Objective: Testicular torsion (TT) is a medical emergency, difficult to identify solely through clinical evaluation. This study aims to develop an assessment algorithm with a safe lower threshold for complementary ultrasound. Material and methods: Males between 1 and 30 years of age assessed for suspected TT during the years 2019 – 2023 were retrospectively included. Clinical assessments were cond

Avian genomes are typically stable, yet instances of chromosome fissions, fusions and translocations are known across various lineages. For example, multiple sex chromosome translocations have been described in the superfamily Sylvioidea. In this study, we examine the sex chromosomes in two Sylvioidea families, Nicatoridae and Cisticolidae, using whole-genome data. We found sex-linkage of chromoso

The purpose of this study is to explore how adolescents in self-contained classrooms or schools for students with autism or ADHD, with no prior involvement in criminality, perceive and interpret different forms of early offending behavior through fictional case stories. The study specifically aims to examine their ability to discern what constitutes offending behavior, based on the double empathy

Objectives: – To quantify the risk of incident psychiatric morbidity after community-acquired sepsis and assess whether new chronic diseases mediate the association. Design: – Nationwide, population-based matched register cohort; hazards estimated with weighted Cox regression. Setting: – Sweden, linking the National Quality Sepsis Registry, National Patient Register, Prescribed Drug Register, and

Quantification using the Centiloid (CL) scale has become a valuable information to consider when interpreting amyloid-PET images and is now implemented in several software packages. This work aims to assess the comparability of CL from [18F]flutemetamol scans derived using several research and commercial quantification pipelines. Methods: This analysis relies on three datasets: a test-retest cohor

This study investigates the impact of a 10-week Arts on Prescription (AoP) program in Denmark designed for young adults aged 18–30 who were disengaged from education and unemployed. Eighteen participants took part in four semi-structured focus group interviews, and four completed a survey; most reported experiences of anxiety, depression, and stress, with some describing chronic pain, ADHD, or aut

Background: Fine-needle aspiration biopsy (FNAB) is the preferred first-line diagnostic tool for evaluating lymphadenopathy due to its minimally invasive nature and cost-effectiveness. However, cytopathological interpretation of lymph node FNAB remains challenging because of the wide morphological spectrum of lymphoid lesions. The World Health Organization (WHO) Reporting System for Lymph Nodes, S

Background Drug use disorder (DUD) clusters in families due partly to shared environment, including sibling influences. Low academic achievement (AA) in adolescence increases DUD risk. This study examined whether low AA in an older sibling causally increases DUD risk in younger siblings. Methods We studied all Swedish full sibling pairs (n = 309,666) born 1972–1985 and ≤ 5 years apart. Older sibli

Both high-mountain rivers and wet-based mountain glaciers are considered effective erosion agents. They acted alternatively or simultaneously during the late Quaternary in the Tatra Mountains (West Carpathians) thus producing a vast amount of clastic material that was subject to deposition, reworking and transportation downstream. A small fraction of that amount of the material is still preserved

Seagrass meadows are recognized for their coastal protection services in terms of reducing the wave runup level and limiting coastal erosion. This study aims to quantify these services for a dense seagrass meadow located in a non-tidal, fetch-limited sea. A year-long field campaign was conducted to collect data on wave statistics along the cross-shore direction of the seagrass meadow, bathymetry,

BACKGROUND: Alterations in ribosomal DNA copy number (rDNA-CN) and global DNA methylation have been associated with genomic instability and various diseases. However, their relevance in myocardial infarction (MI) has not been fully investigated.METHODS: We measured rDNA-CN and global DNA methylation in blood samples from MI patients ( n  = 100) and healthy controls ( n  = 109) using Droplet Digit

Human calcitonin (hCT) is a peptide hormone with therapeutic potential for bone-related disorders, yet its clinical application is hindered by a strong propensity to form amyloid fibrils. Strategies that effectively suppress hCT aggregation are therefore essential for enabling its reintroduction into pharmaceutical development. In our previous work, heme emerged as a potent inhibitor of hCT fibril

We present the structural and functional characterization of a single-stranded DNA-binding protein (SSB-M5) identified from a hot spring metagenome in Vatnajökull National Park, Iceland. This small protein (136 aa; 15,695 Da) shares 100% amino acid sequence identity with two previously uncharacterized SSBs from hyperthermophilic Fervidobacterium species. Functional complementation assay demonstrat

Interactions between amyloidogenic proteins are emerging as critical drivers of neurodegenerative diseases. Among others, in Alzheimer’s disease (AD) and severe forms of chronic traumatic encephalopathy (CTE), codeposition of tau and amyloid-β (Aβ) leads to worsening of clinical outcomes and disease progression. Despite the importance of such heterotypic interactions, the underlying molecular mech

BACKGROUND: Long COVID has emerged as a global health challenge, with increasing evidence of cardiovascular sequelae. Most previous studies have focused on hospitalised cohorts, whereas cardiovascular risk in community-managed long COVID cases remains less explored. We aimed to investigate the incidence of major cardiovascular events in individuals with long COVID compared to those without long CO
