Association between lifestyle, dietary, reproductive, and anthropometric factors and circulating 27-hydroxycholesterol in EPIC-Heidelberg

AbstractPurposeGiven that 27-hydroxycholesterol (27HC) is the first identified endogenous selective estrogen receptor modulator, the aim of this study was to investigate the extent to which dietary or lifestyle factors impact circulating 27HC concentrations in a large-scale setting.MethodsThis cross-sectional analysis included 1,036 women aged 35 –65 years who served as controls in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Heidelberg breast cancer case–control study. Circulating 27HC was quantified in serum using liquid chromatography/tandem mass spectrometry. Generalized linear models were used to investig ate the association between 27HC concentrations and dietary habits, and lifestyle, reproductive, and anthropometric factors.ResultsHigher concentrations of 27HC were observed among postmenopausal relative to premenopausal women (geometric mean 200.5 vs. 188.4  nM,p = 0.03), whereas women reporting ever full-term pregnancy had lower concentrations of 27HC relative to never (191.4 vs. 198.6;p = 0.03). Significant trends were observed showing higher concentrations with relatively high levels of physical activity (ptrend = 0.03) and alcohol consumption (ptrend = 0.01), and women currently smoking at blood collection (ptrend

Conclusions: In the context of this framework, cortisol may serve as a biomarker for the development of AUD, as well as a biomarker of risk or relapse. This review ends with both theoretical and clinical implications, as well as directions for future research. PMID: 32493131 [PubMed - as supplied by publisher]

This study sought to determine the incidence rates of all gynecologic, including peritoneal, malignancies in the U.S. Active Duty population compared to the general US population as reported in the Surveillance, Epidemiology, and End Results Program database. MATERIALS AND METHODS: Gynecologic cancers diagnosed in U.S. Active Duty women aged 20-59 between 2004 and 2013 were retrospectively ascertained. Cancer cases were identified in both the Automated Central Tumor Registry and the Military Health System Data Repository. All cases in Automated Central Tumor Registry plus cases recorded in Military Health System Data R...

CONCLUSIONS: Fusion genes were the most common genetic cause of pediatric PTCs. Fusion gene positive PTCs showed more aggressive behavior than fusion gene negative PTCs. Several novel rearrangements were identified. Fusion genes seem to be a molecular marker number one in pediatric PTC patients. PMID: 32495721 [PubMed - as supplied by publisher]

Conclusion The periconceptional environment and lifestyle factors modify sperm epigenome. This alteration might be maintained in the zygote and throughout development, thereby leading to the inheritance of newly acquired pathologies. The role of sperm miRNA, not only as innovative markers of fertility issues but also as vectors involved in the inheritance of paternal diseases, appears to be crucial. Overweight and obesity seem to alter sperm miRNA profile, thereby leading to transmission of different miRNA profiles in zygote, with consequences on embryo development. In long term, metabolic disorders have been described in...
