Filter by:Transcranial direct current stimulation (tDCS) is a method which enables noninvasive electrical stimulation of the cortex via electrodes placed on the subject's skull. High definition tDCS (HD-tDCS) allows for precise generation of electrical fields over selected cortical areas using multiple electrodes. The purpose of this pilot trial is to study feasibility, tolerability, and safety of HD-tDCS administered daily for a total of 20 sessions in healthy adults and 5-10 year old children with Down syndrome. PRIMARY OBJECTIVES Part I: To assess feasibility and tolerability of HD-tDCS, administered up to 5 days per week for a total of 20 sessions in healthy adult subjects; Part II: After review of the safety data for Part I is completed and reviewed by the Data Safety Monitoring Committee and IRB, Part II will be initiated. To assess feasibility and tolerability of HD-tDCS, administered up to 5 days per week for a total of 20 sessions in adult subjects with Down Syndrome.
The aim of this study is to assess the suitability of selected scales (floor/ceiling effects, variability, test-retest reliability) to measure cognitive function in children with Down syndrome over 6 months, and to evaluate the influence of covariates such as age, gender or language on these neurocognitive scales.
This study is a single center, randomized, double-blind, placebo-controlled, cross-over pilot study designed to assess the safety of intranasally (IN) delivered glulisine versus placebo in patients with DS. Subjects will be randomized into this cross-over study and within subject comparisons conducted between single treatment of intranasal insulin glulisine and single treatment of intranasal placebo. All subjects will also receive a single treatment of placebo prior to randomization to ensure adherence to study procedures.
To evaluate the suitability (i.e. number of tests completed and number of participants completing the tests, variance estimate of baseline and of the change from baseline values) of neurocognitive tests and functioning scales in view of their use in future multicenter, multinational clinical efficacy trials testing a putative cognitive enhancer for individuals with Down syndrome aged 6-30.
To obtain whole blood specimens from pregnant subjects to be used for research and development and clinical validation studies of prenatal assays.
The purpose of this study is to evaluate the performance of non invasive screening in a population of pregnant women with and without in vitro fertilisation (IVF) concomitantly to regular first trimester trisomy 21 (T21) screening using maternal age, nucal fold measurement and serum screening.
This study plans to learn more about Down syndrome. The investigators think there is a different level of the AIRE gene in individuals with Down syndrome. The investigators think that the AIRE gene level can provide more insight about depressed immune cell function in individuals with Down syndrome. Patients are being asked to be in this research study because the investigators want to see if their blood contains more of less of the AIRE gene.
This multi-center prospective observational study is designed to track birth outcomes and perinatal correlates to the Panorama prenatal screening test in the general population among ten thousand women who present clinically and elect Panorama microdeletion and aneuploidy screening as part of their routine care. The primary objective is to evaluate the performance of Single Nucleotide Polymorphism (SNP)-based Non Invasive Prenatal Testing (NIPT) for 22q11.2 microdeletion (DiGeorge syndrome) in this large cohort of pregnant women. This will be done by performing a review of perinatal medical records and obtaining biospecimens after birth to perform genetic diagnostic testing for 22q11.2 deletion. Results from the follow-up specimens will be compared to those obtained by the Panorama screening test to determine test performance. Specific test performance parameters will include: PPV, specificity, and sensitivity.
The main aims of the present project include 1) to study the longitudinal effects of whole-body vibratory exercise on bone metabolism in adolescents with and without DS and 2) to evaluate whether a low frequency vibratory training program consisting of 3 sessions per week for 9 months (each vibratory session last approximately 10 minutes and includes 5-6 bouts of 1 min with 1 min rest between bouts) can improve bone development in these populations. Finally, and additional aim of the project is 3) to determine how long these effects may last after the end of the intervention.
Obstructive sleep apnea (OSA) affects up to 1% of the general pediatric population and is associated with adverse behavior and quality of life, as well as long term cardiopulmonary system complications. Trisomy 21 (Down Syndrome) is the most common chromosomal disorder, with a incidence of approximately 1 per 660-800 births. Patients with Down Syndrome have a higher incidence of OSA than the general pediatric population, with rates of 30-60%, resulting in increased morbidity and decreased quality of life for affected individuals. In children, adenotonsillectomy (T&A) is often a contributing factor to OSA, and adenotonsillectomy is a first line treatment. Children with Down Syndrome often undergo T&A for obstructive sleep apnea, however 30-50% will have persistent obstructive sleep patterns requiring continuous positive pressure airway support (CPAP) or tracheotomy. Persistent obstruction is attributed to anatomic and physiologic differences in this population, including reduced muscular tone, macroglossia, maxillary hypoplasia, and lingual tonsil hypertrophy. This pilot study is designed to determine if the Inspire® Upper Airway Simulation System, Model 3024 IPG, and any subsequent iteration thereof that are approved under P130008 for the treatment of obstructive sleep apnea, which has already been approved for use in adults with OSA, can be safely implanted and used in adolescents and young adults with Down Syndrome.
