Factors Associated With the Presence and Severity of Nutritional Impact Symptoms in Individuals With Head and Neck Cancer Before Treatment.

As head and neck cancer (HNC) affects regions directly related to the digestive tract, it is consistently associated with nutritional impact symptoms (NISs), which further reduce food intake and affect nutritional status. Early identification of patients with NIS can assist therapy. This is a cross-sectional study with HNC patients from a cancer reference hospital.

Omega-3 Supplementation and Nutritional Status in Patients with Pancreatic Neoplasms: A Systematic Review.

Objectives: The purpose of this study was to synthesize and evaluate the evidence regarding the effects of omega-3 supplementation on the nutritional status of pancreatic cancer patients.

Methods: A systematic review of clinical trials was conducted, adhering to the PRISMA Statement. MEDLINE/PubMed, EMBASE, CENTRAL Cochrane, Scopus, and Web of Science databases were searched up to 31 December 2022 without restrictions on the publication date or language.

Poor diet quality is associated with biochemical parameters of protein nutritional status after Roux-en-Y gastric bypass.

Objective: To assess diet quality and its association with body and biochemical parameters in patients who underwent Roux-en-Y gastric bypass (RYGB).

Methods: Prospective observational study with individuals of both sexes subjected to RYGB. Body composition, biochemical parameters, and diet quality were assessed before and six months after RYGB.

Dynamic Changes in Adiponectin and Resistin Drive Remission of Cardiometabolic Risk Biomarkers in Individuals with Obesity Following Bariatric Surgery.

The remission of obesity-related diseases following bariatric surgery appears to result from the reorganization of metabolic and hormonal pathways involving adipokines. This study aimed to investigate the relationship between changes in body adiposity and serum adipokine levels, as well as the association between variations in adiponectin or resistin levels and cardiometabolic risk blood biomarkers before and after Roux-en-Y gastric bypass. A longitudinal and prospective study was conducted with bariatric surgery patients.

Factors Associated with the Nutritional Status of Women with Non-Metastatic Breast Cancer in a Brazilian High Complexity Oncology Center.

Background: Breast cancer poses a significant public health concern owing to its high prevalence and the risk of mortality associated with delayed diagnosis and treatment. The aim of this study was to assess the nutritional status of women with non-metastatic breast cancer and to identify factors associated with it.

Methods: A cross-sectional observational study was conducted at a High Complexity Oncology Assistance Center in the southeast region of Brazil, with the aim of assessing the nutritional status in women undergoing treatment for stage I, II, or III breast cancer.

Conicity index as an indicator of abdominal obesity in individuals with chronic kidney disease on hemodialysis.

Background: The conicity index is indicated as a tool for assessing the nutritional status of renal individuals undergoing hemodialysis. Thus, this study aimed to estimate the prevalence of abdominal obesity using the conicity index in individuals with chronic kidney disease undergoing hemodialysis to verify its association with sociodemographic, clinical, and lifestyle factors.

Materials And Methods: This is a cross-sectional study with 941 individuals undergoing hemodialysis in a metropolitan area in southeastern Brazil.

A Higher Phase Angle Is Associated with Greater Metabolic Equivalents in Women 1 Year After Bariatric Surgery.

Background: Phase angle (PhA), proposed as an indicator of the number, integrity, and function of cells and evaluated in some clinical situations, decreases after bariatric surgery (BS). In contrast, higher values are found in physically active or exercising individuals. We therefore evaluated the influence of physical activity on PhA after BS.

Roux-en-Y Gastric Bypass and Sleeve Gastrectomy Differently Affect Oxidative Damage Markers and their Correlations with Body Parameters.

Background: Bariatric surgery improves oxidative damage, but little is known about the differences between Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). This study compared changes in lipid and protein oxidative damage markers and their correlations with body parameters of patients before and after RYGB or SG.

Methods: Body mass index (BMI), bioimpedance parameters, and biochemical parameters including lipid and protein oxidative damage markers were evaluated before and 6 months after surgery.

Bioimpedance phase angle is associated with serum transthyretin but not with prognostic inflammatory and nutritional index during follow-up of women submitted to bariatric surgery.

Background & Aims: Phase angle (PhA) has been used as a prognostic indicator in several clinical situations. However, the use of PhA as a prognostic tool in bariatric patients is less known. The aim of this study was to evaluate PhA as a prognostic index and its correlation with the prognostic inflammatory and nutritional index (PINI) during follow-up of women subjected to bariatric surgery.

Whey protein increases muscle weight gain through inhibition of oxidative effects induced by resistance exercise in rats.

Whey protein (WP) is known for its nutritional value and antioxidant properties. The aim of this study was to evaluate whether the antioxidant properties of WP could contribute to muscle weight gain in response to resistance exercise (RE). We hypothesized that WP ingestion could increase muscle weight gain in rats subjected to an RE program, through inhibition of oxidative effects induced by high-intensity RE.

Whey protein modifies gene expression related to protein metabolism affecting muscle weight in resistance-exercised rats.

Objective: The aim of this study was to evaluate the effects of resistance exercise on the mRNA expression of muscle mammalian target of rapamycin (mTOR), muscle-specific RING finger-1 (MuRF-1), and muscle atrophy F-box (MAFbx) in the presence or absence of whey protein ingestion. We hypothesized that resistance exercise in combination with whey protein ingestion alters the gene expression of proteins related to muscle protein synthesis (mTOR) and/or degradation (MuRF-1 and MAFbx), thus affecting muscle weight gain in rats.

Methods: Thirty-two male Fischer rats were randomly assigned to the following four experimental groups (n = 8/group): Control sedentary, control exercised, whey protein sedentary, and whey protein exercised.

Whey protein precludes lipid and protein oxidation and improves body weight gain in resistance-exercised rats.

Background: Resistance exercise such as weight-lifting (WL) increases oxidation products in plasma, but less is known regarding the effect of WL on oxidative damage to tissues. Dietary compounds are known to improve antioxidant defences. Whey protein (WP) is a source of protein in a variety of sport supplements and can enhance physical performance.

Evaluation of biological and biochemical quality of whey protein.

Nutritional and biochemical properties of noncommercial whey protein have been described since 1950. However, comparisons between commercial whey protein for human consumption and casein are rarely found. The aim of this study was to compare biological quality of a commercial whey protein with casein and its effect on biochemical parameters of rats.
