NHTSA: Motorcoaches, Large Buses to Require Seatbelts for All Passengers and Driver
New motorcoaches and large buses will be required to provide lap and shoulder seatbelts for all passengers and driver, under a new rule issued by the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA). While the buses are an overall safe way to travel, the large numbers of people they carry and the high speeds at which they travel mean a single collision can lead to a significant number of injuries, according to NHTSA. An average of 7,934 riders are injured each year in motorcoaches, and an average of 21 passengers are killed. "Buckling up is the most effective way to prevent deaths and injuries in all vehicular crashes, including motorcoaches," said Federal Motor Carrier Safety Administrator Anne S. Ferro, in a release. "Requiring seat belts in new models is another strong step we are taking to reach an even higher level of safety for bus passengers." The rule will apply to buses with a gross vehicle weight rating (GVWR) greater than 26,000 pounds,) excluding transit buses and school buses. Read more on transportation.

Study: Women With Breast Cancer Should Get Mammograms Every 12 to 18 Months
Breast cancer patients should undergo mammograms every 12 to 18 months to determine whether their cancer has spread to the lymph nodes, according to a new study to be presented today at the annual meeting of the Radiological Society of North America. Study researcher Lilian Wang, MD, evaluated more than 300 women who were diagnosed with breast cancer because of a routine mammogram, dividing them into three groups based on their treatment history. She found that only 9 percent of the women who had 12- to 18-month intervals between mammograms saw their cancer spread to their lymph nodes; the rates were 21 percent for those who waited one-and-a-half to three years and 15 percent for those who waited three or more years. "If you catch someone with early stage cancer, they are going to need less extensive surgery, and maybe no chemo," said Laura Kruper, MD, director of the Cooper-Finkel Women's Health Center at the City of Hope Cancer Center, in Duarte, Calif., who was not a part of the study. "[The new study] adds more power behind the fact that we do need screening mammograms starting at age 40 and every year.” Read more on cancer.

FDA: Certain HeartStart AEDs May Not Work During Cardiac Emergencies
The U.S. Food and Drug Administration (FDA) announced yesterday that certain automated external defibrillator (AED) devices made by Philips Medical Systems may not function properly when needed. In a new safety communication, FDA revealed that the devices may not deliver the needed shock to restore normal heart rhythm during a cardiac emergency. “The FDA advises keeping all recalled HeartStart AEDs in service until you obtain a replacement from Philips Healthcare or another AED manufacturer, even if the device indicates it has detected an error during a self-test,” said Steve Silverman, director of the Office of Compliance in the FDA’s Center for Devices and Radiological Health. “Despite current manufacturing and performance problems, the FDA considers the benefits of attempting to use an AED in a cardiac arrest emergency greater than the risk of not attempting to use the defibrillator.” Read more on heart health.

Study: Gay, Bisexual Men Who Know Their HIV Status Less Likely to Engage in Risky Sex
Gay and bisexual men who know their HIV status are far less likely to engage in unprotected sex, which in lessens the sexual risk both for them and for their partner, according to the U.S. Centers for Disease Control and Prevention's (CDC) latest Morbidity and Mortality Weekly Report. An analysis of HIV-positive men who have sex with men (MSM) in 20 U.S. cities found that about 33 percent of those who did not know their status engaged in unprotected sex with a partner, and also did not know the status of the partner; men who knew their status were 60 percent less likely to do so, for an overall rate of 13 percent. MSM account for about two-thirds of new HIV infections and about half of the 1.1 million people in the United States with HIV. "While we remain concerned about potentially increasing levels of sexual risk, it is encouraging to see that risk is substantially lower in those who know they have HIV," said CDC Director Tom Frieden, MD, MPH. "HIV testing remains one of our most powerful tools to reverse the epidemic. Everyone should know their HIV status." Read more on HIV/AIDS.

Improved HealthCare.gov Faces Next Challenges
HealthCare.gov, the online portal for the Affordable Care Act, faces another test starting today as the Obama administration announced it met a weekend deadline to make the site easier to use and more accessible for most users. The original launch of the site was met with must frustration across the county as many people were unable to navigate the site properly or even to log in. The administration now expects a rush of people--both a backlog and people who have yet to try the site--to enroll by the December 23 deadline for coverage that would begin January 1. Multiple organizations, including Enroll America and AIDS Alabama, have announced plans to help people enroll. Jeffrey Zients, an administration advisor, warned that the post-Thanksgiving wave of enrollment could still overwhelm the servers at times. Read more on the Affordable Care Act.

Study: Energy Drinks Can Increase Strain on Heart
People who consume energy drinks can experience rapid heart contractions and increased strain on the heart up to an hour later, according to new research to be presented today at the annual meeting of the Radiological Society of North America, in Chicago. The findings raise concerns over the effects of caffeine and taurine on heart health, especially for people who already suffer from heart disease. Researchers used magnetic resonance imaging to measure the heart function of 18 health people both before and after they consumed an energy drink, finding an average 6 percent increase in the heart contraction rate afterward. "We know there are drugs that can improve the function of the heart, but in the long term they have a detrimental effect on the heart," said Williams, a cardiology professor at Wayne State University School of Medicine, in Detroit. Researchers noted that further study is needed to determine the reason for the apparent link. Read more on heart health.

Kids Today Slower, Less Fit than Their Parents as Kids
An average child in 1975 in a one-mile race with an average child today would win by an average of a minute and a half, according to new research. Kids today are also about 15 percent less aerobically fit, with heart endurance falling an average of 6 percent per decade from 1970 to 2000. That means today’s kids are more likely to be unhealthy in adulthood, with weaker hearts, thinner bones and overall lower quality of life. Grant Tomkinson, a senior lecturer in the University of South Australia's School of Health Sciences, pointed to a number of factors, including communities designed to discourage walking, bicycling and backyard play; reduced or even completely absent physical education in schools; and the prevalence of television, computer, tablet and smartphone screens that keep kids indoors. "We all live in an environment that's toxic for exercise, and our children are paying the price," Tomkinson said. Tomkinson said in order to reverse this trend, kids need at least 60 minutes of serious physical exercise a day, such as running, swimming or cycling. "You want exercise to be fun, but there needs to be some huff and puff there as well," he said. "It needs to make them somewhat tired." Read more on physical activity.

Study: Symptoms of ‘Sudden’ Cardiac Arrest Can Be Seen Up to a Month Earlier
Symptoms of “sudden” cardiac arrest can be seen up to a month beforehand in middle-age men, according to new findings presented this week at the annual scientific sessions of the American Heart Association, held this year in Dallas. Researchers looked at the medical records of 567 men, ages 35-65, who had out-of-hospital heart attacks, finding that approximately 53 percent showed symptoms beforehand. They included chest pain (56 percent); shortness of breath (13 percent); and dizziness, fainting or palpitations (4 percent). Sumeet Chugh, senior author of the study and associate director for genomic cardiology at the Cedars-Sinai Heart Institute in Los Angeles, said the “entirely unexpected” findings show that people may be able to prevent heart attacks if they seek treatment earlier for these symptoms. "The findings were entirely unexpected," said "We never thought more than half of these middle-aged men would have had warning signs so long before their cardiac arrests,” Chugh said. “Previously we thought most people don't have symptoms so we can't do anything about it."

ACS Tips on Quitting Tobacco for Tomorrow’s ‘Great American Smokeout’
Tomorrow is the American Cancer Society (ACS) Great American Smokeout, held every year on the third Thursday of November. The annual event was founded to encourage people to quit using tobacco—perhaps to stop smoking on that day, or to make a plan on how to quit at a later date—and to provide the tools and resources that can help the decision stick. According to ACS, research shows that people are most successful at quitting tobacco when they have support, and recommends combing two or more of the following tactics to improve the odds:

  • Telephone smoking-cessation hotlines
  • Stop-smoking groups
  • Online quit groups
  • Counseling
  • Nicotine replacement products
  • Prescription medicine to lessen cravings
  • Guide books
  • Encouragement and support from friends and family members

People can call 1-800-227-2345 for more information or go to "Stay Away from Tobacco" at Cancer.org. Read more on tobacco.

Six Killed, Dozens Injured as Tornados Sweep Across the U.S. Midwest
At least six people were killed and dozens left injured after a flurry of tornados swept through the American Midwest yesterday. Tornado watches were announced for Illinois, Indiana, Iowa, Michigan, Missouri, Ohio and Wisconsin; by the end of the day, an estimated 77 had touched down, mostly in Illinois, according to the National Weather Service. The severe weather left thousands without power (approximately 89,000 in Northern Illinois alone) and leveled entire neighborhoods. “I went over there immediately after the tornado, walking through the neighborhoods, and I couldn’t even tell what street I was on,” said Tyler Gee, an alderman on the Chicago City Council, to radio station WBBM in Chicago. “It just completely flattened some of the neighborhoods here in town, hundreds of homes.” Read more on disasters.

NHTSA: 2012 Highway Fatalities Up for the First Time Since 2005
While highway traffic fatalities continue to hover around historic lows, the total number of deaths increased by 1,082 from 2011 to 2012, to a total of 33,561, the first increase since 2005. The findings are part of the U.S. Department of Transportation's National Highway Traffic Safety Administration’s (NHTSA) 2012 Fatality Analysis Reporting System (FARS) data. "Highway deaths claim more than 30,000 lives each year and while we've made substantial progress over the past 50 years, it's clear that we have much more work to do," said U.S. Transportation Secretary Anthony Foxx. "As we look to the future, we must focus our efforts to tackle persistent and emerging issues that threaten the safety of motorists, cyclists and pedestrians across the nation." Read more on safety.

Heart Groups’ New Risk Guidelines, Calculator Apparently Flawed
The risk guidelines and calculator released last week by the American Heart Association and the American College of Cardiology, meant to improve the assessment of potential cardiovascular disease, could possibly instead greatly overestimate the risk and as built could lead to millions of unnecessary statin prescriptions. The potential problems, first identified by two Harvard Medical School professors, will be published today in The Lancet. One possible explanation for the problem is that the system relies on old data, while populations and their behaviors have changed. Steven Nissen, MD, chief of cardiovascular medicine at the Cleveland Clinic and a past president of the American College of Cardiology, called the findings “stunning,” adding “We need a pause to further evaluate this approach before it is implemented on a widespread basis.” However, after emergency meetings at the American Heart Association’s annual meeting this weekend in Dallas, both organizations said despite the apparent flaws the guidelines are still a major step forward, noting that patients are also advised to speak with their doctors, and not simply follow the results of the calculator.

CDC: Emerging Tobacco Products Gaining Popularity among Middle and High School Students
A new report from the U.S. Centers for Disease Control and Prevention (CDC) finds that emerging tobacco products such as e-cigarettes and hookahs are quickly gaining popularity among middle- and high-school students, but with no significant decline in students’ cigarette smoking or overall tobacco use. The new report was culled from data in the 2012 National Youth Tobacco Survey, which shows that electronic cigarette use rose among middle school students from 0.6 percent in 2011 to 1.1 percent in 2012 and among high school students from 1.5 percent to 2.8 percent. Hookah use among high school students rose from 4.1 percent to 5.4 percent from 2011 to 2012. 

The study authors say the increase in the use of electronic cigarettes and hookahs could be due to an increase in marketing, availability and visibility of the products, as well as the perception that they may be safer alternatives to cigarettes. While electronic cigarettes, hookahs, cigars and certain other new types of tobacco products are not currently subject to regulation by the U.S. Food and Drug Administration, the agency has said recently that it plans to issue a proposed rule that would deem products meeting the statutory definition of a "tobacco product" to be subject to the Federal Food, Drug, and Cosmetic Act—as cigarettes are.

The researchers say cigar use in young adults is of particular concern. During 2011-2012, cigar use increased dramatically among non-Hispanic black high school students from 11.7 percent to 16.7 percent, and has more than doubled since 2009, and similar to the rate of cigarette use among high school males (16.3 percent).

Workplace Injuries Cost U.S. Healthcare System $13.1B in 2011
With nearly the highest injury rate of all U.S. industries, workplace injuries cost the U.S. healthcare system approximately $13.1 billion and more than 2 million lost workdays in 2011, according to a new study in the journal Professional Safety. “Healthcare worker injury rates are only less than outdoor wilderness professions, such as commercial loggers and fishermen. The injury rates are sky high," said report author Scott Harris, PhD, MSPH, the director of EHS advisory services for UL Workplace Health and Safety. The study found that 15.2 million employees were injured that year alone, with the most common injuries coming from slips, trips, falls, violence and chemical exposure; nurses experienced the highest rates. The report concluded that hospitals “would benefit from more rigorous and frequent inspections from the Occupational Safety and Health Administration.” Read more on injury prevention.

Even Healthy Overweight People at Increased Risk for Heart Disease
Even overweight people who are otherwise healthy are at increased risk for heart disease, according to a new study in JAMA Internal Medicine. Previous research indicated that higher-than-normal risk was linked to a collection of risk factors known as “metabolic syndrome,” including large waist circumference, high blood pressure, high triglycerides, low "good" cholesterol and diabetes. People have metabolic syndrome if they have at least three of the risk factors. However, in a study of 71,527 adults without heart problems, researchers determined that risk went up as weight went up, even if metabolic syndrome factors were absent. "Whether you call someone as having or not having metabolic syndrome as kind of a yes/no variable, is not helpful clinically and it doesn't make sense biologically," said Meir J. Stampfer, from the Harvard School of Public Health, according to Reuters. "It's basically just that the metabolic syndrome is waiting to happen to those people." Read more on obesity.

New Statin Guidelines Call For Greater Use
New guidelines from the American Heart Association and American College of Cardiology could dramatically increase the number of people taking cholesterol-lowering statins. The guidelines call for people to take statins if they already have heart disease, if their bad (LDL) cholesterol is extremely high (190 milligrams per deciliter of blood or more) or if they're middle-aged with type 2 diabetes. They also advise statins for people who are 40-75 years old with an estimated 10-year risk of heart disease of 7.5 percent or more. Previous guidelines had advised doctors to follow rigid clinical guidelines that trigger statin use when cholesterol levels reach a certain threshold. The new policy "suggests treatment should be individualized and that, depending on your risk, you may need a higher dose of a more potent statin than if your risk is lower," said Hector Medina, MD, a cardiologist at Scott & White Healthcare in Round Rock, Texas, according to HealthDay.

Airport Noise May Increase Heart Disease and Stroke Risk
People who live near busy international airports may be at increased risk of heart disease and stroke due to the high levels of noise, according to two new studies in the British Medical Journal. One study looked at hospital admissions around London Heathrow airport, finding the risks were 10 to 20 percent higher when compared to areas with the least noise. The other study, by researchers at the Harvard School of Public Health and Boston University School of Public Health, analyzed data on more than 60 million Americans ages 65 and older living near 89 airports, finding that areas with 10 decibel higher aircraft noise also saw a 3.5 percent increase in the hospital admission rate. Researchers say the link needs further study to show causation. "The exact role that noise exposure may play in ill health is not well established," said Anna Hansell of Imperial College London, who led the British study. "However, it is plausible that it might be contributing, for example by raising blood pressure or by disturbing people's sleep." The findings indicate that populated areas must be looked at closely when communities consider expanding large airports. Read more on heart health.

Private Talk Sessions with NICU Nurses Ease Anxiety in Mothers of Premature Babies
“Listening matters” when it comes to easing the worries of the mothers of premature infants. One-on-one talks sessions between NICU nurses and the mothers can help reduce feelings of anxiety, confusion and doubt, according to a new study in the Journal of Perinatology. "Having a prematurely born baby is like a nightmare for the mother," said Lisa Segre, an assistant professor in the University of Iowa College of Nursing. "You're expecting to have a healthy baby, and suddenly you're left wondering whether he or she is going to live." The study looked at 23 mothers who when through an average of five 45-minute sessions, find they gave mothers a chance to really talk about their worries and were effective at easing concerns across the board. "Listening is what nurses have done their whole career," said NICU nurse and study co-author Rebecca Siewert. "We've always been the ones to listen and try to problem solve. So, I just think it was a wonderful offshoot of what nursing can do. We just need the time to do it." Read more on maternal and infant health.

Early Puberty Tied to Great Risk of Experimentation with Cigarettes, Alcohol and Marijuana
Early puberty is linked to increased risk of experimentation with cigarettes, alcohol and marijuana, according to a new study in the journal Addiction. Puberty typically begins between the ages of 9 and 10, will girls on average beginning it earlier than boys. "While puberty is often thought of as a solely biological process, our research has shown that pubertal development is a combination of biological, psychological and social processes that all likely interact to influence risk-taking behavior like substance use," said study author Jessica Duncan Cance, a public health researcher at the University of Texas at Austin. "Our study suggests that being the first girl in the class to need a bra, for example, prompts or exacerbates existing psychological and social aspects that can, in turn, lead to substance use and other risky behaviors early in life.” Read more on pediatrics.

AHA: Health Care Providers Should Emphasize Healthy Behaviors in Cardio Care
When it comes to treating cardiovascular health, health care providers should place just as much emphasis on correcting healthy behaviors as they do addressing the physical indicators of the risk for heart disease, according to a new statement from the American Heart Association (AHA). “We’re talking about a paradigm shift from only treating biomarkers — physical indicators of a person’s risk for heart disease — to helping people change unhealthy behaviors, such as smoking, unhealthy body weight, poor diet quality and lack of physical activity,” said lead author Bonnie Spring, PhD, a professor of preventive medicine and psychiatry and behavioral sciences at Northwestern University in Chicago. “We already treat physical risk factors that can be measured through a blood sample or a blood pressure reading in a doctor’s office, yet people put their health at risk through their behaviors. We can’t measure the results of these behaviors in their bodies yet.”

The AHA’s recommended “five A’s” to patient treatment:

  • Assess a patient’s risk behaviors for heart disease.
  • Advise change, such as weight loss or exercise.
  • Agree on an action plan.
  • Assist with treatment.
  • Arrange for follow-up care.

AHA’s goals for 2020 include improving the cardiovascular health of all Americans by 20 percent, while also reducing deaths from cardiovascular diseases and stroke by 20 percent. Read more on heart health.

Study: 1 in 10 Youth Admit to Sexual Violence
Approximately one in 10 teenagers and young adults admit to sexual violence, according to a new study in the journal JAMA Pediatrics. Researchers said violent pornography may be partially to blame for the acts, which included coercive sex, sexual assault and rape, and most often with a romantic partner. What’s more, about two in three said the act was never discovered, so there was never a punishment. "We know a bit about youth who are victims of sexual violence, but we don't know much at all about youth as perpetrators," said study co-author Michele Ybarra, president and research director of the Center for Innovative Public Health Research in San Clemente, Calif. "It's important we know more if we're going to reduce the sexual-violence rate." Ybarra said sexual-violence-prevention programs should emphasize the understanding of explicit consent and the tactics of coercive sex. "They may say, 'Unless you have sex with me, I'm going to go have sex with someone else,’” said Angela Diaz, MD, MPH, director of Mount Sinai Hospital's Adolescent Health Center. "Young people have to learn that if their partner says that, maybe they're better off if they do go somewhere else." Programs should also focus on the role of the bystander and the importance of reporting incidents. Read more on violence.

Salmonella Outbreak Sickens 278 People in 18 States
Approximately 278 people in 18 states have become sick from a salmonella outbreak linked to raw chicken products, according to the U.S. Department of Agriculture. The products were produced at three California plants owned by Foster Farms and distributed mostly to retailers in California, Oregon and Washington state. Local, state and federal health officials made the connection. While the outbreak is “ongoing,” there is currently no recall as the U.S. Centers for Disease Control and Prevention is working with state health departments to monitor the matter while the Food Safety and Inspection Service investigated the outbreak.

Study: Top Athletes Endorse Junk Food More Often Than Healthy Food
A new study of professional athletes’ food and beverage endorsements found that more often than not their paid support is given to products that are energy-dense and nutrient-poor, according to a new study in the journal Pediatrics. The study looked at 512 brands endorsed by 100 different athletes, finding that “Seventy-nine percent of the 62 food products in athlete-endorsed advertisements were energy-dense” and “93.4% of the 46 advertised beverages had 100% of calories from added sugar.” Denver Broncos player Peyton Manning and Miami Heat player LeBron James had the most endorsements for the energy-dense, nutrient-poor food and beverages. "I hope this paper inspires some reflection on the part of America's athletes and professional sports leagues, as well as all other celebrities for that matter,” said Center for Science in the Public Interest Executive Director Michael F. Jacobson, in a statement. Read more on nutrition.

U.S. Task Force Recommends Against Blood Pressure Screening for Kids, Teens
Despite recommendations from several expert groups, the U.S. Preventive Services Task Force is not recommending that health care professionals respond to the growing obesity crisis by screening children and teens for high blood pressure. The panel concluded that more study into the issue is needed, and that in the mean time there are other, known avenues toward lowering youth obesity and improving cardiovascular health. "We don't know if lowering blood pressure in youth leads to improved cardiovascular health in adulthood,” said panel member Kirsten Bibbins-Domingo, MD. “We also don't know the long-term benefits and harms for children and adolescents who initiate blood pressure medications when they are young. While there is much we don't know, we do know that eating a healthy diet, being active, and maintaining a normal weight are ways children and teens can improve their cardiovascular health."

Study: Tobacco Advertisements Connecting with Young Kids in Many Low-, Middle-income Countries
The global pervasiveness of tobacco advertisements means that most very young children in many low-and middle-income countries are familiar with cigarette brands, and nearly 70 percent of kids ages 5 and 6 can identify at least one cigarette logo, according to a new study in the journal Pediatrics. The study is from the Institute for Global Tobacco Control at the Johns Hopkins Bloomberg School of Public Health. The findings demonstrate the significant steps countries and public health organizations still need to take to limit the influence of tobacco ads. “Evidence-based strategies exist to reduce the ability of tobacco companies to market their products to children, such as implementing and enforcing bans on tobacco advertising, promotion and sponsorship,” said Joanna Cohen, PhD, co-author of the study and director on the institute. “Putting large picture warnings on the front and back of cigarette packs and requiring plain and standardized packaging, as Australia has done, also helps to reduce the attractiveness of cigarette packs among young children.” Read more on global health.

Study: Improved Layperson CPR Education Increases Bystander Intervention, Saves Lives
As many as 80 percent of cardiac arrests occur outside of a hospital, meaning that improving the layperson’s knowledge of cardiopulmonary resuscitation (CPR) could improve the odds of effective bystander intervention—and along with it the chances of survival, according to a new study in the Journal of the American Medical Association. "In many cases, time from recognition of cardiac arrest to the arrival of emergency medical services is long, leaving bystanders in a critical position to potentially influence patient prognosis through intervention before EMS arrival," according to the study. "However, only a minority of cardiac arrests receive bystander CPR." The study authors looked at a 10-year period of about 19,400 out-of-hospital cardiac arrests in Denmark, finding that as the percentage who received bystander CPR rose from about 21 percent to 45 percent, the rate of people who arrived alive to the hospital also rose from about 8 percent to 22 percent.

Post-menopausal Hormone Therapy Ineffective at Long-term Disease Prevention
Post-menopausal hormone therapy is not effective at the long-term prevention of heart disease and other chronic conditions, according to a new study in the Journal of the American Medical Association. The study a review of the Women's Health Initiative (WHI), which is a collection of U.S. trials established to assess the role of hormone therapy in preventing chronic diseases in more than 27,000 healthy, older women. They found that the benefits were minimal and were offset by concerns over complications such as elevated rates of blood clots and strokes. However, the findings do support the continued use of hormone therapy for the short-term treatment of hot flashes, as well as for “relatively younger women who use it for a finite time,” according to HealthDay.

Study: Exercise as Effective as Drugs at Treating Heart Disease
When it comes to treating heart disease, exercise may be just as effective as medication, according to a new study in the British Medical Journal. The researchers from Britain's London School of Economics and Harvard and Stanford universities said this means physical activity should also be included as a comparison during the development and testing of new medications, as the lack of its inclusion "prevents prescribers and their patients from understanding the clinical circumstances where drugs might provide only modest improvement but exercise could yield more profound or sustainable gains." Cardiovascular disease accounts for 17 million global deaths each year. Another recent study also reinforced the ability of exercise to help prevent high blood pressure.

Even Healthy Weight Adults with High Body Fat at Increased Risk of Heart Disease
Even older adults with healthy body weights can be at increased risk of cardiovascular diseases if they have high percentages of body fat, according to a new study The American Journal of Cardiology. "Just because someone has a normal BMI does not necessarily mean they are metabolically normal," said lead researcher Dr. John Batsis, a geriatrician at Dartmouth-Hitchcock Medical Center in Lebanon, New Hampshire. The study found that women with excess body fat (above 35 percent) were 57 percent more likely to die from heart-related causes within 11 years than were women with healthy body fat levels. Javier Salvador, MD, an endocrinologist at the University Clinic of Navarra in Pamplona, Spain, who was not involved in the study, said the findings demonstrate the limits of body mass index (BMI), which measures weight in relation to height.

‘Image Discrepancies’ of Job Roles Can Hurt Job Satisfaction, Performance and Pay
The lack of client understanding of the actual job roles of nurse practitioners and other professionals can negatively impact job satisfaction, performance and pay, according to a recent study in the Academy of Management Journal. "If people don't understand what you do, they tend to devalue what you do," study co-author Michael Pratt, a professor of management and organization at Boston College. "They don't understand why you're making all this money—'Why should I pay you all this money?' is a common question these professionals keep hearing." The study looked at “image discrepancies” in four professions—nurse practitioners, architects, litigation attorneys and certified public accountants—finding a noticeable and negative lack of understanding by clients for each. For example, many patients don’t realize that nurse practitioners can examine patients and prescribe medicine, and instead insist on seeing a doctor. "I assumed professionals would actually get over it, that there would be frustration, it would be an interpersonal problem, and that would be the extent of it," Pratt said. "I didn't think it would have such a big impact on how they did their job, how it affected their pay and how they performed. I was surprised at the depth of how this affected job performance. It's not simply annoying -- it has real impact.” Read more on mental health.

CDC Emphasizing Electronic Laboratory Reporting to Improve Public Health’s Response to Disease Outbreaks
The U.S. Centers for Disease Control and Prevention’s (CDC) emphasis on the widespread adoption of electronic laboratory reporting (ELR) has helped improve public health’s response to dangerous infections, according to data from CDC’s Morbidity and Mortality Weekly Report (MMWR). ELRs enable labs to report disease outbreak information quickly and in a usable format. The number of labs that utilize ELRs has more than doubled since 2005, and CDC has helped fund their increased use since 2010 in 57 state, local and territorial health departments. Current estimates are that about 62 percent of lab reports were received electronically. “Electronic laboratory reporting can give health officials better, more timely and complete information on emerging infections and outbreaks than they have ever received before,” said Robert Pinner, MD, associate director for surveillance, programs and informatics in CDC’s National Center for Emerging and Zoonotic Diseases. “Implementing these systems is a complex task that requires substantial investment, but ELR will provide health departments the tools they need to quickly identify and respond to disease threats and monitor disease trends now and in the future.” Read more on technology.
