BACKGROUND: It has been hypothesized that adaptation of health practice guidelines to the local setting is expected to improve their uptake and implementation while cutting on required resources. We recently adapted the published American College of Rheumatology (ACR) Rheumatoid Arthritis (RA) treatment guideline to the Eastern Mediterranean Region (EMR). The objective of this paper is to describe the process used for the adaptation of the 2015 ACR guideline on the treatment of RA for the EMR...

Radical activation methods, such as electron transfer dissociation (ETD), produce structural information complementary to collision-induced dissociation. Herein, electron transfer dissociation of 3-fold protonated DNA hexamers was studied to gain insight into the fragmentation mechanism. The fragmentation patterns of a large set of DNA hexamers confirm cytosine as the primary target of electron transfer. The reported data reveal backbone cleavage by internal electron transfer from the nucleobase to the phosphate linker leading either to a•/w or d/z• ion pairs...

Clinicians do not have the time or resources to consider the underlying evidence for the myriad decisions they must make each day and, as a consequence, rely on recommendations from clinical practice guidelines. Guideline panels should consider all the relevant factors (criteria) that influence a decision or recommendation in a structured, explicit, and transparent way and provide clinicians with clear and actionable recommendations. In this article, we will describe the EtD frameworks for clinical practice recommendations...

Matrix-assisted ionization (MAI) is a recently developed ionization technique that produces multiply charged ions on either electrospray ionization (ESI) or matrix-assisted laser desorption/ionization (MALDI) platform without the need of high voltage or laser ablation. In this study, MAI has been coupled to a high resolution accurate mass (HRAM) hybrid instrument, the Orbitrap Elite mass spectrometer, with electron transfer dissociation (ETD) module for fast peptide and intact protein characterization. The softness of MAI process preserves labile post-translational modifications (PTM) and allows fragmentation and localization by ETD...

Glycosylation is among the most abundant and diverse protein post-translational modifications (PTMs) identified to date. The structural analysis of this PTM is challenging due to the diverse monosaccharides which are not conserved among organisms, the branched nature of glycans, their isomeric structures, and heterogeneity in the glycan distribution at a given site. Glycoproteomics experiments have adopted the traditional high-throughput LC-MS(n) proteomics workflow to analyze site-specific glycosylation. However, comprehensive computational platforms for data analyses are scarce...

Etoricoxib features antioxidant and anti-inflammatory properties concomitantly, suggesting that it may be beneficial in testicular ischemia reperfusion (I/R) damage. Our aim is to investigate the effects of etoricoxib on testicular I/R damage induced with torsion-detorsion (TD). The etoricoxib + torsion-detorsion (ETD) groups of animals were given etoricoxib in 50 and 100 mg/kg of body weight (ETD-50 and ETD-100), while the testes torsion-detorsion (TTD) and sham operation rat group (SOG) animals were given single oral doses of distilled water as a solvent...

The objective of our case-control study was to determine whether craniofacial features on lateral nasopharyngeal radiographs (LNPRs) can predict eustachian tube dysfunction (ETD). The study included patients seen in the otolaryngology clinic from 2005 to 2011. Patients 0 to 10 years old with pressure equalization tube (PET) placement and LNPR within 6 months were included. Measurements were compared with age-matched controls selected at random to identify craniofacial features associated with ETD. Using receiver operating curve methodology, selected measurements were used to correlate age, craniofacial features, and ETD...

Clinicians, guideline developers, and policymakers sometimes neglect important criteria, give undue weight to criteria, and do not use the best available evidence to inform their judgments. Explicit and transparent systems for decision making can help to ensure that all important criteria are considered and that decisions are informed by the best available research evidence. The GRADE Working Group has developed Evidence to Decision (EtD) frameworks for the different type of recommendations or decisions. The purpose of EtD frameworks is to help people use evidence in a structured and transparent way to inform decisions in the context of clinical recommendations, coverage decisions, and health system or public health recommendations and decisions...

Electron transfer dissociation (ETD) is becoming increasingly important in mass spectrometry-based analysis of peptides and proteins. Supplemental collisional activation of undissociated electron transfer products can significantly increase fragmentation yield and sequence coverage, but hydrogen rearrangements - specifically, transfer of a hydrogen radical from a c to a z fragment - lead to distorted isotope distributions and increased potential for signal overlap. Concomitant collisional activation during the ion/ion reaction significantly reduces these rearrangements, but, in ion traps, also leads to lower reaction rates and reduced overlap of anion and cation clouds...

The functional interactions of carbohydrates and their protein receptors are the basis of biological events critical to the evolution of pathological states. Hence, for the past years, such interactions have become the focus of research for the development of therapeutics and discovery of novel glycan biomarkers based on their binding affinity. Due to the high sensitivity, throughput, reproducibility, and capability to ionize minor species in heterogeneous mixtures, microfluidics-mass spectrometry (MS) has recently emerged as a method of choice in protein-glycan interactomics...

With the advent of new methodologies, proteomics-based assays are increasingly used to study the efficacy of drugs on a molecular level. For these studies to be meaningful, the proteomics assays need to be sensitive, selective, accurate, and reproducible. This is often accomplished through a targeted approach, either using single or multiple reaction monitoring (SRM/MRM) or, more recently, parallel reaction monitoring (PRM). In PRM, the parallel detection of all product ions in a high-resolution mass spectrometer affords higher selectivity than SRM/MRM...

Sleep-disordered breathing (SDB) and Eustachian tube disorders (ETDs) share the same risk factors. The specific aim of this study was to determine the correlation between these 2 conditions and to determine whether treatments for SDB reduce the risk of ETD.This is a retrospective and large population-based cohort study. According to Taiwan's National Health Insurance Research Database, out of 1,000,000 insured patients, 24,251 patients were newly diagnosed with SDB from year 2000 through 2009. The control group for this study comprised 96,827 patients without SDB who were randomly selected from the same database at a ratio of 1:4, frequency matched for sex, age, and index year of SDB...

PURPOSE: To propose a new formalism allowing the characterization of human tissues from multi-energy computed tomography (MECT) data affected by noise and to evaluate its performance in estimating proton stopping powers (SPR). METHODS: A recently published formalism based on principal components analysis called eigentissues decomposition (ETD) is adapted to the context of noise using a Bayesian estimator. The method, named Bayesian ETD, uses the maximum a posteriori fractions of eigentissues in each voxel to determine physical parameters relevant for proton beam dose calculation...

Eustachian tube dysfuntion intends to describe a variety of signs, symptoms, and physical findings that result from the impairment of ET function. A large variety of methods have been employed to assess ET function in the literature. Due to the lack of high level evidence, it is difficult to draw conclusions on the effectiveness of medical and surgical treatments. There are various medical and surgical interventions available for chronic obstructive ET dysfunction including balloon Eustachian tuboplasty (BET) and laser or microdebrider tuboplasty...

High resolution mass spectrometry is a key technology for in-depth protein characterization. High-field Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) enables high-level interrogation of intact proteins in the most detail to date. However, an appropriate complement of fragmentation technologies must be paired with FTMS to provide comprehensive sequence coverage, as well as characterization of sequence variants, and post-translational modifications. Here we describe the integration of front-end electron transfer dissociation (FETD) with a custom-built 21 tesla FT-ICR mass spectrometer, which yields unprecedented sequence coverage for proteins ranging from 2...

OBJECTIVES: The PLATO trial revealed superiority of ticagrelor over clopidogrel for the prevention of atherothrombotic events in patients with acute coronary syndrome. However, adverse events such as bleeding, dyspnea, and bradycardia were frequently reported, potentially leading to excess early ticagrelor discontinuation (ETD), later confirmed in the PEGASUS trial. We here evaluated the incidence and causes for ETD in a real-world patient cohort in a high-volume nonacademic percutaneous coronary intervention center in the Netherlands...
