In this research study, investigators examine how brain activity changes during tests of emotional processing, attention, and memory using multimodal neuroimaging methods including electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS). Transcranial magnetic stimulation (TMS) is used to probe and modulate brain networks related to cognitive flexibility and emotion regulation. The study includes multiple related sub-studies involving healthy participants and participants with depression. Some study components focus on mechanistic modeling using non-therapeutic neurostimulation in healthy participants, while other components include interventional approaches such as individualized EEG-synchronized repetitive TMS (rTMS), cognitive tasks, and brief cognitive behavioral therapy (CBT) in participants with depression. Certain study components also evaluate CBT alone without TMS to assess behavioral intervention effects.

The investigator's long-term goal is to mitigate pregnancy-related mortality (PRM) risk by systematically delivering scalable integrated clinical and supportive care that is effective for all. The investigator's central hypothesis is that the Multi-modal Maternal Infant Perinatal Outpatient Delivery System (MOMI PODS) will mitigate postpartum (PP) risk for all by increasing patient engagement with evidence-based cilnical and supportive care, thus improving biopsychosocial profiles that drive clinical risk. To test this hypothesis, the investigators will conduct a hybrid type 1 randomized controlled trial (RCT) of MOMI PODS versus enhanced usual care (EUC, which we will term MOMI CARE) among a total sample of up to 384 mother-infant dyads (192/group) following pregnancy affected by a cardiometabolic and/or mental health condition. The investigators will enroll participants during late pregnancy and collect data at baseline and 6 months and 1 year PP. The investigators will collect implementation and service data across sites.

The primary goal of this clinical trial is to evaluate the unique neural and behavioral effects of a one-session training combining emotion regulation skills training, with excitatory repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (dlPFC). The secondary aim is to identify key changes in the emotion regulation neural network following the combined intervention versus each of the components alone. The third aim is to explore personalized biomarkers for response to emotion regulation training. Participants will undergo brain imaging while engaging in an emotional regulation task. Participants will be randomly assigned to learn one of two emotion regulation skills. Participants will be reminded of recent stressors and will undergo different types of neurostimulation, targeted using fMRI (functional MRI) results. Participants who may practice their emotion regulation skills during neurostimulation in a one-time session. Following this training, participants will undergo another fMRI and an exit interview to assess for immediate neural and behavioral changes. Measures of emotion regulation will be assessed at a one week and a one month follow up visit.

This study explores whether participating in an 8-week Brazilian Jiu-Jitsu (BJJ) program is linked to changes in trauma-related symptoms among first responders. Many first responders experience ongoing stress or exposure to traumatic events, and some prefer physical, movement-based activities rather than traditional clinical services to support their well-being. In this study, participants will attend BJJ classes one to two times per week for eight weeks. They will also complete short daily and weekly questionnaires about mood, stress, and well-being, write brief weekly reflections, and participate in a one-on-one interview after the program. The study aims to understand both symptom patterns and participants' personal experiences with emotional regulation and overall wellness during the program. This study does not provide mental health treatment and will not diagnose or treat PTSD. Instead, it examines whether BJJ, as a non-clinical physical activity, may offer supportive benefits for first responders.

Veterans with co-morbid posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) are at substantial risk of developing hypertension and cardiovascular diseases that often lead to premature death, with some evidence that they may die over 10 years earlier than their counterparts. As such, determining ways to improve their health outcomes is vital. Heart Rate Variability Biofeedback (HRVB) may be one way to restore autonomic balance and teach veterans with PTSD / SUDs how to respond differently to their symptoms. Multiple studies have found that HRVB not only improves autonomic nervous system (ANS) regulation / flexibility among veterans with PTSD, but also reduces PTSD symptoms. Additionally, there is evidence that HRVB reduces cravings and SUD symptoms. Currently it is proposed that the improvement in the PTSD and SUD symptoms are due to a combination of improving ANS regulation and veterans utilizing the HRVB techniques as coping strategies for their symptoms. Yet, none of these studies examined how HRVB versus other active interventions differentially effected symptoms and physiological outcomes. It may be useful to examine HRVB to other active interventions . The current project proposes to alleviate this gap by examining the effects of HRVB to one a active control condition (i.e., Present Centered Psychotherapy; PCT) among 50-residential veterans engaging in PTSD residential programming. Veterans will be recruited from residential programs at the Coatesville VAMC and screened for probable PTSD and an active (i.e., past year) SUD. If eligible, they will attend a brief visit that will include being randomized, engaging in a diagnostic interview, a battery of questionnaires related to PTSD / SUDs, attached to physiology equipment, and then complete 3 tasks (i.e., baseline task, emotion induction, and HRVB or Self-Compassion Break). Upon task completion, all veterans will be screened for risk and begin one of the conditions. Similar research procedures will be conducted after their final session. This study would provide evidence for the real-world effectiveness of HRVB compared to a control condition among one of the highest risk populations treated at the VA, which may provide invaluable insight into active mind-body treatments for veterans with PTSD / SUD.
