Objective: To evaluate the efficacy of levetiracetam (LEV) in continuous spikes and waves during slow sleep (CSWS). Despite first description dates back to 1971, no agreement exists about CSWS treatment. The condition is rare and controlled clinical trials are very difficult to perform, so the reports about efficacy of different drugs are anecdotal.
Patients And Methods: We introduced LEV in three children affected by symptomatic focal epilepsy and pharmacoresistant CSWS and evaluated clinical, neuropsychological and electroencephalographic outcome.
Results: Two cases responded completely, one case showed only a mild reduction of spikes and waves during slow sleep.
Conclusion: Even if our report is anecdotal, LEV expands the spectrum of antiepileptic drugs that can be used for the treatment of CSWS. LEV efficacy should be confirmed in larger series.

Synchronization in spiking neural networks with short and long connections and time delays.

Article Synopsis
- Synchronization in brain networks is crucial for processing information, but time delays in signal transmission can significantly influence this process, especially in more complex spiking neural networks.
- The study involves investigating synchronization conditions and dynamics in a two-dimensional network of adaptive exponential integrate-and-fire neurons, focusing on how delay impacts this behavior.
- Findings reveal that synchronization patterns depend on a combination of properties at different levels, including individual neuron characteristics, network connectivity, and long-range connections, which together affect the emergent activity patterns in the brain.
SARS-CoV-2 Evolution: Implications for Diagnosis, Treatment, Vaccine Effectiveness and Development.

The COVID-19 pandemic, driven by the rapid evolution of the SARS-CoV-2 virus, presents ongoing challenges to global public health. SARS-CoV-2 is characterized by rapidly evolving mutations, especially in (but not limited to) the spike protein, complicating predictions about its evolutionary trajectory. These mutations have significantly affected transmissibility, immune evasion, and vaccine efficacy, leading to multiple pandemic waves with over half a billion cases and seven million deaths globally.

Aims: Concerns over population-level immunity have been heightened with each successive wave of COVID-19, prompting questions about whether it is primarily derived from vaccination efforts or from previous natural infections with the virus. We wished to determine the seroprevalence of SARS-CoV-2 antibodies among healthcare workers (HCWs) in Pretoria (Tshwane), South Africa, and to establish whether they were derived from vaccination or natural infection.
Methods: Serum samples were collected from HCWs during the fourth wave of COVID-19 between 1 December 2021 and 13 March 2022.
Objectives: We assessed the transmission of SARS-CoV-2 and vaccine receipt in a representative sample of wet market workers in a highly dense, low-income setting. Wet markets are key in many Asian settings, including Dhaka, Bangladesh, for fresh food, including animal protein.
Methods: During early 2022, we assessed the prevalence of anti-SARS-CoV-2 antibodies in a random sample of poultry and vegetable workers in 15 wet markets, and investigated associations with socio-demographic characteristics and COVID-19 vaccination.
Association of Sleep Spindle Rate With Memory Consolidation in Children With Rolandic Epilepsy.
Neurology
January 2025
Department of Neurology, Massachusetts General Hospital, Boston.
Background And Objectives: Rolandic epilepsy (RE), the most common childhood focal epilepsy syndrome, is characterized by a transient period of sleep-activated epileptiform activity in the centrotemporal regions and variable cognitive deficits. Sleep spindles are prominent thalamocortical brain oscillations during sleep that have been mechanistically linked to sleep-dependent memory consolidation in animal models and healthy controls. Sleep spindles are decreased in RE and related sleep-activated epileptic encephalopathies.
