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.
Adaptive immune responses are essential for clearing viral infections and retention of virus specific memory populations is required for long-term immunity. However, there is still uncertainty about whether adaptive immune responses to SARS-CoV-2 are protective. Such knowledge is of immediate relevance, as it will provide insights into immunity of SARS-CoV-2 infection and thus help define future immunization strategies. Because of the importance of asymptomatic cases in children, a specific study is needed in this population in order to determine their individual and collective protective capacity. This is even truer for immune compromised children that likely have severe forms of the disease with active and prolonged viral replication in whom it is therefore essential to determine the extent of sero conversion but also the quality and duration of the memory responses. For this purpose, we plan to analyze the anti-SARS-CoV-2 humoral and memory T cell responses, in different groups of immuno-compromized children (i.e with different levels/type of immunosuppression; HIV, renal or stem cell transplantation, anti-TNF or methotrexate treatment) and healthy controls seen in 3 University Hospitals, in order to determine the proportion of children with SARS-CoV-2 specific humoral responses, their protective capacity, the magnitude and the quality of the SARS-Cov-2 memory T cells but also their long term persistence at 1 year.
The management of cerebral infarctions (CI) is a real public health issue. The French National Authority for Health recommends Mechanical Thrombectomy (MT) either in combination with Intravenous Thrombolysis (IVT), or alone, after failure of IVT or in case of contraindication to IVT, within 6 hours of the onset of symptoms. The objective is to determine the factors predicting good functional recovery at 3 months in order to establish the typical profile of the "good responder" patient to MT and to evaluate functional recovery at 3 and 12 months (mRS ≤ 2) according to the modality of MT (depending on whether it is performed during the day or at night), the age of the patients, the equipment used for MT, the type of anaesthesia, as well as the impact of the metrics from the radiological evaluation in the patient's management. patient management.
Promising results of an early EMDR (Eye Movement Desensitization and Reprocessing) intervention on PCLS (PostConcussion-Like Syndrome) at three months have been shown, suggesting that the availability of psychological care in emergency departments will be useful. The real impact of such a care service remains to be measured. Several factors may modulate the impact of such a measure, leaving the extent of its public health benefit uncertain. In the SOFTER III trial, the results suggest that high levels of self-rated stress at admission probably play a key role in the development of CPSP and psychological intervention. The most appropriate study design for such an objective is to follow a cohort of patients in the Emergency Department and to assess the main risk factors for CPSD 4 months later. To this end, all consecutive patients should be asked to participate in a study and complete a risk factor questionnaire, regardless of their level of risk for CPSD. SOFTER IV offers the opportunity to evaluate the impact of a psychological intervention to reduce the incidence of chronic pain. By acting on the emotions experienced in the Emergency Department, a reduction in acute pain and perhaps in the longer term in chronic pain can be expected. Its psychological aspects, and more specifically the emotional dimension, are known to be related to acute pain. As for the relationship with chronic pain, it exists, but its meaning is not clear because the emotional state is assessed when the pain has already become chronic. It is proposed to integrate the assessment of emotions at inclusion in the project, and to follow up patients 12 months after inclusion to assess the incidence of chronic pain and identify the factors that modulate it. Early intervention in the emergency department, including an early short one-hour EMDR intervention R-TEP (Recent Traumatic Episode Protocol), could thus reduce the incidence of chronic pain.

Background The presence of the Covid-19 virus has been detected in tissues of various origins: nasopharyngeal swabs, sputum, bronchoalveolar fluid, blood, stool and anal swabs. However, it does not appear that the virus is excreted in the urine. The REACTing group (Research & Action Emerging Infectious Diseases) has demonstrated the presence of the virus in the conjunctiva and pleural fluid. This detection was made possible by carrying out quantitative, real-time RT-PCR and sequencing of the viral genes, which are currently the benchmark for the diagnosis of COVID-19. However, it is not known at this time whether the Covid-19 virus is present in joint fluid or in bone. However, some viruses have a particular bone tropism (Parvovirus B19, HHV6); others have joint tropism (parvovirus B19, HBV, HCV, rubella, HIV, HTLV-1). The presence in "orthopedic" tissues of the various coronaviruses (MERS, SARS, etc.) has never been evaluated in the past. However, cases of pulmonary contamination by coronavirus after bone marrow transplantation have been reported in the literature. A potential location at these levels could cause problems of different kinds. Rationale First, and concretely, a possible direct transmission by these tissues. The current English and Spanish national recommendations in orthopedics show a controversy as to the risk of intraoperative contamination during medical procedures generating aerosols, in particular those involving instruments at high speed (saw blade, reamer, drill). This transmission could also be a problem during bone marrow transplants, from the iliac crests, for example. Second, but hypothetically, Covid-19 could become quiescent at the level of the myelo-hematopoietic niches and reactivate at a distance, which could then explain the current interrogation on "absence of immunity" and cases of early revival in patients considered cured. This hypothesis is all the more likely since, always by analogy with Parvovirus B19 or HHV6, a recent alert on cases of myocarditis in children has been issued in Parisian pediatric hospitals and that treatment with tocilizumab, which blocks the action Interleukin 6 receptors, and initially used for joint manifestations of rheumatoid arthritis, appear promising.
Nursing home staff face multiple stresses during the Covid-19 pandemic including personal risk of infection, risk of transmission of the virus to residents and relatives, and risk of witnessing end-of-life scenarios under difficult contexts (absence of families). The hypothesis of this study is that the Covid-19 period is associated with an incidence of more than 30% of post-traumatic stress in nursing home staff.
Today, prosthetic replacement for osteoarthritis of the knee is a frequent surgery. In France, nearly 100,000 knee arthroplasties are performed each year . Over the last two decades, there has been growing interest in performing single compartment knee replacement (SKR) surgery in patients with isolated single compartment osteoarthritis. The explanation lies in faster recovery, less postoperative pain and less morbidity compared to total knee arthroplasty (TKR) . Pain control is one of the major elements of outpatient management of CKD . Prosthetic knee surgery is very painful, the median pain is rated at 5 out of 10 and on average we use 32 milligrams of morphine . The efficiency of the adductor canal block is effective in this context, it avoids the motor block obtained by the femoral block, therefore interesting for ambulatory management in view of a resumption of the fast walking foreseen for the patient. The IPACK (interspace between popliteal artery and the capsule posterior knee) is designed to block the small sensory branches of the sciatic nerve that pass through this space without affecting the motor components. The IPACK block provides analgesia only for the posterior knee and would probably be ineffective alone for postoperative analgesia It is therefore often performed with an adductor canal block for multimodal analgesia. This block is performed in several facilities, and data are increasingly emerging on its effectiveness . Thus, based on the recommendations of the French Society of Anesthesia and Resuscitation, on improved rehabilitation after heavy orthopedic surgery on the lower limb published in 2019 the objective of this study is to evaluate the relevance of a protocol concerning prosthetic knee replacement (PUC) in ambulatory care, based on optimized pain control.
Colorectal cancer (CRC) is diagnosed in one million patients each year worldwide and is the 2nd leading cause of cancer death. Peritoneal metastasis (MP) is seen in 10% of CRC patients and is the metastatic site with the worst prognosis. Complete cytoreduction surgery (CCS) is the only treatment that allows for prolonged survivals. Five-year overall survival (OS) after CCS ranges from 30% to 60% compared with 0 to 5% with exclusive medical treatment. Chemotherapy (CT) with fluoropyrimidine and oxaliplatin and/or irinotecan 3 months pre-operatively and 3 months adjuvant is widely used. The benefits of perioperative CT have been demonstrated in another resectable metastatic site, the liver and has become by extension a therapeutic standard in France for CRC MPs. However, the impact of delay in the initiation of surgery and adjuvant or neoadjuvant CT is unknown for CRC MPs. Several deleterious oncologic effects are related to a long period without treatment between - Neoadjuvant chemotherapy and surgery: - Surgery and adjuvant chemotherapy. Several meta-analyses have demonstrated, for at least 13 different cancers, a continuous association between delays in treatment (CT, radiotherapy, or surgery) and cancer mortality. For CRC, Hanna's meta-analysis showed that for every 4-week delay in adjuvant surgery or CT, the risk of cancer death increased by 6 and 13%, respectively. These long delays between CT and excisional surgery also decrease survival in patients with liver metastases from colorectal origins and MPs from ovarian origins but this has never been evaluated in patients with MPs from colorectal origins. Demonstrating an oncologic impact of therapeutic delays would have several strategic practical impacts such as: - Promoting pre- and post-operative rehabilitation programs to facilitate recovery and reduce time to retreatment. - To use more easily techniques (protective stoma, multi-stage surgery) limiting the risk of complications and therefore the delays in treatment. - Propose clinical research protocols aimed at reducing these delays with knowledge of plausible statistical hypotheses. A therapeutic strategy of shortening the time between each treatment therefore deserves to be evaluated in metastatic forms of colorectal cancer. The investigators would like to evaluate the hypothesis that shortened time between treatments could have a prognostic impact on recurrence-free survival.
The Coalition on Psychiatric Emergencies (CPE) stressed in 2016 that emergency providers were increasingly recognizing the important role of the Emergency Department (ED) in reducing adverse outcomes associated with untreated with substance abuse liaison department (SUDs). Additional research is required to close identified knowledge gaps and improve care of ED patients with SUD. Of the more than 4.5 million ED visits in 2009 in US for drug-related causes,34-32% involved alcohol use alone or in combination with other drugs. Few studies investigated the clinical characteristics of patients referred to an addiction liaison department in a general hospital. The present study will be retrospective in a sample of 700 patients consecutively admitted for addictive behaviors in the emergency department and in the Medicine or Surgery departments of the Amiens University Hospital Center, France.
