Purpose: The purpose of this study was to explore and assess the experiences of cancer patients and their caregivers who had been admitted to comprehensive nursing care service wards. Methods: Data were collected from 10 patients and 10 caregivers by in-depth interviews. The data were analyzed using content analysis of Downe-Wamboldt. Results: Three categories and seven subcategories were extracted. 1) Realizing institutional limitations of comprehensive nursing care service: ‘Wishing for precise operating systems based on patient severity,’ ‘Anticipating active caregiver participation in treatment process,’ ‘Requiring a countermeasure for safety accidents,’ 2) Professional nursing service which provides relief: ‘Patient-centered professional nursing service,’ ‘Inpatient service that provides relief for patients and caregivers,’ 3) Anticipating continuous use of the service: ‘Inpatient service which users are willing to reuse,’ ‘Wishing for expansion and reinforcement of the service.’ Conclusion Cancer patients and their caregivers experienced institutional limitations while satisfied with professional nursing service and willing to reuse the service. To improve this situation, institutional support such as separate wards for severe patients, measures for active caregiver participation and prevention of safety accidents, and adequate staffing would be helpful for relatively severe level cancer patients and their caregivers.

PURPOSE: We aimed to translate the Test for Respiratory and Asthma Control in Kids (TRACK) instrument into Korean, with subsequent linguistic validation. METHODS: The multistep process of forward translation, reconciliation, back-translation, cognitive debriefing, and proofreading of the Korean version of the TRACK was completed. RESULTS: Two bilingual medical personnel independently translated the original English version of the TRACK into Korean one. After moderating the translation into a single reconciled one, 4 other bilingual persons were invited to translate the Korean draft back into an English one. Discrepancies between the original English version and the back-translated one were reviewed, and the need to modify the reconciled Korean draft was discussed. Twenty caregivers of asthmatic children took part in interviews that examine the appropriateness of the Korean version of the TRACK. The feedback from caregivers were then reviewed by a panel of pediatric allergists and reflected in the final Korean version. The document was finally proofread to check the spelling, grammar, layout and formatting. CONCLUSION: Translation and linguistic validation of the Korean version of the TRACK instrument were completed.

PURPOSE: p21-activated kinases (PAKs) are involved in cytoskeletal reorganization, gene transcription, cell proliferation and survival, and oncogenic transformation. Therefore, we hypothesized that PAK expression levels could predict the sensitivity of pancreatic cancer cells to gemcitabine treatment, and PAKs could be therapeutic targets. MATERIALS AND METHODS: Cell viability inhibition by gemcitabine was evaluated in human pancreatic cancer cell lines (Capan-1, Capan-2, MIA PaCa-2, PANC-1, Aspc-1, SNU-213, and SNU-410). Protein expression and mRNA of molecules was detected by immunoblot analysis and reverse transcription polymerase chain reaction. To define the function of PAK4, PAK4 was controlled using PAK4 siRNA. RESULTS: Capan-2, PANC-1, and SNU-410 cells were resistant to gemcitabine treatment. Immunoblot analysis of signaling molecules reported to indicate gemcitabine sensitivity showed higher expression of PAK4 and lower expression of human equilibrative nucleoside transporter 1 (hENT1), a well-known predictive marker for gemcitabine activity, in the resistant cell lines. Knockdown of PAK4 using siRNA induced the upregulation of hENT1. In resistant cell lines (Capan-2, PANC-1, and SNU-410), knockdown of PAK4 by siRNA resulted in restoration of sensitivity to gemcitabine. CONCLUSION: PAK4 could be a predictive marker of gemcitabine sensitivity and a potential therapeutic target to increase gemcitabine sensitivity in pancreatic cancer.

OBJECTIVES: Although ginseng has been reported to protect neuronal cells and improve various cognitive functions, relationship between ginseng supplementation and response inhibition, one of the important cognitive domains has not been explored. In addition, effects of ginseng on in vivo human brain have not been investigated using the diffusion tensor imaging (DTI). The purpose of the current study is to investigate changes in intrusion errors and white matter microstructure after Korean Red Ginseng supplementation using standardized neuropsychological tests and DTI. METHODS: Fifty-one healthy participants were randomly allocated to the Korean Red Ginseng (n = 26) or placebo (n = 25) groups for 8 weeks. The California Verbal Learning Test was used to assess the number of intrusion errors. Intelligence quotient (IQ) was measured with the Korean Wechsler Adult Intelligence Scale. Depressive and anxiety symptoms were evaluated using Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, and Hopkins Symptom Checklist-25. The fractional anisotropy (FA) was measured from the brain DTI data. RESULTS: After the 8-week intervention, Korean Red Ginseng supplementation significantly reduced intrusion errors after adjusting age, sex, IQ, and baseline score of the intrusion errors (p for interaction = 0.005). Change in FA values in the left anterior corona radiata was greater in the Korean Red Ginseng group compared to the placebo group (t = 4.29, p = 0.04). CONCLUSIONS: Korean Red Ginseng supplementation may be efficacious for improving response inhibition and white matter microstructure integrity in the prefrontal cortex.

OBJECTIVES: The combination extract of four kinds of herbs, Gastrodia elata, Liriope platyphylla, Dimocarpus longan, and Salvia miltiorrhiza, has shown to have memory improving effects in mice. The aim of this study was to investigate the efficacy and safety of the herbal mixture for improving working memory as well as microstructural changes in white matter integrity in individuals with subjective memory complaints. METHODS: Seventy-five individuals with subjective memory complaints were assigned to receive either placebo (n = 15) or herbal mixture (low-dose group, n = 30 and high-dose group, n = 30) supplementation in an 8-week, randomized, double-blind, placebo-controlled clinical trial. Changes in working memory performance and fractional anisotropy (FA) values reflecting white matter integrity from baseline to 8-week endpoint were assessed. RESULTS: The herbal mixture group showed an increase in working memory performance compared to the placebo group (p for interaction = 0.001). In addition, the herbal mixture group showed an increase in FA values in the temporo-parietal regions (corrected p < 0.05), which are crucially involved in working memory function and are among the most affected regions in patients with cognitive impairments. CONCLUSIONS: Findings from this study indicate that the herbal mixture may be a promising therapeutic option for individuals with subjective memory complaints.

PURPOSE: The study was done to examine undergraduate student' suicidal ideation and to identify influences of individual characteristics including psychological resilience and self-control on suicidal ideation. METHODS: Data were collected from 400 students in 11 universities in D city from May 1 to June 30, 2011. Data were analyzed with t-test, one-way ANOVA and Pearson' correlation using SPSS 19.0. RESULTS: Of the students, 11.3% reported suicidal ideation levels higher than average. Woman students and those with high career anxiety, perceived poor health condition and bad relationships showed higher points on suicidal ideation. Suicidal ideation was also negatively correlated with psychological resilience and self-control. CONCLUSION: Over 10.0% of students need careful attention on suicidal ideation, especially counselling service related to suicide prevention for students with poor health, high career anxiety, and bad relationships. Various programs should be developed to promote psychological resilience to improve health and relationships, as well as job guidance for students. It is also suggested the students' experiences be examined to determine how they overcame suicidal ideation.

PURPOSE: Cyclooxygenase (COX)-2 plays an important role in promoting cancer cell proliferation and angiogenesis in human bladder cancer. In this study, we investigated the antitumor or antiangiogenic effects of selective COX-2 inhibitor on N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN)-induced rat bladder tumorigenesis. MATERIALS AND METHODS: Forty male Fischer 344 rats (control) were given only 0.05% BBN, while 40 rats (experimental) were administered 1,500mg/ kg celecoxib once daily and this treatment started from 1 week before their BBN treatment. Ten rats from the control groups and the experimental groups were then sacrificed at 4, 12, 16 and 24 weeks after BBN treatment. We observed all the bladders macroscopically as well as microscopically, and we measured the COX-2 expression in the bladder tissues. Utilizing a cDNA microarray, we analyzed the significant differences of gene expression between the 12 week-control group and the 12 week-experimental group. RESULTS: The incidence of tumor was lower in the experimental group than in the control group from week 12 to week 24. The COX-2 expressions were more significantly decreased via the BBN induction (p<0.05) in the experimental groups than in the control groups after 4 weeks. For the 12 week-experimental group, there were 15 genes altered by the administration of selective COX-2 inhibitor, and the selective COX-2 inhibitor especially regulated transgelin, membrane metallo endopeptidase and apolipoprotein E of these 15 genes to prevent the incidence of bladder tumor. CONCLUSIONS: Selective COX-2 inhibitor has an inhibitory effect on BBN-induced rat bladder tumorigenesis. In the pre-neoplastic phase, selective COX-2 inhibitor regulates transgelin, membrane metallo endopeptidase and apolipoprotein E to prevent the incidence of bladder tumor.

BACKGROUND AND OBJECTIVES: Tilt training as a non pharmacological therapy was recently introduced to treat the patients with neurocardiogenic syncope. Tilt training has been known to prevent neurocardiogenic syncope by desensitizing abnormal autonomic reflex. Herein, the early effect of tilt training and the preventive effect on the relapse of syncope were studied during a long-term follow-up period. SUBJECTS AND METHODS: Fifteen patients (11 males) who experienced recurrent syncope, despite drug treatment or were intolerant to drug treatment, among those diagnosed as neurocardiogenic syncope by the head-up tilt test at Samsung Medical Center between March 2000 and May 2003 were recruited. Each patient underwent tilt training after admission and was educated to continue self-tilt training after discharge. Data for recurrences after discharge were obtained via questionnaires on outpatient visits or by telephone interviews. RESULTS: Eleven (73%) of the 15 who underwent tilt training on admission showed therapeutic effects. The mean follow-up period was 21+/-10 months (5-40 months). Only one patient was excluded due to follow-up loss. Ten of the above patients underwent training by themselves for an average of 4 months after discharge, and experience no relapse of syncope during the follow-up period. CONCLUSION: Tilt training maintained its therapeutic effect during long-term follow-up. This could be a new treatment for patients non responsive or intolerant to medical therapy.
