Study: More ‘Masculine’ and ‘Feminine’ Youth at Higher Risk for Cancer-risk Behaviors
The most “feminine” girls and the most “masculine” boys are also the most likely to engage in behaviors that pose cancer risks, according to a new study in the Journal of Adolescent Health. Researchers at the Harvard School of Public Health (HSPH) analyzed data on 9,354 adolescents in the ongoing Growing Up Today Study, finding that cancer-risk behaviors such as tobacco use, indoor tanning and physical inactivity were significantly more common in adolescents who more closely adhered to the traditional societal norms of masculinity and femininity. "Our findings indicate that socially constructed ideas of masculinity and femininity heavily influence teens' behaviors and put them at increased risk for cancer,” said lead author Andrea Roberts, research associate in the Department of Social and Behavioral Sciences at HSPH. “Though there is nothing inherently masculine about chewing tobacco, or inherently feminine about using a tanning booth, these industries have convinced some teens that these behaviors are a way to express their masculinity or femininity."

Study: Casual Marijuana Use Can Cause Dangerous Changes in Youths’ Brains
Casual marijuana use in young people can lead to potentially harmful changes in the brain, according to a new study in the Journal of Neuroscience. Researchers from Northwestern University's medical school, Massachusetts General Hospital and Harvard Medical School determined that casual marijuana smoking—defined as one to seven joints per week—could lead to changes to the nucleus accumbens and the nucleus amygdale, which help regulate emotion and motivation. "What we're seeing is changes in people who are 18 to 25 in core brain regions that you never, ever want to fool around with," said co-senior study author Hans Beiter, PhD, professor of psychiatry and behavioral sciences at Northwestern University, according to Reuters, adding, "Our hypothesis from this early work is that these changes may be an early sign of what later becomes amotivation, where people aren't focused on their goals.” Read more on substance abuse.
CDC: ‘Herd Immunity’ Helped Reduce H1N1 Flu Strain’s Impact This Season
While the H1N1 influenza strain was the predominant strain in the United States this past flu season, prior widespread exposure and its inclusion in the current flu vaccine meant it did not have nearly the impact it did in 2009, according to the U.S. Centers for Disease Control and Prevention (CDC). According to Michael Jhung, MD, a medical officer in the CDC’s influenza division, an overall “herd immunity” helped stop this season from turning into the worldwide pandemic seen in 2009. "This year, not only do we have a vaccine that works well, but millions of people have already been exposed to the H1N1 virus," he said, according to HealthDay. The flu strain also hit differently this season, peaking earlier, although once again younger adults were affected more than the elderly. Read more on the flu.
Study: Fertility Drugs Not Tied to Increased Risk of Breast Cancer
Fertility drugs are not linked to an increased risk of breast cancer, according to a new long-term study in the journal Cancer Epidemiology, Biomarkers & Prevention. Researchers analyzed records for 9,892 U.S. women who were followed for 30 years after having been evaluated for infertility between 1965 and 1988, finding that about 38 percent of them were exposed to the fertility drug clomiphene and about 10 percent were exposed to drugs known as gonadotropins. There were 749 breast cancers diagnosed during the three decades, but women who were exposed to either drug were just as likely as the women who hadn’t been exposed to fertility drugs to develop breast cancer. The study did note an increased risk of breast cancer for the small group of women exposed to the highest doses of clomiphene. "It's reassuring that if women desire pregnancy and unfortunately have infertility that they can undergo treatment without modification of their overall risk for cancer later," said Kurt Barnhart, MD, president of the Society for Reproductive Endocrinology and Infertility, to Reuters Health. He was not involved in the study. Read more on cancer.
Study: CDC’s Salt Recommendations Are Too Low
The U.S. Centers for Disease Control and Prevention’s (CDC) salt guidelines are too low, according to a new study in the American Journal of Hypertension. Researchers reviewed 25 previous studies, concluding that both too much and too little salt can be harmful. They concluded that the safest intake range was between 2,645 and 4,945 mg of salt a day, although the CDC recommends less than 2,300 mg of salt per day for healthy people under age 50, and less than 1,500 mg per day for most people over age 50. "For most people, there is no reason to change their dietary habits concerning salt, as most people eat what appears to be the safest amount," said review author Niels Graudal, MD, a senior consultant at Copenhagen University Hospital in Denmark, according to HealthDay.

HUD to Provide Disaster Assistance to Washington State Mudslide Victims
Having officially been given a major disaster declaration yesterday, Snohomish County and the Sauk-Suiattle, Stillaguamish and Tulalip Indian Reservations in Washington state will now received federal disaster assistance from the U.S. Department of Housing and Urban Development (HUD) to help recover from the flooding and mudslides that began on March 22. Among the assistance:
- Offering the State of Washington and other entitlement communities the ability to re-allocate existing federal resources toward disaster relief
- Granting immediate foreclosure relief
- Making mortgage insurance available
- Making insurance available for both mortgages and home rehabilitation
- Offering Section 108 loan guarantee assistance
- Information on housing providers and HUD programs
"Families who may have been forced from their homes need to know that help is available to begin the rebuilding process,” said HUD Secretary Shaun Donovan in a release. "Whether it's foreclosure relief for FHA-insured families or helping these counties to recover, HUD stands ready to help in any way we can." Read more on disasters.
CDC: 1 in 68 U.S. Children on Autism Spectrum
The U.S. Centers for Disease Control and Prevention (CDC) has significantly increased its estimates of the number of U.S. children with an autism spectrum disorder (ASD). According to a new surveillance summary report, approximately 1 in 68 children—or 14.7 per 1,000 eight-year-olds—are on the spectrum. The new estimate is about 30 percent higher than previous CDC estimates. The report also found that ASD continue to be five times more common among boys than girls; more common among white children than Black of Hispanic children; and that most children are still not diagnosed until after age 4, despite the fact that ASD can be diagnosed as early as age 2. “The number of children identified with autism continues to increase and the characteristics of these children have changed over time,” said Coleen A. Boyle, PhD, MS, director of CDC’s National Center on Birth Defects and Developmental Disabilities, in a release. “While progress has been made, there is an urgent need to continue the search for answers and provide help now for people living with autism.” Read more on pediatrics.
New Cancer Cases Dropped Slightly from 2009 to 2010
Rates of new cancer cases dropped slightly for both men and women in the United States from 2009 to 2010, according to the new U.S. Centers for Disease Control and Prevention report, Invasive Cancer Incidence—United States, 2010. The report saw the incidence rate drop to 446 per 100,000 persons from 459 per 100,000 persons. Rates varied by state, from a high of 511 to a low of 380. The rate was higher for men than it was for women, with the highest rate of all among black Americans. Read more on cancer.
HHS Releases New Security Risk Assessment Tool for Small-to-Medium-Sized Health Care Organizations
The U.S. Department of Health and Human Services (HHS) has released a new security risk assessment (SRA) tool to help health care providers in small-to-medium sized offices conduct risk assessments of their organizations. A collaborative effort of the HHS Office of the National Coordinator for Health Information Technology (ONC) and Office for Civil Rights (OCR), the tool enables the organizations to conduct and document a thorough risk assessment at their own pace by allowing them to assess the information security risks under the Health Insurance Portability and Accountability Act (HIPAA) Security Rule. The SRA tool’s website contains a User Guide and Tutorial video to help providers begin using the tool. Videos on risk analysis and contingency planning are available at the website to provide further context. The tool is available for both Windows and operating systems and iOS iPads.

Poison Prevention Week 2014
March 16-24 is Poison Prevention Week this year, and an important opportunity to remind health officials and consumers about the resources provided by the National Poison Prevention Program and Hotline (1-800-222-1222). The National Poison Control Program is a program of the Health Resource Services Administration (HRSA). Programs include:
- Poison centers serving all states, Puerto Rico, the District of Columbia, Guam, the Federated States of Micronesia and American Samoa.
- A single, national toll-free number (1-800-222-1222) that connects callers with the poison center serving their area.
- A nationwide media campaign to educate the public and health care providers about poison prevention, poison center services and the 1-800 number.
- Programs to support the enhancement and improvement of poison education, prevention and treatment.
- Partnership development with other federal agencies and national organizations to advance poison prevention awareness.
- Development of uniform patient management guidelines so that poison centers can provide uniform treatment recommendations.
- Improvement of data collection systems and toxic exposure surveillance for enhanced capability to capture national poisoning data.
- Multilingual interpreter service in 161 languages to anyone who calls the 1-800 number.
Colon Cancer Incidence Rates Decreasing Steeply in Older Americans
Colon cancer incidence rates have dropped 30 percent in the United States in the last 10 years among adults 50 and older because of the widespread use of colonoscopies, according to a new study in CA: A Cancer Journal for Clinicians. The largest decrease has been in people over age 65. Colonoscopy use has almost tripled among adults ages 50-75, from 19 percent in 2000 to 55 percent in 2010. The study relied on data from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program and the U.S. Centers for Disease Control and Prevention's National Program of Cancer Registries.
The "larger declines among Medicare-eligible seniors likely reflect higher rates of screening because of universal insurance coverage," according to the study authors. Mortality rates from colon cancer have also declined most rapidly within the past decade. From 2001 to 2010, death rates from colon cancer decreased by approximately 3 percent per year in both men and women, compared with declines of approximately 2 percent per year during the 1990s. The data is being released as the U.S. Department of Health and Human Services launches a nationwide effort to increase colorectal cancer screening rates to 80 percent by 2018. Read more on cancer.
DOT Proposed Rules on Electronic Log Books for Large and Bus Drivers to Help Reduce Fatalities and Injuries
The U.S. Department of Transportation (DOT) has announced a proposal to require interstate commercial truck and bus companies to use Electronic Logging Devices (ELDs) in their vehicles to improve compliance with the safety rules that govern the number of hours a driver can work. According to DOT, the proposed rule will ultimately reduce hours-of-service violations by making it more difficult for drivers to misrepresent their time on logbooks and—significantly—help reduce crashes by fatigued drivers and prevent approximately 20 fatalities and 434 injuries each year, for an annual safety benefit of $394.8 million. Impaired driving, including fatigue, was a factor in more than 12 percent of the 129,120 total crashes that involved large trucks or buses in 2012. Read more on injury prevention.
New Report on US Cancer Care Finds Significant Cost and Quality Challenges
A new report from the American Association of Clinical Oncology (ASCO) finds that several factors including an aging population and poor lifestyle habits in the United States have resulted in an increase in annual cancer cases at the same time many smaller oncology practices are closing because of financial pressures. "We're facing a collection of challenges, each one of which could keep cancer treatment advances out of reach for some individuals," said ASCO President Clifford A. Hudis, MD.
ASCO’s recommendations include:
- Support for novel cancer care delivery efforts.
- Development of new healthcare delivery and payment models to help ensure the viability of small community practices while encouraging high-quality care.
- Support for quality initiatives that will speed up dissemination of cancer treatment breakthroughs and changes.

Spring Break Highlights Dangers of Binge Drinking
The average male Spring Breaker reports drinking 18 alcoholic drinks per day during the week-long festivity, while the average female reports up to 10 drinks, according to the American College of Health. Five or more drinks within two hours qualify as “binge drinking” for men and four or more qualifies for women. Each year 1,825 college students ages 18-24 die from alcohol-related unintentional injuries, with alcohol poisoning among the biggest causes. Signs of alcohol poisoning include irregular breathing, vomiting, confusion and unconsciousness, and should be met with an immediate trip to the emergency room.
Among the other unintentional injuries:
- Assault — More than 690,000 students between the ages of 18 and 24 are assaulted by another student who has been drinking.
- Sexual Abuse — More than 97,000 students between the ages of 18 and 24 are victims of alcohol-related sexual assault or date rape.
- Injury — 599,000 students between the ages of 18 and 24 receive unintentional injuries while under the influence of alcohol.

Mass Analysis Confirms Link Between Bullying, Suicidal Thoughts
A new review of 43 previous studies seems to confirm the link between bullying and an increase in suicidal thoughts, with cyber bullying linked the most strongly. The study appears in JAMA Pediatrics and included data on approximately 350,000 youths. Approximately half of students in grades 4-12 report being bullied within the previous month, with one-third saying they were bullies themselves. While the new analysis does not demonstrate causation, it does indicate a more complex connection, perhaps even showing that kids with suicidal thoughts in the first place are more likely to be bullied.

CDC: Reducing High-risk Antibiotic Prescriptions Could Also Reduce Deadly Infections
The most recent Vital Signs report from the U.S. Centers for Disease Control and Prevention (CDC) finds that if prescriptions of high-risk antibiotics in hospitals were reduced by just 30 percent, then there could be as many as 26 fewer cases of deadly diarrhea infections with Clostridium difficile. “Improving antibiotic prescribing can save today’s patients from deadly infections and protect lifesaving antibiotics for tomorrow’s patients,” said CDC Director Tom Frieden, MD, MPH. “Health care facilities are an important part of the solution to drug resistance and every hospital in the country should have a strong antibiotic stewardship program.” As part of its ongoing efforts to improve antibiotic prescribing, the CDC has release a checklist of seven core elements for hospitals:
- Leadership commitment: Dedicate the necessary human, financial, and IT resources.
- Accountability: Appoint a single leader responsible for program outcomes. Physicians have proven successful in this role.
- Drug expertise: Appoint a single pharmacist leader to support improved prescribing.
- Act: Take at least one prescribing improvement action, such as requiring reassessment of prescriptions within 48 hours to check drug choice, dose, and duration.
- Track: Monitor prescribing and antibiotic resistance patterns.
- Report: Regularly report prescribing and resistance information to clinicians.
- Educate: Offer education about antibiotic resistance and improving prescribing practices.

Poorer Women Most Likely to Be Caught in ‘Vicious’ Caregiving, Financial Well-being Cycle
Low-income women are at increased risk of finding themselves caught in a “vicious cycle” of parental caregiving and financial well-being, according to a new study in The Journals of Gerontology. While women of better financial means can afford additional caregiver assistance and better health care for aging parents, poorer women lack those options. "People who had less household income and less financial resources were more likely to take care of their parents so there is this cycle that they cannot get out of—they are poor, then taking care of parents, then being poor and taking care of their parents—there's this kind of cycle," said lead author Yeonjung Lee, a researcher and professor at the Faculty of Social Work at the University of Calgary in Alberta, Canada, according to Reuters.

Young Skin Cancer Survivors at Heightened Risk for Other Cancers
Younger skin cancer survivors are at increased risk for additional cancer types later in life, according to a new study in the journal Cancer Epidemiology, Biomarkers & Prevention. A review of data of more than 500,000 people with a history of nonmelanoma skin cancer found that while all age groups were at heightened risk for melanoma and other types of cancers, the increase was especially significant for people under the age of 25, who were 23 times more likely to develop cancer than people who had never had nonmelanoma cancer. The risk was 3.5 times higher for nonmelanoma survivors ages 25-44, 1.74 times higher for those ages 45-59 and 1.32 times higher for those older than 60. The types of cancer they are at risk for include melanoma skin cancer, and cancers of the breast, colon, bladder, liver, lung, brain, prostate, stomach and pancreas. Read more on cancer.
Several leading cancer organizations recently formed a think tank to address health disparities in cancer research with the goal of improving treatment access and outcomes for underserved populations. “Closing the inequality gap will not happen easily, and won’t get done if any of us goes it alone," said Otis W. Brawley, MD, chief medical officer of the American Cancer Society (ACS), one of four groups involved, in addition to the American Association for Cancer Research (AACR); the American Society of Clinical Oncology (ASCO); and the National Cancer Institute (NCI), a branch of the National Institutes of Health (NIH).
“Cancer mortality rates are decreasing for most minorities, but absolute death rates continue to be higher," said NCI Deputy Director Doug Lowy, MD. Lowy adds that it’s important to understand the sources of the disparities in order to reduce them.
The goal of the collaboration is to address the fact that that some racial and ethnic minorities in the United States are more likely to develop cancer, less likely to access high-quality cancer care and more likely to die from cancer when compared to others and to whites. For example, the death rate for cancer among African-American males is 33 percent higher than among white males, and the rate for African-American females is 16 percent higher than it is for white females.
“We must move from describing the problems to more quickly identifying and implementing solutions to address the racial and economic-based disparities that continue to affect many cancer patients and families in the United States,” said ASCO president Clifford A. Hudis, MD.
NewPublicHealth recently spoke with Hudis about the new collaboration.
NewPublicHealth: What key issues help explain—and then overcome—differences in cancer incidence and severity among different populations?
Clifford A. Hudis: We can’t completely disentangle environmental factors, which include nutrition, access to care, general health behaviors, exercise and education, which relates to behaviors such as tobacco use. And of course underlying that is the socioeconomic status. But there also is a burgeoning understanding of the role of genetic variations that may be clustered in various populations and may influence things such as drug metabolism and diseases.
Study: Increasing Young Men’s Knowledge of Emergency Contraception Could Increase Access, Use
Increasing young men’s knowledge of emergency contraception could increase access to the drug and help prevent unwanted pregnancies, according to a new study in Journal of Family Planning and Reproductive Health Care. Emergency contraception, commonly known as "the morning after pill," prevents pregnancy after unprotected sex or when other methods of contraception fail. Nine U.S. states allow pharmacists to dispense emergency contraception without a prescription under certain conditions. The study gauged the knowledge of 101 males and 97 females ages 18 to in 2008 and 2009. "About half of the women understood basic facts about emergency contraception, how you get it, how you use it, and the fact that male partners were also able to buy it over-the-counter for their female partners," said Sheree Schrager, a member of the study team and a researcher at Children's Hospital Los Angeles, California. “But young men had significantly lower knowledge then the young women did, and this is an opportunity for providers to reach out to young men in the hopes of reaching more young women to use emergency contraception.” According to the researchers, unplanned pregnancies are more common in poor communities, where there are also greater health and economic consequences.

U.S., Global Partners to Joint in Prevention, Detection and Response to Infectious Disease
The United States has joined with 26 countries and other global partners to, over the next five years, work to prevent, detect and effectively respond to naturally occurring, accidental and intentional infectious disease threats. Additional partners in the Global Health Security Agenda include the World Health Organization (WHO), the Food and Agriculture Organization (FAO) and the World Organization for Animal Health (OIE). “While we have made great progress in fighting and treating diseases, biological threats can emerge anywhere, travel quickly, and take lives,” said Lisa Monaco, Assistant to the President for Homeland Security and Counterterrorism. “The recent outbreaks of H7N9 influenza and Middle East Respiratory Syndrome are reminders of the need to step up our efforts as a global community. The Global Health Security Agenda is about accelerating progress toward a world safe and secure from infectious disease threats.” The U.S. Centers for Disease Control and Prevention (CDC) has pledged $40 million in FY 2014 to advancing Global Health Security Agenda objectives, and its FY 2015 budget will include an additional $45 million to prevent avoidable catastrophes, detect threats early and mobilize effective responses to contain outbreaks.

CDC: States with Indoor Tanning Laws See Far Less Use by Female High School Students
States with indoor tanning laws—especially those requiring parental permission or setting age restrictions—see lower rates of indoor tanning by female high school students, according to a new study in the American Journal of Public Health. The study was conducted by the U.S. Centers for Disease Control and Prevention. Studies have connected the increased exposure to ultraviolet radiation from indoor tanning to increased risk of melanoma; each year the United States sees 60,000 new melanoma diagnoses and approximately 3.5 million treatments for nonmelanoma skin cancer. The study determined that the odds of female students engaging in indoor tanning in states with any indoor tanning laws were 30 percent less than those in states without such laws, and that the odds in states with systems access, parental permission and age restriction laws were 42 percent less than those in states without any laws. “State indoor tanning laws, especially age restrictions, may be effective in reducing indoor tanning among our nation’s youth,” said Gery Guy, PhD, health economist and the study’s lead author. “We need to address the harms of indoor tanning, especially among children. Indoor tanning laws can be part of a comprehensive effort to prevent skin cancers and change social norms around tanned skin.” Read more on cancer.

American Society of Clinical Oncology Weighs in on Mammography
In response to a study published this week in the British Medical Journal which called into question the benefit of mammography, the American Society of Clinical Oncology (ASCO) issued a statement today saying that because mammography is similar to many other tests that can detect a condition that may never cause harm, the benefits of screening are likely to be greater for women who are at increased risk of developing breast cancer based on factors such as age and family history, than for women at average risk. It also stated no single study should be used to change screening policy and that all women should be encouraged to speak with their doctors about their personal risk for breast cancer, as well as the potential benefits and harms of mammography screening. ASCO and other cancer advocacy and women’s health groups have announced that they will be monitoring additional mammography studies now being conducted, and the American Cancer Society is expected to release new mammography recommendations later this year.

NHTSA Announces New Mandatory Label to Help Owners Instantly Identify Recall Mailings
The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) today announced that starting February 18, all manufacturers must use a distinctive label on the agency’s required mailings that notify owners of recalled vehicles or equipment.
The requirement was introduced to help owners instantly distinguish important recall notices arriving in their mailboxes from other mail and hopefully avoid mistakenly discarding the safety notices. NHTSA has also just launched the SaferCar app for Android devices that will provide information for car owners and shoppers, including recalls and safety performance. There is already a SaferCar app for iPhone, iPad and iPod Touch users. Other safety notification options from NHTSA include:
- Register Your Cars, Tires and Car Seats: Receive NHTSA email notifications when there is a recall by the federal government. There is no way to locate or notify individual owners of car seats or tires if the product is not registered with the manufacturer or NHTSA.
Check for Open Recalls on Used Cars: Verify with the previous owner or dealer whether a used car has been fixed by using www.safercar.gov, which provides a general search tool to help consumers identify recalls that may affect their vehicle.

Minimum Alcohol Prices Could Help Low-income, High-risk Drinkers
Setting a minimum price for alcohol would have a positive impact on low-income, high-risk drinkers, but little effect on low-income, moderate drinkers, according to a new study in The Lancet. British researchers at the University of Sheffield utilized a computer model to assess the impact of a 73 cents per unit of alcohol minimum on different demographics, finding it would have the greatest positive impact—reducing the amount of alcohol consumption—on the 5 percent of the population defined as high-risk drinkers. "Our study finds no evidence to support the concerns highlighted by government and the alcohol industry that minimum unit pricing would penalize responsible drinkers on low incomes,” said study co-author Petra Meier, director of the Sheffield Alcohol Research Group. “Instead, minimum unit pricing is a policy that is targeted at those who consume large quantities of cheap alcohol. By significantly lowering rates of ill health and premature deaths in this group, it is likely to contribute to the reduction of health inequalities." Read more on alcohol.
Smoking Linked to Most Common Type of Breast Cancer
Adding yet another health risk to the use of tobacco, smoking is linked to an increased risk for the most common type of breast cancer, according to a new study in the journal Cancer. Researchers at the Fred Hutchinson Cancer Research Center in Seattle conducted a population-based study of 778 patients, ages 20-44, with estrogen receptor positive breast cancer (the most common type) and 182 patients with triple-negative breast cancer; there were 938 cancer-free controls. They found that women who were current or recent smokers and had been smoking a pack a day for at least 10 years had a 60 percent increased risk of estrogen receptor positive breast cancer. "The health hazards associated with smoking are numerous and well known. This study adds to our knowledge in suggesting that with respect to breast cancer, smoking may increase the risk of the most common molecular subtype of breast cancer but not influence risk of one of the rarer, more aggressive subtypes," said Christopher Li, MD, PhD.

Low Testosterone Drugs Can Double Heart Attack Risk in Some Men
Ads asking men about their “low T”—or low testosterone levels—have become so common of late that in 2013 sales of the testosterone gel Androgel exceeded those of Viagra. However, a recent study indicates that men under the age of 65 with a history of heart disease see their heart attack risk double shortly after beginning testosterone therapy. The joint study from the UCLA Fielding School of Public Health, the National Institutes of Health and Consolidated Research Inc. appears in the journal PLOS ONE. Researchers decided to perform this larger study after three smaller studies raised concerns about the connection. "We decided to investigate cardiovascular risks of this therapy in a large health care database since these previous studies were modest in size and only focused on men 65 and older," said the study's senior author, Sander Greenland, MD, a professor of epidemiology at the UCLA Fielding School of Public Health and a professor of statistics in the UCLA College of Letters and Science. "Our study allowed us to examine cardiovascular risk in men under the age of 65 and to replicate the findings in men over 65." Read more on heart health.
