NCT ID: NCT05565144 Completed - Stroke Clinical Trials

Brain Hemorrhage and Functional Outcome in Stroke Patients With CAA Features on Pre-thrombolysis MRI Treated With Intravenous Thrombolysis (Thrombolysis in CAA) ( Thromb in CAA )

Thromb in CAA
Start date: October 2, 2022
Phase:
Study type: Observational

Background: In stroke patients treated with intravenous thrombolysis (IVT), presence and high number of strictly lobar cerebral microbleeds (compatible with cerebral amyloid angiopathy, CAA) seems to be associated with increased risk of hemorrhagic transformation, symptomatic hemorrhagic transformation, remote hemorrhage, and poor functional outcome. Some of these reported CAA patients with cerebral microbleeds also had chronic lobar intracerebral haemorrhage. Few data is available on IVT-treated CAA patients showing cortical superficial siderosis. There are no reports studying factors associated with brain hemorrhagic complication or functional outcome inside a group of IVT-treated CAA patients. Our aim was to evaluate brain hemorrhagic complications on 24h-CT and functional outcome after IVT in stroke patients with CAA features on pre-IVT MRI. Methods: In our stroke center, IVT decision in patients with CAA MRI features is left at the discretion of the treating physician. We retrospectively screened pre-IVT imaging of 959 consecutive IVT-treated stroke patients (between January 2015 and July 2022) without ongoing anticoagulation therapy for probable CAA MRI features defined by modified Boston criteria. After exclusion of 119 patients with lacking MRI (n=47), with MRI showing motion artefacts (n=49) or with alternative chronic brain hemorrhage cause on MRI (n=23), 15 IVT-treated patients with probable CAA on pre-IVT MRI were identified. In these 15 patients, clinical, biological and MRI characteristics were compared between patients with vs. without post-IVT hemorrhage and between patients with poor (MRS 3-6) vs. good (MRS 0-2) functional outcome at discharge.

NCT ID: NCT05565131 Completed - Pedicle Screw Clinical Trials

Performance Measurement and Safety Evaluation of the PYTHEAS® ODYSSEE Angular Assistance System for Intra-pedicular Screw Placement in Adult Spine Surgery

ODYSSEE
Start date: September 23, 2022
Phase: N/A
Study type: Interventional

Pedicle screw malposition is a common problem for spine surgeons. A poorly placed screw can lead to potentially serious complications (hemorrhage, paralysis) in the short- or medium-term. Accurate images during surgery facilitates preoperative planning and aids the placement of pedicle screws. Surgical navigation covers all techniques and equipment (hardware and software) needed to perform a computer-assisted procedure with 3D image visualization of the surgical act. Surgical navigation systems have been on the market for about 15 years. Surgical navigation increases the accuracy of pedicle screw placement. Many technologies are available, but they are expensive and often require extensive instrumentation. The PYTHEAS® ODYSSEE angular assistance system has many advantages over more widely used systems. Indeed, this system provides surgeons with the necessary information to correctly insert pedicle screws during posterior spondylodesis procedures for the treatment of deformity, osteoarthritis (degenerative spine) and trauma. Compared to competing solutions, the purpose of this device is to reduce pedicle screw malpositioning while offering minimal radiation exposure and the least possible impact on the conventional surgical workflow. It is a lightweight, efficient and easy-to-use medical device with 2-step functionality: 1) Surgical planning of pedicle screws based on a preoperative scan; 2) Angular assistance tool during surgery. The study investigators wish to evaluate the performance and safety of the PYTHEAS® ODYSSEE medical device (not CE marked) as well as its usability in a pilot study of first use in humans. Without a navigation system, the literature reports that on average 9 to 10% of perforations are incorrectly positioned by the "free hand" method. With the PYTHEAS® ODYSSEE angular assistance device, the study hypothesis is that this rate will be 5%, i.e. a 50% improvement.

NCT ID: NCT05564546 Completed - Clinical trials for Obstructive Ventilatory Disorders

Study of Chronic Exposure of the Population Living on the Atlantic Coast and on the Caribbean Coast, in Martinique, During the Stranding Period and Outside the Stranding Period of Sargassum Seaweeds

SÉSAR
Start date: August 18, 2022
Phase: N/A
Study type: Interventional

Sargassum are pelagic brown sea algae. Two species grow on the surface of the ocean and drift freely with ocean currents in the form of slicks: the pelagic Sargassum fluitans and Sargassum natans. Since 2011, massive strandings of Sargassum seaweed in the French West Indies are to be deplored. In recent years, strandings have increased. In Martinique, sargassum stranding occurs mainly on the Atlantic coast. The duration of stranding from one year to another is variable, but the period during which the stranding is maximum is between April and October. The accumulation of strandings causes the compaction of algae and limits access to oxygen, which leads to anaerobic degradation which quickly results in the release of various gases, in particular hydrogen sulphide (H2S). Acute H2S poisoning is well characterized clinically according to exposure (cutaneous, respiratory, ophthalmological, digestive, neurological symptoms, etc.). On the other hand, there are very few data available on the clinical effects of prolonged, repeated exposure and most often at low doses. Among the toxic effects for which there are still uncertainties regarding long-term exposure to H2S are lung function, measured by spirometry, and airway inflammation, appreciable by measurement of FeNO (fractional exhaled nitric oxide). The investigators consider it relevant to focus on the clinical and biological characteristics of the population exposed to sargassum in Martinique, in the field, assuming that exposure to sargassum H2S causes pulmonary effects measurable by spirometry and by FeNO, during the stranding period and outside this period.

NCT ID: NCT05564507 Completed - Clinical trials for Cardiovascular Diseases

Effectiveness of Simulation-based Training on Transoesophageal Echocardiography Learning

SIMULATOR
Start date: November 1, 2020
Phase: N/A
Study type: Interventional

Background: Simulation-based training in transesophageal echocardiography (TEE) seems promising. However, data are limited to non-randomized or single-center studies. Objectives: This large multicenter randomized, parallel-group, unblinded, study will assess the impact of simulation-based versus traditional teaching on TEE knowledge and performance for medical fellows in cardiology. Eligibility: - All consecutive fellows in cardiology of all training levels (year 1-4) - who have never performed a TEE alone Design: - Multicenter, parallel-group, unblinded, randomized study with a prospective enrollment of all consecutive fellows in cardiology of all training level (year 1 to 4) who were recruited in 42 centers throughout France. - Randomization with stratification by center will be performed at the individual (fellow) level in 1:1 ratio to assign all the fellows to the traditional group or to the TEE simulation-based training group. - Each participant will complete two different tests during the study: 1) a pre-training test before starting the educational program; and 2) a final test performed 3 months after the end of the educational program. Each of these tests will include a theoretical test and a practical test on a TEE simulator. - The coprimary outcomes of the study to compare the two groups will be the scores in the final theoretical and practical tests after the training will be completed.

NCT ID: NCT05564208 Completed - Clinical trials for Healthy Participants

A Study to Evaluate the Effect of Food on the Level of Circulating Elafibranor in Healthy Participants After Intake of a Single Tablet

Start date: October 27, 2022
Phase: Phase 1
Study type: Interventional

This study will evaluate the effects of food on how much test drug is able to access the circulation and reach the target area (known as bioavailability). The test drug, elafibranor (IPN60190), is in development for the treatment of primary biliary cholangitis (PBC). PBC is a rare, long-term autoimmune disease of the liver. An autoimmune disease occurs when the immune (defence) system treats healthy parts of the body as if they were foreign and attacks them. This study will be in healthy volunteers, so this trial is not to test if the drug helps to improve health.

NCT ID: NCT05562141 Completed - Analgesia Clinical Trials

Oxidative Stress in the Patient With Peroperative Analgesia by Intravenous Lidocaine

OSPAIL
Start date: November 22, 2022
Phase:
Study type: Observational

Depending on the anesthesiologist's habits, injection or not of a 1.5 mg/kg bolus of lidocaine at induction of anesthesia followed by a continuous infusion of 1.5 mg/kg/h. Additional blood sample at 3 different times without additional puncture compared to usual management: 1) during the placement of the venous line before induction (Reactive Oxygen Species), 2) 1h after the end of induction at the time of blood gas to adapt ventilation (Reactive Oxygen Species), 3) at 24h of the beginning of the intervention (Reactive Oxygen Species and antioxidant molecular profile).

NCT ID: NCT05561283 Completed - Quality of Life Clinical Trials

Evaluation of the Satisfaction and Relevance of Leadership Training for Residents

START
Start date: November 14, 2022
Phase: N/A
Study type: Interventional

Health students are the future actors of the health system. They are exposed to many stressors in their journey. The quality of life of medical students is alarming worldwide: 11.1% of undergraduate and postgraduate residents reportedly have suicidal ideation and 27.2% have depressive symptoms. In addition, 44.2% suffer from burn-out syndrome. In the third cycle, 28.8% suffer from depressive symptoms and 35.1% from burn-out syndrome. This finding is shared internationally among medical residents. Health professionals are facing a global problem which it is crucial to act. At national level, a survey on the mental health of young doctors carried out in 2017 found, among the 7603 residents who responded a prevalence: 22.8% of depressive symptoms, 59.7% of anxiety symptoms, 23.4% of suicidal thoughts, including 5.0% in the month prior to the survey. In 2018, a French report on the quality of life of health by Dr Donata Marra highlighted a real malaise affecting residents and the need to intervene "for residents, for carers and for patients", through the implementation of specific recommendations. The proposal 6 of the report emphasises the prevention of psychosocial risks through educational interventions such as training in collaborative management. On a personal level, the aim is to the leadership of each individual, in terms of stress management, communication, cross-disciplinary skills or even the introduction of relational simulations in the teaching of an awareness of deviant behaviour and harassment. The stress factors are indeed multiple during health studies confrontation with death, competition, increasing responsibilities… Perceived stress has a negative impact on the quality of life and burnout. Effective stress management strategies could therefore help to improve the quality of life of residents. In this context, the analysis of the literature highlights three main areas of intervention that could contribute to resident leadership in favour of their quality of life: stress management, healthy living and the construction of a professional identity. The Junior Leadership programme for residents from the beginning of their professional formation designed to provide basic knowledge and skills in healthcare leadership and to develop cross-disciplinary skills. The aim is to provide the necessary support for the success of the resident's professional project by participating in the improvement of their quality of life and the prevention of psycho-social risks. The study therefore propose to evaluate the feasibility of training in leadership and meditation on the satisfaction of resident.

NCT ID: NCT05561166 Completed - Epilepsy Clinical Trials

EPIDREAM 1 : Study of Dreaming in Epilepsy

EPIDREAM 1
Start date: February 7, 2023
Phase:
Study type: Observational

Dreaming is a sleep-associated cognitive process whose neural substrates and functions remain poorly understood. In healthy subjects, the frequency of dream recall is influenced by several factors such as age, gender, interest in dreams and sleep quality. The content of dreams mainly depends on waking life experiences, especially when they are recent and have a strong emotional content. The function of dreams remains debated but it is widely accepted that dreams play a role in emotional regulation. Modifications in dreams are observed in several neurological diseases and sleep disorders, due to the modifications of sleep related to these diseases, as well as to associated disturbances in cognitive functioning and to the impact on such diseases on waking life. Epilepsy is a neurological condition characterized by a predisposition to seizures resulting from excessive and synchronized abnormal brain activity; it is associated with numerous co-morbidities including sleep and cognitive disorders, which are present in nearly one in two patients. However, the influence of epilepsy on sleep-related cognitive processes is poorly understood. It is suspected that nocturnal epileptic activity disturbs sleep-related memory consolidation processes, but the consequences of epilepsy on dreams have been little investigated. The study of the determinants (epilepsy syndrome, location of the epileptic focus, presence of sleep-related seizures, certain anti-epileptic treatments, alteration of the quality of sleep) of dream characteristics in this context could lead to a better understanding of the dreams physiology, the interactions between epilepsy and sleep, as well as the cognitive and emotional functioning related to sleep in epilepsy. It could also determine whether dream characteristics can provide information on the epilepsy syndrome and on the presence of nocturnal seizures, and thus constitute a diagnostic tool. In this cross-sectional observational study, we aim to identify determinants of dream recall in relation to epilepsy by administering a simple and brief questionnaire on sleep and dreams, to all consecutive patients seen in epileptology consultation during 12 months. Our objectives are 1. To determine whether the presence of sleep-related seizures influences the frequency of dream recall in patients with epilepsy 2. To describe the characteristics of dreams in epilepsy, the influence of epilepsy on dreams and to characterize the determinants of dream recall frequency in patients with epilepsy We hypothesize that the presence of seizures during sleep will be associated with poorer sleep quality, increased frequency of dream recall, and that we will observe the inclusion of epilepsy symptoms in dream content, particularly in subjects who are aware of their nocturnal seizures and are awakened by them.

NCT ID: NCT05557149 Completed - Clinical trials for Cocaine Use Disorder

Virtual Reality Exposure and Respiratory Relaxation-Based Coping With Cocaine Craving in Cocaine Users

RVCOC
Start date: March 31, 2021
Phase: N/A
Study type: Interventional

Our study main objective is to test whether virtual reality exposure could elicit cocaine craving and its physiological arousal in cocaine users. Investigators aim to compare self-reported cocaine craving, self-efficacy to cope with craving and emotional states levels in 11 voluntary and adults cocaine users in 3 consecutive 10-mins conditions: Neutral VR (virtual reality exposure to neutral stimuli), Cocaine VR (virtual reality exposure to cocaine use-related stimuli) and Relaxation (respiratory relaxation).

NCT ID: NCT05555914 Completed - Tetraplegia Clinical Trials

Neural Stimulation for Hand Grasp in People With Tetraplegia

AGILIS
Start date: October 10, 2022
Phase: N/A
Study type: Interventional

A selective neural stimulation as the investigators propose allows to stimulate several muscles via a single electrode. Neural stimulation requires less energy for muscle activation. In our approach, 2 electrodes will be implanted above the elbow on the median, the ulnar and the radial nerves. This considerably reduces the number of implanted elements and therefore i) the risk of infection, ii) the risk of failure, iii) the surgical risk through minimally invasive surgery. Our main hypothesis is that multipolar neural electrical stimulation of the median and the ulnar nerve (flexion) and the radial nerve (extension) allows: - on the one hand, a selective, individualized motor activation (muscle by muscle) - on the other hand, a synergistic motor activation (association of several muscles) for the purpose of production of functional movements.
