    • Authors: Tiana R. Endicott-Yazdani; Robert W. Baird, Meghan S. Koch, Alastair J. Moore, Ariel M. Modrykamien
      Abstract: A 55-year-old woman with COPD, heart failure with preserved ejection fraction (congestive heart failure), diabetes mellitus, and hypertension presented with baseline dyspnea at rest that had worsened over the last week. She reported associated runny nose, congestion, and cough productive of green sputum. She smoked six cigarettes per day and denied alcohol, drugs, or occupational exposure. She was admitted and initiated on treatment for acute exacerbation of COPD; however, her condition did not improve with steroid, ceftriaxone, and nebulized albuterol and budesonide treatments.

      Abstract: A 2-year-old boy was referred to the Ankara University School of Medicine Children’s Hospital with a history of recurrent respiratory distress and cyanosis since birth. His medical history was significant for premature birth at 31 weeks via cesarean section, as an infant of a diabetic mother. There was no parental consanguinity. He was hospitalized in the neonatal ICU after birth because of respiratory distress. After receiving invasive mechanical ventilation for 4 days, noninvasive mechanical ventilation and oxygen therapy were given gradually.

      Abstract: A 33-year-old white man presented to the ED with 1-month history of worsening dyspnea. He experienced gradual onset of right-sided scapular pain and shortness of breath on exertion that progressively worsened over the course of 1 month. He had a mild nonproductive cough and intermittent subjective fevers and reported weight loss of approximately 2 kg over 1 month. He had a history of two episodes of acute pancreatitis that was thought to be autoimmune in origin. He was a never smoker; he denied illicit drug use or recent alcohol consumption.

    • Authors: John Odackal; Tijana Milinic, Tim Amass, Edward D. Chan, Jeremy Hua, Silpa Krefft
      Abstract: A 28-year-old man presented with shortness of breath, chest pain, and scant hemoptysis. Three weeks previously, he was admitted for coronavirus disease 2019 pneumonia that had been diagnosed by nasal swab polymerase chain reaction. Chest CT imaging demonstrated bilateral ground-glass opacities without evidence of VTE. He was treated with hydroxychloroquine, up to 7 L/min oxygen, and self-proning. After 8 days of hospitalization, he was discharged on 4 L/min oxygen. After discharge, his symptoms and hypoxia resolved.

    • Authors: Fahad Gul; Daniel Casey, Sumeet Mainigi, Glenn Eiger, Abesh Niroula
      Abstract: A 65-year-old woman with a history of chronic persistent atrial fibrillation, tobacco use, and COPD was admitted to the hospital 2 months after catheter ablation for persistent atrial fibrillation and dyspnea. Her dyspnea was present at rest and worsened by exertion with limitation to ambulating less than two blocks. She also endorsed a 1-month history of cough with minimally productive whitish sputum with frequent nocturnal exacerbations and orthopnea. She denied any fevers, chest pain, or hemoptysis.

  • A 49-Year-Old Man Presents With Fever of Unknown Origin and Cough
    • Authors: Yongjin Ji; Peixia Yu, Changqing Zhao
      Abstract: A 49-year-old man presented with 3 months of persistent fever, cough, shortness of breath, and chest tightness. He had no response to treatment with antibiotics. He had been treated with an empiric 2-week course of steroids approximately 2 months before presentation, with mild and transient improvement. He did not use tobacco and had not experienced any weight loss, hemoptysis, arthralgia, or myalgia, and was otherwise in good health. He denied contact with anyone with pulmonary TB or other respiratory illnesses.

  • A 56-Year-Old Man With Chronic Cough, Hemoptysis, and a Left Lower Lobe
           Infiltrate
    • Authors: Alexandra Miller; Janelle Wenstrup, Sanja Antic, Chirayu Shah, Robert J. Lentz, Parker Panovec, Pierre P. Massion
      Abstract: A 56-year-old man presented to the lung nodule clinic with abnormal chest imaging prompted by a chronic cough and hemoptysis. Approximately 2.5 years earlier, while kneeling beside his car fixing a flat tire, he fell backwards while holding the tire cap in his mouth, causing him to inhale sharply and aspirate the cap. He immediately developed an intractable cough productive of flecks of blood. He presented to an emergency room but left before being seen because of a long wait time and his lack of health-care insurance.

  • Case of a 21-Year-Old Man With Hemoptysis, Recurrent Pneumothorax, and

    • Authors: Sang Yong Park; Ho Cheol Kim, Seongbong Wee, Yeon Joo Kim, Chae-Man Lim, Yong-Gil Kim, Geun Dong Lee, Seungjoo Lee, Hee Sang Hwang, Se Jin Jang, Beom Hee Lee, Won-Kyung Cho
      Abstract: A 21-year-old man was admitted to our hospital with recurrent bilateral pneumothorax and hemoptysis. Three years earlier, he underwent coil embolization due to a subarachnoid hemorrhage caused by an intracerebral aneurysm rupture. Two months after the coil embolization, he underwent an emergent total colectomy due to a massive infarction of the colon. One year after the colectomy, he started to have recurrent hemoptysis, and a few months later, multiple episodes of bilateral pneumothorax that required a chest tube placement began to occur.

  • Reversal of Acute Right Ventricular Failure Early Post Left Ventricular
           Assist Device Placement by Intratracheal Milrinone Administration
    • Authors: Ying Tung Sia; Caroline E. Gebhard, André Y. Denault
      Abstract: A 58-year-old man with medical history of hypertension and pulmonary sarcoidosis presented with palpitation and syncope. At arrival in the ED, multiple episodes of nonsustained ventricular tachycardia have been recorded. Transthoracic echocardiography (TTE) showed severe left ventricular dysfunction with suspected cardiac sarcoidosis. Shortly after admission, the patient went into cardiac arrest due to refractory ventricular tachycardia. CPR was performed, and venous-arterial extracorporeal membrane oxygenation was inserted through a femoral approach without complication.

  • A 58-Year-Old Man With Abdominal Ascites
    • Authors: Zeina Almajthoub; Majdi AlNabulsi, Vibhu Sharma
      Abstract: A 58-year-old man with a history of active alcohol use presented to the ED with a 3-week history of nausea and abdominal discomfort. A CT scan of the abdomen with oral contrast showed mild distention of the stomach and first and second portions of the duodenum without definite obstructing mass. Bowel wall thickening “consistent with enteritis” was noted, as was ascites and a cirrhotic liver. He was discharged with advice to abstain from alcohol and advised to follow up with his primary care physician.

  • A 17-Year-Old With Becker Muscular Dystrophy and Unusual Polysomnography
           Findings
    • Authors: Grace R. Paul; Rami N. Khayat, Kavitha Kotha, Deipanjan Nandi, Linda Cripe, Richard Shell
      Abstract: A 17-year-old male patient who was diagnosed with Becker muscular dystrophy (nonsense mutation [c.3822C>A] within exon 28 of the DMD gene) at 6 years of age was evaluated in the multidisciplinary neuromuscular clinic for loss of ambulation for 1 year. From a pulmonary perspective, there were no acute or chronic respiratory symptoms, and no history of pneumonia or aspiration. Clinical examination revealed a nonambulant teenager, with normal oxygen saturation and end-tidal CO2 when awake, no respiratory distress, and symmetrically diminished aeration due to obesity (BMI 40 kg/m2).

  • Sclerosing Pneumocytoma
    • Authors: Nora Mayer; Giovanni Luca Carboni, Andrea Thielken, Dirk Wagnetz
      Abstract: Sclerosing pneumocytoma (SP) is a rare primary lung tumor. Typical carcinoids (TCs) count for 2% of lung malignancies. A description of a combined neoplasm of SP with a nodal and pleural metastasized TC has, to our knowledge, never been published. A 57-year-old actively smoking woman received a diagnosis of a lesion in the left lower lobe via a screening CT scan for rheumatoid arthritis. A fluorodeoxyglucose-PET scan confirmed a 21 × 26 × 16 mm (standardized uptake maximum value, 3.0), well-circumscribed round lesion with calcification, which was thought to be most probably benign.

  • More Movement for Better Control
    • Authors: Anne E. Holland; Arwel W. Jones
      Pages: 1 - 2
      Abstract: The Global Initiative for Asthma recommends that adults with asthma should engage in regular physical activity for its general health benefits.1 The majority of trials to date have involved structured physical activity interventions in the form of exercise training. A recent systematic review indicated that aerobic exercise training improves asthma control and lung function in adults with asthma.2 Despite the clear potential of formal supervised exercise interventions in improving asthma outcomes,2 personal preferences and barriers to physical activity mean it is unlikely that a one-size-fits-all approach is suitable.

  • Introducing the Adult Cystic Fibrosis Series
    • Authors: Nicholas J. Simmonds
      Pages: 3 - 4
      Abstract: Cystic fibrosis (CF) has come a long way since its first description in 1938 by the pathologist Dorothy Andersen.1 What was then a fatal condition in childhood with a>90% mortality rate in the first year of life has now been transformed into a disease across the age spectrum for which survival well into adulthood is expected in most countries. Treatments have progressed dramatically from basic, but important, supportive and symptomatic interventions to state-of-the-art highly effective targeted therapies.

  • Interstitial Lung Abnormality Incidentally Detected on CT
    • Authors: David A. Lynch
      Pages: 5 - 6
      Abstract: With increasing use of chest CT scans for diagnosis and for lung cancer screening, the high prevalence of incidentally detected interstitial lung abnormality (ILA) in the lung parenchyma in older individuals has become apparent. In nine studies of CT scans that were performed for lung cancer screening or for epidemiologic purposes, including a total of 28,580 subjects, the prevalence of ILA ranged from 3% to 17%, with a mean of 8%. ILAs are present primarily in older subjects; the mean age of subjects with ILA in these studies ranged from 60 to 78 years old.

      Abstract: In this issue of CHEST, Janz et al1 share the results of their study about integrating a clinical protocol when caring for critically ill patients with coronavirus disease 2019 (COVID-19). This particular retrospective, observational cohort study took place in four hospitals in New Orleans from early March to mid-April 2020. The authors focused their efforts in two major areas: (1) they wished to see if utilizing an evidence-based protocol would be associated with improved outcomes, and (2) they analyzed outcomes in their critically ill patients with COVID-19 who were admitted to so-called “safety-net” hospitals (SNH).

  • The Pursuit of Risk Assessment and Stratification Tools in Pulmonary
           Arterial Hypertension
    • Authors: H. James Ford; Barbara LeVarge
      Pages: 14 - 16
      Abstract: Initial and ongoing risk assessment in pulmonary arterial hypertension (PAH) is key in determining class and intensity of PAH-specific therapy, discussing prognosis, and optimizing timing for lung transplant referral. Treatment guidelines advocate for achievement and maintenance of low-risk status. In the last decade, tools to assess risk systematically have emerged, with the use of objective metrics beyond clinician gestalt. These instruments are derived from large clinical registries. Registry to Evaluate Early and Long-Term PAH Disease Management (REVEAL), a prospective study of>3,500 patients in the United States, led to the development of the first REVEAL Registry risk calculator (REVEAL 1.0).

      Abstract: Sleep-disordered breathing (SDB) is common during pregnancy, it is associated with maternal obesity, and its incidence is likely to increase given the global rise in obesity among women. Objectively determined SDB occurs in 15% to 70% of metabolically complicated pregnancies, with multiple studies showing an association between SDB and gestational diabetes mellitus (GDM).1 GDM, defined as glucose intolerance diagnosed in pregnancy, is one of the most common obstetric complications, affecting 7% to 18% of pregnancies and is an important risk factor for maternal and neonatal morbidities.

      Abstract: Few things remain as elusive in medicine as understanding how to protect the human brain. Whereas there has been substantial clinical and scientific progress in other domains such as cardiovascular and cancer care, ways to concretely and systematically prevent cognitive decline remain undefined. Accordingly, as the medical care for critical illness becomes more advanced and more lives are saved, the short- and long-term neurocognitive consequences of an ICU stay are becoming increasingly apparent and important to address.

      Abstract: Since the first lung resection for a tumor in 1861 by Pean,1 thoracic surgery has evolved considerably and now offers patients widely available, minimally invasive surgical options aimed at maintaining excellent oncologic outcomes. The pursuit of further improvement in disease-free survival with an ever-increasing multimorbidity population has led to the emergence of segmentectomy as the natural progression of parenchymal sparing operative techniques.2

      Pages: 23 - 24
      Abstract: The important article by Tabriz et al1 in this issue of CHEST points out that Centers for Medicare and Medicaid Services requires shared decision-making (SDM) (ie, patient screening eligibility assessment, education about lung cancer screening [LCS], use of a decision support intervention to clarify patient screening preference, and counseling about annual screening, follow up, and smoking cessation) for reimbursement of initial screening. In the United States, however, SDM occurs infrequently, and LCS rates are low.

  • POINT: Should Corticosteroids Be Routine Treatment in Early ARDS' Yes
    • Authors: Gianfranco Umberto Meduri; Bram Rochwerg
      Pages: 25 - 29
      Abstract: ARDS is a catastrophic illness of multifactorial etiology characterized by a stereotypical severe and diffuse inflammatory exudate of the pulmonary lobules that lead to acute hypoxemic respiratory failure that requires mechanical ventilation (MV) for life support. Clinically, ARDS progresses trough three temporal phases: acute (respiratory failure), subacute (postextubation), and chronic (after hospital discharge). ARDS is associated with a substantial public health impact. It is a relatively common disease (10% of all patients who are admitted to ICUs; 200,000 cases in United States each year), is associated with 35% to 45% hospital deaths,1 leads to significant long-term disability in survivors (correlating with the duration of MV),2 and portends a huge health care cost.

  • COUNTERPOINT: Should Corticosteroids Be Routine Treatment in Early
           ARDS' No
    • Authors: Matthew K. Hensley; Michael W. Sjoding, Hallie C. Prescott
      Pages: 29 - 33
      Abstract: To answer the question of whether to use steroid therapy routinely in early ARDS, we must first acknowledge that ARDS is a heterogeneous clinical syndrome that may result from a variety of underling diseases, which include pneumonia, aspiration, pancreatitis, shock, trauma, drugs, drowning, fat emboli, and blood transfusion. Despite its seemingly straightforward definition, there is poor agreement on ARDS diagnosis across clinicians.1 And, although the pathologic correlate of ARDS is diffuse alveolar damage, only 45% of patients whose condition meets the clinical criteria for ARDS have diffuse alveolar damage on autopsy.

      Abstract: Drs Meduri and Rochwerg1 highlight important points regarding steroids use in early ARDS. We agree that ARDS is a severe, debilitating, and costly disease with a large public health impact. Similarly, we agree that a recent meta-analysis2 and randomized trial3 have found benefit with steroid use. However, we differ on how to apply this information to bedside clinical practice.

      Abstract: The points raised by Hensley et al1 regarding the heterogeneity of ARDS trigger, presentation, pathologic condition, and clinical course are well taken. Yet, despite different causes, the biologic and histologic characteristics of ARDS are quite similar and consistent with a corticosteroid-responsive disease. Across clinical phenotypes of ARDS, degree of severity in systemic and pulmonary inflammation (hypo- vs hyperinflammatory subphenotypes) is the primary determinant of outcome.2,3 And irrespective of cause, progression to fibroproliferation, with persistent elevation in markers of inflammation and coagulation, is shared by all clinical phenotypes and is corticosteroid-responsive.

      Abstract: Unlike other pandemics, coronavirus disease 2019 (COVID-19) has required hospitals to increase their ICU capacity, specifically in their ability to provide mechanical ventilation (MV) for a great number of patients. Nearly 115,000 ventilators were projected to be needed at the peak of the US COVID-19 outbreak.1 Many centers have been able to increase not only their surge capacity but also fulfill the staffing deficit required for such growth. However, a previously documented underlying necessity2 has now resurfaced: personnel trained in MV are desperately needed.

      Abstract: The American College of Chest Physicians recommends that low-dose chest CT be offered to patients ages 55 to 77 years who have smoked 30 pack-years or more and either continue to smoke or have quit within the past 15 years.1 However, the bulk of medical literature leaves air pollution unaddressed, despite its rapid rise affecting nearly the entire global population. Pollution in many locations equals the carcinogenic risk of cigarettes. The scope of this exposure cannot be understated, with at least 95% of the world’s population breathing unhealthy air (Fig 1).

  • An Evaluation of Bronchoscopy Diagnostic Yield
    • Authors: Matthew Aboudara; Otis B. Rickman, Fabien Maldonado
      Pages: 437 - 438
      Abstract: In a previous issue of CHEST (June 2020), Silvestri and colleagues1 published a study that underscores key components in preparation for diagnostic bronchoscopy. Using a dataset from a genomic classifier validation study, the investigators incorporated clinician pretest probability into a multivariate logistic regression model and, not surprisingly, found a higher diagnostic yield with a higher pretest probability of cancer and a lower diagnostic yield with a lower pretest probability. In addition, the authors conclude that more careful patient selection for bronchoscopy needs to be considered, and perhaps bronchoscopy should not be the initial diagnostic test of choice for peripheral pulmonary nodules (PPN) unless there is lymphadenopathy or central tumors in which a needle can be visualized in the lesion under real-time ultrasound guidance.

There exists a scientific graveyard strewn with quotes such as “not surprisingly” until one is surprised, and “it has been known for years” when “it” has only recently been proven in a randomized setting, or “we feel the findings are overly simplistic,” despite the fact that science has little to do with feelings and everything to do with proof.

      Pages: 442 - 443
      Abstract: We read with great interest the article by Shah et al1 in CHEST (June 2020). They report a significant association between use of inhaled corticosteroids (ICS) in higher doses for a longer duration of time with tracheobronchomalacia in patients with COPD and asthma. The authors postulate that ICS could cause tracheobronchomalacia and be a risk for tracheobronchomalacia. That is an important and eye-opening message for clinicians because we occasionally overlook tracheobronchomalacia. Another interpretation for their findings is that they may incorrectly use ICS for tracheobronchomalacia as severe asthma or COPD.

They have also indicated that a causal relationship cannot be inferred because pretreatment inhaled corticosteroids (ICS) data are not available. Although these observations are valid, we would like to bring to light the intent of our study and would want the readership to acknowledge the retrospective nature of our study.

      Abstract: Comparing a new diagnostic with available methods to gain some idea about its performance at the early stage of usage is necessary. When the new diagnostic has evidently better sensitivity than the reference, poor specificity will surely be incurred. A latent class analysis has been introduced to overcome this disadvantage1; however, it had seldom been used for TB diagnostic evaluation. Complexity and the need for knowledge of mathematics or statistics might be the main reasons impeding its application.

  • Zinc and Coronavirus Disease 2019

      Abstract: We read with interest the article by Yao et al1 this issue of CHEST whereby they have studied the effect of zinc supplementation in hospitalized patients of coronavirus disease 2019 (COVID-19) infection.1 In reference to the patient assessment parameters and results, one very important aspect needs attention. Although the authors have evaluated in detail the baseline clinical and treatment characteristics, they have no data pertaining to serum zinc levels before or after zinc supplementation. We do understand because this was a retrospective analysis with waiver of consent, but one should be cautious about the interpretation of results in this scenario.

      Abstract: We thank Dr Khurana et al for their thoughtful response to our letter1 and for pointing out the value of serum zinc levels. Our study assessed the association between zinc supplementation and survival among hospitalized patients with coronavirus disease 2019 (COVID-19), using a causal inference approach to retrospective data. Our institutions do not routinely measure serum zinc levels. Although our study population consisted of patients admitted to a single hospital, our study assessed the effect of zinc in the contexts in which it was routinely used in the inpatient setting at the peak of the COVID-19 pandemic in the United States.

  • Personalized Medicine for OSA Syndrome in a Nutshell
    • Authors: Christophe Gauld; Marie Darrason, Guillaume Dumas, Jean-Arthur Micoulaud-Franchi
      Pages: 451 - 452
      Abstract: In 2011, personalized medicine was defined as “the tailoring of medical treatment to the individual characteristics of each patient.”1 Since then, the term has been used widely in the field of Sleep Medicine, especially in the context of OSAS syndrome in CHEST.2,3 However, the term personalized medicine is related to a wider range of concepts that can overlap1 (Fig 1) for OSA syndrome. Despite a growing interest in this field, clarification is needed, especially concerning the conceptual structure of personalized medicine for OSA syndrome and how it may help in unifying the field.

      Pages: 452 - 453
      Abstract: We read with great interest the editorial by Fujii and Udy1 in CHEST (July 2020) and appreciate their comments. In their editorial, Fujii and Udy1 fail to mention the issue of timing, however. Sepsis is a time-sensitive disease, and time to intervention is critical. Indeed, in our study, all patients were enrolled within 12 h of presenting to the ED.2 Although our study was underpowered for a mortality benefit, the early treatment may explain the reduction in vasopressor requirement. In the accompanying Combined Treatment With Hydrocortisone, Vitamin C and Thiamine for Sepsis and Septic Shock (HYVCTTSSS) study, Chang et al3 report a mortality reduction in those patients with a sepsis duration < 48 h.

  • Variability and Misclassification of Sleep Apnea Severity Based on
           Multi-Night Testing
    • Authors: Mahadevappa Hunasikatti
      Pages: 453 - 454
      Abstract: I read with interest the article by Punjabi et al1 in CHEST (July 2020). The authors state that “the reference AHI was obtained as the posterior mean.” However, this may not be the ideal AHI (apnea hypopnea index) value that should be compared. Despite limitations, polysomnogram is still the gold standard diagnostic test of choice, until we have a reliable alternate home sleep testing that has approximately the same sensitivity and specificity in ruling in and ruling out OSA. Their concern about polysomnogram (PSG) limitation, “It is well established that on the first night in a sleep laboratory, normal subjects and patients with sleep disorders exhibit alterations in sleep quality,” is justified.

      Abstract: We thank Brenner et al for their interest in our consensus statement1 and for highlighting specific considerations relevant to performing tracheostomy during the coronavirus disease 2019 (COVID-19) pandemic. In their letter, Brenner et al cite the need to balance risk reduction of infection transmission among health-care workers during an aerosol-generating procedure, such as tracheostomy, while optimizing patient safety and readiness for the procedure. We agree that, for specific aerosol-generating procedures, the uncertainty and lack of definitive best practices regarding risk reduction early in the pandemic may have led to a preferential focus on health-care worker safety.

      Abstract: Arguably, no scientific discovery in recent memory has been as eagerly awaited as the development of a vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). With countless lives on standby until a vaccine is available, demand will almost certainly outstrip the initial supply. Furthermore, vaccination will have unprecedented social, economic, and political implications. During this pandemic, we have seen individuals, health-care systems, and governments hoard medical resources, including medications (eg, hydroxychloroquine, remdesivir), personal protective equipment, and life-sustaining equipment (eg, ventilators).

  • “Protein biomarkers for COPD outcomes”
    • Authors: Karina A. Serban; Katherine A. Pratte, Russell P. Bowler
      Abstract: Chronic obstructive pulmonary disease (COPD) is a clinically heterogeneous syndrome characterized by injury to airways, airspaces and lung vasculature and usually caused by tobacco smoke and/or air pollution exposure. COPD is also independently associated with non-pulmonary comorbidities (e.g. cardiovascular disease) and malignancies (e.g. gastrointestinal and bladder), suggesting a role for systemic injury. Since not all those with exposure develop COPD, there has been a search for plasma and lung biomarkers that confer increased cross-sectional and longitudinal risk.

      Abstract: NLP successfully identified a large cohort with CC. Most patients were identified through NLP alone, rather than diagnoses or medications. NLP improved detection of patients nearly seven-fold, addressing the gap in ability to identify and characterize CC disease burden. Nearly all cases appeared to be managed in primary care. Identifying these patients is important for characterizing treatment and unmet needs.

      Abstract: Pulmonary arterial hypertension (PAH) is a rare disease and much of our understanding stems from single-center studies, which are limited by sample size and generalizability. Administrative data offer an appealing opportunity to inform clinical, research, and quality improvement efforts for PAH. Yet, there is currently no standardized, validated method to distinguish PAH from other subgroups of pulmonary hypertension (PH) within this data source.

      Abstract: To assess airway and lung parenchymal damage non-invasively in cystic fibrosis (CF), chest MRI has been historically out of the scope of routine clinical imaging due to technical difficulties such as the low proton density and respiratory and cardiac motion. However, technological breakthroughs have recently emerged to dramatically improve lung MRI quality (including signal-to-noise ratio, resolution, speed, contrast). At the same time, novel treatments have changed the landscape of CF clinical care.

    • Authors: Karin Klooster; Dirk-Jan Slebos
      Abstract: Bronchoscopic lung volume reduction with one-way endobronchial valves is a guideline treatment option for patients with advanced emphysema, supported by extensive scientific data. Patients limited by severe hyperinflation, with a suitable emphysema treatment target lobe and with absence of collateral ventilation are the responders to this treatment. Detailed patient selection, a professional treatment performance, and dedicated follow-up of the valve treatment, including management of complications, are key ingredients to success.

      Abstract: Chronic Obstructive Pulmonary Disease (COPD) may cause profound dyspnea, functional impairment, and reduced quality of life. Available pharmacologic therapy provides suboptimal symptom improvement in many patients. Bronchoscopic lung volume reduction (BLVR), achieved with endobronchial valve (EBV) placement, can effectively improve dyspnea and functional status in appropriately selected patients. Operationalizing a safe and effective BLVR program requires appropriate oversight which can be achieved by a BLVR Nurse Coordinator (NC).

      Abstract: Intravenous pushes of phenylephrine may be utilized for patients with septic shock with the intent of rapidly achieving mean arterial pressure (MAP) goals. However, the clinical effectiveness and safety of this approach is unclear. Therefore, we sought to answer the question, in patients with septic shock, is administration of a phenylephrine push prior to norepinephrine initiation associated with a higher incidence of hemodynamic stability'

      Abstract: The COVID-19 pandemic has presented novel challenges for the entire healthcare continuum, requiring transformative changes to hospital and post-acute care, including clinical, administrative, and physical modifications to current standards of operations. Innovative use and adaptation of long-term acute care hospitals (LTACHs) can safely and effectively care for patients during the ongoing COVID-19 pandemic. A framework for the rapid changes, including increasing collaboration with external healthcare organizations, creating new methods for enhanced communication, and modifying processes focused on patient safety and clinical outcomes, is described for a network of 94 LTACHs.

      Abstract: The primary curative treatment for thymic malignancies is surgery. For lung and esophageal cancer, there are substantive disparities in outcomes by race. Much of these disparities are attributed to the decreased utilization of surgery in African-American (AA) patients. Though thymic malignancies are treated by the same group of specialists as lung and esophageal cancer, it is not known if there are racial disparities in the treatment of thymic malignancies.

      Abstract: Organizational culture matters. Culture is a key driver of organizational performance and underpins the strategy that was discussed in a companion paper in this series. As previously discussed, if the strategy is the plants and the garden plan for a garden, the culture is the soil. Without a healthy culture, nothing will grow, irrespective of how well planned the garden or how beautiful the individual flowers.Using the case of establishing the culture in an institute at the Cleveland Clinic, the paper examines an approach to establishing and maintaining an organizational culture.

      Abstract: Multisystem inflammatory syndrome in children (MIS-C) has become a recognized syndrome, whereas a parallel syndrome in adults has not been well defined. MIS-C was first reported in April 2020 as a hyperinflammatory syndrome with variable features of Kawasaki disease.1 Most cases occur several weeks following confirmed or suspected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children or young adults (≤ 21 years of age) who develop severe illness. The syndrome is typically characterized by fever, markedly elevated inflammatory biomarkers, and multiple organ system involvement, frequently with prominent GI symptoms.

      Abstract: As tobacco use remains one of the leading causes of disease, disability, and mortality, tobacco treatment programs should be integrated into medical systems, such as hospitals and outpatient centers. Medical providers have a unique, high-impact opportunity to initiate smoking cessation treatment with patients. However, there are several barriers that may hinder the development and implementation of these programs. The purpose of this review is to address such barriers by illustrating several examples of successful tobacco treatment programs in US healthcare systems that were contributed by the authors.

      Abstract: In patients with cardiogenic shock, NSTE-MI and LBBB-MI presentations reflect higher risk profiles than STE-MI but are not independent risk factors of mortality. ECG presentations did not modify the treatment effect, supporting culprit-lesion-only PCI as the preferred strategy across the AMI spectrum.

  • Providing Outpatient Telehealth in the United States: Before and During
           COVID-19
    • Authors: Joshua J. Brotman; Robert M. Kotloff
      Abstract: Before COVID-19, telehealth evaluation and management services were not widely utilized in the United States and often restricted to rural areas or locations with poor access to care. Most Medicare beneficiaries could not receive telehealth services in their homes. In response to the COVID-19 pandemic, Medicare, Medicaid, and commercial insurers relaxed restrictions on both coverage and reimbursement of telehealth services. These changes, together with the need for social distancing, transformed the delivery of outpatient evaluation and management services through an increase in telehealth utilization.

      Abstract: Increased acinar ventilation heterogeneity may be a consequence of previous exacerbations or highlight a group of patients prone to exacerbations. Measures of SAD were strongly associated with neutrophilic inflammation in the small airways of FE supporting the hypothesis that frequent exacerbations are associated with small airway disease related to increased cellular inflammation.

      Abstract: Worldwide, healthcare professionals are experiencing unprecedented stress related to the COVID-19 pandemic. Responding to a new virus for which there is no effective treatment yet and no vaccine, is beyond challenging. Moral distress, experienced when clinicians are unable to act in the way that they believe they should, is often experience when dealing with end-of-life care issues, as well as insufficient resources. Both factors have been widespread during this pandemic, particularly when patients are dying alone, and lack of personal protection equipment plague many overburdened healthcare systems.

      Abstract: Among hospitalized patients with COVID-19, the overall estimated pooled incidence of VTE was 17.0%, with higher rates with routine screening, inclusion of distal DVT and subsegmental PE, in critically ill patients, and in prospective studies. Bleeding events were observed in 7.8% of patients and were sensitive to use of escalated doses of anticoagulants, and nature of data collection. Additional studies are required to ascertain the significance of various thrombotic events and to identify strategies to improve patient outcomes.

    • Authors: Amy L. Bellinghausen; Jess Mandel
      Abstract: Advising patients prior to air travel is a frequently overlooked, but important role of the physician, particularly primary care providers and pulmonary specialists. Although physiologic changes occur in all individuals during air travel, those with underlying pulmonary disease are at increased risk of serious complications, and require a specific approach to risk stratification. We discuss the available tools for assessing pre-flight risk, as well as strategies to minimize potential harm. We also present a case discussion to illustrate our approach to assessing patients for air travel, and discuss the specific conditions that should prompt a more thorough pre-flight workup.

      Abstract: The clinical research we do to improve our understanding of disease and development of new therapies has temporarily been paused or delayed as the global healthcare enterprise has focused its attention on those impacted by COVID-19. While rates of SARS-CoV-2 infection are decreasing in many areas, many locations continue to have a high prevalence of infection. Nonetheless, research must continue and institutions are considering approaches to re-starting non-COVID related clinical investigation. Those restarting respiratory research must navigate the added planning challenges that take into account outcome measures that require aerosol generating procedures.

    • Authors: Mario V. Fusaro; Christian Becker, Daniel Miller, Ibrahim F. Hassan, Corey Scurlock
      Abstract: We found a reduction in risk-adjusted ICU mortality with implementation of Tele-ICU driven predominantly within the PM admission group. The PM admission SMR was 1.30 which may suggest an association with pre Tele-ICU implementation SMR>1 and mortality reduction. Future studies should seek to confirm this finding and explore other important Tele-ICU outcomes in the context of observed to expected ratios.

  • Air Pollution and Asthma – Mechanisms of Harm and Considerations for
           Clinical Interventions
    • Authors: Paul E. Pfeffer; Ian S. Mudway, Jonathan Grigg
      Abstract: There is global concern regarding the harmful impact of polluted air on the respiratory health of asthmatic patients. Multiple epidemiological studies have shown ongoing associations between high levels of air pollution and poor early-life lung growth, development of allergic sensitisation, development of asthma, airway inflammation, acutely impaired lung function, respiratory tract infections and asthma exacerbations. However, studies have often yielded inconsistent findings and not all studies have found significant associations – this may relate to both variations in statistical, measurement and modelling methodologies between studies, as well as differences in the concentrations and composition of air pollution globally.

  • Race Correction and Spirometry: Why History Matters
    • Authors: Lundy Braun
      Abstract: In recent months, medical institutions across the U.S. redoubled their efforts to examine the history of race and racism in medicine, in classrooms, in research, and in clinical practice. In this essay, I explore the history of racialization of the spirometer, a widely used instrument in pulmonary medicine to diagnose respiratory diseases and to assess eligibility for compensation. Beginning with Thomas Jefferson, who first noted racial difference in what he referred to as “pulmonary dysfunction,” to the current moment in clinical medicine, I interrogate the history of the idea of “correcting” for race and how researchers explained difference.

      Abstract: Management of Mycobacterium avium complex (MAC) lung disease is complicated, frequently unsuccessful and frustrating to patients and clinicians. The initial treatment effort may not be solely directed at MAC infection, rather it is often initiating airway clearance measures for bronchiectasis. The next important steps are deciding who to treat and when to initiate therapy. Definitive or unambiguous guidance for these decisions is often elusive. The evidence supporting the current macrolide-based regimen for treating MAC lung disease is compelling.

Approximately 16% of patients with Sjögren’s demonstrate pulmonary involvement with higher mortality and lower quality of life. Clinical practice guidelines for pulmonary manifestations of Sjögren’s were developed by the Sjögren’s Foundation after identifying a critical need for early diagnosis and improved quality and consistency of care.

      Abstract: The Hospital Readmissions Reduction Program (HRRP) was developed and implemented by the Centers for Medicare and Medicaid Services to curb the rate of 30-day hospital readmissions for certain common and high impact conditions. In October 2014, chronic obstructive pulmonary disease (COPD) became a target condition for which hospitals were penalized for excess readmissions. The appropriateness, utility and potential unintended consequences of the metric have been a topic of debate since it was first enacted.

      Abstract: Drowning is “the process of experiencing respiratory impairment from submersion or immersion in liquid”. According to WHO, drowning claim the lives of more than 40 people every hour of every day. Drowning involves some physiological principles and medical interventions that are unique. It occurs in a deceptively hostile environment that involves an underestimation of the dangers or an overestimation of water competency. It has been estimated that more than 90% are preventable. When water is aspirated into the airways, coughing is the initial reflex response.

      Abstract: Early intravenous fluid administration remains one of the modern pillars of sepsis treatment, however, questions regarding amount, type, rate, mechanism of action and even the benefits of fluid remain unanswered. Administering the optimal fluid volume is important as overzealous fluid resuscitation can precipitate multiorgan failure, prolong mechanical ventilation and worsen patient outcomes. After the initial resuscitation, further fluid administration should be determined by individual patient factors and measures of fluid responsiveness.

      Abstract: Subsolid nodules are common on chest CT and may be either benign or malignant. Their varied features, and broad differential diagnoses present management challenges. While subsolid nodules often represent lung adenocarcinomas, other possibilities are common, and influence management. Practice guidelines exist for subsolid nodule management for both incidentally and screening-detected nodules, incorporating patient and nodule characteristics. This review will highlight similarities and differences amongst these algorithms, with the intent of providing a resource for comparison, and aid in choosing management options.

      Abstract: Dyspnea is an uncomfortable sensation with the potential to cause psychological trauma. Patients presenting with acute respiratory failure, particularly when tidal volume is restricted during mechanical ventilation, may experience the most distressing form of dyspnea known as air hunger. Air hunger activates brain pathways known to be involved in post-traumatic stress disorder (PTSD), anxiety, and depression. These conditions are considered part of the post-intensive care syndrome. These sequelae may be even more prevalent among patients with acute respiratory distress syndrome (ARDS).

      Abstract: Disparities in sleep health are important but under-recognized contributors to health disparities. Understanding the factors contributing to sleep heath disparities and developing effective interventions are critical to improving all aspects of heath. Sleep heath disparities are impacted by socio-economic status, racism, discrimination, neighborhood segregation, geography, social patterns and access to healthcare as well as by cultural beliefs necessitating a cultural appropriateness component in any intervention devised for reducing sleep health disparities.

  • How I Do It: Approach to Eosinophilia Presenting with Pulmonary Symptoms
    • Authors: Chen E. Rosenberg; Paneez Khoury
      Abstract: Eosinophilia with pulmonary involvement is characterized by the presence of peripheral blood eosinophilia, typically ≥500 cells/mm3; pulmonary symptoms and physical exam findings, which are nonspecific; radiographic evidence of pulmonary disease; and is further supported by histopathologic evidence of tissue eosinophilia in a lung or pleura biopsy specimen and/or increased eosinophils in bronchoalveolar lavage fluid, usually > 10 percent. Considering that there are a variety of underlying etiologies of eosinophilia with pulmonary manifestations and overlapping clinical, laboratory and radiologic features, it is essential to systematically approach the evaluation of eosinophilia with pulmonary findings.

      Abstract: The COVID-19 pandemic may require rationing of various medical resources if demand exceeds supply. Theoretical frameworks for resource allocation have provided much needed ethical guidance but hospitals still need to address objective practicalities and legal vetting to operationalize scarce resource allocation schemata.To develop operational scarce resource allocation processes for public health catastrophes, including the COVID-19 pandemic, five health systems in Maryland formed a consortium – with diverse expertise and representation – representing more than half of all hospitals in the state.

  • Leadership Essentials for the Chest Physician: Change
    • Authors: James K. Stoller
      Abstract: Change is a fact of life; the absence of change creates stagnation. This is perhaps especially true in healthcare, where progress in treating disease depends on innovation and progress.At the same time, change is often uncomfortable. Thus, it is helpful to model the change process in order to optimize the chances of successfully effecting change. Furthermore, how to lead change is a critical leadership competency.Three models for leading change are reviewed – the first by Kotter, which was not designed for healthcare, the second by Heath and Heath called “switch”, and the third by Silversin and Kornacki, which was uniquely designed for healthcare.

  • “How I Do It”: Building Teams in Healthcare
    • Authors: James K. Stoller
      Abstract: Because teams can accomplish goals that individuals cannot, teams matter. Indeed, teams especially matter in settings like healthcare, where favorable outcomes depend critically on the contributions of many different people with diverse skills. As important as effective teambuilding is for healthcare, how to build teams is often not included in medical curricula and doctors learn to build teams by hidden curricula. In the context that we can do better, this “How I do it” presents an approach to building a team in a common scenario for the chest physician – picking up the inpatient Pulmonary Consult Service.

  • Use of Handheld Point-of-Care Ultrasound in Emergency Airway Management
    • Authors: Daniel R. Austin; Marvin G. Chang, Edward A. Bittner
      Abstract: Emergency airway management (EAM) is associated with a high rate of complications, morbidity and mortality. Handheld point-of-care ultrasound (POCUS) shows promise as an emerging technology to facilitate rapid screening for difficult laryngoscopy, identify the cricothyroid membrane (CTM) for potential cricothyroidotomy, assess for increased aspiration risk, as well as provide confirmation of proper endotracheal tube (ETT) positioning. This review summarizes the available evidence for the use of POCUS in EAM, provides an algorithm to facilitate its incorporation into existing EAM practice to improve patient safety and serve as a framework for future validation studies.

  • The spectrum of sleep disorders in Parkinson’s disease: a review
    • Authors: Lajoie AC; Lafontaine AL, Kaminska M
      Abstract: There is increasing interest in the effects of sleep and sleep disturbances on the brain, particularly in relation to aging and neurodegenerative processes. Parkinson’s disease (PD) is the second most common neurodegenerative disorder, with growing prevalence worldwide. Sleep disorders, including sleep-disordered breathing (SDB), are amongst the most frequent non-motor manifestations of PD. They can substantially impair quality of life, and possibly affect the course of the disease. This article reviews the etiology, implications and management of sleep disturbances in PD, such as excessive daytime sleepiness, insomnia, restless legs syndrome, rapid eye movement sleep behavior disorder and SDB.

  • Leadership Essentials for the Chest Physician: Models, Attributes, and
           Styles
    • Authors: James K. Stoller
      Abstract: In the context that leadership matters and that leadership competencies differ from those needed to practice medicine or conduct research, developing leadership competencies for physicians is important. Indeed, effective leadership is needed ubiquitously in healthcare, both at the executive level and at the bedside, e.g., leading clinical teams and problem-solving on the ward.Various leadership models have been proposed, most converging on common attributes – as described by Kouzes and Posner – of envisioning a new and better future state, inspiring others around this shared vision, empowering others to effect the vision, modeling the expected behaviors, and engaging others by appealing to shared values.

      Abstract: Emotional intelligence (EI) has become widely appreciated as an important leadership attribute, in business, education and, increasingly, in healthcare. Defined as “the capacity to understand your own and others’ emotions and to motivate and develop yourself and others in service of improved work performance and enhanced organizational effectiveness,” EI is correlated with a number of success attributes in several sectors, e.g., in business, enhanced business performance and enhanced personal career success; and in healthcare, with enhanced patient satisfaction, lower burnout, lower litigation risk, and enhanced leadership success.

      Abstract: The coronavirus pandemic has disrupted clinical practice, healthcare organizations, and life. In the context that “a crisis is a terrible thing to waste,” as disruptive as the pandemic has been to traditional practices – both clinically and educationally – opportunities have also presented. Clinical benefits have included the propulsion of clinical innovation, including development of novel vaccines; accelerated understanding of multiplex ventilation, etc. Approaches to educating students and other learners have also changed radically, with suspension of live teaching in most instances and a precipitous transition to virtual instruction.

      Abstract: Upon pneumothorax occurrence in patients with Duchenne muscular dystrophy, recurrences and severe lung damage are common; moreover, they have higher mortality rates than patients without pneumothorax. Chest CT scans should be performed to identify risk factors and treatment should be initiated accordingly. In addition, physicians should consider chest CT even if there is no x-ray abnormality in case of suspected pneumothorax.

      Abstract: Using quantitative CT imaging, we identified three groups of individuals in older ever-smokers that replicate in two cohorts. Airway gene expression differences between the three groups suggests increased levels of inflammation in the most severe clinical phenotype, possibly mediated by the TNF-α and interferon-β pathways.

      Abstract: Random error in real-world pack-year assessments leads to a substantial rate of misclassifying who should be offered CT screening if a > 30 pack-year criterion is used. However, using a lung cancer risk threshold mitigates the impact of unreliable pack-year information. Decision-makers concerned about the impact of unreliable pack year information should consider using risk-based approaches to CT screening.

  • Etoposide as Salvage Therapy for Cytokine Storm due to COVID-19
    • Authors: Maulin Patel; Eduardo Dominguez, Daniel Sacher, Parag Desai, Ashwin Chandar, Michael Bromberg, Roberto Caricchio, Gerard J. Criner, Temple University COVID-19 Research Group
      Abstract: COVID-19 has resulted in significant morbidity and mortality due to lack of effective therapies. Therapeutic strategies under investigation target the overactive cytokine response with anti-cytokine or immunomodulators therapies. We present a unique case of severe cytokine storm resistant to multiple anti-cytokine therapies, but eventually responsive to Etoposide. Thus, Etoposide may have a role as salvage therapy in treatment of cytokine storm in COVID-19. To our knowledge, this is the first reported case of use of Etoposide in COVID-19.

      Abstract: We describe a cluster of beryllium-sensitized workers from a non-beryllium-related industry caused by environmental exposure to beryllium-containing concrete dust, which exhibited markedly elevated beryllium content. Importantly, analyses of dusts from different localities contain markedly different amounts of beryllium. Thus, besides workplace-related exposure, environmental factors are also capable to elicit a beryllium sensitization.

      Abstract: In PH-patients, short-time exposure to hypoxia was well tolerated but reduced CWRET-time compared to normoxia in association with hypoxemia, lactacidemia and hypocapnia. Since pulmonary hemodynamics and dyspnea at end-exercise remained unaltered, the hypoxia-induced exercise limitation may be due to a reduced oxygen delivery causing peripheral tissue hypoxia, augmented lactic acid loading and hyperventilation.

      Abstract: Cardiopulmonary and blood lactate responses during submaximal ECC were less compared to CON at equivalent mechanical workloads in health and COPD, and this was confirmed at a muscle level in COPD. Submaximal ECC was well tolerated and allowed greater mechanical work at lower ventilatory cost. However, in people with COPD, a training intervention based on ECC is unlikely to stimulate cardiovascular and metabolic adaptation to the same extent as CON.

Although the number of screening facilities in the US has increased, screening uptake has been slow. To better understand the slow screening uptake, we evaluated geographic access to screening facilities nationwide.

  • Development of Drugs for Nontuberculous Mycobacterial Disease:
           Clinicians’ Interpretation of a US FDA Workshop
    • Authors: Patrick A. Flume; David E. Griffith, James D. Chalmers, Charles L. Daley, Kenneth Olivier, Anne O’Donnell, Timothy Aksamit, Shannon Kasperbauer, Amy Leitman, Kevin L. Winthrop
      Abstract: The Food & Drug Administration (FDA) convened a workshop to discuss clinical trial design challenges and considerations related to the treatment of non-tuberculous mycobacterial pulmonary disease (NTM-PD), to include topics such as clinical trial endpoints, duration, and populations. Here the clinicians participating in the meeting provide their interpretation of the discussion, which included FDA and industry representatives. The treatment of NTM-PD typically includes multiple antibiotics for a prolonged period, can be difficult to tolerate, and there is great need for new treatment options.

  • A fluid challenge test for the diagnosis of occult heart failure
    • Authors: Michele D'Alto; David Badesch, Eduardo Bossone, Barry A. Borlaug, Evan Brittain, Marc Humbert, Robert Naeije
      Abstract: A right heart catheterization with measurements of pulmonary artery wedge pressure (PAWP) may be necessary for the diagnosis of left heart failure as a cause of pulmonary hypertension or unexplained dyspnea. Diagnostic cut-off values are a PAWP of ≥ 15 mmHg at rest a PAWP of ≥ 25 mmHg during exercise. However, accurate measurement of PAWP can be challenging and heart failure may be occult. A left heart catheterization, with measurement of left ventricular end-diastolic pressure, may also be indecisive.

      Abstract: In this cohort of community-dwelling adults not selected on the basis of lung disease, more severe vascular pruning on CT was associated with greater odds of ILA, ILA progression, and restrictive pattern on spirometry. Pruning on CT may be an indicator of early pulmonary vasculopathy associated with interstitial lung disease.

      Abstract: DAD, the histologic correlate of ARDS, is the predominant histopathologic pattern identified in lung pathology from patients with COVID-19, H1N1 influenza and SARS. Microthrombi were reported more frequently in both patients with COVID-19 and SARS as compared to H1N1 influenza. Future work is needed to validate this histopathologic finding and, if confirmed, elucidate the mechanistic underpinnings and characterize any associations with clinically important outcomes.

    • Authors: Gemma E. Stanford; Kavita Dave, Nicholas J. Simmonds
      First page: 93
      Abstract: Pulmonary exacerbations (PEx) are significant life events in people with cystic fibrosis (CF), associated with declining lung function, reduced quality of life (QoL), hospitalisations and decreased survival. The adult CF population is increasing worldwide, with many patients surviving prolonged periods with severe multi-morbid disease. In many countries the number of adults with CF exceeds the number of children, and PEx are particularly burdensome for adults as they tend to require longer courses and more intravenous treatment than children.

      Abstract: Comorbidities significantly contribute to morbidity, mortality, and health care costs in individuals with chronic obstructive pulmonary disease (COPD). Comorbidity prevalence does not always correlate with lung disease severity and the elevated risk of certain comorbidities is often independent of shared risk factors such as tobacco burden. While COPD management guidelines recognize the importance of identifying and treating comorbidities as part of the comprehensive management of COPD patients, little guidance is provided regarding best screening practices.

  • The Thousand Faces of Leptin in the Lung
    • Authors: Etienne-Marie Jutant; Ly Tu, Marc Humbert, Christophe guignabert, Alice Huertas
      First page: 239
      Abstract: Leptin is a pleotropic hormone known to regulate a wide range of systemic functions, from satiety to inflammation. Increasing evidence has shown that leptin and its receptor, ObR, are not only expressed in adipose tissue but also in several organs, including the lungs. Leptin levels were first believed to only be elevated in the lungs of obese patients and it was suspected to be responsible for obesity-related lung complications. Aside from obesity, leptin displays many faces in the respiratory system, independently of body weight, as this cytokine-like hormone plays important physiological roles, from the embryogenic state to maturation of the lungs and the control of ventilation.

    • Authors: Pamela Laird; Roz Walker, Mary Lane B.Nur, James Totterdell, Anne Chang, André Schultz
      First page: 249
      Abstract: Health seeking for children with chronic wet cough can be facilitated through provision of culturally secure health information. Clinician proficiency in the management of PBB can be improved with KT strategies which include training in culturally informed management, leading to better health outcomes. Comprehensive strategies that include both families and health systems are required to ensure that chronic wet cough in children is detected and optimally managed.

  • “How to Review Post-lobectomy Posteroanterior Chest
           Radiographs”
    • Authors: Jeong Min Ko; Min Kyung Jung, Hyun Jin Park
      First page: 294
      Abstract: Lung cancer is currently the most common malignancy in the world. A lobectomy is the gold standard of care for most patients with an operable lung cancer and accounts for 60-70% of lung resection. The chest radiograph may appear normal after a lobectomy, particularly in uncomplicated cases. However, lobectomy usually leaves the surgical staples at the bronchial stump and causes various changes in the intra- and extrapulmonary thoracic structures on plain radiographs. These changes may differ according to the resected lobe.

      Abstract: Group 1 PAH patients remain predominately middle-aged women diagnosed with IPAH or APAH. Delays in diagnosis of PAH persist. Treatment with combinations of PAH targeted medications are more common than in the past. Women often report pregnancy complications, as well as exposure to anorexigens, oral contraceptives, and/or recreational drugs. Genetic tests frequently identify unsuspected HPAH.

  • How I Do It: The PERT Concept: A Step-by-Step Approach to Managing PE
    • Authors: Belinda N. Rivera-Lebron; Parth M. Rali, Victor F. Tapson
      First page: 347
      Abstract: Pulmonary embolism (PE) is a major source of morbidity and mortality. The presentation of acute PE varies, ranging from few or no symptoms to sudden death. Patient outcome depends upon how well the right ventricle can sustain the increased afterload caused by the embolic burden. Careful risk stratification is critical and the pulmonary embolism response team (PERT) concept offers a rapid and multidisciplinary approach. Anticoagulation is essential unless contraindicated; thrombolysis, surgical embolectomy, and catheter-directed approaches are also available.

      First page: 413
      Abstract: Those responsible for developing and managing SDM-LCS programs voiced concerns regarding both patient access and SDM quality, regardless of organizational context, or LCS-SDM model implemented. The challenge facing these organizations, and those wanting to help patients and clinicians balance the tradeoffs inherent with LCS, is how to move beyond a “check box” documentation requirement to a process that enables LCS to be offered to all high risk patients, but used only by those who are informed and for whom screening represents a value concordant service.
