Approximately one in two individuals with bipolar disorder (BD) are non-adherent with medication, often leading to severe and negative consequences. Unfortunately, there is no widely used evidence-based approach to target poor adherence among individuals with BD. Building upon positive efficacy trial results, the proposed project will test the effectiveness of technology-facilitated Customized Adherence Enhancement (CAE) vs. enhanced treatment as usual (eTAU) using a prospective randomized controlled design in public mental health care settings and preferentially enrolling poorly adherent/high-risk individuals with BD. Deliverables include a curriculum-driven adherence enhancement approach that can be implemented in public healthcare settings and which can improve outcomes for the most vulnerable groups of people with BD.

The goal of this clinical trial is to test the effectiveness of a Smart Bassinet to prevent/mitigate postpartum mood disorders by augmenting maternal sleep and/or enhancing infant sleep. The investigators will conduct a 2-arm randomized controlled trial (RCT) to compare infant and maternal sleep of infants who use a smart bassinet (SB) or a standard commercially available bassinet (Halo Bassinest Swivel Sleeper 3.0) (usual/traditional care (TAU)). After confirmation of eligibility, participants (N = 342) will randomly be assigned to either the SB or TAU. The investigators hypothesize that use of the SB will be associated with better infant and maternal sleep over a 6-month period, and these mothers will report fewer depressive and anxiety symptoms across the postpartum. The main question[s] it aims to answer [is/are]: Aim 1: Determine the effect of the SB on infant sleep and maternal sleep. [primary hypothesis or outcome measure 2]? Aim 2: Determine the effect of the SB on maternal postpartum depressive symptoms and evaluate the model that the association between the SB and postpartum depressive symptoms is mediated by both infant and maternal sleep Aim 3: Compare trajectory of immune system function from late pregnancy through postpartum between PPD and non-PPD and between SB and TAU groups Exploratory Aim. Evaluate whether the elevated risk demonstrated by previously identified PPD epigenetic biomarkers at the TTC9B and HP1BP3 genes can be modified by using a SB. The investigators hypothesize that the elevated risk will be reduced in the SB condition compared to TAU. Military-affiliated pregnant women will be recruited from across the US via social media and advertising. Monthly online questionnaires will be completed by the mother. Objective sleep data will be collected monthly using an actigraph for 1-week from both mother and baby. Blood samples for assay of inflammatory markers will be collected at enrollment, 3- and 6- months postpartum.

Although multiple treatments for OCD exist, slow symptom decrease, high remission, and significant side effects for some OCD patients limit their efficacy. More research into the precise neural mechanisms and linked cognitive functions in OCD is also necessary. To address both concerns, this study by Dr. Reinhart and his team will test a new, non-invasive, and well-tolerated neuromodulation method for reducing OCD symptoms, based on reward-related rhythms of the orbitofrontal cortex (OFC; a brain region responsible for reward, decision making and other crucial functions that is affected by OCD). This proposal is based on highly encouraging preliminary data in both subsyndromal and treatment-resistant populations that shows rapid reductions in OCD behaviors that last at least 1-3 months. Using high-definition transcranial alternating current stimulation (HD-tACS) guided by EEG brain wave recordings, the study will test whether repetitive modulation of relevant rhythm activity in the OFC can lead to rapid (within five days) and sustainable (up to three months) OCD symptom reduction. This research aims to increase knowledge of OCD and development of effective treatment with minimal side effects.

Spinal interoceptive pathways (SIPs) convey bodily signals to an interoceptive system in the brain and their dysregulation is linked to major depressive disorder (MDD). Current treatments are partially effective and the role of SIPs in MDD is vastly unexplored. Preliminary data suggests that SIPs are feasible therapeutic targets in MDD. The central hypothesis is that non-invasive spinal cord stimulation will modulate SIPs to elucidate their role and therapeutic potential in MDD using an R61/33 phased innovation approach. R61 phase specific aims (SA). The specific goal will be to evaluate spinal and brain-based SIPs target engagement markers of transcutaneous spinal direct current stimulation (tsDCS) in MDD with two SAs: SA1) To determine tsDCS SIPs modulation using laser-evoked potentials (LEPs) as electroencephalography (EEG)- based neural measures of target engagement. SA2) To evaluate optimal tsDCS dose based upon tolerability and SIPs target engagement markers. Anodal tsDCS will be evaluated as a tool to modulate SIPs in MDD. SIPs (Aδ and C fibers) can be evaluated via LEPs as neural measures (EEG) elicited in MDD-relevant brain regions within an interoceptive system. Prior data shows anodal tsDCS inhibits SIPs and LEPs N2 component will be assessed as tsDCS engagement markers. Adults with MDD (n=67) will participate in a double-blind, crossover, sham-controlled study to evaluate tsDCS at 0,2.5,3, and 3.5 mA. The working hypothesis is that tsDCS will induce a change in LEPs (SA1) in a dose-dependent and tolerable manner (SA2), supporting their use as SIPs engagement markers. Go/No-Go milestones: Compared to sham, the active tsDCS dose that induces a change in LEPs at a preestablished threshold will be evidence of SIPs engagement and "Go" criteria for the R33 phase.
