Continuing Professional Development through the lens of complexity science: Becoming agents of change in the healthcare system

This article was migrated. The article was marked as recommended. Healthcare improvement initiatives have not led to expected changes in patient population outcomes over the last decade. This can, in part, be explained by overly reductionist approaches in medical practice and education. This article describes some insights and experiences using a Complex Adaptive Systems approach in the conceptualisation of an in-service training program and reflections on elements that may lead to enhanced practice behaviours and system improvements.

Teaching academic skills to students with significant intellectual disabilities: A systematic review of the single-case design literature

Students with significant intellectual and developmental disabilities deserve access to instruction on academic skills in addition to functional skills. Many teachers, however, report challenges with identifying appropriate evidence-based practices to teach academics to these students. The purpose of this systematic review was to summarize and analyze literature on academic instruction for students with significant disabilities. Two hundred twenty-two articles with 225 experiments utilizing a single-case design and published between 1976 and 2018 were included in the review. Visual analysis indicated that, in most cases, interventions enabled students to make progress on targeted academic skills. The majority of studies focused on basic reading skills and included participants with moderate disabilities. Most studies used a combination of three or four evidence-based practices, with modeling, prompting, visual supports, time delay, and reinforcement being the most frequently used combination across studies.

The development of an iPad application for the pain assessment of individuals with developmental disabilities and complex communication needs

Aims: Develop a new pain assessment for youth with communication challenges. The Guard-Putzer Pain Assessment Domains (gPAD) mobile application (app) was designed and tested as a universally accessible way for youth, ages 7-12 years, with a developmental disability (DD) to express their pain experiences through self-report. Methods: A two-phase process developed the design for an app, created an interactive prototype, and tested its face validity and user interface. This work included a comprehensive scoping review of current assessments and pain apps as well as a survey to obtain descriptive data on the clinical practicality of the gPAD to guide the app design. Additionally, 15 therapists reviewed the gPAD assessment. Results: Thirteen respondents (87%) agreed to the statement that they would use the gPAD for this population. School-based practitioners seemed to highlight the most significant needs for the app. Conclusions: Advancement of this app could mainstream the assessment of pain in youth with DD, and other potential populations.

Parental experiences of telerehabilitation for children with special needs: An exploratory survey

CONTEXT

The COVID-19 pandemic's emergence necessitated that clinic/hospital-based rehabilitation is replaced or substituted by other modes. Using telecommunication devices was found a convenient alternative.

AIMS

Present study explored the telerehabilitation experiences of the parents of children with developmental disabilities (CDD).

SETTINGS AND DESIGN

The study was conducted among the service users of a not-for-profit NGO located in Kerala. Parents of children with one or more developmental disabilities formed the population of the present study. The present study was a cross-sectional exploratory survey.

SUBJECTS AND METHODS

A total of 205 parents took part in the study using a brief open-ended survey. The majority of the participants were females (65%).

STATISTICAL ANALYSIS USED

The sociodemographic data were analyzed using frequency and percentage. The qualitative data were analyzed using thematic analysis.

RESULTS

Overall, the study found that parents experienced more challenges in telerehabilitation compared to face-to-face interventions. Perceived challenges included externalizing problems, reduced effectiveness, logistical issues, multiple disabilities, and the child's lack of interest in gadgets. Perceived advantages included the child's liking for the device and increased availability of time.

CONCLUSION

In short, the study throws light on the various challenges experienced by parents in implementing telerehabilitation for their CDD. The findings strongly recommend fine-tuning telerehabilitation programs to meet these challenges to provide optimal care to our children with special needs.

3-Hydroxyisobutyryl-CoA hydrolase deficiency in an infant with developmental delay and high anion gap acidosis

Due to the rarity of this disorder, paying attention to diagnostic clues is important. Low valine formula seems to be effective in improvement of patient's symptoms. Prevention of consanguineous marriage is the best way to prevent this disease.

Co-occurring intellectual disability and substance use disorders

Individuals with intellectual disabilities (ID) are an expanding population that confronts multiple disadvantages from social and environmental determinants of health. Deinstitutionalization and community integration have improved the lives of individuals with ID in many ways. However, deinstitutionalization may increase their access to alcohol and drugs and the potential for developing Substance Abuse Disorders (SUD). It is estimated that 7–8 million people in the United States with an intellectual disability (ID) suffer disproportionately from substance use problems [1]. There is a lack of empirical evidence to inform prevention and treatment efforts in this population and more research needs to be done in order to address these issues.

Oral health care and service utilisation in individuals with Rett syndrome: an international cross-sectional study

BACKGROUND

There is a dearth of literature available on the comparative oral health status of those with Rett syndrome (RTT) despite diurnal bruxism being a supportive diagnostic criterion for the disorder. This study was designed to investigate the dental experiences of individuals with RTT in terms of perceived at-home and professional dental care.

METHODS

Using data in the InterRett database, provided by English-speaking families of individuals with a confirmed MECP2 genetic mutation, the study investigated relationships between dental problems, oral care, child factors including bruxism and use of gastrostomy, and socioeconomic indicators. The study also explored relationships between dental presentations and socioeconomic, child, and family-related factors.

RESULTS

Individuals with RTT exhibiting bruxism were more likely to access dental treatment. Those who had full oral feeding had a higher incidence rate of dental treatment than those with full tube feeding. A conservative (under) estimation of the overall dental caries progression rate revealed that this may be similar to that of the normal population.

CONCLUSIONS

Drivers for dental treatment in RTT include bruxism as well as dental caries. Those who have full oral feeding experience more dental treatment than those with full tube feeding. A higher maternal education level may confer a protective effect for oral health outcomes in those with RTT. Nevertheless, families generally tended to value the importance of oral health despite reported difficulties in day-to-day mouth care.

The Journey of Humanizing Care for People With Disabilities

The Max Bramer keynote address at the annual Special Care Dentistry Association (SCDA) conference provided an opportunity for reflection on our journey as health care professionals to humanize care for all people, and particularly those who are disabled. It is important to review the history of disability and discrimination to understand the progress made to date, and then consider the array of steps possible in further refining the humanistic dimensions of dental care. The typologies of tourist, traveler, adventurer, and scout were formulated to consider varieties of humanized care found within articles published in Special Care in Dentistry. Considering exemplars for each of these four typologies leads to reflections about how dentistry can embrace understanding, improve training of new dental professionals, tailor care for people with disabilities, and advocate for equity.

Oral parafunction and bruxism in Rett syndrome and associated factors: An observational study

OBJECTIVES

To explore patterns of parafunction, and bruxism, and its relationships with genotype and snoring in individuals with Rett syndrome (RTT).

METHODS

Retrospective observational data of those with confirmed MECP2 mutations in the InterRett database (n = 216) were used to investigate experience of parafunctional habits, and bruxism and their relationships with genotype and snoring using multivariable linear regression.

RESULTS

The prevalence of parafunction was 98.2%. Bruxism was reported (66.2%) with the patterns mostly both diurnal and nocturnal (44.1%) and exclusively diurnal (42.7%). Compared to individuals with C-terminal deletion, individuals with p.Arg106Trp mutations were less likely to have bruxism reported (aOR = 0.15; 95% CI 0.02-0.98, p = 0.05) and those with p.Arg168* mutation were more likely to have frequent bruxism than none or occasional bruxism reported (aROR 3.4; 95% CI 1.1-10.7 p = 0.04). The relative odds of having nocturnal bruxism constantly, compared to none/occasionally, were higher among those 'always' snoring (aROR 6.24; 95% CI 2.1-18.2, p = 0.001) than those with no snoring.

CONCLUSIONS

There appeared to be genotypic association with bruxism in p.Arg168* and p.Arg106Trp mutations and association between nocturnal bruxism and frequent snoring in an international sample of individuals with RTT. Clinical significance of the high prevalence of bruxism should be highlighted in relation to difficulty communicating pain and increased dental treatment need in RTT.

Disability in Childhood, Special Education Histories, and Lifetime Health Outcomes in the United States

Objectives: We evaluated special education as an indicator of childhood disability and used that indicator to estimate lifetime dependency and life expectancy. Methods: Data: Panel Study of Income Dynamics and Health and Retirement Study (n = 20,563). Dependency: Nursing home care or equivalent. Analysis: We first analyzed special education as an indicator of childhood disability; multinomial logistic Markov models and microsimulation then compared populations with and without childhood disability. Results: Special education history was a valid indicator of childhood disability. For example, with parents who did not complete high school, 3.8% with no special education history were dependent at least 5 years of adult life; that result with special education was 15.2%. Life expectancy from age 20 was 58.3 years without special education, 46.0 years with special education (both p < .05). Discussion: Special education history can indicate childhood disability. People with that history had significantly a more dependency than others and significantly shorter lives.

Social attention as a cross-cultural transdiagnostic neurodevelopmental risk marker

The primary objectives of this study were to evaluate the structure and age-related stability of social attention in English and Arabic-speaking youth and to compare social attention between children with autism spectrum disorder (ASD), other developmental disabilities (DD), and typically-developing controls. Eye-tracking data were collected from US (N = 270) and Qatari (N = 242) youth ages 1-17, including children evaluated for possible ASD. Participants viewed 44 stimuli from seven social paradigms. Fixation was computed for areas of interest within each stimulus. Latent variable models examined the structure of social attention. Generalized estimating equation models examined the effect of age, sex, culture, and diagnostic group on social attention. The best-fitting model included a general social attention factor and six specific factors. Cultural differences in social attention were minimal and social attention was stable across age (r = 0.03), but females showed significantly greater social attention than males (d = 0.28). Social attention was weaker in DD (d = -0.17) and lowest in ASD (d = -0.38) relative to controls. Differences were of sufficient magnitude across areas-of-interest to reliably differentiate DD from controls (AUC = 0.80) and ASD-only from all other cases (AUC = 0.76). A social attention dimension that represents an early-life preference for socially salient information was identified. This preference was cross-culturally consistent and stable across development but stronger in females and weaker in DD, especially ASD. Given rapid and easy-to-collect remote eye tracking administration, social attention measurement may be useful for developmental monitoring. Acquisition of population norms, analogous to height/weight/head circumference, might enhance early screening and tracking of neurodevelopment. LAY SUMMARY: This research found that social attention is a single dimension of behavior that represents a strong preference for social stimuli, is consistent across cultures, stable across age, and stronger in females. Children with developmental disabilities had lower levels of social attention than neurotypical children and children with autism spectrum disorder had the lowest levels of social attention.

Current practice and adaptations being made for people with autism admitted to in-patient psychiatric services across the UK

BACKGROUND

A significant number of people with autism require in-patient psychiatric care. Although the requirement to adequately meet the needs of people with autism in these settings is enshrined in UK law and supported by national guidelines, little information is available on current practice.

AIMS

To describe characteristics of UK in-patient psychiatric settings admitting people with autism. Also to examine psychiatric units for their suitability, and the resultant impact on admission length and restrictive interventions.

METHOD

Multiple-choice questions about in-patient settings and their ability to meet the needs of people with autism and the impact on their outcomes were developed as a cross-sectional study co-designed with a national autism charity. The survey was distributed nationally, using an exponential and non-discriminatory snowballing technique, to in-patient unit clinicians to provide a current practice snapshot.

RESULTS

Eighty responses were analysed after excluding duplications, from across the UK. Significant variation between units across all enquired parameters exist. Lack of autism-related training and skills across staff groups was identified, this becoming disproportionate when comparing intellectual disability units with general mental health units particularly regarding psychiatrists working in these units (psychiatrists: 94% specialist skills in intellectual disability units versus 6% specialist skills in general mental health units). In total, 28% of survey respondents felt people with autism are more likely to be subject to seclusion and 40% believed in-patients with autism are likely to end in segregation.

CONCLUSIONS

There is no systematic approach to supporting people with autism who are admitted to in-patient psychiatric units. Significant concerns are highlighted of lack of professional training and skill sets resulting in variable clinical practice and care delivery underpinned by policy deficiency. This could account for the reported in-patient outcomes of longer stay and segregation experienced by people with autism.

Conversation turns and speaking roles contributed by Mandarin Chinese dyadic conversations between adults who use speech-generating devices and adults who use natural speech

Few studies have critically examined contributed conversation turns and speaking roles in dyadic Mandarin Chinese conversations between adults who use natural speech and adults who use SGDs. An analysis of conversation turns considers how conversation participants co-construct conversation processes, whereas an analysis of speaking roles considers how conversation participants co-construct conversation contents. The purpose of the current study was to explore the quantitative contributions of conversation turns and speaking roles in familiar Mandarin Chinese conversation dyads between adults who use SGDs and adults who use natural speech. Five dyads were recruited, and each dyad contained two participants; an adult using an SGD and an adult using natural speech. Each dyadic conversation was individually video-recorded for about 20 minutes, six times. A total of 30 dyadic conversations were analyzed. The means and percentages of the coded conversation turns and speaking roles were computed. Quantitatively asymmetrical contributions of conversation turns and speaking roles occurred in the Mandarin Chinese conversation dyads between the adults who use SGDs and the adults who use natural speech. The adults who use natural speech contributed significantly more conversation turns and speaking roles than did the adults who use SGDs. Implications, limitations, and further research studies were discussed.

Health-Related Quality of Life After Community-Acquired Septic Shock in Children With Preexisting Severe Developmental Disabilities

OBJECTIVES

To serially evaluate health-related quality of life during the first year after community-acquired septic shock in children with preexisting severe developmental disabilities and explore factors associated with health-related quality of life changes in these children.

DESIGN

Secondary analysis of the Life after Pediatric Sepsis Evaluation investigation.

SETTING

Twelve academic PICU in the United States.

PATIENTS

Children greater than or equal to 1 month and less than 18 years old identified by their family caregiver (e.g., parent/guardian) as having severe developmental disability prior to septic shock.

INTERVENTIONS

Family caregivers completed the Stein-Jessop Functional Status II-R Short Form as a measure of their child's health-related quality of life at baseline (reflecting preadmission status), day 7, and months 1, 3, 6, and 12 following PICU admission. Stein-Jessop Functional Status II-R Short Form scores were linearly transformed to a 0-100 scale, with higher scores indicating better health-related quality of life.

MEASUREMENTS AND MAIN RESULTS

Of 392 Life after Pediatric Sepsis Evaluation participants, 137 were identified by their caregiver as having a severe developmental disability. Sixteen children (11.6%) with severe disability died during the 12 months following septic shock. Among 121 survivors, Stein-Jessop Functional Status II-R Short Form scores declined from preadmission baseline to day 7 (70.7 ± 16.1 vs 55.6 ± 19.2; p < 0.001). Stein-Jessop Functional Status II-R Short Form scores remained below baseline through month 12 (59.1 ± 21.0, p < 0.001 vs baseline). After adjusting for baseline Stein-Jessop Functional Status II-R Short Form, the caregiver being a single parent/guardian was associated with lower month 3 Stein-Jessop Functional Status II-R Short Form scores (p = 0.041). No other baseline child or caregiver characteristic, or critical illness-related factors were significantly associated with month 3 Stein-Jessop Functional Status II-R Short Form scores.

CONCLUSIONS

Health-related quality of life among children with severe developmental disability remains, on average, below baseline during the first year following community-acquired septic shock. Children with severe disability and septic shock that are in single parent families are at increased risk. Clinical awareness of the potential for decline in health-related quality of life among disabled children is essential to prevent this adverse outcome from being missed.

Perceptions of people with intellectual and developmental disabilities about COVID-19 in Spain: a cross-sectional study

BACKGROUND

As the world battles COVID-19, there is a need to study the perceptions of people with intellectual and developmental disabilities (IDD) about the effects of the pandemic and associated lockdown on their lives. This work explores the perceptions of Spaniards with IDD during the lockdown with respect to four topics: access to information, emotional experiences, effects on living conditions and access to support.

METHODS

The topics were explored using a subset of 16 closed-ended questions from an online survey. In total, 582 participants with IDD completed the survey. The frequencies and percentages of responses to the questions were calculated, and chi-square tests performed to explore the relationship between participants' sociodemographic characteristics and responses. Given that people differed in the way in which they completed the survey, the relationship between participants' responses and completion method was also analysed.

RESULTS

Participants reported that the pandemic and subsequent lockdown have had a deleterious effect on their emotional well-being (around 60.0% of participants) and occupations (48.0% of students and 72.7% of workers). Although access to information and support was reportedly good overall, being under the age of 21 years and studying were associated with perceptions reflecting poorer access to information (V = .20 and V = .13, respectively) and well-being support (V = .15 and V = .13, respectively). Being supported by a third party to complete the survey was consistently related to perceptions of worse outcomes.

CONCLUSIONS

The study yielded data on the perceptions of people with IDD regarding the effects that COVID-19 and the subsequent lockdown have had on their lives. Suggestions on how to overcome the difficulties reported and future lines of research are discussed.

Developmental Dyspraxia in Children With Learning Disorders: Four-Year Experience in a Referred Sample

OBJECTIVE

The term apraxia is clearly understood in adult behavioral neurology, with assessment of gesture central to the diagnosis. In contrast, the concept of "developmental dyspraxia" has been more problematic. In an effort to better specify its potential significance, we describe preliminary practice-based evidence for understanding developmental dyspraxia acquired within a theoretical framework informed by both adult behavioral neurology and a neuroconstructivist appreciation of neurodevelopmental disorders. Specifically, we describe the experience of a diagnostic clinic for children with learning disorders that adopted this framework and compare clinical characteristics of children diagnosed with dyspraxia with those of children diagnosed with dyslexia during the same time period.

METHOD

The dyspraxia diagnosis was based on the presence of impaired gesture and/or cognitive problems with planning. Over the target period, 71 children were diagnosed with dyspraxia and 114 children were diagnosed with dyslexia. Twenty-nine of the 71 children with dyspraxia were also diagnosed with dyslexia. Domains assessed included early developmental milestones, neurologic findings, cognition, speech and language, academic skills, and psychosocial functioning.

RESULTS

Compared to the dyslexia group, children with dyspraxia (with or without dyslexia) had more problems with speech and language planning and planning in everyday life. Children with dyspraxia without dyslexia had more frequent early motor delays and deficits in visuospatial production than the other groups. The dyslexia groups predictably demonstrated poorer single word reading and phonologic processing compared to the dyspraxia only group (all P < .01).

CONCLUSIONS

A neurologic finding of impaired gesture in children with learning disorders may signal a broader neurodevelopmental profile of developmental dyspraxia with both theoretical relevance and meaningful implications for evaluation and treatment. Cognitive problems with planning are particularly relevant.

Oral health perceptions, behaviors, and barriers among differently abled and healthy children

AIM

To describe and compare the oral health perceptions, behaviors, and barriers for utilization of dental care among differently abled and healthy children.

METHODS

Participants in this cross-sectional study were differently abled and healthy children belonging to the age group of 7-15 years. A questionnaire for measuring the children's perceptions, behaviors, and barriers was developed, validated, and applied to this study. Cronbach's α was calculated to test reliability, and test-retest reliability was assessed by Pearson's correlation test. Chi-square/Fisher exact test, Mann-Whitney U test, and factor analysis were also applied. Statistical significant differences were defined as P < 0.05, two-tailed.

RESULTS

A total number of 300 children in each group participated in the study. The correlations of test and retest for the questionnaire ranged from 0.69 to 0.86 (P < 0.05) with Cronbach's α score of 0.862. More than half in both the groups were aware of the presence of fluoride in their toothpaste, and parents agreed that a child's dental health is satisfactory yet only one-third of them perceived dental problems as serious. Regarding brushing twice daily, the frequency was better in the study group (26.3% and 17.3%, P = 0.01), most of them changed their toothbrush between 3 and 6 months (67.3% and 82.0%, P < 0.001), and tongue cleaner were regularly used as an oral hygiene aid (62.3% and 88.5%, P = 0.01). Members of the study group appear to have visited the dentist (26.0%) more as compared to the control group (17.7%) (P = 0.01), and most of the respondents (50.0% and 41.5%) consulted the dentist on account of dental caries. In the study group, no priority care (8.82±2.81), difficulty in communicating with the dentist (7.85±1.92), treatment cost (6.90±1.98) and fear of dental instruments (6.90±1.98), respectively, were the barriers with the highest means of scores, whereas in the control group it was related to affordability and fear. Facilities in dental clinics excluding wheelchairs (76.3% and 76.7%) and corridor signs (66.3% and 61.7%) were lacking.

CONCLUSION

Knowledge and attitude scores were adequate but there was a discrepancy present concerning oral health practices. Dental health was not viewed as a threat, and therefore, not many visited the dentist. Priority care and communication problems were the central issues among differently abled children, while among healthy children, the main factor was cost and fear.

Motivation for change in the health care of children with developmental disabilities: Pilot continuing professional development-quality improvement project

AIM

People with developmental disabilities (DDs) experience significant barriers accessing and receiving optimal health care resulting in poorer health-care outcomes. Continuing professional development (CPD) represents an effective means to alter health-care staff behaviour to improve the care of people with DDs. However, given the scepticism regarding the effectiveness of certain CPD models' ability to alter learner's workplace behaviour, the current pilot study developed and determined the feasibility of a novel CPD programme aimed at improving the health care provided to children with DDs.

METHODS

Motivation for Change (MFC) is a novel CPD programme based on empirically based behaviour and educational strategies including motivational interviewing, flipped classroom and process mapping. It utilises input of patients, practitioners, and family members during administration of the programme. MFC was administered with 14 staff members in a Sydney Children's Hospital Sleep service.

RESULTS

After MFC engagement, staff reported significant improvements in their knowledge of behavioural characteristics of children with DDs, the difficulties they face, how best to support them within the learner's work setting and confidence in working with children with DDs. There was a non-significant decline in their reported need for further training and expressed high level of satisfaction with the MFC programme.

CONCLUSION

MFC represents a feasible means of providing CPD to health-care staff but further research is needed to determine objective clinical behavioural change. Evaluation of the impact on patient health outcomes, parent/child satisfaction, staff sustainability and overall system functioning is also needed. It may represent an effective model of CPD for other targets of health-care improvement.

Rationale, Development, and Description of a Brief Family-Centered Service Provision Model for Addressing Children's Severe Behavior

For families with children with autism that engage in severe behavior, the American Academy of Pediatrics recommends that functional assessment and management of environmental variables contributing to severe behavior occur prior to the prescription of psychopharmacologic treatment. Despite the inclusion of this recommendation in guidance articles published in pediatric journals for more than a decade, access to such services may not be feasible, in particular for families living in rural and geographically isolated communities. Given that families often view pediatricians as their first line of professional guidance for addressing challenges surrounding child development, the inaccessibility of appropriate services for managing healthcare is a concern for many pediatricians. To address this issue, a brief family-centered service provision model was developed through a collaboration between healthcare providers at a university-based hospital and Applied Behavior Analysis program faculty of the affiliated university. The hospital served many families living in rural areas of the state; therefore, the model utilized research-based practices with evidence of ecological validity for providing function-based assessment and treatment services. Within this manuscript we present a description of the model and its current implementation at a university-based hospital. For a data-based evaluation of the clinic and model, we refer readers to https://osf.io/qx8ak.

Examining the Suitability of the List of Indicators Describing Age-Related Typical Support Needs

The list of indicators is a form of training material used for the Supports Intensity Scale—Children’s version (SIS-C). It is aimed at helping interviewers distinguishing between extraordinary and age-related typical support needs in children with intellectual and developmental disabilities (IDD) when implementing the SIS-C, and thus improve supports planning. The aim of this study is to adapt and test the list of indicators’ content validity and rating scale’s functioning in Spain. A total of 222 general education teachers reported their agreement with each indicator description using a 5-point rating scale. A total of 353 of 366 indicators showed evidence of content validity, whereas analyses on the rating scale highlighted the necessity of subsuming one of the scale categories within another. The need for developing research-based training materials to develop training programs on the use of the SIS-C to support decision-making concerning supports planning with students with IDD, the relevance of using the latest methodological approaches available when required, and future lines of research are discussed.

Identification of 16p11.2 deletion syndrome on a child inpatient psychiatric unit: A case report and call for inpatient genetic testing

PURPOSE

This case highlights the importance of nursing-directed interprofessional treatment and inpatient unit genetic testing to identify genetic syndromes that may potentiate psychiatric conditions.

SOURCES USED

A case study of a 10-year-old Caucasian male with a history of a congenital heart defect, hand malformation, and low academic functioning who was admitted to the child inpatient psychiatric unit for eloping from school, aggression, and possible psychotic symptoms. Data were collected using patient medical records and interprofessional evaluation from nursing, psychiatry, and occupational therapy.

RESULTS

The patient was treated with risperidone to manage psychotic symptoms. Dietary, occupational therapy, and scholastic plans were also implemented. After discharge, results of genetic microarray analysis revealed a Type 1 16p11.2 deletion.

CONCLUSION

The role of nursing, interprofessional collaboration, and access to consultation teams play a crucial role in patient care for early diagnosis and treatment. Inpatient genetic testing has the potential to quickly identify and diagnose previously unidentified symptom clusters, leading to early intervention, closer monitoring, and improved patient outcomes.

Chromosomal Microarray in Children With Developmental Delay: The Experience of a Tertiary Center in Korea

Background and Objectives: Chromosomal microarray (CMA) is a first-tier genetic test for children with developmental delay (DD), intellectual disability (ID), autism spectrum disorders (ASDs), and multiple congenital anomalies (MCA). In this study, we report our experiences with the use of CMA in Korean children with unexplained DD/ID. Methods: We performed CMA in a cohort of 308 children with DD/ID between January 2010 and September 2020. We also retrospectively reviewed their medical records. The Affymetrix CytoScan 750 K array with an average resolution of 100 kb was used to perform CMA. Results: Comorbid neurodevelopmental disorders were ASD (37 patients; 12.0%), epilepsy (34 patients; 11.0%), and attention deficit hyperactivity disorders (12 patients; 3.9%). The diagnostic yield was 18.5%. Among the 221 copy number variants (CNVs) identified, 70 CNVs (57 patients; 18.5%) were pathogenic. Deletion CNVs were more common among pathogenic CNVs (PCNVs) than in non-PCNVs (P < 0.001). The size difference between PCNVs and non-PCNVs was not significant (P = 0.023). The number of included genes within CNV intervals was significantly higher in PCNVs (average 8.6; 0-347) than in non-PCNVs (average 47.5; 1-386) (P < 0.001). Short stature and hearing difficulty were also more common in the PCNV group than in the non-PCNV group (P = 0.010 and 0.070, respectively). Conclusion: This study provides additional evidence for the usefulness of CMA in genetic testing of children with DD/ID in Korea. The pathogenicity of CNVs correlated with the number of included genes within the CNV interval and deletion type of the CNVs, but not with CNV size.

Surviving and Thriving: Early Intervention for Neonatal Survivors With Developmental Disability in Uganda

Global attention on early child development, inclusive of those with disability, has the potential to translate into improved action for the millions of children with developmental disability living in low- and middle-income countries. Nurturing care is crucial for all children, arguably even more so for children with developmental disability. A high proportion of survivors of neonatal conditions such as prematurity and neonatal encephalopathy are affected by early child developmental disability. The first thousand days of life is a critical period for neuroplasticity and an important window of opportunity for interventions, which maximize developmental potential and other outcomes. Since 2010, our group has been examining predictors, outcomes, and experiences of neonatal encephalopathy in Uganda. The need for an early child intervention program to maximize participation and improve the quality of life for children and families became apparent. In response, the "ABAaNA early intervention program," (now re-branding as 'Baby Ubuntu') a group participatory early intervention program for young children with developmental disability and their families, was developed and piloted. Piloting has provided early evidence of feasibility, acceptability, and impact and a feasibility trial is underway. Future research aims to develop programmatic capacity across diverse settings and evaluate its impact at scale.
