Second-hand smoke implicated for adolescent hearing loss

Secondhand (SHS) smoke has received a significant amount of attention for harming health. Now a study shows adolescents exposed to SHS are at increased risk for hearing loss, in addition to other health issues that include respiratory ailments, behavior problems and low birth weight. 

The finding, published inthe July issue of Archives of Otolaryngology–Head and Neck Surgery, one of the JAMA/Archives journals, cites statistics that 60 percent of children are exposed to secondhand smoke in the United States.

How second hand smoke leads to hearing loss in youth The link is seen from recurrent ear infections, or otitis media. The chance of ear damage and sensorineural hearing loss (SNHL) increased with higher levels of exposure to secondhand smoke in adolescents studied.
The authors says hearing loss may occur from "suppression or modulation of the immune system" or from "impairment of the respiratory mucociliary apparatus" that would normally act as a defense against ba…

Stored blood for transfusion becomes less safe with aging, finds new study

Image
New research shows current methods of storing blood may be unsafe. Findings from scientists at Wake Forest University and the University of Pittsburgh School of Medicine found some complications associated with blood transfusion comes from the breakdown of red blood cells that happens during storage.


The finding means it may be necessary to find new ways to preserve blood for transfusion.


According to background information from the study, someone in the United States needs a blood transfusion every two seconds.


The finding, published in the journal Circulation, found nitric oxide (NO) interacts with stored red blood cells, breaking down blood flow. For transfusion recipients, vital tissues can be damaged from blood stored for long periods of time.


Higher rates of infection risk, kidney, lung or multi-organ failure and death have been observed among patients given transfusions from blood stored for longer periods of time, leading the researchers to try to understand why.

Study: Bigger forks stop diners from ‘pigging out’

When it comes to the battle of the bulge, new research shows simply using a bigger fork stopped restaurant diners from 'pigging out'. Using a bigger fork helped diners eat less in an experiment.


According a July 14. 2011 news release, putting a bigger bite of food on your fork leads to less eating from important visual cues that otherwise seemed to be overlooked by food consumers.

The finding, which appears in the Journal of Consumer Research, is an interesting note for women who may not find a big fork so delicate.
But for weight loss, a bigger fork gives visual cues that could help with setting goals.
The study authors, from University of Utah, Salt Lake City, write: "The fork size provided the diners with a means to observe their goal progress. The physiologicalfeedback of feeling full or the satiation signal comes with a time lag. In its absence diners focus on the visual cue of whether they are making any dent on the food on their plate to assess goal progress."
