The Dynamics Of Power And Psychological Safety On Team Cohesion During Interprofessional Simulation-Based Education, Nital Appelbaum

Health Sciences Education Symposium

Healthcare team functioning requires coordination and collaboration between multiple practitioners towards a common goal of delivering safe and quality patient care (Lemieux-Charles & McGuire, 2006). Communication patterns, leadership, mutual support, and situation monitoring are all processes of effective teams (Weaver et al, 2010). However, despite the growing focus on developing interprofessional teams, minimal focus is given to the contextual and cultural forces influencing healthcare team functioning. Negative relationships amongst providers can affect teams in clinical settings, which in turn can undermine patient safety (Carpenter, 1995). Sources of poor team cohesion can be rooted in unequal distributions of power and the …

The First Five Minutes: Enhancing Simulation Education For First-Year Pediatric Residents, Megan E. Coe

Health Sciences Education Symposium

We are looking at the feasibility of redesigning the existing simulation education for first-year residents within the Children’s Hospital of Richmond at VCU’s pediatric residency program to increase learning opportunities and to enhance exposure to pediatric medical emergencies. Novel simulation scenarios were designed to provide an introduction to managing the first five minutes of commonly encountered emergencies on the inpatient wards. These shortened simulations allow for educational objectives to be tailored to the expected knowledge and responsibilities of first-year residents.

Proteomic Approach For Extracting Cytoplasmic Proteins From Streptococcus Sanguinis Using Mass Spectrometry, Fadi Elrami, Kristina Nelson, Ping Xu

Philips Institute for Oral Health Research Publications

Streptococcus sanguinis is a commensal and early colonizer of oral cavity as well as an opportunistic pathogen of infectious endocarditis. Extracting the soluble proteome of this bacterium provides deep insights about the physiological dynamic changes under different growth and stress conditions, thus defining “proteomic signatures” as targets for therapeutic intervention. In this protocol, we describe an experimentally verified approach to extract maximal cytoplasmic proteins from Streptococcus sanguinis SK36 strain. A combination of procedures was adopted that broke the thick cell wall barrier and minimized denaturation of the intracellular proteome, using optimized buffers and a sonication step. Extracted proteome was quantitated …

Slowly Cycling Rho Kinase-Dependent Actomyosin Cross-Bridge "Slippage" Explains Intrinsic High Compliance Of Detrusor Smooth Muscle, Christopher J. Neal, Jia B. Lin, Tanner Hurley, Amy S. Miner, John E. Speich, Adam P. Klausner, Paul H. Ratz

Biochemistry and Molecular Biology Publications

Biological soft tissues are viscoelastic because they display timeindependent pseudoelasticity and time-dependent viscosity. However, there is evidence that the bladder may also display plasticity, defined as an increase in strain that is unrecoverable unless work is done by the muscle. In the present study, an electronic lever was used to induce controlled changes in stress and strain to determine whether rabbit detrusor smooth muscle (rDSM) is best described as viscoelastic or viscoelastic plastic. Using sequential ramp loading and unloading cycles, stress-strain and stiffness-stress analyses revealed that rDSM displayed reversible viscoelasticity, and that the viscous component was responsible for establishing a …

Epigenetic Silencing Of Socs3 Expression Contributes To Fibrosis In Crohn’S Disease, Emily T. Marshall, Chao Li, John K. Kuemmerle

MD Student Summer Research Fellowship Program Posters

Identified risk polymorphisms affecting the Jak-STAT3 pathway in patients with Crohn’s disease could affect TGF-β1 and collagen I expression and in the pathway’s negative regulator, SOCS3. Genetic factors, however, account for only ~25% of disease. Epigenetic events also shape gene expression. Recent experiments showed that autocrine IL-6 production in mesenchymal cells, subepithelial myofibroblasts (SEMF) and muscle cells, of patients with fibrostenotic Crohn’s disease causes sustained Jak-STAT3 activity, excess TGF-β1 and Collagen I production and fibrosis. SOCS3 paradoxically decreased in these cells. We now identify epigenetic mechanisms that silence SOCS3 expression in SEMF of patients with fibrostenotic Crohn’s disease. In a …

Rare Mutations And Potentially Damaging Missense Variants In Genes Encoding Fibrillar Collagens And Proteins Involved In Their Production Are Candidates For Risk For Preterm Premature Rupture Of Membranes, Bhavi P. Modi, Maria E. Teves, Laurel N. Pearson, Hardik I. Parikh, Piya Chaemsaithong, Nihar U. Sheth, Timothy P. York, Roberto Romero, Jerome F. Strauss

Human and Molecular Genetics Publications

Preterm premature rupture of membranes (PPROM) is the leading identifiable cause of preterm birth with ~ 40% of preterm births being associated with PPROM and occurs in 1% - 2% of all pregnancies. We hypothesized that multiple rare variants in fetal genes involved in extracellular matrix synthesis would associate with PPROM, based on the assumption that impaired elaboration of matrix proteins would reduce fetal membrane tensile strength, predisposing to unscheduled rupture. We performed whole exome sequencing (WES) on neonatal DNA derived from pregnancies complicated by PPROM (49 cases) and healthy term deliveries (20 controls) to identify candidate mutations/variants. Genotyping for …

Breastfeeding After Gestational Diabetes: Does Perceived Benefits Mediate The Relationship?, Jordyn T. Wallenborn, Robert A. Perera, Saba W. Masho

Family Medicine and Population Health Publications

Introduction. Breastfeeding is recognized as one of the best ways to decrease infant mortality and morbidity. However, women with gestational diabetes mellitus (GDM) may have breastfeeding barriers due to the increased risk of neonatal and pregnancy complications. While the prevalence of GDM is increasing worldwide, it is important to understand the full implications of GDM on breastfeeding outcomes.The current study aims to investigate the (1) direct effect of GDM on breastfeeding duration and (2) indirect effect of GDM on breastfeeding duration through perceived benefits of breastfeeding. Methods. Prospective cohort data from the Infant Feeding and Practices Study II was analyzed …

Do Successive Preterm Births Increase The Risk Of Postpartum Depressive Symptoms?, Timothy O. Ihongbe, Saba W. Masho

Family Medicine and Population Health Publications

Background. Postpartum depression and preterm birth (PTB) are major problems affecting women’s health. PTB has been associated with increased risk of postpartum depressive symptoms (PDS). However, it is unclear if PTB in women with a prior history of PTB is associated with an incremental risk of PDS. This study aims to determine if PTB in women with a prior history of PTB is associated with an incremental risk of PDS. Methods. Data come from the 2009–2011 national Pregnancy Risk Assessment Monitoring System. Study sample included 55,681 multiparous women with singleton live births in the index delivery.

Interleukin-18 Mediates Cardiac Dysfunction Induced By Western Diet Independent Of Obesity And Hyperglycemia In The Mouse, S Carbone, P J H Lee, A G Mauro, E Mezzaroma, R Buzzetti, B Van Tassell, A Abbate, S Toldo

Family Medicine and Population Health Publications

Obesity and diabetes are independent risk factors for heart failure and are associated with the consumption of diet rich in saturated fat and sugar, Western diet (WD), known to induce cardiac dysfunction in the mouse through incompletely characterized inflammatory mechanisms. We hypothesized that the detrimental cardiac effects of WD are mediated by interleukin-18 (IL-18), proinflammatory cytokine linked to cardiac dysfunction. C57BL/6J wild-type male mice and IL-18 knockout male mice were fed highsaturated fat and high-sugar diet for 8 weeks. We measured food intake, body weight and fasting glycemia. We assessed left ventricular (LV) systolic and diastolic function by Doppler echocardiography …

Twamley, Helene Ugelstad, Øystein Spjelkavik, Marianne Løvstad, Nada Andelic

Family Medicine and Population Health Publications

Background

A considerable proportion of patients with mild to moderate traumatic brain injury (TBI) experience long-lasting somatic, cognitive, and emotional symptoms that may hamper their capacity to return to work (RTW). Although several studies have described medical, psychological, and work-related factors that predict RTW after TBI, well-controlled intervention studies regarding RTW are scarce. Furthermore, there has traditionally been weak collaboration among health-related rehabilitation services, the labor and welfare sector, and workplaces.

Methods/design

This study protocol describes an innovative randomized controlled trial in which we will explore the effect of combining manualized cognitive rehabilitation (Compensatory Cognitive Training [CCT]) and supported employment …

Structural Modeling And Functional Analysis Of The Essential Ribosomal Processing Protease Prp From Staphylococcus Aureus, Erin A. Wall, Adam L. Johnson, Darrell L. Peterson, Gail E. Christie

Microbiology and Immunology Publications

In Firmicutes and related bacteria, ribosomal large subunit protein L27 is encoded with a conserved N-terminal extension that is removed to expose residues critical for ribosome function. Bacteria encoding L27 with this N-terminal extension also encode a sequence-specific cysteine protease, Prp, which carries out this cleavage. In this work, we demonstrate that L27 variants with an un-cleavable N-terminal extension, or lacking the extension (pre-cleaved), are unable to complement an L27 deletion in Staphylococcus aureus. This indicates that N-terminal processing of L27 is not only essential but possibly has a regulatory role. Prp represents a new clade of previously uncharacterized cysteine …

Tetr Family Regulator Brpt Modulates Biofilm Formation In Streptococcus Sanguinis, Jinlin Liu, Victoria N. Stone, Xiuchun Ge, Madison Tang, Fadi Elrami, Ping Xu

Microbiology and Immunology Publications

Biofilms are a key component in bacterial communities providing protection and contributing to infectious diseases. However, mechanisms involved in S. sanguinis biofilm formation have not been clearly elucidated. Here, we report the identification of a novel S. sanguinis TetR repressor, brpT (Biofilm Regulatory Protein TetR), involved in biofilm formation. Deletion of brpT resulted in a significant increase in biofilm formation. Interestingly, the mutant accumulated more water soluble and water insoluble glucans in its biofilm compared to the wild-type and the complemented mutant. The brpT mutation led to an altered biofilm morphology and structure exhibiting a rougher appearance, uneven …

Identification Of Naegleria Fowleri Proteins Linked To Primary Amoebic Meningoencephalitis, Melissa Jamerson, Jacqueline A. Schmoyer, Jay Park, Francine Marciano-Cabral, Guy A. Cabral

Microbiology and Immunology Publications

Naegleria fowleri (N. fowleri) causes primary amoebic meningoencephalitis, a rapidly fatal disease of the central nervous system. N. fowleri can exist in cyst, flagellate or amoebic forms, depending on environmental conditions. The amoebic form can invade the brain following introduction into the nasal passages. When applied intranasally to a mouse model, cultured N. fowleri amoebae exhibit low virulence. However, upon serial passage in mouse brain, the amoebae acquire a highly virulent state. In the present study, a proteomics approach was applied to the identification of N. fowleri amoeba proteins whose expression was associated with the highly virulent state …

Towards A Not Obtrusive Low Cost Biosystem To Assess Risk Perception In Workplace Through Stress Detection, Emanuele Bellini, Serena Benevenuti, Chiara Batistini

H-Workload 2017: Models and Applications (Works in Progress)

The main aim of the article is to build a method to assess risk perception in real time in order to early detect and prevent risk behaviors and possible human errors. To this end, the relation between mental workload and stress as critical factors affecting risk perception has been investigated. In particular the mental-physical activation generated by an increment of the workload has the effect of reducing the resources needed to perceive risk increasing the worker vulnerability. The complexity of the stress phenomenon suggested the adoption of an integrated view. The Functional Model has been adopted to for its holistic …
