Decreasing Time To Broad Spectrum Antibiotics For Septic Patients In The Emergency Department, Joseph J. Zieminski, Emily E. Bryant

Journal of Patient-Centered Research and Reviews

Background: Timely administration of broad spectrum antibiotics has been shown to be directly correlated with decreased mortality for patients with severe sepsis and septic shock. As such, both the Surviving Sepsis Campaign and the SEP-1 CMS measure recognize timely antibiotic administration as a cornerstone of therapy for patients with severe sepsis or septic shock.

Purpose: Decrease time to broad spectrum antibiotic administration for septic patients in the emergency department (ED) of Aurora St. Luke’s Medical Center.

Methods: An alert within the electronic medical record was created to more rapidly identify potentially septic patients in the ED. After receiving the alert, …

Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts

Williams Honors College, Honors Research Projects

Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.

Objectives: To evaluate the use of biomarkers in children seen in the Emergency …

Mc-Ppea As A New And More Potent Inhibitor Of Clp-Induced Sepsis And Pulmonary Inflammation Than Fk866., Peixin Huang, Mark W Lee, Keivan Sadrerafi, Daniel P. Heruth, Li Q. Zhang, Dev Maulik, Shui Qing Ye

Manuscripts, Articles, Book Chapters and Other Papers

Our previous study indicated that overexpression of nicotinamide phosphoribosyltransferase (NAMPT) aggravated acute lung injury, while knockdown of NAMPT expression attenuated ventilator-induced lung injury. Recently, we found that meta-carborane-butyl-3-(3-pyridinyl)-2E-propenamide (MC-PPEA, MC4), in which the benzoylpiperidine moiety of FK866 has been replaced by a carborane, displayed a 100-fold increase in NAMPT inhibition over FK866. Here, we determined the effects of MC4 and FK866 on cecal ligation and puncture (CLP) surgery-induced sepsis in C57BL/6J mice. MC4 showed stronger inhibitory effects than FK866 on CLP-induced mortality, serum tumor necrosis factor α (TNFα) levels, pulmonary myeloperoxidase activity, alveolar injury, and interleukin 6 and interleukin1β messenger …

Endothelial Hspa12b Is A Novel Protein For The Preservation Of Cardiovascular Function In Polymicrobial Sepsis Via Exosome Mir-126, Xia Zhang

Electronic Theses and Dissertations

Sepsis is the most frequent cause of mortality in most intensive care units. Cardiovascular dysfunction is a major complication associated with sepsis, with high mortality rates up to 70%. Currently, there is no effective treatment approach for sepsis.

The integrity of the endothelium is fundamental for the homeostasis of the cardiovascular system. Sepsis induces endothelial cell injury which is the key factor for multiple organ failure. The increased expression of adhesion molecules and chemokines in endothelial cell promotes leukocytes infiltration into the tissue. The loss of tight junction proteins and increased permeability of the endothelial cells will provoke tissue hypoxia …

Gram-Negative Bacteria And Sepsis, Christine D. Ridge

Nursing Student Class Projects (Formerly MSN)

Today’s medical world encompasses an environment in which gram-negative bacteria that once were defeated with common antibiotics, have now become resistant. Gram-negative bacteria like Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter, and Acinetobacter are pathogens that are an emerging threat causing sepsis due to multidrug-resistance (Pop-Vicas & Opal, 2014, p.189). The multidrug-resistance mechanisms of gram-negative bacteria coupled with a patient population commonly seen in hospital settings, that consist of immunocompromised adults due to advancing age, comorbidities (e.g. AIDS, history of transplants, diabetes, and chemotherapy), and immunotherapies, create an environment for advanced infection or sepsis to take place.

Complications of multidrug-resistant gram-negative bacteria …

Hydrocortisone, Vitamin C And Thiamine For The Treatment Of Severe Sepsis And Septic Shock: A Retrospective Before-After Study, Paul E. Marik, Vikramjit Khangoora, Racquel Rivera, Michael H. Hooper, John Catravas

Bioelectrics Publications

BACKGROUND: The global burden of sepsis is estimated as 15 to 19 million cases annually with a mortality rate approaching 60% in low income countries.

METHODS: In this retrospective before-after clinical study, we compared the outcome and clinical course of consecutive septic patients treated with intravenous vitamin C, hydrocortisone and thiamine during a 7-month period (treatment group) compared to a control group treated in our ICU during the preceding 7 months. The primary outcome was hospital survival. A propensity score was generated to adjust the primary outcome.

FINDINGS: There were 47 patients in both treatment and control groups with no …

Robust System For Infection Control: An Industrial Systems Engineering Approach, Sundaravel Vinay Swarup Achudhan

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Health care delivery in the United States needs improvement. Each year about 98,000 people die as a result of medical errors and the United States is outranked by a number of developed countries in life expectancy, mortality and comorbidity. Healthcare quality is determined based on the quality of the service provided to the patient during their visit. Apart from the traditional problem solving design and development tools used to improve healthcare quality, The National Academy of Engineering and the Institute of Medicine recommend systems engineering principle and systems engineering tools to be used in health care to improve the industry. …

Inflammatory Proteins, Genetic Variation, And Environmental Influences On Health Care Associated Infection Development In Sepsis, Reba Antoinette Umberger

Theses and Dissertations (ETD)

The purpose of this study was to determine the impact of baseline systemic inflammation (pro‑inflammatory cytokine, anti‑inflammatory cytokine, and their ratio), genetic variability, and environment on the development of health care associated infections (HAI) among sepsis patients during their ICU stay (up to 28 days).

Methods: A prospective observation study was conducted at the Veterans Affairs Medical Center in the Medical Intensive Care Unit over an 18 month period. A total of 78 patients were enrolled within 72 hours of presenting to the ICU with sepsis. Patient were excluded if they were receiving immunosuppressants (chemotherapy or greater than one mg/kg …
