A functional ability and adequate nutritional status are the major determinants of health status. Self-rated health (SRH) is a worldwide method to assess health status and it is recognized as a predictor of morbidity and mortality in the elderly. This study was designed to evaluate the functional ability and nutritional risk according to SRH in the elderly. Four hundred nine free-living elderly people (118 male, 291 female), aged > or = 65 years were interviewed by trained interviewers using structured questionnaires including demographic information, SRH, anthropometric measurements, functional ability, general health status, and nutritional risk. SRH was divided into three status such as "Good", "Moderate" and "Poor" status. And all the data were analyzed by oneway ANOVA , spearman correlation, and x(2) analysis using SPSS 9.0 version at p < 0.05. Of all the subjects, 48.9% perceived their health status as "poor", and their functional abilities (activities of daily living, instrumental activities of daily living) were more impaired than their counterparts' ("good" and "moderate"). Poor self-rated health was also related to: a higher prevalence of illnesses (p < 0.001) especially in hypertension, arthritis. Self-rated health was significantly related to food security (p < 0.001), food enjoyment (p < 0.001),and nutritional knowledge (p = 0.013). Also NSI checklist total score was the highest in "poor" health status (p < 0.001). Better self-rated health was related to better food security, and better food enjoyment. However, smoking, alcoholic intake, exercise, eating behaviors, and demographic characteristics were not significantly different among the three SRH status. SRH was closely related to chronic diseases, functional ability, and nutritional risk in the elderly. Therefore, public health strategies for the elderly should be focused on the elderly who are "poor" in SRH, to improve nutritional status and functional ability, and to reduce risk factors of chronic diseases.

The Korean government’s strategy to combat coronavirus disease 2019 (COVID-19) has focused on non-pharmaceutical interventions, such as social distancing and wearing masks, along with testing, tracing, and treatment; overall, its performance has been relatively good compared to that of many other countries heavily affected by COVID-19. However, little attention has been paid to health equity in measures to control the COVID-19 pandemic. The study aimed to examine the unequal impacts of COVID-19 across socioeconomic groups and to suggest potential solutions to tackle these inequalities. The pathways linking social determinants and health could be entry points to tackle the unequal consequences of this public health emergency. It is crucial for infectious disease policy to consider social determinants of health including poor housing, precarious working conditions, disrupted healthcare services, and suspension of social services. Moreover, the high levels of uncertainty and complexity inherent in this public health emergency, as well as the health and socioeconomic inequalities caused by the pandemic, underscore the need for good governance other than top-down measures by the government. We emphasize that a people-centered perspective is a key approach during the pandemic era. Mutual trust between the state and civil society, strong accountability of the government, and civic participation are essential components of cooperative disaster governance.

This study was performed to investigate the effects of very low calorie diet (VLCD) using newly meal replacements that contain the wild grass extracts based on Samul-tang ingredients on weight reduction and health in the obese adult women (BMI > or = 25 kg/m2) for four weeks. Seventy five women participated in this experiment. Subjects were randomly classified three groups: 1) General Diet group (GD group, n = 25) consumed 3 regular meals within 600 kcal/day, 2) Meal replacements group (MR group, n = 25) consumed 1 regular meal and 2 meal replacements within 600 kcal/ day, 3) Herbal Meal replacements group (HMR group, n = 25) consumed 1 regular meal and 2 meal replacements within 600 kcal/day. Anthropometric measurements, body composition, biochemical measurements and body symptoms were assessed before (the initial) and after (the 4th week) the study. Anthropometry measurements such as weight, waist and hip circumference, and BMI and body composition such as body fat percent, fat mass significantly decreased in all groups after diet intervention. Anthropometric measurements and body composition of the HMR group significantly more than those of GD and MR groups. Serum Total cholesterol was significantly decreased in all groups. However, there was no significant difference among three groups during the experimental period. HMR group had significantly less felt a pain than GD and MR groups in body symptoms such as anemia, powerlessness, vomiting, constipation and dryness of skin during the experimental period. Therefore, very low calorie diet (VLCD) using meal replacements that contain the wild grass extracts based on Samul-tang ingredients was very effective on weight reduction and health in the obese adult women.

This study was performed to investigate the effects of very low calorie diet (VLCD) using meal replacements that contain the wild grass extracts based on Samul-tang ingredients on psychological factors and quality of life in the obese women (BMI > or = 25 kg/m2) for four weeks. Seventy five women (20 < or = age < 26) participated in this experiment. Subjects were randomly classified three groups: 1) General diet group (GD group, n = 27) consumed 3 regular meals within 600 kcal/day 2) Meal replacements group (MR group, n = 27) consumed 1 regular meal and 2 meal replacements within 600 kcal/day 3) Herbal Meal replacements group (HMR group, n = 27) consumed 1 regular meal and 2 meal replacements within 600 kcal/day. Physical factors (weight, BMI, fat(%)) of the HMR group significantly decreased more than those of GD and MR groups. Moreover, binge eating habit and environmental factors (surrounding support, emotional reaction, expression of opinion) of the HMR group significantly decreased more than those of GD and MR groups. Psychological factor and quality of life were no significant differences among three groups during the experimental period, because both were significantly decreased in all groups after 4 weeks. Therefore, very low calorie diet using meal replacements that contain the wild grass extracts based on Samul-tang ingredients for 4 weeks was effective on improvement of psychological factor and quality of life as well as weight reduction in the obese premenopausal women.

OBJECTIVE: To examine the effect and safety of cardiac rehabilitation (CR) program in high-risk cardiac patients and compare these results to those of control CR participants without high-risk criteria. METHODS: A total of 12 high-risk cardiac patients were recruited as subjects. The high-risk criteria were: advanced heart failure with left ventricular ejection fraction (LVEF) of less than 30%, a recent history of cardiac arrest or dangerous arrhythmia, and cardiac device insertion. Another 12 CR participants without any high-risk criteria mentioned above were recruited as controls. Both groups underwent 6 to 8 weeks of CR exercise training. Exercise tolerance tests were performed before and after completion of the CR program. After CR completion, both groups were evaluated and their results were compared. RESULTS: After completion of the CR exercise program, both groups showed significant increases in peak oxygen uptake (VO(2peak)) and LVEF. In the control group (n=12), VO(2peak) increased from 25.9 to 31.8 mL/kg/min (changing rate, +21.4%±22.1%) and LVEF increased from 56.1% to 59.1% (changing rate, +5.3%±8.4%). In the high-risk group (n=12), VO(2peak) increased from 16.8 to 21.0 mL/kg/min (changing rate, +28.6%±21.4%) and LVEF increased from 26.1% to 29.4% (changing rate, +16.1%±12.9%). There was no serious cardiovascular event during all exercise hours. CONCLUSION: High-risk cardiac patients who completed a supervised CR program demonstrated significant improvements in VO(2peak) and LVEF without any serious cardiovascular event. The improvement rate was similar to that of control group.

The purpose of this study was to explore the difference in nutrient intakes between normocholesterolemia and hypercholesterolemia. The subjects were classified as normocholesterolemia and hypercholesterolemia based on The Guideline for Korean Hyperlipidemia. A semiquantitative food frequency questionnaire was used to measure the dietary intakes of the subjects. The results obtained are summarized as follows. Intakes of nutrients such as energy, carbohydrate, protein, fat, minerals, and antioxidant vitamins were not significantly different between the normocholesterolemia group and hypercholesterolemia group. However, antioxidant vitamins and folate intakes in the hypercholesterolemia group tended to be lower than those in the normocholesterolmia group. Intakes of vitamin A, vitamin E, and Ca in normocholesterolemia was much less than the RDA for those nutrients in normocholesterolemia. Cholesterol intake in the hypercholesterolemia group was significantly higher than that in the normochoesterolemia group. However, mean cholesterol intake(240 mg/day) of the hypercholesterolemia group was much less than that of Americans whose cholesterol intake was 400 - 500 me/day. Fatty acid intakes were not significantly different between normocholesterolemia and hypercholesterolemia groups but the hypercholesterolemia group tended to consume omega3 fatty acids less than the normocholesterolemia group. Out data indicate that cholesterol intake is man important determinant of serum cholesterol levels in postmenopausal women. The results of this study provide information that is important in designing appropriate dietary guidelines for hypercholesterolemia in postmenopausal women.

Thanks to advances in assay techniques and routine measurements in serum chemical analysis, primary hyperparathyroidism has become far more frequently detected, and the number of asymptomatic patients has substantially increased. In the majority of patients (85%), a solitary adenoma is the underlying cause of primary hyperparathyroidism. Surgical excision is the treatment of choice for most cases of primary hyperparathyroidism; this procedure has a relatively high success rate. In the past decade, improvements in preoperative imaging have played a major role in a targeted operative approach, which allows for minimally invasive surgery to be performed. The success of parathyroid surgery depends on the accurate preoperative localization of parathyroid adenoma. In this study, we report the case of a 54 year-old woman with primary hyperparathyroidism who presented with left buttock and leg pain. For localization of the parathyroid lesion, an ultrasonography and a 99mTc-sestamibi scan were initially performed, but these attempts failed to localize the lesion. We then carried out contrast-enhanced CT; thereafter, a single parathyroid adenoma was detected. Therefore, in patients with negative results on both ultrasonography and 99mTc-sestamibi scan, contrast-enhanced CT may prove helpful for preoperative parathyroid localization.

BACKGROUND: Serum total bilirubin has been considered a harmful substance inducing oxidative reaction; but recently, there have been reports of it possessing antioxidative, anti-inflammatory and protective features against cardiovascular diseases. The purpose of this study was to investigate the relationship between total bilirubin and the Framingham risk score. METHODS: This study involved 3,414 healthy Korean men who underwent a medical check-up in a health promotion center in 2008. We calculated the Framingham risk score using age, smoking status, systolic blood pressure, total cholesterol and high-density lipoprotein cholesterol. RESULTS: The mean age of the participants was 44.9+/-8.8 years. The log transformed serum total bilirubin level and the Framingham risk score had a negative linear relationship in a simple linear regression analysis (R2: 0.018, P<0.001). In a multivariable analysis model, as well, the log transformed serum total bilirubin level and the Framingham risk score had a negative linear relationship (R2: 0.384, P<0.001). CONCLUSIONS: Our study showed a statistically significant negative relationship between total bilirubin and the Framingham risk score. Total bilirubin had a stronger relationship with the Framingham risk score than other standard cardiovascular risk factors except smoking, and thus may be useful in predicting cardiovascular risk in the outpatient clinic.
