Assessing Community Needs for Autism Spectrum Disorder: A Review of Rural/Frontier Needs Through Community Outreach With Developmental Pediatrics.

Early intervention is known to improve long-term outcomes for individuals with autism spectrum disorder (ASD). Access barriers to care limit timely engagement with supportive services. This report characterized the community needs and supportive services for children and families with suspected or diagnosed ASD. Families and providers participating in outreach clinics identified available services and their attitudes about support for ASD diagnosis. Chart reviews provided referral history, insurance, and current services. Children were nearly 6 years old, 95% of families relied on public health insurance, whereas 50% reported traveling 11 miles or greater for supportive services. Most providers (83%) were medically trained in primary care and placed 1-5 referrals per month to a tertiary referral hospital. Providers reported travel difficulty as the primary reason for referring patients for evaluation. Multiple barriers for supportive services were identified, highlighting the importance to increase the capacity and availability of local ASD supportive services.

Cultural relevance of fine motor domain of the ASQ in Guatemala.

Previous research suggests that the Ages and Stages Questionnaire-3rd ed. (ASQ) fine motor domain (FMD) may not be culturally relevant for developmental screening in a rural Guatemalan community, as the FMD accounts for 40% of all abnormal screenings after a needs assessment in this community. We hypothesize this is due to a lack of exposure to objects assessed in the questionnaire, such as blocks or light switches. The FMD scores of rural Guatemalan children (n = 56) participating in a child development program were compared with Spanish- and English-speaking Latinx-American children attending a US primary care clinic and screened at yearly well-child checks. Groups were matched for age gender, and socioeconomic status. Item-level analyses explored differences across the three groups. In the Guatemalan sample, the FMD abnormal score rates were 16%, 62%, and zero in the 12-, 24-, and 36-month-old children, respectively. Abnormal scores for the Guatemalan sample on the 24-month ASQ-3 significantly differed (p = .01) when compared to the Latinx-American groups. The 24-month questionnaire has more questions about objects than the 12- and 36-month questionnaires, which may explain the higher rates of abnormal scores. Developmental screening with ASQ-3 may not adequately capture the skills of children in similar communities.

La investigación previa ha sugerido que el dominio de motricidad fina (FMD) del Cuestionario de Edades y Etapas - Tercera edición (ASQ) pudiera no ser culturalmente relevante para examinar el desarrollo en una comunidad rural de Guatemala, ya que el FMD representa el 40% de todas las examinaciones anormales después de la evaluación de necesidades en esta comunidad. Nuestra hipótesis es que esto se debe a la falta de exposición a objetos evaluados en el cuestionario, tales como bloques o interruptores de luz. Se compararon los puntajes del FMD de niños de áreas rurales en Guatemala (n=56) que participan en un programa de desarrollo del niño con niños norteamericanos latin-x hablantes del español y del inglés, quienes asisten a una clínica de cuidado primario y son examinados en chequeos anuales de rutina para niños sanos. Se clasificaron los grupos según la edad, el género y la condición económica. Los análisis del nivel de cada punto exploraron las diferencias a lo largo de los 3 grupos. En el grupo muestra de Guatemala, los índices de puntajes anormales de FMD fueron 16%, 62% y cero en los niños de 12, 24 y 36 meses de edad, respectivamente. Los puntajes anormales para el grupo de Guatemala en el ASQ-3 a los 24 meses significativamente difirieron (p=0.01) cuando se les comparó con los grupos muestras norteamericanos latin-x. El cuestionario para la edad de 24 meses tiene más preguntas acerca de objetos que los cuestionarios para las edades de 12 y 36 meses, lo cual pudiera explicar los más altos índices de puntajes anormales. La examinación del desarrollo con ASQ-3 pudiera no captar adecuadamente las destrezas de niños en comunidades similares.

Les recherches précédentes suggèrent que le domaine de la motricité fine (FMD en anglais) du Questionnaire des Ages et des Etapes - 3e édition (ASQ en anglais) pourrait ne pas être pertinent sur le point culturel pour le dépistage développemental dans une communauté rurale du Guatémala puisque le FMD explique 40% de tous les dépistages anormaux après une évaluation des besoins dans cette communauté. Nous émettons l'hypothèse que cela est dû au manque d'exposition à des objets évalués dans le questionnaire, comme des blocs ou des interrupteurs (électricité). Les scores de FMD d'enfants de milieu rural au Guatémala (n=56) participant à un programme de développement de l'enfant ont été comparés à ceux d'enfants Latinx-Américains parlant espagnol et anglais, patients d'une clinique de soins primaires aux Etats-Unis d'Amérique et dépisté avec des contrôles de santé annuels. Les groupes ont été assortis par groupe de genre et de statut socioéconomique. Des analyses de précision ont exploré les différences entre les 3 groupes. Dans l'échantillon du Guatémala les taux de score anormal FMD étaient de 16%, 62% et zéro chez les enfants de 12, 24 et 36 mois, respectivement. Les scores anormaux pour l'échantillon du Guatémala pour le ASQ-3 à 24 moi a différé de manière importante (p=0.01) lors de la comparaison aux groupes Latinx-Américains. Le questionnaire de 24 mois a plus de questions sur les objets que les questionnaires de 12 mois et de 36 mois, ce qui peut expliquer les taux plus élevés de scores anormaux. Le dépistage développemental avec le ASQ-3 pourrait s'avérer ne pas capturer de manière adéquate les compétences des enfants dans des communautés similaires.

Targeted nonviral gene-based inhibition of Gα(i/o)-mediated vagal signaling in the posterior left atrium decreases vagal-induced atrial fibrillation.

BACKGROUND: Pharmacologic and ablative therapies for atrial fibrillation (AF) have suboptimal efficacy. Newer gene-based approaches that target specific mechanisms underlying AF are likely to be more efficacious in treating AF. Parasympathetic signaling appears to be an important contributor to AF substrate. OBJECTIVE: The purpose of this study was to develop a nonviral gene-based strategy to selectively inhibit vagal signaling in the left atrium and thereby suppress vagal-induced AF. METHODS: In eight dogs, plasmid DNA vectors (minigenes) expressing Gα(i) C-terminal peptide (Gα(i)ctp) was injected in the posterior left atrium either alone or in combination with minigene expressing Gα(o)ctp, followed by electroporation. In five control dogs, minigene expressing scrambled peptide (Gα(R)ctp) was injected. Vagal- and carbachol-induced left atrial effective refractory periods (ERPs), AF inducibility, and Gα(i/o)ctp expression were assessed 3 days following minigene delivery. RESULTS: Vagal stimulation- and carbachol-induced effective refractory period shortening and AF inducibility were significantly attenuated in atria receiving a Gα(i2)ctp-expressing minigene and were nearly eliminated in atria receiving both Gα(i2)ctp- and Gα(o1)ctp-expressing minigenes. CONCLUSION: Inhibition of both G(i) and G(o) proteins is necessary to abrogate vagal-induced AF in the left atrium and can be achieved via constitutive expression of Gα(i/o)ctps expressed by nonviral plasmid vectors delivered to the posterior left atrium.
