While the benefits of regular participation in physical activity in children and young people are clear, misconceptions have developed about the possible negative effects and potential complications of exercise on long-term conditions such as epilepsy, asthma and diabetes. Over the last decade evidence has emerged supporting the positive impact that physical activity has on long-term conditions. Previous concerns were raised about the risks of hypoglycaemia in children with type 1 diabetes mellitus (T1DM) thus limiting participation in sports. Importantly, physical activity improves the metabolic profile, bone mineral density, cardiorespiratory fitness and insulin sensitivity while lowering mortality risk in children with T1DM. Children with asthma were prevented from doing exercise due to concerns about precipitating an acute asthmatic episode. To the contrary, physical activity interventions have consistently shown an increase in cardiovascular fitness, physical capacity, asthma-free days and quality of life in childhood asthmatics. Children with epilepsy are often excluded from sports due to concerns relating to increased seizure frequency, yet evidence suggests that this is not the case. The evidence supporting physical activity in childhood survivors of cancer is growing but still primarily confined to patients with acute lymphoblastic leukaemia. Participation in sports and physical activity also reduces mental health problems developing in adolescence. While further research is required to investigate benefits of physical activity on specific aspects of long-term conditions in children, in general this group should be advised to increase participation in sports and exercise as a means of improving long-term physical and mental health.

In the last decade, technology has revolutionised the way we deliver healthcare. Smartphones, tablets, personal computers and bespoke devices have provided patients with the means to access health information, manage their healthcare and communicate with health professionals remotely. Advances in technology have the potential to change how acute and long-term conditions are diagnosed and managed and how illness is prevented using technological advances in artificial intelligence, virtual and augmented reality, robotics, 3D printing, new materials, biosensor technologies and data analytics. In the future, predictive analytics will help with earlier disease diagnosis in at-risk populations.Historically, development of child health innovation and technology has taken place in a relatively emergent manner with little formal coordination. The aim is to move away from the traditional approach of repurposing adult technologies to provide a large-scale and coordinated approach for the development of bespoke health technology for children that is anatomically, physiologically and developmentally appropriate, versatile and that has been designed with children and young people. The challenge for the National Health Service alongside healthcare systems across the world is to deliver increasingly complex healthcare at lower cost and with better quality of life and greater efficiency.

A complex interplay of genetic, environmental, hormonal, and behavioral factors affect skeletal development, several of which are associated with childhood fractures. Given the rise in obesity worldwide, it is of particular concern that excess fat accumulation during childhood appears to be a risk factor for fractures. Plausible explanations for this higher fracture risk include a greater propensity for falls, greater force generation upon fall impact, unhealthy lifestyle habits, and excessive adipose tissue that may have direct or indirect detrimental effects on skeletal development. To date, there remains little resolution or agreement about the impact of obesity and adiposity on skeletal development as well as the mechanisms underpinning these changes. Limitations of imaging modalities, short duration of follow-up in longitudinal studies, and differences among cohorts examined may all contribute to conflicting results. Nonetheless, a linear relationship between increasing adiposity and skeletal development seems unlikely. Fat mass may confer advantages to the developing cortical and trabecular bone compartments, provided that gains in fat mass are not excessive. However, when fat mass accumulation reaches excessive levels, unfavorable metabolic changes may impede skeletal development. Mechanisms underpinning these changes may relate to changes in the hormonal milieu, with adipokines potentially playing a central role, but again findings have been confounding. Changes in the relationship between fat and bone also appear to be age and sex dependent. Clearly, more work is needed to better understand the controversial impact of fat and obesity on skeletal development and fracture risk during childhood.

Abstract Introduction Congenital and acquired damage to hypothalamic nuclei or neuronal circuits controlling satiety and energy expenditure results in hypothalamic obesity (HO). To date, successful weight loss and satiety has only been achieved in a limited number of affected patients across multiple drug trials. Glucagon-like peptide-1 (GLP-1) acts via central pathways that are independent from the hypothalamus to induce satiety. GLP-1 receptor agonists (GLP-1RAs) may provide an alternative approach to treating HO. Methods We performed a comprehensive search in Medline, Google Scholar, and clinical trials registries (ClinicalTrials.gov; clinicaltrialsregister.eur). This nonsystematic literature review was conducted to identify scientific papers published from January 2005 to February 2024 using the Pubmed and Embase databases. Key words used were GLP-1, GLP-1RA, hypothalamic obesity, suprasellar tumor, and craniopharyngioma. Results Our search identified 7 case studies, 5 case series, and 2 published clinical trials relating to the use of GLP-1RAs in HO. All case studies demonstrated weight loss and improved metabolic function. In contrast, results from case series were variable, with some showing no weight loss and others demonstrating moderate to significant weight loss and improved metabolic parameters. In the ECHO clinical trial, nearly half the subjects randomized to weekly exenatide showed reduced body mass index (BMI). Paradoxically, BMI reduction was greater in patients with more extensive hypothalamic injuries. Conclusion GLP-1RAs potentially offer a new approach to treating HO. There is a need to stratify patients who are more likely to respond. Further randomized controlled trials are required to determine their efficacy either in isolation or combined with other therapies.

BackgroundFor many children, visiting the hospital can lead to a state of increased anxiety. Social robots are being explored as a possible tool to reduce anxiety and distress in children attending a clinical or hospital environment. Social robots are designed to communicate and interact through movement, music and speech.ObjectiveThis systematic review aims at assessing the current evidence on the types of social robots used and their impact on children’s anxiety or distress levels when visiting the hospital for outpatient appointments or planned admissions.MethodsDatabases such as MEDLINE, PubMed, IEEE Xplore, Web of Science, PsychINFO and Google Scholar were queried for papers published between January 2009 and August 2020 reporting the use of social robots interacting with children in hospital or clinical environments.ResultsA total of 10 studies were located and included. Across these 10 studies, 7 different types of robots were used. Anxiety and distress were found to be reduced in the children who interacted with a social robot.ConclusionsOverall, the evidence suggests that social robots hold a promising role in reducing levels of anxiety or distress in children visiting the hospital. However, research on social robots is at an early stage and requires further studies to strengthen the evidence base.

BackgroundThe use of patient-facing health technologies to manage long-term conditions is increasing; however, children and young people may have particular concerns or needs before deciding to use different health technologies.AimsTo identify children and young people’s reported concerns or needs in relation to using health technologies to self-manage long-term conditions.MethodsA scoping review was conducted. We searched MEDLINE, PsycINFO and CINAHL in February 2019. Searches were limited to papers published between January 2008 and February 2019. We included any health technology used to manage long-term conditions. A thematic synthesis of the data from the included studies was undertaken. We engaged children with long-term conditions (and parents) to support review design, interpretation of findings and development of recommendations.ResultsThirty-eight journal articles were included, describing concerns or needs expressed by n=970 children and/or young people aged 5–18 years. Most included studies were undertaken in high-income countries with children aged 11 years and older. Studies examined concerns with mobile applications (n=14), internet (n=9), social media (n=3), interactive online treatment programmes (n=3), telehealth (n=1), devices (n=3) or a combination (n=5). Children and young people’s main concerns were labelling and identity; accessibility; privacy and reliability; and trustworthiness of information.DiscussionThis review highlights important concerns that children and young people may have before using technology to self-manage their long-term condition. In future, research should involve children and young people throughout the development of technology, from identifying their unmet needs through to design and evaluation of interventions.

It is well established that somatic genomic changes can influence phenotypes in cancer, but the role of adaptive changes in developmental disorders is less well understood. Here we have used next-generation sequencing approaches to identify de novo heterozygous mutations in sterile α motif domain-containing protein 9 (SAMD9, located on chromosome 7q21.2) in 8 children with a multisystem disorder termed MIRAGE syndrome that is characterized by intrauterine growth restriction (IUGR) with gonadal, adrenal, and bone marrow failure, predisposition to infections, and high mortality. These mutations result in gain of function of the growth repressor product SAMD9. Progressive loss of mutated SAMD9 through the development of monosomy 7 (-7), deletions of 7q (7q-), and secondary somatic loss-of-function (nonsense and frameshift) mutations in SAMD9 rescued the growth-restricting effects of mutant SAMD9 proteins in bone marrow and was associated with increased length of survival. However, 2 patients with -7 and 7q- developed myelodysplastic syndrome, most likely due to haploinsufficiency of related 7q21.2 genes. Taken together, these findings provide strong evidence that progressive somatic changes can occur in specific tissues and can subsequently modify disease phenotype and influence survival. Such tissue-specific adaptability may be a more common mechanism modifying the expression of human genetic conditions than is currently recognized.

BackgroundThe use of patient-facing health technologies to manage long-term conditions (LTCs) is increasing; however, children and young people (CYP) may have preferences about health technologies which they interact or engage with, that influence their decision to use these technologies.AimsTo identify CYP’s reported preferences about health technologies to self-manage LTCs.MethodsWe undertook a scoping review, searching MEDLINE, PsycINFO and CINAHL in July 2021. Searches were limited to papers published between January 2015 and July 2021. We included any health technologies used to manage physical and mental LTCs. Qualitative content analysis of study data was undertaken to categorise data into themes and quantitative data were described and visually represented. We engaged CYP with LTCs to support the review design, interpretation of findings and development of recommendations.Results161 journal articles were included, describing preferences of CYP. Most included studies were undertaken in high-income countries. CYP’s main preferences and needs were: design and functionality; privacy and sharing; customisation and personalisation of the technology; and interaction options within the technology.ConclusionsThis review highlights important preferences and needs that CYP may have before using technologies to self-manage their LTC. These should be considered when developing technology for this population. Future research should involve CYP throughout the development of the technologies, from identifying their unmet needs through to final design, development, evaluation and implementation of the intervention.

Adults with type 1 diabetes mellitus (T1DM) are at risk of premature osteoporosis and fractures. The onset of T1DM typically starts during childhood and adolescence. Thus, the effects of DM on the skeleton may be established during this period. Studies in children with T1DM primarily use DXA with conflicting results. We present the first study in adolescents assessing the impact of T1DM on skeletal microstructure and strength using HRpQCT. We recruited 22 patients aged 12 to 16 years with T1DM who were matched by age, gender, and pubertal stage with healthy controls. Paired t tests were applied to assess differences in cortical and trabecular microarchitecture measurements from HRpQCT, and skeletal strength from HRpQCT‐derived microfinite element analysis. Subtotal body, lumbar, and pelvic parameters were assessed using DXA. There was no significant difference in subtotal body, lumbar spine, and pelvic BMD between T1DM and control pairs. However, tibial trabecular thickness was lower (−0.005 mm; 95% CI, −0.01 to −0.001; p = 0.029) and trabecular loading was lower at the distal radius (ratio of the load taken by the trabecular bone in relation to the total load at the distal end (Tb.F/TF) distal: −6.2; 95% CI, −12.4 to −0.03; p = 0.049), and distal and proximal tibia (Tb.F/TF distal: −5.2, 95% CI, −9.2 to −1.2; p = 0.013; and Tb.F/TF proximal: −5.0, 95% CI, −9.8 to −0.1; p = 0.047) in T1DM patients. A subanalysis of radial data of participants with duration of T1DM of at least 2 years and their matched controls demonstrated a reduced trabecular bone number (−0.15, 95% CI, −0.26 to −0.04; p = 0.012), increased trabecular separation (0.041 mm, 95% CI, 0.009–0.072; p = 0.015), an increased trabecular inhomogeneity (0.018, 95% CI, 0.003–0.034; p = 0.021). Regression models demonstrated a reduction in tibial stiffness (−0.877 kN/mm; p = 0.03) and tibial failure load (−0.044 kN; p = 0.03) with higher HbA1C. Thus, in adolescents with T1DM, detrimental changes are seen in tibial and radial microarchitecture and tibial and radial strength before changes in DXA occur and may result from poor diabetic control. © 2020 The Authors.
