  • PURPOSE: This study was a systematic review and meta-analysis of the literature comparing the differences between task-oriented treadmill training and general treadmill training for stroke patients. METHODS: Literature published in the Cumulated Index to Nursing and Allied Health Literature (CINAHL), Embase, Physiotherapy Evidence Database (PEDro), and PubMed was reviewed. A total of 1,163 studies were initially retrieved, of which eight articles were included in the final review. A quality assessment of the included studies was conducted using the Risk of Bias (RoB) 2.0 tool, and Duval and Tweedie's trim and fill method was used to evaluate publication bias. Data analysis was performed using R studio 4.2.1. RESULTS: According to the quality assessment using RoB 2.0, three articles were evaluated as low risk, two as of some concern, and three as high risk. The overall effect size of task-oriented tradmill training was .35. Regarding gait function, the values were .76, .25, and .40, respectively, for gait endurance, gait speed, and gait pattern. According to Duval and Tweedie's trim and fill method, no publication bias was observed. CONCLUSION: Study findings indicate that task-oriented treadmill training is the most effective intervention for improving gait endurance in patients with stroke. Therefore, applying this intervention to patients with stroke in the community is recommended.

  • Purpose: This study aimed to summarize the current evidence on the effects of nonpharmacological interventions on psychological health outcomes for women with high-risk pregnancies due to conditions such as preeclampsia, gestational diabetes, or preterm labor. Methods: The following databases were searched from January 2000 to December 2020: PubMed, Ovid Embase, CINAHL, Web of Science, DBpia, RISS, and KISS. Two investigators independently reviewed and selected articles according to the inclusion/exclusion criteria. RoB 2 and the ROBINS-I checklist were used to evaluate study quality. Results: Twenty-nine studies with a combined total of 1,806 pregnant women were included in the systematic review and meta-analysis. Psychological health improvements were found in women with preeclampsia (Hedges' g=-0.67; 95% confidence interval [CI], -0.91 to -0.44), gestational diabetes (Hedges' g=-0.38; 95% CI, -0.54 to -0.12), and preterm labor (Hedges' g=-0.73; 95% CI, -1.00 to -0.46). The funnel plot was slightly asymmetrical, but the fail-safe N value and the trim-and-fill method showed no publication bias. Conclusion: Nonpharmacological interventions for women with high-risk pregnancies due to conditions such as preeclampsia, gestational diabetes, and preterm labor can improve psychological parameters such as anxiety, stress, and depression. Nurses can play a pivotal role in the nursing management of pregnant women with high-risk conditions and apply various types of nonpharmacological interventions to meet their needs in uncertain and anxious times during pregnancy.

  • Our aim was to access the association between recreational physical activity (RPA) and risk of ovarian cancer (OC). The studies were retrieved from the PubMed and Embase databases up to February 20th, 2014. Risk ratios (OR) and 95% confidence intervals (CI) were used to estimate effect sizes. Random-effects or fixed-effects models were used to pool the data. The trim and fill method was applied for sensitivity analysis. Begg's rank correlation test and Egger's regression asymmetry test were employed to assess the publication bias. A total of 6 studies (435398 participants including 2983 OC patients) were included in this meta-analysis. The overall estimate indicated that there was weakly inverse association between RPA and OC risk (RR=0.90, 95%CI: 0.72-1.12, p=0.335). Meanwhile, for prospective cohort studies, a result consistent with the overall estimate was obtained (RR=1.12, 95% CI: 0.88-1.42, p=0.356). However, for case control studies, the pooled estimate of RR was 0.76 (95%CI: 0.64-0.90, p=0.002), indicating a clear significant association between RPA and OC risk. In addition, the sensitivity analysis indicated a significant link between RPA and risk of OC after removing Lahmann's study (RR=0.80, 95% CI: 0.68-0.93, p=0.004). No significant publication bias was found (Begg's test: p=1.00; Egger's test: p=0.817). In conclusion, our meta-analysis indicated a weakly inverse relationship between RPA and the occurrence of OC.

  • Purpose: The purpose of this study was to review and identify factors relevant to workplace bullying in nursing. Methods: Twenty-three studies that met the criteria were selected from a sample of twenty-six studies. These articles were retrieved from a central literature databases (N=13,241). The total correlational effect size (ESr) for each related factor was calculated from Fisher's Zr. A funnel plot inspection (similar to scatter plot) with a trim-and-fill method was used to assess the publication bias of the meta-analyzed studies. Results: From the systematic review, fifty-one factors were identified as having an influencing effect. Fourteen factors (five individual and nine organizational factors) were eligible for meta-analysis. The individual factors included, self-esteem (ESr=-.31), psychological capital (ESr=-.26), and marital status (ESr=-.06) which were significantly correlated with workplace bullying. Organizational factors included, organizational tolerance (ESr=.48), supervisor incivility (ESr=.47), job stress (ESr=.46), group morale (ESr=-.36), group support (ESr=-.35), supervisor leadership (ESr=-.35), group identity (ESr=-.33), and structural empowerment (ESr=-.27). These factors were significantly correlated with workplace bullying. There were no publication biases except for both individual and organizational factors. Conclusion: Organizational factors have more of an greater impact than individual factors on workplace bullying. The results of this study support the need for intervention at the organizational level.

  • The purpose of this meta-analysis was to investigate the anti-hepatotoxic effect of ginseng in rats induced with CC14 or TCDD, the toxicities that cause liver damages. Primary studies were collected from the ScienceDirect database, the DBpia, and the KISS. The data on the effect factors in plasma and in enzyme are listed as many as possible: The effect factors were alanine transaminase(ALT), aspartate transaminase(AST), liver aminopyrine N-demethylase(AD), liver aniline hydroxylase(AH), liver 3,4-Methylenedioxyamphetamine(liver MDA), cytochrome P450(P450), serum alkaline phosphatase(ALP), serum lactate dehydrogenase(LDH), cytochrome b5(Cyto b5), glutathione reductase (GR), Liver glutathione S-transferase(GST), liver glutamyltransferase (GT), Liver($\gamma$-GCS), serum liver 3,4-Methylenedioxyamphetamine(serum MDA), serum sorbitol dehydrogenase(SDH), serum total protein(TP), and serum $\gamma$-glutamyltransferase($\gamma$-GT). In order to investigate the effect of ginseng, the standard mean difference(HG) between the group of rats induced with toxicity(RH) and the group of rats induced with ginseng(RHG) were combined, and the significance of HGs were tested. The combined HGs checked the biases caused by heterogeneity among studies and the publication biases. Then they were adjusted by using the random effect model and trim and fill method. Although the publication biases were assumed, among all plasma factors the HGs of ALT, AST, serum MDA, SDH, TP, and $\gamma$-GT were significant, and among all enzyme factors the HGs of liver MDA, Cyto b5, GR, GST, and GT were significant. The treatment with ginseng significantly affected the plasma and enzyme levels in rats induced with toxicity.

  • The aim of this meta-analysis was to systematically investigate the anti-hepatotoxic effect of ginseng in rats induced toxicity which damage to liver. Primary researches were gained on the ScienceDirect database, the DBpia, and the KISS, and the data about the effect factors in plasma and in enzyme were listed as many as possible. The effect factors were alanine transaminase (ALT), aspartate transaminase (AST), liver aminopyrine N-demethylase (AD), liver aniline hydroxylase (AH), liver 3,4-Methylenedioxyamphetamine (liver MDA), cytochrome P450 (P450), serum alkaline phosphatase (ALP), serum lactate dehydrogenase (LDH), cytochrome b5 (Cyto b5), glutathione reductase (GR), Liver glutathione S-transferase (GST), liver glutamyltransferase (GT), Liver (${\gamma}-GCS$), serum liver 3,4-Methylenedioxyamphetamine (serum MDA), serum sorbitol dehydrogenase (SDH), serum total protein (TP), serum ${\gamma}-glutamyltransferase$ (${\gamma}-GT$). To investigate the effect of ginseng, the mean difference (MD) between the group of rats induced by toxicity (RH) and the group of rats induced by toxicity with ginseng (RHG) were combined, and the significance of MDs were tested. The combined MDs were checked the biases caused by heterogeneity among studies and the publication biases, and adjusted by using random effect model and trim and fill method, respectively. The effect about ALT, AST, ALP, LDH, SDH, TP and ${\gamma}-GT$ in plasma factors were significant, and about AD, liver MDA, P450, Cyto b5, GR, GST, GT and ${\gamma}-GCS$ in enzyme factors were significant. The treatment with ginseng supplementation was significantly effected on plasma and enzyme factors of damaged-rats.

  • Objective : Mechanical thrombectomies with balloon-guide catheters (BGC) are thought to improve successful recanalization rates and to decrease the incidence of distal emboli compared to thrombectomies without BGC. We aimed to assess the effects of BGC on the outcomes of mechanical thrombectomy in acute ischemic strokes. Methods : Studies from PubMed, EMBASE, and the Cochrane library database from January 2010 to February 2018 were reviewed. Random effect model for meta-analysis was used. Analyses such as meta-regression and the "trim-and-fill" method were additionally carried out. Results : A total of seven articles involving 2223 patients were analyzed. Mechanical thrombectomy with BGC was associated with higher rates of successful recanalization (odds ratio [OR], 1.632; 95% confidence interval [CI], 1.293-2.059). BGC did not significantly decrease distal emboli, both before (OR, 0.404; 95% CI, 0.108-1.505) and after correcting for bias (adjusted OR, 1.165; 95% CI, 0.310-4.382). Good outcomes were observed more frequently in the BGC group (OR, 1.886; 95% CI, 1.564-2.273). Symptomatic intracranial hemorrhage and mortality did not differ significantly with BGC use. Conclusion : Our meta-analysis demonstrates that BGC enhance recanalization rates. However, BGC use did not decrease distal emboli after mechanical thrombectomies. This should be interpreted with caution due to possible publication bias and heterogeneity. Additional meta-analyses based on individual patient data are needed to clarify the role of BGC in mechanical thrombectomies.

  • Purpose : The purpose of this study was to investigate the meta-analysis on the effects of action observation training on stroke patients' walking. Methods : Domestic databases (DBpia, KISS, NDSL, and RISS) were searched for studies that conducted randomized controlled trials (RCTs) associated with action observation training in adults after stroke. The search outcomes were items associated with the walking function. The 18 studies that were included in the study were analyzed using R meta-analysis. A random-effect model was used for the analysis of the effect size because of the significant heterogeneity among the studies. Sub-group and meta-regression analysis were also used. Egger's regression test was conducted to analyze the publishing bias. Cumulative meta-analysis and sensitivity analysis were also done to analyze a data error. Results : The mean effect size was 2.77. The sub-group analysis showed a statistical difference in the number of training sessions per week. No statistically significant difference was found in the meta-regression analysis. Publishing bias was found in the data, but the results of the trim-and-fill method showed that such bias did not affect the obtained data. Also, the cumulative meta-analysis and sensitivity analysis showed no data errors. Conclusion : The meta-analysis of the studies that conducted randomized clinical trials revealed that action observation training effectively improved walking of the chronic stroke patients.
