BACKGROUND: We evaluated the accuracy of the B. Braun Omnitest 5 blood glucose monitoring system (BGMS; Infopia Co. Ltd., Korea), which was recently developed for self-monitoring of blood glucose. METHODS: Precision was assessed according to Clinical and Laboratory Standards Institute guideline EP5-A3 with control materials containing low, normal, and high levels of glucose. Linearity was evaluated over the range of 52.5–548.0 mg/dL prepared from patient samples. For system accuracy, 100 capillary blood samples measured by the B. Braun Omnitest 5 BGMS were compared to plasma-equivalent blood glucose values of the fingertip blood samples measured by the YSI 2300 STAT PLUS glucose analyser (YSI Life Sciences, USA). Accuracy was evaluated according to the International Organization for Standardization (ISO) 15197: 2013 criteria. RESULTS: The range for the total coefficient of variation (%) was 1.5%–4.9% for three lots of strips. Both within-run precision and within-laboratory precision fulfilled the manufacturer's claim. ISO 15197: 2013 states that more than 95% of blood glucose measurement values must be within ±15 mg/dL for ranges below 100 mg/dL and ±15% for ranges above 100 mg/dL. Each of B. Braun Omnitest 5 lots satisfied ISO 15197: 2013, as 98.5% (197/200), 97.0% (194/200), and 99.5% (199/200) of values were within range. In consensus error grid analysis, respectively, 99.5%, 99.0%, and 100.0% of measurement values of each lot were within zone A, indicating that an average of over 99.0% of values were within zone A. CONCLUSIONS: B. Braun Omnitest 5 provided reliable results and satisfied the ISO 15197: 2013 accuracy criteria. This test is an appropriate BGMS for the self-monitoring of blood glucose.

Purpose: This study aimed to explore young adult donors’ experiences of living donor liver transplantation. Methods: A phenomenological research method was used. The participants were two women and six men. Data were collected through individual in-depth interviews from November 25th, 2019 to June 10th, 2020 and analyzed using Colaizzi’s phenomenological method. Results: Five theme clusters extracted from the young adult donors’ experiences were painful decision of a liver donation, the agony of both mind and body that overpowers youth, the bitter and bare face of reality that a young donor encounters, feeling the power of love that fills up the space of the organ removed, and liver donation becoming priming water for maturity. Conclusion The results of this study provide a deeper understanding of the lives of young adult donors who have experienced unexpected difficulties as well as self growth from the donation. It is expected that the results can be of use for developing and applying customized nursing interventions for management before and after liver donation among young adult donors.

Purpose: The purpose of the study was to understand the lived experience of illness among older females with cancer in South Korea. Methods: Data were collected from May to December of 2019 through individual in-depth interviews with eight older females with cancer who have undergone thorough cancer diagnosis and treatments. Transcribed data were analyzed using the hermeneutic phenomenological method developed by van Manen. Results: Six essential themes emerged: old body physically devastated through the fight against cancer; tug of war for symbiosis between cancer and the old body; home that does not provide comfort anymore; twilight years with no regrets even with cancer; womanhood to keep for a lifetime even in old age; and putting pieces together of the relationships around oneself. Conclusion Based on the participants’ illness experience, efforts need to be made to develop and implement effective strategies to improve nurses’ understanding of the life experiences of illness among older females with cancer in the Korean socio-cultural context, and to provide patient and family-centered nursing interventions that reflect patients’ age and gender characteristics.

Purpose: The purpose of this study was to analyze and clarify the concept of ‘optimistic bias.’ Methods: A review of the literature was conducted using several databases. The databases were searched using the following keywords: optimistic bias, optimism bias, and concept analysis. The literature on optimistic bias was reviewed using the framework of Walker and Avant’s conceptual analysis process. Results: Optimistic bias can be defined by the following attributes: 1) underestimation of personal risk, 2) vague confidence, 3) positive future prediction and 4) lack of risk recognition. The antecedents of optimistic bias are as follows: 1) risk perception, 2) self-efficacy, and 3) risk controllability. The consequences of optimistic bias are as follows: 1) reduced anxiety, 2) providing emotional stability, 3) negative consequences for preventive health behavior, 4) lack of attention to risk-related information, and 5) negative consequences for self-protection behavior. Conclusion The definition and attributes of optimistic bias identified by this study can provide a common understanding of this concept and help to develop a nursing intervention program effective in preventing, protecting, and improving health of subjects in the field of nursing practice.

Cancer is a disease which has the huge burden in worldwide, and cancer is the number one cause of death in Korea. At this point, the new framework for cancer monitoring index is required for regional cancer monitoring. Especially, cancer survivors are the important target which is rapidly increasing recently, also cancer survivor’s quality of care should be considered in the cancer monitoring index framework. To develop the Multidimensional Cancer Monitoring Index considering cancer survivor’s quality of care, we took into account cancer continuum which including prevention, detection, diagnosis, treatment, survivorship, assessment of quality of care and monitoring cancer patient, and end-of life care for stage. For target, components of health care delivery system such as patient, family, provider, payer, and policy maker are included. Also, Donabedian model which is a framework for examining health services and evaluating quality of health care such as structure, process, and outcome is applied to contents. This new cancer monitoring framework which includes multidimensional components could help to develop regional cancer monitoring index, and to make national cancer management and prevention policy in the future.

Background: Cervical cancer is the fourth common cancer in women worldwide. The Papanicolau test is the primary screening procedure to detect abnormal cervical cells.Colposcopy is the main procedure for discriminating high-grade cervical lesions. The study aimed at clarifying the discrepancy between cervical cytology and colposcopic biopsy histology as well as confounding factors. Methods: Eligible patients visited thirteen tertiary hospitals for colposcopic biopsy following cervical cytology and human papillomavirus (HPV) genotypes between January and December 2018. Baseline characteristics including age, body mass index (BMI), and parity were collected. Results: In our study, 3,798 eligible patients were included. Mean age of patients was 42.7(19–88) years and mean BMI was 22.5 (16.9–34.1) kg/m2 . The referred cervical cytologic findings consisted of 495 normal, 1,390 atypical squamous cells of undetermined significance, 380 atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion, 792 low-grade squamous intraepithelial lesion, 593 high-grade squamous intraepithelial lesion, 79 atypical glandular cells, 46 squamous cell carcinoma, and 23 adenocarcinoma. HPV-positive findings were found in 3,008 (79.2%) patients and were not detected in 914 (24.1%) cases. The risk of unexpected low-grade lesions from histology was higher in patients > 45 years (odds ratio [OR], 2.137; 95% confidence intervals [CIs], 1.475–3.096). In contrast, the risk of unexpected high-grade lesions from colposcopic biopsy was lower in patients ≥ 45 years (OR, 0.530; 95% CI, 0.367–0.747) and HPV 16/18 infection was higher than other HPV (OR, 1.848; 95% CI, 1.385–2.469). Conclusion Age and HPV genotypes were responsible for the discrepancies between cytology and histology. Precautions should be taken for women over the age of 45 in triage for colposcopy in order to avoid unnecessary testing.

Despite remarkable progress in understanding and treating gastrointestinal stromal tumors (GISTs) during the past two decades, the pathological characteristics of GISTs have not been made clear yet. Furthermore, concrete diagnostic criteria of malignant GISTs are still uncertain. We collected pathology reports of 1,227 GISTs from 38 hospitals in Korea between 2003 and 2004 and evaluated the efficacy of the NIH and AFIP classification schemes as well as the prognostic factors among pathologic findings. The incidence of GISTs in Korea is about 1.6 to 2.2 patients per 100,000. Extra-gastrointestinal GISTs (10.1%) are more common in Korea than in Western countries. In univariate analysis, gender, age, tumor location, size, mitosis, tumor necrosis, vascular and mucosal invasions, histologic type, CD34 and s-100 protein expression, and classifications by the NIH and AFIP criteria were found to be significantly correlated with patient's survival. However, the primary tumor location, stage and classification of the AFIP criteria were prognostically significant in predicting patient's survival in multivariate analysis. The GIST classification based on original tumor location, size, and mitosis is more efficient than the NIH criteria in predicting patient's survival, but the mechanism still needs to be clarified through future studies.
