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. An artificial intelligence (AI)–based program uses all the known data on patients and their types of illness and creates a “twin” that can be used over and over to simulate disease progression, test treatments, and predict individual responses to therapies.

“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.

Globally, nearly one in three cases of oral cancer can be attributed to use of smokeless tobacco and areca nut products, according to a new study from the International Agency for Research on Cancer (IARC), a part of the World Health Organization (WHO).

“Smokeless tobacco and areca nut products are available to consumers in many different forms across the world, but consuming smokeless tobacco and areca nut is linked to multiple diseases, including oral cancer,” Harriet Rumgay, PhD, a scientist in the Cancer Surveillance Branch at IARC and first author of the study in Lancet Oncology, said in a news release.

Worldwide, about 300 million people use smokeless tobacco and 600 million people use areca (also called betel) nut, one of the most popular psychoactive substances in the world after nicotine, alcohol, and caffeine. Smokeless tobacco products are consumed without burning and can be chewed, sucked, inhaled, applied locally, or ingested. Areca nut is the seed of the areca palm and can be consumed in various forms.

“Our estimates highlight the burden these products pose on health care and the importance of prevention strategies to reduce consumption of smokeless tobacco and areca nut,” Rumgay said.

According to the new report, in 2022, an estimated 120,200 of the 389,800 (30.8%) global cases of oral cancer were attributable to these products.

More than three quarters (77%) of attributable cases were among men and about one quarter (23%) among women.

The vast majority (96%) of all oral cancer cases caused by smokeless tobacco and areca nut use occurred in low- and middle-income countries.

Regions with the highest burden of oral cancers from these products were Southcentral Asia — with 105,500 of 120,200 cases (nearly 88%), including 83,400 in India, 9700 in Bangladesh, 8900 in Pakistan, and 1300 in Sri Lanka — followed by Southeastern Asia with a total of 3900 cases (1600 in Myanmar, 990 in Indonesia, and 785 in Thailand) and East Asia with 3300 cases (3200 in China).
 

Limitations and Action Points

The authors noted a limitation of the analysis is not accounting for the potential synergistic effects of combined use of smokeless tobacco or areca nut products with other risk factors for oral cancer, such as smoking tobacco or drinking alcohol.

The researchers explained that combined consumption of smokeless tobacco or areca nut, smoked tobacco, and alcohol has a “multiplicative effect” on oral cancer risk, with reported odds ratios increasing from 2.7 for smokeless tobacco only, 7.0 for smoked tobacco only, and 1.6 for alcohol only to 16.2 for all three exposures (vs no use).

However, the proportion of people who chewed tobacco and also smoked in countries with high smokeless tobacco or areca nut use was small. In India, for example, 6% of men and 0.5% of women in 2016-2017 were dual users of both smoked and smokeless tobacco, compared with 23% of men and 12% of women who only used smokeless tobacco.

Overall, curbing or preventing smokeless tobacco and areca nut use could help avoid many instances of oral cancer.

Despite “encouraging trends” in control of tobacco smoking in many regions of the world over the past two decades, progress in reducing the prevalence of smokeless tobacco consumption has stalled in many countries that are major consumers, the authors said.

Compounding the problem, areca nut does not fall within the WHO framework of tobacco control and there are very few areca nut control policies worldwide.

Smokeless tobacco control must be “prioritized” and a framework on areca nut control should be developed with guidelines to incorporate areca nut prevention into cancer control programs, the authors concluded.

Funding for the study was provided by the French National Cancer Institute. The authors had no relevant disclosures.

Smokeless tobacco control must be “prioritized” and a framework on areca nut control should be developed with guidelines to incorporate areca nut prevention into cancer control programs, the authors concluded.

Funding for the study was provided by the French National Cancer Institute. The authors had no relevant disclosures.

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.

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.

TOPLINE:

Receiving radiotherapy after prostatectomy does negatively affect long-term health-related quality of life, including sexual function, urinary incontinence, and urinary irritation, but the timing of radiation after prostatectomy — within a year or over a year from surgery — does not appear to significantly affect patients’ quality of life over the long term, a recent analysis finds.

METHODOLOGY:

• Delaying radiotherapy after prostatectomy can help avoid overtreatment and mitigate genitourinary and erectile toxic effects. However, few studies have compared long-term patient-reported health-related quality-of-life outcomes on the basis of the timing of postprostatectomy radiotherapy.
• Researchers evaluated 1203 men (median age, 60.5 years; 92% were White and 6.8% were Black) with localized prostate cancer who underwent radical prostatectomy from the PROST-QA (2003-2006) and RP2 Consortium (2010-2013). Among these patients, 1082 underwent surgery only, 57 received early radiotherapy (within 12 months of surgery), and 64 underwent late radiotherapy (12 months or more after surgery).
• Patients who received early radiotherapy were more likely to receive androgen deprivation therapy than those who underwent late radiotherapy (40.4% vs 12.5%; P < .001).
• Primary outcome was health-related quality of life measured using the Expanded Prostate Cancer Index Composite at baseline, 2, 6, and 12 months, and annually after that. Health-related quality-of-life measures included sexual function, urinary incontinence, urinary irritation and/or obstruction, and bowel or rectal function.
• The median follow-up duration was 85.6 months.

TAKEAWAY:

• Postprostatectomy radiotherapy was associated with a significantly greater decline in health-related quality of life across all domains, including sexual function and urinary incontinence.
• Patients who received early radiation initially experienced worse urinary incontinence and sexual health, compared with patients in the late group, but the early group also had higher-risk disease and were more likely to receive concurrent androgen deprivation therapy.
• In the long term, the early radiotherapy group experienced more pronounced recovery of sexual function, urinary irritation, and urinary incontinence than the late radiotherapy group.
• Ultimately, patients in the early radiotherapy group had similar, potentially better, long-term health-related quality-of-life domain scores than those in the late group over the long term. For instance, the likelihood of being pad free increased for patients treated early with radiation, while it decreased for those treated late. In patients who received early radiation, the rate of freedom from pad use increased from 39% before radiation to 67% at the sixth follow-up visit after radiation, while it decreased from 73% to 48% in those who received late radiation.

IN PRACTICE:

“Long-term patient-reported sexual, incontinence, and urinary irritative outcomes did not significantly differ between early vs late postprostatectomy [radiotherapy],” the authors said. In fact, “men receiving early [radiation] experienced greater recovery of these toxicity domains and achieved similar, and possibly better, domain scores as those receiving late [radiation] at long-term follow-up.” Overall, “these results may help guide treatment counseling and support consideration of early [radiotherapy] after prostatectomy for men at particularly high risk of recurrence and metastasis.”

SOURCE:

The study, led by Sagar A. Patel, MD, MSc, Emory University in Atlanta, was published online in JAMA Network Open.

LIMITATIONS:

The early and late postprostatectomy radiotherapy groups were relatively small and underpowered to detect statistically significant differences between groups. The study has a nonrandomized design, which may introduce unaccounted for imbalances among the different groups. The study did not directly compare health-related quality of life between patients receiving adjuvant vs salvage radiotherapy.

DISCLOSURES:

This study received funding from National Institutes of Health grants and the Paul Calabresi Career Development Award for Clinical Oncology. Several authors reported receiving personal fees, grants, and having other ties with various sources. Additional disclosures are noted in the original article.

TOPLINE:

Low-dose oral minoxidil (LDOM), used off-label to treat alopecia, does not significantly affect blood pressure (BP) in patients with alopecia, but is associated with a slight increase in heart rate and a 5% incidence of hypotensive symptoms.

METHODOLOGY:

• Researchers conducted a systematic review and meta-analysis of 16 studies, which involved 2387 patients with alopecia (60.7% women) who received minoxidil, a vasodilator originally developed as an antihypertensive, at doses of 5 mg or less per day.
• Outcomes included changes in mean arterial pressure, systolic BP, diastolic BP, and heart rate.
• Mean differences were calculated between pretreatment and posttreatment values.

TAKEAWAY:

• Hypotensive symptoms were reported in 5% patients, with no significant hypotensive episodes. About 1.8% patients experienced lightheadedness or syncope, 1.2% experienced dizziness, 0.9% had tachycardia, and 0.8% had palpitations.
• LDOM did not significantly alter systolic BP (mean difference, –0.13; 95% CI, –2.67 to 2.41), diastolic BP (mean difference, –1.25; 95% CI, –3.21 to 0.71), and mean arterial pressure (mean difference, –1.92; 95% CI, –4.00 to 0.17).
• LDOM led to a significant increase in heart rate (mean difference, 2.67 beats/min; 95% CI, 0.34-5.01), a difference the authors wrote would “likely not be clinically significant for most patients.”
• Hypertrichosis was the most common side effect (59.6%) and reason for stopping treatment (accounting for nearly 35% of discontinuations).

IN PRACTICE:

“LDOM appears to be a safe treatment for alopecia with no significant impact on blood pressure,” the authors wrote, noting that the study “addresses gaps in clinical knowledge involving LDOM.” Based on their results, they recommended that BP and heart rate “do not need to be closely monitored in patients without prior cardiovascular risk history.”

SOURCE:

The study was led by Matthew Chen, BS, Stony Brook Dermatology in New York. It was published online in The Journal of the American Academy of Dermatology.

LIMITATIONS:

The studies included had small sample sizes and retrospective designs, which may limit the reliability of the findings. Additional limitations include the absence of control groups, a potential recall bias in adverse effect reporting, and variability in dosing regimens and BP monitoring. 

DISCLOSURES:

The authors reported no external funding or conflicts of interest.

“LDOM appears to be a safe treatment for alopecia with no significant impact on blood pressure,” the authors wrote, noting that the study “addresses gaps in clinical knowledge involving LDOM.” Based on their results, they recommended that BP and heart rate “do not need to be closely monitored in patients without prior cardiovascular risk history.”

SOURCE:

The study was led by Matthew Chen, BS, Stony Brook Dermatology in New York. It was published online in The Journal of the American Academy of Dermatology.

LIMITATIONS:

The studies included had small sample sizes and retrospective designs, which may limit the reliability of the findings. Additional limitations include the absence of control groups, a potential recall bias in adverse effect reporting, and variability in dosing regimens and BP monitoring. 

DISCLOSURES:

The authors reported no external funding or conflicts of interest.

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.

Women with endometriosis have a much higher risk of being diagnosed with several psychiatric disorders during the postpartum period according to an oral abstract presented at the American Society for Reproductive Medicine’s 2024 Scientific Congress and Expo in Denver, Colorado.

Researchers compared rates of postpartum depression, anxiety, mood disturbance (temporary low or anxious mood requiring no treatment), and obsessive-compulsive disorder (OCD) diagnoses among over 200 million adult women from 67 healthcare organizations who had a child between 2005 and 2023.

Within a year after giving birth, women with prepregnancy endometriosis were 25% more likely to be diagnosed with postpartum depression, 85% more likely to be diagnosed with postpartum mood disturbance, 44% more likely to be diagnosed with anxiety, and 1.26 times more likely to be diagnosed with OCD.

About 75% of women studied had no preexisting depression. This population had a 17% higher risk of receiving a postpartum depression diagnosis, a 95% higher risk of receiving an OCD diagnosis, a 72% higher risk of receiving a postpartum mood disturbance diagnosis, and a 38% risk of receiving an anxiety diagnosis.

Among women without preexisting depression, the risk increased by 64% for OCD, 42% for postpartum mood disturbance, and 25% for anxiety, while the risk for postpartum depression was negligible, indicating that women already experiencing depression likely have a higher baseline risk for worsening symptoms postpartum, said the study’s lead author Tina Yi-Jin Hsieh, MD, MPH, biomedical researcher at Harvard Medical School in Boston, Massachusetts.

“We think that because preexisting depression is the more dominant risk factor, it doesn’t really matter if you have another additional risk factor like endometriosis to really change the risk of postpartum depression,” said Hsieh.

Endometriosis is a debilitating condition in which tissue similar to uterine lining grows on the outside of the uterus, causing chronic pain and infertility. It affects between 6% and 10% of women worldwide and takes an average of between 4 and 11 years to be diagnosed. It has been linked to depression and anxiety disorders, yet the study authors say there’s little research examining its impact on women in the year after giving birth.

“Endometriosis is a complex condition that can affect both physical and mental health over much of a person’s life,” said Anna Modest, PhD, assistant professor of Obstetrics, Gynecology, and Reproductive Biology at Harvard Medical School and a study author. “Perinatal and maternal mental health can have a huge impact on children and their family — we need to better understand who is at risk for challenges in the postpartum period.”

“Most chronic medical illnesses, particularly those causing pain, have been shown to increase the risk of mood disorders,” said Ripal Shah, MD, MPH, clinical associate professor of Psychiatry and Behavioral Sciences at Stanford Medicine in California. Shah specializes in reproductive psychiatry and was not associated with the study.

“What’s interesting about endometriosis though is that genome-wide association studies have shown that there may be a genetic predisposition for some women to develop both endometriosis and a mood disorder,” said Shah.

A 2023 study suggested that endometriosis, anxiety, and depression may be connected through a shared genetic basis.

But the experience patients with endometriosis go through also lends itself to the development of mood disorders, said Daniel Ginn, DO, assistant clinical professor of Obstetrics and Gynecology at the David Geffen School of Medicine at the University of California, Los Angeles. Ginn specializes in the treatment of endometriosis and was not a part of the study.

Beyond postpartum depression, Ginn wasn’t surprised by the association of endometriosis with anxiety or OCD because what he hears from patients “on a daily basis is the telling of a history that has been hallmarked by not being listened to, not being believed, and not having symptoms managed well.”

As a result, he said many patients focus heavily on learning about their condition, coming into office visits with binders full of test results and information in an effort to understand and manage it themselves. This “does lead to a certain sense of a need to grasp for control because no one else is helping them [treat their condition effectively].”

He added: “I find it hard to believe that anxiety and OCD were preexisting of the conditions rather than the consequence of a long-term suboptimally managed disease.”

The authors reported no disclosures or sources of funding.

“We think that because preexisting depression is the more dominant risk factor, it doesn’t really matter if you have another additional risk factor like endometriosis to really change the risk of postpartum depression,” said Hsieh.

Endometriosis is a debilitating condition in which tissue similar to uterine lining grows on the outside of the uterus, causing chronic pain and infertility. It affects between 6% and 10% of women worldwide and takes an average of between 4 and 11 years to be diagnosed. It has been linked to depression and anxiety disorders, yet the study authors say there’s little research examining its impact on women in the year after giving birth.

“Endometriosis is a complex condition that can affect both physical and mental health over much of a person’s life,” said Anna Modest, PhD, assistant professor of Obstetrics, Gynecology, and Reproductive Biology at Harvard Medical School and a study author. “Perinatal and maternal mental health can have a huge impact on children and their family — we need to better understand who is at risk for challenges in the postpartum period.”

“Most chronic medical illnesses, particularly those causing pain, have been shown to increase the risk of mood disorders,” said Ripal Shah, MD, MPH, clinical associate professor of Psychiatry and Behavioral Sciences at Stanford Medicine in California. Shah specializes in reproductive psychiatry and was not associated with the study.

“What’s interesting about endometriosis though is that genome-wide association studies have shown that there may be a genetic predisposition for some women to develop both endometriosis and a mood disorder,” said Shah.

A 2023 study suggested that endometriosis, anxiety, and depression may be connected through a shared genetic basis.

But the experience patients with endometriosis go through also lends itself to the development of mood disorders, said Daniel Ginn, DO, assistant clinical professor of Obstetrics and Gynecology at the David Geffen School of Medicine at the University of California, Los Angeles. Ginn specializes in the treatment of endometriosis and was not a part of the study.

Beyond postpartum depression, Ginn wasn’t surprised by the association of endometriosis with anxiety or OCD because what he hears from patients “on a daily basis is the telling of a history that has been hallmarked by not being listened to, not being believed, and not having symptoms managed well.”

As a result, he said many patients focus heavily on learning about their condition, coming into office visits with binders full of test results and information in an effort to understand and manage it themselves. This “does lead to a certain sense of a need to grasp for control because no one else is helping them [treat their condition effectively].”

He added: “I find it hard to believe that anxiety and OCD were preexisting of the conditions rather than the consequence of a long-term suboptimally managed disease.”

Although hysterectomy remains the most common procedure for treating fibroids and fibroids are the leading indication for hysterectomy, its long-term sequelae make less invasive alternatives the better choice for managing most of these myometrial masses, an invited clinical practice paper in the New England Journal of Medicine (NEJM) asserts.

The practice summary also calls for earlier identification and treatment of fibroid disease and may raise awareness among general gynecologists and primary care physicians less familiar with newer treatments.

Based on a review of evidence and existing formal guidelines, the paper urges wider use of uterus-sparing approaches such as hormone therapy, uterine-artery embolization, focused ultrasound ablation, and radiofrequency ablation. Authored by ob.gyns. Elizabeth A. Stewart, MD, and Shannon K. Laughlin-Tommaso, MD, MPH, of the Mayo Clinic in Rochester, Minnesota, the document also features textbook-style diagrams illustrating procedures.

“To clarify, this is not a new guidance but an invited clinical practice paper,” Laughlin-Tommaso told this news organization. “I believe NEJM recognized the gap in knowledge among all providers, for early diagnosis of uterine fibroids, especially in young patients and those presenting with anemia.”

The less invasive treatments highlighted in the paper can help women recover faster and resume their normal activities more quickly, said Laughlin-Tommaso. “Additionally, many studies have now shown that there are health benefits to keeping the uterus and the ovaries.”

Despite multiple uterine-sparing options, however, a recent study in a commercially insured population found nearly 60% of fibroid patients undergoing hysterectomy had never received a prior conservative treatment.

Why hysterectomy for a benign condition? Hysterectomy, which is universally available in ob.gyn. practices, makes decision-making easier for medical providers and patients, Laughlin-Tommaso explained. “It’s the only treatment that is definitive in that patients will not have bleeding or fibroids in the future and providers don’t have to determine which fibroids to treat or remove.”

More common in Black women, fibroids affect up to 80% of persons with a uterus during their lifetime and up to 50% have symptoms such as heavy and prolonged menstrual bleeding, anemia-associated fatigue, pelvic pressure, and menstrual and nonmenstrual pain, the authors noted. These lesions can also compress nearby structures causing painful intercourse, constipation, and urinary frequency, urgency, or retention.

In 2021 the American College of Obstetricians and Gynecologists issued a practice bulletin on the management of symptomatic uterine leiomyomas, similarly endorsing individualized care that accounts for the desire to preserve fertility or the uterus, increase quality of life, and reduce symptoms. It, too, recommended medical management as first-line treatment for symptomatic fibroids.

“This paper will be helpful for clinicians by covering some of the newer options such as gonadotropin-releasing hormone antagonists introduced in the past 5 years and tailoring treatment to patients depending on whether they still want to conceive,” Sandra M. Hurtado, MD, an ob.gyn. and an assistant professor at UTHealth Houston Medical Center and McGovern Medical School in Houston, Texas, said in an interview. “And the illustrations will be useful to doctors who are not gynecologists and will help to explain the interventional options to patients,” added Hurtado, who was not involved in the paper.

Offering another outside perspective on the paper, Charles J. Ascher-Walsh, MD, senior system vice chair for gynecology and division director of urogynecology in the Raquel and Jaime Gilinski Department of Obstetrics, Gynecology and Reproductive Science at Mount Sinai in New York City, called it a useful though not new summary. Reaching the wider audience of NEJM may raise awareness of newer fibroid therapies among general, nonspecialist ob.gyns., whose practices may concentrate largely on obstetrics, he added, “and the excellent illustrations clarify the treatment options.” In his view, broader awareness may increase much-needed funding for this neglected area of research.

Among the paper’s recommendations:

Diagnosis

Pelvic ultrasonography is the most cost-effective imaging method, providing information on size, location, and number of fibroids and ruling out adnexal masses. It is limited, however, by less-accurate resolution if the uterine volume is greater than 375 mL or if fibroids number more than four.

Medical Alternatives to Hysterectomy

Early diagnosis and first-line medical therapies are recommended.

Contraceptive hormones to control heavy menstrual bleeding are the first step in most algorithms for treating fibroid-related bleeding, despite low-quality evidence.

Nonsteroidal anti-inflammatory agents and tranexamic acid during menstruation also limit heavy menses but have more evidence of efficacy for idiopathic heavy menses.

Gonadotropin-releasing hormone (GnRH) agonists in depot form are approved for short-term preoperative therapy. While they cause amenorrhea in nearly 90% of patients and reduce uterine volume by 30%-60%, they have a high incidence of hypogonadal symptoms, including bone loss and hot flushes. They also cause a “steroidal flare” when the stored gonadotropins are released and cause subsequent heavy menstrual bleeding with the rapid decrease in estrogen levels. 

Oral GnRH antagonist combinations are a major therapeutic advance, pairing a GnRH antagonist (such as elagolix or relugolix, which rapidly inhibit ovarian steroidogenesis) with estradiol and progestin at doses equivalent to systemic levels in the early follicular phase of the menstrual cycle.

In clinical trials these combinations decreased heavy menstrual bleeding by 50%-75%, pain by 40%-50%, and bulk-related symptoms through a 10% decrease in uterine volume. Side effects are few, with hot flushes, headaches, and nausea occurring in fewer than 20% of participants.
 

Smaller fibroids in the submucosal to intramural spaces can be treated transcervically, while larger lesions of any type or smaller subserosa fibroids are treated abdominally.

Uterine-artery embolization uses minimally invasive radiologically guided catheterization to release embolic particles directly into both uterine arteries. This process causes ischemic infarction of the fibroids and decreases bleeding, pain, and bulk-related symptoms.

Other procedures shrink individual fibroids with energy that creates coagulative necrosis. These include focused ultrasound ablation (with MRI or ultrasound guidance) and radiofrequency ablation (with laparoscopic or transcervical ultrasound guidance).

Unlike uterine-artery embolization, which treats all fibroids concurrently, these therapies require individual targeting of fibroids.

Radiofrequency ablation can be done concurrently with other surgical therapies, such as laparoscopic excision of endometriosis or hysteroscopic myomectomy.

Myomectomy, or the surgical removal of fibroids, is most often used in persons actively seeking pregnancy or having very large fibroids in whom shrinkage would be inadequate. Most guidelines recommend surgical excision rather than shrinking procedures to optimize fertility. However, myomectomy often commits patients to future cesarean section, which increases pregnancy-related morbidity.

Although myomectomy is seen as superior to uterine-artery embolization for improving quality of life, both approaches provide substantial symptom relief.
 

Recurrence

Incidence of recurring fibroids is high, with, for example, new fibroids developing in approximately 50% of persons within 5 years of myomectomy.

Earlier this year, a large cohort study reported that myomectomy was best for avoiding reintervention after surgical leiomyoma management.

Reintervention rates vary according to procedure, patient age, disease extent, and symptoms and can be as high as 33% up to 5 years after treatment, with lower percentages seen among persons older than 45 years of age.
 

Hysterectomy

Minimally invasive hysterectomy is recommended. Drawbacks to hysterectomy include perioperative risk and concomitant oophorectomy, which was common until the early 2000s when large cohort studies showed elevated risks of death, cardiovascular disease, dementia, and other illnesses compared with hysterectomy plus ovarian conservation. Oophorectomy but not hysterectomy rates have since decreased.

Still needing study, according to Laughlin-Tommaso are the underlying reasons for health disparities in fibroids, especially among Black and Latina individuals. “Some studies have found associations with vitamin D deficiency and with stress and racism,” she said.

Looking ahead, the authors stressed the need for a fibroid risk-prediction model, a staging system, and large randomized trials of treatment effectiveness. Also needed are methods for primary and secondary prevention. “Earlier screening and medical treatment in primary care settings could potentially minimize morbidity and the incidence of unnecessary hysterectomies, and primary care–based screening trials are warranted,” they wrote.
 

In addition to procedural illustrations the practice document includes a vignette of a 33-year-old never-pregnant Black woman (but desiring motherhood) with heavy menstrual bleeding, abdominal bloating, and non–iron deficiency anemia. Evaluation for thalassemia and sickle cell anemia is negative, but ultrasonography reveals an enlarged uterus with multiple fibroids and normal ovaries.

In line with the clinical review, the authors prescribe oral GnRH agonist combination therapy, plus iron and multivitamin supplementation, and recommend annual reassessment — earlier if pregnancy is desired or if symptoms escalate. Since the patient prioritizes fertility, hysterectomy would be appropriate only if she had biopsy-proven cancer. 

The authors received no external funding for this practice paper, but both have funding from the National Institutes of Health for fibroid research. Laughlin-Tommaso reported royalties from UpToDate. Stewart reported research support from the Agency for Healthcare Research and Quality, and speaking, data-monitoring, and consulting fees for various private companies, including AbbVie, Anylam Pharmaceuticals, ASKA Pharma, and Myovant Sciences. She holds a patent on treatment for abnormal uterine bleeding and has been involved in CME for various medical educational agencies. Hurtado and Ascher-Walsh had no relevant conflicts of interest to declare.

TOPLINE:

Heat waves are associated with an increase in heat-related emergency department visits, hospitalizations, and deaths among dually eligible individuals older than 65 years.

METHODOLOGY:

• The researchers conducted a retrospective time-series study using national Medicare and Medicaid data from 2016 to 2019 to assess the link between heat waves during warm months and adverse health events.
• A total of 5,448,499 dually eligible individuals (66% women; 20% aged ≥ 85 years) were included from 28,404 zip code areas across 50 states and Washington, DC.
• Heat waves were defined as three or more consecutive days of extreme heat with a maximum temperature of at least 90 °F and within the 97th percentile of daily maximum temperatures for each zip code.
• Primary outcomes were daily counts of heat-related emergency department visits and hospitalizations.
• Secondary outcomes were all-cause and heat-specific emergency department visits, all-cause and heat-specific hospitalizations, deaths, and long-term nursing facility placements within 3 months after a heat wave.

TAKEAWAY:

• Heat waves were associated with a 10% increase in heat-related emergency department visits (incidence rate ratio [IRR], 1.10; 95% CI, 1.08-1.12) and a 7% increase in heat-related hospitalizations (IRR, 1.07; 95% CI, 1.04-1.09).
• Mortality rates were 4% higher during heat wave days than during non–heat wave days (IRR, 1.04; 95% CI, 1.01-1.07).
• No significant difference was found in rates of long-term nursing facility placements or heat-related emergency department visits for nursing facility residents.
• All racial and ethnic groups showed higher incidence rates of heat-related emergency department visits during heat waves, especially among beneficiaries identified as Asian (IRR, 1.21; 95% CI, 1.12-1.29). Rates were higher among individuals residing in the Northwest, Ohio Valley, and the West.

IN PRACTICE:

“In healthcare settings, clinicians should incorporate routine heat wave risk assessments into clinical practice, especially in regions more susceptible to extreme heat, for all dual-eligible beneficiaries and other at-risk patients,” wrote Jose F. Figueroa, MD, MPH, of the Harvard T.H. Chan School of Public Health in Boston, in an invited commentary. “Beyond offering preventive advice, clinicians can adjust medications that may increase their patients’ susceptibility during heat waves, or they can refer patients to social workers and social service organizations to ensure that they are protected at home.”

LIMITATIONS:

This study relied on a claims database to identify adverse events, which may have led to omissions in coding, particularly for heat-related conditions if the diagnostic codes for heat-related symptoms had not been adopted. This study did not adjust for variations in air quality or green space, which could have confounded the association of interest. Indoor heat exposures or adaptive behaviors, such as air conditioning use, were not considered. The analysis could not compare the association of heat waves with adverse events between those with dual eligibility and those without dual eligibility.

TOPLINE:

Heat waves are associated with an increase in heat-related emergency department visits, hospitalizations, and deaths among dually eligible individuals older than 65 years.

METHODOLOGY:

• The researchers conducted a retrospective time-series study using national Medicare and Medicaid data from 2016 to 2019 to assess the link between heat waves during warm months and adverse health events.
• A total of 5,448,499 dually eligible individuals (66% women; 20% aged ≥ 85 years) were included from 28,404 zip code areas across 50 states and Washington, DC.
• Heat waves were defined as three or more consecutive days of extreme heat with a maximum temperature of at least 90 °F and within the 97th percentile of daily maximum temperatures for each zip code.
• Primary outcomes were daily counts of heat-related emergency department visits and hospitalizations.
• Secondary outcomes were all-cause and heat-specific emergency department visits, all-cause and heat-specific hospitalizations, deaths, and long-term nursing facility placements within 3 months after a heat wave.

TAKEAWAY:

• Heat waves were associated with a 10% increase in heat-related emergency department visits (incidence rate ratio [IRR], 1.10; 95% CI, 1.08-1.12) and a 7% increase in heat-related hospitalizations (IRR, 1.07; 95% CI, 1.04-1.09).
• Mortality rates were 4% higher during heat wave days than during non–heat wave days (IRR, 1.04; 95% CI, 1.01-1.07).
• No significant difference was found in rates of long-term nursing facility placements or heat-related emergency department visits for nursing facility residents.
• All racial and ethnic groups showed higher incidence rates of heat-related emergency department visits during heat waves, especially among beneficiaries identified as Asian (IRR, 1.21; 95% CI, 1.12-1.29). Rates were higher among individuals residing in the Northwest, Ohio Valley, and the West.

IN PRACTICE:

“In healthcare settings, clinicians should incorporate routine heat wave risk assessments into clinical practice, especially in regions more susceptible to extreme heat, for all dual-eligible beneficiaries and other at-risk patients,” wrote Jose F. Figueroa, MD, MPH, of the Harvard T.H. Chan School of Public Health in Boston, in an invited commentary. “Beyond offering preventive advice, clinicians can adjust medications that may increase their patients’ susceptibility during heat waves, or they can refer patients to social workers and social service organizations to ensure that they are protected at home.”
