New York City is closing 10 city-run sites where children younger than 5 could get the COVID-19 vaccine, with three of those sites transitioning to administer the monkeypox vaccine.

The city health department said demand for children’s COVID vaccines had been on the downswing at the clinics, which opened in late June. Meanwhile, monkeypox cases have increased, with the city declaring it a public health emergency July 30.

“We always planned to transition vaccination for very young children to providers,” the city’s health department said in a statement, according to Spectrum News NY1. “Due to the ongoing monkeypox emergency, we transitioned some of these sites to administer monkeypox vaccine.”

All the COVID vaccine sites for children will close by Aug. 14, Spectrum News NY1 said. It’s unclear if the other sites will transition to monkeypox vaccine.

No appointments for children’s COVID vaccinations had to be canceled, the city said. The plan is that children now needing the COVID vaccine can go to doctors, pharmacies, or the health department clinics.

Manhattan City Councilwoman Gale Brewer urged the health department to keep the kids’ COVID vaccine sites open through the fall.

“I strongly urge you to maintain these family-friendly sites, at least until mid-September so that children who are going to day care and school can get vaccinated,” Brewer wrote. City schools open Sept. 8

Ms. Brewer noted that the city-run sites administered the Moderna vaccines, while many doctors and neighborhood health clinics use the Pfizer vaccine. That could be a problem for a child that had not finished the Moderna regimen or for families that prefer Moderna.

According to the city health department, 2,130 people in New York City had tested positive for monkeypox as of Aug. 12.

On Friday, the city announced 9,000 additional monkeypox vaccines would be made available the morning of Aug. 13.

The battle was just beginning for Le Roy Torres and his wife, Rosie, when the Army captain returned to Texas in 2008, already starting to suffer from the toxic substances he’d inhaled from the 10-acre burn pit at Camp Anaconda in Balad, Iraq.

Along the way, Le Roy would lose the job he loved as a Texas state trooper and take his fight all the way to a Supreme Court victory. He would be rushed to the emergency room hundreds of times, be denied health benefits by the Department of Veterans Affairs for years, attempt suicide, and seek experimental cures for the damage done to his lungs and brain.

Amid all that, Le Roy and Rosie founded an organization to help others and push Congress to fix the laws that allowed the suffering of veterans to go on, and ultimately enlist people like comedian and activist Jon Stewart, who helped them win a dramatic showdown in the Senate last week.

Their struggle will never really be over. But the Torreses’ campaign to make sure no other veterans experience what they had to ends Aug. 10, when they are set to join President Joe Biden as he signs a law to guarantee that 3.5 million American warriors exposed to similar hazards can get care.

“I mean, to think that 13 years ago we were walking the halls [of Congress] — it’s really emotional,” Rosie said recently, halting to collect herself and wipe back tears, “because I think of all the people that died along the way.”

The bill provides a new entitlement program for veterans who served in a combat zone in the past 32 years. If they are diagnosed with any of 23 conditions identified in the legislation — ranging from specific cancers to breathing ailments — they would be deemed automatically eligible for health coverage. The Congressional Budget Office estimated the new benefits would cost $280 billion over the next 10 years.

Most veterans — nearly 80% — who start experiencing symptoms after leaving the service get denied what’s known as a service connection when they seek help from the VA. The system has been designed to disbelieve them, the veterans complain. They must prove their breathing problems or cancers came from the toxic trash smoke they breathed overseas, which is extremely difficult.

When Le Roy returned home from Balad Air Base — the second-largest U.S. post in Iraq and where the military incinerated tons of debris daily, including plastic, ammunition, and medical waste — he was already sick. He was rushed to the hospital a few weeks later with a severe respiratory infection.

He had expected to keep working as a state trooper, but by 2010 it was clear he couldn’t perform all the duties because of his illness. When he asked for a different job with the Texas Department of Public Safety, he was denied. He was told he had to resign if he wanted to apply for medical retirement. The retirement request was then rejected. So he sued and eventually took the case to the Supreme Court, which in June ruled that states were not immune from such lawsuits by service members.

In those early years, the military and VA doctors couldn’t say what caused his breathing problems and splitting headaches. As with other victims of toxic exposure, diagnoses proved to be difficult. Some doctors suggested the problems weren’t real — a pronouncement often encountered by other vets whose claims are denied.

Like so many others, Rosie turned to the internet for information she couldn’t get from the VA, where she had worked for 23 years. She discovered a Facebook group that she would use as the basis for a new advocacy group, Burn Pits 360.

Le Roy was ultimately diagnosed with constrictive bronchiolitis, fibrosis of the lungs, and toxic encephalopathy. He eventually got his benefits in early 2013. By then, the family was deep in debt.

For years he lived with the reality that the military he had served for 23 years refused to answer his needs, and the police force he loved didn’t seem to care.

“It’s something that we have now learned is known as moral injury and compound loss,” Rosie said.

As a man, he began to wonder how he could provide for his family, if he was any use to anyone, she added. “So then that led to him attempting to take his life.”

It also led the couple and parents of three to beseech Congress to fix the problems. They started walking the halls in the Capitol. Success there was not any easier.

“We came to Capitol Hill and just handed out information we had printed about burn pit exposure,” Le Roy said at his last visit to the Hill in June, an oxygen tube strung under his nose.

“There were a lot of doors shut in our face,” Rosie said.

While making little progress in Congress, they built Burn Pits 360 into an advocacy group and a clearinghouse to help other veterans similarly frustrated by a system that seemed to be failing them.

The breakthrough for Rosie began when she saw Stewart and 9/11 survivors’ advocate John Feal winning a similar battle to make Congress fully fund health and compensation programs for responders of the Sept. 11, 2001, terror attacks. She recalls reading up on the toxic substances in the dust and smoke that spewed from the collapsed twin towers and discovering they were remarkably similar to the poisons inhaled by troops near the waste fires that were also set ablaze with jet fuel.

She called Feal. Feal called Stewart, and by February 2019 the four of them were meeting on Capitol Hill with lawmakers, including Sen. Kirsten Gillibrand (D-N.Y.), one of the authors of the 9/11 legislation.

The key, they decided in those first meetings, was to remove the obstacles for the most common illnesses and eliminate the burden of proof on ill former soldiers. Gillibrand’s office wrote that bill, along with Rep. Raul Ruiz (D-Calif.), who championed it in the House.

Ultimately, that bill became the heart of the measure that passed, known as the PACT Act and named for a soldier who died from cancer linked to his service.

“Our bill was the first federal presumption for burn pits coverage ever. And that was all because of Rosie and Le Roy,” said Gillibrand.

But just as with the 9/11 legislation, many in Congress weren’t that interested.

“It’s about money, and nobody likes to spend money,” Gillibrand said. “Congress never wants to accept the fact that treating these veterans and addressing their health care is the cost of war.”

Weeks ago, the bill appeared ready to glide through. It passed both the House and Senate but needed another vote to fix a technical legislative issue. Then on July 27, Sen. Pat Toomey (R-Pa.), who opposed the measure, unexpectedly persuaded 25 of his Republican colleagues who had supported the bill to vote against it, claiming that because the bill made the spending mandatory — not subject to the annual whims of Congress — Democrats would spend $400 billion elsewhere in the budget. Democrats countered that the money Toomey cited is already being spent and, regardless of how it’s categorized, it’s still up to Congress to appropriate it.

Rosie and veterans who had come to the Capitol that day to celebrate instead had to dig in one more time, with Stewart bringing the high-wattage attention that led the Republicans to reconsider. On Aug. 2, most Republicans decided to agree with the Democrats, and the bill passed 86 to 11.

Rosie said it never would have happened without Feal and Stewart. Stewart said it was all about Rosie, bringing together veterans in a way that Congress couldn’t ignore.

“She’s the reason I’m doing it, her and Le Roy,” Stewart said, standing outside the Capitol with Rosie the day before the vote.

Stewart, the Torreses, and untold other veterans tempered their joy with the warning that it will be a hard journey making the new program work with a VA that already has a massive backlog. The legislation has provisions to create facilities and bring in private doctors, but some vets remain dubious.

Iraq War veteran Brian Alvarado of Long Beach, California, was diagnosed with neck and throat cancer soon after returning from Iraq in 2006. He had been assigned to patrol one of the many burn pits. He eats and breathes through tubes and struggles to keep weight on. Radiation and a tracheostomy have left his voice almost inaudible.

“You can pass laws, but it all boils down to the VA. How are they going to implement the changes? The claims, the compensation, the treatment,” he asked in June. “And how long will it take?”

For the time being, though, Rosie said that even more than a visit to the White House, she was looking forward to going back to Texas and her family.

“You know, I lost 13 years away from my children, with trips to the hospital, coming to D.C.,” she said. “It means I can go home.”

Le Roy and Rosie can also reflect that as painful as this path has been, 3.5 million veterans are guaranteed a backstop because of this law, and thousands of veterans and active-duty service members who work for state and local governments now have recourse if they are fired after being injured at war.

“It is good to know that so many people will be helped,” Le Roy said from his home in Robstown, Texas. “It does help.”

Cardiorespiratory fitness emerged as a stronger predictor of all-cause mortality than did any traditional risk factor across the spectrum of age, sex, and race in a modeling study that included more than 750,000 U.S. veterans.

In addition, mortality risk was cut in half if individuals achieved a moderate cardiorespiratory fitness (CRF) level – that is, by meeting the current U.S. physical activity recommendations of 150 minutes per week, the authors note.

Furthermore, contrary to some previous research, “extremely high” fitness was not associated with an increased risk for mortality in the study, published online in the Journal of the American College of Cardiology.

“This study has been 15 years in the making,” lead author Peter Kokkinos, PhD, Rutgers University, New Brunswick, N.J., and the VA Medical Center, Washington, told this news organization. “We waited until we had the computer power and the right people to really assess this. We wanted to be very liberal in excluding patients we thought might contaminate the results, such as those with cardiovascular disease in the 6 months prior to a stress test.”

Figuring the time was right, the team analyzed data from the VA’s Exercise Testing and Health Outcomes Study (ETHOS) on individuals aged 30-95 years who underwent exercise treadmill tests between 1999 and 2020.

After exclusions, 750,302 individuals (from among 822,995) were included: 6.5% were women; 73.7% were White individuals; 19% were African American individuals; 4.7% were Hispanic individuals; and 2.1% were Native American, Asian, or Hawaiian individuals. Septuagenarians made up 14.7% of the cohort, and octogenarians made up 3.6%.

CRF categories for age and sex were determined by the peak metabolic equivalent of task (MET) achieved during the treadmill test. One MET is the energy spent at rest – that is the basal metabolic rate.

Although some physicians may resist putting patients through a stress test, “the amount of information we get from it is incredible,” Dr. Kokkinos noted. “We get blood pressure, we get heart rate, we get a response if you’re not doing exercise. This tells us a lot more than having you sit around so we can measure resting heart rate and blood pressure.”

Lowest mortality at 14.0 METs

During a median follow-up of 10.2 years (7,803,861 person-years), 23% of participants died, for an average of 22.4 events per 1,000 person-years.

Higher exercise capacity was inversely related to mortality risk across the cohort and within each age category. Specifically, every 1 MET increase in exercise capacity yielded an adjusted hazard ratio for mortality of 0.86 (95% confidence interval, 0.85-0.87; P < .001) for the entire cohort and similar HRs by sex and race.

The mortality risk for the least-fit individuals (20th percentile) was fourfold higher than for extremely fit individuals (HR, 4.09; 95% CI, 3.90-4.20), with the lowest mortality risk at about 14.0 METs for both men (HR, 0.24; 95% CI, 0.23-0.25) and women (HR, 0.23; 95% CI, 0.17-0.29). Extremely high CRF did not increase the risk.

In addition, at 20 years of follow-up, about 80% of men and 95% of women in the highest CRF category (98th percentile) were alive vs. less than 40% of men and approximately 75% of women in the least fit CRF category.

“We know CRF declines by 1% per year after age 30,” Dr. Kokkinos said. “But the age-related decline is cut in half if you are fit, meaning that an expected 10% decline over a decade will be only a 5% decline if you stay active. We cannot stop or reverse the decline, but we can kind of put the brakes on, and that’s a reason for clinicians to continue to encourage fitness.” 

Indeed, “improving CRF should be considered a target in CVD prevention, similar to improving lipids, blood sugar, blood pressure, and weight,” Carl J. Lavie, MD, Ochsner Health, New Orleans, and colleagues affirm in a related editorial.
 

‘A difficult battle’

But that may not happen any time soon. “Unfortunately, despite having been recognized in an American Heart Association scientific statement as a clinical vital sign, aerobic fitness is undervalued and underutilized,” Claudio Gil Araújo, MD, PhD, research director of the Exercise Medicine Clinic-CLINIMEX, Rio de Janeiro, told this news organization.

Dr. Araújo led a recent study showing that the ability to stand on one leg for at least 10 seconds is strongly linked to the risk for death over the next 7 years.

Although physicians should be encouraging fitness, he said that “a substantial part of health professionals are physically unfit and feel uncomfortable talking about and prescribing exercise for their patients. Also, physicians tend to be better trained in treating diseases (using medications and/or prescribing procedures) than in preventing diseases by stimulating adoption of healthy habits. So, this a long road and a difficult battle.”

Nonetheless, he added, “Darwin said a long time ago that only the fittest will survive. If Darwin could read this study, he would surely smile.”

No commercial funding or conflicts of interest related to the study were reported. Dr. Lavie previously served as a speaker and consultant for PAI Health on their PAI (Personalized Activity Intelligence) applications.

Cardiorespiratory fitness emerged as a stronger predictor of all-cause mortality than did any traditional risk factor across the spectrum of age, sex, and race in a modeling study that included more than 750,000 U.S. veterans.

In addition, mortality risk was cut in half if individuals achieved a moderate cardiorespiratory fitness (CRF) level – that is, by meeting the current U.S. physical activity recommendations of 150 minutes per week, the authors note.

Furthermore, contrary to some previous research, “extremely high” fitness was not associated with an increased risk for mortality in the study, published online in the Journal of the American College of Cardiology.

Nebulized tobramycin significantly reduced the density of Pseudomonas aeruginosa in sputum and improved quality of life for adults with bronchiectasis in a study with more than 300 individuals.

Chronic P. aeruginosa infection remains a challenge for bronchiectasis patients, and treatment options are limited, wrote Wei-jie Guan, MD, of the First Affiliated Hospital of Guangzhou Medical University, Guangdong, China, and colleagues. Tobramycin has demonstrated antipseudomonal effects, but previous studies have been small, results have been inconclusive, and there are safety concerns with the currently approved method of intravenous injection.

In a study published in the journal Chest, the researchers randomly assigned 167 patients to receive nebulized tobramycin inhalation solution (TIS) and 172 patients to receive placebo. Patients in the active-treatment group received 300 mg/5 mL of TIS twice daily in two cycles of 28 days on- and off-treatment alternating periods. The primary endpoints were changes in P. aeruginosa density from baseline and scores on the Quality of Life–Bronchiectasis questionnaire at day 29. Follow-up data were collected every 4 weeks for 16 weeks. Secondary endpoints included rate of negative P. aeruginosa culture at day 29; change in P. aeruginosa density from baseline; quality of life at day 85; and 24-hour sputum volume and purulence at day 29, 57, and 85.

The study population included adults aged 18-75 years with symptomatic bronchiectasis. The participants’ conditions had been clinically stable for 4 weeks. Sputum cultures tested positive for P. aeruginosa at two consecutive screening visits prior to randomization. The study was conducted at 33 sites within mainland China.

Overall, among the patients in the TIS group, there was a significantly greater reduction in P. aeruginosa density, compared with placebo patients, with an adjusted mean difference of 1.74 Log10 colony-forming units/g (P < .001). TIS patients also showed significantly greater improvement in Quality of Life–Bronchiectasis respiratory symptom scores, with an adjusted mean difference of 7.91 (P < .001) at day 29.

In addition, more TIS patients became culture negative for P. aeruginosa by day 29, compared with placebo patients (29.3% vs. 10.6%), and 24-hour sputum volume and sputum purulence scores were significantly lower for TIS patients at day 29, day 57, and day 85, compared with placebo patients.

Adverse events were similar and occurred in 81.5% of TIS patients and 81.6% of placebo patients. The most common were hemoptysis, chest discomfort, and acute upper respiratory tract infections. A total of 10 patients in the TIS group experienced transient wheezing that resolved within 30 minutes. A total of 11 TIS patients and 5 placebo patients experienced an adverse event that caused them to discontinue participation in the study. These events included blurred vision and dizziness, which occurred in two TIS patients and was deemed related to the study drug. One TIS patient died as a result of acute myocardial infarction, but this was deemed to be unrelated to the study drug.

The findings were limited by several factors, including the short duration of treatment and relatively young population, which might affect generalizability, the researchers noted. Other limitations include a lack of data on the effects of TIS on microorganisms other than P. aeruginosa, as well as limited outpatient visits, owing to COVID-19 restrictions.

However, the results confirm the ability of TIS nebulization to reduce P. aeruginosa and improve quality of life for adult patients with bronchiectasis, the authors concluded.

The study was funded by grants to multiple researchers from the National Science and Technology Major Project of the Ministry of Science and Technology of China and other government sources. The researchers disclosed no relevant financial relationships.

Longitudinal progression of parenchymal changes on CT images — also referred to as quantitative interstitial abnormalities (QIA) – is independently associated with decreased lung function and an increased all-cause mortality risk, an analysis of two cohorts of ever-smokers indicates. And among the main risk factors for QIA progression is smoking.

“These abnormalities have gone by a few different names but fundamentally, they are high density findings of chest CT that in some cases represent early or subtle evidence of pulmonary fibrosis,” Samuel Ash, MD, MPH, assistant professor of medicine, Brigham and Women’s Hospital, Boston, told this news organization.

“I think this just adds to the huge list of reasons why people should quit smoking. So when I see someone with visual evidence of this type of change on their chest CT, I make sure to emphasize that while they don’t have interstitial lung disease [ILD] yet, these findings suggest they may be susceptible to lung injury from tobacco smoke and that if they don’t stop smoking now, they are at risk for a disease like interstitial pulmonary fibrosis [IPF] which is a highly morbid disease with a high mortality risk,” he added.

The study was published online in the journal CHEST.
 

Ever-smoking cohorts

Analysis of QIA progression on CT chest scans was carried out on participants from the Genetic Epidemiology of COPD (COPDGene) study as well as those from the Pittsburgh Lung Screening Study (PLuSS). COPDGene was a prospective cohort of over 10,300 ever-smokers with at least a 10–pack-year smoking history between the ages of 45 and 80. Participants underwent a series of tests including chest CT scans at baseline between 2006 and 2011 and again approximately 5 years later.

Patients with a postbronchodilator forced expiratory volume in 1 second (FEV₁) of 80% or more of predicted and a FEV₁-to-FVC (forced vital capacity) ratio of at least 0.7 were defined to have GOLD stage 0 disease while those with a postbronchodilator FEV₁ of 80% or less than predicted and a FEV₁-to-FVC ratio of at least 0.7 were defined to have preserved ratio impaired spirometry (PRISm) disease.

PLuSS involved 3,642 ever-smokers between the ages of 50 years and 79 years with at least a 12.5–pack-year history with no prior history of lung cancer. Participants again underwent a series of tests including a CT scan on visit 1 between 2002 and 2005 and then a second CT scan at a second visit almost 9 years later. “In the COPDGene cohort, 4,635 participants had complete clinical data, CT scans and spirometry from visits 1 and 2 for analysis,” the authors reported.

At visit 1 almost 48% of participants were current smokers and the mean pack-year history of the cohort was 41.9 years. The mean time between visits 1 and 2 was 5.6 years. Both the mean prebronchodilator FEV₁ as well as the mean FVC decreased between visits 1 and 2. For example, the mean prebronchodilator FEV₁ dropped from 2.2 liters to 2.0 liters between visits 1 and 2 while the mean prebronchodilator FVC decreased from 3.2 liters to 3.0 liters between the first and second visits.

In the PLuSS cohort, 1,307 participants had complete imaging and spirometry data available for visits 1 and 2 for analysis. The mean time between visits 1 and 2 was 8.6 years. Over 59% of the cohort were current smokers with a mean pack-year history of 65. Again, the mean prebronchodilator FEV1 and FVC both dropped between visit 1 and 2, as the authors note.

The mean prebronchodilator FEV1, for example, decreased from 2.5 liters to 2.1 liters between visits 1 and 2 while the mean prebronchodilator FVC dropped from 3.6 liters to 3.2 liters during the same interval. Looking at risk factors associated with QIA progression, investigators note that each additional year of baseline age was associated with a higher annual increase in QIA by 0.01% per year (95% confidence interval, 0.01%-0.02%; P < .001) in the COPDGene cohort and a 0.02% increase (95% CI, 0.01%-0.02%; P < .001) in the PLuSS cohort.

Female sex in turn was associated with a 0.07% per year (95% CI, 0.02%-0.12%; P = .003) higher increase in the QIA, compared with men in the COPDGene cohort and a 0.14% (95% CI, 0.02%-0.26%; P = .025) per year higher increase in the QIA in the PLuSS cohort. Current smoking status was only associated with a higher rate of QIA progression in the COPDGene cohort at a rate of 0.10% per year (95% CI, 0.06%-0.15%; P < .001).

Lastly, every copy of the minor allele of the MUIC5B promoter polymorphism was associated with a 0.12% per year (95% CI, 0.07%-0.16%; P < .0001) increase in QIA in the COPDGene cohort as well.
 

Smoking cessation

Smoking cessation is the obvious first step for patients with evidence of QIA progression but physicians can probably do more for these patients sooner, Dr. Ash said. “If we use heart disease as an analogy, we don’t want to start treating someone until they have a heart attack or are in heart failure, we start by checking their cholesterol and blood pressure and treating them with medications to prevent progression.”

Similarly, physicians need to start thinking about IPF and other lung diseases in the same way. For IPF, medications such as pirfenidone (Esbriet) and nintedanib (Ofev) do not reverse prior lung damage but they do slow disease progression and physicians need to initiate treatment before patients are short of breath, not after. Meantime, Dr. Ash advised physicians that, if they have a patient who is getting a CT scan for whatever reason, they should keep a close eye on whether or not patients have any of these interstitial changes and, if they do, then if the changes are getting worse.

“These patients are likely to be the ones who are going to develop IPF and who may benefit from ongoing imaging surveillance,” he said. And while clinicians may not yet be ready to use a quantitative tool at the bedside, “this tool – or one like it – is coming and we have to start thinking about how to incorporate these types of devices into our clinical practice.”
 

Temporal changes

Asked to comment on the findings, Surya Bhatt, MD, associate professor of medicine at the University of Alabama at Birmingham, said that the study advances the community’s understanding of the relationship between temporal changes in objectively measured interstitial lung abnormalities and several important clinical outcomes, including lung function decline and mortality. “Several risk factors for progression were also identified,” he noted.

“And these results make a case for initiating clinical trials to determine whether early treatment with existing antifibrotic medications in these high risk individuals can decrease the perpetuation of these permanent lung changes,” Dr. Bhatt said.

The COPDGene study was supported in part by contributions made by an industry advisory board. Dr. Ash was supported in part by Quantitative Imaging Solutions. Dr. Bhatt declared that he has receiving consulting fees or has service on advisory boards for Boehringer Ingelheim and Sanofi/Regeneron. He ha also received fee for CME from IntegrityCE.

Longitudinal progression of parenchymal changes on CT images — also referred to as quantitative interstitial abnormalities (QIA) – is independently associated with decreased lung function and an increased all-cause mortality risk, an analysis of two cohorts of ever-smokers indicates. And among the main risk factors for QIA progression is smoking.

“These abnormalities have gone by a few different names but fundamentally, they are high density findings of chest CT that in some cases represent early or subtle evidence of pulmonary fibrosis,” Samuel Ash, MD, MPH, assistant professor of medicine, Brigham and Women’s Hospital, Boston, told this news organization.

“I think this just adds to the huge list of reasons why people should quit smoking. So when I see someone with visual evidence of this type of change on their chest CT, I make sure to emphasize that while they don’t have interstitial lung disease [ILD] yet, these findings suggest they may be susceptible to lung injury from tobacco smoke and that if they don’t stop smoking now, they are at risk for a disease like interstitial pulmonary fibrosis [IPF] which is a highly morbid disease with a high mortality risk,” he added.

The study was published online in the journal CHEST.
 

Ever-smoking cohorts

Analysis of QIA progression on CT chest scans was carried out on participants from the Genetic Epidemiology of COPD (COPDGene) study as well as those from the Pittsburgh Lung Screening Study (PLuSS). COPDGene was a prospective cohort of over 10,300 ever-smokers with at least a 10–pack-year smoking history between the ages of 45 and 80. Participants underwent a series of tests including chest CT scans at baseline between 2006 and 2011 and again approximately 5 years later.

Patients with a postbronchodilator forced expiratory volume in 1 second (FEV₁) of 80% or more of predicted and a FEV₁-to-FVC (forced vital capacity) ratio of at least 0.7 were defined to have GOLD stage 0 disease while those with a postbronchodilator FEV₁ of 80% or less than predicted and a FEV₁-to-FVC ratio of at least 0.7 were defined to have preserved ratio impaired spirometry (PRISm) disease.

PLuSS involved 3,642 ever-smokers between the ages of 50 years and 79 years with at least a 12.5–pack-year history with no prior history of lung cancer. Participants again underwent a series of tests including a CT scan on visit 1 between 2002 and 2005 and then a second CT scan at a second visit almost 9 years later. “In the COPDGene cohort, 4,635 participants had complete clinical data, CT scans and spirometry from visits 1 and 2 for analysis,” the authors reported.

At visit 1 almost 48% of participants were current smokers and the mean pack-year history of the cohort was 41.9 years. The mean time between visits 1 and 2 was 5.6 years. Both the mean prebronchodilator FEV₁ as well as the mean FVC decreased between visits 1 and 2. For example, the mean prebronchodilator FEV₁ dropped from 2.2 liters to 2.0 liters between visits 1 and 2 while the mean prebronchodilator FVC decreased from 3.2 liters to 3.0 liters between the first and second visits.

In the PLuSS cohort, 1,307 participants had complete imaging and spirometry data available for visits 1 and 2 for analysis. The mean time between visits 1 and 2 was 8.6 years. Over 59% of the cohort were current smokers with a mean pack-year history of 65. Again, the mean prebronchodilator FEV1 and FVC both dropped between visit 1 and 2, as the authors note.

The mean prebronchodilator FEV1, for example, decreased from 2.5 liters to 2.1 liters between visits 1 and 2 while the mean prebronchodilator FVC dropped from 3.6 liters to 3.2 liters during the same interval. Looking at risk factors associated with QIA progression, investigators note that each additional year of baseline age was associated with a higher annual increase in QIA by 0.01% per year (95% confidence interval, 0.01%-0.02%; P < .001) in the COPDGene cohort and a 0.02% increase (95% CI, 0.01%-0.02%; P < .001) in the PLuSS cohort.

Female sex in turn was associated with a 0.07% per year (95% CI, 0.02%-0.12%; P = .003) higher increase in the QIA, compared with men in the COPDGene cohort and a 0.14% (95% CI, 0.02%-0.26%; P = .025) per year higher increase in the QIA in the PLuSS cohort. Current smoking status was only associated with a higher rate of QIA progression in the COPDGene cohort at a rate of 0.10% per year (95% CI, 0.06%-0.15%; P < .001).

Lastly, every copy of the minor allele of the MUIC5B promoter polymorphism was associated with a 0.12% per year (95% CI, 0.07%-0.16%; P < .0001) increase in QIA in the COPDGene cohort as well.
 

Smoking cessation

Smoking cessation is the obvious first step for patients with evidence of QIA progression but physicians can probably do more for these patients sooner, Dr. Ash said. “If we use heart disease as an analogy, we don’t want to start treating someone until they have a heart attack or are in heart failure, we start by checking their cholesterol and blood pressure and treating them with medications to prevent progression.”

Similarly, physicians need to start thinking about IPF and other lung diseases in the same way. For IPF, medications such as pirfenidone (Esbriet) and nintedanib (Ofev) do not reverse prior lung damage but they do slow disease progression and physicians need to initiate treatment before patients are short of breath, not after.

In 2021, in U.S. states far removed from one another, numerous cases of melioidosis (Whitmore’s disease) sprang up, some with a fatal outcome. What is the common factor linking all of those affected? So begins the search for evidence.

No relations or common journeys

Between March and July 2021, cases of the bacterial infectious disease sprang up in Georgia, Kansas, Minnesota, and Texas, with the disease being fatal for two of those affected. Usually, cases of melioidosis occur in the United States after traveling to regions where the pathogen is prevalent. However, none of the patients had undertaken any previous international travel.

When the genomes of the bacterial strains (Burkholderia pseudomallei) were sequenced, they showed a high level of concordance, suggesting a common source of infection. The bacterial strain is similar to those that are found in Southeast Asia above all. An imported product from there was taken into consideration as the trigger.

The Centers for Disease Control and Prevention examined blood samples from the patients, as well as samples from the soil, water, food, and household items around their homes.
 

Aroma spray as a trigger

In October, the cause of the melioidosis was finally identified in the house of the patient from Georgia: an aromatherapy spray. The genetic fingerprint of the bacterial strain matched with that from the other patients. The common trigger was thus discovered.

The contaminated spray, with a lavender-chamomile scent for room fragrancing, was sold between February and October in some branches of Walmart, as well as in their online store. The product was therefore recalled and it was checked whether the ingredients were also being used in other products.

The CDC requested physicians to also take melioidosis into account if they were presented with acute bacterial infections that did not respond to normal antibiotics and to inquire whether the affected room spray had been used.
 

More information about melioidosis

Melioidosis is an infectious disease affecting humans and animals. The trigger is the bacteria B pseudomallei. The disease appears predominantly in tropical regions, especially in Southeast Asia and northern Australia.

Transmission

The bacteria can be found in contaminated water and soil. It is disseminated between humans and animals through direct contact with the infectious source, such as through inhaling dust particles or water droplets, or through consuming contaminated water or food. Human-to-human transmission is extremely rare. Recently however, tropical saltwater fish were identified as potential carriers.

Symptoms

Melioidosis has a wide range of symptoms, which can lead to its being confused with other diseases such as tuberculosis or other forms of pneumonia. There are different forms of the disease, each with different symptoms.

• Localized infection: localized pain and swelling, fever, ulceration, and abscess.
• Pulmonary infection: cough, chest pain, high fever, headaches, and loss of appetite
• Bacteremia: fever, headaches, breathing problems, stomach discomfort, joint pain, and disorientation.
• Disseminated infection: fever, weight loss, stomach or chest pain, muscle or joint pain, headaches, central nervous system infections, and epileptic seizures.

The incubation time is not clearly defined and can be from 1 day to several years; however, the symptoms mostly emerge 2-4 weeks after exposure. The risk factors include diabetes, high alcohol consumption, chronic pulmonary or kidney disease, and immunodeficiencies.

Diagnosis based on the symptoms is often difficult since the clinical picture is similar to other, more common conditions.
 

Therapy

If the melioidosis is identified as such, it can be treated with only mildly effective antibiotics, since it has a natural resistance to many commonly used antibiotics. The type of infection and the course of treatment also affects the long-term outcome. Without treatment, 90% of the infections have a fatal outcome. With appropriate treatment, the mortality rate still lies at 40%.

Therapy generally begins with intravenous antibiotic therapy for at least 2-8 weeks (ceftazidime or meropenem). Oral antibiotic therapy then follows for 3-6 months (trimethoprim-sulfamethoxazole or amoxicillin/clavulanic acid). If the patient is allergic to penicillin, alternative antibiotics can be used.
 

Use as a bioweapon

The CDC classifies B. pseudomallei as a potential pathogen for biological attack (class-B candidate). The agency lists the potential reasons for use as a bioweapon as:

• The pathogen can be found naturally in certain regions.
• The triggered disease can take a serious course and ultimately be fatal without appropriate therapy.
• In the past, the United States has used similar pathogens in wars as bioweapons.

In a potential attack, the pathogen could be spread through air, water, or food, and by doing so, many people would be exposed. Any contact with the bacteria can result in melioidosis. As the bacteria cannot be seen, smelled, or tasted, the biological attack would not be recognized for some time. A certain amount of time can also pass until the pathogen is identified, once fever and respiratory diseases have developed.

In such an emergency, the CDC would collaborate with other federal and local authorities to supply specialized testing laboratories and provide the public with information.

In this randomized, double-blind, placebo-controlled study, the primary outcome will be to determine if treating Pneumocystis jirovecii in acute exacerbations of COPD with confirmed P. jirovecii colonization has a beneficial clinical impact. As a secondary goal of the study, it will be determined if the addition of trimethoprim-sulfamethoxazole (TMP-SMX) to standard of care can decolonize these patients and if the decolonization is durable for at least 3 months.
 

A total of 30 participants aged 40-89 years will be randomized to receive either a suspension with the equivalent of one double-strength TMP-SMX or a suspension with placebo by mouth every 12 hours. If the participant is discharged prior to completing the 10-day course of the medication, they will be sent home with the remaining study medication and a medication diary which will be collected.

Inter-lobar Fissure Completion in Patients With Failed Bronchoscopic Lung Volume Reduction (SAVED-1): NCT05257681

This study is intended to be a pilot prospective controlled clinical trial to evaluate the potential role of a lung fissure completion with pleural adhesiolysis strategy (experimental intervention) in severe emphysema/COPD patients with failed bronchoscopic lung volume reduction via the use of endobronchial valves therapy.

In 20 select patients (ages 40-75 years), the lung fissure completion with adhesiolysis strategy will be performed by video-assisted thoracoscopic surgery guided stapling along the lung fissures to reduce collateral ventilation with adhesions removal. The primary outcomes will be to prove that interlobar fissures can be completed to at least 95% in severe emphysema patients with previously failed bronchoscopic lung volume reduction over a 2 year period and the occurrence of adverse events in that period. The surgery will be considered feasible if the target inter-lobar fissure can be completed in at least 90% of the patients enrolled. Secondary outcomes over 2 years will include quality of life improvement and the percentage of patients with significant changes in pulmonary function testing.

Case Example

A 37-year-old female never smoker presents to your clinic with progressive dyspnea over the past 15 years. She reports dyspnea on exertion, wheezing, chronic nasal congestion, and difficulty sleeping that started a year after she returned from military deployment to Iraq. She has been unable to exercise, even at low intensity, for the past 5 years, despite being previously active. She has experienced some symptom improvement by taking an albuterol inhaler as needed, loratadine (10 mg), and fluticasone nasal spray (50 mcg). She occasionally uses famotidine for reflux (40 mg). She deployed to Southwest Asia for 12 months (2002-2003) and was primarily stationed in Qayyarah West, an Air Force base in the Mosul district in northern Iraq. She reports exposure during deployment to the fire in the Al-Mishraq sulfur mine, located approximately 25 km north of Qayyarah West, as well as dust storms and burn pits. She currently works as a medical assistant. Her examination is remarkable for normal bronchovesicular breath sounds without any wheezing or crackles on pulmonary evaluation. Her body mass index is 31. You obtain a chest radiograph and spirometry, which are both normal.

The veteran reports feeling frustrated as she has had multiple specialty evaluations in community clinics without receiving a diagnosis, despite worsening symptoms. She reports that she added her information to the Airborne Hazards and Open Burn Pit Registry (AHOBPR). She recently received a letter from the US Department of Veterans Affairs (VA) Post-Deployment Cardiopulmonary Evaluation Network (PDCEN) and is asking you whether she should participate in the PDCEN specialty evaluation. You are not familiar with the military experiences she has described or the programs she asks you about; however, you would like to know more to best care for your patient.

Background

The year 2021 marked the 20th anniversary of the September 11 attacks and the launch of the Global War on Terrorism. Almost 3 million US military personnel have been deployed in support of these operations along with about 300,000 US civilian contractors and thousands of troops from more than 40 nations.^1-3

Deployment after 2001 to Afghanistan and the Southwest Asia theater of operations, which includes but is not limited to Iraq, Kuwait, and Saudi Arabia, has been associated with increased prevalence of dyspnea and cough as well as diagnoses of asthma, chronic obstructive pulmonary disease (COPD), and other chronic respiratory diseases.^4-9 Expert committees convened by the National Academies of Sciences, Engineering, and Medicine concluded that deployment to the Southwest Asia region and Afghanistan was associated with respiratory symptoms of cough, wheeze, and shortness of breath and might be associated with long-term health effects, particularly in vulnerable (eg, individuals with asthma) or highly exposed populations (eg, those assigned to work at burn pits).^10,11 Several reports have found constrictive bronchiolitis, emphysema, granulomatous inflammation, and pigment deposition on lung biopsy in deployed persons with unexplained dyspnea and subtle, or normal, clinical findings.^12-14

Respiratory hazards associated with deployment to Southwest Asia and Afghanistan are unique and varied. These exposures include blast injuries and a variety of particulate matter sources, such as burn pit combustion byproducts, aeroallergens, and dust storms.^7,8,15,16 One air sampling study conducted at 15 deployment sites in Southwest Asia and Afghanistan found mean fine particulate matter (PM_2.5) levels were as much as 10 times greater than sampling sites in both rural and urban cities in the United States; all sites sampled exceeded military exposure guidelines (65 µg/m³ for 1 year).^17,18 Long-term exposure to PM_2.5 has been associated with the development of chronic respiratory and cardiovascular disease; therefore, there has been considerable attention to the respiratory (and nonrespiratory) health of deployed military personnel.¹⁹

Concerns regarding the association between deployment and lung disease led to the creation of the national VA Airborne Hazards and Open Burn Pit Registry (AHOBPR) in 2014 and consists of (1) an online questionnaire to document deployment and medical history, exposure concerns, and symptoms; and (2) an optional in-person or virtual clinical health evaluation at the individual’s local VA medical center or military treatment facility (MTF). As of March 2022, more than 300,000 individuals have completed the online questionnaire of which about 30% declined the optional clinical health evaluation.

The clinical evaluation available to AHOBPR participants has not yet been described in the literature. Therefore, our objectives are to examine AHOBPR clinical evaluation data and review its application throughout the VA. In addition, we will also describe a parallel effort by the VA PDCEN, which is to provide comprehensive multiday clinical evaluations for unique AHOBPR participants with unexplained dyspnea and self-reported respiratory disease. A secondary aim of this publication is to disseminate information to health care professionals (HCPs) within and outside of the VA to aid in the referral and evaluation of previously deployed veterans who experience unexplained dyspnea.

AHOBPR Overview

The AHOBPR is an online questionnaire and optional in-person health evaluation that includes 7 major categories targeting deployment history, symptoms, medical history, health concerns, residential history, nonmilitary occupational history, nonmilitary environmental exposures, and health care utilization. The VA Defense Information Repository is used to obtain service dates for the service member/veteran, conflict involvement, and primary location during deployment. The questionnaire portion of the AHOBPR is administered online. It currently is open to all veterans who served in the Southwest Asia theater of operations (including Iraq, Kuwait, and Egypt) any time after August 2, 1990, or Afghanistan, Djibouti, Syria, or Uzbekistan after September 11, 2001. Veterans are eligible for completing the AHOBPR and optional health evaluation at no cost to the veteran regardless of VA benefits or whether they are currently enrolled in VA health care. Though the focus of the present manuscript is to profile a VA program, it is important to note that the US Department of Defense (DoD) is an active partner with the VA in the promotion of the AHOBPR to service members and similarly provides health evaluations for active-duty service members (including activating Reserve and Guard) through their local MTF.

We reviewed and analyzed AHOBPR operations and VA data from 2014 to 2020. Our analyses were limited to veterans seeking evaluation as well as their corresponding symptoms and HCP’s clinical impression from the electronic health record. As of September 20, 2021, 267,125 individuals completed the AHOBPR. The mean age was 43 years (range, 19-84), and the majority were male (86%) and served in the Army (58%). Open-air burn pits (91%), engine maintenance (38.8%), and convoy operations (71.7%) were the most common deployment-related exposures.

The optional in-person AHOBPR health evaluation may be requested by the veteran after completing the online questionnaire and is performed at the veteran’s local VA facility. The evaluation is most often completed by an environmental health clinician or primary care practitioner (PCP). A variety of resources are available to providers for training on this topic, including fact sheets, webinars, monthly calls, conferences, and accredited e-learning.²⁰ As part of the clinical evaluation, the veteran’s chief concerns are assessed and evaluated. At the time of our analysis, 24,578 clinical examinations were performed across 126 VA medical facilities, with considerable geographic variation. Veterans receiving evaluations were predominantly male (89%) with a median age of 46.0 years (IQR, 15). Veterans’ major respiratory concerns included dyspnea (45.1%), decreased exercise ability (34.8%), and cough > 3 weeks (30.3%) (Table). After clinical evaluation by a VA or MTF HCP, 47.8% were found to have a respiratory diagnosis, including asthma (30.1%), COPD (12.8%), and bronchitis (11.9%).

Post-Deployment Cardiopulmonary Evaluation Network Clinical Evaluation

In May 2019, the VA established the Airborne Hazards and Burn Pits Center of Excellence (AHBPCE). One of the AHBPCE’s objectives is to deliver specialized care and consultation for veterans with concerns about their postdeployment health, including, but not limited to, unexplained dyspnea. To meet this objective, the AHBPCE developed the PDCEN, a national network consisting of specialty HCPs from 5 VA medical centers—located in San Francisco, California; Denver, Colorado; Baltimore, Maryland; Ann Arbor, Michigan; and East Orange, New Jersey. Collectively, the PDCEN has developed a standardized approach for the comprehensive clinical evaluation of unexplained dyspnea that is implemented uniformly across sites. Staff at the PDCEN screen the AHOBPR to identify veterans with features of respiratory disease and invite them to participate in an in-person evaluation at the nearest PDCEN site. Given the specialty expertise (detailed below) within the Network, the PDCEN focuses on complex cases that are resource intensive. To address complex cases of unexplained dyspnea, the PDCEN has developed a core clinical evaluation approach (Figure).

The first step in a veteran’s PDCEN evaluation entails a set of detailed questionnaires that request information about the veteran’s current respiratory, sleep, and mental health symptoms and any associated medical diagnoses. Questionnaires also identify potential exposures to military burn pits, sulfur mine and oil field fires, diesel exhaust fumes, dust storms, urban pollution, explosions/blasts, and chemical weapons. In addition, the questionnaires include deployment geographic location, which may inform future estimates of particulate matter exposure.²¹ Prior VA and non-VA evaluations and testing of their respiratory concerns are obtained for review. Exposure and health records from the DoD are also reviewed when available.

The next step in the PDCEN evaluation comprises comprehensive testing, including complete pulmonary function testing, methacholine challenge, cardiopulmonary exercise testing, forced oscillometry and exhaled nitric oxide testing, paired high-resolution inspiratory and expiratory chest computed tomography (CT) imaging, sinus CT imaging, direct flexible laryngoscopy, echocardiography, polysomnography, and laboratory blood testing. The testing process is managed by local site coordinators and varies by institution based on availability of each testing modality and subspecialist appointments.

Once testing is completed, the veteran is evaluated by a team of HCPs, including physicians from the disciplines of pulmonary medicine, environmental and occupational health, sleep medicine, otolaryngology and speech pathology, and mental health (when appropriate). After the clinical evaluation has been completed, this team of expert HCPs at each site convenes to provide a final summary review visit intended to be a comprehensive assessment of the veteran’s primary health concerns. The 3 primary objectives of this final review are to inform the veteran of (1) what respiratory and related conditions they have; (2) whether the conditions is/are deployment related; and (3) what treatments and/or follow-up care may enhance their current state of health in partnership with their local HCPs. The PDCEN does not provide ongoing management of any conditions identified during the veteran’s evaluation but communicates findings and recommendations to the veteran and their PCP for long-term care.

Discussion

The AHOBPR was established in response to mounting concerns that service members and veterans were experiencing adverse health effects that might be attributable to deployment-related exposures. Nearly half of all patients currently enrolled in the AHOBPR report dyspnea, and about one-third have decreased exercise tolerance and/or cough. Of those who completed the questionnaire and the subsequent in-person and generalized AHOBPR examination, our interim analysis showed that about half were assigned a respiratory diagnosis. Yet for many veterans, their breathing symptoms remained unexplained or did not respond to treatment.

While the AHOBPR and related examinations address the needs of many veterans, others may require more comprehensive examination. The PDCEN attends to the latter by providing more detailed and comprehensive clinical evaluations of veterans with deployment-related respiratory health concerns and seeks to learn from these evaluations by analyzing data obtained from veterans across sites. As such, the PDCEN hopes not only to improve the health of individual veterans, but also create standard practices for both VA and non-VA community evaluation of veterans exposed to respiratory hazards during deployment.

One of the major challenges in the field of postdeployment respiratory health is the lack of clear universal language or case definitions that encompass the veteran’s clinical concerns. In an influential case series published in 2011, 38 (77%) of 49 soldiers with history of airborne hazard exposure and unexplained exercise intolerance were reported to have histopathology consistent with constrictive bronchiolitis on surgical lung biopsy.¹⁴ Subsequent publications have described other histopathologic features in deployed military personnel, including granulomatous inflammation, interstitial lung disease, emphysema, and pleuritis.^12-14 Reconciling these findings from surgical lung biopsy with the clinical presentation and noninvasive studies has proved difficult. Therefore, several groups of investigators have proposed terms, including postdeployment respiratory syndrome, deployment-related distal lung disease, and Iraq/Afghanistan War lung injury to describe the increased respiratory symptoms and variety of histopathologic and imaging findings in this population.^9,12,22 At present, there remains a lack of consensus on terminology and case definitions as well as the role of military environmental exposures in exacerbating and/or causing these conditions. As HCPs, it is important to appreciate and acknowledge that the ambiguity and controversy pertaining to terminology, causation, and service connections are a common source of frustration experienced by veterans, which are increasingly reflected among reports in popular media and lay press.

A second and related challenge in the field of postdeployment respiratory health that contributes to veteran and HCP frustration is that many of the aforementioned abnormalities described on surgical lung biopsy are not readily identifiable on noninvasive tests, including traditional interpretation of pulmonary function tests or chest CT imaging.^12-14,22 Thus, underlying conditions could be overlooked and veterans’ concerns and symptoms may be dismissed or misattributed to other comorbid conditions. While surgical lung biopsies may offer diagnostic clarity in identifying lung disease, there are significant procedural risks of surgical and anesthetic complications. Furthermore, a definitive diagnosis does not necessarily guarantee a clear treatment plan. For example, there are no current therapies approved by the US Food and Drug Administration for the treatment of constrictive bronchiolitis.

Research efforts are underway, including within the PDCEN, to evaluate a more sensitive and noninvasive assessment of the small airways that may even reduce or eliminate the need for surgical lung biopsy. In contrast to traditional pulmonary function testing, which is helpful for evaluation of the larger airways, forced oscillation technique can be used noninvasively, using pressure oscillations to evaluate for diseases of the smaller airways and has been used in the veteran population and in those exposed to dust from the World Trade Center disaster.^23-25 Multiple breath washout technique provides a lung clearance index that is determined by the number of lung turnovers it takes to clear the lungs of an inert gas (eg, sulfur hexafluoride, nitrogen). Elevated lung clearance index values suggest ventilation heterogeneity and have been shown to be higher among deployed veterans with dyspnea.^26,27 Finally, advanced CT analytic techniques may help identify functional small airways disease and are higher in deployed service members with constrictive bronchiolitis on surgical lung biopsy.²⁸ These innovative noninvasive techniques are experimental but promising, especially as part of a broader evaluation of small airways disease.

AHOBPR clinical evaluations represent an initial step to better understand postdeployment health conditions available to all AHOBPR participants. The PDCEN clinical evaluation extends the AHOBPR evaluation by providing specialty care for certain veterans requiring more comprehensive evaluation while systematically collecting and analyzing clinical data to advance the field. The VA is committed to leveraging these data and all available expertise to provide a clear description of the spectrum of disease in this population and improve our ability to diagnose, follow, and treat respiratory health conditions occurring after deployment to Southwest Asia and Afghanistan.

Case Conclusion

The veteran was referred to a PDCEN site and underwent a comprehensive multidisciplinary evaluation. Pulmonary function testing showed lung volumes and vital capacity within the predicted normal range, mild air trapping, and a low diffusion capacity for carbon monoxide. Methacholine challenge testing was normal; however, forced oscillometry suggested small airways obstruction. A high-resolution CT showed air trapping without parenchymal changes. Cardiopulmonary exercise testing demonstrated a peak exercise capacity within the predicted normal range but low breathing reserve. Otolaryngology evaluation including laryngoscopy suggested chronic nonallergic rhinitis.

At the end of the veteran’s evaluation, a summary review reported nonallergic rhinitis and distal airway obstruction consistent with small airways disease. Both were reported as most likely related to deployment given her significant environmental exposures and the temporal relationship with her deployment and symptom onset as well as lack of other identifiable causes. A more precise histopathologic diagnosis could be firmly established with a surgical lung biopsy, but after shared decision making with a PDCEN HCP, the patient declined to undergo this invasive procedure. After you review the summary review and recommendations from the PDCEN group, you start the veteran on intranasal steroids and a combined inhaled corticosteroid/long-acting β agonist inhaler as well as refer the veteran to pulmonary rehabilitation. After several weeks, she reports an improvement in sleep and nasal symptoms but continues to experience residual exercise intolerance.

This case serves as an example of the significant limitations that a previously active and healthy patient can develop after deployment to Southwest Asia and Afghanistan. Encouraging this veteran to complete the AHOBPR allowed her to be considered for a PDCEN evaluation that provided the opportunity to undergo a comprehensive noninvasive evaluation of her chronic dyspnea. In doing so, she obtained 2 important diagnoses and data from her evaluation will help establish best practices for standardized evaluations of respiratory concerns following deployment. Through the AHOBPR and PDCEN, the VA seeks to better understand postdeployment health conditions, their relationship to military and environmental exposures, and how best to diagnose and treat these conditions.

Concerns regarding the association between deployment and lung disease led to the creation of the national VA Airborne Hazards and Open Burn Pit Registry (AHOBPR) in 2014 and consists of (1) an online questionnaire to document deployment and medical history, exposure concerns, and symptoms; and (2) an optional in-person or virtual clinical health evaluation at the individual’s local VA medical center or military treatment facility (MTF). As of March 2022, more than 300,000 individuals have completed the online questionnaire of which about 30% declined the optional clinical health evaluation.

The clinical evaluation available to AHOBPR participants has not yet been described in the literature. Therefore, our objectives are to examine AHOBPR clinical evaluation data and review its application throughout the VA. In addition, we will also describe a parallel effort by the VA PDCEN, which is to provide comprehensive multiday clinical evaluations for unique AHOBPR participants with unexplained dyspnea and self-reported respiratory disease. A secondary aim of this publication is to disseminate information to health care professionals (HCPs) within and outside of the VA to aid in the referral and evaluation of previously deployed veterans who experience unexplained dyspnea.

AHOBPR Overview

The AHOBPR is an online questionnaire and optional in-person health evaluation that includes 7 major categories targeting deployment history, symptoms, medical history, health concerns, residential history, nonmilitary occupational history, nonmilitary environmental exposures, and health care utilization. The VA Defense Information Repository is used to obtain service dates for the service member/veteran, conflict involvement, and primary location during deployment. The questionnaire portion of the AHOBPR is administered online. It currently is open to all veterans who served in the Southwest Asia theater of operations (including Iraq, Kuwait, and Egypt) any time after August 2, 1990, or Afghanistan, Djibouti, Syria, or Uzbekistan after September 11, 2001. Veterans are eligible for completing the AHOBPR and optional health evaluation at no cost to the veteran regardless of VA benefits or whether they are currently enrolled in VA health care. Though the focus of the present manuscript is to profile a VA program, it is important to note that the US Department of Defense (DoD) is an active partner with the VA in the promotion of the AHOBPR to service members and similarly provides health evaluations for active-duty service members (including activating Reserve and Guard) through their local MTF.

We reviewed and analyzed AHOBPR operations and VA data from 2014 to 2020. Our analyses were limited to veterans seeking evaluation as well as their corresponding symptoms and HCP’s clinical impression from the electronic health record. As of September 20, 2021, 267,125 individuals completed the AHOBPR. The mean age was 43 years (range, 19-84), and the majority were male (86%) and served in the Army (58%). Open-air burn pits (91%), engine maintenance (38.8%), and convoy operations (71.7%) were the most common deployment-related exposures.

The optional in-person AHOBPR health evaluation may be requested by the veteran after completing the online questionnaire and is performed at the veteran’s local VA facility. The evaluation is most often completed by an environmental health clinician or primary care practitioner (PCP). A variety of resources are available to providers for training on this topic, including fact sheets, webinars, monthly calls, conferences, and accredited e-learning.²⁰ As part of the clinical evaluation, the veteran’s chief concerns are assessed and evaluated. At the time of our analysis, 24,578 clinical examinations were performed across 126 VA medical facilities, with considerable geographic variation. Veterans receiving evaluations were predominantly male (89%) with a median age of 46.0 years (IQR, 15). Veterans’ major respiratory concerns included dyspnea (45.1%), decreased exercise ability (34.8%), and cough > 3 weeks (30.3%) (Table). After clinical evaluation by a VA or MTF HCP, 47.8% were found to have a respiratory diagnosis, including asthma (30.1%), COPD (12.8%), and bronchitis (11.9%).

Post-Deployment Cardiopulmonary Evaluation Network Clinical Evaluation

In May 2019, the VA established the Airborne Hazards and Burn Pits Center of Excellence (AHBPCE). One of the AHBPCE’s objectives is to deliver specialized care and consultation for veterans with concerns about their postdeployment health, including, but not limited to, unexplained dyspnea. To meet this objective, the AHBPCE developed the PDCEN, a national network consisting of specialty HCPs from 5 VA medical centers—located in San Francisco, California; Denver, Colorado; Baltimore, Maryland; Ann Arbor, Michigan; and East Orange, New Jersey. Collectively, the PDCEN has developed a standardized approach for the comprehensive clinical evaluation of unexplained dyspnea that is implemented uniformly across sites. Staff at the PDCEN screen the AHOBPR to identify veterans with features of respiratory disease and invite them to participate in an in-person evaluation at the nearest PDCEN site. Given the specialty expertise (detailed below) within the Network, the PDCEN focuses on complex cases that are resource intensive. To address complex cases of unexplained dyspnea, the PDCEN has developed a core clinical evaluation approach (Figure).

The first step in a veteran’s PDCEN evaluation entails a set of detailed questionnaires that request information about the veteran’s current respiratory, sleep, and mental health symptoms and any associated medical diagnoses. Questionnaires also identify potential exposures to military burn pits, sulfur mine and oil field fires, diesel exhaust fumes, dust storms, urban pollution, explosions/blasts, and chemical weapons. In addition, the questionnaires include deployment geographic location, which may inform future estimates of particulate matter exposure.²¹ Prior VA and non-VA evaluations and testing of their respiratory concerns are obtained for review. Exposure and health records from the DoD are also reviewed when available.

The next step in the PDCEN evaluation comprises comprehensive testing, including complete pulmonary function testing, methacholine challenge, cardiopulmonary exercise testing, forced oscillometry and exhaled nitric oxide testing, paired high-resolution inspiratory and expiratory chest computed tomography (CT) imaging, sinus CT imaging, direct flexible laryngoscopy, echocardiography, polysomnography, and laboratory blood testing. The testing process is managed by local site coordinators and varies by institution based on availability of each testing modality and subspecialist appointments.

Once testing is completed, the veteran is evaluated by a team of HCPs, including physicians from the disciplines of pulmonary medicine, environmental and occupational health, sleep medicine, otolaryngology and speech pathology, and mental health (when appropriate). After the clinical evaluation has been completed, this team of expert HCPs at each site convenes to provide a final summary review visit intended to be a comprehensive assessment of the veteran’s primary health concerns. The 3 primary objectives of this final review are to inform the veteran of (1) what respiratory and related conditions they have; (2) whether the conditions is/are deployment related; and (3) what treatments and/or follow-up care may enhance their current state of health in partnership with their local HCPs. The PDCEN does not provide ongoing management of any conditions identified during the veteran’s evaluation but communicates findings and recommendations to the veteran and their PCP for long-term care.

Discussion

The AHOBPR was established in response to mounting concerns that service members and veterans were experiencing adverse health effects that might be attributable to deployment-related exposures. Nearly half of all patients currently enrolled in the AHOBPR report dyspnea, and about one-third have decreased exercise tolerance and/or cough. Of those who completed the questionnaire and the subsequent in-person and generalized AHOBPR examination, our interim analysis showed that about half were assigned a respiratory diagnosis. Yet for many veterans, their breathing symptoms remained unexplained or did not respond to treatment.

While the AHOBPR and related examinations address the needs of many veterans, others may require more comprehensive examination. The PDCEN attends to the latter by providing more detailed and comprehensive clinical evaluations of veterans with deployment-related respiratory health concerns and seeks to learn from these evaluations by analyzing data obtained from veterans across sites. As such, the PDCEN hopes not only to improve the health of individual veterans, but also create standard practices for both VA and non-VA community evaluation of veterans exposed to respiratory hazards during deployment.

One of the major challenges in the field of postdeployment respiratory health is the lack of clear universal language or case definitions that encompass the veteran’s clinical concerns. In an influential case series published in 2011, 38 (77%) of 49 soldiers with history of airborne hazard exposure and unexplained exercise intolerance were reported to have histopathology consistent with constrictive bronchiolitis on surgical lung biopsy.¹⁴ Subsequent publications have described other histopathologic features in deployed military personnel, including granulomatous inflammation, interstitial lung disease, emphysema, and pleuritis.^12-14 Reconciling these findings from surgical lung biopsy with the clinical presentation and noninvasive studies has proved difficult. Therefore, several groups of investigators have proposed terms, including postdeployment respiratory syndrome, deployment-related distal lung disease, and Iraq/Afghanistan War lung injury to describe the increased respiratory symptoms and variety of histopathologic and imaging findings in this population.^9,12,22 At present, there remains a lack of consensus on terminology and case definitions as well as the role of military environmental exposures in exacerbating and/or causing these conditions. As HCPs, it is important to appreciate and acknowledge that the ambiguity and controversy pertaining to terminology, causation, and service connections are a common source of frustration experienced by veterans, which are increasingly reflected among reports in popular media and lay press.

A second and related challenge in the field of postdeployment respiratory health that contributes to veteran and HCP frustration is that many of the aforementioned abnormalities described on surgical lung biopsy are not readily identifiable on noninvasive tests, including traditional interpretation of pulmonary function tests or chest CT imaging.^12-14,22 Thus, underlying conditions could be overlooked and veterans’ concerns and symptoms may be dismissed or misattributed to other comorbid conditions. While surgical lung biopsies may offer diagnostic clarity in identifying lung disease, there are significant procedural risks of surgical and anesthetic complications. Furthermore, a definitive diagnosis does not necessarily guarantee a clear treatment plan. For example, there are no current therapies approved by the US Food and Drug Administration for the treatment of constrictive bronchiolitis.

Research efforts are underway, including within the PDCEN, to evaluate a more sensitive and noninvasive assessment of the small airways that may even reduce or eliminate the need for surgical lung biopsy. In contrast to traditional pulmonary function testing, which is helpful for evaluation of the larger airways, forced oscillation technique can be used noninvasively, using pressure oscillations to evaluate for diseases of the smaller airways and has been used in the veteran population and in those exposed to dust from the World Trade Center disaster.^23-25 Multiple breath washout technique provides a lung clearance index that is determined by the number of lung turnovers it takes to clear the lungs of an inert gas (eg, sulfur hexafluoride, nitrogen). Elevated lung clearance index values suggest ventilation heterogeneity and have been shown to be higher among deployed veterans with dyspnea.^26,27 Finally, advanced CT analytic techniques may help identify functional small airways disease and are higher in deployed service members with constrictive bronchiolitis on surgical lung biopsy.²⁸ These innovative noninvasive techniques are experimental but promising, especially as part of a broader evaluation of small airways disease.

AHOBPR clinical evaluations represent an initial step to better understand postdeployment health conditions available to all AHOBPR participants. The PDCEN clinical evaluation extends the AHOBPR evaluation by providing specialty care for certain veterans requiring more comprehensive evaluation while systematically collecting and analyzing clinical data to advance the field. The VA is committed to leveraging these data and all available expertise to provide a clear description of the spectrum of disease in this population and improve our ability to diagnose, follow, and treat respiratory health conditions occurring after deployment to Southwest Asia and Afghanistan.

Case Conclusion

The veteran was referred to a PDCEN site and underwent a comprehensive multidisciplinary evaluation. Pulmonary function testing showed lung volumes and vital capacity within the predicted normal range, mild air trapping, and a low diffusion capacity for carbon monoxide. Methacholine challenge testing was normal; however, forced oscillometry suggested small airways obstruction. A high-resolution CT showed air trapping without parenchymal changes. Cardiopulmonary exercise testing demonstrated a peak exercise capacity within the predicted normal range but low breathing reserve. Otolaryngology evaluation including laryngoscopy suggested chronic nonallergic rhinitis.

At the end of the veteran’s evaluation, a summary review reported nonallergic rhinitis and distal airway obstruction consistent with small airways disease. Both were reported as most likely related to deployment given her significant environmental exposures and the temporal relationship with her deployment and symptom onset as well as lack of other identifiable causes. A more precise histopathologic diagnosis could be firmly established with a surgical lung biopsy, but after shared decision making with a PDCEN HCP, the patient declined to undergo this invasive procedure. After you review the summary review and recommendations from the PDCEN group, you start the veteran on intranasal steroids and a combined inhaled corticosteroid/long-acting β agonist inhaler as well as refer the veteran to pulmonary rehabilitation. After several weeks, she reports an improvement in sleep and nasal symptoms but continues to experience residual exercise intolerance.

This case serves as an example of the significant limitations that a previously active and healthy patient can develop after deployment to Southwest Asia and Afghanistan. Encouraging this veteran to complete the AHOBPR allowed her to be considered for a PDCEN evaluation that provided the opportunity to undergo a comprehensive noninvasive evaluation of her chronic dyspnea. In doing so, she obtained 2 important diagnoses and data from her evaluation will help establish best practices for standardized evaluations of respiratory concerns following deployment. Through the AHOBPR and PDCEN, the VA seeks to better understand postdeployment health conditions, their relationship to military and environmental exposures, and how best to diagnose and treat these conditions.

Case Example

A 37-year-old female never smoker presents to your clinic with progressive dyspnea over the past 15 years. She reports dyspnea on exertion, wheezing, chronic nasal congestion, and difficulty sleeping that started a year after she returned from military deployment to Iraq. She has been unable to exercise, even at low intensity, for the past 5 years, despite being previously active. She has experienced some symptom improvement by taking an albuterol inhaler as needed, loratadine (10 mg), and fluticasone nasal spray (50 mcg). She occasionally uses famotidine for reflux (40 mg). She deployed to Southwest Asia for 12 months (2002-2003) and was primarily stationed in Qayyarah West, an Air Force base in the Mosul district in northern Iraq. She reports exposure during deployment to the fire in the Al-Mishraq sulfur mine, located approximately 25 km north of Qayyarah West, as well as dust storms and burn pits. She currently works as a medical assistant. Her examination is remarkable for normal bronchovesicular breath sounds without any wheezing or crackles on pulmonary evaluation. Her body mass index is 31. You obtain a chest radiograph and spirometry, which are both normal.

The veteran reports feeling frustrated as she has had multiple specialty evaluations in community clinics without receiving a diagnosis, despite worsening symptoms. She reports that she added her information to the Airborne Hazards and Open Burn Pit Registry (AHOBPR). She recently received a letter from the US Department of Veterans Affairs (VA) Post-Deployment Cardiopulmonary Evaluation Network (PDCEN) and is asking you whether she should participate in the PDCEN specialty evaluation. You are not familiar with the military experiences she has described or the programs she asks you about; however, you would like to know more to best care for your patient.

Background

The year 2021 marked the 20th anniversary of the September 11 attacks and the launch of the Global War on Terrorism. Almost 3 million US military personnel have been deployed in support of these operations along with about 300,000 US civilian contractors and thousands of troops from more than 40 nations.^1-3

Deployment after 2001 to Afghanistan and the Southwest Asia theater of operations, which includes but is not limited to Iraq, Kuwait, and Saudi Arabia, has been associated with increased prevalence of dyspnea and cough as well as diagnoses of asthma, chronic obstructive pulmonary disease (COPD), and other chronic respiratory diseases.^4-9 Expert committees convened by the National Academies of Sciences, Engineering, and Medicine concluded that deployment to the Southwest Asia region and Afghanistan was associated with respiratory symptoms of cough, wheeze, and shortness of breath and might be associated with long-term health effects, particularly in vulnerable (eg, individuals with asthma) or highly exposed populations (eg, those assigned to work at burn pits).^10,11 Several reports have found constrictive bronchiolitis, emphysema, granulomatous inflammation, and pigment deposition on lung biopsy in deployed persons with unexplained dyspnea and subtle, or normal, clinical findings.^12-14

Respiratory hazards associated with deployment to Southwest Asia and Afghanistan are unique and varied. These exposures include blast injuries and a variety of particulate matter sources, such as burn pit combustion byproducts, aeroallergens, and dust storms.^7,8,15,16 One air sampling study conducted at 15 deployment sites in Southwest Asia and Afghanistan found mean fine particulate matter (PM_2.5) levels were as much as 10 times greater than sampling sites in both rural and urban cities in the United States; all sites sampled exceeded military exposure guidelines (65 µg/m³ for 1 year).^17,18 Long-term exposure to PM_2.5 has been associated with the development of chronic respiratory and cardiovascular disease; therefore, there has been considerable attention to the respiratory (and nonrespiratory) health of deployed military personnel.¹⁹

Concerns regarding the association between deployment and lung disease led to the creation of the national VA Airborne Hazards and Open Burn Pit Registry (AHOBPR) in 2014 and consists of (1) an online questionnaire to document deployment and medical history, exposure concerns, and symptoms; and (2) an optional in-person or virtual clinical health evaluation at the individual’s local VA medical center or military treatment facility (MTF). As of March 2022, more than 300,000 individuals have completed the online questionnaire of which about 30% declined the optional clinical health evaluation.

The clinical evaluation available to AHOBPR participants has not yet been described in the literature. Therefore, our objectives are to examine AHOBPR clinical evaluation data and review its application throughout the VA. In addition, we will also describe a parallel effort by the VA PDCEN, which is to provide comprehensive multiday clinical evaluations for unique AHOBPR participants with unexplained dyspnea and self-reported respiratory disease. A secondary aim of this publication is to disseminate information to health care professionals (HCPs) within and outside of the VA to aid in the referral and evaluation of previously deployed veterans who experience unexplained dyspnea.

Pulse oximetry is a vital monitoring tool in the ICU and in pulmonary medicine. Regrettably, re-emerging data show that pulse oximeters do not accurately measure blood oxygen levels in Black patients, presumably due to their skin tone. Patients with darker skin are, therefore, more likely to experience occult hypoxemia (i.e., low arterial oxygen saturation despite a seemingly normal pulse oximetry reading). While inaccuracy of pulse oximeter measurements in patients with darker skin has been recognized for decades, recent studies have highlighted this as an ongoing problem with potentially severe consequences for Black patients and other patients of color.

One recent study found that Black patients had almost three times the likelihood of occult hypoxemia compared with White patients (Sjoding, MW, et al. N Engl J Med. 2020;383[25]:2477-8).

Subsequent studies have confirmed this to be a widespread problem across various clinical settings in hundreds of hospitals (Wong AI, et al. JAMA Netw Open. 2021;4[11]:e2131674; Valbuena VS, et al. Chest. 2022;161[4]:971-8). A recent retrospective cohort study of patients with COVID-19 found that occult hypoxemia in Black and Hispanic patients was associated with delayed eligibility for potentially lifesaving COVID-19 therapies (Fawzy AF, et al. JAMA Intern Med. 2022; published online May 31, 2022).

Now that numerous studies have demonstrated the inaccuracy of pulse oximetry with the potential to cause harm to historically marginalized racial and ethnic groups, must we abandon the use of pulse oximetry? We would argue that pulse oximeters remain valuable tools, but for now, we must adapt our practice until better devices are widely adopted.

First, it is crucial that health professionals are aware that pulse oximeters may underestimate the true extent of hypoxemia for all patients, but particularly for patients with darker skin. Acknowledging this device flaw is essential to avoid harm to our patients.

Second, clinicians must have heightened skepticism for seemingly normal pulse oximetry values when caring for symptomatic patients at risk of occult hypoxemia.

Until better pulse oximeters are widely available, clinicians must consider workarounds aimed at ensuring timely identification of hypoxemia in Black patients and other patients of color.

These patients may need invasive monitoring of arterial oxygenation, including arterial blood gas checks or an arterial catheter. However, invasive monitoring comes at the cost of discomfort to patients and potential complications, such as vessel or nerve damage.

Invasive monitoring of patients at risk for occult hypoxemia is not an equitable or acceptable long-term solution for this problem. As advocates for patients, clinicians and professional organizations should lobby regulatory bodies to ensure pulse oximeters are accurate for all patients.

We must also call on government leaders to move this process forward. For example, in response to efforts by the United Kingdom’s Intensive Care Society, the Health Secretary of the UK, Sajid Javid, has called for a review of pulse oximeters as part of a larger review assessing structural issues in health care that lead to worse outcomes in racial and ethnic minorities (BBC News. https://www.bbc.com/news/uk-59363544. Published online Nov. 21, 2021).

Device companies are largely for-profit corporations with obligations to their shareholders. It seems that existing incentives are insufficient to motivate investment in less biased technology and real-world evaluations of their devices.

We previously called for buyers of pulse oximeters to change the incentives of device companies – that is, for “hospitals to commit to only purchasing pulse oximeters that have been shown to work equally well in patients of colour.” (Hidalgo DC, et al. Lancet Respir Med. 2021;9[4]:E37). And, indeed, we worry that hospitals are putting themselves at medicolegal risk by not raising their purchasing standards. Since it is now widely known that pulse oximeters are inaccurate in certain patients, could there be liability for hospitals that continue to use devices we know to be disproportionately inaccurate by race?

Pulse oximetry is a vital monitoring tool in the ICU and in pulmonary medicine. Regrettably, re-emerging data show that pulse oximeters do not accurately measure blood oxygen levels in Black patients, presumably due to their skin tone. Patients with darker skin are, therefore, more likely to experience occult hypoxemia (i.e., low arterial oxygen saturation despite a seemingly normal pulse oximetry reading). While inaccuracy of pulse oximeter measurements in patients with darker skin has been recognized for decades, recent studies have highlighted this as an ongoing problem with potentially severe consequences for Black patients and other patients of color.

One recent study found that Black patients had almost three times the likelihood of occult hypoxemia compared with White patients (Sjoding, MW, et al. N Engl J Med. 2020;383[25]:2477-8).

Subsequent studies have confirmed this to be a widespread problem across various clinical settings in hundreds of hospitals (Wong AI, et al. JAMA Netw Open. 2021;4[11]:e2131674; Valbuena VS, et al.

The Pulmonary Fibrosis Foundation (PFF) has launched a new initiative in which they hope to capture a far more diverse representation of patients with pulmonary fibrosis (PF) than the current registry allows them to do, a press release from the PFF indicated.

“The existing registry we have – the PFF Patient Registry – is limited to our care centers, which are primarily academic clinical institutions and we have only a few thousand patients within that registry,” Junelle Speller, MBA, vice president of the PFF Registry, told this news organization.

“We wanted to go beyond these care centers and capture patients in community centers, and in rural settings to provide a more complete understanding of patients with this disease and, of course, have a larger sample size,” she added.

“So, the major impetus behind the PFF Community Registry was to gather a more diverse representative sample of PF patients across all parts of the United States and, most importantly, accelerate the research on PF toward improving earlier diagnosis, treatment, and outcomes for these patients,” Ms. Speller said.
 

Passive versus active

The PFF Community Registry differs in its structure and purpose from the PFF Patient Registry, as Ms. Speller explained. First, the PFF Patient Registry, established in 2016, is “passive” in its nature in that whatever information is entered into a patient’s electronic medical record or clinical chart on a routine office visit is abstracted and captured in the registry. By contrast, the PFF Community Registry is asking for self-reported data from patients, “so it’s more of an ‘active’ registry and will give us a chance to have a bidirectional connection with participants, provide email updates and newsletters, and give patients an opportunity to participate in future studies within the registry as well as in clinical trials,” she noted.

The two registries still overlap in that both capture demographic data on patients’ medical and family histories as well as any medications patients may be taking, but the Community Registry will also capture information with respect to education, employment, patient-reported outcomes, and quality of life metrics. “It will also let us know how patients feel about continued education on the disease itself and patient participation in support groups,” Ms. Speller observed.

The Community Registry will also collect information from lung transplant recipients who have had PF or any other form of interstitial lung disease (ILD) as well as information from caregivers and family members affected by the patient’s disease. As Ms. Speller noted, both PF and other forms of ILD (of which there are more than 200 types) are all characterized by inflammation or scarring in the lung. “Patients are often misdiagnosed, and it can take months, even years, to identify the disease,” Ms. Speller said.

From there, it can be a very long and difficult road ahead, with no cure in sight, although several antifibrotic drugs do help slow disease progression. Typically, onset is around the age of 60 and symptoms include chronic dry cough, fatigue, shortness of breath, weakness, discomfort in the chest, and sometimes unexplained weight loss. Some patients do have a history of smoking, but not all, Ms. Speller noted. So far, registry data suggest PF largely occurs in White patients.

“We’re very excited about the Community Registry, particularly about reaching into communities that we haven’t been able to reach with our existing registry,” Ms. Speller noted. “The rural population in particular is often underserved, so we are really looking forward to capturing data from these patients as well as those from community centers within smaller and larger cities,” she observed.

“A powerful aspect of the Community Registry is that we can use the information gained from it to understand the experience of individuals living with PF, and how it impacts their lives and those of their families and caregivers,” Kevin Flaherty, MD, steering committee chair, PFF Registry, said in a statement.

“Researchers can also look at the data to better understand fibrotic lung diseases and learn about effective approaches to improve patient care,” he added.

Patients who wish to join the PFF Community Registry can sign up at pffregistry.org. To learn more about PF and its risk factors, readers are invited to visit www.AboutPF.org. More than 250,000 patients in the United States are living with either PF or other types of ILD.

Ms. Speller and Dr. Flaherty disclosed no financial conflicts of interest. The PFF Registry is supported by its founding partner, Genentech, Visionary Partner, United Therapeutics, and its sustaining partner, Boehringer Ingelheim, as well as many donors.
