Mechanisms of Malnutrition in Cirrhosis With Portosystemic Shunting
Cirrhosis is characterized by loss of muscle as well as fat mass, which increases morbidity and mortality before, during, and after liver transplantation. A common mechanism for the reduced muscle and fat mass in cirrhosis is an increased expression of the TGF (transforming growth factor)beta superfamily member, myostatin, in the …
Longitudinal Assessment of Brain Structure and Function in Juvenile-onset Huntington's Disease
The goal of this observational study is to learn about brain development in Juvenile-onset Huntington's Disease (JoHD). The main questions it aims to answer are: Is brain development different in JoHD than Adult-onset Huntington's Disease (AoHD)? Can reliable biomarkers for JoHD be found in brain structure and function? Participants will …
Study of Tumor Tissue Samples From Patients Who Have Undergone Surgery for Advanced Stage III or Stage IV Ovarian Epithelial Cancer
This research study is looking at tumor tissue samples from patients who have undergone surgery for advanced stage III or stage IV ovarian epithelial cancer. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn how tumor infiltrating T cells can predict how patients …
Computed Tomography vs. Endoscopy Study
Patients undergoing elective surgery for left-sided colon resection are asked to participate in this study: Every patient undergoes two types of examinations (endoscopy, CT scan) on day 3, 4 or 5 postoperatively. These two procedures are subject to investigation in terms of their accuracy (sensitivity, specificity) in detection of anastomotic …
CNGB1 and Allied Disorders
Mutations in the rod-expressed gene, cyclic nucleotide-gated channel beta subunit (CNGB1) and associated inborn errors in metabolism are causes of retinal disease that causes progressive loss of vision. Retinitis pigmentosa (RP) is a major cause of untreatable blindness associated with CNGB1 (CNGB1-RP). RP involves the death of photoreceptor cells that …
MRD Monitoring in Lung Cancer After Resection
The conception of molecular residual disease (MRD) extending from hematologic tumor to solid tumors. Evidences supporting MRD evaluation for lung cancer by liquid biopsy has gradually accumulated, especially circulating tumor DNA (ctDNA). In this observational study, the investigators prospectively enroll stage I-IIIA non-small cell lung cancer (NSCLC) patients who underwent …
Use of Hand-held Dynamometry to Obtain Objective Measures of Lower Extremity Force Production With Chronic Stroke
This study wants to know if using handheld dynamometry (HHD) to test leg strength in persons who have had a stroke, will reduce mistakes and give therapists better information to use for therapy. This study will collect normal values of leg muscle peak force production, cumulative peak force production, and …
The PseAn Study - Study Protocol
The researchers aim to study the role of contrast ultrasound in detecting post-traumatic splenic, hepatic, and renal PAs compared with the gold standard of CT with intravenous contrast at different follow-up time points, and whether it can replace CT scan in the follow-up of solid organ injuries
Exploring Cancer Evolution, Prognostic and Predictive Biomarkers in EGFR-mutant NSCLC
To investigate genomic architecture, cancer evolution and their relationship with clinical outcomes in EGFR-mutant NSCLC.
Scoliosis Shared Decision Making
Analysis of video encounters between providers, patients, and families will be used to develop a shared decision making tool for patients deciding between surgery and observation for scoliosis treatment.
