The purpose of the DETECT study is to learn more about how some breast tissue features show up on a mammogram and what these features can tell us about the potential for a breast cancer diagnosis. Your participation will help us understand how the appearance of those breast tissue features is affected by hormone levels. Our objective is to collect urine samples that we will use to measure hormone levels. We will examine how hormone levels are related to breast tissue features measured from a breast cancer screening mammogram.

The purpose of this research study is to see how use of genetic testing to help doctors with choosing blood thinning medication after a heart procedure called an angioplasty (also called percutaneous coronary intervention or PCI) affects your risk of having a heart attack, stroke, death or bleeding. Some doctors use genetic testing to help decide which blood thinner to prescribe for a patient. By doing the study, the investigators will be able to look at clinical outcomes (heart attacks, stroke, death, bleeding) after genetic testing and prescribing of blood thinning medications for patients with different backgrounds and medical histories. They will also look for new genes that affect how blood thinners work.

The purpose of this study is to determine if peak flow meter data correlate well with other measures of subglottic disease severity and to see if peak flow meters can be utilized to monitor subglottic stenosis disease progression at home.

The virus that causes COVID-19 disease infects many people, but only some get sick. We want to understand how COVID affects the immune system and what makes severe COVID infections different from other diseases that cause hospitalization and breathing problems. We collect samples of blood, sputum, urine, and stool from patients in the hospital to learn how COVID affects cells and molecules of the immune system.

This study will test how effectively changes in lung structure and function can be detected with a new inhaled gas combined with a MRI.

The purpose of Heroes Health is to support COVID-19 worker health.

The goal of this study is to learn more about relationships, sexuality, family, work, and finances. This new information will help us understand factors that contribute to health among diverse adult populations including people who identify as straight or LGBT, as well as different races and ethnicities.

The purpose of this research study is to understand if convalescent plasma is a potential therapy and to understand the immune response to COVID-19 infection. Understanding the immune system's response after infection will help to inform vaccine design and the potential role of antibodies as therapeutics in the setting of COVID-19 infection and disease.

This is a research study to compare quality of life (QOL) and physical function impairment among breast cancer and lymphoma survivors in Malawi to age- and sex-matched controls, using the PROMIS survey and objective performance-based measures.

The purpose of this study is to determine the effect of sampling location on drug transporter levels in the healthy and diabetic placenta.
