Pediatric massage therapy for treatment of tic disorders in children: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Tic disorder is a common neurodevelopmental disorder in childhood, characterized primarily by motor or vocal tics. However, there is no systematic evaluation of pediatric massage therapy for children with Tic disorder. This study aims to evaluate the effectiveness and safety of massage therapy for children with tic disorder through a comprehensive meta-analysis and systematic review. METHODS: We systematically searched relevant randomized controlled trials from various databases such as CBM, CNKI, VIP, Wanfang database, PubMed, Embase, Web of Science, Cochrane Library, and SINOMED, published up to October 2023. To collect randomized controlled trials on pediatric massage therapy or in combination with other therapies for the treatment of tic disorders in children. The risk of bias in the included articles was assessed using the Cochrane guideline. Meta-analyses were performed using Review Manager 5.4, and publication bias was evaluated by using Begg test and Egger test in Stata SE software. RESULTS: This meta-analysis included 19 randomized controlled trials with 1423 patients. Pediatric massage therapy alone or in combination with conventional medication demonstrated a significant increase in clinical effectiveness rates [risk ratios = 1.15, 95% confidence interval [CI] (1.10, 1.20), Z = 6.54, P < .001], and reduced Yale Global Tie Severity Scale scores [standardized mean difference = -0.85, 95% CI (-1.50, -0.19), Z = 2.54, P = .01] and traditional Chinese medicine syndrome scores [standardized mean difference = -1.35, 95%CI (-2.08, -0.63), Z = 3.66, P = .0002]. In terms of adverse reactions, there was no statistical difference between the experimental and control groups [risk ratios = 0.26, 95% CI (0.14, 0.49), Z = 4.25, P < .001]. The Begg test and Egger test results indicated no publication bias. CONCLUSION: Evidence suggests that pediatric massage therapy is effective in improving tic disorders in children.

Alterations of trace elements (Zn, Se, Cu, Fe) and related metalloenzymes in rabbit blood after severe trauma.

To investigate the status of the trace elements (TEs) and related metalloenzymes activities in the injury and repair process after severe trauma, we established a rabbit model of severe trauma whose Injury Severity Score (ISS) was 22. Concentrations of blood selenium (Se) and serum copper (Cu), zinc (Zn), iron (Fe), and ferritin were measured on D0 (before injury), and day (D) 1, D2, D3, D6, D9, D14, D21, D28 after trauma, respectively. The activities of glutathione peroxidase (GPx), Cu/Zn superoxide dismutase (Cu/Zn-SOD), myeloperoxidase (MPO), the contents of lipid peroxidation product malondialdehyde (MDA) and serum biochemical profile were detected synchronously. In addition, the morphologic changes of major organs were observed at different time intervals. Results showed that blood Se and serum Zn, Fe contents decreased significantly within 2 weeks after injury. Serum Cu concentration was significantly reduced on D1 but normalized quickly. Serum ferritin level increased during the first week while following an obvious decrease thereafter. The blood GPx activity dropped markedly from D1 to D6, the serum Cu/Zn-SOD activity decreased on D1 and then increased significantly within 2 weeks, and the blood MPO-positive stained cells increased within a week after trauma and followed by a decrease from D14 to D21. The serum MDA increased significantly on D6. Seven of 34 rabbits died in 4-6 days after injury. Biochemistry values and pathological features revealed these rabbits died of multiple organ dysfunction syndrome (MODS). Our experiment suggested that the circulating TEs status is dramatically modified in response to trauma, which might be a factor in MODS.
