Monitoring of Intraperitoneal Fluid Volume during Peritoneal Equilibration Testing using Segmental Bioimpedance.

Background: Ultrafiltration failure and fluid overload are common in peritoneal dialysis (PD) patients. Knowledge of intraperitoneal volume (IPV) and time to peak IPV during a dwell would permit improved PD prescription. This study aimed to utilize trunk segmental bioimpedance analysis (SBIA) to quasi-continuously monitor IPV (IPVSBIA) during the peritoneal dwell.

Hadoop Oriented Smart Cities Architecture.

A smart city implies a consistent use of technology for the benefit of the community. As the city develops over time, components and subsystems such as smart grids, smart water management, smart traffic and transportation systems, smart waste management systems, smart security systems, or e-governance are added. These components ingest and generate a multitude of structured, semi-structured or unstructured data that may be processed using a variety of algorithms in batches, micro batches or in real-time.

Elevated serum total IgE alter the diagnostic performance of radio-immune assays for β-lactam specific antibody dosing.

Background: In vivo allergy tests and the detection of drug-specific antibodies are widely used in the diagnosis of β-lactam induced immediate-type hypersensitivity reactions. The diagnostic performance of immunoenzymatic tests for the demonstration of serum-specific IgE (IgEs) antibodies is influenced by total IgE values (IgEt). The aim of this study was to investigate whether the result obtained by radioimmunoassays (RIA) for β-lactams IgEs antibodies is correlated to IgEt.

Epidemiology of self-reported drug-induced immediate-type hypersensitivity reactions in the surgical population: a 5-year single-center survey in a romanian allergo-anaesthesia center.

Aim: Immediate-type hypersensitivity drug reactions are frequently under-reported, epidemiological data being imprecise. The aim of our study was to identify the drugs involved and to describe the clinical characteristics of previous immediate-type hypersensitivity reactions in a large series of Romanian surgical patients, and to establish the concordance between in vivo and in vitro tests.

Methods: Of the 807 surgical patients referred to our outpatient department of allergo-anaesthesia, we retrospectively enrolled 632 patients with previous drug-induced hypersensitivity reactions.

Effects of corticosteroids on hyposmia in persistent allergic rhinitis.

Objective: To asses the effects of two topical nasal corticosteroids sprays on hyposmia in patients with persistent allergic rhinitis.

Material And Methods: The study was a prospective clinical trial and it included twenty four patients with persistent allergic rhinitis (PER) and hyposmia (H). The patients were divided into two groups depending on the type of corticosteroid topical nasal spray treatment: group A, 200 micrograms dose of mometasone furoate (MF) and group B, 110 micrograms dose of fluticasone furoate (FF) both administered in the morning for 4 weeks.

Deceased-donor kidney transplantation: improvement in long-term survival.

Background: Despite marked improvement in short-term renal allograft survival rates (GSR) in recent years, improvement in long-term GSR remained elusive.

Methods: We analysed the kidney transplant experience at our centre accrued over four decades to evaluate how short-term and long-term GSR had changed and to identify risk factors affecting graft survival. The study included 1476 adult recipients of a deceased-donor kidney transplant who were transplanted between 1963 and 2006 and who had received one of five distinct immunosuppressive protocols.

Maximum non-reactive concentration of midazolam and ketamine for skin testing study in non-allergic healthy volunteers.

The objective of our study was to determine the maximal non-reactive concentrations for midazolam and ketamine in healthy volunteers using both prick and intradermal skin tests. Twenty-one healthy Caucasian volunteers were tested for midazolam and ketamine using more clustered concentrations (identical for both prick and intradermal tests) than those resulting from decimal dilutions. The criteria for positivity were based on dilutions of drugs that cause wheal and flare reactions in subjects without history of allergy.

Pharmacokinetics of rosuvastatin in patients with end-stage kidney disease undergoing peritoneal dialysis.

Patients undergoing dialysis treatment have a high incidence of dyslipidemia. Rosuvastatin is a potent statin drug that improves overall lipid profiles in dyslipidemic patients. However, the pharmacokinetics of rosuvastatin has not been studied in patients with end-stage kidney disease undergoing chronic peritoneal dialysis (PD).

Interleukin-6 predicts hypoalbuminemia, hypocholesterolemia, and mortality in hemodialysis patients.

Low serum albumin and low serum cholesterol levels are among the most consistent predictors of mortality in patients with end-stage renal disease (ESRD) undergoing hemodialysis. Hypoalbuminemia is often interpreted as a marker of poor nutrition, but serum albumin and cholesterol levels can also be low as part of a cytokine-mediated acute-phase reaction to acute or chronic inflammation. Here we report the results from a 900-day prospective study designed to determine whether tumor necrosis factor-alfa (TNF-alpha) and interleukin-6 (IL-6) predict serum albumin and cholesterol levels and mortality in a group of 90 ambulatory, adult hemodialysis patients with no acute infection, hospitalization or surgery, and no known acquired immunodeficiency syndrome (AIDS), malignancy, or liver disease.

Molecular executors of cell death--differential intrarenal expression of Fas ligand, Fas, granzyme B, and perforin during acute and/or chronic rejection of human renal allografts.

Two distinct cytolytic pathways have been characterized: one in which the interaction between the Fas antigen and its ligand results in apoptosis, and another in which the pore forming protein perforin and the serine protease granzyme B contribute to DNA fragmentation and cell death. We investigated intrarenal expression of these molecular executors of cell death in light of the potential participation of cytolytically active cellular elements in the antiallograft repertory. Reverse transcriptase-polymerase chain reaction was used to identify intrarenal expression of Fas antigen, Fas ligand, granzyme B and perforin in eighty human renal allograft biopsies; mRNA display was correlated with the Banff histological diagnosis of renal allografts.

Intragraft TGF-beta 1 mRNA: a correlate of interstitial fibrosis and chronic allograft nephropathy.

Chronic allograft nephropathy is a relentlessly progressive process and a major cause of long-term graft dysfunction and ultimate failure. Interstitial fibrosis, tubular atrophy, and glomerular and vascular lesions characterize this mechanistically unresolved disorder. Given the prominent role of TGF-beta 1 in tissue repair and in fibrosis, we have explored the hypothesis that fibrosis and chronic allograft nephropathy would be distinguished by intragraft TGF-beta 1 mRNA expression.

Intragraft expression of IL-10 messenger RNA: a novel correlate of renal allograft rejection.

A major conceptual advance is the formulation that type I cytokines (such as IL-2 and IFN-gamma) enhance cellular immunity and are host-protective, and that type II cytokines (such as IL-4 and IL-10) dampen cellular immunity and facilitate the progression of infection. We have explored the intragraft expression of type I and type II cytokines during human renal allograft rejection. RNA was isolated from 98 allograft biopsies, and reverse transcription-PCR was used to amplify and identify intragraft expression of mRNA encoding IL-2, IFN-gamma, IL-4, or IL-10.
