Importance: Proposal of an innovative approach to clarify the mechanism through which poor cognitive performance in adolescence impacts risk for schizophrenia (SZ).Objective: To determine whether the developmental processes that predispose to SZ are better reflected by the observed cognitive performance in adolescence or the deviation of that performance from the individual's familial cognitive ap

Risk and vulnerability assessments (RVA) are vital components of the work conducted by public agencies at different levels, as part of the processes for governing and managing risks in the society. In Sweden, public agencies at all levels are required by legislation to perform risk and vulnerability assessments within their respective area of responsibility. The present paper presents a study of h

In this work, we present a novel self-aligned gate-last fabrication process for vertical nanowire metal-oxide-semiconductor field-effect transistors. The fabrication method allows for exposure dose-defined gate lengths and a local diameter reduction of the intrinsic channel segment, while maintaining thicker highly doped access regions. Using this process, InAs nanowire transistors combining good

Background: Many women of childbearing age are occupationally active, which leads to a large number of pregnancies potentially exposed to occupational exposures. Occupational noise has been identified as a risk factor for hearing impairment in adults. However, very few studies have assessed the effect of occupational noise on the fetus. Objectives: The aim of this study was to investigate whether

Objective To investigate the role of rheumatoid factor (RF) status and anti-citrullinated peptide antibody (ACPA) status as predictors of abatacept (ABA) effectiveness in patients with rheumatoid arthritis (RA). Methods We conducted a pooled analysis of data from 9 observational RA registries in Europe (ARTIS [Sweden], ATTRA [Czech Republic], BIOBADASER [Spain], DANBIO [Denmark], GISEA [Italy], NO

Distal radius fracture is an early indicator of osteoporosis, yet little is known about men with this fracture and osteoporosis prevalence. The purpose of this cross-sectional, controlled study was to evaluate bone mineral density (BMD) in men, from working age to the elderly, with distal radius fracture. Recruitment was as follows: men who fractured during 1999–2000 were evaluated retrospectively

Background: Despite the fact that heart failure and chronic obstructive pulmonary disease (COPD) often exist together and have serious clinical and economic implications, they have mostly been studied separately. Our aim was to study prevalence of coexisting heart failure and COPD in a Swedish population. A further goal was to describe levels of other comorbidity and investigate where the patients

Objective: To determine the reference interval of fetal scalp blood lactate during second stage of labor. Material: Two hundred and fifty-three women in first stage of labor with a reassuring CTG were asked for permission to sample fetal scalp blood during second stage. Results: In cases with reassuring CTG and five minute Apgar score ≥9, the mean lactate value (±2 SD) was 2.5 mmol/L (lower limit

A compact sample-scanning confocal optical microscope for detection of single impurities below the surface of a bulk crystal at cryogenic temperatures is described. The sample, lens, and scanners are mounted inside a helium bath cryostat and have a footprint of only 19 × 19 mm. Wide field imaging and confocal imaging using a Blu-ray lens immersed in liquid helium are demonstrated with excitation a

We show that approximating the Becker-Döring equations with a Langevin equation results in multiplicative noise, which in turn leads to a family of possible Fokker-Planck equations according to the Ito-Stratonovich dilemma. Using a simple and general model for the attachment and detachment rates, we find that the Ito choice approximates the nucleation rate best and also coincides with the Fokker-P

In this paper, an amplifier design using ballistic vertical InAs nanowire (NW) transistors is investigated, focusing on a basic common-source amplifier. The maximum power gain at 90 GHz is evaluated for different NW transistor architectures together with the power dissipation. The linearity of the amplifier is evaluated by estimating the IIP3 and 1-dB compression points. Furthermore, the impact of

Objective: The aim of this study was to assess the mortality in hip fracture patients with regard to use of fall-risk-increasing drugs (FRIDs), by comparing survival in exposed and nonexposed individuals. Design: This was a general population-based cohort study. Settings: Data on hip fracture patients were retrieved from three national databases. Participants: All hip fracture patients aged 60 yea

Background: Linkage analyses and association studies suggested that inherited genetic variations play a role in the development of differentiated thyroid carcinoma (DTC). Methods: We combined the results from a genome-wide association study (GWAS) performed by our group and frompublished studies onDTC. With a first approach, we evaluated whether a SNP published as associated with the risk of DTC c

Background: The etiology behind functional gastrointestinal symptoms is not clear. Only a few studies have examined how lifestyle factors affect these symptoms, especially in middle-aged or elder subjects. The aim of the present study was to describe the prevalence of functional gastrointestinal symptoms in a Swedish population-based cohort of middle-aged to elder subjects, and to examine associat

Objectives: To explore differences in body structure and function in systemic lupus erythematosus (SLE) patients and controls, with particular reference to joint hypermobility, and to evaluate the usefulness of the Brighton criteria for diagnosing joint hypermobility syndrome (JHS) in SLE. Method: Female SLE patients were, according to age group, consecutively invited to participate in the study.

Objectives Whether the increased risk of comorbidities, such as cardiovascular disease, in rheumatoid arthritis (RA) can be reverted by particular antirheumatic therapies, or response to these, is unclear but of critical clinical importance. We wanted to investigate whether response to tumour necrosis factor inhibitors (TNFi) translates into a reduced risk for acute coronary syndrome (ACS). Method

The electrical properties of ZrO2 and HfO2 gate dielectrics on n-InAs were evaluated. Particularly, an in situ surface treatment method including cyclic nitrogen plasma and trimethylaluminum pulses was used to improve the quality of the high-κ oxides. The quality of the InAs-oxide interface was evaluated with a full equivalent circuit model developed for narrow band gap metal-oxide-semiconductor (
