Early Exercise-Based Rehabilitation in Patients Hospitalized for Acute Pulmonary Embolism

Up to half of patients with pulmonary embolism (PE) suffer from impaired quality of life, reduced physical capacity, and symptoms like shortness of breath even three months after diagnosis, despite standard treatment with anticoagulation (blood thinners). The randomized RehabPE trial investigates whether an early, structured rehabilitation program with physical training and patient education can prevent such long-term effects. The study includes hospitalized patients with acute symptomatic PE who are at increased risk of impaired quality of life three months after diagnosis. After informed consent, patients are randomly assigned to one of two groups: one receives an early 6-8-week, center-based rehabilitation program; the other receives standard follow-up care without rehabilitation. The intervention group completes 16-18 outpatient sessions of endurance and strength training, along with two education sessions covering the condition, treatment, and symptom management. Over 180 days, changes in quality of life, physical exercise capacity, breathlessness, and psychological symptoms, and the time to return to work / usual daily activities will be monitored and compared between groups.

Nicotinamide Mononucleotide Supplementation for Exercise Tolerance Improvement in Healthy Older Adults

This is a randomized, double-blind, placebo-controlled, two-arm crossover clinical trial evaluating the effects of a patented age-reversal therapy, EGA®, compared to conventional nicotinamide mononucleotide (NMN) supplementation. The study will assess safety and efficacy in improving exercise tolerance and modulating biomarkers of aging in healthy older adults. The primary outcome is cycle ergometry constant work rate (CWR) exercise tolerance, measured as time to fatigue. Secondary outcomes include changes in peak oxygen consumption (VO₂peak), critical power, anaerobic work capacity, lactate threshold, and NAD⁺ metabolite levels. EGA® is composed of three metabolomic compounds that are endogenous to humans. The formulation has been used in prior exploratory studies and real-world applications, which have helped inform the design of this current trial.

M4C Nutraceutical Intervention Human Health Effects Pilot

This 3 month pilot study will be an unblinded, convenience sampling, nutraceutical intervention trial. Twenty fasted subjects will undergo a baseline health assessment via a questionnaire, baseline clinical chemistries, blood lipids, dexa and impedence testing (to identify bone mineral density and body muscle/fat/water composition), and metabolite/novel biomarker testing through whole capillary blood, saliva, and urine collections. Assessments will be repeated every month (3 times after initial assessment) to cover a 3 month period. All measurements from each visit will be compared with baseline using paired t-tests or Chi square testing depending on variable. Power analyses are not included due to the pilot nature of the study. This pilot study will provide the necessary variability estimates for future trials.
