Individuals preferred to take the "screen and treat" strategy for the prevention of gastric cancer. Further intervention study is warranted to see if implementation of decisional support would improve decision quality and patient outcomes.

The association between temperature (cold or heat) and cardiovascular mortality has been well documented. However, few studies have investigated the underlying mechanism of the cold or heat effect. The main goal of this study was to examine the effect of temperature on dehydration markers and to explain the pathophysiological disturbances caused by changes of temperature. We investigated the relationship between outdoor temperature and dehydration markers (blood urea nitrogen (BUN)/creatinine ratio, urine specific gravity, plasma tonicity and haematocrit) in 43,549 adults from Seoul, South Korea, during 1995-2008. We used piece-wise linear regression to find the flexion point of apparent temperature and estimate the effects below or above the apparent temperature. Levels of dehydration markers decreased linearly with an increase in the apparent temperature until a point between 22 and 27 °C, which was regarded as the flexion point of apparent temperature, and then increased with apparent temperature. Because the associations between temperature and cardiovascular mortality are known to be U-shaped, our findings suggest that temperature-related changes in hydration status underlie the increased cardiovascular mortality and morbidity during high- or low-temperature conditions.

Objectives: To evaluate the relationship between abdominal obesity and microalbuminuria (MA) in normotensive, euglycemic Korean men. Design: A cross-sectional study at a health screening center. Subjects: A total of 1321 healthy, normotensive Korean men, aged 20-78 years, with a fasting plasma glucose level o100 mg/dl. Measurements: Height, weight, and waist; systolic blood pressure (SBP); diastolic blood pressures (DBP); urinary albumin to creatinine ratio (ACR); fasting glucose, insulin, lipids, C-reactive protein (CRP), and white blood cell count. Waist circumference (WC) was used to indicate abdominal obesity and a single measurement of ACR was used to estimate MA. We also calculated body mass index (BMI) based on weight and height. Results: Mean BMI, WC, and SBP were significantly higher in subjects with MA than in those without (24.874.1 vs 23.872.7 kg/m 2 , 8679 vs 8378 cm, and 11575 vs 11277 mmHg, respectively). Multiple logistic regression analyses showed that only WC and SBP were independent predictors of MA. Conclusion: WC and SBP were positively associated with MA in normotensive and euglycemic Korean men.

PFOS and PFDoDA exposures were positively associated with IR and oxidative stress, and vitamin C supplementation protected against the adverse effects of PFOS and PFDoDA on IR.
