This study will investigate the how the cerebellum is involved in speech motor learning over time and short-term corrections in patients with cerebellar ataxia and healthy controls. This will be accomplished through three approaches: behavioral studies, magnetic resonance imaging (MRI), and transcranial magnetic stimulation (TMS). During behavioral studies, participants will be asked to speak into a microphone while their voice is played back over earphones, and to do other speaking tasks. MRI will be acquired to perform a detailed analysis on brain function and anatomy related to speech and the cerebellum. In healthy controls, TMS will also be performed to temporarily disrupt the cerebellum before, during, or after the participant performs speaking tasks. Patients with cerebellar ataxia and healthy volunteers will be asked to complete behavioral studies and/or MRI; healthy volunteers may be asked to additionally participate in TMS. Read Less

The growing population of adolescents with insulin resistance (IR) is predicted to create a large public health burden in the next few decades. This study examines the function of brain blood vessels and cognitive function, to test if increasing severity of IR in adolescents is related to reduced cognitive function and reduced brain blood vessel function. Findings from this study may help create treatments to delay or prevent some of the negative effects of IR on cognitive and vascular health. Read Less

This is a prospective, randomized trial looking at the ideal method of labor induction for women with prelabor rupture of membranes and an unfavorable cervical Bishop score. The study will compare oral misoprostol and intravenous oxytocin. Read Less

The purpose of this study is to investigate post-operative and post-radiation upper esophageal sphincter opening measures in oral cancer patients, compare measures to age- and gender-matched healthy adults, and determine relationships with patient swallowing outcomes and quality of life. Read Less

The purpose of this study is to characterize the functional status and quality of life of patients undergoing Targeted Muscle Reinnervation (TMR) at time of major limb amputation (primary) or subsequent to major limb amputation (secondary). Participants can expect to be on study for about a year and will complete a short electronic survey and option phone interview. Read Less

This is a multicenter, cross-sectional, cohort study which will collect contemporary sweat chloride (SC) values from approximately 5000 Cystic Fibrosis (CF) patients prescribed and currently receiving commercially approved Cystic Fibrosis transmembrane conductance regulator (CFTR) modulator therapies.

This study is being done in order to create a registry (list) of people interested in Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) research. It may be that you have a family member or other loved one with CADASIL, or that you may have CADASIL or are at risk. Participation means that your name will be added to a list of people who will be invited to participate in future research studies on CADASIL. Participants must be 18 years or older, and will remain on the registry until they request to be removed. Read Less

This phase III trial studies how well the addition of radiotherapy to the usual treatment (chemotherapy) works compared to the usual treatment alone in treating patients with esophageal and gastric cancer that has spread to a limited number of other places in the body (oligometastatic disease). Radiotherapy uses high energy x-rays, gamma rays, or protons to kill tumor cells and shrink tumors. Drugs used in usual chemotherapy, such as leucovorin, 5-fluorouracil, oxaliplatin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding radiotherapy to the usual chemotherapy may work better compared to the usual chemotherapy alone in treating patients with esophageal and gastric cancer. Read Less

Metabolic reprogramming has been identified as a hallmark of cancer. Almost a century after Otto Warburg initially discovered increased glycolytic activity in tumor tissue ("Warburg effect"), therapeutic targeting of cancer metabolism has become a field of intense research effort in cancer biology. A growing appreciation of metabolic heterogeneity and complexity is currently reshaping investigators "simplistic" understanding of metabolic reprogramming in cancer. Discovering metabolic vulnerabilities as new treatment targets for cancer requires systematic dissection of metabolic dependencies, fuel preferences, and underlying mechanisms in the specific physiological context. However, today's data on cancer cell metabolic signatures and heterogeneity in their physiological habitat of the human organism is sparse to non-existent representing a critical knowledge gap in designing effective metabolic therapies. Here, the investigators propose a "top-down" approach studying cancer cell metabolism in patients followed by mechanistic in-depth studies in cell culture and animal models to define metabolic vulnerabilities. Investigators will develop a metabolic tracing method to quantitatively characterize metabolic signatures and fuel preferences of leukemic lymphocytes in patients with chronic lymphocytic leukemia (CLL). Isotopic metabolic tracers are nutrients that are chemically identical to the native nutrient. Incorporated stable, non-radioactive isotopes allow investigators to follow their metabolic fate by monitoring conversion of tracer nutrients into downstream metabolites using cutting-edge metabolomics analysis. Using this method, investigators propose to test the hypothesis that leukemic lymphocytes show tissue-specific metabolic preferences that differ from non-leukemic lymphocytes and that ex vivo in-plasma labeling represents a useful model for assaying metabolic activity in leukemic cells in a patient-specific manner.

This study will evaluate the effect of the microorganisms in the gut on how well the flu or COVID-19 vaccine works in people who have a weakened immune system due to inflammatory bowel disease. Participants can expect to be in the study for up to 65 days. Read Less

This phase I trial studies the safety of transplantation with a haploidentical donor peripheral blood stem cell graft depleted of TCRαβ+ cells and CD19+ cells in conjunction with the immunomodulating drug, Zoledronate, given in the post-transplant period to treat pediatric patients with relapsed or refractory hematologic malignancies or high risk solid tumors.

The overall goal of this research is to validate and develop a non-invasive imaging biomarker of prostate cancer detection, progression, and recurrence. Development of such a biomarker may be useful to differentiate indolent from aggressive prostate cancer phenotypes allowing for selection of an appropriate risk adaptive therapy. Read Less
