Internal Medicine Heart and Vascular Heart Disease Adult Subjects Female Subjects Male Subjects

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.

IORA: A022101 A Pragmatic Randomized Phase III Trial Evaluating Total Ablative Therapy for Patients with Limited Metastatic Colorectal Cancer: Evaluating Radiation, Ablation, and Surgery (ERASur)

Cancer Internal Medicine Heart and Vascular Colorectal Cancer Electrophysiology Adult Subjects

This phase III trial compares total ablative therapy and usual systemic therapy to usual systemic therapy alone in treating patients with colorectal cancer that has spread to up to 4 body sites (limited metastatic). The usual approach for patients who are not participating in a study is treatment with intravenous (IV) (through a vein) and/or oral medications (systemic therapy) to help stop the cancer sites from getting larger and the spread of the cancer to additional body sites. Ablative means that the intention of the local treatment is to eliminate the cancer at that metastatic site. The ablative local therapy will consist of very focused, intensive radiotherapy called stereotactic ablative radiotherapy (SABR) with or without surgical resection and/or microwave ablation, which is a procedure where a needle is temporarily inserted in the tumor and heat is used to destroy the cancer cells. SABR, surgical resection, and microwave ablation have been tested for safety, but it is not scientifically proven that the addition of these treatments are beneficial for your stage of cancer. The addition of ablative local therapy to all known metastatic sites to the usual approach of systemic therapy could shrink or remove the tumor(s) or prevent the tumor(s) from returning.

ACNS2321: A Phase II Trial Evaluating Chemotherapy followed by Response-Based Reduced Radiation Therapy for Patients with Central Nervous System Germinomas

Cancer Pediatrics Neurology Heart and Vascular Stroke Vascular Disease Pediatric Subjects Adult Subjects

This phase II trial studies how well lower dose radiotherapy after chemotherapy (Carboplatin \& Etoposide) works in treating children with central nervous system (CNS) germinomas. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Researchers want to see if lowering the dose of standard radiotherapy (RT) after chemotherapy can help get rid of CNS germinomas with fewer long-term side effects.

Role of the Mineralocorticoid Receptor in Microvascular Endothelial Dysfunction after Preeclampsia

Heart and Vascular Heart Disease Vascular Disease Healthy Subjects Adult Subjects Female Subjects

Women who develop preeclampsia during pregnancy are more likely to develop and die of cardiovascular disease later in life, even if they are otherwise healthy. Importantly, women who had preeclampsia have an exaggerated vascular responsiveness to hypertensive stimuli, such as high-salt intake, compared to women who had a healthy pregnancy. The reason why this occurs is unclear but may be related to impaired endothelial function and dysregulation of the angiotensin system that occurs during the preeclamptic pregnancy and persists postpartum, despite the remission of clinical symptoms. While the association between a history of preeclampsia and vascular dysfunction leading to elevated CVD risk is well known, the mechanisms underlying this dysfunction remains unclear.

The purpose of this study is to examine the role of vascular mineralocorticoid receptor, the terminal receptor in the angiotensin system that contributes to blood pressure regulation, in mediating exaggerated microvascular endothelial dysfunction before and after a high-salt stimulus. This will help us better understand the mechanisms of microvascular dysfunction these women, and how inhibition of these receptors may improve microvascular function.

In this study, we use the blood vessels in the skin as a representative vascular bed for examining mechanisms of microvascular dysfunction in humans. Using a minimally invasive technique (intradermal microdialysis for the local delivery of pharmaceutical agents) we examine the blood vessels in a nickel-sized area of the skin.

Metformin and Vascular Function in Prediabetes

Internal Medicine Endocrinology Heart and Vascular Diabetes Vascular Disease Heart Disease Adult Subjects Female Subjects Male Subjects

The goal of this clinical trial is to investigate whether metformin improves vascular function in individuals with prediabetes. The main questions it aims to answer are:

1. Does metformin improve large conduit artery endothelial function in individuals with prediabetes?
2. Does metformin improve microvascular endothelial function in individuals with prediabetes?

Researchers will compare metformin to a placebo to see if metformin improves vascular function in prediabetes.

The trial duration is 12 weeks. Participants will take metformin or a placebo once a day for 2 weeks. After 2 weeks, participants will take metformin or a placebo twice a day for the remaining 10 weeks. There will be a screening visit, two baseline visits, a 4-week safety visit, and two 12-week end-of-study visits. Adherence will be calculated from pill count and adverse events will be quantified via a questionnaire.

Role of inflammation in vascular phenotype associated with e-cigarette use

Heart and Vascular Heart Disease Vascular Disease Healthy Subjects Adult Subjects Female Subjects Male Subjects

The use of electronic nicotine delivery systems, or e-cigarettes - colloquially referred to as "vaping" - in the United States has increased exponentially since their introduction to the US market in 2007. Prevalence of ever and current e-cigarette use is highest among teenagers and young adults with 16-28% of this population having reported vaping. While the majority of e-cigarette users are current tobacco smokers, 32.5% of current e-cigarette users are never- or former-smokers, representing a growing population of young adults who exclusively vape. While e-cigarettes have been marketed as a safer alternative to tobacco cigarettes, clinical studies examining these claims are limited. Cardiovascular disease (CVD) is the primary cause of premature death among tobacco cigarette smokers and reductions in vascular endothelial function, a significant predictor of future CVD, are detectible in otherwise healthy young adults who smoke. Despite the explosion in e-cigarette use among young adults, the health effects - especially the effects on mechanisms of vascular function - of these devices remain relatively unexplored. The purpose of this study is to directly asses the mechanistic role of inflammation in this dysfunction.
