      Abstract: A 78-year-old man with asthma and COPD presented with shortness of breath, cough, and severe malaise for 4 days. Upon arrival, the patient was conscious and body temperature was 37.5°C. Arterial oxygen saturation (Spo2) was 80% on room air. Laboratory data demonstrated a WBC count of 17,400/μL (89.5% neutrophils) and C-reactive protein of 5.00 mg/dL. CT scan of chest revealed scattered ground-glass in the upper right lobe and thickening of the bronchial wall. Based on these findings, acute bronchopneumonia was diagnosed and antibacterial therapy was started.

      Abstract: A 38-year-old male with a prior diagnosis of severe OSA (apnea-hypopnea index [AHI] 99/h) presented for transfer of care. He was successfully titrated to CPAP of 10 cm H2O at an outside laboratory and was compliant with therapy with residual AHI 1.9/h. On presentation, he was polycythemic, with negative evaluation for primary polycythemia, and evaluation for hypoxemia was initiated.

  • A Woman With Dyspnea, Weight Loss, and Splenic Lesions
    • Authors: Jennifer S. Hanberg; Dana Dunne
      Abstract: The patient is a 37-year-old hospital employee and current smoker with a 10 pack-year smoking history, who presented with dyspnea, chest pain, and weight loss. She was in her usual state of health until 4 months prior to admission when she developed intermittent left-sided chest pain, cough productive of scant yellow sputum, fevers, and anorexia. Initial chest radiograph was normal and her outpatient physician prescribed azithromycin, which she took without improvement. One month prior to admission, a follow-up chest radiograph revealed a left-sided upper lobe consolidation; she received a course of levofloxacin without improvement.

    • Authors: Patrick Duncan; Stephanie Cull, Palmi Shah, Amie Gamino
      Abstract: A 59-year-old man presented to the ED with a chief complaint of shortness of breath. His past medical history was significant for end-stage renal disease secondary to lithium toxicity, immunosuppression subsequent to cadaveric renal transplantation, bipolar disorder, and hypertension. His shortness of breath had begun 6 months previously and was initially intermittent; it then progressed to constant shortness of breath over the few weeks before presentation. He had no fever, hemoptysis, or chest pain.

      Abstract: A 64-year-old man presented for consideration for lung transplant. He had a history of previous tobacco use, OSA on CPAP therapy, and gastroesophageal reflux disease. He worked as a design engineer. The patient had a 4-year history of dyspnea on exertion, followed with periodic CT scan of the chest. Nine months prior to his evaluation for lung transplant, the patient developed worsening of dyspnea, dry cough, poor appetite, and weight loss. At times, the cough was violent and associated with chest pressure.

  • Lung Ultrasound for the Diagnosis of Acute Heart Failure in the ED
    • Authors: Philippe Le Conte; François Javaudin
      Pages: 3 - 4
      Abstract: Despite advances, diagnosis of acute heart failure (AHF) in the ED remains challenging, especially in elderly patients presenting with symptoms of acute respiratory failure. However, initial diagnostic accuracy is pivotal to avoid inappropriate therapy that could worsen outcome. In a prospective observational survey including 514 elderly patients, Ray et al1 reported that misdiagnosis and subsequent inappropriate treatment resulted in a doubling of the OR for in-hospital mortality. Clinical findings are limited, as bilateral crackles have a positive likelihood ratio of only 4.

  • Taking the Air Out of Nebulized Lidocaine
    • Authors: Emily DuComb; C. Matthew Kinsey
      Pages: 5 - 6
      Abstract: Flexible bronchoscopy is widely used for the diagnosis of various pulmonary conditions. Although it can be performed with topical analgesia alone, use of sedation improves patient tolerance of the procedure and working conditions for the bronchoscopist and is recommended unless contraindications exist.1 Adjunctive topical anesthesia with lidocaine is useful to improve cough and can reduce the amount of sedation required. This can be administered by various methods, including intranasally, inhaled via nebulization, sprayed into the oropharynx, injected transtracheally, and administered locally via the bronchoscope.

  • POINT: Can Screening for COPD Improve Outcomes' Yes
    • Authors: Barbara P. Yawn; Fernando J. Martinez
      Pages: 7 - 9
      Abstract: COPD is a common but often underrecognized and underdiagnosed condition, especially in primary care settings in the United States.1 Despite being the fourth leading cause of death in the United States, both diagnosed and undiagnosed COPD are a major cause of morbidity, mortality, disability, hospitalizations, and health-care expenditures.2 The slow decline in lung function and compensatory activity limitation often results in failure of symptom reporting to clinicians, with patients attributing symptoms to aging, obesity, poor conditioning, or “smoker’s cough.” Primary care physicians also fail to query regarding chronic respiratory symptoms or note recurrent respiratory events as significant, leaving these patients to appear to be “asymptomatic.”

  • COUNTERPOINT: Can Screening for COPD Improve Outcomes' No
    • Authors: David M. Mannino; Byron Thomashow
      Pages: 9 - 12
      Abstract: In 2016, the US Preventive Services Task Force (USPSTF) “did not find evidence that screening for COPD in asymptomatic persons improves health-related quality of life, morbidity, or mortality.”1 The Task Force also concluded that early detection of COPD does not alter the course of disease or improve patient outcomes.1 The thought process underlying this decision could be summarized as follows: the only known intervention shown to change the natural history of COPD is smoking cessation; there is no evidence that knowledge of a COPD diagnosis increases the likelihood of smoking cessation; every smoker should stop smoking; thus there is no rationale to screen for COPD (particularly in a person who has no symptoms).

      Abstract: We read with great interest Drs Mannino and Thomashow’s discussion of COPD screening for asymptomatic individuals1 and agree it provides limited ability to identify, prevent, or treat COPD before symptoms appear. Indeed, smoking cessation and prevention remain key to disease prevention and progression.

    • Authors: David M. Mannino; Byron Thomashow
      Pages: 14 - 15
      Abstract: In their argument supporting the idea that screening for COPD can improve outcomes, Drs Yawn and Martinez1 argue that “COPD screening must develop better, more symptom-based tools and appropriate follow-up support.” We certainly agree with that conclusion and hope that CAPTURE (COPD Assessment in Primary Care to Identify Undiagnosed Respiratory Disease and Exacerbation Risk) will lead to earlier diagnosis and earlier therapy.2 However, even if the ongoing study attempting to validate the utility of this tool in primary care confirms earlier results without disrupting practice patterns,3 the patients identified will be symptomatic but will not have received a diagnosis.

  • Can qSOFA Perform Better If Combined With Frailty Measures in Elderly
    • Authors: Kevin K.C. Hung; Ling Yan Leung, Joseph Walline, Colin A. Graham
      First page: 231
      Abstract: In the recently published study in CHEST (August 2019) by Anand et al,1 involving> 1 million adults admitted to 85 US hospitals, the major findings, that the Quick Sequential Organ Failure Assessment (qSOFA) has both low sensitivity for identifying suspected infection or sepsis and its prognostic significance is not specific to infection, are not surprising. We agree that the qSOFA has limited utility in the screening and diagnosis of sepsis. There remains a pressing need to develop new screening tools that are both sensitive and specific for sepsis.

      Abstract: We thank Hung et al for their interest in our article1 and their ongoing contributions to understanding the strengths and limitations of the Quick Sequential Organ Failure Assessment (qSOFA). We agree that the performance of the qSOFA in elderly patients with frailty is an important topic of investigation. We would point out that the two studies cited by Hung et al on this issue had somewhat mixed findings. Although Fernando et al2 demonstrated particularly high mortality in patients who were critically ill with both the qSOFA and frailty, Bastoni et al3 found that the prognostic accuracy of the qSOFA was poor in a geriatric acute care setting and comparable with the Systemic Inflammatory Response Syndrome criteria.

  • Dear qSOFA, We Would Like to Get to Know You Better…
    • Authors: Stephanie Parks Taylor; Marc Kowalkowski
      Pages: 232 - 233
      Abstract: In the August issue of CHEST, Anand et al1 use a large clinical and administrative dataset to evaluate the “appropriate role of qSOFA [quick Sequential Organ Failure Assessment] in sepsis screening, diagnosis, and triggering of empiric antibiotics.” Although the well-designed and executed study has many strengths, we wonder if the conclusions of the authors and the breakup letter penned by the accompanying editorial2 could be premature. The ultimate goal of predictive analytics is to improve decision-making, and the ultimate measure of a prognostic score’s usefulness is whether its use improves outcomes for patients.

      Abstract: We thank Drs Taylor and Kowalkowski for their thoughtful letter and interest in our article.1 We agree that statistical performance should not be the sole criterion by which a sepsis screening or diagnostic strategy should be evaluated. We also agree that the ultimate measure of the relative value of a sepsis-screening system is whether real-world application leads to better outcomes for patients. Unfortunately, to our knowledge, a prospective comparative evaluation of various screening strategies, including quick Sequential Organ Failure Assessment (qSOFA) vs the systemic inflammatory response syndrome (SIRS) criteria, has not yet been published.

      Abstract: While researching an article on the social and legal complexities of “brain death,” I came across the literature review in CHEST (October 2014) by Miller et al.1 In that article (bottom of page 1094), Miller et al wrote “Pope Benedict XVI subsequently expanded on this by stating:” followed by two block quotes (page 1095). The authors also wrote, “Additionally, he stated:” between the two block quotes.

      Abstract: We thank Dr Nguyen for his thoughtful comments on our 2014 article on brain death and Islam.1 Although not the focus of the article, we address his comments regarding Catholicism. The loss of integration view has since predominated in Christianity since accepted as doctrine by the Council of Vienne (1312 ad). Pope Pius X stated that the specification of biological parameters indicating that death has occurred “does not fall within the competence of the Church.”2 Rather, it pertains to the responsibility and competence of the medical profession to judge and establish the signs that serve as reliable indicators that death has occurred with adequate moral certainty.

  • Lung Cancer Screening Uptake in the United States
    • Authors: Patrick C. Yong; Keith Sigel, Sadiq Rehmani, Juan Wisnivesky, Minal S. Kale
      Pages: 236 - 238
      Abstract: The United States Preventive Services Task Force (USPSTF) guidelines recommend yearly low-dose CT (LDCT) screening for high-risk smokers. These guidelines are based on the National Lung Screening Trial (NLST), which showed that yearly LDCT screening for high-risk smokers decreased lung cancer-related mortality.1 Despite strong supporting evidence, national data indicate low screening uptake, with < 6% of USPSTF criteria-eligible smokers being screened in 2015.2 However, it is unclear if screening uptake is increasing, and very little is known about predictors of screening uptake.

      Abstract: The term interstitial pneumonia with autoimmune features (IPAF) defines patients with interstitial lung disease (ILD) with some autoimmune characteristics that are insufficient to fulfill classification criteria for a specific connective tissue disease (CTD).1 IPAF classification comprises several items subdivided into clinical, serological, and morphological domains. Patients with a radiological or histological pattern of usual interstitial pneumonia (UIP) need at least one item from both the clinical and serological domains, whereas patients with other ILD patterns can be classified as IPAF even with only one item.

           identifies poor asthma control with greater sensitivity than spirometry
    • Authors: Alice M. Cottee; Leigh M. Seccombe, Cindy Thamrin, Gregory G. King, Matthew J. Peters, Claude S. Farah
      Abstract: Persistent bronchodilator response (BDR) following diagnosis of asthma is an under-recognized treatable trait, associated with worse lung function and asthma control. The forced oscillation technique (FOT) measures respiratory system impedance and BDR cutoffs have been proposed for healthy adults, however relevance in asthma is unknown. We compared BDR cutoffs using FOT and spirometry in asthma and the relationship with asthma control.

      Abstract: Chronic obstructive pulmonary disease (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.

           in Chronic Obstructive Pulmonary Disease.
    • Authors: Masashi Kanezaki; Kunihiko Terada, Satoru Ebihara
      Abstract: Inhalation of L-menthol as a Transient Receptor Potential Melastatin 8 agonist induces a cooling sensation in the airway. This cooling sensation induced through olfactory stimulation by L-menthol (OSM) alleviates dyspnea in healthy humans. Therefore, we investigated effects of OSM on the neural respiratory drive (NRD) and multidimensional aspects of dyspnea induced by inspiratory resistive loaded breathing in chronic obstructive pulmonary disease (COPD).

      Abstract: Parasitosis 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 radiological manifestations, which often makes it a diagnostic challenge. 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 pathobiological consequences of CSA/HSCB eventually lead to sustained sympathetic over-activity, repeated hospitalization, and premature mortality. 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 positive airway pressure (PAP) therapy, both continuous PAP (CPAP) and Adaptive servo ventilation (ASV) devices.

Prior studies have suggested that digital drainage systems permit a 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 following pulmonary surgery and spontaneous pneumothorax.

      Abstract: Chronic hypersensitivity pneumonitis (CHP) is an immune mediated interstitial lung disease, 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.

      Abstract: Severe pulmonary hypertension (PH) in patients with aortic stenosis is related to poor prognosis after 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≤2.8m/s), “intermediate” (TRV 2.9-3.4m/s) and “high” (TRV>3.4m/s). Right ventricle (RV) is an important determinant of prognosis in PH. Our aim was to analyze the value of right atrial area>18cm2 and RV/left ventricle ratio>1 in the long-term prognosis after AVR, mainly in the “intermediate” group.

The COPDGene study, which has generated ten-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 we summarize the main COPD subtype findings from COPDGene.

    • 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, due to the nature of critical illness, sleep has not been considered a priority for patient care in the intensive care unit. More recently, research has demonstrated that sleep is markedly abnormal in critically ill patients. 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, 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, healthy food stores), neighborhood deprivation (disadvantage, disorder), and the social environment (social cohesion, safety, stigma) with sleep in both adult and pediatric populations.

    • Authors: Hongbin Wang; Lina Wu, Xilin Sun
      Abstract: Accurate diagnosis is crucial for improving 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 to 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.

  • Comparing the Effectiveness and Safety of Non-Vitamin K Antagonist Oral
           Anticoagulants and Warfarin in the Elderly Asian Patients with Atrial
           Fibrillation: A Nationwide Cohort Study
    • Authors: Tze-Fan Chao; Chern-En Chiang, Jo-Nan Liao, Tzeng-Ji Chen, Gregory Y.H. Lip, Shih-Ann Chen
      Abstract: Stroke prevention in elderly patients with atrial fibrillation (AF) can be challenging, requiring a balance between thromboembolism prevention and serious bleeding. Comparisons of non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin in the elderly, at different age strata (age 65-74, 75-89, ≥90) in the daily practice have not been well described, particularly in Asians. We aimed to assess the clinical outcomes of NOACs compared to warfarin for stroke prevention in elderly patients with AF.

    • Authors: Daniel M. DePietro; Nicole R. Curnes, Jesse Chittams, Victor A. Ferrari, Reed E. Pyeritz, Scott O. Trerotola
      Abstract: High-resolution chest CT (HRCT) is recommended after PAVM embolotherapy to assess for PAVM persistence and untreated PAVM growth. Graded transthoracic contrast echocardiography (TTCE) predicts need for embolotherapy in PAVM screening. This study sought to determine whether post-embolotherapy graded TTCE can similarly predict need for repeat embolotherapy.

  • Is mortality a useful primary endpoint for critical care trials'
    • Authors: Richard A. Veldhoen; Daniel Howes, David M. Maslove
      Abstract: Mortality has long been used as a primary endpoint for randomized controlled trials in critical care. Recently, a plurality of trials targeting mortality endpoints as their primary outcome have 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 towards a neutral result, as well as reasons to consider alternative endpoints that are better coupled to the expected therapeutic effect.

    • Authors: Elizabeth T. McCormick; Christian Escobar, Ania Wajnberg, Elizabeth T. McCormick
      Abstract: As the population ages, and more patients with chronic pulmonary diseases become frail and functionally impaired, the prevalence of homebound patients grows. Homebound patients have higher disease burden, inpatient utilization rates, and mortality than non- homebound patients. Vulnerable homebound patients with pulmonary disease benefit from pulmonary expertise to evaluate and optimize their complex medication regimens, evaluate equipment such as nebulizers, home oxygen, ventilators and suction machines, and coordinate services.

      Abstract: Chronic lung disease accounts for a significant global burden with respect to death, disability and healthcare 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: 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 chronic obstructive pulmonary disease (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: 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 peri-procedural outcomes of elective intubation in the operating room when compared to emergency intubation in the intensive care unit (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 will provide an updated framework for airway assessment before direct laryngoscopy (DL) and video laryngoscopy (VL), utilization 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: 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.

  • Recent Advances in Severe Asthma: from Phenotypes to Personalized Medicine
    • Authors: Nathan Schoettler; Mary E. Strek
      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: While there is ongoing debate about the impact of early postnatal exposure to antibiotics on the development of asthma, the possibility that antibiotic exposure may impair lung function has not previously been examined. Furthermore, it is not clear if specific types of antibiotics may have a greater effect, or if children with genetic mutations in the oxidative stress response glutathione S-transferase (GST) superfamily may be at greater risk.

  • Better with Ultrasound: Arterial Line Placement
    • Authors: Ann Wang; Ariel Hendin, Scott J. Millington, Seth Koenig, Lewis A. Eisen, Ariel L. Shiloh
      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.

      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.

           opportunity for precision medicine
    • Authors: Andrey Zinchuk; Henry K. Yaggi
      Abstract: Current strategies for management of obstructive sleep apnea (OSA) reflect a one-size-fits-all approach. Diagnosis and severity of OSA are based on the apnea hypopnea index and treatment initiated with continuous positive airway pressure (CPAP), followed by trials of alternatives, such as oral appliances, if CPAP “fails.” This approach does not consider heterogeneity of individuals with OSA, reflected by varying risk factors, pathophysiological causes, clinical manifestations and consequences. Recently, studies using analytic approaches such as cluster analysis have taken advantage of this heterogeneity to identify OSA phenotypes, or sub-types of patients with unique characteristics, that may enable more personalized approaches to prognostication and treatment.

      Abstract: Classically, mitochondria have largely been thought to influence the development of illness by modulating cell metabolism and determining the rate of production of high energy phosphate compounds (e.g. ATP). It is now recognized that this is a simplistic view and that mitochondria play key roles in many other processes, including cell signaling, regulating gene expression, modulating cellular calcium levels and influencing the activation of cell death pathways (e.g. caspase activation). Moreover, these multiple mitochondrial functional characteristics are now known to influence the evolution of cellular and organ function in many disease states, including sepsis, ICU acquired skeletal muscle dysfunction, acute lung injury, acute renal failure, and critical illness related immune function dysregulation.

Bronchoscopic electrosurgical and laser ablative tools have proven to be safe and effective instruments for the treatment of malignant CAO. While therapeutic modalities such as electrocautery, argon plasma coagulation (APC), and laser have been utilized for decades, additional tools including radiofrequency ablation (RFA) catheters continue to be developed for the treatment of CAO. These modalities are considered safe in the hands of experienced operators, though serious complications can occur.

Most of cART-treated patients ageing with controlled HIV replication are nowadays admitted to the intensive care unit (ICU) for non-AIDS-related events, mostly bacterial pneumonia and exacerbation of comorbidities, variably impacted by chronic HIV infection – e.g., chronic obstructive pulmonary disease, cardiovascular diseases, or solid neoplasms.

  • Eligibility for Lung Volume Reduction Surgery in Chronic Obstructive
           Pulmonary Disease patients identified in a UK primary care setting
    • Authors: H. Whittaker; O. Connell, J. Campbell, A.F. Elbehairy, N.S. Hopkinson, J.K. Quint
      Abstract: Although lung volume reduction surgery (LVRS) improves survival in appropriately selected patients with Chronic Obstructive Pulmonary Disease (COPD), few procedures are performed. The National Institute for Clinical and Healthcare Excellence recently recommended a more systematic approach to identifying potential candidates. We investigated LVRS referrals from a UK primary care population and aimed to establish an accurate estimate of eligible patients and determine a strategy for identifying potential candidates systematically.

  • Apneas of Heart Failure and Phenotype-Guided Treatments Part One:
           Obstructive Sleep Apnea
    • Authors: Shahrokh Javaheri; Lee K. Brown, William T. Abraham, Rami Khayat
      Abstract: Sleep-disordered breathing (SDB), including obstructive and central sleep apnea (OSA and CSA), is highly prevalent in patients with heart failure (HF). Multiple studies have shown this high prevalence in asymptomatic as well as symptomatic patients with reduced left ventricular ejection fraction (HFrEF), as well as those with preserved ejection fraction (HFpEF).The acute pathobiological consequences of OSA including exaggerated sympathetic activity, oxidative stress, and inflammation, eventually could lead to progressive left ventricular dysfunction, repeated hospitalization, and excessive mortality.

  • Meeting the Challenge of Identifying New Treatments for Type 2-low
           Neutrophilic Asthma
    • Authors: Or Kalchiem-Dekel; Xianglan Yao, Stewart J. Levine
      First page: 26
      Abstract: Asthma pathobiology can be broadly classified by endotypes of type 2-high and type 2-low disease, with a significant percentage of asthmatics having a type 2-low endotype that is poorly responsive to the anti-inflammatory actions of corticosteroids. Therapeutic approaches that target mediators of type 2-low asthma with neutrophilic airway inflammation have yet to enter clinical practice. Therefore, an unmet need exists for the development of new treatments for patients with a neutrophilic asthma, especially those with severe disease.

      Abstract: After hospitalization for community-acquired pneumonia (CAP), patients’ clinical course may progress to clinical improvement, clinical failure, or non-resolving pneumonia. The epidemiology and outcomes of patients with CAP according to clinical course has not been well-studied. The objective of this study was to characterize the incidence and outcomes for each clinical course of hospitalized patients with CAP.

      Abstract: Multiple studies have identified COPD subtypes using visual or quantitative evaluation of CT images. However, there has been no systematic assessment of a combined visual and quantitative CT classification. We integrated visually defined patterns of emphysema with quantitative imaging features and spirometry data to produce a set of ten non-overlapping CT subtypes, and we assessed differences between subtypes in demographic features, physiology, longitudinal disease progression, and mortality.

      Abstract: Admissions to intensive care unit (ICU) related to alcohol, prescription and illicit drugs shown to be widespread and costly. In 1993, study by Baldwin et al. revealed 28% of ICU admissions at Johns Hopkins Hospital related to substance abuse and accrued 39% costs. Since then, healthcare expenditures have increased, and substance abuse treatment admissions have risen. We conducted a study to provide updated data on ICU utilization and costs related to licit and illicit abuse at a large county hospital in Indianapolis, Indiana.

      Abstract: Critically ill patients who develop the acute respiratory distress syndrome (ARDS) have substantial associated morbidity and mortality. Circulating mitochondrial DNA (mtDNA) released during critical illness causes endothelial dysfunction and lung injury in experimental models. We hypothesized that elevated plasma mtDNA is associated with ARDS in critically ill trauma and sepsis patients.

  • Managing Massive Hemoptysis
    • Authors: Kevin Davidson; Samira Shojaee
      First page: 77
      Abstract: Massive hemoptysis is a medical emergency with high mortality presenting several difficult diagnostic and therapeutic challenges. The origin of bleeding and underlying etiology often is not immediately apparent and techniques for management of this dangerous condition necessitate an expedient response. Unlike hemorrhage in other circumstances, a small amount of blood can rapidly flood the airways thereby impairing oxygenation and ventilation leading to asphyxia and consequent cardiovascular collapse.

      Abstract: Patients with interstitial lung disease (ILD) may develop pulmonary hypertension (PH), often disproportionate to ILD severity. Right ventricle to left ventricle diameter ratio (RV:LV) measured at CT pulmonary angiography (CTPA), has been shown to provide valuable information in pulmonary arterial hypertension patients and to predict death or deterioration in acute pulmonary embolism.

      Abstract: Areas of diminished lung density are frequently identified both on routine chest radiographs and chest CT examinations. Colloquially referred to as “hyperlucent” foci of lung, a broad range of underlying pathophysiologic mechanisms and differential diagnoses account for these changes. Despite this, the spectrum of etiologies can be categorized into underlying parenchymal, airway and vascular related entities, respectively. The purpose of this review is to provide a practical diagnostic algorithmic approach to pulmonary hyperlucencies incorporating clinical history and characteristic imaging patterns to narrow the differential.

      First page: 142
      Abstract: Transcranial Doppler (TCD) ultrasound is a non-invasive method of obtaining bedside neurologic information that can supplement the physical examination. In critical care, this can be of particular value in the unconscious patient with an equivocal neurologic exam, as TCD findings can help the clinician in decisions related to more definitive imaging studies as well as potential clinical interventions. Though TCD is traditionally the domain of sonographers and radiologists, there is increasing adoption of goal-directed TCD at the bedside in the critical care environment.

      Abstract: At the recent 6th World Symposium on Pulmonary Hypertension (PH), the definition of PH was redefined to include lower pulmonary artery pressures in the setting of an elevated pulmonary vascular resistance (PVR). However, the relevance of this change to subjects with PH due to left heart disease as well as the pre-operative assessment of heart transplant (HT) recipients is unknown.

      Abstract: Pulmonary arterial hypertension (PAH) prognosis has improved with targeted therapies although the long-term outlook remains poor. Objective multi-parametric risk assessment is recommended to identify patients at risk of early morbidity and mortality, and for optimization of treatment. The REVEAL 2.0 Risk Score is a new model proposed for the follow-up of PAH patients but has not been externally validated.

      Abstract: Positive airway pressure (PAP) and upper airway stimulation (UAS) are approved obstructive sleep apnea (OSA) treatment options.. Although the effect of PAP on improvement in blood pressure (BP) and daytime sleepiness (defined by Epworth Sleepiness Scale, ESS) has been established, the impact of UAS on BP remains unclear. We hypothesize that PAP and UAS will confer improvements in BP and daytime sleepiness.

      First page: 223
      Abstract: Pleural biopsy using either video-assisted thoracoscopic surgery or medical pleuroscopy is the current diagnostic gold standard for pleural pathology with a high, yet imperfect, diagnostic yield. Cryobiopsy may provide greater tissue, increase depth of sampled tissue, and/or reduce crush artifact. However, its impact on diagnostic yield remains uncertain and there are potential concerns regarding its safety too. We performed a systematic review and meta-analysis in order to investigate the same.
