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.
DMEK (Descemet Membrane Endothelial Keratoplasty) is a surgical technique used to treat primary or secondary corneal endothelial decompensation. At the Rothschild Foundation, as in many Western referral centers, DMEK is currently the surgical technique of choice for the treatment of primary or secondary corneal endothelial decompensation. Technically challenging, it is a relatively tedious surgery to learn, but offers the best visual and refractive results, as well as faster visual and functional recovery in simple cases. In patients without anterior or posterior segment surgical history, the complication rate of DMEK, including graft rejection, is similar to that of other endothelial keratoplasty surgical techniques. However, in specific cases, in patients with a history of ophthalmological surgery such as vitrectomy, trabeculectomy, large iris defects, anterior synechiae, aniridia or aphakia, the scientific literature shows a higher complication rate for DMEK (increased rate of rebulling and graft decompensation). As a result, other techniques that are less effective on visual results continue to be used for these patients in a large number of centers. Nonetheless, in our department, DMEK is also performed on these complicated patients. When it comes to patients with a history of anterior or posterior segment surgery, it seems to us that the surgeons' experience with DMEK allows better visual results than with any other technique, but without any back up regarding the complication rate in the literature. The main aim of this study is to describe, in patients with a history of anterior or posterior segment surgery undergoing DMEK, the 12-months occurrence rate of at least one serious post-operative complication.
The primary purpose of the study is to evaluate the efficacy of brensocatib at 10 and 40 milligrams (mg) once daily (QD) compared with placebo in improving clinical symptoms of CRSsNP.
This is a post-marketing surveillance on MiniMAX Stem
This clinical trial is studying nonsquamous non-small cell lung cancer (NSCLC). Participants in this study must have cancer that has spread through their body or can't be removed with surgery. Participants in this study must have been treated with no more than a platinum-based chemotherapy and an anti-PD-(L)1 drug. Participants with tumors that have certain treatable genomic alterations must have had at least 1 drug for that genomic alteration, in addition to platinum-based chemotherapy. This clinical trial uses an experimental drug called sigvotatug vedotin (SGN-B6A), which is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial also uses a drug called docetaxel. Docetaxel is an anticancer drug that has been approved to treat non-small cell lung cancer. It is usually given to patients who previously received another anticancer treatment. In this study, one group of participants will get sigvotatug vedotin on Days 1 and 15 during each 28-day-cycle. A second group of participants will get docetaxel on Day 1 during each 21-day cycle. This study is being done to see if sigvotatug vedotin works better than docetaxel to treat participants with NSCLC. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.
Periodontitis is a major public health problem because it is widespread in the adult population. It leads to the irreversible destruction of the anchoring tissues of the teeth, and represents a modifiable risk factor for systemic inflammatory pathologies. This chronic inflammatory disease, which is associated with oral dysbiosis involving Porphyromonas gingivalis, is triggered by a permissive immune response. It is preceded by a reversible clinical phase, during which there is no bone resorption process: gingivitis. The understanding of the key mechanisms involved in the evolution from gingivitis to periodontitis, which will allow to early identify patient at risk of periodontitis, remain unclear at this time. Neutrophils are the main cells of inflammation present within the periodontal pockets. The excess of certain neutrophils or the alteration of their functions is associated with the triggering of periodontitis, whereas their activity, finely orchestrated, would be a key to periodontal homeostasis. It is likely that some periodontal bacteria, including P. gingivalis, but also products of matrix catabolism could deregulate the physiological functions of neutrophils towards pro-inflammatory and catabolic profiles. Moreover, to date, the differentiation and role of neutrophil subsets in periodontal homeostasis as well as in gingivitis and its evolution into periodontitis remain poorly studied. The investigators hypothesize that various subsets of neutrophils may play different roles during the development of periodontitis (evolution of gingivitis to periodontitis). The primary objective is to characterize neutrophil subtypes associated with periodontal destruction during periodontitis. Secondary objectives are : 1. Identify specific interactions of tissue-activated neutrophils with the matrix microenvironment during periodontitis 2. Identify specific interactions of tissue or oral (salivary) activated neutrophils with the oral microbiota during periodontitis 3. Identify specific oral (salivary) neutrophil subtypes in periodontal health, gingivitis and periodontitis 4. Evaluate the function, including pro-osteoclastogenic function, of oral neutrophils compared to blood neutrophils stimulated by infection
The prevention of chemotherapy-induced alopecia (CIA) is still imperfectly managed in France. Strengthening the evidence base on the benefits of strategies to prevent CIA, based on robust methodologies, remains a prerequisite for better integration of appropriate supportive care for patients receiving chemotherapy. This research should provide new knowledge on the benefits of scalp refrigeration during anthracycline- and taxane-based chemotherapy in preventing ACI, for each of the 2 refrigeration techniques. In addition to effectiveness in preventing ACI, quality of life, self-image and satisfaction with care will be assessed by patients during and after chemotherapy. The medico-economic aspects will also be assessed for each of the two refrigeration modalities. The results of the various proposed assessments will be used to guide the choice between these two techniques for preventing ACI.
Chiari malformation corresponds to the herniation of cerebellar tonsils into the foramen magnum resulting in obstruction of cerebrospinal fluid circulation, which may eventually lead to the formation of an intramedullary cavity called syringomyelia. Chiari and syringomyelia can be responsible of variable symptoms, based on which neurosurgeons might propose surgical treatment. Yet, there is no properly developped and validated patient reported outcome measure (PROM) to assess the clinical severity of Chiari malformation and/or syringomyelia. The lack of such evaluation tool is a major issue to determine the optimal therapeutic strategy and to achieve a standardized and reproducible follow-up.
Goal directed fluid therapy (GDFT) or "Personalized fluid therapy" may benefit high-risk surgical patients but these strategies are infrequently implemented. It has also been shown that without any goal or protocol for fluid resuscitation, large inter- and intra-provider variability exist that have been correlated with poor patient outcomes. Recently, an "Assisted Fluid Management" (AFM) system has been developed to help ease some of the work associated with GDFT protocol implementation. The AFM system may help increase GDFT protocol adherence while leaving direction and guidance in the hands of the care providers. This artificial intelligence-based system can suggest administration of fluid boluses, analyse the hemodynamic effects of the bolus, and continually re-assess the patient for further fluid requirements. To date, there are no large outcome study using this AFM system. The primary objective of this trial is thus to evaluate the impact of this AFM system to guide fluid bolus administration on a composite of major postoperative complications in high-risk patients undergoing high-risk abdominal surgery.
The purpose of this study was to determine the impact of design on plate position at the level of the distal radius. Six anterior wrist plates design were analyzed relative to the watershed line using the Soong classification. A total of 2723 anterior locking plate fixation cases were analyzed and divided into six groups: Zimmer Biomet, Newclip Technics, Stryker, Synthes, Medartis and Medartis Footprint. The number of plates recorded as Soong grade 0+1 was determined for each design, then compared using the Marascuilo procedure. The Zimmer Biomet and Newclip plates were proximal to the Watershed line significantly more often than those by Synthes and Medartis Footprint. Plate position with the Medartis design was significantly more proximal to the Watershed line compared to its companion design, the Medartis Footprint plate. Plate design is a deciding factor when treating distal radial fractures, to avoid impingement when implant removal is not routinely planned.
Sepsis is organ dysfunction secondary to an inappropriate host response to infection. In the most severe cases, circulatory failure necessitating the introduction of vasopressor therapy is called septic shock. Sepsis and septic shock are life-threatening systemic organ dysfunctions requiring hospitalization in a critical care unit. According to several studies, sepsis accounts for around 30% of patients in these units. In this patient population, mortality in the critical care unit or in hospital is 25.8% and 35.3% respectively. Among the organ dysfunctions associated with sepsis, striated skeletal muscle damage is frequent and possibly severe. The literature refers to this as sepsis-induced myopathy, and describes three main mechanisms: mitochondrial dysfunction, exacerbated proteolysis and altered muscle membrane excitability. Of all the striated skeletal muscles that can be affected, the diaphragm and the muscles of the thoracic and abdominal wall play a major role in breathing. The diaphragm remains the main muscle involved in breathing. Its physiology is twofold. Firstly, through its contraction, the diaphragm is responsible for the lateral movement of the lower ribs, thus increasing the transverse diameter of the thorax. This first action is commonly referred to as "insertional". At the same time, lowering the phrenic center of the diaphragm increases abdominal pressure. Its distinctive upwardly convex domed appearance means that it is intimately in contact with both the chest wall and the abdominal cavity. This particular area of contact is called the apposition zone. It is on this zone, under the action of the abdominal compartment, that positive pressure also generates an outward thrust from the medial face of the lower ribs, a second action commonly referred to as "appositional". A number of studies, including that carried out by our team (US_DIAMONDS, NCT 02474797), have identified a high prevalence of diaphragmatic damage in patients with sepsis or septic shock. This can be as high as 60%. This diaphragmatic dysfunction would then be associated with a higher mortality rate in hospital and at D90 of discharge. The clinical evolution of post-resuscitation patients remains a little-studied subject. However, patients may present muscle dysfunctions in the longer term after a stay in intensive care. In our study, we demonstrated that less than half of patients recovered from diaphragmatic dysfunction on discharge from the critical care unit. In addition, Borges RC et al. found a significant decrease in the cross-sectional area of the rectus femoris at discharge, compared with the same measurement taken at D+2 of admission to the critical care unit. Finally, the impact of muscle dysfunction on dyspnoea during sepsis and after its resolution is uncertain. Similarly, the impact of muscle dysfunction and dyspnoea on quality of life is unknown. Sepsis is associated with muscle dysfunction of multiple mechanisms. The aim of this study is to assess the immediate and longer-term impact of muscle dysfunction on muscle, dyspnea and quality of life in patients with abdominal sepsis ("Abdominal sepsis" group) and patients with extra-abdominal sepsis ("Extra-abdominal" group). Depending on the location of sepsis, this study will enable us to assess and potentially confirm the preferential effect of abdominal sepsis on diaphragm function.
