Relationship of Barthel Index and its Short Form with the Modified Rankin Scale in acute stroke patients

Relationship between maximum carotid plaque area and prognosis of patients with acute ischaemic stroke

OBJECTIVE

In this study, the relationship between maximum carotid plaque area and stroke prognosis was analysed by carotid ultrasonography, and the relevant risk factors affecting the prognosis of acute ischaemic stroke (AIS) were investigated to provide novel insights into stroke prevention and management.

METHODS

A total of 205 AIS patients with carotid plaques were included in this study. Based on the mRS score at discharge, patients with AIS were classified into the good prognosis group (mRS ≤ 2) and poor prognosis group (mRS ≥ 3). SPSS 25.0 was used to analyse the data. Univariate and multivariate analyses were performed on the two groups with good and poor prognosis. Comparison between good and poor prognosis in patients with AIS in different circulatory systems was performed using the Kruskal-Wallis test. Differences were considered statistically significant at P < 0.05.

RESULTS

Comparison of baseline data revealed differences in carotid plaque diameter, carotid intima-media thickness, maximum carotid plaque area, history of previous stroke and plaque echogenicity between the good and poor prognosis groups (P < 0.05). Results of multifactorial analyses of logistic binary regression indicated that history of previous stroke and maximum carotid plaque area were predictors of poor prognosis, with odds ratio of 2.515 (95%CI [1.327-4.764]) and 1.019 (95%CI [1.006-1.032]), respectively.

CONCLUSION

The maximum carotid plaque area and history of previous stroke are important predictors for assessing prognosis in patients with AIS.

Sensory training combined with motor training improves trunk proprioception in stroke patients: a single-blinded randomized controlled trial

OBJECTIVES

Inadequate trunk function is the underlying cause of many problems such as impaired balance and mobility. Although there have been trunk-based physiotherapy approaches in recent years, almost all of these approaches focus on motor problems. This study aims to investigate the effects of sensory training combined with trunk-centered Bobath exercises on trunk control and proprioception, balance, gait, and the activity of daily living (ADL).

MATERIALS AND METHODS

This study is a randomized controlled trial included with twenty-seven stroke patients. Participants were separated into two groups, Group 1; 'sensory training combined with trunk-centered Bobath exercises' and Group 2; 'trunk-centered Bobath exercises'. Trunk-centered Bobath exercises were used for motor training. Sensory training included transcutaneous electric nerve stimulation and a set of exercises that provide tactile and proprioceptive stimulation. Trunk Impairment Scale, Trunk Reposition Error, Berg Balance Scale, 2-minute walk test, and Barthel Index were used to assess trunk control, trunk proprioception, balance, gait, and ADL respectively.

RESULTS

Intra-group analysis results showed that trunk control, trunk proprioception, balance, gait, and ADL improved in both groups after treatment (p < 0.05). The changes in the Trunk Reposition Error values of the participants in Group 1 before and after treatment was found to be significantly higher than Group 2 (p < 0.05).

CONCLUSIONS

The findings indicated that the application of trunk-centered motor training is effective in improving trunk proprioception and trunk control, balance, gait, and ADL in stroke patients. Also, sensory training combined with trunk-centered motor training was found more effective in improving trunk proprioception than solely motor training.

Rehabilitation Assessment System for Stroke Patients Based on Fusion-Type Optoelectronic Plethysmography Device and Multi-Modality Fusion Model: Design and Validation

This study aimed to propose a portable and intelligent rehabilitation evaluation system for digital stroke-patient rehabilitation assessment. Specifically, the study designed and developed a fusion device capable of emitting red, green, and infrared lights simultaneously for photoplethysmography (PPG) acquisition. Leveraging the different penetration depths and tissue reflection characteristics of these light wavelengths, the device can provide richer and more comprehensive physiological information. Furthermore, a Multi-Channel Convolutional Neural Network-Long Short-Term Memory-Attention (MCNN-LSTM-Attention) evaluation model was developed. This model, constructed based on multiple convolutional channels, facilitates the feature extraction and fusion of collected multi-modality data. Additionally, it incorporated an attention mechanism module capable of dynamically adjusting the importance weights of input information, thereby enhancing the accuracy of rehabilitation assessment. To validate the effectiveness of the proposed system, sixteen volunteers were recruited for clinical data collection and validation, comprising eight stroke patients and eight healthy subjects. Experimental results demonstrated the system's promising performance metrics (accuracy: 0.9125, precision: 0.8980, recall: 0.8970, F1 score: 0.8949, and loss function: 0.1261). This rehabilitation evaluation system holds the potential for stroke diagnosis and identification, laying a solid foundation for wearable-based stroke risk assessment and stroke rehabilitation assistance.

Efficacy, safety, and cost-effectiveness analysis of Cerebrolysin in acute ischemic stroke: A rapid health technology assessment

This study conducts a rapid health technology assessment to systematically evaluate the effectiveness, safety, and cost-effectiveness of Cerebrolysin as an adjunctive therapy for acute ischemic stroke to provide evidence-based medicine for clinical decisions of Cerebrolysin. All systematic reviews/meta-analyses, pharmacoeconomic studies, and health technology assessment reports of Cerebrolysin for the treatment of acute ischemic stroke before August 17, 2023, were retrieved from PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang, Weipu, Sinomed database and the official website of health technology assessment. According to the inclusion and exclusion criteria, 2 researchers independently carried out screening, data extraction, and quality evaluation and descriptively analyzed the results of the included studies. A total of 14 pieces of literature were incorporated, comprising 8 systematic reviews/meta-analyses and 6 pharmacoeconomic studies. In terms of effectiveness, compared to control groups, the use of Cerebrolysin as a treatment for acute ischemic stroke demonstrates certain advantages, including enhancement in total efficacy rate, neurological function, upper limb motor dysfunction, and facilitation of the recovery of activities of daily living. Especially in patients with moderate to severe acute ischemic stroke, Cerebrolysin has demonstrated the ability to enhance neurological function recovery and ameliorate disabilities. Regarding safety, adverse reactions were mild or comparable to those in the control group. The primary findings of economic studies reveal that advocating for the use of Cerebrolysin offers certain cost-effectiveness advantages. Cerebrolysin contributes to improved clinical efficacy and evaluation indexes while demonstrating favorable safety and economic benefits.

Effect of comprehensive nursing on the quality of life and swallowing function in individuals diagnosed with ischemic stroke

BACKGROUND

Ischemic stroke (IS) is a widely recognized disease characterized by high prevalence, mortality, morbidity, disability, and recurrence rates. It ranks prominently in terms of mortality, constituting 60%-80% of stroke cases.

AIM

To explore the impact of comprehensive nursing care on the quality of life and swallowing function in individuals diagnosed with IS.

METHODS

This study comprised 172 patients with IS admitted to our hospital between February 2018 to March 2021. The participants were divided into two groups, namely the control group (n = 80) receiving routine care and the research group (n = 92) receiving comprehensive care. Various assessment scales, including the standard swallowing function assessment scale (SSA), National Institutes of Health Stroke scale (NIHSS), European stroke scale (ESS), self-rating anxiety scale (SAS), self-rating depression scale (SDS), Barthel index (BI), and the motor function assessment scale (MAS), were employed to evaluate the improvement in swallowing function, neurological deficits, clinical outcomes, anxiety, depression, daily living activities, and motor function before and after care. Furthermore, the study compared the occurrence of adverse reactions during the nursing period, life quality before and after the intervention, rehabilitation compliance, and nursing satisfaction between the two groups.

RESULTS

After the nursing intervention, the research group exhibited significantly improved SSA and NIHSS scores compared to the control group (P < 0.05). Moreover, both groups demonstrated significant reductions in SAS and SDS scores (P < 0.05), with the research group showing more obvious advantages (P < 0.05). Compared to the control group, the research group displayed significantly better ESS, BI, and MAS scores (P < 0.05), coupled with a lower incidence of adverse reactions (P < 0.05). Additionally, the research group demonstrated markedly higher levels of life quality, rehabilitation compliance, and nursing satisfaction compared to the control group (P < 0.05).

CONCLUSION

Comprehensive nursing effectively improved swallowing function, quality of life, and patient satisfaction, highlighting its clinical significance.

Non-adaptive cognitive emotion regulation mediates the relationship between disease uncertainty and acute stress disorder in patients with ischaemic stroke

Background

During epidemic outbreaks, hospitalized patients, especially those with cerebrovascular disease, were identified as a vulnerable group suffering from acute stress disorder (ASD) and consequent psychological distress. For stroke patients, not only will they suffer from physical illness, but the uncertainty of illness caused by sudden illness may also cause patients to experience different degrees of ASD. Relevant studies have shown that the impact of ASD on individuals may vary according to age, gender, disease characteristics, individual personality, treatment methods, income level, family support, cognitive psychology and other factors. However, non-adaptive cognitive emotion regulation plays a crucial role in influencing individual psychological states. At present, the risk factors of ASD after stroke and the mechanism between illness uncertainty and cognitive emotion regulation are not fully understood. Therefore, we focus on exploring the predictive effects of general demographic and disease-related characteristics, maladaptive cognitive emotion regulation, and illness uncertainty on ASD after stroke, and make hypotheses. When a disease acts on the body, the patient will have the corresponding cognition of the disease, and ASD will appear at the same time. Then the maladaptive cognitive emotion regulation as an important mediating variable can aggravate the level of acute stress disorder and be verified.

Methods

We used a cross-sectional design, which can be used to investigate the distribution of a disease or health condition and its related factors in a specific population at a specific time, so as to describe the distribution of the disease or health condition and its relationship with related factors. A total of 256 hospitalized patients with ischemic stroke were enrolled, including 145 males and 111 females, aged from 26 to 90 years, with a mean age of (64.71 ± 12.20) years. All patients completed and returned a self-report questionnaire that included demographic information, illness uncertainty, cognitive emotion regulation, and ASD. We then compared the differences in general demographic data, illness uncertainty, and maladaptive cognitive emotion regulation in acute stress disorders.

Results

The majority of hospitalized stroke patients (67.6%) developed ASD due to the COVID-19 pandemic and were therefore at risk for PTSD. More than one third (39.1%) of stroke survivors also suffered from severe psychological distress. More specifically, younger stroke patients are more likely to experience ASD than older patients. Although higher illness uncertainty scores indicate more severe ASD, adaptive cognitive emotion regulation was a protective factor.

Conclusion

Given that individuals with ASD are susceptible to PTSD, it is critical to follow up hospitalized patients with ischemic stroke for screening for PTSD and referral to appropriate psychological services. Maladaptive cognitive emotion regulation can increase the impact of uncertainty on the traumatic experience of stroke patients. Therefore, health care institutions should increase their efforts to provide psychosocial support services to hospitalized patients and make continuous efforts to screen for symptoms of trauma and psychological distress in hospitalized stroke patients.

Development and psychometric testing of the Self-Care of Stroke Inventory

PURPOSE

To develop and evaluate the psychometric properties of the Self-Care of Stroke Inventory (SCSI).

MATERIALS AND METHODS

A cross-sectional, instrument development and the psychometric testing study was conducted. A 23-item self-report Self-Care of Stroke Inventory with 3 separate scales was developed. This study involved three stages: (a) Initial items generation; (b) Content and face validation; (c) Psychometric properties evaluation. The SCSI was validated by content validity, construct validity, convergent validity, internal consistency, and test-retest reliability.

RESULTS

From the initial 80-item pool, 24 items of 3 scales in the SCSI were retained by the expert consultation and item analysis. The scale's content validity was 0.976, 0.966, and 0.973. The EFA showed the total variance explained by the 3 scales of the SCSI were 73.417%, 74.281%, and 80.207%, respectively. The models of the 3 scales identified by EFA were all confirmed by the CFA. The SCSI scale shows evidence of good convergent validity. Cronbach's αs were 0.830, 0.930, and 0.831. Test-retest reliability of the SCSI was excellent, with an intraclass correlation coefficient of 0.945, 0.907, and 0.837.

CONCLUSIONS

The final 23-item SCSI presents good psychometric properties and can be used to explore the self-care of stroke in community settings.IMPLICATIONS FOR REHABILITATIONThis study developed and validated the Self-Care of Stroke Inventory (SCSI).The SCSI contains the following 3 scales: the Self-care Maintenance of Stroke scale, the Self-care Monitoring of Stroke scale, and the Self-care Management of Stroke scaleThe 23-item SCSI demonstrated strong psychometric properties.The SCSI may be used to develop future programmes to promote self-care for stroke survivors and improve their rehabilitation outcomes.

Inverted U-shaped relationship between Barthel Index Score and falls in Chinese non-bedridden patients: a cross-sectional study

BACKGROUND

Performing activities of daily living comprise an important risk factor for falls among non-bedridden stroke inpatients in rehabilitation departments.

OBJECTIVES

To explore the correlation between Barthel Index score and the occurrence of falls in non-bedridden stroke rehabilitation inpatients.

METHODS

In this cross-sectional study, information of patients grouped as non-bedridden patients by the Longshi Scale was collected.

RESULTS

A total of 3097 patients were included in this study, with a fall incidence of 10.43%. After adjusting covariates, the total score of Barthel Index and falls in non-bedridden inpatients after stroke presented an inverted U-shaped curve relationship, in which inflection point was 60. The effect sizes on the left and right sides of infection point were 1.02 (95%CI 1.00-1.04) and 0.97 (95%CI 0.96-0.99), respectively.

CONCLUSIONS

Non-bedridden stroke patients with moderate activities of daily living (ADL) capacity may be at particularly increased risk of falls in rehabilitation departments.

Assessment of functional fitness impacted by hospital rehabilitation in post-stroke patients who additionally contracted COVID-19

Background

The aim of the study was to assess the effects of rehabilitation in post-stroke patients, or post-stroke patients with simultaneous COVID-19 infection, in relation to: improved locomotion efficiency, improved balance, reduced risk of falling as well as the patients' more effective performance in everyday activities.

Methods

The study involved 60 patients in the early period (2-3 months) after a stroke. Group I consisted of 18 patients (30.0%) who, in addition to a stroke, also contracted COVID-19. Group II consisted of 42 patients (70%) post-stroke, with no SARS-CoV2 infection. The effects were assessed on the basis of: Tinetti test, Timed Up & Go test and Barthel scale.

Results

Both groups achieved a statistically significant improvement in their Barthel score after therapy (p < 0.001). The Tinetti test, assessing gait and balance, showed that participants in Group I improved their score by an average of 4.22 points. ±4.35, and in Group II, on average, by 3.48 points ± 3.45 points. In the Timed Up & Go test over a distance of 3 m, significant improvement was achieved in both groups, as well but the effect was higher in Group I (p < 0.001).

Conclusions

Hospital rehabilitation in the early period after stroke improved locomotion efficiency and balance, and reduced the risk of falls in post-stroke patients, both with and without COVID-19 infection.

Influence of hyperbaric oxygen therapy-specialized care on limb motor function and mental state of cerebral infarction patients with hemiplegia

BACKGROUND

Currently, cerebral infarction (CI) is mainly treated by emergency craniotomy or conservative treatment. However, some studies have questioned the functional recovery of patients after hyperbaric oxygen therapy (HBOT)-specialized care.

OBJECTIVE

This paper mainly explores the influence of HBOT-specialized care on limb motor function (LMF) and mental state of CI patients with hemiplegia.

METHODS

The medical records of 113 CI patients with hemiplegia treated in our hospital from March 2020 to March 2022 were collected. Of these, 53 received routine care nursing (conventional group) and 60 cases were given HBOT-specialized care (research group). Patient general data, scores of Fugl-Meyer Assessment (FMA), National Institutes of Health Stroke Scale (NIHSS), Self-rating Anxiety/Depression Scale (SAS/SDS) and Barthel Index (BI), and nursing efficiency were comparatively analyzed.

RESULTS

The two groups showed comparability in general data. FMA and BI scores were increased in the research group after rehabilitation treatment, higher than the baseline and those of the conventional group, while NIHSS, SAS, and SDS scores were reduced, lower compared with baseline and those of the conventional group. In addition, significantly higher nursing efficiency was determined in the research group.

CONCLUSION

HBOT-specialized care has beneficial effects on LMF, mental state, negative emotions and self-care ability of CI patients with hemiplegia and can enhance nursing efficacy, which deserves clinical popularization.

Application effect of diversified health-promoting models on rehabilitation exercises for cervical spondylotic myelopathy

BACKGROUND

With improving living standards, the incidence of cervical spondylotic myelopathy (CSM) has become increasingly high.

OBJECTIVE

The study aims to explore the effect of diversified health-promoting models on rehabilitation exercises in patients with CSM after an operation.

METHOD

This was a randomized controlled trial, wherein 107 patients with CSM treated by neurosurgery were selected as the subjects. Of those, 52 patients in the control group adopted the conventional health-promoting model, while the remaining 55 patients in the intervention group adopted diversified health-promoting models. The effect of rehabilitation exercises in the two groups was evaluated according to the self-efficacy rehabilitation outcome scale, grip strength measurement of the affected limb, and Barthel index.

RESULTS

At Day 3 post-operation and before discharge, the self-efficacy management of rehabilitation exercises in the intervention group was better than that of the control group (P< 0.05). The grip strength measurement of the affected limb, Japanese Orthopedic Association score of the cervical vertebra, and Barthel index of the two groups at Day 3 post-operation were lower than before the intervention and were not statistically significant (P> 0.05). However, these three items before discharge were improved when compared with those of before intervention and were statistically significant (P< 0.05).

CONCLUSION

Postoperative rehabilitation exercises guided by the diversified health-promoting models for patients with CSM can improve the patients' self-efficacy management ability in rehabilitation exercises, help improve grip strength, and promote the recovery of cervical vertebra function, thereby improving the patients' quality of life.

Prognostic Neuroimaging Biomarkers in Acute Vascular Brain Injury and Traumatic Brain Injury

Prognostic imaging biomarkers after acute brain injury inform treatment decisions, track the progression of intracranial injury, and can be used in shared decision-making processes with families. Herein, key established biomarkers and prognostic scoring systems are surveyed in the literature, and their applications in clinical practice and clinical trials are discussed. Biomarkers in acute ischemic stroke include computed tomography (CT) hypodensity scoring, diffusion-weighted lesion volume, and core infarct size on perfusion imaging. Intracerebral hemorrhage biomarkers include hemorrhage volume, expansion, and location. Aneurysmal subarachnoid biomarkers include hemorrhage grading, presence of diffusion-restricting lesions, and acute hydrocephalus. Traumatic brain injury CT scoring systems, contusion expansion, and diffuse axonal injury grading are reviewed. Emerging biomarkers including white matter disease scoring, diffusion tensor imaging, and the automated calculation of scoring systems and volumetrics are discussed.

Primary Intracranial Hemorrhage: Characteristics, Distribution, Risk Factors, and Outcomes-A Comparative Study between Jewish and Arab Ethnic Groups in Northern Israel

Background and purpose: This study aimed to investigate the differences in intracerebral hemorrhage (ICH) between Jews and Arabs residing in northern Israel, focusing on risk factors, hemorrhage volume, and functional outcome. Methods: A retrospective analysis was conducted utilizing a population-based registry to investigate intracerebral hemorrhage (ICH) characteristics, risk factors, and outcomes. The registry consisted of inpatients diagnosed with hemorrhagic stroke. Due to the wide variation in data on ICH characteristics and the limited availability of population-based data on predictors of ICH survival and functional outcomes, we collected retrospective data on all adult patients admitted to the Galilee Medical Center with a diagnosis of ICH. Data were obtained from the registry covering the period from 2013 to 2019. Ethnic differences and risk factors associated with intracranial hemorrhage (ICH) were examined within a diverse population of 241 patients, comprising 52.70% Jews (n = 127) and 47.30% Arabs (n = 114). Results: The results of this study revealed significant differences in age, obesity rates, and intracerebral hemorrhage (ICH) location between the two ethnic groups. Hypertension emerged as the most prevalent condition among ICH patients in both ethnic groups (76.70%), followed primarily by anticoagulant use (63.60%), dyslipidemia (60.70%), diabetes (44.60%), obesity (30.60%), smoking (24.60%), and a history of cardiovascular disease (21.80%). Furthermore, 20.90% of the patients had a history of previous cerebrovascular accidents (CVA). Arab patients with ICH were generally younger (62.90 ± 16.00 years) and exhibited higher rates of obesity (38.70%) compared to Jewish patients with ICH (70.17 ± 15.24 years, 23% obesity; p = 0.001, p = 0.013, respectively). Hemorrhage volume was identified as a crucial determinant of patient outcomes, with larger volumes associated with poorer Modified Rankin Scale (mRS) scores at discharge and higher mortality rates. Interestingly, patients without hypertension had higher hemorrhage volumes compared to those with hypertension. The extent of hemorrhage into the ventricles did not significantly correlate with mRS at discharge in our dataset. Conclusions: This study highlights significant differences in the characteristics and outcomes of intracranial hemorrhage (ICH) between Jews and Arabs in northern Israel. The findings reveal variations in age, obesity rates, and ICH location between the two groups. While hypertension was the most prevalent risk factor for both populations, other risk factors differed. Notably, hemorrhage volume emerged as a crucial prognostic factor, aligning with previously published data. These findings underscore the necessity for tailored approaches that consider ethnic-specific factors in the risk assessment, prevention, and management of ICH. Further research is warranted to elucidate the underlying mechanisms and develop interventions aimed at improving outcomes and enhancing healthcare practices in ICH management.

Demographic and clinical factors associated with recovery of poststroke dysphagia: A meta-analysis

BACKGROUND

Poststroke dysphagia (PSD) recovery depends on various factors. We aimed to provide evidence concerning predictive variables for the recovery of PSD.

METHODS

PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP database of Chinese periodicals, Chinese biomedical literature service system (SinoMed), and Cochrane Library databases were systematically searched up to September 21, 2022. According to the inclusion criteria, the literature searched in the database was screened. The methodological quality of included studies was assessed using the Newcastle-Ottawa Scale (NOS). Meta-analysis was performed to identify the factors prognostic for PSD.

RESULTS

Twenty-eight studies were eligible, and pooled analyses were allowed for 12 potential prognostic factors. We identified older age, higher National Institutes of Health Stroke Scale (NIHSS) score, lower activities of daily living (ADL) score, lower body mass index (BMI), severe dysphagia on admission, aspiration, brainstem stroke, severe cognitive impairment, and bilateral hemispheric stroke were negative factors for the recovery of PSD, while early intervention and Modified Rankin Scale (mRS) = 0 before onset were protective factors for the recovery of PSD. There was no significant association between stroke type and prognosis of PSD.

CONCLUSION

Prognostic factors of PSD summarized in this meta-analysis could be useful for developing reasonable treatment plan to better promote recovery of swallowing function after stroke.

Impact of extended nursing model after multi-disciplinary treatment on young patient with post-stroke

BACKGROUND

Stroke has become one of the most serious life-threatening diseases due to its high morbidity, disability, recurrence and mortality rates.

AIM

To explore the intervention effect of multi-disciplinary treatment (MDT) extended nursing model on negative emotions and quality of life of young patients with post-stroke.

METHODS

A total of 60 young stroke patients who were hospitalized in the neurology department of our hospital from January 2020 to December 2021 were selected and randomly divided into a control group and an experimental group, with 30 patients in each group. The control group used the conventional care model and the experimental group used the MDT extended nursing model. After the in-hospital and 3-mo post-discharge interventions, the differences in negative emotions and quality of life scores between the two groups were evaluated and analyzed at the time of admission, at the time of discharge and after discharge, respectively.

RESULTS

There are no statistically significant differences in the negative emotions scores between the two groups at admission, while there are statistically significant differences in the negative emotions scores within each group at admission and discharge, at discharge and post-discharge, and at discharge and post-discharge. In addition, the negative emotions scores were all statistically significant at discharge and after discharge when compared between the two groups. There was no statistically significant difference in quality of life scores at the time of admission between the two groups, and the difference between quality of life scores at the time of admission and discharge, at the time of discharge and post-discharge, and at the time of admission and post-discharge for each group of patients was statistically significant.

CONCLUSION

The MDT extended nursing mode can improve the negative emotion of patients and improve their quality of life. Therefore, it can be applied in future clinical practice and is worthy of promotion.

The relationship between the baseline geriatric nutritional risk index (GNRI) and neurological function at the convalescence stage in patients with stroke: a cross-sectional study

BACKGROUND

Malnutrition is a common complication after stroke and may worsen neurological outcomes for patients. There are still no uniform tools for screening nutritional status for the patients with stroke. We aimed to explore the relationship between the baseline geriatric nutritional risk index (GNRI) and neurological function at the convalescence stage for patients with stroke and assessed the predictive value of the GNRI for adverse neurological outcomes.

METHODS

A total of 311 patients with stroke were enrolled retrospectively. Basic information and laboratory results on admission since onset of stroke were collected. The GNRI on admission was calculated and neurological outcomes evaluated by the Barthel index at 1 month after the onset of stroke. Statistical analyses, including correlation coefficient tests, multivariate regression analyses, and receiver operating characteristic (ROC) analyses, were applied in this study.

RESULTS

Compared with the good outcome group, the poor outcome group showed a significantly lower GNRI on admission (P < 0.05). GNRI was associated with Barthel index (r = 0.702, P < 0.01). The GNRI was independently correlated with the Barthel index (Standardization β = 0.721, P < 0.01) and poor outcome 0.885 (95% CIs, 0.855-0.917, P < 0.01) after adjusting for covariates. Compared with no nutritional risk grades (Q4), the OR of GNRI to poor neurological outcome increased across increasing nutritional risk grades of GNRI (OR = 2.803, 95% CIs = 1.330-5.909 in Q3, 7.992, 95% CIs = 3.294-19.387 in Q2 and 14.011, 95% CIs = 3.972-49.426 in Q1, respectively, P for trend < 0.001). The area under ROC curves (AUC) of the GNRI was 0.804, which was larger than that of the NIHSS, BMI, or Albumin (P < 0.01), with an optimal cut-off value of 97.69, sensitivity of 69.51% and specificity of 77.27%. Combined GNRI with NIHSS gained the largest AUC among all the variables (all P < 0.05), with an AUC of 0.855, sensitivity of 84.75 and specificity of 72.73%.

CONCLUSIONS

For patients with stroke, higher nutritional risk grades at baseline indicated worse neurological function at the convalescence stage. Compared with NIHSS, BMI, and Albumin, GNRI was a competitive indicator for the risk of poor neurological outcome. The predictive property of GNRI for adverse neurological outcomes might be more powerful when combined with NIHSS.

Influence of humanized nursing on patients with intracranial aneurysm subarachnoid hemorrhage undergoing interventional embolization

Objective

To investigate the effect of nursing intervention on patients with intracranial aneurysm subarachnoid hemorrhage who underwent interventional embolization.

Methods

According to the random number table method, 80 patients with subarachnoid hemorrhage caused by intracranial aneurysm who received interventional embolization in our hospital from September 2018 to May 2021 were randomly divided into a control group of 40 cases and an observation group of 40 cases. 40 cases, the two groups were implemented routine nursing and humanized nursing.

Results

Compared with before nursing, the anxiety score, depression score, compliance rate, complication rate and PSQI score of the observation group were significantly lower than those of the control group after nursing (P < 0.05); Karnofsky Performance Status Scale score, Activity of daily living scale of the observation group and quality of life scores were significantly higher than those in the control group (P < 0.05).

Conclusion

Humanized nursing can effectively improve the psychological state of patients with subarachnoid hemorrhage caused by intracranial aneurysm during the perioperative period of interventional embolization, enhance their compliance with treatment, reduce complications, and make patients more satisfied with nursing services.

Associations between cardiac structure and function and depressive disorder: A centenarian study in China

Background

Depressive disorder is a common comorbidity in patients with cardiovascular diseases and is associated with increased hospitalization and death rates. The relationships between cardiac structure and function and depressive disorder remains unclear in the older adults, especially in centenarians. Therefore, this study aimed to explore the possible associations between cardiac structure and function and depressive disorder among centenarians.

Methods

In the China Hainan Centenarian Cohort Study, the 15-item Geriatric Depression Scale scores and echocardiography were used to evaluate depressive disorder and cardiac structure and function, respectively. All information, including epidemiological questionnaires, physical examinations, and blood tests, was obtained following standardized procedures.

Results

A total of 682 centenarians were enrolled in the study (mean age: 102.35 ± 2.72 years). The prevalence of depressive disorder in centenarians is 26.2% (179 older adults), of whom 81.2% (554 older adults) are women. Centenarians with depressive disorder have significantly higher left ventricular ejection fraction (60.02 ± 3.10) and interventricular septum thickness (9.79 ± 1.54). Stepwise multiple linear regression analysis detected positive associations of left ventricular ejection fraction (Bets: 0.093) and interventricular septum thickness (Bets: 0.440) with Geriatric Depression Scale scores. Both left ventricular ejection fraction (odds ratio: 1.081) and interventricular septum thickness (odds ratio: 1.274) were independently associated with depressive disorder in multiple logistic regression analysis (P < 0.05, all).

Conclusions

The prevalence of depressive disorder remains very high, and associations were found between left ventricular ejection fraction, interventricular septum thickness, and depressive disorder in Chinese centenarians. Future studies should focus on their temporal relationships to improve cardiac structure and function, prevent depressive disorder, and achieve healthy aging by coordinating their relationships.

Superficial temporal artery-middle cerebral artery bypass in combination with encephalo-myo-synangiosis in Chinese adult patients with moyamoya disease

Objective

To evaluate the feasibility and safety of superficial temporal artery (STA)-middle cerebral artery (MCA) anastomosis in combination with encephalo-myo-synangiosis (EMS) in Chinese adult patients with moyamoya disease (MMD).

Methods

A total of 65 patients with MMD who underwent combined STA-MCA bypass + EMS surgical revascularisation were included in this study. Each patient had a follow-up visit 6 months after discharge. Early bypass function was evaluated via computed tomography angiography and digital subtraction angiography, which were performed preoperatively and at 6 months after surgery. The perfusion parameters of cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT) and time to peak (TTP) were obtained and analysed. The clinical status of each patient was evaluated using a modified Rankin scale (mRS) preoperatively and at 1 week and 6 months after surgery.

Results

Among the 65 enrolled patients, postoperative complications were observed in 5 (7.69%) patients, with 2 cases of dysphasia, 2 cases of new cerebral infarction and 1 case of seizure. Six months after surgery, 66 out of 68 hemispheres were found to have a functioning extra-intracranial bypass, and the patency rate was 97.06%. In terms of CBF perfusion, both the CBF and CBV increased significantly, while the MTT and TTP decreased after surgery. The mRS scores measured 1 week and 6 months after surgery were much lower than those measured preoperatively.

Conclusion

A direct STA-MCA bypass procedure in combination with indirect EMS bypass is feasible and safe for Chinese adult patients with MMD.

Study on the Applicability of Digital Twins for Home Remote Motor Rehabilitation

The COVID-19 pandemic created the need for telerehabilitation development, while Industry 4.0 brought the key technology. As motor therapy often requires the physical support of a patient's motion, combining robot-aided workouts with remote control is a promising solution. This may be realised with the use of the device's digital twin, so as to give it an immersive operation. This paper presents an extensive overview of this technology's applications within the fields of industry and health. It is followed by the in-depth analysis of needs in rehabilitation based on questionnaire research and bibliography review. As a result of these sections, the original concept of controlling a rehabilitation exoskeleton via its digital twin in the virtual reality is presented. The idea is assessed in terms of benefits and significant challenges regarding its application in real life. The presented aspects prove that it may be potentially used for manual remote kinesiotherapy, combined with the safety systems predicting potentially harmful situations. The concept is universally applicable to rehabilitation robots.

Efficacy and Cost over 12 Hospitalization Weeks of Postacute Care for Stroke

Few studies have investigated changes in functional outcomes and economic burden in patients in the postacute care cerebrovascular disease (PAC-CVD) program. We, for the first time, retrospectively investigated changes in functional performance and the national health insurance (NHI) cost over 12 PAC-CVD hospitalization weeks and evaluated the therapeutic effects of the PAC-CVD program on the NHI cost. Specifically, the functional outcomes and NHI cost of 263 stroke patients in the PAC-CVD program were analyzed. The repeated measures t test was used to compare functional performance over 0-3 weeks, and a one-way repeated measures multivariate analysis of variance was used to compare functional performance and NHI costs during weeks 0-6 and 0-9. The Wilcoxon signed-rank test was used to compare functional performance over weeks 9-12. Hierarchical multiple regression was used to estimate the effects of functional performance on NHI costs during weeks 3, 6, and 9. Over weeks 0-12, all functional performance measures demonstrated significant improvements. Changes in NHI costs varied depending on whether hospitalization was extended. At any time point, functional performance did not have a significant impact on NHI cost. Therefore, the PAC-CVD program may aid patients with stroke in sustainably regaining functional performance and effectively controlling economic burden.

Effectiveness of cerebellar vermis intermittent theta-burst stimulation in improving trunk control and balance function for patients with subacute stroke: a randomised controlled trial protocol

INTRODUCTION

Balance impairments frequently occur after stroke. Achieving effective core trunk stability is the key to improving balance ability. However, there is still a lack of advanced well-defined rehabilitation protocols for balance improvement in patients with stroke. Intermittent theta-burst stimulation (iTBS) is a non-invasive brain activity modulation strategy that can produce long-term potentiation. The cerebellar vermis is a fundamental structure involved in balance and motor control. However, no study has demonstrated the therapeutic effect and potential mechanism of cerebellar vermis iTBS on balance after stroke.

METHODS AND ANALYSIS

This study will be a prospective single-centre double-blind randomised controlled clinical trial with a 3-week intervention and 3-week follow-up. Eligible participants will be randomly allocated to the experimental group or the control group in a 1:1 ratio. After routine conventional physical therapy, patients in the experimental group will receive cerebellar vermis iTBS, whereas patients in the control group will receive sham stimulation. The overall intervention period will be 5 days a week for 3 consecutive weeks. The outcomes will be measured at baseline (T0), 3 weeks postintervention (T1) and at the 3-week follow-up (T2). The primary outcomes are Berg Balance Scale and Trunk Impairment Scale scores. The secondary outcomes are balance test scores via the Balance Master system, muscle activation of the trunk and lower limbs via the surface electromyography recordings, cerebral cortex oxygen concentrations measured via the resting-state functional near-infrared spectroscopy, Fugl-Meyer Assessment of Lower Extremity and Barthel index scores.

ETHICS AND DISSEMINATION

This study was approved by the West China Hospital Clinical Trials and Biomedical Ethics Committee of Sichuan University. All participants will sign the informed consent form voluntarily. The results of this study will be published in peer-reviewed journals and disseminated at academic conferences.

Diaphragmatic ultrasound can help evaluate pulmonary dysfunction in patients with stroke

Objective

Pulmonary dysfunction after stroke is increasingly gaining attention from clinical and rehabilitation specialists. However, owing to cognitive and motor dysfunction in patients with stroke, determining the pulmonary function of these patients remains challenging. The present study aimed to devise a simple method for an early evaluation of pulmonary dysfunction in patients with stroke.

Methods

Overall, 41 patients with stroke in the recovery period (stroke group) and 22 matched healthy controls (control group) were included in the study. We first collected data regarding baseline characteristics for all participants. Furthermore, the participants with stroke were examined using additional scales, such as the National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer assessment scale (FMA), and modified Barthel Index (MBI). Subsequently, we examined the participants with simple pulmonary function detection and diaphragm ultrasound (B-mode). Ultrasound indices calculated were as follows: the thickness of the diaphragm under the position of functional residual capacity (TdiFRC), the thickness of the diaphragm under the position of forced vital capacity (TdiFVC), thickness fraction, and diaphragmatic mobility. Finally, we compared and analyzed all data to identify group differences, the correlation between pulmonary function and diaphragmatic ultrasound indices, and the correlation between pulmonary function and assessment scale scores in patients with stroke, respectively.

Results

Compared with the control group, patients in the stroke group exhibited lower values for indices of pulmonary and diaphragmatic function (p < 0.001), except for TdiFRC (p > 0.05). The majority of the patients with stroke had restrictive ventilatory dysfunction, as indicated by a significantly higher incidence ratio (36 in 41 patients) than that in the control group (0 in 22 patients) (p < 0.001). Moreover, significant correlations were found between pulmonary function and diaphragmatic ultrasound indices (p < 0.05), with the strongest correlation between TdiFVC and pulmonary indices. In the stroke group, pulmonary function indices were negatively correlated with the NIHSS scores (p < 0.001) and positively correlated with the FMA scores (p < 0.001). No (p > 0.05) or weak (p < 0.05) correlation was found between pulmonary function indices and the MBI scores.

Conclusion

We found that patients with stroke had pulmonary dysfunction even in the recovery period. Diaphragmatic ultrasound can be used as a simple and effective tool for detecting pulmonary dysfunction in patients with stroke, with TdiFVC being the most effective index.

Reliability of pictorial Longshi Scale for informal caregivers to evaluate the functional independence and disability

AIM

The pictorial Longshi Scale was designed to assess patients' functional ability in the Chinese context, which is gradually used by some informal caregivers. However, its reliability compared with healthcare professionals has not been examined.

DESIGN

A multi-centre cross-sectional study conducted in 24 Chinese hospitals.

METHODS

We recruited patients undergoing rehabilitation treatment and informal caregiver dyads. Informal caregivers and healthcare professionals evaluated patients' functional ability using the Longshi Scale according to three levels (bedridden, domestic and community). The Kappa coefficient and McNemar-Bowker test were used to examine the consistency and accuracy between the two parallel assessments.

RESULTS

This study involved 947 patients (mean age: 46.07 ± 11.72 years) and informal caregiver dyads (64.86 ± 12.94 years). Most patients were males (66.3%), while most caregivers were females (60.7%). Over 70% of patients and caregiver dyads had a secondary-school education and lower. Around 90% of caregivers were relatives (spouse, 42.8%; offspring, 20.7%; siblings: 13.3%; parent, 12.0%) of patients. The agreement in sub-levels of the Longshi Scale between caregivers and healthcare professionals ranges from 73%-89%, and the corresponding Kappa coefficients range from 0.504-0.786. Caregivers were more likely to assign fewer patients to the bedridden group and more to the domestic group than healthcare professionals. The subgroup analysis by education level indicated that the difference in assigning patients into three degrees of functional disability was only significant in those with primary-school education, while non-significant in those with secondary-school education and higher.

CONCLUSION

The evaluation outcomes of functional ability using the Longshi Scale are similar between informal caregivers and healthcare professionals. However, informal caregivers' education level is a dominant factor in affecting the assessment accuracy compared with healthcare professionals. Informal caregivers with a secondary-school education and higher are supported to evaluate patients' functional ability independently.

Application of an adjustable medical foot support pillow to prevent foot drop in patients with stroke

BACKGROUND: Foot drop is one of the most common complications after stroke. OBJECTIVE: This study investigates the role of an adjustable medical foot support pillow in preventing foot drop and improving the lower limb function of patients after stroke. METHODS: A total of 88 patients with strokes admitted to our hospital from September 2019 to September 2020 were selected and categorised into the control (n= 44) and intervention groups (n= 44) using a random number table. The control group received routine rehabilitation nursing, while the intervention group adopted a self-made adjustable medical foot support pillow based on routine rehabilitation nursing. After four weeks, the simplified Fugl Meyer Assessment (FMA) and the modified activities of daily living (ADL) scales were used to measure the ankle range of motion of the lower limbs. The lower limb motor function, ADL, and ankle mobility before and after treatment, as well as the incidence of foot ptosis, were compared between the two groups. RESULTS: After the procedure, the intervention group was superior to the control group in the FMA score of the lower extremities, ADL score, and ankle joint mobility in the lower limbs, indicating statistically significant differences (P< 0.05). The incidence rate of foot drop was lower in the intervention group than in the control group, and the difference was statistically significant (P< 0.05). CONCLUSION: The adjustable medical foot support pillow can prevent foot drop in patients after stroke, improve lower limb function, provide a favourable basis for walking training, and improve the ADL of patients.

Clinical Criteria for Persistent Inflammation, Immunosuppression, and Catabolism Syndrome: An Exploratory Analysis of Optimal Cut-Off Values for Biomarkers

Background: While clinical criteria have been proposed for persistent inflammation, immunosuppression, and catabolism syndrome (PICS) using C-reactive protein (CRP), albumin, and lymphocyte count, there is no substantial basis for their optimal cut-off values. We herein aimed to develop and externally validate clinical criteria for PICS by investigating the optimal cut-off values for these biomarkers using machine-learning approaches and confirmed it with external validation. Methods: To develop criteria, we included ICU patients treated at a tertiary care hospital in Japan between 2018 and 2021 (derivation cohort). We introduced CRP, albumin and lymphocyte counts at around day 14 into six machine-learning models to predict PICS, defined as the compound outcome of the Barthel index (BI) < 70 at hospital discharge and in-hospital death. We incorporated the results of these models to assess the optimal cut-off values for biomarkers. We then developed and externally validated criteria for PICS using a nationwide claims database in Japan (validation cohort). Results: In the derivation cohort, 291 out of 441 patients had BI < 70 or in-hospital death. Based on machine-learning models, the optimal cut-off values for biomarkers to predict them were a CRP of 2.0 mg/dL, albumin of 3.0 g/dL, and a lymphocyte count of 800/μL, with an AUROC of 0.67. In the external validation cohort, 4492 out of 15,302 patients had BI < 70 or in-hospital death. The AUROC of the criteria was 0.71, with sensitivity of 0.71 and specificity of 0.68 to predict PICS. Conclusions: We herein provide a fundamental basis for PICS clinical criteria with CRP >2.0 mg/dL, albumin <3.0 g/dL, and a lymphocyte count <800/μL on day 14. The criteria developed will identify patients with PICS whose long-term mortality and activity of daily living may be poor.

Early Rehabilitation Exercise after Stroke Improves Neurological Recovery through Enhancing Angiogenesis in Patients and Cerebral Ischemia Rat Model

Among cerebrovascular diseases, ischemic stroke is a leading cause of mortality and disability. Thrombolytic therapy with tissue plasminogen activator is the first choice for clinical treatment, but its use is limited due to the high requirements of patient characteristics. Therefore, the choice of neurological rehabilitation strategies after stroke is an important prevention and treatment strategy to promote the recovery of neurological function in patients. This study shows that rehabilitation exercise 24 h after stroke can significantly improve the neurological function (6.47 ± 1.589 vs. 3.21 ± 1.069 and 0.76 ± 0.852), exercise ability (15.68 ± 5.95 vs. 162.32 ± 9.286 and 91.18 ± 7.377), daily living ability (23.37 ± 5.196 vs. 66.95 ± 4.707 and 6.55 ± 2.873), and quality of life (114.39 ± 7.772 vs. 168.61 ± 6.323 and 215.95 ± 10.977) of patients after 1 month and 3 months, and its ability to promote rehabilitation is better than that of rehabilitation exercise administered to patients 72 h after stroke (p < 0.001). Animal experiments show that treadmill exercise 24 h after middle cerebral artery occlusion and reperfusion can inhibit neuronal apoptosis, reduce the volume of cerebral infarction on the third (15.04 ± 1.07% vs. 30.67 ± 3.06%) and fifth (8.33 ± 1.53% vs. 30.67 ± 3.06%) days, and promote the recovery of neurological function on the third (7.22 ± 1.478 vs. 8.28 ± 1.018) and fifth (4.44 ± 0.784 vs. 6.00 ± 0.767) days. Mechanistic studies have shown that treadmill exercise increases the density of microvessels, regulates angiogenesis, and promotes the recovery of nerve function by upregulating the expression of vascular endothelial growth factor and laminin. This study shows that rehabilitation exercise 24 h after stroke is conducive to promoting the recovery of patients’ neurological function, and provides a scientific reference for the clinical rehabilitation of stroke patients.

Effective Analysis of Multichannel Functional Electrical Stimulation plus Early Rehabilitation Training for Hemiplegic Patients after Stroke

Purpose

The research paper aims to investigate the value of multichannel functional electrical stimulation (FES) plus early rehabilitation training for hemiplegic patients after stroke attacks and assesses the impact of the combined therapy on walking capacity and daily life activities of patients.

Methods

Totally, 100 hemiplegic patients after stroke treated in No. 215 Hospital of Shaanxi Nuclear Industry from March 2019 to July 2020 were recruited and randomized into the control group and study group, with 50 cases in each group. The control group received early rehabilitation training, and the study group received multiple channel FES plus early rehabilitation. The rehabilitation effective rate, the Fugl-Meyer Assessment (FMA), the Berg Balance Scale (BBS), National Institutes of Health Stroke Scale (NIHSS), Barthel index (BI), the Quality of Life index (QLI), Mental Status Scale in Nonpsychiatric Settings (MSSNS), Self-rating Anxiety Scale (SAS), Self-rating depression scale (SDS), and the incidence of adverse response were evaluated.

Results

The study group patients had higher scores in FMA, BBS, BI, and QLI than the control group. Multiple channel FES plus early rehabilitation adopted in the study group resulted in a higher rehabilitation efficacy and a longer walking duration at 1, 2, and 4 weeks after the treatment. NIHSS score, MSSNS score, SAS score, SDS score, and incidence rate of adverse response in the study group were significantly lower compared to those of the control group.

Conclusions

Multichannel FES plus early rehabilitation training effectively enhances the rehabilitation of patients after stroke attacks.

Effectiveness of Multidisciplinary Nursing Based on Fever, Blood Sugar, and Swallowing Function Management in Patients with Acute Stroke

Purpose

The aim of this study was to assess the effectiveness of multidisciplinary nursing based on fever, blood sugar, and swallowing function management in patients with acute stroke (AS).

Methods

A total of 200 AS patients who were treated in our hospital from January 2016 to January 2020 were recruited and randomized at a ratio of 1 : 1 into a control group and a study group. The control group received standardized early rehabilitation nursing, and the study group received multidisciplinary nursing based on fever, blood sugar, and swallowing function management plus standardized early rehabilitation nursing. The patients were also assigned different blood glucose levels upon admission to a high blood glucose group or a normal blood glucose group. The clinical endpoint is clinical efficacy.

Results

Multidisciplinary nursing resulted in better clinical outcomes and treatment efficiency in the patients in the study group versus standardized early rehabilitation nursing. When compared with the control group, the patients in the study group showed lower National Institute of Health Stroke Scale (NIHSS) scores, higher Barthel Index (BI) scores, lower fasting blood glucose levels and body temperature 24 hours after admission, a lower incidence of swallowing dysfunction and aspiration pneumonia 30 days after nursing, and lower C-reactive Protein (CRP) levels 7 days after nursing. The NIHSS scores of the high blood glucose group were significantly higher than those of the normal blood glucose group.

Conclusion

Multidisciplinary nursing based on fever, blood sugar, and swallowing function management for patients with AS improves the clinical outcome and treatment efficiency, restores the swallowing function and blood glucose level, and ameliorates the long-term prognosis of patients.

Impact of septic cerebral embolism on prognosis and therapeutic strategies of infective endocarditis: a retrospective study in a surgical centre

Background

Infective endocarditis still has high mortality and invalidating complications, such as cerebral embolism. The best strategies to prevent and manage neurologic complications remain uncertain. This study aimed to identify predictors of cerebral septic embolism and evaluate the role of surgery in these patients in a real-world surgical centre.

Methods

We retrospectively analyzed 551 consecutive patients admitted to our department with a definite diagnosis of non-device-related infective endocarditis; of these, 126 (23%) presented a neurologic complication.

Results

Cerebral embolism was significantly more frequent in patients with large vegetations (p = 0.004), mitral valve infection (p = 0.001), and Staphylococcus aureus infection (p = 0.025). At multivariable analysis, only vegetation length was an independent predictor of cerebral embolism (HR per unit 1.057, 95% CI 1.025–1.091, p 0.001), with a best predictive threshold of 10 mm at ROC curve analysis (AUC 0.54, p = 0.001). Patients with neurologic complications were more often excluded from surgery despite an indication to it (16% vs 8%, p = 0.001). If eligible, they were treated within two weeks from diagnosis in similar proportions as patients without cerebral embolism with a similar survival rate. Predictors of mortality were hemorrhagic lesions (p = 0.018), a GCS < 14 (p = 0.001) or a severe degree of disability (p = 0.001) at presentation. The latter was the only independent predictor of mortality at multivariable analysis (HR 2.3, 95% CI 1.43–3.80, p = 0.001).

Conclusions

The present study highlights the prognostic value of functional presentation and the safety of cardiac surgery, when feasible, in patients with cerebral septic embolism.

Effect of Acupuncture and Rehabilitation Therapy on the Recovery of Neurological Function and Prognosis of Stroke Patients

BACKGROUND

Stroke is a common cerebrovascular disease among the middle-aged and elderly, which can lead to a series of neurological disorders. Acupuncture is an important part of traditional Chinese medicine, with great value in improving the neurological deficits of stroke patients. In addition, rehabilitation therapy is also of great significance for alleviating the neurological deficits of patients and improving their activities of daily living.

OBJECTIVE

To explore the effect of acupuncture and moxibustion combined with rehabilitation therapy on the recovery of neurological function and prognosis of stroke patients.

METHODS

The case data of 100 stroke patients treated in the Wuhan Hospital of Traditional Chinese Medicine from January 2019 to July 2021 were analyzed retrospectively. According to the treatment plan patients received, they were divided into the following two groups: an observation group (n = 52) treated with acupuncture combined with rehabilitation therapy and a control group (n = 48) treated with rehabilitation therapy alone. The two groups were compared in terms of the following items: therapeutic efficacy, plasma levels of cortisol (Cor) and neuropeptide Y (NPY), nerve function, motor function, balance ability, self-care ability, swallowing function, negative emotions, and quality of life.

RESULTS

The therapeutic effect of the observation group was significantly higher than that of the control group (P < 0.05). The levels of Cor and NPY, as well as the neurological function, motor function, balance ability, self-care ability, swallowing function, and negative emotions, were not significantly different between the two groups before treatment (P > 0.05). While after intervention, all the above indexes improved in both groups, with better improvements in the observation group compared with the control group (P < 0.05). And the various dimensions concerning the quality of life of patients were also significantly better in the observation group when compared with the control group.

CONCLUSION

Acupuncture of traditional Chinese medicine combined with rehabilitation therapy has outstanding effects in stroke treatment and can effectively improve the neurological function, prognosis, and quality of life of patients, which is worthy of clinical promotion.

Functional Independence and Disability Evaluation in Stroke Patients: Optimal Cutoff Scores for a Pictorial-Based Longshi Scale, Barthel Index, and Modified Rankin Scale

Introduction

The modified Rankin Scale (mRS) and Barthel Index (BI) are widely used to measure functional outcomes worldwide. The Longshi Scale (LS), a novel pictorial-based instrument, was designed to improve the simplicity and convenience of measuring functional outcomes in the Chinese context. However, the disagreements in functional outcomes assessed by the mRS, BI, and LS are misleading, particularly in stroke patients. This study aimed to identify the optimal cutoff scores of LS and BI according to the mRS in Chinese stroke patients with different levels of functional disability.

Methods

The mRS, BI, and LS were applied to evaluate functional independence and disability in 7364 stroke patients in a multi-center cross-sectional study. Stroke patients were categorized into bedridden, domestic, and community groups in advance using the LS, indicating severe, moderate, and mild functional disability, respectively. The optimal cut-off scores of the LS and BI according to the mRS were identified via sensitivity, specificity, and Youden's index and stratified by different levels of functional disability determined by LS. We also plotted the receiver operator characteristic (ROC) curves of sensitivity and specificity and determined the area under the curve (AUC).

Results

In the bedridden group, LS and BI cutoff scores with the highest Youden's index were 5 and 10 for mRS 4, and the AUCs for the ROC curve were 0.848 and 0.863 for mRS 4. In the domestic group, LS and BI cutoff scores with the highest Youden's index were 5 and 65 for mRS 3, and the AUCs for the ROC curve were 0.796 and 0.826 for mRS 3. In the community group, LS cutoff scores with the highest sum of sensitivity and specificity were 9, 9, and 8 for mRS grades 0, 1, and 2, respectively, while the BI cutoff scores with the highest sum of sensitivity and specificity were 100, 100, and 95, respectively, while the AUCs for the ROC curve were 0.697 and 0.735 for mRS 2, 0.694 and 0.716 for mRS 1, and 0.628, and 0.660 for mRS 0.

Conclusions

The mRS is more precise to determine mild functional disability, whereas BI can provide more specific information on moderate and severe levels in stroke patients. Although LS was a less precise was to determine moderate and severe levels than BI, it is much simpler and more convenient to be applied to a large-scale population.

Research on Rehabilitation Effect Prediction for Patients with SCI Based on Machine Learning

OBJECTIVE

Due to the complex condition of Spinal Cord Injury (SCI) patients, it is difficult to accurately calculate the Activity of Daily Living (ADL) score of discharged patients. In view of the above problem, this research proposes a prediction model of discharged ADL score based on machine learning, in order to get the rehabilitation effect of patients after rehabilitation training.

METHODS

Firstly, the medical records of 1231 SCI patients were collected, and the corresponding data preprocessing was carried out. Secondly, Pearson Correlation Coefficient method (PCC) was combined with feature selection method based on Random Forest (RF) to screen out six features closely related to discharged ADL score. Then RF and RF optimized by Harris Hawks Optimizer (HHO-RF) were used to predict discharged ADL score of SCI patients. The Mean Absolute Error (MAE), Root Mean Squared Error (RMSE) and Coefficient of determination () were used as evaluation indicators of the model.

RESULTS

The prediction features selected by feature extraction were ADL score on admission, age, injury segment, injury reason, injury position, and injury degree. After 10-fold cross-validation, MAE, RMSE and of RF were 0.0875, 0.1346 and 0.7662. MAE, RMSE and of HHO-RF were 0.0821, 0.1089 and 0.8537. The prediction effect of HHO-RF has been greatly improved.

CONCLUSIONS

In clinical treatment, HHO-RF can accurately predict discharged ADL score and provide a reasonable direction for patients to choose rehabilitation programs.

Endovascular Thrombectomy preceded by intravenous Alteplase versus endovascular Thrombectomy alone in Han Chinese patients treated for acute ischemic stroke with large vessel occlusion: a single-center retrospective analysis

BACKGROUND

The American Heart Association/ American Stroke Association and the Chinese Stroke Association guidelines are recommending intravenous alteplase intervention before endovascular thrombectomy if patients are eligible to do so but the benefits of endovascular thrombectomy are different in Chinese patients with stroke than those of the white patients. The objective of the study was to compare outcomes of patients with acute ischemic stroke treated with endovascular thrombectomy with intravenous alteplase against those treated with endovascular thrombectomy alone.

METHODS

A report is a retrospective analysis of comparing demographics, imaging, clinical and adverse outcomes in the Han Chinese patient who underwent mechanical thrombectomy for acute ischemic stroke with large vessel occlusion, with or without preceding intravenous alteplase administration. Patients with terminus and non-terminus intracranial occlusions and ≤ 2 points neurologic deficit underwent endovascular thrombectomy preceded by 0.9 mg/ kg intravenous alteplase (ET cohort, n = 184) and those who had contra-indication for intravenous alteplase were treated with endovascular thrombectomy alone (EA cohort, n = 141).

RESULTS

The most common procedural complications were embolization into new territory (p = 0.866) and uneventful artery vasospasm (p = 0.712). Insignificant differences were reported for any procedural complications (p = 0.991), imaging outcomes, the modified Rankin scale score (p = 0.663), and death (28 vs. 24, p = 0.761) within 90 days between patients of both cohorts. At the discharge of the hospital, the National Institutes of Health Stroke Scale scores of patients of the ET cohort were lower than those of the EA cohort (8.58 ± 3.79 vs. 10.23 ± 4.97, p = 0.003). The Barthel Index of survivors at 90 days after endovascular thrombectomy was higher for patients of the ET cohort than those of the EA cohort (87.47 ± 12.58 vs. 84.01 ± 13.47, p = 0.032). The most common adverse effect was asymptomatic intracranial hemorrhage (p = 0.297). Insignificant differences were reported for adverse effects after thrombectomy between survivors of both cohorts.

CONCLUSIONS

Outcome measures in Han Chinese patients with acute ischemic stroke treated with endovascular thrombectomy alone were statistically the same as those treated with endovascular thrombectomy plus intravenous alteplase.

Correlation between bispectral index and prognosis of patients with acute cerebral infarction

INTRODUCTION

This study aimed to investigate the clinical value of bispectral index (BIS) monitoring in assessing the consciousness and prognosis of acute cerebral infarction (ACI) patients.

METHODS

In total, 64 patients who suffered from ACI with consciousness disturbance were enrolled in this study. Glasgow Coma Scale (GCS) was performed to evaluate the consciousness level of ACI patients, and BIS was used to monitor the depth of anesthesia and sedation. Then, patients were divided into good prognosis, poor prognosis and death groups according to modified Rankin score (mRS). Discrimination analysis of BIS values and GCS score for the prediction of prognosis was performed using the receiver operator characteristic (ROC) curve.

RESULTS

GCS score and BIS values showed statistically significant differences among the three groups. Spearman rank correlation analysis revealed a significant positive correlation between BIS values and GCS score, while BIS values was negatively related with mRS. The ROC curve of prognosis prediction showed strong prognostic power, with area under the curves (AUCs) between 0.830 and 0.917. Moreover, the AUC of BISmean score was higher than that of BISmax, BISmin and GCS, and BISmean of 74 was the best cut-off point for good prognosis.

CONCLUSION

BIS directly reflects the degree of consciousness disturbance in ACI patients, and thus accurately predicts the prognosis, indicating potential application values of BIS in clinical practice.

Emerging Concepts in Vascular Dementia: A Review

OBJECTIVE

Vascular dementia (VaD) is the second most common cause of dementia and a major health concern worldwide. A comprehensive review on VaD is warranted for better understanding and guidance for the practitioner. We provide an updated overview of the epidemiology, pathophysiological mechanisms, neuroimaging patterns as well as current diagnostic and therapeutic approaches.

MATERIALS AND METHODS

A narrative review of current literature in VaD was performed based on publications from the database of PubMed, Scopus and Google Scholar up to January, 2021.

RESULTS

VaD can be the result of ischemic or hemorrhagic tissue injury in a particular region of the brain which translates into clinically significant cognitive impairment. For example, a cerebral infarct in the speech area of the dominant hemisphere would translate into clinically significant impairment as would involvement of projection pathways such as the arcuate fasciculus. Specific involvement of the angular gyrus of the dominant hemisphere, with resultant Gerstman's syndrome, could have a pronounced effect on functional ability despite being termed a "minor stroke". Small vessel cerebrovascular disease can have a cumulate effect on cognitive function over time. It is unfortunately well recognized that "good" functional recovery in acute ischemic or haemorrhagic stroke, including subarachnoid haemorrhage, does not necessarily translate into good cognitive recovery. The victim may often be left unable to have gainful employment, drive a car safely or handle their affairs independently.

CONCLUSIONS

This review should serve as a compendium of updated information on VaD and provide guidance in terms of newer diagnostic and potential therapeutic approaches.

Stroke outcome assessment: Optimizing cutoff scores for the Longshi Scale, modified Rankin Scale and Barthel Index

The Longshi Scale, a visual-based scale, is reliable and valid in activity assessment, but lacks cutoff definition corresponding to classical scales such as the modified Rankin Scale and Barthel Index. Therefore, this study aimed to investigate the relationships of the Longshi Scale with the modified Rankin Scale and Barthel Index and optimize cutoff scores of these scales in stroke outcomes assessment. This is a cross-sectional study. Stroke patients were measured concurrently by the Longshi scale, modified Rankin Scale and Barthel Index. Kruskal-Wallis test and Spearman correlation analysis were used to analyze the differences and associations among the three scales. The receiver operating characteristic curve was performed to determine the optimal cutoff scores. A total of 5475 stroke patients (67.3% ischemic) were included in this study. There are close relationships of the Longshi Scale with adjusted modified Rankin Scale and Barthel Index (r = -0.861, 0.922; p<0.001, <0.001; respectively). The activity levels assessed by adjusted modified Rankin Scale and Barthel Index among different Longshi scale grades were significantly different (χ2:4217.27, 4676.55; p<0.001, <0.001; respectively). The optimal cutoff scores were adjusted modified Rankin Scale 4, 3, 3, 3, 2 for Longshi scale grade 2 to 6 (sensitivity%: 96.12, 70.24, 89.10, 96.80, 86.23, specificity%: 72.72, 98.29, 93.81, 79.82, 92.89, respectively), and Barthel Index 15, 45, 60, 75, 80 for Longshi scale grade 2 to 6 (sensitivity%: 92.54, 89.28, 91.32, 90.30, 95.65, specificity%: 95.48, 89.51, 94.02, 90.41, 90.62, respectively). In conclusion, the classification of Longshi Scale is consistent with those of modified Rankin Scale and Barthel Index. We recommend the Longshi Scale as an effective supplement for modified Rankin Scale and Barthel Index in assessing the outcome in acute stroke patients.
