Background: Women are disproportionately affected by migraine, representing up to 75% of all migraine cases. This discrepancy has been proposed to be influenced by differences in hormone levels between the sexes. One such hormone is progesterone. Calcitonin gene-related peptide (CGRP) system is an important factor in migraine pathophysiology and could be influenced by circulating hormones. The pur

Objective: The aim of this study is to define and assess Ideal Outcome in the national or multicenter registries of North America, Germany, the Netherlands, and Sweden. Background: Assessing outcomes after pancreatoduodenectomy among centers and countries requires a broad evaluation that cannot be captured by a single parameter. Previously, 2 composite outcome measures (textbook outcome and optima

Aims/hypothesis: A better understanding of the mechanisms underlying an elevated infection risk in individuals with type 2 diabetes is needed to guide risk stratification and prevention. We investigated the risk of infection in subgroups of individuals with type 2 diabetes according to indices of insulin sensitivity and beta cell function. Methods: We classified 7265 individuals with recently diag

UNLABELLED: Colon cancer screening occurs at younger ages than osteoporosis screening. Bone density measurements using virtual colonoscopy performed for colon cancer screening can provide an early warning sign of patients at potential risk for osteoporosis-related fractures. Earlier identification may improve treatment and potentially fracture prevention.INTRODUCTION: Opportunistic osteoporosis sc

Popular Abstract in Swedish Polymerer är samlingsnamnet på långa molekylkedjor. Runt omkring oss i vårt dagliga liv är vi omgärdade av polymerer så som plaster, lim, fibrer och proteiner. Utvecklingen av många högteknologiska produkter är starkt beroende av polymera material. Grundläggande kunskaper om dem och deras egenskaper är därför viktigt. I ett batteri kan många fördelar erhållas då den koThere is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. Consequently, these electrolytes should ideally posse

The aim of the thesis work is the further development of practical engine simulation tools based on Stochastic Reactor Models, SRMs. Novel and efficient implementations were made of a variety of SRMs adapted to different engine types. The models in question are the HCCI-SRM, the TwoZone SI-SRM and the DI-SRM. The specific models developed were incorporated into two different interfaces: DARS-ESSA,

Hur ska vi analysera elberoenden i framtiden? Hur analyseras elberoendet i samhället och vad borde ingå i en sådan analys? Detta har Kicki Rönnåker och Sofia Wennerbeck försökt ta reda på i en studie där vetenskapliga metoder jämförts med praktiska tillvägagångssätt för analyser av el. Den skillnad som hittades fick ligga till grund för ett antal förbättringsförslag som förhoppningsvis kommer kuIn Sweden, risk- and vulnerability assessments, including dependency analyses, are required by law for public actors who are of vital societal functions or critical infrastructure. However, there is a lack of guidance regarding how to perform this kind of analysis. Electrical power is one of the strongest dependencies of our society today. Thus, it is interesting to examine how the dependency of e
