Adjuvant chemotherapy improves survival in early-stage ovarian cancer

Results from two large European studies suggest that adjuvant chemotherapy immediately after surgery for early-stage ovarian cancer can increase some patients’ chances of both overall and recurrence-free survival. The findings are reported in three articles in the January 15 issue of the Journal of the National Cancer Institute.

As many as 50% of patients with early-stage ovarian cancer relapse after surgery, and these subsequent tumor recurrences are often resistant to treatment. Adju

Artificial disc available to more patients as spine institute takes study to next phase

An artificial disc being studied as a replacement for damaged discs of the spine has been approved to move into Phase II trials, making it available to more patients, according to John J. Regan, M.D., director of Cedars-Sinai Medical Center’s Institute for Spinal Disorders. A recently completed Phase I study compared the prosthesis to traditional fusion. In that phase, patients were randomized, with one having a fusion operation for every two that received the artificial disc. Now all patien

Superconducting sensor helps detecting gravitation waves

To be able to detect gravitation waves in space, physicist have to measure truly minimal displacements: ten billion times smaller than the size of an atom. An improved superconducting sensor is a suitable candidate for this job, Martin Podt of the University of Twente now states in his PhD thesis. He has improved the sensitivity of a so-called ‘SQUID’ in way that it can be combined with a large ball-shaped gravitation detector. Podt succeeds in this by improving the sensitivity. He integrates the sen

Scientists hone in on causes of amphibian deformities

A dramatic increase in deformed frogs and other amphibians is being caused by a range of environmental factors, all of which ultimately can be linked to human impacts on habitat, but the primary cause of many of the deformities is an epidemic of a key parasite.

These findings are the results of eight years of research by scientists around the world, and are presented in the February issue of Scientific American by researchers from Oregon State University and the University of Wisconsin.

Rare Asian dolphin threatened by human activities

A rare dolphin species known for assisting fishermen by driving fish into their nets may soon disappear from the great Asian river for which the animals are named. According to a recent scientific survey by the Wildlife Conservation Society (WCS) and its partners, the Irrawaddy dolphin may vanish from the Ayeyarwady River (formerly Irrawaddy) without efforts to protect these aquatic mammals from human activities along the river.

A research team with members from WCS, WDCS (the Whale and Dol

Communication technique may improve health outcomes

Simple communication technique may improve health outcomes among diabetes patients, but is underused by physicians

Diabetes management may improve when physicians use an interactive communication technique with patients. Unfortunately, physicians underuse this simple strategy, according to a new study, which appears in the January 13, 2003 issue of The Archives of Internal Medicine.

Prior research has shown that patients fail to recall or comprehend as much as half of what t
