Like their younger counterparts, some elderly patients who have early stage non-small cell lung cancer can benefit from a minimally invasive surgical procedure to remove part or all of a lung, according to a study conducted by thoracic surgeons at Cedars-Sinai Medical Center and described in The American Surgeon, the journal of the Southeastern Surgical Congress and the Southern California Chapter of the American College of Surgeons.
When non-small cell lung cancers (NSCLC) are detected at an early, localized stage, surgical removal of the affected area often can prevent metastasis to other tissues and organs. But while some patients, including the elderly, might not be good candidates for the physical demands of open chest surgery, this study of 159 patients between ages 80 and 94 suggests that video-assisted thoracoscopic surgery should be considered a viable option.
"Some patients and their doctors wonder why a person that age should bother to go through any major pulmonary surgery. The reason is that whether the patient is 80 or 95, if they are in reasonably good physical condition without any other major medical problems that are imminently life threatening, the odds are that the cancer is going to progress and the patient will live long enough to go through several unpleasant months with widespread cancer," said Robert McKenna Jr., M.D., thoracic surgeon, surgical director of the Center for Chest Diseases and chief of Thoracic Surgery and Trauma at Cedars-Sinai.

Penn study identifies new malaria parasites in wild bonobos
21.11.2017 | University of Pennsylvania School of Medicine
The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
