Tobacco Industry Linked to Disproven COVID ‘Protective Effect’ of Nicotine

An investigation by The BMJ uncovered undisclosed financial links between certain authors and the tobacco and e-cigarette industry in a number of COVID research papers, which had suggested that smokers were less likely to develop COVID. 

In April 2020, two French studies (in preprint and not yet peer reviewed) suggested that nicotine might have a protective effect against COVID, which was coined the ‘nicotine hypothesis’.

The studies were reported on widely by the media, causing fears that it could undermine decades of tobacco control. What should have been an opportunity for promoting cessation of this practice which every year kills five million people around the world.

Since then, the ‘nicotine hypothesis’ has been soundly disproved, with several studies showing that, to the contrary, smoking is associated with an increased chance of COVID related death.

Journalists Stéphane Horel and Ties Keyze investigated the circumstances of these reports. They pointed out that one of the study authors, Professor Jean-Pierre Changeux, has a history of receiving funding from the Council for Tobacco Research, whose purpose was to fund research that would cast doubt on the dangers of smoking and focus on the positive effects of nicotine.

From 1995 to 1998, documents from the tobacco industry show that Changeux’s laboratory received $220,000 (£155,000; €180,000) from the Council for Tobacco Research.

When approached by The BMJ, Changeux assured them that he has not received any funding linked “directly or indirectly with the tobacco industry” since the 1990s.

In late April 2020, Greek researcher Konstantinos Farsalinos was the first to publish the ‘nicotine hypothesis’ formally in a journal, in an editorial in Toxicology Reports.

That journal’s editor in chief, Aristidis Tsatsakis was a co-author, as was A Wallace Hayes, who in 2013 had been a member of Philip Morris International’s scientific advisory board, and had served as a paid consultant to the tobacco company.

Another co-author is Konstantinos Poulas, head of the Molecular Biology and Immunology Laboratory at the University of Patras, where Farsalinos is affiliated.

The laboratory has been receiving funding from Nobacco, the market leader in Greek e-cigarettes and the exclusive distributor of British American Tobacco’s nicotine delivery systems since 2018. However, in their published scientific articles, neither Farsalinos nor Poulas had ever declared this Nobacco funding.

Yet the journalists showed that two grants were attributed in 2018 by the Foundation for a Smoke Free World—a non-profit established by tobacco company Philip Morris International in 2017—to ‘Patras Science Park’.

The grants, which according to tax documents came close to €83 000, went to NOSMOKE, a university start-up incubator headed by Poulas, which markets an ‘organic’ vaping product.

Last month, the European Respiratory Journal retracted a paper with Poulas and Farsalinos as co-authors, after two other authors failed to disclose conflicts of interest.

The retracted article had found that “current smoking was not associated with adverse outcome” in patients admitted to hospital with COVID, and it claimed that smokers had a significantly lower risk of acquiring the virus.

The foundation has invested heavily in the COVID/nicotine hypothesis, said Horel and Keyzer.

In June 2020 it set aside €900 000 for research “to better understand the associations between smoking and/or nicotine use, and COVID-19 infection and outcome.”

Its request stated that the pandemic offered “both an opportunity and a challenge for individuals to quit smoking or transition to reduced risk nicotine products.”

They concluded that, in 2021, “amid a global lung disease pandemic, tobacco industry figures are increasingly pushing the narrative of nicotine as the solution to an addiction that they themselves created, with the aim of persuading policy makers to give them ample room to market their “smoke-free” products. This makes studies on the hypothetical virtues of nicotine most welcome indeed.”

US Supreme Court Snubs Johnson & Johnson Talc Lawsuit Appeal

On Tuesday, the US Supreme Court declined to hear Johnson & Johnson’s appeal challenging a $2.12 billion ruling in favour of 20 women who developed ovarian cancer which they alleged was linked to the company’s talcum powder. 

The company was appealing a 2018 court ruling in favor of 22 women who alleged asbestos-contaminated talcum powder was linked to their cases of ovarian cancer. The women had said the company did not provide adequate warning of the risks associated with using their products. The initial settlement amount had initially been over $4 billion before being cut down.

The judge in that case ruled Johnson & Johnson had “misrepresented the safety of these products for decades” and the evidence shown at the trial demonstrated “particularly reprehensible conduct on the part of Defendants.”
Johnsons & Johnson has dominated the talcum powder market for over a century.
While there is no established link between talcum powder exposure and cancer, but talcum powder is often mined close to asbestos, a known carcinogen for which there is no safe level of exposure, and which can have a long latency period between exposure and cancer development.
Some studies have shown an increase in lung cancer risk for miners working underground when exposed to raw talc, which can be contaminated with asbestos, while others have found no effect. Use of talcum powder in the genital or perineal area is thought to contribute to ovarian cancer risk, but results are also mixed.
Companies have been directed not to use asbestos in cosmetic products since the 1970s, according to the American Cancer Society. According to the National Cancer Institute, “the weight of evidence does not support an association between perineal talc exposure and an increased risk of ovarian cancer.”


A 2018 investigation by Reuters uncovered documents showing that Johnson & Johnson was not only aware of the asbestos contamination problem, the company covered it up. It even tried to influence US regulatory policy over asbestos in cosmetic products. Lawyers representing the company have argued in court that the tests were unreliable, although recent independent lab tests of samples obtained from various time periods detected asbestos contamination.

In response to queries from Reuters, Johnson & Johnson’s outside litigation counsel Peter Bicks wrote: “The scientific consensus is that the talc used in talc-based body powders does not cause cancer, regardless of what is in that talc. This is true even if – and it does not – Johnson & Johnson’s cosmetic talc had ever contained minute, undetectable amounts of asbestos.”

Human-monkey Chimeric Embryos Set off Ethics Debate

A study published in the journal Cell has announced the creation of human-monkey chimeric embryos, igniting renewed debate over ethics.

The embryos are known as chimeras, organisms whose cells come from two or more “individuals”, and in this case, different species: a long-tailed macaque and a human. The research confirmed that the cells can survive and multiply.

Natural human chimeras do exist, and can involve humans cells from two embryos in the same womb fusing to produce a single individual, or a combination of maternal and foetal cells, or monozygotic twins sharing blood cells from a shared placenta.

Previously, researchers had produced pig or sheep embryos that contained human cells, in an effort to one day develop a way to grow human organs for transplant inside the animals.

The researchers, led by Prof Juan Carlos Izpisua Belmonte from the Salk Institute in the US, said that the results shed new light on the communications pathways between cells of different species. This could help with future efforts to engineer chimeras using more distantly related species.

“These results may help to better understand early human development and primate evolution and develop effective strategies to improve human chimerism in evolutionarily distant species,” the authors wrote.

In 2019, the Spanish newspaper El País reported on rumours that a team of researchers led by Belmonte had created monkey-human chimeras.

Specific human foetal cells called fibroblasts were reprogrammed to become stem cells, and were then introduced into 132 embryos of long-tailed macaques, six days after fertilisation.

“Twenty-five human cells were injected and on average we observed around 4% of human cells in the monkey epiblast,” said Dr Jun Wu, a co-author of the research, and now at the University of Texas Southwestern Medical Center.

The embryos were grown in petri dishes and were terminated 19 days after the stem cells were injected. The human cells were engineered with a fluorescent protein to enable identification.

The researchers reported that 132 embryos contained human cells on day seven after fertilisation. However, the proportion containing human cells fell over time.

“We demonstrated that the human stem cells survived and generated additional cells, as would happen normally as primate embryos develop and form the layers of cells that eventually lead to all of an animal’s organs,” Belmonte said.

The researchers also found differences in intercellular interactions between human and monkey cells within chimeric embryos, compared to the normal monkey embryos.

The researchers hoped the research would help develop “transplantable human tissues and organs in pigs to help overcome the shortages of donor organs worldwide”, said Wu.

Prof Robin Lovell-Badge, a developmental biologist from the Francis Crick Institute in London, said at the time of the El País report he was not concerned about the ethics of the experiment, noting the team had only produced a ball of cells. But he noted conundrums could arise in the future should the embryos be allowed to develop further.

While not the first attempt at making human-monkey chimeras – another group reported such experiments last year – the new study has reignited such concerns. Prof Julian Savulescu, the director of the Oxford Uehiro Centre for Practical Ethics and co-director of the Wellcome Centre for Ethics and Humanities at the University of Oxford, said the research had raised all sorts of ethical concerns.

“These embryos were destroyed at 20 days of development but it is only a matter of time before human-nonhuman chimeras are successfully developed, perhaps as a source of organs for humans,” he said, and added that a key ethical concern was the moral status of such organisms.

“Before any experiments are performed on live-born chimeras, or their organs extracted, it is essential that their mental capacities and lives are properly assessed. What looks like a nonhuman animal may mentally be close to a human,” he said. “We will need new ways to understand animals, their mental lives and relationships before they are used for human benefit.”

Others were less concerned, and rather pointed out that all the study found was that the creation of such chimera was simply ineffective.

Dr Alfonso Martinez Arias, an affiliated lecturer in the department of genetics at the University of Cambridge, said: “I do not think that the conclusions are backed up by solid data. The results, in so far as they can be interpreted, show that these chimeras do not work and that all experimental animals are very sick.

“Importantly, there are many systems based on human embryonic stem cells to study human development that are ethically acceptable and in the end, we shall use this rather than chimeras of the kind suggested here.”

A Public Archive for Opioid Lawsuit Information

In order to improve transparency about the opioid crisis,  the University of California San Francisco and Johns Hopkins University launched a digital public archive of documents from lawsuits against drug manufacturers.

The digital repository of publicly disclosed legal documents related to the crisis allows free, public access to anyone interested in the continuing litigation and uncovered evidence.

“All too often, the public never gets the benefit of seeing and learning from litigation that generally takes place behind closed doors,” said Caleb Alexander, MD, a professor of epidemiology and medicine at Johns Hopkins and the founding co-director of the Center for Drug Safety and Effectiveness, which will assist in maintaining the archive.

“Our focus is to be sure that the millions of pages of documents arising from opioid litigation ultimately see the light of day,” Alexander told MedPage Today. “We owe it to all those who have been impacted — especially patients and their loved ones — to see to it that these materials are placed in the public domain.”

The goal of the archive is to provide transparency into the methods used by drug companies to increase opioid sales, which led to the opioid epidemic in which, according to the CDC, over the past two decades, nearly 500 000 Americans died of overdoses involving an opioid. Additionally, the economic cost of the crisis in 2015-2018 was put at $2.5 trillion by the White House Council of Economic Advisers.

Most of the archive’s documents were released thanks to efforts by the Washington Post and the Charleston Gazette. Records include company emails, memos, presentations, sales reports, audit reports, budgets, Drug Enforcement Administration briefings, expert witness reports, and depositions of drug company executives.

The archive is located on a website called Drug Industry Archives, a UCSF project that houses documents illustrating how the pharmaceutical industry, academic institutions, continuing medical education organizers and regulatory agencies impact public health. (UCSF also maintains similar archives related to tobacco, food, chemicals, and fossil fuel industries.)

The  Opioid Industry Documents Archive presently holds over 3300 legal documents, much of it coming from litigation in Kentucky and Oklahoma, as well as documents from the Insys investigation, which sold an oral fentanyl spray called Subsys. This archive’s launch coincides with the university hosting over 250 000 documents produced during Insys’ bankruptcy proceedings that resulted from successful lawsuits and criminal prosecutions.

“We don’t really know what’s in these documents yet, but there is a wealth of information,” said Kate Tasker, an associate librarian at UCSF who helps manage the archive. “Our number one goal is to make this information accessible and useful.”

Alexander said the opioid crisis was “an epidemic of catastrophic public health proportions.” He said that placing legal documents in the public domain is a crucial step to ensure that lessons are learned from the crisis.

“The primary goal is to ensure that history never repeats itself,” Alexander said. “And we can’t learn from past mistakes without understanding what those mistakes have been.”

Ideological Divide in the US Undermines Research

The crucial participation of the public in medical research in the United States may be affected by ideological affiliation, thereby undermining medical research, warn researchers from Washington University in St Louis.

The COVID vaccines were developed in an unprecedentedly short time, and this was made possible partly by the participation of over 70 000 volunteers. However, such successes may be in jeopardy if distinct populations cannot be adequately represented, and these include ideologically-based ones.The

distrust of black Americans towards the medical sector, especially research, has been well documented. There are even calls to remove the very concept of race from medical research as many believe it only serves to entrench certain preconceptions. This study, however, is the first to examine the effect of political ideology on willingness to participate in research.

“Our research shows that conservatives are less willing to participate in medical research than are liberals. This difference is due, in part, to ideological differences in trust in science,” said Matthew Gabel, professor of political science in Arts & Sciences.

Such a divide harbours potential consequences where medical research is concerned.

“An ideological divide in such participation could undermine both the execution and quality of medical research,” Prof Gabel said. “Given the uneven geographic distribution of political ideology, our findings raise important issues for recruiting study participants and developing political support for medical research. It could also threaten the generalisability of medical studies since important types of health behaviours, such as smoking, vary with Americans’ political ideology.”

While the problem had been brewing for decades, it was only until ideological disparities towards the medical field were exposed by the COVID pandemic that it gained widespread attention.  For example, a study found that conservative republicans were three times more likely to refuse a vaccine than the more liberal independents or democrats.

Prof Gabel saw this coming from a long way off. He wanted to better understand why some people were more inclined to participate in medical research than others, and joined with John C Morris, MD, the Harvey A. and Dorismae Hacker Friedman Distinguished Professor of Neurology and head of the Alzheimer’s Disease Research Center at the School of Medicine; Catherine M Roe, associate professor of neurology at the School of Medicine; and Stanford University’s Jonathan Goobla.

“The value of research with human subjects depends critically on successful recruitment of a representative group of participants. To do that, we have to know sources of bias in who is recruited and who is likely to accept invitations to participate,” Prof Gabel explained.

The researchers analysed survey data from the July 2014 and September 2015 waves of The American Panel Survey, which asked questions about past and future participation in medical research-related activities. These include a clinical trial for a drug, a long-term observations study, a fundraiser for medical research and blood donation. They also had hypothetical questions about one’s willingness to be an organ donor and willingness to participate in an Alzheimer’s disease study.

They selected 1132 respondents 45 years or older, since only they were old enough to participate in those long-term studies, clinical trials and hypothetical Alzheimer’s Disease study.

Those with conservative ideology are less likely to want to participate in medical research, partly because of their lower levels of trust in science. However this lack of trust only accounted for about a quarter of the effect.

“This means that if we want to reduce or eliminate the ideological difference in participation in medical research, we can do some of that by trying to raise trust in science among conservatives,” said Prof Gabel “But even if we are very effective at doing that, my analysis shows that conservatives will still be less likely to participate for ideological reasons unrelated to trust in science.

“The ideological divide in participation in medical research suggests that clinical trials and other long-term observational studies likely over-represent those with liberal political ideology. This can impact the quality of studies because significant health conditions and behaviours — such as smoking, excessive drinking, diets and mortality rates — differ with political ideology,” Prof Gabel said.

“Given the number and political importance of conservatives, and the relative stability of Americans’ ideological commitments, this divide could signify a significant obstacle for the practice, advance and influence of science in the United States,” Gabel concluded.

‘Re-Emphasise Ethical Foundation of Medicine’, ACP Urges

As healthcare services struggling under COVID are bought out by private equity, the American College of Physicians says that it is important to prioritise duty to the patients.

“Today, changing practice dynamics place greater focus on the business aspects of medicine,” the authors wrote in a position paper in the Annals of Internal Medicine. “Although employment or consolidation within larger organisations may not be problematic per se, physicians, regardless of practice setting, should challenge business concerns that are placed above the best interests of patients.”

Practices are often bought out by private equity firms that invest in them and introduce cost-cutting measures to increase market share, and then sell them on to make a profit. This results in pressures to generate financial returns at the ultimate expense of patient care.

“This desire to sell the practice soon after acquisition can create the incentive to sell off parts of the practice or undertake drastic short-term cost-cutting measures, including staff layoffs, to make a potential sale more attractive,” the authors wrote. “Insurance companies may further narrow their networks or restrict patient access to only their employed physicians.”

One example the authors cited was that of Hahnemann University Hospital in Philadelphia, which was shuttered just a year after being bought out by a for-profit corporation. This left patients without access to medical care, and some 570 medical residents and fellows were left with an uncertain future.

The authors also cautioned that private equity firms could also limit Medicaid and Medicare patients due to more complex needs and lower reimbursement. These are government medical schemes that cover lower-income individuals. Medicaid alone covers 1 in 5 Americans.
Value-based payment, the authors noted, is supposed to promote high-quality care, but there are many concerns such as influencing patient choice and creating affordability barriers to treatment. Extrinsic, financial incentives may compete with the intrinsic desire to help patients. They also noted that referral-based payment is subject to similar ethical concerns. Meanwhile, time spent with patients needs to be valued, they wrote, as this is needed to ensure effective communication, examination and to express compassion.

“The challenges to care and medical practice during and after the COVID-19 pandemic underscore the need to reemphasise the ethical foundation of medicine,” the authors wrote. “Looking anew at the environment in which care is delivered, physicians should lead in ensuring that business relationships explicitly recognise and support the fundamental and timeless commitments of physicians and medicine to patients.”

Op-ed: Facebook Medical ‘Fact Checking’ Has No Room for Debate

Fact-checking is increasingly important in an era of disinformation on social media, especially with the current COVID pandemic, but an article for MedPage Today calls into question the process for Facebook’s medical fact-checking.

After an op-ed in the Wall Street Journal by Marty Makary, MD, MPH, Johns Hopkins professor and editor-in-chief at MedPage Today, was labelled “misleading” by Facebook fact checkers, another op-ed in MedPage Today asks how the social media giant is choosing its medical fact-checkers. 

Mystified by why this would be labelled “misleading” by Facebook, and setting aside the ‘veracity’ of the article, Vinay Prasad, MD, MPH, a haematologist-oncologist and associate professor of medicine at the University of California San Francisco, investigated the website HealthFeedback.org that Facebook uses to fact-check some of its medical articles. 

The process involves two to four reviewers chosen to examine an article. Prior to the COVID pandemic, medical fact checking appears to have been done by academics, but the flood of disinformation has resulted in the change of this process, Dr Prasad noted.  

In one instance, a reviewer for the article was selected because he had already written an article critical of Dr Markary’s op-ed: in other words, he was selected because he had already announced his bias.

The website’s picking and choosing of reviewers “felt like a high school clique”, Dr Prasad wrote. One that allowed them to confirm their previously held ideas about COVID and extinguish differing viewpoints. Labelling the alternative views as misleading “instantly usurps the reader of their ability to make up their own mind. It is antithetical to the spirit of the academy.”

He found that the fact-checkers typically had large Twitter followings, while the typical medical professor seems to have them in the hundreds. This makes sense, Dr Prasad wrote, as leading academics and authorities are likely too busy to be courting large numbers of followers on Twitter.
Other than a “vague explanation” of the feedback process, Dr Prasad could not find any information on how Facebook chooses its reviewers, which of the billions of posts and articles on Facebook to fact-check, whether anyone is paid and how appeals are made.

Man With Motor Neuron Disease Presents His Case for Euthanasia

At a hearing, a man with a deteriorating condition from motor neuron disease (MND), laid out why he wants the right to choose patient-assisted suicide.

Diethelm Harck, 71, is seeking a change in the laws surrounding euthanasia in South Africa. He is presenting his case alongside Dr Suzanne Walter, a palliative care specialist who has multiple myeloma. Both may not live long enough to see the outcome of their application, and have set up trust funds to assist the overturning of laws surround euthanasia and patient-assisted suicide in South Africa.

In his evidence, he said that he loves life “but my biggest fear is that when my love of life reaches the stage of fearing life, I will not be able to die.”

In the hearing via Zoom, Mr Harck said that he used to exercise daily but now takes three hours to complete a simple routine like getting up and making breakfast.Mr Harck said that his deterioration would be progressive; his muscles are weakening eventually he will be unable to breathe as his diaphragm will stop working.

“From what I have seen and witnessed, MND death is not peaceful,” he said. “I have seen a number of colleagues and [support] group members pass away. They had no way to communicate. And they could not breathe easily.”

Mr Harck continued, “We once visited a young girl suffering from MND, who was totally paralysed. She could only speak with the help of an eye gaze machine. When Lynn [Mr Harck’s life partner] asked her what she feared the most, she said not being able to die.”

Their application is being opposed by The Health Professions Council of South Africa and the Ministers of Health, Justice and the National Director of Public Prosecutions. They claimed that palliative care was available to most South Africans and that the right to life must be protected by the ban on euthanasia.

Social Cues Impacts on Human Decision-making in Emergencies

Man at the wheel of a car. Photo by why kei on Unsplash.

A study showed that, when participants in a simulated crash of an autonomous vehicle were told that others had chosen to crash into a wall to save pedestrians, their own willingness to do so went up by two-thirds.

As autonomous vehicles become more commonplace, and the need to program them for safety emerges, a better understanding of how humans react in such situations is needed. Study author Jonathan Gratch, the principal investigator for this project, and a computer scientist at the USC Institute for Creative Technologies, said that current models for humans in life-or-death situations, humans think differently to how they do in reality. There are no moral absolutes, rather ” it is more nuanced”.

Seeking to understand how humans make decisions in life-or-death situations and how to apply them to the programming of autonomous vehicles and robots, researchers presented a modified trolley problem to participants using a modified ‘trolley problem’.

The trolley problem is a classic hypothetical scenario psychologists use to investigate human decision-making. Essentially, it involves the decision to divert a tram to hit one person or to leave it on its track and hit five, and it has a number of variations. In one medical variation of the trolley problem, one person could be killed and their organs harvested to save five terminally ill patients — a choice that is overwhelmingly rejected.  

In three of four simulations presented to them, the participants had to choose whether to tell their autonomous vehicle to hit a wall, risking harm to themselves, or hit five pedestrians. The higher the likelihood of injury to pedestrians, the more likely the participants were to choose hitting the wall and risking self harm. The authors showed that in so doing, people balance the risk of injury to self against the potential of injury to others as a guideline.

In the fourth scenario, a social element was added, where participants were told that their peers had chosen to save the pedestrians. In this case, the proportion of participants electing to save the pedestrian went up from 30% to 50%.

However, Gratch there is a reverse as well: “Technically there are two forces at work. When people realize their peers don’t care, this pulls people down to selfishness. When they realize they care, this pulls them up.”

The researchers showed that using the trolley problem as a basis for decision-making is insufficient, as it fails to capture the complexity of human decision-making. The researchers also concluded that transparency in the programming of autonomous machines was important for the public, as well as human operators assuming control in the event of an emergency.
