MedicalResearch.com: What is the background for this study? Can you briefly explain what is meant by a bacteriophage?
Response: Child stunting a severe growth impairment, globally affecting about 1 in 5 of children. The correlation between altered gut microbiota and stunting is already known. In contrast to what we know about the link between altered gut bacteria and stunting, the role of phages was not explored.
Phages are the bacterial viruses that match the number of bacterial cells by a 1:1 ratio in the human gut. They are central to the biogeochemistry of most ecosystems by driving bacterial physiology, diversity, and abundance. Therefore, we expect a significant role for them in the human gut.

Response: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are chemical groups that have had a wide variety of uses due to their ability to their ability to repel water and stains. They might be found in food packaging, water-repellant clothing and carpeting, paints, fire-fighting foam, and water, for example. Although many are no longer manufactured in the United States, PFAS persist in the environment as they do not readily break down. Adverse health effects have been speculated especially for low birthweight babies, immunological effects, certain cancers and thyroid hormone disruption.1 With these considerations, we hypothesized that there may be an association of PFAS with tooth development and subsequent dental caries (cavities).

MedicalResearch.com: What is the background for this study?
Response: Heart failure (HF) with preserved ejection fraction (HFpEF) accounts for approximately 50% of cases of HF and to date clinical trials with HFpEF patients have failed to produce positive outcomes. Part of this is likely due to the lack of HFpEF animal models for preclinical testing. Our lab addressed this gap in knowledge by developing an animal model that mimics critical features of the human HFpEF phenotype. We performed an in-depth cardiopulmonary characterization highlighting that the model has characteristics of human disease. We then tested the effects of a pan-HDAC inhibitor, vorinostat/SAHA, in collaboration with Dr. Timothy McKinsey, who is an expert in HDAC inhibitors and recently published work1 that laid the foundation for this study.

Response: E-cigarette use increased dramatically from 11.7% to 27.5% for high school students and from 3.3% to 10.5% for middle school students during the periods of 2017 - 2019. In September 2018, the Food and Drug Administration (FDA) warned that youth e-cigarette use is reaching an epidemic proportion.
Exposure to secondhand aerosol (SHA) from e-cigarettes is not harmless as e-cigarettes aerosol contains nicotine and potentially harmful substances, including carbonyl compounds, TSNAs, heavy metals, and glycols. This study analyzed the 2015-2018 National Youth Tobacco Survey (NYTS) and the main findings are:
