New temporary internal introducer shunt for brain perfusion during total endovascular arch replacement with in situ fenestration technique.

Complete endovascular arch replacement by in situ fenestration technique requires maintenance of cerebral perfusion during the fenestration procedure by an extracorporeal femoral-carotid bypass. The bypass has the disadvantages of being invasive, requiring a pump and shunting blood extracorporeally. This report describes bench testing and an in vivo experimental animal setup with an endovascular,

Are Treatment Satisfaction, Quality of Life, and Self-assessed Disease Severity Relevant Parameters for Patient Registries? Experiences from Finnish and Swedish Patients with Psoriasis.

Patient registries often lack indicators of the disease as experienced by patients, e.g. treatment satisfaction and self-assessed disease severity. There is scarce information about the relationship between these assessments and currently existing instruments used in treatment evaluation. Our objective was to explore the importance of these indicators among patients with psoriasis in Finland and S

Psychometric testing of the brief screening version of Multidimensional Pain Inventory (Swedish version).

BACKGROUND: The brief screening version of the Multidimensional Pain inventory (MPI) is a shorter version of the West Haven-Yale Multidimensional Pain Inventory that measures pain in a multidimensional way and is theoretically linked to a cognitive-behavioural perspective on chronic pain. OBJECTIVES: The aim of this study was to psychometrically evaluate the 'brief screening version' of the Multid

An explicit link between Gaussian fields and Gaussian Markov random fields; The SPDE approach

Continuously indexed Gaussian fields (GFs) is the most important ingredient in spatial statistical modelling and geo-statistics. The specification through the covariance function gives an intuitive interpretation of its properties. On the computational side, GFs are hampered with the "big-n" problem, since the cost of factorising dense matrices is cubic in the dimension. Although the computational

A preliminary regional division for efficient biodiversity preservation based on disturbance regime, forest history and tree species distribution: the southern Swedish example.

We propose a method for dividing large regions into biogeographical sub-regions based mainly on natural disturbance regime, forest history and potential tree species distribution. This subdivision could be used as a guide when designing conservational strategies and management plans for landscapes and protected areas. At present, conservational strategies and management of valuable areas on the on

Initial clinical experience with a new biointegrative cement for vertebroplasty in osteoporotic vertebral fractures.

Summary: Polymethylmethacrylate, as a widely used material for vertebroplasty, has several drawbacks such as heat development and high allergenic potential. In order to avoid these drawbacks ceramic cement materials have been developed. The purpose of this study was to evaluate a new biointegrative material for vertebroplasty in osteoporotic vertebral fractures regarding pain relief, safety aspect
