Risk of venous thromboembolism in children and adolescents with inflammatory bowel disease: A systematic review and meta-analysis.

BACKGROUND: A two- to three-fold increased risk of venous thrombotic events (VTE) has been demonstrated in patients with inflammatory bowel disease (IBD) compared to the general population, but less is known about the risk of VTE in child- and pediatric-onset IBD. In recent years, several studies have reported the rising incidence rate of VTE in juvenile patients with IBD, and the related risk factors have been explored. AIM: To evaluate the risk of VTE in children and adolescents with IBD. METHODS: Articles published up to April 2021 were retrieved from PubMed, Embase, Cochrane Library, Web of Science, SinoMed, CNKI, and WANFANG. Data from observational studies and clinical work were extracted. The outcome was the occurrence of VTE according to the type of IBD. The available odds ratio (OR) and the corresponding 95% confidence interval (CI) were extracted to compare the outcomes. Effect size (P), odds ratio (OR), and 95%CI were used to assess the association between VTE risk and IBD disease. Subgroup analyses stratified by subtypes of VTE and IBD were performed. RESULTS: Twelve studies (7450272 IBD patients) were included in the meta-analysis. Child and adolescent IBD patients showed increased VTE risk (P = 0.02, 95%CI: 0.01-0.03). Subgroup analyses stratified by IBD (ulcerative colitis (UC): P = 0.05, 95%CI: 0.03-0.06; Crohn's disease (CD): P = 0.02, 95%CI: 0.00-0.04) and VTE subtypes (portal vein thrombosis: P = 0.04, 95%CI: 0.02-0.06; deep vein thrombosis: P = 0.03, 95%CI: 0.01-0.05; central venous catheter-related thrombosis: P = 0.23, 95%CI: 0.00-0.46; thromboembolic events: P = 0.02, 95%CI: 0.01-0.03) revealed a significant correlation between VTE risk and IBD. Patients with IBD were more susceptible to VTE risk than those without IBD (OR = 2.99, 95%CI: 1.45-6.18). The funnel plot was asymmetric, suggesting the presence of significant publication bias. Pediatric and adolescent IBD patients have an increased VTE risk. UC and CD patients exhibited a high risk of VTE. The risk of VTE subtypes was increased in IBD patients. CONCLUSION: The current meta-analysis showed that the incidence and risk of VTE are significantly increased in pediatric and adolescent IBD patients. Thus, IBD might be a risk factor for VTE in children and young adults. High-quality prospective cohort studies are necessary to confirm these findings.

Acupressure for insomnia: A protocol for systematic review and meta-analysis.

BACKGROUND: Insomnia is a public sleep disorder defined as a deficiency of sleep quantity or quality. Acupressure is a low-cost treatment that has potential as an insomnia therapy. METHODS: Four databases will be searched from inception to date. The researchers will screen clinical randomized trials of acupressure and auricular acupuncture for insomnia. The screening of the study, data extraction will be carried out independently by 2 researchers. The specific process will refer to the Cochrane Handbook for Systematic Review. RESULTS: The results of the study will be published in a scientific journal after peer-review. We integrate the latest study about acupressure for insomnia. CONCLUSION: This systematic review will provide evidence for assessing the improvement of acupressure for insomnia. ETHICS AND DISSEMINATION: The systematic review will be published in a peer-reviewed journal. The review will also be disseminated electronically and in print.PROSPERO registration: CRD42018104155.
