  • Purpose: The current challenges faced by nurses in providing high quality and evidence-based practice (EBP) supported care require profound changes in nursing education. To understand the changes needed to strengthen EBP education, the researchers examined EBP self-efficacy, course needs, barriers, and facilitators for academic faculty and clinical nurse preceptors to teach EBP in undergraduate nursing curricula. Methods: For this study, mixed-method approach was used with survey data collected from 73 academic faculty members from 54 universities. Further, 17 clinical nurse preceptors in three academic hospitals provided qualitative data for exploration of barriers and facilitators to teaching EBP. Data analysis used SPSS/WIN 21.0 and content analysis. Results: Quantitative data showed that although the overall level of self-efficacy among faculty was moderate, the implementation levels were relatively low. Most faculty members agreed with the need to integrate EBP courses into undergraduate nursing curricula. The qualitative data showed that the barriers to teaching EBP were lack of knowledge, skill, and initial investment for teaching EBP; hierarchical, rules-oriented nursing culture; potential learner overloads in processing EBP; limited research dissemination and application. Facilitators were identified as the importance of EBP to the profession of nursing; collaboration in schools and hospitals; and continuing education in teaching/utilizing EBP. Conclusion: The findings indicate that for successful integration of EBP ni nursing education there is a need for faculty training and integrated EBP courses.

  • This study aimed was done to analyze recent trends in nursing research published in the Journal of Korean Academy of Nursing by focusing on the content of nursing interventions and their level of evidence. Methods: A total of 209 studies published between 2007 and 2008 were reviewed using analysis criteria developed by the researchers. Results: The number of quantitative studies was greater than that of qualitative studies. There was a slight increase in the number of qualitative studies and studies including elderly populations, which reflects the recent population trend in Korea. More randomized controlled trials with a low risk of bias were needed to support more evidence-based nursing practice. Concerning the low rate of ethical consideration, stricter application of research ethics needs to be encouraged. Conclusion: The findings of this study suggest the recent trends in nursing research and the direction of nursing research and review in the Journal.

  • Objectives: This study is an overview of the meta-analysis and systematic review of randomized controlled trials investigating the clinical effectiveness and safety of pharmacopuncture for patients with stroke. Methods: Core electronic databases were searched from their inception to 21 May 2019. A measurement tool to assess systematic reviews (AMSTAR 2) was applied to screen high-quality studies. The results of these studies were summarized, and additional meta-analysis was conducted. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to evaluate the certainty of evidence. Results: Sixteen studies met eligibility criteria. Four were excluded owing to insufficiency of AMSTAR 2 or low data reliability. The finally selected 12 studies were about pharmacopuncture using either a single herb extract, such as Dengzhan xixin, Sanch, Ginkgo biloba, or Acanthopanax, or a mixture of herbs, such as Compound danshen, Shenxiong, Xingnaojing, or Mailuoning. Most of the patients were from China, with acute ischemic stroke. All the studies using a pharmacopuncture versus a non-pharmacopuncture design reported the significant superiority of pharmacopuncture on every outcome measure. On the other hand, in a few studies, pharmacopuncture was inferior to active control in improving neurological deficit. Few studies reported adverse events. Conclusions: It is difficult to apply the results of this study directly to Korea, because the level of evidence is generally low and the clinical settings and social acceptance of pharmacopuncture therapy differ in Korea and China. Further studies are warranted to confirm the domestic applicability of evidence generated in China and to create evidence that supports the domestic situation.

  • Purpose: Numerous observational epidemiological studies have evaluated associations between breastfeeding and the risk of childhood Hodgkin lymphoma; however, the existing results are inconsistent. We therefore conducted a systematic review and meta-analysis. Methods: Medical literature was searched in the Pubmed and Embase databases to identify all English-language relevant studies up to April 10, 2013. Reference lists were thereafter hand-searched for additional articles. Studies that reported relative risk ratios (RRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were included. This meta-analysis was conducted in accordance with the guidelines for the meta-analysis of observational studies in epidemiology. Results: We finally included 10 case-control studies in our meta-analysis, involving 1,618 childhood Hodgkin lymphoma cases and 8,181 controls. Overall, we did found a borderline significant association between breastfeeding and reduced risk of childhood Hodgkin lymphoma comparing ever breastfed children to never breastfed children (pooled OR =0.79; 95%CI, 0.58-1.08; P=0.13), with limited evidence for between-study heterogeneity (P =0.12, $I^2$ = 35.70%). Conclusion: There is limited evidence for an inverse association between breastfeeding and risk of childhood Hodgkin lymphoma.

  • This meta-analysis was performed to assess the implementation effects of clinical pathways in patients with gastrointestinal cancer. A comprehensive search was conducted in the Cochrane Library, PubMed, EMBASE, Web of Science and Chinese Biomedical Literature Database (from inception to May 2014). Selection of studies, assessing risk of bias and extracting data were performed by two reviewers independently. Outcomes were analyzed by fixed-effects and random-effects model meta-analysis and reported as mean difference (MD), standardized mean difference (SMD) and odds ratio (OR) with 95% confidence intervals (CI). The Jadad methodological approach was used to assess the quality of included studies and the meta-analysis was conducted with RevMan 5.1 software. Nine citations (eight trials) involving 642 patients were included. The aggregate results showed that a shorter average length of stay [MD = -4.0; 95% CI (-5.1, -2.8); P < 0.00001] was observed with the clinical pathways as compared with the usual care. A reduction in inpatient expenditure [SMD = -1.5; 95% CI (-2.3, -0.7); P = 0.0001] was also associated with clinical pathways, along with higher patient satisfaction [OR = 4.9; 95% CI (2.2, 10.6); P < 0.0001]. Clinical pathways could improve the quality of care in patients with gastrointestinal cancer, as evidenced by a significant reduction in average length of stay, a decrease in inpatient expenditure and an improvement in patient satisfaction. Therefore, indicators and mechanisms within clinical pathways should be a focus in the future.

  • Temperature-dependent changes in near-infrared (NIR) spectra have been measured for oleic acid, and nonanoic acid in the pure liquid state. Particular attention has been paid to the 5400-4800 cm$\^$-1/ region where a number of combination bands appear. The NIR spectra of oleic acid show that a band at 5303 cm$\^$-1/ increases with temperature while that at 5270 cm/sup-1/ decreases. It ha been found from their second derivative spectra that these spectral changes take place stepwisely with two break points at 30 and 53$\^{C}$, which correspond to the phase transition temperatures oleic acid reported previously. Principle component analysis (PCA) has been carried out for the NIR spectra of oleic acid in the 5400-4800 cm$\^$-1/ region measured over a temperature range of 15-80$\^{C}$. core plots of the first and second principal components (PCs) show that the NIR spectra are classified into three groups; the spectra measured in the temperature range of 15-30$\^{C}$, those in the range of 31-53$\^{C}$, and those in the range of 54-80$\^{C}$. These temperature ranges correspond to those for quasi-smectic liquid crystal, disordered liquid crystal, and isotropic liquid of oleic acid in the pure liquid state. In other words, PCA provides unambiguous evidence for the phase transitions. similar studies have been carried out for petroselinic acid and nonanoic acid in the pure liquid states, but they do not show any evidence for phase transitions.

  • Background: An excessive pronated foot is defined as a flattening or complete loss of the medial longitudinal arch. Excessive foot pronation is considered to have high risk factors of overuse injuries in the lower limb. Various treatments have been investigated in attempts to control excessive pronation. Objects: This meta-analysis identifies the effects of an anti-pronation taping technique using different materials. Methods: The electronic databases used include MEDLINE, the Physiotherapy Evidence Database (PEDro), Science Direct, the Korean Studies Information Service System (KISS), the Research Information Sharing Service (RISS), the Korea National Library, and the Korean Medical Database (studies published up to July 31, 2019). The database search used the following keywords: "foot drop" OR "foot arch" OR "foot pronation" OR "flat foot (pes planus)" AND "taping" OR "support." Eight eligible studies were analyzed to determine the effectiveness of anti-pronation taping in study and control groups. Results: The overall random effect size (Hedges'g) of the anti-pronation taping technique was 0.147 (95% confidence interval [CI]: -.214 to .509). When the effect (Hedges' g) was compared by the type of tape material, rigid tape (RT; Lowdye taping) was .213 (95% CI: -.278 to .704) and kinesiotape (KT; arch support taping) was -.014 (95% CI: -.270 to .242). Based on this meta-analysis, it was not possible to identify the extent to which anti-pronation taping was effective in preventing navicular drop, improving balance, or changing foot pressure. Only three of the eight eligible studies applied KT on excessive pronated feet, and the outcome measure areas were different to those of the RT studies. The KT studies used EMG data, overall foot posture index (FPI) scores, and rear foot FPI scores. In contrast, the RT studies measured navicular heights, various foot angles, and foot pressure. Conclusion: This review could not find any conclusive evidence about the effectiveness of any taping method for patients with pronated feet. Future studies are needed to develop the anti-pronation taping technique based on the clinical scientific evidence.

  • Background: Postoperative pain management is crucial for patients undergoing total knee arthroplasty (TKA). There have been many recent clinical trials on post-TKA peripheral nerve block; however, they have reported inconsistent findings. In this meta-analysis, we aimed to comprehensively analyze studies on post-TKA analgesia to provide evidence-based clinical suggestions. Methods: We performed a computer-based query of PubMed, Embase, the Cochrane Library, and the Web of Science to retrieve related articles using neurothe following search terms: nerve block, nerve blockade, chemodenervation, chemical neurolysis, peridural block, epidural anesthesia, extradural anesthesia, total knee arthroplasty, total knee replacement, partial knee replacement, and others. After quality evaluation and data extraction, we analyzed the complications, visual analogue scale (VAS) score, patient satisfaction, perioperative opioid dosage, and rehabilitation indices. Evidence was rated using the Grading of Recommendations Assessment, Development, and Evaluation approach. Results: We included 16 randomized controlled trials involving 981 patients (511 receiving peripheral nerve block and 470 receiving epidural block) in the final analysis. Compared with an epidural block, a peripheral nerve block significantly reduced complications. There were no significant between-group differences in the postoperative VAS score, patient satisfaction, perioperative opioid dosage, and rehabilitation indices. Conclusions: Our findings demonstrate that the peripheral nerve block is superior to the epidural block in reducing complications without compromising the analgesic effect and patient satisfaction. Therefore, a peripheral nerve block is a safe and effective postoperative analgesic method with encouraging clinical prospects.
