Objectives The detection of cervical arterial dissection (CAD) has been rising in recent years owing to advanced imaging techniques. The aim of this study was to explore whether wide implementation of endovascular treatment for ischemic stroke has an impact on the diagnosis of CAD. Methods We included all patients with CAD diagnosed at two university hospitals in Seville, Spain from January 2015 to December 2017. We collected clinical variables and information on imaging techniques used for the diagnosis. Implementation of 24 hour/365 day mechanical thrombectomy began in Seville on 15 August 2016. We compared diagnosis rates of CAD performed before and after this date. Results We identified 41 patients with CAD. We found 13 patients diagnosed before (1.1% of all ischemic strokes) and 28 (2.2%) after implementation of neurointerventional therapy. In 17 patients, diagnosis was made in the acute phase. Dissection was not suspected according to computed tomography angiography in 11 patients owing to small dissections (n = 2) or total occlusion (n = 9). Conclusions CAD diagnoses have been rising in recent years, essentially owing to continuous improvement in imaging techniques. Rapid access to arteriography for thrombectomy is increasing the diagnoses of CAD, even in patients with a low suspicion of dissection.

Background and Aims: The benefits of Mediterranean Diet (MeDiet) in prevention of cardiovascular diseases (CVD) in general and ischemic stroke (IS) have been extensively studied and reported. We hypothesize that the consumption of nutrients typical of MeDiet would also reduce the rate of silent brain infarcts (SBI) among AF patients. Methods and Results: Patients with a history of AF who scored 0 to 1 in the CHADS2 score, ⩾50 years and with absence of neurological symptoms were selected from Seville urban area using the Andalusian electronic healthcare database. A 3T brain MRI was performed to all participants. Demographic and clinical data and food-frequency questionnaire (FFQ) were collected. Of the 443 scanned patients, 66 presented SBI. Of them 52 accepted to be scheduled for a clinical visit and were included in the diet sub study and 41 controls were matched per age and sex. There were no statistically significant differences in baseline characteristics. After logistic regression analysis, we found that a higher consumption of fiber from fruit was independently associated with a lower risk of SBI, while a higher consumption of high glycemic load (GL) foods was associated with a higher risk of SBI in a population with AF Conclusion: Our findings support that MeDiet could be suggested as a prevention strategy for SBI in patients with AF.

Background Silent brain infarcts (SBI), a finding on neuroimaging, are associated with higher risk of future stroke. Atrial Fibrillation (AF) has been previously identified as a cause of SBI. Objectives The aim of this study is to determine the prevalence of and risk factors for SBI in patients with AF and low-to-moderate embolic risk according to CHADS 2 and CHA 2 DS 2 VASc score. Methods Patients with a history of AF based on medical records who scored 0–1 in the CHADS 2 score were selected from the Seville urban area using the Andalusian electronic healthcare database (DIRAYA). Demographic and clinical data were collected and a 3T brain MRI was performed on patients older than 50 years and with absence of neurological symptoms. Results 66 of the initial 443 patients (14.9%) and 41 of the 349 patients with low risk according to CHA 2 DS 2 VASc score (11.7%) presented at least 1 SBI. After adjusted multivariable analysis, an older age (OR 3.84, 95% CI 1.07–13.76) and left atrial (LA) enlargement (OR 3.13, 95% CI 1.15–8.55) were associated with SBI in the whole cohort, while only LA enlargement was associated with SBI in the low-risk cohort (OR 3.19, 95% CI 1.33–7.63). Conclusions LA enlargement on echocardiogram was associated with SBI in patients with AF and low or moderate embolic risk according to CHADS 2 and in the low-risk population according to CHA 2 DS 2 VASc. Although further studies are needed, a neuroimaging screening might be justified in these patients to guide medical therapies to improve stroke prevention.

The individuals belonging to three different groups of wild grapevines populations Vitis vinifera L. ssp. sylvestris (Gmelin) Hegi harvested along, or near the Danube River, were described by means of usual ampelographic methods. The twenty standardized descriptors used for morphological analysis revealed obvious differentiation among analyzed populations. Out of 65 individuals, a half produced flowers with separate sex and a high proportion of them were males (70%). Pollen measurements on light microscope provided information on differences in pollen size among inside wild grapevine populations of V. sylvestris with the polar length varying between 15.3 and 23 μm and the equatorial length between 15.5 and 24.4μm. The in vitro regenerative potential from meristematic tissue tested with each phenotype showed that the moment of differentiation, the aspect of proliferative structures and the rate of multiplication varied inside these wild grapevine populations, without any correlation with the location of harvesting. Our results provided valuable information about these Vitis vinifera ssp. sylvestris populations, possible to be used as starting plant material for research in general and further breeding of cultivars and grapevine rootstocks.
