It is presently unclear whether free serum 25 hydroxyvitamin D (S 25(OH)D) better reflects bone health than total S 25(OH)D. We have previously shown that summer total S 25(OH)D values are more useful to predict bone mineral density (BMD) than winter values. Our objective was therefore to compare the relative importance of free and total S 25(OH)D for BMD by season. BMD was measured by dual energy

BackgroundThe impact of season when determining a serum 25-hydroxyvitamin D (S-25OHD) cut-off level for optimal bone health is unknown.ObjectiveTo investigate the relative importance of S-25OHD for bone mineral density (BMD) by season.MethodsA subcohort of 5002 Swedish women (mean age 68 years), randomly selected from a large population-based longitudinal cohort study with repeat dietary and lifes

This article provides an overview of the role mediation analyses play in causal inferencemethodology and in the estimation of the effect an exposure may have on an outcome throughdirect and indirect pathways. We discuss traditional approaches to mediation and where thesemay lead to bias, before discussing more advanced methods that can be used to overcome thesebiases in situations with single and

Eighteen lichen species, one lichenicolous and two allied fungi are reported for the first time for Latvia (Europe). Bryoria smithii, Heterodermia speciosa, Phaeophyscia pusilloides and Ramalina europaea are new records for the Baltic countries. Comments on habitats and substrates of new records are provided.

PurposeDual design for additive manufacturing (DfAM) takes into account both the opportunities and constraints of AM simultaneously, which research shows is more effective than considering them separately. Unlike existing reviews, this paper aims to map DfAM research within the engineering design process, focusing solely on studies adopting dual DfAM. Additionally, it aims to suggest future resear

Obsessive-compulsive disorder (OCD) and anxiety disorders are early-onset mental disorders characterized by selective attention and strong emotional reactions. Attentional bias has been proposed to play a role in the development, onset, and maintenance of the disorders, but few studies have included youth with mental disorders, and no study has included more than one clinical group, making it uncl

Background: Recent studies indicate the need to examine how the gut microbiota–brain axis is implicated in pain, sensory reactivity and gastro-intestinal symptoms in autism spectrum disorder (ASD), but no scale exists that assesses all these constructs simultaneously. Methods: We created a pool of 100 items based on the real-world experience of autistic people, and a multidisciplinary team and sta

The analysis of interconnected systems is a large and growing field, with successful applications in a wide range of natural and synthesized systems. Biomolecular networks, power grids and human social dynamics have all been the subject of study through the lens of network dynamics, with impressive results. The work presented in this thesis takes the form of four research papers all focusing in di

IntroductionCardiac arrest (CA) survivors often face significant health challenges, including insomnia, which can adversely affect their health-related quality of life. The Minimal Insomnia Symptom Scale (MISS) is a brief, self-reported instrument designed to screen for insomnia. This study aimed to identify the measurement properties of the MISS in CA survivors and to explore a relevant cut-off sIntroductionCardiac arrest (CA) survivors often face significant health challenges, including insomnia, which can adversely affect their health-related quality of life.
