Manejo clínico de la apoplejía en macroadenoma hipofisario no funcionante durante el embarazo: Reporte de un caso

La apoplejía hipofisaria es un evento infrecuente, especialmente en el embarazo, con pocos casos reportados en la literatura. Se presenta secundario a infartos hemorrágicos por cambios vasculares en un tumor hipofisario. Se puede manifestar con cambios hormonales cuando es secundario a tumores funcionantes o con síntomas neurológicos cuando ejerce efecto de masa en el caso de los tumores no funcionantes. El diagnóstico es por sospecha clínica, principalmente ante síntomas que sugieren efecto masa con compromiso neurológico y visual. Estudios como pruebas de función hormonal y resonancia magnética del cerebro son herramientas para confirmar la patología. Se describe el caso de una paciente de 30 años con embarazo de 28 semanas que presentó cefalea asociado a síntomas visuales que progresaron durante la gestación, con diagnóstico de apoplejía hipofisaria se presenta el abordaje clínico y opciones de manejo que buscaron preservar la viabilidad fetal e integridad materna.  (provisto por Infomedic International)

Pituitary apoplexy is a rare event, especially in pregnancy, with few cases reported in the literature. It occurs secondary to hemorrhagic infarcts due to vascular changes in a pituitary tumor. It may manifest with hormonal changes when secondary to functioning tumors or with neurological symptoms when it exerts mass effect in the case of non-functioning tumors. The diagnosis is based on clinical suspicion, mainly in the presence of symptoms suggesting mass effect with neurological and visual involvement. Studies such as hormone function tests and brain MRI are tools to confirm the pathology. We describe the case of a 30-year-old patient with a 28-week pregnancy who presented headache associated with visual symptoms that progressed during gestation, with a diagnosis of pituitary apoplexy, the clinical approach and management options that sought to preserve fetal viability and maternal integrity are presented.

Neuroprotective Potential of a Novel Soluble Guanylate Cyclase Stimulator the Riociguat Alone or in a Combination Manner with Resveratrol in Experimental Stroke Model in Rats / Potencial Neuroprotector del Novedoso Estimulador de Guanilato Ciclasa Soluble, el Riociguat solo o en Combinación con Resveratrol en un Modelo Experimental de Ataque Cerebrovascular en Ratas

SUMMARY: In this study we aimed to examine the effect of novel vasodilatory drug Riociguat co-administration along resveratrol to recover neurodegeneration in experimental stroke injury. For that purpose, thirty-five adult female rats were divided into five groups (Control, MCAO, MCAO + R, MCAO + BAY, MCAO + C) of seven animals in each. Animals in Control group did not expose to any application during the experiment and sacrificed at the end of the study. Rats in the rest groups exposed to middle cerebral artery occlusion (MCAO) induced ischemic stroke. MCAO + R group received 30 mg/kg resveratrol, and MCAO + BAY group received 10 mg/kg Riociguat. The MCAO + C group received both drugs simultaneously. The drugs were administered just before the reperfusion, and the additional doses were administered 24h, and 48h hours of reperfusion. All animals in this study were sacrificed at the 72nd hour of experiment. Total brains were received for analysis. Results of this experiment indicated that MCAO led to severe injury in cerebral structure. Bax, IL-6 and IL-1ß tissue levels were up-regulated, but anti-apoptotic Bcl-2 immunoexpression was suppressed (p<0.05). In resveratrol and Riociguat treated animals, the neurodegenerations and apoptosis and inflammation associated protein expressions were improved compared to MCAO group, but the most success was obtained in combined treatment exposed animals in MCAO + C group. This study indicated that the novel soluble guanylate stimulator Riociguat is not only a potent neuroprotective drug in MCAO induced stroke, but also synergistic administration of Riociguat along with resveratrol have potential to increase the neuroprotective effect of resveratrol in experimental cerebral stroke exposed rats.

En este estudio, nuestro objetivo fue examinar el efecto de la coadministración del nuevo fármaco vasodilatador Riociguat junto con resveratrol para recuperar la neurodegeneración en lesiones por ataques cerebrovasculares experimentales. Para ello, se dividieron 35 ratas hembras adultas en cinco grupos (Control, MCAO, MCAO + R, MCAO + BAY, MCAO + C) de siete animales en cada uno. Los animales del grupo control no fueron sometidos a ninguna aplicación durante el experimento y se sacrificaron al final del estudio. Las ratas de los grupos expuestas a la oclusión de la arteria cerebral media (MCAO) indujeron un ataque cerebrovascular isquémico. El grupo MCAO + R recibió 30 mg/kg de resveratrol y el grupo MCAO + BAY recibió 10 mg/kg de Riociguat. El grupo MCAO + C recibió ambos fármacos simultáneamente. Los fármacos se administraron antes de la reperfusión y las dosis adicionales se administraron a las 24 y 48 horas de la reperfusión. Todos los animales en este estudio fueron sacrificados a las 72 horas del experimento. Se recibieron cerebros totales para su análisis. Los resultados indicaron que la MCAO provocaba lesiones graves en la estructura cerebral. Los niveles tisulares de Bax, IL-6 e IL- 1ß estaban regulados positivamente, pero se suprimió la inmunoexpresión antiapoptótica de Bcl-2 (p <0,05). En los animales tratados con resveratrol y Riociguat, las neurodegeneraciones y las expresiones de proteínas asociadas a la apoptosis y la inflamación mejoraron en comparación con el grupo MCAO, sin embargo el mayor éxito se obtuvo en el tratamiento combinado de animales expuestos en el grupo MCAO + C. Este estudio indicó que el nuevo estimulador de guanilato ciclasa soluble Riociguat no solo es un fármaco neuroprotector potente en el ataque cerebrovascular inducido por MCAO, sino que también la administración sinérgica de Riociguat junto con resveratrol tiene el potencial para aumentar el efecto neuroprotector del resveratrol en ratas experimentales expuestas a un ataque cerebrovascular.

Neurotrophic Factor Mediated Neurorestorative Effect of Pongamia pinnata Against Transient Cerebral Hypoperfusion and Reperfusion in Rats: Preliminary Histological and Molecular Level Evidence / Efecto Neurorestaurador Mediado por Factor Neurotrófico de Pongamia pinnata Contra la Hipoperfusión y Reperfusión Cerebral Transitoria en Ratas: Evidencia Preliminar de un Estudio a Nivel Histológico y Molecular

SUMMARY: Stroke is the leading cause of acquired physical disability in adults and second leading cause of mortality throughout the world. Treatment strategies to curb the effects of stroke would be of great benefit. Pongamia pinnata is a recent attraction in medicine, owing to its abundant medicinal benefits with minimal side effects. The present study aimed to examine acute and subacute effect of Pongamia pinnata leaf extract on transient cerebral hypoperfusion and reperfusion (tCHR) in Wistar rats. 24 adult Wistar rats (12 each for acute and subacute study) were divided in to four groups each viz normal control group, tCHR + NS group, tCHR + 200mg/kg bw and tCHR + 400mg/kg bw groups. Cerebral ischemia induction was carried out by bilateral common carotid artery occlusion and reperfusion. Ethanolic extract of Pongamia pinnata leaves were orally administered for 7 days and 21 days after the surgical procedure for acute and subacute study respectively. Behavioural analysis, histological assessment, and estimation of mRNA levels of HIF-1, GDNF, BDNF and NF-kB were performed. In both acute and subacute study, there was significant improvement in the beam walking assay, neuronal count, decreased neuronal damage in histological sections and higher mRNA expression of BDNF and GDNF in the treatment groups. There was no significant difference in the expression of HIF1 and NF-kB. Thus, Pongamia pinnata has excellent neurorestorative property reversing many of the effects of ischemic stroke induced by tCHR in rats with the underlying mechanism being an improvement in the expression of neurotrophic factors GDNF and BDNF.

El ataque cerebrovascular es la principal causa de discapacidad física adquirida en adultos y la segunda causa de mortalidad en todo el mundo. Las estrategias de tratamiento para frenar los efectos del ataque cerebrovascular serían de gran beneficio. Pongamia pinnata es una atracción reciente en la medicina, debido a sus abundantes beneficios medicinales con mínimos efectos secundarios. El presente estudio tuvo como objetivo examinar el efecto agudo y subagudo del extracto de hoja de Pongamia pinnata sobre la hipoperfusión y reperfusión cerebral transitoria (tCHR) en ratas Wistar. Se dividieron 24 ratas Wistar adultas (12 cada una para el estudio agudo y subagudo) en cuatro grupos, el grupo control normal, el grupo tCHR + NS, los grupos tCHR + 200 mg/kg de peso corporal y tCHR + 400 mg/kg de peso corporal. La inducción de la isquemia cerebral se llevó a cabo mediante oclusión y reperfusión bilateral de la arteria carótida común. El extracto etanólico de hojas de Pongamia pinnata se administró por vía oral durante 7 días y 21 días después del procedimiento quirúrgico para estudio agudo y subagudo respectivamente. Se realizaron análisis de comportamiento, evaluación histológica y estimación de los niveles de ARNm de HIF-1, GDNF, BDNF y NF-kB. Tanto en el estudio agudo como en el subagudo, hubo una mejora significativa en el ensayo de desplazamiento del haz, el recuento neuronal, una disminución del daño neuronal en las secciones histológicas y una mayor expresión de ARNm de BDNF y GDNF en los grupos con tratamiento. No hubo diferencias significativas en la expresión de HIF1 y NF-kB. Por lo tanto, Pongamia pinnata tiene una excelente propiedad neurorestauradora que revierte muchos de los efectos del ataque cerebrovascular isquémico inducido por tCHR en ratas, siendo el mecanismo subyacente una mejora en la expresión de los factores neurotróficos GDNF y BDNF.

Improving walking via real-time visual feedback after stroke in treadmill training (RE-VISIT): a protocol for randomized controlled trial / Melhorando a caminhada por meio de feedback visual em tempo real após acidente vascular cerebral em treinamento em esteira (RE-VISIT): um protocolo para ensaio clínico randomizado

BACKGROUND: After a stroke, most patients often suffer reduced walking ability and balance. Restoring walking ability and improving balance are major goals of stroke rehabilitation. Treadmills are often used in clinical setups to achieve these goals. Adding dimensions to the visual feedback in addition to the mirror for real-time frontal view is proven to enhance the gait. It is, therefore, important to design additional real-time visual feedback in treadmill training, in particular for the sagittal view involved side. OBJECTIVE: The objective of this study is to test if the real-time sagittal visual feedback during treadmill training is superior to the conventional mirror feedback treadmill training program of equivalent intensity in improving walking speed and balance after stroke. METHODS/DESIGN: The RE-VISIT trial (Real-time Visual feedback after Stroke in Treadmill training) is registered in the Clinical Trial Registry of India (CTRI/2023/10/058299). In this two-arm randomized control trial, which will be a single-blinded study, 42 eligible stroke survivors undergoing rehabilitation will be randomly allocated (1:1 ratio) to either real-time visual sagittal feedback along with front mirror (experimental) group or only front mirror treadmill training (control) group, all the participants will receive 15 sessions of treadmill training for up to 15 min at a safe self-selected speed over 5-6 weeks. The RE-VISIT (experimental) group will receive real-time, visual sagittal view feedback of the involved lower limb trajectory along with the routine front mirror view during treadmill training and will be asked to modify their gait pattern. The control group will receive treadmill walking training only with the routine front mirror view feedback. Clinical and gait assessments will be conducted at the baseline, immediately following the final session of training, and at the 9th week during follow-up. The outcome measures of interest are walking speed (primary) and balance (secondary), which will be measured prior to baseline, post 15 sessions of training, and at the 9th week following training. DISCUSSION: This REVISIT trial will provide insight and contribute to the existing innovation and modifications of incorporating realtime visual feedback during treadmill training in post-stroke gait rehabilitation. The findings will help the better designing of a gait rehabilitation program with a treadmill for post-stroke subjects to improve walking speed, and balance for those who have greater difficulties in community ambulation. We anticipate that those in the REVISIT training will demonstrate improved walking ability.

CONTEXTO: Após o acidente vascular cerebral, a maioria dos pacientes frequentemente sofre redução da capacidade de caminhar e do equilíbrio. Restaurar a capacidade de caminhar e melhorar o equilíbrio são os principais objetivos da reabilitação do AVC. As esteiras são frequentemente usadas em ambientes clínicos para atingir esses objetivos. Está comprovado que adicionar dimensões ao feedback visual, além do espelho para visão frontal em tempo real, melhora a marcha. É, portanto, importante projetar feedbacks visuais adicionais em tempo real no treinamento em esteira, em particular para o lado envolvido na visão sagital. OBJETIVO: O objetivo deste estudo é testar se o feedback visual sagital em tempo real durante o treinamento em esteira é superior ao programa de treinamento em esteira com feedback de espelho convencional de intensidade equivalente na melhoria da velocidade de caminhada e equilíbrio após acidente vascular cerebral. MÉTODOS/ DESENHO: O ensaio RE-VISIT (feedback visual em tempo real após acidente vascular cerebral no treinamento em esteira) está registrado no Registro de Ensaios Clínicos da Índia (CTRI/2023/10/058299). Neste ensaio de controle randomizado de dois braços, que será um estudo cego, 42 sobreviventes de AVC elegíveis em reabilitação serão alocados aleatoriamente (proporção de 1:1) para feedback sagital visual em tempo real junto com grupo de espelho frontal (experimental) ou apenas Grupo de treinamento em esteira com espelho frontal (controle), todos os participantes receberão 15 sessões de treinamento em esteira por até 15 minutos em uma velocidade segura e autosselecionada durante 5-6 semanas. O grupo RE-VISIT (experimental) receberá feedback visual em tempo real da visão sagital da trajetória dos membros inferiores envolvidos, juntamente com a visão rotineira do espelho frontal durante o treinamento em esteira e será solicitado a modificar seu padrão de marcha. O grupo de controle receberá treinamento de caminhada em esteira apenas com o feedback rotineiro da visão do espelho frontal. Avaliações clínicas e de marcha serão realizadas no início do estudo, imediatamente após a sessão final de treinamento e na 9ª semana durante o acompanhamento. As medidas de resultados de interesse são a velocidade de caminhada (primária) e o equilíbrio (secundário), que serão medidos antes da linha de base, após a 15ª sessão de treinamento e na 9ª semana após o treinamento. DISCUSSÃO: este ensaio REVISIT fornecerá insights e contribuirá para a inovação e modificações existentes na incorporação de feedbacks visuais em tempo real durante o treinamento em esteira na reabilitação da marcha pós-AVC. As descobertas ajudarão no melhor desenho de um programa de reabilitação da marcha com esteira para indivíduos pós-AVC para melhorar a velocidade de caminhada e o equilíbrio para aqueles que têm maiores dificuldades na deambulação comunitária. Prevemos que aqueles no treinamento REVISIT demonstrarão melhor capacidade de caminhada.

Abstract: Cerebral Vascular Accident (CVA) is characterized as a neurological deficit attributed to an acute injury of the central nervous system due to a vascular cause. It is one of the main causes of death, affecting mainly the elderly population and, given the disabilities imposed by stroke, the need for care arises, which is often carried out by the family caregiver. This study aimed to build an educational technology aimed at family caregivers of elderly post-stroke patients, dependent on basic care for activities of daily living, that is, a technology in video format, constituting the product of this research. This is a methodological study, carried out in an inpatient unit for neurological patients in a large university hospital located in the southern region of the country. The sample was made up of 14 judges specializing in neurology and/or gerontology from the national territory and 15 family caregivers of the elderly. Data collection took place from December to February 2024. The study consisted of three stages: 1) Preproduction: construction of the synopsis, argument, script and storyboard of the educational video, for this stage an integrative review was carried out, aiming at theoretical foundation for the development of the script for educational technology with subsequent validation of the video content by expert judges, through the Health Educational Content Validation Instrument (IVCES). To analyze the instrument, the Content Validity Index (CVI) was used and the value was considered acceptable when the result of the proportion of agreement between the expert judges was equal to or greater than 0.78; 2) Production: construction of the educational video and evaluation of the video by family caregivers of elderly people hospitalized in Neurology, using the Suitability Assessment of Materials (SAM) instrument, with content evaluation, literacy requirements, illustrations, layout and presentation and cultural suitability; 3) Postproduction: editing and final version of the educational video for subsequent dissemination. As a result of the research, the literature identified what guidance caregivers and/or family members of elderly people who suffered a stroke should receive regarding post-stroke care in preparation for hospital discharge. The video script was produced, which was validated by the agreement of the expert judges (IVC= 0.93). The video was composed of 51 scenes in Full HD resolution, lasting 8 minutes. There was 99% agreement among family caregivers of participating elderly people, making it appropriate and validated. After completing this stage, the application was completed to issue the Brazilian product certificate for the educational video at the National Cinema Agency, published on the YouTube digital platform. The video proved to be a tool that helped in the acquisition of fundamental knowledge on the topic, as it is a way of disseminating information in an attractive, simple, dynamic and democratic way.

BACKGROUND@#The 2017 American College of Cardiology/American Heart Association (ACC/AHA) blood pressure (BP) guideline lowered the threshold defining hypertension to 130/80 mmHg. However, how stage 1 hypertension defined using this guideline is associated with cardiovascular events in Chinese adults remains unclear. This study assessed the association between stage 1 hypertension defined by the 2017 ACC/AHA guideline and clinical outcomes in the Chinese population.@*METHODS@#Participants with stage 1 hypertension ( n = 69,509) or normal BP ( n = 34,142) were followed in this study from 2006/2007 to 2020. Stage 1 hypertension was defined as a systolic blood pressure of 130-139 mmHg or a diastolic blood pressure of 80-89 mmHg. None were taking antihypertensive medication or had a history of myocardial infarction (MI), stroke, or cancer at baseline. The primary outcome was a composite of MI, stroke, and all-cause mortality. The secondary outcomes were individual components of the primary outcome. Cox proportional hazards models were used for the analysis.@*RESULTS@#During a median follow-up of 11.09 years, we observed 10,479 events (MI, n = 995; stroke, n = 3408; all-cause mortality, n = 7094). After multivariable adjustment, the hazard ratios for stage 1 hypertension vs. normal BP were 1.20 (95% confidence interval [CI], 1.13-1.25) for primary outcome, 1.24 (95% CI, 1.05-1.46) for MI, 1.45 (95% CI, 1.33-1.59) for stroke, and 1.11 (95% CI, 1.04-1.17) for all-cause mortality. The hazard ratios for participants with stage 1 hypertension who were prescribed antihypertensive medications compared with those without antihypertensive treatment during the follow-up was 0.90 (95% CI, 0.85-0.96).@*CONCLUSIONS@#Using the new definition, Chinese adults with untreated stage 1 hypertension are at higher risk for MI, stroke, and all-cause mortality. This finding may help to validate the new BP classification system in China.

Oral anti-coagulants use in Chinese hospitalized patients with atrial fibrillation / 中华医学杂志(英文版)

BACKGROUND@#Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.@*METHODS@#Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.@*RESULTS@#A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43-0.68; P  <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P  <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04-13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65-3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38-1.53; P <0.001).@*CONCLUSIONS@#In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration:ClinicalTrials.gov, NCT02309398.

Objective To compare the immediate effects of acupuncture at the true and false acupoints of Yanglingquan on functional connectivity in sensorimotor network(SMN)and dorsal attentional network(DAN)of stroke patients based on functional magnetic resonance imaging(fMRI)technology;To explore the central regulatory mechanism and acupoint specificity of acupuncture in stroke patients with hemiplegia.Methods Totally 20 patients with stroke and hemiplegia were included in the study.fMRI scans of acupuncture at the true and false acupoints of Yanglingquan were performed once every 2 weeks,and motion-related SMN and DAN were extracted by independent component analysis to compare the differences in functional connectivity.Results In SMN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior temporal gyrus,inferior frontal gyrus,cuneiform lobe,and anterior cuneiform lobe,as well as the left middle temporal gyrus,occipital gyrus,superior temporal gyrus,parahippocampal gyrus,inferior frontal gyrus,and superior temporal gyrus.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior frontal gyrus,middle frontal gyrus,and cingulate gyrus,as well as the left medial frontal gyrus,anterior cingulate gyrus,lentiform nucleus,and caudate nucleus.In DAN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior cingulate lobe,superior temporal gyrus,middle temporal gyrus,and occipital gyrus,as well as the left cingulate gyrus,posterior cingulate gyrus,and anterior cingulate lobe.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture,and the enhanced brain areas included the right anterior cingulate gyrus,left anterior cingulate gyrus,and medial frontal gyrus.Conclusion Acupuncture at Yanglingquan can activate SMN and DAN bilateral related brain regions in patients with hemiplegia,which may promote the recovery of motor function by regulating the initiation and execution of motor activities,and has more acupoint specificity compared with false acupoint.

Ankle rehabilitation aided by a lower limb exoskeleton robot can improve walking function after a stroke / 中华物理医学与康复杂志

Objective:To observe any effect of using a lower limb exoskeleton robot during ankle rehabilitation training on the walking ability of stroke survivors.Methods:Forty-five persons with cerebral apoplexy were randomly divided into a control group, a robot group and a combination group, each of 15. In addition to routine rehabilitation training 5 days a week for 3 weeks, the robot group additionally trained for 10 minutes assisted by a lower limb exoskeleton. The combined group joined that training and additionally undertook 10 minutes of ankle rehabilitation training. Before and after the experiment all of the participants were evaluated using the Fugl-Meyer lower extremity scale (FMA-LE), the Holden functional walking scale (FAC), and for walking speed and step frequency.Results:After treatment, significant improvement was observed in the average FMA-LE score, FAC grade, walking speed and step frequency in all 3 groups. The robot group′s average FMA-LE score, walking speed and step frequency were then significantly better than those of the control group ( P<0.05). Moreover, the average FMA-LE score, step speed and step frequency of the combined group after treatment were (22.67±1.63) min, (0.65±0.05) m/s and (80.80±4.28) steps /min, respectively, significantly better than the other two groups ( P<0.05). Conclusion:Using an exoskeleton robot combined with ankle rehabilitation training can significantly improve the walking of stroke survivors.

Effects of total saponins of Trillium tschonoskii Maxim on cognitive function and neurovascular unit in 2-VO model rats / 解放军医学杂志

Objective To observe the effects of total saponins of Trillium tschonoskii Maxim(TST)on vascular cognitive impairment(VCI),neurovascular units(NVUs),and neural circuit integrity in rats.Methods Forty-eight male Sprague-Dawley(SD)rats were randomly divided into sham-operated group,model group,TST group(intragastric administration,100 mg/kg),and donepezil group(intragastric administration,0.45 mg/kg),and then subjected to ischemic stroke by 2-VO method(bilateral common carotid artery ligation)or sham surgery.After 28 days of intragastric administration,Mirros water maze test was performed to evaluate the spatial learning and memory abilities of rats in each group.HE and Nissl staining were used to observe the pathological changes of brain tissue in rats.The expression of synuclein(SYN)in rat hippocampus was observed by immunohistochemical staining.Changes in dendritic spines in rat's hippocampal neurons were observed by Golgi staining.Western blotting was used to detect the expression levels of IL-1β,IL-10,vascular endothelial growth factor A(VEGFA),postsynaptic density protein 95(PSD95),and growth associated protein 43(GAP43)in rat's hippocampus in each group.Results In Mirros water maze test,rats in model group showed significant prolonged escape latency(P＜0.05),and a significant reduction in the number of crossing platforms and the percentage of activity time in the target quadrant(P＜0.05)than those in sham-operated group;while rats in TST group and donepezil group showed significant shortened escape latency(P＜0.01),and significant increase of the number of times of crossing platforms and the percentage of activity time in the target quadrant(P＜0.05)than those in model group.Compared of sham-operated group,model group showed a decrease in the expression of SYN and the number of neurons,Nissl bodies,and dendritic spines in the CA1 region of the hippocampus(P＜0.05).Compared with model group,TST group and donepezil group showed an increase in the expression of SYN and the number of neurons,Nissl bodies,and dendritic spines in the CA1 region of the hippocampus(P＜0.05).Western blotting showed a significant increase in the expression of IL-1β and VEGF(P＜0.05),and a decrease in the expression of IL-10,PSD95,and GAP43(P＜0.01)in rat's hippocampus of model group than those in sham-operated group.Compared with model group,TST group and donepezil group showed a significant decrease in the expression of IL-1β(P＜0.05),and an increase in the expression of VEGFA,IL-10,and GAP43(P＜0.05).Conclusions TST could alleviate cognitive impairment through promoting synaptic plasticity and neurovascular unit remodeling in 2-VO model rats,suggesting its significance as a potential drug for apoplexy.

Repetitive transcranial magnetic stimulation protocols for swallowing rehabilitation in unilateral hemispheric stroke: A scoping review

Background@#Stroke is a significant health concern globally, and dysphagia has been a very common complication. Early intervention for managing dysphagia is challenging with a lack of universally accepted treatment protocols. Non-invasive repetitive transcranial magnetic stimulation (rTMS) is emerging as a treatment option for stroke dysphagia. However, there is no standardized rTMS treatment protocol for it, leading to challenges in clinical decision-making.@*Objective@#To determine available rTMS protocols for unilateral hemispheric stroke dysphagia.@*Methods@#A scoping review using PubMed, ProQuest, and EBSCOHost databases was conducted using the keywords “dysphagia,” “stroke,” “repetitive transcranial magnetic stimulation,” “conventional therapy,” and “swallowing examination.” Eligible studies published from inception to April 2020 were appraised using the Oxford Centre for Evidence-Based Medicine and analyzed qualitatively.@*Results@#Out of 42 articles, five randomized controlled trials met the eligibility criteria. A total of 108 patients with stroke and oropharyngeal dysphagia were randomized into one of the following treatment groups: (1) rTMS (unilateral or bilateral); (2) conventional dysphagia therapy (CDT); and (3) combined intervention (CI) of rTMS and CDT. The CI gave significant improvements in swallowing function and quality of life compared to CDT alone. The bilateral rTMS protocol resulted in more significant improvements than unilateral rTMS. @*Conclusion@#There are various and heterogeneous treatment protocols involving neuromodulation available for stroke dysphagia. The combination of bilateral excitatory-inhibitory rTMS and CDT seems to result in an optimal outcome for swallowing function among patients with unilateral hemispheric stroke dysphagia.

Successful Emergency Endovascular Treatment of Cavernous Internal Carotid Artery Stenosis Due to Compression by a Hemorrhagic Pituitary Tumor

Ischemic stroke associated with pituitary apoplexy is an extremely rare but devastating complication. Arterial stenosis or occlusion due to direct compression secondary to acute expansion of the hemorrhagic pituitary adenoma may induce ischemic stroke. In case of presentation of diffusion-perfusion or diffusion-clinical mismatch, urgent tumor resection to decompress the involved arteries should be performed to salvage ischemic penumbra. If emergent surgery is not possible, other therapeutic options are needed to prevent the progression of cerebral ischemia. Herein, we report the case of successful revascularization achieved in a patient with ischemic stroke who underwent balloon angioplasty and stent placement for the non-atherosclerotic steno-occlusion of intracranial internal carotid artery due to pituitary apoplexy.

Effects of roxadustat versus recombination human erythropoietin on coronary artery calcification in maintenance hemodialysis patients / 中国药房

OBJECTIVE To compare the effects of roxadustat and recombination human erythropoietin （rHuEPO） on coronary artery calcification in maintenance hemodialysis （MHD） patients. METHODS In retrospective analysis， MHD patients prescribed roxadustat in the Blood Purification Center of the First Affiliated Hospital of Chongqing Medical University from April 2019 to June 2021 were selected as the ROX group （56 patients）， and MHD patients prescribed rHuEPO during the same period were selected as the EPO group （60 patients）， and follow-up observation was conducted for 12 months. The differences in laboratory index， coronary artery calcification score （CACS）， and cardiac ultrasound parameters before and after treatment as well as the occurrence of cardiac and cerebrovascular adverse events during follow-up period were compared between the two groups. RESULTS There was no statistical difference in CACS between the two groups before and after treatment （P＞0.05）； but the difference of CACS in the ROX group was significantly lower than the EPO group （P＜0.05）. There was no statistically significant difference in cardiac ultrasound parameters and laboratory indexes between the two groups before and after treatment （P＜0.05）. The incidence of apoplexy and myocardial infarction in the ROX group was lower than that in the EPO group （P＜0.05）， and there was no statistically significant difference in the incidence of hospitalization due to heart failure between the two groups （P＞0.05）. CONCLUSIONS Compared with rHuEPO， roxadustat may have a positive effect on delaying coronary artery calcification in MHD patients and may be beneficial in reducing the incidence of myocardial infarction and apoplexy in MHD patients.

Prognostic impact of Atrial Fibrillation Pattern and other Clinical Biomarkers in patients with stroke admitted in a Tertiary Hospital in Cebu City from 2015-2022

Background@#The effect of atrial fibrillation (AF) patterns and clinical biomarkers among patients with AF-related stroke is still controversial. @*Objectives@#The objective of this study is to determine the association of the pattern of AF and markers on routine blood tests with the outcome of patients after an AF-related stroke. @*Methods@#This is a retrospective cohort study of patients with stroke and AF admitted in a tertiary hospital in Cebu City from 2015-2022. Patients’ baseline characteristics, laboratory tests, ECG, and radiologic data were collected. Descriptive statistics such as mean and frequency were computed. The Kaplan–Meier method and the log-rank test were used to calculate the incidence time. The Cox regression analysis was used to determine factors associated with survival. A stepwise regression technique was used in model building. @*Results@#The mortality rate of patients with AF-related stroke was 0.02. A Kaplan Meier survival estimate shows that patients with paroxysmal AF have better survival. Upon model building of variables, age, red cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), platelet count, low density lipid cholesterol (LDL-C), and pattern of AF were predictive of mortality in patients with AF-related stroke. @*Conclusions@#Among AF-related stroke patients admitted at a tertiary hospital in Cebu City, pattern of AF, age, RDW, NLR, platelet count, and LDL-C were associated with mortality. The parameters associated with increased mortality could be easily assessed using an ECG, CBC, and lipid profile. These are all readily available and cost-efficient.

Independência funcional, aspectos clínicos e fatores sociodemográficos em pacientes na fase aguda do Acidente Vascular Cerebral: uma análise de associação / Functional independence, clinical aspects, and sociodemographic factors in patients in the acute phase of stroke: an association analysis

RESUMO Objetivo Analisar a associação da independência funcional com aspectos clínicos de comprometimento neurológico, a localização e extensão do dano neuronal e os fatores sociodemográficos em pacientes na fase aguda do AVC. Método Estudo analítico de recorte transversal, realizado com 90 pacientes adultos e idosos acometidos por AVC isquêmico, que tiveram admissão no ambiente hospitalar nas primeiras 24 horas após o evento vascular. A coleta dos dados referentes aos aspectos clínicos e fatores sociodemográficos foi realizada pelo prontuário eletrônico e/ou entrevista para descrever o perfil dos pacientes, Oxfordshire Community Stroke Project, Alberta Stroke Programme Early CT Score, National Institute of Health Stroke Scale e a Medida de Independência Funcional. Resultados O comprometimento neurológico, de acordo com a National Institute of Health Stroke Scale, foi associado à funcionalidade nas primeiras 24 horas após o AVC. Além disso, a presença de hipertensão arterial, idade, trabalho inativo, tabagismo e extensão do dano neuronal estiveram associados à dependência funcional, mas não permaneceram no modelo final deste estudo. Conclusão A dependência funcional está associada à hipertensão arterial, idade, trabalho inativo, tabagismo, extensão do dano neuronal e grau de comprometimento neurológico nas primeiras 24 horas após o evento vascular. Além disso, um nível mais elevado de comprometimento neurológico foi independentemente associado a níveis aumentados de dependência funcional.

ABSTRACT Purpose To analyze the association of functional independence with clinical aspects of neurological impairment, the location and extent of neuronal damage and sociodemographic factors in patients in the acute phase of stroke. Methods Analytical cross-sectional study in 90 adult and older patients affected by ischemic stroke, admitted to the hospital within 24 hours of the vascular event. Sociodemographic factors and clinical aspects data were collected from electronic medical records and/or interviews in order to depict the patients'profile, Oxfordshire Community Stroke Project, Alberta Stroke Programme Early CT Score, National Institute of Health Stroke Scale, and Functional Independence Measure. Results Neurological impairment, according to the National Institute of Health Stroke Scale, was associated with functioning in the first 24 hours after the stroke. Furthermore, the presence of arterial hypertension, age, inactive work, smoking and extent of neuronal damage were associated with functional dependence, but did not remain in the final model of this study. Conclusion Functional dependence is associated with arterial hypertension, age, inactive work, smoking, extent of neuronal damage, and degree of neurological impairment in the first 24 hours after the vascular event. Furthermore, a higher level of neurological impairment was independently associated with increased levels of functional dependence.

Acidente vascular cerebral em adultos jovens no Haiti: tendência temporal da carga de doença / Stroke in young adults in Haiti: time trends in the burden of disease

As doenças crônicas não transmissíveis aumentam consideravelmente no mundo e são consideradas um enorme desafio na saúde pública. Uma dessas doenças é o Acidente Vascular Cerebral (AVC). O AVC é uma das condições que mais causam morte e consequências neurológicas e motoras no mundo, assim como no Haiti. Atualmente, representa a segunda causa de mortes e de incapacidades nesse país. Essa doença afeta mais as pessoas na terceira idade, mas, nas últimas décadas, estudos reportam que há um crescimento significativo na incidência do AVC nos adultos jovens. Contudo, não há estudos que avaliem esse desfecho na população de adultos jovens do Haiti. Nesse sentido, é importante avaliar a tendência da carga da doença nessa população e compará-la com a do Caribe, região na qual se encontra o Haiti. Nesse país, há um foco maior nas doenças transmissíveis, e, com isso, o AVC vem sendo negligenciado. Como decorrência, isso agrava a carência de especialistas nesta área de cuidado e a escassez de recursos para realizar estudos e reforçar estratégias de prevenção. Nessa pesquisa, foram utilizados os dados do Global Burden of Disease Study (GBD) para analisar a tendência da mortalidade, da incidência e dos anos de vida ajustados por incapacidade (em inglês, DALYs) por AVC, em adultos jovens (25-49 anos) no Haiti e no Caribe, entre 1990 e 2019. Foi utilizado o modelo de Regressão Prais-Winsten para classificar a tendência temporal da doença e o Annual Percent Change (APC) para comparar o Haiti com a região do Caribe, a tendência temporal foi analisada segundo sexo, faixa etária do AVC e os seus subtipos. Como resultado a tendência da incidência, mortalidade e DALYs entre os adultos jovens, de 1990 a 2019, mostrou tendência de declínio no Haiti, para ambos os sexos e em todos os tipos de AVC, e tendência de estabilidade na região do Caribe. Em conclusão, a incidência, mortalidade e DALYs por AVC parecem estar diminuindo na região do Haiti, mas as taxas desse país seguem sendo muito mais altas em comparação ao Caribe.

Chronic non-communicable diseases are on the increase worldwide and are considered a major public health challenge. One of these diseases is cerebrovascular accident (CVA). Stroke is one of the conditions that most causes death and neurological and motor consequences in the world, as well as in Haiti. It is currently the second leading cause of death and disability in Haiti. This disease mostly affects people in old age, but in recent decades, studies have reported a significant increase in the incidence of stroke in young adults. However, there are no studies evaluating this outcome in Haiti's young adult population. In this sense, it is important to assess the trend in the burden of disease in this population and compare it with that of the Caribbean, the region in which Haiti is located. In this country, there is a greater focus on communicable diseases and, as a result, stroke has been neglected. As a result, this exacerbates the shortage of specialists in this area of care and the scarcity of resources to carry out studies and strengthen prevention strategies. In this study, data from the Global Burden of Disease Study (GBD) was used to analyze the trend in mortality, incidence and disability-adjusted life years (DALYs) due to stroke in young adults (25-49 years) in Haiti and the Caribbean between 1990 and 2019. The Prais-Winsten Regression model was used to classify the temporal trend of the disease and the Annual Percent Change (APC) to compare Haiti with the Caribbean region, the temporal trend was analyzed according to sex, age group of stroke and its subtypes. As a result, the trend in incidence, mortality and DALYs among young adults, from 1990 to 2019, showed a declining trend in Haiti, for both sexes and all types of stroke, and a stable trend in the Caribbean region. In conclusion, stroke incidence, mortality and DALYs seem to be decreasing in the Haitian region, but the rates in this country remain much higher compared to the Caribbean.

Comparación entre tenecteplase y alteplase en la trombolisis intravenosa del ataque cerebrovascular isquémico / Comparison between tenecteplase and alteplase in intravenous thrombolysis for acute ischemic stroke / Comparação entre tenecteplase e alteplase na trombólise intravenosa do acidente vascular cerebral isquémico

Introducción: la trombolisis intravenosa es parte fundamental del tratamiento agudo de los pacientes que sufren un ataque cerebrovascular (ACV) isquémico. Existe un interés creciente en la utilización de tenecteplase como alternativa trombolítica a alteplase. El objetivo del presente trabajo es comparar la efectividad clínica de tenecteplase respecto a alteplase en la trombolisis intravenosa del ACV isquémico. Método: estudio de cohorte, bispectivo y unicéntrico, de todos los pacientes ingresados con ACV isquémico y que recibieron trombolíticos intravenosos, desde 2019 a 2022. Se compararon prospectivamente los pacientes tratados con tenecteplase con aquellos tratados con alteplase como control histórico. Se realizó test de chi cuadrado o exacto de Fisher para la asociación de variables categóricas y prueba de Wilcoxon para la comparación de medianas. Se consideró significativo un valor p menor de 0,05. Resultados: se incluyeron 69 pacientes (33 recibieron alteplase y 36 tenecteplase). La mediana de la escala de NIHSS fue de 11 (RIC 8-18) y del tiempo inicio de síntomas-aguja de 160 minutos (RIC 120-208). No se hallaron diferencias estadísticamente significatvas entre los puntajes de las escalas de coma de Glasgow y NIHSS al egreso hospitalario, así como en la escala de Rankin modificada (mRS) 0-2 y mortalidad a los seis meses, entre los dos grupos de pacientes. Tampoco hubo diferencias en las complicaciones hemorrágicas intracraneanas entre ambos grupos (13,9% para tenecteplase y 12,1% para alteplase). Conclusiones: se presenta el primer estudio acerca del tema en nuestro medio. En concordancia con los recientes ensayos internacionales, el presente trabajo no mostró diferencias significativas en los resultados clínicos de los pacientes tratados con tenecteplase o alteplase. El tenecteplase podría ser una alternativa razonable a alteplase como terapia trombolítica en el ACV isquémico, con una buena relación costo-beneficio y forma de implementación más sencilla. Se necesitan estudios aleatorizados y con un mayor número de pacientes.

Introduction: intravenous thrombolysis is a key part of the acute treatment of patients with ischemic stroke. There is a growing interest in the use of tenecteplase as a thrombolytic alternative to alteplase. The aim of this study is to compare the clinical effectiveness of tenecteplase versus alteplase in intravenous thrombolysis for ischemic stroke. Method: a single-center, bispective cohort study of all patients admitted with ischemic stroke who received intravenous thrombolytics from 2019 to 2022. Patients treated with tenecteplase were prospectively compared with those treated with alteplase as a historical control. Chi-square or Fisher's exact test was used for the association of categorical variables, and the Wilcoxon test was used for median comparison A p-value of less than 0.05 was considered significant. Results: a total of 69 patients were included in the study (33 received alteplase and 36 received tenecteplase). The median NIHSS scale score was 11 (IQR 8-18), and the median time from symptom onset to needle was 160 minutes (IQR 120-208). No statistically significant differences were found between Glasgow Coma Scale and NIHSS scores at hospital discharge, as well as in modified Rankin Scale (mRS) 0-2 and mortality at 6 months, between the two groups of patients. There were also no differences in intracranial hemorrhagic complications between both groups (13.9% for tenecteplase and 12.1% for alteplase). Conclusions: This is the first study on the topic in our setting. In line with recent international trials, our study did not show significant differences in clinical outcomes of patients treated with tenecteplase or alteplase. Tenecteplase could be a reasonable alternative to alteplase as thrombolytic therapy in ischemic stroke, with a good cost-benefit ratio and simpler implementation. Randomized studies with a larger number of patients are needed.

O objetivo deste estudo foi comparar a eficácia clínica da tenecteplase com a alteplase na trombólise intravenosa do AVC isquêmico. Métodos: estudo de coorte, bispectivo, em um único centro, de todos os pacientes admitidos com AVC isquêmico que receberam trombolíticos intravenosos de 2019 a 2022. Os pacientes tratados com tenecteplase foram comparados prospectivamente com aqueles tratados com alteplase como um controle histórico. O teste de qui-quadrado ou exato de Fisher foi realizado para a associação de variáveis categóricas e o teste de Wilcoxon para a comparação de medianas. Um valor de p inferior a 0,05 foi considerado significativo. Resultados: Foram incluídos 69 pacientes (33 receberam alteplase e 36 tenecteplase). A mediana do escore da escala NHISS foi de 11 (RIC 8-18) e a mediana do tempo de início dos sintomas foi de 160 minutos (RIC 120-208). Não foram encontradas diferenças estatisticamente significativas entre os escores de coma de Glasgow e NIHSS na alta hospitalar, bem como na Escala de Rankin modificada (MRS) 0-2 e na mortalidade em 6 meses, entre os dois grupos de pacientes. Também não houve diferenças nas complicações hemorrágicas intracranianas entre os dois grupos (13,9% para tenecteplase e 12,1% para alteplase). Conclusões: Este é o primeiro estudo sobre o assunto em nosso meio. De acordo com estudos internacionais recentes, nosso estudo não mostrou diferenças significativas nos resultados clínicos em pacientes tratados com tenecteplase ou alteplase. A tenecteplase poderia ser uma alternativa razoável à alteplase como terapia trombolítica no AVC isquêmico, com uma boa relação custo-benefício e implementação mais fácil. São necessários estudos randomizados com um número maior de pacientes.
