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 general objective of PolyAGE is to explore the life experience of familial caregivers of aging persons with polyhandicap (>= 35 years). The investigators will question parents (objective 1) and siblings (objective 2) about the experiences, the social representations, the needs and the expectations, as well as the mechanisms associated with their choices about their children with polyhandicap. The objective 3 is to co-analyze parents' and siblings' experiences regarding the aging of their relatives with polyhandicap.
Post-Traumatic Stress Disorder is a psychiatric disorder that occurs after a traumatic event and is estimated to affect 5 to 12% of the general population. Around 70% of patients suffering from this disorder report sleep disorders (sleep apnea, insomnia, recurring nightmares, etc.). There are specific sleep disorders called Rapid Eye Movement (REM) sleep behavior disorders which correspond to nocturnal restlessness with sometimes violent behavior, often associated with intense dreams during a phase of sleep called REM sleep. These disorders are more frequently found in patients suffering from post-traumatic stress, such as veterans. However, the physiopathological link between these two disorders is poorly understood and studies on this subject are few in number. Through this study, the investigators wish to demonstrate whether there is a correlation between the severity of Post-Traumatic Stress Disorder and that of Rapid Eye Movement sleep behavior disorder. The main objective is to study the relationship between the severity of Post Traumatic Stress Disorder (PTSD) and the Rapid Eye Movement (REM) Sleep Behavior Disorder. This is an observational prospective study based on 4 questionnaires relating to the sleep (PSQI), the severity of the Rapid Eye Movement (REM) Sleep Behavior Disorder (REM RBDSQ, IRBD-SSS) and the severity of the Post-Traumatic Stress Disorder (PCL-5).
This research aims to understand the impact of fertility preservation consultation on transgender patients' projection and how the possibility of preserving gametes influences transgender people's transition paths, parenthood projects and health and health of transgender people through qualitative interviews. This research will also study the representations of members of medical and reproductive biology teams the possible use of stored gametes, and how these representations influence their clinical practice. clinical practice. To answer the research question, we plan to include 30 patients who have consulted for fertility preservation at the at the CECOS of the Tenon hospital, located in the 20th arrondissement of Paris, and 20 members of the center's healthcare team. care team.
Sickle cell disease (SCD) is characterized by recurrent vaso-occlusive pain crisis (VOC), which may evolve to acute chest syndrome (ACS), the most common cause of death among adult patients with SCD. Currently, there is no etiologic treatment to abort ACS. Therefore, management of ACS mostly involve a symptomatic approach including in routine, and as per recommendations, hydration, analgesics, supplemental oxygen, and transfusion. The polymerisation of sickle haemoglobin (HbS) is one major feature in the pathogenesis of vaso-occlusion. Current guidelines recommend red blood cell exchange transfusion (REX) in patients with severe ACS in order to improve oxygenation and reduce HbS concentration to blunt sickling. REX is often preferred over simple transfusion in this setting because it rapidly reduces HbS without raising final haematocrit. There are currently two methods for REX: manual (with sequential phlebotomies and transfusions) or automated (erythrocytapheresis). The former allows a sober use of red blood cell packs, while the latter achieves haematological targets (HbS and haematocrit) quickly and more consistently, but requires a special equipment and trained staff. As a result of inflammation and intravascular hemolysis, the plasma of patients with ACS may also contain several components that promote vaso-occlusion, lung injury and organ failure, including cytokines (e.g., IL-6), free haemoglobin and free haem. Conversely, it is depleted in haptoglobin and hemopexin, which normally bind to and clear cell-free haemoglobin. The addition of therapeutic plasma exchange to erythrocytapheresis during automated REX may therefore have a dual beneficial effect in patients with overt intravascular hemolysis: i) deplete the inflammatory mediators and products of hemolysis; ii) replete haptoglobin and hemopexin. REX modalities (automated vs manual) have not been tested during ACS. The hypothesis is that early-goal directed automated REX may accelerate the resolution of severe ACS as compared to manual REX.
Data on the optimal period for RRT weaning in critically ill patient are scarce. The current practice for RRT weaning is based on urine output, the threshold of which is debatable. Two recent observational studies have shown that an increase in urinary creatinine or urea concentrations is a better predictive marker of RRT weaning than urine output. An unjustified delay in RRT weaning leads to numerous complications such as catheter-related infections, delay of the patient's functional recovery, severe ionic disorder, bleeding, and induced hemodynamic instability. It also induces an increase workload for careers and in cost without any additional benefit for the patient. Conversely, too early weaning inevitably limits the prevention on fluid accumulation that is independently associated with an increased risk of mortality and inevitably leads to resumption of RRT requiring reinsertion of dialysis catheter resulting in potential complications. A multicentre randomized controlled trial will be then necessary and only able to identify the optimal RRT weaning strategy. The main objective is to compare two RRT weaning strategies on RRT duration in critically ill patients with acute kidney injury: a strategy based on combined criteria (urine output + urinary parameters) as compared to a single strategy based only on urine output. The study protocol will be an open-label, two parallel group, multicenter, randomized, controlled clinical trial, in which enrolled ICU adult patients will have RRT weaning based either on urine output alone (single strategy) or on urine output and urinary parameters (combined strategy). When the urine output is greater than 500ml/24h, the enrollment must be performed within 24hours in 2 groups:. " Single strategy ": In the single strategy, RRT weaning will be achieved when urine output exceeds 500ml/24h without diuretics or 2000ml/24h with diuretics use. " Combined strategy": In the combined strategy, when urine output exceeds 500ml/day with or without diuretic use, RRT will be stopped during 48h to assess urinary indices (urinary creatinine and urea). Soon as urinary indices are higher than thresholds values (urinary creatinine > 5.2mmol/day and urinary urea > 1.35mmol/kg/day, RRT will be weaned. If they are lower, a RRT session will be perform after which the weaning process will be resume. The primary endpoint is the number of RRT-free days at D30 with at least 7 consecutive days alive and without RRT.
Spatial navigation is a high-level cognitive function that enables humans to orientate themselves and move around in space by constructing a mental representation of the environment. It is particularly interesting because it involves numerous neural networks, linked to proprioception and vision, for example. Despite the versatility of this cognitive function, spatial navigation is little studied clinically, although changes in spatial planning and navigation strategies have been associated with many brain disorders, including Alzheimer's disease (Coughlan et al., 2018). This may be explained in view of the neuropsychological tests currently in use, which do not effectively assess spatial navigation disorders. In addition, many non-pathological parameters - in particular socio-demographic and lifestyle - (Wolbers & Hegarty, 2010; Coutrot et al., 2018) affect spatial navigation performance. Separating the pathological component from these non-pathological factors in spatial navigation can be challenging. In this context, Sea Hero Quest (SHQ) has been developed (Coutrot et al., 2018; Spiers et al., 2021) as an international-scale cognitive spatial navigation task that holds great promise for assessing spatial navigation performance during normal and pathological ageing. SHQ is a video game that implements classic tasks from the spatial cognition literature, and has enabled the trajectories of 4 million players with varied socio-demographic profiles to be collected. In addition to the direct measurement of spatial displacements, eye movements, measured by eye-tracking, provide additional information on the cognitive processes associated with visual attention. The analysis of eye movements can provide valuable information about the strategies employed by humans during spatial navigation (Zhu et al., eLife 2023). While it is well known that normal ageing and pathological ageing (e.g. in the context of Alzheimer's disease) affect performance in simple spatial navigation or visual attention tasks, the neurocognitive mechanisms involved in this deterioration remain poorly understood. The investigators hypothesise that the joint analysis of ocular and spatial traces will provide a more detailed understanding of the cognitive strategies deployed during a spatial navigation task, and therefore of these underlying mechanisms. The investigators therefore propose to jointly study the association between two complementary cognitive functions: spatial navigation and visual attention, and their relationship with normal and pathological ageing (confirmed Alzheimer's disease, plasma biomarkers and genetic risk factors for Alzheimer's disease). The joint analysis of these different signals has never been carried out as part of research into normal ageing and Alzheimer's disease.
Non-invasive ventilation is a mechanical ventilation who provides ventilatory support through a facemask, and without the need for tracheal intubation. In the emergency department, non-invasive ventilation is commonly used for the management of acute respiratory failure related with acute exacerbation of chronic obstructive pulmonary disease or with cardiogenic pulmonary oedema. Non-invasive ventilation is associated with an improvement in the outcomes, such as a decreasing in the intubation rate and in the mortality rate. Non-invasive ventilation failure is defined by a requirement to tracheal intubation in a patient managed by non-invasive ventilation. In the intensive care unit, non-invasive ventilation failure is reported from 15 to 50% of patients according to the ARF aetiologies. Due to delayed intubation, non-invasive ventilation failure is associated with poor outcomes and an increasing in the mortality rate. Due to the emergency department's patients (older and/or not to be intubate patients) the actual definition of non-invasive ventilation failure could not be applied as non-invasive ventilation may have been stopped not because it was unsuccessful but because it was unsuccessful in a patient with a do not intubate decision. Consequently, the prevalence of the absence of non-invasive ventilation success in the emergency department is unclear, and its predictive factor are unknown. The aim is to measure the prevalence of the absence of non-invasive ventilation success in the emergency department. The secondary objective is to measure the association between an absence of non-invasive ventilation success and outcomes and to identify risk factor of an absence of non-invasive ventilation success in the emergency department. It's a prospective observationnal multicenter study in department of Initiative Recherche Urgences Study Groups from January 2024, 15th to January 2024, 20th. The Initiative Recherche Urgences is a research network set up on the initiative of the Société Française de Médecine d'Urgence, with the aim of promoting and coordinating multicentre research projects in the field of emergency medicine, during short inclusion periods. The primary outcome is the proportion of patients who do not have an early success of non-invasive ventilation. The investigators measure the absence of success instead of failure because failure is defined by intubation and most of patients managed with non-invasive ventilation in an emergency department will not be intubated because of their age. The absence of success is defined by at least one of the following criteria measured at 1-hour: death, cardiorespiratory arrest, tracheal intubation, respiratory rate over 30 breaths/min, neurological impairment defined by a Glasgow coma scale < 14, signs of increased work of breathing, haemodynamic failure (defined by mean arterial pressure < 65 mmHg despite volumetric expansion and/or catecholamines), early stop of non-invasive ventilation due to intolerance. The investigators choose to measure at one hour because non-invasive ventilation is provided from one to two hours in the emergency department.
The improved survival of patients with acute respiratory distress syndrome (ARDS) over the last decades is related to the use of so-called "protective" mechanical ventilation. Two therapies have been shown to increase survival among the most hypoxemic patients (PaO2/FiO2 < 150 mmHg): a continuous use of neuromuscular blocking agents (NMBAs) for 48 hours in the acute phase of ARDS and prone positioning (PP). NMBAs and PP are part of the latest guidelines from French ICU Society. However, North American guidelines recommend PP for patients with severe ARDS only but not NMBAs, given the results of the ROSE study which did not confirm the benefit on mortality demonstrated in the ACURASYS study. However, in the ROSE study, ventilatory strategy, use of NMBAs and PP were different from the ACURASYS study. Yet, NMBAs and PP are frequently associated in clinical practice, particularly with the COVID-19 pandemic, but also in randomized trials. In the PROSEVA study, almost all the patients (91%) received a continuous infusion of NMBAs during PP. Indeed, there is a common physiopathological rationale in both techniques: they favor the homogenization of transpulmonary pressures (TPP), reduce lung overdistension, Pendelluft effect and thus ventilator induced lung injury (VILI), in particular barotrauma and biotrauma. This reduction of biotrauma has been demonstrated for PP and NMBAs separately, but never by comparing the combined effect of the 2 techniques to each of them separately. This comparison requires reliable tools. In recent years, the "soluble form of the receptor for advanced glycation end products" (sRAGE), a new biomarker specific of pulmonary epithelial aggression and therefore of biotrauma, has been described and evaluated during ARDS and appears to be associated with the severity of pulmonary damage and prognosis. Overall, despite an interesting physiopathological rationale and a clinically widespread practice, there is currently no study evaluating the synergistic effect of PP and NMBAs in the treatment of ARDS, in particular on the prevention of VILI, and more precisely of biotrauma. This question seems crucial to better specify the respective place of each of these treatments in the management strategy of ARDS patients whose prevalence and mortality remain high. The objective of this study is therefore to evaluate, using a recent and reliable biomarker, the synergistic effect of a short-term NMBAs infusion using cisatracurium and PP on the reduction of biotrauma during moderate to severe ARDS. The investigators will compare this "synergistic" treatment to the use of PP alone. They will also evaluate, in secondary objectives, the effects of PP and NMBAs combination on clinical outcomes and on the patients' prognosis.
The aim of the current study is to evaluate the efficacy of transperineal focal microwave ablation (TMA) of the prostate transition zone as a new treatment for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) within a prospective single-institutional pilot study.
A sub-nasal mask with a skirt that fits the nostrils and with a dedicated port for the nasogastric tube has recently been introduced. This interface has never been compared to nasal-oral masks. We hypothesise that such a sub-nasal mask increases comfort compared to a conventional naso-oral mask. The primary objective is to compare the comfort of the sub-nasal mask with that of a standard naso-oral mask.
