Comparison of Dialysate Calcium Concentrations and Arterial Stiffness in Dialysis Patients: A Network Meta-analysis

Abstract Background Chronic kidney disease often requires hemodialysis, which increases cardiovascular risk, partly because of arterial stiffness. This can be influenced by dialysate calcium concentrations, which affect mineral balance and vascular health. However, there is contr...

Short-term knowledge gains and learner satisfaction after a basic radiology course for family medicine residents in a 3-dimensional virtual environment: a multi-cohort pretest–posttest study in Spain

Purpose: This study aimed to evaluate a structured basic radiology course for Family Medicine residents delivered in a 3-dimensional (3D) virtual environment (Second Life). We hypothesized that participation would be associated with higher post-course knowledge test scores and hi...

Decoupling geometry and topography reveals contrasting ecomorphological signals in carnivoran carnassial teeth

Abstract The lower carnassial tooth (m1) is a key innovation underlying the ecological diversification of Carnivora. However, their exceptionally diverse phenotypes result from both functional adaptation and phylogenetic inertia which challenges ecomorphological inferences. We in...

Rural tourism and inflation: changes in behaviour, intention to travel and spending on leisure trips

The recent surge in inflation has had a profound impact on the tourism sector. This study investigates how inflation has altered the behaviour and spending patterns of rural tourists. It is essential to ascertain any changes that have occurred in the behaviour of rural tourists a...

The rise of carnivoran mammals in Europe through the lens of body mass

Carnivoran mammals (cats, dogs, bears, seals, etc.) and their kin radiated during the Palaeogene, among other carnivorous clades (hyaenodonts, mesonychians, and oxyaenodonts). This radiation has often been framed as a competition ultimately won by carnivorans, but the data suppor...

Towards maintainable AI-driven network anomaly and threat detection: a comparative analysis of datasets, preprocessing techniques, and model trade-offs

Abstract As the integration of Artificial Intelligence into network intrusion detection systems matures, a critical gap remains in the rigorous empirical benchmarking of datasets, preprocessing techniques, and model effectiveness. This article presents a comparative experimental...

Variables Associated with Prescription Opioid Misuse in Individuals with Chronic Noncancer Pain

OBJECTIVES: Current research highlights the importance of assessing the risk of opioid misuse in people with chronic noncancer pain (CNCP) before initiating treatment with these medications. Existing instruments to assess this risk demonstrate limited predictive capacity and lack...

Proteomic profiling of root microsomal membrane fractions reveals distinct RBOHC- and RBOHF-associated responses to cadmium in Arabidopsis

Cadmium (Cd) is a toxic heavy metal for plants, and although its mechanisms of toxicity are well characterized, the regulatory networks underlying plant responses remain incompletely understood. This study investigated membrane-associated molecular responses linked to RBOHC and R...

When technical standards fail. Questionnaire wording and the comparability of PISA truancy data

Abstract This paper presents a case study of how an undetected wording change in the OECD’s Programme for International Student Assessment (PISA) may have led to erroneous conclusions. We focus on a survey question intended to measure student truancy across countries and over tim...
