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. Patients were assessed by the same dietician 24-48 h after admission, following the usual clinical practice. The measurements were taken after 12-h fasting (fasting state) and 60-90 min after breakfast (non-fasting state). Bioimpedance parameters (resistance [R], reactance [Xc], phase angle [PA]) and body composition indices (free-fat mass index [FFMI] and appendicular skeletal muscle index [ASMI]) were calculated. On average, R values did not significantly differ between fasting and non-fasting states (mean difference: +1.82 Ω; p = 0.64). The non-fasting Xc and PA were reduced (mean differences: -1.55 Ω, p = 0.93 and 0.09°, p = 0.82, respectively). Fasting and non-fasting FFMI and ASMI were similar (mean differences: -0.13 kg/m2 (p = 0.5) and -0.10 kg/m2 (p not calculated)). These results suggest that BIA does not require fasting, facilitating its routine use in hospitalized cancer patients.

Ultrasound Cut-Off Values for Rectus Femoris for Detecting Sarcopenia in Patients with Nutritional Risk.

BACKGROUND: A nationwide, prospective, multicenter, cohort study (the Disease-Related caloric-protein malnutrition EChOgraphy (DRECO) study) was designed to assess the usefulness of ultrasound of the rectus femoris for detecting sarcopenia in hospitalized patients at risk of malnutrition and to define cut-off values of ultrasound measures. METHODS: Patients at risk of malnutrition according to the Malnutrition Universal Screening Tool (MUST) underwent handgrip dynamometry, bioelectrical impedance analysis (BIA), a Timed Up and Go (TUG) test, and rectus femoris ultrasound studies. European Working Group on Sarcopenia in Older People (EWGSOP2) criteria were used to define categories of sarcopenia (at risk, probable, confirmed, severe). Receiver operating characteristic (ROC) and area under the curve (AUC) analyses were used to determine the optimal diagnostic sensitivity, specificity, and predictive values of cut-off points of the ultrasound measures for the detection of risk of sarcopenia and probable, confirmed, and severe sarcopenia. RESULTS: A total of 1000 subjects were included and 991 of them (58.9% men, mean age 58.5 years) were evaluated. Risk of sarcopenia was detected in 9.6% patients, probable sarcopenia in 14%, confirmed sarcopenia in 9.7%, and severe sarcopenia in 3.9%, with significant differences in the distribution of groups between men and women (p < 0.0001). The cross-sectional area (CSA) of the rectus femoris showed a significantly positive correlation with body cell mass of BIA and handgrip strength, and a significant negative correlation with TUG. Cut-off values were similar within each category of sarcopenia, ranging between 2.40 cm2 and 3.66 cm2 for CSA, 32.57 mm and 40.21 mm for the X-axis, and 7.85 mm and 10.4 mm for the Y-axis. In general, these cut-off values showed high sensitivities, particularly for the categories of confirmed and severe sarcopenia, with male patients also showing better sensitivities than women. CONCLUSIONS: Sarcopenia in hospitalized patients at risk of malnutrition was high. Cut-off values for the better sensitivities and specificities of ultrasound measures of the rectus femoris are established. The use of ultrasound of the rectus femoris could be used for the prediction of sarcopenia and be useful to integrate nutritional study into real clinical practice.

[Nutritional assessment and intervention in hospitalized cancer patients at risk of or with malnutrition: evaluation of the effect on anthropometric and body composition parameters]. / Valoración e intervención nutricional en pacientes oncológicos hospitalizados en riesgo de desnutrición o con desnutrición: evaluación del efecto sobre parámetros antropométricos y de composición corporal.

Introduction: 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. Anthropometric parameters, body composition, and hand grip strength were measured at admission and discharge. The percentage of patients with malnutrition, dynapenia, and sarcopenia at admission and discharge was calculated. Results: a total of 90 cancer patients participated in this study (mean age: 66 years, 67.8 % men); 33.2 % of the patients had a tumor in the gastrointestinal tract and 73.3 % of the patients were in stage IV; 95 % required nutritional support (nutritional supplementation, enteral nutrition or parenteral nutrition). After the nutritional intervention, no differences were found in the anthropometric parameters with a mean weight loss of 0.1, although improvements in body composition were observed. The percentage of malnourished patients remained stable on admission and discharge regardless of the criteria used. Conclusions: the implementation of a protocol for assessment and nutritional support at admission in cancer patients may help prevent or delay the worsening of their nutritional status during hospital stay.

Introducción: Introducción: la desnutrición es un problema frecuente en los pacientes oncológicos que empeora durante la hospitalización y se asocia con mayor morbimortalidad y deterioro de la calidad de vida. Objetivos: describir el efecto de la implantación de un protocolo de valoración y soporte nutricional sobre el estado nutricional de pacientes oncológicos hospitalizados. Métodos: estudio prospectivo, no controlado y cuasiexperimental en pacientes oncológicos ingresados en un servicio de oncología de forma consecutiva, independientemente de su estado nutricional, entre septiembre de 2019 y marzo de 2020. Se determinaron los parámetros antropométricos, la composición corporal y la fuerza prensora de la mano al ingreso y al alta. Se calculó el porcentaje de pacientes con desnutrición, dinapenia y sarcopenia al ingreso y al alta. Resultados: un total de 90 pacientes oncológicos participaron en este estudio (edad media: 66 años, 67,8 % hombres). El 33,2 % de los pacientes presentaban un tumor en el tracto gastrointestinal y el 73,3 % de los pacientes se encontraban en estadio IV. El 95 % necesitaron soporte nutricional (suplementación nutricional, nutrición enteral o nutrición parenteral). Tras la intervención nutricional no se encontraron diferencias en los parámetros antropométricos, con una pérdida de peso media de 0,1, aunque se observaron mejorías en la composición corporal. El porcentaje de pacientes desnutridos se mantuvo estable al ingreso y al alta independientemente del criterio empleado Conclusiones: la implementación de un protocolo de valoración y soporte nutricional al ingreso en pacientes oncológicos puede ayudar a evitar o retrasar el empeoramiento de su estado nutricional durante la hospitalización.

Relation of Malnutrition and Nosocomical Infections in Cancer Patients in Hospital: An Observational Study.

Aim: To investigate the relation between malnutrition and nosocomial infections (NI) in hospitalized cancer patients. Methods: This observational, cross-sectional, noninterventional, descriptive study was conducted in a 500-bed university hospital in Valencia (Spain). Adult cancer patients admitted to the oncology ward were consecutively enrolled regardless of their nutritional status between November 2019 and March 2020. Patients were nutritionally assessed 24 to 48 hours after admission. Body weight, height and BMI, body composition through measurement of bioelectrical impedance analysis (BIA), and muscle strength and functionality using hand grip strength (HGS) were prospectively collected. The diagnosis of malnutrition and sarcopenia was assessed using the Global Leadership Initiative on Malnutrition (GLIM) criteria and the European Working Group on Sarcopenia in Older People (EWGSOP) criteria, respectively. Patients were followed up during their hospital stay or outpatient oncology visits to identify possible NI. Results: A total of 107 patients were included in this study (mean age 66 years; 66.4% were men). The most frequent reason for admission was cancer treatment (19.6%), followed by infections (18.7%) and digestive tract symptoms (18.7%). Overall, 77.5% (83/107) of the patients were malnourished at admission according to the GLIM criteria, while 52.3% (56/107) were sarcopenic. Nosocomial infections (NI) were significantly more frequent in malnourished (52.1%; 25/48) and severely malnourished (42.1%; 8/19) patients, compared with well-nourished patients without malnutrition (25%; 10/40; p=0.035). The mean length of hospital stay was 13.9 days, significantly longer in patients with an NI compared to those without infections (18.6 vs. 10.8 days, p < 0.024). Conclusion: This study evidenced the need to implement a routine protocol for the nutritional assessment and support of cancer patients at risk of malnutrition and sarcopenia to reduce the risk of NI during their hospital stay.
