Building an AI Army of Digital Twins to Fight Cancer
A patient has cancer. It’s decision time.
Clinician and patient alike face, really, the ultimate challenge when making those decisions. They have to consider the patient’s individual circumstances, available treatment options, potential side effects, relevant clinical data such as the patient’s genetic profile and cancer specifics, and more.
“That’s a lot of information to hold,” said Uzma Asghar, PhD, MRCP, a British consultant medical oncologist at The Royal Marsden Hospital and a chief scientific officer at Concr LTD.
What if there were a way to test — quickly and accurately — all the potential paths forward?
That’s the goal of digital twins.
“What the [digital twin] model can do for the clinician is to hold all that information and process it really quickly, within a couple of minutes,” Asghar noted.
A digital twin is more than just a computer model or simulation because it copies a real-world person and relies on real-world data. Some digital twin programs also integrate new information as it becomes available. This technology holds promise for personalized medicine, drug discovery, developing screening strategies, and better understanding diseases.
How to Deliver a Twin
To create a digital twin, experts develop a computer model with data to hone its expertise in an area of medicine, such as cancer types and treatments. Then “you train the model on information it’s seen, and then introduce a patient and patient’s information,” said Asghar.
Asghar is currently working with colleagues to develop digital twins that could eventually help solve the aforementioned cancer scenario — a doctor and patient decide the best course of cancer treatment. But their applications are manifold, particularly in clinical research.
Digital twins often include a machine learning component, which would fall under the umbrella term of AI, said Asghar, but it’s not like ChatGPT or other generative AI modules many people are now familiar with.
“The difference here is the model is not there to replace the clinician or to replace clinical trials,” Asghar noted. Instead, digital twins help make decisions faster in a way that can be more affordable.
Digital Twins to Predict Cancer Outcomes
Asghar is currently involved in UK clinical trials enrolling patients with cancer to test the accuracy of digital twin programs.
At this point, these studies do not yet use digital twins to guide the course of treatment, which is something they hope to do eventually. For now, they are still at the validation phase — the digital twin program makes predictions about the treatments and then the researchers later evaluate how accurate the predictions turned out to be based on real information from the enrolled patients.
Their current model gives predictions for RECIST (response evaluation criteria in solid tumor), treatment response, and survival. In addition to collecting data from ongoing clinical trials, they’ve used retrospective data, such as from the Cancer Tumor Atlas, to test the model.
“We’ve clinically validated it now in over 9000 patients,” said Asghar, who noted that they are constantly testing it on new patients. Their data include 30 chemotherapies and 23 cancer types, but they are focusing on four: Triple-negative breast cancer, cancer of unknown primary, pancreatic cancer, and colorectal cancer.
“The reason for choosing those four cancer types is that they are aggressive, their response to chemotherapy isn’t as great, and the outcome for those patient populations, there’s significant room for improvement,” Asghar explained.
Currently, Asghar said, the model is around 80%-90% correct in predicting what the actual clinical outcomes turn out to be.
The final stage of their work, before it becomes widely available to clinicians, will be to integrate it into a clinical trial in which some clinicians use the model to make decisions about treatment vs some who don’t use the model. By studying patient outcomes in both groups, they will be able to determine the value of the digital twin program they created.
What Else Can a Twin Do? A Lot
While a model that helps clinicians make decisions about cancer treatments may be among the first digital twin programs that become widely available, there are many other kinds of digital twins in the works.
For example, a digital twin could be used as a benchmark for a patient to determine how their cancer might have progressed without treatment. Say a patient’s tumor grew during treatment, it might seem like the treatment failed, but a digital twin might show that if left untreated, the tumor would have grown five times as fast, said Paul Macklin, PhD, professor in the Department of Intelligent Systems Engineering at Indiana University Bloomington.
Alternatively, if the virtual patient’s tumor is around the same size as the real patient’s tumor, “that means that treatment has lost its efficacy. It’s time to do something new,” said Macklin. And a digital twin could help with not only choosing a therapy but also choosing a dosing schedule, he noted.
The models can also be updated as new treatments come out, which could help clinicians virtually explore how they might affect a patient before having that patient switch treatments.
Digital twins could also assist in decision-making based on a patient’s priorities and real-life circumstances. “Maybe your priority is not necessarily to shrink this [tumor] at all costs ... maybe your priority is some mix of that and also quality of life,” Macklin said, referring to potential side effects. Or if someone lives 3 hours from the nearest cancer center, a digital twin could help determine whether less frequent treatments could still be effective.
And while much of the activity around digital twins in biomedical research has been focused on cancer, Asghar said the technology has the potential to be applied to other diseases as well. A digital twin for cardiovascular disease could help doctors choose the best treatment. It could also integrate new information from a smartwatch or glucose monitor to make better predictions and help doctors adjust the treatment plan.
Faster, More Effective Research With Twins
Because digital twin programs can quickly analyze large datasets, they can also make real-world studies more effective and efficient.
Though digital twins would not fully replace real clinical trials, they could help run through preliminary scenarios before starting a full clinical trial, which would “save everybody some money, time and pain and risk,” said Macklin.
It’s also possible to use digital twins to design better screening strategies for early cancer detection and monitoring, said Ioannis Zervantonakis, PhD, a bioengineering professor at the University of Pittsburgh.
Zervantonakis is tapping digital twin technology for research that homes in on understanding tumors. In this case, the digital twin is a virtual representation of a real tumor, complete with its complex network of cells and the surrounding tissue.
Zervantonakis’ lab is using the technology to study cell-cell interactions in the tumor microenvironment, with a focus on human epidermal growth factor receptor 2–targeted therapy resistance in breast cancer. The digital twin they developed will simulate tumor growth, predict drug response, analyze cellular interactions, and optimize treatment strategies.
The Long Push Forward
One big hurdle to making digital twins more widely available is that regulation for the technology is still in progress.
“We’re developing the technology, and what’s also happening is the regulatory framework is being developed in parallel. So we’re almost developing things blindly on the basis that we think this is what the regulators would want,” explained Asghar.
“It’s really important that these technologies are regulated properly, just like drugs, and that’s what we’re pushing and advocating for,” said Asghar, noting that people need to know that like drugs, a digital twin has strengths and limitations.
And while a digital twin can be a cost-saving approach in the long run, it does require funding to get a program built, and finding funds can be difficult because not everyone knows about the technology. More funding means more trials.
With more data, Asghar is hopeful that within a few years, a digital twin model could be available for clinicians to use to help inform treatment decisions. This could lead to more effective treatments and, ultimately, better patient outcomes.

Doctors Caution Over Weight Loss Drug Link to Nurse’s Death
Doctors have urged caution in linking the weight loss drug tirzepatide to the death of a 58-year-old nurse from Scotland.
Susan McGowan, from North Lanarkshire, took two low-dose injections of tirzepatide (Mounjaro) over the course of about 2 weeks before her death in September.
BBC News reported that multiple organ failure, septic shock, and pancreatitis were listed on her death certificate as the immediate cause of death, with “the use of prescribed tirzepatide” recorded as a contributing factor.
McGowan worked as a nurse at University Hospital Monklands in Airdrie. A family member said that, apart from carrying a “bit of extra weight,” she had been otherwise healthy and was not taking any other medication.
It is understood that McGowan had sought medical advice before purchasing a prescription for tirzepatide through a registered UK pharmacy. However, days after administering a second injection, she went to A&E at Monklands with severe stomach pain and sickness. She died on September 4.
Expert Insights
Commenting to the Science Media Centre (SMC), Amanda Adler, MD, PhD, professor of diabetic medicine and health policy at the University of Oxford, described the nurse’s death as “sad” but said that “whether or not it was related to tirzepatide may be difficult to prove.” While tirzepatide can be associated with uncommon problems such as acute pancreatitis, “one can develop acute pancreatitis for many other reasons as well,” she said.
Naveed Sattar, MD, PhD, professor of metabolic medicine at the University of Glasgow, noted that data from multiple trials of tirzepatide, involving around 10,000 people living with diabetes or obesity, “do not suggest a higher risk of pancreatitis.” Furthermore, “the data seem to show acceptable safety thus far and a range of benefits including sizable average weight loss (near 20%), strong diabetes prevention, and considerable benefits in people living with sleep apnea,” he told the SMC.
Approved Based on Extensive Assessment
Tirzepatide, a GLP-1 receptor agonist, was approved for use as a weight loss aid in the United Kingdom in November last year by the Medicines and Healthcare products Regulatory Agency (MHRA). It lists nausea, diarrhea, and vomiting as the most common side effects, as well as hypoglycemia for patients with diabetes.
Available figures under the Yellow Card scheme up to 19 May 2024 show that there were 208 adverse drug reactions reported about tirzepatide this year, including 31 serious reactions and one suspected death of a man in his 60s.
In a statement, a spokesperson for the drug’s manufacturer, Eli Lilly, said, “Patient safety is Lilly’s top priority. We are committed to continually monitoring, evaluating, and reporting safety information for all Lilly medicines.
“Mounjaro (tirzepatide) was approved based on extensive assessment of the benefits and risks of the medicine, and we provide information about the benefits and risks of all our medicines to regulators around the world to ensure the latest information is available for prescribers. If anyone is experiencing side effects when taking any Lilly medicine, they should talk to their doctor or other healthcare professional.”
In October, the NHS submitted plans to the National Institute for Health and Care Excellence (NICE) for a phased rollout of tirzepatide in England that would initially prioritize patients with the greatest clinical need. The first phase would see the drug available to people with a body mass index of more than 40 kg/m2 who also suffer from at least three of the main weight-related health problems: hypertension, dyslipidemia, obstructive sleep apnea, and cardiovascular disease.
“Our sincere sympathies are with the family of individual concerned,” said Alison Cave, MHRA Chief Safety Officer.
“Patient safety is our top priority and no medicine would be approved unless it met our expected standards of safety, quality, and effectiveness. Our role is to continually monitor the safety of medicines during their use, such as GLP-1 RAs. We have robust, safety monitoring and surveillance systems in place for all healthcare products.
“New medicines, such as tirzepatide, are more intensively monitored to ensure that any new safety issues are identified promptly. We strongly encourage the reporting of all suspected reactions to newer medicines, which are denoted by an inverted Black Triangle symbol.
“On the basis of the current evidence the benefits of GLP-1 RAs outweigh the potential risks when used for the licensed indications. The decision to start, continue, or stop treatments should be made jointly by patients and their doctor, based on full consideration of the benefits and risks.”
She encouraged patients and healthcare professionals to continue reporting suspected side effects to GLP-1 RAs, such as tirzepatide, through the Yellow Card Scheme. “When a safety issue is confirmed, we always act promptly to inform patients and healthcare professionals and take appropriate steps to mitigate any identified risk.”
The Department of Health and Social Care declined to comment.
Adler disclosed being involved as an unpaid investigator on an Eli Lilly–funded trial for a different drug. Sattar has disclosed no relevant financial relationships.

If anyone is experiencing side effects when taking any Lilly medicine, they should talk to their doctor or other healthcare professional.”
In October, the NHS submitted plans to the National Institute for Health and Care Excellence (NICE) for a phased rollout of tirzepatide in England that would initially prioritize patients with the greatest clinical need. The first phase would see the drug available to people with a body mass index of more than 40 kg/m2 who also suffer from at least three of the main weight-related health problems: hypertension, dyslipidemia, obstructive sleep apnea, and cardiovascular disease.
“Our sincere sympathies are with the family of individual concerned,” said Alison Cave, MHRA Chief Safety Officer.
“Patient safety is our top priority and no medicine would be approved unless it met our expected standards of safety, quality, and effectiveness. Our role is to continually monitor the safety of medicines during their use, such as GLP-1 RAs. We have robust, safety monitoring and surveillance systems in place for all healthcare products.
“New medicines, such as tirzepatide, are more intensively monitored to ensure that any new safety issues are identified promptly. We strongly encourage the reporting of all suspected reactions to newer medicines, which are denoted by an inverted Black Triangle symbol.
“On the basis of the current evidence the benefits of GLP-1 RAs outweigh the potential risks when used for the licensed indications. The decision to start, continue, or stop treatments should be made jointly by patients and their doctor, based on full consideration of the benefits and risks.”
She encouraged patients and healthcare professionals to continue reporting suspected side effects to GLP-1 RAs, such as tirzepatide, through the Yellow Card Scheme. “When a safety issue is confirmed, we always act promptly to inform patients and healthcare professionals and take appropriate steps to mitigate any identified risk.”
The Department of Health and Social Care declined to comment.
Adler disclosed being involved as an unpaid investigator on an Eli Lilly–funded trial for a different drug. Sattar has disclosed no relevant financial relationships.

Is Acute Kidney Injury Really a Single Disease?
The search for a better biomarker than creatine for acute kidney injury (AKI) has been “long and elusive.” However, could researchers be on the right path now?
“The thinking is moving away from trying to find one biomarker that can be used for different types of kidney injury to a recognition that AKI is not just a single disease that a patient has or doesn’t have,” Rob D. Nerenz, PhD, an associate professor in the Department of Pathology and Laboratory Medicine at the Medical College of Wisconsin, Milwaukee, told this news organization. “It’s lots of different diseases that all affect the kidney in different ways.”
AKI is actually a “loose collection” of hepatorenal, cardiorenal, nephrotoxic, and sepsis-associated syndromes, as well as acute interstitial nephritis (AIN), he said. “So the question is not: ‘Is AKI present — yes or no?’ It’s: ‘What kind of AKI is present, and how do I treat it?’ ”
‘Mediocre Markers’
AKI affects about 10%-30% of hospitalized patients, according to Nerenz. It’s associated with an increased risk for adverse outcomes, including post-AKI chronic kidney disease and a mortality rate of approximately 24%.
Currently, AKI is defined by a rapid increase in serum creatinine, a decrease in urine output, or both.
“Those are mediocre markers,” Nerenz said, as serum creatinine is not very sensitive to acute change, and the increase is often detected after the therapeutic window of intervention has passed. In addition, “it only tells us that the kidneys are unhappy; it doesn’t say anything about the cause.”
Urine output is limited as a marker because many conditions affect it. “If you’re dehydrated, urine output is going to decrease,” he said. “And in some forms of AKI, urine output actually goes up.”
What’s needed, he said, is a more sensitive biomarker that’s detectable within a shorter timeframe of 2-6 hours following injury.
“Right now, we’re looking at 48 hours before a change becomes apparent, and that’s just too long. Plus, it should be kidney specific. One of the major limitations of the biomarkers that have been evaluated to this point is that, yes, they’re released by the kidney, but they’re also released by other tissue types within the body, and that hinders their effectiveness as a marker.”
Neutrophil Gelatinase-Associated Lipocalin (NGAL)
Although research on better biomarkers is ongoing, “there’s also a recognition that some of the protein markers that have been around for a while, if used appropriately, can provide value,” Nerenz said. These include, among others, NGAL.
NGAL works well in pediatric patients without other comorbidities, but it has been less useful in adult patients because it is also released by other cell types. However, recent research suggests it shows promise in patients with both cirrhosis and AKI.
There are three main causes of AKI in cirrhosis, Nerenz explained. The first is prerenal and can be primarily addressed through rehydration.
“When these patients come in, clinicians won’t do anything right away other than provide fluids. If creatinine improves over the 48-hour period of fluid replenishment, then the patient is sent home because there really isn’t extensive damage to the kidneys.”
If improvement isn’t seen after those 48 hours, then it could be one of two things: Hepatorenal syndrome or acute tubular necrosis. Patients with hepatorenal syndrome are candidates for terlipressin, which the Food and Drug Administration (FDA) approved for this indication in 2022 after it displayed notable efficacy in a double-blind study.
“You don’t want to give terlipressin to just anybody because if the issue is not a diminished blood supply to the kidney, it’s not going to help, and comes with some serious side effects, such as respiratory failure,” Nerenz explained. “Having a biomarker that can distinguish between hepatorenal syndrome and acute tubular necrosis really helps clinicians confidently identify which patients are good candidates for this drug. Right now, we’re flying blind to a certain extent, basically using clinical intuition.”
Currently, the determination of NGAL is FDA cleared only for pediatric use. One way hospitals have dealt with that is by making the test in their own labs, using appropriate reagents, validation, and so forth. These tests are then safe for use in adults but haven’t gone through the FDA approval process.
However, the FDA’s recent announcement stating that the agency should oversee lab-developed tests has made this situation unclear, Nerenz said.
“At this point, we don’t know if there’s still an opportunity to take the NGAL test (or any other cleared biomarker) and validate it for use in a different patient population. Many hospital labs simply don’t have the resources to take these tests through the whole FDA approval process.”
A New Biomarker for AIN?
Meanwhile, research is also moving forward on a better biomarker for AIN, which is also under the AKI umbrella.
“It’s important to diagnose AIN because it has a very specific treatment,” Dennis G. Moledina, MD, PhD, Yale School of Medicine in New Haven, Connecticut, told this news organization.
“AIN is caused by a bunch of different medications, such as proton pump inhibitors, cancer drugs, nonsteroidal anti-inflammatory drugs, and antibiotics, so when someone has this condition, you have to stop potentially life-saving medications and give unnecessary and potentially toxic immunosuppressive drugs, like prednisone,” he said. “If you get the diagnosis wrong, you’re stopping vital drugs and giving immunosuppression for no reason. And if you miss the diagnosis, AIN can lead to permanent chronic kidney disease.”
“Right now, the only way to diagnose AIN is to do a kidney biopsy, which is risky because it can often lead to significant bleeding,” he said. “Some people can’t undergo a biopsy because they’re on medications that increase the risk of bleeding, and they can’t be stopped.”
Furthermore, he noted, “the longer a patient takes a drug that’s causing AIN without getting a diagnosis, the less the chances of recovery because the longer you let this kidney inflammation go on, the more fibrosis and permanent damage develops. So it is important to diagnose it as early as possible, and that’s again why we have a real need for a noninvasive biomarker that can be tested rapidly.”
Moledina and colleagues have been working on identifying a suitable biomarker for close to 10 years, the latest example of which is their 2023 study validating urinary CXCL9 as just such a marker.
“We’re most excited about CXCL9 because it’s already used to diagnose some other diseases in plasma,” Moledina said. “We think that we can convince labs to test it in urine.”
In an accompanying editorial, Mark Canney, PhD, and colleagues at the University of Ottawa and The Ottawa Hospital in Ontario, Canada, wrote that the CXCL9 study findings “are exciting because they provide a road map of where diagnostics can get to for this common, yet poorly identified and treated, cause of kidney damage. The need for a different approach can be readily identified from the fact that clinicians’ gestalt for diagnosing AIN was almost tantamount to tossing a coin (AUC, 0.57). CXCL9 alone outperformed not only the clinician’s prebiopsy suspicion but also an existing diagnostic model and other candidate biomarkers both in the discovery and external validation cohorts.”
Like NGAL, CXCL9 will have to go through the FDA approval process before it can be used for AIN. Therefore, it may be a few years before it can become routinely available, Moledina said.
Nevertheless, Nerenz added, “I think the next steps for AKI are probably continuing on this path of context-dependent, selective biomarker use. I anticipate that we’ll see ongoing development in this space, just expanding to a wider variety of clinical scenarios.”
Nerenz declared receiving research funding from Abbott Labs for evaluation of an AKI biomarker. Moledina is a co-inventor on a pending patent, “Methods and Systems for Diagnosis of Acute Interstitial Nephritis”; a cofounder of the diagnostics company Predict AIN; and a consultant for Biohaven.

What Matters Most for Young Patients With CRC: Survey Highlights Top Concerns
“We tend to think of cancer as a disease of older populations, but it’s impacting younger people who are in important developmental stages of their lives,” said Samantha Savitch, MD, in a podcast from the American College of Surgeons (ACS) Clinical Congress 2024, where she presented her research.
In fact, since 1994, cases of young-onset CRC have increased by more than 50%, according to the National Cancer Institute.
“Our goal with the study was to better understand what young adults with colorectal cancer really care about, so that we can ensure that we’re properly addressing their needs as part of like comprehensive cancer care,” Savitch, with the University of Michigan, Ann Arbor, Michigan, explained.
The researchers interviewed a sample of 35 patients who were diagnosed with CRC before the age of 50 years. The researchers asked patients open-ended questions about the influence their CRC diagnosis had on their lives, the daily challenges they experienced, as well as concerns about the future.
Patients expressed the greatest concern about four areas of health and well-being: Physical health, mental health, family planning, and career.
For physical health, patients worried about incontinence, loss of vitality, and expenses related to healthcare. On the mental health front, patients expressed concern about the uncertainty surrounding long-term survival and anxiety about the timing of their diagnosis. Family planning was a key issue as well, with patients highlighting uncertainties about fertility after chemotherapy. On the career front, patients also noted concerns surrounding job security, challenges pursuing advanced degrees, and a reliance on benefits from employment.
These concerns were not gender-specific. Career, physical health, financial security, mental health, fertility, and family planning were equally important to men and women.
Savitch provided a sample of quotes from interviewees that illustrated their specific concerns in each category.
A 47-year-old man reflected on his physical health now that his rectum is gone. “I no longer have that feeling of sensation like in my cheeks; basically, the cheeks and the anus area is all dead,” he said. A 48-year-old woman discussed the havoc chemotherapy wrecked on her teeth. “I don’t want to get emotional, I just went to the dentist yesterday, and I just get so frustrated ... All these things to pay. I should be happy to be alive,” she said. But “I have so much money in my mouth.”
On the mental health front, a 34-year-old woman described the fear she felt about a cancer recurrence following the birth of her daughter. After a CT scan, she had to experience 2 weeks of limbo, thinking, “I have cancer again.” She had begun a journal dedicated to her daughter in case she had a recurrence and died. “I always think that I am going to die. I think about death every day.”
Reflecting on her future fertility, a 22-year-old woman recalled the uncertainty surrounding whether chemotherapy would affect her ability to have children. “I would get really nervous,” she said, “so I was like, ‘I will do the injections. I just want to save a few of my eggs just in case.’ ” A 33-year-old man opted not to freeze his sperm because “I didn’t know if I was going to live or die, I didn’t know anything ... I barely had any money. So, like, do I risk putting this money up to freeze something when I don’t even know if I am going to be here or not?”
On the career front, a 48-year-old man highlighted how his cancer completely changed his family’s life.”I went from being a provider for my family, making enough money to take care of my family, where my wife was staying home, to now not being able to work and her having to pick up little side jobs and stuff just to try to help make ends meet.”
“These aspects of cancer care are rarely discussed, so it is important to acknowledge that patients care about fertility and family planning, their career aspirations, building assets — all things they must put on hold because of their cancer diagnosis,” Savitch said in a news release.
“This goes beyond just colorectal cancer,” Savitch added. “There are a lot of patients experiencing similar challenges, so we need more research to better understand these issues in patients with colorectal cancer as well as other cancers and, ultimately, to restructure our comprehensive cancer programs to make sure we are treating the patient and not just the disease.”
Support for the study was provided by the Rogel Cancer Center at the University of Michigan. Savitch had no relevant disclosures.

“We tend to think of cancer as a disease of older populations, but it’s impacting younger people who are in important developmental stages of their lives,” said Samantha Savitch, MD, in a podcast from the American College of Surgeons (ACS) Clinical Congress 2024, where she presented her research.
In fact, since 1994, cases of young-onset CRC have increased by more than 50%, according to the National Cancer Institute.
“Our goal with the study was to better understand what young adults with colorectal cancer really care about, so that we can ensure that we’re properly addressing their needs as part of like comprehensive cancer care,” Savitch, with the University of Michigan, Ann Arbor, Michigan, explained.
The researchers interviewed a sample of 35 patients who were diagnosed with CRC before the age of 50 years. The researchers asked patients open-ended questions about the influence their CRC diagnosis had on their lives, the daily challenges they experienced, as well as concerns about the future.
Patients expressed the greatest concern about four areas of health and well-being: Physical health, mental health, family planning, and career.
For physical health, patients worried about incontinence, loss of vitality, and expenses related to healthcare. On the mental health front, patients expressed concern about the uncertainty surrounding long-term survival and anxiety about the timing of their diagnosis. Family planning was a key issue as well, with patients highlighting uncertainties about fertility after chemotherapy. On the career front, patients also noted concerns surrounding job security, challenges pursuing advanced degrees, and a reliance on benefits from employment.
These concerns were not gender-specific. Career, physical health, financial security, mental health, fertility, and family planning were equally important to men and women.
Savitch provided a sample of quotes from interviewees that illustrated their specific concerns in each category.
A 47-year-old man reflected on his physical health now that his rectum is gone. “I no longer have that feeling of sensation like in my cheeks; basically, the cheeks and the anus area is all dead,” he said. A 48-year-old woman discussed the havoc chemotherapy wrecked on her teeth. “I don’t want to get emotional, I just went to the dentist yesterday, and I just get so frustrated ... All these things to pay. I should be happy to be alive,” she said. But “I have so much money in my mouth.”
On the mental health front, a 34-year-old woman described the fear she felt about a cancer recurrence following the birth of her daughter. After a CT scan, she had to experience 2 weeks of limbo, thinking, “I have cancer again.” She had begun a journal dedicated to her daughter in case she had a recurrence and died. “I always think that I am going to die. I think about death every day.”
Reflecting on her future fertility, a 22-year-old woman recalled the uncertainty surrounding whether chemotherapy would affect her ability to have children. “I would get really nervous,” she said, “so I was like, ‘I will do the injections. I just want to save a few of my eggs just in case.’ ” A 33-year-old man opted not to freeze his sperm because “I didn’t know if I was going to live or die, I didn’t know anything ... I barely had any money. So, like, do I risk putting this money up to freeze something when I don’t even know if I am going to be here or not?”
On the career front, a 48-year-old man highlighted how his cancer completely changed his family’s life.”I went from being a provider for my family, making enough money to take care of my family, where my wife was staying home, to now not being able to work and her having to pick up little side jobs and stuff just to try to help make ends meet.”
“These aspects of cancer care are rarely discussed, so it is important to acknowledge that patients care about fertility and family planning, their career aspirations, building assets — all things they must put on hold because of their cancer diagnosis,” Savitch said in a news release.
“This goes beyond just colorectal cancer,” Savitch added. “There are a lot of patients experiencing similar challenges, so we need more research to better understand these issues in patients with colorectal cancer as well as other cancers and, ultimately, to restructure our comprehensive cancer programs to make sure we are treating the patient and not just the disease.”

FROM ACS 2024
Are GLP-1s the Newest Fertility Treatment?
First, there were “Ozempic babies.” Now, there is also Ozempic-before-baby.
Unplanned pregnancies are still regularly being reported among people using glucagon-like peptide 1 receptor agonist (GLP-1 RA) drugs, and now fertility specialists are increasingly incorporating the medicines into preconception care plans.
The specialists say their colleagues in other areas of medicine may have an opportunity, too, to talk about weight loss using these new drugs in terms of reproductive health. Motivation and compliance can transform when the goal isn’t simply weight loss but having children.
“We have this really special moment to help patients be healthier, in order to be healthier for their kids,” said Christina Boots, MD, MSci, an associate professor of reproductive endocrinology and infertility at Northwestern University’s Feinberg School of Medicine, Chicago. “And I think that’s also a very motivating moment. It may be hard to get up and go for a run to make my jeans fit better, but when I think about it in terms of, ‘this might someday help my future daughter,’ that is a whole different level of motivation.”
Here’s why, what to know about the current lengthy list of unknowns and risks, and some options for approaching the topic with patients.
What Fertility Docs Are Doing
While overweight and obesity are consistently linked to fertility and pregnancy outcomes, Boots predicts the biggest impact of GLP-1 weight loss for fertility among women will be a specific subset: Those who are not cycling regularly, such as those with polycystic ovary syndrome (PCOS).
“The women who are cycling regularly who have very unexplained infertility and no other comorbidities like high blood pressure or something else going on, I don’t think it’s going to help their fertility very much at all,” she said “It might, but I think there’s probably something else going on in her tubes or with her eggs or his sperm, but it has nothing to do with her metabolic health.
Women who aren’t cycling regularly will benefit, but those with truly unexplained fertility probably won’t, she said.
In their recent narrative review on treating obesity and fertility with GLP-1 RAs that appeared in Fertility and Sterility, Boots and co-author Alyse S. Goldberg, MD, an endocrinologist with the University of Toronto, Ontario, Canada, advocate for the use of GLP-1s as a go-to treatment for obesity as part of preconception care by reproductive endocrinologists, calling the drugs “the most effective, least invasive means of weight loss.”
The paper is timely and necessary because use of GLP-1s is only going to increase, Patricia Jimenez, MD, an associate professor of obstetrics and gynecology at Washington University School of Medicine in St. Louis, Missouri, said in an email to this news organization.
“GLP-1 RAs are becoming a larger part of my practice. More patients are either using them already or interested in using them,” said Jimenez, who is board certified in reproductive endocrinology, obstetrics and gynecology, and obesity medicine. “I specifically see patients to discuss this and do prescribe antiobesity medications, not only GLP-1 RAs. Often this is with people with PCOS who are not planning to conceive soon or patients willing to delay fertility treatment [by] 3-6 months.”
Treating obesity is also important for women who are seeking in vitro fertilization, Boots said, because many IVF clinics have a body mass index cutoff of 40 kg/m2.
Like Jimenez’s approach, Boots and Goldberg call for comprehensive obesity care beyond the use of medication, including nutritional counseling and mental health support. Those supports are important during the transition off of GLP-1 medications, which poses a risk for rapid weight regain. That’s even with the potential support of taking metformin, which Boots often prescribes as a bridge.
Semaglutide should be stopped at least 2 months prior to conception, and tirzepatide should be stopped 1 month prior to conception, according to the manufacturers. (Boots and Goldberg listed the Canadian label recommendation for stopping tirzepatide, noting there is no suggested timeline for stopping prior to conception on the US label.)
Numerous studies have shown rapid weight regain is common when stopping GLP-1s, which presents a unique set of risks for pregnant women including early pregnancy loss, gestational diabetes, preeclampsia, and nonelective cesarean delivery.
Weighing Risks, Benefits, and Unknowns
Early looks at small human data sets, mostly involving semaglutide and earlier short-acting GLP-1s, and their impact on the risk for birth defects are “reassuring,” Boots said.
“But birth defects are just one small aspect. There’s also metabolic health and things like that long-term. Understanding what it does to the growing baby and the proximity of that medication to that growing baby is really important to see, and can’t be answered with animal studies, not perfectly anyway,” Boots said.
There are no published reports, from clinical trials nor case collections, examining the use of tirzepatide among pregnant people.
“One of the most important questions we need to answer is the preconception safety of these medications, and that includes safety for men,” Joshua Halpern, MD, MS, an adjunct assistant professor of urology at Northwestern University’s Feinberg School of Medicine, and chief scientific officer for Posterity Health, said in an email to this news organization.
“For example, a recent study found that men who were taking metformin, another popular medication for diabetes, were more likely to have children with birth defects, compared with those who were not taking the medication,” Halpern said. “Further studies are needed to determine whether a similar effect might hold true for the GLP-1 agonists.”
Small early studies on sperm are encouraging, Halpern said, suggesting that GLP-1 use may be beneficial, but a better understanding of direct effects is needed.
Among women, there may be cases where continuing use of a GLP-1 during pregnancy may offer benefits that outweigh risks, Boots suggested. Manufacturers have also created pregnancy exposure registries to measure the safety of their therapies during pregnancy.
“I have a group of patients whose sugars are so well controlled on these medications, but as soon as they come off, they get weight regain and their glucose is just so poorly controlled,” she said. “There may be a group of women where the benefits of glucose control outweigh the risks of being on the medication the whole pregnancy.”
The list of important unknowns also includes a need to examine how rapid weight loss may impact ovulation rates and spontaneous conception, as well as miscarriage rates, birth weight, and metabolic health of the child.
More detailed rebound weight gain data is coming next year, with additional analysis expected as well on birth weight and pregnancy outcomes, said Jacqueline Maya, MD, first author of the research abstract presented at this year’s American Diabetes Association conference that examined gestational weight gain among people with preexisting type 2 diabetes who were exposed to GLP-1s during pregnancy. The study included 47 exposed pregnancies (based on prescription records and electronic chart information) and compared gestational weight gain to 141 unexposed matched pregnancies. Among the exposed group, 62% exceeded recommended weight gain, compared with 41% in the unexposed group. On average, gestational weight gain in exposed pregnancies exceeded that among matched unexposed pregnancies by about 6 pounds.
The team is now working with an additional data set to examine exposed pregnancies among people with obesity, said Maya, an instructor of pediatrics at Mass General Hospital and Harvard School of Medicine. She is particularly interested in examining weight trajectories during pregnancy to see how they may affect fetal outcomes. Her team’s current project also will likely include analysis to examine other variables like postpartum weight gain and adiposity characteristics of the baby.
Maya said the team hopes to have more to report at the American Diabetes Association conference in June next year.
Offer the Conversation
Using a GLP-1 for weight loss takes time, usually around 1 year to reach a plateau. Boots encouraged nonfertility providers to ask patients of reproductive age about their family plans as an opening.
“I hope for all primary care doctors and gynecologists, that with any patient of reproductive age, you should be bringing this up, asking, ‘Have you thought about having kids? Are you thinking about it soon?’ And if they say they are sometime in the near future, then you can say, ‘Is it OK if I bring up your weight?’ And you should ask permission.”
If the patient declines, it’s OK to bring it up again at a future visit.
“People with obesity have often experienced negative weight bias that impacts their care,” Jimenez said. “Treat obesity as a disease, not a personal failing. Ask permission to discuss weight with the patient beforehand. If they say no, respect that answer. This goes a long way in developing a positive relationship, so they return for care and may be willing to discuss later.”
When patients are open to the conversation, Boots suggests not focusing on the potential for poor outcomes, and instead perhaps saying, “If you’re thinking about having a baby in 5 years, optimizing your health now will not only make your pregnancy healthier, but your child healthier long-term.”
Discussing contraception plans remains important. People starting semaglutide or tirzepatide should use contraception other than oral birth control for 4 weeks while starting the medicine and for 4 weeks after each dose increase.
Boots said that the contraception conversation is particularly important because many people have come to deeply believe that they are infertile and, thus, may perhaps think contraception advice doesn’t apply to them. Maya hypothesized that behavioral changes following weight loss may also be a pathway toward pregnancy.
“Pregnancy while on GLP-1 RAs does happen. I always have a discussion about this possibility and contraception. This can sometimes be challenging for people with infertility to consider,” Jimenez said. “Explaining the risks, benefits, and unknowns can help. As the [Fertility and Sterility] paper describes, the limited data available has not shown increased fetal or maternal complications. We need more high quality data to better understand the impact of exposure or use around the time of conception and during pregnancy.”
It’s also important to introduce the idea to patients that they may someday need to come off the medications, such as when they are ready to have children, and how important lifestyle and behavioral changes will be at that time, Maya said.
“We do know what the alternative is, and we do know what the risks of obesity are,” she said. “So, it’s a tug and pull. We’re not starting off with healthy. We’re starting off with a disease that is physically and emotionally very difficult for the patient, especially when it starts in childhood.”

Digital Danger: How Cyberattacks Put Patients at Risk
On September 27, 2024, UMC Health System in Lubbock, Texas, experienced an IT outage because of a cybersecurity incident that temporarily diverted patients to other healthcare facilities. So far, in 2024, there have been 386 cyberattacks on healthcare organizations. These high-impact ransomware attacks disrupt and delay patient care.
In recent years, many healthcare systems, including Scripps Health, Universal Health Services, Vastaamo, Sky Lakes, and the University of Vermont, have paid millions — even tens of millions — to recover data after a cyberattack or data breach. When healthcare systems come under cyber fire, the impact extends far past disrupting workflows and compromising data, patient safety can be also be compromised, vital information may be lost, and imaging and lab results can go missing or be held for ransom, making physicians’ job difficult or impossible.
In fact, cyberattacks on hospitals are far more common than you may realize. A new report issued by Ponemon and Proofpoint found that 92% of healthcare organizations have experienced a cyberattack in the past 12 months. Even more sobering is that about half of the organizations affected suffered disruptions in patient care.
Healthcare Systems = ‘Soft Targets’
Healthcare systems are a “soft target” for hackers for several reasons, pointed out Matthew Radolec, vice president, incident response and cloud operations at Varonis, a data security company. “One, they’re usually an amalgamation of many healthcare systems that are interconnected,” said Radolec. “A lot of hospitals are connected to other hospitals or connected to educational institutions, which means their computer vulnerabilities are shared ... and if they have an issue, it could very easily spread to your network.”
Another factor is the cost of securing data. “[With hospitals], they’ll say that a dollar spent on security is a dollar not spent on patient care,” said Radolec. “So the idea of investing in security is really tough from a budget standpoint…they’re choosing between a new MRI machine or better antivirus, backups, or data security.”
Because of the wealth of private data and healthcare information they maintain, hospitals are considered “high impact” for cybercriminals. Attackers know that if they get a foothold in a hospital, it’s more likely to pay — and pay quickly, Radolec told this news organization. Hospitals are also likely to have cyber insurance to help cover the cost of having their data stolen, encrypted, and ransomed.
The 2024 Microsoft Digital Defense Report also found that the bad actors are more sophisticated and better resourced and can challenge even the best cybersecurity. Improved defenses may not be good enough, and the sheer volume of attacks must be met with effective deterrence and government solutions that impose consequences for cybercriminals.
Vulnerable Users
Whether through a phishing email or text, password attack, or web attack, “the moment a ‘threat actor’ gets into your institution and gets credentials ... that’s the Nirvana state of a threat actor,” warned Ryan Witt, chair of the healthcare customer advisory board and vice president of Industry Solutions at Proofpoint, a cybersecurity platform. “They have those credentials and will go into deep reconnaissance mode. It often takes healthcare up to 6 months to even ascertain whether somebody’s actually in the network.” During that time, the hacker is learning how the institution works, what job functions matter, and how best to plan their attack.
“Attackers are getting in because they’re buying databases of usernames and passwords. And they’re trying them by the millions,” added Radolec. “For a sophisticated actor, all it takes is time and motivation. They have the skills. It’s just a matter of how persistent they want to be.”
Certain hospital staff are also more likely to be targeted by cyberhackers than others. “About 10% of a healthcare organization’s user base is much more vulnerable for all sorts of reasons — how they work, the value of their job title and job function, and therefore their access to systems,” said Witt.
High-profile staff are more likely to be targeted than those in lower-level positions; the so-called “CEO attack” is typical. However, staff in other hospital departments are also subject to cybercriminals, including hospice departments/hospice organizations and research arms of hospitals.
The Impact of Cyberattacks on Patients
Physicians and healthcare execs may have considered cybersecurity more of a compliance issue than a true threat to patients in the past. But this attitude is rapidly changing. “We are starting to see a very clear connection between a cyber event and how it can impact patient care and patient safety,” said Witt.
According to the Proofpoint report, cyber breaches can severely affect patient care. In 2024:
- 56% of respondents saw a delay in patient tests/procedures
- 53% experienced increased patient complications from medical procedures
- 52% noted a longer patient length of stay
- 44% saw an increase in patient transfers to other facilities
- 28% had an increase in mortality rate
What Hospitals and Physicians Can Do
Fortunately, hospitals can take measures to better protect their data and their patients. One strategy is segmenting networks to reduce the amount of data or systems one person or system can access. Educating staff about the dangers of phishing and spoofing emails also help protect organizations from ransomware attacks. Having staff avoid reusing passwords and updating logins and passwords frequently helps.
Most hospitals also need more robust security controls. Physicians and healthcare facilities must also embrace the cybersecurity controls found in other industries, said Witt. “Multifactor authentication is one of those things that can cause us frustration,” he said. “The controls can seem onerous, but they’re really valuable overall…and should become standard practice.”
Doctors can also prepare for a ransomware attack and protect patients by practicing some “old-school” medicine, like using paper systems and maintaining good patient notes — often, those notes are synced locally as well as offsite, so you’d be able to access them even during a data breach. “It’s smart to write prescriptions on pads sometimes,” said Radolec. “Don’t forget how to do those things because that will make you more resilient in the event of a ransomware attack.”
A Continuing Threat
Cyberattacks will continue. “When you look at the high likelihood [of success] and the soft target, you end up with ... a perfect storm,” said Radolec. “Hospitals have a lot of vulnerabilities. They have to keep operations going just to receive income, but also to deliver care to people.”
That means that the burden is on healthcare organizations — including physicians, nurses, staff, and C-level execs — to help keep the “security” in cybersecurity. “We are all part of the cybersecurity defense,” said Witt. Helping to maintain that defense has become a critical aspect of caring for patients.

Plastic Pollution’s Next Victim: The Human Urinary Tract
Although a 2019 World Health Organization (WHO) report concluded that microplastics in drinking water posed no risk to human health, accumulating evidence is beginning to challenge these findings.
Since plastics became widely used in the mid-20th century, they have evolved from a novel substance to an essential component in countless applications, with global production reaching 368 million tons in 2019 and expected to double by 2039. The production and degradation of plastics involve physical, chemical, and biological processes, leading to the formation of tiny fragments known as microplastics (MPs) and nanoplastics (NPs), which accumulate in the environment. Beyond the well-documented environmental harms of MPs and NPs, growing evidence of their presence within the human body raises concerns about their potential to trigger various harmful biological processes. Their detection in the urinary tract and their potential links to kidney and bladder diseases, as shown in animal studies, are particularly alarming.
Impacts Becoming Apparent
As the impact of plastic pollution becomes increasingly apparent, the need for standardized international definitions of MPs and NPs is pressing. Government publications reveal notable discrepancies between organizations in defining these fragmented plastics. The lack of consensus among regulatory bodies highlights the challenges in mitigating the environmental and health impacts of MPs and NPs. The International Organization for Standardization offers the most precise classification, defining MPs as solid, insoluble plastic particles ranging from 1 µm to 1 mm and NPs as particles smaller than 1 µm.
The intrusion of MPs and NPs into the human body, whether through inhalation, ingestion, or skin exposure (via wounds, hair follicles, or sweat glands), has been linked to harmful biological effects, including inflammation, alterations in cellular metabolism, physical cellular damage, and reduced cell viability.
Urinary Tract Plastics
The detection of MPs and NPs in the human urinary tract, combined with limited understanding of their effects, is a growing concern. An exploratory study published earlier this year aimed to systematically summarize the existing literature regarding the presence of MPs and NPs in the urinary tract and their potential consequences, guided by these research questions:
- What are the characteristics of the plastics detected in the human urinary tract?
- How are MPs and NPs defined in the current literature?
- What methodologies are used to explore the presence and effects of MPs and NPs?
- What are the pathophysiologic consequences of the presence of MPs and NPs in the human urinary tract?
For this study, the “urinary tract” included the kidneys, bladder, ureter, urethra, and urine. By focusing on the urinary tract, the study aimed to consolidate current understanding of MPs and NPs, raise awareness of this emerging issue, and lay the groundwork for further research that could contribute to public health policies and clinical practice guidelines.
The researchers conducted a scoping literature review following the recommendations of the JBI [formerly known as the Joanna Briggs Institute). They systematically searched five databases — PubMed, Scopus, CINAHL, Web of Science, and Embase — as well as gray literature sources.
Concerning Study Results
Eighteen articles were identified. The authors represent seven countries: Pakistan (n = 1), the Netherlands (n = 1), the US (n = 1), Taiwan (n = 1), Germany (n = 3), China (n = 5), and Italy (n = 6). Among these studies, six investigated and characterized the presence of MPs and NPs in the human urinary tract. MPs and NPs were detected in urine samples (n = 5), kidney cancer samples (n = 2), and bladder cancer samples (n = 1).
Additionally, 12 studies examined the effects of MPs and NPs on human urinary tract cell lines. Their findings suggest that MPs and NPs have cytotoxic effects, increase inflammation, reduce cell viability, and alter mitogen-activated protein kinase signaling pathways.
Raman spectroscopy was the primary method used to detect and characterize MPs and NPs in human samples (five out of six studies; 83%). Alternatively, pyrolysis-gas chromatography-mass spectrometry combined with direct laser infrared spectroscopy was used in one study.
Further Research Needed
This exploratory study underscores the urgent need for further research and policy development to address the challenges posed by microplastic contamination. It highlights the rapidly emerging threat of human urinary tract contamination by microplastics, questioning the WHO’s claim that microplastics pose no public health risk. The documented cytotoxic effects of microplastics, and their ability to induce inflammation, reduce cell viability, and disrupt signaling pathways, raise significant public health concerns related to bladder cancer, chronic kidney disease, chronic urinary infections, and incontinence.

On the Road to Care: Travel Nurses Still in Demand
Ashly Doran has worked at seven hospitals in four states since she graduated from nursing school in 2020. No, she isn’t job-hopping. Her travel nursing assignments have ranged from level 1 trauma center emergency rooms in big cities to small medical-surgical units in the suburbs. After each 13-week assignment, Doran packs up her belongings and her cats and moves to a new post.
“Travel nursing is so flexible,” she said. “I decide where I want to go and how much I want to make and start looking for travel contracts in that area.”
Nationwide nursing shortages have forced hospitals to hire travel nurses to fill staffing gaps. During the COVID-19 pandemic, the demand for travel nurses increased by 35%. While there is still a demand for nurses to fill short-term contracts, data show that demand has declined 42% between January and July 2022 and has continued the downward trend.
“What we’re seeing now is a shift…to a pre-pandemic market,” said Rachel Neill, RN, senior clinician advocate at Vivian Health. “Travel [nursing] is not going away — there will always be a need for hospital systems and facilities to fill gaps — but hospitals have shifted more into a traditional ... operational environment.”
Traveling a Different Path
For some registered nurses (RNs), short-term assignments offer opportunities to gain experience in different facilities or explore new locations before settling into permanent positions. Even experienced RNs embrace travel nursing for the flexible schedules and opportunities to take longer breaks between contracts.
Burnout and turnover among nurses are high, and flexible schedules, including controlling when to work, are essential to sustaining a clinical nursing career. In fact, 34% of nurses called travel nursing an “ideal option” for their lifestyle, with 14% viewing it as an option for career progression.
Travel nursing is especially appealing to Millennials and Generation Z, according to Brian Weirich, RN, chief nurse innovation officer at Bon Secours Mercy Health in Cincinnati, Ohio. In fact, the average age of a travel nurse is 35 compared with an average age of 52 for all RNs.
These are generations that are more focused on reducing school loan debt and gaining experience, not 401(k) and health insurance, he said in an interview. Pay is also a factor. The average pay for travel nurses was $2588 per month, compared with $1375 for permanent staff nurses.
During the pandemic, Weirich recalls groups of nurses resigning to take travel assignments together. The RNs picked desirable locations, accepted short-term assignments, and moved together, “making top dollar in locations they wanted to explore with their best friends.”
It’s been more than a decade since Kelly Spurlock traded a permanent nursing role in Lake Placid, Florida, for short-term nursing contracts in intensive care units in 20 states.
Spurlock works with a recruiter at Ingenovis Health to secure new contracts and considers travel assignments “working vacations.” In the process of exploring new places and meeting new people, Spurlock believes that travel nursing allows her to prioritize patient care.
“I can be at the bedside and be an advocate for my patient but also keep out of the spotlight for the political part of what we do,” she explained.
The Road Ahead
The appeal of travel nursing is taking new nursing assignments in different cities and earning higher salaries, but there are downsides, too. Travel nurses often receive fewer benefits than staff nurses and end up with less favorable assignments; their levels of dissatisfaction and burnout are also higher, and their sense of work-life balance is lower than staff nurses.
Most travel contracts last between 4 and 13 weeks. Hospitals often put policies and practices in place that limit the number of back-to-back contracts that traveling nurses can accept, which means that RNs can either convert to core staff or move on to new assignments once their contract term is up.
Weirich noted that some hospitals devote considerable effort to recruiting traveling nurses to full-time roles, adding, “There are active initiatives ... to make it such a good experience that they want to stay.”
On the flip side, contracts can be terminated without notice, leaving traveling nurses scrambling to find a new assignment and a new place to live on short notice.
“You’re there as long as the hospital needs you,” said Neill. “You could sign a 12- or 15-week contract, and their needs change a month in, and ... there are budget cuts, and they can’t pay salaries anymore, so they are laying off their nurses.”
Declining demand for travel nurses has made it harder to line up back-to-back contracts. Despite being available for work, Doran once waited 6 weeks to secure a new assignment and had to live off her savings.
Spurlock believes increased competition and declining wages — pay for travel nurses declined more than 9% from January 2023 to January 2024 — have made travel nursing less attractive.
“There has been such an influx of travel nurses ... because of COVID,” said Spurlock. “The rates have now come down [and] everybody’s fighting for jobs, and ... it’s very difficult to get a job that’s paying decent money.”
Despite the challenges, Spurlock continues learning new things from each assignment and hopes to work as a travel nurse until retirement. Doran has worked at hospitals in Washington, Oregon, California, and Wisconsin and would like to add Montana, Utah, and Nevada to the list. The goal: Continue accepting assignments in different cities and states until she finds the place where she wants to put down roots.
“Nursing is a great job, but it’s a hard job [and] it can take its toll at times,” Neill said. It’s important that nurses know their goals and values to be able to find a good fitting position. “And the beauty of it is that travel can be a great way to explore and add some flexibility.”

Ashly Doran has worked at seven hospitals in four states since she graduated from nursing school in 2020. No, she isn’t job-hopping. Her travel nursing assignments have ranged from level 1 trauma center emergency rooms in big cities to small medical-surgical units in the suburbs. After each 13-week assignment, Doran packs up her belongings and her cats and moves to a new post.
“Travel nursing is so flexible,” she said. “I decide where I want to go and how much I want to make and start looking for travel contracts in that area.”
Nationwide nursing shortages have forced hospitals to hire travel nurses to fill staffing gaps. During the COVID-19 pandemic, the demand for travel nurses increased by 35%. While there is still a demand for nurses to fill short-term contracts, data show that demand has declined 42% between January and July 2022 and has continued the downward trend.
“What we’re seeing now is a shift…to a pre-pandemic market,” said Rachel Neill, RN, senior clinician advocate at Vivian Health. “Travel [nursing] is not going away — there will always be a need for hospital systems and facilities to fill gaps — but hospitals have shifted more into a traditional ... operational environment.”
Traveling a Different Path
For some registered nurses (RNs), short-term assignments offer opportunities to gain experience in different facilities or explore new locations before settling into permanent positions. Even experienced RNs embrace travel nursing for the flexible schedules and opportunities to take longer breaks between contracts.

The Bad News Behind the Rise in Locum Tenens
I’ve worked locum tenens off and on since 1982. Flexible schedules allowed me to write several books, pursue a parallel career as a medical journalist, lead medical missions in the Philippines, and develop modest expertise as an underwater photographer.
But the recent rise in locum tenens practitioners signals trouble for medicine.
A Multibillion-Dollar Industry
Roughly 52,000 US doctors work locum tenens full or part time. In annual reports by CHG Healthcare, two thirds of healthcare facilities surveyed report using locums and more than half expect to maintain or increase their use in 2024.
Another measure of the industry’s growth is that membership of The National Association of Locum Tenens Organizations (NALTO), formed in 2001 to lead this fledgling industry, has doubled since 2019. Currently, NALTO has 148 member agencies.
Why Locums?
What used to be the preserve of older physicians transitioning to retirement is now becoming a career choice. According to the 2024 Survey of Locum Tenens Physicians and Advanced Practice Professionals by AMN Healthcare, 81% of respondents said they started taking locum tenens assignments immediately after finishing medical training or in mid-career. What entices doctors to move from place to place, repeatedly adapt to new facilities and electronic medical records, live in cheap hotels, and work without paid vacations, health insurance, or retirement benefits?
Supplemental income is one reason. But the elephant in the room is clearly burnout. Rates of burnout in practicing doctors and physicians-in-training have exceeded 50%. Burnout results in medical errors, malpractice suits, and increased healthcare costs.
A recent Doximity poll of 7590 physicians revealed that 63% would not want their children to pursue a medical career. And in a Medscape survey of 7000 physicians, a third of docs under 40 would not choose medicine again if they had a do-over. If a career in medicine brings high income and privileged status, why do so many physicians regret it and discourage their children from taking the same path?
Where Is Marcus Welby, MD?
Private practice is an endangered species that no one is trying to save. According to a 2022 AMA survey, 44% of physicians owned their practices compared with 76% of physicians in the 1980s. Even fewer younger physicians are choosing private practice. Among physicians under 45 years of age, only 32% owned their practices. Most physicians are now employees, not employers. They have lost control over their duties and work hours.
In 2022, barely 13% of physicians were in solo practice. The iconic Dr Marcus Welby of the 1970s TV series has transmuted from an idealized physician to an implausible figure. (My medical students have never heard of him.)
Hospitals and health systems have purchased many private medical groups. Private-equity companies own close to 1000 physician practices and staff up to 40% of emergency rooms. For these firms, profits are paramount.
Canary in a Coal Mine
Locum tenens offers physicians unprecedented flexibility where they work, when they work, and how much they work. It provides an escape from overwhelming and unsatisfying clinical practice. While some physicians have fled to nonclinical careers, locums physicians can practice medicine without the burdens of administration, hospital politics, and ever-increasing overhead.
The locum tenens paradox is that its successful growth indicates a deteriorating traditional healthcare model. Locum tenens is not the problem, but it’s also not the solution. At best, locums is a pair of crutches that helps the current system limp along.
Healthcare is increasingly controlled by those who prioritize profit, not patients. If physicians become nothing more than complicit cogs in a dysfunctional system, burnout will fester. The profession will fail to attract the best and the brightest, the doctor shortage will increase, and the quality of patient care will decline. Everyone will suffer.
It’s already happening.

Brews, Bubbles, & Booze: Stroke Risk and Patients’ Favorite Drinks
This research roundup reviews the latest findings, highlighting both promising insights and remaining uncertainties to help guide discussions with your patients.
Coffee and Tea: Good or Bad?
In the INTERSTROKE study, high coffee consumption (> 4 cups daily) was associated with an significantly increased risk for all strokes (odds ratio [OR], 1.37) or ischemic stroke (OR, 1.31), while low to moderate coffee had no link to increased stroke risk. In contrast, tea consumption was associated with lower odds of all stroke (OR, 0.81 for highest intake) or ischemic stroke (OR, 0.81).
In a recent UK Biobank study, consumption of coffee or tea was associated with reduced risk for stroke and dementia, with the biggest benefit associated with consuming both beverages.
Specifically, the investigators found that individuals who drank two to three cups of coffee and two to three cups of tea per day had a 30% decrease in incidence of stroke and a 28% lower risk for dementia versus those who did not.
A recent systematic review and dose-response meta-analysis showed that each daily cup increase in tea was associated with an average 4% reduced risk for stroke and a 2% reduced risk for cardiovascular disease (CVD) events.
The protective effect of coffee and tea on stroke risk may be driven, in part, by flavonoids, which have antioxidant and anti-inflammatory properties, as well as positive effects on vascular function.
“The advice to patients should be that coffee and tea may protect against stroke, but that sweetening either beverage with sugar probably should be minimized,” said Cheryl Bushnell, MD, MHS, of Wake Forest University School of Medicine in Winston-Salem, North Carolina, and chair of the American Stroke Association (ASA) 2024 Guideline for the Primary Prevention of Stroke.
Taylor Wallace, PhD, a certified food scientist, said, “most people should consume a cup or two of unsweetened tea per day in moderation for cardiometabolic health. It is an easy step in the right direction for good health but not a cure-all.”
When it comes to coffee, adults who like it should drink it “in moderation — just lay off the cream and sugar,” said Wallace, adjunct associate professor at George Washington University, Washington, DC, and Tufts University, Boston, Massachusetts.
“A cup or two of black coffee with low-fat or nonfat milk with breakfast is a healthy way to start the day, especially when you’re like me and have an 8-year-old that is full of energy!” Wallace said.
The Skinny on Soda
When it comes to sugar-sweetened and diet beverages, data from the Nurses’ Health Study and Health Professionals Follow-Up Study, showed a 16% increased risk for stroke with one or more daily servings of sugar-sweetened or low-calorie soda per day (vs none), independent of established dietary and nondietary cardiovascular risk factors.
In the Women’s Health Initiative Observational Study of postmenopausal women, a higher intake of artificially sweetened beverages was associated with increased risk for all stroke (adjusted hazard ratio [aHR], 1.23), ischemic stroke (aHR, 1.31), coronary heart disease (aHR, 1.29) and all-cause mortality (aHR, 1.16).
In the Framingham Heart Study Offspring cohort, consumption of one can of diet soda or more each day (vs none) was associated with a nearly threefold increased risk for stroke and dementia over a 10-year follow-up period.
A separate French study showed that total artificial sweetener intake from all sources was associated with increased overall risk for cardiovascular and cerebrovascular disease.
However, given the limitations of these studies, it’s hard to draw any firm conclusions, Wallace cautioned.
“We know that sugar-sweetened beverages are correlated with weight gain and cardiometabolic dysfunction promotion in children and adults,” he said.
Yet, “there really isn’t any convincing evidence that diet soda has much impact on human health at all. Most observational studies are mixed and likely very confounded by other diet and lifestyle factors. That doesn’t mean go overboard; a daily diet soda is probably fine, but that doesn’t mean go drink 10 of them every day,” he added.
Alcohol: Moderation or Abstinence?
Evidence on alcohol use and stroke risk have been mixed over the years. For decades, the evidence was suggestive that a moderate amount of alcohol daily (one to two drinks in men and one drink in women) may be beneficial at reducing major vascular outcomes.
Yet, over the past few years, some research has found no evidence of benefit with moderate alcohol intake. And the detrimental effects of excessive alcohol use are clear.
A large meta-analysis showed that light to moderate alcohol consumption (up to one drink per day) was associated with a reduced risk for ischemic stroke. However, heavy drinking (more than two drinks per day) significantly increased the risk for both ischemic and hemorrhagic stroke.
A separate study showed young adults who are moderate to heavy drinkers are at increased risk for stroke — and the risk increases with more years of imbibing.
In the INTERSTROKE study, high to moderate alcohol consumption was associated with increased stroke risk, whereas low alcohol consumption conferred no increased risk.
However, Bushnell pointed out that the study data was derived from based on self-report, and that other healthy behaviors may counteract the risk for alcohol consumption.
“For alcohol, regardless of stroke risk, the most important data shows that any alcohol consumption is associated with worse cognitive function, so generally, the lower the alcohol consumption the better,” Bushnell said.
She noted that, currently, the American Heart Association (AHA)/ASA recommend a maximum of two drinks per day for men and one drink per day for women to reduce stroke risk.
“However, the data for the risk for cognitive impairment with any alcohol is convincing and should be kept in mind in addition to the maximum alcohol recommended by the AHA/ASA,” Bushnell advised.
“We know excessive intake puts you at major risk for CVD, cancer, cognitive decline, and a whole host of other health ailments — no question there,” said Wallace.
The impact of moderate intake, on the other hand, is less clear. “Alcohol is a highly biased and political issue and the evidence (or lack thereof) on both sides is shoddy at best,” Wallace added.
A key challenge is that accurate self-reporting of alcohol intake is difficult, even for scientists, and most studies rely on self-reported data from observational cohorts. These often include limited dietary assessments, which provide only a partial picture of long-term consumption patterns, Wallace noted.
“The short answer is we don’t know if moderation is beneficial, detrimental, or null with respect to health,” he said.
Bushnell reports no relevant disclosures. Wallace (www.drtaylorwallace.com) is CEO of Think Healthy Group; editor of The Journal of Dietary Supplements, deputy editor of The Journal of the American Nutrition Association (www.nutrition.org), nutrition section editor of Annals of Medicine, and an advisory board member with Forbes Health.

In a recent UK Biobank study, consumption of coffee or tea was associated with reduced risk for stroke and dementia, with the biggest benefit associated with consuming both beverages.
Specifically, the investigators found that individuals who drank two to three cups of coffee and two to three cups of tea per day had a 30% decrease in incidence of stroke and a 28% lower risk for dementia versus those who did not.
A recent systematic review and dose-response meta-analysis showed that each daily cup increase in tea was associated with an average 4% reduced risk for stroke and a 2% reduced risk for cardiovascular disease (CVD) events.
The protective effect of coffee and tea on stroke risk may be driven, in part, by flavonoids, which have antioxidant and anti-inflammatory properties, as well as positive effects on vascular function.
“The advice to patients should be that coffee and tea may protect against stroke, but that sweetening either beverage with sugar probably should be minimized,” said Cheryl Bushnell, MD, MHS, of Wake Forest University School of Medicine in Winston-Salem, North Carolina, and chair of the American Stroke Association (ASA) 2024 Guideline for the Primary Prevention of Stroke.
Taylor Wallace, PhD, a certified food scientist, said, “most people should consume a cup or two of unsweetened tea per day in moderation for cardiometabolic health. It is an easy step in the right direction for good health but not a cure-all.”
When it comes to coffee, adults who like it should drink it “in moderation — just lay off the cream and sugar,” said Wallace, adjunct associate professor at George Washington University, Washington, DC, and Tufts University, Boston, Massachusetts.
“A cup or two of black coffee with low-fat or nonfat milk with breakfast is a healthy way to start the day, especially when you’re like me and have an 8-year-old that is full of energy!” Wallace said.
The Skinny on Soda
When it comes to sugar-sweetened and diet beverages, data from the Nurses’ Health Study and Health Professionals Follow-Up Study, showed a 16% increased risk for stroke with one or more daily servings of sugar-sweetened or low-calorie soda per day (vs none), independent of established dietary and nondietary cardiovascular risk factors.
In the Women’s Health Initiative Observational Study of postmenopausal women, a higher intake of artificially sweetened beverages was associated with increased risk for all stroke (adjusted hazard ratio [aHR], 1.23), ischemic stroke (aHR, 1.31), coronary heart disease (aHR, 1.29) and all-cause mortality (aHR, 1.16).
In the Framingham Heart Study Offspring cohort, consumption of one can of diet soda or more each day (vs none) was associated with a nearly threefold increased risk for stroke and dementia over a 10-year follow-up period.
A separate French study showed that total artificial sweetener intake from all sources was associated with increased overall risk for cardiovascular and cerebrovascular disease.
However, given the limitations of these studies, it’s hard to draw any firm conclusions, Wallace cautioned.
“We know that sugar-sweetened beverages are correlated with weight gain and cardiometabolic dysfunction promotion in children and adults,” he said.
Yet, “there really isn’t any convincing evidence that diet soda has much impact on human health at all. Most observational studies are mixed and likely very confounded by other diet and lifestyle factors. That doesn’t mean go overboard; a daily diet soda is probably fine, but that doesn’t mean go drink 10 of them every day,” he added.
Alcohol: Moderation or Abstinence?
Evidence on alcohol use and stroke risk have been mixed over the years. For decades, the evidence was suggestive that a moderate amount of alcohol daily (one to two drinks in men and one drink in women) may be beneficial at reducing major vascular outcomes.
Yet, over the past few years, some research has found no evidence of benefit with moderate alcohol intake. And the detrimental effects of excessive alcohol use are clear.
A large meta-analysis showed that light to moderate alcohol consumption (up to one drink per day) was associated with a reduced risk for ischemic stroke. However, heavy drinking (more than two drinks per day) significantly increased the risk for both ischemic and hemorrhagic stroke.
A separate study showed young adults who are moderate to heavy drinkers are at increased risk for stroke — and the risk increases with more years of imbibing.
In the INTERSTROKE study, high to moderate alcohol consumption was associated with increased stroke risk, whereas low alcohol consumption conferred no increased risk.
However, Bushnell pointed out that the study data was derived from based on self-report, and that other healthy behaviors may counteract the risk for alcohol consumption.
“For alcohol, regardless of stroke risk, the most important data shows that any alcohol consumption is associated with worse cognitive function, so generally, the lower the alcohol consumption the better,” Bushnell said.
She noted that, currently, the American Heart Association (AHA)/ASA recommend a maximum of two drinks per day for men and one drink per day for women to reduce stroke risk.
“However, the data for the risk for cognitive impairment with any alcohol is convincing and should be kept in mind in addition to the maximum alcohol recommended by the AHA/ASA,” Bushnell advised.
“We know excessive intake puts you at major risk for CVD, cancer, cognitive decline, and a whole host of other health ailments — no question there,” said Wallace.
The impact of moderate intake, on the other hand, is less clear. “Alcohol is a highly biased and political issue and the evidence (or lack thereof) on both sides is shoddy at best,” Wallace added.
A key challenge is that accurate self-reporting of alcohol intake is difficult, even for scientists, and most studies rely on self-reported data from observational cohorts. These often include limited dietary assessments, which provide only a partial picture of long-term consumption patterns, Wallace noted.
“The short answer is we don’t know if moderation is beneficial, detrimental, or null with respect to health,” he said.
