BACKGROUND: Reduced gait performance is common in persons with late effects of polio. OBJECTIVE: To identify predictors of change in gait performance over four years in persons with late effects of polio. METHODS: Gait performance was assessed annually in 51 ambulatory persons (mean age 64 years, SD 6) by the Timed "Up & Go" (TUG), Comfortable and Fast Gait Speed (CGS, FGS), and 6-Minute Walk

This thesis considers statistical methods for non-stationary signals, specifically stochastic modelling, inference on the model parameters and optimal spectral estimation. The models are based on Silverman’s definition of Locally Stationary Processes (LSPs). In all the contributions, an example of a biomedical application of the proposed method is provided. In the first two papers, the methods are

Introduction: Supraventricular ectopic complexes (SVEC) are known risk factors of recurrent atrial fibrillation (AF). However, the impact of SVEC in different age groups is unknown. We aimed to investigate the risk of AF recurrence with higher SVEC burden in patients ±. 57. years, respectively, after treatment with antiarrhythmic medication (AAD) or catheter ablation (CA). Methods: In total, 260 p

Purpose: Retinopathy of prematurity (ROP) causes childhood blindness globally in prematurely born infants. Although increased levels of oxygen supply lead to increased survival and reduced frequency of cerebral palsy, increased incidence of ROP is reported. Methods: With the help of a Swedish register for ROP, SWEDROP, national and regional incidences of ROP and frequencies of treatment were evalu

Objective: There is a paucity of data on heart transplantation (HTx) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC), and specific recommendations on indications for listing ARVC patients for HTx are lacking. In order to delineate features pertinent to HTx assessment, we explored the pre-HTx characteristics and clinical history in a cohort of ARVC patients who received hear

Doctoral education in medicine, engineering, technology and science (METS) is in many ways different from doctoral education in the humanities or social sciences. In the METS disciplines, typically, students and supervisors work and publish together within the supervisors’ research projects. The projects are usually financed by the supervisors’ research grants and their success, in terms of high q

Background and aims: The main aim of this study was to analyze and describe the clinical characteristics and shared personality traits in different impulsivity-compulsivity spectrum disorders: substance use disorders (SUD), gambling disorder (GD), and bulimia nervosa (BN). The specific aims were to compare personality differences among individuals with pure SUD, BN with and without SUD, and GD wit

Decision-making based on large amounts of data and different data sources constitutes a growing challenge for many actors in society. An increased flow of information from social media and open data sources means that decentralized decision-makers such as regions, municipalities and cities are forced to change, adapt, and modify their existing decision-making (Voight & Bright 2016). What is th

I nordsamisk er transitivitetsveksling alltid morfologisk markert – det vil si at to verb som sammen utgjør et transitivitetspar, aldri er morfologisk like. Det morfologiske forholdet mellom slike verb varierer derimot en hel del. Interessant nok viser det seg at de morfologiske mønstra vi kan observere i nordsamisketransitivitetspar, i noen tilfeller ser ut til å antyde en annen struktur enn den

Background: The pathological process in Alzheimer’s disease (AD) probably starts decades before the onset of symptoms and the clinical AD diagnosis. In patients with AD, the level of cerebrospinal fluid (CSF) amyloid-β1-42 (Aβ42) is usually lower, and the levels of total tau (T-tau) and phosphorylated tau (P-tau) higher than in healthy elderly people. However, the cutoffs differ between studies an
