BACKGROUND Stroke is a leading cause of disability and death in advanced heart failure patients supported with a continuous-flow left ventricular assist system (CF-LVAS). Statins (HMG-CoA reductase inhibitors) reduce the risk of major cardiovascular and neurological events such as stroke, but their impact has not been evaluated in patients implanted with a CF-LVAS. We sought to explore the association between use of statin therapy and subsequent occurrence of neurological events, particularly stroke, following CF-LVAS implantation. METHODS We performed a single center, retrospective, observational cohort study in 200 consecutive adults implanted with a durable CF-LVAS over a 10-year period (2008-2018). We compared patients according to statin use following pump implantation, stratified by an exploratory analysis of pump type (HeartMate II, HeartWare HVAD, and HeartMate 3 [HM3] LVAS). RESULTS Overall, 24% of CF-LVAS recipients developed at least 1 neurological event, at a rate of 0.11 events per patient-year ( continue using statins following CF-LVAS in an effort to decrease the incidence of ischemic stroke. Severe acute respiratory syndrome coronavirus-2 is still active in Wuhan, China, and is spreading to the rest of the world. Recently, perioperative anesthetic management in patients with suspected or confirmed coronavirus-2 has been reported. However, little has been reported on the anesthetic management of patients undergoing aortic dissection repair in patients with suspected severe acute respiratory syndrome coronavirus-2 infection. During the outbreak in Wuhan, the authors' team completed 4 cases of aortic dissection repair successfully in patients with suspected severe acute respiratory syndrome coronavirus-2 infection. The purpose of the present report is to summarize current knowledge and experiences on anesthetic management in this patient population and to provide clinical practice guidelines on anesthetic management and infection prevention and control in these critically ill patients. Isolated pontine infarcts are common and are often associated with well-described syndromes that are classified based on their specific clinical presentation and arterial stroke territories. Here we present a case of acute combined diplopia and unilateral lower extremity sensory abnormality. Diffusion-weighted magnetic resonance imaging revealed a punctate area of acute ischemia in the right medial pontine mid-tegmentum. These findings suggest a unique pontine stroke syndrome characterized by acute ischemic injury at the intersection of the medial lemniscus and cranial nerve VI. Published by Elsevier Inc.We administered intravenous thrombolytic therapy to a 51-year-old female patient with a 101-min stroke onset. The patient was unconscious during the manifestation of symptoms. Computed tomography angiography examination of the intracranial artery at the time of admission suggested that the left middle cerebral artery was occluded. The patient regained consciousness after the intravenous thrombolytic treatment was administered. On an urgent cerebral angiography, it was revealed that the recanalization of the left middle cerebral artery was successful. Although blood perfusion was restored, occlusion of the distal blood flow remained. The symptoms of the patient gradually improved after the treatment. However, 6 months after the onset of the condition, intracranial aneurysms formed distal to the recanalized arteries that were previously embolized. The full process underlying the development of cerebral embolism caused by atrial myxomas and subsequent formation of aneurysms is illustrated in this patient. Although the underlying mechanism remains unclear, intravenous thrombolysis can successfully restore cerebral blood flow in and may improve the prognosis of patients with cerebral embolism caused by cardiac myxoma. Despite the positive revascularization therapy, the occurrence of the complication of intracranial aneurysms is possible. Long-term follow-up to evaluate the progression of myxomatous aneurysms after cerebral embolism with conservative treatment may be a suitable strategy for managing such patients. OBJECTIVE To evaluate the development and management of cerebrovascular risk factors following a pregnancy with preeclampsia. METHODS This is a retrospective chart review including women diagnosed with preeclampsia between 2012 and 2013 with later encounters within 2014-2016. For each subject that met inclusion criteria, the development of cerebrovascular risk factors was determined using ICD codes within the 2014-2016 electronic medical record (EMR). For subjects who developed risk factors, current treatment was determined from the EMR. Demographic data was also documented. Differences in the development and treatment of risk factors were compared among racial groups and age. Descriptive statistics were calculated using SAS statistical software. RESULTS Compared to prepregnancy health status, the incidence of hypertension increased by 1.7 times (P less then .05), hyperlipidemia increased by 4.5 (P less then .05), migraines increased by 2.2 (P less then .05), and diabetes mellitus increased by 2 (P less then .05) after a pregnancy with preeclampsia. Black non-Hispanics had highest rates of hypertension, obesity, and migraines (20.5%, 9.1%, and 6.8%, respectively.) Of hypertensives, 73.6% (42/57) were prescribed medication. Of diabetics, 88.9% (16/18) were prescribed medication. No patients with hyperlipidemia were prescribed a statin. Black non-Hispanics had higher rates of risk factor management (74.3% of hypertensives and 100% of diabetics treated) than white Hispanics (55% and 77.8%, respectively). CONCLUSIONS This study shows a significant increased risk of the development of cerebrovascular risk factors such as hypertension, hyperlipidemia, migraines, and diabetes following a diagnosis of preeclampsia. Opportunities exist for the early treatment of these risk factors, which could reduce the long-term rate of stroke in these women. Short linear antimicrobial peptides are attractive templates for developing new antibiotics. Here, it is described a study of the interaction between two short Trp-rich peptides, horine and verine-L, and model membranes. Isothermal titration calorimetry studies showed that the affinity of these peptides towards large unilamellar vesicles (LUV) having a lipid composition mimicking the lipid composition of S. aureus membranes is ca. selleck compound 30-fold higher than that towards E. coli mimetics. The former interaction is driven by enthalpy and entropy, while the latter case is driven by entropy, suggesting differences in the forces that play a role in the binding to the two types of model membranes. Upon membrane binding the peptides acquired different conformations according to circular dichroism (CD) studies; however, in both cases CD studies indicated stacked W-residues. Peptide-induced membrane permeabilization, lipid flip-flop, molecular packing at the membrane-water interface, and lateral lipid segregation were observed in all cases.
