  • Acute Respiratory Failure Associated With Vaping
    • Authors: Craig Fryman; Becky Lou, Andrew G. Weber, Harry N. Steinberg, Sameer Khanijo, Annamaria Iakovou, Mina R. Makaryus
      Abstract: The use of e-cigarettes to deliver aerosolized nicotine has gained popularity in recent years. Numerous reports have cited the development of acute pulmonary disease linked to vaping nicotine as well as marijuana-based products. As cultural attitudes evolve and policies shift toward the legalization of marijuana, its use has become more prevalent. Given the increased prevalence of marijuana consumption and e-cigarette usage, better insight into its potential to cause lung toxicity is warranted. The clinical, radiographic, and histopathologic characteristics of lung injury associated with vaping, particularly with marijuana-based products, have yet to be well described in the literature.

  • An 80-Year-Old Woman With a Solitary Pulmonary Nodule
    • Authors: Jean-Baptiste Gibier; Magali Colombat, Nathalie Grardel, Marie de Charette, Ophélie Ouennoure, Rias Akkad, Marie-Christine Copin
      Abstract: An 80-year-old-woman was referred for evaluation of chest pain that appeared after providing care at home for her sick husband, which included helping him to get up and move about. The pain was initially triggered by lifting heavy objects but then became constant, without exacerbating or relieving factors. The pain was located in the left hemithorax and was not associated with shortness of breath or cough. Because the patient did not feel any better after a month, her general practitioner ordered a radiograph, which revealed a suspicious pulmonary nodule in the left upper lobe.

    • Authors: Bruce F. Sabath; Samiha Khan
      Abstract: A 54-year-old woman with a history of alcoholic cirrhosis and recurrent ascites presented to the ED with 1 day of abdominal pain and increasing abdominal girth. She had undergone therapeutic paracentesis (5 L removed) the day prior but later noted that her fluid seemed to be reaccumulating. BP at presentation was 87/57 mm Hg, and her hemoglobin level was 6.5 g/dL; just prior to paracentesis the day before, these values had been 120/40 mm Hg and 8.6 g/dL, respectively. She also complained of lightheadedness.

  • A 78-Year-Old Man With Recurrent Hemoptysis and Persistent Pulmonary
    • Authors: Si Yuan Chew; Chien Sheng Tan, Youxin Puan, Jansen Meng Kwang Koh
      Abstract: A 78-year-old Chinese man presented in March 2019 with a 2-day history of small-volume hemoptysis. He did not report any associated chronic cough, sputum production, epistaxis, night sweats, unintentional weight loss, or fever. He was an ex-smoker of 10 pack years. His medical history was significant for ischemic heart disease on aspirin, as well as hospitalizations in 2016 and 2017 for hemoptysis. The patient’s evaluation for hemoptysis was only notable for a right middle lobe nodule on chest CT imaging and Klebsiella pneumoniae on sputum cultures, for which he was treated with antibiotics.

    • Authors: Bryan D. Park; Kenneth Lyn-Kew, Ann Granchelli, Anuj Mehta
      Abstract: A 62-year-old woman with a history of partially treated Graves disease and hypertension presented with approximately 3 weeks of worsening fatigue, lower extremity myalgias, and shortness of breath. Her medical history included a thyroid radiofrequency ablation several years earlier. Following the ablation, she was found to have some residual thyroid activity, negating the need for therapy. She was lost to follow-up after months of normal thyroid-stimulating hormone values. On this presentation, the patient was noted to be in atrial fibrillation with a rapid ventricular rate, and although she presented alert and oriented initially, she developed progressive inattentiveness and confusion while in the ED.

  • A Man in His 30s Presenting With Shortness of Breath and Productive Cough
           After a Recent Pneumonia
    • Authors: Haris Patail; Hassan Patail, Sahar Ahmad
      Abstract: A man in his 30s with a history of substance abuse, including opioids and tobacco, presented to the ED with cough productive of yellow sputum, shortness of breath, chills, and diaphoresis. Vital signs were significant for a BP of 106/65 mm Hg; other vital signs were normal. CBC analysis showed no leukocytosis, hemoglobin of 8.9 g/dL, and an elevated platelet count of 388 mL3. A month before presentation, the patient underwent right-sided thoracentesis at an outside hospital and was treated for pneumonia with antibiotics.

  • Bruxism Relieved Under CPAP Treatment in a Patient With OSA Syndrome
    • Authors: Jean-Benoit Martinot; Jean-Christian Borel, Nhat-Nam Le-Dong, Philip E. Silkoff, Stephane Denison, David Gozal, Jean-Louis Pépin
      Abstract: Bruxism is a heterogeneous condition related to various underlying mechanisms, including the presence of OSA. This case report illustrates that sleep mandibular movement monitoring and analysis could provide a useful opportunity for detection of both sleep bruxism and respiratory effort. The current case suggests that tracking of respiratory effort could enable evaluation of bruxism and its potential interactions. Successful treatment of sleep-related respiratory effort may lead to improved or resolution of bruxism in cases where such a causal relationship does exist.

  • Bronchial Thermoplasty
    • Authors: Geoffrey Lowell Chupp
      Pages: 479 - 480
      Abstract: In 2010, for the first time, the Federal Drug Agency approved bronchial thermoplasty (BT), a nonpharmacologic treatment for severe uncontrolled asthma. Indicated for disease that remains uncontrolled despite adherent use of high-dose inhaled corticosteroids and long-acting bronchodilators, BT is believed to work by applying radiofrequency energy via a catheter placed through a bronchoscope to airways between 3 and 10 mm in diameter. This action generates heat in the airway wall that preferentially injures smooth muscle cells, which fail to heal and regrow, reducing the muscle mass around the airway.

  • Predicting COPD and Lung Function Decline Among a General Population
    • Authors: Valerie G. Press; Andrea Gershon, Denitza P. Blagev
      Pages: 481 - 483
      Abstract: Diagnosing COPD is an important public health priority. Currently, COPD is diagnosed through a combination of clinical symptoms and physiological measurements via pulmonary function tests (PFTs). However, “clinical” diagnoses of COPD are frequently made without the use of PFTs.1-3 Furthermore, because COPD is believed to be drastically underdiagnosed,1 effective tools to screen for risk of COPD among a general population are needed.4 However, screening for COPD using PFTs or questionnaires is not recommended by current guidelines due to a dearth of data regarding the efficacy of these tools for improving outcomes.

      Abstract: The United Kingdom has the highest prevalence of opioid use disorder (OUD) in Europe with approximately 150,000 people currently receiving treatment for dependent opioid use.1 Since the 1980s, a unified harm minimization approach, which targets the high mortality and morbidity associated with injected opioids, has led to the promotion of the inhaled use of heroin as an alternative to injection.2

  • Oxygen Targets for Patients Who Are Critically Ill

      Abstract: With roots dating back to the 18th century, supplemental oxygen is one of medicine’s most common and fundamental therapies. However, despite generations of doctors using oxygen to treat hundreds of millions of patients, our understanding of how to use oxygen most effectively remains incomplete.

      Abstract: “The Horse in Motion” is a series of photographs taken by Eadweard Muybridge in the 1870s depicting a horse in full gallop.1 Muybridge, a photographer hired by the former governor of California and horse racing enthusiast Leland Stanford, used an array of 12 cameras to capture sequential images of the animal to prove Stanford’s theory that all four of a horse’s feet were briefly off the ground during full gallop, a fact that was not discernible to the human eye alone. Subsequent improvements in both capturing and viewing “motion pictures” helped to launch the cultural phenomenon embodied by modern-day Hollywood but also had important implications in science and medicine.

  • Catheter-Directed Thrombolysis With Ultrasound Assistance for Acute
           Pulmonary Embolism
    • Authors: Srinath Adusumalli; Bram Geller, Jay Giri
      Pages: 491 - 492
      Abstract: Acute pulmonary embolism (PE) is the third leading cause of cardiovascular mortality in the United States after myocardial infarction and stroke.1-4 Accordingly, over the last decade, there has been an increasing focus on in-hospital and ambulatory treatment of PE. Specifically, novel multidisciplinary efforts such as Pulmonary Embolism Response Teams have proliferated throughout many tertiary and quaternary care institutions across the country and are focused on optimizing the care of patients presenting with intermediate and high-risk PE.

  • Utilization of Claims Data in Research
    • Authors: Jed A. Gorden; Candice L. Wilshire, Christopher R. Gilbert
      Pages: 493 - 495
      Abstract: In this issue of CHEST, Verdial et al1 compare safety and cost between the two most commonly used mediastinal diagnostic and staging tools: endobronchial ultrasound (EBUS) and mediastinoscopy. They used MarketScan, a claims database that captures both inpatient and outpatient claims data for individuals with employer-provided commercial insurance. The sample size is large, with 30,570 patients undergoing mediastinal lymph node sampling for any reason. The overall findings of increased safety of EBUS and decreased procedural cost over mediastinoscopy are methodologically sound and consistent with prior published data.

    • Authors: James M. Walter; Lewis Satterwhite, Kenneth E. Lyn-Kew
      Pages: 496 - 498
      Abstract: Point-of-care ultrasound (POCUS) refers to the use of ultrasound by a bedside clinician to guide patient management in real time.1 There is growing consensus that POCUS is an essential tool for clinicians caring for acutely ill patients. Indeed, the integration of POCUS into routine care in the ICU is now widely viewed as standard of care.2

      Abstract: We read with interest the Con argument presented by Dr Kruser and colleagues1 and appreciate the opportunity to respond. We would like to begin by emphasizing shared beliefs: (1) point-of-care ultrasound (POCUS) is a learnable skill. With the appropriate training infrastructure, pulmonary and critical care medicine (PCCM) providers can readily achieve competency. (2) POCUS can and should be incorporated into the care of acutely ill patients. (3) The goal of the critical care community should be to safely accelerate the dissemination of POCUS.

      Abstract: We thank our colleagues for presenting their case in support of hospital-regulated privileges to govern the use of point-of-care ultrasound (POCUS) by intensivists.1 Although we agree with several of their claims, their conclusion in favor of hospital privileging contains a misstep of logic along with a failure to fully anticipate the unfavorable consequences of POCUS regulation.

  • Going Beyond “Bio-markers,” Think “Life-markers”
    • Authors: Laren Tan; Geoff Chupp, Mario Castro, Monica Kraft
      Pages: 503 - 505
      Abstract: As the number of biologics for the treatment of moderate to severe asthma continues to grow, the dilemma of trying to choose the right biologic for the right patient is often heavily weighted on specific biomarkers. At present, biomarker cutoffs provide more options in biologic choice, and the need for shared decision-making (SDM) between patients and health-care providers is necessary to achieve a completely personalized treatment plan. In a survey of 300 patients who attended an allergy clinic, 53% indicated they had searched online for information on allergy prior to their consultation.

  • Severe Acute Toxicity of Inhaled Nicotine and e-Cigarettes
    • Authors: Xuesi M. Shao; Zhuang T. Fang
      Pages: 506 - 508
      Abstract: A recent statement from the US Food and Drug Administration (FDA)1 expresses concern regarding a potential safety issue related to seizures reported following e-cigarette use, particularly in youth and young adults. Since the publication of this statement in April 2019, the FDA announced an update on August 7, 2019, stating that the FDA continues to receive more reports of seizure cases (total 127) following e-cigarette use. This number is probably an underestimation due to the voluntary nature of the reports.

      First page: 737
      Abstract: The publication by Alshabani et al1 in CHEST (September 2019) entitled “Broncholithiasis. A review” provides a concise and well-researched review of a clinical scenario that on occasion presents to most pulmonologists and bronchoscopists. It is notable that the authors list one of the chronic airway disorders, primary ciliary dyskinesia (PCD), as a cause of broncholithiasis, based on a single case report.2 However, this association was first highlighted in our previous publication of a large series of patients with PCD (N = 142) that included 28 patients aged ≥ 40 years, of whom 11 (40%) had calcification on CT imaging and five reported lithoptysis.

      First page: 738
      Abstract: In 2008, the US National Heart, Lung, and Blood Institute task force highlighted the need to reduce, through population screening, the growing health burden attributable to COPD.1 Commendably, Chen et al,2 in this issue of CHEST, have responded to this clinical need by developing, validating, and implementing a personalized risk model to predict the risk of airflow obstruction and 20-year FEV1 trajectory for an individual from the general population. This model was developed using the Framingham offspring cohort (n = 4,167) and validated in almost 15,000 individuals from two other cardiovascular cohorts, although the larger had spirometry measured only over a 3-year period.

      Abstract: We agree with many points made by Perret et al and offer several additional analyses to enhance clarity.1 We agree on the need to provide 95% CIs for the area under the receiver operating characteristic curve (AUC-ROC, also known as the C-statistic). For the derivation cohort, the C-statistic was 0.762 (95% CI, 0.746-0.778), for validation cohort 1 it was 0.864 (95% CI, 0.850-0.882), and for validation cohort 2 it was 0.872 (95% CI, 0.856-0.887). In line with previous findings that the rate of lung function decline generally accelerates over time,2,3 our prediction models captured both the linear and quadratic decline in absolute FEV1.

  • Should the Stethoscope Auscultation Be Routine Practice in the Evaluation
           of the Acutely Breathless Patient' No
    • Authors: Roberto Copetti; Luigi Vetrugno, Daniele Orso, Tiziana Bove
      Pages: 740 - 742
      Abstract: In a faraway hospital, a patient with strong dyspnea is brought to the ED. The patient is elderly, has suffered from an acute myocardial infarction in the past, is hypertensive, has recurrent heart failure episodes, is a heavy smoker, and has COPD. His performance is very poor, so he is very often bedridden. The physicians are uncertain about which diagnosis is most likely. Fortunately, one of the physicians has a newly invented tool. It allows him to hear the patient's chest, and on the basis of perceived different sounds, it is possible to establish, with reasonable probability, the diagnosis: he called it a “stethoscope.” The physician is about to approach the patient with this new instrument, but another physician stops him: “No! Does this instrument have strong evidence of its usefulness'”

      Abstract: We would like to thank our colleagues for their interest in and observations regarding the recent Point-Counterpoint debate1,2 around point-of-care ultrasound (POCUS) in the acutely breathless patient. We readily acknowledge the potential that POCUS has to improve clinical care in this often complex and vulnerable population; indeed, this belief is reflected in our own individual clinical and academic practice. However, just like our colleagues and many others who have published in and sought to advance this particular field, we practice from a privileged position in terms of our relative individual experience and expertise both as clinicians and sonographers.

      Abstract: Chronic Obstructive Pulmonary Disease (COPD) is the second most common cause of hospital admission in the United States. Obstructive sleep apnea (OSA) is a highly prevalent and underdiagnosed condition which may impact the outcome of COPD. We hypothesized that presence of unrecognized and untreated OSA will increase hospital readmissions in patients admitted for COPD exacerbation.

      Abstract: Restless legs syndrome (RLS), also known as Willis-Ekbom disease (WED), is a common neurological disorder affecting up to 5-10% of the population, but it still remains an underdiagnosed condition. RLS/WED is characterized by uncomfortable sensations, mainly in the legs, which appear during inactivity and worsen in the evening or at night. The prevalence of RLS/WED and periodic leg movements (PLMs) is increased in sleep-disordered-breathing patients, particularly in those with obstructive sleep apnoea (OSA), the most common sleep disorder encountered in sleep centres.

      Abstract: Owing to advanced respiratory disease among lung transplant (LTX) candidates, some could develop nontuberculous mycobacteria-pulmonary disease (NTM-PD). However, the appropriate management of NTM-PD found at the time of LTX is not clear. We, therefore, established a management protocol for peri-transplant NTM-PD, defined by the presence of granulomas and mycobacteriologic evidence of NTM in the explant. Between 2013 and 2014, 230 LTX recipients (LTRs) who survived>30 days post LTX were followed up to 2017.

      Abstract: As of March 24, 2020, novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been responsible for 379,661 infection cases with 16,428 deaths globally and the number is still increasing rapidly. Herein, we presented four critically ill patients with SARS-CoV-2 infection who received supportive care and convalescent plasma. Although all the four patients (including a pregnant woman) recovered from SARS-CoV-2 infection eventually, randomized trials are needed to eliminate the effect of other treatments and investigate the safety and efficacy of convalescent plasma therapy.

    • Authors: Aparna Balasubramanian; Todd M. Kolb, Rachel L. Damico, Paul M. Hassoun, Meredith C. McCormack, Stephen C. Mathai
      Abstract: Among patients with COPD-PH, severe gas transfer impairment is associated with higher mortality, even when adjusting for airflow obstruction and hemodynamics, suggesting that DLCO may be a useful prognostic marker in this population. Future studies are needed to further investigate the association between DLCO and morbidity, and to determine the utility of DLCO as a biomarker for disease risk and severity in COPD-PH.

    • Authors: Patrícia Rebelo; Ana Oliveira, Lília Andrade, Carla Valente, Alda Marques
      Abstract: Fatigue is a burdensome and prevailing symptom in patients with chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation (PR) improves fatigue however, interpreting when such improvement is clinically relevant is challenging. Minimal clinically important differences (MCIDs) for instruments assessing fatigue are warranted to better tailor PR and guide clinical decisions. We estimated MCIDs for the functional assessment of chronic illness therapy-fatigue subscale (FACIT-FS), the modified-FACIT-FS and the checklist of individual strength-fatigue subscale (CIS-FS), in patients with COPD after PR.

  • Update on Persistent Excessive Daytime Sleepiness in Obstructive Sleep
    • Authors: Sogol Javaheri; Shahrokh Javaheri
      Abstract: Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder and subjective excessive daytime sleepiness (EDS) is the cardinal symptom for which many individuals seek medical advice. Positive airway pressure (PAP) devices, first line treatment for OSA, eliminates EDS in most patients. However, a subset of patients suffers from persistent EDS despite adherence to therapy. Multiple conditions, some reversible, could account for the residual sleepiness and need to be explored requiring detailed history, review of PAP data from the smart card and sometimes additional testing.

    • Authors: John H. Newman
      Abstract: A physiological approach to the analysis of hemodynamic data in pulmonary hypertension (PH) has the advantage of reducing the large number (well over 100) of potential causal illnesses into four simple mechanisms. A fifth condition is composed of mixtures of the four basic mechanisms. This approach was beautifully described by Paul Wood, the great cardiologist whose name is given to the units of pulmonary vascular resistance (PVR), Wood units. This approach uses well understood physiological contributions to pulmonary vascular pressure.

      Abstract: Interventional pulmonology programs provide clinical benefit to patients and are financially sustainable. In order to appreciate and illustrate the economic value of interventional pulmonology programs to hospital systems, physicians must have an understanding of basic healthcare finance. Total revenue, adjusted gross revenue, contribution margin, variable direct costs, and indirect costs are terms that are essential for understanding the finances of bronchoscopy. Command of such vocabulary and its application is crucial for interventional pulmonologists to successfully establish financially sustainable bronchoscopy programs.

      Abstract: Diuretics have been reported as effective for reducing obstructive sleep apnea (OSA) severity by preventing fluid retention and reducing rostral fluid shift. The benefit of diuretics might vary depending upon the OSA clinical phenotype and comorbidities. To test this hypothesis, we conducted a propensity score-matched cohort analysis of data from the French national sleep apnea registry “Observatoire Sommeil de la Fédération de Pneumologie” (OSFP).

      Abstract: DNA methylation and gene expression are promising biomarkers of various cancers, including non-small cell lung cancer (NSCLC). Besides main effects of biomarkers, the progression of complex diseases is also influenced by gene-gene (GxG) interactions. Screening the functional capacity of biomarkers based on main effects or interactions using multi-omics data may improve the accuracy of cancer prognosis.

      Abstract: Pulmonary arterial hypertension (PAH) is characterized by elevated pulmonary arterial pressures managed by vasodilator therapies. Current guidelines encourage PAH management in specialty care centers (SCCs), but evidence is sparse regarding improvement in clinical outcomes and correlation to vasodilator use with referral. We hypothesize that PAH management at SCCs is associated with improved clinical outcomes.

Of the fILDs, Idiopathic Pulmonary Fibrosis (IPF) is the most common. Pulmonary hypertension (PH) frequently complicates fILD and is associated with impaired functional capability, lower physical activity and significantly reduced life expectancy. There is no proven treatment for patients with fILD-PH. We report results from the first Cohort of a Phase 2b/3 trial with pulsed iNO in patients with fILD-PH.

      Abstract: Ultrasound studies to detect DVT are traditionally performed and interpreted by sonographers and radiologists, respectively, but the growth of point-of-care ultrasound is putting this powerful tool in the hands of front-line physicians. Literature from ambulatory patients in the ED suggests this tool performs well in the hands of nonconventional users, and it is now being commonly deployed to aid in the management of critically ill patients. This article presents an approach for incorporating these tools into bedside practice, including illustrative figures and narrated video presentations to demonstrate the techniques described.

Because the early cases were linked to the Huanan Seafood Market, the market was shut down on January 1, 2020. One week later, on January 7, 2020, Chinese health authorities confirmed that they had identified a novel coronavirus (COVID-19). On January 30, 2020, the World Health Organization Director-General made the final decision on the determination of a Public Health Emergency of International Concern regarding the outbreak in China, with exportations to other countries.

This change has potential to enhance education, clinical documentation quality, and the satisfaction of students, post-graduate trainees, and teaching physicians. However, its practical adoption presents many challenges that must be navigated successfully to realize these important goals in compliance with federal and local requirements, while avoiding unintended downstream problems.

      Abstract: Providing guideline-concordant management of pulmonary nodules can present challenges when a patient’s anxiety about cancer or fear of invasive procedures colors judgment. The way in which providers discuss and make decisions about how to evaluate a pulmonary nodule can affect patient satisfaction, distress, and adherence to evaluation. This article discusses the complexity of tailoring patient-provider communication, decision-making, and implementation of guidelines for pulmonary nodule evaluation to the individual patient, emphasizing the importance of how information is conveyed and the value of listening to and addressing patients’ concerns.

      Abstract: Pulmonary capillary stress failure is potentially involved in exercise-induced hypoxemia (ie, a significant fall in hemoglobin oxygen saturation [Spo2]) during sea level exercise in endurance-trained athletes. It is unknown whether there are specific properties of pulmonary vascular function in athletes exhibiting oxygen desaturation.

      Abstract: Transbronchial lung biopsies are commonly performed for a variety of indications. Although generally well tolerated, complications such as bleeding do occur. Description of bleeding severity is crucial both clinically and in research trials; to date, there is no validated scale that is widely accepted for this purpose. Can a simple, reproducible tool for categorizing the severity of bleeding after transbronchial biopsy be created'

  • Drowning Classification
    • Authors: Thibaut Markarian; Anderson Loundou, Vera Heyer, Cyril Marimoutou, Laurie Borghese, Mathieu Coulange, Pierre Michelet
      Abstract: Drowning is still a major cause of accidental death worldwide. In 1997, Szpilman proposed a classification of drowning that has become the reference. As considerable efforts have been made to improve prevention and care, it seemed appropriate to reassess the prognosis and clinical presentation of drowning patients more than 20 years after this first publication. The aim of this study is to provide a reappraisal of patients who need advanced health care and a precise description of their respective neurologic, respiratory, and hemodynamic profiles.

           Interstitial Lung Disease
    • Authors: Renea Jablonski; Sangeeta Bhorade, Mary E. Strek, Jane Dematte
      Abstract: Idiopathic inflammatory myopathies are autoimmune processes that are characterized by skeletal muscle inflammation. The lung is the most commonly involved extramuscular organ, and, when present, pulmonary disease drives morbidity and mortality. A subset of patients can present with rapidly progressive hypoxemic respiratory failure due to myositis-related interstitial lung disease. Confirmatory autoantibody testing requires sending samples to a reference laboratory; thus, diagnosis of rapidly progressive myositis-associated interstitial lung disease relies on a high index of suspicion and careful history and physical examination.

           Nervous Lesions
    • Authors: Eva Svanborg; Martin Ulander, Anders Broström, Ola Sunnergren
      Abstract: Signs of both motor and sensory nervous lesions have previously been shown in the upper airway of patients with OSA and habitual snorers. Snoring per se may damage all upper airway neurons over time, thereby causing progression to manifest sleep apnea. To test this hypothesis, nonsnoring subjects, untreated snorers, and CPAP-treated patients underwent repeated sensory testing of the soft palate in a prospective long-term study.

      Abstract: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare lung disease associated with proliferation of neuroendocrine cells in the lung and multifocal neuroendocrine tumorlets/tumors. Although usually considered an indolent condition, DIPNECH causes chronic, progressive cough and dyspnea which can adversely impact quality of life. There is very limited information on the treatment of this condition. The objective of this study was to assess changes in symptoms and pulmonary function tests (PFTs) in response to somatostatin analog (SSA) treatment.

      Abstract: Guidelines for clinical documentation of evaluation and management face-to-face services were developed> 20 years ago. Recently, the Centers for Medicare & Medicaid Services (CMS) have addressed office and other outpatient services and the corresponding reimbursement, intending to reduce the amount of required documentation and to alleviate clerical burden. A CMS final rule for 2021 will eliminate the history and physical examination as criteria for level of service, allow time or medical decision-making to be used as coding criteria, and will recognize a code for prolonged service.

  • Senotherapy
    • Authors: Jonathan R. Baker; Louise E. Donnelly, Peter J. Barnes
      Abstract: There is increasing evidence that COPD is a disease of accelerated lung aging, with the accumulation of senescent cells that lose their ability to repair and secrete multiple inflammatory proteins known as the senescence-associated secretory phenotype (SASP), which mimic the profile of inflammatory mediators secreted in COPD. This review discusses novel drugs (senotherapies) that target cellular senescence and which may be a promising therapeutic approach to prevent currently unaddressed disease progression and mortality in COPD.

      Abstract: Lung cancer screening, despite its proven mortality benefit, remains vastly underutilized. Previous studies examined knowledge, attitudes, and beliefs to better understand the reasons underlying the low screening rates. These investigations may have limited generalizability because of traditional participant recruitment strategies and examining only subpopulations eligible for screening. The current study used crowdsourcing to recruit a broader population to assess these factors in a potentially more general population.

      Abstract: Pulmonary arterial hypertension (PAH) is a rare disease with high mortality despite therapeutic advances. Clinical management of children with PAH is particularly challenging because of increased complexity of disease etiology and clinical presentation, and the lack of data from pediatric-specific clinical trials. In children, PAH often develops in association with congenital heart disease and other developmental disorders. Emerging data from genetic studies of pediatric-onset PAH indicate that the genetic basis is different than that of adults.

      Abstract: We recently showed that administration of the combination of the noradrenergic drug atomoxetine plus the antimuscarinic oxybutynin (ato-oxy) prior to sleep greatly reduced OSA severity, likely by increasing upper airway dilator muscle activity during sleep. In patients with OSA who performed the ato-oxy trial with an esophageal pressure catheter to estimate ventilatory drive, the effect of the drug combination (n = 17) and of the single drugs (n = 6) was measured on the endotypic traits over a 1-night administration and compared vs placebo.

      Abstract: Smoking continues to be a burden to economies and health-care systems across the world. One proposed solution to the problem has been e-cigarettes; however, because they are a relatively new product in the market, little is known about their potential health impacts. Furthermore, e-cigarettes continue to evolve at a rapid rate, making it necessary to regularly review and synthesize available studies. Although e-cigarettes are marketed as a smoking cessation tool by some manufacturers, the reality is that many nonsmokers, including youth, are using them.

      Abstract: COPD is a common respiratory disorder that poses a major health-care burden with societal and financial ramifications. Although effective inhaled therapies are available, nonadherence is common among patients with COPD and potentially contributes to the burden of this disease. Electronic inhaler monitoring (EIM) is a novel modality that enables real-time assessment of adherence to inhaled therapy and informs the assessment of treatment effectiveness. EIM can be combined with physician feedback, automated audiovisual reminders, and text messaging to bolster adherence.

      Abstract: Parasitoses are infectious diseases of global distribution, with predominance in areas of poor sanitation. Parasites cause damage through direct tissue injury and the inflammatory response generated by their migration and establishment in various organs. Thoracic involvement by parasitic disease can generate both specific and nonspecific clinical, laboratorial, and radiologic manifestations, which often makes their diagnosis challenging. The correct diagnosis is crucial for definition of treatment, which sometimes requires rapid intervention.

      Abstract: Central sleep apnea/Hunter-Cheyne-Stokes breathing (CSA/HCSB) is prevalent in patients with heart failure with reduced ejection fraction (HFrEF). The acute pathobiologic consequences of CSA/HSCB eventually lead to sustained sympathetic overactivity, repeated hospitalization, and premature mortality. A few small randomized controlled trials (RCTs) have shown statistically significant and clinically important reduction in sympathetic activity when CSA/HCSB is attenuated by oxygen or PAP therapy, using both CPAP and adaptive servoventilation (ASV) devices.

    • Authors: Fadi Aldaghlawi; Jonathan S. Kurman, Jason A. Lilly, D. Kyle Hogarth, Jessica Donington, Mark K. Ferguson, Septimiu D. Murgu
      Abstract: The concerns regarding air leak after lung surgery or spontaneous pneumothorax include detection and duration. Prior studies have suggested that digital drainage systems permit shorter chest tube duration and hospital length of stay (LOS) by earlier detection of air leak cessation. We conducted a systematic review to assess the impact of digital drainage on chest tube duration and hospital LOS after pulmonary surgery and spontaneous pneumothorax.

      Abstract: Chronic hypersensitivity pneumonitis (CHP) is an immune-mediated interstitial lung disease (ILD) caused by inhalational exposure to environmental antigens, resulting in parenchymal fibrosis. By definition, a diagnosis of CHP assumes a history of antigen exposure, but only half of all patients eventually diagnosed with CHP will have a causative antigen identified. Individual clinician variation in eliciting a history of antigen exposure may affect the frequency and confidence of CHP diagnosis.

    • Authors: Mercè Cladellas; Cora Garcia-Ribas, Mirea Ble, Miquel Gómez, Núria Farré, Aleksandra Mas-Stachurska, Consol Ivern, Joan Vila, Julio Martí-Almor
      Abstract: Severe pulmonary hypertension (PH) in patients with aortic stenosis is related to poor prognosis following aortic valve replacement (AVR). Current European PH guidelines recommend adding two different echocardiographic signs to tricuspid regurgitation velocity (TRV) in PH estimation, classifying its probability as low (TRV ≤ 2.8 m/s), intermediate (TRV 2.9-3.4 m/s), and high (TRV> 3.4 m/s). The right ventricle is an important determinant of prognosis in PH. The goal of this study was to analyze the value of right atrial area> 18 cm2 and right ventricular/left ventricular ratio> 1 in the long-term prognosis following AVR, mainly in the intermediate probability group.

      Abstract: Treatment of Mycobacterium avium complex lung disease (MAC-LD) is challenging because it requires long-term therapy with multiple antibiotics, and the treatment outcomes are relatively poor.1,2 Moreover, there is a high rate of recurrence, either by relapse or reinfection.3 Although MAC-LD treatment guidelines in the United States recommended 12 months of treatment following culture conversion,4 there is limited evidence for this approach. In addition, although reinfection is common, several studies showed that 25% to 50% of the recurrence was due to true relapse.

      Abstract: COPD is a heterogeneous syndrome. Many COPD subtypes have been proposed, but there is not yet consensus on how many COPD subtypes there are and how they should be defined. The COPD Genetic Epidemiology Study (COPDGene), which has generated 10-year longitudinal chest imaging, spirometry, and molecular data, is a rich resource for relating COPD phenotypes to underlying genetic and molecular mechanisms. In this article, we place COPDGene clustering studies in context with other highly cited COPD clustering studies, and summarize the main COPD subtype findings from COPDGene.

      Abstract: The development of a high-quality lung cancer screening (LCS) program poses many operational challenges. Compared with criteria for other cancer screening target populations, the criteria for LCS eligibility are more complex, including age, smoking history, and general health status. Furthermore, among Medicare-eligible adults who qualify for LCS, which is a substantial proportion of the target population, the Centers for Medicare & Medicaid Services (CMS) has regulatory mandates that apply to the screening process and must be met for reimbursement.

    • Authors: Margaret A. Pisani; Carolyn D’Ambrosio
      Abstract: Sleep is important to health and well-being, and studies in healthy adults have demonstrated that sleep deprivation impacts respiratory, immune, and cognitive function. Historically, because of the nature of critical illness, sleep has not been considered a priority for patient care in the ICU. More recently, research has demonstrated that sleep is markedly abnormal in patients who are critically ill. In addition, there is often disruption of circadian rhythms. Delirium is a syndrome of acute alteration in mental status that occurs in the setting of contributing factors such as serious illness, medication, and drug or alcohol intoxication or withdrawal.

      Abstract: Sleep health is a multidimensional construct that includes adequate duration, quality, and appropriately timed sleep that may be influenced by environmental factors. In this review, we focus on how an individual’s living and sleeping environment, both the surrounding neighborhood physical and social features and the atmosphere around them, may impact their sleep health. We explore the associations of the physical environment (urban density, recreational facilities, green space, mixed land use, and healthy food stores), neighborhood deprivation (disadvantage and disorder), and the social environment (social cohesion, safety, and stigma) with sleep in both adult and pediatric populations.

      Abstract: Accurate diagnosis is crucial to improve the treatment and prognosis of respiratory disease, especially lung cancer. Tumors and lesions located deep in the lung are directly accessible via dendritic tracheal bronchus, thereby opening a new way to tackle respiratory disease. Intratracheal delivery is an innovative, noninvasive approach for imaging and treating respiratory disease efficiently, when compared with other delivery methods. Intratracheal delivery of nano- and microparticles and hyperpolarized gases offers valuable clinical advantages, such as assessing lung function, monitoring ventilation and perfusion, controlling disease progression, and inhibiting tumor growth.

However, they are often limited in scope within the broader definitions of severe asthma, have insufficient statistical power to answer many research questions, lack intraoperability to share lessons learned, and have fundamental differences in data collected, making cross comparisons difficult. What is missing is a worldwide registry which brings all severe asthma data together in a cohesive way, under a single umbrella, based on standardized data collection protocols, permitting data to be shared seamlessly.

      Abstract: Mortality has long been used as a primary end point for randomized controlled trials in critical care. Recently, a plurality of trials targeting mortality end points as their primary outcome has failed to detect a difference between study arms. While there are a number of reasons for the preponderance of such neutral trials, the use of mortality as an outcome is one important consideration. We explore some of the reasons why such trials may be biased toward a neutral result, as well as reasons to consider alternative end points that are better coupled to the expected therapeutic effect.

      Abstract: Chronic lung disease accounts for a significant global burden with respect to death, disability, and health-care costs. Due to the heterogeneous nature and limited treatment options for these diseases, it is imperative that the cellular and molecular mechanisms underlying the disease pathophysiology are further understood. The lung is a complex organ with a diverse cell population, and each cell type will likely have different roles in disease initiation, progression, and resolution. The effectiveness of a given therapeutic agent may depend on the net effect on each of these cell types.

      Abstract: Treatment of pulmonary arterial hypertension (PAH) has evolved substantially over the past two decades and varies according to etiology, functional class (FC), hemodynamic parameters, and other clinical factors. Current guidelines do not provide definitive recommendations regarding the use of oral prostacyclin pathway agents (PPAs) in PAH. To provide guidance on the use of these agents, an expert panel was convened to develop consensus statements for the initiation of oral PPAs in adults with PAH.

      Abstract: Objective assessment of symptoms in bronchiectasis is important for research and in clinical practice. The COPD Assessment Test (CAT) is a short, simple assessment tool widely used in COPD. The items included in the CAT are not specific to COPD and also reflect the dominant symptoms of bronchiectasis. We therefore performed a study to validate the CAT as an outcome measure in bronchiectasis.

      Abstract: One of the best experiences of subspecialty fellowship training is the development of an original research project. Although the time, scope, and opportunities of research training and clinical training programs differ, each program has some exposure to research. For fellows interested in a career in academic medicine, this research training period is essential to developing the academic skill set necessary to establish an academic niche as junior faculty. Surprisingly, research training can be equally important for fellows geared toward careers in clinical medicine, as this experience can positively influence one’s professional skill set in multiple dimensions.

    • Authors: J. Aaron Scott; Stephen O. Heard, Maksim Zayaruzny, J. Matthias Walz
      Abstract: Expertise in airway management is a vital skill for any provider caring for critically ill patients. A growing body of literature has identified the stark difference in periprocedural outcomes of elective intubation in the operating room when compared with emergency intubation in the ICU. A number of strategies to reduce the morbidity and mortality associated with airway management in the critically ill have been described. In this review, we provide an updated framework for airway assessment before direct laryngoscopy and video laryngoscopy, and use of newer pharmacologic agents; comment on current concepts in tracheal intubation in the ICU; and address human factors around critical decision-making during ICU airway management.

      Abstract: Constrained by a limited supply of specialized personnel, health systems face a challenge in caring for the large number of patients with OSA. The complexity of this challenge is heightened by the varied clinical presentations of OSA and the diversity of treatment approaches. Innovations such as simplified home-based care models and the incorporation of nonspecialist providers have shown promise in the management of uncomplicated patients, producing comparable outcomes to the resource-intensive traditional approach.

      Abstract: Thoracic injury is common on the battlefield and in terrorist attacks, occurring in 10% to 70% of patients depending on the type of weapons used. Typical injuries seen include bullet, blast, and fragment injuries to the thorax, which are often associated with injuries to other parts of the body. Initial treatment prehospital and in the ED is carried out according to the principles of Tactical Combat Casualty Care or other standard trauma management systems. Immediately life-threatening problems including catastrophic hemorrhage are dealt with rapidly, and early consideration is given to CT scanning or rapid surgical intervention where appropriate.

      Abstract: The randomized clinical trials of bronchial thermoplasty (BT) were conducted in patients with a baseline FEV1 greater than 50%. There is a paucity of data regarding BT in patients with more severe obstruction, and consequently these patients are often excluded from receiving BT. The purpose of this study was to compare safety and efficacy outcomes in a large cohort of patients with an FEV1 less than 50% with a cohort of less obstructed patients.

      Abstract: This review focuses on recent clinical and translational discoveries in severe and uncontrolled asthma that now enable phenotyping and personalized therapies in these patients. While asthma is common in both children and adults and typically responds to standard therapies, a subset of individuals with asthma experience severe and/or persistent symptoms despite appropriate therapies. Airflow obstruction leading to frequent symptoms requiring higher levels of controller therapy is the cardinal feature of severe asthma, but the underlying molecular mechanisms, or endotypes, are diverse and variable between individuals.

      Abstract: Pulmonary infections are important causes of global morbidity and mortality, but diagnostics are often limited by the ability to collect specimens easily, safely and in a cost-effective manner. We review recent advances in the collection of infectious aerosols from patients with tuberculosis and with influenza. Although this research has been focused on assessing the infectious potential of such patients, we propose that these methods have the potential to lead to the use of patient-generated microbial aerosols as non-invasive diagnostic tests of disease as well as tests of infectiousness.

      First page: 574
      Abstract: Arterial catheterization is frequently performed in intensive care units to facilitate hemodynamic monitoring and frequent blood sampling. Overall, arterial catheterization has high success and low complication rates, but in critically ill patients the incidence of failure is higher due to hypotension, peripheral edema, and obesity. Ultrasound guidance significantly increases the likelihood of successful cannulation and decreases complications compared to traditional landmark-based techniques. Multiple ultrasound techniques for radial and femoral arterial catheter insertion have been described; this article presents an approach for incorporating these tools into bedside practice, including illustrative figures and narrated video presentations to demonstrate the techniques described.

      First page: 673
      Abstract: Patients with chronic kidney disease have increased morbidity and mortality, mainly due to cardiovascular disease. Compared to the general population, patients with chronic kidney disease have an increased prevalence of both obstructive and central sleep apnea, and the presence of sleep apnea in this population has been associated with an increased risk of cardiovascular events and mortality. While obstructive sleep apnea can lead to an increase in the rate of kidney function decline, there is also evidence that the presence of end stage renal disease can lead to worsening of sleep apnea, indicating a bidirectional relationship between sleep apnea and chronic kidney disease.

      Abstract: There remains debate over the best invasive diagnostic modality for mediastinal nodal evaluation. Prior studies have limited generalizability and insufficient power to detect differences in rare adverse events. We compared the risks and costs of endobronchial ultrasound-guided nodal aspiration (EBUS) and mediastinoscopy performed for any indication in a large national cohort.

      First page: 702
      Abstract: Thoracentesis can be accomplished by active aspiration or drainage with gravity. We investigated whether gravity drainage could protect against negative-pressure related complications, such as chest discomfort, re-expansion pulmonary edema or pneumothorax, compared to active aspiration.

  • State of the Art: Interventional Pulmonology
    • Authors: Momen M. Wahidi; Felix JF. Herth, Alexander Chen, George Cheng, Lonny Yarmus
      First page: 724
      Abstract: Interventional Pulmonology (IP) has evolved over the last decade from an obscure subspecialty in pulmonary medicine to a recognized discipline offering advanced consultative and procedural services to patients with thoracic malignancy, anatomical airway diseases and pleural pathology. Innovative Interventions are now also available for diseases not traditionally treated procedurally such as asthma and emphysema. The IP field has established certification examinations and training standards for IP training programs in an effort to enhance training quality and ensure competency.
