Protective effects of folic acid on ischemia‒reperfusion injury in rat uterus: reduces inflammation damage and apoptotic death.

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
backgroundUterine torsion is a pregnancy pathology that poses risks to both maternal and fetal health. This condition is closely associated with the relaxation of uterine ligaments due to hormonal changes and the increased size of the gravid uterus. It occurs when the uterus rotates around its own axis. This torsion can result in ischemia, and if untreated, may progress to necrosis and fetal loss. Folic acid has protective effects against oxidative stress, inflammation, and apoptosis. The aim of this study was to investigate the potential of folic acid to reduce ischemia‒reperfusion (IR) injury in the rat uterus.
resultsIR caused severe edema, inflammation, congestion, hemorrhage, vasoconstriction, and necrosis in the uterus. Histopathological damage was less pronounced in rats treated with folic acid. Although the endometrial layer, critical for fertility, suffered significant damage, folic acid effectively prevented this injury. Immunohistochemical analysis revealed that caspase-3 activity, a marker of apoptosis, increased in response to IR. However, folic acid treatment attenuated this activity, and uterine inflammation also reduced. High-dose folic acid inhibited TNF-alpha immunoreactivity. Interestingly, folic acid did not activate antioxidant mechanisms to reduce oxidative stress. Nevertheless, it mitigated IR-induced damage by reducing endometrial injury and preventing inflammation and apoptosis.
conclusionsAs a result, uterine torsion can lead to endometrial damage, degeneration, inflammation, and apoptosis, potentially affecting fertility. High-dose folic acid treatment may protect the uterus from these damages, thereby preserving fertility. This study suggests that folic acid, particularly at high doses, may be safe and beneficial treatment to prevent IR damage and promote uterine health.
