In one of several recently published studies on the relationship between COVID-19 infection and asthma, asthma symptoms in children declined as the proportion of the US population vaccinated against COVID-19 increased, according to data drawn from the National Survey of Children’s Health (NSCH).

The inverse correlation between symptoms and vaccination was strong and statistically significant, according to investigators led by Matthew M. Davis, MD, Physician in Chief and Chief Scientific Officer, Nemours Children’s Health, Wilmington, Delaware.

“With each increase of 10 percentage points in COVID-19 vaccination coverage, the parent-reported child asthma symptoms prevalence decreased by 0.36 percentage points (P < .05),” Dr. Davis and his coinvestigators reported in a research letter published in JAMA Network Open.
 

Studies Explore Relationship of COVID and Asthma

The reduced risk of asthma symptoms with COVID-19 vaccination in children at the population level is just one of several recently published studies exploring the interaction between COVID-19 infection and asthma, but two studies that posed the same question did not reach the same conclusion.

In one, COVID-19 infection in children was not found to be a trigger for new-onset asthma, but the second found that it was. In a third study, the preponderance of evidence from a meta-analysis found that patients with asthma – whether children or adults – did not necessarily experience a more severe course of COVID-19 infection than in those without asthma.

The NSCH database study calculated state-level change in scores for patient-reported childhood asthma symptoms in the years in the years 2018-2019, which preceded the pandemic and the years 2020-2021, when the pandemic began. The hypothesis was that the proportion of the population 5 years of age or older who completed the COVID-19 primary vaccination would be inversely related to asthma symptom prevalence.

Relative to the 2018-2019 years, the mean rate of parent-reported asthma symptoms was 0.85% lower (6.93% vs 7.77%; P < .001) in 2020-2021, when the mean primary series COVID-19 vaccination rate was 72.3%.

The study was not able to evaluate the impact of COVID-19 vaccination specifically in children with asthma, because history of asthma is not captured in the NSCH data, but Dr. Davis contended that the reduction in symptomatic asthma among children with increased vaccination offers validation for the state-level findings.

“Moreover, the absence of an association of COVID-19 vaccination administered predominantly in 2021 with population-level COVID-19 mortality in 2020 serves as a negative control,” he and his colleagues wrote in their research letter.
 

Protection from Respiratory Viruses Seen for Asthma Patients

In an interview, Dr. Davis reported that these data are consistent with previous evidence that immunization against influenza also reduces risk of asthma symptoms. In a meta-analysis published in 2017, it was estimated that live vaccines reduced risk of influenza by 81% and prevented 59%-72% of asthma attacks leading to hospitalizations or emergency room visits.

“The similarity of our findings regarding COVID-19 vaccination to prior data regarding influenza vaccination underscores the importance of preventing viral illnesses in individuals with a history of asthma,” Dr. Davis said. It is not yet clear if this is true of respiratory syncytial virus (RSV). Because of the short time that the RSV vaccine has been available, it is too soon to conduct an analysis.

One message from this study is that “clinicians should continue to encourage COVID-19 vaccination for children because of its general benefits in preventing coronavirus-related illness and the apparent specific benefits for children with a history of asthma,” he said.

While vaccination appears to reduce asthmatic symptoms related to COVID-19 infection, one study suggests that COVID-19 does not trigger new-onset asthma. In a retrospective study published in Pediatrics, no association between COVID-19 infection and new-onset asthma could be made in an analysis of 27,423 children (ages, 1-16 years) from the Children’s Hospital of Philadelphia (CHOP) Care Network.

Across all the pediatric age groups evaluated, the consistent finding was “SARS-CoV-2 positivity does not confer an additional risk for asthma diagnosis at least within the first 18 months after a [polymerase chain reaction] test,” concluded the investigators, led by David A. Hill, MD, PhD, Division of Allergy and Immunology, CHOP, Philadelphia, Pennsylvania.
 

Risk of Asthma Doubled After COVID-19 Infection

However, the opposite conclusion was reached by investigators evaluating data from two cohorts of children ages 5-18 drawn from the TriNetX database, a global health research network with data on more than 250 million individuals. Cohort 1 included more than 250,000 children. These children had never received COVID-19 vaccination. The 50,000 patients in cohort 2 had all received COVID19 vaccination.

To compare the impact of COVID-19 infection on new-onset asthma, the patients who were infected with COVID-19 were compared with those who were not infected after propensity score matching over 18 months of follow-up.

In cohort 1, the rate of new onset asthma was more than twofold greater among those with COVID-19 infection (4.7% vs 2.0%). The hazard ratio (HR) of 2.25 had tight confidence intervals (95% CI, 2.158-2.367).

In cohort 2, the risk of new-onset asthma at 18 months among those who had a COVID-19 infection relative to those without was even greater (8.3% vs 3.1%). The relative risk approached a 3-fold increase (HR 2.745; 95% CI, 2.521-2.99).

The conclusion of these investigators, led by Chia-Chi Lung, PhD, Department of Public Health, Chung Shan Medical University, Taichung City, Taiwan, was that there is “a critical need for ongoing monitoring and customized healthcare strategies to mitigate the long-term respiratory impacts of COVID-19 in children.”

These health risks might not be as significant as once feared. In the recently published study from Environmental Health Insights, the goal of a meta-analysis was to determine if patients with asthma relative to those without asthma face a higher risk of serious disease from COVID-19 infection. The meta-analysis included studies of children and adults. The answer, according an in-depth analysis of 21 articles in a “scoping review,” was a qualified no.

Of the 21 articles, 4 concluded that asthma is a risk factor for serious COVID-19 infection, but 17 did not, according to Chukwudi S. Ubah, PhD, Department of Public Health, Brody School of Medicine, East Caroline University, Greenville, North Carolina.
 

None of These Questions are Fully Resolved

However, given the disparity in the results and the fact that many of the studies included in this analysis had small sample sizes, Dr. Ubah called for larger studies and studies with better controls. He noted, for example, that the studies did not consistently evaluate mitigating factors, such as used of inhaled or oral corticosteroids, which might affect risk of the severity of a COVID-19 infection.

Rather, “our findings pointed out that the type of medication prescribed for asthma may have implications for the severity of COVID-19 infection in these patients,” Dr. Ubah said in an interview.

Overall, the data do not support a major interaction between asthma and COVID-19, even if the data are not conclusive. Each of the senior authors of these studies called for larger and better investigations to further explore whether COVID-19 infection and preexisting asthma interact. So far, the data indicate that if COVID-19 infection poses a risk of precipitating new-onset asthma or inducing a more severe infection in children with asthma, it is low, but the degree of risk, if any, remains unresolved in subgroups defined by asthma treatment or asthma severity.

Dr. Davis, Dr. Hill, Dr. Lung, and Dr. Ubah reported no potential conflicts of interest. None of these studies received funding from commercial interests.

TOPLINE:

Compared with the general population, patients with urticaria had a 49% higher risk of developing cancer in the first year following diagnosis, which decreased to 6% in subsequent years, in a cohort study using Danish healthcare databases.

METHODOLOGY:

• Researchers conducted a retrospective cohort study using data from Danish healthcare registries and compared the incident cancer risk between patients with urticaria and the risk in the general population.
• They identified 87,507 patients (58% women) with a primary or secondary first-time hospital outpatient clinic, emergency room, or inpatient diagnosis of urticaria between 1980 and 2022, who were followed for a median of 10.1 years.
• Incident cancers, including nonmelanoma skin cancer, were identified using the Danish Cancer Registry and classified by the extent of spread at the time of diagnosis.
• This study computed the absolute cancer risk within the first year of an urticaria diagnosis and standardized incidence ratios (SIRs), with 95% CIs standardized to Danish national cancer rates.

TAKEAWAY:

• For the first year of follow-up, the absolute risk for all cancer types was 0.7%, and it was 29.5% for subsequent years. The overall SIR for all types of cancer was 1.09 (95% CI, 1.06-1.11), which was based on 7788 observed cancer cases compared with 7161 cases expected over the entire follow-up period.
• Within the first year of follow-up, 588 patients with urticaria were diagnosed with cancer, for an SIR of 1.49 (95% CI, 1.38-1.62) for all cancer types.
• After the first year, the SIR for all cancer sites decreased and stabilized at 1.06 (95% CI, 1.04-1.09), with 7200 observed cancer cases.
• The risk was highest for hematological cancers in the first year, particularly Hodgkin lymphoma (SIR, 5.35; 95% CI, 2.56-9.85).

IN PRACTICE:

“Our study suggests that urticaria may be a marker of occult cancer and that it is associated with a slightly increased long-term cancer risk,” the authors wrote.

SOURCE:

The study was led by Sissel B.T. Sørensen, departments of dermatology and rheumatology, Aarhus University Hospital, Aarhus, Denmark. It was published online on June 27, 2024, in the British Journal of Dermatology.

LIMITATIONS:

The study is limited by its observational design and reliance on registry data, which may be subject to misclassification or incomplete information. In addition, the study could not assess individual patient factors such as lifestyle or genetic predispositions that may influence cancer risk, and the results may not be generalizable to other populations. Finally, the exact biologic mechanisms linking urticaria and cancer remain unclear, warranting further investigation.

DISCLOSURES:

The study did not receive any funding. The authors reported that they had no relevant conflicts of interest.

Should a patient with high lipoprotein (a), or Lp(a), be started on low-dose aspirin?

This is the conundrum facing many physicians and patients, but even getting to that point will require more availability and coverage of tests and a greater appreciation of the risk associated with Lp(a), said cardiologists.
 

Lp(a): The Silent Risk

On Lp(a) Awareness Day, C. Michael Gibson, MD, MA, CEO of the Baim Institute for Clinical Research, Boston, Massachusetts, and PERFUSE took the opportunity to talk about his experiences with testing on X.

The professor of medicine at Harvard Medical School, also in Boston, said he was surprised to find that he had a very high calcium score, despite a low-density lipoprotein (LDL) cholesterol level of just 70 mg/dL. Eventually, he found out that he had a “very, very high Lp(a),” which was particularly concerning because his grandfather died of a heart attack at 45 years of age.

But how much risk does that represent?

A 2022 consensus statement from the European Atherosclerosis Society (EAS) highlighted that epidemiologic and genetic studies “strongly support a causal and continuous association between Lp(a) concentration and cardiovascular outcomes,” even at very low LDL cholesterol levels.

This is because Lp(a) has proinflammatory and proatherosclerotic properties, and high levels are associated with both micro- and macrocalcification of the aortic valve. Findings from a US registry study also suggest the threshold related to increased cardiovascular risk may differ for primary and secondary prevention populations (J Am Coll Cardiol. 2024 Mar 5;83[9]:873-886).

Lp(a) is, however, genetically determined, and there are no drugs available that directly lower levels, although some are on the horizon. In the meantime, the experts behind the consensus statement recommend that all adults be tested at least once in their lifetime.
 

Testing Cost and Availability

This recommendation has been translated into guidelines in “many, many” countries, said lead author Florian Kronenberg, MD, MAE, Institute of Genetic Epidemiology, Medical University of Innsbruck, Innsbruck, Austria, but “we are far away from reaching that goal.”

“We’ve got a real problem,” added Stephen Nicholls, MD, PhD, director of the Victorian Heart Institute and a professor of cardiology at Monash University, Melbourne, Australia, as there is “not a country in the world where there’s good access to Lp(a) testing.”

Dr. Kronenberg said that the consensus statement “created a kind of momentum” toward universal testing.

Ulrich Laufs, MD, PhD, professor and chair, Department of Cardiology, University Hospital Leipzig, Leipzig, Germany, agreed, saying that, overall, Lp(a) testing has “increased dramatically,” albeit from “extremely low levels.”

Dr. Kronenberg believes that “we have to be really patient.” He cited a lack of knowledge among physicians as one of the biggest barriers to greater uptake of testing.

“There is still no appreciation of the role of Lp(a),” agreed Alberico L. Catapano, MD, PhD, director of Cardiovascular Research and of the Lipoproteins and Atherosclerosis Laboratory of IRCCS Multimedica, Milan, Italy, and past president of the EAS.

“That’s why it’s not mentioned” to patients, he said. “What is really needed is to inform physician colleagues that Lp(a) is not only a risk factor but is the cause” of atherosclerotic cardiovascular disease (ASCVD).

Dr. Kronenberg said that the pressure for testing can often come from the patient themselves.

Physicians then question why the patient wants to be tested when there are no medications to treat it, he added. “We really tried very hard when we did the consensus paper to say that we should perform the test and give people advice on what to do.”

Dr. Catapano believes that another major obstacle is the cost of the test, which remains high “because very few people do it,” and there is some debate over which test to use.

Taken together, these issues have meant that “payers are really struggling with the idea of funding Lp(a),” said Dr. Nicholls, adding that “there seems to be this fixation on: ‘Well, if you can’t lower Lp(a), why measure it?’ ”

Rather than blame the payers, he says there is a need to educate about the science behind testing and underline that Lp(a) is an “important risk enhancer” for cardiovascular disease.

“Because if we’re going to make people pay out of pocket, then you’re creating a massive equity issue in that only those who can afford the test have it.”
 

High Lp(a) Now What?

But once the test has been performed, there then comes the question as to what to do about the result.

“Before we get anywhere near an agent that effectively lowers Lp(a) and get it into the clinic, there are lots of things that we can do today,” said Dr. Nicholls.

If someone has an intermediate or high background cardiovascular risk and they have got a high Lp(a) level, they “should be treated more intensively, as we know that high Lp(a) patients do better if their LDL cholesterol and their blood pressure is lower.”

For Dr. Catapano, this means having the “same mindset as you do with [a patient with] high blood pressure, high LDL cholesterol, and so on, because it’s exactly the same thing: It’s interacting with your other risk factors to increase your overall risk.”

Dr. Gibson agreed. Through a range of measures, including weight loss and statin therapy, he was able to reduce his overall cardiovascular risk, and his LDL cholesterol level dropped to just 20 mg/dL.
 

A Role for Aspirin?

However, one debate that has been rolling on in recent months is whether to start patients with elevated Lp(a) on low-dose aspirin.

It gained added momentum when Pablo Corral, MD, a lipidologist and a professor in the School of Medicine, Pharmacology Department, FASTA University, Mar del Plata, Buenos Aires, Argentina, highlighted the issue on X.

He pointed to a recent study, which showed that regular aspirin use was associated with a significantly lower rate of ASCVD mortality in adults without clinical ASCVD but who had elevated Lp(a).

Dr. Nicholls said that, when you “peel away the layers” of the current evidence, there is some suggestion that Lp(a)may be prothrombotic. “So in theory, perhaps aspirin might be maybe more intuitively useful there.”

He noted that the ASPREE primary prevention study found that low-dose aspirin in older adults resulted in a significantly higher risk for major hemorrhage over placebo and did not significantly reduce the risk for cardiovascular disease.

But an analysis he and his colleagues did suggest that aspirin may indeed benefit older individuals if they have elevated Lp(a) genotypes.
 

An Individual Decision

For Dr. Kronenberg and Dr. Laufs, there is currently a lack of appropriate data to make a recommendation either way, particularly for primary prevention.

They warned that the risk for thrombosis in patients with mildly elevated Lp(a) cannot be discounted, and in most cases either “the existing risk of bleeding exceeds the beneficial effects [of aspirin], or it’s not indicated,” said Dr. Laufs.

“When we make a recommendation, we should have evidence-based data,” Dr. Kronenberg said, but, at the moment, people “somehow put their finger in the air and see” which way the wind is blowing.

Dr. Catapano urged patients to talk to their physician, as even low-dose aspirin is “very potent” at inhibiting platelets.

Dr. Gibson agreed, saying that he is in two minds, as the potential benefit has to be weighed against the bleeding risk.

He personally takes low-dose aspirin because “I know I have a low bleeding risk,” but it is a decision “that has to be taken individually between a patient and their physician.”

Dr. Gibson, Dr. Kronenberg, Dr. Nicholls, and Dr. Catapano all reported conflicts of interest with numerous pharmaceutical companies and organizations.

Should a patient with high lipoprotein (a), or Lp(a), be started on low-dose aspirin?

This is the conundrum facing many physicians and patients, but even getting to that point will require more availability and coverage of tests and a greater appreciation of the risk associated with Lp(a), said cardiologists.
 

Lp(a): The Silent Risk

On Lp(a) Awareness Day, C. Michael Gibson, MD, MA, CEO of the Baim Institute for Clinical Research, Boston, Massachusetts, and PERFUSE took the opportunity to talk about his experiences with testing on X.

The professor of medicine at Harvard Medical School, also in Boston, said he was surprised to find that he had a very high calcium score, despite a low-density lipoprotein (LDL) cholesterol level of just 70 mg/dL. Eventually, he found out that he had a “very, very high Lp(a),” which was particularly concerning because his grandfather died of a heart attack at 45 years of age.

But how much risk does that represent?

A 2022 consensus statement from the European Atherosclerosis Society (EAS) highlighted that epidemiologic and genetic studies “strongly support a causal and continuous association between Lp(a) concentration and cardiovascular outcomes,” even at very low LDL cholesterol levels.

This is because Lp(a) has proinflammatory and proatherosclerotic properties, and high levels are associated with both micro- and macrocalcification of the aortic valve.

My oldest daughter is at sleepaway camp for a couple of weeks, and the camp has a photographer who goes around all day taking pictures of the kids, which get uploaded to a private Facebook group. In the past, I would go online every day (or, okay, several times a day) and scroll through all those pictures looking for one that features my kid. 

I don’t have to do that anymore. This year, I simply uploaded a picture of my daughter to an app and artificial intelligence (AI) takes care of the rest, recognizing her face amidst the sea of smiling children, and flagging just those photos for me to peruse. It’s amazing, really. And a bit scary.

The fact that facial recognition has penetrated the summer camp market should tell you that the tech is truly ubiquitous. But today we’re going to think a bit more about what AI can do with a picture of your face, because the power of facial recognition is not just skin deep.

What’s got me hot and bothered about facial images is this paper, appearing in Cell Metabolism, which adds a new layer to the standard facial-analysis playbook: facial temperature.

To understand this paper, you need to understand a whole field of research that is developing various different “clocks” for age. 

It turns out that age really is just a number. Our cells, our proteins, our biochemistry can be analyzed to give different numbers. These “clocks,” as distinct from the calendar we usually use to measure our age, might have more predictive power than the number itself. 

There are numerous molecular clocks, such as telomere length, that not only correlate with calendar age but are superior to calendar age in predicting age-related complications. Testing telomere length typically requires a blood sample — and remains costly. But we can use other sources to estimate age; how about a photo?

I mean, we do this all the time when we meet someone new or, as a physician, when we meet a new patient. I have often written that a patient “appears younger than their stated age,” and we’ve all had the experience of hearing how old someone is and being shocked. I mean, have you seen Sharon Stone recently? She’s 66 years old. Okay — to be fair, there might be some outside help there. But you get the point.

Back to the Cell Metabolism paper. Researchers report on multiple algorithms to obtain an “age” from a picture of an individual’s face. 

The first algorithm is pretty straightforward. Researchers collected 2811 images, all of Han Chinese individuals ranging in age from 20 to 90 years, and reconstructed a 3D facial map from those.

On any given day, oncologist Mark Lewis, MD, feels like he’s seesawing between two eras of technology. 

One minute, he’s working on sequencing a tumor genome. The next, he’s sifting through pages of disorganized data from a device that has been around for decades: the fax machine. 

“If two doctors’ offices aren’t on the same electronic medical record, one of the main ways to transfer records is still by fax,” said Dr. Lewis, director of gastrointestinal oncology at Intermountain Healthcare in Murray, Utah. “I can go from cutting-edge innovation to relying on, at best, 1980s information technology. It just boggles my mind.”

Dr. Lewis, who has posted about his frustration with fax machines, is far from alone. Oncologists are among the many specialists across the country at the mercy of telecopiers. 

According to a 2021 report by the Office of the National Coordinator for Health Information Technology, fax and mail continue to be the most common methods for hospitals and health systems to exchange care record summaries. In 2019, nearly 8 in 10 hospitals used mail or fax to send and receive health information, the report found. 

Fax machines are still commonplace across the healthcare spectrum, said Robert Havasy, MS, senior director for informatics strategy at the Healthcare Information and Management Systems Society (HIMSS). Inertia, cost, and more pressing priorities for hospitals and medical institutions contribute to the technology sticking around, he explained. 

“Post-COVID, my guess is we’re still at over 50% of healthcare practices using fax for some reason, on a daily basis,” Mr. Havasy said in an interview. “A lot of hospitals just don’t have the time, the money, or the staff to fix that problem because there’s always something a little higher up the priority chain they need to focus on.” 

If, for instance, “you’re going to do a process redesign to reduce hospital total acquired infections, your fax machine replacement might be 10th or 12th on the list. It just never gets up to 1 or 2 because it’s ‘not that much of a problem,’ ” he added.

Or is it?

Administrators may not view fax machines as a top concern, but clinicians who deal with the machines daily see it differently. 

“What worries me is we’re taking records out of an electronic storehouse [and] converting them to a paper medium,” Dr. Lewis said. “And then we are scanning into another electronic storehouse. The more steps, the more can be lost.”

And when information is lost, patient care can be compromised. 

Slower Workflows, Care Concerns

Although there are no published data on fax machine use in oncology specifically, this outdated technology does come into play in a variety of ways along the cancer care continuum. 

Radiation oncologist David R. Penberthy, MD, said patients often seek his cancer center’s expertise for second opinions, and that requires collecting patient records from many different practices. 

“Ideally, it would come electronically, but sometimes it does come by fax,” said Dr. Penberthy, program director of radiation oncology at the University of Virginia School of Medicine in Charlottesville. “The quality of the fax is not always the best. Sometimes it’s literally a fax of a fax. You’re reading something that’s very difficult to read.” 

Orders for new tests are also typically sent and received via fax temporarily while IT teams work to integrate them into the electronic health record (EHR), Dr. Penberthy said. 

Insurers and third-party laboratories often send test results back by fax as well.

“Even if I haven’t actually sent my patient out of our institution, this crucial result may only be entered back into the record as a scanned document from a fax, which is not great because it can get lost in the other results that are reported electronically,” Dr. Lewis said. The risk here is that an ordering physician won’t see these results, which can lead to delayed or overlooked care for patients, he explained.

“To me, it’s like a blind spot,” Dr. Lewis said. “Every time we use a fax, I see it actually as an opportunity for oversight and missed opportunity to collect data.”

Dr. Penberthy said faxing can slow things down at his practice, particularly if he faxes a document to another office but receives no confirmation and has to track down what happened. 

As for cybersecurity, data that are in transit during faxing are generally considered secure and compliant with the Health Insurance Portability and Accountability Act (HIPAA), said Mr. Havasy of HIMSS. However, the Privacy Rule also requires that data remain secure while at rest, which isn’t always possible, he added. 

“That’s where faxes fall down, because generally fax machines are in public, if you will, or open areas in a hospital,” he said. “They just sit on a desk. I don’t know that the next nurse who comes up and looks through that stack was the nurse who was treating the patient.” 

Important decisions or results can also be missed when sent by fax, creating headaches for physicians and care problems for patients. 

Dr. Lewis recently experienced an insurance-related fax mishap over Memorial Day weekend. He believed his patient had access to the antinausea medication he had prescribed. When Dr. Lewis happened to check the fax machine over the weekend, he found a coverage denial for the medication from the insurer but, at that point, had no recourse to appeal because it was a long holiday weekend. 

“Had the denial been sent by an electronic means that was quicker and more readily available, it would have been possible to appeal before the holiday weekend,” he said. 

Hematologist Aaron Goodman, MD, encountered a similar problem after an insurer denied coverage of an expensive cancer drug for a patient and faxed over its reason for the denial. Dr. Goodman was not directly notified that the information arrived and didn’t learn about the denial for a week, he said. 

“There’s no ‘ding’ in my inbox if something is faxed over and scanned,” said Dr. Goodman, associate professor of medicine at UC San Diego Health. “Once I realized it was denied, I was able to rectify it, but it wasted a week of a patient not getting a drug that I felt would be beneficial for them.”

Broader Health Policy Impacts

The use of outdated technology, such as fax machines, also creates ripple effects that burden the health system, health policy experts say. 

Duplicate testing and unnecessary care are top impacts, said Julia Adler-Milstein, PhD, professor of medicine and chief of the division of clinical informatics and digital transformation at the University of California, San Francisco.

Studies show that 20%-30% of the $65 billion spent annually on lab tests is used on unnecessary duplicate tests, and another estimated $30 billion is spent each year on unnecessary duplicate medical imaging. These duplicate tests may be mitigated if hospitals adopt certified EHR technology, research shows.

Still, without EHR interoperability between institutions, new providers may be unaware that tests or past labs for patients exist, leading to repeat tests, said Dr. Adler-Milstein, who researches health IT policy with a focus on EHRs. Patients can sometimes fill in the gaps, but not always. 

“Fax machines only help close information gaps if the clinician is aware of where to seek out the information and there is someone at the other organization to locate and transmit the information in a timely manner,” Dr. Adler-Milstein said. 

Old technology and poor interoperability also greatly affect data collection for disease surveillance and monitoring, said Janet Hamilton, MPH, executive director for the Council of State and Territorial Epidemiologists. This issue was keenly demonstrated during the pandemic, Ms. Hamilton said. 

“It was tragic, quite honestly,” she said. “There was such an immense amount of data that needed to be moved quickly, and that’s when computers are at their best.”

But, she said, “we didn’t have the level of systems in place to do it well.”

Specifically, the lack of electronic case reporting in place during the pandemic — where diagnoses are documented in the record and then immediately sent to the public health system — led to reports that were delayed, not made, or had missing or incomplete information, such as patients’ race and ethnicity or other health conditions, Ms. Hamilton said. 

Incomplete or missing data hampered the ability of public health officials and researchers to understand how the virus might affect different patients.

“If you had a chronic condition like cancer, you were less likely to have a positive outcome with COVID,” Ms. Hamilton said. “But because electronic case reporting was not in place, we didn’t get some of those additional pieces of information. We didn’t have people’s underlying oncology status to then say, ‘Here are individuals with these types of characteristics, and these are the things that happen if they also have a cancer.’” 

Slow, but Steady, Improvements

Efforts at the state and federal levels have targeted improved health information exchange, but progress takes time, Dr. Adler-Milstein said.

Most states have some form of health information exchange, such as statewide exchanges, regional health information organizations, or clinical data registries. Maryland is often held up as a notable example for its health information exchange, Dr. Adler-Milstein noted.

According to Maryland law, all hospitals under the jurisdiction of the Maryland Health Care Commission are required to electronically connect to the state-designated health information exchange. In 2012, Maryland became the first state to connect all its 46 acute care hospitals in the sharing of real-time data. 

The Health Information Technology for Economic and Clinical Health (HITECH) Act provided federal-enhanced Medicaid matching funds to states through 2021 to support efforts to advance electronic exchange. Nearly all states used these funds, and most have identified other sources to sustain the efforts, according to a recent US Government Accountability Office (GAO) report. However, GAO found that small and rural providers are less likely to have the financial and technological resources to participate in or maintain electronic exchange capabilities.

Nationally, several recent initiatives have targeted health data interoperability, including for cancer care. The Centers for Disease Control and Prevention’s Data Modernization Initiative is a multiyear, multi–billion-dollar effort to improve data sharing across the federal and state public health landscape. 

Meanwhile, in March 2024, the Biden-Harris administration launched United States Core Data for Interoperability Plus Cancer. The program will define a recommended minimum set of cancer-related data to be included in a patient’s EHR to enhance data exchange for research and clinical care. 

EHR vendors are also key to improving the landscape, said Dr. Adler-Milstein. Vendors such as Epic have developed strong sharing capabilities for transmitting health information from site to site, but of course, that only helps if providers have Epic, she said. 

“That’s where these national frameworks should help, because we don’t want it to break down by what EHR vendor you have,” she said. “It’s a patchwork. You can go to some places and hear success stories because they have Epic or a state health information exchange, but it’s very heterogeneous. In some places, they have nothing and are using a fax machine.”

Mr. Havasy believes fax machines will ultimately go extinct, particularly as a younger, more digitally savvy generation enters the healthcare workforce. He also foresees that the growing use of artificial intelligence will help eradicate the outdated technology. 

But, Ms. Hamilton noted, “unless we have consistent, ongoing, sustained funding, it is very hard to move off [an older] technology that can work. That’s one of the biggest barriers.” 

“Public health is about protecting the lives of every single person everywhere,” Ms. Hamilton said, “but when we don’t have the data that comes into the system, we can’t achieve our mission.”

Results from the latest survey by the National Comprehensive Cancer Network (NCCN) showed that numerous critical systemic anticancer therapies, primarily generic drugs, are currently in shortage.

Nearly 90% of the 28 NCCN member centers who responded to the survey, conducted between May 28 and June 11, said they were experiencing a shortage of at least one drug.

“Many drugs that are currently in shortage form the backbones of effective multiagent regimens across both curative and palliative treatment settings,” NCCN’s CEO Crystal S. Denlinger, MD, said in an interview.

The good news is that carboplatin and cisplatin shortages have fallen dramatically since 2023. At the peak of the shortage in 2023, 93% of centers surveyed reported experiencing a shortage of carboplatin and 70% were experiencing a shortage of cisplatin, whereas in 2024, only 11% reported a carboplatin shortage and 7% reported a cisplatin shortage.

“Thankfully, the shortages for carboplatin and cisplatin are mostly resolved at this time,” Dr. Denlinger said.

However, all three NCCN surveys conducted in the past year, including the most recent one, have found shortages of various chemotherapies and supportive care medications, which suggests this is an ongoing issue affecting a significant spectrum of generic drugs.

“The acute crisis associated with the shortage of carboplatin and cisplatin was a singular event that brought the issue into the national spotlight,” but it’s “important to note that the current broad drug shortages found on this survey are not new,” said Dr. Denlinger.

In the latest survey, 89% of NCCN centers continue to report shortages of one or more drugs, and 75% said they are experiencing shortages of two or more drugs.

Overall, 57% of centers are short on vinblastine, 46% are short on etoposide, and 43% are short on topotecan. Other common chemotherapy and supportive care agents in short supply include dacarbazine (18% of centers) as well as 5-fluorouracil (5-FU) and methotrexate (14% of centers).

In 2023, however, shortages of methotrexate and 5-FU were worse, with 67% of centers reporting shortages of methotrexate and 26% of 5-FU.

In the current survey, 75% of NCCN centers also noted they were aware of drug shortages within community practices in their area, and more than one in four centers reported treatment delays requiring additional prior authorization.

Cancer drug shortages impact not only routine treatments but also clinical trials. The recent survey found that 43% of respondents said drug shortages disrupted clinical trials at their center. The biggest issues centers flagged included greater administrative burdens, lower patient enrollment, and fewer open trials.

How are centers dealing with ongoing supply issues?

Top mitigation strategies include reducing waste, limiting use of current stock, and adjusting the timing and dosage within evidence-based ranges.

“The current situation underscores the need for sustainable, long-term solutions that ensure a stable supply of high-quality cancer medications,” Alyssa Schatz, MSW, NCCN senior director of policy and advocacy, said in a news release.

Three-quarters (75%) of survey respondents said they would like to see economic incentives put in place to encourage the high-quality manufacturing of medications, especially generic versions that are often in short supply. Nearly two-thirds (64%) cited a need for a broader buffer stock payment, and the same percentage would like to see more information on user experiences with various generic suppliers to help hospitals contract with those engaging in high-quality practices.

The NCCN also continues to work with federal regulators, agencies, and lawmakers to implement long-term solutions to cancer drug shortages.

“The federal government has a key role to play in addressing this issue,” Ms. Schatz said. “Establishing economic incentives, such as tax breaks or manufacturing grants for generic drugmakers, will help support a robust and resilient supply chain — ultimately safeguarding care for people with cancer across the country.”

Children with asthma who were insured by Medicaid were significantly less likely to receive specialist care over a 1-year period than children with private insurance, based on claims data from nearly 200,000 children.

Primary care clinicians successfully manage many children with asthma, but data on specialist care according to insurance coverage are lacking, wrote Kimberley H. Geissler, PhD, of the University of Massachusetts Chan Medical School–Baystate, Springfield, Massachusetts, and colleagues.

Despite many interventions over time, “low-income children insured by Medicaid, many of whom are from minoritized racial and ethnic groups, continue to have worse outcomes and higher rates of poorly controlled asthma than children who are privately insured,” Dr. Geissler said in an interview.

“Because differences in whether a child sees an asthma specialist could contribute to these disparities, better understanding specialist use among both groups of kids may help inform potential solutions,” she said.

In a study published in JAMA Network Open, the researchers identified children with asthma aged 2-17 years using data from the Massachusetts All-Payer Claims Database for the years 2015-2020. The study population included 198,101 children and 432,455 child-year observations from children with asthma during a year when they met at least one of three criteria with any asthma diagnosis: One or more hospital visits, two or more outpatient visits, or at least one outpatient visit and at least one asthma medication.
 

Outpatient Visit Outcome

The primary outcome of asthma specialist care was defined as at least one outpatient visit with any asthma diagnosis to a clinician with a code of allergy and immunology, pulmonology, or otolaryngology.

A total of 66.2% of the child-year observations involved Medicaid and 33.8% involved private insurance. Approximately 15% of the children received asthma specialist care. However, nearly twice as many children with private insurance received asthma specialty care compared with those with Medicaid (20.6% vs 11.9%). In a full logistic regression analysis, children with Medicaid insurance were 55% less likely to receive asthma specialist treatment than children with private insurance.

Allergy and immunology was the most common specialty used, and the child-years for this specialty among children with Medicaid were less than half of those among children with private insurance (7.1% vs 15.9%).

Rates of persistent asthma were 20.0% and 16.9% in children with Medicaid and private insurance, respectively. Overall, children with persistent asthma were nearly four times as likely to receive asthma specialist care (adjusted odds ratio, 3.96). However, the difference in odds of receiving specialty care based on insurance type in favor of private insurance was greater among children with persistent asthma than among those without persistent asthma (−24.0 percentage points vs −20.8 percentage points).

The researchers found a similar pattern of difference in asthma specialty care in a sensitivity analysis limiting the results to child-year observations with at least one outpatient visit with any asthma diagnosis in a calendar year, although they also found a slight narrowing of the difference between the groups over time.

“Contrary to expectations, disparities in specialist care by insurance type were even more striking in children with persistent asthma,” the researchers wrote in their discussion. Notably, the growth of specialty drugs such as biologics for moderate to severe asthma are mainly prescribed by specialists, and ensuring access to specialists for children with Medicaid may reduce disparities in asthma control for those with severe or poorly controlled disease, they added.

The study findings were limited by several factors including the use only of data from Massachusetts, which may not generalize to other states, and the use of completed specialist visits without data on referrals, the researchers noted. Other limitations included a lack of data on asthma symptom frequency or control and on the setting in which an asthma diagnosis was made.

However, the results suggest a need for more attention to disparities in asthma care by insurance type, and more research is needed to determine whether these disparities persist in subsets of children with asthma, such as those with allergies or chronic medical conditions, they concluded.
 

Takeaways and Next Steps

“Perhaps unsurprisingly, children with private insurance were more likely to receive asthma specialist care than children with Medicaid,” Dr. Geissler told this news organization. The researchers expected a smaller gap between insurance types among children with persistent asthma, a marker for asthma severity, she said. However, “we found that the gap between those with Medicaid and those with private insurance is actually larger” for children with persistent asthma, she added.

As improved treatments for hard-to-control asthma become more available, pediatricians and primary care clinicians should follow the latest clinical guidelines for referring children to specialists for asthma care, said Dr. Geissler.

“Additionally, asthma specialists should ensure that their practices are accessible to children with Medicaid, as these families may face higher barriers to care; for example, transportation needs or scheduling challenges,” she said. Other strategies to overcome barriers to care might include electronic consultations with specialists or primary care–oriented interdisciplinary asthma clinics, which may be useful for all children with asthma but may particularly benefit those insured by Medicaid, she noted.

“Based on data limitations, we could not examine why we observed such big differences in specialist use by insurance type; for example, whether pediatricians were referring to specialists less for Medicaid-insured kids, or whether kids with Medicaid were less likely to see a specialist after a referral was made,” Dr. Geissler said. More research is needed to examine not only these factors but also the appropriateness of specialty care based on clinical guidelines to ensure high-quality evidence-based care for children with asthma who are insured by Medicaid, she said.

Asthma is a chronic and prevalent disease and requires a comprehensive approach that sometimes calls for specialist care, Anne Coates, MD, a pediatric pulmonologist in Portland, Maine, said in an interview.

Dr. Coates said she was surprised by the results of the current study but commended the authors for highlighting the limitations of the study, which illustrate areas for additional research. Notably, “the authors couldn’t observe referrals to specialists from primary care physicians; they used completed visits as a proxy,” Dr. Coates said.

More studies are needed to assess the completion of referral visits regardless of children’s insurance in order to better understand and address the barriers to specialty care, she added.

The current study is important because of the extent of asthma coupled with the significant number of children across the United States who are insured by Medicaid, especially underserved populations, she said.

“The burden of asthma differentially affects people of color who are living in lower resourced areas, and it is important in further research to understanding the barriers to helping people get the care they need,” Dr. Coates told this news organization. Some alternatives might include telehealth visits or even a hybrid visit to a primary care provider (PCP) who has high-speed internet, and the specialist could then conduct a telehealth visit from the PCP’s office, with the PCP acting as on-site eyes and ears, said Dr. Coates, who has used this strategy in her practice in Maine, where many patients live far from specialist care.

The study was supported by the National Heart, Lung, and Blood Institute and the University of Massachusetts Center for Clinical and Translational Science-Biostatistics, Epidemiology & Research Design Component. Dr. Geissler and Dr. Coates had no financial conflicts to disclose.

Analysis of finger sweat detected isoniazid in adults with tuberculosis (TB) for ≤ 6 hours after administration, based on data from a new pilot study.

Risk factors for TB treatment failure include poor medication compliance and insufficient exposure to medications, but measurement of drugs in samples of blood, saliva, or sweat can help assess adherence and inform dose adjustments, Katherine Longman, a PhD student at the University of Surrey, Guildford, England, and colleagues wrote.

Although TB is treatable, “it is well known that insufficient drug dosing leads to treatment failure and drug resistance, and so ensuring that patients have sufficient drug exposure is important,” said corresponding author Melanie J. Bailey, PhD, also of the University of Surrey.

“This can be carried out using blood, but blood is painful to collect and difficult to transport. Finger sweat offers a completely noninvasive way to sample patients,” but its use to determine medication adherence has not been examined, she said.

In a pilot study published in the International Journal of Antimicrobial Agents, the researchers reviewed data from 10 adults with TB who provided finger sweat, blood, and saliva samples at several time points ≤ 6 hours after receiving a controlled dose of isoniazid (median of 300 mg daily). They used liquid chromatography–mass spectrometry to examine the samples.

Overall, “isoniazid and acetyl isoniazid were detected in at least one finger sweat sample from all patients,” with detection rates of 96% and 77%, respectively, the researchers wrote. Given the short half-life of isoniazid, they used a window of 1-6 hours after administration. Isoniazid was consistently detected between 1 and 6 hours after administration, while acetyl isoniazid had a noticeably higher detection rate at 6 hours.

The researchers also examined creatinine to account for variability in volume of sweat samples, and found that finger sweat was significantly correlated to isoniazid concentration. The maximum isoniazid to creatinine ratio in finger sweat occurred mainly in the first hour after drug administration, and the activity of isoniazid in finger sweat over time reflected isoniazid concentration in serum more closely after normalization to creatinine, they said. The Pearson’s correlation coefficient (r) was 0.98 (P < .001; one-tailed), with normalization to creatinine, compared with r = 0.52 without normalization (P = .051).

The study findings were limited by several factors including the lack of knowledge of the last drug dose and lack of confirmation testing with an established method of analysis, the researchers noted. However, the results support the potential of the finger sweat test as a screening tool to indicate patients’ nonadherence or to identify patients at risk of low medication exposure.

“We were surprised that we were able to detect the drug in so many patient samples because the sample volume is so low, and so detection is challenging,” said Dr. Bailey. “We were also surprised that fingerprint and drug levels correlated so well after normalizing to creatinine. This is exciting as it unlocks the possibility to test drug levels, as well as providing a yes/no test.”

In practice, the finger sweat technique could reduce the burden on clinics by offering a completely noninvasive way to test a patient’s medication adherence. Looking ahead, more research is needed to explore whether creatinine normalization is widely applicable, such as whether it works for patients with abnormal kidney function, she added.
 

Noninvasive Option May Mitigate Treatment Challenges

The current study presents a strategy that might address current limitations in TB management, said Krishna Thavarajah, MD, a pulmonologist and director of the interstitial lung disease program at Henry Ford Hospital, Detroit, Michigan, in an interview.

Both self-administered treatment and directly observed therapy (DOT) for TB therapy have limitations, including adherence as low as 50% for TB regimens, she said. In addition, “DOT availability and efficacy can be limited by cost, personnel availability from an administration perspective, and by distrust of those being treated.”

In the current study, “I was struck by the correlation between the sweat and serum values of [isoniazid] and by the level of sophistication of noninvasive testing, being able to normalize for creatinine to account for different volumes of sweat,” said Dr. Thavarajah. In clinical practice, finger sweat isoniazid could potentially serve as an adjunct or alternative to DOT in patients with TB.

Although adherence to the sampling protocol and possible patient distrust of the process (such as concerns over what else is being collected in their sweat) might be barriers to the use of a finger sweat strategy in the clinical setting, appropriate patient selection, patient training, and encouraging clinicians to incorporate this testing into practice could overcome these barriers, said Dr. Thavarajah.

However, more research is needed to study the finger sweat strategy in larger, real-world samples and to study accuracy and treatment adherence with monitoring in a population undergoing DOT, she said.

The study was supported by the Engineering & Physical Sciences Research Council and by Santander PhD Mobility Awards 2019. The researchers had no financial conflicts to disclose. Dr. Thavarajah had no financial conflicts to disclose.

Analysis of finger sweat detected isoniazid in adults with tuberculosis (TB) for ≤ 6 hours after administration, based on data from a new pilot study.

Risk factors for TB treatment failure include poor medication compliance and insufficient exposure to medications, but measurement of drugs in samples of blood, saliva, or sweat can help assess adherence and inform dose adjustments, Katherine Longman, a PhD student at the University of Surrey, Guildford, England, and colleagues wrote.

Although TB is treatable, “it is well known that insufficient drug dosing leads to treatment failure and drug resistance, and so ensuring that patients have sufficient drug exposure is important,” said corresponding author Melanie J. Bailey, PhD, also of the University of Surrey.

“This can be carried out using blood, but blood is painful to collect and difficult to transport. Finger sweat offers a completely noninvasive way to sample patients,” but its use to determine medication adherence has not been examined, she said.

In a pilot study published in the International Journal of Antimicrobial Agents, the researchers reviewed data from 10 adults with TB who provided finger sweat, blood, and saliva samples at several time points ≤ 6 hours after receiving a controlled dose of isoniazid (median of 300 mg daily). They used liquid chromatography–mass spectrometry to examine the samples.

Overall, “isoniazid and acetyl isoniazid were detected in at least one finger sweat sample from all patients,” with detection rates of 96% and 77%, respectively, the researchers wrote. Given the short half-life of isoniazid, they used a window of 1-6 hours after administration. Isoniazid was consistently detected between 1 and 6 hours after administration, while acetyl isoniazid had a noticeably higher detection rate at 6 hours.

The researchers also examined creatinine to account for variability in volume of sweat samples, and found that finger sweat was significantly correlated to isoniazid concentration. The maximum isoniazid to creatinine ratio in finger sweat occurred mainly in the first hour after drug administration, and the activity of isoniazid in finger sweat over time reflected isoniazid concentration in serum more closely after normalization to creatinine, they said. The Pearson’s correlation coefficient (r) was 0.98 (P < .001; one-tailed), with normalization to creatinine, compared with r = 0.52 without normalization (P = .051).

LYON, FRANCE — The anti-obesity drug semaglutide is associated with significant reductions in the inflammatory marker high-sensitivity C-reactive protein (CRP), even in patients who do not lose substantial amounts of weight with the drug, according to data from the SELECT clinical trial.

The research, presented at the European Atherosclerosis Society 2024, involved over 17,600 patients with overweight or obesity and had established cardiovascular disease but not diabetes.

Those given semaglutide experienced a 38% reduction in high-sensitivity CRP levels compared with placebo regardless of baseline body mass index, statin use, cholesterol levels, and other measures.

“Weight loss was associated with greater high-sensitivity CRP reduction in both treatment groups,” said study presenter Jorge Plutzky, MD, director of Preventive Cardiology at Brigham and Women’s Hospital, Boston, but “with increased high-sensitivity CRP reductions in those receiving semaglutide.”

The drug also “significantly reduced high-sensitivity CRP early,” he said, “prior to major weight loss and in those who did not lose significant amounts of weight.” The reductions reached approximately 12% at 4 weeks and around 20% at 8 weeks, when the weight loss “was still quite modest,” at 2% and 3% of body weight, respectively. Even among patients who achieved weight loss of less than 2% body weight, semaglutide was associated with a reduction in high-sensitivity CRP levels.

In the SELECT trial, semaglutide also resulted in a consistent reduction of around 20% vs placebo in major adverse cardiovascular events such as cardiovascular mortality, nonfatal myocardial infarction, or nonfatal stroke.

But Naveed Sattar, MD, PhD, professor of cardiometabolic medicine at the University of Glasgow, Scotland, said in an interview that body weight “is probably the major driver” of CRP levels in the population, accounting for between 20% and 30% of the variation.

Dr. Sattar, who was not involved in the study, said that because drugs like semaglutide lower weight but also have anti-inflammatory effects, the question becomes: “Could the anti-inflammatory effects be part of the mechanisms by which these drugs affect the risk of major adverse cardiovascular events?”
 

Reducing Cardiovascular Events

The current analysis, however, cannot answer the question, he said. “All it tells us is about associations.”

“What we do know is semaglutide, predominantly by lowering weight, is lowering CRP levels and equally, we know that when you lose weight, you improve blood pressure, you improve lipids, and you reduce the risk of diabetes,” he said.

Dr. Sattar also took issue with the researchers’ conclusion that the high-sensitivity CRP reductions seen in SELECT occurred prior to major weight loss because the “pattern of CRP reduction and weight reduction is almost identical.”

Dr. Sattar also pointed out in a recent editorial that the drug appears to have a direct effect on blood vessels and the heart, which may lead to improvements in systemic inflammation. Consequently, he said, any assertion that semaglutide is genuinely anti-inflammatory is, at this stage, “speculation.”

Dr. Plutzky said that “systemic, chronic inflammation is implicated as a potential mechanism and therapeutic target in atherosclerosis and major adverse cardiovascular events, as well as obesity,” and high-sensitivity CRP levels are an “established biomarker of inflammation and have been shown to predict cardiovascular risk.”

However, the relationship between high-sensitivity CRP, responses to glucagon-like peptide 1 receptor agonists like semaglutide, and cardiovascular outcomes in obesity “remains incompletely understood,” said Dr. Plutzky.

Interventional Procedures Section

More than 1.5 million Americans are diagnosed with an incidental CT scan-detected lung nodule annually. Advanced bronchoscopy, as a diagnostic tool for evaluation of these nodules, has evolved rapidly, incorporating a range of techniques and tools beyond CT scan-guided biopsies to assess peripheral lesions. The primary goal is to provide patients with accurate benign or malignant diagnoses. However, accurately determining the effectiveness of innovative technologies in providing a diagnosis remains challenging, in part due to limitations in study design and outcome reporting, along with the scarcity of comparative and randomized controlled studies.^1,2 Current literature shows significant variability in diagnostic yield definition, lacking generalizability.

To address this issue, an official research statement by the American Thoracic Society and CHEST defines the diagnostic yield as “the proportion of all individuals undergoing the diagnostic procedure under evaluation in whom a specific malignant or benign diagnosis is established.”³ To achieve this measure, the numerator includes all patients with lung nodules in whom the result of a diagnostic procedure establishes a specific benign or malignant diagnosis that is readily sufficient to inform patient care without additional diagnostic workup, and the denominator should include all patients in whom the procedure was attempted or performed. This standardized definition is crucial for ensuring consistency across studies, allowing for comparison or pooling of results, enhancing the reliability of diagnostic yield data, and informing clinical decisions.
