The aim of this study is to investigate the association between adherence to beta-blocker treatment after a first acute myocardial infarction (AMI) and long-term risk of heart failure (HF) and death.

All patients admitted for a first AMI included in the nationwide Swedish web-system for enhancement and development of evidence-based care in heart disease evaluated according to recommended therapies register between 2005 and 2010 were eligible (n=71638). After exclusion of patients who died in-hospital, patients with previous HF, patients with unknown left ventricular ejection fraction (EF), and patients who died during the first year after the index event, 38608 patients remained in the final analysis. Adherence to prescribed beta-blockers was determined for 1year after the index event using the national registry for prescribed drugs and was measured as proportion of days covered, the ratio between the numbers of days covered by the dispensed prescriptions and number of days in the period. As customary, a beta-blockers within the first year. Adherence was independently associated with improved long-term outcomes; however, uncertainty remains for patients with HFNEF and NEF.

Nearly one in three AMI patients was non-adherent to beta-blockers within the first year. Adherence was independently associated with improved long-term outcomes; however, uncertainty remains for patients with HFNEF and NEF.

A common limit of the widely used risk scores for preoperative assessment is the lack of information about aspects linked to frailty that may affect outcome, especially in the setting of elderly patients undergoing urological surgery. Frailty has recently been introduced as an additional characteristic to be assessed for better identifying patients at risk of negative outcomes.

To examine the evidence for recent advances in preoperative assessment in patients undergoing urological surgery focussing on the detrimental effect of frailty on outcome, including major (mPCs) and total postoperative complications (tPCs), discharge to a facility, and mortality. The secondary aim was to establish which cut-off scores of the modified Frailty Index (mFI, 11 items) and/or simplified FI (sFI, five items) predicted PCs.

We searched PubMed, the Excerpta Medica database (EMBASE), Cochrane Library and clinicaltrial.gov from inception to 31 May 2020. Studies reporting relationships between the investigated outcomes and patients undergoing major urological surgery. Either a mFi of ≥2 or sFI of ≥3 should be considered potential 'red flags' for preoperative risk assessment and decision-making. There is not enough evidence to confirm the necessity to perform frailty assessment in minor urological surgery.Coiled-Coil Domain Containing Protein 186 (CCDC186) is hypothesized to play an important role in the biogenesis of dense-core vesicles in neurons and endocrine cells. Biallelic loss-of-function variants in the encoding gene CCDC186 have been suggested as a candidate gene for a neurodevelopmental phenotype, but only one patient has been described so far. We report a second patient with a CCDC186-associated phenotype presenting with developmental delay, epileptic encephalopathy, and failure to thrive. Exome sequencing identified a homozygous loss-of-function variant in CCDC186 (NM_018017.2) c.767C> G; p.(Ser256Ter) thus providing further evidence to support CCDC186 as a new disease gene for an autosomal recessive neurodevelopmental disorder.Since its first detection in 1998, avian influenza virus (AIV) subtype H9N2 has been enzootic in Iran. To better understand the evolutionary history of H9N2 viruses in Iran, we sequenced 15 currently circulating H9N2 viruses from domestic poultry during 2017-2019 and performed phylogenetic analysis of complete genome sequences. Phylogenetic analyses indicated that the Iranian H9N2 viruses formed multiple well-supported monophyletic groups within the G1-lineage of H9N2 virus. Our analysis of viral population dynamics revealed an increase in genetic diversity until 2007, corresponding to the multiple introductions and diversification of H9N2 viruses into multiple genetic groups (named Iran 1-4 subgroups), followed by a sudden decrease after 2008. Only the Iran 4 subgroup has survived, expanded, and currently circulates in Iran. The H9N2 viruses possessed many molecular markers associated with mammalian adaption in all gene segments, except neuraminidase gene. Considering the presence of mammalian host-specific markers, the public health threat of H9N2 viruses continues. Molecular analysis showed that Iranian H9N2 strains have continued to evolve and recent strains have multiple amino acid changes and addition of potential N-glycosylation on the antigenic sites of haemagglutinin. Continued antigenic and molecular surveillance of H9N2 viruses in poultry and mammals would be required to monitor further increments in viral evolution and their potential threat to public health.Mechanistic population models are gaining considerable interest in ecological risk assessment. The dynamic energy budget approach for toxicity (DEBtox) and the general unified threshold model for survival (GUTS) are well-established theoretical frameworks that describe sublethal and lethal effects of a chemical stressor, respectively. However, there have been limited applications of these models for mixtures of chemicals, especially to predict long-term effects on populations. We used DEBtox and GUTS in an individual-based model (IBM) framework to predict both single and combined effects of copper and zinc on Daphnia magna populations. The model was calibrated based on standard chronic toxicity test results with the single substances. EGFR inhibitors list A mixture toxicity implementation based on the general independent action model for mixtures was developed and validated with data from a population experiment with copper and zinc mixtures. Population-level effects of exposure to individual metals were accurately predicted by DEB-IBM. The DEB-IBM framework also allowed us to identify the potential mechanisms underlying these observations. Under independent action the DEB-IBM was able to predict the population dynamics observed in populations exposed to the single metals and their mixtures (R2  > 65% in all treatments). Our modeling shows that it is possible to extrapolate from single-substance effects at the individual level to mixture toxicity effects at the population level, without the need for mixture toxicity data at the individual level from standard mixture toxicity tests. The application of such modeling techniques can increase the ecological realism in risk assessment. Environ Toxicol Chem 2021;40513-527. © 2020 SETAC.
