Concomitant rhinosinusitis without nasal polyps (RSsNP) in patients with chronic obstructive pulmonary disease (COPD) is associated with a poorer, disease-specific, health-related quality of life (HRQoL), a Norwegian study is showing.

“Chronic rhinosinusitis has an impact on patients’ HRQoL,” lead author Marte Rystad Øie, Trondheim (Norway) University Hospital, said in an interview.

“We found that RSsNP in COPD was associated with more psychological issues, higher COPD symptom burden, and overall COPD-related HRQoL after adjusting for lung function, so RSsNP does have clinical relevance and [our findings] support previous studies that have suggested that rhinosinusitis should be recognized as a comorbidity in COPD,” she emphasized.

The study was published in the Nov. 1 issue of Respiratory Medicine.
 

Study sample

The study sample consisted of 90 patients with COPD and 93 control subjects, all age 40-80 years. “Generic HRQoL was measured with the Norwegian version of the SF-36v2 Health Survey Standard questionnaire,” the authors wrote, and responses were compared between patients with COPD and controls as well as between subgroups of patients who had COPD both with and without RSsNP.

Disease-specific HRQoL was assessed by the Sinonasal Outcome Test-22 (SNOT-22); the St. Georges Respiratory Questionnaire (SGRQ), and the COPD Assessment Test (CAT), and responses were again compared between patients who had COPD with and without RSsNP. In the COPD group, “severe” and “very severe” airflow obstruction was present in 56.5% of patients with RSsNP compared with 38.6% of patients without RSsNP, as Ms. Øie reported.

Furthermore, total SNOT-22 along with psychological subscale scores were both significantly higher in patients who had COPD with RSsNP than those without RSsNP. Among those with RSsNP, the mean value of the total SNOT-22 score was 36.8 whereas the mean value of the psychological subscale score was 22.6. Comparable mean values among patients who had COPD without RSsNP were 9.5 and 6.5, respectively (P < .05).

Total scores on the SGRQ were again significantly greater in patients who had COPD with RSsNP at a mean of 43.3 compared with a mean of 34 in those without RSsNP, investigators observe. Similarly, scores for the symptom and activity domains again on the SGRQ were significantly greater for patients who had COPD with RSsNP than those without nasal polyps. As for the total CAT score, once again it was significantly higher in patients who had COPD with RSsNP at a mean of 18.8 compared with a mean of 13.5 in those without RSsNP (P < .05).

Indeed, patients with RSsNP were four times more likely to have CAT scores indicating the condition was having a high or very high impact on their HRQoL compared with patients without RSsNP (P < .001). As the authors pointed out, having a high impact on HRQoL translates into patients having to stop their desired activities and having no good days in the week.

“This suggests that having RSsNP substantially adds to the activity limitation experienced by patients with COPD,” they emphasized. The authors also found that RSsNP was significantly associated with poorer physical functioning after adjusting for COPD as reflected by SF-36v2 findings, again suggesting that patients who had COPD with concomitant RSsNP have an additional limitation in activity and a heavier symptom burden.

As Ms. Øie explained, rhinosinusitis has two clinical phenotypes: that with nasal polyps and that without nasal polyps, the latter being twice as prevalent. In fact, rhinosinusitis with nasal polyps is associated with asthma, as she pointed out. Given, however, that rhinosinusitis without polyps is amenable to treatment with daily use of nasal steroids, it is possible to reduce the burden of symptoms and psychological stress associated with RSsNP in COPD.

Limitations of the study include the fact that investigators did not assess patients for the presence of any comorbidities that could contribute to poorer HRQoL in this patient population.

The study was funded by Liaison Committee between the Central Norway Regional Health Authority and the Norwegian University of Science and Technology. The authors have disclosed no relevant financial relationships.

The Food and Drug Administration has given the green light to third, or booster doses of the Pfizer and Moderna vaccines for everyone over the age of 18, ahead of the busy winter holiday season.

“Authorizing the use of a single booster dose of either the Moderna or Pfizer-BioNTech COVID-19 vaccine for individuals 18 years of age and older helps to provide continued protection against COVID-19, including the serious consequences that can occur, such as hospitalization and death,” said acting FDA Commissioner Janet Woodcock, MD, in an FDA press statement.

The Center for Disease Control and Prevention’s Advisory Committee on Immunization Practices will meet on Nov. 19 to review the science supporting a more widespread need for booster doses, and is expected to vote on official recommendations for their use in the United States. The CDC director must then sign off on the panel’s recommendations.

“As soon as the FDA reviews those data and provides an authorization, we at CDC will act swiftly,” Rochelle P. Walensky, MD, MPH, said at a recent White House briefing.

Several states – including Louisiana, Maine, and Colorado – have already authorized boosters for all adults as cases rise in Europe and across the Western and Northeastern regions of the United States.

FDA officials said they hoped that widening eligibility for boosters would cut down on confusion for people and hopefully speed uptake of the shots.

“Streamlining the eligibility criteria and making booster doses available to all individuals 18 years of age and older will also help to eliminate confusion about who may receive a booster dose and ensure booster doses are available to all who may need one,” said Peter Marks, MD, PhD, who heads the FDA’s Center for Biologics Evaluation and Research.

When people wear face masks to reduce the spread of the coronavirus, the number of new COVID-19 infections drops by 53%, according to a new study published Nov. 18 in the British Medical Journal.

Social distancing and handwashing were also effective at lowering the number of cases, but wearing masks was the most effective tool against the coronavirus.

“Personal and social measures, including handwashing, mask wearing, and physical distancing are effective at reducing the incidence of COVID-19,” the study authors wrote.

The research team, which included public health and infectious disease specialists in Australia, China, and the U.K., evaluated 72 studies of COVID-19 precautions during the pandemic. They later looked at eight studies that focused on handwashing, mask wearing, and physical distancing.

Among six studies that looked at mask wearing, the researchers found a 53% reduction in COVID-19 cases. In the broader analysis with additional studies, wearing a mask reduced coronavirus transmission, cases, and deaths.

In one study across 200 countries, mandatory mask wearing resulted in nearly 46% fewer negative outcomes from COVID-19. In another study in the U.S., coronavirus transmission was reduced 29% in states where masks were mandatory.

But the research team couldn’t analyze the impact of the type of face mask used, the frequency of mask wearing, or the overall compliance with wearing face masks.

Among five studies that looked at physical distancing, the researchers found a 25% reduction in the rate of COVID-19. A study in the U.S. showed a 12% decrease in coronavirus transmission, while another study in Iran reported a reduction in COVID-19 mortality.

Handwashing interventions also suggested a substantial reduction of COVID-19 cases up to 53%, the researchers wrote. But in adjusted models, the results weren’t statistically significant due to the small number of studies included.

Other studies found significant decreases related to other public health measures, such as quarantines, broad lockdowns, border closures, school closures, business closures, and travel restrictions. Still, the research team couldn’t analyze the overall effectiveness of these measures due to the different ways the studies were conducted.

The study lines up with other research conducted so far during the pandemic, the research team wrote, which indicates that wearing masks and physical distancing can reduce transmission, cases, and deaths.

That said, more studies are needed, particularly now that vaccinations are available and contagious coronavirus variants have become prevalent.

“Further research is needed to assess the effectiveness of public health measures after adequate vaccination coverage has been achieved,” they wrote.

“It is likely that further control of the COVID-19 pandemic depends not only on high vaccination coverage and its effectiveness but also on ongoing adherence to effective and sustainable public health measures,” they concluded.

Holiday travel season is right around the corner, but coronavirus cases have already started to climb. But a new automated texting system could relieve pressure on emergency departments and reduce mortality rates if there were an uptick in COVID-19 this winter.

COVID Watch, a text message–based remote monitoring program developed by the University of Pennsylvania Health System, was associated with a 68% reduction in the risk of death, compared with those who received usual care. This was the main finding of a paper published in the Annals of Internal Medicine.

The investigators also determined that patients who enrolled in the program were more likely to seek care in the ED and when they did, they came in on average 2 days sooner than those who received usual care.

“When our clinical team designed COVID Watch the goal was to facilitate hospital care for patients who require it, while supporting access to care for patients who can safely remain at home,” study author M. Kit Delgado, MD, MS, an assistant professor of emergency medicine and epidemiology at Penn Presbyterian Medical Center in Philadelphia, said in an interview.

Researchers had initially hoped COVID Watch would relieve pressure on EDs, Dr. Delgado said.
 

Significantly lower mortality seen among COVID Watch group

For the study, Dr. Delgado and colleagues enrolled 3,488 patients in COVID Watch and 4,377 in the usual care group to compare outcomes at 30 and 60 days.

“We didn’t include patients who were diagnosed with COVID in the ER or hospital, so this is a lower-risk cohort of patients who test positive in outpatient settings,” Dr. Delgado noted. “Outpatients who received usual care and COVID Watch both had relatively low mortality, but it was significantly lower in those who were in COVID Watch.”

The researchers found that 3 patients in the COVID Watch group died within 30 days of their enrollment, compared with 12 in the control group. At 60 days after enrollment, 5 people within COVID Watch died, compared with 16 not using the system. More than one-third of the deaths in the usual care group occurred outside the hospital, compared with zero deaths among those in COVID Watch.
 

More than half of program participants were Black or Latino

The messaging system also reduced mortality rates among “all major racial and ethnic subgroups,” the researchers said, with more than 50% of the patients enrolled in COVID Watch having been Black or Latino.

“This is important because Black and Hispanic communities have experienced higher exposure and infection rates, decreased access to care, and have had higher mortality rates,” Dr. Delgado said. “Therefore, the results imply that this type of program could play a role in decreasing disparities in COVID outcomes if scaled more broadly.”
 

Outside expert: COVID Watch bring new approach to digital health monitoring

The study not only highlights the efficacy and sustainment of the COVID Watch program, but it sheds light on the possibility of using text message monitoring systems on other chronic disease conditions, said Jamie Faro, PhD, who was not involved in the study.

“It brings a new approach to health monitoring using digital means, which may lessen the burden on health care providers and be more cost effective than usual care approaches,” said Dr. Faro, who is assistant professor at the department of population and quantitative health sciences at the University of Massachusetts, Worcester. “Text messaging, which is used by over 80% of Americans, can allow us to reach a large percentage of the population for remote health care monitoring.”

Researchers of the current study said the findings “reveal a model for outpatient health system management of patients with COVID-19 and possibly other conditions where the early detection of clinical declines is critical.” Dr. Faro said that COVID Watch can have a measurable impact on an outcome that is truly life or death. However, it would be critical to understand how to reach those who either “were not offered or refused to take part in the program.”

The authors of the paper and Dr. Faro had no disclosures.

More than half of program participants were Black or Latino

The messaging system also reduced mortality rates among “all major racial and ethnic subgroups,” the researchers said, with more than 50% of the patients enrolled in COVID Watch having been Black or Latino.

“This is important because Black and Hispanic communities have experienced higher exposure and infection rates, decreased access to care, and have had higher mortality rates,” Dr. Delgado said. “Therefore, the results imply that this type of program could play a role in decreasing disparities in COVID outcomes if scaled more broadly.”
 

Outside expert: COVID Watch bring new approach to digital health monitoring

The study not only highlights the efficacy and sustainment of the COVID Watch program, but it sheds light on the possibility of using text message monitoring systems on other chronic disease conditions, said Jamie Faro, PhD, who was not involved in the study.

“It brings a new approach to health monitoring using digital means, which may lessen the burden on health care providers and be more cost effective than usual care approaches,” said Dr. Faro, who is assistant professor at the department of population and quantitative health sciences at the University of Massachusetts, Worcester. “Text messaging, which is used by over 80% of Americans, can allow us to reach a large percentage of the population for remote health care monitoring.”

Researchers of the current study said the findings “reveal a model for outpatient health system management of patients with COVID-19 and possibly other conditions where the early detection of clinical declines is critical.” Dr. Faro said that COVID Watch can have a measurable impact on an outcome that is truly life or death. However, it would be critical to understand how to reach those who either “were not offered or refused to take part in the program.”

The authors of the paper and Dr. Faro had no disclosures.

Background: Though most PEs do not have significant complications, 15% may be associated with risk of death or hemodynamic compromise. Retrospectively derived risk scores are used to risk-stratify patients and guide acute treatment strategies. It is unclear how well existing risk scores estimate mortality outcomes in patients with acute PE.

Patients with idiopathic pulmonary fibrosis (IPF) complete and respond to pulmonary rehabilitation at rates similar to patients with chronic obstructive pulmonary disease (COPD), according to results of a real-world study. The findings reported in an article published in the journal CHEST^® reinforce pulmonary rehabilitation’s benefits for this population.

A progressive decline in respiratory and physical function characterizes IPF, with median survival from diagnosis of 3-5 years, according to Claire Nolan, PhD, of Harefield Hospital, Middlesex, England, and colleagues. The effects of pharmacologic therapies on IPF on symptom burden and quality of life are modest, although lung function decline may be slowed. Supporting evidence for pulmonary rehabilitation benefit in IPF is more modest than it is for COPD, for which exercise capacity, dyspnea, and health-related quality of life improvement have been demonstrated.

“We did not design a randomized, controlled trial,” Dr. Nolan said in an interview, “as it was considered unethical by the local ethics committee to withhold pulmonary rehabilitation based on clinical guidance in the United Kingdom.” She pointed out that initial pulmonary rehabilitation trials in COPD included an intervention (pulmonary rehabilitation) and a control (standard medical care) arm.

The study aims were to compare the effects of pulmonary rehabilitation with real-world data between IPF and COPD with respect to magnitude of effect and survival. The authors’ hypothesis was that IPF patients would have a blunted response to pulmonary rehabilitation with reduced completion rates, compared with a matched COPD group, and with increased mortality.
 

Study details

Investigators use propensity score matching of 163 IPF patients with a control group of 163 patients with COPD referred to pulmonary rehabilitation. Completion rates, responses, and survival status were recorded for 1-year following pulmonary rehabilitation discharge. The 8-week outpatient program was composed of two supervised exercise and education sessions with additional unsupervised home-based exercise each week.

While spirometry data, as expected, showed a higher proportion of IPF patients using supplemental oxygen, pulmonary rehabilitation completion rates were similar for both groups (IPF, 69%; COPD, 63%; P = .24) and there was no between group difference in the number of sessions attended (P = .39). Medical Research Council (muscle strength) (MRC), incremental shuttle walk test (ISW), and Chronic Respiratory Questionnaire total score (CRQ-T) improved significantly in both groups, again with no significant difference between groups.

Over the study course, there was progressive, significant worsening of forced vital capacity percentage, predicted, prescription supplemental oxygen, resting peripheral oxygen saturation, exercise capacity, health-related quality of life and pulmonary rehabilitation adherence across groups of responders (n = 63; 38%), nonresponders (n = 50; 31%) and noncompleters (n = 50; 31%). Among the IPF patients, 6 died before completing pulmonary rehabilitation, with 42 (27%) dying during follow-up.
 

Benefits of rehabilitation

Multivariable analyses showed that noncompletion and nonresponse were associated with significantly higher risk of all-cause mortality at 1-year. Also, time to all-cause mortality was shorter (P = .001) for noncompleters and nonresponders, compared with completers. A trend toward higher completion rates in the IPF group, compared with the COPD group, may be explained, the researchers explained, by fewer hospitalizations over the prior 12 months in the IPF group.

“Although many programs are designed for people with COPD,” Dr. Nolan and colleagues concluded, “our study demonstrates that people with IPF have similar clinical benefits and completion rates to those with COPD. These data reinforce the importance of referral to and engagement in pulmonary rehabilitation amongst the IPF population.”

These findings, Dr. Nolan emphasized, emerged from a single center, and validation in other settings is needed.

Abnormalities in the T-wave morphology of an electrocardiogram (ECG) are classically attributed to ischemic cardiac disease. However, these changes can be seen in a variety of other etiologies, including noncardiac pathology, which should be considered whenever reviewing an ECG: central nervous system disease, including stroke and subarachnoid hemorrhage; hypothermia; pulmonary disease, such as pulmonary embolism or chronic obstructive pulmonary disease; myopericarditis; drug effects; and electrolyte abnormalities.

Prolongation of the QT interval, on the other hand, can be precipitated by medications, metabolic derangements, or genetic phenotypes. The QT interval is measured from the beginning of the QRS complex to the termination of the T wave and represents the total time for ventricular depolarization and repolarization. The QT interval must be corrected based on the patient’s heart rate, known as the QTc. As the QTc interval lengthens, there is increased risk of R-on-T phenomena, which may result in Torsades de Pointes (TdP). Typical features of TdP include an antecedent prolonged QTc, cyclic polymorphic ventricular tachycardia on the surface ECG, and either a short-lived spontaneously terminating course or degeneration into ventricular fibrillation (VF) and sudden cardiac death.¹ These dysrhythmias become more likely as the QTc interval exceeds 500 msec.²

The combination of new-onset global T-wave inversions with prolongation of the QT interval has been reported in only a few limited conditions. Some known causes of these QT T changes include cardiac ischemia, status epilepticus, pheochromocytoma, and acute cocaine intoxication.³ One uncommon and rarely reported cause of extreme QT prolongation and T-wave inversion is acute pulmonary edema. The ECG findings are not present on initial patient presentation; rather the dynamic changes occur after resolution of the pulmonary symptoms. Despite significant ECG changes, all prior reported cases describe ECG normalization without significant morbidity.^4,5 We report a case of extreme QT prolongation following acute pulmonary edema that resulted in cardiac arrest secondary to VF.

Case Presentation

A 72-year-old male with medical history of combined systolic and diastolic heart failure, ischemic cardiomyopathy, coronary artery disease, cerebral vascular accident, hypertension, hyperlipidemia, type 2 diabetes mellitus, and tobacco dependence presented to the emergency department (ED) by emergency medical services after awaking with acute onset of dyspnea and diaphoresis. On arrival at the ED, the patient was noted to be in respiratory distress (ie, unable to speak single words) and was extremely diaphoretic. His initial vital signs included blood pressure, 186/113 mm Hg, heart rate, 104 beats per minute, respiratory rate, 40 breaths per minute, and temperature, 36.4 °C. The patient was quickly placed on bilevel positive airway pressure and given sublingual nitroglycerin followed by transdermal nitroglycerin with a single dose of 40 mg IV furosemide, which improved his respiratory status. A chest X-ray was consistent with pulmonary edema, and his brain natriuretic peptide was 1654 pg/mL. An ECG demonstrated new T-wave inversions, and his troponin increased from 0.04 to 0.24 ng/mL during his ED stay (Figure 1). He was started on a heparin infusion and admitted to the hospital for hypertensive emergency with presumed acute decompensated heart failure and non-ST-elevated myocardial infarction.

Throughout the patient’s first night, the troponin level started to down-trend after peaking at 0.24 ng/mL, and his oxygen requirements decreased allowing transition to nasal cannula. However, his repeat ECGs demonstrated significant T-wave abnormalities, new premature ventricular contractions, bradycardia, and a prolonging QTc interval to 703 msec (Figure 2). At this time, the patient’s electrolytes were normal, specifically a potassium level of 4.4 mEq/L, calcium 8.8 mg/dL, magnesium 2.0 mg/dL, and phosphorus 2.6 mg/dL. Given the worsening ECG changes, a computed tomography scan of his head was ordered to rule out intracranial pathology. While in the scanner, the patient went into pulseless VF, prompting defibrillation with 200 J. In addition, he was given 75 mg IV lidocaine, 2 g IV magnesium, and 1 ampule of both calcium chloride and sodium bicarbonate. With treatment, he had return of spontaneous circulation and was taken promptly to cardiac catheterization. The catheterization showed no significant obstructive coronary artery disease, and no interventions were performed. The patient was transferred to the cardiac intensive care unit for continued care.

During his course in the intensive care unit, the patient’s potassium and magnesium levels were maintained at high-normal levels. The patient was started on a dobutamine infusion to increase his heart rate and attempt to decrease his QTc. The patient also underwent cardiac magnetic resonance imaging (MRI) to evaluate for possible myocarditis, which showed no evidence of acute inflammation. Echocardiogram demonstrated an ejection fraction of 40% and global hypokinesis but no specific regional abnormalities and no change from prior echocardiogram performed 1 year earlier. Over the course of 3 days, his ECG normalized and his QTc shortened to 477 msec. Genetic testing was performed and did not reveal any mutations associated with long QT syndrome. Ultimately, an automated internal cardiac defibrillator (AICD) was placed, and the patient was discharged home.

Over the 2 years since his initial event, the patient has not experienced recurrent VF and his AICD has not fired. The patient continues to have ED presentations for heart-failure symptoms, though he has been stable from an electrophysiologic standpoint and his QTc remains less than 500 msec.

Discussion

Prolongation of the QT interval as a result of deep, global T-wave inversions after resolution of acute pulmonary edema has been minimally reported.^4,5 This phenomenon has been described in the cardiology literature but has not been discussed in the emergency medicine literature and bears consideration in this case.^4,5 As noted, an extensive evaluation did not reveal another cause of QTc prolongation. The patient had normal electrolytes and temperature, his neurologic examination and computed tomography were not remarkable. The patient had no obstructive coronary artery disease on catheterization, no evidence of acute myocarditis on cardiac MRI, no prescribed medications associated with QT prolongation, and no evidence of genetic mutations associated with QT prolongation on testing. The minimal troponin elevation was felt to represent a type II myocardial infarction related to ischemia due to supply-demand mismatch rather than acute plaque rupture.

Littmann published a case series of 9 cases of delayed onset T-wave inversion and extreme QTc prolongation in the 24 to 48 hours following treatment and symptomatic improvement in acute pulmonary edema.⁴ In each of his patients, an ischemic cardiac insult was ruled out as the etiology of the pulmonary edema by laboratory assessment, echocardiography, and left heart catheterization.All of the patients in this case series recovered without incident and with normalization of the QTc interval.⁴ Similarly, in our patient, significant QT T changes occurred approximately 22 hours after presentation and with resolution of symptoms of pulmonary edema. Pascale and colleagues also published a series of 3 patients developing similar ECG patterns following a hypertensive crisis with resolution of ECG findings and without any morbidity.⁵ In contrast, our patient experienced significant morbidity secondary to the extreme QTc prolongation.

Conclusions

We believe this is the first reported case of excessive prolongation of the QTc with VF arrest secondary to resolution of acute pulmonary edema. The pattern observed in our patient follows the patterns outlined in the previous case series—patients present with acute pulmonary edema and hypertensive crisis but develop significant ECG abnormalities about 24 hours after the resolution of the high catecholamine state. Our patient did have a history of prior cardiac insult, given the QTc changes developed acutely, with frequent premature ventricular contractions, and the cardiac arrest occurred at maximal QTc prolongation, yet after resolution of the high catecholamine state, the treatment team felt there was likely an uncaptured and short-lived episode of TdP that degenerated into VF. This theory is further supported by the lack of recurrent VF episodes, confirmed by AICD interrogation, after normalization of the QTc in our patient.

Echocardiogram demonstrated an ejection fraction of 40% and global hypokinesis but no specific regional abnormalities and no change from prior echocardiogram performed 1 year earlier. Over the course of 3 days, his ECG normalized and his QTc shortened to 477 msec. Genetic testing was performed and did not reveal any mutations associated with long QT syndrome. Ultimately, an automated internal cardiac defibrillator (AICD) was placed, and the patient was discharged home.

Over the 2 years since his initial event, the patient has not experienced recurrent VF and his AICD has not fired. The patient continues to have ED presentations for heart-failure symptoms, though he has been stable from an electrophysiologic standpoint and his QTc remains less than 500 msec.

Discussion

Prolongation of the QT interval as a result of deep, global T-wave inversions after resolution of acute pulmonary edema has been minimally reported.^4,5 This phenomenon has been described in the cardiology literature but has not been discussed in the emergency medicine literature and bears consideration in this case.^4,5 As noted, an extensive evaluation did not reveal another cause of QTc prolongation. The patient had normal electrolytes and temperature, his neurologic examination and computed tomography were not remarkable. The patient had no obstructive coronary artery disease on catheterization, no evidence of acute myocarditis on cardiac MRI, no prescribed medications associated with QT prolongation, and no evidence of genetic mutations associated with QT prolongation on testing. The minimal troponin elevation was felt to represent a type II myocardial infarction related to ischemia due to supply-demand mismatch rather than acute plaque rupture.

Littmann published a case series of 9 cases of delayed onset T-wave inversion and extreme QTc prolongation in the 24 to 48 hours following treatment and symptomatic improvement in acute pulmonary edema.⁴ In each of his patients, an ischemic cardiac insult was ruled out as the etiology of the pulmonary edema by laboratory assessment, echocardiography, and left heart catheterization.All of the patients in this case series recovered without incident and with normalization of the QTc interval.⁴ Similarly, in our patient, significant QT T changes occurred approximately 22 hours after presentation and with resolution of symptoms of pulmonary edema. Pascale and colleagues also published a series of 3 patients developing similar ECG patterns following a hypertensive crisis with resolution of ECG findings and without any morbidity.⁵ In contrast, our patient experienced significant morbidity secondary to the extreme QTc prolongation.

Conclusions

We believe this is the first reported case of excessive prolongation of the QTc with VF arrest secondary to resolution of acute pulmonary edema. The pattern observed in our patient follows the patterns outlined in the previous case series—patients present with acute pulmonary edema and hypertensive crisis but develop significant ECG abnormalities about 24 hours after the resolution of the high catecholamine state. Our patient did have a history of prior cardiac insult, given the QTc changes developed acutely, with frequent premature ventricular contractions, and the cardiac arrest occurred at maximal QTc prolongation, yet after resolution of the high catecholamine state, the treatment team felt there was likely an uncaptured and short-lived episode of TdP that degenerated into VF. This theory is further supported by the lack of recurrent VF episodes, confirmed by AICD interrogation, after normalization of the QTc in our patient.

Although genomic testing is useful when an interstitial lung disease diagnosis is uncertain, the testing results themselves aren’t sufficient to make the diagnosis, Daniel Dilling, MD, FCCP, said in a presentation at the annual meeting of the American College of Chest Physicians, which was held virtually.

The genomic classifier (Envisia, Veracyte) helps differentiate idiopathic pulmonary fibrosis (IPF) by detecting usual interstitial pneumonia (UIP), the hallmark pattern of this interstitial lung disease.

However, UIP is just one piece of the larger diagnostic puzzle, according to Dr. Dilling, professor of medicine in the interstitial lung disease program at Loyola University Medical Center in Maywood, Ill.

“Remember, it’s just a pattern, and not a diagnosis of IPF,” Dr. Dilling said in his presentation.

Genomic classifier results correlate well with both histologic and radiographic UIP pattern, studies show.

However, Dr. Dilling said the value of the genomic classifier is not in isolation.

“We don’t use this in a vacuum,” he said. “It increases our confidence and consensus, but it has to be incorporated into a multidisciplinary discussion group.”
 

Part of the diagnostic pathway

Dr. Dilling said the genomic classifier should be considered part of a diagnostic pathway in uncertain cases, particularly when the risk of surgical lung biopsy is high.

Current clinical practice guidelines recommend surgical lung biopsy for histopathologic diagnosis when clinical and radiologic findings are not definitive for IPF, the speaker said.

However, surgical lung biopsy carries some risk, and sometimes it can’t be done, he added.

In his presentation, Dr. Dilling cited a systematic review and meta-analysis of 23 studies looking at surgical lung biopsy for the diagnosis of interstitial lung diseases.

The postoperative mortality rate was 3.6% in that meta-analysis, published in 2015 in the Journal of Thoracic and Cardiovascular Surgery.

“The final decision regarding whether or not to perform a [surgical lung biopsy] must be based on the balance between benefits to establish a secure diagnosis and the potential risks,” authors wrote at the time.

Mortality risk is higher in immunocompromised and acutely ill patient populations, according to Dr. Dilling, who added that as many of 19% of patients will have complications from surgical lung biopsy.
 

Genomic classifier studies

In a proof-of-principle study, published in 2017 in the Annals of the American Thoracic Society, authors described how they used machine learning to train an algorithm to distinguish UIP from non-UIP pattern in tissue obtained by transbronchial biopsy (TBB).

The top-performing algorithm distinguished UIP from non-UIP conditions in single TBB samples with specificity of 86% and sensitivity of 63%, according to investigators, who said at the time that independent validation would be needed before the genomic classifier could be applied in clinical settings.

In a prospective validation study, published in 2019 in The Lancet Respiratory Medicine, the genomic classifier identified UIP in TBB samples from 49 patients with a specificity of 88% and sensitivity of 70%.

Excluding patients with definite or probable UIP as shown on high-resolution computed tomography, results show that the classifier had a sensitivity of 76%, specificity of 88%, and positive predictive value of 81%.

“The performance of the test is good, even in that scenario,” Dr. Dilling said.
 

Real-world results

Dr. Dilling also highlighted a “real-world” study, published earlier in 2021, demonstrating that UIP pattern recognized by a genomic classifier had encouraging sensitivity and specificity when combined with high-resolution CT and clinical factors.

That study included 96 patients who had both diagnostic lung pathology and a transbronchial lung biopsy for molecular testing with the classifier.

The classifier had a sensitivity of 60.3% and a specificity of 92.1% for histology-proven UIP pattern, investigators said in their report, which appears in the American Journal of Respiratory and Critical Care Medicine.

Local radiologists identified UIP with a sensitivity of 34.0% and specificity of 96.9%. But adding genomic classifier testing to local radiology testing increased the diagnostic yield, investigators said, with a sensitivity of 79.2% and specificity of 90.6%.

“This might suggest that the implementation of this into a local [multidisciplinary discussion] with your local radiology expertise might really improve your recognition of UIP,” Dr. Dilling said.

Dr. Dilling reported disclosures related to Bellerophon, Boehringer Ingelheim, Genentech, Nitto Denko, and Lung Bioengineering.

An electronic nose (eNose) that measures volatile organic compounds (VOCs) emitted from the lungs successfully distinguished sarcoidosis from interstitial lung disease (ILD) and healthy controls, according to a report in the journal CHEST.

The approach has the potential to generate clinical data that can’t be achieved through other noninvasive means, such as the serum biomarker soluble interleukin-2 receptor (sIL-2R). sIL-2R is often used to track disease activity, but it isn’t specific for diagnosing sarcoidosis, and it isn’t available worldwide.

Sarcoidosis is a granulomatous inflammatory disease with no known cause and can affect most organs, but an estimated 89%-99% of cases affect the lungs. There is no simple noninvasive diagnostic test, leaving physicians to rely on clinical features, biopsies to obtain tissue pathology, and the ruling out of other granulomatous diagnoses.

The challenge is more difficult because sarcoidosis is a heterogeneous disease, with great variation in the number of organs affected, severity, rate of progression, and response to therapy.

Previous researchers have used VOCs in an attempt to diagnose diseases, since the compounds reflect pathophysiological processes. Gas chromatography/mass spectrometry (GCMS) is one method to identify the individual VOCs, but the process is time consuming and complex. Some nevertheless showed potential in sarcoidosis, but failed to reproduce their performance in validation cohorts.

In the new study, a cross-sectional analysis showed that exhaled breath analysis using an eNose had excellent sensitivity and specificity for distinguishing sarcoidosis from ILD and healthy controls, and identified sarcoidosis regardless of pulmonary involvement, pulmonary fibrosis, multiple organ involvement, immunosuppressive treatment, or whether or not pathology supported the diagnosis.

The eNose technology produces a “breath-print” after combining information from a broad range of VOCs. The information originates from an array of metal-oxide semiconductor sensors with partial specificity that artificial intelligence processes to discern patterns. Overall, the system functions similarly to the mammalian olfactory system. The artificial intelligence instead views it as a “breath-print” that it can compare against previously learned patterns.

“It is a quite easy, simple, and quick procedure, which is noninvasive. We can collect a lot of data from the VOCs in the exhaled breath because there are several sensors that cross-react. We can create breath profiles and group patients to see if profiles differ. Ultimately, we can use the profiles to diagnose or detect disease in the earlier stage and more accurately,” said Iris van der Sar, MD. Dr. van der Sar is the lead author on the study and a PhD candidate at Erasmus Medical Center in Rotterdam.

The study requires further prospective validation, but the technology could have important clinical benefits, said senior author and principal investigator Marlies Wijsenbeek, MD, PhD, pulmonologist and head of the Interstitial Lung Disease Center at Erasmus Medical Center. “If we in future can avoid a biopsy, that would be most attractive,” said Dr. Wijsenbeek.

“We hope to come to a point-of-care device that can be used to facilitate early diagnosis at low burden for the patient and health care system,” said Karen Moor, MD, PhD, and post-doc on this project. The researchers also hope to determine if the eNose can help evaluate a patient’s response to therapy.

Studies of eNose technology in other chronic diseases have shown promising results, but not all results have been validated yet in independent or external cohorts.

The current study included 569 outpatients, 252 with sarcoidosis and 317 with ILD, along with 48 healthy controls. The researchers constructed a training set using 168 patients with sarcoidosis and 32 healthy controls, and a validation set using 84 patients with sarcoidosis and 16 healthy controls. The eNose differentiated between patients and controls in both groups, with an area under the curve of 1.00 for each regardless of pulmonary involvement or treatment.

It also distinguished those with sarcoidosis and pulmonary involvement from those with ILD, with an AUC of 0.90 (95% confidence interval, 0.87-0.94) in the training set, and an AUC of 0.87 (95% CI, 0.82-0.93) in the validation set.

It differentiated between pulmonary sarcoidosis and hypersensitivity pneumonitis in the training set (AUC 0.95; 95% CI, 0.90-0.99) and the validation set (AUC, 0.88; 95% CI, 0.75-1.00).

The study received no funding. Dr. Wijsenbeek, Dr. van der Sar, and Dr. Moor have no relevant financial disclosures.

Increased mental health needs, higher acuity from delayed appointments, and added questions and conversations surrounding COVID-19 are forcing primary care offices to rethink priorities in office visits.

Evidence of this came from the latest Primary Care Collaborative (PCC) survey, which found that primary care clinicians are seeing more complex patients requiring longer appointments in the wake of COVID-19.

The PCC with the Larry A. Green Center regularly surveys primary care clinicians. This round of questions came August 14-17 and included 1,263 respondents from 49 states, the District of Columbia, and two territories.

More than 7 in 10 (71%) respondents said their patients are more complex and nearly the same percentage said appointments are taking more time.

Ann Greiner, president and CEO of the PCC, said in an interview that 55% of respondents reported that clinicians are struggling to keep up with pent-up demand after patients have delayed or canceled care. Sixty-five percent in the survey said they had seen a rise in children’s mental health issues, and 58% said they were unsure how to help their patients with long COVID.

In addition, primary care clinicians are having repeated conversations with patients on why they should get a vaccine and which one.

“I think that’s adding to the complexity. There is a lot going on here with patient trust,” Ms. Greiner said.
 

‘We’re going to be playing catch-up’

Jacqueline Fincher, MD, an internist in Thompson, Ga., said in an interview that appointments have gotten longer and more complex in the wake of the pandemic – “no question.”

The immediate past president of the American College of Physicians is seeing patients with chronic disease that has gone untreated for sometimes a year or more, she said.

“Their blood pressure was not under good control, they were under more stress, their sugars were up and weren’t being followed as closely for conditions such as congestive heart failure,” she said.

Dr. Fincher, who works in a rural practice 40 miles from Augusta, Ga., with her physician husband and two other physicians, said patients are ready to come back in, “but I don’t have enough slots for them.”

She said she prioritizes what to help patients with first and schedules the next tier for the next appointment, but added, “honestly, over the next 2 years we’re going to be playing catch-up.”

At the same time, the CDC has estimated that 45% of U.S. adults are at increased risk for complications from COVID-19 because of cardiovascular disease, diabetes, respiratory disease, hypertension, or cancer. Rates ranged from 19.8% for people 18-29 years old to 80.7% for people over 80 years of age.
 

Long COVID could overwhelm existing health care capacity

Primary care physicians are also having to diagnose sometimes “invisible” symptoms after people have recovered from acute COVID-19 infection. Diagnosing takes intent listening to patients who describe symptoms that tests can’t confirm.

As this news organization has previously reported, half of COVID-19 survivors report postacute sequelae of COVID-19 (PASC) lasting longer than 6 months.

“These long-term PASC effects occur on a scale that could overwhelm existing health care capacity, particularly in low- and middle-income countries,” the authors wrote.
 

Anxiety, depression ‘have gone off the charts’

Danielle Loeb, MD, MPH, associate professor of internal medicine at the University of Colorado in Denver, who studies complexity in primary care, said in the wake of COVID-19, more patients have developed “new, serious anxiety.”

“That got extremely exacerbated during the pandemic. Anxiety and depression have gone off the charts,” said Dr. Loeb, who prefers the pronoun “they.”

Dr. Loeb cares for a large number of transgender patients. As offices reopen, some patients are having trouble reintegrating into the workplace and resuming social contacts. The primary care doctor says appointments can get longer because of the need to complete tasks, such as filling out forms for Family Medical Leave Act for those not yet ready to return to work.

COVID-19–related fears are keeping many patients from coming into the office, Dr. Loeb said, either from fear of exposure or because they have mental health issues that keep them from feeling safe leaving the house.

“That really affects my ability to care for them,” they said.

Loss of employment in the pandemic or fear of job loss and subsequent changing of insurance has complicated primary care in terms of treatment and administrative tasks, according to Dr. Loeb.

To help treat patients with acute mental health issues and manage other patients, Dr. Loeb’s practice has brought in a social worker and a therapist.

Team-based care is key in the survival of primary care practices, though providing that is difficult in the smaller clinics because of the critical mass of patients needed to make it viable, they said.

“It’s the only answer. It’s the only way you don’t drown,” Dr. Loeb added. “I’m not drowning, and I credit that to my clinic having the help to support the mental health piece of things.”
 

Rethinking workflow

Tricia McGinnis, MPP, MPH, executive vice president of the nonprofit Center for Health Care Strategies (CHCS) says complexity has forced rethinking workflow.

“A lot of the trends we’re seeing in primary care were there pre-COVID, but COVID has exacerbated those trends,” she said in an interview.

“The good news ... is that it was already becoming clear that primary care needed to provide basic mental health services and integrate with behavioral health. It had also become clear that effective primary care needed to address social issues that keep patients from accessing health care,” she said.

Expanding care teams, as Dr. Loeb mentioned, is a key strategy, according to Ms. McGinnis. Potential teams would include the clinical staff, but also social workers and community health workers – people who come from the community primary care is serving who can help build trust with patients and connect the patient to the primary care team.

“There’s a lot that needs to happen that the clinician doesn’t need to do,” she said.

Telehealth can be a big factor in coordinating the team, Ms. McGinnis added.

“It’s thinking less about who’s doing the work, but more about the work that needs to be done to keep people healthy. Then let’s think about the type of workers best suited to perform those tasks,” she said.

As for reimbursing more complex care, population-based, up-front capitated payments linked to high-quality care and better outcomes will need to replace fee-for-service models, according to Ms. McGinnis.

That will provide reliable incomes for primary care offices, but also flexibility in how each patient with different levels of complexity is managed, she said.

Ms. Greiner, Dr. Fincher, Dr. Loeb, and Ms. McGinnis have no relevant financial relationships.

Increased mental health needs, higher acuity from delayed appointments, and added questions and conversations surrounding COVID-19 are forcing primary care offices to rethink priorities in office visits.

Evidence of this came from the latest Primary Care Collaborative (PCC) survey, which found that primary care clinicians are seeing more complex patients requiring longer appointments in the wake of COVID-19.

The PCC with the Larry A. Green Center regularly surveys primary care clinicians. This round of questions came August 14-17 and included 1,263 respondents from 49 states, the District of Columbia, and two territories.

More than 7 in 10 (71%) respondents said their patients are more complex and nearly the same percentage said appointments are taking more time.

Ann Greiner, president and CEO of the PCC, said in an interview that 55% of respondents reported that clinicians are struggling to keep up with pent-up demand after patients have delayed or canceled care. Sixty-five percent in the survey said they had seen a rise in children’s mental health issues, and 58% said they were unsure how to help their patients with long COVID.

In addition, primary care clinicians are having repeated conversations with patients on why they should get a vaccine and which one.

“I think that’s adding to the complexity. There is a lot going on here with patient trust,” Ms. Greiner said.
 

‘We’re going to be playing catch-up’

Jacqueline Fincher, MD, an internist in Thompson, Ga., said in an interview that appointments have gotten longer and more complex in the wake of the pandemic – “no question.”

The immediate past president of the American College of Physicians is seeing patients with chronic disease that has gone untreated for sometimes a year or more, she said.

“Their blood pressure was not under good control, they were under more stress, their sugars were up and weren’t being followed as closely for conditions such as congestive heart failure,” she said.

Dr. Fincher, who works in a rural practice 40 miles from Augusta, Ga., with her physician husband and two other physicians, said patients are ready to come back in, “but I don’t have enough slots for them.”

She said she prioritizes what to help patients with first and schedules the next tier for the next appointment, but added, “honestly, over the next 2 years we’re going to be playing catch-up.”

At the same time, the CDC has estimated that 45% of U.S. adults are at increased risk for complications from COVID-19 because of cardiovascular disease, diabetes, respiratory disease, hypertension, or cancer. Rates ranged from 19.8% for people 18-29 years old to 80.7% for people over 80 years of age.
 

Long COVID could overwhelm existing health care capacity

Primary care physicians are also having to diagnose sometimes “invisible” symptoms after people have recovered from acute COVID-19 infection. Diagnosing takes intent listening to patients who describe symptoms that tests can’t confirm.

As this news organization has previously reported, half of COVID-19 survivors report postacute sequelae of COVID-19 (PASC) lasting longer than 6 months.

“These long-term PASC effects occur on a scale that could overwhelm existing health care capacity, particularly in low- and middle-income countries,” the authors wrote.
 

Anxiety, depression ‘have gone off the charts’

“That got extremely exacerbated during the pandemic. Anxiety and depression have gone off the charts,” said Dr. Loeb, who prefers the pronoun “they.”

Dr. Loeb cares for a large number of transgender patients. As offices reopen, some patients are having trouble reintegrating into the workplace and resuming social contacts. The primary care doctor says appointments can get longer because of the need to complete tasks, such as filling out forms for Family Medical Leave Act for those not yet ready to return to work.

COVID-19–related fears are keeping many patients from coming into the office, Dr. Loeb said, either from fear of exposure or because they have mental health issues that keep them from feeling safe leaving the house.

“That really affects my ability to care for them,” they said.

Loss of employment in the pandemic or fear of job loss and subsequent changing of insurance has complicated primary care in terms of treatment and administrative tasks, according to Dr. Loeb.

To help treat patients with acute mental health issues and manage other patients, Dr. Loeb’s practice has brought in a social worker and a therapist.

Team-based care is key in the survival of primary care practices, though providing that is difficult in the smaller clinics because of the critical mass of patients needed to make it viable, they said.

“It’s the only answer. It’s the only way you don’t drown,” Dr. Loeb added. “I’m not drowning, and I credit that to my clinic having the help to support the mental health piece of things.”
 

Rethinking workflow

Tricia McGinnis, MPP, MPH, executive vice president of the nonprofit Center for Health Care Strategies (CHCS) says complexity has forced rethinking workflow.

“A lot of the trends we’re seeing in primary care were there pre-COVID, but COVID has exacerbated those trends,” she said in an interview.

“The good news ... is that it was already becoming clear that primary care needed to provide basic mental health services and integrate with behavioral health.
