The purpose of this study is to quantify and analyze the line accesses for each of the 3 participating ICUs. The hypothesis is that the CICU will have a significantly higher number of line accesses than the other units. Analyzing the data will assist the researchers in identifying best practices and ultimately, reduce the BSI rate in the CICU.
The overall goal of this Community Central Line Infection Prevention (CCLIP) trial, supported by grant R01 HS022870 from the Agency for Healthcare Research and Quality, is to determine whether use of a promising new intervention, namely 70% isopropyl alcohol embedded protective caps on central lines, in the home setting is associated with a reduction in ambulatory central line-associated bloodstream infections (CLABSI) in a high-risk population of pediatric hematology/oncology ...
Intravenous catheters are often placed in large (central) veins in critically ill patients to provide special medications or frequent blood sampling. The body reacts to the presence of foreign material by forming a biofilm on the surface within the catheter. Either due to the patients condition or to emergency access to these intravenous lines can become infected with bacteria and reside within the biofilm. When bacteria is grown from these lines it is referred to as: a central...
Central venous lines insertion are common procedures these days. CVL placed under USG guidance have high success rates and low complications even in developing country settings. However, the investigators still have to rely on chest x-ray (CXR) to confirm the correct placement of central venous lines as a gold standard method. This might be time consuming and may cause delay in initiation of treatment. In some cases, as in operating room, the treatment is started even before co...
This proposed collection of primary tumor cells lines will benefit esophageal cancer research within the University Health Network. This collection of gastro-esophageal tumor samples will be used to grow primary tumor cell lines, which will provide researchers with ready samples of various gastro-esophageal cancers. This will help to address the issue of access to these cell lines due to the limited number of patients with gastro-esophageal tumors, and high rates of contaminati...
RSH/Smith-Lemli-Opitz syndrome (SLOS) is one that causes mental retardation. It is common in the Caucasian population but rare in African American and African black populations. It has been shown that SLOS is caused by a specific defect in DHCR7, an enzyme used in cholesterol metabolism. Studies have already been done to determine the frequency of the SLOS-causing mutations in various geographic Caucasian populations. This study will investigate the frequency of the DHCR7 mutat...
RATIONALE: Collecting and storing samples of blood from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This research study is collecting and storing blood samples from patients with cancer.
Recent advances have shown that cells from human blood, skin and urine samples can be reprogrammed to become stem cells. These are called induced Pluripotent Stem Cells (iPSCs) and share many characteristics with embryonic stem cells, including an unlimited capacity for proliferation and the potential to become any cell in the body. Beneficially, the use of iPSCs avoids the ethical difficulties which surround embryonic stem cells and allows generation of iPSC lines which are di...
To evaluate the potential of a new imaging device, termed Optical Frequency Domain Imaging (OFDI), in the early diagnosing of pulmonary malignancies in the central airways.
RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at blood and cheek cell samples from patients with glioma.
RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at tissue and blood samples from patients with low-grade glioma.
The purpose of this research study is to see if factor levels and inhibitor levels in Hemophilia A and B subjects are accurate when they are drawn from a central venous line (CVL) instead of from a peripheral stick.
A prospective, non-randomized study to evaluate the performance of the MyoScience Tissue Remodeling Device for the treatment of glabellar lines (frown lines), lateral orbital lines (crow's feet), and frontalis lines (horizontal forehead lines).
Background: - Information and samples collected from participants in medical research studies can be useful even after the original study is complete. Researchers can use the information and samples to learn more about multiple sclerosis or other immune system disorders. They can also be used for research into other disorders. Researchers would like to get permission to use samples collected from older studies to launch new lines of research. Objectives: - To loo...
Hereditary Haemorrhagic Telangiectasia (HHT, also known as Osler-Weber-Rendu Syndrome) is an disease that leads to the development of dilated and fragile blood vessels. We propose to take blood samples from patients with HHT, and culture white blood cells that express the proteins mutated in HHT, namely endoglin and ALK-1. We will study the properties of these cells which will involve their growth in media prompting different types of differentiation, or infection of cell lines...
There are few studies in the literature regarding increased frequency of neuropathic pain and sleep disturbance and decreased quality of life in Behçet's disease. Frequency of central sensitization was not investigated in patients with Behçet's disease before. In this study, it is aimed to investigate the frequency of central sensitization, neuropathic pain, sleep disorder and quality of life and their relation to each other in Behcet's disease.
Recent studies suggest that cells in the bone marrow-endothelial precursor cells (EPCs)-can provide a blood supply to cancerous tumors. The purpose of this study is to collect brain tumor and blood samples to look for these EPCs in the samples and analyze the growth signals that may help blood vessels to grow in tumors. Researchers will study the following in the samples: 1) the number of blood vessels in the tumor; 2) the levels of growth factors in the tumor and blood; 3) t...
Comparison of non-invasively obtained central blood pressure using SphygmoCor and invasively recorded central blood pressure in patients with an AAA that will be treated with EVAR.
Measurement of the amount of blood pumped by the heart (cardiac output) and blood volumes in sick patients is important for doctors to better treat these patients. Current procedures available demand difficult invasive procedures and hence these parameters are not measured with enough frequency and are also limited to certain patients. The new COstatus system is capable of using the already existing arterial and venous lines placed in critically ill patients and thus provides a...
Multicenter randomized study to compare powered intraosseous access to standard central line access for the administration of fluids and drugs for patients in the Emergency Dept.
This is a study looking at the use of sodium bicarbonate to restore the flow of blocked central line devices in patients with blood cancers. Central line devices uses thin tubes that are placed into a vein in the body to give medicines, fluids, nutrients, blood products, etc. Sometimes, the lines become blocked. The standard procedure to get the line working again is to use alteplase, a protein that dissolves blood clots. While blood clotting is one cause of a blocked l...
There is growing evidence that central blood pressure is a better predictor of hypertensive end-organ damage and cardiovascular outcome than routine brachial readings. We aimed to evaluate the accuracy of a novel device for the non-invasive determination of central blood pressure based on automated oscillometric radial pulse wave analysis.
Most children admitted to paediatric intensive care units (PICU) need to have medicines given to them into their veins using a narrow tube, so they do not need repeated injections. This tube is called a central venous catheter. Occasionally these catheters can cause infections in the blood and sometimes the tubes can get blocked by small blood clots. Some intensive care units already use antibiotic or heparin coated catheters, but there is no proof that these are better than t...
In non-small celled lung cancer (NSCLC) 10-15% of the patients harbor a mutation in the tumor's epidermal growth factor receptor (EGFR M+). This receptor is the target for treatment with erlotinib. Identification of EGFR M+ is done on a biopsy, which can be difficult to retrieve. A new blood based test identifies EGFR M+ in plasma, which makes it possible to monitor the level of EGFR M+ in the patient's blood during treatment. This enables both a closer monitoring of the treatm...
Background: - It is not fully understood why prostate cancer in some men becomes androgen-independent (no longer responds to anti-androgen medication), but genetics likely plays an important role. - Genes contain the hereditary information that is passed down from parents to children. Although everyone has the same set of genes, individuals can have different forms of the same gene. - Differences in genes may explain, at least in part...
