The lengthy preservation time was necessary because the patient needed a liver transplant immediately prior to the lung transplant. The patient has since left the hospital and is in good health.
The OCS LUNG™ machine continually flushes and oxygenates donor lungs at room temperature.
The patient, who suffered from chronic lung failure, developed sudden acute liver problems and went into a coma. The only surgical option for a patient with a terminal lung disease and a terminal liver disease is a combined lung and liver transplant.
But such double transplants pose a serious timing problem, says Dr. Dirk Van Raemdonck, who helped perform the surgery: "Normally, the lung transplant is carried out before the liver transplant. A donor lung typically can only be preserved outside the body for a maximum of ten hours. And a lung transplant can only be successful if the liver is still working properly. That is why we needed to transplant the liver before the lungs for this patient. To keep the donor lungs in good shape long enough after removal from the donor and prior to transplantation, our medical team used a new preservation technique."
The lungs were not put on ice as they usually are, but were preserved using a machine (OCS LUNG™) that provided continual flushing and oxygen at room temperature. Dr. Van Raemdonck: "The machine enabled us to keep the lungs outside the body for more than eleven hours with no negative effects, the longest period ever reported – a world first."
The new technique enables doctors to preserve lungs outside the body longer. The machine also provides an analysis of lung quality and can even improve lung function in anticipation of the transplant. A similar machine already exists for kidneys and results show that older kidneys preserved using that machine functioned better immediately after transplantation than kidneys preserved on ice did.
Currently, however, the new technique is not being reimbursed by insurance providers. The technique is being used only in special cases. Costs for this transplantation were covered entirely by University Hospitals Leuven and the maker of the machine.
The combined lung and liver transplant was performed last July by University Hospitals Leuven's multidisciplinary transplant team, which includes specialists in hepatology (led by Dr. Frederik Nevens), abdominal transplant surgery (led by Dr. Jacques Pirenne), pneumology (led by Dr. Geert Verleden) and thoracic surgery (led by Dr. Paul De Leyn).
University Hospitals Leuven is an independent network of research hospitals affiliated with KU Leuven (University of Leuven) in Leuven, Belgium.

Today, plants and microorganisms are heavily used for the production of medicinal products. The production of biopharmaceuticals in plants, also referred to as “Molecular Pharming”, represents a continuously growing field of plant biotechnology. Preferred host organisms include yeast and crop plants, such as maize and potato – plants with high demands. With the help of a special algal strain, the research team of Prof. Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam strives to develop a more efficient and resource-saving system for the production of medicines and vaccines. They tested its practicality by synthesizing a component of a potential AIDS vaccine.
The use of plants and microorganisms to produce pharmaceuticals is nothing new. In 1982, bacteria were genetically modified to produce human insulin, a drug...
Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

The University of Würzburg has two new space projects in the pipeline which are concerned with the observation of planets and autonomous fault correction aboard satellites. The German Federal Ministry of Economic Affairs and Energy funds the projects with around 1.6 million euros.

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.
The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
