ABSTRACT

Children with autism spectrum disorder and developmental disabilities (ASD/DD) face barriers to participation in health promotion programs due to the lack of available and/or affordable programs and trained staff at recreation centers. Children with ASD/DD in Korean immigrant families are one of the most underserved minority groups due to language, racial/ethnic discrimination, and stigma and shame within their own ethnic community. However, little research is available on development, implementation, and evaluation of a culturally adapted community health promotion program in this population. The purpose of this study is to assess effectiveness of a pilot program for children with ASD/DD from first-generation Korean immigrant families. The pilot study used a quantitative, quasiexperimental design (one-group design with pre- and posttest) following a seven-week health promotion program. We recruited 15 children with ASD/DD, ages nine through 16, from first-generation Korean immigrant families. The findings of the study suggest that the pilot program was effective in gaining nutrition knowledge and increasing physical involvement among participants. Given the fact that Asian immigrants are a fast-growing population and that nearly 75 percent of them were born abroad, development and evaluation of a community-based, culturally adapted health promotion program is urgently needed.

ABSTRACT

Hispanic/Latinx individuals disproportionately experience intimate partner violence (IPV) compared to their non-Hispanic/Latinx counterparts, and little is known about IPV among college-aged Hispanic/Latinx students. This study examines the rates of IPV victimization and perpetration and their correlates among Hispanic/Latinx and non-Hispanic White college students by analyzing cross-sectional survey data of 3,397 Hispanic/Latinx and White college students enrolled in seven universities. Compared to their White counterparts, Hispanic/Latinx students reported higher rates of IPV victimization and perpetration. Age, gender, drug use, and adverse childhood experience were associated with both IPV victimization and perpetration, while ethnicity was only associated with IPV perpetration. This study's findings highlight the urgent need for more culturally sensitive IPV prevention services and responses to support Hispanic/Latinx college students.

ABSTRACT

The study examined the effect of community environments, such as community cohesion, community safety, and community poverty, in childhood on the likelihood of Intimate Partner Violence (IPV) perpetration and victimization in young adulthood. The study used the cross-sectional survey data of 2,082 college students collected in 2016-2017 from six universities in the U.S. and the data for the childhood community environment from the 2007-2011 American Community Survey. Hierarchical regressions were performed separately by gender to 1) assess the effects of community factors in addition to individual factors for IPV perpetration and victimization, and to 2) identify the interaction effect of community cohesion with community poverty on IPV perpetration and victimization. Community factors of community cohesion and community poverty were significantly correlated to different types of IPV. For IPV perpetration, only community cohesion was significant for, the interaction effect between community cohesion and poverty showed that higher community cohesion lowered the risk of community poverty on later IPV perpetration in both genders. For IPV victimization, only female students were affected by community poverty, whereas none of the community factors had an impact on male students. The findings imply the significance of early interventions and policies strengthening the community environment, especially community cohesion, for preventing IPV. The findings also suggest that assessing risk and protective factors on IPV in multiple contexts during childhood is important to develop effective programs preventing IPV.

ABSTRACT

Adverse childhood experiences (ACEs) are early traumatic events that can have adverse long-term developmental effects on a person's health and well-being. Individuals with disabilities are at a greater risk of all types of ACEs. However, the impact of having a disability and neighbourhood context on ACEs is under-researched, and even less is known about whether neighbourhood cohesion and safety affect the relationship between disability status and ACEs. The purpose of this study is to examine the direct and indirect pathways between disability status, childhood neighbourhood environment and ACEs. The final study sample of this study was 2,049 college students, consisting of 494 students with disabilities and 1,555 students without disabilities from six universities in the U.S. and Canada between March 2016 and June 2017. Data analysis included Pearson correlations and structural equation modelling procedures using Stata 16 software to test a partial mediation model. Having a disability has both a direct effect and an indirect effect through the neighbourhood environment on ACEs after controlling for socio-demographic characteristics associated with neighbourhood environment or ACEs. The findings suggest that neighbourhood cohesion and safety can be a mediator between disability status and ACEs, and the potential cumulative risk and protective factors that can contribute to ACEs. To elucidate the relationship between disability status and a higher risk for ACEs fully and prevent ACEs that can negatively impact the long-term health outcomes, greater attention to environmental risk and protective factors is urgently needed.

ABSTRACT

This study applied Andersen's Model of Health Service Use to examine help-seeking behaviors for intimate partner violence (IPV) and predisposing, enabling, and need factors for help-seeking among college students. The sample (N = 2,719) consisted of those who experienced IPV and was recruited from six universities in the United States and one university in Canada through an online survey. Results showed that 45.4% of the sample had sought some form of help for IPV. The most utilized source of formal help was from medical services, and friends were the number one source of informal help. Gender, age, sexual orientation (predisposing factors), IPV training (enabling factor), experiencing psychological and technological violence, and IPV consequences (need factors) were associated with seeking help. Implications for research and practice are discussed.

ABSTRACT

ABSTRACT: Biologic factors that predict risk for and mediate the development of common outcomes of trauma exposure such as chronic posttraumatic pain (CPTP) are poorly understood. In the current study, we examined whether peritraumatic circulating 17ß-estradiol (E2) levels influence CPTP trajectories. 17ß-estradiol levels were measured in plasma samples (n = 254) collected in the immediate aftermath of trauma exposure from 3 multiethnic longitudinal cohorts of men and women trauma survivors. Chronic posttraumatic pain severity was evaluated 6 weeks, 6 months, and 1 year after traumatic stress exposure. Repeated measures mixed models were used to test the relationship between peritraumatic E2 levels and prospective CPTP. Secondary analyses in a nested cohort assessed the influence of participant body mass index on the E2-CPTP relationship. In women, a statistically significant inverse relationship between peritraumatic E2 and CPTP was observed (ß = -0.280, P = 0.043) such that higher E2 levels predicted lower CPTP severity over time. Secondary analyses identified an E2 * body mass index interaction in men from the motor vehicle collision cohort such that obese men with higher E2 levels were at greater risk of developing CPTP. In nonobese men from the motor vehicle collision cohort and in men from the major thermal burn injury cohort, no statistically significant relationship was identified. In conclusion, peritraumatic circulating E2 levels predict CPTP vulnerability in women trauma survivors. In addition, these data suggest that peritraumatic administration of E2 might improve CPTP outcomes for women; further research is needed to test this possibility.

ABSTRACT

Synaptic activity in neurons leads to the rapid activation of genes involved in mammalian behavior. ATP-dependent chromatin remodelers such as the BAF complex contribute to these responses and are generally thought to activate transcription. However, the mechanisms keeping such "early activation" genes silent have been a mystery. In the course of investigating Mendelian recessive autism, we identified six families with segregating loss-of-function mutations in the neuronal BAF (nBAF) subunit ACTL6B (originally named BAF53b). Accordingly, ACTL6B was the most significantly mutated gene in the Simons Recessive Autism Cohort. At least 14 subunits of the nBAF complex are mutated in autism, collectively making it a major contributor to autism spectrum disorder (ASD). Patient mutations destabilized ACTL6B protein in neurons and rerouted dendrites to the wrong glomerulus in the fly olfactory system. Humans and mice lacking ACTL6B showed corpus callosum hypoplasia, indicating a conserved role for ACTL6B in facilitating neural connectivity. Actl6b knockout mice on two genetic backgrounds exhibited ASD-related behaviors, including social and memory impairments, repetitive behaviors, and hyperactivity. Surprisingly, mutation of Actl6b relieved repression of early response genes including AP1 transcription factors (Fos, Fosl2, Fosb, and Junb), increased chromatin accessibility at AP1 binding sites, and transcriptional changes in late response genes associated with early response transcription factor activity. ACTL6B loss is thus an important cause of recessive ASD, with impaired neuron-specific chromatin repression indicated as a potential mechanism.

ABSTRACT

To better understand disparities between Latino and White children with autism or other developmental disabilities (ASD/DD), we examined whether Latino ethnicity predicted the number of specialty care services received by children with severe functional limitations depending on medical providers' responses to parents' initial concerns about their child's development. Through linkage of the Pathways and NS-CSHCN datasets, we found ethnic disparities in the receipt of specialty services associated with providers' responsiveness to parent-reported concerns among children with ASD/DD. Among children with significant functional limitations, Latino children whose parents received passive/reassuring responses from their providers were less likely to receive specialty services than White children with ASD/DD. Providers' guidance to parents may be a promising point of intervention for future disparity reduction efforts.

ABSTRACT

Advances in stem cell science allow the production of different cell types in vitro either through the recapitulation of developmental processes, often termed 'directed differentiation', or the forced expression of lineage-specific transcription factors. Although cells produced by both approaches are increasingly used in translational applications, their quantitative similarity to their primary counterparts remains largely unresolved. To investigate the similarity between in vitro-derived and primary cell types, we harvested and purified mouse spinal motor neurons and compared them with motor neurons produced by transcription factor-mediated lineage conversion of fibroblasts or directed differentiation of pluripotent stem cells. To enable unbiased analysis of these motor neuron types and their cells of origin, we then subjected them to whole transcriptome and DNA methylome analysis by RNA sequencing (RNA-seq) and reduced representation bisulfite sequencing (RRBS). Despite major differences in methodology, lineage conversion and directed differentiation both produce cells that closely approximate the primary motor neuron state. However, we identify differences in Fas signaling, the Hox code and synaptic gene expression between lineage-converted and directed differentiation motor neurons that affect their utility in translational studies.

ABSTRACT

An intronic GGGGCC repeat expansion in C9ORF72 is the most common cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), but the pathogenic mechanism of this repeat remains unclear. Using human induced motor neurons (iMNs), we found that repeat-expanded C9ORF72 was haploinsufficient in ALS. We found that C9ORF72 interacted with endosomes and was required for normal vesicle trafficking and lysosomal biogenesis in motor neurons. Repeat expansion reduced C9ORF72 expression, triggering neurodegeneration through two mechanisms: accumulation of glutamate receptors, leading to excitotoxicity, and impaired clearance of neurotoxic dipeptide repeat proteins derived from the repeat expansion. Thus, cooperativity between gain- and loss-of-function mechanisms led to neurodegeneration. Restoring C9ORF72 levels or augmenting its function with constitutively active RAB5 or chemical modulators of RAB5 effectors rescued patient neuron survival and ameliorated neurodegenerative processes in both gain- and loss-of-function C9ORF72 mouse models. Thus, modulating vesicle trafficking was able to rescue neurodegeneration caused by the C9ORF72 repeat expansion. Coupled with rare mutations in ALS2, FIG4, CHMP2B, OPTN and SQSTM1, our results reveal mechanistic convergence on vesicle trafficking in ALS and FTD.

ABSTRACT

There is a dearth of existing research on the treatment of reproductive cancers among women with intellectual and developmental disabilities (IDD). This study analyzed the 2010 Healthcare Cost and Utilization Project Nationwide Inpatient Sample and compared the prevalence of reproductive cancer treatment hospitalization discharges among women with and without IDD. Discharges linked to women with IDD had higher incidences of cancer of the uterus and lower prevalence of cancer of the cervix. Moreover, discharges linked to women with IDD indicated these women were younger, had longer hospital stays, and were more likely to have public insurance coverage. Therefore, further research and targeted interventions to increase cancer prevention and screening are urgently needed.

ABSTRACT

Children with special health-care needs (CSHCNs) face notable barriers to health-care access and to receiving quality and family-centered care, despite higher health-care utilization rates. Within the population of CSHCNs, there are significant inequities in health-care quality impacting immigrants who have migrated to the United States. However, little is known about the experiences and needs of Asian immigrant families who have CSHCNs. This study aimed to explore how Asian immigrant parents of CSHCNs view their child's health-care access, quality, and utilization. We conducted semi-structured qualitative interviews with 22 Vietnamese- and Cantonese-speaking parents of CSHCNs. Participants were recruited through community partners. Interviews were transcribed, translated, and coded using content analysis. Participants were generally satisfied with their children's care and had strong relationships with their primary care doctors who were often culturally 'matched'. However, participants experienced several important and culturally specific barriers, including gaps in their understanding of the health-care system, language barriers, and a sense of alienation. Parents frequently turned to informal and community supports for assistance in navigating the US health-care system. Further research to understand the drivers of health disparities and policy level solutions is warranted.

ABSTRACT

Purpose: To provide estimates for the prevalence of parent-reported speech-language difficulties in U.S. children, and to describe the levels of health care access and material hardship in this population. Method: We tabulated descriptive and bivariate statistics using cross-sectional data from the 2007 and 2011/2012 iterations of the National Survey of Children's Health, the 2005/2006 and 2009/2010 iterations of the National Survey of Children with Special Health Care Needs, and the 2004 and 2008 panels of the Survey of Income and Program Participation. Results: Prevalence estimates ranged from 1.8% to 5.0%, with data from two of the three surveys preliminarily indicating increased prevalence in recent years. The largest health care challenge was in accessing care coordination, with 49%-56% of children with parent-reported speech-language difficulties lacking full access. Children with parent-reported speech-language difficulties were more likely than peers without any indications of speech-language difficulties to live in households experiencing each measured material hardship and participating in each measured public benefit program (e.g., 20%-22% experiencing food insecurity, compared to 11%-14% of their peers without any indications of speech-language difficulties). Conclusions: We found mixed preliminary evidence to suggest that the prevalence of parent-reported speech-language difficulties among children may be rising. These children face heightened levels of material hardship and barriers in accessing health care.

ABSTRACT

There is a dearth of information on the quality of health care for Asian American children and particularly Asian children with special health care needs (CSHCN). The goal of this article was to determine whether there were disparities in quality of health care for Asian CSHCN, whose experiences have not been studied. Data were derived from the 2009-2010 National Survey of Children with Special Health Care Needs (ns = 355 non-Hispanic Asian children and 4,343 non-Hispanic white CSHCN). Bivariate and multivariate logistic regression analyses were conducted to examine the relationship between racial identity (that is, non-Hispanic white and non-Hispanic Asian) and quality of health care. Racial disparities in quality of health care were substantial between Asian and white CSHCN in 2009-2010. Asian parents were significantly less likely than white parents to report that their health care provider provided the specific information they needed, helped them feel like a partner in their child's care, and was sensitive to the family's values and customs. The development and testing of specific, targeted policy and practice interventions to reduce disparities in health care quality for these children are urgently needed.

ABSTRACT

Objective This study compared health care utilization of children with special health care needs in 2005/06 and 2009/10. Methods Using data from the National Survey of Children with Special Health Care Needs, this study compared the health care utilization of children with special health care needs in 2005/06 (n = 40,723) and 2009/10 (n = 40,242). Descriptive statistics characterize the sample during the 2005/06 and 2009/10 surveys. Logistic regression models examined the unmet needs for specific health care and support services, delayed care, coordinated care, and medical home. Results Compared to 2005/06, in 2009/10 children with special health care needs had greater unmet dental and therapy needs and less care coordination of health services as well as access to medical home services. Conclusions These findings indicate that additional measures are needed to improve the health care access of children with special health care needs.

ABSTRACT

The aim of this study was to determine if racial and ethnic disparities in the quality of provider interaction have changed between 2006 and 2010 for children with developmental disabilities and autism spectrum disorders (ASD). Data from the 2005/2006 and 2009/2010 National Survey of Children With Special Health Care Needs were analyzed. Results show that racial and ethnic disparities in the quality of provider interactions were substantial in both 2005/2006 and 2009/2010. Black and Latino parents were significantly less likely than White parents to report that their provider spent enough time with their child and was sensitive to the family's values. Racial and ethnic disparities in health care quality were found to be unchanged over time. Research and policy implications are discussed.

ABSTRACT

The existing research on pregnancy outcomes for women with intellectual and developmental disabilities (IDD) is sparse. This study analyzed the 2010 Healthcare Cost and Utilization Project Nationwide Inpatient Sample and compared deliveries among women with IDD (n = 340) to the general obstetric population. Women with IDD had longer hospital stays and were more likely to have Caesarean deliveries in contrast to other women. Rates of adverse pregnancy outcomes were elevated for women with IDD across a range of measures, including early labor, preterm birth, and preeclampsia, and their infants were more likely to have low birth weight, even after adjusting for age, race, ethnicity, and insurance type. Targeted interventions are needed to address these deleterious outcomes.

ABSTRACT

The BAF (mammalian SWI/SNF) complexes are a family of multi-subunit ATP-dependent chromatin remodelers that use ATP hydrolysis to alter chromatin structure. Distinct BAF complex compositions are possible through combinatorial assembly of homologous subunit families and can serve non-redundant functions. In mammalian neural development, developmental stage-specific BAF assemblies are found in embryonic stem cells, neural progenitors and postmitotic neurons. In particular, the neural progenitor-specific BAF complexes are essential for controlling the kinetics and mode of neural progenitor cell division, while neuronal BAF function is necessary for the maturation of postmitotic neuronal phenotypes as well as long-term memory formation. The microRNA-mediated mechanism for transitioning from npBAF to nBAF complexes is instructive for the neuronal fate and can even convert fibroblasts into neurons. The high frequency of BAF subunit mutations in neurological disorders underscores the rate-determining role of BAF complexes in neural development, homeostasis, and plasticity.
