This study was conducted by collecting data from September to November 2021 for third-year students enrolled in the Department of Nursing at a university located in D city in order to confirm the educational effect of psychiatric nursing simulation practice using standardized patients. For data analysis, using the SPSS/WIN 22.0 program, the results before and after the simulation class on general characteristics, communication ability, problem-solving ability, learning self-efficacy, and learning satisfaction were compared and verified. As a result of the study, communication ability (t=-3.199, p=.004) and learning satisfaction (t=-3.342, p=.003) significantly increased after education. However, problem-solving ability (t=-1.875, p=.072) and learning self-efficacy (t=-1.432, p=.164) were not statistically significant. Therefore, it is necessary to continuously operate education applying standardized patients to improve the communication ability and learning satisfaction of nursing students.

The intervertebral disc is a crucial structure located between each vertebral body, except C1 and C2 and the fused sacral vertebrae, which provides cushioning and stability. However, sometimes these discs may bulge or extrude, causing painful conditions and various neurological problems such as ataxia, paresis, motor or sensorimotor paralysis. As a result, dogs affected by intervertebral disc disease (IVDD) can suffer a significant decrease in their quality of life. The main objective of this study was to provide comprehensive data on the body size of several IVDD-susceptible dog breeds commonly bred in South Korea, which could help develop supportive devices for IVDD patients. Using standardized measurements, the study aimed to design appropriate support tools, taking into account the mobility challenges faced by IVDD patients. The findings provide valuable data to improve the quality of life of patients with IVDD. In addition, it may lay the foundation for research to establish the correlation between body size and IVDD through future research.

Objective : This study aimed to determine the incidence and analyze trends of the herniated lumbar disc (HLD) based on a national database in the Republic of Korea (ROK) from January 2008 to December 2016. Methods : This study was a retrospective analysis of data obtained from the national health-claim database provided by the National Health Insurance Service for 2008-2016 using the International Classification of Diseases. The crude incidence and age-standardized incidence of HLD were calculated, and additional analysis was conducted according to age and sex. Changes in trends in treatment methods and some treatments were analyzed using the Korean Classification of Diseases procedure codes. Results : The number of patients diagnosed with HLD was 472245 in 2008 and increased to 537577 in 2012; however, it decreased to 478697 in 2016. The pattern of crude incidence and the standardized incidence were also similar. Overall, the incidence of HLD increased annually for the 30s, 40s, 50s, and 70s until 2012 and then decreased. However, the incidence of HLD for the 80s continued to increase. The crude incidence of HLD in female patients exceeded that of male patients in their middle age (30s or 40s) and was 1.5-1.6 times higher than in male patients in their 60s. The total number of open discectomy (OD) increased from 71598 in 2008 to 93942 in 2012 and then decreased to 85846 in 2016. The rate of younger patients (the 20s, 30s, and 40s) who underwent OD was decreased, and the rate of younger patients who underwent percutaneous endoscopic lumbar discectomy was increased. However, the rate of older patients (the 70s and 80s) who underwent OD was continuously increased. Conclusion : This nationwide data on HLD from 2008 to 2016 in the ROK demonstrated that the crude incidence and the standardized incidence increased until 2012 and then decreased. The annual crude incidence was different according to age and sex. These findings may be considered when deciding future health policy, especially in countries with a similar national health insurance system (or with plans to adopt).

Background/Aims To evaluate the efficacy and safety of Aloe vera (AV) in patients with irritable bowel syndrome (IBS). Methods We searched the MEDLINE, EMBASE, and Cochrane databases for studies dated between 1st January 1960 and 30th December 2017. Eligible randomized controlled trials (RCTs) compared AV to placebo in patients with IBS. The primary outcome was standardized mean difference of the change in severity of IBS symptoms as measured by patient-rated scales. Secondary outcomes included response rate of IBS symptoms and adverse events. Heterogeneity among studies was assessed using Cochrane's Q and $I^2$ statistics. Results Three RCTs with a total of 151 patients with IBS were included. The meta-analysis showed a significant difference for patients with AV compared to those with placebo regarding improvement in IBS symptom score (standardized mean difference, 0.41; 95% CI, 0.07-0.75; P = 0.020). Using intention-to-treat analysis, the AV patients showed significantly better response rates of IBS symptoms compared to placebo (pooled risk ratio, 1.69; 95% CI, 1.05-2.73; P = 0.030). No adverse events related with AV were found in included studies. There was no significant heterogeneity of effects across studies (P = 0.900; $I^2=0%$). Conclusion AV is effective and safe for the treatment of patients with IBS compared to placebo.

Objective: We aimed to evaluate the diagnostic value and prognostic relevance of FDG positron emission tomography/computed tomography (PET-CT) in extrahepatic cholangiocarcinoma patients. Materials and Methods: This study included 234 extrahepatic cholangiocarcinoma patients who underwent FDG PET-CT between June 2008 and February 2016. The diagnostic performance of FDG PEG-CT was compared to that of contrast-enhanced multidetector row CT (MDCT) and MRI. Independent prognosticators for poor survival were also assessed. Results: The sensitivity of FDG PET-CT for detecting primary tumor and regional lymph node metastases was lower than that of MDCT or MRI (p < 0.001), whereas the specificity and positive predictive value for detecting regional lymph nodes metastases was significantly better in FDG PET-CT compared to MDCT and MRI (all p < 0.001). There was no significant difference in the diagnostic yield of distant metastases detection among three diagnostic imaging techniques. In a multivariate analysis, maximum standardized uptake values (SUV_max) of the primary tumor (adjusted hazard ratio [HR], 1.75; 95% confidence interval [CI], 1.13-2.69) and of the metastatic lesions ≥ 5 (adjusted HR, 8.10; 95% CI, 1.96-33.5) were independent contributors to poor overall survival in extrahepatic cholangiocarcinoma patients. In a subgroup analysis of 187 patients with periductal infiltrating type of cholangiocarcinoma, an SUV_max of the primary tumor ≥ 5 was associated with an increased risk of regional lymph node (adjusted odds ratio [OR], 1.60; 95% CI, 0.55-4.63) and distant metastases (adjusted OR, 100.57; 95% CI, 3.94-2567.43) at diagnosis as well as with poor overall survival (adjusted HR, 1.81; 95% CI, 1.04-3.15). Conclusion: FDG PET-CT showed lower sensitivity for detecting primary tumor and regional lymph node involvement than MDCT and MRI. However, the SUV_max of primary tumors and metastatic lesions derived from FDG PET-CT could have significant implications for predicting prognoses in extrahepatic cholangiocarcinoma patients.

Purpose : Standardized pillow may not support patient's individual cervical spine thoroughly when head and neck radiation therapy with $Tomotherapy^{(R)}$. Therefore, the purpose of this study was to make a comparative analysis for the difference of using standardized pillow only and using customized cervical spine immobilizer with standardized pillow. Materials and Methos : The head and neck cancer patients who are treated image-guided radiation therapy(IGRT) with $Tomotherapy^{(R)}$ were divided into two groups, 20 patients using standardized pillow only, and 20 patients using customized cervical spine immobilizer with standardized pillow. We achieved 20 mega-voltage computed tomography(MVCT) image per patient, compared curvature of the cervical spine in MVCT with curvature of the cervical spine in CT-simulation. Results : Results of comparative analysis were curvature consistency 95.9 %, maximum error of distance 41.9 mm, average distance error per fractionation 19.4 mm, average standard deviation 1.34 mm in case of using standardized pillow only, curvature consistency 98.9 %, maximum error of distance 12.9 mm, average distance error per fractionation 5.8 mm, average standard deviation 0.59 mm in case of using customized cervical spine immobilizer with standardized pillow. Conclusion : Using customized cervical spine immobilizer shows higher reproducibility and low distance error, therefore customized cervical spine immobilizer could be useful for head and neck cancer patients who need radiation therapy.

Training for asthma patients by professionals has been highly emphasized for patients' self-management. In the present study, three standardized training sessions targeting hospital pharmacists were performed. On the basis of the number of training sessions taken, a non-educated group (CG), an once-educated group (NG), and a twice more-educated group (IG) were allocated. The most frequent errors of using an inhalant were shaking before the use in MDI while taking breathe out before inhaling in the case of DPI, and the total average number of errors were the biggest for CG and the smallest in IG. On comparison in the number of the four symptoms of asthma according to the level of seriousness, it was revealed that the total average number was the biggest in CG and the smallest in IG. In the level of awareness regarding the contents of training for patients, patients over 50 tended to answer that they were aware of education contents, and particularly in mouth rinsing and the use before/after a meal, significant similarity was examined. Regular asthma patient training performed by hospital pharmacists appeared to reduce errors in the inhaler usage, increase the quality of life of an patient, and help a patient remember the contents of the training. Especially among patients over 50, it was found to be more effective and retraining of more than two sessions was requisite.

Purpose: Different esophagojejunostomy (EJ) reconstruction methods are used after totally laparoscopic total gastrectomy (TLTG), and none is considered a standard technique. This report describes a 2-layer hand-sewn EJ technique during TLTG; we also evaluated postoperative morbidity associated with this technique. Materials and Methods: This retrospective cohort study included all consecutive patients who underwent TLTG for gastric cancer (GC) from 2012 to 2016 at 2 affiliated teaching hospitals. All participating surgeons performed standardized intracorporeal 2-layer hand-sewn EJ. Results: We included 51 patients who underwent TLTG for GC and standardized EJ anastomosis. Twenty-seven (53%) were male, and the median age was 60 (36-87) years. The average operative time was $337{\pm}71minutes$ and intraoperative bleeding was $160{\pm}107mL$. There were no open conversions related to EJ. Postoperative morbidity was observed in 9 (17.0%) patients. There was no postoperative mortality. EJ leakage was observed in 2 patients (3.8%) and 1 patient (1.9%) developed EJ stenosis. Patients with leakage were managed non-operatively and the patient with stenosis required endoscopic dilation. The median length of hospital stay was 8 (6-29) days. Conclusions: Two-layer hand-sewn EJ during TLTG for GC is a feasible and safe technique. This method avoids a laparotomy for reconstruction and the disadvantages associated with laparoscopic introduction of mechanical staplers for EJ, and provides an alternative for alimentary tract reconstruction after TLTG.
