We determined relationships of the anti-oxidative enzyme, paraoxonase-1 (PON-1), with high density lipoprotein (HDL) subfractions, and tested whether these relationships are stronger than those with HDL cholesterol and apolipoprotein A-I (apoA-I) in subjects with and without type 2 diabetes mellitus (T2DM).', 'Serum PON-1 (arylesterase activity) and HDL subfractions (nuclear magnetic resonance spectroscopy) were determined in 67 T2DM patients and in 56 non-diabetic subjects.', 'PON-1 activity, HDL cholesterol and apoA-I were decreased in T2DM (all p<0.05). The HDL particle concentration was unaltered, but large HDL particles, medium HDL particles and HDL particle size were decreased, whereas small HDL particles were increased in T2DM (all p<0.05). PON-1 was more closely related to HDL cholesterol than to apoA-I (p=0.001). In turn, the positive relationship of PON-1 with the HDL particle concentration and with large HDL particles was stronger than that with HDL cholesterol (both p<0.01). The inverse relationship of PON-1 with T2DM was only modestly attenuated by HDL cholesterol or HDL particle characteristics.
Is serum paraoxonase-1 activity more closely related to HDL particle concentration and large HDL particles than to HDL cholesterol in Type 2 diabetic and non-diabetic subjects?

An association between obesity and otitis media with effusion (OME) has been previously reported. The aim of this study was to evaluate the association between dietary intake and OME when adjusting obesity.', 'We analyzed the differences in dietary intake between children with/without OME who were 4 through 13 years of age using data from a large population-based survey - the Korea National Health and Nutrition Examination Survey - from 2008 through 2012. Data from 4359 participants were analyzed using simple and multiple logistic regression analyses with complex sampling.', 'The BMI category, the proportion of total calorie intake, protein intake, water intake, and Na intake (intake/recommendation), and the distribution of carbohydrate intake were not associated with OME. The distribution of fat intake was associated with OME (each 10% increase of fat calories/total calories: unadjusted odds ratio [OR]=1.331, 95% confidence interval [CI]=1.016-1.744, P=0.038; age- and sex-adjusted OR=1.359, 95% CI=1.028-1.797, P=0.031; adjusted for age, sex and other factors OR=1.392, 95% CI=1.054-1.839, P=0.020). Based on BMI subgroup analysis, the distribution of fat intake was associated with OME in the healthy weight group (each 10% increase of fat calories/total calories: unadjusted OR=1.393, 95% CI=1.017-1.909, P=0.039; adjusted OR=1.470, 95% CI=1.051-2.055, P=0.024) but not in the obese group.
Is a high-fat diet associated with otitis media with effusion?

Locally advanced colorectal cancer often requires extended resection to radically remove all tumor. This is the only chance for cure in these patients, but a higher complication rate would be expected. To evaluate the overall benefit for the patient, this study assesses morbidity and mortality as well as long-term survival of patients who underwent extended resection for a T3-T4 carcinoma.', 'Two hundred twenty patients with locally advanced adenocarcinoma of the colorectum were included. One hundred fifty presented with a T3 and 70 with a T4 tumor. Eighty-three patients underwent extended resection. In 38 patients extended en bloc resection was performed because of inflammatory adherence mimicking infiltration. Thirty-three patients who underwent extended resections were over 70 years of age. There were no significant differences between the groups that underwent extended or nonextended resections in age, sex, stage, or grading.', 'pT4 lesions were significantly more frequent in the extended resection group than in the nonextended resection group. Mean survival was 44 months after extended resections and 45 months after nonextended resections. In the extended resection group there was no significant difference in mean survival between pT3 and pT4 stage patients within 46 and 38 months, respectively. In patients who underwent nonextended resections, however, there was a significant difference in mean survival within 48 months for pT3 and 28 for pT4 patients (P < 0.05). Postoperative morbidity and mortality were comparable between the extended resection group and the non-extended resection group. The presence of residual tumor influenced prognosis of patients significantly; R0 resections fared significantly better than patients who underwent R1 or R2 resections (55 and 51 to 14/12 and 23/8 months) (P < 0.01). Nodal stage and International Union Against Cancer stage were also significant determinants of prognosis. After extended resections mean survival morbidity and 30-day mortality in patients more than 70 years was similar to those less than 70 years.
Are extended resections beneficial for patients with locally advanced colorectal cancer?
