Osteoporosis and osteoporotic fractures cause socioeconomic concerns, and medical system and policies appear insufficient to prepare for these issues in Korea, where the older adult population is rapidly increasing. Many countries around the world are already responding to osteoporosis and osteoporotic fractures by adopting fracture liaison service (FLS), and such an attempt has only begun in Korea. In this article, we introduce the operation methods for institutions implementing FLS and characteristics of services, and activities of the FLS Committee for FLS implementation in the Korean Society for Bone and Mineral Research. In addition, we hope that the current position statement will contribute to the implementation of FLS in Korea and impel policy changes to enable a multidisciplinary and integrated FLS operated under the medical system.

Purpose: The introduction of immune checkpoint inhibitors represents a major advance in the treatment of lung cancer, allowing sustained recovery in a significant proportion of patients. Nivolumab is a monoclonal anti–programmed death cell protein 1 antibody licensed for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) after prior chemotherapy. In this study, we describe the demographic and clinical outcomes of patients with advanced NSCLC treated with nivolumab in the Korean expanded access program. Materials and Methods: Previously treated patients with advanced non-squamous and squamous NSCLC patients received nivolumab at 3 mg/kg every 2 weeks up to 36 months. Efficacy data including investigator-assessed tumor response, progression data, survival, and safety data were collected. Results: Two hundred ninety-nine patients were treated across 36 Korean centers. The objective response rate and disease control rate were 18% and 49%, respectively; the median progression-free survival was 2.1 months (95% confidence interval [CI], 1.87 to 3.45), and the overall survival (OS) was 13.2 months (95% CI, 10.6 to 18.9). Patients with smoking history and patients who experienced immune-related adverse events showed a prolonged OS. Cox regression analysis identified smoking history, presence of immune-related adverse events as positive factors associated with OS, while liver metastasis was a negative factor associated with OS. The safety profile was generally comparable to previously reported data. Conclusion This real-world analysis supports the use of nivolumab for pretreated NSCLC patients, including those with an older age.

A resolution adopted by the World Health Assembly in 2014 stated that all nurses should be equipped with palliative care skills in order to integrate palliative care into a day-to-day healthcare system. This article introduces the palliative nursing competency that was developed for the Korean environment by the Korean Hospice Palliative Nursing Research Network based on its study of overseas cases where this competency and competency-based training were developed. This is the first step towards the development of competency-based palliative nursing education, and active efforts should be made to integrate this competency into the undergraduate nursing curriculum.

Neuroinflammation is an immune response within the central nervous system against various proinflammatory stimuli. Abnormal activation of this response contributes to neurodegenerative diseases such as Parkinson disease, Alzheimer’s disease, and Huntington disease. Therefore, pharmacologic modulation of abnormal neuroinflammation is thought to be a promising approach to amelioration of neurodegenerative diseases. In this study, we evaluated the synthetic flavone derivative 3′,4′-dihydroxyflavone, investigating its anti-neuroinflammatory activity in BV2 microglial cells and in a mouse model. In BV2 microglial cells, 3′,4′-dihydroxyflavone successfully inhibited production of chemokines such as nitric oxide and prostaglandin E2 and proinflammatory cytokines such as tumor necrosis factor alpha, interleukin 1 beta, and interleukin 6 in BV2 microglia. It also inhibited phosphorylation of mitogen-activated protein kinase (MAPK) and nuclear factor (NF)-κB activation. This indicates that the anti-inflammatory activities of 3′,4′-dihydroxyflavone might be related to suppression of the proinflammatory MAPK and NF-κB signaling pathways. Similar anti-neuroinflammatory activities of the compound were observed in the mouse model. These findings suggest that 3′,4′-dihydroxyflavone is a potential drug candidate for the treatment of microglia-related neuroinflammatory diseases.

BACKGROUND: It is a very important social issue for Korea to have a healthy old age as an aged society. Aging causes a lot of physical changes, especially sarcopenia. Sarcopenia is defined as a persistent decrease in skeletal muscle and muscle strength. Sarcopenic obesity is a phenomenon in which fat is replaced instead of muscle. The purpose of this study was to examine the prevalence of sarcopenia and sarcopenic obesity in Korean elderly and to analyze the relationship with chronic disease. METHODS: Data from the 2008 to 2011 the Korea National Health and Nutrition Survey were used. A total of 3,492 patients were classified into 3 groups (non-sarcopenia, sarcopenia, sarcopenic obesity), and general, anthropometry, health behavior, nutrient intake and chronic disease status were compared by the statistical analysis. RESULTS: The rate of moderate exercise was significantly lower in the sarcopenia and sarcopenic-obesity group than in the non-sarcopenia group (P=0.007). The sarcopenic obesity group had significantly higher energy (P=0.005), protein (P=0.046) and fat (P=0.001) intake than the sarcopenic group. The sarcopenic-obesity group had the highest ratio of diabetes (P=0.023) and dyslipidemia (P=0.004) in the 3 groups. Compared with the non-sarcopenia group, in the sarcopenia and sarcopenic obesity groups, the odds ratios (ORs) of diabetes was increased by 1.24 and 2.16 while the ORs of dyslipidemia was increased by 1.12 and 1.50, respectively. CONCLUSIONS: Regular exercise and adequate nutrient intake (energy, protein and fat) are essential for the prevention of sarcopenia in Korean elderly, and management of chronic disease in sarcopenic obesity elderly is important.

PURPOSE: This study was to examine the effects of a footbath program on heart rate variability, blood pressure, body temperature and fatigue of stroke patients with stroke-induced hemiparesis. METHODS: A non-equivalent control group pretest-posttest design was used. Participants were 40 stroke patients, twenty for the footbath program and twenty for the control group, who were hospitalized in a long-term rehabilitation hospital in G city of Korea, from February to April 2014. The twenty participants in the experimental group received the intervention of footbaths and an educational program focused on the prevention of stroke complications; Collected data were analyzed by the IBM SPSS WIN 20.0 program using a t-test, chi2 test, Mann-Whitney U test and repeated measures ANOVA. RESULTS: Significant differences were found in heart rate variability, systolic blood pressure, hand and foot temperatures and fatigue between the two groups. But no significant differences were found in diastolic blood pressure, core temperatures, forehead temperatures, and hand temperatures between the two groups. CONCLUSION: The footbath program was an effective intervention for skin temperature change and fatigue reduction for stroke patients. Therefore, it is recommended that the footbath program can be utilized as an effective nursing intervention for stroke patients in long-term rehabilitation care hospitals.

PURPOSE: The purpose of this study was to examine the effects of workplace spirituality and organizational citizenship behavior on nurses' performance of nursing. METHODS: This study was done over a 6 month period, with 395 nurses participants from 5 different general hospitals with 400 beds in 4 regions of Korea. Data were gathered using self-reported questionnaires from July 23 to August 21, 2015. Data were analyzed using descriptive statistics, independent t-test, one way ANOVA, Pearson correlation coefficients, and multiple regression analyses with IBM SPSS 21.0 program. RESULTS: Nursing performance showed positive correlations with workplace spirituality and organizational citizenship behavior. The significant predictors of the nursing performance by nurses were a master's degree or higher (β=.26), civic virtue (β=.19), courtesy (β=.12), 40 years of age or older (β=.09), a sense of empathy (β=.07), and a bachelor's degree in nursing (β=.06). These variables explained 39.2% of the variance in nursing performance by nurses. CONCLUSION: Based on the outcomes of this study, there is a need to develop intervention programs that can inspire nurse to show spontaneous organizational citizenship behavior, and enhance their workplace spirituality. Related variables including academic credentials should also be taken into account.

PURPOSE: High-affinity receptor I (FcεRI) on mast cells and basophils plays a key role in the immunoglobulin E (IgE)-mediated type I hypersensitivity mediated by allergen cross-linking of the specific IgE-FcεRI complex. Thus, prevention of IgE binding to FcεRI on these cells is an effective therapy for allergic disease. We have developed a strategy to disrupt IgE binding to FcεRI using an antibody targeting FcεRIα. MATERIALS AND METHODS: Fab fragment antibodies, which lack the Fc domain, with high affinity and specificity for FcεRIα and effective inhibitory activity against IgE-FcεRI binding were screened. IgE-induced histamine, β-hexosaminidase and Ca2+ release in basophils were determined by ELISA. A B6.Cg-Fcer1a(tm1Knt) Tg(FCER1A)1Bhk/J mouse model of passive cutaneous anaphylaxis (PCA) was used to examine the inhibitory effect of NPB311 on allergic skin inflammation. RESULTS: NPB311 exhibited high affinity to human FcεRIα (KD=4 nM) and inhibited histamine, β-hexosaminidase and Ca2+ release in a concentration-dependent manner in hFcεRI-expressing cells. In hFcεRIα-expressing mice, dye leakage was higher in the PCA group than in controls, but decreased after NPB311 treatment. NPB311 could form a complex with FcεRIα and inhibit the release of inflammation mediators. CONCLUSION: Our approach for producing anti-FcεRIα Fab fragment antibody NPB311 may enable clinical application to a therapeutic pathway in IgE/FcεRI-mediated diseases.
