Number of Previous Strokes and the Association With Clinical Outcomes of Patients With Atrial Fibrillation: Longitudinal Data From the GLORIA-AF Registry.

Patients with atrial fibrillation (AF) who suffered a previous stroke are at increased risk of recurrent thromboembolic events and other major outcomes. The impact of the number of stroke episodes on the natural history of patients with AF is still unclear. Using data from the international, multicenter, and prospective GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients With Atrial Fibrillation) Registry Phase III, we categorized patients with a recent diagnosis of non-valvular AF according to the number of previous strokes (either 0, 1, or ≥2 episodes). We analyzed use of oral anticoagulants through multiple logistic regression model, and risk of major outcomes using multiple Cox-regression models; our primary outcome was all-cause death. Among 21 223 patients (mean age: 70.2±10.3 years; 44.9% female) included, 2251 (10.6%) had a previous history of stroke, and 216 (1.0%) had ≥2 or more strokes. Oral anticoagulants were used in ≥80% of patients regardless of the numbers of previous stroke, although those with 1 (versus >1) prior stroke showed lower odds of receiving oral anticoagulants (odds ratio [95% CI]: 0.83 [0.73-0.94]). During 3-years follow-up, the risk of all-cause mortality increased with the number of previous strokes (hazard ratio [95% CI]: 1.46 [1.28-1.67] and 2.43 [1.79-3.29] for 1 versus 0 and ≥2 versus 0 previous strokes, respectively). Similar results were observed for other secondary outcomes, including thromboembolism, but not for major bleeding. History of stroke still represents a key risk factor in patients with AF. Patients who suffered more than 1 episodes of stroke had significantly worse prognosis and further efforts may be required to improve their clinical outcomes.

Multiple burr hole and erythropoietin combination therapy: optimal early surgical intervention for patients with acute stroke episode of moyamoya disease or moyamoya syndrome

ObjectiveThe optimal timing of bypass surgery for patients with moyamoya disease (MMD) or moyamoya syndrome (MMS) following an acute stroke episode remains unclear, mainly owing to the risk of postoperative complications. In this study, we aim to validate the safety and efficacy of early intervention using multiple burr hole (MBH) and erythropoietin (EPO) therapy, thereby refining the management strategy for patients with acute stroke episode of MMD or MMS.MethodsWe retrospectively analyzed data from 70 patients with MMD or MMS who underwent MBH and EPO therapy. The cohort was divided based on the time interval between the latest neurological deterioration and surgery: early (<30 days) and later (≥30 days) groups. We evaluated and compared perioperative clinical parameters and the extent of neovascularization on a 6-month postoperative angiography. Long-term clinical outcomes, including transient ischemic attack (TIA), infarction, hemorrhage, and seizure, were also analyzed during the follow-up period.ResultsIn the cohort, 36 patients (51.4%) were in the early group, whereas 34 (48.6%) were in the later group. The 6-month follow-up angiography demonstrated that 34/47 hemispheres (72.3%) in the early group exhibited successful neovascularization (≥2/3 of MCA territories) compared with the 19/44 (43.2%) hemispheres in the later group (odds ratio [OR] = 3.44; 95% confidence interval [CI]: 1.46–8.45; p < 0.01). In addition, a notable reduction (≥50%) in basal moyamoya vessels was observed in 30/47 hemispheres (63.8%) from the early group vs. 12/44 (27.3%) hemispheres from the later group (OR = 4.71; 95% CI: 1.97–11.82; p < 0.001). During the average follow-up of 56.5 months, only six patients experienced infarction or hemorrhage.ConclusionOur dataset suggests that MBH and EPO combination therapy is an effective, minimally invasive, and acceptable treatment, even in the early period of patients with MMD or MMS following an acute stroke episode.

Elucidating the mechanisms of a herbal compound fumarine and its modulation on the estrogen receptor 1

Stroke-related numbness and weakness (SRNW) are resultant disabilities following a stroke episode and may present with muscle weakness, numbness, tightness, spasticity, and pain in up to 85% of patients. Huangqi Guizhi Wuwu Decoction (HGWD) has been widely investigated to manage the sensorimotor deficiencies at the herb and formula level. However, detailed molecular mechanisms of its constituents are presently lacking. This project employed computational molecular modelling and docking methods to identify candidate compounds of HGWD which may serve as effective modulators of target proteins involved in SRNW. Estrogen Receptor 1 was identified as a promising target for HGWD compounds, while the herbal compound fumarine, a constituent of Jujubae Fructus, was predicted to exhibit high binding affinity and favourable ligand-receptor interactions with ESR1. There is currently a lack of scientific evidence for specific atomic-level interactions between ESR1 and this compound. Therefore, molecular docking and molecular dynamics simulations were used to elucidate the interaction mechanisms of fumarine with ESR1; and the molecular-level structural and functional consequences of ligand binding. Ligand-receptor contact analysis and free energy decomposition calculations identified Glu419 and Leu38 as stable hydrogen bond partners, while favourable contributions to the binding free energy include in Met421 (−10.74 kJ/mol) and Leu525 (−10.02 kJ/mol). This work provides the basis for further studies on discovering lead compounds which modulate the activity of ESR1.

Diagnosing Monogenic Stroke at Younger Age.

An increasing number of monogenic conditions underlying stroke are being identified. We explored the possibilities of increasing the diagnostic yield of monogenic stroke in a population under 56 years of age. Fifty probands ≤55 years at their first stroke episode were characterized clinically and investigated by whole genome sequencing. Probands had one or more of: (1) one or more first to second degree relatives with stroke under 60 years or same stroke-causing condition/disease; (2) no hypertension, hypercholesterolemia, diabetes, heart disease, or smoking; or (3) either multiple stroke episodes or multiple arterial dissections. Variants with minor allele frequency under 0.01, identified by using our stroke gene panels, were assessed. The stroke subtypes, including large artery atherosclerotic, large artery nonatherosclerotic (tortuosity, dolichoectasia, aneurysm, nonatherosclerotic dissection, or occlusion), cerebral small vessel disease, cardioembolic (arrhythmia, heart defect, or cardiomyopathy), coagulation dysfunctions (venous thrombosis, arterial thrombosis, or bleeding tendency), intracerebral hemorrhage, vascular malformations (cavernoma or arteriovenous malformations), metabolic disorders, or cryptogenic embolic, were used for genotype-phenotype correlation. In a final step, we combined genetic and clinical information to determine if the genetic variant likely was the cause of stroke in the patients. Whole genome sequencing of younger patients with stroke identified 17 clinically matching genetic variants in 15 of 50 (30%) patients, while a stronger clinical correlation with stroke was established in only 6 (12%) of them. Stroke-related genetic variants were identified in 4 of 5 (80%) patients with cardioembolic stroke subtype, 3 of 4 (75%) with intracerebral hemorrhage, 7 of 18 (39%) with cryptogenic embolic stroke, 1 of 6 (17%) with small vessel disease, and 3 of 15 (20%) of patients with nonatherosclerotic large artery stroke, including 1 of 11 (9%) with cervical dissection stroke. Careful clinical interpretation of whole genome data using stroke gene panels can detect monogenic causes of early stroke, allowing individualized follow-up and opening new possibilities for potential treatment.

Post-stroke fatigue and its correlation with family functioning in patients who have experienced a first episode of stroke.

This study aimed to analyse the relevant factors that may affect post-stroke fatigue (PSF) in patients with stroke and further explore the correlation between family functioning and PSF. Patients who had experienced a first episode of stroke and were admitted to the Department of Neurology of the First Affiliated Hospital of Wenzhou Medical University were rigorously screened. The general data and family functioning of the patients on admission were collected, and their family adaptation, partnership, growth, affection and resolve scores and their PSF on the 5th day of admission were collected using the fatigue severity scale (FSS). Multiple linear regression analysis was then utilized to explore the factors affecting PSF in patients with stroke. A total of 220 questionnaires were distributed, and 220 were returned, with 212 valid questionnaires and a valid return rate of 96.4%. These 212 patients had a family functioning score of 6.58 ± 2.00 and an FSS score of 36.62 ± 10.96. Spearman's correlation analysis showed negative correlations between the FSS scores and the adaptation, partnership, growth, affection, resolve and family functioning scores (r = -0.380, -0.505, -0.470, -0.303, -0.281 and -0.712, respectively; p < 0.001). Furthermore, multiple linear regression analysis showed that family functioning (β' = -0.516), marital status (β' = -0.244), household income (β' = -0.185), literacy (β' = -0.181) and activities of daily living (β' = -0.084) were influential factors for PSF in patients with stroke (p < 0.05). There is a significant negative correlation between family functioning and PSF, suggesting that better family functioning may help mitigate the severity of post-stroke fatigue. Healthcare providers should identify interventions to help patients and families address fatigue, boost disease recovery, promote patients' physical and mental health and improve their quality of life.

Blended Phenotype of NOTCH3 and RNF213 Variants With Accelerated Large and Small Artery Crosstalk: A Case Report and Literature Review.

Recent advancements in genome research have revealed not only the importance of variants associated with cerebrovascular diseases but also a notably high frequency of carriers harboring multiple variants, presenting with an elusive blended phenotype. In this study, we report the case of a 66-year-old man who experienced 3 stroke episodes over a 4-year period, starting at the age of 62 years. The patient presented with isolated infarcts in the left temporal pole with progressive stenosis in the ipsilateral middle cerebral artery based on large and small artery crosstalk. Exons 2-24 of the NOTCH3 gene were analyzed by direct genomic DNA sequencing. The presence of the p.Arg4810Lys variant of the ring finger protein 213 (RNF213) gene was evaluated using real-time PCR. Diagnoses of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy and RNF213-related vasculopathy were made based on the early-onset recurrent stroke episode, progressive intracranial artery stenosis, and presence of the heterozygous NOTCH3 p.Cys1250Arg and RNF213 p.Arg4810Lys variants. Temporal pole infarcts could represent a blended phenotype of both variants. This case highlights the importance of large and small artery crosstalk and the pivotal role of genetic analysis in determining the pathogenesis of stroke and dementia.

Quantifying and Assessing Post-Stroke Patients' Functional Capability Level for Independent Daily Activities: A Review

Every year, over 13.7 million stroke episodes occur worldwide, addressing the pressing need for efficient rehabilitation treatments to restore motor function in stroke patients is paramount. The escalating number of stroke cases emphasises the urgency of developing robust rehabilitation methodologies. Currently, therapists rely on subjective and manual assessments to determine subsequent patient interventions, a method fraught with challenges, including subjectivity and dependence on the therapist's experience. This paper critically reviews the quantification and assessment of post-stroke patients' functional capability for independent daily activities. It delves into the existing standards of clinical assessment, explores the integration of sensors in limb rehabilitation prototypes, and observes the mathematical methods and algorithms employed by previous researchers to assess and quantify stroke patients' functional capability automatically. The discussion covers the advantages and disadvantages encountered in developing these prototypes and evaluating their suitability in addressing the complexities of stroke rehabilitation. In conclusion, this paper provides a perception of existing research and identifies crucial gaps. Based on the current research landscape, it presents proposals for prototype development, paving the way for future advancements in stroke rehabilitation methodologies.

Medication prescribing trends and its associated adverse drug reactions among hospitalized stroke patients from a main stroke center in Penang, Malaysia: A retrospective 5-year study

Adverse drug reactions (ADRs) are one of the major threats in our healthcare system, which profusely affects health, transience, and quality of life, especially among hospitalized patients. This 5-year study was conducted to determine the incidence and analyze the pattern of ADRs among stroke patients at Hospital Seberang Jaya (HSJ), Malaysia which is the main stroke center for all tertiary healthcare institutions in Penang, Malaysia. A total of 1,993 patients were hospitalized for stroke during the study period of 5 years out of which only 30 of them were reported to experience ADRs during hospitalization. The study patients had a mean (SD) of 61 (±11.8) years, Modified Rankin Score (mRS) score of 1.8 (±1.6), NIH Stroke Scale (NIHSS) score of 3.0 (4.0) with median (IQR) duration of adverse drug reaction of 3.0 (7.0) days. The majority of the patients were Malay (66.7%); female (50.0%); experienced ischemic stroke (90.0%); with first episode of stroke (93.3%); with comorbidity dyslipidemia (60.0%); and mostly recovered post ADRs (80.0%). The major drug classes that contributed to ADRs were vaccines, anti-infective, anti-epileptic, anti-platelets, and others. Evaluation of the causality of ADRs indicated majority were possible (50.0%) ADRs based on the Naranjo scale. The evaluated incidence of ADRs among stroke patients is low in this study. This low incidence rate could be possibly due to active clinical interventions by healthcare professionals during hospitalization. ADR monitoring is highly warranted among the sub-population of stroke patients due to the existence of multiple risk factors and their state of vulnerability.

Assessment of Health-Related Quality of Life of Stroke Survivors in Southeast Communities in Nigeria.

The prevalence of stroke in Nigeria has continued to be a major public health challenge. Recovery from a stroke episode can be a long-impacting process with reduced quality of life outcomes. Past studies have explored the quality of life (QoL) of stroke survivors. However, none have explored the QoL of stroke survivors in Southeastern Nigeria. This study therefore describes the QoL of Nigerian stroke survivors in Southeastern Nigeria. One hundred and one participants (44 male and 58 female) were recruited into the study. QoL domains were assessed using the stroke-specific Health-Related Quality of Life in Stroke Patients (HRQOLISP). The physical domain was significantly lower than other domains measured (mean = 2.52, SD = 0.76), contributing to poor quality of life. On the other hand, the spiritual domain had the greatest positive influence on QoL (mean = 3.70, SD = 0.50). We found the physical domain was the poorest part of stroke survivors' stroke experience. The spiritual domain had a positive impact on improving QoL. There is a need for research on interventions relating to the physical rehabilitation of stroke survivors and a review of how the spiritual domain can be enhanced to improve QoL.

Constipation is associated with an increased risk of major adverse cardiac events in a UK population.

Traditional cardiovascular risk factors, including hypertension, only explain part of major adverse cardiac events (MACEs). Understanding what other risk factors contribute to MACE is essential for prevention. Constipation shares common risk factors with hypertension and is associated with an increased risk of several cardiovascular diseases. We hypothesized that constipation is an underappreciated risk factor for MACE. We used the population healthcare and genomic data in the UK Biobank (n = 408,354) to study the contribution of constipation (ICD10 K59.0) to the risk of MACE, defined by any episode of acute coronary syndrome (ACS), ischemic stroke, and heart failure (HF). Analyses were controlled for traditional cardiovascular risk factors. We also assessed genetic correlations (rg) between constipation and MACE. Constipation cases (n = 23,814) exhibited a significantly higher risk of MACE compared with those with normal bowel habits [odds ratio (OR) = 2.15, P < 1.00 × 10-300]. Constipation was also significantly associated with individual MACE subgroups, in order: HF (OR = 2.72, P < 1.00 × 10-300), ischemic stroke (OR = 2.36, P = 2.02 × 10-230), and ACS (OR = 1.62, P = 5.82 × 10-113). In comparison with patients with constipation-free hypertension, patients with hypertension with constipation showed significantly higher odds of MACE (OR = 1.68, P = 1.05 × 10-136) and a 34% increased risk of MACE occurrence (P = 2.3 × 10-50) after adjustment for medications that affect gut motility and other traditional cardiovascular risk factors. Finally, we detected positive genetic correlations between constipation and MACE subgroups ACS (rg = 0.27, P = 2.12 × 10-6), ischemic stroke (rg = 0.23, P = 0.011), and HF (rg = 0.21, P = 0.0062). We identified constipation as a potential risk factor independently associated with higher MACE prevalence. These findings warrant further studies on their causal relationship and identification of pathophysiological mechanisms.NEW & NOTEWORTHY Analyzing 408,354 participants of the UK Biobank, we show that constipation cases exhibited a significantly higher risk of major adverse cardiac events (MACEs) than those with regular bowel habits. In comparison with patients with constipation-free hypertension, patients with hypertension with constipation showed significantly higher odds of MACE and a 34% increased risk of subsequent MACE occurrence. Finally, we detected positive genetic correlations between constipation and MACE. This association holds potential for therapeutic exploitation and prevention based on individuals' risk assessment.

Hospital–Skilled Nursing Facility Integration and Participation in a Bundled Payment Initiative

Reduced institutional postacute care has been associated with savings in alternative payment models. However, organizations may avoid voluntary participation if participation could threaten their own revenues. To characterize the association between hospital-skilled nursing facility (SNF) integration and participation in Medicare's Bundled Payments for Care Improvement Advanced (BPCI-A) program. This is a cross-sectional analysis of hospital participation in BPCI-A beginning with its launch in 2018. Each SNF-integrated hospital was matched with 2 nonintegrated hospitals for each of 4 episode-specific analyses. Fifteen hospital-level variables were used for matching: beds, case mix index, days, area SNF beds, metropolitan location, ownership, region, system membership, and teaching status. Hospitals were also matched on episode-specific volume, target price, and the interaction of target price and case mix. Episode-specific logistic models were estimated regressing hospital participation on integration and the previously listed variables. The marginal effect of integration on participation was then calculated. Analysis took place from August 2022 to May 2024. Hospital-SNF integration, as defined by common ownership and referral patterns and identified using cost reports, Medicare claims, and Provider Enrollment, Chain, and Ownership System records. Additional sources included records of target prices and participation, the Area Health Resources File, and the Compendium of US Health Systems. Participation in BPCI-A. In total, 1524 hospitals met criteria for inclusion in the hip and femur (HFP) analysis, 1825 were included in the major joint replacement of the lower extremity (MJRLE) analysis, 2018 were included in the sepsis analysis, and 1564, were included in the stroke-specific analysis. Across episodes, 191 HFP-eligible hospitals (12.5% of HFP-eligible hospitals), 302 MJRLE-eligible hospitals (16.5%), 327 sepsis-eligible hospitals (16.2%), and 185 sepsis-eligible hospitals (11.8%) were SNF integrated. In total, 79 hospitals (5.2%) participated in the HFP episode, 128 (7.0%) participated in the MJRLE episode, 204 (10.1%) participated in the sepsis episode, and 141 (9.0%) participated in the stroke episode. Integration was associated with a 4.7-percentage point decrease (95% CI, 2.4 to 6.9 percentage points) in participation in the MJRLE episode. There was no association between integration and participation for HFP (0.5-percentage point increase in participation moving from nonintegrated to integrated; 95% CI, -2.9 to 3.8 percentage points), sepsis (1.0-percentage point increase; 95% CI, -2.2 to 4.2 percentage points), and stroke (0.3-percentage point decrease; 95% CI, -3.1 to 3.8 percentage points). In this cross-sectional study, there was an uneven association between hospital-SNF integration and participation in Medicare's BPCI-A program. Other factors may be more consistent determinants of selection into voluntary payment reform.

An Integrated Multi-omics prediction model for stroke recurrence based on [formula omitted] transformer layer and dynamic weighting mechanism

Background and objectiveStroke is a disease with high mortality and disability. Importantly, the fatality rate demonstrates a significant increase among patients afflicted by recurrent strokes compared to those experiencing their initial stroke episode. Currently, the existing research encounters three primary challenges. The first is the lack of a reliable, multi-omics image dataset related to stroke recurrence. The second is how to establish a high-performance feature extraction model and eliminate noise from continuous magnetic resonance imaging (MRI) data. The third is how to integration multi-omics data and dynamically weighted for different omics data. MethodsWe systematically compiled MRI and conventional detection data from a cohort comprising 737 stroke patients and established PSTSZC, a multi-omics dataset for predicting stroke recurrence. We introduced the first-ever Integrated Multi-omics Prediction Model for Stroke Recurrence, MPSR, which is based on ResNet, Lnet-transformer, LSTM and dynamically weighted DNN. The MPSR model comprises two principal modules, the Feature Extraction Module, and the Integrated Multi-Omics Prediction Module. In the Feature Extraction module, we proposed a novel Lnet regularization layer, which effectively addresses noise issues in MRI data. In the Integrated Multi-omics Prediction Module, we propose a dynamic weighted mechanism based on evaluators, which mitigates the noise impact brought about by low-performance omics. ResultsWe compared seven single-omics models and six state-of-the-art multi-omics stroke recurrence models. The experimental results demonstrate that the MPSR model exhibited superior performance. The accuracy, AUROC, specificity, and sensitivity of the MPSR model can reach 0.96, 0.97, 1, and 0.94, respectively, which is higher than the results of contrast model. ConclusionMPSR is the first available high-performance multi-omics prediction model for stroke recurrence. We assert that the MPSR model holds the potential to function as a valuable tool in assisting clinicians in accurately diagnosing individuals with a predisposition to stroke recurrence.

The Effects of mirror therapy in postural and kinesthetic rehabilitation on stance phase of gait in subacute stroke

Background: This study explored the effectiveness of mirror therapy in improving postural and kinesthetic rehabilitation during the stance phase of gait in subacute stroke patients. Given the crucial role of balance and functional recovery in enhancing mobility and overall quality of life in stroke survivors, the primary focus was on these aspects. Objective: The primary objective was to evaluate the impacts of mirror therapy on postural and kinesthetic rehabilitation during the stance phase of gait in subacute stroke patients. Methods: A randomized controlled trial was conducted over nine months in Rahim Yar Khan, involving both private and government hospitals. Sixty-four participants were randomly assigned to two groups: the Conventional+KTR group and the Mirror Therapy group, with 32 participants in each. Inclusion criteria required participants to have a single episode of hemiplegic subacute stroke diagnosed by a neurologist, inclusion of both ischemic and hemorrhagic stroke, and sufficient cognitive ability to follow instructions as indicated by a Mini-Mental State Examination (MMSE) score of 24 or higher. Mild spasticity in all joints of the affected limb was defined by a Modified Ashworth Scale score of less than 3. The intervention for the experimental group involved mirror therapy conducted four days a week for six weeks, supplemented by a home plan for the remaining three days. The control group received conventional therapy, including proprioceptive neuromuscular facilitation (PNF) and electrical interventions, also for four days a week, with a home plan for the remaining days. Key outcome measures were the Berg Balance Scale (BBS) for balance and the Fugl-Meyer Assessment for functional recovery. Data were analyzed using SPSS Version 25, with significance set at p&lt;0.05. Results: The Mirror Therapy group showed significantly greater improvements in balance scores, with a mean BBS of 40.31 at week 6 compared to 36.78 in the Conventional+KTR group (p&lt;0.001). Functional recovery was more pronounced in the Conventional+KTR group, which had a mean Fugl-Meyer Assessment score of 35.63 at week 6 compared to 30.50 in the Mirror Therapy group (p&lt;0.001). Gender distribution was similar across both groups, with the Conventional+KTR group consisting of 21.9% males and 78.1% females, and the Mirror Therapy group having 18.8% males and 81.3% females. Conclusion: Mirror therapy significantly enhances postural and kinesthetic rehabilitation in subacute stroke patients, particularly in improving balance more effectively than Conventional+KTR therapy. Conversely, Conventional+KTR therapy showed better results in functional recovery. These findings suggest that mirror therapy can be a valuable addition to stroke rehabilitation programs, offering a potential avenue for improved patient outcomes.

Stroke and Stroke-Like Episodes: Recurrent Manifestations in GLUT1 Deficiency Syndrome

BackgroundSince the initial description of glucose transporter-1 deficiency syndrome (Glut1-DS) the phenotype of the condition has expanded, even leading to the recognition of atypical manifestations. We report on eight patients with Glut1-DS who experienced at least one episode of acute focal neurological deficits. MethodsWe conducted a retrospective analysis, collecting clinical, electrophysiological, neuroradiological, and genetic information. We focused in particular on three well-documented cases. ResultsAmong 42 patients with Glut1-DS, eight individuals aged between six and 38 years presented with an acute onset of neurological disturbances: dysarthria/aphasia, oral dyskinesia, swallowing difficulties, paresthesia, facial palsy, hemi/monoplegia, vomiting, headache, and behavioral disturbances. When performed, magnetic resonance imaging (MRI) revealed signs of venous congestion and hypoperfusion and electroencephalography showed focal contralateral slowing. Deficits were transient in all patients but one. Four patients (50%) were on a ketogenic diet (KD), and two of these patients had lower than usual ketonemia levels during the episode. In two patients, MRI demonstrated the presence of an ischemic brain lesion. ConclusionsIn Glut1-DS, stroke-like episodes are a recurrent manifestation, particularly during early adulthood, and they were reported in 19% of the patients in our cohort. Stroke mimics should be considered a key feature of Glut1-DS, as other paroxysmal disorders. It remains to be established whether a KD can prevent the recurrence of episodes and, if so, at what level of ketosis. Further observations are needed to confirm the correlation between Glut1-DS and ischemic stroke.

Predictors of 30-day mortality following the first episode of stroke among patients admitted at referral hospitals in Dodoma, central Tanzania: A prospective longitudinal observational study.

Stroke is the leading cause of disability and the second most common cause of death after ischemic heart disease worldwide. Understanding predictors of early poststroke mortality provides opportunities for interventions and favorable outcomes. This study aimed to determine the incidence and predictors of 30-day mortality among patients admitted with the first stroke at referral hospitals in Dodoma. A prospective longitudinal observational design enrolled patients with acute stroke confirmed by CT scan or MRI admitted at referral hospitals in Dodoma. The National Institute of Health Stroke Scale was used to assess stroke severity at baseline. A comparison of risk factors, clinical profiles, and mortality was done using the Chi-square test. A logistic regression model was used to determine the predictors of 30-day mortality in patients with the stroke while the 30-day probability of survival was estimated using Kaplan-Meier analysis. Out of 226 patients with first-ever stroke, 121(54%) were males, and the population mean age was 63(15) years. The 140(62%) had Ischemic stroke, and 154(68%) survived at the 30th day. Patients with a history of smoking 2.4 [95% confidence interval (CI) (1.0-5.6), p = 0.048], loss of consciousness 2.7 [95% CI (1.2-6.4; p = 0.019] and unequal pupil size 13.7 [95% CI (4.1-58.1, p < 0.001 were significantly more associated with mortality within 30 days. The median survival was 7 (3-9) days, whereas alcohol drinkers and those aged above 60 years had a shorter time to mortality compared to non-alcohol drinkers and those aged <60 years. The study showed a high incidence of mortality within 30 days after the first stroke episode, with the highest proportion dying within 7 days of being hospitalized. Advanced age of ≥60 years, smoking, alcohol use, and severe stroke at admission warrant special attention.

Effect of a diabetes-specific formula in non-diabetic inpatients with stroke: a randomized controlled trial

Background/objectivesIn patients with acute stroke, the presence of hyperglycaemia has been associated with higher morbidity and less neurological recovery. The aim of the study was to evaluate the impact of a diabetes specific enteral nutrition (EN) formula on glycaemia, comorbidities and mortality in patients admitted with a first episode of stroke who received complete EN.MethodsThis was a prospective randomised controlled trial. Patients with acute stroke did not have diagnosis of diabetes mellitus and required nasogastric tube feeding. This study has been registered with code NCT03422900. The patients were randomised into two arms: an isocaloric isoprotein formula (control group (CG), 27 patients) vs a diabetes-specific formula (low glycaemic index carbohydrates, fibre (80% soluble) and higher lipid content) (experimental group (EG), 25 patients). Pre-EN blood glucose, hyperglycaemia during EN treatment, HbA1c, insulin use, oral route recovery, length of stay (LOS) and mortality at 30 days were collected. The complications of enteral nutrition during admission were collected as well.Results52 patients were included, 50% females, with an age of 77.44(11.48) years; 34 (65.4%) had ischaemic stroke, with a Rankin score of 0(0–2), and a National Institute of Health Stroke Scale (NIHSS) of 19 (15–22). In CG, there were more cases of hyperglycaemia on the 5th day post-NE (13(65%) vs7(35%), p < 0.01). CG showed an OR of 7.58(1.49–39.16) (p = 0.02) for the development of hyperglycaemia. There were no differences in LOS between groups (12(8.5) days vs 14(23) days, p = 0.19) or in the death rate (10(37%) vs 10(40%), p = 0.8), although differences were found in terms of oral route recovery (EG: 11(44%) patients vs CG: 5(18.5%) patients, p = 0.04) (OR (EG): 5.53(1.25–24.47); p = 0.02).ConclusionsThe use of a diabetes-specific enteral formula in non-diabetic patients admitted with acute stroke reduced the risk of developing hyperglycaemia and improved the rate of oral route recovery.Registered under ClinicalTrials.gov Identifier no. NCT03422900.

Impact of an expanded reimbursement policy on utilization of implantable loop recorders in patients with cryptogenic stroke in Korea.

The reimbursement policy for cryptogenic stroke (CS) was expanded in November 2018 from recurrent strokes to the first stroke episode. No reports have demonstrated whether this policy change has affected trends in implantable loop recorder (ILR) utilization. We identified patients who received an ILR implant using the Korea Health Insurance Review and Assessment Service database between July 2016 and October 2021. Patients meeting all the following criteria were considered to have CS indication: 1) prior stroke history, 2) no previous history of atrial fibrillation or flutter (AF/AFL), and 3) no maintenance of oral anticoagulant for ≥4 weeks within a year before ILR implant. AF/AFL diagnosed within 3 years after ILR implant or before ILR removal was considered ILR-driven. Among 3,056 patients, 1,001 (32.8%) had CS indications. The total ILR implant number gradually increased for both CS and non-CS indications and the number of CS indication significantly increased after implementing the expanded reimbursement policy. The detection rate for AF/AFL was 26.3% in CS patients over 3 years, which was significantly higher in patients implanted with an ILR within 2 months after stroke than those implanted later. The expanded coverage policy for CS had a significant impact on the number of ILR implantation for CS indication. The diagnostic yield of ILR for AF/AFL detection seems better when ILR is implanted within 2 months than later. Further investigation is needed to demonstrate other clinical benefits and the optimal ILR implantation timing.

Involvement of P2X7R-mediated microglia polarization and neuroinflammation in the response to electroacupuncture on post-stroke memory impairment

PurposePost-stroke cognitive impairment (PSCI) is a common complication of ischemic stroke episodes. Memory impairment is an important component of the poststroke cognitive syndrome. Microglial activation plays a critical role in stroke-induced neuroinflammation. Previous studies have reported that electroacupuncture (EA) provides neuroprotective effects by reducing the expression levels of the Purinergic receptor P2X ligand-gated ion channel 7 (P2X7) and inhibiting neuroinflammation in rat model of ischemic stroke. Further understanding of the role and connections between P2X7R and microglial activation in EA-induced anti-inflammatory can reveal novel targets for post-stroke memory impairment treatment. MethodsA Middle cerebral artery occlusion and reperfusion (MCAO/R) model was established. We used 2’(3’)-O-(4-benzoyl) benzoyl ATP (BzATP) as a P2X7R agonist. Following MCAO/R injury, the rats underwent EA therapy at the Baihui (DU20) and Shenting (DU24) acupoints for seven consecutive days. The Barnes maze test was used to evaluate memory function. Following intervention, a T2 weighted images (T2WI) scan was performed to identify changes in cerebral infarction volume in MCAO/R rats. The levels of Interleukin-1β (IL-1β), Interleukin-6 (IL-6) and Interleukin-4 (IL-4), Interleukin-10 (IL-10) in the peri-infarct hippocampal were examined by ELISA. Immunofluorescence was employed to evaluate Iba-1+ / P2X7R+, Iba-1+/ iNOS+ and Iba-1+/ Arg-1+ cell populations in the peri-infarct hippocampal DG area. The protein expression of P2X7R, Nuclear factor E2-related factor 2 (Nrf2), Recombinant nlr family, pyrin domain containing protein 3 (NLRP3), Inducible nitric oxide synthase (iNOS) and Arginase-1 (Arg-1) in the peri-infarct hippocampal were investigated using western blot assays. Besides, we also measured the levels of reactive oxygen species (ROS), superoxide dismutase (SOD) and malondialdehyde (MDA). ResultsWe found EA treatment reduced inflammation and oxidative stress, which is consistent with a decrease in P2X7R expression and improved learning and memory functions. In contrast, we found BzATP enhanced inflammation and oxidative stress. Moreover, our results showed EA treatment up-regulated Nrf2, down-regulated NLRP3, and promoted microglia M2 polarization. Finally, EA-mediated positive effects were reversed by intracerebroventricular injection of BzATP, which is consistent with an increase in P2X7R expression. ConclusionEA ameliorates memory impairment in a rat model of ischemic stroke by reducing inflammation and ROS through the inhibition of P2X7R expression. In turn, this mechanism regulates Nrf2 and NLRP3 expression, suggesting EA is beneficial for ischemic stroke treatment using P2X7R as target.

Association of Glycated Hemoglobin With Acute Ischemic Stroke in a Tertiary Care Center in a Tribal Region of Jharkhand.

Increased glycated hemoglobin (HbA1c) levels have shown an association with an increased risk of stroke in patients admitted to a tertiary care center in Jharkhand. To find out and estimate the risk of acute ischemic stroke in patients with increased HbA1c levels compared with controls. This observational case-control study was conducted on patients admitted to the department of general medicine at a tertiary care center in Ranchi from June 2021 to November 2022. The patients included in this study were those aged 18 years or older and who were clinically and radiologically diagnosed with acute ischemic stroke. Only patients with a first episode of stroke were included, and patients with hemorrhagic stroke or transient ischemic attack were excluded from this study. An equal number of control participants were also included. Ion exchange high-performance liquid chromatography was used to perform the HbA1c tests. The same method was used to measure HbA1c levels in the controls. All findings were recorded in aMicrosoft Excel sheet (Microsoft Corporation, Redmond, WA), and the data were analyzed using SPSS version 22.0software (IBM Corp., Armonk, NY). After performing a descriptive statistical analysis, the findings were classified over a range of values and described accordingly. For each variable, an independent t-test was performed to compare the cases with the controls. A multivariable logistic regression analysis was used to choose the appropriate potential factors to determine the association in the multivariable analysis. A total of 185 cases and 185 controls were included. The mean age of the cases with ischemic stroke was 63.77 ± 10.312, and that of the controls was 53.18 ± 11.35 (p < 0.01). The mean HbA1c level in the patients of acute ischemic stroke was 6.97 ± 1.84, and that of the controls was 5.99 ± 1.69 (p < 0.01). The mean random blood sugar (RBS) value in the ischemic stroke cases was 170.21 ± 84.16, and that of the controls was 150.03 ± 82.25 (p = 0.02). To compare the factors that were determined to be statistically significant between ischemic stroke cases and controls, a multivariable logistic regression analysis was performed. The HbA1c p-value was 0.01, the odds ratio (OR) was 1.280, and the 95% CI was 1.11-1.48. The other variables apart from HbA1c that were statistically significant between the ischemic stroke cases and the controls were age (p < 0.01, OR: 1.280, 95% CI: 1.06-1.11), hypertension (p = 0.618, OR: 1.130, 95% CI: 0.70-1.83), and high-density lipoprotein (p = 0.055, OR: 0.975, 95% CI: 0.95-1.00). When other cofounders were considered, it was concluded that with a 1% increase in HbA1c, the risk of stroke increases by 28% (OR: 1.28, 95% CI: 1.11-1.48). To compare the variables that were determined to be statistically significant between the control and ischemic stroke case groups, a multivariable logistic regression was used. The area under the receiver operating characteristic curve for HbA1c was 0.773and RBS was 0.600. This study shows that higher HbA1c levels in patients increase the risk of ischemic stroke. This study brings to light the need to screen the population periodically for diabetes by routinely testing for Hba1c in those who are at high risk of diabetes. Stroke risk can be reduced with early management and intervention. This study also concludes that HbA1c is a better predictor for assessing the risk of ischemic stroke than RBS levels.
