Researchers worldwide will need further assistance to help comply with an increasing number of open data mandates, according to the authors of a new report.

The State of Open Data Report 2022 – the latest in an annual collaborative series from Digital Science, Figshare and Springer Nature – is released today.

Based on a global survey, the report is now in its seventh year and provides insights into researchers’ attitudes towards and experiences of open data. With more than 5,400 respondents, the 2022 survey is the largest since the COVID-19 pandemic began.

This year’s report also includes guest articles from open data experts at the National Institutes of Health (NIH), the White House Office of Science and Technology Policy (OSTP), the Chinese Academy of Sciences (CAS), publishers and universities.

Founder and CEO of Figshare Mark Hahnel says: “This year’s State of Open Data Report comes at a unique point in time when we’re seeing a growing number of open data mandates from funding organizations and policymakers, most notably the NIH and OSTP in the United States, but also recently from the National Health and Medical Research Council (NHMRC) in Australia, and in Europe and the UK.

“What is clear from the findings of our report is that while most researchers embrace the concepts of open data and open science, they also have some reasonable misgivings about how open data policies and practices impact on them. In an environment where open data mandates are increasing, funding organizations would benefit from working even more closely with researchers and providing them with additional support to help smooth the transition to a fully open data future.

“We all have a role to play in driving a better future for open data and accessible research, and one way we can do that through this report is by listening to the voices of researchers, funders, institutions, and publishers,” he says.

Primary findings from this year’s report indicated that:

• There is a growing trend in researchers being in favour of data being made openly available as common practice (4 out of every five researchers were in agreement with this), supported somewhat by now over 70% of respondents being required to follow a policy on data sharing.
• However, researchers still cite a key need in helping them to share their data as being more training or information on policies for access, sharing and reuse (55%) as well as long-term storage and data management strategies (52%).
• Credit and recognition were once again a key theme for researchers in sharing their data. Of those who had previously shared data, 66% had received some form of recognition for their efforts – most commonly via full citation in another article (41%) followed by co-authorship on a paper that had used the data.
• Researchers are more inclined to share their research data where it can have an impact on citations (67%) and the visibility of their research (61%), rather than being motivated by public benefit or journal/publisher mandate (both 56%).

Graham Smith, Open Data Program Manager, Springer Nature, says: “For the past seven years these surveys have helped paint a picture of researcher perspectives on open data. The report shows us not only the progress made but the steps that still need to be taken on the journey towards an open data future in support of the research community. Whether it’s the broad support of researchers for making research data openly available as common practice or the changing attitudes to open data mandates, we must learn from and deliver concrete steps forward to address what the community is telling us.

“Springer Nature is firmly committed to this and we continue to work closely with our partners, such as Figshare and Digital Science, to create better understanding around data sharing.”

Daniel Hook, CEO of Digital Science, says: “Digital Science is committed to making open, collaborative and inclusive research possible, as we believe this environment will lead to the greatest benefit for society. Now in its seventh year, while the articles in The State of Open Data Report represent a unique set of snapshots marking the evolution of attitudes about Open Data in our community, the data behind the survey constitutes a valuable resource to track researcher sentiment regarding open data and their experiences of data sharing. I believe that these data represent an amazing opportunity to understand the challenges and needs of our community so that we can collectively build better infrastructure to support research.”

Key findings via theme of the report

Support for open data

• Four out of every five respondents are in favour of research data being made openly available as common practice.
• 74% of respondents reported sharing their data during publication.
• Approximately one fifth of respondents reported having no concerns about sharing data openly – this proportion has been steadily growing since 2018.
• 88% of researchers surveyed are supportive of making research articles open access (OA) as a common scholarly practice.

Motivations and benefits

• When it comes to researchers sharing their data, citations of research papers (67%) and increased impact and visibility of papers (61%) outweigh public benefit or journal/publisher mandate (both 56%) as motivation.
• Of those who had previously shared data, 66% had received some form of recognition for their efforts – most commonly via full citation in another article (41%) followed by co-authorship on a paper that had used the data.
• A third of respondents indicated they had been involved in a research collaboration as a result of data they had previously shared.

Open data mandates

• 70% of respondents were required to follow a policy on data sharing for their most recent piece of research.
• More than two-thirds of respondents are supportive “to some extent” of a national mandate for making research data openly available. This number has been declining since 2019.
• Just over half (52%) of respondents in the 2022 survey felt that sharing data should be a part of the requirement for awarding research grants. Again, this number has been declining since 2019.

Drawbacks

• Only 19% of respondents believe that researchers get sufficient credit for sharing their data, while 75% say they receive too little credit.
• Just under a quarter of respondents indicated that they had previously received support with planning, managing or sharing their research data
• The greatest concern among respondents is misuse of their data (35%).
• The key needs of researchers which were felt more training or information would improve were better understanding and definitions for policies for access, sharing and reuse (55%) as well as long-term storage and data management strategies (52%) – things that impact both ends of the research cycle.

Key demographics of respondents

• Researchers from China now comprise 11% of all respondents, equal with that of the United States. China and the US are the two countries with the biggest response to the survey, followed by India, Japan, Germany, Italy, UK, Canada, Brazil, France and Spain.

• 31% of respondents were early career researchers (ECRs), while a further 31% classed themselves as senior researchers.

• Most respondents (42%) were from medicine & life sciences; 38% from mathematics, physics and applied sciences; and 17% from humanities and social sciences (an increase of 3%).

• Respondents were broadly categorised as: Open science advocates (32%), Open publishing advocates (26%), Cautiously pro open science (25%), Open science agnostics (11%), and Non-believers of open science (6%).

Heaviest element yet detected in an exoplanet atmosphere

Peer-Reviewed Publication

Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered the heaviest element ever found in an exoplanet atmosphere — barium. They were surprised to discover barium at high altitudes in the atmospheres of the ultra-hot gas giants WASP-76 b and WASP-121 b — two exoplanets, planets which orbit stars outside our Solar System. This unexpected discovery raises questions about what these exotic atmospheres may be like.

“The puzzling and counterintuitive part is: why is there such a heavy element in the upper layers of the atmosphere of these planets?” says Tomás Azevedo Silva, a PhD student at the University of Porto and the Instituto de Astrofísica e Ciências do Espaço (IA) in Portugal who led the study published today in Astronomy & Astrophysics.

WASP-76 b and WASP-121 b are no ordinary exoplanets. Both are known as ultra-hot Jupiters as they are comparable in size to Jupiter whilst having extremely high surface temperatures soaring above 1000°C. This is due to their close proximity to their host stars, which also means an orbit around each star takes only one to two days. This gives these planets rather exotic features; in WASP-76 b, for example, astronomers suspect it rains iron.

But even so, the scientists were surprised to find barium, which is 2.5 times heavier than iron, in the upper atmospheres of WASP-76 b and WASP-121 b. “Given the high gravity of the planets, we would expect heavy elements like barium to quickly fall into the lower layers of the atmosphere,” explains co-author Olivier Demangeon, a researcher also from the University of Porto and IA.

“This was in a way an ‘accidental’ discovery,” says Azevedo Silva. “We were not expecting or looking for barium in particular and had to cross-check that this was actually coming from the planet since it had never been seen in any exoplanet before.”

The fact that barium was detected in the atmospheres of both of these ultra-hot Jupiters suggests that this category of planets might be even stranger than previously thought. Although we do occasionally see barium in our own skies, as the brilliant green colour in fireworks, the question for scientists is what natural process could cause this heavy element to be at such high altitudes in these exoplanets. ​​“At the moment, we are not sure what the mechanisms are,” explains Demangeon.

In the study of exoplanet atmospheres ultra-hot Jupiters are extremely useful. As Demangeon explains: “Being gaseous and hot, their atmospheres are very extended and are thus easier to observe and study than those of smaller or cooler planets”.

Determining the composition of an exoplanet’s atmosphere requires very specialised equipment. The team used the ESPRESSO instrument on ESO’s VLT in Chile to analyse starlight that had been filtered through the atmospheres of WASP-76 b and WASP-121 b. This made it possible to clearly detect several elements in them, including barium.

These new results show that we have only scratched the surface of the mysteries of exoplanets. With future instruments such as the high-resolution ArmazoNes high Dispersion Echelle Spectrograph (ANDES), which will operate on ESO’s upcoming Extremely Large Telescope (ELT), astronomers will be able to study the atmospheres of exoplanets large and small, including those of rocky planets similar to Earth, in much greater depth and to gather more clues as to the nature of these strange worlds.

We design, build and operate world-class observatories on the ground — which astronomers use to tackle exciting questions and spread the fascination of astronomy — and promote international collaboration in astronomy. Established as an intergovernmental organisation in 1962, today ESO is supported by 16 Member States (Austria, Belgium, the Czech Republic, Denmark, France, Finland, Germany, Ireland, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom), along with the host state of Chile and with Australia as a Strategic Partner. ESO’s headquarters and its visitor centre and planetarium, the ESO Supernova, are located close to Munich in Germany, while the Chilean Atacama Desert, a marvellous place with unique conditions to observe the sky, hosts our telescopes. ESO operates three observing sites: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope and its Very Large Telescope Interferometer, as well as survey telescopes such as VISTA. Also at Paranal ESO will host and operate the Cherenkov Telescope Array South, the world’s largest and most sensitive gamma-ray observatory. Together with international partners, ESO operates APEX and ALMA on Chajnantor, two facilities that observe the skies in the millimetre and submillimetre range. At Cerro Armazones, near Paranal, we are building “the world’s biggest eye on the sky” — ESO’s Extremely Large Telescope. From our offices in Santiago, Chile we support our operations in the country and engage with Chilean partners and society.

Anti-anaerobic antibiotics associated with increased risk of mortality in critically ill patients

Study by U-M researchers shows early treatment with specific antibiotics depletes the body of gut anaerobes that protect against pneumonia, organ failure, and mortality.

Peer-Reviewed Publication

MICHIGAN MEDICINE - UNIVERSITY OF MICHIGAN

ANN ARBOR, MI – A common clinical practice may be inadvertently harming patients, according to new research published October 13 in the European Respiratory Journal. The team of Michigan Medicine researchers behind the study suggest that administration of antibiotics with activity against anaerobic bacteria has a profound effect on the gut microbiome and, ultimately, an adverse impact on critically ill patients.  

“We talk about the gut microbiome as a metabolic and immune ‘organ,’ and when we give patients anti-anerobic antibiotics, I worry we are causing a hidden form of organ failure,” said senior author Robert Dickson, M.D., Associate Professor in Pulmonary and Critical Care Medicine and Deputy Director at the Weil Institute for Critical Care Research and Innovation at the University of Michigan. “Our research suggests that depleting the gut of these ‘good bugs’ may be contributing to worse clinical outcomes.”

In the paper, researchers found that, in critically ill patients, the practice of early administration of anti-anaerobic antibiotics is commonplace – about two-thirds of the 3,032 patients observed in the study’s cohort received such treatment.

“For sick patients in the Emergency Department and Intensive Care Unit, there has been a lot of focus on ‘time-to-antibiotics’ as a quality improvement measure,” said Dickson. “Our results demonstrate that antibiotics really can’t be considered a single entity, as they have widely different impacts on the microbiome and on our patients. Patients who received anti-anaerobic antibiotics did far worse than patients who didn’t. We think that which antibiotic is given probably matters more than how quickly they are administered.”

With support from the Weil Institute, along with funding from the National Institutes of Health, the researchers conducted a retrospective single-center cohort study of 3,032 critically ill patients, comparing those who did and did not receive early anti-anaerobic antibiotics. By comparing ICU outcomes in all patients, and changes in gut microbiota in 116 of the patients, they found that those who received anti-anaerobic antibiotics early in their hospital course had worse outcomes, whether measured in overall survival, infection-free survival, or pneumonia-free survival.

The authors also found dramatic consequences of these antibiotics on the gut microbiome – during hospitalization, patients who received anti-anaerobic antibiotics had decreased initial gut bacterial density, followed by increased expansion and domination of the microbiome Enterobacteriaceae (a genus of common bacteria, many of which are pathogenic and cause opportunistic infections in immunocompromised hosts). These findings confirm that anti-anaerobic antibiotics have a dramatic effect on gut bacterial communities.

While the primary findings were from an observational study in humans, the team confirmed the results using animal modeling. In two different mouse models (pneumonia and oxygen-induced lung injury), animals who were treated with anti-anaerobic antibiotics did worse. Anti-anaerobic antibiotics increased the susceptibility of mice to pneumonia due to Enterobacteriaceae and increased their mortality from oxygen toxicity.

Co-author Rishi Chanderraj, M.D., a Clinical Lecturer in Infectious Diseases at U-M, was the lead researcher on the initial project and will be carrying the work forward in future studies.

“In observational studies, there is always a risk that a mortality difference is due to confounding; maybe the patients who received anti-anaerobic antibiotics were just sicker,” he said. “But the fact that we were able to recapitulate these findings in two different animal models gives us confidence that these findings are real.”

“No one wants to withhold antibiotics from patients with life-threatening infections,” said Chanderraj. “But our study confirms that the risk of overtreating with antibiotics isn’t just theoretical. I’m concerned that we’re harming our patients.”

Study questions the medical privacy of forensic samples

SF State researchers say databases used by law enforcement could contain private information about individuals, including crime victims

Peer-Reviewed Publication

SAN FRANCISCO STATE UNIVERSITY

Watch any episode of “CSI,” and a character will use forensic DNA profiling to identify a criminal. A new study from San Francisco State University suggests that these forensic profiles may indirectly reveal medical information — perhaps even those of crime victims — contrary to what the legal field has believed for nearly 30 years. The findings could have ethical and legal implications.

“The central assumption when choosing those [forensic] markers was that there wouldn’t be any information about the individuals whatsoever aside from identification. Our paper challenges that assumption,” said first author Mayra Bañuelos (B.S., ’19), who started working on the project as a San Francisco State undergraduate and is now a Ph.D. student at Brown University.

Law enforcement uses the Combined DNA Index System (CODIS), a system organizing criminal justice DNA databases that uses specific genetic markers to identify individuals. Crime labs from national, state and local levels contribute to these databases and provide profiles from samples collected from crime scene evidence, convicted offenders, felony arrestees, missing persons and more. Law officials can use the database to try to match samples found in an investigation to profiles already stored in the database.

CODIS profiles consist of an individual’s genetic variants as a set of short tandem repeats (STRs), sequences of DNA that repeat at various frequencies among individuals. Since the ’90s, 20 STRs have been chosen for forensic CODIS profiling specifically because it was believed they did not relay medical information. If these profiles contained any trait information, then there could be issues about medical privacy.

“But that assumption hasn’t had much investigation in a long time, and we know a lot more about the genome now than we did back then,” explained SF State Associate Professor of Biology Rori Rohlfs, who led this project.

The assumption that only criminals are sampled is also not completely accurate. “It actually also includes victims of crime and people that may have been at crime scenes. You have these huge databases including a lot of people that are not necessarily criminals,” Bañuelos said. “I believe also that accessibility to these databases varies a lot according to a jurisdiction.”

The researchers explained that other papers have found associations between other (non-CODIS) STRs and disease or gene expression. With that in mind, the SF State team wanted to understand the relationship between the CODIS STR markers and gene expression.

Rohfls’ lab used publicly available data (1000 Genome Project) and genetic models to investigate the relationship between CODIS markers and gene expression. Of the 20 CODIS markers, they found six associations between CODIS markers and gene expression of nearby genes in white blood cell lines from more than 400 unrelated individuals in the database.

“In some genes, gene expression change has been associated with medical conditions,” Bañuelos explained, citing prior research. “[In this study,] we indirectly know there is an association between these CODIS genotypes and some change in genes that can lead to illness.”

The authors note three associations to genes (CSF1R, LARS2, KDSR) that were particularly interesting. Prior literature shows that mutations and changes in gene expression of CSF1R can be tied to psychiatric conditions (depression and schizophrenia). Mutations and gene expression changes in the other genes have been connected to Perrault syndrome, MELAS syndrome, severe skin and platelet conditions and more, the scientists note in the PNAS (Proceedings of the National Academy of Sciences) paper. If CODIS markers can be connected to the expression of genes linked to disease and health, then it means that the data in the CODIS database could compromise an individual’s medical privacy.

“Our paper in some ways is like the tip of the iceberg,” Rohlfs said, admitting that she was surprised to find associations in a relatively small sample size. The project itself simply started as an undergraduate exploration project. Eight of the 11 authors were, like Bañuelos, undergraduates at SF State when the project began.

“It raises the question: If we did a more expansive [genetic] study, would we find even more information that would be revealed by CODIS profiles?” Rohlfs asked.

Bañuelos and Rohlfs are curious to know what they’d find if they looked at a larger dataset of more diverse populations — their current dataset is predominantly European. Their analysis was also limited to white blood cells. What relationships would they find if they looked in other tissues?

These are important lines of inquiry because the current dataset doesn’t represent the general population. Furthermore, Latino and African American communities are overrepresented in these CODIS databases, Bañuelos explained.

Additional studies are needed to better flush out the relationship between CODIS and medical information. However, the researchers point out that if CODIS profiles contain medical information, there could be major implications.

“If [these CODIS profiles] contain medical information, then their treatment would need to be consistent with the way we protect medical information in the United States. We would have to have policies that regulate the seizure, storage and sharing of these profiles,” Rohlfs added.

October 25, 2022

Key Points

Question  Are student sex and racial and ethnic identity associated with publication rate during medical school?

Findings  This cohort study of 31 474 medical school graduates found a significant disparity in publication rates across sex and race and ethnicity, with women and Black and Hispanic students reporting lower publication rates compared with men and White students. Sex and racial and ethnic disparities in research persisted at both National Institutes of Health top 40 and non–top 40 research-intensive schools.

Meaning  These findings suggest that inequities in the physician-scientist workforce began early in training, as exposure to research and research productivity are critical for a successful career as a physician-scientist.

Abstract

Importance  Diverse research teams are critical to solving complex health problems and producing high-quality medical research.

Objective  To examine the associations of student sex and racial and ethnic identity with publication rates during medical school.

Design, Setting, and Participants  This cohort study assessed individual-level data of US MD graduates from medical school who matriculated in academic years 2014 to 2015 and 2015 to 2016. Data were obtained from the Association of American Medical Colleges and analyzed from October 2021 to January 2022.

Main Outcomes and Measures  Outcomes of interest included students’ self-reported participation in unique research experiences, number of publications, and computed publications per research experience. Poisson regressions were constructed to determine the association of sex and racial and ethnic identity with research outcomes using adjusted rate ratios (aRRs).

Results  Among 31 474 graduates, 15 159 (48.2%) identified as women and 4344 (13.8%) identified as underrepresented in medicine by race and ethnicity (URIM; including American Indian, Alaska Native, Black, Hawaiian Native, Hispanic/Latinx, and Pacific Islander individuals). Students who attended National Institutes of Health (NIH) top 40 research-ranked schools reported higher number of research experiences and publication counts, resulting in a higher publication rate compared with students from non–top 40 schools (median [IQR] 1.60 [1.00-3.00] vs 1.25 [0.50-2.33]; P < .001). Women reported a higher number of research experiences than men but a significantly lower number of publications (top 40 schools: aRR, 0.89; 95% CI, 0.87-0.90; non–top 40 schools: aRR, 0.93; 95% CI, 0.92-0.95). This resulted in a significantly lower publication rate among women (top 40 schools: aRR, 0.85; 95% CI, 0.83-0.86; non–top 40 schools: aRR, 0.91; 95% CI, 0.90-0.92). Compared with White students, Asian students had higher publication rates at both NIH top 40 schools (aRR, 1.10; 95% CI, 1.08-1.12) and non–top 40 schools (aRR, 1.07; 95% CI, 1.05-1.08), while lower publication rates were reported among Black students (top 40 schools: aRR, 0.83; 95% CI, 0.80-0.86; non–top 40 schools: aRR, 0.88; 95% CI, 0.85-0.95) and Hispanic students attending non–top 40 schools (aRR, 0.93; 95% CI, 0.90-0.95).

Conclusions and Relevance  These findings illustrate that inequities in the physician-scientist workforce began early in training and highlight key areas for intervention, such as funding support and mentorship training during undergraduate medical education, that may promote the future success of a diverse physician-scientist workforce.

Current FDA oversight of vaping industry likely to have minimal impact

It’s failing to target key players and products most popular with young people

Peer-Reviewed Publication

BMJ

Current Food and Drug Administration (FDA) oversight of the vaping industry in the US is likely to have minimal impact, suggests an analysis of the regulator’s warning letters for marketing violations, published online in the journal Tobacco Control.

The regulator is failing to target the key players or the products most popular with young people, the analysis suggests, with over 90% of warnings sent to small online retailers rather than leading tobacco companies, and a focus on refillable devices.

While the prevalence of vaping among US adults remains low, at just under 4% in 2020, it is four times higher among young people.

In 2016 the FDA announced plans to regulate the vaping industry, including a requirement for the manufacturers of e-cigarettes to obtain pre-market approval (PMTA) to ensure that their products protect public health.

In 2017, the regulator began sending warning letters to manufacturers, retailers, and distributors for potential violations, such as advertising to young people, selling to minors, packaging or labelling that contravened regulations, and failure to apply for a PMTA.

But little is known about who received these letters, the types of product they concerned, or details of the violations and their consequences.

To try and find out, the authors from non-profit tobacco control organisation, Truth Initiative, assessed the content and recipients of publicly available FDA warning letters issued in 2020 and 2021. In total, the FDA issued 303 warnings:126 in 2020 and 177 up to 9 September 2021.

The analysis revealed that in 2021, over 98% of all the targeted companies fulfilled all three roles (manufacturer, distributor and retailer). 

But nearly all the letters (97%) were sent to small online retailers, none of which was a large company with measurable market share, as evidenced by sales data. 

Companies were cited for between one and three infractions. Most involved failure to obtain a PMTA. In 2020 and 2021, respectively, 56% and 99%+ of the infractions concerned a PMTA violation.

And more than 90% of the products cited–880 different ones in total–were flavoured refillable e-cigarette liquids, rather than the disposable vaping devices (‘pod mods’) which the evidence indicates are most popular with young people.

Penalties ranged in severity from product detention to product seizure and fines. But loss of tobacco distributor licence and criminal charges appeared less frequently in both years than these other consequences.

At the time of the review, most (72%) of the websites cited for 2020 infractions were still operating, as were 29% of websites cited for 2021 infractions.

And as the authors note, it was impossible to find out how the targeted companies responded, and whether the FDA followed through with the consequences cited in the warning letters, because that information isn’t publicly available.

“While current research estimates that online sales comprise around one-third of the marketplace, data tell us that most young people get their products from friends (32.3%), buy them from another person (21.5%), or purchase from a vape shop (22.2%),” note the authors.

“Prioritising the products most accessed by youth which are made available from a variety of sources will be important to curb youth use,” they add.

And they emphasise:“Strong, impactful and transparent consequences need to be in place to prevent the sale of products that violate regulations necessary in protecting the health of adult users of e-cigarettes and preventing youth use alike.”

“The FDA should use its enforcement powers to target the manufacturing, distribution, and sellers of the tobacco products that have the greatest impact on youth and products that provide no public health benefit,” they conclude.

New research shows e-cigarettes cause cardiac arrhythmias

Some cardiac effects of e-cigarette ingredients are similar to or worse than conventional cigarettes

A new study from University of Louisville researchers in the Christina Lee Brown Envirome Institute has found that exposure to e-cigarette aerosols can cause heart arrhythmias in animal models — both in the form of premature and skipped heart beats. The study findings, published Oct. 25 in Nature Communications, suggest exposure to specific chemicals within e-cigarette liquids (e-liquids) promote arrhythmias and cardiac electrical dysfunction.

“Our findings demonstrate that short-term exposure to e-cigarettes can destabilize heart rhythm through specific chemicals within e-liquids,” said Alex Carll, assistant professor in the UofL Department of Physiology who led the study. “These findings suggest that e-cigarette use involving certain flavors or solvent vehicles may disrupt the heart’s electrical conduction and provoke arrhythmias. These effects could increase the risk for atrial or ventricular fibrillation and sudden cardiac arrest.”

The researchers tested the cardiac impacts of inhaled e-cigarette aerosols solely from the main two ingredients in e-liquids (nicotine-free propylene glycol and vegetable glycerin) or from flavored retail e-liquids containing nicotine. They found that for all e-cigarette aerosols, the animals’ heart rate slowed during puff exposures and sped up afterwards as heart rate variability declined, indicating fight-or-flight stress responses. In addition, e-cigarette puffs from a menthol-flavored e-liquid or from propylene glycol alone caused ventricular arrhythmias and other conduction irregularities in the heart.

Conducted in collaboration with Daniel Conklin and Aruni Bhatnagar, professors in the UofL Division of Environmental Medicine, this work adds to a growing body of research on the potential toxicity and health impacts of e-cigarettes reported by the American Heart Association Tobacco Regulation and Addiction Center, for which UofL serves as the flagship institute.

"The findings of this study are important because they provide fresh evidence that the use of e-cigarettes could interfere with normal heart rhythms -- something we did not know before," Bhatnagar said. "This is highly concerning given the rapid growth of e-cigarette use, particularly among young people."

As e-cigarette use has grown nationwide, the potential advantages and harms of vaping have been debated. Since vaping does not involve combustion, it exposes users and bystanders to little if any carbon monoxide, tar or cancer-causing nitrosamines compared with conventional cigarettes. However, e-cigarettes can deliver aldehydes, particles and nicotine at levels comparable to combustible cigarettes. Vaping might help smokers quit combustible cigarettes, but the appeal and addictiveness of e-cigarettes may encourage youth to vape amidst unknown long-term risks or take up smoking. More than 25% of high schoolers and 10% of middle schoolers in the U.S. reported using e-cigarettes before the pandemic.

Additional research by Carll and Matthew Nystoriak, an associate professor of medicine at UofL, to determine the effects of vape flavorings on the heart recently received $3.6 million in research funding from the National Institutes of Health.

“Our team’s findings that specific ingredients in e-cigarette liquids promote arrhythmias indicates there is an urgent need for more research into the cardiac effects of these components in both animals and humans,” Carll said.
