When standardized patients (SPs) are used for educational purposes, the authenticity of role play and the quality of feedback are essential requirements of SPs. This study was conducted to investigate medical students' assessment of SPs and to identify the components of SPs' performance that were most strongly correlated with patient-physician interaction score. One hundred and forty-two fourth-year medical students were asked to complete the Maastricht Assessment of Simulated Patients (MaSP) at the end of a clinical performance examination. SPs evaluated the patient-physician interactions using a 4-point Likert scale (1=poor to 4=excellent). Medical students' assessment of SPs using the MaSP was positively correlated with patient-physician interactions (r=0.325, p<0.01). Items addressing the authenticity of role play (e.g., "SPs appear authentic," "SPs might be real patients," and "SPs answer questions in a natural manner") were closely correlated with patient-physician interactions (p<0.001, p=0.027, and p=0.017, respectively). These results showed that the MaSP appears to be a useful instrument for evaluating SPs' performance and that the authenticity of SPs' performance was positively correlated with medical students' interactions. In order to improve patient-physician interactions, medical students should be given opportunities to practice their skills with SPs who have been trained to portray patients with a specific condition in a realistic way.

Objective: Assess and evaluate the different indicators of oral health-related quality of life (OHRQoL) among patients treated with clear aligners (CAs) versus those treated with conventional fixed orthodontics (FAs). Methods: An electronic search was performed on the database is Web of Science, Scopus, and Embase databases. Randomized and non-randomized control trials, cross-sectional, prospective cohort and retrospective trials were included. Quality was assessed with risk of bias tool and risk of bias in non-randomised studies. Meta-analyses were performed with random effects models, estimating the standardized and non-standardized mean differences, odds ratio and risk ratio as the measure of effect. The effect on time was determined using a meta-regression model. Results: Thirty one articles were included in the qualitative synthesis and 17 in the meta-analysis. CAs had a significantly lower negative impact on QoL, with an "important" effect size, while the influence of time was not significant. Periodontal indicators plaque index (PI), gingival index (GI), probing depth (PD), and bleeding on probing show significantly better values in patients treated with CAs, with moderate to large effect sizes. PI and GI have a significant tendency to improve over time. In microbiological indicators, CAs present a lower biofilm mass without differences in the percentage of patients with high counts of Streptococcus mutans and Lactobacilli bacteria. The risk of white spot lesion onset is ten times lower in carriers of CAs. Conclusions: Patients wearing CAs show better periodontal indicators, less risk of white spot development, less biofilm mass and a better QoL than patients with FAs.
Background: Detection and treatment of tuberculosis (TB) infection with contact investigation is a key component of TB control program. I evaluated the prevalence and risk factors for TB infection among contacts of recently diagnosed pulmonary TB patients in a tertiary hospital in Korea. Methods: 206 contacts of 90 adult pulmonary TB patients underwent tuberculin skin tests (TST) and chest radiography. The TST results were considered positive with an induration of 10 mm or more, suggesting TB infection. A standardized questionnaire was used to assess risk factors associated with TB infection. Results: TST was positive in 97 of 206 contacts of TB patients (47.1%) and positive rate of TST increased with age. The risk of TB infection was significantly associated with close contact with TB patients (sleeping in the same room) (odd ratio [OR], 4.94; 95% confidence interval [CI], 1.43~17.00). Conclusion: TB infection rate was higher in the elderly, and the risk of TB infection was significantly increased with close contact of TB patients.

Background: Visceral pleural invasion (VPI) is a poor prognostic factor that contributes to the upstaging of early lung cancers. However, the preoperative assessment of VPI presents challenges. This study was conducted to examine intraoperative pleural carcinoembryonic antigen (pCEA) level and maximum standardized uptake value (SUVmax) as predictive markers of VPI in patients with clinical T1N0M0 lung adenocarcinoma. Methods: A retrospective review was conducted of the medical records of 613 patients who underwent intraoperative pCEA sampling and lung resection for non-small cell lung cancer. Of these, 390 individuals with clinical stage I adenocarcinoma and tumors ≤30 mm were included. Based on computed tomography findings, these patients were divided into pleural contact (n=186) and non-pleural contact (n=204) groups. A receiver operating characteristic (ROC) curve was constructed to analyze the association between pCEA and SUVmax in relation to VPI. Additionally, logistic regression analysis was performed to evaluate risk factors for VPI in each group. Results: ROC curve analysis revealed that pCEA level greater than 2.565 ng/mL (area under the curve [AUC]=0.751) and SUVmax above 4.25 (AUC=0.801) were highly predictive of VPI in patients exhibiting pleural contact. Based on multivariable analysis, pCEA (odds ratio [OR], 3.00; 95% confidence interval [CI], 1.14-7.87; p=0.026) and SUVmax (OR, 5.25; 95% CI, 1.90-14.50; p=0.001) were significant risk factors for VPI in the pleural contact group. Conclusion: In patients with clinical stage I lung adenocarcinoma exhibiting pleural contact, pCEA and SUVmax are potential predictive indicators of VPI. These markers may be helpful in planning for lung cancer surgery.
This study aims to find out the standardized test criteria regarding patients with the anterior cruciate ligament damage by identifying the degree of the flexion gap of femur and tibia upon bending of the anterior cruciate ligament in order to carry out the accurate test of such impairment. On the standardized test method and judgement criteria upon the anterior cruciate ligament test using Telos, it has been shown that there was no significant difference in the results according to the position of a fixed roller in the anterior cruciate ligament test for normal patients. However, in a test for patients who had undergone the anterior cruciate ligament reconstruction, it has been shown that the measured values of the anterior cruciate ligament tended to be pushed when the position of a fixed roller was less than 1cm in the test according to the position of a fixed roller of Telos (less than 1cm, more than 3cm), and this was statistically significant. The anterior cruciate ligament test (knee stress test) is a limited method used in orthopedics and rehabilitation medicine, and there have been no standardized test guidelines available yet although numerous ligament measurement tests have been performed. In addition, since the measured values are often different depending on testers even on the test that is expected to give the same result, the reproducibility of the test is still low. Accordingly, it is considered that the criteria for the anterior cruciate ligament test need to be established, and this would contribute to the accuracy of the diagnosis through the accurate test and standardized measurements.
Objective: Colistimethate was first became available in 1950s and used until the early 1980s to treat infections caused by gram-negative bacteria and was abandoned due to its nephrotoxicity and neurotoxicity. However, it was recently reintroduced into the clinical practices due to emergence of multidrug-resistance gram-negative bacteria, particularly Pseudomonas aeruginosa and Acinetobacter baumanii. Therefore, it is increasingly used in the intensive care unit settings as a salvage therapy. This study was designed to investigate the incidence rates and risk factors of acute kidney injury associated with colistimethate by using the standardized definition in critically ill patients. Methods: This study retrospectively reviewed the electronic medical records of 71 adult patients above 18 years old receiving intravenous colistimethate at least 48 hours at intensive care unit, university-affiliated hospital from Nov 2012 to Aug 2013 and excluded patients with end-stage renal disease (ESRD) and required renal replacement therapy before initiation of the colistimethate therapy. Acute kidney injury (AKI) was determined by using the standardized RIFLE criteria, classified with risk, injury, failure, loss and ESRD according to serum creatinine (Scr) levels. Results: Among the 71 patients included in the analysis, AKI developed in 40 patients (56.3%) and 6 patients (8.4%) had irreversible kidney injury. AKI occurred within 5 days in 20 patients (50.0%). Maximum Scr level showed a significant increase in the patients with AKI ($1.92{\pm}0.86mg/dL$ vs. $1.12{\pm}0.46mg/dL$ p=0.001), maximum BUN also increased ($64.2{\pm}28.7mg/dL$ vs. $48.4{\pm}24.9mg/dL$ p=0.017) and minimum creatinine clearance (CLcr) was significantly decreased in the patients with AKI than non-AKI ($34.5{\pm}18.6ml/min$ vs. $64.4{\pm}33.7ml/min$ p=0.185). The patients with AKI had significantly longer duration of colistimethate therapy ($21.1{\pm}17.0$ days vs. $13.0{\pm}11.5$ days, p=0.020) and larger cumulative doses of colistimethate ($6465.9{\pm}4717.0mg$ vs. $4438.1{\pm}3426.7mg$, p=0.040). Conclusion: The incidence and severity of AKI associated with colistimethate in critically ill patients was high and serious. Drug monitoring program should be performed to shorten duration of therapy and reduce cumulative dose from initiation of colistimethate therapy for minimizing AKI of colistimethate.
Purpose: The practical examination portion of the National Dental Licensing Examination (NDLE) is slated to be administered in the latter half of 2021 in the form of a clinical performance examination that comprehensively evaluates the patient-dentist interaction using standardized patients (SPs). The SPs should be equipped with the basic qualities and capacity as evaluators for a fair and reliable administration of the test. Materials and Methods: In this study, we analyzed the existing training materials for SPs who participated in domestic and overseas practical tests for the development of training materials for SPs through seminars and surveys of 11 dentistry schools and colleges. Result: First, SPs should be selected according to the basic quality criteria and capacity, which they must possess, and the preliminary basic training about the details which they must have knowledge of and be provided through videorecorded cases before the implementation of the preliminary field training. Second, the roles of SPs and the calibration process of the evaluation result forms are needed when conducting the preliminary field training for SPs. After watching video-recorded scenario cases, the SPs participate in discussions about the watched videos before proceeding to calibration practices of evaluation result forms. Third, because the Type A questionnaire of the practical examination of the NDLE is dependent on the SPs' capacity and training, the fairness of the practical test is largely dependent on the SPs. Therefore, practicing the roles as evaluators and evaluation training should be provided using practical test items that can improve the reliability of the test and show a high level of reproducibility about the same case. Conclusion: The findings of this study will be utilized for the development of training materials for SPs, so they can participate in the administration of a fair and reliable practical examination of the NDLE.

Purpose: This study was conducted to investigate the effects on problem solving ability and learning satisfaction in nursing students using a teaching method with a standardized patient (SP) receiving blood transfusion. Method: The research design was a quasi-experimental pre-and-post-test control and experimental group for the methodological comparison study. Participants were 43 (Exp.=22, Cont.=21) nursing students in G city. The experimental group participated in the teaching class using SP. The control group received conventional education using a simple model. Data were collected between June 5 and July 15, 2015, through self-report structured questionnaires and data were analyzed using the SPSS/WIN 21.0 program. Results: There were significant differences in the level of problem solving ability (t=-2.75, p=.009), and learning satisfaction (t=-2.53, p=.016) between the experimental and control groups. Conclusion: The research findings indicate that, the teaching method using an SP is more effective in improving nursing students' problem solving ability and learning satisfaction compared to conventional education using a simple model. In the future it is necessary to develop scenarios of various cases and content, and to test their effectiveness.
Purpose: To describe nursing students' perceptions of their experiences on the home visiting simulation in community health nursing practicum. Methods: Descriptive survey method was used to evaluate students' experiences from the home visiting simulation. Results: The simulation was divided into three sections: orientation, facilitating the scenario and debriefing. The orientation was held for fifteen minutes, and four sessions of the simulation were implemented for 180 minutes. Sixty-one nursing students participated (91.8% female) and the mean age was $21.4{\pm}2.4$ years. No one had prior simulation experiences. Participants experienced reflective thinking during the scenario implementation and debriefing session. They perceived the home visiting simulation as an active learning and realistic training environment. However, participants expressed difficulties in focusing on the simulation when their peers played a patient role. In addition, peer patient role-players expressed the role burden. Conclusion: The home visiting simulation is a feasible and effective method for attaining goals a community health nursing clinical course for students. It can be used as a part of an orientation before the clinical rotation or as an evaluation after the clinical rotation. To provide a realism, we recommend using standardized patients. And further research on the effects of using standardized patients is recommended.

Purpose: The purpose of this study was to evaluate the effect of extended CT field of view (FOV) on PET/CT of Standardized uptake value (SUV) when imaging extends beyond the CT FOV. Materials and Methods: CT images were reconstructed at different FOV sizes (500 and 700 mm). Two sets of CT images were reconstructed from the CT projection data by using two FOV sizes. Twenty patients were used in this study. PET images were reconstructed using attenuation maps with 500 mm CT FOV and 700 mm extended CT FOV images. Region of interests (ROIs) drawn on the PET images. In addition, twenty patients' PET images reconstructed by 500 mm CT FOV and 700 mm extended CT FOV were compared with $SUV_{max}$. Results: When using attenuation maps with 700 mm extended CT FOV, the $SUV_{max}$ analysis of liver (p=0.000), lung (p=0.007), mediastinum (p=0.001) were statistically significant. Conclusions: 700 mm extended CT FOV helps to recover the true activity distribution in the PET emission data. In addition, 700 mm extended CT FOV has affected SUV measurement of liver, lung, mediastinum.
