Article Synopsis
  • - The objective of the study was to review how neonatal status epilepticus (SE) is defined and measured, focusing on literature available on seizure burden in newborns.
  • - The review analyzed 44 studies that primarily included infants with conditions like hypoxic-ischemic encephalopathy, using continuous EEG (cEEG) for SE identification, and mostly defined SE via specific seizure durations.
  • - Key findings revealed significant variability in definitions of neonatal SE, with a consistent trend showing that higher seizure burden was linked to worse outcomes in the 16 studies that explored this relationship.

Article Synopsis
  • Decreased activity of the SLC26A4 protein, critical for ear fluid balance, is linked to hearing loss.
  • Researchers found that the μ2 subunit of the AP-2 complex plays a key role in controlling SLC26A4's presence at the cell membrane where it helps reabsorb endolymph in the inner ear.
  • By blocking clathrin-mediated endocytosis, they showed that more SLC26A4 accumulates on cell surfaces, suggesting that the SLC26A4-μ2 interaction directly influences how much SLC26A4 is available where it’s needed.

This is the first study to quantify the accuracy, sensitivity, and specificity of the human olfactory system in detecting peanuts in common food items. With more competing sensory input, the human olfactory sensitivity to peanuts decreases; this is especially evident when peanuts are mixed in sauces. Metrics established in this study can be used to develop standards for determining the clinical utility of allergen detecting devices that are currently under development.

Article Synopsis
  • Limited guidance on psychogenic non-epileptic seizures (PNES) in children led to the creation of consensus recommendations by the ILAE Task Force, who conducted a scoping review and gathered expert opinions through a Delphi process.
  • The review of 77 studies revealed that the majority were retrospective, with video electroencephalography (vEEG) being the primary identification method, and better outcomes linked to access to psychological support.
  • Key recommendations include taking a thorough developmental history, using vEEG for diagnosis, involving an epilepsy expert post-diagnosis, providing educational materials, and screening for mental health issues in all children with PNES.

Prior to clinical trials, preclinical testing of oncology drug candidates is performed by evaluating drug candidates with in vitro and in vivo platforms. For in vivo testing, animal models are used to evaluate the toxicity and efficacy of drug candidates. However, animal models often display poor translational results as many drugs that pass preclinical testing fail when tested with humans, with oncology drugs exhibiting especially poor acceptance rates.

The discrepancies between the findings in preclinical studies, and in vivo testing and clinical trials have resulted in the gradual decline in drug approval rates over the past decades. Conventional in vitro drug screening platforms employ two-dimensional (2D) cell culture models, which demonstrate inaccurate drug responses by failing to capture the three-dimensional (3D) tissue microenvironment in vivo. Recent advancements in the field of tissue engineering have made possible the creation of 3D cell culture systems that can accurately recapitulate the cell-cell and cell-extracellular matrix interactions, as well as replicate the intricate microarchitectures observed in native tissues.

The human, as a biological system, is an open system embedded within larger systems -including the family, culture, and socio-political environment. In this context, a patient with functional seizures (FS) is embedded in relationships, educational/professional institutions, culture, and society. Both connection to these broader systems and the quality of these connections, as well as the soundness of each system in and of itself, influence the health and well-being of patients in positive or negative ways.
