Objective: Epidemiologic data indicate decreased risk for development, growth, and rupture of abdominal aortic aneurysm (AAA) among patients with type 2 diabetes mellitus (DM). We therefore evaluated mortality and cardiovascular morbidity after acute repair of AAA in diabetic and nondiabetic patients. Methods: In this nationwide observational cohort study of patients registered in the Swedish Vasc

By aiming to establish single-ended standoff combustion diagnostics, bidirectional lasing emissions of atomic hydrogen at 656 nm wavelength have been generated via two-photon resonant excitation by focusing 205 nm femtosecond laser pulses into a premixed CH4/O2 flame. The forward lasing strength is approximately one order of magnitude stronger than that of the backward one, due to the geometry of

The association between socioeconomic circumstances and incidence of chronic obstructive pulmonary disease (COPD) was investigated in an urban population in Sweden. The study included all 40–89 year-old inhabitants in Malmö, Sweden (N = 117,479) without previous hospitalization due to COPD, who were followed over 14 years for COPD related hospital admissions. The Malmö Preventive Project (MPP) co

The current work aims at investigating the detailed spatial structure of the thin plasma column of a gliding arc (GA) discharge extended in N2-CH4 gas mixtures, using visualization techniques. The GA discharge was operated at up to 5 atm in a high-pressure vessel with extensive optical access. The results show that the emission intensity from the plasma column increased tenfold with the addition o

A laser-based technique for recording absolute air-fuel ratio maps in a single-laser pulse in combustion devices, for instance, prior to ignition in internal combustion engines, is demonstrated. The method is based on an in situ pulse-to-pulse calibration of two-dimensional laser-induced fluorescence (LIF) images of relative fuel distributions by a point Raman measurement. A single excimer laser p

The scope of the compendium covers many parts of theemerging circular economy. We choose to place considerablefocus on some of the substances that we extract from theground – in particular raw materials and critical materials.We focus on circularity in these areas, because presentlywe use too much, too fast, and we are not re-using nearlyenough. In turn, this approach demands that we look atthe te

Objectives: To determine meniscal extrusion and cartilage coverage on magnetic resonance (MR) images and factors associated with these parameters in knees of middle-aged and elderly persons free from radiographic tibiofemoral osteoarthritis (OA). Methods: Seven hundred eighteen persons, free of radiographic tibiofemoral OA, aged 50–90 years from Framingham, MA, USA, were included. We measured meni

Traffic-related air pollution could be a danger to the health of children. Earlier studies have linked prenatal exposure to an increased risk of a range of diseases and negative health outcomes, including overweight and obesity. Presently, a knowledge gap exists in investigating the risk of overweight and obesity among children exposed to lower levels of air pollution in utero. This study aimed to

Introduction The provision of healthcare for patients with inflammatory arthritis occurs in the context of somewhat conflicting targets, values and drivers. Therefore, there is a need for introducing 'value-based healthcare' defined as the value of patient relevant health outcomes in relation to costs. This term is a central part of tomorrow's healthcare sector, especially for rheumatic diseases,

STUDY QUESTION: Is there an association between the number of oocytes retrieved for IVF, and perinatal and obstetric outcomes? SUMMARY ANSWER: No significant association was found between the number of oocytes retrieved and perinatal outcomes, while an association was found for placenta praevia and male gender. WHAT IS KNOWN ALREADY: Previous studies have shown that between 6 and 15 oocytes retrie

Infantile malignant osteopetrosis (IMO) is an autosomal recessive disorder characterized by nonfunctional osteoclasts. Approximately 50% of the patients have mutations in the TCIRG1 gene, encoding for a subunit of the osteoclast proton pump. Gene therapy represents a potential alternative treatment to allogeneic stem cell transplantation for IMO. The oc/oc mouse is a model of IMO characterized by

PURPOSE: Advanced glycation end products (AGEs) can be formed in foods by the reaction of reducing sugars with proteins, and have been shown to induce insulin resistance and obesity in experimental studies. We examined the association between dietary AGEs intake and changes in body weight in adults over an average of 5 years of follow-up.METHODS: A total of 255,170 participants aged 25-70 years we

Bakgrund Med en snabbt växande äldre populationsgrupp kommer även andelen med kognitiva störningar, som demens, att växa. Det är således nödvändigt med forskning på kognition och åldrande. Denna avhandling, genom fyra delarbeten, redogör för testledareffekter vid kognitionsmätningar och hur yngre födelsekohorter (generationer) presterar bättre än äldre på kognitionstester. Den kommer även förklaraGiven a growing population of older adults and the common occurrence of natural as well as pathological cognitive decline, i.e. dementia, there is a need to better understand how to accurately measure and classify level of cognitive functioning. Both using multiple test administrators to collect cognitive data and what year the participant is born (birth cohort effects) can influence participants’

The need to integrate climate change adaptation (CCA) considerations into disaster risk management (DRM) systems is widely recognised. However, successful integration, and thus the implementation of integrated planning measures, is difficult in practice. To understand and reduce the problems encountered, it is important to investigate systemic challenges. These challenges are rooted in the interac

Ultrasound optical tomography (UOT) is an imaging technique based on the acousto-optic effect that can perform optical imaging with ultrasound resolution inside turbid media, and is thus interesting for biomedical applications, e.g. for assessing tissue blood oxygenation. In this paper, we present near background free measurements of UOT signal strengths using slow light filter signal detection. W

Genome-wide association studies have identified breast cancer risk variants in over 150 genomic regions, but the mechanisms underlying risk remain largely unknown. These regions were explored by combining association analysis with in silico genomic feature annotations. We defined 205 independent risk-associated signals with the set of credible causal variants in each one. In parallel, we used a Ba

Arthroscopic partial meniscectomy (APM) may lead to changes in underlying trabecular bone (TB) structure potentially promoting the development of knee joint osteoarthritis. Our aim was to investigate if there are early changes occurring in tibial subchondral TB texture in the leg undergoing medial APM compared with the unoperated non-injured contra-lateral leg. The bone texture was measured as the
