Articles

Cupressaceae pollen is one of the major airborne allergens of the Mediterranean region and in other regions around the world. Pollen production of these species causes considerable allergic problems during winter, being this type of pollen the most abundant in this period of the year. This work aims to relate phenology, meteorology and airborne pollen records in these species. Aerobiological sampling was carried out in Badajoz (SW Spain) from 2016 to 2018 using Hirst-type volumetric sampler. Pollination phenology was studied in 50 specimens, ten of Cupressus macrocarpa, ten of Cupressus arizonica, 15 of Cupressus sempervirens and 15 of …

There are many challenges in developing an effective HIV vaccine, including the lack of knowledge regarding the immune response to the virus and its diverse nature. Ethical concerns further complicate research. A recent phase III trial was performed in Thailand and showed that a significant reduction in HIV infection is possible. Pharmacists need to stay informed of these important breakthroughs in AIDS research in order to provide quality health information to patients in their community. This paper aims to evaluate the …

How To Use Peanut Ige Levels To Predict Challenge Outcomes In The Pediatric Population, Nalin U.G., Jay Portnoy, Jodi Shroba, Salman Aljubran

Posters

Introduction: The accepted clinical practice is to consider oral challenge when peanut IgE levels are 2.0 kUA/L or less in patients with a history of a major reaction or less than 5.0 kUA/L in patients with only sensitization. Certain populations are predisposed to having increased IgE levels, and these patients are often not offered challenges due to elevated numbers.

Methods: We reviewed unidentified patients information from January 2017 to July 2019 on peanut IgE levels and oral challenge outcomes through REDCap database. A ROC using SPSS from IBM was used and the points from the ROC curve were used to …

Tilapia Consumption And Scombroid Poisoning., Ehizogie Edigin, Prasanth Lingamaneni, Juan Sarmiento, Hafeez Shaka, Sanjay A Patel

Ambulatory and Primary Care Articles

Scombroid poisoning, also known as histamine fish poisoning, typically occurs after eating dark meat fish. Higher levels of histidine, which is converted to histamine, causes anaphylaxis-like symptoms upon ingestion. There are few reported cases of scombroid in humans secondary to light meat fish. We present a case secondary to tilapia consumption.

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 …

Social Aspects Of Food-Sensitive Adults, Jean Elizabeth Duane

Electronic Theses and Dissertations

People living with food-related illnesses find themselves subjugated by commonly held ideologies causing awkwardness in social situations. The current study is a qualitative analysis addressing how people with celiac disease (CD) navigate social situations in light of dominant beliefs that influence behaviors. Initially, I identify macro-level patriarchal, religious, sexist, ableist and etiquette-related commensality ideologies that disadvantage those with CD. Drawing from the communication narrative sense making (CNSM) theory that supports storytelling and memorable messages as a sense-making tool for individuals diagnosed with chronic illness and their family members, this work highlights retrospective stories and memorable messages from 20 randomly selected …

Urban Aerobiological Risk Mapping Of Ornamental Trees Using A New Index Based On Lidar And Kriging: A Case Study Of Plane Trees, Raúl Pecero-Casimiro, Santiago Fernández-Rodríguez, Rafael Tormo-Molina, Alejandro Monroy-Colín, Inmaculada Silva-Palacios, Juan Pedro Cortés-Pérez, Ángela Gonzalo-Garijo, J. M. Maya-Manzano

Articles

Ornamental trees bring benefits for human health, including reducing urban pollution. However, some species, such as plane trees (Platanus sp.), produce allergenic pollen. Consequently, urban maps are a valuable tool for allergic patients and allergists, but they often fail to include variables that contribute to the “building downwash effect”, such as the width and shape of streets and the height of buildings. Other factors that directly influence pollen dispersion (slopes and other geographical features) also have not traditionally been discussed. The LiDAR (Laser Imaging Detection and Ranging) technique enables one to consider these variables with high accuracy. This work proposes …

Journal Articles: Pulmonary & Critical Care Med

PURPOSE: The mechanisms for persistent and progressive loss of myocardial function in advanced heart failure (HF) remain incompletely characterized. In the current study, we sought to determine the impact of TGF-β on fibroblasts transcriptional profiles and assess if exosomes from TGF-β treated fibroblasts could induce a heart failure phenotype in co-cultured cardiomyocytes.

METHOD: Normal heart fibroblasts were treated with TGF-β with a final conc. of 2.5 ng/ml in serum free media. HF fibroblasts were also obtained from patients undergoing implantation of left ventricular assist devices. Exosomes were collected using three-step ultracentrifugation. Cardiomyocytes were co-cultured with exosomes from TGF-β-treated, HF and …

Smoking causes chronic obstructive pulmonary disease (COPD). Though recent studies identified a COPD metabolomic signature in blood, no large studies examine the metabolome in bronchoalveolar lavage (BAL) fluid, a more direct representation of lung cell metabolism. We performed untargeted liquid chromatography-mass spectrometry (LC-MS) on BAL and matched plasma from 115 subjects from the SPIROMICS cohort. Regression was performed with COPD phenotypes as the outcome and metabolites as the predictor, adjusted for clinical covariates and false discovery rate. Weighted gene co-expression network analysis (WGCNA) grouped metabolites into modules which were then associated with phenotypes. K-means clustering grouped similar subjects. We detected …

It's More Than Low Bmi: Prevalence Of Cachexia And Associated Mortality In Copd, Merry-Lynn N. Mcdonald, Emiel F.M. Wouters, Erica Rutten, Richard Casaburi, Stephen I. Rennard, David A. Lomas, Marcas Bamman, Bartolome Celli, Alvar Agusti, Ruth Tal-Singer, Craig P. Hersh, Mark Dransfield, Edwin K. Silverman

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Cachexia is associated with increased mortality risk among chronic obstructive pulmonary disease (COPD) patients. However, low body mass index (BMI) as opposed to cachexia is often used, particularly when calculating the BODE (BMI, Obstruction, Dyspnea and Exercise) index. For this reason, we examined mortality using a consensus definition and a weight-loss definition of cachexia among COPD cases and compared two new COPD severity indices with BODE.

METHODS: In the current report, the consensus definition for cachexia incorporated weight-loss > 5% in 12-months or low BMI in addition to 3/5 of decreased muscle strength, fatigue, anorexia, low FFMI and inflammation. The …

Journal Articles: Pulmonary & Critical Care Med

Asthma and chronic obstructive pulmonary disease (COPD) have overlapping clinical features and share pathobiological mechanisms but are often considered distinct disorders. Prospective, observational studies across asthma, COPD and asthma-COPD overlap are limited. NOVELTY is a global, prospective observational 3-year study enrolling ∼12 000 patients ≥12 years of age from primary and specialist clinical practices in 19 countries (ClinicalTrials.gov identifier: NCT02760329). NOVELTY's primary objectives are to describe patient characteristics, treatment patterns and disease burden over time, and to identify phenotypes and molecular endotypes associated with differential outcomes over time in patients with a diagnosis/suspected diagnosis of asthma and/or COPD. NOVELTY …

Mold, Allergic Diseases And Asthma: Assessing The Validity And Usefulness Of Indoor Air Sampling As A Tool In Providing Health Protective Advice To Occupants, William M. Sothern

Dissertations and Theses

Background: Asthma is a major health problem throughout the world, disproportionately affecting occupants of low-income housing, and exposure to damp and moldy living conditions is recognized as a significant risk factor for asthma and other respiratory diseases. However, there are no authoritative health guidance values (HGV's) for airborne mold, and current scientific thought holds that the establishment of such guidelines is not practicable. Nonetheless, environmental practitioners take air samples for mold as a routine component of their indoor environmental investigations and use the laboratory results as a tool together with other findings to guide recommendations for health protective actions. The …

Monocytes And Monocyte-Derived Antigen-Presenting Cells Have Distinct Gene Signatures In Experimental Model Of Multiple Sclerosis, Kelly L. Monaghan, Wen Zheng, Gangqing Hu, Edwin C. K. Wan

Faculty & Staff Scholarship

Multiple sclerosis (MS) is a chronic inflammatory disease mediated by a complex interaction between the autoreactive lymphocytes and the effector myeloid cells within the central nervous system (CNS). In a murine model of MS, experimental autoimmune encephalomyelitis (EAE), Ly6Chi monocytes migrate into the CNS and further differentiate into antigen-presenting cells (APCs) during disease progression. Currently, there is no information about gene signatures that can distinguish between monocytes and the monocyte-derived APCs. We developed a surface marker-based strategy to distinguish between these two cell types during the stage of EAE when the clinical symptoms were most severe, and performed transcriptome analysis …
