Physical exercise to rebalance kynurenine metabolism in borderline personality disorder - Preliminary findings.

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
Systemic inflammation and dysregulated kynurenine (KYN) metabolism are increasingly recognised as key factors in various psychiatric disorders. Imbalances in the KYN pathway are associated with psychological and cognitive symptoms across disorders like depression and schizophrenia, yet remain unexplored in borderline personality disorder (BPD). This study is the first to compare KYN metabolism together with the myokine IL-6 in BPD patients and healthy controls and to examine acute exercise effects on this pathway in BPD. Fourteen patients with BPD and nine controls participated in two experimental conditions: cycling exercise and a control session. Serum samples were analysed for tryptophan (TRP), KYN, kynurenic acid (KA), and quinolinic acid (QA). Results revealed greater QA/KYN and lower KA/KYN and KA/QA ratios in BPD, indicating a shift toward the neurotoxic branch. Acute exercise increased KA, KA/KYN, KA/QA, and IL-6 levels, highlighting its potential to enhance neuroprotective KYN activity. These findings suggest KYN pathway dysregulation in BPD and support physical exercise as a promising intervention to rebalance this pathway. Further research should investigate long-term exercise effects and their impact on psychological outcomes in BPD.
