Effects of repetitive transcranial magnetic stimulation combined with paroxetine hydrochloride on executive function in depressed adolescents with non-suicidal self-injury / 中国基层医药

Objective:To investigate the effects of repetitive transcranial magnetic stimulation combined with paroxetine hydrochloride on executive function in depressed adolescents with non-suicidal self-injury.Methods:The clinical data of 120 depressed adolescents with depressive disorders who were admitted to The Second Hospital of Jinhua from August 2021 to July 2022 were retrospectively analyzed. They were randomly assigned to undergo treatment either with paroxetine hydrochloride (control group, n = 60) or repetitive transcranial magnetic stimulation combined with paroxetine hydrochloride (observation group, n = 60). All patients were treated for 2 months. Hamilton Depression Rating Scale-24 (HAMD-24) score, Non-suicidal Self-injury Behavior and Function Scale for Adolescents (ANSSIQ) score, executive function, brain-derived neurotrophic factor, 5-hydroxytryptamine, and clinical efficacy were determined in each group. Results:After treatment, the Hamilton Depression Rating Scale-24 score in the observation group was significantly lower than that in the control group [(15.85 ± 1.08) points) vs. (18.72±1.21) points, t = 13.71, P < 0.001). After treatment, the number of self-injury attacks, number of self-injury impulsions, and the intensity of self-injury thought within 2 weeks in the observation group were significantly lower than those in the control group ( t = 3.42, 3.03, 1.92, all P < 0.05). The scores of the Trail Making Test, Stroop Word test, Stroop Color test, and Stroop Color-Word Interference Test were significantly higher in the observation group than those in the control group ( t = 2.66, 3.33, 3.97, 4.64, all P < 0.01). Brain-derived neurotrophic factor and 5-hydroxytryptamine levels in the observation group were (11.45 ± 1.79) μg/L and (136.68 ± 11.90) μg/L, respectively, which were significantly higher than (9.06±2.21) μg/L and (124.82 ± 10.34) μg/L in the control group ( t = 6.51, 5.83, both P < 0.001). The total response rate in the observation group was significantly higher than that in the control group (91.7% vs. 78.3%, Z = 2.73, P = 0.006). Conclusion:Repetitive transcranial magnetic stimulation combined with paroxetine hydrochloride is highly effective on depressive disorders in adolescents with non-suicidal self-injury. The combined therapy can reduce symptoms, improve executive function and cognitive function, and optimize serological indicators, and thereby deserves the clinical promotion.

Comparative effectiveness of different hepatocellular carcinoma screening intervals or modalities: a systematic review and meta-analysis / 中华医学杂志(英文版)

BACKGROUND@#Current guidelines recommend hepatocellular carcinoma (HCC) screening in high-risk populations. However, the ideal HCC screening interval and screening modality have not been determined. This study aimed to compare the screening efficacy among different modalities with various intervals.@*METHODS@#PubMed and other nine databases were searched through June 30, 2021. Binary outcomes were pooled using risk ratio (RR) with 95% confidence intervals (CIs). Survival rates were also pooled using RR with 95% CIs because most eligible studies only provided the number of survival patients instead of hazard ratio.@*RESULTS@#In all, 13 studies were included. Two random controlled trials (RCTs) and six cohort studies compared screening intervals for ultrasonography (US) screening and found no significant differences between shorter (3- or 4-month) and longer (6- or 12-month) screening intervals in terms of early HCC proportion, HCC significant mortality, 1-year survival rate; screening at 6-month interval significantly increased the proportion of early HCC (RR = 1.17, 95% confidence interval [CI]: 1.08-1.26) and prolonged the 5-year survival rate (RR = 1.39, 95% CI: 1.07-1.82) relative to the 12-month interval results. Three other RCTs and two cohort studies compared different screening modalities in cirrhosis or chronic hepatitis B, which indicated no statistical differences in the proportion of early HCC (RR = 0.89, 95% CI: 0.40-1.96) and HCC mortality (RR = 0.69, 95% CI: 0.23-2.09) between the biannual US and annual computed tomography (CT screening). Biannual US screening showed a lower proportion of early HCC than biannual magnetic resonance imaging (MRI) (RR = 0.60, 95% CI: 0.37-0.97) and biannual US combined with annual CT (RR = 1.31, 95% CI: 1.13-1.51) screening. The proportion of early HCC in the contrast-enhanced US group was slightly higher than that in the B-mode US (RR = 1.08, 95% CI: 1.00-1.23) group.@*CONCLUSIONS@#The evidence suggests that 6 months may be the best HCC screening interval for US screening. The effectiveness of CT and MRI is better than US during same screening intervals. However, MRI and CT are more expensive than US, and CT also can increase the risk of radiation exposure. The selection of CT or MRI instead of US should be carefully considered.@*REGISTRATION@#No. CRD42020148258 at PROSPERO website ( https://www.crd.york.ac.uk/PROSPERO/ ).

Introduction on 'assessing the risk of bias of individual studies' in systematic review of healthcare intervention programs revised by the Agency for Healthcare Research and Quality / 中华流行病学杂志

This paper summarizes the Risk of Bias of Individual Studies in Systematic Reviews of Health Care Interventions revised by the Agency for Healthcare Research and Quality (AHRQ) and introduces how to use Revman software make risk of bias graph or risk of bias summary.AHRQ tool can be used to evaluate following study designs:RCTs,cohort study,case-control study (including nested case-control),case series study and cross-sectional study.The tool evaluates the risk of bias of individual studies from selection bias,performance bias,attrition bias,detection bias and reporting bias.Each of the bias domains contains different items,and each item is available for the assessment of one or more study designs.It is worth noting that the appropriate items should be selected for evaluation different study designs instead of using all items to directly assess the risk of bias.AHRQ tool can be used to evaluate risk of bias individual studies when systematic reviews of health care interventions is including different study designs.Moreover,the tool items are relatively easy to understand and the assessment process is not complicated.AHRQ recommends the use of high,medium and low risk classification methods to assess the overall risk of bias of individual studies.However,AHRQ gives no recommendations on how to determine the overall bias grade.It is expected that future research will give corresponding recommendations.

Introduction to PRISMA-CI extension statement and checklist systematic reviews on complex interventions / 中华流行病学杂志

Comprehensive interventions have been widely used in health system, public health, education and communities and have become increasingly focus of systematic reviews. There have been many reporting guidelines about systematic reviews, but they do not take the features of comprehensive interventions in medical area into consideration. As a result, PRISMA-CI has been developed as an extension of PRISMA, which adds or modifies the essential items of PRISMA. This paper introduces the items of PRISMA-CI and explains the items with an example to help authors, publishers, and readers understand PRISMA-CI and use it in systematic reviews on comprehensive interventions. As it become more and more popular with comprehensive interventions, PRISMA-CI will provide important structure and guidance for its systematic review and Meta-analysis.

Impact of glucagon-like peptide-1 receptor agonists on nasopharyngitis and upper re-spiratory tract infection among patients with type 2 diabetes:a network meta-analy-sis / 北京大学学报(医学版)

Objective:To systematically review the effects of glucagon-like peptide-1 receptor agonists (GLP-1 RAs)on two common respiratory system adverse events (RSAE:nasopharyngitis and upper re-spiratory tract infection)among type 2 diabetes (T2DM).Methods:Medline,Embase,Clinical trials and Cochrane library were searched from inception through May 201 5 to identify randomized clinical trials (RCTs)assessed safety of GLP-1 RAs versus placebo or other anti-diabetic drugs in T2DM.Network meta-analysis within a Bayesian framework was performed to calculate odds ratios for the incidence of RSAE.Results:In the study,50 RCTs were included,including 1 3 treatments:7 GLP-1 RAs (exenati-de,exenatide-long-release-agent,liraglutide,lixisenatide,taspoglutide,albiglutide and dulaglutide), placebo and 5 traditional anti-diabetic drugs(insulin,metformin,sulfonylureas,sitagliptin and thiazo-lidinediones ketones).Compared with insulin,taspoglutide significantly decreased the incidence of naso-pharyngitis (OR =0.67,95%CI:0.46 -0.96).Significant lowering effects on upper respiratory tract infection were found when taspoglutide versus placebo (OR =0.57,95%CI:0.34 -0.99)and insulin (OR =0.39,95%CI:0.23 -0.73).The result from the network meta-analysis based on Bayesian theo-ry could be used to rank all the treatments included,which showed that taspoglutide ranked last with mi-nimum risk on nasopharyngitis and upper respiratory tract infection.Conclusion:Taspoglutide was associ-ated with significantly lowering effect on RSAE.
