A National Institutes of Health Approach for Advancing Research to Improve Youth Mental Health and Reduce Disparities.

Even before the COVID-19 pandemic, mental health challenges were the leading cause of disability and poor health outcomes in youth. Challenges are even greater for youth from racially and ethnically minoritized groups in the United States. Racially and ethnically minoritized youth are more vulnerable to mental health problems than White adolescents, yet are less likely to use mental health services. In late 2021, the National Institutes of Health (NIH) sponsored a virtual conference to examine the state of the science around youth mental health disparities (YMHD), focusing on youth from racially and ethnically minoritized populations and the intersection of race and ethnicity with other drivers of mental health disparities. Key findings and feedback gleaned from the conference have informed strategic planning processes related to YMHD, which has included the development of a strategic framework and funding opportunities, designed to reduce YMHD. This commentary briefly describes the collaborative approach used to develop this framework and other strategies implemented across the NIH to address YMHD and serves as an urgent call to action.

The Role of the National Institute of Mental Health in Promoting Diversity in the Psychiatric Research Workforce.

The mission of the National Institute of Mental Health (NIMH) is to transform the understanding and treatment of mental illnesses through basic and clinical research, paving the way for prevention, recovery, and cure. This mission can only be realized if full participation in the research enterprise is open to all. Nevertheless, systemic racism and other barriers remain significant obstacles to achieving a diverse workforce. To address these barriers, NIMH must ensure a just and equitable funding process, support diversity-focused training opportunities, and encourage research into mental health disparities and other areas of interest to a diverse array of scientists.

Tbx5 maintains atrial identity in post-natal cardiomyocytes by regulating an atrial-specific enhancer network.

Understanding how the atrial and ventricular heart chambers maintain distinct identities is a prerequisite for treating chamber-specific diseases. Here, we selectively knocked out (KO) the transcription factor Tbx5 in the atrial working myocardium to evaluate its requirement for atrial identity. Atrial Tbx5 inactivation downregulated atrial cardiomyocyte (aCM) selective gene expression. Using concurrent single nucleus transcriptome and open chromatin profiling, genomic accessibility differences were identified between control and Tbx5 KO aCMs, revealing that 69% of the control-enriched ATAC regions were bound by TBX5. Genes associated with these regions were downregulated in KO aCMs, suggesting they function as TBX5-dependent enhancers. Comparing enhancer chromatin looping using H3K27ac HiChIP identified 510 chromatin loops sensitive to TBX5 dosage, and 74.8% of control-enriched loops contained anchors in control-enriched ATAC regions. Together, these data demonstrate TBX5 maintains the atrial gene expression program by binding to and preserving the tissue-specific chromatin architecture of atrial enhancers.

Acute sleep deprivation disrupts emotion, cognition, inflammation, and cortisol in young healthy adults.

Chronic sleep deprivation has been demonstrated to diminish cognitive performance, alter mood states, and concomitantly dysregulate inflammation and stress hormones. At present, however, there is little understanding of how an acute sleep deprivation may collectively affect these factors and alter functioning. The present study aimed to determine the extent to which 24-h of sleep deprivation influences inflammatory cytokines, stress hormones, cognitive processing across domains, and emotion states. To that end, 23 participants (mean age = 20.78 years, SD = 2.87) filled out clinical health questionnaires measured by the Pittsburgh Sleep Quality Index, Morningness Eveningness Questionnaire, and Center for Epidemiological Studies Depression Scale. Actigraph was worn for seven days across testing to record sleep duration. At each session participants underwent a series of measures, including saliva and blood samples for quantification of leptin, ghrelin, IL-1ß, IL-6, CRP, and cortisol levels, they completed a cognitive battery using an iPad, and an emotion battery. We found that an acute sleep deprivation, limited to a 24 h period, increases negative emotion states such as anxiety, fatigue, confusion, and depression. In conjunction, sleep deprivation results in increased inflammation and decreased cortisol levels in the morning, that are accompanied by deficits in vigilance and impulsivity. Combined, these results suggest that individuals who undergo 24 h sleep deprivation will induce systemic alterations to inflammation and endocrine functioning, while concomitantly increasing negative emotions.

Positive affective priming decreases the middle late positive potential response to negative images.

INTRODUCTION: This study aims to expand on previous literature showing that incidental emotion state priming in a specific domain leads to a higher probability that the primed emotion domain will be activated during a subsequent task. METHODS: To that end, we investigated the influence of happy, fearful, and neutral incidental emotion state priming on subsequent responses to emotionally negative and neutral pictures, measured by the event-related potential (ERP) late positive potential (LPP). New to our study, we examined the influence of affective priming on the LPP response (analyzed separately at early and middle latency ranges) to emotional pictures in both the foveal and extrafoveal presentation locations. RESULTS: Following both fearful and neutral incidental state priming, both the early and middle LPP latency ranges overwhelmingly differentiated between negative and neutral pictures. Following happy incidental state priming, however, the LPP response failed to differentiate between negative and neutral pictures by the middle LPP latency range (800-1,000 ms). These results suggest that incidental happy states can have a protective effect when viewing aversive stimuli. Additionally, the LPP showed greater sensitivity to negative stimuli when presented extrafoveally compared to foveally. CONCLUSIONS: Overall, our findings suggest that incidental affective state and stimulus location influence emotional processing differentially for emotionally negative and emotionally neutral stimuli.

Catechol-O-methyltransferase Val158Met polymorphism associates with affect and cortisol levels in women.

Introduction: We tested the extent to which the catechol-O-methyltransferase (COMT) Val158Met polymorphism is associated with affective state and evening cortisol levels. We limited our study to women as previous research suggests that the link between COMT genotype and psychological health is entangled by sex differences. Materials and Methods: The participants were assessed on measures of anxiety, mood disturbance, depressive symptomatology, and perceived stress. We also evaluated participants on a quality of life measures that included two emotion domains and two physical domains (physical health and environment). Results: We found that under normal (nonstress) conditions, the COMT A allele (Met carriers, higher dopamine) associates with healthier affect and lower afternoon cortisol levels in women. These effects were limited to affective measures and not to physical or environmental quality of life. Conclusions: These findings help to shed light on the complex nature of COMT and emotion, and suggest that both sex and task condition (stress vs. nonstress) should be considered when examining the relationship between COMT genotype and emotion.

The impact of nurse case management home visitation on birth outcomes in African-American women.

UNLABELLED: The views expressed in this article are those of the authors and do not necessarily reflect the official policy or position of the Uniformed Services University of the Health Sciences, Department of the Navy, Department of Defense or the U. S. government. Dr. Wells is a military service member (employee of the U.S. government). This work was prepared as a part of her official duties. Title 17, USC Section 101 defines a U.S. government work as a work prepared by a military service member or employee of the U.S. government as part of the person's official duties. Despite substantial reductions in U.S. infant mortality rates, racial disparities persist, with black Americans experiencing 2.4 times the rate of their white counterparts. Low birthweight and preterm delivery contribute to this disparity. METHODS: To examine the association between antepartum nurse case management home visitation and the occurrence of low birthweight and preterm deliveries in African-American women in Montgomery County, MD, a retrospective cohort study was conducted using existing data from 109 mothers who were enrolled in the Black Babies Start More Infants Living Equally Healthy (SMILE) program. Logistic regression analysis was used. RESULTS: Women who received antepartum home visits were 0.37 (CI 0.15-0.94) times less likely to experience preterm delivery than women who did not receive antepartum home visits. The effect of antepartum home visits on preterm delivery was independent of level of prenatal care, negative life events and number of prior live births. There was no significant association between antepartum home visits and low birthweight. CONCLUSION: Antepartum home visits appeared to be protective against preterm delivery and could contribute to reducing racial disparities in infant mortality. Further study is needed to understand and replicate specific program components that may contribute to improved birth outcomes in African-American women.

Cultural competency training for third-year clerkship students: effects of an interactive workshop on student attitudes.

UNLABELLED: With an increasing awareness of health disparities, medical schools are challenged to develop training in cultural competency for their students. We developed and evaluated the effectiveness of an interactive workshop designed to improve third-year students' attitudes, beliefs and cross-cultural communication skills. METHODS: At the start of a six-week required family medicine clerkship, 196 medical students participated in small group (20-24 students) workshops. Didactics included facts about health disparities and a model of cultural competency. During a skill-building component, students were exposed to live vignettes portraying ineffective and effective cross-cultural doctor-patient interactions. Impact on students' attitudes, perceived bias and knowledge of techniques was assessed by comparing pre- and postworkshop scores. RESULTS: Participants increased their cultural awareness on most items of a cultural awareness scale. Fifty-five-, 71- and 66% of the sample agreed or strongly agreed the program was valuable, appropriate and effective, respectively. Conversely, only 17-, 6- and 9% of the sample disagreed or strongly disagreed, respectively. CONCLUSIONS: A workshop for third-year students led to an increase in cultural awareness and was considered appropriate and valuable. Further study, including longitudinal training and evaluation, is needed regarding effective methods to increase cultural competence in clinical practice.

Obstetrician-gynecologists' decision making about the diagnosis of major depressive disorder and premenstrual dysphoric disorder.

Major depressive disorder (MDD) is underdiagnosed and undertreated in ambulatory care settings including gynecologic practices. Far less is known about the diagnosis of Premenstrual Dysphoric Disorder (PMDD). Three hundred and thirty-five gynecologists responded to mailed questionnaires that used descriptive scenarios as analogues to clinical cases. Questionnaire recipients were randomly selected to receive either a MDD or PMDD version of the questionnaire. Respondents were less accurate when diagnosing MDD cases (48% accuracy; p = 0.526), than PMDD cases (80% accuracy; p < 0.001), but were significantly more confident about their probability ratings of MDD cases, t = 2.57, p < 0.02. Qualitative analysis suggested that less accurate MDD respondents did not prioritize case data according to DSM-IV criteria, whereas almost all PMDD respondents made use of valid reasoning strategies. Respondents did not take base rates into account when deciding about the probability of either affective disorder. Results imply that gynecologists employ cognitive strategies that result in accurate diagnostic judgments about PMDD, but overconfidence, lack of attention to DSM-IV criteria and base rate neglect could hinder clinical decisions about MDD, and may contribute to underdiagnosis of depression.
