The main objective is to identify new virulence factors produced by Staphylococcus lugdunensis that can be associated with clinical sign of severe infections and identified symptoms. The methodological approach is based on the comparison between the production of toxins by a give…

In men presenting sperm alterations, the selection of genetically undamaged spermatozoa need to be improved in order to increase the success of assisted reproduction treatments. The aim of this study is to determine whether the presence of sperm head vacuoles is associated with …

The primary goal of the study is to evaluate the use of a new smart phone application in preventing relapse to smoking among people with PTSD. The technology intervention will combine a mobile system to reward non-smoking, smoking cessation counseling, smoking cessation medicatio…

Research of predictive clinical and biological factors in breast cancer : genomic, proteomic, mutation

The study's overall objectives are to evaluate the safety of anakinra in combination with standard chemotherapy regimens in patients with pancreatic ductal adenocarinoma, as well as to collect preliminary immune modulation and clinical activity information, overall survival, and …

The investigators conducted a large, multicenter retrospective study of patients with breast cancer leptomeningeal metastasis (BCLM), constituting one of the largest and most comprehensively curated cohorts to date. Data from 403 patients diagnosed between November 2013 and Novem…

The respiratory epithelium plays a leading role in the development of allergic respiratory disease with barrier function alteration, its repair mechanisms, of anti-viral fight and the ability to induce by itself Th2 responses. The majority of allergic asthmatic patients have reac…

The investigators set out to determine whether malnutrition delayed healing of foot lesions in diabetic patients.

PET has an established role in the initial staging of patients with newly diagnosed lung and gastrointestinal tumors.PET avidity is described with both maximum and mean standardized uptake values.Malignant cells have increased activity on PET, defined as the standardized uptake v…

This phase I trial studies the side effects and best dose of stereotactic body radiation therapy in treating patients with prostate cancer after undergoing surgery. Stereotactic body radiation therapy may be able to send x-rays directly to the tumor and cause less damage to norma…

This research trial establishes a breast tumor tissue repository from core biopsies. Collecting breast tissue from core biopsies may allow doctors to learn more about the biology of breast cancer and to analyze proteins, genes, and other components of tumor cells. It may also all…

Patients who have sickle cell VOC are usually treated with opioids, such as morphine. However, this current way of treating them has not improved the health, medical outcomes, or rates of hospitalizations. In addition, since VOC can happen very frequently over a long period of ti…

The purpose of this prospective study is: * to identify by cluster analysis the main phenotypes of severe asthma and factors involved in the severity, * to determine the clinical and functional outcomes, * to identify the factors associated with severe asthma from childhood to a…

Computer simulations are being developed to predict air flow abnormalities in the airways of patients with lung disease. The purpose of this study is to obtain actual gas flow measurements in the lungs of healthy patients and patients with lung disease and use these measurements …

Background: \- An ongoing study is looking at American Indians who have kidney problems caused by type 2 diabetes. Kidney disease due to type 2 diabetes is a major problem in American Indians. We previously found that early treatment of kidney disease with losartan was probably …

To gather preliminary safety and outcome data for the multimodality treatment of lung adenocarcinoma in the setting of multifocal BAC.

The purpose of this study is to better understand why pancreatic cancer develops in some people who are known carriers of the gene mutation (an abnormality) called BRCA, or its close relative PALB2. The investigators hope to do this by establishing a BRCA/PALB2 mutation carriers …

Since 2009, a programmatic community-based strategy (COPE) has been implemented to address health disparities among Navajo individuals living with multiple chronic conditions. COPE (Community Outreach and Patient Empowerment) targets individual, family, and health system-level fa…

Cardiovascular complications of NSAIDs, selective for inhibition of COX-2, stimulated interest in microsomal prostaglandin E synthase-1 (mPGES-1) as an alternative drug target. Global deletion of mPGES-1 in mice suppresses PGE2 and augments PGI2 by PGH2 substrate rediversion. Unl…

The TVT Registry™ is a benchmarking tool developed to track patient safety and real-world outcomes related to the transcatheter mitral valve repair (TMVR) procedure. Created by The Society of Thoracic Surgeons (STS) and the American College of Cardiology (ACC), the TVT Registry i…
