- TUESDAY, Aug. 19 (HealthDay News) — A new imaging system that
highlights cancerous tissue makes it easier for surgeons to detect and
remove tumors without harming surrounding healthy tissue, according to
U.S. researchers.

The fluorescence-assisted resection and exploration (FLARE)
system –which consists of a near-infrared (NIR) imaging system, a video
monitor and a computer — shows particular promise for [...]

- TUESDAY, Aug. 19 (HealthDay News) — Grapefruit juice, long known
to boost the absorption of certain medications, isn't the only juice that
doesn't mix well with drugs, according to the Canadian researcher who
first identified the ill effects of grapefruit juice.

Other common juices, including orange and apple, may limit the body's
absorption of drugs, compromising their effectiveness, [...]

- TUESDAY, Aug. 19 (HealthDay News) — Inexpensive ultrasound
imaging may be a simple way to help determine who's at high risk for a
heart attack or other cardiovascular issues, a new study says.

Researchers conducted ultrasound imaging on the carotid arteries — the
two vessels that supply blood to the head and neck — of 1,268 [...]

- TUESDAY, Aug. 19 (HealthDay News) — The use of silver-coated
endotracheal tubes reduced the risk of pneumonia among intensive-care
patients on ventilators, a U.S. study found.

Ventilator-associated pneumonia can lead to longer hospital stays,
increased costs, and infection with antibiotic-resistant bacteria.
Currently, no single prevention strategy eliminates ventilator-associated
pneumonia, according to background information in the study.

Previous laboratory and [...]

- TUESDAY, Aug. 19 (HealthDay News) — A majority of seniors who
visit the Medicare Web site find getting the information they need a
frustrating experience, University of Miami researchers report.

Whether trying to determine their eligibility for home health care or
which Medicare drug plan is best for them, most seniors found Medicare's
Web site difficult to use. [...]

- TUESDAY, Aug. 19 (HealthDay News) — A study to determine whether
folic acid and vitamin B supplements help the heart has been cut short,
because the pills weren't doing any good and might have even caused
participants harm.

“This confirms what a lot of recent studies have found — no benefit of
taking vitamin B supplements to [...]

- TUESDAY, Aug. 19 (HealthDay News) — The obesity epidemic in
America has gotten worse — not better — in the last year, despite public
service campaigns warning about the health risks posed by carrying too
much weight, a new report found.

Adult obesity rates increased in 37 states, while there were no
decreases in any states, according to [...]

- TUESDAY, Aug. 19 (HealthDay News) — A mathematical model to find
blood biomarkers that can help doctors estimate the size of cancer tumors
has been developed by researchers at Stanford University.

The team says its work may help guide development of new tests to
improve early detection of cancer. Currently, there's no reliable method
of using the results [...]

- TUESDAY, Aug. 19 (HealthDay News) — High levels of arsenic in
urine may be linked with a higher risk of developing type 2 diabetes,
researchers report.

The findings, published in the Aug. 20 issue of the Journal of the
American Medical Association, are the first to link low-level exposure
to arsenic with type 2 diabetes prevalence in the [...]

CHICAGO (Reuters) -
Arsenic, a naturally occurring poison
and carcinogen found in ground water, is strongly linked to
adult-onset diabetes, U.S. researchers said on Tuesday.
