Korean Journal of Occupational Health Nursing 2015;24(3):153-161
PURPOSE: The purpose of this study was to identify the effects of violence experience, emotional labor and job stress on clinical nurses' depression and to provide suggestions for improving the quality of patient care. METHODS: This research involved 257 clinical nurses who were working at an acute care hospital with at least 200 beds in S city and K province. Data were collected from May 23 to June 7 in 2014 and were analyzed using IBM SPSS version 21.0. RESULTS: The results show that 98.1% of subjects had violence experience in the past year and the violence experience included 44.4% physical threat, 37.5% verbal violence and 18.1% physical violence. The average scores were emotional labor 3.57, job stress 3.54 and depression 21.16. There were positive correlations among violence experience, emotional labor, job stress and depression (p<.01). There were also significant co-relationships between depression and violence experience (r=.21, p=.001), between depression and emotional labor (r=.48, p<.001) and between depression and job stress (r=.31, p<.001). CONCLUSION: The results suggest that it is necessary to set up guidelines for clinical nurses to manage violence, emotional labor and job stress in order to create better working environment and to improve quality of patient care.

Type 1 diabetes is on the rise worldwide. Although nutrition education for patients with diabetes has become a routine practice, specifics and impacts of such educations need to be more researched. This study examined the status of nutrition knowledge, dietary attitude, and dietary behavior among children and adolescents with type 1 diabetes (9-19 year-old) and explored factors influencing dietary behaviors related to diabetes by applying the Theory of Planned Behavior. Face-to-face interviews, using a pre-tested structured questionnaire, were conducted with 32 participants (11 boys and 21 girls) with type 1 diabetes followed by a diabetes clinic in a university hospital. This study found that the level of nutrition knowledge related to diabetes was generally low at 4 points out of a possible 10, however, the dietary attitude related to diabetes was found to be generally good at 26 points out of a possible 30. Participants were motivated to follow medical staff recommendations the most; however, their family was also important. Perceived behavioral control was low especially for eating-out and portion control. The dietary behavior related to blood glucose control showed low at 13 points out of a possible 20. Regression analysis showed that perceived behavioral control (p < 0.001) was significantly related to the dietary behavior related to blood glucose control. This rare study with children and adolescents with type 1 diabetes showed that nutrition education should include a component to improve perceived behavioral control through high-risk situation management.

BACKGROUND: The aim of this study was to identify factors associated with mild cognitive impairment (MCI) in older Korean adults with type 2 diabetes mellitus. METHODS: A total of 226 older (age > or =65 years) adults without a history of cerebrovascular disease or dementia participated in this study. Cognitive function was assessed with the Montreal Cognitive Assessment-Korean version (MoCA-K). A MoCA-K score <23 was defined as MCI. RESULTS: The prevalence of MCI was 32.7%. In a logistic regression analysis, age (> or =74 years old vs. 65-68 years old; odds ratio [OR], 3.69; 95% confidence interval [CI], 1.55 to 8.82; P=0.003), educational background (college graduation vs. no school or elementary school graduation; OR, 0.16; 95% CI, 0.05 to 0.46; P=0.001), and systolic blood pressure (> or =135 mm Hg vs. < or =120 mm Hg; OR, 3.25; 95% CI, 1.29 to 8.17; P=0.012) were associated with MCI. CONCLUSION: More concentrated efforts focused on early detection and appropriate management of MCI may be required in older Korean adults with type 2 diabetes mellitus.

BACKGROUND: Melasma is a common acquired hyperpigmentation disorder that predominantly affects the face. It frequently occurs in women with darker skin types and severely impacts quality of life. OBJECTIVE: To characterize the clinicoepidemiological features and triggering or aggravating factors of melasma in Korean patients. METHODS: This cross-sectional study was conducted at the dermatology clinics of five university hospitals in Korea. Between January 2011 and August 2012, 411 patients with melasma completed a questionnaire about the clinical and aggravating factors associated with their melasma. RESULTS: The study population consisted of 400 women and 11 men aged 22~73 years (mean age, 42.8±9.92 years). Triggering or aggravating factors were sun exposure (68.4%), pregnancy (27.0%), and emotional stress (24.8%). Interestingly, 61.1% of patients complained of sensitive/inflammatory features such as erythema, itching, and a stinging sensation. Dryness was the most common aggravating factor, followed by erythema/redness and itching/stinging. Concomitant pigmentary disorders included post-inflammatory hyperpigmentation in 15.1% of patients, followed by pigmented contact dermatitis, and acquired bilateral nevus of Ota-like macules. CONCLUSION: It is well known that sun exposure and hormonal changes are the most common triggers of melasma; however, sensitive/inflammatory features may aggravate melasma in East Asian patients. Therefore, these individual and racial differences should be considered in the prevention and treatment of melasma.

PURPOSE: Regulatory T (Treg) cells are key modulators in the immune system. Recent studies have shown that atopic dermatitis (AD) patients have higher numbers of Treg cells; however, little is known about the specific phenotype and function of Treg cells in AD. MATERIALS AND METHODS: To identify differentially expressed proteins in peripheral induced Treg cells in AD and naturally derived Treg cells in normal controls, CD4?CD25? Treg cells were isolated from thymus tissue of normal mice and the spleens of AD mice. Membrane proteins were extracted, and quantitative proteomics labeling with Tandem Mass Tags (TMT) was performed, followed by one-dimensional liquid chromatography/tandem mass spectrometry analysis. RESULTS: Using TMT labeling, we identified 510 proteins, including 63 membrane proteins and 16 plasma membrane proteins. CD47 was one of the upregulated proteins in Treg cells in AD spleens. Although CD47 was expressed in all CD4? and CD8? T cells, a significantly higher expression of CD47 was observed in the Treg cells of AD mice and AD patients than in those of normal mice and healthy controls. Furthermore, Treg cells from the spleen showed a significantly higher expression of CD47 than those from the thymus. CONCLUSION: We found that CD47 is highly expressed in the Treg cells of AD mice, particularly in the spleen. Based on our results, we propose that CD47(high) Treg cells are likely induced Treg cells and that upregulated CD47 in the Treg cells of AD patients may play a role in the increased population of Treg cells in AD.

Background:
Airborne particulate matter (PM), a widespread air contaminant, is a complex mixture of solids and aerosols composed of particles suspended in the air. PM is associated with inflammatory responses and may worsen inflammatory skin diseases. However, the mechanisms through which PM affects atopic dermatitis (AD) remain unclear.
Objective:
To establish an In Vitro model that more accurately mimics AD using human keratinocyte (HaCaT), dermal fibroblast (HDF), and mast cell (HMC-1) and using this model to investigate the mechanism through which PMs affect AD.
Methods:
An AD-like In Vitro model was established by seeding HaCaT, HDF, and HMC-1 cells with recombinant human interleukin (IL)-1α and polyinosinic:polycytidylic acid.We confirmed the effect of PM on the inflammatory cytokine expression of a triple-cell culture model. SRM 1649b Urban Dust, which is mainly composed of polycyclic aromatic hydrocarbons, was used as the reference PM. The effects of PM on the expression levels of proinflammatory cytokines and skin barrier markers were assessed using quantitative real-time polymerase chain reaction and western blotting. Inflammatory cytokine levels were measured using an enzyme-linked immunosorbent assay.
Results:
Interactions between various skin cell types were evaluated using a co-culture system. PM treatment increased mRNA and protein levels of the inflammatory cytokines IL-6, IL-1α, tumor necrosis factor-α, IL-4, and IL-1β and decreased the expression of the skin barrier markers filaggrin and loricrin.
Conclusion
Our results suggest that an In Vitro triple-cell culture model using HaCaT, HDF, and HMC-1 cells may be reliable for obtaining more physiological, functional, and reproducible data on AD and skin barriers.

Haemorrhagic fever with renal syndrome (HFRS) caused by Hantaan viruses has been one of the principal acute febrile disease in Korea. To analysis the sero-epidemiological patterns of HFRS, 4,177 patient sera of acute febrile illness submitted for serological assay to National Institute of Health from Community Health Centers, Institutes of Health and Environment and hospitals from 1996 to 2005 were examined for antibodies against Hantaan virus by indirect immunofluorescent assay (IFA). Serum samples with greater than 1:32 antibody titer were considered positive. The results were analyzed seroepidemiologically by annual, sexual, seasonal, age and regional distribution of HFRS patients. Out of 4,177 serum samples tested, 1,415 samples (33.9%) were positive to Hantaan virus. The ratio of males (48.2%, 682/1,415) to females (38.2%, 541/1,415) was 1.3:1. Seasonal incidence showed that 69.5% (985/1,415) of cases occurred from October to December, resulting with higher prevalence in November (41.3%, 584/1,415). Regionally, seropositive rates of samples collected in Gyenggi, Gangwon and Chungbuk were 39.9% (564/1,415), 19.3% (274/1,415) and 8.5% (120/1,1415), respectively. Age distributions of seropositive of HFRS were detected from 20 to 79 years (78%).

BACKGROUND/AIMS: In spite of increased concerns about the overlaps among the various functional gastrointestinal disorders (FGIDs), studies for the overlap between constipation and other common FGIDs are rare. Therefore, we investigated the patterns of overlaps between constipation and other common FGIDs. METHODS: This study was designed as a prospective nationwide multi-center questionnaire study using Rome III questionnaires for functional dyspepsia (FD), irritable bowel syndrome (IBS), and functional constipation (FC), as well as various questionnaires about patients’ information, degree of symptoms, and quality of life. For the evaluation of gastroesophageal reflux disease (GERD), GERD-Q was used. RESULTS: From 19 centers, 759 patients with constipation were enrolled. The proportions of FC and IBS subtypes of constipation (IBS-C) were 59.4% and 40.6%, respectively. Among them, 492 (64.8%) showed no overlap. One hundred and thirty-six patients (17.9%) presented overlapping GERD, and 80 patients (10.5%) presented overlapping FD. Fifty one (6.7%) of patients were overlapped by both GERD and FD. Coincidental herniated nucleus pulposus (HNP) (P = 0.026) or pulmonary diseases (P = 0.034), reduced fiber intake (P = 0.013), and laxative use (P < 0.001) independently affected the rate of overlaps. These overlapping conditions negatively affected the constipation-associated quality of life, general quality of life, and degree of constipation. CONCLUSIONS: The overlap of GERD or FD was common in patients with constipation. Coincidental HNP or pulmonary diseases, reduced fiber intake, and laxatives use were found to be independent associated factors for overlapping common FGIDs in Korean patients with constipation.

Cyclosporine is an immunosuppressive agent that plays an important therapeutic role for organ transplantation. However, complications due to type 1 renal tubular acidosis, albeit rare, have been reported. We experienced a case of severe metabolic acidosis associated with cyclosporine administration after renal transplantation. A 54-year old man was hospitalized for seizure, confusion and weakness. He demonstrated severe metabolic acidosis and hypokalemia. Continuous renal replacement therapy was started and sodium bicarbonate was administered to correct the acidosis and the dosage of cyclosporine was reduced. Thereafter, the cyclosporine level in whole blood decreased gradually, and the metabolic acidosis improved.
