PURPOSE: The purpose of this study was to explore the role of clinical nursing instructors' lived experience in clinical practicum.METHODS: Data were collected from 11 clinical nursing instructors by in-depth interviews. The data were analyzed using content analysis of Downe-Wamboldt (1992).RESULTS: Four themes and twelve subthemes were extracted. 1) Recognizing and conducting the roles of clinical nursing instructor: ‘Helping and providing support for successful clinical practicum’, ‘Coordinating clinical activities in daily practice’, ‘Providing mentoring as an elder in life’; 2) Participating in improving integrative nursing competency: ‘Helping to improve cognitive competency’, ‘Helping to improve functional competency’, ‘Contributing to form desirable professionalism’, ‘Helping to deliberate the nature of nursing’; 3) Experiencing difficulties in performing the role of clinical nursing instructor: ‘Facing with difficulty from institutional limits’, ‘Recognizing difficulty from lack of personal knowledge and experience’; 4) Experiencing value of clinical nursing instructor and accomplishing personal growth: ‘Making efforts to widen personal knowledge and experience’, ‘Developing one's own educational competency’, ‘Making a chance to reflect oneself’.CONCLUSION: Despite the distinctive features of clinical nursing instructors, little is known of the characteristics. The results of this study could be used as a reference to improve the quality of clinical nursing education.

2.Activated Rac1 regulates the degradation of IκBα and the nuclear translocation of STAT3–NFκB complexes in starved cancer cells.
Experimental & Molecular Medicine 2016;48(5):e231-
In several human tumors, signal transducer and activator of transcription 3 (STAT3) and nuclear factor κB (NFκB) are activated and interact; how these STAT3–NFκB complexes are transported to the nucleus is not fully understood. In this study, we found that Rac1 was activated in starved cancer cells and that activated Rac1 coexisted with STAT3 and NFκB. Rac1 knockdown and overexpression of the dominant-negative mutant Rac1N19 inhibited the degradation of IκBα, an inhibitor of NFκB. MG132, an inhibitor of the ubiquitin proteasome pathway, increased the amount of non-phosphorylated IκBα, but not serine-phosphorylated IκBα, indicating that IκBα degradation by Rac1 in starved cancer cells is independent of IκBα serine phosphorylation by IKK. Rac1 knockdown also inhibited the nuclear translocation of STAT3–NFκB complexes, indicating that this translocation requires activated Rac1. We also demonstrated that the mutant STAT3 Y705F could form complexes with NFκB, and these unphosphorylated STAT3–NFκB complexes translocated into the nucleus and upregulated the activity of NFκB in starved cancer cells, suggesting that phosphorylation of STAT3 is not essential for its translocation. To our knowledge, this is the first study demonstrating the crucial role of Rac1 in the function of STAT3–NFκB complexes in starved cancer cells and implies that targeting Rac1 may have future therapeutic significance in cancer therapy.

Journal of Korean Academy of Psychiatric and Mental Health Nursing 2019;28(2):190-204
PURPOSE: The purpose of this study was to review intervention programs for experienced nurses' job stress and mental health. METHODS: Searches of literature were conducted through four electronic databases (RISS, KISS, PubMed, and CINAHL), focusing on the recent 5-year publications in English or Korean. Thirteen studies were selected for the final analysis and Scottish Intercollegiate Guidelines Network checklist was used to assess methodological rigor and quality. RESULTS: Randomized controlled trials were used in five studies and quasi-experimental designs in eight studies. Cognitive-Behavioral Therapy (CBT) and group approach were the most frequent types of interventions in six and nine studies respectively. On average, the intervention was required for eight weeks and 60~120 minutes per session. After evaluating the effects of CBT, complementary alternative therapy, informative training, simulation training and stimuli control, most of the tested interventions reduced experienced nurses' job stress and improved mental health, but informative training did not. CONCLUSION: Despite the obvious importance of experienced nurses in quality of nursing care, it has not been well studied due to limited numbers of studies with less rigorous design. Study findings provide a basis for developing intervention programs to reduce job stress and improve mental health for experienced nurses.

The Schedule of Fatigue and Anergy/General Physician (SOFA/GP) was developed to screen for prolonged fatigue in the primary care setting. We aimed to evaluate the reliability and validity of the Korean version of the SOFA/GP (SOFA/GP-K), which is adapted from the original English version. We performed translation and back translation, and after conducting a pilot study, we tested the final version of the questionnaire for its reliability and validity in a Korean primary care setting. Two hundred participants that visited a health examination center in a university hospital completed the survey between September and November 2012. A second survey was performed within 2 weeks of the primary survey to test for reliability. We evaluated concurrent validity between the SOFA/GP-K score, the Fatigue Severity Scale (FSS), and Brief Fatigue Index (BFI) scores. The Spearman correlation coefficient between SOFA/GP-K and FSS was 0.71 and 0.61 between SOFA/GP-K and BFI. Internal consistency of SOFA/GP-K was observed (Cronbach's alpha = 0.82) and construct validity was confirmed by factor analysis. The Kappa scores for test-retest reliability for each survey item were between 0.28 and 0.64. The SOFA/GP-K is a valid and reliable questionnaire for screening fatigue in a primary care setting.

Gelatinous transformation of bone marrow is characterized by hypoplasia of fat cells with focal loss of hematopoietic cells and deposition of extracellular gelatinous substances. It is known to be associated with devastating underlying diseases that starve bone marrow. Here, we present a case of a patient whose magnetic resonance (MR) imaging findings of vertebral column were interpreted as metastasis or hematologic malignancy, however, the final diagnosis revealed a gelatinous transformation of bone marrow. This is the first report of gelatinous transformation of bone marrow without evidence of underlying devastating disease.

Background:
Although spinal cord stimulation (SCS) can be a treatment option for intractable postherpetic neuralgia (PHN), obtaining proper stimulation at the thoracic dermatome is difficult. Dorsal root ganglion (DRG) stimulation may be an effective treatment for patients with insufficient efficacy in SCS only.Case: A 54-year-old man with intractable PHN was referred to our clinic. Pain was localized to the distribution of the T1–3 dermatomes. SCS trial was conducted, and lead was placed within the epidural space over the C6–T1 level; however, the stimulation was inadequate for his pain site. Therefore, another lead was placed within the left T1 and T2 DRG for trial, and T1 DRG stimulation provided adequate stimulation. T1 DRG stimulation and SCS could cover the entire pain site with paresthesia, and his pain was decreased by over 50%.
Conclusions
DRG stimulation combined with SCS may be a good treatment option for intractable thoracic PHN.

Objective:
Subjective cognitive decline (SCD) refers to self-reported memory loss despite normal cognitive function and is considered a preclinical stage of Alzheimer’s disease. This study aimed to examine the mediating effects of depression and Instrumental Activities of Daily Living (IADL) on the association between the scoring of Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) and Subjective Cognitive Decline Questionnaire (SCD-Q).
Methods:
A sample of 139 community-dwelling older adults aged 65–79 with normal cognitive function completed the SCD-Q, a comprehensive neuropsychological battery, and functional/psychiatric scales. We conducted 1) a correlation analysis between SCD-Q scores and other variables and 2) a path analysis to examine the mediating effects of depression and IADL on the relationship between CDR-SB and SCD-Q.
Results:
CDR-SB was found to be indirectly associated with SCD-Q, with depressive symptoms mediating this relationship. However, no direct association was observed between SCD-Q and CDR-SB. Additionally, IADL was not associated with SCD-Q and did not mediate the relationship between CDR-SB and SCD-Q. The model fit was acceptable (minimum discrepancy function by degrees of freedom divided [CMIN/DF]=1.585, root mean square error of approximation [RMSEA]=0.065, comparative fit index [CFI]=0.955, Tucker-Lewis index [TLI]=0.939).
Conclusion
Our results suggest that SCD-Q is influenced by depressive symptoms, but not by IADL. The role of depressive symptoms as a mediator between CDR-SB and SCD-Q indicates that psychological factors may contribute to the perception of SCD. Therefore, interventions targeting depression may mitigate the concerns associated with SCD and reduce feelings of worse performance compared to others of the same age group.

Surgery is the standard treatment for a primary gastrointestinal stromal tumor (GIST); however, surgical resection is often not curative, particularly for large GISTs. In the past decade, with imatinib mesylate (IM), management strategies for GISTs have evolved significantly, and now IM is the standard care for patients with locally advanced, recurrent or metastatic GISTs. Adjuvant therapy with imatinib was recently approved for use, and preoperative imatinib is an emerging treatment option for patients who require cytoreductive therapy. IM neoadjuvant therapy for primary GISTs has been reported, but there is no consensus on the dose of the drug, the duration of treatment and the optimal time of surgery. These are critical because drug resistance or tumor progression can develop with a prolonged treatment. This report describes two cases of large rectal malignant GISTs, for which a abdominoperineal resection was initially anticipated. The two patients received IM preoperative treatment; we followed-up with CT or magnetic resonance imaging to access the response. After 9 months of treatment, a multi-disciplinary consensus that maximal benefit from imatinib had been achieved was reached. We determined the best time for surgical intervention and successfully performed sphincter-preserving surgery before resistance to imatinib or tumor progression occurred. We believe that a multidisciplinary team approach, considerating the optimal duration of therapy and the timing of surgery, is required to optimize treatment outcome.

BACKGROUND: Gaucher's disease is an autosomal recessive, lysosomal storage disease caused by mutations of the beta-glucocerebrosidase gene (GBA). There is increasing evidence that GBA mutations are a genetic risk factor for the development of Parkinson's disease (PD). We report herein a family of Koreans exhibiting parkinsonism-associated GBA mutations. CASE REPORT: A 44-year-old woman suffering from slowness and paresthesia of the left arm for the previous 1.5years, visited our hospital to manage known invasive ductal carcinoma. During a preoperative evaluation, she was diagnosed with Gaucher's disease and double mutations of S271G and R359X in GBA. Parkinsonian features including low amplitude postural tremors, rigidity, bradykinesia and shuffling gait were observed. Genetic analysis also revealed that her older sister, who had also been diagnosed with PD and had been taking dopaminergic drugs for 8-years, also possessed a heterozygote R359X mutation in GBA. 18F-fluoropropylcarbomethoxyiodophenylnortropane positron-emission tomography in these patients revealed decreased uptake of dopamine transporter in the posterior portion of the bilateral putamen. CONCLUSIONS: This case study demonstrates Korean familial cases of PD with heterozygote mutation of GBA, further supporting the association between PD and GBA mutation.
