Molecular Characterization of Patients Affected by Williams Syndrome and Autism.

Williams Beuren syndrome (WBS) is a multiple malformations/intellectual disability (ID) syndrome caused by 7q11.23 microdeletion and clinically characterized by a typical neurocognitive profile including excessive talkativeness and social disinhibition, often defined as "overfriendliness" and "hypersociability". WBS is generally considered as the polar opposite phenotype to...

An Immunogenic Personal Neoantigen Vaccine for Cancer Treatment

Despite years of preclinical efforts and hundreds of clinical studies, therapeutic cancer vaccines with the routine ability to limit or eliminate tumor growth in humans have been elusive. With advances in genome sequencing, it is now possible to identify a new class of tumor-specific antigens derived from mutated proteins that are present only in the tumor. These "neoantige...

Effects of Phenoximethylpenicillin, Amoxicillin and Amoxicillin-clavulanic Acid on the Gut Microbiota

The overall aim of the project is to fill an important knowledge gap on the ecological effects of selected antibiotics. The results will be used to guide treatment decisions for common infections to as much as possible reduce the negative impact on the intestinal microbiota and consequently the risks of side effect and resistance development during therapy. Specific ...

Immune Response followingTdap Vaccine in Pregnancy

Pregnancy involves changes in immune response. The investigators aim to evaluate the immune response to Tdap in pregnancy in comparison to non pregnant women usig proteomics and gene sequencing.

Targeted T-cell Therapy in Solid Tumors

This is a single-center, open, single-arm controlled prospective clinical trial of patients with solid tumors treated with targeted activation of T cells through intravenous infusion.The purpose of this study was to evaluate the clinical efficacy and safety of targeted activated T cells in the treatment of solid tumors.

Effects of Continuous Treatment With Rifaximin and Probiotics on the Gut Microbiota of Patients With IBS-D

We will use the latest Rome IV criteria to recruit IBS-D patients and evaluate the effects of repeated treatment with rifaximin and sequential treatment with rifaximin and probiotics on different symptoms and quality of life. High-throughput sequencing combined with real-time quantitative PCR will be used to comprehensively analyze the effects of different drugs on intestin...

Safety and Efficacy of Ponatinib Followed by Imatinib in Patients With Chronic Myelogenous Leukemia in Chronic Phase

The investigators hypothesize that, in newly diagnosed de novo chronic phase CML patients, an induction treatment with ponatinib for 6 months should increase the rate of patients reaching a stable MR4.5 allowing cessation of imatinib treatment. The investigators proposal is to conduct a multicenter, Phase II trial to evaluate the safety, clinical and biological activity of...

Screening Gene Mutations in Myeloid Cancers by Next Generation Sequencing to Improve Treatment Results

Genetic mutations have closely linked to the pathogenesis and prognostication of myeloid cancers. In addition, a number of molecularly targeted agents have been developed in recent years. With the advent of next generation sequencing (NGS), we now are able to detect a wide range of mutations more rapidly, accurately, and economically. In this study, the investigators will u...

The Genetic, Protein, and Lipid Basis of Variation in Cholesterol Efflux

The rationale of this research is that deep phenotyping of individuals at the extremes of cholesterol efflux will identify key determinants of efflux that are potential novel therapeutic targets to prevent or reverse Atherosclerotic Cardiovascular Disease (ASCVD). The investigators propose to carry out the objective by studying participants at extreme low and high cholester...

A Prospective Cohort of Obinutuzumab and Chlorambucil (GC) Chemotherapy for the Treatment of Elderly Patients With Chronic Lymphocytic Leukemia Including Next- Generation Sequencing (NGS)-Based Assessment

This study is prospective, open-label, single arm observational study to assess efficacy of obinutuzumab plus chlorambucil (GC) chemotherapy in treatment naïve CLL, and prognostic impact of genetic alterations for CLL using NGS.

Interest of Rapid Typing in Adenovirus Infections.

Proposal of a "rapid typing" technique by a new real-time PCR method, simpler, faster and cheaper than nucleotide sequencing (reference method) for rapid typing in Adenovirus infections.

Gut Microbiome and ICU Delirium Post Cardiac Surgeries

ICU delirium are assessed by clinical nurses twice every day. Delirious patients are matched with patients according to their disease, gender and age range(±3 years). Stool samples for gene sequencing are collected. Gut barrier function are studied with several serum biomarkers (endotoxin, etc.). Ecological analyses, regression models and mediation equation will be perform...

A Clinical Trial of Silver Diamine Fluoride to Arrest Early Childhood Caries in Young Children

Silver diamine fluoride (SDF) is an antibiotic liquid that has the potential to arrest Early Childhood Caries in young children and delay treatment until children can be seen in outpatient settings. While SDF received approval for clinical use in Canada in 2017 (i.e. Advantage Arrest TM/38% SDF), there has been little guidance on the frequency and duration of applications. ...

MOLecular Characterization and Treatment of THYroid Carcinoma on Struma Ovarii

Thyroid carcinoma on struma ovarii (TCSO) is a rare ovarian tumor, derivate from monodermic teratomas. It represents about 0.01% of overall ovarian tumours, and 5 to 10% of struma ovarii. The diagnosis is histologic and retrospective after pelvic surgery. Because of its rarity, the treatment of TCSO is not consensual and should be validated in multidisciplinary team involve...

The Occurrence of Single Nucleotide Polymorphism Among Women Who Experienced Obstetric Anal Sphincter Injury

Single-nucleotide polymorphisms (SNP's) in connective tissue components are associated with increased risk of pelvic organ prolapse (POP). The investigators expect to find a difference in SNP's frequency between women who had Obstetric anal sphincter injuries (OASIS) and in the healthy population. The fact that pelvic organ prolapse (POP) and OASIS occurs in the same anatom...

Promoting Clinical Guidelines for Opioid Prescribing

This study aims to understand the optimal sequencing and combination of implementation strategies that specific types of clinics and prescribers need to adopt clinical guidelines for opioid prescribing. The pragmatic goal is to give health systems a tool they can use to predict which clinics and prescribers will benefit most from which sequence and combination of implementa...

Febrile Disease Landscape in Cambodia Via Metagenomic Pathogen Sequencing

Background: Vector-borne diseases are caused by the bite of an infected mosquito, fly, flea, tick, or other blood-feeder. These diseases cause almost 1 million deaths per year. And they are on the rise, particularly in Southeast Asia in particular. Researchers think that these diseases make up about 10 percent of fevers in Cambodia. But many of these illnesses are never ...

Randomized Controlled Trial of IVIG/Rituximab Versus Rituximab in Kidney Transplant With de Novo Donor-specific Antibodies

Although recent advances in immunosuppressive regimens after kidney transplantation (KT) have reduced the incidence and consequences of T-cell-mediated rejection (TCMR) and have improved short-term outcomes, long-term allograft loss attributable to antibody-mediated rejection (AMR) is still responsible for substantial medical and socioeconomic burdens in kidney transplant r...
