Caregiver support, burden, and long-term planning among caregivers of individuals with intellectual and developmental disabilities: A cross-sectional study.

BACKGROUND: Long-term care planning (LTCP) is critical for individuals with intellectual/developmental disabilities. Objectives of this study were to investigate progression through LTCP, and associations between social support and: (1) LTCP and (2) burden among family caregivers. METHODS: A cross-sectional survey was distributed to caregivers of individuals with intellectual/developmental disabilities in NY, OH, PA, and TX, exploring demographics, supports, burden, and LTCP behaviours. Bivariate and linear multiple regression analyses were used to investigate study objectives. RESULTS: Caregivers (n = 405) were predominantly parents, female, non-Hispanic, and in the 'learning to plan' stage of LTCP. Caregiver-identified social support was associated with further progression in LTCP (p = .020) and lower caregiver burden (p < .001). CONCLUSION: Social support was associated with further progression in LTCP, and associated with less burden, however fewer than 40% of caregivers reported having social support. Ongoing exploration of emotional/social needs of caregivers is necessary to better support these families.

Unexplained regression in Down syndrome: Management of 51 patients in an international patient database.

Research to guide clinicians in the management of the devastating regression which can affect adolescents and young adults with Down syndrome is limited. A multi-site, international, longitudinal cohort of individuals with a clinical diagnosis of Unexplained Regression in Down syndrome (URDS) was collated through seven Down syndrome clinics. Tiered medical evaluation, a 28-item core symptom list, and interim management are described naturalistically. Improvement-defined by the percentage of baseline function on a Parent-reported Functional Score, overall improvement in symptoms on a Clinician-administered Functional Assessment, or report of management type being associated with improvement-was analyzed. Improvement rates using ECT, IVIG, and others were compared. Across seven clinics, 51 patients with URDS had regression at age 17.6 years, on average, and showed an average 14.1 out of 28 symptoms. Longitudinal improvement in function was achieved in many patients and the medical management, types of treatment, and their impact on function are described. Management with intravenous immunoglobulin (IVIG) was significantly associated with higher rate of improvement in symptoms at the next visit (p = 0.001). Our longitudinal data demonstrates that URDS is treatable, with various forms of clinical management and has a variable course. The data suggests that IVIG may be an effective treatment in some individuals. Our description of the management approaches used in this cohort lays the groundwork for future research, such as development of standardized objective outcome measure and creation of a clinical practice guideline for URDS.

Identifying key components of a web-based long term care planning intervention for family caregivers of individuals with intellectual/developmental disabilities.

BACKGROUND: Few family caregivers of individuals with intellectual or developmental disabilities develop long-term care (LTC) plans for their relative. Web-based interventions promoting LTC planning have potential for widespread adoption into clinical practice. METHODS: We conducted focus groups with 49 primary caregivers of individuals with intellectual or developmental disabilities in NY, PA, OH, DE, and TX to identify barriers and facilitators of LTC planning, review existing tools, and identify critical features for web-based LTC planning interventions. Participants also answered questions on demographic characteristics and functional status. RESULTS: NVivo qualitative analysis software was used to analyse focus groups using a grounded theory approach. Caregivers identified web tool accessibility and topics such as finances, housing, and government benefits as critical. Caregivers also described desired features for a LTC planning tool. CONCLUSIONS: This study identified desired characteristics of web-based LTC planning tools and ways in which existing web-based interventions might be adapted or enhanced.

The Prevalence of OSA Among an Adult Population With Down Syndrome Referred to a Medical Clinic.

Obstructive sleep apnea (OSA) is a common sleep disorder affecting approximately 16% of adults (24% of men and 9% of women), and, if untreated, it can cause significant complications ( Young, 2009 ). This study evaluates 56 adult patients with Down syndrome and analyzed retrospective data to determine the: (1) prevalence of OSA, (2) severity of OSA, and (3) association between body mass index (BMI) and OSA. Of those participants that had polysomnography (PSG) testing available, 82.1% were diagnosed with OSA, divided by severity into mild (45.7%), moderate (15.2%), and severe (39.1%) levels. Because of the high prevalence of OSA among our study population, we recommend that all adults with DS be screened for OSA with PSG.

Identification of a schizophrenia-associated functional noncoding variant in NOS1AP.

OBJECTIVE: The authors previously demonstrated significant association between markers within NOS1AP and schizophrenia in a set of Canadian families of European descent, as well as significantly increased expression in schizophrenia of NOS1AP in unrelated postmortem samples from the dorsolateral prefrontal cortex. In this study the authors sought to apply novel statistical methods and conduct additional biological experiments to isolate at least one risk allele within NOS1AP. METHOD: Using the posterior probability of linkage disequilibrium (PPLD) to measure the probability that a single nucleotide polymorphism (SNP) is in linkage disequilibrium with schizophrenia, the authors evaluated 60 SNPs from NOS1AP in 24 Canadian families demonstrating linkage and association to this region. SNPs exhibiting strong evidence of linkage disequilibrium were tested for regulatory function by luciferase reporter assay. Two human neural cell lines (SK-N-MC and PFSK-1) were transfected with a vector containing each allelic variant of the SNP, the NOS1AP promoter, and a luciferase gene. Alleles altering expression were further assessed for binding of nuclear proteins by electrophoretic mobility shift assay. RESULTS: Three SNPs produced PPLDs >40%. One of them, rs12742393, demonstrated significant allelic expression differences in both cell lines tested. The allelic variation at this SNP altered the affinity of nuclear protein binding to this region of DNA. CONCLUSIONS: The A allele of rs12742393 appears to be a risk allele associated with schizophrenia that acts by enhancing transcription factor binding and increasing gene expression.
