Based on available literature and our own preliminary research, the researchers have concluded that persons with Down syndrome (DS) exhibit difficulties in utilizing the specific spatial abilities of mental rotation and perspective taking and performing complex spatial tasks such as wayfinding and environmental learning. A weakness in spatial abilities may have many direct applications to daily life, ranging from activities such as tying shoes to using hand tools and navigating the environment. Spatial abilities also serve as a cognitive foundation for many other complex skills such as solving mathematical problems and using spatial language for giving and receiving directions. Moreover, spatial abilities are used in a variety of specialty jobs such as grocery stocking, packaging, and assembling, which are among the most commonly reported jobs for adults with DS. Hence, a new focus on spatial ability and its modifiability in persons with DS is clearly warranted. The primary goal of the research proposed in this application is to evaluate the malleability of mental rotation and perspective taking in people with DS through providing intentional experience with numerous spatial activities. Two groups of participants will be tested over the course of the project: adolescents and young adults with DS and typically developing (TD) children. Following an initial evaluation of performance on the two abilities, participants will receive up to eight sessions of spatial activity experience utilizing puzzle construction, block building, and computer search tasks. Following the experience sessions, spatial abilities of participants will be re-evaluated. These data will be used to investigate two specific aims. First, the researchers investigate whether spatial abilities of persons with DS can be modified by experience with spatial activities. Second, the researchers investigate whether the degree of modification observed for persons with DS can reduce performance differences between them and TD children. The researchers also consider whether performance on the PPVT, Raven's matrices, and Chronological Age are associated with any benefits from spatial ability experience.
In patients with endodontically treated molar teeth indicated for endocrown, will the fiber reinforced FRC base and bonded CAD/CAM resin composite endocrowns restorations have a similar clinical performance to the conventional lithium disilicate endocrown over one year?
Intractable symptoms of Meniere's disease will be treated with intratympanic steroids. At the same time intratympanic dexamethasone will be used to rescue hearing
The overarching objective for the Supporting Health Relationships (SHR) program is to create and sustain families in the Bronx by improving relationship skills, improving parenting skills, and improving parental financial support for children. The investigator's local evaluation addresses a research question about the effectiveness of delivering the SHR curriculum virtually: To what extent do couples show improvements in engagement, skills learning, and relationship quality outcomes when receiving the curriculum over Zoom?

This randomized clinical trial (RCT) is evaluating the usefulness of combining MyoMo robotic orthosis with visual and haptic feedback in ameliorating wrist/hand/UE movement capability, and increasing ADL and quality of life in people with acute SCI.
This study is a prospective, multi-center, real world, observational study, which aims at evaluating the intermediate and long-term efficacy of endovascular treatment for TASC C&D aortoiliac occlusive disease .It is estimated that 800 subjects diagnosed with TASC C&D aortoiliac occlusive disease and receive endovascular treatments will be enrolled in nine centers from April 2021 to June 2027 nation-widely. All the subjects will be under follow-up for 60 months. There is no restriction on the endovascular techniques. The primary outcomes covers freedom from TLR at 60 months.
This study is about the application of needle-free injection device in GDM patients in order to observe the variation of blood glucose and patients' experience compared to the traditional insulin pen injection. To provide evidence for the application of needle-free syringe injection in GDM patients.
The aims of this case-control, non-randomized study including patients with post-COVID-19 persisting symptoms are 1) to establish the large blood biobank, 2) to examine levels of circulating inflammatory biomarkers and different classes of non-coding RNAs (ncRNA), such as selected circRNAs and miRNAs, in plasma and serum samples collected from patients with post- COVID-19, 3) to test the levels of cfDNA in plasma and serum, 4) to define correlation between ncRNAs and cf-DNA with persistent clinical symptoms, and type of symptoms, and 5) to investigate diagnostic and prognostic performances of these circulating biomarkers. Study design. This is a prospective registry including biobank.
Background: Severe aortic valve stenosis (AS) is the commonest valve disease. Aortic valve replacement (AVR) is primarily indicated when symptoms occur and/or when there is a drop in left ventricular ejection fraction. However, irreversible myocardial damage, such as replacement fibrosis, leads to increased morbidity and mortality despite treatment. Improved patient selection and timely treatment is thus warranted. T1 mapping, a non-invasive method to quantify myocardial fibrosis by cardiac magnetic resonance (CMR), could be a marker to guide treatment. Aims: To investigate the change of myocardial fibrosis* in AS patients following AVR and if these changes are associated with disease and/or procedural characteristics. Methods: This is an observational clinical trial. Approximately 60 patients with severe AS planned to undergo AVR (either surgical or transcatheter) at Rigshospitalet, Denmark will be included. Participants will undergo CMR before surgery and at a 1-year follow-up. Other assessments include clinical evaluation and blood sampling. The primary end-point is change in T1 values after AVR. Hypotheses and perspectives: The investigators hypothesize that (1) myocardial fibrosis* will regress in patients undergoing AVR as a group, (2) the degree of myocardial fibrosis is positively correlated with the degree of symptoms, (3) the regression of myocardial fibrosis is greater in patients undergoing TAVR compared to SAVR, and (4) the regression of myocardial fibrosis is greater in patients with tricuspid aortic stenosis compared to bicuspid aortic stenosis. Ultimately, T1 mapping is a potential marker for improved patient selection for the timing of AVR. * Estimated by T1 mapping
