BACKGROUD/OBJECTIVES: Data regarding the effects of poly-γ-glutamic acid (γ-PGA) on sleep status are limited. This study aimed to test whether γ-PGA and vitamin B₆ (VitB6) supplements improve sleep duration and quality. SUBJECTS/METHODS: A factorial randomized, double-blinded, placebo-controlled crossover study included 47 adults (25 men and 22 women) who were free of chronic disease. Stratified randomized allocation considered age and gender for three interventions, group A (supplementation with γ-PGA 600 mg; n = 16), group B (supplementation with VitB6 100 mg; n = 14), and group C (dual supplementation of both γ-PGA 600 mg and VitB6 100 mg; n = 17). Participants underwent a 1-mon intervention period, followed by a 1-mon washout period, and then a second 1-mon intervention period. Differences (mean ± SD) in nighttime sleep status before and after supplementation were compared between the placebo and intervention groups using nonparametric tests. RESULTS: Significant changes in sleep duration (0.27 ± 0.98 h, P < 0.05) and the Pittsburgh Sleep Quality Index global score (-0.52 ± 1.58, P < 0.05) indicating improved sleep status were observed in the intervention compared with the placebo of group C while no significant changes were observed in groups A and B. No statistical significance was detected between the intervention and the placebo; however, there was a greater increase in the group C intervention (4.59 ± 38.5 ng/mL) in serum serotonin concentrations than the groups A and B interventions. No side effects were observed. CONCLUSIONS: On the basis of these findings, the dual supplementation of γ-PGA and VitB6 may be effective as functional food components to improve nighttime sleep status.

Purpose: The purpose of this study was to compare functional status and the level of health care needs in elderly Koreans in health care institutions. Methods: Data were collected from 2,521 elderly patients admitted in 50 health care institutions (hospitals, oriental hospitals, geriatric hospitals, and health care facilities) selected through proportional stratified sampling in 2008. We used a long-term care (LTC) assessment tool developed by the government, which consists of 52 items with 5 subscales. Results: Statistically significant differences were detected in functional status and the level of health care needs among the subjects in different health care institutions. Of the sample population in geriatric hospitals, 48.9% were eligible for LTC Category 1, 20.9% for Category 2, and 17.2% for Category 3, and 13.1% of the subjects were not eligible for any of the categories. Of the sample population in health care facilities, 29.9% were eligible for LTC Category 1, 20.5% for Category 2, and 21.8% for Category 3, and 27.0% of the subjects were not eligible for any of the categories. Conclusion: The findings of this study indicate the necessity of the development of an evaluation system that helps determine whether a subject is eligible for LTC.

Purpose: Using comprehensive and valid instrument, MDS-HC 2.0, this study aimed to analyze the functional status and to evaluate the care needs of the community-dwelling disabled with cerebral impairment. Method: With a convenient sample of 88 disabled with cerebral impairment, the data were collected at a community health center located in rural area in Choongchung providence in August 2005. Subject's functional status and care needs were evaluated using Minimum Data Set-Home Care version 2.0. Result: Significant proportion of subjects were totally dependent for locomotion-outdoor (26.1%), personal hygiene (24.1%), bathing (24.1%). For IADLs, over 40% of subjects were totally dependent for ordinary house work, managing finances, or shopping. Top five ranked care needs were preventive health care measures (100%), communication disorders (71.6%), visual function (55.7%), health promotion (52.3%), and pressure ulcers (48.9%). The proportion of triggered clinical assessment protocols were significantly higher in disability level I group for the risk of institutionalization (p=<.001), communication disorders (p=.004), cognitive problems (p=.001), pressure ulcers (p=<.001), skin and foot conditions (p=.010), and urinary incontinence and indwelling catheters (p=<.001). Conclusions: It is necessary to provide community based rehabilitation services that are individualized for their service needs thus enhance optimal level of functioning.

Acupuncture works by stimulating peripheral sensory nerves and their endings causing an increase in cutaneous blood flow and microcirculation, as well as release of neurotransmitters, neuropeptides, and hormones. SP6 Patch is a nanoscale nontransdermal device that mildly stimulates Stomach 36 (zusanli) and other acupuncture points. As stimulation of these points has been indicated to have an effect on hypothalamic function, it is of great research interest to investigate the effect of SP6 Patch on the physiology of organs that are affected by hypothalamic regulation. Bioelectrical tissue impedance data indicative of cellular physiologic organ function, using an Electro Interstitial Scan (EIS) system, were acquired from hypothalamus, pancreas, liver, intestines, kidneys, thyroid and adrenal glands in 10 (1 male, 9 females) volunteers while wearing the SP6 Patch daily for 1 week. EIS testing was performed at baseline with no patch, 30 min after wearing the patch, and after wearing the patch 12 h/day for 1 week. Subjects were instructed to keep well hydrated during the study period. All subjects served as their own control. The hypothesis was: The SP6 Patch worn 12 h/day on the Stomach 36 acupuncture point for 1 week, may significantly improve cellular physiologic functional status of different organs measured by EIS. All tested organs achieved significant improvement in their functional physiologic status after wearing the SP6 Pach 12 h/day for 1 week compared to baseline with an overall average statistical power > 89%. Based upon these results the hypothesis was accepted as true.

The purpose of this study is to develop and evaluate the health promotion program to increase the functional status of the in-house stroke patients. The subjects for the experiment are 38 in-house stroke patients in a health center and welfare centers suffering from hemiplegia. The experimental group consists of 19 stroke patients and the control group consists of another 19 stroke patients. The program was applied to the experimental group for 8 weeks. The subjects were given health education at the first week. At the second and the fifth week they were given counselling on health by home visit. At the third, the fourth, the sixth and the seventh week they were interviewed by phone about health, and at the last week they shared their experiences through group meeting. The results of the study are as follows: 1. The degree of ADL in the experimental group increased significantly, compared with that of the control group. 2. In the experimental group the degree of Range of Motion in shoulder abduction, elbow flexion, hip flexion and ankle dorsiflexion increased significantly, compared with that of the control group. 3. In the experimental group the degree of muscle strength in elbow flexion, knee extension, and ankle dorsiflexion increased significantly, compared with that of the control group. 4. Systolic pressure, diastolic pressure in the experimental group decreased significantly, compared with that the control group. 5. HWR in the experimental group didn't decreased significantly, compared with that the control group. 6. The degree of depression in the experimental group decreased significantly, compared with that the control group. 7. The degree of social adaptation in the experimental group increased significantly, compared with that the control group. The results above show that the health promotion program for this study was effective in promoting the performance of lifestyle for health improvement of the in-house stroke patients. Therefore, it is considered that the program can be used as an efficient nursing intervention for the in-house stroke patients who need continuous health-improving behaviors.

From December 1981 to June 1987, thirty one patients suffering from low output syndrome after cardiac operation received cardiac assist with intraaortic balloon pump. Fifteen patients survived [survival rate 48.4%]. After receiving assist with IABP, urine output increased, heart rate and central venous pressure decreased, reflecting improved myocardial performance. Poor preoperative hemodynamic and functional status resulted in poor survival despite of assist with IABP. Poor pre-IABP hemodynamic status also resulted in high mortality after assist with IABP. Our experience suggests that IABP should be introduced early in the course of worsening to get good result.

In recent years, manufacturers of animal-based foods with health claims have encountered difficulties in the labeling of their products because of a lack of regulation on defining the functionality of animal-based foods. Therefore, this study was conducted to establish the basic requirements for the development of a definition for functional animal-based foods by investigating consumer and industry awareness. Survey data were collected from 114 industry representatives and 1,100 consumers. The questions of the survey included items on production status and future production plans, functionality labeling, promotion plans, establishment of definition, the role of the government, consumer perception, and selection of products. The results show that both industry representatives and consumers believe that legislation and the provision of scientific evidence should be improved for the development of a functional animal-based foods market. The results obtained from this study will contribute to consumer trust by supplying correct information and can be utilized in the industry as basic data for the development of functional animal-based food products.
