Metabolic regulation of amino acids provides an important basis for individualized nutritional therapy for patients with gastric cancer during the perioperative period.

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
backgroundGastric cancer is a prevalent malignancy worldwide, with early detection and treatment being vital to improving patient outcomes. Amino acids (AAs), as essential regulators in cancer cell metabolism, are implicated in the progression and response to treatment.
methodsThis study aimed to investigate the dynamics of plasma AA levels in gastric cancer patients preoperatively, postoperatively, and following nutritional intervention, comparing them to healthy controls. We analyzed 22 AAs in plasma samples from 66 gastric cancer patients and 55 healthy individuals.
resultsThe results show that significant preoperative elevation of AAs, such as threonine (Thr), serine (Ser), proline (Pro), lysine (Lys), arginine (Arg), citrulline (Cit), glutamine (Gln), glycine(Gly), and alanine (Ala), with reductions in taurine (Tau), phenylalanine (Phe) and hydroxylysine (Hylys). Post-surgery, levels of many AAs decreased markedly, but were partially restored following nutritional intervention, with some exceeding preoperative values. Nevertheless, specific AAs, including methionine (Met) and Gln, remained lower than in healthy controls, suggesting potential benefit from targeted supplementation. Correlations between AA changes and postoperative recovery indicators were observed; notably, increased postoperative Thr, Ser, Tau, tyrosine (Tyr), glutamic acid (Glu), and Hylys levels were associated with quicker gastrointestinal recovery. Additionally, several AAs, such as Pro, Lys, Tyr, Met, Cit, and Glu, were linked to reduced inflammation, as reflected by C-reactive protein (CRP) and white blood cell (WBC) levels, suggesting roles in the postoperative immune response. Pathway enrichment analysis highlighted metabolic pathways involving Gly, Ser, Phe, Tyr, Lys, and Met as critical in the recovery process.
conclusionsThese findings underscore the potential of AA profiles as biomarkers for postoperative recovery and suggest nutritional interventions targeting specific AAs may improve outcomes.
