Background: Long-term oxygen therapy (LTOT) increases life expectancy in patients with COPD and severe hypoxemia. Smoking is the main cause of burn injury during LTOT. Policy regarding smoking while on LTOT varies between countries. In this study, we compare the incidence of burn injury that required contact with a health care specialist, between Sweden (a country with a strict policy regarding sm

Background: Elite athletes, independent of sport, have increased risk of developing asthma, but little is known about sex difference among adolescent athletes. Objective: To investigate and compare sex-related differences according to symptoms and treatment of asthma, allergy, and health among elite athletes and a reference group. Methods: Adolescent elite swimmers (n = 101), tennis players (n = 8

This paper investigates whether the Notional Defined Contribution (NDC) scheme prolongs working life. The evidence from the 1994 Swedish pension reform shows a gender and socio-economic gradient in the labor supply responses to phasing in NDC. While the reform exerted a large and significant positive effect on the average retirement age among highly educated and skilled, it had little or negative

Although zinc-blende (ZB) and wurtzite (WZ) structures differ only in the atomic stacking sequence, mixing of crystal phases can strongly affect the electronic properties, a problem particularly common to bottom up-grown nanostructures. A lack of understanding of the nature of electronic transport at crystal phase junctions thus severely limits our ability to develop functional nanowire devices. I

Quantum chemical calculations for two TiO2 nanoparticle cluster models (rutile–(TiO2)n with n = 20, and anatase–(TiO2)n with n = 92), selected to represent different nanoparticle size regimes, are used to elucidate structural influences on the electronic properties. Structural and electronic properties were obtained using a variety of computational methods and structure optimisation schemes, inclu

BACKGROUND: Patients with back and neck pain are often seen in primary care and it is important to provide them with tailored interventions based on risk stratification/triage. The STarT Back Screening Tool (SBT) is a widely used screening questionnaire which has not yet been validated for a population with back and/or neck pain with short duration. Our aim was to compare the concurrent validity o

Prostate-specific antigen (PSA) levels have been used for detection and surveillance of prostate cancer (PCa). However, factors other than PCa - such as genetics - can impact PSA. Here we present findings from a genome-wide association study (GWAS) of PSA in 28,503 Kaiser Permanente whites and 17,428 men from replication cohorts. We detect 40 genome-wide significant (P<5 × 10-8) single-nucleotide

Aim: Information about the prevalence of special diets in preschool children is limited. The aim of this study was to measure the prevalence of all special diets among preschool children in a Swedish municipality. Methods: This was a population-based cross-sectional survey of all 3276 preschool children aged one to five years in the municipality of Karlskrona, Sweden. The questionnaire assessed th

Nanowires can act as efficient light absorbers where waveguide modes are resonant to specific wavelengths. This resonant wavelength can easily be tuned by the nanowire dimensions, but the absorption of infrared radiation requires diameters of hundreds of nm, which is difficult to achieve using epitaxial growth. Here, we demonstrate that infrared absorption in InAsSb nanowires with the diameters of

Objective: No large-scale nationwide study has determined the risk of ocular manifestations in patients with giant cell arteritis (GCA). The aim was to study the incidence and risk factors of ocular manifestations in patients with GCA in Sweden. Method: A national cohort was created by linking Swedish nationwide registers. GCA patients were identified from the Swedish Hospital Inpatient and Outpat

We here investigate the growth mechanism of Sn-seeded GaSb nanowires and demonstrate how the seed particle and its dynamics at the growth interface of the nanowire determine the polarity, as well as the formation of structural defects. We use aberration-corrected scanning transmission electron microscopy imaging methodologies to study the interrelationship between the structural properties, i.e. p

A general scaling formalism for nonlinear light-matter interactions in gases is presented and experimentally verified. The formalism enables to conveniently extrapolate nonlinear phenomena, such as filamentation or high-order harmonic generation, to new laser parameters.

Neurodevelopmental disorders (Attention-Deficit/Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), tic disorder, intellectual disability (ID)), in prison populations have received increased attention but the focus has generally been on one single condition leaving out the global picture. This study assessed the prevalence and overlap of neurodevelopmental disorders (NDD) in a consecuti

Background: Whether personality factors and depressive traits affect patients' utilization of health care following an acute myocardial infarction is relatively unknown. The aim of this study was to examine whether hospital-based health care utilization after a myocardial infarction was correlated with patients' personality factors and depressive symptoms. Methods: We studied 366 myocardial infarc

III-V ternary nanowires are interesting due to the possibility of modulating their physical and material properties by tuning their material composition. Amongst them InAs1-xSb x nanowires are good candidates for applications such as Infrared detectors. However, this material has not been grown directly from substrates, in a large range of material compositions. Since the properties of ternaries a

Contemporary disaster risk management requires the exchange and integration of risk information across societal sectors and administrative borders. However, differences in how risk is described can be an obstacle to making sense of the material. This paper focuses on the challenge of aggregating risk assessments from multiple stakeholders and aims to establish the characteristics of risk descripti

B cell receptor signaling and downstream NF-κB activity are crucial for the maturation and functionality of all major B cell subsets, yet the molecular players in these signaling events are not fully understood. Here we use several genetically modified mouse models to demonstrate that expression of the multifunctional BRCT (BRCA1 C-terminal) domain-containing PTIP (Pax transactivation domain-inter

Growth of III-V semiconductor nanowires is generally assisted by a liquid particle in order to get a highly anisotropic crystallization. The thermodynamic stability of the particle is therefore of importance for control and understanding of the nanowire growth process. In this report we explore the particle stability by manipulating its properties, specifically its surface tension and volume, by a
