Procalcitonin contributes to hippocampal neuronal damage and impairment of LTP: implications for cognitive dysfunction in LPS-induced neuroinflammation rat model.

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
Bacterial meningitis (BM) can lead to cognitive impairment, seriously affecting patients' quality of life. Our previous study demonstrated a significant increase in procalcitonin (PCT) levels in cerebrospinal fluid (CSF) in BM patients, but the functional implications remain unknown. We found high expression of PCT in the hippocampus of LPS-induced neuroinflammation models. PCT had a neurotoxic effect on the primarily cultured hippocampal neurons. The high dose of PCT induced neuronal apoptosis. The low dose of PCT impaired the arborization of hippocampal neurons and reduced the expression of the growth-associated protein-43 (GAP-43) and synaptophysin (SYN). Furthermore, long-term potentiation (LTP) in hippocampal brain slices was decreased after PCT perfusion ex vivo. Our results indicated that PCT had neurotoxic effects on neuronal survival and synaptic plasticity, potentially leading to cognitive impairment after BM.
