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.
The aim is to evaluate the correlation between the respiratory control to hypercapnia at rest and the VE/VCO2 slope measured during cardiopulmonary exercise testing. The hypothesis is that patient with univentricular congenital heart disease have a increasing of respiratory drive like chronic heart failure. This increasing of respiratory drive could participate in the increasing of VE/VCO2 slope measured during cardiopulmonary exercise testing and in the genese of central apnea index during the sleep.
The pathophysiology of sepsis is characterized by the sudden onset of vasodilation and vascular permeability with capillary leakage. This leakage contributes to the development of generalized edema which is not clinically detectable below 4 litres but which becomes visible after a few days. The edema accumulates mainly at the subcutaneous level due to the high compliance of this tissue. Edema, and therefore hydrosodium overload, testifies to the severity of the inflammation. However, it could also be harmful in itself (affecting microcirculation and increasing mortality) as suggested by numerous clinical and experimental studies. The transfer of fluids between vascular and interstitial compartments during sepsis therefore has a central role in the pathophysiology of the disease and associated mortality. These transfers are mainly controlled at the microvascular level (with constant permeability) by the difference between capillary (CP) and interstitial (IP) pressures. In healthy subjects, subcutaneous IP is discreetly negative (-1 mmHg) and varies very little. On the other hand, a sometimes drastic decrease in IP has been described in various localized and systemic inflammatory situations. These pressure variations may be explained by the collagen structure of the interstitial tissue and a change in the three-dimensional conformation of these macromolecules induced by inflammation mediators. In an animal model of sepsis, a study showed significantly lower pressure in a group of animals in endotoxic shock. IP has never been measured in humans during sepsis. The objective of this study is to analyze subcutaneous IP (SCIP) in patients with septic shock compared with controls in order to evaluate the direct role of interstitial tissue in the onset of edema during sepsis.
Investigator have recently shown that Parkinson disease patients' with restless leg Syndrome have more frequent impulse control behavior in particular compulsive feeding that patients without Restless Leg Syndrome (RLS). Investigator hypothesized that presence of RLS in parkinsonian patients could be a risk factor for the emergence of TCI or associated behaviors, occurring preferentially at night. The main objective of this study is to evaluate in patients with idiopathic Parkinson's disease (IPD) the effect of the presence of a RLS on the evening compulsive eating behavior by studying the circadian modulation of food intake of patients with RLS and impulse control disorders. For this investigator conduct a prospective study, with 2 groups of Parkinson disease patients (with and without restless leg syndrome), to which investigator have to fill an agenda to know the schedule of the behaviors during the day and the night.
Lung Ultrasonography (US) has been shown to be effective for verifying endotracheal tube (ETT) position in adults and children but has been less studied in neonates. The aim of this study is to evaluate the performance of lung US in determining correct ETT position in neonates, in comparison with X Ray
This is a non-blinded, non-randomized controlled pilot study with no follow-up. Patients will be recruited from the coronary angiography patient pool of the American Hospital of Paris and assigned to one of 2 groups in a non-randomized manner.
The use of respiratory polygraphy (RP) in children for the diagnosis of obstructive sleep apnea hypopnea syndrome (OSAHS) can be challenging: device acceptance, sensors displacement. The automatic analysis of respiratory events has never been evaluated in a pediatric population. The primary objective of this study was to determine the feasibility of pediatric RP in an ENT department routine practice. The second objective was to evaluate the reliability of the automatic signal analysis in children.
Hepatitis B is one of the major public health problems in the world. According to World Health Organization (WHO) data, about 2 billion people have been in contact with the hepatitis B virus (HBV), and 257 million have chronic HBV infection. Although France is a low endemic country, with just over 280,000 people with chronic infection, hepatitis B remains a public health problem due to its morbidity and mortality. Drug users are a population at risk by their consumption practices (injection or sniffing), but also by other high-risk behaviours, particularly sexual behaviours. Prevention therefore involves securing consumption practices (sterile and single-use equipment) and protection of sexual intercourse, but also by vaccination (protecting more than 90%). Since 1982, HAS has recommended to systematically vaccinate drug users. However, according to the Marmottan study published in 2003, immunization coverage among drug addicts was already insufficient in 1999 (45.3%) and decreased again in 2000 and 2001 (15.6 and 21.7%). This decrease can be explained by the controversy around the potential link, now refuted, between vaccine against HBV and demyelination, which has stopped the mass vaccination campaign launched by the French health authorities in 1995. A study conducted between 2009 and 2012 on injecting drug users in Alsace, estimated vaccination coverage at 28%. The hypothesize is that despite the recommendations in a population at high risk of contamination, and a balance of benefits and risks in favor of vaccination, vaccination coverage against the hepatitis B virus remains insufficient among drug users because of poor vaccination acquaintance, and hepatitis B in general, in this population. Principal objective of this study is to identify non-vaccination factors against hepatitis B virus among drug users consulting at the Croix-Rousse CSAPA.
Retrospective, observational cohort study. Objectives : To search for correlations between socio-economical deprivation and oral health in french children of 9 years of age. To study the annual use of oral and dental care of children from 6 to 9 years of age depending on their geographical and socio-economical environment, and the medical demography ; To identify and study the share of the cohort not using oral and dental care, and the socio-economical and geographical factors implicated in this non-use of care. The study will use data from the french nationwide healthcare systems database (SNDS) and data from the french national institute of statistics and economic studies (INSEE).
AR-301 is being evaluated as an adjunctive treatment of ventilator-associated pneumonia (VAP) due to Staphylococcus aureus (S. aureus) in combination with standard of care (SOC) antibiotic therapy in patients with confirmed S. aureus infection.
Taxane neuropathy is a common and long-term side effect of long-term morbidity in patients surviving cancer. No preventive or symptomatic treatment has been shown to be effective. Its pathophysiology is poorly known and probably multifactorial. A possible mechanism would be mediated by the activation of the SK3 calcium channel: a retrospective study carried out at the University Hospital of Tours (Carina RUA) found a significant association between the number of CAG triplets in the KCNN3 gene coding for the SK3 channel and the appearance of a taxane neuropathy.
