Availability of anesthetic effect monitoring: utilization, intraoperative management and time to extubation in liver transplantation.

Titration of volatile anesthetics to anesthetic effect monitoring using the bispectral index (BIS) has been shown to decrease anesthetic requirements and facilitate recovery from anesthesia unrelated to liver transplantation (OLT). To determine whether availability of such monitoring influences its utilization pattern and affect anesthetic care and outcomes in OLT, we conducted a retrospective analysis in recipients with and without such monitoring. We evaluated annual BIS utilization over a period of 7 years, and compared 41 BIS-monitored patients to 42 controls.

Adjusting the pH of lidocaine for reducing pain on injection.

Background: Lidocaine administration produces pain due to its acidic pH.

Objectives: The objective of this review was to determine if adjusting the pH of lidocaine had any effect on pain resulting from non-intravascular injections in adults and children. We tested the hypothesis that adjusting the pH of lidocaine solution to a level closer to the physiologic pH reduces this pain.

Transverse-momentum and pseudorapidity distributions of charged hadrons in pp collisions at square root of s = 7 TeV.

Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at square root of s = 7  TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit pairs, and fully reconstructed charged-particle tracks. The combination of the three methods gives a charged-particle multiplicity per unit of pseudorapidity dN(ch)/dη|(|η|<0.

Dose patterns in commercially insured subjects chronically exposed to opioids: a large cohort study in the United States.

Background: Little data exist on how opioid doses vary with the length of exposure among chronic opioid users.

Methods: To characterize the change in the dosage of opioids over time, a retrospective cohort study using the PharMetrics database for the years 1999 through 2008 was conducted. Individuals exposed to opioids in 2000 who had 2 opioid dispensings at least 6 months apart and were opioid naive (did not receive any opioid 6 month before their exposure in 2000) were included.

Transcriptome analysis of genes controlled by luxS/autoinducer-2 in Salmonella enterica serovar Typhimurium.

The enteric pathogen Salmonella enterica serovar Typhimurium uses autoinducer-2 (AI-2) as a signaling molecule. AI-2 requires the luxS gene for its synthesis. The regulation of global gene expression in Salmonella Typhimurium by luxS/AI-2 is currently not known; therefore, the focus of this study was to elucidate the global gene expression patterns in Salmonella Typhimurium as regulated by luxS/AI-2.

The reactions of S-phenyl, S-(4-chlorophenyl), and S-(2,3,4,5,6-pentafluorophenyl) 4-nitrophenyl thiocarbonates (9, 11, and 16, respectively) with a series of secondary alicyclic (SA) amines and those of S-(4-methylphenyl) 4-nitrophenyl thiocarbonate (8) and compounds 9 and 11 with a series of phenols are subjected to a kinetic investigation in 44 wt % ethanol-water, at 25.0 degrees C and an ionic strength of 0.2 M.

Preliminary study for evaluation of avian influenza virus inactivation in contaminated poultry products using electron beam irradiation.

Spread of avian influenza is associated with movement of infected poultry and poultry products, and, as a result, strict international trade restrictions are in place. In addition, the possibility of transmission of avian influenza virus (AIV) strains to mammalian species by the consumption or handling of infected poultry, although a rare occurrence, is an important trade concern. Traditional methods for poultry product decontamination, such as thermal processing, are effective in inactivating AIV.

Rapid concentration of Bacillus and Clostridium spores from large volumes of milk, using continuous flow centrifugation.

Deliberate or accidental contamination of foods such as milk, soft drinks, and drinking water with infectious agents or toxins is a major concern to health authorities. There is a critical need to develop technologies that can rapidly and efficiently separate and concentrate biothreat agents from food matrices. A key limitation of current centrifugation and filtration technologies is that they are batch processes with extensive hands-on involvement and processing times.

Antifibrinolytic agents for reducing blood loss in scoliosis surgery in children.

Background: Scoliosis surgery is often associated with substantial blood loss and potential detrimental effects in children. Antifibrinolytic agents are often used to reduce perioperative blood loss. Clinical trials have evaluated their effect in children undergoing surgical correction of scoliosis but no systematic review has been published.

Grapefruit juice and its furocoumarins inhibits autoinducer signaling and biofilm formation in bacteria.

Cell-to-cell communications in bacteria mediated by small diffusible molecules termed as autoinducers (AI) are known to influence gene expression and pathogenicity. Oligopeptides and N-acylhomoserine lactones (AHL) are major AI molecules involved in intra-specific communication in gram-positive and gram-negative bacteria respectively, whereas boronated-diester molecules (AI-2) are involved in inter-specific communication among both gram-positive and gram-negative bacteria. Naturally occurring furocoumarins from grapefruit showed >95% inhibition of AI-1 and AI-2 activities based on the Vibrio harveyi based autoinducer bioassay.

Autoinducer AI-2 is involved in regulating a variety of cellular processes in Salmonella Typhimurium.

Salmonella Typhimurium is known to exhibit LuxS/AI-2-mediated cell signaling. We investigated the role of LuxS/AI-2 system on Salmonella Typhimurium protein expression using a proteomics approach based on two-dimensional gel electrophoresis (2DGE)-MALDI-MS. The global protein expression profiles of the wild-type, a luxS mutant, and a luxS mutant strain supplemented with AI-2 were compared.

Emotional disclosure through patient narrative may improve pain and well-being: results of a randomized controlled trial in patients with cancer pain.

Narrative medicine is based upon physicians' awareness of patients' narration of their suffering, their hopes, and how illness has affected them. It offers a model for improving health outcomes. To determine whether incorporating a narrative approach in patients with cancer decreases pain intensity and improves their global sense of well-being, we performed a randomized, single-blind controlled trial in adult patients with cancer and average pain intensity levels of at least 5/10.

An N-of-1 trial as an aid to decision-making prior to implanting a permanent spinal cord stimulator.

Objective: Limited evidence supports the efficacy of spinal cord stimulation (SCS). Therefore, it is crucial to assess the usefulness of this invasive procedure before implanting permanent electrodes in each patient. An N-of-1 trial is an experiment in which a single participant undergoes periods of comparative treatments.

Identification of ground beef-derived fatty acid inhibitors of autoinducer-2-based cell signaling.

Autoinducer-2 (AI-2) molecules are used by several microorganisms to modulate various processes, including bioluminescence, biofilm formation, and virulence expression. Certain food matrices, including ground beef extracts, possess compounds capable of inhibiting AI-2 activity. In the present study, we identified and characterized these AI-2 inhibitors from ground beef extract using hexane solvent extraction and gas chromatography.

Proteomic analysis to identify the role of LuxS/AI-2 mediated protein expression in Escherichia coli O157:H7.

Microorganisms employ autoinducer molecules to modulate various bacterial processes including virulence expression, biofilm development, and bioluminescence. The universal autoinducer molecule AI-2 is hypothesized to mediate cell signaling in Escherichia coli O157:H7. We investigated the role of AI-2 on the E.

Continuous lumbar plexus block provides improved analgesia with fewer side effects compared with systemic opioids after hip arthroplasty: a randomized controlled trial.

Background And Objectives: A single injection lumbar plexus block for acute pain management after hip surgery is usually limited to the immediate postoperative period. We conducted a randomized controlled trial to determine the effect of a continuous lumbar plexus block on perioperative opioid requirements and pain intensity.

Methods: Adult patients undergoing elective hip arthroplasty under general anesthesia were randomized to continuous lumbar plexus block combined with patient-controlled analgesia (PCA) or PCA only for postoperative pain.

Extent of right hepatectomy determines postoperative donor albumin and bilirubin changes: new insights.

Background: Changes in donor plasma albumin (Alb) and bilirubin (Tbili) are common following right hepatectomy for liver transplantation. We conducted a retrospective study to determine whether the size of the liver resection and the estimated blood loss (EBL) impact these laboratory values in the first week (early) and third week (late) postoperatively.

Methods: Demographics and peri-operative data of 34 donors undergoing right hepatectomy were analysed by Spearman's correlation (data in means+/-SD, P<0.
