Effects of a school tobacco policy on student smoking and snus use

Objective: A school tobacco policy (STP) commonly is used to reduce smoking among adoles-cents, but the effectiveness of such programs is unclear. We evaluated the impact of an STP on tobacco use in 4 schools. Methods: The study included 4 intervention and 4 control schools, located in the inner city of Stockholm, Sweden. Schools self-selected for assignment to either an intervention program or a

On the heat transfer characteristics of a Lamilloy cooling structure with curvatures with different pin fins configurations

Purpose: The pin fin is applied into a Lamilloy cooling structure which is broadly used in the leading edge region of the modern gas turbine vane. The purpose of this paper is to investigate effects of the layout, diameter and shape of pin fins on the flow structure and heat transfer characteristics in a newly improved Lamilloy structure at the leading edge region of a turbine vane. Design/methodo

Phthalate levels in indoor dust and associations to croup in the SELMA study

Phthalates are ubiquitous indoor pollutants which have been associated with child airway disease although results are inconclusive. This study examined associations between phthalate levels in residential indoor dust and croup during infancy. Settled indoor dust was collected in 482 homes of 6-month-old infants in the Swedish Environmental Longitudinal, Mother and child, Asthma and allergy (SELMA)

Surgeon heterogeneity significantly affects functional and oncological outcomes after radical prostatectomy in the Swedish LAPPRO trial

Objectives: To evaluate how surgeon heterogeneity – the variation in outcomes between individual surgeons – influences functional and oncological outcomes after robot-assisted laparoscopic prostatectomy (RALP) and retropubic radical prostatectomy (RRP), and to assess whether surgeon heterogeneity affects the comparison between RALP and RRP. Patients and Methods: Laparoscopic Prostatectomy Robot Op

Background insect herbivory increases with local elevation but makes minor contribution to element cycling along natural gradients in the Subarctic

Herbivores can exert major controls over biogeochemical cycling. As invertebrates are highly sensitive to temperature shifts (ectothermal), the abundances of insects in high-latitude systems, where climate warming is rapid, is expected to increase. In subarctic mountain birch forests, research has focussed on geometrid moth outbreaks, while the contribution of background insect herbivory (BIH) to

Butterfly species’ responses to urbanization : differing effects of human population density and built-up area

Good knowledge on how increasing urbanization affects biodiversity is essential in order to preserve biodiversity in urban green spaces. We examined how urban development affects species richness and total abundance of butterflies as well as the occurrence and abundance of individual species within the Helsinki metropolitan area in Northern Europe. Repeated butterfly counts in 167 separate 1-km-lo

Family socio-economic status and childhood coeliac disease seem to be unrelated—A cross-sectional screening study

Aim: The aim of our study was to examine whether there is a difference in coeliac disease prevalence in regard to parents' education level and occupation, and whether this differs between screened and clinically diagnosed children at the age of 12 years. Methods: The study, Exploring the Iceberg of Celiacs in Sweden (ETICS), was a school-based screening study of 12-year-old children that was under

Antibiotic resistance and pathogenesis of Streptococci with focus on Group A Streptococci

Antibiotika-resistens utgör ett ökande hälsoproblem i världen och bakterier blir alltmer resistenta mot de antibiotika vi har att behandla med. Fler bakterier blir också resistenta mot mer än ett antibiotikum och behandling av infektioner med dessa typer av bakterier kompliceras av bristen på effektiva läkemedel vilket leder till ökade sjukvårdskostnader, längre vårdtider och en minskad chans att Multi-drug resistant (MDR) infections remain the leading cause of death worldwide. MDR infections caused by Streptococcus pneumoniae (Spn), Streptococcus pyogenes (GAS) and Streptococcus agalactiae (GBS) are considered global threats to human health due to increased spread of antibiotic resistance and limited treatment options. In this thesis, we present the human milk derived HAMLET (Human Alpha-

Upadacitinib tartrate in rheumatoid arthritis

In rheumatoid arthritis (RA) there is an unmet therapeutic need, as a substantial proportion of patients does not achieve low disease activity or remission despite the use of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and/or biological DMARDs (bDMARDs). The Janus kinase (JAK) inhibitors are the most recently added drug category in the therapeutic armamentarium in RA. U

Critical thinking and the humanities : A case study of conceptualizations and teaching practices at the Section for Cinema Studies at Stockholm University

The raison d’être of the humanities is widely held to reside in its unique ability to generate critical thinking and critical thinkers. But what is “critical thinking?” Is it a generalized mode of reasoning or a form of political critique? How does it relate to discipline-specific practices of scholarly pursuit? How does it relate to discourses of “post-truth” and “alternative facts”? How is it be

Framing the Feature Film : Multi-Reel Feature Film and American Film Culture in the 1910s

This dissertation addresses the breakthrough of the multi-reel feature film in the United States, and the significance of this process within the wider context of the American film industry and culture in the 1910s. The purpose is to provide a new, and more comprehensive analytical framing of the topic, and to enhance our understanding of how a new central commodity, i.e. the multi-reel feature fi
