All Clinical Trials

The goal of this study is to conduct a prospective, longitudinal assessment of the natural clinical progression of children and adults with Synaptotagmin1-Associated Neurodevelopmental Disorder also known as Baker Gordon Syndrome (BAGOS). This will be performed by acquiring baseline measurements and developing effective outcome measures and diagnostic tools for the disorder, to prepare the healthcare system for future clinical trials.

Patients undergoing either an autologous or allogeneic hematopoietic stem cell transplant (HSCT) and receiving preparative chemotherapy experience a considerable amount of chemotherapy-induced nausea and vomiting (CINV). Current strategies at reducing CINV in this patient population are suboptimal due to lack of efficacy and supportive evidence, potential for increased adverse events, and drug-drug and drug-disease contraindications.

The purpose of the study is to evaluate whether non-invasive stimulation over the spinal cord at the neck and/or lower back can improve walking function for people with neurologic conditions. Spinal stimulation has been used extensively for individuals with spinal cord injury, and has demonstrated improvements in function. This study will extend this work to other neurologic conditions, such as cerebral palsy and stroke, that also demonstrate similar impairments as spinal cord injury. The primary aims of this study are to: Aim 1: Evaluate impact of spinal stimulation on spasticity and locomotor function. Aim 2: Investigate participant perceptions of spinal stimulation. The investigators will be using a cross-over design study to compare intensive training only to intensive training combined with spinal stimulation. After an initial baseline period of up to 4 weeks (Phase I). Participants will have their first intervention phase of the study (Phase II). This will involve either intensive training only (Condition A) or intensive training combined with spinal stimulation (Condition B). This will be followed by a washout period with no intervention (Phase III) and then the second intervention phase (Phase IV). The second intervention phase will involve either Condition A or Condition B, whichever the participants did not received during Phase II. Phases II-IV will each last up to 8 weeks. After the intervention period is complete, the participant will be asked to come for follow-up visits up to 3 months after the intervention phases are completed (Phase V). Read Less

The purpose of this program is to allow the use of domperidone in children from 12 to 21 years of age with symptoms related to motility disorders and Gastroesophageal reflux disease (GERD) who have failed all the standard treatments for their condition. Read Less

Between 39-67% of the 294,000 Americans who have a SCI suffer from long-term debilitating neuropathic pain, interfering with rehabilitation, general activity, mobility, mood, sleep, and quality of life. Pain can hinder any potential for functional improvement that could be obtained during rehabilitation. Yet, neuropathic pain is refractory to many treatments. Current interventions, such as medications and physical therapy, result in less than 50% reduction in pain for only about one third of the people trying them, calling for new treatment options. Qigong, a mind and body approach that incorporates gentle body movements, paired with a focus on breathing and body awareness to promote health and wellness, could reduce SCI-related neuropathic pain. If the hypothesis is supported, the resulting work could be transformative in demonstrating a potentially effective therapy for civilians, military Service members, and Veterans with SCI and neuropathic pain. The following provides the scientific basis for this hypothesis and establishes the rationale for this approach. This study also includes an optional, remote, quasi-experimental substudy, in which all participants will receive Qigong for 12 weeks, followed by 6 weeks followup. Read Less

The investigator aims to assess the extent to which a brief exercise intervention improves systemic growth factor concentrations, reverses loss of systemic vascular networks and hypertension, and by extension, improves neurocognition. To test the investigator's hypothesis that increased cardiovascular fitness will correlate with improved vascular density, the investigator proposes the innovative use of retinal density scans.

To investigate the effect of trazodone on sleep, hippocampal-dependent memory and hippocampal excitability. The investigators hypothesize that trazodone will improve total sleep time and proportion of time in Slow Wave Sleep (SWS). Read Less

The purpose of this study is to investigate the safe wearability and basic functions of the multi-modality sensors fabricated in the PI lab. Read Less

The purpose of this study is to longitudinally characterize and evaluate changes in synaptic density in the brain using novel positron-emission tomography (PET) scans; magnetic resonance imaging (MRI), and clinical laboratory markers associated with HIV-related injury in the central nervous system. This study will test hypotheses relating to the presence and mechanisms of aberrant brain structure at the synaptic level in living humans with virologically controlled HIV on antiretroviral therapy. To evaluate associations between PET imaging radiotracers \[11C\]UCB-J, a ligand for presynaptic vesicle protein 2A (SV2A), a vesicle membrane protein expressed in synapses, and PET \[11C\]PBR28 a measure of microglia function in the brain, the Yale PET center has developed an advanced approach of combining multiple distinct ligands in coordinated same-day PET imaging. Additionally, the study will evaluate the associations of this novel synaptic density marker with well-established clinical measures of neurocognitive performance and laboratory measures of blood and cerebrospinal fluid (CSF).

Approximately 45% of older adults in the U.S. have 2 or more chronic health conditions (e.g., arthritis, hypertension, diabetes) in addition to functional limitations that prevent performance of health self-management activities. Self-management continues to be the gold standard for managing MCC, but functional limitations create difficulty with these activities (e.g., physical activity, symptom monitoring). Restricted self-management accelerates the downward spiral of disability and accumulating chronic conditions which, in turn, increases rates of institutionalization and death by 5-fold. Currently, there are no tested interventions designed to improve independence in health self-management activities in older adults with MCC and functional limitations. Research suggests that older adults are more likely to change behavior with interventions that assist with planning health-promoting daily activities, especially when contending with complex medical regimens and functional limitations. Combined with occupational therapy (OT), behavioral activation (BA) shows promise to improve health self-management in populations with chronic conditions and/or functional limitations. This innovative combination uses the goal setting, scheduling/monitoring activities, and problem-solving components of the BA approach as well as the environmental modification, activity adaptation, and focus on daily routines from OT practice. The investigators will test the effect of this combined approach in a Stage I, randomized controlled pilot feasibility study compared to enhanced usual care. The investigators will recruit 40 older adults with MCC and functional limitation and randomize 20 to the PI- delivered BA-OT protocol. This research will inform modification and larger-scale testing of this novel intervention and provide data for a federally funded career development award. Read Less
