As a result, the highest burden of CRC mortality shifted from the Northeast in the early 1990s to the southern states along the Appalachian corridor in the mid 2000s. The decrease in CRC mortality rates by state correlated strongly with uptake of screening.
The study appears in Cancer Epidemiology Biomarkers and Prevention, and says improving screening rates through state-specific initiatives and/or expansion of the Colorectal Cancer Control Program of the Centers for Disease Control and Prevention to the Appalachian region and certain southern states could lessen the disproportionately high burden of CRC in these states.
Colorectal cancer mortality rates have been decreasing for many decades in the United States, with the decrease accelerating in the most recent time period. The extent to which this decrease varies across states and its influence on the geographic patterns of rates was previously unknown. To investigate, researchers led by American Cancer Society epidemiologist Ahmedin Jemal, Ph.D., analyzed trends in age-standardized CRC death rates for each state from 1990-2007. They found CRC mortality rates significantly decreased in all states except Mississippi between 1990-2007 based on the joinpoint model. The decrease in death rates between 1990-1994 and 2003-2007 ranged from 9% in Alabama to >33% in Massachusetts, Rhode Island, New York, and Alaska. Mississippi and Wyoming showed no significant decrease. Generally, the northeastern states showed the largest decreases, while southern states showed the smallest decreases. The highest CRC mortality rates shifted from the northeastern states during 1990-1994 to the southern states along the Appalachian corridor during 2003-2007. The decrease in CRC mortality rates by state correlated strongly with uptake of screening.
The authors conclude that progress in CRC mortality varies across states, with the Northeast showing the most progress and the South showing the least progress, and that the findings highlight the need for wider dissemination of CRC screening.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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...
