INTRODUCTION: Information regarding adverse drug reactions (ADRs) of new medications is based on clinical studies of selected populations. The reporting of ADRs from real-life use following the marketing of new active substances is instrumental for the continuous evaluation of their benefit-risk balance. The aim of this study was to determine the number and nature of ADR reports in Iceland and compare with other Nordic countries. MATERIALS AND METHODS: Reports of ADRs from 2013 to 2016 were examined using the Icelandic Medicines Agency´s database...

Colonoscopy quality, as measured by adenoma detection rates, varies widely across providers and is inversely related with patients' post-colonoscopy cancer risk. This has unknown consequences for the benefits of faecal immunochemical testing (FIT) versus primary colonoscopy screening for colorectal cancer. Using an established microsimulation model, we predicted the lifetime colorectal cancer incidence and mortality benefits of annual FIT versus ten-yearly colonoscopy screening at differing ADR levels (quintiles; averages 15...

Electronic health records (EHRs) linked with biobanks have been recognized as valuable data sources for pharmacogenomic studies, which require identification of patients with certain adverse drug reactions (ADRs) from a large population. Since manual chart review is costly and time-consuming, automatic methods to accurately identify patients with ADRs have been called for. In this study, we developed and compared different informatics approaches to identify ADRs from EHRs, using clopidogrel-induced bleeding as our case study...

BACKGROUND AND AIMS: Adenoma detection rate (ADR) has been established as a quality indicator for screening colonoscopy. Because ADR is cumbersome to obtain in routine practice, polyp detection rate (PDR), polypectomy rate (PR) and adenoma-to-polyp-detection-rate-ratio (APDRR) have been proposed to estimate ADR. This study aimed to evaluate APDRR in order to estimate ADR (ADRest) in different settings. METHODS: Average risk screening and surveillance colonoscopies from a community-based private practice and a tertiary academic hospital setting were retrospectively evaluated...

Multidrug resistance (MDR) is a huge obstacle in cancer chemotherapeutics. Overcoming MDR is a great challenge for anticancer drug discovery. Here, DNA binding and cytotoxicity of Schiff base L1 and L2 were explored to assess their efficiency in fighting cancer and overcoming the MDR. L1 and L2 could treat extremely chemoresistant MCF-7/ADR cell as drug-sensitive cell, with drug resistance index (DRI) <2.13, showing high potential in overcoming the MDR. The apoptotic ratio induced by L1 and L2 was low for both MCF-7 and MCF-7/ADR cells...

Overexpression of P-glycoprotein (Pgp) has been considered a primary cause for multidrug resistance in a variety of cancers for three decades. However, clinical translation of Pgp targeted therapeutics has been hindered by lack of patient preselection based on the Pgp presence in tumors. We aim to develop a molecularly targeted probe for imaging tumoral Pgp in vivo with positron emission tomography (PET) and fluorescence, and to provide a tool for preselecting the patients with tumoral Pgp expression. Thus, a Pgp monoclonal antibody 15D3 was chemically modified with IRDye800 (IR800) and DOTA chelator...

BACKGROUND: Adenoma detection rate (ADR) is a quality indicator for screening colonoscopy, but its calculation is time-consuming. Polyp detection rate (PDR) has been found to correlate with ADR; however, its use as a quality indicator has been criticized out of concern for endoscopists artificially inflating the PDR. We aim to evaluate whether active monitoring affects PDR. METHODS: In March 2015, 14 endoscopists were made aware that their personal PDRs would be tracked monthly as a quality improvement project...

2A peptide discovered in Picornaviridae is capable of self-cleavage providing an opportunity to carry out synthesis of several proteins using one transcript. Dissociation in the 2A sequence during translation leads to the individual proteins formation. We constructed cDNA including genes of the bovine cholesterol hydroxylase/lyase (CHL) system proteins-cytochrome P450scc (CYP11A1), adrenodoxin (Adx) and adrenodoxin reductase (AdR), that are fused into a single ORF using FMDV 2A nucleotide sequences. The constructed vectors direct the expression of cDNA encoding polyprotein P450scc-2A-Adx-2A-AdR (CHL-2A) in Escherichia coli and Saccharomyces cerevisiae...
