Resident Endothelial Cells And Endothelial Progenitor Cells Restore Endothelial Barrier Function After Inflammatory Lung Injury, S. Z. Mao, X. B. Ye, G. Liu, D. M. Song, S. F. Liu

Journal Articles

Objective Disruption of endothelial barrier integrity is a characteristic of many inflammatory conditions. However, the origin and function of endothelial cells (ECs) restoring endothelial barrier function remain unknown. This study defined the roles of resident ECs (RECs) and bone marrow-derived endothelial progenitor cells (BMDEPCs) in endothelial barrier restoration after endotoxemic lung injury. Approach and Results We generated mice that enable to quantify proliferating RECs or BMDEPCs and also to study the causal link between REC or BMDEPC proliferation and endothelial barrier restoration. Using these mouse models, we showed that endothelial barrier restoration was associated with increased REC and BMDEPC proliferation. …


Respiratory Failure With Hilar Mass: Role Of Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration In The Medical Intensive Care Unit, A. Chichra, K. W. Lama, S. J. Koenig Jan 2015

Respiratory Failure With Hilar Mass: Role Of Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration In The Medical Intensive Care Unit, A. Chichra, K. W. Lama, S. J. Koenig

Journal Articles

We report the case of a 58-year-old man on chronic steroid therapy, who developed a rapidly progressive right upper lobe infiltrate/mass that extended into the right hilum. Respiratory failure necessitated endotracheal intubation. Broad spectrum antibiotics were initiated without clinical improvement and because of his immunosuppressive therapy opportunistic pathogens were considered. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was performed in the Medical Intensive Care Unit (MICU) with rapid onsite evaluation. Specimens obtained from the right hilar mass revealed organisms suspicious for cryptococcal infection, subsequently confirmed via a culture. No complications occurred during the EBUS procedure despite the patient requiring vasopressor support …


"Saw-Tooth Sign" In Upper Airway Disorders - A Case Report, S. Sahni, A. Blood, S. Paulus, A. Talwar Jan 2015

"Saw-Tooth Sign" In Upper Airway Disorders - A Case Report, S. Sahni, A. Blood, S. Paulus, A. Talwar

Journal Articles

Spirometry flow-volume loop measurement is the screening test of choice to rule out obstructive lung diseases. Flow oscillations occasionally seen on flow volume loops, referred to as a "saw-tooth" sign, are thought to be due to an upper airway obstructive processes associated with upper airway collapsibility. Widely described in obstructive sleep apnea syndrome, flow oscillations have also been linked to many other upper airway pathologies. The mechanism by which flow oscillations occur is centered on the inspiratory and expiratory flow of air. It has been theorized that the mechanism of flow oscillations result from rapid intermittent changes in driving pressure …


Ultrasound In The Diagnosis And Management Of Pleural Effusions, N. J. Soni, R. Franco, M. I. Velez, D. Schnobrich, R. Dancel, M. I. Restrepo, P. H. Mayo Jan 2015

Ultrasound In The Diagnosis And Management Of Pleural Effusions, N. J. Soni, R. Franco, M. I. Velez, D. Schnobrich, R. Dancel, M. I. Restrepo, P. H. Mayo

Journal Articles

We review the literature on the use of point-of-care ultrasound to evaluate and manage pleural effusions. Point-of-care ultrasound is more sensitive than physical exam and chest radiography to detect pleural effusions, and avoids many negative aspects of computerized tomography. Additionally, point-of-care ultrasound can assess pleural fluid volume and character, revealing possible underlying pathologies and guiding management. Thoracentesis performed with ultrasound guidance has lower risk of pneumothorax and bleeding complications. Future research should focus on the clinical effectiveness of point-of-care ultrasound in the routine management of pleural effusions and how new technologies may expand its clinical utility.

Lps Down-Regulates Specificity Protein 1 Activity By Activating Nf-Kappab Pathway In Endotoxemic Mice, X. Ye, H. Liu, Y. S. Gong, S. F. Liu Jan 2015

Lps Down-Regulates Specificity Protein 1 Activity By Activating Nf-Kappab Pathway In Endotoxemic Mice, X. Ye, H. Liu, Y. S. Gong, S. F. Liu

Journal Articles

BACKGROUND: Specificity protein (Sp) 1 mediates the transcription of a large number of constitutive genes encoding physiological mediators. NF-kappaB mediates the expression of hundreds of inducible genes encoding pathological mediators. Crosstalk between Sp1 and NF-kappaB pathways could be pathophysiologically significant, but has not been studied. This study examined the crosstalk between the two pathways and defined the role of NF-kappaB signaling in LPS-induced down-regulation of Sp1 activity. METHODS AND MAIN FINDINGS: Challenge of wild type mice with samonelia enteritidis LPS (10 mg/kg, i.p.) down-regulated Sp1 binding activity in lungs in a time-dependent manner, which was concomitantly associated with an increased …


Non-Small-Cell Lung Cancer Clinicopathologic Features And Survival Outcomes In Asian Pacific Islanders Residing In The United States: A Seer Analysis, M. S. Hamid, R. Shameem, K. Gafoor, J. George, B. Mina, K. Sullivan Jan 2015

Non-Small-Cell Lung Cancer Clinicopathologic Features And Survival Outcomes In Asian Pacific Islanders Residing In The United States: A Seer Analysis, M. S. Hamid, R. Shameem, K. Gafoor, J. George, B. Mina, K. Sullivan

Journal Articles

Background. The objective of our study was to ascertain racial/ethnic disparities in Asian/Pacific Islanders (API) for non-small-cell lung cancer (NSCLC) clinicopathologic features and survival outcomes based on various tumor characteristics and treatment modalities. Method. SEER database identified invasive NSCLC cases from 2004 to 2010. Variables included American Joint Committee on Cancer (AJCC) stage 7, tumor grade, tumor size, histology, age, marital status, radiation, surgery, and reason for no surgery. The Kruskall-Wallis test and the Z test were used to examine differences between races/ethnicities and the referent, non-Hispanic white (NHW). Multivariate Cox proportional analyses were used to establish the weight of …

Pulmonary Rehabilitation And Exercise In Pulmonary Arterial Hypertension: An Underutilized Intervention, S. Sahni, B. Capozzi, A. Iftikhar, V. Sgouras, M. Ojrzanowski, A. Talwar Jan 2015

Pulmonary Rehabilitation And Exercise In Pulmonary Arterial Hypertension: An Underutilized Intervention, S. Sahni, B. Capozzi, A. Iftikhar, V. Sgouras, M. Ojrzanowski, A. Talwar

Journal Articles

Pulmonary arterial hypertension (PAH) is a rare and devastating disease characterized by progressive increases in pulmonary arterial pressure and pulmonary vascular resistance which eventually leads to right ventricular failure and death. Early thought process was that exercise and increased physical activity may be detrimental to PAH patients however many small cohort trials have proven otherwise. In addition to the many pharmaceutical options, exercise and pulmonary rehabilitation have also been shown to increase exercise capacity as well as various aspects of psychosomatic health. As pulmonary and exercise rehabilitation become more widely used as an adjuvant therapy patient outcomes improve and physicians …

Case Report: Pulmonary Kaposi Sarcoma In A Non-Hiv Patient, A. Kodra, M. Walczyszyn, C. Grossman, D. Zapata, T. Rambhatla, B. Mina

Journal Articles

Kaposi Sarcoma (KS) is an angioproliferative tumor associated with human herpes virus 8 (HHV-8). Often known as one of the acquired immunodeficiency syndrome (AIDS)-defining skin diseases, pulmonary involvement in KS has only been discussed in a handful of case reports, rarely in a non-HIV patient. Herein we report the case of a 77 year-old- male who presented with a 6-week history of progressive dyspnea on exertion accompanied by productive cough of yellow sputum and intermittent hemoptysis. His past medical history was significant for Non-Hodgkin's Follicular B-Cell Lymphoma (NHL). Patient also had biopsy-confirmed cutaneous KS. His physical exam was notable for …
