Successful Aging and Frailty

Frailty is the term commonly utilized to describe the geriatric syndrome that exposes the elderly to increased risk of negative health-related events. The frailty phenotypes (PF: physical or CF: cognitive) have demonstrated to predict the major negative health-related outcomes in the old population and show extensive similarities with sarcopenia (for PF) or dementia (for CF). However, the role of neurophysiological and biological factors contributing to the physical and cognitive frail condition, and in particular in which way mitochondrial dysfunction, as well as the hypertrophic and atrophic pathways assessed by genes expression, metabolomics and microbiota composition are contributing to these frail conditions, are still under debate. Therefore, the aim of this trial will be to make evidence based on the behaviors and the strategies that promote healthy lifestyle and successful human aging.

Effect of Incorporating Lean Beef Into a Protein-rich Diet During Resistance Training on Muscle and Tendon Strength in Older Women

Loss of muscle mass and strength is a well-established outcome of normal aging. Muscle strength and mobility are also dependent on the quality and strength of connective tissue, which surrounds skeletal muscle. These layers, which are continuous with tendons, allow for the effective transfer of tension from skeletal muscle to bone to enable movement. Importantly, skeletal muscle strength is directly related to connective tissue strength. Greater tendon connective tissue cross-sectional area and stiffness optimize force transfer through tendon to maximize musculoskeletal function. As with skeletal muscle, tendon connective tissue quality declines with age. Previous research indicates that resistance training can improve muscle strength in older adults, but may not counter the effects of aging on tendon. The specific problem is that no approaches are available that benefit both skeletal muscle and tendon health to minimize loss of muscle mass and quality while also improving connective tissue quality and function in older adults. A critical need exists to assess approaches that improve both muscle and connective tissue strength and function. This need is highly relevant for older women, due to their higher risk of sarcopenia than men. Resistance training, especially when combined with higher protein intake, has been consistently shown to improve muscle mass and strength in older adults. Further, emerging research indicates that diets rich in total and indispensable amino acids (as in beef) augment exercise-induced improvements in tendon cross-sectional area in rodents and young humans. However, limited research exists on the impact of beef consumption combined with resistance training on muscle and tendon tissue outcomes, especially in older women. This research study will assess the effects of consuming a healthy, protein-rich diet emphasizing lean beef, compared to a healthy, normal-protein, lower beef diet (control 1), and a healthy protein-rich, lower beef diet emphasizing non-beef/red meat protein (control 2) on resistance training-induced changes in muscle and tendon tissue size, strength, and quality in older women.

Assessing Timing of Enteral Feeding Support in Esophageal Cancer Patients on Muscle functTion and Survival

The surgical stress of an esophagectomy causes a detrimental impact on the physiological response of the body. In this perspective, one could question whether the current feeding regimens of starting early nutritional support at postoperative day (POD) 1 have a similar negative impact on the muscle mass as documented in critically ill patients. This study will introduce relative starvation in the early days following esophagectomy compared to the current regimen of early enteral nutritional support. The research team aims to investigate whether the negative impact on muscle mass and muscle function might be reduced, which should result in enhanced postoperative recovery. The final result of the study will be a well-documented and scientifically substantiated nutritional regimen for patients who underwent an esophagectomy for cancer.

Appendicular Skeletal Muscle Mass Study

There is a lot of discussion concerning the normal cut-off points of skeletal mass among different populations worldwide. Genetic and environmental differences most probably lead to different measurements. Defining muscle mass in healthy young adults in Greece will provide information that can be used to determine normal ranges of muscle mass of both sexes and consequently define sarcopenia. The aim of the study is to define appendicular skeletal muscle mass reference measurements in healthy young adults in Greece. These values can be used to determine sarcopenia cut-offs according to recommendations.

Electrical Stimulation of Human Myocytes in Microgravity

The purpose of this study is to evaluate the changes of muscle, in microgravity. Which will help explain the health benefits of exercise. There are tests that can be done to tell researchers more about the human body, such as a dual energy x-ray absorptiometry (DEXA) scan, which measures body composition (fat and lean body mass). The use of muscle testing and a Handgrip test can tell us about the strength and power within an individual's muscles. A VO2 max test helps us understand the aerobic fitness level of an individual and one of the most important aspects of this study are muscle cells. A muscle biopsy allows us to obtain muscle cells from the thigh, which will be sent into space by a rocket. Researchers will study these muscle cells in a low gravity environment aboard the International Space Station. Studying the muscle cells under those conditions will potentially mimic an accelerated aging process, which will help researchers better understand muscle wasting in the elderly.

Multidimensional Intervention in Pre-frail Patients Older Than 70 Years

Aging represents a huge advance in society and a health and social challenge. Spain has one of the highest life expectancies in the world, but other countries with the same demographic characteristics are ahead of us in quality adjusted life years. Primary care setting has the main drivers of healthy aging, acting on the early stages of pre-frailty and frailty. Therefore, it is proposed a multicomponent intervention (nutritional and prescription of physical exercise) in patients older than 70 years of the Medina del Campo Health Center, with pre-frailty criteria, in order to measure the changes that this intervention produces in their mild dysfunction and whether it is capable of reversing it or delaying the progression to a state of frailty.

Sarcopenia Prevention With a Targeted Exercise and Protein Supplementation Program

Physical inactivity and protein malnutrition have been implicated to be key and modifiable causes of enhanced muscle mass loss among seniors. However, the individual benefit, as well as the additive or possibly interactive benefit of exercise and Protein supplementation on fall prevention has yet to be confirmed in a large clinical trial. This study aims to test the individual and combined effect and cost-effectiveness of a simple home exercise program and / or protein supplementation on the risk of falling in seniors at high risk of progressive muscle mass loss and sarcopenia.

Body Composition Manipulation in CoLorectal cancEr (BiCyCLE): Neuromuscular Electrical Stimulation (NMES)

Muscle is lost as part of the rectal cancer disease process. Surgery to treat rectal cancer and its subsequent immobility leads to increased muscle loss. Neuromuscular electrical stimulation (NMES) has been shown in previous studies in the critically ill to maintain muscle mass. The investigators aim to examine whether NMES use in the pre and postoperative setting preserves muscle mass, speeds up recovery and improves outcomes in advanced rectal cancer patients undergoing curative surgery. This is a phase II double blind randomised controlled clinical trial.

Electrostimulation of Skeletal Muscles in Patients Listed for a Heart Transplant

Heart transplantation is the best way to treat terminal heart failure, which can improve the quality and life expectancy of patients, as well as contribute to their social and labor rehabilitation. Actually, the procedure of heart transplantation is a complex procedure that requires the coordinated work of cardiologists, cardiac surgeons, anesthetists, perfusionist, nurses, as well as the administration of medical organizations. It is known that the restriction of motor activity in patients with heart failure leads to a loss of muscle mass, as well as a decrease in its strength and endurance. In patients with heart failure, the low functional status of skeletal muscle is associated with poor prognosis, regardless of gender, age, and concomitant coronary heart disease. Optimization of drug therapy and appropriate use of resynchronization therapy can improve functional status, as can patient engagement in exercise. Although exercise is recommended as a component of heart failure management, adherence is consistently low. This is particularly troubling because exercise has great potential as a low-risk, low-cost intervention to improve functional status and quality of life while decreasing heart failure symptoms and hospitalizations in patients with heart failure. Low adherence is due in part to inadequate strength and inability to tolerate or sustain even low levels of activity. In this study, we propose to use neuromuscular electrical stimulation to assist patient initiation of quadriceps strengthening in order to progressively increase low exercise tolerance.

Prehabilitation for Cardiac Surgery in Patients With Reduced Exercise Tolerance

Among patients awaiting cardiac surgery, a significant proportion are patients with severe angina, heart failure (HF) and peripheral atherosclerosis. These factors are predictors of an unfavorable near and long-term prognosis after open cardiac surgery. It is known that the restriction of motor activity in patients with peripheral atherosclerosis and HF leads to loss of muscle mass, as well as to a decrease in its strength and endurance: secondary (disuse) sarcopenia is formed. In patients with peripheral atherosclerosis and HF, the low functional status of skeletal muscles is associated with a poor prognosis, regardless of gender, age, and concomitant coronary artery disease. A number of studies have shown that the deterioration of muscle status before abdominal, orthopedic and vascular surgery interferes with the close results of surgery, increases the number of complications, the length of ICU and in-hospital stay. Thus, sarcopenia serves as an additional factor worsening the prognosis. Therefore, efforts aimed at improving the functional status in patients planning an open cardiosurgical surgery seem to be very justified. Standard preoperative management of patients includes the identification and correction of comorbidities and the optimal medical treatment. The idea of "rehabilitation" means an additional improvement in the functional capabilities of patients awaiting surgery. Prevention includes outpatient outreach and educational work by nurses, as well as preoperative physical exercises. For this, multi-level training is used: respiratory exercises for the patients with the most severe illness, free movements of the limbs without load, or bike or treadmill training with increasing load for tolerable patients. However, adequate physical rehabilitation is difficult particularly on an outpatient basis. Low adherence is due in part to inadequate strength and inability to tolerate or sustain even low levels of activity due to angina, chronic lower limb ischemia and heart failure symptoms. In this study, the investigators propose to use neuromuscular electrical stimulation (NMES) to assist patient initiation of quadriceps strengthening in order to progressively increase low exercise tolerance.

Protein Supplementation Intervention for Improving Muscle Mass and Physical Performance in Older People With Sarcopenia

Background: Declines in muscle mass and strength are expected with aging, but physical inactivity and low protein intake have been suggested as risk factors of sarcopenia. So far, lifestyle interventions, especially exercise and nutritional supplementation, prevail as mainstays of treatment for sarcopenia. Objective: To explore the effect and benefits of protein supplementation on the improvement of muscle mass and physical performance in older people with sarcopenia. Design: A randomized, double-blind, placebo-controlled clinical trial. Methods: Participants aged 65-95y who meet the following criteria will be invited: (1) muscle mass: bioimpedance, <7.0 kg/m² (male) and <5.7 kg/m² (female), (2) handgrip strength: <28 kg (male) and <18 kg (female), and (3) low physical performance: 6-m gait Speed <1.0 m/s. Study participants will be randomly assigned to two groups. The experimental group will receive a 12-week intervention with?protein (14g)+ BCAA(4.4g)? drink per day, while the parallel control group will receive a placebo oat drink per day. Participants in the control group will be asked to maintain participants' usual diet and physical activity. There are 3 time-points to measure outcomes and observe other required information, at week 0(baseline), 6 and 12.

Impact of Whey Protein Supplementation on Body Weight and Metabolic Parameters of Bariatric Patients

Obesity is a metabolic disorder, characterized by an increase in the body's fat mass, which will reflect an increase in total body weight. In Brazil, overweight accounts for 53.8% of the population, and of these 18.9% are obese. Surgical treatment is currently the most successful method for weight loss in patients with Grade III obesity and reduced associated morbidities. The general objective is to evaluate genetic, inflammatory, and dietary factors that would influence weight loss and the appearance of protein deficiency or sarcopenia in patients undergoing bariatric surgery and to evaluate the effects of protein supplementation for 8 weeks after the 18th postoperative month in the parameters evaluated. The study has a randomized, placebo-controlled, double-masked model. The patients will be selected in two bariatric surgery services accredited by the Brazilian Health Unic System (SUS) in the city of Belo Horizonte, Brazil. The project has already been approved by the Brazilian Ethics committee CONEP/UFMG by nº. 75415317.8.0000.5149. Patients of both sexes over 20 years of age will be included, attending the hospitals of the project with regular follow-up in the postoperative period. Data on anthropometry, body composition, muscle strength, energy expenditure, and inflammatory profile will be collected. The data will be correlated with the evaluation of the presence of genetic polymorphisms.
