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.

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.
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 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.”
- A new infographic from the Measure Up/Pressure Down initiative of the American Medical Group Association provides some key patient information about hypertension, including normal and dangerous ranges of blood pressure—numbers patients should be familiar with.
- A map from the Institute for Health Metrics and Evaluation at the University of Washington shows hypertension levels for 2001 to 2009 by race and gender.
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. The association also previously created another infographic on the FAST warning signs.
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.

“Five years after the Great Recession officially came to an end, the United States has yet to fully recover from the economic devastation sparked by the collapse of an $8 trillion housing bubble and the ensuing turmoil that saw global financial systems teetering on the brink of collapse. But while the economic costs of the downturn have drawn the lion’s share of attention, the damage to our bodies could end up far surpassing the damage to our bank accounts.”
Those are the opening lines of a new special report from the Harvard School of Public Health (HSPH), “Failing Economy, Failing Health: The Great Recession’s Toll on Body and Mind,” detailing how poverty and inequality resulting from the economic maelstrom pulled down so many—and what that will mean for public health in the long term.
“Health is a long-run thing, but the methods we use to analyze current data only estimate short-term effects,” says SV Subramanian, HSPH professor of population health and geography. “It may take awhile for the health impact of the Great Recession to kick in, but once it does, it could be dramatic.”
The data is strong on the links between employment and health—people who are unemployed, underemployed or laid off are less healthy and don’t live as long.
A 2009 study found that in the 12 months after men lost their jobs in mass layoffs, they saw their chances of dying nearly double. While over time the risk lessened it was still significant two decades later. Another study that same year found that losing a job when a business shuts its doors increases the odds of fair or poor health by 54 percent among workers with no preexisting health conditions while also increasing the risk of new health conditions by 83 percent. The stress of the situation, according to the researchers, heightens the odds of stress-related conditions such as stroke, hypertension, heart disease, arthritis, diabetes and psychiatric problems.
Yet another study, this one in 2010, found that about 4 in 10 Americans with heart disease or diabetes and 1 in 5 with cancer said the stress of the Great Recession made it more difficult to manage their illnesses.
What’s more complex is unearthing the pathways behind why this is the case. The HSPH article outlines some of the mechanisms by which unemployment affects health.
Study: Banning Chocolate Milk in Elementary Schools Also Decreases Overall Sales, Increases Waste
Banning chocolate milk in 11 Oregon elementary schools and replacing it with healthier fat-free white milk had the unintended consequence of reducing milk consumption overall, according to a recent study in the journal PLOS One. The study determined that the chocolate milk ban led to a 10 percent overall drop in milk sales; a 29 percent increase in the amount of wasted milk; drops in calcium and protein intake; and a 7 percent decrease in the number of students taking part in the Eugene School District's lunch program. "Given that the role of the federal school meal program is to provide nutritious meals to students who may otherwise have no access to healthy foods, I wouldn't recommend banning flavored milk unless you have a comprehensive plan in place to compensate for the lost nutrients when kids stop drinking milk altogether,” said Nicole Zammit, former assistant director of nutrition services at the Eugene School District in Oregon, in a Cornell University news release. The study was conducted by the Cornell Food and Brand Lab. Read more on nutrition.
CDC: Significant Drops in Five Major Diabetes-related Complications
The last two decades has seen declines in five major diabetes-related complications, according to a new study in the New England Journal of Medicine. Researchers at the U.S. Centers for Disease Control and Prevention (CDC) found declining rates of lower-limb amputation (about 50 percent), end-stage kidney failure (about 30 percent, heart attack (more than 60 percent) , stroke (about 50 percent) and deaths due to high blood sugar (more than 60 percent). “These findings show that we have come a long way in preventing complications and improving quality of life for people with diabetes,” said Edward Gregg, Ph.D., a senior epidemiologist in CDC’s Division of Diabetes Translation and lead author of the study. “While the declines in complications are good news, they are still high and will stay with us unless we can make substantial progress in preventing type 2 diabetes.” A recent study determined that approximately one in 10 U.S. adults have either type 1 or type 2 diabetes.

FDA Sees Rising Number of Cases of Injuries Linked to E-cigarettes
The rising use of e-cigarettes has been accompanied by a rising number of injury complaints linked to e-cigarettes, including burns, nicotine toxicity, respiratory problems and cardiovascular problems, according to new data. From March 2013 to March 2014 there were more than 50 such complaints filed with the U.S. Food and Drug Administration (FDA), roughly the total reported over the previous five years. The findings come as the FDA prepares to regulate e-cigarettes and other "vaping" devices for the first time. Read more on injury prevention.
