An international research registry called the CorEvitas International Adolescent Alopecia Areata (AA) Registry (the "CorEvitas Registry"). This observational registry studies adolescent patients with AA between 12-17 years of age under the care of a dermatology provider diagnosed with moderate to severe alopecia areata.

The TEAM-HF trial aims to find out whether measuring pressure in the heart and lungs using an implantable device called a CardioMEMS can help identify heart failure patients who are getting worse and may benefit from earlier treatment with a heart pump called an LVAD. It also seeks to determine if patients with advanced heart failure, who are not on IV medications for their heart failure but still have high pressures in their heart and lungs can improve with LVAD therapy.

This is an international, multicenter, study that will not prescribe elafibranor. It is designed primarily to collect data and assess real-world effectiveness of treatment with elafibranor 80mg/day on adult patients with PBC, and to describe the safety of this treatment and its impact on their quality of life, over a period of 24 months.

The purpose of this study is to learn more about late-onset epilepsy of unknown etiology (LOEU), which is defined as an onset of seizure activity in late life (age 55 or above) without a clear neurological cause. That is, many older adults will experience seizures due to neurological conditions such as stroke, brain injury, tumor, or infection. However, other individuals will also develop seizures with no identified cause.

Participation entails a single study visit approximately 3 hours including a blood draw, completion of standardized cognitive testing, and several questionnaires. The goals of the study include to examine blood markers that can help us to better understand the condition including dementia risk, and how these markers may impact the clinical presentation of the condition. No interventions/treatments are included with this study.

Eligible participants (ages 18+ whom have daily cigarette use) will attend an in-person assessment (though some aspects of the study, including consent, can be completed remotely). Participants will submit a breath sample for assessment of expired carbon monoxide. Approximately 5-7 days after completion of the in-person assessment, participants will meet with research staff. A medical clinician will meet with the participant to present a smoking cessation treatment recommendation along with resources. Participants will also complete surveys to assess their treatment preferences, motivation, and self-efficacy following receipt of the recommendation.

This is a research study to help see if a new interview for posttraumatic stress disorder (PTSD), called the Revised Clinician-Administered PTSD Scale for DSM-5, or the CAPS-5-R for short, is accurate and reliable for veterans. By doing this study, we hope to learn if the CAPS-5-R can be used in VA to diagnose PTSD. Participation will all be done remotely. Joining this study will involve (1) completing some questionnaire measures and (2) completing an interview remotely by videoconference over 2 days at most.

Participants must be Veterans, aged 18 or older in the Ralph H. Johnson VA Health Care System who have experienced trauma or at least one PTSD symptom.

This study will compare the safety, tolerability, and efficacy of inhaled study drug LTI-03 to placebo in participants diagnosed with IPF within 5 years of Screening who may be receiving standard of care (SoC) antifibrotic therapy. Taking part in this research is expected to last up to 32 weeks, which includes a 4-week screening period, a 24-week treatment period, and 4-week post-treatment follow-up period. The general procedures include review of eligibility; review of medical and medication history and changes in health; completing questionnaires; undergoing physical exams and having vital signs measured; collecting blood samples; examinations such as ECG, spirometry, HRCT, and DLCO and using an inhaler to take the study drug.

The study is researching an experimental drug called REGN7544. The study is focused on adult patients (18 to 85 years old) hospitalized due to a serious infection (called "sepsis" in this form) and receiving standard-of-care medications for low blood pressure (called "vasopressors" in this form) due to sepsis. The aim of the study is to see if REGN7544 is safe, tolerable and effective when compared to placebo, by observing the effects on blood pressure and the total amount of vasopressor dose received. The general procedures include collection of information from medical records, some additional testing, such as electrocardiogram, collection of blood, and having blood pressure and heart rate measured .There will also be a screening visit, two telephone visits, and one additional in-person visit. It is expected that taking part in this research will last about 13 weeks (3 months).
