Mental Health Stigma As A Barrier To Care, Whitney Grant

Regis University Student Publications (comprehensive collection)

Abstract

Mental health stigma is a major barrier to care. The mental health stigma as a problem is relevant due to its influence on increasing the burden of mental health issues due to a lack of help-seeking, contributing to increased healthcare costs, and increasing adverse health outcomes. Currently there is no action consistently taken to assess or address this stigma in the primary care setting. Healthcare professionals can help to reduce the perceptions of stigma and lessen stigma as a barrier to care. A quality improvement project was implemented to evaluate if an education intervention by a primary care provider …

Pgc-1Α Activation To Enhance Macrophage Immune Function In Mycobacterial Infections, Joel R. Frandsen, Zhihong Yuan, Brahmchetna Bedi, Zohra Prasla, Seoung-Ryoung Choi, Prabagaran Narayanasamy, Ruxana Sadikot

Journal Articles: Pathology and Microbiology

Nontuberculous Mycobacteria (NTM) are a heterogeneous group of environmental microorganisms with distinct human pathogenesis. Their incidence and prevalence are rising worldwide, due in part to elevated antimicrobial resistance which complicates treatment and potential successful outcomes. Although information exists on the clinical significance of NTMs, little is known about host immune response to infection. NTM infections alter macrophage mitochondrial capacity and decrease ATP production, efficient immune response, and bacterial clearance. Transcription factor peroxisome proliferator activated receptor (PPAR) γ coactivator-1α (PGC-1α) is a master regulator of mitochondrial biogenesis, influencing metabolism, mitochondrial pathways, and antioxidant response. Mitochondrial transcription factor A (TFAM) is a …

An Observational Study Of Discourse Tasks And Running Speech Sampling In The Assessment Of Paediatric Voice Quality, Victoria Reynolds, Kristin Scavo-Smith, Kate Oteng-Bediako, Sophie Scanlon

Speech-Language Pathology Faculty Publications

Introduction

Running speech sampling is an essential component of a paediatric voice evaluation, in that it should provide the examiner with a representative vocal sample of the child's everyday voice use outside of the clinic setting. Current speech sampling practices, consisting of reading tasks, informal conversation sampling and the voice question ('Tell me about your voice problem'), may not elicit consistent samples or samples of sufficient length to allow the examiner to make a reliable and valid judgement about vocal quality. The aim of this study is to compare the voice quality of children produced in response to existing running …

Staphylococcus Aureus Encodes Four Differentially Regulated Pyruvate Transporters, Jennifer L. Endres, Cleofes Sarmiento, William Xiao, Marat R. Sadykov, Kenneth W. Bayles, Mckenzie K. Lehman

Journal Articles: Pathology and Microbiology

The success of Staphylococcus aureus as a pathogen is attributable, in part, to its ability to exploit the diverse nutrient sources available during infection. Critical to this success are the pathways involving pyruvate that serve as a nexus for energy production, oxidative metabolism, and biosynthetic processes. When available, bacteria acquire pyruvate from the environment to fuel growth. Recently, LrgAB was identified as a pyruvate transporter under microaerobic conditions, leading us to speculate that S. aureus encodes other pyruvate transporters that are active during aerobic growth. In this study, we used the toxic pyruvate analog, 3-fluoropyruvic acid (3-FP), to isolate mutants …

Efficacy Of Deferoxamine Mesylate In Serum And Serum-Free Media: Adult Ventral Root Schwann Cell Survival Following Hydrogen Peroxide-Induced Cell Death, Yee Hang Ethan Ma, Abhinay R. Putta, Cyrus H. H. Chan, Stephen R. Vidman, Paula V. Monje, Giles W. Plant

Neurosurgery Faculty Publications

Schwann cell (SC) transplantation shows promise in treating spinal cord injury as a pro-regenerative agent to allow host endogenous neurons to bridge over the lesion. However, SC transplants face significant oxidative stress facilitated by ROS in the lesion, leading to poor survival. deferoxamine mesylate (DFO) is a neuroprotective agent shown to reduce H₂O₂-induced cell death in serum-containing conditions. Here we show that DFO is not necessary to induce neuroprotection under serum-free conditions by cell survival quantification and phenotypic analysis via immunohistochemistry, Hif1α and collagen IV quantification via whole cell corrected total cell fluorescence, and cell death …
