- Aims The HERMES (HEart failure Molecular Epidemiology for Therapeutic targets) consortium aims to identify the genomic and molecular basis of heart failure. Methods and results The consortium currently includes 51 studies from 11 countries, including 68 157 heart failure cases and 949 888 controls, with data on heart failure events and prognosis. All studies collected biological samples and performed genome-wide genotyping of common genetic variants. The enrolment of subjects into participating studies ranged from 1948 to the present day, and the median follow-up following heart failure diagnosis ranged from 2 to 116 months. Forty-nine of 51 individual studies enrolled participants of both sexes; in these studies, participants with heart failure were predominantly male (34-90%). The mean age at diagnosis or ascertainment across all studies ranged from 54 to 84 years. Based on the aggregate sample, we estimated 80% power to genetic variant associations with risk of heart failure with an odds ratio of >1.10 for common variants (allele frequency > 0.05) and >1.20 for low-frequency variants (allele frequency 0.01-0.05) at P < 5 x 10(-8) under an additive genetic model. Conclusions HERMES is a global collaboration aiming to (i) identify the genetic determinants of heart failure; (ii) generate insights into the causal pathways leading to heart failure and enable genetic approaches to target prioritization; and (iii) develop genomic tools for disease stratification and risk prediction.

- Heart failure (HF) is a leading cause of morbidity and mortality worldwide. A small proportion of HF cases are attributable to monogenic cardiomyopathies and existing genome-wide association studies (GWAS) have yielded only limited insights, leaving the observed heritability of HF largely unexplained. We report results from a GWAS meta-analysis of HF comprising 47,309 cases and 930,014 controls. Twelve independent variants at 11 genomic loci are associated with HF, all of which demonstrate one or more associations with coronary artery disease (CAD), atrial fibrillation, or reduced left ventricular function, suggesting shared genetic aetiology. Functional analysis of non-CAD-associated loci implicate genes involved in cardiac development (MYOZ1, SYNPO2L), protein homoeostasis (BAG3), and cellular senescence (CDKN1A). Mendelian randomisation analysis supports causal roles for several HF risk factors, and demonstrates CAD-independent effects for atrial fibrillation, body mass index, and hypertension. These findings extend our knowledge of the pathways underlying HF and may inform new therapeutic strategies.

- (Abstracted from N Engl J Med 2023;388(23):2132-2144) Gestational diabetes mellitus is a common pregnancy complication. It is associated with adverse outcomes, including preeclampsia, obstetrical intervention, large-for-gestational-age neonates, shoulder dystocia, birth trauma, and neonatal hypoglycemia. Cohort studies have found that women with hyperglycemia before 20 weeks of gestation are more likely to experience accelerated fetal growth by 24 to 28 weeks than those diagnosed with GDM later in pregnancy.

- Introduction & Objectives: Antibiotic prophylaxis are administered as a routine to decrease the risk for septic complications following transrectal prostate biopsy. Fosfomycin administered 1 h or more prior to biopsy has equal or better infectious complication rates as compared to Ciprofloxacin in both prospective and retrospective studies from countries with high rates of antibiotic resistance. The aim of this study was to investigate if Fosfomycin administered immediately prior to prostate biopsy was as effective as Ciprofloxacin in Sweden, a country with low rates of antibiotic resistance.Materials & Methods: A randomized, controlled, open, multicenter, non-inferiority-study including men of all ages undergoing transrectal prostate biopsy was performed in the urology departments of three Swedish hospitals. The total number of patients were planned for 3448, divided into low and high infection risk groups. The low-risk group was randomized to either one dose of Fosfomycin 3g or Ciprofloxacin 750mg before biopsy. The high-risk group was randomized to either two doses of Fosfomycin 3g prior to biopsy and one more 24 h after biopsy or Ciprofloxacin 500mg once prior to biopsy and then twice daily for three days. The drugs were administered orally. All patients had a rectal swab for culture before and after biopsy. The endpoint was hospitalisation due to urinary tract infection within 14 days from biopsy, follow-up was performed with a phone interview.Results: The safety board prematurely interrupted the study after 42 included patients due to an unusual high number of hospitalisations. Four out of 20 patients (20%), three in the low-risk group and one in the high-risk group, had been hospitalised due to urosepsis in the Fosfomycin group. One further patient described fever symptoms but did not seek health care. No patient in the Ciprofloxacin group (n=21) described symptoms of infection from the urinary tract. One patient was lost to follow-up. A one-sided binomial test showed a p-value of <0.001. Two of the four hospitalised patients had a positive blood culture for Pseudomonas Aeruginosa and one had a positive rectal swab culture for Pseudomonas species both before and after biopsy.Conclusions: The study does not support the use of Fosfomycin administered immediately prior to prostate biopsy. The results may have been affected by the unexpected high number of Pseudomonas infections, a bacteria where Fosfomycin often lack effect. If Fosfomycin is to be used it should be with caution if Pseudomonas has been seen in earlier cultures

- The NNBAR experiment for the European Spallation Source will search for free neutrons converting to antineutrons with a sensitivity improvement of three orders of magnitude compared to the last such search. This paper describes progress towards a conceptual design report for NNBAR. The design of a moderator, neutron reflector, beamline, shielding and annihilation detector is reported. The simulations used form part of a model which will be used for optimisation of the experiment design and quantification of its sensitivity.

Measurement of single top-quark production in association with a W boson in the single-lepton channel at √s=8TeV with the ATLAS detector

- The production cross-section of a top quark in association with a W boson is measured using proton–proton collisions at s√=8TeV. The dataset corresponds to an integrated luminosity of 20.2fb−1, and was collected in 2012 by the ATLAS detector at the Large Hadron Collider at CERN. The analysis is performed in the single-lepton channel. Events are selected by requiring one isolated lepton (electron or muon) and at least three jets. A neural network is trained to separate the tW signal from the dominant tt¯ background. The cross-section is extracted from a binned profile maximum-likelihood fit to a two-dimensional discriminant built from the neural-network output and the invariant mass of the hadronically decaying W boson. The measured cross-section is σtW=26±7pb, in good agreement with the Standard Model expectation.

Anger and disgust shape judgments of social sanctions across cultures, especially in high individual autonomy societies
- 2024

Tidskriftsartikel (refereegranskat)abstract
- When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip. Moreover, we find that the experience of anger is consistently the strongest predictor of judgments of confrontation, compared to other emotions. Although the link between state-based emotions and judgments may seem universal, its strength varies across countries. Aligned with theoretical predictions, this link is stronger in societies, and among individuals, that place higher value on individual autonomy. Thus, autonomy values may increase the role that emotions play in guiding judgments of social sanctions.

- The associated production of a Higgs boson with a W or Z boson decaying into leptons and where the Higgs boson decays to a bb¯ pair is measured in the high vector-boson transverse momentum regime, above 250 GeV, with the ATLAS detector. The analysed data, corresponding to an integrated luminosity of 139 fb−1, were collected in proton–proton collisions at the Large Hadron Collider between 2015 and 2018 at a centre-of-mass energy of s=13 TeV. The measured signal strength, defined as the ratio of the measured signal yield to that predicted by the Standard Model, is 0.72−0.36 +0.39 corresponding to an observed (expected) significance of 2.1 (2.7) standard deviations. Cross-sections of associated production of a Higgs boson decaying into b quark pairs with a W or Z gauge boson, decaying into leptons, are measured in two exclusive vector boson transverse momentum regions, 250–400 GeV and above 400 GeV, and interpreted as constraints on anomalous couplings in the framework of a Standard Model effective field theory. © 2021 The Author
