Abstract
Amyloidosis is a disease caused by misfolded proteins that deposit in the extracellular matrix as fibrils, resulting in the dysfunction of the involved organ. The lung is a common target of Amyloidosis, but pulmonary amyloidosis is uncommonly diagnosed since it is rarely symptomatic. Diagnosis of pulmonary amyloidosis is usually made in the setting of systemic amyloidosis, however in cases of localized pulmonary disease, surgical or transbronchial tissue biopsy might be indicated. Pulmonary amyloidosis can be present in a variety of discrete entities. Diffuse Alveolar septal amyloidosis is the most common type and is usually associated with systemic AL amyloidosis. Depending on the degree of the interstitial involvement, it may affect alveolar gas exchange and cause respiratory symptoms. Localized pulmonary Amyloidosis can present as Nodular, Cystic or Tracheobronchial Amyloidosis which may cause symptoms of airway obstruction and large airway stenosis. Pleural effusions, mediastinal lymphadenopathy and pulmonary hypertension has also been reported. Treatment of all types of pulmonary amyloidosis depends on the type of precursor protein, organ involvement and distribution of the disease. Most of the cases are asymptomatic and require only close monitoring. Diffuse alveolar septal amyloidosis treatment follows the treatment of underlying systemic amyloidosis. Tracheobronchial amyloidosis is usually treated with bronchoscopic interventions including debulking and stenting or with external beam radiation. Long-term prognosis of pulmonary amyloidosis usually depends on the type of lung involvement and other organ function.

Abstract
BACKGROUND Major psychiatric disorders are associated with lower life expectancy primarily due to comorbid illnesses and suboptimal access to health care. Large-scale contemporary data in the United States on in-hospital mortality of patients with major psychiatric disorder and sepsis are lacking. OBJECTIVE To describe the short-term outcomes of hospitalized patients with major psychiatric disorders and septic shock. METHODS We performed a retrospective cohort study using the National Inpatient Sample database from 2016 to 2019 to identify septic shock hospitalizations in patients with versus without major psychiatric disorder (defined as schizophrenia and affective disorders). Baseline variables and in-hospital mortality trends were compared between the 2 groups. RESULTS Out of 1,653,255 hospitalizations with septic shock identified between 2016 and 2019, 16.2% had a diagnosis of major psychiatric disorder as defined above. After adjusting for various patient-level and hospital-level demographics and coexisting clinical conditions in a multivariable logistic regression, the odds of in-hospital mortality in patients with any major psychiatric disorder were 0.71 times that of those without a diagnosis of psychiatric illness (95% confidence interval [CI], 0.69-0.73; P < 0.001). Similarly, when the disorders were divided into 2 categories for subanalysis, those with schizophrenia had 38% lower odds of dying compared to those without schizophrenia (adjusted odds ratio, 0.62; 95% CI, 0.58-0.66; P < 0.001). Those with affective disorders had 25% lower odds of in-hospital mortality than those without a diagnosis of an affective disorder (adjusted odds ratio, 0.75; 95% CI, 0.73-0.77; P < 0.001). The adjusted mean length of stay for those diagnosed with major psychiatric disorder was 0.38 days longer than those without significant psychiatric illness (95% CI, 0.28-0.49; P < 0.001). On the other hand, the mean hospitalization charges were $10,516 less for patients with a major psychiatric disorder compared to those without (95% CI, -$11,830 to -$9,201; P < 0.001). CONCLUSIONS Hospitalized patients with major psychiatric disorder and septic shock had lower risk of short-term mortality. Further studies are needed to examine the reasons behind this lower in-hospital mortality risk.

Invasive Pulmonary Aspergillosis in Hospitalized Hematopoietic Stem Cell Transplantation Recipients: Outcomes Based on the United States National Readmission Database. Hematol Oncol Stem Cell Ther 2023; 17:43-50. [PMID: 37581459 DOI: 10.56875/2589-0646.1109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 04/11/2023] [Indexed: 08/16/2023] [Imported: 09/15/2023] Open
Abstract
BACKGROUND AND OBJECTIVE Hematopoietic stem cell transplant (HSCT) is a well-established treatment for hematologic malignancies and certain autoimmune and congenital conditions. HSCT is associated with immunocompromise and increased risk of infections. This study assessed whether invasive pulmonary aspergillosis (IPA) affects in-hospital mortality and 30-day readmission among HSCT patients. A secondary objective was to examine potential differences in complications between HSCT with and without IPA. MATERIALS AND METHODS A retrospective study of a nationally representative cohort of hospital admissions was conducted, with data collected from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project Nationwide Readmissions Database between 2013 and 2019. The International Classification of Diseases, 10th revision (ICD-10), and 9th revision (ICD-9) diagnostic codes were used to identify patients with IPA and HSCT. All adult patients ≥18 years were included in the study. RESULTS There were 90,451 hospitalizations for HSCT from 2013 to 2019; 89,331 (98.8%) had HSCT without IPA, while 1092 (1.2%) hospitalizations had HSCT with IPA. The in-hospital mortality for HSCT-IPA was higher compared to HSCT without IPA (18.3% vs. 4.2%; p < 0.001). HSCT-IPA had a significantly higher 30-day readmission rate (36.2%) than that of HSCT without IPA (24.0%). HSCT-IPA also had a higher mean cost of admission ($303,437) than that of HSCT without IPA ($57,587).The HSCT-IPA group had higher multi-organ complications, including respiratory failure (51.3% vs. 13.5%, p < 0.001), sepsis (38.2% vs. 18.5%, p < 0.001), septic shock (16.1% vs. 5.1%, p < 0.001), need for mechanical ventilation (21.1% vs. 5.1% p < 0.001), non-invasive positive pressure ventilation (4.9% vs. 2.5%, p < 0.001), and intensive-care unit admission (21.8% vs. 6.1% p < 0.001). CONCLUSION IPA is a rare but severe complication associated with HSCT, with higher in-hospital mortality, complications due to multi-organ failure, readmission rates, and cost of hospitalization when compared to HSCT without IPA.

Abstract
Fusarium species manifests as an opportunistic infection with intrinsic resistance to most antifungals. We present a case of a 63-year-old male with myelodysplasia who received allogeneic stem cell transplantation and presented with endophthalmitis as the initial manifestation of invasive fusariosis that progressed to a fatal outcome despite combined intravitreal and systemic antifungal therapies. We urge clinicians to consider this complication of fusarium infection especially with the widespread use of antifungal prophylaxis that may incur selection of more resistant, invasive fungal species.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are the newest class of anticancer drugs. Pneumonitis is increasingly being recognized as a potential complication of these agents. METHODS We conducted a retrospective study of patients who received ICIs at a comprehensive cancer center. We collected data on demographics, type of malignancy, type of ICI agent, incidence of pneumonitis up to 6 weeks after receiving ICI agent, clinical characteristics, and risk factors for overall survival in patients who develop pneumonitis. RESULTS A total of 654 patients received ICIs during the study period. The most common type of cancer for which ICI was given was adenocarcinoma of the lung (29%), followed by renal cell cancer (12%) and squamous cell lung cancer (12%). Among the study patients, 41% received nivolumab and 32% received pembrolizumab. Other patients in the study received combination of ICIs or ICI plus chemotherapeutic agent, or were part of clinical trial involving ICI. Overall 42 (6.4%) patients developed pneumonitis within 6 weeks after the last dose of treatment of any ICI agent. Of these, 81% of patients had Grade ≥ 2 pneumonitis and 45% of these required hospital admission for pneumonitis, with 10% of them requiring admission to intensive care unit. Overall, patients who received pembrolizumab-containing regimen, had prior chemotherapy, or who never had cancer-related surgery had increased risk of death. CONCLUSION Our large retrospective study shows real-life data of incidence of pneumonitis in patients who are treated with ICIs for cancer treatment. Our data indicate that the incidence of pneumonitis is overall lower than that reported previously with relatively good outcomes.

Abstract
BACKGROUND The efficacy and safety of prophylactic full-dose anticoagulation and antiplatelet therapy in critically ill COVID-19 patients remain uncertain. METHODS COVID-PACT (Prevention of Arteriovenous Thrombotic Events in Critically-ill COVID-19 Patients Trial) was a multicenter, 2×2 factorial, open-label, randomized-controlled trial with blinded end point adjudication in intensive care unit-level patients with COVID-19. Patients were randomly assigned to a strategy of full-dose anticoagulation or standard-dose prophylactic anticoagulation. Absent an indication for antiplatelet therapy, patients were additionally randomly assigned to either clopidogrel or no antiplatelet therapy. The primary efficacy outcome was the hierarchical composite of death attributable to venous or arterial thrombosis, pulmonary embolism, clinically evident deep venous thrombosis, type 1 myocardial infarction, ischemic stroke, systemic embolic event or acute limb ischemia, or clinically silent deep venous thrombosis, through hospital discharge or 28 days. The primary efficacy analyses included an unmatched win ratio and time-to-first event analysis while patients were on treatment. The primary safety outcome was fatal or life-threatening bleeding. The secondary safety outcome was moderate to severe bleeding. Recruitment was stopped early in March 2022 (≈50% planned recruitment) because of waning intensive care unit-level COVID-19 rates. RESULTS At 34 centers in the United States, 390 patients were randomly assigned between anticoagulation strategies and 292 between antiplatelet strategies (382 and 290 in the on-treatment analyses). At randomization, 99% of patients required advanced respiratory therapy, including 15% requiring invasive mechanical ventilation; 40% required invasive ventilation during hospitalization. Comparing anticoagulation strategies, a greater proportion of wins occurred with full-dose anticoagulation (12.3%) versus standard-dose prophylactic anticoagulation (6.4%; win ratio, 1.95 [95% CI, 1.08-3.55]; P=0.028). Results were consistent in time-to-event analysis for the primary efficacy end point (full-dose versus standard-dose incidence 19/191 [9.9%] versus 29/191 [15.2%]; hazard ratio, 0.56 [95% CI, 0.32-0.99]; P=0.046). The primary safety end point occurred in 4 (2.1%) on full dose and in 1 (0.5%) on standard dose (P=0.19); the secondary safety end point occurred in 15 (7.9%) versus 1 (0.5%; P=0.002). There was no difference in all-cause mortality (hazard ratio, 0.91 [95% CI, 0.56-1.48]; P=0.70). There were no differences in the primary efficacy or safety end points with clopidogrel versus no antiplatelet therapy. CONCLUSIONS In critically ill patients with COVID-19, full-dose anticoagulation, but not clopidogrel, reduced thrombotic complications with an increase in bleeding, driven primarily by transfusions in hemodynamically stable patients, and no apparent excess in mortality.

Abstract
BACKGROUND Limited epidemiological data are available on changes in management, benefits, complications, and outcomes after open lung biopsy in patients with ARDS. METHODS We performed a literature search of PubMed, Ovid, and Cochrane databases for articles from the inception of each database till November 2020 that provided outcomes of lung biopsy in ARDS patients. The primary outcome was the proportion of patients that had a change in management with alteration of treatment plan, after lung biopsy. Secondary outcomes included pathological diagnoses and complications related to the lung biopsy. Pooled proportions with a 95% confidence interval (CI) were calculated for the prevalence of outcomes. RESULTS After analysis of 22 articles from 1994 to 2018, a total of 851 ARDS patients (mean age 59.28 ± 7.41, males 56.4%) that were admitted to the ICU who underwent surgical lung biopsy for ARDS were included. Biopsy changed the management in 539 patients (pooled proportion 75%: 95% CI 64-84%). There were 394 deaths (pooled proportion 49%: 95% CI 41-58%). The most common pathologic diagnosis was diffuse alveolar damage that occurred in 30% (95% CI 19-41%), followed by interstitial lung disease in 10% (95% CI 3-19%), and viral infection in 9% (95% CI 4-16%). Complications occurred among 201 patients (pooled proportion 24%, 95% CI 17-31%). The most common type of complication was persistent air-leak among 115 patients (pooled estimate 13%, 95% CI 9-17%). CONCLUSION Despite the high mortality risk associated with ARDS, lung biopsy changed management in about 3/4 of the patients. However, 1/4 of the patients had a complication due to lung biopsy. The risks from the procedure should be carefully weighed before proceeding with lung biopsy.

Abstract
Background Currently there is no consensus on ideal teaching method to train novice trainees in EBUS. Simulation-based procedure training allows direct observation of trainees in a controlled environment without compromising patient safety. Objective We wanted to develop a comprehensive assessment of endobronchial ultrasound (EBUS) performance of pulmonary fellows and assess the impact of a multimodal simulation-based curriculum for EBUS-guided transbronchial needle aspiration. Methods Pretest assessment of 11 novice pulmonary fellows was performed using a three-part assessment tool, measuring EBUS-related knowledge, self-confidence, and procedural skills. Knowledge was assessed by 20 multiple-choice questions. Self-confidence was measured using the previously validated EBUS–Subjective Assessment Tool. Procedural skills assessment was performed on Simbionix BRONCH Express simulator and was modeled on a previously validated EBUS–Skills and Task Assessment Tool (EBUS-STAT), to create a modified EBUS-STAT based on internal faculty input via the Delphi method. After baseline testing, fellows participated in a structured multimodal curriculum, which included simulator training, small-group didactics, and interactive problem-based learning sessions, followed by individual debriefing sessions. Posttest assessment using the same three-part assessment tool was performed after 3 months, and the results were compared to study the impact of the new curriculum. Results The mean knowledge score improved significantly from baseline to posttest (52.7% vs. 67.7%; P = 0.002). The mean EBUS–Subjective Assessment Tool confidence scores (maximum score, 50) improved significantly from baseline to posttest (26 ± 7.6 vs. 35.2 ± 6.3 points; P < 0.001). The mean modified EBUS-STAT (maximum score, 105) improved significantly from baseline to posttest (44.8 ± 10.6 [42.7%] vs. 65.3 ± 11.4 [62.2%]; P < 0.001). There was a positive correlation (r = 0.81) between the experience of the test participants and the modified EBUS-STAT scores. Conclusion This study suggests a multimodal simulation-based curriculum can significantly improve EBUS-guided transbronchial needle aspiration–related knowledge, self-confidence, and procedural skills among novice pulmonary fellows. A validation study is needed to determine if skills attained via a simulator can be replicated in a clinical setting.

Abstract
IMPORTANCE In 2021, the US Preventive Services Task Force (USPSTF) broadened its age and smoking pack-year requirement for lung cancer screening. OBJECTIVES To compare the 2021 USPSTF lung cancer screening criteria with other lung cancer screening criteria and evaluate whether the sensitivity and specificity of these criteria differ by race. DESIGN, SETTING, AND PARTICIPANTS This study included 912 patients with lung cancer and 1457 controls without lung cancer enrolled in an epidemiology study (INHALE [Inflammation, Health, Ancestry, and Lung Epidemiology]) in the Detroit metropolitan area between May 15, 2012, and March 31, 2018. Patients with lung cancer and controls were 21 to 89 years of age; patients with lung cancer who were never smokers and controls who were never smokers were not included in these analyses. Statistical analysis was performed from August 31, 2020, to April 13, 2021. MAIN OUTCOMES AND MEASURES The study assessed whether patients with lung cancer and controls would have qualified for lung cancer screening using the 2013 USPSTF, 2021 USPSTF, and 2012 modification of the model from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCOm2012) screening criteria. Sensitivity was defined as the percentage of patients with lung cancer who qualified for screening, while specificity was defined as the percentage of controls who did not qualify for lung cancer screening. RESULTS Participants included 912 patients with a lung cancer diagnosis (493 women [54%]; mean [SD] age, 63.7 [9.5] years) and 1457 control participants without lung cancer at enrollment (795 women [55%]; mean [SD] age, 60.4 [9.6] years). With the use of 2021 USPSTF criteria, 590 patients with lung cancer (65%) were eligible for screening compared with 619 patients (68%) per the PLCOm2012 criteria and 445 patients (49%) per the 2013 USPSTF criteria. With the use of 2013 USPSTF criteria, significantly more White patients than African American patients with lung cancer (324 of 625 [52%] vs 121 of 287 [42%]) would have been eligible for screening. This racial disparity was absent when using 2021 USPSTF criteria (408 of 625 [65%] White patients vs 182 of 287 [63%] African American patients) and PLCOm2012 criteria (427 of 625 [68%] White patients vs 192 of 287 [67%] African American patients). The 2013 USPSTF criteria excluded 950 control participants (65%), while the PLCOm2012 criteria excluded 843 control participants (58%), and the 2021 USPSTF criteria excluded 709 control participants (49%). The 2013 USPSTF criteria excluded fewer White control participants than African American control participants (514 of 838 [61%] vs 436 of 619 [70%]). This racial disparity is again absent when using 2021 USPSTF criteria (401 of 838 [48%] White patients vs 308 of 619 [50%] African American patients) and PLCOm2012 guidelines (475 of 838 [57%] White patients vs 368 of 619 [60%] African American patients). CONCLUSIONS AND RELEVANCE This study suggests that the USPSTF 2021 guideline changes improve on earlier, fixed screening criteria for lung cancer, broadening eligibility and reducing the racial disparity in access to screening.

Abstract
BACKGROUND Literature regarding trends in incidence and mortality of ST-elevation myocardial infarction (STEMI) in emergency departments (EDs) is limited. OBJECTIVE To study the trends of incidence and mortality of STEMI. METHODS Using the National Emergency Department Sample database in the United States, we identified all ED encounters for patients presenting with STEMI using International Classification of Diseases codes. A linear p-trend was used to assess the trends. RESULTS Out of the 973 million ED encounters represented, 641,762 (65/100,000; mean age 69 [59-81] years, 35.8% female) adult patients were recorded with STEMI. Among the major complications associated with STEMI, a total of 49,401 (7.7%) had cardiac complications, which included acute heart failure (n = 9361, 1.6%), ventricular tachycardia or fibrillation (n = 12,267, 1.91%), conduction block (n = 20,165, 3.1%), and cardiogenic shock (n = 7608, 1.2%). There were 5675 (0.9%) patients recorded with cerebrovascular events, which included acute ischemic stroke among 5205 (0.8%) patients and 470 (0.1%) with transient ischemic attack. Acute kidney injury was recorded for 10,082 (1.6%) patients. The trend for incidence of STEMI in the ED had decreased from 7.76/10,000 in 2011 to 4.07/10,000 in 2018 (linear p-trend 0.0006). However, the yearly mortality of STEMI related to ED encounters had remained relatively steady: 7.56% in 2011 to 7.50% in 2018 (linear p-trend 0.2364). CONCLUSION Despite the fact that the number of patients presenting to the ED with STEMI has been decreasing, the mortality trends have remained steady. Further research of in-hospital STEMI may yield opportunities to reduce the risk of complications, improve patient outcomes and decrease health care burden.

Abstract
Introduction: Although there is evidence describing the immunomodulatory effects of macrolide antibiotics, there is little literature exploring the clinical effects these properties may have and their impact on measurable outcomes. Objective: The purpose of this study was to determine if empiric antimicrobial regimens containing azithromycin shorten time to shock resolution. Methods: A retrospective study was performed in adults with septic shock admitted to intensive care units (ICUs) of 3 university-affiliated, urban teaching hospitals between June 2012 and June 2016. Eligible patients with septic shock required treatment with norepinephrine as the first-line vasopressor for a minimum of 4 hours and received at least 48 hours of antimicrobial treatment from the time of shock onset. Propensity scores were utilized to match patients who received azithromycin to those who did not. Results: A total of 3116 patients met initial inclusion criteria. After propensity score matching, 258 patients were included, with 124 and 134 patients in the azithromycin and control groups, respectively. Median shock duration was similar in patients treated with or without azithromycin (45.6 hr vs 59.7 hr, P = .44). In-hospital mortality was also similar (37.9% vs 38.1%, P = .979). There were no significant differences in mechanical ventilation duration, ICU length of stay (LOS), or hospital LOS. Conclusions: In patients admitted to the ICU with septic shock, empiric azithromycin did not have a significant effect on shock duration, mechanical ventilation duration, ICU LOS, hospital LOS, or in-hospital mortality.

Mortality outcomes associated with invasive aspergillosis among acute exacerbation of chronic obstructive pulmonary disease patient population. Respir Med 2021; 191:106720. [PMID: 34959147 DOI: 10.1016/j.rmed.2021.106720] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 12/14/2021] [Accepted: 12/17/2021] [Indexed: 12/25/2022] [Imported: 08/30/2023]
Abstract
BACKGROUND Literature regarding trends of mortality, and complications of aspergillosis infection among patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is limited. METHODS Data from the National Readmissions Database (NRD) that constitutes 49.1% of the stratified sample of all hospitals in the United States (US), representing more than 95% of the national population were analyzed for hospitalizations with aspergillosis among AECOPD. Predictors and trends related to aspergillosis in AECOPD were evaluated. A Linear p-trend was used to assess the trends. RESULTS Out of the total 7,282,644 index hospitalizations for AECOPD (mean age 69.17 ± 12.04years, 55.3% females), 8209 (11.2/10,000) with primary diagnosis of invasive aspergillosis were recorded in the NRD for 2013-2018. Invasive aspergillosis was strongly associated with mortality (OR 4.47, 95%CI 4.02-4.97, p < 0.001) among AECOPD patients. Malignancy and organ transplant status were predominant predictors of developing aspergillosis among AECOPD patients. The IA-AECOPD group had higher rates of multi-organ manifestations including ACS (3.7% vs 0.44%; p-value0.001), AF (20% vs 18.4%; p-value0.001), PE (4.79% vs1.87%; p-value0.001), AKI (22.3% vs17.5%; p-value0.001), ICU admission (16.5% vs11.9%; p-value0.001), and MV (22.3% vs7.31%; p-value0.001) than the AECOPD group. The absolute yearly trend for mortality of aspergillosis was steady (linear p-trend 0.22) while the yearly rate of IA-AECOPD had decreased from 15/10,000 in 2013 to 9/10,000 in 2018 (linear p-trend 0.02). INTERPRETATION Aspergillosis was related with high mortality among AECOD hospitalizations. There has been a significant improvement in the yearly rates of aspergillosis while the mortality trend was steady among aspergillosis subgroups. Improved risk factor management through goal-directed approach may improve clinical outcomes.

Abstract
OBJECTIVE To study coronary interventions and mortality among patients with ST-elevated myocardial infarction (STEMI) who were admitted with septic shock. METHODS Data from the national emergency department sample (NEDS) that constitutes 20% sample of hospital-owned emergency departments in the United States was analyzed for the septic shock related visits from 2016 to 2018. Septic shock was defined by the ICD codes. RESULTS Out of 1 375 507 adult septic shock patients, 521 300 had a primary diagnosis of septic shock (mean age 67.41±15.67 years, 51.1% females) in the national emergency database for the years 2016 to 2018. Of these patients, 2768 (0.53%) had STEMI recorded during the hospitalization. Mortality rates for STEMI patients were higher than patients without STEMI (52.3% vs 23.5%). Mortality rates improved with PCI among STEMI patients (43.8% vs 56.2%). Coronary angiography was performed among 16% of patients of which percutaneous coronary intervention (PCI) rates were 7.7% among patients with STEMI septic shock. PCI numerically improved mortality, however, had no significant difference than patients without PCI on multivariate logistic regression and univariate logistic regression post coarsened exact matching of baseline characteristics among STEMI patients. Among the predictors, STEMI was a significant predictor of mortality in septic shock patients (OR 2.87, 95% CI 2.37-3.49; P<.001). Age, peripheral vascular disease, were predominant predictors of mortality in STEMI with septic shock subgroup (P <.001). Pneumonia was the predominant underlying infection among STEMI (36.4%) and without STEMI group (29.5%). CONCLUSION STEMI complicating septic shock worsens mortality. PCI and coronary angiography numerically improved mortality, however, had no significant difference from patients without PCI. More research will be needed to improve mortality in such a critically ill subgroup of patients.

Abstract
BACKGROUND Outcomes of cardiac arrest (CA) remain dismal despite therapeutic advances. Literature is limited regarding outcomes of CA in emergency departments (ED). OBJECTIVE To study the possible causes, predictors, and outcomes of CA in ED and in-patient settings throughout the United States (US). METHODS Data from the US national emergency department sample (NEDS) was analyzed for the episodes of CA for 2016-2018. In-hospital CA was divided into in-patient (IPCA) and in the ED (EDCA). Only patients who had cardiopulmonary resuscitation (CPR) within the hospital were included in the study (out-of-hospital were excluded). RESULTS A total of 1,068,847 CA (mean age 63.7 ± 19.4 years, 24%females), of whom 325,062 (30.4%) EDCA and 177,104 (16.6%) IPCA were included in the study. Patients without CPR, 743,785 (69.6%), were excluded. Survival was higher among IPCA 55,821 (31.6%) than the EDCA 32,516 (10%). IPCA encounters had multifactorial associated etiologies including respiratory failure (73%), acidosis (38.7%) sepsis (36.8%) and ST-elevated myocardial infarction (STEMI) (7.3%). Majority of ED arrests (67.1%) had no possible identifiable cause. The predominant known causes include intoxication (7.5%), trauma (6.4%), respiratory failure (5%), and STEMI (2.7%). Cardiovascular interventions had significant survival benefits in IPCA on univariate logistic regression after coarsened exact matching for comorbidities. IPCA had higher intervention rates than EDCA. For all live discharges, a total of 40% of patients were discharged to hospice. CONCLUSION Survival remains dismal among CA patients especially those occurring in the ED. Given that there are considerable variations in the etiology between the two studied cohorts, more research is required to improve the understanding of these factors, which may improve survival outcomes.

Abstract
BACKGROUND Sepsis and cancer continue to be one of the leading causes of death in the United States. Concomitantly, hospitalizations for sepsis with underlying cancer over the years have shown a decrease in mortality. However, large-scale contemporary data on mortality trends in sepsis hospitalizations with underlying malignancy are lacking. RESEARCH QUESTION Are there any identifiable trends in patients hospitalized for sepsis with underlying malignancy versus without malignancy? STUDY DESIGN AND METHODS We performed a retrospective cohort study using the National Inpatient Sample database from 2008 to 2017 to identify sepsis hospitalizations with versus without cancer. Baseline variables and mortality trends were compared between the 2 groups. RESULTS Of the 19,160,734 sepsis hospitalizations identified between 2008 and 2017, 3,913,813 (20.4%) were associated with cancer and 15,246,921 (79.6%) did not have underlying malignancy. Compared with 2008 to 2009, the multivariable-adjusted odds ratio (aOR) of death was lower in 2016 to 2017 for both cancer (aOR: 0.55, 95% confidence interval [CI]: 0.53-0.57) and noncancer-associated (aOR: 0.55, 95% CI: 0.53-0.57) sepsis hospitalizations. The nonsignificant interaction term (P=0.2239) revealed that the rate of decline in mortality did not differ between the 2 groups. Stratification of the mortality in sepsis hospitalizations by various age groups revealed that the odds of death associated with cancer were highest in the younger population (18 to 44 y) with an aOR: 3.40, 95% CI: 3.24-3.57. The aOR: showed a declining trend with increasing age until cancer-associated admissions had slightly lower odds of mortality than the noncancer group at age 85 years old and older (aOR: 0.93, 95% CI: 0.91-0.95). CONCLUSION In the 10-year study period, mortality in cancer and noncancer-associated sepsis hospitalizations has shown a declining trend. Furthermore, differences in mortality between the 2 groups decreased with increasing age.

Abstract
Importance Use of non-invasive respiratory modalities in COVID-19 has the potential to reduce rates of intubation and mortality in severe disease however data regarding the use of high-flow nasal cannula (HFNC) in this population is limited. Objective To interrogate clinical and laboratory features of SARS-CoV-2 infection associated with high-flow failure. Design We conducted a retrospective cohort study to evaluate characteristics of high-flow therapy use early in the pandemic and interrogate factors associated with respiratory therapy failure. Setting Multisite single centre hospital system within the metropolitan Detroit region. Participants Patients from within the Detroit Medical Center (n=104, 89% African American) who received HFNC therapy during a COVID-19 admission between March and May of 2020. Primary outcome HFNC failure is defined as death or intubation while on therapy. Results Therapy failure occurred in 57% of the patient population, factors significantly associated with failure centred around markers of multiorgan failure including hepatic dysfunction/transaminitis (OR=6.1, 95% CI 1.9 to 19.4, p<0.01), kidney injury (OR=7.0, 95% CI 2.7 to 17.8, p<0.01) and coagulation dysfunction (OR=4.5, 95% CI 1.2 to 17.1, p=0.03). Conversely, comorbidities, admission characteristics, early oxygen requirements and evaluation just prior to HFNC therapy initiation were not significantly associated with success or failure of therapy. Conclusions In a population disproportionately affected by COVID-19, we present key indicators of likely HFNC failure and highlight a patient population in which aggressive monitoring and intervention are warranted.

Abstract
Literature regarding trends of incidence, mortality, and complications of acute exacerbation of chronic obstructive pulmonary disease (COPD) in the emergency departments (ED) is limited. What are trends of COPD exacerbation in ED? Data were obtained from the Nationwide Emergency Department Sample (NEDS) that constitutes a 20% sample of hospital-owned EDs and inpatient sample in the US. All ED encounters were included in the analysis. Complications of AECOPD were obtained by using ICD codes. Out of 1.082 billion ED encounters, 5,295,408 (mean age 63.31 ± 12.63 years, females 55%) presented with COPD exacerbation. Among these patients, 353,563(6.7%) had AECOPD-plus (features of pulmonary embolism, acute heart failure and/or pneumonia) while 4,941,845 (93.3%) had exacerbation without associated features or precipitating factors which we grouped as AECOPD. The AECOPD-plus group was associated with statistically significantly higher proportion of cardiovascular complications including AF (5.6% vs 3.5%; p < 0.001), VT/VF (0.14% vs 0.06%; p < 0.001), STEMI (0.22% vs 0.11%; p < 0.001) and NSTEMI (0.65% vs 0.2%; p < 0.001). The in-hospital mortality rates were greater in the AECOPD-plus population (0.7% vs 0.1%; p < 0.001). The incidence of both AECOPD and AECOPD-plus had worsened (p-trend 0.004 and 0.0003) and the trend of mortality had improved (p-trend 0.0055 and 0.003, respectively). The prevalence of smoking for among all COPD patients had increased (p-value 0.004), however, the prevalence trend of smoking among AECOPD groups was static over the years 2010-2018. There was an increasing trend of COPD exacerbation in conjunction with smoking; however, mortality trends improved significantly. Moreover, the rising burden of AECOPD would suggest improvement in diagnostics and policy making regarding management.

Abstract
Literature regarding etiology and trends of incidence of major thoracic vein thrombosis in the United States is limited. To study the causes, complications, in-hospital mortality rate, and trend in the incidence of major thoracic vein thrombosis which could have led to superior vena cava syndrome (SVCS) between 2010 and 2018. Data from the nationwide emergency department sample (NEDS) that constitutes 20% sample of hospital-owned emergency departments (ED) and in-patient sample in the United States were analyzed using diagnostic codes. A linear p-trend was used to assess the trends. Of the total 1082 million ED visits, 37,807 (3.5/100,000) (mean age 53.81 ± 18.07 years, 55% females) patients were recorded with major thoracic vein thrombosis in the ED encounters. Among these patients, 4070 (10.6%) patients had one or more cancers associated with thrombosis. Pacemaker/defibrillator-related thrombosis was recorded in 2820 (7.5%) patients, while intravascular catheter-induced thrombosis was recorded in 1755 (4.55%) patients. Half of the patients had associated complication of pulmonary embolism. A total of 59 (0.15%) patients died during these hospital encounters. The yearly trend for the thrombosis for every 100,000 ED encounters in the United States increased from 2.17/100,000 in 2010 to 5.98/100,000 in 2018 (liner p-trend < 0.001). Yearly trend for catheter/lead associated thrombosis was also up-trending (p-trend 0.015). SVCS is an uncommon medical emergency related to malignancy and indwelling venous devices. The increasing trend in SVCS incidence, predominantly catheter/lead induced, and the high rate of associated pulmonary embolism should prompt physicians to remain vigilant for appropriate evaluation.

Abstract
Literature regarding recent trends and outcomes of acute new-onset heart failure (AHF) with preserved ejection fraction (AHFpEF) and reduced ejection fraction (AHFrEF) is limited. The objective of this study is to study the outcomes of AHFpEF and AHFrEF in the USA. Data from the National Readmissions Database (NRD) sample that constitutes 49.1% of the stratified sample of all hospitals in the USA, representing more than 95% of the national population, were analyzed for hospitalization visits for acute heart failure. ICD-9 and ICD-10 codes were used to identify AHF. A total of 2,559,102 adult index AHF patients (mean age 70.79 ± 14.58 years, 49.4% females), 1,028,970 (40.2%) AHFpEF and 1,330,999 (52%) AHFrEF, were recorded in the National Readmissions Database for the years 2016-2018. A total of 152,465 (5.96%) acute heart failure, 47,271 (4.6%) AHFpEF and 91,973 (6.91%) AHFrEF, died during hospitalization, and 45,810 (1.9%) were readmitted in 30 days among alive discharges. Higher complication rates which included ventricular arrhythmias, acute coronary, and cerebrovascular events were observed among AHFrEF than AHFpEF. Higher proportion of patients with AHFrEF needed intensive care unit and ventilatory support during the hospitalization. The trend of incidence of AHFrEF, mortality among AHFrEF, and overall mortality worsened while AHFpEF improved over the study years 2012-2018 (p-trend < 0.05). Coronary procedures improved mortality rates among AHFpEF and AHFrEF. AHF is very common and is associated with significant mortality. The incidence of AHFrEF and mortality among AHFrEF had worsened, which calls for urgent intervention. Improved recognition of AHF is needed, and guideline-directed treatment of underlying risk factors including coronary artery disease can improve mortality.

Abstract
Hematopoietic stem cell transplantation (HSCT) is used for treatment of a myriad of both malignant and non-malignant disorders. However, despite many advances over the years which have resulted in improved patient mortality, this subset of patients remains at risk for a variety of post-transplant complications. Pulmonary complications of HSCT are categorized into infectious and non-infectious and occur in up to one-third of patients undergoing HSCT. Infectious etiologies include bacterial, viral and fungal infections, each of which can have significant mortality if not identified and treated early in the course of infection. Advances in the diagnosis and management of infectious complications highlight the importance of non-infectious pulmonary complications related to chemoradiation toxicities, immunosuppressive drugs toxicities, and graft-versus-host disease. This report aims to serve as a guide and clinical update of pulmonary complications following HSCT for the general pulmonologist who may be involved in the care of these patients.

Abstract
Sickle cell disease (SCD) is associated with vaso-occlusive episodes that affect different organs. Pulmonary involvement is a major cause of morbidity and mortality in this patient population. We performed a literature search in the PubMed database for articles addressing SCD and pulmonary diseases. Acute chest syndrome is defined as a new radiodensity on chest radiograph imaging with a history consistent of the disease. Management includes broad spectrum antibiotics, pain control, and blood transfusions. Microvasculature infarcts lead to functional asplenia, which in turn increases the risk of being infected with encapsulated organisms. Universal vaccinations and antibiotic prophylaxis play a significant role in decreasing mortality from pulmonary infections. Venous thromboembolism in patients with SCD should be treated in the same manner as in the general population. Pulmonary hypertension in patients with SCD also increases mortality. The American Thoracic Society treatment modalities are based on the underlying etiology which is either directed at treating SCD itself, using vasodilator medications if the patient is in group 1, or using long-term anticoagulation if the patient is group 4 (in terms of etiology). Patients with SCD are more likely to suffer from asthma in comparison to controls. Sleep disorders of breathing should be considered in patients with unexplained nocturnal and daytime hypoxemia, or recurrentvaso-occlusive events. Lastly, the utility of pulmonary function tests still needs to be established.
