Management of an Imipenem-resistant Acinetobacter Baumannii Alert in a French University Hospital
Colonization with imipenem-resistant Acinetobacter baumannii (IBA) is an unfavorable event for the patient, especially in intensive care. Indeed, it exposes the patient to the risk of developing serious infections, extremely difficult to treat. ABRI is a particularly resistant bacterium in the environment. When an ABRI epidemic occurs in a department …
Early Childhood Obesity Programming by Intrauterine Growth Restriction
The molecular mechanisms underlying developmental programming of childhood obesity remain poorly understood. Here, the investigators address major questions about early childhood obesity programming by studying CD3+ T-cells from intrauterine growth restricted (IUGR) newborns who have an increased risk for obesity and other metabolic disorders in adult life.
The Role of Endothelin 1 as a Marker of Renal Impairment in Sickle Cell Disease
Sickle cell disease (SCD) refers to a group of hemoglobinopathies that include mutations in the gene encoding the beta subunit of hemoglobin. Within the umbrella of SCD, many subgroups exist, namely sickle cell anemia (SCA), hemoglobin SC disease (HbSC), and hemoglobin sickle-beta-thalassemia (beta-thalassemia positive or beta-thalassemia negative). Several other minor …
The circTeloDIAG: Liquid Biopsy for Glioma Tumor
Gliomas represent the most frequent primary brain tumor, with 2,500 to 3,000 new cases per year in France. Their diagnosis, although highly complex, is essential for determining patient management. While grade I gliomas (infrequent) are curable by surgery or present a slow progression, grades II to IV require heavy treatment …
Longitudinal Study of Xenon-129 MRI Imaging Effects of Cannabis Smoking
This is a longitudinal study of the long-term health impact of cannabis smoking on the lungs. Participants will be followed over a period of 3 years, and impacts of cannabis smoking on the lungs will be measured with magnetic resonance imaging (MRI) using hyperpolarized xenon-129 gas, pulmonary function tests, exercise …
Evaluating and Monitoring Immune and Clinical Responses in Early-Stage Triple Negative Breast Cancer Undergoing Neoadjuvant Chemo-immunotherapy With Pembrolizumab
This research study is a prospective, single arm, pilot study, designed to evaluate the correlation between the immune and clinical responses of subjects with untreated Stage II-III triple negative breast cancer (TNBC) undergoing standard of care neoadjuvant chemo- immunotherapy.
Validation of the Dutch Translation of the Tobacco, Alcohol, Prescription Medication and Other Substances (TAPS)-Tool
The aim of the study is to investigate the reliability and validity of the Dutch version of the TAPS-tool. This will be investigated in 2 groups: patients without intellectual disabilities treated in Flexible Assertive Community Treatment (FACT) teams and patients with intellectual disabilities. For the later group, an adjusted version …
