NCT ID: NCT06183398 Recruiting - Food Allergy Clinical Trials

Analysis of the Prevalence of Sensitization to Plants Containing Gibberellins Using Realistic Skin Prick Tests

GIBBERELLINS
Start date: March 14, 2024
Phase: N/A
Study type: Interventional

Gibberellin-related proteins (GRPs) are proteins contained in both pollens and vegetables and are associated with an increased risk of severe food allergy reactions. The best characterized one the only one for which a specific IgE (Immunoglobulin E) may be dosed in current clinical practice is Pru p 7, an allergen contained in peaches (Prunus persica). Sensitization to GRPs seems to be greater in areas with high exposure to pollens of the Cupressaceae family (as in the Montpellier region in Southern France); a subtype of Cupressaceae pollinosis, characterized by sensitization to Pru p 7 has been shown to be responsible for severe peach allergies. To date, there has been no real analysis of the prevalence of sensitization to GRPs, or of possible cross-sensitization between plants and foods containing GRPs. Main food containing GRPs with a high level of homology with Pru p 7 include apples (Malus domestica, 97.3%), sesame (Sesamum indicum, 91.9%), carrots (Daucus carota subsp. Sativus, 88.9%), lemons and oranges (different species, with a homology of 87.3%). If investigators consider that sensitization to GRPs could be associated with severe allergic hypersensitivity reactions, it is important to detect the prevalence of sensitization to these allergens and to find sensitization profiles for these patients in order to gain a better understanding of this type of allergy and offer a more appropriate and preventive management to allergic patients. This remains today a major challenge for the allergy community in the Mediterranean region. This study aims to investigate the rate of sensitization to peach and 5 other allergens containing gibberellins, chosen on the basis of their homology with Pru p 7 (the gibberellin from Prunus persica): carrot, lemon, orange, apple and sesame.

NCT ID: NCT06183385 Not yet recruiting - Sexual Assault Clinical Trials

Detection of Saliva by Immunoaffinity and Mass Spectrometry

SIMS
Start date: January 15, 2024
Phase: N/A
Study type: Interventional

The identification of saliva in genital area during a criminal investigation can be a critical component in the prosecution of a sexual assault in France, as non-consensual oral-genital intercourses have been considered as crimes since 2021.The development of highly specific methods for saliva detection is therefore crucial as the commonly employed screening methods lack specificity. Protein mass spectrometry has proven to be a sensitive and specific method but is particularly time consuming. A faster and more sensitive hybrid approach using automated immunoaffinity mass spectrometry (IP-LC-MS/MS) has been recently developed and has been found to be particularly performant for the detection of a seminal fluid protein (semenogelin), allowing a high-throughput seminal fluid identification in semen samples. Like semenogelin, specific salivary proteins such as histatin type 1, cystatin D or proline-rich proteins (PRPs) could be detected using this promising approach, which has never been tested on saliva samples. In collaboration with the Clinical Proteomics Platform and the Department of Reproductive Medicine of the University Hospital of Montpellier, we aim to develop a protocol for the detection of specific saliva proteins by IP-LC-MS/MS in sexual assault-type samples.

NCT ID: NCT06182956 Not yet recruiting - Clinical trials for Interstitial Lung Disease

NIV Versus HFO for Acute Exacerbations of Interstitial Lung Diseases

IRAPIDPhysio
Start date: January 1, 2024
Phase: N/A
Study type: Interventional

The objectives of this study are to compare the physiological consequences of high-flow oxygen therapy and noninvasive mechanical ventilation on ventilation, respiratory work and hemodynamics during acute respiratory failure in diffuse interstitial pneumonia.

NCT ID: NCT06182748 Not yet recruiting - Clinical trials for Fibrotic Interstitial Lungs Diseases

Physical Activity and Fibrosing Interstitial Lung Disease

AP-PID
Start date: December 2023
Phase: N/A
Study type: Interventional

Fibrotic interstitial lungs diseases (ILD) are a group of chronic and rare diseases characterized by an altered blood oxygenation in the lung, leading to dyspnea and physical limitation. Physical training is efficient to fight vicious circle of physical deconditioning observed in ILD. Eccentric cycling is an interesting modality of endurance training, allowing better exercise tolerance and adherence while developing cardiorespiratory function. Feasibility and efficacity of eccentric cycling were shown in chronic obstructive pulmonary disease but never in ILD. The primary aim of our work is to compare concentric and eccentric cycling training on physical capacities in ILD. Moreover, we will study the effects of training on the different steps of oxygen transport at exercise, from the lung to the muscles through the blood transport. Our second goal is then to characterize the physiological mechanisms underlying the benefits of exercising in ILD patients. Evaluations will be led during one year to study the long-term effects of training

NCT ID: NCT06182514 Recruiting - Clinical trials for Reasons for Emergency Calls

What Are the Main Themes Concerned by the Second-line SMUR 67, Known as Reinforcements, in the Bas-Rhin Sector

RenforSMUR
Start date: July 1, 2022
Phase:
Study type: Observational

In this study the investigators wish to evaluate the possibility of anticipating the requests for SMUR reinforcement within the SAMU67. The studied population concerns each patient having benefited from an SMUR at the time of his pre-hospital care. The investigators expect from this study an improvement of the assumption of responsibility of the patients in the future with optimization of the delay of sending of an SMUR when this one is necessary.

NCT ID: NCT06182501 Recruiting - Clinical trials for Resistance to Activated Protein C in the Determination of Protein S Activity

Interference by Activated Protein C Resistance in the Determination of Protein S Activity

PS
Start date: July 1, 2022
Phase:
Study type: Observational

Protein S is an anticoagulant protein and a cofactor of protein C. It is recommended to explore it first by a functional (chronometric) technique by assessing its cofactor activity of activated protein C. Existing tests measure the prolongation of a coagulation time. These tests are all dependent on factor V, but some patients have mutations in factor V (including V Leiden) that make them resistant to activated protein C activity. It is suspected that these mutations lead to underestimations of protein S activity by chronometric technique.

NCT ID: NCT06182254 Recruiting - Surgery Clinical Trials

Personalized Perioperative Care Based on Patient Reported Outcomes Measures

SUPPORT
Start date: April 14, 2023
Phase: N/A
Study type: Interventional

In the perioperative setting, Patient Reported Outcomes Measures (PROMs) are important for both patients and clinicians. Reliable PROMs, like the Quality Of Recovery 15 (QoR-15) questionnaire, are available for patients experiencing surgery. These PROMs are significantly used as endoints for clinical interventions assessment. These PROMs may also be considered to monitor and assess patient health status as part of enhanced recovery after surgery pathway. However data about the efficacy of PROMs-based perioperative clinical follow up are lacking. The clinical hypothesis is that a PROMs (QoR-15) based perioperative clinical care is more efficient that the usual care non based on the QoR-15.

NCT ID: NCT06181981 Recruiting - Clinical trials for Magnetic Resonance Imaging

Leucoaraiosis and Multimodal MRI With Fingerprinting Technique

LEUKOPRINT
Start date: November 14, 2022
Phase:
Study type: Observational

Leukoaraiosis (LA) corresponds to an alteration of the encephalic white matter, linked to chronic hypoxia. Its pathophysiology, which has been partially elucidated, is underpinned by chronic changes in the walls of small-caliber perforating arteries, leading to chronic hypoperfusion of the white matter, associated with dysfunction of the blood-brain barrier. In affected areas, this process leads to myelin rarefaction, axonal loss, perivascular alterations and the appearance of cavitation zones. Its existence is mainly linked to the presence of vascular risk factors, most notably arterial hypertension. MR fingerprinting is an innovative Magnetic resonance Imaging (MRI) technique allowing to obtain a multiparametric MRI sequence in a non-invasively way and in a single acquisition, generating not only multiple contrasts, but also absolute longitudinal relaxation time (T1) and transverse relaxation time (T2) mappings (T1 and T2 mapping). However, the prognostic role of these T2 values, in terms of ischemic, hemorrhagic and cognitive risk, has never been studied. The objective of this study is to study and compare changes in T1 and T2 values of White Matter Hyperintensities (WMH) and Normal Appearing White Matter (NAWM) in subjects with LA.

NCT ID: NCT06181565 Completed - Clinical trials for Bypass Graft Stenosis

The Impact of Pericardial Closure on the Grafts, in the Context of Coronary Artery Bypass Grafting

Start date: January 1, 2022
Phase:
Study type: Observational

Once the pericardium is closed, there is no information on the hemodynamics of the grafts after coronary artery bypass grafting. This would be the reason for different opinions on pericardial closure: some teams do not close the pericardium and others close it. In the department Cardiovascular Surgery of the University Hospital of Saint-Etienne, the Medistim machine is used in routine and the hemodynamic properties of the grafts are recorded immediately after the bypass surgery, before the closure of the pericardium.

NCT ID: NCT06181357 Recruiting - COPD Clinical Trials

Trial Evaluating the Rate of Pneumothorax in Severe Emphysema Secondary to Endoscopic Volume Reduction With Two-stage ZEPHYR® Valves Versus Endoscopic Volume Reduction With One-stage ZEPHYR® Valves

REPEAT
Start date: May 6, 2024
Phase: N/A
Study type: Interventional

Chronic obstructive pulmonary disease (COPD) affects 3.5 million people and is the third leading cause of death worldwide. Emphysema involves air retention in the lungs and is ultimately responsible for a major deterioration in the quality of life. Available drug treatments have moderate efficacy whereas surgical lung volume reduction can improve exercise capacity when offered to a very selected population but at the cost of significant morbidity and mortality. Endoscopic Lung Volume reduction with ZEPHYR® valves improves respiratory function at rest, exercise tolerance and quality of life in patients with little or no interlobar collateral ventilation. If this technique has therefore proven its effectiveness, it is not devoid of complications and is notably responsible for pneumothorax in 27% of cases. The management of this complication is clearly codified, ranging from patient monitoring to the removal of one or more valves. It is therefore a subject of major concern for multiple reasons: high incidence, lengthening of hospital stay, increase in the overall cost of care, potential loss of benefit for the patient in the event of permanent withdrawal. valves and above all a potentially fatal event. A new strategy for implanting ZEPHYR® valves in two stages has been developed in Limoges University Hospital. This innovative algorithm has been evaluated in several non-comparative single or multicenter studies. In those studies, pneumothorax' rate secondary to lung volume reduction with endobronchial valves is rated between 4.5 and 12%. The efficacy of the treatment appears to be comparable with the data found in the trials evaluating in which the entire lobe was treated in one procedure. Moreover, despite two procedures, there does not seem to be any increased risk of occurrence of other complications. Finally, the systematic scheduling of a thoracic computed tomography between the two procedures showed that 26.6% of patients presented a reduction in volume greater than 350mL despite incomplete treatment. These data seem promising but no direct comparison with standard one-step treatment has ever been conducted so far.
