BACKGROUND AND AIMS: Sepsis is a complex rapidly progressive infectious disease that remain a major cause of morbidity and mortality in surgical patients and trauma victims. Edaravone a novel free radical scavenger was approved in 2001 in Japan for treatment of acute cerebral and myocardial infarction. Hence, in this work we attempt to evaluate its role in cases of septic peritonitis (SP). MATERIAL AND METHODS: This is a prospective randomized observer-blinded study carried out in surgical Intensive Care Unit (ICU) after approval by Hospital Ethical Committee...

OBJECTIVES: Septic cardiomyopathy is a well-described consequence of septic shock and is associated with increased sepsis-related mortality. The myocardial performance index (MPI), a parameter derived from echocardiographic tissue Doppler measurements, allows for a more sensitive assessment of global cardiac function than do traditional metrics for cardiac function. The authors hypothesized that changes in left ventricular MPI in patients with severe sepsis would be associated with a higher 90-day mortality...

BACKGROUND: With increasing public reporting of outcomes and bundled payments, hospitals and providers are scrutinized for morbidity and mortality. The impact of patient transfer before colorectal surgery has not been well characterized in a risk-adjusted fashion. OBJECTIVE: We hypothesized that hospital-to-hospital transfer would independently predict morbidity and mortality beyond traditional predictor variables. DESIGN: We constructed a retrospective cohort of 158,446 patients who underwent colorectal surgery using the 2009-2013 American College of Surgeons National Surgical Quality Improvement Program database...

BACKGROUND: Despite extensive research regarding risk factors for adverse events after total joint arthroplasty (TJA), there are few publications describing the timing at which such adverse events occur. QUESTIONS/PURPOSES: (1) On which postoperative day do certain adverse events occur? (2) What adverse events occur earlier after TKA than after THA? (3) For each adverse event, what proportion occurred after hospital discharge? METHODS: We screened the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) to identify all patients undergoing primary THA and primary TKA between 2005 and 2013, resulting in a study population of 124,657 patients evaluated as part of this retrospective database analysis...

Importance: The Second Universal Definition of Myocardial Infarction (MI) divides MIs into different types. Type 1 MIs result spontaneously from instability of atherosclerotic plaque, whereas type 2 MIs occur in the setting of a mismatch between oxygen demand and supply, as with severe hypotension. Type 2 MIs are uncommon in the general population, but their frequency in human immunodeficiency virus (HIV)-infected individuals is unknown. Objectives: To characterize MIs, including type; identify causes of type 2 MIs; and compare demographic and clinical characteristics among HIV-infected individuals with type 1 vs type 2 MIs...

BACKGROUND: The U.S. medical malpractice system assumes that the threat of liability should deter negligence but it is unclear whether malpractice environment impacts healthcare quality. We thus sought to explore the association between state malpractice environment and post-operative complication rates. STUDY DESIGN: This observational study included Medicare fee-for-service beneficiaries undergoing one of the following surgeries in 2010: colorectal, lung, esophageal, or pancreatic resection, total knee arthroplasty, craniotomy, gastric bypass, abdominal aortic aneurysm repair, coronary artery bypass grafting, or cystectomy...

INTRODUCTION: Troponins are known to be released in response to cardiac damage and therefore are the biomarkers of choice for the early diagnosis of acute myocardial infarction (AMI), improving outcome in patients presenting with chest pain. However, false results can occur due to interference from other substances in the blood. CASE: A 52-year-old male with a past medical history of alcohol abuse, hypertension, and coronary artery bypass graft at age 34 with normal stress test 2 years before presented to the emergency department (ED) complaining of 1 day of non-exertional chest pain with radiation to the neck and left arm...

Adrenergic receptors couple to Gs-proteins leading to transmembrane adenylyl cyclase activation and cytosolic cyclic adenosine monophosphate (cAMP) production. Cyclic AMP is also produced in the mitochondrial matrix, where it regulates respiration through protein kinase A (PKA)-dependent phosphorylation of respiratory chain complexes. We hypothesized that a blunted mitochondrial cAMP-PKA pathway would participate in sepsis-induced heart dysfunction. Adult male mice were subjected to intra-abdominal sepsis. Mitochondrial respiration of cardiac fibers and myocardial contractile performance were evaluated in response to 8Br-cAMP, PKA inhibition (H89), soluble adenylyl cyclase inhibition (KH7), and phosphodiesterase inhibition (IBMX; BAY60-7550)...

Sepsis is an exaggerated systemic inflammatory response to persistent bacteria infection with high morbidity and mortality rate clinically. β-arrestin 2 modulates cell survival and cell death in different systems. However, the effect of β-arrestin 2 on sepsis-induced cardiac dysfunction is not yet known. Here, we show that β-arrestin 2 overexpression significantly enhances animal survival following cecal ligation and puncture (CLP)-induced sepsis. Importantly, overexpression of β-arrestin 2 in mice prevents CLP-induced cardiac dysfunction...

Vasopressor and inotropes are beneficial in shock states. Norepinephrine is considered the first-line vasopressor for patients with sepsis-associated hypotension. Dobutamine is considered the first-line inotrope in sepsis, and should be considered for patients with evidence of myocardial dysfunction or ongoing signs of hypoperfusion. Vasopressor and inotrope therapy has complex effects that are often difficult to predict; emergency providers should consider the physiology and clinical trial data. It is essential to continually reevaluate the patient to determine if the selected treatment is having the intended result...

Cardiac dysfunction caused by the impairment of myocardial contractility has been recognized as an important factor contributing to the high mortality in sepsis. Calpain activation in the heart takes place in response to increased intracellular calcium influx resulting in proteolysis of structural and contractile proteins with subsequent myocardial dysfunction. The purpose of the present study was to test the hypothesis that increased levels of calpain in the septic heart leads to disruption of structural and contractile proteins and that administration of calpain inhibitor-1 (N-acetyl-leucinyl-leucinyl-norleucinal (ALLN)) after sepsis induced by cecal ligation and puncture prevents cardiac protein degradation...

INTRODUCTION: Little is known about the time-course changes in left ventricular myocardial deformation in patients with Takotsubo cardiomyopathy (TC) using layer-specific quantification of myocardial deformation assessed by 2-dimensional speckle tracking echocardiography (2DSTE). CASE SUMMARY: In this retrospective 2DSTE follow-up study of 3 female patients with sepsis-induced TC, we examined changes in strain among the 3 myocardial layers, and examined the changes in left ventricular diastolic function and right ventricular systolic function...

BACKGROUND: This study examines the clinical utility of plasma neutrophil gelatinase-associated lipocalin (NGAL) as an indicator of myocardial dysfunction and mortality in severe sepsis and septic shock. METHODS: We designed a prospective cohort study in an intensive care unit, and 53 patients with severe sepsis or septic shock were included. Data were used to determine a relationship between NGAL and the development of myocardial dysfunction and mortality. These associations were determined by the Mann-Whitney test, multiple logistic regression, plotting the receiver operating characteristic (ROC) curve, Kaplan-Meier curves and Spearman test...
