This paper investigates the use of data-adaptive spectral estimation techniques for blood velocity estimation in medical ultrasound. Current commercial systems are based on the averaged periodogram, which requires a large observation window to give sufficient spectral resolution. Herein, we propose a novel data-adaptive method to form the blood velocity spectral estimate. The method is evaluated u
The purpose of risk management in the development of safety-critical software is to eliminate or reduce harmful behaviour. In health-care it is essential to manage risk related to software due to its increased use in medical devices and other computer systems. This paper presents some of the experiences gained from an ongoing case study at a large hospital in Sweden. The study focuses on identific
Supplemental Instruction/Peer Assisted Study Sessions (SI-PASS) is a peer learning program used worldwide to improve students’ learning and performance in challenging courses in higher education. A bonus effect of the program is the transferable skills that the student leaders may develop when facilitating the study sessions. These student leaders can potentially gain communication, group manageme
BackgroundThe quality and relevance of the information gathered is paramount when using the student voice to improve study programmes.Summary of workIn an on-going project we follow three cohorts of nursing students through their three-year programme. Methods used are two validated inventories (DREEM and CLES+T), written “free” comments, focus groups, semester meetings, and interviews with individ
The official notion of women in Burma is that they are equal to men but happy with their non- political domestic role in society. This notion undermines the work and struggle done by women in the oppositional movement. The purpose of this qualitative case study was to add to the understanding of how women participate in the Burmese ethnic and student oppositional movement. The study used feminist
Background: Laryngoscopy is a difficult skill to acquire and maintain and even more so by less frequent users. Numerous studies have compared limitations of direct laryngoscopic (DL) and video-assisted laryngoscopic (VL) techniques for endotracheal intubation in different scenarios, but individual retention over time of intubation skills with either technique has, to our knowledge, never been repo
Objective Surgical abortion in Lithuania is governed by a 1994 ministerial decree that made it legal for any woman 16 or older. This article seeks to determine the key demographic factors in Lithuanian attitudes towards medical abortion, which is currently not legal. Methods A random sample of the adult population was asked if they supported medical abortion. The dependent variable of attitude tow
Some elements have toxic effects on the human body and there is thus a need to control their levels in human organs and tissues. Moreover, it is important to increase our knowledge of relationships between observable toxic effects and element concentrations in man and his environment. Monitoring and basic occupational and environmental research rely on measurements directly in humans as well as sa
This thesis consists of two parts. The first part is devoted to automatic shape analysis and the second part is devoted to decision support systems in medical imaging. Shape models are widely used in segmentation and shape analysis. The thesis begins with a review of deformable models and the preliminaries of shape modelling. The criteria for Minimum Description Length (MDL) and a new optimization

Importance The clinical utility of the comprehensive laboratory and medical investigations currently recommended for children with pediatric acute-onset neuropsychiatric syndrome (PANS) remains unclear. Notably, comparisons with relevant psychiatric control patients without suspected immunologic pathogenesis are lacking. Objective To evaluate whether currently recommended laboratory investigations
