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 transport of biological samples is a key step in the pre-analysis process in health facilities and must meet quality requirements (NF:EN:ISO 151989) to ensure that samples are transported in are transported in good conditions. Still in the experimental stage, drone-based air transport is participating in the aeronautical revolution of the development of unmanned aircraft on board in all areas of society, including health. This first project, led by the Biology Centre and the INNOVABIO Biological Resources Centre of the CHU de CAEN in collaboration with the company Delivrone, will allow to evaluate the feasibility in real condition of the mode of transport by drone versus transport of reference on the quality of a varied panel of medical biology examinations (biochemistry, hematology and haemostasis), on the safety of people (potentially infectious samples), on the control of the delivery time, on the control of the transport temperature (15-25°C ). The samples will be taken on 30 healthy volunteers with a total panel of 23 blood tests performed.
Post-thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis (DVT). The endovascular recanalization and stenting technique has become the gold standard treatment for medically resistant and disabling PTS. Stent thrombosis is a significant complication of this procedure; the risk factors for thrombosis are poorly understood. Monitoring the patency of the stent is a key component in maintaining clinical success. Doppler ultrasound is the first-line diagnostic tool for monitoring patients with venous stents, and has the potential to allow accurate assessment of venous stent obstruction. Absence of validated morphological and hemodynamic echodoppler criteria for the follow-up of these stents. • Main objective: Clinical and hemodynamic results of venous recanalisations by stenting in the chronic phase • Secondary objective (s): - External validation of hemodynamic criteria proposed in the literature to detect venous stent obstruction - Risk factors for venous stent restenosis
Central vascular access devices are required for home parenteral nutrition (HPN). There is few data available concerning their complications in adult HPN patients, and the potential link between venous thromboembolism and catheter infection is not well established. The aim of this prospective cohort study is to compare the incidence rate of catheter related complications among 3 types of central vascular access: peripherally inserted central catheters; tunneled catheters and port-a-cath devices, in adults patients on HPN; describe the risk factors, and identify a potential link between venous thromboembolism and infection. More than 300 patients will be consecutively enrolled and followed up from the time of catheter insertion until its removal. Venous complication (identify by an ultrasound examination if deep vein thrombosis is suspected), infection related to catheter and mechanical complications will be analyzed. The incidence of complications will be expressed per 1000 catheters-day and or as a percentage of total catheter.
Cystic fibrosis is the most common serious genetic disease in Europe. It is a multi-disciplinary disease, causing multiple organ damage. It is a painful disease and a source of anxiety and depression. The aim of this study is to assess the link between pain experienced during care and anxiety in children aged over 8 with cystic fibrosis.
Immune-checkpoint inhibitors (ICIs) have radically changed the therapy of cancer in recent years. ICIs promote antitumor immune response inhibiting one of the following immune checkpoints: cytotoxic T-lymphocyte antigen-4 (CTLA-4; ipilimumab), programmed death-1 (PD-1: pembrolizumab, nivolumab, and cemiplimab), and programmed death ligand-1 (PD-L1: atezolizumab, durvalumab, and avelumab). Despite the desired effect as cancer treatment, ICIs can break immune tolerance to self-antigens and induce specific toxicities known as immune-related adverse events (irAEs), that may affect both peripheral and central nervous system (Neurological immune mediated adverse events, NirAEs). The pathogenic mechanisms underlying NirAEs are probably heterogeneous, as reflected by the variety of clinical phenotypes and severity. NirAEs are rare, but there is some concern that the incidence may increase in the next future, in particular because ICIs are being used more and more for cancers commonly associated with paraneoplastic neurological syndromes (e.g. small-cell lung cancer). Moreover, NirAEs are usually severe, and often fatal. Indeed, irAEs-related complications are the most common cause of death among these patients. On the other hand, these patients usually have a good tumor response to immunotherapy. There is some evidence that irAEs may predict ICIs efficacy and consequently NirAE surivors are likely to have longer life expectancy than non-NirAE patients. Therefore, it is of utmost importance to better characterize the long-term outcomes of NirAE patients in terms of neurologic disability and mortality, and to identify predictors of severe NirAEs. So far, only few studies with sufficient follow-up have been published on the topic, and they included only small number of patients. The aims of our study is to characterize the main clinical and paraclinical features of NirAEs in a large cohort of NirAE patients, to assess long-term outcomes and to identify prognostic factors. This study will help define new guidelines regarding NirAE prediction and management.
Antistaphylococcal penicillins are recommanded as first-line agent in methicillin-suceptible Staphylococcus aureus bacteraemia. Several studies in progress are investigating the efficacy and safety of cefazolin compared with antistaphylococcal penicillins. Cefazolin has broader spectrum than antistaphylococcal penicillins. The hypothesis of this project is that cefazoline could be responsible for a higher rate of bacterial resistance. The aim is to study the association between the emergence of bacterial resistance and the consumption of cefazolin and antistaphylococcal penicillins.
This is a retrospective study on bladder cancer in French painters' population. The French agency ANSES collected data from all occupational and environmental diseases center in a specific database called RNV3P. We selected cases of bladder cancer in painters in four centers from 01/01/2010 to 31/12/2019. Those cases were analyzed in terms of occupational exposure, histology and sociodemographics data. Comparison between different histologic types of cancer, workplaces and occupational diseases process will be done.
Extranodal extension (ENE) refers to the spread of head and neck squamous cell carcinoma (HNSCC) outside the lymph nodes. It is a well-known factor that indicates a poorer prognosis and outcome for patients who have undergone surgical removal of the cancer. In such cases, it is recommended to combine chemotherapy with radiation therapy after surgery. As the number of cases of HNSCC related to the human papillomavirus (HPV) is increasing, treatment approaches have shifted towards using radiation therapy as the primary treatment method instead of surgery. This raises an important question about the significance of ENE observed through imaging tests (referred to as iENE) and its impact on the prognosis. Unfortunately, this question remains unanswered. The objective of this project is to conduct a comprehensive study across multiple medical institutions. The investigators will gather data including scan results, histopathology reports, and data from patient charts from individuals who have been treated for head and neck cancer. The aim is to analyze and correlate the findings between the pathological evidence of ENE and the imaging results, while also assessing the prognostic value of iENE. Additionally, the investigators will explore the influence of HPV status on these factors. By collecting and analyzing this data, the investigators hope to establish standardized criteria that can assist radiologists in accurately identifying ENE through imaging tests. This research is essential for enhancing our understanding of HNSCC and improving the effectiveness of diagnostic procedures and treatment planning.
This is an observational, retrospective pharmacovigilance study based on reports registered and transmitted in VigiBase®, the WHO's international database. This study includes all reports identified as exposure to an ICI and suspect of inducing adverse drug reaction. The aim of the study is to characterize immune-related adverse reactions associated with immune-checkpoint inhibitors, particularly their time-to-onset, co-occurence, factors associate with their over-report and fatality.
