BACKGROUND: Point-of-care (POC) hemoglobin testing has the potential to revolutionize massive transfusion strategies. No prior studies have compared POC and central laboratory testing of hemoglobin in patients undergoing massive transfusions.

METHODS: We retrospectively compared the results of our point-of-care hemoglobin test (EPOC®) to our core laboratory complete blood count (CBC) hemoglobin test (Sysmex XE-5000™) in patients undergoing massive transfusion protocols (MTP) for hemorrhage. One hundred seventy paired samples from 90 patients for whom MTP was activated were collected at a single, tertiary care hospital between 10/2011 and 10/2017. Patients had both an EPOC® and CBC hemoglobin performed within 30 min …

Statins are some of the most widely used drugs worldwide, but one of their major side effects is myotoxicity. Using mouse myoblast (C2C12) and human alveolar rhabdomyosarcoma cell lines (RH30) in both 2-dimensional (2D) and 3-dimensional (3D) cell culture, we investigated the mechanisms of simvastatin's myotoxicity. We found that simvastatin significantly reduced cell viability in C2C12 cells compared to RH30 cells. However, simvastatin induced greater apoptosis in RH30 compared to C2C12 cells. Simvastatin-induced cell death is dependent on geranylgeranyl pyrophosphate (GGPP) in C2C12 cells, while in RH30 cells it is dependent on both farnesyl pyrophosphate (FPP) and GGPP. Simvastatin inhibited …

The Case For Patient Navigation In Lung Cancer Screening In Vulnerable Populations: A Systematic Review., Christine S Shusted, Julie A Barta, Michael Lake, Rickie Brawer, Brooke Ruane, Teresa E Giamboy, Baskaran Sundaram, Nathaniel R Evans, Ronald E Myers, Gregory C Kane

Division of Pulmonary and Critical Care Medicine Faculty Papers

Patient navigation has been proposed to combat cancer disparities in vulnerable populations. Vulnerable populations often have poorer cancer outcomes and lower levels of screening, adherence, and treatment. Navigation has been studied in various cancers, but few studies have assessed navigation in lung cancer. Additionally, there is a lack of consistency in metrics to assess the quality of navigation programs. The authors conducted a systematic review of published cancer screening studies to identify quality metrics used in navigation programs, as well as to recommend standardized metrics to define excellence in lung cancer navigation. The authors included 26 studies evaluating navigation metrics …

Bitter Taste Receptors For Asthma Therapeutics., Ajay P. Nayak, Sushrut D. Shah, James V. Michael, Deepak A. Deshpande

Center for Translational Medicine Faculty Papers

Clinical management of asthma and chronic obstructive pulmonary disease (COPD) has primarily relied on the use of beta 2 adrenergic receptor agonists (bronchodilators) and corticosteroids, and more recently, monoclonal antibody therapies (biologics) targeting specific cytokines and their functions. Although these approaches provide relief from exacerbations, questions remain on their long-term efficacy and safety. Furthermore, current therapeutics do not address progressive airway remodeling (AR), a key pathological feature of severe obstructive lung disease. Strikingly, agonists of the bitter taste receptors (TAS2Rs) deliver robust bronchodilation, curtail allergen-induced inflammatory responses in the airways and regulate airway smooth muscle (ASM) cell proliferation and mitigate …

Patient Registries In Idiopathic Pulmonary Fibrosis., Daniel A. Culver, Jürgen Behr, John A. Belperio, Tamera J. Corte, Joao A. De Andrade, Kevin R. Flaherty, Mridu Gulati, Tristan J. Huie, Lisa H. Lancaster, Jesse Roman, Christopher J. Ryerson, Hyun J. Kim

Over the past decade, several large registries of patients with idiopathic pulmonary fibrosis (IPF) have been established. These registries are collecting a wealth of longitudinal data on thousands of patients with this rare disease. The data collected in these registries will be complementary to data collected in clinical trials because the patient populations studied in registries have a broader spectrum of disease severity and comorbidities and can be followed for a longer period of time. Maintaining the quality and completeness of registry databases presents administrative and resourcing challenges, but it is important to ensuring the robustness of the analyses. Data …

Right Ventricular Outflow Tract Velocity Time Integral-To-Pulmonary Artery Systolic Pressure Ratio: A Non-Invasive Metric Of Pulmonary Arterial Compliance Differs Across The Spectrum Of Pulmonary Hypertension., Priyanka T.

Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH) and is predictive of outcomes. We assessed whether the echocardiographically derived ratio of RV outflow tract velocity time integral to PA systolic pressure (RVOT-VTI/PASP) (a) correlates with invasive PAC, (b) discriminates heart failure with preserved ejection-associated PH (HFpEF-PH) from pulmonary arterial hypertension (PAH), and (c) is associated with functional capacity. We performed a retrospective cohort study of patients with PAH (n = 70) and …

Sociodemographic Background Characteristics Of Patients Who Participate In A Lung Cancer Screening Program, Amber Zhang, Marcella Pimpinelli, Brooke Ruane, Russell K. Mcintire, Julie Barta, Md, Hee-Soon Juon, Bridget Jackson

Phase 1

Introduction: Despite decreasing lung cancer incidence and mortality rates, disparities in prevalence and outcomes persist between Black and White patients. Secondary analysis of the National Lung Screening Trial found screening with low-dose CT (LDCT) reduced lung cancer mortality more in Blacks than Whites. However, it is unknown if racial disparities exist in screening results, and the involved sociodemographic factors.

Objective: The study aims to analyze characteristics that may predict screening outcomes (Lung-RADS category) in patients who received LDCT through the Jefferson Lung Cancer Screening Program (LCSP).

Methods: Retrospective data (n=733, May 2015 to July 2017) were merged with prospective …

Bova Is Superior To Spesi In Identification Of High Risk Pulmonary Embolism Patients, J. Dibello, P. Khaing, E. Gupta, C. Au, T. Chengsupanimit, B. K. Awsare, M. Baram, F. M. West, G. C. Kane

Phase 1

Introduction: Prognostic models exist for the purpose of stratifying patients with acute pulmonary embolism. Of these, the Pulmonary Embolism Severity Index (PESI) and the simplified PESI (sPESI) are the most well-known, although more recent composite models, like the BOVA score, are now being studied and implemented. Comparative efficacy of these scores to predict long term mortality is not well established.

Methods: We performed a retrospective analysis of all consecutive patients diagnosed with PE using computed tomography scan from 2014-2016 at an urban tertiary-referral medical center. Cox proportional hazard analyses were performed to compare the performance of two prognostic …

Global Epidemiology Of Lung Cancer., Julie A. Barta, Md, Charles A. Powell, Juan P. Wisnivesky

Division of Pulmonary and Critical Care Medicine Faculty Papers

While lung cancer has been the leading cause of cancer-related deaths for many years in the United States, incidence and mortality statistics - among other measures - vary widely worldwide. The aim of this study was to review the evidence on lung cancer epidemiology, including data of international scope with comparisons of economically, socially, and biologically different patient groups. In industrialized nations, evolving social and cultural smoking patterns have led to rising or plateauing rates of lung cancer in women, lagging the long-declining smoking and cancer incidence rates in men. In contrast, emerging economies vary widely in smoking practices and …
