WASHINGTON (May 2, 2017) - Some scientific reports have a profound impact on government policy. Sometimes, however, there are significant shortcomings in the research - yet the policy impact continues. Critically analyzing scientific research that underlies regulatory decision making and generating new information to ensure decisions are based on sound science are crucial. A recent analysis by Checkoway et al. has been awarded the Kammer Merit in Authorship Award for its review of the data from a critical epidemiological study used by scientific agencies to assess health risk from formaldehyde exposure. The findings from Checkoway et al call into question the original study's conclusions; the analysis further demonstrates the importance of data availability, research reproducibility and adherence to study design when drawing scientific conclusions. The Kammer Merit in Authorship Award recognizes an outstanding scientific contribution published in the American College of Occupational and Environmental Medicine (ACOEM's) Journal of Occupational and Environmental Medicine (JOEM) during a given year. The winning paper, titled Formaldehyde Exposure and Mortality Risks from Acute Myeloid Leukemia and Other Lymphohematopoietic Malignancies in the US National Cancer Institute Cohort Study of Workers in Formaldehyde Industries, concluded that there is no epidemiological evidence from the National Cancer Institute (NCI) cohort supporting an association between formaldehyde exposure and acute myeloid leukemia (AML). The award was announced late last week. "The findings from this analysis do not support a finding that formaldehyde exposure is a cause of leukemia," said Harvey Checkoway, Ph.D., lead author of the reanalysis and Professor of Family Medicine & Public Health at the University of California, San Diego. "This reanalysis identifies how critical data interpretation is, given that the risk assessments that rely on these analyses ultimately set occupational and environmental exposure standards." Checkoway and his colleagues performed analyses of raw data in an attempt to replicate findings reported from a NCI cohort mortality study of workers from 10 US plants producing or using formaldehyde. The NCI study has been influential in the classification of formaldehyde as a human leukemogen by the International Agency for Research on Cancer (IARC) and the National Institute of Environmental Health Sciences (NIEHS) National Toxicology Program (NTP). In the original analysis NCI investigators defined "peak" exposure to formaldehyde on a relative basis with respect to individual workers' exposures histories. This complicates data interpretations. Using this definition, analyses of updated mortality data for the NCI cohort reported tentative associations of "peak" exposures with myeloid leukemia (ML) and Hodgkin lymphoma (HL) that are inconsistent with other studies. The new research found no association between acute myeloid leukemia (AML) and cumulative, average or frequency of "peak" exposures. This became clear in the new analysis where AML and chronic myeloid leukemia (CML) were evaluated separately, as two types of leukemia are different diseases and have different risk factors. The award-winning Checkoway et al. study conducted more comprehensive analyses of associations of specific lymphohematopoietic malignancies (LHM), especially AML, with peak exposure, using a standard definition of peak exposure. Peak was defined in terms of absolute exposure dose and duration, which permitted direct comparisons among similar studies, strengthening the analysis. Checkoway et al. concluded that no clear associations for peak or cumulative formaldehyde exposures were observed in this cohort for any of the specific LHM, including AML The result of this analysis adds to the weight of evidence that formaldehyde exposure in the workplace does not cause AML, the LHM of greatest concern. It also underscores the need to ensure new information is effectively considered and incorporated into chemical assessments by IARC, NTP and other agencies. "Having this work recognized by ACOEM as a significant contribution in occupational medicine shows how important these findings are to understanding and interpreting the formaldehyde science," said Kimberly White, Ph.D., Senior Director of the American Chemistry Council Formaldehyde Panel.

Environmental health researchers in Bordeaux, France say their new evaluation on the timing of asbestos exposure and mesothelioma risk finds that the younger a person is at first exposure, the more likely they are to develop malignant mesothelioma. Surviving Mesothelioma has more on the website. Click here to read the full article. University of Bordeaux scientists used a job exposure matrix to determine that exposure in younger workers is even more dangerous when it comes to pleural mesothelioma development. that later exposure. “Due to much stronger weights of early doses of asbestos exposure, subjects who accumulated 20 fibres/mL over the entire job history with high doses during the first years and low doses thereafter were at higher risk of pleural mesothelioma than those who accumulated most of the doses later,” writes lead study author Aude Lacourt. The report in the journal Occupational and Environmental Medicine is based on an evaluation of the cases of 1,196 male asbestos workers and 2,369 men of the same age who had never been exposed. “We have all heard cases of people who developed mesothelioma decades later after being exposed just briefly as a teenager,” says Alex Strauss, Managing Editor for Surviving Mesothelioma. “Then there are cases of long-time asbestos workers who never develop mesothelioma. These report is a reminder of the potential importance of timing, which is often overlooked.” To read more about the French study and the potential impact of asbestos exposure timing on mesothelioma development, see Mesothelioma Risk and the Timing of Asbestos Exposure, now available on the Surviving Mesothelioma website.

Exposure to high levels of traffic-related air pollution is seemingly a direct cause of the type of DNA damage that is known as telomere shortening, according to new research from the University of California, Berkeley. Notably, young people with asthma also show evidence of telomere shortening, according to the researchers, meaning that: “Our results suggest that telomere length may have potential for use as a biomarker of DNA damage due to environmental exposures and/or chronic inflammation.” The research was focused around 14 children and adolescents residing in the second-most-polluted city in the US — that is to say, in Fresno, California. The press release provides details: “The researchers assessed the relationship between polycyclic aromatic hydrocarbons (PAHs), a ‘ubiquitous’ air pollutant caused by motor vehicle exhaust; and shortening of telomeres, a type of DNA damage typically associated with aging. “As the exposure to PAHs increased, telomere length decreased in linear fashion. Children and teens with asthma were exposed to higher PAH levels than those without asthma. The relationship between PAH level and telomere shortening remained significant after adjustment for asthma and other factors (age, sex, and race/ethnicity) related to telomere length. “The study adds to previous evidence that air pollution causes oxidative stress, which can damage lipids, proteins, and DNA. Research has suggested that children may have different telomere shortening regulation than adults, which might make them more vulnerable to the damaging effects of air pollution.” John R Balmes, MD, of UC–Berkeley, and other report authors summarized: “Greater knowledge of the impact of air pollution at the molecular level is necessary to design effective interventions and policies.” Well, perhaps. But at this point it’s not actually news to anyone who doesn’t have their hands over their ears that the world’s growing air pollution problems are having a very negative effect on human health. So, it’s more a matter of political will at this point than of evidence. The new findings are detailed in a paper published in the Journal of Occupational and Environmental Medicine.

Children and teens exposed to high levels of traffic-related air pollution have evidence of a specific type of DNA damage called telomere shortening, reports a study in the May Journal of Occupational and Environmental Medicine. Young people with asthma also have evidence of telomere shortening, according to the preliminary research by John R. Balmes, MD, of University of California, Berkeley, and colleagues. They write, "Our results suggest that telomere length may have potential for use as a biomarker of DNA damage due to environmental exposures and/or chronic inflammation." The study included 14 children and adolescents living in Fresno, Calif. -- the second-most polluted city in the United States. The researchers assessed the relationship between polycyclic aromatic hydrocarbons (PAHs), a "ubiquitous" air pollutant caused by motor vehicle exhaust; and shortening of telomeres, a type of DNA damage typically associated with aging. As the exposure to PAHs increased, telomere length decreased in linear fashion. Children and teens with asthma were exposed to higher PAH levels than those without asthma. The relationship between PAH level and telomere shortening remained significant after adjustment for asthma and other factors (age, sex, and race/ethnicity) related to telomere length. The study adds to previous evidence that air pollution causes oxidative stress, which can damage lipids, proteins, and DNA. Research has suggested that children may have different telomere shortening regulation than adults, which might make them more vulnerable to the damaging effects of air pollution. "Greater knowledge of the impact of air pollution at the molecular level is necessary to design effective interventions and policies," Dr. Balmes and coauthors conclude. With further research, telomeres could provide a new biomarker to reflect the cellular-level effects of exposure to air pollution. Telomeres might also provide new insights into the understanding how pollution exposure leads to adverse health outcomes.

Other means besides a registry should be developed to evaluate potential health effects of military burn pits' toxic emissions on exposed service members; data from burn pit registry could be used for other purposes WASHINGTON - Inherent features of registries that rely on voluntary participation and self-reported information make them fundamentally unsuitable for determining whether emissions from military burn pits in Iraq, Afghanistan, and other locations in Southwest Asia caused health problems in service members who were exposed to them, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine. While the U.S. Department of Veterans Affairs' Airborne Hazards and Open Burn Pit (AH&OBP) Registry provides a forum for collecting and recording information on those who choose to participate, a more rigorous and appropriate approach is needed to examine the relationship between the exposures and health outcomes, such as a well-designed epidemiologic study. A previous report by the former Institute of Medicine [now part of the National Academies] found inconclusive evidence on the health effects of exposure to military burn pits and contained advice and recommendations on how a study might be conducted. For some time, the disposal of trash on military bases through open-air burn pits exposed service personnel deployed in Iraq, Afghanistan, and other locations in Southwest Asia to airborne particulate matter and other potential health hazards, which in turn raised concerns about acute and chronic health consequences in these individuals. In 2013, Congress gave the VA one year to create a registry that would acquire exposure and health information on service members and veterans who may have been exposed to airborne hazards during deployment -- such as smoke from burn pits, oil-well fires, dust storms, or pollution. The VA developed an ambitious program to enroll volunteer participants and created the AH&OBP Registry. In response to a congressional mandate, the VA asked the National Academies to analyze the initial months of data collected by the registry and offer recommendations on ways to improve the instrument and the information it collects. Registries are structured systems for collecting and maintaining data on a group of people characterized by a specific disease, condition, exposure, or event as a means to facilitate research, monitor health, or provide information to registrants. Registries that rely on voluntary involvement and self-reported information on exposures and health outcomes are not suitable for assessing the health effects of exposure due to respondents' selective participation, inaccurate recall, or inadvertent or intentional under- or overestimation. Thus, they are an intrinsically poor source of information on exposures, health outcomes, and possible associations among these events, said the committee that carried out the study and wrote the report. Even under the best of circumstances, there are substantial limits to the accuracy of the data they collect and -- when the respondents make up only a small, unrepresentative fraction of the eligible population -- to the generalizability of analyses made with them. The committee stressed that even a well-designed and executed registry would have little value as a scientific tool for health-effects research and would not be an effective substitute for an epidemiologic study. The committee concluded that given the inherent weaknesses, the best use of the AH&OBP Registry is as a means for the eligible population to document their concerns of health problems that may have resulted from their service, bring those concerns to the attention of VA and their health care providers, and supply VA with a roster of people who are interested in burn pit exposure issues. The gathered data could also potentially be used to stimulate and inform new research, such as a well-designed epidemiologic study. The committee recommended that VA's messaging be explicit about the capabilities and limitations of the registry to ensure that participants and others do not form unrealistic expectations. The registry questionnaire collects a number of pieces of information -- including self-reported signs, symptoms, and diseases -- that can alert providers to concerns and problems that may be forgotten or missed during clinical encounters, without regard to whether the information might be relevant to wartime exposures. For example, someone who reported difficulty walking long distances or climbing stairs might be experiencing joint pain, respiratory problems, vascular disease with congestive heart fail¬ure, obesity, or even anxiety. The committee recommended that the VA develop a concise version of a participant's responses that can be downloaded and discussed with a health care provider. If the VA chooses to use the registry for the purposes for which is it most suitable, the committee recommended several changes to the questionnaire to improve and streamline participation. Beyond the inherent weaknesses of voluntary, self-report registries, the committee identified correctable features in the registry's structure and operation as well as in the questions that are asked and the way they are asked. For example, the questionnaire fails to ask questions that could yield improved information related to relevant exposures, such as non-burn pit trash burning, and requires respondents to complete a sometimes lengthy set of repetitive questions regarding deployments before addressing core issues like health. The cumulative effect of these flaws is evidenced by the high percentage of respondents who initiated but did not complete the instrument and the number of questions that had high non-response rates. The VA should eliminate the questionnaire sections that collect information that cannot be productively used in studies appropriate for the registry's data. A 2015 VA report indicated that nearly 40 percent of those who began filling out an AH&OBP Registry questionnaire did not complete it. This is an outcome that should be examined more fully, the committee said. It recommended that the VA evaluate whether and how registrants who did not complete the questionnaire differ from those who did; analyze the determinants of non-completion; and use this information to formulate strategies that encourage registrants to finish and submit their responses as well as improve the completion rate for future participants. An examination of the questionnaire data made available to the committee showed that registry participants who reported more exposures of all types also tended to report more health problems of all types. However, the committee's analyses suggested that such results may be a consequence of the population's selection and the limitations of the self-reported exposure and disease data and do not provide useful information for assessing the health effects of exposure. The committee emphasized that it reached this determination based on the nature of the registry and the data it collects and would have drawn the same conclusion if no or weak associations between the exposures and health outcomes had been found. More generally, the AH&OBP Registry's data collection, administration, and management efforts could be improved by developing a plan to more fully integrate relevant VA and U.S. Department of Defense data sources with the registry's data, as well as offering alternative means of completing the questionnaire, such as a mail-in form or via a computer-assisted phone interview, to ensure that the subset of eligible persons who do not use or have difficulty using the Internet have the opportunity to participate in the registry.

Jobs that involve carrying heavy loads — with effects seen stronger among overweight, obese, and older women — and working night or rotating shifts could reduce a woman’s fertility, a new study has warned. A team from Harvard T.H. Chan School of Public Health made a link between reproductive capacity and these occupational factors, but the underlying cause remains unknown. Yet women who are in a reproductive age and are actively trying to conceive should consider these findings, according to the researchers. The team studied almost 500 women who sought infertility treatment at Massachusetts General Hospital from 2004 to 2015, and compared their jobs’ physical demand and schedules against four specific biomarkers, or genes in the body, associated with fecundity or the ability to reproduce. These biomarkers are the number of immature eggs in the body and mature eggs that can develop into healthy embryos, as well as levels of follicle-stimulating hormone (FSH) and estrogen. The results: the heavier the lifting or moving of heavy objects at work, the lower the amount of antral follicles and eggs. Those who reported lifting heavy objects had 8.8 percent fewer eggs and 14.1 percent fewer mature eggs versus those who never lifted or moved heavy stuff around. This was discovered more pronounced among subjects who were overweight, obese, and ages 37 and above. Working at night or on rotating shifts, too, also appeared inversely related to the number of eggs. The team speculated it may be related to the disruption of one’s body clock or circadian rhythm. "Our study is the first to show that occupational heavy lifting and non-day shifts may be adversely affecting egg production and quality, rather than accelerating ovarian aging,” explained senior author Audrey Gaskins in a statement, also pointing to a disrupted stress-response system brought about by factors like obesity. Reproductive endocrinologist Channa Jayasena, who was not part of the study, said that the study was interesting but there should be a bigger sample size than the less than 500 used in the research. “You need a study in the thousands,” he told CNN, also citing the need to consider differences including socioeconomic status and testosterone levels in the women. Jayasena, however, agreed with the researchers that circadian rhythm may be at play in the differences found in shift work, with each body part — including the ovaries — having its own circadian rhythm. Previous research has reflected the potential ills of shift work, including a greater risk of obesity and heart disease. The findings were discussed Feb. 7 in the journal Occupational and Environmental Medicine. A separate study from the National Institutes of Health (NIH) pinpointed obesity as a factor influencing a couple’s ability to conceive. It showed that if both the partners are obese, then the couple may take almost 55 percent to 59 percent more time to conceive compared to non-obese couples. In most cases, obesity is tied to less successful fertility treatments. Thus experts are urged to make couples conscious of body compositions and weight issues that affect pregnancy during counseling sessions. © 2017 Tech Times, All rights reserved.

The Western Occupational & Environmental Medical Association (WOEMA) has concluded one of its strongest legislative advocacy sessions in California in recent years, helping enact five bills in the state benefiting the practice of occupational and environmental medicine (OEM) there. WOEMA, which represents physicians who practice in California, Arizona, Utah, Nevada, and Hawaii, took strong positions on ten bills affecting OEM during the California Legislature’s 2016 session. Of the six bills it supported actively, five were enacted into law. Of the four bills it actively opposed, none were enacted. Among the bills enacted, which WOEMA had actively supported, were measures to streamline Utilization Review in workers’ compensation cases (Senate Bill 1160), a measure to create a Cal/OSHA standard for indoor heat exposure (Assembly Bill 1045), and a bill creating a “Physician Wellness” program for the state—aimed at providing help for physicians struggling with substance abuse (Senate Bill 1177). Among the bills WOEMA successfully opposed were measures that would have thwarted expert medical judgment in apportionment matters and weakened evidence-based approaches to the care of low back pain. “WOEMA can be happy about its successful legislative track record this year,” said WOEMA President Robert C. Blink MD, MPH, FACOEM. “Our Legislative Committee worked hard to deliver results that are good for patients and help ensure safer, healthier workplaces.” Toward the end of the legislative session WOEMA released a white paper entitled: “Quality Assurance and Quality Improvement in the California Workers’ Compensation System: A Focus on Utilization Review and Beyond.” The paper focuses squarely on finding ways to prevent delays in treatment by improving the process for providers requesting treatment and agents conducting utilization review. WOEMA lobbyist Don Schinske said it’s possible some of the paper’s suggestions could be incorporated during the rule-making process for Senate Bill 1160, which pertains to utilization review and lien filing. "For example, Senate Bill 1160 requires accreditation for utilization review processes by July 1, 2018 and we think there is ample room within the workers’ compensation system to start adding quality metrics which is where WOEMA is focusing its efforts in the year ahead,” Schinske said. About WOEMA: The mission of the Western Occupational and Environmental Medical Association (WOEMA is to promote and protect the health of people at work and in their environment through preventive service, clinical care, research, and evaluation. WOEMA provides educational activities that work to enhance the professional capabilities of occupational and environmental medicine health care providers, and promote their life-long learning. WOEMA members are committed to assuring a safe work place, minimizing worker injury and illness, and serving as leaders, educators, collaborators and facilitators in preventing and resolving marketplace health problems. WOEMA is a regional component of the American College of Occupational and Environmental Medicine (ACOEM), and is dedicated to high quality medical care and ethical principles governing the practice of occupational medicine.
