Comprehensive Stroke Care and Outcomes: Time for a Paradigm Shift

Stroke Rehabilitation and Motor Recovery

OBJECTIVE

Up to 50% of the nearly 800,000 patients who experience a new or recurrent stroke each year in the United States fail to achieve full independence afterward. More effective approaches to enhance motor recovery following stroke are needed. This article reviews the rehabilitative principles and strategies that can be used to maximize post-stroke recovery.

LATEST DEVELOPMENTS

Evidence dictates that mobilization should not begin prior to 24 hours following stroke, but detailed guidelines beyond this are lacking. Specific classes of potentially detrimental medications should be avoided in the early days poststroke. Patients with stroke who are unable to return home should be referred for evaluation to an inpatient rehabilitation facility. Research suggests that a substantial increase in both the dose and intensity of upper and lower extremity exercise is beneficial. A clinical trial supports vagus nerve stimulation as an adjunct to occupational therapy for motor recovery in the upper extremity. The data remain somewhat mixed as to whether robotics, transcranial magnetic stimulation, functional electrical stimulation, and transcranial direct current stimulation are better than dose-matched traditional exercise. No current drug therapy has been proven to augment exercise poststroke to enhance motor recovery.

ESSENTIAL POINTS

Neurologists will collaborate with rehabilitation professionals for several months following a patient's stroke. Many questions still remain about the ideal exercise regimen to maximize motor recovery in patients poststroke. The next several years will likely bring a host of new research studies exploring the latest strategies to enhance motor recovery using poststroke exercise.

β2-Microglobulin exacerbates neuroinflammation, brain damage, and cognitive impairment after stroke in rats

β2-Microglobulin (β2M), a component of the major histocompatibility complex class I molecule, is associated with aging-related cognitive impairment and Alzheimer's disease. Although upregulation of β2M is considered to be highly related to ischemic stroke, the specific role and underlying mechanistic action of β2M are poorly understood. In this study, we established a rat model of focal cerebral ischemia by occlusion of the middle cerebral artery. We found that β2M levels in the cerebral spinal fluid, serum, and brain tissue were significantly increased in the acute period but gradually decreased during the recovery period. RNA interference was used to inhibit β2M expression in the acute period of cerebral stroke. Tissue staining with 2,3,5-triphenyltetrazolium chloride and evaluation of cognitive function using the Morris water maze test demonstrated that decreased β2M expression in the ischemic penumbra reduced infarct volume and alleviated cognitive deficits, respectively. Notably, glial cell, caspase-1 (p20), and Nod-like receptor pyrin domain containing 3 (NLRP3) inflammasome activation as well as production of the inflammatory cytokines interleukin-1β, interleukin-6, and tumor necrosis factor-α were also effectively inhibited by β2M silencing. These findings suggest that β2M participates in brain injury and cognitive impairment in a rat model of ischemic stroke through activation of neuroinflammation associated with the NLRP3 inflammasome.

Green tea consumption and the risk of stroke: A systematic review and meta-analysis of cohort studies

OBJECTIVES

Epidemiologic studies are inconsistent regarding the association between green tea consumption and the risk of stroke. We performed a meta-analysis to determine whether an association exists between them in cohort studies.

METHODS

We searched the PubMed and Embase databases for studies conducted from 1966 through September 2022. Prospective cohort studies that provided relative risk (RR) estimates with 95% confidence interval (CI)s for the association were included. Study-specific risk estimates were combined by using a random-effects model.

RESULTS

A total of five studies, with 11 421 stroke cases among 645 393 participants, were included in the meta-analysis. The summary RR indicated a significant association between highest green tea consumption and reduced risk of stroke (summary RR: 0.74; 95% CI, 0.66-0.83). In the dose-response analysis, we observed a nonlinear association between green tea consumption and the risk of stroke (P for nonlinearity = 0.0000). Compared with non-consumers, the RRs (95% CI) of stroke across levels of green tea consumption were 0.91 (0.89-0.94) for 150 mL/d, 0.84 (0.80-0.89) for 300 mL/d, 0.79 (0.74-0.84) for 500 mL/d, 0.77 (0.72-0.82) for 900 mL/d, and 0.84 (0.77-0.91) for 1500 mL/d.

CONCLUSIONS

This meta-analysis suggests that green tea consumption is inversely associated with the risk of stroke, especially among those with moderate consumption. Our results support recommendations for green tea consumption to the primary prevention of stroke.

A Unified Model for Stroke Recovery and Rehabilitation: Why Now?

ABSTRACT

The current model of stroke care delivery in the United States and in many parts of the world is fragmented, resulting in lack of continuity of care, inability to track recovery meaningfully across the continuum, and lack of access to the frequency, intensity, and duration of high-quality rehabilitation necessary to optimally harness recovery processes. The process of recovery itself has been overshadowed by a focus on length of stay and the movement of patients across levels of care. Here, we describe the rationale behind the recent efforts at the Johns Hopkins Sheikh Khalifa Stroke Institute to define and coordinate an intensive, strategic effort to develop effective stroke systems of care across the continuum through the development of a unified Sheikh Khalifa Stroke Institute model of recovery and rehabilitation.

Feasibility of an Enhanced Therapy Model of Care for Hospitalized Stroke Patients

INTRODUCTION

The aim of this study was to determine the safety and feasibility of an enhanced therapy model for hospitalized stroke patients.

METHODS

This was a quasi-experimental cohort study of acute stroke patients from a single hospital. In the intervention group, all hospitalized patients on the acute stroke service were seen by at least two therapy disciplines daily in addition to routine stroke care. The comparison group consisted of all patients admitted to the same stroke service 1 year before who received the standard of care. The primary endpoint was the number of completed therapy sessions. Exploratory endpoints compared the length of hospital stay, hospital readmission rates, and degree of disability measured by the 90-day modified Rankin Scale score.

RESULTS

A total of 1110 records were analyzed with 553 subjects in the intervention group and 557 in the control group. The intervention group received a significantly higher number of therapy sessions. There was no significant difference in length of hospital stay. However, 30-day readmission rates were lower, and the percentage of patients who achieved a good functional outcome on the modified Rankin Scale was higher during the intervention period.

CONCLUSION

Increasing exposure to intensive multidisciplinary therapy comparable with that of acute inpatient rehabilitation in the hospital setting is feasible and may reduce both readmission rates and disability.

Bringing High-Dose Neurorestorative Behavioral Training Into the Acute Stroke Unit

ABSTRACT

Stroke remains common and is a leading cause of adult disability. While there have been enormous system changes for the diagnosis and delivery of hyperacute stroke treatments at comprehensive stroke centers, few advances have been made in those same centers for treatments focused on behavioral recovery and brain repair. Specifically, during the early hospital period, there is a paucity of approaches available for reduction of impairment beyond what is expected from spontaneous biological recovery. Thus, patients in the early stroke recovery period are not receiving the kind of training needed, at the requisite intensity and dose, to exploit a potential critical period of heightened brain plasticity that could maximize true recovery instead of just compensation. Here, we describe an ongoing pilot program to reconfigure the acute stroke unit experience to allow for a new emphasis on brain repair. More specifically, we have introduced a novel room-based video-gaming intervention; restorative neuroanimation, into the acute stroke hospital setting. This new intervention provides the opportunity for an extra hour(s) of high-intensity neurorestorative behavioral treatment that is complementary to conventional rehabilitation. To accomplish this, system redesign was required to insert this new treatment into the patient day, to properly stratify patients behaviorally and physiologically for the treatment, to optimize the digital therapeutic approach itself, and to maintain the impairment reduction after discharge.

Comparison of TBI and CVA outcomes: Durability of gains following post-hospital neurological rehabilitation

BACKGROUND

With the effectiveness of post-hospital brain injury rehabilitation clearly demonstrated, research focus has shifted to durability of treatment gains over time.

OBJECTIVE

Study objectives were threefold: (1) examined the stability of outcomes following post-hospital rehabilitation for persons with acquired brain injury, (2) compare differences in short and long-term outcome for TBI and CVA groups, and (3) identify predictors of long-term outcomes.

METHODS

Subjects (n = 108) were selected from 2,177 neurologically impaired adults with consecutive discharges from 18 post-hospital programs in 12 states from 2011 through 2019. The study sample included TBI, CVA, and Mixed neurological groups. All persons were evaluated using the Mayo Portland Adaptability Inventory -4 Participation Index at four assessment intervals: admission, discharge, and 3 and 12 month follow-up. Additional analyses included repeated measures 2x4 design addressing TBI and CVA by the four measurement periods, and hierarchical multiple regression to identify outcome predictors.

RESULTS

The total sample demonstrated a reduction in Participation T-scores (indicating less disability) from admission to discharge. Reductions in disability were maintained at the 3 and 12 month follow-up assessments (Greenhouse-Geisser F (2.37) = 76.87, p < 0.001, partial eta2 = 0.418, power to detect = 0.99). The CVA group demonstrated greater disability at each assessment interval, however, those differences were not statistically significant. Significant predictors of outcome at 12 months post-discharge were length of stay in program and type of injury. TBIs with longer length of stay experienced better outcome at 12 months than non-TBIs with shorter length of stays (hierarchical multiple regression adjusted R2 = 0.085, p < 0.05).

CONCLUSION

Post-hospital residential neurorehabilitation programs provide a return on investment. Gains are realized from admission to discharge, and maintained one year following discharge from rehabilitation.

A meta-analysis of studies of the effects of case management intervention for stroke survivors across three countries

PURPOSE

A stroke survivor who is discharged to home care faces many challenges during the transition from the hospital to home, including managing their care at home and engaging in rehabilitation and recovery. Case management was developed to ease the transition from hospital to home and help people with stroke cope with their care management challenges. However, the effects of case management intervention remain inconclusive. Case management was designed to direct care and may represent a novel method for reducing the burden of care. This study was designed to evaluate the effects of case management interventions on mental health outcomes, activities of daily living capacity, physical function, and social function among stroke survivors.

DESIGN

Systematic review and meta-analysis.

METHODS

This study included studies examining the impacts of case management interventions for stroke survivors that were published in English and identified by searching eight databases, from database inception to February 20, 2022. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were used to pool effect sizes using a random-effects model (in Stata 16.0). The revised Cochrane risk-of-bias tool for randomized trials (RoB-2) was used to assess the methodological quality of each study.

FINDINGS

The inclusion criteria were satisfied by eight studies (including a total of 1119 stroke survivors). Case management had positive effects on mental health (SMD: 0.26; 95% CI: 0.07 to 0.45, p = 0.001) and activities of daily living (SMD: 0.68; 95% CI: 00.37 to 0.99, p < 0.001). However, no significant effects were observed for either physical function or social function.

CONCLUSION

Case management appears to enhance the mental health and activities of daily living among stroke survivors.

CLINICAL RELEVANCE

Case management interventions hold promise as efficient, cost-effective, and accessible strategies to positively influence care for stroke survivors. This intervention strategy could be applied to the hospital-to-home transition to guide care among this population.

Updates in mechanical thrombectomy

Stroke is a leading cause of morbidity and mortality. The advent of mechanical thrombectomy has largely improved patient outcomes. This article reviews the features and outcomes associated with aspiration, stent retrievers, and combination catheters used in current practice. There is also a discussion on clinical considerations based on anatomical features and clot composition. The reperfusion grading scale and outcome metrics commonly used following thrombectomy when a patient is still in the hospital are reviewed. Lastly, there are proposed discharge and outpatient follow-up goals in caring for patients hospitalized for a stroke.

Gut microbiota signature as predictors of adverse outcomes after acute ischemic stroke in patients with hyperlipidemia

Introduction

The alterations of gut microbiota have been associated with multiple diseases. However, the relationship between gut microbiota and adverse outcomes of hyperlipidemic stroke patients remains unclear. Here we determined the gut microbial signature to predict the poor outcome of acute ischemic stroke (AIS) with hyperlipidemia (POAH).

Methods

Fecal samples from hyperlipidemic stroke patients were collected, which further analyzed by 16s rRNA gene sequencing. The diversity, community composition and differential gut microbiota were evaluated. The adverse outcomes were determined by modified Rankin Scale (mRS) scores at 3 months after admission. The diagnostic performance of microbial characteristics in predicting adverse outcomes was assessed by receiver operating characteristic (ROC) curves.

Results

Our results showed that the composition and structure of gut microbiota between POAH patients and good outcome of AIS with hyperlipidemia (GOAH) patients were different. The characteristic gut microbiota of POAH patients was that the relative abundance of Enterococcaceae and Enterococcus were increased, while the relative abundance of Lachnospiraceae, Faecalibacterium, Rothia and Butyricicoccus were decreased. Moreover, the characteristic gut microbiota were correlated with many clinical parameters, such as National Institutes of Health Stroke Scale (NIHSS) score, mean arterial pressure, and history of cerebrovascular disease. Moreover, the ROC models based on the characteristic microbiota or the combination of characteristic microbiota with independent risk factors could distinguish POAH patients and GOAH patients (area under curve is 0.694 and 0.971 respectively).

Conclusions

These findings revealed the microbial characteristics of POAH, which highlighted the predictive capability of characteristic microbiota in POAH patients.

Effects of the nurse-led program on disabilities improvement in patients with ischemic stroke

To evaluate whether the nurse-led program can improve disabilities in patients with ischemic stroke for more than 6 months. This is a randomized, open-label study. Participants in the usual-care group received the usual care that included verbal stroke-related education and secondary prevention. Participants in the active group received the usual care plus the nurse-led program intervention. The disability was evaluated using National Institutes of Health Stroke Scale (NIHSS). The Mental Health Inventory-5 (MHI-5) was used to assess mental health status (MHS). The median duration since ischemic stroke was 8.4 and 8.6 months, respectively. At baseline, there was no difference in the median NIHSS value and the NIHSS category between these 2 groups. After 6 months' follow-up, the median NIHSS value was lower in the active group (4.1 vs 6.3). The proportion of patients with NIHSS of 1 to 4 was higher (50.0% vs 28.6%) while the proportion of patients with NIHSS of 5 to 12 (24.1% vs 51.8%) was lower in the active group. After multivariate regression analysis, the nurse-led program was negatively associated with increased NIHSS category (odds ratio of 0.70 and 95% confidence interval of 0.62-0.88). In the group with MHI-5 less than median, the nurse-led program was not associated with NIHSS category. While in the group with MHI-5 greater than median, the nurse-led program was associated decreased NIHSS category, with a significant interaction (P value = .03). In ischemic stroke patients for more than 6 months, the nurse-led program improves disabilities, which might be related to MHS improvement.

Plasmatic trimethylamine N-oxide and its relation to stroke: A systematic review and dose-response meta-analysis

BACKGROUND

Elevated circulating concentrations of the gut metabolite, trimethylamine N-oxide (TMAO), were found in patients who experienced stroke. However, it has not been reported whether a high level of TMAO is associated with a significantly increased risk of stroke. This study aimed to review the available scientific evidence about the relationship between TMAO levels and the risk of stroke in a dose-response meta-analysis.

METHODS

The PubMed, Embase, Cochrane library, and China National Knowledge Infrastructure databases were searched for studies starting from September 1996 to December 2020. Nine studies including 4402 subjects were reviewed in this study.

RESULTS

The results of meta-analysis showed that high levels of circulating TMAO were associated with an increased risk of stroke in patients in the random-effects model (odds ratio [OR], 1.64; 95% confidence interval [CI], 1.12-2.41; P = 0.047). The OR for the prevalence of stroke increased by 48% per 5-μmol/L increment (OR, 1.05; 95% CI, 1.16-1.78; P < 0.001) and by 132% per 10-μmol/L increment (OR, 2.32; 95% CI, 1.38-3.86; P < 0.001) in circulating TMAO concentration according to the dose-response meta-analysis.

CONCLUSION

There was a significant association between higher plasma TMAO concentrations and the risk of stroke. Further in-depth studies are warranted to validate this interaction and explore potential mechanisms.

Observation of the Effect of TTM-Based Health Information Behavior Combined with Continuous Nursing on Cognitive and Motor Function, Living Ability, and the Quality of Life of Cerebral Stroke Patients

Purpose

To discuss the effect of the transtheoretical model (TTM) of behavior-based health information behavior combined with continuous nursing on cognitive function, motor function, living ability, and quality of life of cerebral stroke (CS) patients.

Methods

540 cases of CS patients hospitalized in our hospital from June 2020 to June 2021 were selected. All the subjects were divided into the control group (270 cases) and study group (270 cases) according to the random number table. The control group was given routine nursing intervention and the study group was given TTM-based health information behavior combined with continuous nursing. The patients were paid a return visit 6 months after discharge, and their cognitive function, motor function, living ability, and quality of life were observed before and after intervention.

Results

After intervention, the Montreal cognitive assessment scale score, Fugl-Meyer assessment of motor function score, Barthel index score, and short health scale score of both groups were higher than before intervention, and the study group was higher than the control group (P < 0.05).

Conclusion

TTM-based health information behavior combined with continuous nursing has a significant positive impact on cognitive function, motor function, living ability, and quality of life of CS patients.

Targeted delivery of fat extract by platelet membrane-cloaked nanocarriers for the treatment of ischemic stroke

BACKGROUND

Our previous studies suggest that human fat extract (FE) contains a variety of angiogenic factors and may provide an alternative treatment option for stroke. However, the therapeutic effect is largely limited due to its short half-life, and inaccurate targeting.

RESULTS

Herein, we leverage the targeting abilities of platelets (PLTs) to the lesion area of stroke and Arg-Gly-Asp (RGD) peptides to the angiogenic blood vessels to develop a biomimetic nanocarrier that capable of delivering FE precisely to treat stroke. The biomimetic nanocarriers are comprised of FE-encapsulated PLGA (poly(lactic-co-glycolic acid)) core enclosed by RGD peptides decorated plasma membrane of PLTs, namely RGD-PLT@PLGA-FE. We found that RGD-PLT@PLGA-FE not only targeted damaged and inflamed blood vessels but also achieved rapid accumulation in the lesion area of ischemic brain. In addition, RGD-PLT@PLGA-FE kept a sustained release behavior of FE at the lesion site, effectively increased its half-life and promoted angiogenesis and neurogenesis with delivering neurotrophic factors including BDNF, GDNF and bFGF to the brain, that ultimately resulted in blood flow increase and neurobehavioral recovery.

CONCLUSIONS

In conclusion, our study provides a new strategy to design a biomimetic system for FE delivery and it is a promising modality for stroke therapy.

Development of a Brain-Computer Interface-Based Symbol Digit Modalities Test and Validation in Healthy Elderly Volunteers and Stroke Patients

Standard cognitive assessment tools often involve motor or verbal responses, making them impossible for severely motor-disabled individuals. Brain-computer interfaces (BCIs) are expected to help severely motor-impaired individuals to perform cognitive assessment because BCIs can circumvent motor and verbal requirements. Currently, the field of research to develop cognitive tasks based on BCI is still in its nascent stage and needs further development. This study explored the possibility of developing a BCI version of symbol digit modalities test (BCI-SDMT). Steady-state visual evoked potential (SSVEP) was adopted to build the BCI and a 9-target SSVEP-BCI was realized to send examinees' responses. A training-free algorithm (i.e., filter bank canonical correlation analysis) was used for SSVEP identification. Thus, examinees are able to start the proposed BCI-SDMT immediately. Eighty-nine healthy elderly volunteers and 9 stroke patients were enrolled to validate the technical feasibility of the developed BCI-SDMT. For all participants, the average recognition accuracies of the developed BCI and BCI-SDMT were 93.89 ± 8.48% and 92.58 ± 10.52%, respectively, were considerably above the chance level (i.e., 11.11%). These results indicated that both healthy elderly volunteers and stroke patients could elicit sufficient SSVEPs to control the BCI. Furthermore, patient use of the developed BCI-SDMT was unaffected by the presence of motor impairment. They could understand instructions, pair numbers with specific symbols, and send commands using the BCI. The proposed BCI-SDMT can be used as a complement to the existing versions of the SDMT and has the potential to evaluate cognitive abilities in individuals with severe motor disabilities.

Stroke Related Knowledge, Prevention Practices and Associated Factors Among Hypertensive Patients at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, 2021

Introduction

Stroke is a global health problem, causing significant morbidities and mortalities in both developing and developed countries. Patients living with chronic diseases like hypertension are at a high risk of stroke. Approximately 80% of strokes could be prevented with necessary preventive practices. There is scarce evidence in the preventive practices in Ethiopia, particularly in the study area. Therefore, this study aimed to assess knowledge and prevention practices related to stroke among hypertensive patients at the University of Gondar comprehensive specialized hospital, northwest Ethiopia.

Methods

An institution-based cross-sectional study was conducted among 393 hypertensive patients at the University of Gondar Comprehensive Specialized Hospital from May 1st to June 30th, 2021. The study participants were selected by a systematic random sampling technique. A semi-structured and interviewer-administered questionnaire was used to collect data. The data was entered into EPI Info version 7.2.1 and analyzed with SPSS version 23.0. Binary logistic regression analyses were undertaken to identify associated factors. The level of significance was determined using the adjusted odds ratio (AOR) with its 95% CI at a p-value of 0.05.

Results

Participants in this study had adequate knowledge of stroke and good prevention practices in 40.7% (95% CI: 35.9, 45.5) and 51.7% (95 CI: 46.8, 56.5) of cases, respectively. Attending secondary education and above 4.6 (95% CI: 2.08, 10.17), knowing someone who has had a stroke 13.17 (95% CI: 7.3, 23.77), and physical activity 4.05 (95% CI: 2.23, 7.36) were all significantly associated with adequate stroke knowledge. Furthermore, educational status (attending primary education 2.61 (95% CI: 1.44, 4.73) and secondary education and above 3.75 (95% CI: 1.99, 7.05), being an urban dweller 9.65 (95% CI: 5.04, 18.44), duration of hypertension 1.9 (95% CI: 1.15, 3.14), knowing someone with a stroke 2.27 (95% CI: 1.30, 3.93), and physical activity 1.76 (95% CI: 1.03, 3.01) were associated with good stroke prevention practices.

Conclusion

The proportion of participants with good-related knowledge and prevention practice is relatively good.

A Scoping Review of Non-Pharmacological, Non-Surgical Secondary Prevention Strategies in Ischaemic Stroke and TIA in National Stroke Guidelines and Clinical Audit Documents

The Stroke Action Plan for Europe (2018-2030) calls for national-level secondary prevention plans that address lifestyle, in addition to prevention medications and surgical interventions. This scoping review examines national stroke care guideline and audit documents across WHO regions to identify non-pharmacological, non-surgical stroke secondary prevention recommendations and associated performance indicators. Using a snowballing methodology, 27 guideline documents met the inclusion criteria. Sixteen (59%) detailed, non-pharmacological, non-surgical stroke secondary prevention-addressing known, modifiable population attributable risk factors, of physical inactivity (N = 11), smoking (N = 11), unsafe alcohol consumption (N = 10), diet (N = 8), weight (N = 5), stress (N = 4) and depression (N = 2). Strategies recommended to address these risk factors were: assessment of stroke risk/risk factors (N = 4); provision of advice and information on reducing lifestyle related risk (N = 16); education and counselling for lifestyle behaviour change (N = 8) and onward referral for specialist management of risk (N = 4). Of the nine stroke audits/registries identified, only three (33%) included non-pharmacological, non-surgical quality indicators of documented provision of advice or information on the following: general lifestyle (N = 2); smoking cessation for current smokers (N = 2); reduction in alcohol consumption, where relevant (N = 1), exercise participation (N = 1) and diet (N = 1). Preventive quality indicators addressing the management of weight, stress or depression were absent. This review highlights current gaps in optimal stroke secondary prevention recommendations and their implementation.

[Functional and activity limitations in patients after a stroke]

One of the main characteristics of the goal of rehabilitation after a stroke is the focus on restoring a certain level of functioning. The formation of the goal of rehabilitation and the implementation of effective rehabilitation are possible when taking into account not only the clinical diagnosis, but also the problems and possibilities of the patient in the categories of the International Classification of Functioning, Disabilities and Health (ICF).

PURPOSE OF THE STUDY

To assess the types and degree of functional limitations and activity limitations in patients after ischemic and hemorrhagic strokes in the early recovery period, taking into account the type of stroke and the affected vascular pool.

MATERIAL AND METHODS

528 patients after a stroke were examined. Functional limitations and activity limitations were assessed in ICF categories, taking into account the type of stroke (hemorrhagic, ischemic) and the affected vascular system (carotid, vertebrobasilar), including dysfunctions (motor, global and specific mental functions, balance function, functions of the cardiovascular system), activity restrictions (limitations of paretic limbs mobility, functional independence from others). To quantify the degree of limitation, generally accepted rating scales were used (Medical Research Council Scale, Modified Ashworth Scale of muscle spasticity, Frenchay arm test, Hauser ambulation index, Rivermead mobility index, Functional Independence Measure, «Memory for images», «Learning 10 words», «Red-black Schulte-Platonov tables», Luscher color test, The hospital Anxiety and Depression Scale, Recovery Locus of Control), stabilography method, registration of office and outpatient blood pressure.

RESULTS

Limitations of the functions of paretic limbs and activity associated with maintaining body position, walking, movement, transfer, manipulation of objects and self-care, dependence on others in everyday life were found in most patients after hemorrhagic stroke (in 94-95%) and ischemic (in 88-93%) stroke in the carotid pool, while more severe disorders were recorded in cases of hemorrhagic type of stroke. Violation of global mental functions was recorded in ¼ of patients, specific mental functions - in 60-75% of patients after hemorrhagic stroke and ischemic stroke in the carotid pool. In ischemic stroke happens in the vertebrobasilar basin, the limitations of the daily activity of patients were determined by the violation of static and dynamic balance; a mild degree of impairment of specific mental functions and limitation of activity (self-service) were also recorded.

CONCLUSION

After a stroke, motor function disorders, mobility limitations of paretic limbs and self-service, postural disorders are recorded. After an ischemic stroke in the vertebrobasilar basin, the restrictions on the activity of patients are determined by postural disorders. Taking into account the identified features of functional limitations and activity limitations in patients after a stroke will allow developing a differentiated approach not only to the formation of goals and objectives of rehabilitation, but also to the choice of rehabilitation methods.

Predictive Value of CT Perfusion Imaging on the Basis of Automatic Segmentation Algorithm to Evaluate the Collateral Blood Flow Status on the Outcome of Reperfusion Therapy for Ischemic Stroke

Our objective was to study the predictive value of CT perfusion imaging based on automatic segmentation algorithm for evaluating collateral blood flow status in the outcome of reperfusion therapy for ischemic stroke. All data of 30 patients with ischemic stroke reperfusion in our hospital were collected and examined by CT perfusion imaging. Convolutional neural network (CNN) algorithm was used to segment perfusion imaging map and evaluate the results. The patients were grouped by regional leptomeningeal collateral score (rLMCs). Binary logistic regression was used to analyze the independent influencing factors of collateral blood flow on brain CT perfusion. The modified Scandinavian Stroke Scale was used to evaluate the prognosis of patients, and the effects of different collateral flow conditions on prognosis were obtained. The accuracy of CNN segmentation image is 62.61%, the sensitivity is 87.42%, the similarity coefficient is 93.76%, and the segmentation result quality is higher. Blood glucose (95% CI = 0.943, P=0.028) and ischemic stroke history (95% CI = 0.855, P=0.003) were independent factors affecting the collateral blood flow status of stroke patients. CBF (95% CI = 0.818, P=0.008) and CBV (95% CI = 0.796, P=0.016) were independent influencing factors of CT perfusion parameters. After 3 weeks of onset, the prognostic function defect score of the good collateral flow group (11.11%) was lower than that of the poor group (41.67%) (P < 0.05). The automatic segmentation algorithm has more accurate segmentation ability for stroke CT perfusion imaging and plays a good auxiliary role in the diagnosis of clinical stroke reperfusion therapy. The collateral blood flow state based on CT perfusion imaging is helpful to predict the treatment outcome of patients with ischemic stroke and further predict the prognosis of patients.

Nursing's Role in Successful Stroke Care Transitions Across the Continuum: From Acute Care Into the Community

Facilitating successful care transitions across settings is a key nursing competency. Although we have achieved improvements in acute stroke care, similar advances in stroke care transitions in the postacute and return to community phases have lagged far behind. In the current delivery system, care transitions are often ineffective and inefficient resulting in unmet needs and high rates of unnecessary complications and avoidable hospital readmissions. Nurses must use evidence-based approaches to prepare stroke survivors and their family caregivers for postdischarge self-management, rehabilitation, and recovery. The purpose of this article is to provide evidence on the important nursing roles in stroke care and transition management across the care continuum, discuss cross-setting issues in stroke care, and provide recommendations to leverage nursing's impact in optimizing outcomes for stroke survivors and their family unit across the continuum. To optimize nursing's influence in facilitating safe, effective, and efficient care transitions for stroke survivors and their family caregivers across the continuum we have the following recommendations (1) establish a system of coordinated and seamless comprehensive stroke care across the continuum and into the community; (2) implement a stroke nurse liaison role that provides consultant case management for the episode of care across all settings/services for improved consistency, communication and follow-up care; (3) implement a validated caregiver assessment tool to systematically assess gaps in caregiver preparedness and develop a tailored caregiver/family care plan that can be implemented to improve caregiver preparedness; (4) use evidence-based teaching and communication methods to optimize stroke survivor/caregiver learning; and (5) use technology to advance stroke nursing care. Nurses must leverage their substantial influence over the health care delivery system to achieve these improvements in stroke care delivery to improve the health and lives of stroke survivors and their families.

Skilled Nursing and Inpatient Rehabilitation Facility Use by Medicare Fee-for-Service Beneficiaries s Discharged Home following a Stroke: Findings from the COMPASS Trial

OBJECTIVES

To examine the effect of a comprehensive transitional care model on the utilization of skilled nursing facility (SNF) and inpatient rehabilitation facility (IRF) care in the 12 months after acute care discharge home following stroke; and to identify predictors of experiencing a SNF or IRF admission following discharge home after stroke.

DESIGN

Cluster randomized pragmatic trial Setting: 41 acute care hospitals in North Carolina.

PARTICIPANTS

2,262 Medicare fee-for-service beneficiaries with transient ischemic attack or stroke discharged home. The sample was 80.3% White and 52.1% female, with a mean (standard deviation [SD]) age of 74.9 (10.2) years and a mean (SD) NIH stroke scale score of 2.3 (3.7).

INTERVENTION

Comprehensive transitional care model (COMPASS-TC) which consisted of a 2-day follow-up phone call from the post-acute care coordinator (PAC) and 14-day in-person visit with the PAC and advanced practice provider.

MAIN OUTCOME MEASURES

Time to first SNF or IRF and SNF or IRF admission (yes/no) in the 12 months following discharge home. All analyses utilized multivariable mixed models including a hospital-specific random effect to account for the non-independence of measures within hospital. Intent to treat analyses using Cox proportional hazards regression assessed the effect of COMPASS-TC on time to SNF/IRF admission. Logistic regression was used to identify clinical and non-clinical predictors of SNF/IRF admission.

RESULTS

Only 34% of patients in the intervention arm received COMPASS-TC per protocol. COMPASS-TC was not associated with a reduced hazard of a SNF/ IRF admission in the 12 months post-discharge (HR=1.20 [0.95 - 1.52]) compared to usual care. This estimate was robust to additional covariate adjustment (HR=1.23 [0.93-1.64]). Both clinical and non-clinical factors (i.e., insurance, geography) were predictors of SNF/IRF use.

CONCLUSIONS

COMPASS-TC was not consistently incorporated into real-world clinical practice. The use of a comprehensive transitional care model for patients discharged home after stroke was not associated with SNF or IRF admissions in a 12-month follow-up period. Non-clinical factors predictive of SNF/IRF use suggest potential issues with access to this type of care.

Bite Force, Thickness, and Thermographic Patterns of Masticatory Muscles Post-Hemorrhagic Stroke

OBJECTIVE

Stroke is a neurological deficit of cerebrovascular origin, considered a 21st-century epidemic that causes functional changes in the human body. This study aimed to evaluate the stomatognathic system of patients after hemorrhagic stroke through the bite force, thickness, and skin temperature in the region of the masseter and temporalis muscles.

MATERIAL AND METHODS

Twenty-four subjects were divided into groups: post-hemorrhagic stroke; with right side of the affected body (n = 12) and without the neurological disorder (n = 12). Maximum molar bite force was verified using a digital dynamometer. Muscle thickness was measured using ultrasound images obtained at rest and during maximal voluntary contraction of the masseter and temporalis muscles. Thermographic camera was used to record the thermographic patterns of the masseter and temporalis muscles. Data were subjected to Student's t-test (P < .05).

RESULTS

The maximum molar bite force showed significant differences in the right (P = .04) and left (P = .03) sides, with a reduction in force in the post-hemorrhagic stroke group on the affected and unaffected sides. There was a significant difference (P < .05) in the thickness of the left temporal muscle at mandibular rest (P = .01) between groups. The post-hemorrhagic stroke group clinically presented greater muscle thickness in almost 100% of the muscles evaluated in both clinical conditions. There were no significant differences in skin temperature in the masseter and temporal muscles between the groups.

CONCLUSIONS

Our results suggest functional changes in the stomatognathic system of subjects after a hemorrhagic stroke, especially concerning molar bite force and masticatory muscle thickness in the temporal muscle (unaffected side).

Image Features of Magnetic Resonance Angiography under Deep Learning in Exploring the Effect of Comprehensive Rehabilitation Nursing on the Neurological Function Recovery of Patients with Acute Stroke

This study was to explore the effects of imaging characteristics of magnetic resonance angiography (MRA) based on deep learning on the comprehensive rehabilitation nursing on the neurological recovery of patients with acute stroke. In this study, 84 patients with acute stroke who were treated in hospital were selected as the research objects, and they were rolled into a control group (routine care) and an experimental group (comprehensive rehabilitation care). The dense dilated block-convolution neural network (DD-CNN) algorithm under deep learning for cerebrovascular was adopted to assess the effect of comprehensive rehabilitation care on the neurological recovery of patients with acute stroke. The results showed that the Berg scale scores, Fugl-Meyer scores, and Functional Independence Measure (FIM) scores of the experimental group of patients after 6 weeks and 12 weeks of comprehensive rehabilitation nursing were greatly different from those before treatment, showing statistical differences (P < 0.05). Compared with conventional magnetic resonance imaging (MRI) images, MRA images based on CNN algorithm, Dense Net algorithm, and DD-CNN algorithm can more clearly show the patient's cerebral artery occlusion. The average dice similarity coefficient (DSC) values of CNN algorithm, Dense Net algorithm, and DD-CNN algorithm were determined to be 84.3%, 95.7%, and 97.8%, respectively; the average sensitivity (Sen) values of the three algorithms were 76.1%, 95.4%, and 96.8%, respectively; and the average accuracy (Acc) values were 87.9%, 96.3%, and 97.9%, respectively. Thus, there were statistically obvious differences among the three algorithms in terms of average values of DSC, Sen, and Acc (P < 0.05). The MRA images processed by the DD-CNN algorithm showed that the degree of neurological recovery of the experimental group was observably greater than that of the control group, and the difference was statistically obvious (P < 0.05). In short, the image features of MRA based on the deep learning DD-CNN algorithm showed good application value in studying the effect of comprehensive rehabilitation nursing on the neurological recovery of patients with acute stroke, and it was worthy of promotion.

An Examination of History for Promoting Diversity in Neuroscience

Purpose of Review

A review of American history is presented to understand how public policy has contributed to a disproportionate burden of disease in members of underrepresented groups. A review of research conducted in the Stroke Belt provides an opportunity to examine more closely traditional and non-traditional risk factors in an effort to consider strategies for change.

Recent Findings

A diverse physician workforce has been offered as a way of improving care for our increasingly diverse populace. Given the expected increased prevalence of stroke in communities of color and the impact of stress from discrimination on health, proactive strategies to promote inclusion and equity to support diversity in perioperative neuroscience is warranted.

Summary

Public policy rooted in structural racism has left marginalized groups economically and educationally disadvantaged with less access to health care. Mistrust and fear from ongoing discrimination compels the neuroscience community to broaden their approach for developing a more reassuring and supportive educational environment for patients and trainees.

Epidemiology of atherosclerotic carotid artery disease

Atherosclerotic carotid artery disease is a significant cause of stroke in the United States and globally. Its prevalence increases with age and it is more prevalent in men and White and Native-American populations. However, the outcomes related to carotid disease are worse in women and Black patients. Research suggests the disparities exist due to a multitude of factors, including disease pathophysiology, access to care, provider bias, and socioeconomic status. The prevalence of carotid stenosis in the general population is low (3%), and routine screening for carotid stenosis is not recommended in adults. Randomized clinical trials have shown benefits of stroke risk reduction with surgery (carotid endarterectomy or stenting) for symptomatic patients. Management is controversial in asymptomatic patients, as modern medical management has results equivalent to those of surgery and ongoing randomized clinical trials will address this important question. Carotid surgery is not appropriate in asymptomatic patients with limited life expectancy. Future work should explore comprehensive care models for care of patients with carotid disease and assessment of patient-reported outcomes to measure quality of care.
