  • Objective: To investigate the association between xeroderma pigmentosum group D (XPD) Asp312Asn polymorphism and esophageal cancer (EC) susceptibility by meta-analysis. Methods: We searched PubMed up to April 9th, 2012, to identify relevant papers, and 8 published case-control studies including 2165 EC patients and 3141 healthy controls were yielded. Odds ratios (ORs) with relevant 95% confidence intervals (CIs) were applied to assess the association between XPD Asp312Asn polymorphism and EC susceptibility with the Comprehensive Meta-Analysis software, version 2.2. Results: Overall, the meta-analysis results suggested the XPD Asp312Asn polymorphism to be significantly associated with EC susceptibility [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.20, 95%CI=1.05-1.36, p=0.01; and Asp/Asn vs. Asp/Asp: OR=1.15, 95%CI =1.01-1.31, p=0.04]. In the subgroup analysis by ethnicity and cancer type, significantly associations were found for Caucasian populations [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.26, 95%CI =1.08-1.47, p<0.001; Asp/Asn vs. Asp/Asp: OR=1.19, 95%CI =1.02-1.40, p=0.03] and esophageal squamous cell carcinoma [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.19, 95%CI=1.01-1.41, p=0.04]. There was no heterogeneity and no publication bias existed. Conclusions: This meta-analysis shows that the XPD Asp312Asn polymorphism may be a risk factor for developing EC, especially for Caucasian populations and esophageal squamous cell carcinoma.

  • Objectives: To evaluate and summarize the efficacy and safety of manual therapy in temporomandibular disorder(TMD). Methods: Ten databases (Pubmed, Cochrane, EMBASE, AMED, CINAHL, CNKI, and four Korean databases) were searched up to March 2017. Pain and range of motion(ROM) of temporomandibular joint were used as the primary outcome measure, and effective rates, dysfunction scale and adverse events were used as secondary outcome measures. The Cochrane risk of bias tool was used to evaluate the methodological quality. Results: 10 randomized controlled trials(RCTs) involving 603 participants were included. There were no significant differences between the two groups in comparison with placebo manual therapy group. In comparison with Wait-list and conventional treatment groups, manual therapy significantly alleviated pain and ROM. Five RCTs(50.0%) reported adverse events and there were no adverse cases by manual therapy. Conclusions: We found evidence that manual therapy may alleviate symptoms of patients with TMD. A positive effect was observed in comparison with conventional treatment and Wait-list, but no conclusion for the comparisons with placebo manual therapy. There is no evidence of worsening symptoms or causing adverse events.

  • Purpose: This study was a systematic review and meta-analysis designed to evaluate the effects of breastfeeding intervention on breastfeeding rates. Methods: Based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA), a systematic search was conducted using eight core electronic databases and other sources including gray literature from January 9 to 19, 2017. Two reviewers independently select the studies and assessed methodological risk of bias of studies using the Cochrane criteria. The topics of breastfeeding interventions were analyzed using descriptive analysis and the effects of intervention were meta-analyzed using the Review Manager 5.2 software. Results: A total of 16 studies were included in the review and 15 were included for meta-analysis. The most frequently used intervention topics were the importance of good latch-on and frequency of feeding and determining adequate intake followed. The pooled total effect of breastfeeding intervention was 1.08 (95% CI 1.03~1.13). In the subgroup analysis, neither pre-nor post-childbirth intervention was effective on the breastfeeding rates at 1, 3, and 6 months, and neither group nor individual interventions had an effect. Only the 1 month breastfeeding rate was found to be affected by the individual intervention with the persistent strategies 1.21 (95% CI 1.04~1.40). Conclusion: Effective breastfeeding interventions are needed to help the mother to start breastfeeding after childbirth and continue for at least six months. It should be programmed such that individuals can acquire information and specific breastfeeding skills. After returning home, there should be continuous support strategies for breastfeeding as well as managing various difficulties related to childcare.

  • Purpose : This systematic review was conducted to identify which dyadic intervention could be implemented for heart failure patient-family caregiver dyads to improve patient and/or their family caregivers outcomes. Method : Eleven databases were searched from their inception to July, 2021. This review considered any randomized controlled trials that evaluated the effectiveness of intervention including heart failure patient-family caregiver dyads. Two reviewers independently evaluated the methodological quality using the Cochrane Collaboration's tool for assessing risk of bias and extracted details of the included studies. The studies included in this review were not suitable for meta-analysis and therefore the results were presented as a narrative summary. Results : Six studies including 900 dyads were included and mainly primary family caregiver of patients was spouse. Majority of dyadic intervention were focused on psychoeducational intervention excepting one study on mobile health intervention. All studies included in this review focused on patients' outcomes compared to family caregivers' outcomes and dyadic outcomes. Individual interventions improved quality of life among heart failure patients and their family caregivers in two articles. The overall quality of selected articles was low. Conclusions : This study provides moderate support for the use of a dyadic intervention to improve quality of life among heart failure patients and their family caregivers. More rigorous high-quality studies investigating interventions to meet the needs of patient and family caregivers in heart failure care are needed.

  • Objectives: This research aimed to investigate Chinese clinical studies on the treatment of central post-stroke pain (CPSP) and thalamic syndrome after stroke with traditional herbal medicine (THM). Methods: Randomized controlled trials verifying the effects of herbal medicine on treating CPSP and thalamic syndrome after stroke were included in the study. Electrical and hand search were conducted in the China National Knowledge Infrastructure (CNKI), National Discovery for Science Leaders (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (Oasis) for CPSP and thalamic syndrome after stroke. A literature search was performed in the Chinese and Korean databases for papers published from January 1, 2010 to October 1, 2018. The selected literature was assessed by Cochrane's risk of bias. Results: Twelve reports on randomized controlled trials met the inclusion criteria from the 227 identified reports. Effective rate, comparison of visual analogy scale, present pain intensity, pain grading index, recurrence rate, follow-up, and a 36-item short form survey instrument were used to evaluate the treatments. The effective rate of the treatment group was significantly higher than that of the control group in all papers. Side effects occurred less frequently in the treatment group than in the western medicine control group. Conclusions: The treatment of CPSP and thalamic syndrome after stroke with THM was shown to be highly effective. Additional well-designed clinical trials are needed. This study can be used as a basis for further research on the treatment of CPSP and thalamic syndrome after stroke.

  • Objectives : Pityriasis rosea is an acute and subacute papular scaly disease, and is a disease that mainly resolves spontaneously. However, since the outbreak of COVID-19, the possibility that the disease may occur as a sequelae of the disease and side effects of vaccination has been announced. Methods : We searched articles related to oriental treatment of pityriasis rosea at organized in domestic and foreign DBs. Articles were searched for RCT. The results were summarized in tables and graphs, and meta-analysis was performed. Also, we assessed the risk or bias. Results : As a result of setting the herbal medicine alone treatment as an intervention for pityriasis rosea and Western medicine alone as the control group, total 9 articles were searched. We analyzed them and got the results. The efficient rate of the treatment group was statistically significantly higher than that of the control group. In addition, adverse events were significantly less in the treatment group than in the control group. Conclusions : Herbal medicine treatment can be more effective than Western therapy(mainly anti-histamines and glycyrrhizin injection) for pityriasis rosea. In addition, herbal medicine treatment can be superior to Western treatment for safety. However, the limitations of this study include the small number of articles, no other evaluation indicators other than the efficient rate, and insufficient data such as pathological examination.

  • Objectives : This study was designed to investigate the effect of Banhahubak-tang on gastroesophageal reflux disease(GERD) through a systematic review and meta-analysis of randomized controlled trials(RCTs). Methods : RCTs using Banhahubak-tang on GERD was searched in databases such as EMBASE, PubMed, MEDLINE, CENTRAL, CNKI, KISS, RISS, ScienceON, and OASIS. RCTs published up to October 8th, 2021 were included. Meta-analysis was performed by synthesizing outcome data, including Total Effectiveness Rate (TER), Reflux Symptom Index(RSI), Reflux Finding Score(RFS), and Incidence of Adverse Reactions. RevMan 5.4 software was used for data analysis. The Cochrane collaboration bias risk assessment scale was used to evaluate the methodological quality of the included studies. Results : Ten RCTs met the inclusion criteria. The total effective rate was the most commonly used outcome measure. The meta-analysis revealed that the TER in the experimental group was higher than that of the control group(N=2, RR:1.22, 95% CI:1.09 to 1.36, P=0.0004, I2=0%)(N=6, RR:1.22, 95% CI:1.14 to 1.32, P<0.00001, I2=0%)(N=8, RR:1.22, 95% CI: 1.14 to 1.30, P<0.00001, I2=0%). On the other hand, RSI(N=2, MD : -4.29, 95% CI: -4.71 to -3.86, I2=94%), RFS(N=2, MD : -3.28, 95% CI: -3.71 to -2.85, I2=96%), and Incidence of Adverse Reactions(N=5, RR: 0.32, 95% CI: 0.17 to 0.61, I2=0%) in the experimental group were lower than that of the control group. Conclusion : Treatment with Banhahubak-tang was found to be effective on GERD. However the results might be biased because of the poor quality and small sample size of the included RCTs.

  • Purpose: This study aimed to examine the effects of non-pharmacological sleep intervention programs in improving sleep quality among older adults in long-term care facilities. Methods: A literature search and selection was performed on nine different databases using the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Overall, 14 studies met the inclusion criteria and were systematically reviewed. For the meta-analysis, the effect size was estimated using the random-effects model in Review Manager (RevMan) desktop version 5.4 of the Cochrane Library. Results: The meta-analysis of overall non-pharmacological interventions obtained a total effect size of 1.0 (standardized mean difference [SMD]=1.0, 95% confidence interval [CI]: 0.64~1.35), which was statistically significant (Z=5.55, p<.001). The most frequently studied non-pharmacological intervention was aroma therapy, with an effect size of 0.61 (SMD=0.61, 95% CI: 0.14~1.08), which was statistically significant (Z=2.55, p=.010). In the subgroup analysis, group-based interventions, interventions for >4 weeks, and untreated control studies were more effective. Conclusion: This study confirms that non-pharmacological interventions are effective in improving sleep quality among older adults in long-term care facilities. However, the sample size was small and the risk of bias in assessing the interventions of individual studies was unclear or high, thereby limiting the generalizability of the results. Further reviews that evaluate randomized control trials, evidence-based interventions that consider older adult participants' physical activity levels, different intervention methods and durations, and different control group intervention types are needed to obtain more conclusive evidence.

  • Purpose: Recently, oxytocin has been introduced experimentally as a pharmacological treatment for post-traumatic stress disorder (PTSD). This study attempted to investigate the possibility of oxytocin as a treatment option for patients with PTSD by examining its dose, interval, and effectiveness in patients with PTSD. Methods: A systematic review was done on articles published from 1967 to 2020 using the PubMed, PsycINFO, and Cochrane databases. Our inclusion criteria were 1) subjects 18 years of age or older diagnosed with PTSD or exposed to a traumatic event that met criterion A of the Diagnostic and Statistical Manual of Mental Disorders (DSM) for PTSD, 2) oxytocin was administered at least once, 3) clinical trials, and 4) studies published in Korean or English. Two independent researchers reviewed 22 articles and recorded the contents. The risk of bias was evaluated to determine the quality of the reviewed article. Results: The parameters for evaluating the effectiveness of oxytocin were identified as socio-behavioral measures in 11 articles, neuronal imaging in 9, and biomarkers in 4. In 5 papers, oxytocin was administered multiple times. Socio-behavioral measures were improved in 3 out of 5 studies in which oxytocin was administered multiple times. In 2 studies in which prolonged exposure treatment and nasal oxytocin administration were combined for 10 weeks, patient symptoms were decreased compared to the control group. Conclusion: The possibility of oxytocin as an adjuvant treatment for PTSD psychotherapy was confirmed. Further studies are necessary to evaluate the long term effectiveness of administering oxytocin multiple times combined with psychotherapy.
