Background: To investigate the association between the development of incident interstitial lung disease (ILD) in patients with rheumatoid arthritis (RA) and the disease activity of RA with its various components, especially C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).

Methods: We analysed data from RA patients, observed in the German biologics register RABBIT between 2001 and 2021. In a nested case-control study, patients with a reported incident ILD diagnosis during follow-up were matched 1:5 to patients without ILD.

Article Synopsis
  • The study looks at how the location where doctors put tubes in the arteries for heart support affects brain health after surgery.
  • They compared three methods: using the aorta, subclavian/axillary arteries, and femoral artery to see which had the least brain problems.
  • Results showed that patients using the subclavian/axillary method had more major brain issues compared to the others, and also had more seizures after the surgery.

Aim: To investigate the associations of the Dietary Approaches to Stop Hypertension (DASH) score with subcutaneous (SAT) and visceral (VAT) adipose tissue volume and hepatic lipid content (HLC) in people with diabetes and to examine whether changes in the DASH diet were associated with changes in these outcomes.

Methods: In total, 335 participants with recent-onset type 1 diabetes (T1D) and type 2 diabetes (T2D) from the German Diabetes Study were included in the cross-sectional analysis, and 111 participants in the analysis of changes during the 5-year follow-up. Associations between the DASH score and VAT, SAT and HLC and their changes were investigated using multivariable linear regression models by diabetes type.

Article Synopsis
  • ECLS cannulation in post-cardiotomy patients is uncommon in general wards, with only 39 out of 2058 patients studied undergoing the procedure while at the hospital.
  • The majority of these patients faced complications like acute kidney injury and arrhythmias, with a high in-hospital mortality rate of 84.6%, predominantly due to persistent heart failure.
  • Findings suggest that ECLS cannulation mainly affects low-risk patients who experience cardiac arrest post-surgery, indicating a need for further research into improving outcomes.

Objectives: Although cardiogenic shock requiring extracorporeal life support after cardiac surgery is associated with high mortality, the impact of sex on outcomes of postcardiotomy extracorporeal life support remains unclear with conflicting results in the literature. We compare patient characteristics, in-hospital outcomes, and overall survival between females and males requiring postcardiotomy extracorporeal life support.

Methods: This retrospective, multicenter (34 centers), observational study included adults requiring postcardiotomy extracorporeal life support between 2000 and 2020.

Growing evidence implicates systemic inflammation in the loss of structural brain integrity in natural ageing and disorder development. Chronic stress and glucocorticoid exposure can potentiate inflammatory processes and may also be linked to neuronal atrophy, particularly in the hippocampus and the human neocortex. To improve understanding of emerging maladaptive interactions between stress and inflammation, this study examined evidence for glucocorticoid- and inflammation-mediated neurodegeneration in healthy mid-aged adults.

Searches for new resonances are performed using an unsupervised anomaly-detection technique. Events with at least one electron or muon are selected from 140  fb^{-1} of pp collisions at sqrt[s]=13  TeV recorded by ATLAS at the Large Hadron Collider. The approach involves training an autoencoder on data, and subsequently defining anomalous regions based on the reconstruction loss of the decoder.

A search for events with a dark photon produced in association with a dark Higgs boson via rare decays of the standard model Z boson is presented, using 139  fb^{-1} of sqrt[s]=13  TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider. The dark boson decays into a pair of dark photons, and at least two of the three dark photons must each decay into a pair of electrons or muons, resulting in at least two same-flavor opposite-charge lepton pairs in the final state. The data are found to be consistent with the background prediction, and upper limits are set on the dark photon's coupling to the dark Higgs boson times the kinetic mixing between the standard model photon and the dark photon, α_{D}ϵ^{2}, in the dark photon mass range of [5, 40] GeV except for the ϒ mass window [8.

This Letter reports the observation of single top quarks produced together with a photon, which directly probes the electroweak coupling of the top quark. The analysis uses 139  fb^{-1} of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. Requiring a photon with transverse momentum larger than 20 GeV and within the detector acceptance, the fiducial cross section is measured to be 688±23(stat) _{-71}^{+75}(syst)  fb, to be compared with the standard model prediction of 515_{-42}^{+36}  fb at next-to-leading order in QCD.

Article Synopsis
  • The letter details a study by the ATLAS experiment measuring the nuclear modification factor (R_{AA}) of large-radius jets in high-energy Pb+Pb collisions at 5.02 TeV using data from both Pb+Pb and proton-proton (pp) collisions.
  • The large-radius jets were analyzed using a specific reconstruction algorithm and were measured across a set range of transverse momentum and pseudorapidity.
  • The findings indicate that jets with a more complex internal structure experience greater energy loss (quenching) compared to simpler jets, which provides insights into how jet structure influences jet suppression in nuclear matter.

Article Synopsis
  • - The study investigates the "ridge" phenomenon in high-energy proton-proton (pp) collisions, focusing on the correlation between particles in the underlying event and scattering processes like jets.
  • - Using data from the ATLAS experiment at the LHC, researchers analyzed two-particle correlations in pp collisions at 13 TeV, looking at different configurations with and without charged particles related to jets.
  • - The findings indicate that excluding jet-associated particles does not change the correlations, and there is no significant relationship between jet particles and the underlying event, suggesting that hard scattering does not contribute to the observed ridge effect.

Jet quenching is the process of color-charged partons losing energy via interactions with quark-gluon plasma droplets created in heavy-ion collisions. The collective expansion of such droplets is well described by viscous hydrodynamics. Similar evidence of collectivity is consistently observed in smaller collision systems, including pp and p+Pb collisions.
