SmartTots – Perspectives from the Front Lines
Millions of children undergo surgery annually. Recent studies suggest there may be reason for concern. This video, featuring Dr. Dean Andropoulos, Dr. Peter Davis, and Dr. Caleb Ing, provides a summary as to why research is needed and the type that is needed.

Ethanol (EtOH) exposure during a period comparable to the third trimester in human results in obvious neurotoxicity in the developing hippocampus and persistent deficits in hippocampal neurogenesis. Dexmedetomidine (DEX), a highly selective α-2-adrenergic agonist has been demonstrated to restore the impaired neurogenesis and neuronal plasticity in the dentate gyrus (DG) that follows neurological insult. However, the protective roles of DEX in the EtOH-induced deficits of postnatal neurogenesis in the hippocampus are still unknown.
miR-455-3p alleviates propofol-induced neurotoxicity by reducing EphA4 expression in developing neurons
Propofol, an aesthetic agent in paediatric patients, results in neurotoxicity in the developing neurons. To reduce side effects of propofol, the protective role of miR-455-3p (microRNA-455-3p) in developing rat brain was investigated.
Propofol inhibits the expression of Abelson nonreceptor tyrosine kinase without affecting learning or memory function in neonatal rats
Propofol is one of the most commonly used intravenous drugs to induce and maintain general anesthesia. In vivo and in vitro studies have shown that propofol can affect neuronal growth, leading to apoptosis and impairing cognitive function. The Abelson nonreceptor tyrosine kinase (c-Abl) is associated with both neuritic plaques and neurofibrillary tangles in the brains of patients with Alzheimer’s disease and other neurodegenerative diseases. This study aimed to explore the effect of propofol on apoptosis and neurocognition through its regulation of c-Abl expression in vivo and in vitro.
MicroRNA-204-5p mediates sevoflurane-induced cytotoxicity in HT22 cells by targeting brain-derived neurotrophic factor
Sevoflurane is widely used as an inhalational anesthetic in clinical practice. However, sevoflurane can cause cytotoxicity and induce learning capacity decline in patients. A previous publication indicated that miR-204-5p might have a close relationship with sevoflurane-induced neurotoxicity. When exposed to sevoflurane, the expression of miR-204-5p in neonatal hippocampus of rats was significantly increased. Hence, we aimed to investigate the role of miR-204-5p in sevoflurane-induced neurotoxicity using a mouse hippocampal neuronal cell line (HT22).
The protective effect of trilobatin against isoflurane-induced neurotoxicity in mouse hippocampal neuronal HT22 cells involves the Nrf2/ARE pathway
Long-term exposure to isoflurane may induce long-term developmental neurotoxicity and cognitive impairments in the neonatal brains. Trilobatin, a leaf extract from the Chinese traditional sweet tea Lithocarpus polystachyus Rehd, possesses various biological properties including anti-inflammatory and anti-oxidant properties. Our study aimed to explore the neuroprotective effect of trilobatin on isoflurane-induced neurotoxicity in mouse hippocampal neuronal HT22 cells.
