Epilepsy surgery has been shown to be an effective treatment for patients with intractable epilepsy. The only randomized controlled trial conducted in this setting to date found a dramatic advantage for surgery over medical treatment in temporal lobe epilepsy. In carefully selected patients, epilepsy surgery can control seizures, improve quality of life and reduce costs of medical care. Advances in diagnostic techniques are likely to improve patient selection, facilitate localization of epileptic foci and functional areas, and enable better prediction of outcomes.

Non-persistence with multiple secondary prevention medications for peripheral arterial disease among older hypertensive patients.
Front Pharmacol
December 2024
School of Pharmacy, University of Eastern Finland, Kuopio, Finland.
Introduction: The benefit of secondary prevention in hypertensive patients with peripheral arterial disease (PAD) is based on continual simultaneous taking of statins, antiplatelet agents and antihypertensive agents, preferably angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs). Our study was aimed at a) the analysis of the extent of non-persistence with multiple medication classes, and b) identifying factors associated with the likelihood of non-persistence.
Methods: In our cohort study, 3,401 hypertensive patients (1,853 females and 1,548 males) aged ≥65 years treated simultaneously with statins, antiplatelet agents and ACEIs/ARBs and in whom PAD was newly diagnosed during 2012 were analysed.
Quantitative evaluation of electrographic response to electroconvulsive therapy in super-refractory status epilepticus.
Front Neurol
December 2024
Department of Neurology, University of California, San Francisco, San Francisco, CA, United States.
Objective: Electroconvulsive therapy (ECT) has been occasionally applied as a treatment for super-refractory status epilepticus (SRSE). However, the effects of ECT on electrographic activity and related clinical outcomes are largely unknown. Here, we use quantitative approaches on electroencephalography (EEG) data to evaluate the neurophysiological influences of ECT and how they may relate to patient survival.

Front Neuroimaging
December 2024
Department of Biostatistics, University of North Carolina at Chapel Hill, Chapel Hill, NC, United States.
Objective: Resting-state functional MRI (rs-fMRI) may localize the seizure onset zone (SOZ) for epilepsy surgery, when compared to intracranial EEG and surgical outcomes, per a prior meta-analysis. Our goals were to further characterize this agreement, by broadening the queried rs-fMRI analysis subtypes, comparative modalities, and same-modality comparisons, hypothesizing SOZ-signal strength may overcome this heterogeneity.
Methods: PubMed, Embase, Scopus, Web of Science, and Google Scholar between April 2010 and April 2020 via PRISMA guidelines for SOZ-to-established-modalities were screened.
Introduction: Hereditary bleeding disorders stem from the absence or insufficient levels of particular clotting proteins, essential for facilitating coagulation in the clotting cascade. Among the most prevalent are hemophilia A (deficiency of Factor VIII), hemophilia B (deficiency of Factor IX), and von Willebrand disease. Management of pharmacoresistant epilepsy is more difficult in a patient with bleeding disorder due to increased risk of bleeding during surgery.

Epilepsia
December 2024
Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, Ohio, USA.
Objective: The most common medically resistant epilepsy (MRE) involves the temporal lobe (TLE), and children designated as temporal plus epilepsy (TLE+) have a five-times increased risk of postoperative surgical failure. This retrospective, blinded, cross-sectional study aimed to correlate visual and computational analyses of magnetoencephalography (MEG) virtual sensor waveforms with surgical outcome and epilepsy classification (TLE and TLE+).
Methods: Patients with MRE who underwent MEG and iEEG monitoring and had at least 1 year of postsurgical follow-up were included in this retrospective analysis.
