Filter by:Pulmonary transplantation is the reference treatment for chronic terminal respiratory failure in patients with cystic fibrosis. These are mainly bi-pulmonary transplants (cardiopulmonary transplants are exceptional). The annual number of pulmonary transplants in France for cystic fibrosis is about 90. In 2013, the transplant involves a total of more than 600 patients with cystic fibrosis. The average age at the time of the transplant is 28.5 years (2013 data, French cystic fibrosis register), compared to 58 years for patients transplanted to all pathologies. Cystic fibrosis accounts for 25% of adult bi-pulmonary grafts. Pediatric transplants are currently very rare. The median survival after pulmonary transplantation in cystic fibrosis is currently 8.5 years (and 10 years when considering patients surviving 3 months, ie excluding early mortality). Cystic fibrosis is the pathology associated with better survival after pulmonary transplantation given the young age of patients (28.5 years on average). The non-respiratory comorbidities associated with transplantation, all underlying pathologies combined, and referenced in the Registry of the International Society for Heart and Lung Transplantation (ISHLT) are: hypertension, diabetes, renal insufficiency, Dyslipidemia, cancers. Their frequency increases with the survival time of transplanted patients. Cystic fibrosis is associated with non-respiratory comorbidities, the frequency of which increases with age - diabetes, osteoporosis, renal insufficiency, hepatopathy, neoplastic pathologies - and may become worse after transplantation. The main objective is to estimate the incidence of non-respiratory co-morbidities after lung transplantation in the cohort of patients with cystic fibrosis grafted in the Rhône-Alpes region.
An injury of haematosis in post ischemic chronic heart failure limits the clinic tolerance. There is a correlation between injury of pulmonary diffusing, chronic heart failure intensity and aerobic physic ability evaluated by an heart-rate maximal exercise tolerance test (VO2 max). This injury is a new follow-up parameter of cardiac function for the adult. The nature of damage (vascular or membrane) can be determined by the measure of double pulmonary diffusing capacity to carbon monoxide (CO) associated to nitric oxide (NO). Today, in chronic heart failure consecutive to a congenital heart disease, there is no data on evolution of membrane and capillar factors.It is impossible to predict if membrane damage will be the best factor correlated to the VO2max in patients suffering from complex congenital heart disease. Assessing these parameters could be an comparative evaluation of heart-rate exercise tolerance test with VO2max and an early control of his damage without risks related to heart-rate maximal exercise and independently of age, sex, hemoglobin, type of heart disease.These results would have an early prognostic value that would permit to refine the follow-up and the treatment. The main objective of this trial is to assess the statistic correlation between the membrane injury of alveolar-capillary diffusing at rest and aerobic physic ability restriction in children and adults suffering from complex congenital heart disease.
Prospective Evaluation of a RIsk Score for postoperative pulmonary COmPlications in Europe (PERISCOPE) is a multi-centre, international observational study of a random-sample cohort of patients undergoing a nonobstetric in-hospital surgical procedure under general or regional anaesthesia during a continued 7-day period of recruitment.
Remote ischemic preconditioning (RIPC) occurs when a tissue (ex. heart) becomes less vulnerable to an ischemic insult if a remote tissue (ex. arm) has had previous exposure to a period of ischemia and reperfusion. A beneficial effect of RIPC has been demonstrated in several randomized studies in patients undergoing cardiac and vascular surgery, as well as interventional cardiac procedures such as angioplasty. They have shown improvements in cardiac, renal, neurologic and respiratory function. Most have focused on surrogate outcomes, such as biochemical markers of cardiac and renal function in low-risk patients. No trials have investigated only high-risk patients or been designed to detect clinical outcomes. This study is a randomized-controlled trial powered to detect clinical events in a high-risk cohort undergoing cardiovascular surgery. Patients will be randomized to RIPC (exposed to cycles of inflation of a blood pressure cuff on the upper arm prior to undergoing surgery) or control (no ischemic stimulus). The investigators hypothesize this population will demonstrate lower rates of adverse ischemic events. The investigators also intend to sample biochemical markers to better elucidate the mechanism of RIPC and generate hypotheses for future studies and interventions. Post-operatively the investigators will monitor for adverse clinical outcomes including cardiac, renal, pulmonary and neurologic injury. RIPC is simple, inexpensive and easily reproducible and there have been no reports of adverse consequences. Post-operative ischemic events such as stroke, myocardial infarction, cardiac, renal and respiratory failure affect patient survival and quality of life, and represent a sizeable financial burden to health care. If beneficial effects of RIPC are demonstrated, it will be widely applicable to the entire population of cardiac and vascular patients resulting in a widely-implemented change in practice.
Levels of tocotrienol in human tissues following supplementation is not currently known. The objective of this present study is to determine the levels of this form of vitamin E in the human tissues such as skin, heart, lung, liver, adipose tissue, Brain and cerebrospinal fluid (CSF) following oral supplementation
