Huntsman Cancer Institute research shows melanoma rates in Utah compared to
2021-04-08
(Press-News.org) SALT LAKE CITY - A letter published today by Huntsman Cancer Institute (HCI) at the University of Utah (U of U) in the New England Journal of Medicine reports that melanoma mortality among Utahns outpaced that of the rest of the United States during the period from 1975 to 2013. Melanoma death rates have been decreasing in recent years both in Utah and the United States, a trend likely attributable to new, more effective treatments, like immunotherapy. However, melanoma remains the deadliest type of skin cancer, and the incidence of melanoma diagnoses in Utahns is higher than in any other state.

The research was conducted in response to recent published data showing that for most of the 1990s and 2000s, melanoma mortality in the United States remained constant, while incidence increased six-fold. Increasing incidence without a corresponding increase in mortality suggests a potentially worrying trend of overdiagnosis--that is, when patients with benign conditions are incorrectly diagnosed as having cancer. In the case of melanoma, overdiagnosis may result from increased scrutiny, where repeated skin exams lead to increasing numbers of biopsies and a higher chance of finding a lesion that would not have been detected otherwise, and which might not be likely to progress to a harmful cancer.

Given Utah's status as the state with the highest incidence of melanoma, the HCI team set out to evaluate the melanoma diagnosis and death rate data in Utah. After review and analysis of data by biostatistician Kim Herget from the Utah Cancer Registry, a National Cancer Institute Survival, Epidemiology, and End Results (SEER) database, the researchers found that in contrast to the rest of the United States, melanoma mortality in Utah increased by 0.8% per year through the entire period from 1975 through 2013. While melanoma deaths in Utah are decreasing in recent years, Utah's melanoma death rate remains higher than that observed in the rest of the United States.

"Although we agree that overdiagnosis of melanoma is a growing problem, the sustained increase in melanoma mortality in Utah suggests that at least some fraction of the increasing incidence is real and cannot be attributed solely to overdiagnosis," said Doug Grossman, MD, PhD, who co-leads the HCI melanoma and skin cancer center at HCI and serves as professor of dermatology at the U of U. "Our research underscores an increased risk for Utahns, and so we must remain vigilant about melanoma. For doctors, this means regular conversations with patients about their skin health and family history. For patients, this means practicing sun-safe behaviors like diligent sunscreen use, wearing sun-protective clothing, and monitoring their skin at home on a monthly basis to reduce risk of skin cancer and optimize early detection."

The researchers anticipate future studies to determine whether this trend in Utahns is a result of increased ultraviolet exposure in a largely fair-skinned population living in a sunny, high-altitude climate or is associated with other environmental or genetic factors.

INFORMATION:

In addition to Grossman, the research was led by HCI epidemiologists Jennifer Doherty, PhD, MS, director of the Utah Cancer Registry and associate professor of population health sciences at the U of U, and Carol Sweeney, PhD, associate director of the Utah Cancer Registry and professor of internal medicine at the U of U. This research is supported by the National Cancer Institute including P30 CA042014, and National Institutes of Health, Department of Health and Human Services, under Contract No. HHSN261201800016I, and Huntsman Cancer Foundation.

Huntsman Cancer Institute (HCI) at the University of Utah is the official cancer center of Utah. The cancer campus includes a state-of-the-art cancer specialty hospital as well as two buildings dedicated to cancer research. HCI treats patients with all forms of cancer and is recognized among the best cancer hospitals in the country by U.S. News and World Report. As the only National Cancer Institute (NCI)-Designated Comprehensive Cancer Center in the Mountain West, HCI serves the largest geographic region in the country, drawing patients from Utah, Nevada, Idaho, Wyoming, and Montana. More genes for inherited cancers have been discovered at HCI than at any other cancer center in the world, including genes responsible for hereditary breast, ovarian, colon, head, and neck cancers, along with melanoma. HCI manages the Utah Population Database, the largest genetic database in the world, with information on more than 11 million people linked to genealogies, health records, and vital statistics. HCI was founded by Jon M. and Karen Huntsman.

New research shows that Mars did not dry up all at once
2021-04-08
LOS ALAMOS, N.M., April 8, 2021-While attention has been focused on the Perseverance rover that landed on Mars last month, its predecessor Curiosity continues to explore the base of Mount Sharp on the red planet and is still making discoveries. Research published today in the journal Geology shows that Mars had drier and wetter eras before drying up completely about 3 billion years ago. "A primary goal of the Curiosity mission was to study the transition between the habitable environment of the past, to the dry and cold climate that Mars has now. These rock layers recorded that change in great detail," said Roger Wiens, a coauthor on the paper and scientist at Los Alamos National Laboratory, ...

Violence and its effects on healthcare service, access, and strategies

Violence and its effects on healthcare service, access, and strategies
2021-04-08
PHILADELPHIA (April 8, 2021) - Many factors, including need, affect healthcare use. Strategies geared to enhancing the provision and access to healthcare must consider the various mechanisms that contribute to healthcare need and use. Until now, the mechanism of violence and its impact on both health and healthcare use has not been investigated. A new study from the University of Pennsylvania School of Nursing (Penn Nursing) is one of the first to examine the association between violence exposure and healthcare service utilization in Mexico. Results are published in the International Journal of Health Equity. Widespread violence in Mexico can impact health through various channels. The study ...

Can a 3D printed beetle model simulate the real thing?
2021-04-08
When it comes to choosing a partner, humans tend to be attracted by characteristics like personality and common interests. In contrast, insects tend to be a bit shallow, as they choose a mate based on appearance, and in some cases, smells. One example is the leaf beetle, which produces chemical pheromones that are on their cuticles, or the exterior surface of the beetle. They use these 'scents' to assess beetle sex and mating status (whether beetles are sexually mature or not). Kari Segraves, professor of biology in the College of Arts and Sciences, is interested in researching the chemical and visual signals that contribute to mate selection by these beetles. This work is part of a larger project focused on understanding how new species are formed. By definition, species are related ...

New method offers insights into tension-sensitivity of potassium channels

New method offers insights into tension-sensitivity of potassium channels
2021-04-08
Ion channels play an indispensable role in cellular physiology, and understanding the physical features that affect ion channel functions is a matter of considerable interest to biologists. Given that mechanosensitivity is an intrinsic feature of cells, the complex set of mechanical stresses acting on a cell at any time represents an important consideration in the field of cellular physiology. In fact, stretching forces created by mechanical stress are sometimes necessary to activate ion channels. As Professor Masayuki Iwamoto and Professor Shigetoshi Oiki of the University of Fukui ...

The tuberculosis pathogen releases its toxin by a novel protein transport system

The tuberculosis pathogen releases its toxin by a novel protein transport system
2021-04-08
BIRMINGHAM, Ala. - Six years ago, Michael Niederweis, Ph.D., described the first toxin ever found for the deadly pathogen Mycobacterium tuberculosis. This toxin, tuberculosis necrotizing toxin, or TNT, became the founding member of a novel class of previously unrecognized toxins present in more than 600 bacterial and fungal species, as determined by protein sequence similarity. The toxin is released as M. tuberculosis bacteria survive and grow inside their human macrophage host, killing the macrophage and allowing the escape and spread of the bacteria. For 132 years, ...

Seeing quadruple

Seeing quadruple
2021-04-08
With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic "lens" and split into four similar images. Quasars are extremely luminous cores of distant galaxies that are powered by supermassive black holes. Over the past four decades, astronomers had found about 50 of these "quadruply imaged quasars," or quads for short, which occur when the gravity of a massive galaxy that happens to sit in front of a quasar splits its single image into four. The latest study, which spanned only a year and a half, increases the number of known quads by about 25 percent and demonstrates the power of machine learning to assist ...

Dogs act jealously even when they don't see their rival

2021-04-08
Past surveys have shown that more than 80% of dog owners report observing jealous behaviors from their dogs--vocalizations, agitated behavior, pulling on a leash--when they give attention to other dogs. New research published in the journal Psychological Science supports these observations and finds that dogs also exhibit jealous behaviors when they merely imagine that their owner is interacting with a potential rival, in this case, a highly realistic artificial dog. "Research has supported what many dog owners firmly believe--dogs exhibit jealous behavior when their human companion interacts with a potential rival," said Amalia Bastos with ...

2021-04-08
Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn't know how they performed this feat. Now, Rutgers scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study, published in the END ...

Solar and wind power could mitigate conflict in northeast Africa

Solar and wind power could mitigate conflict in northeast Africa
2021-04-08
A new study shows that several disagreements between Ethiopia, Sudan and Egypt around Africa's largest hydropower plant, the new Grand Ethiopian Renaissance Dam (GERD), could be alleviated by massively expanding solar and wind power across the region. Adapting GERD operation to support grid integration of solar and wind power would provide tangible energy and water benefits to all involved countries, creating regional win-win situations. "Our results call for integrated hydro-solar-wind planning to be taken up in the GERD negotiations," says Sebastian Sterl, energy ...

Regional habitat differences identified for threatened piping plovers on Atlantic coast
2021-04-08
Piping plovers, charismatic shorebirds that nest and feed on many Atlantic Coast beaches, rely on different kinds of coastal habitats in different regions along the Atlantic Coast, according to a new study by the U.S. Geological Survey and U.S. Fish and Wildlife Service. The Atlantic Coast and Northern Great Plains populations of the piping plover were listed as federally threatened in 1985. The Atlantic coast population is managed in three regional recovery units, or regions: New England, which includes Massachusetts and Rhode Island; Mid-Atlantic, which includes New ...
