Multicenter Study
Non-interventional, retrospective data of long-term home parenteral nutrition in patients with benign diseases: Analysis of a nurse register (SERECARE).
The aim of this study was to evaluate the safety and efficacy of home parenteral nutrition (HPN) service in patients with benign chronic intestinal failure (CIF). ⋯ The use of a structured register has proved to be a key strategy for monitoring the outcomes of long-term treatment, improving time efficiency, and preventing potential malpractice. To our knowledge, this is the largest survey ever documented; the results were consistent despite the heterogeneity of the centers because of duly applied standard rules and protocols.

The aim of this study was to evaluate the effect of low doses of l-arginine supplementation on hemogram, integrity of DNA and spleen, inflammatory infiltrate in the jejunum, and in the coagulogram of rats submitted to 5-fluorouracil (5-FU) chemotherapy. ⋯ Supplementation with 100 mg/d of l-arginine minimized immunosuppression, spleen depletion, and prothrombin time and contributed to the breakdown of 5-FU-generated DNA in Wistar rats. Supplementation with 50 mg/d of l-arginine decreased the weight loss generated by 5-FU in Wistar rats. Supplements with 50 or 100 mg of l-arginine did not interfere with 5-FU-generated jejunal inflammatory infiltrate.

The loss of antioxidant protection from estrogen during menopause may lead to oxidative stress in the kidneys. Thus, antioxidant supplementation may potentially decrease the menopause-derived oxidative stress. The aim of this study was to evaluate the effect of α-lipoic acid (LA) and ω-3 long-chain polyunsaturated fatty acids on the redox profile of the kidneys in the ovariectomized rat model of menopause. ⋯ The results suggest that ovariectomy did not affect the redox profile in the kidneys. LA, DHA, and EPA supplementation increased certain endogenous antioxidants; however, EPA may have a prooxidant effect on the kidneys.

The aim of this study was to investigate the effects of creatine supplementation on early stages of ethanol-induced hepatic damage. ⋯ Creatine supplementation associated with ethanol is able to interfere in the alcohol metabolism and oxidative stress and to exacerbate ethanol-induced hepatic damage. These new findings are opposite to those observed in several studies where protective effects of creatine in a wide variety of injury models, including non-alcoholic fatty liver disease, were described.

The aim of this study was to investigate the effects of arachidonic acid (AA)-rich ARASCO oil on high-fat diet (HFD) + streptozotocin (STZ)-induced diabetes mellitus in male Wistar rats and its possible mechanisms of action. ⋯ These results suggest that ARASCO, a rich source of AA, can prevent HFD + STZ-induced diabetes in Wistar rats owing to its anti-inflammatory action. It remains to be seen whether ARASCO oil is useful in preventing or postponing the development of type 2 diabetes mellitus in humans.
