We present a comparison between three left ventricular assist devices (LVADs): HeartWare (HVAD) (HeartWare International Inc., Framingham, MA, USA), HeartMate II (HMII) and HeartMate III (HMIII) (Thoratec Corp., Pleasanton, CA, USA). To our knowledge, no study to date has aimed at placing these three devices in juxtaposition. Between June 2007 and June 2017, 108 consecutive patients received HMII, n = 77 (71.3%), HVAD, n = 14 (13%), or HM III, n = 17 (15.7%), for end-stage heart failure. Mean age was 63...

BACKGROUND AND OBJECTIVES: AKI in the hospital is common and is associated with excess mortality. We examined whether AKI is also independently associated with a higher risk of different cardiovascular events in the first year after discharge. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a retrospective analysis of a cohort between 2006 and 2013 with follow-up through 2014, within Kaiser Permanente Northern California. We identified all adults admitted to 21 hospitals who had one or more in-hospital serum creatinine test result and survived to discharge...

Microvascular endothelial cells play a pivotal role in the pathogenesis of sepsis-induced inflammatory responses and multiple organ failure. Therefore, they represent an important target for pharmacological intervention in the treatment of sepsis. Glucocorticosteroids were widely used in the treatment of sepsis but vast evidence to support their systemic use is lacking. The limited effects of glucocorticoids in the treatment of sepsis may be explained by differential effects of drug initiated NF-κB inhibition in different cell types and insufficient drug delivery in target cells...

Early and adequate restoration of endothelial and tubular renal function is a substantial step during regeneration after ischemia reperfusion (IR) injury, occurring, e.g., in kidney transplantation, renal surgery, and sepsis. While tubular epithelial cell injury has long been of central importance, recent perception includes the renal vascular endothelium. In this regard, the fibrin cleavage product fibrinopeptide Bβ15-42 mitigate IR injury by stabilizing interendothelial junctions through its affinity to VE-cadherin...

Sepsis, in essence, is a serious clinical condition that can subsequently result in death as a consequence of a systemic inflammatory response syndrome including febrile leukopenia, hypotension, and multiple organ failures. To date, such life-threatening organ dysfunction remains one of the leading causes of death in intensive care units, with an increasing incidence rate worldwide and particularly within the rapidly growing senior population. While most of the clinical trials are aimed at dampening the overwhelming immune response to infection that spreads through the bloodstream, based on several human immunological investigations, it is now widely accepted that susceptibility to nosocomial infections and long-term sepsis mortality involves an immunosuppressive phase that is characterized by a decrease in some subsets of dendritic cells (DCs)...

BACKGROUND: Dialysis-requiring acute kidney injury (D-AKI) is a serious complication in hospitalized heart failure (HF) patients. However, data on national trends are lacking after 2002. METHODS: We used the Nationwide Inpatient Sample (2002-2013) to identify HF hospitalizations with and without D-AKI. We analyzed trends in incidence, in-hospital mortality, length of stay (LoS) and cost. We calculated adjusted odds ratios (aOR) for predictors of D-AKI and for outcomes including in-hospital mortality and adverse discharge (discharge to skilled nursing facilities, nursing homes, etc)...

BACKGROUND: Patients undergoing percutaneous mechanical circulatory support (pMCS)-assisted percutaneous coronary intervention (PCI) represent a high-risk group vulnerable to complications and readmissions. HYPOTHESIS: Thirty-day readmissions after pMCS-assisted PCI are common among patients with comorbidities and account for a significant amount of healthcare spending. METHODS: Patients undergoing PCI and pMCS (Impella, TandemHeart, or intra-aortic balloon pump) for any indication between January 1, 2012, and November 30, 2014, were selected from the Nationwide Readmissions Database...

Sepsis is a dysregulated immune response to an infection that leads to organ dysfunction. Knowledge of the pathophysiology of organ failure in sepsis is crucial for optimizing the management and treatment of patients and for the development of potential new therapies. In clinical practice, six major organ systems - the cardiovascular (including the microcirculation), respiratory, renal, neurological, haematological and hepatic systems - can be assessed and monitored, whereas others, such as the gut, are less accessible...

Critically ill geriatric patients are vitally endangered due to the aging processes of organs, the frequently existing multimorbidity with subsequent polypharmacy and the typical geriatric syndrome of functional impairments. Aging processes in organs lower the clinical threshold for organ dysfunction and organ failure. Physiological organ aging processes with practical consequences for intensive care medicine are atypical manifestion of sepsis in immunosenescence, altered pharmacokinetics, reduced tolerance to hypovolemia due to proportionally reduced water compartment of the body in old age, the frequently only apparently normal function of the kidneys and the continuous reduction in pulmonary function in old age...

OBJECTIVE:  High-density lipoprotein (HDL) has been epidemiologically shown to be associated with the outcome of sepsis. One potential mechanism is that HDL possesses pleiotropic effects, such as anti-apoptosis, some of which can be ascribed to sphingosine 1-phosphate (S1P) carried on HDL via apolipoprotein M (apoM). Therefore, the aim of this study was to elucidate the roles of apoM/S1P in the consequent lethal conditions of sepsis, such as multiple organ failure caused by severe inflammation and/or disseminated intravascular coagulation...

BACKGROUND: The most common multiple-organ transplant is the simultaneous pancreas-kidney transplantation (SPK). It is usually offered to patients who have insulin-dependent diabetes mellitus and those with diabetic nephropathy and renal failure that has already been established. In this study we present the results of 15 years of SPK in a transplant hospital center in Paraná, Brazil, and evaluated survival, immunosuppression, and transplant-related problems. METHODS: This study was a retrospective analysis of 131 SPK transplants performed at the Angelina Caron Hospital between January 2001 and December 2015...

Severe sepsis is critical to health and can result in acute renal failure (ARF). Tissue factor (TF) and thrombomodulin (TM) play key roles in vascular endothelial functions by helping maintain microcirculation in the kidney. Budding uninhibited by benzimidazole-1 (Bub1) plays a role in Akt and JNK signaling, which control TF and TM, respectively. We hypothesized that Bub1 could control vascular endothelial function in sepsis. The aim of this study was to determine the role of Bub1 in septic ARF. We used Mouse cecum ligation and puncture (CLP) using low Bub1 expressing (Bub1) and wild-type (Bub1) mice in vivo and lipopolysaccharide (LPS) stimulation of human aortic endothelial cell (HAEC) in vitro...

Microvascular dysfunction leads to multi-organ failure and mortality in sepsis. Our previous studies demonstrated that administration of exogenous endothelial progenitor cells (EPCs) confers protection in sepsis as evidenced by reduced vascular leakage, improved organ function, and increased survival. We hypothesize that EPCs protect the microvasculature through the exosomes-mediated transfer of microRNAs (miRNAs). Mice were rendered septic by cecal ligation and puncture (CLP), and EPC exosomes were administered intravenously at 4 hr after CLP...

Sepsis is a systemic inflammatory response as a result of uncontrolled infections. Neutrophils are the first cells to reach the primary sites of infection and chemokines play a key role in recruiting neutrophils. However, in sepsis chemokines could also contribute to neutrophil infiltration to vital organs leading to multiple organ failure. ACKR2 is an atypical chemokine receptor, which can remove and degrade inflammatory CC chemokines. The role of ACK2 in sepsis is unknown. Using a model of cecal ligation and puncture (CLP), we demonstrate here that ACKR2 deficient () mice exhibited a significant reduction in the survival rate compared to similarly treated wild type (WT) mice...

Patients who underwent orthotopic liver transplantation (OLT) frequently develop chronic kidney disease, with those who present postoperative acute kidney failure and require renal replacement therapy (RRT) at higher risk. The objective of the study was to assess the kidney function and long-term survival of patients who underwent OLT and required RRT during or in the immediate postoperative period. Medical records of OLT and postoperative RRT patients with over 6-month survival were reviewed between January 1, 2005, and December 31, 2015...
