BACKGROUND: Myocardial injury after non-cardiac surgery (MINS) increases the risk of cardiovascular events and deaths, which anticoagulation therapy could prevent. Dabigatran prevents perioperative venous thromboembolism, but whether this drug can prevent a broader range of vascular complications in patients with MINS is unknown. The MANAGE trial assessed the potential of dabigatran to prevent major vascular complications among such patients. METHODS: In this international, randomised, placebo-controlled trial, we recruited patients from 84 hospitals in 19 countries...

In view of the gastrointestinal problems generated by the ketoprofen use, the ketoprofen association with omeprazole is available on the market. However, this association efficacy in acute pain control has not been established. Bilateral extraction of lower third molars in similar positions is currently the most used model for the evaluation and investigation of the efficacy and pharmacological effects of new compounds for the treatment of acute postoperative pain. The randomized and crossover study consisted in evaluating the clinical efficacy of therapy performed by ketoprofen 100 mg (twice daily-b...

The overreaching purpose of this study is to evaluate new approaches for determining the optimal operational and column conditions in chromatography laboratories, i.e., how best to select a packing material of proper particle size and how to determine the proper length of the column bed after selecting particle size. As model compounds, we chose two chiral drugs for preparative separation: omeprazole and etiracetam. In each case, two maximum allowed pressure drops were assumed: 80 and 200 bar. The processes were numerically optimized (mechanistic modeling) with a general rate model using a global optimization method...

BACKGROUND: Adverse drug reactions (ADRs), also called as drug adverse events (AEs), are reported in the FDA drug labels; however, it is a big challenge to properly retrieve and analyze the ADRs and their potential relationships from textual data. Previously, we identified and ontologically modeled over 240 drugs that can induce peripheral neuropathy through mining public drug-related databases and drug labels. However, the ADR mechanisms of these drugs are still unclear. In this study, we aimed to develop an ontology-based literature mining system to identify ADRs from drug labels and to elucidate potential mechanisms of the neuropathy-inducing drugs (NIDs)...

Mycobacterium vaccae , a bacterium found in soil, has been receiving attention as adjuvant to antituberculosis treatment, vaccines and immunotherapies and even as antidepressant. This bacterium is also able to degrade several pollutants, including aromatic compounds. The increasing presence of organic solvents in the environment may lead to M. vaccae adapted populations. A possible relationship between solvent tolerance and decreased susceptibility to other types of chemicals, including antibiotics, may pose a problem during opportunistic infections...

INTRODUCTION: Roux-en-Y gastric bypass (GBP) is associated with changes in cardiometabolic risk factors and bioavailability of drugs, but whether these changes are induced by calorie restriction, the weight loss or surgery per se, remains uncertain. The COCKTAIL study was designed to disentangle the short-term (6 weeks) metabolic and pharmacokinetic effects of GBP and a very low energy diet (VLED) by inducing a similar weight loss in the two groups. METHODS AND ANALYSIS: This open, non-randomised, three-armed, single-centre study is performed at a tertiary care centre in Norway...

1. Albumin has reportedly enhanced cytochrome P450 (P450)-mediated drug oxidation rates in human liver microsomes. Consequently, measurements of clearances and fractions metabolized could vary depending on the experimental albumin concentrations used. 2. In this study, the oxidation rates of diclofenac and warfarin by human liver microsomes were significantly enhanced in the presence of 0.10% (w/v) bovine serum albumin, whereas those of tolbutamide and phenytoin required 1.0% and 2.0% of albumin for significant enhancement...

Omeprazole was first evaluated for its antityrosinase activity and preservation of fresh-cut apples. The results obtained from enzymic analyses showed that the omeprazole inhibited tyrosinase activity (IC50  = 40 ± 1.2 μM) with a reversible and competitive mechanism. Fluorescence quenching assays demonstrated that the interaction between omeprazole and tyrosinase was driven by hydrophobic forces and hydrogen bonds in a static procedure. Molecular docking further revealed that hydrogen bonds and hydrophobic forces were generated by omeprazole with the amino acid residues located in the A chain of tyrosinase...

Clindamycin is a lincomycin-derived antibiotic useful for the treatment of anaerobic and Gram-positive aerobic bacterial infections. Cutaneous adverse reactions are usually maculopapular exanthemas, although hypersensitivity syndrome, acute generalized exanthematous pustulosis, and Stevens-Johnson syndrome have also been reported (1). We report the case of a patient with a maculopapular rash triggered by clindamycin who developed cutaneous lesions on striae distensae (SD). A 47-year-old woman was referred to our clinic for pruritic cutaneous lesions which had started 6 days earlier...
