NCT ID: NCT06379139 Recruiting - Critically Ill Clinical Trials

Dynamic Full-field Optical Coherence Tomography for Structural and Microbiological Characterization of Endotracheal Tube Biofilm in Critically Ill Patients

BIOPAVIR2
Start date: March 1, 2024
Phase:
Study type: Observational

Biofilm is a microstructure organised into aggregates of microbiological species within a polymeric matrix. As early as the 2000s, the Centers for Disease Control and Prevention (CDC) recognised the possible role of the biofilm lining endotracheal endotracheal tubes in the development of ventilator-associated pneumonia (VAP) , the most common infection in intensive care, with a high morbidity and mortality rate and a significant increase in hospital costs. Targeting biofilm therefore now appears to be a new area of interest for limiting the risk of VAP, and this rationale has led to the development of an intraluminal for abrading biofilm deposited on the inside of the intubation probe . Evaluation of this type of strategy nevertheless justifies the introduction of more precise methods for characterisation of the biofilm. To this end, the investigator carried out an initial clinical study describing the biofilm on intubation probes, BIOPAVIR 1, showing the existence of several biofilm structures, each associated with a specific microbiological signature. Several limitations including a lack of power due to an insufficient number of patients and the use of number of patients, and the use of a confocal microscopy technique with poor axial without the possibility of acquiring metabolic images of the biofilm. Based on the previous description of biofilm by optical coherence tomography (OCT), and a recent experience with an optimised form of high-resolution OCT, called full-field OCT, the investigator hypothesise that full-field OCT will allow more accurate characterisation of biofilm, due to its high spatial resolution and its potential ability to capture metabolic activity in the biofilm BIOPAVIR 2 proposes to use the performance of full-field OCT to better characterise the biofilm lining endotracheal tubes in patients undergoing mechanical ventilation in intensive care units. This project represents a first step towards understanding the link between the development of biofilm on intubation and the occurrence of VAP

NCT ID: NCT06378710 Recruiting - Surgery Clinical Trials

Haemodynamic and Respiratory Effects of a Low Positive End Expiratory Pressure Associated With a Fluid Challenge in Knee-chest Position

OPTIPEP
Start date: January 20, 2023
Phase: N/A
Study type: Interventional

The genu pectoral position is a surgical position used for spine surgery. This surgical position will lead to physiological hemodynamic and respiratory changes during the procedure. The knee-pectoral position notably induces an increase in CRF and improves pulmonary ventilation/perfusion ratios. On the other hand, it has been shown that it is accompanied by a reduction in cardiac output of approximately 15% Protective perioperative ventilation including a tidal volume between 6 and 8 ml/kg of theoretical ideal weight, PEEP and alveolar recruitment maneuvers is applied in the operating room to reduce postoperative pulmonary complications. The application of high PEEP and the performance of recruitment maneuvers induce arterial hypotension through changes in intra- and transpulmonary pressures. However, investigators hypothesize that the deleterious hemodynamic effects of PEEP seem to counterbalance its beneficial respiratory effects in this particular position. The combination of the effects of the knee-pectoral position and protective ventilation could be potentiated and be the cause of the sometimes severe arterial hypotension observed in clinical practice. Since this position improves pulmonary ventilation perfusion ratios, the investigators hypothesized that a lower PEEP and the elimination of intraoperative recruitment maneuvers could be beneficial from a hemodynamic point of view without being deleterious in terms of perioperative pulmonary complications. An exploratory study was carried out at the CAEN University Hospital in 2021 under the name PEEP POSTURE (CLERS Agreement No. 2198 of February 17, 2021) on 90 patients aiming to collect hemodynamic and respiratory parameters in 3 surgical positions: supine decubitus, ventral decubitus , pectoral genu. No difference was found in the evolution of respiratory compliance. On the other hand, a significant drop in SBP, DBP and MAP in the pectoral position was shown compared to the supine group as well as greater vascular filling. The investigators therefore hypothesize that a reduction in PEEP and optimization of vascular filling could help reduce the adverse effects on blood pressure linked to the surgical position.

NCT ID: NCT06377579 Not yet recruiting - AML, Adult Clinical Trials

OBServatory of Compassionate Use of IVOsidenib in France for Patients With Acute Myeloid Leukemia

Start date: June 30, 2024
Phase:
Study type: Observational [Patient Registry]

Mutations in IDH genes are found in numerous cancers and more specifically in acute myeloid leukemia (AML). These mutations target specific amino acids, at positions 140 or 172 of IDH2, and 132 of IDH1. Mutant IDH proteins acquire an abnormal enzymatic activity allowing them to convert α-ketoglutarate (αKG) into D-2 hydroxyglutarate (D-2HG), an oncometabolite which massively accumulates in IDH-mutated cells. At high levels, D-2HG behaves as a competitive inhibitor of αKG and affects the activity of Fe(II)/αKG-dependent dioxygenases. This enzymatic family is involved in a broad spectrum of pathways such as demethylation of histone (JHDM histone demethylases) or DNA (methylcytosine hydroxylases of the TET family). As a result, IDH-mutated cells show altered survival, motility, invasiveness and cell differentiation. In AML, IDH1 mutations might be present in 10-15% at diagnosis Ivosidenib (IVO) a first-in-class, oral, irreversible inhibitor of mutant IDH1 has shown clinical activity as a single agent in studies involving patients with IDH1 mutated relapsed or refractory (R/R) AML and in front line settings. In phase II clinical trials, IVO yielded 30-35% of complete response rates both in frontline and R/R settings, with long lasting responses. Based on these results, the FDA (Food and Drug Agency) gave its approval for newly-diagnosed AML IDH1mut patients who are ≥ 75 years old or who have comorbidities and in R/R. However, European Medicines Agency (EMA)'s did not approved IVO due to lack of evidences to support the application. Agios Netherlands B.V. (the company that previously own the drug before Servier Laboratories) withdrew its EMA application. Nevertheless, IVO has been available in France through a compassionate use program (CUP), since February 2020 for R/R patients and March 2022 for first line treatment. In this multicentric retrospective study, sponsor aim to evaluate the efficacy and safety of Ivo in two cohorts of IDH1mut AML patients treated within the CUP. The first cohort will concern patients treated in first line setting and the second cohort those treated in R/R disease. Results might provide new insights regarding IVO in real life settings and support signs of efficacy. This could provide new data for the haematologist community and for another appliance to grant EMA approval of IVO in the setting of R/R IDH1mut AML.

NCT ID: NCT06376513 Not yet recruiting - Penile Prosthesis Clinical Trials

Evaluation of Penile Prosthesis Pump Manipulation

ECM3P
Start date: June 1, 2024
Phase: N/A
Study type: Interventional

Erectile dysfunction is a highly prevalent pathology. When oral or injectable pharmacological treatments prove ineffective, the treatment of choice is penile prosthesis which provides the possibility of sexual activity with penetration. Unfortunately, current prostheses are difficult (or even impossible) to manipulate for some patients. Many patients underutilize their device due to difficulties in using the pump related to mechanical issues (difficult grip, lack of strength, etc.) or sensory issues (altered proprioception, etc.), resulting in an inability to achieve rigidity that allows optimal satisfaction for the patient and/or partners. These difficulties correspond to a significant portion of dissatisfaction among patients with penile prostheses. Actually, no study has evaluated patients' ability to manipulate the pump of their penile prosthesis, as well as the association between these manipulation abilities, the rigidity of erections with a penile prosthesis, and patient and partner sexual satisfaction. In this descriptive study, the primary outcome is to describe the manipulation abilities of patients with penile prostheses during follow-up consultations after prosthesis implantation. The secondary outcomes are to estimate the association of various markers related to penile prosthesis manipulation (overall hand grip strength, pinch grip strength, proprioception, and discrimination) with - Rigidity of erections with penile prosthesis - Patient's sexual satisfaction - Partner's sexual satisfaction - Satisfaction related to pump manipulation

NCT ID: NCT06375889 Recruiting - Clinical trials for Delayed Cerebral Ischemia

Platelet Activation in Delayed Cerebral Ischemia Secondary to Aneurysmal Subarachnoid Hemorrhage

APICRASH
Start date: June 14, 2024
Phase:
Study type: Observational

Aneurysmal subarachnoid haemorrhage is a complex pathology, the pathophysiology of which is still imperfectly understood. Its morbidity and mortality remain significant. In addition to the damage sustained by the brain in the immediate aftermath of aneurysmal rupture, which is inaccessible to life-saving treatment, a significant proportion of lesions occur at a distance from the initial event. Delayed cerebral ischaemia is one of the most morbid complications. It combines an inflammatory pattern with vascular dysfunction and neuronal excitotoxicity, leading to avoidable secondary neuronal loss. Vascular dysfunction is mediated by a loss of homeostasis between endothelial cells and figurative blood cells, including platelets. However, the interrelationship between these elements and the precise chronology of the dysfunction remain imperfectly described to date. It therefore seems appropriate to propose temporal monitoring of platelet activation kinetics over time, combined with concomitant collection of markers of endothelial damage, in order to clarify the vascular chronobiology of this pathology.

NCT ID: NCT06374927 Recruiting - Stroke Clinical Trials

Personalised Health Cognitive Assistance for RehAbilitation SystEm (PHRASE): A Feasibility Study

PHRASE-2023
Start date: April 25, 2024
Phase:
Study type: Observational

The incidence of cognitive and neuromotor impairment caused by strokes has become a growing challenge. The patient's journey to recovery in the healthcare system involves multiple phases, spanning from initial hospitalization to in-patient and out-patient rehabilitation, finally leading to the patient's return to home. The access to stroke units and rehabilitation varies within Europe. Unfortunately, not everyone has access to rehabilitation programs, and the benefits derived from these programs often decline after hospital discharge. Currently, the support of the patient is organized in a rather fragmented way, and informal care sometimes places a severe burden requiring dedicated support in the patient's social environment. The PHRASE project proposes to deploy rehabilitation technology such as the Rehabilitation Gaming System (RGS) to instil and support a virtuous cycle of stroke patients' recovery in the at-home setting. RGS is an effective advanced digital tool for rehabilitation programs that uses Augmented Reality (AR)- and Virtual Reality (VR)-based gamified training grounded on neuroscientific principles, that has been shown to promote cognitive and motor recovery after a stroke at the clinic and home. There are many dedicated cognitive therapies, but most rehabilitation outcomes are mostly limited to the task trained and do not extend to day-to-day function or remain unconvincing. Based on recent literature, the PHRASE RGS-based system can provide an effective tool to address cognitive impairment using VR-based interventions. In a previous study, the neuropsychological test battery was compiled by the neuropsychologist and covered four cognitive domains: 1. basic attention, 2. memory (short-term memory), 3. visuospatial memory, and 4. executive function. All these functions were tested using VR-based tasks. The conclusion of this study confirms the possibility of addressing cognitive impairment effectively using VR-based interventions when properly mapped with clinical scales. The validation of the PHRASE system with post-stroke patients is needed to strengthen its usefulness and effectiveness for cognitive rehabilitation at home. For this, a feasibility study will be conducted to measure its usability, adherence, acceptance, and the user's experience. The investigators will also explore the effectiveness of the PHRASE system in improving cognitive function (attention, memory, executive function) after stroke. Participants: stroke patients at different time points after stroke (acute, subacute, and chronic), aged over 18 years. The participants will integrate the PHRASE technology into their daily routines in parallel to their regular neurorehabilitation treatment for 6 weeks.
