Researchers are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse. Sotatercept is a study medicine designed to treat PAH. It is a targeted therapy, which is a treatment that works on certain proteins that play a role in causing PAH. This is a long-term follow-up (LTFU) study. People who took part in certain other studies testing sotatercept for PAH may be able to join this study. The goal of this study is to learn about the long-term safety of sotatercept and if people tolerate it when taken with standard PAH treatment over a longer period of time.

The goal of this clinical trial is to learn if therapy with activin ligand-trap biological therapy (an investigational drug) combined with exercise training can improve exercise capacity and cognitive function in heart failure with preserved ejection fraction (HFpEF). The main questions it aims to answer are: - Does activin-ligand trap biological therapy improve exercise capacity as measured by change in peak oxygen uptake (peak VO2) from baseline to week 12? - Does activin-ligand trap biological therapy improve cognitive function as assessed by the NIH-Toolbox Cognition Battery (NIHTB-CB) composite score and Rey Auditory Verbal Learning Test (RAVLT) from baseline to week 12? Researchers will compare activin-ligand trap biological therapy to a placebo (a look-alike substance that contains no drug) to see if activin-ligand trap therapy works to improve exercise capacity and cognitive function in patients with HFpEF.

This phase Ib trial tests the safety, side effects, and how well cytomegalovirus (CMV)-modified vaccinia Ankara (MVA) Triplex vaccine works in enhancing CMV-specific immunity and preventing CMV viremia in patients undergoing haploidentical hematopoietic stem cell transplant. Haploidentical stem cell transplantation (haploHCT) has advanced to become the predominant procedure for patients lacking a matched donor. Compared to matched related donor transplants, the rate of significant CMV infection is higher in patients undergoing a haploHCT. Significant CMV infection is associated with an increased risk of complications and death. Vaccination is the main preventative approach to limit complications and death in immunocompromised patients at high risk of post-stem cell transplant infections. CMV-MVA Triplex vaccine, is a CMV vaccine based on the attenuated poxvirus, modified vaccinia Ankara (MVA), developed to enhance CMV-specific immunity in both healthy stem cell transplant donors and stem cell transplant patients to prevent significant CMV infection post-stem cell transplant. Giving CMV-MVA triplex vaccine may be safe, tolerable and/or effective in enhancing cytomegalovirus (CMV)-specific immunity and preventing CMV viremia in patients undergoing a haploHCT.

The observational study titled "Observational Assessment of Support with Impella Best Practices in Acute Myocardial Infarction Complicated by Cardiogenic Shock (OASIS-AMICS)" aims to evaluate the safety outcomes of patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) who receive Impella CP during percutaneous coronary intervention (PCI) and who are managed with Impella best practices while receiving guideline-directed standard of care. This prospective, multicenter study will enroll up to 350 hemodynamically unstable patients with cardiogenic shock of less than 12 hours duration and acute myocardial infarction (AMI) of less than 24 hours duration. Cardiogenic shock will be confirmed by tissue hypoperfusion (lactate ≥ 2.5mmol/L and/or SvO2 <55% with a normal PaO2) and systolic blood pressure <100 mmHg and/or need for vasopressor therapy (dopamine/norepinepherine or epinephrine). Patients will be assessed for various safety endpoints, including a composite safety endpoint involving major bleeding, acute limb ischemia, and acute kidney injury. Secondary endpoints will evaluate all-cause mortality, major adverse cardiovascular and cerebrovascular events (MACCE), and hospitalizations through 1-year post-Impella implant. All patients presenting with AMICS at study sites will be screened for inclusion in the study after hospital discharge (or after death, if prior to hospital discharge). IRB approved consent waiver will be used to collect data from electronic health records from; Impella placement to discharge and post-discharge at 30 days post-Impella implant, 6 months post-Impella implant, and 1 year post-Impella implant.

The purpose of this study is to find out whether a medicine called spesolimab helps people with pyoderma gangrenosum (PG). The main aim is to see whether spesolimab leads to closure of PG ulcers. This study is open to adults with ulcerative PG with at least 1 ulcer that measures between 5 cm^2 to 80 cm^2 in size. This study has 2 parts. In Part 1, participants are put into groups randomly, which means by chance. 1 group gets spesolimab and the other group gets placebo. Placebo infusions look like spesolimab infusions, but do not contain any medicine. Every participant has a 2 in 3 chance of getting spesolimab. For the first 8 weeks, participants also take corticosteroid medicine by mouth. In Part 2, participants are put into groups again. Participants without open ulcers have an equal chance of getting spesolimab or placebo. Participants with open skin ulcers will get spesolimab. In both parts, participants receive spesolimab or placebo as an infusion into a vein every 4 weeks. Participants are in the study for about 1.5 years. During this time, they visit the study site 20 times. At study visits, doctors check the participant's skin for signs of PG. The doctors also regularly check participants' health and take note of any unwanted effects. The results of the groups are compared to see whether the treatment works.

Spinocerebellar ataxias (SCA) are genetic neurological diseases that cause imbalance, poor coordination, and speech difficulties. There are different kinds of SCAs and this study will focus on types 1, 2, 3, 6, 7, 8, 10, 27B, and RFC1-ataxia (SCA 1, SCA 2, SCA 3, also known as Machado-Joseph disease, SCA 6, SCA 7, SCA 8, SCA 10, SCA27B, and RFC1-ataxia, also known as CANVAS). The diseases are rare, slowly progressive, cause increasingly severe neurological difficulties, and are variable across and within genotypes. The purpose of this research study is to bring together a group of experts in the field of SCA for the purpose of learning more about the disease. The research questions are: 1. How do these diseases progress over time? 2. What are the best ways to measure the progression? 3. Do some genes, other than the gene that is abnormal in these diseases, have any effect on the way the disease behaves? This is a nationwide study and the investigators expect that 1400 patients will participate all over North America. The participants will remain in the study for an indeterminate period of time, for as long as they are willing to participate. Study visits will be done every 12 months. Within the broader CRC-SCA, there is an Imaging Sub-study aiming to identify magnetic resonance imaging (MRI) markers sensitive to the onset and progression of common SCAs. To accomplish this, participants attend annual visits involving a neurological exam, surveys, a blood draw, and an MRI scan. Participants can attend visits at one of three US locations - Minneapolis, MN; Gainesville, FL; or Dallas, TX and two European locations - Paris, France and Bonn, Germany. Eligible participants must either have SCA1, 2, or 3 or have been a participant of the previous READISCA study (NCT03487367). Gene-positive participants must have a SARA score less than 10; however, there is no SARA limit for participants previously enrolled in READISCA. All participants must be 18 years or older. Gene-negative participants should be 25-65 years old.

The investigators will conduct a 3-arm, pilot RCT where participants (N=30) will be randomized in a 1:1:1 design to 4 weeks of instructed bedtime MM practice at night (n=10) vs. uninstructed MM (n=10) vs. sleep hygiene education only (n=10). Aim 1 is to understand the feasibility and acceptability of the intervention and study procedures. Aim 2 is to explore patterns of within-group changes in sleep outcomes (i.e., insomnia severity and sleep quality). Patient-reported outcomes will be collected using a HIPAA-compliant electronic data management system (REDCap). Following informed consent, participants will receive links to REDCap surveys via email at Weeks 0, 4, 8, and 16. The investigators will also conduct a post-intervention interview at the end of Week 4 and an exit interview at Week 16. All participants will also receive a research kit with wearable devices and meet with our staff after they receive the kit for instructions. Data collected in the pilot RCT will help us to preliminarily identify tools for subjective measures and physiological signals to inform a future trial.
