Co-Regulation as a Support for Older Youth in the Context of Foster Care: a Scoping Review of the Literature.

Co-regulation is a relatively new theoretical framework for interventions that connects developmental science to adolescent needs and provides strategies that can be applied across contexts. It also has value in shifting the focus of interventions to the role of relationships and interactions with caring adults, as well as supportive environments. This framework may be particularly salient for older youth with foster care experience whose relationships with adults and availability of developmental supports are disrupted. To understand how co-regulation aligns with current understanding of needs and supports for this population, we conducted a scoping review that involved systematically searching four databases, coding and charting relevant information, and actively engaging expert consultants and other stakeholders. Across 46 primarily descriptive articles, co-regulation was discussed most often in relation to relationships, as expected (89% of articles). Despite theoretical and empirical evidence of the benefits of supportive environments and intentional day-to-day interactions in promoting developmental skills and competencies, these two domains of co-regulation were referenced much less (39% and 28%, respectively). Results highlight opportunities for co-regulation supports that can be provided to older youth with foster care experience by caring adults and near-aged peers in a wide range of roles. Notable limitations in the literature were identified in applying co-regulation within the context of employment and career readiness, healthy relationships, and teen parenting. Also under-researched is the role of adult self-regulation skills and co-regulation approaches for youth from diverse backgrounds, including those who identify as LGBTQ or have disabilities. Considerations for practice and future research are provided.

The microbiota-gut-brain axis and perceived stress in the perinatal period.

Perinatal perceived stress can contribute to worse health outcomes for the parent-child dyad. Given the emerging relationship between the microbiota-gut-brain axis and stress, this study sought to elucidate connections between bowel symptoms and the gut microbiome in relation to perceived stress at three time points in the perinatal period: two during pregnancy and one postpartum. Ninety-five pregnant individuals participated in a prospective cohort study from April 2017 to November 2019. Researchers assessed Perceived Stress Scale-10 (PSS); bowel symptoms (according to the IBS Questionnaire); psychiatrist assessment of new onset or exacerbated depression and anxiety; and fecal samples analyzed for alpha diversity (measures of gut microbiome diversity utilizing Shannon, Observed OTUs, and Faith's PD) at each timepoint. Covariates included weeks of gestation and weeks postpartum. PSS scores were divided into "Perceived Self-Efficacy" and "Perceived Helplessness." Increased gut microbial diversity was associated with decreased bowel symptoms, decreased overall perceived stress, increased ability to cope with adversity, and decreased distress in the postpartum period. This study found a significant association between a less diverse microbial community, lower self-efficacy early in pregnancy, and greater bowel symptoms and perceived helplessness later in the perinatal period, relationships that may ultimately point to novel diagnostic methods and interventions for perceived stress based on the microbiota-gut-brain axis.

Cross-continental collaboration for understanding postpartum major depression with psychotic features.

Purpose: Assess postpartum depression and psychotic symptoms from three continents. Methods: Compare numbers of women with depression and psychotic symptoms, mania with or without psychotic features, or transient non-affective psychosis and medication choice. Results: The prevalence of postpartum depression and psychosis and treatment choice differed at each site. Conclusions: Best treatment for postpartum depression with psychotic features has not been established yet. Cross-continental collaboration with similar assessments holds promise to develop best practices for these high risk mother-infant dyads.

App-Based Ecological Momentary Assessment to Enhance Clinical Care for Postpartum Depression: Pilot Acceptability Study.

BACKGROUND: Wearable tracking devices and mobile health technology are increasingly used in an effort to enhance clinical care and the delivery of personalized medical treatment. Postpartum depression is the most frequently diagnosed complication of childbirth; however, significant gaps in screening and treatment remain. OBJECTIVE: This study aims to investigate the clinical utility, predictive ability, and acceptability of using ecological momentary assessment to collect daily mood, sleep, and activity data through the use of an Apple Watch and mobile app among women with postpartum depression. METHODS: This was a pilot study consisting of 3 in-person research visits over the course of a 6-week enrollment period. Questionnaires to assess depression, anxiety, and maternal functioning were periodically collected, along with daily self-reported symptoms and passively collected physiological data via an Apple Watch. Feedback was collected from study participants and the study clinician to determine the utility and acceptability of daily tracking. Logistic regression was used to determine whether mood scores in the 2 weeks before a visit predicted scores at follow-up. Compliance with daily assessments was also measured. RESULTS: Of the 26 women enrolled, 23 (88%) completed the 6-week study period. On average, the participants completed 67% (34.4/51.5 days) of all active daily assessments and 74% (38/51.5 days) of all passive measures. Furthermore, all 23 participants completed the 3 required visits with the research team. Predictive correlations were found between self-reported mood and Edinburgh Postnatal Depression Scale score at follow-up, self-reported anxiety and EDPS, and sleep quality and Edinburgh Postnatal Depression Scale. CONCLUSIONS: Using ecological momentary assessment to track daily symptoms of postpartum depression using a wearable device was largely endorsed as acceptable and clinically useful by participants and the study clinician and could be an innovative solution to increase care access during the COVID-19 pandemic.

Metabolite trajectories across the perinatal period and mental health: A preliminary study of tryptophan-related metabolites, bile acids and microbial composition.

Depression and anxiety during pregnancy and postpartum are common, but affected women differ in timing, trajectories, and extent of symptoms. The objective of this pilot, feasibility study is to analyze trajectories of serotonin and tryptophan-related metabolites, bile acid metabolites, and microbial composition, in relation to psychiatric history and current symptoms across the perinatal period. Serum and fecal samples were collected from 30 women at three times points in the perinatal period and assayed with LC-MS/MS and 16S sequencing respectively. We defined mean trajectories for each metabolite, clustered individuals by metabolite trajectories, tested associations between metabolites, and examined metabolite levels in relation to microbial composition. Findings of note include: (1) changes in kynurenine and the ratio of kynurenic acid to kynurenine from second trimester to third trimester were strongly associated with baseline primary and secondary bile acids. (2) Secondary bile acid UDCA and its conjugated forms were associated with lower bacterial diversity and levels of Lachnospiraceae, a taxa known to produce Short Chain Fatty Acids. (3) History of anxiety was associated with UDCA levels, but history of major depression was not associated with any of the bile acids. (4) There was a trend towards lower dietary fiber for those with history of anxiety or depression. Overall, our results reveal substantial temporal variation in tryptophan-related metabolites and in bile acid metabolites over the perinatal period, with marked inter-individual variability. Trajectories of TRP -related metabolites, primary and secondary bile acids, and the absence or presence of microbes that produce Short Chain Fatty Acids (SCFAs) considered in concert have the potential to differentiate individuals based on perinatal adaptations that may impact mental and overall health.

Addressing Barriers to Primary Care Screening and Referral to Prevention for Youth Risky Health Behaviors: Evidence Regarding Potential Cost-Savings and Provider Concerns.

Despite growing evidence and support for co-locating behavioral services in primary care to prevent risky health behaviors, implementation of these services has been limited due to a lack of reimbursement for services and negative perceptions among providers. We investigated potential to overcome these barriers based on new developments in healthcare funding and screening and referral to prevention (SRP) in primary care based on the Consolidated Framework for Implementation Research (CFIR), which could guide future SRP implementation strategies. To investigate the economic need for healthcare-based SRP, we quantified hospital charges to healthcare payors for services arising from adolescent risky behaviors (e.g., substance use, risky sex). Annual North Carolina (NC) hospital charges for these services exceeded $327 M (2019 dollars), suggesting high potential for cost savings if SRP can curb hospital services associated with risky behaviors. To investigate provider barriers and facilitators, we surveyed 151 NC pediatricians and 230 NC family therapists about their attitudes regarding a recently developed well-child visit SRP with family-based prevention. Both sets of professionals reported widespread need for and interest in the SRP but cited barriers of lack of reimbursement, training, and referrals to/from each other. Physicians, but not family therapists, reported concerns with poor patient or parent compliance. Many barriers could be resolved by co-locating family therapists in pediatric clinics to conduct well-child SRP. Our results support further research to develop business models for payor-funded SRP and CFIR-guided research to develop implementation strategies for primary care SRP to prevent adolescent risky health behaviors.

Improving Mental Health for the Mother-Infant Dyad by Nutrition and the Maternal Gut Microbiome.

Perinatal mood and anxiety disorders (PMAD) have significant negative impacts on mother and child, yet treatments are limited. Adequate nutrition during the perinatal period is essential to maternal and infant health, including maternal mental health and the child's neurologic and neuropsychiatric development. Nutrition holds promise to improve prevention and treatment of PMAD. The ability to manipulate the gut microbiota composition and structure through host nutrition and to harness the gut microbes for improved individualized nutrition may be an important new direction for prevention and treatment of PMAD, thus improving the mental health of mother and child.

The Relationship Between Perinatal Mental Health and Stress: a Review of the Microbiome.

PURPOSE OF REVIEW: Our current understanding of the underlying mechanisms and etiologies of perinatal mood and anxiety disorders (PMADs) is not clearly identified. The relationship of stress-induced adaptations (i.e., the hypothalamic-pituitary-adrenal (HPA) axis, the autonomic nervous system (ANS), the immune system) and the microbiota are potential contributors to psychopathology exhibited in women during pregnancy and postpartum and should be investigated. RECENT FINDINGS: The stress response activates the HPA axis and dysregulates the ANS, leading to the inhibition of the parasympathetic system. Sustained high levels of cortisol, reduced heart variability, and modulated immune responses increase the vulnerability to PMAD. Bidirectional communication between the nervous system and the microbiota is an important factor to alter host homeostasis and development of PMAD. Future research in the relationship between the psychoneuroimmune system, the gut microbiota, and PMAD has the potential to be integrated in clinical practice to improve screening, diagnosis, and treatment.

A role for the microbiome in mother-infant interaction and perinatal depression.

Perinatal depression is a significant public health problem, due to its negative impact on maternal well-being and long-term adverse effects for children. Mother-infant interaction and maternal responsiveness and sensitivity are a hypothesized mechanism by which perinatal depression effects child development, and increasing research in the microbiota-gut-brain axis may provide a new avenue of investigation. There is limited efficacy for treatment of perinatal depression for improving the mother-infant relationship and child outcomes. The maternal microbiota may be the basis of child outcomes through foetal programming and sharing of microbes between mother and infant. There is evidence that less diversity of the intestinal microbial community is associated with neuropsychiatric disorders, including depression and anxiety in mothers and offspring. Assessing the maternal and child's microbial communities may be an important missing component in mother-infant attachment-based therapies during treatment of perinatal depression. Probiotics and prebiotics require further research as additions to mother-infant interventions. Further research may enable identification of bacterial genes that indicate specific pathways that could be targeted to improve outcomes for mother and child.

Emerging literature in the Microbiota-Brain Axis and Perinatal Mood and Anxiety Disorders.

Perinatal Mood and Anxiety Disorders (PMAD) are common and can cause significant morbidity and mortality for mother and child. A healthy perinatal period requires significant adaptations; however, systems can become imbalanced resulting in depressive and anxiety symptoms. The interface between the microbiome, the immune system, and the stress system may be a model for understanding mechanisms underlying PMAD. Emerging literature from general populations regarding immune, hormone, and HPA axis changes in relation to the microbiome combined with literature on immune, gonadotropin, and stress systems in the perinatal period provides a background. We systematically investigated literature in the developing field of the microbiome in relation to PMAD. Our inclusion criteria were 1) reporting measure of maternal mood, stress, or anxious or depressed behavior; 2) in the perinatal period, defined as pregnancy through one year postpartum; and 3) reporting measure of maternal microbiome including manipulations of the microbiome through prebiotics, probiotics, or interventions with microbial byproducts. The review identified research studying associations between stress and maternal microbiome; dietary impacts on microbial composition, mood, and stress; and the relationship between the microbiome and the immune system through immunoregulatory mechanisms. Important themes identified include: the importance of studying the maternal microbiome and measures of stress, anxiety, and depression and that multi-hit models will be needed as research strives to determine the effects of multiple mechanisms working in concert.
