Background and Aims: Inflammatory bowel disease [IBD] has been associated with spondyloarthritis [SpA], but population-based estimates are scarce. Here we compare the occurrence of SpA before and after a diagnosis of IBD with the general population, overall and by IBD subtype and age. Methods: We used a nationwide register-based cohort study of 39 203 patients diagnosed with IBD during 2006-2016,
We study photoionization of argon atoms close to the 3s(2)3p(6) -> 3s(1)3p(6)4p Fano resonance using an attosecond pulse train and a weak infrared probe field. An interferometric technique combined with tunable attosecond pulses allows us to determine the phase of the photoionization amplitude as a function of photon energy. We interpret the experimental results using an analytical two-photon mode
AimsAnaemia and iron deficiency are constituents of the cardio-renal syndrome in chronic heart failure (CHF). We investigated the effects of i.v. iron in iron-deficient CHF patients on renal function, and the efficacy and safety of this therapy in patients with renal dysfunction. Methods and resultsThe FAIR-HF trial randomized 459 CHF patients with iron deficiency (ferritin <100 mu g/L, or between
Introduction: Twelve-lead electrocardiogram (ECG) is used to screen for hypertrophic cardiomyopathy (HCM), but up to 25% of HCM patients do not have distinctly abnormal ECGs, whereas up to 5% to 15% of healthy athletes do. We hypothesized that an approximately 5-minute resting advanced 12-lead ECG test ("A-ECG score") could detect HCM with greater sensitivity than pooled conventional ECG criteria
Hydrodeoxygenation (HDO) is a catalytic process applied for the reduction of oxygen levels in hydrocarbons from bio-derived feedstock as part of the processing into renewable fuel. The MoS2-based hydrotreating catalysts, currently being applied for the HDO reaction, are exposed to a complex environment consisting of O-rich hydrocarbons and water, which adversely impacts the state and stability of
This edited volume systematises jurisprudential analysis across various levels and elucidates largely unexplored processes of implementation, both at institutional, regional and national levels. By way of collecting such a diverse body of interpretations and practical experience, it strives to provide a comprehensive and practical article-by-article guide to the United Nations Declaration on the R
Introduction: Oesophageal resection carries significant morbidity and mortality. Artificial intelligence (AI) advances in medical research enable enhanced predictions, flexibility, and interpretability, especially for complex interactions and nonlinear relationships. Material and methods: We used a register-based case-control design nested within prospectively collected data from the Swedish Natio
Gaining insight into structural and compositional transformations occurring at the electrode/electrolyte interface during the operation of electrochemical systems is fundamental to understanding and, thus, optimizing their performance. Such an analysis must be performed in operando conditions, owing to the potential, electrolyte and time dependence of these transformations. Here, the use of X-ray
We report resonant inelastic x-ray scattering (RIXS) spectra of neon atoms interacting with intense x-ray pulses generated using an x-ray free-electron laser (XFEL). We find that an unexpected peak emerges near the Ka line of Ne, which does not coincide with any physical resonances of neon ions. We perform theoretical calculations based on a quantum-state-resolved rate-equation approach with x-ray
FLASHForward is an experimental facility at DESY dedicated to beam-driven plasma-accelerator research. The X-2 experiment aims to demonstrate acceleration with simultaneous beam-quality preservation and high energy efficiency in a compact plasma stage. We report on the completed commissioning, first experimental results, ongoing research topics, as well as plans for future upgrades.
Introduction: HIV guidelines recommend switching from a three-drug regimen (3DR) to dolutegravir + lamivudine (DTG+3TC) for eligible individuals. This retrospective national cohort study used Swedish InfCareHIV registry data to evaluate long-term outcomes of adults with HIV RNA <50 copies/ml who switched to DTG+3TC or a guideline-recommended 3DR between July 2019 and May 2023 in routine clinical c
IntroductionForensic assessments of whether an injury would have been life-threatening often rely on empirical knowledge rather than evidence-based criteria. To address this gap, we applied the validated trauma scoring system New Injury Severity Score (NISS) to estimate mortality risk along the natural course of single stab injuries to the trunk.Methods and materialsWe included 408 survivors and 1
Background: Dementia is a growing public health concern, and although diet is a modifiable potential risk factor, the role of free sugar intake remains unclear. Excess sugar has been linked to metabolic and cardiovascular dysfunction, both associated with cognitive decline, but evidence regarding specific sugar sources is limited. Objectives: This study aimed to investigate the associations betwee
Background and aims: Activation of pancreatic proteases is considered to be a crucial event in the early phase of acute pancreatitis but the cause of this activation is not known. Most cases of acute pancreatitis can be attributed to either gallstone disease or alcohol abuse. However, little is known about other risk factors. The aim of this thesis is to investigate the mechanisms involved in the
This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated. The holographic interferometry technique r
The incidence of Diabetes Mellitus increases globally in epidemic proportions. Type 2 Diabetes is the most prevalent form of Diabetes, comprising 90% of the patients. In Type 2 Diabetes, two processes contribute to the development of the disease: insufficient insulin secretion from the pancreatic ?-cell and insulin resistance of the target organs. This leads to loss of control of blood glucose lev
