This phase III trial compares less intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in treating patients with high risk prostate cancer and low gene risk score. This trial also compares more intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in patients with high risk prostate cancer and high gene risk score. Apalutamide may help fight prostate cancer by blocking the use of androgen by the tumor cells. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving a shorter hormone therapy treatment may work the same at controlling prostate cancer compared to the usual 24 month hormone therapy treatment in patients with low gene risk score. Adding apalutamide to the usual treatment may increase the length of time without prostate cancer spreading as compared to the usual treatment in patients with high gene risk score.

REACT-AF is a multicenter prospective, randomized, open-label, blinded endpoint (PROBE design), controlled trial comparing the current Standard Of Care (SOC) of continuous Direct Oral Anticoagulation (DOAC) use versus time-delimited (1 month) DOAC guided by an AF-sensing Smart Watch (AFSW) in participants with a history of paroxysmal or persistent Atrial Fibrillation (AF) and low-to-moderate stroke risk.

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) Study has been to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI4 continues the previously funded ADNI1, ADNI-GO, ADNI2, and ADNI3 studies that have combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of AD.

This is a longitudinal study with regular quantitative assessments of all participants every six months for 3 years. The quantitative portion of the study will recruit couples, consisting of individuals over the age of 65 who are in a committed relationship. Both members of the couple must be willing to participate at baseline. The assessment is in two parts. In the first part, each member of the couple will be asked the following: demographic information, mental health history, self-reported physical and emotional health, measures of emotional and mental health, personality, relationship and attachment style, social support and self-efficacy. Then each member of the study couple will be asked a series of questions to determine whether they consider themselves a caregiver. If they do, individuals will be asked to respond to additional caregiver questionnaires. Follow-ups will occur every six months for the study couples for a total of three years from the baseline visit. Each visit, the entire assessment except for demographic questions, will be re-administered to each individual in the couple. At the end of each questionnaire battery, individuals will be screened for cognitive impairment and those who are in the middle to advanced stages of dementia will no longer participate. Recruitment will end when 600 individuals (300 couples,150 couples at each site) are enrolled in the longitudinal portion of the study. All study visits will be conducted virtually via Zoom or WebEx video conferencing. Analyses will be conducted to determine the association between changes in dyadic relationship and changes in mental health and cognitive outcomes, to elucidate how relationship characteristics impact health and well-being as perceived by each member of the dyad.

Purpose: About 6.4% of the U.S. population suffers from posttraumatic stress disorder (PTSD). Trauma-focused psychotherapies are generally effective in PTSD, but responses vary greatly across individuals and PTSD subpopulations. Neurobiological factors impacted by life experiences, stress, and genetics can affect treatment responses. These factors can alter brain capacities needed to reprocess traumatic memories prevent them from triggering intensely distressing, disruptive, out-of-place responses. For example, during psychotherapy for PTSD, trauma memory activation engages two competing brain processes that affect recovery: "extinction" versus "reconsolidation" of trauma-related emotional, physiological, and behavioral responses. This study tests whether a single intravenous (IV) dose of allopregnanolone (Allo) compared to placebo (which is non-active): 1. promotes consolidation of extinction learning (sub-study 1) or 2. blocks reconsolidation physiological responses triggered by aversive memories (sub-study 2). The study also tests whether Allo compared to placebo affects retention of non-aversive memories.
