“Trauma To The Eye” – A Low Fidelity Module For Identifying Retrobulbar Hematoma And Practicing Lateral Canthotomy & Cantholysis, Jared Raikin, Dimitrios Papanagnou, Md, Ronald Hall, Md

Phase 1

Purpose: A retrobulbar hematoma (RH) can cause preventable blindness due to damage of the optic nerve. Due to its relative infrequency in the emergency department, Emergency Medecine (EM) residents have limited experience in recognizing and treating a RH. This paper outlines a simulated scenario that was developed to improve EM residents knowledge in diagnosing a RH and performing an emergent lateral canthotomy and cantholysis (LCC).

Methods: This module used a low fidelity task trainer and case vignette created for EM residents to practice recognizing a RH and perfroming a LCC. Participants took an assessment questionnaire before and after the teaching …

Perceptions Of Centering Pregnancy At Jefferson’S Maternal Addiction Treatment, Education & Research (Mater) Program, Lindsay Caldarone, Ms, Vanessa Short, Phd, Mph

Phase 1

Introduction: Opioid use and misuse, including during pregnancy, is prevalent across the United States. Many women with opioid use disorder (OUD) face multiple barriers to care, including prenatal care.

Phase 1

Purpose: U/S guided peripheral intravenous catheter (PIV) placement is implemented in many clinical settings. Commercially available U/S phantoms are expensive and difficult to alter from stock. Non-commercial phantoms have been described in published literature without data showing which type is more efficacious. The primary objective of this study was to determine efficacy of various non-commercial phantoms for U/S guided PIV placement, while secondary objectives were to characterize the cost and ease of production.

Methods: This prospective observational study trialed six unique phantom models: 1) Amini ballistics gel model, 2) Morrow ballistics gel model, 3) University of California San Diego (UCSD) …

Performance Improvement In Healthcare: Integrating Gilbert's Behavior Engineering Model Within A Just Culture, Candice Freeman, Jill Erin Stefaniak

STEMPS Faculty Publications

Healthcare leadership and department management personnel are tasked with the responsibility of ensuring safe, high-quality patient care delivered by competent and proficient staff. This responsibility often comes in the form of identification of discrepant and erroneous practices that result in subsequent employee disciplinary action process improvement discussions and implementation. This case study presents an example of a sentinel event and how Gilbert's Behavior Engineering Model (BEM) was utilized in the context of a Just Culture to ensure both processes and personnel were adequately supported to meet expected task outcomes.

Law, Structural Racism, And The Covid-19 Pandemic, Ruqaiijah Yearby, Seema Mohapatra

All Faculty Scholarship

Racial and ethnic minorities have always been the most impacted by pandemics because of: disparities in exposure to the virus; disparities in susceptibility to contracting the virus; and disparities in treatment. This article explains how structural racism, the ways in which laws are used to advantage the majority and disadvantage racial and ethnic minorities, has caused these disparities. Specifically, this article focuses on how employment, housing, health care, and COVID-19 relief laws have been manipulated to disadvantage racial and ethnic minorities, making minorities more susceptible to COVID-19 infection and death. This article uses Blumenshine’s 2008 framework to outline how structural …

Structural Discrimination In Covid-19 Workplace Protections, Ruqaiijah Yearby, Seema Mohapatra

All Faculty Scholarship

Workers, who are being asked to risk their health by working outside their homes during the COVID-19 pandemic, need adequate hazard compensation, safe workplace conditions, and personal protective equipment (PPE). Sadly, this is not happening for many essential workers, such as those working in home health care and in the meat processing industry. These workers are not only being unnecessarily exposed to the virus, but they are also not receiving paid sick leave, unemployment benefits, and affordable health care and childcare. The lack of these protections is due to structural discrimination and has disproportionately disadvantaged women of color and low-wage …

The Americans With Disabilities Act And Healthcare Employer-Mandated Vaccinations, Y. Tony Yang, Elizabeth Pendo, Dorit Rubinstein Reiss

All Faculty Scholarship

Battles around workplace vaccination policies often focus on the annual influenza vaccine, but many healthcare employers impose requirements for additional vaccines because of the increased likelihood that employees in this sector will interact with populations at increased risk of acquiring or experiencing harmful sequelae of vaccine-preventable diseases. The federal Centers for Disease Control and Prevention and many states recommend healthcare employees receive numerous vaccines, including measles, mumps, and rubella (“MMR”); tetanus, diphtheria, and pertussis (“Tdap”). However, recent outbreaks of once-eliminated diseases that are now resurgent and the rising antivaccination movement raise questions about how far employers can go to mandate …

The Problem With Relying On Profit-Driven Models To Produce Pandemic Drugs, Ana Santos Rutschman

All Faculty Scholarship

The longstanding problems of relying on a market response to a pandemic are becoming readily apparent in the United States, which has quickly become the epicenter of the COVID-19 outbreak. The problems are particularly pronounced in pharmaceutical markets, where we are pinning our hopes for both cures and vaccines. In previous work we have shown how characteristics of healthcare markets in the United States create a divergence between the private incentives of for-profit companies and public health needs, leading to sub-optimal health outcomes in what is a uniquely market-driven healthcare system. In this Essay, written as the COVID-19 pandemic unfolds, …

Mapping Misinformation In The Coronavirus Outbreak, Ana Santos Rutschman

All Faculty Scholarship

The coronavirus outbreak has sent ripples of fear and confusion across the world. These sentiments—and our collective responses to the outbreak—are made worse by rampant misinformation surrounding the new strain of the virus, COVID-2019. In this post, I survey some of the most pervasive areas of tentacular coronavirus-related misinformation that has proliferated online -- as well as the responses of social media companies like YouTube, Facebook, Pinterest and TikTok that may ultimately prove inadequate given the magnitude of the problem.

Substance Use Disorder, Discrimination, And The Cares Act: Using Disability Law To Strengthen New Protections, Kelly K. Dineen, Elizabeth Pendo

All Faculty Scholarship

The COVID-19 pandemic is having devastating consequences for people with substance use disorders (SUD). SUD is a chronic health condition—like people with other chronic health conditions, people with SUD experience periods of remission and periods of exacerbation and relapse. Unlike people with most other chronic conditions, people with SUD who experience a relapse may face criminal charges and incarceration. They are chronically disadvantaged by pervasive social stigma, discrimination, and structural inequities. People with SUD are also at higher risk for both contracting the SARS-CoV-19 virus and experiencing poorer outcomes. Meanwhile, there are early indications that pandemic conditions have led to …

Protecting The Rights Of People With Disabilities, Elizabeth Pendo

All Faculty Scholarship

One in four Americans — a diverse group of 61 million people — experience some form of disability (Okoro, 2018). On average, people with disabilities experience significant disparities in education, employment, poverty, access to health care, food security, housing, transportation, and exposure to crime and domestic violence (Pendo & Iezzoni, 2019). Intersections with demographic characteristics such as race, ethnicity, gender, and LGBT status, may intensify certain inequities. For example, women with disability experience greater disparities in income, education, and employment (Nosek, 2016), and members of under-served racial and ethnic groups with disabilities experience greater disparities in health status and access …

Medicaid's Vital Role In Addressing Health And Economic Emergencies, Nicole Huberfeld, Sidney Watson

All Faculty Scholarship

Medicaid plays an essential role in helping states respond to crises. Medicaid guarantees federal matching funds to states, which helps with unanticipated costs associated with public health emergencies, like COVID-19, and increases in enrollment that inevitably occur during times of economic downturn. Medicaid’s joint federal/state structure, called cooperative federalism, gives states significant flexibility within federal rules that allows states to streamline eligibility and expand benefits, which is especially important during emergencies. Federal emergency declarations give the secretary of Health and Human Services temporary authority to exercise regulatory flexibility to ensure that sufficient health care is available to meet the needs …

Vaccine Hesitancy: Experimentalism As Regulatory Opportunity, Ana Santos Rutschman, Timothy L. Wiemken

All Faculty Scholarship

This symposium on patient innovation has prompted us to explore problems related to departures from official vaccination schedules. At a time in which vaccine confidence has been plummeting across the world, we argue that a more granular understanding—and ultimately a more finely tuned regulatory framework—is needed to reflect the current behavioral heterogeneity among indicated patients who choose to forego or delay administration of recommended vaccines. In particular, we focus on a phenomenon we term “vaccine staggering:” a departure from vaccination schedules in the form of delays in receiving one or more vaccines, which is motivated by the desire to boost …

Center For Progressive Reform Report: Protecting Workers In A Pandemic--What The Federal Government Should Be Doing, Thomas Mcgarity, Michael C. Duff, Sidney A. Shapiro

All Faculty Scholarship

The "re-opening" of the American economy while the coronavirus that causes COVID-19 is still circulating puts workers at heightened risk of contracting the deadly virus. In some blue-collar industries, the risk is particularly acute because of the inherent nature of the work itself and of the workplaces in which it is conducted. And the risk, for a variety of reasons, falls disproportionately on people of color and low-income workers. With governors stay-at-home orders and other pandemic safety restrictions, Center for Progressive Reform Member Scholars Thomas McGarity, Michael Duff, and Sidney Shapiro examine the federal government's many missed opportunities to stem …

'Terroristic Threats' And Covid-19: A Guide For The Perplexed, Chad Flanders, Courtney Federico, Eric Harmon, Lucas Klein

All Faculty Scholarship

The first few months of the COVID-19 outbreak in the United States saw the rise of a troubling sort of behavior: people would cough or spit on people or otherwise threaten to spread the COVID-19 virus, resulting in panic and sometimes thousands of dollars’ worth of damages to businesses. Those who have been caught doing this — or have filmed themselves doing it — have been charged under so-called “terroristic threat” statutes. But what is a terroristic threat, and is it an appropriate charge in these cases? Surprisingly little has been written about these statutes given their long history and …

Covid-19 And The Conundrum Of Mask Requirements, Robert Gatter, Seema Mohapatra

All Faculty Scholarship

As states begin to loosen their COVID-19 restrictions, public debate is underway about what public health measures are appropriate. Many states have some form of mask-wearing orders to prevent the spread of COVID-19 infection. Public health guidance from the Centers for Disease Control and Prevention and the World Health Organization has conflicted. From a public health point of view, it is not clear what the right answer is. In the absence of directives, individuals are also making their own choices about mask use. At a time when public health measures, like shelter-in-place orders and social distancing, are being used to …

Mechanistic And Functional Shades Of Mucins And Associated Glycans In Colon Cancer, Ramesh Pothuraju, Shiv Ram Krishn, Shailendra K. Gautam, Priya Pai, Koelina Ganguly, Sanjib Chaudhary, Satyanarayana Rachagani, Sukhwinder Kaur, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

Mucus serves as the chief protective barrier against pathogenic and mechanical insults in respiratory, gastrointestinal, and urogenital tracts. Altered mucin expression, the major component of mucus, in conjunction with differential glycosylation has been strongly associated with both benign and malignant pathologies of colon. Mucins and their associated glycans arbitrate their impact sterically as well as mechanically by altering molecular and microbial spectrum during pathogenesis. Mucin expression in normal and pathological conditions is regulated by nonspecific (dietary factors and gut microbiota) and specific (epigenetic and transcriptional) modulators. Further, recent studies highlight the impact of altering mucin glycome (cancer-associated carbohydrate antigens including …

Molecular Implications Of Muc5ac-Cd44 Axis In Colorectal Cancer Progression And Chemoresistance, Ramesh Pothuraju, Satyanarayana Rachagani, Shiv Ram Krishn, Sanjib Chaudhary, Rama Krishna Nimmakayala, Jawed A. Siddiqui, Koelina Ganguly, Imayavaramban Lakshmanan, Jesse L. Cox, Kavita Mallya, Sukhwinder Kaur, Surinder K. Batra

Journal Articles: Biochemistry & Molecular Biology

BACKGROUND: Differential expression of mucins has been associated with several cancers including colorectal cancer (CRC). In normal physiological conditions, secretory mucin MUC5AC is not expressed in the colonic mucosa, whereas its aberrant expression is observed during development of colon cancer and its precursor lesions. To date, the molecular mechanism of MUC5AC in CRC progression and drug resistance remains obscure.

METHODS: MUC5AC expression was determined in colon tissue microarray by immunohistochemistry. A RNA interference and CRISPR/Cas9-mediated system was used to knockdown/knockout the MUC5AC in CRC cell lines to delineate its role in CRC tumorigenesis using in vitro functional assays and in …

Distribution Of Human Exposure To Ozone During Commuting Hours In Connecticut Using The Cellular Device Network, Owais Gilani, Simon Urbanek, Michael J. Kane

Faculty Journal Articles

Epidemiologic studies have established associations between various air pollutants and adverse health outcomes for adults and children. Due to high costs of monitoring air pollutant concentrations for subjects enrolled in a study, statisticians predict exposure concentrations from spatial models that are developed using concentrations monitored at a few sites. In the absence of detailed information on when and where subjects move during the study window, researchers typically assume that the subjects spend their entire day at home, school, or work. This assumption can potentially lead to large exposure assignment bias. In this study, we aim to determine the distribution of …

Chulalongkorn University Theses and Dissertations (Chula ETD)

Platynosomum fastosum is a cat liver fluke causing hepatobiliary diseases in cats. To evaluate the criterior to support the suspicion index for early disease detection during subclinical infection, the biochemical parameters composed of liver, pancreatic enzymes, tumor markers were evaluated in 14 P. fastosum naturally-infected cats. As a result, alanine transaminase (ALT) and gamma glutamyl transferase (GGT) were found elevated in 57.8% (8/14) of infected cats. For the diagnostic imaging, bile sediments were present in 85.7% (12/14) of infected cats in their gallbladders. Since the number of bile-derived P. fastosum eggs were significantly higher than that from fecal samples (p=0.001), …
