Clinical presentation and spectrum of gluten symptomatology in celiac disease.

Views on the clinical presentation and symptomatology of celiac disease have evolved alongside advances in disease detection and understanding of disease pathogenesis. While historically regarded a pediatric illness characterized by malabsorption, it is now better viewed as an immune illness of gluten-specific T cells with systemic manifestations affecting all ages. Its broad presentation, including frequent extraintestinal manifestations and asymptomatic disease, contributes to suboptimal disease detection. Adverse symptoms greatly impact patient quality of life and can result from chronic gluten exposure in untreated disease or those poorly responsive to the gluten free diet and can also present as acute symptoms after episodic gluten exposure. Functional gastrointestinal disease is a common comorbidity. Biomarkers like interleukin-2 that are highly sensitive and specific for celiac disease highlight a role for gluten-specific T cells in acute gluten symptomatology. A mechanistic understanding of symptoms will inform approaches to better measure and effectively treat them.

Brief Report: Single-Session Interventions for Mental Health Challenges in Autistic People: An (Almost) Empty Systematic Review.

Single-session interventions (specific, structured programs that intentionally involve just one visit or encounter with a clinic, provider, or program) have been proven to prevent or reduce mental health challenges and reduce barriers to access. This review aimed to identify and synthesise literature on the acceptability, feasibility, effectiveness, or efficacy of (non-pharmacological) single-session interventions for autistic people. Four databases (Scopus, MEDLINE, PsycINFO, and ProQuest) were searched in 12.7.2023, with no date restrictions. Search terms were selected to identify articles reporting on single-session interventions in autistic people. Two raters screened titles/abstracts of 286 articles and full text of 17 articles, resulting in just two included articles, reporting on 46 participants. Risk of bias was assessed with the Quality Assessment with Diverse Studies (QuADS). The two included papers report on specific techniques taught within a single visit to a clinic using pre- and immediate post-intervention questionnaires. One study also reported on cortisol levels pre and post. Neither study reported on acceptability or feasibility of single-session interventions. However, there was insufficient quality evidence to evaluate the effectiveness or efficacy of single-session interventions for autistic people. Although there is substantial research on single-session interventions in the broader population, there is a lack of research into such approaches for autistic people. This is a missed opportunity to evaluate a potential means of support for those at elevated risk of mental health challenges and unmet mental health service need. Future research should co-produce and co-evaluate such approaches as a priority.

Parenting Practices and Externalizing Behaviors in Autistic Children: A Systematic Literature Review.

There is limited recent research on the association between parenting practices and externalizing behaviors in autistic children. To address this gap, the current systematic review examined the associations between parenting practices and externalizing behaviors in autistic children, along with the mediating and moderating effects of parent and child variables (PROSPERO registration number CRD42022268667). Study inclusion criteria were (1) Peer-reviewed journals, (2) Participants included parents of autistic children and their children, (3) Quantitative measures of both parenting practices or behaviors/style and child externalizing behaviors, (4) Cross-sectional or longitudinal studies only, and (5) Studies published in English. Study exclusion criteria were: (1) Qualitative studies, (2) Published in a language other than English, (3) Participants included non-human participants, (4) Participants that did not include parents and their autistic children as participants or did not report this group separately, (5) Systematic review and meta-analyses, and (6) No quantitative measures of parenting practices and/or child externalizing behaviors. Quality appraisal and risk of bias were conducted using the McMaster Tool and results were synthesized in Covidence and Excel. Thirty studies were included in the review. Results demonstrated that mindful parenting was associated with fewer or lower levels of externalizing behaviors; positive parenting practices had non-significant associations with externalizing behaviors; specific parenting practices had differing associations with externalizing behaviors; and negative parenting practices were associated with higher levels of externalizing behaviors. We are unable to draw causal relationships due to focus on cross-sectional and longitudinal articles only. The potential for future research to target specific parent practices to support children's externalizing behaviors is discussed.

Using Q-sort method to explore autistic students' views of the impacts of their anxiety at school.

LAY ABSTRACT: Many autistic students experience anxiety, but there is little research that explores how anxiety might affect autistic students in the school environment. In this study, 45 autistic students, aged 7 to 17 years, completed an online sorting activity to tell us how anxiety impacts them at school. The students were given 21 statements about possible social and academic effects of anxiety (for example, 'When I'm worried it's hard to start my schoolwork' or 'When I'm worried I talk less to my friends or other students'), and sorted them based on how much they agreed each statement was true for them. The three statements most highly rated as being impacted by anxiety were difficulties related to schoolwork. By comparing the information provided by students, six smaller groups of students were identified who sorted the statements in a similar order. These groups show that anxiety affects different autistic students in different ways, including missing school or activities, communicating less with friends and teachers and finding it harder to complete schoolwork. This online sorting activity enabled autistic students themselves to report how anxiety affects them at school. The results suggest that it is important to provide individualised support for autistic students who experience anxiety at school, to reduce the impact of their anxiety on their participation, communication and interactions, and schoolwork. Further research about the effects of anxiety on the academic outcomes of autistic students is also needed.

Letter to the Editor: A possible threat to data integrity for online qualitative autism research.

LAY ABSTRACT: Doing research online, via Zoom, Teams, or live chat, is becoming more and more common. It can help researchers to reach more people, including from different parts of the world. It can also make the research more accessible for participants, especially those with different communication preferences. However, online research can have its downsides too. We have recently been involved in three studies in which we had in-depth discussions with autistic people and/or parents of autistic children about various topics. It turns out, though, that some of these participants were not genuine. Instead, we believe they were "scammer participants": people posing as autistic people or parents of autistic children, possibly to gain money from doing the research. This is a real problem because we need research data that we can trust. In this letter, we encourage autism researchers to be wary of scammer participants in their own research.

Profiles and Longitudinal Growth Trajectories of Teacher-Rated Academic Skills and Enablers in Autistic Children and Adolescents.

In non-autistic children, academic skills are associated with academic enablers (motivation, engagement, study/interpersonal skills), but few studies have explored these in autistic children. This study identified profiles of academic skills and enablers in autistic students and explored the trajectory of each profile over time. Teachers completed the Academic Competences Evaluation Scales for autistic children in primary and secondary educational settings annually for 5 years. Latent profile analysis identified six profiles in the primary/younger cohort and seven in the secondary/older cohort. Whilst some profiles showed relative stability across skills and enablers, others profiles were more variable. The profiles remained stable and significantly different from each other over time, with no profile × time interactions identified. Autistic children may show variability across their academic skills and enablers. This highlights the importance of understanding each individual student and their profile of strengths and challenges when planning supports.

Parent-reported environmental factors and strategies to support home and community participation in children on the autism spectrum.

PURPOSE: Participating in home and community activities can be influenced by environmental factors and parent strategies. Children on the autism spectrum are reported to participate less in home and community activities than their neurotypical peers. Little is known about environmental factors that may influence their participation, and ways parents support their child's participation. MATERIALS AND METHODS: Parents of children on the autism spectrum aged 5-6 years (n = 72) and 10-11 years (n = 94) completed the Participation and Environment Measure for Children and Youth. This study reports on the perceived support, barriers, and resources in the home and the community environment. Parents reported strategies they used to support their child's participation in home and the community. RESULTS: Home environmental factors were identified as more supportive by the parents of younger children. The sensory quality of activities and social demands were factors identified as making community participation harder for both groups. Parents used a range of different strategies in the home and the community to support their child's participation. CONCLUSIONS: Identifying environmental barriers and supports to participation can assist in developing interventions to support meaningful participation in activities for children on the autism spectrum.Implications for rehabilitationSkills required for the activity and preferences of children on the autism spectrum are important considerations when supporting their participation in activities.When exploring a child's level of participation, it may be helpful to ask parents about what their child can do with or without their support.The sensory quality of the environment is a consideration when supporting the participation of children on the autism spectrum in community activities.As sensory processing is an individual experience, the impact of sensory elements of the environment may differ for individuals.

The relationshipbetween anxiety and social outcomes in autistic children and adolescents: A meta-analysis.

Anxiety is one of the most frequently reported co-occurring conditions for autistic children and adolescents. The relationship between anxiety and social outcomes in autistic youth has been the focus of a range of studies, with mixed results. This meta-analysis aimed to identify the strength of the association between anxiety and a frequently researched social outcome (social competence) in autistic young people and whether that association is influenced by individual or research design factors. A previous preregistered systematic review was updated with a search of the same three databases (CINAHL, ERIC, and PsycINFO) as the original review. Through this, 20 studies with sufficient data on a neurotypically-defined measure of social competence and anxiety were identified. Results were synthesised using a mixed effects model. The meta-analysis on 2,321 participants (from 22 samples) highlighted wide heterogeneity in results. The findings show that anxiety has a significant, small negative impact on social competence (d = - 0.48; 95% CI = - 0.71, - 0.26), meaning that as scores on measures of anxiety increase, scores on measures of social competence decrease. This relationship between anxiety and social competence was moderated by age, becoming weaker as age increased. Whilst this is an important finding for supporting mental health and well-being of autistic young people, the large amount of variance left unexplained suggests that multiple factors, including the use of measures designed for neurotypical people and the potential impact of camouflaging on such measures, need to be considered in future designs.

Longitudinal studies of challenging behaviours in autistic children and adults: A systematic review and meta-analysis.

Autistic children and adults are at increased risk of showing behaviours that may be described as challenging, however, little is known about whether or how these behaviours may change over time. Given the profound impact that challenging behaviour can have on both the autistic individual and their support network, it is critical that the trajectory of challenging behaviours be better understood. This systematic review and meta-analysis identified and synthesised observational longitudinal studies of challenging behaviour in autistic individuals. Fifty-six studies were included in the systematic review, and the effect sizes of 37 independent samples arising from 34 of these reports were examined through meta-analysis. Crucially, across the 37 samples, scores on the measures of challenging behaviour reduced by a small, yet significant, extent over time. Although age of the sample at baseline assessment did not moderate the effect, the time between the baseline assessment and final follow-up and age at final follow-up both moderated the magnitude of the effect, with challenging behaviour scores reducing to a larger extent in (a) studies with longer intervals between baseline and final follow-up and (b) studies with older samples at follow-up. The results from the current systematic review and meta-analysis have both theoretical and practical implications for understanding challenging behaviour over time in autistic individuals. Avenues for future research are also highlighted that may allow better understanding, and therefore support of, challenging behaviour in autistic individuals.

A Parent-Mediated Anxiety Intervention Specifically Tailored for Autistic Preschoolers: A Pilot Study.

IMPORTANCE: Autistic children experience reduced participation in life activities. One factor that may contribute to their reduced levels of participation is anxiety, which is identified at higher rates among young autistic children than among their neurotypical peers. Anxiety is also strongly associated with sensory overresponsivity and has a considerable impact on daily functioning. OBJECTIVE: To determine the feasibility, acceptability, and usefulness of a small-group, parent-mediated intervention to prevent and reduce anxiety. DESIGN: Pre-post. SETTING: University research center. PARTICIPANTS: Three parents of autistic children (ages 4-7 yr). OUTCOMES AND MEASURES: Parents completed a six-session group training program. Parents completed an anxiety scale for their child before and after parent training. At the end of training, parents participated in a focus group and were interviewed 4 mo after training. RESULTS: Positively received aspects of the intervention were the benefits of a small group, composed of parents of autistic children, run by a facilitator with expertise in autism and anxiety. Parents gained knowledge, resulting in "taking a different approach" with their child and "seeing an interplay between anxiety and autism." After the intervention, parents reported a reduction in children's reported anxiety levels. CONCLUSIONS AND RELEVANCE: Knowledge of autism and anxiety acquired during a parent-mediated group increased parents' understanding of their child's behaviors and assisted them in supporting their child's participation. Further research, including larger studies, is required to determine the effectiveness of this intervention. What This Article Adds: The findings from this research provide preliminary support for the adaptation of an existing parent intervention (Cool Little Kids) to reduce anxiety among autistic children. Parents reported an increased awareness and understanding of anxiety and of the interplay between anxiety and autistic traits. Positionality Statement: This article uses the identity-first language autistic people. This nonableist language describes their strengths and abilities and is a conscious decision. This language is favored by autistic communities and self-advocates and has been adopted by health care professionals and researchers (Bottema-Beutel et al., 2021; Kenny et al., 2016).

On the prediction of premature births in Hispanic labour patients using uterine contractions, heart beat signals and prediction machines.

Preterm birth is a global epidemic affecting millions of mothers across different ethnicities. The cause of the condition remains unknown but has recognised health-based implications, in addition to financial and economic ones. Machine Learning methods have enabled researchers to combine datasets using uterine contraction signals with various forms of prediction machines to improve awareness of the likelihood of premature births. This work investigates the feasibility of enhancing these prediction methods using physiological signals including uterine contractions, and foetal and maternal heart rate signals, for a population of south American women in active labour. As part of this work, the use of the Linear Series Decomposition Learner (LSDL) was seen to lead to an improvement in the prediction accuracies of all models, which included supervised and unsupervised learning models. The results from the supervised learning models showed high prediction metrics upon the physiological signals being pre-processed by the LSDL for all variations of the physiological signals. The unsupervised learning models showed good metrics for the partitioning of Preterm/Term labour patients from their uterine contraction signals but produced a comparatively lower set of results for the various kinds of heart rate signals investigated.

Profiles of autism characteristics in thirteen genetic syndromes: a machine learning approach.

BACKGROUND: Phenotypic studies have identified distinct patterns of autistic characteristics in genetic syndromes associated with intellectual disability (ID), leading to diagnostic uncertainty and compromised access to autism-related support. Previous research has tended to include small samples and diverse measures, which limits the generalisability of findings. In this study, we generated detailed profiles of autistic characteristics in a large sample of > 1500 individuals with rare genetic syndromes. METHODS: Profiles of autistic characteristics based on the Social Communication Questionnaire (SCQ) scores were generated for thirteen genetic syndrome groups (Angelman n = 154, Cri du Chat n = 75, Cornelia de Lange n = 199, fragile X n = 297, Prader-Willi n = 278, Lowe n = 89, Smith-Magenis n = 54, Down n = 135, Sotos n = 40, Rubinstein-Taybi n = 102, 1p36 deletion n = 41, tuberous sclerosis complex n = 83 and Phelan-McDermid n = 35 syndromes). It was hypothesised that each syndrome group would evidence a degree of specificity in autistic characteristics. To test this hypothesis, a classification algorithm via support vector machine (SVM) learning was applied to scores from over 1500 individuals diagnosed with one of the thirteen genetic syndromes and autistic individuals who did not have a known genetic syndrome (ASD; n = 254). Self-help skills were included as an additional predictor. RESULTS: Genetic syndromes were associated with different but overlapping autism-related profiles, indicated by the substantial accuracy of the entire, multiclass SVM model (55% correctly classified individuals). Syndrome groups such as Angelman, fragile X, Prader-Willi, Rubinstein-Taybi and Cornelia de Lange showed greater phenotypic specificity than groups such as Cri du Chat, Lowe, Smith-Magenis, tuberous sclerosis complex, Sotos and Phelan-McDermid. The inclusion of the ASD reference group and self-help skills did not change the model accuracy. LIMITATIONS: The key limitations of our study include a cross-sectional design, reliance on a screening tool which focuses primarily on social communication skills and imbalanced sample size across syndrome groups. CONCLUSIONS: These findings replicate and extend previous work, demonstrating syndrome-specific profiles of autistic characteristics in people with genetic syndromes compared to autistic individuals without a genetic syndrome. This work calls for greater precision of assessment of autistic characteristics in individuals with genetic syndromes associated with ID.

Brief Report: Covid Restrictions had Positive and Negative Impacts on Schooling for Students on the Autism Spectrum.

The COVID-19 pandemic (2020) resulted in school closures and changes to school delivery. The aim of this study was to explore how these changes impacted on children on the autism spectrum. As part of an online survey, parents (n = 180) of school-aged children (9.3-16.5 years) on the autism spectrum in Australia were asked an open-ended question on how the COVID-19 pandemic had impacted on their child's education experience. Nearly half (48%) of the parents reported only negative impacts, 26% only positive impacts, 12% a mix of positive and negative impacts, and 9% little or no impact. Parents identified that school restrictions impacted on more than their child's learning. These findings highlight areas to consider when supporting autism-friendly learning.

Brief Report: Family Accommodation is Associated with the Impact of Childhood Anxiety in Autism.

Anxiety is commonly experienced by children on the autism spectrum, and can negatively impact their lives. Family accommodation has been linked to the impact of anxiety on the child's life in non-autistic children. This study tested whether the same relationship holds for children on the autism spectrum. A community sample (n = 118) of parents of children on the spectrum completed questionnaires on their child's autism characteristics and severity and impact of their child's anxiety, their own anxiety and family accommodation behaviours. Family accommodation was associated with the impact of child anxiety, over and above anxiety severity of the child and parent. Findings support the involvement of parents in psychosocial support for children on the autism spectrum experiencing anxiety.

Factors and experiences that influence school mobility for autistic students: A systematic review.

BACKGROUND: Autistic students are reported to move schools at a high rate, but little is understood about why this is happening. What is known is that the effects of school mobility can negatively impact both short- and long-term outcomes, particularly the child's learning, behaviours, mental health and school retention. AIMS: The aim of this systematic review was to synthesize the research on factors and experiences which influence the family's decision to move their autistic child to another school. METHODS: A protocol was registered with PROPERO (ID: CRD4202120794). Searches were conducted with ERIC, Scopus and Web of Science and seven studies were identified. RESULTS: The studies focused on three main types of mobility: mainstream-to-mainstream school moves, moving between mainstream and segregated schools, and moving between mainstream and homeschool. Parents' concerns for their child's learning, social experiences and mental health, as well as their own interactions with their child's school, influenced the decision to leave. Whilst there were similarities across the studies for reasons to move, there were also differences based upon the settings between which students moved. CONCLUSION: The findings highlight the need for further research across all school mobility types to better understand the reasons underpinning high rates of school mobility for autistic students.

Joint patient and clinician priority setting to identify 10 key research questions regarding the long-term sequelae of COVID-19.

Given the large numbers of people infected and high rates of ongoing morbidity, research is clearly required to address the needs of adult survivors of COVID-19 living with ongoing symptoms (long COVID). To help direct resource and research efforts, we completed a research prioritisation process incorporating views from adults with ongoing symptoms of COVID-19, carers, clinicians and clinical researchers. The final top 10 research questions were agreed at an independently mediated workshop and included: identifying underlying mechanisms of long COVID, establishing diagnostic tools, understanding trajectory of recovery and evaluating the role of interventions both during the acute and persistent phases of the illness.

Profiles and predictors of thriving in children on the autism spectrum.

BACKGROUND: Thriving is defined as the growth of attributes that mark a flourishing, healthy individual and include Competence, Confidence, Connectedness, Character, Caring and Contribution to self, family, community and civil society. Thriving has been linked to positive youth outcomes in neurotypical children and adolescents but has rarely been explored for individuals on the autism spectrum. METHOD: This study explored the profiles and predictors of parent-reported thriving in 111 school children on the autism spectrum, aged 6 to 14 years. RESULTS: Parents rated children as having relative strengths in the Caring and Connectedness dimensions and relative challenges in the Competence dimension. Stronger thriving outcomes were consistently predicted by stronger socialization scores; however, the other predictors of outcome differed by dimensions. CONCLUSION: The current findings provide insight into the individual and contextual factors that predict thriving in children on the autism spectrum. As research into thriving is in its infancy, more work is needed to understand how child, family and contextual factors relate to thriving in individuals on the autism spectrum to foster positive outcomes.

High-dose vitamin C therapy for symptomatic deficiency in a patient with myasthenia gravis and Crohn's disease.

Vitamin C (ascorbic acid) is an essential water-soluble antioxidant, and deficiency (ie, plasma level <11 µmol/L) can result in scurvy. People at the highest risk for vitamin C deficiency (ie, scurvy) are those with inadequate intake, such as patients with alcohol abuse disorder, malnutrition, psychiatric disorders, restrictive eating habits, and food insecurity, as well as those with malabsorptive syndromes. We present a case of a 26-year-old woman with Crohn's colitis, myasthenia gravis, and juvenile rheumatoid arthritis who presented with frequent bruising, epistaxis, and excessive bleeding from small cuts and who was found to be deficient in vitamin C. Plasma levels initially normalized with oral vitamin C supplementation, but bleeding symptoms eventually returned despite high-dose oral supplementation with 2000 mg daily. She ultimately required routine intravenous supplementation in the home setting for the normalization of levels and the resolution of symptoms. Case reports of vitamin C deficiency typically involve patients with an inadequate intake of vitamin C-containing foods or inadequate absorption. In contrast, our patient reported a regular intake of vitamin C-containing foods, in addition to oral supplementation, but continued to have difficulty maintaining normal vitamin C levels. Scurvy should be considered for any patient with symptoms of bleeding, petechiae, or ecchymosis and, although it can typically be treated with oral vitamin C, intravenous repletion may be necessary in some cases.
