabolic state and gastric content of patients with and without IR. ⋯ Patients with IR receiving a carbohydrate-rich drink before surgery appear not to be affected adversely by the beverage. Furthermore, they also obtain the probable beneficial effects related to these drinks and, like patients without IR, can undergo surgery safely.

Dietary caloric restriction (CR) has been found to reduce systemic markers of inflammation and may attenuate the effects of chronic inflammatory conditions. The purpose of this study was to examine the effects of long-term CR on naturally occurring chronic inflammatory periodontal disease in a nonhuman primate model. ⋯ Males demonstrated greater risk for naturally occurring periodontal disease than females. Long-term CR may differentially reduce the production of local inflammatory mediators and risk for inflammatory periodontal disease among males but not females.
