NCT ID: NCT04125069 Completed - Clinical trials for Patients Undergoing Coronary Artery Bypass Graft (CABG) Surgery Requiring Extracorporeal Circulation

Role of Mitochondrial Dysfunction in the Occurrence of Acute Kidney Injury (AKI) in Postoperative Cardiac Surgery

MIT-CEC
Start date: October 2, 2019
Phase:
Study type: Observational

Cardiac Surgery and Acute Kidney Failure (AKI) post Surgery: AKI is a frequent complication in the immediate aftermath of cardiac surgery with an incidence varying from 5 to 40%. KDIGO criteria (Kidney Disease: Improving Global Outcomes) are used to define the AKI in cardiac surgery because of their validated prognostic value in this patient population. The occurrence of a postoperative AKI, even of low severity, is accompanied by a significant increase in the duration of hospitalization and mortality. The AKI risk factors in cardiac surgery are related to the precarious clinical conditions of the patient before the surgery, to the complex surgical context, to the surgical procedures particularly the duration of extracorporeal circulation (ECC) greater than 120 min and the occurrence of a postoperative circulatory insufficiency. AKI and inflammatory response: The mechanisms involved in postoperative AKI in cardiac surgery, are low cardiac output, ischemia reperfusion injury (IRI), mechanical intravascular hemolysis, hypothermia, and activation of the neuroendocrine system by the ECC. In addition, ECC triggers a secondary inflammatory response to blood contact with the ECC circuit and membranes. The secondary stimulation of immunocompetent cells accompanies secretion of many cytokines and proinflammatory mediators via the activation of nuclear transcription factors as the NFκB factor. Of the 50 000 ECC performed per year in France, about 25% of the patients develop a Systemic Inflammatory Response Syndrome (SIRS). Although most often transient, SIRS can intensify and lead to a multi-visceral failure and to death, especially if the patient presents medical history of type 2 diabete. Increase of postoperative plasma cytokine levels has a positive predictive value on the occurrence of AKI and the risk of death. Priming of the NLRP3 inflammasome and post ECC inflammatory response: In addition to activation by nuclear transcription factors (NFκB), the inflammatory syndrome may develop secondarily to the activation of multi-protein platforms, called inflammasomes. The activation of the NLRP3 inflammasome has been particularly studied in humans because of its association with multiple chronic inflammatory pathologies, infectious and cardio-metabolic diseases. Its activation is the combination of intracellular receptors like NOD-like receptors (NLR) types, ASC-like adapter proteins and pro caspase-1. This assembly activates inflammatory caspases (caspase-1, in particular) responsible for the cleavage of pro-interleukins IL-1β and IL-18 in mature pro-inflammatory cytokines that participate in the orchestration of the inflammatory response. Activation of the NLRP3 inflammasome requires prior priming which allows increase of NLRP3 and pro-cytokines IL1β and IL18 expressions. This priming is particularly intense in the presence of a mitochondrial dysfunction and of an increase in reactive oxygen species (ROS). Next, the activation of the NLRP3 inflammasome may be secondary to the presence of danger signals from cellular damages, such as cellular and mitochondrial debris (including mitochondrial DNA) recognized by NLRP3 receptors. Thus, preoperative mitochondrial dysfunction and its postoperative aggravation by ECC due to IRI induced by ECC represents powerful signals ,of the NLRP3 inflammasome activation. Research hypothesis: The hypothesis is that the preoperative priming of the NLRP3 inflammasome by a preoperative mitochondrial dysfunction is a factor favoring the occurrence of postoperative AKI after cardiac surgery with ECC. For type 2 diabetic patients, the investigators think that preoperative mitochondrial dysfunction (mitochondrial respiration abnormalities and hyperpermeability of mitochondrial membranes) is accentuated worsening IRI induced by the ECC. This increases postoperative release of cells and mitochondrial debris that maintain the activation of the NLRP3 inflammasome, exacerbating the inflammatory response and favoring the occurrence of AKI.

NCT ID: NCT04124523 Completed - Clinical trials for Cerebrospinal Fluid Leak

Perioperative CSF Leak Management - an Opinion Study

Start date: January 1, 2019
Phase:
Study type: Observational

Cerebrospinal fluid (CSF) leak is a rare condition. When it involves the ventral skull base, a surgical closure may be achieved using endoscopic skull base surgery techniques. The major principles remain in achieving a watertight closure that can also support the brain (and avoid brain sagging) in case of extensive skull base defects. Surgical techniques are well described. Many clinical factors may influence the successful rate of the reconstruction. However, there is a lack of clinical study on perioperative management of CSF leaks. The purpose of this study is to gather the opinion of skull base surgeons on the post-operative management of patients to avoid CSF leak recurrence. •Methods: The investigators will collect data from skull base surgeons using an electronic survey questionnaire (Google Form, Google, Mountain View, California, U.S.A.) submitted by e-mail to the members of the French Association of Rhinology, to the European Rhinologic Society, to the French college of neurosurgeons, to the Italian skull base society members, and to the former students of the European endoscopic skull base diploma. This is an anonymous 60-items survey. Questions were classified in eight sections: general questions, material used at the end of the surgical procedure, post-operative resting position, drugs, CSF depletion, post-operative advices, explorations in case of early recurrence of the rhinorrhoea, and follow-up modalities. •Discussion: The investigators aim to understand the actual practice of skull base surgeons after closure of ventral skull base CSF leaks. This can serve as a basis for conducting clinical studies in the future.

NCT ID: NCT04120727 Completed - Clinical trials for Osteoarthritis, Knee

Evaluation of the Brakes and Levers on the Use of an E-health Application for Osteoarthritis Patients

ARTHe-1
Start date: July 1, 2019
Phase:
Study type: Observational

Osteoarthritis is the most common articular disease affecting the joint in a comprehensive and progressive manner. It is a chronic pathology correlated with age since nearly one in two adults is affected by osteoarthritis. The care of osteoarthritis is based on pharmacological and non-pharmacological treatment. The latest recommendations support the non-pharmacological part including regular physical activity, therapeutic education and weight loss. Today tools are lacking for the patient and the practitioner to ensure long-term motivation and support. Connected objects, as future-oriented tools, are a customizable way to meet the expectations of both patients and professionals. The main objective of this study is to analyze the expectations regarding the use of a smartphone application for monitoring and support in the practice of exercises and regular physical activity in patients osteoarthritic. The secondary objective is to collect information on the use of connected objects dedicated to the management of osteoarthritis by patients and health professionals.
