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.

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.

Postpartum depression (PPD) occurs almost as often among men as it does among women. However, while there have been multiple programs designed to prevent maternal PPD, few, if any, interventions exist that have been created specifically to prevent paternal PPD. After engaging in evidence-based qualitative research with soon-to-be or new fathers, a novel interpersonal-therapy based digital program was created to prevent paternal PPD called Together in Parenting (TIP), which comprises multiple podcasts and digital educational handouts. The proposed pilot study will examine the feasibility and acceptability of using TIP as a paternal PPD intervention, will determine the optimal timing of administering TIP to future/new fathers, and will generate preliminary estimates of effect of the intervention to support a future efficacy study.
