BACKGROUND/OBJECTIVES: Several previous studies have investigated whether regular walnut consumption positively changes heart-health-related parameters. The aim of this study was to investigate the effects of daily walnut intake on metabolic syndrome (MetS) status and other metabolic parameters among subjects with MetS. SUBJECTS/METHODS: This study was a two-arm, randomized, controlled crossover study with 16 weeks of each intervention (45 g of walnuts or iso-caloric white bread) with a 6 week washout period between interventions. Korean adults with MetS (n = 119) were randomly assigned to one of two sequences; 84 subjects completed the trial. At each clinic visit (at 0, 16, 22, and 38 weeks), MetS components, metabolic parameters including lipid profile, hemoglobin A1c (HbA1c), adiponectin, leptin, and apolipoprotein B, as well as anthropometric and bioimpedance data were obtained. RESULTS: Daily walnut consumption for 16 weeks improved MetS status, resulting in 28.6%-52.8% reversion rates for individual MetS components and 51.2% of participants with MetS at baseline reverted to a normal status after the walnut intervention. Significant improvements after walnut intake, compared to control intervention, in high-density lipoprotein cholesterol (HDL-C) (P = 0.028), fasting glucose (P = 0.013), HbA1c (P = 0.021), and adiponectin (P = 0.019) were observed after adjustment for gender, age, body mass index, and sequence using a linear mixed model. CONCLUSION: A dietary supplement of 45 g of walnuts for 16 weeks favorably changed MetS status by increasing the concentration of HDL-C and decreasing fasting glucose level. Furthermore, consuming walnuts on a daily basis changed HbA1c and circulating adiponectin levels among the subjects with MetS. This trial is registered at ClinicalTrials.gov as NCT03267901.

Objectives: The purpose of this study was to investigate the blood biochemical characteristics, comorbidities, dietary intake, and other risk factors leading to poor glycated hemoglobin (HbA1c) control in elderly Korean diabetes patients over 65 years of age. Methods: Data from the 4^th (2007-2009) and the 7^th (2016-2018) Korea National Health and Nutrition Examination Surveys (KNHANES) were used. Socio-demographic characteristics (age, gender, region, household income, education level, marital status, nutrition education, diabetes duration and diabetes treatment), lifestyle characteristics (drinking, smoking, regular walking, and subjective health perception), anthropometric characteristics (height, weight, and waist circumference), blood biochemical characteristics (HbA1c, high- density lipoprotein cholesterol, triglycerides, total cholesterol, blood urea nitrogen, and blood creatinine), co-morbidities (obesity, hypertension, hypercholesterolemia, hypertriglyceridemia, and anemia), energy and nutrients intake, food group intake, and HbA1c control-related risk factors were compared. Results: Compared to the 4^th survey, the 7^th survey showed an increase in diabetes prevalence among men, an increase in the prevalence of diabetes in the older patients, and an increase in the duration of diabetes. The energy ratio from carbohydrate consumption in the 7^th survey was lower than in the 4^th. Compared to the 4^th survey, thiamine and riboflavin intake had improved, and the intakes of vitamin A, vitamin C, and niacin had worsened in the 7^th. A comparison of food group intakes showed that there was a decrease in the consumption of whole grains, potatoes, and milk and an increase in the intake of beverages and alcoholic beverages. The risk factors for poor control of HbA1c were the duration of diabetes and co-morbid hypertriglyceridemia in the 4^th survey, whereas subjective health perception, obesity, and hypercholesterolemia as co-morbidities were found to be risk factors in the 7^th in addition to the risk factors highlighted in the 4^th survey. Conclusions: For the future management of elderly Korean diabetes patients, greater care is indicated for men over 75 years, and those with low levels of education. It is necessary to increase the intake of milk and vegetables, and reduce the intake of beverages and alcoholic beverages. In addition, it is necessary to reduce the incidence of obesity, hypercholesterolemia, and hypertriglyceridemia for proper control of blood sugar.

Background: Acute alcoholic intoxication patients (AAIP) are a common public health problem. The aim of this study was to perform a comprehensive laboratory analysis for these patients to investigate the co-morbid medical problem. Methods: We retrospectively reviewed laboratory findings of AAIP who were transferred to the emergency department (ED) from January 2017 to June 2017. Results: A total of 160 male patients were enrolled. Sixteen patients (16/160, 10.0%) and three patients (3/160, 1.9%) had macrocytic anemia and microcytic anemia, respectively. A total of 33 patients (33/160, 20.6%) showed thrombocytopenia ($<150{\times}10^9/L$). Twelve patients (12/159, 7.5%) showed low serum albumin level (<3.5 g/dL). Three patients (3/160, 1.9%) had chronic kidney disease stages 3-4 based on estimated glomerular filtration rate. Six patients (6/27, 22.2%) had high hemoglobin A1c (HbA1c) level (>7.0%). Positive rates of hepatitis B surface antigen and antiHBs antibody (anti-HBs Ab) were 3.5% (5/141) and 49.0% (68/141), respectively. Conclusion: Patients with AAIP who were transferred to ED had various laboratory abnormalities (anemia, thrombocytopenia, high HbA1c). They had low positive rate of anti-HBs Ab. This might be a public health problem, suggesting the need of hepatitis B virus vaccination program for AAIP. Our data suggest the need of further nationwide studies.

Purpose: The aim of the study was to evaluate the effect of self-monitoring of blood glucose (SMBG)-based Diabetes Self-Management Education (DSME) on glycemic control in type 2 diabetes. Methods: This study was designed to compare changes in glycemic control over 12months in SMBG-based DSME group (n=65) versus control group (n=65). Data were obtained from medical records type 2 diabetic patients treated with oral antidiabetic agents and above HbA1c 7.0% from June 2006 to August 2008. All participants completed DSME defined as informational intervention of lifestyle habits and reinforcement of educational Monthly News letter delivered by the diabetes nurse educator. SMBG-based DSME group requested to measure blood glucose 7 times a day for a week and to record their diary and received counseling with a focus on diet and lifestyle during the education. Assessments were conducted baseline, 3, 6 and 12 months. HbA1c was used as an index of glycemic control. Results: 12 months later, the level of HbA1c was reduced by $1.28{\pm}1.68%$ in experimental group and $0.49{\pm}1.05%$ in the control group. We found a significant effect of $Time^*$ Group interaction (p=.013). Conclusion: SMBG-based DSME for patients with type 2 diabetes with oral antidiabetic agents was effective in improving glycemic control and maintaining long-term glycemic control.

This study investigated the effect of community-based health intervention program to improve metabolic disease in Jeju island. There were 50 obese local residents in the experimental group (body mass index, $BMI{\geq}25kg/m^2$). They participated in cooking therapy with nutrition education (4 times), exercise program with proprioceptive neuromuscular facilitation (PNF) and stretching training (9 times), and alternative medicine program with healing touch massage (3 times) during a 3-week period. To evaluate the effectiveness of the program, body composition, blood lipid profiles, blood glucose, and waist circumference were assessed before and after the intervention program. After the program, the value of total cholesterol (TC), glycosylated hemoglobin (HbA1C), diastolic blood pressure, percent body fat, and waist circumference were decreased, and became the normal value. Especially, HbA1C, percent body fat, and waist circumference were significantly decreased (P<0.001) in the experimental group, while HbA1C, percent body fat, and waist circumference were significantly increased (P<0.001) in the control group (N=50), who had no intervention. Our results suggest that metabolic syndrome associated markers need intervention program for improving them. In conclusion, although this study did not analyze the effect of the health intervention program and cooking therapy separately, considering the result of this 3-week, short term program, the effect will be more profuse if cooking therapy and exercise program were performed concurrently.

Purpose: The present study aimed to evaluate the clinical benefit of additional toothbrushing accompanying non-surgical periodontal treatment on oral and general health in patients with type 2 diabetes mellitus (T2DM). Methods: We conducted a doubled-blind randomized controlled trial in 60 T2DM patients between June 2013 and June 2014. The patients were randomly assigned to the scaling and root planing (SRP) group; the scaling and root planing with additional toothbrushing (SRPAT) group, in which additional toothbrushing was performed by toothpick methods; or the control group. Microbiological and oral examinations were performed for up to 12 weeks following treatment. Non-surgical treatment was conducted in the experimental groups. The SRP group received scaling and root planing and the SRPAT group received additional toothbrushing with the Watanabe method once a week from the first visit through the fifth visit. The primary outcomes were changes in haemoglobin A1c (or glycated haemoglobin; HbA1c) levels, serum endotoxin levels, and interleukin-1 beta levels. Periodontal health status was measured by periodontal pocket depth, the calculus index, and bleeding on probing (BOP). Results: Both the SRP and SRPAT groups showed improvements in periodontal health and HbA1c, but the SRPAT group showed significantly less BOP than the SRP group. Furthermore, only the SRPAT group showed a statistically significant decrease in serum endotoxin levels. Conclusions: Non-surgical periodontal treatment was effective in improving HbA1c and serum endotoxin levels in T2DM patients. Furthermore, non-surgical treatment with additional tooth brushing had a more favourable effect on gingival bleeding management.

This study investigated the effects of vitamin C supplementation on the nutritional iron status of 31 adolescent girls, aged 12-15 years, with low hemoglobin levels. They were randomly divided into four groups, and for two groups daily150mg or 900mg of L-ascorbic acid(AsA) was given in three equal doses at three meals during 9 weeks. To another group daily 60mg iron as ferrous sulfate was given in the same way as AsA. The control group was given sugar placebo. Body iron status was monitored through the determination of Hb, Hct, MCHC, and serum ferritin concentrations. Dietary AsA and iron intakes were measured from food consumption surveys performed by 3-day 24-hour recalls. The amount of absorbed iron was estimated from the model of Monsen et al. The average amounts of food iron for four groups were 12.3- 15.0mg and 11.1 - 18.9mg at initial and at final period of the supplementation trial, respectively. The tentatively estimated amount of absorbed iron was significantly increased in the 900mg AsA and iron supplementing groups, but not in the 150mg AsA and placebo groups. Both Hb and MCHC were improved to above normal levels in all groups except the placebo group. Hct was elevated only in the AsA 900mg group whose Hct was relatively lower than the other groups. Serum ferritin concentrations of the four groups, which were as low as 8.50 - 14.39ng/mL on average at the intial periods, augmented significantly to 20.18ng/mL and 26.63ng/mL in the 900mg AsA and iron groups, respectively. Serum ferritin was not elevated in either the AsA 300mg group or the placebo group. The above data indicated that the daily supplementaion of 150mg AsA to the meals containing 12-15mg iron per day promoted Hb levels of adolescent girls with low Hb, and the 900mg AsA supplementing improved not only Hb level but also body iron store. A supplementation of 60mg iron per day appeared to be slightly more effective in improving the iron status in comparison to the 900mg AsA supplement.
