COVID can mimic prostate cancer symptoms
This patient has a strong likelihood of aggressive prostate cancer, right? If that same patient also presents with severe, burning bone pain with no precipitating trauma to the area and rest and over-the-counter painkillers are not helping, you’d think, “check for metastases,” right?
That patient was me in late January 2023.
As a research scientist member of the American Urological Association, I knew enough to know I had to consult my urologist ASAP.
With the above symptoms, I’ll admit I was scared. Fortunately, if that’s the right word, I was no stranger to a rapid, dramatic spike in PSA. In 2021 I was temporarily living in a new city, and I wanted to form a relationship with a good local urologist. The urologist that I was referred to gave me a thorough consultation, including a vigorous digital rectal exam (DRE) and sent me across the street for a blood draw.
To my shock, my PSA had spiked over 2 points, to 9.9 from 7.8 a few months earlier. I freaked. Had my 3-cm tumor burst out into an aggressive cancer? Research on PubMed provided an array of studies showing what could cause PSA to suddenly rise, including a DRE performed 72 hours before the blood draw.1 A week later, my PSA was back down to its normal 7.6.
But in January 2023, I had none of those previously reported experiences that could suddenly trigger a spike in PSA, like a DRE or riding on a thin bicycle seat for a few hours before the lab visit.
The COVID effect
I went back to PubMed and found a new circumstance that could cause a surge in PSA: COVID-19. A recent study2 of 91 men with benign prostatic hypertrophy by researchers in Turkey found that PSA spiked from 0 to 5 points during the COVID infection period and up to 2 points higher 3 months after the infection had cleared. I had tested positive for COVID-19 in mid-December 2022, 4 weeks before my 9.9 PSA reading.
Using Google translate, I communicated with the team in Turkey and found out that the PSA spike can last up to 6 months.
That study helps explain why my PSA dropped over 1.5 points to 8.5 just 2 weeks after the 9.9 reading, with the expectation that it would return to its previous normal of 7.8 within 6 months of infection with SARS-CoV-2. To be safe, my urologist scheduled another PSA test in May, along with an updated multiparametric MRI, which may be followed by an in-bore MRI-guided biopsy of the 3-cm tumor if the mass has enlarged.
COVID-19 pain
What about my burning bone pain in my upper right humerus and right rotator cuff that was not precipitated by trauma or strain? A radiograph found no evidence of metastasis, thank goodness. And my research showed that several studies3 have found that COVID-19 can cause burning musculoskeletal pain, including enthesopathy, which is what I had per the radiology report. So my PSA spike and searing pain were likely consequences of the infection.
To avoid the risk for a gross misdiagnosis after a radical spike in PSA, the informed urologist should ask the patient if he has had COVID-19 in the previous 6 months. Overlooking that question could lead to the wrong diagnostic decisions about a rapid jump in PSA or unexplained bone pain.

Depression tied to inflammation and survival in lung cancer
suggests a new study.
The findings underscore the importance of assessing and treating depression in patients with cancer, particularly given the high rate of depression among those with lung cancer versus other types of cancer, the investigators said.
The study involved 186 patients with newly diagnosed stage IV non–small cell lung cancer (NSCLC), of whom 35% had self-reported moderate to severe depressive symptoms.
Depression was reliably associated with lung-relevant systemic inflammation responses (SIRs), which included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and Advanced Lung Cancer Inflammation Index (ALI) score.
These SIRs were prognostic for 2-year OS.
Overall mortality at 2 years was 61%. Higher NLRs and PLRs and lower ALI scores all predicted worse OS (hazard ratio, 1.91, 2.08, and 0.53, respectively).
The findings were published online in PLoS ONE (2023 Feb 24.
“These patients with high levels of depression are at much higher risk for poor outcomes,” but the key finding was that patients with the highest depression levels were driving the relationship, lead author Barbara Andersen, PhD, professor of psychology at Ohio State University, Columbus, stated in a press release.
“It was patients with high depression levels who had strikingly higher inflammation levels, and that is what really drove the correlation we saw,” she explained.
For example, 56% of patients with no depression symptoms or only mild depression symptoms had a PLR above the cutoff for dangerous levels of inflammation, compared with 42% whose PLR was below the cutoff. However, among those with high depression levels, 77% and 23% had a PLR above and below the cutoff, respectively.
“These highly depressed patients were 1.3-3 times more likely to have high inflammation levels, even after controlling for other factors related to inflammation biomarker levels, including demographics and smoking status,” Dr. Andersen noted.
“Depression levels may be as important or even more important than other factors that have been associated with how people fare with lung cancer,” she suggested.
In a previous study, the team controlled for baseline depression and found that “the trajectory of depression from diagnosis through 2 years (18 assessments) predicted NSCLC patients’ survival (HR, 1.09), above and beyond baseline depression, sociodemographics, smoking status, cell type, and receipt of targeted treatments and immunotherapies.”
“Taken together, data support psychological, behavioral, and biologic toxicities of depression capable of influencing treatment response and/or survival,” they wrote.
“The results may help explain why a substantial portion of lung cancer patients fail to respond to new immunotherapy and targeted treatments that have led to significantly longer survival for many people with the disease,” Dr. Andersen said.
The investigators concluded that “intensive study of depression among patients with NSCLC, combined with measures of cell biology, inflammation, and immunity, is needed to extend these findings and discover their mechanisms, with the long-term aim to improve patients’ quality of life, treatment responses, and longevity.”
This study was funded by the Ohio State University Comprehensive Cancer Center and Pelotonia through grants to individual authors. Dr. Andersen reported having no relevant disclosures.

What’s the ‘secret sauce’ to help patients move more?
“Just Do It” is a cute marketing slogan. But let’s face it: Clinically, it doesn’t work well. Most people just don’t exercise. according to recent data from the Centers for Disease Control and Prevention.
Furthermore, when surveyed about aerobic exercise and strength training, only 24.6% meet these weekly recommendations. These low rates of physical activity are alarming, given the immense benefits of exercise in improving mental and physical health and well-being.
Many people know that exercise is good for them but struggle to go workout consistently. I know firsthand how challenging this can be. In addition to being an integrative obesity specialist, I have gone from 0 minutes of physical activity in 2014 to becoming a fitness enthusiast who’s run more than 5,300 miles over 8 years. I know that as doctors and clinicians, we can profoundly influence our patients’ exercise journey.
Here are five tips to help motivate your patients make the change from “I Won’t Do It” to “I’m Doing It.”
Tip 1: ‘[Clinician], heal thyself’
Data don’t lie. Doctors who move more are more likely to counsel patients on exercise. I’ve been the doctor on both sides of the exercise spectrum. At my heaviest weight and lowest physical activity level, I felt hypocritical counseling patients on exercise.
If and when I counseled my patients on exercise, it was very directive and impersonal. When I started running consistently, I went to the opposite end of the spectrum. In my running zeal, it took a while for me to understand that not everyone wants to run dozens of miles a week. Shocking! Some people can’t handle intense workouts. The “I did it so you can too” perspective wasn’t helpful for long-term change in most patients.
What has been beneficial is recalling the obstacles and emotions I had (and still have) with staying consistent with physical activity. When physicians and clinicians move regularly, we’re more equipped to give our patients genuine counseling based on practicality rather than theory.
Now that self-reflection has been addressed, let’s get to patient counseling.
Tip 2: Motivate, don’t berate
Lectures on why patients should exercise are less helpful than asking, “Why aren›t you able to exercise more often?”
Asking open-ended questions is essential in motivational interviewing. Motivational interviewing promotes behavioral change through collaborative conversation.
Instead of telling the patient what to do, motivational interviewing seeks to establish a person’s why and create an effective plan based on their motivation. Asking open-ended questions is also helpful in determining any challenges to regular exercise, rather than calling these challenges “excuses,” which can be counterproductive.
I encourage patients to embrace challenges as opportunities for improvement. If they say: “I can’t find time to work out,” I suggest that they create time to work out by walking 10-15 minutes during lunch or after dinner. The information gleaned from open-ended questions helps set practical SMARTER goals, which we will discuss next.
Tip 3: Set SMARTER goals
After assessing the patient’s motivation and barriers, use this information to transform their desire to change into an actionable plan through a SMARTER goal. SMARTER stands for Specific, Measurable, Attainable, Relevant, Time-Sensitive, Enjoyable, and Rewarding. Practical goals have each of these components. That’s why “Just Do It” or even “Exercise 150 minutes a week” isn’t a clear path for actionable change. SMARTER goals go beyond what to do and help people personalize how to change.
For example, the SMARTER version of “exercise 150 minutes a week” for a busy person who works 50 hours a week may look like this: “My goal is to incorporate 150 minutes of physical activity through 60 minutes of aerobic exercise Monday through Friday (20-minute lunch walks) and 90 minutes of combination resistance training on the weekend (two 45-minute sessions) while listening to my favorite music. To meet my goal, I will reward myself by calling a friend to catch up or buy myself a new workout outfit.”
Exercise prescriptions are another helpful way to empower patients with a realistic exercise strategy. In my practice, I developed my own exercise prescription which focuses on overcoming time barriers to exercise and finding personally enjoyable exercises. To enhance self-directed physical activity, I›ve found it useful to have patients complete part of the “exercise prescription” on their own before or after their visit.
Tip 4: Use accountability tools
Making a SMARTER goal is one thing, but sticking with it takes regular reinforcement. Even with the best plan, once patients leave the office, there are many distractions from their goals. Accountability is the secret sauce to cultivating consistency. Fitness trackers are an affordable form of accountability. Studies show that wearing a fitness tracker can help people get up to 40 minutes of extra walking, compared with people who don’t wear trackers.
Additionally, clinicians can use different ways to offer exercise accountability. For example, more frequent check-ins, individually or in groups, can be helpful. The increase in telehealth has made interval visits easier. Reimbursement and time can limit clinician-level accountability, however. Other options are referring patients to online support groups or programs sponsored by the government or organizations. For years, I coled a Walk With a Doc chapter in Richmond, Va. There are chapters throughout the country.
Tip 5: Prepare and PLAN for setbacks
Breaking news: Most plans don’t go quite as envisioned. Accounting for the potential of setbacks early on helps patients set realistic expectations. As physicians and clinicians, we can help our patients anticipate a few likely obstacles. This may lessen the impact when a setback occurs. Also, it’s helpful to have the patient prepare for a setback with a PLAN for recovering quickly. PLAN stands for Ponder what happened; Learn from it; Adjust the original goal; Now get back on track. Getting back on track as soon as possible is important to keep patients motivated and prevent muscle deconditioning.
Exercise is medicine. Physical inactivity is a leading contributor to many preventable diseases. Although the physical activity statistics are disappointing, improvement is possible. Many systemic changes are needed to increase physical activity on a population level.
While waiting for more extensive changes, we have the power to equip patients with personalized, actionable tools for improving and maintaining physical activity.
We can transform one person at a time through our clinical encounters. Let’s use effective tools to help patients shift from “I Won’t Do It” to “I’m Doing It.”

“Just Do It” is a cute marketing slogan. But let’s face it: Clinically, it doesn’t work well. Most people just don’t exercise. according to recent data from the Centers for Disease Control and Prevention.
Furthermore, when surveyed about aerobic exercise and strength training, only 24.6% meet these weekly recommendations. These low rates of physical activity are alarming, given the immense benefits of exercise in improving mental and physical health and well-being.
Many people know that exercise is good for them but struggle to go workout consistently. I know firsthand how challenging this can be. In addition to being an integrative obesity specialist, I have gone from 0 minutes of physical activity in 2014 to becoming a fitness enthusiast who’s run more than 5,300 miles over 8 years. I know that as doctors and clinicians, we can profoundly influence our patients’ exercise journey.
Here are five tips to help motivate your patients make the change from “I Won’t Do It” to “I’m Doing It.”
Tip 1: ‘[Clinician], heal thyself’
Data don’t lie. Doctors who move more are more likely to counsel patients on exercise. I’ve been the doctor on both sides of the exercise spectrum. At my heaviest weight and lowest physical activity level, I felt hypocritical counseling patients on exercise.
If and when I counseled my patients on exercise, it was very directive and impersonal. When I started running consistently, I went to the opposite end of the spectrum. In my running zeal, it took a while for me to understand that not everyone wants to run dozens of miles a week. Shocking! Some people can’t handle intense workouts. The “I did it so you can too” perspective wasn’t helpful for long-term change in most patients.
What has been beneficial is recalling the obstacles and emotions I had (and still have) with staying consistent with physical activity. When physicians and clinicians move regularly, we’re more equipped to give our patients genuine counseling based on practicality rather than theory.
Now that self-reflection has been addressed, let’s get to patient counseling.
Tip 2: Motivate, don’t berate
Lectures on why patients should exercise are less helpful than asking, “Why aren›t you able to exercise more often?”
Asking open-ended questions is essential in motivational interviewing. Motivational interviewing promotes behavioral change through collaborative conversation.
Instead of telling the patient what to do, motivational interviewing seeks to establish a person’s why and create an effective plan based on their motivation. Asking open-ended questions is also helpful in determining any challenges to regular exercise, rather than calling these challenges “excuses,” which can be counterproductive.
I encourage patients to embrace challenges as opportunities for improvement. If they say: “I can’t find time to work out,” I suggest that they create time to work out by walking 10-15 minutes during lunch or after dinner. The information gleaned from open-ended questions helps set practical SMARTER goals, which we will discuss next.
Tip 3: Set SMARTER goals
After assessing the patient’s motivation and barriers, use this information to transform their desire to change into an actionable plan through a SMARTER goal. SMARTER stands for Specific, Measurable, Attainable, Relevant, Time-Sensitive, Enjoyable, and Rewarding. Practical goals have each of these components. That’s why “Just Do It” or even “Exercise 150 minutes a week” isn’t a clear path for actionable change. SMARTER goals go beyond what to do and help people personalize how to change.
For example, the SMARTER version of “exercise 150 minutes a week” for a busy person who works 50 hours a week may look like this: “My goal is to incorporate 150 minutes of physical activity through 60 minutes of aerobic exercise Monday through Friday (20-minute lunch walks) and 90 minutes of combination resistance training on the weekend (two 45-minute sessions) while listening to my favorite music. To meet my goal, I will reward myself by calling a friend to catch up or buy myself a new workout outfit.”
Exercise prescriptions are another helpful way to empower patients with a realistic exercise strategy. In my practice, I developed my own exercise prescription which focuses on overcoming time barriers to exercise and finding personally enjoyable exercises. To enhance self-directed physical activity, I›ve found it useful to have patients complete part of the “exercise prescription” on their own before or after their visit.
Tip 4: Use accountability tools
Making a SMARTER goal is one thing, but sticking with it takes regular reinforcement. Even with the best plan, once patients leave the office, there are many distractions from their goals. Accountability is the secret sauce to cultivating consistency. Fitness trackers are an affordable form of accountability. Studies show that wearing a fitness tracker can help people get up to 40 minutes of extra walking, compared with people who don’t wear trackers.
Additionally, clinicians can use different ways to offer exercise accountability. For example, more frequent check-ins, individually or in groups, can be helpful. The increase in telehealth has made interval visits easier. Reimbursement and time can limit clinician-level accountability, however. Other options are referring patients to online support groups or programs sponsored by the government or organizations. For years, I coled a Walk With a Doc chapter in Richmond, Va. There are chapters throughout the country.
Tip 5: Prepare and PLAN for setbacks
Breaking news: Most plans don’t go quite as envisioned. Accounting for the potential of setbacks early on helps patients set realistic expectations. As physicians and clinicians, we can help our patients anticipate a few likely obstacles. This may lessen the impact when a setback occurs. Also, it’s helpful to have the patient prepare for a setback with a PLAN for recovering quickly. PLAN stands for Ponder what happened; Learn from it; Adjust the original goal; Now get back on track. Getting back on track as soon as possible is important to keep patients motivated and prevent muscle deconditioning.
Exercise is medicine. Physical inactivity is a leading contributor to many preventable diseases. Although the physical activity statistics are disappointing, improvement is possible. Many systemic changes are needed to increase physical activity on a population level.
While waiting for more extensive changes, we have the power to equip patients with personalized, actionable tools for improving and maintaining physical activity.
We can transform one person at a time through our clinical encounters. Let’s use effective tools to help patients shift from “I Won’t Do It” to “I’m Doing It.”

Liquid albuterol shortage effects reduced by alternative drugs, similar shortages may be increasingly common
The shortage of 0.5% albuterol sulfate inhalation solution, first reported by the FDA last October, gained increasing attention earlier this month when Akorn Pharmaceuticals – one of just two companies making the product – shut down after years of financial and regulatory troubles.
The other manufacturer, Nephron Pharmaceuticals, is producing 0.5% albuterol “as fast as possible” to overcome the shortage, CEO Lou Kennedy said in a written comment.
Meanwhile, the more commonly used version of liquid albuterol, with a concentration of 0.083%, remains in “good supply from several manufacturers,” according to an FDA spokesperson.
Still, headlines concerning the shortage have caused “a bit of a panic” for patients with asthma and parents with asthmatic children, according to David R. Stukus, MD, professor of clinical pediatrics in the division of allergy and immunology at Nationwide Children’s, Columbus, Ohio.
Much of the media coverage has lacked context, causing unnecessary worry, he said, as the shortage only affects one type of albuterol generally reserved for inpatient and emergency use.
“The shortage has not impacted our albuterol inhalers thus far,” Dr. Stukus said in an interview. “So I certainly don’t want people with asthma to panic that they’re going to run out of their inhaler anytime soon.”
Even infants and toddlers can use inhalers
Although Dr. Stukus noted that certain patients do require nebulizers, such as those with conditions that physically limit their breathing, like muscular dystrophy, most patients can use inhalers just fine. He said it’s a “pretty common misconception, even among medical professionals,” that infants and toddlers need nebulizers instead.
“In our institution, for example, we rarely ever start babies on a nebulizer when we diagnose them with asthma,” Dr. Stukus said. “We often just start right away with an inhaler with a spacer and a face mask.”
The shortage of liquid albuterol may therefore have a silver lining, he suggested, as it prompts clinicians to reconsider their routine practice.
“When situations like this arise, it’s a great opportunity for all of us to just take a step back and reevaluate the way we do things,” Dr. Stukus said. “Sometimes we just get caught up with inertia and we continue to do things the same way even though new options are available, or evidence has changed to the contrary.”
Nathan Rabinovitch, MD, professor of pediatrics in the division of pediatric allergy and clinical immunology at National Jewish Health, Denver, said that his center had trouble obtaining liquid albuterol about 2 weeks ago, so they pivoted to the more expensive levalbuterol for about a week and a half, until their albuterol supply was restored.
While Dr. Rabinovitch agreed that most children don’t need a nebulizer, he said about 5%-10% of kids with severe asthma should have one on hand in case their inhaler fails to control an exacerbation.
Personal preferences may also considered, he added.
“If [a parent] says, ‘I like to use the nebulizer. The kid likes it,’ I’m fine if they just use a nebulizer.”
One possible downside of relying on a nebulizer, however, is portability, according to Kelly O’Shea, MD, assistant professor in the division of allergy and clinical immunology at the University of Michigan, Ann Arbor.
“If you’re out at the park or out at a soccer game with your kids, and they are having trouble breathing ... and they need their albuterol, you don’t have that ability if you are tied to a nebulizer,” Dr. O’Shea said in an interview. “As long as a parent feels comfortable – they feel like [their child] can get deep breaths in, I agree that you can use [an inhaler] in the infant and toddler population.”
She also agreed that a nebulizer may serve as a kind of second step if an inhaler isn’t controlling an exacerbation; however, she emphasized that a nebulizer should not be considered a replacement for professional care, and should not give a false sense of security.
“I caution parents to make sure that when they need it, they also take the next step and head over to the emergency room,” Dr. O’Shea said.
Generic drug shortages becoming more common
While the present scarcity of liquid albuterol appears relatively mild in terms of clinical impact, it brings up broader concerns about generic drug supply, and why shortages like this are becoming more common, according to Katie J. Suda, PharmD, MS, professor of medicine and pharmacy, and associate director, center for pharmaceutical policy and prescribing at the University of Pittsburgh.
“Drug shortages continue to increase in frequency, and the duration and severity of the shortages are also getting worse,” Dr. Suda said in an interview.
The reasons for these shortages can be elusive, according to 2022 report by the American Society of Health-System Pharmacists, which found that more than half of shortages came with no explanation from manufacturers.
The same report showed that only 5% of shortages were due to a “business decision,” but this factor is likely more central than publicly stated.
A recent FDA analysis on drug shortages, for instance, lists “lack of incentives to produce less profitable drugs,” as the first “root cause,” and Dr. Suda agrees.
“It’s important that we have generic medicines to decrease costs to our health systems, as well as for our patients,” Dr. Suda said. “But frequently, with those generic products, the price is driven so low that it increases the risk of a shortage.”
The drive to maintain profit margins may motivate companies to cut corners in production, Dr. Suda explained. She emphasized that this connection is speculative, because motivations are effectively unknowable, but the rationale is supported by past and present shortages.
Akorn Pharmaceuticals, for example, received a warning letter from the FDA in 2019 because of a variety of manufacturing issues, including defective bottles, questionable data, and metal shavings on aseptic filling equipment.
When a manufacturer like Akorn fails, the effects can be far-reaching, Dr. Suda said, noting their broad catalog of agents. Beyond liquid albuterol, Akorn was producing cardiac drugs, antibiotics, vitamins, local anesthetics, eye products, and others.
Drug shortages cause “a significant strain on our health care system,” Dr. Suda said, and substituting other medications increases risk of medical errors.
Fortunately, the increasing number of drug shortages is not going unnoticed, according to Dr. Suda. The FDA and multiple other organizations, including the ASHP, American Medical Association, and National Academies of Sciences, Engineering, and Medicine, are all taking steps to ensure that essential medicines are in steady supply, including moves to gather more data from manufacturers.
“I hope that a lot of the efforts that are moving forward ... will help us decrease the impact of shortages on our patients,” Dr. Suda said.

Brain imaging markers of breathlessness-expectation predict COPD rehabilitation success
In an experimental medicine study of D-cycloserine given during chronic obstructive pulmonary disease (COPD) rehabilitation, only models including brain imaging markers of breathlessness-expectation successfully predicted Dyspnea-12 score improvement. D-cycloserine was independently associated with breathlessness improvement, according to original research published in Thorax.
Chronic breathlessness persisting despite maximal medical therapy is a key feature of COPD. While pulmonary rehabilitation is the best treatment for chronic breathlessness in COPD, responses to treatment are variable, with 30% deriving no clinical benefit, Sarah L. Finnegan, PhD, with the Nuffield Department of Clinical Neurosciences, University of Oxford (England), and colleagues wrote.
While recent research has shown fear and anxiety to be key components of the expectation that plays an important role in the mechanisms and maintenance of breathlessness, expectation-related effects have not previously been considered in prediction studies of pulmonary rehabilitation outcomes. The authors’ prior research showed a clear correlation between improvements in breathlessness through pulmonary rehabilitation and expectation-related brain activity in areas that include the anterior insula, anterior cingulate cortex, and prefrontal cortex. That research methodology, however, did not attempt to predict individual responses.
The current study focused on brain activity changes within preselected regions associated with breathlessness-expectation and body and symptom perception. Its purpose was to predict improvements in breathlessness during pulmonary rehabilitation by analyzing baseline data from a longitudinal experimental medicine study of D-cycloserine on breathlessness during pulmonary rehabilitation. D-cycloserine, a partial agonist of brain N-methyl-D-aspartate receptors, was chosen because of its effects on neural plasticity and influence on brain expectation mechanisms associated with cognitive behavioral therapies. The authors hypothesized that baseline brain activity in response to breathlessness-related expectation would predict improvement in breathlessness through pulmonary rehabilitation, with D-cycloserine emerging as a significant factor in the prediction model.
The researchers recruited 71 participants (18 women, median age 71 years [46-85 years]) with mild to moderate COPD immediately prior to enrollment in a National Health Service–prescribed course of pulmonary rehabilitation. They were randomized double-blind to receive either 250 mg oral D-cycloserine or a matched placebo. Participants received a single dose on four occasions 30 minutes prior to the onset of the first four pulmonary rehabilitation sessions.
Baseline variables, including brain-activity, self-report questionnaires responses, clinical measures of respiratory function, and drug allocation were used to train three machine-learning models to predict the outcome, a minimally clinically relevant change in the Dyspnea-12 score.
Improvements in Dyspnea-12 score occurred only in the two models including brain imaging markers of breathlessness-expectation (sensitivity 0.88, specificity 0.77). The model that combined brain and behavior metrics produced the best classification performance (accuracy, 0.83 [95% confidence interval, 0.75-0.90]; sensitivity, 0.88; specificity, 0.77; P < 0.001). While the brain-only model was able to correctly categorize participants with statistically significant likelihood (accuracy, 0.70 [95% CI, 0.58-0.81]), it demonstrated poor goodness of fit, a measure of how well sample data fit a distribution from a population with a normal distribution. “By enriching the brain-only models with questionnaires and physiology measures improved performance considerably,” the researchers stated.
“Our findings demonstrate the first predictive model of change in breathlessness across pulmonary rehabilitation and, for the first time, the clinical relevance of expectation-related brain activity as a therapeutic target in the treatment of breathlessness. ... This was achieved using sensitive brain imaging techniques in order to capture personalized responses to breathlessness-expectation which has, until recently remained relatively unexplored.”
“This study raises interesting questions about breathlessness-expectations,” commented assistant professor of medicine Mary Jo S. Farmer, MD, PhD, director pulmonary hypertension service, University of Massachusetts, Worcester, in an interview. “There is much more to be understood about expectations pathways as to how these pathways are built upon prior experience and pave the way for reaction to future experiences. There is need for a similar study with larger sample size and clarification of the role of the effect of the agent D-cycloserine on breathlessness-expectation.”
The researchers noted their study’s limitations, pointing out that the small sample size precluded holding out a proportion of the original data to create an external validation dataset.
Dr. Finnegan and Dr. Farmer declared no disclosures relevant to this study. This work was supported by the JABBS Foundation and Dunhill Medical Trust. This research was funded in whole, or in part, by the Wellcome Trust.

While the brain-only model was able to correctly categorize participants with statistically significant likelihood (accuracy, 0.70 [95% CI, 0.58-0.81]), it demonstrated poor goodness of fit, a measure of how well sample data fit a distribution from a population with a normal distribution. “By enriching the brain-only models with questionnaires and physiology measures improved performance considerably,” the researchers stated.
“Our findings demonstrate the first predictive model of change in breathlessness across pulmonary rehabilitation and, for the first time, the clinical relevance of expectation-related brain activity as a therapeutic target in the treatment of breathlessness. ...

“This study raises interesting questions about breathlessness-expectations,” commented assistant professor of medicine Mary Jo S. Farmer, MD, PhD, director pulmonary hypertension service, University of Massachusetts, Worcester, in an interview. “There is much more to be understood about expectations pathways as to how these pathways are built upon prior experience and pave the way for reaction to future experiences. There is need for a similar study with larger sample size and clarification of the role of the effect of the agent D-cycloserine on breathlessness-expectation.”
The researchers noted their study’s limitations, pointing out that the small sample size precluded holding out a proportion of the original data to create an external validation dataset.

In an experimental medicine study of D-cycloserine given during chronic obstructive pulmonary disease (COPD) rehabilitation, only models including brain imaging markers of breathlessness-expectation successfully predicted Dyspnea-12 score improvement. D-cycloserine was independently associated with breathlessness improvement, according to original research published in Thorax.
Chronic breathlessness persisting despite maximal medical therapy is a key feature of COPD. While pulmonary rehabilitation is the best treatment for chronic breathlessness in COPD, responses to treatment are variable, with 30% deriving no clinical benefit, Sarah L. Finnegan, PhD, with the Nuffield Department of Clinical Neurosciences, University of Oxford (England), and colleagues wrote.
While recent research has shown fear and anxiety to be key components of the expectation that plays an important role in the mechanisms and maintenance of breathlessness, expectation-related effects have not previously been considered in prediction studies of pulmonary rehabilitation outcomes. The authors’ prior research showed a clear correlation between improvements in breathlessness through pulmonary rehabilitation and expectation-related brain activity in areas that include the anterior insula, anterior cingulate cortex, and prefrontal cortex. That research methodology, however, did not attempt to predict individual responses.
The current study focused on brain activity changes within preselected regions associated with breathlessness-expectation and body and symptom perception. Its purpose was to predict improvements in breathlessness during pulmonary rehabilitation by analyzing baseline data from a longitudinal experimental medicine study of D-cycloserine on breathlessness during pulmonary rehabilitation. D-cycloserine, a partial agonist of brain N-methyl-D-aspartate receptors, was chosen because of its effects on neural plasticity and influence on brain expectation mechanisms associated with cognitive behavioral therapies. The authors hypothesized that baseline brain activity in response to breathlessness-related expectation would predict improvement in breathlessness through pulmonary rehabilitation, with D-cycloserine emerging as a significant factor in the prediction model.
The researchers recruited 71 participants (18 women, median age 71 years [46-85 years]) with mild to moderate COPD immediately prior to enrollment in a National Health Service–prescribed course of pulmonary rehabilitation. They were randomized double-blind to receive either 250 mg oral D-cycloserine or a matched placebo. Participants received a single dose on four occasions 30 minutes prior to the onset of the first four pulmonary rehabilitation sessions.
Baseline variables, including brain-activity, self-report questionnaires responses, clinical measures of respiratory function, and drug allocation were used to train three machine-learning models to predict the outcome, a minimally clinically relevant change in the Dyspnea-12 score.
Improvements in Dyspnea-12 score occurred only in the two models including brain imaging markers of breathlessness-expectation (sensitivity 0.88, specificity 0.77). The model that combined brain and behavior metrics produced the best classification performance (accuracy, 0.83 [95% confidence interval, 0.75-0.90]; sensitivity, 0.88; specificity, 0.77; P < 0.001).

FROM THORAX
NOVIDs: Do some have the genes to dodge COVID?
As a field service representative for a slot machine company, Ryan Alexander, 37, of Louisville, Ky., spends his working hours in casinos, covering a large territory including Norfolk, Va., Indianapolis, and Charlotte. Social distancing in the casinos is not the norm. Despite all this up-close contact with people, he said he is still COVID-free, 3 years into the pandemic.
There was one nervous night when his temperature rose to 101° F, and he figured the virus had caught up with him. “I took a test and was fine,” he said, relieved that the result was negative. The fever disappeared, and he was back to normal soon. “Maybe it was just an exhausting day.”
Mr. Alexander is one of those people who have managed – or at least think they have managed – to avoid getting COVID-19.
He is, some say, a NOVID. While some scientists cringe at the term, it’s caught on to describe these virus super-dodgers. Online entrepreneurs offer NOVID-19 T-shirts, masks, and stickers, in case these super-healthy or super-lucky folks want to publicize their good luck. On Twitter, NOVIDs share stories of how they’ve done it.
How many NOVIDs?
As of March 16, according to the CDC, almost 104 million cases of COVID – about one-third of the U.S. population – have been reported, but many cases are known to go unreported. About half of American adults surveyed said they have had COVID, according to a December report by the COVID States Project, a multiuniversity effort to supply pandemic data.
As the numbers settle over time, though, it becomes clearer that some in the U.S. have apparently managed to avoid the virus.
But some scientists bristle at the term NOVIDs. They prefer the term “resisters,” according to Elena Hsieh, MD, associate professor of pediatrics and immunology at the University of Colorado at Denver, Aurora. Currently, she said, there is much more information on who is more susceptible to contracting severe COVID than who is resistant.
Dr. Hsieh is one of the regional coordinators for the COVID Human Genetic Effort, an international consortium of more than 250 researchers and doctors dedicated to discovering the genetic and immunological bases of the forms of SARS-CoV-2 infection. These researchers and others are looking for explanations for why some people get severe COVID while others seem resistant despite repeated exposure.
Resistance research
In determining explanations for resistance to infection, “the needle in the haystack that we are looking for is a change in the genetic code that would allow for you to avoid entry of the virus into the cell,” Dr. Hsieh said. “That is what being resistant to infection is.”
Part of the reason it’s so difficult to study resistance is defining a resister, she said. While many people consider themselves among that group because they’re been exposed multiple times – even with close family members infected and sick, yet they still felt fine – that doesn’t necessarily make them a resister, she said.
Those people could have been infected but remained without symptoms. “Resistance means the virus was inside you, it was near your cell and it did not infect your cell,” Dr. Hsieh said.
“I don’t think we know a lot so far,” Dr. Hsieh said about resisters. “I do believe that, just like there are genetic defects that make someone more susceptible, there are likely to be genetic defects that make somebody less susceptible.’’
“To identify genetic variants that are protective is a really challenging thing to do,” agreed Peter K. Gregersen, MD, professor of genetics at the Feinstein Institutes for Medical Research at Northwell Health in Manhasset, N.Y. Dr. Gregersen is also a regional coordinator for the COVID Human Genetic Effort.
He suspects the number found to be truly resistant to COVID – versus dodging it so far – is going to be very small or not found at all.
“It may exist for COVID or it may not,” he said. Some people may simply have what he calls a robust immune response in the upper part of the throat, perhaps killing off the virus quickly as soon as it enters, so they don’t get a positive test.
Genetic resistance has been found for other diseases, such as HIV.
“For HIV, scientists have been able to identify a specific gene that codes for a protein that can prevent individuals from getting infected,” said Sabrina Assoumou, MD, MPH, professor of medicine at Boston University, who researches HIV.
However, she said, “we haven’t yet found a similar gene or protein that can prevent people from getting infected with SARS-CoV-2.”
What has been found “is that some people might have a mutation in a gene that encodes for what’s called human leukocyte antigen (HLA),” Dr. Assoumou said. HLA, a molecule found on the surface of most cells, has a crucial role in the immune response to foreign substances. “A mutation in HLA can make people less likely to have symptoms if they get infected. Individuals still get infected, but they are less likely to have symptoms.”
Other research has found that those with food allergies are also less likely to be infected. The researchers have speculated that the inflammation characteristic of allergic conditions may reduce levels of a protein called the ACE2 receptor on the surface of airway cells. The SARS-CoV-2 virus uses the receptor to enter the cells, so if levels are low, that could reduce the ability of the virus to infect people.
The COVID Human Genetic Effort continues to search for participants, both those who were admitted to a hospital or repeatedly seen at a hospital because of COVID, as well as those who did not get infected, even after “intense and repeated” exposure.
The number of people likely to be resistant is much smaller, Dr. Hsieh said, than the number of people susceptible to severe disease.
The testing ... or lack thereof factor
The timing of testing and a person’s “infection profile” may be factors in people incorrectly declaring themselves NOVIDs, said Anne Wyllie, PhD, a research scientist in epidemiology at the Yale School of Public Health in New Haven, Conn., and a codeveloper of a saliva PCR test for COVID.
“Infection profiles can vary between individuals,” she said. For some, the infection may start in the lower respiratory tract, others in the higher respiratory tract. “Depending on where the virus takes up residence, that can affect test results.”
Then there’s the following-instructions factor. “It’s very likely that due to tests not being done at the right time, with the right sample, or not repeated if there is ongoing evidence of symptoms, that there are individuals out there who believe they are NOVIDs but just missed catching their infection at the window of opportunity.” Dr. Wyllie said.
Susceptibility research
“The part we have proven is the genetic defect that would make you more susceptible to having severe disease,” Dr. Hsieh said.
Many published papers report that inherited and/or autoimmune deficiencies of type I interferon immunity, important for combating viral infections and modulating the immune response, can be a significant cause of life-threatening COVID pneumonia.
More recently, researchers, including Jean-Laurent Casanova, MD, PhD, professor at Rockefeller University, New York, and cofounder of the COVID Human Genome Effort, reported that deficiencies in a gene that plays a role in built-in immunity (the early response), and a gene involved in signaling within the immune cells, impair interferon production and may be the basis of severe COVID pneumonia.
NOVIDs’ habits run the gamut
As scientists continue their research, the NOVIDs have their own ideas about why they’ve dodged the pandemic bullet, and they have a variety of approaches to handling the pandemic now.
Ryan Alexander, the field rep who travels to casinos, is up to date on his vaccinations and has gotten all the recommended COVID shots. “I was wearing a mask when told to wear masks,” he said.
He still observes the social distance habit but lives life. “I’ve been to three or four concerts in the past couple of years.”
And does he worry his number will eventually be up? “Not at this point, no,” he said.
Joe Asher, 46, said he has not gotten COVID despite being in contact with about 100 people a day, on average. He works as a bartender at an Evansville, Ind., brewery.
“On a Friday night, we can get 500 people,” he said. “I feel like almost everyone at the brewery got it. There’s no way I wasn’t exposed to it all the time.”
However, he said, his coworkers who did get sick were very cautious about not infecting others, partly to help protect a coworker’s family with newborn twins, so that may have helped him stay uninfected, too.
Mr. Asher said he’s in good physical shape, and he’s worked around the public for a long time, so figures maybe that has strengthened his immune system. He’s always been careful about handwashing and said he’s perhaps a bit more conscious of germs than others might be.
Roselyn Mena, 68, a retired teacher in Richmond, Calif., about 16 miles northeast of San Francisco, said she’s managed to avoid the virus even though her husband, Jesus Mena, got infected, as did her two adult children. Now, she remains vigilant about wearing a mask. She tries not to eat inside at restaurants. “I’m super careful,” she said.
Besides her teacher training, Ms. Mena had training as a medical assistant and learned a lot about sanitizing methods. She gets an annual flu shot, washes her hands often, and uses hand sanitizer.
When she shops, she will ask salespeople not wearing masks to please mask. “Only one refused, and she got someone else [to wait on her].”
One reason she is always careful about hygiene, Ms. Mena said, is that “when I get a cold, I get really sick. It last and lasts.” Now, she does worry she might still get it, she said, with the prospect of getting long COVID driving that worry.
In the beginning of the pandemic, Rhonda Fleming, 68, of Los Angeles, lived in a “COVID bubble,” interacting with just a few close family members. As cases went down, she enlarged the bubble. Her two grown daughters got infected, but her granddaughter did not.
She has been vigilant about masking, she said, “and I do still mask in public places.” She has a mask wardrobe, including basic black as well as glittery masks for dressier occasions. “I always carry a mask because inevitably, a cougher surrounds me.”
Now, she will bypass restaurants if she doesn’t feel comfortable with the environment, choosing ones with good air flow. When she flew to Mexico recently, she masked on the plane.
At this point, she said she doesn’t worry about getting infected but remains careful.
Recently, two friends, who have been as diligent as she has about precautions, got infected, “and they don’t know how they got it.”
Bragging rights?
Until researchers separate out the true resisters from those who claim to be, some NOVIDs are simply quietly grateful for their luck, while others mention their COVID-free status to anyone who asks or who will listen, and are proud of it.
And what about those who wear a “NOVID” T-shirt?
“I would think they have a need to convey to the world they are different, perhaps special, because they beat COVID,” said Richard B. Joelson, a New York–based doctor of social work, a psychotherapist, and the author of Help Me! A Psychotherapist’s Tried-and-True Techniques for a Happier Relationship with Yourself and the People You Love. “They didn’t beat COVID, they just didn’t get it.”
Or they may be relieved they didn’t get sick, he said, because they feel defeated when they do. So “it’s a source of pride.” It might be the same people who tell anyone who will listen they never need a doctor or take no medicines, he said.
Even though science may prove many NOVIDs are inaccurate when they call themselves resisters, Dr. Hsieh understands the temptation to talk about it. “It’s kind of cool to think you are supernatural,” she said. “It’s much more attractive than being susceptible. It’s a lot sexier.” ■

The researchers have speculated that the inflammation characteristic of allergic conditions may reduce levels of a protein called the ACE2 receptor on the surface of airway cells. The SARS-CoV-2 virus uses the receptor to enter the cells, so if levels are low, that could reduce the ability of the virus to infect people.
The COVID Human Genetic Effort continues to search for participants, both those who were admitted to a hospital or repeatedly seen at a hospital because of COVID, as well as those who did not get infected, even after “intense and repeated” exposure.
The number of people likely to be resistant is much smaller, Dr. Hsieh said, than the number of people susceptible to severe disease.
The testing ... or lack thereof factor
The timing of testing and a person’s “infection profile” may be factors in people incorrectly declaring themselves NOVIDs, said Anne Wyllie, PhD, a research scientist in epidemiology at the Yale School of Public Health in New Haven, Conn., and a codeveloper of a saliva PCR test for COVID.
“Infection profiles can vary between individuals,” she said. For some, the infection may start in the lower respiratory tract, others in the higher respiratory tract. “Depending on where the virus takes up residence, that can affect test results.”
Then there’s the following-instructions factor. “It’s very likely that due to tests not being done at the right time, with the right sample, or not repeated if there is ongoing evidence of symptoms, that there are individuals out there who believe they are NOVIDs but just missed catching their infection at the window of opportunity.” Dr. Wyllie said.
Susceptibility research
“The part we have proven is the genetic defect that would make you more susceptible to having severe disease,” Dr. Hsieh said.
Many published papers report that inherited and/or autoimmune deficiencies of type I interferon immunity, important for combating viral infections and modulating the immune response, can be a significant cause of life-threatening COVID pneumonia.
More recently, researchers, including Jean-Laurent Casanova, MD, PhD, professor at Rockefeller University, New York, and cofounder of the COVID Human Genome Effort, reported that deficiencies in a gene that plays a role in built-in immunity (the early response), and a gene involved in signaling within the immune cells, impair interferon production and may be the basis of severe COVID pneumonia.
NOVIDs’ habits run the gamut
As scientists continue their research, the NOVIDs have their own ideas about why they’ve dodged the pandemic bullet, and they have a variety of approaches to handling the pandemic now.
Ryan Alexander, the field rep who travels to casinos, is up to date on his vaccinations and has gotten all the recommended COVID shots. “I was wearing a mask when told to wear masks,” he said.
He still observes the social distance habit but lives life. “I’ve been to three or four concerts in the past couple of years.”
And does he worry his number will eventually be up? “Not at this point, no,” he said.
Joe Asher, 46, said he has not gotten COVID despite being in contact with about 100 people a day, on average. He works as a bartender at an Evansville, Ind., brewery.
“On a Friday night, we can get 500 people,” he said. “I feel like almost everyone at the brewery got it. There’s no way I wasn’t exposed to it all the time.”
However, he said, his coworkers who did get sick were very cautious about not infecting others, partly to help protect a coworker’s family with newborn twins, so that may have helped him stay uninfected, too.
Mr. Asher said he’s in good physical shape, and he’s worked around the public for a long time, so figures maybe that has strengthened his immune system. He’s always been careful about handwashing and said he’s perhaps a bit more conscious of germs than others might be.
Roselyn Mena, 68, a retired teacher in Richmond, Calif., about 16 miles northeast of San Francisco, said she’s managed to avoid the virus even though her husband, Jesus Mena, got infected, as did her two adult children. Now, she remains vigilant about wearing a mask. She tries not to eat inside at restaurants. “I’m super careful,” she said.
Besides her teacher training, Ms. Mena had training as a medical assistant and learned a lot about sanitizing methods. She gets an annual flu shot, washes her hands often, and uses hand sanitizer.
When she shops, she will ask salespeople not wearing masks to please mask. “Only one refused, and she got someone else [to wait on her].”
One reason she is always careful about hygiene, Ms. Mena said, is that “when I get a cold, I get really sick. It last and lasts.” Now, she does worry she might still get it, she said, with the prospect of getting long COVID driving that worry.
In the beginning of the pandemic, Rhonda Fleming, 68, of Los Angeles, lived in a “COVID bubble,” interacting with just a few close family members. As cases went down, she enlarged the bubble. Her two grown daughters got infected, but her granddaughter did not.
She has been vigilant about masking, she said, “and I do still mask in public places.” She has a mask wardrobe, including basic black as well as glittery masks for dressier occasions. “I always carry a mask because inevitably, a cougher surrounds me.”
Now, she will bypass restaurants if she doesn’t feel comfortable with the environment, choosing ones with good air flow. When she flew to Mexico recently, she masked on the plane.
At this point, she said she doesn’t worry about getting infected but remains careful.
Recently, two friends, who have been as diligent as she has about precautions, got infected, “and they don’t know how they got it.”
Bragging rights?
Until researchers separate out the true resisters from those who claim to be, some NOVIDs are simply quietly grateful for their luck, while others mention their COVID-free status to anyone who asks or who will listen, and are proud of it.
And what about those who wear a “NOVID” T-shirt?
“I would think they have a need to convey to the world they are different, perhaps special, because they beat COVID,” said Richard B. Joelson, a New York–based doctor of social work, a psychotherapist, and the author of Help Me! A Psychotherapist’s Tried-and-True Techniques for a Happier Relationship with Yourself and the People You Love. “They didn’t beat COVID, they just didn’t get it.”
Or they may be relieved they didn’t get sick, he said, because they feel defeated when they do. So “it’s a source of pride.” It might be the same people who tell anyone who will listen they never need a doctor or take no medicines, he said.
Even though science may prove many NOVIDs are inaccurate when they call themselves resisters, Dr. Hsieh understands the temptation to talk about it. “It’s kind of cool to think you are supernatural,” she said. “It’s much more attractive than being susceptible. It’s a lot sexier.” ■

Factors linked with increased VTE risk in COVID outpatients
Though VTE risk is well studied and significant in those hospitalized with COVID, little is known about the risk in the outpatient setting, said the authors of the new research published online in JAMA Network Open.
The study was conducted at two integrated health care delivery systems in northern and southern California. Data were gathered from the Kaiser Permanente Virtual Data Warehouse and electronic health records.
Nearly 400,000 patients studied
Researchers, led by Margaret Fang, MD, with the division of hospital medicine, University of California, San Francisco, identified 398,530 outpatients with COVID-19 from Jan. 1, 2020, through Jan. 31, 2021.
VTE risk was low overall for ambulatory COVID patients.
“It is a reassuring study,” Dr. Fang said in an interview.
The researchers found that the risk is highest in the first 30 days after COVID-19 diagnosis (unadjusted rate, 0.58; 95% confidence interval, 0.51-0.67 per 100 person-years vs. 0.09; 95% CI, 0.08-0.11 per 100 person-years after 30 days).
Factors linked with high VTE risk
They also found that several factors were linked with a higher risk of blood clots in the study population, including being at least 55 years old; being male; having a history of blood clots or thrombophilia; and a body mass index (BMI) of at least 30 kg/m2.
The authors write, “These findings may help identify subsets of patients with COVID-19 who could benefit from VTE preventive strategies and more intensive short-term surveillance.”
Are routine anticoagulants justified?
Previously, randomized clinical trials have found that hospitalized patients with moderate COVID-19 may benefit from therapeutically dosed heparin anticoagulants but that therapeutic anticoagulation had no net benefit – and perhaps could even harm – patients who were critically ill with COVID.
“[M]uch less is known about the optimal thromboprophylaxis strategy for people with milder presentations of COVID-19 who do not require hospitalization,” they write.
Mild COVID VTE risk similar to general population
The authors note that rates of blood clots linked with COVID-19 are not much higher than the average blood clot rate in the general population, which is about 0.1-0.2 per 100 person-years.
Therefore, the results don’t justify routine administration of anticoagulation given the costs, inconvenience, and bleeding risks, they acknowledge.
Dr. Fang told this publication that it’s hard to know what to tell patients, given the overall low VTE risk. She said their study wasn’t designed to advise when to give prophylaxis.
Physicians should inform patients of their higher risk
“We should tell our patients who fall into these risk categories that blood clot is a concern after the development of COVID, especially in those first 30 days. And some people might benefit from increased surveillance,” Dr. Fang said.
”I think this study would support ongoing studies that look at whether selected patients benefit from VTE prophylaxis, for example low-dose anticoagulants,” she said.
Dr. Fang said the subgroup factors they found increased risk of blood clots for all patients, not just COVID-19 patients. It’s not clear why factors such as being male may increase blood clot risk, though that is consistent with previous literature, but higher risk with higher BMI might be related to a combination of inflammation or decreased mobility, she said.
Unanswered questions
Robert H. Hopkins Jr., MD, says the study helps answer a couple of important questions – that the VTE risk in nonhospitalized COVID-19 patients is low and when and for which patients risk may be highest.
However, there are several unanswered questions that argue against routine initiation of anticoagulants, notes the professor of internal medicine and pediatrics chief, division of general internal medicine, at University of Arkansas for Medical Sciences, Little Rock.
One is the change in the COVID variant landscape.
“We do not know whether rates of VTE are same or lower or higher with current circulating variants,” Dr. Hopkins said.
The authors acknowledge this as a limitation. Study data predate Omicron and subvariants, which appear to lower clinical severity, so it’s unclear whether VTE risk is different in this Omicron era.
Dr. Hopkins added another unknown: “We do not know whether vaccination affects rates of VTE in ambulatory breakthrough infection.”
Dr. Hopkins and the authors also note the lack of a control group in the study, to better compare risk.

Adherence to DASH diet reduced risk of COPD
Greater adherence to the Dietary Approaches to Stop Hypertension (DASH) diet was associated with a significantly reduced risk of chronic obstructive pulmonary disease (COPD) and improved lung function, based on data from more than 28,000 individuals in the United States.
but the effects of specific diet models such as the DASH diet and Mediterranean diet on COPD in particular has not been well studied, Jingli Wen, MD, of Nanjing Medical University, Jiangsu, China, and colleagues wrote.
In a study published in Frontiers in Nutrition, the researchers reviewed data from 28,605 adult participants in the National Health and Nutrition Examination Survey from 1999 to 2018.
The study population included 2,488 individuals with COPD participants and 25,607 individuals without COPD; the mean ages of the COPD and non-COPD groups were 60.2 years and 56.9 years, and the proportion of women was 63.7% and 51.4%, respectively. The primary outcome was the prevalence of COPD, defined as self-reports of a diagnosis of chronic bronchitis or emphysema. DASH diet scores were based on consumption of nine target nutrients: saturated fat, total fat, protein, cholesterol, fiber, magnesium, calcium, potassium, and sodium. Scores for compliance with the Mediterranean diet were based on intake of eight food categories: fruits, vegetables, legumes, fish, red meat, dairy products, alcohol, and olive oil.
Overall, a higher score for adherence to the DASH diet was significantly associated with a lower COPD risk (odds ratio, 0.83; P = .021). This association remained significant in subgroups of younger adults (OR, 0.74), men (OR, 0.73), and smokers (OR, 0.82).
By contrast, adherence to the Mediterranean diet was not significantly associated with COPD prevalence (OR, 1.03; P = .697).
The researchers also found a correlation between DASH diet adherence and improved lung function, especially among individuals without COPD. The risk of FEV1: forced vital capacity decrease, as well as dyspnea, cough, and expectoration, were negatively associated with greater adherence to the DASH diet, but greater adherence to the Mediterranean diet was only negatively associated with cough risk.
The relationship between the DASH diet and reduced COPD risk persisted after adjusting for occupational exposure and excluding participants with cardiovascular disease, cancer, or diabetes.
The current study is the first known to focus on the association between DASH diet and the risk of COPD among adults in the United States, the researchers wrote. The lack of effect of the Mediterranean diet on COPD, in contrast to some studies in other countries, “suggests that regional differences in diet may affect the role of diet in the development of COPD.”
The study findings were limited by several factors including the cross-sectional design that prevented conclusions of causality, the researchers noted. Other limitations included the lack of data of the impact of poor living habits, such as smoking, on food decisions, the use of short-term 24-hour dietary recall, and the reliance of self-reports for a diagnosis of COPD.
However, the results support the role of diet in COPD pathogenesis and expand the knowledge of relationships between the DASH diet and major chronic diseases, the researchers said. More prospective studies and clinical intervention studies are needed, but the findings should encourage clinicians to consider the potential role of a healthy diet in promoting lung health.

Gestational diabetes affects fetal lung development
Lung development in the fetus may be adversely affected by a mother’s gestational diabetes, based on data from in vivo, in vitro, and ex vivo studies.
Gestational diabetes mellitus (GDM) has recently been associated with fetal lung underdevelopment (FLUD) and delayed lung maturation that may lead to immediate respiratory distress in newborns and later chronic lung disease, Pengzheng Chen, PhD, of Shandong University, Jinan, China, and colleagues wrote.
Antenatal corticosteroids are considered an effective treatment for gestational fetal lung underdevelopment, but recent studies have shown adverse effects of these medications, and therefore more research is needed to identify the etiology and pathogenesis of FLUD induced by GDM, they said.
In a study published in the International Journal of Nanomedicine, the researchers collected umbilical cord blood samples from patients with GDM and matched controls at a single hospital in China.
“Using an ex vivo exosome exposure model of fetal lung explants, we observed the morphological alteration of lung explants and evaluated the expression of molecules involved in lung development,” the researchers wrote.
Fetal lung underdevelopment was more common after exposure to exosomes from the umbilical cord plasma of individuals with gestational diabetes mellitus, compared with exosomes from healthy controls.
The researchers also used mouse models to examine the effects of exosomes on fetal lung development in vivo. They found that exosomes associated with GDM impeded the growth, branching morphogenesis, and maturation of fetal lungs in mouse models. In addition, the expression of the apoptotic biomarkers known as BAX, BIM, and cleaved CASPASE-3 was up-regulated in GDMUB-exosomes and HG-exos groups, but the antiapoptotic protein BCL-2 was down-regulated; this further supported the negative impact of GDM exomes on fetal lung development, the researchers said.
The researchers then conducted miRNA sequencing, which showed that the miRNA in placenta-derived exosomes from GDM pregnancies were distinct from the miRNA in exosomes from healthy control pregnancies.
The study findings were limited by several factors including the impurity of the isolated placenta-derived exosomes from the umbilical cord blood plasma, which were not placenta specific, the researchers noted. Other limitations included the lack of data on different stages of lung development, and more research is needed to validate miRNAs and to explore the signally pathways involved in fetal lung development.
However, the study is the first known to demonstrate an adverse effect of GDM on fetal lung development via in vitro, ex vivo, and in vitro models, they said.
“These data highlight an emerging role of placenta-derived exosomes in the pathogenesis of fetal lung underdevelopment in GDM pregnancies, and provide a novel strategy for maternal-fetal communication,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.

Fetal lung underdevelopment was more common after exposure to exosomes from the umbilical cord plasma of individuals with gestational diabetes mellitus, compared with exosomes from healthy controls.
The researchers also used mouse models to examine the effects of exosomes on fetal lung development in vivo. They found that exosomes associated with GDM impeded the growth, branching morphogenesis, and maturation of fetal lungs in mouse models. In addition, the expression of the apoptotic biomarkers known as BAX, BIM, and cleaved CASPASE-3 was up-regulated in GDMUB-exosomes and HG-exos groups, but the antiapoptotic protein BCL-2 was down-regulated; this further supported the negative impact of GDM exomes on fetal lung development, the researchers said.
The researchers then conducted miRNA sequencing, which showed that the miRNA in placenta-derived exosomes from GDM pregnancies were distinct from the miRNA in exosomes from healthy control pregnancies.
The study findings were limited by several factors including the impurity of the isolated placenta-derived exosomes from the umbilical cord blood plasma, which were not placenta specific, the researchers noted. Other limitations included the lack of data on different stages of lung development, and more research is needed to validate miRNAs and to explore the signally pathways involved in fetal lung development.
However, the study is the first known to demonstrate an adverse effect of GDM on fetal lung development via in vitro, ex vivo, and in vitro models, they said.
“These data highlight an emerging role of placenta-derived exosomes in the pathogenesis of fetal lung underdevelopment in GDM pregnancies, and provide a novel strategy for maternal-fetal communication,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.
Lung development in the fetus may be adversely affected by a mother’s gestational diabetes, based on data from in vivo, in vitro, and ex vivo studies.
Gestational diabetes mellitus (GDM) has recently been associated with fetal lung underdevelopment (FLUD) and delayed lung maturation that may lead to immediate respiratory distress in newborns and later chronic lung disease, Pengzheng Chen, PhD, of Shandong University, Jinan, China, and colleagues wrote.
Antenatal corticosteroids are considered an effective treatment for gestational fetal lung underdevelopment, but recent studies have shown adverse effects of these medications, and therefore more research is needed to identify the etiology and pathogenesis of FLUD induced by GDM, they said.

‘Unheard of’ PAH improvement with novel drug: STELLAR
NEW ORLEANS – An investigational, first-in class agent that delivers a completely new type of intervention to patients with pulmonary arterial hypertension (PAH) scored a clear win in the STELLAR trial, the first to complete among three phase 3 trials that are testing this agent.
Sotatercept, administered subcutaneously every 3 weeks for 24 weeks, improved from baseline average 6-minute walk distance (6MWD) by a significant and clinically meaningful 40.8 meters, compared with placebo, for the trial’s primary efficacy endpoint (P < .001). The treatment also “delivered broad clinical benefit across multiple domains including hemodynamics, World Health Organization functional class, disease biomarkers, risk scores and patient-reported outcomes,” Marius M. Hoeper, MD, said at the joint scientific sessions of the American College of Cardiology and the World Heart Federation.
“These results establish the clinical utility of sotatercept, administered in combination with approved PAH therapies, as a new treatment for PAH,” added Dr. Hoeper, professor and deputy director of the department of respiratory medicine at Hannover (Germany) Medical School,
“The most important aspect was the hemodynamic improvement,” with sotatercept treatment, which led to an average 235 dyn/sec per cm−5 reduction in pulmonary vascular resistance from baseline and an average cut in pulmonary artery pressure of 13.9 mm Hg from baseline, compared with placebo, a result that’s “unheard of,” Dr. Hoeper said in a press conference during the meeting.
“With other tested agents we usually see very little improvement in pulmonary artery pressure. This is a signal that we achieved some reversing of the pathological changes in the pulmonary vessels that lead to” PAH, he added.
Simultaneously with his report the findings also appeared online in the New England Journal of Medicine.
‘A new hope’ for patients with PAH
Based on the reported findings, sotatercept is a “very exciting boutique molecule” that will “offer patients with PAH a very exciting new treatment,” commented Rhonda Cooper-DeHoff, PharmD, a designated discussant and a researcher at the University of Florida, Gainesville.
“This study is a new hope for patients with PAH. Until now, they’ve had really bad outcomes, but [in this study] we see significant differences in 6MWD, hemodynamics, and risk factors. Overall, I think the benefit is greater than the risk” it may pose to patients through potential adverse effects, commented Julia Grapsa, MD, PhD, a cardiologist at St. Thomas Hospital in London, and another discussant at the meeting.
“The results are impressive” and “encouraging,” and “suggest that sotatercept may represent a new and clinically consequential addition to current medications for PAH,” wrote three clinicians from Canyons Region Intermountain Medical Center in Murray, Utah, in an editorial that accompanied the published report.
But the authors of the editorial also raised several cautions and concerns. They questioned the generalizability of the findings, noting that the patients with PAH enrolled in the study were all adults who were clinically stable and an average of more than 8 years out from their initial PAH diagnosis, and more than 90% were on stable treatment for PAH with two or three agents specific for treating the disorder. The study cohort also had a disproportionately high enrollment of patients with idiopathic (59%) or heritable (18%) forms of PAH, and the 15% of patients in the trial with connective tissue disease represented a disproportionately low prevalence of this PAH subtype.
The editorialists also called for “ongoing vigilance” for adverse effects from sotatercept treatment, although they acknowledged that the adverse effects reported to date from sotatercept are “largely reassuring.”
Death or clinical worsening cut by 84%
STELLAR randomized 323 patients at 91 sites in 21 countries with WHO Group 1 PAH and with WHO functional class II or III disease to receive either sotatercept or placebo for 24 weeks, with an option for treatment to continue beyond that until the last patient in the study reached 24 weeks on treatment, resulting in an overall median treatment duration of nearly 33 weeks.
In addition to the significant result for the primary endpoint, the 163 patients who received sotatercept had significant improvements, compared with 160 placebo-treated patients, for eight of nine secondary endpoints. The only secondary endpoint with a neutral result was for a measure of cognitive and emotional wellbeing, a parameter that was already at a normal level at baseline in most enrolled patients, Dr. Hoeper explained.
The incidence of either death or an event indicative of clinical worsening during the overall median follow-up of almost 33 weeks was 26.3% among the control patients and 5.5% among those who received sotatercept. This translated into a significant reduction for this endpoint of 84% with sotatercept treatment, compared with placebo.
The rates of treatment-emergent adverse events leading to discontinuation were roughly the same in the control and sotatercept arms, and the incidence of severe or serious treatment-emergent adverse events was higher among the control patients.
The most common adverse event on sotatercept was bleeding events, which occurred in 32% of those on sotatercept and in 16% of the control patients, but the events in the sotatercept arm were “mostly mild,” said Dr. Hoeper. The next most frequent adverse event during sotatercept treatment was appearance of telangiectasias, which occurred in 14% of those on sotatercept and in 4% of control patients.
“It’s an uncommon adverse event profile, but not unexpected for a drug with its mechanism of action,” he said.
Drug binds activin, a pathologic driver of PAH
Sotatercept is an engineered molecule that combines a section of a human immunoglobulin G molecule with a portion of the receptor for activin. This structure allows sotatercept to bind free activin molecules in a patient’s blood, thereby removing a key driver of the pulmonary vascular wall remodeling that is at the pathologic root of PAH.
“Hyperproliferation of blood vessel–wall cells” caused by activin signaling “is perhaps the most important driver of PAH,” Dr. Hoeper said. “Sotatercept allows us for the first time to target the underlying mechanism behind PAH.”
Still ongoing are the HYPERION and ZENITH phase 3 trials of sotatercept. HYPERION is enrolling patients with newly diagnosed or high-risk PAH and is expected to complete in 2028. ZENITH is enrolling patients with more advanced PAH and a higher mortality risk, with results expected in 2026.
Sotatercept has received “Breakthrough Therapy” designation and “Orphan Drug” designation by the Food and Drug Administration, and “Priority Medicines” designation and “Orphan Drug” designation by the European Medicines Agency for the treatment of PAH. One recent review estimated a worldwide PAH prevalence of about 3-4 cases/100,000, which for the United States translates into a total prevalence of perhaps 10,000-15,000 affected people.
STELLAR was funded by Acceleron Pharma, a subsidiary of Merck. Dr. Hoeper is a consultant to Acceleron. Dr. Cooper-DeHoff, Dr. Grapsa, and the authors of the editorial on STELLAR have no relevant disclosures.
