PURPOSE: Internal mammary lymph node (IMN) involvement is associated with poor prognosis in breast cancer. This study investigated the treatment outcomes of initial clinically IMN-positive breast cancer patients who received adjuvant radiotherapy (RT), including IMN irradiation, following primary breast surgery. MATERIALS AND METHODS: We retrospectively reviewed data of 95 breast cancer patients with clinically detected IMNs at diagnosis treated with surgery and RT between June 2009 and December 2015. Patients received adjuvant RT to the whole breast/chest wall and regional lymph node (axillary, internal mammary, and supraclavicular) areas. Twelve patients received an additional boost to the IMN area. RESULTS: The median follow-up was 43.2 months (range, 4.5 to 100.5 months). Among 77 patients who received neoadjuvant chemotherapy, 52 (67.5%) showed IMN normalization and 19 (24.6%) showed a partial response to IMN. There were 3 and 24 cases of IMN failure and any recurrence, respectively. The 5-year IMN failure-free survival, disease-free survival (DFS), and overall survival (OS) were 96%, 70%, and 84%, respectively. IMN failure-free survival was significantly affected by resection margin status (97.7% if negative, 87.5% for close or positive margins; p = 0.009). All three patients with IMN failure had initial IMN size ≥1 cm and did not receive IMN boost irradiation. The median age of the three patients was 31 years, and all had hormone receptor-negative tumors. CONCLUSION: RT provides excellent IMN control without the support of IMN surgery. Intensity-modulated radiotherapy, including IMN boost for breast cancer patients, is a safe and effective technique for regional lymph node irradiation.

PURPOSE: IBTR! 2.0 nomogram is web-based nomogram that predicts ipsilateral breast tumor recurrence (IBTR). We aimed to validate the IBTR! 2.0 using an external data set. MATERIALS AND METHODS: The cohort consisted of 2,206 patients, who received breast conserving surgery and radiation therapy from 1992 to 2012 at our institution, where wide surgical excision is been routinely performed. Discrimination and calibration were used for assessing model performance. Patients with predicted 10-year IBTR risk based on an IBTR! 2.0 nomogram score of <3%, 3%–5%, 5%–10%, and >10% were assigned to groups 1, 2, 3, and 4, respectively. We also plotted calibration values to observe the actual IBTR rate against the nomogram-derived 10-year IBTR probabilities. RESULTS: The median follow-up period was 73 months (range, 6 to 277 months). The area under the receiver operating characteristic curve was 0.607, showing poor accordance between the estimated and observed recurrence rate. Calibration plot confirmed that the IBTR! 2.0 nomogram predicted the 10-year IBTR risk higher than the observed IBTR rates in all groups. High discrepancies between nomogram IBTR predictions and observed IBTR rates were observed in overall risk groups. Compared with the original development dataset, our patients had fewer high grade tumors, less margin positivity, and less lymphovascular invasion, and more use of modern systemic therapies. CONCLUSIONS: IBTR! 2.0 nomogram seems to have the moderate discriminative ability with a tendency to over-estimating risk rate. Continued efforts are needed to ensure external applicability of published nomograms by validating the program using an external patient population.

PURPOSE: The purpose of this study was to compare communication competence, nursing professionalism, work environment and job satisfaction between outpatient nurses and ward nurses, and to identify the correlation among variables.METHODS: The participants were 90 outpatient nurses and 98 ward nurses at the two general hospitals. Data were collected using self-administered questionnaires. Data were analyzed using descriptive statistics, χ2-test, independent t-test and Pearson's correlation coefficient.RESULTS: There were statistically significant differences between two groups in nursing professionalism, possibilities for development, commitment to the workplace, social support from colleagues, social community at work and job satisfaction, outpatient nurses showed higher level than ward nurses except commitment to the workplace. The work environment variables and nurses' job satisfaction were mostly correlated. Job satisfaction showed significant negatively correlated with quantitative demands, emotional demands and role conflicts in both groups nurses.CONCLUSION: These findings showed that nursing work environments were the most important factor for job satisfaction of both group nurses. Therefore, it is necessary to put efforts in improving nursing work environment and to develop diverse strategies for human resource management.

The purpose of this study was to focus on the number of brushing strokes among the performance factors and identify if the 10 times stroke of the rolling method is rational. Moreover, we evaluated the changes in oral health knowledge, perception, and behavior after our rolling method instruction. The 10-stroke method of toothbrushing has been regarded as an effective method of removal of dental plaque, although there is little evidence to support this claim. We allocated 40 healthy subjects to two intervention groups. During five visits, we measured a score for dental plaque removal and instructed the subjects on a toothbrushing technique with 5 or 10 strokes per section. At the initial and final visits, subjects completed a questionnaire on one designed specifically for this study about oral health knowledge, perceptions, and behaviors. Repeated measures analysis of variance was used to compare the dental plaque removal score between the groups, and the changes in scores within each group over time. We also compared changes in mean scores in oral health knowledge, perceptions and behaviors before and after toothbrushing instruction. We found that the score for dental plaque removal increased with each additional toothbrushing instruction in both groups (p < 0.001). However, we found no differences in the dental plaque removal scores between the 5-stroke and 10-stroke groups (p=0.399). The levels of oral health knowledge, perceptions and behaviors increased after the toothbrushing instructions in both groups. Our findings suggest that there is no advantage in emphasizing the 10-stroke method of toothbrushing in an oral health education program.

Capsule endoscopy (CE) enables evaluation of the entire mucosal surface of the small bowel (SB), which is one of the most important steps for evaluating obscure gastrointestinal bleeding. Although the diagnostic yield of SB CE depends on many clinical factors, there are no reports on quality indicators. Thus, the Korean Gut Image Study Group (KGISG) publishes an article titled, “Quality Indicators for Small Bowel Capsule Endoscopy” under approval from the Korean Society of Gastrointestinal Endoscopy (KSGE). Herein, we initially identified process quality indicators, while the structural and outcome indicators are reserved until sufficient clinical data are accumulated. We believe that outcomes of SB CE can be improved by trying to meet our proposed quality indicators.

The aim of this study was to analyze in depth the standardized Clinical dental hygiene curriculum of the Fones School in the United States. We investigated the clinical dental hygiene curriculum in 2015~2016 including title, credit, hours, contents, goals, competencies, and evaluation. We obtained the course syllabus and data related to each subject, for each grade, from the professors and students at the university. The goals and competencies, of the clinical dental hygiene program, which were based on the goals of the Fones School and the mission of the University of Bridgeport, were developed in accordance with the dental hygienist practice standards proposed by the American Dental Hygienists Association. The curriculum consisted of theory to teach proper dental hygiene care procedures and incorporated practical exercises that modeled an actual clinical setting. The students had to document the procedures performed for each client/patient and improve their clinical competency through discussion with the professors. Dental hygiene care should be provided for children, adolescents, adults, elderly, and patients, which includes patients with moderate or severe periodontal status. Students were evaluated by a paper test or case study presentation and their clinical evaluation was based on their clinical competency. In particular, professors evaluated students on a rotational basis, so they could evaluate the level of achievement of clinical competency of all students and find ways to improve any weaknesses. Therefore, the current study suggested that clinical dental hygiene program in Korea could be improved if based on the curriculum of Fones School in the United States.

The purpose of this study was to provide basic data to standardize the clinical dental hygiene curriculum, based on analysis of current clinical dental hygiene curricula in Korea. We emailed questionnaires to 12 schools to investigate clinical dental hygiene curricula, from February to March, 2017. We analyzed the clinical dental hygiene curricula in 5 schools with a 3-year program and in 7 schools with a 4-year program. The questionnaire comprised nine items on topics relating to clinical dental hygiene, and four items relating to the dental hygiene process and oral prophylaxis. The questionnaire included details regarding the subject name, the grade/semester/credit system, course content and class hours, the number of senior professors, and the number of patients available for dental hygiene clinical training purposes. In total, there were 96 topics listed in the curricula relating to clinical dental hygiene training, and topics varied between the schools. There was an average of 20.4 topic credits, and more credits and hours were allocated to the 4-year program than to the 3-year program. On average, the ratio of students to professors was 21.4:1. Course content included infection control, concepts for dental hygiene processes, dental hygiene assessment, intervention and evaluation, case studies, and periodontal instrumentation. An average of 2 hours per patient was spent on dental hygiene practice, with an average of 1.9 visits. On average, student clinical training involved 19 patients and 26.6 patients in the 3-year and 4-year programs, respectively. The average participation time per student per topic was 38.0 hours and 53.1 hours, in the 3-year and 4-year programs, respectively. Standardizing the clinical dental hygiene curricula in Korea will require consensus guidelines on topics, the number of classes required to achieve core competencies as a dental hygienist, and theory and practice time.

BACKGROUND: OneTouch Diabetes Management Software (OTDMS) is an efficient way to track and monitor the blood glucose level. It is possible to download data from the OneTouch Ultra via the meter's data port, and to transform the numbers of the blood glucose level into a graph, a chart, or statistics. The objectives of this study were to evaluate whether the use of OTDMS in consultation hours would improve patients' knowledge of diabetes mellitus (DM), compliance, satisfaction with doctor and medical treatment, doctor-patient reliability, and glucose control. METHODS: All patients were randomized into either the OTDMS group using OneTouch Ultra or the control groups not using it. Both groups had conventional DM education and only the OTDMS group used data from OTDMS as explanation materials during consultation hours. At enrollment and after 6 months, we performed a questionnaire survey consisting of the diabetes knowledge test, items for compliance of treatment, patient's satisfaction, doctor-patient reliability, and glycosylated hemoglobin (HbA1c). RESULTS: We analyzed 6-month follow-up data from 92 patients (OTDMS 42 vs. control 50). Both groups showed significant improvements in HbA1c, diabetes knowledge, compliance, reliability, and satisfaction after 6 months. However, there were no significant differences between OTDMS and control groups overall. Only "weekly frequency of checking blood glucose level" of compliance and "trying to follow doctor's order" of reliability showed better results in the OTDMS group. CONCLUSION: Using the OTDMS system for explanation during consultation hours seems to be more helpful to improve patient's compliance and reliability, especially for checking blood glucose level and trying to follow the doctor's order.

PURPOSE: Purpose of this study was to identify major trends of action research from 2006 to 2013 and suggest directions for activating and advancing domestic action research in nursing. METHODS: A review was made of 118 action research studies in hospital settings reported in international journals. Search from PubMed, Ovid, and CINHAL was done using analysis criteria developed by the researchers. General and methodological characteristics and focus on changing outcomes of action research were analyzed. RESULTS: The major group of researchers belonged to colleges/universities (40.7%). Methods included use of qualitative methods (61.0%), research questions (24.6%), and use of theoretical models (35.6%). Prevalent data collection methods were interviews (20.2%), and 48.3% showed more than a 1-cycle process including spiral circulation structure. Focus of changing outcomes of the 56 papers including more than 1-cycle were practice (66.1%), environment (8.9%), client-nurse (7.1%). CONCLUSION: Trends in action research in nursing were identified providing necessary reasons to increase action research in nursing as follows: needs of various researchers including stakeholders as well as healthcare providers, various research designs including unconstrained reflection and writing, specific presentation of adapted theoretical models and action strategies, and quality assurance for validity and reliability of research processes and outcomes.
