Phase-Germ Project: Muscle Mass and Phase Angle in Surgical Patient

Overview

Current nutritional diagnostic tools have serious limitations in certain groups of patients such as colon or ovarian cancer with high rates of overweight and obesity in which traditional anthropometric assessment is limited. The objective of the project is to establish a comprehensive nutritional assessment in surgical patients assessed in intensified recovery programs in Surgery at a national level, including new techniques aimed at measuring muscular and functional affection.

Current nutritional diagnostic tools have serious limitations in certain groups of patients such as colon or ovarian cancer with high rates of overweight and obesity in which traditional anthropometric assessment is limited with underdiagnosis of malnutrition and possible effect on therapeutic toxicity and other complications. The objective of the project is to establish a comprehensive nutritional assessment in surgical patients assessed in intensified recovery programs in Surgery at a national level, including new techniques aimed at measuring muscular and functional affection in order to make a more precise diagnosis and a better prediction of complications and morbidity and mortality. In this group of patients with moderate or severe malnutrition, it is important to evaluate new techniques aimed at nutritional assessment with assessment tools focused on the morpho-functional diagnosis of malnutrition. From a scientific point of view, the following nutritional assessment techniques are being incorporated: 1- BIOIMPEDANCIOMETRY: Non-invasive technique, relatively inexpensive and easily transportable. 2- MUSCLE ULTRASOUND: The application of ultrasound for the morphological and structural study of muscle mass is an emerging technique. 3- DYNAMOMETRY: Dynamometry is one of the 6 criteria that define malnutrition according to ASPEN. It is a very sensitive parameter. 4- FUNCTIONAL TESTS: The execution or performance tests consist of the development of a series of physical activities related to mobility, walking or balance. Their results are related to those of the scales that assess the Activities of Daily Living (IADL). The main OBJECTIVES of the study are: 1. To establish a record of the prevalence of malnutrition in the surgical area based on morpho-functional techniques (adapted GLIM criteria). 2. To evaluate the implementation of morpho-functional diagnostic tools in said area (Bioimpedanciometry, muscle ultrasound and dynamometry). 3. To correlate the clinical-prognostic aspects with the clinical situation of the patient (morbidity-mortality, adverse effects associated with the disease itself or with the treatment, adaptation of the therapeutic regimen, quality of life...) Design: Prospective observational study, following the usual clinical practice without altering the flow of visits to clinical nutrition clinics. Patients: Patients presenting with acute or chronic disease-related protein calorie malnutrition on outpatient follow-up treatment by a multimodal salvage surgery program. Variables: * Assessment of Nutritional Status: * Global Subjective Assessment (GSV) Questionnaire: ANNEX 2 * Current weight (measured or estimated), usual weight, weight for calculations (adjusted weight in obese, weight without edema in malnourished), height (measured or estimated), BMI (measured or estimated), arm circumference. * Electrical bioimpedance measurement (model (50khz) Akern BIA 101): The following data will be obtained: TBW (total body water, L), ECW (extracellular water, L), ICW (intracellular water, L), FFM (lean mass, Kg ), FM (fat mass, Kg), BCM (cell mass, Kg), ASMM (appendicular muscle mass, Kg), SMI (muscle mass index, Kg), Hydration %. * Electrical bioimpedance measurement (TANITA Model TBF-300): Fat mass, in percent, Lean mass, in kilograms, Total body water, in percent, Body mass index, basal metabolism. * Abdominal and muscle ultrasound (mindray z6 probe 7l4p): * Abdominal echo: total, superficial and pre-peritoneal adipose tissue. Muscle echo (measured in centimeters). * Muscle echo: Area, circumference, axes and adipose tissue (measured in centimeters) * Analytical parameters: A blood test will be requested which will include the following determinations: * Total cholesterol and triglycerides, in milligrams per deciliter. * C-reactive protein, in milligrams per deciliter. * Albumin, in grams per deciliter. * Prealbumin, in milligrams per deciliter. * Lymphocytes, in microliters, * Functional parameters: * Get Up and Go Test: "get up and go" test: The patient sits on a chair, tells him to get up (start of test and timing), walks 3 meters and sits back on the initial chair (end of timing). ). Interpretation: \< 20 seconds: normal, \> 20 seconds: increased risk of falling. * Jamar® type dynamometers are the most widely used in international studies and have various grip positions. Make 3 measurements with their subsequent average, measured in Kilograms. Data collection and analysis: Record of described variables were be included in an "on line"database available to all centers.
