Stroke (Cerebrovascular Accident): Epidemiological, Clinical and Evolving Aspects in the Internal Medicine Department of the Public Health Establishment 1 (EPS1) of Tivaouane

Introduction: The frequency, severity, cost of treatment, morbidity and mortality of stroke make it a real public health problem. In industrialized countries, strokes are the leading cause of physical disability in adults, the second leading cause of dementia (after Alzheimer’s disease), and the third leading cause of death (after cancer and cardiovascular disease). It’s also a major cause of depression. The objective of our study was to describe the epidemiological, clinical and evolutionary aspects of stroke in the internal medicine department of Tivaouane Hospital. Material and Method: This is a retrospective study carried out from January 1, 2015 to December 31, 2018 on the files of patients hospitalized for stroke in the medical department of the EPS1 in Tivaouane. We took into account all the patients who had a brain CT (computed tomography) scan. We collected data related to socio-demographic characteristics, history, risk factors, reasons for admission, clinical signs, paraclinical examinations, as well as evolution. Results: Out of 1999 patients, 206 files of patients with stroke were collected, i.e. a proportion of 10.3%. Our study population had a mean age of 65.53 years [16 - 97 years]. We noted a clear predominance of women (50.5%). The majority of the population came from the outskirts of Tivaouane (56.7%). Risk factors for stroke were dominated by hypertension (90.3%), dyslipidemia (19.4%), previous stroke (18.9%), and diabetes (16%). The clinical signs were dominated by a motor deficit (94.1%), speech disorders (67.4%) and consciousness disorders (47%). Ischemic strokes were predominant (65%) over hemorrhagic strokes (34.5%). The outcome was generally unfavorable with 14.6% total recovery, 58.7% recovery with sequelae and a case fatality of 26.7%. Conclusion: It emerges from this study that strokes still remain a real public health problem. Knowledge of populations of risk factors as well as their proper management is fundamental in primary prevention strategies, the only guarantee for a reduction in the still very high morbidity and mortality of this disease.

Machine learning applications in stroke medicine:advancements,challenges,and future prospectives

Stroke is a leading cause of disability and mortality worldwide,necessitating the development of advanced technologies to improve its diagnosis,treatment,and patient outcomes.In recent years,machine learning techniques have emerged as promising tools in stroke medicine,enabling efficient analysis of large-scale datasets and facilitating personalized and precision medicine approaches.This abstract provides a comprehensive overview of machine learning’s applications,challenges,and future directions in stroke medicine.Recently introduced machine learning algorithms have been extensively employed in all the fields of stroke medicine.Machine learning models have demonstrated remarkable accuracy in imaging analysis,diagnosing stroke subtypes,risk stratifications,guiding medical treatment,and predicting patient prognosis.Despite the tremendous potential of machine learning in stroke medicine,several challenges must be addressed.These include the need for standardized and interoperable data collection,robust model validation and generalization,and the ethical considerations surrounding privacy and bias.In addition,integrating machine learning models into clinical workflows and establishing regulatory frameworks are critical for ensuring their widespread adoption and impact in routine stroke care.Machine learning promises to revolutionize stroke medicine by enabling precise diagnosis,tailored treatment selection,and improved prognostication.Continued research and collaboration among clinicians,researchers,and technologists are essential for overcoming challenges and realizing the full potential of machine learning in stroke care,ultimately leading to enhanced patient outcomes and quality of life.This review aims to summarize all the current implications of machine learning in stroke diagnosis,treatment,and prognostic evaluation.At the same time,another purpose of this paper is to explore all the future perspectives these techniques can provide in combating this disabling disease.

Medical Direct Cost of Hospital Admission for Cerebrovascular Accident on Medical Recovery at the Sylvanus Olympio Teaching Hospital of Lomé

Objectives: Appreciate the Medical direct cost for cerebrovascular accident on medical recovery at the Sylvanus Olympio Teaching Hospital of Lomé. Patients and method: This was a prospective and cross study that took place from 01st October 2015 to 31st July 2016 in the medical recovery Unit of Sylvanus Olympio Teaching Hospital of Lomé. Results: Of the 91 stroke patients surveyed, the average age was 55.1 years;the sex-ratio (Men/women) was 1.3 and only 8.8% of patients had benefited from INAM (National Institute of Health Insurance) granting of benefits. The proportion of ICVA was 73.6% compared to 26.4% for the MCVA. The average overall cost of granting benefits of a CVA patient was 312,245 FCFA for an average stay of 18.6 days. This cost was 399.115 FCFA in MCVA for an average stay of 19.0 days against 281.130 FCFA in ICVA for an average stay of 16.1 days. Conclusion: CVAs on the one hand inflict losses of national productivity by its handicap, and a heavy economic burden for both patients and their families on the other hand, by its high cost of granting of benefits;Hence there is the need for assistance of all kinds by national and international health actors.

Transcranial Doppler Ultrasonography to Prevent Cerebrovascular Accident in Children with Sickle-Cell Disease

Sickle-cell disease (SCD) is the most common cause of ischemic stroke in children and it happens in about 11% of patients between the age of 2 and 20 years old. About 7% of the world population is affected by hemoglobin disorders, mostly sickle cell anemia. SCD has a high prevalence in the population of African offspring and it is a public health problem in Brazil that affects more than 30,000 million people. Prevention of primary stroke might be feasible with a way to identify children at greatest risk. Transcranial Doppler Ultrasonography (TCD) to SCD patients can be a valuable service that results in a significant decrease of first stroke rates. In this work, we present a review about TCD as an effective strategy to detect children with SCD who are at risk for stroke.

Increased retinal venule diameter as a prognostic indicator for recurrent cerebrovascular events:a prospective observational study

Microvasculature of the retina is considered an alternative marker of cerebral vascular risk in healthy populations.However,the ability of retinal vasculature changes,specifically focusing on retinal vessel diameter,to predict the recurrence of cerebrovascular events in patients with ischemic stroke has not been determined comprehensively.While previous studies have shown a link between retinal vessel diameter and recurrent cerebrovascular events,they have not incorporated this information into a predictive model.Therefore,this study aimed to investigate the relationship between retinal vessel diameter and subsequent cerebrovascular events in patients with acute ischemic stroke.Additionally,we sought to establish a predictive model by combining retinal veessel diameter with traditional risk factors.We performed a prospective observational study of 141 patients with acute ischemic stroke who were admitted to the First Affiliated Hospital of Jinan University.All of these patients underwent digital retinal imaging within 72 hours of admission and were followed up for 3 years.We found that,after adjusting for related risk factors,patients with acute ischemic stroke with mean arteriolar diameter within 0.5-1.0 disc diameters of the disc margin(MAD_(0.5-1.0DD))of≥74.14μm and mean venular diameter within 0.5-1.0 disc diameters of the disc margin(MVD_(0.5-1.0DD))of≥83.91μm tended to experience recurrent cerebrovascular events.We established three multivariate Cox proportional hazard regression models:model 1 included traditional risk factors,model 2 added MAD_(0.5-1.0DD)to model 1,and model 3 added MVD0.5-1.0DD to model 1.Model 3 had the greatest potential to predict subsequent cerebrovascular events,followed by model 2,and finally model 1.These findings indicate that combining retinal venular or arteriolar diameter with traditional risk factors could improve the prediction of recurrent cerebrovascular events in patients with acute ischemic stroke,and that retinal imaging could be a useful and non-invasive method for identifying high-risk patients who require closer monitoring and more aggressive management.

Prediabetes: An overlooked risk factor for major adverse cardiac and cerebrovascular events in atrial fibrillation patients

BACKGROUND Prediabetes is a well-established risk factor for major adverse cardiac and cerebrovascular events(MACCE).However,the relationship between prediabetes and MACCE in atrial fibrillation(AF)patients has not been extensively studied.Therefore,this study aimed to establish a link between prediabetes and MACCE in AF patients.AIM To investigate a link between prediabetes and MACCE in AF patients.METHODS We used the National Inpatient Sample(2019)and relevant ICD-10 CM codes to identify hospitalizations with AF and categorized them into groups with and without prediabetes,excluding diabetics.The primary outcome was MACCE(all-cause inpatient mortality,cardiac arrest including ventricular fibrillation,and stroke)in AF-related hospitalizations.RESULTS Of the 2965875 AF-related hospitalizations for MACCE,47505(1.6%)were among patients with prediabetes.The prediabetes cohort was relatively younger(median 75 vs 78 years),and often consisted of males(56.3%vs 51.4%),blacks(9.8%vs 7.9%),Hispanics(7.3%vs 4.3%),and Asians(4.7%vs 1.6%)than the non-prediabetic cohort(P<0.001).The prediabetes group had significantly higher rates of hypertension,hyperlipidemia,smoking,obesity,drug abuse,prior myocardial infarction,peripheral vascular disease,and hyperthyroidism(all P<0.05).The prediabetes cohort was often discharged routinely(51.1%vs 41.1%),but more frequently required home health care(23.6%vs 21.0%)and had higher costs.After adjusting for baseline characteristics or comorbidities,the prediabetes cohort with AF admissions showed a higher rate and significantly higher odds of MACCE compared to the non-prediabetic cohort[18.6%vs 14.7%,odds ratio(OR)1.34,95%confidence interval 1.26-1.42,P<0.001].On subgroup analyses,males had a stronger association(aOR 1.43)compared to females(aOR 1.22),whereas on the race-wise comparison,Hispanics(aOR 1.43)and Asians(aOR 1.36)had a stronger association with MACCE with prediabetes vs whites(aOR 1.33)and blacks(aOR 1.21).CONCLUSION This population-based study found a significant association between prediabetes and MACCE in AF patients.Therefore,there is a need for further research to actively screen and manage prediabetes in AF to prevent MACCE.

RESEARCH ON SEQUELAE OF CEREBROVASCULAR ACCIDENT TREATED BY THREE DIFFERENT NEEDLING TECHNIQUES

One hundred and sixty cases of sequelae of cerebrovascular accident (CVA) wererandomly divided into three groups: The temporal point group (TG), 58 cases; the scalp acupuncturegroup(SG), 52 cases; the body acupuncture group(BG), 50 cases. It was shown that after 30 treat-ments the curative effects were significantly different (P【0. 01) among the three groups. The effectin TG was better than those in SG and BG. There was no difference in curative effects between SGand BG. It is indicated that all the three needling techniques can improve encephalic blood flow in pa-tients. It seems that the effects of the three needling techniques are as follows: TG】SG】BG.

Predictors of a Cerebrovascular Accident in a Population of Systemic Sclerosis Patients Followed at a Large Academic Center with a Dedicated Scleroderma Center

Aim: The aim of this study is to describe the clinical characteristics of patients with a diagnosis of systemic sclerosis who later suffer a stroke and to identify associations for this relationship. Background: Prior studies have showed an increased risk of cardiovascular disease among patients with chronic inflammatory disorders, with chronic inflammation leading to atherosclerosis believed to be the culprit. Systemic sclerosis (SSc) is a chronic inflammatory disease characterized by diffuse fibrosis of the skin and internal organs. Previous studies have suggested a possible link between systemic sclerosis and macrovascular complications such as stroke. Methods: This is a retrospective chart review of patients treated within the University of Pennsylvania Health System from October 2015 to April 2019 with a diagnosis of SSc. Using ICD10 codes, we identified a cohort of SSc patients who suffered a stroke. Information regarding demographics and stroke risk factors were gathered from the charts of patients with a diagnosis of both SSc plus stroke and compared to a control group of randomly selected patients with SSc who never suffered a stroke. Continuous variables were conveyed using a mean plus a standard deviation. A two-sample t-test was used to compare the two groups of patients. Qualitative variables were compared using a two-tailed Fisher’s exact test. Results: Based on a large cohort of SSc patients (n = 2080) followed between October 2015 and April 2019, we identified 36 SSc patients who developed a subsequent stroke (1.7% of cohort). When looking at risk factors for stroke in SSc patients, we identified hypertension and atrial fibrillation to be associated with the diagnosis of stroke in such patients. Specifically, 28 of the 36 patients with both SSc and stroke also had a diagnosis of hypertension while in the control group, only 17 of 36 patients had hypertension. Atrial fibrillation was seen in 9 of 36 patients with both SSc and CVA while it was seen in only 2 of 36 patients in the control group. Conclusions: This case control study demonstrated that the presence of hypertension and atrial fibrillation had a statistically significant association with the diagnosis of CVA in patients with SSc.

Acupuncture combined with Buyang Huanwu decoction in the treatment of sequelae of cerebrovascular accident:a systematic review and meta-analysis

Background:Cerebrovascular accident has high morbidity,high disability,and high mortality,possibly causing several serious sequelae and bringing a heavy burden to the patient,the family,and the society.Buyang Huanwu decoction,a classic ancient prescription of traditional Chinese medicine,and acupuncture are often used in combination to treat the sequelae of cerebrovascular accident.In the present study,we systematically evaluated the clinical efficacy and safety of acupuncture combined with Buyang Huanwu decoction in treating the sequelae of cerebrovascular accident.Methods:Relevant randomized controlled trials of acupuncture combined with Buyang Huanwu decoction in treating the sequelae of cerebrovascular accident were comprehensively retrieved from electronic databases from inception to May 8,2020,including PubMed,Embase,The Cochrane Library,China National Knowledge Infrastructure,WanFang Data,and China Science and Technology Journal Database.The main outcomes of clinical efficacy,degree of nerve function impairment,daily self-care capacity,Fugl-Meyer locomotor function score,life quality score,and occurrence of adverse reactions were subjected to meta-analysis.Results:The 28 randomized controlled trials included 2,341 patients with the sequelae of cerebrovascular accident.Systematic review and meta-analysis indicated that compared with acupuncture alone,its combined treatment with Buyang Huanwu decoction significantly increased clinical efficacy(RR=1.19,95%CI(1.14,1.23),P<0.001),improved nerve function impairment(WMD=−4.89,95%CI(−8.25,−1.53),P=0.004),promoted daily self-care capacity(WMD=15.87,95%CI(11.22,20.51),P<0.001),strengthened Fugl-Meyer locomotor function(WMD=20.89,95%CI(13.79,27.98),P<0.001),enhanced physical functioning(WMD=16.99,95%CI(6.01,27.96),P<0.001)and mental health(WMD=16.91,95%CI(9.14,24.69),P<0.001)in terms of life quality score(SF-36 scale)of patients with sequelae of cerebrovascular accident,with few adverse reactions.Conclusion:Compared with acupuncture alone,its combination with Buyang Huanwu decoction had better comprehensive effects on sequelae of cerebrovascular accident without obvious adverse reactions.

Cardiovascular and Cerebrovascular Prognosis at 5 Years of Patients Who Presented with an Ischemic Stroke at Principal Hospital of Dakar

Aims: To determine the cardiovascular and cerebrovascular prognosis at 5 years of patients who underwent an ischemic stroke in Senegal. Methods: We performed a descriptive, retrospective and exhaustive study conducted at Principal Hospital of Dakar. We included all patients hospitalized at Principal Hospital of Dakar from 2013 to 2019 for an ischemic stroke confirmed by a cerebral CT-Scanner or by magnetic resonance imaging, and who survived the acute phase. Results: Overall, one hundred and seventy-one (171) patients were gathered. Ninety-six (96) male patients account for 56.14% and seventy-five (75) female patients account for 43.86%, with a sex ratio of 1.28. Patients’mean age was 66.33 ±13.99 years. Twenty-one (21) young patients (12.35%), aged less than 50 years, presented with an ischemic stroke. Myocardial infarction was found in a female patient (0.6%) 3 months after she experienced an ischemic stroke, nine (9) patients (5.29%) underwent a recurrence of the ischemic stroke with a mean recurrence period of 8 months and extremes ranging from 1 to 24 months. Five (5) patients (2.92%) developed dementia with a score less than 28. A 30 years old patient presented with epilepsy 12 months after the ischemic stroke accounting for 0.58%. We registered ninety (90) deaths that occurred in a mean period of 24 months ± 9.8 after they presented their ischemic stroke, standing for 52.63% amongst which thirty-five (35) accounting for 39% were female patients and fifty-five patients (55) representing 61% were male patients. Mortality-related factors included: advanced age, past medical history of heart surgery, known as dyslipidemia, physical inactivity, obesity and recurrent ischemic stroke. Conclusion: Long-term prognosis of ischemic stroke remains unclear in Senegal. Therefore, a strategy for primary prevention is highly crucial and it requires the control of risk factors in general and that of high blood pressure in particular.

Traumatic Brain Injury and Cerebral Vascular Accident: Application of Rasch Analysis to Examine Differences in Disability and Outcome in Post-Hospital Rehabilitation

The purpose of this study was to demonstrate an application of Rasch analysis to identify differences in disability profiles resulting from traumatic brain injury (TBI) and cerebral vascular accident (CVA) and to examine outcome differences between the two groups following post-hospital residential rehabilitation. Participant data were collected from 32 facilities in 16 states. From 2990 neurologically impaired individuals with consecutive admissions from 2011 through 2017, 874 met inclusion criteria: TBI (n = 687) or CVA (n = 187), 18 years or older, minimum length of stay of one month, and maximum chronicity of 1 year. Participants were evaluated at admission and discharge on the Mayo Portland Adaptability Inventory-Version 4 (MPAI-4). Rasch analysis was performed to establish item reliability, construct validity and item difficulty. A Repeated Measures Multivariate Analysis of Covariance (RM MANCOVA) determined group differences and improvement from admission and discharge. Rasch Analysis demonstrated satisfactory construct validity and internal consistency (Person reliability > 0.90, Item reliability > 0.98 for admission and discharge MPAI-4s). Both groups showed significant improvement on the MPAI-4 (p 0.0005). The TBI group was more impaired on the adjustment scale at both admission and discharge (p 0.001). Rasch analysis identified two distinct impairment patterns. CVA participants exhibited deficits characteristic of focal impairment while the TBI group presented with deficits reflective of diffuse impairment. Rehabilitation was shown to be beneficial in reducing disability following neurologic injury in both groups. Importantly, Rasch Analysis accurately produced unique disability profiles that differentiated the treatment groups. This unique statistical technique offers a promising prescriptive hierarchical model for guiding neurological rehabilitation treatment.

Impact of Strokes: The Burden of Care, Post-CVA Fatigue & Caregiver Role Strain

Strokes and cerebral vascular accidents (CVAs) and related disease events are an unfortunate circumstance that inflicts individuals around the world and impacts people every day as individuals and their caregivers. The consequences of these strokes or CVA events are life-changing for all those involved. As a result of long-term disability related to strokes, the caregiver may undergo many emotional, psychological, and physical factors that impact their daily lives. There is a relatively short period of time to react to the necessary change and as a result there may be differences in coping associated with these unexpected health circumstances. Many stoke victims experience motor, cognitive, emotional, and psycho-social deficits and their caregivers may not be prepared for these abrupt life altering effects. The impact for caregivers, factors impacting strokes, and solutions for care will be addressed in the paper. Evidence suggests that post fatigue stroke (PFS) may be triggered by a dysfunction of the stress system. Family caregivers with a low level of social engagement may be more likely to perceived stress, and increased risk for caregiver role strain.

结构化认知康复治疗在新加坡脑卒中后认知功能障碍患者中的应用效果分析

目的目前关于脑卒中后认知功能障碍(post stroke cognitive impairment,PSCI)预后的研究较少,尤其是关于接受结构化认知康复治疗但预后无显著改善患者的脑血管病危险因素尚未有报道。本研究旨在探讨影响认知康复治疗应用效果的脑血管病危险因素,为临床实践提供依据。方法对149例缺血性脑卒中患者[年龄(63.60±9.66)岁,男性64.4%]进行为期8周的非药物结构化认知康复治疗,并收集纵向的预后数据。采用蒙特利尔认知评估量表(Montreal cognitive assessment,MoCA)和痴呆生活质量量表(dementia-quality of life instrument,DemQOL)在基线、治疗结束时和治疗结束后6个月进行整体认知功能和生活质量评估。最后通过回归分析评估结构化认知康复治疗对卒中后认知功能障碍预后的影响。结果卒中发作次数更多的患者在接受结构化认知康复治疗结束时MoCA评分提高不明显(OR=2.17,95%CI:0.98~4.81,P=0.056)。与基线相比,脑白质高信号程度越严重的患者在接受结构化认知康复治疗结束时MoCA评分提高越不明显(OR=2.13,95%CI:1.04~4.38,P=0.039)。存在深部微出血的患者在接受认知康复治疗后6个月MoCA评分改善不明显(OR=19.93,95%CI:1.04~384,P=0.047)。结论卒中发作次数、脑白质高信号程度和深部微出血等脑血管病危险因素影响认知康复治疗的预后。然而,这些发现仍需进一步研究验证,且可指导未来临床试验的设计。

脑卒中患病影响因素的研究现状

随着脑卒中的发病率逐年升高,给社会、家庭和患者带来了巨大的痛苦、经济压力和社会负担,因而加强其疾病因素的分类、研究和预警,对降低发病率和死亡率具有重要意义。因此,本文从不可控因素(年龄、性别、遗传、环境等)、疾病因素(高血压、糖尿病、高血脂、冠心病、偏头痛等)、个人因素(生活习惯、心理因素、睡眠因素等)、其他因素等方面对脑卒中发病的影响因素进行综述,以期为脑卒中的预防、治疗和护理提供依据。

针刺联合康复训练治疗脑卒中后偏瘫的回顾性研究

【目的】分析针刺联合康复训练治疗脑卒中后偏瘫的临床疗效。【方法】采用回顾性研究方法,选取2021年1月至2023年1月在海口市人民医院中南大学湘雅海口医院就诊的121例脑卒中后偏瘫的患者,根据是否进行针刺治疗分为对照组和针刺组,对照组59例给予常规的康复训练方法治疗,针刺组62例在常规康复治疗的基础上增加针刺治疗,疗程均为1个月。观察2组患者治疗前后的中医证候积分的变化情况,以及脑血管阻力值包括颈动脉平均血流量(Qmean)、平均血流速度(Vmean)、脑血管床特性阻抗(Zc)、血管外周阻力(R)的情况,比较2组患者治疗前后卒中影响量表(SIS)、神经功能缺损程度量表(CSS)以及Fug-Meyer运动功能量表(FMA)评分的变化情况,并评价2组患者的临床疗效。【结果】(1)针刺组总有效率为93.55%(58/62),对照组为79.66%(47/59)。针刺组疗效优于对照组,差异有统计学意义(P<0.05)。(2)治疗后,2组患者的各项中医证候积分及总积分均明显改善(P<0.05),且针刺组在改善中医证候积分方面明显优于对照组,差异有统计学意义(P<0.05)。(3)治疗后,2组患者的脑循环动力学参数均明显改善(P<0.05),且针刺组在改善脑循环动力学参数方面明显优于对照组,差异有统计学意义(P<0.05)。(4)治疗后,2组患者的SIS、CSS、FMA评分均明显改善(P<0.05),且针刺组在改善SIS、CSS、FMA评分方面明显优于对照组,差异均有统计学意义(P<0.05)。【结论】针刺治疗脑卒中后偏瘫疗效显著,其疗效优于单纯常规康复训练。

健康体检人群心脏代谢指数与脑血管功能积分值的相关性分析

目的探讨健康体检人群心脏代谢指数(CMI)与脑血管功能积分值(CVHI)的相关性。方法本研究为横断面研究,选取2023年1-7月在新疆医科大学第一附属医院健康管理中心参加健康体检的1636例体检人员为研究对象。收集一般资料,完成相关体格检查和实验室检查。根据CVHI积分值的最佳截断点(75分)分为CVHI正常组和CVHI异常组,采用Logistic回归分析探讨影响CVHI积分值的因素,受试者工作特征(ROC)曲线下面积(AUC)评估CMI对CVHI积分值的预测价值。结果在1636例体检人员中,使用脑血管功能检测仪筛检出脑卒中风险高危人群419例(25.6%)。CVHI正常组与异常组在年龄、性别、高血压、糖尿病、血脂异常、运动缺乏等方面比较,差异有统计学意义(P均<0.05)。CVHI异常组的收缩压、舒张压、体质指数、腰围、腰臀比、腰高比、总胆固醇、甘油三酯、空腹血糖、尿酸、肌酐、尿素、心脏代谢指数均高于CVHI正常组(P<0.05)。年龄、高血压、糖尿病、收缩压、尿酸、CMI是CVHI积分值的影响因素(P<0.05)。CMI预测CVHI积分值<75人群的ROC曲线下面积为0.602。CVHI积分值随着CMI水平的增高而降低(P<0.05),CMI≥0.4918的CVHI积分值异常率(31.0%)明显高于CMI<0.4918的CVHI积分值异常率(18.7%)(P<0.05)。CVHI积分值与CMI呈负相关(r=-0.143,P<0.05)。结论随着CMI的增加,CVHI积分值逐渐降低,筛选出脑卒中高危人群的风险逐步增加,这对脑卒中高危人群的筛检具有一定的参考价值。
