JAMA Commentary
Highlights How to Improve U.S. Health Care
from MedScape Medical News
Methods to
improve and transform the way U.S. health care is provided by front-line
clinicians are highlighted in a commentary published in the Feb. 18 issue of
JAMA. Recommended strategies include quality measurement, health information
technology (HIT), comparative effectiveness of devices and medication, quality
improvement collaborative, learning networks, and clinician training. More
Antibodies Offer a New Path for Fighting Flu
from The New York Times
In a discovery
that could radically change how the world fights influenza, researchers have
engineered antibodies that protect against many strains of the virus, including
even the 1918 Spanish flu and the H5N1 bird flu. The discovery, experts said,
could lead to the development of a flu vaccine that would not have to be changed
yearly. And the antibodies already developed can be injected as a treatment,
going after the virus in ways that drugs like Tamiflu do not. More
An Emergency Room Built Specially For Seniors
from NPR
For years, many hospitals have
set up separate emergency rooms just for kids. Now, Holy Cross Hospital in
Silver Spring, Md., has set up an ER specifically for patients 65 and older. The
ER opened last November and takes older patients, unless they're considered
trauma patients. More
What's Feeding Cancer Cells?
from Science Daily
Cancer cells need a
lot of nutrients to multiply and survive. While much is understood about how
cancer cells use blood sugar to make energy, not much is known about how they
get other nutrients. Now, researchers at the Johns Hopkins University School of
Medicine have discovered how the Myc cancer-promoting gene uses microRNAs to
control the use of glutamine, a major energy source. More
Psoriasis Drug
Linked to Deaths From Progressive Multifocal
Leukoencephalopathy
from MedScape Medical News
Three deaths
from progressive multifocal leukoencephalopathy (PML) and a possible fourth case
have been reported in patients taking the immunosuppressant drug efalizumab
(Raptiva, Genentech, Inc), according to a public health advisory issued recently
by the U.S. Food and Drug Administration. According to the FDA, all four
patients had been taking efalizumab for at least three years and had taken no
other immunosuppressant drugs. More
Biology of Breast Cancer is Changing
from RedOrbit
Research suggests that
lifestyle changes and screening have shifted the type of breast cancers women
are diagnosed with over the past couple of decades. It is now considered that
women will more likely have hormone-dependent, slow-growing tumors, a comparison
of tissue samples from the 1980s and 1990s shows. The British Journal of Cancer
reports that Scottish researchers also found improved survival over time. Over
40,000 women are diagnosed with breast cancer in the U.K. annually, and almost
200,000 in the U.S. More
Cell Injections Accelerate Fracture Healing
from Science Daily
Long bone fractures
heal faster after injections of bone-building cells. New research has shown that
osteoblast cells cultured from a patient's own bone marrow can be injected into
the fracture area and can speed the healing process. More
Scientists Identify Human Monoclonal Antibodies Effective Against
Bird, Seasonal Flu Viruses
from EurekAlert!
Researchers at the
Dana-Farber Cancer Institute, Burnham Institute for Medical Research and the
Centers for Disease Control and Prevention have reported the identification of
human monoclonal antibodies that neutralize an unprecedented range of influenza
A viruses, including avian influenza A virus, previous pandemic influenza
viruses, and some seasonal influenza viruses. These antibodies have the
potential for use in combination with other treatments to prevent or treat
certain types of avian and seasonal flu. The study will be published online on
Feb. 22 in Nature Structural and Molecular Biology. More
Reading DNA Base by Base
from Chemistry World
A technique to
electrically detect individual DNA bases cut from a single strand of DNA has
been developed by researchers in the UK. Hagan Bayley and his team from the
University of Oxford, working in conjunction with their spin-out company Oxford
Nanopore, say they hope the technology will lead to a simple and affordable new
DNA sequencing method. More
Toxicology Program Features Wide Range of Human Health and Environment
Topical Sessions
from EurekAlert! via Genetic Engineering &
Biotechnology News
Nearly 6,500 toxicologists from around the
world will be gathering in Baltimore, Md., March 15-19, to create an
unparalleled venue for discussion of a number of health and environmental topics
of concern to the public. The Society of Toxicology's 2009 Annual Meeting and
ToxExpo brings together thousands of scientists from universities, government,
and industry to showcase a year's worth of achievements in research and
education. More
Could
Genetics Improve Warfarin Dosing?
from the National Institute of
Health
In a large-scale study and an upcoming clinical trial,
scientists supported by the National Institutes of Health address one of the
trickiest issues in prescribing medicine — how to quickly optimize each
patient’s dosage of the common blood-thinning drug warfarin. One of the most
widely prescribed drugs in the world, warfarin is used to prevent dangerous
blood clots that can lead to heart attacks, strokes or even death. More
