ABSTRACT

Following a traumatic event such as intimate partner violence (IPV), survivors often experience stress related to the violence. These high levels of stress related to IPV can be associated with the daily activities of survivors and their relationships with their children, such as maternal-child bonding. The purpose of the current study is to explore the relationship between daily activities, daily stress levels, parenting self-efficacy and behaviors, and maternal-child bonding among survivors living in an IPV shelter using an ecological momentary assessment (EMA) methodology. Twenty-five mothers living in an IPV shelter in two states in the Southern United States completed a baseline survey and completed electronic daily diaries for 14 days. Higher daily stress was associated with the number of times the mothers met with the case manager. Higher daily stress was also related to lower parenting self-efficacy. The number of case management appointments and legal appointments were positively correlated with a higher bonding score. More social support was associated with more positive parenting. IPV and post-traumatic stress disorder symptoms were not significantly associated with maternal-child bonding, parenting behaviors, or parenting self-efficacy. Findings suggest that screening for maternal support may be particularly important for positive bonding and positive parenting. Findings also lend preliminary insight into practical places where service providers could act to protect the bonding process or mitigate risks to impede it. Future research should include objective data about the mother's emotions and her interactive behavior with her child. There is also a need to consider how federal programs fund and incentivize service providers to focus on mother-child dyads and how they can tailor services that promote bonding.

ABSTRACT

Emotional abuse up to age 18 is associated with depressive symptoms in adulthood, yet few studies have examined these links in Black females. Despite research documenting the moderating role of sleep duration on early adversity and mental health, no studies have examined whether sleep duration during adolescence moderates the relations between emotional abuse up to age 18 and depressive symptoms in adulthood. We examined these relations in 690 Black females from the National Longitudinal Study of Adolescent Health (Add Health)-Public Use. Individuals reported the frequency of emotional abuse up to age 18, hours of sleep during adolescence, and depressive symptoms using the 10-item version of the Center for Epidemiological Studies Depression Scale. Only 55% of adolescents reported sleeping the recommended 8-10 hr per night. Frequent emotional abuse before age 18 years was associated with more adult depressive symptoms for those with shorter, but not longer, sleep duration. Greater attention should be placed on facilitating and promoting sleep health for Black females. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

ABSTRACT

Biological changes contribute to preferences for later bed and wake times during adolescence, yet the social constraints of school start times necessitate early wake times. This often results in social jetlag (i.e. misalignment between preferred sleep timing on weekends and school days). We examined whether social jetlag predicts adolescent internalizing and externalizing behavior over time and/or whether associations differ based on sex. We used data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development Study (n = 767) to test whether social jetlag at 6th grade (ages 12-13 years) predicted internalizing and externalizing behavior at age 15 years and whether child sex moderated associations. Controlling for internalizing and externalizing behavior at 6th grade (ages 12-13 years), results were that social jetlag at 6th grade (ages 12-13 years) predicted more internalizing and externalizing behaviors at age 15 for females, but not males. These findings show that social jetlag during early adolescence confers risk for internalizing and externalizing behavior in females at mid-adolescence. Greater attention should be placed on identifying and addressing social jetlag in adolescent females.

ABSTRACT

OBJECTIVES: To test the association between racial discrimination and cardiovascular-related conditions and whether PTSD mediates this relationship in a nationally representative sample of non-Hispanic Blacks. METHODS: We used data from the 2013 National Epidemiologic Survey on Alcohol and Related Conditions to conduct logistic regression analyses to examine the association between racial discrimination, PTSD, and cardiovascular-related conditions. We also performed mediation analyses to assess whether the association between racial discrimination and cardiovascular conditions was partly explained by PTSD. RESULTS: Racial discrimination was positively associated with both PTSD and cardiovascular-related conditions. Additionally, PTSD was positively associated with cardiovascular conditions. Results from the fully adjusted mediation models suggest that PTSD significantly mediated the association between racial discrimination and cardiovascular conditions. CONCLUSIONS: Our results demonstrate an association between racial discrimination and cardiovascular-related conditions that is significantly mediated by PTSD. To improve cardiovascular functioning among non-Hispanic Blacks, health care professionals in conjunction with Black communities must adopt culturally competent screening for and treatment for PTSD. To address racial differences in cardiovascular conditions, public health efforts must address institutional policies that negatively alter health opportunities among the Black population.

ABSTRACT

As the United States faces the repercussions of the current opioid epidemic, it is important for social workers to be able to identify risks for poor birth outcomes in infants with neonatal abstinence syndrome (NAS). Although some studies have identified single risk factors, no studies have tested associations between total amount of risk (that is, cumulative risk) and birth outcomes in infants with NAS. Authors examined 318 mothers who used opioids during pregnancy and their infants' birthweight, length, head circumference, and Apgar scores (which measure overall infant health after birth). All infants were admitted to a neonatal intensive care unit in Appalachia and were diagnosed with NAS. Authors found that high cumulative risk during pregnancy was associated with lower birthweight and Apgar scores one and five minutes after birth as well as shorter length and smaller head circumference at birth. Social workers are encouraged to assess for the quantity of prenatal adversity experienced by the mothers they serve and to consider multicomponent, comprehensive community-based interventions to reduce cumulative risk.

ABSTRACT

Racial disparities in sleep have been reported with Black adolescents showing the least amount of sleep relative to other youth. Yet, few within-group studies have examined factors that protect Black adolescents from sleep problems. To address this gap, we tested whether parent ethnic-racial socialization (i.e., instilling a sense of cultural and racial pride) at fourth grade moderated the associations between bedtime sleep problems at third and sixth grade. Using data from a sample of Black parents and children who participated in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n = 173), we found that for children with low, but not high, parent ethnic-racial socialization at fourth grade bedtime problems increased from third and sixth grade. We discuss these findings within the existing parent ethnic-racial socialization and sleep literatures and how they further our understanding of the protective effects of parent ethnic-racial socialization.

ABSTRACT

Data from the National Institute of Child Health and Human Development Study of Early Child Care were used to test whether maternal sensitivity and stimulation at 15 and 54 months predicted child attention, impulsivity, and delay of gratification at 54 months, and whether toddler attention and temperamental difficultness moderated associations. Maternal sensitivity at 54 months was positively associated with children's delay of gratification and negatively associated with inattention and impulsivity at 54 months. Maternal stimulation at 15 months was negatively associated with inattention at 54 months for toddlers with higher levels of attention focusing and temperamental difficultness. The importance of attending to individual differences is discussed.

ABSTRACT

BACKGROUND: In most studies, religiosity and spirituality (R/S) are positively associated with altruism, whereas depression is negatively associated. However, the cross-sectional designs of these studies limit their epidemiological value. We examine the association of R/S and major depressive disorder (MDD) with altruism in a five year longitudinal study nested in a larger prospective study. METHODS: Depressed and non-depressed individuals and their first- and second-generation offspring were assessed over several decades. At Year30 after baseline, R/S was measured using participants' self-report; MDD, by clinical interview. At Year35, participants completed a measure of altruism. Adjusted odds ratios (AOR) were calculated using multivariate logistic regression; statistical significance, set at p<.05. two-tailed. RESULTS: In the overall sample, both R/S and MDD were significantly associated with altruism, AOR 2.52 (95% CI 1.15-5.49) and AOR 2.43 (95% CI 1.05-5.64), respectively; in the High Risk group alone, the corresponding AORs were 4.69 (95% CI 1.39-15.84) and 4.74 (95% CI 1.92-11.72). Among highly R/S people in the High Risk group, the AOR for MDD with altruism was 22.55 (95% CI 1.23-414.60) p<.04; among the remainder, it was 3.12 (95% CI 0.63-15.30), a substantial but non-significant difference. LIMITATIONS: Altruism is based on self-report, not observation, hence, vulnerable to bias. CONCLUSIONS: MDD's positive association with elevated altruism concurs with studies of posttraumatic growth in finding developmental growth from adversity. The conditions that foster MDD's positive association with altruism and the contribution of R/S to this process requires further study.

ABSTRACT

Theory underscores the importance of parenting in sleep development, but few studies have examined whether links vary by temperament. To address this gap, we tested whether potential links between early maternal sensitivity and early adolescent sleep problems varied by child negative emotionality and delay of gratification. Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 820), we found that high maternal sensitivity predicted fewer bedtime problems and longer sleep duration at 6th grade for toddlers with high negative emotionality, whereas low maternal sensitivity predicted the reverse. No differences were observed for low negative emotionality. Moreover, delay of gratification predicted fewer bedtime problems at 6th grade, but did not moderate associations between maternal sensitivity, negative emotionality, and sleep. Findings demonstrate that high, but not low, negative emotionality renders toddlers differentially susceptible and receptive to maternal sensitivity in relation to sleep.

ABSTRACT

Sleep problems are associated with problematic adjustment in toddlers, but less is known regarding the direction of association between specific sleep problems and adjustment. To address this gap, we used data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1001) to examine reciprocal associations between sleep problems and behavior problems from 24- to 36-months. Results from cross-lagged path models suggested specificity of associations between type of sleep problem and behavior problem. Specifically, there were reciprocal associations between trouble getting to sleep and internalizing problems, and unidirectional links between externalizing problems and bedtime resistance from 24- to 36-months. Internalizing and externalizing problems at 24 months, however, predicted increases in bedtime resistance from 24- to 36-months for boys, but not girls. Findings highlight specific relations between sleep problems and internalizing and externalizing problems during toddlerhood, and the importance of examining sex differences.

ABSTRACT

Human pluripotent stem cells (hPSCs) require precise control of post-transcriptional RNA networks to maintain proliferation and survival. Using enhanced UV crosslinking and immunoprecipitation (eCLIP), we identify RNA targets of the IMP/IGF2BP family of RNA-binding proteins in hPSCs. At the broad region and binding site levels, IMP1 and IMP2 show reproducible binding to a large and overlapping set of 3' UTR-enriched targets. RNA Bind-N-seq applied to recombinant full-length IMP1 and IMP2 reveals CA-rich motifs that are enriched in eCLIP-defined binding sites. We observe that IMP1 loss in hPSCs recapitulates IMP1 phenotypes, including a reduction in cell adhesion and increase in cell death. For cell adhesion, we find IMP1 maintains levels of integrin mRNA specifically regulating RNA stability of ITGB5 in hPSCs. Additionally, we show that IMP1 can be linked to hPSC survival via direct target BCL2. Thus, transcriptome-wide binding profiles identify hPSC targets modulating well-characterized IMP1 roles.

ABSTRACT

BACKGROUND: Little is known about the specific factors related to whether or not Latino adolescents with suicide ideation (SI) will seek services. Utilizing Andersen's Behavior Model of Health Services Use (2008) the goal of this study is to identify the factors related to utilization of mental health services by Latino adolescents with SI to inform and improve suicide prevention efforts. METHOD: Data from Wave 1 of the National Longitudinal Study of Adolescent Health was examined. Predispositional (gender, age), enabling/disabling (income, lack of insurance, difficulty obtaining medical care), and need (depressed mood, suicide attempt, perceived health, impulsivity, mood fluctuations, difficulties with attention, etc.) variables were examined via logistic regression as potential correlates of mental health service utilization. RESULTS: Twenty-eight percent of the Latino adolescents with suicidal ideation (SI) in our sample received mental health services. Need factors such as daily mood fluctuations within the past 12 months (OR=4.78) and frequent difficulty focusing attention within the past week (OR=4.96), but not impulsivity, were associated with an increased likelihood of receiving mental health services. No additional associations were observed. LIMITATIONS: The current study is based on cross-sectional data. Therefore, statements about causality cannot be made. CONCLUSIONS: These findings suggest that emotion regulation (e.g., daily mood fluctuations) and neurocognitive factors (e.g., difficulty with focusing attention) may be important factors to consider in the clinical assessment of Latino adolescents with SI.

ABSTRACT

BACKGROUND: A telemedicine program was developed between the Children's National Medical Center (CNMC) in Washington, DC, and the Sheikh Khalifa Bin Zayed Foundation in the United Arab Emirates (UAE). A needs assessment and a curriculum of on-site training conferences were devised preparatory to an ongoing telemedicine consultation program for children with neurodevelopmental disabilities in the underserved eastern region of the UAE. MATERIALS AND METHODS: Weekly telemedicine consultations are provided by a multidisciplinary faculty. Patients are presented in the UAE with their therapists and families. Real-time (video over Internet protocol; average connection, 768 kilobits/s) telemedicine conferences are held weekly following previews of medical records. A full consultation report follows each telemedicine session. RESULTS: Between February 29, 2012 and June 26, 2013, 48 weekly 1-h live interactive telemedicine consultations were conducted on 48 patients (28 males, 20 females; age range, 8 months-22 years; median age, 5.4 years). The primary diagnoses were cerebral palsy, neurogenetic disorders, autism, neuromuscular disorders, congenital anomalies, global developmental delay, systemic disease, and epilepsy. Common comorbidities were cognitive impairment, communication disorders, and behavioral disorders. Specific recommendations included imaging and DNA studies, antiseizure management, spasticity management including botulinum toxin protocols, and specific therapy modalities including taping techniques, customized body vests, and speech/language and behavioral therapy. Improved outcomes reported were in clinician satisfaction, achievement of therapy goals for patients, and requests for ongoing sessions. CONCLUSIONS: Weekly telemedicine sessions coupled with triannual training conferences were successfully implemented in a clinical program dedicated to patients with neurodevelopmental disabilities by the Center for Neuroscience at CNMC and the UAE government. International consultations in neurodevelopmental disabilities utilizing telemedicine services offer a reliable and productive method for joint clinical programs.

ABSTRACT

The ability to self-generate positive emotions is an important component of emotion regulation. In this study, we focus on children's latency to express positive emotions following challenging situations and assess whether this ability operates through early maternal sensitivity and children's effortful control. Longitudinal relations between maternal sensitivity, infant negative affect, effortful control, and latency to positive emotion following challenge were examined in 156 children who were 33 months of age. Structural equation models supported the hypothesis that maternal sensitivity during infancy predicted better effortful control and, in turn, shorter latencies to positive emotions following challenge at 33 months. Directions for future research are discussed.

ABSTRACT

Unlike other forms of disaster, terrorism is not confined to a particular place or time, and recent evidence indicates that the 9/11 terrorist attack was a significant macrolevel stressor affecting the health and mental health of United States citizens. No studies, however, have reported symptoms in toddlers and their mothers both before and after the attacks. To address this gap, we examined the effects of the 9/11 terrorist attacks on mothers and their 33-month-old toddlers. The attacks occurred during data collection at 33 months of a longitudinal study. Thirty-three-month-old toddlers and mothers who were assessed after the attacks were compared with those assessed before the attacks. When changes were examined from a previous wave of data collected at 15 months, those in the after-attack group showed poorer health, lower child acceptance, and marginally more anxiety, and their toddlers cried more and slept less, whereas the before-attack group showed no changes. Our findings contribute to research documenting widespread effects of the 9/11 terrorist attack on stress-related symptoms and suggest that greater attention must be placed on the needs of our youngest citizens and their caregivers.

ABSTRACT

Despite an extensive history underscoring the role of social processes and child contributions to the development of executive functions (C. Lewis & J. Carpendale, 2009; L. S. Vygotsky, 1987), research on these relations is sparse. To address this gap, 68 mother-child dyads were examined to determine whether maternal attention-directing behaviors (attention maintaining, attention redirection) and toddlers' temperament predicted executive processes during preschool (mean age = 4.5 years, SD = 0.46)-delay and conflict inhibition. Maternal attention maintaining was associated with high levels of conflict inhibition for inhibited and exuberant children, whereas attention redirection was associated with low levels of delay and conflict inhibition for inhibited children. Therefore, maternal attention-directing behaviors may enhance the development of executive functions but only for children with inhibited and exuberant temperaments.

ABSTRACT

PURPOSE: This study evaluated the safety and effectiveness of long-term enzyme replacement therapy with idursulfase (recombinant human iduronate-2-sulfatase) in patients with Hunter syndrome. METHODS: All 94 patients who completed a 53-week double-blinded study of idursulfase enrolled in this open-labeled extension study and received intravenous idursulfase at a dose of 0.5 mg/kg weekly for 2 years, and clinical outcomes and safety were assessed. RESULTS: No change in percent predicted forced vital capacity was seen, but absolute forced vital capacity demonstrated sustained improvement and was increased 25.1% at the end of the study. Statistically significant increases in 6-minute walking test distance were observed at most time points. Mean liver and spleen volumes remained reduced throughout the 2-year extension study. Mean joint range of motion improved for the shoulder and remained stable in other joints. Both the parent- and child-assessed Child Health Assessment Questionnaire Disability Index Score demonstrated significant improvement. Infusion-related adverse events occurred in 53% of patients and peaked at Month 3 of treatment and declined thereafter. Neutralizing IgG antibodies were detected in 23% of patients and seemed to attenuate the improvement in pulmonary function. CONCLUSIONS: Weekly infusions of idursulfase result in sustained clinical improvement during 3 years of treatment.

ABSTRACT

This study examined the moderating role of attentional control on relations between negative affect and action monitoring event related potentials (ERPs) (error-related negativity (ERN) and N2) in a group of healthy adolescents (9 to 17 years old). These ERPs were recorded while participants completed a modified flanker task. Participants also completed the negative affect subscale of the Positive and Negative Affect Schedule for Children (PANAS-C) and the attentional control subscale of the Early Adolescent Temperament Questionnaire-Revised (EATQ-R). Regression analyses revealed negative affect by attentional control interactions, suggesting that youth high in attentional control and high in negative affect show increased N2 amplitude and a trend toward increased ERN amplitude. These findings are discussed with regard to the interface of attention and emotion processes that are implicated in action monitoring and relevance to the study of self-regulation during adolescence.

ABSTRACT

Mouse embryonic stem cells (mESCs) maintain pluripotency and indefinite self-renewal through yet to be defined molecular mechanisms. Leukemia inhibitory factor has been utilized to maintain the symmetrical self-renewal and pluripotency of mESCs in culture. It has been suggested that molecules with significant cellular effects on retinoblastoma protein (pRb) or its related pathways should have functional impact on mESC proliferation and differentiation. However, the involvement of pRb in pluripotent differentiation of mESCs has not been extensively elaborated. In this paper, we present novel experimental data indicating that Cdk2ap1 (cyclin-dependent kinase 2-associating protein 1), an inhibitor of G(1)/S transition through down-regulation of CDK2 and an essential gene for early embryonic development, confers competency for mESC differentiation. Targeted disruption of Cdk2ap1 in mESCs resulted in abrogation of leukemia inhibitory factor withdrawal-induced differentiation, along with altered pRb phosphorylation. The differentiation competency of the Cdk2ap1(-/-) mESCs was restored upon the ectopic expression of Cdk2ap1 or a nonphosphorylatable pRb mutant (mouse Ser(788) --> Ala), suggesting that the CDK2AP1-mediated differentiation of mESCs was elicited through the regulation of pRb. Further analysis on mESC maintenance or differentiation-related gene expression supports the phosphorylation at serine 788 in pRb plays a significant role for the CDK2AP1-mediated differentiation of mESCs. These data clearly demonstrate that CDK2AP1 is a competency factor in the proper differentiation of mESCs by modulating the phosphorylation level of pRb. This sheds light on the role of the establishment of the proper somatic cell type cell cycle regulation for mESCs to enter into the differentiation process.
