The American College of Chest Physicians (CHEST), the American Thoracic Society, and the American Lung Association are pleased to announce that they are partnering to sponsor a scholar in pulmonary and critical care medicine in the prestigious Harold Amos Medical Faculty Development Program (AMFDP), a Robert Wood Johnson Foundation initiative.

Developed to increase the pool of applicants from historically marginalized backgrounds pursuing careers in medicine, dentistry, or nursing, the AMFDP invites applicants to apply each year to help shape medicine into a more equitable, more accessible practice.

Together, CHEST, ATS, and American Lung Association will provide funding for awards of $420,000 over 4 years to support pulmonary/critical care medicine scholars.

“I am immensely proud to be leading an initiative that has continued to help shape the careers of so many physician-scientists in such a meaningful way,” said David Wilkes, MD, National Director of the Harold Amos Medical Faculty Development Program for the Robert Wood Johnson Foundation, and a member of ATS and CHEST. “That these three highly respected respiratory societies are joining efforts to help fulfill the AMFDP’s mission speaks volumes about their commitment as allies and influencers in the quest to eliminate lung health disparities. This is a model for other specialty societies to collaborate on addressing disparities.”

“In the context of an increasingly diverse population, it is more important than ever that our patients have confidence and trust in those who care for them, something that will be easier to develop as we diversify our workforce,” said CHEST President David Schulman, MD, MPH, FCCP. “CHEST is incredibly excited to be working with the American Lung Association, the American Thoracic Society, and the Harold Amos Medical Faculty Development Program to fund training for individuals who have been traditionally underrepresented in medicine as they pursue careers in pulmonary and critical care medicine.”

“Health equity is woven into the fabric of the ATS,” said ATS President Lynn Schnapp, MD, ATSF. “And, partnering with our peers in the pulmonary and critical care space is a wonderful opportunity to advance our shared goal of cultivating the next generation of leaders in health access and equity.”

“The American Lung Association has historically funded researchers at the beginning of their careers, helping to build the foundation for the next great group of leaders,” said Albert Rizzo, MD, Chief Medical Officer for the Lung Association. “It is critical to the advancement of lung health and the care of patients to have physicians and scientists from diverse backgrounds, so we are honored to provide support for these individuals and increase diversity in pulmonary medicine.”

The call for application is now open. To learn more and to apply go to rwjf.org.

Adults with a congenital heart defect (CHD) are at increased risk for serious illness and death when hospitalized with COVID-19, making vaccination and other preventive measures even important in this population, say researchers with the Centers for Disease Control and Prevention.

“We found that hospitalized patients with heart defects are up to twice as likely to have critical outcomes of COVID-19 illness (admission to the intensive care unit, use of a ventilator to help with breathing, or death) compared to hospitalized COVID-19 patients without heart defects,” Karrie Downing, MPH, epidemiologist, with the CDC’s National Center on Birth Defects and Developmental Disabilities, said in an interview.

“Additionally, we learned that people with hearts defects who were older or who also had other conditions like heart failure, pulmonary hypertension, Down syndrome, diabetes, or obesity were the most likely to have critical COVID-19 illness, but children and adults with heart defects without these other conditions were still at increased risk,” Ms. Downing said.

The message for health care providers is clear: “Encourage your patients with heart defects to get vaccinated and discuss with your patients the need for other preventive measures to avoid infection that may progress to severe COVID-19 illness,” Ms. Downing added.

The study was published online March 7, 2022, in Circulation.

The researchers analyzed data on 235,638 patients hospitalized with COVID-19 between March 2020 and January 2021, including 421 (0.2%) with CHD. Most CHD patients were older than 30 years (73%) and 61% were men, with 55% non-Hispanic white, 19% Hispanic and 16% non-Hispanic Black.

Overall, 68% of CHD patients had at least one comorbidity, as did 59% of patients without CHD.

Rates of ICU admission were higher in the CHD group (54% vs. 43%), as were rates of invasive mechanical ventilation (24% vs. 15%) and in-hospital death (11% vs. 7%).

After accounting for patient characteristics, ICU admission, invasive mechanical ventilation and death were more prevalent among COVID-19 patients with rather than without CHD, with adjusted prevalence ratios of 1.4, 1.8 and 2.0, respectively.

When stratified by high-risk characteristics, prevalence estimates for ICU admission, invasive mechanical ventilation and death remained higher among patients with COVID-19 and CHD across nearly all strata, including younger age groups and those without heart failure, pulmonary hypertension, Down syndrome, diabetes, or obesity, the researchers reported.

Ms. Downing said more work is needed to identify why the clinical course of COVID-19 disease results in admission to the ICU, the need for a ventilator, or death for some hospitalized patients with CHD and not for others.

“There could be a number of social, environmental, economic, medical, and genetic factors playing a role. But staying up to date with COVID-19 vaccines and following preventive measures for COVID-19 are effective ways to reduce the risk of severe illness from COVID-19,” Ms. Downing said.

The study had no specific funding. The authors reported no relevant disclosures.

Drink a day could age your brain

There are many things we can do daily to improve our health: Exercise, read a book, eat an apple (supposedly). Not drink a glass of red wine. Wait, not drink? That’s right. We were told that a glass of red wine each night was doing something good for our hearts, but it’s doing something bad to our brains: Aging them prematurely.

According to a recent study in Nature Communications, drinking half a pint of beer a day could age the brain of a 50-year-old by 6 months. A pint of beer equaled 2 years of aging and a pint and a half aged participants’ brains by 3.5 years.

Courtesy Debora Cartagena, USCDCP

Compared with people who didn’t drink, those who averaged about two pints of beer or two glasses of wine daily had brains aged 10 years older!

The researchers’ analysis included MRI scans of about 37,000 middle-aged men in the United Kingdom, along with their medical information and drinking habits, Everyday Health reported. They determined volume reductions in two parts of the brain potentially impacted by daily consumption of alcohol: White matter, which controls the senses and communication, and gray matter, which controls cognitive functions such as movement, emotions, and memories.

Normal brain aging is bad enough: Stuff like forgetting why we walked into the kitchen or having a word we want to use on the tips of our tongues. Who knew that happy hour could be speeding up the process?

A big dose of meta-cine

The metaverse is big news in the tech world. For those who are less technologically inclined or haven’t thrown a few hundred dollars at a clunky virtual reality headset, the metaverse is a vaguely defined artificial reality world, brought to you by Facebo-, excuse us, Meta, where you hang out with people using a virtual avatar and do various activities, all from the comfort of your own home.

Piqsels

That’s not the most helpful definition, if we’re being honest, and that’s partially because the metaverse, as it’s being pushed by companies such as Meta, is very new and kind of a Wild West. No one really knows what it’ll be used for, but that’s not going to stop big business from pushing to secure their own corners of a new and exciting market, and that brings us to CVS, which is looking to become the first pharmacy in the metaverse.

Specifically, the company is looking to provide the entirety of its health care services – nonemergency medical care, wellness programs, nutrition advice, and counseling – to the metaverse. That makes sense. Telemedicine has become big during the pandemic, and bringing that care to the metaverse could work. Probably overcomplicated, since the sort of person who couldn’t figure out a video call to a doctor probably won’t be spending much time in the metaverse, but hey, if they can make it work, more power to them.

Where things get a bit silly is the online store. CVS looking to sell not only NFTs (because of course it is), but also downloadable virtual goods, including “prescription drugs, health, wellness, beauty, and personal care products,” according to the company’s claim to the U.S. Patent Trade Office. What exactly is a downloadable virtual prescription drug? Excellent question. We’re picturing holographic meatloaf, but the true answer is bound to be sillier than anything SpongeBob and friends could conjure.

Hello friends. LOTME Sports welcomes you to the University of Toledo’s Glass Bowl for the wackiest virtual sporting event since Usain Bolt raced against a cheetah.

Frank_P_AJJ74/Pixabay

Hi, I’m Jim Nantz, and we’re here to witness the brainchild of Toledo physics professor Scott Lee, PhD, who posed an unusual question to his students: Is Usain Bolt faster than a 900-pound dinosaur?

Before we get started, though, I’ve got a quick question for my partner in today’s broadcast, Hall of Fame quarterback Peyton Manning: Why is someone who practices physics called a physicist when someone who practices medicine is known as a physician?

Jim, I’m prepared to talk about how Dr. Lee’s students used the concepts of 1D kinematics – displacement, speed, velocity, and acceleration – to determine if a Jamaican sprinter could beat Dilophosaurus wetherilli in a hypothetical race. Heck, it took me 2 days to be able to pronounce Dilophosaurus wetherilli. Don’t get me started on etymology.

Fair enough, my friend. What else can you tell us?

In his article in The Physics Teacher, Dr. Lee noted that recent musculoskeletal models of vertebrate animals have shown that a dinosaur like Dilophosaurus could run about as fast as Usain Bolt when he set the world record of 9.58 seconds for 100 meters in 2009. You might remember Dilophosaurus from “Jurassic Park.” It was the one that attacked the guy who played Newman on “Seinfeld.”

Fascinating stuff, Peyton, but it looks like the race is about to start. And they’re off! Newton’s second law, which says that acceleration is determined by a combination of mass and force, gives the smaller Bolt an early advantage. The dinosaur takes longer to reach maximum running velocity and crosses the line 2 seconds behind the world’s fastest human. Amazing!

Be sure to tune in again next week, when tennis legend Serena Williams takes the court against a hungry velociraptor.
 

Turning back the egg timer

The idea of getting older can be scary. Wouldn’t it be nice if we could reverse the aging process? Nice, sure, but not possible. Well, it may just be possible for women undergoing assisted reproductive treatment.

It’s generally known that oocytes accumulate DNA damage over time as well, hindering fertility, but a lab in Jerusalem has found a way to reverse the age of eggs.

If you’re wondering how on Earth that was possible, here’s how. Scientists from the Hebrew University of Jerusalem said that they found a previously unknown aging mechanism, which they were able to reverse using antiviral medications, they reported in Aging Cell.

The experiment started on mice eggs, but soon real human eggs were donated. After the procedure, the treated eggs appeared younger, with less of the DNA damage that comes from age. Sperm has not yet been used to test fertility so it is unclear if this will result in something game changing, but the investigators have high hopes.

“Many women are trying to get pregnant aged 40 or over, and we think this could actually increase their level of fertility,” senior investigator Michael Klutstein, PhD, told the Times of Israel. “Within 10 years, we hope to use antiviral drugs to increase fertility among older women.”

We’re counting on you, science! Do your thing!

For those who are less technologically inclined or haven’t thrown a few hundred dollars at a clunky virtual reality headset, the metaverse is a vaguely defined artificial reality world, brought to you by Facebo-, excuse us, Meta, where you hang out with people using a virtual avatar and do various activities, all from the comfort of your own home.

Piqsels

That’s not the most helpful definition, if we’re being honest, and that’s partially because the metaverse, as it’s being pushed by companies such as Meta, is very new and kind of a Wild West. No one really knows what it’ll be used for, but that’s not going to stop big business from pushing to secure their own corners of a new and exciting market, and that brings us to CVS, which is looking to become the first pharmacy in the metaverse.

Specifically, the company is looking to provide the entirety of its health care services – nonemergency medical care, wellness programs, nutrition advice, and counseling – to the metaverse. That makes sense. Telemedicine has become big during the pandemic, and bringing that care to the metaverse could work. Probably overcomplicated, since the sort of person who couldn’t figure out a video call to a doctor probably won’t be spending much time in the metaverse, but hey, if they can make it work, more power to them.

Where things get a bit silly is the online store. CVS looking to sell not only NFTs (because of course it is), but also downloadable virtual goods, including “prescription drugs, health, wellness, beauty, and personal care products,” according to the company’s claim to the U.S. Patent Trade Office. What exactly is a downloadable virtual prescription drug? Excellent question. We’re picturing holographic meatloaf, but the true answer is bound to be sillier than anything SpongeBob and friends could conjure.

Hello friends. LOTME Sports welcomes you to the University of Toledo’s Glass Bowl for the wackiest virtual sporting event since Usain Bolt raced against a cheetah.

Hi, I’m Jim Nantz, and we’re here to witness the brainchild of Toledo physics professor Scott Lee, PhD, who posed an unusual question to his students: Is Usain Bolt faster than a 900-pound dinosaur?

Before we get started, though, I’ve got a quick question for my partner in today’s broadcast, Hall of Fame quarterback Peyton Manning: Why is someone who practices physics called a physicist when someone who practices medicine is known as a physician?

Jim, I’m prepared to talk about how Dr. Lee’s students used the concepts of 1D kinematics – displacement, speed, velocity, and acceleration – to determine if a Jamaican sprinter could beat Dilophosaurus wetherilli in a hypothetical race. Heck, it took me 2 days to be able to pronounce Dilophosaurus wetherilli. Don’t get me started on etymology.

Fair enough, my friend. What else can you tell us?

In his article in The Physics Teacher, Dr. Lee noted that recent musculoskeletal models of vertebrate animals have shown that a dinosaur like Dilophosaurus could run about as fast as Usain Bolt when he set the world record of 9.58 seconds for 100 meters in 2009. You might remember Dilophosaurus from “Jurassic Park.” It was the one that attacked the guy who played Newman on “Seinfeld.”

Fascinating stuff, Peyton, but it looks like the race is about to start. And they’re off! Newton’s second law, which says that acceleration is determined by a combination of mass and force, gives the smaller Bolt an early advantage. The dinosaur takes longer to reach maximum running velocity and crosses the line 2 seconds behind the world’s fastest human. Amazing!

Be sure to tune in again next week, when tennis legend Serena Williams takes the court against a hungry velociraptor.
 

Turning back the egg timer

The idea of getting older can be scary. Wouldn’t it be nice if we could reverse the aging process? Nice, sure, but not possible. Well, it may just be possible for women undergoing assisted reproductive treatment.

It’s generally known that oocytes accumulate DNA damage over time as well, hindering fertility, but a lab in Jerusalem has found a way to reverse the age of eggs.

If you’re wondering how on Earth that was possible, here’s how. Scientists from the Hebrew University of Jerusalem said that they found a previously unknown aging mechanism, which they were able to reverse using antiviral medications, they reported in Aging Cell.

The experiment started on mice eggs, but soon real human eggs were donated. After the procedure, the treated eggs appeared younger, with less of the DNA damage that comes from age. Sperm has not yet been used to test fertility so it is unclear if this will result in something game changing, but the investigators have high hopes.

“Many women are trying to get pregnant aged 40 or over, and we think this could actually increase their level of fertility,” senior investigator Michael Klutstein, PhD, told the Times of Israel. “Within 10 years, we hope to use antiviral drugs to increase fertility among older women.”

We’re counting on you, science! Do your thing!

David Bennett Sr, the 57-year-old patient with terminal heart disease who became the first person to receive a genetically modified pig heart, has died. He passed away March 8, according to a statement from the University of Maryland Medical Center (UMMC), Baltimore, where the transplant was performed.

Mr. Bennett received the transplant on January 7 and lived for 2 months following the surgery.   

Although not providing the exact cause of his death, UMMC said Mr. Bennett’s condition began deteriorating several days before his death.

When it became clear that he would not recover, he was given compassionate palliative care and was able to communicate with his family during his final hours.

“We are devastated by the loss of Mr. Bennett. He proved to be a brave and noble patient who fought all the way to the end. We extend our sincerest condolences to his family,” Bartley P. Griffith, MD, who performed the transplant, said in the statement.

“We are grateful to Mr. Bennett for his unique and historic role in helping to contribute to a vast array of knowledge to the field of xenotransplantation,” added Muhammad M. Mohiuddin, MD, director of the cardiac xenotransplantation program at University of Maryland School of Medicine.

Before receiving the genetically modified pig heart, Mr. Bennett had required mechanical circulatory support to stay alive but was rejected for standard heart transplantation at UMMC and other centers. He was ineligible for an implanted ventricular assist device due to ventricular arrhythmias.

Following surgery, the transplanted pig heart performed well for several weeks without any signs of rejection. The patient was able to spend time with his family and participate in physical therapy to help regain strength.

“This organ transplant demonstrated for the first time that a genetically modified animal heart can function like a human heart without immediate rejection by the body,” UMMC said in a statement issued 3 days after the surgery.

Thanks to Mr. Bennett, “we have gained invaluable insights learning that the genetically modified pig heart can function well within the human body while the immune system is adequately suppressed,” said Dr. Mohiuddin. “We remain optimistic and plan on continuing our work in future clinical trials.”

The patient’s son, David Bennett Jr, said the family is “profoundly grateful for the life-extending opportunity” provided to his father by the “stellar team” at the University of Maryland School of Medicine and the University of Maryland Medical Center.

“We were able to spend some precious weeks together while he recovered from the transplant surgery, weeks we would not have had without this miraculous effort,” he said.

“We also hope that what was learned from his surgery will benefit future patients and hopefully, one day, end the organ shortage that costs so many lives each year,” he added.

Pseudomonas aeruginosa persisted in the airways of patients with chronic obstructive pulmonary disease (COPD), based on data from 23 patients over a 1-year period.

P. aeruginosa is cultured in as many as 20% of bacterial exacerbations and has been linked to increased morbidity and mortality in patients with COPD, wrote Josefin Eklöf, MD, of the University of Copenhagen and colleagues. However, its patterns and characteristics have not been well studied, and researchers proposed that P. aerunginosa persists in COPD patients in part because of genetic adaptations in the genes related to antibiotic resistance.

In a study published in Clinical Microbiology and Infection, the researchers identified 23 consecutive patients enrolled in an ongoing randomized clinical trial at four sites in Denmark between Jan. 2018 and Jan. 2020. Participants were randomized 1:1 to targeted antipseudomonal antibiotic treatment for 14 days (between visit day 1 and visit day 14) or no antipseudomonal treatment. Sputum samples were collected at baseline on day 1 and on days 14, 30, 60, 90, and 365.

The researchers sequenced isolates from 23 adult patients over 365 days of follow-up. The recurrence of P. aeruginosa occurred in 19 patients (83%) during this period. Ultimately, a total of 153 isolates were analyzed. The researchers found that each patient carried their own unique lineage, with the except of one patient in whom two distinct lineages were identified.

“Independent mutation of the same gene across multiple lineages may be the result of positive selection of adaptive mutations,” Dr. Eklöf and colleagues wrote. They found 38 genes for P. aeruginosa that were mutated in at least two lineages, which suggested adaptive mutations. Some of the more frequently mutated genes were those important to antibiotic resistance and chronic infections, the researchers said. Specifically, mutations occurred in 40 of 140 pathoadaptive genes, compared with 265 of 5,572 other genes (P < .001). In addition, the 24 total lineages carried 4-6 antibiotic resistance genes, and no evidence suggested that lineages acquired or lost these genes during carriage.

Overall, the results indicate that the recurrence of P. aeruginosa was caused by persistence of the same clonal lineage in each patient. “This pattern of persistence was associated with genetic adaptation related to phenotypes considered important for P. aeruginosa infections,” the researchers said.

The study findings were limited by the relatively small number of samples and isolates per sample, the follow-up of only 1 year, and the inability to account for mutations in the early stage because few patients were naive to P. aeruginosa at the start of the study, the researchers noted. However, the results were strengthened by the relatively large and well-defined study population and high rate of sampling compliance, they said.

Overall, “the findings warrant research to improve therapy, including trial data on possible clinical benefits of attempting antibiotic eradication of P. aeruginosa in this vulnerable group of patients,” they concluded.

The study was supported by the Independent Research Fund Denmark and the Research committee at Copenhagen University Hospital-Herlev and Gentofte Hospital. The researchers had no financial conflicts to disclose.

Computed tomographic angiography (CTA) appears preferable to standard cath-based angiography for the initial evaluation of most stable, intermediate-risk patients with angina-like symptoms, researchers say, based on their study conducted at centers across Europe.

Clinical outcomes over several years in the randomized trial – called DISCHARGE, with an enrollment of more than 3,500 – were statistically similar whether the patients were assigned to CTA or invasive coronary angiography (ICA) as their initial evaluation. Symptoms and quality-of-life measures were also similar.

But the patients assigned to the initial-CTA strategy, of whom fewer than a fourth went on to cardiac cath, showed far fewer procedure-related complications and less often went to coronary revascularization during the median follow-up of 3.5 years, the group reported March 4 in the New England Journal of Medicine.

Based on the findings, CTA “is a safe alternative to cardiac catheterization for patients with suspected CAD [coronary artery disease] that will likely change clinical practice worldwide by replacing invasive testing in patients with stable chest pain who can be expected to benefit” those with an intermediate pretest probability for obstructive disease, principal investigator Marc Dewey, MD, Charité – Universitätsmedizin Berlin, told this news organization.

None of the patient subgroups explored in the trial showed a significant clinical benefit from one strategy over the other, Dr. Dewey commented in an email.

The trial’s results don’t apply to patients unlike those entered, and in particular, he said, “ICA should remain the first test option in patients with high clinical pretest probability of obstructive CAD.”

Dr. Dewey is senior author on the study’s publication, which was timed to coincide with his presentation of the results at ECR 2022 Overture, an all-virtual scientific session of the European Congress of Radiology.

“This is the definitive study,” Matthew Budoff, MD, Lundquist Institute at Harbor-UCLA, Torrance, California, said in an interview. It suggests in a large population that the initial CTA strategy “is as good and maybe safer” in stable patients at intermediate risk compared with initial ICA. “I would say close to 75% or 80% of the patients that we see would fall into that range of risk” and be suitable for the testing algorithm used in the study, said Dr. Budoff, who was not part of the trial.

Invasive angiography would generally still be the initial approach for patients at greater than intermediate risk, such as those with breakthrough angina or electrocardiographic changes, he said. “I still think there’s a huge role for invasive angiography. It’s just a bit smaller now than it used to be for the lower-risk patient.”  

The DISCHARGE trial, agreed cardiothoracic radiology specialist Rozemarijn Vliegenthart, MD, PhD, University of Groningen, the Netherlands, “shows that in patients with intermediate pretest probability, CTA should be used as a gatekeeper before invasive coronary angiography, instead of directly referring for invasive coronary angiography.”

It shows that “a CT-first approach” is both safe and clinically effective and even a trend suggesting better clinical outcomes, compared with ICA. And it demonstrates that “still, many diagnostic invasive coronary angiographies are performed unnecessarily,” Dr. Vliegenthart said as the invited discussant following Dr. Dewey’s presentation.

DISCOVER is only the latest in a series of major studies to explore how CTA best fits in with ICA, stress imaging, and other tests for evaluating patients with chest pain. For example, “the PROMISE trial and the SCOT-HEART trial found that CT was as good as or even better than functional testing. DISCHARGE, I think, confirms the safety of the CT strategy” and reaffirms that it is “at least as good” as an ICA-first approach, cardiologist Klaus F. Kofoed, MD, PhD, DMSc, Rigshospitalet University of Copenhagen, said when co-presenting the trial’s results with Dr. Dewey.

“We can now say CT may be suitable in intermediate-risk patients referred for ICA, particularly those with a clinical constellation suggesting a higher event risk, with abnormal or inconclusive functional test results, or with persistent symptoms despite medical treatment,” said Dr. Kofoed, who is on the DISCOVER steering committee.

The trial’s 3,561 patients with stable chest pain – at 26 experienced centers in 16 countries – were randomly assigned to undergo CTA or ICA as their initial diagnostic imaging approach. Entry required them to be at intermediate risk, defined as an estimated 10% to 60% probability of having obstructive CAD. Of note, women made up about 56% of both groups.

Imaging was positive for obstructive disease in 26% of the 1,808 patients in the CTA group and in the same proportion of the 1,753 who were assigned to ICA. Nonobstructive CAD was identified in 36% and 22%, respectively.

Importantly, 404 (22.3%) patients in the CTA group then underwent ICA, which identified obstructive CAD in 293 (72.5%).

With a complete follow-up in about 99% of patients, the report notes, the rate of the primary endpoint of major adverse cardiac events, or MACE (cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) was 2.1% in the CTA group and in 3.0% in the ICA group. The adjusted hazard ratio of 0.70 (95% confidence interval, 0.46-1.07; P = .10) fell short of significance.

The corresponding HR for an “expanded primary outcome” that also included transient ischemic attack or major procedure-related complications was 0.60 (95% CI, 0.42-0.85) in favor of the CTA group.

As a “pragmatic trial,” DISCHARGE relied on clinically identified events for the endpoint assessments and did not require, for example, laboratory biomarker or neurologic imaging for confirmation, the report notes.

Major procedure-related complications during the initial management phase occurred in 0.5% of the CTA group, and 1.9% of those assigned to initial ICA (HR, 0.26; 95% CI, 0.13-0.55).

Coronary revascularization was less common in the CTA group during the trial’s follow-up, 14.2% versus 18.0% for those assigned to ICA (HR, 0.76; 95% CI, 0.65-0.90).

But the prevalences of angina during the final 4 weeks of follow-up, the group reported, were statistically similar at 8.8% and 7.5% for patients assigned to CTA and ICA, respectively.

The trial showed “no material difference” between the initial CTA versus ICA strategies for its MACE primary endpoint, observed Joseph Loscalzo, MD, PhD, Brigham and Women’s Hospital and Harvard Medical School, Boston, Mass., in an accompanying editorial.

“This result is probably a consequence of the lack of effect of revascularization on cardiovascular events among most patients with stable angina and the limited number of those with high-risk anatomy who would benefit from revascularization in the trial,” he writes.

That CTA was performed “significantly earlier than angiography, 3 days versus 12 days after enrollment,” may have led to earlier coronary revascularization in that group, and therefore is “a better outcome in patients whose anatomy would benefit from it.”

Dr. Loscalzo questioned several aspects of the trial design, which, for example, led to a more than 35% prevalence of patients with nonanginal chest pain among those randomized. Different criteria for classifying patients as “intermediate risk” might also have contributed to the fairly low prevalence of patients in either group ultimately identified with obstructive CAD, he proposes. That low prevalence “suggests that the overall trial population had a low risk of obstructive CAD rather than an intermediate risk.”

DISCHARGE was supported by grants from the European Union Seventh Framework Program, the Berlin Institute of Health, Rigshospitalet of the University of Copenhagen, the British Heart Foundation, and the German Research Foundation. Disclosures for the authors and editorialist are available at NEJM.org. Dr. Budoff has disclosed receiving grant support from General Electric.

With a complete follow-up in about 99% of patients, the report notes, the rate of the primary endpoint of major adverse cardiac events, or MACE (cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) was 2.1% in the CTA group and in 3.0% in the ICA group. The adjusted hazard ratio of 0.70 (95% confidence interval, 0.46-1.07; P = .10) fell short of significance.

The corresponding HR for an “expanded primary outcome” that also included transient ischemic attack or major procedure-related complications was 0.60 (95% CI, 0.42-0.85) in favor of the CTA group.

As a “pragmatic trial,” DISCHARGE relied on clinically identified events for the endpoint assessments and did not require, for example, laboratory biomarker or neurologic imaging for confirmation, the report notes.

Major procedure-related complications during the initial management phase occurred in 0.5% of the CTA group, and 1.9% of those assigned to initial ICA (HR, 0.26; 95% CI, 0.13-0.55).

Coronary revascularization was less common in the CTA group during the trial’s follow-up, 14.2% versus 18.0% for those assigned to ICA (HR, 0.76; 95% CI, 0.65-0.90).

But the prevalences of angina during the final 4 weeks of follow-up, the group reported, were statistically similar at 8.8% and 7.5% for patients assigned to CTA and ICA, respectively.

The trial showed “no material difference” between the initial CTA versus ICA strategies for its MACE primary endpoint, observed Joseph Loscalzo, MD, PhD, Brigham and Women’s Hospital and Harvard Medical School, Boston, Mass., in an accompanying editorial.

“This result is probably a consequence of the lack of effect of revascularization on cardiovascular events among most patients with stable angina and the limited number of those with high-risk anatomy who would benefit from revascularization in the trial,” he writes.

That CTA was performed “significantly earlier than angiography, 3 days versus 12 days after enrollment,” may have led to earlier coronary revascularization in that group, and therefore is “a better outcome in patients whose anatomy would benefit from it.”

Dr. Loscalzo questioned several aspects of the trial design, which, for example, led to a more than 35% prevalence of patients with nonanginal chest pain among those randomized. Different criteria for classifying patients as “intermediate risk” might also have contributed to the fairly low prevalence of patients in either group ultimately identified with obstructive CAD, he proposes. That low prevalence “suggests that the overall trial population had a low risk of obstructive CAD rather than an intermediate risk.”

Computed tomographic angiography (CTA) appears preferable to standard cath-based angiography for the initial evaluation of most stable, intermediate-risk patients with angina-like symptoms, researchers say, based on their study conducted at centers across Europe.

Clinical outcomes over several years in the randomized trial – called DISCHARGE, with an enrollment of more than 3,500 – were statistically similar whether the patients were assigned to CTA or invasive coronary angiography (ICA) as their initial evaluation. Symptoms and quality-of-life measures were also similar.

But the patients assigned to the initial-CTA strategy, of whom fewer than a fourth went on to cardiac cath, showed far fewer procedure-related complications and less often went to coronary revascularization during the median follow-up of 3.5 years, the group reported March 4 in the New England Journal of Medicine.

Based on the findings, CTA “is a safe alternative to cardiac catheterization for patients with suspected CAD [coronary artery disease] that will likely change clinical practice worldwide by replacing invasive testing in patients with stable chest pain who can be expected to benefit” those with an intermediate pretest probability for obstructive disease, principal investigator Marc Dewey, MD, Charité – Universitätsmedizin Berlin, told this news organization.

None of the patient subgroups explored in the trial showed a significant clinical benefit from one strategy over the other, Dr. Dewey commented in an email.

The trial’s results don’t apply to patients unlike those entered, and in particular, he said, “ICA should remain the first test option in patients with high clinical pretest probability of obstructive CAD.”

Dr. Dewey is senior author on the study’s publication, which was timed to coincide with his presentation of the results at ECR 2022 Overture, an all-virtual scientific session of the European Congress of Radiology.

“This is the definitive study,” Matthew Budoff, MD, Lundquist Institute at Harbor-UCLA, Torrance, California, said in an interview. It suggests in a large population that the initial CTA strategy “is as good and maybe safer” in stable patients at intermediate risk compared with initial ICA. “I would say close to 75% or 80% of the patients that we see would fall into that range of risk” and be suitable for the testing algorithm used in the study, said Dr. Budoff, who was not part of the trial.

Invasive angiography would generally still be the initial approach for patients at greater than intermediate risk, such as those with breakthrough angina or electrocardiographic changes, he said. “I still think there’s a huge role for invasive angiography. It’s just a bit smaller now than it used to be for the lower-risk patient.”  

The DISCHARGE trial, agreed cardiothoracic radiology specialist Rozemarijn Vliegenthart, MD, PhD, University of Groningen, the Netherlands, “shows that in patients with intermediate pretest probability, CTA should be used as a gatekeeper before invasive coronary angiography, instead of directly referring for invasive coronary angiography.”

It shows that “a CT-first approach” is both safe and clinically effective and even a trend suggesting better clinical outcomes, compared with ICA. And it demonstrates that “still, many diagnostic invasive coronary angiographies are performed unnecessarily,” Dr. Vliegenthart said as the invited discussant following Dr. Dewey’s presentation.

DISCOVER is only the latest in a series of major studies to explore how CTA best fits in with ICA, stress imaging, and other tests for evaluating patients with chest pain. For example, “the PROMISE trial and the SCOT-HEART trial found that CT was as good as or even better than functional testing. DISCHARGE, I think, confirms the safety of the CT strategy” and reaffirms that it is “at least as good” as an ICA-first approach, cardiologist Klaus F. Kofoed, MD, PhD, DMSc, Rigshospitalet University of Copenhagen, said when co-presenting the trial’s results with Dr. Dewey.

“We can now say CT may be suitable in intermediate-risk patients referred for ICA, particularly those with a clinical constellation suggesting a higher event risk, with abnormal or inconclusive functional test results, or with persistent symptoms despite medical treatment,” said Dr. Kofoed, who is on the DISCOVER steering committee.

The trial’s 3,561 patients with stable chest pain – at 26 experienced centers in 16 countries – were randomly assigned to undergo CTA or ICA as their initial diagnostic imaging approach. Entry required them to be at intermediate risk, defined as an estimated 10% to 60% probability of having obstructive CAD. Of note, women made up about 56% of both groups.

Imaging was positive for obstructive disease in 26% of the 1,808 patients in the CTA group and in the same proportion of the 1,753 who were assigned to ICA. Nonobstructive CAD was identified in 36% and 22%, respectively.

Importantly, 404 (22.3%) patients in the CTA group then underwent ICA, which identified obstructive CAD in 293 (72.5%).

New cases of COVID-19 in children continued their descent toward normalcy, falling below 100,000 in a week for the first time since early August 2021, according to the American Academy of Pediatrics and the Children’s Hospital Association.

The sixth consecutive week of declines saw just under 69,000 U.S. children test positive for COVID-19 from Feb. 25 to March 3, a drop of almost 46% from the previous week and 94% since the Omicron-fueled peak of 1.15 million during the week of Jan. 14-20, the AAP and CHA said in their weekly COVID report. The total number of child cases is 12.7 million since the pandemic began, with children representing 19% of all cases.

New admissions also stayed on a downward path, as the rate dropped to 0.24 per 100,000 children aged 0-17 years on March 5, a decline of nearly 81% since hitting 1.25 per 100,000 on Jan. 15. The latest 7-day average for daily admissions, 178 per day from Feb. 27 to March 5, was 29% lower than the previous week and almost 81% lower than the peak of 914 per day for Jan. 10-16, the Centers for Disease Control and Prevention reported.

The story is the same for emergency department visits with diagnosed COVID-19, which are reported as a percentage of all ED visits. On March 4, the 7-day average for children aged 0-11 years was 0.8%, compared with a high of 13.9% in mid-January, while 12- to 15-year-olds had dropped from 12.4% to 0.5% and 16- to 17-year-olds went from 12.6% down to 0.5%, the CDC said on its COVID Data Tracker.

Florida’s surgeon general says no to the vaccine

Vaccination, in the meantime, is struggling to maintain a foothold against the current of declining cases. Florida Surgeon General Joseph Ladapo said that “the Florida Department of Health is going to be the first state to officially recommend against the COVID-19 vaccines for healthy children,” NBC News reported March 7. With such a move, “Florida would become the first state to break from the CDC on vaccines for children,” CNN said in its report.

Vaccinations among children aged 5-11 years, which hit 1.6 million in 1 week shortly after emergency use was authorized in early November, declined quickly shorty thereafter and only rose slightly during the Omicron surge. Since mid-January, the number of children receiving an initial dose has declined for seven consecutive weeks and is now lower than ever, based on CDC data compiled by the AAP.

Just over one-third of children aged 5-11 have gotten at least one dose of COVID-19 vaccine, while 26.4% are fully vaccinated. Among children aged 12-17, just over two-thirds (67.8%) have received at least one dose, 57.8% have completed the vaccine regimen, and 21.9% have gotten a booster, the CDC reported.

As of March 2, “about 8.4 million children 12-17 have yet to receive their initial COVID-19 vaccine dose,” the AAP said. About 64,000 children aged 12-17 had received their first dose in the previous week, the group noted, which was the second-lowest weekly total since the vaccine was approved for children aged 12-15 in May of 2021.

Heavier smoking significantly increased mortality in adults with progressive fibrosing interstitial lung disease (PF-ILD), based on data from 377 individuals.

The negative impact of smoking on pulmonary diseases is well documented, but the specific impact on patients with PF-ILD has not been well studied, Mark Platenburg, MD, of St. Antonious Hospital, Nieuwegein, the Netherlands, and colleagues wrote in Respiratory Medicine .

“Patients with PF-ILD or IPF [idiopathic pulmonary fibrosis] are prone to early mortality, indicating a need for prognostic [bio]marker studies for precision medicine,” they said.

The researchers identified adults older than 18 years with PF-ILD who were diagnosed at a single center. All study participants had at least 10% fibrosis, and showed either a decline of at least 10% in forced vital capacity, a 5.0%-9.9% relative FVC decline plus progressive respiratory symptoms and/or an increase in extent of fibrosis on subsequent high-resolution (HRCT progression), or progressive respiratory symptoms and HRCT progression over 24 months after ILD diagnosis.

Pack-years of smoking was a prognostic variable; the researchers also compared median transplant-free survival in heavy smokers and mild to moderate smokers. They also investigated the association between smoking quantity and emphysema in the study population.

Overall, the increased risk for mortality was 11%, 22%, and 44% in patients with 10, 20, and 40 pack-years of smoking, respectively.

Both the unadjusted and adjusted hazard ratio for pack-years were significant (1.014, P < .001 and 1.011, P = .022, respectively).

The median transplant-free survival of ever-smokers versus never-smokers with PF-ILD was 3.3 years versus 4.8 years; median transplant-free survival was 3.0 years for heavy smokers and 3.8 years for mild to moderate smokers. Similarly, median survival was 4.2 years in never-smokers versus 3.0 years in former smokers.

Emphysema was significantly more comment in heavy smokers, compared with never smokers and mild to moderate smokers (P < .001 for both).

“We observed a gradual decrease in survival starting from never to mild-moderate and subsequent heavy smokers supporting our finding that [pack-years] is an independent predictor for mortality in PF-ILD,” the researchers wrote. “This is an important message that clinicians could convey to their ILD patients, but also to patients at-risk for ILD.”

The study findings were limited by several factors, mainly the retrospective design, incomplete data for some patients, and lack of data on comorbidities, the researchers noted. However, the results strengthen the evidence for the detrimental effect of heavy smoking in PF-ILD, they said. Consequently, “efforts to reduce pack-years in those with, and at risk for, PF-ILD may translate into a survival benefit and should have high priority in clinical practice.”

The study was supported by grants from ZonMw TopZorg Care and TZO. The researchers had no financial conflicts to disclose.
