The Modulatory Effect of Female Sex Hormones on Spinal Neuroplasticity (TMSpine)
The goal of this project is to test our central hypothesis that the spinal cord neuroplasticity in females will be modulated by the level of estradiol concentration. under aim 1 we will determine the influence of estradiol fluctuations on spinal circuit excitability post afferent (sensory) mediated subthreshold motor priming in young healthy females and males. We will use an established repetitive peripheral nerve electrical stimulation with a stimulation intensity below the motor threshold to prime the spinal motor circuits. under aim 2 we seek to characterize the input output property of spinal circuit excitability after descending drive (motor) mediated priming in young healthy male participants. in aim 3 we will examine the influence of estradiol fluctuations on descending drive mediated motor priming in young healthy females.

Home-based Cardiac Rehabilitation in Heart Failure
This study evaluates a mobile health (mHealth) home-based cardiac rehabilitation program for patients with heart failure. We will stratify randomization between rural and urban populations, with the goal to assess implementation of cardiac rehabilitation across these two geographic areas. . The study will randomize 332 patients with heart failure (ejection fraction ≥35%) who are not eligible for center-based rehabilitation to either a 12-week mHealth cardiac rehabilitation program or an attention control group, with outcomes measured over 6 months using a composite endpoint of mortality, hospitalizations, and quality of life. We will then assess the implementation of the intervention.

Efficacy of LoDoCo in Improving Exercise Capacity Among Patients With HFpEF and Inflammation
The purpose of this research study is to determine the effectiveness of low dose colchicine (LoDoCo) on measures of exercise capacity, physical function, frailty, and quality of life, among patients with heart failure with chronic stable preserved ejection fraction (HFpEF) and systemic inflammation. The use of LoDoCo in this study is considered investigational as it has not been approved by the Food and Drug Administration (FDA) for the treatment of exercise capacity in patients with HFpEF. Participants will undergo a 1-day screening that includes a blood draw and physical examination. If deemed eligible for the study, participants will undergo a baseline visit within 2 weeks of screening visit that includes physical examination, exercise testing, echocardiography and completion of quality-of-life surveys. Participants will also be randomized at this visit (randomly assigned to a group) to receive either LoDoCo or placebo (inactive substance) for 3 months. Participants will be called back at 3 months for repeat physical examination, blood draws, echocardiography, exercise testing and completion of quality-of-life surveys. Each visit will take about 3 hours. Total study duration is about 3 months.

A Research Study to Look at How Ziltivekimab Works Compared to Placebo in People With Heart Failure and Inflammation (HERMES)
This study will be done to see if ziltivekimab can be used to treat people living with heart failure and inflammation. Participants will either get ziltivekimab or placebo. Participants will get study medicine for once-monthly injections either in a pre-filled syringe to inject the study medicine into a skinfold or a pen-injector to inject the study medicine into flat skin. The study is expected to last for up to 4 years. Participants will have up to 20 clinic visits. Participants will have to use a study app on their phone to record and share information about all their injections of study medicine and to fill in questionnaires.

Pharmacokinetics, Pharmacodynamics, and Safety Profile of Understudied Drugs Administered to Children Per Standard of Care (POPS) (POPS or POP02)
The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.
