Acute Tubulointerstitial Nephritis: A Case Report On Rare Adverse Effect Of Pembrolizumab., Sijan Basnet, Rashmi Dhital, Biswaraj Tharu

Reading Hospital Internal Medicine Residency

Pembrolizumab is a novel immune checkpoint inhibitor approved for use in non-small cell lung carcinoma. There have been a few cases that have associated adverse renal outcomes with pembrolizumab. We present a case of acute kidney injury in a patient on pembrolizumab who was noted to have acute tubulointerstitial nephritis on renal biopsy. Pembrolizumab was discontinued and the patient was started on long-term corticosteroids with a taper. Her renal function improved partially with treatment.

Ambulatory and Primary Care Articles

OBJECTIVES: The aim of this study was to evaluate the safety and effectiveness of percutaneous mechanical thrombectomy using the FlowTriever System (Inari Medical, Irvine, California) in a prospective trial of patients with acute intermediate-risk pulmonary embolism (PE).

BACKGROUND: Catheter-directed thrombolysis has been shown to improve right ventricular (RV) function in patients with PE. However, catheter-directed thrombolysis increases bleeding risk and many patients with PE have relative and absolute contraindications to thrombolysis.

METHODS: Patients with symptomatic, computed tomography-documented PE and RV/left ventricular (LV) ratios ≥0.9 were eligible for enrollment. The primary effectiveness endpoint was core laboratory-assessed change in RV/LV ratio. The …

Health Literacy Screening To Increase Antihypertensive Medication Adherence, Boyann Bonjean

Evidence-Based Practice Project Reports

Hypertension contributes to the risk of developing cardiovascular disease (CVD), stroke, heart attack, and chronic kidney disease (CKD) (Abegaz et al., 2016; Weir, 2014; Whelton et al., 2017). Evidence indicates that 30 to 50% of people who are prescribed antihypertensive medication therapy are nonadherent (Hedna et al., 2015). Non-adherence to antihypertensive medications is a major contributor to hypertension treatment failure (Al Ghurair et al., 2012; Hu, 2016; Whelton et al., 2017). Evidence has shown that low health literacy may impact antihypertensive therapy (Slade, 2017). The purpose of this EBP project was to provide an organizational change by implementing a health …

The In Vivo Effects Of Alcohol In Lung And Liver Are At Least Partially Mediated Through The Alpha 4 Nicotinic Acetylcholine Receptor, J. Ritzenthaler, E. Torres-Gonzalez, G. E. Arteel, J. Roman

Division of Pulmonary, Allergy, and Critical Care Medicine Posters

Rational: Chronic alcohol abuse is a major risk factor for the development of acute lung injury, with 40% of annual cases in the U.S. linked to this disorder. Alcohol is not only associated with increased incidence of acute lung injury in at-risk individuals, but also increased mortality. The exact mechanisms by which alcohol abuse renders the host susceptible to acute lung injury remain poorly defined. We have reported that α4 nicotinic acetylcholine receptors (α4 nAChRs) may serve as potential sensors for alcohol in lung fibroblasts; however, we have not tested their role in vivo.

Methods: To test the role of …

Dehydrated Hereditary Stomatocytosis Causing Sever Ascites Leading To Pulmonary Hypoplasia And Respiratory Insufficiency In A Neonate, Michael D. Mcdowell Jr, Christopher M. Oermann

Posters

Care Presentation: EM is a 32.5-week EGA infant who was born with sever congenital ascites (following repeated prenatal paracentesis) identified on prenatal ultrasound. Initial chest-abdomen imaging is shown in Figure 1. He required CPAP at delivery but was weaned of high flow nasal cannula with intermittent episodes of prolonged intubation during repeat paracentesis. Paracentesis demonstrated simple ascites rather than chylous fluid. Lymphangiograms demonstrated transient lymphatic leakage with resolution. Genetic evaluation revealed a pathogenic mutation in the PIEZO 1 gene for autosomal dominant DHS. This disorder had reduced penetrance and variable expressivity and symptoms range for absence of clinical features to …

Neurocardiac Risk Stratification 6 Hours After Resuscitation From Cardiac Arrest, A Bilkanovic, Z Haxhija, L Lucas, J Dziodzio, R R. Riker, T May, H Friberg, D B. Seder

MaineHealth Maine Medical Center

Introduction:

• An increasing number of patients are resuscitated from out-ofhospital cardiac arrest. Triage to optimal treatment pathways could improve and increase the efficacy of post-resuscition care.

• Despite great variability in etiology, duration, and patterns of injury from cardiac arrest, post-resuscitation treatment guidelines emphasize standard treatments. We hypothesize that by categorizing competing risks very early after resuscitation, it may be possible to improve the efficacy and efficiency of care.

• When measured very early after resuscitation, suppression ratio (SR, the percentage of suppressed EEG), correlates with severity of brain injury and the likelihood of poor neurological outcome.

• The …

Recent Progress In The Theranostics Application Of Nanomedicine In Lung Cancer., Anubhab Mukherjee, Manash Paul, Sudip Mukherjee

Articles, Abstracts, and Reports

Lung cancer is one of the leading causes of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) causes around 80% to 90% of deaths. The lack of an early diagnosis and inefficiency in conventional therapies causes poor prognosis and overall survival of lung cancer patients. Recent progress in nanomedicine has encouraged the development of an alternative theranostics strategy using nanotechnology. The interesting physico-chemical properties in the nanoscale have generated immense advantages for nanoparticulate systems for the early detection and active delivery of drugs for a better theranostics strategy for lung cancer. This present review provides a detailed overview of the …

Introduction. Tuberculosis, a major cause of morbidity and mortality, is the second cause of death from an infectious disease, after HIV/AIDS. Each second, a new infection occurs around the globe. Pulmonary tuberculosis can equally affect a performance athlete as well as an aspiring athlete. Physical exercise must be individualized and customized. Pulmonary rehabilitation guides 3 recommend types of exercises for patients with obstructive pathology: stretching, cardiovascular exercise or aerobics. Exercises must be started under medical supervision and must be interrupted if: the ventricular altitude increases above the maximum estimated level for the age, oxygen saturation (SaO2). Aim. The current review …

The Effects Of Implementing A Smartphone Application To Improve Asthma Self-Management In Adults, Lindsay J. Humpfer

Evidence-Based Practice Project Reports

Asthma is one of the most common chronic diseases, affecting 20.4 million adults in the United States (CDC, 2018). While asthma can generally be controlled, patients having an exacerbation may experience missed days of work and school, limitations in daily activities, decreased enjoyment of life, and decreased productivity at home, work, and school (MarcanoBelisario et al., 2013). Therefore, the purpose of this project was to improve patients’ overall asthma control and asthma-related quality of life by encouraging self-management through patient education and the implementation of a mobile smartphone application. A total of 26 adult primary care patients with asthma participated …

Direct Lung Sampling Indicates That Established Pathogens Dominate Early Infections In Children With Cystic Fibrosis., Peter Jorth, Zarmina Ehsan Md, Amir Rezayat, Ellen Caldwell, Christopher Pope, John J. Brewington, Christopher H. Goss, Dan Benscoter, John P. Clancy, Pradeep K. Singh

Manuscripts, Articles, Book Chapters and Other Papers

Culture and sequencing have produced divergent hypotheses about cystic fibrosis (CF) lung infections. Culturing suggests that CF lungs are uninfected before colonization by a limited group of CF pathogens. Sequencing suggests diverse communities of mostly oral bacteria inhabit lungs early on and diversity decreases as disease progresses. We studied the lung microbiota of CF children using bronchoscopy and sequencing, with measures to reduce contamination. We found no evidence for oral bacterial communities in lung lavages that lacked CF pathogens. Lavage microbial diversity varied widely, but decreases in diversity appeared to be driven by increased CF pathogen abundance, which reduced the …

Bhattacharya, Gregory S. Troutman, Frances Mao, Arieh L. Fox, Monique S. Tanna, Payman Zamani, E. Wilson Grandin, Jonathan N. Menachem, Edo Y. Birati, Julio A. Chirinos, Sula Mazimba, Kerri Akaya Smith, Steven M. Kawut, Paul R. Forfia, Anjali Vaidya, Jeremy A. Mazurek

Student Papers, Posters & Projects

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 …

Multidisciplinary Care For Adult Hermansky-Pudlak Syndrome Patients In Puerto Rico, Isabel Becerra, Shirley Martinez, Atencio Xavier, Torrens Jonathan, Juan Alemany, Eric Cruz, Felix Rivera Borges, Monica Egozcue, Jesse Roman, Rosa Roman

Division of Pulmonary, Allergy, and Critical Care Medicine Posters

Background: Hermansky-Pudlak syndrome (HPS) is an autosomal recessive rare disease characterized by oculo-cutaneous albinism, bleeding diathesis due to platelet dysfunction, and is sometimes accompanied by immunodeficiency, granulomatous colitis, and/or interstitial lung disease / pulmonary fibrosis. Puerto Rico houses the highest concentration of patients with HPS, especially HPS-1, which is considered quite severe and often associated with pulmonary fibrosis. We believe that the establishment of an HPS Multidisciplinary Clinic in Puerto Rico would improve outcomes.

Methods: A multidisciplinary clinic was started in November 2018 and another was held in February 2019 at the Mayaguez Medical Center located in the Southwest region …

Articles, Abstracts, and Reports

The development of cancer is driven by the accumulation of many oncogenesis-related genetic alterations and tumorigenesis is triggered by complex networks of involved genes rather than independent actions. To explore the epistasis existing among oncogenesis-related genes in lung cancer development, we conducted pairwise genetic interaction analyses among 35,031 SNPs from 2027 oncogenesis-related genes. The genotypes from three independent genome-wide association studies including a total of 24,037 lung cancer patients and 20,401 healthy controls with Caucasian ancestry were analyzed in the study. Using a two-stage study design including discovery and replication studies, and stringent Bonferroni correction for multiple statistical analysis, we …

Primary Pulmonary Plasmacytoma Presenting With Rare Igg Lambda Monoclonal Gammopathy, Yasmin Rahim, Farrukh Zia Tareen, Rashida Ahmed, Javaid Khan

Section of Pulmonary & Critical Care

Extramedullaryplasmacytoma (EMP) represents a peculiar and typically progressive malignancy that can originate outside the bone marrow. Primary pulmonary plasmacytoma (PPP) is a rare subset of EMP, confined to the lung. A 55-year-old man, diabetic, non-smoker presented to our clinic with a right chest wall swelling. A routine chest radiograph showed a well-circumscribed opacity in the right upper lung zone. A CT of the chest revealed a large right upper lobe mass with extensive local infiltration. Biopsy and immunohistochemical evaluation led to a diagnosis of PPP. Screening for multiple myeloma was negative. Serum immunofixation showed an IgG lambda monoclonal gammopathy, found …

Rethinking Intravenous Catheter Size And Location For Computed Tomography Pulmonary Angiography, Travis Marshall, Nae Meng Chen, Eric Nguyen, David E. Slattery, Tony Zitek

School of Medicine Faculty Research

Introduction: Computed tomography pulmonary angiography (CTPA) is the test of choice for diagnosis of pulmonary embolism (PE) in the emergency department (ED), but this test may be indeterminate for technical reasons such as inadequate contrast filling of the pulmonary arteries. Many hospitals have requirements for intravenous (IV) catheter size or location for CTPAs to reduce the chances of inadequate filling, but there is a lack of clinical data to support these requirements. The objective of this study was to determine if a certain size or location of IV catheter used for contrast for CTPA is associated with an increased chance …

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 …

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 …
