About this Research Topic

Background

The field of probiotics and their impact on children's health has garnered significant attention in recent years, particularly concerning their potential therapeutic effects on gastrointestinal, respiratory, allergic, and metabolic diseases. Despite the proliferation of market-oriented probiotic products, there remains a substantial gap in robust, evidence-based research supporting their efficacy in improving children's health. The strict definition of probiotics necessitates that clinical studies be strain-specific, yet many products lack this precision in their claims. International professional bodies have emphasized the importance of using only those probiotic strains with proven clinical efficacy, administered in appropriate dosages, as adjuvants in treating children's health issues. While bifidobacteria and lactobacilli dominate the market, the diversity in strain composition, colony-forming units (CFUs), and biological activity among products is vast. Currently, there is a dearth of research on how specific probiotic strains, with precise CFUs and intervention durations, influence the gut flora and, consequently, the health of developing children. Although randomized controlled trials (RCTs) are the gold standard for establishing causal relationships, such studies, especially in the context of developing children, are notably lacking.

This research topic aims to bridge the gap in clinical studies by exploring how specific probiotic supplementation alters the gut microbiota's composition and functional activity in children with specific diseases, such as gastrointestinal, respiratory, or allergic conditions. The objective is to provide evidence-based recommendations for consumers and healthcare professionals by focusing on the specific strains used, dosages, intervention durations, and targeted diseases. By identifying effective strains through clinical studies, this research will contribute to improving children's health with strain-specific probiotic products.

To gather further insights into the strain-specific impacts of probiotics on children's health, we welcome articles addressing, but not limited to, the following themes:
- The efficacy and/or effectiveness of strain-specific probiotic supplements for specific diseases in children, such as gastrointestinal, respiratory, and allergic diseases, through clinical trials and case reports.
- Comprehensive comparative analysis of different specific strains of probiotics on the same developmental disease in children or the same probiotic strain on different diseases, considering supplementation methods, doses, and duration, through narrative and/or systematic reviews.
- Review of the possible mechanisms by which specific bacterial strains can effectively assist in treating specific diseases in childhood.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
