  • Background: Senecavirus A (SVA), a member of the family Picornaviridae, is newly discovered, which causes vesicular lesions, lameness in swine, and even death in neonatal piglets. SVA has rapidly spread worldwide in recent years, especially in Asia. Objectives: We conducted a global meta-analysis and systematic review to determine the status of SVA infection in pigs. Methods: Through PubMed, VIP Chinese Journals Database, China National Knowledge Infrastructure, and Wanfang Data search data from 2014 to July 26, 2020, a total of 34 articles were included in this analysis based on our inclusion criteria. We estimated the pooled prevalence of SVA in pigs by the random effects model. A risk of bias assessment of the studies and subgroup analysis to explain heterogeneity was undertaken. Results: We estimated the SVA prevalence to be 15.90% (1,564/9,839; 95% confidence interval [CI], 44.75-65.89) globally. The prevalence decreased to 11.06% (945/8,542; 95% CI, 28.25-50.64) after 2016. The highest SVA prevalence with the VP1-based RT-PCR and immunohistochemistry assay was 58.52% (594/1,015; 95% CI, 59.90-83.96) and 85.54% (71/83; 95% CI, 76.68-100.00), respectively. Besides, the SVA prevalence in piglet herds was the highest at 71.69% (119/166; 95% CI, 68.61-98.43) (p < 0.05). Moreover, our analysis confirmed that the subgroups, including country, sampling year, sampling position, detected gene, detection method, season, age, and climate, could be the heterogeneous factors associated with SVA prevalence. Conclusions: The results indicated that SVA widely exists in various countries currently. Therefore, more prevention and control policies should be proposed to enhance the management of pig farms and improve breeding conditions and the environment to reduce the spread of SVA.

  • Objectives To evaluate the evidence supporting the efficacy and safety of electroacupuncture for lumbar spinal stenosis. Methods We searched eight electronic databases (PubMed, EMBASE, Cochrane Library, Chinese Academic Journals, Research Information Sharing Service, ScienceOn, KMBASE, DBpia) and related two journals up to March 2023. We included randomized controlled trials of testing electroacupuncture for lumbar spinal stenosis patients. The methodological quality of relevant randomized controlled trials assessed by the Cochrane risk of bias tool. Results Among 90 articles that were searched, seven randomized controlled trials involving 474 participants were finally selected in this systematic review. Electroacupuncture was more effective on lumbar spinal stenosis compared with other treatments including analgesics, acupuncture, bed rest and exercise therapy, but showed ambiguous effect compared with physical therapy. Most of the side effects and adverse reactions were reported as minor and temporary. Conclusions Electroacupuncture for lumbar spinal stenosis was more effective than analgesics, acupuncture, bed rest and exercise therapy. In terms of safety, it was limited because there are many papers that do not mention side effects and adverse reactions related to electroacupuncture. Additional studies are needed to determine the effect of electroacupuncture on lumbar spinal stenosis.

  • Purpose : This study investigates the effectiveness of digital therapy for stroke patients in Korea. Methods : A comprehensive database search was performed using KCI, Science on, e-article, RISS, KISS and Korea OpenMed databases for randomized controlled trials (RCTs) that studied the effects of digital therapy on patients who had a stroke. This study includes RCTs published from January 2000 to July 15, 2022, which fulfilled the inclusion and exclusion criteria. A total 697 studies were screened and 30 studies were included in the final analysis. Methodological quality was assessed with the Cochrane's RoB (risk of bias) tool. Meta-analysis was performed using CMA 4.0 software. Results : A total of 56 effect sizes were calculated from the 30 selected studies. As a result of the analysis, the overall effect size of digital therapy was .59 (95 % CI=.43-.74). When classified according to type of intervention, VR (virtual reality) (g=.58, 95 % CI=.40-.75), and CACR (computer assisted cognitive rehabilitation) (g=.62, 95 % CI=.30-.95) were statistically significant. VR showed medium to large effect sizes in cognitive function (g=.78, 95 % CI=.20-1.37), psychosocial function (g=.63, 95 % CI=.20-1.07), and physical function (g=.61, 95 % CI=.38-.83). In the CACR, there was a large effect size in cognitive function (g=.84, 95 % CI=.52-1.15), but there was no significant difference in psychosocial function. Also, there was no significant difference between the two interventions in activities of daily living and no significant difference in the effect size of both interventions according to the intervention session. Furthermore, medium to large effect sizes were found for subacute and chronic stroke patients according to the duration of disease. Conclusion : This study presents evidence that digital therapy has a positive effect on various functions of stroke patients in Korea. The researchers expect to actively accept the new paradigm of digital therapy and continue to apply digital therapy in clinical practice.

  • Objectives: Sarcopenia is an age-associated skeletal muscle disorder that can profoundly impact the health of elderly people. However, the efficacy of herbal medicine in sarcopenia is uncertain. This review aims to investigate evidence of the effect of herbal medicine on sarcopenia. Methods: We systematically searched 12 electronic databases for relevant randomized controlled trials (RCTs). Only trials that met the inclusion criteria were selected, and the characteristics of the included studies were extracted and synthesized in a narrative manner. The quality of the included studies was assessed using Cochrane's Risk of Bias (RoB) 2.0 tool. Results: 7 RCTs involving 672 participants with sarcopenia met the inclusion criteria. The intervention combining herbal medicine and conventional treatment (i.e., exercise, nutritional support) had a significant therapeutic effect compared with the conventional treatment, showing improvement in muscle strength (i.e., grip strength), muscle mass (i.e., appendicular skeletal muscle mass index), and physical function (i.e., gait speed, short physical performance battery, and timed up and go test). However, the methodological quality of the included RCTs was relatively low due to their high RoB, making it difficult to evaluate the efficacy of herbal medicine in sarcopenia. In terms of safety, several adverse events were reported. Conclusion: This review suggests that herbal medicine has a positive effect on muscle strength, muscle mass, and physical performance in elderly patients with sarcopenia, but there is a clear need for further research in this area.

  • To investigate the change of nitric oxide(NO), copper, and zinc in serum on smoking and alcohol ingestion in young adults, this study was performed in a cross-sectional study in 127 healthy men in Korea who had HBsAg(-), HCVAb(-), and no symptomatic liver, heart, gastrointestinal, chronic diseases, and inflammatory sign(lower than 10,000 white blood cell count in CBC). At the men's entry into the study, blood samples were drawn from each subject and immediately centrifuged for analysis of NO, copper, and zinc. Each man completed a questionnaire that provided information on smoking, alcohol intake and present and past medical history NO was analyzed by HPLC(Green et al., 1982), copper and zinc by atomic absorption spectrophotometer with air-acetylene flame and total cholesterol(TC) by Spectrum EPX. Smoking(number of cigarettes per day and pack-year) and alcohol intake was grouped fertile. Copper was adjusted for age and zinc and for age and TC. NO, copper, and zinc on smoking and alcohol ingestion were analyzed in general linear models, respectively. NO, copper and zinc in serum did not show statistical differences between non-smoking and high-smoking group and no-alcohol intake and high-alcohol intake group. This study suggested that copper, zinc, and NO was not. good biological marker for early effect by smoking and alcohol intake in young adults. However, selection bias should be considered in evaluation of this result. A large prospective study will be needed in advance on usefulness of copper, zinc, and NO as a marker for risk factors and early change of atherosclerosis.

  • 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.
