Cancer survivors: Move more, sit less for a longer life, study says
Being physically active, on the other hand, lowers the risk of early death, new research shows.
What’s “alarming” is that so many cancer survivors have a sedentary lifestyle, Chao Cao and Lin Yang, PhD, with Alberta Health Services in Calgary, who worked on the study, said in an interview.
The American Cancer Society recommends that cancer survivors follow the same physical activity guidance as the general population. The target is 150-300 minutes of moderate activity or 75-150 minutes of vigorous activity each week (or a combination of these).
“Getting to or exceeding the upper limit of 300 minutes is ideal,” Mr. Cao and Dr. Yang say.
Yet in their study of more than 1,500 cancer survivors, more than half (57%) were inactive, reporting no weekly leisure-time physical activity in the past week.
About 16% were “insufficiently” active, or getting less than 150 minutes per week. Meanwhile, 28% were active, achieving more than 150 minutes of weekly physical activity.
Digging deeper, the researchers found that more than one-third of cancer survivors reported sitting for 6-8 hours each day, and one-quarter reported sitting for more than 8 hours per day.
Over the course of up to 9 years, 293 of the cancer survivors died – 114 from cancer, 41 from heart diseases, and 138 from other causes.
After accounting for things that might influence the results, the risk of dying from any cause or cancer was about 65% lower in cancer survivors who were physically active, relative to their inactive peers.
Sitting for long periods was especially risky, according to the study in JAMA Oncology.
Compared with cancer survivors who sat for less than 4 hours each day, cancer survivors who reported sitting for more than 8 hours a day had nearly twice the risk of dying from any cause and more than twice the risk of dying from cancer.
Cancer survivors who sat for more than 8 hours a day, and were inactive or not active enough, had as much as five times the risk of death from any cause or cancer.
“Be active and sit less, move more, and move frequently,” advise Mr. Cao and Dr. Yang. “Avoiding prolonged sitting is essential for most cancer survivors to reduce excess mortality risks.”

Artificial sweeteners: A modifiable cancer risk?
People with higher (above the median) consumption of artificial sweeteners – especially aspartame and acesulfame-potassium (acesulfame-K) – had a 13% higher risk of overall cancer over 8 years than those who did not consume these sweeteners.
Higher consumption of aspartame was associated with a 22% increased risk of breast cancer and a 15% increased risk of obesity-related cancer, compared with not consuming any of these sweeteners.*
These findings from the Nutri-Santé population-based observational study in France were published online March 24, 2022, in PLoS Medicine.
“Our findings do not support the use of artificial sweeteners as safe alternatives for sugar in foods or beverages and provide important and novel information to address the controversies about their potential adverse health effect,” Charlotte Debras, of the French National Institute for Health and Medical Research (Inserm) and Sorbonne Paris Nord University, and colleagues wrote.
“Results from the NutriNet-Santé cohort (n = 102,865) suggest that artificial sweeteners found in many food and beverage brands worldwide may be associated with increased cancer risk, in line with several experimental in vivo/in vitro studies. These findings provide novel information for the re-evaluation of these food additives by health agencies,” they wrote.
Commenting to the U.K. Science Media Center, Duane Mellor, PhD, registered dietitian and senior teaching fellow, Aston (England) University, said: “This study does not prove or even suggest that we should go back to sugar and turn our backs on artificial sweeteners or diet drinks.
“It does, however, suggest that artificial sweeteners are not a perfect replacement for sugar, they come with their own potential risks, as does sugar. The ideal answer is probably to move away from both, however, that may be unappealing to many who like a little sweetness in their life, so ditching the regular or diet soft drink (soda) for water may not be a well-received health message.”
Important analysis, interpret with caution
“I think that this is an important analysis, but the results need to be interpreted with caution,” another expert, John L. Sievenpiper, MD, PhD, associate professor, departments of nutritional sciences and medicine, University of Toronto, said in an interview.
“Large observational studies like this one that assess the exposure to low and no calorie sweeteners with obesity-related chronic diseases are at risk of reverse causality,” he explained. This is “a caveat that is well recognized by investigators in this field ... and guideline and policy makers.”
Reverse causality is a possibility because “it is likely that many high consumers of low- and no-calorie sweeteners (of which aspartame and acesulfame-K are the most common) will be consuming these sweeteners as a weight-loss strategy,” he added, “as opposed to these sweeteners causing obesity and its complications (including cancers).”
His team recently published a Diabetes and Nutrition Study Group–commissioned systematic review and meta-analysis of 17 randomized controlled trials (JAMA Netw Open. 2022;5[3]:e222092). Their findings “suggest that over the moderate term [low- and no-calorie sweetened beverages] are a viable alternative to water as a replacement strategy in adults with overweight or obesity who are at risk for or have diabetes,” states one of two syntheses (the other is in press in Diabetes Care) for the update of the European Association for the Study of Diabetes guidelines coming in the fall of 2022.
“The bottom line” for the current study, according to Dr. Sievenpiper, “is that it is difficult to disentangle the signals for low- and no-calorie sweeteners from obesity itself and the signals for the sugars and calories that they are replacing/displacing in this analysis. Substitution analyses would be useful to address some of these concerns.”
Conflicting results
Recent epidemiologic and animal studies about a possible link between artificial sweeteners and risk of cancer have had conflicting results, and information about specific types of sweeteners and consumption of artificially sweetened foods as well as beverages is lacking, Ms. Debras and colleagues wrote.
They aimed to investigate the associations between intakes of artificial sweeteners (total and the most common ones – aspartame, acesulfame-K, and sucralose) and cancer risk (overall risk and most frequent types – breast, prostate, and obesity-related cancers) in the ongoing NutriNet-Santé study.
“Obesity-related cancers are cancers for which obesity is involved in their etiology as one of the risk (or protective) factors, as recognized by the World Cancer Research Fund (independently of participant BMI [body mass index] status): colorectal, stomach, liver, mouth, pharynx, larynx, esophageal, breast (with opposite associations pre- and post menopause), ovarian, endometrial, and prostate cancers,” the researchers explained.
According to a recent study , “obesity increases the risk of breast cancer in postmenopausal women but, conversely, it appears to be protective in premenopausal women,” Dr. Sievenpiper noted.
The ongoing NutriNet-Santé study was initiated in 2009 to investigate associations between nutrition and health in the French population. Participants aged 18 and older with Internet access enroll voluntarily and self-report medical history and sociodemographic, diet, lifestyle, and health data.
The current cohort included 102,865 adults who enrolled in 2009-2021.
Consumption of artificial sweeteners was determined from repeated 24-hour dietary records that included brand names of processed foods.
At enrollment, participants were an average age of 42 years and 79% were women. They had a mean BMI of 24 kg/m2. On average, they had 5.6 dietary records.
Most participants did not consume artificial sweeteners (63%); those who did were classified as lower consumers (18.5%) or higher consumers (18.5%).
Aspartame was the most common artificial sweetener (58% of intake), followed by acesulfame-K (29%) and sucralose (10%), and these were mostly in soft drinks (53%), table-top sweeteners (29%), and yogurt/cottage cheese (8%).
During a median 7.7-year follow-up, 3,358 incident cancers – 982 breast, 403 prostate, and 2023 obesity-related cancers – were diagnosed in participants who were a mean age of 60.
Compared with nonconsumers, higher consumers of artificial sweeteners had a higher risk of overall cancer (hazard ratio, 1.13; 95% confidence interval, 1.03-1.25; P-trend = .002), after adjusting for age, sex, education, physical activity, smoking, BMI, height, weight gain during follow-up, diabetes, family history of cancer, number of 24-hour dietary records, baseline caloric intake, and consumption of alcohol, sodium, saturated fatty acids, fiber, sugar, fruit and vegetables, whole-grain foods, and dairy products.
Participants who were higher consumers of aspartame had an increased risk of overall cancer (HR, 1.15; 95% CI, 1.03-1.28; P = .002), as did higher consumers of acesulfame-K (HR, 1.13; 95% CI, 1.01-1.26; P = .007), compared with nonconsumers, after adjusting for the multiple variables.
Higher consumers of aspartame had a higher risk of breast cancer (HR, 1.22; 95% CI, 1.01-1.48; P = .036) and obesity-related cancers (HR, 1.15; 95% CI, 1.01-1.32; P = .026) than nonconsumers.
Higher consumers of total artificial sweeteners had a higher risk of obesity-related cancers than nonconsumers (HR, 1.13; 95% CI, 1.00-1.28; P = .036).
The researchers acknowledged that study limitations include potential selection bias, residual confounding, and reverse causality, though sensitivity analyses were performed to address these concerns.
The NutriNet-Santé study was supported by several French public institutions. Ms. Debras was supported by a grant from the French National Cancer Institute. This project has received funding from the European Research Council, the French National Cancer Institute, the French Ministry of Health, and the IdEx Université de Paris. Dr. Sievenpiper has reported receiving funding from the Tate and Lyle Nutritional Research Fund at the University of Toronto, the Nutrition Trialists Fund at the University of Toronto, and the International Sweeteners Association.

How social drivers of health lead to physician burnout
The vast majority of U.S. physicians regularly treat patients with socioeconomic challenges – from financial instability and a lack of transportation to eviction threats and domestic problems – but are deeply frustrated by their inability to adequately address these issues, a new survey has found.
The survey, conducted in February by The Physicians Foundation, queried 1,502 doctors (500 primary care physicians and 1,002 specialists) about their experience with social drivers – also known as determinants – of health (SDOH). Among the key findings: More than 60% of respondents said they had little or no time to effectively address the SDOH needs of their patients, yet nearly 9 in 10 (87%) said they would like to be able to do so in the future.
Most (63%) said they feel burned out when they try to help patients with their SDOH needs; and nearly 7 in 10 (68%) said managing SDOH for their patients has a “major impact” on their mental health and well-being.
This news organization spoke with Gary Price, MD, president of The Physicians Foundation, about the findings.
Q: These issues aren’t new. Why did you undertake this survey now?
The Physicians Foundation has surveyed America’s physicians for a decade on their practice and the broader health care environment, which included questions on SDOH. However, this is the first one we’ve done that concentrated entirely on SDOH. We think it’s particularly timely now.
The COVID-19 pandemic focused a very harsh spotlight on the tremendous impact SDOH can have on patient health, care outcomes, costs, physician burden, and the physician-patient relationship. It’s become increasingly apparent that for our country to achieve health equity and improve our health care system, including physician satisfaction, we must address the impact of SDOH on patients and physicians.
Even before the pandemic, we had an epidemic of physician burnout. That was driven in large part by the huge amount of time being wasted on administrative tasks such as pre-approvals, insurance forms, and working with electronic medical records. Now we’re recognizing that the causes of physician burnout are much larger than that.
Q: The results of the survey show that physicians are seeing the effects of SDOH no matter where they practice – rural (81%), urban (81%), suburban (73%) – how old they are, or their own racial or ethnic heritage. Is that surprising?
I was, in fact, surprised by the pervasiveness. Every physician is seeing the impact of social drivers on their patients every day. For a long time, physicians tried to ignore these problems because they couldn’t deal with them at the practice level; it was too big a task. But if we’re going to decrease the cost of health care and increase the quality of outcomes and decrease the enormous disparities we see, we’re going to have to deal with these SDOH.
I think the problem is grim, but physicians recognize this issue. It’s not one that they traditionally are trained to deal with – and, more importantly, they are not reimbursed on these issues. But despite that, they all want to help.
Q: The survey found that 83% of physicians believed their inability to adequately deal with SDOH moderately (60%) or significantly (23%) contributed to their feelings of burnout. Why do you think physicians find these problems so frustrating and stressful?
The definition of burnout is feeling that you’re being held responsible for things you no longer have any control or authority over. A patient’s inability to find transportation to get to an appointment, or who has financial instability that can lead them to have to make a choice between buying medicine or buying food for their family, isn’t something a physician can change. The overwhelming majority of physicians in our survey not only recognize that their patients have needs in these areas, but they don’t have time to be able to deal with them the way that they’d like to – either the resources aren’t there, or they aren’t effective, or they simply don’t know where to turn.
This phenomenon has been quantified by research. A 2020 study in JAMA, by the Physicians Foundation Center for the Study of Physician Practice and Leadership at Weill Cornell Medicine, found that physicians who had a larger burden of patients with more social needs received lower quality scores from Medicare and were less likely to receive bonuses for the care they provided. But the lower scores were related to the patients’ socioeconomic environment and had nothing do with the quality of the care they received.
Q: Researchers have looked at the relationship between SDOH and burnout, and what happens when physicians incorporate resources to address social issues into their practice. And it seems that doing so can help ease burnout at least a little.
That makes perfect sense. You’re now giving them the ability to intervene and do something about a health-related issue that’s going to help their patients get better quicker. At the same time, addressing these social issues can reduce health care costs to the system while improving outcomes. For example, when a patient with diabetes who needs insulin has their electricity cut off, they can no longer refrigerate the insulin. So simply having their electricity restored could keep them from being hospitalized for a diabetic coma because they weren’t able to follow their treatment.
The Health Leads Grow and Catalyze project, which we helped fund in 2014-2018, trained college students to make lists of key resources patients might require – like food, electricity, or heat – and work with physicians in the emergency room to get a prescription for that need. We’ve seen a very excellent return on investment and it’s now in health systems all over the country.
Q: The survey does a good job of highlighting the nature and scope of the problem, but what about solutions? What, if anything, can physicians be doing now to reduce the burden of SDOH for their patients?
The most important thing we’re doing now is drawing attention to the problem, not only to the impact it’s having on patients’ health but the health and well-being of our physicians.
The greatest challenge physicians said they faced was not having enough time to address these issues in their practice, and that stems directly from a lot of time that gets wasted on other things – preapprovals, inefficient EHRs, checkboxes. Our doctors reported that even when they know where the resources exist, they are hard to access or unavailable when they want them.
Almost all these things are going to require innovative solutions, and in some cases might vary by the individual. With transportation, for example, maybe we need a system like Meals on Wheels, where part of the solution could be a system of volunteer drivers to take patients to appointments. Or we might need more funding for transportation directly aimed at people who don’t have access to a bus line. But when you think about how much a ride in an ambulance costs versus how much it would cost to get someone to the doctor before they got sick enough to require that ambulance, that kind of expenditure makes a lot of sense for driving down individual and system costs.
Q: The problem of unconscious bias in medicine has been receiving increasing attention. Do you think this bias is related to the issues of SDOH the new survey reveals?
Discrimination and racism are examples of SDOH. Implicit bias can happen in any aspect of our lives and interactions with others – so for physicians this can happen with our patients. Our survey didn’t specifically dive into how bias plays a role in addressing the impact of SDOH, but as a society we can no longer ignore any factor that hinders a person from accessing high-quality, cost-effective health care, including our own unconscious bias.

The vast majority of U.S. physicians regularly treat patients with socioeconomic challenges – from financial instability and a lack of transportation to eviction threats and domestic problems – but are deeply frustrated by their inability to adequately address these issues, a new survey has found.
The survey, conducted in February by The Physicians Foundation, queried 1,502 doctors (500 primary care physicians and 1,002 specialists) about their experience with social drivers – also known as determinants – of health (SDOH). Among the key findings: More than 60% of respondents said they had little or no time to effectively address the SDOH needs of their patients, yet nearly 9 in 10 (87%) said they would like to be able to do so in the future.
Most (63%) said they feel burned out when they try to help patients with their SDOH needs; and nearly 7 in 10 (68%) said managing SDOH for their patients has a “major impact” on their mental health and well-being.
This news organization spoke with Gary Price, MD, president of The Physicians Foundation, about the findings.
Q: These issues aren’t new. Why did you undertake this survey now?
The Physicians Foundation has surveyed America’s physicians for a decade on their practice and the broader health care environment, which included questions on SDOH. However, this is the first one we’ve done that concentrated entirely on SDOH. We think it’s particularly timely now.
The COVID-19 pandemic focused a very harsh spotlight on the tremendous impact SDOH can have on patient health, care outcomes, costs, physician burden, and the physician-patient relationship. It’s become increasingly apparent that for our country to achieve health equity and improve our health care system, including physician satisfaction, we must address the impact of SDOH on patients and physicians.
Even before the pandemic, we had an epidemic of physician burnout. That was driven in large part by the huge amount of time being wasted on administrative tasks such as pre-approvals, insurance forms, and working with electronic medical records. Now we’re recognizing that the causes of physician burnout are much larger than that.
Q: The results of the survey show that physicians are seeing the effects of SDOH no matter where they practice – rural (81%), urban (81%), suburban (73%) – how old they are, or their own racial or ethnic heritage. Is that surprising?
I was, in fact, surprised by the pervasiveness. Every physician is seeing the impact of social drivers on their patients every day.

‘My boss is my son’s age’: Age differences in medical practices
Morton J, MD, a 68-year-old cardiologist based in the Midwest, saw things become dramatically worse when his nine-physician practice was taken over by a large health system.
“Everything changed. My partners and I lost a lot of autonomy. We had a say – but not the final say-so in who we hired as medical assistants or receptionists. We had to change how long we spent with patients and justify procedures or tests – not just to the insurance companies, which is an old story, but to our new employer,” said Dr. J, who asked to remain anonymous.
Worst of all, “I had to report to a kid – a doctor in his 30s, someone young enough to be my son, someone with a fraction of the clinical training and experience I had but who now got to tell me what to do and how to run my practice.”
The “final straw” for Dr. J came when the practice had to change to a new electronic health record (EHR) system. “Learning this new system was like pulling teeth,” he said. His youthful supervisor was “obviously impatient and irritated – his whole attitude and demeanor reflected a sense that he was saddled with a dinosaur.”
After much anguishing and soul-searching, Dr. J decided to retire. “I was already close to retirement age, and I thought it would be nice to spend more time with my grandchildren. Feeling so disrespected was simply the catalyst that brought the decision to a head a couple of years sooner than I had planned.”
Getting through a delicate discussion
This unfortunate situation could have been avoided had the younger supervisor shown more sensitivity, says otolaryngologist Mark Wallace, DO.
Dr. Wallace is speaking from personal experience. Early in his career, he was a younger physician who was forced to discuss a practice management issue with an older physician.
Dr. Wallace was a member of a committee that was responsible for “maximizing the efficiency of good care, while still being aware of cost issues.” When the committee “wanted one of the physicians in the group to change their behavior to improve cost savings, it was my job to discuss that with them.”
Dr. Wallace, who today is a locum tenens physician and a medical practice consultant to Physicians Thrive – an advisory group that helps physicians with financial and practice management problems – recalls feeling uncomfortable about broaching the subject to his supervisee. In this case, the older physician was prescribing name brand medications, and the committee that appointed Dr. Wallace wanted him to encourage the physician to prescribe a generic medication first and reserve brand prescriptions only for cases in which the generic was ineffective.
He acknowledges that he thought the generic was equivalent to the branded product in safety and efficacy.
“I always felt this to be a delicate discussion, whatever the age of the physician, because I didn’t like the idea of telling a doctor that they have to change how they practice so as to save money. I would never want anyone to feel they’re providing a lower level of care.”
The fact that this was an older physician – in his 60s – compounded his hesitancy. “Older physicians have a lot more experience than what I had in my 30s,” Dr. Wallace said. “I could talk to them about studies and outcomes and things like that, but a large part of medicine is the experience you gain over time.
“I presented it simply as a cost issue raised by the committee and asked him to consider experimenting with changing his prescribing behavior, while emphasizing that ultimately, it was his decision,” says Dr. Wallace.
The supervisee understood the concern and agreed to the experiment. He ended up prescribing the generic more frequently, although perhaps not as frequently as the committee would have liked.
, says Ted Epperly, MD, a family physician in Boise, Idaho, and president and CEO of Family Medicine Residency of Idaho.
Dr. Wallace said that older physicians, on coming out of training, felt more respected, were better paid, and didn’t have to continually adjust to new regulations and new complicated insurance requirements. Today’s young physicians coming out of training may not find the practice of medicine as enjoyable as their older counterparts did, but they are accustomed to increasingly complex rules and regulations, so it’s less of an adjustment. But many may not feel they want to work 80 hours per week, as their older counterparts did.
Challenges of technology
Technology is one of the most central areas where intergenerational differences play out, says Tracy Clarke, chief human resources officer at Kitsap Mental Health Services, a large nonprofit organization in Bremerton, Wash., that employs roughly 500 individuals. “The younger physicians in our practice are really prepared, already engaged in technology, and used to using technology for documentation, and it is already integrated into the way they do business in general and practice,” she said.
Dr. Epperly noted that Gen X-ers are typically comfortable with digital technology, although not quite as much as the following generation, the millennials, who have grown up with smartphones and computers quite literally at their fingertips from earliest childhood.
Dr. Epperly, now 67, described the experience of having his organization convert to a new EHR system. “Although the younger physicians were not my supervisors, the dynamic that occurred when we were switching to the new system is typical of what might happen in a more formal reporting structure of older ‘supervisee’ and younger supervisor,” he said. In fact, his experience was similar to that of Dr. J.
“Some of the millennials were so quick to learn the new system that they forgot to check in with the older ones about how they were doing, or they were frustrated with our slow pace of learning the new technology,” said Dr. Epperly. “In fact, I was struggling to master it, and so were many others of my generation, and I felt very dumb, slow, and vulnerable, even though I usually regard myself as a pretty bright guy.”
Dr. Epperly encourages younger physicians not to think, “He’s asked me five times how to do this – what’s his problem?” This impatience can be intuited by the older physician, who may take it personally and feel devalued and disrespected.
Joy Engblade, an internal medicine physician and CMO of Northern Inyo Hospital, Bishop, Calif., said that when her institution was transitioning to a new EHR system this past May, she was worried that the older physicians would have the most difficulty.
Ironically, that turned out not to be the case. In fact, the younger physicians struggled more because the older physicians recognized their limitations and “were willing to do whatever we asked them to do. They watched the tutorials about how to use the new EHR. They went to every class that was offered and did all the practice sessions.” By contrast, many of the younger ones thought, “I know how to work an EHR, I’ve been doing it for years, so how hard could it be?” By the time they needed to actually use it, the instructional resources and tutorials were no longer available.
Dr. Epperly’s experience is different. He noted that some older physicians may be embarrassed to acknowledge that they are technologically challenged and may say, “I got it, I understand,” when they are still struggling to master the new technology.
Ms. Clarke notes that the leadership in her organization is younger than many of the physicians who report to them. “For the leadership, the biggest challenge is that many older physicians are set in their ways, and they haven’t really seen a reason to change their practice or ways of doing things.” For example, some still prefer paper charting or making voice recordings of patient visits for other people to transcribe.
Ms. Clarke has some advice for younger leaders: “Really explore what the pain points are of these older physicians. Beyond their saying, ‘because I’ve always done it this way,’ what really is the advantage of, for example, paper charting when using the EHR is more efficient?”
Daniel DeBehnke, MD, is an emergency medicine physician and vice president and chief physician executive for Premier Inc., where he helps hospitals improve quality, safety, and financial performance. Before joining Premier, he was both a practicing physician and CEO of a health system consisting of more than 1,500 physicians.
“Having been on both sides of the spectrum as manager/leader within a physician group, some of whom are senior to me and some of whom are junior, I can tell you that I have never had any issues related to the age gap.” In fact, it is less about age per se and more about “the expertise that you, as a manager, bring to the table in understanding the nuances of the medical practice and for the individual being ‘managed.’ It is about trusting the expertise of the manager.”
Before and after hourly caps
Dr. Engblade regards “generational” issues to be less about age and birth year and more about the cap on hours worked during residency.
Dr. Engblade, who is 45 years old, said she did her internship year with no hourly restrictions. Such restrictions only went into effect during her second year of residency. “This created a paradigm shift in how much people wanted to work and created a consciousness of work-life balance that hadn’t been part of the conversation before,” she said.
When she interviews an older physician, a typical response is, “Of course I’ll be available any time,” whereas younger physicians, who went through residency after hourly restrictions had been established, are more likely to ask how many hours they will be on and how many they’ll be off.
Matt Lambert, MD, an independent emergency medicine physician and CMO of Curation Health, Washington, agreed, noting that differences in the cap on hours during training “can create a bit of an undertow, a tension between younger managers who are better adjusted in terms of work-life balance and older physicians being managed, who have a different work ethic and also might regard their managers as being less trained because they put in fewer hours during training.”
It is also important to be cognizant of differences in style and priorities that each generation brings to the table. Jaciel Keltgen, PhD, assistant professor of business administration, Augustana University, Sioux Falls, S.D., has heard older physicians say, “We did this the hard way, we sacrificed for our organization, and we expect the same values of younger physicians.” The younger ones tend to say, “We need to use all the tools at our disposal, and medicine doesn’t have to be practiced the way it’s always been.”
Dr. Keltgen, whose PhD is in political science and who has studied public administration, said that younger physicians may also question the mores and protocols that older physicians take for granted. For example, when her physician son was beginning his career, he was told by his senior supervisors that although he was “performing beautifully as a physician, he needed to shave more frequently, wear his white coat more often, and introduce himself as ‘Doctor’ rather than by his first name. Although he did wear his white coat more often, he didn’t change how he introduced himself to patients.”
Flexibility and mutual understanding of each generation’s needs, the type, structure, and amount of training they underwent, and the prevailing values will smooth supervisory interactions and optimize outcomes, experts agree.
Every generation’s No. 1 concern
For her dissertation, Dr. Keltgen used a large dataset of physicians and sought to draw a predictive model by generation and gender as to what physicians were seeking in order to be satisfied in their careers. One “overwhelming finding” of her research into generational differences in physicians is that “every single generation and gender is there to promote the health of their patients, and providing excellent care is their No. 1 concern. That is the common focus and the foundation that everyone can build on.”
Dr. J agreed. “Had I felt like a valued collaborator, I might have made a different decision.” He has begun to consider reentering clinical practice, perhaps as locum tenens or on a part-time basis. “I don’t want to feel that I’ve been driven out of a field that I love. I will see if I can find some type of context where my experience will be valued and learn to bring myself up to speed with technology if necessary. I believe I still have much to offer patients, and I would like to find a context to do so.”

Technology is one of the most central areas where intergenerational differences play out, says Tracy Clarke, chief human resources officer at Kitsap Mental Health Services, a large nonprofit organization in Bremerton, Wash., that employs roughly 500 individuals. “The younger physicians in our practice are really prepared, already engaged in technology, and used to using technology for documentation, and it is already integrated into the way they do business in general and practice,” she said.
Dr. Epperly noted that Gen X-ers are typically comfortable with digital technology, although not quite as much as the following generation, the millennials, who have grown up with smartphones and computers quite literally at their fingertips from earliest childhood.
Dr. Epperly, now 67, described the experience of having his organization convert to a new EHR system. “Although the younger physicians were not my supervisors, the dynamic that occurred when we were switching to the new system is typical of what might happen in a more formal reporting structure of older ‘supervisee’ and younger supervisor,” he said. In fact, his experience was similar to that of Dr. J.
“Some of the millennials were so quick to learn the new system that they forgot to check in with the older ones about how they were doing, or they were frustrated with our slow pace of learning the new technology,” said Dr. Epperly. “In fact, I was struggling to master it, and so were many others of my generation, and I felt very dumb, slow, and vulnerable, even though I usually regard myself as a pretty bright guy.”
Dr. Epperly encourages younger physicians not to think, “He’s asked me five times how to do this – what’s his problem?” This impatience can be intuited by the older physician, who may take it personally and feel devalued and disrespected.
Joy Engblade, an internal medicine physician and CMO of Northern Inyo Hospital, Bishop, Calif., said that when her institution was transitioning to a new EHR system this past May, she was worried that the older physicians would have the most difficulty.
Ironically, that turned out not to be the case. In fact, the younger physicians struggled more because the older physicians recognized their limitations and “were willing to do whatever we asked them to do. They watched the tutorials about how to use the new EHR. They went to every class that was offered and did all the practice sessions.” By contrast, many of the younger ones thought, “I know how to work an EHR, I’ve been doing it for years, so how hard could it be?” By the time they needed to actually use it, the instructional resources and tutorials were no longer available.
Dr. Epperly’s experience is different. He noted that some older physicians may be embarrassed to acknowledge that they are technologically challenged and may say, “I got it, I understand,” when they are still struggling to master the new technology.
Ms. Clarke notes that the leadership in her organization is younger than many of the physicians who report to them. “For the leadership, the biggest challenge is that many older physicians are set in their ways, and they haven’t really seen a reason to change their practice or ways of doing things.” For example, some still prefer paper charting or making voice recordings of patient visits for other people to transcribe.
Ms. Clarke has some advice for younger leaders: “Really explore what the pain points are of these older physicians. Beyond their saying, ‘because I’ve always done it this way,’ what really is the advantage of, for example, paper charting when using the EHR is more efficient?”
Daniel DeBehnke, MD, is an emergency medicine physician and vice president and chief physician executive for Premier Inc., where he helps hospitals improve quality, safety, and financial performance. Before joining Premier, he was both a practicing physician and CEO of a health system consisting of more than 1,500 physicians.
“Having been on both sides of the spectrum as manager/leader within a physician group, some of whom are senior to me and some of whom are junior, I can tell you that I have never had any issues related to the age gap.” In fact, it is less about age per se and more about “the expertise that you, as a manager, bring to the table in understanding the nuances of the medical practice and for the individual being ‘managed.’ It is about trusting the expertise of the manager.”
Before and after hourly caps
Dr. Engblade regards “generational” issues to be less about age and birth year and more about the cap on hours worked during residency.
Dr. Engblade, who is 45 years old, said she did her internship year with no hourly restrictions. Such restrictions only went into effect during her second year of residency. “This created a paradigm shift in how much people wanted to work and created a consciousness of work-life balance that hadn’t been part of the conversation before,” she said.
When she interviews an older physician, a typical response is, “Of course I’ll be available any time,” whereas younger physicians, who went through residency after hourly restrictions had been established, are more likely to ask how many hours they will be on and how many they’ll be off.
Matt Lambert, MD, an independent emergency medicine physician and CMO of Curation Health, Washington, agreed, noting that differences in the cap on hours during training “can create a bit of an undertow, a tension between younger managers who are better adjusted in terms of work-life balance and older physicians being managed, who have a different work ethic and also might regard their managers as being less trained because they put in fewer hours during training.”
It is also important to be cognizant of differences in style and priorities that each generation brings to the table. Jaciel Keltgen, PhD, assistant professor of business administration, Augustana University, Sioux Falls, S.D., has heard older physicians say, “We did this the hard way, we sacrificed for our organization, and we expect the same values of younger physicians.” The younger ones tend to say, “We need to use all the tools at our disposal, and medicine doesn’t have to be practiced the way it’s always been.”
Dr. Keltgen, whose PhD is in political science and who has studied public administration, said that younger physicians may also question the mores and protocols that older physicians take for granted. For example, when her physician son was beginning his career, he was told by his senior supervisors that although he was “performing beautifully as a physician, he needed to shave more frequently, wear his white coat more often, and introduce himself as ‘Doctor’ rather than by his first name. Although he did wear his white coat more often, he didn’t change how he introduced himself to patients.”
Flexibility and mutual understanding of each generation’s needs, the type, structure, and amount of training they underwent, and the prevailing values will smooth supervisory interactions and optimize outcomes, experts agree.
Every generation’s No. 1 concern
For her dissertation, Dr. Keltgen used a large dataset of physicians and sought to draw a predictive model by generation and gender as to what physicians were seeking in order to be satisfied in their careers. One “overwhelming finding” of her research into generational differences in physicians is that “every single generation and gender is there to promote the health of their patients, and providing excellent care is their No. 1 concern. That is the common focus and the foundation that everyone can build on.”
Dr. J agreed. “Had I felt like a valued collaborator, I might have made a different decision.” He has begun to consider reentering clinical practice, perhaps as locum tenens or on a part-time basis. “I don’t want to feel that I’ve been driven out of a field that I love. I will see if I can find some type of context where my experience will be valued and learn to bring myself up to speed with technology if necessary. I believe I still have much to offer patients, and I would like to find a context to do so.”

Morton J, MD, a 68-year-old cardiologist based in the Midwest, saw things become dramatically worse when his nine-physician practice was taken over by a large health system.
“Everything changed. My partners and I lost a lot of autonomy. We had a say – but not the final say-so in who we hired as medical assistants or receptionists. We had to change how long we spent with patients and justify procedures or tests – not just to the insurance companies, which is an old story, but to our new employer,” said Dr. J, who asked to remain anonymous.
Worst of all, “I had to report to a kid – a doctor in his 30s, someone young enough to be my son, someone with a fraction of the clinical training and experience I had but who now got to tell me what to do and how to run my practice.”
The “final straw” for Dr. J came when the practice had to change to a new electronic health record (EHR) system. “Learning this new system was like pulling teeth,” he said. His youthful supervisor was “obviously impatient and irritated – his whole attitude and demeanor reflected a sense that he was saddled with a dinosaur.”
After much anguishing and soul-searching, Dr. J decided to retire. “I was already close to retirement age, and I thought it would be nice to spend more time with my grandchildren. Feeling so disrespected was simply the catalyst that brought the decision to a head a couple of years sooner than I had planned.”
Getting through a delicate discussion
This unfortunate situation could have been avoided had the younger supervisor shown more sensitivity, says otolaryngologist Mark Wallace, DO.
Dr. Wallace is speaking from personal experience. Early in his career, he was a younger physician who was forced to discuss a practice management issue with an older physician.
Dr. Wallace was a member of a committee that was responsible for “maximizing the efficiency of good care, while still being aware of cost issues.” When the committee “wanted one of the physicians in the group to change their behavior to improve cost savings, it was my job to discuss that with them.”
Dr. Wallace, who today is a locum tenens physician and a medical practice consultant to Physicians Thrive – an advisory group that helps physicians with financial and practice management problems – recalls feeling uncomfortable about broaching the subject to his supervisee. In this case, the older physician was prescribing name brand medications, and the committee that appointed Dr. Wallace wanted him to encourage the physician to prescribe a generic medication first and reserve brand prescriptions only for cases in which the generic was ineffective.
He acknowledges that he thought the generic was equivalent to the branded product in safety and efficacy.
“I always felt this to be a delicate discussion, whatever the age of the physician, because I didn’t like the idea of telling a doctor that they have to change how they practice so as to save money. I would never want anyone to feel they’re providing a lower level of care.”
The fact that this was an older physician – in his 60s – compounded his hesitancy. “Older physicians have a lot more experience than what I had in my 30s,” Dr. Wallace said. “I could talk to them about studies and outcomes and things like that, but a large part of medicine is the experience you gain over time.
“I presented it simply as a cost issue raised by the committee and asked him to consider experimenting with changing his prescribing behavior, while emphasizing that ultimately, it was his decision,” says Dr. Wallace.
The supervisee understood the concern and agreed to the experiment. He ended up prescribing the generic more frequently, although perhaps not as frequently as the committee would have liked.
, says Ted Epperly, MD, a family physician in Boise, Idaho, and president and CEO of Family Medicine Residency of Idaho.
Dr. Wallace said that older physicians, on coming out of training, felt more respected, were better paid, and didn’t have to continually adjust to new regulations and new complicated insurance requirements. Today’s young physicians coming out of training may not find the practice of medicine as enjoyable as their older counterparts did, but they are accustomed to increasingly complex rules and regulations, so it’s less of an adjustment. But many may not feel they want to work 80 hours per week, as their older counterparts did.

Boring is good. Boring is right. Boring is … interesting
Can you keep it down? I’m trying to be boring
He chides his friends for not looking both ways before crossing the road. He is never questioned by the police because they fall asleep listening to him talk. He has won the office’s coveted perfect attendance award 10 years running. Look out, Dos Equis guy, you’ve got some new competition. That’s right, it’s the most boring man in the world.
For this boring study (sorry, study on boredom) conducted by English researchers and published in Personality and Social Psychology Bulletin, people were surveyed on various jobs and hobbies, ranking them by how exciting or boring they are, as well as how competent someone with those jobs/hobbies would be, their willingness to avoid someone with those jobs/hobbies, and how much they’d need to be paid to spend time with someone who had an undesirable job/hobby.
According to the British public, the most boring person in the world is a religious data analyst who likes to sleep and lives in a small town. In fact, spending time with this person is almost a full-time job on its own: To make it worth their while, survey subjects wanted 35 pounds a day. The boring person also was viewed as less competent, as is anyone with a boring job.
Now, there probably aren’t a lot of religious data analysts out there, but don’t worry, there are plenty of other boring jobs – accounting, tax/insurance, cleaning, and banking rounded out the top five (apparently people don’t like finances) – and hobbies – watching TV, observing animals, and mathematics filled out the top five. In case you’re curious, performing artists, scientists, journalists, health professionals, and teachers were viewed as having exciting jobs; exciting hobbies included gaming, reading, domestic tasks (really?), gardening, and writing.
Lead researcher Wijnand Van Tilburg, PhD, made an excellent point about people with boring jobs: They “have power in society – perhaps we should try not to upset them and stereotype them as boring!”
We think they should lean into it and make The Most Boring Man in the World ads: “When I drive a car off the lot, its value increases because I used the correct lending association. Batman trusts me with his Batmobile insurance. I can make those Cuban cigars tax exempt. Stay financially solvent, my friends.”
Fungi, but make it fashion
Fashion is an expensive and costly industry to sustain. Cotton production takes a toll on the environment, leather production comes with environmental and ethical/moral conundrums, and thanks to fast fashion, about 85% of textiles are being thrown away in the United States.
Researchers at the University of Borås in Sweden, however, have found a newish solution to create leather, cotton, and other textiles. And as with so many of the finer things, it starts with unsold bread from the grocery store.
Akram Zamani, PhD, and her team take that bread and turn it into breadcrumbs, then combine it with water and Rhizopus delemar, a fungus typically found in decaying food. After a couple of days of feasting on the bread, the fungus produces natural fibers made of chitin and chitosan that accumulate in the cell walls. After proteins, lipids, and other byproducts are removed, the team is left with a jelly-like substance made of those fibrous cell walls that can be spun into a fabric.
The researchers started small with very thin nonpliable sheets, but with a little layering by using tree tannins for softness and alkali for strength, their fungal leather is more like real leather than competing fungal leathers. Not to mention its being able to be produced in a fraction of the time.
This new fungal leather is fast to produce, it’s biodegradable, and it uses only natural ingredients to treat the materials. It’s the ultimate environmental fashion statement.
Who’s afraid of cancer? Not C. elegans
And now, we bring you part 2 of our ongoing series: Creatures that can diagnose cancer. Last week, we discovered that ants are well on their way to replacing dogs in our medical labs and in our hearts. This week, we present the even-more-lovable nematode.
The soil-dwelling nematode Caenorhabditis elegans, which is less than 1 mm long, is known to be “attracted or repelled by certain odors, so we came up with an idea that the roundworm could be used to detect lung cancer,” Shin Sik Choi, PhD, of Myongji University in South Korea, who is the project’s principal investigator, said in a statement on Eurekalert.
Dr. Choi’s team created a “worm-on-a-chip” that allowed the nematodes to choose between a drop of culture media from lung cancer cells and media from normal lung fibroblasts. An hour after being placed in the chip’s central chamber, more nematodes had crawled toward the lung cancer media than the normal-cell sample.
The investigators estimate that the device is about 70% effective at detecting cancer cells, but “they hope to increase both the accuracy and sensitivity of the method by using worms that were previously exposed to cancer cell media and therefore have a ‘memory’ of cancer-specific odor molecules,” according to the statement from the American Chemical Society.
Since C. elegans is easy to grow in a lab and, apparently, easy to train, the researchers hope that the worm-on-a-chip can become a quick, easy, economical, and noninvasive cancer screen.
So watch out cancer, because we never bet against the creepy crawlies.
Mosquitoes have us figured out
We are nearing mosquito season; quite possibly the most annoying and itchy time of the year. We stock up on bottles of bug spray, but somehow we still get bite after bite. It appears that mosquitoes are basically able to ignore our bug sprays, which explains why we’re still covered in bites after the Fourth of July fireworks. It turns out mosquitoes are more complex than we thought for such tiny creatures.
There’s plenty of research on the best ways to keep mosquitoes away, because not only are they incredibly annoying, but they also carry potentially harmful diseases. In a recent experiment, researchers used mosquitoes that were genetically modified to have an excessive amount of an odor receptor called AgOR2, which responds to the smell of humans.
“AgOR2 overexpression threw a wrench in the whole system by inactivating olfactory receptors in these mosquitoes,” Christopher Potter, PhD, associate professor of neuroscience at Johns Hopkins University, said in a written statement.
After testing how these genetically modified mosquitoes reacted to some of the common smells of bug spray such as lemongrass, they discovered that it’s easy for the mosquitoes to ignore the smell. We wish it were that easy for us to ignore that chemically fruity smell.
Researchers continue to work hard to figure out how to repel mosquitoes and we’re rooting for them as summer approaches, despite the mosquito’s status as a creepy crawly.

After proteins, lipids, and other byproducts are removed, the team is left with a jelly-like substance made of those fibrous cell walls that can be spun into a fabric.
The researchers started small with very thin nonpliable sheets, but with a little layering by using tree tannins for softness and alkali for strength, their fungal leather is more like real leather than competing fungal leathers. Not to mention its being able to be produced in a fraction of the time.
This new fungal leather is fast to produce, it’s biodegradable, and it uses only natural ingredients to treat the materials. It’s the ultimate environmental fashion statement.
Who’s afraid of cancer? Not C. elegans
And now, we bring you part 2 of our ongoing series: Creatures that can diagnose cancer. Last week, we discovered that ants are well on their way to replacing dogs in our medical labs and in our hearts. This week, we present the even-more-lovable nematode.
The soil-dwelling nematode Caenorhabditis elegans, which is less than 1 mm long, is known to be “attracted or repelled by certain odors, so we came up with an idea that the roundworm could be used to detect lung cancer,” Shin Sik Choi, PhD, of Myongji University in South Korea, who is the project’s principal investigator, said in a statement on Eurekalert.
Dr. Choi’s team created a “worm-on-a-chip” that allowed the nematodes to choose between a drop of culture media from lung cancer cells and media from normal lung fibroblasts. An hour after being placed in the chip’s central chamber, more nematodes had crawled toward the lung cancer media than the normal-cell sample.
The investigators estimate that the device is about 70% effective at detecting cancer cells, but “they hope to increase both the accuracy and sensitivity of the method by using worms that were previously exposed to cancer cell media and therefore have a ‘memory’ of cancer-specific odor molecules,” according to the statement from the American Chemical Society.
Since C. elegans is easy to grow in a lab and, apparently, easy to train, the researchers hope that the worm-on-a-chip can become a quick, easy, economical, and noninvasive cancer screen.
So watch out cancer, because we never bet against the creepy crawlies.
Mosquitoes have us figured out
We are nearing mosquito season; quite possibly the most annoying and itchy time of the year. We stock up on bottles of bug spray, but somehow we still get bite after bite. It appears that mosquitoes are basically able to ignore our bug sprays, which explains why we’re still covered in bites after the Fourth of July fireworks. It turns out mosquitoes are more complex than we thought for such tiny creatures.
There’s plenty of research on the best ways to keep mosquitoes away, because not only are they incredibly annoying, but they also carry potentially harmful diseases. In a recent experiment, researchers used mosquitoes that were genetically modified to have an excessive amount of an odor receptor called AgOR2, which responds to the smell of humans.
“AgOR2 overexpression threw a wrench in the whole system by inactivating olfactory receptors in these mosquitoes,” Christopher Potter, PhD, associate professor of neuroscience at Johns Hopkins University, said in a written statement.
After testing how these genetically modified mosquitoes reacted to some of the common smells of bug spray such as lemongrass, they discovered that it’s easy for the mosquitoes to ignore the smell. We wish it were that easy for us to ignore that chemically fruity smell.
Researchers continue to work hard to figure out how to repel mosquitoes and we’re rooting for them as summer approaches, despite the mosquito’s status as a creepy crawly.
Natural, vaccine-induced, and hybrid immunity to COVID-19
Seroprevalence surveys suggest that, from the beginning of the pandemic to 2022, more than a third of the global population had been infected with SARS-CoV-2. As large numbers of people continue to be infected, the efficacy and duration of natural immunity, in terms of protection against SARS-CoV-2 reinfections and severe disease, are of crucial significance. The virus’s epidemiologic trajectory will be influenced by the trends in vaccine-induced and hybrid immunity.
Omicron’s immune evasion
Cases of SARS-CoV-2 reinfection are increasing around the world. According to data from the U.K. Health Security Agency, 650,000 people in England have been infected twice, and most of them were reinfected in the past 2 months. Before mid-November 2021, reinfections accounted for about 1% of reported cases, but the rate has now increased to around 10%. The reinfection risk was 16 times higher between mid-December 2021 and early January 2022. Experts believe that this spike in reinfections is related to the spread of Omicron, which overtook Delta as the dominant variant. Nonetheless, other aspects should also be considered.
Omicron’s greater propensity to spread is not unrelated to its ability to evade the body’s immune defenses. This aspect was raised in a letter recently published in the New England Journal of Medicine. The authors reported that the effectiveness of previous infection in preventing reinfection against the Alpha, Beta, and Delta variants was around 90%, but it was only 56% against Omicron.
Natural immunity
Natural immunity showed roughly similar effectiveness regarding protection against reinfection across different SARS-CoV-2 variants, with the exception of the Omicron variant. The risk of hospitalization and death was also reduced in SARS-CoV-2 reinfections versus primary infections. Observational studies indicate that natural immunity may offer equal or greater protection against SARS-CoV-2 infections, compared with immunization with two doses of an mRNA vaccine, but the data are not fully consistent.
Natural immunity seems to be relatively long-lasting. Data from Denmark and Austria show no evidence that protection against reinfections wanes after 6 months. Some investigations indicate that protection against reinfection is lowest 4-5 months after initial infection and increases thereafter, a finding that might hypothetically be explained by persistent viral shedding; that is, misclassification of prolonged SARS-CoV-2 infections as reinfections. While no comparison was made against information pertaining to unvaccinated, not previously-infected individuals, preliminary data from Israel suggest that protection from reinfection can decrease from 6 to more than 12 months after the first SARS-CoV-2 infection. Taken together, epidemiologic studies indicate that protection against reinfections by natural immunity lasts over 1 year with only moderate, if any, decline over this period. Among older individuals, immunocompromised patients, and those with certain comorbidities or exposure risk (for example, health care workers), rates of reinfection may be higher. It is plausible that reinfection risk may be a function of exposure risk.
There is accumulating evidence that reinfections may be significantly less severe than primary infections with SARS-CoV-2. Reduced clinical severity of SARS-CoV-2 reinfections naturally also makes sense from a biologic point of view, inasmuch as a previously primed immune system should be better prepared for a rechallenge with this virus.
Vaccine-induced immunity
The short-term (<4 months) efficacy of mRNA vaccines against SARS-CoV-2 is high and varies from 94.1% (Moderna) to 95% (BioNTech/Pfizer). This has been confirmed by randomized controlled trials and was subsequently confirmed in effectiveness studies in real-world settings. Waning efficacy was observed with respect to protection against SARS-CoV-2 infections (for example, only approximately 20% after about half a year in Qatar), whereas protection against severe disease was either sustained or showed only a moderate decline.
In individuals who received two doses of the BioNTech/Pfizer vaccine at least 5 months earlier, an additional vaccine dose, a so-called booster, significantly lowered mortality and severe illness. These findings suggest that the booster restored and probably exceeded the initial short-term efficacy of the initial vaccination.
Data are still emerging regarding the efficacy of boosters against the Omicron variants. Preliminary data suggest a far lower ability to restore protection from infection and vaccination. However, fatalities and hospitalizations remain low.
Natural immunity vs. vaccine-induced immunity
Comparisons of natural immunity with vaccine-induced immunity are complicated by a series of biases and by combinations of biases – for example, the biases of comparisons between infected and uninfected, plus the biases of comparisons between vaccinated and nonvaccinated, with strong potential selection biases and confounding. Of particular note, the proportion of people previously infected and/or vaccinated may influence estimates of effectiveness. Regarding this point, one study compared unvaccinated patients with a prior SARS-CoV-2 infection and vaccinated individuals followed up from a week after the second vaccine dose onward versus a group of unvaccinated, not previously infected individuals. The findings showed that, compared with unvaccinated, not previously infected individuals, the natural immunity group and the vaccinated group had similar protection of 94.8% and 92.8% against infection, of 94.1% and 94.2% against hospitalization, and of 96.4% and 94.4% against severe illness, respectively.
Hybrid immunity
The combination of a previous SARS-CoV-2 infection and a respective vaccination is called hybrid immunity. This combination seems to confer the greatest protection against SARS-CoV-2 infections, but several knowledge gaps remain regarding this issue.
Data from Israel showed that, when the time since the last immunity-conferring event (either primary infection or vaccination) was the same, the rates of SARS-CoV-2 infections were similar in the following groups: individuals who had a previous infection and no vaccination, individuals who had an infection and were then vaccinated with a single dose after at least 3 months, and individuals who were vaccinated (two doses) and then infected. Severe disease was relatively rare overall.
Data on the efficacy of hybrid immunity point in the direction of hybrid immunity being superior, as compared with either vaccine-induced (without a booster) immunity or natural immunity alone. Timing and mode of vaccination of previously infected individuals to achieve optimal hybrid immunity are central questions that remain to be addressed in future studies.
Given that vaccination rates are continuously increasing and that, by the beginning of 2022, perhaps half or more of the global population had already been infected with SARS-CoV-2, with the vast majority of this group not being officially detected, it would appear logical that future infection waves, even with highly transmissible variants of SARS-CoV-2, may be limited with respect to their maximum potential health burden. The advent of Omicron suggests that massive surges can occur even in populations with extremely high rates of previous vaccination and variable rates of prior infections. However, even then, the accompanying burden of hospitalizations and deaths is far less than what was seen in 2020 and 2021. One may argue that the pandemic has already transitioned to the endemic phase and that Omicron is an endemic wave occurring in the setting of already widespread population immunity.

‘Profound implications’: COVID ups diabetes risk 40% a year later
COVID-19 infection appears to significantly raise the risk for diabetes by about 40% at 1 year, indicate new data from a very large Veterans Administration population.
“If patients have a prior history of COVID-19, that’s a risk factor for diabetes and they should certainly be screened for diabetes,” study coauthor Ziyad Al-Aly, MD, a nephrologist and chief of research and development at VA St. Louis Health Care, told this news organization.
“It’s still premature to make guidelines. I think we have to process the data landscape to understand what this all really means, but it’s really, really clear that all these roads are pointing in one direction, that COVID-19 increases the risk of diabetes up to a year later. The risk is small but not negligible,” he said.
The database includes over 8 million people and 180,000 with a prior COVID-19 diagnosis. Significantly increased diabetes risks compared to those not infected ranging from 31% to more than double were found in an analysis of subgroups based on diabetes risk score, body mass index, age, race, prediabetes status, and deprivation level, even after adjustment for confounding factors.
There was a gradient of diabetes risk by COVID-19 severity – i.e., whether patients had not been hospitalized, had been hospitalized, or stayed in intensive care – but a significant excess diabetes burden was seen even among those with “mild” COVID-19. The diabetes risk was also elevated compared to both contemporary and historical controls.
The study was published March 21 in The Lancet Diabetes & Endocrinology, by Yan Xie, MPH, also of VA St Louis Health Care, along with Dr. Al-Aly.
The data align with those from another study just published from a nationwide German primary care database. That study was smaller and of shorter duration than the new VA study but consistent, said Dr. Al-Aly, a clinical epidemiologist at Washington University, St. Louis.
Millions more with new diabetes as late manifestation of COVID-19
“Millions of people in the U.S. have had COVID-19, so this is going to translate to literally millions more people with new-onset diabetes. Better to identify them early so they can be adequately treated,” Dr. Al-Aly said in an interview.
“The long-term implications of SARS-CoV-2 infection increasing diabetes risk are profound,” Venkat Narayan, MD, and Lisa R. Staimez, PhD, both of the Rollins School of Public Health and Emory Global Diabetes Research Center at Emory University, Atlanta, said in an accompanying editorial.
“With large and growing numbers of people worldwide infected with SARS-CoV-2 (434,154,739 cumulative cases by Feb. 28, 2022), any COVID-19-related increases in diabetes incidence could lead to unprecedented cases of diabetes worldwide – wreaking havoc on already over-stretched and under-resourced clinical and public health systems globally, with devastating tolls in terms of deaths and suffering,” they added.
Medscape Medical News contributor Eric Topol MD, of Scripps Research Institute, La Jolla, Calif., agrees. He said these new data “are most profound. The researchers found a 40% increase in diabetes that wasn’t present at 1 month after COVID-19 but at 1 year, it was. Some kind of late manifestation is happening here.”
Dr. Al-Aly told this news organization that the mechanisms for the association are unknown and likely to be heterogeneous. Among the people who already had risk factors for type 2 diabetes, such as obesity or metabolic syndrome, SARS-CoV-2 could simply accelerate that process and “put them over the edge” to overt diabetes.
However, for those without diabetes risk factors, “COVID-19 with all the inflammation it provokes in the body could be leading to de novo disease.” (Diabetes status was ascertained by ICD-10 codes and only about 0.70% of the total were recorded as type 1 diabetes. But, since autoantibody testing wasn’t routinely conducted, it’s unknown how many of the cases may have been type 1 misclassified as type 2, Dr. Al-Aly acknowledged.)
Diabetes risk significantly increased after COVID-19 in all analyses
The analysis included 181,280 patients in the U.S. Department of Veterans Affairs health care database with a COVID-19 diagnosis who survived for at least 30 days afterward during March 2020 through Sept. 30, 2021, with 4,118,441 contemporary controls without COVID-19 seen during 2019, and a historical control group of 4,286,911 people seen at the VA in 2017. Average follow-up was about a year.
Compared with the contemporary controls, the COVID-19 group had an excess diabetes burden of 13.46 per 1,000 person-years with a hazard ratio of 1.40. They had an increased 12.35 per 1,000 person-year risk for incident use of glucose-lowering medications, with a hazard ratio of 1.85. Similar results were seen with the historical controls.
Subgroup analyses showed an increased risk for diabetes following COVID-19 infection by age (≤ 65 years and > 65 years), race (White and Black), sex (male and female), BMI categories (> 18.5 to ≤ 25 kg/m², > 25 to ≤ 30 kg/m², and > 30 kg/m²), and area deprivation index quartiles. The increased risk was also seen across diabetes risk score quartiles.
Notably, COVID-19 significantly elevated the diabetes risk by 59% even for the subgroup with BMI between 18 and 25 kg/m², and by 38% among those with the lowest diabetes risk score quartile.
The COVID-19 population included 162,096 who were not hospitalized, 15,078 hospitalized, and 4,106 admitted to intensive care. Here, the hazard ratios for diabetes compared to the contemporary controls were 1.25, 2.73, and 3.76, respectively, all significant.
Dr. Al-Aly said that his group is now further analyzing the VA data for other outcomes including cardiovascular disease and kidney disease, as well as the now well-documented long COVID symptoms including fatigue, pain, and neurocognitive dysfunction.
They’re also investigating the impact of the COVID-19 vaccine to see whether the risks are mitigated in the case of breakthrough infections: “We’re doing a broad systematic assessment. The next paper will be more comprehensive.”
Dr. Narayan and Dr. Staimez wrote: “The potential connection between COVID-19 and diabetes highlights that infectious diseases (eg, SARS-CoV-2) and chronic diseases (eg, diabetes) cannot be viewed in siloes. When we emerge out of the pandemic, the much-neglected non-communicable diseases, such as type 2 diabetes, will continue their relentless trajectory, possibly in an accelerated manner, as the leading burdens of global health.”
Dr. Al-Aly declared support from the U.S. Department of Veterans Affairs for the submitted work. He has received consultation fees from Gilead Sciences and funding (unrelated to this work) from Tonix Pharmaceuticals. He is a member of the board of directors for Veterans Research and Education Foundation of Saint Louis, associate editor for the Journal of the American Society of Nephrology, and a member of multiple editorial boards. Dr. Narayan and Dr. Staimez have received support from the National Institutes of Health.

The researchers found a 40% increase in diabetes that wasn’t present at 1 month after COVID-19 but at 1 year, it was. Some kind of late manifestation is happening here.”
Dr. Al-Aly told this news organization that the mechanisms for the association are unknown and likely to be heterogeneous. Among the people who already had risk factors for type 2 diabetes, such as obesity or metabolic syndrome, SARS-CoV-2 could simply accelerate that process and “put them over the edge” to overt diabetes.
However, for those without diabetes risk factors, “COVID-19 with all the inflammation it provokes in the body could be leading to de novo disease.” (Diabetes status was ascertained by ICD-10 codes and only about 0.70% of the total were recorded as type 1 diabetes. But, since autoantibody testing wasn’t routinely conducted, it’s unknown how many of the cases may have been type 1 misclassified as type 2, Dr. Al-Aly acknowledged.)
Diabetes risk significantly increased after COVID-19 in all analyses
The analysis included 181,280 patients in the U.S. Department of Veterans Affairs health care database with a COVID-19 diagnosis who survived for at least 30 days afterward during March 2020 through Sept. 30, 2021, with 4,118,441 contemporary controls without COVID-19 seen during 2019, and a historical control group of 4,286,911 people seen at the VA in 2017. Average follow-up was about a year.
Compared with the contemporary controls, the COVID-19 group had an excess diabetes burden of 13.46 per 1,000 person-years with a hazard ratio of 1.40. They had an increased 12.35 per 1,000 person-year risk for incident use of glucose-lowering medications, with a hazard ratio of 1.85. Similar results were seen with the historical controls.
Subgroup analyses showed an increased risk for diabetes following COVID-19 infection by age (≤ 65 years and > 65 years), race (White and Black), sex (male and female), BMI categories (> 18.5 to ≤ 25 kg/m², > 25 to ≤ 30 kg/m², and > 30 kg/m²), and area deprivation index quartiles. The increased risk was also seen across diabetes risk score quartiles.
Notably, COVID-19 significantly elevated the diabetes risk by 59% even for the subgroup with BMI between 18 and 25 kg/m², and by 38% among those with the lowest diabetes risk score quartile.
The COVID-19 population included 162,096 who were not hospitalized, 15,078 hospitalized, and 4,106 admitted to intensive care. Here, the hazard ratios for diabetes compared to the contemporary controls were 1.25, 2.73, and 3.76, respectively, all significant.
Dr. Al-Aly said that his group is now further analyzing the VA data for other outcomes including cardiovascular disease and kidney disease, as well as the now well-documented long COVID symptoms including fatigue, pain, and neurocognitive dysfunction.
They’re also investigating the impact of the COVID-19 vaccine to see whether the risks are mitigated in the case of breakthrough infections: “We’re doing a broad systematic assessment. The next paper will be more comprehensive.”
Dr. Narayan and Dr. Staimez wrote: “The potential connection between COVID-19 and diabetes highlights that infectious diseases (eg, SARS-CoV-2) and chronic diseases (eg, diabetes) cannot be viewed in siloes. When we emerge out of the pandemic, the much-neglected non-communicable diseases, such as type 2 diabetes, will continue their relentless trajectory, possibly in an accelerated manner, as the leading burdens of global health.”
Dr. Al-Aly declared support from the U.S. Department of Veterans Affairs for the submitted work. He has received consultation fees from Gilead Sciences and funding (unrelated to this work) from Tonix Pharmaceuticals. He is a member of the board of directors for Veterans Research and Education Foundation of Saint Louis, associate editor for the Journal of the American Society of Nephrology, and a member of multiple editorial boards.

COVID-19 infection appears to significantly raise the risk for diabetes by about 40% at 1 year, indicate new data from a very large Veterans Administration population.
“If patients have a prior history of COVID-19, that’s a risk factor for diabetes and they should certainly be screened for diabetes,” study coauthor Ziyad Al-Aly, MD, a nephrologist and chief of research and development at VA St. Louis Health Care, told this news organization.
“It’s still premature to make guidelines. I think we have to process the data landscape to understand what this all really means, but it’s really, really clear that all these roads are pointing in one direction, that COVID-19 increases the risk of diabetes up to a year later. The risk is small but not negligible,” he said.
The database includes over 8 million people and 180,000 with a prior COVID-19 diagnosis. Significantly increased diabetes risks compared to those not infected ranging from 31% to more than double were found in an analysis of subgroups based on diabetes risk score, body mass index, age, race, prediabetes status, and deprivation level, even after adjustment for confounding factors.
There was a gradient of diabetes risk by COVID-19 severity – i.e., whether patients had not been hospitalized, had been hospitalized, or stayed in intensive care – but a significant excess diabetes burden was seen even among those with “mild” COVID-19. The diabetes risk was also elevated compared to both contemporary and historical controls.
The study was published March 21 in The Lancet Diabetes & Endocrinology, by Yan Xie, MPH, also of VA St Louis Health Care, along with Dr. Al-Aly.
The data align with those from another study just published from a nationwide German primary care database. That study was smaller and of shorter duration than the new VA study but consistent, said Dr. Al-Aly, a clinical epidemiologist at Washington University, St. Louis.
Millions more with new diabetes as late manifestation of COVID-19
“Millions of people in the U.S. have had COVID-19, so this is going to translate to literally millions more people with new-onset diabetes. Better to identify them early so they can be adequately treated,” Dr. Al-Aly said in an interview.
“The long-term implications of SARS-CoV-2 infection increasing diabetes risk are profound,” Venkat Narayan, MD, and Lisa R. Staimez, PhD, both of the Rollins School of Public Health and Emory Global Diabetes Research Center at Emory University, Atlanta, said in an accompanying editorial.

FROM THE LANCET DIABETES & ENDOCRINOLOGY
Mild COVID-19 infection linked to later type 2 diabetes
People who recover from a mild case of COVID-19 appear to have an increased risk for subsequent new-onset type 2 diabetes but not other types of diabetes, new data suggest.
“If confirmed, the results of the present study indicate that diabetes screening in individuals who have recovered from even mild COVID-19 should be recommended,” say Wolfgang Rathmann, MD, of the Leibniz Center for Diabetes Research at Heinrich Heine University, Düsseldorf, Germany, and colleagues.
The findings, from a nationwide primary care database in Germany, were recently published in Diabetologia.
These primary care data align with those from other studies of more seriously ill patients with COVID-19 that found increased rates of type 2 diabetes diagnoses in the subsequent months following illness, they point out.
“COVID-19 infection may lead to diabetes by upregulation of the immune system after remission, which may induce pancreatic beta-cell dysfunction and insulin resistance, or patients may have been at risk for developing diabetes due to having obesity or prediabetes, and the stress COVID-19 put on their bodies sped it up,” said Dr. Rathmann in a press release.
However, because the patients with COVID-19 in the study were only followed for about 3 months, “further follow-up is needed to understand whether type 2 diabetes after mild COVID-19 is just temporary and can be reversed after they have fully recovered or whether it leads to a chronic condition,” he noted.
Increase in type 2 diabetes 3 months after mild COVID-19
The retrospective cohort analysis was performed using data from the Disease Analyzer, a representative panel of 1,171 physician practices in Germany, from March 2020 to January 2021, with follow-up through July 2021.
Individuals with a history of COVID-19 or diabetes and those taking corticosteroids within 30 days after the index dates were excluded.
A total of 35,865 patients with confirmed SARS-CoV-2 infection were propensity score-matched on a one-to-one basis for sex, age, health insurance, and comorbidities with those who had acute respiratory tract infections (controls) but were COVID-19 negative. Median follow-up was 119 days for the COVID-19 group and 161 days for controls.
There was a 28% increased risk of type 2 diabetes for those who had COVID-19 versus controls (15.8 per 1,000 person-years vs. 12.3 per 1,000 person-years, respectively, which was significantly different, and an incidence rate ratio of 1.28).
The incidence of other types of diabetes or unspecified diabetes for the COVID-19 and control groups did not differ significantly (4.3 per 1,000 person-years vs. 3.7 per 1,000 person-years; IRR, 1.17).
Similar findings were seen in sensitivity analyses by glucose-lowering medication prescriptions and by ICD-10 codes.
Although type 2 diabetes is not likely to be a problem for the vast majority of people who have mild COVID-19, the authors recommend that anyone who has recovered from COVID-19 be aware of the warning signs and symptoms such as fatigue, frequent urination, and increased thirst, and seek treatment right away.
CoviDiab registry tracking type 1 and type 2 diabetes
Over the course of the pandemic, there have been conflicting data on whether COVID-19 induces or reveals a propensity for type 1 and type 2 diabetes.
The CoviDiab global registry is tracking this and will include diabetes type for adults and children.
The aim is to have “as many as possible cases of new-onset diabetes for which we can have also a minimum set of clinical data including type of diabetes and A1c,” coprincipal investigator Francesco Rubino, MD, of King’s College London, previously told this news organization.
“By looking at this information we can infer whether a role of COVID-19 in triggering diabetes is clinically plausible – or not – and what type of diabetes is most frequently associated with COVID-19.”
Rubino said that the CoviDiab team is approaching the data with the assumption that, at least in adults diagnosed with type 2 diabetes, the explanation might be that the person already had undiagnosed diabetes or the hyperglycemia may be stress-induced and temporary.
The German Diabetes Center is funded by the German Federal Ministry of Health and the Ministry of Culture and Science of the State of North Rhine-Westphalia. Dr. Rathmann has reported receiving consulting fees for attending educational sessions or advisory boards for AstraZeneca, Boehringer Ingelheim, and Novo Nordisk and institutional research grants from Novo Nordisk outside of the topic of the current work.

Hands trained for surgery now on machine gun: Kyiv oncologist
The pediatric oncology unit in Kyiv’s National Cancer Institute is empty, with all the children evacuated to safer hospitals in Western Ukraine or further, making it a good place to talk on Zoom.
Against a backdrop of colorful animals painted on the wall, Oleksandr Stakhovskyi, MD, PhD, speaks optimistically about the future of his city, his country, and even his patients, despite acknowledging that his surgical hands are now trained to use a machine gun.
“It’s not as bad as last week,” he laughs, explaining that residents of Kyiv are more relaxed now, despite the air raid sirens, because the city’s anti-missile system has thus far kept them safe.
Even still, missiles have continued hitting civilian residences and Dr. Stakhovskyi, a urologic-oncology surgeon, has evacuated his wife and children out of the country, as have 70% of his colleagues. But for those who stayed in Kyiv, there is a strong resolve.
“People working in IT, in law, in other professions — they just took the guns and stayed in Kyiv,” he said in an interview. “They are just civilians, armed, trying to protect and fortify Kyiv — to make it unbreakable.”
Dr. Stakhovskyi doesn’t have a background in the military, but he now knows how to use a machine gun. “I am a super-specialized oncologist, [but] I realize if I leave right now it will give the Russians momentum to come in. The longer it takes, the weaker the opponent army will become, and we are more and more optimistic,” he said.
In Kyiv, Dr. Stakhovskyi is working half the time at the cancer hospital and the other half at the nearby military hospital, but he said so far war casualties are minimal within the city, and even the flow of patients with cancer has reduced.
“I had my surgeries planned up until the end of March, but when the war started, they were all postponed,” he said. Emergency cancer surgeries have continued, and now there is talk of resuming some others. “We will stratify patients into categories based on need,” he said. “For those patients whose surgery can basically stop the disease and they don’t need neoadjuvant chemo, we’ll probably be doing those.”
Medical oncology clinics have also resumed, said Dr. Stakhovskyi, but the volume of patients is low, because many have left the city. An estimated 3.3 million people have left Ukraine since the Russian invasion on February 24.
Across the country, in Lviv near the Polish border, another surgical oncologist tells a different story. Andriy Hrynkiv, MD, from Lviv Regional Cancer Center, says his hospital has seen a dramatic increase in patients, displaced internally from areas where the medical infrastructure has collapsed.
“Russian forces have destroyed more than 117 hospitals, 43 ambulances have been shot at, 6 doctors have been killed, and 13 wounded,” Dr. Hrynkiv said. In the city of Mariupol, “doctors and patients have been taken hostage,” he said, used by Russian forces as a human shield. In Kharkiv, with approximately 1.5 million residents, the only oncologic hospital has been destroyed.
There is a shortage and instability of medical supplies including all iodine-containing medications that citizens are stocking up on in the face of a potential nuclear attack, he said.
Dr. Hrynkiv was speaking on a webcast organized by the American Society of Clinical Oncology (ASCO) and European Cancer Organisation (ECO).
The two organizations are collaborating with each other and the World Health Organization to create a special network that is aiming to connect professionals, academic and clinical centers, and patient groups.
Additionally, the Ukranian Society of Clinical Oncology (USCO), cofounded by Dr. Stakhovskyi, is trying to keep patients connected with nongovernment organizations.
“These patient organizations moved west when the war started, but they still use us to help them make contact with foreign doctors,” he said. “We have tried to centralize this process but it’s very difficult because patients and organizations are also calling doctors and centers directly looking for treatment options.”
He says USCO is also coordinating the distribution of a donation of immunotherapy pembrolizumab (Keytruda) from pharmaceutical company Merck Sharp & Dohme. “It’s a huge influx of this drug,” he says. “They’ve promised something like 2,000 doses to cover 230 patients for 3 months at least. Usually this is not an easy drug to access for people in Ukraine because it’s really expensive.”
Dr. Stakhovskyi said the optimism he feels is fueled by the support that Ukrainians feel from the rest of the world.
“We see the reaction of our international colleagues. It is so impressive and touching — lots of my ex-professors are texting me and sending me messages from all over the place, from Germany, from Canada, from France, from the United States,” he said. “And if we can be optimistic for ourselves, definitely that translates to our patients.”

He says USCO is also coordinating the distribution of a donation of immunotherapy pembrolizumab (Keytruda) from pharmaceutical company Merck Sharp & Dohme. “It’s a huge influx of this drug,” he says. “They’ve promised something like 2,000 doses to cover 230 patients for 3 months at least. Usually this is not an easy drug to access for people in Ukraine because it’s really expensive.”
Dr. Stakhovskyi said the optimism he feels is fueled by the support that Ukrainians feel from the rest of the world.
“We see the reaction of our international colleagues. It is so impressive and touching — lots of my ex-professors are texting me and sending me messages from all over the place, from Germany, from Canada, from France, from the United States,” he said. “And if we can be optimistic for ourselves, definitely that translates to our patients.”

The pediatric oncology unit in Kyiv’s National Cancer Institute is empty, with all the children evacuated to safer hospitals in Western Ukraine or further, making it a good place to talk on Zoom.
Against a backdrop of colorful animals painted on the wall, Oleksandr Stakhovskyi, MD, PhD, speaks optimistically about the future of his city, his country, and even his patients, despite acknowledging that his surgical hands are now trained to use a machine gun.
“It’s not as bad as last week,” he laughs, explaining that residents of Kyiv are more relaxed now, despite the air raid sirens, because the city’s anti-missile system has thus far kept them safe.
Even still, missiles have continued hitting civilian residences and Dr. Stakhovskyi, a urologic-oncology surgeon, has evacuated his wife and children out of the country, as have 70% of his colleagues. But for those who stayed in Kyiv, there is a strong resolve.
“People working in IT, in law, in other professions — they just took the guns and stayed in Kyiv,” he said in an interview. “They are just civilians, armed, trying to protect and fortify Kyiv — to make it unbreakable.”
Dr. Stakhovskyi doesn’t have a background in the military, but he now knows how to use a machine gun. “I am a super-specialized oncologist, [but] I realize if I leave right now it will give the Russians momentum to come in. The longer it takes, the weaker the opponent army will become, and we are more and more optimistic,” he said.
In Kyiv, Dr. Stakhovskyi is working half the time at the cancer hospital and the other half at the nearby military hospital, but he said so far war casualties are minimal within the city, and even the flow of patients with cancer has reduced.
“I had my surgeries planned up until the end of March, but when the war started, they were all postponed,” he said. Emergency cancer surgeries have continued, and now there is talk of resuming some others. “We will stratify patients into categories based on need,” he said. “For those patients whose surgery can basically stop the disease and they don’t need neoadjuvant chemo, we’ll probably be doing those.”
Medical oncology clinics have also resumed, said Dr. Stakhovskyi, but the volume of patients is low, because many have left the city. An estimated 3.3 million people have left Ukraine since the Russian invasion on February 24.
Across the country, in Lviv near the Polish border, another surgical oncologist tells a different story. Andriy Hrynkiv, MD, from Lviv Regional Cancer Center, says his hospital has seen a dramatic increase in patients, displaced internally from areas where the medical infrastructure has collapsed.
“Russian forces have destroyed more than 117 hospitals, 43 ambulances have been shot at, 6 doctors have been killed, and 13 wounded,” Dr. Hrynkiv said. In the city of Mariupol, “doctors and patients have been taken hostage,” he said, used by Russian forces as a human shield. In Kharkiv, with approximately 1.5 million residents, the only oncologic hospital has been destroyed.
There is a shortage and instability of medical supplies including all iodine-containing medications that citizens are stocking up on in the face of a potential nuclear attack, he said.
Dr. Hrynkiv was speaking on a webcast organized by the American Society of Clinical Oncology (ASCO) and European Cancer Organisation (ECO).
The two organizations are collaborating with each other and the World Health Organization to create a special network that is aiming to connect professionals, academic and clinical centers, and patient groups.
Additionally, the Ukranian Society of Clinical Oncology (USCO), cofounded by Dr. Stakhovskyi, is trying to keep patients connected with nongovernment organizations.
“These patient organizations moved west when the war started, but they still use us to help them make contact with foreign doctors,” he said. “We have tried to centralize this process but it’s very difficult because patients and organizations are also calling doctors and centers directly looking for treatment options.”
He says USCO is also coordinating the distribution of a donation of immunotherapy pembrolizumab (Keytruda) from pharmaceutical company Merck Sharp & Dohme. “It’s a huge influx of this drug,” he says. “They’ve promised something like 2,000 doses to cover 230 patients for 3 months at least.

Yes, Russian docs should be shut out of medical associations, says ethicist
This transcript has been edited for clarity.
Hi. I’m Art Caplan. I’m at the division of medical ethics at the NYU Grossman School of Medicine.
There are many difficult moral issues that are being fueled by the terrible war that Russia is waging against Ukraine. I think there is no way to justify anything that the Russians are doing. Ukraine did not do anything to violate Russian integrity, Russian territorial integrity, or anything by way of being aggressive toward Russia.
Russia decided at some point it wanted the Ukraine back. Putin has a dream, as the long-standing leader of Russia, to restore the Soviet empire, and Ukraine is top of the list of the places that he wants back for a variety of reasons.
We’re not here to debate the merits and demerits of this terrible act of war.
The European Society of Cardiology made a decision very recently to drop, as members, both Russia and Belarus, Russia’s ally in this aggressive war against Ukraine. They basically found it intolerable to have business as usual with these subsidiary cardiology societies as part of the ongoing activities of the European group.
The sole goal of this overarching European group is to reduce the health burden of cardiovascular disease. It doesn’t have political goals. It doesn’t have much to say about anything other than, “Let’s get evidence-based medicine used to try and prevent heart disease or treat heart disease.” So there’s noble intent.
Many of its members asked, “What are we doing in politics? Why are we punishing Russian and Belarussian cardiologists, acting as if somehow they are responsible for what the Russian army is doing or for what Putin has decided to do? Why are we acting against them? They are just trying to fight heart disease. That’s a legitimate goal for any doctor, public health official, or scientist.” They didn’t see, as members, why this exclusion had taken place.
I believe the exclusion is appropriate and some of the membership, obviously, in the European Society of Cardiology, agrees. It’s not because they’re holding doctors or scientists directly accountable for Putin’s war crimes, ethnic cleansing assault, or bombing and shelling of hospitals, maternity hospitals, and civilians.
They understand that these scientists and doctors have little to do with such things, but we are in a new form of warfare, and that warfare is basically economic and sociologic: turning Russia, as an inexcusably aggressive state, into a pariah.
The reason to break the ties is that that is the way to bring pressure upon Putin and his kleptocratic, oligarchic advisers to stop the attack, to try and bring down their economy, to say, “Business is not going to go on as usual. You will be excluded from normal scientific and medical commerce. We’re not going to be holding conferences or exchanging ideas,” and in my view, extending it to say, “We’re not taking your papers, we’re not publishing anything you do. We’re not even having you speak at our meetings until this war, this aggressive invasion, and these war crimes come to a halt.”
There is actually a basis for this action. It isn’t in the organization’s own bylaws, which as I said, are very simple — reduce cardiovascular disease burden — but they are a member of a broader group, the Biomedical Alliance in Europe, which does have a very explicit code of ethics.
I’m going to read you a little bit from that code. It says healthcare organizations should uphold and promote equality, diversity and inclusion, accountability, transparency, and equality. They also say that all members, including the European Society of Cardiology, should be committed both to the Declaration of Helsinki, a fundamental medical ethics document, and the Declaration of Geneva. These rules refer to the highest respect of human beings, responsible resource allocation, and preservation of the environment, among other things.
What the organization is doing is consistent with the code of ethics that the broader organization of all the medical societies of Europe say that these individual groups should be doing. You can’t collaborate with war criminals. You can’t act as if business as usual is going on. That’s not inclusive. That’s not respect for diversity.
I think the Ukrainian medical societies of cardiology and other specialties would find it grimly ironic to say that keeping Russian and Belarus members makes sense, given what’s going on in their country and what is happening to them. They’re under attack. They’re being killed. Their healthcare institutions are being indiscriminately shelled and bombed.
It’s very hard — and I understand that — to say we’re going to punish scientists. We’re going to, perhaps, even cause public health problems in Russia because we’re not going to collaborate right now with doctors and scientists in cardiology or any other medical specialty. I think it’s what has to be done.
We’re in a new era of trying to combat what is basically organized, international ethnic terrorism, complete with war crimes. We fight financially. We fight by isolating. We fight by excluding. It’s painful. It’s difficult. It’s somewhat unfair to individuals.
Only through that kind of pain are we going to get the kind of pressure that will achieve justice. I think that is a goal that we have to commend the European Society of Cardiology for honoring.
