NCT ID: NCT01580683 Withdrawn - Atrial Fibrillation Clinical Trials

Vitamin C and Atrial Fibrillation After Cardiac Surgery

Start date: July 2012
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine if vitamin C decreases the chance of developing atrial fibrillation, a type of arrhythmia or irregular heartbeat, following cardiac surgery. This irregular heartbeat is a common occurrence following cardiac surgery, and occurs in about one third of patients. It poses extra risks to people who develop it. Our hypothesis is that Vitamin C will decrease the incidence of postoperative atrial fibrillation.

Harvest, Isolation and Culture of Cardiac Stem Cells From Endomyocardial Biopsies

Start date: February 2011
Phase:
Study type: Observational

The purpose of this study is to determine whether the harvest, isolation and culture of cardiac stem cells from endomyocardial biopsies is feasible.

NCT ID: NCT01574677 Withdrawn - Colorectal Cancer Clinical Trials

Assessment of Septin9 Biomarker for Detection of Colorectal Cancer in Patients With Positive Fecal Immunochemical Test

Start date: June 2012
Phase: N/A
Study type: Observational

Colorectal cancer (CRC) is the second leading cause of cancer death in the United States and affects men and women almost equally. The United States Preventative Services Task Force (USPSTF) currently recommends screening with any of three options, which include fecal testing, flexible sigmoidoscopy, or colonoscopy. Screening for CRC with fecal occult blood testing (using a guaiac-based test) done annually or biennially has been shown to decrease mortality 15-33% primarily through detection of early stage cancer. Guaiac fecal occult blood testing (gFOBT) has a known positive balance of benefit and risk in screening populations, is the least expensive, and is the preferred method of screening in 30-55% of patients. The fecal immunochemical test (FIT) offers significant improvements over the gFOBT, most notably that it is easier to use (requires fewer samples and no dietary or medication restrictions) and is more sensitive than the gFOBT with respect to detecting both CRC and precancerous adenomas. As a result of improved test performance and usability, in 2008 multiple professional societies endorsed the use of four types of FITs for colorectal cancer screening. Kaiser Permanente currently uses the OC-Micro FIT as the fecal screening test in all regions. In recent years, intensive efforts have been undertaken to identify blood-based markers that may provide a promising alternative or supplement to fecal testing for non-invasive CRC screening. One method under development is to identify aberrantly methylated genes in cancer tissue through a blood test. Prior studies have explored those specific colorectal cancer genes that show the highest differences in methylation between the cancer and background genetic expression. Of these, methylation of the Septin 9 gene through a qPCR assay is relatively well studied. The proposed study aims to evaluate whether the Septin 9 biomarker may be used to supplement the OC-Micro FIT for colorectal cancer screening in such a way as to safely reduce unneeded colonoscopies. The population of interest for this study—those with a positive screening OC-Micro fecal immunochemical test—has a CRC prevalence of approximately 5%. Knowing how well Septin 9 can identify those without cancer prior to colonoscopy is important largely because colonoscopy, even when done diagnostically (e.g., after a positive FIT result), can cause serious complications.

NCT ID: NCT01574664 Withdrawn - Clinical trials for Non-palpable Breast Lesions

Evaluation of RFID Localization System for Marking and Retrieving Breast Lesions

Start date: September 2012
Phase:
Study type: Observational

The goal of this investigation is to obtain clinical data to show the Health Beacons Radiofrequency Identification (RFID) Localization System is safe and performs as intended as a localization device for marking and retrieving a non-palpable surgical target from the breast.

NCT ID: NCT01573806 Withdrawn - Inflammation Clinical Trials

Pharmacology of Exenatide in Pediatric Sepsis

PEPS
Start date: October 2012
Phase: Phase 1/Phase 2
Study type: Interventional

Pharmacology of Exenatide in Pediatric Sepsis, PEPS is a phase 1-2 research study that will examine drug safety, drug metabolism, drug action and preliminary drug clinical effects of four does of exenatide injected every 12 hours to children with shock from infection (septic shock). The investigators hypothesize that exenatide can be safely dosed to children with sepsis to achieve blood levels of drug similar to that achieved in teenagers with type 2 diabetes. The investigators further hypothesize that injection of exenatide to children with septic shock will normalize blood glucose levels and decrease levels of inflammation proteins in the blood during the early course of sepsis.

NCT ID: NCT01573390 Withdrawn - Clinical trials for Quantitative Validation of Imaging System

Non Invasive and Non-Contact Imaging Of Tissue Oxygenation and Vascular Reactivity

Start date: n/a
Phase:
Study type: Observational

1. Quantitative validation of non-contact oxygenation imaging by the CWC imaging system 2. Quantitative validation of non-contact vascular function imaging by the CWC imaging system 3. Evaluation of the clinical usability of the CWC imaging system for further technology development and engineering improvement

NCT ID: NCT01570543 Withdrawn - Implants Clinical Trials

MRI Scanning of People With MR Safe Orthopedic Implants That Are Made of Metal

MRI
Start date: March 2012
Phase: N/A
Study type: Observational

The purpose of the study is to improve image quality, increase speed of scanning and to see how well certain products test by scanning people who have an orthopedic hip or knee metallic implant.

NCT ID: NCT01569854 Withdrawn - Clinical trials for Hypercholesterolemia

Genetic Influence on Statin Pharmacodynamics

Start date: March 2012
Phase: N/A
Study type: Observational

The study intends to investigate whether genetics influence how individuals respond to statins (clinical outcomes and changes in carotid intimal media thickness)

NCT ID: NCT01569633 Withdrawn - Infant,Premature Clinical Trials

Use of Prokinetics in Early Enteral Feeding in Preterm Infants

Start date: October 2011
Phase: N/A
Study type: Interventional

Objective of this study are: 1) To determine if medication help extreme preterm infants to tolerate feeding better by reaching full feeding earlier.2) Out of two medication; which one is better for efficacy 1) Erythromycin 2) Metoclopramide. Infants who meet inclusion criteria would be entered to study after parental consent. Infant would be blinded to care givers. Infants will be randomized to receive one of three medication for 7-14 days. If infants fail on one medication they will be allowed to crossover to other medication. Infant would be allowed to treat like other infants. Blindness can be broken if deem necessary by attending neonatologist.
