Three basic truths about ultraprocessed foods: Junk food, available pretty much everywhere, tastes great. Advertising works. And most of us don’t crave green leafy salads when we’re hungry.

Of those three truths, the one that tends to get more public health attention is advertising. More specifically, advertising junk food to kids. 

Back in the days when cable television was king of all free time, study after study tried to quantify junk- and fast-food advertising to kids and speculated about its impact on childhood obesity rates. But as broadcast television use began fading, advertisers — and, of course, studies about advertising — turned their attention first to gaming and now to social media.

The social media numbers are quite staggering. According to a study published — probably not coincidentally — on Halloween, looking at the 40 top brands of junk- and fast food sold in Canada, those 40 brands alone were mentioned over 16 million times by social media users, reaching an estimated 42 billion total users within a 1-year period. 

And unique to the challenge of junk- and fast-food advertising on social media is that it also includes “earned” advertising, the kind not paid for by manufacturers but rather the kind where friends, family, and influencers post about junk food. Occasionally, though, these lines are blurred by initiatives from fast-food manufacturers explicitly encouraging social sharing. Consequently, even were there a desire, there isn’t likely to be a regulatory mechanism to markedly reduce it. 

For years, here in North America, excepting Quebec, the desire has been mainly to just talk about how concerned we are about junk-food advertising to kids. Elsewhere, however, some countries tried to do more, including both Mexico and Chile, which put kid-targeted TV food advertising bans in place in 2014 and 2016, respectively. 

Did they work? It depends on what outcome you’re considering. If the question is, did they work in regard to obesity? — which is how everyone tends to frame the question — by themselves, probably not. No one sandbag stops a flood, and though junk-food advertising is certainly a sandbag, we’re still facing a torrential downpour of obesity contributors. No doubt they did work to reduce kids’ exposure to junk-food advertising on television, but what remains to be seen is whether there is a means to now tackle social media’s generous servings of the same. Moreover, the obesity lens is the wrong one. Ultraprocessed food consumption isn’t good for anyone, regardless of weight, and its reduced marketing and consumption is a worthy goal of its own.

But Chile and Mexico are filling more than single sandbags, as both countries have rolled out a suite of interventions they are hoping will help improve nutrition: from front-of–package labeling reforms and warnings, to the banning of advertising geared specifically to appeal to children (like sugary cereal cartoon mascots), to implementing sugar-sweetened-beverage taxes, to having blanket overall bans on food advertising during the daytime.

Mexico is even taking first steps to start addressing junk food’s ubiquity by banning its sale in schools altogether. Schools found to be selling common Mexican junk food fare, such as sugary fruit drinks; chips; artificial pork rinds; and soy-encased, salty peanuts with chili, will see their administrators facing heavy fines. 

Because therein lies the biggest rub. Going back to those three simple truths, junk food is hyperpalatable and consequently tends to be what we crave when we’re hungry. So even if we miraculously one day do more than just talk about advertising reforms, and especially given that we won’t be able to do anything about social media’s earned product placements, junk food’s ubiquitous availability within arms’ reach or on our Uber Eats apps will see us be likely to continue its excessive consumption. 

That’s not to say we shouldn’t emulate Mexico and Chile’s initiatives, nor that they shouldn’t continue to build upon them, but one thing is certain: Human nature and inconvenient truths around food are incredibly powerful forces that we haven’t yet figured out how to tame.

In a new statement, the American Diabetes Association (ADA) has advised against the use of compounded glucagon-like peptide 1 receptor agonist (GLP-1 RA) and dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA medication classes.

The ADA recommends GLP-1 RA and GIP/GLP-1 RA medications approved by the Food and Drug Administration (FDA) for the treatment of type 2 diabetes, cardiovascular and kidney disease risk reduction, and weight management. The new ADA statement pertains to the unapproved, unregulated versions that have emerged as the demand for these medications for weight loss increases. These are often marketed directly to consumers.

“Compounded GLP-1 RA and dual GIP/GLP-1 RA products have been associated with clinically important dosing errors and adverse events. More concerning to individuals’ safety are counterfeit products that have made their way into the US drug supply chain and those advertised online and by unregulated sources,” the ADA said in the statement, published online on December 2, 2024, in Diabetes Care.

The statement, authored by Joshua J. Neumiller, PharmD, CDCES, of the Department of Pharmacotherapy, Washington State University, Spokane, and colleagues, states the following:

• Non–FDA-approved compounded incretin products are not recommended for use due to uncertainty about their content and resulting concerns about safety, quality, and effectiveness.
• If an incretin medication is unavailable (eg, in shortage), switching to a different FDA-approved medication is recommended as clinically appropriate to achieve and maintain individualized glucose-lowering, weight management, and/or cardiovascular and kidney risk reduction goals.
• Upon resolution of incretin product unavailability, reassess the appropriateness of resuming the original FDA-approved incretin medication.

The document points out that compounded products are not identical to the FDA-approved versions, may be distributed in nonstandard dosing devices, and may not provide sufficient user instructions.

However, “the ADA also recognizes that individuals and clinicians may still elect to use or recommend compounded products for financial or other reasons,” and therefore offers additional advice for the public, including the following:

• Discuss product use with their usual healthcare providers.
• Only use products that include dosing guidance.
• Verify that the compounding pharmacy is registered with FDA.

In addition, report any adverse events or medication errors to the FDA’s Medwatch.

VANCOUVER, BRITISH COLUMBIA — Canadian women aged 40-49 years at no or moderate risk for breast cancer who participated in organized mammography screening programs had a significantly greater breast cancer 10-year net survival than that of similar women who did not participate in such programs, according to data presented here at the Family Medicine Forum 2024. 

The data call into question draft guidelines from the Canadian Task Force on Preventive Health Care, which suggest not systematically screening women in this age group with mammography.

 

Overdiagnosis Challenged

Given that some jurisdictions in Canada have organized screening programs and some do not, there was an opportunity to compare breast cancer 10-year net survival of women who lived in jurisdictions with and without such programs, explained family physician Anna N. Wilkinson, MD, Ottawa regional cancer primary care lead and associate professor at the University of Ottawa in Ontario, Canada.

“The question was [whether] we could use big cancer data to figure out what’s going on,” she told this news organization. 

To investigate, Wilkinson and co-investigators reviewed data from the Canadian Cancer Registry linked to mortality information and assessed outcomes for women aged 40-49 and 50-59 years diagnosed with breast cancer from 2002 to 2007. They compared 10-year net survival estimates in jurisdictions with organized screening programs for those aged 40-49 years with the jurisdictions without them. 

“Net survival is important because it’s a survival measure that looks at only the cancer in question,” Wilkinson explained.

Investigators determined breast cancer to be the primary cause of 10-year mortality in women aged 40-49 years diagnosed with the disease (90.7% of deaths). 

Furthermore, the 10-year net survival in jurisdictions that screened these women (84.8%) was 1.9 percentage points higher than for jurisdictions that did not (82.9%). 

The difference in 10-year net survival favoring jurisdictions that offered screening was significant for women aged 45-49 years (2.6 percentage points) but not for those aged 40-44 years (0.9 percentage points).

Given that 90% of the deaths in women in their 40s who had a breast cancer diagnosis were due to breast cancer, Wilkinson challenged the concept of women in their 40s being overdiagnosed with breast cancer, meaning that the cancers detected were indolent and did not require treatment nor result in death.

Earlier detection would generally mean finding disease at an earlier stage and the need for less invasive treatment, she noted. “And one of the biggest benefits [of screening women in their 40s] is that you have diagnosis at earlier stage disease, which means fewer intensive therapies, less time off work, less long-term morbidity, and less cost to our healthcare system.”

 

Modeling Shows Little Screening Benefit

The task force’s draft guidelines, released earlier this year, were based on evidence from 165 studies including randomized, controlled trials, observational studies, time-trend studies and modeling. They suggest not systematically screening women 40-49 with mammography who are not high risk.

Family physician Guylène Thériault, MD, chair of the task force and its breast cancer working group, and director of the Pedagogy Center at the Outaouais Campus, McGill University, Montreal, Quebec, Canada, explained that to come to that conclusion, the task force had assessed the impact of organized screening for women in Canada aged 40-49 years and calculated the impact of mammography for every 1000 women over 10 years.

The model suggested that screening would yield 368 false positives, leading to 55 biopsies, and then to a breast cancer diagnosis in 19 women. Of those 19, the task force estimated 17 or 18 would not die of breast cancer over 10 years, two would be treated for breast cancer that would not have caused problems, ie, overdiagnosis, and one to two would die of breast cancer.

Without screening, on the other hand, the model suggested that 983 of 1000 women aged 40-49 years would not be diagnosed with breast cancer, and 17 would be, 15 of whom would not die from breast cancer over 10 years (no overdiagnosis, no deaths prevented) and two would die.

It is important that family physicians provide their patients with this information to assist in shared decision making about screening, Thériault said.

Wilkinson concluded that screening programs that included women in their 40s were associated with a significantly higher breast cancer 10-year survival, without an increased rate of diagnosis. She suggested that the study findings can inform the screening guidelines for women aged 40-49 years. 

The study was supported by the University of Ottawa’s department of family medicine.

The emergence of vorasidenib, the first targeted therapy for certain gliomas with IDH mutations, has ignited a wave of excitement in both patient and physician spaces.

After years with limited treatment options, experts hailed vorasidenib “a promising breakthrough,” “a paradigm shift,” a “new hope,” and “probably the most important advance in the treatment of low-grade gliomas in the last decade.”

Promising results from vorasidenib’s pivotal INDIGO trial fueled petitions and patient advocacy circles to push for the drug’s approval. And, in August 2024, the Food and Drug Administration (FDA) approved vorasidenib for grade 2 astrocytomas or oligodendrogliomas with an IDH1 or IDH2 mutation.

But following the approval, some experts expressed concerns and doubts about the drug and the INDIGO trial, bringing a host of unanswered questions into sharper focus.

In an editorial, Stanislav Lazarev, MD, and Kunal K. Sindhu, MD, both radiation oncologists from Icahn School of Medicine at Mount Sinai, New York City, suggest that the FDA approval “might be premature given the high cost of this drug and lack of clear benefit over standard treatments.”

Another recent critique also pointed to the lack of clear evidence that vorasidenib is superior to the prevailing standard of care, despite the drug’s high cost. These authors noted that “patients want to live longer, and if not, at least live better,” but “based on the INDIGO study, it is impossible to say whether vorasidenib can provide either.”

Vorasidenib is now one of the most expensive cancer therapies, with an annual cost of nearly $500,000, but the INDIGO trial did not explore whether the drug led to improved overall survival or better quality of life. Among the trial’s design flaws, experts called out the use of progression-free survival as the primary outcome, instead of overall survival, and the use of an inappropriate comparator group.

INDIGO was a phase 3 trial that included 331 adult patients (median age, 40.5 years) with grade-2 IDH-mutant recurrent or residual glioma after surgery. To be eligible, patients had to be followed for at least 1 year, and up to 5 years, post surgery and had to be considered appropriate candidates for a watch-and-wait approach.

Participants were randomly assigned to receive either 40 mg of vorasidenib or a matching placebo orally, once daily, in continuous 28-day cycles until imaging-confirmed tumor disease progression or unacceptable toxicity, at which point crossover to vorasidenib from placebo was permitted. Over one third (n = 58) of patients in the placebo group crossed over and 90% of them (n = 52) received vorasidenib.

Median progression-free survival was significantly better in the vorasidenib group at 27.7 months vs 11.1 months in the placebo group (hazard ratio [HR], 0.39).

A key secondary endpoint — time to next intervention — was also significant; the likelihood of being alive and not receiving further treatment at 18 months was 85.6% in the vorasidenib group and 47.4% in the placebo group (HR, 0.26). This finding indicates that most patients receiving vorasidenib could delay chemoradiation for 18 months or longer.

Despite these impressive outcomes, some experts noted that using progression-free survival as the primary endpoint was a major flaw of the INDIGO trial because, currently, there is no evidence that progression-free survival is a reliable surrogate endpoint for overall survival in this setting.

The high rate of crossover to vorasidenib is another issue because it may limit a longer-term analysis of overall survival. If, for instance, overall survival is the same between the groups, it could signal that the drug is effective in both groups or, alternatively, that the drug has no effect on survival in either group.

“That is a legitimate concern,” Seema Nagpal, MD, a neuro-oncologist at Stanford University in California, and a site principal investigator for the INDIGO trial, said in an interview. “We don’t know that this drug changes overall survival, and I think we’re not going to get a super clean answer on that.”

Another major issue centers on the standard of care assigned to control patients in the INDIGO trial.

In the trial, vorasidenib was compared with placebo — an appropriate standard-of-care comparison for patients with low-risk gliomas. These patients often initially undergo watch-and-wait to delay chemoradiation. But Lazarev and Sindhu argue that the patients in INDIGO were really high risk, which means the control group should have received the standard of care for these patients: Chemoradiation following surgery.

This question about the appropriate standard of care stems from ongoing uncertainty about the distinction between high- and low-risk gliomas.

The classification for gliomas falls into either low risk or high risk for early disease progression. The RTOG 9802 criteria, often used for glioma risk stratification, defines low-risk patients as those younger than 40 years with gross total resection and high-risk patients as those aged 40 years or older with any extent of resection or those younger than 40 years with subtotal or biopsy resection.

But an evolving understanding of genetic anomalies that affect prognoses in this tumor type has muddied the current high- and low-risk distinctions.

“People haven’t totally figured out what high and low risk means,” Nagpal acknowledged.

This uncertainty has spilled over into the INDIGO trial.

While the trial excluded patients who had any features indicating high risk, such as brain stem involvement or neurocognitive deficits, the researchers also did not explicitly define patients as low risk. However, the inclusion criteria specified that patients had to be observed for at least 1 year after surgery and be considered appropriate for a watch-and-wait protocol, which does suggest patients were considered low risk, said Nagpal.

Still, some experts argue that the patients in INDIGO were not low risk.

Patients had residual or recurrent disease so “wouldn’t be classified as low risk,” said Sindhu in an interview. The standard of care for these patients is chemoradiation, Lazarev added.

“The definition of a phase 3 clinical trial is that you compare the novel intervention to the standard of care,” said Lazarev. “Level 1 evidence clearly shows that omitting chemoradiation leads to worse outcomes, with patients literally dying sooner. For the investigators to knowingly exclude this proven treatment raises serious ethical and methodological questions about the study’s design.” 

In a recent opinion piece, Nagpal agreed that most patients selected for INDIGO would not have been considered low risk by many providers. All patients selected for INDIGO had postoperative residual/recurrent disease and many were older than 40 years.

But, Nagpal explained, the risk stratification of the INDIGO patients was still lower than what is commonly considered high risk. The patients had all been observed for a year or more already, “so by definition, the clinician treating them already decided they were not high risk,” she said.

In another recent opinion piece, oncologists suggested that, because patients in the INDIGO trial do not squarely fall into either category, instead representing a “grey area,” it’s time to create a new risk category.

“Perhaps the time has come to abandon the old binary risk stratification (“low risk” vs “high risk”), which still contains arbitrary elements (such as the age cutoff), proving impractical in real-world clinical decision-making, and to adopt a new one, also taking into account many emerging prognostic biomarkers,” the authors wrote.

Despite the uncertainty surrounding risk categories, the INDIGO authors justified their study design.

A watch-and-wait period for patients in the trial, which “represents the earliest clinical phase in tumorigenesis of IDH-mutant WHO grade 2 glioma,” is “an opportunity to detect a clear signal of antitumor activity for new therapies in placebo-controlled trials” and “postpone the use of radiation therapy and chemotherapy,” the authors explained.

Lazarev, however, questioned the premise that chemoradiation should be delayed.

Oncologists’ desire to delay chemoradiation for their patients reflects “a limited understanding of modern irradiation therapy,” Lazarev said. “Modern technology has improved dramatically. We’re more precise, our understanding about late side effects is better. So, the big picture is that the absolute risk of late neurocognitive affects that actually will affect patients’ quality of life, their ability to work, go to school, succeed on a personal or professional level is exceedingly low.”

Nagpal strongly disagreed.

“Please come to my clinic and ask an actual patient,” said Nagpal. “Once a radiation oncologist has irradiated the patient, they almost never seen them again. People who are on the medical side, who follow these patients from beginning to end, recognize that delaying radiation is a huge deal.”

Although vorasidenib isn’t a cure, Nagpal said, it is a less toxic way to delay radiation “because that is a real and disabling thing” for patients and is why neuro-oncologists are excited about alternative treatment options.

Another issue surrounding the vorasidenib approval lies in the FDA’s vague prescribing information. The prescribing information does not specify that patients should be followed for at least 1 year post surgery or that patients need to be lower risk. Prescribing physicians may, therefore, think vorasidenib is appropriate for any patient with a grade-2 IDH mutant glioma at any time and defer or not offer chemoradiation to high-risk patients.

Amid lingering questions about the INDIGO trial design and ongoing uncertainties about how to define and treat this patient population, experts remain divided on whether vorasidenib is worth it.

“If vorasidenib is truly transformative, it should be feasible to demonstrate its superiority over chemoradiotherapy,” Lazarev and Sindhu wrote. “For a drug with such a staggering price tag, an imperative should be placed on the investigators and manufacturer to provide clear evidence of efficacy, whether in terms of improved [overall survival] or quality of life, before vorasidenib is recommended for the treatment of IDH-mutant low-grade gliomas.”

The INDIGO trial was supported by Servier, the manufacturer of vorasidenib. Many of the study authors reported employment or support from the company. Nagpal reported consulting fees from Servier and AnHeart Therapeutics. Lazarev and Sindhu reported no relevant financial relationships.

The emergence of vorasidenib, the first targeted therapy for certain gliomas with IDH mutations, has ignited a wave of excitement in both patient and physician spaces.

After years with limited treatment options, experts hailed vorasidenib “a promising breakthrough,” “a paradigm shift,” a “new hope,” and “probably the most important advance in the treatment of low-grade gliomas in the last decade.”

Promising results from vorasidenib’s pivotal INDIGO trial fueled petitions and patient advocacy circles to push for the drug’s approval. And, in August 2024, the Food and Drug Administration (FDA) approved vorasidenib for grade 2 astrocytomas or oligodendrogliomas with an IDH1 or IDH2 mutation.

But following the approval, some experts expressed concerns and doubts about the drug and the INDIGO trial, bringing a host of unanswered questions into sharper focus.

US regulators’ use of a speedy clearance pathway for a new frontline indication for asciminib for chronic myeloid leukemia (CML) has raised questions due to the number of medications already available for this condition.

In October, the US Food and Drug Administration (FDA) granted accelerated approval to asciminib (Scemblix, Novartis AG) for adult patients with newly diagnosed Philadelphia chromosome–positive CML in chronic phase.

Asciminib is one of the six tyrosine kinase inhibitor (TKI) drugs used for CML, a class that began with the introduction of imatinib (Gleevec) in 2001. By 2016, researchers reported that TKIs had helped make life expectancy in patients with CML approach that of the general population. Physicians and patients now have several options of second-generation TKI drugs that also can be used in newly diagnosed patients, along with the option to begin with the more affordable option of imatinib.

The FDA in 1992 instituted the accelerated approval pathway to try to speed market drugs for serious conditions that fill unmet medical needs.

The agency and companies essentially make bets on promising study results, often using surrogate markers, to allow sales of medicines while waiting for evidence from confirmatory studies. For example, the FDA in August used the accelerated approval process to clear the first T-cell receptor gene therapy for certain advanced forms of sarcoma, a form of cancer with limited treatment options.

The next accelerated approval of a cancer drug was the indication for asciminib as a frontline therapy. The FDA also used accelerated approval for the initial clearance of asciminib in 2021 for use in CML previously treated with two or more TKIs. By 2022, Novartis presented sufficient evidence of the drug’s merit to win full approval for the drug in this use.

The timeline is longer for the expected confirmatory research for asciminib as a frontline therapy, with a 2028 deadline set for this work. The data presented to date on asciminib have not persuaded some oncologists on the need for the speedy approval of frontline use.

“This boils down to a drug that looks as if it’s just as good as other second-generation TKIs,” Mikkael A. Sekeres, MD, MS, chief of the Division of Hematology at the Sylvester Comprehensive Cancer Center, University of Miami Health System, Miami. “I don’t know how they could use the accelerated approval mechanism to get this through.”

Sekeres, a former chair of the Oncologic Drugs Advisory Committee, explored concerns and challenges involved with the use of the accelerated approval process in his 2022 book, Drugs and the FDA: Safety, Efficacy, and the Public’s Trust.

“The intent of the accelerated approval mechanism is that you’re bringing a new therapy to treat a serious disease in a way that others haven’t previously, where there aren’t existing options,” Sekeres said.

This is a markedly different situation that exists for CML, where medicines have improved dramatically in the 21st century, unlike many other forms of cancer treated by hematologists.

“As someone who specializes in treating people with leukemia, I’d be happy every clinic day of my life if all of my patients came in with chronic phase, chronic myeloid leukemia,” instead of other cancers lacking these robust treatment options, he said.

With CML, physicians select among TKIs considering side effects and other health conditions patients have, including weighing the impact of financial toxicity in some cases, he said.

“If I have a patient with lower risk chronic phase, chronic myeloid leukemia, I’m treating them with imatinib,” Sekeres said.

 

Questions About Surrogate Endpoints

Sekeres is not alone in questioning the use of the speedier FDA pathway for a new indication for a TKI in CML.

“Where is the ‘unmet need’ justifying an accelerated approval in this setting?” Timothée Olivier, MD, who is affiliated with both the Hôpitaux universitaires de Genève and the VK Prasad Laboratory funded by Vinay Prasad, MD, MPH, wrote in a November 3 post on X.

Olivier, Prasad, and coauthors in a September correspondence to the American Journal of Hematology raised questions about the study design for a key asciminib study, ASC4FIRST. They noted what they consider a weakness with the endpoints used.

“Molecular milestones like the 48-week MMR [major molecular response] are often used in clinical trials due to their convenience and shorter timeline for assessment,” they wrote. “However, these milestones are not definitive indicators of long-term survival or overall clinical benefit.”

There has been rising concern in recent years about the evidence gap between initial accelerated approvals and the completion of studies that show whether these promising therapies actually help patients live longer or better. Researchers including Bishal Gyawali, MD, PhD, a Medscape Medical News contributor, also have questioned the degree of reliance on surrogate endpoints in accelerated approvals.

In response, the FDA’s Cancer Division and the US Congress have taken steps to try to force drugmakers to more quickly answer the key question in accelerated approvals: Does this medicine produce the expected benefits? For example, the FDA in March appears to have turned down a bid for accelerated approval of a lymphoma drug due to concerns about the timing of completion of confirmatory research.

The use of accelerated approval will continue to be a balancing act, due in part to demand for newer agents, Ravi Bhatia, MD, of the O’Neal Comprehensive Cancer Center at The University of Alabama at Birmingham, told this news organization.

“Accelerated approval of agents for up-front treatment of CML does not appear well justified, given the high degree of efficacy of existing agents,” said Bhatia, vice chair of the National Comprehensive Cancer Network’s Clinical Practice Guidelines in Oncology Panel for Chronic Myeloid Leukemia.

“On the other hand, there is greater urgency for developing agents for patients who have failed existing agents and patients with advanced phase disease, and the use of accelerated approval may be justified in this setting,” Bhatia said.

In an interview with this news organization, Richard A. Larson, MD, a professor in the Department of Hematology/Oncology at The University of Chicago, who is an ASC4FIRST investigator, noted the 96-week follow-up data from the trial will be presented at the annual meeting of the American Society of Hematology in December in San Diego.

Larson said data from this trial will show continued benefit with the frontline use of asciminib. Larson also is an author of a New England Journal of Medicine article in May about the ASC4FIRST trial.

“The data speak for themselves, that asciminib is at least as effective or more so and at least as well tolerated as what’s already on the market,” Larson said. “So their argument, at the end of the day, really boils down to the cost of a new drug and whether we need a new drug.”

From the point of view of patients with cancer, the answer to that is clear, he said.

“If you talk to cancer patients, they’d like to see new drugs become available as quickly as possible. And I think that was the original rationale for the accelerated approval pathway, that a drug that has been shown to be safe and effective in a prospective clinical trial could get accelerated approval based on a surrogate endpoint.”

The remarkable success seen in developing TKI drugs for CML creates difficulties in testing later entrants in this class due to their prolonged survival, Larson said.

“If you look on a population basis, the overall survival of newly diagnosed CML patients with all of these therapeutic options available to them now approximate that of the non-CML population.”

“For most anticancer drugs, the FDA would like to see an overall survival benefit, but patients with newly diagnosed CML are surviving 20 or 30 years, and they’re not dying at an accelerated rate the way they were. So it’d be impractical to require a clinical trial to show a survival benefit, a randomized trial.”

“That’s where the use of a surrogate endpoint, which is the major molecular response at 1 year, has been so valuable, gets the drugs approved, gets them into patients far earlier than if there was a survival end point requirement,” he said.

Larson reported ties with AbbVie, Amgen, Astellas, Celgene, Cellectis, Curis, CVS Caremark, Daiichi Sankyo, ImmunoGen, Jazz, MorphoSys, Rigel, Servier, Forty Seven/Gilead, Novartis, and Rafael Pharmaceuticals. Sekeres disclosed relationships with BMS, Kurome, and Novartis Advisory Boards. Bhatia reported no relevant disclosures.

US regulators’ use of a speedy clearance pathway for a new frontline indication for asciminib for chronic myeloid leukemia (CML) has raised questions due to the number of medications already available for this condition.

In October, the US Food and Drug Administration (FDA) granted accelerated approval to asciminib (Scemblix, Novartis AG) for adult patients with newly diagnosed Philadelphia chromosome–positive CML in chronic phase.

Asciminib is one of the six tyrosine kinase inhibitor (TKI) drugs used for CML, a class that began with the introduction of imatinib (Gleevec) in 2001. By 2016, researchers reported that TKIs had helped make life expectancy in patients with CML approach that of the general population. Physicians and patients now have several options of second-generation TKI drugs that also can be used in newly diagnosed patients, along with the option to begin with the more affordable option of imatinib.

The FDA in 1992 instituted the accelerated approval pathway to try to speed market drugs for serious conditions that fill unmet medical needs.

The agency and companies essentially make bets on promising study results, often using surrogate markers, to allow sales of medicines while waiting for evidence from confirmatory studies. For example, the FDA in August used the accelerated approval process to clear the first T-cell receptor gene therapy for certain advanced forms of sarcoma, a form of cancer with limited treatment options.

The next accelerated approval of a cancer drug was the indication for asciminib as a frontline therapy. The FDA also used accelerated approval for the initial clearance of asciminib in 2021 for use in CML previously treated with two or more TKIs. By 2022, Novartis presented sufficient evidence of the drug’s merit to win full approval for the drug in this use.

The timeline is longer for the expected confirmatory research for asciminib as a frontline therapy, with a 2028 deadline set for this work. The data presented to date on asciminib have not persuaded some oncologists on the need for the speedy approval of frontline use.

“This boils down to a drug that looks as if it’s just as good as other second-generation TKIs,” Mikkael A. Sekeres, MD, MS, chief of the Division of Hematology at the Sylvester Comprehensive Cancer Center, University of Miami Health System, Miami. “I don’t know how they could use the accelerated approval mechanism to get this through.”

Sekeres, a former chair of the Oncologic Drugs Advisory Committee, explored concerns and challenges involved with the use of the accelerated approval process in his 2022 book, Drugs and the FDA: Safety, Efficacy, and the Public’s Trust.

“The intent of the accelerated approval mechanism is that you’re bringing a new therapy to treat a serious disease in a way that others haven’t previously, where there aren’t existing options,” Sekeres said.

This is a markedly different situation that exists for CML, where medicines have improved dramatically in the 21st century, unlike many other forms of cancer treated by hematologists.

“As someone who specializes in treating people with leukemia, I’d be happy every clinic day of my life if all of my patients came in with chronic phase, chronic myeloid leukemia,” instead of other cancers lacking these robust treatment options, he said.

With CML, physicians select among TKIs considering side effects and other health conditions patients have, including weighing the impact of financial toxicity in some cases, he said.

“If I have a patient with lower risk chronic phase, chronic myeloid leukemia, I’m treating them with imatinib,” Sekeres said.

 

Questions About Surrogate Endpoints

Sekeres is not alone in questioning the use of the speedier FDA pathway for a new indication for a TKI in CML.

“Where is the ‘unmet need’ justifying an accelerated approval in this setting?” Timothée Olivier, MD, who is affiliated with both the Hôpitaux universitaires de Genève and the VK Prasad Laboratory funded by Vinay Prasad, MD, MPH, wrote in a November 3 post on X.

Olivier, Prasad, and coauthors in a September correspondence to the American Journal of Hematology raised questions about the study design for a key asciminib study, ASC4FIRST. They noted what they consider a weakness with the endpoints used.

“Molecular milestones like the 48-week MMR [major molecular response] are often used in clinical trials due to their convenience and shorter timeline for assessment,” they wrote. “However, these milestones are not definitive indicators of long-term survival or overall clinical benefit.”

There has been rising concern in recent years about the evidence gap between initial accelerated approvals and the completion of studies that show whether these promising therapies actually help patients live longer or better. Researchers including Bishal Gyawali, MD, PhD, a Medscape Medical News contributor, also have questioned the degree of reliance on surrogate endpoints in accelerated approvals.

In response, the FDA’s Cancer Division and the US Congress have taken steps to try to force drugmakers to more quickly answer the key question in accelerated approvals: Does this medicine produce the expected benefits? For example, the FDA in March appears to have turned down a bid for accelerated approval of a lymphoma drug due to concerns about the timing of completion of confirmatory research.

The use of accelerated approval will continue to be a balancing act, due in part to demand for newer agents, Ravi Bhatia, MD, of the O’Neal Comprehensive Cancer Center at The University of Alabama at Birmingham, told this news organization.

Rose Gerber was 39, mother to a third grader and a kindergartener, when the diagnosis came: Advanced HER2-positive breast cancer.

“On one of my first or second appointments, I took in a little picture of Alexander and Isabella,” Gerber said. Gerber showed her oncologist the picture and told her: “I’ll do anything. I just want to be there for them.”

That was 21 years ago. Today, her current cancer status is “no evidence of disease.”

Over the past 2 decades, Gerber has gotten to be there for her children. Her youngest is now a television producer and her oldest, a CPA.

In that time, Gerber has had one constant: Her oncologist, Kandhasamy Jagathambal, MD, or Dr. Jaga, as she’s often called. 

“I’ve seen multiple physicians over my 21 years, but my oncologist has always been the focal point, guiding me in the right direction,” Gerber said in an interview.

Over the years, Jaga guided Gerber through a range of treatment decisions, including a Herceptin clinical trial that the mom of two views as lifesaving. Jaga often took on the role of both doctor and therapist, even providing comfort in the smaller moments when Gerber would fret about her weight gain.

The oncologist-patient “bond is very, very, very special,” said Gerber, who now works as director of patient advocacy and education at the Community Oncology Alliance.

Gerber isn’t alone in calling out the depth of the oncologist-patient bond.

Over years, sometimes decades, patients and oncologists can experience a whole world together: The treatment successes, relapses, uncertainties, and tough calls. As a result, a deep therapeutic alliance often develops. And with each new hurdle or decision, that collaborative, human connection between doctor and patient continues to form new layers.

“It’s like a shared bonding experience over trauma, like strangers trapped on a subway and then we get out, and we’re now on the other side, celebrating together,” said Saad Khan, MD, an associate professor of medicine (oncology) at Stanford University in California.

 

Connecting Through Stress

Although studies exploring the oncologist-patient bond are limited, some research suggests that a strong therapeutic alliance between patients and oncologists not only provides a foundation for quality care but can also help improve patients’ quality of life, protect against suicidal ideation, and increase treatment adherence.

Because of how stressful and frightening a cancer diagnosis can be, creating “a trusting, uninterrupted, almost sacred environment for them” is paramount for Khan. “I have no doubt that the most important part of their treatment is that they find an oncologist in whom they have total confidence,” Khan wrote in a blog.

The stress that patients with cancer experience is well documented, but oncologists take on a lot themselves and can also experience intense stress (.

“I consider my patient’s battles to be my battles,” Khan wrote.

The stress can start with the daily schedule. Oncologists often have a high volume of patients and tend to spend more time with each individual than most.

According to a 2023 survey, oncologists see about 68 patients a week, on average, but some oncologists, like Khan, have many more. Khan typically sees 20-30 patients a day and continues to care for many over years.

The survey also found that oncologists tend to spend a lot of time with their patients. Compared with other physicians, oncologists are two times more likely to spend at least 25 minutes with each patient.

With this kind of patient volume and time, Khan said, “you’re going to be exhausted.”

What can compound the exhaustion are the occasions oncologists need to deliver bad news — this treatment isn’t working, your cancer has come roaring back and, perhaps the hardest, we have no therapeutic options left. The end-of-life conversations, in particular, can be heartbreaking, especially when a patient is young and not ready to stop trying.

“It can be hard for doctors to discuss the end of life,” Don Dizon, MD, director of the Pelvic Malignancies Program at Lifespan Cancer Institute and director of Medical Oncology at Rhode Island Hospital, Providence, wrote in a column in 2023. Instead, it can be tempting and is often easier to focus on the next treatment, “instilling hope that there’s more that can be done,” even if doing more will only do harm.

In the face of these challenging decisions, growing a personal connection with patients over time can help keep oncologists going.

“We’re not just chemotherapy salesmen,” Khan said in an interview. “We get to know their social support network, who’s going to be driving them [to and from appointments], where they go on vacation, their cat’s name, who their neighbors are.”

 

A ‘Special Relationship’

Ralph V. Boccia, MD, is often asked what he does.

The next question that often comes — “Why do I do what I do?” — is Boccia’s favorite.

“Someone needs to take these patients through their journey,” Boccia, the founder of The Center for Cancer and Blood Disorders, Bethesda, Maryland, typically responds. He also often notes that “it is a special relationship you develop with the patient and their families.”

Boccia thinks about one long-term patient who captures this bond.

Joan Pinson, 70, was diagnosed with multiple myeloma about 25 years ago, when patients’ average survival was about 4 years.

Over a quarter century, Pinson has pivoted to different treatments, amid multiple relapses and remissions. Throughout most of this cancer journey, Boccia has been her primary oncologist, performing a stem cell transplant in 2000 and steering her to six clinical trials.

Her last relapse was 2 years ago, and since then she has been doing well on oral chemotherapy.

“Every time I relapsed, by the next appointment, he’d say, ‘here is what we are going to do,’ ” Pinson recalled. “I never worried, I never panicked. I knew he would take care of me.”

Over the years, Pinson and Boccia have shared many personal moments, sometimes by accident. One special moment happened early on in Pinson’s cancer journey. During an appointment, Boccia had “one ear to the phone” as his wife was about to deliver their first baby, Pinson recalled.

Later, Pinson met that child as a young man working in Boccia’s lab. She has also met Boccia’s wife, a nurse, when she filled in one day in the chemotherapy room.

Boccia now also treats Pinson’s husband who has prostate cancer, and he ruled out cancer when Pinson’s son, now in his 40s, had some worrisome symptoms.

More than 2 decades ago, Pinson told Boccia her goal was to see her youngest child graduate from high school. Now, six grandsons later, she has lived far beyond that goal.

“He has kept me alive,” said Pinson.

 

The Dying Patient

Harsha Vyas, MD, FACP, remembers the first encounter his office had with a 29-year-old woman referred with a diagnosis of stage IV breast cancer.

After just 15 minutes in the waiting room, the woman announced she was leaving. Although office staff assured the woman that she was next, the patient walked out.

Several months later, Vyas was called for an inpatient consult. It was the same woman.

Her lungs were full of fluid, and she was struggling to breathe, said Vyas, president and CEO of the Cancer Center of Middle Georgia, Dublin, and assistant professor at Augusta University in Georgia.

The woman, a single mother, told Vyas about her three young kids at home and asked him, “Doc, do something, please help me,” he recalled.

“Absolutely,” Vyas told her. But he had to be brutally honest about her prognosis and firm that she needed to follow his instructions. “You have a breast cancer I cannot cure,” he said. “All I can do is control the disease.”

From that first day, until the day she died, she came to every appointment and followed the treatment plan Vyas laid out.

For about 2 years, she responded well to treatment. And as the time passed and the trust grew, she began to open up to him. She showed him pictures. She talked about her children and being a mother.

“I’ve got to get my kids in a better place. I’m going to be there for them,” he recalled her saying.

Vyas admired her resourcefulness. She held down a part-time job, working retail and at a local restaurant. She figured out childcare so she could get to her chemotherapy appointments every 3 weeks and manage the copays.

Several years later, when she knew she was approaching the end of her life, she asked Vyas a question that hit hard.

“Doc, I don’t want to die and my kids find me dead. What can we do about it?”

Vyas, who has three daughters, imagined how traumatic this would be for a child. She and Vyas made the shared decision to cease treatment and begin home hospice. When the end was approaching, a hospice worker took over, waiting for bodily functions to cease.

When news of a death comes, “I say a little prayer, it’s almost like a send-off for that soul. That helps me absorb the news ... and let it go.”

But when the bond grows strong over time, as with his patient with breast cancer, Vyas said, “a piece of her is still with me.”

Khan had no relevant disclosures. Boccia and Vyas had no disclosures.

Over the years, Pinson and Boccia have shared many personal moments, sometimes by accident. One special moment happened early on in Pinson’s cancer journey. During an appointment, Boccia had “one ear to the phone” as his wife was about to deliver their first baby, Pinson recalled.

Later, Pinson met that child as a young man working in Boccia’s lab. She has also met Boccia’s wife, a nurse, when she filled in one day in the chemotherapy room.

Boccia now also treats Pinson’s husband who has prostate cancer, and he ruled out cancer when Pinson’s son, now in his 40s, had some worrisome symptoms.

More than 2 decades ago, Pinson told Boccia her goal was to see her youngest child graduate from high school. Now, six grandsons later, she has lived far beyond that goal.

“He has kept me alive,” said Pinson.

 

The Dying Patient

Harsha Vyas, MD, FACP, remembers the first encounter his office had with a 29-year-old woman referred with a diagnosis of stage IV breast cancer.

After just 15 minutes in the waiting room, the woman announced she was leaving. Although office staff assured the woman that she was next, the patient walked out.

Several months later, Vyas was called for an inpatient consult. It was the same woman.

Her lungs were full of fluid, and she was struggling to breathe, said Vyas, president and CEO of the Cancer Center of Middle Georgia, Dublin, and assistant professor at Augusta University in Georgia.

The woman, a single mother, told Vyas about her three young kids at home and asked him, “Doc, do something, please help me,” he recalled.

“Absolutely,” Vyas told her. But he had to be brutally honest about her prognosis and firm that she needed to follow his instructions. “You have a breast cancer I cannot cure,” he said. “All I can do is control the disease.”

From that first day, until the day she died, she came to every appointment and followed the treatment plan Vyas laid out.

For about 2 years, she responded well to treatment. And as the time passed and the trust grew, she began to open up to him. She showed him pictures. She talked about her children and being a mother.

“I’ve got to get my kids in a better place. I’m going to be there for them,” he recalled her saying.

Vyas admired her resourcefulness. She held down a part-time job, working retail and at a local restaurant. She figured out childcare so she could get to her chemotherapy appointments every 3 weeks and manage the copays.

Several years later, when she knew she was approaching the end of her life, she asked Vyas a question that hit hard.

“Doc, I don’t want to die and my kids find me dead. What can we do about it?”

Vyas, who has three daughters, imagined how traumatic this would be for a child. She and Vyas made the shared decision to cease treatment and begin home hospice. When the end was approaching, a hospice worker took over, waiting for bodily functions to cease.

When news of a death comes, “I say a little prayer, it’s almost like a send-off for that soul. That helps me absorb the news ... and let it go.”

But when the bond grows strong over time, as with his patient with breast cancer, Vyas said, “a piece of her is still with me.”

Khan had no relevant disclosures. Boccia and Vyas had no disclosures.

Rose Gerber was 39, mother to a third grader and a kindergartener, when the diagnosis came: Advanced HER2-positive breast cancer.

“On one of my first or second appointments, I took in a little picture of Alexander and Isabella,” Gerber said. Gerber showed her oncologist the picture and told her: “I’ll do anything. I just want to be there for them.”

That was 21 years ago. Today, her current cancer status is “no evidence of disease.”

Over the past 2 decades, Gerber has gotten to be there for her children. Her youngest is now a television producer and her oldest, a CPA.

In that time, Gerber has had one constant: Her oncologist, Kandhasamy Jagathambal, MD, or Dr. Jaga, as she’s often called. 

“I’ve seen multiple physicians over my 21 years, but my oncologist has always been the focal point, guiding me in the right direction,” Gerber said in an interview.

Over the years, Jaga guided Gerber through a range of treatment decisions, including a Herceptin clinical trial that the mom of two views as lifesaving. Jaga often took on the role of both doctor and therapist, even providing comfort in the smaller moments when Gerber would fret about her weight gain.

The oncologist-patient “bond is very, very, very special,” said Gerber, who now works as director of patient advocacy and education at the Community Oncology Alliance.

Gerber isn’t alone in calling out the depth of the oncologist-patient bond.

Over years, sometimes decades, patients and oncologists can experience a whole world together: The treatment successes, relapses, uncertainties, and tough calls. As a result, a deep therapeutic alliance often develops. And with each new hurdle or decision, that collaborative, human connection between doctor and patient continues to form new layers.

“It’s like a shared bonding experience over trauma, like strangers trapped on a subway and then we get out, and we’re now on the other side, celebrating together,” said Saad Khan, MD, an associate professor of medicine (oncology) at Stanford University in California.

 

Connecting Through Stress

Although studies exploring the oncologist-patient bond are limited, some research suggests that a strong therapeutic alliance between patients and oncologists not only provides a foundation for quality care but can also help improve patients’ quality of life, protect against suicidal ideation, and increase treatment adherence.

Because of how stressful and frightening a cancer diagnosis can be, creating “a trusting, uninterrupted, almost sacred environment for them” is paramount for Khan. “I have no doubt that the most important part of their treatment is that they find an oncologist in whom they have total confidence,” Khan wrote in a blog.

The stress that patients with cancer experience is well documented, but oncologists take on a lot themselves and can also experience intense stress (.

“I consider my patient’s battles to be my battles,” Khan wrote.

The stress can start with the daily schedule. Oncologists often have a high volume of patients and tend to spend more time with each individual than most.

According to a 2023 survey, oncologists see about 68 patients a week, on average, but some oncologists, like Khan, have many more. Khan typically sees 20-30 patients a day and continues to care for many over years.

The survey also found that oncologists tend to spend a lot of time with their patients. Compared with other physicians, oncologists are two times more likely to spend at least 25 minutes with each patient.

With this kind of patient volume and time, Khan said, “you’re going to be exhausted.”

What can compound the exhaustion are the occasions oncologists need to deliver bad news — this treatment isn’t working, your cancer has come roaring back and, perhaps the hardest, we have no therapeutic options left. The end-of-life conversations, in particular, can be heartbreaking, especially when a patient is young and not ready to stop trying.

“It can be hard for doctors to discuss the end of life,” Don Dizon, MD, director of the Pelvic Malignancies Program at Lifespan Cancer Institute and director of Medical Oncology at Rhode Island Hospital, Providence, wrote in a column in 2023. Instead, it can be tempting and is often easier to focus on the next treatment, “instilling hope that there’s more that can be done,” even if doing more will only do harm.

In the face of these challenging decisions, growing a personal connection with patients over time can help keep oncologists going.

“We’re not just chemotherapy salesmen,” Khan said in an interview. “We get to know their social support network, who’s going to be driving them [to and from appointments], where they go on vacation, their cat’s name, who their neighbors are.”

 

A ‘Special Relationship’

Ralph V. Boccia, MD, is often asked what he does.

The next question that often comes — “Why do I do what I do?” — is Boccia’s favorite.

“Someone needs to take these patients through their journey,” Boccia, the founder of The Center for Cancer and Blood Disorders, Bethesda, Maryland, typically responds. He also often notes that “it is a special relationship you develop with the patient and their families.”

Boccia thinks about one long-term patient who captures this bond.

Joan Pinson, 70, was diagnosed with multiple myeloma about 25 years ago, when patients’ average survival was about 4 years.

Over a quarter century, Pinson has pivoted to different treatments, amid multiple relapses and remissions. Throughout most of this cancer journey, Boccia has been her primary oncologist, performing a stem cell transplant in 2000 and steering her to six clinical trials.

Her last relapse was 2 years ago, and since then she has been doing well on oral chemotherapy.

“Every time I relapsed, by the next appointment, he’d say, ‘here is what we are going to do,’ ” Pinson recalled. “I never worried, I never panicked. I knew he would take care of me.”

Over the years, Pinson and Boccia have shared many personal moments, sometimes by accident. One special moment happened early on in Pinson’s cancer journey. During an appointment, Boccia had “one ear to the phone” as his wife was about to deliver their first baby, Pinson recalled.

Later, Pinson met that child as a young man working in Boccia’s lab. She has also met Boccia’s wife, a nurse, when she filled in one day in the chemotherapy room.

Boccia now also treats Pinson’s husband who has prostate cancer, and he ruled out cancer when Pinson’s son, now in his 40s, had some worrisome symptoms.

More than 2 decades ago, Pinson told Boccia her goal was to see her youngest child graduate from high school. Now, six grandsons later, she has lived far beyond that goal.

“He has kept me alive,” said Pinson.

Heather K. Schopper, MD, a head and neck surgeon at Penn State Health, Hershey, Pennsylvania, wasn’t long into her career when she began feeling its physical demands. Standing for 12 hours at a time, holding awkward positions for long periods, and working with surgical tables and instruments made for doctors much taller and larger meant severe back, shoulder, and neck pain at the end of every shift.

“You just want to lie down on the floor at the end of the day,” Schopper explained. “The wear and tear of our profession is really challenging.”

Here’s the thing: At the time Schopper wasn’t particularly out of shape. She only knew she needed to build up her body for long days and a long career. What, physically, would that look like?

This was the catalyst for what she calls a “health and fitness journey” that transformed the way she practices.

“Medicine is unique in its physical demands,” said Meghan Wieser, PT, DPT, a doctor of physical therapy at Recharge Health and Fitness in Ellicott City, Maryland. Wieser frequently works with physicians and others in high-stress career environments, and she’s observed the serious toll that physically demanding medical practice can take on the body.

It’s not just about preventing acute or chronic injury, she said. It’s about performing better for longer periods. And every doctor knows the only way to build a more functional body is training.

 

The Fantasy of Physical Perfection vs the Reality of, Well, Reality

Jordan D. Metzl, MD, is a sports medicine physician at Hospital for Special Surgery (HSS) in New York City. He’s also a lifelong triathlete and marathon runner and has parlayed that passion into an online fitness community of more than 10,000 people called Ironstrength. Through that, Metzl has led free exercise classes in Central Park for years. He doesn’t dabble. Three times a year he leads a boot camp class of more than 1000 people on the flight deck of the USS Intrepid on the Hudson River.

“I get it, being a doctor is all about the hours,” he said. “The time sacrifices get brutal and you have to cut something out, sometimes every day. For a lot of us, that’s exercise.”

Metzl understands it so well that he recently began leading twice-monthly boot camp classes just for his HSS physician colleagues on Wednesday mornings. He says those doctors both want and need that extra boost and will be aggressive about making time for it.

“The better shape you’re in, the better job you’ll do as a physician,” he said. “You’ll feel better when the hours get long. In my own career, I have always been a better doctor when I’m active and in shape.”

Knowledge isn’t really the issue for physicians. Reality is. And reality dictates that doctors have just as much issue with achieving consistency as any patient they prescribe exercise to.

Metzl suggests total body functional training to mimic real-world movement, particularly core and lower body to keep you upright for hours at a time. How do you schedule that? He uses early mornings and weekends to train for his races and run his fitness classes, which is why his primary advice is to focus not on the activity, but on time.

“Schedule full workouts when you can and steal the rest,” he said.

Schopper agrees. “You may not be able to fit in 60 minutes of exercise every day, but 20-30 minutes of intentional movement is key,” she explained. “When you have a day off, prioritize a longer session of something you can’t fit in on workdays.”

Those shorter bouts of exercise might include “bookending” the day with 10 minutes of burpees in the morning and then 10 minutes of bodyweight strength moves like planks, push-ups, and air squats in the evening.

“Bodyweight exercises are low-hanging fruit,” said Wieser. “If you’ve got a short window, aim for something that can shoot your heart rate up quickly.”

You can also throw in “movement snacks” throughout the day — skip the elevator and run up a flight of stairs, walk around during a quick lunch break, or throw in a set of jumping jacks between patients. (Don’t worry — you won’t be dripping sweat when they walk in.)

Remember, the rehab room in the orthopedic wing may have a few dumbbells and exercise bands you can utilize when you have 5 extra minutes in your day. “Any way you can squeeze in extra movement counts,” said Wieser.

 

Feats of Strength? Neighborhood Sprints? It All Matters

Kissinger Goldman, DO, a Florida-based ER physician, began his dedication to exercise 17 years ago, after a high-cholesterol diagnosis. “Did I have time to exercise in medical school and residency? Yes,” Goldman admitted. “But I didn’t have the same commitment to my health until I received that number. I set about to change everything.”

Goldman follows the approach of dividing up his exercise routine into short or long sessions, depending on his schedule. “If I’m off, I’ll aim for 30 minutes of cardio and 30 minutes of strength and core work,” he explained. “When I have to work, I’ll do a compressed version of that routine as soon as I wake up, and make sure the cardio is very intense — I’ll sprint in my neighborhood, for instance.”

Matt Klein, a doctor of physical therapy and professor at George Fox University in Newberg, Oregon, who has treated many doctors, says that, when pushed for time, just 20 minutes of “heavy” strength training can deliver good results. “The definition of heavy will vary, but aim for a weight that is challenging, whether a beginner or a more experienced exerciser,” he said. “Most doctors won’t have time to go to the gym, so a simple set of dumbbells or kettlebells will work just fine. The easier it is to access, the more likely you are to do it consistently.”

Klein is a fan of strength training with good reason: “Strength is a predictor of chronic disease, so doing some high-level strength training or power training can go a long way,” he said.

The endorphin high and overall sense of improved well-being are an extra bonus. Goldman credits it with ensuring he rarely misses a workout.

 

Get Hardcore About Sleep

Consider the following passage: “There are clear negative effects of sleep deprivation on performance, including reaction time, accuracy, vigor, submaximal strength, and endurance. Cognitive functions such as judgment and decision-making also suffer.”

Does that sound like how you feel on suboptimal sleep? That’s from an International Journal of Sports Medicine study on the effects of sleep deprivation on athletes.

Athletes aren’t doctors — but when you consider “reaction time, accuracy, endurance, judgment, and decision-making” — doctors could certainly benefit by thinking like athletes.

Schopper is serious about sleep and sets firm boundaries.

“It’s hard,” she admitted. “We want to work, see our families, have fun. But I work hard to say, ‘I’m done,’ and go to bed.”

“Rest is crucial for this job,” agreed Goldman. “If you don’t have adequate sleep, your cortisone levels are going to go up. When you’re exhausted and you’re working, you’re likely to miss something.” Goldman is consistent with early bedtimes around 9:00 or 9:30 PM, and he allows for a bit of “wind-down” time by reading for about 20 minutes before nodding off.

Goldman also sees a link between rest and improved interactions with patients. “There’s a direct correlation between number of hours worked in a row with respect to ‘customer service’ with patients,” he said.

But don’t aim for perfection. Allow some wiggle room for the time you spend asleep, Klein recommends. “We’ve always aimed for 8 hours, but there’s evidence that even 6 or 7 hours can be enough to allow you to recover as needed,” he said. “Optimally, you want that to be uninterrupted, but if not, a 10-minute power nap can help with mental clarity.”

 

Keep Searching, Keep Trying, Keep Training

Schopper was never, nor has she become, a gym rat. Still, “I knew I needed to build upper body strength,” she said. That meant expanding her fitness possibilities beyond the obvious. She discovered aerial arts — intense workouts using straps and other suspension tools to work every muscle in her body while hanging from the ceiling. Increased strength was a given, but she also seriously increased her range of motion.

For Schopper, the improvements to her lifestyle have been game changers. “I still have long days, but I’m no longer sore and tired after them,” she said. “I sleep better and have more energy. I’m proud of myself for putting the effort into this.”

A journey toward health and fitness may look different for everyone, but (as doctors frequently tell their patients) it’s a path anyone can follow.

“Being a doctor is not necessarily good for your health,” said Klein. “The body can handle the job, however, if you train for it.”

Feats of Strength? Neighborhood Sprints? It All Matters

Kissinger Goldman, DO, a Florida-based ER physician, began his dedication to exercise 17 years ago, after a high-cholesterol diagnosis. “Did I have time to exercise in medical school and residency? Yes,” Goldman admitted. “But I didn’t have the same commitment to my health until I received that number. I set about to change everything.”

Goldman follows the approach of dividing up his exercise routine into short or long sessions, depending on his schedule. “If I’m off, I’ll aim for 30 minutes of cardio and 30 minutes of strength and core work,” he explained. “When I have to work, I’ll do a compressed version of that routine as soon as I wake up, and make sure the cardio is very intense — I’ll sprint in my neighborhood, for instance.”

Matt Klein, a doctor of physical therapy and professor at George Fox University in Newberg, Oregon, who has treated many doctors, says that, when pushed for time, just 20 minutes of “heavy” strength training can deliver good results. “The definition of heavy will vary, but aim for a weight that is challenging, whether a beginner or a more experienced exerciser,” he said. “Most doctors won’t have time to go to the gym, so a simple set of dumbbells or kettlebells will work just fine. The easier it is to access, the more likely you are to do it consistently.”

Klein is a fan of strength training with good reason: “Strength is a predictor of chronic disease, so doing some high-level strength training or power training can go a long way,” he said.

The endorphin high and overall sense of improved well-being are an extra bonus. Goldman credits it with ensuring he rarely misses a workout.

 

Get Hardcore About Sleep

Consider the following passage: “There are clear negative effects of sleep deprivation on performance, including reaction time, accuracy, vigor, submaximal strength, and endurance. Cognitive functions such as judgment and decision-making also suffer.”

Does that sound like how you feel on suboptimal sleep? That’s from an International Journal of Sports Medicine study on the effects of sleep deprivation on athletes.

Athletes aren’t doctors — but when you consider “reaction time, accuracy, endurance, judgment, and decision-making” — doctors could certainly benefit by thinking like athletes.

Schopper is serious about sleep and sets firm boundaries.

“It’s hard,” she admitted. “We want to work, see our families, have fun. But I work hard to say, ‘I’m done,’ and go to bed.”

“Rest is crucial for this job,” agreed Goldman. “If you don’t have adequate sleep, your cortisone levels are going to go up. When you’re exhausted and you’re working, you’re likely to miss something.” Goldman is consistent with early bedtimes around 9:00 or 9:30 PM, and he allows for a bit of “wind-down” time by reading for about 20 minutes before nodding off.

Goldman also sees a link between rest and improved interactions with patients. “There’s a direct correlation between number of hours worked in a row with respect to ‘customer service’ with patients,” he said.

But don’t aim for perfection. Allow some wiggle room for the time you spend asleep, Klein recommends. “We’ve always aimed for 8 hours, but there’s evidence that even 6 or 7 hours can be enough to allow you to recover as needed,” he said. “Optimally, you want that to be uninterrupted, but if not, a 10-minute power nap can help with mental clarity.”

 

Keep Searching, Keep Trying, Keep Training

Schopper was never, nor has she become, a gym rat. Still, “I knew I needed to build upper body strength,” she said. That meant expanding her fitness possibilities beyond the obvious. She discovered aerial arts — intense workouts using straps and other suspension tools to work every muscle in her body while hanging from the ceiling. Increased strength was a given, but she also seriously increased her range of motion.

For Schopper, the improvements to her lifestyle have been game changers. “I still have long days, but I’m no longer sore and tired after them,” she said. “I sleep better and have more energy. I’m proud of myself for putting the effort into this.”

A journey toward health and fitness may look different for everyone, but (as doctors frequently tell their patients) it’s a path anyone can follow.

“Being a doctor is not necessarily good for your health,” said Klein. “The body can handle the job, however, if you train for it.”

TOPLINE:

After the US Preventive Services Task Force (USPSTF) in May 2021 lowered from 50 to 45 the recommended age to begin colorectal cancer (CRC) screening for average-risk adults, there was a threefold increase in screening rates among individuals aged 45-49, but disparities by socioeconomic status and locality occurred.

METHODOLOGY:

• Researchers compared absolute and relative changes in screening uptake among average-risk adults 45-49 years between a 20-month period before and a 20-month period after the USPSTF recommendation was issued (May 1, 2018, to December 31, 2019, and May 1, 2021, to December 31, 2022). Data was evaluated bimonthly.
• They analyzed claims data from more than 10.2 million people with private Blue Cross Blue Shield (BCBS) coverage, with about three million eligible for screening during each bimonthly period, both pre- and post-recommendation.
• They used interrupted time-series analysis and autoregressive integrated moving average models to gauge changes in screening rates.

TAKEAWAY:

• Mean CRC screening uptake in average-risk adults 45-49 years increased from 0.50% in the pre-recommendation period to 1.51% post-recommendation, reflecting a significant absolute change of 1.01 percentage points but no significant relative change.
• Adults 45-49 years living in areas with the highest socioeconomic status (SES) had the largest absolute change in screening uptake compared with peers in the lowest SES areas (1.25 vs 0.75 percentage points). Relative changes were not significant.
• The absolute change in screening uptake was higher among individuals in metropolitan areas than individuals in nonmetropolitan areas (1.06 vs 0.73 percentage points). Again, relative changes were not significant.
• The screening uptake rate increased the fastest among those living in the highest SES and metropolitan areas (0.24 and 0.20 percentage points every 2 months, respectively).
• By December 2022 (the end of the post-recommendation period), CRC screening uptake among adults 45-49 years were on par with those seen in adults 50-75 years (2.37% vs 2.4%). Nonetheless, only 11.5% of average-risk adults aged 45-49 years received CRC screening during the post-recommendation period.

IN PRACTICE:

“The threefold increase in screening uptake among average-risk individuals aged 45-49 years reflects an accomplishment, yet evidence of widening disparities based on SDI [Social Deprivation Index] and locality indicate that population subgroups may not be benefiting equally from this change in CRC screening recommendation. Furthermore, given that only 11.5% of average-risk individuals aged 45-49 years during the post-recommendation period received CRC screening before the age of 50 years, targeted initiatives to improve screening in this age group are warranted to reach the national goal of screening 80% of the population in every community,” the researchers wrote.

SOURCE:

The study, with first author Sunny Siddique, MPH, with Yale School of Public Health, New Haven, Connecticut, was published online in JAMA Network Open. 

LIMITATIONS:

Data on race and ethnicity were incomplete, which may have impacted the analysis of disparities. The study cohort may not be fully representative of the general US population because BCBS beneficiaries tend to be younger and more socioeconomically advantaged with employer-based insurance. Specific information on the type of coverage provided by each beneficiary’s insurance plan was not available.

DISCLOSURES:

The study was funded by the National Cancer Institute. The authors declared no relevant conflicts of interest.

Diet is increasingly seen as a modifiable risk factor in prostate cancer.

Recent studies have shown that ultralow-carbohydrate diets, weight loss diets, supplementation with omega-3 fatty acids, pro- and anti-inflammatory diets, fasting, and even tea drinking may affect prostate cancer risk or risk for progression.

In October, a cohort study involving about 900 men under active surveillance for early stage prostate cancers found that those who reported eating a diet that adhered closely to the US government’s recommendations as indicated by the Healthy Eating Index (HEI) saw a lower risk for progression at a median 6.5 months follow-up.

These findings follow results from an observational study, published in May, that followed about 2000 men with locally advanced prostate tumors. Men consuming a primarily plant-based diet (one closely adhering to the plant-based diet index) had less likelihood of progression over a median 6.5 years than those consuming diets low in plant-based foods.

“There is an increasing body of literature that says your diet matters,” said urologist Stephen J. Freedland, MD, of Cedars-Sinai Medical Center in Los Angeles, California, and director of its Center for Integrated Research in Cancer and Lifestyle. “At the same time, there are a lot of things that could explain these associations. People who can afford lots of plant-based foods tend to have higher socioeconomic status, for example.”

What’s needed, Freedland said, are more randomized trials to test the hypotheses emerging from the longitudinal cohort studies. “That’s where I’m going with my own research,” he said. “I’d like to look at a study like [one of these] and design a trial. Let’s say we get half of patients to eat according to the healthy eating index, while half eat whatever they want. Can dietary modification change which genes are turned on and off in a tumor, as a start?”

 

Oncologist and Nutritionist Collaborate on Multiple Studies

Nutritionist Pao-Hwa Lin, PhD, of Duke University in Durham, North Carolina, has been working for several years with Freedland on trials of nutrition interventions. A longtime researcher of chronic disease and diet, she first collaborated with Freedland on a study, published in 2019, that looked at whether insulin could be driven down with diet and exercise in men treated with androgen deprivation therapy.

Not only are high levels of insulin a known contributor to prostate cancer growth, Lin said, but “insulin resistance is a very common side effect of hormone therapy. And we saw that the low carb diet was very helpful for that.” The finding led Freedland and Lin to design further trials investigating carbohydrate restriction in people with prostate cancer.

Lin said randomized trials tend to be smaller and shorter in duration than the observational cohort studies because “interventions like these can be hard to maintain, and recruitment can be hard to sustain. A very well controlled and intensive nutrition intervention is not going to be super long.” Short trial durations also mean that prostate cancer progression can be difficult to capture. Risk for progression has to be measured using surrogate markers, such as the doubling time for prostate-specific antigen (PSA).

In 2020, Freedland and Lin published results from a pilot study of 57 men who had been treated with surgery or radiation for localized prostate cancer but had a PSA recurrence and were randomized to an ultralow-carbohydrate diet or no restrictions for 6 months. The investigators saw that PSA doubling times, an intermediate measure of tumor growth rate, were slower among those consuming the low-carb diet.

Currently they are wrapping up a trial that randomizes men who have been scheduled for radical prostatectomy to daily supplementation with walnuts, a natural source of polyphenols and omega-3 acids. This time, the aim is to determine whether gene expression in tumors changes in response to supplementation.

The researchers are also recruiting for a study in men being treated for metastatic prostate cancer. This study randomizes patients to a fasting-mimicking diet, which is a type of intermittent fasting, or no dietary restrictions for 6 months.

Developed by biologist Valter Longo, PhD, of the University of Southern California, Los Angeles, the fasting-mimicking diet has been shown to boost treatment effects in women with hormone receptor–positive breast cancer. In 2023, Longo and his colleagues published results from a small pilot study of the same diet in men with prostate cancer, reporting some positive metabolic findings.

Longo, who is consulting on Lin and Freedland’s trial, “has proven that the diet is helpful in treatment outcomes for breast cancer. So we connected and decided to test it and see if it’s helpful in prostate cancer as well.”

 

More Than One Approach Likely to Work

Though Lin and Freedland have focused most of their investigations on carbohydrate restriction, neither dismisses the potential for other dietary approaches to show benefit.

“There are two main schools of thought in terms of the relationship between diet and prostate cancer,” Lin said. “One is the insulin angle, and that’s what we hypothesized when we first tested the low-carb diet. The other is the inflammation angle.”

Studies have shown greater adherence to the HEI — a diet quality indicator that favors grains, fruits, dairy, vegetables, beans, and seafood — or the plant-based diet index to be associated with lower biomarkers of inflammation, she noted.

Insulin resistance, Lin explained, “is also highly related to inflammation.” (Several of the diets being investigated in prostate cancer were originally studied in diabetes.)

Moreover, weight loss caused by low-carb diets — or other healthy diets — can have a positive effect on insulin resistance independent of diet composition. “So it is a very complicated picture — and that doesn’t exclude other pathways that could also be contributing,” she said.

On the surface, a low-carb diet that is heavy in eggs, cheeses, and meats would seem to have little in common with the HEI or a plant-based diet. But Freedland noted that there are commonalities among the approaches being studied. “No one’s promoting eating a lot of simple sugars. No one’s saying eat a lot of processed foods. All of these diets emphasize whole, natural foods,” he said.

Lin hopes that she and Freedland will one day be able to test a diet that is both lower carb and anti-inflammatory in men with prostate cancer. “Why not combine the approaches, have all the good features together?” she asked.

But Freeland pointed out and explained why most clinicians don’t make dietary recommendations to their newly diagnosed patients.

“A new prostate cancer patient already gets easily an hour discussion of treatment options, of pros and cons. Patients often become overwhelmed. And then to extend it further to talk about diet, they’ll end up even more overwhelmed.” Moreover, he said, current evidence offers doctors few take-home messages to deliver besides avoiding sugar and processed foods.

Multiple dietary approaches are likely to prove helpful in prostate cancer, and when the evidence for them is better established, patients and their doctors will want to consider lifestyle factors in choosing one. The best diet will depend on a patient’s philosophy, tastes, and willingness to follow it, he concluded.

“At the end of the day I’m not rooting for one diet or another. I just want to get the answers.”

Lin disclosed no financial conflicts of interest. Freedland disclosed serving as a speaker for AstraZeneca, Astellas, and Pfizer and as a consultant for Astellas, AstraZeneca, Bayer, Eli Lilly, Janssen, Merck, Novartis, Pfizer, Sanofi-Aventis, and Sumitomo.

“There are two main schools of thought in terms of the relationship between diet and prostate cancer,” Lin said. “One is the insulin angle, and that’s what we hypothesized when we first tested the low-carb diet. The other is the inflammation angle.”

Studies have shown greater adherence to the HEI — a diet quality indicator that favors grains, fruits, dairy, vegetables, beans, and seafood — or the plant-based diet index to be associated with lower biomarkers of inflammation, she noted.

Insulin resistance, Lin explained, “is also highly related to inflammation.” (Several of the diets being investigated in prostate cancer were originally studied in diabetes.)

Moreover, weight loss caused by low-carb diets — or other healthy diets — can have a positive effect on insulin resistance independent of diet composition. “So it is a very complicated picture — and that doesn’t exclude other pathways that could also be contributing,” she said.

On the surface, a low-carb diet that is heavy in eggs, cheeses, and meats would seem to have little in common with the HEI or a plant-based diet. But Freedland noted that there are commonalities among the approaches being studied. “No one’s promoting eating a lot of simple sugars. No one’s saying eat a lot of processed foods. All of these diets emphasize whole, natural foods,” he said.

Lin hopes that she and Freedland will one day be able to test a diet that is both lower carb and anti-inflammatory in men with prostate cancer. “Why not combine the approaches, have all the good features together?” she asked.

But Freeland pointed out and explained why most clinicians don’t make dietary recommendations to their newly diagnosed patients.

“A new prostate cancer patient already gets easily an hour discussion of treatment options, of pros and cons. Patients often become overwhelmed. And then to extend it further to talk about diet, they’ll end up even more overwhelmed.” Moreover, he said, current evidence offers doctors few take-home messages to deliver besides avoiding sugar and processed foods.

Multiple dietary approaches are likely to prove helpful in prostate cancer, and when the evidence for them is better established, patients and their doctors will want to consider lifestyle factors in choosing one. The best diet will depend on a patient’s philosophy, tastes, and willingness to follow it, he concluded.

“At the end of the day I’m not rooting for one diet or another. I just want to get the answers.”

Lin disclosed no financial conflicts of interest. Freedland disclosed serving as a speaker for AstraZeneca, Astellas, and Pfizer and as a consultant for Astellas, AstraZeneca, Bayer, Eli Lilly, Janssen, Merck, Novartis, Pfizer, Sanofi-Aventis, and Sumitomo.

Microplastics have been found in the lungs, liver, blood, and heart. Now, researchers report they have found the first evidence of the substances in human brains.

In a recent case series study that examined olfactory bulb tissue from deceased individuals, 8 of the 15 decedent brains showed the presence of microplastics, most commonly polypropylene, a plastic typically used in food packaging and water bottles.

Measuring less than 5 mm in size, microplastics are formed over time as plastic materials break down but don’t biodegrade. Exposure to these substances can come through food, air, and skin absorption.

While scientists are learning more about how these substances are absorbed by the body, questions remain about how much exposure is safe, what effect — if any — microplastics could have on brain function, and what clinicians should tell their patients.

 

What Are the Major Health Concerns?

The Plastic Health Council estimates that more than 500 million metric tons of plastic are produced worldwide each year. In addition, it reports that plastic products can contain more than 16,000 chemicals, about a quarter of which have been found to be hazardous to human health and the environment. Microplastics and nanoplastics can enter the body through the air, in food, or absorption through the skin.

A study published in March showed that patients with carotid plaques and the presence of microplastics and nanoplastics were at an increased risk for death or major cardiovascular events.

Other studies have shown a link between these substances and placental inflammation and preterm births, reduced male fertility, and endocrine disruption — as well as accelerated spread of cancer cells in the gut.

There is also evidence suggesting that microplastics may facilitate the development of antibiotic resistance in bacteria and could contribute to the rise in food allergies.

And now, Thais Mauad, MD, PhD, and colleagues have found the substances in the brain.

 

How Is the Brain Affected?

The investigators examined olfactory bulb tissues from 15 deceased Sao Paulo, Brazil, residents ranging in age from 33 to 100 years who underwent routine coroner autopsies. All but three of the participants were men.

Exclusion criteria included having undergone previous neurosurgical interventions. The tissues were analyzed using micro–Fourier transform infrared spectroscopy (µFTIR).

In addition, the researchers practiced a “plastic-free approach” in their analysis, which included using filters and covering glassware and samples with aluminum foil.

Study findings showed microplastics in 8 of the 15 participants — including in the centenarian. In total, there were 16 synthetic polymer particles and fibers detected, with up to four microplastics detected per olfactory bulb. Polypropylene was the most common polymer found (44%), followed by polyamide, nylon, and polyethylene vinyl acetate. These substances are commonly used in a wide range of products, including food packaging, textiles, kitchen utensils, medical devices, and adhesives.

The microplastic particles ranged in length from 5.5 to 26 microns (one millionth of a meter), with a width that ranged from 3 to 25 microns. The mean fiber length and width was 21 and 4 microns, respectively. For comparison, the diameter of one human hair averages about 70 microns, according to the US Food and Drug Administration (FDA).

“To our knowledge, this is the first study in which the presence of microplastics in the human brain was identified and characterized using µFTIR,” the researchers wrote.

 

How Do Microplastics Reach the Brain?

Although the possibility of microplastics crossing the blood-brain barrier has been questioned, senior investigator Mauad, associate professor in the Department of Pathology, the University of Sao Paulo in Brazil, noted that the olfactory pathway could offer an entry route through inhalation of the particles.

This means that “breathing within indoor environments could be a major source of plastic pollution in the brain,” she said in a press release.

“With much smaller nanoplastics entering the body with greater ease, the total level of plastic particles may be much higher. What is worrying is the capacity of such particles to be internalized by cells and alter how our bodies function,” she added.

Mauad said that although questions remain regarding the health implications of their findings, some animal studies have shown that the presence of microplastics in the brain is linked to neurotoxic effects, including oxidative stress.

In addition, exposure to particulate matter has been linked previously to such neurologic conditions as dementia and neurodegenerative conditions such as Parkinson’s disease “seem to have a connection with nasal abnormalities as initial symptoms,” the investigators noted.

While the olfactory pathway appears to be a likely route of exposure the researchers noted that other potential entry routes, including through blood circulation, may also be involved.

The research suggests that inhaling microplastics while indoors may be unavoidable, Mauad said, making it unlikely individuals can eliminate exposure to these substances.

“Everything that surrounds us is plastic. So we can’t really get rid of it,” she said.

 

Are Microplastics Regulated?

The most effective solution would be stricter regulations, Mauad said.

“The industry has chosen to sell many things in plastic, and I think this has to change. We need more policies to decrease plastic production — especially single-use plastic,” she said.

Federal, state, and local regulations for microplastics are “virtually nonexistent,” reported the Interstate Technology and Regulatory Council (ITRC), a state-led coalition that produces documents and trainings related to regulatory issues.

In 2021, the ITRC sent a survey to all US states asking about microplastics regulations. Of the 26 states that responded, only 4 said they had conducted sampling for microplastics. None of the responders indicated they had established any criteria or standards for microplastics, although eight states indicated they had plans to pursue them in the future.

Although federal regulations include the Microbead-Free Waters Act of 2015 and the Save Our Seas Act 2.0, the rules don’t directly pertain to microplastics.

There are also no regulations currently in place regarding microplastics or nanoplastics in food. A report issued in July by the FDA claimed that “the overall scientific evidence does not demonstrate that levels of microplastics or nanoplastics found in foods pose a risk to human health.”

International efforts to regulate microplastics are much further along. First created in 2022, the treaty would forge an international, legally binding agreement.

While it is a step in the right direction, the Plastic Health Council has cautioned about “the omission of measures in draft provisions that fully address the impact of plastic pollution on human health.” The treaty should reduce plastic production, eliminate single-use plastic items, and call for testing of all chemicals in plastics, the council argues.

The final round of negotiations for the UN Global Plastic Treaty is set for completion before the end of the year.

 

What Should Clinicians Know?

Much remains unknown about the potential health effects of microplastic exposure. So how can clinicians respond to questions from concerned patients?

“We don’t yet have enough evidence about the plastic particle itself, like those highlighted in the current study — and even more so when it comes to nanoplastics, which are a thousand times smaller,” said Phoebe Stapleton, PhD, associated professor in the Department of Pharmacology and Toxicology at the Ernest Mario School of Pharmacy at Rutgers University, Piscataway, New Jersey.

“But we do have a lot of evidence about the chemicals that are used to make plastics, and we’ve already seen regulation there from the EPA. That’s one conversation that clinicians could have with patients: about those chemicals,” she added.

Stapleton recommended clinicians stay current on the latest research and be ready to respond should a patient raise the issue. She also noted the importance of exercising caution when interpreting these new findings.

While the study is important — especially because it highlights inhalation as a viable route of entry — exposure through the olfactory area is still just a theory and hasn’t yet been fully proven.

In addition, Stapleton wonders whether there are tissues where these substances are not found. A discovery like that “would be really exciting because that means that that tissue has mechanisms protecting it, and maybe, we could learn more about how to keep microplastics out,” she said.

She would also like to see more studies on specific adverse health effects from microplastics in the body.

Mauad agreed.

“That’s the next set of questions: What are the toxicities or lack thereof in those tissues? That will give us more information as it pertains to human health. It doesn’t feel good to know they’re in our tissues, but we still don’t have a real understanding of what they’re doing when they’re there,” she said.

The current study was funded by the Alexander von Humboldt Foundation and by grants from the Brazilian Research Council and the Soa State Research Agency. It was also funded by the Plastic Soup Foundation — which, together with A Plastic Planet, forms the Plastic Health Council. The investigators and Stapleton reported no relevant financial relationships.
