Popular Abstract in Swedish Syftet med den aktuella forskningen är att ge en bättre förståelse av förmaksflimmer, den vanligaste rytmrubbningen i hjärtat som drabbar så många som var tionde över 70 år. Mekanismerna för förmaksflimmer är långt ifrån kartlagda, vilket bland annat leder till att behandlingen är standardiserad istället för att den beror på de mekanismer som styr varje enskild patientsThis doctoral thesis is in the field of biomedical signal processing with focus on methods for the analysis of atrial fibrillation (AF). Paper I of the present thesis addresses the challenge of extracting spatial properties of AF from body surface signals. Different parameters are extracted to estimate the preferred direction of atrial activation and the complexity of the atrial activation pattern

The institutional landscape of the EU has been transformed through the establishment of agencies and changes brought by the Lisbon Treaty. This article seeks to contribute to our conceptual and empirical understanding of European agencies post-Lisbon. It maps the current European agencies according to timing of establishment, size, functions, governance structures and financial arrangements, and d

Scand J Caring Sci; 2009 Utilization of medical healthcare among people receiving long-term care at home or in special accommodation Aim: To investigate the utilization of medical healthcare, hospital care and outpatient care, during a 1-year period in relation to informal care, multimorbidity, functional status and health complaints and to long-term care at home or in special accommodation among

Cutaneous human papillomaviruses (HPV) are common in nonmelanoma skin cancers, benign skin lesions, and healthy skin. Increased seroprevalences for cutaneous HPV among nonmelanoma skin cancer patients have been described. To determine whether antibodies to cutaneous HPV are related to presence of the virus and/or to skin disease, we collected serum and biopsies from both lesions and healthy skin f

Multiple mechanisms contribute to tissue demise and functional recovery after stroke. We studied the involvement of macrophage migration inhibitory factor (MIF) in cell death and development of neurologic deficits after experimental stroke. Macrophage migration inhibitory factor is upregulated in the brain after cerebral ischemia, and disruption of the Mif gene in mice leads to a smaller infarct v

We aimed to estimate stratified absolute (cumulative) and relative (standardized incidence ratios; SIRs) risks of non-Hodgkin lymphoma (NHL) in relatives of NHL patients. A cohort of 169 830 first-degree relatives of 45 406 NHL patients who were diagnosed between 1955 and 2010 in five European countries was followed for cancer incidence. The lifetime (0-79 year) cumulative risk of NHL in siblings

Pancreatic cystic neoplasms are detected at an increasing frequency due to an increased use and quality of abdominal imaging. There are well known differential diagnostic difficulties concerning these lesions. The aim is to review current literature on the diagnostic options and the following treatment for cystic lesions in the pancreas focusing on serous cystadenomas, primary mucinous neoplasm of

ABSTRACT: BACKGROUND: Bone grafts are frequently used in orthopaedic surgery. Graft remodelling is advantageous but can occur too quickly, and premature bone resorption might lead to decreased mechanical integrity of the graft. Bisphosphonates delay osteoclastic bone resorption but may also impair formation of new bone. We hypothesize that these effects are dose dependent. In the present study

Neutral photodissociation of CO has been investigated using synchrotron light in the range 19-26 eV by observing dispersed fluorescence from excited neutral C atoms. Follow-up ab initio calculations support the observed neutral carbon excitation functions, which to a large extent are associated with the CO Rydberg series converging to the CO+ C and D states.

PURPOSE: Flexor tendons should be repaired with suture material strong enough to permit early motion and small enough for the resulting knot to allow unimpeded tendon glide and healing. This study sought to define differences in cross-sectional area and knotted tensile strength among Fiberwire, Prolene, and Ticron sutures. METHODS: Five strands, each of 3-0 and 4-0 Prolene, Ticron, and Fiberwire s

Formation and evolution of secondary organic aerosols (SOA) from biogenic VOCs influences the Earth's radiative balance. We have examined the photo-oxidation and aging of boreal terpene mixtures in the SAPHIR simulation chamber. Changes in thermal properties and chemical composition, deduced from mass spectrometric measurements, were providing information on the aging of biogenic SOA produced unde

The overall incidence rate of acute mesenteric ischemia between 1970 and 1982, diagnosed at either autopsy or operation, in the population of Malmö, Sweden was estimated at 12.9/100,000 person-years. Autopsy rate was 87%. Acute superior mesenteric artery (SMA) occlusion (embolus/thrombus ratio = 1.4), mesenteric venous thrombosis (MVT), and nonocclusive mesenteric ischemia (NOMI) were found in app

Concentrations of NO2 and O3 were measured inside and outside a dense broad-leaved forest canopy adjacent to a busy traffic route in the City of Gothenburg, Sweden, with duplicate passive diffusion samplers during six one-week periods starting well before leaf senescence and ending when leaves were largely senescent. Concentrations of NO2 were lower inside the forest canopy during all periods (rep

Avian time-activity budgets are known to be affected by many environmental factors. The aim of this study was to examine whether roosting times of common ravens Corvus corax are affected by inclement weather conditions in response to increased energy demands. The study was conducted at a communal roost of ravens in Thuringia, Germany, from August 2003 to January 2005. The number of roosting ravens

In this paper we consider a model for international tourism demand. The point of departure of the analysis is a utility function that is both dynamic and stochastic. In the model the stochastic component is interpreted as random changes in preferences for goods and services, while the dynamic component can be seen as either habit formation or as interdependent preferences. The resulting demand fun
