Fish oil decreases the severity of treatment-related adverse events in gastrointestinal cancer patients undergoing chemotherapy: A randomized, placebo-controlled, triple-blind clinical trial.

Background And Aims: Due to its high peroxidizable characteristics, n-3 fatty acids, present in fish oil, could increase tumor cells sensitivity to conventional cancer treatment while non-neoplastic cells remain unaffected, this may lead to an increase in cancer treatment response with no increase on adverse effects. The aim of this study was to evaluate anti-cancer treatment response, performance status and adverse events in gastrointestinal cancer patients supplemented with fish oil. Oxidative stress parameters were investigated in blood non-neoplastic cells as an indicator of cytotoxicity.

Nutrition Risk Screening in Patients Admitted to an Adult Emergency Department of a Brazilian University Hospital.

Background: The prevalence of malnutrition in emergency units is high, and data on the nutrition risk of patients admitted in these units are scarce. The aims of this study are to determine the nutrition risk profile of individuals admitted in an emergency unit and to identify clinical, anthropometric, and laboratory attributes according to nutrition risk classification.

Materials And Methods: A total of 234 individuals in an emergency unit from 1 university hospital in Brazil were enrolled in this cross-sectional study.

Effects of mate tea consumption on muscle strength and oxidative stress markers after eccentric exercise.

Dietary phytochemical supplementation may improve muscle recovery from exercise. In this study, we investigated the effect of mate tea (MT) consumption - a phenol-rich beverage - on muscle strength and oxidative stress biomarkers after eccentric exercise. In a randomised, cross-over design, twelve men were assigned to drink either MT or water (control; CON) for 11 d.

Fish oil supplementation during chemotherapy increases posterior time to tumor progression in colorectal cancer.

The authors evaluated clinical outcomes during and after chemotherapy in colorectal cancer patients supplemented with fish oil during the first 9 wk of treatment. Thirty individuals never submitted to chemotherapy were randomized into supplemented group (SG), which received 2 g/day of fish oil (0.6 g/day of EPA and DHA) for 9 wk or control group (CG), which received neither fish oil nor placebo.

Individuals with hematological malignancies before undergoing chemotherapy present oxidative stress parameters and acute phase proteins correlated with nutritional status.

Hematological malignancies present abnormal blood cells that may have altered functions. This study aimed to evaluate nutritional status, acute phase proteins, parameters of cell's functionality, and oxidative stress of patients with hematological malignancies, providing a representation of these variables at diagnosis, comparisons between leukemias and lymphomas and establishing correlations. Nutritional status, C-reactive protein (CRP), albumin, phagocytic capacity and superoxide anion production of mononuclear cells, lipid peroxidation and catalase activity in plasma were evaluated in 16 untreated subjects.

Relationship between acute phase proteins and serum fatty acid composition in morbidly obese patients.

Background: Obesity is considered a low-grade inflammatory state and has been associated with increased acute phase proteins as well as changes in serum fatty acids. Few studies have assessed associations between acute phase proteins and serum fatty acids in morbidly obese patients.

Objective: To investigate the relationship between acute phase proteins (C-Reactive Protein, Orosomucoid, and Albumin) and serum fatty acids in morbidly obese patients.

Fish oil decreases C-reactive protein/albumin ratio improving nutritional prognosis and plasma fatty acid profile in colorectal cancer patients.

Previous studies have shown that n-3 polyunsaturated fatty acids n-3 (n-3 PUFA) have several anticancer effects, especially attributed to their ability to modulate a variety of genomic and immune responses. In this context, this randomized, prospective, controlled clinical trial was conducted in order to check whether supplementation of 2 g/day of fish oil for 9 weeks alters the production of inflammatory markers, the plasma fatty acid profile and the nutritional status in patients with colorectal cancer (CRC). Eleven adults with CRC in chemotherapy were randomized into two groups: (a) supplemented (SG) daily with 2 g/day of encapsulated fish oil [providing 600 mg/day of eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA)] for 9 weeks (n = 6), and (b) control (CG) (n = 5).

Effects of omega-3 fatty acids on regulatory T cells in hematologic neoplasms.

The development of leukemia and lymphomas is related to the increase in inflammatory process modulators. These, in turn, have divergent actions on the neoplastic process. Populations of T cells have different roles in the neoplastic environment; while interferon-gamma positive T cells have antitumor activity, the FoxP3+interleukin-10 positive population present a pro-tumor activity.
