Un análisis integrado entre la calidad de vida y las necesidades de apoyo de personas adultas con discapacidad intelectual en Chile / An integrated analysis between the quality of life and the support needs of adults with intellectual disabilities in Chile

El paradigma de apoyos y el de calidad de vida se han transformado en guías fundamentales para los avances en el ámbito de la discapacidad intelectual (DI). Con base en una muestra de 93 personas adultas con DI, se analiza, desde un enfoque cuantitativo no experimental, la relación entre la calidad de vida y las necesidades de apoyo, aplicando la escala INICO-FEAPS y la escala de Intensidad de Apoyos (SIS) para cada constructo. Los principales resultados evidencian que existe una relación fuerte e indirecta entre calidad de vida y necesidades de apoyos, y también la relevancia de analizar dichos resultados desde variables como grado de discapacidad, sexo o nivel socioeconómico. La discusión permite inferir la necesidad de discutir nuevas estrategias en torno a categorías como el grado de discapacidad, la autodeterminación e inclusión social, como elementos facilitadores de la calidad de vida y apoyos desde un enfoque integral que contribuya al desarrollo de estrategias de programas sociales para la población con DI.

The support paradigm and the quality of life paradigm have become fundamental guides for progress in the field of Intellectual Disability (ID). Based on a sample of 93 adults with ID, the relationship between Quality of Life and Support Needs is analyzed from a non-experimental quantitative approach, applying the INICO-FEAPS scale and the SIS Support Intensity scale for each construct. The main results show that there is a strong and indirect relationship between quality of life and support needs, and the relevance of analyzing these results from variables such as the degree of disability, sex or socioeconomic level. The discussion allows us to infer the need to discuss new strategies around categories such as the degree of disability, self-determination and social inclusion, as facilitating elements of quality of life and supporting a comprehensive approach that contributes to the development of social program strategies for the population with ID.

Long-term effects of environmental dynamic lighting on sleep-wake rhythm, mood and behaviour in older adults with intellectual disabilities.

BACKGROUND: Sleep-wake problems and depressive symptoms are common in people with intellectual disabilities (IDs) and are thought to be related to the unstable sleep-wake rhythm in this population. Previously, we showed that after increasing environmental light exposure, mid-sleep and sleep onset advanced, and mood improved over a period of 14 weeks after installing environmental dynamic light installations in the living room of people with IDs. We invited participants of that short-term study to take part in the current study on sleep-wake rhythm, mood and behaviour in older adults with IDs 1 year after installing environmental dynamic light installations in the common living rooms of six group homes. METHODS: A pre-post study was performed from October 2017 to February 2019. We included 45 participants (63.5 ± 8.5 years, 67% female) from six group home facilities who provided data at baseline (9, 4 and 1 weeks prior to installing light installations), short term (3, 7 and 14 weeks after installing light installations) and 1 year (54 weeks after installing light installations). Wrist activity was measured with actigraphy (GENEActiv) to derive the primary outcome of interdaily stability of sleep-wake rhythms as well as sleep estimates. Mood was measured with the Anxiety, Depression and Mood Scale. Behaviour was measured with the Aberrant Behaviour Checklist. RESULTS: One year after installing dynamic lighting, we did not find a change in interdaily stability. Total sleep time decreased (ß = -25.40 min; confidence interval: -10.99, -39.82), and sleep onset time was delayed (ß = 25.63 min; confidence interval: 11.18, 40.08). No effect on mood or behaviour was found. CONCLUSIONS: We did not find a change in sleep-wake rhythm, mood or behaviour in older persons with IDs living in care facilities 1 year after installing the light. We did find evidence for a long-term effect on sleep duration and sleep timing. The results have to be interpreted with care as the current study had a limited number of participants. The need for more research on the long-term effects of enhancing environmental light in ID settings is evident.

PGAP2-Related Hyperphosphatasia-Mental Retardation Syndrome: Report of a Novel Patient, Toward a Broadening of Phenotypic Spectrum and Therapeutic Perspectives.

PGAP2 gene has been known to be the cause of "hyperphosphatasia, mental retardation syndrome-3" (HPMRS3). To date, 14 pathogenic variants in PGAP2 have been identified as the cause of this syndrome in 24 patients described in single-case reports or small clinical series with pan-ethnic distribution. We aim to present a pediatric PGAP2-mutated case, intending to further expand the clinical phenotype of the syndrome and to report our experience on a therapeutic approach to drug-resistant epilepsy.We present the clinical, neuroradiological, and genetic characterization of a Caucasian pediatric subject with biallelic pathogenic variants in the PGAP2 gene revealed by next generation sequencing analysis.We identified a subject who presented with global developmental delay and visual impairment. Brain magnetic resonance imaging showed mild hypoplasia of the inferior cerebellar vermis and corpus callosum and mild white matter reduction. Laboratory investigations detected an increase in alkaline phosphatase. At the age of 13 months, he began to present epileptic focal seizures with impaired awareness, which did not respond to various antiseizure medications. Electroencephalogram (EEG) showed progressive background activity disorganization and multifocal epileptic abnormalities. Treatment with high-dose pyridoxine showed partial benefit, but the persistence of seizures and the lack of EEG amelioration prompted us to introduce ketogenic diet treatment.Our case provides a further phenotypical expansion of HPMRS3 to include developmental and epileptic encephalopathy. Due to the limited number of patients reported so far, the full delineation of the clinical spectrum of HPMRS3 and indications for precision medicine would benefit from the description of new cases and their follow-up evaluations.

Clinicians' experiences of learning to use eye movement desensitisation and reprocessing therapy with people with intellectual disabilities: A qualitative study.

BACKGROUND: Eye Movement Desensitisation and Reprocessing therapy (EMDR) is a NICE recommended treatment for post-traumatic stress disorder within the general population. Ongoing research is now investigating the use of EMDR for individuals with intellectual disability. Alongside quantitative research efforts, it is beneficial to explore the qualitative experience of clinicians adopting EMDR in their practice. The current study interviewed newly trained EMDR therapists working in intellectual disability services. METHOD: Participants (six Clinical Psychologists from an NHS learning disability service) had recently undertaken EMDR training as part of a wider randomised control trial (Trauma-AID). Interviews were qualitatively analysed using thematic analysis. RESULTS: Three themes emerged; learning EMDR, conducting EMDR and external factors, with respect to clinicians' experiences. CONCLUSIONS: Further research is needed to provide guidance and reassurance for clinicians currently using or hoping to use this therapy with people with intellectual disabilities.

A holistic approach to fragile X syndrome integrated guidance for person-centred care.

BACKGROUND: The Fragile X community has expressed a desire for centralised, national guidelines in the form of integrated guidance for Fragile X Syndrome (FXS). METHODS: This article draws on existing literature reviews, primary research and clinical trials on FXS, a Fragile X Society conference workshop and first-hand experience of clinicians who have worked with those living with FXS over many years. RESULTS: The article scopes proposed integrated guidance over the life course, including appendices of symptoms, comorbidities and referral options for FXS and Fragile X Premutation Associated Conditions. CONCLUSION: Integrated guidance would provide an authoritative source for doctors, health professionals, therapists, care workers, social workers, educators, employers, families and those living with FXS, so that a holistic, person-centred approach can be taken across the United Kingdom to garner the best outcomes for those with FXS.

Preferences and experiences of parents/guardians of youth with epilepsy and intellectual disability on reproductive health counseling.

OBJECTIVE: To explore the experiences and preferences of parents/guardians of adolescents and young adults (AYA) of childbearing potential with co-occurring epilepsy and intellectual disability (ID) regarding counseling by neurologists on sexual and reproductive health (SRH) topics such as pregnancy, contraception, menstruation, and folic acid supplementation. METHODS: We conducted semi-structured interviews with parents/guardians of AYAs (12-28 years old) of childbearing potential with co-occurring epilepsy and ID, recruited from a tertiary-care children's hospital. We confirmed the diagnoses of epilepsy and ID with the patient's neurologist and parent/guardian. All degrees of ID (e.g. mild/moderate/severe) were eligible. We audio-recorded and transcribed interviews. Two coders performed qualitative thematic analysis. RESULTS: Twenty-five parents/guardians completed interviews. Themes included: (1) Parents/guardians believe their child to be immune from sexual abuse due to their supervision, yet desire counseling about abuse recognition and prevention, which they also report not occurring (2) A common opinion was that counseling on menstruation was more relevant to their child's life than counseling about pregnancy-related topics (3) Parents/guardians reported a lack of counseling on pregnancy-related topics such as folic acid supplementation and teratogenesis and generally also reported some degree of interest in hearing about these topics from neurologists (4) Parents/guardians also reported a lack of counseling on drug interactions between contraception and ASMs, and were highly interested in learning more about this topic (5) Parents/guardians want neurologists to initiate annual comprehensive SRH counseling at puberty about most topics, but report that they often initiate SRH discussions themselves. CONCLUSION: Parents/guardians of AYAs with epilepsy and ID prefer more frequent, neurologist-initiated, comprehensive conversations surrounding SRH particularly emphasizing menstruation and sexual abuse recognition/prevention. Findings may inform professional and patient education and health systems interventions including development of discussion guides and/or decision aides to improve SRH care for AYAs with epilepsy and ID.

Effectiveness of music therapy in enhancing empathy and emotional recognition in adolescents with intellectual disabilities.

Music therapy has demonstrated efficacy in alleviating symptoms of mental disorders, prompting an investigation into its impact on emotion regulation and empathy levels in adolescents with mild intellectual disabilities. This study involved 120 adolescents diagnosed with mild intellectual disabilities, divided into experimental and control groups. The research evaluated empathy levels and the ability to recognize emotions using photographs and pictograms before and after the experiment. Significant improvements were noted in the experimental group, particularly in empathy towards elderly individuals (p ≤ 0.05), strangers (p ≤ 0.05), cartoon and video characters (p ≤ 0.05), and animals (p ≤ 0.05). Music therapy proved effective in enhancing empathy towards peers (p ≤ 0.01), strangers (p ≤ 0.05), elderly individuals (p ≤ 0.05), animals (p ≤ 0.05), and cartoon characters (p ≤ 0.05). Limited changes were observed in the control group, primarily in the category of empathy towards strangers (p ≤ 0.05). The study suggests music therapy as a recommendable intervention for adolescents with mild intellectual disabilities, enhancing their ability to recognize diverse emotions. The study significantly contributes to the theoretical understanding of music therapy's role in emotional development among adolescents with mild intellectual disabilities, highlighting the nuanced influence of music selection on therapeutic outcomes. The study acknowledges and briefly discusses the ethical considerations involved in conducting research with adolescents, emphasizing the importance of ethical guidelines in working with vulnerable populations.

The views of psychiatrists on proposed changes to the England and Wales Mental Health Act 1983 legislation for people with intellectual disability: A national study.

BACKGROUND: The Draft Mental Health Bill proposes removal of both intellectual disability and autism from Section 3 of the Mental Health Act for England and Wales (MHA). This would lead to people with intellectual disability (PwID) and/or autism could not be detained beyond 28 days, in the absence of diagnosed co-occurring mental illness. AIM: To obtain views of psychiatrists working with PwID in England and Wales regarding the proposed MHA changes. This study focusses specifically on the impact on PwID. METHODS: A cross-sectional online mixed methodology survey of Likert and free-text response questions was developed, to ascertain perceptions of proposed legislative changes to the MHA. A non-discriminatory exponential snowballing technique leading to non-probability sampling was used to disseminate the survey. Quantitative data was analysed using descriptive statistics, Mann-Whitney and Fisher's exact tests. Thematic analysis was conducted on free text responses. RESULTS: A total of 82 psychiatrists (33%) from approximately 250 eligible completed the survey. Nearly two-thirds (64%) reported good awareness of the proposed changes, with over half (55%) reporting disagreement with the changes. Psychiatrists working in inpatient settings for PwID reported increased awareness of the changes, less agreement with the reforms, and increased expectations of the reforms having negative unintended consequences, compared to their peers working exclusively in the community. Consultants reported greater disagreement with the changes compared to their non-consultant peers. Qualitative analysis identified five main themes: impact on diagnosis and treatment, seeking alternative options, introducing inequities, resources, and meeting holistic care goals through the Care, Education and Treatment Reviews (CETR) process. CONCLUSION: Psychiatrists working with PwID report widespread disagreement with the proposed changes to the MHA for PwID, with greater levels of disagreement among those working in inpatient services. Caution with respect to the proposed changes, and monitoring of the impact of the changes if implemented, is advised.

Smoking cessation interventions for U.S. adults with disabilities: A systematic review.

INTRODUCTION: People with disabilities disproportionately use tobacco products. However, little is known about cessation interventions tailored for people with disabilities. The objective of this study was to conduct a systematic review of smoking cessation interventions for adults with disabilities. METHODS: Six electronic databases (Cochrane, CINAHL Plus [EBSCOhost], Embase [Ovid], Medline [Ovid], PsycINFO [Ovid], and Web of Science) were searched to identify eligible interventions for people with disabilities (e.g., vision, hearing, mobility, communication, cognition, self-care) through July 2023. Two independent coders evaluated the records and extracted data from studies that met inclusion criteria. Qualitative synthesis was conducted on the included studies in 2023. RESULTS: One randomized controlled trial and one nonrandomized study met the inclusion criteria. Both studies used mindfulness-based procedures to reduce cigarette use in adults with mild intellectual disability. The outcome was defined as self-reported cigarette use at follow-up, which ranged from 1 year to 3 years. Limited information was provided on how the interventions were tailored to meet the unique needs of people with disabilities in either study. CONCLUSION: Two interventions conducted in adults with mild intellectual disability showed promising results using mindfulness-based procedures; however, the studies did not address barriers reported by people with disabilities, nor tailor the interventions to meet the needs of the target population. Research is needed to address tobacco use disparities among people with a range of disabilities. Current cessation interventions would be enhanced by integrating disability identifiers alongside other demographic information in future studies and reporting subgroup analyses in adults with disabilities.

The Effect of Vitamin K2 Supplementation on PIVKA-II Levels in Patients with Severe Motor and Intellectual Disabilities Undergoing Long-Term Tube Feeding.

Nutritional support is essential for patients with severe motor and intellectual disabilities (SMID) to ensure the smooth provision of medical care. These patients often require long-term tube feeding with enteral formulas, potentially leading to deficiencies in vitamins and trace elements. Additionally, frequent antibiotic use for infections often disrupts gut microbiota, inhibiting vitamin K2 production by intestinal bacteria. We assessed the serum protein induced by vitamin K absence or antagonists-II (PIVKA-II) and undercarboxylated osteocalcin (ucOC) levels to assess the vitamin K status in 20 patients with SMID (median age: 44.1 years, 11 men and 9 women) undergoing long-term tube feeding for durations ranging from 3 to 31 years. Thirteen (65%) and nine (45%) patients had elevated PIVKA-II (<40 mAU/mL) and serum ucOC levels (reference value < 4.50 ng/mL), respectively. Dietary vitamin K1 intake did not differ between patients with and without elevated PIVKA-II levels. Vitamin K2 supplementation for 3 months decreased serum PIVKA-II levels near those within the reference range. Approximately half of the patients with SMID on tube feeding had subclinical vitamin K deficiency. Further studies are needed to ascertain if long-term vitamin K2 supplementation effectively prevents vitamin K deficiency-induced hypercoagulation, osteoporosis, and vascular calcification in patients with SMID.

Hirschsprung disease.

Hirschsprung disease (HSCR) is a rare congenital intestinal disease that occurs in 1 in 5,000 live births. HSCR is characterized by the absence of ganglion cells in the myenteric and submucosal plexuses of the intestine. Most patients present during the neonatal period with the first meconium passage delayed beyond 24 h, abdominal distension and vomiting. Syndromes associated with HSCR include trisomy 21, Mowat-Wilson syndrome, congenital central hypoventilation syndrome, Shah-Waardenburg syndrome and cartilage-hair hypoplasia. Multiple putative genes are involved in familial and isolated HSCR, of which the most common are the RET proto-oncogene and EDNRB. Diagnosis consists of visualization of a transition zone on contrast enema and confirmation via rectal biopsy. HSCR is typically managed by surgical removal of the aganglionic bowel and reconstruction of the intestinal tract by connecting the normally innervated bowel down to the anus while preserving normal sphincter function. Several procedures, namely Swenson, Soave and Duhamel procedures, can be undertaken and may include a laparoscopically assisted approach. Short-term and long-term comorbidities include persistent obstructive symptoms, enterocolitis and soiling. Continued research and innovation to better understand disease mechanisms holds promise for developing novel techniques for diagnosis and therapy, and improving outcomes in patients.

Prenatal Diagnosis and Molecular Cytogenetic Analyses of a de novo Deletion on Chromosome 4p16.3p15.33.

Wolf-Hirschhorn syndrome (WHS) (OMIM 194190) is a contiguous gene syndrome with an estimated prevalence of around 1 in 50,000 births. The syndrome is caused by the deletion of a critical region (Wolf-Hirschhorn Syndrome Critical region-WHSCR) on chromosome 4p16.3. Its core features are typical facial gestalt, growth retardation, intellectual disability, developmental delay, and seizures. Prenatal diagnosis of WHS helps clinicians and parents make informed decisions about pregnancy management. In this research, a 31-year-old woman (gravida 1, para 0) underwent amniocentesis at 18 weeks gestation because of the short nasal bone of the fetus on prenatal ultrasound. Chromosomal microarray analysis (CMA) on uncultured amniocytes revealed a de novo 11.36-Mb deletion on chromosome 4p16.3p15.33, spanning from position 40 000 to 11 400 000 (hg19). After genetic counselling and being informed of the unfavorable prognosis, the parents decided to terminate the pregnancy. We provide a detailed description of a de novo 11.36-Mb deletion on chromosome 4p16.3p15.33 (Wolf-Hirschhorn syndrome). CMA has more advantages than karyotype analysis in detecting chromosomal microdeletions/microduplications. A combination of karyotype analysis, CMA, prenatal ultrasound, and genetic counseling is helpful for the prenatal diagnosis of chromosomal deletions/duplications.

[Exploration of acupuncture treatment for insomnia induced by mental retardation: based on "trinity theory of shaoyang, sanjiao and haishi"].

Insomnia induced by mental retardation is related to the synergistic dysfunction of "shaoyang, sanjiao and haishi (the period of the day from 9 pm to 11 pm) " in pathogenesis. Based on "trinity theory of shaoyang, sanjiao and haishi ", the acupoints of hand and food shaoyang meridians on the head and face (Fengchi [GB 20], Sizhukong [TE 23] and Jiaosun [TE 20]) and those on the four limbs (Sanyangluo [TE 8], Zhongzhu [TE 3], Qiuxu [GB 40] and Xiaxi [GB 43]) are selected to regulate the pivot function of shaoyang. Front-mu and back-shu points (Sanjiaoshu [BL 22], Danzhong [CV 17] and Tianshu [ST 5]), as well as auricular points (Gan [CO12], Dan [CO11] and Sanjiao [CO17]) are chosen to promote qi circulation of shaoyang and sanjiao meridians. In association with the relevant knowledge of time acupuncture at haishi, the circadian rhythm of sleep is set up and the appropriate sleep pattern is developed.

The impact of mindfulness interventions for staff on the care, treatment, and experiences of people with intellectual disabilities: A systematic review.

BACKGROUND: Mindfulness interventions have been shown to ameliorate stress in support staff working with people with intellectual disabilities. This review aimed to explore what impact mindfulness interventions for staff have on their care and support behaviours, and on the experiences of people with intellectual disabilities receiving support. METHOD: A systematic search of PsycINFO, Web of Science, ASSIA, and PubMed identified nine studies meeting the inclusion criteria. Outcomes were collated and a quality assessment tool was used to inform the critical analysis of the studies. RESULTS: Despite identified methodological issues, positive results were consistently reported. These included reduced use of restrictive practices by staff, increased positive interactions between staff and people with intellectual disabilities, and reduced aggression displayed by people with intellectual disabilities. CONCLUSIONS: Further research in this area is required; however, this review supports the benefits of mindfulness on staff behaviour and the quality of life of people with intellectual disabilities.

Age-related physical health of older autistic adults in Sweden: a longitudinal, retrospective, population-based cohort study.

BACKGROUND: Research of health outcomes in older autistic adults (≥45 years) is concerningly scarce, and little is known about whether intellectual disability and sex affect the health outcomes of this population. The aim of this study was to investigate the association between autism and physical health conditions in older adults and to examine these associations by intellectual disability and sex. METHODS: We conducted a longitudinal, retrospective, population-based cohort study of the Swedish population born between Jan 1, 1932, and Dec 31, 1967, using linked data from the nationwide Total Population Register and the National Patient Register. We excluded individuals who died or emigrated before the age of 45 years, or with any chromosomal abnormalities. Follow-up started at age 45 years for all individuals, and ended at emigration, death, or Dec 31, 2013 (the latest date of available follow-up), whichever was soonest. Diagnoses of autism, intellectual disability, 39 age-related physical conditions, and five types of injury (outcomes) were obtained from the National Patient Register. For each outcome, we calculated 25-year cumulative incidence and used Cox models to estimate hazard ratios (HRs). All analyses were repeated separately by intellectual disability and sex. FINDINGS: Of 4 200 887 older adults (2 063 718 women [49·1%] and 2 137 169 men [50·9%]) in the study cohort, 5291 (0·1%) had a diagnosis of autism recorded in the National Patient Register. Older autistic adults (median follow-up 8·4 years [IQR 4·2-14·6]) had higher cumulative incidence and HRs of various physical conditions and injuries than their non-autistic counterparts (median follow-up 16·4 years [8·2-24·4]). In autistic individuals, the highest cumulative incidence was observed for bodily injuries (50·0% [95% CI 47·6-52·4]). Conditions that autistic adults were at higher risk of than were non-autistic adults included heart failure (HR 1·89 [95% CI 1·61-2·22]), cystitis (2·03 [1·66-2·49]), glucose dysregulation (2·96 [2·04-4·29]), iron deficiency anaemia (3·12 [2·65-3·68]), poisoning (4·63 [4·13-5·18]), and self-harm (7·08 [6·24-8·03]). These increased risks mainly persisted regardless of intellectual disability or sex. INTERPRETATION: Our data indicate that older autistic adults are at substantially increased risk of age-related physical conditions and injuries compared with non-autistic adults. These findings highlight the need for collaborative efforts from researchers, health services, and policy makers to provide older autistic individuals with the necessary support to attain healthy longevity and a high quality of life.

Awareness of social care needs in people with epilepsy and intellectual disability.

BACKGROUND: Nearly a quarter of people with intellectual disability (ID) have epilepsy with large numbers experiencing drug-resistant epilepsy, and premature mortality. To mitigate epilepsy risks the environment and social care needs, particularly in professional care settings, need to be met. PURPOSE: To compare professional care groups as regards their subjective confidence and perceived responsibility when managing the need of people with ID and epilepsy. METHOD: A multi-agency expert panel developed a questionnaire with embedded case vignettes with quantitative and qualitative elements to understand training and confidence in the health and social determinants of people with ID and epilepsy. The cross-sectional survey was disseminated amongst health and social care professionals working with people with ID in the UK using an exponential non-discriminative snow-balling methodology. Group comparisons were undertaken using suitable statistical tests including Fisher's exact, Kruskal-Wallis, and Mann-Whitney. Bonferroni correction was applied to significant (p < 0.05) results. Content analysis was conducted and relevant categories and themes were identified. RESULTS: Social and health professionals (n = 54) rated their confidence to manage the needs of people with ID and epilepsy equally. Health professionals showed better awareness (p < 0.001) of the findings/recommendations of the latest evidence on premature deaths and identifying and managing epilepsy-related risks, including the relevance of nocturnal monitoring. The content analysis highlighted the need for clearer roles, improved care pathways, better epilepsy-specific knowledge, increased resources, and better multi-disciplinary work. CONCLUSIONS: A gap exists between health and social care professionals in awareness of epilepsy needs for people with ID, requiring essential training and national pathways.

Clinical features and magnesium levels: Novel insights in 15q11.2 BP1-BP2 copy number variants.

BACKGROUND: Investigating copy number variations (CNVs) such as microdeletions or microduplications can significantly contribute to discover the aetiology of neurodevelopmental disorders. 15q11.2 genomic region, including NIPA1 and NIPA2 genes, contains a recurrent but rare CNV, flanked by the break points BP1 and BP2. Both BP1-BP2 microdeletion and microduplication have been associated with intellectual disability (ID), neuropsychiatric/behavioural disturbances and mild clinical features, even if with incomplete penetrance and variable expressivity. The pathogenic role of this CNV is quite unclear though. Unknown variants in other DNA regions and parent-of-origin effect (POE) are some of the mechanisms that have been proposed as an explanation of the wide phenotypic variability. As NIPA1 and NIPA2 encode for proteins that mediate magnesium (Mg2+ ) metabolism, it has been suggested that urinary Mg2+ levels could potentially represent informative and affordable biomarkers for a rapid screening of 15q11.2 duplications or deletions. Furthermore, magnesium supplementation has been proposed as possible therapeutic strategy. METHODS: Thirty one children with ID and/or other neurodevelopmental disorders carrying either a duplication or a deletion in 15q11.2 BP1-BP2 region have been recruited. When available, blood samples from parents have been analysed to identify the CNV origin. All participants underwent family and medical data collection, physical examination and neuropsychiatric assessment. Electroencephalogram (EEG) and brain magnetic resonance imaging (MRI) scan were performed in 15 children. In addition, 11 families agreed to participate to the assessment of blood and urinary Mg2+ levels. RESULTS: We observed a highly variable phenotypic spectrum of developmental issues encompassing ID in most subjects as well as a variety of behavioural disorders such as autism and attention-deficit disorder/attention-deficit hyperactivity disorder. Dysmorphic traits and malformations were detected only in a minority of the participants, and no clear association with growth anomalies was found. Abnormal brain MRI and/or EEG were reported respectively in 64% and 92% of the subjects. Inheritance assessment highlighted an excess of duplication of maternal origin, while cardiac alterations were detected only in children with 15q11.2 CNV inherited from the father. We found great variability in Mg2+ urinary values, without correlation with 15q11.2 copy numbers. However, the variance of urinary Mg2+ levels largely increases in individuals with 15q11.2 deletion/duplication. CONCLUSIONS: This study provides further evidence that 15q11.2 BP1-BP2 CNV is associated with a broad spectrum of neurodevelopmental disorders and POE might be an explanation for clinical variability. However, some issues may question the real impact of 15q11.2 CNV on the phenotype in the carriers: DNA sequencing could be useful to exclude other pathogenic gene mutations. Our results do not support the possibility that urinary Mg2+ levels can be used as biomarkers to screen children with neurodevelopmental disorders for 15q11.2 duplication/deletion. However, there are evidences of correlations between 15q11.2 BP1-BP2 CNV and Mg2+ metabolism and future studies may pave the way to new therapeutic options.

[Transcutaneous electrical acupoint stimulation based on electro-oculogram signal regulation for children with mental retardation: a randomized controlled trial].

OBJECTIVE: To observe the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) at Changqiang (GV 1) based on the modulation of electro-oculogram (EOG) signal for children with mental retardation, and explore the evaluation effect of the goal attainment scale (GAS) in children with mental retardation. METHODS: Sixty children with mental retardation were randomly divided into a treatment group and a control group, with 30 cases in each one. The children in the control group were treated with conventional rehabilitation, 5 times a week. On the basis of the control group, TEAS at Changqiang (GV 1) under the modulation of EOG signal was adopted in the treatment group. When the similarity between the collected EOG signal and the template was within the range of EOG threshold, one electric stimulation was triggered at Changqiang (GV 1) for 20 s (continuous wave, 70-100 Hz in frequency, 0.1-0.2 ms in pulse width), lasting 30 min in each treatment, the intervention was given twice a week. One course of treatment was composed of 4 weeks, and 3 courses were required in total in the two groups. The infant-junior high school student's social living ability scale (S-M) and GAS were scored and compared before and after treatment in the two groups. RESULTS: After treatment, the scores of self-living ability in the treatment group and communication ability in the control group were higher than those before treatment (P<0.01, P<0.05). The scores of collective activity and motor ability in the treatment group were higher than those in the control group (P<0.05). After treatment, GAS scores were higher than before treatment in both groups (P<0.001), and the score in the treatment group was higher than the control group (P<0.05). CONCLUSION: TEAS under the modulation of EOG signal is conductive to improving the collective, motor and self-living abilities of the children with mental retardation and promoting children's individual goals. Compared with the standard score of S-M, the T value of GAS can better reflect the subtle progress of individual.

Mortality risk in adults with intellectual disabilities and epilepsy: an England and Wales case-control study.

BACKGROUND: People with epilepsy (PWE) and people with intellectual disabilities (ID) both live shorter lives than the general population and both conditions increase the risk of death further. We aimed to measure associations between certain risk factors for death in PWE and ID. METHODS: A retrospective case-control study was conducted in ten regions in England and Wales. Data were collected on PWE registered with secondary care ID and neurology services between 2017 and 2021. Prevalence rates of neurodevelopmental, psychiatric and medical diagnoses, seizure frequency, psychotropic and antiseizure medications (ASM) prescribed, and health activity (epilepsy reviews/risk assessments/care plans/compliance etc.) recorded were compared between the two groups. RESULTS: 190 PWE and ID who died were compared with 910 living controls. People who died were less likely to have had an epilepsy risk assessment but had a greater prevalence of genetic conditions, older age, poor physical health, generalized tonic-clonic seizures, polypharmacy (not ASMs) and antipsychotic use. The multivariable logistic regression for risk of epilepsy-related death identified that age over 50, medical condition prevalence, antipsychotic medication use and the lack of an epilepsy review in the last 12 months as associated with increased risk of death. Reviews by psychiatrists in ID services was associated with a 72% reduction in the odds of death compared neurology services. CONCLUSIONS: Polypharmacy and use of antipsychotics may be associated with death but not ASMs. Greater and closer monitoring by creating capable health communities may reduce the risk of death. ID services maybe more likely to provide this holistic approach.
