Filter by:Pancreas graft quality directly affects morbidity and mortality rates after pancreas transplantation (PTx). The criteria for pancreas graft allocation are restricted, which has decreased the number of available organs. Suitable pancreatic allografts are selected based on donor demographics, medical history, and the transplant surgeon's assessment of organ quality during procurement. Quality is assessed based on macroscopic appearance, which is biased by individual experience and personal skills. Therefore, the aim of this study is to assess the histopathological quality of unallocated pancreas organs to determine how many unallocated organs are of suitable quality for PTx, based on histopathologic evaluations. The reasons for allocation rejection will be reported and the correlation between cause of allocation rejection and histopathological quality of the allocated organ will be evaluated. This is a multicenter cross-sectional explorative study. The demographic data and medical history of donor and cause of rejection of the allocation of graft will be recorded. Organs of included donors will be explanted and macroscopic features such as weight, color, size, and stiffness will be recorded. A tissue sample of the organ will be fixed for further microscopic assessments. Histopathologic assessments will be reported 6 hours (or at time of organ delivery if later than 6 hours), 9 hours, 12 hours, 15 hours, and 18 hours after procurement. 100 pancreases will be evaluated in this study.
The aim of this study is to assess and survey the quality of the process required to diagnose brain death in adult patients. This study of adult patients diagnosed brain dead or suspected of having brain death on the ICUs at the University Hospital Basel will be purely observational.
This study aims to evaluate brain death with optical probes. The changes of hemodynamic parameters including oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) were detected by near infrared spectroscopy probes attached on the forehead of patients. A multiple-phase protocol at varied fraction of inspired O2 were utilized during the assessment.
the SafeBoosC-III trial investigates the benefit and harms of treatment based on near-infrared spectroscopy monitoring compared with treatment as usual. The hypothesis is that treatment based on near-infrared spectroscopy monitoring for extremely preterm infants during the first 72 hours of life will result in a reduction in severe brain injury or death at 36 weeks postmenstrual age.
The purpose of this study is to make a paramedical evaluation of a selection procedure of serious brain-injured patient in therapeutic abstention to a brain death state within 48 hours.
Current standard of care prior to determination of brain death in subjects with suspected anoxic brain injury is to exclude complicating medical conditions that may confound clinical assessment (such as severe electrolyte, acid base, endocrine or circulatory disturbance), achieve normothermia and normal systolic blood pressure over 100 mmHg (with or without vasopressor use), exclude the presence of neuromuscular blocking agents (with the presence of a train of 4 twitches with maximal ulnar nerve stimulation) as well as to exclude the presence of CNS depressant drug effects. At the present time the latter is done by history, drug screen and allowing enough time for paralytic and sedative drugs to be metabolized and cleared from the body. Clearance is calculated by using 5 times the drug's half-life assuming normal hepatic and renal functions. Half-life can also be prolonged in subjects who have been treated with induced hypothermia. Literature search revealed articles with general guidelines and approaches to brain death, but none addressed pharmacological reversal of sedative drugs
There is evidence of the association of brain death and inflammation, affecting outcomes of transplanted organs, but in a way not fully understood. Observational studies suggest that the use of target-guided therapies has a beneficial effect in reducing the rate of donor loss due to cardiac arrest and increasing the rate of donor-picked organs, which will be tested through the randomized clinical trial. However, no study so far has directly tested the effect of drugs with anti-inflammatory and anti-apoptotic properties administered to the donor in encephalic death in reducing inflammation of organs to be transplanted. This study aims to evaluate the use of liraglutide in patients with brain death in relation to their ability to attenuate the inflammation induced by encephalic death by means of a randomized clinical trial.
There is currently a shortage of organ in France, for patients with chronic diseases who are on the waiting list for an organ. The first source of organ donor in France is patients with brain death. 58% of patients in brain death are patients with a severe stroke ( ischemic or hemorrhagic). In order to identify which patient with a severe stroke and with unfavorable prognosis who can evolve to brain death, we have conducted a retrospective study in Lorrain, in France, and we have built a predictive score of brain death in these patients. It is important to validate this predictive score in a prospective study on a greater scale than the first study.
The aim of this study is to gather information about knowledge, professional experience and attitude toward organ donation among health care professionals involved in the care of potential donors about the procurement process and potential lung donor management nationwide.
The primary goal of this study is to assess whether ventilation of deceased organ donors with an open lung protective ventilatory strategy will improve donor lung utilization rates and donor oxygenation compared to a conventional ventilatory strategy.
