Special Issue Information

Dear Colleagues,

Gut microbiota is critically involved in maintaining the integrity of the gastrointestinal tract, the gut mucosal homeostasis, and host nutritional metabolism. The specific signatures of intestinal microbiome and alterations are likely to play an important (but still underestimated) role in determining susceptibility and resilience to disease outcomes locally and systemically. The human and animal gut microbiomes are shaped by diet and host factors, in which different dietary patterns acutely and persistently perturb microbial communities. It is important to understand the complex interactions between microbiota and host immunity, including which and how gut microbiota metabolizes these dietary elements, and the molecular links and underlying mechanisms of how diet-reshaped gut microbes and their metabolites modulate host immunity systems, physiological metabolism, and health. In this Special Issue, we will pay attention to how those elements from different dietary patterns that modulate gut microbiota, and how specific gut microbes and their metabolites work to be involved in the development of chronic diseases, inflammatory bowel disease, etc.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Background: Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine syndromes affecting women at reproductive age. With increasing knowledge of the role of the microbiota in the pathogenesis of PCOS, new management strategies began to emerge. However, data on the impact of established treatment regimens, such as metformin and oral contraceptive agents, on the gut microbiota composition are scarce. This study aimed to evaluate the specificity of the gut microbiota in women with PCOS before and after treatment with oral contraceptives. Methods: We have systematically searched the following databases: PubMed/MEDLINE, Scopus, Web of Science and Google Scholar. The last search was performed on 13 May 2024. We included only full-text original research articles written in English. The risk of bias was assessed using a modified version of the Newcastle–Ottawa Scale. Results: The above described search strategy retrieved 46 articles. Additionally, 136 articles were identified and screened through Google Scholar. After removing duplicates, we screened the titles and abstracts, resulting in three eligible articles constituting the final pool. They were published between 2020 and 2022 and are based on three ethnically distinct study populations: Turkish, Spanish and American. The studies included a total of 37 women diagnosed with PCOS and using OCs. Conclusions: OC treatment does not seem to affect the gut microbiota in a significant way in patients with PCOS in short observation. Well-designed randomized controlled studies with adequate, unified sample size are lacking. Full article
