Lactobacillus ameliorates myocardial ischemia reperfusion injury by attenuating apoptosis, inflammation, oxidative stress, and ferroptosis.

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
backgroundMyocardial ischemia/reperfusion (I/R) injury is a significant complication following acute myocardial infarction (AMI) and lacks effective therapies. The involvement of gut microbiota in regulating ferroptosis during myocardial I/R injury has not been thoroughly explored. This study aimed to investigate the effect of Lactobacillus on myocardial I/R injury and explore its potential mechanisms.
methodsOne hundred fifty eight patients with ST-elevation myocardial infarction (STEMI) were enrolled in our prospective observational study. The correlations between Lactobacillus levels and myocardial injury markers, inflammatory factors, oxidative stress, and ferroptosis were evaluated. Furthermore, 30 rats were treated with Lactobacillus or vehicle control for 4 weeks, followed by myocardial I/R surgery. The protective effects of Lactobacillus against I/R injury were assessed by quantifying myocardial apoptosis, inflammation, oxidative stress, and ferroptosis. In addition, the above results were verified in vitro. The signaling pathways were investigated through the knockdown and overexpression of sirtuin 1 (Sirt1) and nuclear factor erythroid 2-related factor 2 (Nrf2).
resultsIn clinical study, Lactobacillus levels were significantly negatively correlated with myocardial injury markers, inflammatory factors, and malondialdehyde (MDA), but positively correlated with glutathione (GSH). In rats, Lactobacillus decreased the levels of myocardial injury markers, reduced the size of the myocardial infarction area, ameliorated the disordered myocardial cell arrangement, and improved cardiac function. In both in vivo and in vitro studies, Lactobacillus inhibited cardiomyocyte apoptosis by upregulated B-cell lymphoma-2 (Bcl-2), downregulated Bcl-2 associated X (Bax), and caspase-3. Furthermore, Lactobacillus decreased inflammatory factors, MDA, reactive oxygen species (ROS) levels, and increased superoxide dismutase (SOD) activity. For ferroptosis, Lactobacillus upregulated the expression of glutathione peroxidase 4 (GPX4) and downregulated the expressions of acyl-CoA synthetase long-chain family member 4 (ACSL4) and transferrin receptor protein 1 (TfR1). Finally, knockdown and overexpression of Sirt1 and Nrf2 in vitro demonstrated that Lactobacillus exerted the effect by upregulating the Sirt1/Nrf2/HO-1 pathway.
conclusionsOur findings reveals that Lactobacillus protects against myocardial I/R injury by inhibiting apoptosis, inflammation, oxidative stress, and ferroptosis through the Sirt1/Nrf2/HO-1 signaling axis, suggesting a novel probiotic-based therapeutic potential for I/R injury.
