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 aim of the research is to analyze whether 18F-FDG PET helps in the diagnosis and therefore in the management of the patient.
Systemic SClerosis (SSC) is a systemic disease characterized by limited or diffuse cutaneous sclerosis, microangiopathy, overproduction of autoantibodies and variable organ damage due to vasculopathy and/or fibrosis. The loss of self-tolerance is believed to be caused by the dysregulation of both innate and adaptive immune systems and may involve Reactive Oxygen Species (ROS). Neutrophils are potent producers of ROS and may play a role in endothelial cells and fibrobasts dysfunction, as in autoantibodies generation. However, their role in SSC pathogenesis remains to be determined. Recent studies discovered abnormal regulation of Neutrophil Extracellular Traps (NETs) in other auto-immune diseases such as Systemic Lupus Erythematosus (SLE). NETs are web-like structures composed of chromatin backbones and granular molecules. They are released by activated neutrophils through a process called "NETosis". Nets were first described in 2004 as a novel host defense mechanism to trap and kill foreign pathogens. Recent evidence shows that NETs also participate in the pathogenesis of a variety of inflammatory and autoimmune diseases, including SLE. The investigators recently highlighted this phenomenon in SSc, especially in patients with vascular complications and/or at a early stage of the disease. The investigators will now explore the factors implicated in this dysregulation of NETosis in SSc.

Obstructive sleep apnea syndrome (OSAS) is associated with hyperaldosteronism with elevated plasma aldosterone/renin ratio, the physiopathological mechanism of which remains uncertain. This hyperaldosteronism contributes to the development of arterial hypertension and cardiovascular complications observed in patients with OSA, in particular by increasing arterial stiffness and heart rate variability. The frequent association of OSA with obesity with metabolic syndrome suggests that excess weight could be responsible for stimulation of aldosterone secretion independent of the renin/angiotensin system. Several studies indicate in particular that the production of mineralocorticoids by the adrenals could be activated by various adipocyte secretion products such as leptin and certain fatty acids after oxidation in the liver. In addition, a recent study showed that basal aldosterone secretion is also controlled by substance P released within the adrenal tissue itself by nerve fibers belonging to the splanchnic contingent. Thus, the oral administration of aprepitant, an antagonist of the substance P receptor (NK1 receptor), to healthy volunteers induces a reduction of approximately 30% in the overall secretion of aldosterone assessed by measuring aldosteronemia and 24-hour aldosteronuria. To the extent that OSA causes sympathetic hypertonia, the hypothesis is that the associated hyperaldosteronism could result from activation of the nervous control of aldosterone secretion, involving substance P and the NK1 receptor. If this is indeed the case, the administration of aprepitant to patients with OSA should result in a significant reduction in aldosteronemia.
This is a monocentric, prospective, before-and-after, open-label controlled study, two groups of 99 patients each: "control" group - usual care - versus "intervention" group "Intervention" group - patient information via an explanatory video followed by a 15-minute music therapy session of the patient's choice in the operating waiting room.
Catastrophizing is a negative evaluation of events. What surgery concerns, pain catastrophizing is one of the main risks of postoperative pain and / or poor functional recovery. The best survey to evaluate pain catastrophizing is the PCS (Pain Catastrophizing Scale). According to the authors, catastrophizers report more negative pain related thoughts, more emotional distress and more pain than non-catastrophizers. The PCS is a significant predictor of pain intensity and so of poor functional recovery. It is already well known that anxiety and catastrophizing predict postoperative pain. The actual studies focus mainly on functional recovery of knee and hip arthroplasties, but less on pain and functional recovery of hallux valgus surgery. According to several authors, adapted psychological support of preoperative catastrophizing could allow a better postoperative evolution. Our hypothesis is that a preoperative psychological consultation of catastrophizing patients is efficient to lower pain catastrophizing in adult patients undergoing a surgical operation for hallux valgus. The first objective is to evaluate the impact of a psychological support of preoperative pain catastrophizing during a hallux valgus surgery.The principal evaluation scale is the pain catastrophizing score before and after surgery. The second objective is to evaluate the pain and functional recovery of pain catastrophizing patients. The criteria of this survey are: anxiety score (usual and actual), pain and function according to the FAOS (Foot and Ankle Outcome Score) pain (Analogic Visual Scale).
"Physical activity is recognized as beneficial for patients living with type 1 diabetes (T1DM), with a demonstrated effect not only on HbA1c control [1] but also on reducing the incidence of diabetes-related complications [2,3]. It is recommended that patients living with T1DM perform 150 minutes of accumulated physical activity per week, without exceeding two consecutive days without physical activity [4]. Indeed, one meta-analysis reported that moderately vigorous activity (≥4.5 METs) was beneficial compared with lower-intensity activity, while three other studies noted that only vigorous physical activity (≥6 METs) predicted lower all-cause mortality rates [5]. However, T1DM can represent a major obstacle to physical activity because of the occurrence of fairly frequent hypoglycemia, including after physical effort, the need for early resugaring but also the risk of hyperglycemia (rebound or with certain activities) [6]. The advent of automated insulin delivery systems has led to a significant improvement in time on target and a reduction in the frequency of hypoglycemia, including during physical activity in some studies [7-9]. The aim of this study is therefore to evaluate, in a cohort of patients with T1DM, whether the implementation of a closed-loop automated insulin delivery system increases physical activity in patients with T1DM. Based on the interpretation of the ONAPS-PAQ [10], the investigator hypothesize that the implementation of the closed-loop system enables an individual to reach the 3000 MET/min/week threshold (considered ""Active+"" from this threshold onwards).
Introduction : The birth of a child is usually a happy event that caregivers working in delivery rooms share with families. Unfortunately, newborns sometimes need palliative care as soon as birth occurs. In France, neonates who were liveborn under 24+0 weeks amenorrhea (date of last mentrual period) or weighing less than 500 grams) usually have non resuscitation in delivery room [Ancel 2020]. Some of them are considered as viable (referring to World Health Organisation definition : either term ≥ 22 + 0 amenorrhea week or birth weight ≥ 500 grams), others as nonviable (term < 22 AW and birth weight ≤500 grams). In France, legislative development over last two decades have allowed the emergence of palliative care in delivery room. In a French survey in 2016, 83% of maternities were confronted at least once a year with this situation.
DIABAGE (Diabetes Advanced Glycation End products) study was conducted between 2015 and 2017. It included 196 type 1 diabetic patients with more than 10 years of diabetes. It revealed a significant association between the occurrence of vascular complications and tissular Advanced Glycation End products (AGEs) as well as with some circulating AGEs. This protocol is a continuation of that initial research.
The association of anthracyclines (ANT) and paclitaxel (Tax) is one of the main treatments used in breast cancer. These treatments are known to induce severe side effects such as a decrease in overall exercise capacity (physical condition) in response to muscle and cardiorespiratory alterations. If exercise may be an effective preventive strategy, it seems important to prescribe the most efficient exercise modality. Among them, concentric cycling (i.e., classic cycling) can significantly induce metabolic stimulus, which is needed for maintaining exercise capacity. The PROTECT-07 study aims to demonstrate the superiority of a training program based on concentric cycling during chemotherapy compared to standard treatment. The duration of the training program is 15 weeks with one session per week.
