ABSTRACT

BACKGROUND: Accumulating evidence indicates that higher prenatal maternal inflammation is associated with increased depression risk in adolescent and adult-aged offspring. Prenatal maternal inflammation (PNMI) may increase the likelihood for offspring to have lower cognitive performance, which, in turn, may heighten risk for depression onset. Therefore, this study explored the potential mediating role of childhood cognitive performance in the relationship between PNMI and adolescent depressive symptoms in offspring. METHODS: Participants included 696 mother-offspring dyads from the Child Health and Development Studies (CHDS) cohort. Biomarkers of maternal inflammation [interleukin (IL)-6, IL-8, IL-1 receptor antagonist (IL-1RA) and soluble TNF receptor-II (sTNF-RII)] were assayed from first (T1) and second trimester (T2) sera. Childhood (ages 9-11) cognitive performance was assessed via standardized Peabody Picture Vocabulary Test (PPVT), a measure of receptive vocabulary correlated with general intelligence. Adolescent (ages 15-17) depressive symptoms were assessed via self-report. RESULTS: There were no significant associations between T1 biomarkers and childhood PPVT or adolescent depressive symptoms. Higher T2 IL1-RA was directly associated with lower childhood PPVT (b = -0.21, SE = 0.08, t = -2.55, p = 0.01), but not with adolescent depressive symptoms. T2 IL-6 was not directly associated with childhood PPVT, but higher T2 IL-6 was directly associated at borderline significance with greater depressive symptoms in adolescence (b = 0.05, SE = 0.03, t = 1.96, p = 0.05). Lower childhood PPVT predicted significantly higher adolescent depressive symptoms (b = -0.07, SE = 0.02, t = -2.99, p < 0.01). There was a significant indirect effect of T2 IL-1RA on adolescent depressive symptoms via childhood PPVT (b = 0.03, 95 % CI = 0.002-0.03) indicating a partially mediated effect. No significant associations were found with T2 sTNF-RII nor IL-8. CONCLUSIONS: Lower childhood cognitive performance, such as that indicated by a lower PPVT score, represents a potential mechanism through which prenatal maternal inflammation contributes to adolescent depression risk in offspring.

ABSTRACT

Prenatal maternal stress (PNMS) is linked to physical sequelae in offspring, including childhood asthma. This study sought to examine the roles of objective and subjective PNMS in the development of asthma at offspring ages 5 and 15. The sample included 815 mother-child dyads from the Mater Misericordiae Mothers' Hospital-University of Queensland Study of Pregnancy. PNMS was measured via retrospective self-report during pregnancy and 3-5 days after birth. Postnatal maternal stress was measured at offspring age 5. Objective PNMS was associated with elevated asthma risk at age 5 (OR 1.21, 95% CI 1.00, 1.45, p = 0.05), albeit not above concurrent postnatal stress. Sex moderated the association between PNMS and asthma at age 15, controlling for postnatal stress. Sex stratified analyses revealed a positive association between objective PNMS and age 15 asthma in females, but not males. Results provide evidence that PNMS may impact asthma outcomes in adolescence.

ABSTRACT

Risk for psychosis begins to accumulate as early as the fetal period through exposure to obstetric complications like fetal hypoxia, maternal stress, and prenatal infection. Stressors in the postnatal period, such as childhood trauma, peer victimization, and neighborhood-level adversity, further increase susceptibility for psychosis. Cognitive difficulties are among the first symptoms to emerge in individuals who go on to develop a psychotic disorder. We review the relationship between pre-, perinatal, and early childhood adversities and cognitive outcomes in individuals with psychosis. Current evidence shows that the aforementioned environmental risk factors may be linked to lower overall intelligence and executive dysfunction, beginning in the premorbid period and persisting into adulthood in individuals with psychosis. It is likely that early life stress contributes to cognitive difficulties in psychosis through dysregulation of the body's response to stress, causing changes such as increased cortisol levels and chronic immune activation, which can negatively impact neurodevelopment. Intersectional aspects of identity (e.g., sex/gender, race/ethnicity), as well as gene-environment interactions, likely inform the developmental cascade to cognitive difficulties throughout the course of psychotic disorders and are reviewed below. Prospective studies of birth cohorts will serve to further clarify the relationship between early-life environmental risk factors and cognitive outcomes in the developmental course of psychotic disorders. Specific methodological recommendations are provided for future research.

ABSTRACT

The COVID-19 pandemic increased many known risk factors for mental health problems. In the context of overwhelmed health systems and resource and staffing shortages, the mental health needs of frontline health care workers (HCWs) gained attention as a major public health concern and a threat to high-quality care delivery. In response, mental health promotion initiatives were quickly developed to meet the demands of the public health crisis. Two years later, the context for psychotherapy has changed, especially as it pertains to the health care workforce. Particularly salient experiences-grief, burnout, moral injury, compassion fatigue, and racial trauma-have become routinely discussed as part of everyday clinical practice. Service programs have become more responsive to the needs, schedules, and identities of HCWs. In addition, mental health and other HCWs have contributed to advocacy and volunteer initiatives promoting health equity, culturally responsive care, and access to care across a range of settings. In this article, the authors review the benefits of these activities to individuals, organizations, and communities and summarize example programs. Many of these initiatives began in response to the acute public health crisis; however, engaging in these ways and spaces holds promise for increasing connection and prioritizing equity and structural change over the long term.

ABSTRACT

OBJECTIVE: Black children are disproportionately affected by atopic diseases (i.e., atopic dermatitis, allergic rhinitis, asthma, and food allergies), with health disparities present in early life. Studies in White samples suggest that maternal stress confers risk for offspring atopy, yet little is known about these relationships in Black populations. This study seeks to (a) examine the relationship between self-reported and physiological indicators of maternal stress and offspring atopy and (b) explore warm and responsive caregiving as a potential protective factor in Black Americans. METHODS: A sample of 179 Black mother-child dyads of varying socioeconomic status participated in a prospective longitudinal study. Mothers completed self-reports of childhood trauma, prenatal stress, postnatal stress, and physician diagnosis of offspring atopy; provided blood samples to assess physiological responses to chronic stress exposure; and participated in a behavioral task with their infant. RESULTS: Maternal self-reports of childhood trauma, prenatal stress, and postnatal stress were not associated with offspring diagnosis of atopy by 2-3 years of age. Mothers who produced a smaller inflammatory response during pregnancy were more likely to have an offspring with atopy by 2-3 years of age. Warm and responsive parenting demonstrated a protective effect; the positive association between maternal stress and offspring atopy was less apparent in cases of mother-child interactions characterized by high levels warm and responsive parenting. CONCLUSION: Failure to replicate previous findings suggests that the maternal stress-offspring atopy relationship is complex. Future studies must examine the unique stressors in Black Americans, as well as caregiving as a potential protective factor.

ABSTRACT

AIM: Childhood Adversity (CA) is strongly linked to psychotic-like symptoms across the clinical spectrum, though the mechanisms underlying these associations remain poorly understood. Negative cognitive schemas are associated with both CA exposure and psychotic symptoms, highlighting the possibility that cognitive schemas may be a key risk pathway. The purpose of this study was to determine whether negative cognitive schemas mediate the association between CA and specific attenuated psychotic symptoms in a large sample of clinical-high risk youth. Given the variability in experiences that encompass CA (eg, abuse, neglect and poverty) and attenuated psychotic symptoms (eg, suspiciousness and perceptual abnormalities), we also tested whether these associations differ by CA type (threat vs deprivation) and attenuated positive psychotic symptom domain. METHODS: Data were collected from 531 clinical-high risk youth between 12 and 35 years of age (mean = 18.80, SD = 4.21) who completed a clinical assessment that included the Structured Interview of Prodromal Syndromes (SIPS), Childhood Trauma and Abuse scale and questionnaires on cognitive schemas and depressive symptoms. RESULTS: No direct effects of threat or deprivation exposure on any of the psychotic symptom domains were found. However, there was a unique indirect effect of threat, but not deprivation, on delusional thinking and suspiciousness through negative cognitive schemas about others. CONCLUSION: Cognitive vulnerability in the form of negative schemas about others may be one mechanism linking childhood threat experiences and attenuated psychotic symptoms. The results underscore the importance of targeting negative schemas in interventions to mitigate psychosis risk.
