BACKGROUND: Sepsis is a potentially fatal systemic inflammatory response syndrome (SIRS) that threatens millions of lives worldwide. Echinococcus granulosus antigen B (EgAgB) is a protein released by the larvae of the tapeworm. This protein has been shown to play an important role in modulating host immune response. In this study we expressed EgAgB as soluble recombinant protein in E. coli (rEgAgB) and explored its protective effect on sepsis.

METHODS: The sepsis model was established by cecal ligation and puncture (CLP) procedure in BALB/c mice. The therapeutic effect of rEgAgB on sepsis was performed by interperitoneally injecting 5 µg rEgAgB in …

Rare cell populations can be challenging to characterize using microfluidic single-cell RNA sequencing (scRNA-seq) platforms. Typically, the population of interest must be enriched and pooled from multiple biological specimens for efficient collection. However, these practices preclude the resolution of sample origin together with phenotypic data and are problematic in experiments in which biological or technical variation is expected to be high (e.g., disease models, genetic perturbation screens, or human samples). One solution is sample multiplexing whereby each sample is tagged with a unique sequence barcode that is resolved bioinformatically. We have established a scRNA-seq sample multiplexing pipeline for mouse retinal …

Rationale: Chronic obstructive pulmonary disease (COPD) is a heterogeneous condition. Objectives: We hypothesized that the unbiased integration of different COPD lung omics using a novel multilayer approach might unravel mechanisms associated with clinical characteristics.

Methods: We profiled mRNA, microRNA and methylome in lung tissue samples from 135 former smokers with COPD. For each omic (layer), we built a patient network on the basis of molecular similarity. The three networks were used to build a multilayer network, and optimization of multiplex modularity was used to identify patient communities across the three distinct layers. Uncovered communities were related to clinical features.

Children In Psychiatric Crises, Elizabeth Mcgarvey, Gabriella Demeo, Jasmine Clark, Carrie Ribbing, Paige Hameister, Sally Hannafon

Nursing Research and EBP Day 2024

Mental illness in children is on the rise and more children are becoming psychiatric boarders while awaiting treatment. Many hospitals lack a separate area to board children in psychiatric crisis who can’t be discharged to home which means that children are housed in the same unit as adult psychiatric patients. This EBP project sought to identify best practices for children experiencing a mental health crisis, but a more thorough review of the literature as well as an evidence synthesis needs to be completed before practice recommendations can be identified.

Nursing Research and EBP Day 2024

Pressure injuries remain a huge concern in both the acute and long term care settings worldwide. It is estimated that nearly 2.5 million people are affected each year by a pressure injury. They contribute to higher costs for care, decrease patient’s quality of life and can increase morbidity and mortality.

This project implemented the use of rounding by both skin care champions and nurse residents for high risk patients, while leadership utilized huddles to reinforce appropriate interventions. Turning and positioning every two hours was endorsed as was daily bathing for patients at high risk for developing pressure injuries.

Roadmap To Address Nursing Recruitment And Retention In Ambulatory Care, Susan Madison, Tiffany Smith Nov 2024

Roadmap To Address Nursing Recruitment And Retention In Ambulatory Care, Susan Madison, Tiffany Smith

Nursing Research and EBP Day 2024

As hospital stays shorten, ambulatory care must expand to meet the increased patient acuity and need for care. Ambulatory care is the entry point for care delivery and the initiator of disease management and wellness (Ulrich, 2019). The ambulatory care system of Rochester Regional Health includes 400 registered nurses, and 600 licensed practical nurses with a nursing turnover rate of 18.75%.

By leveraging technology and innovation in program development, ambulatory-specific programs have been implemented to target nursing staff recruitment and retention, resulting in a 4% decrease in ambulatory nurse turnover rates.

Nurses Busting Burnout: How Self Care Programs Support Nurse Well-Being, Lenard Fernandez, Marguerite Loughrey, Andrea Cooley, Ashley Dilimone, Mariah Luce, Gabriella Rindell

Nursing Research and EBP Day 2024

Nurses working in acute care suffer from high levels of stress, burnout and turnover. Our question: For acute care nurses, what is the effect of self-care program versus no program on moral resilience? A literature review was conducted and results showed that when education on group-based wellness practices was provided, there was increased job satisfaction, moral resilience, and problem solving ability. There were decreases in feelings of burnout, and improved work/life balance. Some studies demonstrated an increase in patient satisfaction. Within Rochester Regional Health, it may not be too difficult to implement group based programs and coaching services.

Alternatively Spliced Map4 Isoforms Have Key Roles In Maintaining Microtubule Organization And Skeletal Muscle Function, Lathan Lucas, Larissa Nitschke, Brandon Nguyen, James A Loehr, George G Rodney, Thomas A Cooper

Faculty, Staff and Students Publications

Skeletal muscle cells (myofibers) are elongated non-mitotic, multinucleated syncytia that have adapted a microtubule lattice. Microtubule-associated proteins (MAPs) play roles in regulating microtubule architecture. The most abundant MAP in skeletal muscle is MAP4. MAP4 consists of a ubiquitous MAP4 isoform (uMAP4), expressed in most tissues, and a striated-muscle-specific alternatively spliced isoform (mMAP4) that includes a 3,180-nucleotide exon (exon 8). To determine the role of mMAP4 in skeletal muscle, we generated mice that lack mMAP4 and express only uMAP4 due to genomic deletion of exon 8. We demonstrate that loss of mMAP4 leads to disorganized microtubule architecture and intrinsic loss of …

Going Against The Family: Perturbation Of A Greenbeard Pathway Leads To Falsebeard Cheating, Peter Lehmann, Mariko Katoh-Kurasawa, Peter Kundert, Gad Shaulsky

Faculty, Staff and Students Publications

Greenbeards facilitate cooperation by encoding a perceptible signal, the ability to detect it, and a tendency to help others that display it. Falsebeards are hypothetical cheaters that display the signal without being altruistic. Despite many examples of greenbeards, evidence for falsebeards is scarce. The Dictyostelium discoideum tgrB1-tgrC1 allorecognition pathway encodes a greenbeard. It allows development, which yields fruiting bodies with altruistic stalks that increase spore dispersal. Here we show that cells lacking rapgapB, a tgrB1-tgrC1 signaling element, cheat by avoiding the stalk fate and generating more spores in chimeras than in pure populations. rapgapB cells cheat only on …

Cyclin E is a regulatory subunit of CDK2 that mediates S phase entry and progression. The cleavage of full-length cyclin E (FL-cycE) to low-molecular weight isoforms (LMW-E) dramatically alters substrate specificity, promoting G1-S cell cycle transition and accelerating mitotic exit. Approximately 70% of triple-negative breast cancers (TNBC) express LMW-E, which correlates with poor prognosis. PKMYT1 also plays an important role in mitosis by inhibiting CDK1 to block premature mitotic entry, suggesting it could be a therapeutic target in TNBC expressing LMW-E. In this study, analysis of tumor samples of patients with TNBC revealed that coexpression of LMW-E and PKMYT1-catalyzed CDK1 …

Faculty, Staff and Student Publications

BACKGROUND: Accurate variant classification and relaying reclassified results to patients is critical for hereditary cancer care delivery. Over a 5- to 10-year period, 6%-15% of variants undergo reclassification. As the frequency of reclassifications increases, the issue of whether, how, when, and which providers should recontact patients becomes important but remains contentious.

METHODS: The authors used inductive thematic analysis to analyze open-ended comments offered by oncologists and genetic counselors (GCs) from a large national survey.

RESULTS: Of the 634 oncologists and cancer GCs, 126 (20%) offered substantive free-text comments. Four thematic areas emerged: 1) ambiguity over professional responsibility to recontact, 2) …

Personalized Composite Dosimetric Score-Based Machine Learning Model Of Severe Radiation-Induced Lymphopenia Among Patients With Esophageal Cancer, Yan Chu, Cong Zhu, Brian P Hobbs, Yiqing Chen, Peter S N Van Rossum, Clemens Grassberger, Degui Zhi, Steven H Lin, Radhe Mohan

Faculty, Staff and Student Publications

Purpose: Radiation-induced lymphopenia (RIL) is common among patients undergoing radiation therapy (RT)' Severe RIL has been linked to adverse outcomes. The severity and risk of RIL can be predicted from baseline clinical characteristics and dosimetric parameters. However, dosimetric parameters, e.g. dose-volume (DV) indices, are highly correlated with one another and are only weakly associated with RIL. Here we introduce the novel concept of "composite dosimetric score" (CDS) as the index that condenses the dose distribution in immune tissues of interest to study the dosimetric dependence of RIL. We derived an improved multivariate classification scheme for risk of grade 4 RIL …
