Frequent first-trimester pregnancy loss in rhesus macaques infected with African-lineage Zika virus.

In the 2016 Zika virus (ZIKV) pandemic, a previously unrecognized risk of birth defects surfaced in babies whose mothers were infected with Asian-lineage ZIKV during pregnancy. Less is known about the impacts of gestational African-lineage ZIKV infections. Given high human immunodeficiency virus (HIV) burdens in regions where African-lineage ZIKV circulates, we evaluated whether pregnant rhesus macaques infected with simian immunodeficiency virus (SIV) have a higher risk of African-lineage ZIKV-associated birth defects. Remarkably, in both SIV+ and SIV- animals, ZIKV infection early in the first trimester caused a high incidence (78%) of spontaneous pregnancy loss within 20 days. These findings suggest a significant risk for early pregnancy loss associated with African-lineage ZIKV infection and provide the first consistent ZIKV-associated phenotype in macaques for testing medical countermeasures.

Changes in Caregiver Outcomes After Participation in the Engaged Eaters Program: A Caregiver-Mediated Feeding Intervention for Autistic Children and Their Families.

IMPORTANCE: Caregivers are essential partners in caregiver-mediated interventions that build on family routines and practices. Research identifying how participation as an intervention partner influences caregivers' outcomes, including stress and self-efficacy, is scarce. OBJECTIVE: To evaluate caregiver outcomes (stress, self-efficacy, and positive feeding responses and confidence) after participation in the Engaged Eaters Program. DESIGN: Quasi-experimental pretest-posttest design. SETTING: In-home via telehealth. PARTICIPANTS: Fourteen primary caregivers of an autistic child (ages 2-7 yr) with feeding challenges. INTERVENTION: The Engaged Eaters Program-Telehealth, a caregiver-mediated 6-mo in-home telehealth feeding intervention for autistic children ages 2 to 7 yr that included 24 intervention visits, eight caregiver training modules, and consultation with a dietician. OUTCOMES AND MEASURES: Relationships between child feeding challenge severity and caregiver outcomes and individual differences in caregivers' intervention responses were evaluated. We assessed caregivers' stress (Parenting Stress Index, Fourth Edition Short Form), self-efficacy (Parent Sense of Competence Scale), Positive Feeding Responses and Confidence (PFRC; composite score of items from other assessments), and individual intervention response using pre- to postintervention change in scores. RESULTS: Exploration of individual differences revealed that only caregivers with intake PFRC scores below the mean made significant improvements by the end of the intervention. No significant group-level changes were identified for stress, self-efficacy, or PFRC. Feeding challenge severity was not significantly related to caregiver outcomes. CONCLUSIONS AND RELEVANCE: The results emphasize the importance of considering baseline practices, efficacy, and caregiver confidence when engaging caregivers in intervention. Future research should explore the nuanced relationship between caregiver outcomes and child characteristics. Plain-Language Summary: Caregivers are essential partners with feeding interventions that build on family routines and practices. When working with caregivers, occupational therapists should consider caregivers' readiness for and responses to an intervention because intervention practices may differentially affect caregivers' parenting practices, confidence, and self-efficacy. Caregivers' responses may also affect the overall effectiveness of a caregiver-mediated intervention. Positionality Statement: The term caregiver-mediated in used throughout this article in place of parent-mediated to be inclusive of all types of caregivers.

Opening the door to university health research: recommendations for increasing accessibility for individuals with intellectual disability.

BACKGROUND: Advances in health equity rely on representation of diverse groups in population health research samples. Despite progress in the diversification of research samples, continued expansion to include systematically excluded groups is needed to address health inequities. One such group that is infrequently represented in population health research are adults with intellectual disability. Individuals with intellectual disability experience pervasive health disparities. Representation in population health research is crucial to determine the root causes of inequity, understand the health of diverse populations, and address health disparities. The purpose of this paper was to develop recommendations for researchers to increase the accessibility of university health research and to support the inclusion of adults with intellectual disability as participants in health research. METHODS: A comprehensive literature review, consultation with the university ethics review board, and review of United States federal regulations was completed to identify barriers to research participation for individuals with intellectual disability. A collaborative stakeholder working group developed recommendations and products to increase the accessibility of university research for participants with intellectual disability. RESULTS: Eleven key barriers to research participation were identified including gaps in researchers' knowledge, lack of trust, accessibility and communication challenges, and systematic exclusion among others. Together the stakeholder working group compiled seven general recommendations for university health researchers to guide inclusion efforts. Recommendations included: 1) address the knowledge gap, 2) build community partnerships, 3) use plain language, 4) simplify consent and assent processes, 5) establish research capacity to consent, 6) offer universal supports and accommodations, and 7) practice accessible dissemination. In addition, four products were created as part of the stakeholder working group to be shared with researchers to support the inclusion of participants with intellectual disability. 1) Supports I Need Checklist, 2) Plain language glossary of health and research terms, 3) Understanding Consent and Assent in Plain Language, 4) Easy-Read Paper Template. CONCLUSION: Community members and individuals with intellectual disability want to be included in research and are eager to engage as research participants. It is the responsibility of the researcher to open the door to university health research. The recommendations discussed in this paper could increase accessibility for a broader range of research participants and, in particular, promote the inclusion of individuals with intellectual disability to advance health equity in population health research.

Health Narratives as a Therapeutic Tool for Health Care Access for People with Intellectual and Developmental Disabilities.

Individuals with intellectual and developmental disabilities (IDD) have unique and complex health care needs that require health care access. Barriers, such as decreased health literacy and a lack of experienced physicians working with this population, make access to inclusive health care increasingly difficult. Therefore, it is important for occupational therapists to intentionally create opportunities to improve healthcare access and utilization for this population. This paper describes the collaborative health narrative development process as well as the inclusion of three examples created by co-authors with intellectual or developmental disability.

Parents' Strategies to Support Mealtime Participation of Their Children With Autism Spectrum Disorder.

OBJECTIVE: We identified and described the strategies parents use to support the mealtime participation of their child with autism spectrum disorder (ASD). METHOD: Twelve families with children with ASD (ages 2-7 yr) participated in videotaped mealtime observations. Qualitative content analysis was used to identify strategies families used to facilitate participation. RESULTS: Six categories were identified: (1) parent intervening and ignoring, (2) meal preparation and adaptability, (3) play and imagination, (4) distractions, (5) positive reinforcements, and (6) modeling. Props-common child objects that support the child's mealtime participation-were used in the context of multiple strategies. In addition, increased parental vigilance emerged as an important component of all family mealtimes. CONCLUSION: Families used multiple strategies within and across mealtimes, highlighting the individualistic nature of feeding challenges. Understanding parent mealtime strategies allows for further investigation into the efficacy and development of intervention strategies to promote mealtime participation of children with ASD.

Parent-Mediated Interventions for Children With Autism Spectrum Disorder: A Systematic Review.

OBJECTIVE: The purpose of this systematic review was to evaluate the evidence for the effectiveness of parent-mediated interventions on occupational performance of children with autism spectrum disorder (ASD). METHOD: We conducted a search of academic databases using terms such as autism spectrum disorder, parent, caregiver, and intervention. Five hundred eighty-two articles were reviewed, and 109 were selected for full-text review. The final analysis included 13 articles. RESULTS: Strong evidence was found for the efficacy of parent-mediated intervention for increasing child joint attention. Moderate evidence was found for the improvement of language scores, expressive language, nonverbal communication, initiation and response to interaction, behavior, play, adaptive functioning, ASD symptoms, and social communication. CONCLUSION: This systematic review suggests that parent-mediated interventions for children with ASD can improve various aspects of communication and ASD symptoms, with emerging support for occupational performance. Occupational therapy practitioners are well suited to facilitate these interventions to support families with children with autism.

Cross-species comparison of behavioral neurodevelopmental milestones in the common marmoset monkey and human child.

The common marmoset (Callithrix jacchus) is an increasingly popular non-human primate species for developing transgenic and genomic edited models of neurological disorders. These models present an opportunity to assess from birth the impact of genetic mutations and to identify candidate predictive biomarkers of early disease onset. In order to apply findings from marmosets to humans, a cross-species comparison of typical development is essential. Aiming to identify similarities, differences, and gaps in knowledge of neurodevelopment, we evaluated peer-reviewed literature focused on the first 6 months of life of marmosets and compared to humans. Five major developmental constructs, including reflexes and reactions, motor, feeding, self-help, and social, were compared. Numerous similarities were identified in the developmental sequences with differences often influenced by the purpose of the behavior, specifically for marmoset survival. The lack of detailed knowledge of marmoset development was exposed as related to the vast resources for humans.

Guided Imagery and Stress in Pregnant Adolescents.

OBJECTIVE: We examined the effects of a guided imagery intervention on perceived stress in pregnant adolescents. METHOD: Thirty-five pregnant adolescents recruited from a local alternative education program participated in a guided imagery intervention. Participants listened to a pregnancy-specific guided imagery recording on four separate occasions during their pregnancies. Perceived stress was measured immediately before and after each session using the Perceived Stress Measure-9 (PSM-9). RESULTS: Participants' pre- and postsession PSM-9 scores for three of the four sessions demonstrated a significant reduction in stress. Participants' baseline stress levels also decreased significantly across the four listening sessions. The greatest reductions in stress within and between sessions occurred in the early sessions, with effects diminishing over time. CONCLUSION: Pregnant teens experienced initial short- and long-term stress reduction during a guided imagery intervention, supporting the use of guided imagery to reduce stress in pregnant adolescents.

Sensory subtypes in children with autism spectrum disorder: latent profile transition analysis using a national survey of sensory features.

BACKGROUND: Sensory features are highly prevalent and heterogeneous among children with ASD. There is a need to identify homogenous groups of children with ASD based on sensory features (i.e., sensory subtypes) to inform research and treatment. METHODS: Sensory subtypes and their stability over 1 year were identified through latent profile transition analysis (LPTA) among a national sample of children with ASD. Data were collected from caregivers of children with ASD ages 2-12 years at two time points (Time 1 N = 1294; Time 2 N = 884). RESULTS: Four sensory subtypes (Mild; Sensitive-Distressed; Attenuated-Preoccupied; Extreme-Mixed) were identified, which were supported by fit indices from the LPTA as well as current theoretical models that inform clinical practice. The Mild and Extreme-Mixed subtypes reflected quantitatively different sensory profiles, while the Sensitive-Distressed and Attenuated-Preoccupied subtypes reflected qualitatively different profiles. Further, subtypes reflected differential child (i.e., gender, developmental age, chronological age, autism severity) and family (i.e., income, mother's education) characteristics. Ninety-one percent of participants remained stable in their subtypes over 1 year. CONCLUSIONS: Characterizing the nature of homogenous sensory subtypes may facilitate assessment and intervention, as well as potentially inform biological mechanisms.

The characterization of feeding challenges in autistic children.

LAY ABSTRACT: Feeding challenges are common for autistic children. Currently, research and intervention for feeding challenges focuses on single factors (e.g. behavior or sensory). Research is needed to understand the complexity of feeding challenges. This study provides a comprehensive description of feeding challenges. Furthermore, this study identifies what factors predict the severity and type of feeding challenges experienced by autistic children. Using the Survey for Characterization of Feeding Challenges in Autistic Children-United States, 427 caregivers of autistic children provided information about their child's feeding challenges. Children were between the ages of 2 and 12 with an average age of 8.42 years. Children in the study had a wide variety of feeding difficulties including challenges in early childhood, sensory challenges, difficulty with family mealtime, and variable self-help skills. On average children's feeding challenges were present prior to their autism diagnosis. We found that children who had early feeding challenges had more severe feeding challenges in later childhood. Also, specific early feeding challenges predicted the types of feeding challenges children would have later in childhood. For example, children who had difficulty transitioning to table foods and who continued to restrict their diet over time were more likely to have sensory-based feeding challenges. Results from this study show how feeding challenges present in a wide variety of ways for autistic children. The findings also highlight the importance of screening for feeding challenges in early childhood and collaborating with families to understand individualized feeding challenge experiences. These results could be used to inform evaluation and intervention for feeding.

Quality of life, satisfaction with care, and the experiences of adults with intellectual and developmental disabilities before and during COVID-19.

BACKGROUND: Adults with intellectual and developmental disabilities (IDD) experienced significant disruptions in their access to health care, support services, and essential daily activities such as work, leisure, and routine daily care during COVID-19. OBJECTIVE: The purpose of this study was to describe overall experiences related to COVID-19 among adults with IDD, including the vaccination process, quality of life (QoL), and service satisfaction before and during the pandemic. METHODS: A longitudinal statewide survey of adults with IDD receiving long-term care support using a combination of self- and care partner report was completed prior to (2017; n = 331) and during (2021; n = 206) the pandemic. RESULTS: Qualitative results identified specific vaccine barriers, vaccine decision influencers, and general experiences during COVID-19 for adults with IDD. The importance of support staff, vaccine availability, disruption in daily activities, social context, and mental health implications were noted in responses to all three topics. Quantitative results showed lower QoL during COVID-19 (M = 2.99 vs. 3.14, p = .028); however, when reporter (self vs. care partner) and age were added to the model, differences between pre-vs. during-COVID were no longer significant. No significant differences in satisfaction of services were noted pre-vs. during-COVID-19. Ninety-six percent of respondents reported access to the vaccine, and 16 % experienced barriers getting the vaccine. QoL was associated with receiving the COVID-19 vaccine (r = 0.15, p = .036), level of agreement that the vaccine is safe (r = 0.17, p = .024), and level of agreement that getting the vaccine will help protect other vulnerable people in the community (r = .25, p = .001). Level of satisfaction with quality of services was also associated with level of agreement that the vaccine is safe (r = 0.15, p = .048). CONCLUSIONS: Overall, a better understanding of service continuation, support practices, and experiences related to COVID-19 will prepare us for future environmental and health crises by identifying areas for improvement, intervention, and policy change to meet the ongoing needs of adults with IDD.

"Giving Me the Self-Confidence to Tackle It": Mothers' Experiences Participating In The Engaged Eaters Program, A Caregiver-Mediated Feeding Intervention.

The purpose of this study was to understand caregivers' experience of participating in a caregiver-mediated in-home feeding intervention, the Engaged Eaters Program, for their young autistic child. This qualitative study utilized a thematic approach to analyze post-intervention semi-structured interviews with thirteen mothers of autistic children between the ages of 2 to 7 years after they participated in the intervention. Interview questions focused on the child and family experience, what worked well, what could be improved, and how the intervention integrated into family routines. Four major themes were identified: In-Home Intervention, Parent Skill and Knowledge, Increased Social Participation, and Parent Responsibilities and Challenges. Sub-themes provided descriptions of learning practical tools to support their child, increasing self-efficacy, and impacts on family life. Mothers described an increase in tangible skills that were easily practiced in the home environment that improved their confidence and self-efficacy in feeding their children. They also described how participation did require more work and time commitment for them beyond their regular responsibilities. The caregiver experience is essential to understand for intervention effectiveness while simultaneously addressing child, caregiver, and family needs. By focusing on the mothers' experiences, individualized needs, and self-efficacy, we were able to better understand how integrating an intervention into the family context and daily routines may be beneficial for the whole family.

Sensorimotor Features and Daily Living Skills in Autistic Children With and Without ADHD.

Attention-deficit/hyperactivity disorder (ADHD) commonly co-occurs in autistic children. However, additional research is needed to explore the differences in motor skills and sensory features in autistic children with and without ADHD, as well as the impacts of these factors on daily living skills (DLS). This observational study sought to fill this gap with 67 autistic children (6.14-10.84 years-old), 43 of whom had ADHD. Autistic children with ADHD demonstrated higher sensory features and lower motor skills than autistic children without ADHD. In examining autism and ADHD features dimensionally, we found that overall sensory features, seeking, and hyporesponsiveness were driven by both autism and ADHD features, whereas motor skills, enhanced perception, and hyperresponsiveness were driven by only autism features. Additionally, in using these dimensional variables of autism and ADHD features, we found that differences in motor skills, sensory and autism features, but not ADHD features, impact DLS of autistic children, with autism features and motor skills being the strongest individual predictors of DLS. Together, these results demonstrate the uniqueness of motor skills and sensory features in autistic children with and without ADHD, as well as how autism features, sensory features, and motor skills contribute to DLS, emphasizing the importance of a comprehensive understanding of each individual and complexities of human development when supporting autistic children.

Benefits and Challenges of a Telehealth Eating and Mealtime Intervention for Autistic Children: Occupational Therapy Practitioners' Perspectives.

Eating and mealtime challenges are common in autistic children, yet intervention access is limited. Telehealth may provide opportunities to address this gap and increase access for underserved families. This study examined the occupational therapy practitioner's perceptions of transitioning from a caregiver-mediated, in-home eating, and mealtime intervention for autistic children to telehealth owing to COVID-19 while considering the impact on accessibility, challenges, and benefits. Family characteristics were compared between groups. Thematic analysis of semi-structured interviews explored practitioners' experiences of telehealth. Statistical findings and themes were directly compared and contrasted. The following three themes emerged: Intervention Adaptations, Challenges for Interventionists, and Benefits of Telehealth. The differences in the families' geographic location were identified. Themes and family characteristic differences supported increased intervention accessibility for the telehealth group. This study provides preliminary evidence that telehealth can increase access to specialized services. There are benefits and challenges to implementing telehealth with families and autistic children.

Quantification of early gait development: Expanding the application of Catwalk technology to an infant rhesus macaque model.

BACKGROUND: Understanding gait development is essential for identifying motor impairments in neurodevelopmental disorders. Defining typical gait development in a rhesus macaque model is critical prior to characterizing abnormal gait. The goal of this study was to 1) explore the feasibility of using the Noldus Catwalk to assess gait in infant rhesus macaques and 2) provide preliminary normative data of gait development during the first month of life. NEW METHOD: The Noldus Catwalk was used to assess gait speed, dynamic and static paw measurements, and interlimb coordination in twelve infant rhesus macaques at 14, 21, and 28 days of age. All macaque runs were labeled as a diagonal or non-diagonal walking pattern. RESULTS: Infant rhesus macaques primarily used a diagonal (mature) walking pattern as early as 14 days of life. Ten infant rhesus macaques (83.3%) were able to successfully walk across the Noldus Catwalk at 28 days of life. Limited differences in gait parameters were observed between timepoints because of the variability within the group at 14, 21, and 28 days. COMPARISON WITH EXISTING METHODS: No prior gait analysis system has been used to provide objective quantification of gait parameters for infant macaques. CONCLUSIONS: The Catwalk system can be utilized to quantify gait in infant rhesus macaques less than 28 days old. Future applications to infant rhesus macaques could provide a better understanding of gait development and early differences within various neurodevelopmental disorders.

Examining the Latent Structure and Correlates of Sensory Reactivity in Autism: A Multi-site Integrative Data Analysis by the Autism Sensory Research Consortium.

Background Differences in responding to sensory stimuli, including sensory hyperreactivity (HYPER), hyporeactivity (HYPO), and sensory seeking (SEEK) have been observed in autistic individuals across sensory modalities, but few studies have examined the structure of these "supra-modal" traits in the autistic population. Methods Leveraging a combined sample of 3,868 autistic youth drawn from 12 distinct data sources (ages 3-18 years and representing the full range of cognitive ability), the current study used modern psychometric and meta-analytic techniques to interrogate the latent structure and correlates of caregiver-reported HYPER, HYPO, and SEEK within and across sensory modalities. Bifactor statistical indices were used to both evaluate the strength of a "general response pattern" factor for each supra-modal construct and determine the added value of "modality-specific response pattern" scores (e.g., Visual HYPER). Bayesian random-effects integrative data analysis models were used to examine the clinical and demographic correlates of all interpretable HYPER, HYPO and SEEK (sub)constructs. Results All modality-specific HYPER subconstructs could be reliably and validly measured, whereas certain modality-specific HYPO and SEEK subconstructs were psychometrically inadequate when measured using existing items. Bifactor analyses unambiguously supported the validity of a supra-modal HYPER construct (ω H = .800), whereas a coherent supra-modal HYPO construct was not supported (ω H = .611), and supra-modal SEEK models suggested a more limited version of the construct that excluded some sensory modalities (ω H = .799; 4/7 modalities). Within each sensory construct, modality-specific subscales demonstrated substantial added value beyond the supra-modal score. Meta-analytic correlations varied by construct, although sensory features tended to correlate most strongly with other domains of core autism features and co-occurring psychiatric symptoms. Certain subconstructs within the HYPO and SEEK domains were also associated with lower adaptive behavior scores. Limitations: Conclusions may not be generalizable beyond the specific pool of items used in the current study, which was limited to parent-report of observable behaviors and excluded multisensory items that reflect many "real-world" sensory experiences. Conclusion Psychometric issues may limit the degree to which some measures of supra-modal HYPO/SEEK can be interpreted. Depending on the research question at hand, modality-specific response pattern scores may represent a valid alternative method of characterizing sensory reactivity in autism.

Examining the latent structure and correlates of sensory reactivity in autism: a multi-site integrative data analysis by the autism sensory research consortium.

Bifactor analyses supported the validity of a supra-modal HYPER construct (ωH = .800) but not a supra-modal HYPO construct (ωH = .653), and supra-modal SEEK models suggested a more limited version of the construct that excluded some sensory modalities (ωH = .800; 4/7 modalities). Modality-specific subscales demonstrated significant added value for all response patterns. Meta-analytic correlations varied by construct, although sensory features tended to correlate most with other domains of core autism features and co-occurring psychiatric symptoms (with general HYPER and speech HYPO demonstrating the largest numbers of practically significant correlations). LIMITATIONS: Conclusions may not be generalizable beyond the specific pool of items used in the current study, which was limited to caregiver report of observable behaviors and excluded multisensory items that reflect many "real-world" sensory experiences. CONCLUSION: Of the three sensory response patterns, only HYPER demonstrated sufficient evidence for valid interpretation at the supra-modal level, whereas supra-modal HYPO/SEEK constructs demonstrated substantial psychometric limitations. For clinicians and researchers seeking to characterize sensory reactivity in autism, modality-specific response pattern scores may represent viable alternatives that overcome many of these limitations.

Evaluating depression- and anxiety-like behaviors in non-human primates.

Depression and anxiety are some of the most prevalent and debilitating mental health conditions in humans. They can present on their own or as co-morbidities with other disorders. Like humans, non-human primates (NHPs) can develop depression- and anxiety-like signs. Here, we first define human depression and anxiety, examine equivalent species-specific behaviors in NHPs, and consider models and current methods to identify and evaluate these behaviors. We also discuss knowledge gaps, as well as the importance of evaluating the co-occurrence of depression- and anxiety-like behaviors in animal models of human disease. Lastly, we consider ethical challenges in depression and anxiety research on NHPs in order to ultimately advance the understanding and the personalized treatment of these disorders.

Accessibility and Inclusion for Families with Children with Autism Spectrum Disorders in Cultural Institutions.

This project aimed to develop a comprehensive set of evaluation tools to assess the accessibility and inclusion of families with children on the autism spectrum in cultural institutions. A stakeholder team conducted interviews, reviewed museum artifacts, and observed museum programming. An evaluation toolkit was constructed by incorporating best practices from current literature and collected data. Tools were piloted and revised after being implemented in the museum context. The Toolkit to Increase Accessibility and Inclusion for Children on the Autism Spectrum and with Sensory Processing Differences in Cultural Institutions was developed with five unique tools, the Dimensions of Accessibility framework, and further resources to provide a self-assessment of cultural institutions. The toolkit can be used broadly across many types of institutions and self-assessment can lead to proactive development of public spaces, institutions, and programming that is accessible and inclusive of diverse groups of people, beyond families with children on the autism spectrum.
