AURORA, Colo. – While adults make up 95 percent of those who die annually from vaccine preventable diseases, a new study from the University of Colorado School of Medicine shows their vaccination rates remain stubbornly low, representing a growing public health concern.

The study, published recently in the Annals of Internal Medicine, is the first to examine several important aspects of adult vaccination. Every year, 30,000 people on average die of vaccine preventable illnesses, almost all of them adult.

"Our study suggests that missed opportunities for adult vaccination are common because vaccination status is not being assessed at every (physician's) visit, which is admittedly an ambitious goal," said Laura Hurley, MD, MPH lead author of the study and an assistant professor of medicine at the CU School of Medicine. "Also, most physicians are not stocking all recommended vaccines."

Recent estimates show only 62 to 65 percent of adults aged 65 and older received a pneumococcal or influenza vaccine respectively; just 20 percent of high risk adults between 19 and 64 received a pneumococcal vaccine and only 16 percent of those 60 and older got their herpes zoster (shingles) vaccination.

Hurley and her fellow researchers designed a national survey of primary care physicians in collaboration with the Centers for Disease Control and Prevention looking at how doctors assessed vaccination status and stocked the 11 recommended adult vaccines in 2012.

"Physicians reported a variety of barriers to vaccine stocking and administration but financial barriers dominated the list," the study said. "Physicians in smaller, private practice often assume more risks from stocking expensive vaccine inventories and may be particularly affected by these financial barriers."

According to Hurley, who also practices at Denver Health, many doctors expressed difficulty getting reimbursed by insurance for vaccines.

For example, the herpes zoster vaccine has been recommended since 2008 but is not widely stocked by physicians. One major reason for this, the study says, is that zoster is covered by Medicare Part D, a pharmaceutical benefit, and physicians report problems with reimbursement. At the same time, the vaccine can require substantial out-of-pocket costs for patients, making it less attractive to them as well.

As a result of these difficulties, many physicians are referring patients to pharmacies or public health facilities for vaccinations.

"The most commonly reported reasons for referring patients elsewhere for vaccines included insurance not covering the vaccine," the study said.

There were also problems coordinating vaccine records when done by someone who is not the patient's primary care physician.

The study makes recommendations for improving the overall situation.

It suggests using Immunization Information Systems or IIS, a confidential database that records all vaccine doses administered by providers in a certain area. The system can allow doctors to know the vaccination status of their patients.

The authors point out that the Affordable Care Act addresses financial barriers to vaccination for privately insured patients by requiring insurers to cover recommended vaccines with no co-pays when delivered by in-network providers. There have also been recommendations for legislative action aimed at making Medicare Part D less of an obstacle to adult vaccinations.

"I feel we need to take a more systematic approach to this issue," Hurley said. "As the population ages this could easily grow into a more serious public health issue."

Statement of Matthew L. Myers, President, Campaign for Tobacco-Free Kids

WASHINGTON, DC – CVS Caremark this week set a powerful example for all retailers, especially those involved in health care, by announcing that it will end the sale of tobacco products at its more than 7,600 stores throughout the United States.

The Campaign for Tobacco-Free Kids applauds CVS for this courageous and historic decision. It represents one of the strongest actions any business has ever taken to address the enormous public health problems caused by tobacco use. CVS’s decision will reduce the availability of cigarettes and other tobacco products and sends an unmistakable message to all Americans, especially children, that tobacco use is uniquely harmful and socially unacceptable.

In making this decision, CVS has recognized that selling tobacco products – the number one cause of preventable death – is fundamentally incompatible with its commitment to improving the health of its customers. We urge other pharmacies and indeed all retailers to quickly follow CVS’s example.

CVS’s decision represents the bold leadership needed from all segments of our society to accelerate progress against tobacco and ultimately end the tobacco epidemic for good. It comes appropriately as the nation marks the 50th anniversary of the first Surgeon General’s report on smoking and health, and just weeks after the latest Surgeon General’s report found that smoking is even more hazardous and takes an even greater toll on the nation’s health.

The Surgeon General reported that smoking kills 480,000 Americans annually, sickens millions more and costs the nation more than $289 billion in health care expenses and other economic costs every year. The latest report also underscored that tobacco use is first and foremost a pediatric epidemic – 90 percent of adult smokers began at or before age 18, and 5.6 million kids alive today will die prematurely from smoking-caused disease unless current trends are reversed. These findings make it increasingly untenable for any responsible business to continue to sell tobacco products.

CVS’s decision adds critical momentum to the strong actions already taken this year to reduce tobacco use, including the release of the new Surgeon General’s report, the continuation of the CDC’s Tips from Former Smokers media campaign that encourages smokers to quit and the launch this week of the FDA’s The Real Cost media campaign aimed at preventing youth from using tobacco.

Together, these actions will help achieve the goals set by the Campaign for Tobacco-Free Kids and six other public health and medical organizations in January: To reduce smoking rates to less than 10 percent within 10 years, protect all Americans from secondhand smoke within five years and ultimately eliminate the death and disease caused by tobacco. CVS’s decision to end tobacco sales will help ensure that it does not take another 50 years to achieve these goals.

About the Academy of Osseointegration

The Academy of Osseointegration is the world’s leading dental implant organization. Founded in 1985, AO provides a focus for the rapidly advancing biotechnology involving the natural bond between bone and certain alloplastic reconstructive materials. The Academy’s primary goal is to advance the field of osseointegrated implants by fostering collaboration between representatives of different dental disciplines—oral surgery, periodontics, prosthodontics and general practice—through clinical and evidence-based research and education. AO membership now exceeds 6,000 professionals in nearly 70 countries.

The study – called TRAP-HPV, an acronym for Transmission Reduction And Prevention with HPV vaccination – is a randomized placebo-controlled double-blind trial involving 500 sexually active couples. The study aims to determine the efficacy of an HPV vaccine in reducing transmission of genital, anal, and oral HPV infection in unvaccinated sexual partners of vaccinated individuals.

HPV is the leading cause of cervical cancer, the second most common cancer in women globally. Prophylactic vaccines against certain high-risk HPV types have been shown to be effective in preventing infection. However, much remains to be understood on the effects of HPV vaccine on the blockage of transmission of target HPV types to sexual partners of vaccinated individuals. 

“This is the first study to look at whether unvaccinated partners of vaccinated individuals have a benefit in terms of protection from HPV infection,” explained Eduardo Franco, Director of the Division of Cancer Epidemiology and leader of the study. “It will help us understand the important issue of herd immunity from HPV vaccination. If partner protection is sufficiently high we may be able to get adequate population level immunity from much less than 100% vaccination coverage and devote our scarce public health funds to other pressing needs.”

“Efficacy studies of the HPV vaccines generally look at genital HPV infections, but our study will also be looking at other anatomical sites that HPV infects, such as the anal and oral regions,” says Kristina Dahlstrom, postdoctoral fellow, Department of Oncology, Division of Cancer Epidemiology. “Increasing the knowledge about HPV transmission dynamics will benefit cost-effectiveness studies and have implications for decision-making when implementing population-level vaccination strategies”.

The U.S. Centers for Disease Control considers HPV the most common sexually transmitted disease in the world. Another McGill study called HITCH (HPV Infection and Transmission in Couples through Heterosexual activity), also from Dr. Franco’s team, found more than half (56 per cent) of young adults in a new sexual relationship were infected with HPV. Of those, nearly half (44 per cent) were infected with an HPV type that causes cancer. HPV is transmitted through sexual contact and persistent infections by specific types of HPV can cause cancer. Researchers at the International Agency for Research on Cancer estimate that HPV was responsible for 610,000 cases of cancer worldwide in 2008, about 5% of the world’s cancer burden. Most of these are cervical cancer, but HPV is also an important cause of cancers of the head and neck, anus, penis, vulva, and vagina. The World Health Organization (WHO) estimates that more than a half million women are diagnosed with cervical cancer annually and that the majority die from the disease – making it the 2^nd most frequent cancer among women worldwide. It is also estimated that 20-30 per cent of head/neck cancers are associated with HPV, with growing evidence linking these to the practice of oral sex. Since HPV-associated head and neck cancers are more likely to occur in men, protection of both genders through vaccination is important.

The TRAP-HPV study will recruit 500 sexually active couples in Montreal. The treatment will be vaccination with Gardasil (Merck), the HPV vaccine, and the placebo will be vaccination with Havrix (GSK), a vaccine against hepatitis A. Those vaccinated with Havrix will still be susceptible to HPV infection. A couple can be randomized to both receive Gardasil, one receives Gardasil and the other Havrix, or both receive Havrix (the control group). Couples will be followed for one year with clinic visits to collect genital, anal, and oral samples to determine their HPV infection status. They will also provide information about their demographics and sexual behaviors. Those who wish to participate in the study should contact Ms. Allita Rodrigues at traphpv@mcgill.ca for more information.    

The study is funded primarily by the Canadian Institutes of Health Research and has also been supported by Merck, which provided free HPV vaccines and an unconditional grant to McGill.

FINDINGS:

Women who are 65 and older routinely undergo bone-density testing to screen for osteoporosis. But for those between the ages of 50 and 64, it has been unclear who should be screened.

Researchers sought to determine how well the current screening strategy recommended by the U.S. Preventive Services Task Force — the independent expert panel appointed by the federal government to review and recommend various screenings — would perform in identifying candidates in this age range for screening.

Using health data on women ages 50-64 from the Women's Health Initiative study, the researchers found that the current strategy would identify only 34 percent of women who actually had bone-mineral density in the osteoporosis range.

IMPACT:

The U.S. Preventive Services Task Force strategy may not identify the majority of women in the 50-64 age group who would be potential candidates for osteoporosis therapy. As a result, following the strategy may lead to missed opportunities to decrease fracture risk in at-risk women.

ANN ARBOR—In one of the first studies to show a significant association between BPA and cancer development, University of Michigan School of Public Health researchers have found liver tumors in mice exposed to the chemical via their mothers during gestation and nursing.

"We found that 27 percent of the mice exposed to one of three different doses of BPA through their mother's diet developed liver tumors and some precancerous lesions. The higher the dosage, the more likely they were to present with tumors," said Caren Weinhouse, U-M doctoral student in the School of Public Health's Department of Environmental Health Sciences and first author of the paper published online Feb. 3 in Environmental Health Perspectives.

Mice whose mothers received the highest dosage, 50 mg of BPA per kg diet, were seven times more likely to have tumors than those whose mothers were not exposed to BPA.

The researchers said more research is needed to determine the implications for human health.

"This current study showing liver tumors in mice says let's take another look at BPA and cancer in humans," Weinhouse said, adding that next the lab will look for biomarkers in the mice genes that may signal risk for disease before it develops, and then try to see if similar characteristics are found in humans.

Bisphenol A, or BPA, is a chemical most commonly found in plastics, cash register receipts and the lining of food cans. It once was used in hard plastic bottles, including baby bottles, but many companies have removed it as concerns about health effects have been raised in recent years. Studies have estimated that at least 90 percent of Americans have some level of BPA in their bodies.

Previous research has found precancerous lesions associated with BPA exposure but the U-M study is the first statistically significant finding of clinically evident tumors in any organ, said Dana Dolinoy, the John G. Searle Assistant Professor of Environmental Health Sciences and senior/corresponding author of the study. Specifically, the researchers found that adult offspring of exposed mothers had an increase in liver tumors.

Dolinoy said another interesting finding in their research is that tumor development didn't discriminate by sex.

"In general, females are at lower risk of spontaneous development of liver cancer," she said. "That distinction was erased in this study, with both males and females showing tumors."

The researchers fed 6-week-old female mice diets containing one of three environmentally relevant doses of BPA prior to mating, then throughout pregnancy and nursing. They then took one male and one female from each litter and followed them through to 10 months.

Another point of interest in their research, Dolinoy said, is that most other small animal studies have involved direct exposure to BPA. In this research, it was the mothers who were exposed before conception. The offspring, therefore, were exposed as developing fetuses and pups, not as adults.

"A previous study that exposed adult mice to much higher doses of BPA did not show the same link to cancer development," she said. "This tells us the timing of exposure and the dosage are extremely critical in evaluating study outcomes."

One year ago, Dolinoy's lab found BPA in human fetal liver tissue, demonstrating that there is considerable exposure to the chemical during pregnancy. In that study, they also found a proportionately higher concentration of free BPA—as opposed to conjugated forms modified by the body for elimination—showing that the ability to flush the chemical from the body is not the same in fetuses as in adults.

The ADA Foundation is accepting applications until March 14 for its 2014 Allied Dental Student Scholarship Program.

The ADAF plans to award 30 merit-based scholarships of $1,000 to 15 students studying to become dental hygienists, 10 students studying to become dental assistants and five students studying to become dental laboratory technicians.
