Two studies in the February 1 issue of the Journal of the National Cancer Institute examine whether hospital volume, surgeon experience, or surgeon specialty affect the treatment received and the risk of death following treatment among women with ovarian cancer.
Past studies have suggested that patients treated at hospitals with higher case loads or by more experienced surgeons have higher survival rates after surgery for certain types of cancer, including colorectal cancer and lung cancer. Patients may take such factors into account when making decisions about where and from whom to seek medical care.
Ovarian cancer ranks fourth in cancer death in U.S. women and was expected to have claimed more than 16,000 lives in 2004. It is typically a disease of women in their sixth or seventh decade. To examine the association between hospital case volume and procedure-specific experience of surgeons on outcomes after ovarian cancer surgery, Deborah Schrag, M.D., of the Memorial-Sloan Kettering Cancer Center in New York City, and colleagues used the Surveillance, Epidemiology, and End Results (SEER)–Medicare linked database to identify 2952 patients age 65 or older who had surgery for primary ovarian cancer between 1992 and 1999. They looked at both short-term (60-day) and longer term (2-year) mortality rates and overall survival.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
