This study was performed to assess the effect of one year's of meal service for home-staying urban elderly with low incole on their nutritional status. One hundred and eighty three subjects, who had already completed the first nutritional survey, were assigned to two group : meal served(served) and non-meal served(non-served). A meal containing approximately on half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After on year of meal service, follow-up-nutritional survey was done and changes of parameters were analyzed with paired t-test. Served female showed signficantly increased intake of riboflavin and calcium, while non-served female showed significantly decreased intake of calcium. Serum total protein, serum albumin and serum cholesterol were significantly increased in female regardless of meal service. Served remale was observed with significantly elevated LDL-cholesterol, whereas non-served female showed singnificantly lowered HDL-cholesterol. Significantly decreased serum iron, serum transferrin saturaion and significantly increased TIBC were observed for female regardless of meal service. But the proportion of anemic elderly according to Hb or serum iron was decreased more in served group. Female showed significantly increased serum zinc and copper regardless of meal service, whereas only served male showed significantly increased serum copper.

PURPOSE: The purpose of this study was to describe the essential structure of the lived experience of working mothers' parenting burden in Korea. METHODS: Eight working mothers with young children were interviewed. The Colaizzi analysis of phenomenological research was applied. RESULTS: Seven theme clusters were extracted: a life with constant conflict, sense of guilt, feeling anxious because of lack of information about education for their children, social stigma as a deficient mother, family relationship becoming distant, a life being exhausted, day to day struggle. CONCLUSION: These results provide an opportunity to have a better understanding of the experiences of working mothers related to parenting their young children. It would also serve as a medium for the formulation of appropriate nursing intervention relevant to burdens of parenthood.

PURPOSE: The study purposes were to describe the process of developing the Korean versions of the Six Dimension Scale of Nursing Performance (Six-D) and Student Nurse Stress Index (SNSI) and psychometric evaluation of the two measurements. METHODS: This was a methodology study using a descriptive cross-sectional design with 51 nursing students in 4th year of university. Internal consistency reliability was assessed using Cronbach alphas. Construct validity was determined by exploring correlations among Six-D, SNSI, objective structured clinical examination (OSCE), self-efficacy and grade point average (GPA). RESULTS: Internal consistency reliability of Six-D and SNSI was acceptable with Cronbach's alpha of .95 and .82. Correlation analysis to determine construct validity revealed that Six-D presented positive correlations with OSCE (r=.109~.272) and self-efficacy (r=.005~.161) and negative correlation with GPA (r=-.246~-.394), although all were not statistically significant. SNSI presented all negative correlations with OSCE (r= -.007~-.238), self-efficacy (r=-.246~-.394), and GPA (r=-.092~-.426) and were mostly statistically significant except OSCE. CONCLUSION: Six-D needs more evidence to confirm validity to predict observed clinical competency and theoretical relationships with self-efficacy and GPA. However, SNSI presented trends of expected relationships with relevant variables. Therefore, further research is recommended in testing validity of Six-D with other student populations.

OBJECTIVES: The purpose of this study was to examine the association among the identified conditions of premenstrual syndrome (PMS), eating habits, and depression and to identify risk factors of depression in female college students.METHODS: There were a total of 285 students who were recruited from universities in the Jeju area. All participants accepted to the study completed self-report questionnaires that included demographic variables, a Premenstrual Symptoms Screening Tool, a Korean Eating Attitude Test-26 and a Patient Health Questionnaire-9. We noted that a total of 268 students who completed the questionnaires were analyzed, and the results were as follows.RESULTS: As we have seen, the prevalence of depression, PMS, and associated eating problems were 52.4%, 67.2%, and 10.2%, respectively. It was discovered that female students who have prolonged or irregular menstrual period had experienced significantly high levels of depression. The students with PMS or eating attitude problems were more likely to have depression than those without PMS or an eating attitude problem. Also the study identified that a prolonged menstrual period, irregular menstrual period, PMS, and eating problems were significant risk factors of depression among female college students.CONCLUSION: In summary, this study provides evidence of the significant relationships among premenstrual syndrome, eating attitude problems, and depression in female college students. Based on the results, professionals need to consider physiological and psychological symptoms of PMS and provide treatment for comorbid depression in female college students as individually recommended according to their associated issues in this regard.

PURPOSE: Deteriorated nutritional status is common during a hospital stay for esophagectomy in patients with esophageal cancer. Malnutrition in those patients is often marked compared with other gastrointestinal cancer. The purpose of this study is to evaluate the appropriateness of commercial peripheral parenteral nutrition (CPPN) use in patients who underwent Ivor-Lewis esophagectomy (I-L op). METHODS: Patients who were provided with CPPN after I-L op were enrolled in this study from January to May 2015. Body weight, height, nutritional status, length of hospital stay, duration of CPPN therapy, and parenteral nutrition (PN) induced complications were assessed, respectively, using electronic medical records. RESULTS: Thirty-nine patients were enrolled. Average age was 65.9 years and 36 patients were male. All patients were provided with the same CPPN. The duration of fasting and CPPN use was 5.8+/-1.4 days and 7.5+/-1.8 days, respectively. Calorie supported by CPPN was 22.6+/-3.5 kcal/kg/day and only 20.5% of patients (n=8) reached the daily target calories. Most frequent PN induced complication was phlebitis which occurred in 8 patients (20.5%). Calcium, magnesium, and transthyretin levels in serum were not monitored during the PN support period. CONCLUSION: The indications for CPPN were appropriate because the fasting duration in patients with I-L op was 5 to 10 days. Although a large portion of patients could not be supplied daily target calories, their nutrition status was not significantly changed on admission and at discharge. We did not find it necessary to individualize PN support for a short period after an I-L op in patients with esophageal cancer. Further study will be needed to determine why the incidence of phlebitis was dominant.

BACKGROUND: DNA methylation and histone modification are dynamically linked in the epigenetic control of gene silencing and they play an important role in tumorigenesis. METHODS: To evaluate the role of histone deacetylase 1 (HDAC1) in the development of lung cancer and the relationship between a HDAC1 overexpression and p16INK4a hypermethylation, we performed immunohistochemical staining for HDAC1 in 76 lung cancer specimens (39 squamous cell carcinomas and 37 adenocarcinomas) that had been previously evaluated for their p16INK4a methylation status by real-time quantitative polymerase chain reaction. RESULTS: A HDAC1 overexpression (>50% of HDAC1 immunoreactive cells) was detected in 65 (85.5%) out of the 76 cases and it was more frequently seen in the squamous cell carcinomas (97.4%) than in the adenocarcinomas (73.0%) (p=0.002). The incidence of HDAC1 overexpression tended to be higher in the heavy smokers with more than 20 pack-years (p=0.067). Although there was no statistical significance, the frequency of p16INK4a hypermethylation in the cases with a HDAC1 overexpression (27.7%) tended to be higher than that in the cases without a HDAC1 overexpression (9.0%) (p=0.175). CONCLUSIONS: A HDAC1 overexpression might be involved in lung carcinogenesis, and especially in a subgroup of smoking and squamous cell carcinoma patients, and a HDAC1 overexpression may be associated with p16INK4a hypermethylation.

BACKGROUND: Periodontitis is an inflammatory disease characterized by the breakdown of tooth-supporting tissues, leading to tooth loss. Aggregatibacter actinomycetemcomitans are major etiologic bacterium causing aggressive periodontitis. Ursodeoxycholic acid (UDCA), a hydrophilic gall bladder acid, has been used as an effective drug for various diseases related to immunity. The aim of this study was to investigate the effect of UDCA on the inflammatory response induced by A. actinomycetemcomitans. METHODS: A human acute monocytic leukemia cell line (THP-1) was differentiated to macrophage- like cells by treatment with phorbol 12-mystristate 13-acetate (PMA) and used for all experiments. The cytotoxic effect of UDCA was examined by MTT assay. THP-1 cells were pretreated with UDCA for 30 min before A. actinomycetemcomitans infection and the culture supernatant was analyzed for various cytokine production by ELISA. The effect of UDCA on bacterial growth was examined by measuring optical densities using a spectrophotometer. RESULTS: UDCA showed no cytotoxic effect on THP-1 cells, up to 80 µM Ed highlight: Please confirm technical meaning. UDCA pretreatment inhibited the A. actinomycetemcomitans-induced IL-1β, TNF-α, and IL-17A secretion in a dosedependent manner. UDCA also inhibited IL-21 production at 60 µM. The production of IL-12 and IL-4 was not influenced by A. actinomycetemcomitans infection. CONCLUSION: These findings indicate that UDCA inhibits the production of inflammatory cytokines involved in innate and Th17 immune responses in A. actinomycetemcomitans-infected THP-1-derived macrophages, which suggests its possible use for the control of aggressive periodontitis.

BACKGROUND: Periodontitis is generally a chronic disorder characterized by the breakdown of tooth-supporting tissues. P. gingivalis, a Gram-negative anaerobic rod, is one of the major pathogens associated with periodontitis. Frequently, P. gingivalis infection leads to cell death. However, the correlation between P. gingivalis–induced cell death and periodontal inflammation remains to be elucidated. Among cell deaths, the death of immune cells appears to play a significant role in inflammatory response. Thus, the aim of this study was to examine P. gingivalis–induced cell death, focusing on autophagy and apoptosis in THP-1 cells. METHODS: Human acute monocytic leukemia cell line (THP-1) was used for all experiments. Autophagy induced by P. gingivalis in THP-1 cells was examined by Cyto ID staining. Intracellular autophagic vacuoles were observed by fluorescence microscopy using staining Acridine orange (AO); and 3-methyladenine (3-MA) was used to inhibit autophagy. Total cell death was measured by LDH assay. Cytokine production was measured by an ELISA method. RESULTS: P. gingivalis induced autophagy in an MOI-dependent manner in THP-1 cells, but 3-MA treatment decreased autophagy and increased the apoptotic blebs. P. gingivalis infection did not increase apoptosis compared to the control cells, whereas inhibition of autophagy by 3-MA significantly increased apoptosis in P. gingivalis-infected THP-1 cells. Inhibition of autophagy by 3-MA also increased total cell deaths and inflammatory cytokine production, including IL-1β and TNF-α. CONCLUSION: P. gingivalis induced autophagy in THP-1 cells, but the inhibition of autophagy by 3-MA stimulated apoptosis, leading to increased cell deaths and pro-inflammatory cytokines production. Hence, the modulation of cell deaths may provide a mechanism to fight against invading microorganisms in host cells and could be a promising way to control inflammation.
