    Full Text Available Stroke is the third leading cause of death in the United States (US and a leading cause of serious, long-term disability. Incidence of ischemic stroke is higher than hemorrhagic stroke. The aim is to conduct pharmacoepidemiology study on cerebrovascular accident patient by evaluating the use and the effects of drugs, and quantification of adverse drug reactions, drug utilization studies to improve the quality and use of medicines. A prospective observational study was conducted in department of general medicine and ICU at Mallareddy hospital, data was collected from 130 patients and it was proposed to be conducted for 6 months. Among 130 patients 78(60% are males and 52(40% are females. Among all age groups major number of CVA patients was seen in 60-69 years (30%. Among them 92% of strokes are Ischemic majorly seen in both males and females and8% strokes are hemorrhagic. Ischemic stroke (94.87% is majorly seen in 60-69 yr age group. Among various risk factors Hypertension (36.43% is the major risk factor found in males (60% and females (40%.Antiplatelet drugs (25.75% are the highest number of drugs given in patients 71.27% in males and 28.72% in females. Highest numbers of drugs are given in 50-59yrs age group and are antiplatelets. As a clinical pharmacist 16 adverse drug reactions and 25 drug interactions are reported.

    Full Text Available Abstract Background Cerebrovascular complications are severe events following orthotopic liver transplantation (OLT. This study aimed to observe the clinical and neuroimaging features and possible risk factors of in-hospital cerebrovascular complications in the patients who underwent OLT. Patients and methods We retrospectively reviewed 337 consecutive patients who underwent 358 OLTs. Cerebrovascular complications were determined by clinical and neuroimaging manifestations, and the possible risk factors were analyzed in the patients with intracranial hemorrhage. Results Ten of 337 (3.0% patients developed in-hospital cerebrovascular complications (8 cases experienced intracranial hemorrhage and 2 cases had cerebral infarction, and 6 of them died. The clinical presentations were similar to common stroke, but with rapid deterioration at early stage. The hematomas on brain CT scan were massive, irregular, multifocal and diffuse, and most of them were located at brain lobes and might enlarge or rebleed. Infarcts presented lacunar and multifocal lesions in basal gangliar but with possible hemorrhagic transformation. The patients with intracranial hemorrhage had older age and a more frequency of systemic infection than non-intracranial hemorrhage patients. (P = 0.011 and 0.029, respectively. Conclusion Posttransplant cerebrovascular complications have severe impact on outcome of the patients who received OLT. Older age and systemic infection may be the possible risk factors of in-hospital intracranial hemorrhage following OLT.

El universo de estudio fue de 96 pacientes con diagnóstico clínico y electrocardiográfico de infarto agudo de miocardio con supradesnivel del segmento ST.Resultados: Existió predominio del sexo masculino (61,4 %, el grupo etario más afectado fue entre 65 y 74 años (39,6 %. La hipertensión arterial constituyó el principal factor de riesgo encontrado (71,9 %. En el 60,2 % de los pacientes que recibieron tratamiento trombolítico, el tiempo puerta-aguja fue entre los 30 y 60 minutos, y la mayoría de los casos [34 (35,4 %] arribaron al hospital entre las 3 y 6 horas del inicio de los síntomas. El alivio del dolor y el regreso del ST se presentaron en el 100 % de las trombólisis efectivas. La causa más frecuente de no trombólisis fue la evolución del episodio isquémico mayor a 12 horas, y falleció un 33,3 % de los pacientes que no recibieron tratamiento trombolítico.Conclusiones: Predominaron el sexo masculino, las edades entre 65 y 74 años, y la hipertensión arterial. La mayoría recibió trombólisis, con tiempo dolor-puerta entre 3 y 6 horas, y puerta-aguja entre 30 y 60 minutos. La complicación que más se presentó durante la trombólisis fue la hipotensión arterial y la causa más frecuente de no realización del procedimiento fue el tiempo dolor-puerta mayor a 12 horas, donde predominaron los fallecimientos. La trombólisis oportuna sigue siendo la principal herramienta para elevar la supervivencia de los pacientes con infarto agudo de miocardio en hospitales sin intervencionismo coronario percutáneo.

    Full Text Available RESUMEN En el corazón de Granada, la nueva Escuela de Arquitectura se instala sobre las preexistencias del antiguo Hospital Militar, situado en el barrio del Realejo. El edificio que se adecua a espacio docente suma así un nuevo eslabón en la cadena de transformaciones que, desde preexistencias del periodo nazarí, han ido conformando mediante adiciones, transformaciones y cambios de uso, un conjunto arquitectónico que es reinterpretado por el proyecto y la posterior ejecución de la obra. En su actuación y aprovechando el desnivel topográfico, la sección arquitectónica toma el mando a la hora de dotar al conjunto de una idea integradora: a través de ella se produce la localización de los programas para conseguir una lectura de las diversas escalas del edificio, atenta especialmente a los patios, claustros, galerías y zaguanes y a sus concatenaciones, así como a la captación de la luz a través de diversos recursos cenitales. El proceso constructivo descubre la estructura de muros y el artesonado de los techos, recuperándose desde clave contemporánea, aquellos que resultan ser preexistencias ejemplares. Ambos recursos –luz cenital y espacios abiertos– se reúnen en la adición subterránea del Aula Magna, en el que la evocación a la excavación arqueológica y el silencio de la concentración cohabitan con el bullicio estudiantil del patio liberado sobre él. SUMMARY In the heart of Granada, the new School of Architecture is housed in the old, converted, Military Hospital, located in the Realejo district.

    Stroke after coronary by-pass grafting (CABG) is often disabling. The incidence of ischemic stroke may approach 3% to 5%. Several risk factors have been identified including previous history of stroke, prolonged cardiopulmonary bypass time, and postoperative atrial fibrillation. Objective was to determine the incidence and risk factors of neurological deficit after open heart surgery. Retrospective study was done during the period 1992-1995 at the King Khalid University Hospital, Riyadh, Saudi Arabia. There were 350 patients who were subjected to (CABG), 10 patients (2.8%) found to suffer from cerebrovascular accidents (CVA) following open-heart surgery. In 8 patients, the complaint lasted more than 24 hours (stroke), while 2 patients developed transient ischemic attacks (TIA). Five factors were found to be associated with increased risk of post cardiac surgery CVA. These factors are postoperative atrial fibrillation, carotid bruit, past history of heart failure, past history of CVA and smoking. The authors concluded that it is necessary to start a prospective study to verify the area of improvement with regards to technique, selection of patients and mode of perfusion during cardiopulmonary bypass (CPB) Arabia.

    Hypertension is the most important modifiable factor for cerebrovascular disease. Stroke and dementia are growing health problems that have considerable social and economical consequences. Hypertension causes brain lesions by several mechanisms predisposing to lacunar infarctions, leucoaraiosis, and white matter changes as well as to intracerebral haemorrhages. These parenchymal damages determine evident or silent neurological alterations that often precede the onset of cognitive decline. It is important to recognize cerebrovascular disease and, above all, to correlate typical lesions to hypertension. Antihypertensive therapy has shown clinical benefits in primary and secondary prevention of stroke. These drugs represent important instruments against cerebrovascular disease but their effects on cognition are still matter of debate. Cerebral parenchymal and functional damages have to be considered together to make medical intervention more incisive. PMID:19100549

    BACKGROUND: Cerebrovascular intervention is a medical strategy to diagnose and treat cerebrovascular disease by intravascular intervention techniques. With the continual developments of computer technology, imageology, and angiography, cerebrovascular intervention techniques have developed rapidly.OBJECTIVE: To summarize and to evaluate vascular imaging diagnostic techniques, vascular intra-arterial thrombolysis, vascular intra-arterial angioplasty, and vascular embolization in clinical applications.RETRIEVAL STRATEGY: An online search was conducted in PubMed for English language reports, published from January 2002 to January 2008, containing the key words: intervention therapy, cerebral vascular disease, endovascular intervention and angioplasty. A total of 57 publications were identified. Inclusion criteria: articles about cerebrovascular intervention for cerebrovascular disease; articles published either in high impact factor journals or in recent years. Exclusion criteria: duplicated articles.LITERATURE EVALUATION: 30 articles were identified concerning intravascular intervention techniques and arterial angioplasty. Of those, 7 articles were reviews and 23 were clinical or basic studies.DATA SYNTHESIS: Carotid artery and basilar artery stenosis were important etiological factors for ischemic cerebrovascular disease. The mechanism of stenosis induction included atherosclerotic plaque exfoliation and stenosis could cause hemodynamic changes to induce cerebral infarction. Therefore, the treatment of carotid artery and basilar artery stenosis played a key role in preventing ischemic cerebral infarction. The international organization for subarachnoid hemorrhage aneurysm has conclusively shown that both relative and absolute risk factors of intravascular embolotherapy were reduced compared to those of surgical occlusion, demonstrating the important role of vascular embolization for the treatment of intracranial aneurysm. Endovascular stents were placed into the

    Neurological complications in orthotopic heart transplantation represent a major cause of morbidity and mortality despite successful transplantation. The most frequent perioperative neurological complications are delirium or encephalopathy. In this period cerebrovascular complication ranges between 5-11%. After the perioperative period, the 5-year stroke risk after cardiac transplantation is 4.1%. In a retrospective study conducted with 314 patients who underwent cardiac transplantation, it was found that 20% of cerebrovascular complications occurred within the first two weeks after transplantation, while 80% occurred in the late postoperative phase. Of these, ischemic stroke is the most common subtype. In the perioperative periode, hemodynamic instability, cardiac arrest, extracorporeal circulation over 2 hours, prior history of stroke, and carotid stenosis greater than 50% have been reported to be risk factors for the occurrence of cerebrovascular complications. Perioperative cerebrovascular complications are associated with higher mortality and poor functional outcome at one year follow-up. After the perioperative period, the only factor that has been significantly associated with an increased risk of cerebrovascular complications is a history of prior stroke, either ischemic or hemorrhagic. Other associated factors include unknown atrial fibrillation, septic emboli from endocarditis, cardiac catheterization and perioperative hemodynamic shock. According to the TOAST etiologic classification, the most prevalent etiologic subtype of ischemic stroke is undetermined cause. PMID:21804780

    Full Text Available Objective: Stroke is defined as the sudden occlusion or rupture of cerebral arteries or veins resulting in focal cerebral damage and clinical neurologic deficits. The risk factors for stroke in children are numerous and differ from those in adults. Identification of these factors can prevent subsequent strokes. The aim of this study is to determine the etiology of stroke in children.Methods: In this descriptive prospective study, children who were referred to pediatric neurology clinic in Mofid Children's Hospital due to acute hemiparesis during 2 years period (Sep 2003-Sep 2005 were evaluated and their diagnosis was cerebrovascular disorders, in the view of physical examination and brain imaging.Findings: The study group consisted of 40 children in age groups between 3 months to 14 years old. The most common age group at presentation was 2 to 5 years old. Occurrence was predominant during autumn and winter (70%. The most common clinical presentations were acute hemiparesis (85% and seizures (40%. The other symptoms were as follow: 15% decreased level of consciousness, 12.5% fever, 7.5% VI nerve palsy, and 2.5% cerebellar signs. 20% of patients suffered from hemorrhagic and 80% had ischemic stroke. In 60% of the patients specific etiologic factors were identified and in the rest of the group, risk factors could be delineated. The most common etiologies were: 17.5% cardiac diseases or procedures and 10% hematologic disorders. Other etiologies included: 7.5% prothrombotic states, 7.5% CNS infection, 5% mitochondriopathy, 2.5% for each of the head trauma, migraine, serum lipid abnormality, hypertension and arteriovenus malformation. The most common risk factors consisted of 40% anemia and 20% infections.Conclusion: This study demonstrates that stroke in children is a multifactorial process. Identification of the underlying risk factors for cerebrovascular disorders is highly desirable because many of the risk factors can be prevented, resulting in

    Full Text Available Aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology.Consecutive 100 stroke patients with aphasia admitted in Valie Asr hospital, Khorasan in 2003 enrulled in this prospective study. Diagnosis of stroke and aphasia was made by a neurolosist and topography of involved cerebrovascular territories confirmed by topographic maps of brain in CT scan. Global, Broca and Wernicke subtypes of aphasia constituted 52%, 40% and 6% of the cases respectively. Based on the usual nourishment of Broca and Wernicke areas by anterior and posterior cortical branches of the middle cerebral artery, 79% of Global, 47% of Broca and 50% of Wernicke aphasias had a compatible infarct topography. Other cases had no congruent infarct topography with involved linguistic area of their brain. Specific cerebrovascular topography for subtypes of aphasia in stroke patients was not found. The effects of cerebrovascular lesions on linguistic functions are not predictable by their topography in CT scan.

    The glycocalyx is a gel-like layer lining the luminal surface of the endothelium. The glycocalyx exerts an important barrier role because it prevents exposure of plasma components to the endothelial surface. Disruption of the glycocalyx by local inflammation or ischemia results in decreased glycocalyx thickness which is associated with a number of vascular diseases. The cerebrovascular glycocalyx has sparsely been studied, but is of great interest because of its potential role in cerebrovascular disease. In this review, we describe all existing techniques to visualize the glycocalyx and designate techniques that may be suitable for studying the cerebrovascular glycocalyx. A total of seven imaging techniques are discussed thoroughly, including transmission electron microscopy, intravital microscopy, micro-particle image velocimetry, confocal laser scanning microscopy, two-photon laser scanning microscopy, orthogonal polarization spectral imaging and sidestream dark field/oblique imaging. Measurement of serum concentrations of glycocalyx-specific constituents is another method for glycocalyx analysis. Also, we have reviewed the methods of glycocalyx analysis by using these imaging techniques. So far, the cerebrovascular glycocalyx has only been studied in vitro. However, other cerebral microcirculatory properties have been studied in vivo. This suggests that the cerebrovascular glycocalyx can be studied in vivo by using some of the described techniques, when specific software is subjoined to the analysis. In conclusion, we have summarized techniques available for glycocalyx assessment, and explained the significance and technical possibilities regarding cerebrovascular glycocalyx visualization. Cerebrovascular glycocalyx assessment would add valuable information to our understanding of the pathophysiology of cerebrovascular disease. Moreover, as a part of the blood-brain barrier, more knowledge on the cerebrovascular glycocalyx may lead to better understanding of

Del centenar largo de españoles que ocuparon una o varias veces la cartera de la guerra desde la convocatoria de Cortes en 1.809 hasta nuestra Guerra Civil, raro fue el que no llevaba en sus bolsillos al incorporarse a su puesto un proyecto de reforma militar y lo mismo podría decirse de los que en número sensiblemente igual se sucedieron en el Ministerio de Marina, todos los cuales eran portadores de su personal programa naval. Del mismo modo también puede afirmarse que en casi todas las situaciones en que, con éxito o sin él, se produjo un cambio sustancial en el funcionamiento de las Instituciones, los que lo protagonizaron o eran militares o buscaron y encontraron apoyo en las Fuerzas Armadas.

    Full Text Available La mortalidad global por accidente cerebrovascular (ACV ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%. Se registraron 38 muertes intrahospitalarias (17 ACV isquémicos y 21 ACV hemorrágicos, representando una mortalidad global del 2.5% (1.7% en ACV isquémicos y 4.8% en ACV hemorrágicos. No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

  12. A five-year study of particulate matter (PM2.5) and cerebrovascular diseases

    International Nuclear Information System (INIS)

    Cerebrovascular accidents, or strokes, are the second leading cause of mortality and the leading cause of morbidity in both Chile and the rest of the world. However, the relationship between particulate matter pollution and strokes is not well characterized. The association between fine particle concentration and stroke admissions was studied. Data on hospital admissions due to cerebrovascular accidents were collected from the Ministry of Health. Air quality and meteorological data were taken from the Air Quality database of the Santiago Metropolitan Area. Santiago reported 33,624 stroke admissions between January 1, 2002 and December 30, 2006. PM2.5 concentration was markedly seasonal, increasing during the winter. This study found an association between PM2.5 exposure and hospital admissions for stroke; for every PM2.5 concentration increase of 10 μg m−3, the risk of emergency hospital admissions for cerebrovascular causes increased by 1.29% (95% CI 0.552%–2.03%). Highlights: •Particulate matter pollution – cerebrovascular diseases relationship is not well known. •Cerebrovascular diseases are the second leading cause of mortality and the leading cause of morbidity. •PM2.5 increase 10 μg/m3 the risk of hospital admissions for stroke causes increases by 1.29%. •The results are similar to that of other cities worldwide. -- Relationship between PM pollution and strokes is not well characterized. In Santiago the risk of the stroke increased by 1.29%; for every increase of 10 μg m−3 in PM2.5

  17. Cognitive impairments in cerebrovascular disease

    Full Text Available Cerebrovascular diseases belong to a group of the major causes of cognitive impairments, in the elderly in particular. The paper presents current ideas on the etiology and pathogenesis of vascular cognitive impairments (VCI. The etiological factors of VCI may be divided into genetic, sociodemographic, and common risk factors for vascular and other diseases. The pathogenesis of VCI is multifactorial; cognitive function decrement results from brain damage due to cerebral circulatory disorders. Damage to the deep white matter portions and basal ganglions plays a leading role in the development of cognitive deficit in cerebral circulatory insufficiency, disrupting the connections between the frontal lobes and subcortical structures (a dissociation phenomenon. Regulatory functions are impaired; instability of volitional attention develops; the speed of thinking processes and the performance of professional and everyday skills are suffered, mnestic functions being impaired to a lesser extent. Impairments in other higher cortical functions, such as speech, gnosis, praxis, thinking, generally occur in the later stages of cognitive deficit. The comprehensive approach to examining patients with cognitive dysfunctions, which encompasses physical examination with a mandatory evaluation of neurological symptoms, neuropsychological testing, laboratory studies, instrumental diagnostic methods, and structural and functional neuroimaging techniques, are most justified now. VCI therapy is a challenging task requiring the specific features of different types of cognitive deficit to be analyzed, by providing a rationale for the choice of medications. Therapeutic effectiveness may be enhanced by rational combined multimodal therapy, by keeping in mind a variety of factors for the pathogenesis of VCI.

  19. Migraine, cerebrovascular disease and the metabolic syndrome

    2012-01-01

    Full Text Available Evidence is emerging that migraine is not solely a headache disorder. Observations that ischemic stroke could occur in the setting of a migraine attack, and that migraine headaches could be precipitated by cerebral ischemia, initially highlighted a possibly association between migraine and cerebrovascular disease. More recently, large population-based studies that have demonstrated that migraineurs are at increased risk of stroke outside the setting of a migraine attack have prompted the concept that migraine and cerebrovascular disease are comorbid conditions. Explanations for this association are numerous and widely debated, particularly as the comorbid association does not appear to be confined to the cerebral circulation as cardiovascular and peripheral vascular disease also appear to be comorbid with migraine. A growing body of evidence has also suggested that migraineurs are more likely to be obese, hypertensive, hyperlipidemic and have impaired insulin sensitivity, all features of the metabolic syndrome. The comorbid association between migraine and cerebrovascular disease may consequently be explained by migraineurs having the metabolic syndrome and consequently being at increased risk of cerebrovascular disease. This review will summarise the salient evidence suggesting a comorbid association between migraine, cerebrovascular disease and the metabolic syndrome.

    Full Text Available Though previously stroke was considered an old man disease, it is increasing among the young and middle aged people are not likely to die of stroke as they are of heart attack, but they are likely to be disabled for rest of their lives. As the cases of stroke admitted to medical wards, formed nearly 1/10th to 1/8th of total bed strength at any time, and their prolonged stay at hospital attracted our attention. To study the etiological factors for the present study we have thoroughly evaluated 50 pts, with acute cerebrovascular disease and focused more attention in the revaluation of physiological variants of clinical importance by examining the blood for complete blood picture, which may help a long way in near future to predict the risk group in developing an acute cerebrovascular stroke and to avoid risk factors and to take measures to rectify the variations so as to minimize the mortality due to stroke.

    2011-10-01

    A cerebrovascular accident or stroke is a sudden-onset cerebral deficit of vascular origin lasting more than 24 hours. These events represent the second leading cause of death in the world and take a particularly heavy toll in third world countries. The purpose of this study was to describe cerebrovascular lesions (type, location, size) as well as patient age and gender in Cameroon. Brain CT-scan and MRI findings from 50 stroke patients admitted to two health centers in Douala were reviewed. Data showed that 74% of patients were over 50 years of age, the 51-60 year group being the most affected. Patients were male in 64% of cases. Ischemic stroke accounted for 60% of cases versus 40% for hemorrhagic stroke. The most affected sites were the sylvian territory site in ischemic stroke and the temporal lobe in hemorrhagic stroke, acconting for 43.3% and 35% of cases respectively. The median size of ischemic and hemorrhagic lesions were 2.81 cm3, and 26.98 cm3 respectively. Hemorrhagic stroke and lacunar infarcts were more common in this sample. Discrepancies between results at the two hospitals may be due to the use of different imaging techniques. Indeed, MRI is known to be more sensitive than CT-scan for acute detection of stroke lesions.

    Full Text Available Military Orders had slave manpower in their lands since their foundation. However, the hospitals for ransoming captives owned by the Order of Santiago are the best example of how slavery worked in the kingdom of Leon-Castile during the twelfth and thirteenth centuries. These houses had enough room to provide lodging for captives while ransoms were being negotiated. They also helped to redistribute those Muslims who, lacking this possibility, became slaves of the order itself, or were sold in the slave markets of the kingdom. The scarce records kept in the Archivo Histórico Nacional, section Órdenes Militares, referring to slaves, help to understand the development of traffic, work and manumission of these people.

    Las órdenes militares dispusieron desde su fundación de mano de obra esclava en sus tierras, pero la institución que mejor sirve para estudiar la esclavitud en los siglos XII y XIII en los reinos de León y Castilla son los hospitales para la redención de cautivos de la Orden de Santiago. Estas instituciones disponían de espacio para alojar a los cautivos mientras se negociaban rescates con los poderes islámicos, y atendían a la redistribución de aquellos musulmanes que, por no haber sido redimidos, pasaban a ser esclavos de la propia orden o a ser vendidos en los mercados de los reinos cristianos. Los escasos documentos de la sección de Órdenes Militares del Archivo Histórico Nacional dedicados a esclavos ayudan a comprender el funcionamiento del tráfico, trabajo y liberación de este colectivo.

    BACKGROUND: Carotid artery is the main source for craniocerebral blood supply. Its intimal plaque formation and arterial stenosis degree both are the risk factors for ischemic cerebrovascular disease.Therefore, the close relationship of carotid atherosclerotic plaque and ischemic cerebrovascular disease, and ultrasound evaluation of carotid atherosclerotic plaque have become the hot spot in studying ischemic cerebrovascular disease.OBJECTIVE: This study was to detect the degree of carotid atherosclerosis of ischemic cerebrovascular disease patients by ultrasonography, and to analyze the situation of carotid atherosclerosis and its relationship with clinic.DESIGN: Clinical randomized concurrent control experiment.SETTING: Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA.PARTICIPANTS: Totally 60 outpatients and inpatients with ischemic cerebrovascular disease, 42 males and 18 females, admitted to Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA between January 2006 and December 2006 were involved in the patient group. They met the diagnosis criteria of ischemic cerebrovascular disease constituted by the 4th Cerebrovascular Disease Conference in 1996, and were confirmed to suffer from ischemic cerebrovascular disease by skull CT and MRI. Another 20 subjects who received healthy examination concurrently in the same hospital, 12 males and 8 females, were involved in the control group. Informed consents of detected items were obtained from involved subjects.METHODS: The plaque thickness of mid portion, distal end and crotch of common carotid artery (CCA),internal carotid artery (ICA), external carotid artery (ECA) and vertebral artery (VA) of involved subjects,who received health examination was separately detected with color Doppler ultrasonograph (HDI-5000).Then, total integral of plaque was calculated.

  16. Elevated cardiac troponin I predicts cardiovascular or cerebrovascular events in hypertensive patients

    International Nuclear Information System (INIS)

    Objective: Whether elevated cTnI is associated with cardiovascular or cerebrovascular events in patients with hypertension (HT) without left ventricular(LV) systolic dysfunction is not clear. Method: We measured cTnI serum level in 170 patients with essential HT without LV systolic dysfunction (LVEF 55%),renal failure,and prior cardiovascular or cerebrovascular diseases. Besides, control group of 40 normal presons was established and following up (45±38)months. Results: Level of cTnI was elevated (≥0.04 ng/ml) in 15 (8.8%) of the 170 patients and in 0 (0%) of the 40 normal controls. The rate of diabetes mellitus(DM), the cardiothoracic ratio, serum NT-proBNP value, and LV mass index were significantly higher in patients with than without elevated cTnI (DM, 9/15 versus 25/155, P2, P=0.0001). Kaplan-Meier analysis demonstrated that significantly fewer (P<0.000001) patients with, than without elevated cTnI remained free of events (hospitalization due to cardiovascular or cerebrovascular disease). Stepwise Cox multivariate analysis revealed that elevated cTnT (hazard ratio, 6.59, P=0.000001) and smoking (hazard ratio, 2.26, P=0.04) were independent predictors of events. Conclusion: The present findings indicate that cTnI is a biomarker and useful predictor of future cardiovascular or cerebrovascular events in hypertensive patients. (authors)

    2003-01-01

    Summary: In order to investigate the association of fibrin monomer polymerization function (FMPF)with traditional cerebrovascular risk factors and ischemic cerebrovascular disease in old people, 1 : 1paired case-control comparative study was performed for FMPF and traditional cerebrovascular riskfactors on 110 cases of old ischemic cerebrovascular disease and 110 controls matched on age, sex andliving condition. The results showed that cerebrovascular risk factors were more prevalent in casegroup than in control group. In the case group, FMPF was significantly higher than in controlgroup. There was a significant positive correlation between hypertension and fibrin monomer poly-merization velocity (FMPV), hypertension and fibrinogen (Fbg), alcohol consumption and Fbg, butno significant correlation between diabetic mellitus, smoking and FMPF was found. Among the pa-rameters of blood lipids, there were significant positive correlations between total cholesterol (TC)and parameters of FMPF to varying degrees, triglycerides (TG) and FMPV, TG and Fbg. Our re-sults also showed there were significant linear trends between TC and FMPV (P<0. 001), TC andFbg (P=0. 0087), TG and FMPV/Amax (maximum absorbance)(P=0. 0143) respectively. Multi-ple logistic regression analysis revealed that FMPF in case group remained significantly higher thancontrol group after adjustment of all risk factors that were significant in univariate analysis. It wasconcluded that there is a possible pathophysiological link between FMPF and cerebrovascular risk fac-tors. An elevated FMPF is associated with ischemic cerebrovascular disease and an independent riskfactor of this disease. In old people, detection of FMPF might be a useful screening to identify indi-viduals at increased cerebrothrombotic risk.

    Prevention of perioperative cerebrovascular injury in patients undergoing open heart surgery is a serious task for the surgeon, especially as age and severity of atherosclerotic disease increases. The most significant predisposing factors have been identified as existing carotid arterial disease or prior stroke, heavy calcification of the aorta, renal dysfunction, advanced age, and diabetes mellitus. We have studied a series of 600 open heart patients from 1992 to 1995 from the incidence of peri-operative stroke and mortality, evaluating 16 risk factors: heavy calcification of the ascending aorta, asymptomatic carotid disease, insulin-dependent diabetes mellitus, prior CVA, left ventricular function (ejection fraction of 20% or less), age greater than 70, renal dysfunction, transmural myocardial infarction, fluid balance index greater than 2500 ccs, smoking, type of procedure, emergency procedure, non-insulin-dependent diabetes mellitus, cardiopulmonary bypass time, gender, and hypertension Stroke occurred in 8 patients (1.3%), one of whom die postoperatively. Full or near-full recovery was experienced by 5 patients; 2 patients remained partially dysfunctional at the end of the study period. The operative mortality was 2.0% (12 patients); 10 deaths occurred in hospital and 2 following discharge within 30 days postoperatively. The risk of stroke was 15 times greater in patients over age 70; 16 times greater in older males (> or = 70 years); 5 times greater in patients with prior stroke or existing (asymptomatic) carotid artery disease; 8 times greater in patients with renal dysfunction; 4 times greater with a positive fluid balance index; and twice greater when cardiopulmonary bypass exceeded 110 minutes. Four of the stroke patients had diabetes mellitus. Two of 9 patients with heavy calcification of the aortic arch suffered cerebrovascular injury. Six or more of the risk factors studied were present in 81 patients; all 8 stroke patients (9.9%) came from this

    Abstract Pneumoconiosis is a parenchymal lung disease that develops through the inhalation of inorganic dust at work. Cerebrovascular and cardiovascular events are leading causes of mortality and adult disability worldwide. This retrospective cohort study investigated the association between pneumoconiosis, and cerebrovascular and cardiovascular events by using a nationwide population-based database in Taiwan. The data analyzed in this study was retrieved from the Taiwan National Health Insurance Research Database. We selected 6940 patients with pneumoconiosis from the database as our study cohort. Another 27,760 patients without pneumoconiosis were selected and matched with those with pneumoconiosis according to age and sex as the comparison cohort. We used univariate and multivariate Cox proportional-hazard regression analyses to determine the association between pneumoconiosis and the risk of cerebrovascular and cardiovascular events after adjusting for medical comorbidities. After adjustment for age, sex, and comorbidities, the patients with pneumoconiosis exhibited a significantly higher incidence of ischemic stroke (hazard ratio [HR] 1.14, 95% confidence interval [CI] 1.05–1.24) than did those without pneumoconiosis. The incidence of hemorrhagic stroke was higher, but not significant, in the pneumoconiosis patients (HR 1.20, 95% CI 0.99–1.46). No statistically significant differences were observed between the pneumoconiosis and nonpneumoconiosis groups in acute coronary syndrome (HR 1.10, 95% CI 0.95–1.26). The findings of this study reveal an association between pneumoconiosis and a higher risk of cerebrovascular events after adjustment for comorbidities. Healthcare providers should control the related risk factors for primary prevention of stroke in pneumoconiosis patients. PMID:26945404

    Study Objectives: We investigated the prevalence of silent cerebrovascular lesions in patients with obstructive sleep apnea (OSA) and the correlation between OSA severity and prevalence of silent cerebrovascular lesions in Japanese patients. Methods: Study subjects were 192 polysomnography (PSG)-confirmed patients who visited the sleep disorders clinic in our university hospital. None had a history of cerebrovascular disease (CVD). We performed a cross-sectional study on OSA severity and the prevalence of silent cerebrovascular lesions detected by brain MRI analysis. Results: The control (AHI < 5/h) group included 19 subjects with a mean AHI of 1.7 ± 1.6/h, the mild OSAS (AHI 5 to < 15/h) group included 25 patients with a mean AHI of 9.5 ± 3.7/h, the moderate OSAS (AHI 15 to < 30/h) group included 35 patients with a mean AHI of 22.0 ± 7.0/h while the severe OSAS (AHI ≥ 30/h) group included 113 patients with a mean AHI of 59.9 ± 20.5/h. A larger percentage of patients with severe OSAS had a higher BMI and hyperglycemia than those with mild or moderate OSAS and control subjects (p < 0.05). Silent lacunar infarction was identified in 4 (21.1%) control subjects, 3 (12.0%) patients with mild OSA, 17 (48.6%) with moderate OSA and 61 (54.0%) with severe OSA. Among control subjects and the mild, moderate, and severe OSA groups, 4 (21.1%), 5 (20.0%), 19 (54.3%) and 61(54.0%), respectively, had periventricular hyperintensity (PVH); most PVH was mild to moderate. Conclusion: Results indicate that patients with moderate to severe (AHI ≥ 15/h) OSA have a higher prevalence of silent cerebrovascular lesion than those with less severe OSA.

  14. Digital subtraction angiography in ischemic cerebrovascular accidents

    International Nuclear Information System (INIS)

    Recent advances in computer and radiological technology have permitted reassessment of intravenous angiography in the evaluation of cerebrovascular disorders. Although digital subtraction angiography is a relatively new technique, it has rapidly gained a widespread acceptance. It has extended the use of angiography to outpatients and to people in whom conventional angiography is contraindicated. This reliable, safe, and relatively noninvasive technique offers the user two benefits: real-time subtraction and enhanced image quality. The system allows angiographic evaluation of the extracranial and intracranial vessels by means of intravenous injection of contrast material. Extracranial studies clearly demonstrate stenoses and occlusions of the major cervicocephalic arteries. Intracranial studies usually detect major cerebrovascular occlusions and provide insight into the collateral flow patterns. Intravenous digital subtraction angiography permits accurate assessment of cervicocephalic vessels after surgical repair. Although intravenous digital subtraction angiography obviates the need for conventional angiography in many cases, movements from the patients, or superimposition of vascular structures can substantially degrade the quality of the images. Digital subtraction angiography with intra-arterial injection of contrast medium will be contemplated in patients with poor intravenous digital subtraction angiography studies prior to surgery

    The prevalence of dementia is increasing in our aging population at an alarming rate. Because of the heterogeneity of clinical presentation and complexity of disease neuropathology, dementia classifications remain controversial. Recently, the National Plan to address Alzheimer’s Disease prioritized Alzheimer’s disease-related dementias to include: Alzheimer’s disease, dementia with Lewy bodies, frontotemporal dementia, vascular dementia, and mixed dementias. While each of these dementing conditions has their unique pathologic signature, one common etiology shared among all these conditions is cerebrovascular dysfunction at some point during the disease process. The goal of this comprehensive review is to summarize the current findings in the field and address the important contributions of cerebrovascular, physiologic, and cellular alterations to cognitive impairment in these human dementias. Specifically, evidence will be presented in support of small-vessel disease as an underlying neuropathologic hallmark of various dementias, while controversial findings will also be highlighted. Finally, the molecular mechanisms shared among all dementia types including hypoxia, oxidative stress, mitochondrial bioenergetics, neuroinflammation, neurodegeneration, and blood–brain barrier permeability responsible for disease etiology and progression will be discussed.

    Traumatic brain injuries (TBI) often involve vascular dysfunction that leads to long-term alterations in physiological and cognitive functions of the brain. Indeed, all the cells that form blood vessels and that are involved in maintaining their proper function can be altered by TBI. This Review focuses on the different types of cerebrovascular dysfunction that occur after TBI, including cerebral blood flow alterations, autoregulation impairments, subarachnoid hemorrhage, vasospasms, blood-brain barrier disruption, and edema formation. We also discuss the mechanisms that mediate these dysfunctions, focusing on the cellular components of cerebral blood vessels (endothelial cells, smooth muscle cells, astrocytes, pericytes, perivascular nerves) and their known and potential roles in the secondary injury cascade. © 2016 Wiley Periodicals, Inc.

    International Nuclear Information System (INIS)

    Objective: To evaluate the features of the brain CT scans following cerebrovascular stenting so as to guide the anticoagulant and antiplatelet treatment after cerebrovascular stenting. Methods: Eighty-seven patients with symptomatic cerebrovascular stenosis were scanned with brain CT after cerebrovascular stenting. The therapy of intracranial cerebrovascular stenting was conducted in 71 cases, and extracranial cerebrovascular stenting in 16 cases. According to the CT findings, the patients were divided into 3 types. Type I was diagnosed as normal, type II was thought that the lesions of cerebral infarctions were enhanced, and type III was diagnosed as intracranial hemorrhage. Results: In type I (normal CT scans), there were 74 (85.1%) patients. There were 8 (9.2%) cases in type II. All the infarctions were found enhanced within 35-78 days (mean 50 days). There were 5(5.7%) cases in type III. 2 patients were diagnosed as subarachnoid hemorrhage after MCA stenting, and 2 with headache were diagnosed as subarachnoid hemorrhage and cerebral hemorrhage after MCA stenting. One died of serious subarachnoid hemorrhage. The others fully recovered and were discharged. Conclusion: It is necessary to perform the prompt brain CT scan after the placement of cerebrovascular stent. The findings of high density in the cerebral infarctions within two months indicate that it is enhanced lesions, and high density in subarachnoid space in the side of stent placement indicates subarachnoid hemorrhage.

    Objective To evaluate the impact of cerebrovascular disease mortality on life expectancy (LE) in China in 2010 compared with 2005, and to identify the high-risk population (age, sex, and region) where cerebrovascular disease mortality has had a major impact on LE. Methods LE and cause-eliminated LE were calculated by using standard life tables which used adjusted mortality data from the Death Surveillance Data Sets in 2005 and 2010 from the National Disease Surveillance System. Decomposition was used to quantitate the impact of cerebrovascular disease in different age groups. Results LE in China was 73.24 years in 2010, which was higher in women and urban residents compared with men and rural residents. The loss of LE caused by cerebrovascular disease mortality was 2.26 years, which was higher in men and rural residents compared with women and urban residents. More than 30%of the loss of LE were attributed to premature death from cerebrovascular disease in people aged Conclusion Cerebrovascular disease mortality had a major impact on LE in China, with a significant difference between urban and rural residents. LE is likely to be further increased by reducing cerebrovascular disease mortality, and special attention should be paid to reducing premature deaths in people aged<65 years.

    Full Text Available A relação entre música e política sempre esteve presente nas manifestações sonoras de nosso país. As opções e acontecimentos políticos repercutem nas obras dos compositores. Estes, por sua vez, tendem a discutir e criticar esses acontecimentos, pela sátira inclusa nas marchinhas carnavalescas, por mensagens subliminares ou até mesmo de forma direta. A partir do período do Estado Novo (1937-1945, a interferência de censores torna-se clara em relação às mensagens contidas nas canções. O Departamento de Imprensa e Propaganda (DIP controla, por meio de cooptação e repressão, os ímpetos crítico musicais dos compositores. O período da ditadura militar brasileira é marcado pela censura, repressão e cerceamento à liberdade de expressão. Muitos artistas, diante das violências praticadas contra a crítica na criação artística, se mobilizam em oposição à ditadura, pela criação de canções de protesto velado, inserido nas mensagens subliminares, como na obra de Chico Buarque de Hollanda, ou de forma direta, a exemplo da canção Prá não dizer que não falei das flores, de Geraldo Vandré. Analisamos neste artigo o ambiente musical brasileiro entre 1964 e 1985, pelo viés de olhar dos compositores e da censura e as especificidades de cada movimento musical, que tecem a trama das identidades sonoras nesse momento tão rico e criativo da música popular brasileira.

    Many psychiatric syndroms in older age are based on cerebral and cerebrovascular decompensation. Diagnosis of metabolic dysfunction or vascular dysregulation--leading to cerebral decompensation--and their therapy is of greater importance than immediate therapy of psychiatric syndroms. We use Strophantin therapy, hemodilation, stabilization of blood pressure, antidiabetics combined with mild sedation by low dose neuroleptics. After achieving metabolic and cerebrovascular equilibrium we start more or less specific psychiatric syndrom therapy like antidepressants. PMID:6109459

    Full Text Available Chronic cerebrovascular attack (CCVA is a brain lesion caused by vascular factors. CCVA appears as cognitive impairments (CIs, affective (emotional disorders and focal syndromes. Treatment for CCVA requires a comprehensive approach. Effective combination therapy for CCVA involves secondary prevention of stroke and CIs; treatment of CIs; treatment of depression and other affective disorders; and neuroprotective therapy. Basic therapy for CCVA includes modification of risk factors, antihypertensive, hypolipidemic, and antithrombotic therapies. Central acetylcholinesterase inhibitors (galantamine, rivastigmine, donepezil and a reversible NMDA receptor blocker (memantine are symptomatically used at a stage of vascular and mixed dementia. There are no unique guidelines for the therapy of mild and moderate vascular nondementia-related CIs. Drug use, based on the neurochemical mechanisms underlying the development of vascular CIs, is substantiated. When choosing psychotropic agents, it is necessary to take into account the causes and clinical manifestations of neuromediator deficiency. Antidepressants are used as essential drugs. Neuroleptics and tranquilizers are additionally administered in complex-pattern syndromes, such as depression with marked anxiety. Prescription of neuroprotectors may be effective in treating both stroke and CCVA. These medicaments are most effective when a damaging factor acts, i.e. neuroprotectors should be given in a risk situation and to reduce damage. Citicoline is one of the most test drugs in a group of neuroprotectors.

    Full Text Available BACKGROUND Cerebrovascular ischemia is recognized as a major health problem, which causes significant morbidity and mortality. The main pathophysiology of ischemic stroke is atherosclerosis of cerebral vessels. Hs-CRP is a sensitive marker of inflammation tissue injury in the arterial wall, which contributes to atherosclerosis. In this study, we aim to investigate the association of hs-CRP in patients with ischemic stroke and to correlate hs-CRP levels with possible risk factors of ischemic stroke and to assess the prognostic value of hs-CRP in ischemic stroke. METHODS In the present case control study after meeting inclusion and exclusion criteria, 50 patients with acute ischemic stroke admitted in the medical ward, King George Hospital, during the period between April 2014 and October 2014 and 40 asymptomatic age and sex matched control subjects were included. RESULTS The mean hs-CRP value in cases is 3.78+5.28mg/dl and in controls is 0.425+0.305mg/dl. Mean hs-CRP value is higher (3.78mg/dl in cases when compared to controls (0.425mg/dl, which is statistically significant. P admitted with severe degree of weakness (0-1/5 power with mean hs-CRP value of 4.28+4.07 without significant improvement in the power at the time of discharge; 8(16%> with mean hs-CRP value of 10.43+7.74 were expired.

    Alterations to cerebral blood flow (CBF) have been implicated in diverse neurological conditions, including mild traumatic brain injury, microgravity induced intracranial pressure (ICP) increases, mild cognitive impairment, and Alzheimer's disease. Near infrared spectroscopy (NIRS)-measured regional cerebral tissue oxygen saturation (rSO2) provides an estimate of oxygenation of the interrogated cerebral volume that is useful in identifying trends and changes in oxygen supply to cerebral tissue and has been used to monitor cerebrovascular function during surgery and ventilation. In this study, CO2-inhalation-based hypercapnic breathing challenges were used as a tool to simulate CBF dysregulation, and NIRS was used to monitor the CBF autoregulatory response. A breathing circuit for the selective administration of CO2-compressed air mixtures was designed and used to assess CBF regulatory responses to hypercapnia in 26 healthy young adults using non-invasive methods and real-time sensors. After a 5 or 10 minute baseline period, 1 to 3 hypercapnic challenges of 5 or 10 minutes duration were delivered to each subject while rSO2, partial pressure of end tidal CO2 (PETCO2), and vital signs were continuously monitored. Change in rSO2 measurements from pre- to intrachallenge (ΔrSO2) detected periods of hypercapnic challenges. Subjects were grouped into three exercise factor levels (hr/wk), 1: 0, 2:>0 and 10. Exercise factor level 3 subjects showed significantly greater ΔrSO2 responses to CO2 challenges than level 2 and 1 subjects. No significant difference in ΔPETCO2 existed between these factor levels. Establishing baseline values of rSO2 in clinical practice may be useful in early detection of CBF changes.

  13. Lesions of nucleus tractus solitarii globally impair cerebrovascular autoregulation

    International Nuclear Information System (INIS)

    The authors studied the effects of acute bilateral electrolytic lesions of the nucleus tractus solitarii (NTS) on regional cerebral blood flow (rCBF) and its autoregulation in rats anesthetized, paralyzed, and artificially ventilated. rCBF or regional cerebral glucose utilization (rCGU) was measured 30 min after NTS lesions, by the 14C-iodoantipyrine technique or 2-deoxyglucose method, respectively. Cerebrovascular autoregulation was assessed in groups of 4-5 rats at three levels of arterial pressure (AP):90, 125, and 140 mmHg. AP was lowered by hemorrhage or elevated by intravenous infusion of phenylephrine. NTS lesions did not alter rCBF at 125 mmHg but resulted in loss of autoregulation. In contrast, lesions of the cuneate nucleus or transection of the baroreceptor afferents did not alter autoregulation. NTS lesions did not affect the reactivity of the cerebrovascular bed to hypercarbia or hypocarbia nor the rCGU in any brain regions. They conclude that lesions of the NTS impair cerebrovascular autoregulation. The effect is not due to changes in metabolism, nonspecific effects of the lesions, vasoparalysis, or interruption of the baroreceptor reflex arch. Neural pathways originating in or passing through the NTS can regulate the cerebrovascular autoregulation of the entire brain

    2016-05-01

    Down syndrome (DS) is a common cause of intellectual disability and is also associated with early age of onset of Alzheimer's disease (AD). Due to an extra copy of chromosome 21, most adults over 40years old with DS have beta-amyloid plaques as a result of overexpression of the amyloid precursor protein. Cerebrovascular pathology may also be a significant contributor to neuropathology observed in the brains of adults with DS. This review describes the features of cardiovascular dysfunction and cerebrovascular pathology in DS that may be modifiable risk factors and thus targets for interventions. We will describe cerebrovascular pathology, the role of co-morbidities, imaging studies indicating vascular pathology and the possible consequences. It is clear that our understanding of aging and AD in people with DS will benefit from further studies to determine the role that cerebrovascular dysfunction contributes to cognitive health.

  18. Depression as the cause and consequence of cerebrovascular diseases

    Directory of Open Access Journals (Sweden)

    Rabi-Žikić Tamara

    2007-01-01

    Full Text Available Inbtroduction: Recent epidemiological, clinical, neuroimaging and neuropathological studies have reported substantial evidence on the complex interactive relationships between depression and cerebrovascular diseases, especially in older populations, and plausible explanations of the etiopathogenetic mechanisms in both directions have been proposed. Poststroke depression Although there is no general consensus regarding its prevalence, it is widely accepted that major depression after stroke is common and that it should be recognized as a key factor in rehabilitation and outcome following stroke. Vascular depression The "vascular depression" hypothesis presupposes that late-onset depression may often result from vascular damage to frontal-subcortical circuits implicated in mood regulation. This concept has stimulated many researches and the obtained results support the proposed hypothesis. Depression as a stroke risk factor Recent large studies have emphasized the role of depression per se in the development of subsequent stroke. Mechanisms proposed to explain the increased risk of cerebrovascular diseases in depressed patients There are a number of plausible mechanisms that could explain why depression may increase the risk of subsequent cerebrovascular disease, the most important being sympathoadrenal hyperactivity, platelet activation, an increase in inflammatory cytokines and an increased risk of arrhythmias. Conclusion: Thorough clinical examinations determining the conventional stroke risk factors in the population with depression, as well as management of depression as part of the overall measures for the reduction of cerebrovascular risk factors are of utmost importance.

    Abstract The aim of this study is to explore whether there is a relationship between chronic pancreatitis and cerebrovascular disease in Taiwan. Using the claims data of the Taiwan National Health Insurance Program, we identified 16,672 subjects aged 20 to 84 years with a new diagnosis of chronic pancreatitis from 2000 to 2010 as the chronic pancreatitis group. We randomly selected 65,877 subjects aged 20 to 84 years without chronic pancreatitis as the nonchronic pancreatitis group. Both groups were matched by sex, age, comorbidities, and the index year of diagnosing chronic pancreatitis. The incidence of cerebrovascular disease at the end of 2011 was measured. The multivariable Cox proportional hazards regression model was used to measure the hazard ratio (HR) and 95% confidence interval (CI) for cerebrovascular disease risk associated with chronic pancreatitis and other comorbidities. The overall incidence of cerebrovascular disease was 1.24-fold greater in the chronic pancreatitis group than that in the nonchronic pancreatitis group (14.2 vs. 11.5 per 1000 person-years, 95% CI = 1.19–1.30). After controlling for confounding factors, the adjusted HR of cerebrovascular disease was 1.27 (95% CI = 1.19–1.36) for the chronic pancreatitis group as compared with the nonchronic pancreatitis group. Woman (adjusted HR = 1.41, 95% CI = 1.31–1.51), age (every 1 year, HR = 1.04, 95% CI = 1.04–1.05), atrial fibrillation (adjusted HR = 1.23, 95% CI = 1.02–1.48), chronic kidney disease (adjusted HR = 1.48, 95% CI = 1.31–1.67), chronic obstructive pulmonary disease (adjusted HR = 1.27, 95% CI = 1.16–1.40), diabetes mellitus (adjusted HR = 1.82, 95% CI = 1.72–1.92), hypertension (adjusted HR = 1.66, 95% CI = 1.56–1.76), and peripheral atherosclerosis (adjusted HR = 1.26, 95% CI = 1.06–1.51) were other factors significantly associated with cerebrovascular disease.

    International Nuclear Information System (INIS)

    To explore the role of and report congenital and genetic cerebrovascular anomalies as risk factors for stroke in a prospective and retrospective cohort of Saudi children. Children with stroke were evaluated at the Division of Pediatric Neurology (Dpn), or were seen as inpatients in the Pediatric Wards at King Khalid University Hospital (KKUH), Riyadh, Kingdom of Saudi Arabia during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Stroke work-up for each suspected case included hemostatic assays, serological, biochemical and neurophysiological tests. Neuroimaging modalities included routine skill x-rays, CT, MRI, magnetic resonance angiography (MRA) and conventional cerebral angiography. Of 104 children with stroke, congenital and genetic cerebrovascular anomalies were the underlying risk factor in 7 (6.7%). The patients were evaluated at the DPN at a mean age of 66 months (range = 8 months to 11 years, median = 6 years); and they had stroke at a mean age of 48 months (range = 2 months to 10 years, median = 8 months). Four patients had stroke in association with neurocutaneous syndromes. Two had Sturge-Weber syndrome (SWS), one had Klippel-Trenaunay syndrome associated with SWS, and the fourth had neurofibromatosis type 1. Two patients had intracranial hemorrhage secondary to ruptured aneurysm. A girl (aged 9 years and 4 months) had left posterior cerebral artery aneurysm. She was diagnosed to have autosomal dominant polycystic kidney disease following renal ultrasonography. She died 5 months later despite surgical intervention (clipping of aneurysm). The second child was an 8-months-old boy who presented with subarachnoid and intraventricular hemorrhage (IVH) following ruptured anterior communicating artery aneurysm. He recovered with no residual symptoms following successful clipping of the aneurysm. Arteriovenous malformation (AVM) caused IVH in a 7-year-old boy who reported to hospital 5 hours

    The cerebrovascular spasm is a common complication of subarachnoid hemorrhage. The prognosis is affected severely with regard to quality of life of patients, and earlier determination of the cerebral vasospasm becomes very important. In recent years, there have been many research results in early judgment of cerebrovascular spasm, and imaging technology research is particularly prominent in this area. This article summarizes the advantages and disadvantages and the specific roles of several common imaging technologies to determine the early stage of cerebral vasospasm. Transcranial Doppler (TCD) was the first used to examine cerebral vasospasm and mainly detected vascular hemodynamic changes of cerebrovascular spasm in patients. Digital subtraction angiography is the gold standard for diagnosis of cerebral vasospasm, but its efficacy in determining severity of cerebrovascular spasm indexing is still in dispute. It is invasive, it is difficult to repeat the examination, and it can induce complications, so its clinical application is limited. CT imaging technology is a hot topic in this area. There is an important guiding significance in early diagnosis and treatment of cerebral vasospasm in CT perfusion imaging (PCT) and CT angiography (CTA). PCT mainly performs qualitative and quantitative analysis through hemodynamic parameters such as cerebral blood flow, cerebral blood volume, and mean transit time. CTA is minimally invasive, fast, and reliable as an efficient imaging technology, and will possibly replace DSA for the assessment of vasospasm, particularly in critically ill patients with cerebral vasospasm in an urgent examination. This means it has greater value and helps to improve the prognosis of patients. MR imaging in the early stages to judge cerebral vasospasm has great value. DWI can effectively assess the cerebral vascular spasm earlier to detect trace bleeding sites and reflect the damage of cerebral vasospasm by apparent diffusion coefficient. Combined

    International Nuclear Information System (INIS)

    We report the outcomes of prophylactic cerebral reconstructive surgery aimed at reducing the incidence of perioperative cerebral infarction in patients with intracranial or extracranial occlusive cerebrovascular disease who were scheduled to undergo cardiac surgery. Before the surgery, carotid artery ultrasonography, magnetic resonance angiography (MRA) of the carotid artery, and magnetic resonance imaging (MRI) and MRA of the brain were performed on 875 patients. The high-risk group was defined as: patients with cervical carotid artery stenosis of at least 90%, those with a reduced cerebral perfusion reserve because of occlusion of the internal carotid or middle cerebral artery, and those with a reduced cerebral perfusion reserve because of major intracranial artery stenosis of at least 75%. According to the degree of cardiac reserve, patients in the high-risk group underwent carotid artery stenting (CAS), carotid endarterectomy (CEA), superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis, or percutaneous transluminal angioplasty (PTA). Of the 875 patients, 29 (3.3%) were classified in the high-risk group, and 16 underwent prophylactic revascularization and cardiac surgery. Prophylactic revascularization included CAS in 7 patients (including stenting of the intracranial internal carotid artery in 1 patient), CEA in 4, STA-MCA in 4 and PTA in 1. Cardiac surgery was performed on 870 of the 875 patients, and perioperative cerebral infarction occurred in 11 (1.3%). It is uncertain whether our treatment strategy significantly reduced the incidence of perioperative cerebral infarction because of the lack of accurate information on the number of patients with this condition before the present study. However, 73% of patients had a score of 1 or 2 on the modified Rankin Scale 1 month after the onset of cerebral infarction, suggesting that our strategy improved the outcome. (author)

  17. Influence of cerebrovascular arteriosclerosis on cerebral oxygenation during exercise

    International Nuclear Information System (INIS)

    Although it is assumed that cerebral oxygenation during exercise is influenced by both cardiopulmonary function and cerebrovascular arteriosclerosis, the latter factor has not been fully clarified. In the present study the relationship between the degree of cerebrovascular arteriosclerosis and cerebral oxygenation during exercise was investigated. A total of 109 patients (69 patients with coronary artery disease, 40 patients with hypertensive heart disease) (61.7±9.7 years) performed a symptom-limited exercise test with respiratory gas measurements (CPX). From the respiratory gas analysis, peak O2 uptake (VO2), the slope of the increase in VO2 to the increase in work rate (ΔVO2/ΔWR), and the slope of the increase in ventilation to the increase in CO2 output (VE/VCO2 slope) were calculated. Oxyhemoglobin (O2Hb) at the forehead was monitored using near-infrared spectroscopy. The brain ischemic score was counted based upon fluid-attenuated inversion recovery images of magnetic resonance imaging and expressed from 0 to 4. When compared with patients with a lower ischemic score (2Hb during exercise (-1.08±2.7 vs 0.77±4.1 μmol/L, p=0.011). Of brain ischemic score, left ventricular ejection fraction, peak VO2, ΔVO2/ΔWR, and the VE/VCO2 slope, ΔVO2/ΔWR was found to be the sole independent index determining cerebral O2Hb during exercise. The CPX parameters were also significantly related to the degree of cerebrovascular arteriosclerosis. Although cerebral oxygenation during exercise is mainly related to cardiopulmonary function, the degree of cerebrovascular arteriosclerosis partly influences cerebral oxygenation in patients with risk factors for atherosclerosis.

  18. Cerebral blood flow in sickle cell cerebrovascular disease

    International Nuclear Information System (INIS)

    Cerebral blood flow (CBF) has been studied by the xenon-133 (133Xe) inhalation method in 16 children with suspected sickle cell cerebrovascular disease. Abnormalities consisting of decreases in total, hemispheral, or regional CBF were found in 17 of 26 studies. Eleven studies performed immediately after stroke, transient ischemic attack, or depression of state of alertness showed abnormalities. In addition to confirming regional cerebrovascular insufficiency in children with stroke due to major cerebral artery occlusion, the method detected diffuse decrease in CBF in children with stupor, coma, and seizures who had normal angiographic findings. In contrast, six of seven studies obtained after exchange transfusion or during maintenance on hypertransfusion therapy showed normal findings. The difference between results in patients with acute neurologic disturbances and those receiving transfusion therapy was statistically significant (P less than .005). The data indicate that the 133Xe method reliably demonstrates cerebrovascular impairment in sickle cell disease. They also suggest that CBF changes in patients with sickle cell disease can be reversed by exchange transfusion and by hypertransfusion therapy. The 133Xe CBF method may be useful for following up children with sickle cell disease who are at high risk for recurrent stroke

    Patients with the postural orthostatic tachycardia syndrome (POTS) have symptoms of orthostatic intolerance despite having a normal orthostatic blood pressure (BP), which suggests some impairment of cerebrovascular regulation. Cerebrovascular autoregulation refers to the maintenance of normal cerebral blood flow in spite of changing BP. Mechanisms of autoregulation include myogenic, metabolic and neurogenic vasoregulation. Beat-to-beat recording of blood-flow velocity (BFV) is possible using transcranial Doppler imaging. It is possible to evaluate autoregulation by regressing deltaBFV to deltaBP during head-up tilt. A number of dynamic methods, relating deltaBFV to deltaBP during sudden induced changes in BP by occluding then releasing peripheral arterial flow or by the Valsalva maneuver. The deltaBFV to deltaBP provides an index of autoregulation. In orthostatic hypotension, the autoregulated range is typically expanded. In contrast, paradoxical vasoconstriction occurs in POTS because of an increased depth of respiration, resulting in hypocapnic cerebrovascular constriction, and impaired autoregulation.

    An estimated 3.2 million children worldwide have human immunodeficiency virus (HIV) infection. Antiretroviral therapy (ART) has resulted in prolonged survival, leading to an increase in complications previously recognized in adults. Children with HIV infection have increased risk of cerebrovascular disease from multiple aetiologies including HIV-associated vasculopathy, opportunistic vasculitis, cardioembolism or coagulopathy, all of which may be secondary to the infection. Prevalence of cerebrovascular disease in HIV-infected children is underestimated because of limited neuroimaging in low and middle income countries, silent events without overt motor manifestations, and mislabeling as HIV encephalopathy for non-motor manifestations such as behavioural and cognitive difficulties. No management guidelines for cerebrovascular disease in HIV-infected children exist but common practices target risk factors for stroke in low and middle income countries. Where capacity permits, screening for opportunistic infections, vasculitis, coagulopathy and cardioembolism is important. Optimising virological suppression, correction of anaemia, control of seizures and aspirin prophylaxis are management priorities. Neurosurgical interventions may have a role. PMID:26890389

    2012-03-01

    Violence against women (VAW) in India is commonly attributed to an overarching metacultural patriarchal framework. Focusing on this national culture of violence obscures the experiences of VAW among ethnic minority women. This article focuses on VAW in Northeast India, a region populated by large numbers of Scheduled Tribes with different cultural norms, and where society has become militarized by ongoing insurgency and counterinsurgency. Though tempting, militarization alone is not a sufficient explanation for VAW; instead, this article focuses on the interplay between nonfamilial and familial contexts in creating a "frontier culture of violence" in which VAW is experienced and contested.

    La crisis económica que afecta a Europa se está combatiendo con drásticos recortes al gasto social. Sin embargo, el gasto militar no se está reduciendo en la misma proporción en todos los países europeos (incluso sigue aumentando fuera de Europa) y persisten algunos llamamientos a incrementarlo y a considerarlo uno de los motores para salir de la crisis. Esta paradójica situación se explica a partir de determinadas concepciones de la seguridad y de la economía de la industria militar. Tras an...

  12. Association between cervical spine and skull-base fractures and blunt cerebrovascular injury

    International Nuclear Information System (INIS)

    Blunt cerebrovascular injuries (BCVI) are associated with high morbidity and mortality and can lead to neurological deficits. The established criteria for patients undergoing CT angiography (CTA) for BCVI are broad, and can expose patients to radiation unnecessarily. This study aimed to examine the prevalence of BCVI in patients on CTA and determine presentations associated with the highest rates of BCVI. With IRB approval, patients were selected for CTA screening for BCVI according to a predefined set of criteria at our hospital between 2007 and 2010. Patients were identified from our institution's trauma database. CTAs were retrospectively reviewed for BCVI including vasospasm and dissection. Electronic medical records were reviewed for clinical presentation and hospital course. Of 432 patients, vasospasm (n = 10) and/or dissection (n = 36) were found in 46 patients (10.6 %). BCVI was associated with cervical spine and/or skull-base fracture in 40/46 patients (87 %, P < 0.0001). Significant correlations were seen between dissection and fracture in 31/36 patients (86.2 %, p < 0.0001) and between BCVI and both neurological deficits and fractures (27/44, P < 0.0001). BCVI was significantly associated with cervical and/or skullbase fractures and neurological deficits with coexistent fractures. Patients with these injuries should be prioritized for rapid CTA evaluation for BCVI. (orig.)

  15. Study of GMP-140 RIA in the diagnosis and treatment of cerebrovascular diseases

    International Nuclear Information System (INIS)

    To investigate the relation between GMP-140 with the progress and mechanism of cerebrovascular diseases, the level of GMP-140 in both platelet and plasma in 76 cases of cerebrovascular disease and 35 normal controls were determined by radioimmunoassay (RIA). Results showed that the level of GMP-140 in both platelet and plasma of cerebrovascular diseases were remarkably higher than that in normal controls (P0.05). It was concluded that the progress, development, and prognosis of cerebrovascular diseases is strongly related to the platelet function and the level of GMP-140

  19. The investigation of cerebrovascular disorders with positron emission tomography

    International Nuclear Information System (INIS)

    Positron emission tomography (PET) provides a non-invasive, regional, in vivo method to measure physiological parameters including cerebral blood flow, glucose and oxygen metabolism, blood volume, and pH. Measurement of these parameters not only enables a more complete understanding of the pathophysiology of acute cerebral ischemia and infarction, but provides objective criteria with which to better manage patients. This chapter will first discuss PET methodology and tracer techniques used in the investigation of patients with cerebrovascular disease and then describe the progress that has already resulted from applying these methods. 73 refs.; 7 figs

    1982-07-01

    External detection of the annihilation radiation produced by water labeled with oxygen-15 was used to measure cerebrovascular permeability and cerebral blood flow in six rhesus monkeys. Use of oxygen-15 also permitted assessment of cerebral metabolic rate in two of the monkeys. Amitriptyline produced a dose-dependent, reversible increase in permeability at plasma drug concentrations which are therapeutic for depressed patients. At the same concentrations the drug also produced a 20 to 30 percent reduction in cerebral metabolic rate. At higher doses normal autoregulation of cerebral blood flow was suspended, but responsivity to arterial carbon dioxide was normal.

    Nonurgent commercial air travel in patients who have experienced a nonhemorrhagic cerebrovascular accident (CVA) may occur, particularly in the elderly traveling population. A recent CVA, particularly occurring during a person's travel, presents a significant challenge to the patient, companions, family, and health care team. Specific medical recommendation, based on accumulated scientific data and interpreted by medical experts, is needed so that travel health care professionals can appropriately guide the patient. Unfortunately, such recommendations are almost entirely lacking despite the relative frequency of CVA and air travel. This article reviews the existing recommendations with conclusions based on both these limited data and rationale conjecture. PMID:24787513

    2016-01-01

    Background and Objectives Cerebrovascular disease is a leading cause of mortality and morbidity in Korea. Understanding of cerebrovascular disease mortality trends is important to reduce the health burden from cerebrovascular diseases. We examined the changing pattern of mortality related to cerebrovascular disease in Korea over 30 years from 1983 to 2012. Subjects and Methods Numbers of deaths from cerebrovascular disease, hemorrhagic stroke, and cerebral infarction were obtained from the national Cause of Death Statistics. Crude and age-adjusted mortality rates were calculated for men and women for each year. Penalized B-spline methods, which reduce bias and variability in curve fitting, were used to identify the trends of 30-year mortality and identify the year of highest mortality. Results During the 30 years, cerebrovascular disease mortality has markedly declined. The age-adjusted cerebrovascular disease mortality rate has decreased by 78% in men and by 68% in women. In the case of hemorrhagic stroke, crude mortality peaked in 2001 but age-adjusted mortality peaked in 1994. Between 1994 and 2012, age-adjusted mortality from hemorrhagic stroke has decreased by 68% in men and 59% in women. In the case of cerebral infarction, crude and age-adjusted mortality rates steeply increased until 2004 and 2003, respectively, and both rates decreased rapidly thereafter. Conclusion Cerebrovascular disease mortality rate has significantly decreased over the last 30 years in Korea, but remains a health burden. The prevalence of major cardiovascular risk factors are still highly prevalent in Korea. PMID:27482259

    Previous experiments have shown that the vestibular system participates in cardiovascular control. However, the effects of vestibular activation on cerebrovascular regulation are not known. Therefore, the present experiment tested the hypothesis that specific vestibular activations may be beneficial to cerebral circulation during simulated orthostatic stress. Middle cerebral artery blood flow velocity (CBV; Doppler ultrasound) was measured to examine the effects of head-down neck flexion (HDNF) compared to head-down neck extension (HDNE) with and without lower body negative pressure (LBNP; -40 mmHg) (n=9). The change in CBV (DeltaCBV) during HDNF and HDNE were not different during baseline conditions, however, during LBNP, DeltaCBV was greater in HDNE compared to HDNF (-5.5+/-3.2 cm/s, -11+/-4.6%) vs. (-0.7+/-1.0 cm/s, -1.9+/-1.9%), respectively (PHDNF (0.26+/-0.05 mmHg/cm per s, 22+/-4.1%) (PHDNF (42+/-2 mmHg; P<0.05) during LBNP. These results suggest that the vestibular system may affect cerebrovascular tone during simulated postural stress by either constriction or dilation, depending on the vestibular stimulus.

    Full Text Available China es un actor geopolítico de talla universal. Sus dimensiones geopolíticas –físicas, económicas, humanas, sociopolíticas y militares– son abrumadoras. Pero, quizás, lo que impresiona y en cierta manera preocupa más es su impenetrabilidad. Referido al arte de la guerra se manifiesta de forma clara en utilizar la “decepción” como su principal estratagema –uno de sus principios básicos enunciados por Sun Tzu–. No se busca, por lo tanto, el enfrentamiento de las capacidades militares, sino la pugna entre las maestrías intelectuales. Así, el poder militar chino, tradicionalmente postergado por el poder imperial, no fue capaz de resistir el encuentro con el industrializado occidente que lo sojuzga durante el llamado “siglo infame de humillación”. Y no ha sido sino a través de dos de las más cruentas guerras de la historia de la humanidad y de la revolución comunista como el dragón herido ha vuelto a recuperar el control de su propio destino. A lomos de su Ejército Popular de Liberación, campesino e iletrado, vuelve a sus orígenes para consolidar esa única e imperecedera Civilización-Estado. Un ejército del pueblo y para el pueblo que, como brazo armado del Partido Comunista Chino, sólo mira hacia el interior de su gran muralla; conocedor del poder del resto de dimensiones geopolíticas; y que sólo empieza a alzar la vista y emprender el vuelo de la mano del milagro económico de las últimas décadas. Un poder militar orgulloso y capaz, que quiere protagonizar, junto con su sociedad, esta vez sí, “el sueño de China, el sueño del pueblo”, del “desarrollo pacífico”.

    2012-01-01

    This article contributes to the debate over the whether or not the mainstreaming of Corporate Social Responsibility/Codes of Conduct should be welcomed.

The article illustrates the argument through an analysis of two jurisgenerative processes (linked to regulation and to politics) triggered by Codes of Conduct in commercial military markets. It shows that the codes are creating both a hybrid regulatory (or constitutional) network...... that makes it possible to hold firms accountable and a militarization of politics. It does so by showing that the codes create first-, second- and third-order rules but also processes of misrecognition through distraction, distinction and diffusion that empower military professionals.

  8. Militarized humanitarianism meets carceral feminism: the politics of sex, rights, and freedom in contemporary antitrafficking campaigns.

    Science.gov (United States)

    Bernstein, Elizabeth

    2010-01-01

    Over the past decade, abolitionist feminist and evangelical Christian activists have directed increasing attention toward the “traffic in women” as a dangerous manifestation of global gender inequalities. Despite renowned disagreements around the politics of sex and gender, these groups have come together to advocate for harsher penalties against traffickers, prostitutes’ customers, and nations deemed to be taking insufficient steps to stem the flow of trafficked women. In this essay, I argue that what has served to unite this coalition of "strange bedfellows" is not simply an underlying commitment to conservative ideals of sexuality, as previous commentators have offered, but an equally significant commitment to carceral paradigms of justice and to militarized humanitarianism as the preeminent mode of engagement by the state. I draw upon my ongoing ethnographic research with feminist and evangelical antitrafficking movement leaders to argue that the alliance that has been so efficacious in framing contemporary antitrafficking politics is the product of two historically unique and intersecting trends: a rightward shift on the part of many mainstream feminists and other secular liberals away from a redistributive model of justice and toward a politics of incarceration, coincident with a leftward sweep on the part of many younger evangelicals toward a globally oriented social justice theology. In the final section of this essay, I consider the resilience of these trends given a newly installed and more progressive Obama administration, positing that they are likely to continue even as the terrain of militarized humanitarian action shifts in accordance with new sets of geopolitical interests.

    Clinical and experimental evidence point to a possible role of cerebrovascular dysfunction in Alzheimer's disease (AD). The 5xFAD mouse model of AD expresses human amyloid precursor protein and presenilin genes with mutations found in AD patients. It remains unknown whether amyloid deposition driven by these mutations is associated with cerebrovascular changes. 5xFAD and wild type mice (2 to 12months old; M2 to M12) were used. Thinned skull in vivo 2-photon microscopy was used to determine Aβ accumulation on leptomeningeal or superficial cortical vessels over time. Parenchymal microvascular damage was assessed using FITC-microangiography. Collagen-IV and CD31 were used to stain basal lamina and endothelial cells. Methoxy-XO4, Thioflavin-S or 6E10 were used to visualize Aβ accumulation in living mice or in fixed brain tissues. Positioning of reactive IBA1 microglia and GFAP astrocytes at the vasculature was rendered using confocal microscopy. Platelet-derived growth factor receptor beta (PDGFRβ) staining was used to visualize perivascular pericytes. In vivo 2-photon microscopy revealed Methoxy-XO4(+) amyloid perivascular deposits on leptomeningeal and penetrating cortical vessels in 5xFAD mice, typical of cerebral amyloid angiopathy (CAA). Amyloid deposits were visible in vivo at M3 and aggravated over time. Progressive microvascular damage was concomitant to parenchymal Aβ plaque accumulation in 5xFAD mice. Microvascular inflammation in 5xFAD mice presented with sporadic FITC-albumin leakages at M4 becoming more prevalent at M9 and M12. 3D colocalization showed inflammatory IBA1(+) microglia proximal to microvascular FITC-albumin leaks. The number of perivascular PDGFRβ(+) pericytes was significantly decreased at M4 in the fronto-parietal cortices, with a trend decrease observed in the other structures. At M9-M12, PDGFRβ(+) pericytes displayed hypertrophic perivascular ramifications contiguous to reactive microglia. Cerebral amyloid angiopathy and

  11. Contributing Mechanisms of Aortic Atheroma in Ischemic Cerebrovascular Disease.

    Kong, Qi; Ma, Xin

    2015-12-01

    In recent years, the correlation between aortic atheroma (AA) and the occurrence and recurrence of ischemic cerebrovascular disease (ICVD) has attracted much attention, but the contributory mechanisms remain controversial. This review analyzes related research on the roles of AA in ICVD, and demonstrates the correlation between the formation and development of AA and abnormal metabolism, inflammation, hemodynamic changes, and other contributory factors. The presence of complex aortic plaque (CAP) in the ascending aorta and aortic arch increases the risk of cerebral embolism and degree of injury, while the association between CAP in the descending aorta and cerebral embolism remains ambiguous. AA also functions as an indicator of atherosclerosis burden as well as hypercoagulability, which may further increase the risk of ICVD. Further study on the relationship of AA to ICVD will improve diagnosis and treatment in clinical practice. PMID:26522269

    The development of atherosclerosis is strongly associated with an increased risk for cerebrovascular accidents (CVA), including stroke and transient ischemic attacks (TIA). Certain unique occupational exposures that individuals in the NASA astronaut corps face, specifically high-performance aircraft training, SCUBA training, and spaceflight, are hypothesized to cause changes to the cardiovascular system. These changes, which include (but are not limited to) oxidative damage as a result of radiation exposure and circadian rhythm disturbance, increased arterial stiffness, and increased carotid-intima-media thickness (CIMT), may contribute to the development of atherosclerosis and subsequent CVA. The purpose of this study was to review cases of CVA in the NASA astronaut corps and describe the comorbidities and occupational exposures associated with CVA.

  13. CT findings of cerebrovascular diseases in patients with atrial fibrillation

    International Nuclear Information System (INIS)

    CT findings of cerebrovascular diseases were studied in 111 patients with atrial fibrillation (Af). One of these patients had cerebral hemorrhage, and another, subarachnoid hemorrhage, while the others all had cerebral infarctions. CT revealed 122 lesions with a low-density area (LDA) in 105 patients. Based on the cerebral artery territory, the 122 CT lesions were classified into the following 8 types: 10 hemispheric, 43 superficial, 23 deep, 28 superficial+deep, 1 anterior cerebral artery, 6 posterior cerebral artery, 10 watershed, and 1 vertebrobasilar. Therefore, infarctions of the internal carotid artery (ICA) system, including 94 infarctions of the middle cerebral artery territory, were most frequent, accounting for 94% of all lesions. The ratio of the left to the right infarctions of the ICA system was 1.1:1. However, it should be noted that non-embolic infarctions can occur even patients with Af. (author)

    Mercury (Hg) has many harmful vascular effects by increasing oxidative stress, inflammation and vascular/endothelial dysfunction, all of which may contribute to cerebrovascular diseases development. We aimed to explore the effects of chronic low-mercury concentration on vascular function in cerebral arteries and the mechanisms involved. Basilar arteries from control (vehicle-saline solution, im) and mercury chloride (HgCl2)-treated rats for 30 days (first dose 4.6μg/kg, subsequent dose 0.07μg/kg/day, im, to cover daily loss) were used. Vascular reactivity, protein expression, nitric oxide (NO) levels and superoxide anion (O2(-)) production were analyzed. HgCl2 exposure increased serotonin contraction and reduced the endothelium-dependent vasodilatation to bradykinin. After NO synthase inhibition, serotonin responses were enhanced more in control than in mercury-treated rats while bradykinin-induced relaxation was abolished. NO levels were greater in control than Hg-treated rats. Tiron and indomethacin reduced vasoconstriction and increased the bradykinin-induced relaxation only in HgCl2-treated rats. Vascular O2(-) production was greater in mercury-treated when compared to control rats. Protein expressions of endothelial NO synthase, copper/zinc (Cu/Zn), Manganese (Mn) and extracellular-superoxide dismutases were similar in cerebral arteries from both groups. Results suggest that Hg treatment increases cerebrovascular reactivity by reducing endothelial negative modulation and NO bioavailability; this effect seems to be dependent on increased reactive oxygen species and prostanoids generation. These findings show, for the first time, that brain vasculature are also affected by chronic mercury exposure and offer further evidence that even at small concentration, HgCl2 is hazardous and might be an environmental risk factor accounting for cerebral vasospasm development.

  15. Aspirin in Cardiovascular and Cerebrovascular Events: Does Market Failure Matter?

    2010-01-01

    Full Text Available Problem statement: Against the backdrop of the 2009 scientific studies qualifying the cardiovascular and cerebrovascular benefits of aspirin, two interrelated questions are raised for investigation in this study. First, why may the government intervene in an otherwise private transaction between physician and patient and between drug manufacturer and buyer, when it involves contentious pharmacological information? Second, does government intervention make a difference in what these transacting parties would otherwise have chosen to do in its absence? Approach: An Internet literature search was performed, using query term combinations, to identify relevant aspirin studies. The search yielded 61 juried publications that met our predetermined criteria for inclusion and thematic analysis. Results: Variance exists within the mix of economic and non-economic literature on aspirin information regulation. The study identified 4 instances of market failure that offer some of the most compelling theoretical and practical considerations for public policy intervention in the context of the 2009 findings. However, there is also indication that the sense of increased protection arising from safety regulations could stimulate risky behavior that nullifies their net protective effects or benefits. Conclusion: It is not clear either from the surveyed literature or existing economic theory if, ceteris paribus, regulated information alters or modifies the marginal propensity of a physician to recommend, and a patient to consume, aspirin to prevent cardiovascular and cerebrovascular events, particularly heart attacks, strokes and vascular death. The study suggests the need for policy reinforcements to safety information, if market failures are to be efficiently addressed and risk compensating behavior reduced.

    Object On July 1, 2003, the Accreditation Council for Graduate Medical Education (ACGME) implemented duty-hour restrictions for resident physicians due to concerns for patient and resident safety. Though duty-hour restrictions have increased resident quality of life, studies have shown mixed results with respect to patient outcomes. In this study, the authors have evaluated the effect of duty-hour restrictions on morbidity, mortality, length of stay, and charges in patients who underwent brain tumor and cerebrovascular procedures. Methods The Nationwide Inpatient Sample was used to evaluate the effect of duty-hour restrictions on complications, mortality, length of stay, and charges by comparing the pre-reform (2000–2002) and post-reform (2005–2008) periods. Outcomes were compared between nonteaching and teaching hospitals using a difference-in-differences (DID) method. Results A total of 90,648 patients were included in the analysis. The overall complication rate was 11.7%, with the rates not significantly differing between the pre –and post–duty hour eras (p = 0.26). Examination of hospital teaching status revealed that complication rates decreased in nonteaching hospitals (12.1% vs 10.4%, p = 0.0004) and remained stable in teaching institutions (11.8% vs 11.9%, p = 0.73) in the post-reform era. Multivariate analysis demonstrated a significantly higher complication risk in teaching institutions (OR 1.33 [95% CI 1.11–1.59], p = 0.0022), with no significant change in nonteaching hospitals (OR 1.11 [95% CI 0.91–1.37], p = 0.31). A DID analysis to compare the magnitude in change between teaching and nonteaching institutions revealed that teaching hospitals had a significantly greater increase in complications during the post-reform era than nonteaching hospitals (p = 0.040). The overall mortality rate was 3.0%, with a significant decrease occurring in the post-reform era in both nonteaching (5.0% vs 3.2%, p < 0.0001) and teaching (3.2% vs 2.3%, p < 0

  10. Persistent primitive trigeminal artery associated with cerebrovascular diseases and other cerebrosis

    International Nuclear Information System (INIS)

    Persistent primitive trigeminal artery (PPTA) is the most common permanent abnormal vascular anastomosis between carotid artery and basilar artery. PPTA is a rare cerebrovascular variation and is often associated with cerebrovascular disease (CVD). Clinically, PPTA manifests itself in symptoms such as trigeminal neuralgia, oculomotor paralysis, abducens nerve paralysis, subarachnoid hemorrhage, etc. This paper aims to review 116 PPTA cases with CVD and other cerebrosis, which have ever been reported since 1983 in English or Chinese medical literature.

    HIV-associated neurocognitive disorder remains prevalent in HIV-infected individuals despite effective antire-troviral therapy. As these individuals age, comorbid cerebro-vascular disease will likely impact cognitive function. Effective tools to study this impact are needed. This study used diffusion tensor imaging (DTI) to characterize brain microstructural changes in HIV-infected individuals with and without cerebrovascular risk factors. Diffusion-weighted MRIs were obtained in 22 HIV-infec...

  20. Crossed cerebellar atrophy in cases with cerebrovascular disease

    International Nuclear Information System (INIS)

    Crossed cerebellar atrophy (CCA) was investigated by X-ray CT to establish the incidence, mechanism, and the relation to cerebral lesions in 130 cases of unilateral supratentorial cerebrovascular diseases. The 130 cases consisted of 83 males and 47 females with cerebral infarction (65 cases) and cerebral hemorrhage (65 cases). The patients' average age was 57.6 years. Crossed cerebellar atrophy was demonstrated in 8 cases (6.2%), 6 of whom had massive cerebral infarction in the middle cerebral artery area (9.2% of the 65 cases of cerebral infarction. The six cases of CCA caused by cerebral infarction had lesions in the frontal and temporal lobes. Two had a cerebral hemorrhage in the putamen and in the thalamus, respectively, accounting for 3.1% of the 65 cases of cerebral hemorrhage. Of the 2 cases, one had putaminal hemorrhage, and the other had thalamic hemorrhage. Cerebrovascular stroke had occured in these patients with CCA more than 2 months previously. In 5 of the 8 cases of CCA, atrophy was present in the basis pedunculi and the basis pontis on the side of the cerebral lesion. However, neither dilation nor deformity of the fourth ventricle was present in any of the patients, suggesting that none of the CCA patients had atrophy of the dentate nucleus. The CCA patients had massive cerebral lesion in the frontal and temporal lobes or atrophy of the basis pedunculi and basis pontis, suggesting the presence of the transsynaptic degeneration of the cortico-ponto-cerebellar pathway. In the case of the thalamic hemorrhage, who had not hemorrhagic lesion in the frontal and temporal lobes, atrophy of the basis peduncli and basis pontis was not observed. Though dilation or deformity of the fourth ventricle is not observed in this case, presence of the degeneration of the dentate-rubro-thalamic pathway cannot be denied. CCA seems to be caused by both the transsynaptic degeneration of the cortico-ponto-cerebellar pathway and the dentate-rubro-thalamic pathway. (J.P.N.)

  1. Dipyridamole cerebral flow stress test evaluating ischemic cerebrovascular diseases

    International Nuclear Information System (INIS)

    To detect the clinical value of dipyridamole cerebral blood flow stress test in cerebrovascular diseases (CVD). Nineteen patients (9 male, 10 female, mean age=65) who were diagnosed as CVD were included. One suffered from infarct, two suffered from thrombosis, one feel dizziness. All 4 performed rest and stress test. The other 15 were VBI, 9 of them performed stress test. Rest and stress test were done two-day method using Elscint Apex SP-6 SPECT equipped with low energy all purpose collimator. Rest perfusion imaging was started 30 min after injecting 1.11 GBq 99mTc-ECD. Dipyridamole stress test was done within one week. 0.56 mg/Kg dipyridamole was injected intravenously during 4 min the same dose of ECD was injected 2 min later. The acquisition started 30 min later with the same parameter. Heart rate, ECG and the patient's complaint were monitored 2 min before and after dipyridamole. After correction for attenuation, transverse, coronal and sagittal slices were reconstructed. Eighteen ROIs were drawn symmetrically on cingulate, frontal, temporal-parietal, temporal, occipital, vision cortex, basal ganglia, superior frontal and parietal on the 3rd, 6th, 9th transverse slices, selecting the contralateral as the reference region. The counts per pixel in each ROI were divided by the counts of the mirror region to obtain the relative uptake ratio. We think it abnormality when the ratio is above 1,1 or below 0.9. The sensitivity for rest and stress rCBF test was compared. rCBF was decreased at 10 of 19 patients (sensitivity 52.6%). 14 had low rCBF after dipyridamole (sensitivity 72.3%), Among the patients who studied stress test, 6 had normal rCBF at rest and low rCBF after stress. The abnormal area was enlarged after dipyridamole for 1 patients, 2 improved and 2 unchanged. 8 of 15 VBI had normal rCBF at rest (sensitivity 53.3%). 9 of 15 VBI performed stress test. rCBF was normal at rest for 5 patients, rCBF was decreased after stress, it was improved for one

    Full Text Available Background: cerebrovascular disease and ischemic cardiopathy can be considered as an epidemic and constitute the first cause of incapacities in developed countries. Multiple studies have shown the association between uric acid levels and cerebrovascular diseases. Objective: To correlate the levels of serum uric acid and incapacities in the acute phase of cerebrovascular disease. Methods: A correlational study was carried out with 217 patients with acute cerebrovascular disease. The patient’s incapacity level was measured by using the Barthel Index and those results were related with the serum uric acid levels and other variables. Results: Male patients have higher levels of uric acid (p=0, 04; r=0, 13. Age and Barthel index were p < 0,001; r = -0, 30 and uric acid levels and Barthel Index were p=0, 03; r=-0, 14. The principal predicting factors of incapacity in the acute phase of cerebrovascular disease were the high levels of uric acid, age and diabetes mellitus. Conclusions: It is shown that the highest is the level of uric acid at advanced age; the greatest is the risk of suffering from incapacity in acute phases of cerebrovascular diseases.

  3. Clinical usefulness of creatine Kinase BB determination by a Ria method in serum of patients with cerebrovascular accidents

    International Nuclear Information System (INIS)

    The measurement of creatine kinase BB isoenzyme (CK-BB) using RIA methods could have diagnostic utility as a biological marker of cerebral damage. The aim of the present study is to evaluate whether frequent sampling (4 samples/day for 3 days) permits a better correlation between serum CKBB values and the clinical outcomes of patients with cerebrovascular accidents. 16 in-patients (12 men and 4 women) with stroke (15 of an ischemic nature and 1 hemorrhagic) have benn studied. The presence of stroke was confirmed by clinical symptoms and by CAT results. Blood samples were drawn at 6 and 12 a.m. and at 6 and 12 p.m. over 3 consecutive days after hospitalization. Values of serum CK-BB above the normal range (>7 ng/ml) were found in the 5 of the 16 (31.3%) patients studied. The mean CK-BB value observed in the patients' group was significantly higher than that found in a group of 112 control subjects (controls, mean+-SD=2.1+-1.7 ng/ml vs patients 3.3+-3.4 ng/ml, unpaired t-test p<0.025). We observed a very wide range of serum CKBB levels in most of the patients studied. Some prominent peaks of CK-BB concetrations were found in patients' outcame (Spearman correlation coefficient r-s=0.618, p<0,01). Although our results indicate that the measurement of CK-BB concentrations cannot be considered a sensitive marker of stroke, the significant correlation between serum CK-BB values and outcome suggests that high CK-BB levels could be a sign of worse prognosis in patients with cerebrovascular accidents

    Full Text Available Oil was discovered in large quantities in Nigeria in 1956 and exploration began in the same year. Before oil, agriculture and fishing had assured the Niger Delta people of a bright future. Since 1956, oil has been extracted from the Niger Delta with destructive consequences on the environment, bringing about environmental degradation and destruction of the people’s primary means of livelihood. Land and water were badly polluted, and the health of the people affected because of leaks from oil pipelines, gas flaring and acid rains. Several petitions and non-violent protests by Delta communities, women and youth against environmental destruction failed to receive attention. Rather, opposition to peaceful protests earned the people military invasions of their communities, clampdowns and jailings. The rise of militarism and terrorism in the Niger Delta was the result of the Federal Government and Oil Companies’ clampdown on non-violent protests for environmental justice in the Niger Delta. This paper discusses the history of oil exploration in the Niger Delta, oil laws, effects of oil exploration in the region, and the rise of militants and terrorists in the area. The paper uses the term, ‘environmental Justice’ to denote unfair treatment and destruction of the Delta environment resulting from oil exploration, non implementation and enforcement of environmental laws and regulations, and abuse of human rights.The paper suggests solutions for peace in the Niger Delta.

    Full Text Available Cerebrovascular accident (CA is a nowadays widely spread, highly incapacitating and often lethal event that poses a prominent clini- cal problem. Cardiovascular disease (CVD and type 2 diabetes mellitus (T2DM – an “epidemic” of the century, – are known to be its primary risk factors. Hyperglycemia promotes CA risks by induction of protein glycosylation, elevation of blood plasma atherogenic potential, activation of coagulation system with higher risk for thrombosis and disturbance of microcirculation on tissue and organ lev- els. Influence of hyperglycemia on severity and extent of neurologic damage is still under evaluation. Development of macroangiopathy is thought to be associated with media calcification, distal polyneuropathy and renal disorders, all of which are cardiovascular risk factors. Application of so-called metabolic drugs resulted in certain disillusionment, as these agents failed to prove their efficacy during clinical trials. Incidence of pulmonary edema in patients with ischemic CA and T2DM is important as it dictates the necessity for use of loop diuretics. Incidence and severity of heart failure and its correlation with degree of glycemic disorders, incidence of pulmonary em- bolism, as well as tactics of management and prognosis in patients with ischemic CA and T2DM, remains a relevant research problem.

    INTRODUCTION. Bronchopneumonia is a frequent complication in the first days after a cerebrovascular disease and is linked with a higher rate of mortality. It occurs in patients with an altered level of consciousness or tussigenic reflex, and could be prevented with an early dysphagia rehabilitation programme. AIMS. To review the scientific literature on the treatment and rehabilitation of patients with dysphagia after suffering a stroke, published between 2002 and 2012. DEVELOPMENT. A search conducted in the PubMed, Cochrane, PEDro, CINAHL and ENFISPO databases yielded 15 papers that fulfilled eligibility criteria and the initial aims of the study, providing information about 3,212 patients. The different protocols and techniques for re-education in dysphagia are described and include compensatory strategies, orofacial regulation therapy, music therapy, sensory stimulation, lip muscle, tongue, pharynx, larynx and respiratory tract training, Mendelsohn manoeuvre, neuromuscular electrical stimulation, repetitive transcranial magnetic stimulation and acupuncture. CONCLUSIONS. The studies examined in this research claim that the treatment of dysphagia following a stroke can improve the function of deglutition (coordination, speed, volume), quality of life and people's social relationships. Further work needs to be carried out to establish or define what kind of therapies, techniques, exercises or manoeuvres are the most effective in dysphagia. Generally agreed treatment or rehabilitation protocols also need to be drawn up within units that address stroke in an integrated manner. PMID:24610693

  12. Magnetization transfer MR of cerebrovascular disorders using calculated images

    International Nuclear Information System (INIS)

    This study applied a magnetization transfer contrast method to patients with cerebrovascular disorders. A 1.5 T superconducting MR unit was used, and magnetization transfer ratio (MTR) images were calculated by evaluating two paired images before and after off-resonance gradient echo pulse sequences. The normal white matter showed the highest MTRs, CSF the lowest, and gray matter, intermediate. Cerebral ischemic patients showed two patterns according to the chronological stage of the affected area. Lesions in the acute and subacute stages revealed higher transfer rates than those in the chronic stage. Patients with cerebral hemorrhage were divided into three groups: the hyperacute group showed a low transfer pattern; the acute group presented inhomogeneous high transfer rates; and the subacute group showed remarkably low transfer rates. In the acute and subacute ischemic stages, increased macromolecules caused higher MTRs than in the chronic stage. In hemorrhagic groups, low MTRs in subacute hemorrhage reflected the transfer of methemoglobin. High MTRs in acute hemorrhage with rich deoxyhemoglobin suggested increased fibrin, plasma, and serum components of macromolecules. The MTC method provided new chronological information on cerebral hemorrhage, adding to that provided by routine MR images. (author)

  13. The anatomy and pathophysiology of extracranial atherosclerotic cerebrovascular disease

    International Nuclear Information System (INIS)

    The brain is supplied by two pairs of arteries, the large carotid arteries anteriorly and the vertebral arteries (so called because they are so close to the vertebral column) posteriorly. All four arteries enter the skull at the base of the brain and are connected in the arterial circle of Willis, a unique safety device that permits arterial blood to cross from one side to the other, in case of need, or from front to back or back to front. When one inflow artery is narrowed or occluded, flow increases via other inflow arteries to maintain pressure and flow within the circle. This collateral circulation is also assisted by inflow to the circle through the orbit. When needed, arterial blood reaches the circle of Willis from the face by traversing the orbit in reverse direction. In unusual circumstances, blood in the circle of Willis can leave the brain and flow down the vertebral artery-the so-called ''vertebral steal.'' The authors provide a detailed description of the anatomy, particularly as it affects the signs, symptoms, and noninvasive diagnosis of cerebrovascular disease

(2 Does government intervention make a difference in what these transacting parties would otherwise have decided or chosen in its absence? Approach: An internet literature search was performed, using query term combinations, to identify aspirin-related studies. The search yielded 51 juried publications that met our predetermined criteria for inclusion and thematic analysis. Results: Some variance exists within the surveyed literature concerning government intervention in aspirin prophylaxis for cardiovascular and cerebrovascular events, particularly heart attacks, strokes and cardiovascular death. This study identified 4 instances of market failure that offer some of the strongest theoretical and practical considerations for public policy intervention in aspirin’s pharmacological information. However, there is also indication that the sense of increased protection arising from safety regulations could stimulate risky behavior that nullifies their net protective effects or benefits. Conclusion: It is not clear either from the surveyed literature or existing economic theory if, ceteris paribus, mandatory safety information is necessary to alter or modify the marginal propensity of a physician to recommend and a patient to purchase, aspirin. The study suggested the need for policy reinforcements to any safety information regulation, if market failures are to be effectively addressed and risk compensating behavior reduced.

    Cerebrovascular reactivity to CO2 inhalation and voluntary hyperventilation was studied in seven normotensive subjects and nine hypertensive patients without clinical or angiographical signs of arteriosclerosis. Cerebral blood flow (CBF) was measured by the intracarotid 133Xe clearance method and...... calculated as the initial slope index. Three to five CBF measurements were made in each patient in the PaCO2 range of 20 to 55 mm Hg. No difference was observed in reactivity between hypertensive and normotensive patients, either during CO2 inhalation or during hyperventilation. The shape of the CBF:PaCO2...... curve suggested a decrease in reactivity below a PaCO2 of 30 to 35 mm Hg in both groups. Above a PaCO2 of 35 mm Hg, exponential regression analysis yielded a mean reactivity of 6 +/- 2%, whereas below a PaCO2 of 30 mm Hg it was about 2%. The rise in CBF during CO2 inhalation was not influenced by the...

  3. Pioglitazone improves reversal learning and exerts mixed cerebrovascular effects in a mouse model of Alzheimer's disease with combined amyloid-β and cerebrovascular pathology.

    Directory of Open Access Journals (Sweden)

    Panayiota Papadopoulos

    Full Text Available Animal models of Alzheimer's disease (AD are invaluable in dissecting the pathogenic mechanisms and assessing the efficacy of potential new therapies. Here, we used the peroxisome proliferator-activated receptor gamma agonist pioglitazone in an attempt to rescue the pathogenic phenotype in adult (12 months and aged (>18 months bitransgenic A/T mice that overexpress a mutated human amyloid precursor protein (APPSwe,Ind and a constitutively active form of transforming growth factor-β1 (TGF-β1. A/T mice recapitulate the AD-related cognitive deficits, amyloid beta (Aβ and cerebrovascular pathologies, as well as the altered metabolic and vascular coupling responses to increased neuronal activity. Pioglitazone normalized neurometabolic and neurovascular coupling responses to sensory stimulation, and reduced cortical astroglial and hippocampal microglial activation in both age groups. Spatial learning and memory deficits in the Morris water maze were not rescued by pioglitazone, but reversal learning was improved in the adult cohort notwithstanding a progressing Aβ pathology. While pioglitazone preserved the constitutive nitric oxide synthesis in the vessel wall, it unexpectedly failed to restore cerebrovascular reactivity in A/T mice and even exacerbated the dilatory deficits. These data demonstrate pioglitazone's efficacy on selective AD hallmarks in a complex AD mouse model of comorbid amyloidosis and cerebrovascular pathology. They further suggest a potential benefit of pioglitazone in managing neuroinflammation, cerebral perfusion and glucose metabolism in AD patients devoid of cerebrovascular pathology.

    Alzheimer's disease (AD) is a leading cause of death and disability among older adults. Modifiable vascular risk factors for AD (VRF) include obesity, hypertension, type 2 diabetes mellitus, sleep apnea, and metabolic syndrome. Here, interactions between cerebrovascular function and development of AD are reviewed, as are interventions to improve cerebral blood flow and reduce VRF. Atherosclerosis and small vessel cerebral disease impair metabolic regulation of cerebral blood flow and, along with microvascular rarefaction and altered trans-capillary exchange, create conditions favoring AD development. Although currently there are no definitive therapies for treatment or prevention of AD, reduction of VRFs lowers the risk for cognitive decline. There is increasing evidence that brief repeated exposures to moderate hypoxia, i.e. intermittent hypoxic training (IHT), improve cerebral vascular function and reduce VRFs including systemic hypertension, cardiac arrhythmias, and mental stress. In experimental AD, IHT nearly prevented endothelial dysfunction of both cerebral and extra-cerebral blood vessels, rarefaction of the brain vascular network, and the loss of neurons in the brain cortex. Associated with these vasoprotective effects, IHT improved memory and lessened AD pathology. IHT increases endothelial production of nitric oxide (NO), thereby increasing regional cerebral blood flow and augmenting the vaso- and neuroprotective effects of endothelial NO. On the other hand, in AD excessive production of NO in microglia, astrocytes, and cortical neurons generates neurotoxic peroxynitrite. IHT enhances storage of excessive NO in the form of S-nitrosothiols and dinitrosyl iron complexes. Oxidative stress plays a pivotal role in the pathogenesis of AD, and IHT reduces oxidative stress in a number of experimental pathologies. Beneficial effects of IHT in experimental neuropathologies other than AD, including dyscirculatory encephalopathy, ischemic stroke injury, audiogenic

    Human underwater breath-hold diving is a fascinating example of applied environmental physiology. In combination with swimming, it is one of the most popular forms of summer outdoor physical activities. It is performed by a variety of individuals ranging from elite breath-hold divers, underwater hockey and rugby players, synchronized and sprint swimmers, spear fishermen, sponge harvesters and up to recreational swimmers. Very few data currently exist concerning the influence of regular breath holding on possible health risks such as cerebrovascular, cardiovascular and respiratory diseases. A literature search of the PubMed electronic search engine using keywords 'breath-hold diving' and 'apnoea diving' was performed. This review focuses on recent advances in knowledge regarding possibly harmful physiological changes and/or potential health risks associated with breath-hold diving. Available evidence indicates that deep breath-hold dives can be very dangerous and can cause serious acute health problems such a collapse of the lungs, barotrauma at descent and ascent, pulmonary oedema and alveolar haemorrhage, cardiac arrest, blackouts, nitrogen narcosis, decompression sickness and death. Moreover, even shallow apnoea dives, which are far more frequent, can present a significant health risk. The state of affairs is disturbing as athletes, as well as recreational individuals, practice voluntary apnoea on a regular basis. Long-term health risks of frequent maximal breath holds are at present unknown, but should be addressed in future research. Clearly, further studies are needed to better understand the mechanisms related to the possible development or worsening of different clinical disorders in recreational or competitive breath holding and to determine the potential changes in training/competition regimens in order to prevent these adverse events.

    The aim of the presented work is to investigate the mechanisms of involvement of cerebral circulation in pathogenesis of space motion sickness. In experiments on chronic rabbits the 2-hours rocking and antiorthostasis served as a model of influences of the zero-gravity conditions intracranial hemo- and liquorodynamics. Cerebrovascular reactivity was evaluated as a response of cerebral blood flow and intracerebral rheoencephalography to functional loads (photostimulation, CO 2-inhalation, Stookey test). Shifts of water balance in the brain tissue has been assessed by means of three-frequency brain electrical impedance. Rocking plus antiorthostasis resulted in decrease of the cerebrovascular reactivity and hyperhydration. The data obtained show a significant decrease of compensatory abilities of the cerebrovascular system under the zero-gravity conditions.

  19. The relationship between cerebrovascular disease and homocysteine, folate and vitamin B12 in serum

    International Nuclear Information System (INIS)

    To investigate the relationship between cerebrovascular disease and the serum levels of homocysteine(Hcy), folate and vitamin B12, the serum levels of Hcy, folate and vitamin B12 in 148 patients with cerebrovascular disease were measured by fluorescence polarization immuno- assay and chemiluminescence and were compared with those in healthy controls. The result showed that the serum Hcy levels in patients with cerebral infarction, cerebral hemorrhage and vertebrobasilar ischemiay were significantly higher than those in healthy controls (P12 levels were signifieantly lower (P0.05). No significantly higher ratio of increased Hcy levels was observed in patient with complications (P> 0.05). Our conclusion is that hyperhomocysteinemia may be a new and an independent risk factor for cerebrovascular disease. The serum Hcy level is correlated with decreased levels of folate and vitamin B12 but not obviously correlated with hypertension, diabetes and coronary heart disease. (authors)

    Full Text Available Ecological damage, including global climate change, is commonly connected to practices and behaviors associated with economic activity and the Treadmill of Production (ToP. Less attention is paid to the connection between the military and environmental degradation, but recently the Treadmill of Destruction (ToD has been documented as a global phenomenon with negative environmental effects. The ToD directly and indirectly contributes to environmental problems on many fronts, but one of the least obvious means by which the U.S. military influences the environment is through its policies supporting the "war on drugs. " The U.S. military aids Latin American countries, particularly Colombia, in the war on drugs in a number of capacities, including military support and training, weaponry, fumigation of crops, and logistical and surveillance support. The effort of the United States to curb the proliferation of illegal drug crops in Colombia is the most direct role that the military has played in this effort. Within the context of the "war on drugs" the United States is now engaged in risk-transfer militarism in which the consequences of this military action are borne by the Global South. We document the scope, magnitude, and consequences of the ToD in the war on drugs and the ways it negatively impacts the environment. Our argument reframes the ToD by emphasizing the role of risk-transfer militarism within the emergence of "new" wars as represented in the case of Colombia.

    Patients who have cerebrovascular disease and vascular insufficiency routinely have neurosurgical and nonneurosurgical procedures. Anesthetic priorities must provide a still bloodless operative field while maintaining cardiovascular stability and renal function. Patients who have symptoms or a history of cerebrovascular disease are at increased risk for stroke, cerebral hypoperfusion, and cerebral anoxia. Type of surgery and cardiovascular status are key concerns when considering neuroprotective strategies. Optimization of current condition is important for a good outcome; risks must be weighed against perceived benefits in protecting neurons. Anesthetic use and physiologic manipulations can reduce neurologic injury and assure safe and effective surgical care when cerebral hypoperfusion is a real and significant risk. PMID:16935193

We aim to determine the epidemiology of non-fatal cerebrovascular stroke (CVS and transient ischemic attacks (TIAs in Al Quseir City, Red Sea, Egypt. Methods: The total population (n=33,285 was screened through a door to door study by three specialists of neurology and 15 female social workers (for demographic data collection. All suspected stroke patients were subjected to a full clinical examination, computerized tomography (CT and/or magnetic resonance imaging (MRI of their brain, blood sugar, lipogram, serum uric acid, complete blood cells, blood urea, and serum creatinine, as well as evaluated by Barthel Index and Scandinavian Stroke Scale. Carotid doppler, echocardiography, and thyroid functions were done for selected cases. Results: CVS was recorded among 130 patients out of 19,848 subjects aged 20 years and more, yielding a total prevalence of 6.55/1,000 population. From June 1, 2010 to May 31, 2011, 36 patients were recorded to have stroke within 1-year, yielding an incidence rate of 1.81/1,000. Prevalence and incidence rates were higher among males than females, and both indices increased steadily with advancing age to reach the highest prevalence (37.02/1,000 and incidence rate (9.5/1,000 among aged persons 60 years and more. Conclusion: The prevalence of non-fatal stroke in Al Quseir city (6.55/1,000 was at the lower range of that recorded in developing countries (5–10/1,000 and slightly higher than that recorded in industrialized countries (5/1,000 population.

    Full Text Available Immune cells (IC play a crucial role in murine stroke pathophysiology. However, data are limited on the role of these cells in ischemic stroke in humans. We therefore aimed to characterize and compare peripheral IC subsets in patients with acute ischemic stroke/transient ischemic attack (AIS/TIA, chronic cerebrovascular disease (CCD and healthy volunteers (HV. We conducted a case-control study of patients with AIS/TIA (n = 116 or CCD (n = 117, and HV (n = 104 who were enrolled at the University Hospital Würzburg from 2010 to 2013. We determined the expression and quantity of IC subsets in the three study groups and performed correlation analyses with demographic and clinical parameters. The quantity of several IC subsets differed between the AIS/TIA, CCD, and HV groups. Several clinical and demographic variables independently predicted the quantity of IC subsets in patients with AIS/TIA. No significant changes in the quantity of IC subsets occurred within the first three days after AIS/TIA. Overall, these findings strengthen the evidence for a pathophysiologic role of IC in human ischemic stroke and the potential use of IC-based biomarkers for the prediction of stroke risk. A comprehensive description of IC kinetics is crucial to enable the design of targeted treatment strategies.

    OBJECTIVE. This article describes a performance-based measure of executive function, the Multiple Errands Test-Revised (MET-R), and examines its ability to discriminate between people with mild cerebrovascular accident (mCVA) and control participants. METHOD. We compared the MET-R scores and measures of CVA outcome of 25 participants 6 mo post-mCVA and 21 matched control participants. RESULTS. Participants with mCVA showed no to minimal impairment on measures of executive function at hospital discharge but reported difficulty with community integration at 6 mo. The MET-R discriminated between participants with and without mCVA (p ≤ .002). CONCLUSION. The MET-R is a valid and reliable measure of executive functions appropriate for the evaluation of clients with mild executive function deficits who need occupational therapy to fully participate in community living.

It is responsible for up to 10% of deaths worldwide, is a major cause of disability, and represents an area of real unmet clinical need. Acute cerebrovascular disease is multifactorial with many mechanisms contributing to a complex pathophysiology. One of the major processes worsening disease severity and outcome is inflammation. Pro-inflammatory cytokines of the interleukin (IL-1 family are now known to drive damaging inflammatory processes in the brain. The aim of this review is to discuss the recent literature describing the role of IL-1 in acute cerebrovascular disease and to provide an update on our current understanding of the mechanisms of IL-1 production. We also discuss the recent literature where the effects of IL-1 have been targeted in animal models, thus reviewing potential future strategies that may limit the devastating effects of acute cerebrovascular disease.Keywords: cerebral ischemia, stroke, inflammation, microglia, interleukin-1, caspase-1

    Endothelial dysfunction and aberrations of haemostasis play an important part in development of cerebrovascular disorders in patients with diabetes mellitus. Such factors as hyper- and hypoglycemia, hyperinsulinism, insulin resistance and excessive weight affect progression of microcirculation deficiency and cerebral ischemia. Transcranial Doppler ultrasound examination is useful as a noninvasive method of hemodynamic assessment.

    Background. A necktie may elevate intracranial pressure through compression of venous return. We hypothesised that a tight necktie would deleteriously alter cerebrovascular reactivity. Materials and Methods. A necktie was simulated using bespoke apparatus comprising pneumatic inner-tube with aneroid pressure-gauge. Using a randomised crossover design, cerebrovascular reactivity was measured with the "pseudo-tie" worn inflated or deflated for 5 minutes (simulating tight/loose necktie resp.). Reactivity was calculated using breath hold index (BHI) and paired "t" testing used for comparative analysis. Results. We enrolled 40 healthy male volunteers. There was a reduction in cerebrovascular reactivity of 0.23 units with "tight" pseudotie (BHI loose 1.44 (SD 0.48); BHI tight 1.21 (SD 0.38) P < .001). Conclusion. Impairment in cerebrovascular reactivity was found with inflated pseudo-tie. However, mean BHI is still within a range of considered normal. The situation may differ in patients with vascular risk factors, and confirmatory work is recommended. PMID:21076611

    Full Text Available Este estudo sugere um modelo para o entendimento da relação entre diferentes missões militares e diferentes níveis de cumprimento ou não cumprimento. O cumprimento tem a ver com a natureza da missão em si e se a experiência e o treinamento prévio dos militares são compatíveis com as funções que lhe são atribuídas. Quanto maior a diferença entre a missão e a capacidade profissional para realizá-la, será menos provável que os militares estejam favoravelmente predispostos a cumpri-las. A exceção a essa regra reside naquelas onde estão presentes consideráveis benefícios potenciais para uma missão nova e não familiar. Caso contrário, onde a desvantagem é grande, os militares irão fugir de suas funções, negociar, ou estabelecer condições como preço para o cumprimento da missão. Eu suponho que o cumprimento da missão será maior nos casos de manutenção da paz, de ação cívica e de missões de destruição de drogas. A negociação é mais provável nos casos de contra-insurgência e o não-cumprimento é mais provável para missões anti-crimes e de manutenção da ordem pública.This study suggests a framework for understanding the relationship between different military missions and differing levels of compliance or non-compliance. Compliance has to do with the nature of the mission itself and whether the military’s prior training and experience is compatible with the duties assigned to it. The greater the gap between the mission and the professional capacity to carry it out, the less likely the military will be favorably predisposed. The exception to that rule is where the potential benefits to a new and unfamiliar mission are considerable. Otherwise where the gap is great, the military will either shirk its duties, bargain, or set conditions as the price for mission fulfillment. I hypothesize that mission compliance will be greatest for peacekeeping, civic action and crop eradication missions. Bargaining is

  15. Arquitectura militar en la región de Jaina, Campeche, México. Falsedades en la historia defensiva colonial

    Victoria Ojeda, Jorge

    1999-06-01

    Full Text Available El autor pasa revista a dos observaciones hechas sobre las fortificaciones en la región de Jaina que considera incorrectas, puesto que parten de la premisa de que estas construcciones datan del período colonial. Si bien un conocido mapa de las construcciones militares en la isla ha sido utilizado para fecharlas en el siglo XVIII, la información que lo acompaña es apócrifa. En la segunda parte, trata de la antigüedad de las fortificaciones del camino a Jaina, fechadas en los siglos XVII y XVIII; tras sopesar las distintas fechas posibles, concluye que las fortificaciones son, en realidad, posteriores a 1821. Esta corrección evitará errores en la evaluación de las estrategias de defensa coloniales en la península de Yucatán.

  1. 7-T MRI in Cerebrovascular Diseases: Challenges to Overcome and Initial Results.

    2016-04-01

    Magnetic resonance imaging (MRI) plays a key role in the investigation of cerebrovascular diseases. Compared with computed tomography (CT) and digital subtraction angiography (DSA), its advantages in diagnosing cerebrovascular pathology include its superior tissue contrast, its ability to visualize blood vessels without the use of a contrast agent, and its use of magnetic fields and radiofrequency pulses instead of ionizing radiation. In recent years, ultrahigh field MRI at 7 tesla (7 T) has shown promise in the diagnosis of many cerebrovascular diseases. The increased signal-to-noise ratio (SNR; 2.3x and 4.7x increase compared with 3 and 1.5 T, respectively) and contrast-to-noise ratio (CNR) at this higher field strength can be exploited to obtain a higher spatial resolution and higher lesion conspicuousness, enabling assessment of smaller brain structures and lesions. Cerebrovascular diseases can be assessed at different tissue levels; for instance, changes of the arteries feeding the brain can be visualized to determine the cause of ischemic stroke, regional changes in brain perfusion can be mapped to predict outcome after revascularization, and tissue damage, including old and recent ischemic infarcts, can be evaluated as a marker of ischemic burden. For the purpose of this review, we will discriminate 3 levels of assessment of cerebrovascular diseases using MRI: Pipes, Perfusion, and Parenchyma (3 Ps). The term Pipes refers to the brain-feeding arteries from the heart and aortic arch, upwards to the carotid arteries, vertebral arteries, circle of Willis, and smaller intracranial arterial branches. Perfusion is the amount of blood arriving at the brain tissue level, and includes the vascular reserve and perfusion territories. Parenchyma refers to the acute and chronic burden of brain tissue damage, which includes larger infarcts, smaller microinfarcts, and small vessel disease manifestations such as white matter lesions, lacunar infarcts, and microbleeds

    Full Text Available Thrombectomy is a common procedure performed to declot thrombosed dialysis arteriovenous fistula (AVF or arteriovenous graft (AVG. Complications associated with access thrombectomy like pulmonary embolism have been reported, but paradoxical embolism is extremely rare. We report a case of a 74-year-old black man with past medical history significant for end-stage renal disease (ESRD, atrial fibrillation on anticoagulation with warfarin, who presented to our hospital with lethargy, aphasia, and right-sided hemiparesis following thrombectomy of a clotted AVG. Computed tomography (CT scan of brain showed a hypodensity within the left posterior parietal lobe. INR was 2.0 on admission. Echocardiogram revealed a normal sized left atrium with no intracardiac thrombus, and bubble study showed the presence of right-to-left shunting. These findings suggest that the stroke occurred as a result of an embolus originating from the AVG. Paradoxical cerebral embolism is uncommon but can occur after thrombectomy of clotted vascular access in ESRD patients. Clinicians and patients should be aware of this serious and potentially fatal complication of vascular access procedure.

    Under the current system, orthopaedic trauma surgeons must work in some form of hospital setting as our primary service involves treatment of the trauma patient. We must not forget that just as a trauma center cannot exist without our services, we cannot function without their support. As a result, a clear understanding of the balance between physicians and hospitals is paramount. Historical perspective enables physicians and hospital personnel alike to understand the evolution of hospital-physician relationship. This process should be understood upon completion of this chapter. The relationship between physicians and hospitals is becoming increasingly complex and multiple forms of integration exist such as joint ventures, gain sharing, and co-management agreements. For the surgeon to negotiate well, an understanding of hospital governance and the role of the orthopaedic traumatologist is vital to success. An understanding of the value provided by the traumatologist includes all aspects of care including efficiency, availability, cost effectiveness, and research activities. To create effective and sustainable healthcare institutions, physicians and hospitals must be aligned over a sustained period of time. Unfortunately, external forces have eroded the historical basis for the working relationship between physicians and hospitals. Increased competition and reimbursement cuts, coupled with the increasing demands for quality, efficiency, and coordination and the payment changes outlined in healthcare reform, have left many organizations wondering how to best rebuild the relationship. The principal goal for the physician when partnering with a hospital or healthcare entity is to establish a sustainable model of service line management that protects or advances the physician's ability to make impactful improvements in quality of patient care, decreases in healthcare costs, and improvements in process efficiency through evidence-based practices and protocols.

    It is known that asymptomatic MRI lesions of the brain are found in elderly subjects, but the significance of the lesions has not been determined. In previous reports, the prevalence of MRI lesions varied from 11% to 59%, but many of the authors indicated a close relationship with cerebrovascular risk factors. We evaluated 76 elderly subjects (over 60 years old, average age [+-]SD was 66.7[+-]4.5) without a history of cerebrovascular disease and dementia, and determined the prevalence of periventricular (PVH), white matter (WMH) and pontine (PH) hyperintensity and risk factors. The severity of MRI lesion was evaluated in T2-weighted images by Fazekas' scoring method of MRI hyperintense lesions. PVH, WMH and PH were graded visually from 0 to 3 by the author and these points are added to the MRI score. In T1-weighted images, we also measured the diameter of the third ventricle, frontal horn and body of the lateral ventricle. Our results were that 62% of subjects had PVH, 64% had WMH and 8% had PH. In regard to risk factors, 38% of subjects had hypertension, 17% had diabetes mellitus, 8% had ischemic heart disease. The PVH (+) group was significantly older (p<0.01) and had larger lateral ventricles (p<0.05) than the PVH (-) group. The WMH (+) group was significantly older (p<0.05) and had higher risk of cerebrovascular disease (0.05) than the WMH (-) group. The MRI score was related, but not significantly, to a history of hypertension, diabetes mellitus and ischemic heart disease. The MRI score and index of ventricular enlargement correlated with age (p<0.05). In conclusion, PVH was related to aging and cerebrovascular risk factors. Therefore, PVH and WMH were suspected to have different pathogenesis and WMH was more closely related to risk factors. Our scoring method permits evaluation and comparison of MRI lesions of different groups. (author).

Near-infrared spectroscopy (NIRS) offers the potential for non-invasive, continuous bedside measurement of surrogates for these processes. Interest has grown in applying this technique to interpret cerebrovascular pressure reactivity (CVPR), a surrogate of the brain's ability to autoregulate blood flow. We describe a physiological model-based...

    Recently, several high-impact reviews suggest that regular aerobic exercise is beneficial for maintaining cognitive function in aging adults. Higher cerebral blood flow and/or cerebrovascular reactivity may explain the favorable effect of exercise on cognition. In addition, prostaglandin-mediated vasodilator responses may be influenced by regular exercise. Therefore, our purpose was to evaluate middle cerebral artery (MCA) vasodilator responses in healthy adults before and after cyclooxygenas...

    Pneumoconiosis is a parenchymal lung disease that develops through the inhalation of inorganic dust at work. Cerebrovascular and cardiovascular events are leading causes of mortality and adult disability worldwide. This retrospective cohort study investigated the association between pneumoconiosis, and cerebrovascular and cardiovascular events by using a nationwide population-based database in Taiwan. The data analyzed in this study was retrieved from the Taiwan National Health Insurance Research Database. We selected 6940 patients with pneumoconiosis from the database as our study cohort. Another 27,760 patients without pneumoconiosis were selected and matched with those with pneumoconiosis according to age and sex as the comparison cohort. We used univariate and multivariate Cox proportional-hazard regression analyses to determine the association between pneumoconiosis and the risk of cerebrovascular and cardiovascular events after adjusting for medical comorbidities. After adjustment for age, sex, and comorbidities, the patients with pneumoconiosis exhibited a significantly higher incidence of ischemic stroke (hazard ratio [HR] 1.14, 95% confidence interval [CI] 1.05-1.24) than did those without pneumoconiosis. The incidence of hemorrhagic stroke was higher, but not significant, in the pneumoconiosis patients (HR 1.20, 95% CI 0.99-1.46). No statistically significant differences were observed between the pneumoconiosis and nonpneumoconiosis groups in acute coronary syndrome (HR 1.10, 95% CI 0.95-1.26). The findings of this study reveal an association between pneumoconiosis and a higher risk of cerebrovascular events after adjustment for comorbidities. Healthcare providers should control the related risk factors for primary prevention of stroke in pneumoconiosis patients. PMID:26945404

    Full Text Available Introduction: Tremor can occur as a part of the clinical feature of cerebrovascular diseases. Many patients with cerebral stroke have cardiovascular diseases as a comorbidity or complication of stroke; sometimes cardiovascular events can lead to embolic stroke. Aim: To present types of tremor in patients with cerebrovascular diseases and cardiovascular events and diabetes mellitus type 2, clinical characteristics of tremor and investigations used. Material and methods: In our study we included 36 patients, 24 men and 12 women, that were examined and followed for 3 years, from 2012-2015. All patients were subjected to the following investigations: neurological examination, laboratory analysis, computerized tomography of brain, magnetic resonance imaging and electroencephalography. In cardiovascular patients we also performed Doppler sonography of carotid arteries, electrocardiography, cardiac ultrasound. The patients were examined and treated by cardiologists. Results: Of all patients 22% had cerebral infarction, 41% atherosclerosis, 36% multiple lacunar infarctions and 28% diabetes mellitus type 2. Three patients with cerebral infarction had chorea, hemiballismus, dystonia and dystonic tremor, three had postural tremor and two cerebellar intention tremor. Atherosclerotic patients had atherosclerotic action tremor, while diabetic patients predominantly presented with action-type tremor. Electroencephalography showed irritative basic brain activity with slow waves, while carotid arteries stenosis was diagnosed by Doppler sonography. Computerized tomography of the brain and magnetic resonance imaging revealed cerebrovascular diseases in certain areas. Patients with cardiomyopathy, rhythm disorders, high blood pressure, hyperlipidemia was investigated and medically treated by a cardiologist. Conclusion: In cerebrovascular diseases different types of tremor can occur as the result of the damage of the extrapyramidal system.

    In a survey of Welsh hospitals, 96 patients were identified who had been continuously resident for between 4 months and 20 years; they were aged between 15 and 65 years on admission. The commonest causes for such admissions were cerebrovascular accidents, trauma and diabetes. Suitable facilities for the long-term care and rehabilitation of such severely disabled young people are very limited in Wales, and in an era when rehabilitation should be possible they have been forgotten.

    The aim of the present work was to examine possible genetic risk factors related to the occurrence of cerebrovascular disease (CVD) in Brazilian population, the frequency of β(S)-globin gene haplotypes and co-inheritance with α-thalassemia (-α(3.7kb)) and single nucleotide polymorphism of methylenetetrahydrofolate reductase (MTHFR-C677T), Factor V Leiden (FV-G1691A) and prothrombin (PT-G20210A) genes in children from Rio de Janeiro. Ninety four children with sickle cell anemia (SCA) were included, 24 patients with cerebrovascular involvement and 70 patients without CVD as control group. The mean age of children at the time of the cerebrovascular event was similar to the control group. The frequency of -α(3.7kb) thalassemia was similar in both groups (p=0.751). Children with Bantu/Atypical β(S)-globin gene haplotype presented 15 times more chance (OR=15.4 CI 95% 2.9-81.6) of CVD than the other β(S)-globin gene haplotypes. The C677T polymorphism of MTHFR gene was similar in both groups (p=0.085). No mutation in the FV Leiden or PT genes was found. A large study seems necessary to establish the role of these genetic polymorphisms in Brazilian miscegenated population. PMID:21755116

  16. Two-dimensional thick-slice MR digital subtraction angiography for assessment of cerebrovascular occlusive diseases

    International Nuclear Information System (INIS)

    Although spatial resolution of current MR angiography is excellent, temporal resolution has remained unsatisfactory. We evaluated clinical applicability of 2D thick-slice, contrast-enhanced subtraction MR angiography (2D-MR digital subtraction angiography) with sub-second temporal resolution in cerebrovascular occlusive diseases. Twenty-five patients with cerebrovascular occlusive diseases (8 moyamoya diseases, 10 proximal internal carotid occlusions, and 2 sinus thromboses) were studied with a 1.5-T MR unit. The MR digital subtraction angiography (MRDSA) was performed per 0.97 s continuously just after a bolus injection of 15 ml of gadolinium chelates up to 40 s in sagittal (covering hemisphere) or coronal planes. Subtraction images were generated at a workstation. We evaluated imaging quality and hemodynamic information of MRDSA in comparison with those of routine MR imaging, non-contrast MR angiography, and X-ray intra-arterial DSA. Major cerebral arteries, all of the venous sinuses, and most tributaries were clearly visualized with 2D MRDSA. Also, pure arterial phases were obtained in all cases. The MRDSA technique demonstrated prolonged circulation in sinus thromboses, distal patent lumen of proximal occlusion, and some collateral circulation. Such hemodynamic information was comparable to that of intra-arterial DSA. Two-dimensional thick-slice MRDSA with high temporal resolution has a unique ability to demonstrate cerebral hemodynamics equivalent to that of intra-arterial DSA and may play an important role for evaluation of cerebrovascular occlusive diseases.

    Haze is an atmospheric phenomenon in which dry particulate pollutants obscure the sky. Haze has been associated with chronic diseases, but its relationship with acute diseases is less clear. We aimed to determine the association between haze and acute cardiovascular, cerebrovascular, and respiratory diseases, in order to determine the influence of haze on human health. We compared the number of cases of acute cardiovascular, cerebrovascular, and respiratory diseases in Beijing Emergency Center between 2006 and 2013, with haze data from Beijing Observatory. The relationship between the number of hazy days and the number of cases of the above types of diseases was analyzed using univariate analyses. Both the number of cases and the number of hazy days showed a rising trend. The average number of cases per day for all three diseases was higher on hazy days than on non-hazy days. There was a positive correlation between the number of hazy days and the number of cases, and this correlation showed a hysteretic quality. Haze has an influence on acute cardiovascular (CVDs), cerebrovascular (CBDs), and respiratory system (RSDs) diseases. Haze seems to have an additive effect, since the associations between haze and number of cases were stronger in the following month than in the preceding month. The increasing trend in the number of hazy days might worsen the problem of haze-related diseases. PMID:25292298

  18. Cognitive performance correlates with cerebrovascular impairments in multi-infarct dementia

    International Nuclear Information System (INIS)

    Cerebral blood flow (CBF) was measured by the 133Xe inhalation method in patients with multi-infarct dementia (MID, N = 26), Alzheimer's dementia (AD, N = 19), and among age-matched, neurologically normal, healthy volunteers (N = 26). Cognitive performance was assessed in all subjects using the Cognitive Capacity Screening Examination (CCSE). Cerebral vasomotor responses were calculated from differences in values of mean hemispheric gray matter blood flow (Delta CBF) measured during inhalation of 100% oxygen (hyperoxia) compared with CBF measured while breathing room air. Significant correlations were found between CCSE performance and vasomotor responsiveness in patients with MID (P less than .01), but not in patients with AD or in neurologically normal volunteers. Loss of vasomotor responsiveness is an indicator of cerebrovascular disease with rigidity and/or loss of reactivity of cerebral vessels, which impairs cerebrovascular responses to situational demands and predisposes to cerebral ischemia. Loss of cerebral vasomotor responsiveness among MID patients, which is a biologic marker of cerebrovascular disease, provides confirmatory evidence of the vascular etiology of MID and assists in separating MID from AD patients

    Full Text Available The problem of cerebrovascular lesions takes on even greater significance with the higher prevalence of both acute and chronic forms of cerebrovascular diseases (CVD. Cognitive dysfunctions that have a pronounced negative impact on the quality of life in patients hold a special place among the various neurological symptoms resulting from cerebrovascular lesions. The incidence of vascular dementia increases with age. The paper considers the main issues of the etiology, pathogenesis and classification of vascular cognitive impairments (VCIs. It proposes criteria for the diagnosis of VCIs in the early stages of the disease. Potentially modifiable factors, such as hypertension, coronary heart disease, orthostatic hypotension, diabetes mellitus, hypercholesterolemia, hyperhomocysteinemia, obesity, et al., are indicated to have a special place among the main etiological causes of VCIs. The timely detection of etiological factors and the assessment of their role in the development of cognitive impairments (CI in CVD form the basis for managing these patients. The issues of treating CI no dementia in patients with CVD are considered. These included the administration of nootropic, vasoactive drugs, as well as agents that exert a modulatory effect on the cholinergic and glutamatergic systems. The use of neuroprotective and neurotrophic drugs is noted to be promising in terms of the multicomponent mechanism of their action.

    Sickle cell disease (SCD) is a genetic disorder which adversely affects cerebrovascular health. Previous studies have demonstrated regional cortical thinning in SCD. However, the reason behind regional reductions in cortical thickness remains unclear. Therefore, we aimed to explore the possible link between the state of cerebrovascular health and cortical thickness. In this study, we obtained magnetic resonance (MR) based measures of cerebrovascular reactivity (CVR), a measure of vascular health, and cortical thickness in SCD patients (N=60) and controls of similar age and similar gender ratio (N=27). The group comparison analysis revealed significant regionally specific reductions in CVR and cortical thickness in the SCD group compared to the controls. In addition, a regional association analysis was performed between CVR and cortical thickness in the SCD group which revealed a significant regional association in several brain regions with the highest strength of association observed in the left cuneus, right post central gyrus and the right temporal pole. The regional association analysis revealed that significant associations were found in brain regions with high metabolic activity (anterior cingulate, posterior cingulate, occipital gyrus, precuneus) thus demonstrating that these regions could be most vulnerable to structural damage under hypoxic conditions.

    Recently, several high-impact reviews suggest that regular aerobic exercise is beneficial for maintaining cognitive function in aging adults. Higher cerebral blood flow and/or cerebrovascular reactivity may explain the favorable effect of exercise on cognition. In addition, prostaglandin-mediated vasodilator responses may be influenced by regular exercise. Therefore, our purpose was to evaluate middle cerebral artery (MCA) vasodilator responses in healthy adults before and after cyclooxygenase inhibition. A total of 16 young (26 ± 6 yr; 8 males, 8 females) and 13 older (64 ± 6 yr; 7 males, 6 females) healthy adults participated in the study. Aerobic fitness was determined by maximal aerobic capacity (Vo2max) on a cycle ergometer. MCA velocity (MCAv) was measured at baseline and during stepped hypercapnia (2%, 4%, and 6% FiCO2) before and after cyclooxygenase inhibition using indomethacin. To account for differences in blood pressure, cerebrovascular conductance index (CVCi) was calculated as MCAv/mean arterial pressure. Cerebrovascular reactivity slopes were calculated from the correlation between either MCAv or CVCi and end-tidal CO2. Young adults demonstrated greater MCAv reactivity (1.61 ± 0.17 vs. 1.06 ± 0.15 cm·s(-1)·mmHg(-1); P exercise and improved cognitive function in aging adults. PMID:23471946

    Full Text Available RESUMEN: En este artículo se analizan las relaciones entre el reino de Aragón y la monarquía de los Austrias en el ámbito de la colaboración aragonesa en las empresas militares de la Corona durante este periodo. Aunque las relaciones fueron generalmente amistosas, éstas no estuvieron exentas de problemas y disputas cuando la Corona demandaba subsidios. Las solicitudes de los Austrias planteadas sobre Aragón a lo largo del siglo XVI, experimentarían un notable incremento en la centuria siguiente. La nueva apertura del conflicto con Francia en 1635 y, especialmente, la Guerra de Cataluña producida entre 1640 y 1652 obligaron a los Austrias a volcarse sobre sus reinos en solicitud de ayuda financiera y asistencia militar. El avance de las armas francesas y la invasión de Aragón, sucedida en 1641, alarmaron a la monarquía hispánica. Los aragoneses fueron requeridos para apoyar los nuevos planes de la Monarquía bajo la premisa de hacerlo en «defensa del Reino». Las demandas de la Corona continuaron durante toda la centuria hasta la llegada de los Borbones al poder, lo que representaba la abolición de los fueros aragoneses en 1711.ABSTRACT: The purpose of this article is to outline the relations between the kingdom of Aragon and the Habsburg monarchy regarding Aragonese collaboration in the military expedition during the Habsburg period. Despite the fact that relations were mainly friendly, some troubles and disputes existed when the Spanish monarch asked for subsidies. Habsburgs royal demands on the reign of Aragon in the sixteenth century reached an important. increasing during the next century. The renewal of war with France in 1635 and, especially, the War of Catalonia between 1640 and 1652 compelled Habsburgs to ask his kingdoms for financial support and military assistance. The progress of French arms and the invasion of Aragon happened in 1641 alarmed the Spanish monarchy. The Aragonese were called upon to support the new plans

    The phencyclidine derivative ketamine is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist with the thalamo-neocortical projection system as the primary site of action. Racemic ketamine consists of the enantiomers S(+)-ketamine and R(-)-ketamine. Racemic ketamine has never been considered an adequate anaesthetic agent in neurosurgical patients since it produces regionally specific stimulation of cerebral metabolism (CMRO2) and increases cerebral blood flow (CBF) and intracranial pressure (ICP). However, recent experiments suggest that both tracemic ketamine and S(+)-ketamine may reduce infarct size in animal models of incomplete cerebral ischaemia and brain injury. This experimental protective effect appears to be related to decreases in Ca++ influx and maintenance of brain tissue magnesium levels due to NMDA and quisqualate receptor blockade by ketamine. Studies in dogs have shown that racemic ketamine (2.0 mg/kg) increases CBF in the presence of the cerebral vasodilator N2O. In contrast, studies in rats without background anaesthesia showed increases in CBF after racemic ketamine (100 mg/kg i.p.). This suggests that the cerebrovascular effects of racemic ketamine are related to the pre-existing cerebrovascular tone induced by background anaesthetics. Cerebrovascular CO2 reactivity was maintained regardless of the baseline cerebrovascular resistance. There are several mechanisms by which racemic ketamine may increase CBF. It induces dose-dependent respiratory depression with consequent mild hypercapnia in spontaneously ventilating subjects. This produces vasodilation due to the intact cerebrovascular CO2 reactivity. Racemic ketamine also induces regional neuroexcitation, which leads to stimulation of cerebral glucose consumption in the limbic, extrapyramidal, auditory, and sensory-motor systems. This regional neuroexcitation with increased CMRO2 produces increases in CBF that can be blocked by infusion of barbiturates or benzodiazepines. However

    The influence of cardiac activity on the viscoelastic properties of intracranial tissue is one of the mechanisms through which brain-heart interactions take place, and is implicated in cerebrovascular disease. Cerebrovascular disease risk is not fully explained by current risk factors, including arterial compliance. Cerebrovascular compliance is currently estimated indirectly through Doppler sonography and magnetic resonance imaging (MRI) measures of blood velocity changes. In order to meet the need for novel cerebrovascular disease risk factors, we aimed to design and validate an MRI indicator of cerebrovascular compliance based on direct endogenous measures of blood volume changes. We implemented a fast non-gated two-dimensional MRI pulse sequence based on echo-planar imaging (EPI) with ultra-short repetition time (approx. 30-50 ms), which stepped through slices every approximately 20 s. We constrained the solution of the Bloch equations for spins moving faster than a critical speed to produce an endogenous contrast primarily dependent on spin volume changes, and an approximately sixfold signal gain compared with Ernst angle acquisitions achieved by the use of a 90° flip angle. Using cardiac and respiratory peaks detected on physiological recordings, average cardiac and respiratory MRI pulse waveforms in several brain compartments were obtained at 7 Tesla, and used to derive a compliance indicator, the pulsatility volume index (pVI). The pVI, evaluated in larger cerebral arteries, displayed significant variation within and across vessels. Multi-echo EPI showed the presence of significant pulsatility effects in both S0 and [Formula: see text] signals, compatible with blood volume changes. Lastly, the pVI dynamically varied during breath-holding compared with normal breathing, as expected for a compliance indicator. In summary, we characterized and performed an initial validation of a novel MRI indicator of cerebrovascular compliance, which might prove useful

  15. Prognostic value of myocardial perfusion single photon emission computed tomography for major adverse cardiac cerebrovascular and renal events in patients with chronic kidney disease: results from first year of follow-up of the Gunma-CKD SPECT multicenter study

    Patients with chronic kidney disease (CKD) have an increased risk of adverse cardio-cerebrovascular events. We examined whether stress myocardial perfusion single photon emission computed tomography (SPECT) provides reliable prognostic markers for these patients. In this multicenter, prospective cohort trial from the Gunma-CKD SPECT study protocol, patients with CKD [estimated glomerular filtration rate (eGFR) < 60 min/ml per 1.73 m2] undergoing stress 99mTc-tetrofosmin SPECT for suspected or possible ischemic heart disease were initially followed for 1 year, with the following study endpoints: primary, the occurrence of cardiac deaths (CDs), and secondary, major adverse cardiac, cerebrovascular, and renal events (MACCREs). The summed stress score (SSS), summed rest score, and summed difference score (SDS) were estimated with the standard 17-segment, 5-point scoring model. Left ventricular end-diastolic volume, end-systolic volume (ESV), and ejection fraction were measured using electrocardiogram-gated SPECT. During the first year of follow-up, 69 of 299 patients experienced MACCREs (CD, n = 7; non-fatal myocardial infarction, n = 3; hospitalization for heart failure, n = 13; cerebrovascular accident, n = 1; need for revascularization, n = 38; and renal failure, i.e., hemodialysis initiation, n = 7). ESV and SSS were associated with CDs (p < 0.05), and eGFR and SDS were associated with MACCREs (p < 0.05), in multivariate logistic analysis. Patients with high ESV and high SSS had a significantly higher CD rate during the first year than the other CKD patient subgroups (p < 0.05). Patients with low eGFR and high SDS had a significantly higher MACCRE rate than the other subgroups (p < 0.05). Myocardial perfusion SPECT can provide reliable prognostic markers for patients with CKD. (orig.)

    Full Text Available Background: Quality of life related to health is a reliable and necessary indicator for the analysis of the sanitary state in a community. It is also a data source to define strategies in health actions in a population. Objective: To describe the aspects related to quality of life in two- year survivors from cerebrovascular disease. Method: A retrospective and prospective, descriptive study of a serie of cases with quality of life assessment related to patient’s health two years after being discharged from hospital due to ictus. A simple random sampling was performed and applied to survivors. Quality of life scale for ECVI–38 ictus was used determining the most affected cerebral dominance by means of statistic techniques. Results: the quality of life assessment in ictus showed a general mean of 46.5. The spheres identified as more engaged were the feelings and the emotional one. Illness in several of the cerebral dominance was confirmed in the majority of survivors although the obtained measurements were not high. The level of recovering at two years of the beginning of the disease was little or none in 31 ill patients. Conclusions: Alterations in quality of life related to health are sequelae which in more or lesser degree suffer from the majority of the survivors to a neuroictus. These can be determined applying ECVI-38. It is necessary to take measures to minimize the deleterious effects and fulfill the objectives for survivors have a satisfactory quality of life.

    Full Text Available In Canada, as in other Western countries, much media and scholarly attention surrounding the “War on Terror” has focused on cases in which primarily Muslim citizens have been detained and charged under the anti-terror law passed hastily in 2001. However, little analysis has been conducted on how legislation and communicative strategies on terror have re-framed the domestic neo-liberal agenda, and, in so doing, fostered a militarized culture of surveillance and fear of the enemy inside its borders. This paper examines the Canadian government’s domestic politics of terror through its communication on the inter-related issues of crime, defence, security, and immigration that are propagated through the lens of the global War on Terror. Using parliamentary records, public documents and media stories, the paper suggests that, over time since it came to power in 2006, the government has invoked both the Muslim Other and a subtler, more generalized domestic enemy in order to capitalize on public concern and fear of terrorism to justify its neo-liberal legislative agenda and consolidate its power within the broader neo-liberal project. More than a decade after the events of 9/11, this case study and other research now exist on how the neo-liberal Canadian state uses fear and patriotism to achieve its domestic objectives through legislative and communicative strategies.

    Research on the association between ambient temperature and cerebrovascular morbidity is scarce in China. In this study, we applied mixed generalized additive model (MGAM) to daily counts of cerebrovascular disease of Shanghai residents aged 65 years or older from 2007-2011, stratified by gender. Weighted daily mean temperature up to lags of one week was smoothed by natural cubic spline, and was added into the model to assess both linear and nonlinear effects of temperature. We found that when the mean temperature increased by 1 °C, the male cases of cerebrovascular disease reduced by 0.95% (95% Confidence Interval (CI): 0.80%, 1.10%) or reduced by 0.34% (95% CI: -0.68, 1.36%) in conditions of temperature was below or above 27 °C. However, for every 1 °C increase in temperature, the female cases of cerebrovascular disease increased by 0.34% (95% CI: -0.26%, 0.94%) or decreased by 0.92% (95% CI: 0.72, 1.11%) in conditions of temperature was below or above 8 °C, respectively. Temperature and cerebrovascular morbidity is negatively associated in Shanghai. MGAM is recommended in assessing the association between environmental hazards and health outcomes in time series studies.

    Full Text Available Abstract Background The impact of long term residence on high altitude (HA on human brain has raised concern among researchers in recent years. This study investigated the cerebrovascular reactivity among native-born high altitude (HA residents as compared to native sea level (SL residents. The two groups were matched on the ancestral line, ages, gender ratios, and education levels. A visual cue guided maximum inspiration task with brief breath holding was performed by all the subjects while Blood-Oxygenation-Level-Dependent (BOLD functional Magnetic Resonance Imaging (fMRI data were acquired from them. Results Compared to SL controls, the HA group showed generally decreased cerebrovascular reactivity and longer delay in hemodynamic response. Clusters showing significant differences in the former aspect were located at the bilateral primary motor cortex, the right somatosensory association cortex, the right thalamus and the right caudate, the bilateral precuneus, the right cingulate gyrus and the right posterior cingulate cortex, as well as the left fusiform gyrus and the right lingual cortex; clusters showing significant differences in the latter aspect were located at the precuneus, the insula, the superior frontal and temporal gyrus, the somatosensory cortex (the postcentral gyrus and the cerebellar tonsil. Inspiratory reserve volume (IRV, which is an important aspect of pulmonary function, demonstrated significant correlation with the amount of BOLD signal change in multiple brain regions, particularly at the bilateral insula among the HA group. Conclusions Native-born HA residents generally showed reduced cerebrovascular reactivity as demonstrated in the hemodynamic response during a visual cue guided maximum inspiration task conducted with BOLD-fMRI. This effect was particularly manifested among brain regions that are typically involved in cerebral modulation of respiration.

    Background Risk knowledge and active role preferences are important for patient involvement in treatment decision-making and adherence. Although knowledge about stroke warning signs and risk factors has received considerable attention, objective knowledge on secondary prevention and further self-esteem subjective knowledge have rarely been studied. The aim of our study was to investigate knowledge and treatment decisional role preferences in cerebrovascular patients compared to controls. Methods We performed a survey on subjective and objective stroke risk knowledge and autonomy preferences in cerebrovascular patients from our stroke outpatient clinic (n=262) and from pedestrians on the street taken as controls during a “World Stroke Day” (n=274). The questionnaire includes measures for knowledge and decisional role preferences from previously published questionnaires and newly developed measures, for example, subjective knowledge, revealed on a visual analog scale. Results The overall stroke knowledge was low to moderate, with no differences between patients and controls. Knowledge about secondary prevention was particularly low. Only 10%–15% of participants correctly estimated the stroke absolute risk reduction potential of aspirin. The medical data interpretation competence was moderate in both groups. Age and basic mathematical and statistical understanding (numeracy) were the only independent predictors of objective stroke knowledge, whereas previous stroke had no impact on stroke knowledge. However, patients were thought to be better informed than controls. Approximately 60% of both patients and controls claimed to prefer a shared decision-making approach in treatment decisions. Conclusion The level of stroke risk knowledge in patients with cerebrovascular diseases was as low as in randomly selected pedestrians, although patients felt better informed. Both groups preferred involvement in treatment decision-making. We conclude that educational concepts

    The primary purpose of this Brain in Motion (BIM) sub-study was to determine the 6-month stability of resting blood flow velocity and cerebrovascular responsiveness to a euoxic hypercapnic challenge in a group of physically inactive community dwelling men and men aged ≥55 yrs (range 55-92 yrs). At baseline and 6 months later 88 women (65±6 yr) and 78 men (67±7 yr) completed a hypercapnic challenge (step changes from resting end-tidal PCO2 ((PETCO2) to +1, +5 and +8 mmHg above rest) while cerebral blood flow velocity was assessed using transcranial Doppler ultrasound. Peak velocity of the middle cerebral artery (MCAv) was increased (p0.05) when MCAv was normalized to PETCO2. During hypercapnia, MCAv tended to be increased at follow-up, but this finding was absent when MCAv/PETCO2 was compared across time. Cerebrovascular reactivity (i.e., ΔMCAv/ΔPETCO2) was similar (p>0.05) between testing occasions regardless of the approach taken (i.e., considering only the lower step [from +1 to +5 mmHg]; the upper step [+5 to +8 mmHg]; or the complete test taken together). In conclusion, this study has shown that cerebral blood flow and cerebrovascular responsiveness to acute euoxic hypercapnia are stable in older, healthy adults over a 6-month period. Modest changes in MCAv over time must be viewed in the context of underlying differences in PETCO2, an important finding with implications for future studies considering cerebral blood flow velocity.

    Full Text Available Abstract Background: Cerebrovascular and hypertensive diseases are among the main causes of death worldwide. However, there are limited data about the trends of these diseases over the years. Objective: To evaluate the temporal trends in mortality rates and proportional mortality from cerebrovascular and hypertensive diseases according to sex and age in Brazil between 1980 and 2012. Methods: We evaluated the underlying causes of death between 1980 and 2012 in both sexes and by age groups for circulatory diseases (CD, cerebrovascular diseases (CBVD, and hypertensive diseases (HD. We also evaluated death due to all causes (AC, external causes (EC, and ill-defined causes of death (IDCD. Data on deaths and population were obtained from the Department of Information Technology of the Unified Health System (Departamento de Informática do Sistema Único de Saúde, DATASUS/MS. We estimated crude and standardized annual mortality rates per 100,000 inhabitants and percentages of proportional mortality rates. Results: With the exception of EC, the mortality rates per 100,000 inhabitants of all other diseases increased with age. The proportional mortality of CD, CBVD, and HD increased up to the age range of 60-69 years in men and 70-79 years in women, and reached a plateau in both sexes after that. The standardized rates of CD and CBVD declined in both sexes. However, the HD rates showed the opposite trend and increased mildly during the study period. Conclusion: Despite the decline in standardized mortality rates due to CD and CBVD, there was an increase in deaths due to HD, which could be related to factors associated with the completion of the death certificates, decline in IDCD rates, and increase in the prevalence of hypertension.

  17. Clinical significance of the dynamic changes of serum IGF-1 levels in patients with acute cerebro-vascular accident

    International Nuclear Information System (INIS)

    Objective: To investigate the dynamic changes of serum insulin-like growth factor-1 (IGF-1) levels in patients with acute cerebrovascular accident. Methods: Serum IGF-1 levels were determined with RIA in 40 patients with cerebral infarction, 20 patients with lacunar infarcts and 40 patients with cerebral haemorrhage within 3days after onset and on d14 as well as in 30 controls. Results: The serum IGF-1 levels in patients with cerebral vascular accidents were significantly lower than those in controls (P 0.05). Conclusion: Serum levels of IGF-1 dropped markedly during the acute stage after cerebrovascular accident and the magnitude might reflect the severity of the event, IGF-1 might be capable of crossing the blood-brain barrier after cerebrovascular accident and providing some protection against nerve injury, this fact might be of potential clinical applicability.

    We studied the relationship between cortical grey matter flow (CBF) and age, cerebrovascular risk factors and the severity of subcortical hypersignals (HS, hyperintensity score in MRI) in 47 asymptomatic subjects with cerebrovascular risk factors. Multiple regression analysis revealed that HS was most strongly related to CBF, and that hematocrit, age and evidence of ischemic change detected in the electrocardiogram also appeared to be independent determinants of CBF. Both the severity and location of hypersignals were correlated with CBF. The most significant negative correlation observed was that between CBF and HS in the basal ganglia-thalamic region, where the degree of signal abnormality was modest. Decreased CBF in asymptomatic subjects with cerebrovascular risk factors may be related to microcirculatory disturbance associated with elevated hematocrit and an increase in the number of risk factors, and functional suppression of cerebral cortex due to the neuronal disconnection associated with subcortical lesions. In addition, impaired cerebral circulation may be related to MRI signal abnormalities. (author).

Para ello, se analizan las distintas estrategias que se desplegaron para prolongar en el tiempo el apoyo dispensado al golpe militar de 1973 por el llamado Poder Gremial, compuesto, entre otros, por una parte significativa del movimiento sindical que se opuso a Salvador Allende, examinando, también, las razones del fracaso de estas estrategias de cooptación del movimiento sindical, confirmado con el triunfo de las políticas neoliberales en el ámbito laboral. La hipótesis que atraviesa este trabajo sostiene que el diseño del régimen militar no fue capaz de romper con la histórica cultura sindical de la organización de trabajadores en Chile.This article deals with the attempts of the military regime lead by the general Augusto Pinochet to penetrate workers organizations between the times of the coup d'etat and the installation of the Labor plan designed by José Pinera. The article analyzes the various strategies used in order to prolong in time, the support that the regime had since the coup of 1973 from the so-called Poder Gremial, composed amongst others, by a significant faction of the labor movement who opposed Salvador Allende. Also examined are the reasons behind the failure of these strategies to co-opt the labor movement that were confirmed by the triumph of neo-liberal labor policies. The underlying hypothesis argues that the military regimes plan was not capable of breaking through the historic tradition of labor unions among Chilean workers.

  3. Relationship between oxygen free radicals, cytokines, cortisol and stress complications in patients with acute cerebrovascular disease

    International Nuclear Information System (INIS)

    Objective: To investigate the relationship between oxygen free radicals, cytokines, cortisol and stress complications in patients with acute cerebrovascular disease (ACVD). Methods: Serum levels of superoxide dismutases (SOD), malonaldehyde (MDA) (with biochemistry) interleukin-6 (IL-6), tumor necrosis factor (TNF-α) and cortisol (with RIA) were measured in 32 patients with acute cerebrovascular disease (ACVD) plus stress complications and 48 patients without stress complications as well as 36 controls. Results: Serum SOD contents in non-stressed group were higher than those in stressed group (P<0.05) but lower than those of the controls (P<0.05). However the levels of MDA, IL-6, TNF-α and cortisol were highest in the stressed group and lowest in the controls (all P<0.05). Conclusion: Oxygen free radicals, IL-6, TNF-α and cortisol were involved in stress complications in patients with ACVD. Monitoring the levels of serum SOD, MDA, IL-6, TNF-α and cortisol could be useful for predicting stress complications and evaluating the therapeutic effect. (authors)

    Cerebrovascular endothelial cell dysfunction resulting in imbalance of cerebral blood flow contributes to the onset of psychiatric disorders such as depression, schizophrenia and bipolar disorder. Although decrease in Na(+), K(+)-ATPase activity has been reported in the patients with schizophrenia and bipolar disorder, the contribution of Na(+), K(+)-ATPase to endothelial cell dysfunction remains poorly understood. Here, by using rat neonatal prefrontal cortex slice cultures, we demonstrated that pharmacological inhibition of Na(+), K(+)-ATPase by ouabain induced endothelial cell injury. Treatment with ouabain significantly decreased immunoreactive area of rat endothelial cell antigen-1 (RECA-1), a marker of endothelial cells, in a time-dependent manner. Ouabain also decreased Bcl-2/Bax ratio and phosphorylation level of glycogen synthase kinase 3β (GSK3β) (Ser9), which were prevented by lithium carbonate. On the other hand, ouabain-induced endothelial cell injury was exacerbated by concomitant treatment with LY294002, an inhibitor of phosphoinositide 3- (PI3-) kinase. We also found that xestospongin C, an inhibitor of inositol triphosphate (IP3) receptor, but not SEA0400, an inhibitor of Na(+), Ca(2+) exchanger (NCX), protected endothelial cells from cytotoxicity of ouabain. These results suggest that cerebrovascular endothelial cell degeneration induced by Na(+), K(+)-ATPase inhibition resulting in Ca(2+) release from endoplasmic reticulum (ER) and activation of GSK3β signaling underlies pathogenesis of these psychiatric disorders.

  5. Evaluation of the cerebrovascular pressure reactivity index using non-invasive finapres arterial blood pressure

    International Nuclear Information System (INIS)

    A pressure reactivity index (PRx) can be assessed in patients with continuous monitoring of arterial blood pressure (ABP) and intracranial pressure (ICP) as a moving correlation coefficient between slow fluctuations of these two signals within a low frequency bandwidth. The study aimed to investigate whether the invasive ABP monitoring can be replaced with non-invasive measurement of ABP using a Finapres plethysmograph (fABP) to calculate the fPRx. There is a well-defined group of patients, suffering from hydrocephalus and undergoing CSF pressure monitoring, which may benefit from such a measurement. 41 simultaneous day-by-day monitoring of ICP, ABP and fABP were performed for about 30 min in 10 head injury patients. A Bland–Altman assessment for agreement was used to compare PRx and fPRx calculations. Performance metrics and the McNemary test were used to determine whether fPRx is sensitive enough to distinguish between functioning and disturbed cerebrovascular pressure reactivity. The fPRx correlated with PRx (RSpearman = 0.92, p < 0.001; bias = −0.04; lower and upper limits of agreement: −0.26 and 0.17, respectively). The fPRx distinguished between active and passive reactivity in more than 89% cases. The fPRx can be used with care for assessment of cerebrovascular reactivity in patients for whom invasive ABP measurement is not feasible. The fPRx is sensitive enough to distinguish between functional and deranged reactivity

    HIV protease inhibitors are key components of HIV antiretroviral therapies, which are fundamental in the treatment of HIV infection. However, the protease inhibitors are well-known to induce metabolic dysfunction which can in turn escalate the complications of HIV, including HIV associated neurocognitive disorders. As experimental and epidemiological data support a therapeutic role for adiponectin in both metabolic and neurologic homeostasis, this study was designed to determine if increased adiponectin could prevent the detrimental effects of protease inhibitors in mice. Adult male wild type (WT) and adiponectin-overexpressing (ADTg) mice were thus subjected to a 4-week regimen of lopinavir/ritonavir, followed by comprehensive metabolic, neurobehavioral, and neurochemical analyses. Data show that lopinavir/ritonavir-induced lipodystrophy, hypoadiponectinemia, hyperglycemia, hyperinsulinemia, and hypertriglyceridemia were attenuated in ADTg mice. Furthermore, cognitive function and blood-brain barrier integrity were preserved, while loss of cerebrovascular markers and white matter injury were prevented in ADTg mice. Finally, lopinavir/ritonavir caused significant increases in expression of markers of brain inflammation and decreases in synaptic markers in WT, but not in ADTg mice. Collectively, these data reinforce the pathophysiologic link from metabolic dysfunction to loss of cerebrovascular and cognitive homeostasis; and suggest that preservation and/or replacement of adiponectin could prevent these key aspects of HIV protease inhibitor-induced toxicity in clinical settings.

  8. The complex contribution of NOS interneurons in the physiology of cerebrovascular regulation

    Full Text Available Following the discovery of the vasorelaxant properties of nitric oxide (NO by Furchgott and Ignarro, the finding by Bredt and coll. of a constitutively expressed NO synthase in neurons (nNOS led to the presumption that neuronal NO may control cerebrovascular functions. Consequently, numerous studies have sought to determine whether neuraly-derived NO is involved in the regulation of cerebral blood flow. Anatomically, axons, dendrites or somata of NO neurons have been found to contact the basement membrane of blood vessels or perivascular astrocytes in all segments of the cortical microcirculation. Functionally, various experimental approaches support a role of neuronal NO in the maintenance of resting cerebral blood flow as well as in the vascular response to neuronal activity. Since decades, it has been assumed that neuronal NO simply diffuses to the local blood vessels and produce vasodilation through a cGMP-PKG dependent mechanism. However, NO is not the sole mediator of vasodilation in the cerebral microcirculation and is known to interact with a myriad of signaling pathways also involved in vascular control. In addition, cerebrovascular regulation is the result of a complex orchestration between all components of the neurovascular unit (i.e. neuronal, glial and vascular cells also known to produce NO. In this review article, the role of NO interneuron in the regulation of cortical microcirculation will be discussed in the context of the neurovascular unit.

    2015-04-01

    Hypertension and hypertension associated cerebrovascular and cardiovascular diseases are on a rise. At-least 970 million people in the world and Seventy percent of the American adults are affected by high blood pressure, also known as hypertension. Even though blood pressure monitoring systems are readily available, the number of people being affected has been increasing. Most of the blood pressure monitoring systems require cumbersome approaches. Even the noninvasive techniques have not lowered the number of people affected nor did at-least increase the user base of these systems. Uncontrolled or untreated hypertension may lead to various cerebrovascular disorders including stroke, hypertensive crisis, lacunar infarcts intracerebral damage, microaneurysm, and cardiovascular disorders including heart failure, myocardial infraction, and ischemic heart disease. Hypertension is rated as the one of the most important causes of premature death in spite of the technical advances in biomedical technology. This paper briefs a review of the widely adopted blood pressure monitoring methods, research techniques, and finally, proposes a concept of implementing nanosensors and wireless communication for real time non-invasive blood pressure monitoring.

    Magnetic resonance imaging (MRI) study was performed in 32 patients with recent lacunar stroke. T2-weighted images showed ischemic lesions more clearly than T1-weighted images. Sixty-six percent of 32 patients had periventricular lesions. Eighty-four percent had subcortical white matter lesions. Sixty-nine percent had lesions in basal ganglia. Twenty-eight percent had lesions in brainstem. Periventricular lesions were revealed symmetrically. On the other hand, lesions in other areas were not detected symmetrically. Severe periventricular lesions on MRI were similar to those of Binswanger's disease. Patients with severe periventricular lesions had often hypertension. Moreover, two of them had dementia. Twenty-three patients with transient ischemic attack had less remarkable lesions than patients with lacunar stroke. Thirty-seven patients with a history of cerebrovascular risk factors (hypertension, diabetes mellitus) had severer lesions compared with normal controls. Sixty-one percent of controls, who had no cerebrovascular symptoms and signs, had MRI lesions. These results suggest that MRI is useful for detection of cerebral ischemic lesions with no associated clinical symptoms or signs. (author).

    2016-01-01

    Full Text Available The efficacy of naftidrofuryl in treating cerebrovascular diseases is analyzed on the basis of a review of the Russian and foreign literature. Naftidrofuryl is a seroton 5-HT2 receptor antagonist and acts on brain energy metabolism mainly during hypoxia or ischemia. The results of preclinical studies proving the antispasmodic and neuroprotective properties of the drug and its capacity to normalize microcirculation in hypoxia are briefly considered. Experimental findings served as a basis for further studies of the efficacy of naftidrofuryl in patients with stroke, chronic cerebral ischemia, or vascular dementia. The use of naftidrofuryl (dusopharm was demonstrated to statistically significantly enhance the efficiency of rehabilitation in post-stroke patients and to be followed by significant psychoemotional improvement. According to a Cochrane review, the naftidrofuryl-treated patients with vascular dementia showed a tendency towards better executive and cognitive functions, behavior, and mood. The drug was noted to have a positive effect on the health of patients with chronic cerebral ischemia.The authors provide the data of their trial of naftidrofuryl used in patients with dyscirculatory encephalopathy, which have confirmed its efficacy in this category of patients. The data available in the literature suggest that oral naftidrofuryl has a good tolerability and safety profile in patients with cerebrovascular diseases.

  13. Neuroimaging assessment of cerebrovascular reactivity in concussion: current concepts, methodological considerations and review of the literature

    Full Text Available Concussion is a form of traumatic brain injury (TBI that presents with a wide spectrum of subjective symptoms and few objective clinical findings. Emerging research suggests that one of the processes that may contribute to concussion pathophysiology is dysregulation of cerebral blood flow (CBF leading to a mismatch between CBF delivery and the metabolic needs of the injured brain. Cerebrovascular reactivity (CVR is defined as the change in CBF in response to a measured vasoactive stimulus. Several magnetic resonance imaging (MRI techniques can be used as a surrogate measure of CBF in clinical and laboratory studies. In order to provide an accurate assessment of CVR, these sequences must be combined with a reliable, reproducible vasoactive stimulus that can manipulate CBF. Although CVR imaging currently plays a crucial role in the diagnosis and management of many cerebrovascular diseases, only recently have studies begun to apply this assessment tool in patients with concussion. In order to evaluate the quality, reliability and relevance of CVR studies in concussion, it is important that clinicians and researchers have a strong foundational understanding of the role of cerebral blood flow regulation in health, concussion and more severe forms of TBI, and an awareness of the advantages and limitations of currently available CVR measurement techniques. Accordingly, in this review we 1 discuss the role of CVR in TBI and concussion; 2 examine methodological considerations for MRI-based measurement of CVR; and 3 provide an overview of published CVR studies in concussion patients.

  14. Study on the relationship between serum leptin level and ischemic cerebrovascular disease (ICVD)

    International Nuclear Information System (INIS)

    Objective: To investigate the inter-relationship among serum leptin insulin resistance and blood lipids, and to explore the role of leptin in the pathogenesis of ischemic cerebrovascular diseases (ICVD). Methods: Levels of serum leptin, insulin and blood lipids were determined with RIA in 131 patients with different types of ICVD and 36 controls. Results: The levels of serum leptin in ICVD patients were significantly higher than those in the controls (P<0.01). Changes of blood lipids and insulin paralleled those of leptin (cxcept with HDL-C). The serum leptin were positively correlated to cholesterol, TG and insulin levels (r=0.45, P<0.05; r=0.31, P<0.05, r=0.55, P<0.01), but negatively correlated to HDL-C (r=-0.88, P<0.05). Conclusion: The high expression of leptin in ICVD patients is associated with high lipid and insulin levels. The close relationship among them indicates that high leptin levels play an important role in the pathogenesis of metabolic syndrome as well as atheromatous cerebrovascular diseases. (authors)

    Cerebrovascular diseases in patients between 15 and 40 years old are not a frequent subject in Latin-American literature, especially when focusing on neuropathology. We analyzed 47 brains from necropsies performed from 1987 to 1997 and selected on a basis of age and the presence of vascular pathology. From the 47 analyzed brains, 26 belonged to females (55.3%). When distributed among age groups, 12.8% (n=6) affected patients from 15 to 20 yo, 51,1% (n=24) from 21 to 30 yo, 36,2% (n=17) from 31 to 40 yo. The underlying diseases were: cardiac and haemathologic (19.2%), pregnancy complications (12.76%), infections, diseases of blood vessels and neurological (10.1% each) amongst others. The neuropathological abnormalities included cerebral and/or cerebellar herniation (16%), cerebral edema (13.8%), subarachnoid hemorrhage (10%), recent cerebral infarction (9%), intraparenchymatous hemorrhage (8.14%), hypoxic-ischemic encephalopathy (3%) and other events such as Sneddon syndrome and Lupus vasculitis. These findings express that the cerebrovascular phenomena in this age group are unique and closely related with the underlying disease. PMID:11733838

  16. Positron emission tomographic studies using C-11-glucose in normal aging and cerebrovascular dementia

    International Nuclear Information System (INIS)

    Seven normal volunteers and 11 patients with cerebrovascular dementia were studied about the relations between effect of aging, severity of dementia, cerebral glucose metabolism and metabolic response to verbal stimuli by positron emission tomography (PET) using C-11-glucose. Regional distribution of glycogenic metabolites (RDGM: mg/100 g brain), which was a semi-quantitation of the pool of glycogenic metabolites mainly amino acids, were calculated. The RDGM values in elder normal subjects were significantly low compared with young normal subjects in frontal cortex (p < 0.05). The decline in frontal cortex metabolism could have been caused by the morphological changes in the course of aging. In temporal cortex, there was no significance between two groups. RDGM increased significantly respond to the verbal stimuli in frontal and temporal cortex both young and elder normal subjects. The RDGM values in vascular dementias were significantly low (p < 0.001) compared with elder normal subjects' in frontal and temporal cortex. Significant difference existed between mild and severe dementia in frontal cortex (p < 0.05). However, there was no significance between mild and severe dementias in temporal cortex. In mild dementias, RDGM increased significantly respond to the verbal stimuli in frontal and temporal cortex. In severe dementias, metabolic response to the verbal stimuli was less or lacking. Our results suggest that the cerebral metabolic functional reserve and the ability of the cerebral cortex to function respond to psychophysiologic stimulation are preserved in young and elder normal subjects and mild cerebrovascular dementias.

    Full Text Available Objetivo: Conduzir uma revisão sistemática sobre resiliência psicológica e/ou hardiness em militares, explorando seus aspectos psicossociais, neurobiológicos, preditores e promotores. Métodos: Utilizaram-se as bases de dados PubMed/MedLine, ISI/Web of Science e PsycINFO, incluindo artigos empíricos publicados nas línguas inglesa, portuguesa e espanhola até maio de 2012. Os seguintes termos foram utilizados: “militar*”, “Army”, “war”, “veteran*”, “resilien*” e “hardiness”. Resultados: Foram incluídos 32 estudos selecionados a partir de 1.205 artigos. O foco da maioria das pesquisas recai sobre a correlação resiliência/hardiness e aspectos psicossociais. Confirmou-se o papel protetivo da resiliência/hardiness quanto ao transtorno de estresse pós-traumático (TEPT, assim como a associação direta entre resiliência e saúde. Neuropeptídeo Y (NPY e deidroepiandrosterona (DHEA foram os biomarcadores mais estudados. Os níveis de NPY no plasma podem representar um correlato biológico de resiliência ou recuperação dos efeitos adversos do estresse. Somente dois estudos abordaram fatores preditores de resiliência em amostras militares, sugerindo ser a exposição a situações adversas, o apoio social e o gênero fatores considerados preditores desse construto. Apenas um estudo avaliou a eficiência de intervenção para fortalecer a resiliência. Conclusão: Apesar da crucial relevância da resiliência, há poucos estudos em amostras militares. Estudos neurobiológicos como os do NPY são promissores. A ausência de ensaio randomizado controlado avaliando eficácia de intervenções promotoras da resiliência demonstra como esse construto vem sendo negligenciado nessa profissão de risco, constituindo área prioritária para foco de estudos futuros.

    Full Text Available Cerebrovascular diseases constitute a health problem worldwide and have the tendency to grow up. Chronic diseases sometimes are considered transmissible diseases at a level of risk factors. The alimentary habits and the levels of physical activity at present are risk behaviors which are spread all over the world passing from one population to another as an infectious disease with incidence in the morbidity profiles worldwide. While age and sex as well as genetic vulnerability are no modifiable elements, great part of the risks associated to age and sex can be reduced. In such risks, behavior factors (alimentary habits, physical inactivity, smoking habit and alcoholism, biological factors (dyslipidemia, hypertension, overweight, and hyperinsulinemia and finally the social factors which cover a complex combination of socio-economic, cultural parameters, and other elements of the environment that interact among them. This work covers risk factors and the behavior to be followed for its modification.

  14. The cerebrovascular structure and brain tissue volume: a comparative study between beagle dogs and mongrel dogs

    International Nuclear Information System (INIS)

    Objective: To compare the differences of cerebrovascular structure and brain tissue volume between beagle and mongrel dogs by using angiography and MR scanning. Methods: A total of 40 dogs, including 20 beagle dogs (beagle group) and 20 mongrel dogs (mongrel group), were enrolled in this study. Under general anesthesia, all dogs were examined with cerebral angiography and MR scanning. The cerebrovascular structure was evaluated with angiography via selective catheterization of aortic arch, bilateral external cerebral arteries (ECA), maxillary arteries, internal cerebral arteries (ICA) and vertebral arteries separately. The diameters of the ICA, middle cerebral artery (MCA), rostral cerebral artery (RCA), the anastomosis channel ICA and ECA, and basilar artery (BA) were measured at the similar point of each dog. Meanwhile the volumes of the brain tissue were calculated in coronal T2 view of MR scanning. The statistical analysis was performed among the weight of dogs, the diameter of arteries and the volume of brain tissue. The differences in the diameters and brain tissue volume were compared between the two groups. Results: No obvious variations in the cerebrovascular structure and brain tissue volume were found in these dogs. One mongrel dog was excluded from this study because of the severe stenosis of ICA. The mean weight of 20 beagle dogs and 19 mongrel dogs was (12.81±1.29) kg and (12.85±1.12) kg, respectively. The diameters of the ICA, MCA, RCA, the anastomosis channel between ICA and ECA and BA in beagle group were (1.26±0.07) mm, (0.90±0.05) mm, (0.58±0.07) mm, (0.55±0.07) mm and (0.95±0.06) mm, respectively. These parameters in mongrel group were (1.27±0.07) mm, (0.92±0.05) mm, (0.59±0.06) mm, (0.67±0.07) mm and (0.94±0.05) mm, respectively. The volume of brain in two groups was (76232.33±5018.51) mm3 and (71863.96±4626.87) mm3, respectively. There were no obvious correlation among the body weight, the cerebrovascular diameters and brain

  19. Ultra-sensitive molecular MRI of cerebrovascular cell activation enables early detection of chronic central nervous system disorders

    International Nuclear Information System (INIS)

    Since endothelial cells can be targeted by large contrast-carrying particles, molecular imaging of cerebrovascular cell activation is highly promising to evaluate the underlying inflammation of the central nervous system (CNS). In this study, we aimed to demonstrate that molecular magnetic resonance imaging (MRI) of cerebrovascular cell activation can reveal CNS disorders in the absence of visible lesions and symptoms. To this aim, we optimized contrast carrying particles targeting vascular cell adhesion molecule-1 and MRI protocols through both in vitro and in vivo experiments. Although, pre-contrast MRI images failed to reveal the ongoing pathology, contrast-enhanced MRI revealed hypoperfusion-triggered CNS injury in vascular dementia, unmasked amyloid-induced cerebrovascular activation in Alzheimer's disease and allowed monitoring of disease activity during experimental autoimmune encephalomyelitis. Moreover, contrast-enhanced MRI revealed the cerebrovascular cell activation associated with known risk factors of CNS disorders such as peripheral inflammation, ethanol consumption, hyperglycemia and aging. By providing a dramatically higher sensitivity than previously reported methods and molecular contrast agents, the technology described in the present study opens new avenues of investigation in the field of neuro-inflammation.

    2007-07-01

    Full Text Available The purpose of this bibliographical review is to show the role of the family in the application of care of a patient suffering from a cerebrovascular accident (CVA. CVA's are, second to arthritis, one of the most impairing illnesses in terms of ability that creates the need for training the patient on a new basis and giving the family information on new roles. One of the dimensions of holistic family care is the increased support the patient receives from family care givers. Studies and clinical research both show that informing families on care giver roles is inadequate or non‐existent. Adequate training of nurses to prepare care givers via specialized programs stimulates the family to respond to the new challenge and take on roles that are multidimensional and complicated. It is important that family care givers of people with CVA's are given new information and taught new skills in order for these patients to maximize their own self‐care potential. CVA patients, following the acute phase of their illness and rehabilitation in specialized centers are nursed at home, mainly by their families with the help of healthcare services. Usually, the responsibilities the family takes on are mainly those of self‐care needs of the patient and his motivation, so that he will organize and carry out basic life activities via learning new ways to face everyday life, always within his impaired abilities. Care guidance is a most important nursing intervention so that activities of daily living problems can be addressed. The interventions are tailored according to the care givers' educational level and the patients' needs. CONCLUSIONS The most important findings of the study are: Patients with cerebrovascular accidents have impaired ability concerning mobility, communication and socialization and need special attention and education in order to improve daily life activities. The education of hemiplegic patients with informative intervention, awareness and

  1. Alzheimer's disease in late-life dementia: a minor toxic consequence of devastating cerebrovascular dysfunction.

    2008-01-01

    Alzheimer's disease (AD) is thought to be the most common cause of late-life dementia. But pure AD is infrequent whereas AD pathology is often insufficient to explain dementia in the elderly. Conversely, cerebrovascular disease is omnipresent and the crucial role of microvascular alterations increasingly recognized in late dementia or "Alzheimer syndrome". Pathomechanisms of vascular cognitive impairment are still debated but recent data indicate that the initial concept of chronic low grade cerebral hypoxia should not have been abandoned. Thus, it is proposed that windkessel dysfunction is the missing link between vascular and craniospinal senescence on the one hand, and chronic low grade cerebral hypoxia, "senile brain degeneration" and "Alzheimer syndrome" on the other hand. An age-related decrease in the buffering capacity of both the vessels and the craniospinal cavity favours cerebral hypoxia; due to increased capillary pulsatility with disturbances in capillary exchanges or due to a marked reduction in craniospinal compliance with a mechanical reduction in cerebral arterial inflow. "Invisible" windkessel dysfunction, most often related to "hardening of the arteries" may be the most frequent pathomechanism of late-onset dementia whereas associated mild or moderate AD may be merely a toxic manifestation of a primarily hypoxic disease. Structural patterns of arteriosclerotic dementia fit well with an underlying arterial windkessel dysfunction: with secondary mechanical damage to the cerebral small vessels and the brain and predominantly deep hypoxia. The clinical significance of leukoaraïosis, small foci of necrosis, ventricular dilatation, hippocampal and cortical atrophy is in good agreement with their value as indirect markers of windkessel dysfunction. An age-related "invisible" reduction in craniospinal compliance may also contribute to the associations between heart failure, arterial hypotension and cognitive impairment in the elderly and to the high

    Cerebrovascular disease is one of the leading causes of death, and approximately 50% of survivors have a residual neurologic deficit and greater than 25% require chronic care. Cerebrovascular reserve capacity (CVRC) describes how far cerebral perfusion can increase from a baseline value after stimulation. High blood pressure is the most important independent risk factor for stroke and other vascular diseases. The incidence of stroke in the hypertensive is six times higher than in the patient with normal blood pressure. CVRC in the hypertensive was even lower than in control patients. MR perfusion weighted imaging (MR PWI) with the well-established acetazolamide (ACZ) stimulation test has been used for assessing brain function. The aim of this work is to assess the cerebrovascular reserve capacity by MR PWI with "ACZ" tolerance test in spontaneous hypertensive rat (SHR) and to identify its value in evaluating the CVRC. Experimental animal including 3 groups: Wistar-Kyoto rats (WKY) (12-week-old) as control group, SHR (12-week-old and 20-week-old) as experimental group. MR PWI was performed respectively before and after acetazolamide administrated orally in 3 groups on a clinical 1.5 Tesla GE Signa MR fx/i whole-body MR system. The ROI was chosen in the bilateral frontal lobe to measure the value of rCBV, rCBF and MTT. The results showed that before ACZ-test, there was statistic differences between the WKY and SHR(12-week-old), and between SHR(12-week-old) and SHR(20-week-old) in the values of rCBV and rCBF (P>0.05), and after ACZ-test, there were statistic differences between WKY and SHR (20-week-old), and between SHR(12-week-old) and SHR(20-week-old) in the rCBV value (Pstress test" can provide more qualitative and half-quantitative information on the cerebral perfusion to evaluate the CVRC in SHR.

  3. Beneficial effects of estrogen in a mouse model of cerebrovascular insufficiency.

    Directory of Open Access Journals (Sweden)

    Naohito Kitamura

    Full Text Available BACKGROUND: The M(5 muscarinic acetylcholine receptor is known to play a crucial role in mediating acetylcholine dependent dilation of cerebral blood vessels. Previously, we reported that male M(5 muscarinic acetylcholine knockout mice (M5R(-/- mice suffer from a constitutive constriction of cerebral arteries, reduced cerebral blood flow, dendritic atrophy, and short-term memory loss, without necrosis and/or inflammation in the brain. METHODOLOGY/PRINCIPAL FINDINGS: We employed the Magnetic Resonance Angiography to study the area of the basilar artery in male and female M5R(-/- mice. Here we show that female M5R(-/- mice did not show the reduction in vascular area observed in male M5R(-/- mice. However, ovariectomized female M5R(-/- mice displayed phenotypic changes similar to male M5R(-/- mice, strongly suggesting that estrogen plays a key role in the observed gender differences. We found that 17beta-estradiol (E2 induced nitric oxide release and ERK activation in a conditional immortalized mouse brain cerebrovascular endothelial cell line. Agonists of ERalpha, ERbeta, and GPR30 promoted ERK activation in this cell line. Moreover, in vivo magnetic resonance imaging studies showed that the cross section of the basilar artery was restored to normal in male M5R(-/- mice treated with E2. Treatment with E2 also improved the performance of male M5R(-/- mice in a cognitive test and reduced the atrophy of neural dendrites in the cerebral cortex and hippocampus. M5R(-/- mice also showed astrocyte swelling in cortex and hippocampus using the three-dimensional reconstruction of electron microscope images. This phenotype was reversed by E2 treatment, similar to the observed deficits in dendrite morphology and the number of synapses. CONCLUSIONS/SIGNIFICANCE: Our findings indicate that M5R(-/- mice represent an excellent novel model system to study the beneficial effects of estrogen on cerebrovascular function and cognition. E2 may offer new therapeutic

    Full Text Available Este artigo propõe uma periodização inédita para analisar o processo de construção da memória do regime militar brasileiro. Partindo do princípio que a memória social e a experiência histórica de uma dada sociedade estão conectadas, procuramos analisar a construção de uma “memória mutável” sobre o regime desde os anos 1970 até a primeira década do século XXI. Nossa hipótese central aponta para a existência de uma memória hegemônica, crítica ao regime militar, construída na confluência de setores liberais (críticos dos aspectos autoritários do regime a partir de meados dos anos 1970 com setores das esquerdas, notadamente a esquerda ligada ao Partido Comunista Brasileiro (PCB.

    This paper argues for the continued significance of the text as a source and focus in critical geopolitical inquiry. It establishes the utility of the military memoir in explorations of popular contemporary geopolitical imaginaries, and considers the memoir as a vector of militarism. The paper examines the memoirs written by military personnel about service in Afghanistan with the British armed forces, specifically about deployments to Helmand province between 2006 and 2012. The paper explores how Afghanistan is scripted through these texts, focussing on the explanations for deployment articulated by their authors, on the representations they contain and promote about other combatants and about civilian non-combatants, and the constitution and expression of danger in the spaces and places of military action which these texts construct and convey. The paper then turns to consider how a reading of the military memoir with reference to the genre of testimonio might extend and inform our understanding and use of these texts as a source for exploring popular geopolitics and militarism.

  8. The Sarcoglycan complex is expressed in the cerebrovascular system and is specifically regulated by astroglial Cx30 channels

    Full Text Available Astrocytes, the most prominent glial cell type in the brain, send specialized processes called endfeet, around blood vessels and express a large molecular repertoire regulating the cerebrovascular system physiology. One of the most striking properties of astrocyte endfeet is their enrichment in gap junction protein Connexin 43 and 30 (Cx43 and Cx30 allowing in particular for direct intercellular trafficking of ions and small signaling molecules through perivascular astroglial networks. In this study, we addressed the specific role of Cx30 at the gliovascular interface. Using an inactivation mouse model for Cx30 (Cx30Δ/Δ, we showed that absence of Cx30 does not affect blood-brain barrier (BBB organization and permeability. However, it results in the cerebrovascular fraction, in a strong upregulation of Sgcg encoding γ-Sarcoglycan (SG, a member of the Dystrophin-associated protein complex (DAPC connecting cytoskeleton and the extracellular matrix. The same molecular event occurs in Cx30T5M/T5M mutated mice, where Cx30 channels are closed, demonstrating that Sgcg regulation relied on Cx30 channel functions. We further characterized the expression of other Sarcoglycan complex (SGC molecules in the cerebrovascular system and showed the presence of α-, β-, δ-, γ-, ε- and ζ- SG, as well as Sarcospan. Their expression was however not modified in Cx30Δ/Δ. These results suggest that a full SGC might be present in the cerebrovascular system, and that expression of one of its member, γ-Sarcoglycan, depends on Cx30 channels. As described in skeletal muscles, the SGC may contribute to membrane stabilization and signal transduction in the cerebrovascular system, which may therefore be regulated by Cx30 channel-mediated functions.

    2011-01-01

    The study of reactive oxygen species (ROS) and oxidative stress remains a very active area of biological research particularly in relation to cellular signaling and the role of ROS in disease. In the cerebral circulation, oxidative stress occurs in diverse forms of disease and with aging. Within the vessel wall, ROS produce complex structural and functional changes that have broad implications for regulation of cerebral perfusion and permeability of the blood–brain barrier. These oxidative stress-induced changes are thought to contribute to the progression of cerebrovascular disease. Here, we highlight recent findings in relation to oxidative stress in the cerebral vasculature, with an emphasis on the emerging role for NADPH oxidases as a source of ROS and the role of ROS in models of disease.

    Full Text Available There has been a growing interest in vascular impairment associated with Alzheimer’s disease (AD. This interest was stimulated by the findings of higher incidence of vascular risk factors in AD. Signs of vascular impairment were investigated notably in the field of imaging methods. Our aim was to explore ultrasonographic studies of extra- and intracranial vessels in patients with AD and mild cognitive impairment (MCI and define implications for diagnosis, treatment and prevention of the disease. The most frequently studied parameters with extracranial ultrasound are intima-media thickness in common carotid artery, carotid atherosclerosis, and total cerebral blood flow. The transcranial ultrasound concentrates mostly on flow velocities, pulsatility indices, cerebrovascular reserve capacity, cerebral microembolization. Studies suggest there is morphological and functional impairment of cerebral circulation in AD compared to healthy subjects. Ultrasound as a non-invasive method could be potentially useful in identifying individuals in a higher risk of progression of cognitive decline.

  13. Modeling Cerebrovascular Pathophysiology in Amyloid-β Metabolism using Neural-Crest-Derived Smooth Muscle Cells

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available There is growing recognition of cerebrovascular contributions to neurodegenerative diseases. In the walls of cerebral arteries, amyloid-beta (Aβ accumulation is evident in a majority of aged people and patients with cerebral amyloid angiopathy. Here, we leverage human pluripotent stem cells to generate vascular smooth muscle cells (SMCs from neural crest progenitors, recapitulating brain-vasculature-specific attributes of Aβ metabolism. We confirm that the lipoprotein receptor, LRP1, functions in our neural-crest-derived SMCs to mediate Aβ uptake and intracellular lysosomal degradation. Hypoxia significantly compromises the contribution of SMCs to Aβ clearance by suppressing LRP1 expression. This enabled us to develop an assay of Aβ uptake by using the neural crest-derived SMCs with hypoxia as a stress paradigm. We then tested several vascular protective compounds in a high-throughput format, demonstrating the value of stem-cell-based phenotypic screening for novel therapeutics and drug repurposing, aimed at alleviating amyloid burden.

    We report three patients with a cerebrovascular accident studied serially by MRI, including diffusion-weighted imaging (DWI). In case 1, DWI 1 day after the onset of left frontoparietal cortical infarcts showed no abnormal signal in the left corticospinal tract. DWI 12 days after onset showed high signal in the corticospinal tract, interpreted as early wallerian degeneration. This had disappeared by 22 days after onset. In case 2, DWI obtained 7 days after the onset of a right internal capsule lacunar infarct showed high signal from the right corticospinal tract in the brainstem, which was less marked 15 days after onset. In case 3, MRI on postnatal day 7 showed a cerebral haemorrhage in the right corona radiata and high signal from the right corticospinal tract on DWI. The latter disappeared by day 23. DWI shows early wallerian degeneration; transient signal abnormalities within 2 weeks of stroke should not be mistaken for new ischaemic lesions. (orig.)

    Panoramic radiography is a basic diagnostic tool in the dental field where calcifications are seen occasionally in the lateral parts of the x-ray. The differential diagnosis are carotid artery atheromas, calcified submandibular lymphnodes and sialoliths of the submandibular gland. 4007 panoramic radiographs (100%) from patients >40 years were scanned retrospectively. Special emphasis was given to the carotid artery territory (CAT). 225 soft tissue calcifications were found (5.6%). 144 patients had calcifications in the CAT (3.6%), 73 showed calcified submandibular lymphnodes (1.8%), and 8 (0.2%) sialoliths. The female to male ratio was 54.7%:45.3%. Pneumatic diseases were beside hypertension and smoking a risk factor for CAT calcification. Carotid artery atheromas are the main risk for cerebrovascular insults. Dentists can help to detect patients at risk for stroke. Their patients can be referred for further diagnostics (ultrasound).

    2002-01-01

    Using dipyridamole stress test to evaluate cerebral blood flow reserve in cerebrovascular disease (CVD). Dipyridamole stress tests were performed first, the baseline SPECT images were obtained under similar conditions 2-5 days later. By visual and semiquantitative analysis, the responses of cerebral blood flow to dipyridamole were divided into the following four patterns: A: The dipyridamole SPECT showed an expanded area of hypoperfusion, Asymmetry Index(AI) and Uptake Rate(UR) were all decreased; B: Rest images was normal but new hypoperfused areas appeared on stress test with decreased Al and UR; C: Hypoperfused areas were decreased in size or disappeared after stress test with increased Al and UR; D: No changes showed in cerebral perfusion imaging patterns, and in Al and UR between stress and rest studies. Dipyridarnole brain perfusion imaging may be helpful to the diagnosis of CVD, to the decision the therapeutic plan, and to predicting the therapeutic effect.

    The motivation of this work is the detection of cerebrovascular accidents by microwave tomographic imaging. This requires the solution of an inverse problem relying on a minimization algorithm (for example, gradient-based), where successive iterations consist in repeated solutions of a direct problem. The reconstruction algorithm is extremely computationally intensive and makes use of efficient parallel algorithms and high-performance computing. The feasibility of this type of imaging is conditioned on one hand by an accurate reconstruction of the material properties of the propagation medium and on the other hand by a considerable reduction in simulation time. Fulfilling these two requirements will enable a very rapid and accurate diagnosis. From the mathematical and numerical point of view, this means solving Maxwell's equations in time-harmonic regime by appropriate domain decomposition methods, which are naturally adapted to parallel architectures.

    Neuroimaging of cerebrovascular status and hemodynamics has vastly improved our understanding of stroke mechanisms and provided information for therapeutic decision-making. CT techniques are the most commonly used techniques due to wide availability, rapid acquisition and acceptable tolerance. Numerous multimodal CT techniques have been developed in the last few years. We summarize and explain the various multimodal CT acquisition techniques within three categories based on the scanning mode, namely static mode (single-phase CTA), multiple static mode (multi-phase CTA) and continuous mode (CT perfusion and dynamic CTA). Post-processing methods based on different acquisition modes are also introduced in an easy manner by focusing on the information extracted and products generated. We also describe the applications for these techniques along with their advantages and disadvantages. PMID:26967556

  1. Normal and abnormal patterns of cerebrovascular reserve tested by 133 Xe inhalation

    International Nuclear Information System (INIS)

    Cerebrovascular functional reserve was tested by noninvasive measurement of regional cerebral blood flow (nrCBF) at rest in quiet darkness and when repeated during standard multiple psychophysiologic activation. The test was applied to normal volunteers and patients with different neurologic disorders. The test included counting, conversation, music, and observing movements, while rCBF was measured over both cerebral hemispheres, brain stem, and cerebellum. In normal persons at rest, mean gray matter flow (Fg) values were the same for each hemisphere. Highest Fg values were observed in brain stem and both frontal regions. During activation in normal persons, there was a significant increase in Fg values over both hemispheres and in brain stem. During activation, three types of abnormal rCBF responses were seen: Demented patients showed no change, patients with vascular occlusion showed little or no increase over the ischemic hemisphere, and some patients with epilepsy showed excessive increases

Ocorreu, assim, um processo de mobilidade tanto ascendente quanto descendente, pois os que tinham origem nos "de cima" se proletarizaram enquanto os de origem popular ascenderam a uma profissão da classe média. A nova categoria, formada por essas duas frações, foi submetida a condições de vida e de trabalho determinadas pelo arrocho salarial. Analisamos este fenômeno tomando por base a Confederação dos Professores Primários do Brasil, que, por força das reformas educacionais da ditadura, cresceu numericamente e se transformou na Confederação dos Professores do Brasil.

It shows that teachers did not originate exclusively from the urban middle classes and fractions of the economical elite, but also from popular classes. An ascendant and descendant social mobilization process thus took place: those who originated from "upper" classes became proletarianized, while those from popular origin rose to a middle class profession. This new category, made up by these two sections, was submitted to standards of life and work determined by salary tightening. The analysis of this phenomenon is here carried out taking as a starting point the Confederation of Brazilian Primary Teachers, which, due to the dictatorship's educational reforms, grew numerically and transformed itself into the Confederation of Brazilian Teachers.

  7. Advantages and disadvantages of assist-systems in direct surgery for cerebrovascular diseases

    International Nuclear Information System (INIS)

    We evaluated the effectiveness of assist-systems such as endoscopy, navigation, and motor evoked potential (MEP) monitoring in terms of improving the safety and accuracy of surgery for cerebrovascular diseases. Since January 2000, the following devices have been used at our institution to assist in surgical procedures: an endoscope (diameter, 2.7 or 4.0 mm; tip angle, 30deg or 70deg) in 69 surgical procedures to treat cerebral aneurysms, a navigation system (Stealth Station) in 22 operations for cerebral aneurysms and arteriovenous or cavernous malformations, and MEP monitoring (bipolar or monopolar electrical stimulation of the motor cortex and EMG recording of the face, trunk and upper extremity contralateral to the stimulated side) in 11 operations for cerebral aneurysms or arteriovenous malformations. Endoscopy allowed visualization of the anatomical relationship between the aneurysm neck and the parent or perforated artery before clipping, and the location of the clip tip, occlusion of the perforated artery, or stenosis of the parent artery could be evaluated after clipping. Postoperative MR and/or CT images revealed an asymptomatic infarction of perforated artery in 4 patients. Navigation allowed prediction of the sites of aneurysms, cavernous malformations, or of the feeding arteries of arteriovenous malformations. This resulted in accurate approaches to these structures, although a brain shift in some patients was recognized by ultrasound imaging linked to the navigation system. Although MEP monitoring should have predicted postoperative motor function, MEP findings after clipping the neck of aneurysms or obliterating the arteriovenous malformation of a feeding artery were normal in all of the analyzed patients. Postoperative convulsive seizures developed in patients as a result of 20 mA of bipolar electrical stimulation. Endoscopy, navigation, and MEP monitoring are considered helpful for safe and accurate surgical treatment of cerebrovascular diseases

    Hypoxia-inducible factor I, a nuclear transcription factor, is induced by hypoxia. Hypoxia-inducible factor I, a heterodimeric DNA-binding protein, is composed of hypoxia-inducible factor 1α and hypoxia-inducible factor 1 β subunits, which are family members of the basic helix-loop-helix-PER, ARNT, SIM (PAS) protein. O2 concentration regulates hypoxia-inducible factor 1 activity via this subunit. Hypoxia-inducible factor 1α plays a major role in response to hypoxia and transcriptional activation, as well as in the target gene specificity of the DNA enhancer. Hypoxia-inducible factor 1β cannot be induced by hypoxia. This effect may be due to hypoxia-inducible factor 1 stability and activated conformation due to dimerization. Previous studies have shown that hypoxia-inducible factor 1 mRNA expression increases in the penumbra following ischemia/hypoxia. Hypoxia-inducible factor 1 plays an important role in brain tissue injury alter ischemia by affecting a series of target genes, elevating tolerance to hypoxia, and ensuring survival of neural cells. This article summarizes the structure, function, expression, regulatory mechanisms, biological effects, and significance of hypoxia-inducible factor 1 in patients with ischemic cerebrovascular disease. As a transcriptional activator, hypoxia- inducible factor 1 plays a key role in hypoxic responses by stabilizing the internal environment. It also has been shown to regulate the expression of several genes. The regulatory effects of hypoxia-inducible factor 1 in patients with ischemic cerebrovascular disease have been described. The present review re-examined the concept of brain protection at the level of gene regulation.

    Crossed cerebellar atrophy (CCA) was investigated by X-ray CT to establish the incidence, mechanism, and the relation to cerebral lesions in 130 cases of unilateral supratentorial cerebrovascular diseases. The cases consisted of 83 males and 47 females with cerebral infarction (65) and cerebral hemorrhage (65). The patients' average age was 57.6 years. Crossed cerebellar atrophy was demonstrated in 8 cases (6.2%), 6 of whom had massive cerebral infarction in the middle cerebral artery area (9.2%). The six cases of CCA caused by cerebral infarction had lesions in the frontal and temporal lobes. Two had a cerebral hemorrhage in the putamen and in the thalamus, respectively, accounting for 3.1% of the cases of cerebral hemorrhage. One case had putaminal hemorrhage, and another had thalamic hemorrhage. Cerebrovascular stroke had occured in these patients with CCA more than 2 months previously. In 5 of the 8 cases of CCA, atrophy was present in the basis pedunculi and the basis pontis on the side of the cerebral lesion. However, neither dilation nor deformity of the fourth ventricle was present in any of the patients, suggesting that none of the CCA patients had atrophy of the dentate nucleus. The CCA patients had massive cerebral lesion in the frontal and temporal lobes or atrophy of the basis pedunculi and basis pontis, suggesting the presence of the transsynaptic degeneration of the cortico-ponto-cerebellar pathway. In the case of the thalamic hemorrhage, who had not hemorrhagic lesion in the frontal and temporal lobes, atrophy of the basis peduncli and basis pontis was not observed. Though dilation or deformity of the fourth ventricle is not observed in this case, presence of the degeneration of the dentate-rubro-thalamic pathway cannot be denied. CCA seems to be caused by both the transsynaptic degeneration of the cortico-ponto-cerebellar pathway and the dentate-rubro-thalamic pathway.

  10. Dynamic cerebral autoregulation and cerebrovascular reactivity: a comparative study in lacunar infarct patients

    International Nuclear Information System (INIS)

    The major purpose of this study was to simultaneously evaluate dCA before and shortly after cerebral vasodilatation evoked by infusion of acetazolamide (ACZ). It was questioned if and to what degree dCA was changed after ACZ infusion. Using 15 mg kg−1 ACZ infusion cerebrovascular reactivity (CVR) was assessed in 29 first ever lacunar stroke patients (19 M/10 F). During the CVR-test, the electrocardiogram, non-invasive finger arterial blood pressure (ABP) and middle cerebral artery blood flow velocity (CBFV) were recorded. DCA based on spontaneous blood pressure variations was evaluated in 24 subjects by linear transfer function analysis. Squared coherence, gain and phase angle in the frequency range of autoregulation (0.04–0.16 Hz) were compared before and after ACZ infusion. After ACZ infusion, median phase angle decreased significantly (p < 0.005 Wilcoxon) to 0.77 rad compared to a pre-test baseline value of 1.05 rad, indicating less efficient dCA due to ACZ. However, post-test phase values are still mostly within the normal range. Poor and statistically non-significant correlations were found between CVR and absolute dCA phase angle. It can be concluded that CVR testing with body weight adjusted infusion of ACZ lowers dCA performance but by no means exhausts dCA, suggesting that in this way maximal CVR is not determined. Characterizing dCA based on transfer function analysis of ABP to CBFV needs no provocation and adverse patient effects are minimal. The poor correlation between CVR and dCA phase angle supports an interpretation that CVR and dCA study different mechanisms of cerebrovascular control

    Full Text Available Coronary artery disease (CAD poses a risk to the cerebrovascular function of older adults and has been linked to impaired cognitive abilities. Using magnetic resonance perfusion imaging, we investigated changes in resting cerebral blood flow (CBF and cerebrovascular reactivity (CVR to hypercapnia in 34 coronary artery disease (CAD patients and 21 age-matched controls. Gray matter volume images were acquired and used as a confounding variable to separate changes in structure from function. Compared to healthy controls, CAD patients demonstrated reduced CBF in the superior frontal, anterior cingulate, insular, pre- and post-central gyri, middle temporal and superior temporal regions. Subsequent analysis of these regions demonstrated decreased CVR in the anterior cingulate, insula, postcentral and superior frontal regions. Except in the superior frontal and precentral regions, regional reductions in CBF and CVR were identified in brain areas where no detectable reductions in gray matter volume were observed, demonstrating that these vascular changes were independent of brain atrophy. Because aerobic fitness training can improve brain function, potential changes in regional CBF were investigated in the CAD patients after completion of a 6-month exercise-based cardiac rehabilitation program. Increased CBF was observed in the bilateral anterior cingulate, as well as recovery of CBF in the dorsal aspect of the right anterior cingulate, where the magnitude of increased CBF was roughly equal to the reduction in CBF at baseline compared to controls. These exercise-related improvements in CBF in the anterior cingulate is intriguing given the role of this area in cognitive processing and regulation of cardiovascular autonomic control.

    Coronary artery disease (CAD) poses a risk to the cerebrovascular function of older adults and has been linked to impaired cognitive abilities. Using magnetic resonance perfusion imaging, we investigated changes in resting cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) to hypercapnia in 34 CAD patients and 21 age-matched controls. Gray matter volume (GMV) images were acquired and used as a confounding variable to separate changes in structure from function. Compared to healthy controls, CAD patients demonstrated reduced CBF in the superior frontal, anterior cingulate (AC), insular, pre- and post-central gyri, middle temporal, and superior temporal regions. Subsequent analysis of these regions demonstrated decreased CVR in the AC, insula, post-central and superior frontal regions. Except in the superior frontal and precentral regions, regional reductions in CBF and CVR were identified in brain areas where no detectable reductions in GMV were observed, demonstrating that these vascular changes were independent of brain atrophy. Because aerobic fitness training can improve brain function, potential changes in regional CBF were investigated in the CAD patients after completion of a 6-months exercise-based cardiac rehabilitation program. Increased CBF was observed in the bilateral AC, as well as recovery of CBF in the dorsal aspect of the right AC, where the magnitude of increased CBF was roughly equal to the reduction in CBF at baseline compared to controls. These exercise-related improvements in CBF in the AC is intriguing given the role of this area in cognitive processing and regulation of cardiovascular autonomic control. PMID:26779011

    Full Text Available Background: There are a growing number of studies suggesting that depression may increase the risk of stroke. Impaired autoregulation of vascular tone may contribute to a higher risk of developing cerebrovascular diseases. Cerebrovascular reactivity (CVR reflects the compensatory dilatory capacity of cerebral arterioles to a dilatory stimulus and is an important mechanism that ensures constant cerebral blood flow. There is a hypothesis that CVR is reduced in major depression, which would explain the association between depression and stroke. Objectives: The aim of this study was to investigate the effect of depression on CVR in cerebral vessels by comparing CVR during the depression phase with that during remission. Material and Methods: Using the apnea test, we assessed CVR in 16 patients with unipolar depression during disease and after remission of disease by calculating the increase in cerebral blood flow velocity after breath-holding (the apnea test. Blood flow velocities were measured by transcranial Doppler ultrasound (TCD. Results: CVR was significantly reduced in the depression phase in comparison to that in the remission phase. However, this change was not seen in all the patients. Conclusion: CVR was reduced in most of the depressed patients. The decreased CVR, as indicated by the changes in peak systolic velocity (PSV and mean flow velocity (MFV of the middle cerebral artery, in depressed patients was more marked on the right side, which could point to a vascular basis for some kinds of depression. We recommend that other studies, with larger samples, be done; future studies should assess whether the changes in the CVR varies with the severity and type of depression.

    OBJECT Surgery requires careful coordination of multiple team members, each playing a vital role in mitigating errors. Previous studies have focused on eliciting errors from only the attending surgeon, likely missing events observed by other team members. METHODS Surveys were administered to the attending surgeon, resident surgeon, anesthesiologist, and nursing staff immediately following each of 31 cerebrovascular surgeries; participants were instructed to record any deviation from optimal course (DOC). DOCs were categorized and sorted by reporter and perioperative timing, then correlated with delays and outcome measures. RESULTS Errors were recorded in 93.5% of the 31 cases surveyed. The number of errors recorded per case ranged from 0 to 8, with an average of 3.1 ± 2.1 errors (± SD). Overall, technical errors were most common (24.5%), followed by communication (22.4%), management/judgment (16.0%), and equipment (11.7%). The resident surgeon reported the most errors (52.1%), followed by the circulating nurse (31.9%), the attending surgeon (26.6%), and the anesthesiologist (14.9%). The attending and resident surgeons were most likely to report technical errors (52% and 30.6%, respectively), while anesthesiologists and circulating nurses mostly reported anesthesia errors (36%) and communication errors (50%), respectively. The overlap in reported errors was 20.3%. If this study had used only the surveys completed by the attending surgeon, as in prior studies, 72% of equipment errors, 90% of anesthesia and communication errors, and 100% of nursing errors would have been missed. In addition, it would have been concluded that errors occurred in only 45.2% of cases (rather than 93.5%) and that errors resulting in a delay occurred in 3.2% of cases instead of the 74.2% calculated using data from 4 team members. Compiled results from all team members yielded significant correlations between technical DOCs and prolonged hospital stays and reported and actual delays (p = 0

Se valoran las prácticas de gobierno que relacionaron, por una parte, a los vecinos, sujetos a la jurisdicción de los alcaldes y el corregidor, y, por otra, a los soldados, beneficiados por el fuero militar. Muchas de las discordias estuvieron causadas por las competencias de jurisdicción entre los distintos poderes, por el aumento de atribuciones de los militares en los contextos bélicos, por el control ejercido por los militares en las milicias concejiles y por la participación de los soldados en las instituciones de gobierno de la ciudad. Este estudio nos permite comprender el proceso de definición de una identidad particular en las ciudades fronterizas, sustentada en la exclusión de la comunidad de todo elemento que intentara segregarse del marco de acción de las autoridades urbanas y de la jurisdicción ordinaria.From different viewpoints, this article analyzes urban frontier coastal spaces in early modern Castile (16th and 17th centuries.

    Full Text Available Las compañías militares privadas (CMPs han generado muchas inquietudes en el público debido a su notoria participación en los conflictos de Afganistán e Irak. La amplia cobertura de sus actividades en los medios de comunicación ha contribuido a presentarlos como un nuevo fenómeno. Sin embargo, su surgimiento y proliferación se dan durante décadas de un proceso de transformación del estado y penetración gradual de su monopolio sobre el uso legítimo de la fuerza. Este artículo discute que la Nueva Gerencia Pública ha enlazado dinámicas históricas importantes de una manera que ayuda a explicar la continua legitimación y expansión del mercado de los servicios militares privados en el nuevo milenio. Se espera que el enfoque técnico del artículo contribuya a la apertura de un debate constructivo, ya que las tendencias actuales apuntan a la expansión de las actividades de las compañías militares privadas en el mercado hispano parlante. The involvement of Private Military Companies (PMCs in the conflicts in Afghanistan and Iraq has engendered many concerns in the public. Although the wide coverage of their activities by the news media has contributed to present PMCs anew, their proliferation builds on decades of state transformation and the gradual penetration of the state monopoly of violence by private actors. This article argues that New Public Management has enmeshed historical dynamics in a way that helps explaining the apparently novel nature of the phenomenon and the broader consolidation of the market for private military services in the twenty-first century. It is hoped that the technical nature of the argument will contribute to open up a constructive debate at a time when unfolding trends suggest an expansion of the activities of PMCs in Latin America and beyond.

    In this paper, we consider two hospitals with different perceived quality of care competing to capture a fraction of the total market demand. Patients select the hospital that provides the highest utility, which is a function of price and the patient's perceived quality of life during their life expectancy. We consider a market with a single class of patients and show that depending on the market demand and perceived quality of care of the hospitals, patients may enjoy a positive utility. Moreover, hospitals share the market demand based on their perceived quality of care and capacity. We also show that in a monopoly market (a market with a single hospital) the optimal demand captured by the hospital is independent of the perceived quality of care. We investigate the effects of different parameters including the market demand, hospitals' capacities, and perceived quality of care on the fraction of the demand that each hospital captures using some numerical examples.

    Objective To investigate the predictive value of serum hypersensitivity C-reactive protein in diabetes pa-tients with cerebrovascular accident. Methods 66 cases of type 2 diabetes combined with cerebrovascular accident from Mau 2012 to May 2013 in the Southern District of the Second People's Hospital of Yibin City were selected as cere-brovascular accident group, 66 cases of type 2 diabetes without cerebrovascular accident in the same term were chosen as simple diabetes group, 66 cases of healthy people were selected as control group. Fasting blood-glucose (FRG), oral glucose tolerance test (OGTT), hs-CRP level among the three groups were detected and compared. Results①The value of FPG, 2 h PG in cerebrovascular accident group [(8.53±2.03), (13.89±2.27) mmol/L] and simple diabetes group [(8.62±1.35), (14.19±1.86) mmol/L] were all higher than those in control group [(4.01±1.10), (6.17±1.71) mmol/L], the differences were statistically significant (P0.05).② The differences of hs-CRP level and abnormal proportion among the three groups were statistically significant (F= 3.973, χ2 = 4.730, P0.05)。②三组间hs-CRP水平及异常比例比较,差异均有统计学意义(F=3.973,χ2=4.730,P<0.05);其中脑血管意外组hs-CRP水平[(12.58±3.53)μg/mL]高于单纯糖尿病组[(4.87±1.94)mg/L]及对照组[(2.03±0.71)mg/L],差异有统计学意义(P<0.05);单纯糖尿病组hs-CRP水平高于对照组,差异有统计学意义(P<0.05)。结论 hs-CRP对糖尿病合并脑血管意外具有明显的预测价值,可作为脑血管事件的预测因子。
