  • WHO in no doubt

    WHO in no doubt

    E-cigarettes are “undoubtedly harmful,” according to a new report by the World Health Organization (WHO).

    “Although the specific level of risk associated with ENDS (electronic nicotine delivery systems) has not yet been conclusively estimated, ENDS are undoubtedly harmful and should therefore be subject to regulation,” the WHO wrote in its report.

    The report, funded by Bloomberg Philanthropies, also highlighted that progress has been made in the fight against tobacco, but more action is needed such as raising taxes, enforcing bans on advertising, and protecting others from tobacco smoke.

    The report showed that while only 23 countries have implemented cessation support policies at the highest level, 116 more provide fully or partially cost-covered services in some or most health facilities, and another 32 offer services but do not cost-cover them, demonstrating a high level of public demand for support to quit.

    Tobacco use has also declined proportionately in most countries, but population growth means the total number of people using tobacco has remained high. Currently, there are an estimated 1.1 billion smokers, around 80 percent of whom live in low- and middle-income countries.

  • Advocating scientific transparency

    Advocating scientific transparency

    Philip Morris International (PMI) has created an open online platform for sharing data, software and scientific protocols.

    Called Intervals, the platform has been built to address what PMI describes as a scientific reproducibility crisis, and gather in a single place scientific data relating to modified risk tobacco products, also known as reduced-risk products.

    Open to scientists from both academia and industry, and designed to enable third-party collaboration and analysis, Intervals follows the “FAIR” guiding principles for data sharing, i.e., data should be findable, accessible, interoperable and reusable.

    Scientists are encouraged to add their own independent research to Intervals, thereby contributing to transparency in the field and increasing the visibility of their work.

    “Across the life-sciences we see consistently low rates of the reproducibility of scientific research,” said Stéphanie Boué, scientific data transparency, PMI.

    “Sharing data in a way that enables reanalysis and reuse is not yet done in a systematic manner, despite the fact that doing so would clearly benefit the scientific community and society in general.

    “This is particularly true where the quality of science may be questioned due to the affiliations of researchers, funding sources or research topics. Tobacco harm reduction is one such area, and Intervals is a crucial resource to ensure full transparency and reproducibility of the scientific research being conducted in the field.”

    Intervals includes full, standardized and extensively annotated datasets from a number of clinical and pre-clinical studies that PMI has conducted as part of the assessment of its MRTPs. These range from large in vivo inhalation studies, to novel in vitro studies using three-dimensional human tissue cultures, to clinical studies investigating the pharmacokinetics of different nicotine delivery systems.

    The platform provides detailed information on study protocols and interoperable data files that allow independent reanalysis of key findings, meta-analyses and efficient data reuse. Alongside raw data, rich metadata are also provided to describe experiments, data production, data processing and additional relevant information. Each study, protocol, and dataset are assigned a unique DOI, making them easily findable and citable.

    Many of the PMI-conducted studies that are included on Intervals have been reviewed through a novel and comprehensive panel review process organized independently by SciPinion of Bozeman, Montana, USA.

    This has been done in addition to the traditional peer-review of study publications. Seven panels of five to 12 anonymous experts scrutinized publications and raw data, resulting in consistent support of the robustness of methods and results, and the validity of conclusions. Intervals facilitates such detailed reviews, allowing any interested party to independently evaluate data, methodologies and conclusions. In doing so, the platform is able to contribute to the review processes of regulatory bodies such as the U.S. Food and Drug Administration, while also allowing the reuse of data in the generation and testing of new hypotheses.

    Scientists who wish to add their own research and data to Intervals can do so with no word or figure limit. Storage space is virtually unlimited, and they will be assigned DOIs as appropriate for the individual aspects of their contributions.

    By sharing their research in the standardized Intervals format, scientist have the opportunity to make their data part of future meta-analyses and contribute to a new vision and strategy for transparency and reproducibility. Intervals also includes direct links to a number of powerful computational tools and resources, which are free for contributors to use for their own research purposes.

    “Intervals is set to become an international hub for scientists with a common interest in tobacco harm reduction,” said Manuel C. Peitsch, chief science officer, PMI. “This includes scientists from industry, academia, not-for-profit research organizations and regulatory bodies. In working collectively, and with a commitment to transparency and reusability, the community can establish standards in data sharing and management which will lead to the optimization of research funds and the leveraging of research findings to enable effective evidence-based decision making.”

    According to PMI, the need for innovative and concerted efforts to improve reproducibility is being increasingly acknowledged across the scientific community. The U.S. National Academies of Science, Engineering, and Medicine has recently published a report—Reproducibility and Replicability in Science—calling on researchers to “convey clear, specific, and complete information about any computational methods and data products that support their published results.” The Intervals concept can be applied in many other areas of societal concern. According to PMI, any field that deals with large and complex data could benefit from this approach as the issues concerning transparency, data reusability and reproducibility are general across the sciences.

     

  • Conclusions questioned

    Conclusions questioned

    Brad Rodu

    Brad Rodu, a University of Louisville professor, has asked the Journal of the American Heart Association to retract a recent study by Stanton Glantz, a professor of medicine at the University of California at San Francisco (UCSF).

    The study, co-authored by Dharma Bhatta, associates adult vaping with a doubled risk of heart attack.

    However, when Rodu examined the data, he found the majority of the 38 patients in the study who had heart attacks had them before they started vaping—by an average of 10 years earlier.

    Glantz retorted that Rodu has a history of “slicing and dicing” his and other’s research “to make effects go away.”

    Glantz calls Rodu a “tobacco industry apologist” and points to documents UCSF has collected that show Rodu’s connections to the tobacco industry.

    Rodu says he sought industry funding after the National Cancer Institute treated him as if he was unethical to suggest that smokeless tobacco was safer than cigarettes when he applied for funding there in 1995.

    The spat between the researchers is detailed in USA Today.

  • Gateway leads nowhere

    Gateway leads nowhere

    The Philippines’s Department of Health (DOH) is stubbornly refusing to consider the growing body of evidence supporting electronic cigarettes as comprising a less harmful alternative to combustible cigarettes and an effective smoking cessation aid, according to an opinion piece by Mary Ann LL. Reyes published in The Philippine Star.

    Health Undersecretary Eric Domingo was said recently to have reiterated the DOH’s warning that the use of e-cigarettes was not a good alternative to cigarette smoking and that, because e-cigarettes contained nicotine, the DOH was concerned that vapers would become addicted to nicotine and then become cigarette smokers.

    Reyes said that Domingo’s statement was hardly surprising. The DOH followed the World Health Organization position that the only way to reduce smoking was for smokers to quit or die, and that anything less than an abstinence-only approach was unacceptable. Like the WHO, the DOH was highly skeptical of the potential for new technologies, such as e-cigarettes, to reduce smoking-related harms.

    What was worrying, Reyes wrote, was the DOH’s stubborn refusal to consider the growing body of evidence supporting e-cigarettes as a less harmful alternative to conventional cigarettes and an effective smoking cessation aid.

    February 27 had seen the publication by Public Health England of its latest evidence update summary on vaping.

    One of the updated evidence review’s key findings immediately stood out because it ran completely counter to Domingo’s statement. E-cigarettes were not a gateway to smoking.

    The evidence showed that e-cigarette use in the UK remained largely confined to those who already smoked or ex-smokers who had now quit using an e-cigarette, while quitting smoking remained the key motivation among adult vapers. The fear that the number of young people using e-cigarettes regularly would increase sharply was not happening in the UK. While experimentation was increasing, vaping among young people remained low at 1.7 percent and was mainly confined to those who already smoked.

  • Pregnant finding

    Pregnant finding

    Researchers at the Department of Drug Design and Pharmacology of the University of Copenhagen, Denmark, say that tobacco smokers who become pregnant cannot protect their fetuses sufficiently by undertaking a quit-tobacco-smoking course, according to a story by Stephen Gadd for The Copenhagen Post.

    “When a pregnant woman uses nicotine chewing-gum or any other form of nicotine substitute in connection with stopping smoking, she risks damaging her fetus as much as if she’d continued to smoke,” associate professor and brain researcher Jesper Tobias Andreasen, was said to have told BT tabloid.

    The negative effects were said to be caused by nicotine’s reducing the flow of blood through the placenta leading to the fetus not receiving enough oxygen to the brain. This could cause conditions such as ADHD, anxiety, depression and addictive tendencies later in life.

    Andreasen points out that a ‘stop smoking’ course is all very well but the only safe way to do it is to go ‘cold turkey’ – without any form of nicotine substitutes.

    Vaping was said also to present a risk to the fetus because the levels of nicotine in the liquids used contained ‘very variable amounts and often more than normal cigarettes’.

    Up to now, the Copenhagen research has been carried out on mice. But Andreasen said that it was known “from extensive studies that people who have been exposed to nicotine in the womb show a higher propensity to ADHD, anxiety, depression and drug abuse”.

    The researchers say they intend to publish their findings in a scientific journal within the next couple of months.

     

  • A means to an ENDS

    A means to an ENDS

    The Broughton Group said yesterday it had launched Broughton Nicotine Services, a spin-off from Broughton Laboratories that will specialise in ‘accelerating safer nicotine-delivery products to market; advancing a smoke-free future’.

    ‘The launch coincides with the development of a 15,000 ft2 CRO [contract research organization] facility (pictured – Karen Ross Photography Studio) in Lancashire [UK] designed specifically to address the needs of the Electronic Nicotine Delivery Systems (ENDS) market,’ Broughton said in a press note.

    ‘Having operated in this rapidly expanding and changing market for almost 10 years, the company is now perfectly placed to guide ENDS companies through a period of growth and regulatory change.

    ‘Broughton Nicotine Services raised over £5 million in 2018 to invest in the new facility which includes several specialist laboratories equipped with the latest aerosol collection instruments, high-spec analytical equipment and fully validated software data management systems.

    ‘An impressive stand-alone stability facility covering all ICH [International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use] storage requirements has been included in this initial phase of developments.

    ‘Led by a growing team of experienced scientists and analytical chemists, the operation is aligned with capacity for further expansion during 2019 to meet the expectations of its global client base.’

    Chief executive Dr. Paul Moran was quoted as saying that there had been a rapid change during recent years within the reduced-risk nicotine products market. “At Broughton Nicotine Services, we are committed to supporting this evolving industry towards creating a smoke-free future through innovations, scientific advancement and regulatory compliance,” he said. “Operating as an independent company within the Broughton Group, specialising in next generation nicotine delivery, will enable us to continue to accelerate the transformation of this exciting industry for our clients.”

  • Looking for change

    Looking for change

    Knowledge∙Action∙Change (KAC), a private sector public health agency based in the UK, has called for action to prevent the dramatic rises in smoking rates in Africa that have been predicted by the World Health Organization.

    In a note issued through PRNewswire, KAC said that while globally smoking rates were decreasing, in many lower- and middle-income countries, African nations among them, rates were increasing. WHO data showed a steep rise in smoking in many African countries, with many five-year projected increases at five percent and more.

    With this in mind, public health experts from KAC had this week visited Lilongwe, Malawi, and Nairobi, Kenya, to launch No Fire, No Smoke – The Global State of Tobacco Harm Reduction 2018 (GSTHR), ‘a landmark report on the worldwide availability, regulation, and use of lower-risk alternatives to tobacco, such as e-cigarettes (vapes), heat-not-burn devices, and Swedish snus (pasteurized oral tobacco)’.

    ‘A proven public health strategy, harm reduction refers to policies, regulations, and actions that reduce health risks by providing safer forms of hazardous products or encouraging less risky behaviors, rather than simply banning them,’ the note said.

    ‘Independent evidence from the UK Government’s leading public health body demonstrated recently that vaping is at least 95 percent safer than smoking tobacco. Yet despite the WHO Framework Convention on Tobacco Control (FCTC) of 2003 citing harm reduction as one of its main tactics, the WHO has been persistently negative about e-cigarettes, has called for their ban or strict regulation, and sees them as a threat, rather than as a public health opportunity.

    ‘Partnering with the information dissemination project, Tobacco Harm Reduction Malawi, and the newly launched Campaign for Safer Alternatives based in Kenya, the GSTHR report’s publishers presented global findings on tobacco harm reduction, showing that many smokers have switched to safer products and dramatically reduced the risks associated with smoking.’

    “We need to halt the dramatic rises in smoking rates in Africa which are predicted by WHO,” Professor Gerry Stimson, director of KAC and Emeritus Professor at Imperial College London, was quoted as saying. “Most smokers want to quit smoking, but they find it hard to stop using nicotine. Around the world, millions of lives depend on both consumer and government acceptance of safer alternatives to smoking.”

    Meanwhile, Chimwemwe Ngoma, project manager, Tobacco Harm Reduction Malawi and holder of a Global Tobacco Harm Reduction Scholarship, said that Tobacco Harm Reduction Malawi believed that all citizens of Malawi should be informed of the health consequences, addictive nature, and mortal threat posed by tobacco consumption and exposure to tobacco smoke. “Malawians should be able to make more informed public and personal choices, including having access to safer nicotine products, to enable them to live longer and healthier lives,” he said.

    And Joseph Magero, chair of the Campaign for Safer Alternatives and holder of a Global Tobacco Harm Reduction Scholarship, said society’s relationship with tobacco and nicotine was changing due to technical developments in vaping devices and other safer nicotine products. “The Campaign for Safer Alternatives has formally launched this week to ensure more people across East Africa receive accurate information on alternatives to smoking,” he said. “By arming people with information, we can finally begin to curb the tobacco epidemic.”

  • That’s some ‘problem’

    That’s some ‘problem’

    A public health expert in the US has set out to answer a question that has probably popped into many heads in recent times: why does vaping seem so threatening to the tobacco control movement?

    Writing on his blog, The Rest of the Story, Dr. Michael Siegel (pictured), a Professor in the Department of Community Health Sciences, Boston University School of Public Health, starts off by saying that he and his colleagues in the tobacco control movement had based their entire careers on the principle that it was wrong to lie to the public.

    On the other hand, much of their campaign against Big Tobacco had been based on the contention that cigarette companies lied to the public about the health risks of smoking.

    However, Siegel said he believed that during the past few years the tobacco control movement had largely abandoned truth as a central value in so far as its campaigns against vaping were concerned.

    Why is vaping so threatening to the tobacco control movement? he asks. Is it threatening because it is extremely dangerous – basically as harmful as smoking – and is therefore harming the health of the nation’s 11 million adult vapers?

    No, he replies to his own question; it’s precisely the opposite…

    ‘The problem with vaping is that it is not killing anyone, so there is no punishment for the vice of being addicted to nicotine,’ he said. ‘And that’s something that the tobacco control movement can simply not tolerate.’

  • Focus on young people

    Focus on young people

    British American Tobacco has said that it will continue to work with the US Food and Drug Administration as the agency advances new policies aimed at preventing youth access to flavored tobacco products.

    The FDA Commissioner Scott Gottlieb, MD, yesterday made a statement on preventing young people from obtaining such products; as described on this website yesterday under the heading Haste urged.

    “We welcome the FDA … shining a spotlight on the important issue of youth access to vapor products,” a BAT spokesperson was quoted as saying in a note posted on the company’s website. “We have always been clear that youth should not use vapor products and have had stringent measures in place to address this for some time.

    “In relation to today’s announcement, we share the FDA’s concerns that some flavors, such as those resembling ‘kid-friendly’ food products, may play a role in increasing youth appeal and that marketing activities should not be directed to youth. We have never marketed such vapor flavors; we have supported measures to remove vapor products intended to mimic children’s food products or otherwise designed to target youth and have procedures in place to ensure our products are only marketed to adult tobacco consumers.

    “We believe flavors are important in helping adult smokers migrate away from cigarettes, and the flavors we market are directed at helping adult smokers who are looking for a potentially less harmful alternatives to cigarettes.

    “We already have third-party age verification processes for online sales. We will work with our many convenience retailers to ensure that tobacco, mint and menthol, which are our top selling flavours, remain available for consumers who are looking for potentially less harmful alternatives to cigarettes. We also have plans to make our flavored products available in other age restricted locations, including in specialist vape stores. As with all our retail partners, we will work with any new partners who stock our products to ensure they have appropriate age verification mechanisms.

    “In respect of the proposals on bringing forward the PMTA [FDA pre-market tobacco applications] date for flavored products, given our years of product development and scientific assessment of our vapor products, we are well-positioned to file PMTAs for our VUSE products and plan to do so ahead of the 2021 deadline.

    “We will continue working with the FDA as the agency moves this proposed compliance change forward over the coming weeks. We will be submitting comments for the FDA to review and consider as the agency works to finalise the guidance document.”
