NCT ID: NCT06051773 Not yet recruiting - Systemic Sclerosis Clinical Trials

Evaluation of Muscle Involvement in Systemic Sclerosis

MUSSc
Start date: January 1, 2024
Phase:
Study type: Observational

Muscle involvement is poorly described in patients with systemic sclerosis (SSc) . The prevalence of muscle damage is evaluated at 5-95 % of SSc patients, particularly due to variable definitions depending on the series in the scientific litterature. Muscle clinicobiological and histological presentation an response to immunosuppressive treatments are highly variable. Muscle involvement defined by creatinine kinase (CK) elevation, the presence of electromyography (EMG) abnormalities and/or muscle magnetic resonance imaging (MRI) hyperintensities and/or muscle biopsy inflammation appears to be associated with diffuse SSc, the presence of cardiac damage, and anti-PM-Scl antibodies. The main objective is to describe muscular manifestations associated with SSc. Secondary objectives are: - to compare characteristics between SSc patients with and without muscle involvement - to determine homogeneous groups of SSc patients with muscle involvement

NCT ID: NCT06051682 Recruiting - Clinical trials for Artificial Intelligence

Optimization of the Diagnosis of Bone Fractures in Patients Treated in the Emergency Department by Using Artificial Intelligence for Reading Radiological Images in Comparison With Traditional Reading by the Emergency Doctor.

FracturIA
Start date: September 11, 2023
Phase: N/A
Study type: Interventional

As part of the management of a patient with suspected bone fractures, emergency physicians are required to make treatment decisions before obtaining the imaging reading report from the radiologist, who is generally not available only a few hours after the patient's admission, or even the following day. This situation of the emergency doctor, alone interpreting the radiological image, in a context of limited time due to the large flow of patients to be treated, leads to a significant risk of interpretation error. Unrecognized fractures represent one of the main causes of diagnostic errors in emergency departments. This comparative study consists of two cohorts of patients referred to the emergency department for suspected bone fracture. The first will be of interest to patients whose radiological images will be interpreted by the reading of the emergency doctor systematically doubled by the reading of the artificial intelligence. The other will interest a group of patients cared for by the simple reading of the emergency doctor. All of the images from both groups of patients will be re-read by the establishment's group of radiologists no later than 24 hours following the patient's treatment. A centralized review will be provided by two expert radiologists. Also, patients in both groups will be systematically recalled in the event of detection of an unknown fracture for hospitalization.

NCT ID: NCT06051214 Recruiting - Solid Carcinoma Clinical Trials

Thrombin Generation and Prediction of Thromboembolic Events in Oncology Patients at Risk

THROMBIN
Start date: September 12, 2023
Phase: N/A
Study type: Interventional

Coagulation is a complex system which, through the action of thrombin, leads to the formation of fibrin, which stabilises the platelet clot. Any disturbance in the balance between procoagulant and anticoagulant factors can tip the physiological process either towards a state of hypercoagulability leading to thrombosis or hypocoagulability responsible for bleeding. Due to a number of factors, cancer is associated with a state of hypercoagulability, leading to thrombosis. The incidence of venous thromboembolism (VTE) in cancer patients varies from 15 to 20% depending on the type of cancer, the stage of the disease and the associated treatments (ONCORIF data, November 2021). The risk of venous thromboembolism (VTE) is greatly increased in cancer patients (RR x 3 to 6) and doubled in the case of associated chemotherapy (1). VTE is a poor prognostic factor, occurs mainly in the first 6 months after diagnosis and is the second leading cause of death in cancer patients. At present, haemostasis tests performed in medical laboratories independently explore the different coagulation pathways but do not allow the overall haemostatic profile of a hyper- or hypocoagulable patient to be assess. Based on this knowledge base, the aim of our study will be to monitor thrombogram profiles during the management of patients with tumours at high risk of thromboembolism (lung, pancreas, stomach, glioblastoma) and to correlate these profiles with the risk of a thromboembolic event occurring in these patients. The aim of the project is to validate a simple predictive test (suitable for clinical use) for the risk of thromboembolism in these patients. These analyses will also make it possible to monitor the impact of chemotherapy on changes in the thrombin generation test in patients.

NCT ID: NCT06051006 Recruiting - Cochlear Implants Clinical Trials

The Value Electrical Stapedial Reflex Thresholds (eSRTs) Cochlear Implant Mapping

eSRT
Start date: December 7, 2023
Phase:
Study type: Observational

One of the most significant challenges in cochlear implant programming, particularly for very young children and those with an associated pathologies, is the measurement of subjective comfort levels (= C-Subjective). Currently, to define this C-Subjective level, patients are presented with a loudness scale and must indicate whether the sound stimulus, sent via the implant, is soft, comfortable, or loud. The lower and upper stimulation levels must be determined for each electrode in order to program the implant. For many patients this can be difficult due to a lack of auditory experience and confusion between the sensation of sound intensity (weak or loud) and frequency (low or high). A less commonly used but more objective approach to programming upper stimulation levels involves the use of the electrical stapedial reflex threshold (eSRTs) value. eSRTs are a promising measure, given the demonstrated correlation between the threshold that generates a stapedial reflex and the C-subjective level. Furthermore, eSRTs can be recorded in the majority of patients, and can typically be evoked at a comfortable stimulation level i.e. inferior to the uncomfortable level. The main objective of this study is investigate the link between subjective comfort levels (C-subjective levels) and the eSRT.

NCT ID: NCT06050993 Not yet recruiting - Liver Cirrhosis Clinical Trials

Effects of Platelet Mimicking Nanoparticles in Patients With Cirrhosis

HEMCITAP
Start date: October 15, 2023
Phase:
Study type: Observational

Haemostasis of cirrhotic patients is disturbed at different levels: primary haemostasis, coagulation and fibrinolysis, leading to a new haemostatic balance. Thrombocytopenia and thrombopathy are counterbalanced by elevation of Von Willebrand factor (VWF) and diminution of ADAMTS13 activity. Exploration of primary haemostasis is difficult in the laboratory, and non-interpretable in case of thrombocytopenia. Moreover, these tests are not performed under flow conditions. The T-TAS®01 system analyses the total haemostatic capacity in whole blood under shear stress, with chips coated with type 1 collagen. Platelets transfusion performs poorly in cirrhotic patients and is not recommended before invasive procedure. Platelets mimicking nanoparticles (PMNs) have been developed by Pr Sen Gupta (Case Western Reserve University, Cleveland, Ohio (OH), USA). PMNs have been proven to collaborate with platelets and enhance haemostasis in different shear conditions in vitro and in different models of haemorrhage in vivo. The assumption of this study is that the perfusions characteristics of cirrhotic patients in the T-TAS®01 system will be different from those of non-cirrhotic patients, and that platelets mimicking nanoparticles will improve these characteristics.

NCT ID: NCT06050902 Recruiting - Clinical trials for Central Venous Catheterization

Standard Ultrasound Guidance vs. New Needle-steering Device in Subclavian Venous Catheterization

NEEDLEVISIO2
Start date: January 16, 2024
Phase: N/A
Study type: Interventional

Up to two-thirds of intensive care unit patients require central venous catheterization for which ultrasound-guided placement is now recommended. In this context, the team performed a prospective randomized simulation trial on a mannequin ("reduced torso model"), to compare the standard ultrasound guidance technique with an ultrasound-guided technique assisted by a new needle-steering device. The preliminary results show a statistically significant improvement in subclavian venipuncture (shorter success time, fewer multiple skin punctures, fewer punctures of the posterior wall of the subclavian vein and needle redirection, greater comfort) and argue for a clinical trial to test the performance of this new device in situation with intensive care unit patients. The hypothesis is that the needle-steering device will result in a better success rate of subclavian venous cannulation, at first puncture, compared with the conventional ultrasound-guided technique.

NCT ID: NCT06050642 Recruiting - Clinical trials for Diabetes Mellitus, Type 1

Study of the Impact of PROximity Support for Patients With Type 1 DIABetes Treated With an Insulin Pump or Closed Loop.

PRO-DIAB-1
Start date: September 4, 2023
Phase: N/A
Study type: Interventional

Amidst medical innovations, many Type 1 diabetes patients using advanced therapy show improved control but still suffer from diabetes-related distress. To tackle this, the investigators propose an "enhanced care" model involving healthcare providers and pharmacists. The study compares standard and enhanced care for Type 1 adults, focusing on the pharmacist's role. The main question it aims to answer is : In patients with type 1 diabetes treated with pump or closed-loop therapy, does the improved enhanced care versus conventional layout improve diabetes-related distress at 12 months? Participants will complete a monthly online questionnaire to assess their diabetes-related distress as well as their frequency of use of standard and enhanced care as well as the associated patient satisfaction.

NCT ID: NCT06050369 Recruiting - OCD Clinical Trials

Objective Characterizatoion of Repetitive Behaviors

Start date: November 1, 2023
Phase: N/A
Study type: Interventional

Introduction: Repetitive behaviors (RB) constitute a broad range of symptoms across different psychiatric/neurologic disorders. The most famous are stereotypies (found in autism), compulsions (found in obsessive-compulsive-disorder, OCD) and tics (found in Gilles de la Tourette syndrome, GTS). For some patients, it is sometime difficult to distinguish the nature of the repetitive behaviors presented, however this distinction is crucial in order to chose the appropriate treatment. Aim: In our study, the investigators will try to define electrophysiological and accelerometric marker of both OCD and tics to allow objective distinction between both tics and compulsions. Method: Subjects: Both OCD and GTS patients will be recruited, 25 patients in each group. Protocol: our study protocol will involve two step: a step in laboratory, another step at patient home. - first step: both patients group will be recorded through a high density EEG and a portative EEG while doing a task of symptom provocation. Then they will get an anatomical MRI for source recontruction. Finally, the patients will have to mimic their symptom while wearing an accelerometer (a smartwatch). - second step: both patient groups will be recorded at home through a portative EEG while tagging their symptom through a smartwatch (also used for accelerometry). After the recording, the patients will keep the smartwatch for 2 weeks, still tagging their sympoms (compulsions or tics).

NCT ID: NCT06050304 Not yet recruiting - Clinical trials for Cocaine Use Disorder

CRACK-TARGET 1: ÉTUDE DESCRIPTIVE DE LA SENSIBILISATION COMPORTEMENTALE OBSERVÉE et ATTENTES

CRACK-TARGET
Start date: September 2023
Phase:
Study type: Observational

This research focuses on behavioral sensitization (BS) a specific behavioural disturbance in crack-cocaine addiction. The primary objective is to observe whether BS can be demonstrated in an ecological setting in crack dependent users by continuous actimetry for 3 weeks. It is planned to include 20 persons with a current crack-cocaine addiction with a preferential use of rapid administration route (intravenous or smoke), in a care institution: Fernand Widal Hospital. In the proposed research, the investigators will assess the movements of crack-cocaine dependent users in relation to consumption. They will have to wear continuously for 3 weeks an actimeter. They will also have 3 blood tests trying to identify biomarkers of BS.
