Background and objective
Recognizing the common co-occurring conditions among individuals with Down syndrome (DS) is essential for maintaining appropriate screening and optimizing healthcare resources. However, many previous studies relied on hospital- or community-based convenience samples with small sample sizes, limiting their generalizability. This study aimed to investigate the association between DS and co-occurring conditions in a large cohort of children and young adults.
Methods
We conducted a population-based retrospective cohort study using Danish national registers. The cohort had 1779912 participants born from 1977 to 2013 including 1385 with DS. For congenital conditions, we estimated inverse-probability-weighted (IPTW) absolute prevalence and prevalence difference. Time to event analyses (proportional hazard regression and IPTW cumulative incidence function estimation) were utilized to estimate the association between DS and risk for non-congenital co-occurring conditions. Sub-analyses examined risks among individuals with leukemia and sex-specific differences.
Results
Analyses showed very large prevalence ratios for many congenital conditions, including atrioventricular septal defects (PD=0.181, 95 % CI: 0.162, 0.203; PR=489, 95 % CI: 425–562), atrial septal defects (PD=0.215, 95 % CI: 0.194, 0.238; PR=94, 95 % CI: 84–105), and tetralogy of Fallot (PD=0.020, 95 % CI: 0.014, 0.029; PR=67, 95 % CI: 45–99). Individuals with DS had higher risks for cardiovascular disorders: pulmonary hypertension (HR=103.44, 95 % CI: 71.26–150.15), and stroke (HR=6.50, 95 % CI: 3.09–13.65). Additionally, the diagnosis was associated with increased risks of autoimmune diseases including celiac disease (HR=14.03, 95 % CI: 10.65–18.49) and type 1 diabetes (HR=3.40, 95 % CI: 2.08–5.54). Positive associations were also found for cerebral palsy (HR=9.77, 95 % CI: 7.32–13.06), and respiratory failure (HR=12.97, 95 % CI: 9.30–18.10). At 30 years of follow-up, IPTW absolute risks illustrated the clinical burden: e.g., pulmonary hypertension (AR1=0.028 vs AR0=0.0002, RD=0.026, RR=138.50), keratoconus (AR1=0.025 vs AR0=0.006, RD=0.025, RR=43.19), and respiratory failure (AR1=0.034 vs AR0=0.002, RD=0.031, RR=13.98).
Discussion and conclusion
Individuals with DS have notably higher risks of many co-occurring conditions. Our findings suggest that attention should be given to the management of autoimmune and ophthalmologic conditions, particularly regarding their incidence patterns over time and by gender.

Background
Autism Spectrum Disorder (ASD) is a prevalent neurodevelopmental condition globally, including in Arab countries, where stigma, limited awareness, and scarce specialized services often delay diagnosis and care. Artificial intelligence (AI) offers scalable solutions for screening, early diagnosis, and intervention programmes.
Aims
To evaluate the diagnostic accuracy of AI-based models for ASD with a specific focus on Arab cohorts, and to appraise methodological quality and potential cultural influences on model performance.
Methods
We searched PubMed, Scopus, and Web of Science for studies published between January 2019 and September 2025. Eligible studies evaluated supervised AI systems, machine learning (ML), or deep learning (DL) that classify individuals as ASD versus non-ASD against a clinician-confirmed reference standard. Study quality was assessed using QUADAS-2. Diagnostic accuracy metrics (sensitivity, specificity, likelihood ratios, diagnostic odds ratio) were pooled using a bivariate random-effects model.
Results
Fifteen studies were included in the systematic review; ten studies were eligible for meta-analysis (59 model evaluations; 26,569 instances), comparing AI models against clinician-confirmed autism diagnoses. Pooled sensitivity was 91.8 % (95 % CI [89.0, 94.2]) and specificity 90.7 % (95 % CI [87.6, 93.5]), yielding a diagnostic odds ratio (DOR) of 109.0 (95 % CI [59.5, 227.9]), positive likelihood ratio (LR⁺) of 9.8, and negative likelihood ratio (LR⁻) of 0.09. Subgroup analysis revealed hybrid models (deep feature extractors with classical classifiers) achieved the highest accuracy (sensitivity 95.2 %, specificity 96.0 %), followed by conventional ML (sensitivity 91.6 %, specificity 90.3 %), and DL alone (sensitivity 87.3 %, specificity 86.0 %). In Arab-only cohorts, models showed higher sensitivity (94.2 %) but lower specificity (87.6 %), suggesting stronger rule-out potential but more false positives.
Conclusion
To our knowledge, this is the first systematic meta-analysis of AI-based ASD diagnostics confirms high accuracy, with hybrid models excelling compared to both traditional ML and DL alone. In Arab cohorts, models showed higher sensitivity but lower specificity, highlighting the importance of cultural and linguistic tailoring of assessment tools, diagnostic protocols, and datasets, alongside regional challenges such as stigma and limited resources. These findings support AI as a valuable tool for early detection and screening.

Background
Children with Down syndrome (DS) often face challenges maintaining adequate levels of physical activity, which might be associated with their mobility performance. Therefore, the objectives of this study were i) to describe parent-reported physical activity level and performance of mobility of children with DS and ii) to explore relationship between parent-reported physical activity level and performance of mobility in children with Down syndrome.
Methods
For this observational and cross-sectional study, 48 children with DS (mean age: 10.50 ± 3.30) were assessed using the IPAQ-short version (parent-reported physical activity level) and the PEDI-CAT mobility (performance in mobility). Data were analyzed using the Spearman correlation test with a significance level of p < 0.05 using SPSS-V24.0 software.
Results
A significant positive association was found between parent-reported physical activity level and mobility performance (ρ (rho) = .323; p = .025).
Conclusion
Higher physical activity level was associated with better mobility performance in daily living activities. Therefore, this finding supports the importance of promoting both aspects of functioning in children with DS.

Background
The concept of quality of life (QoL) is comprehensive and complex, particularly when considering people with intellectual disabilities (ID). Such individuals often face numerous challenges in their lives, which adversely affect their overall QoL.
Objectives
The primary aim of this research was to evaluate the QoL that Saudi children and young people with ID experience in terms of interpersonal relationships, self-determination, social inclusion, personal development, and emotional well-being. Additionally, the research considered several factors that could potentially influence these areas, including gender, family income, parents' education, and geographical location.
Methodology
A cross-sectional study was carried out among 142 children and young people with ID representing various regions of Saudi Arabia.
Results
The study established that Saudi Arabian children and adolescents with ID have, in general, a moderate QoL, with difficulties in social integration and emotional well-being. Self-determination and interpersonal relationships were found to be influenced by demographic characteristics, including the parents' educational background and gender, with girls exhibiting a higher level of self-determination.
Implications
The results of this study have important implications for stakeholders, such as policymakers and parents, particularly regarding the areas where the QoL of individuals with ID may be enhanced. Furthermore, the results draw attention to the need for targeted interventions for boys, who were shown to have lower QoL.

Improving quality of life (QoL) for individuals with blindness and visual impairment (BVI) is integral to encouraging their active participation in society, thereby promoting positive social change and creating a more promising future. This qualitative study adopts an intrinsic case study design to explore a Saudi family comprising five highly educated members (one male and four females) who have inherited blindness. They live with their sighted parents and two siblings in the same house in Riyadh, the capital city of Saudi Arabia, and are professionally active as freelancers, advertisers, teachers, and postgraduate students. This approach was chosen to gain an in-depth understanding of the lived experiences of participants who are blind from birth (BfB), focusing on key factors that impact their QoL. Data were collected using a triangulated methodology, including in-depth semi-structured interviews, live recordings, and analysis of artefacts. Theoretical coding analysis revealed four main themes representing factors that impact QoL: (a) life orientation and mobility, (b) information accessibility, (c) employment opportunities, and (d) loneliness and social isolation. These themes encompassed 15 subthemes and 57 individual codes. Findings indicated that participants who are BfB demonstrate strong adaptive skills, digital independence, and psychological resilience, yet continue to confront barriers related to environmental accessibility, assistive technology, and workplace inclusion. A 3 × 4 conceptual model was developed to illustrate the factors influencing the QoL of BfB individuals. The study concludes by recommending solutions that promote the role of education and implementation to enhance QoL for all individuals with BVI.

Background
Parental support constitutes a critical determinant of physical activity (PA) engagement in children and adolescents with autism spectrum disorder (ASD), yet its predictors remain understudied. Grounded in an extended Theory of Planned Behavior (TPB) framework, this study examines the sequential relationships between parental support intention, parental action planning, parental support, and PA in this population.
Methods
A cross-sectional survey was conducted with 164 parents/caregivers of children and adolescents with ASD in China. The parents/caregivers completed a survey form measuring key TPB constructs of interest.
Results
Only 18.3 % of children and adolescents with ASD met the WHO’s recommended guideline of at least 60 min of daily PA. Path analysis revealed that parental support intentions directly predicted parental action planning (β = 0.52) and parental support (β = 0.34), while action planning mediated the intention-behavior relationship. Further, parental support mediated the intention-PA association (β = 0.41) and served as the critical pathway linking intention to children's PA through a chain mediation model (support intention → action planning → parental support → PA).
Conclusion
The extended TPB model elucidates the mechanisms underlying parental support for children and adolescents with ASD. These findings underscore the necessity to strengthen parental intentions, develop actionable plans, and implement integrated support strategies for promoting PA in this population.

The objective of this study is to examine the macroeconomic effects of disability-inclusive labor regulations in Saudi Arabia. A dynamic Computable General Equilibrium (CGE) model is calibrated to a commodity-disaggregated Social Accounting Matrix (SAM). The study simulates two policy scenarios: a general employment quota and a service-sector-specific quota for persons with disabilities (PWDs). Each scenario is evaluated under different elasticity of substitution parameters (σ = 0.8, 1.0, 1.5) to capture the sensitivity of the economy to production flexibility. The findings indicate that both regulatory policies produce positive macroeconomic impacts, particularly in scenarios of low substitution elasticity, reflecting limited capacity of firms to replace PWD labor with alternative inputs. Under such conditions, increased PWD employment enhances real GDP, amplifies household consumption, stimulates investment, and yields GDP multipliers exceeding 2.0. Nevertheless, when production flexibility rises (σ = 1.5), the beneficial economic impacts diminish, resulting in GDP multipliers falling below 1.0, indicating less responsiveness and constrained supplementary employment or investment. The study highlights the importance of labor market structure in determining the effectiveness of inclusive employment policies. In less flexible production systems, disability inclusion fosters robust and sustainable economic benefits. In contrast, adaptable systems may necessitate supplementary measures to sustain the progress of labor inclusion and its impact on economic inclusion and quality of life.

A dynamic Computable General Equilibrium (CGE) model is calibrated to a commodity-disaggregated Social Accounting Matrix (SAM). The study simulates two policy scenarios: a general employment quota and a service-sector-specific quota for persons with disabilities (PWDs). Each scenario is evaluated under different elasticity of substitution parameters (σ = 0.8, 1.0, 1.5) to capture the sensitivity of the economy to production flexibility. The findings indicate that both regulatory policies produce positive macroeconomic impacts, particularly in scenarios of low substitution elasticity, reflecting limited capacity of firms to replace PWD labor with alternative inputs. Under such conditions, increased PWD employment enhances real GDP, amplifies household consumption, stimulates investment, and yields GDP multipliers exceeding 2.0.

Background
While the double ABCX model has been evaluated in various contexts, large-scale studies on gender among parents of children with rare diseases remain scarce.
Objective
To examine the applicability of the double ABCX model within a large-scale sample of mothers and fathers of children diagnosed with rare diseases.
Methods
The potential predictors of parental mental health in a multicenter study of n = 668 mothers and n = 461 fathers of children with rare diseases were investigated. Factors contributing to parental adaptation (GAD-7 and PHQ-9) within the double ABCX model were investigated cross-sectionally using multiple mediation modeling.
Results
In mothers, relevant associations were found among stressor pile-up, social support, parental relationships, coping, stress, and mental health. Similar relevant associations were observed in fathers, except for coping. For mothers, the association between stressor pile-up and symptoms of anxiety was fully mediated by coping and stress. In contrast, the association with symptoms of depression was fully mediated by social support, coping, and stress. For fathers, the association between stressor pile-up and symptoms of anxiety as well as depression was complementary mediated through stress.
Conclusion
Our findings contribute to the existing literature by illuminating gender-specific differences in parental symptoms of anxiety and depression, suggesting that tailored emotion regulation programs could effectively alleviate these issues. By emphasizing these dynamics, we highlight the importance of personalized approaches in addressing the unique challenges faced by parents of different genders.

Purpose
Despite the global recognition of the benefits of companion pet ownership, there is a lack of research exploring this phenomenon in an Arabic-speaking context such as the United Arab Emirates (UAE). This study fills the knowledge gap by exploring the usefulness of pet ownership on the social skills, communication, emotional and physical well-being of children with Autism Spectrum Disorder (ASD) in the UAE.
Materials and methods
The study employs a phenomenological research design, utilizing focus-group discussions with 12 mothers of children diagnosed with ASD who own pets. The parents participated in the focus group discussions to understand the usefulness of pet ownership to their children with ASD.
Results
Findings are categorized into three primary themes: enhancement of social interaction and communication skills, improvement in emotional well-being, and encouragement of physical activity. For instance, the presence of pets, especially dogs, significantly boosts social engagement and non-verbal communication, reduces anxiety and stress, and increases physical activity among children with ASD.
Conclusion
Companion pet ownership may inform family-centered routines for children with ASD in the UAE. Future work should assess the feasibility of structured animal-assisted interventions (AAI), which are distinct from household pet ownership.
