SMOKING CESSATION HIGHER WITH VARENICLINE COMPARED WITH PLACEBO IN PATIENTS WITH COPD
Bethesda, MD (March 1, 2011) — Endoscopic removal of pre-cancerous cells in patients with confirmed, high-risk Barrett's esophagus is recommended rather than surveillance, according to a new "Medical Position Statement on the Management of Barrett's Esophagus," published by the American Gastroenterological Association (AGA) Institute. The medical position statement was published in Gastroenterology, the official journal of the AGA Institute.
Lymph node dissection, the current standard surgical treatment for localized non-small cell lung cancers, may be unnecessary in certain screen-detected early stage cases , according to a study published in the March issue of the Journal of Thoracic Oncology (JTO), the official journal of the International Association for the Study of Lung Cancer.
The risk of nodal involvement is very low in early-stage cancers with a maximum standard uptake value (maxSUV) of 2.0 or a nodule smaller than 10 millimeters, researchers found.
Many longtime smokers quit spontaneously with little effort shortly before their lung cancer is diagnosed, leading some researchers to speculate that sudden cessation may be a symptom of lung cancer.
Most patients who quit did so before noticing any symptoms of cancer, according to the study, which was published in the March issue of the Journal of Thoracic Oncology (JTO), the official monthly journal of the International Association for the Study of Lung Cancer (IASLC).
An inexpensive, routine blood test could hold the key to why some patients with congestive heart failure do well after being discharged from the hospital and why others risk relapse, costly readmission or death within a year, new Johns Hopkins research suggests.
ANN ARBOR, Mich.---In the mating game, some female mites are mightier than their mates, new research at the University of Michigan and the Russian Academy of Sciences suggests. The evidence comes, in part, from 40 million-year-old mating mites preserved in Baltic amber.
In a paper published March 1 in the Biological Journal of the Linnean Society, researchers Pavel Klimov and Ekaterina Sidorchuk describe an extinct mite species in which the traditional sex roles were reversed.
ANN ARBOR, Mich.---By mimicking the structure of the silk moth's antenna, University of Michigan researchers led the development of a better nanopore---a tiny tunnel-shaped tool that could advance understanding of a class of neurodegenerative diseases that includes Alzheimer's.
Doctors should transition their patients from pediatric to adult medical care for congenital heart disease during early adolescence, experts recommend in a scientific statement published in Circulation: Journal of the American Heart Association.
Soda and other sugar-sweetened beverages such as fruit drinks are associated with higher blood pressure levels in adults, researchers report in Hypertension: Journal of the American Heart Association.
BOSTON, Feb. 28, 2011 – A change in the formulation of tenofovir gel, an anti-HIV gel developed for vaginal use, may make it safer to use in the rectum, suggests research presented today at the 18th Conference on Retroviruses and Opportunistic Infections (CROI). In laboratory tests of rectal tissue, researchers from the Microbicide Trials Network (MTN) found the reformulated gel was less harmful to the lining of the rectum than the original vaginal formulation, and just as effective in protecting cells against HIV.
Increased hospital spending at high-cost hospitals does not appear to be associated with better short-term survival rates for patients with sepsis, according to a report in the February 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Older patients are willing to take medications for cardiovascular disease prevention, but only if the drug has much more benefit than risk, according to a report published online first by the Archives of Internal Medicine, one of the JAMA/Archives journals. The paper will be published in the June 27, 2011 print issue of the journal.
Many patients, especially those with limited literacy, may self-administer prescription medications more times a day than is necessary, which may lead to missed or incorrectly administered dosing, according to a report in the February 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
