Students Rising Above: Offsetting the Health and Mental Health Costs of Resilience
Recruiting
Students in marginalized communities who 'strive' to rise above adversity to achieve academic success are considered 'resilient'. However, youths' resilience in one domain (i.e. academic) can come at a cost in other domains including physical and mental health morbidities that are under-identified and under-treated. Previous research suggests that Black, Indigenous and People of Color (BIPOC) who exhibit a "striving persistent behavioral style" in the face of adversity evince later health morbid... Read More

A Study of Treatment of Inflammation Before Stem Cell Transplant in People With a Primary Immune Regulatory Disorder (PIRD) and/or an Autoinflammatory Condition
Recruiting
The researchers are doing this study to find out whether emapalumab or a combination of fludarabine and dexamethasone are effective in preparing people with a primary immune regulatory disorder (PIRD) and/or an autoinflammatory condition to receive a stem cell transplant. The researchers will look at how well the study treatments reduce inflammation and aid in the engraftment process (the process of donated stem cells traveling to the bone marrow, where they begin to make new immune cells.

A Study of Potential Disease Modifying Treatments in Individuals at Risk for or With a Type of Early Onset AD Caused by a Genetic Mutation
Recruiting
The purpose is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Stage 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Stage 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing d... Read More

A Study to Test How Different Doses of BI 1703880 in Combination With Ezabenlimab Are Tolerated in People With Different Types of Advanced Cancer (Solid Tumours)
Recruiting
This study is open to adults with different types of advanced cancer. People can take part if previous treatment was not successful, or no treatment exists. The purpose of this study is to find the highest dose of a medicine called BI 1703880 that people with advanced cancer can tolerate when taken together with ezabenlimab. BI 1703880 and ezabenlimab are medicines that may help the immune system fight cancer. In this study, BI 1703880 is given to people for the first time. Participants get B... Read More

PReclude Infection EVEnts With No Prophylaxis Transperineal Biopsy 2
Recruiting
Approximately one million transrectal prostate biopsies are performed annually in the U.S., and the risk of post- biopsy infection is increasing due to greater antibiotic resistance of rectal flora. Preliminary data demonstrates that a transperineal MRI-targeted biopsy approach under local anesthesia compared to the standard practice transrectal MRI-targeted prostate biopsy has a much lower risk of infection, comparable pain/discomfort and may improve detection of prostate cancer. This randomiz... Read More
