- Brief Summary
Weight loss commonly occurs in patients with chronic heart failure (CHF) and chronic obstructive pulmonary disorder (COPD), negatively influencing their quality of life, treatment response and survival. Loss of muscle protein is generally a central component of weight loss in CHF and COPD patients, but patients also have reductions in fat mass and bone density, independent of the severity of the disease state. The purpose of this study is to provide detailed insight in disease related gut function by obtaining information on gut permeability, digestion and absorption of glucose, fat and protein in CHF and COPD patients compared to matched healthy controls. This will provide required information that is necessary to implement new strategies to develop optimal nutritional regimen in CHF and COPD.
- Detailed Description
General aims:
* To study the whole-body protein anabolic effect of several dosages of a high-quality protein sip feeding in COPD and CHF subjects as compared to healthy controls.
* To investigate the anabolic threshold in subjects with COPD and CHF as compared to healthy controls.
Purpose and objectives: Although the Researchers' previous study supports the concept of supplementing high-quality milk proteins in chronic wasting diseases i.e., COPD and CHF, the dose-response anabolic effects of proteins with high EAA levels are still unclear. Furthermore, there is no insight in the actual protein requirements in COPD and CHF. The knowledge gained from this study will benefit insight in terms of promotion of protein gain after feeding in COPD and CHF subjects. Based on the obtained data of protein behavior (protein kinetics) the Researchers will be able to further refine and personalize nutritional supplementation in COPD and CHF subjects in order to stop and even restore progressive muscle wasting.

- Primary Outcome Measures
Name Time Method Change in net whole-body protein synthesis 0, 2, 5, 10, 15, 20, 30, 40, 50, 60, 90, 120, 150, 180, 210, 225, 240, 260, 280, 300, 320, 340, 360 ± 5 min Change in whole-body protein synthesis rate after intake of meal
- Secondary Outcome Measures
Name Time Method Body Composition 15 minutes on screening or study day 1 Body composition as measured by Dual-Energy X-ray Absorptiometry
Skeletal muscle strength on study day 1 handgrip and kin-com 1-leg test
Group differences in state of mood as measured by the Hospital Anxiety and Depression Scale (HADS) Postabsorptive state during 3 hours and change after feeding on study day 1 a fourteen item self-assessment scale. Seven of the items related to anxiety and seven relate to depression. Each item on the questionnaire is scored from 0-3 and this means that a person can score between 0 (no symptoms) and 21 (severe symptoms) for either anxiety or depression.
Gut function In postabsorptive and prandial state every 20 minutes up to 6 hours before each sip feeding on study day Digestion of the stable tracers of amino acid
diet recall on study day 1 The subject is asked to recall in detail all the food and drink consumed during the 24 hours prior to the test day.
Respiratory muscle strength on study day 1 Maximum inhalation and exhalation pressure
Group differences in quality of life as measured by Short Form (36) Health Survey (SF36) Postabsorptive state during 3 hours and change after feeding on study day 1 self administered questionnaire that measures each of the following eight health concepts: Physical Functioning (PF); Role-Physical (RP); Bodily Pain (BP); General Health (GH); Vitality (VT); Social Functioning (SF); Role-Emotional (RE); Mental Health (MH) as well as a reported Health Transition item (HT).
Executive Function-Adolescent/Adult Sensory Profile (ASP): Postabsorptive state during 3 hours and change after feeding on study day 1 a standardized self-questionnaire that generates an individualized profile of sensory processing across four quadrants: low registration, sensation seeking, sensory sensitivity, and sensation avoiding.
Group differences in activity as measured by Physical Activity Scale for the Elderly (PASE) Postabsorptive state during 3 hours and change after feeding on study day 1 questionnaire is intended for use in an elderly population and focuses on 3 types of activities: leisure time activities, household activities and work-related activities.
Group differences in attention and executive functions as measured by Trail Making Test (TMT) Postabsorptive state during 3 hours and change after feeding on study day 1 n Part A, the examinee is instructed to connect a set of 25 circles with numbers as quickly as possible while maintaining accuracy. In Part B, the examinee is instructed to connect a set of 25 circles, alternating between numbers and letters, as quickly as possible while maintaining accuracy. Measures attentional resources and is a measure of the frontal lobe "executive" functions of visual search, set-switching and mental flexibility. The total time in seconds was reported for each measure.
Group differences in overall cognitive abilities as measured by Montreal Cognitive Assessment (MoCA) Postabsorptive state during 3 hours and change after feeding on study day 1 assesses several cognitive domains and is used for the screening of mild cognitive impairment. Total scores range from 0-30 with lower scores indicating decreased functioning.
Group differences in attention and executive functions as measured by Stroop Color-Word Test (SCWT), Postabsorptive state during 3 hours and change after feeding on study day 1 a word page with words printed in black ink, a color page with blocks printed in color, and a color-word page where the color and the word do not match. The examinee reads the words or names the ink colors as quickly as possible within a time limit. Measures selective attention and inhibitory control. The total time in seconds was reported for each trial.
Group differences in state of mood as measured by the Profile of Mood State (POMS) Postabsorptive state during 3 hours and change after feeding on study day 1 A psychological distress scale to measure mood disturbance in 6 domains - fatigue-inertia, vigor-activity, tension-anxiety, depression-dejection, anger-hostility, and confusion-bewilderment. Healthy populations take 3 to 7 minutes to complete, and others may take up a bit longer.
Group differences in attention and executive functions as measured by PASAT Postabsorptive state during 3 hours and change after feeding on study day 1 a measure of cognitive function that assesses auditory information processing speed and flexibility, as well as calculation ability.
Group differences in learning and memory as measured by Controlled Oral Word Association Test (COWAT), Postabsorptive state during 3 hours and change after feeding on study day 1 The examinee is required to say as many words as they can think of in one minute that begin with a given letter of the alphabet. The task contains three trials. Measures phonetic verbal fluency. The raw score (total and mean words recorded across the three trials) was reported.
Group differences in learning and memory as measured by Auditory Verbal Learning Test (AVLT) Postabsorptive state during 3 hours and change after feeding on study day 1 a verbal episodic memory test that evaluates a wide diversity of functions: short-term auditory-verbal memory, rate of learning, retention and recognition of information.
Group differences in attention and executive functions as measured by Brief-A Postabsorptive state during 3 hours and change after feeding on study day 1 a standardized self-report that captures views of an adult's executive functions or self-regulation in his or her everyday environment.
