To investigate the miRNA-21 over-expression in the acute kidney injury induced by sepsis, we developed a sepsis induced in vitro model by lip polysaccharide (LPS) and in vovo model by cecal ligation and puncture (CLP) surgery. LPS or CLP surgery induced kidney cell apoptosis increasing. However, the kidney injury indexes of miRNA groups which were transfected with miRNA-21 were significantly suppressed. In further study, the relative proteins expressions were evaluated to explain the miRNA-21 mechanism to improve sepsis induced kidney cell apoptosis...

Although favorable immune responses to low-dose irradiation (LDI) have been observed in normal mice, i.e., a hormesis effect, little is known about the effects of LDI in infectious diseases. In this study, we examined the effects of LDI on mice with sepsis, a severe and often lethal hyperinflammatory response to bacteria. Female C57BL/6 mice were whole-body irradiated with 10cGy 48h before Escherichia coli infection, and survival, bacterial clearance, cytokines, and antioxidants were quantified. LDI pretreatment significantly increased survival from 46...

BACKGROUND: Patients with upper third esophageal cancer or esophageal cancer with upper mediastinal paratracheal lymph node metastases are often precluded from surgery because of technical difficulties. With the aid of robotic surgery, an excellent overview and reach of the thoracic inlet can be accomplished. In this way, patients with upper mediastinal esophageal cancer are eligible for esophageal resection with curative intent. The aim of this study was to review the results of a consecutive series of patients who underwent robot-assisted minimally invasive esophagectomy (RAMIE) for tumors of the upper 1/3 of the esophagus or positive lymph nodes in the upper mediastinum...

A 66-year-old woman presented to the Emergency Department with a florid sepsis-like picture, a two-week history of fever, relative hypotension with end organ ischemia (unexplained liver enzyme and troponin elevations), and nonspecific constitutional symptoms. She was initially found to have a urinary tract infection but, despite appropriate treatment, her fever persisted and her white blood cell count continued to rise. During her hospitalization the patient manifested leukocytosis to 47,000 WBC/μL, ESR 67 mm/hr (normal range 0-42 mm/hr), CRP 17...

The translocation of bacteria across the intestinal epithelium of immunocompromised patients can lead to bacteremia and life-threatening sepsis. Extraintestinal Pathogenic Escherichia coli (ExPEC), so named because this pathotype infects tissues distal to the intestinal tract, is a frequent cause of such infections, is often multidrug resistant, and chronically colonizes a sizable portion of the healthy population. Although several virulence factors and their roles in pathogenesis are well described for ExPEC that cause urinary tract infections and meningitis, they have not been linked to translocation through intestinal barriers, a fundamentally distant yet important clinical phenomenon...

During sepsis, the alarmin HMGB1 is released from tissues and promotes systemic inflammation that results in multi-organ damage, with the kidney particularly susceptible to injury. The severity of inflammation and pro-damage signaling mediated by HMGB1 appears to be dependent on the alarmin's redox state. Therefore, we examined HMGB1 redox in kidney cells during sepsis. Using intravital microscopy, CellROX labeling of kidneys in live mice indicated increased ROS generation in the kidney perivascular endothelium and tubules during lipopolysaccharide (LPS)-induced sepsis...

BACKGROUND: Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality...

This study tested the hypothesis that combined therapy with exendin-4 (Ex4) and autologous adipose-derived mesenchymal stem cells (ADMSCs) was superior to either alone for protecting renal function against acute kidney ischemia-reperfusion (IR; 40-min ischemia/27-h reperfusion) injury when complicated by sepsis syndrome (SS; by cecal-ligation-puncture). Adult-male Sprague-Dawley rats (n=40) were equally divided into group 1 (sham-control), group 2 (IR-SS), group 3 (IR-SS + Ex4, 10 μg/kg subcutaneously 30 min after reperfusion and daily for 3 days), group 4 [IR-SS + ADMSC (1...

INTRODUCTION: Sepsis increases the long-term incidence of ischemic stroke (IS). The chances for long-term IS in patients who are discharged after sepsis are unclear. Our aim was to demonstrate long-term risk chances of IS after septicemia discharge. We used a nomogram to identify those septicemia survivors with the higher risk of developing IS. METHODS: Inpatient data were used from the Taiwan Longitudinal Health Insurance Database, from 2001 to 2003. The event was IS rehospitalization after discharge of septicemia...

Acute kidney injury (AKI) is a common syndrome with increased mortality, a heavy burden of illness and high cost. The Kidney Disease Improving Global Outcomes (KDIGO) criteria for staging of AKI have been validated in large patient cohorts and classify AKI into three stages. In order to achieve prevention or early therapy, the focus of scientific interest is early detection and risk prediction of AKI. The combination of the two cell cycle arrest markers [TIMP-2]·[IGFBP7] in the urine shows good results in the risk prediction of AKI in different clinical settings (intensive care medicine, sepsis, cardiac surgery, emergency department)...

BACKGROUND: Acute Kidney Injury (AKI) has a significant mortality rate. In developing countries, mortality due to AKI is high due to lack of access to dialysis facilities and related cost. The main goal of International Society of Nephrology (ISN) 0 by 25 initiative is to eliminate deaths due to AKI. Peritoneal dialysis is an underutilized modality in such a scenario. The aim of this study was to look into effectiveness of starting Acute stylet Peritoneal Dialysis (PD) in a resource constraint settings...

OBJECTIVES: Apelin-13 was recently proposed as an alternative to the recommended β-adrenergic drugs for supporting endotoxin-induced myocardial dysfunction. Since Apelin-13 signals through its receptor (Apelin peptide jejunum) to exert singular inotropic/vasotropic actions and to optimize body fluid balance, this candidate pathway might benefit septic shock management. Whether the newly discovered ELABELA (ELA), a second endogenous ligand of the Apelin peptide jejunum receptor highly expressed in the kidney, further improves cardio-renal impairment remains unknown...

OBJECTIVE: Cardiac arrest following neurosurgery is a devastating complication associated with significant postoperative morbidity and mortality. There are no published studies that have used a large and robust multicenter database to specifically examine demographic and surgical risk factors associated with cardiac arrests following craniotomy and spine surgeries, respectively. PATIENTS AND METHODS: We retrospectively analyzed data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for the period between January 1, 2007 and December 31, 2013, focusing on cardiac arrest associated with craniotomy and spine surgery from the intraoperative period to 30days after surgery...

J Prakash, V C Ganiger
The incidence of acute kidney injury in pregnancy (P-AKI) has declined significantly over the last three decades in developing countries. However, it is still associated with significant fetomaternal mortality and morbidity. The diagnosis of P-AKI is based on the serum creatinine increase. The usual formulas for estimating glomerular filtration rate (GFR) are not validated in this population. The incidence of P-AKI with respect to total AKI cases has decreased in the last three decades from 25% in 1980s to 9% in 2000s at our centre...

Our study evaluated the differences between early and late hemodialysis (HD) initiation in the intensive care unit (ICU) according to the RIFLE (Risk, Injury, Failure, Loss, and End-stage renal failure) and AKIN (Acute Kidney Injury Network) classifications. On the assumption that early initiation of HD in critical patients according to the RIFLE and AKIN criteria decreases mortality, we retrospectively evaluated the medical records of 68 patients in our medical ICU and divided the patients into 2 groups: Those undergoing HD in no risk, risk, or injury stage according to RIFLE and in stage 0, I, or II according to AKIN were defined as early HD and those in failure stage according to RIFLE and in stage III according to AKIN were defined as late HD...

Sepsis still remains a challenging healthcare problem with high mortality rate. To improve outcome, early diagnosis and monitoring of sepsis is of utmost importance. In this process objective laboratory parameters are the most helpful. Procalcitonin and C-reactive protein are the most commonly used and recommended markers of sepsis however, more than 200 sepsis biomarkers have already been published. This mini review focuses on nonconventional novel possibilities for the recognition of sepsis severity. Presepsin, actin and actin scavenger proteins (gelsolin and Gc-globulin) and orosomucoid are discussed...

Post-ischemic neurodegeneration remains the principal cause of mortality following cardiac resuscitation. Recent studies have implicated gastrointestinal ischemia in the sepsis-like response associated with the post-cardiac arrest syndrome (PCAS). However, the extent to which the resulting low-grade endotoxemia present in up to 86% of resuscitated patients affects cerebral ischemia-reperfusion injury has not been investigated. Here we report that a single injection of low-dose lipopolysaccharide (50μg/kg, IP) delivered after global cerebral ischemia (GCI) induces blood-brain barrier permeability, microglial activation, cortical injury, and functional decline in vivo, compared to ischemia alone...
