CPTF Statement Supporting Maryland House Bill 1098
To Ban State Funds for Artificial Turf and Playgrounds
March 5, 2020

Diana Zuckerman, PhD, President

Thank you for the opportunity to express our strong support for of HB 1098, to restrict the funding of additional artificial turf fields and playground surfaces in Maryland.

As a long-time resident of Montgomery County and president of the National Center for Health Research (NCHR), I am hoping that this bill will finally get the support it deserves.  NCHR is a non-profit public health organization which analyzes and explains scientific and medical information that can be used to improve policies, programs, services, and products.

Our organization has been testifying and writing about the dangers of synthetic turf and playground surfaces for several years, and we’ve testified before state, local and federal legislative bodies and regulatory agencies.  Our scientific staff has reviewed all publicly available scientific studies pertaining to the health impact of the lead and toxic chemicals that are in artificial turf and playground surfaces, compared to natural surfaces such as grass and engineered wood fiber.

In the last year, scientists have reported finding potentially dangerous levels of lead in artificial turf fields and playground surfaces.  In addition, plastic and synthetic rubber are made with different types of hormone-disrupting chemicals, some of which are known to be particularly harmful to growing children.  Scientists at the National Institute of Environmental Health Sciences, which is an institute of NIH, have concluded that these chemicals can be threats to health even at low levels.  According to research at Yale University, 20% of the 96 chemicals they found in samples at five different synthetic turf companies were classified as probable carcinogens.[1]

Manufacturers and advocates for synthetic turf often state that artificial turf has been declared safe by federal authorities.  That is completely untrue.  It is essential to understand that there are no federal requirements for safety testing of these synthetic turf products before they are sold.   Although the EPA and the federal Consumer Product Safety Commission are jointly studying the chemicals used in these products, they have not released any data on studies of children exposed to these fields and playgrounds day after day and week after week.

We commend you for considering how to reverse the dangerous trend of replacing natural fields and playground surfaces with materials that are dangerous to our children’s health, potentially dangerous to adult fertility and health, and bad for our environment.  In the last year, we’ve learned new information about lead and PFAS in artificial turf, as well as the risks of some of the newer infill materials that turf companies are using to replace tire crumb.

Tire crumb, used as infill for artificial turf fields and also used for colorful rubber playground surfaces, has well-known risks, containing lead as well as chemicals that have the potential to increase obesity; contribute to early puberty; cause attention problems such as ADHD; exacerbate asthma; and eventually cause cancer.  However, the plastic grass itself has dangerous levels of lead, PFAS, and other toxic chemicals as well.  PFAS are of particular concern because they are “forever chemicals” that get into the human body and are not metabolized, accumulating over the years. Replacing tire waste with silica, zeolite, and other materials also has substantial risks.

Federal agencies such as the EPA and the U.S. Consumer Product Safety Commission have been investigating the safety of these products.  Despite claims to the contrary, none have demonstrated that artificial turf is safe.  Although the Trump Administration’s EPA stated that there was no conclusive evidence that the levels of chemicals in artificial turf was harmful to children, they made it clear that their research was based on assumptions rather than scientific research on children.

Lead

The American Academy of Pediatrics states that no level of lead exposure is safe for children, because lead can cause cognitive damage even at low levels.  Some children are even more vulnerable than others, and that can be difficult or even impossible to predict.  Since lead has been found in tire crumb as well as new synthetic rubber, it is not surprising that numerous artificial turf fields and playgrounds made with either tire crumb or “virgin” rubber have been found to contain lead.  However, the Centers for Disease Control and Prevention (CDC) also warns that the “plastic grass” made with nylon or some other materials also contain lead.  Whether from infill or from plastic grass, the lead doesn’t just stay on the surface.  With wear, the turf materials turn to dust that is invisible to the eye but that children are breathing in when they play.

Why are chemicals that are banned from children’s toys allowed in artificial turf and rubber playground surfaces?

Synthetic rubber and plastic are made with different types of endocrine (hormone) disrupting chemicals (also called EDCs) and other toxins.  There is very good evidence regarding these chemicals in tire crumb, based on studies done at Yale and by the California Office of Environmental Health Hazard Assessment (OEHHA).

The California OEHHA conducted three laboratory studies to investigate the potential health risks to children from playground surfaces made from tire waste.1 The researchers created a chemical solution that mimicked the conditions of a child’s stomach and placed 10 grams of tire shreds in it for 21 hours at a temperature of 37°C.  One study mimicked a child touching the tire shreds and then touching her mouth by wiping recycled tire playground surfaces and measuring chemical levels on the wipes.  To evaluate skin contact alone, the researchers tested guinea pigs to see if rubber tire playground samples caused any health problems.  Results of the OEHHA studies showed that five chemicals, including four PAHs, were found on wipe samples.  One of the PAHs, “chrysene,” was higher than the risk level established by the OEHHA, and therefore, could possibly increase the chances of a child developing cancer.

A 2018 report by Yale scientists detected 92 chemicals in samples from 6 different artificial turf companies, including unused bags of tire crumb. Unfortunately, the health risks of most of these chemicals had never been studied.  However, 20% of the chemicals that had been tested are classified as probable carcinogens and 40% are irritants that can cause asthma or other breathing problems, or can irritate skin or eyes.[2]

There are numerous studies indicating that endocrine-disrupting chemicals found in rubber and plastic cause serious health problems. Scientists at the National Institute of Environmental Health Sciences (which is part of NIH) have concluded that unlike most other chemicals, hormone-disrupting chemicals can be dangerous at very low levels, and the exposures can also be dangerous when they combine with other exposures in our environment.

That is why the Consumer Product Safety Commission has banned numerous endocrine-disrupting chemicals from toys and products used by children. The products involved, such as pacifiers and teething toys, are banned even though they would result in very short-term exposures compared to artificial turf or playground surfaces.

A report warning about possible harm to people who are exposed to rubber and other hormone disrupting chemicals at work explains that these chemicals “can mimic or block hormones and disrupt the body’s normal function, resulting in the potential for numerous health effects… Similar to hormones, EDC can function at very low doses in a tissue-specific manner and may exert non-traditional dose–response because of the complicated dynamics of hormone receptor occupancy and saturation.”[3]

Studies are beginning to demonstrate the contribution of skin exposure to the development of respiratory sensitization and altered pulmonary function. Not only does skin exposure have the potential to contribute to total body burden of a chemical, but also the skin is a highly biologically active organ capable of chemical metabolism and the initiation of a cascade of immunological events, potentially leading to adverse outcomes in other organ systems.

Scientific Evidence of Cancer and Other Serious Harm

It is essential to distinguish between evidence of harm and evidence of safety. Like the Trump Administration’s EPA, companies that sell and install artificial turf often claim there is “no evidence children are harmed” or “no evidence that the fields cause cancer.” This is often misunderstood as meaning the products are safe or are proven to not cause harm. Neither is true.

It is true that there no clear evidence that an artificial turf field has caused specific children to develop cancer. However, the statement is misleading because it is virtually impossible to prove any chemical exposure causes one specific individual to develop cancer.

As an epidemiologist, I can also tell you that for decades there was no evidence that smoking or Agent Orange caused cancer.  It took many years to develop that evidence, and the same will be true for artificial turf.

I have testified about the risks of these materials at the U.S. Consumer Product Safety Commission, as well as previous Maryland hearings.  I am sorry to say that I have repeatedly seen and heard scientists paid by the turf industry and other turf industry lobbyists say things that are absolutely false.  They claim that these products are proven safe (not true) and that federal agencies have stated there are no health risks (also not true).

However, we know that the materials being used in artificial turf and rubber playground surfaces contain carcinogens, and when children are exposed to those carcinogens day after day, week after week, and year after year, they increase the chances of our children developing cancer, either in the next few years or later as adults.  That should be adequate reason not to install them in your community.  That’s why I have spoken out about the risks of artificial turf in my community and on a national level.  The question must be asked: if they had all the facts, would Maryland families choose to spend millions of taxpayer dollars on fields that are unhealthy and unsafe rather than well-designed natural grass fields?

Dangerously Hot and Hard Fields

Summers in Maryland can get hot.  Even when the temperature is a pleasant 80 degrees Fahrenheit, artificial turf and playground surfaces can reach 150 degrees or higher.  Obviously, turf and playground surfaces are likely to be even hotter than 150 degrees on a sunny 90 degree day.  That can cause “heat poisoning” as well as burns.

Artificial turf fields get hard as well.  Turf companies recommend annual tests at 10 locations on each turf field, using something called a Gmax scores.  A Gmax score over 200 is considered extremely dangerous and is considered by industry to pose a death risk.  However, the synthetic turf industry and ASTM (American Society for Testing and Materials), suggest scores should be even lower — below 165 to ensure safety comparable to a grass field.  Are Maryland communities paying to have these tests conducted on all public artificial turf fields?

The hardness of natural grass fields is substantially influenced by maintenance, rain and other weather; if the field gets hard, aeration water will make it safe again.  In contrast, once an artificial turf field has a Gmax score above 165, it needs to be replaced because while the scores can vary somewhat due to weather, the scores will inevitably get higher because the turf will get harder.  Gmax testing involves testing 10 different areas of a playing fields, to make sure all are considered safe.  Some officials average those 10 scores to determine safety; however, experts explain that is not appropriate.  If a child (or adult) falls, it can be at the hardest part of the field, which is why safety is determined based on each area tested.

Environmental Issues

In addition to the health risks to school children and athletes, approximately three tons of infill materials migrate off of each synthetic turf field into the greater environment each year.  About 2-5 metric tons of infill must be replaced every year for each field, meaning that tons of the infill have migrated off the field into grass, water, and our homes.  The fields also continuously shed microplastics as the plastic blades break down.[4,5] These materials may contain additives such as PAHs, flame retardants, UV inhibitors, etc., which can be toxic to marine and aquatic life; and microplastics are known to migrate into the oceans, food chain, and drinking water and can absorb and concentrate other toxins from the environment.[6,7,8]

Synthetic surfaces also create heat islands.[9,10]  In contrast, organically managed natural grass saves energy by dissipating heat, cooling the air, and reducing energy to cool nearby buildings.  Natural grass and soil protect groundwater quality, biodegrade polluting chemicals and bacteria, reduce surface water runoff, and abate noise and reduce glare.[11]

Envirofill and Alternative Infills

Envirofill artificial turf fields are advertised as “cooler” and “safer,” but our research indicates that these fields are still at least 30-50 degrees hotter than natural grass. Envirofill is composed of materials resembling plastic polymer pellets (similar in appearance to tic tacs) with silica inside. Silica is classified as a hazardous material according to OSHA regulations, and the American Academy of Pediatrics specifically recommends avoiding it on playgrounds. The manufacturers and vendors of these products claim that the silica stays inside the plastic coating.  However, sunlight and the grinding force from playing on the field breaks down the plastic coating. For that reason, even the product warranty admits that only 70% of the silica will remain encapsulated. The other 30% can be very harmful as children are exposed to it in the air.

In addition, the Envirofill pellets have been coated with an antibacterial called triclosan.  Triclosan is registered as a pesticide with the EPA and the FDA has banned triclosan from soaps because manufacturers were not able to prove that it is safe for long-term use.  Research shows a link to liver and inhalation toxicity and hormone disruption.  The manufacturer of Envirofill says that the company no longer uses triclosan, but they provide no scientific evidence that the antibacterial they are now using is any safer than triclosan.  Microscopic particles of this synthetic turf infill will be inhaled by children, and visible and invisible particles come off of the field, ending up in shoes, socks, pockets, and hair.

In response to the concerns of educated parents and government officials, other new materials are now being used instead of tire crumb and other very controversial materials.  However, all the materials being used (such as volcanic ash, corn husks, and Corkonut) have raised concerns and none are proven to be as safe or effective as well-designed grass fields.

Conclusions

There have never been any safety tests required prior to sale that prove that any artificial turf products are safe for children who play on them regularly.  In many cases, the materials used are not publicly disclosed, making independent research difficult to conduct.  None of these products are proven to be as safe as natural grass in well-constructed fields.

I have cited several relevant scientific articles on artificial turf in this letter, and there are numerous studies and growing evidence of the harm caused by these synthetic materials.  I would be happy to provide additional information upon request (dz@center4research.org).

I am not paid to write this statement.  I am one of the many parents and scientists who are very concerned about the impact of artificial fields on our children.  Your decisions about artificial turf and playground materials will directly and indirectly help educate parents throughout the state, making it even more important that your decision is based on scientific evidence, not on sales pitches by individuals with conflicts of interest.

Officials in communities all over the country have been misled by artificial turf salespeople. They were erroneously told that these products are safe.  But on the contrary, there is clear scientific evidence that these materials are harmful.  The only question is how much exposure is likely to be harmful to which children?  We should not be willing to take such a risk.  Our children deserve better.

Please pass HB 1098 and thank you for addressing this critical public health issue.

NCHR’s Testimony to FDA on TOOKAD to Treat Low-Risk Prostate Cancer

Diana Zuckerman, National Center for Health Research, February 26, 2020


Thank you for the opportunity to speak today.  I am Dr. Diana Zuckerman, president of the National Center for Health Research. Our center analyzes scientific and medical data to provide objective health information to patients, health professionals, and policy makers. We do not accept funding from drug or medical device companies, so I have no conflicts of interest.

Although active surveillance is recommended for many patients with low-risk prostate cancer, some patients prefer treatment and that can be a reasonable choice as long as the treatment has a meaningful benefit and does not increase patients’ harms. However, the clinical data for TOOKAD that we are discussing today do not clearly demonstrate that its benefits outweigh its risks – efficacy is uncertain, particularly for U.S. patients, and the drug has the well-known very negative side effects typical of prostate cancer treatments.  

There are 5 major problems with the data, and the FDA did an excellent job of expressing their concerns:

#1.  There was only 1 clinical trial. Replication is the key to science, and effective treatments are available for prostate cancer, so the FDA should not approve a new treatment based on just one study.

#2.  This one trial took place in Europe, and 99.8% of participants were white.  Five patients – not 5% but only 5 men — were not white. Given the higher percentage of African American men who die of prostate cancer, this lack of diversity should not be considered acceptable, unless the FDA is considering approving this product for white men only.

#3. The accuracy of detecting cancer is one major problem. The data showed a high false negative rate. 13.5% of those in the active surveillance arm had a negative biopsy after 2 years. Since it is unlikely that the cancer would spontaneously disappear, this probably reflects false positives in the original diagnosis or false negatives in the post-test. This high false negative rate raises major concerns about the accuracy of biopsies in the treatment arm and at baseline. 

#4. Further, there was a large amount of missing data regarding biopsies at 24 months. Unfortunately, 18.4% of the patients in the treatment arm and 41.5% of those in the active surveillance arm were missing these crucial pieces of information regarding efficacy.  That makes it impossible to draw conclusions based on this one study. 

 #5. The trial was open-label, meaning patients as well as those collecting the data knew whether a particular patient was receiving the treatment or active surveillance. The decision to pursue definitive therapy  — such as surgery — was a subjective decision. Wouldn’t active surveillance patients be more likely to choose treatments later. Also, when biopsy results were uncertain, pathologists may have been biased by their knowledge of whether or not a patient was assigned to the treatment group. 

The FDA held a workshop in September 2018 to discuss issues related to clinical trials of novel treatments for localized prostate cancer.  They concluded that treatment endpoints might be clinically meaningful only if 1) the patients using the new therapy were less likely to undergo subsequent treatment (such as surgery), 2) there was an overall reduction in adverse events, and 3) there was no reduction in long-term cancer control.  However, in this trial, these criteria were not met. 95% of those treated with TOOKAD had adverse event in the weeks after treatment compared to 55% of the men on active surveillance. For many men these problems continued 2 years after treatment, when 34% continued to have urinary problems compared to 16% with active surveillance. Two years after treatment, 38% of patients treated with TOOKAD had erectile dysfunction, compared with 12% of those assigned to active surveillance. In other words, erectile dysfunction was 3x as prevalent among those treated with TOOKAD.

The long-term complications of the treatment that are unclear.  In addition to the urinary problems and ED that might be worse for those who are subsequently treated with surgery, it may be more difficult to obtain accurate biopsies. 

The American Urological Association recommends active surveillance as the best available treatment for low-risk prostate cancer patients, and the data clearly support that recommendation.  We understand that the fear of cancer can persuade men to seek treatment, but if so they should not be bamboozled by ads to choose a product that may have no benefits for them but that does have clear risks of erectile dysfunction and urinary problems. If the FDA thinks this product might have a useful benefit, they should require at least one double-blind study – preferably two – since the treatment does not involved surgery and is therefore easier to blind.  The studies should also include a patient population that represents the diversity of men with prostate cancer. There is no need to rush to approve this particular treatment based on a single, open label trial with endpoints of questionable clinical relevance and problems with inaccurate diagnoses. Better research needs to be completed before approval because the sponsor did not comply with FDA’s recommendations for the study and was even less likely to do so after the product is approved.   

The Oncologic Drugs Advisory Committee voted 13 to 2 against approval of TOOKAD to treat low-risk prostate cancer.

NCHR’s Comments on FDA’s Notice on the Modified Risk Tobacco Product Applications for IQOS System With Marlboro Heatsticks

National Center for Health Research, February 24, 2020


National Center for Health Research’s Public Comments on FDA’s Notice on the Modified Risk Tobacco Product Applications  for IQOS System With Marlboro Heatsticks

Thank you for the opportunity to comment on the FDA Notice on the Modified Risk Tobacco Product Applications for IQOS System With Marlboro Heatsticks, Marlboro Smooth Menthol Heatsticks, and Marlboro Fresh Menthol Heatsticks submitted by Philip Morris International.

The National Center for Health Research (NCHR) is a nonprofit think tank that conducts, analyzes, and scrutinizes research, policies, and programs on a range of issues related to health and safety. We do not accept funding from companies that make products that are the subject of our work.

We strongly oppose the approval of this modified risk application by Philip Morris International. According to the FDA, a modified risk tobacco product needs to demonstrate that it (1) significantly reduces harm to smokers and (2) promotes public health. However, there is insufficient evidence to support the claim that these products significantly reduce harm for smokers. Further, there are potential risks to public health because these products may be appealing to non-smokers, particularly adolescents.The products do contain nicotine, which is addictive.

The applicant claims that “switching completely from cigarettes to the IQOS system can reduce the risks of tobacco-related diseases.” They also claim that it delivers tobacco taste and nicotine satisfaction, which could promote IQOS use as an alternative to smoking cigarettes. However, there is not sufficient data that cigarette smokers would switch to complete IQOS use instead of continuing to smoke traditional cigarettes and thus engage in dual use. The study designs, for example, do not show that consumers’ actual use of the product would significantly reduce the use of traditional cigarettes or result in them switching completely from cigarette use. Without that scientific evidence, there is no proof to support the applicant’s claim that this product leads to a substantial reduction in toxicity.

Nearly 90% of smokers smoked their first cigarette before the age of 18,1 yet adolescents were not included in any of the studies provided by the applicant. The vaping epidemic among adolescents illustrates why we should be concerned about lack of data on teenagers. Research has shown that over half of 12th graders who vape reported that they do so “in order to “see what it’s like,” and one-third report that they vape “because it tastes good.”2 The interest that adolescents show in vaping suggest that adolescents who previously did not consume tobacco products may be interested in trying a novel form of smoking, particularly one with a flavor, such as menthol. Since the applicant has failed to provide any research on the likely impact on adolescents, we can’t assume that adolescents would not be enticed to try the product.

The main reason why we oppose a risk mitigation claim for these products is that they have not been proven to reduce risk. In addition, previous studies have demonstrated that adolescents are likely to perceive products with risk-mitigation claims as less harmful, and Philip Morris International has failed to demonstrate that this would not be the case for their IQOS system. To add to the public health concerns, the effects of the risk mitigation claims in advertising and marketing were not tested, despite the fact that some tobacco advertisements can increase use among youth. The increase in vaping among youth has demonstrated that adolescents are swayed by advertising, and that once they begin a habit such as vaping or smoking, they are unlikely to stop.

In summary, the data provided do not adequately support the claim that the IQOS systems 1) significantly reduce harm for smokers and 2) promote public health. A modified risk statement may encourage people, particularly adolescents, who do not smoke to begin using this tobacco product. At the same time, such a statement could lead to more dual usage among current smokers thinking that this is a safe alternative.

National Center for Health Research Written Statement to Greenwich Board of Education

National Center for Health Research, February 19, 2020


Written Statement to Greenwich Board of Education

Diana Zuckerman, PhD, National Center for Health Research

February 19, 2020

Dear Chairman Bernstein and Members of the Greenwich Board of Education:

I am disappointed that I was unable to be there in person for your meeting on February 20, but I wanted to update you on the latest research about the health risks of artificial turf for children and adults.

As President of the National Center for Health Research, I want to share the information we have provided to Members of Congress, state and federal agencies, state and local legislators, parents, and others who want to ensure that our children are not exposed to dangerous chemicals or metals when they play on artificial turf or playgrounds. Our nonprofit think tank is located in Washington, D.C. Our scientists, physicians, and health experts conduct studies and scrutinize research. Our goal is to explain scientific and medical information that can be used to improve policies, programs, services, and products.

We commend you for considering the possible risks of replacing grass fields with artificial turf. In the last year, we’ve learned new information about lead and PFAS in artificial turf, as well as the risks of some of the newer infill materials that turf companies are using to replace tire crumb. Tire crumb has well-known risks, containing chemicals that have the potential to increase obesity; contribute to early puberty; cause attention problems such as ADHD; exacerbate asthma; and eventually cause cancer. However, the plastic grass itself has dangerous levels of lead, PFAS, and other toxic chemicals as well.  PFAS are of particular concern because they are “forever chemicals” that get into the human body and are not metabolized, accumulating over the years. Replacing tire waste with silica, zeolite, and other materials also has substantial risks.

Federal agencies such as the EPA and the U.S. Consumer Product Safety Commission have been investigating the safety of these products. Despite claims to the contrary, none have concluded that artificial turf is safe. Although the Trump Administration’s EPA stated that there was no conclusive evidence that the levels of chemicals in artificial turf was harmful to children, they made it clear that their research was based on assumptions rather than scientific research on children.

Lead

As you know, the American Academy of Pediatrics states that no level of lead exposure should be considered safe for children, because lead can cause cognitive damage even at low levels. Some children are more vulnerable than others, and that can be difficult or even impossible to predict. Since lead has been found in tire crumb as well as new synthetic rubber, it is not surprising that numerous artificial turf fields and playgrounds made with either tire crumb or “virgin” rubber have been found to contain lead. However, the Centers for Disease Control and Prevention (CDC) also warns that the “plastic grass” made with nylon or some other materials also contain lead. Whether from infill or from plastic grass, the lead doesn’t just stay on the surface. With wear, the turf materials turn to dust that is invisible to the eye but that children are breathing in when they play.

Why are chemicals that are banned from children’s toys allowed in artificial turf and rubber playground surfaces?

Synthetic rubber and plastic are made with different types of endocrine (hormone) disrupting chemicals (also called EDCs). There is very good evidence regarding these chemicals in tire crumb, based on studies done at Yale and by the California Office of Environmental Health Hazard Assessment (OEHHA).[1]

A 2018 report by Yale scientists detected 92 chemicals in samples from 6 different artificial turf companies, including unused bags of tire crumb. Unfortunately, the health risks of most of these chemicals had never been studied. However, 20% of the chemicals that had been tested are classified as probable carcinogens and 40% are irritants that can cause asthma or other breathing problems, or can irritate skin or eyes.[2]

There are numerous studies indicating that endocrine-disrupting chemicals found in rubber and plastic cause serious health problems. Scientists at the National Institute of Environmental Health Sciences (which is part of NIH) have concluded that unlike most other chemicals, hormone-disrupting chemicals can be dangerous at very low levels, and the exposures can also be dangerous when they combine with other exposures in our environment. 

That is why the Consumer Product Safety Commission has banned numerous endocrine-disrupting chemicals from toys and products used by children. The products involved, such as pacifiers and teething toys, are banned even though they would result in very short-term exposures compared to artificial turf or playground surfaces.

A report warning about possible harm to people who are exposed to rubber and other hormone disrupting chemicals at work explains that these chemicals “can mimic or block hormones and disrupt the body’s normal function, resulting in the potential for numerous health effects. Similar to hormones, EDC can function at very low doses in a tissue-specific manner and may exert non-traditional dose–response because of the complicated dynamics of hormone receptor occupancy and saturation.”[3]

Studies are beginning to demonstrate the contribution of skin exposure to the development of respiratory sensitization and altered pulmonary function. Not only does skin exposure have the potential to contribute to total body burden of a chemical, but also the skin is a highly biologically active organ capable of chemical metabolism and the initiation of a cascade of immunological events, potentially leading to adverse outcomes in other organ systems.

Scientific Evidence of Cancer and Other Systemic Harm

It is essential to distinguish between evidence of harm and evidence of safety. Like the Trump Administration’s EPA, companies that sell and install artificial turf often claim there is “no evidence children are harmed” or “no evidence that the fields cause cancer.” This is often misunderstood as meaning the products are safe or are proven to not cause harm. Neither is true.

It is true that there no clear evidence that an artificial turf field has caused specific children to develop cancer. However, the statement is misleading because it is virtually impossible to prove any chemical exposure causes one specific individual to develop cancer.

As an epidemiologist, I can also tell you that for decades there was no evidence that smoking or Agent Orange caused cancer. It took many years to develop that evidence, and the same will be true for artificial turf. 

I have testified about the risks of these materials at the U.S. Consumer Product Safety Commission as well as state legislatures and city councils. I am sorry to say that I have repeatedly seen and heard scientists paid by the turf industry and other turf industry lobbyists say things that are absolutely false. They claim that these products are proven safe (not true) and that federal agencies have stated there are no health risks (also not true). 

However, we know that the materials being used in artificial turf and rubber playground surfaces contain carcinogens, and when children are exposed to those carcinogens day after day, week after week, and year after year, they increase the chances of our children developing cancer, either in the next few years or later as adults. That should be adequate reason not to install them in your community. That’s why I have spoken out about the risks of artificial turf in my community and on a national level. The question must be asked: if they had all the facts, would Greenwich or any other community choose to spend millions of dollars on fields that are less safe than well-designed natural grass fields?

Dangerously Hot and Hard Fields

I lived in Connecticut for several years while on the faculty at Yale and Vassar, and I know the climate well. When the weather is warm and/or sunny, it is usually quite pleasant to be outside – as long as you aren’t on artificial turf or an outdoor rubber surface. Even when the temperature above the grass is 80 degrees Fahrenheit, artificial turf can reach 150 degrees or higher. Obviously, a 90 degree day is likely to be even hotter than 150 degrees on turf. That can cause “heat poisoning” as well as burns.

Artificial turf fields get hard as well. Turf companies recommend annual tests at 10 locations on each turf field, using something called a Gmax scores. A Gmax score over 200 is considered extremely dangerous and is considered by industry to pose a death risk. However, the synthetic turf industry and ASTM (American Society for Testing and Materials), suggest scores should be even lower — below 165 to ensure safety comparable to a grass field. Is Greenwich paying to have these tests conducted on all your public artificial turf fields?

The hardness of natural grass fields is substantially influenced by rain and other weather; if the field gets hard, rain or watering will make it safe again. In contrast, once an artificial turf field has a Gmax score above 165, it needs to be replaced because while the scores can vary somewhat due to weather, the scores will inevitably get higher because the turf will get harder. Gmax testing involves testing 10 different areas of a playing fields, to make sure all are considered safe.  Some officials average those 10 scores to determine safety; however, experts explain that is not appropriate. If a child (or adult) falls, it can be at the hardest part of the field, which is why that is the way safety is determined.

Environmental Issues

In addition to the health risks to school children and athletes, approximately three tons of infill materials migrate off of each synthetic turf field into the greater environment each year. About 2-5 metric tons of infill must be replaced every year for each field, meaning that tons of the infill have migrated off the field into grass, water, and our homes.[4] The fields also continuously shed microplastics as the plastic blades break down.[5,6] These materials may contain additives such as PAHs, flame retardants, UV inhibitors, etc., which can be toxic to marine and aquatic life; and microplastics are known to migrate into the oceans, food chain, and drinking water and can absorb and concentrate other toxins from the environment.[7,8,9]

Synthetic surfaces also create heat islands.10,11 In contrast, organically managed natural grass saves energy by dissipating heat, cooling the air, and reducing energy to cool nearby buildings. Natural grass and soil protect groundwater quality, biodegrade polluting chemicals and bacteria, reduce surface water runoff, and abate noise and reduce glare.[12]

Envirofill and Alternative Infills

Envirofill artificial turf fields are advertised as “cooler” and safer, but our research indicates that these fields are still at least 30-50 degrees hotter than natural grass. Envirofill is composed of materials resembling plastic polymer pellets (similar in appearance to tic tacs) with silica inside. Silica is classified as a hazardous material according to OSHA regulations, and the American Academy of Pediatrics specifically recommends avoiding it on playgrounds. The manufacturers and vendors of these products claim that the silica stays inside the plastic coating. However, sunlight and the grinding force from playing on the field breaks down the plastic coating. For that reason, even the product warranty admits that only 70% of the silica will remain encapsulated. The other 30% can be very harmful as children are exposed to it in the air. 

In addition, the Envirofill pellets have been coated with an antibacterial called triclosan. Triclosan is registered as a pesticide with the EPA and the FDA has banned triclosan from soaps because manufacturers were not able to prove that it is safe for long-term use. Research shows a link to liver and inhalation toxicity and hormone disruption. The manufacturer of Envirofill says that the company no longer uses triclosan, but they provide no scientific evidence that the antibacterial they are now using is any safer than triclosan. Microscopic particles of this synthetic turf infill will be inhaled by children, and visible and invisible particles come off of the field, ending up in shoes, socks, pockets, and hair.

In response to the concerns of educated parents and government officials, other new materials are now being used instead of tire crumb and other very controversial materials. However, all the materials being used (such as volcanic ash, corn husks, and Corkonut) have raised concerns and none are proven to be as safe or effective as well-designed grass fields. 

Conclusions

There have never been any safety tests required prior to sale that prove that any artificial turf products are safe for children who play on them regularly. In many cases, the materials used are not publicly disclosed, making independent research difficult to conduct. None of these products are proven to be as safe as natural grass in well-constructed fields. 

I have cited several relevant scientific articles on artificial turf in this letter, and there are numerous studies and growing evidence of the harm caused by these synthetic materials. I would be happy to provide additional information upon request (dz@center4research.org).

I am not paid to write this statement. I am one of the many parents and scientists who are very concerned about the impact of artificial fields on our children. Last year, I told members of the BET that their decision about artificial turf can save lives and improve the health of children in Greenwich.  You owe it to your community to make sure you know the risks of artificial turf and do all you can to protect Greenwich children from the known risks and also the suspected risks.  Because of Greenwich’s reputation as a well-educated and affluent community, your decisions about artificial turf in Greenwich will be cited by other communities, making it even more important that your decision is based on scientific evidence, not on sales pitches by individuals with conflicts of interest.

Officials in communities all over the country have been misled by artificial turf salespeople. They were erroneously told that these products are safe. But on the contrary, there is clear scientific evidence that these materials are harmful. The only question is how much exposure is likely to be harmful to which children? We should not be willing to take such a risk. Our children deserve better.

Sincerely,

Diana Zuckerman, Ph.D.

President

NCHR Testimony on Low Nicotine Cigarette Claim

Nina Zeldes, National Center for Health Research, February 14, 2020


Thank you for the opportunity to speak here today. My name is Dr. Nina Zeldes and I am here as a senior fellow speaking on behalf of the National Center for Health Research. Our research center analyzes scientific and medical data and provides objective health information to patients, providers and policy makers. We do not accept funding from drug and medical device companies or tobacco companies, so I have no conflicts of interest.

We strongly oppose the approval of this modified risk application by the 22nd Century Group for their low-nicotine combusted filtered cigarette tobacco products. According to the FDA, a modified risk tobacco product needs to demonstrate that it (1) significantly reduces harm to smokers and (2) promotes public health. Unfortunately, evidence is lacking to support the claim that this product significantly reduces harm for smokers. At the same time, it is likely to entice people who have never smoked, especially adolescents, to start smoking.

As the applicant has pointed out, this low nicotine cigarette poses similar risks of tobacco-related disease as conventional cigarettes. Its only advantage is that it contains much less nicotine, and could therefore be less addictive. However, the claims of reduced harm seem to be based entirely on the assumption that people would smoke less often – an assumption that was not adequately supported by the applicant’s data. For example, this product was rated as less satisfying than smokers’ usual brand of cigarettes and less likely to be used again compared to nicotine gum, raising questions about whether smokers would switch completely to this product and ultimately quit smoking.

The FDA briefing document points out that nicotine is often perceived as causing smoking-related health risks. That means that a claim of a product having “95% less nicotine” will be misunderstood as being less likely to cause cancer, when in fact it just means potentially less addictive. Although the applicant provided a voluntary warning that “less nicotine does NOT mean safer”, study participants who were shown this warning still perceived this product as safer than conventional cigarettes. Additionally, the applicant only tested the claims on packaging and not how they would be used in ads and social media. We’ve all learned that the context and imagery in these ads can vastly alter how these claims are interpreted. Tobacco companies have learned how to make very persuasive ads that go beyond the specific claims that they make.

And as we all know, smoking is a habit that is very difficult to break, and addiction to nicotine is only one of the reasons that quitting is so difficult.

Most smokers start smoking as children and adolescents, and yet adolescents were not included in any of the studies provided by the applicant. Previous studies have demonstrated that this group is likely to perceive products with a risk-mitigation claim as less harmful, but that is not proven in this case.

In conclusion, while the claim that this product contains 95% less nicotine may be factually correct, the company’s claims of health benefits are based on the implied assumption that this product would help smokers quit. If that is supposed to be the benefit, their product should have sought to market this product as a cessation aid. Moreover, the packaging does not explain how to achieve this health benefit. Because of such claims, smokers interested in reducing smoking-related health risks might start using this product, instead of quitting or using available FDA-approved cessation products. Meanwhile, non-smokers, particularly adolescents, might start using this product, thinking it is a safe alternative to other tobacco products.

If we’ve learned anything from the vaping epidemic, it is that adolescents are easy to influence, and once they start a habit like smoking or vaping, they are unlikely to stop. We encourage you to let the FDA know that you do not believe that would be an acceptable outcome.

Thank you.

Coalition Letter Urging Support for the Reversing the Youth Tobacco Epidemic Act

February 4, 2020


See PDF: Coalition Letter Urging Support for HR 2339 2.4.20

U.S. House of Representatives
Washington, DC 20515

Dear Representative:

We are writing to express our strong support for H.R. 2339, the Reversing the Youth Tobacco Epidemic Act of 2019. This legislation will address the current youth e-cigarette epidemic that is undermining the progress made in reducing youth tobacco use.

Use of e-cigarettes by youth has escalated rapidly in recent years, placing a new generation at risk of nicotine addiction and tobacco use. Between 2017 and 2019, e-cigarette use more than doubled among high school students (from 11.7% to 27.5%) and tripled among middle school students (from 3.3% to 10.5%). More than 5.3 million middle and high school students used e-cigarettes in 2019, an alarming increase of more than 3 million in two years. Use of other tobacco products, including cigarettes, cigars and hookah, is also a serious problem. Tobacco use remains the leading preventable cause of death in the United States and is responsible for approximately $170 billion in health care costs each year.

The Reversing the Youth Tobacco Epidemic Act provides a much-needed response to this serious public health problem. Its prohibition on flavored tobacco products, including flavored e-cigarettes, flavored cigars, and menthol cigarettes, is needed to stop tobacco companies from targeting and addicting kids with enticing flavors, such as gummy bear and cotton candy. Flavors mask the harsh taste of tobacco and make it easier for kids to start to use a tobacco product and to become addicted.

The bill’s prohibition on flavored e-cigarettes is all the more important because the Administration’s recently released policy on flavored e-cigarettes will leave thousands of flavored e-liquids and devices on the market. Flavors are a key reason for widespread youth use of e-cigarettes. Ninety-seven percent of current youth e-cigarette users have used a flavored e-cigarette in the past month, and seven out of ten said they used e-cigarettes “because they come in flavors I like.”

The bill’s prohibition on menthol cigarettes, flavored cigars, and other flavored tobacco products will also help protect kids and public health. More than half of youth smokers – and seven in ten African American youth smokers – smoke menthol cigarettes. As a result of decades of pervasive tobacco industry marketing, 85 percent of African-American smokers smoke menthol cigarettes, and menthol is a likely contributor to the higher rates of tobacco-caused death and disease experienced by African Americans. A 2013 Food and Drug Administration (FDA) analysis concluded that menthol cigarettes increase youth initiation, increase nicotine addiction, and make it harder for smokers to quit. Cigars are also available in a wide variety of flavors that make them more attractive to kids. More than one million high school students smoke cigars.

In addition to its prohibition on flavored tobacco products, the Reversing the Youth Tobacco Epidemic Act includes a number of other provisions that will help to reduce youth use of e-cigarettes and use of other tobacco products, including prohibiting online sales of most tobacco products, addressing inappropriate marketing and advertising, and ensuring that FDA will promptly implement the graphic health warnings on cigarette packs and advertising that are required under the 2009 Tobacco Control Act.

Youth use of e-cigarettes and other tobacco products is a problem that will not resolve itself. It will require action by Congress. The Reversing the Youth Tobacco Epidemic Act provides the comprehensive response that is needed. We urge you to support this important legislation when it comes to the House floor.

NCHR Comments on FDA’s Notice on the Modified Risk Tobacco Product Application for Copenhagen Snuff Fine Cut

National Center for Health Research, January 21, 2020


National Center for Health Research’s Public Comments on FDA’s Notice on the Modified Risk Tobacco Product Application for Copenhagen® Snuff Fine Cut

Thank you for the opportunity to comment on the FDA Notice on the Modified Risk Tobacco Product Application for Copenhagen Snuff Fine Cut.

The National Center for Health Research (NCHR) is a nonprofit think tank that conducts, analyzes, and scrutinizes research, policies, and programs on a range of issues related to health and safety. We do not accept funding from companies that make products that are the subject of our work.

We strongly oppose the approval of this modified risk application for Copenhagen Snuff Fine Cut with the claim “IF YOU SMOKE, CONSIDER THIS: Switching completely to this product from cigarettes reduces risk of lung cancer” for the following reasons:

  • This safety claim could result in a higher number of dual users, and there is not sufficient evidence to suggest that dual use would reduce the risk of lung cancer. 
  • Even if an individual’s complete switch from combustible tobacco products to this product reduces a user’s risk of lung cancer, we agree with the FDA’s own website, which indicates that the use of smokeless tobacco products increases the risks of other types of cancers, such as oral, esophageal, and pancreatic cancer, as well as other diseases.
  • Because snuff has risks, data are needed to ensure that the marketing of this product as a modified risk product would not increase the number of non-smokers who would start using tobacco products. Increased use is likely, especially among teens and young adults, because, as with vaping, when people hear claims that a product is “safer,” they often misinterpret that to mean the product is “safe.”
  • Research has already shown that individuals who start using smokeless tobacco products, such as this product, are more likely to start using combustible tobacco products.
  • The modified risk statement could be interpreted as suggesting that Copenhagen Snuff Fine Cut can be used as a smoking cessation strategy. However, the sponsor has not provided scientific evidence that using this product helps people stop smoking. 
  • Although smoking and lung cancer deaths have both gone down in Sweden and Norway, the company has not provided evidence that these “favorable public health outcomes” are due to smokeless tobacco products. In addition, there is no evidence that additional reductions would occur in the U.S. market if this modified risk reduction application is approved, because the healthcare system, tobacco reduction campaigns, popular products and cultural influences are different than they are in Sweden and Norway.

In summary, a modified risk statement may encourage people who do not smoke to begin using this tobacco product and could lead to more dual usage, therefore, this product would not reduce the health risks for lung cancer.

For questions or more information, please contact Nina Zeldes, PhD at the National Center for Health Research at nz@center4research.org or at (202) 223-4000.

Comment to the FDA Docket on the FDA’s Draft Guidance to Improve Patient Communication on Breast Implants

A Working Group comprised of two former presidents of the American Society of Plastic Surgeons, the president of a national research center, and four nationally respected patient advocates came together to find common ground regarding the risks of breast implants.   As individuals (Dr. Scot Glasberg, Dr. Alan Matarasso, Dr. Diana Zuckerman, Ms. Karuna Jagger, Ms. Raylene Hollrah, Ms. Jamee Cook, and Ms. Maria Gmitro), we are urging that the FDA require a black box warning and Patient Informed Consent Check List that provides information about the risks of cancer, breast implant illness, and other serious health problems in explicit and easy-to-understand wording that all individuals considering breast implants can understand, regardless of educational level or stress that is inevitable when a person  is considering surgery.

Black Box Warning

The FDA’s draft Black Box warning is too vaguely worded on BIA-ALCL and breast implant illness, and includes jargon that will not be understood by all patients.  For example, it should specify that breast implants can cause ALCL, breast implants are not lifetime devices (instead of FDA’s proposed Black Box wording that they are “not considered lifetime devices), replace technical jargon, and be more explicit about the evidence regarding breast implant illness instead of making it sound like it is not a real risk.

The FDA draft Black Box states that “breast implants have been associated with the development of a cancer of the immune system called breast implant-associated anaplastic large cell lymphoma (BIA-ALCL).”  Association implies correlation rather than causation.  In fact, the evidence is clear that breast implants can cause BIA-ALCL.

The FDA draft says that the rates of BIA-ALCL “are not well defined.”  Although correct, that terminology will not be understood by all patients.  Instead, it should state that the rates “are not known.”

We agree with the FDA draft that it is important to illustrate the seriousness of BIA-ALCL by stating that “Some patients have died from BIA-ALCL.”

The draft Black Box wording regarding symptoms of breast implant illness would be confusing to patients.  It refers to systemic symptoms, which is the correct term, but not one that all patients would understand.  It does not mention breast implant illness, which although not an established medical term, is one that is well understood by patients.  The FDA draft background paper and Black Box warning both state that “some” patients with breast implants “have reported a variety of systemic symptoms,” which implies that the numbers of women with these symptoms is small and that they reported the symptoms but that they haven’t been diagnosed.  That is incorrect.  The wording should be changed to “patients have experienced a variety of symptoms.”  The FDA proposed Black Box statement that “some patients report complete resolution of symptoms” again implies that these improvements are reported but not medically confirmed.

On the contrary, a review of several well-designed studies by De Boer et al. (2017) found that most women with breast implant illness who had their implants removed and not replaced were confirmed by physicians to have complete or substantial improvement in their symptoms and overall health.

In addition, the FDA draft Black Box does not mention the risk of autoimmune/connective tissue diseases.  The Black Box should specify that “several studies suggest that women with silicone gel or saline-filled breast implants have a small but significant increase in their chances of developing certain autoimmune or connective tissue diseases.” That statement is supported by the largest long-term study to date, by Watad et al. (2018), a retrospective analysis of 24,651 women with breast implants (confirmed by medical records) and 98,604 matched women who did not have breast implants. The strongest association with breast implants (OR>1.5, p<0.001) was recorded for Sjögren’s syndrome, systemic sclerosis (scleroderma) and sarcoidosis, based on new medical diagnoses made after the women received breast implants, which were included in medical records during a period of up to 20 years.  In addition, (Coroneos et al. 2019) reported that Allergan’s study of 60% of the almost 50,000 women they enrolled in their study submitted to the FDA, physicians’ diagnoses of their patients two years after their implant surgery found statistically significant increases in fibromyalgia, rheumatoid arthritis, and lupus compared to the general population.  Although the Mentor data reported in that study are very flawed, the Allergan data, which were provided to the FDA, seem solid.

Patient Informed Consent Checklist

The Breast Implant Working Group created a checklist that was provided to the FDA in October.  This checklist has been endorsed by the American Society of Plastic Surgeons, the National Center for Health Research, Breast Cancer Action, Our Bodies Ourselves, National Women’s Health Network, Jacobs Institute for Women’s Health, Breast Implant Victims Advocacy, Just Call Me Ray, and Breast Implant Safety Alliance.  It was also supported by more than 77,000 individuals who signed a petition that the Working Group provided to FDA officials on December 9, 2019

We agree with the FDA that the purpose of a patient checklist is to provide information for patients considering breast implants for augmentation or reconstruction, so that they can carefully weigh the risks and benefits of breast implants and make the decision that is right for them. Based on our experience with patients, we urge the FDA to ensure that the checklist is:

  • Brief and easy-to-understand, formatted with information on specific issues that are presented succinctly;
  • Jargon-free. Keep in mind that the average reading level in the U.S. is 6th
  • Organized to focus on the information that patients are less likely to obtain from other sources. It should not start with lengthy sections that are not especially interesting to patients.

Focus and Organization of the Checklist

The goal of the checklist should be to provide the most essential information that patients might not get from standard informed consent forms. It is therefore essential that the checklist provide information that thousands of implant patients have stated they were not warned about.  For that reason, the checklist should not focus on surgical and cosmetic risks, which are the types of risks that all patients are warned about in standard consent forms.  Instead of the almost full page of mostly surgical risks that are listed at the beginning of the FDA’s draft checklist, such risks should be summarized very briefly in one sentence, with the checklist focused on other risks that patients could otherwise not be aware of.  Similarly, cosmetic and local risks should be listed last in the checklist, since that information is more likely to be provided through other means.

The FDA draft checklist starts with “Considerations for a Candidate for Successful Breast Implantation,” cancer risk and a short section on “systemic illness.”  We suggest shorter, more focused headings and information to make the checklist more engaging and easy to read.

Who shouldn’t get breast implants?

The above heading should replace “Considerations for a Candidate for Successful Breast Implantation,’ since that latter heading implies that the patient characteristics listed are the only ones that would reduce the chances of complications or other problems.  In terms of content, the FDA draft wording on who should not get breast implants contains important information but is much too long and includes information that could be summarized.  The goal of the checklist should be to provide the most essential information that patients might not get from standard informed consent forms.  We recommend a short summary regarding active infections, cancer, or wound healing, and the following wording instead:

I understand that the safety of breast implants was never studied for people who have autoimmune symptoms or diseases, or a family history of those diseases. Breast implants may be more likely to cause serious health problems and symptoms for these people.  In addition, breast implants may not be safe for anyone with a weakened immune system or certain genetic risk factors that have not yet been identified.

Risk of Cancer: BIA-ALCL (Breast Implant Associated Anaplastic Large Cell Lymphoma)

We recommend that the FDA’s draft wording for BIA-ALCL could be improved as follows:

I understand that there is a small risk for me to develop BIA-ALCL, a cancer of the immune system. BIA-ALCL is a type of lymphoma that develops on or around the scar capsule that surrounds the breast implant. I understand that the symptoms of BIA-ALCL include breast swelling, lumps, pain, and asymmetry that develop after surgical incisions are completely healed, usually years after implant surgery.

Treatment for BIA-ALCL includes removal of the implant and scar capsule, and, if not treated early, may include chemotherapy and radiation. This diagnosis and treatment may be at my own expense and is not always covered by insurance. 

Systemic Symptoms:  Breast Implant Illness

As noted earlier, “Breast Implant Illness” should be the term used, since “systemic symptoms” is not a term that all patients would understand.  Also as noted earlier, the FDA draft guidance and draft checklist consistently imply that the number of women reporting symptoms of breast implant illness is small and that there is no research evidence that the symptoms are caused by their implants.  For example, the FDA’s draft wording that “some women report” implies that a small number of women are claiming an illness that isn’t real.  It is more accurate and meaningful to patients to say that several studies support the apparent causal link to breast implant illness symptoms (Watad et al 2017 and Colaris et al. 2017) and to symptom improvement after implants are removed (DeBoer et al. 2017), for example).  It should also state that the largest, long-term studies also indicate a statistically significant increase in certain autoimmune or connective tissue diseases, as summarized on page 2 of this document, citing Watad et al. 2018 and Coroneos et al. 2019). For that reason, ASPS, researchers, women’s health organizations, and patient groups endorse the following wording:

I understand that because of the lack of long-term safety data, we are still learning about the health problems that result from breast implants.  To date, thousands of women have reported to the FDA or to researchers that they have experienced serious health problems that several studies have linked to their breast implants. This may occur either immediately after getting implants or years later. These often include symptoms such as: joint and muscle pain or weakness, memory and concentration problems, chronic pain, depression, fatigue, chronic flu-like symptoms, migraines, or rashes and skin problems.

Several studies of women with breast implants have shown that they are significantly more likely to be diagnosed with one or more of the following diseases compared to other women:  Chronic Fatigue Syndrome; Multiple Sclerosis (MS); Rheumatoid Arthritis (RA); Sjögren’s syndrome; and Systemic Sclerosis/Scleroderma.

Although women who develop these symptoms or diseases can’t be certain that they were caused by breast implants, several studies indicate that most symptoms improve partially or completely after having their implants and capsules removed.

Breast-Implant Specific Risks

This heading in the FDA’s draft Checklist is misleading, since BIA-ALCL and many other risks of breast implants are specific to breast implants.  More important, this section is much too long and includes too many topic areas.

We therefore recommend the following shorter, more specific sections:

How long do breast implants last?

It’s essential that patients understand what it means when experts say that breast implants “don’t last a lifetime.”  Since many implant patients are young, some think that means they only last 30-50 years.  Even saying “the longer you have them, the more likely they are to break” can be misinterpreted to refer to 30 or 40 years later.  For that reason, the Working Group Checklist specifies “Implants may rupture or leak at any time, and that is more likely the longer you have them” and that “it is likely that I will need other surgeries related to my breast implants over the course of my life.”

The wording should be succinct, explicit, and easy to understand.  Augmentation patients are already aware that their insurance policy does not cover cosmetic surgery, but it is important for them to also know that insurance is unlikely to cover subsequent surgeries due to complications or breakage, since they might mistakenly assume that problems related to implants will be covered even if the initial cosmetic surgery is not.  We recommend the following wording:

I understand that breast implants are not expected to last for the rest of my life.  Implants may rupture or leak at any time, and that is more likely the longer you have them.  In addition, it is likely that I will need other surgeries related to my breast implants over the course of my life.  If I am a cosmetic surgery patient, my health insurance policy may refuse to cover these surgeries for removal, and probably would not cover replacement. These additional surgeries and procedures can include implant removal with or without replacement, muscle and tissue repair, scar revisions, MRI diagnostic exams, or other procedures. I understand that undergoing multiple surgeries may increase my chances of permanent breast deformity.

Chemicals and Metals in Breast Implants

Patients should be informed about the chemicals and metals in the specific make and model of breast implants they are considering.  Since the checklist is for all breast implant patients, it should include a brief, general statement about chemicals and heavy metals, but each patient should get separate, more detailed information about the specific model of implant they are considering.  We recommend the following wording for the checklist:

I understand that all breast implants contain chemicals and small amounts of heavy metals that may cause health problems. I understand that most of these chemicals are confined to the shell of the implant or stay inside the shell.  However, small quantities have been found to diffuse (bleed) from or through the implant shell, even if the implant is intact and not ruptured.

Rupture and Leakage

Patients would benefit from a section with a heading of “Rupture and Leakage.”  Although this overlaps with the issue of how long implants last, more specific information about silent rupture is important.  We recommend the following wording for the checklist, understanding that if FDA no longer recommends MRIs after 3 years, that wording should be revised, but the explicit information about the risks of silicone migration should be included:

I understand that the longer my breast implants are in place, the more likely they are to rupture, especially after the first few years. When a saline implant ruptures, it usually deflates quickly. When a silicone gel implant ruptures, I may not notice any changes and the rupture may not be detected by my doctor or by mammogram, MRI, or sonogram. I understand that an MRI is recommended for silicone gel breast implants 3 years following surgery and every 2 years after that to check for silent rupture, and that these MRIs often are not covered by health insurance. I understand that silicone may migrate from the implant into nearby tissues such as the chest wall, lymph nodes, upper abdominal wall, and into organs such as the liver or lungs where it cannot be removed. Since migrated silicone can cause health problems, it is currently recommended that any ruptured silicone implant should be removed as soon as possible. I understand that, if needed, treatment of these conditions may be at my own expense and not covered by insurance or a manufacturer warranty.

Capsular Contracture

Capsular Contracture is a common complication that therefore should have its own heading.  Our recommended wording is as follows:

I understand that one of the most common complications of breast implants is when the scar tissue capsule that forms around the implant hardens. In some cases, this can be quite painful, distort the shape of the breast, and can make mammography more painful and less accurate. Removing the implant and capsule without replacing the implant is the only recommended way to guarantee that this problem is corrected.

Breast Cancer

Breast cancer issues should be a separate heading in the checklist, not part of the section on ACLC, in order to avoid confusion.  Our recommended wording is as follows:

I understand that all breast implants can interfere with mammography and breast exams, possibly delaying the diagnosis of breast cancer. I understand that if I get breast implants, I should inform the mammography technologist about the implants and ask for additional views to improve the accuracy. I understand that mammography can also cause the breast implant to rupture or leak.

Interference with Breastfeeding

Since the data are lacking, our recommended wording is as follows:

I understand that breast implants and breast surgery may interfere with my ability to successfully breastfeed.  No long-term research has been conducted to determine the possible transmission of chemicals and heavy metals in the breast milk of women with implants.

Loss of Sensation to Breast or Nipple(s)

Many women do not understand that breast implant surgery can cause loss of sensation.  While more likely among reconstruction patients, it is important to note that augmentation patients can also experience loss of sensation or painful sensitivity.  We therefore recommend this wording:

I understand that breast implants and breast surgery may cause the nipple or breast to be painful, or to have decreased sensation. These changes may be temporary or permanent, and may affect sexual response or the ability to nurse a baby.

Cosmetic Complications

Cosmetic complications should be the last section of the checklist, because like surgical complications they are often included in standard informed consent documents.  We recommend the following brief, easy to understand, but explicit warnings, such as using the term “sag” instead of ptosis:

I understand that if my breasts had slightly different shapes before surgery, they may remain slightly different after surgery. I understand that the implants may cause the breasts to look slightly different in size or shape. I understand that the implant may move from the original placement location and that may result in asymmetry or other cosmetic problems. Breast implants can cause the breasts to sag over time due to the weight of the implants. I understand that if I am not happy with the results, I may need future surgeries to improve the appearance of my breasts.

NCHR’s Comments on the Safer Technologies Program (STeP) for Medical Devices

National Center for Health Research, November 18, 2019


National Center for Health Research’s Public Comments on 
Safer Technologies Program for Medical Devices; Draft Guidance for
Industry and Food and Drug Administration Staff; Availability
[FDA-2019-D-4048]

Thank you for the opportunity to express our views on the proposed Safer Technologies Program (STeP) for medical devices.

The National Center for Health Research (NCHR) is a non-profit think tank that conducts, analyzes, and scrutinizes research, policies, and programs on a range of issues related to health and safety. We do not accept funding from companies that make products that are the subject of our work, so we have no conflicts of interest.

We appreciate FDA’s efforts to get medical devices with an improved safety profile to consumers and patients more quickly. However, the mission of the FDA is to protect patients and consumers from medical products that are not proven safe or not proven effective. FDA guidance must be very clear how this program would protect patients from unsafe or ineffective medical devices. The proposed guidance is so vaguely worded that it is not possible to have confidence that patients’ needs will be protected.

We agree that increased interactions with FDA throughout the development process and more timely interactions could 1) speed development and review, and 2) improve the quality of the data available for review by providing more consideration into needed data, study design, and early detection of concerns. Unfortunately, most medical devices are cleared through review pathways that require little or no clinical data to demonstrate safety or effectiveness, and while premarket approval applications (PMA) require clinical trial data, those studies are often small, poorly designed, and lacking in appropriate control groups. Thus, while the proposed Safer Technologies Program may get medical devices to patients sooner, the program will be harmful to patients unless it also strengthens the premarket requirements for scientific evidence of safety and effectiveness.

Textured breast implants, Essure, POP mesh, and metal-on-metal hip replacements are just a few of the many examples of devices that were implanted in tens of thousands of patients and consumers prior to being removed from the market due to serious, unexpected complications. It is disturbing that the proposed guidance includes no explicit instructions aimed at reducing the harm caused when patients unwittingly serve as guinea pigs for implants and other devices that were not adequately tested prior to going on the market. It is not fair to patients or their physicians to rely primarily on post-market studies and surveillance, because too many patients will be harmed before those studies are completed, and too many of those studies will never be completed. We therefore respectfully urge the FDA to revise the proposed guidance in ways that ensure that all medical devices undergo more rigorous testing prior to being approved or cleared.

NCHR Testimony on Research Needed on Immunological Responses to Metal in Implants

Diana Zuckerman, PhD, National Center for Health Research, November 13, 2019


Thank you for the opportunity to speak at this Advisory Committee meeting today regarding immunological responses to metal in implants.

The National Center for Health Research is a nonprofit research center that focuses on the quality of medical products and procedures and does not accept funding from medical device companies or pharmaceutical companies. I’m here today to share my perspective as a scientist as well as a patient.  I am trained in epidemiology and served on the faculty at Vassar and Yale and as a researcher at Harvard.  I’ve also worked in the U.S.  Congress on FDA issues and as president of the National Center for Health Research I have  a great deal of experience with FDA regulatory issues.

In addition, I got a hip implant 10 years ago, and I’m glad to say my experience has been a very good one.  But at the time I was deciding on the surgery, neither the surgeons I interviewed nor the research literature provided the kind of information I needed to make an informed choice.  In fact, one surgeon recommended a metal-on-metal hip for me because I was relatively young and active.  Fortunately, I was already aware of metal debris issues so I did not make that choice.  But the lack of information then and now was very clear to me as a patient.  I was not able to obtain scientific data from the surgeons or online, including PubMed.

I want to say that this has been one of the most interesting and informative FDA meetings I’ve attended, and the speakers have provided a great deal of important information.

What Research is Needed?

I’m here to talk about the big picture.  We’ve heard this morning about a great deal of research findings and the need for more and better research.  I want to emphasize that we need much better pre-market studies, not just post-market studies.  Pre-market clinical trials are often lacking because of the 510(k) process, but even when premarket clinical trials are conducted, they are often inadequate to provide the information patients deserve.

We need clinical trials and other well-designed studies of large number of patients, and as one of the speakers said this morning, we need to compare information about patients who have good experiences with their implants with those who do poorly with their implants.  These studies need to include a patient population with sufficient diversity in terms of age, sex, race, BMI, activity levels, allergies, and metal sensitivity, to determine how safe and effective the products are for these subgroups.

We need clinical trials and big data analyses that follow patients for years in order to evaluate the effects of wear and changes in immune responses over time.

We heard this morning that patch testing is inadequate to identify which patients will have a negative reaction to an implant, and that other diagnostic testing also has limitations.

I also want to express our concern with the tendency to extrapolate results from an implant used in one part of the body to implants made of the same materials that are intended to be used in another part of the body.   We know from listening to patients that this can result in terrible problems.

We are also concerned about extrapolating results from an earlier version of an implant to a newer implant, when the newer implant differs in ways that could affect safety and effectiveness.  Those differences might be different metals, changes in size or shape, differences in manufacturing, or numerous other changes typically made in an effort to improve implanted devices.

We encourage the FDA to require that studies specifically look for adverse events that are related to immune reaction or wear.  These adverse events might be local or might be systemic, and some of these events would not necessarily be included in studies asking about all adverse events.

Perhaps most important, we need comparative effectiveness studies that compare clinical effectiveness and patient-centered outcomes.  I know that the FDA rarely requires comparative effectiveness studies, but those are the types of studies that are most likely to provide useful information for patients and their physicians.

If certain implants seem to be causing certain reactions with certain kinds of patients, wouldn’t it be very important to know how that compares to other alternatives of the same kind of implants? We can’t treat all hip implants that are polyethylene and metal as if they’re all the same.  We can’t treat all metal-on-metal implants as if they’re the same. We need to compare different models, different implants made in different ways with different materials by different companies and get the kind of real data that patients and physicians can use to make informed decisions. Until then, it won’t be possible to figure out to what extent negative responses and implant failures are due to patient vulnerabilities or sensitivities and how much is due to the difference between various devices.
