BACKGROUND: There is a recent trend of increased use of the gel test for the detection of unexpected antibodies (Abs) because of its simplicity and ease with which definitive interpretation can be made. However, because of the low insurance payments in Korea, only the LISS/Coombs card is used and thus the detection rate of the cold Abs has decreased. We have studied the detection rates of the Abs in patients by using the LISS/Coombs gel test and thus evaluated the clinical usefulness of the LISS/Coombs gel test. METHODS: Abs screening tests have been carried out using the DiaMed(TM) LISS/Coombs gel card test (Murten, Switzerland) on 14,942 patients for whom blood transfusions were ordered between July 1, 1997 and March 31, 2001. When the test for Abs was positive, Ab identification tests were further carried out with the DiaMed(TM) LISS/Coombs gel card and the ID-DiaPanel 1-11. RESULTS: Eighty-one out of 14,942 patients (0.54%) revealed positive results. Of these, 15 showed anti-E, 5 showed anti-E+c, 4 showed anti-C, 3 showed anti-D, 2 showed anti-Jk(a), 1 each showed anti-c, anti-M, anti-Lu(a), and anti-K Abs. CONCLUSIONS: Although the detection rate for the cold Abs of the LISS/Coombs gel test was low, it is considered to be highly useful because of the high detection rate for the clinically important warm Abs, the simplicity in carrying out the test, and the easy readability of test results.

OBJECTIVES: The present study aimed to evaluate the validity of a set of self-reported questionnaires for periodontitis for estimating the prevalence of chronic adult periodontitis in the Korean population. METHODS: The questionnaire is comprised of a total of 14 questions with four summarized concepts including self-diagnosis of oral status, subjective signs related to oral health, smoking and drinking status, and use of auxiliary oral hygiene devices including scaling. The predictiveness of the measures from these self-reported questions was assessed by logistic regression modeling using receiver operating characteristic (ROC) statistics, sensitivity, and specificity. RESULTS: The sensitivity, specificity, and AUC including all questions were 0.571, 0.768, and 0.781, respectively; the sum of sensitivity and specificity was 1.34. To gain robustness, a simplified predictive model was built with six questions. Its results were 0.536, 0.817, and 0.762 for sensitivity, specificity, and AUC, respectively. The sum of sensitivity and specificity was found to be 1.35. CONCLUSIONS: The self-reported questionnaire for periodontitis showed considerable validity, but further study is required to provide optimal validity and predictability.

OBJECTIVES: The aim of this study was to compare the tooth bleaching effect of two whitening materials in toothpaste i.e., hydroxyapatite and hydrogen peroxide on. In a randomized, double blinded controlled clinical trial, 85 participants with tooth colorations were assigned to use one of three toothpastes containing either hydroxyapatite (0.25%), hydrogen peroxide (0.75%), or no active ingredient (placebo). The patients were examined at baseline and 1, 2, and 3 months after usage. METHODS: The patients underwent an oral examination, tooth shade measurement, and a subjective evaluation. During the oral examination, the patient's oral health status was determined. ShadeEye NCC and Vita classical shade guide were used to determine the tooth color. Further, the patients were asked to assess the color of their own teeth using a visual analog scale (VAS) scale (range, 1-5). RESULTS: According to the CIELAB system, a significantly greater color change (Deltab*) was observed in the hydrogen peroxide group (2.10+/-1.54) than in the hydroxyapatite (1.50+/-1.09) and control (0.94+/-0.75) groups after 3 months of toothpaste usage (P<0.002). The DeltaE*color change was not statistically significant among the 3 groups at each time point (P>0.05). The subjective evaluation results of the hydroxyapatite (P=0.023) and hydrogen peroxide (P=0.047) groups were statistically significant at each time point. CONCLUSIONS: The hydrogen peroxide-containing toothpaste caused significant lightening of tooth coloration than the hydroxyapatite and placebo toothpastes.

OBJECTIVES: The aim of this study is to identify factors determining the purchase of private health insurance under the mandatory National Health Insurance(NHI) system in Korea. METHODS: The data were collected by the National Cancer Center in Korea. It includes cancer patients who were newly diagnosed with stomach (ICD code, C16), lung(C33-C34), liver (C22), colorectal cancer(C18-C20) or breast(C50) cancer. Data were gathered from the hospital Order Communication System (OCS), medical records, and face-to-face interviews, using a structured questionnaire. Clinical, socio-demographic and private health insurance related factors were also gathered. RESULTS: Overall, 43.9% of patients had purchased one or more private health insurance schemes related to cancer, with an average monthly premium of won 65,311 and an average benefit amount of won 19 million. Females, younger aged, high income earners, national health insurers and metropolitan citizens were more likely to purchase private health insurance than their counterparts. CONCLUSIONS: About half of Korean people have supplementary private health insurance and their benefits are sufficient to cover the out-of-pocket fees required for cancer treatment, but inequality remains in the purchase of private health insurance. Further studies are needed to investigate the impacts of private health insurance on NHI, and the relationship between cancer patients' burden and benefits.

Purpose: The aim of this study was to develop a simulation-based High Flow Nasal Cannula Oxygen Therapy training program based on NLN/ISF to identify the effect on knowledge, clinical performance, and educational satisfaction compared to a group who had traditional High Flow Nasal Cannula Oxygen Therapy training after applying it to clinical nurses. Methods: 31 experimental groups and 33 control groups were conducted from August 2019 to September 2019 for inexperienced nurses over 4 months to 5 years with no experience using high-flow oxygen therapy. Educational programs were developed in scenarios according to Airvo2 and Optiflow, such as facilitator, participant, educational condition, design, characteristics, and educational outcomes. The education application was conducted in advanced for knowledge and clinical performance ability after watching therapy video. Since then, a total of 90 minutes have been conducted for respiratory failure theory training, airvo2 and optiflow simulation training, and debriefing. After applying the education, the medical institution measured nurses’ knowledge, clinical performance, and education satisfaction. Data were analyzed using descriptive statistics, with the SPSS/WIN 22.0 program. Results: Both knowledge and educational satisfaction were higher in the experimental group than in the control group (t=-14.09, p<.001), (t=-12.99, p<.001). The clinical performance for both use of Optiflow and Airvo2 were higher in the experimental group than in the control group (t=-11.39, p<.001), (t=-11.38, p<.001) . Conclusion Results showed that the simulation-based High Flow Nasal Cannula Oxygen Therapy training was effective with the experimental group having increased scores for every area of this study.
