Background: Stroke is a severe complication of infective endocarditis (IE), associated with high rates of mortality. Data on how IE patients with and without stroke differ may help to improve understanding contributing mechanisms. Methods: All patients treated for IE between 2019 and 2021 with and without associated stroke were identified from the medical records of three academic tertiary care hospitals in Germany, all part of Charité – Universitätsmedizin Berlin, Germany. Multivariable logistic regression analyses were performed to identify variables associated with the occurrence of stroke. Results: The study population consisted of 353 patients diagnosed with IE. Concomitant stroke occurred in 96/353 (27.2%) patients. Acute stroke was independently associated with co-occurring extracerebral arterial embolism [adjusted Odds ratio (aOR = 2.52; 95% confidence interval (CI) 1.35–4.71)], acute liver failure (aOR = 2.62; 95% CI 1.06–6.50), dental focus of infection (aOR = 3.14; 95% CI 1.21–8.12) and left-sided IE (aOR = 28.26; 95% CI 3.59-222.19). Stroke was found less often in IE patients with congenital heart disease (aOR = 0.20; 95% CI 0.04–0.99) and atypical pathogens isolated from blood culture (aOR = 0.31; 95% CI 0.14–0.72). Conclusions: Stroke is more likely to occur in individuals with systemic complications affecting other organs, too. Special attention should be addressed to dental status. The low incidence of stroke in patients with congenital heart disease may reflect awareness and prophylactic measures. [ABSTRACT FROM AUTHOR]

Sitting ability is an important prognostic factor for patients with acute stroke. However, the characteristics of trunk muscle activity and weight-bearing during sitting are unclear. Are trunk muscle activity and weight-bearing during static sitting associated with sitting ability in patients with acute stroke? Trunk electromyography and sitting posturography were performed during static sitting in 20 patients with acute stroke. The electromyography measured the bilateral external oblique and erector spinae muscles. The symmetry of muscle activity between the paralyzed and non-paralyzed side was calculated using the Symmetry Index (SI) raw value and absolute value. The activity of each muscle during static sitting was calculated as the percent reference voluntary contraction (%RVC) normalized by the maximum contraction in the sitting position. Sitting posturography was used to calculate the weight-bearing pressure (%) on the paralyzed and non-paralyzed side, and the raw and absolute values of weight-bearing SI were calculated as a representative value. The trunk impairment scale (TIS) for sitting ability and the Berg balance scale (BBS) for basic balance ability were used as primary outcomes. None of the SI of electromyography for each trunk muscle correlated significantly with clinical performance tests. The %RVC of paralyzed and non-paralyzed external oblique muscle negatively correlated with TIS. The absolute SI of weight-bearing was negatively correlated with BBS. This study showed that the amount, but not the symmetry, of external oblique muscle activity during sitting was associated with sitting ability. We also found that the symmetry of the weight-bearing was associated with sitting ability, not the direction, but the absolute amount of deviation. This suggests that it is important to focus on the amount of external oblique muscle activity and weight-bearing deviation during sitting as a measure of sitting ability in patients with acute stroke. • External oblique muscle activity during sitting was correlated with sitting balance. • Absolute asymmetry of sitting weight-bearing was correlated with balance ability. • Direction of sitting weight-bearing did not correlate with sitting balance.

Delirium is a common complication in acute stroke patients, occurring in 15–35% of all stroke unit admissions and is associated with prolonged hospital stay and a poor post-stroke prognosis. Managing delirium in acute stroke patients necessitates an intensive and multiprofessional therapeutic approach, placing a significant burden on healthcare staff. However, dedicated practical recommendations for delirium management developed for the population of acute stroke patients are lacking. For this purpose, the Austrian Stroke Society, in cooperation with the Austrian Society of Neurology, the Austrian Society of Neurorehabilitation, and the Austrian Society of Psychiatry, Psychotherapy, and Psychosomatics has formulated an evidence-based position paper addressing the management of delirium in acute stroke patients. The paper outlines practical recommendations on the three pillars of care in stroke patients with delirium: (a) Key aspects of delirium prevention including stroke-specific delirium risk factors and delirium prediction scores are described. Moreover, a non-pharmacological delirium prevention bundle is presented. (b) The paper provides recommendations on timing and frequency of delirium screening to ensure early diagnosis of delirium in acute stroke patients. Moreover, it reports on the use of different delirium screening tools in stroke populations. (c) An overview of non-pharmacological and pharmacological treatment strategies in patients with delirium and acute stroke is presented and summarized as key recommendation statements.

Functional electrical stimulation (FES) can support functional restoration of a paretic limb post-stroke. Hebbian plasticity depends on temporally coinciding pre- and post-synaptic activity. A tight temporal relationship between motor cortical (MC) activity associated with attempted movement and FES-generated visuo-proprioceptive feedback is hypothesized to enhance motor recovery. Using a brain–computer interface (BCI) to classify MC spectral power in electroencephalographic (EEG) signals to trigger FES-delivery with detection of movement attempts improved motor outcomes in chronic stroke patients. We hypothesized that heightened neural plasticity earlier post-stroke would further enhance corticomuscular functional connectivity and motor recovery. We compared subcortical non-dominant hemisphere stroke patients in BCI-FES and Random-FES (FES temporally independent of MC movement attempt detection) groups. The primary outcome measure was the Fugl-Meyer Assessment, Upper Extremity (FMA-UE). We recorded high-density EEG and transcranial magnetic stimulation-induced motor evoked potentials before and after treatment. The BCI group showed greater: FMA-UE improvement; motor evoked potential amplitude; beta oscillatory power and long-range temporal correlation reduction over contralateral MC; and corticomuscular coherence with contralateral MC. These changes are consistent with enhanced post-stroke motor improvement when movement is synchronized with MC activity reflecting attempted movement. [ABSTRACT FROM AUTHOR]

Background: We aim to assess the association between procedural time and outcomes in patients in unsuccessful mechanical thrombectomy (MT) for anterior circulation acute stroke. Methods: We conducted a cohort study on prospectively collected data from patients with M1 and/or M2 segment of middle cerebral artery occlusion with a thrombolysis in cerebral infarction 0–1 at the end of procedure. Primary outcome was 90-day poor outcome. Secondary outcomes were early neurological deterioration (END), symptomatic intracranial hemorrhage (sICH) according to ECASS II and sICH according to SITS-MOST. Results: Among 852 patients, after comparing characteristics of favourable and poor outcome groups, logistic regression analysis showed age (OR: 1.04; 95%CI: 1.02–1.05; p < 0.001), previous TIA/stroke (OR: 0.23; 95%CI: 0.12–0.74; p = 0.009), M1 occlusion (OR: 1.69; 95%CI: 1.13–2.50; p = 0.01), baseline NIHSS (OR: 1.01; 95%CI: 1.06–1.13; p < 0.001) and procedural time (OR:1.00; 95% CI: 1.00–1.01; p = 0.003) as independent predictors poor outcome at 90 days. Concerning secondary outcomes, logistic regression analysis showed NIHSS (OR:0.96; 95%CI: 0.93–0.99; p = 0.008), general anaesthesia (OR:2.59; 95%CI: 1.52–4.40; p < 0.001), procedural time (OR: 1.00; 95% CI: 1.00–1.01; p = 0.002) and intraprocedural complications (OR: 1.89; 95%CI: 1.02–3.52; p = 0.04) as independent predictors of END. Bridging therapy (OR:2.93; 95%CI: 1.21–7.09; p = 0.017) was associated with sICH per SITS-MOST criteria whereas M1 occlusion (OR: 0.35; 95%CI: 0.18–0.69; p = 0.002), bridging therapy (OR: 2.02; 95%CI: 1.07–3.82; p = 0.03) and intraprocedural complications (OR: 5.55; 95%CI: 2.72–11.31; p < 0.001) were independently associated with sICH per ECASS II criteria. No significant association was found between the number of MT attempts and analyzed outcomes. Conclusions: Regardless of the number of MT attempts and intraprocedural complications, procedural time was associated with poor outcome and END. We suggest a deeper consideration of procedural time when treating anterior circulation occlusions refractory to MT. [ABSTRACT FROM AUTHOR]

Introduction: To better target stroke awareness efforts (pre and post first stroke) and thereby decrease the time window for help-seeking, this study aims to assess quantitatively whether stroke awareness is associated with appropriate help-seeking at symptom onset, and to investigate qualitatively why this may (not) be the case. Methods: This study conducted in a German regional stroke network comprises a convergent quantitative-dominant, hypothesis-driven mixed methods design including 462 quantitative patient questionnaires combined with qualitative interviews with 28 patients and seven relatives. Quantitative associations were identified using Pearson's correlation analysis. Open coding was performed on interview transcripts before the quantitative results were used to further focus qualitative analysis. Joint display analysis was conducted to mix data strands. Cooperation with the Patient Council of the Department of Neurology ensured patient involvement in the study. Results: Our hypothesis that stroke awareness would be associated with appropriate help-seeking behaviour at stroke symptom onset was partially supported by the quantitative data, i.e. showing associations between some dimensions of stroke awareness and appropriate help-seeking, but not others. For example, knowing stroke symptoms is correlated with recognising one's own symptoms as stroke (r = 0.101; p = 0.030*; N = 459) but not with no hesitation before calling help (r = 0.003; p = 0.941; N = 457). A previous stroke also makes it more likely to recognise one's own symptoms as stroke (r = 0.114; p = 0.015*; N = 459), but not to be transported by emergency ambulance (r = 0.08; p = 0.872; N = 462) or to arrive at the hospital on time (r = 0.02; p = 0.677; N = 459). Qualitative results showed concordance, discordance or provided potential explanations for quantitative findings. For example, qualitative data showed processes of denial on the part of patients and the important role of relatives in initiating appropriate help-seeking behaviour on patients' behalf. Conclusions: Our study provides insights into the complexities of the decision-making process at stroke symptom onset. As our findings suggest processes of denial and inabilities to translate abstract disease knowledge into correct actions, we recommend to address relatives as potential saviours of loved ones, increased use of specific situational examples (e.g. lying on the bathroom floor) and the involvement of patient representatives in the preparation of informational resources and campaigns. Future research should include mixed methods research from one sample and more attention to potential reporting inconsistencies. [ABSTRACT FROM AUTHOR]

Objective: Acute reperfusion therapy is a critical intervention for stroke patients with the aim of restoring blood flow. The presence of anatomical anomalies, such as fetal posterior cerebral artery (fPCA) and posterior communicating artery (PCOM) variations, can impact treatment outcomes and patient prognosis. This study aimed to assess the potential influence of these anomalies on patients undergoing acute reperfusion therapy. Materials and Methods: Demographic characteristics of patients who underwent acute reperfusion therapy for stroke were considered among three distinct groups: the PCOM group, fPCA group, and control group. The demographic attributes examined for each group included gender distribution, mean age, presence of comorbidities, thrombolysis in cerebral infarction, national institutes of health stroke scale (NIHSS), and European cooperative acute stroke study II (ECASS II) scores. The significance of differences in these attributes among the groups was assessed. Results: The study included a total of 106 patients: 42 patients in the PCOM group, 31 patients in the fPCA group, and 33 patients in the control group. No significant differences in demographic data were observed among the groups. The greatest decrease in NIHSS at the 24th hour was observed in the PCOM group, whereas the least decrease on day 7 was observed in the fPCA group. No differences were detected in the NIHSS values on the 24th hour and 7th day among the groups. When the 24th hour computed tomography scans of the groups were evaluated according to the ECASS II criteria, no significant differences were observed among the groups. Hemorrhage was not observed in 52.4% of patients in the PCOM group and 66.7% of patients in the control group. Conclusion: The impact of fPCA and PCOM anomalies on patients undergoing acute reperfusion therapy for stroke was evaluated. Although no significant demographic differences were found among the groups, the study highlights the importance of further research to better understand their potential impact on treatment outcomes.

Reperfusion therapy, employed in the treatment of acute stroke, frequently proves to be inadequate in addressing the primary brain tissue injury and may even give rise to secondary damage. The study introduces a satellite nanoparticle platform named MEps, which combine the neural repair properties of bone marrow mesenchymal stem cell exosomes (Exos) with the inflammatory site‐targeting abilities of macrophage membranes (MMs). MMs and Exos in MEps act like satellites, ensuring precise positioning and information transmission. MEps rapidly form a protective barrier on the damaged cerebral vascular endothelial cells through the interaction of adhesion molecules with their receptors, blocking the infiltration of neutrophils. Subsequently, repair factors in Exos repair the damaged cells and initiate neurogenesis. The results indicate that this innovative approach effectively mitigates ischemic‐reperfusion injury at multiple levels and demonstrates strong biocompatibility. This strategy holds promise for clinical applications in alleviating ischemic‐reperfusion injury. [ABSTRACT FROM AUTHOR]

Background: Mechanical thrombectomy (MT) has become the mainstay of treatment for acute ischemic stroke (AIS) recently. This case-control study aimed to identify the pivotal role of inflammation in the prognosis of AIS patients after MT. Methods: Altogether, 70 AIS patients who underwent MT were retrospectively recruited for this study. Receiver operating characteristic analysis was performed to demonstrate the sensitivity and specificity of the inflammatory variables for predicting prognosis. A meta-analysis was performed to pool the published results together. Stata software was used for analysis. Results: There was no differences in pre-MT inflammatory biomarkers between patients who survived and those who died, as well as patients with modified Rankin Scale (mRS) 0–2 and mRS ≥ 3. In contrast, post-MT C-reactive protein (CRP) levels might be a potential parameter to predict death after thrombectomy [area under the curve (AUC), 95%confidence interval (CI), 0.737, 0.587–0.887; p = 0.005; optimal cutoff value = 4.565]. Moreover, post-MT monocyte count might be an appropriate parameter to predict poor long-term prognosis after thrombectomy (AUC, 95%CI, 0.704, 0.575–0.833; p = 0.017; optimal cutoff value = 0.345). A meta-analysis revealed that the pre-MT inflammatory indices, including white blood cell count (weighted mean difference, 95%CI, 1.32, 1.01—1.63), neutrophil count (1.23, 0.95—1.51), monocyte count (0.05, 0.02—0.09), neuthrophil-to-lymphocyte ratio (2.42, 1.98—2.87) and platelet-to-lymphocyte ratio (24.65, 7.99—41.32), were higher in patients with 3-month mRS ≥ 3, and the lymphocyte count (−0.31,−0.43 to −0.18) was lower in this cohort. Conclusions: Inflammatory indices were significantly associated with the prognosis of patients undergoing MT, especially post-MT CRP and monocyte count, which can predict long-term outcomes.

Objectives: The purpose of this study was to investigate the preferred modes of transportation to the hospital among patients with acute stroke and acute myocardial infarction (AMI), as well as to identify the factors that influence the utilization of ambulances. Methods: We conducted a cross-sectional study, including patients who were diagnosed with acute stroke and AMI, at the people's hospital of Zhongjiang, from September 30th, 2022 to August 30th, 2023. All patients were divided into emergency medical service (EMS)-activation group and self-transportation group. Chi-square and t-tests were utilized to discern differences between groups at baseline. To screen relevant variables, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis using R package glmnet. Subsequently, we performed a logistic regression analysis to identify predictors of EMS activation according the results of LASSO regression. Results: we collected 929 valid questionnaires. 26.16% of the patients required the services of EMS. 90.9% of individuals have not received any formal first aid education. 42.1% of them reported that they had no understanding of cardiovascular and cerebrovascular diseases. Diagnosed as AMI (OR 0.22, 95%CI 0.06 to 0.88) or acute cerebral infarction (OR 0.26, 0.10 to 0.68), the distance between the patient and the nearest 120 network hospital when the patient had these symptoms (OR 0.97, 0.94 to 0.99), the patient's son or daughter was there when the patient was symptomatic (OR 0.58, 0.37 to 0.94), the patient (OR 0.19, 0.05 to 0.72) and the patient's partner (wife or husband) (OR 0.36, 0.16 to 0.85) had decided that the patient needed further medical help, Among patients who did not seek immediate help after symptom onset, thinking that the symptoms will disappear spontaneously (OR 0.34, 0.13 to 0.92) or not wanting to disturb others (OR 0.06, 0.01 to 0.66) or believing that they are not important symptoms (OR 0.15, 0.05 to 0.42) were factors independently associated with less ambulance use. Age (OR 1.02, 1.00 to 1.04), Stroke patients have experienced symptoms of disturbance of consciousness or convulsions (OR 2.99, 1.72 to 5.2) were independent factors associated with increased ambulance use. Conclusion: There is still ambulance underutilization among patients with acute stroke and AMI in county territory of China. Moreover, it is needed to raise the level of first aid education and awareness about EMS. Additionally, private clinic doctors and the public should gain adequate understanding of the severity of acute stroke and AMI, as well as their common symptoms, the crucial importance of prompt medical intervention. Finally, we propose that all township hospitals should be integrated into the 120 emergency networks and equipped with emergency first aid capabilities, pre-hospital care, and transportation abilities.

Background and Objectives: Dysphagia is a common complication following stroke. It corresponds to the development of pneumonia, which is always associated with bad prognosis, longer hospital stays and increased mortality. The aim of the study was to assess the impact of physical therapy intervention of dysphagia on preventing pneumonia in acute stroke patients. Methods: A single‐blind randomized controlled trial was carried out on 70 ischemic stroke patients with oropharyngeal dysphagia, age ranged from 49 to 65 years. They were randomly assigned to two groups (control and study) of equal number. Patients in the control group received oral care and nasogastric tube feeding, while patients in the study group received the same program in addition to the designed physical therapy program (exercises and neuromuscular electrical stimulation). The intervention program was applied for 40 min/session, 1 session/day, and 5 days/week for 4 weeks. Gugging swallowing screen (GUSS), and stroke associated pneumonia (SAP) control and prevention criteria were used to assess dysphagia and incidence of pneumonia at baseline, after two and 4 weeks of intervention for both groups. Results: Before treatment, all patients were susceptible to pneumonia after two and 4 weeks of intervention; there were a significant increase in GUSS score in both groups with more improvement in favor of the study group (p < 0.05) and a statistically significant increase in incidence of SAP after 2 weeks of intervention only in the control group (p < 0.05). The results also showed a significant negative correlation between GUSS score and SAP (r = − 0.3662, p = 0.0018) Implications for Physiotherapy Practice: adding physical therapy (exercise therapy and neuromuscular electrical stimulation) to oral care and nasogastric tube feeding is effective in improving oropharyngeal dysphagia and decreasing the incidence of aspiration pneumonia in acute ischemic stroke patients.

Background: COVID-19 has significantly increased morbidity and mortality in Indonesia, particularly at Gambiran General Hospital in Kediri, East Java, following the WHO's pandemic declaration. The global incidence of acute stroke with COVID-19 is 1.4%, presenting varying clinical features from mild to severe outcomes, and even death. The identification of specific biomarkers, such as elevated D-dimer serum levels, is crucial for predicting severe complications in acute stroke patients with COVID-19. Objective: This study aimed to explore the correlation between elevated levels of mild, moderate, and severe D-dimer serum and mortality in acute stroke patients with COVID-19. Methods: Conducted as an observational analytical study using a cross-sectional approach, this research utilized secondary data from medical records at Kediri Gambiran General Hospital (March 2020 to June 2023). Inclusion and exclusion criteria were applied to hospitalized patients, categorized based on D-dimer levels: normal, mild, moderate, and severe. Statistical analyses, including the Spearman correlation test and Chi-square correlation test, were employed to assess the relationship between D-dimer levels and total mortality. Results: Among the 101 enrolled patients, 53 were male (52.48%), with 90 exhibiting elevated D-dimer levels. Out of these, 44 patients died. The Spearman correlation test showed a non-significant value of 0.069 (p>0.005). The Chi-square correlation test for mild, moderate, and severe D-dimer levels on total mortality also yielded a non-significant value of 0.878. Conclusion: This study found no significant relationship between elevated levels of mild, moderate, and severe D-dimer serum and mortality in acute stroke patients with COVID-19 at Gambiran General Hospital.

Frailty in older individuals is an underappreciated condition that affects the incidence and/or prognosis of stroke. We evaluated the prevalence of pre-onset frailty in patients with acute first-onset and recurrent strokes and association between pre-onset frailty and functional disability at hospital discharge. This prospective cohort study included 210 acute stroke patients admitted to the Stroke Unit of Nippon Medical School Hospital during November 2021–June 2022. The mean participant age was 79.2 ± 7.4 years. Age, sex, pre-onset frailty, body mass index (BMI), stroke type, medical history, and National Institutes of Health Stroke Scale (NIHSS) score at admission were evaluated. Frailty was defined as a clinical frailty scale (CFS) score ≥ 5. Frailty prevalence was calculated for all patients, and scores of functional disabilities at discharge were evaluated using modified Rankin scale. Overall frailty prevalence was 31% in all stroke patients, with 24% and 47% of first-onset and recurrent strokes, respectively. Pre-onset frailty, NIHSS score at admission, age, stroke type, previous stroke, sex, BMI, dyslipidemia, and atrial fibrillation were significantly associated with functional disability at discharge. Logistic regression analysis revealed that CFS score, NIHSS score at admission, and previous stroke were independent predictors of functional disability at discharge. Approximately one-fourth of patients with first-onset stroke had pre-onset frailty; the rate doubled in recurrent stroke; these rates appear to be much larger than rate in healthy individuals. Pre-onset frailty, a negative independent factor affecting functional disability at discharge, is important for pre-onset frailty evaluation and rehabilitation intervention in acute stroke patients.

Introduction. This study is relevant due to the high prevalence of organic brain pathology and the negative influence of urination disorders on the quality of life.Objective. To analyse the impaired function of lower urinary tracts in patients with organic brain pathology.Materials & methods. We analysed 607 patients with severe organic brain pathology (105 had traumatic spinal cord injury (TSCI) and 457 had consequences of acute stroke (AS)). We performed clinical urological examinations. During the survey, attention was paid to the presence of urinary tract pathology at the examining time and anamnesis. Structural changes in the urinary tract were objectively assessed. We objectively assessed structural changes in urinary tracts including prostate adenoma in men, insufficiency of pelvic floor muscles in women and strictures of the urethra or ureters. The degree of the spastic syndrome was assessed with the Ashworth Scale. The neurourological examination included cystometry with the measurement of bladder volume and post-void residual urine. The cognitive status of the patients was assessed with the MMSE (Mini-Mental State Examination) questionnaire. The correlation analysis between the degree of spastic syndrome measured with the Ashworth Scale and urination disorders was performed with Spearman rank correlation.Results. All patients had neurogenic dysfunction of the lower urinary tract. A combination of bladder retention and emptying disorders was found in 62 men older than 45yo with benign prostate hyperplasia (10,2% of all cases). An impaired accumulation function in history was found in 45 women older than 45yo (7,4% of all observations). The level of spasticity was 3 or 4 points on the Ashworth Scale in patients with TSCI and 2 to 4 points in those with AS. The analysis of correlations between the degree of spasticity and urination disorders showed a moderate relationship (r = 0,4) in patients with TSCI and a medium relationship (r = 0.65) in patients with AS.Conclusion. Neurogenic dysfunction of the lower urinary tract accompanies patients with severe organic brain pathology throughout their life and requires adequate correction.
