Evidence suggests that ω-3 fatty acids (FA) may have an anabolic effect on skeletal muscle. However, questions about dosage, frequency, combined protein supplementation, or different physical exercises remain unanswered. The aim of this study was to quantify by stereology whether supplementation with high dosages of ω-3 FA combined with swimming has an anabolic effect on the skeletal musculature and on the lipid profile of rats. ⋯ The administration of high doses of ω-3 associated with physical activity may be beneficial in the treatment of dyslipidemia. High doses of ω-3 FA do not cause muscle mass alteration.

Bariatric surgery is becoming increasingly popular in the treatment of severely obese patients who failed to lose weight with the help of non-surgical interventions. Such patients are at increased risk for premature death, type 2 diabetes, high blood pressure, gallstones, coronary heart disease, dyslipidemia, some cancers, anxiety, depression, and degenerative joint disorders. Although bariatric surgery appears to be the most effective and durable treatment option for obesity, it is associated with a number of surgical and medical complications. ⋯ To achieve better surgery outcomes, a number of postsurgical strategies must be considered. The aim of this review was to describe possible complications, ailments, and important moments in the follow-up after bariatric surgery. Adequate lifelong monitoring is crucial for the achievement of long-lasting goals and reduction of post-bariatric complications.

Vegetables from the Cucurbitaceae family and their products: Positive effect on human health.
The Cucurbitaceae family is a large group of crops with more than 800 species known worldwide. Vegetables from this family have been used for centuries, not only for consumption, but also for their medicinal value. The most characteristic cucurbits are pumpkin and cucumber, which are cultivated and consumed in many parts of the world. ⋯ Cucurbit plants are rich in carotenoids, terpenoids, saponins, and phytochemicals. Vegetables from the Cucurbitaceae family have a positive influence on human health, and various studies have clearly indicated that cucurbit vegetables have antioxidant, antidiabetic, antiinflammatory, and purgative properties. This mini review evaluates the current literature about vegetables from the Cucurbitaceae family and their products, in addition to their positive effect on human health.

Weight loss has been validated as a prognostic predictor of nasopharyngeal carcinoma (NPC); however, no global unitary indicator and criteria exist for the definition of weight loss as a prognostic factor. The aim of this study was to determine the most effective indicator for weight loss, evaluate its effect on the prognosis of NPC, and further propose a cutoff value to identify patients in need of nutritional care. ⋯ PWL is a promising predictor for NPC, and cutoff values could be validated for nutritional risk grading in patients with NPC. These stratified criteria may help accelerate the extensive application of grading nutritional management in NPC therapy.

Resistance training combined with consumption of a high-protein diet (HPD) is typically recommended to increase muscle mass, as both acute resistance exercise (RE) and dietary protein intake stimulate mechanistic target of rapamycin complex 1 (mTORC1) and muscle protein synthesis (MPS). However, the effect of chronic HPD consumption on MPS response to an acute RE remains to be determined. ⋯ The present results suggested that although 4 wk of HPD reduces body fat and increases skeletal muscle mass, it does not affect muscle protein synthesis at basal state, and in response to acute RE.
