ABSTRACT

OBJECTIVE: Racial disparities in diagnosis and treatment are prevalent in child psychiatry, including disparate diagnosis rates of internalizing and externalizing disorders in Black and White children. However, limited research has investigated mechanisms that contribute to these disparities. This study examined child racial implicit associations in psychiatric clinicians and medical students to address this gap. METHOD: Psychiatrists and trainees completed an online survey including 2 race Implicit Association Tests (IATs) pairing child faces to words with either positive or negative valence, and words related to internalizing or externalizing behavioral problems. We further investigated psychiatrists' and trainees' demographic predictors of implicit associations. RESULTS: Data were analyzed from 235 psychiatrists and trainees (112 child and adolescent psychiatrists and fellows) who met inclusion criteria. Psychiatrists and trainees demonstrated greater moderate-to-strong association between Black child faces and "bad" words (44.3%) vs "good" words (6.4%), and between externalizing words (41.7%) and internalizing words (7.2%). Psychiatrists' and trainees' demographic characteristics including being female (ß = -0.12; 95% CI = -0.23 to -0.01; p < .05), Black (ß = -0.36; 95% CI = -0.54 to -0.18; p < .001), or an attending physician (ß = -0.26; 95% CI = -0.45 to -0.06; p = .01) were significant predictors of decreased association between Black child faces and negative valence words. Being female was a significant predictor of decreased association between Black child faces and externalizing words (ß = -0.26; 95% CI = -0.45 to -0.06; p = .01). CONCLUSION: Participating psychiatrists and trainees demonstrated bias toward associating Black rather than White child faces with negative words and externalizing behavioral problems. Future research should examine the following: (1) racial implicit associations in a more generalizable sample, (2) the relationship between race IATs and provider behavior, and (3) interventions to reduce racial inequities in psychiatry, including individual and systemic solutions. DIVERSITY & INCLUSION STATEMENT: We worked to ensure sex and gender balance in the recruitment of human participants. We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants. We worked to ensure that the study questionnaires were prepared in an inclusive way. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented sexual and/or gender groups in science. We actively worked to promote sex and gender balance in our author group. We actively worked to promote inclusion of historically underrepresented racial and/or ethnic groups in science in our author group. One or more of the authors of this paper self-identifies as a member of one or more historically underrepresented racial and/or ethnic groups in science. One or more of the authors of this paper received support from a program designed to increase minority representation in science.

ABSTRACT

Objective: Brief, reliable, and cost-effective methods to assess parenting are critical for advancing parenting research. Design: We adapted the Three Bags task and Parent Child Interaction Rating System (PCIRS) for rating online visits with 219 parent-child dyads (White, n = 104 [47.5%], Black, n = 115 [52.5%]) and combined the video data with survey data collected during pregnancy and when children were aged 1. Results: The PCIRS codes of positive regard, stimulation of child cognitive development, and sensitivity showed high reliability across the three parent-child interaction tasks. A latent positive parenting factor combining ratings across codes and tasks showed good model fit, which was similar regardless of parent self-identified race or ethnicity, age, socioeconomic disadvantage, marital/partnered status, and parity, as well as methodological factors relevant to the online video assessment method (e.g., phone vs. laptop/tablet). In support of construct validity, observed positive parenting was related to parent-reported positive parenting and child socioemotional development. Finally, parent reports of supportive relationships in pregnancy, but not neighborhood safety or pandemic worries, were prospectively related to higher positive parenting observed at age 1. With the exception of older parental age and married/partnered status, no other parent, child, sociodemographic, or methodological variables were related to higher overall video exclusions across tasks. Conclusions: PCIRS may provide a reliable approach to rate positive parenting at age 1, providing future avenues for developing more ecologically valid assessments and implementing interventions through online encounters that may be more acceptable, accessible, or preferred among parents of young children.

ABSTRACT

There is, in the content of the Journal, an embarrassment of riches, and picking a "best" seems to demand a certain qualification: is the "best" the most interesting, most surprising, most educational, most important, most provocative, most enjoyable? How to choose? We are hardly unbiased and can admit to a special affection for the ones that we and the authors worked hardest on, modifying version after version into shape. Acknowledging these biases, here are the 2023 articles that we think deserve your attention or at least a second read.

ABSTRACT

In 2020, we wrote to you of our dedication and vision for JAACAP "to be antiracist at every level."1 Over the last 3 years, we have pursued initiatives "to reshape the Journal to pursue this vision."2,3 In this article, we provide an update on these goals and initiatives (Figure 1). With the launching of our new open access journal, JAACAP Open,4 in late 2022, we now extend these initiatives to both scientific journals in the JAACAP family and aspire to be a leader among mental health journals in our intentional pursuit of antiracist policies and practices.

ABSTRACT

OBJECTIVE: The objective of this study was to assess the impact of household food insecurity (HFI) over time on behavioral and developmental health in early childhood while considering the impact of timing/persistence of HFI and potential differences among racially or ethnically minoritized children. METHODS: Families from the Early Head Start Family and Child Experiences Study (N = 760) were followed longitudinally until age 3 years. Caregiver interview data were collected on HFI, problem behaviors (PBs), delays in development (DD), and sociodemographic information. Analysis of Covariances examined differences between persistent vs transient HFI. Multiple regressions examined the impact of HFI on PB and DD and whether this relation was stronger in racially or ethnically minoritized children. RESULTS: The timing of HFI differentially affected PB, such that those with persistent HFI demonstrated greater PB than those with only early or only late HFI. A different pattern was identified for DD, in which those with late HFI had more DD than those with persistent HFI. Over and above other sociodemographics, including maternal risk factors and an income-to-needs ratio, HFI was associated with greater PB for children of all races and ethnicities. HFI was associated with more DD in non-Latino/a/e/x White families compared with non-Latino/a/e/x Black and Latino/a/e/x families. CONCLUSION: Meaningful differences were found in how the persistence/timing of HFI is differentially associated with PB and DD. In addition, while controlling for socioeconomic risk, a cumulative risk effect was not observed in how HFI affected racially or ethnically minoritized children.

ABSTRACT

INTRODUCTION: Children with callous-unemotional (CU) traits are at high lifetime risk of antisocial behaviour. Low affiliation (ie, social bonding difficulties) and fearlessness (ie, low threat sensitivity) are proposed risk factors for CU traits. Parenting practices (eg, harshness and low warmth) also predict risk for CU traits. However, few studies in early childhood have identified attentional or physiological markers of low affiliation and fearlessness. Moreover, no studies have tested whether parenting practices are underpinned by low affiliation or fearlessness shared by parents, which could further shape parent-child interactions and exacerbate risk for CU traits. Addressing these questions will inform knowledge of how CU traits develop and isolate novel parent and child targets for future specialised treatments for CU traits. METHODS AND ANALYSIS: The Promoting Empathy and Affiliation in Relationships (PEAR) study aims to establish risk factors for CU traits in children aged 3-6 years. The PEAR study will recruit 500 parent-child dyads from two metropolitan areas of the USA. Parents and children will complete questionnaires, computer tasks and observational assessments, alongside collection of eye-tracking and physiological data, when children are aged 3-4 (time 1) and 5-6 (time 2) years. The moderating roles of child sex, race and ethnicity, family and neighbourhood disadvantage, and parental psychopathology will also be assessed. Study aims will be addressed using structural equation modelling, which will allow for flexible characterisation of low affiliation, fearlessness and parenting practices as risk factors for CU traits across multiple domains. ETHICS AND DISSEMINATION: Ethical approval was granted by Boston University (#6158E) and the University of Pennsylvania (#850638). Results will be disseminated through conferences and open-access publications. All study and task materials will be made freely available on lab websites and through the Open Science Framework (OSF).

ABSTRACT

The COVID-19 pandemic has been linked to increased risk for perinatal anxiety and depression among parents, as well as negative consequences for child development. Less is known about how worries arising from the pandemic during pregnancy are related to later child development, nor if resilience factors buffer negative consequences. The current study addresses this question in a prospective longitudinal design. Data was collected from a sub-study (n = 184) of a longitudinal study of pregnant individuals (total n = 1173). During pregnancy (April 17-July 8, 2020) and the early postpartum period (August 11, 2020-March 2, 2021), participants completed online surveys. At 12 months postpartum (June 17, 2021-March 23, 2022), participants completed online surveys and a virtual laboratory visit, which included parent-child interaction tasks. We found more pregnancy-specific pandemic worries were prospectively related to lower levels of child socioemotional development based on parent report (B = - 1.13, SE = .43, p = .007) and observer ratings (B = - 0.13, SE = .07, p = .045), but not to parent-reported general developmental milestones. Parental emotion regulation in the early postpartum period moderated the association between pregnancy-specific pandemic worries and child socioemotional development such that pregnancy-specific pandemic worries did not relate to worse child socioemotional development among parents with high (B = - .02, SE = .10, t = - .14, p = .89) levels of emotion regulation. Findings suggest the negative consequences of parental worry and distress during pregnancy on the early socioemotional development of children in the context of the COVID-19 pandemic. Results highlight that parental emotion regulation may represent a target for intervention to promote parental resilience and support optimized child development.

ABSTRACT

Social support is an influential component of postpartum recovery, adjustment, and bonding, which was disrupted by social distancing recommendations related to the COVID-19 pandemic. This study reports on changes in the availability of social support for postpartum women during the pandemic, investigates how those changes may have contributed to postpartum mental health, and probes how specific types of social support buffered against poor postpartum mental health and maternal-infant bonding impairment. Participants were 833 pregnant patients receiving prenatal care in an urban USA setting and using an electronic patient portal to access self-report surveys at two time points, during pregnancy (April-July 2020) and at ~12 weeks postpartum (August 2020-March 2021). Measures included an assessment of COVID-19 pandemic-related change in social support, sources of social support, ratings of emotional and practical support, and postpartum outcomes including depression, anxiety, and maternal-infant bonding. Overall self-reported social support decreased during the pandemic. Decreased social support was associated with an increased risk of postpartum depression, postpartum anxiety, and impaired parent-infant bonding. Among women reporting low practical support, emotional support appeared to protect against clinically significant depressive symptoms and impaired bonding with the infant. Decreases in social support are associated with a risk for poor postpartum mental health outcomes and impaired maternal-infant bonding. Evaluation and promotion of social support are recommended for healthy adjustment and functioning of postpartum women and families.

ABSTRACT

Current in vitro thrombosis models utilise simplistic 2D surfaces coated with purified components of the subendothelial matrix. The lack of a realistic humanised model has led to greater study of thrombus formation in in vivo tests in animals. Here we aimed to develop 3D hydrogel-based replicas of the medial and adventitial layers of the human artery to produce a surface that can optimally support thrombus formation under physiological flow conditions. These tissue-engineered medial- (TEML) and adventitial-layer (TEAL) hydrogels were developed by culturing human coronary artery smooth muscle cells and human aortic adventitial fibroblasts within collagen hydrogels, both individually and in co-culture. Platelet aggregation upon these hydrogels was studied using a custom-made parallel flow chamber. When cultured in the presence of ascorbic acid, the medial-layer hydrogels were able to produce sufficient neo-collagen to support effective platelet aggregation under arterial flow conditions. Both TEML and TEAL hydrogels possessed measurable tissue factor activity and could trigger coagulation of platelet-poor plasma in a factor VII-dependent manner. Biomimetic hydrogel replicas of the subendothelial layers of the human artery are effective substrates for a humanised in vitro thrombosis model that could reduce animal experimentation by replacing current in vivo models.

ABSTRACT

PURPOSE OF REVIEW: To examine the impacts of gun violence on early childhood development including early childhood mental health, cognitive development, and the assessment and treatment of survivors. RECENT FINDINGS: The literature reflects that gun violence exposure is often associated with significant mental health outcomes including anxiety, post-traumatic stress, and depression in older youth. Historically, studies have focused on adolescents and their exposures to gun violence through proximity to gun violence within their communities, neighborhoods, and schools. However, the impacts of gun violence on young children are less known. Gun violence has significant impacts on mental health outcomes of youth aged 0-18. Few studies focus specifically on how gun violence impacts early childhood development. In light of the increase in youth gun violence over the past three decades with a significant uptick since the onset of the COVID-19 pandemic, continued efforts are needed to better understand how gun violence impacts early childhood development.

ABSTRACT

OBJECTIVE: To examine profiles of distress of mothers of preterm infants in the neonatal intensive care unit (NICU) and relate profiles to maternal and child outcomes at child age 5 years. METHOD: A racially and economically diverse sample of mothers (n = 94; 39% African American, 52% White) of preterm infants (≤30 weeks of gestation) completed validated questionnaires assessing depression, anxiety (state and trait), NICU stress, and life stress at NICU discharge of their infant. Mothers reported on their own and their children's symptomatology at child age 5. A latent profile analysis was conducted to categorize maternal symptomatology. RESULTS: Latent profile analysis yielded 4 distinct maternal profiles: low symptomatology, high NICU stress, high depression and anxiety, and high state anxiety. Social determinants of health factors including age, education, neighborhood deprivation, and infant clinical risk distinguished the profiles. Mothers in the high depression and anxiety profile reported more anxiety and life stress at follow-up and reported their children experienced more anxious/depressed symptoms. CONCLUSION: Existing literature has gaps related to examining multiple dimensions of NICU distress and understanding how patterns of mood/affective symptoms, life stressors, and related social determinants of health factors vary across mothers. In this study, one specific profile of maternal NICU distress demonstrated enduring risks for poorer maternal and child mental health outcomes. This new knowledge underscores sources of disparate health outcomes for mothers of preterm infants and the infants themselves. Universal screening is needed to identify at-risk dyads for poor health outcomes in need of individualized interventions that address both maternal and child well-being. DIVERSITY & INCLUSION STATEMENT: We worked to ensure sex and gender balance in the recruitment of human participants. We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants.

ABSTRACT

Introduction: Racism, a known social determinant of health, affects the mental health and well-being of pregnant and postpartum women and their children. Convincing evidence highlights the urgent need to better identify the mechanisms and the ways in which young children's development and mental health are adversely impacted by their mothers' experiences of racism. With the additional stressor of the COVID-19 pandemic, the criticality of improving knowledge of these domains has never been starker. The proposed project will address these questions and move the field forward to create targeted, culturally informed preventative interventions, thus achieving mental health equity for all children and families. Methods: This prospective research is a cohort study that will longitudinally observe the outcomes of a cohort of mothers and their children recruited during the initial phase of the COVID-19 pandemic. Data will be parent/caregiver questionnaires assessing mental health, racism, support, and resilience at multiple time points with the first beginning at 24 months, clinical interviews with mothers, electronic medical records of mothers, and videotaped dyadic interactions at child age 24 and 48 months. A subset of Black participants will be asked to participate in qualitative interviews at child age 36 months. Results: Analyze will be performed within and across Black and Non-Latino/a/e/x white (NLW) groups, and comparing mothers and fathers/secondary caregivers. Descriptive and multivariate analyzes will be run to better characterize how young children's development and mental health may be adversely impacted by their caregiver's experiences of racism. Discussion: This prospective longitudinal mixed-methods study evaluates the simultaneous effects of the COVID-19 pandemic and racism on mothers and their developing children to characterize cross-racial differences, providing insight into risk and resilience factors in early development and the peripartum period.

ABSTRACT

Importance: The COVID-19 pandemic has been associated with an increase in mental health diagnoses among adolescents, though the extent of the increase, particularly for severe cases requiring hospitalization, has not been well characterized. Large-scale federated informatics approaches provide the ability to efficiently and securely query health care data sets to assess and monitor hospitalization patterns for mental health conditions among adolescents. Objective: To estimate changes in the proportion of hospitalizations associated with mental health conditions among adolescents following onset of the COVID-19 pandemic. Design, Setting, and Participants: This retrospective, multisite cohort study of adolescents 11 to 17 years of age who were hospitalized with at least 1 mental health condition diagnosis between February 1, 2019, and April 30, 2021, used patient-level data from electronic health records of 8 children's hospitals in the US and France. Main Outcomes and Measures: Change in the monthly proportion of mental health condition-associated hospitalizations between the prepandemic (February 1, 2019, to March 31, 2020) and pandemic (April 1, 2020, to April 30, 2021) periods using interrupted time series analysis. Results: There were 9696 adolescents hospitalized with a mental health condition during the prepandemic period (5966 [61.5%] female) and 11 101 during the pandemic period (7603 [68.5%] female). The mean (SD) age in the prepandemic cohort was 14.6 (1.9) years and in the pandemic cohort, 14.7 (1.8) years. The most prevalent diagnoses during the pandemic were anxiety (6066 [57.4%]), depression (5065 [48.0%]), and suicidality or self-injury (4673 [44.2%]). There was an increase in the proportions of monthly hospitalizations during the pandemic for anxiety (0.55%; 95% CI, 0.26%-0.84%), depression (0.50%; 95% CI, 0.19%-0.79%), and suicidality or self-injury (0.38%; 95% CI, 0.08%-0.68%). There was an estimated 0.60% increase (95% CI, 0.31%-0.89%) overall in the monthly proportion of mental health-associated hospitalizations following onset of the pandemic compared with the prepandemic period. Conclusions and Relevance: In this cohort study, onset of the COVID-19 pandemic was associated with increased hospitalizations with mental health diagnoses among adolescents. These findings support the need for greater resources within children's hospitals to care for adolescents with mental health conditions during the pandemic and beyond.

ABSTRACT

In 2020, we wrote to you of our dedication and vision for this Journal "to be antiracist at every level," outlining the following 6 initiatives "to reshape the Journal to pursue this vision:" (1) Issuing a Call for Papers on racism and its impacts on child development and children's mental health; (2) updating our Guide for Authors to emphasize that we will evaluate articles submitted to the Journal on whether their study designs are inclusive and their discussions consider and address human diversity and structural determinants of health in the context of their research questions and hypotheses; (3) assembling a special collection of Journal articles on bias, bigotry, discrimination, racism, and mental health inequities; (4) accelerating our efforts to make our Editorial Board inclusive and representative of our community of scientists and practitioners as well as the communities we serve; (5) engaging in continuing education and dialogue as an Editorial Board that will include antiracism training and praxis; and (6) critically examining "our editorial and peer review process to ensure it is antiracist."1 In this Editors' Note, we write to update you on our progress, including a new initiative we started in the past year: (7) a new option for authors to add a statement to their manuscripts regarding the inclusion and diversity initiatives and practices they employed in pursuing their work. With the launch this year of JAACAP Open, the Academy's new open access publication and the newest member of the JAACAP family of journals, we have expanded opportunities to pursue these efforts, and look forward to sharing more about JAACAP Open in future updates.

ABSTRACT

Cardiovascular diseases are still among the leading causes of mortality and morbidity worldwide. The build-up of fatty plaques in the arteries, leading to atherosclerosis, is the most common cause of cardiovascular diseases. The central player in atherosclerotic plaque formation is the foam cell. Foam cells are formed when monocytes infiltrate from the blood stream into the sub-endothelial space, differentiating into macrophages. With the subsequent uptake and storage of lipoprotein, especially low-density lipoprotein (LDL), they change their phenotype to lipid laden cells. Lowering circulating LDL levels, or initiating cholesterol efflux/reverse cholesterol transport in foam cells, is one of the current clinical therapies. Prescription of the pleiotropic drugs, statins, is the most successful therapy for the treatment and prevention of atherosclerosis. In this study, we used a foam cell model from the macrophage cell line, RAW 246.7, and applied the label-free Fourier Transform Infrared Spectroscopy (FTIR) method, i.e. synchrotron-based microFTIR spectroscopy, to study the lipid efflux process initiated by statins in a dose and time dependent manner. We used glass coverslips as substrates for IR analysis. The optical images (visible and fluorescent light) clearly identify the localization and lipid distribution within the foam cells, and the associated changes before and after culturing them with atorvastatin at concentrations of 0.6, 6 and 60 µg mL-1, for a culture duration between 24 to 72 hours. MicroFTIR spectroscopic spectra uniquely displayed the reduction of lipid content, with higher lipid efflux observed at higher doses of, and longer incubation time with, atorvastatin. Principal Component Analysis (PCA) and t-distributed Stochastic Neighbor Embedding (t-SNE) analysis demonstrated defined cluster separation at both lipid (3000-2800 cm-1) and fingerprint (1800-1350 cm-1) regions, with more profound discrimination for the atorvastatin dose treatment than time treatment. The data indicate that combining synchrotron-based microFTIR spectroscopy and using glass substrates for foam cells can offer an alternative tool in atherosclerosis investigation at a molecular level, and through cell morphology.

ABSTRACT

Childbirth trauma is common and increases risk for postpartum depression (PPD). However, we lack brief measures to reliably identify individuals who experience childbirth trauma and who may be at greater prospective risk for PPD. To address this gap, we used data from a racially diverse prospective cohort (n=1082). We collected survey data during pregnancy and at 12 weeks postpartum, as well as clinician-reported data from medical records. A new three-item measure of patient-reported childbirth trauma was a robust and independent risk factor for PPD, above and beyond other known risk factors for PPD, including prenatal anxiety and depression. Cesarean birth, greater blood loss, and preterm birth were each associated with greater patient-reported childbirth trauma. Finally, there were prospective indirect pathways whereby cesarean birth and higher blood loss were related to higher patient-reported childbirth trauma, in turn predicting greater risk for PPD. Early universal postpartum screening for childbirth trauma, targeted attention to individuals with childbirth complications, and continued screening for depression and anxiety can identify individuals at risk for PPD. Such efforts can inform targeted interventions to improve maternal mental health, which plays a vital role in infant development.

ABSTRACT

Importance: The intersection of endemic structural racism and the global health crisis secondary to the COVID-19 pandemic represents a syndemic, defined as the aggregation of 2 or more endemic and epidemic conditions leading to adverse repercussions for health. Long-standing inequities have placed Black individuals at disproportionate risk for negative postpartum mental health outcomes. Studies are urgently needed to understand how the COVID-19 pandemic has added to this risk (eg, syndemic associations). Objective: To examine the association between the syndemic and the postpartum mental health of Black birthing individuals. Design, Setting, and Participants: A longitudinal cohort of Black birthing individuals were followed up from pregnancy (April 17 to July 8, 2020) through the early postpartum period (August 11, 2020, to March 2, 2021) from urban university medical center prenatal clinics. Pregnant Black participants were recruited via email and completed 2 online surveys. Main Outcomes and Measures: Composite variables capturing negative experiences of the COVID-19 pandemic and racism (structural racism [general], structural racism [neighborhood], and interpersonal racism) were created. Logistic regressions examined main and interactive associations between these variables and postpartum depression (Edinburgh Postnatal Depression Scale) and anxiety (Generalized Anxiety Disorder 7-item scale). Results: The mean (SD) age of 151 Black participants was 30.18 (5.65) years. The association between higher negative COVID-19 pandemic experiences and postpartum depression may be influenced by experiences of interpersonal racism and general systemic racism. Negative COVID-19 pandemic experiences were associated with greater likelihood of screening positive for depression only at higher levels of systemic racism (odds ratio, 2.52; 95% CI, 1.38-4.60) and interpersonal racism (odds ratio, 1.90; 95% CI, 1.04-3.48) but not at lower levels of systemic or interpersonal racism. Similarly, negative COVID-19 experiences were associated with anxiety only at higher levels of interpersonal racism (odds ratio, 1.85; 95% CI, 0.86-4.01) but not at lower levels of interpersonal racism. Overall, 44 (29%) met screening criteria for postpartum depression and 20 (13%) for postpartum anxiety. Conclusions and Relevance: In this longitudinal cohort study of Black birthing individuals, the experience of the syndemic was associated with negative postpartum mental health. Associations between interpersonal racism, structural racism, and negative COVID-19 pandemic experiences were associated with greater risk for postpartum depression and anxiety. Research is needed to address how systemic racism perturbs biobehavioral pathways to magnify associations between acute stressors and mental health. Such research can inform the creation of effective, culturally informed preventive interventions to improve the postpartum mental health of Black individuals.
