Post-traumatic stress disorder (PTSD) refractory to treatment is marked by failure of fear extinction and its biological substrate, amygdala reactivity to trauma reminders. Decades of research have clarified the neuronal mechanisms coordinating fear extinction and consolidation. Fear cells and extinction cells in the basolateral amygdala (BLA) alter their firing rate based on the nature of the stimulus and the influence from the medial prefrontal cortex (mPFC) and the ventral hippocampus (vHPC). Together, the BLA, mPFC, and the vHPC form an anxiety-processing network where the BLA links stimulus to emotion, the vHPC provides memory context, and the mPFC coordinates extinction or consolidation. Local field potential (LFP) recordings from the BLA have revealed specific signals that correspond to an enhanced fear state. Previous studies have shown that neuromodulation of the BLA can promote extinction in a rodent model and in a treatment-refractory PTSD patient. This action is likely carried by disrupting fear signals within the BLA; however, continuous neurostimulation may also disrupt normal function of the amygdala. The present application proposes to investigate the use of Responsive Neurostimulation (RNS, Neuropace) in six (6) veterans suffering from severe treatment-resistant PTSD. This dual-activity device will allow us to chronically record LFPs from the BLA under specific conditions such as fear conditioning, exposure to trauma reminders, and emotional memory encoding and retrieval. In addition, the neural activity will be captured during real-life symptoms of flashback and nightmares. These recordings will provide the specific electrophysiological biomarkers of hypervigilance and re-experiencing. The device will then be programmed to detect and treat these biomarkers with a pre-determined electrical pulse. The patients will be followed prospectively using psychological scales but also with functional neuroimaging and electroencephalograms. These modalities will be used to determine the extent of circuit engagement as a result of the therapy. By approaching PTSD from a fear processing mechanism perspective, our project will serve as a proof of concept for other circuit-based therapies in psychiatry. This proposal is a multi-departmental effort involving 11 investigators across 7 departments and requires a close collaboration between clinical and basic scientists. As a result, the findings underlying chronic recordings will bridge the basic science results from fear conditioning research to clinical neural processes in PTSD patients. Read Less

This research study aims to test a financial and health insurance iHERO Toolkit for young adults with type1 diabetes. The iHERO Toolkit was developed over one year with the type 1 diabetes community, The Diabetes Link organization, and experts. Now, the investigators want to understand the impact of the iHERO Toolkit on diabetes self-management, financial stress, and health insurance literacy outcomes. The investigators are doing this study because it will help to better understand how to support health insurance and financial stress and improve self-management outcomes in young adults with type 1 diabetes. The investigators want to understand how the iHERO Toolkit helps all young adults with diabetes, but especially those on Medicaid and who are racially or ethnically diverse. The investigators will ask participants to participate at four-time points over one year. For the first time, participants will fill out online enrollment and demographic forms and 9 surveys. The 9 surveys have 8-40 short questions each, estimated to take about 45 minutes. Participants will also be asked to complete a home A1c collection with a University Hospitals team member on Zoom.

The objective of this prospective, randomized, blinded clinical trial is to assess the safety and efficacy of the Carillon Mitral Contour System in treating heart failure with functional regurgitation (FMR). Read Less

This is a Phase 4 study with 2 parts: Part 1 (Prevalence Phase) is non-interventional and will assess the prevalence of hypercortisolism in a population with difficult to control type 2 diabetes (T2D) (hemoglobin A1c ≥7.5%) despite receiving standard-of-care therapies. Part 2 (Treatment Phase) is a randomized, prospective, placebo-controlled, double-blind multi-center trial that will assess the safety and efficacy of mifepristone treatment in patients with hypercortisolism who have difficult to control T2D despite receiving standard of care therapies.
