African American women receive less breast reconstruction after mastectomy

55 percent less likely to have breast reconstruction regardless of type of hospital

2014-09-11
(Press-News.org) Dartmouth researchers have found that African American women are 55 percent less likely to receive breast reconstruction after mastectomy regardless of where they received their care. They report on their findings in "The influence of race/ethnicity and place of service on breast reconstruction for Medicare beneficiaries with mastectomy," recently published in SpringerPlus.

"We wanted to understand whether the racial disparity observed in breast reconstruction among women with breast cancer was related to where women received care, independent of race," said Tracy Onega, PhD, Associate Professor of Community & Family Medicine, Norris Cotton Cancer Center, and The Dartmouth Institute for Health Policy and Clinical Practice, The Geisel School of Medicine at Dartmouth. "This study fills an important gap in addressing whether racial disparities in breast reconstruction are due – at least in part - to disproportionate use of hospitals with services available."

Breast reconstruction after mastectomy is associated with better quality of life and other benefits—in fact insurance coverage for reconstruction is legislatively mandated. The study found that African American women were 55 percent less likely to receive breast reconstruction after mastectomy. Lower likelihoods of breast reconstruction for women of all races were observed for those attending hospitals that were: rural (67 percent less likely than urban), non-teaching (25 percent less likely than teaching), not part of cooperative oncology groups (32 percent less likely than coops), and performed fewer breast cancer surgeries (between 24-31 percent less likely than the highest quartile of volume). Although the effect of hospital type on breast reconstruction is significant, African American and Caucasian women did not differ significantly in their use of hospitals with these characteristics.

"The next step is to understand which factors contribute to the disparity," said Onega. "We want to understand whether these factors are economic (although all women studied were insured by Medicare), cultural, behavioral, etc. so that we can begin to develop targeted interventions for all women who would prefer to have reconstruction after mastectomy, to increase their quality of life and well-being."

Commensal bacteria help orchestrate immune response in lung

2014-09-11
Studies in mice demonstrate that signals from the bacteria that harmlessly—and often beneficially—inhabit the human gastrointestinal tract boost the immune system's ability to kill a major respiratory pathogen, Klebsiella pneumoniae, according to a paper published online ahead of print in the journal Infection and Immunity. The research is yet another example of how important these "commensal" bacteria are to human health and physiology, says Thomas B. Clarke, of Imperial College London, UK, the lone author of this paper. "Numerous studies have shown that changes ...

Researchers make scientific history with new cellular connection

2014-09-11
Researchers led by Dr. Helen McNeill at the Lunenfeld-Tanenbaum Research Institute have revealed an exciting and unusual biochemical connection. Their discovery has implications for diseases linked to mitochondria, which are the primary sources of energy production within our cells. Dr. McNeill's team has an international reputation for their work in understanding how cells become organized into tissues and how growth is regulated during development. The group focuses on mutations in the fat (ft) gene. The protein product of this gene, called 'Fat', acts at the cell membrane ...

Primary care doctors reluctant to provide genetics assessment in routine care

2014-09-11
Ann Arbor, Mich. — Primary care providers report many challenges to integrating genetics services into routine primary care, according to research published today in Genetics in Medicine. Medical genetics medicine has traditionally been used to identify and diagnose rare diseases, but in the last decade it has been increasingly helpful in determining patients at risk for genetically-based conditions who can benefit from preventive health care, says the study's senior author, Beth Tarini, M.D., M.S., F.A.A.P., assistant professor of pediatrics at the University of Michigan ...

Penn medicine study reveals profile of patients most likely to delay hospice enrollment

2014-09-11
One in six cancer patients enroll in hospice only during their last three days of life, according to a new study from a team from the Perelman School of Medicine at the University of Pennsylvania. Their findings, published online last month in the Journal of Clinical Oncology (JCO) also reveal a profile of patients who may be most at risk of these late admissions. "Waiting until the final days of life to begin hospice can shortchange patients and their families – skipping over many benefits of hospice care and limiting the opportunity to improve patients' quality of ...

Study maps 15 years of carbon dioxide emissions on Earth
2014-09-11
TEMPE, Ariz. – World leaders face multiple barriers in their efforts to reach agreement on greenhouse gas emission policies. And, according to Arizona State University researchers, without globally consistent, independent emissions assessments, climate agreements will remain burdened by errors, self-reporting, and the inability to verify emissions progress. Now, an international research team led by ASU scientists has developed a new approach to estimate CO2 emissions from burning fossil fuels — one that provides crucial information to policymakers. Called the "Fossil ...

Dartmouth research links genetic mutation and melanoma progression

2014-09-11
Dartmouth researchers have found that the genetic mutation BRAFV600E, frequently found in metastatic melanoma, not only secretes a protein that promotes the growth of melanoma tumor cells, but can also modify the network of normal cells around the tumor to support the disease's progression. Targeting this mutation with Vemurafenib reduces this interaction, and suggests possible new treatment options for melanoma therapy. They report on their findings in "BRAFV600E melanoma cells secrete factors that activate stromal fibroblasts and enhance tumourigenicity," which was recently ...

Imagine a balloon that could float without using any lighter-than-air gas. Instead, it could simply have all of its air sucked out while maintaining its filled shape. Such a vacuum balloon, which could help ease the world's current shortage of helium, can only be made if a new material existed that was strong enough to sustain the pressure generated by forcing out all that air while still being lightweight and flexible. Caltech materials scientist Julia Greer and her colleagues are on the path to developing such a material and many others that possess unheard-of combinations ...

Scientists report first semiaquatic dinosaur, Spinosaurus

2014-09-11
WASHINGTON (Sept. 11, 2014)—Scientists today unveiled what appears to be the first truly semiaquatic dinosaur, Spinosaurus aegyptiacus. New fossils of the massive Cretaceous-era predator reveal it adapted to life in the water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment. The fossils also indicate that Spinosaurus was the largest known predatory dinosaur to roam the Earth, measuring more than 9 feet longer than the world's largest Tyrannosaurus rex specimen. These findings, published ...

Malaria parasites sense and react to mosquito presence to increase transmission

Malaria parasites sense and react to mosquito presence to increase transmission
2014-09-11
Many pathogens are transmitted by insect bites. The abundance of vectors (as the transmitting insects are called) depends on seasonal and other environmental fluctuations. An article published on September 11thin PLOS Pathogens demonstrates that Plasmodium parasites react to mosquitoes biting their hosts, and that the parasite responses increase transmission to the mosquito vector. Sylvain Gandon, from the CNRS in Montpellier, France, and colleagues first studied the theoretical evolution of parasite evolution in a variable environment. Using a mathematical model, they ...

Evolutionary tools improve prospects for sustainable development
2014-09-11
Solving societal challenges in food security, emerging diseases and biodiversity loss will require evolutionary thinking in order to be effective in the long run. Inattention to this will only lead to greater challenges such as short-lived medicines and agricultural treatments, problems that may ultimately hinder sustainable development, argues a new study published online today in Science Express, led by University of California, Davis and the Center for Macroecology, Evolution and Climate at the University of Copenhagen. For the first time, scientists have reviewed ...
