RESUMO
BACKGROUND: White matter hyperintensities (WMH) are the result of cerebral small vessel disease and may increase the risk of cognitive impairment (CI), recurrent stroke, and depression. We aimed to explore the association between selected cerebrovascular risk factors (CVRF) and WMH load as well as the effect of increased WMH burden on recurrent vascular events, CI, and depression in first-ever ischemic stroke patients. METHODS: 431 from the PROSpective Cohort with Incident Stroke (PROSCIS) were included; Age-Related White Matter Changes (ARWMC) score was used to assess WMH burden on FLAIR. The presence of CVRF (defined via blood pressure, body-mass-index, and serological markers of kidney dysfunction, diabetes mellitus, and hyperlipoproteinemia) was categorized into normal, borderline, and pathological profiles based on commonly used clinical definitions. The primary outcomes included recurrent vascular events (combined endpoint of recurrent stroke, myocardial infarction and/or death), CI 3 years post-stroke, and depression 1-year post-stroke. RESULTS: There was no clear association between CVRF profiles and WMH burden. High WMH lesion load (ARWMC score ≥ 10) was found to be associated with CI (adjusted OR 1.05 [95% CI 1.00-1.11]; p < 0.02) in a mixed-model analysis. Kaplan-Meier survival analysis showed a visible increase in the risk of recurrent vascular events following stroke; however, after adjustment, the risk was non-significant (HR 1.5 [95% CI 0.76-3]; p = 0.18). WMH burden was not associated with depression 1-year post stroke (adjusted OR 0.72 [95% CI 0.31-1.64]; p = 0.44). CONCLUSION: Higher WMH burden was associated with a significant decline in cognition 3 years post-stroke in this cohort of first-ever stroke patients.

To investigate the time-dependent effects of traditional risk factors on functional disability in all-cause mortality post-stroke, we evaluated data from a long-term stroke cohort. Baseline cerebrovascular risk factors (CVRF) and functionality at 1 and 6 months were evaluated in survivors from a prospective stroke cohort using the modified Rankin scale (m-RS), which classifies participants as improvement of disability, unchanged disability (at least moderate), and worsening disability. Cox regression models considering baseline risk factors, medication use, and functionality 6 months after stroke were fitted to identify their time-dependent effects up to 12 years of follow-up. Adjusted hazard ratios (HR) with 95% confidence intervals (CI) are presented. Among 632 survivors (median age 68, 54% male, 71% first-ever episode), age and functional disability (unchanged and worsening) 6 months after ischemic stroke had time-dependent effects on all-cause mortality risk up to 12 years of follow-up. The most impacting risk factors were unchanged (at least moderate) (HR, 2.99; 95%CI: 1.98-4.52) and worsening disability (HR, 2.85; 95%CI: 1.26-6.44), particularly in the first two years after a stroke event (Time 1: ≥6 mo to <2.5 y). Worsening disability also impacted mortality in the period from ≥2.5 to <7.5 years (Time 2) of follow-up (HR, 2.43 (95%CI: 1.03-5.73). Other baseline factors had a fixed high-risk effect on mortality during follow-up. Post-stroke and continuous medication use had a fixed protective effect on mortality. Functional disability was the main contributor with differential risks of mortality up to 12 years of follow-up.
RESUMO
INTRODUCTION: The level of collateral compensation plays a pivotal role in chronic symptomatic intracranial vertebrobasilar stenosis (IVBS). This study aimed to evaluate the association between cerebrovascular risk factors and collateral compensation in chronic symptomatic IVBS. METHODS: This single-center cross-sectional study retrospectively reviewed 238 patients with angiographically demonstrated IVBS and divided them into good collateral compensation (GCC) group (collateral grade: 3-4, n = 110) and poor collateral compensation (PCC) group (collateral grade: 0-2, n = 128). The demographic information, laboratory tests, and clinical data of the two groups were compared and assessed using univariate logistic regression. Multivariate logistic regression was employed to analyze the independent related factors of collateral compensation. RESULTS: Hyperlipidemia, high-density lipoprotein (HDL), and fasting blood glucose (FBG) were significantly different between the two groups. Multivariate logistic regression analysis revealed that HDL (odds ratio [OR]: 1.134, 95% confidence interval [CI]: 1.081-1.190), FBG (OR: 0.945, 95% CI: 0.925-0.964), and hyperlipidemia (OR: 0.261, 95% CI: 0.129-0.527) were statistically independent related factors of collateral compensation. The receiver-operating characteristic (ROC) analysis provided cutoff values of 34 mg/dL and 135 mg/dL for HDL and FBG associated with GCC and PCC. CONCLUSION: Higher HDL levels are associated with higher incidence of GCC, whereas higher FBG levels and hyperlipidemia are associated with higher incidence of PCC.

Alzheimer's disease (AD) has been associated with cardiovascular and cerebrovascular risk factors (CVRFs) during middle age and later and is frequently accompanied by cerebrovascular pathology at death. An interaction between CVRFs and genetic variants might explain the pathogenesis. Genome-wide, gene by CVRF interaction analyses for AD, in 6568 patients and 8101 controls identified FMNL2 (p = 6.6 × 10-7). A significant increase in FMNL2 expression was observed in the brains of patients with brain infarcts and AD pathology and was associated with amyloid and phosphorylated tau deposition. FMNL2 was also prominent in astroglia in AD among those with cerebrovascular pathology. Amyloid toxicity in zebrafish increased fmnl2a expression in astroglia with detachment of astroglial end feet from blood vessels. Knockdown of fmnl2a prevented gliovascular remodeling, reduced microglial activity and enhanced amyloidosis. APP/PS1dE9 AD mice also displayed increased Fmnl2 expression and reduced the gliovascular contacts independent of the gliotic response. Based on this work, we propose that FMNL2 regulates pathology-dependent plasticity of the blood-brain-barrier by controlling gliovascular interactions and stimulating the clearance of extracellular aggregates. Therefore, in AD cerebrovascular risk factors promote cerebrovascular pathology which in turn, interacts with FMNL2 altering the normal astroglial-vascular mechanisms underlying the clearance of amyloid and tau increasing their deposition in brain.

OBJECTIVE: Recent studies have examined retinal vascular abnormalities in schizophrenia as retinal vascular imaging is a non-invasive proxy to cerebral microvasculature. However, relation between retinal vascular abnormalities and brain structure is not well examined in schizophrenia. Hence in this study, for the first time, we examined the relationship between retinal vascular measures and brain white matter lesions in schizophrenia. We examined brain white matter lesions as they are considered a predictive marker for future adverse cerebrovascular event. METHODS: We acquired retinal vascular images of both eyes using a non-mydriatic camera and calculated retinal vascular diameter, tortuosity, trajectory and fractal dimension using validated methods. All patients underwent Magnetic Resonance Imaging of bran and we computed white matter hypo-intensities using Freesurfer software. We performed a linear regression analysis to examine the relationship between white matter hypo-intensities and retinal vascular measures controlling for age, sex, fasting blood sugar, creatinine, whole-brain volume, and antipsychotic dose. RESULTS: The regression model was significant in Schizophrenia patients (R=0.983;R2 =0.966;-F=10.849;p = 0.008) but not in healthy volunteers (R=0.828;R2 =0.686;F=0.182; p = 0.963). Among the retinal vascular measures, arterial tortuosity (ß = 0.963;p-0.002), tortuosity (ß = -1.002;p = 0.001) and fractal dimension (ß = -0.688;p = 0.014) were significant predictors of white matter lesions. DISCUSSION: The current study's findings support the conclusion that retinal vascular fractal dimension and tortuosity are associated with changes in cerebral white matter and may be considered proxy markers for cerebral microvasculature in schizophrenia. Considering the relationship between white matter lesions and stroke, these observations could have important clinical implications to screen schizophrenia patients for risk of adverse cerebrovascular event.

INTRODUCTION: In a multicentre study, we contrasted cerebrovascular disease profiles in Pacific Island (PI)-born patients (Indigenous Polynesian [IP] or Indo-Fijian [IF]) presenting with transient ischaemic attack (TIA), ischaemic stroke (IS) or intracerebral haemorrhage (ICH) with those of Caucasians (CSs). METHODS: Using a retrospective case-control design, we compared PI-born patients with age- and gender-matched CS controls. Consecutive patients were admitted to 3 centres in South Western Sydney (July 2013-June 2020). Demographic and clinical data studied included vascular risk factors, stroke subtypes, and imaging characteristics. RESULTS: There were 340 CS, 183 (27%) IP, and 157 (23%) IF patients; mean age 65 years; and 302 (44.4%) female. Of these, 587 and patients presented with TIA/IS and 93 (13.6%) had ICH. Both IP and IF patients were significantly more likely to present >24 h from symptom onset (odds ratios [ORs] vs. CS 1.87 and 2.23). IP patients more commonly had body mass indexes >30 (OR 1.94). Current smoking and excess alcohol intake were higher in CS. Hypertension, diabetes, and chronic kidney disease were significantly higher in both IP and IF groups in comparison to CS. IP patients had higher rates of AF and those with known AF were more commonly undertreated than both IF and CS patients (OR 2.24, p = 0.007). ICH was more common in IP patients (OR 2.32, p = 0.005), while more IF patients had intracranial arterial disease (OR 5.10, p < 0.001). DISCUSSION/CONCLUSION: Distinct cerebrovascular disease profiles are identifiable in PI-born patients who present with TIA or stroke symptoms in Australia. These may be used in the future to direct targeted approaches to stroke prevention and care in culturally and linguistically diverse populations.

Cerebral ischemia is a major health problem worldwide, that affects millions of people, leaving a major percentage of them with major disabilities, therefore becoming one of the most resource consuming pathology. Beside the blockage of blood supply of the brain that leads to loss of cellular function and neuronal necrosis, metabolic processes are modified in the whole body through mechanisms that are not fully explained yet. The results in the analysis of the 2 groups, one with 70 patients with stroke and another with 68 patients with no cerebral infarction, revealed that brain ischemia is more often found in patients with atrial fibrillation and higher blood pressure values. The metabolic changes, found in the stroke group, are represented by increased values of blood glucose, serum urea and lower levels of creatinine levels. Also, the value of leucocytes count and the erythrocyte sedimentation rate were shown to be increased in stroke patients, indicating that inflammation is highly present in cerebral infarction. In the regard of these findings, cerebral ischemia is associated with major systemic disruptions that could be significant pathogenic factors and also effects of the complex processes that take place in the affected brain region, but further investigation should be done in order to explain all the mechanisms involved and also the possible impact in prophylaxis and acute management of stroke.
RESUMO
BACKGROUND: Neuropsychiatric symptoms (NPS) may represent early clinical manifestations of evolving brain diseases. Studies underpin the occurrence of NPS in the context of mild cognitive impairment (MCI) and prodromal Alzheimer's disease, where symptoms referred to as 'mild behavioural impairment' (MBI) have been shown to predict conversion to dementia and to hasten cognitive/functional decline. However, the association between NPS and cerebrovascular risk factors has been poorly investigated, despite the high prevalence of the latter among individuals with MCI. The aim of the present study was to investigate the association between MBI and cerebrovascular risk in a clinical sample of non-demented elders. METHODS: Sixty-five MCI and 15 cognitively unimpaired older adults were cross-sectionally assessed with the Mild Behavioural Impairment Checklist (MBI-C), using the cut-off score > 6.5 to define positive screening. Participants were submitted to the Hachinski Ischaemic Score (HIS) to account for cerebrovascular symptoms, vascular risk, and related comorbidities. Neuroimaging scans (magnetic resonance imaging and/or 18F-fluorodeoxyglucose-positron emission tomography) and apolipoprotein E genotype were obtained. RESULTS: Positive associations were found between total MBI-C scores and increasing number of comorbidities present (0-2 comorbidities), but not with three comorbidities. Two domains of the MBI-C-impulse dyscontrol and social inappropriateness-followed the same trend of the MBI-C total score, with higher scores with the increasing numbers of comorbidities. No significant associations were found between MBI symptoms and HIS or cerebrovascular burden in neuroimaging assessment. CONCLUSION: We found weak associations between MBI-C total score and the presence of comorbidities with cerebrovascular risk, but not with structural or functional neuroimaging abnormalities or HIS. This finding may represent that the presence of comorbidities adds limited risk to the occurrence of MBI in this sample of non-demented elders.

BACKGROUND: Non-high-density lipoprotein cholesterol (non-HDL-C) may be an independent risk factor for cardio-cerebrovascular disease (CVD); however, the cutoff level in patients on maintenance hemodialysis (MHD) is unknown. METHODS: This was a retrospective multicenter study of MHD patients treated at 10 dialysis centers in Guangdong Province from July 1, 2016, to April 1, 2017. Laboratory test data were collected and CVD complications and outcomes recorded. RESULTS: In total, 1288 eligible patients were included in this study; the non-HDL-C interquartile range was 2.76 (2.24-3.45) mmol/L. Over a median follow-up time of 24 months, 141 patients developed CVD. The non-HDL-C level was a principal risk factor for such events (P < 0.05; 95% confidence interval 0.800-0.842). The maximum Youden index was 0.549 and the best cutoff > 3.39 mmol/L. CONCLUSION: Higher baseline non-HDL-C levels may increase the CVD risk in MHD patients. Thus, non-HDL-C effectively predicts CVD.

BACKGROUND AND AIMS: The aims of this study were to identify dietary patterns in a general population of North Italian adults and to investigate the cross-sectional association between prevalent dietary patterns and arterial stiffness. METHODS AND RESULTS: Participants to the RoCAV study without chronic diseases at recruitment and with reliable dietary data were included. The food-frequency EPIC questionnaire was used to evaluate dietary habits. Dietary patterns were estimated using principal components analysis and Mediterranean diet adherence score (MedS). Carotid-femoral pulse wave velocity (cfPWV) was used as proxy of arterial stiffness. Basing on data from 2640 subjects (1608 men and 1032 women, mean ± SD 65.5 ± 6.7 years), four principal components (PC) were retained, explaining 24% of the overall variance. Considering 1284 subjects with cfPWV (mean ± SD 10.7 ± 2.5 m/s) data available, adherence to PC1 (Western-like dietary pattern) was associated with higher stiffness values (+0.29 m/s cfPWV for 1 SD increase of PC1, 95% CI:0.08,0.50; p = 0.007) in a multivariate model. Conversely, adherence to PC2 (Mediterranean-like) was not related to cfPWV values (-0.18, 95% CI: -0.36, 0.004; p = 0.06). Likewise, MedS and other PC patterns did not show any significant association with cfPWV. Mediation analysis showed that the association between Western-like dietary pattern and cfPWV is mediated by higher levels of leucocytes (9.2% of the effect, p = 0.047). CONCLUSIONS: Our study in a Southern European population identified a Western-like dietary pattern associated with an increased cfPWV, a proxy of arterial stiffness. The association with cfPWV was in part mediated by inflammatory status.

Background: The smoking-thrombolysis paradox refers to a better outcome in smokers who suffer from acute ischemic stroke (AIS) following treatment with thrombolysis. However, studies on this subject have yielded contradictory results and an interaction analysis of exposure to smoking and thrombolysis in a large, multicenter database is lacking. Methods: Consecutive AIS patients admitted within 12 h of symptom onset between 2009 and 2014 from the prospective, multicenter stroke registry (Dutch String-of-Pearls Stroke Study) were included for this analysis. We performed a generalized linear model for functional outcome 3 months post-stroke depending on risk of the exposure variables (smoking yes/no, thrombolysis yes/no). The following confounders were adjusted for: age, smoking, hypertension, atrial fibrillation, diabetes mellitus, stroke severity, and stroke etiology. Results: Out of 468 patients, 30.6% (N = 143) were smokers and median baseline NIHSS was 3 (interquartile range 1-6). Smoking alone had a crude and adjusted relative risk (RR) of 0.99 (95% CI 0.89-1.10) and 0.96 (95% CI 0.86-1.01) for good outcome (modified Rankin Score ≤ 2), respectively. A combination of exposure variables (smoking and thrombolysis) did not change the results significantly [crude RR 0.87 (95% CI 0.74-1.03], adjusted RR 1.1 (95%CI 0.90-1.30)]. Smoking alone had an adjusted RR of 1.2 (95% CI 0.6-2.7) for recanalization following thrombolysis (N = 88). Conclusions: In patients with mild to moderate AIS admitted within 12 h of symptom onset, smoking did not modify treatment effect of thrombolysis.
RESUMO
Background and purpose: The aggregation of vascular risk factors (VRFs) can aggravate cognitive impairment in stroke-free patients. Metabolites in serum and cerebrospinal fluid (CSF) may irreversibly reflect early functional deterioration. This study evaluated small-molecule metabolites (<1,000 Da) in the serum and CSF of patients with different degrees of cerebrovascular burden and investigated the correlation between metabolism and cognitive performance associated with VRFs. Methods: The subjects were divided into a low-risk group (10-year stroke risk ≤ 5%), a middle-risk group (10-year stroke risk >5% and <15%), and a high-risk group (10 years stroke risk ≥ 15%) according to the Framingham stroke risk profile (FSRP) score, which was used to quantify VRFs. We assess the cognitive function of the participants. We semiquantitatively quantified the small molecules using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The correlation between the small molecules and cognitive function, along with VRFs, was investigated to identify key small molecules and possible underlying metabolic pathways. Results: When the FSRP scores increased, the cognitive performances of the subjects decreased, specifically the performance regarding the tasks of immediate memory, delayed recall, and executive function. Seven metabolites (2-aminobutyric acid, Asp Asp Ser, Asp Thr Arg, Ile Cys Arg, 1-methyluric acid, 3-tert-butyladipic acid, and 5α-dihydrotestosterone glucuronide) in serum and three metabolites [Asp His, 13-HOTrE(r), and 2,5-di-tert-Butylhydroquinone] in CSF were significantly increased, and one metabolite (arachidonoyl PAF C-16) in serum was significantly decreased in high-risk group subjects. Among these metabolites, 1-methyluric acid, 3-tert-butyladipic, acid and Ile Cys Arg in serum and 13-HOTrE(r), 2,5-di-tert-butylhydroquinone, and Asp His in CSF were found to be negatively related with cognitive performance in the high-risk group. Arachidonoyl PAF C-16 in serum was found to be associated with better cognitive performance. Caffeine metabolism and the tricarboxylic acid cycle (TCA cycle) were identified as key pathways. Conclusions: 1-Methyluric acid, 3-tert-butyladipic acid, arachidonoyl PAF C-16, and Ile Cys Arg in serum and 13-HOTrE(r), 2,5-di-tert-butylhydroquinone, and Asp His in CSF were identified as potential biomarkers of vascular cognitive impairment (VCI) at the early stage. Caffeine metabolism and the TCA cycle may play important roles in the pathophysiology of VRF-associated cognitive impairment.
RESUMO
Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo, especially in the elderly. Several studies have revealed a possible seasonality to BPPV. However, whether the seasonality of BPPV also exists in China is unclear. The characteristics of cardio-cerebrovascular risk factors for BPPV in the cold season have not yet been investigated. Objectives: (1) To investigate the seasonality of BPPV; (2) To explore the relationship between cardio-cerebrovascular risk factors and seasonality of BPPV. Methods: A retrospective observational study was performed in Beijing Tiantan Hospital from Jan 2016 to Dec 2018. The study included 1,409 new-onset BPPV patients aged 18-88 years. The demographic data, onset time, and medical history of BPPV were collected. The meteorological data, including temperature, atmospheric pressure, rainfall, and insolation, was obtained from Beijing Meteorological service. The x 2 goodness of fit test was used to evaluate whether BPPV patients' numbers were significantly different among different months of the year. The Spearman correlation was used to detect the correlation between numbers of BPPV patients diagnosed monthly with each climatic parameter. The chi-square test for linear-by-linear association were used to investigate the relationship between cardio-cerebrovascular risk factor and seasonality of BPPV. Results: November to next March is the top 5 months with higher BPPV patient numbers (P < 0.001). The numbers of BPPV diagnosed monthly were conversely correlated with temperature and rainfall (r = -0.736, P = 0.010; r = -0.650, P = 0.022, respectively), positively correlated with atmospheric pressure (r = 0.708, P = 0.010), but no significant correlated with insolation. BPPV in the cold season (including January, February, March, November, and December) had a higher proportion, accounting for 54.2% of all BPPV patients. Among BPPV patients with ≥2, 1, and none cardio-cerebrovascular risk factors, the cold season accounted for 57.0, 56.0, 49.8%, respectively. As the number of cardio-cerebrovascular risk factors increased, the proportion of patients in the cold season of BPPV increased (P = 0.025). Conclusions: BPPV patients are seen more in the months with low temperature, low rainfall, and high atmospheric pressure. Compared with the non-cold season, BPPV patients have more risk factors for cardio-cerebrovascular diseases in the cold season.
RESUMO
Objective: This study aimed to investigate the serum level of homocysteine in menopausal women and to explore the association between menopausal status, blood lipids, and homocysteine concentrations.Methods: The study recruited females aged 40-60 years who were not receiving menopausal hormone therapy. The demographic characteristics and menopausal status of the women were collected in the form of questionnaires. The study analyzed the association between hyperhomocysteinemia and variables using binary logistic stepwise regression.Results: Among 366 enrolled subjects, menopausal status was divided into four stages: premenopause stage (n = 135), menopausal transition stage (n = 91), early postmenopause stage (n = 87), and late postmenopause stage (n = 53). The proportion of hyperhomocysteinemia in the premenopausal stage, menopausal transition stage, and postmenopausal stage was 43%, 26.4%, and 45%, respectively (χ2 = 8.999, p = 0.011). The mean concentration of homocysteine was 9.75 µmol/l. The level of homocysteine was higher in the postmenopause stage than in the other stages (p = 0.043), and the difference between postmenopause and menopausal transition was statistically significant (p < 0.01). In the binary logic analysis, menopausal transition compared with postmenopause (odds ratio = 2.027, 95% confidence interval = 1.117-3.679, p = 0.005).Conclusions: Serum homocysteine levels are associated with menopausal status. Homocysteine concentrations were progressively higher across menopausal stages. The transformation in the female body across the menopause transition stages may cause elevations in the homocysteine level in postmenopausal women.

Benign paroxysmal positional vertigo (BPPV) manifests itself as a paroxysm of vertigo and nystagmus lasting several seconds, which is self-limiting. The clinical characteristics and risk factors for the recurrence of BPPV in different ages have not yet been investigated. Materials and Methods: A retrospective observational study was conducted in the Department of Neurology in Beijing Tiantan Hospital from July 2009 to June 2015. The study included 1,012 patients aged 18-93 years. All patients received the definitive diagnosis and canalith repositioning maneuvers treatment and finally accomplished follow-up. Demographic variables, potential recurrence risk factors, neurological examination, and laboratory indexes were assessed. Data Analyses: The t-test or chi-squared test was first performed for group comparison, then logistic regression analysis was used to investigate the risk factors of BPPV recurrence. Results: The 1-year recurrence rates of BPPV patients after reposition maneuvers were, respectively, 22.79% (aged 18-45 years), 23.92% (aged 45-60 years), 28.89% (over 60 years). The recurrence rates among the three groups have no statistically significant difference. Logistic regression analysis shows that women BPPV patients have more recurrence risks than do men. Ménière's disease (odds ratio = 6.009, 95% confidence interval: 2.489-14.507, p < 0.001), hypertension (odds ratio = 1.510, 95% confidence interval: 1.095-2.084, p = 0.012), migraine (odds ratio = 2.534, 95% confidence interval: 1.164-5.516, p = 0.019), and hyperlipemia (odds ratio = 1.419, 95% confidence interval: 1.024-1.968, p = 0.036) were risk factors for the recurrence of BPPV in patients. Conclusion: We conclude that Ménière's disease, hypertension, migraine, and hyperlipemia may be independent risk factors for the recurrence of BPPV in patients, but aging does not increase the recurrence risk.
RESUMO
PURPOSE OF REVIEW: This review aims to support obstructive sleep apnea (OSA) as a risk factor for ischemic stroke, review treatment strategies for OSA, provide a comprehensive review of clinical data on OSA treatment and ischemic stroke risk, and to critically assess if treatment of OSA decreases the risk of ischemic stroke and if treatment improves outcomes and subsequent ischemic stroke risk in post-stroke patients. RECENT FINDINGS: Several observational studies, randomized controlled trials (RCTs), and meta-analyses have examined the risk of ischemic stroke and cardiovascular events in patients with OSA and have also examined continuous positive airway pressure (CPAP) treatment in these patients. Observational studies have shown an increased risk of ischemic stroke in patients with untreated OSA when compared with patients treated with CPAP; however, results are not statistically significant. RCTs and meta-analyses have shown no significant ischemic stroke risk reduction in CPAP treated patients with OSA. Several studies have shown improved outcomes in post-stroke patients with OSA treated with CPAP; however, few data is available for subsequent ischemic stroke risk reduction. Further research is needed for surgical treatment of OSA and assessment of ischemic stroke risk. OSA is associated with increased risk of ischemic stroke, and OSA should be treated with the appropriate therapy. While the current data is promising, more studies are necessary to state whether treatment of OSA reduces ischemic stroke risk and subsequent ischemic stroke risk. A practical approach to the sleep disorder evaluation and treatment of patients with cerebrovascular disease is outlined.
RESUMO
WHAT IS KNOWN AND OBJECTIVE: In the last decades, many lists have been developed to screen for inappropriate prescribing. However, information on which potentially inappropriate medications (PIMs) could increase the cardiovascular risk in the elderly is not objectively presented. This review aimed to identify and quantify those PIMs by extracting information from published PIM-lists. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA), a systematic review of PIM-lists was conducted. The search strategy was run in PubMed, MEDLINE and Google Scholar (1991-09/2017). All PIMs described in those lists were extracted and stratified by their potential cardiovascular risk (including major adverse cardiovascular events-MACE). The number of times each PIM was reported on those lists was also assessed. RESULTS AND DISCUSSION: We identified 724 papers, and 24 were retained. From those, a total of 17 PIMs to be avoided by the elderly and 21 drug-disease interactions were retrieved. The reporting of PIMs with risk of cardiovascular adverse events was 15.3%, whereas the reporting of those with MACE risk was 7.2%. PIMs most frequently described were tricyclic antidepressants (TCAs; 12/24), centrally acting antiadrenergic agents (11/24), NSAIDs (7/24), antiarrhythmics (Class I and III; 6/24), peripherally acting antiadrenergic agents (6/24) and antithrombotic agents (5/24). Most frequently described PIMs with MACE risk were NSAIDs (7/24), antiarrhythmics (Class I and III) (7/24), selective calcium channel blockers with vascular effects (6/24) and antipsychotics (4/24). WHAT IS NEW AND CONCLUSION: Data suggest that PIM-lists focus mainly on common adverse events and often poorly describe the potential consequence for MACE occurrence. This systematic review could help healthcare professionals in the identification and deprescribing of these medicines in older patients with high cardiovascular risk during medication review.

BACKGROUND: Statins are prescribed for patients with cardiovascular disease (CVD), along with the recommendation of adopting healthy diets. We evaluated the independent and the combined effect of statins and Mediterranean diet (MD) towards mortality risk in patients with previous CVD by using real-life data from a population-based prospective cohort. METHODS: Longitudinal analysis on 1180 subjects (mean age 67.7⯱â¯10) with prior CVD at enrollment in the Moli-sani Study and followed up for 7.9â¯y (median). Adherence to MD was appraised by a Mediterranean diet score. Hazard ratios (HR) with 95% confidence intervals (95% CI) were calculated by multivariable Cox regression and competing risk models. RESULTS: Multivariable risk estimates associated with a 2-point increase in MD score were 0.84 (95% CI 0.70-1.00), 0.77 (0.61-0.97) and 0.70 (0.52-0.93) for overall, cardiovascular and coronary artery disease (CAD)/cerebrovascular deaths, respectively. Statins were not associated with death risk. Subjects combining statins and average-high adherence to MD had much lower than expected risk of cardiovascular and CAD/cerebrovascular mortality (p for interactionâ¯=â¯0.045 and 0.0015, respectively) as compared to those neither using statins nor having average-high MD. The combination of average-high MD and statins was associated in a likely synergistic way with reduced low-grade inflammation, but not with blood cholesterol. CONCLUSIONS: MD lowered the risk of all-cause, cardiovascular and CAD/cerebrovascular mortality CVD patients, net of statins. In the same population, statins reduced CVD death risk only in combination with MD. Low-grade inflammation, rather than lipids, is likely to be on the pathway of the interaction between MD and statins towards mortality risk.

INTRODUCTION: Preeclampsia is a pregnancy-related hypertensive disorder with strongly impaired cerebral autoregulation in the acute stage. A history of preeclampsia is an independent cardiovascular and cerebrovascular risk factor. It is unclear whether impaired cerebral autoregulation persists after preeclampsia and thus contributes to the known increased cerebrovascular morbidity. METHODS: Using transcranial Doppler, we compared cerebral hemodynamics and dynamic cerebral autoregulation of 25 women with a history of severe preeclampsia and 25 healthy mothers, on average 2-3â¯years postpartum. Mean arterial blood pressure (MAP) and cerebral blood flow velocities (CBFV) in the middle and posterior cerebral artery were recorded at rest, dynamic cerebral autoregulation was assessed via transfer function phase and gain between oscillations of CBFV and MAP during regular breathing at 0.1â¯Hz. RESULTS: MAP and body mass index were higher in former preeclamptic women compared with healthy mothers (p-value <0.001 and 0.006, respectively). CBFV in the middle cerebral artery was slightly increased in former preeclamptic women compared with healthy mothers (p-value 0.004), intima-media thickness (IMT) of the common carotid artery was higher by trend (p-value 0.065). Dynamic cerebral autoregulation was not impaired in women with a history of preeclampsia, phase even tended to be higher than in healthy mothers. CONCLUSION: Dynamic cerebral autoregulation is not persistently impaired in women after severe preeclampsia. Long-term cerebrovascular changes rather result from a higher incidence of cerebrovascular risk factors in women with a history of preeclampsia.

PURPOSE: To investigate the relationship between cerebrovascular risk factors, including carotid plaques, and vestibular neuritis (VN). MATERIALS AND METHODS: According to the inclusion and exclusion criteria, this retrospective study included 90 VN patients and 74 age- and sex-matched healthy controls from January 2016 to December 2017. All subjects' records of cerebrovascular risk factors, such as age, sex, height, weight, history of hypertension and diabetes mellitus, living habits, serum levels of glucose, lipids, glycosylated haemoglobin (HbA1c), creatinine (CR), albumin (ALB), haemoglobin (HGB); and results of carotid colour Doppler ultrasound, were obtained and compared. RESULTS: No significant differences in age; sex ratio; body mass index; history of hypertension or diabetes mellitus; or mean serum lipids, glucose, creatinine, haemoglobin or HbA1c were found between patients with VN and healthy controls (all Pâ¯>â¯0.05). The mean serum ALB level was significantly lower in VN patients than in healthy controls (40.65⯱â¯3.77 vs 42.84⯱â¯4.32, Pâ¯=â¯0.001).The prevalence of carotid plaques was significantly higher in VN patients than in healthy controls (36.67% vs. 16.22%, Pâ¯=â¯0.003). Regression analyses demonstrated that a high frequency of carotid plaques was associated with VN with an odds ratio of 2.252 (95% CI 1.165-5.458, Pâ¯=â¯0.019). CONCLUSION: A high frequency of carotid plaques may be a risk factor for VN.
