Ixeris dentata var. albiflora Nakai, a herbal plant, is often used to make a strong stomach as an antiphlogistic used when dyspepsia and to improve appetite in Korea and China. And also it is used for adult diseases such as diabetes and liver diseases as Korean traditional medicine. In this study, the composition and DPPH radical scavenging activities of the root of Ixeris dentata var. albiflora Nakai and its effects on cell viability on vero and chang cells were investigated. Moisture, crude ash, crude protein and crude lipid were 79.14, 2.49, 8.28 and 2.56 g/100 g respectively. The highest mineral content was K. The major free sugars were glucose, fructose and sucrose. Major fatty acid are linoleic acid, palmic acid and linolenic acid. Major amino acids were glutamic acid, arginine and aspartic acid and the total contents of amino acids were 28.12 mg/g. The methanol extracts were further fractionated with n-hexane, chloroform, ethylacetate, butanol and water to get an active fraction. In addition, cell viabilities in each fraction were determined. Methanol extract, butanol, and aqueous fraction showed strong survival rates in vero cell and chang cell viability test, and hexane, chloroform, and ethylacetate fraction were examined for toxin in a cell. The root of Ixeris dentata var. albiflora Nakai had scavenging activities against DPPH radicals in a dose-dependent assay. Ethylacetate fraction's SC50 was 6.8 microgram/mL, very strong DPPH radical scavenging activities, but water fraction did not show any activity.

PURPOSE: To identify the effects of a communication program on nursing students' incivility, critical thinking, and clinical practice stress. METHODS: A randomized control group pretest-posttest study was conducted. Fifty randomly selected nursing students were divided into experimental and control groups. A 160-minute communication program was applied to the experimental group and a second survey was conducted two weeks later, shortly after their clinical practice. RESULTS: There was a statistically significant difference in the incivility experienced in the clinical practice after application of the communication program, and refusal in the sub-categories of incivility was statistically significant in this group. CONCLUSION: It is necessary to foster communication skills for nursing students. Communication programs reduce incivility. Therefore, nursing educators need to recognize the importance of communication during clinical practice and consider incorporating it into their regular curricula.

Caveolae are flask-shaped cell-surface membranes, which consist of cholesterol, sphingolipids and caveolin proteins. In a microarray analysis, we found that caveolin-1 (Cav-1) was upregulated by receptor activator of NFkappaB ligand (RANKL), the osteoclast differentiation factor. Silencing of Cav-1 inhibited osteoclastogenesis and also decreased the activation of mitogen-activated protein kinase and the induction of NFATc1 by RANKL. Cav-1 knockdown suppressed the expression of cFms and RANK, two major receptors for osteoclastogenesis. Interestingly, cFms expression was decreased only at the protein level, not at the messenger RNA (mRNA) level, whereas RANK expression was decreased at both the mRNA and protein levels. Furthermore, Cav-1 deficiency increased the lysosomal degradation of cFms. Taken together, these results demonstrate that Cav-1-dependent cFms stabilization contributes to efficient osteoclastogenesis.

Purpose: Proteinuria is a clinical sign of adverse cardiovascular outcomes, including stroke. We aimed to assess the relationship between proteinuria and the occurrence of cerebral infarction. Materials and Methods: In total, 208854 Koreans who participated in the 2009 medical examination were followed up until 2013 using the database of the National Health Insurance Service. The results of urine dipstick tests were utilized to assess proteinuria as absent, 1+, 2+, or ≥3+. The International Classification of Diseases code 163 was used to document cerebral infarction. Results: Between 2009 and 2013, 2383 cases (1.14%) of cerebral infarction occurred during 912772.9 person-years of follow-up. Hazard ratios for incident cerebral infarction increased with inceasing amounts of urine protein from 1.53 (1.23–1.90) in group 2 (1+), 1.67 (1.22–2.28) in group 3 (2+), and 2.66 (1.79–3.96) in group 4 (≥3+), compared to the reference group with little to no detectable urine protein (p<0.001, respectively). Conclusion An increase in urine protein levels was significantly related to the risk of developing cerebral infarction. Our results suggest that proteinuria might be a potential risk factor for cerebral infarction and that urine dipstick test analysis may be clinically useful for predicting stroke.

We report a case of a 75-year-old woman who was diagnosed with dermatomyositis presenting with isolated dysphagia. There were no obvious cranial nerve deficits with normal motor grade in all the limbs in neurological examinations, but a suspicious rash was observed in the anterior chest. The serum creatine kinase was 306 IU/L, and active myopathic changes in bilateral limb muscles were observed in the electromyography test. Muscle biopsy from vastus lateralis showed perivascular infiltration of mononuclear inflammatory cells, which was compatible with dermatomyositis. She had responded to oral prednisolone and azathioprine.

Purpose: This secondary data analysis study evaluated the effects of ICT enhanced home-visit nursing in long-term care insurance on health-related quality of life among community-dwelling older adults. Methods: This study included data of 131 older adults who had experienced a pilot service for ICT enhanced home-visit nursing. ICT enhanced home-visit nursing refers to a method of sharing health records and teleconference between a visiting nurse and a doctor during the home-visit nursing services to community-dwelling older adults. Health-related quality of life and influencing factors were analyzed by t-tests, logistic regression analysis using the Stata 17/SE program. Results: After a pilot service for ICT enhanced home-visit nursing, their health-related quality of life increased. The teleconferencing method had a significant effect on the increase in health-related quality of life. Conclusion The findings indicate a pilot service for ICT enhanced home-visit nursing can be applied to the domestic community-based healthcare service model in terms of health management. In the future, the advanced service model of a pilot service for ICT enhanced home-visit nursing in which subjects conduct detailed for each health problem, and a well-designed evaluation system should be developed.

OBJECTIVES: A stable follow-up participation rate is a very important factor for validity in a cohort study. This study analyzed the factors that affect the participation rate at one hospital-based birth cohort in South Korean. METHODS: The participants were recruited from the Mothers' and Children's Environmental Health study between 2006 and 2010. The analysis targeted 1751 mothers who participated in a birth cohort. We conducted analyses of general characteristics during pregnancy and those of infants at birth that affect the participation rate of the 6-month follow-up survey. RESULTS: The participation rate for the 6-month follow-up survey was 60.4%. The participation rate in the follow-up of the subsequent period decreased within a 5% to 10% range compared to the number of subjects. The participation rate of premature infants was 16.9% lower than that of a full-term infant (52.6% vs. 69.5%). Analysis showed a 16.7% difference between the participation rate of low-birthweight infants in follow-ups (53.7%) and the participation rate of infants with normal weight (70.4%). The participation rate of mothers who were employed during pregnancy was significantly lower for the 6-month follow-up compared to the participation rate of mothers who were unemployed during pregnancy. CONCLUSIONS: In this study, factors such as premature birth, low-birthweight, and the employment status of the mother during pregnancy affected the participation rate of the follow-up survey for the birth cohort at six months. A specific strategy is needed to encourage survey participation for the high risk groups in the follow-ups.

PURPOSE: 'Programming' describes the process that stimulus at a critical period of development has lifelong effects. The fact that low birth weight links to the risk of elevated blood pressures in adult life is well known. This study aims to examine whether this link is evident in the newborn by investigating the relationship of the intrauterine growth indices and neonatal blood pressure(BP). METHODS: We studied 127 neonates who were born at Ewha Womans' Hospital and their mothers enrolled our cohort study during pregnancy. Data on the mothers and details of the birth records were tracked and collected from medical charts. Neonatal BP was measured within 24 hours after birth. RESULTS: Neonatal SBP was positively correlated to intrauterine growth indices; birth weight(BW)(r= 0.4), head circumference(HC)(r=0.4), and birth height(r=0.3). However, an inverse relationship existed, between HC/BW ratio and neonatal SBP(r=-0.4). After adjusting for the baby's sex, maternal BP, and gestational age, neonatal SBP still associated with intrauterine growth indices. SBP was 7 mmHg higher in the highest BW group(> or =90 percentiles) compared to the lowest group(<10 percentiles). On the other hand, SBP was 17 mmHg lower in the highest HC/BW group(> or =90 percentiles) compared in the lowest group(<10 percentiles). CONCLUSION: This study could not find the evidence that intrauterine growth retardation affect on elevated neonatal BP. It suggests that the initiating events of BP programming may occur during postnatal growth period. To identify the critical starting period that intrauterine growth retardation leads to elevated BP, a study tracking BP changes from birth to childhood is required.

We investigated the association between breastfeeding and cognitive development in infants during their first 3 years. The present study was a part of the Mothers' and Children's Environmental Health (MOCEH) study, which was a multi-center birth cohort project in Korea that began in 2006. A total of 697 infants were tested at age 12, 24, and 36 months using the Korean version of the Bayley Scales of Infant Development II (K-BSID-II). The use and duration of breastfeeding and formula feeding were measured. The relationship between breastfeeding and the mental development index (MDI) score was analyzed by multiple linear regression analysis. The results indicated a positive correlation between breastfeeding duration and MDI score. After adjusting for covariates, infants who were breastfed for ≥ 9 months had significantly better cognitive development than those who had not been breastfed. These results suggest that the longer duration of breastfeeding improves cognitive development in infants.

BACKGROUND: Multidisciplinary team care (MTC) is a collaborative approach to treatment plan and ongoing care. We aimed to evaluate the clinical effect of MTC on the regulation of chronic kidney disease-mineral and bone disorder (CKD-MBD) complications in dialysis patients. METHODS: This retrospective observational study was approved by the institutional review board. Among patients who have undergone dialysis at admission, the patients admitted to the nephrology ward were allocated to MTC group, and the others to usual care (UC) group. The MTC group had collaborative care by nephrologists, nurses, pharmacists, and nutritionists. The endpoints were the regulation of corrected calcium (cCa) and phosphate (P), the percent of patients in target level of cCa-P product (cCa×P), and the prescription rate of non-calcium based P-binders. RESULTS: A total of 163 patients were included from January to December 2009. A significant difference was shown in the percentage of patients in target cCa×P level at admission (MTC vs. UC, 81.40% vs. 91.67%; P = 0.038), but there was no significant difference at discharge. During admission, the cCa and P levels of patients in only UC group were significantly changed. In addition, compared with UC group, patients in MTC group were more likely prescribed appropriate P-binders, when they had higher cCa×P levels than 55 mg²/dL² (P <0.001). CONCLUSION: It was found that MTC had beneficial effect on improving the regulation of CKD-MBD and the appropriate phosphate binder uses. Therefore, application of the MTC is anticipated to enhance quality of clinical care in chronic diseases.
