RESUMO

Domain-general prediction differences have been posited as underlying many aspects of the cognitive-behavioral profile in autism. An interesting potential implication of such differences is hyperplasticity of learning-the idea that autistic individuals may privilege more recent input over the accumulation of prior learning. Because real world language input is highly variable, hyperplasticity could have serious ramifications for language learning. To investigate potential hyperplasticity during a language processing task, we administered an experimental anticipatory eye movement (AEM) task to 2- to 3-year-old autistic children and neurotypical (NT) peers. Autistic children's change in anticipation from before to after a switch in contingencies did not significantly differ from NT counterparts, failing to support claims of hyperplasticity in the linguistic domain. Analysis of individual differences among autistic children revealed that cognitive ability was associated with prediction of the initial, stable contingencies, but neither age nor receptive language related to task performance. Results are discussed in terms of clinical implications and the broader context of research investigating prediction differences in autism.

RESUMO

Searches for autism on social media have soared, making it a top topic. Social media posts convey not only plain text, but also sentiments and emotions that provide insight into the experiences of the autism community. While sentiment analysis categorizes overall sentiment, emotion analysis provides nuanced insights into specific emotional states. The objective of this study is to identify emotions in posts related to autism and compare the emotions specifically contained in posts that include the hashtag #ActuallyAutistic with those that do not. METHODS: We extracted a sample of X' posts related to autism and used DistilBERT to assign one out of six emotions (sadness, joy, love, anger, fear, surprise) to each post. RESULTS: We have analyzed a total of 414,287 posts, 98,602 (23.8%) of those included the hashtag #ActuallyAutistic. The most common expressed emotion was joy, which was expressed in 52.5% of the posts, followed by sadness, identified in 28.6% of the posts. 12% of the posts expressed fear, 4.9% reflected anger, 1.1% showed love, and 0.9% expressed surprise. Posts tagged as #ActuallyAutistic showed less joy (27.1% vs. 60.4% in posts without this hashtag, p<0.001) and more sadness (52.7% vs. 21.1% in those without the hashtag, p<0.001). CONCLUSIONS: The use of the hashtag #ActuallyAutistic is associated with a different emotional tone, characterized by less joy and more sadness. These results suggest the need for greater support and acceptance towards the autistic community, both online and in society in general. Insights from our study can be valuable for policy makers, health, educational or other programmes aiming at enhancing well-being, inclusiveness, improve services, and create a more compassionate and understanding atmosphere for autistic people.

RESUMO

Background: Gestational nutrition can protect against adverse neurodevelopmental outcomes. Objectives: We developed a short tool for collecting maternal nutritional intake during pregnancy to facilitate research in this area and compared its retrospective use to prospectively-collected food frequency questionnaires (FFQ). Methods: Maternal nutritional intake was retrospectively assessed using three versions (full interview, full self-administered online, and shortened interview) of the Early Life Exposure Assessment Tool (ELEAT) among participants of the MARBLES pregnancy cohort study of younger siblings of autistic children. Retrospective responses were compared with responses to supplement questions and the validated 2005 Block FFQ prospectively collected in MARBLES during pregnancies 2-7 years prior. ELEAT nutrient values were calculated using reported food intake frequencies and nutrient values from the USDA nutrient database. Correlations between retrospectively- and prospectively-reported intake were evaluated using Kappa coefficients, Youden's J, and Spearman Rank Correlation Coefficients (rs). Results: MARBLES FFQ dietary intakes were compared among 54 women who completed the ELEAT full form including 12 online, and among 23 who completed the ELEAT short form. Correlations across most foods were fair to moderate. Most ELEAT quantified nutrient values were moderately correlated (rs = 0.3-0.6) with those on the Block FFQ. Supplement questions in both MARBLES and the ELEAT were completed by 114 women. Kappas were moderate for whether or not supplements were taken, but modest for timing. Correlations varied by version and child diagnosis or concerns, and were higher when mothers completed the ELEAT when their child was 4 years old or younger. Conclusions: With recall up to several years, ELEAT dietary and supplement module responses were modestly to moderately reliable and produced nutrient values moderately correlated with prospectively-collected measures. The ELEAT dietary and vitamin supplements modules can be used to rank participants in terms of intake of several nutrients relevant for neurodevelopment.

RESUMO

Background: Often, the indirect impact of autism spectrum disorder (ASD) presents the family with significant challenges. One of these challenges is affiliate stigma due to parental affiliation with their child. This study aimed to explore affiliate stigma, resilience and quality of life (QoL) among parents of children with ASD. Methods: Cross-sectional study of 144 parents of children with ASD were recruited from two main tertiary hospitals in Kelantan, Malaysia, a developing country in Southeast Asia. Pearson correlation was used to examine the relationship between parental affiliate stigma, resilience and QoL. Simple and multiple linear regression analyses were used to identify the significant associated factors of affiliate stigma, resilience and QoL. Results: Correlational analyses revealed that perceived affiliate stigma demonstrated an inverse relationship with resilience and QoL. Additionally, resilience had a positive relationship with QoL. Regression analyses revealed that the father's employment status, the mother's level of education, having a disability card, the child's age at ASD diagnosis, comorbidities of the child and ASD severity perceived by parents were associated with parental affiliate stigma, resilience and QoL. Conclusion: Study findings highlight the contribution of socio-demographic characteristics of children with ASD and their families in the determination of affiliate stigma, resilience and QoL.

RESUMO

BACKGROUND: ADHD and autism are common and increasing neurodevelopmental disorders in the world and also occur among nurses. However, almost nothing is known about nurses with these diagnoses. To promote high-quality care provision and well-being in the nursing workforce, it is important to discover more about these nurses. Therefore, in the present study, we aimed to describe how nurses with ADHD and/or autism experience their working life. METHODS: The study was descriptive in design. Nurses were invited via Swedish Facebook groups targeting nurses. Semi-structured individual interviews were conducted with 17 nurses with ADHD and/or autism, online or by telephone. Data were analyzed using qualitative content analysis. RESULTS: One overarching theme and seven subthemes emerged from the analysis. The theme "feeling like an untapped resource" reflected the subthemes: 1) Being passionate about one's job, 2) having strengths and talents to use in working life, 3) a stressful and disturbing work environment inhibits personal strengths, 4) managers show goodwill but lack knowledge and resources, 5) feeling appreciated but socially different among colleagues, 6) using a variety of strategies to facilitate working life and 7) toward an uncertain future. CONCLUSION: Nurses with ADHD and/or autism experience having abilities and talents that are useful in the nursing profession. However, they feel that the physical and organizational working conditions and lack of managerial support entail challenges that prevent them from making optimal use of their strengths.

RESUMO

BACKGROUND: There is evidence suggesting that autistic traits are associated with schizotypal traits. This study examined the factor structure of the Autism Spectrum Quotient 10 (AQ-10) and its associations with schizotypal traits (measured by the Schizotypal Personality Questionnaire-Brief [SPQ-B]) in a cohort of Chinese adolescents and young adults. METHODS: Invitation letters, stratified by locations and housing types, were randomly sent to individuals aged 15 to 24 years for participation. Assessments were made using face-to-face or online interviews. Autistic traits were assessed using the Chinese version of the AQ-10. Schizotypal personality traits were assessed using the Chinese version of the 22-item SPQ-B. RESULTS: In total, 395 male and 536 female participants (mean age, 19.93 years) were recruited between July 2020 and May 2021. Exploratory factor analysis of the AQ-10 yielded three factors (theory of mind, task switching, and attention deficits) explaining 55.11% of the total variance. Autistic traits were positively correlated with schizotypal traits of disorganised features (r = 0.21, p < 0.001), interpersonal relationship deficits (r = 0.19, p < 0.001), and cognitive-perceptual deficits (r = 0.11, p = 0.001). CONCLUSION: In Chinese adolescents and young adults, autistic traits, especially task switching and attention deficits (compared with theory of mind) are more closely correlated with schizotypal personality traits. Disentangling the overlapping and diametrical structure of autistic traits and schizotypal traits may help understand their aetiologies, assessment, and interventions.

RESUMO

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition that impairs communication, socialization, and behavior. The association of ASD with folic acid has been investigated due to the importance of this vitamin for neurological health. This study is an update of the publication 'Folic acid and autism: What do we know?' and aims to systematically review studies examining the relationship between folic acid and ASD. The search resulted in 2,389 studies on folic acid and ASD, which were selected by two reviewers based on their titles and abstracts. Studies meeting the inclusion criteria were fully read. The 52 included studies involved 10,429 individuals diagnosed with ASD and assessed the intake of vitamin B6, folic acid, and vitamin B12; serum levels of these vitamins, homocysteine, and methionine; therapeutic interventions using folic acid; and the association between maternal exposure to this vitamin and the risk of ASD. The evidence of insufficient folic acid intake in most individuals with ASD remains consistent in this update. No association was found between maternal exposure to folic acid and the risk of ASD in their children. Despite observed improvements in communication, socialization, and behavior in individuals with ASD following folic acid interventions, it is crucial to consider the individuality and complexity of ASD. Given the relevance of the topic, there remains a need for more high-quality research and clinical trials characterized by rigorous methodological designs.

RESUMO

Background: Given the rising interest in complementary therapeutic strategies for autism spectrum disorder (ASD), this research aims to provide a comprehensive analysis of the impact of animal-assisted activities and therapies (AAAT) on various ASD symptoms. Methods: A meticulous search of databases, including Scopus and PubMed, was conducted to gather relevant research on AAAT for ASD. This process led to the selection of 45 studies encompassing 1,212 participants. The chosen studies were then subjected to a meta-analysis to evaluate the efficacy of AAAT in alleviating core ASD symptoms. Results: The meta-analysis revealed significant improvements in several core ASD symptoms due to AAAT. Notably, there were improvements in social communication (MD = -4.96, 95% CI [-7.49, -2.44]), irritability (MD = -2.38, 95% CI [-4.06, -0.71]), hyperactivity (MD = -4.03, 95% CI [-6.17, -1.89]), and different word usage skills (MD = 20.48, 95% CI [7.41, 33.55]). However, social awareness (MD = -1.63, 95% CI [-4.07, 0.81]), social cognition (MD = -3.60, 95% CI [-9.36, 2.17]), social mannerisms (MD = -0.73, 95% CI [-2.55, 1.09]), social motivation (MD = -1.21, 95% CI [-2.56, 0.13]), lethargy (MD = -1.12, 95% CI [-3.92, 1.68]), and stereotypical behaviors (MD = -0.23, 95% CI [-1.27, 0.80]) did not significantly improve. Conclusion: The study demonstrates the potential of AAAT in improving certain core symptoms of ASD, such as social communication, irritability, hyperactivity, and word usage skills. However, the effectiveness of AAAT in other ASD symptom domains remains uncertain. The research is limited by the absence of long-term follow-up data and a high risk of bias in existing studies. Therefore, while the findings indicate the promise of AAAT in specific areas, caution is advised in generalizing its efficacy across all ASD symptoms.

RESUMO

Introduction: Autism is a neurodevelopmental condition that is increasing in prevalence worldwide. There has been an exponential increase in autism-related research since 2010, when the first Singapore Clinical Practice Guidelines (CPG) on autism was published. Understanding of autism has since evolved to adopt a lifespan approach beyond that of a childhood condition. The aim of this CPG was to provide an updated set of recommendations for children and adolescents to aid clinical practice for professionals. Method: A multidisciplinary workgroup that comprised representatives from various sectors worked on this CPG. Clinical questions were organised into 10 different sections, each with its own subgroup of members. Seventeen existing international guidelines were evaluated using the Appraisal of Guidelines for REsearch & Evaluation II (AGREE-II) framework, of which 4 met criteria to act as references. Literature review across multiple databases was conducted between January 2011 to 2023; Grading of Recommendations, Assessment, Development and Evaluation (GRADE-like) methodology was used to synthesise evidence. Recommendation statements were derived, following Delphi-style consensus surveys among the workgroup. The draft guidelines underwent external review and public consultation before being formalised. Results: Recommendation and good practice statements pertaining to care of children and adolescents on the autism spectrum across 10 different sections were developed. Evidence matrices complement these recommendations and detail relevant evidence behind each recommendation statement. Conclusion: It is intended for these guidelines to promote effective management and healthcare services for children and adolescents on the autism spectrum, by reinforcing good and evidence-based clinical practice within our national context.

RESUMO

AIM AND OBJECTIVE: The purpose of the study is to determine the neuroprotective effect of capric acid on sodium valproate-induced model of autism. METHODS: In this study, the effect of CA was observed in animals with single dose of valproic acid (600 mg/kg, i. p.) where the disease condition was confirmed by developmental impairment in pups. Behavioral tests that assess anxiety, depression, stereotypical and repetitive behavior, social interaction, learning and memory, and other confounding variables were performed. Subsequently, oxidative stress parameters, pro-inflammatory cytokine levels and mitochondrial complex activities in the selected brain regions were analyzed. RESULTS: Valproic acid successfully produced autism-like symptoms from post-natal day 7 and also demonstrated impairment in social behavior, learning and memory, and anxiety and depression. Valproic acid was found to produce oxidative stress and neuro-inflammation in the hippocampus, prefrontal cortex, and cerebellum. Treatment with capric acid produced a positive effect on the alterations with maximum effects evident at 400 mg/kg, p. o. through amelioration of behavioral as well as biochemical changes. CONCLUSION: The current study concluded that capric acid could act as a likely candidate for the treatment and management of autism via significant modulation of neurobehavioral parameters, oxidative stress, mitochondrial dysfunction and inflammatory markers.

RESUMO

BACKGROUND: Instrumented measurements of postural control provide a more accurate insight into the motor development of children with autism. This study aimed to identify postural control deficits in autistic children during quiet standing before and after transient locomotor task. It was hypothesized that the parameters that characterize the trajectory of center of foot pressure (COP) displacement would be higher in autistic children compared to typically developing children. METHODS: Sixteen autistic children aged 6-10 but without a comorbidity diagnosis, were enrolled in the study group. The control group comprised 16 typically developing peers. The assessment of the transitional task comprised four different conditions: unperturbed and perturbed transition, stepping up, and stepping down tasks. Analysis of the COP signal was carried out for three distinct phases, i.e., phase 1 - quiet standing before step initiation, phase 2 - transit, and phase 3 - quiet standing until measurement completion. FINDINGS: The two-way ANOVA with a 2 × 4 factorial design (group × testing condition) revealed a group effect on all posturographic variables in the antero-posterior and medio-lateral directions of phase 1 and in the antero-posterior direction of phase 3. The Bonferroni post-hoc test showed the means of all those variables were significantly higher for the autistic than for typically developing children. Group allocation also had an effect on the time of transit and step length, which turned out to be significantly longer in autistic children compared to healthy peers. INTERPRETATION: Autistic children show increased postural sway before and after transitional locomotor tasks compared to typically developing children. The trial was prospectively registered in the Australian and New Zealand Clinical Trials Registry (no. ACTRN12621001113842; date registered: 23.08.2021).

RESUMO

OBJECTIVE: To evaluate associations between change in weight z score after neonatal intensive care unit (NICU) discharge and neurodevelopmental outcomes and obesity at 12-48 months of age among individuals born very preterm. STUDY DESIGN: This secondary analysis used data from infants born very preterm participating in the Environmental influences on Child Health Outcomes cohort (n = 1400). Growth during infancy was calculated as change in weight z score between NICU discharge and follow-up at a mean of 27 months of age. Very low weight gain was defined as a change in weight z score <-1.67; very high weight gain was a change in weight z score >1.67. Neurodevelopmental outcomes included the Bayley Scales of Infant and Toddler Development, Child Behavior Checklist 1.5-5 years, and Modified Checklist for Autism in Toddlers. Multivariable linear regression was used to estimate associations between increase in weight z score and neurodevelopmental outcomes. RESULTS: Very low weight gain between NICU discharge and follow-up (experienced by 6.4% of participants) was associated with lower scores on cognitive (adjusted mean difference: -4.26; 95% CI: -8.55, -0.04) and language (adjusted mean difference: -4.80; 95% CI: -9.70, -0.11) assessments. Very high weight gain (experienced by 13.6% of participants) was associated with an increased obesity risk (adjusted relative risk: 6.20; 95% CI: 3.99, 9.66) but not with neurodevelopmental outcomes. CONCLUSIONS: Very high weight gain in the first 12-48 months after NICU discharge was associated with a higher risk of obesity at follow-up; very low weight gain was associated with lower scores on cognitive and language assessments.

RESUMO

Autism spectrum disorder (ASD) is expressed with neurobehavioral symptoms of different degrees of intensity. It is estimated that, for every three cases detected, there are two cases that reach adulthood without treatment. Objective: To establish what challenges are still present in the implementation of early intervention (EI) and its effects on the prognosis of ASD. Methods: A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (Prisma) methodology was carried out in the PubMed and ScienceDirect databases in January 2023. The search keywords were "autism spectrum disorder", "early intervention" and "prognosis". Results: Sixteen studies were included, two randomized and 14 non-randomized. Knowledge about the signs of ASD, diagnostic and therapeutic methods, age at the start of treatment, and socioeconomic factors were the main challenges encountered in the implementation of the EI. Conclusion: EI is capable of modifying the prognosis of ASD and challenges in its implementation persist, especially in developing regions with low socioeconomic status.


O transtorno do espectro autista (TEA) expressa-se com sintomas neurocomportamentais de diferentes graus de intensidade. Estima-se que, para cada três casos detectados, existam dois casos que atingem a idade adulta sem tratamento. Objetivo: Estabelecer quais são os desafios ainda presentes na implementação efetiva da intervenção precoce (IP) e quais são os seus efeitos no prognóstico do TEA. Métodos: Revisão sistemática com a metodologia Preferred Reporting Items for Systematic Reviews and Meta-Analyses (Prisma) foi realizada nos bancos de dados PubMed e ScienceDirect em janeiro de 2023. As palavras-chave da pesquisa foram "autism spectrum disorder", "early intervention" e "prognosis". Resultados: Dezesseis estudos foram incluídos, sendo dois randomizados e 14 não randomizados. O conhecimento sobre os sinais do TEA, os métodos diagnósticos e terapêuticos, a idade de início de tratamento e os fatores socioeconômicos foram os principais desafios encontrados na implementação da IP. Conclusão: A IP é capaz de modificar o prognóstico do TEA e os desafios em sua implementação ainda afetam, principalmente, regiões em desenvolvimento e de baixo status socioeconômico.

RESUMO

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by social, behavioral, and learning challenges. Individuals with autism and their families often struggle to get an appropriate diagnosis and continuation of specialty services, including general healthcare, mental health and transition services, special education, employment, and social and emotional support. This paper presents information about the current policies and support mechanisms that exist to help these individuals and their families. This paper identifies the gaps and recommends areas of improvement based on evidence-based research and current data. ASD is a lifelong disability without a cure, but by constructing robust policies and providing enhanced support, the quality of lives of those with ASD and their families can be improved.

RESUMO

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.

RESUMO

Although multiple theories have speculated about the brainstem reticular formation's involvement in autistic behaviors, the in vivo imaging of brainstem nuclei needed to test these theories has proven technologically challenging. Using methods to improve brainstem imaging in children, this study set out to elucidate the role of the autonomic, nociceptive, and limbic brainstem nuclei in the autism features of 145 children (74 autistic children, 6.0-10.9 years). Participants completed an assessment of core autism features and diffusion- and T1-weighted imaging optimized to improve brainstem images. After data reduction via principal component analysis, correlational analyses examined associations among autism features and the microstructural properties of brainstem clusters. Independent replication was performed in 43 adolescents (24 autistic, 13.0-17.9 years). We found specific nuclei, most robustly the parvicellular reticular formation-alpha (PCRtA) and to a lesser degree the lateral parabrachial nucleus (LPB) and ventral tegmental parabrachial pigmented complex (VTA-PBP), to be associated with autism features. The PCRtA and some of the LPB associations were independently found in the replication sample, but the VTA-PBP associations were not. Consistent with theoretical perspectives, the findings suggest that individual differences in pontine reticular formation nuclei contribute to the prominence of autistic features. Specifically, the PCRtA, a nucleus involved in mastication, digestion, and cardio-respiration in animal models, was associated with social communication in children, while the LPB, a pain-network nucleus, was associated with repetitive behaviors. These findings highlight the contributions of key autonomic brainstem nuclei to the expression of core autism features.

RESUMO

INTRODUCTION: Autism spectrum disorder (ASD) is an early-onset disorder with a prevalence of 1% among children and reported disability-adjusted life years of 4.31 million. Irritability is a challenging behavior associated with ASD, for which medication development has lagged. More specifically, pharmacotherapy effectiveness may be limited against high adverse effects (considering side effect profiles and patient medication sensitivity); thus, the possible benefits of pharmacological interventions must be balanced against potential adverse events in each patient. AREAS COVERED: After reviewing the neuropathophysiology of ASD-associated irritability, the benefits and tolerability of emerging medications in its treatment based on randomized controlled trials were detailed in light of mechanisms and targets of action. EXPERT OPINION: Succeeding risperidone and aripiprazole, monotherapy with memantine may be beneficial. In addition, N-acetylcysteine, galantamine, sulforaphane, celecoxib, palmitoylethanolamide, pentoxifylline, simvastatin, minocycline, amantadine, pregnenolone, prednisolone, riluzole, propentofylline, pioglitazone, and topiramate, all adjunct to risperidone, and clonidine and methylphenidate outperformed placebo. These effects were through glutamatergic, γ-aminobutyric acidergic, inflammatory, oxidative, cholinergic, dopaminergic, and serotonergic systems. All medications were reported to be safe and tolerable. Considering sample size, follow-up, and effect size, further studies are necessary. Along with drug development, repositioning and combining existing drugs supported by the mechanism of action is recommended.

RESUMO

Autism spectrum disorder (ASD) represents a panel of conditions that begin during the developmental period and result in impairments of personal, social, academic, or occupational functioning. Early diagnosis is directly related to a better prognosis. Unfortunately, the diagnosis of ASD requires a long and exhausting subjective process. We aimed to review the state of the art for automated autism diagnosis and recognition in this research. In February 2022, we searched multiple databases and sources of gray literature for eligible studies. We used an adapted version of the QUADAS-2 tool to assess the risk of bias in the studies. A brief report of the methods and results of each study is presented. Data were synthesized for each modality separately using the Split Component Synthesis (SCS) method. We assessed heterogeneity using the I 2 statistics and evaluated publication bias using trim and fill tests combined with ln DOR. Confidence in cumulative evidence was assessed using the GRADE approach for diagnostic studies. We included 344 studies from 186,020 participants (51,129 are estimated to be unique) for nine different modalities in this review, from which 232 reported sufficient data for meta-analysis. The area under the curve was in the range of 0.71-0.90 for all the modalities. The studies on EEG data provided the best accuracy, with the area under the curve ranging between 0.85 and 0.93. We found that the literature is rife with bias and methodological/reporting flaws. Recommendations are provided for future research to provide better studies and fill in the current knowledge gaps.

RESUMO

Background. Many caregivers of autistic children experience increased stress, and diminished health often due to the caregiving demands. Purpose. The project aim was to design a feasible and sustainable wellness program tailored to these caregivers' lives. Methods. In this collaborative research-informed project, participants (N = 28) were mostly female, white, and well-educated. In focus groups, we delineated lifestyle issues, then designed, delivered and assessed an initial program with one cohort; and repeated this process with a second group. Findings. Focus group data were transcribed then coded qualitatively to inform following steps. Data analysis identified lifestyle issues key to program design, desired program elements, and after program delivery, affirmed elements and recommended changes. The team used meta-inferences to guide program revisions after each cohort. Implications. Caregivers viewed resulting 5Minutes4Myself program as filling a significant service gap; its hybrid design used in-person coaching and a habit-building app with mindfulness content to support lifestyle change.

RESUMO

BACKGROUND: Children with autism spectrum disorder (ASD) face unique challenges related to oral health, which can negatively impact their day-to-day lives, significantly compromising their overall quality of life. Primary caregivers of children with ASD have a critical role in delivering and seeking oral health care. Hence, it is vital to study their perspective towards their children's oral health and its impact on their quality of life. AIM: To explore the parental perception of oral health-related quality of life in children with autism. METHODS: A systematic electronic and manual search was conducted in Medline (via PubMed), Embase, Google Scholar, Scopus, and LILACS of articles published from January 2003 to May 2023 using appropriate MeSH terms, keywords, and other terms. A four-phase study selection process was followed according to PRISMA guidelines, and data extraction and synthesis were performed using an extraction form. The selected studies were critically appraised using the QATSDD and Crombie's assessment tool. The inter-reviewer agreement was assessed using the kappa with a linear weighting coefficient. RESULTS: Out of the 885 results, 15 studies were included in the review after the two selection phases, and the study characteristics were summarized in tabular form. Study quality varied considerably, and out of a total possible QATSDD score of 42, scores for the individual studies ranged from 14 to 40. The risk of bias for the seven criteria was found to be low. CONCLUSION: The parental perception of the OHRQoL in children with ASD is poor, and the most significant perceived impact is on the child's functional and social well-being aspects. Parental-Caregiver Perception Questionnaire was the most commonly used. The most frequent symptoms include bad breath, food lodgment, mouth breathing and night grinding. The familial impact and influence on the OHRQoL of siblings were also studied.
