There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Obtaining intravenous access is difficult in the pediatric population. Ultrasound-guidance allows real-time visualization of target veins which are invisible and impalpable. We hypothesize that the use of ultrasound by a trained nurse team would improve the success rate of peripheral intravenous catheter insertion in pediatric patients with difficult intravenous access, compared to palpation of the vein alone. For this study, when peripheral intravenous catheterization will be indicated in one of the participating pediatric services for an eligible patient, state-certified nurse investigators, trained in ultrasound guidance, will be contacted. After verification of eligibility criteria and all informed consents obtained, one of the investigators will randomize the patient in one of the 2 treatment groups under study: peripheral intravenous catheterization by visualization and palpation of the vein alone (standard of care) or by ultrasound guidance performed by a trained nurse. Several outcomes will be measured and compared between the 2 groups (e.g. successful insertion of intravenous catheter, pain, adverse events).
The transition between adolescence and adulthood (generally defined as ages 18 to 25) is a key developmental window for narrative identity and psychotic disorders. Narrative identity is positively associated with mental health. This study will focus on the acquisition of narrative identity in First Episode Psychosis (FEP) and its impact on multidimensional subjective well-being. The study authors hypothesize that levels of the various components of narrative identity would be lower in the FEP group than in the "chronic" and control groups, and in the "chronic" group versus control group. Given the paucity contradictory nature of the published literature, no hypotheses have been formulated regarding these correlations and predictions. Instead, this study will remain an exploratory analysis in the different samples.
Preeclampsia is a hypertensive disorder of pregnancy associated with important maternal and perinatal mortality. It complicates 2 to 5% of pregnancies and causes more than 70 000 maternal deaths each year worldwide. Although symptomatic management has improved there is currently no curative treatment, and only childbirth and delivery of the placenta, usually prematurely, alleviate the mother's symptoms. The management of extremely preterm infants is a major societal challenge in medical, ethical and economic terms. Placental insufficiency plays a central role in the pathophysiology of preeclampsia. Abnormal placentation during the first trimester leads to placental hypoperfusion, which induces trophoblast dysfunction and the release in maternal circulation of trophoblastic factors leading to the maternal symptoms. Among molecules that participate to the pathophysiology of preeclampsia, one of the most important players is soluble fms-like tyrosine kinase 1 (sFlt-1), which is a soluble form of the vascular endothelial growth factor (VEGF) and placenta growth factor (PlGF) receptor. sFlt-1 binds to free VEGF and PlGF in the maternal circulation, thus reducing their bioavailability for their membrane receptors. Targeting the sFlt-1 pathway is one of the most promising strategies for the development of new treatments for preeclampsia. As sFlt-1 results from alternative splicing, its peptide sequence is identical to that of the extracellular part of the membrane receptor. The development of drugs that act specifically on the soluble form and not on the membrane form is therefore particularly complex. The general objective of this research is to restore the angiogenic balance that maintains the physiological concentrations of free angiogenic factors in order to significantly prolong the pregnancy and diminish the consequences of the great prematurity. The precise objectives of the APHERESE 2 project are: 1. To transpose the proof of concept of the APHERESE1 project to the scale of a real apheresis column 2. To develop an innovative assay technology to determine the global circulating angiogenic balance for each patient
The purpose of this study is to determine if IN fentanyl (1.5 µg/kg) or IN ketamine (1 mg/kg) is more effective at 30 minutes than oral morphine (0.5 mg/kg) in reduction of moderate and severe pain associated with limb injuries in patients 2-17 years of age presenting to the ED.
To demonstrate the prognostic value of using post-therapy 177Lu-PSMA SPECT/CT versus 68Ga-PSMA-11 PET/CT in mCPRC patients progressing despite chemotherapy and treated with 177Lu-PSMA.
Lack of knowledge of digestive absorption of drugs used in metabolic syndrome (MS) before and after gastric by-pass (GBP) in obese patients. The main objective is to study the changes in apparent clearance of candesartan, amlodipine, metformin and rosuvastatin, used in the treatment of metabolic syndrome in obese patients, between the preoperative period and 1 and 6 months after the performance of a GBP.
First described in cardiac surgery, the aortic to radial pressure gradient (ATRAP) is the cause of an underestimation of the aortic pressure with a measure assumed with a radial catheter, and he can concert 1 of 3rd patients. The risks factor well known are small height, previous hypertension, long and difficult surgery, radial artery diameter less than 1.8mm. The ATRAP definition is a pressure difference between radial and femoral (same of the aortic pressure) pressure of 25mmHg on the systolic pressure, or a pressure difference on the mean pressure of 10mmHg, both measures realised by arterial canulation, and with a duration superior than 5 minutes. If this gradient appears in pathophysiological specifics situations, there is a risk of inappropriate administration of vasopressors, with more hospitalisation days, more side effect of vasopressors like an augmentation of myocardial work. The ATRAP is documented in septic shock with a prevalence between 21% and 27%. The ATRAP can appear in shocks, moreover with doses of equivalent norepinephrine of 0.5 µg/kg/min who is use for the definition of refractive shock, the difference between the two pressure is higher if the dose of equivalent norepinephrine is higher than 1µg/kg/min. But the prevalence and risks factors are barely unknowns in this situation. Most of the time, a radial arterial catheter is used for hemodynamic monitoring for his simplicity of utilisation and the lows complications associated. Some medical teams in cardiac surgeries, or in intensive care unit (ICU) for the management of shocks used often radial and femoral arterial catheter. It seems there is no at risk for the utilisation of a radial and femoral arterial canulation. Out of the situation of cardiac surgery, there is a lack of information of the ATRAP, the objective of the study is to evaluate the prevalence of the ATRAP in shock, out of the situation of cardiac surgery.
A biopsy of a breast tumor lesion will be performed for processing to establish avatars (patient-derived organoids -PDO). A personalized tumorogram for each patient will be provided, based on the results of the drug screening (= tumor predicted as sensitive, intermediate, resistant or non-evaluable for each drug tested). Patients with an informative tumorogram will receive one of the recommended treatments (line N+1) in the event of tumor progression, administered according to standard procedures and validated at medical meetings specific to each center, and their fate will be monitored.
The aim of this feasibility, prospective, single-center trial is to compare an intra-oral Photobiomodulation (PBM) via the Caremin650TM device (NeoMedLight) and a transcutaneous PBM via the ATP 38® device (Swiss Bio Innov) in patients treated with radiotherapy or chemoradiotherapy for cancer of the oropharynx or oral cavity. PBM session will be carried out first at the rate of two sessions per week for preventive purposes, and then, in case of occurence of grade 1 mucositis, three sessions per week with curative purpose.
We propose to demonstrate that HIV-1 and SARS-CoV-2 are capable of targeting long-lived HSPC with self-renewal capacities. These progenitors, thus transformed into host cells, can give rise to a durable source of infected cells with an impact on hematopoiesis.
