Supplementary Material for: Aortic stiffness is independently associated with intracranial carotid artery calcification in patients with ischemic stroke

Background and aims Intracranial carotid artery calcification (ICAC), as a strong contributor to the occurrence of ischemic stroke, might be present in the medial or intimal arterial layer. Traditional cardiovascular risk factors (CVRFs) are associated with ICAC; however, its association with new markers of vascular function are less understood. The paper aims to evaluate the relationship between carotid-femoral pulse wave velocity (CF-PWV) and ICAC subtypes. Methods We enrolled 65 patients with ischemic stroke. CF-PWV, systolic, diastolic, mean blood pressure, and pulse pressure (SBP, DBP, MBP, PP) were measured within 6±2 days after stroke onset, CT was performed within 24 hours. ICAC on the stroke site was classified by two methods: volume- and score-based. Tertiles of ICAC volume were determined, and low-grade ICAC (T1) was regarded as a reference. According to the score-based method, (dominant) medial and (dominant) intimal ICAC subtypes were determined. Data were analysed with multivariate logistic regression. Results Medial and intimal ICAC subtypes were found in 34 (52%) and 24 (37%) patients, respectively. In 11% of patients no ICAC calcifications were found. CF-PWV was higher in patients with high-grade ICAC (OR=1.56, 95%CI=1.03-2.35, p=0.035). CF-PWV was higher in patients with the medial ICAC subtype (OR=1.60, 95%CI=1.00-2.55, p=0.049) after adjustment for traditional CVRFs. Conclusions Our study demonstrates that among patients with ischemic stroke, aortic stiffness is independently associated with ICAC, and that medial ICAC, compared with intimal ICAC, is accompanied by more advanced aortic stiffness

Blood pressure in acute ischemic stroke: Challenges in trial interpretation and clinical management: Position of the ESH Working Group on Hypertension and the Brain

Altered blood pressure (BP) is a common phenomenon in acute ischemic stroke (AIS), with high BP being the most frequent scenario. The pathophysiology of BP changes in AIS is complex and only partially understood. The available evidence indicates that extremely high BP during AIS is associated with a poor outcome. Importantly, the observed relationship between BP and stroke outcome may or may not be causally related. Higher baseline BPs in focal cerebral ischemia may indicate preexisting hypertension, but may also be an effect of both nonspecific and stroke-related factors. Although antihypertensive therapy effectively reduces BP in AIS, studies on early BP lowering in AIS produce conflicting results in terms of functional outcome and mortality. Systematic reviews on BP management in AIS did not result in clinically applicable conclusions in general. However, the investigation on the effect of BP and its alterations in AIS are hampered by various important methodological issues. This position statement was prepared by a group of experts from the European Society of Hypertension and invited neurologists to discuss the main reasons for the discrepancies in the current evidence on the prognosis and treatment of altered BP in AIS which should be taken into account in future studies.

Heterogeneity of extraparenchymal primitive neuroectodermal tumors within the craniospinal axis.

Four cases of primitive neuroectodermal tumors (PNETs) with unusual localization (three intraspinal extramedullary and one pontocerebellar) are reviewed. Histologically, they were small round blue cell tumors with diverse patterns. Immunohistochemically, all tumors were positive for at least two neuronal markers, two cases were Mic-2 positive and one showed glial differentiation. The paraffin-embedded tumor specimens were examined by interphase FISH using dual-color probes specific for EWS, HER-2 and BCR loci. Molecular cytogenetic study revealed the presence of EWS rearrangement in two cases and the presence of i(17q) in one tumor. Three tumors exhibited 22 disomy and one was 22 polyploid. Extraparenchymal PNETs within craniospinal axis are heterogeneous from the clinical, histological, immunohistochemical and molecular point of view. These PNETs can be of a central or peripheral type. Multidisciplinary approach is of a basic importance in differential diagnosis of such cases

Routine assessment of cognitive function in older patients with hypertension seen by primary care physicians: Why and how-a decision-making support fromthe working group on'hypertension and the brain'of the European Society ofHypertension and fromthe European GeriatricMedicine Society

The guidelines on hypertension recently published by the European Societies of Hypertension and Cardiology, have acknowledged cognitive function (and its decline) as a hypertension-mediated organ damage. In fact, brain damage can be the only hypertension-mediated organ damage in more than 30% of hypertensive patients, evolving undetected for several years if not appropriately screened; as long as undetected it cannot provide either corrective measures, nor adequate risk stratification of the hypertensive patient. The medical community dealing with older hypertensive patients should have a simple and pragmatic approach to early identify and precisely treat these patients. Both hypertension and cognitive decline are undeniably growing pandemics in developed or epidemiologically transitioning societies. Furthermore, there is a clear-cut connection between exposure to the increased blood pressure and development of cognitive decline. Therefore, a group of experts in the field from the European Society of Hypertension and from the European Geriatric Medicine Society gathered together to answer practical clinical questions that often face the physician when dealing with their hypertensive patients in a routine clinical practice. They elaborated a decision-making approach to help standardize such clinical evaluation. © 2021 Lippincott Williams and Wilkins. All rights reserved
