Financial Incentives Double Smoking Quit Rates
Offering small financial incentives doubles smoking cessation rates among low-income smokers, according to research from The University of Texas Health Science Center at Houston. The study was published in the American Journal of Public Health. Participants in the intervention group could earn up to $150 in gift cards over four weeks. Progress was monitored for 12 weeks following the quit date. A control group received only cessation information, no incentives. The researchers found that quit rates were 49 percent for those in the incentive group but only 25 percent in the control group. Read more on tobacco.
Two Thirds of Parents Would Take Kids out of Daycare if Other Children Don’t Have Their Immunizations
A national survey of parents with children ages 0-5 found that three quarters of them would take their children out of daycare if at least one quarter of the children at daycare were not up to date on their vaccines. The researchers say the scenario is realistic since about 25 percent of preschool children in the United States are not fully vaccinated, according to national statistics. Just over 40 percent of survey responders also said that children missing vaccines should be asked to leave daycare until they are up to date. Read more on vaccines.
Three Drugs During Pregnancy Better Than Current Complicated Regimen for Preventing Mother-to-Baby HIV Transmission
For HIV-infected women in good immune health, taking a three-drug regimen during pregnancy prevents mother-to-child HIV transmission more effectively than taking one drug during pregnancy, another during labor and two more after giving birth, according to a new study funded by the National Institutes of Health.

Allergic to Eggs? You Can Safety Get the Flu Shot—and Other Life-Threatening Allergy and Asthma Myths
Major medical conferences often showcase a study, perhaps two, that can change the field of practice and the health for thousands to millions. At this year’s annual meeting of the American College of Allergy, Asthma and Immunology, four studies made such an impact that the College created an infographic to better help share the findings:
- Many—perhaps even most—people who think they’re allergic to penicillin really aren’t. And taking alternative antibiotics can cost more, be less effective and bring side effects.
- A study in Chicago found that stocking epinephrine pens in public schools saved lives for more than a dozen kids who had potentially fatal allergic reactions, but who hadn’t been told to carry their own pen. The researchers say the lesson learned is that more schools and other public spaces need to keep supplies of the low-cost devices on hand.
- Many doctors don’t keep up with the most recent allergy information—which means their patients may not be getting the most effective treatment. For example, 85 percent of internists polled think an egg allergy is a contraindication for the flu shot. Evidence shows the shot to be safe for people with an egg allergy.
- Some YouTube asthma videos promote incorrect and dangerous alternative treatments for asthma that pose a risk of death if used rather than treatment based on clinical trials and scientific evidence.
Flu season in the United States typically runs from November through March, with the peak coming in January and February. But people can catch the flu both earlier than the usual start time and after the usual end of the season. In addition, the severity of the flu season can vary with from 3,000 to 49,000 U.S. deaths in a given year, an average of more than 200,000 hospitalizations and millions of illnesses, according to the U.S. Centers for Disease Control and Prevention (CDC).
Flu shot season has a shorter time table, so many pharmacies and doctors’ office that are well stocked at the moment can run out before Christmas, making it difficult for people who put off their vaccinations to find a vaccine location and protect themselves.
And despite a yearly campaign to get people to roll their arms up, less fewer than half of adults and less than 60 percent of kids received a flu shot last year. NewPublicHealth recently spoke with Carolyn Bridges, MD, the CDC’s associate director for adult immunizations about what keeps people from getting the flu shot and how more people can be encouraged to get the vaccine.
NewPublicHealth: What is it that keeps people from getting the shot?
Carolyn Bridges: I think there are a number of things. Certainly, we have pretty good awareness about the recommendations for the influenza vaccine, although some people may just not realize that they are potentially at risk. The current recommendations call for all persons six months of age and older to get an annual flu vaccine, with rare exceptions. But the vaccine recommendations have changed over time and in the last few years have been broadened to include [just about] everyone. For some people the message hasn’t gotten to them that in fact they are now included in the group recommended for a yearly flu vaccine
NPH: What common misconceptions do people still have about the flu vaccine?
Bridges: In terms of the safety, some people question or are worried about getting the flu from the flu vaccine. That’s still a common comment that we receive. Sometimes people will certainly have body aches or some tenderness in the arm where they get their flu vaccine, but that’s certainly not the same as getting influenza, and those symptoms generally are very self-limited and go away within two to three days. But the flu vaccine cannot cause the flu.
EBOLA UPDATE: WHO Officials See ‘Glimmers of Hope’ in Liberia as New Case Rate Declines
(NewPublicHealth is monitoring the public health crisis in West Africa.)
There are “glimmers of hope” in Liberia as officials from the World Health Organization (WHO) say the rate of new Ebola cases appears to be declining for the first time since the outbreak began. Still, an official with the global health agency said they are still very much concerned and on guard. “It’s like saying your pet tiger is under control,” said Bruce Aylward, the WHO’s assistant director-general in charge of the operational response, according to The Washington Post. “This is a very, very dangerous disease” and “the danger now is that instead of a steady downward trend we end up with an oscillating trend where the virus goes up and down” because areas become reinfected.

Study: Infant’s Birthweight Tied to Disease Risk Later in Life
An infant’s size at birth may help predict their health later in life, with babies who are heavier have less of a risk for future disease, according to a new study in The FASEB Journal. Researchers based their findings on an analysis of cord blood of newborn babies from mothers with raised glucose levels during late pregnancy and blood taken later. "These findings support the hypothesis that common long-term variation in the activity of genes established in the womb may underpin links between size at birth and risk for adult disease," said Claire R. Quilter, Ph.D., study author from the Mammalian Molecular Genetics Group, Department of Pathology at the University of Cambridge in the United Kingdom. "If confirmed these could be important markers of optimal fetal growth and may be the first step along a path to very early disease prevention in the womb." Read more on maternal and infant health.
FDA Approves New Meningitis Vaccines
The U.S. Food and Drug Administration (FDA) has approved the first vaccine approved to prevent invasive meningococcal disease in the United States. The drug is to prevent Neisseria meningitidis serogroup B is approved for individuals ages 10 to 25 years. Approximately 500 total cases of meningococcal disease were reported in the United States in 2012, with 160 having been causes by serogroup B. “Recent outbreaks of serogroup B Meningococcal disease on a few college campuses have heightened concerns for this potentially deadly disease,” said Karen Midthun, MD, director of the FDA’s Center for Biologics Evaluation and Research, in a release. “The FDA’s approval of Trumenba provides a safe and effective way to help prevent this disease in the United States.” Read more on vaccines.
EBOLA UPDATE: WHO Plans on Ebola Vaccine Tests in January
(NewPublicHealth is monitoring the public health crisis in West Africa.)
The World Health Organization plans to begin testing two experimental Ebola vaccines in West Africa by January. The vaccines will likely be tested on more than 20,000 frontline health care workers and others in the region. The global health agency also announced that a blood serum treatment could be available for use in Liberia within two weeks. Read more on Ebola.
Study: Automated Tracking Improves Vaccine Compliance in Health Care Workers
Automated tracking of influenza vaccinations increases vaccination compliance in health care personnel while also reducing the workload burden on human resources and occupational health staff, according to a new study in the journal Infection Control and Hospital Epidemiology. Researchers analyzed data on nearly 7,000 people including in a mandatory vaccination program, finding that “automated reminders and tracking accounted for more than 98 percent of compliance among healthcare personnel.” "Mandatory vaccination programs help protect vulnerable patients, but can be tremendously time and resource dependent," said Susan Huang, MD, MPH, an author of the study, in a release. "By successfully automating a system to track and provide feedback to healthcare personnel who have not received their seasonal flu vaccine, we are providing safer places for care and reducing the administrative burden of our mandatory vaccination program."

Study: Living with a Smoker is as Bad as Living in a Highly Polluted City
Living with a smoker is the same as living in a smoke-free home in a heavily polluted city such as Beijing or London, with the non-smokers exposed to three times the World Health Organization’s officially recommend safe levels of damaging air particles, according to a new study in the journal Tobacco Control. In a collection of four studies, researchers determined that the concentration of fine particulate matter was approximately 10 times higher in smoking homes than it was in non-smoking homes. “Smokers often express the view that outdoor air pollution is just as much a concern as the second-hand smoke in their home,” said Sean Semple, MD, of University of Aberdeen, in a release. “These measurements show that second-hand tobacco smoke can produce very high levels of toxic particles in your home: much higher than anything experienced outside in most towns and cities in the UK. Making your home smoke-free is the most effective way of dramatically reducing the amount of damaging fine particles you inhale.” Read more on air quality.
WHO: 20,000 Could Be Infected Before Ebola is Under Control
The World Health Organization (WHO) now estimates that the ongoing Ebola outbreak in West Africa could infect as many as 20,000 people before public health officials are able to get it under control. The latest numbers on the disease place the number of infected at 3,069, with 1,552 deaths. Also yesterday, an article in the journal Science reported that the virus has mutated repeatedly during the outbreak, making it even more difficult to manage. Five of the report’s 50 co-authors have died of Ebola. Read more on Ebola.
CDC: Majority of Parents Have their Children Vaccinated
The majority of parents have their children receive routinely recommended vaccinations, according to the latest Morbidity and Mortality Report from the U.S. Centers for Disease Control and Prevention. The report found that in 2013:
- More than 90 percent of babies were vaccinated against measles, mumps, and rubella (MMR); poliovirus; hepatitis B; and varicella
- 73 percent were vaccinated against rotavirus
- 83 percent were vaccinated against Hepatitis A
- 74 percent were vaccinated against Hepatitis B
- Less than 1 percent of children received no vaccines
“I want to personally recognize the hard work of doctors and nurses coping with many challenges in the course of clinical work, and commend parents who, despite competing responsibilities, continue to prioritize immunization to keep their children healthy and safe,” said Anne Schuchat, MD, director of the National Center for Immunization and Respiratory Diseases. “These people are central in keeping young children healthy by ensuring they receive the recommended vaccines on schedule.” Read more on vaccines.
Study: Conflict Between Parents Also Causes Conflict with Children
Conflict between parents in a marriage also has a negative impact on parents’ relationships with their children, according to a new study in the Journal of Family Psychology. Researchers had parents in more than 200 families write daily diary entries for 15 days, then had each parent rate the quality of both their marriage and their relationships with their kids. They found that days with conflict between parents also had increased cases of problems between the parents and their children. "We see from the findings that the marriage is a hub relationship for the family. The quality of that relationship spills over into each parent's interactions with the child. So if mom and dad are fighting, it will show up initially—and in some cases on the second day—in a poorer quality relationship with their kids,” said study author Chrystyna Kouros, an assistant professor in the psychology department at Southern Methodist University, Dallas, in a university news release.

EBOLA UPDATE: Looted Quarantine Center Raises Fears of Ebola’s Spread
(NewPublicHealth is monitoring the public health crisis in West Africa.)
The raid by residents of an Ebola quarantine center in Liberia this weekend sent potentially infected patients fleeing and has raised very serious concerns over spreading the outbreak throughout West Point, Monrovia. Looters—apparently angry that patients were brought to the holding center from other parts of Monrovia—were seen taking items that were visibly stained with blood, vomit and excrement, all of which can spread the Ebola virus. The Washington Post reports that there have been talks about quarantining the entire township if needed. Read more on Ebola.
Study: Mothers in Poorer Health Less Likely to Breastfeed
Mothers who are in poorer health are also less likely to breastfeed their infant children, according to a new study in the journal PLOS ONE. Researchers from the School of Public Health at the University of Minnesota determined that women who are obese, have diabetes or have hypertension were 30 percent less likely to intend to breastfeed than were mothers without health complications. “Statistically we’re seeing an increase in breastfeeding in the U.S., which is great news. Unfortunately, at the same time, rates of obesity and other health problems are increasing. More than a million women each year enter pregnancy with a health problem, and our study shows that these mothers were less likely to plan to breastfeed,” said Katy Kozhimannil, PhD, lead author of the study and assistant professor at the university, in a release. “This is troubling because the families with social and medical risk factors are often those who stand to gain the most benefits from breastfeeding.” Read more on maternal and infant health.
Study: HPV Vaccine Still Effective After Eight Years
The human papillomavirus (HPV) vaccine appears to remain effective at protecting against the sexually transmitted virus for at least eight years, according to a new study in the journal Pediatrics. Researchers randomly assigned 1,781 sexually inactive boys and girls ages 9-15 to either the HPV vaccine or placebo shots, finding that those who received the vaccine still had antibodies against HPV after eight years. “The body's response against HPV by making antibodies looks very good at eight years, and it seems like no booster doses will be necessary," said lead researcher Daron Ferris, MD, director of the HPV epidemiology and prevention program at Georgia Regents University in Atlanta, according to HealthDay. "These are all indications that the vaccine is safe, and it looks like it's effective in preventing genital warts and other diseases caused by HPV.” Read more on vaccines.
The National Institute of Allergy and Infectious Diseases (NIAID), a division of the National Institutes of Health, is set to begin an early-stage clinical trial for a vaccine to protect against the Ebola virus. The trial should begin as early as September. The vaccine to be tested was developed by the NIAID’s Group Health Research Center in Seattle and does not contain infectious Ebola virus material. Instead, it’s what is known as an adenovirus vector vaccine containing an insert of two Ebola genes. The vaccine works by entering a cell and delivering the new genetic material, causing a protein expression that activates an immune response in the body. Researchers have seen success with studies in primates.
The vaccine being tested is not the experimental serum that was used on two Ebola-infected health workers recently evacuated from Liberia. In those cases, Samaritan’s Purse, the aid organization that sent the health workers to Africa, contacted officials from the U.S. Centers for Disease Control and Prevention (CDC) in Liberia to discuss the status of various experimental treatments they had identified through a medical literature search. CDC officials referred them to an NIH scientist in West Africa familiar with experimental treatment candidates who was then able to refer them to pharmaceutical companies working on experimental treatments. The serum being used is made by Mapp Biopharmaceutical of San Diego, Calif.

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.
FDA: Sunlamps to Require Health Warnings
The U.S. Food and Drug Administration (FDA) has issued a final order that requires sunlamp products and ultraviolent (UV) lamps for use in sunlamp products to carry warnings stating that they should not be used by people under the age of 18. The order reclassifies the products from low-risk (class I) to moderate-risk (II). “The FDA has taken an important step today to address the risk to public health from sunlamp products,” said Jeffrey Shuren, MD, director of the FDA’s Center for Devices and Radiological Health, in a release. “Repeated UV exposure from sunlamp products poses a risk of skin cancer for all users—but the highest risk for skin cancer is in young persons under the age of 18 and people with a family history of skin cancer.” People who are exposed to UV radiation as a result of indoor tanning increase their risk of melanoma by 59 percent, according to the American Academy of Dermatology.

CDC: U.S. Measles Cases at a 20-year High
Cases of measles in the United States are at a 20-year high, with international travel by unvaccinated people a major contributor, according to the U.S. Centers for Disease Control and Prevention (CDC). The CDC reports that there were 288 U.S. cases between January 1 and May 23 this year—and 97 percent were associated with importation by travelers from at least 18 countries. Approximately 90 percent of the cases were in people who were not vaccinated or whose vaccination status was unknown. “The current increase in measles cases is being driven by unvaccinated people, primarily U.S. residents, who got measles in other countries, brought the virus back to the United States and spread to others in communities where many people are not vaccinated,” said Anne Schuchat, MD, assistant surgeon general and director of CDC’s National Center for Immunizations and Respiratory Diseases, in a release. “Many of the clusters in the U.S. began following travel to the Philippines where a large outbreak has been occurring since October 2013.” Read more on vaccines.
Type of Increased Heart Risk Depends on Which Blood Pressure Number is High
The type of increased heart risk a person with high blood pressure faces depends on which number in their blood pressure—the top, which is systolic, or the bottom, which is diastolic—is high, according to a new study in The Lancet. Researchers analyzed health care date on more than 1 million people ages 30 and older in England, finding that people with higher systolic blood pressure had a greater risk of bleeding strokes and stable angina, while people with higher diastolic blood pressure were more likely to be diagnosed with an abdominal aortic aneurysm. In addition, they found that a 30-year-old with high blood pressure has a 63 percent lifetime risk of developing heart disease, compared with 46 percent for a person with normal blood pressure. "With lifetime risks this high, the need for new blood pressure-lowering strategies is paramount," said lead investigator Eleni Rapsomaniki, MD, from The Farr Institute for Health Informatics Research in London, England, in release.
