Cancer loses … by a nose

Since the human nose is unpredictable at best, we’ve learned to rely on animals for our detailed nozzle needs. But researchers have found the next best thing to man’s best friend to accurately identify cancers.

A team at the University of Pennsylvania has developed an electronic olfaction, or “e-nose,” that has a 95% accuracy rate in distinguishing benign and malignant pancreatic and ovarian cancer cells from a single blood sample. How?

The e-nose system is equipped with nanosensors that are able to detect the volatile organic compounds (VOCs) emitted by cells in a blood sample. Not only does this create an opportunity for an easier, noninvasive screening practice, but it’s fast. The e-nose can distinguish VOCs from healthy to cancerous blood cells in 20 minutes or less and is just as effective in picking up on early- and late-stage cancers.

Do you think this is a (food) game?

Dieting and eating healthy is tough, even during the best of times, and it has not been the best of times. With all respect to Charles Dickens, it’s been the worst of times, full stop. Millions of people have spent the past year sitting around their homes doing nothing, and it’s only natural that many would let their discipline slide.

Naturally, the solution to unhealthy eating habits is to sit down and play with your phone. No, that’s not the joke, the Food Trainer app, available on all cellular devices near you, is designed to encourage healthy eating by turning it into a game of sorts. When users open the app, they’re presented with images of food, and they’re trained to tap on images of healthy food and pass on images of unhealthy ones. The process takes less than 5 minutes.

It sounds really simple, but in a study of more than 1,000 people, consumption of junk food fell by 1 point on an 8-point scale (ranging from four times per day to zero to one time per month), participants lost about half a kilogram (a little over one pound), and more healthy food was eaten. Those who used the app more regularly, along the lines of 10 times per month or more, saw greater benefits.

It’s time for a little mass kickin’

The universe, scientists tell us, is a big place. Really big. Chromosomes, scientists tell us, are small. Really small. But despite this very fundamental difference, the universe and chromosomes share a deep, dark secret: unexplained mass.

This being a medical publication, we’ll start with chromosomes. A group of researchers measured their mass with x-rays for the first time and found that “the 46 chromosomes in each of our cells weigh 242 picograms (trillionths of a gram). This is heavier than we would expect, and, if replicated, points to unexplained excess mass in chromosomes,” Ian K. Robinson, PhD, said in a written statement.

A photo finish for the Smart Toilet

We know that poop can tell us a lot about our health, but new research by scientists at Duke University is really on a roll. Their Smart Toilet has been created to help people keep an eye on their bowel health. The device takes pictures of poop after it is flushed and can tell whether the consistency is loose, bloody, or normal.

The Smart Toilet can really help people with issues such as irritable bowel syndrome and inflammatory bowel disease by helping them, and their doctors, keep tabs on their poop. “Typically, gastroenterologists have to rely on patient self-reported information about their stool to help determine the cause of their gastrointestinal health issues, which can be very unreliable,” study lead author Deborah Fisher said.

In 2018, when Naomi Osaka won the U.S. Open by defeating Serena Williams, the trophy ceremony was painful to watch.

Ms. Williams had argued with an umpire over a controversial call, and the ceremony began with the crowd booing. Ms. Osaka, the victor, cried while Ms. Williams comforted her and quietly assured Ms. Osaka that the crowd was not booing at her. When asked how her dream of playing against Ms. Williams compared with the reality, the new champion, looking anything but victorious, responded: “Umm, I’m gonna sort of defer from your question, I’m sorry. I know that everyone was cheering for her, and I’m sorry it had to end like this.”

It was hardly the joyous moment it should have been in this young tennis player’s life.

Ms. Osaka, now 23, entered this year’s French Open as the Women’s Tennis Association’s second-ranked player and as the highest-paid female athlete of all time. She is known for her support of Black Lives Matter. Ms. Osaka announced that she would not be attending press conferences in an Instagram post days before the competition began. “If the organizations think they can keep saying, ‘do press or you’re going to get fined,’ and continue to ignore the mental health of the athletes that are the centerpiece of their cooperation then I just gotta laugh,” Ms. Osaka posted.

She was fined $15,000 on Sunday, May 30, when she did not appear at a press conference after winning her first match. Officials noted that she would be subjected to higher fines and expulsion from the tournament if she did not attend the mandatory media briefings. On June 1, Ms. Osaka withdrew from the French Open and explained her reasons on Instagram in a post where she announced that she has been struggling with depression and social anxiety and did not mean to become a distraction for the competition.
 

Psychiatrists weigh in

Sue Kim, MD, a psychiatrist who both plays and watches tennis, brought up Ms. Osaka’s resignation for discussion on the Maryland Psychiatric Society’s listserv. “[Ms.] Osaka put out on social media her depression and wanted to have rules reviewed and revised by the governing body of tennis, for future occasions. I feel it is so unfortunate and unfair and I am interested in hearing your opinions.”

Yusuke Sagawa, MD, a psychiatrist and tennis fan, wrote in: “During the COVID-19 pandemic, I rekindled my interest in tennis and I followed what transpired this past weekend. Naomi Osaka is an exceptionally shy and introverted person. I have noted that her speech is somewhat akin to (for lack of a better term) ‘Valley Girl’ talk, and from reading comments on tennis-related blogs, it appears she has garnered a significant amount of hatred as a result. Most of it is along the lines of people feeling her shyness and modesty is simply a masquerade.

“I have also seen YouTube videos of her signing autographs for fans. She is cooperative and pleasant, but clearly uncomfortable around large groups of people.

“Having seen many press conferences after a match,” Dr. Sagawa continued, “tennis journalists have a penchant for asking questions that are either personal or seemingly an attempt to stir up acrimony amongst players. Whatever the case, I truly do believe that this is not some sort of ruse on her part, and I hope that people come to her defense. It is disturbing to hear the comments already coming out from the ‘big names’ in the sport that have mostly been nonsupportive. Fortunately, there have also been a number of her contemporaries who have expressed this support for her.”

In the days following Ms. Osaka’s departure from the French Open, the situation has become more complex. She is now the keystone for discussions of athletes and gender, race, power, mental illness, and the role of social media as it is used in these types of communications.

Maryland psychiatrist Erik Roskes, MD, wrote: “I have followed this story from a distance and what strikes me is the intermixing of athleticism – which is presumably why we watch sports – and entertainment, the money-making part of it. The athletes are both athletes and entertainers, and [Ms.] Osaka seems to be unable to fully fulfill the latter part due to her unique traits. But like many, I wonder what if this had been Michael Phelps? Is there a gender issue at play?”

Stephanie Durruthy, MD, added: “[Ms.] Osaka brings complexity to the mental health conversations. There is no one answer to her current plight, but her being a person of color cannot be minimized. She magnified the race conversation in tennis to a higher level.

“When she was new to the Grand Slam scene, her Haitian, Japanese, and Black heritage became an issue with unending curiosity.

“[Ms.] Osaka used her platform during the 2020 U.S. Open to single-handedly highlight Black Lives Matter,” Dr. Durruthy continued. “Afterward, the tennis fans could not avoid seeing her face mask. In each match, she displayed another mask depicting the name of those killed. She described on social media her fears of being a Black person in America. The biases of gender and race are well described in the sports world.”

Lindsay Crouse wrote June 1 in the New York Times: “When Naomi Osaka dropped out of the French Open, after declining to attend media interviews that she said could trigger her anxiety, she wasn’t just protecting her mental health. She was sending a message to the establishment of one of the world’s most elite sports: I will not be controlled. This was a power move – and it packed more punch coming from a young woman of color. When the system hasn’t historically stood for you, why sacrifice yourself to uphold it? Especially when you have the power to change it instead.”

Professional sports are grueling on athletes, both physically and mentally. People will speculate about Ms. Osaka’s motives for refusing to participate in the media briefings that are mandated by her contract. Some will see it as manipulative, others as the desire of a young woman struggling with anxiety and depression to push back against a system that makes few allowances for those who suffer. As psychiatrists, we see how crippling these illnesses can be and admire those who achieve at these superhuman levels, often at the expense of their own well-being.

Dr. Kim, who started the MPS listserv discussion, ended it with: “I feel bad if Naomi Osaka needs to play a mental ‘illness’ card, as opposed to mental ‘wellness’ card.”

Let’s hope that Ms. Osaka’s withdrawal from the French Open sparks more conversation about how to accommodate athletes as they endeavor to meet both the demands of their contracts and when it might be more appropriate to be flexible for those with individual struggles.

Although rates are generally low, interstitial lung disease (ILD) can occur at any point in the first year of treatment with trastuzumab deruxtecan (T-DXd) for HER2-positive metastatic breast cancer (MBC).

That’s according to a pooled analysis of three early clinical trials with the drug that was reported at the European Society for Medical Oncology (ESMO): Breast Cancer virtual meeting.

Over a 5-year analysis period, the rate of any grade of ILD was 15.5%. The majority (79%) of those events were grade 1 or 2, observed pulmonologist Charles A. Powell, MD, of Icahn School of Medicine at Mount Sinai in New York, who presented the findings.

Of the 245 patients who were included in the analysis, 38 had an ILD event deemed related to treatment. A respective 9 (3.7%) and 21 (8.6%) had events graded as 1 or 2, 1 patient each (0.4%) had a grade 3 or 4 event, and 6 (2.4%) patients had a grade 5 event.

The timing of the first identified ILD event varied from 1.1 months to 20.8 months, given a median of 5.6 months overall. “This highlights an opportunity for more timely detection of ILD,” Dr. Powell suggested. He added that in almost all (97%) cases, ILD occurred before 12 months and the risk may even decrease over time “suggesting that the risk is not cumulative.”

He cautioned, however: “It is important to note that this analysis is exploratory and hypothesis generating in nature.”
 

ILD occurs with other cancer drugs

ILD is not just associated with T-DXd treatment, said the invited discussant for the trial, Harold J. Burstein, MD, PhD, of the Dana-Farber Cancer Institute in Boston.

“It’s important for clinicians to remember that ILD/pneumonitis is an uncommon, but potentially very serious side effect that affects many breast cancer treatments,” he said.

That not only includes T-DXd, but other newer drugs such the cyclin dependent kinase (CDK) 4/6 inhibitors and immune checkpoint inhibitors, as well as other older more established drugs including taxanes, cyclophosphamide and even the mTOR inhibitor everolimus.

“Both clinicians and patients need to be aware of this risk. It’s part of the differential diagnosis for any patient who develops either ground glass changes or other infiltrates on a CT scan, or who has symptoms,” Dr. Burstein added.
 

Investigating ILD in T-DXd trials

T-DXd (Enhertu) is an anti-HER2-antibody drug conjugate that contains a humanized anti-HER2 IgG1 monoclonal antibody akin to trastuzumab that is linked to DXd, a topoisomerase I inhibitor that is a derivative of exatecan.

It has been approved for use in patients with HER2-positive metastatic breast cancer after two other HER2 treatments fail in the United States and Europe, and after chemotherapy in Japan, noted Dr. Powell. This is largely due to the results from the phase 2, open-label DESTINY-Breast01 trial.

“In breast cancer, T-DXd continues to demonstrate clinically meaningful efficacy with a median duration of response of more than 20 months in a heavily pretreated population,” he said. Objective response rates seen in the DESTINY-Breast01 trial were around 60%, and the median progression-free survival was a little over 19 months.

To look at the issue of drug-related ILD events in patients treated with T-DXd for HER2-positive MBC, an independent adjudication committee was formed to look at all the imaging and clinical data from the DESTINY-Breast01 trial and two single-arm phase 1 trials (NCT02564900 and NCT03383692).

In all, data on 245 patients who had been treated with T-DXd at the approved dose of 5.4 mg/kg in those trials between August 2015 and June 2020 were analyzed.
 

Dealing with lung toxicity

“We are getting new drugs to improve the treatment of cancer, but they always come with a price in terms of toxicity,” observed David Cameron, MD, professor of medical oncology at Edinburgh University in Scotland. Dr. Cameron chaired the session.

“Several measures were taken to identify and mitigate ILD,” across all the T-DXd studies, Dr. Powell explained. As well as the independent adjudication committee, available guidelines were followed and updated on how to diagnose and treat drug-induced lung injuries, and a “safe use” campaign was run in 2019.

Many patients in the early MBC studies were recruited before these measures were in place, such as the use of systemic steroids to manage low-grade events.

The bottom line, however, is that if a patient develops ILD then treatment should be stopped, Dr. Powell said. “Patients with grade 1 events may restart once the ILD has resolved, but those with grade 2 to 4 events must discontinue treatment.”

Dr. Powell concluded: “The overall clinical data support the positive risk-benefit profile of T-DXd. Phase 3 randomized controlled trials in breast cancer are ongoing.”
 

ILD also seen in monarchE trial with abemaciclib

Data on ILD events seen in the phase 3 monarchE trial were also reported separately at the ESMO Breast Cancer virtual meeting. The analysis population included 2,971 patients who had been treated with the CDK 4/6 inhibitor abemaciclib (Verzenio) together with endocrine therapy and 2,800 who had received endocrine therapy alone in the early-stage, adjuvant advanced breast cancer setting.

Most ILD (97%) events that occurred were single occurrences, with any grade of ILD occurring in a higher percentage of patients treated with abemaciclib with endocrine therapy than endocrine therapy alone (2.9% vs. 1.2%). Grade 3 events occurred in a respective 0.4% and 0.0% of patients.
 

So who’s at risk?

The risk factors for ILD and pneumonitis are not well characterized with either of the two drugs discussed, Dr. Burstein observed.

“In the abemaciclib experience, it looked like obesity might be a predisposing factor, with trastuzumab deruxtecan, it looked like patients of Asian ancestry were greater risk, but we need more data to really understand who’s at jeopardy.”

Dr. Burstein observed: “This is something patients need to be aware of as they’re contemplating this treatment.”

While data to prove the benefit of the drug need to mature, Dr. Burstein “would likely discontinue therapy” if a patient were to develop ILD or pneumonitis and treat accordingly.

As for T-DXd, he said: “It’s important that patients know that lung disease is a potentially severe side effect of treatment and that any respiratory symptoms need to be jumped on quickly.”

While prospective studies are now needed, and the phase 3 data should help to better understand the risk of ILD with T-DXd, Dr. Burstein believes it will be important to develop algorithms to ensure the safe administration of the drug.

These algorithms should include “appropriate surveillance and monitoring, especially as we think about trying to move this drug forward into the early stage setting where we’re using it in women who have favorable prognosis, and potentially curative situations for breast cancer.”

The trastuzumab deruxtecan trials were cosponsored by Daiichi Sankyo and AstraZeneca. The monarchE trial was supported by Eli Lilly.

Dr. Powell acknowledged receiving personal fees for acting as an advisory or consultant to both companies as well as to Voluntis. Dr. Burstein had nothing to disclose, and Dr. Cameron had no relevant financial interests in the data being presented.

Although rates are generally low, interstitial lung disease (ILD) can occur at any point in the first year of treatment with trastuzumab deruxtecan (T-DXd) for HER2-positive metastatic breast cancer (MBC).

That’s according to a pooled analysis of three early clinical trials with the drug that was reported at the European Society for Medical Oncology (ESMO): Breast Cancer virtual meeting.

Over a 5-year analysis period, the rate of any grade of ILD was 15.5%. The majority (79%) of those events were grade 1 or 2, observed pulmonologist Charles A. Powell, MD, of Icahn School of Medicine at Mount Sinai in New York, who presented the findings.

Of the 245 patients who were included in the analysis, 38 had an ILD event deemed related to treatment. A respective 9 (3.7%) and 21 (8.6%) had events graded as 1 or 2, 1 patient each (0.4%) had a grade 3 or 4 event, and 6 (2.4%) patients had a grade 5 event.

The timing of the first identified ILD event varied from 1.1 months to 20.8 months, given a median of 5.6 months overall. “This highlights an opportunity for more timely detection of ILD,” Dr. Powell suggested. He added that in almost all (97%) cases, ILD occurred before 12 months and the risk may even decrease over time “suggesting that the risk is not cumulative.”

He cautioned, however: “It is important to note that this analysis is exploratory and hypothesis generating in nature.”
 

ILD occurs with other cancer drugs

ILD is not just associated with T-DXd treatment, said the invited discussant for the trial, Harold J. Burstein, MD, PhD, of the Dana-Farber Cancer Institute in Boston.

“It’s important for clinicians to remember that ILD/pneumonitis is an uncommon, but potentially very serious side effect that affects many breast cancer treatments,” he said.

That not only includes T-DXd, but other newer drugs such the cyclin dependent kinase (CDK) 4/6 inhibitors and immune checkpoint inhibitors, as well as other older more established drugs including taxanes, cyclophosphamide and even the mTOR inhibitor everolimus.

“Both clinicians and patients need to be aware of this risk. It’s part of the differential diagnosis for any patient who develops either ground glass changes or other infiltrates on a CT scan, or who has symptoms,” Dr. Burstein added.
 

Investigating ILD in T-DXd trials

T-DXd (Enhertu) is an anti-HER2-antibody drug conjugate that contains a humanized anti-HER2 IgG1 monoclonal antibody akin to trastuzumab that is linked to DXd, a topoisomerase I inhibitor that is a derivative of exatecan.

It has been approved for use in patients with HER2-positive metastatic breast cancer after two other HER2 treatments fail in the United States and Europe, and after chemotherapy in Japan, noted Dr. Powell. This is largely due to the results from the phase 2, open-label DESTINY-Breast01 trial.

“In breast cancer, T-DXd continues to demonstrate clinically meaningful efficacy with a median duration of response of more than 20 months in a heavily pretreated population,” he said. Objective response rates seen in the DESTINY-Breast01 trial were around 60%, and the median progression-free survival was a little over 19 months.

To look at the issue of drug-related ILD events in patients treated with T-DXd for HER2-positive MBC, an independent adjudication committee was formed to look at all the imaging and clinical data from the DESTINY-Breast01 trial and two single-arm phase 1 trials (NCT02564900 and NCT03383692).

In all, data on 245 patients who had been treated with T-DXd at the approved dose of 5.4 mg/kg in those trials between August 2015 and June 2020 were analyzed.

To the Editor:

Urticarial vasculitis (UV) is a clinicopathologic entity. It manifests as an eruption of erythematous wheals that clinically resemble urticaria, but the lesions of UV last longer, may leave residual hyperpigmentation, and may or may not be pruritic.¹ Therapies most often employed include oral antihistamines and systemic immunosuppressant drugs such as corticosteroids, dapsone, colchicine, or hydroxychloroquine.² We present a woman with UV who successfully was treated with omalizumab.

A 49-year-old woman presented to our outpatient clinic with generalized pruritic skin rashes of 2 years’ duration. She also described swelling on the upper eyelids 2 times monthly. She used several antihistamines (up to 4 times daily) and was taking systemic corticosteroids and antidepressants. Physical examination revealed generalized erythematous and edematous papules and plaques on the trunk and extremities (Figure 1). At follow-up a few days later, we observed that the lesions were lasting for more than 24 hours, but there was no residual pigmentation. According to clinical concerns and the association with angioedema, we initially thought the diagnosis was chronic urticaria and angioedema. The patient had no extracutaneous manifestations such as fever, arthralgia, or lymphadenopathy. Routine laboratory examinations including antinuclear antibodies were within reference range. She had normal C3 and C4 levels and an elevated total IgE level (344 IU/mL [reference range, 0–170 IU/mL]). Because the IgE level was elevated and she had no response to the highest dosages of antihistamines, we decided to start omalizumab therapy. Prior to starting omalizumab, we performed a skin biopsy for histopathologic and direct immunofluorescence examinations for UV, as the duration of the lesions was more than 24 hours. Histopathologic examination revealed lymphocytes within the vessel wall and perivascular lymphocytic infiltration with eosinophils (Figure 2). On direct immunofluorescence, perivascular IgA deposition was observed (Figure 3). Histopathologic findings were associated with lymphocytic vasculitis. Systemic involvement was not detected on detailed laboratory and radiologic examinations.

After the first application of omalizumab, the lesions disappeared within a few days. She was treated with subcutaneous omalizumab 300 mg every 4 weeks for 6 months, and we did not observe any adverse effects related to the drug. There was no relapse after therapy cessation.

Omalizumab is a recombinant humanized anti-IgE monoclonal antibody that is approved by the US Food and Drug Administration for treatment of chronic idiopathic urticaria.^3-5 Studies have suggested that omalizumab might play an important role in the treatment of other potentially IgE-mediated disease processes including allergic asthma, atopic dermatitis, allergic rhinitis, nasal polyposis, and severe ocular allergies.⁶ The proposed mechanism of action of omalizumab includes reduction of free IgE through the reversible formation of tiny, biologically inert complexes; targeting IgE-expressing B cells; and inhibiting production of IgE. Because it reduces free IgE, omalizumab has been used in normal IgE or hyper-IgE situations. Omalizumab also induces eosinophil apoptosis; increases IL-2, IL-3, tumor necrosis factor α, and IFN-γ; and reduces IL-4.⁷ A number of off-label uses have been described such as atopic dermatitis, bullous pemphigoid, hyper-IgE syndrome, cutaneous mastocytosis, toxic epidermal necrolysis, and eosinophilic granulomatosis with polyangitis.⁸ There are no clinical studies of omalizumab for UV, and only a few case reports have shown that omalizumab also might be beneficial for this condition.^2-4 Diez et al⁴ reported 3 cases of women aged 28, 51, and 54 years with spontaneous chronic urticaria with autoimmune and pressure components as well as vasculitis whose symptoms completely improved after starting omalizumab. Kai et al³ successfully treated a patient with normocomplementemic UV with omalizumab and suggested that omalizumab markedly improved the patient’s quality of life with chronic urticaria and UV. Ghazanfar and Thomsen² reported the case of a 68-year-old man diagnosed with histopathologically confirmed leukocytoclastic vasculitis. He had used systemic corticosteroid therapy and dapsone without notable improvement. The patient was switched to subcutaneous omalizumab 300 mg once every 4 weeks; after 1 month, he observed complete remission of the UV and symptoms.²

Our case suggests that omalizumab has a beneficial effect on patients with UV. Omalizumab may be effective in UV through its reduction of IgE, as in chronic urticaria, and through downstream effects on cellular activation mechanisms (possibly a reduction in chemotaxis or immune complex formation). However, the mechanism of action of omalizumab for UV remains, in part, unresolved. It is not known whether omalizumab is efficacious against both normocomplementemic and hypocomplementemic UV. Further studies with a greater number of patients are needed to confirm the effects of omalizumab for vasculitic patients.

The U.S. Food and Drug Administration has expanded the indication for rimegepant (Nurtec ODT, Biohaven) to include prevention of migraine in adults. Last year, rimegepant became the first calcitonin gene-related peptide (CGRP) receptor antagonist, available in a fast-acting orally disintegrating tablet, to be approved for the acute treatment of migraine with or without aura in adults.

Rimegepant is currently the only migraine medication approved to both treat acute migraine attacks and help prevent future migraine attacks.

The new indication allows for use of rimegepant for preventive treatment in adults with episodic migraine (more than 15 migraine days per month). Rimegepant may be used for up to 18 doses per month, which includes both acute and preventive therapy.

In a phase 2/3 study, oral rimegepant was superior to placebo in reducing monthly migraine days. About half of adults who took rimegepant experienced a 50% or greater reduction in the number of days of moderate to severe migraines per month.

The most common adverse effects of rimegepant therapy were nausea (2.7%) and stomach pain or indigestion (2.4%).

The FDA approval of rimegepant for the preventive treatment of migraine, along with its acute treatment indication, is “one of the most ground-breaking things to happen to migraine treatment in my 40 years of practicing headache medicine,” Peter J. Goadsby, MD, PhD, an investigator in the prevention study, said in a company news release.   

“To have one medication patients can use to treat and prevent migraine will likely change the treatment paradigm for many of the millions of people who live with migraine,” said Dr. Goadsby, professor of neurology, University of California, Los Angeles and King’s College, London.

The U.S. Food and Drug Administration has expanded the indication for rimegepant (Nurtec ODT, Biohaven) to include prevention of migraine in adults. Last year, rimegepant became the first calcitonin gene-related peptide (CGRP) receptor antagonist, available in a fast-acting orally disintegrating tablet, to be approved for the acute treatment of migraine with or without aura in adults.

Rimegepant is currently the only migraine medication approved to both treat acute migraine attacks and help prevent future migraine attacks.

The new indication allows for use of rimegepant for preventive treatment in adults with episodic migraine (more than 15 migraine days per month). Rimegepant may be used for up to 18 doses per month, which includes both acute and preventive therapy.

Myocarditis is present in a small percentage of competitive athletes after COVID-19 infection, even in those without symptoms, new research suggests.

In a cohort study of 1,597 competitive collegiate athletes undergoing comprehensive cardiovascular testing in the United States, the prevalence of clinical myocarditis based on a symptom-based screening strategy was only 0.31%.

But screening with cardiac MRI increased the prevalence of clinical and subclinical myocarditis by a factor of 7.4, to 2.3%, the authors reported.

The findings are published online May 27, 2021, in JAMA Cardiology.

“It was the largest study to evaluate college athletes who have had COVID with extensive cardiac testing, including MRI, and this gave us a very objective look at the cardiac findings, as they were not purely based upon a subjective evaluation of symptoms,” lead investigator Curt J. Daniels, MD, professor at Ohio State University Wexner Medical Center, Columbus, said in an interview.

“Unfortunately, our study showed that athletes can be asymptomatic, or at least not report symptoms. This is a very subjective feature, and we don’t know if they don’t report symptoms because they didn’t want to get tested. That is why we took a very objective approach,” Dr. Daniels said.

The finding that more than half of the asymptomatic athletes had myocarditis, or as the investigators called it, “subclinical myocarditis,” was a surprise, he acknowledged.

“More than half of the athletes found to have myocarditis reported no symptoms, and yes, that was a surprise, because prior to this study, the protocols that had been published stated that you had to have symptoms to even enter into the protocol for cardiac MRI. But, as our ... paper shows, if we had followed that protocol, we only would have found about 5 cases of myocarditis, as opposed to the total of 37 we found with cardiac MRI,” Dr. Daniels said.

In October 2020, the American College of Cardiology’s Sports and Exercise Council recommended that cardiac MRI be limited to athletes who exhibited symptoms as part of their guide to ensuring a safe return to play.

As reported by this news organization the council recommended a tiered approach to screening based on the presence of symptoms, followed by electrocardiography, injury biomarkers, and echocardiography. Any abnormalities detected were to be further characterized by the selective use of cardiac MRI.

At the time, there were relatively few data to support the recommendations, and all stakeholders called for larger datasets to better drive informed recommendations in the future.

In the current study, Dr. Daniels and associates conducted comprehensive cardiac screening – including ECG, troponin testing, echocardiography, and cardiac MRI – of 1,597 college athlete survivors of COVID-19.

The athletes were part of the Big Ten athletic conference, which consists of 13 major American universities.

Cardiac MRI revealed that 37 (2.3%) of these athletes demonstrated diagnostic criteria for COVID-19 myocarditis; of these, 20 had no cardiovascular symptoms and had normal ECGs, echocardiography, and troponin test results.

“These patients would not have been identified without CMR imaging. If we were going according to the older protocol, we would not have made this discovery. Cardiac MRI is the most sensitive and specific test for myocardial inflammation, there is no argument about that,” Dr. Daniels said.

The catch is, cardiac MRI is expensive and often difficult to access, especially in remote, rural, or other underserviced areas.

“You can’t get an MRI for every person who has had COVID, it’s just not feasible,” Dr. Daniels said. “We are not advocating that everybody get an MRI. But we do hope that our study creates awareness among clinicians and athletes themselves that if you’ve had COVID, even if you’re asymptomatic, there may be some heart changes. So be aware when you start to exercise again, if you have any symptoms, pause and seek medical care.”
 

Kudos to the sports cardiology community

In an accompanying editorial, James E. Udelson, MD, Ethan J. Rowin, MD, and Barry J. Maron, MD, from the CardioVascular Center at Tufts Medical Center, Boston, applauded the sports cardiology community for its diligence in acquiring and publishing data about the post–COVID-19 prevalence of cardiac abnormalities in competitive athletes.

“It is a real tribute to the sports cardiology community. There has been an amazing growth of information, and they not only gathered this information, they analyzed and published it, starting out with a study of 29 or 30 athletes, and now thousands,” Dr. Udelson said in an interview.

At the start of the pandemic, it appeared that 15%-20% of athletes had myocarditis, and athletic conferences were discussing canceling sports events.

However, with greater numbers comes a more accurate picture of the extent of the problem.

“Once you get thousands of subjects in these studies, you can hone in on what the real number is, so now we understand that if you screen everybody with a cardiac MRI, 1%, 2%, or 3% will have some evidence of what looks like myocarditis,” he said.

Dr. Udelson agreed that doing cardiac imaging in everyone is not feasible.

“This study looked at a very large number of people who all had an MRI, but that doesn’t mean everyone should have them. If you just do an echo, an EKG, and a troponin test, and if everything is normal, which is kind of what current recommendations are, this paper tells us that we are going to miss one or two people out of a hundred, and that might be okay,” he said. “So, if you are at a huge university that has a large medical center and you want to screen all your athletes with MRI, great. But if you’re at a high school in a remote area, you know that the alternative, not having an MRI, isn’t so bad, either.”

Background: For patients receiving palliative care who develop respiratory distress, conventional oxygen therapy may not adequately relieve symptoms of dyspnea, and noninvasive ventilation may not promote comfort. Few randomized controlled trials have investigated the use of high-flow nasal cannula (HFNC) for treatment of palliative care patients who present to the hospital with respiratory distress.

Pericardial fat is associated with a heightened risk for heart failure, particularly in women, new research suggests.

In a prospective cohort study of nearly 7,000 individuals, excess pericardial fat was linked to a higher risk for heart failure, even after adjustment for established risk factors for heart failure.

Women with high pericardial fat volume (PFV), defined as more than 70 cm³ or 2.4 fluid ounces, had double the risk of developing heart failure. For men, high PFV, defined as more than 120 cm³ or 4.0 fluid ounces, was associated with a 50% increase in the risk for heart failure.

The findings were published in the Journal of the American College of Cardiology.

“People will ask why should they measure fat around the heart. Why can’t they just take the waist circumference or body mass index as a measure for increased risk?” lead author Satish Kenchaiah, MD, MPH, Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“Yet, when we adjusted for waist circumference, hip circumference, waist to hip ratio, and other known variables, pericardial fat was still associated with an increased risk of heart failure. This tells me that it is not just overall fat in the body but something about its location around the heart that is playing a role,” Dr. Kenchaiah said.

“Now that we have found an association between any amount of fat around the pericardium and heart failure, it gives us an impetus to build future research on identifying how exactly these fat deposits influence the development of cardiomyopathy,” he said.

Dr. Kenchaiah and colleagues investigated the association of pericardial fat with incident heart failure by examining chest CT scans from 6,785 participants (3,584 women and 3,201 men aged 45-84 years) in the Multi-Ethnic Study of Atherosclerosis.

The participants were from four different ethnic groups: 38% were White; 28% were Black, 22% were Hispanic, and 12% were Chinese American. They were recruited between July 17, 2000, and Aug. 31, 2002, from six communities in the United States: Baltimore and Baltimore County; Chicago; Forsyth County, N.C.; Los Angeles County northern Manhattan and the Bronx, New York; and St. Paul, Minn.

All participants were free of cardiovascular disease at baseline.

The researchers followed participants for more than 17 years. During this time, 385 (5.7%; 164 women and 221 men) developed newly diagnosed heart failure.

In women, the hazard ratio for every 42 cm³ increase in PFV was 1.44 (95% confidence interval, 1.21-1.71; P < .001). In men, the HR was 1.13 (95% CI, 1.01-1.27; P = .03).

High PVF conferred a twofold greater risk for heart failure in women (HR, 2.06; 95% CI, 1.48-2.87; P < .001) and a 53% higher risk in men (HR, 1.53; 95% CI, 1.13-2.07; P = .006).

These associations remained significant after further adjustment for circulating markers of systemic inflammation (that is, C-reactive protein and interleukin-6), and abdominal subcutaneous or visceral fat.

They also found that the heightened risk persisted, even after adjustment for established risk factors for heart failure, such as age, cigarette smoking, alcohol consumption, sedentary lifestyle, high blood pressure, high blood sugar, high cholesterol, and myocardial infarction.

Results were similar among all of the ethnic groups studied.
 

A surprise finding

“The most surprising part of this study was that the risk for heart failure with increased pericardial fat does not seem to be explained by obesity and systemic inflammation alone,” Andreas P. Kalogeropoulos, MD, MPH, PhD, Stony Brook (N.Y.) University, said in an interview.

“If pericardial fat was merely a proxy for increased visceral fat, one would expect the association of pericardial fat with heart failure risk to go away after factoring in abdominal CT findings, which was not the case here. Also, accounting for inflammatory markers did not change things dramatically. However, we need to be careful here, as abdominal CT scans have not been done simultaneously with the pericardial fat scans in the study,” said Dr. Kalogeropoulos, who coauthored an accompanying editorial with Michael E. Hall, MD, University of Mississippi Medical Center, Jackson.

The other striking finding, although not entirely surprising, was the stronger association of pericardial fat with heart failure risk in women, he noted.

“Although several clues have been reported pointing to women being more sensitive to the adverse cardiac effects of pericardial fat, this is the first large prospective study to connect the dots and show much higher risk in women in a convincing way. For the record, this is the first prospective study to show the connection between pericardial fat and heart failure risk altogether,” Dr. Kalogeropoulos said.

“Obviously, we need to do more work to see how we can use the important findings of Kenchaiah and colleagues to reduce risk for heart failure among patients with increased pericardial fat, especially women. For starters, we would need a way to identify these patients,” he said. “In this aspect, it is encouraging that pericardial fat can be measured in low-radiation CT scans, similar to those used for coronary calcium, and that automation technology to speed up pericardial fat measurements is already in the pipeline.

“The next step would be to see what kind of interventions would reduce risk for heart failure in these patients,” he added. “Weight loss would be an obvious thing, but novel agents with favorable cardiometabolic effects, like newer antidiabetic medications, are intriguing options, too.”

The study was supported by the National Heart, Lung, and Blood Institute and the National Institutes of Health. Dr. Kenchaiah and Dr. Kalogeropoulos reported no relevant financial relationships.

Pericardial fat is associated with a heightened risk for heart failure, particularly in women, new research suggests.

In a prospective cohort study of nearly 7,000 individuals, excess pericardial fat was linked to a higher risk for heart failure, even after adjustment for established risk factors for heart failure.

Women with high pericardial fat volume (PFV), defined as more than 70 cm³ or 2.4 fluid ounces, had double the risk of developing heart failure. For men, high PFV, defined as more than 120 cm³ or 4.0 fluid ounces, was associated with a 50% increase in the risk for heart failure.

The findings were published in the Journal of the American College of Cardiology.

“People will ask why should they measure fat around the heart. Why can’t they just take the waist circumference or body mass index as a measure for increased risk?” lead author Satish Kenchaiah, MD, MPH, Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“Yet, when we adjusted for waist circumference, hip circumference, waist to hip ratio, and other known variables, pericardial fat was still associated with an increased risk of heart failure. This tells me that it is not just overall fat in the body but something about its location around the heart that is playing a role,” Dr. Kenchaiah said.

“Now that we have found an association between any amount of fat around the pericardium and heart failure, it gives us an impetus to build future research on identifying how exactly these fat deposits influence the development of cardiomyopathy,” he said.

Dr. Kenchaiah and colleagues investigated the association of pericardial fat with incident heart failure by examining chest CT scans from 6,785 participants (3,584 women and 3,201 men aged 45-84 years) in the Multi-Ethnic Study of Atherosclerosis.

The participants were from four different ethnic groups: 38% were White; 28% were Black, 22% were Hispanic, and 12% were Chinese American. They were recruited between July 17, 2000, and Aug. 31, 2002, from six communities in the United States: Baltimore and Baltimore County; Chicago; Forsyth County, N.C.; Los Angeles County northern Manhattan and the Bronx, New York; and St. Paul, Minn.

All participants were free of cardiovascular disease at baseline.

The researchers followed participants for more than 17 years. During this time, 385 (5.7%; 164 women and 221 men) developed newly diagnosed heart failure.

In women, the hazard ratio for every 42 cm³ increase in PFV was 1.44 (95% confidence interval, 1.21-1.71; P < .001). In men, the HR was 1.13 (95% CI, 1.01-1.27; P = .03).

High PVF conferred a twofold greater risk for heart failure in women (HR, 2.06; 95% CI, 1.48-2.87; P < .001) and a 53% higher risk in men (HR, 1.53; 95% CI, 1.13-2.07; P = .006).

These associations remained significant after further adjustment for circulating markers of systemic inflammation (that is, C-reactive protein and interleukin-6), and abdominal subcutaneous or visceral fat.

They also found that the heightened risk persisted, even after adjustment for established risk factors for heart failure, such as age, cigarette smoking, alcohol consumption, sedentary lifestyle, high blood pressure, high blood sugar, high cholesterol, and myocardial infarction.

Results were similar among all of the ethnic groups studied.
 

A surprise finding

“The most surprising part of this study was that the risk for heart failure with increased pericardial fat does not seem to be explained by obesity and systemic inflammation alone,” Andreas P. Kalogeropoulos, MD, MPH, PhD, Stony Brook (N.Y.) University, said in an interview.

“If pericardial fat was merely a proxy for increased visceral fat, one would expect the association of pericardial fat with heart failure risk to go away after factoring in abdominal CT findings, which was not the case here. Also, accounting for inflammatory markers did not change things dramatically. However, we need to be careful here, as abdominal CT scans have not been done simultaneously with the pericardial fat scans in the study,” said Dr. Kalogeropoulos, who coauthored an accompanying editorial with Michael E. Hall, MD, University of Mississippi Medical Center, Jackson.

The other striking finding, although not entirely surprising, was the stronger association of pericardial fat with heart failure risk in women, he noted.

“Although several clues have been reported pointing to women being more sensitive to the adverse cardiac effects of pericardial fat, this is the first large prospective study to connect the dots and show much higher risk in women in a convincing way. For the record, this is the first prospective study to show the connection between pericardial fat and heart failure risk altogether,” Dr. Kalogeropoulos said.

“Obviously, we need to do more work to see how we can use the important findings of Kenchaiah and colleagues to reduce risk for heart failure among patients with increased pericardial fat, especially women. For starters, we would need a way to identify these patients,” he said. “In this aspect, it is encouraging that pericardial fat can be measured in low-radiation CT scans, similar to those used for coronary calcium, and that automation technology to speed up pericardial fat measurements is already in the pipeline.

“The next step would be to see what kind of interventions would reduce risk for heart failure in these patients,” he added. “Weight loss would be an obvious thing, but novel agents with favorable cardiometabolic effects, like newer antidiabetic medications, are intriguing options, too.”

A “smart toilet” in development uses artificial intelligence (AI) to scan stool for consistency and presence of blood – and early evidence suggests it is more accurate than patient self-reporting, a study reveals.

The remote, automated, real-time analysis and reporting increase the likelihood of physicians detecting gastrointestinal issues earlier, investigators reported.

In a proof-of-concept study, the smart toilet was 85% accurate in categorizing stool consistency as loose, normal, or constipated. The findings were presented at the annual Digestive Disease Week® (DDW).

“This study highlights a very innovative and practical tool that could have major implications for patients and clinicians alike,” Andrea Shin, MD, who was not affiliated with the research, said in an interview.

“Stool form or consistency and signs of bleeding are some of the most important pieces of clinical history when it comes to GI or bowel symptoms,” added Dr. Shin, assistant professor of medicine in the department of gastroenterology and hepatology at Indiana University, Indianapolis.
 

Image analysis

The researchers tested their AI algorithm on 3,328 images. They assessed photos from the Internet and some submitted anonymously by participants in the study.

Two gastroenterologists also rated a subset of 552 images. The physicians showed “satisfactory agreement” on interrater reliability (the extent to which two or more “raters” [for example, observers, examiners] agree), the investigators noted.

The smart toilet also was 76% accurate for gross blood detection.

“It’s objective and more accurate,” study author Sonia Grego, PhD, said in an interview. In contrast to asking patients to keep a bowel movement diary or recall the frequency and consistency of their stool over time, “the system does it for you,” she added.

“Our technology – by automating the image acquisition – removes the burden of having to track your pattern for weeks or months,” added Dr. Grego, founding director of the Duke Smart Toilet Lab at Duke University in Durham, N.C.

Information provided by patients “can have a big impact on decision-making,” Dr. Shin said. “For example, if I am talking to an individual who suffers from irritable bowel syndrome [IBS], I commonly ask them about how loose or watery and hard or formed their stool is, because this information gives me clues as to the underlying problems that may be driving their symptoms.”

Dr. Shin agreed it can be challenging for people to know what is important to report to their doctor. “This tool has the potential to relieve patient burden and facilitate communication between a patient and their clinician. It’s a great example of how technology can be leveraged to enhance care.”
 

Working behind the scenes

Together with gastroenterologist Deborah Anne Fisher, MD, an associate professor of medicine at Duke, Dr. Grego and colleagues devised a prototype that positions the image analyzer in the pipes behind the toilet. So the analysis is done post flush.

“We are experts of toilets and toilet technology,” Dr. Grego said. “We have learned that people really don’t like to see anything weird around the toilet bowl.”

The smart toilet system is designed for multiple users in a residential or commercial setting. The technology could be used in hospitals or long-term care facilities, for example. A fingerprint scanner on the flush mechanism tracks each individual user.
 

Mixed reactions

Dr. Grego gets a range of reactions when she tells people she is developing smart toilet technology.

“Friends and family laugh about the concept of the smart toilet,” she said, “so all the possible jokes that have been done on poops, we know.”

In fact, the researchers also are collecting the jokes they hear. “We’re being very systematic.”

In contrast, gastroenterologists who learn of the technology in development are more enthusiastic, Dr. Grego said. “There is such a need for removing the uncertainty of the patient recall about bowel movement frequency and appearance.

“We are seeking to expand through collaboration with additional GI doctors. We want to develop a more advanced prototype and do further validation studies,” Dr. Grego said.
 

Digital health tool

There is an aversion among patients to handling stool “or even talking about it,” Dr. Grego said. Colleagues tell her that people are more willing to provide a blood sample, which requires a needle, than a stool sample.

“But a lot of health data is there [in the stool],” she added. “We think this will empower a lot of research as well as consumer data gathering.”

For example, Dr. Grego envisions pharmaceutical companies using the technology to detect or monitor any changes in stool or gut health based on a treatment in development during clinical trials.

Furthermore, the technology might empower health-conscious consumers who want to track their own gut health. “This technology will be a whole new entry in the digital health toolkit,” Dr. Grego said.

Although not included in the research presented at this year’s DDW, the developers plan to add a sampling capability. Biochemic analysis of stool samples could provide “metabolically relevant information,” including stool biomarkers and microbiome composition.

“We have demonstrated it in the laboratory. It will be part of the technology when developed into a product,” Dr. Grego said.

This proof-of-concept study “is the first step in a path we are aggressively pursuing,” Dr. Grego said. She estimated it will take about 12-18 months to develop a prototype for use with patients. “We hope to move to a product soon after that.”

“I’m looking forward to seeing future iterations of this tool,” Dr. Shin said. “It could have a role in monitoring important GI diseases and disorders, including IBS and inflammatory bowel disease, or even for the detection of ‘alarm symptoms’ that shouldn’t be ignored.

“I could even see it having a role in preventative health in the future,” Dr. Shin added. 

The technology has been licensed to the spin-off company Coprata to develop the product further.

“We hope to have an impact on people’s health very soon,” Dr. Grego said.  

Duke University funded the study. Dr. Grego holds a management position at Coprata. Dr. Shin disclosed no relevant financial relationships.
