OBJECTIVES: Mental ill-health has become a large health problem and it is important for caregivers to provide effective treatment alternatives. REGASSA is a randomized controlled study performed in primary care to study the effects of 12 weeks of Internet-based cognitive behaviour therapy (ICBT) and physical exercise (PE) compared with treatment as usual (TAU) in patients with mild-to-moderate men

Background: The primary aim of this paper is to describe the design of a project evaluating the effects of using a research-based strategy for managing housing adaptations (HAs). The evaluation targets clients' perspectives in terms of activity, participation, usability, fear of falling, fall incidence, use of mobility devices, and health-related quality of life, and determines the societal effect

Here we present results from a field experiment in an Arctic wetland situated in Zackenberg, NE Greenland. During one growing season we investigated how dominance of the sedge Eriophorum scheuchzeri affected the below-ground concentrations of low molecular weight carbon compounds (LMWOC) and the fluxes of CO2 and CH4 in comparison to dominance of other sedges (Carex stans and Dupontia psilosantha)

Introduction: Career termination, an inevitable step in every athlete’s career, has received increased attention within sport psychological research. A career termination that results in psychological problems is of special concern for sport federations, organizations and clubs. Research has shown that it is crucial to consider an athlete’s the reason for career termination. There is evidence that

Clinical and experimental results have revealed a fundamental role of calcitonin gene-related peptide (CGRP) in primary headaches. CGRP is widely expressed in neurons both in the central nervous system (CNS) and in peripheral sensory nerves. In the CNS there is a wide distribution of CGRP-containing neurons with the highest levels seen in striatum, amygdale and cerebellum. Moreover, in acute attac

Popular Abstract in Swedish Ordet "fängelse" ger mångfaldiga och motstridiga associationer; till höga murar och gallerförsedda fönster, till inspärrning, straff och farliga brottslingar men också till förtryck, utstötthet och trasiga människor. De svenska fängelserna växte fram under 1800-talet och var en del i en internationell trend. Fängelset framställdes som ett stort humanitärt och straffrättThe general aim of the thesis is to study 19th century Swedish prisons from the point of view of the surrounding discourse and also as a social system. The prison phenomenon grew out of the meeting between prisons as a discourse-produced norm system and the social practice consisting of the reality as experienced by the prisoners and the prison staff. The growth and development of the Swedish pris

Popular Abstract in Swedish Men älskar du honom? Så frågar en ung flicka på 1820-talet sin syster Henrietta som just skall gifta sig. Nej det gör Henrietta inte men hon böjer sig för den krassa verkligheten, behovet att bli försörjd. Den stillsamma frågan anger något som kan tolkas som en tyst revolution: övergången från en äldre syn på äktenskapet som ett ekonomiskt kontrakt till en uppfattning aThe main theme of this dissertation is the question of how young women in the early middle class handled the new demands for marriage based on love instead of on judgements of moral, economy and status. Another theme is the education of these middle class girls around 1800 and the question how this new education interacted with the new demands for love marriage. The German social historian Ulrike

The aim of this Master's thesis is to study how DIK (Documentation, Information and Culture), the major trade union for Swedish librarians, work with the status and professionalization of the occupation. The status is, as we see it, low and depending on several factors. They are among others: the knowledge base, how extended the research base is and the domination of women within the professio

Background: Pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension are chronic diseases with a severe symptom burden. Common symptoms are dyspnoea at light activity and general fatigue that limits daily activities. Respiratory modulation by device-guided breathing decreased symptoms in patients with heart failure. The aim of this pilot study was to investigate if respira

Research and PhDs are relatively rare in family medicine and primary care. To promote research, regular one-year research courses for primary care professionals with a focus on clinical epidemiology were started. This study explores the academic outcomes of the first four cohorts of research courses and surveys the participants' perspectives on the research course. An electronic survey was sent to

One feature of climate change is the increasing heat exposure in many workplaces where efficient cooling systems cannot be applied. Excessive heat exposure is a particular problem for working people because of the internal heat production when muscle work is carried out. The physiological basis for severe heat stroke, other clinical effects, and heat exhaustion is well known. One feature of this h

Background: Pediatric lead (Pb) exposure impacts cognitive function and behavior and co-exposure to manganese (Mn) may enhance neurotoxicity. Objectives: To assess cognitive and behavioral function in adolescents with environmental exposure to Pb and Mn. Methods: In this cross sectional study, cognitive function and behavior were examined in healthy adolescents with environmental exposure to metal

Popular Abstract in Swedish Gående som mellanmänsklig handling Traska, spatsera, flanera, power-gå, ila, dra fötterna efter sig, ta en stärkande promenad eller bara vandra bort i tankarna för en kort stund. Att gå är en komplex handling som omfattar allt från upplevelsen av marken som vi går på till människorna vi möter. Både när vi är ute och går själva eller tillsammans med andra så förhåller vThere is a lack of attention toward the diversity in experiences of architecture that are expressed through walking. Through the application of autoethnography and critical perspectives of queer and feminist theory, this dissertation develops a method for investigating experiences of architecture in regard to the activity of walking. In addition, this thesis addresses the influence of form, materi

Cholecystokinin (CCK) is a hormone with well-known secretory and trophic effects on the pancreas. This also is true for epidermal growth factor (EGF), which acts in a paracrine and autocrine way. The aim was to study the influence of CCK on cell proliferation in rat pancreas with special reference to the expression of EGF, the EGF receptor, and phosphorylated tyrosine. Twenty-four male Sprague-Daw

Objective: It is important to understand levels and social inequalities in childhood overweight within and between countries. This study examined prevalence and social inequality in adolescent overweight in 35 countries, and associations with macroeconomic factors. Design: International cross-sectional survey in national samples of schools. Subjects: A total of 11-, 13- and 15-year-olds from 35 co

Reduction of trans-[Pt(CN)(4)Cl-2](2-) by [Pt(NH3)(4)](2+) and [Pt(en)(2)](2+) was studied at 25 degrees C in the range 0 less than or equal to [Cl-] less than or equal to 0.4 M by use of stopped-flow spectrophotometry. The stoichiometry [Pt(IV)]:[Pt(II)] is 1:1. Rapid-scan spectra show clear-cut isosbestic points, indicating that no reaction intermediates are accumulated to a significant amount.

Background: Diffusion magnetic resonance imaging (MRI) is the current-state-of-the-art technique to clinically investigate acute (0-24 h) ischemic stroke tissue. However, reduced apparent diffusion coefficient (ADC)-considered a marker of tissue damage-was observed to reverse spontaneously during the subacute stroke phase (24-72 h) which means that low ADC cannot be used to reflect the damaged tis

Aim: To study (a) the covariation between patient reported experience measures (PREMs) and registered process measures of access and continuity when ranking providers in a primary care setting, and (b) whether registered process measures or PREMs provided more or less information about potential linkages between levels of access and continuity and explaining variables. Background: Access and conti

Introduction: Recent haemophilia treatment advances include new recombinant FVIII (rFVIII) products with improved pharmacokinetic (PK) properties that aim to reduce the burden of prophylaxis. These treatments are commonly referred to as extended half-life rFVIII products (EHL rFVIII). There is no uniform definition of what constitutes an EHL rFVIII. Such a definition would help physicians, patient
