Abstract
Ischemic stroke (IS) is often comorbid with type 2 diabetes mellitus (T2DM) wherein the determinants of long-term outcomes, beyond the acute stroke phase, are not adequately known. This study identified the determinants of long-term outcomes for diabetic IS patients through a prospective nested case-control study in 624 patients treated with conservative measures (38.60% females, mean age: 63.85 years). After 36-month follow-up, 117 (18.8%) patients with poor outcome were enrolled in the case group. The poor outcome was defined with a modified Rankin Scale (mRS) score ≥3. Meanwhile, 374 (59.9%) patients with good outcome, defined as (mRS score <3), were included in the control group. Patients who died (n = 32) or lost to follow-up (n = 101) were excluded in analysis. Poor prognostic outcome was positively associated with (1) the pulse rate at admission, (2) diastolic blood pressure (DBP), and (3) fasting blood glucose (FBG) during follow-up, whereas physical activity and lipid-lowering treatment during follow-up were negatively associated. Importantly, a forecasting model with these indicators distinguished the patients with good versus poor outcomes with 70.1% sensitivity and 73.5% specificity. Health care professionals and laboratory medicine scholars may want to monitor an increase in DBP and FBG during follow-up, as well as physical activity and lipid-lowering treatment, in relationship to the prognosis of IS with comorbid T2DM after conservative therapies. The proposed predictive model for personalized/precision medicine requires field testing in independent studies, and might help risk stratification with theranostic tests for patients with acute IS who also have a diagnosis of T2DM.

Abstract
Failure to diagnose transient ischemic attack (TIA) or stroke in a timely fashion is associated with significant patient morbidity and mortality. In the outpatient or clinic setting, we suspect that patients with minor, transient, and atypical manifestations of cerebrovascular disease are most prone to missed or delayed diagnosis. We therefore detail common stroke chameleon symptoms as well as atypical stroke presentations, broadly review new developments in the study of diagnostic error in the outpatient setting, suggest practical clinical strategies for diagnostic error reduction, and emphasize the need for rapid consultation of stroke specialists when appropriate. We also address the role of psychiatric disease and vascular risk factors in the diagnostic evaluation and treatment of suspected stroke/TIA patients. We advocate incorporating diagnostic time-outs into clinical practice to assure that the diagnosis of TIA or stroke is considered in all relevant patient encounters after a detailed history and examination are conducted in the outpatient setting.

Energy Cost During the 6-Minute Walk Test and Its Relationship to Real-World Walking After Stroke: A Correlational, Cross-Sectional Pilot Study. Phys Ther 2019; 99:1656-1666. [PMID: 31504975 DOI: 10.1093/ptj/pzz122] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Revised: 05/01/2018] [Accepted: 03/31/2019] [Indexed: 01/13/2023]
Abstract
BACKGROUND After experiencing stroke, individuals expend more energy walking than people who are healthy. However, among individuals who have experienced stroke, the correlation between the energy cost of walking, as measured by validated tests (such as the 6-minute walk test), and participation in walking, as measured by more sensitive tools (such as an ambulatory activity monitor), remains unknown. OBJECTIVE The main objective of this study was to determine whether the energy cost of walking is correlated with participation in walking. DESIGN This study was a correlational, cross-sectional pilot study. METHODS Data from 23 participants who had experienced chronic stroke were analyzed. On the first day, data on oxygen uptake were collected using a portable metabolic system while participants walked during the 6-minute walk test. Then, the ambulatory activity monitor was placed on the participants' nonparetic ankle and removed 9 days later. The energy cost of walking was calculated by dividing the mean oxygen uptake recorded during the steady state by the walking speed. RESULTS The energy cost of walking was correlated with the following: the number of steps (Spearman rank correlation coefficient [rs] = -0.59); the percentage of time spent in inactivity (rs = 0.48), low cadence (rs = 0.67), medium cadence (rs = -0.56), high cadence (rs = -0.65), and the percentages of steps taken at low cadence (rs = 0.65) and high cadence (rs = -0.64). LIMITATIONS Individuals who were physically inactive, convenience sampling, and a small sample size were used in this study. CONCLUSIONS Higher energy costs of walking were associated with fewer steps per day and lower cadence in real-world walking in individuals who had experienced stroke.

Abstract
Background Because genotype CG/GG of Furin rs2071410 can increase susceptibility to hypertension, this study investigated whether Furin rs2071410 is correlated with transient ischemic attack (TIA) susceptibility and prognosis. Material/Methods The odds ratios (ORs) and their 95% confidence intervals (95% CIs) were evaluated to assess the association of rs2071410 with TIA risk, and logistic regression was used to estimate the effects of various risk factors (e.g., diabetes, hypertension, and hyperlipidemia) on TIA. Results Compared with the homozygous genotype CC of rs2071410, the frequency of CG + GG genotype in the case group was significantly higher than in the control group (OR=1.47, 95% CI: 1.05–2.05, P<0.05). The CG + GG genotype carriers were observed to have worse 90-day prognosis after TIA treatment than patients carrying CC genotype (OR=12.86, 95% CI: 7.41–22.33, P<0.05). Moreover, logistic regression analysis found that age, diabetes, hypertension, and hyperlipidemia were associated with the onset of TIA (P<0.05, all). Of note, individuals with CG + GG genotype had 49.3% increased risk of TIA compared with individuals with CC genotype (OR=1.49, 95% CI: 1.05–2.12), and patients with CG + GG genotype had worse 90-day prognosis after TIA treatment than patients with CC genotype (OR=11.39, 95% CI: 6.29–20.62). Conclusions Furin rs2071410 was significantly correlated with TIA occurrence and prognosis in the Chinese population.

Abstract
The association between cerebral small vessel disease (SVD) - in the form of white matter lesions, infarctions, and hemorrhages - with vascular cognitive impairment (VCI), has mostly been deduced from observational studies. Pathological conditions affecting the small vessels of the brain and leading to SVD have suggested plausible molecular mechanisms involved in vascular damage and their impact on brain function. However, much still needs to be clarified in understanding the pathophysiology of VCI, the role of neurodegenerative processes such as Alzheimer's disease, and the impact of aging itself. In addition, both genetic predispositions and environmental exposures may potentiate the development of SVD and interact with normal aging to impact cognitive function and require further study. Advances in technology, in the analysis of genetic and epigenetic data, neuroimaging such as magnetic resonance imaging, and new biomarkers will help to clarify the complex factors leading to SVD and the expression of VCI.

Abstract
Background Perceived disability after stroke may persist long-term even among young individuals with mild stroke and may be related to age-related expectations of health and recovery. Thus, in order to appreciate the magnitude of perceived disability in a younger stroke population studies are needed to explore perceived health-related differences between young individuals with stroke and a matched general population. Further, to provide long-term measures by health care, relevant to the same young individuals with stroke, their perceived long-term functioning and disability associated with health need to be explored. Methods The generic questionnaire EQ-5D was used to compare ratings of global health and disability between young individuals living in the community up to 6 years after stroke (n = 150) and an age and geographically matched general population (n = 2661). Stroke related medical data were retrieved from medical records and the study specific questionnaire, the MYS-questionnaire, was used to assess self-rated disability associated with global health. Results Among the young individuals 79% had suffered a mild stroke, 45% rated a low global health compared to 15% of the matched general population and a higher proportion rated problems in mobility, self-care, usual activities and anxiety/depression. Among the young individuals with stroke, limitations and restrictions in leisure activities, work, reading as well as low level of physical activity, utilizing personal care provider or personal assistance and tiredness were negatively associated with self-rated global health (R square 0.60). Conclusion The negative effects of stroke, on self-rated global health among young individuals living in the community, appear to be substantial, multi factorial and long-standing which call for interdisciplinary research collaborations and team measures by health care long-term.

Abstract
BACKGROUND In the province of Saskatchewan, Canada, stroke is the third leading cause of death as well as the major cause of adult disability. Once a person suffers a stroke or transient ischemic attack (TIA), they are at high risk for having a secondary stroke. Hypertension (elevated blood pressure) is the single most important modifiable risk factor for both first and recurrent stroke, and is thus an important risk factor to be controlled. According to the Canadian Stroke Strategy (CSS) Best Practice Recommendations, blood pressure lowering treatment should be initiated before discharge from hospital for all stroke/TIA patients. The purpose of this study was to examine the quality of medically driven secondary stroke prevention care in Saskatchewan as applied to hypertension control. AIMS The objectives of the study were to: (1) develop methodology and calculate a secondary stroke process of care measure using available data in Saskatchewan, based on an appropriate hypertension therapy indicator recommendation from the CSS Performance Measurement Manual; (2) examine variation in secondary stroke prevention hypertensive care among the Saskatchewan Regional Health Authorities; and (3) investigate factors associated with receiving evidence-based hypertensive secondary stroke prevention. METHODS This multi-year cross-sectional study was an analysis of deidentified health data derived from linkage of administrative health data. A select indicator from the CSS Performance Measurement Manual that measures adherence to a CSS Best Practice Guidelines concerning use of antihypertensive medications for secondary stroke prevention was calculated. Logistic regression was used to quantify the association of patient demographic and socioeconomic characteristics and geographic location of care with receipt of guideline-recommended hypertensive secondary stroke prevention. The target population was all Saskatchewan residents who were hospitalized in Saskatchewan for a stroke or TIA between April 1, 2001 and March 31, 2008. RESULTS The results of this study indicate that the management of hypertension for secondary stroke prevention is sub-optimal in Saskatchewan. Although there was some improvement over the time period, approximately 40% of patients were not taking antihypertensives at 90 days after discharge from acute care. The correlates, urban/non-urban, previous use of antihypertensive drugs and effect of age modified by sex, were found to be significantly associated with receiving hypertensive secondary stroke prevention, suggesting there are modifiable factors that contribute to variations in this form of secondary stroke care quality in Saskatchewan. CONCLUSIONS The results of this study suggest that there is a need for province-wide improvement to secondary stroke prevention in Saskatchewan, Canada.

Abstract
A Fabry-kór a lizoszomális tárolási betegségek csoportjába tartozó, X-kromoszómához kötötten, recesszív módon öröklődő betegség, amely a globotriaozilceramid felhalmozódásához vezet a szervezet legkülönbözőbb szöveteiben. A betegség első tünetei többnyire gyermekkorban jelentkeznek, a progresszió során a betegek súlyos szervi károsodásokkal és korai halálozással számolhatnak. Elsősorban férfiak érintettek, azonban a betegség tüneteit heterozigóta nők esetében is megfigyelhetjük, de náluk a kórkép súlyossága változó, általában enyhébb lefolyású. Az enzimpótló kezelések megjelenése szükségessé tette, hogy részletes diagnosztikus és terápiás protokollt dolgozzunk ki. A jelen dolgozatban megjelenő ajánlásokat egy, a magyarországi Fabry-kóros betegek kezelésében részt vevő orvosokból, a diagnosztika területén dolgozó biológosukból és egyéb szakemberekből álló multidiszciplináris munkacsoport foglalta össze. A munkacsoport áttekintette a korábbi klinikai tanulmányokat, a publikált vizsgálatokat és a közelmúltban megjelent nemzetközi és nemzeti útmutatókat.

Abstract
BACKGROUND AND PURPOSE The aim of the study was to search for differences between clinical characteristics of recurrent ischaemic stroke which occurred within the fifth year after the first event or later, and early recurrence, i.e. within the first year after first-ever ischaemic stroke. We also tried to determine prognostic factors of late recurrent ischaemic episodes. MATERIAL AND METHODS The patients were divided into two groups: group I comprised 124 individuals with recurrence within the first year, and group II - 98 individuals in whom the recurrent episode appeared within the fifth year or later. RESULTS A significantly higher percentage of patients in group I demonstrated evident stenosis (70% or more) of internal carotid artery ipsilateral to stroke (p = 0.023). In this group more cardioembolic strokes were found compared to group II, while in the latter, predominantly lacunar strokes appeared (p = 0.046 and 0.0002, respectively). Group II patients significantly more frequently reported acetylsalicylic acid application, including systematic drug use (p = 0.001). No evident differences were found between groups considering other important non-modifiable and modifiable risk factors of stroke. CONCLUSIONS Small differences between risk factors of ischaemic stroke profiles in patients with early and late recurrent episodes do not allow us to distinguish unequivocally a group of patients with better prognosis regarding the time of recurrent stroke. Use of antiplatelet drugs, either systematic or non-systematic, and lacunar stroke are independent, positive prognostic factors of delay of potential recurrent stroke.

Abstract
A systematic review was conducted to investigate the use of technology in achieving behaviour change in chronic illness. The areas reviewed were: (1) methods employed to adapt traditional therapy from a face-to-face medium to a computer-assisted platform; (2) targets of behaviour change; and (3) level of human (e.g. therapist) involvement. The initial literature search produced 2032 articles. A total of 45 articles reporting 33 separate interventions met the inclusion/exclusion criteria and were reviewed in detail. The majority of interventions reported a theoretical basis, with many arising from a cognitive-behavioural framework. There was a wide range of therapy content. Therapist involvement was reported in 73% of the interventions. A common problem was high participant attrition, which may have been related to reduced levels of human interaction. Instigating successful behaviour change through technological interventions poses many difficulties. However, there are potential benefits of delivering therapy in this way. For people with long-term health conditions, technological self-management systems could provide a practical method of understanding and monitoring their condition, as well as therapeutic guidance to alter maladaptive behaviour.

Abstract
The variability in the behavioral outcome of human and nonhuman animals after stroke raises the question whether the way that a stroke occurs is a contributing factor. Photothrombotic stroke in rats has been reported to produce especially variable results, with some animals showing either slight to no impairment to other animals displaying severe impairments. The present study investigated this variability. Rats received three different-sized photothrombotic treatments and were contrasted to rats receiving a "standard" motor cortex stroke produced by pial stripping. Rats were assessed acutely and chronically on a skilled reaching for food task using end-point measures and movement assessment in a constraint-induced rehabilitation paradigm. The results indicated that as the size of the photothrombotic infarct approached the size of the pial strip infarct so did chronic behavioral deficits. Nevertheless there were differences in the time course of recovery. Rats with photothrombotic lesions of all sizes were less impaired in the acute period of recovery both on measures of learned nonuse and constrained-induced recovery. The findings are discussed in relation to the idea that whereas the course of recovery might be altered as a function of the type of stroke, chronic deficits are more closely related to the ensuing damage.
