Large-scale study shows dramatic decline in mortality rates for ARDS
2014-10-21
(Press-News.org) (Austin, Texas) October 21, 2014 – The largest study to date of mortality trends in patients with acute respiratory distress syndrome (ARDS) shows that the rate of mortality dropped significantly over a 16-year period. Advances in critical care medicine are seen as a direct cause of the decline. The study abstract was released today in an online supplement of the of the journal CHEST and will be presented at CHEST 2014, the annual meeting of the American College of Chest Physicians in Austin, Texas held October 25-30.
Researchers at Rutgers Robert Wood Johnson Medical School, Staten Island University Hospital, the University of Pittsburgh Medical Center, and Government Medical College obtained data from the National Inpatient Sample (NIS) database, the largest inpatient health-care database in the United States, encompassing data from approximately 8 million hospital stays per year. Out of this database, they were able to identify over 174,000 patients who had ARDS.
The study showed that there was a striking decrease in mortality rates, from 46.8% in 1996 to 32.2% in 2011, a 14.6% reduction. Surprisingly, from the years 2000 to 2005 alone there was an 8.9% absolute reduction in mortality rates.
According to Jared Radbel, MD, "While we cannot prove causation for the decreased mortality, we believe that collaborative advances in critical care medicine contributed to the overall decline. We assert that the sudden and sharp decrease in mortality from 2000-2005 can be attributed to the practice of low tidal volume ventilation."

(Austin, Texas) October 21, 2014 – Patients who use a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea (OSA) often believe that it makes them less sexually attractive, according to researchers at Rosalind Franklin University. A new study abstract released today in an online supplement of the journal CHEST, to be presented at CHEST 2014, the annual meeting of the American College of Chest Physicians in Austin, Texas, shows that they do not need to worry.

Alpine goats appear to be shrinking in size as they react to changes in climate, according to new research from Durham University.
The researchers studied the impacts of changes in temperature on the body size of Alpine Chamois, a species of mountain goat, over the past 30 years.
To their surprise, they discovered that young Chamois now weigh about 25 per cent less than animals of the same age in the 1980s.
In recent years, decreases in body size have been identified in a variety of animal species, and have frequently been linked to the changing climate.

(Austin, Texas) October 21, 2014 – A new study shows that patients with stage I to stage III non-small cell lung cancer have different metabolite profiles in their blood than those of patients who are at risk but do not have lung cancer. The study abstract was released today in an online supplement of the journal CHEST and will be presented at CHEST 2014, the annual meeting of the American College of Chest Physicians in Austin, Texas, on October 29.

The way in which male moths locate females flying hundreds of meters away has long been a mystery to scientists.
Researchers know the moths use pheromones to locate their mates. Yet when these chemical odors are widely dispersed in a windy, turbulent atmosphere, the insects still manage to fly in the right direction over hundreds of meters with only random puffs of their mates' pheromones spaced tens of seconds apart to guide them.
"The male moths are flying toward females integrating all of this information along the way and somehow getting to them," said Massimo Vergassola, ...

An international team of physicists has measured a subtle characteristic in the polarization of the cosmic microwave background radiation that will allow them to map the large-scale structure of the universe, determine the masses of neutrinos and perhaps uncover some of the mysteries of dark matter and dark energy.
In a paper published this week in the Astrophysical Journal, the POLARBEAR consortium, led by University of California, Berkeley, physicist Adrian Lee, describes the first successful isolation of a "B-mode" produced by gravitational lensing in the polarization ...

CORVALLIS, Ore. – Children who show poor decision-making skills at age 10 or 11 may be more likely to experience interpersonal and behavioral difficulties that have the potential to lead to high-risk health behavior in their teen years, according to a new study from Oregon State University psychology professor.
"These findings suggest that less-refined decision skills early in life could potentially be a harbinger for problem behavior in the future," said Joshua Weller, an assistant professor in the School of Psychological Science in OSU's College of Liberal Arts.

Boulder, CO, USA — The last ten years have been a remarkable time for great earthquakes. Since December 2004 there have been no less than 18 quakes of Mw8.0 or greater – a rate of more than twice that seen from 1900 to mid-2004. Hundreds of thousands of lives have been lost and massive damage has resulted from these great earthquakes. But as devastating as such events can be, these recent great quakes have come with a silver lining: They coincide with unprecedented advances in technological and scientific capacity for learning from them.
"We previously had ...

Even though they are not hungry, children as young as three will find high-energy treats too tempting to refuse, new QUT research has found.
In a study of three and four year olds, 100 per cent of children opted for a sweet or savory snack despite eating a filling healthy lunch only 15 minutes prior.
Nutrition researcher Holly Harris, from QUT's Institute of Health and Biomedical Innovation, said the results highlighted the health risks for children frequently confronted with an abundance of energy-dense, high-calorie foods.

Recreational fishermen prize large trophy fish. Commercial fishing gear targets big fish. After all, larger fish feed the egos of humans as well as their bellies.
A new compilation of research from around the world now shows that big, old, fat, fertile, female fish – known as BOFFFFs to scientists – are essential for ensuring that fishery stocks remain sustainable.
"Information on many different kinds of freshwater and marine fish tell the same story," says lead author Dr. Mark Hixon of the University of Hawai'i at Mānoa. "The loss of big fish decreases ...
