Objective: Sepsis is a major public health problem. Understanding the epidemiology of sepsis subtypes is important to quantify the magnitude of the problem and identify targets for system wide treatment strategies. We sought to describe the current national epidemiology of community-acquired (CAS), hospital-acquired (HAS) and healthcare-associated sepsis (HCAS) hospitalizations among academic medical centers in the United States using current discharge diagnosis taxonomies.

Methods: Retrospective analysis of patient discharge data from the Vizient Clinical Data Base/Resource Manager. We identified sepsis hospitalizations using four ICD-10 coding strategies: (1) "Martin" sepsis codes (21 ICD-10 codes), (2) "Angus" sepsis codes (ICD-10 infection + ICD-10 …

Informal And Incidental Learning In The Clinical Learning Environment: Learning Through Complexity And Uncertainty During Covid-19, Dimitrios Papanagnou, Karen E Watkins, Henriette Lundgren, Grace A Alcid, Deborah Ziring, Victoria J Marsick

Department of Emergency Medicine Faculty Papers

In the time of the COVID-19 pandemic, where clinical environments are plagued by both uncertainty and complexity, the importance of the informal and social aspects of learning among health care teams cannot be exaggerated. While there have been attempts to better understand the nuances of informal learning in the clinical environment through descriptions of the tacit or hidden curriculum, incidental learning in medical education has only been partially captured in the research. Understood through concepts borrowed from the Cynefin conceptual framework for sensemaking, the early stages of the pandemic immersed clinical teams in complex and chaotic situations where there was …

Carboxylesterase 1d (Ces1d) is a crucial enzyme with a wide range of activities in multiple tissues. It has been reported to localize predominantly in ER. Here, we found that Ces1d levels are significantly increased in obese patients with type 2 diabetes. Intriguingly, a high level of Ces1d translocates onto lipid droplets where it digests the lipids to produce a unique set of fatty acids. We further revealed that adipose tissue-specific Ces1d knock-out (FKO) mice gained more body weight with increased fat mass during a high fat-diet challenge. The FKO mice exhibited impaired glucose and lipid metabolism and developed exacerbated liver …

Treatment Disparities In Emergency Medical Services: The Influence Of Race/Ethnicity, Obesity, And English Proficiency, Jamie Kennel

Dissertations and Theses

Different treatment in healthcare settings provided to different social groups of people may lead to disparities in health, quality of life, and life span. Despite the critical role among healthcare services that Emergency Medical Services (EMS) provides disproportionately for marginalized communities, it remains unclear if and to what extent treatment disparities take place in the pre-hospital setting. Guided by the theoretical frameworks of social worth, aversive racism, and stigma, this study utilizes medical chart data from three different public and private datasets to investigate treatment disparities by Emergency Medical Service providers for racial minority, obese, and limited English proficiency patients. …

Macrophage Migration Inhibitory Factor (Mif) Makes Complex Contributions To Pain-Related Hyperactivity Of Nociceptors After Spinal Cord Injury, Alexis Bavencoffe, Emily A Spence, Michael Y Zhu, Anibal Garza-Carbajal, Kerry E Chu, Ona E Bloom, Carmen W Dessauer, Edgar T Walters

Faculty, Staff and Student Publications

Neuropathic pain is a major, inadequately treated challenge for people with spinal cord injury (SCI). While SCI pain mechanisms are often assumed to be in the CNS, rodent studies have revealed mechanistic contributions from primary nociceptors. These neurons become chronically hyperexcitable after SCI, generating ongoing electrical activity that promotes ongoing pain. A major question is whether extrinsic chemical signals help to drive ongoing electrical activity after SCI. People living with SCI exhibit acute and chronic elevation of circulating levels of macrophage migration inhibitory factor (MIF), a cytokine implicated in preclinical pain models. Probable nociceptors isolated from male rats and exposed …

Modified Jaw Thrust I-Gel Insertion Technique In Adults: A Case Series, Dileep Kumar

Department of Anaesthesia

Background: The I-gel is a second-generation supraglottic airway device that is built with a noninflatable elliptical gel material cuff and has a wide semirigid stem. The I-gel supralaryngeal seal has shown promising efficacy for both spontaneous and controlled ventilation under general anesthesia. The recommended, standard I-gel insertion technique is relatively challenging due to its shape and cuff size. Usually, the I-gel becomes entrapped at the oral cavity and requires excessive force to negotiate across the oropharynx, resulting in insertion resistance, tongue obstruction, insertion failure, and intraoral trauma. This case series evaluated a modified jaw thrust I-gel insertion technique because it …
