Knowledge Of Depression

Background: Stroke survivors are a higher risk for post-stroke depression (PSD) after they return home from the hospital. Given that many stroke patients have friends or family members (care partners) present after hospital discharge, this pilot study examined the utility of psychiatric nurses educating family members on how to recognize PSD. Methods: This pilot study identified stroke patients and their care partner while they were in the hospital, to provide education on depressive symptoms, community resources, safety resources (e.g., suicide hotline), how to address symptoms of depression with their care partner. A descriptive observational design was used wherein a psychiatric delivered PSD education to the patient’s care partner (instead of the patient). Knowledge of depression was assessed immediately prior to-, immediately after-, and at a 2-week follow-up after-, the education intervention. Results: This pilot study was not powered to detect a statistically significant difference. However, among the 20 subjects (mean age 61 years), fewer scores fell in the lower range (less knowledge of depression) immediately after the education and at the 2-week follow-up phone call. Conclusion: This study demonstrates the potential of multi-disciplinary nursing consultation to improve outcomes.

Tissue Plasminogen

Background: Intravenous Tissue Plasminogen Activator (TPA) is the only FDA approved medical therapy for acute ischemic stroke (AIS). Prior study suggests that early recanalization is associated with better stroke outcome. Our aim was to correlate task-negative and task-positive (TN/TP) resting state network activity with tissue perfusion and functional outcome, in stroke patients who received TPA. Method: AIS patients were consented and underwent NIH stroke scale (NIHSS) assessment and magnetic resonance imaging (MRI) scans during TPA infusion (baseline) and six hours post stroke. The MRI sequences include contrast-enhanced perfusion weighted image (PWI) and resting state Blood Oxygen Level-Dependent or BOLD (RSB) images acquired using a Siemens Treo 3T MRI scanner. Additionally, the RSB scan and the NIHSS were obtained at a 30-day follow up visit. Results: Fourteen patients (mean age ± SD=63 ±14, 50% male, 50% white, 43% black and 7% others) who qualified for TPA completed the study at baseline and 6 hours post stroke. Of these, 6 patients had valid follow up data at 30 days. Three patients without cerebral ischemia were excluded. A paired samples t-test comparing baseline and 6h post stroke showed a significantly improved TP network t(10)= -4.24 p< 0.05. The resting network connectivity improved from 6 hours post stroke to 30-days follow up, t(5)= -5.35 p< 0.01. Similarly, NIHSS, at 6h post stroke t(10)= 3.62 p< 0.01 and at 30-days follow up t(5)= -3.4 p< 0.01 were significantly better than the NIHSS at baseline. The 6-hours post-stroke perfusion correlated with the resting network connectivity in both the damaged (r=-0.56 p= 0.07) and intact hemispheres (r= -0.57 p= 0.06). Differences in functional connectivity and NIHSS scores from baseline to 6 h were positively correlated (r= 0.56 p=0.07). Conclusion: In this pilot study we found that TPA led to changes in MRI based resting state networks and associated functional outcome. Correlations were found between perfusion, functional connectivity and NIHSS. This suggests that the improvement of resting state network means improved efficiency of brain activity indicated by functional outcome and may be a potential predictive MRI biomarker for TPA response. A larger study is needed to verify this finding.

Diagnosis Of Dementia

ObjectiveStroke-survivors are at increased risk of future dementia. Assessment to identify those at high risk of developing a disease using predictive scores has been utilised in different areas of medicine. A number of risk assessment scores for dementia have been developed but none has been recommended for use clinically. The aim of this qualitative study was to assess the acceptability and feasibility of using a risk assessment tool to predict post-stroke dementia.DesignQualitative semi-structured interviews were conducted and analysed thematically. The patients and carers were offered interviews at around 6 (baseline) and 12 (follow-up) months post-stroke; clinicians were interviewed once.SettingThe study was conducted in the North-East of England with stroke patients, family carers and healthcare professionals in primary and secondary care.ParticipantsThirty-nine interviews were conducted (17 clinicians and 15 stroke patients and their carers at baseline. Twelve stroke patients and their carers were interviewed at follow-up, some interviews were conducted in pairs).ResultsBarriers and facilitators to risk assessment were discussed. For the patients and carers the focus for facilitators were based on the outcomes of risk assessment for example assistance with preparation, diagnosis and for reassurance. For clinicians, facilitators were focused on the process that is, familiarity in primary care, resource availability in secondary care and collaborative care. For barriers, both groups focused on the outcome including for example, the anxiety generated from a potential diagnosis of dementia. For the patients/carers a further barrier included concerns about how it may affect their recovery. For clinicians there were concerns about limited interventions and how it would be different from standard care.ConclusionsRisk assessment for dementia post-stroke presents challenges given the ramifications of a potential diagnosis of dementia. Attention needs to be given to how information is communicated and strategies developed to support the patients and carers if risk assessment is used.

Objective: We developed a footpad-type locomotion interface called the GaitMaster. The purpose of this pilot study was to examine the effects of gait rehabilitation using the GaitMaster in chronic stroke patients. Design: Randomized cross-over design. Setting: An outpatient department. Subjects: Twelve patients with chronic post-stroke hemiparesis. Intervention: In group A, patients underwent an ‘intervention phase’ followed by a ‘non-intervention phase’, whereas in group B, patients underwent the non-intervention phase first, followed by the intervention phase. In the four- or six-week intervention phase, participants underwent twelve 20-minute sessions of gait rehabilitation using the GaitMaster4. Main outcome measures: We measured gait speed and timed up-and-go test. Results: No differences between the two groups were observed in the baseline clinical data. For the combined groups A and B, the maximum gait and timed up-and-go test speeds improved significantly only in the intervention phase ( P = 0.0001 and P = 0.003, respectively). The percentages of improvement from baseline at the end of GaitMaster training were 16.6% for the maximum gait speed and 8.3% for the timed up-and-go test. The effect size for GaitMaster4 training was 0.58 on the maximum gait speed and 0.43 on the timed up-and-go test. Conclusions: This pilot study showed that gait rehabilitation using the GaitMaster4 was a feasible training method for chronic stroke patients. Calculation of the sample size indicated that a sample size of 38 participants would be adequate to test a null hypothesis of nil benefit additional to routine rehabilitation for chronic stroke patients in a future randomized controlled trial.

Introduction: Stroke is a serious health problem in the modern population. Spasticity is one of the consequences of stroke and affects about 30% of people. Increased muscle tone affects postural control disorders. Due to the specificity of spasticity, therapy in post-stroke patients is a challenge for neurological physiotherapy. Therefore, it requires the development of appropriate management standards . Study aim: The aim of the study was to evaluate the effectiveness of 3 combination therapy cycles based on botulinum toxin injection and physiotherapy for muscle tone, muscle strength and postural stability in post-stroke patients qualified for the spasticity treatment programme of the lower and upper limbs. Material and methods: The pilot study involved 12 patients (6 from the lower limb and 6 from the upper limb programme). The 1-year combination therapy programmes included 3 botulinum toxin injections and 3 weeks of physiotherapy after each injection. Clinical evaluation was conducted before and after the 1-year observation cycle. The results were evaluated using: MAS (Modified Ashworth Scale), MRC (Medical Research Council Scale) and posture stability test on a balance platform (BiodexSD). Results: A decrease was observed in muscle tone of the lower and upper limbs, as well as an increase in muscular strength of the upper limb. However, there were no noted statistical significance of the studied parameters. Conclusions: Physiotherapy in combination with the botulinum toxin is an important element of improvement in post-stroke patients. However, further research is needed to explicitly confirm its effectiveness.

Introduction: A modified platelet function test (mPFT) was recently found to be superior compared to impedance aggregometry for selection of post-stroke patients with high on-treatment platelet reactivity (HTPR). We aimed to explore some peripheral blood cell characteristics as predictors of recurrent ischemic episodes. The predictive value of mPFT was also assessed in a cohort followed up to 36 months regarding recurrent ischemic vascular events.Methods: As a novelty, not only whole blood (WB), but after 1-h gravity sedimentation the separated upper (UB) and lower half blood (LB) samples were analyzed including neutrophil antisedimentation rate (NAR) in 52 post-stroke patients taking clopidogrel. Area under the curve (AUC, AUCupper and AUClower, respectively) was separately measured by Multiplate in the WB, UB and LB samples to characterize ex vivo platelet aggregation in the presence of ADP. Next, the occurrence of vascular events (stroke, acute coronary syndrome, ACS) were evaluated during 36-month follow-up.Results: A total of 11 vascular events (stroke n = 5, ACS n = 6) occurred during the follow-up period. The AUCupper was significantly higher in patients with recurrent stroke compared to those with uneventful follow-up (p = 0.03). The AUCupper with a cut-off value ≥70 based on the mPFT, was able to predict all stroke events (p = 0.01), while the total vascular events were independently predicted by NAR with a sensitivity of 82% and specificity of 88%.Conclusions: A combination of NAR reflecting the inflammatory state and AUCupper indicating HTPR may provide a better prediction of recurrent ischemic events suggesting a better selection of patients at risk, thus providing an individually tailored vascular therapy.

Post Stroke Depression

Introduction: Post-stroke depression (PSD) occurs in approximately one-third of ischemic stroke patients. However, there is conflicting evidence on sex differences in PSD. Objective: We sought to assess sex differences in risk and time course of PSD in US ischemic stroke (IS) patients. We hypothesized that women are at greater risk of PSD than men, and that a greater proportion of women experience PSD in the acute post-stroke phase. Methods: Retrospective cohort study of 100% de-identified data for US Medicare beneficiaries ≥65 years admitted for ischemic stroke from July 1, 2016 to December 31, 2017. We calculated Kaplan-Meier unadjusted cumulative risk of depression, stratified by sex, up to 1.5 years following index admission. We performed Cox regression to report the hazard ratio (HR) for diagnosis of depression up to 1.5 years post-stroke in males vs. females, adjusting for patient demographics, comorbidities, length of stay, and acute stroke interventions. Results: Female stroke patients (n=90,474) were 20% more likely to develop PSD than males (n=84,427) in adjusted models. Cumulative risk of depression was consistently elevated for females throughout 1.5 years of follow-up (0.2055 [95% CI 0.2013-0.2097] vs. 0.1690 [95% CI 0.1639-0.1741] (log-rank p<0.0001). HR for PSD in females vs. males remained significant in fully adjusted analysis at 1.20 (95% CI 1.17-1.23, p<0.0001). Conclusions: Over 1.5 years of follow-up, female stroke patients had significantly greater hazard of developing PSD, highlighting the need for long-term depression screening in this population and further investigation of underlying reasons for sex differences.
