Filter by:This is a retrospective, proof of concept study, which aims at reconstructing the cellular heterogeneity of the tumor in multi-needle diagnostic prostate biopsy as well as any biopsy containing potentially pre-malignant tissue, to study its implications in the clinical history of the disease. For each patient, 2 or more samples will be prepared starting from the FFPE diagnostic material. The biopsy used for assigning the Gleason score will be sequenced, together with two or more of the local peri-proximal biopsies with a higher level of differentiation. Samples will undergo Whole Exome Sequencing with an average coverage of 300x at the Wellcome Sanger Institute (WSI, Hinxton, UK). Sequencing data will be analysed for single nucleotide variants, copy number variants and structural variants by using state-of-the-art data analysis pipeline at WSI. 1. Reconstruction of local PCa heterogeneity in multi-needle diagnostic biopsy with different Gleason scores (6-10) using high-coverage whole exome sequencing (WES) and DP-based clonal analysis; 2. Characterization of the relationships between pathological differentiation (Gleason score) and genomics-measured heterogeneity and malignancy features; 3. Assessment of clinical implications of clonal heterogeneity. The study will include an average of 150 prostatic diagnostic biopsies from a cohort of 20 early metastatic PC patients and 20 non-relapsing/non-metastatic patients with indolent malignant disease.
A case-control study to identify microbiome and genetic differences between healthy subjects and patients with incident Parkinson's disease.
Pursuing very early diagnosis is standard of care for several diseases including colon cancer, diabetes and liver disease where an early and aggressive diagnostic and therapeutic approach has been shown to change their natural history. Crohn's disease [CD] still lags since commonly at presentation CD has already run a long course, often responding poorly to therapy or requiring surgery. This innovative project proposes a minimally invasive strategy - capsule endoscopy-based screening of first degree relatives [FDR's] of CD patients - to develop tools to diagnose CD at or near its biologic onset.
The primary objective of the following randomized open label trial is to demonstrate how low immunological risk patients (no anti HLA immunization and first kidney transplantation) but diagnosed at high-risk of delayed graft function (assessed by DGFS score) could benefit from induction with ATG for preventing delayed graft function compared to Basiliximab.
IQP-AS-105, is a food supplement derived from garlic (Allium sativum). The objective of this study is to evaluate the possibilities of clinical use of IQP-AS-105 as a preventive medicine, based on its ability to enhance the immune system responses
Background: -Tuberculosis (TB) is an infection of the lungs caused by bacteria. In Mali, TB is diagnosed with a test that is fast and inexpensive but not always accurate. The purpose of this study is to test a new method for diagnosing TB, called the microscopic-observation drug-susceptibility (MODS) test. The MODS test takes 7 days to show results. The test also gives information on which drugs will work best in each case. Objective: -To test a new method for diagnosing tuberculosis called the microscopic observation drug susceptibility test. Eligibility: - Participants must be 12 years of age or older. - They must have a diagnosis of TB from a sputum smear, or have symptoms of TB and an x-ray indicating that TB is present. Design: - Participants will take part in the study from 6 months to 21 months and be assigned to one of three groups, depending on what type of TB they have. - At the first visit, researchers ask questions about general health and symptoms of TB. They check vital signs, draw blood, and ask for a sputum sample. The blood is used to check for HIV infection and for the number of CD4 cells, which measures the severity of the HIV infection. - The 2-, 5-, and 6-month visits are similar to the first. Those who do not have multidrug-resistant (MDR) TB will end their participation after the 6-month visit. MDR TB is tuberculosis that has not responded to isoniazid and rifampicin. Participants with MDR TB will remain in the study for 21 months. - No treatment is provided as part of this study.
Our main goal is to create a prospective cohort of 1500 patients with a first large myocardial infarction allowing us, in a second step, to identify susceptibility genes for the progression of patients towards chronic heart failure using a candidate gene/candidate pathway approach. Our main hypothesis is that there is, for a given initial biomechanical stress (duration of the ischemic episode, size of the infarcted area, etc.), a variation in the individual susceptibility to develop left ventricular remodelling and to progress towards heart failure, and that this variation is linked to genetic variants between individuals.
C. dubliniensis has been identified as pathogen in Oropharyngeal Candidiasis(OPC)particularly among HIV patients. Azole therapy is a cornerstone in OPC, but resistance within C. dubliniensis isolates to diflucan is common.This is a prospective collection of biological specimens from oropharyngeal cavity with the purpose of determining the prevalence of C. dubliniensis in HIV/AIDS patients at the Duval County Department of Health Comprehensive care Center. It is hereto proposed an estimation of azole-resistance in these isolates.
Gouty diathesis describes uric acid or calcium oxalate nephrolithiasis and low urinary pH (<5.5). A hereditary component has been outlined for several forms of nephrolithiasis (such as hypercalciuria, hyperoxaluria, cystinuria, renal tubular acidosis), leading to the hypothesis of a genetic predisposition to nephrolithiasis. At the Unit of Nephrology, Ospedali Riuniti di Bergamo, more than 100 patients affected by gouty diathesis are followed. Fifty percent of them has a familiarity for kidney stones formation. The aim of our study is to identify the genetic factors that predispose to the development of nephrolithiasis in patients with gouty diathesis.
