Clinical trials

Among children aged ≤ 6 months included in the ENVIE study, the ENVIE\_ancillaire study will be offered to cases of RSV infection or to controls. The study involves a nasopharyngeal swab using a FLOQ-SWAB™ swab and a fingertip sample (dextro type). These samples will be collected specifically for the purpose of studying immunity. A blood sample may also be requested for children weighing ≥5 kg who are included in the ENVIE\_ancillaire study. The purpose of this sample collection will be to conduct an advanced immunological study

The hypothesis behind the study is that the performance of constant flow CPAP (Continuous Positive Airway Pressure) devices (CF-CPAP) is not inferior to that of variable flow CPAP devices (VF-CPAP) in terms of respiratory efforts assessed by swing EAdi (Electrical activity of diaphragm) in a population of premature neonates born ≤ 32 weeks of gestational age.

PANTOXBIL is a research project developed in the context of the increasing incidence of biliary tract and pancreatic cancers in France. Despite recent therapeutic advances, the prognosis of these cancers remains poor. Known risk factors do not fully explain the increase in incidence observed over recent decades. This suggests the possible role of emerging occupational and environmental risk factors, as reported in several epidemiological studies. The PANTOXBIL study is based on the analysis of detailed curriculum laboris data (employment periods, occupations, tasks performed, and occupational exposures) collected during two multicenter phase II clinical trials, TEDOPAM and IMMUNOBIL, conducted between 2018 and 2021 in patients with pancreatic and biliary tract cancers. An occupational exposure assessment was performed to calculate semi-quantitative cumulative exposure indices for each exposure or group of exposures for every participant. These indices will be compared with those of healthy controls from the CHOPPI cohort, initially designed to study occupational risk factors in COPD. PANTOXBIL is a matched case-control study based on sex, age, and smoking status. The aim is to compare cumulative occupational exposure indices between cases and controls in order to generate new hypotheses regarding occupational risk factors for biliary tract and pancreatic cancers.

Adult patients referred to the ENT surgery department of the Hospices Civils de Lyon with cholesteatoma that had never been operated on. All patients will benefit from surgical management for cholesteatoma initially in the operating room under general anesthesia. The surgical technique (closed technique) is the reference technique for the management of cholesteatoma in adults. It involves a cartilaginous removal to reconstruct the attical region. Then a filling material is used to fill the mastoid (GlassBONE™ or Bonalive™), and above all to stabilize the cartilaginous fragment to prevent a recurrence.

COPD and non-COPD patients will be included in the study after collection of their non-objection. The exhalation will be collected to study the microbiological diversity of human exhalations. a second collection for the year +1 will be made, at the same time (between October and March).

Retinal vascularization in humans develops between the 16th and 36th weeks of amenorrhea, in a centrifugal pattern starting from the optic disc. In the case of premature birth, the immature peripheral retina is at risk of ischemia due to incomplete vascular development. Prematurity is often associated with respiratory fragility. It frequently requires ventilatory support in the form of oxygen therapy, either invasive (orotracheal intubation) or non-invasive, which induces reflex arteriolar vasoconstriction, thereby worsening the existing ischemia. This raises the question of whether subclinical retinal vascular changes, detectable by OCT angiography, may explain the increased risk of amblyopia and the need for optical correction observed in these patients. OCT angiography is rapidly expanding in the field of retinal vascular diseases: it is a simple, fast, reliable, and non-invasive examination, requiring no injection, that enables high-resolution visualization of retinal vascularization, with separate analysis of the retinal plexuses and the choriocapillaris.

This study examines care pathways in 300 patients with anal squamous cell carcinoma to identify barriers and delays in diagnosis, assess the impact of screening and access to care, and improve awareness, screening practices, and early diagnosis.

The study hypothesis is that dilations of idiopathic bronchi are particularly common in French Polynesia, and that there are arguments in favour of an underlying genetic factor. The study will retrieve retrospective data in the history of bronchial dilation, patients' personal and family history, microbiological and scannographic data, and the latest cardio respiratory checkup.

A randomized clinical trial to assess the efficiency of acetylsalicylic acid (aspirin) 150 mg/day started before 20 weeks of gestation in the prevention on maternal and fœtal complications in pregnant women with chronic hypertension.

Preeclampsia and intrauterine growth retardation (IUGR) are serious and frequent pathologies, specific to pregnancy. They represent 70 000 new cases a year, or 9% of pregnancies and cause 50,000 premature births per year in France. The consequences in terms of morbidity and perinatal morbidity and the medical and economic costs make it an issue public health. Pre-eclampsia associates maternal hypertension with dysfunction kidney. There is no cure for pre-eclampsia or IUGR vascular during pregnancy. These pathologies invariably evolve towards a maternal and / or fetal aggravation sometimes very fast. Primary prevention and secondary education and screening for these pathologies are still insufficient. A better understanding of the pathophysiology of these placental vascular pathologies is necessary for the development of supported medical, obstetric and pediatric that will improve the state of health maternal and neonatal

Prospective, multicenter, non-interventional study conducted over 6 months, including patients presenting to the emergency department with suspected urinary tract infection managed as outpatients and discharged with or without empiric antibiotic therapy. Discharge antibiotic prescriptions are reviewed, with subsequent reassessment and optimization of treatment based on urine culture and susceptibility results

In France, cervical cancer is the 12th most common female cancer with nearly 3,000 new cases per year. Since 2018, a national Organized Cervical Cancer Screening program (DOCCU) has been set up and concerns all asymptomatic women aged 25 to 65. This program, managed by the Regional Cancer Screening Coordination Centers (CRCDC), invites women who have not taken a sample within the recommended time frame to consult for screening. However, only 59% of patients participated. The intervention of the general practitioner, an essential player in prevention, could allow for better awareness. The objective of the INDIGO study is to evaluate the effectiveness of the intervention of a general practitioner on the participation rate in the DOCCU of patients who are not up to date with their screening.

The aim of this study is to evaluate the use of a fixed dose of 3.66 mcg of follitropin delta (Rekovelle) on ovarian response during ovarian stimulation for intrauterine insemination (IUI). The assumption is that this fixed dose will be effective while minimizing the risk of multiple pregnancies. A recent study demonstrated the efficacy of follitropin delta for ovarian stimulation in IUI, and it has been approved in France for controlled ovarian stimulation in assisted reproductive techniques such as in vitro fertilization (IVF) and IVF with intracytoplasmic sperm injection (ICSI). With an adapted dose of Rekovelle for patients with regular menstrual cycles, ovarian stimulation is optimized from the first attempt, promoting the development of two follicles to improve pregnancy chances while reducing the risk of multiple pregnancies. This approach aims to achieve pregnancy faster and provide a more comfortable treatment experience.

Despite the increasing use of non-invasive ventilation, a large majority of premature neonates still receive invasive ventilation during their NICU (neonatal intensive care unit) stay. Invasive ventilation is a unanimous source of discomfort and pain. As opposed to the adult and pediatric population, routine use of opioids or midazolam is not recommended in ventilated neonates. Although opioids are the most frequently prescribed analgosedative drugs in ventilated premature neonates, their use is controversial because of the risk of respiratory depression - which can prolong invasive ventilation- and concerns on long-term neurodevelopment. Dexmedetomidine, a selective alpha-2- adrenergic agonist routinely used in the adult ICU (intensive care unit), provides light sedation and some analgesia with no or little respiratory-depression effect. It also has neuroprotective properties after pediatric cardiac surgery and in neonatal animal models. Dexmedetomidine is thus a promising candidate drug in ventilated premature neonates that might reduce the duration of mechanical ventilation and preserve neurodevelopment in this vulnerable population. The investigators hypothesize that the use of dexmedetomidine in ventilated premature neonates could decrease the need for opioids, facilitate extubation and thereby preserve long-term neurodevelopmental outcome.

Adult patients consulting the gynecological emergency department of CHI Créteil during the inclusion period for endometriosis or symptoms suggestive of endometriosis

The purpose of this observational study is to learn about neonatologists' perceptions of extubation readiness and extubation and reintubation practices in extremely preterm infants in the first 2 weeks of life using prospective qualitative and quantitative data. Actual extubation readiness is defined as successful extubation, defined as no reintubation in the 7 days following extubation. Key research questions are: How do clinicians assess extubation readiness in this population? Does this assessment correlate with actual extubation success? What factors (reasons, clinical status, ventilatory parameters) are associated with extubation readiness? Patients born before 28 weeks gestational age and admitted to the neonatal intensive care unit (NICU) within the first 24 hours are be included. The attending physician will complete a prospectively administered questionnaire with open-ended and multiple-choice questions to daily assess the decision and rationale for extubation or non-extubation of patients mechanically ventilated during the first 15 days of life. Patient characteristics, respiratory outcomes, and mortality will be recorded until the end of hospitalisation and/or definitive weaning from any ventilatory support or supplemental oxygen.

Patients having the following gestures (blood test, change of dressing for cancerous lesion and complete toilet in bed) will be identified by the team of the medical oncology department. During the first contact (V0), the study will be presented to the patients in order to obtain their consent. Anxiety and well-being will be assessed before performing the gesture causing discomfort (gesture No.1). The gesture will then be performed and the patient's comfort will be evaluated after the gesture is performed in order to obtain the starting data for the study. Patients will be reviewed in consultation according to the time recommended for each type of gesture. During the second contact V1 (between 1 and 9 days after D0) anxiety and well-being will be assessed before performing the gesture causing discomfort (gesture No.2). Patients will then be randomized. After randomization, the first hypnosis session will be performed at the same time as gesture No. 2 and the patient's comfort will be evaluated after the gesture is performed. The patient will receive the self-hypnosis training on the same day. A period of 7 ± 2 days will be considered for the learning time of self-hypnosis. The third contact will take place on day D7+/-2 after V1. During this visit, anxiety and well-being will be assessed before performing the gesture causing discomfort (gesture No.3). Gesture No.3 will be carried out under the effect of self-hypnosis ± aromatherapy and the measurement of comfort will be carried out immediately afterwards

In recent years, the average length of stay in maternity units has decreased, leading to the development of early postnatal discharge home (EPDH) programs. Postnatal follow-up is a major public health issue, as it supports the physical and psychological well-being of mothers and newborns, helps parents adjust to their new roles, and promotes health prevention and education. International studies show that mothers expect longer and more comprehensive follow-up, particularly regarding child development, sexuality, contraception, and returning to work. In France, EPDH has existed since the early 2000s and is offered to low-risk mothers and newborns shortly after birth, with two or three follow-up visits at home or in healthcare facilities. As these programs are expected to expand, there is a need to better understand the experiences and needs of both mothers and healthcare professionals. This qualitative study, conducted in the Val-de-Marne department, aims to explore how they experience early discharge at individual, organizational, and medical levels. It seeks to identify the factors that contribute to positive or negative postnatal experiences and to compare local findings with existing international research.

National multicentric registry of a cohort of patient with suffering parietal endometriosis, carried out by a multidisciplinary radiosurgery team

This study aims to describe a dose-effect relationship of morphine alone and morphine and midazolam administered as continuous infusion in neonates hospitalized in Neonatal intensive care unit and undergoing mechanical ventilation, through PKPD modelling.

Purulent Oedematous Sinusitis (POS) is a particular form of chronic rhinosinusitis observed in 2% of the general population. In spite of its heavy impact on the quality of life, There is no established recommendation for the treatment of primary POS. Long-term low-dose macrolides are currently proposed for these forms of chronic rhinosinusitis when conventional treatments (local corticosteroids, saline rinsing, iterative short courses of antibiotics targeted on pathogens, and surgical opening and drainage) have failed. This treatment with macrolides is currently applied off-label. This study aims to assess the efficacy of macrolides in POS. An extensive workup is fulfilled to exclude other forms of chronic rhinosinusitis (Th2 biased inflammatory diseases, allergic diseases) (allergy, nasosinusal polyposis) or those due to cystic fibrosis or immune deficiency.

To evaluate the regenerative capacities of mesenchymal cells composing the microenvironment of alveolar type 2 cells in a population of patients, undergoing thoracic surgery for suspected cancer, who are smokers with and without COPD compared to non-smokers patients

The emergence of extended-spectrum beta-lactamase-producing Enterobacteriaceae (E-ESBL) is a major public health problem. It leads more frequent prescription of penems with the risk of emergence and spread of strains producing carbapenemases, which may be resistant to all known antibiotics. A policy of savings of penems is desirable. Among the alternatives to penems, amikacin is in the foreground. It remains active on the majority of E-ESBL strains. Some risk factors for E-ESBL emergence are known: recent antibiotic therapy (particularly quinolones and cephalosporins third generation), previous hospitalization or residence in a high endemic country. In pediatrics, E-ESBLs are primarily responsible for urinary tract infection. In France, E-ESBLs represent about 10% of the strains responsible for urinary tract infections. The Pathology Group Pediatric Infectious (GPIP) of the French Society of Pediatrics (SFP) and the Society of Infectious Pathology French Language (SPILF) have proposed different therapeutic options to treat febrile UTIs in children: amikacin intravenous; intravenous (IV) ceftriaxone or intramuscular (IM); or cefixime per-os (PO). The objective of this study is to compare the emergence of E-ESBLs in stools of children after febrile UTIs treatment with amikacin IV versus ceftriaxone or cefixime.

This is an observational prospective monocentric study which aims to compare operative hysteroscopies performed in the operating room under general or loco-regional anesthesia and those performed outside the operating room (outpatient operative hysteroscopy). The primary outcome is the success rate of the procedure. Secondary outcomes include postoperative pain, patient satisfaction, complications, and time to return to work.

Chronic airways infection with Pseudomonas aeruginosa (PA) is associated with increased frequency of exacerbations, deterioration in quality of life and increased mortality in adult patients with bronchiectasis. Current guidelines suggest the prescription of an eradication antibiotic treatment for a first episode of PA infection (early PA infection). Several antibiotic regimens may be proposed, ranging from a monotherapy with oral fluoroquinolone (FQ) to an intravenous cotherapy with the addition of inhaled antibiotics that seems to improve the rate of PA eradication. As no study strictly favoured one regimen, current practices are heterogeneous and could certainly benefit from stronger evidence, with both medical and economic impact.
