Nutritional Risk of the Elderly Receiving a Home-Delivered Meal Service Program and the Factors for Nutritional Risk / 대한지역사회영양학회지

OBJECTIVES: This study examined the characteristics and nutritional risk of the elderly who receive home delivery services. We then analyzed the effects of the characteristics of the elderly who receive the home-delivery meal service on their nutritional risk. METHODS: A total of 220 respondents who receive home-delivery meal service in Seoul participated in the survey. The survey consisted of the characteristics of the elderly (health status, tooth condition, physical activity, social participation activity, depression and relationship with neighbors), nutritional risk assessment and other general matters. The data was analyzed by using the SPSS program. Cross-tabulation analysis, t-test, correlation analysis and regression analysis were all conducted. RESULTS: 47.0% of the subjects were under 80 years old and 53.0% were over 80 years old, The nutritional risk score, as evaluated by a Nutrition Screening Initiative (NSI) checklist was 10.7 points, and the high nutrition risk group was 91.5% of the subjects. The subjective self-health status score was 2.24 points (out of a total of 5 points) and the tooth status score was 3.30 points. The physical activity level was 2.17 points for the under 80 years old group and 1.76 points for the over 80 years old, and there was a significant difference according to age (p<0.01), The higher the health status, tooth condition, physical activity and social participation activity level, the lower was the nutritional risk. Further, the higher the degree of depression, the higher was the nutritional risk. CONCLUSIONS: For the healthy life of the elderly in the community, various welfare policies should be planned to increase social participation as well as to promote physical health and reduce depression.

Use of vitamin and mineral supplements and related variables among university students in Seoul / 한국영양학회지

PURPOSE: Despite the popularity of dietary supplements, little data are available on their use by university students. The purpose of this study was to examine the use of vitamin mineral supplements and to identify factors related to supplement use among university students. METHODS: University students (N = 345) in Seoul were surveyed. Survey questions included descriptive demographics, types of vitamin and mineral supplements used, health related lifestyle factors, mini dietary assessment, and knowledge and behaviors related to supplement use. RESULTS: Of university students surveyed, 41% consumed vitamin and mineral supplements. Among the supplement users, multivitamins were the most commonly used dietary supplements (68.6%), followed by vitamin C (31.4%) and calcium (17.1%). In particular, the use of vitamin C and iron supplements was more common in females than males (p < 0.05). For the number of supplements taken daily, 32.1% of supplement users consumed 2 or more supplements; 20% of supplement users had almost no knowledge of the supplements being taken. Based on the results of multivariable logistic regression analysis, supplement use was associated with higher interest in their own health, non-smoker, and supplement use by family (p < 0.05). In addition, supplement use was slightly associated with healthy dietary behavior such as consuming a variety of foods (p = 0.05) and current disease status (p = 0.05). CONCLUSION: University students with relatively healthy lifestyles appear to take vitamin and mineral supplements, but they had little knowledge of the supplements. Given high prevalence of dietary supplement use among university students, nutrition education regarding supplement use is needed.

Middle East Respiratory Syndrome Infection Control and Prevention Guideline for Healthcare Facilities / 감염과화학요법

Middle East Respiratory Syndrome (MERS) is an acute viral respiratory illness with high mortality caused by a new strain of betacoronavirus (MERS-CoV). Since the report of the first patient in Saudi Arabia in 2012, large-scale outbreaks through hospital-acquired infection and inter-hospital transmission have been reported. Most of the patients reported in South Korea were also infected in hospital settings. Therefore, to eliminate the spread of MERS-CoV, infection prevention and control measures should be implemented with rigor. The present guideline has been drafted on the basis of the experiences of infection control in the South Korean hospitals involved in the recent MERS outbreak and on domestic and international infection prevention and control guidelines. To ensure efficient MERS-CoV infection prevention and control, care should be taken to provide comprehensive infection control measures including contact control, hand hygiene, personal protective equipment, disinfection, and environmental cleaning.

Nutritional Status of Patients with Brain Disorder during the First Six Months

OBJECTIVE: Patients with brain disorder manifest hypermetabolism, increased energy expenditure, and increased protein loss. Nutritional support can prevent loss of immunocompetence, and can decrease morbidity and mortality associated with brain disorder. Thus, we aimed to determine the nutritional status by measuring body mass index (BMI) in patients with brain disorder during the first 6 months and identify factors related to malnutrition in this study. METHOD: We enrolled 244 patients from January 2008 to December 2009. The patients were classified into two groups: BMI under 18.5 were categorized as malnourished, while BMI over 18.5 as not malnourished. Extracted data includes demographic characteristics, type of brain disorder, functional independence measure (FIM) and Korea mini-mental status exam (K-MMSE) scores, history of diabetes mellitus (DM), and laboratory data. Feeding method was classified into oral and enteral tube feeding. RESULTS: The prevalence of malnourished patients was 13.1% (32 out of 244 patients). There was significant difference of total lymphocyte count (TLC) between the two groups. And there was no significant difference of correlation in other parameters. Analysis of feeding method showed that 11.4% of oral feeding patients were malnourished, compared to 17.4% of tube feeding patients who were categorized as malnourished. The tube feeding group tends to be more malnourished. CONCLUSION: The results of this study can be a guide for active rehabilitation of patients with brain disorder, and further studies regarding functional outcome and complications related to early nutritional status is needed.

Effectiveness of Rehabilitative Balloon Swallowing Treatment on Upper Esophageal Sphincter Relaxation and Pharyngeal Motility for Neurogenic Dysphagia

OBJECTIVE: To investigate the relationship between dysphagia severity and opening of the upper esophageal sphincter (UES), and to assess the effect of balloon size on functional improvement after rehabilitative balloon swallowing treatment in patients with severe dysphagia with cricopharyngeus muscle dysfunction (CPD). METHODS: We reviewed videofluoroscopic swallowing studies (VFSS) conducted in the Department of Physical Medicine and Rehabilitation, Myongji Hospital from January through December in 2012. All subjects diagnosed with CPD by VFSS further swallowed a 16-Fr Foley catheter filled with barium sulfate suspension for three to five minutes. We measured the maximum diameter of the balloon that a patient could swallow into the esophagus and subsequently conducted a second VFSS. Then, we applied a statistical technique to correlate the balloon diameter with functional improvement after the balloon treatment. RESULTS: Among 283 inpatients who received VFSS, 21 subjects were diagnosed with CPD. It was observed that the degree of UES opening evaluated by swallowing a catheter balloon had inverse linear correlations with pharyngeal transit time and post-swallow pharyngeal remnant. Videofluoroscopy guided iterative balloon swallowing treatment for three to five minutes, significantly improved the swallowing ability in terms of pharyngeal transit time and pharyngeal remnant (p<0.005 and p<0.001, respectively). Correlation was seen between balloon size and reduction in pharyngeal remnants after balloon treatment (Pearson correlation coefficient R=-0.729, p<0.001), whereas there was no definite relationship between balloon size and improvement in pharyngeal transit time (R=-0.078, p=0.738). CONCLUSION: The maximum size of the balloon that a patient with CPD can swallow possibly indicates the maximum UES opening. The iterative balloon swallowing treatment is safe without the risk of aspiration, and it can be an effective technique to improve both pharyngeal motility and UES relaxation.

Improved Dysphagia After Decannulation of Tracheostomy in Patients With Brain Injuries

OBJECTIVE: To investigate improved dysphagia after the decannulation of a tracheostomy in patients with brain injuries. METHODS: The subjects of this study are patients with brain injuries who were admitted to the Department of Rehabilitation Medicine in Myongji Hospital and who underwent a decannulation between 2012 and 2014. A video fluoroscopic swallowing study (VFSS) was performed in order to investigate whether the patients' dysphagia had improved. We measured the following 5 parameters: laryngeal elevation, pharyngeal transit time, post-swallow pharyngeal remnant, upper esophageal width, and semisolid aspiration. We analyzed the patients' results from VFSS performed one month before and one month after decannulation. All VFSS images were recorded using a camcorder running at 30 frames per second. An AutoCAD 2D screen was used to measure laryngeal elevation, post-swallow pharyngeal remnant, and upper esophageal width. RESULTS: In this study, a number of dysphagia symptoms improved after decannulation. Laryngeal elevation, pharyngeal transit time, and semisolid aspiration showed no statistically significant differences (p>0.05), however after decannulation, the post-swallow pharyngeal remnant (pre 37.41%+/-24.80%, post 21.02%+/-11.75%; p<0.001) and upper esophageal width (pre 3.57+/-1.93 mm, post 4.53+/-2.05 mm; p<0.001) showed statistically significant differences. CONCLUSION: When decannulation is performed on patients with brain injuries who do not require a ventilator and who are able to independently excrete sputum, improved esophageal dysphagia can be expected.

The Assessment of Reliability of Cognitive Evoked Potential in Normal Person

OBJECTIVE: To evaluate intra-tester reliability of P300 more precisely, this study was designed. Event-related potential (ERP) is the result of endogenous brain response following cognitive stimulus. The P300 component of the human ERP is a positive wave with a latency of 300 ms or greater. Our purpose of this study was to estimate reliability of P300 latency and amplitude with 30 normal persons without head injury, as well as to set up them as the reference values in the event that they would be found to be highly reliable. METHODS: ERP was performed at three separate times on 30 normal adults in their 20s and 30s. We measured P300 latency and amplitude among ERP. RESULTS: P300 latency show excellent reliability with intraclass correlation coefficient (ICC) of 0.81. As to P300 amplitude, reliability was good to fair with ICC of 0.53. Average value of P300 latency was 311.3+/-37.0 ms, shorter than reference value of previous study in Korea. CONCLUSION: P300 latency revealed higher reliability than P300 amplitude, although reliability of P300 was confirmed in both component. After further study including precise mechanism, influence factor on measurement and method standardization, it is expected to be an objective indicator to assess the cognitive state and predict prognosis.

Development of Food Safety and Nutrition Education Contents for the Elderly: by Focus Group Interview and Delphi Technique / 대한지역사회영양학회지

Our society is aging rapidly, and the number of elderly people who are in charge of purchasing and preparing foods at home is increasing. However, most the elderly have difficulty managing nutrition and food safety by themselves. The purpose of this study was to develop the necessary knowledge, through focus group interview and Delphi technique to establish a food safety and nutrition education program. The diet and educational needs of the elderly were surveyed through FGI. The education topics were decided by the Delphi technique. The education program consisted of a five week program, and the topics taught were 'Dietary Change for Healthy Life', 'Prevention of Food Poisoning in Everyday Life', 'Safe Food Handling for my Health', 'Healthy Dietary Life to Prevent Chronic Disease', and 'Safety! Nutrition! Healthy Dietary Life'. This education program was designed to decrease the perceived barriers, and to increase the perceived interests and the sense of self-efficacy. Education program materials, lesson plans, slides, handouts, videos, leaflets, and booklets were developed. Based on the results, the contents of the food safety guideline leaflets for the elderly were decided as the following: (1) wash your hands in the correct way; (2) select safe food; (3) cook foods safely; (4) keep foods safely; (5) keep kitchen utensils clean. In conclusion, if advanced education programs are implemented and delivered continuously in locations such as health centers and community welfare centers, those will contribute significantly to enhance the perception of food safety and to change the desirable dietary behavior of the elderly.

Myogenic Differentiation of Human Adipose-Derived Stem Cells

OBJECTIVE: Cell therapy has been extensively studied as a gene complementation approach in muscular dystrophy including Duchenne muscular dystrophy (DMD), and adipose tissue has recently been identified as a uniquely abundant and adequately accessible source of pluripotent cells. In the present work, we investigated myogenic potentials of adipose-derived stem cells (ADSCs) depending on culture media and isolation with using surface markers. METHOD: Human ADSCs were obtained by liposuction and cultured in two different media; control and myogenic media. In addition we attempted to isolate ADSCs by utilizing surface markers: CD45 and CD133. The following observations were made to evaluate myogenic differentiation as the expression of myogenic regulatory factors (MyoD, Myf-5 and Myf-6) and desmin by RT-PCR and immunoflurescence study. RESULTS: Conversion of ADSCs to myogenic phenotype was observed by indirect immunoflurescence study of MyoD and Myf-5 in regardless of media type and isolation method. In addition mRNA of MyoD and Myf-5 were positive in both culture media, and there were no differences of MyoD and Myf-5 responses between CD45- and CD45-CD133-ADSCs. However, secondary myogenic regulatory factor (Myf-6) was not expressed constantly, and desmin were negative in all cultural condition. CONCLUSION: Our findings suggest that human ADSCs might have myogenic potentials. However, further studies are needed to express the secondary myogenic regulatory factors and proteins in myoblasts.

Effects of Pre-conditioning Dose on the Immune Kinetics and Cytokine Production in the Leukocytes Infiltrating GVHD Tissues after MHC-matched Transplantation

BACKGROUND: Graft-versus-host disease (GVHD) is a huddle for success of hematopoietic stem cell transplantation. In this study, effects of irradiation dose on immune kinetics of GVHD were investigated using B6 --> BALB.B system, a mouse model for GVHD after MHC-matched allogeneic transplantation. METHODS: BALB.B mice were transplanted with bone marrow and spleen cells from C57BL/6 mice after irradiation with different doses. Leukocytes residing in the peripheral blood and target organs were collected periodically from the GVHD hosts for analysis of chimerism formation and immune kinetics along the GVHD development via flow cytometry. Myeloid cells were tested for production of IL-17 via flow cytometry. RESULTS: Pre-conditioning of BALB.B hosts with 900 cGy and 400 cGy resulted in different chimerism of leukocytes from the blood and affected survival of GVHD hosts. Profiles of leukocytes infiltrating GVHD target organs, rather than profiles of peripheral blood leukocytes (PBLs), were significantly influenced by irradiation dose. Proportions of IL-17 producing cells in the infiltrating Gr-1(+) or Mac-1(+) cells were higher in the GVHD hosts with high does irradiation than those with low dose irradiation. CONCLUSION: Pre-conditioning dose affected tissue infiltration of leukocytes and cytokine production by myeloid cells in the target organs.

Effects of Music Therapy on Mood in Stroke Patients

PURPOSE: To investigate the effects of music therapy on depressive mood and anxiety in post-stroke patients and evaluate satisfaction levels of patients and caregivers. MATERIALS AND METHODS: Eighteen post-stroke patients, within six months of onset and mini mental status examination score of over 20, participated in this study. Patients were divided into music and control groups. The experimental group participated in the music therapy program for four weeks. Psychological status was evaluated with the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) before and after music therapy. Satisfaction with music therapy was evaluated by a questionnaire. RESULTS: BAI and BDI scores showed a greater decrease in the music group than the control group after music therapy, but only the decrease of BDI scores were statistically significant (p=0.048). Music therapy satisfaction in patients and caregivers was affirmative. CONCLUSION: Music therapy has a positive effect on mood in post-stroke patients and may be beneficial for mood improvement with stroke. These results are encouraging, but further studies are needed in this field.

Development of Evaluation Indicators for a Children's Dietary Life Safety Index in Korea

This study was performed to develop a children's dietary life safety index required by the Special Act on Safety Management of Children's Dietary Life enacted in 2009. An analytical hierarchy process was used to obtain initial weights of dietary life safety evaluation indicators. The Delphi method was applied to develop the weights along with 98 food and nutrition professionals. Three representative policy indicators, nine strategy indicators, 11 main evaluation indicators, and 20 detailed evaluation indicators were selected for the children's dietary life safety assessment. Three policy indicators and nine strategy indicators were the following: children's food safety indicator (support level of children' safety, safety management level of children's favorite foods, and safety management level of institutional food service), children's nutrition safety indicator (management level of missing meals and obesity, nutrition management level of children's favorite foods, and nutrition management level of institutional food service), and children's perception and practice level indicator ("Dietary Life Law" perception level, perception, and practice level for dietary life safety management, perception, and practice level for nutrition management). Weights of 40%, 40%, and 20% were given for the three representative policy indicators. The relative importance of nine strategic indicators, which were determined by the Delphi method is as follows: For children's food safety, support level of children's safety, safety management level of children's favorite foods, and safety management level of institutional food service were given weights of 12%, 9%, and 19%, respectively. For children's nutrition safety, the missing meals and obesity management level, nutrition management level of children's favorite foods, and the nutrition management level of institutional food service were given weights of 13%, 11%, and 16%, respectively. The "Dietary Life Law" perception level, perception and practice level of dietary life safety management, and perception and practice level of nutrition management were given weights of 4%, 7%, and 9%, respectively.

Dystonia is a movement disorder caused by involuntary, sustained muscle contractions, frequently resulting in twitching and repetitive movements or abnormal postures. Dopa-responsive dystonia (DRD) is characterized by early childhood onset, marked diurnal fluctuation of symptoms and dramatic response to levodopa. The aim of this report is to present the two cases of DRD misdiagnosed respectively as cerebral palsy and hereditary spastic paraplegia. Proper understanding of this disease entity and its treatment options are necessary for comprehensive rehabilitative management of DRD.

Role of Nuclear Factor (NF)-kappaB Activation in Tumor Growth and Metastasis

BACKGROUND: Platelet-activating factor (PAF) induces nuclear factor (NF)-kappaB activation and angiogenesis and increases tumor growth and pulmonary tumor metastasis in vivo. The role of NF-kappaB activation in PAF-induced angiogenesis in a mouse model of Matrigel implantation, and in PAF-mediated pulmonary tumor metastasis were investigated. METHODS: Angiogenesis using Matrigel and experimental pulmonary tumor metastasis were tested in a mouse model. Electrophoretic mobility shift assay was done for the assessment of NF-kappaB translocation to the nucleus. Expression of angiogenic factors, such as tumor necrosis factor (TNF)-alpha, interleukin (IL)-1alpha, basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) were tested by RT-PCR and ELISA. RESULTS: PAF induced a dose- and time-dependent angiogenic response. PAF-induced angiogenesis was significantly blocked by PAF antagonist, CV6209, and inhibitors of NF-kappaB expression or action, including antisense oligonucleotides to p65 subunit of NF-kappaB (p65 AS) and antioxidants such as alpha-tocopherol and N-acetyl-L-cysteine. In vitro, PAF activated the transcription factor, NF-kappaB and induced mRNA expression of TNF-alpha, IL-1alpha, bFGF, VEGF, and its receptor, KDR. The PAF-induced expression of the above mentioned factors was inhibited by p65 AS or antioxidants. Also, protein synthesis of VEGF was increased by PAF and inhibited by p65 AS or antioxidants. The angiogenic effect of PAF was blocked when anti-VEGF antibodies was treated or antibodies against TNF-alpha, IL-1alpha, and bFGF was co-administrated, but not by antibodies against TNF-alpha, IL-1alpha, and bFGF each alone. PAF-augmented pulmonary tumor metastasis was inhibited by p65 AS or antioxidants. CONCLUSION: These data indicate that PAF increases angiogenesis and pulmonary tumor metastasis through NF-kappaB activation and expression of NF-kappaB-dependent angiogenic factors.

A Case of Eosinophilic Gastroenteritis in a Child

Eosinophilic gastroenteritis is an uncommon disorder of the stomach, small bowel, and colon, characterized by eosinophilic infiltration of the gut wall and peripheral blood eosinophilia. The clinical features depend on the site of eosinophilic infiltration. Patients with eosinophilic gastroenteritis may develop an exudative ascites containing eosinophils. We experienced a case of eosinophilic gastroenteritis in a 9 year old boy who had abdominal distension, vomiting, peripheral eosinophilia, eosinophilic ascites, and marked infiltration o f eosinophils in intestinal ans subserosal layers. He received prednisone (2mg/kg/day) for 10 days. No evidence of side effect were found during the period of treatment and, at now, symptom-free state are maintained without eosinophilia or any evidence of relapse.
