Managing Pediatric Atopic Dermatitis In The Allergy Clinic: Use Of An Eczema Action Plan To Improve Caregiver Understanding And Self-Efficacy, A Pilot Study, Danielle Hubacek 2021 University of San Diego

Managing Pediatric Atopic Dermatitis In The Allergy Clinic: Use Of An Eczema Action Plan To Improve Caregiver Understanding And Self-Efficacy, A Pilot Study, Danielle Hubacek

Doctor of Nursing Practice Final Manuscripts

Eczema, or atopic dermatitis, is a complex and chronic condition that affects approximately 10% of children throughout the United States (Brown et al., 2018). The American Academy of Allergy Asthma & Immunology (AAAAI) (2017) estimates the average cost of eczema management for each patient is approximately $3,302 per year. The complex nature of atopic dermatitis indicates a need for individualized treatment plans. Research has shown that standardized patient teaching, written education materials, and Eczema Action Plans (EAP) reinforce patient teaching, parental understanding, and improve quality of life. This evidence-based practice (EBP) project introduces the use of a written Eczema Action ...

Importance Of Understanding Genetic Predisposition, Andrew Carter

Thinking Matters Symposium

Hypersensitivity reactions can be sudden and are often fatal. Many of these reactions occur as a result of allergies to prescribed medication. Adverse drug reactions or (ADR’s) were show in a recent study to affect over 6% of hospitalized patients and resulted in over 100,000 deaths a year in the US alone. This poster will review the importance of understanding genetic predisposition, through articles about possible genetic causes of allergies to penicillin and other beta-lactams. Changes in a specific HLA gene located on chromosome 6 showed a correlation to penicillin reactions in over 600,000 participants. Another study ...

Journal of Mind and Medical Sciences

Starting from a new organic sunscreen synthesized in our laboratory by the condensation of sodium salt of the p-aminosalicylic acid with 2,6 – dichloroacetanilide, efficient cosmetic formulation with broad photoprotective properties was obtained by using the new compound as organic UV filter, metal oxides as inorganic filters, and vegetable extracts, oils and other ingredients with emollient, protective, and moisturizing effect. After showing the lack of toxicity of the new compound, in order to reduce the amount of UV filter used, it was encapsulated into nanostructured lipid carriers (NLCs). The final cream has demonstrated good qualities for skin application, possessing suitable ...


Novel Use Of Fresh Frozen Plasma In Treating Hereditary Angioedema: A Success Story From Pakistan, Amber Sabeen Ahmed, Sidra Fayyaz 2020 Aga Khan University

Novel Use Of Fresh Frozen Plasma In Treating Hereditary Angioedema: A Success Story From Pakistan, Amber Sabeen Ahmed, Sidra Fayyaz

Section of Internal Medicine

Hereditary angioedema (HAE) due to a C1-esterase inhibitor(C1-INH) deficiency is a rare and potentially life-threatening disorder. It is characterized by an episodic and self-limiting increase in vascular permeability. The condition manifests itself as recurrent attacks of swelling in any part of the body. The angioedema can cause the involvement of the respiratory tract, skin, and gastrointestinal tract. Laryngeal involvement can make the condition life-threatening. It does not respond well to conventional angioedema therapy of steroids, adrenaline, and antihistamines. The targeted therapy for HAE consists of plasma-derived or recombinant C1-INH, ecallantide, and icatibant or bradykinin receptor antagonist. In the absence ...

While mammals tend to repair injuries, other adult vertebrates like salamanders and fish regenerate damaged tissue. One prominent hypothesis offered to explain an inability to regenerate complex tissue in mammals is a bias during healing toward strong adaptive immunity and inflammatory responses. Here we directly test this hypothesis by characterizing part of the immune response during regeneration in spiny mice (Acomys cahirinus and Acomys percivali) vs. fibrotic repair in Mus musculus. By directly quantifying cytokines during tissue healing, we found that fibrotic repair was associated with a greater release of pro-inflammatory cytokines (i.e., IL-6, CCL2, and CXCL1) during acute ...

Automatic Recognition, Segmentation, And Sex Assignment Of Nocturnal Asthmatic Coughs And Cough Epochs In Smartphone Audio Recordings: Observational Field Study, Filipe Barata, Peter Tinschert, Frank Rassouli, Claudia Steurer-Stey, Elgar Fleisch, Milo Puhan, Martin Brutsche, David Kotz, Tobias Kowatsch

Dartmouth Scholarship

Background: Asthma is one of the most prevalent chronic respiratory diseases. Despite increased investment in treatment, little progress has been made in the early recognition and treatment of asthma exacerbations over the last decade. Nocturnal cough monitoring may provide an opportunity to identify patients at risk for imminent exacerbations. Recently developed approaches enable smartphone-based cough monitoring. These approaches, however, have not undergone longitudinal overnight testing nor have they been specifically evaluated in the context of asthma. Also, the problem of distinguishing partner coughs from patient coughs when two or more people are sleeping in the same room using contact-free audio ...

Convalescent Plasma In Covid-19, Ranjit S. Banwait, Joshua K. Salabei, Troy J. Fishman, Uma G. Iyer

HCA Healthcare Journal of Medicine

The recent pandemic of SARS-CoV-2, which causes novel coronavirus disease 2019 (Covid-19), has had devastating impact on a global and national scale. In order to overcome this outbreak it is imperative we find treatments that are safe and effective. To date, no definitive treatment is available that can curtail the spread of this viral syndrome. Convalescent plasma (CP) is one such option that has repeatedly served as an important tool in treatment of various bacterial and viral infections, especially in the setting of no specific antimicrobial or vaccination against an infectious disease. Herein, we review the history of CP, prior ...


In Vivo Mechanisms Of Natural Killer Cell Tolerance, Michael Bern 2020 Washington University in St. Louis

In Vivo Mechanisms Of Natural Killer Cell Tolerance, Michael Bern

Arts & Sciences Electronic Theses and Dissertations

Natural killer (NK) cells are cytotoxic innate immune cells that provide protection from pathogens and tumors. To carry out these functions, NK cells must distinguish between healthy and unhealthy self-cells. Inability to recognize stressed cells would lead to a failure of NK-cell immunity whereas inability to identify healthy cells could lead to NK-cell autoimmunity. It remains unclear, however, how NK cells are able to distinguish healthy and unhealthy self-cells with a limited repertoire of germline-encoded receptors. The "missing-self" hypothesis proposes that NK cells identify stressed cells by their reduced expression of MHC class I (MHC-I) that is almost ubiquitously expressed ...


Signaling Mechanisms In Adaptive Immunity, Saravanan Raju 2020 Washington University in St. Louis

Signaling Mechanisms In Adaptive Immunity, Saravanan Raju

Arts & Sciences Electronic Theses and Dissertations

The adaptive immune response consists of interplay between CD4 T cells, CD8 T cells, and B cells which function in control of pathogen in the host. T cells responding via their TCR express cytokines and costimulatory molecules that support direct effector activity and also promote high-affinity antibody generation through augmenting of B cell responses. However, the molecular components that contribute T cell function to balance viral control and the potential for host damage are incompletely understood. In this work, we establish a role for the adaptor molecule CD2AP in modulation of CD4 T cell responses to chronic LCMV infection in ...


Identification And Characterization Of A Novel Non-Homologous End Joining Factor Mri, Putzer Joseph Hung 2020 Washington University in St. Louis

Identification And Characterization Of A Novel Non-Homologous End Joining Factor Mri, Putzer Joseph Hung

Arts & Sciences Electronic Theses and Dissertations

Non-homologous end joining (NHEJ) is the predominant DNA double-strand break (DSB) repair pathway in G1-phase cells. In particular, developing lymphocytes utilize NHEJ to repair physiologic DSBs generated during the processes of antigen receptor gene assembly and class-switch recombination (CSR). Thus, proper regulation of NHEJ is important not only for immune repertoire diversification, but also for the prevention of chromosomal translocations or deletions that can arise from misrepaired DSBs. The XRCC4-like factor (XLF) has been strongly implicated in promoting NHEJ, presumably by tethering broken DNA ends together in a sleeve-like complex, but its necessity appears to be cell context-dependent. While XLF ...


Metabolic Requirements Of Nk Cell Responses To Viral Infection, Annelise Yoo Mah-Som 2020 Washington University in St. Louis

Metabolic Requirements Of Nk Cell Responses To Viral Infection, Annelise Yoo Mah-Som

Arts & Sciences Electronic Theses and Dissertations

In recent years, the field of immunometabolism – the study of how specific changes in cellular metabolism regulate the function of diverse immune cell types—has grown exponentially. Several in vitro studies have examined the metabolic regulation of natural killer (NK) cells, which are first responders for viral infection and malignant transformation; however, much less is known regarding the role of metabolism in directing NK cell responses in vivo, such as during viral infection. In order to examine how NK cell antiviral function is regulated in vivo, we used a wellcharacterized infection with murine cytomegalovirus (MCMV) to assess NK cell cytokine ...


Dendritic Cell Development And Function, Vivek Durai 2020 Washington University in St. Louis

Dendritic Cell Development And Function, Vivek Durai

Arts & Sciences Electronic Theses and Dissertations

Dendritic cells (DCs) are a group of immune cells that include both classical dendritic cells (cDCs) and plasmacytoid dendritic cells (pDCs). cDCs are further comprised of two distinct subsets, cDC1s and cDC2s, which play critical roles in the initiation of innate and adaptive immune responses. Understanding how these lineages develop and function is therefore paramount. All DCs require the receptor tyrosine kinase Flt3 and its ligand Flt3L for their development, but the loss of Flt3L in mice leads to a more severe DC deficiency than does the loss of Flt3. This has led to speculation that Flt3L can bind to ...


The Enzymatic Function Of The Tir Domain: From Axon Degeneration To Innate Immunity, Kow Essuman 2020 Washington University in St. Louis

The Enzymatic Function Of The Tir Domain: From Axon Degeneration To Innate Immunity, Kow Essuman

Arts & Sciences Electronic Theses and Dissertations

The Toll/Interleukin-1 Receptor (TIR) domain is an evolutionarily ancient protein domain conserved from bacteria to eukaryotes, and is an essential signaling component of innate immunity pathways. In animal innate immunity, TIR domains have primarily been described for their scaffolding function in assembling protein complexes in host defense. In plant immunity, TIR domains are key components of the intracellular Nucleotide Binding Leucine rich repeat (NLR) immune receptors that confer resistance to pathogens. These NLR receptors trigger cell death and an immune response upon activation, but their mechanism has remained elusive. In bacteria, TIR domain proteins have been suggested to function ...


Effects Of Agonistic Anti-Cd137 Antibody On Chikungunya Virus Infection And B Cell Responses, Jun Hong 2020 Washington University in St. Louis

Effects Of Agonistic Anti-Cd137 Antibody On Chikungunya Virus Infection And B Cell Responses, Jun Hong

Arts & Sciences Electronic Theses and Dissertations

CD137, a member of the tumor necrosis factor receptor superfamily of cell surface proteins, acts as a costimulatory receptor on T cells, natural killer cells, B cell subsets, and some dendritic cells. Agonistic anti-CD137 monoclonal antibody (MAb) therapy has been combined with other chemotherapeutic agents in human cancer trials. Based on its ability to promote tumor clearance, we hypothesized that anti-CD137 MAb might activate immune responses and resolve chronic viral infections. We evaluated anti-CD137 MAb therapy in a mouse infection model of chikungunya virus (CHIKV), an alphavirus that causes chronic polyarthritis in humans and is associated with reservoirs of CHIKV ...


Epigenetic And Signaling Pathways Regulating The Maintenance Of Cd8 T Cell Identity And Function, Daniel Verbaro 2020 Washington University in St. Louis

Epigenetic And Signaling Pathways Regulating The Maintenance Of Cd8 T Cell Identity And Function, Daniel Verbaro

Arts & Sciences Electronic Theses and Dissertations

In response to infection, antigen specific CD4 and CD8 T cells rapidly divide to provide help to the immune system and promote cytotoxicity of infected cells, respectively. Through this rapid division, CD4 and CD8 T cells maintain silencing of the opposing lineage’s genes, which is essential to acutely eliminating pathogens. However, not all pathogens are acutely eliminated even when silencing is maintained, and the pathogen persists in the presence of activated CD8 T cells. CD8 T cells chronically exposed to antigen are phenotypically different than CD8 T cells acutely exposed to antigen, but CD8 T cell still exert control ...
