Diffusion of macromolecules in extracellular matrix mimetic hydrogels - effect of size and charge.

Subcutaneous (SC) injection is the primary alternative to oral administration for therapeutic proteins and peptides. However, bioavailability and absorption rate are often variable and difficult to predict. Therefore, there is a need for new biorelevant and predictive SC in vitro methods.

Metabolic Profiling Reveals a Glycolytic Shift and an IRG1/Itaconate/NF2L2 Axis Regulating Neurotoxic Oxidative Stress in Inflammatory Microglia.

Polar metabolic profiling, as well as bioenergetic assays, were used to characterize microglial responses to lipopolysaccharide, which induces a pro-inflammatory state, and interleukin-4, which is associated with an anti-inflammatory phenotype. BV2 microglial cells and primary microglia were used for these investigations. Results revealed that lipopolysaccharide-treated microglia exhibited an increased aerobic glycolytic activity measured by extracellular flux analysis, accompanied by increased levels of endogenous itaconate, a metabolite produced by the IRG1 enzyme.

Patterns of immunity changes predict response to stereotactic ablative radiotherapy in early non-small-cell lung cancer.

Background: Stereotactic Ablative Radiotherapy (SABR) for early-stage non-small cell lung cancer (NSCLC) can stimulate an immune response against cancer. We evaluated changes in peripheral lymphocyte subpopulations and cytokines levels after SABR in patients with early-stage NSCLC. We examined how these changes relate to overall survival (OS) and disease-free survival (DFS).

Implementing Federated Analysis using DataSHIELD in the DREAM TO TREAT Atopic Dermatitis Registries Collaboration.

Many new biologic treatments and small molecule agents are emerging and being approved for treating atopic dermatitis (AD). Robust evidence, based on large sample sizes from real-world clinical settings, are needed to investigate the use of these new therapies, However, adequate sample sizes of patient data are difficult to obtain within one country alone, requiring international collaboration and data aggregation. To address this need for cooperative research, we investigated the feasibility for an international collaboration of registries to gather data from real-world clinical settings on patients' use of new systemic treatments for AD by creating a federated network between national registries that enables an analysis environment protecting privacy of information and ensuring compliance with General Data Protection Regulation.

Spinal fractures in patients with versus without ankylosing spinal disorders: a nationwide propensity score-matched study on survival and health-related quality of life.

Objective: The evidence on ankylosing spinal disorders (ASDs), including ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH), in the context of spinal fracture stems from studies with relatively small sample sizes. There are no studies addressing the patient-reported outcome measures (PROMs) and health-related quality of life (HRQOL) outcomes associated with spinal fracture in this population. The aim of this study was to investigate differences in complications, mortality, PROMs, and HRQOL in patients with and without ASD who had been treated for spinal fracture.

How do I implement a whole blood program with low blood wastage?

Background: The use of low-titer O whole blood (LTOWB) is requested in the treatment of major bleeding, initially used in military medicine but now increasingly utilized in civilian prehospital care. The advantage is the administration of a balanced transfusion, red blood cells, coagulation factors, and platelets, in one bag. The challenges are the availability of LTOWB and difficulties in predicting the need in major bleeding, leading to the risk of wastage.

Genetically determined body mass index is associated with diffuse large B-cell lymphoma in polygenic and Mendelian randomization analyses.

Obesity has been associated with non-Hodgkin lymphoma (NHL), but the evidence is inconclusive. We examined the association between genetically determined adiposity and four common NHL subtypes: diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, chronic lymphocytic leukemia, and marginal zone lymphoma, using eight genome-wide association studies of European ancestry (N = 10,629 cases, 9505 controls) and constructing polygenic scores for body mass index (BMI), waist-to-hip ratio (WHR), and waist-to-hip ratio adjusted for BMI (WHRadjBMI). Higher genetically determined BMI was associated with an increased risk of DLBCL [odds ratio (OR) per standard deviation (SD) = 1.

Assessment of stigma in Spanish people with chronic pain using the 8-item Stigma Scale for Chronic Illnesses (SSCI-8).

Stigma is common in people with chronic pain. At present, however, the measurement of stigma in Spanish-speaking individuals remains a challenge due to a lack of validated measures in Spanish. The present study examines the psychometric properties of the Spanish version of the Stigma Scale for Chronic Illnesses 8-item version (SSCI-8) in people with chronic pain, focusing on dimensionality, factorial invariance, reliability (internal consistency and test-retest), and construct validity.

Stability After Legal Gender Change Among Adults With Gender Dysphoria.

Importance: The number of people seeking treatment for gender dysphoria (GD) has risen in recent decades, yet data remain limited for understanding cases of detransition (ie, the reversal of social, medical, or legal transition). Legal gender change in national registers poses an opportunity to examine legal gender reversals, which may reflect an aspect of the detransition process, while also informing an understanding of the stability after a legal gender change.

Objective: To determine the probability of obtaining a legal gender change and its stability over time among people diagnosed with GD in Sweden during a 10-year study period.

Comparison of liver histology and fibrosis-4 scoring as tools for evaluating healthcare resource utilization and costs in patients with MASLD: a Swedish cohort study.

Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with substantial clinical and economic burden. Fibrosis detection is key to disease management, but biopsy-defined staging is invasive, expensive, and associated with complications. We evaluated healthcare resource utilization (HCRU) and costs by disease stage using biopsy-defined staging and fibrosis-4 (FIB-4; a simple, well-validated, non-invasive tool for assessing fibrosis severity), and compared their utility for predicting long-term outcomes in MASLD.

Interfacial degradation of PEO-based polymer electrolytes on the NMC cathode and CEI components prediction.

All-solid-state Li-metal batteries using solid polymer electrolytes (SPEs) in combination with high-voltage cathodes such as lithium nickel manganese cobalt oxide (NMC) promise enhanced battery safety, energy density, and flexibility. However, understanding the oxidative decomposition of SPEs on the cathode surfaces and characterizing the resulting cathode-electrolyte interphase (CEI) remain challenging both experimentally and computationally. This study introduces a new computational protocol based on ab initio molecular dynamics for simulating the decomposition of PEO:LiTFSI SPE on the NMC-811 cathode surface using a combined electron- and Li+-removal simulation approach.

The assessment and management of patients with type 2 myocardial infarction: an international Delphi study.

Aims: Type 2 myocardial infarction due to myocardial oxygen supply-demand imbalance is associated with poor outcomes. There are no guidelines to inform care for these patients. The consensus on the assessment and management of type 2 myocardial infarction is gained.

Functional Relevance of CASP16 Nucleic Acid Predictions as Evaluated by Structure Providers.

Accurate biomolecular structure prediction enables the prediction of mutational effects, the speculation of function based on predicted structural homology, the analysis of ligand binding modes, experimental model building, and many other applications. Such algorithms to predict essential functional and structural features remain out of reach for biomolecular complexes containing nucleic acids. Here, we report a quantitative and qualitative evaluation of nucleic acid structures for the CASP16 blind prediction challenge by 12 of the experimental groups who provided nucleic acid targets.

Ocean surface waves impact on global air-sea CO flux.

Unlabelled: Ocean surface gravity waves facilitate gas exchanges primarily in two ways: (1) the formation of bubbles during wave breaking increases the surface area available for gas exchange, promoting CO transfer, and (2) wave-current interaction processes alter the sea surface partial pressure of CO and gas solubility, consequently affecting the CO flux. This study tests these influences using a global ocean-ice-biogeochemistry model under preindustrial conditions. The simulation results indicate that both wave-current interaction processes and the sea-state-dependent gas transfer scheme-which explicitly accounts for bubble-mediated gas transfer velocity-influence the air-sea CO flux, with substantial spatial and seasonal variations.

Genetic Adaptation to Brackish Water and Spawning Season in European Cisco.

How species adapt to diverse environmental conditions is essential for understanding evolution and the maintenance of biodiversity. The European cisco (Coregonus albula) is a salmonid that occurs in both fresh and brackish water, and this together with the presence of sympatric spring- and autumn-spawning lacustrine populations provides an opportunity for studying the genetics of adaptation in relation to salinity and timing of reproduction. Here, we present a high-quality reference genome of the European cisco based on PacBio HiFi long read sequencing and HiC-directed scaffolding.

Background: Drug-coated devices are widely used to reduce restenosis after lower limb revascularisation in patients with peripheral artery disease, but their effect on patient-centred outcomes remains unclear. We assessed the effect of paclitaxel-coated devices on clinically important outcomes in patients with intermittent claudication undergoing infrainguinal endovascular revascularisation.

Methods: The Swedish Drug-Elution Trial in Peripheral Arterial Disease 2 (SWEDEPAD 2) was a pragmatic, nationwide, multicentre, participant-masked, registry-based, randomised controlled trial conducted at 22 Swedish vascular centres.

Computationally Efficient DFT-Based Sampling of Ion Diffusion in Crystalline Solids.

We present a method for large-scale DFT-based screening of ion diffusion in crystalline solids. This is accomplished by extending the Ionic TuTraSt method to sample the potential energy surface by using single-point DFT calculations. To drastically reduce the number of single-point DFT calculations, symmetry, interpolation, and exclusion of high-energy regions are employed.

Changes in Documentation After Implementing Open Notes in Mental Health Care: Pre-Post Mixed Methods Study.

Background: The practice of providing patients with digital access to clinical narrative documentation by health care professionals (HCPs) is known as open notes. In mental health care, this innovation has the potential to increase transparency and foster greater trust in the treatment process. While open notes may improve the quality of care and patient engagement, some HCPs are concerned that they may change the nature of clinical documentation and compromise its quality.
