Even as the global population continues to grow, technological and societal advances mean that our world is constantly getting smaller. Or at least that we are becoming more interconnected.
Understanding this—that a person in a Midwestern U.S. state is better off when a person on the other side of the world has access to quality health care—the U.S. Department of Health and Human Services’ (HHS) Global Health Strategy is working with partners across the globe to improve the health of everyone.
"Although the chief mission of [HHS] is to enhance the health and well being of Americans, it is critically important that we cooperate with other nations and international organizations to reduce the risks of disease, disability, and premature death throughout the world," said HHS Secretary Kathleen Sebelius.
One of the most powerful initiatives has been the push toward greater immunization rates. Immunizations alone saved 3 million children’s lives in 2011. Over the past decade, premature deaths from measles have been cut by 71 percent and from tetanus by more than 90 percent. And polio is closer and closer to complete eradication.
Still, vaccine-preventable diseases still account for approximately one in four global deaths of children under the age of 5. And of the 22 million children who go without the full benefits of vaccines each year, it is often the poorest that are most affected.
Among the greatest continuing obstacles are the persistent myths surrounding vaccinations, such as the false and repeatedly debunked belief that they cause autism.
“Overcoming these mistaken beliefs has become an integral part of our work towards global vaccine access. Until we reach the day when no lives are lost to vaccine-preventable diseases, we will aggressively continue to develop new and improved vaccines and ensure they are available to everyone in every country.”

MERS Unlikely to Cause Pandemic; Global Cooperation Still Needed
Middle East respiratory syndrome (MERS), which emerged last year in Saudi Arabia, was compared to severe acute respiratory syndrome (SARS) and found to be less infectious, in a new study published in The Lancet Infectious Diseases. The study examined the question of whether MERS has the potential to cause a pandemic, and how quickly. The study authors concluded that MERS does not yet have pandemic potential, and in fact appears to be less infectious than SARS. There have been 81 laboratory-confirmed cases of MERS infections, 45 of which were fatal. MERS is more likely to affect older men with chronic disease, and were most often transmitted in health care settings—but unlike SARS, the virus was less likely to also infect healthy health care workers. Researchers call for healthcare facilities to prepare to provide safe care for patients with acute respiratory infections, and take measures to help prevent the spread of the disease.

CDC: HPV Vaccination Rates for Adolescent Girls Remain Stagnant
Just over half (53.8%) of girls age 13-17 years old received the human papilloma virus (HPV) vaccine in 2012, with no increase over the rate in 2011. Since 2006, the Advisory Committee on Immunization Practices has recommended routine vaccination of adolescent girls at ages 11 or 12 years with 3 doses of HPV vaccine. HPV causes 70 percent of cervical cancers. If HPV vaccine had been offered during healthcare visits when girls were already in the office to get a different vaccine, HPV vaccination coverage could have reached 90 percent. Approximately 79 million persons in the United States are infected with HPV, and approximately 14 million will become newly infected each year. Each year, 26,000 new cases of cancer are diagnosed that can be traced back to HPV infection. Read more on vaccines.
New Breathalyzer-like Device Tells You If Your Workout is Working
New technology being prototyped in Japan measures how well you're burning body fat and help you gauge the success of your diet and exercise program, using a smartphone and pocket-sized, bluetooth enabled device. The device measures exhaled breath for acetone, a metabolite produced from fat burning. The researchers tested the device in 17 healthy men and women, reporting their findings online July 25 in the Journal of Breath Research, and finding that the device was as effective as more established "gold standard" measures. Further research is needed on larger, more diverse populations, but if it pans out, "Enabling users to monitor the state of fat burning could play a pivotal role in daily diet management," Hiyama said in a journal news release.

Study: Pertussis Booster Only ‘Moderately’ Effective
The “booster” vaccine for pertussis—or whooping cough—is only “moderately” effective in preventing the disease in adolescents and adults, according to a new study in the journal BMJ. The Kaiser Permanente-backed study, which is the first to look at the effectiveness of the Tdap booster shot in the new generation that has only received acellular vaccines, found the effectiveness to be between 53 and 64 percent. This indicates that additional vaccinations may be required to adequately prevent outbreaks according to lead author Roger Baxter, MD, co-director of the Kaiser Permanente Vaccine Study Center. The state of California saw its highest number of cases of pertussis in more than 60 years in 2010, when it had more than 9,000 cases that led to 809 hospitalizations and 10 deaths, according to the National Center for Biotechnology Information.

NYC Hospitals Prescribing Fruits, Vegetables to At-risk Youth
An apple a day to keep the doctor away? At two New York City hospitals, you can get a prescription for just that. Under a four-month pilot program, doctors at Lincoln Medical Center in the Bronx and Harlem Hospital are giving prescriptions for fruits and vegetables to at-risk youths. The kids and their families receive coupons which can be redeemed for product at local farmers markets and city green carts. “This is probably going to prevent an awful lot more disease over the long-term than a lot of the medicines we tend to write for,” said New York City Health Commissioner Thomas Farley, MD, said Tuesday in the green market outside Lincoln Medical Center.

Breast Cancer Survival Times Shorter for Black Women
The fact that black women receive less health care overall than their white counterparts, combined with the lack of early screening and detection programs in many black communities, means they live an average of three fewer years with a breast cancer diagnosis, according to a new study in The Journal of the American Medical Association. Researchers at the University of Pennsylvania found that black women were less likely to receive an early diagnosis when the cancer was more treatable; they also found that quality of care was in general lower, though not enough to explain the survival gap. Data showed that 70 percent of white women lived at least five years after a breast cancer diagnosis, compared to 56 percent of black women. “Something is going wrong,” said Jeffrey H. Silber, MD, a professor at the University of Pennsylvania and the director of the Center for Outcomes Research at the Children’s Hospital of Philadelphia, which studies disparities in health care. “These are huge differences. We are getting there too late. That’s why we are seeing these differences in survival.” Read more on cancer.
The decision by the ABC Network to hire former model and MTV celebrity Jenny McCarthy to be a host on “The View,” a weekday talk show aimed at women, had vaccines in the news this week. It remains to be seen whether the increased attention will have an impact on the number of kids getting their shots, and getting them on time this year. In her book and in a myriad of interviews, McCarthy has linked her son’s diagnosis of autism with the Measles/Mumps/Rubella (MMR) vaccines he received as a baby. In a 2008 USA TODAY/Gallup Poll, a quarter of people surveyed said they were familiar with McCarthy’s views and of those respondents, 40 percent said her views would make them more likely to question the safety of vaccines.
As parents start setting up back to school visits, including many immunizations, for kids, Kristine Sheedy, PhD, associate director of communication science at the Centers for Disease Control and Prevention (CDC) National Center for Immunization and Respiratory Diseases, answered questions for NewPublicHealth about the impact of parents skipping or delaying childhood vaccines.
NewPublicHealth: What are the most common vaccines parents skip for their kids, and why?
Kristine Sheedy: We know that parents and health care professionals across the U.S. are doing a good job protecting babies and young children from vaccine-preventable diseases because data from our 2011 National Immunization Survey (NIS) shows immunization coverage among children 19 to 35 months remained stable or increased for all recommended vaccines. In fact, coverage for most of the routine vaccines remains at or over 90 percent, and less than 1 percent of young children get no vaccinations.
While immunizations are a ubiquitous symbol of public health, in the last decade or so many public health departments have shied away from using the icon on their home pages or even adding it to a top ten list of what they do in the hopes of making both citizens and policymakers realize that public health extends far beyond infectious disease. Yet as public health departments integrate their work with the private sector, who will do the vaccinating, how immunization records will be kept and who gets paid for the work are pivotal issues that local health officials are grappling with.
A well-attended session at the NACCHO Annual conference yesterday provided a few more questions than answers, but armed attendees with new information as implementation of the Affordable Care Act (ACA) begins and both public health and private providers see their roles change and merge. Significantly, the ACA is expected to enroll millions of children, and under new rules the Vaccines for Children program will no longer cover the cost for vaccines for children who can receive immunizations under their own insurance. That will reduce funding for some health departments.
Other changes ahead for vaccination coordination include the role of accountable care organizations (ACOs) in coordinating care under the ACA, electronic registries and billing for public health services, said Paul Etkind, MPH, DrPH, head of infectious diseases at NACCHO.
“Much of this has yet to play out, so there are many unknowns,” said Etkind, who added that vaccines are a good example of the need for up front conversations with providers about what public health has to offer and a good way for health departments to become part of ACOs. “Going forward there will be a greater emphasis on coordinating care between the public and private sectors, than in delivering the care in many cases and public health needs to be active players in this process.”
Percentage of Single-father Households Up Dramatically
In 1960 only about 1 percent of households with children under the age of 18 were headed by single fathers. Today that number is a record 8 percent, or about 2.6 million in 2011. About one quarter of all single-parent households are headed by fathers. The climb in single fathers is due to largely the same reason as the climb in single mothers, according to data from Pew Research Trends. These include a dramatic increase in non-marital births and high divorce rates. However, there are notable differences between households headed by a single father or a single mother, with perhaps the greatest being that single fathers are generally better off financially.

One in Seven Skin Cancer Patients Returns to Tanning Booth
Even after being diagnosed with skin cancer, one in seven people who use indoor tanning will return to a tanning booth within the next year, according to a new study in JAMA Dermatology. Research consistently shows that indoor tanning, which can emit up to 15 times the ultraviolet A radiation of the sun, dramatically increases the risk of cancer. "The situation may be analogous to that of lung cancer patients who continue to smoke after diagnosis," said study author Brenda Cartmel, a cancer prevention researcher at the Yale School of Public Health in New Haven, Conn., to Reuters. "Just as tobacco is known to be addictive, our research suggests that some patients may become dependent on tanning, with new intervention approaches needed to change these behaviors." About 20 million American visit tanning beds each year; the majority of them are young white women. Read more on cancer.
Majority of OB/GYNs Do Not Follow Guidelines on Cervical Cancer Prevention
Fewer than one-third of U.S. obstetricians-gynecologists vaccinate eligible patients against HPV and only about half follow the guidelines for cervical cancer prevention, according to a new study in the American Journal of Preventive Medicine. The American Congress of Obstetricians and Gynecologists recommend Pap tests beginning at the age of 21 and then gradually decreasing the rate of testing, depending on patient age and history. "In the current survey and others, providers stated that the largest barrier to HPV vaccination was patients and parents declining to receive the vaccine," said lead investigator Rebecca Perkins, MD, of the Boston University School of Medicine, in a release. "However, studies indicate that most patients support HPV vaccination, and that a strong physician recommendation is the most important determinant of vaccine uptake in young women."

HPV Vaccine Has Lowered HPV Infection Rates in Teen Girls
A new study published in The Journal of Infectious Diseases has found that since the HPV vaccine was introduced in 2006, vaccine-type HPV prevalence decreased 56 percent among female teenagers 14-19. About 79 million Americans—most in their late teens and early 20s—are infected with HPV. Each year, about 14 million people become newly infected. According to the U.S. Centers for Disease Control and Prevention (CDC), each year in the United States about 19,000 cancers caused by HPV occur in women, with cervical cancer the most common. About 8,000 cancers caused by HPV occur each year in men in the United States, with oropharyngeal (throat) cancers the most common. “This report shows that the HPV vaccine works well, and the report should be a wake-up call to our nation to protect the next generation by increasing HPV vaccination rates,” said CDC Director Tom Frieden, MD, MPH. “Unfortunately only one third of girls aged 13-17 have been fully vaccinated with HPV vaccine.” Routine vaccination at age 11-12 for both boys and girls is recommended in the US, but according to recent national immunization surveys, only about half of all girls in the United States and far fewer boys, have received the first dose of HPV vaccine.

AMA Announces New Policy Aimed at Removing Sugared-Beverages from SNAP Program
The American Medical Association (AMA) passed a policy at its annual meeting yesterday calling on the association to work to remove sugar-sweetened beverages from the SNAP (Supplemental Nutrition Assistance Program) for low-income families. SNAP replaced the U.S. Food Stamp program several years ago. The new policy also encourages state health agencies to include nutrition information in routine materials sent to SNAP recipients. According to the AMA, 58 percent of beverages bought with SNAP dollars are sugar-sweetened ones. The AMA also passed a resolution recognizing obesity as a disease “requiring a range of medical interventions to advance obesity treatment and prevention.” “Recognizing obesity as a disease will help change the way the medical community tackles this complex issue that affects approximately one in three Americans,” said AMA board member Patrice Harris, MD.

HUD Releases First-Ever Same Sex Housing Discrimination Study
The U.S. Department of Housing and Urban Development (HUD) has released the nation’s first-ever national study examining housing discrimination against same-sex couples in the private rental market. The study found that same-sex couples experience unequal treatment more often than heterosexual couples when responding to internet ads for rental units, and that gay male couples experience more discrimination than lesbian couples. “A person’s sexual orientation or gender identity should not be a reason to receive unfavorable treatment when searching for housing,” said Bryan Greene, HUD Acting Assistant Secretary for Fair Housing and Equal Opportunity. “HUD is committed to making sure that LGBT individuals have equal access to housing opportunities.” HUD’s study is based on nearly 7,000 email tests conducted in 50 metropolitan markets across the country between June and October of 2011. For each paired test, two emails were sent to the housing provider regarding the unit advertised online. The only difference between the emails was whether the couple was same-sex or heterosexual. Unfavorable treatment was measured by whether the tester was told the unit was available, asked to contact the landlord, invited to the see the apartment, or received any response at all.

HHS Updates Guidelines to Prevention Disease Transmission from Organ Transplants
The U.S. Department of Health and Human Services (HHS) has updated its guidelines on reducing unexpected disease transmission through organ transplantation. The 2013 PHS Guideline for Reducing Human Immunodeficiency Virus, Hepatitis B Virus and Hepatitis C Virus Transmission through Organ Transplantation updates the 1994 U.S. Public Health Service guidelines designed to improve patient safety. The recommendations include additional screening, revised risk factors and more sensitive laboratory testing. “Transmission of infections through organ transplants is a critical concern for patients, their families and healthcare personnel involved in transplant procedures,” said HHS Assistant Secretary for Health Howard K. Koh, MD, MPH. “Putting these new recommendations into practice will allow doctors and patients to make better, more informed decisions when accepting organs for transplantation.” Read more on prevention.
HUD: $40M in Housing Counseling Grants to Improve Choices, Opportunities
The U.S. Department of Housing and Urban Development (HUD) is providing $40 million in housing counseling grants to help people find housing, to make more informed choices and to improve their ability to keep their existing homes. The grants will help more than 1.6 million households via 334 national, regional and local organizations. “Make no mistake: these grants will do a lot of good,” said HUD Secretary Shaun Donovan in a release. “The evidence is clear that housing counseling works. These grants are a smart investment to help families and individuals find and keep housing which helps promote neighborhood stability in the long term.” Read more on housing.
Majority of Adults Unaware of their Whooping Cough Vaccination Status
As the number of U.S. cases of pertussis—or whooping cough—rises, many adults are completely unaware of their need to remain up to date on their vaccinations. Only 20 percent say they’ve received the vaccine within the past decade and more than 60 percent do not even know their vaccination status. The lack of adult vaccinations can increase transmission rates to children; the majority of whooping cough deaths are children younger than 3 months. "Teens and adults who have received the [whooping cough] vaccine are less likely to get whooping cough themselves, and therefore less likely to spread whooping cough to other people, including infants who have not yet been protected by the recommended [whooping cough] vaccinations," said Matthew Davis, MD, director of the new University of Michigan National Poll on Children's Health.

Mammography Rates Remained Steady After Change in Guidelines
The proportion of women undergoing screening for breast cancer every year did not change after U.S. Preventive Services Task Force released recommendations saying there wasn't enough evidence to support routine mammograms for women in their 40s, according to a new study published in the journal Cancer. In 2009, the Task Force changed their recommendations to state that women aged 50 to 74 should have a mammogram every other year, and screenings for women under age 50 should be evaluated by each woman with her doctor, according to individual risk factors. "When there are conflicting versions of guidelines, providers may err on the side of screening," said David Howard, a health policy researcher from Emory University in Atlanta, in an interview with Reuters.

Latest HIV Vaccine Study Halted
The National Institutes of Health halted a study testing an experimental HIV vaccine after an independent review board found the vaccine did not prevent HIV infection and did not reduce the amount of HIV in the blood. The trial, started in 2009, is the latest in a series of failed HIV vaccine trials, according to Reuters. The halted study included more than 2,500 volunteers in 19 U.S. cities. Study populations included men who have sex with men and transgender people who have sex with men. Read more on HIV.
CDC's Food Safety Report Card: Some Foodborne Illnesses Spiked in 2012
The Centers for Disease Control and Prevention (CDC) recently released the "nation’s annual food safety report card," and it shows that 2012 rates of infections from two types of foodborne bacteria—campylobacter and Vibrio—have increased significantly when compared to a baseline period of 2006-2008, while rates of most others have not changed during the same period. The data are part of the Foodborne Diseases Active Surveillance Network report. Campylobacter infections have been linked to tranmission in many foods, including poultry, raw milk and produce. These infections were at their highest level since 2000, up 14 percent since 2006-2008. Vibrio infections, often associated with raw shellfish, were up 43 percent.
“The U.S. food supply remains one of the safest in the world,” said CDC Director Tom Frieden, MD, MPH. “However, some foodborne diseases continue to pose a challenge. We have the ability, through investments in emerging technologies, to identify outbreaks even more quickly and implement interventions even faster to protect people from the dangers posed by contaminated food.” Read more on food safety.
Small Amounts of Daily Exercise Can Help Teens Quit Smoking
As little as 30 minutes of daily exercise can help kids quit smoking, according to a new study in the Journal of Adolescent Health. It can also help to reduce tobacco use. Researchers found that daily smokers were more likely to reduce or quit smoking if they combined a fitness program with a smoking cessation program, rather than just a cessation program alone. Every teen in the study smoked an average of half a pack of cigarettes each weekday and a full pack a day on weekends. And that was just one of the poor health habits of many of the participants. "It is not unusual for teenage smokers to engage in other unhealthy habits,” said author Kimberly Horn, associate dean for research at the George Washington University School of Public Health and Health Services. “Smoking and physical inactivity, for instance, often go hand in hand.” According to the U.S. Centers for Disease Control and Prevention, about 13 percent of Americans age 18 and under smoke tobacco.

Study: Low Food Security, Exposure to Violence Closely Linked
There is a close correlation between low food security and exposure to violence, according to a new study in Public Health Nutrition. Researchers spoke with forty-four mothers of children age 3 and under who participated in public assistance programs, finding increased exposure to violence, which in turn increased the chance of negative mental health, an inability to continue school and an inability to make a living wage. The violence included child abuse, neglect and rape. The study clearly demonstrates the need to consider and include violence prevention efforts when establishing policies to deal with hunger.

Size of Parents’ Social Groups Can Affect Whether Kids are Vaccinated
What they hear from friends and the people in their social group may affect whether parents have their children vaccinated, according to a new study in the journal Pediatrics. Parents who were less likely to vaccinate were also more likely to have large social groups and rely on books, pamphlets and the Internet for information on vaccines. "I think that what needs to be done is that everybody needs to understand the importance of vaccines,” said Joseph Anthony Bocchini, Jr., MD, chairman of Pediatrics Medicine at Louisiana State University Health Sciences Center in Shreveport. “And they're not only important for the people who receive them but they're also important for the community." About 95 percent of kindergarten-aged children are appropriately vaccinated, according to the U.S. Centers for Disease Control and Prevention. Read more on vaccines.
