Food Scan: A Yelp For Dietary Restrictions, Andrew M. Bauer, Charlie Story, Curren Taber

Student Scholar Symposium Abstracts and Posters

Food restrictions pose a serious issue for Chapman students, with consequences as extreme as anaphylactic shock and death. Our team started the Food Scan project with a simple goal of streamlining how individuals with dietary restrictions find safe places to eat or buy food. The project name highlights our intention to clarify restaurant menu items for users by displaying important allergen and dietary information. Using Human-Computer Interaction methods, our team chose to develop a technology that is usable, effective, enjoyable, and inclusive by involving users during the entire design process. By integrating multimodal interfaces (including speech to text inputs), we …

Penicillin Allergy Assessment And Skin Testing In The Outpatient Setting, Wesley D. Kufel, Julie Ann Justo, P. Brandon Bookstaver, Lisa M. Avery

Faculty Publications

Penicillin allergies are among of the most commonly reported allergies, yet only 10% of these patients are truly allergic. This leads to potential inadvertent negative consequences for patients and makes treatment decisions challenging for clinicians. Thus, allergy assessment and penicillin skin testing (PST) are important management strategies to reconcile and clarify labeled penicillin allergies. While PST is more common in the inpatient setting where the results will immediately impact antibiotic management, this process is becoming of increasing importance in the outpatient setting. PST in the outpatient setting allows clinicians to proactively de-label and educate patients accordingly so beta-lactam antibiotics may …

Penicillin Allergy Skin Testing In The Inpatient Setting, Julie Ann Justo, Wesley D. Kufel, Lisa Avery, P. Brandon Bookstaver

Faculty Publications

The consequences of a documented penicillin allergy in the medical record are especially troublesome in acutely ill, hospitalized patients. A penicillin allergy label may lead to alternative or second line therapies resulting in adverse drug events, negative clinical outcomes and increased costs. Reconciling penicillin allergies is a necessity to facilitate early, optimal therapy and is a shared responsibility among the healthcare team. Penicillin skin testing (PST) has been utilized successfully in hospitalized patients to de-label erroneous penicillin allergies and optimize antibiotic therapy. This targeted review aims to discuss the practical development and implementation of PST in the inpatient setting. This …

Quinolone Allergy, Edoabasi U. Mcgee, Essie Samuel, Bernadett Boronea, Nakoasha Dillard, Madison N Milby, Susan J Lewis

PCOM Scholarly Papers

Quinolones are the second most common antibiotic class associated with drug-induced allergic reactions, but data on quinolone allergy are scarce. This review article discusses the available evidence on quinolone allergy, including prevalence, risk factors, diagnosis, clinical manifestations, cross-reactivity, and management of allergic reactions. Although the incidence of quinolone allergy is still lower than beta-lactams, it has been increasingly reported in recent decades, most likely from its expanded use and the introduction of moxifloxacin. Thorough patient history remains essential in the evaluation of quinolone allergy. Many diagnostic tools have been investigated, but skin tests can yield false-positive results and in vitro …

Antimicrobial Stewardship: Staff Nurse Knowledge And Attitudes, Katreena Collette Merrill, Sandra Forsyth Hanson, Sharon Sumner, Todd Vento, John Veillette, Brandono Webb

Faculty Publications

Background: Registered nurses are uniquely qualified to augment antimicrobial stewardship (AS) processes. However, the role of nursing in AS needs further development. More information is needed regarding gaps in registered nurse knowledge, attitudes toward AS, and how infection preventionists can help.

Methods: An online descriptive survey was deployed to a convenience sample of approximately 2,000 nurses at the bedside. The survey included 15 questions addressing: (1) overall knowledge of AS; (2) antimicrobial delivery; (3) knowledge and attitudes regarding antimicrobial use; (4) antimicrobial resistance; and (5) antimicrobial resources and education.

Results: Three hundred sixteen staff nurses from 3 hospitals (15.8%) responded …

Metal Nanomaterials: Immune Effects And Implications Of Physicochemical Properties On Sensitization, Elicitation, And Exacerbation Of Allergic Disease, Katherine A. Roach, Aleksandr B. Stefaniak, Jenny R. Roberts

Faculty & Staff Scholarship

The recent surge in incorporation of metallic and metal oxide nanomaterials into consumer products and their corresponding use in occupational settings have raised concerns over the potential for metals to induce size-specific adverse toxicological effects. Although nano-metals have been shown to induce greater lung injury and inflammation than their larger metal counterparts, their size-related effects on the immune system and allergic disease remain largely unknown. This knowledge gap is particularly concerning since metals are historically recognized as common inducers of allergic contact dermatitis, occupational asthma, and allergic adjuvancy. The investigation into the potential for adverse immune effects following exposure to …

Characterization And Relative Quantitation Of Wheat, Rye, And Barley Gluten Protein Types By Liquid Chromatography–Tandem Mass Spectrometry, Barbara Lexhaller, Michelle L. Colgrave, Katharina A. Scherf

Research outputs 2014 to 2021

The consumption of wheat, rye, and barley may cause adverse reactions to wheat such as celiac disease, non-celiac gluten/wheat sensitivity, or wheat allergy. The storage proteins (gluten) are known as major triggers, but also other functional protein groups such as α-amylase/trypsin-inhibitors or enzymes are possibly harmful for people suffering of adverse reactions to wheat. Gluten is widely used as a collective term for the complex protein mixture of wheat, rye or barley and can be subdivided into the following gluten protein types (GPTs): α-gliadins, γ-gliadins, ω5-gliadins, ω1,2-gliadins, high- and low-molecular-weight glutenin subunits of wheat, ω-secalins, high-molecular-weight secalins, γ-75k-secalins and γ-40k-secalins …
