NCT ID: NCT05694806 Recruiting - Clinical trials for Mediastinal Diseases

Clinical Impact of Thoracic Scanographic Characteristics of Hematologic Malignancy Patients

Start date: June 1, 2022
Study type: Observational

The mediastinum can be the site of benign or malignant tumors, including 10 to 20% of hematological malignancies. Mediastinal mass syndrome (MMS) includes symptoms due to irritation, invasion or compression of the organs of the mediastinum. This syndrome includes respiratory manifestations that may be secondary to compression of the tracheobronchial tree, venous vascular manifestations with the superior vena cava syndrome or arterial manifestations, cardiac manifestations, digestive or nervous manifestations. The management of a mediastinal syndrome is a diagnostic and therapeutic emergency requiring the collaboration of several disciplines in order to achieve the most effective but least deleterious way possible to diagnostic imaging, etiological biopsy, and the possible implementation of life-saving symptomatic measures before the initiation of etiological treatment. Diagnostic thoracic imaging relies primarily on thoracic computed tomography (CT) to determine the size and nature of the mediastinal mass, the presence and extent of tracheobronchial or great vessel compression, the presence of pleural and/or pericardial effusion, pulmonary embolism, parenchymal lesions, and possibly subdiaphragmatic lesions. However, the potential severity of MMS is often under-diagnosed in adult patients, particularly in the context of hematologic malignancy. Indeed, we have very little literature on the initial management of these patients at risk. The present study propose to conduct the first multicenter study to analyze the characteristics (clinical, scanographic, echocardiographic, hematological and resuscitation) of the initial management of patients with symptomatic MMS at diagnosis or at relapse of a patient with MH admitted to the Intensive Care Unit (ICU).

NCT ID: NCT05693116 Recruiting - Clinical trials for Squamous Cell Carcinoma

Survival and Prognostic Factors of Squamous Cell Carcinoma of the Nasal Vestibule

Start date: December 1, 2022
Study type: Observational [Patient Registry]

The goal of this observational study is to learn about survival and prognostic factors in patients who underwent surgical treatment for primary squamous cell carcinoma of the nasal vestibule. The main questions it aims to answer are: - what is the prognosis of patients affected by squamous cell carcinoma of the nasal vestibule? - are there any specific factors that could influence prognosis? - is it possible to elaborate a new staging system, able to overcome the limitations of the currently used ones? Data about patients, tumour and type of surgery performed will be collected. Participants will be followed-up for a minimum 6 months period after surgery.

Pulse is a randomized non-inferiority phase III clinical trial assessing a new mode of immunotherapy administration based on increased interval time between 2 infusions as maintenance treatment in Pulse arm compared with the conventional administration in Control arm. In both treatment arms, pembrolizumab alone or combined with pemetrexed is allowed as maintenance treatment. Indeed : In Pulse arm : Pembrolizumab 200 mg will be administered to patients every 6 weeks (Q6W) plus, in the absence of contra-indication pemetrexed 500 mg/m^2 will be administered every 3 weeks (Q3W). In control arm : Pembrolizumab 200 mg will be administered to patients every 3 weeks (Q3W) or 400 mg every 6 weeks plus,in the absence of contra-indication pemetrexed 500 mg/m^2 will be administered every 3 weeks (Q3W).

NCT ID: NCT05692310 Not yet recruiting - Medical Imaging Clinical Trials

Study of the Effectiveness of Central Line Placement Using an Ultraportable Ultrasound Device

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

The placement of a catheter in a large-caliber vein is sometimes necessary for the administration of treatments or the monitoring of a patient. This may be associated with complications during its realization, such as the puncture of an adjacent artery with possible formation of a hematoma or the puncture of the pleura with creation of a pneumothorax. These complications may be favored by variations in the anatomy. The use of ultrasound allows visualization of the vessels, its adjacent structures and the puncture needle along its path. The contribution of ultrasound with the technique of venipuncture under ultrasound guidance is to date the best means of preventing complications by reducing the risk of early mechanical complications by a factor of 5 to 10 according to the studies. The retrospective, multicenter, observational study recently published by Björkander et al reported the experience of 8 Swedish hospitals with 14243 central venous catheter placements, 58% of which were in the internal jugular vein. Nearly one catheter in two was placed with the use of ultrasound (49%). One hundred and eighteen mechanical complications were recorded, of which 23 were considered serious, including 21 pneumothoraxes and 2 severe hemorrhages. Lack of ultrasound use was found to be an independent risk factor for complications in multivariate analysis by logistic regression. Despite a high level of evidence in the scientific literature on the contribution of ultrasound guidance for the placement of central venous catheters, and the recommendations of national and international learned societies published before the start of this study, almost one patient in two had not yet benefited from this technique, which could nevertheless greatly reduce the incidence of early mechanical complications. The recent introduction of ultra-portable ultrasound scanners could encourage the generalization of the use of ultrasound, given their reduced cost. The hypothesis of the research is that the placement of a central venous catheter is similar whether the ultrasound machine is an ultra-portable ultrasound machine or a conventional ultrasound machine

NCT ID: NCT05691777 Completed - Healthy Clinical Trials

Study of Cortical Activation During Hand and Shoulder Movements in Healthy Subjects

Start date: June 25, 2020
Study type: Observational

Characterization of cortical activation patterns during movements in healthy adults may help our understanding of how the injured brain works. Upper limb motor tasks are commonly used to assess impaired motor function and to predict recovery in individuals with neurological disorders such as stroke. This study aimed to explore cortical activation patterns associated with movements of the hand and shoulder using functional near-infrared spectroscopy (fNIRS). The investigators hypothesized that the activation pattern observed with fNIRS would differ for shoulder and hand movements. More specifically, the investigators hypothesized that the cerebral activation during hand movements would mainly involve the contralateral hemisphere, particularly the lateral part of primary motor cortex; whereas activation during shoulder movements would be more medial and more extensive than that of the hand.

NCT ID: NCT05691725 Not yet recruiting - Clinical trials for Antisynthetase Syndrome

Evaluation of Peripheral Neutrophils in Antisynthetase Syndrome

Start date: February 1, 2023
Study type: Observational

Antisynthetase syndrome (AS) is a rare overlapping myositis characterized by cellular and humoral autoimmune responses directed against aminoacyl-tRNA synthetases. A pathogenic role of neutrophils was described during inflammatory myopathies, with increased netosis correlated with disease activity and muscle damage. Higher number of alveolar neutrophils was observed in patients with rapidly progressive forms of interstitial lung disease. Peripheral neutrophils could represent a simple biomarker of severity and activity in patients with antisynthetase syndrome. The main objective is to compare circulating neutrophils between severe and non severe patients with antisynthetase syndrome. Secondary objectives are: 1) to evaluate correlation between circulating neutrophils and organ-specific severity, 2) to compare circulating neutrophils at time of diagnosis and circulating neutrophils after 6 months of treatment in patients with antisynthetase syndrome.

NCT ID: NCT05691634 Recruiting - MRI Clinical Trials

Prospective Study Evaluating the Clinical Tolerance of Skin Tattoos During MRI Examinations (TATOU - IRM)

Start date: January 30, 2023
Phase: N/A
Study type: Interventional

MRI examinations are potential sources of complications related to the displacement of ferromagnetic objects, but also to heating effects that can go as far as burns. This overheating can be caused by contact with external equipment (sensors, cables, etc.). Patients with skin tattoos may experience specific complications as tingling or "burning" felt at the site of the tattoo. They can be followed by a transient erythema with edema around the reversible tattoo in 12 and 72 hours. One observation of severe 2nd degree burns has been reported. They would be linked to the presence of metallic salts in the dermis, resulting from interactions between the pigments and the magnetic field but their mechanisms are poorly identified and divergent. The aim of this study is to assess the rate of MRI causing complications in patients with tattoos.
