The purpose of this study is to understand how pain and weakness due to knee osteoarthritis affect inflammation and quadriceps muscle function during walking.

Para nuestro proyecto, estamos estudiando una evaluación del desarrollo infantil que pueda hacerse a distancia desde la casa de la familia. Esta se llama "Evaluación del neurodesarrollo con ayuda de los padres" o "PANDABox", según su acrónimo. PANDABox se ha usado con familias que hablan inglés, pero no se había traducido al español hasta ahora. De modo que hay dos razones por las que estamos haciendo nuestro estudio: primero, traducir la evaluación al español; y segundo, probar la evaluación con familias latinas con bebés que podrían beneficiarse de una evaluación del desarrollo. Después de probar la evaluación, les preguntaremos a las familias cómo fueron sus experiencias y si tienen alguna sugerencia para mejorarla. En general, esperamos mejorar la evaluación PANDABox en cuanto al idioma y la cultura de las familias que hablan español.

In this study, we want to learn if wearable technology can be used to assess interactions between grandparents and grandchildren. We want to find out if these interactions affect markers associated with grandparent wellbeing. This study will help us to develop new methods that will let us better understand the impact of grandparenting on the health of grandparents.

The purpose of this research study is to better understand the cause and course of clinical high-risk symptoms and to monitor participants for the possible development of mental illnesses such as psychosis. Clinical high-risk symptoms can include feeling low in mood, feeling like something odd is going on, feeling suspicious, or seeing or hearing things that the person knows aren't there. Some people might worry that their thoughts are being heard or might be having more difficulty than usual coping with work, school, or relationships. For some, these early symptoms may become more severe over time. For others, the symptoms may stay the same, decrease, or go away entirely. Improving our knowledge about these symptoms and risk factors and the way that they change over time may help researchers and clinicians predict possible outcomes for individual patients and develop treatment plans that are best suited to individual patients.

Do you ever wonder if there is a connection between oral and gut health and food allergies? Well, so do we! We are trying to enroll pediatric participants in our registry study to determine what the link is and use it to possibly help treat patients in the future.

The purpose of this study is to explore what a church is and what it means to attend one. In this study, we will interview people who have personal experience designing, leading, or leaving church spaces.

In this study, we want to follow people after getting a COVID-19 vaccine to test the level of immune proteins in their noses. This non-invasive test will help us learn more about immunity to COVID-19. We will compare the antibody levels in the nose to those in the blood.

In this study, we will interview Black and African American EMS providers. We want to learn about their experiences in this line of work, with a focus on the COVID-19 pandemic and nationwide protest relating to police killings of Black citizens. Our goal is to characterize this experience and explore reasons for low recruitment and retention of Black EMS providers.

Help us learn more about COPD! We want to better understand how your body responds to the nasal flu vaccine and its relation to COPD. We are looking for people with COPD and healthy volunteers for this study. Compensation provided.

We are developing a computer-based tool for people who have cancers of the blood, bone marrow, and lymph nodes. This tool will help us understand what is most important to patients when it comes to the results of their treatment. We are looking for healthy volunteers (those without cancer) to help us test the usability of this tool.
