The first year postpartum is a sensitive time for maternal eating behaviors including emotional, external and restrained eating, which have all been associated with negative health outcomes. Furthermore, among women with a history of trauma, the stress of the postpartum period and early parenting may replicate feelings of helplessness and overwhelm experienced during childhood trauma, which may further contribute to these eating behaviors. Although evidence has shown how mothers eat during this time has long-term implications for infants' eating and health, limited research has characterized eating trajectories and associations with women's history of childhood trauma exposure during this critical period.

Background: In response to contracting an infection, individuals usually display a suite of external signs (including sickness behavior) as an outward indication of illness. This context-dependent phenomenon seems to weigh the benefits and costs of eliciting sympathy by indicating sickness versus hiding signs of illness to avoid exposing others to potential infection. In a dynamically social species like humans, non-kin may be as likely to respond to these signs with care as family members, particularly fellow church members.

While these studies suggest a gut-brain-behaviour axis, no studies have examined microbes of the oral cavity in relation to maternal mental health.

Objective: To explore a potential oral-brain-behaviour axis related to maternal mental health.

Low-frequency hearing is critically important for speech and music perception. However, technical and anatomical limitations previously made it difficult to study the mechanics of the low-frequency parts of the cochlea, but this changed with the introduction of optical coherence tomography vibrometry. With this technique, sound-evoked vibration can be measured from the apex of a fully intact cochlea.
