Airline pilots, cabin crews have higher incidence of melanoma

2014-09-03
(Press-News.org) Bottom Line: Airline pilots and cabin crews appear to have twice the incidence of melanoma as the general population.

Author: Martina Sanlorenzo, M.D., of the University of California, San Francisco, and colleagues.

Background: Melanoma is a common cancer in the United States; in 2014, 76,100 people will be diagnosed with the skin cancer and 9,710 people will die. Several studies have suggested a higher incidence of melanoma in pilots and flight crew. Flight-based workers are thought to have a greater occupational hazard risk of melanoma because of increased altitude-related exposure to UV and cosmic radiation. While the risks of exposure to ionizing radiation for pilots and cabin crew are known and the levels regularly monitored, UV exposure is not a well-recognized occupational risk factor for the flight crew.

How the Study Was Conducted: The authors assessed the risk of melanoma in pilots and airline crew by reviewing medical literature. Their meta-analysis included 19 studies with more than 266,000 participants.

Results: The overall summary standardized incidence ratio (SIR) of melanoma for any flight-based occupation was 2.21, the summary SIR for pilots was 2.22 and 2.09 for cabin crew.

Discussion: "In this systematic review and meta-analysis including 19 studies and more than a quarter of a million participants, we found that the combined and separate SIRs for pilots and cabin crew were greater than the 2, indicating that pilots and air crew have twice the incidence of melanoma compared with the general population. … This has important implications for occupational health and protection of this population."

Obsessive compulsive disorder diagnosis linked to higher rates of schizophrenia

2014-09-03
Bottom Line: A diagnosis of obsessive-compulsive disorder (OCD) appears to be associated with higher rates of schizophrenia and schizophrenia spectrum disorders. Authors: Sandra M. Meier, Ph.D., of Aarhus University, Denmark, and colleagues. Background: OCD and schizophrenia are distinct and infrequently overlapping disorders. But some studies have suggested higher rates of co-existing illness with the two disorders in patients. How the Study Was Conducted: The authors assessed the potential relationship between the two disorders using data from Danish registers. ...

Genetic 'hotspot' linked to endometrial cancer aggressiveness

Genetic hotspot linked to endometrial cancer aggressiveness
2014-09-03
Parents of twins often tell them apart through subtle differences such as facial expression, moles, voice tone and gait. Similarly, physicians treating women with endometrial cancer must be able to distinguish between different versions of this disease form that, on the surface, appear the same. With endometrial cancer, the most common gynecological cancer in the western world and the fourth most prevalent in the U.S., it can literally be a matter of life and death. Mortality rates from this cancer have nearly tripled in the last 25 years and are thought to be attributed ...

Can sleep loss affect your brain size?

2014-09-03
MINNEAPOLIS – Sleep difficulties may be linked to faster rates of decline in brain volume, according to a study published in the September 3, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology. Sleep has been proposed to be "the brain's housekeeper", serving to repair and restore the brain. The study included 147 adults 20 and 84 years old. Researchers examined the link between sleep difficulties, such as having trouble falling asleep or staying asleep at night, and brain volume. All participants underwent two MRI brain scans, ...

Polyester clothes stink after exercise; cotton, not so much

2014-09-03
Polyester clothes smell worse than cotton, following intensive exercise by their wearers, because bacteria that cause odor grow better on polyester, according to research published ahead of print in the journal Applied and Environmental Microbiology. In the study, the investigators collected t-shirts from 26 healthy individuals following an intensive, hour-long bicycle spinning session, and incubated the shirts for 28 hours before having them inspected by a trained odor panel. The researchers also investigated the taxonomy of the bacteria on the shirts, and in the axillaries. ...

NASA's HS3 hurricane mission and Terra satellite take on Tropical Storm Dolly

NASAs HS3 hurricane mission and Terra satellite take on Tropical Storm Dolly
2014-09-03
NASA has Tropical Storm Dolly covered by satellite and the remotely piloted Global Hawk aircraft. Both captured data on Dolly before it made landfall in eastern Mexico. The MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Terra satellite took an image of Tropical Storms Norbert in the Eastern Pacific and Dolly in the Gulf of Mexico at 1:30 p.m. EDT on Sept. 2. The image showed Dolly is a much more organized storm than Norbert, and revealed Dolly's strongest, towering thunderstorms around the center of circulation. Norbert is close to the ...

Researchers discover new clues to determining the solar cycle

Researchers discover new clues to determining the solar cycle
2014-09-03
Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun's activity, known as solar maximum, is a time of numerous sunspots, punctuated with profound eruptions that send radiation and solar particles out into the far reaches of space. However, the timing of the solar cycle is far from precise. Since humans began regularly recording sunspots in the 17th century, the time between successive solar maxima has been as short as nine years, but as long as 14, making it hard to determine its cause. ...

NASA sees Tropical Storm Norbert affecting Mexico's west coast

NASA sees Tropical Storm Norbert affecting Mexicos west coast
2014-09-03
Tropical Storm Norbert has now triggered Tropical Storm Warnings for Mexico's West Coast, and NASA's Terra satellite showed how close it is to land. On Wednesday, September 3, the National Hurricane Center (NHC) issued a Tropical Storm Warning from La Paz to Santa Fe, Mexico. There is also a Tropical Storm Watch in effect from north of Santa Fe northward to Cabo San Lazaro, Mexico. he MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Terra satellite took an image of Tropical Storms Norbert in the Eastern Pacific and Dolly in the Gulf of ...

Climate change science aided by huge but 'invisible' efforts of amateurs

2014-09-03
Ithaca, N.Y.— Hundreds of thousands of volunteer data collectors are due for some thanks from scientists, according to a new paper that reveals the role of citizen science in studies of birds and climate change. Data collected by amateurs underpins up to 77 percent of the studies in this field, but that fact is largely invisible by the time the research appears in journals, according to a study published today in the open-access journal PLOS ONE: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0106508 "Our paper is a chance to say thank you to the ...

Forming consensus in social networks

2014-09-03
CORAL GABLES, Fla. (Sept. 3, 2014) -- Social networks have become a dominant force in society. Family, friends, peers, community leaders and media communicators are all part of people's social networks. Individuals within a network may have different opinions on important issues, but it's their collective actions that determine the path society takes. To understand the process through which we operate as a group, and to explain why we do what we do, researchers have developed a novel computational model and the corresponding conditions for reaching consensus in a wide ...

Leaky gut -- A source of non-AIDS complications in HIV-positive patients

2014-09-03
Human immunodeficiency virus (HIV) infection is no longer a fatal condition, thanks to newer medications inhibiting the retrovirus, but a puzzling phenomenon has surfaced among these patients — non-AIDS complications. Scientists at Case Western Reserve University School of Medicine have resolved the mystery with their discovery of the leaky gut as the offender. Bacterial products seep out of the colon, trigger inflammation throughout the body and set into motion the processes of cardiovascular, neurodegenerative, chronic kidney and metabolic diseases, and cancer. Their ...
