Cerebrospinal fluid levels of neuroinflammatory biomarkers are increased in athletes with persistent post-concussive symptoms following sports-related concussion.

A sports-related concussion (SRC) is often caused by rapid head rotation at impact, leading to shearing and stretching of axons in the white matter and initiation of secondary inflammatory processes that may exacerbate the initial injury. We hypothesized that athletes with persistent post-concussive symptoms (PPCS) display signs of ongoing neuroinflammation, as reflected by altered profiles of cerebrospinal fluid (CSF) biomarkers, in turn relating to symptom severity. We recruited athletes with PPCS preventing sports participation as well as limiting work, school and/or social activities for ≥ 6 months for symptom rating using the Sport Concussion Assessment Tool, version 5 (SCAT-5) and for cognitive assessment using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Following a spinal tap, we analysed 27 CSF inflammatory biomarkers (pro-inflammatory chemokines and cytokine panels) by a multiplex immunoassay using antibodies as electrochemiluminescent labels to quantify concentrations in PPCS athletes, and in healthy age- and sex-matched controls exercising ≤ 2 times/week at low-to-moderate intensity. Thirty-six subjects were included, 24 athletes with PPCS and 12 controls. The SRC athletes had sustained a median of five concussions, the most recent at a median of 17 months prior to the investigation. CSF cytokines and chemokines levels were significantly increased in eight (IL-2, TNF-α, IL-15, TNF-ß, VEGF, Eotaxin, IP-10, and TARC), significantly decreased in one (Eotaxin-3), and unaltered in 16 in SRC athletes when compared to controls, and two were un-detectable. The SRC athletes reported many and severe post-concussive symptoms on SCAT5, and 10 out of 24 athletes performed in the impaired range (Z < - 1.5) on cognitive testing. Individual biomarker concentrations did not strongly correlate with symptom rating or cognitive function. Limitations include evaluation at a single post-injury time point in relatively small cohorts, and no control group of concussed athletes without persisting symptoms was included. Based on CSF inflammatory marker profiling we find signs of ongoing neuroinflammation persisting months to years after the last SRC in athletes with persistent post-concussive symptoms. Since an ongoing inflammatory response may exacerbate the brain injury these results encourage studies of treatments targeting the post-injury inflammatory response in sports-related concussion.

Comprehensive and Structured 3-month Stroke Follow-up Using the Post-stroke Checklist (The Struct-FU study): A Feasibility and Explorative Study.

BACKGROUND: There is recent evidence supporting that a comprehensive post-stroke treatment program improves outcome. However, the prevalence of stroke-related health problems and the extent of needed interventions have not been well-delineated. The Struct-FU study aims to assess the feasibility of a comprehensive stroke follow-up model and to map stroke-related problems and subsequent multidisciplinary interventions using a modified Post-stroke Checklist (PSC). METHODS: We consecutively screened all acute stroke patients at Skåne University Hospital, Sweden during an eight-month period in 2018-2019. Patients discharged to own home were eligible for inclusion. We defined a stroke-related health problem as a health- or social issue corresponding to one of the 14 items in the modified PSC, and with onset after the stroke event. Three-months post-stroke, a semi-structured interview using a 14-item modified PSC was completed to map the prevalence of stroke-related health problems, as well as any subsequent multidisciplinary stroke team interventions prompted by the visit. RESULTS: The number of included patients was 200. Of these, 165 (82.9%) completed three-month follow-up, one died, and 34 were lost to follow-up. All patients completed the full PSC, and the majority (92.7%) reported stroke-related problems identified using the PSC, with the median number being three per patient, and half having four or more problems. Patients <=65 years (n=44) presented with more stroke-related problems than patients >65 years (n=121) (5 vs. 3, p=0.003). The median number of interventions was two per patient. Doctor's interventions (changes in medication, referrals or further work-up) were done in 53% of patients, 77% needed a nurse's or other stroke team professional's intervention (tailored advice, information, audits, rehabilitation assessments) and 15% needed no intervention. Only 3.6% of patients reported other stroke-related challenges (PSC item 14) than those specified in item 1-13. CONCLUSION: We report a high burden of stroke-related health problems in community dwelling stroke patients with mild to moderate stroke. Multidisciplinary interventions were prompted in the vast majority (85%). Only 3.6% of patients reported challenges not captured with the Post-stroke Checklist, reflecting that the comprehensive approach captures the majority of stroke-related health problems, and gives a good estimate of the total stroke-related health burden for each individual.

Physical activity and risk of Amyotrophic Lateral Sclerosis in a prospective cohort study.

Previous case-control studies have suggested a possible increased risk of Amyotrophic Lateral Sclerosis (ALS) with physical activity (PA), but this association has never been studied in prospective cohort studies. We therefore assessed the association between PA and risk of death from ALS in the European Prospective Investigation into Cancer and Nutrition. A total of 472,100 individuals were included in the analysis, yielding 219 ALS deaths. At recruitment, information on PA was collected thorough standardised questionnaires. Total PA was expressed by the Cambridge Physical Activity Index (CPAI) and analysed in relation to ALS mortality, using Cox hazard models. Interactions with age, sex, and anthropometric measures were assessed. Total PA was weakly inversely associated with ALS mortality with a borderline statistically significant trend across categories (p = 0.042), with those physically active being 33% less likely to die from ALS compared to those inactive: HR = 0.67 (95% CI 0.42-1.06). Anthropometric measures, sex, and age did not modify the association with CPAI. The present study shows a slightly decreased-not increased like in case-control studies-risk of dying from ALS in those with high levels of total PA at enrolment. This association does not appear confounded by age, gender, anthropometry, smoking, and education. Ours was the first prospective cohort study on ALS and physical activity.

Secondary prevention and health promotion after stroke: can it be enhanced?

The aim was to study if health outcome and secondary prevention were satisfactory 1 year after stroke and if nurse-led interventions 3 months after stroke could have impact. Design was a randomized controlled open trial in a 1-year population. Primary outcome was health status 1 year after stroke. One month after stroke, survivors were randomized into intervention group (IG) with follow-up by a specialist nurse (SN) after 3 months (n = 232), and control group (CG) with standard care (n = 227), all to be followed up 1 year after stroke. At the first follow-up, patients graded their health, replied to the EuroQol-5 Dimensions (EQ-5D) health outcome questions, health problems were assessed, and supportive counseling was provided in the IG. Health problems requiring medical interventions were primarily referred to a general practitioner (GP). One year after stroke, 391 survivors were followed up. Systolic blood pressure (BP) had decreased in IG (n = 194) from median 140 to 135 (P = .05), but about half were above the limit 139 in both groups. A larger proportion (22%) had systolic BP >155 in the CG (n = 197) than in the IG (14%; P = .05). In the IG, 62% needed referrals compared with the 75% in the CG (P = .009). Forty percent in the IG and 52.5% in the CG (P = .04) reported anxiety/depression. In the IG, 75% and 67% in the CG rated their general health as fairly good or very good (P = .05). Although nurse-led interventions could have some effect, the results were not optimal. A more powerful strategy could be closer collaboration between the SN and a stroke clinician, before referring to primary care.

Experiences of chain of care and rehabilitation after stroke: a qualitative study of persons discharged to skilled nursing facilities before returning home.

OBJECTIVE: To explore how people with stroke, discharged to skilled nursing facilities before returning home, experience the chain of care and rehabilitation. DESIGN: Qualitative, semi-structured interview design. METHODS: Thirteen stroke survivors discharged from a stroke unit to a skilled nursing facility before returning to independent living participated. Semi-structured telephone interviews were conducted 2-5 months after stroke and analysed with content analysis. RESULTS: The analysis resulted in three categories, Organizational processes, critical and complex, Rehabilitation, the right support at the right time and Adaptation to the changed situation, with a total of 9 subcategories. The informants perceived low participation in planning and goalsetting and limited information. Support from the healthcare services was important to proceed with improvements although the amount of supported training varied. Factors hindering and facilitating managing everyday life were described, as well as lingering uncertainty of what the future would be like. CONCLUSION: Support and rehabilitation as well as individuals' needs varied, throughout the chain of care. To enable participation in the rehabilitation, assistance in setting goals and repeated information is warranted. Tailored care and rehabilitation throughout the chain of care should be provided, followed up at home, and coordinated for smooth transitions between organizations.

Prevalence and disease disability in immigrants with multiple sclerosis in Malmö, southern Sweden.

BACKGROUND: Multiple sclerosis (MS) is the most common chronic demyelinating disease of the central nervous system and the major non-traumatic cause of permanent disability in young adults. Several migration studies have been performed over the years suggesting a pattern of higher disease disability in certain ethnic groups. To our knowledge, differences in disease progression in immigrants have not been studied in Sweden before. Thus, the aims of our study were to estimate the prevalence of multiple sclerosis among first-generation immigrants in the City of Malmö and to compare differences in disease severity with the native population. METHODS: All persons with multiple sclerosis living in Malmö on prevalence day 31 Dec 2010 were included. Cases were classified according to the country of birth into Scandinavians, Western and non-Western. RESULTS: The crude prevalence was 100/100,000 (95% CI, 80-124) among first-generation immigrants, 154/100,000 (95% CI, 137-173) among individuals with Scandinavian background, 123/100,000 (95% CI, 94-162) in the Western group and 76/100,000 (95% CI, 53-108) in the non-Western group. The mean Multiple Sclerosis Severity Score (MSSS) value among Scandinavians was 4.2 (SD 3.5), whereas the figures in the immigrant group were 4.6 (SD 3.3) and 5.2 (SD 3.7) among Westerns respectively non-Westerns, which differences were not statistically significant. When adjusting for gender, age at onset and initial disease course, the mean MSSS difference between the non-Western and the Scandinavian individuals was 1.7 (95% CI 0.18-3.3, p = 0.030). There were no differences on time to diagnosis or the time from diagnosis to treatment initiation between the three groups. CONCLUSIONS: We found a lower prevalence among Western and non-Western first-generation immigrants compared to the Scandinavian population and a more severe disease in non-Western immigrants than in Scandinavians.

Rehabilitation at Home With the Development of a Sustainable Model Placing the Person's Needs and Environment at Heart: Protocol for a Multimethod Project.

BACKGROUND: Each year, more than 1.5 million people in Europe have a stroke, and many experience disabilities leading to activity and participation restrictions. Home-based rehabilitation is the recommended approach for stroke rehabilitation, in line with the international shift to integrated care. Despite this, rehabilitation often focuses on the person's physical functions, not the whole life situation and opportunities to live an active life. Given that rehabilitation today is often provided in the person's home, there is a need to develop new models that consider the rehabilitation process as situated in the everyday living environment of persons with stroke. This project is grounded in experiences from our ongoing research, where we study the importance of the home environment for health and participation among persons with stroke, rehabilitated at home. This research has shown unmet needs, which lead to suboptimal rehabilitation outcomes. There is a need for studies on how to use environmental resources to optimize stroke rehabilitation in the home setting. OBJECTIVE: The overarching objective of the project is to develop a new practice model for rehabilitation where the needs of the person are the starting point and where the environment is considered. METHODS: The project will be conducted in partnership with persons with stroke, significant others, health care professionals, and care managers. Results from a literature review will form the base for interviews with the stakeholders, followed by co-designing workshops aiming to create a new practice model. Focus groups will be held to refine the outcome of the workshops to a practice model. RESULTS: This 4-year project commenced in January 2023 and will continue until December 2026. The results of the literature review are, as of April 2024, currently being analyzed. The ethics application for the interviews and co-design phase was approved in October 2023 and data collection is ongoing during spring 2024. We aim to develop a practice model with stakeholders and refine it together with care managers and decision makers. The outcome is a new practice model and implementation plan, which will be achieved in autumn 2026. CONCLUSIONS: The project contributes with a prominent missing puzzle to optimize the rehabilitation process by adding a strong focus on user engagement combined with integrating different aspects of the environment. The goal is to improve quality of life and increase reintegration in society for the large group of people living with the aftermath of a stroke. By co-designing with multiple stakeholders, we expect the model to be feasible and sustainable. The knowledge from the project will also contribute to an increased awareness of the importance of the physical environment for sustainable health care. The findings will lay the foundation for future upscaling initiatives. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/56996.

Widespread White Matter Abnormalities in Concussed Athletes Detected by 7T Diffusion Magnetic Resonance Imaging.

Sports-related concussions may cause white matter injuries and persistent post-concussive symptoms (PPCS). We hypothesized that athletes with PPCS would have neurocognitive impairments and white matter abnormalities that could be revealed by advanced neuroimaging using ultra-high field strength diffusion tensor (DTI) and diffusion kurtosis (DKI) imaging metrics and cerebrospinal fluid (CSF) biomarkers. A cohort of athletes with PPCS severity limiting the ability to work/study and participate in sport school and/or social activities for ≥6 months completed 7T magnetic resonance imaging (MRI) (morphological T1-weighed volumetry, DTI and DKI), extensive neuropsychological testing, symptom rating, and CSF biomarker sampling. Twenty-two athletes with PPCS and 22 controls were included. Concussed athletes performed below norms and significantly lower than controls on all but one of the psychometric neuropsychology tests. Supratentorial white and gray matter, as well as hippocampal volumes did not differ between concussed athletes and controls. However, of the 72 examined white matter tracts, 16% of DTI and 35% of DKI metrics (in total 28%) were significantly different between concussed athletes and controls. DKI fractional anisotropy and axial kurtosis were increased, and DKI radial diffusivity and radial kurtosis decreased in concussed athletes when compared with controls. CSF neurofilament light (NfL; an axonal injury marker), although not glial fibrillary acidic protein, correlated with several diffusion metrics. In this first 7T DTI and DKI study investigating PPCS, widespread microstructural alterations were observed in the white matter, correlating with CSF markers of axonal injury. More white matter changes were observed using DKI than using DTI. These white matter alterations may indicate persistent pathophysiological processes following concussion in sport.

[Rehabilitation of stroke in a ¼chain of care« perspective]. / Strokerehabilitering ur ett vårdkedjeperspektiv.

Rehabilitation is a key aspect of the treatment of stroke patients, both acute and in later phases. The patients' needs varies between individuals and over time. Several skills and methods and different professionals working together in teams, as well as coordination along the entire chain of care, are required in order to meet those different needs. Early supported discharge, ESD, is recommended for patients with mild to moderate stroke. Stroke is a chronic disease requiring lifelong structured follow-up focusing not only on medical treatment but also on lifestyle, mental and physical well-being and activity and participation.

Built Environments to Support Rehabilitation for People With Stroke From the Hospital to the Home (B-Sure): Protocol for a Mixed Method Participatory Co-Design Study.

BACKGROUND: A global trend is to move rehabilitation closer to people's neighborhoods and homes. Still, little attention has been given to how the built environment outside the hospital setting might impact rehabilitation and recovery for stroke survivors. OBJECTIVE: The overarching objective of this project is to develop conceptual models of built environments that support stroke rehabilitation and recovery outside the hospital setting. Specifically, the project will explore factors and characteristics of the built environment that support people with stroke and their families and identify innovative built environments that can be designed for local health care. The project will examine facilitators and obstacles for implementing built environmental solutions and evaluate the potential benefits, feasibility, and acceptability. METHODS: The project uses a mixed methods design approach with 3 phases. In phase 1, factors and characteristics of the built environment for rehabilitation will be identified. Based on the results from phase 1, phase 2 will involve co-designing prototypes of environments to support the rehabilitation process for people with stroke. Finally, the prototypes will be evaluated in phase 3. Qualitative and quantitative methods will include a literature review, a concept mapping (CM) study, stakeholder interviews, prototype development, and testing. The project will use multidimensional scaling, hierarchical cluster analysis, descriptive statistics for quantitative data, and content analysis for qualitative data. Location analysis will rely on the location-allocation model for network problems, and the rule-based analysis will be based on geographic information systems data. RESULTS: As of the submission of this protocol, ethical approval for the CM study and the interview study has been obtained. Data collection is planned to start in September 2023 and the workshops later in the same year. The scoping review is ongoing from January 2023. The CM study is ongoing and will be finalized in the spring of 2024. We expect to finish the data analysis in the second half of 2024. The project is a 3-year project and will continue until December 2025. CONCLUSIONS: We aim to determine how new environments could better support a person's control over their day, environment, goals, and ultimately control over their recovery and rehabilitation activities. This "taking charge" approach would have the greatest chance of transferring the care closer to the patient's home. By co-designing with multiple stakeholders, we aim to create solutions with the potential for rapid implementation. The project's outcomes may target other people with frail health after a hospital stay or older persons in Sweden and anywhere else. The impact and social benefits include collaboration between important stakeholders to explore how new environments can support the transition to local health care, co-design, and test of new conceptual models of environments that can promote health and well-being for people post stroke.

Perceived work situation and work ability among persons who are working one year after stroke.

OBJECTIVE: To explore how persons who have returned to work perceive their work situation and work ability one year after stroke. DESIGN: Cross-sectional design. SUBJECTS: A total of 88 persons of working age (mean age 52 (standard deviation; SD 8) years, 36% women), with mild to moderate disabilities following stroke, who had returned to work within one year after stroke participated in the study. METHODS: A survey including a questionnaire regarding psychological and social factors at work (QPS Nordic) and 4 questions from the Work Ability Index (WAI) was posted to the participants. RESULTS: According to the QPS Nordic survey, 69-94% of respondents perceived their work duties as well defined, and were content with their work performance. Most participants had good social support at work and at home. Between 51% and 64% of respondents reported that they seldom felt stressed at work, seldom had to work overtime, or that work demands seldom interfered with family life. According to the WAI ≥75% of respondents perceived their work ability as sufficient, and they were rather sure that they would still be working 2 years ahead. CONCLUSION: Persons who have returned to work within one year after stroke appear to be content with their work situation and work ability. Appreciation at work, well-defined and meaningful work duties and support seem to be important for a sustainable work situation.

Efficacy and feasibility of SENSory relearning of the UPPer limb (SENSUPP) in people with chronic stroke: A pilot randomized controlled trial.

BACKGROUND: Sensorimotor impairments of the upper limb (UL) are common after stroke, but there is a lack of evidence-based interventions to improve functioning of UL. OBJECTIVE: To evaluate (1) the efficacy of sensory relearning and task-specific training compared to task-specific training only, and (2) the feasibility of the training in chronic stroke. DESIGN: A pilot randomized controlled trial. SETTING: University hospital outpatient clinic. PARTICIPANTS: Twenty-seven participants (median age; 62 years, 20 men) were randomized to an intervention group (IG; n = 15) or to a control group (CG; n = 12). INTERVENTION: Both groups received training twice weekly in 2.5-hour sessions for 5 weeks. The training in the IG consisted of sensory relearning, task-specific training, and home training. The training in the CG consisted of task-specific training. MAIN OUTCOME MEASURES: Primary outcome was sensory function (touch thresholds, touch discrimination, light touch, and proprioception). Secondary outcomes were dexterity, ability to use the hand in daily activities, and perceived participation. A blinded assessor conducted the assessments at baseline (T1), post intervention (T2), and at 3-month follow-up (T3). Nonparametric analyses and effect-size calculations (r) were performed. Feasibility was evaluated by a questionnaire. RESULTS: After the training, only touch thresholds improved significantly from T1 to T2 (p = .007, r = 0.61) in the IG compared to the CG. Within the IG, significant improvements were found from T1 to T2 regarding use of the hand in daily activities (p = .001, r = 0.96) and movement quality (p = .004, r = 0.85) and from T1 to T3 regarding satisfaction with performance in meaningful activities (p = .004, r = 0.94). The CG significantly improved the performance of using the hand in meaningful activities from T1 to T2 (p = .017, r = 0.86). The training was well tolerated by the participants and performed without any adverse events. CONCLUSIONS: Combined sensory relearning and task-specific training may be a promising and feasible intervention to improve UL sensorimotor function after stroke.

Patient Participation and the Environment: A Scoping Review of Instruments.

Patient participation and the environment are critical factors in achieving qualitative healthcare. We conducted a systematic scoping review using Arksey and O'Malley's framework to identify instruments intended to measure patient participation. We assessed those instruments' characteristics, which areas of the healthcare continuum they target, and whether environmental factors are considered. Instruments were considered eligible if they represented the patient perspective and measured patient participation in healthcare. The search was limited to articles written in English and published in the last 10 years. We extracted concepts (i.e., patient empowerment, patient participation, and patient-centeredness) based on the framework developed by Castro et al. and outcomes of significance regarding the review questions and specific objectives. The search was conducted in PsycINFO, CINHAL/EBSCO, and PubMed in September 2019 and July 2020. Of 4802 potential titles, 67 studies reported on a total of 45 instruments that met the inclusion criteria for this review. The concept of patient participation was represented most often in these studies. Although some considered the social environment, no instrument was found to incorporate and address the physical environment. Thirteen instruments were generic and the remaining instruments were intended for specific diagnoses or healthcare contexts. Our work is the first to study instruments from this perspective, and we conclude that there is a lack of instruments that measure aspects of the social and physical environment coherently as part of patient participation.

Experiences of SENSory Relearning of the UPPer Limb (SENSUPP) after Stroke and Perceived Effects: A Qualitative Study.

Recently, it was shown that sensory relearning of the upper limb (SENSUPP) is a promising intervention to improve sensorimotor function after stroke. There is limited knowledge, however, of how participants perceive the training. Here, we explored how persons with sensory impairments in the upper limb experienced the SENSUPP protocol (combined sensory- and motor training and home exercises for 5 weeks) and its effect. Fifteen persons (mean age 59 years; 10 men; >6 months post-stroke) were individually interviewed, and data were analyzed with qualitative content analysis. An overall theme 'Sensory relearning was meaningful and led to improved ability to perform daily hand activities' and two categories with six subcategories emerged. The outpatient training was perceived as meaningful, although the exercises were demanding and required concentration. Support from the therapist was helpful and training in small groups appreciated. The home training was challenging due to lack of support, time, and motivation. Small improvements in sensory function were perceived, whereas increased movement control and ability in performing daily hand activities were reported. In conclusion, the SENSUPP protocol is meaningful and beneficial in improving the functioning of the UL in chronic stroke. Improving compliance to the home training, regular follow-ups, and an exercise diary are recommended.

Incidence and Prevalence of Multiple Sclerosis in Malmö, Southern Sweden.

Objectives: To estimate the incidence and prevalence of multiple sclerosis (MS) in Malmö municipality in southwestern Sweden. Materials and Methods: Multiple sources were used in the case identification process. Case ascertainment was assessed by medical chart review including examinations such as magnetic resonance imaging, cerebrospinal fluid analyses, and relevant laboratory tests. Cases were classified according to the 2010 McDonald's diagnostic criteria. Onset-adjusted prevalence and a definition of onset symptoms were applied. Results: The crude incidence of MS in 2001-2010 in Malmö municipality was 5.3/100,000 (95% confidence interval (CI): 4.5 to 6.2). There was a relapsing onset in 90.5% of cases. The female to male ratio was 1.8. The onset-adjusted prevalence for Dec 2010 was 133/100,000 (95% CI, 120 to 146) with a female to male ratio of 2.1. Conclusions: This is the first population-based epidemiological study in Skåne, the most southwestern part of Sweden showing a high incidence and prevalence. We found a lower incidence than expected according to previous nationwide figures, probably due to methodological differences between the studies. Our findings support the presence of a north-south gradient of MS prevalence in Sweden.

Work conditions, support, and changing personal priorities are perceived important for return to work and for stay at work after stroke - a qualitative study.

PURPOSE: To explore work related and personal facilitators and barriers for return to work (RTW) and stay at work after stroke. MATERIALS AND METHODS: Twenty individuals post-stroke (median age 52 years; seven women) were interviewed in focus groups. Data were analyzed by using qualitative content analysis. RESULTS: An overall theme "Work conditions, support and changed personal priorities influenced RTW and stay at work after stroke" emerged and covered three categories: "Adjustments and flexibility at the work place facilitated RTW and a sustainable work situation", "Psychosocial support and knowledge about stroke consequences facilitated work and reduced stress", and "Changed view of work and other personal priorities". Physical adjustments at the work place and flexibility in the work schedule were perceived facilitators. Support from family and colleagues were important, whereas lack of knowledge of stroke disabilities at the work place was perceived a barrier. Also changed personal priorities in relation to the work and the current life situation influenced RTW in various ways. CONCLUSIONS: The individual's opportunities to influence the work situation is a key factor for RTW and the ability to stay at work after stroke. Adjustments, flexibility, support, knowledge of stroke, and receptivity to a changed view of work are important for a sustainable work situation.Implications for rehabilitationPhysical adjustments at the work place, a flexible work schedule and support increase the individual's possibility to RTW and maintain a sustainable work situation after stroke.Changed work and life priorities after a stroke need attention in the RTW process.Rehabilitation professionals have an important role in providing knowledge about the disabilities following stroke, and how they impact work ability. Individually tailored recommendations for work place adjustments which enable RTW and a sustainable work situation are warranted.

Hospital admissions for ischemic stroke: does long-term exposure to air pollution interact with major risk factors?

BACKGROUND: The aim was to investigate whether the effects of major risk factors for ischemic stroke were modified by long-term exposure to air pollution in Scania, southern Sweden. METHODS: Cases were defined as first-ever ischemic strokes in patients born between 1923 and 1965 during 2001-2006 (n = 7,244). Data were collected from The Swedish National Stroke Register (Riks-stroke) and the Malmö and Lund Stroke Registers. Population controls were matched on age and sex. Modeled outdoor annual mean NO(x) concentrations were used as proxy for long-term exposure to air pollution. Heterogeneity across NO(x) categories was tested for smoking, hypertension, diabetes mellitus, atrial fibrillation and physical inactivity. Data were analyzed as case-control data and to some extent as case-only data, with logistic regression analysis. RESULTS: The case-control odds ratios for ischemic stroke in association with diabetes were 1.3 [95% confidence interval (CI): 1.1-1.6] and 2.0 (95% CI: 1.2-3.4) in the lowest and highest NO(x) category, respectively (p value for testing heterogeneity across the categories = 0.056). The case-only approach gave further support for the risk associated with diabetes to increase with NO(x) (p for trend = 0.033). We observed no main effect of mean NO(x) or any conclusive effect modifications between NO(x) and smoking, hypertension, atrial fibrillation or physical inactivity. CONCLUSIONS: In a low-level air pollution area, the risk for ischemic stroke associated with diabetes seemed to increase with long-term exposure to air pollution.

SENSory re-learning of the UPPer limb (SENSUPP) after stroke: development and description of a novel intervention using the TIDieR checklist.

BACKGROUND: Sensorimotor impairments of upper limb (UL) are common after stroke, leading to difficulty to use the UL in daily life. Even though many have sensory impairments in the UL, specific sensory training is often lacking in stroke rehabilitation. Thus, the aim of this paper is to provide a detailed description of the novel intervention "SENSory re-learning of the UPPer limb after stroke (SENSUPP)" that we have developed to improve functioning in the UL in persons with mild to moderate impairments after stroke. METHODS: The SENSUPP protocol was designed using information from literature reviews, clinical experience and through consultation of experts in the field. The protocol integrates learning principles based on current neurobiological knowledge and includes repetitive intensive practice, difficulty graded exercises, attentive exploration of a stimulus with focus on the sensory component, and task-specific training in meaningful activities that includes feedback. For reporting the SENSUPP protocol, the Template for Intervention Description and Replication (TIDieR) checklist was used. RESULTS: The essential features of the SENSUPP intervention comprise four components: applying learning principles based on current neurobiological knowledge, sensory re-learning (exercises for touch discrimination, proprioception and tactile object recognition), task-specific training in meaningful activities, and home-training. The training is performed twice a week, in 2.5-h sessions for 5 weeks. CONCLUSION: Since there is close interaction between the sensory and motor systems, the SENSUPP intervention may be a promising method to improve UL functioning after stroke. The TIDieR checklist has been very useful for reporting the procedure and development of the training. TRIAL REGISTRATION: ClinicalTrials.gov NCT03336749 . Registered on 8 November 2017.

Fatigue in men and women who have returned to work after stroke: Assessed with the Fatigue Severity Scale and Mental Fatigue Scale.

OBJECTIVE: To assess the occurrence of self-reported fatigue among men and women who have returned to work after stroke, and the association between 2 fatigue rating scales. DESIGN: A cross-sectional study. SUBJECTS: A total of 91 adults (58 men/33 women, mean age 53 years) with mild to moderate disability. METHODS: Questionnaires were posted to participants approximately one year after stroke. Fatigue was assessed with the Fatigue Severity Scale (FSS) and the Mental Fatigue Scale (MFS). RESULTS: In total, 58% of the women and 33% of the men reported fatigue on the FSS (total score ≥ 4), and 46% of the women and 28% of the men reported mental fatigue on the MFS (total score ≥ 10.5). Being easily fatigued, decreased motivation, mental fatigability and sensitivity to stress were the most reported problems. FSS and MFS were moderately associated (rho 0.517-0.732). CONCLUSION: Fatigue is common among persons who have returned to work after stroke, and interferes with daily life. The long-term consequences of fatigue should be addressed after stroke, especially in women. The FSS and the MFS can be used in combination, as they provide information on different aspects of fatigue.

Vestibular rehabilitation for persons with stroke and concomitant dizziness-a pilot study.

BACKGROUND: Dizziness is common among patients with first time stroke. It affects self-perceived health and is a risk factor for falls. Vestibular rehabilitation (VR) is effective for treating dizziness among various conditions, but the effect of dizziness with origin in the central nervous system is poorly studied.This pilot study of a randomized controlled trial aimed at investigating a vestibular rehabilitation programme among patients with first time stroke and concomitant dizziness. A second aim was to study the feasibility of performing the randomized controlled trial. METHODS: The participants were computer generated randomized to either an intervention or a control group. The intervention comprised of four different vestibular rehabilitation exercises, adapted for each patient and usual rehabilitation. The control group received usual rehabilitation without the vestibular rehabilitation exercises. Outcome measures used were The Activities-specific Balance Confidence Scale, the Berg Balance Scale, the Functional Gait Assessment Scale and the EuroQol-5D. Feasibility was studied in terms of recruitment, adherence and retention rates, also as the ability to collect primary and secondary outcomes as well as to find indications of treatment differences. RESULTS: Self-rated health improved for all participants. No other differences between baseline and follow-up were detected neither within nor between groups. Recruitment rate was 23%, adherence to the intervention 90%, retention rate 69% and ability to collect outcome measures 90%. No adverse events occurred. CONCLUSION: Both the intervention and the control groups improved in self-perceived health. The measures of feasibility were satisfactory in this study, apart from a low recruitment rate.
