The overall objective of this in-lab randomized controlled trial is to test the efficacy of multi-day interruptions in sedentary behavior vs. single bouts of sustained exercise on metabolic, cognitive, affective, and cardiac autonomic nervous system responses in children with overweight and obesity who are at risk for type 2 diabetes. The use of continuous glucose monitoring will provide insight into the daily and cumulative metabolic effects of each condition that have thus far not been studied. In-lab studies demonstrating sustained efficacy of this approach in ameliorating negative effects of sedentary behaviors in children are necessary for the optimization of field-based interventions. Given the lack of success of interventions to prevent obesity-related diseases and increasing rates of type 2 diabetes in children and its related healthcare costs, this study addresses a critical public health need by testing of novel intervention strategies to reduce obesity-related diseases in children with overweight and obesity.

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.

Growing up in a lower-income family robustly predicts worse mental health in adolescence and early adulthood. How does variability in family income "get under the skin" of the developing child and via what mechanisms does it increase risk for mental illness? Moreover, could supplements to family income at critical developmental periods help to prevent later youth mental illness? To address these questions, we leverage an innovative existing double blind randomized controlled trial of 3-years of substantial income supplements to parents. By experimentally studying the impacts of these income supplements on families and subsequent youth development, we can examine causal pathways from family income to risk for mental illness via family stress and neuroimmune mechanisms in ways never done before. Moreover, by measuring the longer-term impact of 3 years of income supplements to parents on their child's neuroimmune signaling and risk for mental illness, we can examine the policy implications for child development of unconditional cash transfers to parents and identify how and for whom these supplements help. We will test these basic and translational questions in a sample of 1,200 youth with lower-income parents randomly assigned to receive either a substantial monthly income supplement or a minimal monthly supplement for 3 years, starting when youth were between age 5 - 14 years old. We will follow up with youth and their parent 1 - 2 and 3 - 4 years after the intervention and examine whether income supplements predict better youth mental health during adolescence, as well as whether factors like child age and neighborhood quality modulate intervention effects. Additionally, we explore family stress mechanisms through which the intervention may impact child mental health. Finally, we will measure peripheral inflammation (inflammatory biomarkers and classical monocytes) and use MRI to assess threat, reward, and regulatory neural activity and connectivity among 500 of these youth. Our central hypothesis is that income supplements will decrease family and youth stress and improve parenting, which will improve neuroimmune signaling and decrease risk for psychopathology. Moreover, these effects will remain years after termination of the transfers and be strongest among families who received the intervention earlier in the child's life. This research will provide timely, relevant public health knowledge that will help policy makers understand the longer-term brain, immune, and mental health impacts of cash transfers to parents, while also advancing the science of the sociocontextual and neuroimmune pathways through which variability in family income impacts risk for psychopathology.

This project is part of the NIH Helping to End Addiction Long-term (HEAL) initiative (https://heal.nih.gov/). This randomized controlled trial (RCT) is phase 2 of a two-phase, 5-year project with the overarching goal of testing a decision aid (DA)/coaching intervention, tailored to Black patients with comorbid chronic pain and depression, to encourage use of and adherence to nonpharmacological pain treatments (NPTs). This 2-arm trial will randomize 304 patients with comorbid chronic musculoskeletal pain and depression in primary care from an urban safety-net health system (Eskenazi). After the baseline assessment, patients randomized to the intervention will be asked to participate in 4 coaching sessions over approximately 12 weeks. Sessions will use Motivational Interviewing principles to foster openness to NPTs and self-efficacy by helping patients identify their goals and priorities, understand their NPT options, prepare them to discuss and choose options with their primary care providers (PCPs), and reinforce these choices to foster maintenance of these changes. DA contents will be integrated into these sessions, which will facilitate discussion of these options with their PCP. The first 3 sessions take place prior to the patient's next scheduled PCP visit; the final session occurs after this visit. Assessments will be conducted at baseline, 3 months (i.e., after completing the final coaching session), and 6 months. Patients randomized to the wait-list control group will receive usual care (in addition to study assessments at baseline, 3 months, and 6 months). After completing the final assessment, they will then be given the DA and offered a 20-minute coaching session to walk them through it.

In the U.S., legal cannabis is frequently advertised as an effective treatment for mental health problems such as anxiety and depression-particularly online. States that have legalized cannabis have not implemented regulations to address this type of advertising. This project aims to investigate the influence of psychotherapeutic advertising claims (PAC) and mental health warning labels (WL) on online cannabis purchasing behaviors among light-to-moderate cannabis users with symptoms of depression and/or anxiety. The specific aims are to determine whether PAC increases cannabis purchasing intentions and whether a mental health WL can mitigate this effect. A realistic online cannabis shopping experience will be simulated using the digital Platform for Online Evaluation of Marijuana Marketing and Sales (POEMMS). The study will employ a between-subjects experimental design by randomizing 2,000 participants to one of four online stores that vary in PAC and WL content: (1) a control claims (CC)-only store, (2) a PAC store, (3) a WL store, and (4) a PAC + WL store. Participants will browse and select items as if making real purchases. Analyses will examine three primary outcomes to determine the influence of PAC and WL on purchasing behaviors: (1) total milligrams of THC purchased, (2) average potency (%THC) of products, and (3) overall number of products purchased. The long-term objective is to inform evidence-based cannabis policy and regulatory strategies by understanding the impact of cannabis marketing on vulnerable populations. This research is relevant to public health by addressing the potential risks associated with misleading cannabis marketing, which may lead to increased use and exacerbation of mental health symptoms among individuals with depression and anxiety. The project leverages a multidisciplinary team with expertise in addiction, mental health, epidemiology, and digital health technology. The findings have the potential to inform the development of targeted interventions and policies to reduce harms associated with cannabis advertising-ultimately contributing to better health outcomes and more effective regulation.

This phase II trial tests the safety and side effects of psilocybin in combination with therapy for the treatment of major depressive disorder in patients with non-small cell lung cancer. A cancer diagnosis is life-changing, resulting in significant levels of psychological symptoms, including a combination of depression, anxiety, stress, including feelings of existential distress (i.e., loss of meaning, demoralization, despair). Among all cancer patients, those diagnosed with lung cancer have the highest prevalence of mood disorders, such as depression (up to 40%) leading to profound deterioration in quality of life, prolonged hospital stays, poorer treatment adherence, decreased survival rates, and high rates of suicide (5- and 3-times higher than the general population and other cancer patients, respectively). Psilocybin is substance being studied in the treatment of anxiety or depression in patients with advanced cancer. It is taken from the mushroom Psilocybe mexicana. Psilocybin acts on the brain to cause hallucinations (sights, sounds, smells, tastes, or touches that a person believes to be real but are not real). Psilocybin in combination with therapy may be safe and effective in treating major depressive disorder in patients with non-small cell lung cancer.
