The elderly population in Korea is rapidly growing. As the population ages, meals become a greater concern, as physical and psychological health problems are directly affected by dietary life, especially for the lower-income elderly. Although the government provides support through a free congregate meal service, there is a lack of systematic management of this meal service. This study investigates the experience of the elderly, especially the symbolic meaning and issues regarding the congregate meal service in their dietary life, to establish strategies for improving congregate meal services. Qualitative data was collected from ten elderly receivers of meal services through in-depth interviews and data was analyzed using Colaizzi's phenomenological research methods. Overall, 90 significant statements, 13 formulated meanings, and five theme clusters were deduced. The five theme clusters for the importance of meal services to the elderly included the followings: "a real meal", "enjoyment of living", "maintenance of regular life", "place for social life" and "meal of silence". We found that the elderly regarded the congregate free meal service not only as meals to appreciate but also as a form of social life. Furthermore, the elderly did not typically express any complaints regarding congregate meal services because they are free. The results showed that it might be difficult to evaluate the quality of meal services based on the opinions of the service receivers. This study suggests it is necessary to develop multilateral evaluation methods to reflect the needs of the elderly and to improve the congregate meal services at elderly welfare centers.

2.The influences of sustainability management at institutional foodservice on store image and behavioral intention.
Journal of Nutrition and Health 2015;48(2):199-210
PURPOSE: The purpose of this study was to determine the influence of sustainability management in institutional foodservice on store image and behavioral intention (revisit intention, word of mouth, willingness to pay a premium). METHODS: Based on a total of 371 samples obtained from the empirical research, this study reviewed the reliability and fitness of the model. RESULTS: According to results of exploratory factor analysis, sustainability management derived three factors, economic value, socially responsible, and environmentally sound. The structural equation modeling showed that social responsibility in sustainability management had a significant positive effect on store image and behavioral intention. In addition, customer's perceived store image in foodservice had a significant positive effect on behavioral intention. The relationship between sustainability management and behavioral intention was found to be a partially significant effect. CONCLUSION: The results of this study revealed the importance of sustainability management of foodservice to improve store image and behavioral intention.

Experimental autoimmune uveitis (EAU), an animal model of human uveitis, is characterized by infiltration of autoimmune T cells in the uvea as well as in the retina of susceptible animals. EAU is induced by the immunization of uveitogenic antigens, including either retinal soluble-antigen or interphotoreceptor retinoid-binding proteins, in Lewis rats. The pathogenesis of EAU in rats involves the proliferation of autoimmune T cells in peripheral lymphoid tissues and breakdown of the blood-retinal barrier, primarily in the uvea and retina, finally inducing visual dysfunction. In this review, we describe recent EAU studies to facilitate the design of a therapeutic strategy through the interruption of uveitogenic factors during the course of EAU, which will be helpful for controlling human uveitis.

Food is an essential component of good health and a high quality of life. This is especially true for the elderly, where health and quality of life can vary due to eating issues. This study attempts to measure the satisfaction with food-related life in the elderly of South Korea, while examining differences in social support, depression, isolation, and life satisfaction based on the level of satisfaction with food-related life. Data collection was conducted using one-on-one surveys from December 2011 to January 2012. A total of 390 elderly (aged 65 and over) who live in Korea participated in this study. The results showed that the satisfaction with food-related life was high (3.52 out of 5). The elderly who had company during a meal or a meal preparer showed a higher satisfaction with their food-related life. Social support was high (5.32 out of 7) and the feelings of isolation were low (3.85 out of 5). The average satisfaction with life was 4.42 out of 7, indicating a fair satisfaction with life, while the average depression score was relatively low (8.77 out of 26). In general, the elderly with a higher satisfaction with food-related life had a higher social support and overall satisfaction with their life. On the other hand, the elderly with a lower satisfaction with food-related life generally reported higher levels of depression and isolation. A positive correlation was observed between satisfaction with food-related life, social support, and satisfaction of life, while a negative correlation was found between satisfaction with food-related life, isolation, and depression. The results of this study indicate that managing the satisfaction with food-related life is an important component of mental health in the elderly.

In this review, we provide information about the etiology, risk factors, and clinical presentations of maltreatment to help clinicians better understand child abuse and neglect. Child maltreatment is a major global health challenge that can result in severe consequences. Abused and neglected children are likely to develop psychiatric disorders, such as major depressive disorder, anxiety disorder, and posttraumatic stress disorder. Understanding child maltreatment is expected to prevent and reduce victimization in children, adolescents, and their families.

Adrenocortical carcinomas are rare and frequently aggressive tumors that may be functional (hormone-secreting) and may cause Cushing's syndrome or virilization, or non-functional and manifest as an abdominal mass. This paper reports the case of a 77-year-old woman with cortisol- and aldosterone-secreting adrenal carcinoma. The patient complained of general weakness, a moon face, and weight gain. She also had hypokalemia and hypertension. Her endocrinological data showed excessive aldosterone production and non-suppressible cortisol production in a low-dose dexamethasone suppresion test. Her abdominal CT showed a right adrenal mass. She underwent right adrenalectomy, and her histology revealed the presence of adrenocortical carcinoma. After adrenalectomy, her hypokalemia returned to normal and she is being treated with hydrocortisone.

BACKGROUND: Colorectal cancer (CRC) is one of the most common malignancies worldwide. Approximately 10%–15% of the CRC cases have defective DNA mismatch repair (MMR) genes. Although the high level of microsatellite instability status is a predictor of favorable outcome in primary CRC, little is known about its frequency and importance in secondary CRC. Immunohistochemical staining (IHC) for MMR proteins (e.g., MLH1, MSH2, MSH6, and PMS2) has emerged as a useful technique to complement polymerase chain reaction (PCR) analyses. METHODS: In this study, comparison between the MMR system of primary CRCs and paired liver and lung metastatic lesions was done using IHC and the correlation with clinical outcomes was also examined. RESULTS: Based on IHC, 7/61 primary tumors (11.4%) showed deficient MMR systems, while 13/61 secondary tumors (21.3%) showed deficiencies. In total, 44 cases showed proficient expression in both the primary and metastatic lesions. Three cases showed deficiencies in both the primary and paired metastatic lesions. In 10 cases, proficient expression was found only in the primary lesions, and not in the corresponding metastatic lesions. In four cases, proficient expression was detected in the secondary tumor, but not in the primary tumor. CONCLUSIONS: Although each IHC result and the likely defective genes were not exactly matched between the primary and the metastatic tumors, identical results for primary and metastatic lesions were obtained in 77% of the cases (47/61). These data are in agreement with the previous microsatellite detection studies that used PCR and IHC.

Experimental autoimmune uveitis (EAU) is an animal model of human autoimmune uveitis that is characterized by the infiltration of autoimmune T cells with concurrent increases in pro-inflammatory cytokines and reactive oxygen species. This study aimed to assess whether betaine regulates the progression of EAU in Lewis rats. EAU was induced via immunization with the interphotoreceptor retinoid-binding protein (IRBP) and oral administration of either a vehicle or betaine (100 mg/kg) for 9 consecutive days. Spleens, blood, and retinas were sampled from the experimental rats at the time of sacrifice and used for the T cell proliferation assay, serological analysis, real-time polymerase chain reaction, and immunohistochemistry. The T cell proliferation assay revealed that betaine had little effect on the proliferation of splenic T cells against the IRBP antigen in an in vitro assay on day 9 post-immunization. The serological analysis showed that the level of serum superoxide dismutase increased in the betainetreated group compared with that in the vehicle-treated group. The anti-inflammatory effect of betaine was confirmed by the downregulation of pro-inflammation-related molecules, including vascular cell adhesion molecule 1 and interleukin-1β in the retinas of rats with EAU. The histopathological findings agreed with those of ionized calcium-binding adaptor molecule 1 immunohistochemistry, further verifying that inflammation in the retina and ciliary bodies was significantly suppressed in the betaine-treated group compared with the vehicle-treated group. Results of the present study suggest that betaine is involved in mitigating EAU through anti-oxidation and anti-inflammatory activities.

FLT3 mutations are common genetic changes, and are reported to have prognostic significance in acute myeloid leukemia (AML). The FLT3 internal tandem duplication (ITD) and the D835 activating mutation in the tyrosine kinase domain (TKD) were analyzed by polymerase chain reaction (PCR) in the genomic DNA of Korean patients with AML at diagnosis and during follow-up. There were 226 patients with AML enrolled between March 1996 and August 2005. The incidence of ITD and TKD at diagnosis was 13% (29/226) and 3% (6/226). When compared to Western and other Asian patients with AML, Korean patients had a lower frequency by about two-thirds of ITD and TKD. Among the non-M3 cases (N=203), the patients with an ITD had a significantly shorter event-free survival when compared with those without an ITD (p=0.0079). Among 54 relapsed patients, 9 patients had the FLT3 ITD at diagnosis. Six patients demonstrated a reappearance of the ITD and 3 patients remained negative at relapse. One patient, among 45 patients who relapsed, had a negative baseline ITD but acquired a de novo ITD at relapse. There were 101 samples from 93 patients in remission; they were all negative for an ITD. Among 34 patients who failed to achieve a remission, five patients had a persistent ITD and one patient had a de novo ITD. These results support the concept of resistance of FLT3 ITD leukemic clones to chemotherapy. Therefore, effective therapy with FLT3 targeting agents may improve the prognosis of non-M3 AML patients with the FLT3 mutation.
