- Periodontal pathogens, including Polphyromonas gingivalis, can form biofilms in dental pockets and cause inflammation, which is one of the underlying mechanisms involved in the development of periodontal disease, ultimately leading to tooth loss. Although P. gingivalis is protected in the biofilm, it can still cause damage and modulate inflammatory responses from the host, through secretion of microvesicles containing proteinases. The aim of this study was to evaluate the role of cysteine proteinases in P. gingivalis colony growth and development, and subsequent immunomodulatory effects on human gingival fibroblast. By comparing the wild type W50 with its gingipain deficient strains we show that cysteine proteinases are required by P. gingivalis to form morphologically normal colonies. The lysine-specific proteinase (Kgp), but not arginine-specific proteinases (Rgps), was associated with immunomodulation. P. gingivalis with Kgp affected the viability of gingival fibroblasts and modulated host inflammatory responses, including induction of TGF-beta 1 and suppression of CXCL8 and IL-6 accumulation. These results suggest that secreted products from P. gingivalis, including proteinases, are able to cause damage and significantly modulate the levels of inflammatory mediators, independent of a physical host-bacterial interaction. This study provides new insight of the pathogenesis of P. gingivalis and suggests gingipains as targets for diagnosis and treatment of periodontitis.

Tid att följa upp : Digital tidmätning i svensk hemtjänst
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Digitala tidmätningssystem används i svensk hemtjänst för att mäta och följa upp hemtjänstbesökens längd och innehåll. Systemen samlar in data i realtid och om alla besök. I detta avseende är digital tidmätning ett kraftfullt verktyg som kan förväntas ge bättre förutsättningar för mål-och resultatstyrning än analoga metoder. Samtidigt innebär tidmätningen risker för arbetsmiljön då den kan uppfattas som detaljstyrande och stressande. I denna rapport presenterar vi resultaten från en enkät som skickades ut till alla kommuner om deras användande av tidmätningssystem i hemtjänsten. 123 kommuner besvarade enkäten och 94 av dessa angav att de mäter tidsanvändningen med hjälp av digitala system. I denna rapport presenterar och diskuterar vi resultaten från denna enkät.

The relation between office type and workplace conflict : A gender and noise perspective
- 2015

Ingår i: Journal of Environmental Psychology. - : Elsevier BV. - 0272-4944 .- 1522-9610. ; 42, s. 161-171

Tidskriftsartikel (refereegranskat)abstract
- This exploratory study aimed to investigate the impact of the office design on workplace conflicts, with a special attention to noise in the office. A gender perspective was applied. The sample consisted of 5229 employees from the Swedish Longitudinal Occupational Survey of Health 2010 (SLOSH), working in different office types. In the multivariate analysis office type was used as the explanatory variable with adjustments for age, supervisory position and labour market sector. Analysis stratified for gender was used. Among women a significant impact of office type per se on workplace conflicts was found, but not among men. For women several office types differed significantly from the cell-office with regard to prevalence of conflicts during the past two years, but for men only the combi-office differed from the cell-office. Noise had an impact on workplace conflicts, but is not the only explanatory factor since the effect of office type remained also after adjustment for noise in multivariate analyses. Other environmental factors inherent in the office type might thus explain the occurrence of conflicts.

“Let’s Keep it Informal, Guys” : a Study of the Effects of Teacher Communicative Strategies on Student Activity and Collaborative Learning in Internet-based English Courses
- 2008

Ingår i: Tidskrift för lärarutbildning och forskning. - Umeå : The faculty board for teacher education. - 1404-7659. ; 15:2, s. 36-58

Tidskriftsartikel (refereegranskat)abstract
- The paper explores the quantity and quality of communication produced by teachers in Internet courses of academic English, particularly during the initial stages of course activity. The courses are entirely conducted in virtual learning environments without physical meetings, and are part of the Bachelor programme (A–C level) of English at Mid Sweden University. The pedagogic design of the courses is based on collaborative learning, which presupposes a communicative environment with positive interdependence and interaction, where knowledge is shared by students questioning and challenging each other. Consequently, the teacher’s role in setting communicative norms which encourage an environment of high acceptance, where students feel that they can express their opinions freely, is of utmost importance. The results suggest that there are two important factors that affect student activity in the initial stages of an online course: how much the teacher communicates with the class and the manner in which he or she does so.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Vi vet idag inte tillräckligt om sömnvanor, medievanor och dess relation till andra livsstilsfaktorer såsom fysisk aktivitet och övervikt hos barn och ungdomar. Med förändringarna i samhället förändras också våra barns och ungdomars sömn- och livstilsvanor. Detta är frågor som många ställer till elevhälsan. I detta kapitel kommer resultat från studier om sömn, medievanor och livsstil att beskrivas. Vi kommer även att sätta ljuset på frågor som är angelägna att studera vidare.

Tidskriftsartikel (refereegranskat)abstract
- ObjectivesInsufficient sleep is a public health problem that impacts the mental and physical health of children and adolescents. Complaints of insomnia are particularly pervasive among adolescents. This longitudinal study investigates factors that contribute to teen insomnia symptoms. DesignFive-year prospective follow-up study. SettingSchool-based. ParticipantsA total of 522 children (49.8% girls) aged 9.4 +/- 1.3 years at baseline; 14.4 +/- 0.7 years at follow-up. MeasurementsThe dependent variable of insomnia symptoms at follow-up was assessed with the Minimal Insomnia Symptom Scale-Revised. The independent variables at baseline were the perceived family financial situation, tiredness at school, problems waking up, short sleep duration, sleeping difficulties, having a bedroom Television (TV), and time spent with a TV/computer. Multivariate binary logistic regression analyses were used to examine whether the independent variables at baseline predicted insomnia symptoms at follow-up. ResultsPerceived quite bad/very bad family financial situation (OR 3.1; CI 1.4-6.7) and short sleep duration (<10 h) (OR 2.3; CI 1.0-5.3) among girls at baseline were associated with insomnia symptoms at follow-up. Having problems waking up among boys at baseline was associated with insomnia symptoms at follow-up (OR 4.9; CI 1.6-14.4). ConclusionShort sleep duration, problems waking up, and perceived bad family financial situation during childhood were linked with adolescent insomnia symptoms. The sex-based differences in these associations warrant further investigation to effectively mitigate adolescent insomnia.
