Phase angle is related to oxidative stress and antioxidant biomarkers in breast cancer patients undergoing chemotherapy.

Purpose: The study aimed to analyze the influence of chemotherapy on health biomarkers and examine the relationship between phase angle (PhA) and oxidative stress.

Methods: A prospective study was performed. Women who were starting chemotherapy were recruited.

Phase angle and cellular health: inflammation and oxidative damage.

Phase angle is a composite measure that combines two raw bioelectrical impedance analysis measures: resistance and reactance. Phase angle has been considered an indicator of cellular health, integrity, and hydration. As inflammation and oxidative stress can damage cellular structures, phase angle has potential utility in early detecting inflammatory and oxidative status.

An Evaluation of Metabolic, Dietetic, and Nutritional Status Reveals Impaired Nutritional Outcomes in Breast Cancer Patients.

Nutritional status can change in breast cancer patients after treatment. However, the metabolic implications of those alterations are poorly understood. We used a cross-sectional study design to compare body composition, lipids, glucose levels, and adiposity indices in breast cancer patients with a matched control and a healthy group.

Metabolic syndrome and unfavorable outcomes on body composition and in visceral adiposities indexes among early breast cancer women post-chemotherapy.

Purpose: The study objected to investigate potential changes in metabolic, dietary, and nutritional status in women with stages I-III breast cancer exposed to chemotherapy.

Methods: Women who were starting chemotherapy with no previous treatment were recruited. Anthropometrics, bioelectrical impedance analysis, handgrip strength, blood pressure and blood sample were collected.

Performance of functionality measures and phase angle in women exposed to chemotherapy for early breast cancer.

Purpose: The study aimed to analyze the influence of chemotherapy on nutritional status and the phase angle (PhA) as nutritional indicator for breast cancer women undergoing chemotherapy.

Methods: A prospective study was performed. Women who were starting chemotherapy with no previous chemotherapy treatment were recruited.

Cutoff Points of BMI for Classification of Nutritional Status Using Bioelectrical Impedance Analysis.

The objective of this study was to improve the cutoff points of the traditional classification of nutritional status and overweight / obesity based on the BMI in a Brazilian sample. A cross-sectional study was conducted on 1301 individuals of both genders aged 18 to 60 years. The subjects underwent measurement of weight and height and bioelectrical impedance analysis.

BMI, BMIfat, BAI or BAIFels - Which is the best adiposity index for the detection of excess weight?

Objective: To compare the diagnostic performance of adiposity indeces body mass index (BMI), body mass index adjusted for fat mass (BMIfat), body adiposity index (BAI) and body adiposity index for the Fels Longitudinal Study sample (BAIFels) and the overweight detection in a sample of the Brazilian population.

Methods: Cross-sectional study with 501 individuals (female/male = 387/114), which underwent anthropometric measurements and body composition for subsequent calculation of adiposity indices. Statistical analyzes considered p < 0.

Relationship Between Adiposity Indices, Lipodystrophy, and Sarcopenia in HIV-Positive Individuals With and Without Lipodystrophy.

Metabolism disorders, as well as body shape abnormalities, have been associated with the introduction of antiretroviral therapy. The objective of this study was to compare the diagnostic ability of adiposity indices and to discuss criteria for the classification of lipodystrophy and sarcopenia (SP) in HIV-positive individuals. Anthropometric measurements were determined in 268 individuals of both genders, also submitted to the dual-energy X-ray absorptiometry exam.

Application of body mass index adjusted for fat mass (BMIfat) obtained by bioelectrical impedance in adults.

Introduction: Body mass index (BMI) has been one of the methods most frequently used for diagnose obesity, but it isn't consider body composition.

Objective: This study intends to apply one new adiposity index, the BMI adjusted for fat mass (BMIfat) developed by Mialich et al. (2011), in a adult Brazilian sample.

Oxidative stress biomarker responses to an acute session of hypertrophy-resistance traditional interval training and circuit training.

We have studied circuit resistance schemes with high loads as a time-effective alternative to hypertrophy-traditional resistance training. However, the oxidative stress biomarker responses to high-load circuit training are unknown. The aim of the present study was to compare oxidative stress biomarker response with an acute session of hypertrophy-resistance circuit training and traditional interval training.
