Sex and Gender as Critical and Distinct Contributors to the Human Brain-Gut-Microbiome Axis
Published in Brain Research Bulletin, 2023
Research practices that consider the complexity and distinctiveness of sex and gender in relation to the human brain-gut-microbiome axis will not only yield improved understanding of this consequential system, but will also enhance the development of treatments for adverse health outcomes with BGMA-related etiologies.

Characteristics of the Oral Microbiome in Youth Exposed to Caregiving Adversity
Published in Brain Behavior & Immunity - Health, 2024
These findings suggest that recent stress may affect the oral microbiome of youth, but that a history of exposure to Caregiving Adversity may alter that relationship. Additionally, several microorganisms were differentially abundant in CA-exposed youth, including depletion of several microorganisms identified in other literature as being responsive to cortisol, as well as increased abundance of potential pathogens. Thus, both recent stress and history of CA are important considerations for researchers and clinicians who work with the oral microbiome.

Oral Microbiome and Cortisol in a Community Sample of Youth
Published:
Salivary cortisol is positively associated with characteristics of the oral microbiome, some of which may indicate increased health risk.
A Gut Feeling: Examining Electrogastrography as a Biomarker of Affective Responses
Published:
Our preliminary data revealed that electrogastrography has potential to be an informative signal in affective research, but data loss to artifacts was a major concern in our study design.
Early Adversity is Associated with Altered Oral Microbiome Composition and a Blunted Correlation Between Cortisol and Microbiome Richness in Youth
Published:
We found that youth with a history of early adversity (specifically, a history of adoption and/or foster care) had slightly but significantly different oral microbiomes than did youth with low adversity, and that the microbiomes of youth with early adversity were less strongly associated with cortisol. However, the oral microbiome was not significantly associated with mental health in our sample.
Gut Microbiome Dysregulation and Reward Circuitry in Youth Exposed to Early Adversity
Published:
Gut microbiome composition is associated with caregiving adversity in youth. Additionally, NAcc-vmPFC resting-state Functional Connectivity (rs-FC) was quadratically associated with age. However, there was not a significant relationship between NAcc-vmPFC rs-FC and microbiome characteristics.
Associaitons of the Gut Microbiome with Caregiving Adversity and Internalizing Symptoms in Youth
Published:
Caregiving adversity moderates curvilinear associations between age and gut microbiome composition in youth ages 1-18. Some of these microbiome characteristics are also associated with internalizing symptoms, including bacteria thought to contribute to short-chain fatty acid fermentation.
Caregiving Adversity and the Oral Microbiome
Published:
Caregiving adversity moderates the association between oral microbiome richness and hair cortisol levels in youth ages 6-16. The main effects of caregiving adversity on oral microbiome composition are small but significant. Associations between oral microbiome composition and internalizing symptoms are limited.
Caregiving Adversity and Internalizing Symptoms in Youth: Role of Gut Microbiome Functional Potential
Published:
Caregiving adversity is associated with several differences in gut microbiome functional pathways in youth ages 6-16. Additionally, adversity significantly moderates the associations between several pathways and internalizing symptoms, as well as transdiagnostic physical symptoms (e.g. fatigue).
Maternal Preconception and Prenatal Stress Impact Children’s Gut-Microbiome-Brain Axis
Published:
Preconception stress experienced by the mother, as well as prenatal and postnatal stress exert lasting impacts on children’s gut-microbiome-brain axis, with potential relevance for children’s psychiatric health.
Youth Exposed to Caregiving Adversity Exhibit Altered Associations Between Diet and the Gut-Microbiome-Brain Axis
Published:
Early caregiving-related adversities exert lasting effects on the gut microbiome that are dependent on age. However, adversity-exposed youth consuming high-fiber, low-sugar diets have higher abundance of gut microorganisms that are potentially beneficial for mental health.
