The precision by the Face Arm Speech Time (FAST) algorithm in stroke capture, sex and age differences: a stroke registry study.

Background: The shift towards milder strokes and studies suggesting that stroke symptoms vary by age and sex may challenge the Face-Arm-Speech Time (FAST) coverage. We aimed to study the proportion of stroke cases admitted with FAST symptoms, sex and age differences in FAST presentation and explore any additional advantage of including new item(s) from the National Institute of Health Stroke Scale (NIHSS) to the FAST algorithm. Methods: This registry-based study included patients admitted with acute stroke to Sahlgrenska University Hospital (November 2014 to June 2019) with NIHSS items at admission. FAST symptoms were extracted from the NIHSS at admission, and sex and age differences were explored using descriptive statistics. Results: Of 5022 patients, 46% were women. Median NIHSS at admission for women was (2 (8-0) and for men 2 (7-0)). In total, 2972 (59%) had at least one FAST symptom, with no sex difference (p=0.22). No sex or age differences were found in FAST coverage when stratifying for stroke severity. 52% suffered mild strokes, whereas 30% had FAST symptoms. The most frequent focal NIHSS items not included in FAST were sensory (29%) and visual field (25%) and adding these or both in modified FAST algorithms led to a slight increase in strokes captured by the algorithms (59%-67%), without providing enhanced prognostic information. Conclusions: 60% had at least one FAST symptom at admission, only 30% in mild strokes, with no sex or age difference. Adding new items from the NIHSS to the FAST algorithm led only to a slight increase in strokes captured.

Symptoms, care consumption, and healthcare costs in hospitalized patients during the first wave of the COVID-19 pandemic.

BACKGROUND: We aimed to assess symptomatology post discharge from the hospital in patients with COVID-19 treated during the first wave of the COVID-19 pandemic, and to follow care consumption and healthcare costs six months post discharge. METHODS: This study was a descriptive observational study over time. Data were retrieved from the Sahlgrenska University (SU) hospital registry for patients admitted to an SU hospital during March 2020 to August 2020. Of these, 1014 received a questionnaire approximately six weeks post discharge regarding symptoms. Data regarding care consumption were retrieved from the registry in the Region Västra Götaland for 529 (52.2%) patients who completed the questionnaire. Of these, 466 patients were included in the analysis of care consumption. RESULTS: There was a reported decrease in mobility from admission to discharge in both men (p = 0.02) and women (p = 0.01). The costs of inpatient care amounted to a total of 9 601 459.20 Euro (EUR). Symptoms were reported in 436 (93.6%) patients post discharge, of which weight loss during COVID-19 was most common in both men (n = 220, 77.5%) and women (n = 107, 58.8%). During six-month follow-up, 409 (87%) patients consumed care. Of the registered visits, 868 (27.1%) were related to a COVID-19 diagnosis. The total sum of outpatient care (i.e. visits with a registered COVID-19 diagnosis) was 77 311.30 EUR. CONCLUSIONS: At discharge from the hospital, there was a decrease in mobility. Most patients had remaining sequelae post discharge. At six months post discharge, nearly 90% of patients had consumed care, with approximately 20% related to COVID-19. This indicates a persisting need for rehabilitation post discharge from hospital in patients treated for COVID-19.

Associations of Prestroke Physical Activity With Stroke Severity and Mortality After Intracerebral Hemorrhage Compared With Ischemic Stroke.

BACKGROUND AND OBJECTIVES: Prestroke physical activity may protect the brain from severe consequences of stroke. However, previous studies on this subject included mainly ischemic stroke cases, and the association between prestroke physical activity and outcomes after intracerebral hemorrhage is uncertain. Therefore, we sought to examine the associations between prestroke physical activity, stroke severity, and all-cause mortality after intracerebral hemorrhage in comparison with ischemic stroke. METHODS: This was a longitudinal, register-based cohort study. All adult patients with intracerebral hemorrhage or ischemic stroke admitted to 3 stroke units in Gothenburg, Sweden, between November 1, 2014, and June 30, 2019, were screened for inclusion. Physical activity was defined as light physical activity ≥4 h/wk or moderate physical activity ≥2 h/wk the year before stroke. Stroke severity was assessed on admission using the NIH Stroke Scale. All-cause mortality rates were followed up to 7 years, from the time of incident stroke until death or censoring. Ordinal logit models and Cox proportional hazards models were used to estimate adjusted associations of prestroke physical activity. RESULTS: We included 763 patients with intracerebral hemorrhage and 4,425 with ischemic stroke. Prestroke physical activity was associated with less severe strokes by an adjusted odds ratio of 3.57 (99% CI 2.35-5.47) for intracerebral hemorrhages and 1.92 (99% CI 1.59-2.33) for ischemic strokes. During a median follow-up of 4.7 (interquartile range 3.5-5.9) years, 48.5% of patients with intracerebral hemorrhage died, compared with 37.5% with ischemic stroke. Prestroke physical activity was associated with decreased short-term mortality (0-30 days) by an adjusted hazard ratio of 0.30 (99% CI 0.17-0.54) after intracerebral hemorrhage and 0.22 (99% CI 0.13-0.37) after ischemic stroke. Prestroke physical activity was further associated with decreased long-term mortality (30 days-2 years) by an adjusted hazard ratio of 0.40 (99% CI 0.21-0.77) after intracerebral hemorrhage and 0.49 (99% CI 0.38-0.62) after ischemic stroke. DISCUSSION: Prestroke physical activity was associated with decreased stroke severity and all-cause mortality after intracerebral hemorrhage and ischemic stroke, independent of other risk factors. Based on current knowledge, health care professionals should promote physical activity as part of primary stroke prevention.

Repeated Measures of Modified Rankin Scale Scores to Assess Functional Recovery From Stroke: AFFINITY Study Findings.

Background Function after acute stroke using the modified Rankin Scale (mRS) is usually assessed at a point in time. The analytical implications of serial mRS measurements to evaluate functional recovery over time is not completely understood. We compare repeated-measures and single-measure analyses of the mRS from a randomized clinical trial. Methods and Results Serial mRS data from AFFINITY (Assessment of Fluoxetine in Stroke Recovery), a double-blind placebo randomized clinical trial of fluoxetine following stroke (n=1280) were analyzed to identify demographic and clinical associations with functional recovery (reduction in mRS) over 12 months. Associations were identified using single-measure (day 365) and repeated-measures (days 28, 90, 180, and 365) partial proportional odds logistic regression. Ninety-five percent of participants experienced a reduction in mRS after 12 months. Functional recovery was associated with age at stroke <70 years; no prestroke history of diabetes, coronary heart disease, or ischemic stroke; prestroke history of depression, a relationship partner, living with others, independence, or paid employment; no fluoxetine intervention; ischemic stroke (compared with hemorrhagic); stroke treatment in Vietnam (compared with Australia or New Zealand); longer time since current stroke; and lower baseline National Institutes of Health Stroke Scale & Patient Health Questionnaire-9 scores. Direction of associations was largely concordant between single-measure and repeated-measures models. Association strength and variance was generally smaller in the repeated-measures model compared with the single-measure model. Conclusions Repeated-measures may improve trial precision in identifying trial associations and effects. Further repeated-measures stroke analyses are required to prove methodological value.

Patients' physical activity in stroke units in Latvia and Sweden.

OBJECTIVE: A prospective, observational study to describe levels of physical activity in patients with stroke in a comprehensive stroke unit in Sweden and Latvia, comparing data between countries. METHODS: The study was performed at stroke units in one hospital in Sweden (data were acquired over a 2-month period in 2017) and two hospitals in Latvia (data were acquired over a 3-month period between 2016 and 2017). Patients with stroke were observed for 1 min every 10 min. The level of physical activity, location, and the people present were noted at each time-point. RESULTS: A total of 27 patients were observed in Latvia and 25 patients in Sweden. Patients from both countries were in bed half of the time and spent the majority of the day in their bedroom and alone. Patients in Sweden had higher physical activity levels, spent more time outside their bedroom and spent more time with rehabilitation specialists and visitors. CONCLUSION: Patients are inactive and alone for a majority of the time during hospitalization at a comprehensive stroke unit in both countries. There are differences in environment in the stroke unit between countries.

A very long-term longitudinal follow-up of persons with late effects of polio.

BACKGROUND: As many as 60-80% of persons with a history of polio myelitis develop new symptoms, such as new or increased muscle weakness, muscle and joint pain, and fatigue several decades later, called postpolio syndrome (PPS). This may affect their ability to perform activities of daily living (ADL). It is still unclear if the patient's symptom is getting worse and in that case how much/fast the decline is. AIM: The aim of the present study was to evaluate long-term changes in disability in community dwelling patients with prior poliomyelitis, in contact with a polio clinic 14-16 years post their first assessment. DESIGN: A cross sectional longitudinal study. SETTING: Polio clinic. POPULATION: Fifty-two persons recruited from an earlier 4-year follow-up participated in the study. METHODS: A questionnaire was mailed prior to the visit at the polio clinic. Physical testing was performed by measuring muscle strength, walking speed and handgrip force. RESULTS: Overall there was a small change in muscle strength. A significant reduction in the right leg was found for flexion 60° and in dorsal flexion. For the left leg a significant reduction was found for plantar flexion. In the walking tests, a significant reduction was seen for spontaneous walking speed. No significant interaction between decrease in spontaneous walking speed and the variables age, BMI and flexion 60° and dorsal flexion in the right leg was seen. CONCLUSIONS: This cross-sectional longitudinal study shows small changes in muscle strength and disability. The results may imply that symptoms associated with late effects of polio are not progressing as fast as we had previously thought. CLINICAL REHABILITATION IMPACT: When health care professionals meet persons with late effects of polio the knowledge of long-term consequences of deterioration is important. Knowing that the deterioration is not as fast as previously thought, can help us to support the person in having a healthy lifestyle, stay active and encourage to perform adapted physical training.

NIHSS is not enough for cognitive screening in acute stroke: A cross-sectional, retrospective study.

The aim of this study was to investigate whether the cognitive subscale of the National Institute of Health Stroke Scale (NIHSS), the Cog-4, can detect cognitive deficits in acute stroke. This was a cross-sectional, retrospective study. The study sample consisted of people with stroke enrolled in an acute stroke unit. The index test Cog-4 was calculated based on admission NIHSS score. The reference standard instrument, the Montreal Cognitive Assessment (MoCA), was performed within 36-48 h of admission. Non-parametric statistics were used for data analyses. The study included 531 participants with a mean age of 69 years. The Cog-4 failed to identify cognitive deficits in 65%, 58%, and 53% of patients when the MoCA thresholds for impaired cognition were set at ≤25 p, ≤23 p, and ≤19 p, respectively, were chosen for impaired cognition. The agreement between the Cog-4 and the MoCA was poor; Cohen's kappa was from -0.210 to -0.109, depending on the MoCA cut-offs. The sensitivity of the Cog-4 was 35%, 42% and 48% for the MoCA thresholds for impaired cognition ≤25, ≤23 and ≤19 points, respectively. The Cog-4 has a limited ability to identify cognitive deficits in acute stroke. More structured and comprehensive tests should be employed as diagnostic tools.

Evidence-based position paper on Physical and Rehabilitation Medicine professional practice for persons with stroke. The European PRM position (UEMS PRM Section).

BACKGROUND: Stroke is a major cause of disability worldwide, with an expected rise of global burden in the next twenty years throughout Europe. This EBPP represents the official position of the European Union through the UEMS Physical and Rehabilitation Medicine (PRM) Section and designates the professional role of PRM physicians for people with stroke. The aim of this study is to improve PRM physicians' professional practice for persons with stroke in order to promote their functioning and enhance quality of life. METHODS: A systematic review of the literature including a ten-year period and a consensus procedure by means of a Delphi process has been performed involving the delegates of all European countries represented in the UEMS PRM Section. RESULTS: The systematic literature review is reported together with 78 recommendations resulting from the Delphi procedure. CONCLUSIONS: The professional role of PRM physicians for persons with stroke is to improve specialized rehabilitation services worldwide in different settings and to organize and manage the comprehensive rehabilitation programme for stroke survivors considering all impairments, comorbidities and complications, activity limitations and participation restrictions as well as personal and environmental factors.

Action Plan for Stroke in Europe 2018-2030.

Two previous pan-European consensus meetings, the 1995 and 2006 Helsingborg meetings, were convened to review the scientific evidence and the state of current services to identify priorities for research and development and to set targets for the development of stroke care for the decade to follow. Adhering to the same format, the European Stroke Organisation (ESO) prepared a European Stroke Action Plan (ESAP) for the years 2018 to 2030, in cooperation with the Stroke Alliance for Europe (SAFE). The ESAP included seven domains: primary prevention, organisation of stroke services, management of acute stroke, secondary prevention, rehabilitation, evaluation of stroke outcome and quality assessment and life after stroke. Research priorities for translational stroke research were also identified. Documents were prepared by a working group and were open to public comments. The final document was prepared after a workshop in Munich on 21-23 March 2018. Four overarching targets for 2030 were identified: (1) to reduce the absolute number of strokes in Europe by 10%, (2) to treat 90% or more of all patients with stroke in Europe in a dedicated stroke unit as the first level of care, (3) to have national plans for stroke encompassing the entire chain of care, (4) to fully implement national strategies for multisector public health interventions. Overall, 30 targets and 72 research priorities were identified for the seven domains. The ESAP provides a basic road map and sets targets for the implementation of evidence-based preventive actions and stroke services to 2030.

Quality of life in Swedish patients with post-polio syndrome with a focus on age and sex.

To investigate the health-related quality of life (QOL) in Swedish patients with post-polio syndrome (PPS), with a focus on sex and age. A total of 364 patients were recruited from five Swedish post-polio clinics. Analysis was carried out using SF-36 and data were compared with those of a normal population. QOL was significantly lower in PPS patients for all eight subdomains and the two main scores (physical compound score and mental compound score) when compared with the controls. Male patients had a significantly higher QOL than female patients for all subdomains and also for mental compound score and physical compound score, a phenomenon also observed in the normal population. There was a decrease in QOL in the physical domains and an increase in vitality with age. PPS decreases health-related QOL in both sexes, more in female patients. QOL for physical domains decreases whereas vitality increases with age in both sexes.

Is Pain Intensity Really That Important to Assess in Chronic Pain Patients? A Study Based on the Swedish Quality Registry for Pain Rehabilitation (SQRP).

BACKGROUND: Incorporating the patient's view on care and treatment has become increasingly important for health care. Patients describe the variety of consequences of their chronic pain conditions as significant pain intensity, depression, and anxiety. We hypothesised that intensities of common symptoms in chronic pain conditions carry important information that can be used to identify clinically relevant subgroups. This study has three aims: 1) to determine the importance of different symptoms with respect to participation and ill-health; 2) to identify subgroups based on data concerning important symptoms; and 3) to determine the secondary consequences for the identified subgroups with respect to participation and health factors. METHODS AND SUBJECTS: This study is based on a cohort of patients referred to a multidisciplinary pain centre at a university hospital (n = 4645, participation rate 88%) in Sweden. The patients answered a number of questionnaires concerning symptoms, participation, and health aspects as a part of the Swedish Quality Registry for Pain Rehabilitation (SQRP). RESULTS: Common symptoms (such as pain intensity, depression, and anxiety) in patients with chronic pain showed great variability across subjects and 60% of the cohort had normal values with respect to depressive and anxiety symptoms. Pain intensity more than psychological symptoms showed stronger relationships with participation and health. It was possible to identify subgroups based on pain intensity, depression, and anxiety. With respect to participation and health, high depressive symptomatology had greater negative consequences than high anxiety. CONCLUSIONS: Common symptoms (such as pain intensity and depressive and anxiety symptoms) in chronic pain conditions carry important information that can be used to identify clinically relevant subgroups.

Anxiety, depression, and psychological well-being 2 to 5 years poststroke.

OBJECTIVES: We sought to explore psychological well-being and the psychosocial situation in persons with stroke, 2 to 5 years after discharge from a specialized rehabilitation hospital. METHODS: The Hospital Anxiety and Depression Scale; the 30-item General Health Questionnaire; and a questionnaire were mailed to 255 former patients. RESULTS: A total of 64% answered (36% women), and the average age was 58 years. The Hospital Anxiety and Depression Scale identified problems in 47% (anxiety in 36% and depression in 28%) and 30-item General Health Questionnaire in 54%. About half had experienced periods of anxiety, depression, or both since discharge. Most were satisfied with support by family/friends (88%), home ward (68%), and community therapy services (57%). Marital status was as in the general population. CONCLUSIONS: Long after stroke, almost half of the investigated patients with stroke had psychiatric problems according to the questionnaires. This is higher than in the general population but is comparable with some other chronic, somatic populations in Norway.

Muscle strength in elderly adults with GH deficiency after 10 years of GH replacement.

CONTEXT: Only few studies have investigated the effects of GH replacement on muscle strength in elderly patients with GH deficiency (GHD). OBJECTIVE, DESIGN, AND PATIENTS: In this prospective open-labeled study, the effects of 10 years of GH replacement on muscle strength and neuromuscular function were followed in 24 elderly GHD adults (mean age of 65.2 years; range 61-74 years). Muscle strength was compared with reference values obtained from the background population. RESULTS: The mean initial GH dose of 0.72 mg/day was lowered to 0.37 mg/day. The mean IGF1 SDS increased from -1.10 at baseline to 1.17 at study end. GH replacement induced a sustained increase in lean body mass and a transient increase in isometric knee flexor strength. Isometric knee extensor strength was reduced after 10 years. However, after correction for age and gender, using observed/predicted value ratios, there was sustained and even progressive increase in most variables reflecting muscle strength. Measurements of neuromuscular function showed unchanged voluntary motor unit activation after 10 years. CONCLUSIONS: Ten years of GH replacement therapy in elderly GHD adults resulted in a transient increase in isometric knee flexor strength, and provided protection from most of the normal age-related decline in muscle performance and neuromuscular function.

Ten years of growth hormone (GH) replacement normalizes muscle strength in GH-deficient adults.

CONTEXT: GH replacement for 1-5 yr improves, but does not fully normalize, muscle strength. OBJECTIVE, DESIGN, AND PATIENTS: In this single-center, open-labeled, prospective study, the effects of 10 yr of GH replacement on muscle strength and neuromuscular function were followed in 109 consecutive adults (61 men; mean age 50.0 yr; range 22-74 yr) with adult-onset GH deficiency. RESULTS: The mean initial GH dose of 0.88 mg/d was gradually lowered to 0.47 mg/d. The mean IGF-I sd score increased from -1.54 at baseline to 1.12 at study end. GH replacement induced a sustained increase in lean mass and isometric knee flexor strength (60 degrees). In most other measures of upper leg and handgrip strength, there were transient increases during the first half of the study (0-5 yr), whereas during the second half (5-10 yr), the absolute values of muscle strength decreased and returned to or even below the baseline values. However, after correction for age and gender using observed/predicted value ratios, there were sustained and, until 7 yr, even progressive increases in the measures of muscle strength. At study end, knee flexor strength had increased to 104-110% of predicted, knee extensor strength to 93-108%, and handgrip strength to 88-93%. Measurements of neuromuscular function showed reduced voluntary motor unit activation after 10 yr. CONCLUSIONS: Ten years of GH replacement therapy increased muscle strength during the first half of the study and thereafter partly protected against the normal age-related decline in muscle strength and neuromuscular function, resulting in approximately normalized muscle strength after 10 yr.

Circuit training in community-living "younger" men after stroke.

OBJECTIVES: We sought to assess a training program focused on muscle strength and endurance in persons with prior stroke. METHODS: Thirty men with a slight hemiparesis caused by a first occurrence of stroke at least 6 months earlier were included with an average age of 54 years. The following was assessed before and after an 8-week period: muscle strength, endurance, work capacity, and activity level. The training group consisted of 21 persons and 9 served as control subjects. There were no differences between the groups in the various assessments from the start. The training was set up as circuit training with 5 stations aiming to strengthen the muscles and increase endurance in the bilateral lower limbs. The session lasted for 45 minutes, 3 times per week, for 8 weeks. On eligible persons in the training group, double-sided muscle biopsies were also performed before and after. RESULTS: There was significance in improved muscle strength and improved peak oxygen uptake for the paretic leg, which was reflected in the muscle enzymes. The nonparetic side also showed improvement, but to a lesser extent. The control group remained unchanged. CONCLUSIONS: Stroke survivors can improve muscle strength, endurance, and work capacity in both the paretic and nonparetic leg with a circuit training program.
