Role of Hippocampal Glutamatergic Synaptic Alterations in Sevoflurane-Induced Cognitive Dysfunction in Aged Mice.
Article in CNS neuroscience & therapeutics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsPerioperative neurocognitive disorders (PND), including postoperative delirium (POD) and postoperative cognitive dysfunction (POCD), are common following anesthesia and surgery in older patients and significantly increase morbidity and mortality. However, the underlying mechanism of PND is unclear. Our study aims to analyze the differentially expressed genes (DEGs) in excitatory neurons and investigate the role of hippocampal glutamatergic synaptic alterations in sevoflurane-induced cognitive dysfunction in aged mice.
methodsWe performed single-nucleus RNA sequencing (snRNA-seq) technology to examine the alterations of excitatory neurons in hippocampus induced by sevoflurane in aged mice. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of DEGs were performed in excitatory neurons. At last, immunofluorescence staining was used to validate sevoflurane-induced alternation of glutamatergic synapses in the hippocampus of aged mice.
resultsThis study demonstrates that DEGs in excitatory neurons are associated with reduction of glutamatergic synapses and cognitive dysfunction. After immunofluorescence staining validation, we also confirmed that sevoflurane anesthesia decreased the density of glutamatergic synapses in the hippocampus of aged mice.
conclusionsOur findings demonstrated a key role of hippocampal glutamatergic synaptic alterations in sevoflurane-induced cognitive dysfunction in aged mice.
