Background: Chronic Pseudomonas aeruginosa (PA) infection causes increased morbidity and mortality in cystic fibrosis (CF). This study aimed to answer the following questions: Does the prevalence of chronic infection with PA differ between the CF centres in Scandinavia? Which differences exist concerning segregation and treatment of PA? Methods: 989 patients (86%) from all eight CF-centres in Scan

Chemokines are chemotactic cytokines that orchestrate leukocyte trafficking in tissues, thus, playing an important role in regulation of immunological processes. The aim of this study was to investigate the association of human papillomavirus (HPV) infection and cervical cancer with two DNA polymorphisms of the chemokine receptors CCR5-Delta 32 and CCR2-64L The study material consisted of 50 cervi

ln this article, we analyze fertility control in a rural population characterized by natural fertility, using survival analysis on a longitudinal data set at the individual level combined with food prices. Landless and semilandless families responded strongly to short-term economic stress stemming from changes in prices. The fertility response, both to moderate and large changes in food prices, wa

Physical activity is regarded as an important component of a healthy lifestyle. Several social and environmental factors have systematically emerged as barriers to low leisure time physical activity (LTPA), for example, lack of money, low social support due to lack of supportive family or friends, and living in high crime rate areas. Low LTPA has been found to be strongly associated with low socio

Objectives. The first aim was to describe some aspects of each of the three perspectives in the triangular meeting between immigrant patients, interpreters and GPs, including their experiences, reflections and interactions during the consultation in primary health care. The second aim was to analyse patients' satisfaction with the consultation; whether satisfaction is influenced by respect for pat

Some of the main bottlenecks for the development and commercialization of photovoltaic/thermal hybrids are the lack of an internationally recognized standard testing procedure as well as a method to compare different hybrids with each other and with conventional alternatives. A complete methodology to characterize, simulate and evaluate concentrating photovoltaic/thermal hybrids has been proposed

In a longstanding debate among economic historians about the role of the peasants and the manors in the agrarian transformation, a variety of qualitative and quantitative indicators have been used, but no one has until now been able to compare the actual production outcomes. In this paper, we investigate the land productivity development for manorial demesnes and peasant farmers, respectively, ove

The Siljan impact structure is the largest known impact structure in Europe, the result of a Late Devonian meteorite impact (380.9 +/- 4.6 Ma). It is outlined mainly by a ring of lakes and Palaeozoic sedimentary rocks of Ordovician to Devonian age. The Palaeozoic successions are generally poorly exposed, but often well preserved with clear stratigraphy. At some locations they are strongly tectonis
