Expression of hormone receptors in oropharyngeal squamous cell carcinoma
Hormone receptors play an important role in many types of cancers. Alongside factors associated with human papillomavirus (HPV) infection, hormonal receptors may impact the tumorigenesis of oropharyngeal cancer. This study consists of 199 consecutive oropharyngeal squamous cell carcinoma (OPSCC) patients diagnosed and treated with a curative intent. We examined androgen (AR), estrogen (ER; both alpha and beta), and progesterone receptor (PR) expressions using immunohistochemistry comparing tumor and patient characteristics. AR was expressed in 16%, PR in 27% and ER-beta in 63% of the tumors. HPV- and p16-positive tumors expressed more AR and less PR than their negative counterparts. High PR expression was associated with poor disease-specific and locoregional recurrence-free survival. AR, PR, and ER-beta are expressed in OPSCC, and AR and PR expressions are associated with HPV and p16 status. Furthermore, PR appears to have prognostic significance. This may allow us to investigate the role of anti-hormone receptors in the treatment of OPSCC.Peer reviewe

Creating an Audio Story with Interactive Binaural Rendering in Virtual Reality
The process of listening to an audiobook is usually a rather passive act that does not require an active interaction. If spatial interaction is incorporated into a storytelling scenario, can open. Possibilities of a novel experience which allows an active participation might affect the user-experience. The aim of this paper is to create a portable prototype system based on an embedded hardware platform, allowing listeners to get immersed in an interactive audio storytelling experience enhanced by dynamic binaural audio rendering. For the evaluation of the experience, a short story based on the horror narrative of Stephen King's Strawberry Springs is adapted and designed in virtual environments. A comparison among three different listening experiences, namely, (i) monophonic (traditional audio story), (ii) static binaural rendering (state-of-the-art audio story), and (iii) our prototype, is conducted. We discuss the quality of the experience based on usability testing, physiological data, emotional assessments, and questionnaires for immersion and spatial presence. Results identify a clear trend for an increase in immersion with our prototype compared to traditional audiobooks, showing also an emphasis on story-specific emotions, i.e., terror and fear
Setting the scene: controversies on trends in mental health among adolescents in the Nordic countries
At present there are different positions regarding trends in adolescent mental health. Can we trust trend data on the mental health among adolescents in the Nordic countries? Some question the trustworthiness of adolescent self-reports, which describe ordinary daily hassles as health complaints, which cannot be interpreted as signs of mental disorders. In addition, today there is a more open climate for talking about mental issues, which can lead to an overestimation of the prevalence of mental disorders.Statistics on mental health services statistics report increased psychopharmaceutic prescriptions as well as consumption of professional care. Such data argues for increased governmental investment in adolescent mental health services. Is this pattern due to increased availability of mental health services and/or increased prevalence of mental health problems in the adolescent population?A concern is that data availability influences policymaking and allocation of resources. If there is an emphasis on self-reported data from adolescents that may an increased risk of medicalization of young people's dealing with their daily lives. If on the other hand the reported problems among young people is disregarded, this would be against the UN Child Convention.The survey data has important qualities especially if the data is analysed and reported properly. The validation of survey measure has been done both regarding psychometric quality and content validity. Advanced analysis of the data can draw a more nuanced picture. Moreover, some screening instruments have been developed as a first step towards making diagnosis. Instead the HBSC surveys ask boys and girls about their health and well-being, social environment and health behaviours. HBSC uses findings at national and international levels to gain new insights into young people's health and wellbeing, understand the social determinants of health, and inform policy and practice to improve young people's lives
On the time trends among school-aged children in the Nordic countries
Long-term trends in mental health of school-aged children can be analysed in the HBSC study. In Sweden the proportion of the children that report at least two weekly health complaints during the last six months has increased from the first data collection 1985/1985 to the latest 2017/2018 among all age groups for both girls and boys. Among the 11-year-old it reached 41 % among girls and 30 % boys, and among 15-year-old girls 62 % and boys 35 %. Can we trust this?The prevalence of two or more weekly health complaints showed large differences by country over time and especially in 2014, when Iceland and Sweden showed an almost 10%-point larger prevalence of multiple weekly symptoms (about 35%) than Denmark, Finland and Norway (about 25%). Norway was the only country to show a decline during 2002-2014.The prevalence of sleep difficulties has increased over the 12-year period in Denmark, Iceland, and Finland. In Sweden the prevalence fell from 26% to 21% from 2002 to 2006 but rose by 10% points from 2010 to 2014. Only Norway showed a positive development over the 12-year period; the prevalence declined in 2014 to 17% the lowest prevalence of sleep difficulties in any of the five Nordic countries.The trend of excellent self-rated health for Nordic adolescents indicates a small overall improvement between 2002 and 2006 but a stable trend in the following periods up until 2014. Finland and especially Sweden shows a decline in the prevalence of students having an excellent self-rated health. The only country to show a positive development in the prevalence of students having excellent self-rated health from 2002 to 2014, is Norway. The overall prevalence of adolescents having high life satisfaction has declined in most of the Nordic countries examined
