While many studies have addressed the Korean nurse immigration to Germany in 1960s-70s in terms of the nurses' personal histories from a national perspective, few studies have pointed to its transnational impact on the medical field. Given this gap, the paper discusses its significance in the medical history through examining the nursing culture and policy changes made in both countries initiated by the immigration of the qualified Korean nurses. For this end, the paper first discusses differences between Korea and Germany in the nursing culture and professional standards at the time of the nurse immigration. The study then examines the transnational changes in the two nations in the nursing professional culture and related policies including nurse education and qualification process. More specifically, the paper argues that the Korean female nurses not only supplied labor in need but also contributed to the medical policy changes in Germany. The prevalent stereotype of nursing as a non-professional field in the German society begin to change while experiencing professionally qualified Asian immigrant nurses and practiced treatments that had been conduced by German doctors by then. This observation actually leads to the policy level reforms in nursing education and qualification process to meet the need of high-quality nurses when the labor immigration was stopped in mid-1970s. The paper also points out that the influence of the nurse immigration on the Korean society is not merely economic; it brought the policy level reforms in nurse education and qualification as well. The immigration, resulting in a lack of nurses in the Korean society, triggered two main responses: the expansion of the existing nurse education system and the establishment of a new system called "nursing assistant."

BACKGROUND: Direct observation of healthcare workers is commonly used in hospitals to investigate hand hygiene compliance. However, the hand hygiene compliance rate may increase due to the Hawthorne effect, which is the modification of behavior simply because subjects become aware that they are being observed. The objective of this study was to investigate the occurrence of the Hawthorne effect when directly observing hand hygiene compliance in intensive care unit (ICU) healthcare personnel. METHODS: A total of 87 staff members from the coronary care unit and cardiac surgery ICU of a general hospital in Seoul were included in this study: 24 residents and interns, 55 nurses, and 8 nursing assistants. Both covert and overt observations, where subjects were either unaware or aware of any direct observation, were performed on separate occasions. RESULTS: A total of 1,052 covert and 1,336 overt observations were documented over 30 and 34 occasions, respectively. Overall hand hygiene compliance was significantly higher with overt observation than with covert observation (1,041/1,336, 77.9% vs. 659/1,052, 62.6%, P<0.001). The Hawthorne effect was present in all professions and behaviors, with the exception of nursing assistants, and prior to touching a patient. CONCLUSION: Direct observation of hand hygiene compliance was associated with the Hawthorne effect when observations were made overtly and this was likely to contribute to an overestimation of compliance rate.

OBJECTIVES: The aims of this study were to investigate the pattern of stress coping strategies and the effects of stress coping strategies on quality of life in patients with schizophrenia. METHODS: Stress coping strategies and quality of life were examined using Ways of Coping Checklist and Schizophrenia Quality of Life Scale for 98 patients with schizophrenia. Stress coping strategies were composed of problem-focused coping, social support seeking, emotion-focused coping, and wishful thinking. Among these, problem-focused coping and social support seeking were active coping strategies while emotion-focused coping and wishful thinking were passive coping strategies. Positive and Negative Syndrome Scale (PANSS) and Beck's Depression Inventory (BDI) were also administered. RESULTS: Active coping scores were higher than passive coping scores in patients with schizophrenia. Quality of life was higher in the active coping group compared to the passive coping group. Active coping usage was a significant predictor of higher quality of life even after controlling for gender, age, PANSS, and BDI scores. CONCLUSION: Patients with schizophrenia used more active coping strategies than passive coping strategies, which showed significant association with higher quality of life. A treatment program to provide education on use of active coping strategies in a proper and flexible way might contribute to enhanced quality of life in patients with schizophrenia.

Colorectal cancer is the third most common cause of cancer related death in the world. Multiple lines of evidence suggest that there is an association between consumption of dietary fat and colon cancer risk. Not only the amount but also the type and the ratio of fatty acids comprising dietary fats consumed have been implicated in the etiology and pathogenesis of colon cancer. Omega-3 (n-3) polyunsaturated fatty acids (PUFAs), such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), have been known to inhibit development of colon cancer by downregulating the expression of genes involved in colon carcinogenesis and also by altering the membrane lipid composition. Data from laboratory, epidemiological, and clinical studies substantiate the beneficial role of n-3 PUFAs in preventing colitis and subsequent development of colon cancer. In addition, recent studies suggest that some n-3 PUFAs can be effective as an adjuvant with chemotherapeutic agents and other natural anticancer compounds in the management of colon cancer. In this review, we discuss chemopreventive and therapeutic effects of fish oil derived long chain n-3 PUFAs, particularly EPA and DHA, with focus on synergetic effects of which they exert when combined with chemotherapeutic agents and other natural compounds.

BACKGROUND: This study evaluated the clinical characteristics and risk factors associated with community and hospital onset MRSA isolated from patients admitted to a tertiary care teaching hospital. METHODS: The study was carried out on MRSA isolated from clinical specimens of patients admitted into the wards and the intensive care unit in a 2,200-bed tertiary care teaching hospital from January 1st through December 31st, 2007. In order to identify the risk factors associated with MRSA acquisition, the medical records were reviewed. All statistics were computed using SPSS version 14.0. RESULTS: Of the 835 MRSA isolates, 179 (21.4%) were CO-MRSA and 656 (78.6%) were HO-MRSA. Of the 179 CO-MRSA isolates, 6 (3.4%) were CA-MRSA. Multiple logistic regression analysis showed that a history of using medical device or antibiotics within 1 year before the isolation of MRSA were significant risk factors for HO-MRSA, and a history of hospitalization within 1 year before the isolation of MRSA was a significant risk factor for CO-MRSA. Analysis on the antibiotics administered within 1 year before the isolation of MRSA showed that levofloxacin, macrolides, 1st generation cephalosporins, 3rd generation cephalosporins, 4th generation cephalosporins, vancomycin, metronidazole, and carbapenem were all significant risk factors for HO-MRSA and that TMP/SMX was a significant risk factor for CO-MRSA. Of the 6 (3.4%) CA-MRSA isolates, 1 (16.7%) was the pathogen responsible for soft tissue infection. No patients died from the CA-MRSA infection. CONCLUSION: MRSA isolated from clinical specimens of patients admitted into the wards and the ICU in a tertiary care teaching hospital was usually HO-MRSA, CO-MRSA and HO-MRSA usually had at least one of the risk factors associated with MRSA acquisition, and CO-MRSA was mainly HACO-MRSA.

PURPOSE: Toll-like receptor 3 (TLR3) recognizes to viral double-stranded RNA and is involved in antiviral defenses. A probable role of TLR3 gene variants in the pathogenesis of aspirin-intolerant asthma (AIA) has been suggested. AIA patients present more frequent asthma exacerbations in which respiratory viral infections could be an exacerbating factor. IgG subclass deficiency was commonly present with bronchial asthma. Based on previous findings, we investigated whether TLR3 variants could affect IgG3 subclass deficiency in AIA. METHODS: We enrolled 279 AIA patients, 403 aspirin-tolerant asthma (ATA) patients, and 315 normal healthy controls (NC) in this study. TLR3 polymorphism at the promoter region -299698G>T was genotyped. The serum levels of IgG subclasses were determined by the single radial immunodiffusion method. Expressions of IgG3 and TLR3 on Epstein-Barr virus transformed-B cells isolated from asthmatic patients were evaluated by flow cytometry to investigate B-cell functions. RESULTS: The TLR3 -299698 T allele was significantly associated with severity and IgG3 deficiency in the AIA group (P=0.044 and P=0.010, respectively), but not in the ATA group. IgG3 expression on B cells from asthmatics with IgG3 deficiency was significantly lower compared to those without (P=0.025). There was a positive correlation between IgG3 expression levels on B cells and serum IgG3 levels (r 2=0.434, P=0.002). CONCLUSION: These results suggest that the TLR3 -299698G>T polymorphism may be associated with IgG3 subclass deficiency and severity in AIA.

Theca cell tumors of the ovary have been generally regarded as almost invariably benign neoplasms. Even though several case reports of the malignant variant of this tumor have appeared in the world literature, but the term "malignant thecoma" is controversial and doubtful. If a thecoma ever becomes malignant, the tumor cells dedifferentiate so that they can not be recognized any longer as theca cells: instead, they proliferate as a stromal sarcoma or fibrosarcoma. We have experienced a rare case of ovarian low-grade stromal sarcoma with thecomat ous features in a 66-year-old postmenopausal woman. The clinicopathologic finding and a review of literature on ovarian stromal sarcoma and malignant thecoma were described brie fly.

OBJECTIVE: This study aimed to determine the association between preeclampsia and the postpartum development of metabolic syndrome based on the pre-pregnancy status. METHODS: Korean women who delivered their first child between January 1, 2011, and December 31, 2012, were enrolled. All subjects underwent a national health screening examination conducted by the National Health Insurance Corporation 1 or 2 years prior to their first delivery and within 2 years after their first delivery. RESULTS: Among the 49,065 participants, preeclampsia developed in 3,391 participants (6.9%). The prevalence of metabolic syndrome was higher postpartum in women with preeclampsia than in those without preeclampsia (4.9% vs. 2.7%, respectively, P<0.001). Through the pre-pregnancy to postpartum period, women with preeclampsia had a greater increase in gestational weight retention, body mass index, waist circumference, systolic blood pressure, and triglyceride levels and a greater decrease in high-density lipoprotein cholesterol levels than women without preeclampsia. Preeclampsia was associated with an increased risk of the postpartum development of metabolic syndrome in women without pre-pregnancy metabolic syndrome (odds ratio, 1.28; 95% confidence interval, 1.05–1.56). However, preeclampsia was not associated with postpartum metabolic syndrome in women with pre-pregnancy metabolic syndrome or 2 components of metabolic syndrome. CONCLUSION: In this study, preeclampsia was associated with the postpartum development of metabolic syndrome in women without pre-pregnancy metabolic syndrome. However, the effects were attenuated by predisposing risk factors in the pre-pregnancy period.

A hemodialysis room is the healthcare facility utmost demanding an infection control because dialysis patients have chronic serious underlying conditions and high risks of bloodborne infection due to a indwelling intravascular catheter, a frequent exposure to bloods or body fluids, and a blood transfusion as well as a hemodialysis room can be a mixing vessel to encounter both hospital-acquired pathogens and community-acquird pathogens. Therefore the Korean Society for Nosocomial Infection Control (KOSNIC) purposed to develop a guideline for the infection control in a hemodialysis room with support of Korean Center for Disease Control (KCDC). This guideline was composed of 11 chapters including vascular access control, dialysis water, microbiological and chemical monitoring of dialysis water and dialysates, components and passage of dialysates, maintenance of dialysis machines, disinfection, waste management, infection surveillance, aseptic techniques and standard precaution, environmental control, prevention of bloodborne infections and 5 appendices composing basic infection control techniques. This is the first official guideline approved by KOSNIC and KCDC of the infection control in a hemodialysis room in Korea. Here the guideline was published except appendices and entire guideline including those can be downloaded on hompages of KOSNIC (http://www.kosnic.org/) and KCDC (http//www.cdc.go.kr/).

BACKGROUND: Staphylococcus aureus is a major bacteremia-causing pathogen in hemodialysis patients, frequently colonizing patient skin and mucosa. Active infection control is necessary to prevent methicillin-resistant S. aureus (MRSA) infection in hospitals; however, the spread of community-associated MRSA has recently become a concern for MRSA infection control. We evaluated the nasal colonization of MRSA among hemodialysis patients and the molecular characterization of the MRSA isolates. METHODS: Nasal swabs were obtained from 482 hemodialysis patients in 7 nationwide hospitals in November 2009, and cultured for MRSA colonization. Swabs were inoculated and cultured in 6.5% NaCl tryptic soy broth, then subcultured on MRSASelect medium (Bio-Rad, Hercules, CA) for 20-24 h. Multiplex PCR was performed to analyze staphylococcal cassette chromosome mec (SCCmec) types of MRSA isolates. RESULTS: Of 482 hemodialysis patients, 57 (11.8%) carried MRSA, ranging from 6.7% to 19.0%. Among the 57 MRSA isolates, we identified 3 (5.3%) SCCmec II, 1 (1.8%) SCCmec IIA, 30 (52.6%) SCCmec IIB, 1 (1.8%) SCCmec III, 6 (10.5%) SCCmec IV, and 16 (28.1%) SCCmec IVA subtypes. CONCLUSION: The MRSA carriage rate (11.8%) of hemodialysis patients in this study was high. The SCCmec IIB subtype, a healthcare-associated strain, was the predominant strain, although SCCmec IV isolates, typically found in community-associated MRSA infections, were also frequently observed. To prevent healthcare-associated MRSA infections in hemodialysis patients, standardized infection control measures should be performed, and efforts to reduce MRSA carriage rates should be considered.
