The Effect of Fasting on Body Composition Assessment in Hospitalized Cancer Patients.

Guidelines for bioelectrical impedance analysis (BIA) recommend fasting before measurements, but how it affects the outcomes is unclear. This descriptive, before-and-after study examines the effect of fasting on BIA results and its impact on the diagnosis of malnutrition in hospitalized cancer patients. Fifty-three oncology patients (admitted in January-March 2020) were consecutively enrolled regardless of their nutritional status.

[Nutritional assessment and intervention in hospitalized cancer patients at risk of or with malnutrition: evaluation of the effect on anthropometric and body composition parameters].

Introduction: malnutrition is a common problem in cancer patients that worsens during hospitalization and is associated with increased morbidity and mortality, and impaired quality of life. Objectives: to describe the effect of implementing a nutritional assessment and support protocol on the nutritional status of hospitalized cancer patients. Methods: a prospective, cross-sectional, non-controlled, quasi-experimental study in cancer patients admitted to an oncology service consecutively regardless of their nutritional status between September 2019 and March 2020.
