RATIONALE: Improving the prospective identification of patients with the systemic inflammatory response syndrome (SIRS) and sepsis at low for organ dysfunction and death is a major clinical challenge. OBJECTIVE: To develop and validate a multi-biomarker based prediction model for 28-day mortality in critically ill patients with SIRS and sepsis. METHODS: The derivation cohort (n=888) and internal test cohort (n=278) were from a prospective study of critically ill intensive care unit (ICU) patients meeting 2 of 4 SIRS criteria at an academic medical center for whom plasma was obtained within 24 hours...

Cystinosis is a rare autosomal recessive lysosomal storage disease characterized by multi-organ cystine accumulation, leading to renal failure and extra-renal organ dysfunction. Azoospermia of unknown origin is the main cause of infertility in all male cystinosis patients. Although spermatogenesis has shown to be intact at the testicular level in some patients, no male cystinosis patient has been reported yet to have successfully induced conception.We present the first successful conception ever reported, induced by a 27-year-old male renal transplant infantile nephropathic cystinosis patient through percutaneous epididymal sperm aspiration (PESA) followed by intracytoplasmatic sperm injection (ICSI)...

BACKGROUND: Early detection of liver fibrosis in thalassemia patients and rapid initiation of treatment to interfere with its progression are extremely important. OBJECTIVE: This study aimed to find a sensitive, easy-to-detect and noninvasive method other than liver biopsy for early detection of liver fibrosis in thalassemia patients. METHODS: A total of 244 Chinese Thalassemia patients with non-transfusion-dependent thalassemia (NTDT, n = 105) or thalassemia major (TM, n = 139) and 120 healthy individuals were recruited into the present study, and blood collagen type IV (C IV), precollagen type III (PIIINPC) and hyaluronic acid (HA), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and ferritin were measured...

The adult cerebral inflammatory form of X-linked adrenoleukodystrophy is a rapidly progressive neurodegenerative disease, as devastating as childhood cerebral adrenoleukodystrophy. Allogeneic haematopoietic stem cell transplantation has been demonstrated to provide long-term neurological benefits for boys with the childhood cerebral form, but results in adults are sparse and inconclusive. We analysed data from 14 adult males with adult cerebral adrenoleukodystrophy treated with allogeneic haematopoietic stem cell transplantation on a compassionate basis in four European centres...

PURPOSE: We aim to determine whether hyperlactatemia, which suggests multi-organ dysfunction and impaired organic substrate metabolism, may predict intolerance to regional citrate anticoagulation (RCA) during continuous venovenous hemofiltration (CVVH). METHODS: We performed a single-center, retrospective observational study in critically ill patients with acute kidney injury or end-stage renal disease and evaluated the association of peak serum lactate levels with citrate intolerance (CI) during the initial 72 hours of RCA-CVVH, defined by serum total-to-ionized calcium >2...

The lung interfaces with atmospheric oxygen via a large surface area and is perfused by the entire venous return bearing waste products collected from the entire body. It is logical that the lung is endowed with generous anti-oxidative capacity derived both locally and from the circulation. The single-pass pleiotropic alpha-Klotho (αKlotho) protein was discovered when its genetic disruption led to premature multi-organ degeneration and early death. The extracellular domain of αKlotho is cleaved by secretases and released into circulation as endocrine soluble αKlotho protein and exerting wide-ranging cytoprotective effects including anti-oxidation on distant organs especially the lung, which exhibits high sensitivity to circulating αKlotho insufficiency...

A novel approach for the automatic chemiluminescence (CL) analysis of the complex samples is proposed. A multi-pumping flow system was successfully combined with fluidized reactor and direct-injection CL detector. The possibility of the approach was demonstrated on the determination of uric acid in saliva samples. Uric acid is clinically important analyte and its determination in biological fluids is related to human organism dysfunctions, such as gout. For the first time, the fast luminol - N-bromosuccinimide (NBS) reaction in an alkaline medium was used for the CL determination of uric acid in saliva samples...

BACKGROUND: From 1990-2005 at Ochsner Medical Center in New Orleans, LA, cardiopulmonary bypass (CPB) was used only when necessary during lung transplantation surgeries. Ochsner's lung transplant program was closed for more than 4 years after Hurricane Katrina, and since the program's reestablishment in 2010, the majority of lung transplantation surgeries have been performed with the patient on CPB and with a median sternotomy incision. The purpose of this study was to compare the outcomes of the CPB and non-CPB groups...

Rhabdomyolysis is a disorder characterized by acute damage of the sarcolemma of the skeletal muscle leading to release of potentially toxic muscle cell components into the circulation, most notably creatine phosphokinase (CK) and myoglobulin, and is frequently accompanied by myoglobinuria. In the present work, we evaluated the toxicity of p-phenylenediamine (PPD), a main component of hair dyes which is reported to induce rhabdomyolysis. We studied the metabolic effect of this compound in vivo with Wistar rats and in vitro with C2C12 muscle cells...

Acute kidney injury (AKI) is a clinical syndrome that complicates the course and worsens the outcome in a significant number of hospitalised patients. Recent advances in clinical and basic research will help with a more accurate definition of this syndrome and in the elucidation of its pathogenesis. With this knowledge we will be able to conduct more accurate epidemiologic studies in an effort to gain a better understanding of the impact of this syndrome. AKI is a syndrome that rarely has a sole and distinct pathophysiology...

With the ever-increasing use of carbon nanotubes (CNTs) in health-related and engineering applications, the hazardous risks of this material have become a major concern. It is well-known that CNTs accumulate with cytotoxic and genotoxic levels within vital organs. It has also been shown that treating cell cultures with CNTs resulted in cell cycle arrest and increased apoptosis/necrosis. The goal of this pilot study is to perform a comprehensive comparative study on the toxicity of single-wall (SW) and multi-wall (MW) carbon nanotubes in rat skin cells...

Microvascular dysfunction plays a key role in the pathology of sepsis, leading to multi-organ failure and death. Circulating endothelial progenitor cells (cEPCs) are critically involved in the maintenance of the vascular homeostasis in both physiological and pathological contexts. In this study, concentration of cEPCs in preterm infants with sepsis was determined to recognize whether the EPC mobilization would affect the clinical outcome of infantile sepsis. 133 preterm infants (81 with sepsis and 52 without sepsis) were enrolled in this study...

Extracorporeal liver support can be classified into cell-free, artificial methods (artificial liver support, ALS) and cell-based bioartificial methods (bioartificial liver support, BLS). ALS improves biochemical parameters of liver failure by the simultaneous removal of protein-bound and water-soluble substances. Here, the MARS therapy belongs to the most studied methods with a proved beneficial effect on hepatic encephalopathy (HE), hepatorenal syndrome (HRS) or hyperbilirubinemia. However, a general survival advantage of any liver support for liver failure has not been shown yet and is restricted to meta-analyses or patient subgroups...

Portomesenteric venous thrombosis (PMVT) is a rare but well-reported complication following laparoscopic surgery. We present three cases of PMVT following laparoscopic surgery. Our first case is a 71-year-old morbidly obese woman admitted for elective laparoscopic giant hiatus hernia (LGHH) repair. Post-operatively, she developed multi-organ dysfunction and computed tomography scan revealed portal venous gas and extensive small bowel infarct. The second patient is a 51-year-old man with known previous deep venous thrombosis who also had elective LGHH repair...

Hyperglycemia is a common feature of septic patients and has been associated with poor outcome and high mortality. In contrast, insulin has been shown to decrease mortality and to prevent the incidence of multi-organ failure but is often associated with deleterious hypoglycemia. Protein Tyrosine Phosphatase 1B (PTP1B) is a negative regulator of both insulin signaling and NO production, and has been shown to be an aggravating factor in septic shock. To evaluate the potential therapeutic effect of PTP1B blockade on glucose metabolism and insulin resistance in an experimental model of sepsis, we assessed the effect of PTP1B gene deletion in a cecal ligation and puncture (CLP) model of sepsis...

Transformation of circulating leukocytes from a dormant into an activated state with changing rheological properties leads to a major shift of their behavior in the microcirculation. Low levels of pseudopod formation or expression of adhesion molecules facilitate relatively free passage through microvessels while activated leukocytes with pseudopods and enhanced levels of adhesion membrane proteins become trapped in microvessels, attach to the endothelium and migrate into the tissue. The transformation of leukocytes into an activated state is seen in many diseases...

Birth asphyxia is a significant global health problem, responsible for ~1.2 million neonatal deaths each year worldwide. Those who survive often suffer from a range of health issues including brain damage-manifesting as cerebral palsy (CP)-respiratory insufficiency, cardiovascular collapse, and renal dysfunction, to name a few. Although the majority of research is directed toward reducing the brain injury that results from intrapartum birth asphyxia, the multi-organ injury observed in surviving neonates is of equal importance...

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating multi-systemic chronic illness of unknown etiology, classified as a neurological disorder by the World Health Organization (WHO). The symptomatology of the condition appears to emanate from a variety of sources of chronic neurological disturbance and associated distortions, and chronicity, in noxious sensory signaling and neuroimmune activation. This article incorporates a summary review and discussion of biomedical research considered relevant to this essential conception perspective...
