Association Between Periodontal Disease and Metabolic Syndrome
ABSTRACT Objectives: Metabolic syndrome is a complex medical disorder characterized by visceral fat-type obesity involving hypertension, and abnormal glucose and lipid metabolism. The objective of this study was to investigate the relationship between periodontal disease and components of metabolic syndrome (obesity, lipid abnormality, hypertension, and hyperglycemia) in industrial workers of a single company in Tokyo, Japan. Methods: The study subjects consisted of 2,478 adult employees (2,028 men and 450 women; mean age: 43.3 years). The association between the presence of periodontal pockets and components of metabolic syndrome was investigated cross-sectionally using multiple logistic regression analysis, odds ratios (ORs), and 95 percent confidence intervals (CIs). Results: Body mass index, blood pressure, triglycerides, fasting blood glucose, and hemoglobin A1c (HbA1c) were significantly elevated (P < 0.05) in patients with periodontal pockets of 4 mm or more. We found that the OR of the presence of periodontal pockets adjusted for age, gender, and smoking habit was 1.8 (96 percent CI = 1.4-2.3) when the subjects with two positive components and without positive component were compared. And it was 2.4 (96 percent CI = 1.7-2.7) when the subjects with three or four positive components and without positive component were compared. Conclusions: Our findings suggest an association between periodontal disease and metabolic syndrome in Japanese workers between the ages of 20 and 60 years.

ABSTRACT: Multidisciplinary research on aspects of future power systems can be both challenging and rewarding as demonstrated by three institutions with distinct disciplinary perspectives co-researching demand side participation within the Supergen Networks Consortium. This paper seeks to identify and describe different facets of our combined approach and to provide a template for multidisciplinary working within the context of future electricity networks. Facets of the respective research perspectives are identified including: epistemology, scale, sector and methodology. Whilst it is evident that a unified perspective is not achievable, a 'daisy chain' of co-research is proposed that unifies technical, economic and social perspectives whilst accommodating differences within each of the facets. The 'daisy chain' analogy enables overlap as well as distinctiveness to be represented.Future Power Systems, 2005 International Conference on; 12/2005

ABSTRACT: High-frequency radar offers oceanographers a powerful yet convenient means of measuring coastal ocean currents and other air/sea interaction variables from land-based sites. The paper addresses the potential such a system offers for detecting the physically significant coastal circulation events known as coastal upwelling and relaxation. A high-frequency radar was in operation from April, 1990 until September, 1992 on the California Coast (USA) overlooking the Pacific Ocean near Monterey. Periods of months of uninterrupted radar operation have allowed the production of an unparalleled data set which includes radial ocean surface currents measured at five angles and eight range bins. Correlation of low-pass-filtered current measurements with shore-based measurements of sea surface temperature and buoy-measured wind speeds shows evidence of coastal upwelling and relaxation eventsGeoscience and Remote Sensing Symposium, 1993.
