1.Factors Affecting Organizational Commitment and Turnover Intention of Hospital Nurses: Focused on the Mediating Effects of Person-environment Fit.
Journal of Korean Academy of Nursing Administration 2013;19(3):361-371
PURPOSE: This study was done to investigate the factors affecting organizational commitment and turnover intention of hospital nurses. Empirical analysis on the mediating effect of the person-environment fit of organizational commitment and turnover intention and factors affecting this relationship were also examined. METHODS: Participants were nurses working in 4 university hospitals in Seoul or Busan. Data were collected between July 27 and Aug. 10, 2012 and for the final analysis, 393 data sets were used. The fitness of models were tested using AMOS 19.0. RESULTS: The fitness of the modified model showed high compatibility with the empirical data. In the modified model, organizational climate, professional self-concepts and person-organization fit were found to have significant effects on hospital nurses' organizational commitment. Professional self-concepts, personality, person-organization fit and person-job fit significantly affected hospital nurses' turnover intention. There was the mediating effect of person-organization fit between organizational commitment and turnover intention and factors affecting the relationship. But person-job fit was not found to have a mediating effect. Organizational commitment accounted for 49.8% and turnover intention for 39.9% of covariance in these factors. CONCLUSION: Nursing strategy for enhancing professional self-concepts and person-organizational fit should be planned by nursing managers.

Among the precancerous lesions, dysplasia of the uterine cervix and adenoma of the colon have been widely studied in terms of genetic alterations. However, little has been performed regarding phenotypic alterations of the precancerous lesions. We investigated the relationship among cellular proliferation, clonality, immortality and histopathologic grading of the squamous epithelial lesions of the uterine cervix. Proliferation index (PI) was calculated based on the ratio of the epithelial cells positive for proliferating cell nuclear antigen to the total epithelial cells. Clonality was assayed by X-linked HUMARA polymorphism. For immortality assay, PCR-based TRAP (telomeric repeat amplification protocol) was done and telomerase processivity was calculated by comparison with the positive control. PI increased gradually as the lesions advanced from dysplasia to invasive carcinoma. Among informative case, all of the carcinoma in situ showed monoclonal pattern (7 of 7). Among invasive squamous cell carcinoma, 6 cases showed monoclonal pattern and 2 cases polyclonal pattern. TRAP reaction was positive in 92.6% (25 of 27) of dysplasia (high grade: 14 of 15; low grade: 11 of 12), 95.0% (19 of 20) of carcinoma in situ, 100% (9 of 9) of microinvasive carcinoma, and 92.9% (13 of 14) of invasive carcinoma. It was also positive in 12 of 12 samples of chronic cervicitis or squamous metaplasia near the lesions of dysplasia. There was no difference in TRAP positivity among the dysplasia, carcinoma in situ and invasive carcinoma, whereas telomerase processivity showed significant correlation. These results suggest that proliferative activity and telomerase processivity may be progressive events in oncogenesis, although telomerase activation may be an early event.

A 56 year old female was admitted because of the right upper quadrant mass for 4 days. She complained of intermittent colicky RUQ pain, fever and chills. So diagnostic procedures was performed: Blood chemistry testings. Ultrasonography. Barium enema, Liver scan, Hepatobiliary scan, ERCP and Abdomen CT, which diagnosed as gall bladder carcinoma. So explolaparotomy was performed and gross operative finding was gall bladder carcinoma with metastatic lymph node and cystic duct stone. So cholecystectomy, hemigastrectomy and anterior segmentectomy of right liver was done. But the biopsy result was cystic duct stone, cholecystitis and gall bladder empyema.

BACKGROUND/AIMS: To evaluate the era of direct acting antivirals (DAAs), we must understand the treatment patterns and outcomes of interferon-based therapy for hepatitis C virus (HCV) infection. We aimed to elucidate the treatment rate, factors affecting treatment decisions, and efficacy of interferon-based therapy in a real-world setting. METHODS: This nationwide cohort study included 1,191 newly diagnosed patients with chronic HCV infection at seven tertiary hospitals in South Korea. Subjects were followed retrospectively until March 2015, which was just before the approval of DAA therapy. RESULTS: In total, 48.2% and 49.3% of the patients had HCV genotypes 1 and 2, respectively. Interferon-based therapy was initiated in 541 patients (45.4%). The major reasons for no treatment included ineligibility (18.9%), concern about adverse events (22.3%), cost (21.5%), and an age >75 years (19.5%). Interferon-based therapy was discontinued (18.5%) mainly due to adverse events (n=66). The intent-to-treat analysis found that the sustained virologic response (SVR) rate was 58.3% in genotype 1 patients and 74.7% in non-genotype 1 patients. CONCLUSIONS: Approximately one-third of newly diagnosed HCV patients in South Korea received interferon-based therapy and showed a suboptimal SVR rate. Diagnosis of patients at younger ages and with a less advanced liver status and reducing the DAA therapy cost may fulfill unmet needs.

Background:
/Aim: This study aimed to establish the real-world effectiveness and safety of grazoprevir/elbasvir (EBR/GZR) therapy in South Korea.
Methods:
A total of 242 patients with chronic hepatitis C virus (HCV) genotype 1 or 4 infection who started EBR/GZR were consecutively enrolled from seven tertiary hospitals. Retrospective analysis of the fractions of patients that achieved sustained virological response (SVR) was performed, and the incidence of adverse events was noted.
Results:
The mean age of enrolled patients was 59.0 ± 12.6 years and 47.5% were males. Patients with HCV genotype 1b accounted for 93.8% (n = 227), and patients with HCV of unspecified genotype 1 accounted for 5.8% (n = 14). Hypertension was the most common comorbid disease (29.8%) followed by diabetes (22.7%) and chronic kidney disease (CKD, 12.4%). SVR rates of treatment-naïve and treatment-experienced patients were 85.5% (182/213) and 93.1% (27/29), respectively, in the intention-to-treat analyses, whereas in the per-protocol analyses, those were 97.8% (179/183) and 100% (28/28), respectively. Fewer patients with HCV genotype 1 of unspecified subtype achieved SVR (81.8%, n = 11) compared to the patients with SVR infected with genotype 1b (99%, n = 198, p < 0.001). All patients with CKD showed SVR. Itching (12%) and dyspepsia (4.1%) were common adverse events. Of the four patients who discontinued the antiviral therapy, one experienced mild fatigue but neither treatment withdrawal was because of an adverse event.
Conclusions
EBR/GZR showed high real-world effectiveness and safety in Korean patients with chronic HCV infection regardless of the previous antiviral treatment, liver cirrhosis, or CKD status.

BACKGROUND/AIMS: This study aimed to describe the health-related quality of life (HRQoL) outcomes for Korean chronic hepatitis C patients and to investigate the impact of patient and virus-related factors on HRQoL. METHODS: HRQoL was assessed in 235 hepatitis C virus (HCV)-infected patients from seven nationwide tertiary hospital, including those with liver cirrhosis and hepatocellular carcinoma (HCC), using the Shor-Form 36 (SF-36) version 2 and the European quality of life questionnaire-5 dimensions (EQ-5D-3L). RESULTS: The SF-36 physical (48.8±8.3) and mental (46.2±11.7) component summary scores of the HCV-infected patients were below normal limits. Of the eight domains, general health, vitality, and mental health tended to show low scores. Patients with decompensated cirrhosis had the lowest HRQoL, while HCC and chronic hepatitis patients had similar HRQoL results. The EQ-5D index was low (0.848±0.145) in the HCV infected patients. Multivariable analysis showed age ≤65 years, high monthly family income (>$2,641), low comorbidity score, and sustained virologic response (SVR) were independently associated with favorable HRQoL. CONCLUSIONS: HRQoL in Korean patients with chronic HCV infection was low and was affected by cirrhosis severity, SVR, and comorbidity as well as income, which had the strongest effect. Therefore, HRQoL may be improved by antiviral therapy with reasonable costs to prevent cirrhosis progression.

Background/Aims:
Sofosbuvir (SOF)-based therapy has been used in Korean patients with chronic hepatitis C virus (HCV) infection since January 2016. This study aimed to in-vestigate the real-life effectiveness and safety of SOF-based therapy in genotype 2 HCV infection.
Methods:
From January to December 2016, 458 genotype 2 HCV-infected patients who received ≥1 dose of SOF-based therapy were consecu-tively enrolled in seven tertiary hospitals. Sustained virologic response (SVR) rates and safety were determined by inten-tion-to-treat (ITT) and per-protocol (PP) analyses.
Results:
The mean age of the patients was 61.0 years; 183 (40%) were male, and 13.1% showed a high viral load (>6,000,000 IU/ mL). Among the 378 treatment-naïve patients, the SVR rates were 94.2% (ITT) and 96.7% (PP). Among the 80 treatmentexperienced patients, the SVR rates were 96.3% (ITT) and 98.7% (PP). Patients with a relatively high fibrosis-4 index score (>3.25) had similar SVR rates to those with a relatively low score (p=0.756). A total of 314 patients (68.6%) were treated with a reduced ribavirin dose at the prescriber’s dis-cretion, but they showed similar SVR rates to those treated with the weight-based dose (ITT: 95.5% and 92.3%, PP: 97.4% and 96.3%, respectively). Adverse events were ob-served in 191 patients (41.7%), including 86 (18.8%) with anemia, but only one (0.2%) discontinued antiviral therapy due to nausea.
Conclusions
SOF-based therapy showed high real-life efficacy and tolerability in Korean patients with genotype 2 chronic HCV infection, regardless of previous antiviral treatment experience and fibrosis score. A reduced ribavirin dose can be considered in this patient cohort.

BACKGROUND/AIMS: This study investigated the role of single nucleotide polymorphisms (SNPs) near the interleukin-28B (IL28B) gene with respect to clinical outcomes and the antiviral response in hepatitis C virus (HCV) infection to suggest the practical utility of IL28B genotyping in Korea. METHODS: Two SNPs near IL28B, rs12979860 and rs8099917, were analyzed using an allelic discrimination assay in a total of 454 individuals, including 147 health-check examinees and 307 patients with HCV infection. RESULTS: The CC genotype frequency was significantly higher in the spontaneous recovery group than in the chronic infection group and was higher in the chronic hepatitis group than in the liver cirrhosis or hepatocellular carcinoma group, suggesting its favorable role in the clinical outcome. Multivariate analysis revealed that the rs12979860 CC genotype was an independent predictor of sustained virologic response (SVR) in genotype 1 HCV infection. During the currently used response-guided therapy, IL28B genotyping was most helpful for the patients who exhibit early virologic responses without rapid virologic responses, as those patients exhibiting the non-CC type did not achieve SVR, although they represented approximately one-third of the total patients. CONCLUSIONS: The IL28B SNP is an independent predictor of SVR. Our results may be helpful if the findings are carefully applied to select patients in Korea.

BACKGROUND/AIMS: The prevalence of hepatitis C virus (HCV) infection in Korea exhibits significant geographic variation, with it being higher in Busan and Jeonam than in other areas. The reason for this intranational geographic difference was investigated in this study by conducting a comparative analysis of the risk factors related to HCV infection among three geographic areas: the capital (Seoul), Busan, and the province of Jeolla. METHODS: In total, 990 patients with chronic HCV infection were prospectively enrolled at 5 university hospitals located in Seoul (n=374), Busan (n=264), and Jeolla (n=352). A standardized questionnaire survey on the risk factors for HCV infection was administered to these three groups of patients, and a comparative analysis of the findings was performed. RESULTS: The analysis revealed significant regional differences in exposure to the risk factors of HCV infection. By comparison with patients in Seoul as a control group in the multivariate analysis, patients in Busan had significantly more experience of invasive medical procedures, acupuncture, cosmetic procedures, and multiple sex partners. In contrast, patients in Jeolla were significantly older, and they had a higher prevalence of hepatocellular carcinoma, a lower prevalence of multiple sex partners, and had experienced fewer invasive procedures. CONCLUSIONS: There was a significant geographic difference in the exposure to potential risk factors of HCV infection between patients from the three studied regions. This may explain the regional variation of the prevalence of HCV infection in Korea, and should be taken into account when planning strategies for the prevention and management of HCV infection.

In 1861 Rokitanski laid down the law that the pyloric ring served as a barrier to the duodenal spread of gastric cancer. Although this theory was generally accepted, direct spread of gastric carcinoma into the duodenum has been reported. We report a case of gastric cancer spreading into the duodenum that was diagnosed by endoscopic duodenal biopsy and review the literature.
