Filter by:This clinical trial studies how well 68Ga-PSMA-11 positron emission tomography (PET)/computed tomography (CT) works in imaging patients with intermediate or high risk prostate cancer before surgery. Diagnostic procedures, such as PET/CT scans, may help find and diagnose prostate cancer and find out how far the disease has spread.
The hepatoadrenal syndrome has been well described in the literature and is known to be associated with poorer outcomes in both stable and critically ill cirrhotic patients. In chronic liver disease, adrenal (and more specifically cortisol) insufficiency is thought to be a byproduct of altered lipid metabolism that results in decreased HDL production and thus decreased delivery of cholesterol to the adrenal for subsequent corticosteroid production. Studies to date have implicated lecithin-cholesterol acetyltransferase (LCAT) as the key enzyme which is deficient in some cirrhotic patients, leading to an impaired ability to esterify cholesterol and thus a loss of normal cellular functioning and membrane stability. The investigators seek to quantify this LCAT deficiency in a cohort of cirrhotic patients and demonstrate its association with various abnormal physiologies associated with chronic liver disease, including spur cell anemia, low HDL levels, and adrenal insufficiency. Hospitalized cirrhotic patients at UVA that meet study eligibility criteria will be approached by a member of the study team to obtain consent for participation. If a patient agrees to become a study subject, they will have an approximate total of 35ml of blood drawn the following morning. Lab tests to be performed include: peripheral blood smear, lipid panel, free cortisol, cortisol binding globulin, serum cholesterol esters (surrogate for LCAT enzyme activity), and a standard-dose cortisol stimulation test. The latter involves blood drawn with the initial collection, administration of an intravenous 250mcg dose of synthetic ACTH, and then repeat small-volume blood draws at 30 minutes and 60 minutes later. Subjects will be classified as adrenally sufficient or insufficient on the basis of as standard-dose cortisol stimulation test. Variables of interest for comparison between the groups include MELD score, Child-Turcotte-Pugh (CTP) classification, high-density lipoprotein (HDL) levels, presence of spur cell anemia, serum cholesterol ester percentage (surrogate for LCAT enzymatic activity), cortisol binding globulin levels, and free cortisol levels. Student's t-test and Chi Square tests will be utilized to determine significance; a p <0.05 value will be used as our threshold for significance. If multiple factors are found to be significantly different in a univariate fashion between classification groups, a multivariate logistic regression analysis will be performed for adjusted analysis. The investigators will also seek to define any correlations between variables. Furthermore, the investigators will assess correlation between MELD score and serum cholesterol ester percentage, spur cell anemia, HDL levels, cortisol binding globulin levels, and free cortisol levels; similar correlate analysis will be done using CTP classification instead of MELD score.
The purpose of this study is to evaluate the long-term persistence of binding antibody responses against V1V2 and gp120 in subjects who were vaccinated with the envelope glycoprotein 120 (gp120)-negative factor (Nef)Tat/ Adjuvant System 01B (AS01B) (GSKSB732461) vaccine candidate. Other immune parameters like the HIV-specific cluster of differentiation (CD4+) T cell and CD8+ T cell responses will also be evaluated.
This randomized phase II trial studies how well a health and recovery program works in increasing physical activity level in stage IA-IIIA endometrial cancer survivors. Health and recovery program which includes exercise counseling, Fitbit tracker, and phone or email/text communication may increase the level of physical activity in endometrial cancer survivors and promote and maintain behavior change at a lower cost.
A prospective study of bleeding peptic ulcers and/or erosions in the upper gastrointestinal tract - risk-medication, presence of Helicobacter pylori, treatment and outcome.
This is a single arm, open-label, phase II trial of nivolumab, ipilimumab and short-course radiation therapy in adult patients with newly diagnosed, MGMT unmethylated GBM with the primary objective of determining the overall survival at 1 year.
The aims of the study are to evaluate the effect of low-phosphate diet on FGF23 level and to determine the optimal amount of dietary phosphate restriction in hemodialysis patients. In particular, the investigators will assess the comparing effect of pre-specified low-phosphate diets, very low-phosphate diet, phosphate-to-protein ratio (PPR) value of 8 mg/g, versus low-phosphate diet, PPR value of 10 mg/g, on the change of FGF23 and phosphate level.
The purpose of this study is to quantitate electrical dyssynchrony in heart failure (HF) patients with a narrow QRS complexes (≤ 130 ms) using the ECG Belt. This is a pilot study that is designed to provide data that can be used in designing and implementing a prospective study of cardiac resynchronization therapy (CRT) in narrow QRS patients selected and optimized using the ECG Belt.
This phase II trial studies how well Nivolumab, Cisplatin, and Pemetrexed Disodium or Gemcitabine Hydrochloride in treating patients with stage I-IIIA non-small cell lung cancer that can be removed by surgery. Monoclonal antibodies, such as Nivolumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as Cisplatin and Pemetrexed Disodium or Gemcitabine Hydrochloride, 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. Giving Nivolumab, Cisplatin, and Pemetrexed Disodium or Gemcitabine Hydrochloride may work better in treating patients with non-small cell lung cancer.
Noninvasive ventilation defines methods of providing ventilation support with constant or variable pressure using nasal or nasopharyngeal interfaces without endotracheal intubation or tracheostomy. Today, short binasal prongs and different types of nasal masks are the most commonly used nasal interfaces in the NICU with the aim of providing NIV. RAM cannula (Neotech ™, Valencia, CA), a new nasal interface, is increasingly used in NID applications in newborn infants. The RAM cannula is available in the inspiration and expiration arms of the stroke while reducing the dead space in the respiratory tract due to the low nasal prong diameter. There are not enough studies comparing the effectiveness of the RAM cannula with other short binasal prongs or nasal masks. Investigators compared the effectiveness and nasal injury rates of RAM cannula and short binasal prong as NIV interfaces in preterm infants.
