A new study from the American Cancer Society finds recent declines in melanoma mortality rates in non-Hispanic Whites in the U.S. mainly reflect declines in those with the highest level of education, and reveals a widening disparity in melanoma mortality rates by education. The authors say the findings call for early detection strategies to effectively target high-risk, low-educated, non-Hispanic White individuals. The study is published Online First by Archives of Dermatology.
Since the early 1990s, overall melanoma mortality rates among Non-Hispanic Whites (ages 25 to 64 years) have been declining in men and women. But it has not been known whether these death rates might differ according to socioeconomic status (SES).
To study whether melanoma death rate trends might differ according to SES, researchers led by Vilma Cokkinides, Ph. D, reviewed death certificates from 26 states, representing approximately 45 percent of the U.S. population. They found melanoma mortality declined about ten percent between over the latest ten-year span (1993-97 to 2003-07) in both men (RR= 0.916, 95% C.I.= 0.878, 0.954) and women (RR = 0.907, 95% C.I.= 0.857, 0.957).
However, declines occurred only among those with at least 13 years of education or more, irrespective of sex. In fact, there were actually non-significant increases among the least educated individuals. As a result, the educational gap in melanoma mortality rates widened by 51.7% in men and by 35.7% in women between the two time periods (1993-97 and 2003-07).
"To our knowledge, this is the first study to document this education gap in melanoma mortality trends among Non-Hispanic Whites in the U.S.," said Dr. Cokkinides. "The reasons for the widening of the educational gap in mortality rates are not yet understood, but we do know the cornerstone of melanoma control is recognizing the signs of melanoma early. Lower socioeconomic status is associated with suboptimal knowledge and awareness of melanoma, inadequate health insurance, and lower rates of skin self-examination or physician screening."
The authors conclude recent declines in melanoma mortality are largely confined to more educated groups, and that an increasingly disproportionate burden of fatal melanoma among low SES populations calls for more vigilant primary and secondary prevention education campaigns directed to high-risk, low SES individuals and the physicians that care for them.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
