- Glioma is the most common type of adult brain tumor and glioblastoma, its most aggressive form, has a dismal prognosis. Receptor tyrosine kinases such as the epidermal growth factor receptor (EGFR, ERBB2, ERBB3, ERBB4) family, and the vascular endothelial growth factor receptor (VEGFR), play a central role in tumor progression. We investigated the genetic variants of EGFR, ERBB2, VEGFR and their ligands, EGF and VEGF on glioma and glioblastoma risk. In addition, we evaluated the association of genetic variants of a newly discovered family of genes known to interact with EGFR: LRIG2 and LRIG3 with glioma and glioblastoma risk. Methods. We analyzed 191 tag single nucleotide polymorphisms (SNPs) capturing all common genetic variation of EGF, EGFR, ERBB2, LRIG2, LRIG3, VEGF and VEGFR2 genes. Material from four case-control studies with 725 glioma patients (329 of who were glioblastoma patients) and their 1 610 controls was used. Haplotype analyses were conducted using SAS/Genetics software. Results. Fourteen of the SNPs were significantly associated with glioma risk at p< 0.05, and 17 of the SNPs were significantly associated with glioblastoma risk at p< 0.05. In addition, we found that one EGFR haplotype was related to increased glioblastoma risk at p=0.009, Odds Ratio [OR] = 1.67 (95% confidence interval (CI): 1.14, 2.45). The Bonferroni correction made all p-values non-significant. One SNP, rs4947986 next to the intron/exon boundary of exon 7 in EGFR, was validated in an independent data set of 713 glioblastoma and 2 236 controls, [OR] = 1.42 (95% CI: 1.06,1.91). Discussion. Previous studies show that regulation of the EGFR pathway plays a role in glioma progression but the present study is the first to find that certain genotypes of the EGFR gene may be related to glioblastoma risk. Further studies are required to reinvestigate these findings and evaluate the functional significance.

- The human telomerase reverse transcriptase (hTERT) gene is upregulated in a majority of malignant tumours. A variable tandem repeat, MNS16A, has been reported to be of functional significance for hTERT expression. Published data on the clinical relevance of MNS16A variants in brain tumours have been contradictory. The present population-based study in the Nordic countries and the United Kingdom evaluated brain-tumour risk and survival in relation to MNS16A minisatellite variants in 648 glioma cases, 473 meningioma cases and 1,359 age, sex and geographically matched controls. By PCR-based genotyping all study subjects with fragments of 240 or 271 bp were judged as having short (S) alleles and subjects with 299 or 331 bp fragments as having long (L) alleles. Relative risk of glioma or meningioma was estimated with logistic regression adjusting for age, sex and country. Overall survival was analysed using Kaplan-Meier estimates and equality of survival distributions using the log-rank test and Cox proportional hazard ratios. The MNS16A genotype was not associated with risk of occurrence of glioma, glioblastoma (GBM) or meningioma. For GBM there were median survivals of 15.3, 11.0 and 10.7 months for the LL, LS and SS genotypes, respectively; the hazard ratio for having the LS genotype compared with the LL was significantly increased HR 2.44 (1.56-3.82) and having the SS genotype versus the LL was nonsignificantly increased HR 1.46 (0.81-2.61). When comparing the LL versus having one of the potentially functional variants LS and SS, the HR was 2.10 (1.41-3.1). However, functionality was not supported as there was no trend towards increasing HR with number of S alleles. Collected data from our and previous studies regarding both risk and survival for the MNS16A genotypes are contradictory and warrant further investigations.

- The purpose of this study was to explore the variation in DNA repair genes in adults with WHO grade II and III gliomas and their relationship to patient survival. We analysed a total of 1,458 tagging single-nucleotide polymorphisms (SNPs) that were selected to cover DNA repair genes, in 81 grade II and grade III gliomas samples, collected in Sweden and Denmark. The statistically significant genetic variants from the first dataset (P < 0.05) were taken forward for confirmation in a second dataset of 72 grade II and III gliomas from northern UK. In this dataset, eight gene variants mapping to five different DNA repair genes (ATM, NEIL1, NEIL2, ERCC6 and RPA4) which were associated with survival. Finally, these eight genetic variants were adjusted for treatment, malignancy grade, patient age and gender, leaving one variant, rs4253079, mapped to ERCC6, with a significant association to survival (OR 0.184, 95% CI 0.054-0.63, P = 0.007). We suggest a possible novel association between rs4253079 and survival in this group of patients with low-grade and anaplastic gliomas that needs confirmation in larger datasets.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Under flera decennier har forskare inom naturvetenskapernas didaktik undersökt hur aktuella samhällsfrågor kan få betydelse i naturvetenskapsundervisningen. Flera olika inriktningar har vuxit fram, där undervisningens syfte och genomförande skiljer sig åt. Det handlar om allt från att samhällsfrågorna endast bidrar med ett sammanhang, där elever relativt förenklat tillämpar naturvetenskapliga kunskaper, till att undervisningen syftar till att lägga en grund för global handlingskompetens. I den här artikeln beskriver vi några olika inriktningar med exempel på hur de kan omsättas i undervisningspraktiken. Därmed vill vi synliggöra överväganden man som lärare kan behöva göra när man vill använda samhällsfrågor i sin nv-undervisning.

- The wireless motility-recording capsule, "SmartPill", is an ingested one-time use electronic capsule that measures gastrointestinal luminal pressure, pH and temperature along the whole gastrointestinal tract. The pH profile and the pressure patterns define the time at which the capsule moves from the stomach to the duodenum and from the ileum to the caecum, whereas changes in temperature define the times of ingestion and expulsion. The recordings from the wireless motility capsule are sent from a radio transmitter in the capsule to a receiver carried around the waist. Wireless motility recordings have several advantages over imaging and manometry that have been used previously. Primarily the simplicity by which motility recordings are done, as well as the tolerability for the patient and limited need of assistance are valuable aspects. The wireless motility capsule provides standardized measures of transit with relevant normal values for the clinical work-up of patients with motility disturbances.

- Aim: To describe telenurses’ experiences of difficult calls.Design: A qualitative approach with a descriptive design was used to gain a deeper understanding of the telenurses’ experiences.Methods: The data were collected in spring 2017 through semi-structured interviews with 19 telenurses at call centres and primary healthcare centres and were analysed with qualitative content analysis.Results: Becoming emotionally concerned is central to the telenurse’s experiences of difficult calls. Difficult calls are accompanied by feelings such as inadequacy, uncertainty and anxiety, which can be described as emotional tension. Emotional tension refers to situations when the caller’s expressed emotions were conveyed to the telenurses and altered their state of mind. The telenurses stated that difficult calls that cause them to become anxious remain in their thoughts and go through their minds repeatedly, making a deep impression.

- Context:Obesity and insulin resistance are risk factors for cancer development. The IRS1 rs2943641 genetic variant has been widely associated with insulin resistance.Objective:The aim of the study was to examine whether the IRS1 rs2943641 associates with cancer incidence in obese individuals.Design, Setting and Patients:The IRS1 rs2943641 was genotyped in participants from the Swedish Obese Subjects (SOS) study, an intervention trial on the effect of bariatric surgery on mortality and morbidity compared with usual care and in the population-based Malmö Diet and Cancer (MDC) cohort. In both studies, the median follow-up for cancer incidence was about 15 years.Intervention and Main Outcome Measure:Cancer incidence was assessed in both the SOS and the MDC cohorts through national and local registers.Results:The IRS1 T allele was associated with lower insulin resistance in both the SOS and the MDC studies. A lower cancer incidence was found in T allele carriers from the SOS control group (hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.62-0.96; P = .021) and was restricted to morbidly obese individuals (HR 0.67, 95% CI 0.50-0.91; P = .011). No evidence of such association was detected in the surgery group (interaction P = .005). In the MDC cohort, a nonsignificant tendency for lower cancer incidence in T allele carriers was observed only in morbidly obese individuals. A meta-analysis of morbidly obese individuals (body mass index > 40 kg/m(2)) from the two cohorts strengthened the evidence for the association (HR 0.66, 95% CI 0.50-0.87; P = .004).Conclusions:Our results suggest that the T allele of rs2943641 near IRS1 may associate with lower cancer incidence in morbidly obese individuals.

- During the COVID-19 pandemic, the Internet has been a major source of information for people to keep updated with news and guidelines. However, concerns have been raised about the ‘infodemic’, which includes the overabundance of online information and the spread of misleading information. Adequate eHealth literacy skills among world citizens have therefore been emphasized as vital during the pandemic. Persons with type 2 diabetes have been at increased risk of severe outcomes of COVID-19 disease. This study aimed to explore online COVID-19 information acquisition experiences among persons with type 2 diabetes and varying eHealth literacy. Fifty-eight participants filled out the eHealth Literacy Scale (eHEALS), along with a qualitative questionnaire with free-text questions. Additionally, 10 participants were interviewed. Thematic analysis was applied to identify patterns in participants’ experiences. Two domains were identified: perceived challenges with online information about COVID-19, and coping strategies to manage challenges. The perceived challenges were: being exposed to information overload, dealing with conflicting information, and being strongly emotionally affected. The related coping strategies were: protecting oneself, trusting authorities, taking command, and using common sense. These strategies often involved triangulation of the information obtained, including participants consulting their common sense, various sources, or family and friends. This paper highlights the crucial role of authorities in delivering online information, that according to health literacy principles, is easy to access, understand, and use. Furthermore, our results reinforce the importance of diabetes nurses, as well as healthcare professionals in general, in encouraging patients to share their Internet findings, promote information from reliable sources, and deliver tailored information that suits individual needs. Because our results underline the importance of social support in eHealth literacy and the assessment of online health information, the inclusion of family and friends needs to be increasingly considered in diabetes care. Due to the small homogenous sample, the results of this study cannot be generalized. However, the reader can assess the transferability to other situations and settings based on our contextual descriptions.
