A new study has found that many older lung cancer patients get treatments that may not help them live longer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings suggest that physicians should not routinely use radiation after surgery to treat lung cancer that is advanced but has not widely spread, at least in older patients.

Researchers from Mount Sinai School of Medicine have found that post-operative radiation therapy (PORT), a controversial yet frequently administered treatment for lung cancer, may not prolong life in older people with locally advanced disease. The findings appear in the February 13 online edition of Cancer, a peer-reviewed journal of the American Cancer Society.
New research reports that incident malignancy among children with juvenile idiopathic arthritis (JIA) is four times higher than in those without the disease. Findings now available in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR), suggest JIA treatment, such as tumor necrosis factor (TNF) inhibitors, does not necessarily explain the development of cancer in this pediatric population.
Researchers from Mount Sinai School of Medicine have found that laws permitting children to stay on their parents' health insurance through age 26 result in improved access to health care compared to states without those laws. This analysis indicates the potential positive impact of a key provision of the Patient Protection and Affordable Care Act of 2010 (ACA). The study appears in the March issue of the journal Pediatrics, the official journal of the American Academy of Pediatrics.
CAMBRIDGE, Mass. (February 12, 2012) – To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie's Hercule Poirot and Arthur Conan Doyle's Sherlock Holmes, Tomomi Kiyomitsu used his keen powers of observation to solve a puzzle that had mystified researchers for years: in a cell undergoing mitotic cell division, what internal signals cause its chromosomes to align on a center axis?
BOSTON, Mass. (February 12, 2012)—For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan, from a type of hydrangea that grows in Tibet and Nepal. More recent studies suggest that halofuginone, a compound derived from this extract's bioactive ingredient, could be used to treat many autoimmune disorders as well. Now, researchers from the Harvard School of Dental Medicine have discovered the molecular secrets behind this herbal extract's power.
Researchers from the University of Geneva (UNIGE), Switzerland, have discovered the crucial role of two proteins in developing a cell 'anti-enzyme shield'. This protection system, which operates at the level of molecular 'caps' named telomeres, prevents cells from treating chromosome ends like accidental DNA breaks and 'repairing' them. Joining chromosome ends would, indeed, lead to tumor formation. This study, carried out by Cyril Ribeyre and led by David Shore, professor of molecular biology, is published in the revue Nature Structural & Molecular Biology.
A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate, according to research published online in Nature Immunology.
NEW YORK -- A novel discovery by researchers at NYU Langone Medical Center and colleagues reveals a mechanism by which the immune system tries to halt the spread of HIV. Harnessing this mechanism may open up new paths for therapeutic research aimed at slowing the virus' progression to AIDS. The study appears online ahead of print today in Nature Immunology.
February 12, 2012, Shenzhen, China – In a new study published online in Nature Biotechnology, researchers from BGI, the world's largest genomics organization, reported the evidence of extensive RNA editing in a human cell line by analysis of RNA-seq data, demonstrating the need for new robust methods to identify important post-transcriptional editing events.
GALVESTON, February 7, 2012 – The longer a Hispanic woman lives in the United States, the higher her risk of preterm birth (PTB), with nearly half of PTBs among Hispanic women occurring in those who were born in the U.S.
This is the main finding of a study by researchers at the University of Texas Medical Branch (UTMB) at Galveston who sought to shed light on possible environmental factors in PTB. It is one of several studies from UTMB presented this week at the Society for Maternal-Fetal Medicine's (SMFM) 32nd Annual Meeting in Dallas.
DALLAS (February 11, 2012) — In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in Dallas, Texas, researchers will report findings that show that short therapy with the anti-diabetic medication Pioglitazone can prevent the long term effects of maternal obesity on offspring.
DALLAS (February 11, 2012) — In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in Dallas, Texas, researchers will report findings that indicate that elevated levels of cell-free DNA in the first trimester do not predict the subsequent development of preeclampsia.
SAN FRANCISCO, CA – Primary Anterior Cruciate Ligament (ACL) reconstruction improves quality of life and sports functionality for athletes, according to research presented today at the American Orthopaedic Society for Sports Medicine's Specialty Day in San Francisco, CA.
SAN FRANCISCO, CA - The use of epidural steroid injections may be a more efficient treatment option for lumbar disc herniations, according to research presented today at the American Orthopaedic Society for Sports Medicine's Specialty Day in San Francisco.
