Environmental exposures and Parkinson’s disease: connecting the dots: Interview with Dr. Ray Dorsey and Dr. Rick Woychik (Director of NIEHS)

Monday, December 5, 2022

Dr. Rick Woychik, the Director of the National Institute of Environmental Health Sciences (NIEHS), and Dr. Ray Dorsey spoke about how air pollution, certain pesticides, and other agents may be contributing to rising rates of the disorder.  

At this year’s meeting of the American Neurological Association, held in late October, Dr. Woychik helped to moderate a plenary session titled “Neurologic Dark Matter: Exploring the Exposome that Drives Neurological Disorders.” The exposome refers to all of the exposures experienced by an individual throughout life and their corresponding biological effects. Ray Dorsey, M.D., argued that when it comes to causes of Parkinson’s disease, scientists should focus on the role of multiple environmental toxicants, such as air pollution and pesticides, rather than genetics alone.

Banning Fruity Flavors Did Not Deter Vapers

Wednesday, November 30, 2022

Adults did not quit vaping in response to FDA ban of flavored e-cigarettes

Deborah OssipOn February 6, 2020, the U.S. Food and Drug Administration banned the sale of many flavored e-cigarettes, with some important exceptions. According to a survey conducted by University of Rochester Medical Center (URMC) researchers, the ban did not result in adults quitting e-cig use and may have driven some back to smoking regular cigarettes. The researchers point to policy loopholes as the main reasons the policy failed to push people to quit.

Survey results, published in Tobacco Controlshow that less than five percent of the 3,500 adult e-cig users who responded to the survey quit using e-cigs in response to the flavored e-cig ban. The rest of the respondents switched to other forms or flavors of e-cigs not covered by the ban or other types of tobacco products.

“An increasing body of literature shows that e-cig flavors themselves cause damage when inhaled, so it makes sense to ban flavors,” said Deborah J. Ossip, Ph.D., a tobacco research expert and professor in the Department of Public Health Sciences and Center for Community Health and Prevention at URMC who co-authored the study. “But the ban doesn’t appear to be working. People – including youth – can still get flavored products and are still using them.”

A One-Two Punch: Low Levels of Coffee Roasting Chemical and Mild Flu May Damage Lungs

Monday, October 10, 2022

We’ve known for two decades that chronic exposure to high levels of a flavoring chemical called diacetyl, which is found in many foods and beverages, can cause lung damage. Now, a University of Rochester Medical Center study suggests that even short-term exposures to this flavoring chemical can damage the lungs of mice when paired with a second insult, like the flu.

Diacetyl, which gives microwave popcorn its buttery flavor, was first linked to flavorings-related lung disease in the early 2000’s when a group of former microwave-popcorn factory workers came down with the illness. More recently, a similar lung disease has been seen among coffee roasters who inhale large concentrations of diacetyl, which is a natural byproduct of the coffee roasting process.

While those workers inhaled high levels of diacetyl over long periods of time, the URMC study published in the American Journal of Physiology – Lung Cellular and Molecular Physiology set out to test whether low-level, short-term exposures to the same chemical could produce a similar effect.

“We found that a single exposure to diacetyl for short periods of time did not result in much lung damage,” said lead study author Matthew D. McGraw, M.D., assistant professor of Pediatric Pulmonology at URMC. “But when mice are exposed to another common environmental exposure, like flu, the double hit can cause airway disease similar to what we see with high-dose, long-term exposures to diacetyl.”

In the study, which was supported by a pilot grant from the URMC Environmental Health Science Center and a Career Development Award from the UR Clinical and Translational Science Institute, mice were exposed to diacetyl for one hour a day over five consecutive days at levels similar to what coffee roasters encounter at work. Mice were then exposed to influenza A, which typically causes seasonal flu in humans.

Within two weeks of exposure, more than half of the mice that received this one-two hit died, while all of the mice in the control groups (exposed to diacetyl alone, flu alone, or neither) survived. Lungs from mice exposed to the ‘two-hits’ showed significant impairment of lung function and airway repair compared to controls.

Researchers then switched the order of exposure, infecting another group of mice with flu first, allowing them to recover for nine days, then exposing them to diacetyl for five days. Whether the mice were exposed to diacetyl before or after flu, their lungs were unable to fully heal, again suggesting that exposure to both chemical and virus leads to abnormal airway repair.

"Our study shows that common environmental exposures that seem harmless on their own can have very serious impacts on lung function and long-term respiratory health when combined," McGraw said.

While further research is needed to understand the impacts of low levels of diacetyl on humans, this study could have implications for people who are exposed to diacetyl at work, like coffee roasters. Currently, McGraw’s team is conducting a study in mice to see how long after a flu infection it is safe to be exposed to diacetyl, which could help inform when coffee roasters can safely return to work after having the flu.

In the near future, the team also plans to collaborate with coffee roasters in our region to spread awareness of the risks of diacetyl exposure, assess existing exposure mitigation procedures, and survey workers for lung disease symptoms.

Other authors of the American Journal of Physiology – Lung Cellular and Molecular Physiology study include Michael A. O’Reilly, Ph.D., professor of Pediatrics; B. Paige Lawrence, Ph.D., chair and professor of Environmental Medicine; Andrew M. Dylag, M.D., associate professor of Pediatrics; Min Yee, a technical associate in the O’Reilly lab; and So-Young Kim, M.S., a technician in the McGraw lab.

This project was supported by a pilot grant from the URMC Environmental Health Science Center under grant number P30 ES001247 from the National Institute of Environmental Health Sciences and by the University of Rochester CTSA award number KL2 TR001999 from the National Center for Advancing Translational Sciences.

Meet Five Inspiring Women in Science

Friday, February 11, 2022

URMC Researchers Reflect on International Day of Women and Girls in Science.

Be curious and inquisitive. Cultivate relationships with mentors. Never limit yourself. Follow your heart.

These are just a few pieces of advice that women researchers from across the University of Rochester Medical Center have for young women and girls interested in science.

Despite progress in recent years, women and girls from around the world are still less likely to enter and advance in science, technology, engineering and math (STEM) fields. According to the United Nations, female researchers are typically awarded smaller research grants, are less likely to have their work published by high-profile journals, and have shorter careers than their male colleagues.

And the COVID pandemic has only exacerbated these disparities as the burden of care in the home fell disproportionately to women.

To combat these disparities, the United Nations General Assembly declared February 11 the International Day of Women and Girls in Science in 2015. Today, we celebrate the work and achievements of women in STEM and promote full and equal access to STEM for women and girls the world over.

Wastewater-based epidemiology comes of age during pandemic

Wastewater sampling provides noninvasive, cost-effective tool for tracking disease prevalence and spread, say experts at NIEHS event.

Katrina Korfmacher, Ph.D., from the University of Rochester, said that at the start of the pandemic, historically disadvantaged communities in upstate New York were disproportionately affected by the virus.

“We thought wastewater monitoring in communities with low testing rates could counteract inequities in the pandemic response by determining where resources were needed,” she said.

A first step was to develop capacity, understanding, and experience within local institutions. So, Korfmacher helped assemble a coalition of local governments and colleges to sample wastewater.

Results from surveillance of student populations allowed colleges to implement strong public health rules, such as closing in-person instruction, without having to track down individual students for testing.

“Wastewater was a valuable part of our overall testing system,” she told attendees.
