This study investigates the underlying mechanisms of a novel emotion regulation intervention among recently bereaved spouses. More specifically, this study examines how thinking about an emotional stimulus in a more adaptive way can affect the relationship between psychological stress, psychophysiological biomarkers of adaptive cardiac response, and brain activity. The emotion regulation strategy targeted is reappraisal, specifically reappraisal-by-distancing (i.e., thinking about a negative situation in a more objective, impartial way) versus reappraisal-by-reinterpretation (i.e., thinking about a better outcome for a negative situation than what initially seemed apparent). The study seeks to determine if relatively brief, focused reappraisal training in bereaved spouses will result in reduction of self-reported negative affect, increases in respiratory sinus arrhythmia (RSA; a measure of heart rate variability reflecting adaptive cardiac vagal tone), reduction in blood-based inflammatory biomarkers, and changes in neural activity over time. Reappraisal-by-distancing is expected to lead to greater changes in these variables relative to reappraisal-by-reinterpretation. Additionally, it is expected that across time decreases in self-reported negative affect, increases in RSA, reductions in blood-based inflammatory biomarker levels, and changes in neural activity will in turn lead to reductions in depressive symptoms and grief rumination. Finally, it is expected that distancing training will lead to reductions in depressive symptoms and grief rumination that are mediated by changes in the targeted neurobiological and behavioral mechanisms.

This is a randomized, double-masked study to evaluate the tolerability and safety of IRX-101 versus 5% povidone-iodine (PI) in subjects receiving intravitreal anti-VEGF injections. The study will be conducted in up to 15 centers in the United States (US). Read Less

Early identification in individuals with bipolar disorder who are at risk for AUDs could inform novel intervention strategies and improve life-long outcomes. The primary objective of this protocol is to use alcohol administration procedures and alcohol biosensor technology to investigate responses to alcohol, compared to placebo, and relationship with parental risk for alcohol use disorders and/or bipolar disorder in young adults. Baseline clinical, cognitive, and behavioral assessments will be completed in 100 young adults (21-26 years; 50% women, no history of AUDs>mild). Participants would be equally divided among those with parental history of bipolar disorder but not AUDs, parental history of bipolar disorder and AUDs, parental history of AUDs but not bipolar disorder, and typically developing age- and sex-matched controls with no parental history of mood disorders or AUDs (N=25 per group). Then, while wearing Secure Continuous Remote Alcohol Monitoring [SCRAM] sensors, participants will complete within-person, counter-balanced, beverage sessions (following standard beverage administration procedures) in a simulated bar laboratory. Changes in heart rate, body sway and subjective self-report measurements of intoxication will also be completed while under the influence of alcohol or placebo. Specifically, individual differences in transdermal alcohol concentration (the primary data output from SCRAM sensors), physiological changes (e.g. heart rate), and the experience of stimulating, sedative, and anxiolytic effects of alcohol (measured with self-report surveys) will be investigated and differences between parental risk subgroups and healthy comparison participants investigated. Differences in transdermal alcohol concentration collected while under the influence of alcohol will be the primary data outcome assessed. Changes in heart rate, body sway, and experience of stimulating, sedative, and anxiolytic effects (from self-report survey data) while under the influence of alcohol compared to placebo session will also be investigated. Additionally, associations between objective and subjective responses to alcohol and drinking patterns will be explored (secondary outcome). The primary endpoint of the study will be after completion of both alcohol and placebo beverage conditions. Read Less

The overall objective of this proposal is to develop and utilize a multicenter UM registry that will, in a longitudinal fashion, capture prospective data in order to characterize the natural history of UM and provide data that will be used to support the development of novel therapies for this disease. The care of patients with UM requires a multi-disciplinary team of physicians that commonly requires the involvement of both radiation oncology and interventional radiology, and is typically directed by an ophthalmologic oncologist at time of initial diagnosis of primary disease. Overall management is transitioned to a medical oncologist when distant recurrence is identified. In the case that a patient presents with metastasis at the time of diagnosis, a medical oncologist typically directs overall management. The management of surveillance for the development of metastasis following the treatment of primary disease is variable and, if performed at all, is managed by either an ophthalmologic oncologist or medical oncologist. Thus, the successful development of a registry that aims to capture the data regarding the full natural history of UM requires a collaborative effort including leaders from both the UM ophthalmologic oncology and medical oncology fields. To this end, the investigators have built an initial consortium of key ophthalmologic oncology and medical oncology leaders from multiple major UM centers in the United States. Read Less

This is a prospective, open-label trial to assess the efficacy of melanocortin receptor agonist bremelanotide (BMT) when administered with RAAS inhibition therapy after six months in subjects with Type II diabetic nephropathy. After six months of therapy, all subjects will remain in trial for further assessment and undergo a diagnostic renal biopsy to assess the effect of melanocortin therapy on diabetic histopathology at 12 months.

This project uses both transcriptomic- and genomic-level data to identify mechanisms of individual responses to glucagon-like peptide-1 (GLP-1) in Mexican-Americans with prediabetes. The GLP-1 hormone is essential for glucose reduction, weight loss, cardiovascular risk reduction, and renal protection. Newly discovered mechanisms will illuminate causal links between disease genotype and phenotype, which may ultimately guide personalized therapeutic approaches for type 2 diabetes, prediabetes, obesity, cardiovascular disease, renal disease, and other related diseases.

The CSP-2002 study will evaluate the safety and effectiveness of the InnAVasc arteriovenous graft (AVG) when implanted in and used for hemodialysis in participants suffering from end-stage renal failure (ESRD). The InnAVasc AVG is implanted and used similar to other standard-of-care dialysis grafts currently on the market. However, the InnAVasc AVG has been uniquely designed to potentially allow for immediate needle access (same day as implant surgery as opposed to 2-4 weeks of waiting), to potentially reduce excessive bleeding from the graft after dialysis, and it may provide protection from improper or missed needle cannulation attempts.

The ProActive registry is a longitudinal, multi-center study with a prospective arm observing clinical care for patients receiving physician ordered Prospera, an allograft rejection test, and a historical control arm collecting data on cases at the same sites whose kidney allograft rejection status was managed with Serum Creatinine SCr/estimated Glomerular Filtration Rate eGFR. This registry will compare patient management and outcomes in patients who receive Prospera (Prospera arm) to the outcomes of the historical control group (control arm) to determine Prospera's clinical utility. High-risk subjects defined as having a biopsy-demonstrated rejection event or at least one pre-existing Donor Specific Antibody DSA with total Mean Fluorescent Intensity MFI>3000 or a calculated Panel Reactive Antibodies cPRA>70% will be followed for an additional period up to 24 months in both the Prospera arm and historical control arm.
