Study: Low-income Teens in Better High Schools Engage in Fewer Risky Behaviors
Low-income teenagers attending “high-performing” high schools are less likely than their peers in lower-performing schools to engage in risky behaviors such as carrying a weapon, binge drinking, using drugs other than marijuana and having multiple sex partners, according to a new study in the journal Pediatrics. Researchers analyzed 521 students who were accepted into a high-performing charter school; when compared to 409 students who also applied to top charter schools but were not selected in a random lottery, the kids in the high-performing schools were less likely to engage in at least one of the identified “very risky” behaviors—36 percent, compared to 42 percent. There was no statistical difference for more common risky behaviors, such as lighter drinking and smoking cigarettes. Read more on education.

Too Few People At Risk for Heart Disease are Receiving Recommendations for Aspirin Therapy
Despite the important role it can play in preventing heart disease, only 40 percent of the people who are at high risk of cardiovascular disease reported receiving a doctor’s recommendation for aspirin therapy, according to a new study in the Journal of the American Heart Association. Approximately one-quarter of people at low risk received the recommendation. “Cardiovascular disease is a significant problem in the United States and the appropriate use of prevention strategies is particularly important,” said Arch G. Mainous III, PhD, the study’s lead investigator and chairman of the department of health services research, management and policy at the University of Florida’s College of Public Health and Health Professions, in a release. “Aspirin has been advocated as a prevention strategy but only for certain patients. There are health risks associated with the treatment. It is important that doctors are directing the right patients to get aspirin for cardiovascular disease prevention.” The U.S. Preventive Services Task Force recommends aspirin use to prevent heart attack and stroke in men ages 45-79 and women ages 55-79.

Study: Coping Skills Programs for Mothers of Children With Autism Helps All Involved
Mothers of children with autism who participated in coping skills programs saw reduced stress, illness and psychiatric problems—all of which they are at higher risk for—while also improving their connections with their children, according to a new study in the journal Pediatrics. Such programs also benefit their children, as these risk factors are associated with poorer health outcomes for the children. Researchers entered 243 mothers of children with disabilities (two-thirds of which were autism) into six weeks of either Mindfulness-Based Stress Reduction (mindfulness practice) or Positive Adult Development (positive psychology practice), finding that both reduced stress and other negative impacts.

Child ‘Vehicular Heatstroke’: Good Samaritan Laws and Other Public Health Solutions

file

Earlier this month, following the heatstroke death of a Georgia toddler who was left in a sweltering car for hours, Tennessee became the first state in the nation to pass a law that specifically protects people from liability for forcibly breaking into cars and rescuing kids they think are at risk of heatstroke. The law requires those individuals to call 911 first and follow instructions.

Many states have Good Samaritan laws that may protect people in such instances, but the specifics vary from state to state, according to Cristina M. Meneses, JD, MS, a staff attorney with the Network for Public Health Law’s Eastern Region. A recent Today show poll found that 88 percent of the 44,000 people asked would break into a car to rescue a child they thought was in danger, but specific laws can increase the response—and potentially remove penalties—while raising awareness of the issue. More such laws could soon follow. Janette Fennell, founder and head of KidsAndCars, a nonprofit based in Kansas City, Mo., which advocates for laws that will protect kids from heat in vehicles, said she’s received inquiries from two states about those laws since Tennessee’s law was passed. Another set of laws that KidsAndCars tracks are those that penalize adults for leaving kids in cars. Nineteen states currently have such laws on the books.

“It’s a good deterrent for anyone who might think, ‘Oh, I’ll just leave them in the car for a minute,’” said Fennell, “because it’s often that minute that turns into much longer and results in injury or death.”

According to the National Highway Traffic Safety Administration (NHTSA), more than 40 kids—often under age 2—die each year of “vehicular heatstroke.” Seventeen U.S. kids have died after being left or trapped in car since the beginning of 2014. Fennell and other experts say many people just don’t realize how quickly temperatures can climb in a car, even if the window is cracked open a bit—when outside temperatures are in the low 80's, the temperature inside a vehicle can reach deadly levels in only 10 minutes, even with a window rolled down two inches. Children's bodies, in particular, overheat easily; and infants and children under four years old are at the greatest risk for heat-related illness.

NHTSA research shows that heatstroke deaths and injuries often occur after a child gets into an unlocked vehicle to play without a parent or caregiver's knowledge. Other incidents can occur when a parent or caregiver who is not used to transporting a child as part of their daily routine inadvertently forgets a child sleeping in the back.

Last week, KidsAndCars launched a petition drive to encourage NHTSA to require technology in all cars that would remind a driver that there is a child in the back. There are devices parents can install, but a 2012 study by NHTSA found that none that the agency studied were consistently effective.

“You get a warning if you don't buckle your seatbelt, leave a car door open, your gas is low or you leave your headlights on,” said Fennell. “If a child is left behind then you absolutely need a warning.”

Guidelines from NHTSA and other safety experts aimed at never leaving a child unattended in a car include:

  • Make a habit of looking in the vehicle—front and back—before locking the door and walking away
  • Ask childcare providers to call if a child doesn't show up for care as expected
  • Put items in the back seat you’ll have to retrieve such as a purse or briefcase, or put a stuffed animal in sight of the driver to indicate there’s a child in the car.

Strokes Fall Among Older Americans
Fewer older Americans are having strokes and those who do have a lower risk of dying from them, according to researchers at the Johns Hopkins Bloomberg School of Public Health. The study, published in JAMA, followed close to 15,000 stroke-free patients ages 45 to 64, beginning in the 1980s and ending in 2011. It found a 24 percent overall decline in first-time strokes in each of the last two decades and a 20 percent overall drop per decade in deaths after stroke. However, the decline was found mainly in people over age 65, with little progress in reducing the risk of strokes among younger people. The researchers say the decrease in stroke incidence and mortality is partly due to more successful control of risk factors such as blood pressure, smoking cessation and use of statin medications for controlling cholesterol, but that more efforts are needed to reduce strokes in younger people, including reducing obesity and diabetes and increasing physical activity.

Study: Insufficient Sleep Can Harm Memory
Lack of sleep, currently considered a public health epidemic in the United States, can also lead to errors in memory, according to a new study in Psychological Science. The study found that participants who didn’t get a full night’s sleep were more likely to make mistakes on the details of a simulated burglary they were shown in a series of images. “We found memory distortion is greater after sleep deprivation,” said Kimberly Fenn, an associate professor of psychology at Michigan State University and a co-investigator of the study. “And people are getting less sleep each night than they ever have.” The U.S. Centers for Disease Control and Prevention has linked the insufficient sleep epidemic to car crashes, industrial disasters and chronic diseases such as hypertension and diabetes.

New EPA Graphic Will Give Consumers More Information on Insect Repellent Products

file

The U.S. Environmental Protection Agency (EPA) has recently released a new graphic design available for use by insect repellent makers to more easily show how long the product is effective. “We are working to create a system that does for bug repellents what SPF labeling did for sunscreens,” said Jim Jones, Assistant Administrator of the Office of Chemical Safety and Pollution Prevention. “By providing vital information to consumers, this new graphic will help parents, hikers and the general public better protect themselves and their families from serious health threats caused by mosquitoes and ticks.” The release of the graphic design was accompanied by a joint statement from the EPA and the U.S. Centers for Disease Control and Prevention (CDC) urging the public to use insect repellents and take other precautions to avoid biting insects that carry serious diseases, including Lyme and West Nile virus. Incidence of insect-borne diseases is on the rise, according to the CDC. In order to place the new graphic on their labels, manufacturers must submit a label amendment, including test results on effectiveness. The public could see the graphic on repellent products early next year. Read more on infectious disease.

CDC: 60 Percent of Diners Will Use Menu Calorie Counts When Available
Approximately 6 in 10 U.S. adults will choose their restaurant meals in part because of menu label information when it’s available, according to the U.S. Centers for Disease Control and Prevention’s (CDC) latest Morbidity and Mortality Report. Researchers analyzed the self-reported usage of 118,013 adults in 17 states in 2012 to determine that about 57 percent will look to the provided calorie information. New York had the highest rate, with 61.3 percent, while Montana had the lowest, at 48.7 percent. Federal law requires calorie information be provided by any restaurant with 20 or more locations; while the regulations are not yet final, many establishments already voluntarily provide menu labeling, according to the CDC.

Depression, Stress, Hostility Tied to Higher Stroke Risk
Depression, stress and hostility may be linked to a higher risk for stroke, according to a new study in the journal Stroke. Using information provided by approximately 7,000 adults who did not have heart disease or a history of stroke at the beginning of the study, researchers followed up nearly nine years later and determined that depression was associated with an 86 percent increased chance of a stroke or a transient ischemic attack, stress was associated with a 59 percent increase and hostility doubled the risk. “[C]hronic stress and negative emotions are important psychological factors that affect one's health, and findings from this study link these factors to brain health in particular," said the study's lead author, Susan Everson-Rose, an associate professor of medicine at the University of Minnesota, according to HealthDay. "Patients and their health care providers should be aware that experiences of chronic stress and negative emotional states can increase risk for stroke.” Read more on heart health.

Washington State Sees Most Measles Cases Since 1996
A slight decline in Washington State’s mumps and rubella vaccination rate has coincided with the state’s highest number of measles case in 18 years, according to officials. Washington has reported 27 cases so far this year and is currently in the midst of its third outbreak. While homegrown measles was declared officially eliminated from the United States in 2000, infections from people who have travelled overseas remain a threat. There were 554 total cases of measles and 17 outbreaks reported in the United States between Jan. 1 and July 3 of this year. Read more on infectious diseases.

AHA to Fund Research Network for the Prevention of Heart Disease, Stroke
With a $15 million grant from the American Heart Association (AHA), four major medical institutions are coming together to form a research network with the goal of preventing heart disease and stroke. The Strategically Focused Prevention Research Network Centers will include investigators at Northwestern University in Chicago, Vanderbilt University in Nashville, the Icahn School of Medicine at Mount Sinai in New York City and the University of Texas-Southwestern Medical Center in Dallas. “Heart attack and stroke can strike suddenly, and frequently without warning. The best way to reduce premature mortality from cardiovascular diseases and stroke is to prevent the development of the risk factors that lead to these conditions,” said AHA President Elliott Antman, MD, professor of medicine at Harvard Medical School and a senior physician in the cardiovascular division of the Brigham and Women’s Hospital in Boston, in a release. “Scientists working in these research centers are helping to discover the mechanisms that will allow all Americans to live healthier lives, helping lead us to a culture of health.” Read more on heart health.

Study: One-Third of U.S. Total Knee Replacements ‘Inappropriate’
Approximately one-third of all total knee replacements in the United States are unnecessary and “inappropriate” under a patient classification system used in Spain, according to a new study in the journal Arthritis & Rheumatology. Researchers said the findings demonstrate a need for the United States to develop similar patient selection criteria so as to limit the unneeded surgeries. There are more than 600,000 total U.S. knee replacements annually—meaning that approximately 200,000 are unnecessary, according to the study—and from 1991 to 2010 the number of Medicare-covered replacements climbed by approximately 162 percent annually.

Kids’ ADHD Medications Not Linked to Increase Risk of Substance Abuse
While children with attention-deficit/hyperactivity disorder (ADHD) are twice as likely to abuse drugs, the medications prescribed to treat ADHD do not play a role in the increased risk, according to a new study in the journal Pediatrics. In fact, researchers determined that the combination of behavioral techniques and ADHD medications actually lowers the risk of substance abuse. "Obviously, the medications that are used to treat ADHD have the potential for abuse, but the vast majority of children with ADHD do not develop a substance abuse problem," said Michael Duchowny, MD, a pediatric neurologist at Miami Children's Hospital. "More research has to be done to find out why some children are more susceptible than others." Common ADHD medications include amphetamines such as Adderall or Dexedrine, and methylphenidates such as Concerta, Metadate CD or Ritalin. Read more on substance abuse.

New NIH Pain Research Database Could Be a Key Tool in the Fight Against Prescription Drug Abuse

A new database on pain research established by the National Institutes of Health (NIH) and several other federal agencies might help practitioners choose more effective and safer options for their patients dealing with pain. It could also potentially reduce reliance on opioid drugs, which often turns patients into addicts and creates an easy source of the drugs for potential abusers.

The database, launched last week, is called the Interagency Pain Research Portfolio (IPRP) and offers information on federal pain research projects. According to the NIH, pain is a symptom of many disorders and can be a disease itself; the economic cost of pain is estimated to be hundreds of billions of dollars annually in lost wages and productivity.

“This database [allows] the public and the research community...to learn more about the breadth and details of pain research supported across the federal government. They can search for individual research projects or sets of projects grouped by themes uniquely relevant to pain,” said Linda Porter, PhD, Policy Advisor for Pain at the National Institute of Neurological Disorders and Stroke (NINDS), part of the NIH.

Both in public speeches and private briefings with reporters, U.S. Centers for Disease Control and Prevention Director Tom Frieden, MD, MPH, has called on physicians to find alternatives to narcotics for pain patients when medically advisable, such as guided imagery and other forms of relaxation. He’s also called for starting with less potent medications than narcotics, in order to reduce the chance of addiction and to introduce far fewer amounts of prescription drugs into the community where they are often taken from medicine cabinets by people—especially young adults—for whom they’re not prescribed. According to the Substance Abuse and Mental Health Administration, approximately 22 million people nationwide have taken narcotic pain relievers for non-medical reasons.

U.S. Food and Drug Administration head Margaret Hamburg, MD, also spoke on the subject during a town hall meeting last week on prescription drug abuse, hosted by the Johns Hopkins School of Public Health and the Clinton Foundation. Hamburg said that “we need to recognize that opiates are... probably most often not the treatment strategy of first choice...but it may be the option a provider knows best. We need to actively engage with the scientific research community and industry to try to develop new non-opiate, non-addictive pain strategies...”

Hypertension ‘Kills More People Around the World than Anything Else’

“Hypertension affects nearly one in three adults and kills more people around the world than anything else. It is both too common and too often poorly controlled.”

So said Tom Frieden, MD, MPH, director of the U.S. Centers for Disease Control and Prevention (CDC), during a panel discussion at the annual meeting of the American Society of Hypertension (ASH) this past weekend. The panel was convened by ASH, the American Heart Association and the CDC to launch a project supporting improved control of hypertension worldwide. According to the panel an estimated 970 million people have hypertension worldwide, and the disease is responsible for more than nine million deaths, as hypertension can lead to heart disease and stroke.

Data from the groups finds that rates of hypertension have increased in both developed and developing nations, due in part to an aging population and lifestyles that include high salt diets and low physical activity.

For the developing world, the CDC; the Pan American Health Organization; and other regional and global stakeholders are identifying both cost effective medicines and inexpensive delivery strategies for the drugs to help patients afford and receive them.

In the United States, the Affordable Care Act is expected to increase the number of people on hypertension medications, but despite the availability of coverage for hypertension diagnosis and treatment there remains concern over disparities. A study of more than 16,000 members of the Hispanic community published in the American Journal of Hypertension earlier this year found that while the prevalence of hypertension among Hispanics is nearly equal to that of non-Hispanic whites, diagnosis of the disease is much lower, as is general awareness of its symptoms and treatment options.

"Given the relative ease of identifying hypertension and the availability of low-cost medications, enabling better access to diagnostic and treatment services should be prioritized to reduce the burden of cardiovascular disease on Hispanic populations,” said Paul Sorlie, MD, the lead author of the study and an epidemiologist with the National Heart, Lung and Blood Institute. “This study gives us the information needed to support the development of policies that can improve this access and, subsequently, the overall health of countless US citizens.”

Public Health Campaign of the Month: ‘Save a Minute’ Stroke PSA

May is stroke awareness month and a new infographic from the American Stroke Association wants everyone to know minutes count when a stroke hits. The campaign uses research published by the Association this year in the campaign infographic to let people know that for each minute shaved off stroke response in a hospital, patients get back days of healthy living.

The infographic includes the  FAST warning signs and symptoms for stroke:

  • Face drooping
  • Arm weakness
  • Speech difficulty
  • Time to call 911

>>Bonus Content: The American Stroke Association has a site full of patient education resources on stroke awareness and prevention, including a very effective PSA on body language to help teach the FAST warning signs of stroke.

Too Few Disabled Adults Participate in Physical Activities
Working-age adults with disabilities who get no aerobic physical activity are 50 percent more likely to have a chronic disease such as cancer, diabetes, stroke or heart disease than are their active peers, according to a Vital Signs report released today by the U.S. Centers for Disease Control and Prevention (CDC). Most adults with disabilities are able to participate in physical activity, yet nearly half (47 percent) of them get no aerobic physical activity. An additional 22 percent aren’t active enough. However, only about 44 percent of adults with disabilities who saw a doctor in the past year got a recommendation for physical activity.

The key findings of the report include:

  • Working-age adults with disabilities are three times more likely to have heart disease, stroke, diabetes or cancer than are adults without disabilities.
  • Nearly half of adults with disabilities get no aerobic physical activity, an important protective health behavior to help avoid these chronic diseases.
  • Inactive adults with disabilities were 50 percent more likely to report at least one chronic disease than were active adults with disabilities.
  • Adults with disabilities were 82 percent more likely to be physically active if their doctor recommended it.
  • The CDC recommends that adults with disabilities talk to their doctor about how much and what kind of physical activity is right for them, and that doctors and other health professionals recommend options that fit each disabled patients. The agency has created a resource page to help health professionals direct disabled patients to fitness options.

HHS: Quality Improvement Efforts Saved 15,000 Lives, $4B in Health Spending
New data from the U.S. Department of Health and Human Services (HHS) indicates that quality improvements to the country’s health care system helped prevent nearly 15,000 deaths in hospitals, avoid 560,000 patient injuries and saved approximately $4 billion in health spending from 2011 to 2012. The preliminary data also indicates an overall nine percent decrease in hospital-acquired infections over that period. “We applaud the nationwide network of hospital systems and providers that are working together to save lives and reduce costs,” said HHS Secretary Kathleen Sebelius.  “We are seeing a simultaneous reduction in hospital readmissions and injuries, giving patients confidence that they are receiving the best possible care and lowering their risk of having to be readmitted to the hospital after they get the care they need.” Read more on HHS.

AAP: Drunk Driving Remains a Significant Safety Threat for U.S. Children
Despite improvements in safety efforts and the data, motor vehicle crashes remain a leading cause of death for U.S. children and in approximately 20 percent of the deaths at least one of the drivers is legally drunk, according to a new study in the journal Pediatrics. Researchers examined National Highway Traffic Safety Administration data of children under age 15 who were killed in a traffic crash between 2001 and 2010. The study determined that child deaths with an alcohol-impaired driver decreased by 41 percent over that period, with a total of 2,344 victims. Researchers also determined that 61 percent of impaired drivers were unrestrained at the time of the crash and one-third did not have a valid driver’s license. The researchers said that communities need to “urge states and communities to target efforts at protecting children from impaired drivers and increasing use of age- and size-appropriate restraints for child passengers,” according to a release from the American Academy of Pediatricians.

CDC: Many Annual Deaths Are Preventable
Each year, nearly 900,000 Americans die prematurely from the five leading causes of death—yet 20 to 40 percent of the deaths from each cause could be prevented, according to a new study from the U.S. Centers for Disease Control and Prevention (CDC). The five leading causes of death in the United States are heart disease, cancer, chronic lower respiratory diseases, stroke and unintentional injuries. Together they accounted for 63 percent of all U.S. deaths in 2010, with rates for each varying greatly from state to state. The study suggests that if all states had the lowest death rate observed for each cause, it would be possible to prevent:

  • 34 percent of premature deaths from heart diseases, prolonging about 92,000 lives
  • 21 percent of premature cancer deaths, prolonging about 84,500 lives
  • 39 percent of premature deaths from chronic lower respiratory diseases, prolonging about 29,000 lives
  • 33 percent of premature stroke deaths, prolonging about 17,000 lives
  • 39 percent of premature deaths from unintentional injuries, prolonging about 37,000 lives

Modifiable risk factors such smoking and obesity are largely responsible for each of the leading causes of death, according to the CDC. Many of these risks are avoidable by making changes in personal behaviors, while others are due to social, demographic, environmental, economic and geographic disparities in the neighborhoods in which people live and work. Southeastern states had the highest number of preventable deaths for each of the five causes. The study authors suggest that states with higher rates can look to states with similar populations, but better outcomes, to see what they are doing differently to address leading causes of death.

Cost of Fighting Wildfires Projected to Skyrocket this Year
The U.S. Department of the Interior (DOI) is projecting that fighting wildfires in 2014 will cost $470 more than is currently available."With climate change contributing to longer and more intense wildfire seasons, the dangers and costs of fighting those fires increase substantially," said DOI Assistant Secretary of Policy, Management and Budget Rhea Suh. Drought conditions in the West, especially in California, combine with other factors to predict a dangerous fire season. Last year, 34 wildfire firefighters died and wildfires burned 4.1 million acres and 1,000 homes. The department would have to divert funds from other programs, which it has previously done. Department officials say climate change is a factor in the increase in wildfires. Read more on the environment.

Starting Antidepressant Treatment at Highest Doses Increases Suicide Risks for Kids and Teens
Children and young adults who start antidepressant therapy at high doses, rather than at the typically prescribed doses, appear to be at greater risk for suicidal behavior during the first 90 days of treatment, according to a study in JAMA Internal Medicine. The rate of suicidal behavior among children and young adults who started antidepressant therapy at high doses was about twice as high compared with a control group of patients who received a typically prescribed dose.
