Responsive Neurostimulation for Post-Traumatic Stress Disorder
open to eligible males ages 25-60
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.

Deep Brain Stimulation of the Amygdala for Combat Post-Traumatic Stress Disorder
open to eligible males ages 25-70
Posttraumatic stress disorder (PTSD) affects approximately 30 % of American veterans returning from Iraq and Afghanistan. Although the current therapy is effective, a percentage of patients will fail to improve and will develop chronic treatment-resistant PTSD. Patients suffering from PTSD experience intense suffering, lack of productivity and a higher risk of suicide. Unfortunately, combat PTSD has a tendency to be resistant to current treatments. The central goal of this project is to develop a new therapeutic strategy involving the placement of intracranial electrodes to treat the symptoms of PTSD. The project is based on recent evidence showing abnormal activity in a specific brain region of PTSD patients, thought to be responsible for the core symptoms of PTSD.

Healthcare Providers as Trusted Messengers to Increase Receipt of Tax Credits Among Low-income Families
open to eligible people ages 18-99
The purpose of this study is to pilot test the feasibility, acceptability, and preliminary efficacy of healthcare provider referrals to a tax filing app within parent-child health programs to test whether such referrals can increase receipt of tax credits among low-income parents. The study will use a single-group, pre/post test design with a sample of approximately 100 women who have a child under 6 years of age. Participants will be recruited from parental-child health programs and clinics in Los Angeles and will complete surveys at baseline, immediately after tax filing season, and six months after tax filing season to assess 1) frequency of tax filing after referral (Feasibility), 2) the acceptability of the tax filing app from the perspective of users (Acceptability), and 3) pre/posttest changes to parent and child health, child development, and healthcare utilization measures for users (preliminary efficacy).

Insomnia Treatment and Cardiometabolic Health in Older Adults With Posttraumatic Stress Disorder
open to eligible people ages 50 years and up
This pilot randomized controlled trial will address a gap in knowledge related to addressing modifiable risk factors for cardiometabolic disease through treating residual insomnia, sleep difficulties that remain after successful treatment of another condition, in the context of PTSD in understudied older adults. This study provides a non-medication treatment for PTSD called Cognitive Processing Therapy (CPT) followed by one of two non-medication sleep education and treatment programs for sleep problems that remain after completing PTSD treatment in older adults with PTSD. The aims of this project are to evaluate 1) the added benefits of treating residual insomnia on sleep and PTSD symptoms; 2) the added benefits of treating residual insomnia following CPT on cardiometabolic risk biomarkers and quality of life; and 3) the durability of the sleep, PTSD, cardiometabolic and quality of life benefits of treating residual insomnia following CPT at 6-month follow-up in older adults with PTSD.

Mindful Self-Compassion to Address PTSD and Substance Use in Unhoused Women
open to eligible females ages 18 years and up
Trauma exposure, posttraumatic stress disorder (PTSD), and substance use disorder (SUD) present major threats to public health. PTSD and SUD are major correlates of disability, often resulting in severe social and occupational impairment. Comorbidity between PTSD and SUD (PTSD/SUD) is common and frequently co-occurs with other mental health ailments including depression, anxiety, and suicidality. Comorbidity may be amplified in groups vulnerable to high trauma exposure, such as women with low socioeconomic status including women experiencing homelessness (WEH). Moreover, the reciprocal nature of PTSD/SUD (substances are used to cope with PTSD symptoms; substance use can create high-risk situations for new traumas to occur), can create a cycle of trauma and symptomatology leading to a critical health disparity. PTSD/SUD can be costly and difficult to treat, with treatment completion often low and relapse rates often high. Low-cost, complementary interventions, such as self-compassion (SC) interventions, which target key mechanisms that maintain PTSD/SUD, could improve treatment outcomes. SC interventions include practices that build skills to improve emotional responses, cognitive understanding, and mindfulness. Recent research supports the benefit of SC interventions for reducing PTSD, SUD, and related comorbidities, potentially with large effects. However, sample sizes have generally been small and randomized designs infrequently used. Moreover, while SC interventions may act to improve key mechanisms of treatment response and/or symptom maintenance (e.g., emotion regulation/dysregulation, trauma-related guilt, trauma-related shame, moral injury, and craving), such mediating factors have been underexplored. To address these limitations, the present proposal will implement community-based research principles and use a two phase, mixed-method design to adapt and test a widely used SC intervention (Mindful Self Compassion; MSC) for use with a sample of WEH with PTSD/SUD. The project will be conducted in partnership with a state-funded drug treatment facility that serves women and families experiencing high health disparities. Phase I was completed in 2023 and adapted the standard MSC course for use with trauma-exposed WEH with PTSD/SUD using the ADAPT-ITT model, an eight-stage model that engages community partners to increase feasibility and acceptability of interventions for at-risk populations. Phase II will be an open-label cluster randomized clinical trial (N=202) to test the benefit of the adapted MSC at improving primary (PTSD, substance use) and secondary outcomes (depression, anxiety, hopelessness) among a sample of WEH with PTSD/SUD residing in a residential drug treatment site. MSC (n=101) will be compared to Treatment as Usual (TAU; n=101). WEH in the MSC group will complete a 6-week (six sessions plus a half-day retreat) MSC intervention. The TAU group will engage in weekly check-ins with the research team but will not receive an intervention. WEH will be assessed at baseline, immediately post-intervention, and at a 4-month follow-up. One-on-one interviews will be conducted with the MSC group to collect qualitative data on experiences. An exploratory aim will be to elucidate mechanism of treatment-response and maintenance or remission of PTSD symptoms. These potential mechanisms will include SC, emotion regulation/dysregulation, trauma-related guilt, trauma-related shame, moral injury, and craving. Results may inform treatment for PTSD/SUD in WEH and other groups experiencing high health disparities and provide valuable insights into mechanisms underlying PTSD/SUD symptoms over time. Findings are relevant to military populations, which experience high rates of PTSD/SUD, and other populations disproportionately exposed to trauma.

Resources, Inspiration, Support and Empowerment (RISE) for Black Pregnant Women
open to eligible females ages 18-65
Perinatal Mood and Anxiety Disorders (PMADs) encompass a range of mental health disorders that occur during pregnancy and up to one year postpartum. Approximately 13% of women experience PMADs. This rate doubles for those with adverse perinatal outcomes (APO) and triples in Black women. Recent research points to racism as one significant source of these health disparities. Cultural adaptations to improve communication with providers decrease rates of depression in minority patients as well as improve adherence to treatment, insight and alliance. Discrimination stress and worries about experiencing medical consequences are thought to increase systemic inflammation, a mechanism known to drive mental and physical symptoms. Inflammation has been implicated in both PMADs and APO, suggesting a shared underlying etiology. Evidence from our work suggests that inflammation contributes to the pathophysiology of PMADs. The proposed pilot randomized control trial will allow the investigators to build on promising preliminary results and identify whether our culturally relevant mobile Health (mHealth) intervention is effective in improving outcomes among Black pregnant women randomized to the intervention compared to a control group. The culturally relevant modules include building communication and self-advocacy skills and provide a support network. The primary objective of this research is to provide guidance for clinical care of Black women during the perinatal period, with the goal to improve mental health and physical health outcomes. A secondary goal is to examine novel inflammatory signatures that change as a function of the intervention to reduce PMADs in this population. As inflammation may be diagnostic of PMADs, identification of its role may shed light of potential intervention targets and provide critical knowledge to improve women's long-term health. PMAD symptoms will be assessed prospectively in 150 Black pregnant women, half of whom will be randomized to receive the culturally relevant mHealth intervention. The investigators hypothesize that women in the intervention group will have reduced rates of PMADs and APOs, an increase in adherence to mental health treatment and will report increased self-advocacy skills, increased communication with providers, and reduced levels of discrimination related stress. Participants will also have improved biological risk indicators including lower circulating C-reactive protein and a transcription profile of differentially expressed inflammatory genes, marked by a decreased activity of inflammatory transcription factors from blood spots. Given the high burden of both PMADs and APOs among Black mothers and the numerous consequences on maternal and child outcomes, it is imperative that investigators develop and implement effective interventions, and test the biological mechanisms that might drive these effects. This work is interdisciplinary, building on a network of community advocates to implement a novel mHealth intervention informed by real world experiences designed to enhance self-advocacy, reduce stress and prevent adverse outcomes

Discrimination and the Brain-Gut-Microbiome (BGM) Axis
open to eligible females ages 18-50
Obesity is a major public health problem related to a variety of illnesses such as heart disease and diabetes. Prior research indicates that social stressors contribute to risk for obesity, possibly through alterations in diet and physical activity. However, it is not fully clear how these alterations contribute to obesity. The purpose of this study is to examine how the stressors of social isolation and discrimination relate to eating behaviors and dietary patterns, and further, how these behaviors affect the brain-gut-microbiome (BGM) connections. This study will focus on Mexican and Filipina women because research shows that they encounter a high burden of obesity and exposure to social stressors. Approximately 300 Mexican and Filipina women will be screened and enrolled. They will then provide information about social stressors via food diaries, physical body measures (e.g. waist circumference), questionnaire data regarding diet and eating behaviors, and measures of physical activity. Stool and serum will be collected to analyze microbes and metabolomics, and MRI to assess brain changes in the reward network. Analytic techniques will be used to integrate data from these multiple data sources. This analysis will determine the unique differences associated with ethnicity and social stressors in moderating eating behaviors and dietary patterns. The results of this study will provide new information about a possible pathway whereby social stressors affect behavioral, neurological and microbiome mechanisms related to obesity risk and provide new information in BGM patterns in two understudied ethnic groups. In the long term, this research may suggest possible approaches for intervention that may help reduce inequalities in obesity and related health problems.

Adaptation of the PCIP for Children Aged 6 to 11
Sorry, currently not accepting new patients, but might later
This study will implement a brief Post-traumatic Stress Disorder (PTSD) intervention for children, the Primary Care Intervention for PTSD (PCIP) delivered through telehealth (computer or smartphone delivery), to 10 youth age 6-11 and their caregivers. Mixed methods (qualitative and quantitative) randomized pilot feasibility trial (n=10 to treatment and 10 to waitlist control) to refine the intervention, study procedures, and explore effectiveness. Following RE-AIM guidelines, the investigators will assess: 1. Reach: patient participation in intervention delivery (out of all those asked to participate) and retention rate (out of all those who consented to participate and completed at least two intervention sessions) 2. Adoption: patients and their parents/guardians will complete screening and intervention satisfaction ratings. To understand patient experiences with the intervention and to identify and explain positive or negative treatment mechanisms or effects, the investigators will conduct post-intervention semi-structured interviews with the participating patients, their parents/guardians, and with providers. This treatment ranges from 1-4 sessions which last 50 minutes per session. The first session will cover psychoeducation about PTSD symptoms in children that can be delivered to the parent or both the parent and child. The first session will also teach the parent and child a breathing technique to combat the physiological impact of PTSD in children. The subsequent sessions will be tailored to meet the needs of the child's most distressing PTSD symptom cluster including hyper arousal, negative changes in cognition and mood, avoidance, re-experiencing. Each session contains coping skills that the parent and child can learn together. There is also material for parents to address behavior problems in youth. This treatment will be delivered via telehealth.

Adolescent PCIP Randomized Feasibility Trial
Sorry, currently not accepting new patients, but might later
There are three research questions: (1) whether the Primary Care Intervention for PTSD (PCIP) improves health outcomes; (2) whether and how the PCIP can be sustainably delivered via telehealth; and (3) how PCIP compares to treatment as usual (TAU) participants. The mixed methods randomized feasibility trial of the protocol will be measured by the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance) (n=44 patients and their care givers). We will collect data on patient, caregiver, and clinic staff participation, retention, and satisfaction (Reach and Adoption), change in hypothesized treatment mechanisms and symptoms (Effectiveness), and facilitators and barriers to intervention delivery and fidelity (Implementation). We will, 1. Assess the reach and adoption of the protocol by analyzing quantitative data on patient and clinic staff participation, retention, and satisfaction; 2. Explore the effectiveness of the protocol through medical record review, quantitative assessments at baseline and post-treatment, and semi-structured qualitative interviews at baseline and post-treatment to: 3. Evaluate the implementation of the screening and intervention protocol with post-intervention semi-structured qualitative interviews to assess facilitators and barriers to intervention delivery, quantitative fidelity scales, observation of screening, and review of intervention audio recordings to assess fidelity to the protocol and intervention process.

Daily Blood Glucose Trends in Patients at Risk for Diabetes
Sorry, not yet accepting patients
The goal of this study is to learn about the relationship between blood sugar, diet, stress, and metabolic parameters including waist circumference, body mass index (BMI), cholesterol levels and blood pressure in patients at risk for diabetes. The main questions it aims to answer are 1) are there trends in blood sugar responses after meals for patients at risk of developing diabetes? And 2) are there correlations between stress and fluctuations in blood sugar? During the first visit, participant's waist circumference, body composition, cholesterol, and resting blood pressure will be measured, and a continuous glucose monitor sensor will be placed on the participant's non-dominant arm. This sensor will be worn for seven days, and the participant will be asked to complete a daily food log during that time. Each participant will be asked to return to clinic after one week to return the continuous glucose monitor and daily food log.

Sorry, in progress, not accepting new patients
The goal of this randomized control trial is to learn if professional coaching can help reduce physician burnout among physicians at UCLA. The main aims of the study are: - To reduce burnout among physicians with professional coaching - Improve work satisfaction and engagement, sense of self-efficacy and social support with professional coaching - Determine the efficacy of one-on-one professional coaching and small group professional coaching combined with behavioral interventions/activities in reducing physician burnout and comparing these groups to one another and to a delayed-entry (control) group Participants will be randomly assigned into one of three groups: - Intervention Group 1: One-on-one coaching (N=30). Six one-on-one coaching sessions via Zoom with one of two private professional coaches every other week for 3-4 months. - Intervention Group 2: Coach-facilitated group sessions and coach-guided activities/behavioral interventions (N=30). Six small-group coaching sessions via Zoom with one of two private professional coaches and three physician participants in each group, every other week for 3-4 months. - Delayed-Entry Group 3 (N=30): No intervention during duration of study period. Note: once participation in the pilot study has been completed for Groups 1 and 2, physicians participating in Group 3 will be offered to participate in six one-on-one sessions with a private professional coach over a 3-4 month period. Participants will complete several surveys that assess for burnout, work engagement and satisfaction, sense of social support and isolation, and areas of worklife) before the start, upon completion of the intervention and again at 6 months upon completion of the sessions for the delayed-entry group. Each group also received coach-guided activities/behavioral interventions during coaching sessions. These activities will be sent by coaches to participates throughout the 3 month period and include, but are not limited to: Wheel of Life, visioning exercise, one page miracle: core values, purpose, and goals, buckets and mental models.

Personalized Brain Stimulation to Treat Chronic Concussive Symptoms
Sorry, not yet accepting patients
The goal of this study is to investigate a new treatment for chronic symptoms after concussion or mild traumatic brain injury in people aged 18-65 years old. Chronic symptoms could include dizziness, headache, fatigue, brain fog, memory difficulty, sleep disruption, irritability, or anxiety that occurred or worsened after the injury. These symptoms can interfere with daily functioning, causing difficulty returning to physical activity, work, or school. Previous concussion therapies have not been personalized nor involved direct treatments to the brain itself. The treatment being tested in the present study is a noninvasive, personalized form of brain stimulation, called transcranial magnetic stimulation (TMS). The investigators intend to answer the questions: 1. Does personalized TMS improve brain connectivity after concussion? 2. Does personalized TMS improve avoidance behaviors and chronic concussive symptoms? 3. Do the improvements last up to 2 months post-treatment? 4. Are there predictors of treatment response, or who might respond the best? Participants will undergo 14 total visits to University of California Los Angeles (UCLA): 1. One for the baseline symptom assessments and magnetic resonance imaging (MRI) 2. Ten for TMS administration 3. Three for post-treatment symptom assessments and MRIs Participants will have a 66% chance of being assigned to an active TMS group and 33% chance of being assigned to a sham, or inactive, TMS group. The difference is that the active TMS is more likely to cause functional changes in the brain than the inactive TMS.

Stress & Resilience Study
Sorry, in progress, not accepting new patients
Goal 1: The investigators will quantify lifetime stress burden and examine mechanisms linking Adverse Childhood Experiences (ACEs) and health. The investigators will quantify the early life and total lifetime stress burden of a representative sample of about 725 adults (aged 18+) across northern and southern California. In addition, the investigators will examine how prior life stress exposure and current stress levels are associated with differences in psychosocial, immune, metabolic, physiologic, and clinical outcomes for all participants at baseline. Goal 2: The investigators will develop and test a biopsychosocial intervention using existing programs, platforms, resources, and core components from trauma and resilience research that will target five stress-related domains (i.e., cognitive response style, social relationships, eating, sleep, and physical activity) using cognitive restructuring and mindfulness, interpersonal skills training, mindful eating training, sleep training, and behavioral activation/mobility training. The investigators will then assess the efficacy and acceptability of the intervention in about 425 high stress exposure participants from Goal 1. Following their baseline assessment, about 425 participants will be randomly assigned to receive for 12 weeks (a) personalized intervention, (b) environmental education (active control) or (c) nothing (non-active control). The investigators will also assess the efficacy of the personalized intervention by comparing changes in outcomes by condition from baseline (prior to randomization) to immediately after the intervention, and then again after 12 weeks following intervention completion. The interventions will be entirely online/remote.
