This study aimed to investigate the clinical predictors of post-ictal headache (PIH) in patients with epilepsy in a tertiary center in Brazil. Methods: 302 individuals with adult-onset epilepsy were followed for 9.8 years in our Hospital. Structured questionnaires about headaches were applied. The presence of PIH was the primary outcome. We used multilevel linear modeling in our data analysis. Results: From the total, 46.3% had post-ictal headaches. Tension-type post-ictal headache was present in 55% (N = 77) of the subjects, migrainous in 32.1% (N = 45), and both types in 12.8% (N = 18). Family history of migraine (Odds ratio: 1.696; 95% CI: 1.372 to 2.096), diagnosis of drug-resistant epilepsy (Odds ratio: 1.169; 95% CI: 1.135 to 2.146), months since last visit (Odds ratio: 1.464; 95% CI: 1.243 to 2.888), and generalized seizure onset type of epilepsy (Odds ratio: 1.527; 95% CI: 1.114 to 1.668), were significant determinants of PIH on multilevel linear modeling. Discussion: PIH are associated with drug-resistant epilepsy, generalized seizures, and family history of migraine. The rates of pos-ictal headaches could be influenced by the use of antiepileptic drugs.

The aim of this study was to investigate the cardiovascular risk profile of the participants recruited from stroke awareness campaigns in Santa Maria RS, Brazil, from 2012 to 2016, using the simplified version of the Framingham Risk Score (FRS). Questionnaires were used to evaluate 1,061 participants from 20 to 74 years old. Data on cardiovascular risk factors were obtained. The prevalence of risk factors and mean FRS for men and women were estimated. The FRS for women was 11.8% (moderate risk) and 24.7% for men (high risk). The vascular age for women was 61.6 years, whereas the vascular age for men was 66 years. Two percent of women had hypertension and diabetes, while both these risk factors were present in 5% of men. Based on the data, the prevalence of stroke risk factors is worrisome, as are the numbers of individuals with moderate and high cardiovascular risk in Santa Maria.

Thioacetamide (TAA) is a hepatotoxin that rapidly triggers the necrotic process and oxidative stress in the liver. Nevertheless, organic selenium compounds, such as β-selenoamines, can be used as pharmacological agents to diminish the oxidative damage. Thus, the aim of this study was to investigate the protective effect of the antioxidant β-selenoamines on TAA-induced oxidative stress in mice. Here, we observed that a single intraperitoneal injection of TAA (200 mg/kg) dramatically elevated some parameters of oxidative stress, such as lipid peroxidation and reactive oxygen species (ROS) production, as well as depleted cellular antioxidant defenses. In addition, TAA-induced edema and morphological changes in the liver, which correlate with high serum aspartate and alanine aminotransferase enzyme activities, and a decrease in cell viability. Conversely, a significant reduction in liver lipid peroxidation, ROS production, and edema was observed in animals that received an intraperitoneal injection of β-selenoamines (15.6 mg/kg) 1 h after TAA administration.
