When I read the news that Bruce Willis had disclosed his diagnosis of frontotemporal dementia (FTD), I was reminded that all of us are at risk for spending our final epoch lost in a neurologic swamp. What is remarkable about the swamp that we call FTD is that it’s a somewhat rare and unusual type of dementia. We tend to characterize dementia as the erosion of memory, but FTD is more characterized by the loss of control over emotions and other cognitive functions. What›s especially tragic for performers like Mr. Willis is the loss of the verbal fluency required for delivering one’s lines.

Frontotemporal dementia

To this casual observer, Bruce Willis was an almost invincible force, vigorous, vital, one of the “immortals.” Alas, with his FTD diagnosis, we know that even a die-hard like Mr. Willis, now only 67 years of age, may have to endure years of progressive decline. If the disease follows its typical path, that will probably include slowly disconnecting and progressively losing emotional judgment and control as well as losing a reasonable understanding of what or why any of it is happening. He may also experience a progressive deterioration of the control of bodily functions and general health.

Most people with dementia lose their neurocognitive abilities through a number of different pathways, all of which result in brain shrinkage, disconnection, evident neuropathology, neurobehavioral expressions of loss, and forms of befuddlement. Alzheimer’s disease leads the list as the most common form of dementia, but vascular dementias; dementia with Lewy bodies; “mixed” dementias; dementias associated with Parkinson’s, Huntington’s, or other diseases; dementia rising from alcoholic or other brain poisoning, HIV, Lyme disease, or a host of other brain infections; or from traumatic encephalopathy (chronic or more current) may present at any active neurology clinic. These are what you might think of as your “grandpa’s dementia” – the common types often associated with old age.

FTD is a particularly interesting variant for several reasons. First, it usually arises in relatively young individuals, with initial symptoms emerging in one’s 50s or 60s. In most cases, there is no genetic and, with rare exception, any other explanation of origin – except that old medical standby, bad luck.

Second, FTD has little initial impact on a patient’s broader memory and associated cognitive abilities. The patient will stumble to come up with that next word and ultimately slow down their speech as their brain struggles with verbal fluency; they will struggle with translating their feelings and emotions into fast and appropriate actions expressed in their mind and their physical body while their memory will appear intact.

In all other dementias, cognitive losses can be profound, whereas social and emotional control and voluble speech production are generally better sustained. Imagine the impact that these struggles in verbal fluency and in emotional calibration and response must have for an established actor. By all reports, Mr. Willis vigorously pursued the work that he loved right up until the time of his dementia diagnosis, even as his colleagues would almost certainly have seen that he was struggling. Sadly, a lack of that type of self-awareness is an expected consequence of FTD.
 

The salience network and von Economo neurons

Third and most intriguing to a neuroscientific nerd like me is that patients with FTD experience an initial loss of a special population of cortical neurons located within the salience network in our brains, called the von Economo neurons. That salience network is designed to quickly read and evaluate our complex thoughts and emotions and via those Economo neurons, initiate appropriate neurologic and physical responses.

We share this special von Economo machinery with great apes, whales, elephants, and a handful of other especially social mammalian species.

When we see or hear or otherwise sense something that induces fear, alarm, or a potential reward, the salience network in our brain acts as a kind of gatekeeper. First, it assesses the emergent or changing situation, then it rapidly initiates an emotional and physical response. As I sit with a patient in obvious distress in my office, my salience network turns on an empathetic alarm. My brain and body immediately adjust to initiate appropriately sympathetic reactions. The von Economo neurons – those very neurons that have substantially died off in a brain with FTD – are the linchpins in this fast-response emotion and complex body signal-informed system.

Controlled emotional response is at the heart of our humanity. It’s a sad day when we lose it.

In other neurologic clinical conditions marked by the loss of specific brain cells, different forms of “disuse atrophy” are partly the cause. We don’t know whether that’s the case for FTD. Scientists have shown that specific forms of computerized brain exercises can sharply increase activity levels in the salience network which is linked to improvements in the regulatory control of the autonomic nervous system – one of the key response-mediating targets of the network’s von Economo neurons.

Interestingly, superagers who sustain body and brain health into their 90s (and beyond) die with a full complement of von Economo neurons operating happily in a still-vigorous salience network.

This neuroscientist can foresee a day when we routinely assess the integrity of this important brain system and more reliably maintain its good health. Keeping those very special neurons alive would have probably allowed Mr. Willis to sustain himself on the soundstage and on the grander stage of life for a long time to come. Alas, like so many things in medicine, there is promise. But at this moment for this famous patient, our current medical science appears to be a day late, and a dollar short.

Dr. Merzenichis is professor emeritus at the University of California, San Francisco, and a Kavli Laureate in Neuroscience. He reported conflicts of interest with the National Institutes of Health, Stronger Brains, and Posit Science.

“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. The recommended amount of weekly physical activity is 2.5 hours (150 minutes), but less than half of adults over 18 meet the guidelines for aerobic 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.”

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.”

DENVER – People with lower expectations of how they would be able to use their knees during work activities after a total knee arthroplasty were more dissatisfied with their knee abilities 6 months after their surgery, according to a study presented at the OARSI 2023 World Congress.

Two out of 10 patients are dissatisfied after total knee arthroplasty, which is increasingly performed in younger and working patients who may have higher demands, presenter Yvonne van Zaanen, a physiotherapist in occupational health and ergonomics and a PhD candidate at Amsterdam University Medical Center, told attendees.

The findings suggest a correlation between patients’ low presurgical expectations of their ability to use their knees and having more difficulty with their knees postoperatively, she said. “We should take better care of working patients with low expectations by managing their preoperative expectations and improving their ability to perform work-related knee-straining activities in rehabilitation,” Ms. van Zaanen told attendees.

The researchers conducted a multicenter, prospective cohort study involving seven hospitals. They surveyed 175 employed individuals aged 18-65 years who were scheduled for a total knee arthroplasty and intended to return to work after their surgery. The first survey occurred before the operation, and the follow-up occurred 6 months after the surgery.

Just over half the participants were women (53%), and the average participant age was 59. Respondents had a mean body mass index (BMI) of 29 kg/m², and had a Knee injury and Osteoarthritis Outcome Score (KOOS) pain score of 42 (on a 0-to-100 scale in which lower scores are worse). About half the respondents (51%) had a job that involved knee-straining activities.

The researchers assessed participants’ ability to perform work-related, knee-straining activities using the Work, Osteoarthritis, or joint-Replacement Questionnaire (WORQ) tool, which considers the following activities: kneeling, crouching, clambering, taking the stairs, walking on rough terrain, working with hands below knee height, standing, lifting or carrying, pushing or pulling, walking on ground level, operating a vehicle, operating foot pedals, and sitting. The 0-to-100 scale rates the difficulty of using knees for each particular activity, with higher scores indicating greater ease and less pain in doing that activity.

Among the 107 patients who expected to be satisfied after their surgery, half (n = 53) were satisfied, compared with 12% (n = 13) who were unsatisfied; the remaining participants (n = 41, 38%) were neither satisfied nor dissatisfied. Among the 24 patients who expected to be dissatisfied after their surgery, one-third (n = 8) were satisfied and 42% (n = 10) were dissatisfied. The remaining 44 patients didn’t expect to be satisfied or dissatisfied before their surgery, and 41% of them were satisfied while 23% were dissatisfied.

The researchers found that patients’ expectation of their satisfaction level going into the surgery was the only preoperative factor to be prognostic for dissatisfaction 6 months after surgery, based on their WORQ score. That is, patients who expected to be dissatisfied before their surgery had approximately five times greater odds of being dissatisfied after their surgery than did those who expected to be satisfied with their ability to do knee-straining activities at work (odds ratio, 5.1; 95% confidence interval, 1.7-15.5). Among those with a WORQ score of 40, indicating a greater expectation of difficulty using their knees postoperatively, 55% were dissatisfied after their surgery, compared with 19% of those with a WORQ score of 85, who expected greater knee ability after their surgery.

The other factors that the researchers examined, which had no effect on WORQ scores, included age, sex, BMI, education, comorbidities, KOOS pain subscale, having a knee-straining job, having needed surgery because of work, or having preoperative sick leave.

One discussion prompted by the presentation focused specifically on individuals’ ability to kneel without much difficulty after their surgery, an activity that’s not typically considered likely, Ms. van Zaanen noted. One audience member, Gillian Hawker, MD, MSc, a professor of medicine in the division of rheumatology at the University of Toronto, questioned whether the field should accept that current reality from surgical intervention. Dr. Hawker described a cohort she had analyzed in which two-thirds of the participants had expected they would be able to kneel after their surgery, regardless of whether it was related to work or other activities.

“Kneeling is important, not just for work; it’s important for culture and religion and lots of other things,” Dr. Hawker said. “How will you help these people to kneel after knee replacement when the surgery isn’t really performed to enable people to do that?” In response, Ms. van Zaanen noted it might not be achievable, as the research literature demonstrates, but Dr. Hawker suggested that is itself problematic.

“I guess what I’m asking is, why are we settling for that? If it’s important to so many people, and an expectation of so many people, why don’t we technologically improve such that, post arthroplasty, people can kneel?”

Another commenter suggested that the study’s findings may not indicate a need to manage patients’ expectations prior to surgery so much as showing that some patients simply have realistic expectations of what they will and will not be able to do after knee replacement.

“Is it possible that people who had low expectations – those who expected to be dissatisfied afterwards – were appropriately understanding that they were likely to be dissatisfied afterwards, in which case, managing their expectations might do nothing for their dissatisfaction afterwards?” the commenter asked. It is likely necessary to conduct additional research about expectations before surgery and experiences after surgery to address that question, Ms. van Zaanen suggested.

Ms. van Zaanen and Dr. Hawker reported having no relevant financial relationships. The presentation did not note any external funding. The Congress was sponsored by the Osteoarthritis Research Society International.

Almost three-quarters of adults living in the United States report having never tested for HIV according to a newly published study from the Centers for Disease Control and Prevention. The reasons are complex and could jeopardize goals of ending the AIDS epidemic by 2030.

Patients and doctors alike face system challenges, including stigma, confidentiality concerns, racism, and inequitable access. Yet doctors, public health authorities, and even some patients agree that testing does work: In 2022, 81% of people diagnosed with HIV were linked to care within 30 days. Moreover, many patients are aware of where and how they wish to be tested. So, what would it take to achieve what ostensibly should be the lowest hanging fruit in the HIV care continuum?

“We didn’t look at the reasons for not testing,” Marc Pitasi, MPH, CDC epidemiologist and coauthor of the CDC study said in an interview. But “we found that the majority of people prefer the test in a clinical setting, so that’s a huge important piece of the puzzle,” he said.

The “never-tested” populations (4,334 of 6,072) in the study were predominantly aged 18-29 years (79.7%) and 50 years plus (78.1%). A total of 48% of never-tested adults also indicated that they had engaged in past-year risky behaviors (that is, injection drug use, treated for a sexually transmitted disease, exchanged sex/drugs for money, engaged in condomless anal sex, or had more than four sex partners). However, the difference between never-tested adults who live in EHE (Ending the HIV Epidemic in the U.S.)–designated jurisdictions (comprising 50 areas and 7 U.S. states responsible for more than 50% of new HIV infections) and those residing in non-EHE areas was only about 5 percentage points (69.1% vs. 74.5%, respectively), underscoring the need for broader engagement.

“There’s definitely a lack of testing across the board,” explained Lina Rosengren-Hovee, MD, MPH, MS, an infectious disease epidemiologist at the University of North Carolina at Chapel Hill. “There are all sorts of biases on how we make decisions and how we stratify … and these heuristics that we have in our minds to identify who is at risk and who needs testing,” she said.

“If we just look at the need for HIV testing based on who is at risk, I think that we are always going to fall short.”
 

Conflicting priorities

Seventeen years have passed since the CDC recommended that HIV testing and screening be offered at least once to all people aged 13-64 years in a routine clinical setting, with an opt-out option and without a separate written consent. People at higher risk (sexually active gay, bisexual, and other men who have sex with men) should be rescreened at least annually.

These recommendations were subsequently reinforced by numerous organizations, including the U.S. Preventive Services Task Force in 2013 and again in 2019, and the American Academy of Pediatrics in 2021.

But Dr. Rosengren-Hovee said that some clinicians remain unaware of the guidelines; for others, they’re usually not top-of-mind because of conflicting priorities.

This is especially true of pediatricians, who, despite data demonstrating that adolescents account for roughly 21% of new HIV diagnoses, rarely recognize or take advantage of HIV-testing opportunities during routine clinical visits.

“Pediatricians want to do the right thing for their patients but at the same time, they want to do the right thing on so many different fronts,” said Sarah Wood, MD, of the University of Pennsylvania, Philadelphia, and attending physician of adolescent medicine at Children’s Hospital of Philadelphia.

Dr. Wood is coauthor of a study published in Implementation Science Communicationsexamining pediatrician perspectives on implementing HIV testing and prevention. Participants identified confidentiality and time constraints as the most important challenges across every step of their workflow, which in turn, influenced perceptions about patients’ perceived risks for acquiring HIV – perceptions that Dr. Wood believes can be overcome.

“We need to really push pediatricians (through guideline-making societies like AAP and USPSTF) that screening should be universal and not linked to sexual activity or pinned to behavior, so the offer of testing is a universal opt-out,” she said. Additionally, “we need to make it easier for pediatricians to order the test,” for example, “through an office rapid test … and a redesigned workflow that moves the conversation away from physicians and nurse practitioners to medical assistants.”

Dr. Wood also pointed out that any effort would require pediatricians and other types of providers to overcome discomfort around sexual health conversations, noting that, while pediatricians are ideally positioned to work with parents to do education around sexual health, training and impetus are needed.
 

A fractured system

A fractured, often ill-funded U.S. health care system might also be at play according to Scott Harris, MD, MPH, state health officer of the Alabama Department of Public Health in Montgomery, and Association of State and Territorial Health Officials’ Infectious Disease Policy Committee chair.

“There’s a general consensus among everyone in public health that [HIV testing] is an important issue that we’re not addressing as well as we’d like to,” he said.

Dr. Harris acknowledged that, while COVID diverted attention away from HIV, some states have prioritized HIV more than others.

“We don’t have a national public health program; we have a nationwide public health program,” he said. “Everyone’s different and has different responsibilities and authorities ... depending on where their funding streams come from.”

The White House recently announced that it proposed a measure in its Fiscal Year 2023 budget to increase funding for HIV a further $313 million to accelerate efforts to end HIV by 2030, also adding a mandatory program to increase preexposure prophylaxis (PrEP) access. Without congressional approval, the measures are doomed to fail, leaving many states without the proper tools to enhance existing programs, and further painting overworked clinicians into a corner.

For patients, the ramifications are even greater.

“The majority of folks [in the CDC study] that were not tested said that if they were to get tested, they’d prefer to do that within the context of their primary care setting,” said Justin C. Smith, MS, MPH, director of the Campaign to End AIDS, Positive Impact Health Centers; a behavioral scientist at Emory University’s Rollins School of Public Health in Atlanta; and a member of the Presidential Advisory Council on HIV/AIDS.

“When you create a more responsive system that really speaks to the needs that people are expressing, that can provide better outcomes,” Dr. Smith said.

“It’s vital that we create health care and public health interventions that change the dynamics ... and make sure that we’re designing systems with the people that we’re trying to serve at the center.”

Mr. Pitasi, Dr. Rosengren-Hovee, Dr. Wood, Dr. Harris, and Dr. Smith have disclosed no relevant financial relationships.

Yet doctors, public health authorities, and even some patients agree that testing does work: In 2022, 81% of people diagnosed with HIV were linked to care within 30 days. Moreover, many patients are aware of where and how they wish to be tested. So, what would it take to achieve what ostensibly should be the lowest hanging fruit in the HIV care continuum?

“We didn’t look at the reasons for not testing,” Marc Pitasi, MPH, CDC epidemiologist and coauthor of the CDC study said in an interview. But “we found that the majority of people prefer the test in a clinical setting, so that’s a huge important piece of the puzzle,” he said.

The “never-tested” populations (4,334 of 6,072) in the study were predominantly aged 18-29 years (79.7%) and 50 years plus (78.1%). A total of 48% of never-tested adults also indicated that they had engaged in past-year risky behaviors (that is, injection drug use, treated for a sexually transmitted disease, exchanged sex/drugs for money, engaged in condomless anal sex, or had more than four sex partners). However, the difference between never-tested adults who live in EHE (Ending the HIV Epidemic in the U.S.)–designated jurisdictions (comprising 50 areas and 7 U.S. states responsible for more than 50% of new HIV infections) and those residing in non-EHE areas was only about 5 percentage points (69.1% vs. 74.5%, respectively), underscoring the need for broader engagement.

“There’s definitely a lack of testing across the board,” explained Lina Rosengren-Hovee, MD, MPH, MS, an infectious disease epidemiologist at the University of North Carolina at Chapel Hill. “There are all sorts of biases on how we make decisions and how we stratify … and these heuristics that we have in our minds to identify who is at risk and who needs testing,” she said.

“If we just look at the need for HIV testing based on who is at risk, I think that we are always going to fall short.”
 

Conflicting priorities

Seventeen years have passed since the CDC recommended that HIV testing and screening be offered at least once to all people aged 13-64 years in a routine clinical setting, with an opt-out option and without a separate written consent. People at higher risk (sexually active gay, bisexual, and other men who have sex with men) should be rescreened at least annually.

These recommendations were subsequently reinforced by numerous organizations, including the U.S. Preventive Services Task Force in 2013 and again in 2019, and the American Academy of Pediatrics in 2021.

But Dr. Rosengren-Hovee said that some clinicians remain unaware of the guidelines; for others, they’re usually not top-of-mind because of conflicting priorities.

This is especially true of pediatricians, who, despite data demonstrating that adolescents account for roughly 21% of new HIV diagnoses, rarely recognize or take advantage of HIV-testing opportunities during routine clinical visits.

“Pediatricians want to do the right thing for their patients but at the same time, they want to do the right thing on so many different fronts,” said Sarah Wood, MD, of the University of Pennsylvania, Philadelphia, and attending physician of adolescent medicine at Children’s Hospital of Philadelphia.

Dr. Wood is coauthor of a study published in Implementation Science Communicationsexamining pediatrician perspectives on implementing HIV testing and prevention. Participants identified confidentiality and time constraints as the most important challenges across every step of their workflow, which in turn, influenced perceptions about patients’ perceived risks for acquiring HIV – perceptions that Dr. Wood believes can be overcome.

“We need to really push pediatricians (through guideline-making societies like AAP and USPSTF) that screening should be universal and not linked to sexual activity or pinned to behavior, so the offer of testing is a universal opt-out,” she said. Additionally, “we need to make it easier for pediatricians to order the test,” for example, “through an office rapid test … and a redesigned workflow that moves the conversation away from physicians and nurse practitioners to medical assistants.”

Dr. Wood also pointed out that any effort would require pediatricians and other types of providers to overcome discomfort around sexual health conversations, noting that, while pediatricians are ideally positioned to work with parents to do education around sexual health, training and impetus are needed.
 

A fractured system

A fractured, often ill-funded U.S. health care system might also be at play according to Scott Harris, MD, MPH, state health officer of the Alabama Department of Public Health in Montgomery, and Association of State and Territorial Health Officials’ Infectious Disease Policy Committee chair.

“There’s a general consensus among everyone in public health that [HIV testing] is an important issue that we’re not addressing as well as we’d like to,” he said.

Dr. Harris acknowledged that, while COVID diverted attention away from HIV, some states have prioritized HIV more than others.

“We don’t have a national public health program; we have a nationwide public health program,” he said. “Everyone’s different and has different responsibilities and authorities ... depending on where their funding streams come from.”

The White House recently announced that it proposed a measure in its Fiscal Year 2023 budget to increase funding for HIV a further $313 million to accelerate efforts to end HIV by 2030, also adding a mandatory program to increase preexposure prophylaxis (PrEP) access. Without congressional approval, the measures are doomed to fail, leaving many states without the proper tools to enhance existing programs, and further painting overworked clinicians into a corner.

For patients, the ramifications are even greater.

“The majority of folks [in the CDC study] that were not tested said that if they were to get tested, they’d prefer to do that within the context of their primary care setting,” said Justin C. Smith, MS, MPH, director of the Campaign to End AIDS, Positive Impact Health Centers; a behavioral scientist at Emory University’s Rollins School of Public Health in Atlanta; and a member of the Presidential Advisory Council on HIV/AIDS.

“When you create a more responsive system that really speaks to the needs that people are expressing, that can provide better outcomes,” Dr. Smith said.

“It’s vital that we create health care and public health interventions that change the dynamics ... and make sure that we’re designing systems with the people that we’re trying to serve at the center.”

Mr. Pitasi, Dr. Rosengren-Hovee, Dr. Wood, Dr. Harris, and Dr. Smith have disclosed no relevant financial relationships.

A nationwide shortage of liquid albuterol is having minimal impact on patient care, as treatment alternatives are available, and supply appears to be recovering fast, suggest accounts from experts at health care centers around the country.

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.

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.”

National Jewish Health

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.”

Michican Medicine

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.

University of Pittsburgh School of Medicine

“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.

Until just over a year ago, Pat Trueman, an 82-year-old in New Hampshire, had always been a “go-go-go” kind of person. Then she started feeling tired easily, even while doing basic housework.

“I had no stamina,” Ms. Trueman said. “I didn’t feel that bad, but I just couldn’t do anything.” She had also begun noticing black and blue bruises appearing on her body, so she met with her cardiologist. But when switching medications and getting a pacemaker didn’t rid Ms. Trueman of the symptoms, her doctor referred her to a hematologist oncologist.

A bone marrow biopsy eventually revealed that Ms. Trueman had myelodysplastic neoplasms, or MDS, a blood cancer affecting an estimated 60,000-170,000 people in the United States, mostly over age 60. MDS includes several bone marrow disorders in which the bone marrow does not produce enough healthy, normal blood cells. Cytopenias are therefore a key feature of MDS, whether it’s anemia (in Ms. Trueman’s case), neutropenia, or thrombocytopenia.

Jamie Koprivnikar, MD, a hematologist oncologist at Hackensack (N.J) University Medical Center, describes the condition to her patients using a factory metaphor: “Our bone marrow is the factory where the red blood cells, white blood cells, and platelets are made, and MDS is where the machinery of the factory is broken, so the factory is making defective parts and not enough parts.”

The paradox of MDS is that too many cells are in the bone marrow while too few are in the blood, since most in the marrow die before reaching the blood, explained Azra Raza, MD, a professor of medicine and director of the MDS Center at Columbia University Medical Center, New York, and author of The First Cell (New York: Basic Books, 2019).

Although MDS is not rare, the condition has seen remarkably few new therapies in recent years. Most are either improvements on an existing treatment – such as an oral formulation of an infused drug – or a drug borrowed from therapies for other blood cancers, particularly acute myeloid leukemia (AML).

“We’re looking at taking a lot of the therapies that we’ve used to treat AML and then trying to apply them to MDS,” Dr. Koprivnikar said. “With all the improvement that we’re seeing there with leukemia, we’re definitely expecting this trickle-down effect to also help our high-risk MDS patients.”
 

Workup begins with risk stratification

While different types of MDS exist, based on morphology of the blood cells, after diagnosis the most important determination to make is of the patient’s risk level, based on the International Prognostic Scoring System–Revised (IPSS-R), updated in 2022.

While there are six MDS risk levels, patients generally fall into the high-risk and low-risk categories. The risk-level workup includes “a bone marrow biopsy with morphology, looking at how many blasts they have, looking for dysplasia, cytogenetics, and a full spectrum myeloid mutation testing, or molecular testing,” according to Anna Halpern, MD, an assistant professor of hematology in the clinical research division at Fred Hutchinson Cancer Center, Seattle. ”I use that information and along with their age, in some cases to calculate an IPSS-M or IPPS-R score, and what goes into that risk stratification includes how low their blood counts are as well as any adverse risks features we might see in their marrow, like adverse risk genetics, adverse risk mutations or increased blasts.”

Treatment decisions then turn on whether a patient is high risk – about a third of MDS patients – or low risk, because those treatment goals differ.

“With low-risk, the goal is to improve quality of life,” Dr. Raza said. “For higher-risk MDS, the goal is to prolong survival and delay progression to acute leukemia” since nearly a third of MDS patients will eventually develop AML.

More specifically, the aim with low-risk MDS is “to foster transfusion independence, either to prevent transfusions or to decrease the need for transfusions in people already receiving them,” explained Ellen Ritchie, MD, an assistant professor of medicine and hematologist-oncologist at Weill Cornell Medicine, New York. “We’re not hoping so much to cure the myelofibrosis at that point, but rather to improve blood counts.”

Sometimes, Dr. Halpern said, such treatment means active surveillance monitoring of blood counts, and at other times, it means treating cytopenia – most often anemia. The erythropoiesis-stimulating agents used to treat anemia are epoetin alfa (Epogen/Procrit) or darbepoetin alfa (Aranesp).

Ms. Trueman, whose MDS is low risk, started taking Aranesp, but she didn’t feel well on the drug and didn’t think it was helping much. She was taken off that drug and now relies only on transfusions for treatment, when her blood counts fall too low.

A newer anemia medication, luspatercept (Reblozyl), was approved in 2020 but is reserved primarily for those who fail one of the other erythropoiesis-stimulating agents and have a subtype of MDS with ring sideroblasts. Although white blood cell and platelet growth factors exist for other cytopenias, they’re rarely used because they offer little survival benefit and carry risks, Dr. Halpern said. The only other medication typically used for low-risk MDS is lenalidomide (Revlimid), which is reserved only for those with 5q-deletion syndrome.

The goal of treating high-risk MDS, on the other hand, is to cure it – when possible.

“The only curative approach for MDS is an allogeneic stem cell transplant or bone marrow transplant,” Dr. Halpern said, but transplants carry high rates of morbidity and mortality and therefore require a base level of physical fitness for a patient to consider it.

Dr. Koprivnikar observed that “MDS is certainly a disease of the elderly, and with each increasing decade of life, incidence increases. So there are a lot of patients who do not qualify for transplant.”

Age is not the sole determining factor, however. Dr. Ritchie noted that transplants can be offered to patients up to age 75 and sometimes older, depending on their physical condition. “It all depends upon the patient, their fitness, how much caretaker support they have, and what their comorbid illnesses are.”

If a transplant isn’t an option, Dr. Halpern and Dr. Raza said, they steer patients toward clinical trial participation. Otherwise, the first-line treatment is chemotherapy with hypomethylating agents to hopefully put patients in remission, Dr. Ritchie said.

The main chemo agents for high-risk patients ineligible for transplant are azacitidine (Vidaza) or decitabine (Dacogen), offered indefinitely until patients stop responding or experience progression or intolerance, Dr. Koprivnikar said. The only recently approved drug in this space is Inqovi, which is not a new agent, but it provides decitabine and cedazuridine in an oral pill form, so that patients can avoid infusions.
 

Treatment gaps

Few treatments options currently exist for patients with MDS, beyond erythropoiesis-stimulating agents for low-risk MDS and chemotherapy or transplant for high-risk MDS, as well as lenalidomide and luspatercept for specific subpopulations. With few breakthroughs occurring, Dr. Halpern expects that progress will only happen gradually, with new treatments coming primarily in the form of AML therapies.

“The biggest gap in our MDS regimen is treatment that can successfully treat or alter the natural history of TP53-mutated disease,” said Dr. Halpern, referring to an adverse risk mutation that can occur spontaneously or as a result of exposure to chemotherapy or radiation. “TP53-mutated MDS is very challenging to treat, and we have not had any successful therapy, so that is the biggest area of need.”

The most promising possibility in that area is an anti-CD47 drug called magrolimab, a drug being tested in a trial of which Dr. Halpern is a principal investigator. Not yet approved, magrolimab has been showing promise for AML when given with azacitidine (Vidaza) and venetoclax (Venclexta).

Venetoclax, currently used for AML, is another drug that Dr. Halpern expects to be approved for MDS soon. A phase 1b trial presented at the 2021 annual meeting of the American Hematology Society found that more than three-quarters of patients with high-risk MDS responded to the combination of venetoclax and azacitidine.

Unlike so many other cancers, MDS has seen little success with immunotherapy, which tends to have too much toxicity for patients with MDS. While Dr. Halpern sees potential for more exploration in this realm, she doesn’t anticipate immunotherapy or chimeric antigen receptor T-cell therapy becoming treatments for MDS in the near future.

“What I do think is, hopefully, we will have better treatment for TP53-mutated disease,” she said, while adding that there are currently no standard options for patients who stopped responding or don’t respond to hypomethylating agents.

Similarly, few new treatments have emerged for low-risk MDS, but there a couple of possibilities on the horizon.

“For a while, low-risk, transfusion-dependent MDS was an area that was being overlooked, and we are starting to see more activity in that area as well, with more drugs being developed,” Dr. Koprivnikar said. Drugs showing promise include imetelstat – an investigative telomerase inhibitor – and IRAK inhibitors. A phase 3 trial of imetelstat recently met its primary endpoint of 8 weeks of transfusion independence in low-risk MDS patients who aren’t responding to or cannot take erythropoiesis-stimulating agents, like Ms. Trueman. If effective and approved, a drug like imetelstat may allow patients like Ms. Trueman to resume some activities that she misses now.

“I have so much energy in my head, and I want to do so much, but I can’t,” Ms. Trueman said. “Now I think I’m getting lazy and I don’t like it because I’m not that kind of person. It’s pretty hard.”

Dr. Raza disclosed relationships with Epizyme, Grail, Vor, Taiho, RareCells, and TFC Therapeutics. Dr Ritchie reported ties with Jazz Pharmaceuticals, Novartis, Takeda, Incyte, AbbVie, Astellas, and Imago Biosciences. Dr. Halpern disclosed relationships with AbbVie, Notable Labs, Imago, Bayer, Gilead, Jazz, Incyte, Karyopharm, and Disc Medicine.

Until just over a year ago, Pat Trueman, an 82-year-old in New Hampshire, had always been a “go-go-go” kind of person. Then she started feeling tired easily, even while doing basic housework.

“I had no stamina,” Ms. Trueman said. “I didn’t feel that bad, but I just couldn’t do anything.” She had also begun noticing black and blue bruises appearing on her body, so she met with her cardiologist. But when switching medications and getting a pacemaker didn’t rid Ms. Trueman of the symptoms, her doctor referred her to a hematologist oncologist.

A bone marrow biopsy eventually revealed that Ms. Trueman had myelodysplastic neoplasms, or MDS, a blood cancer affecting an estimated 60,000-170,000 people in the United States, mostly over age 60. MDS includes several bone marrow disorders in which the bone marrow does not produce enough healthy, normal blood cells. Cytopenias are therefore a key feature of MDS, whether it’s anemia (in Ms. Trueman’s case), neutropenia, or thrombocytopenia.

Jamie Koprivnikar, MD, a hematologist oncologist at Hackensack (N.J) University Medical Center, describes the condition to her patients using a factory metaphor: “Our bone marrow is the factory where the red blood cells, white blood cells, and platelets are made, and MDS is where the machinery of the factory is broken, so the factory is making defective parts and not enough parts.”

The paradox of MDS is that too many cells are in the bone marrow while too few are in the blood, since most in the marrow die before reaching the blood, explained Azra Raza, MD, a professor of medicine and director of the MDS Center at Columbia University Medical Center, New York, and author of The First Cell (New York: Basic Books, 2019).

Although MDS is not rare, the condition has seen remarkably few new therapies in recent years. Most are either improvements on an existing treatment – such as an oral formulation of an infused drug – or a drug borrowed from therapies for other blood cancers, particularly acute myeloid leukemia (AML).

“We’re looking at taking a lot of the therapies that we’ve used to treat AML and then trying to apply them to MDS,” Dr. Koprivnikar said. “With all the improvement that we’re seeing there with leukemia, we’re definitely expecting this trickle-down effect to also help our high-risk MDS patients.”
 

Workup begins with risk stratification

While different types of MDS exist, based on morphology of the blood cells, after diagnosis the most important determination to make is of the patient’s risk level, based on the International Prognostic Scoring System–Revised (IPSS-R), updated in 2022.

While there are six MDS risk levels, patients generally fall into the high-risk and low-risk categories. The risk-level workup includes “a bone marrow biopsy with morphology, looking at how many blasts they have, looking for dysplasia, cytogenetics, and a full spectrum myeloid mutation testing, or molecular testing,” according to Anna Halpern, MD, an assistant professor of hematology in the clinical research division at Fred Hutchinson Cancer Center, Seattle. ”I use that information and along with their age, in some cases to calculate an IPSS-M or IPPS-R score, and what goes into that risk stratification includes how low their blood counts are as well as any adverse risks features we might see in their marrow, like adverse risk genetics, adverse risk mutations or increased blasts.”

Treatment decisions then turn on whether a patient is high risk – about a third of MDS patients – or low risk, because those treatment goals differ.

“With low-risk, the goal is to improve quality of life,” Dr. Raza said. “For higher-risk MDS, the goal is to prolong survival and delay progression to acute leukemia” since nearly a third of MDS patients will eventually develop AML.

More specifically, the aim with low-risk MDS is “to foster transfusion independence, either to prevent transfusions or to decrease the need for transfusions in people already receiving them,” explained Ellen Ritchie, MD, an assistant professor of medicine and hematologist-oncologist at Weill Cornell Medicine, New York. “We’re not hoping so much to cure the myelofibrosis at that point, but rather to improve blood counts.”

Sometimes, Dr. Halpern said, such treatment means active surveillance monitoring of blood counts, and at other times, it means treating cytopenia – most often anemia. The erythropoiesis-stimulating agents used to treat anemia are epoetin alfa (Epogen/Procrit) or darbepoetin alfa (Aranesp).

Ms. Trueman, whose MDS is low risk, started taking Aranesp, but she didn’t feel well on the drug and didn’t think it was helping much. She was taken off that drug and now relies only on transfusions for treatment, when her blood counts fall too low.

A newer anemia medication, luspatercept (Reblozyl), was approved in 2020 but is reserved primarily for those who fail one of the other erythropoiesis-stimulating agents and have a subtype of MDS with ring sideroblasts. Although white blood cell and platelet growth factors exist for other cytopenias, they’re rarely used because they offer little survival benefit and carry risks, Dr. Halpern said. The only other medication typically used for low-risk MDS is lenalidomide (Revlimid), which is reserved only for those with 5q-deletion syndrome.

The goal of treating high-risk MDS, on the other hand, is to cure it – when possible.

“The only curative approach for MDS is an allogeneic stem cell transplant or bone marrow transplant,” Dr. Halpern said, but transplants carry high rates of morbidity and mortality and therefore require a base level of physical fitness for a patient to consider it.

Dr. Koprivnikar observed that “MDS is certainly a disease of the elderly, and with each increasing decade of life, incidence increases. So there are a lot of patients who do not qualify for transplant.”

Age is not the sole determining factor, however. Dr. Ritchie noted that transplants can be offered to patients up to age 75 and sometimes older, depending on their physical condition. “It all depends upon the patient, their fitness, how much caretaker support they have, and what their comorbid illnesses are.”

If a transplant isn’t an option, Dr. Halpern and Dr. Raza said, they steer patients toward clinical trial participation. Otherwise, the first-line treatment is chemotherapy with hypomethylating agents to hopefully put patients in remission, Dr. Ritchie said.

The main chemo agents for high-risk patients ineligible for transplant are azacitidine (Vidaza) or decitabine (Dacogen), offered indefinitely until patients stop responding or experience progression or intolerance, Dr. Koprivnikar said. The only recently approved drug in this space is Inqovi, which is not a new agent, but it provides decitabine and cedazuridine in an oral pill form, so that patients can avoid infusions.
 

Treatment gaps

Few treatments options currently exist for patients with MDS, beyond erythropoiesis-stimulating agents for low-risk MDS and chemotherapy or transplant for high-risk MDS, as well as lenalidomide and luspatercept for specific subpopulations. With few breakthroughs occurring, Dr. Halpern expects that progress will only happen gradually, with new treatments coming primarily in the form of AML therapies.

“The biggest gap in our MDS regimen is treatment that can successfully treat or alter the natural history of TP53-mutated disease,” said Dr. Halpern, referring to an adverse risk mutation that can occur spontaneously or as a result of exposure to chemotherapy or radiation. “TP53-mutated MDS is very challenging to treat, and we have not had any successful therapy, so that is the biggest area of need.”

The most promising possibility in that area is an anti-CD47 drug called magrolimab, a drug being tested in a trial of which Dr. Halpern is a principal investigator. Not yet approved, magrolimab has been showing promise for AML when given with azacitidine (Vidaza) and venetoclax (Venclexta).

Venetoclax, currently used for AML, is another drug that Dr. Halpern expects to be approved for MDS soon. A phase 1b trial presented at the 2021 annual meeting of the American Hematology Society found that more than three-quarters of patients with high-risk MDS responded to the combination of venetoclax and azacitidine.

Unlike so many other cancers, MDS has seen little success with immunotherapy, which tends to have too much toxicity for patients with MDS. While Dr. Halpern sees potential for more exploration in this realm, she doesn’t anticipate immunotherapy or chimeric antigen receptor T-cell therapy becoming treatments for MDS in the near future.

“What I do think is, hopefully, we will have better treatment for TP53-mutated disease,” she said, while adding that there are currently no standard options for patients who stopped responding or don’t respond to hypomethylating agents.

Similarly, few new treatments have emerged for low-risk MDS, but there a couple of possibilities on the horizon.

“For a while, low-risk, transfusion-dependent MDS was an area that was being overlooked, and we are starting to see more activity in that area as well, with more drugs being developed,” Dr. Koprivnikar said. Drugs showing promise include imetelstat – an investigative telomerase inhibitor – and IRAK inhibitors.

NEW ORLEANS – A monoclonal antibody targeting interferon-beta (IFN-beta) provided substantial reductions in the skin lesions associated with dermatomyositis in a double-blind, placebo-controlled phase 2 trial, according to results presented as a late-breaker at the annual meeting of the American Academy of Dermatology.

“These findings support the inhibition of IFN-beta as a promising therapeutic strategy in skin-predominant disease,” said principal investigator Aaron Mangold, MD, associate professor of dermatology, Mayo Clinic, Scottsdale, Ariz.

Ted Bosworth/MDedge News

Dermatomyositis, a rare autoimmune inflammatory condition that typically involves both skeletal muscles and skin, is a challenging disease with a diverse set of potential complications.

Immunosuppressive and immunomodulatory agents are used with mixed success for myositis, but skin manifestations, which include papular eruptions, heliotrope rash, photoerythema, burning, and pruritus, are often the most troublesome and the most difficult to control. Treatment options other than immunomodulators that target cutaneous involvement – which include steroids, emollients, and photoprotection – are generally modestly effective, according to Dr. Mangold.
 

Targeting an elevated cytokine

Interest in IFN-beta, which is elevated in the blood of individuals with dermatomyositis, was triggered by evidence that this cytokine plays an important role in driving the skin inflammation, Dr. Mangold explained.

“The blood concentrations of IFN-beta are positively correlated with cutaneous disease activity and severity,” he said.

The study drug, currently known as PF-06823859 (Dazukibart), “is a potent, selective humanized IgG1-neutralizing antibody directed at IFN-beta,” Dr. Mangold said. A dose-ranging phase 1 study published 2 years ago provided evidence of acceptable pharmacokinetics and safety in healthy individuals to support treatment studies for disorders associated with elevated IFN-beta levels. In addition to dermatomyositis, this includes systemic lupus erythematosus.

In this phase 2 trial, patients whose condition was not improved by at least one standard-care therapy for skin manifestations of dermatomyositis were eligible if they had moderate to severe disease as measured with the Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI), according to Dr. Mangold. During the study, patients were allowed to remain on a disease modifying antirheumatic drug and/or prednisone if they had been on stable doses and did not change the dose.

Richard Usatine, MD

After a screening run-in, the trial had two blinded stages. In stage 1, 30 patients were randomly assigned either to 600 mg of PF-06823859 or to placebo, both administered intravenously every 4 weeks. A second cohort of 25 patients was randomly assigned in stage 2 to placebo, 150 mg of PF-06823859, or 600 mg of PF-06823859. The primary endpoint assessed at 12 weeks was a greater than 5-point reduction in CDASI score or greater than 40% CDASI improvement from baseline.

Both endpoints are associated with a clinically meaningful response in regard to an improved quality of life, Dr. Mangold noted.
 

Both doses better than placebo

In results from the stage 1 portion, the mean reduction in CDASI at 12 weeks after three doses of the assigned therapy was 18.8 points in the active-treatment group versus 3.9 points in the placebo group. In pooled data from stage 1 and 2, the reductions were 16.6 points, 19.2 points, and 2.9 points for the 150-mg, 600-mg, and placebo arms, respectively. Both doses achieved a highly significant advantage over placebo.

For both stages and doses, the response curves of the active-treatment groups and the placebo group diverged almost immediately. By 4 weeks, both measures of CDASI reductions on active therapy were significantly improved relative to placebo, and the response curves had a consistent downward slope through the end of the 12-week study, Dr. Mangold reported.

The majority of patients responded by either of the primary endpoint criteria. For a CDASI reduction of greater than 5 points, the response rates were 100% and 96% for the 150-mg and 600-mg doses of PF-06823859, respectively. The placebo response was 35.7%. For the CDASI reduction of greater than 40%, the rates were 80%, 82.1%, and 7.1% for the 150-mg, 600-mg, and placebo arms, respectively.

“There were no major safety concerns. Most of the treatment-emergent adverse events were mild, and adverse events did not have a relationship to dose,” Dr. Mangold said. Notably, there were no cases of herpes zoster, and infections of any kind were low in all study groups.

A phase 3 study is being planned with the 600-mg dose, according to Dr. Mangold, but he acknowledged that regulatory authorities have generally required endpoints for both cutaneous and muscle manifestations in previous trials of therapies for dermatomyositis.

It is not yet certain that “there will be a carve-out for skin,” he said in answer to a question about investigations moving forward. So far, studies have been focused on skin response. However, a meaningful degree of benefit against muscle involvement, which has not yet been well studied, has not been ruled out.

Even though this is a phase 2 trial with small numbers, it was controlled and blinded, and the potential of an inhibitor of IFN-beta to control the skin manifestations of dermatomyositis “is kind of a big deal,” said Paul Nghiem, MD, PhD, professor of dermatology, University of Washington, Seattle.

“There is definitely an unmet need for better therapies to control the skin involvement,” Dr. Nghiem said.

Hensin Tsao, MD, PhD, clinical director of the Melanoma and Pigmented Lesion Center at Massachusetts General Hospital, Boston, agreed. Like Dr. Nghiem, Dr. Tsao was a panelist during the late-breaker session where the study was presented, and he was impressed by the data.

“This is something that is definitely newsworthy,” Dr. Tsao said.

Dr. Mangold reports financial relationships with Actelion, Amgen, Corbus, Eli Lilly, Incyte, miRagen, Novartis, Regeneron, Solagenix, Sun Pharmaceuticals, Teva, and Pfizer, which provided funding for this trial. Both Dr. Nghiem and Dr. Tsao reported no relevant financial relationships.

“These findings support the inhibition of IFN-beta as a promising therapeutic strategy in skin-predominant disease,” said principal investigator Aaron Mangold, MD, associate professor of dermatology, Mayo Clinic, Scottsdale, Ariz.

Dermatomyositis, a rare autoimmune inflammatory condition that typically involves both skeletal muscles and skin, is a challenging disease with a diverse set of potential complications.

Immunosuppressive and immunomodulatory agents are used with mixed success for myositis, but skin manifestations, which include papular eruptions, heliotrope rash, photoerythema, burning, and pruritus, are often the most troublesome and the most difficult to control. Treatment options other than immunomodulators that target cutaneous involvement – which include steroids, emollients, and photoprotection – are generally modestly effective, according to Dr. Mangold.
 

Targeting an elevated cytokine

Interest in IFN-beta, which is elevated in the blood of individuals with dermatomyositis, was triggered by evidence that this cytokine plays an important role in driving the skin inflammation, Dr. Mangold explained.

“The blood concentrations of IFN-beta are positively correlated with cutaneous disease activity and severity,” he said.

The study drug, currently known as PF-06823859 (Dazukibart), “is a potent, selective humanized IgG1-neutralizing antibody directed at IFN-beta,” Dr. Mangold said. A dose-ranging phase 1 study published 2 years ago provided evidence of acceptable pharmacokinetics and safety in healthy individuals to support treatment studies for disorders associated with elevated IFN-beta levels. In addition to dermatomyositis, this includes systemic lupus erythematosus.

In this phase 2 trial, patients whose condition was not improved by at least one standard-care therapy for skin manifestations of dermatomyositis were eligible if they had moderate to severe disease as measured with the Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI), according to Dr. Mangold. During the study, patients were allowed to remain on a disease modifying antirheumatic drug and/or prednisone if they had been on stable doses and did not change the dose.

After a screening run-in, the trial had two blinded stages. In stage 1, 30 patients were randomly assigned either to 600 mg of PF-06823859 or to placebo, both administered intravenously every 4 weeks. A second cohort of 25 patients was randomly assigned in stage 2 to placebo, 150 mg of PF-06823859, or 600 mg of PF-06823859. The primary endpoint assessed at 12 weeks was a greater than 5-point reduction in CDASI score or greater than 40% CDASI improvement from baseline.

Both endpoints are associated with a clinically meaningful response in regard to an improved quality of life, Dr. Mangold noted.
 

Both doses better than placebo

In results from the stage 1 portion, the mean reduction in CDASI at 12 weeks after three doses of the assigned therapy was 18.8 points in the active-treatment group versus 3.9 points in the placebo group. In pooled data from stage 1 and 2, the reductions were 16.6 points, 19.2 points, and 2.9 points for the 150-mg, 600-mg, and placebo arms, respectively. Both doses achieved a highly significant advantage over placebo.

For both stages and doses, the response curves of the active-treatment groups and the placebo group diverged almost immediately. By 4 weeks, both measures of CDASI reductions on active therapy were significantly improved relative to placebo, and the response curves had a consistent downward slope through the end of the 12-week study, Dr. Mangold reported.

The majority of patients responded by either of the primary endpoint criteria. For a CDASI reduction of greater than 5 points, the response rates were 100% and 96% for the 150-mg and 600-mg doses of PF-06823859, respectively. The placebo response was 35.7%. For the CDASI reduction of greater than 40%, the rates were 80%, 82.1%, and 7.1% for the 150-mg, 600-mg, and placebo arms, respectively.

“There were no major safety concerns. Most of the treatment-emergent adverse events were mild, and adverse events did not have a relationship to dose,” Dr. Mangold said. Notably, there were no cases of herpes zoster, and infections of any kind were low in all study groups.

A phase 3 study is being planned with the 600-mg dose, according to Dr. Mangold, but he acknowledged that regulatory authorities have generally required endpoints for both cutaneous and muscle manifestations in previous trials of therapies for dermatomyositis.

It is not yet certain that “there will be a carve-out for skin,” he said in answer to a question about investigations moving forward. So far, studies have been focused on skin response. However, a meaningful degree of benefit against muscle involvement, which has not yet been well studied, has not been ruled out.

Even though this is a phase 2 trial with small numbers, it was controlled and blinded, and the potential of an inhibitor of IFN-beta to control the skin manifestations of dermatomyositis “is kind of a big deal,” said Paul Nghiem, MD, PhD, professor of dermatology, University of Washington, Seattle.

“There is definitely an unmet need for better therapies to control the skin involvement,” Dr. Nghiem said.

Hensin Tsao, MD, PhD, clinical director of the Melanoma and Pigmented Lesion Center at Massachusetts General Hospital, Boston, agreed. Like Dr. Nghiem, Dr. Tsao was a panelist during the late-breaker session where the study was presented, and he was impressed by the data.

“This is something that is definitely newsworthy,” Dr. Tsao said.

Dr. Mangold reports financial relationships with Actelion, Amgen, Corbus, Eli Lilly, Incyte, miRagen, Novartis, Regeneron, Solagenix, Sun Pharmaceuticals, Teva, and Pfizer, which provided funding for this trial. Both Dr. Nghiem and Dr. Tsao reported no relevant financial relationships.

A tendency towards harm avoidance was a significant predictor of later depression, based on long-term data from nearly 4,000 individuals.

Temperament has been defined as “an individual’s propensity to react emotionally, learn behavior and to form attachments without conscious effort by associative conditioning,” wrote Aleksi Ahola, PhD, of the University of Oulu, Finland, and colleagues. “Temperament is a potential endophenotype for depression, as it is inheritable and genetically linked with depression,” they said. The Temperament and Character Inventory (TCI) includes four temperament traits: harm avoidance (HA), novelty seeking (NS), reward dependence (RD), and persistence (P); previous studies have shown associations between higher HA and depression, but long-term data are limited, they wrote.

In a population-based study published in Comprehensive Psychiatry, the researchers followed 3,999 adults from age 31 to 54 years. The participants were part of the Northern Finland Birth Cohort 1966 Study.

The primary outcome was the onset of depression in a previously mentally healthy adult population. Temperament was assessed using the TCI, and depression was based on the Hopkins system checklist-25 (SCL-25). Individuals with previous psychiatric disorders related to depression, bipolar disorder, or psychosis were excluded. Effect size was measured using the Cohen’s d test.

Overall, 240 individuals were diagnosed with depression over the follow-up period. Women later diagnosed with depression had higher baseline TCI scores for HA, compared with those without depression. After controlling for multiple variables, higher TCI scores for HA, NS, and P were significantly associated with increased risk of any depression.

Among men, the TCI HA score was associated with significantly increased risk of any depression after adjustments, but no association appeared for other TCI scores. However, higher RD was associated with a reduced risk of psychotic depression in men (odds ratio, 0.79), although the study was not designed to assess psychotic depression, the researchers noted.

In an additional analysis of temperament cluster groups, shy and pessimistic traits were associated with depression in men (OR, 1.89), but not in women. In women, the cluster group with no specific extreme personality traits (cluster III) appeared to show an association with depression, which may be related to the association of NS and P with depression, the researchers wrote in their discussion.

The study is the first known to show differences between genders in the prediction of depression based on temperament traits, notably the link between high persistence and the onset of any depression in women, they said.

The study findings were limited by several factors including the potential for missed cases of less severe depression not reported in a national register, and by the relatively small number of men in the study, the researchers noted. In addition, the TCI’s three character traits of self-directedness, cooperativeness, and self-transcendence were not part of the current study, they said.

However, the results were strengthened by the large sample size, premorbid temperament assessment, and long follow-up period, although more research is needed in larger populations using real-world personalities to confirm the findings, they said.

“Research regarding temperament is important as it may have clinical significance as predictor of psychiatric morbidity and even suicide risk,” they said.

“Understanding those potentially at risk of depression could help in preventing the onset of the disease, and creating cluster profiles to match real-world personas could offer a clinical tool for this kind of prevention,” they concluded.

The study was supported by the University of Oulu, Oulu University Hospital, the Ministry of Health and Social Affairs, the National Institute for Health and Welfare, and the Regional Institute of Occupational Health. The researchers had no financial conflicts to disclose.

Screening high-risk populations for lung cancer saves lives. The National Lung Screening Trial (NLST) demonstrated a 20% relative reduction in lung cancer mortality with annual screening over 3 years with low-dose CT as compared with x-rays. The NELSON trial found a higher benefit: Men at high risk for lung cancer had a 26% reduced risk of dying from lung cancer and women had a 61% reduced risk over 10 years. However, the 2022 American Lung Association State of Lung Cancer report shows that less than 6% of eligible people get screened. Why is this?

There are many reasons, but I submit that at least one hurdle is related to the difficulties associated with ordering the low-dose CT in the electronic medical record (EMR) and following the results. The rules and regulations around lung cancer screening are complex. First, the ordering provider must be able to determine if the patient is eligible for screening and has insurance coverage – a complicated procedure, which is constantly in flux, and is based on age, smoking history, smoke-free interval, and type of insurance coverage. Most EMRs do not have a way of flagging high-risk individuals, and clinic coordinators (for those practices that have one) are often put in charge of determining eligibility.

Secondly, the health care provider must order the scan. Unlike mammography, people must have a prescreening visit with a physician or other health care provider – a visit which is poorly compensated, and often must be supported by the institution. Many EMRs also do not have a smooth mechanism to make sure all the “boxes have been checked” before the scan can be ordered. Is there a complete smoking history? Has the patient had their prescreening visit? Has the patient been counseled regarding tobacco use? Has eligibility for insurance payment been confirmed?

Coordinating follow-up is cumbersome. Abnormal findings are common and usually nonmalignant, but must be followed up, and the follow-up recommendations are complicated and are based upon the appearance of the finding. This may be difficult for a general practitioner, so referrals to pulmonologists are often scheduled. Best practices state the patient be followed in a multidisciplinary pulmonary module clinic, but again, most multidisciplinary pulmonary module clinics are found in the academic setting.

All this involves a lot of back-and-forth for the patient: First to see their primary care physician, then to see a pulmonologist or other health care provider for the counseling regarding risks and benefits of screening and the importance of smoking cessation, and then a visit to a radiologist as well as a visit to a smoking cessation clinic, then a return follow-up visit. Academic medical centers and NCI-approved cancer centers often have these procedures worked out, but many private or smaller practices do not. Yes, the local IT folks can modify an EMR, but in a small practice, there are other “more important” problems that take precedence.

Would coupling lung cancer screening with breast cancer scanning help? One study followed 874 women who attended mammographic screening and found that over 11% were at high risk for lung cancer. This would appear to be an ideal “teaching moment” to educate the importance of lung cancer screening to women. It could also cut down on some of the logistical issues associated with lung cancer screening, particularly if a health care provider and coordinator were immediately available for counseling and eligibility determination at the time of the mammography visit. The radiology clinic staff could schedule a scan and return visit while the patient was still in the mammography suite.

Of course, the logistical hassle is just one of many associated with lung cancer screening. The internal stigma the patient may experience about their smoking history, the unconscious bias on the part of many health professionals, the many other screening and prevention regulations providers are now required to follow, the institution’s reluctance to support a screening program, the rushed pace in many clinics: These all certainly contribute to the problem. However, we have overcome all of these issues when it comes to mammography, such as work flow, stigma, logistical issues, seamless incorporation of ordering scans and referrals to specialists in the EMR, etc. We can and must do the same for our patients at high risk for lung cancer, and routine scheduling of mammograms and low-dose CTs may help.

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.

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.

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.
