Stereotactic Radiosurgery for Essential Tremor and Parkinsonian Tremor Tremor Essential Tremor Parkinson Disease Radiosurgery Quality of Life The purpose of this study is to determine the changes in quality of life and degree of tremor for patients with essential tremor or Parkinsonian tremor who are treated by stereotactic radiosurgery (SRS). This is a questionnaire-based study. Please see Detailed Description below for more information. expand The purpose of this study is to determine the changes in quality of life and degree of tremor for patients with essential tremor or Parkinsonian tremor who are treated by stereotactic radiosurgery (SRS).

2-HOBA Phase 2 Clinical Trial in Rheumatoid Arthritis Rheumatoid Arthritis This is a phase 2 study to determine 2-HOBA's tolerability, safety, and effect on isoLG-adducts in patients with rheumatoid arthritis (RA) patients. Up to 32 subjects will be randomized to 750mg 2-HOBA or matching placebo three times a day for 4 weeks. As primary outcome measures investigators will... expand This is a phase 2 study to determine 2-HOBA's tolerability, safety, and effect on isoLG-adducts in patients with rheumatoid arthritis (RA) patients. Up to 32 subjects will be randomized to 750mg 2-HOBA or matching placebo three times a day for 4 weeks. As primary outcome measures investigators will compare tolerability and adverse events and changes in isoLG adducts in active and placebo arms. Among prespecified exploratory outcomes investigators will compare changes in markers of inflammation, DAS28 score, and 24-hour blood pressure in active and placebo arms. This pilot study will inform the feasibility and design of future studies to examine the efficacy of 2-HOBA in RA patients. Type: Interventional Start Date: Aug 2022 open study
Imaging Sodium and Lymphatics in Lymphedema Lymphedema of Leg Lymphedema, Secondary Lymphedema Related Fibrosis Recent evidence supports lymphatic regulation of tissue sodium handling, however fundamental gaps persist in knowledge regarding the role of lymphatics in human diseases of sodium dysregulation.

The goal of this work is to apply novel, noninvasive imaging tools to measure relationships between lymphatic function and tissue sodium in patients with well-characterized lymphedema. Findings are intended to inform mechanisms of lymphatic clearance of tissue sodium, and provide novel imaging biomarkers of lymphedema progression and treatment response.

Memantine for the Treatment of Cognitive Impairment in Systemic Lupus Erythematosus Lupus Erythematosus, Systemic A phenome-wide association study (PheWAS) identified an association between a variant in the human gene for the N2A subunit of the N-methyl-D-aspartate (NMDA) receptor, GRIN2A, and Systemic Lupus Erythematosus (SLE). A single nucleotide polymorphism (SNP) in this gene encodes for increased NMDA receptor... expand A phenome-wide association study (PheWAS) identified an association between a variant in the human gene for the N2A subunit of the N-methyl-D-aspartate (NMDA) receptor, GRIN2A, and Systemic Lupus Erythematosus (SLE). A single nucleotide polymorphism (SNP) in this gene encodes for increased NMDA receptor activity. Based on the potential function of the associated SNP and published literature, alterations in SNP function signaling may underlie a cluster of symptoms. The objective of this study is to evaluate the safety, tolerability and efficacy of memantine, an NMDA receptor antagonist, in a precise patient subset with SLE. Participants will complete a full 14-week clinical trial, receiving either memantine or a placebo. Participants' blood will be drawn to test for various antibodies as well as organ function. Patients' urine will also be collected to assess organ function and pregnancy for females at a number of specific time points. The overall goal is to develop a safe and inexpensive therapeutic approach to reduce debilitating cognitive symptoms in a precisely selected SLE sub-population. Type: Interventional Start Date: Aug 2018 open study
Effect of PDE5 Inhibition on Adipose Metabolism in Humans Obesity This is a randomized, double-blinded, placebo-controlled study of the effects of PDE5 inhibition with tadalafil on adipose tissue in obese individuals. Adipose metabolism will be measured using magnetic resonance imaging (MRI) scans and by aspirating a small amount of adipose to measure gene expression. expand This is a randomized, double-blinded, placebo-controlled study of the effects of PDE5 inhibition with tadalafil on adipose tissue in obese individuals.

EMT en Español for Spanish-speaking Toddlers With Language Delays Language Development Disorders The goal of the study is to conduct an initial efficacy study of a promising therapist and caregiver-implemented communication intervention to improve language and school readiness skills in low-income Spanish-speaking children with receptive and expressive language delays (ages 30 to 36 months).... expand The goal of the study is to conduct an initial efficacy study of a promising therapist and caregiver-implemented communication intervention to improve language and school readiness skills in low-income Spanish-speaking children with receptive and expressive language delays (ages 30 to 36 months). The proposed randomized trial compares the effects of a caregiver plus therapist implemented EMT en Español intervention to a community based "business as usual" control group at four time points (pre- intervention, post-intervention, 6 month follow-up, 12 month follow-up) in a sample of 84 low-income, Spanish-speaking families and their toddlers with receptive and expressive language delays.
