Carbamazepine-Venlafaxine ER Overdose Caused Drug-Level Rebound and Bowel Ischemia

TL;DR: A 2026 study in Critical Care Explorations described a 45-year-old woman whose extended-release carbamazepine and venlafaxine overdose led to cardiac arrest, delayed serotonin syndrome, rebounding carbamazepine levels, bowel ischemia, and right hemicolectomy after retained gastrointestinal drug material kept releasing medication. Key Findings Extended-release overdose: The patient had altered mental status after a carbamazepine-venlafaxine ER …

MSA Drug Repurposing Review Highlighted Ubiquinol and Exenatide Signals

TL;DR: A 2026 review in Translational Neurodegeneration found that most repurposed multiple system atrophy drugs failed to show disease-slowing effects in trials, while ubiquinol produced the clearest placebo-controlled motor-progression signal. Key Findings No proven disease-modifying therapy: Multiple system atrophy remains a rapidly progressive neurodegenerative disease without an approved treatment that slows progression. Four target classes …

Bacterial Polysaccharides Activated NSM Neurons and Shifted C. elegans Feeding Behavior

TL;DR: A 2026 Current Biology study found that bacterial polysaccharides, including peptidoglycan from Gram-positive bacteria, activated the C. elegans NSM enteric sensory neuron and shifted feeding and movement behavior through acid-sensing ion channels. Key Findings NSM sensed ingested bacteria: the enteric sensory neuron NSM, which projects into the C. elegans pharyngeal lumen, responded when worms …

Brain Iron Deficiency Sensitized a Dopamine-Opioid Restless Legs Pathway

TL;DR: A 2026 mouse study in Neuropsychopharmacology found that brain iron deficiency made an opioid-responsive striatal pathway unusually sensitive to D1 dopamine receptor stimulation, pointing to a possible circuit mechanism for restless legs syndrome and opioid-withdrawal restlessness. Key Findings Iron-deficient mouse model: Researchers used a low-iron diet to create brain iron deficiency (BID), a rodent …

Resting-State EEG Network Markers Distinguished Epilepsy From Functional Seizures

by
Resting-State EEG Network Markers Distinguished Epilepsy From Functional Seizures

TL;DR: A 2026 medRxiv preprint found that multivariate resting-state electroencephalography (EEG) network markers separated non-lesional epilepsy from functional/dissociative seizures above chance, but the best model was stronger at identifying epilepsy than at identifying functional/dissociative seizures. Key Findings 148 suspected seizure cases: Researchers analyzed medication-free, visually normal, eyes-closed EEG recordings from 75 people later diagnosed with …

Occult Sleep Apnea Was Common in Hodgkin Lymphoma Survivors After Mantle Radiation

TL;DR: A 2026 study in Journal of Clinical Sleep Medicine found that 36 of 42 Hodgkin lymphoma survivors tested after mantle radiation therapy had obstructive sleep apnea (OSA), despite mostly normal BMIs and slender necks — an under-recognized phenotype linked to dropped head syndrome. Key Findings 182 long-term HL survivors: All had received mantle radiation …
