BACKGROUND: In select patients with heart failure, cardiac resynchronization therapy (CRT) is the most common complementary treatment besides medical treatment. We aimed to assess the association between post CRT-implant changes in cardiovascular medication and cardiovascular mortality and heart failure hospitalization.METHODS: 211 patients on optimal medical therapy eligible for CRT were retrospe
Considering climate change and assessing its impacts is challenging due to dealing with large data sets and uncertainties. This paper discusses an approach for the impact assessment of climate change based on synthesizing weather data sets out of several climate scenarios, in a way to generalize the assessment despite of the existence of climate uncertainties. The is based on creating one-year wea
Early identification of patients who could benefit from early re-intervention after catheter ablation is highly warranted. Our aim was to investigate the association between post-procedural burden of supraventricular ectopic complexes (SVEC) and the risk of long-term atrial fibrillation (AF) recurrence. A total of 125 patients undergoing catheter ablation for AF were included. Patients underwent 7
In situ hybridization was used to study expression of mRNAs for members of the nerve growth factor (NGF) family in the rat brain after 2 and 10 min of forebrain ischemia and 1 and 30 min of insulin-induced hypoglycemic coma. Two hours after the ischemic insults, the level of brain-derived neurotrophic factor (BDNF) mRNA was markedly increased in the granule cells of the dentate gyrus, and at 24 h
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
During locomotion, neurons in motor cortex exhibit profound step-related frequency modulation. The source of this modulation is unclear. The aim of this study was to reveal the contribution of different limb controllers (locomotor mechanisms of individual limbs) to the periodic modulation of motor cortex neurons during locomotion. Experiments were conducted in chronically instrumented cats. The ac
Objectives: To investigate associations between autoimmune disorders and Parkinson disease (PD), and to study whether the risk is associated with follow-up time and age. Methods: Standardized incidence ratios (SIRs) were calculated for PD in patients with autoimmune disorders by comparing them to subjects without autoimmune disorders. Results: Among 310,522 patients with a total of 33 conditions o
In this licentiate thesis the implications of a deliberate use of logistics knowledge have been investigated by describing and analyzing the use of a supply chain management approach in the construction industry.
A five-step approach is used in the thesis. First, theoretical models are developed from the supply chain management literature. Two models are elaborated; One model identifying sup
Popular Abstract in Swedish Värmestrålning är högst relevant i förbränningsmiljöer. I dessa miljöer är förbränningsgaser och partiklar den huvudsakliga källan till värmestrålning. Förbränningsmiljön är komplex att beskriva. Analys av turbulenta flöden, kemiska reaktioner och transport av energi måste göras för att fullständigt beskriva miljön. Att kunna beskriva dessa fenomen är en viktig del i föThermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. This thesis has focused on studying thermal radiative property models of the participating media, gases and particles. Two specific combustion
Popular Abstract in Swedish I början av 1980-talet rökte ungefär var tredje gravid kvinna i Sverige. Detta innebar att rökning under graviditet var lika vanligt förekommande som rökning bland den vuxna befolkningen i övrigt. Sedan dess har rökningen bland gravida minskat markant och idag är det ungefär 10-12% som röker vid inskrivningen på mödravårdscentralen. Rökning under graviditet är en av deA smoking cessation program targeting pregnant women and their partners was monitored during 17 years and subjected to several substudies. All women in Blekinge, who gave birth in the months of September during the period 1984 to 2000, were asked to fill out a questionnaire, anonymously, about their smoking habits before and during pregnancy. During these years a long-term educational programme co
The purpose of this thesis is to contribute to understanding of the effect of organizational context on supply chain integration. One result is a context- based model that can provide support for practitioners regarding what level of integration to establish with suppliers and customers. Given the notion that most organizations are dependent on other organizations, it leads to a need for not only
A general mass calibration procedure of a PIXE set-up is described. As an example, the results of the calibration of the PIXE set-up in Lund are given. For the calibration commercially available standards were used. The parameters of a physical model were adjusted to fit a calibration curve. To decrease errors due to inhomogeneities of the standard foils, the average from four different pieces of
Background. Gynecologic examination is a common measure in reproductive health care. Many women experience the examination as a more or less negative event, with shortcomings in the examiner's behavior. The aim of the study was to describe, in terms of critical incidences, women's experiences concerning the personnel's behavior in the situation of gynecologic examination. Methods. The informants w
Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age- and/or sex-specific effects of genetic variants
1. Environmental factors fluctuate spatially and temporally, and organisms that can alter phenotype in response to these changes may increase their fitness. Zooplankton are known to be able to induce body pigmentation in response to ultraviolet radiation (UVR) and to reduce the pigmentation when exposed to fish predators. Hence, reduced pigmentation because of the presence of fish could potentiall
A short or otherwise suboptimal neck precludes the use of endovascular repair in 30% to 50% of patients with abdominal aortic aneurysms. Stent-graft fixation in an unsuitable neck carries the risk of technical failure owing to development of a proximal endoleak or stent-graft migration. Furthermore, in some patients, the neck dilates postoperatively. Endovascular healing with tissue incorporation
Aims: A study was undertaken to examine whether poor self-rated health (SRH) can independently predict all-cause mortality during 22-year follow-up in middle-aged men and women. Subjects and methods: Data are derived from a population-based study in Malmo¨ , Sweden. This included baseline laboratory testing and a self-administered questionnaire. The question on global SRH was answered by 15,590 me
Popular Abstract in Swedish Det huvudsakliga bidraget i denna avhandling är approximationsalgoritmer för flera problem inom beräkningsgeometri. Den underliggande strukturen för de flesta problemen är ett geometriskt nätverk. Ett geometriskt nätverk är, i sin mest abstrakta form, en mängd noder parvis kopplade med en kant, sådan att vikten på denna kant är lika med det Euklidiska (geometriska) avstThe main contribution of this thesis is approximation algorithms for several computational geometry problems. The underlying structure for most of the problems studied is a geometric network. A geometric network is, in its abstract form, a set of vertices, pairwise connected with an edge, such that the weight of this connecting edge is the Euclidean distance between the pair of points connected.
