Objective: Cerebral amyloid angiopathy (CAA) is a major cause of spontaneous intracranial hemorrhage in older adults. Epilepsy represents a possible sequela of the disease. To date, studies on epilepsy in CAA are lacking, and the few data available mainly focus on CAA-related inflammation (CAA-ri), the inflammatory form of the disease. Methods:In this retrospective observational study, we consecutively recruited CAA patients observed over a time span of 10 years, collecting demographic, clinical, and instrumental data. Significant baseline characteristics were evaluated as potential risk factors for the development of epilepsy in the CAA population, and in the subgroups of CAA-ri and CAA without inflammatory reaction (CAA-nri).The effect of potential risk factors for epilepsy was measured as odds ratio with 95% confidence interval.Results: Within 96 recruited CAA cases, 33 (34.4%) developed epilepsy during follow-up (median = 13.5 months). The prevalent type of seizure was focal (81.3%); 12.1% of the epileptic patients presented status epilepticus, and 6.1% developed drug-resistant epilepsy. Electroencephalographic traces revealed slow and epileptic discharge activity in the majority of epileptic patients, but also in those without epilepsy. The presence of focal or disseminated cortical superficial siderosis (cSS) was associated with an increased risk of epilepsy in the CAA-nri group, and the association with CAA-ri and epilepsy was present in the overall population.Significance: Epilepsy is a common manifestation during the course of CAA, where CAA-ri and cSS represent predisposing factors for the development of seizures. These data suggest the importance of a deep characterization of CAA patients, to better select those more prone to develop epilepsy.

Coronary artery disease (CAD) is the leading cause of mortality globally. Although substantial advances have been made in the diagnosis, management, and risk stratification of CAD, there is still a need for novel diagnostic biomarkers and new therapeutic targets to prevent the epidemic of the disease. Recently, growing evidence has linked dysregulated microRNA (miRNAs) to cardiovascular diseases, including CAD. miRNAs are endogenous, stable, single-stranded, short, non-coding RNAs, and may have utility as diagnostic and prognostic biomarkers for CAD. Dysregulated miRNAs are involved in regulating lipid and glucose homeostasis pathways, renin-angiotensin-aldosterone pathways, inflammation, endothelial and vascular smooth cell phenotypes promoting atherosclerotic plaque development, progression, and instability. Additionally, miRNAs are stable and easily accessible in the extracellular space, may reside in microvesicles, and are detectable in serum or plasma, making them attractive biomarkers for the diagnosis and prognosis of cardiovascular disease. Accumulating studies suggest that miRNAs could be useful biomarkers for early discrimination of patients presenting with myocarditis or Takotsubo syndrome from those with a diagnosis of acute myocardial infarction, early prognostication of patients presenting with acute coronary syndromes, and accurate detection of left ventricular remodeling after a chronic or acute ischemic event. Moreover, miRNAs represent potential novel therapeutic targets for CAD or other cardiovascular diseases. This review provides an overview of the effects of the entire spectrum of CAD, its major risk factors, and complications on levels of circulating miRNAs, as well as the limitations and challenges of their potential clinical applications.

Introduction: Fenfluramine(FFA) is an amphetamine derivative that promotes the release and blocks the neuronal reuptake of serotonin. Initially introduced as an appetite suppressant, FFA also showed antiseizure properties. This systematic review aimed to assess the efficacy and safety of FFA for the treatment of seizures in patients with epilepsy. Methods: We systematically searched (in week 3 of June 2022) MEDLINE, the Cochrane Central Register of Controlled Trials, and the US National Institutes of Health Clinical Trials Registry. Randomized, double-or single-blinded, placebo-controlled studies of FFA in patients with epilepsy and uncontrolled seizures were identified. Efficacy outcomes included the proportions of patients with C 50% and 100% reductions in baseline seizure frequency during the treatment period. Tolerability outcomes

Cardiovascular diseases and cancer are the leading cause of morbidity and mortality globally. Cardiotoxicity from chemotherapeutic agents results in substantial morbidity and mortality in cancer survivors and patients with active cancer. Cardiotoxicity induced by 5-fluorouracil (5-FU) has been well established, yet its incidence, mechanisms, and manifestation remain poorly defined. Ischemia secondary to coronary artery vasospasm is thought to be the most frequent cardiotoxic effect of 5-FU. The available evidence of 5-FU-induced epicardial coronary artery spasm and coronary microvascular dysfunction suggests that endothelial dysfunction or primary vascular smooth muscle dysfunction (an endothelial-independent mechanism) are the possible contributing factors to this form of cardiotoxicity. In patients with 5-FU-related coronary artery vasospasm, termination of chemotherapy and administration of nitrates or calcium channel blockers may improve ischemic symptoms. However, there are variable results after administration of nitrates or calcium channel blockers in patients treated with 5-FU presumed to have myocardial ischemia, suggesting mechanisms other than impaired vasodilatory response. Clinicians should investigate whether chest pain and ECG changes can reasonably be attributed to 5-FU-induced cardiotoxicity. More prospective data and clinical randomized trials are required to understand and mitigate potentially adverse outcomes from 5-FU-induced cardiotoxicity.
