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.
Hemp is a plant of the Cannabaceae family. Cannabis sativa, derived from female flowers, is the first illicit substance used by adolescents and is a major public health problem. Its psycho-active effects come from tetrahydrocannabinol (THC). Unlike recreational cannabis, industrial hemp derived from cannabis sativa has a high level of cannabidiol (CBD) but a negligible level of tetrahydrocannabinol. Its seeds are now consumed in various forms and generate increasing interest. Seeds have many nutritional benefits. It seems important to take an interest in hemp, given the recent expansion of medical cannabis and the increasing use of cannabis for recreational purposes. It is incriminated in various allergies (contact dermatitis, asthma, rhinoconjunctivitis) but also in the occurrence of anaphylaxis to certain foods by cross-allergy in atopic subjects, in association with an Lipid-Transfer Proteins (LTP protein), present in the flower of Cannabis sativa. Unlike the allergy to recreational cannabis, the allergenicity of hemp seeds is little studied. Hemp seed can cause severe anaphylactic reactions. In all reported cases, the prick-tests were positive for the seeds. Often, patients had never been in contact with hemp seeds but had already been exposed to cannabis by respiratory or manual routes. The investigators hypothesize that sensitization by the skin or respiratory route (cannabis smokers, passive exposure to cannabis, workers exposed to hemp, etc.) could lead to the development of a food allergy to hemp seed.
The factors of success of decannulation are not well known in the literature and the decision to decannulate is mainly based on clinical judgment. The failure rate of decannulation is between 2 and 25% with a poor prognosis in case of failure. The objective of this study is to determine the factors associated with successful tracheostomy removal in patients hospitalized in a respiratory weaning unit. The secondary objectives are to evaluate in tracheostomized and hospitalized patients in weaning unit: - The prevalence of successful tracheostomy removal; - The prevalence of successful weaning from mechanical ventilation; - Factors associated with successful weaning from mechanical ventilation; - Demographic characteristics of these patients at admission; - Ventilatory characteristics of these patients at admission; - Biological characteristics of these patients at admission; This is a prospective, single-centre, interventional cohort study with an expected duration of 2 years. All patients admitted to the respiratory weaning unit in the Forcilles' hospital, with a tracheostomy and an expected duration of mechanical ventilation > 48 hours will be consecutively included. All factors potentially associated with successful tracheostomy removal will be prospectively collected: severity factors related to the ICU stay, ventilatory factors, respiratory and extra-respiratory factors.
Prevalence of food allergy in the world has been inscreasing in recent years. Among nut allergy, hazelnut allergy is the most widespread in Europe and particularly in France. The current treatment for hazelnut allergy is based on eviction and wearing of an emergency kit with adrenaline auto-injector pens, to be used in the event of severe anaphylactic reaction. Oral immunotherapy (OIT) is a treatment that is now increasingly being offered as an alternatice to eviction. There are few published data concerning hazelnut OIT in Europe, where its consumption is nevertheless very high. The main objective of our study is to evaluate the clinical efficacy of the hazelnut OIT protocol, implemented since 2015 in the pneumology and allergology-paediatric department of the Mother and Child Hospital in Bron, in hazelnut allergic children under 18 years old. The secondary objectives will be to evaluate the biological efficacy and clinical tolerance of the protocol. The study is retrospective and observational, and is based on the collection of medical data from patient records.
Vascular dysfunction is an important mechanism involved in organ failure, in the setting of sepsis condition, with different types of circulating endothelial cells.Transcriptom analysis via RNAseq in different types of circulating endothelial cells, comapring critically ill patients with or without sepsis will allow determining differential gene expression for signal pathways in endothelial alteration and restoration associated with sepsis.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the coronavirus disease 2019 (COVID-19) affect at late march 2021 more than 127 millions of persons worldwide (including more than 4.5 millions in France, according to John Hopkins University https://coronavirus.jhu.edu/map.html, consulted 2021/3/25). Among these persons, 17% of the confirmed cases the COVID-19 develop an acute respiratory distress syndrome (ARDS) (Chen et al., 2020), requiring an hospitalization in intensive care unit with mechanical ventilation for prolonged periods (in median up to 21 days whereas 3.3 is the usual mean length of stay). This prolonged period of inactivity causes dramatical muscles and cardio-respiratory losses. These patients experience a dramatical decrease in the physical ability which is reinforce by the protective isolation measures and containment to prevent the further spread of the virus. Rehabilitation of patients with a severe form of the COVID-19 faced new challenges due to the novelty of the disease and protective isolation measures to prevent the further spread of the virus. Rehabilitation target a recovery of the cardio-respiratory, muscle deficits and improvement in activity. Functional electrical stimulation (FES) is one innovative technique, among other. FES have been shown as effective to improve the respiratory function in patients with a severe chronic obstructive pulmonary disease (Acheche et al., 2020; Maddocks et al., 2016), reduce the muscle loss due to zero gravity in space for astronauts (Maffiuletti et al., 2019), or increase strength in persons with incomplete spinal cord injury (de Freitas et al., 2018). FES has been recently delivered during cycling to restore pedaling movements with an adequate rhythm of muscle contraction. To date, FES cycling has been successfully administered in patients with spinal cord injury, and has been shown to be more effective in patient with severe COPD for improving the exercising intensity; reducing fatigue and improving quality of life in persons with multiple sclerosis (Backus et al., 2020). In a pilot study, we shown that 4 week of physical therapy incluing FES cycling resulted in a fasten recovery of active postures as compared to physical therapy including cycling alone. (Mateo et al., under revision). Therefore, we hypothesize that a 4-week period of rehabilitation based on physical therapy with FES cycling would result in a significantly increase of activity profile (decrease in inactive posture duration) in patient with a severe form of COVID-19 (i.e., with an ARDS requiring mechanical ventilation).
Miscarriage is the spontaneous termination of pregnancy before 22 weeks of amenorrhea. The most frequent complication of pregnancy, it represents 10 to 25% of pregnancies and affects one in four women. Miscarriage is considered by medical personnel to be common and trivial. however, for women, it is very often a traumatic event, a source of worry for futures pregnancies.
It is a prospective, monocentric, interventional study on spontaneous vaginal clearance of Mycoplasma genitalium. The main objective is to evaluate the spontaneous vaginal clearance of M. genitalium in patients coming to perform a voluntary termination of pregnancy at the University Hospital of Bordeaux at 9 weeks after a vaginal sample positive for M. genitalium
PSOBIOTEQ is a national multicentric prospective non interventional study which aims to constitute a French registry of cutaneous psoriasis patients initiating systemic treatment (excluding acitretin and phototherapy) for moderate to severe cutaneous psoriasis. The general objective of PSOBIOTEQ registry is to describe the use, benefits and risks of conventional, biological, biosimilar and small-molecule inhibitor of phosphodiesterase 4 (PDE4) systemic treatments in a real-life setting. The registry aims to meet many specific objectives and to fulfill ancillary studies. The PSOBIOTEQ registry concerns a largely similar population and has same objectives than the PSOBIOTEQ Cohort (NCT01617018). Indeed, data from the PSOBIOTEQ cohort will constitute the historical part of the registry and the cohort patients will pursue their follow-up in the registry framework, in order to enrich their follow up with new collected data.
This study aims to validate a difference in blood microbial signature between Alzheimer's patients and control subjects in order to propose potential innovative strategies
Neonatal pulmonary hypertension is a rare but serious condition resulting from a lack of adaptation to extra-uterine life in some newborns. In the short term, the risk of death requires rapid and appropriate management of this transient pathology. In the long term, these newborns present a greater brain vulnerability, a consequence of the pathology itself with cerebral hypoxia but also invasive and aggressive therapies. Although current scientific evidence indicates a correlation with the existence of neurological developmental disorders, the understanding of the long-term neurological outcome of these babies remains poorly documented. Better knowledge of remote neuro-psychomotor development of the critical period
