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...

Conclusions In conclusion, articles in this Research Topic made a very significant contribution to our understanding of the role played by environmental factors, dysbiotic conditions, and infections in triggering diseases. Since this is a rapidly expanding area of research, many other factors contributing to the onset of these diseases are not covered here. We are confident, however, that further studies will expand the list as well as bring a better understanding of mechanisms involved in the onset of autoimmune and autoinflammatory diseases. Author Contributions All authors listed have made a substantial, direct and i...

This study aims to determine the complementary effects of omega-3 and vitamin E supplements on certain oxidative stress indices in obese and overweight women with polycystic ovary syndrome. MATERIALS AND METHODS: This double-blind, randomized clinical trial was performed on polycystic ovary syndrome subjects with BMI > 25. Patients were randomly allocated into two groups to receive either 2 g of omega-3 plus 400 IU of vitamin E, or a placebo, for 8 weeks. At the beginning and the end of the study, total antioxidant capacity, glutathione levels, catalase activity, malondialdehyde concentrations, a...
