Vena AB, Cabré X, Piñol R, Molina J, Purroy F. Assessment of incidence and trends in cerebrovascular disease in the healthcare district of Lleida (Spain) in the period 2010-2014. Neurologia 2022; 37:631-638. [PMID: 31952889 DOI: 10.1016/j.nrl.2019.10.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Revised: 08/06/2019] [Accepted: 10/13/2019] [Indexed: 10/25/2022] Open
Abstract
OBJECTIVES This study aimed to determine the incidence and trends of cerebrovascular disease (CVD) in the healthcare district of Lleida. MATERIAL AND METHODS We performed a population-based prospective cohort study including the entire population of the healthcare district of Lleida (440 000 people). Information was gathered from the minimum basic data set from the emergency department and hospital discharges for the period from January 2010 to December 2014. All types of stroke were included. We evaluated crude and age-standardised rates using the world population as a reference. Patients without neuroimaging confirmation of the diagnosis were excluded. RESULTS We identified 4397 patients: 1617 (36.8%) were aged 80 years or over; 3969 (90.3%) presented ischaemic stroke, and 1741 (39.6%) were women. The crude incidence rate ranged from 192 (95% confidence interval [CI], 179-205) to 211 (95% CI, 197-224) cases per 100 000 population, in 2012 and 2013, respectively. Age-standardised rates ranged from 93 (95% CI, 86-100) to 104 (95% CI, 96-111) cases per 100 000 population, in 2012 and 2013, respectively. For all years, incidence rates increased with age, and were significantly higher among men than among women. CONCLUSION The impact of CVD in Lleida is comparable to that observed in other European regions. However, population ageing induces a high crude incidence rate, which remained stable over the five-year study period.

Abstract
Vascular Dementia (VaD) is a neurocognitive disorder caused by reduced blood flow to the brain tissue, resulting in infarction, and is the second most common type of dementia. The complement and coagulation systems are evolutionary host defence mechanisms activated by acute tissue injury to induce inflammation, clot formation and lysis; recent studies have revealed that these systems are closely interlinked. Overactivation of these systems has been recognised to play a key role in the pathogenesis of neurological disorders such as Alzheimer's disease and multiple sclerosis, however their role in VaD has not yet been extensively reviewed. This review aims to bridge the gap in knowledge by collating current understanding of VaD to enable identification of complement and coagulation components involved in the pathogenesis of this disorder that may have their effects amplified or supressed by crosstalk. Exploration of these mechanisms may unveil novel therapeutic targets or biomarkers that would improve current treatment strategies for VaD.

Abstract
Supplemental Digital Content is available in the text. Background and Purpose: Stroke is reported as a consequence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in several reports. However, data are sparse regarding the details of these patients in a multinational and large scale. Methods: We conducted a multinational observational study on features of consecutive acute ischemic stroke, intracranial hemorrhage, and cerebral venous or sinus thrombosis among SARS-CoV-2–infected patients. We further investigated the risk of large vessel occlusion, stroke severity as measured by the National Institutes of Health Stroke Scale, and stroke subtype as measured by the TOAST (Trial of ORG 10172 in Acute Stroke Treatment) criteria among patients with acute ischemic stroke. In addition, we explored the neuroimaging findings, features of patients who were asymptomatic for SARS-CoV-2 infection at stroke onset, and the impact of geographic regions and countries’ health expenditure on outcomes. Results: Among the 136 tertiary centers of 32 countries who participated in this study, 71 centers from 17 countries had at least 1 eligible stroke patient. Of 432 patients included, 323 (74.8%) had acute ischemic stroke, 91 (21.1%) intracranial hemorrhage, and 18 (4.2%) cerebral venous or sinus thrombosis. A total of 183 (42.4%) patients were women, 104 (24.1%) patients were <55 years of age, and 105 (24.4%) patients had no identifiable vascular risk factors. Among acute ischemic stroke patients, 44.5% (126 of 283 patients) had large vessel occlusion; 10% had small artery occlusion according to the TOAST criteria. We observed a lower median National Institutes of Health Stroke Scale (8 [3–17] versus 11 [5–17]; P=0.02) and higher rate of mechanical thrombectomy (12.4% versus 2%; P<0.001) in countries with middle-to-high health expenditure when compared with countries with lower health expenditure. Among 380 patients who had known interval onset of the SARS-CoV-2 and stroke, 144 (37.8%) were asymptomatic at the time of admission for SARS-CoV-2 infection. Conclusions: We observed a considerably higher rate of large vessel occlusions, a much lower rate of small vessel occlusion and lacunar infarction, and a considerable number of young stroke when compared with the population studies before the pandemic. The rate of mechanical thrombectomy was significantly lower in countries with lower health expenditures.

Abstract
Objective: Irritability is a very common symptom after stroke and a source of a great deal of distress to patients and caretakers. We evaluated the psychometric properties of the Irritability Questionnaire (IQ) in a sample of patients with stroke.Methods: we recruited 94 participants (47 stroke patients and 47 healthy controls) that participated in a 6-month longitudinal observational study. The IQ includes three dimensions in the assessment: emotion, cognition, and behavior. IQ has two subscales: The Irritability Questionnaire (IRQ) and the Carer's Irritability Questionnaire (CIRQ). Internal consistency, convergent validity, and sensitivity to change were evaluated for both IRQ and CIRQ.Results: Cronbach's alpha for the IRQ was 0.91 (95% CI: 0.76 to 0.87), whereas for the CIRQ was 0.92 (95% CI: 0.89 to 0.94). Convergent validity was good for both subscales. IRQ did not show sensitivity to change at 6 months (p-value = 0.99), while CIRQ showed moderate changes (-0.29, p-value = 0.124).Conclusions: IQ presented good psychometric properties to assess irritability in stroke. The tool detected significant differences between groups (stroke and healthy controls) and can be considered a valid instrument for clinical and research purposes.

Abstract
With increased numbers of older people a higher burden of neurological disorders worldwide is predicted. Stroke and other cerebrovascular diseases do not necessarily present with different phenotypes in Africa but their incidence is rising in tandem with the demographic change in the population. Age remains the strongest irreversible risk factor for stroke and cognitive impairment. Modifiable factors relating to vascular disease risk, diet, lifestyle, physical activity and psychosocial status play a key role in shaping the current spate of stroke related diseases in Africa. Hypertension is the strongest modifiable risk factor for stroke but is also likely associated with co-inheritance of genetic traits among Africans. Somewhat different from high-income countries, strokes attributed to cerebral small vessel disease (SVD) are higher >30% among sub-Saharan Africans. Raised blood pressure may explain most of the incidence of SVD-related strokes but there are likely other contributing factors including dyslipidaemia and diabetes in some sectors of Africa. However, atherosclerotic and cardioembolic diseases combined also appear to be common subtypes as causes of strokes. Significant proportions of cerebrovascular diseases are ascribed to various forms of infectious disease including complications of human immunodeficiency virus. Cerebral SVD leads to several clinical manifestations including gait disturbance, autonomic dysfunction and depression. Pathological processes are characterized by arteriolosclerosis, lacunar infarcts, perivascular spaces, microinfarcts and diffuse white matter changes, which can now all be detected on neuroimaging. Except for isolated cases of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy or CADASIL, hereditary arteriopathies have so far not been reported in Africa. Prevalence estimates of vascular dementia (2-3%), delayed dementia after stroke (10-20%) and vascular cognitive impairment (30-40%) do not appear to be vastly different from those in other parts of the world. However, given the current demographic transition in both urban and rural settings these figures will likely rise. Wider application of neuroimaging modalities and implementation of stroke care in Africa will enable better estimates of SVD and other subtypes of stroke. Stroke survivors with SVD type pathology are likely to have low mortality and therefore portend increased incidence of dementia.

Abstract
It is unanimously accepted that stroke is a highly heterogeneous disorder. Different subtypes of ischemic stroke may have different risk factors, clinical features, and prognoses. The aim of this study was to evaluate the risk factors, clinical characteristics, and prognoses of different subtypes of ischemic stroke defined by the Trial of ORG10172 in Acute Stroke Treatment (TOAST) criteria. We prospectively analyzed the data from 530 consecutive patients who were admitted to our hospital with acute ischemic stroke within 7 days of stroke onset during the study period. Standardized data assessment was used and the cause of ischemic stroke was classified according to the TOAST criteria. Patients were followed up till 30 and 90 days after stroke onset. It was found that large-artery atherosclerosis was the most frequent etiology of stroke (37.4%), and showed the highest male preponderance, the highest prevalence of previous transient ischemic attack, and the longest hospital stay among all subtypes. Small artery disease (36.4%) was associated with higher body mass index, higher plasma triglycerides, and lower plasma high-density lipoprotein cholesterol than cardioembolism. Cardioembolism (7.7%), which was particularly common in the elderly (i.e., individuals aged 65 years and older), showed the highest female preponderance, the highest prevalence of atrial fibrillation, the earliest presentation to hospital after stroke onset, the most severe symptoms on admission, the maximum complications associated with an adverse outcome, and the highest rate of stroke recurrence and mortality. Our results suggest that ischemic stroke should be regarded as a highly heterogeneous disorder. Studies involving risk factors, clinical features, and prognoses of ischemic stroke should differentiate between etiologic stroke subtypes.

Abstract
Vascular dementia (VaD) is widely recognised as the second most common type of dementia. Consensus and accurate diagnosis of clinically suspected VaD relies on wide-ranging clinical, neuropsychological and neuroimaging measures in life but more importantly pathological confirmation. Factors defining subtypes of VaD include the nature and extent of vascular pathologies, degree of involvement of extra and intracranial vessels and the anatomical location of tissue changes as well as time after the initial vascular event. Atherosclerotic and cardioembolic diseases combined appear the most common subtypes of vascular brain injury. In recent years, cerebral small vessel disease (SVD) has gained prominence worldwide as an important substrate of cognitive impairment. SVD is characterised by arteriolosclerosis, lacunar infarcts and cortical and subcortical microinfarcts and diffuse white matter changes, which involve myelin loss and axonal abnormalities. Global brain atrophy and focal degeneration of the cerebrum including medial temporal lobe atrophy are also features of VaD similar to Alzheimer's disease. Hereditary arteriopathies have provided insights into the mechanisms of dementia particularly how arteriolosclerosis, a major contributor of SVD promotes cognitive impairment. Recently developed and validated neuropathology guidelines indicated that the best predictors of vascular cognitive impairment were small or lacunar infarcts, microinfarcts, perivascular space dilation, myelin loss, arteriolosclerosis and leptomeningeal cerebral amyloid angiopathy. While these substrates do not suggest high specificity, VaD is likely defined by key neuronal and dendro-synaptic changes resulting in executive dysfunction and related cognitive deficits. Greater understanding of the molecular pathology is needed to clearly define microvascular disease and vascular substrates of dementia. This article is part of the Special Issue entitled 'Cerebral Ischemia'.

Abstract
BACKGROUND The study of sex differences on stroke incidence, prevalence and mortality is an emerging field of stroke epidemiology and care. AIMS This study sought to determine the information available on stroke epidemiology in women worldwide and possible sex differences in stroke epidemiology, and, if so, describe the nature of these differences and whether they are consistent across countries/groups of countries. SUMMARY We searched the available literature in English published between 1 January 2008 and 5 May 2015. Out of 17.789 papers only 56 peer-reviewed papers (29 community-based studies, 17 retrospective studies, 6 reviews, and 4 cross-sectional studies) have been included in the study. This review adopted the epidemiologic transition theory, which classifies countries into four stages according to their levels of industrialization and economy. For the first and second stages, reliable registries and health certification are lacking, and therefore our sought after data were very limited.In the third stage, specifically for Eastern Europe (post-socialist countries), the burden from stroke in women was on the rise, while in the fourth stage, despite an aging population, decreases in stroke incidence, prevalence and mortality have been observed, even in subjects older than 80 years for both sexes. However, regarding studies of US populations, these trends for women were less pronounced for African Americans, and Hispanics as well as Indians. This suggests a "gender-gap" regarding access to treatment and care.In conclusion, identifying the presence of differing global burden between the sexes will allow us to better understand how to prevent, treat, and manage both men and women.

Abstract
The burden of stroke is increasing due to aging population and unhealthy lifestyle habits. The considerable rise in atrial fibrillation (AF) is due to greater diffusion of risk factors and screening programs. The link between AF and ischemic stroke is strong. The subtype most commonly associated with AF is cardioembolic stroke, which is particularly severe and shows the highest rates of mortality and permanent disability. A trend toward a higher prevalence of cardioembolic stroke in high-income countries is probably due to the greater diffusion of AF and the control of atherosclerotic of risk factors.

Abstract
INTRODUCTION Almost one-third of ischemic strokes has an unknown etiology and are classified as cryptogenic stroke. Paradoxical embolism because of a patent foramen ovale (PFO) is detected in 40%-50% of these patients. Recently, PFO has been reported as a risk factor for patients of all age groups. METHODS In this study, 1080 ischemic stroke patients admitted to our clinic (2011-2013) were retrospectively evaluated. Age, sex, risk factors, complete blood count, vasculitis, biochemical and hypercoagulability tests, magnetic resonance imaging, magnetic resonance angiography, transthoracic echocardiography, transeosophageal echocardiography (TEE) findings, and therapeutic approaches were evaluated. RESULTS The age range of the participants (seven male and four female patients) was 20-60 years (mean=43.09±11.13 years). Hemiparesis (n=10), diplopia (n=2), hemianopsia (n=2), and dysarthria (n=2) were the main findings of the neurological examinations. Patient medical history revealed hypertension (n=3), asthma (n=1), deep venous thrombosis (n=1), and smoking (n=4). Diffusion-weighted imaging showed middle cerebral artery (n=8) and posterior cerebral artery (n=3) infarctions. In one case, symptomatic severe carotid stenosis was detected. In eight cases, TEE showed PFO without any other abnormalities, but PFO was associated with atrial septal aneurysm in two cases, and in one case it was associated with ventricular hypokinesia and pulmonary arterial hypertension. Antiplatelet therapy was applied to nine patients and percutaneous PFO closure operation to two patients. In a 2-year follow-up, no recurrent ischemic stroke was recorded. CONCLUSION PFO, especially in terms of the etiology of cryptogenic stroke in young patients, should not be underestimated. We want to emphasize the importance of TEE in identifying potential cardioembolic sources not only in young but also in all ischemic stroke patients with unknown etiology; we also discuss the controversial management options of PFO.

Abstract
BACKGROUND AND OBJECTIVE The aim of the present study was to determine the national burden of cerebrovascular diseases in the adult population of Spain. PATIENTS AND METHODS Cross-sectional, descriptive population-based study. We calculated the disability-adjusted life years (DALY) metric using country-specific data from national statistics and epidemiological studies to obtain representative outcomes for the Spanish population. DALYs were divided into years of life lost due to premature mortality (YLLs) and years of life lived with disability (YLDs). DALYs were estimated for the year 2008 by applying demographic structure by sex and age-groups, cause-specific mortality, morbidity data and new disability weights proposed in the recent Global Burden of Disease study. In the base case, neither YLLs nor YLDs were discounted or age-weighted. Uncertainty around DALYs was tested using sensitivity analyses. RESULTS In Spain, cerebrovascular diseases generated 418,052 DALYs, comprising 337,000 (80.6%) YLLs and 81,052 (19.4%) YLDs. This accounts for 1,113 DALYs per 100,000 population (men: 1,197 and women: 1,033) and 3,912 per 100,000 in those over the age of 65 years (men: 4,427 and women: 2,033). Depending on the standard life table and choice of social values used for calculation, total DALYs varied by 15.3% and 59.9% below the main estimate. CONCLUSIONS Estimates provided here represent a comprehensive analysis of the burden of cerebrovascular diseases at a national level. Prevention and control programmes aimed at reducing the disease burden merit further priority in Spain.

Abstract
BACKGROUND Although stroke is the second leading cause of death worldwide, no comprehensive and comparable assessment of incidence, prevalence, mortality, disability, and epidemiological trends has been estimated for most regions. We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010) to estimate the global and regional burden of stroke during 1990-2010. METHODS We searched Medline, Embase, LILACS, Scopus, PubMed, Science Direct, Global Health Database, the WHO library, and WHO regional databases from 1990 to 2012 to identify relevant studies published between 1990 and 2010.We applied the GBD 2010 analytical technique (DisMod-MR), based on disease-specific, pre-specified associations between incidence, prevalence, and mortality, to calculate regional and country-specific estimates of stroke incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) lost by age group (<75 years, ≥ 75 years, and in total)and country income level (high-income, and low-income and middle-income) for 1990, 2005, and 2010. FINDINGS We included 119 studies (58 from high-income countries and 61 from low-income and middle-income countries). From 1990 to 2010, the age-standardised incidence of stroke significantly decreased by 12% (95% CI 6-17)in high-income countries, and increased by 12% (-3 to 22) in low-income and middle-income countries, albeit nonsignificantly. Mortality rates decreased significantly in both high income (37%, 31-41) and low-income and middle income countries (20%, 15-30). In 2010, the absolute numbers of people with fi rst stroke (16・9 million), stroke survivors (33 million), stroke-related deaths (5・9 million), and DALYs lost (102 million) were high and had significantly increased since 1990 (68%, 84%, 26%, and 12% increase, respectively), with most of the burden (68・6% incident strokes, 52・2% prevalent strokes, 70・9% stroke deaths, and 77・7% DALYs lost) in low-income and middle-income countries. In 2010, 5・2 million (31%) strokes were in children (aged <20 years old) and young and middle-aged adults(20-64 years), to which children and young and middle-aged adults from low-income and middle-income countries contributed almost 74 000 (89%) and 4・0 million (78%), respectively, of the burden. Additionally, we noted significant geographical differences of between three and ten times in stroke burden between GBD regions and countries. More than 62% of new strokes, 69・8% of prevalent strokes, 45・5% of deaths from stroke, and 71・7% of DALYs lost because of stroke were in people younger than 75 years. INTERPRETATION Although age-standardised rates of stroke mortality have decreased worldwide in the past two decades,the absolute number of people who have a stroke every year, stroke survivors, related deaths, and the overall global burden of stroke (DALYs lost) are great and increasing. Further study is needed to improve understanding of stroke determinants and burden worldwide, and to establish causes of disparities and changes in trends in stroke burden between countries of different income levels.

Abstract
Approximately one in four ischemic strokes is of cardioembolic origin. Non-valvular atrial fibrillation accounts for 50% of these cases, followed by myocardial infarction, intraventricular thrombus, valvular heart disease and a miscellany of causes. The incidence of embolic heart disease in the population could be about 30 cases per 100,000 inhabitants per year, and its prevalence between 5 and 10 cases per 1,000 persons aged 65 years or older. Hospital mortality is high, and 5-year survival is only one out of every five patients. The recurrence rate of this type of stroke is about 12% at 3 months, higher than that of non-cardioembolic stroke. The severity of cardioembolic strokes and the resulting disability are greater than with non-cardioembolic stroke. Age, a history of stroke or transient ischemic attack, hypertension, diabetes and heart failure play a role in stroke with atrial fibrillation as additional risk factors for future embolisms. Stroke rates can reach over 20% per year and therefore the prevention and treatment of these events are of paramount importance.

Abstract
The association of cerebral white matter lesions (WMLs) with cognitive status is not well understood in middle-aged individuals. Our aim was to determine the specific contribution of periventricular hyperintensities (PVHs) and deep white matter hyperintensities (DWMHs) to cognitive function in a community sample of asymptomatic participants aged 50 to 65 years. One hundred stroke- and dementia-free adults completed a comprehensive neuropsychological battery and brain MRI protocol. Participants were classified according to PVH and DWMH scores (Fazekas scale). We dichotomized our sample into low grade WMLs (participants without or with mild lesions) and high grade WMLs (participants with moderate or severe lesions). Analyses were performed separately in PVH and DWMH groups. High grade DWMHs were associated with significantly lower scores in executive functioning (-0.45 standard deviations [SD]), attention (-0.42 SD), verbal fluency (-0.68 SD), visual memory (-0.52 SD), visuospatial skills (-0.79 SD), and psychomotor speed (-0.46 SD). Further analyses revealed that high grade DWMHs were also associated with a three- to fourfold increased risk of impaired scores (i.e.,<1.5 SD) in executive functioning, verbal fluency, visuospatial skills, and psychomotor speed. Our findings suggest that only DWMHs, not PVHs, are related to diminished cognitive function in middle-aged individuals. (JINS, 2012, 18, 1-12).

Abstract
Stroke is the most debilitating cardiovascular event. It has a variety of causes that may be present simultaneously. In young or otherwise healthy people, the search for a patent foramen ovale (PFO) has become standard. In stroke of the elderly, atherosclerosis and atrial fibrillation are in the foreground but the PFO should not be ignored. The risk of a PFO-related stroke over time is controversial and so is its prevention by device closure. The association of proximal aortic plaques in arteries subtending the brain and stroke is considered strong, ignoring that it is as putative as that of the PFO. Statins can prevent progression of such plaques. Antiplatelet agents in asymptomatic and surgical endarterectomy in symptomatic patients or highly ulcerated lesions are the treatment of choice. Stenting with protection devices was shown competitive in selected patients.

Abstract
The TOAST classification divides patients with ischemic stroke into five subgroups according to the presumed etiological mechanism. The aims of the present study were to evaluate the distribution of the different etiological stroke subtypes in a hospital-based sample of stroke patients, and to investigate the association between important risk factors and stroke subtypes. A total of 210 patients with a first-ever ischemic stroke admitted to the stroke unit of Asker and Bærum Hospital in Norway between February 2007 and July 2008 were enrolled in the study. Information on vascular risk factors was collected at admittance, examination of neurological deficits was carried out during their stay, and classification was made according to the TOAST criteria. According to the TOAST classification, 24 (11.4%) of the patients suffered from large vessel disease, 66 (31.4%) from cardioembolic disease, 66 (31.4%) from small vessel disease and 54 (25.7%) from a stroke of undetermined etiology. The presence of hyperlipidemia and atrial fibrillation varied significantly between the different subtypes. In multivariate analyses, hyperlipidemia [odds ratio (OR) 2.46, 95% confidence interval (CI) 1.32-4.60] and current smoking (OR 2.06, 95% CI 1.04-4.08) were the only variables that were related to small vessel disease. Small vessel disease was observed more frequently and large vessel disease less frequently than previously reported. Small vessel disease was significantly associated with hyperlipidemia and current smoking. Our study supports the view that the etiology of lacunar strokes is multifactorial.

Abstract
INTRODUCTION AND OBJECTIVES Knowledge about the incidence of cardiovascular disease in Spain is limited, particularly about emergent conditions such as peripheral arterial disease and heart failure. The objective of this study was to determine the incidence of these conditions in a primary care setting. METHODS A prospective population-based cohort study was carried out in two health centers in Barcelona, Spain. It included 931 randomly selected individuals, aged 35 to 84 years, without cardiovascular disease who were followed for 10 years. We assessed the incidence of ischemic heart disease (i.e. myocardial infarction and angina), cerebrovascular disease (i.e. stroke and transient ischemic attack), peripheral arterial disease of the lower extremities, and heart failure. RESULTS The most frequently occurring condition was ischemic heart disease (cumulative incidence, 6.1%), followed by cerebrovascular disease (4.3%), heart failure (3.0%), and peripheral arterial disease (1.9%). These conditions were more frequent in patients aged >65 years (cumulative incidence, 9.6%, 8.9%, 4.6% and 3.1%, respectively). The most frequent comorbid conditions were ischemic heart disease and cerebrovascular disease. The incidence of acute myocardial infarction was greater in men (P< .001), but there was no significant difference for other conditions. The adjusted incidence (European population) per 100,000 inhabitants per year in men and women, respectively, was: 605 and 115 for acute myocardial infarction; 238 and 220 for angina; 300 and 327 for stroke; 125 and 115 for transient ischemic attack; 136 and 178 for peripheral arterial disease; and 219 and 267 for heart failure. CONCLUSIONS The incidence of cardiovascular disease was lower than in other developed countries. Disease occurred more frequently in patients aged >65 years. Ischemic heart disease remained the most common, with heart failure being a notable emergent condition.

Abstract
PURPOSE To evaluate the validity of recorded diagnoses of ischemic cerebrovascular events requiring hospitalization within The Health Improvement Network (THIN) UK primary care database. METHODS We identified 15 397 individuals aged 40-84 years with a first recorded ischemic event in 2000-2004. Of these, 4239 had a code suggestive of a hospitalization within 2 weeks of the event. A three-step strategy was used to validate the records of these patients: manual review of computerized medical records excluding free-text comments; manual review including free-text comments (which include information gained from specialists, hospital discharge letters and results of diagnostic tests) of a random sample of possible cases (n = 300) and non-cases (n = 100); and review of full medical records of this random sample and a questionnaire completed by their primary care physician. The positive predictive value (PPV) of each step was calculated. The confirmation rate was used to estimate incidence in the general population. RESULTS After step 1, 3447 individuals were classified as possible cases and 792 were excluded as non-cases. After step 2, 82% of possible cases were still classified as such. Step 3 showed that inclusion of free-text comments increased the PPV of a diagnosis from 76 to 86%. The weighted incidence of hospitalized ischemic cerebrovascular events was 1.73 per 1000 person-years (95% CI:1.68-1.77). CONCLUSIONS THIN demonstrates a high validity for the study of ischemic cerebrovascular events when reviewing computer records with additional free-text comments. Accuracy of hospitalization status was not as well recorded.

Abstract
Patent foramen ovale is found in 24% of healthy adults and 38% of patients with cryptogenic stroke. This ratio and case reports indicate that patent foramen ovale and stroke are associated, probably because of paradoxical embolism. In healthy people with patent foramen ovale, embolic events are not more frequent than in controls, and therefore no primary prevention is needed. However, once ischaemic events occur, the risk of recurrence is substantial and prevention becomes an issue. Acetylsalicylic acid and warfarin reduce this risk to the same level as in patients without patent foramen ovale. Patent foramen ovale with a coinciding atrial septal aneurysm, spontaneous or large right-to-left shunt, or multiple ischaemic events potentiates the risk of recurrence. Transcatheter device closure has therefore become an intriguing addition to medical treatment, but its therapeutic value still needs to be confirmed by randomised-controlled trials.

Abstract
Patients with giant cell arteritis (GCA) generally present with cranial ischemic manifestations that are directly related to vascular involvement. They may also experience strokes in the territory of the carotid or the vertebrobasilar artery. We conducted the current study to assess the frequency and predictors of strokes in general, and of vertebrobasilar stroke in particular, at the time of diagnosis in a series of 287 consecutive patients with biopsy-proven GCA diagnosed over a 27-year period at the single hospital for a well-defined population of northwestern Spain.During the study period, 8 (2.8%) patients had strokes (1 in the carotid and 7 in the vertebrobasilar territory) between the onset of symptoms of the disease and 4 weeks after the onset of corticosteroid therapy. Six of the 7 patients with vertebrobasilar stroke were men. In most cases the vertebrobasilar stroke occurred after the onset of corticosteroid therapy. Smoking history was more common among patients with vertebrobasilar stroke (p = 0.01). Patients with vertebrobasilar stroke more commonly had permanent visual loss due to arteritic involvement of ophthalmic branches derived from the internal carotid (3/7; 42.9%) than the rest of GCA patients (33/280; 11.8%) (p = 0.05). Patients with strokes had higher hemoglobin values (13.2 +/- 1.5 g/dL) than patients without (11.7 +/- 1.6 g/dL) (p = 0.009). Moreover, only 1 (14.3%) of the 7 patients with vertebrobasilar stroke had anemia compared to 157 (56.1%) of the remaining 280 patients (p = 0.05). The best predictors of stroke were permanent visual loss (odds ratio [OR], 5.42) and arterial hypertension (OR, 5.06). In contrast, women (OR, 0.10) and patients with anemia at the time of disease diagnosis (OR, 0.11) had a significantly reduced risk of suffering strokes. Smoking history was the best positive predictor of vertebrobasilar stroke (OR, 5.22). In contrast, a reduced risk of suffering vertebrobasilar strokes was found in individuals who had anemia at the time of GCA diagnosis (OR, 0.13).Results of the current study show an increased risk of strokes, in the vertebrobasilar territory in particular, at the time of GCA diagnosis. Patients with biopsy-proven GCA and traditional cardiovascular risk factors or permanent visual loss have an increased risk of suffering strokes. Results also suggest a potential protective role of anemia against the development of these cerebrovascular complications.
