Shortened telomere lengths (TLs) can be caused by single nucleotide polymorphisms and loss-of-function mutations in telomere-related genes (TRG), as well as ageing and lifestyle factors such as smoking. Our objective was to determine if shortened TL is associated with interstitial lung disease (ILD) in individuals with rheumatoid arthritis (RA). This is the largest study to demonstrate and replicate that shortened peripheral blood leukocytes-TL is associated with ILD in patients with RA compared with RA without ILD in a multinational cohort, and short PBL-TL was associated with baseline disease severity in RA-ILD as measured by forced vital capacity percent predicted.

Standardizing The Discharge Process To Reduce Copd Readmission Rates, Kristine Doligosa

Doctor of Nursing Practice Scholarly Projects

Background: Frequent acute exacerbations of chronic obstructive pulmonary disease (AECOPD) can lead to unfavorable patient outcomes and costly readmissions. Inadequate patient support during discharge and an inconsistent discharge process are factors contributing to high readmissions in this population.

Purpose: This quality improvement project aimed to reduce COPD-related hospital readmissions by standardizing the discharge process for patients admitted with AECOPD and identify patient risk factors for readmission.

Methods: Following a quantitative and quasi-experimental design, this project standardized the discharge process for patients admitted with AECOPD using the Re-Engineered Discharge Toolkit components and a discharge care bundle. The project was …

Kvx-053, A Protein Tyrosine Phosphatase 4a3 Inhibitor, Ameliorates Sars-Cov-2 Spike Protein Subunit 1 - Induced Acute Lung Injury In Mice, Pavel A. Solopov, Ruben Manuel Luciano Colunga Biancatelli, Tierney Day, Betsy Gregory, Elizabeth R. Sharlow, John S. Lazo, John D. Catravas

Bioelectrics Publications

The Acute Respiratory Distress Syndrome (ARDS), often preceded by acute lung injury (ALI), is characterized by the accumulation of inflammatory fluid in the lung alveoli, leaky alveolar epithelium and endothelium, and overexpression of pro-inflammatory cytokines. This progression from ALI to ARDS is a major contributor to the high mortality observed in COVID-19 patients. The Spike protein of SARS-CoV-2 binds to lung ACE2 and, in addition to facilitating viral cell entry, it plays an important role in the development of ALI and ARDS, especially in the later phases of COVID-19 as well as long COVID. Protein tyrosine phosphatase (PTP) 4A3 is …

Titratable, Weight-Based Cisatracurium Infusions For Ventilation Synchrony In Ards, Nanako Miimi, Pharmd, Celine Munoz

Books, Presentations, Posters, Etc.

Abstract: Cisatracurium is a non-depolarizing neuromuscular blocking agent used for paralysis in paitents with acute respiratory distress syndrome on mechanical ventilation. Paralysis prevents ventilator dyssynchrony and reduces patient’s work of breathing, which decreases the risk of pneumothorax. On November 1, 2023, PSVMC critical care units transitioned from fixed dosing of cisatracurium for ARDS to a weight-based, titratable dosing protocol. A single-center retrospective cohort study demonstrated cisatracurium titrated using train-of-four was associated with similar ventilatory and clinical outcomes with three folds reduction in cisatracrurium dose in comparison to fixed dose strategy. The purpose of this project is to evaluate the drug …

A Novel Non-Rodent Animal Model Of Hydrochloric Acid-Induced Acute And Chronic Lung Injury, Pavel A. Solopov, Ruben Manuel Luciano Biancatelli, Tierney Day, Christiana Dimitropoulou, John D. Catravas

Bioelectrics Publications

Hydrochloric acid is one of the most prevalent and hazardous chemicals. Accidental spills occur in industrial plants or during transportation. Exposure to HCl can induce severe health impairment, including acute and chronic pulmonary diseases. We have previously described the molecular, structural, and functional aspects of the development of chronic lung injury and pulmonary fibrosis caused by intratracheal instillation of HCl in mice. Although mouse models of human disease have many advantages, rodents are evolutionary far from human and exhibit significant anatomical and physiological differences. Genetic and anatomic similarities between rabbits and humans are significantly higher. Rabbit models of HCl-induced lung …

Prioritizing Clinically Significant Lung Cancer Somatic Mutations For Targeted Therapy Through Efficient Ngs Data Filtering System, Jinlian Wang, Hui Li, Hongfang Liu

Faculty, Staff and Student Publications

In the realm of lung cancer treatment, where genetic heterogeneity presents formidable challenges, precision oncology demands an exacting approach to identify and hierarchically sort clinically significant somatic mutations. Current Next-Generation Sequencing (NGS) data filtering pipelines, while utilizing various external databases for mutation screening, often fall short in comprehensive integration and flexibility needed to keep pace with the evolving landscape of clinical data. Our study introduces a sophisticated NGS data filtering system, which not only aggregates but effectively synergizes diverse data sources, encompassing genetic variants, gene functions, clinical evidence, and an extensive body of literature. This system is distinguished by a …

Common variable immunodeficiency (CVID) can be complicated by granulomatous disease, often granulomatous lymphocytic interstitial lung disease (GLILD). Granulomatous interstitial nephritis represents an atypical presentation in pediatrics. Our patient is a previously healthy 13-year-old white male with a recent diagnosis of CVID. He presented with a rash and laboratory findings included pancytopenia (white blood cells 2.6 cells × 103/μl, hemoglobin 11.8 g/dl, platelets 60 × 103/μl), hypercalcemia (14.9 mg/dl), elevated Vit D 1,25 OH level (>200 pg/ml), hyperuricemia (8.8 mg/dl), and acute kidney injury (AKI) (serum creatinine 1.1 mg/dl; baseline 0.64 mg/dl). A broad infectious workup was unremarkable. The rash …

Airway complications following lung transplantation remain an important cause of morbidity and mortality. We aimed to identify the incidence, risk factors and outcomes associated with clinically significant airway ischemia (CSAI) in our center. We reviewed 217 lung transplants (386 airway anastomoses) performed at our institution between February 2016 and December 2020. Airway images were graded using the 2018 ISHLT grading guidelines modified slightly for retrospective analysis. Airways were considered to have CSAI if they developed ischemia severity >B2, stenosis >50%, and/or any degree of dehiscence within 6-months of transplant. Regression analyses were used to evaluate outcomes and risk factors for …
