Results: Sixty-five patients (80.2%)had OSA. pAHI, pT90, pODI and min O2 were not correlated to L1-4 BMD, FN BMD or TBS in all participants by multiple regression analyses adjusting for age, gender and BMIPublication Metadata only Serum leptin concentrations in relation to body fat, gender, sex hormones and metabolic covariates in Thais(1999-09-01) Boonsong Ongphiphadhanakul; Suwannee Chanprasertyothin; Laor Chailurkit; Rajata Rajatanavin; Noppawan Piaseu; Mahidol UniversityIn the present study, the relation of serum leptin to adiposity, gender and metabolic covariates in normal Thais was examined. Subjects consisted of 224 individuals aged between 20 - 79 years. Eighty two were men while 142 were women. Data were....0001). The difference still persisted after controlling the adiposity. Compared to premenopausal women, postmenopausal women had higher serum leptin independent of adiposity (P < 0.0001). In men, serum free testosterone was negatively associated with serum leptin (rPublication Metadata only Association between bisphenol A and abnormal free thyroxine level in men(2013-10-01) Chutintorn Sriphrapradang; La Or Chailurkit; Wichai Aekplakorn; Boonsong Ongphiphadhanakul; Mahidol Universityto analysis. BPA was detected in 52.8 % of serum samples with a median concentration of 0.33 (range 0-66.91) ng/mL. We excluded subjects who tested positive for thyroid autoantibody and then stratified the remaining subjects by gender; the analysis showed a... significantly negative correlation between serum BPA and FT4levels in males (r = -0.14, P < 0.001). In contrast, no association was observed in females. BPA was not associated with TSH in either gender.

Faculty of Medicine Ramathibodi Hospital. Department of Medicine and Research Center. We further analyzed data according to DBP genotypes. Only in subjects with the AA (common) genotype, 25(OH)D levels were positively related to BMD and bone markers, while fetuin-A was negatively related to total hip BMD, independently of age, gender... and BMI. Conclusions: The interaction between vitamin D status, as measured by circulating 25(OH)D and DBP rs2282679 genotypes, modified the association between 25(OH)D and BMD and bone markers.
