- Occupational therapists need an instrument to assess executive dysfunctions before patients are discharged from acute wards. The Executive Function Performance Test (EFPT) appears to be suitable, since it evaluates dysfunctions in complex activities. The aim of this study was to translate the EFPT from English into Swedish and to evaluate its properties when used with older persons with mild stroke in an acute setting. Method The study consisted of three parts: (1) a translation procedure using a forward and backward method; (2) evaluation of face validity; (3) inter-rater reliability by four raters (two pairs) who made 34 assessments in 17 older patients with mild stroke in an acute ward. Results The inter-rater reliability for the EFPT was good. The median was 88% of the percentage agreement. No occasional disagreement was found between the raters, but there was a systematic disagreement in one out of 20 items. The translation and face validity process resulted in further clarification of the semantic and cultural equivalence of the EFPT, and the manual was changed accordingly. Conclusion This study showed that inter-rater reliability was good and that the EFPT was found to be an interesting assessment, although further research is needed.

- Background: Studies have shown that patients with hip fracture treated in a Comprehensive Geriatric Care (CGC) unit report better results in comparison to orthopaedic care. Furthermore, involving patients in their healthcare by encouraging patient participation can result in better quality of care and improved outcomes. To our knowledge no study has been performed comparing rehabilitation programmes within a CGC unit during the acute phase after hip fracture with focus on improving patients' perceived participation and subsequent effect on patients' function. Methods: A prospective, controlled, intervention performed in a CGC unit and compared with standard care. A total of 126 patients with hip fracture were recruited who were prior to fracture; community dwelling, mobile indoors and independent in personal care. Intervention Group (IG): 63 patients, mean age 82.0 years and Control Group (CG): 63 patients mean age 80.5 years. Intervention: coordinated rehabilitation programme with early onset of patient participation and intensified occupational therapy and physiotherapy after hip fracture surgery. The primary outcome measure was self-reported patient participation at discharge. Secondary outcome measures were: TLS-BasicADL; Bergs Balance Scale (BBS); Falls Efficacy Scale FES(S); Short Physical Performance Battery (SPPB) and Timed Up and Go (TUG) at discharge and 1 month and ADL staircase for instrumental ADL at 1 month. Results: At discharge a statistically significant greater number of patients in the IG reported higher levels of participation (p < 0.05) and independence in lower body hygiene (p < 0.05) and dressing (p < 0.001). There were however no statistically significant differences at discharge and 1 month between groups in functional balance and confidence, performance measures or risk for falls. Conclusion: This model of OT and PT coordinated inpatient rehabilitation had a positive effect on patients' perceived participation in their rehabilitation and ADL at discharge but did not appear to affect level of recovery or risk for future falls at 1 month. A large proportion of patients remained at risk for future falls at 1 month in both groups highlighting the need for continued rehabilitation after discharge.

- Genome-wide association studies have identified risk loci for SLE, but a large proportion of the genetic contribution to SLE still remains unexplained. To detect novel risk genes, and to predict an individual's SLE risk we designed a random forest classifier using SNP genotype data generated on the "Immunochip" from 1,160 patients with SLE and 2,711 controls. Using gene importance scores defined by the random forest classifier, we identified 15 potential novel risk genes for SLE. Of them 12 are associated with other autoimmune diseases than SLE, whereas three genes (ZNF804A, CDK1, and MANF) have not previously been associated with autoimmunity. Random forest classification also allowed prediction of patients at risk for lupus nephritis with an area under the curve of 0.94. By allele-specific gene expression analysis we detected cis-regulatory SNPs that affect the expression levels of six of the top 40 genes designed by the random forest analysis, indicating a regulatory role for the identified risk variants. The 40 top genes from the prediction were overrepresented for differential expression in B and T cells according to RNA-sequencing of samples from five healthy donors, with more frequent over-expression in B cells compared to T cells.

- Objectives: Systemic lupus erythematosus (SLE) is a chronic autoimmune condition with heterogeneous presentation and complex aetiology where DNA methylation changes are emerging as a contributing factor. In order to discover novel epigenetic associations and investigate their relationship to genetic risk for SLE, we analysed DNA methylation profiles in a large collection of patients with SLE and healthy individuals.Methods: DNA extracted from blood from 548 patients with SLE and 587 healthy controls were analysed on the Illumina HumanMethylation 450 k BeadChip, which targets 485 000 CpG sites across the genome. Single nucleotide polymorphism (SNP) genotype data for 196 524 SNPs on the Illumina ImmunoChip from the same individuals were utilised for methylation quantitative trait loci (cis-meQTLs) analyses.Results: We identified and replicated differentially methylated CpGs (DMCs) in SLE at 7245 CpG sites in the genome. The largest methylation differences were observed at type I interferon-regulated genes which exhibited decreased methylation in SLE. We mapped cis-meQTLs and identified genetic regulation of methylation levels at 466 of the DMCs in SLE. The meQTLs for DMCs in SLE were enriched for genetic association to SLE, and included seven SLE genome-wide association study (GWAS) loci: PTPRC (CD45), MHC-class III, UHRF1BP1, IRF5, IRF7, IKZF3 and UBE2L3. In addition, we observed association between genotype and variance of methylation at 20 DMCs in SLE, including at the HLA-DQB2 locus.Conclusions: Our results suggest that several of the genetic risk variants for SLE may exert their influence on the phenotype through alteration of DNA methylation levels at regulatory regions of target genes.

- Objectives: To performa cross-comparative analysis of DNA methylation in patients with systemic lupus erythematosus (SLE), patients with primary Sjogren's syndrome (pSS), and healthy controls addressing the question of epigenetic sharing and aiming to detect disease-specific alterations. Methods: DNA extracted from peripheral blood from 347 cases with SLE, 100 cases with pSS, and 400 healthy controls were analyzed on the Human Methylation 450k array, targeting 485,000 CpG sites across the genome. A linear regression model including age, sex, and blood cell type distribution as covariates was fitted, and association p-values were Bonferroni corrected. A random forest machine learning classifier was designed for prediction of disease status based on DNA methylation data. Results: We established a combined set of 4,945 shared differentially methylated CpG sites (DMCs) in SLE and pSS compared to controls. In pSS, hypomethylation at type I interferon induced genes was mainly driven by patients who were positive for Ro/SSA and/or La/SSB autoantibodies. Analysis of differential methylation between SLE and pSS identified 2,244 DMCs with a majority of sites showing decreased methylation in SLE compared to pSS. The random forest classifier demonstrated good performance in discerning between disease status with an area under the curve (AUC) between 0.83 and 0.96. Conclusions: The majority of differential DNA methylation is shared between SLE and pSS, however, important quantitative differences exist. Our data highlight neutrophil dysregulation as a shared mechanism, emphasizing the role of neutrophils in the pathogenesis of systemic autoimmune diseases. The current study provides evidence for genes and molecular pathways driving common and disease-specific pathogenic mechanisms.

- Objectives - Studies suggest that fatigue and cognitive impairment may be present after transient ischemic attack (TIA), but little is known about consequences in daily life. The main aim was to longitudinally explore the presence of fatigue, cognitive impairment, and consequences in daily life including communication after clinically diagnosed TIA at 1 and 9 months after the event. Material and methods - A consecutive sample of 46 patients (23 women, 69 +/- 12.3 years) was assessed at discharge from hospital and at 1 and 9 months after TIA regarding cognition, mental fatigue, tiredness, and activities of daily life. This served as basis for an interview concerning experienced changes related to the TIA. Results - Problems in daily life with probable association with the TIA were experienced by 37% (n = 45) of participants 9 months after the TIA event. Cognitive impairment was present in 40% (n = 44) after 1 month and 30% (n = 23) after 9 months. Mental fatigue was experienced by 26% (n = 42) after 1 month and 17% (n = 39) after 9 months. Communication problems were reported and increased from 7 to 14 participants between the two time points. Conclusions - A third of the TIA patients experienced problems in performance of complex activities in daily life and often communication problems within the first 9 months. Cognitive impairment and mental fatigue could be factors influencing performance in daily life and at work, but this needs to be verified in a larger sample. The risk of activity limitations indicates need for multiprofessional support and systematic routines for TIA follow-up.

- The aim of this study was to explore the experiences, needs, and preferences regarding follow-up perceived by people with stroke and healthcare professionals.This is a qualitative exploratory study using focus groups. Patients and healthcare professionals, participating in a clinical visit in primary care or specialised care, were purposively sampled. Data were analysed using a framework of analysis developed by Krueger.Focus groups were conducted with two patient groups (n = 10, range 45-78 years) and two multidisciplinary healthcare professional groups (n = 8, range 35-55 years). The overarching theme elucidates stroke as a long-term condition requiring complex follow-up. Three organisational themes and six subthemes were identified. People with stroke discovered feelings and changes after returning home. In daily life, problems and feelings of abandonment became evident. Participants expressed experiences of unequal access to health care services. Barriers for accessing appropriate treatment and support included difficulties in communicating one's needs and lack of coherent follow-up. Follow-up activities were well functioning in certain clinics but did not provide continuity over the long term. Participants made suggestions for a comprehensive, planned, and tailored follow-up to meet patient needs.Comprehensive long-term follow-up that is accessible to all patients is essential for equal support. Our findings raised awareness about problems discovered after returning home and the obstacles individuals face in communicating their needs. Structured follow-up, which is individually tailored, can empower patients.

- The wide range of outcomes after stroke emphasises the need for comprehensive long-term follow-up. The aim was to evaluate how people with stroke and health professionals (HPs) perceive the use of the poststroke checklist (PSC), with a focus on feasibility and relevance.An exploratory design with a mix of qualitative and quantitative methods.Outpatient care at a university hospital and primary care centres in western Sweden.Forty-six consecutive patients (median age, 70; range, 41-85; 13 women) and 10 health professionals (median age 46; range, 35-63; 7 women).Most patients (87%) had one or more problems identified by the PSC. The most common problem areas were life after stroke (61%), cognition (56%), mood (41%) and activities of daily living (39%). Three organisational themes emerged from the focus group discussions. The perception of the content and relevance of the PSC was that common poststroke problems were covered but that unmet needs still could be missed. Identifying needs was facilitated when using the PSC as a tool for dialogue. The dialogue between the patient and HP as well as HPs stroke expertise was perceived as important. The PSC was seen as a systematic routine and a base for egalitarian follow-up, but participants stressed consideration given to each individual. Addressing identified needs and meeting patient expectations were described as challenging given available healthcare services.The PSC is a feasible and relevant tool to support egalitarian follow-up and identify patients who could benefit from targeted poststroke interventions. Stroke expertise, room for dialogue and caring for identified needs emerged as important issues to consider when using the PSC. Nutrition, sexuality and fatigue were areas mentioned that might need to be addressed within the discussions. The PSC can facilitate patients in expressing their needs, enhancing their ability to participate in decision-making.
