Breakfast patterns are associated with metabolic syndrome in Korean adults

The Korean diet, including breakfast, is becoming more Western, which could increase the risk of metabolic syndrome. Our aim was to assess whether breakfast patterns are associated with risk for metabolic syndrome in Korean adults. The study subjects (n = 371; 103 men, 268 women) were employees of Jaesang Hospital in Korea and their acquaintances, and all subjects were between 30 and 50 years old. The data collected from each subject included anthropometric measurements, three-day food intake, blood pressure (BP) and blood analyses. The three breakfast patterns identified by factor analysis were "Rice, Kimchi and Vegetables", "Potatoes, Fruits and Nuts" and "Eggs, Breads and Processed meat". The "Rice, Kimchi and Vegetables" pattern scores were positively correlated with systolic (SBP) and diastolic blood pressure (DBP) measurements in men (P < 0.05) and with serum triglyceride (TG) levels in women (P < 0.05). The "Eggs, Breads and Processed meat" pattern scores correlated positively with weight, body mass index (P < 0.05) and serum TGs (P < 0.01) in men. The "Potatoes, Fruits and Nuts" pattern was associated with lower risk of elevated BP (OR 0.49, 95% CI 0.28-0.88) and fasting glucose levels (OR 0.51, 95% CI 0.26-1.00). In contrast, the "Eggs, Breads and Processed meat" pattern was associated with increased risk of elevated TGs (OR 2.06, 95% CI 1.06-3.98). Our results indicate that reducing the consumption of eggs, western grains and processed meat while increasing fruit, nut and vegetable intake for breakfast could have beneficial effects on decreasing metabolic syndrome risk in Korean adults

Skipping breakfast is associated with diet quality and metabolic syndrome risk factors of adults

The aim of the present study was to assess the effects of skipping breakfast on diet quality and metabolic disease risk factors in healthy Korean adults. Subjects included 415 employees (118 men, 297 women; 30-50 years old) of Jaesang Hospital in Korea and their acquaintances. Data collected from each subject included anthropometric measurements, 3-day dietary intake, blood pressure, and blood analyses. The subjects were classified into three groups based on the number of days they skipped breakfast: 'Regular breakfast eater', 'Often breakfast eater', or 'Rare breakfast eater'. Participants in the 'Rare breakfast eater' group consumed less rice, potatoes, kimchi, vegetables, fish and shellfish, milk and dairy products, and sweets than did participants in the other two groups (P for trend < 0.05) and ate more cookies, cakes, and meat for dinner (P for trend < 0.05). Participants in the 'Rare breakfast eater' group consumed less daily energy, fat, dietary fiber, calcium, and potassium than did participants in the other groups (P for trend < 0.05). The percent energy from carbohydrates was lower and fat intake was higher in the 'Rare breakfast eater' group than in the other groups (P for trend < 0.01). When diets were compared using the Acceptable Macronutrient Distribution Range for Koreans, 59.1% of subjects in the 'Rare breakfast eater' group consumed more energy from fat compared with the other two groups (P < 0.005). According to the Estimated Average Requirements for Koreans, intake of selected nutrients was lower in the 'Rare breakfast eater' group than in the other two groups (P < 0.05). The risk of elevated serum triglycerides was decreased in the 'Rare breakfast eater' group (OR, 0.3 [0.1-1.0], P for trend = 0.0232). We conclude that eating breakfast regularly enhances diet quality, but may increase the risk of elevated serum triglycerides

Fabrication of ??-CoV3O8 nanorods embedded in graphene sheets and their application for electrochemical charge storage electrode

Fabrication of ??-CoV3O8 nanorods embedded in graphene sheets and its application as electrochemical charge storage electrodes is reported. From surfactant treatment of raw graphite, graphene was directly prepared and its nanocomposite with ??-CoV3O8 nanorods distributed between graphene layers (??-CoV3O8-G) was synthesized by hydrothermal method. When applied as anode in lithium-ion batteries, the ??-CoV3O8-G anode exhibits greatly improved charge and discharge capacities of 790 and 627 mAhbold dotg-1, respectively, with unexpectedly high initial efficiency of 82%. The observed discharge capacity reflected that at least 3.7 mol of Li+ is selectively accumulated within the ??-CoV3O8 phase (LixCoV3O8, x &gt; 3.7), indicative of significantly improved Li+ uptake when compared with aggregated ??-CoV3O8 nanorods. Moreover, very distinct peak plateaus and greatly advanced cycling performance are observed, showing more improved Li+ storage within the ??-CoV3O8 phase. As a supercapacitor electrode, moreover, our composite electrode exhibits very high peak pseudocapacitances of 2.71 Fbold dotcm&amp;#8722;2 and 433.65 Fbold dotg&amp;#8722;1 in ??-CoV3O8 phase with extremely stable cycling performance. These remarkably enhanced performances in the individual electrochemical charge storage electrodes are attributed to the novel phase formation of ??-CoV3O8 and its optimized nanocomposite structure with graphene, which yield fast electrical conduction through graphene, easy accessibility of ions through the open multilayer nanosheet-structure, and a relaxation space between the ??-CoV3O8-G

Short Communication: HIV-1 Transmission Networks Across South Korea.

Molecular epidemiology can help clarify the properties and dynamics of HIV-1 transmission networks in both global and regional scales. We studied 143 HIV-1-infected individuals recruited from four medical centers of three cities in South Korea between April 2013 and May 2014. HIV-1 env V3 sequence data were generated (337-793 bp) and analyzed using a pairwise distance-based clustering approach to infer putative transmission networks. Participants whose viruses were ≤2.0% divergent according to Tamura-Nei 93 genetic distance were defined as clustering. We collected demographic, risk, and clinical data and analyzed these data in relation to clustering. Among 143 participants, we identified nine putative transmission clusters of different sizes (range 2-4 participants). The reported risk factor of participants were concordant in only one network involving two participants, that is, both individuals reported homosexual sex as their risk factor. The participants in the other eight networks did not report concordant risk factors, although they were phylogenetically linked. About half of the participants refused to report their risk factor. Overall, molecular epidemiology provides more information to understand local transmission networks and the risks associated with these networks
