- To assess presence of virus DNA in skin lesions, swab samples from 82 squamous cell carcinomas of the skin (SCCs), 60 actinic keratoses (AKs), paraffin-embedded biopsies from 28 SCCs and 72 kerathoacanthomas (KAs) and fresh-frozen biopsies from 92 KAs, 85 SCCs and 92 AKs were analyzed by high throughput sequencing (HTS) using 454 or Ion Torrent technology. We found total of 4,284 viral reads, out of which 4,168 were Human Papillomavirus (HPV)-related, belonging to 15 known (HPV8, HPV12, HPV20, HPV36, HPV38, HPV45, HPV57, HPV59, HPV104, HPV105, HPV107, HPV109, HPV124, HPV138, HPV147), four previously described putative (HPV 915 F 06 007 FD1, FA73, FA101, SE42) and two putatively new HPV types (SE46, SE47). SE42 was cloned, sequenced, designated as HPV155 and found to have 76% similarity to the most closely related known HPV type. In conclusion, an unbiased approach for viral DNA detection in skin tumors has found that, although some new putative HPVs were found, known HPV types constituted most of the viral DNA.

- Cervical ripening is necessary for successful delivery. Since cytokines are believed to be involved in this process, the aim of this study was to investigate possible changes in the mRNA and protein expression of pro-inflammatory cytokines (interleukin (IL)-1 alpha, IL-1 beta, IL-12, IL-18) and anti-inflammatory cytokines (IL-4, IL-10, IL-13)in the human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 59 women: 21 at preterm labor, 24 at term labor, 10 at term not in labor and 4 from non-pregnant women. mRNA was analyzed with real-time RT-PCR and protein expression and/or secretion with immunohistochemistry and ELISA. There was an upregulation of mRNA for IL-10, IL-13, IL-1 alpha and IL-1 beta in the laboring groups, while mRNA for IL-12 and IL-18 was downregulated. IL-4 mRNA was detected more frequently, while IL-12 mRNA expression was lower, in the preterm labor group than in the term labor group. The protein levels of IL-4 and IL-12 were lower and IL-18 tended to be higher in the labor groups, while IL-10 protein levels were unaffected by labor. IL-4 protein levels were significantly higher in the preterm subgroup with bacterial infection than in the non-infected group. IL-10 had higher expression in squamous epithelium at preterm labor than at term. In conclusion, the major changes in pro-inflammatory and anti-inflammatory cytokine mRNA and protein expression in cervix occur during the labor process irrespective of the length of gestation. Our results indicate that dysregulation of anti-inflammatory cytokines in the human cervix could be involved in the pathogenesis of preterm labor.

- The limited understanding of the heterogeneity in the treatment response to antidiabetic drugs contributes to metabolic deterioration and cardiovascular complications 1,2, stressing the need for more personalized treatment 1. Although recent attempts have been made to classify diabetes into subgroups, the utility of such stratification in predicting treatment response is unknown 3. We enrolled participants with type 2 diabetes (n = 239, 74 women and 165 men) and features of severe insulin-deficient diabetes (SIDD) or severe insulin-resistant diabetes (SIRD). Participants were randomly assigned to treatment with the glucagon-like peptide 1 receptor agonist semaglutide or the sodium–glucose cotransporter 2 inhibitor dapagliflozin for 6 months (open label). The primary endpoint was the change in glycated haemoglobin (HbA1c). Semaglutide induced a larger reduction in HbA1c levels than dapagliflozin (mean difference, 8.2 mmol mol−1; 95% confidence interval, −10.0 to −6.3 mmol mol−1), with a pronounced effect in those with SIDD. No difference in adverse events was observed between participants with SIDD and those with SIRD. Analysis of secondary endpoints showed greater reductions in fasting and postprandial glucose concentrations in response to semaglutide in participants with SIDD than in those with SIRD and a more pronounced effect on postprandial glucose by dapagliflozin in participants with SIDD than in those with SIRD. However, no significant interaction was found between drug assignment and the SIDD or SIRD subgroup. In contrast, continuous measures of body mass index, blood pressure, insulin secretion and insulin resistance were useful in identifying those likely to have the largest improvements in glycaemic control and cardiovascular risk factors by adding semaglutide or dapagliflozin. Thus, systematic evaluation of continuous pathophysiological variables can guide the prediction of the treatment response to these drugs and provide more information than stratified subgroups (NCT04451837).

- This study was aimed at investigating the outcomes of an activity-based assessment (BIA) compared with standard assessment (SA) for evaluating clients undergoing psychiatric occupational therapy. Patients admitted to a psychiatric occupational therapy unit were randomized into the BIA or the SA assessment. The outcome indicators were (a) clients' satisfaction with the occupational therapy during the assessment period, (b) clients' awareness of capacities and occupational problems, (c) satisfaction with the assessment among the referring physicians, and (d) outcomes of the intervention following the assessment, in terms of changes in occupational performance and satisfaction. The groups did not differ in awareness of occupational problems, but the BIA group was more satisfied than the SA group with the support of their contact person and with the group leader during the period of assessment. Furthermore, physicians receiving feedback on patients in the BIA group were more satisfied than those receiving feedback on patients in the SA group. However, the groups did not differ concerning change during the treatment period in occupational performance or satisfaction. Thus, there was no difference between the assessment methods regarding the outcomes of the treatment following assessment. Minor advantages from the patients' perspective were found, in terms of better satisfaction in the BIA group, and from the referring physicians' perspective the BIA clearly seemed more satisfying than the SA. Thus, the findings showed that the BIA possessed better qualities than the SA regarding the indicators pertaining to satisfaction, but not concerning awareness of capacities and problems or the outcome of the subsequent treatment.

- Purpose: To describe the clinical expressions, with emphasis on electrophysiological examinations, in two Swedish families with Stargardt's macular dystrophy (STGD1). Methods. Two pairs of siblings with STGD1, for whom diagnosis had been confirmed by genetic linkage to the ABCA4 gene region, were examined regarding visual acuity, kinetic perimetry, fundus photography, full-field ERG and multifocal ERG (MERG). Possible disease-causing mutations were screened for by DNA sequencing of selected regions of the ABCA4 gene. Results. All STGD1 patients, had visual acuity 0.07-0.1. The two families presented different fundus appearances, MERGs and implicit times on. 30 Hz flicker white light full-field ERGs. Genetic analysis revealed one unique sequence variation in exon 19 of the ABCA4 gene, in one allele from the patients of one of the families. This point mutation causes the amino acid substitution T972N in the ABCR protein. Conclusion. Two pairs of siblings with STGD1 presented two different expressions of the disease regarding the distribution of the retinal dysfunction. One possible molecular explanation to the different clinical expressions may be the T972N substitution present in the ABCR protein in one of the STGD1 families investigated.

- BackgroundThe risks of developmental language disorder (DLD) for both educational progress and socio-emotional development are well documented, but little is known about how children and young people with DLD experience and describe their language and communication. The need to complement experimental and quantitative studies with qualitative perspectives of the lived experience of individuals with DLD for speech and language therapists (SLT) practice has recently been foregrounded. AimsTo understand further the experiences of young people with DLD focusing on language and communication in a school context, and thereby contribute to the improvement of the communicative situation in school for this group. The study is guided by the following research question: How do young people diagnosed with DLD describe their experiences of language and communication in school? Methods & ProceduresThe study is based on data generated from qualitative semi-structured interviews with 23 participants diagnosed with DLD (age 13-19 years old) living in Sweden. All participants attended mainstream schools. To enable data to be collected during COVID-19 restrictions, all interviews were conducted using Zoom. Reflexive thematic analysis was used to analyse the data. Outcomes & ResultsFour main themes related to experiences of language and communication in school were constructed from the interviews: (1) feelings of inadequacy and comparisons with others; (2) feelings of being misjudged and misunderstood; (3) the importance of feeling safe and comfortable; and (4) the significance of the social and communicative context. The results bear witness of difficult and challenging aspects related to language and communication in school, including educational, social and emotional dimensions. An important outcome of this study is how young people diagnosed with DLD describe their language and communication functioning to be dependent on both individual characteristics and abilities, as well as situational, contextual and social factors. Conclusions & ImplicationsThe results from this study show that young people with DLD can have persisting problems related to language and communication in school, including educational, social and emotional dimensions. SLT services may therefore be needed throughout the school years to ensure that students with DLD receive adequate support. In addition, support that goes beyond language abilities and targets social, contextual and emotional aspects should be considered. WHAT THIS PAPER ADDSWhat is already known on this subjectChildren and young people have unique knowledge about their language and communication which is instrumental for designing interventions and support strategies. Qualitative analyses of interview data have been able to identify both risk factors and protective strategies in relation to the well-being of individuals with DLD. Despite this, children and young people with DLD are rarely heard in research or clinical discussions. What this paper adds to existing knowledgeIn this study we listen to the voices of young people with DLD as they describe their experiences of language and communication in school. The participants describe a condition that makes them struggle to keep up with peers and puts them at risk of being misjudged by teachers, but also give examples of situations where negative consequences are hardly felt. What are the potential or actual clinical implications of this work?DLD is a complex and dynamic disorder where contextual and social factors interact with individual abilities in creating the end result. The results of the study indicate that DLD can cause persisting problems related to language and communication in school, with impact on educational, social and emotional dimensions. To counteract these effects, SLT services may be needed throughout the school years, and support that goes beyond language abilities must be considered.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Språkstörning är en funktionsnedsättning som förekommer hos cirka sju procent av alla barn. Eftersom skolans undervisning förutsätter en god språklig förmåga, är risken stor att dessa elever inte når skolans mål. I detta pågående projekt undersöks situationen för elever med språkstörning i den svenska skolan med både kvantitativa och kvalitativa undersökningar.
