RESUMO
Antipsychotics are associated with severe metabolic side effects including insulin resistance; however, the mechanisms underlying this side effect are not fully understood. The skeletal muscle plays a critical role in insulin-stimulated glucose uptake, and changes in skeletal muscle DNA methylation by antipsychotics may play a role in the development of insulin resistance. A double-blind, placebo-controlled trial of olanzapine was performed in healthy volunteers. Twelve healthy volunteers were randomized to receive 10 mg/day of olanzapine for 7 days. Participants underwent skeletal muscle biopsies to analyze DNA methylation changes using a candidate gene approach for the insulin signaling pathway. Ninety-seven methylation sites were statistically significant (false discovery rate < 0.05 and beta difference between the groups of ≥10%). Fifty-five sites had increased methylation in the skeletal muscle of olanzapine-treated participants while 42 were decreased. The largest methylation change occurred at a site in the Peroxisome Proliferator-Activated Receptor Gamma Coactivator 1-Alpha (PPARGC1A) gene, which had 52% lower methylation in the olanzapine group. Antipsychotic treatment in healthy volunteers causes significant changes in skeletal muscle DNA methylation in the insulin signaling pathway. Future work will need to expand on these findings with expression analyses.
RESUMO
OBJECTIVES: Seizures can occur as a result of a variety of health issues. Epilepsy is a common neurological disease and it is the most prevalent cause of seizures. Epileptic patients might experience a seizure attack at any moment. The aim of this study is to assess public knowledge, awareness, attitudes, and practices toward seizure attacks among residents of Makkah city. METHODS: A cross-sectional study was conducted utilizing an online questionnaire, which was distributed through various social media platforms. The questionnaire consisted of five parts, taking sociodemographic characteristics into consideration, and evaluating knowledge, awareness, attitudes, and practices among the general population of Makkah city. RESULTS: A total of 401 participants completed the study questionnaire: 280 (69.8%) participants were females and 121 (30.2%) were males. Overall knowledge regarding epilepsy among the study participants was evaluated. A total of 132 (32.9%) participants had a good level of knowledge, while 269 (67.1%) exhibited poor knowledge. In addition, students had significantly better knowledge (44.7%) than individuals who were employed, retired, or unemployed (27.7%), (P=.004). Furthermore, participants who had previously heard about epilepsy were more knowledgeable (34.3%) than those who had not (P =.041). Additionally, participants who attended a course on seizure control (46.7%) had significantly better knowledge than those who did not (31.2%), (P=.037). CONCLUSION: This study revealed that most of our sample of Makkah city residents had poor overall knowledge of epilepsy and seizure attacks. A health education program and awareness campaigns could help improve this lack of knowledge in Makkah city.
