Hjärntumörer hos barn är ovanliga och prognosen har förbättrats avsevärt under de senaste decennierna. Eftersom symtomen ofta är diffusa och ospecifika riskerar diagnosen att fördröjas, vilket kan leda till mer avancerad och svårbehandlad sjukdom. Förutom huvudvärk och illamående kan synpåverkan, hormonella rubbningar, motoriska symtom och ryggsmärta vara tidiga varningssignaler. Tidigare upptäckt
Purpose: Right ventricular (RV) dysfunction is the key prognostic factor in pulmonary arterial hypertension (PAH). Progression to RV failure involves dilatation, systolic and diastolic impairment, fibrosis, and metabolic changes. Lung transplantation (LTx) normalizes RV afterload, but the extent of recovery and its relation to immunosuppressive therapy remain unclear. We aimed to assess RV functio
INTRODUCTION: The anterior medial temporal lobe (MTL), including the entorhinal cortex (ERC) and Brodmann area 35 (BA35), is among the earliest cortical sites of tau pathology in Alzheimer's disease (AD), yet conventional image segmentation methods poorly capture these regions. METHODS: We applied an automated segmentation approach using an extended Automatic Segmentation of Hippocampal Subfields
This study characterizes the physicochemical properties and evaluates the atmospheric dispersion of radionuclides potentially released from the European Spallation Source (ESS) under a postulated worst-case loss-of-coolant accident scenario. The primary objective was to quantify near-surface air concentrations and deposition. Likely chemical forms were identified through a literature-based evaluat
Josef Pettersson föddes som yngste son i en soldatfamilj under första halvan av 1800-talet. Han tog arbete som dräng på Dannäs säteri som 17-åring. Artikeln handlar dels om hur han efter en karriär som rättare och kvarnägare och hemmansägare köpte det säteri där han hade sökt arbete som tonåring, dels om hur han och hustrun Lisa startade den första frikyrkoförsamlingen på orten.
Acceptorless alcohol dehydrogenation (AAD) converts alcohols to carbonyl compounds with concurrent hydrogen evolution, providing a sustainable and atom-efficient oxidation pathway. Here, we examine how electronic modifications of POCOP-type iridium pincer catalysts influence this transformation. A CF3-substituted complex exhibits a 3–7 times higher initial turnover frequency relative to the parent
The presence of epistemic uncertainties in probabilistic modeling of structural performance implies that not only one but a multitude of possible models should be considered. When such models are utilized in the context of reliability and risk analysis, this does not pose any particular problem. In fact, epistemic and aleatory uncertainties may be treated without differentiation. However, in the c
Den här studien undersökte hur rapportskapande beteenden, operationaliserade genom HEAAR-principerna (Ärlighet, Empati, Anpassning, Autonomi och Reflektion), samt övertalningstekniker (alpha och omega) predicerar informationslämnande under högrealistisk militär förhörsträning. Sjuttiosex timmar av inspelade förhör (25 krigsfångar och 6 förhörsledare under utbildning) från en högrealistisk militär
Ultracold polar molecular gases provide a powerful platform for exploring quantum many-body physics with strong, long-range, and anisotropic interactions. In this work, we develop an extended Gross-Pitaevskii approach tailored to bosonic dipolar molecules under single-microwave shielding, incorporating their effective interactions and adapting the quantum fluctuation corrections. We benchmark this
Objectives: To investigate the relation between adherence to dietary recommendations, the quantified intake of the components of these recommendations, and the risk of developing giant cell arteritis (GCA). Methods: Participants in the Malmö Diet and Cancer Study cohort who subsequently developed GCA were identified through register linkage and validated in a structured review. Four controls, matc
Background/Objectives: Radiostereometric analysis (RSA) is the gold standard for measuring implant migration, with CT-RSA increasingly used as an alternative. To evaluate CT-RSA, it is important to assess data that include the surrounding soft tissues, rather than data from simplified phantoms, while also avoiding unnecessary radiation from multiple scans. This study proposes a method for generati
BACKGROUND: Early diagnosis and treatment of breast cancer-related arm lymphedema (BCRAL) is essential to prevent progression. Local tissue water (LTW) can be assessed using the tissue dielectric constant (TDC), enabling detection before an increase of arm volume occurs. However, knowledge of the variation of LTW during cancer treatment and appropriate LTW thresholds for early detection of BCRAL i
IntroductionAlthough transcranial sonography (TCS) assessing hyperechogenic substantia nigra (SN+) as biomarker for Parkinsońs disease (PD) has been introduced elsewhere, the clinical relevance and accuracy in a Swedish population is still unknown.MethodsThis retrospective single-center study included 74 patients with predominantly early-stage parkinsonism at first visit who had been examined by T
Introduction: After resuscitation from out of hospital cardiac arrest (OHCA), mechanical ventilation (MV) and respiratory management are fundamental to support patients in the intensive care unit (ICU) and to minimise secondary brain injury. Best practices for MV and association with clinical outcomes in patients with OHCA remain unclear. Methods and analysis: This protocol describes a pre-planned
This book explores the impact of migration on economic growth and entrepreneurship in Sweden. By looking at economic and migration trends over the last centuries, it examines the sectors, industries, and geographical locations where entrepreneurship has taken place, the economic and social impact of entrepreneurship, and the specifics of migrant entrepreneurship. Trends within Sweden are compared
Merouani and Perrin explore the representation of women inventors in historical records and discuss some of the potential biases that influence our current understanding of history. By examining a comprehensive database of nineteenth-century French patents as a case study, the authors find that women patented more frequently than contemporary biographical records suggest. Further, the authors illu
We study feedback-driven cold dark matter core creation in the edge suite of radiation-hydrodynamical dwarf galaxy simulations. Understanding this process is crucial when using observed dwarf galaxies to constrain the particle nature of dark matter. While previous studies have shown that the stellar mass to halo mass ratio (M∗/M200) determines the extent of core creation, we find that in low-mass
This study investigates coupled reduced-order modeling to develop efficient methods for analyzing the vibro-acoustic response of geometrically nonlinear thin structures interacting with acoustic fluids, such as gas or liquid. Projection-based model reduction is adopted for the structural and fluid domain. To consider geometric nonlinearity, the reduced nonlinear restoring forces of the elastic str
