  • Objective: Atrial fibrillation (AF) guidelines have been published in the USA and Europe. Recently, the USA and Europe have updated their guidelines, respectively. These new AF guidelines help in addressing key management issues in clinical situations. This study, therefore, systematically compared guidelines for rate and rhythm control pharmacotherapy of patients with AF between the USA (American College of Cardiology and American Heart Association, ACC/AHA) and Europe (European Society of Cardiology, ESC). Methods: This study investigated and compared American guidelines (2014) and European guidelines (2010 and 2012). Results: Generally, there are four meaningful differences between ACC/AHA and ESC guidelines. Important differences are treatment classification system, level of recommendation, drug list, and dosage. In addition, ACC/AHA described pharmacokinetic drug interactions for antiarrhythmic drugs. ESC emphasized ECG and atrioventricular nodal slowing as feature of antiarrhythmic drugs. Conclusion: This research addresses important use of anti-arrhythmic drugs and movement to accept recent recommendations in Korea. For the successful application of the guidelines, a role of pharmacists is crucial in clinical situation.

  • Purpose: This study aimed to compare the effects of simulation integrated with problem based learning (S-PBL) according to the sequences of problem-based learning (PBL) and high fidelity simulation training (HFS) on knowledge, clinical performance, clinical judgment, self-confidence, and satisfaction in fourth-grade nursing students. Methods: In this randomized crossover design study, four S-PBLs on medical-surgical nursing were applied alternatively to two randomly-assigned groups of 26 senior nursing students for 8 weeks. The collected data were analyzed using an independent t-test. Results: The method of administering PBL prior to HFS led to significantly higher scores on knowledge (t=2.28, p=.025) as compared to the method of administering HFS prior to PBL. However, the latter method led to significantly higher scores on clinical performance (t=-6.49, p<.001) and clinical judgment (t=-4.71, p<.001) as compared to the method of administering PBL prior to HFS. There were no differences in the effect of the two methods on self-confidence (t=1.53, p=.128) and satisfaction (t=1.28, p=.202). Conclusion: The integration sequences of S-PBL was associated with different learning outcomes. Therefore, when implementing S-PBL, it is necessary to consider the educational goal to executes an appropriate sequence of integration.

  • This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.

  • Several methods have been used in the detection of Helicobacter pylori (H. pylori) which was believed to be a pathogenic organism causing chronic gastritis, benign peptic ulcer, gastric carcinoma or malignant lymphoma. Even though several methods were introduced for detection of H. pylori in stomach, there were controversies in their sensitivities and specificities. This experiment were designed to study the comparative analysis of staining methods (hematoxylin and eosin (H&E), Giemsa, Warthin-Starry and immunohistochemical stain) to dectect H. pylori in the gastric mucosa. The results were as follows. Average density score of H. pylori classified by Genta were 2.29 in Warthin-Starry stain, 2.19 in Giemsa stain, 1.34 in immunohistochemical stain and 0.98 in H&E stain. By comparison between inflammatory degree by Sydney system and result of Warthin-Starry stain, the detection rate and densities of H. pylori were increased from mild (61.5% and 0.8), moderate (90.4 and 2.1), and severe (100% and 3.2). From the above findings, Warthin-Starry stain is useful method for detection of H. pylori in gastric mucosa.

  • In Korea, the Mycobacterium tuberculosis K-strain is the most prevalent clinical isolates and belongs to the Beijing family. In this study, we conducted comparative porteomics of expressed proteins of clinical isolates of the K-strain with H37Rv, H37Ra as well as the vaccine strain of Mycobacterium bovis BCG following phagocytosis by the human monocytic cell line U-937. Proteins were analyzed by 2-D PAGE and MALDI-TOF-MS. Two proteins, Mb1363 (probable glycogen phosphorylase GlgP) and MT2656 (Haloalkane dehalogenase LinB) were most abundant after phagocytosis of M. tuberculosis K-strain. This approach provides a method to determine specific proteins that may have critical roles in tuberculosis pathogenesis.

  • Purpose: This study aimed to assess and compare the effectiveness of various fall prevention interventions in hospitals through a network meta-analysis. Methods: A network meta-analysis was conducted using the "netmeta" package in R software (v4.1), employing a frequency method. Odds ratios of fall rates and injurious fall rates were utilized to confirm the effects of interventions for fall prevention. Comparative rankings of these interventions were determined using cumulative probability (P-score). Results: Comparative rankings via cumulative probability (P-scores) revealed individualized education as the most effective intervention for fall incidence (P-Score 87.8%). Followed by fall-preventing sensors (60.9%), multicomponent interventions (47.4%), usual care (33.2%), and environmental modification (20.7%). For fall-related injuries, individualized education ranked highest (P-Score 97.1%), followed by multicomponent interventions (76.0%), usual care (47.6%), environmental modification (24.2%), and fall-preventing sensors (5.1%). Conclusion: This study provides valuable insights into the relative effectiveness of diverse interventions in preventing fall incidence through network meta-analysis. The findings aim to support nurses in making informed decisions when implementing fall prevention strategies in clinical practice.

  • Objectives: In this preliminary study, we investigated the clinical characteristics of patients who were first diagnosed with psychotic disorder and explored the impact of the adherence to antipsychotics on long-term medical use. Methods: All national health insurance claims related to psychotic disorders including gender, age, income, and drug compliance, from January 1, 2008 to December 31, 2015, were examined. With trend test using Medication Possession Ratio (MPR), we compared the medical use between the compliant group (MRP≥0.8) and the comparative non-compliant group (0.2≤MPR<0.8). Results: Among 28,095 participants in total, 16,239 patients (57.8%) were diagnosed as schizophrenia; the 30s were the most common (n=7,151, 25.5%). Drug compliance was generally low regardless of the diagnosis and was the lowest among 20s with the 40-60% range of income. The compliant group showed lower psychiatric and medical use than the comparative group in the following years (p<0.0001). Conclusion: These findings suggest that patients in the 20s and 30s with the 40-60% range of income, who are diagnosed with schizophrenia at the first psychiatric visit, may need more clinical and political attention. The results also emphasize the importance of initial drug adherence to antipsychotics in reducing long-term psychiatric costs.
