Objectives: To investigate the effect of a worksite-based dietary intervention program for the management of metabolic syndrome (MS) among male employees. Methods: A dietary intervention program combining individual and environmental approach was implemented targeting white-collar employees at a worksite located in Seoul for 10 weeks. Out of 104 employees having agreed to participate in the program, those having three or more out of five components of MS and having two components, including a waist circumference component were classified into "the high risk group" (n=41) and received group nutrition education and individual nutrition counseling three times each. The rest of the study subjects were considered as "the low risk group" (n=63). The food environment at the worksite, where both the high and low risk groups were exposed, was changed to promote healthy eating. Physical data including MS components were collected and a questionnaire on dietary behaviors was administered before and after the intervention. The data from the high risk group (n=17) and the low risk group (n=20), excluding the subjects ineligible for or failed to complete the study (n=67), were analyzed. The difference before and after intervention was tested for significance by Wilcoxon signed-rank tests. Results: Weight, body mass index (BMI), waist circumference, blood pressure, HDL-cholesterol, and HbA1c and the healthy dietary practice score improved significantly after intervention in the high risk group. The median number of MS components decreased significantly from 3.0 to 1.0 in the high risk group. In the low risk group, only HbA1c significantly decreased. Conclusions: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.

The effect of high egg intake on metabolic syndrome (MetS), a major risk factor for cardiovascular disease (CVD), has not been clearly elucidated. This study was conducted to review the literature related to egg consumption and the risk of metabolic disease as well as to examine the association between high egg intake and MetS in Korean adults. A literature review was conducted using published papers in PubMed and EMBASE through December 2017. We have reviewed 26 articles, which were associated with egg consumption and metabolic diseases, and found that the results were controversial. Therefore, we analyzed data from 23,993 Korean adults aged 19 yrs and older. MetS was defined based on criteria from the Adult Treatment Panel III. Egg consumption of 4-6 times/wk and 1 time/day were significantly associated with reduced prevalence of MetS (Odds ratio (OR)=0.82; 95% Confidence interval (CI)=0.71-0.95 for 4-6 times/wk, OR=0.83; 95% CI=0.69-0.99 for 1 time/day) compared to those who consumed eggs less than once monthly. However, consuming two or more eggs per day was not associated with MetS. As for the components of MetS, an egg intake of once daily decreased the prevalence of abdominal obesity and an intake of 2-7 eggs weekly was shown to prevent a reduction in the high-density lipoprotein cholesterol levels. This study suggests that while consuming eggs 4-7 times weekly is associated with a lower prevalence of MetS, consuming two or more eggs daily is not associated with a reduced risk for MetS.

The tumour lysis syndrome (TLS) is a group of metabolic abnormalities caused by rapid and unexpected release of cellular components into the circulation as a result of massive destruction of rapidly proliferating malignant cells. It usually develops in patients with hematologic malignancies like acute lymphoid leukemia, non-Hodgkin and Burkitt's lymphoma after initiation of chemotherapy or may, rarely, occur spontaneously. Though TLS is seldom observed in relation to solid tumours, there have been reports of connections with examples such as lung, liver, breast, gastric carcinomas. The clinical manifestations of TLS include hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia. These indications if untreated lead to life-threatening complications such as acute renal failure, cardiac arrhythmias, seizures, and eventually death due to multiorgan failure. Therefore early detection of TLS is of vital importance. This can be accomplished by identification of high risk patients, implementation of suitable prophylactic measures andmonitoring of the electrolyte levels in patients undergoing chemotherapy.

The clustering of insulin resistance with hypertension, glucose intolerance, hyperinsulinemia, increased triglyceride and decreased HDL cholesterol levels, and central and overall obesity has been called syndrome X, or the insulin resistance syndrome(IRS). To develop a nutrition service for IRS, this study was performed to evaluate the prevalence of each component of the metabolic abnormalities of IRS and analyze the clustering pattern of IRS among subjects living in the Taegu community. Participants in this study were 9234(mean age ; M/F 48/40yrs);63.5% were men, 24.4% were obese, 13.3% had hypertension. 3.7% had hyperglycemia, and 32.4% had hyperlipidemia. The IRS was defined as the coexistence of two or more components among metabolic abnormalities; obesity, hypertension. hyperglucemia and hyperlipidemia. The prevalence of IRS in Taegu was 19.2%(M/F:20.8%/16.4%), the clustering of these fisk variables was higher in advanced age group. Among the subjects of IRS having two of more diseases, 75.6% were obese, the pattern were similar in men and women. The younger, the higher the prevalence of obesity associated clustering patterns. The prevalence of obesity associated patterns among the hyperglycemia associated clustering patterns was 44.5%. The samples of the representative clustering patterns were obesity and hyperlipidemia (8.0%), hypertension and hyperlipidemia(3.2%), hypertension, obesity and hyperlipiemia(3.1%), hypertension and obesity(2.3%), and hyperglycemia and hyperlipidemia(0.8%). The clustering of obesity and hyperlipidemia until 50 year old groups, and the clustering of hypertension and hyperlipidemia in the 60 and 70 age groups were the most prevalent. We concluded that insulin resistance syndrome was a relatively common disorder in the Taegu community, and prevalence and the characteristics of the intervention strategies for IRS are desired, an effective improvement will be achieved.

Dynamic energy balance can give clinicians important answers for why obesity is so resistant to control. When food intake is reduced for weight control, all components of energy expenditure change, including metabolic rate at rest (resting energy expenditure [REE]), metabolic rate of exercise, and adaptive thermogenesis. This means that a change in energy intake influences energy expenditure in a dynamic way. Mechanisms associated with reduction of total energy expenditure following weight loss are likely to be related to decreased body mass and enhanced metabolic efficiency. Reducing calorie intake results in a decrease in body weight, initially with a marked reduction in fat free mass and a decrease in REE, and this change is maintained for several years in a reduced state. Metabolic adaptation, which is not explained by changes in body composition, lasts for more than several years. These are powerful physiological adaptations that induce weight regain. To avoid a typically observed weight-loss and regain trajectory, realistic weight loss goals should be established and maintained for more than 1 year. Using a mathematical model can help clinicians formulate advice about diet control. It is important to emphasize steady efforts for several years to maintain reduced weight over efforts to lose weight. Because obesity is difficult to reverse, clinicians must prioritize obesity prevention. Obesity prevention strategies should have high feasibility, broad population reach, and relatively low cost, especially for young children who have the smallest energy gaps to change.

Whether the $FTO$ polymorphisms interact with environmental factors has not yet been evaluated in associations with metabolic syndrome (MS) risk. The present study investigated the association of the $FTO$ rs9939609 genotypes, body mass index (BMI), and lifestyle-related factors including smoking, alcohol drinking, physical activity, and diet with MS incidence. A population-based prospective cohort study comprised 3,504 male and female Koreans aged 40 to 69 years. At the beginning of the study, all individuals were free of MS and known cardiovascular disease. Incident cases of MS were identified by biennial health examinations during a follow-up period from April 17, 2003 to April 15, 2009. Pooled logistic regression analysis was applied to obtain relative odds (RO) of MS with its 95% confidence interval (CI). After controlling for potential MS risk factors, we observed no association between the rs9939609 genotypes and MS incidence. In analysis stratified by BMI, however, carriers with the $FTO$ risk allele whose BMI is $29kg/m^2$ or greater showed an approximately 6-fold higher RO (95% CI: 3.82 to 9.30) compared with non-carriers with BMI less than $25kg/m^2$. In particular, the association between the rs9939609 variants and MS risk was significantly modified by high BMI (P-value for interaction < 0.05). Such significant interaction appeared in associations with central obesity and high blood pressure among the MS components. Because carriers of the $FTO$ risk alleles who had BMI of $29kg/m^2$ or greater are considered a high risk population, we suggest that they may need intensive weight loss regimens to prevent MS development.

Objectives: This study was performed to investigate the associations between the metabolic syndrome (MetS) and inflammatory markers. Methods: This cross-sectional analysis was performed using data from 1578 Koreans aged 40-69 years residing in a rural area. We investigated associations between MetS and circulating high sensitivity C-reactive protein (hs-CRP), white blood cells (WBC) and adiponectin. MetS was defined using the criteria proposed by the National Cholesterol Education Program Adult Treatment Panel III (ATP-III). Results: Increased WBC counts and hs-CRP levels and decreased adiponectin levels were observed in subjects with MetS. WBC, hs-CRP and adiponectin levels linearly deteriorated with an increase in the number of MetS components (all ptrend <0.005). Finally, adjusted odds ratios (ORs) for the risk of MetS by increase/decrease in 3 inflammatory markers were calculated by multivariate logistic regression analyses. In terms of changes in inflammation markers, in men, the adjusted ORs (95% confidence interval) were 1.15 (1.01-1.31) for WBC, 1.64 (1.02-2.64) for hs-CRP, and 0.19(0.08-0.45) for adiponectin, whereas corresponding adjusted ORs (95% Cls) in women were 1.27 (1.15-1.40), 0.98 (0.67-1.42), 0.09 (0.04-0.18), respectively. Conclusions: Serum adiponectin levels and WBC counts were found to be strongly associated with MetS in both sexes. However, hs-CRP lost its significance after adjusting for BMI and other inflammatory markers in women. This study shows that inflammatory response is associated with MetS in the Korean population. Further prospective studies are necessary to confirm the contribution made by inflammatory markers to the development of MetS.

High blood pressure (BP) is the most frequent risk factor among metabolic syndrome components. The control of hypertension is very important to prevent the cardiovascular risk in metabolic syndrome. The dysfunction of calcium channel is responsible in the regulation of the vascular muscle contribution to hypertension. Calcium channel, voltage-dependent, P/Q type, alpha-1A subunit (CACNA1A) gene is located in brain and known to control the intracranial hypertension. In this study, we investigate whether the polymorphisms of CACNA1A gene is associated with hypertension. The 49 CACNA1A genotypes were determined using the Affymetrix Genotyping chip array in 92 hypertension and 279 control individuals from a Korean population. Logistic and multiple regression models were employed to analyze the genetic contributions of polymorphisms. Out of 49 polymorphisms, six SNPs (rs12611029, rs16035, rs7259944, rs10419472, rs17777900, and rs4926294) showed a significant association with hypertension in three alternative models (codominant, dominant, and recessive models; P<0.05 after adjusting for age and sex). Our results suggest that the CACNA1A gene may be associated with hypertension in the Korean population.
