This research focuses on the promising use of esketamine in perinatal depression, a widespread disorder impacting postpartum women's mental health. Despite esketamine's known rapid antidepressant effects, its precise mechanisms are not fully understood. This study integrates clinical and preclinical approaches to explore esketamine's efficacy in treating perinatal depression and its actions associated with TASK-1 potassium channels. A total of298 full-term pregnant women participated in a clinical trial, revealing that esketamine significantly lowers depression scores compared to controls. Alongside, mouse models were used to assess behavioral changes post-treatment, with findings highlighting reduced neuroinflammation and depressive-like symptoms, attributable to modulation via TASK-1 channels. Advanced gene expression analyses and cultured neuronal cell studies corroborated these findings, particularly through the modulation of synaptic plasticity proteins. Thus, esketamine offers a compelling therapeutic avenue for perinatal depression, with its effectiveness linked to specific neural pathways, encouraging further research and potential therapeutic developments.

Background: Perinatal depression has been linked to higher negative affectivity (NA) in children, though the strength of this association is variable. Infant sleep, a known protective factor, may moderate this relationship though this has not been tested.
Objective: To examine whether within-person changes in depressive symptoms across pregnancy and postpartum were linked to child NA, and whether infant sleep duration moderated these effects.

Purpose: Understanding the mechanisms through which poverty influences perinatal depression can provide insight into how to develop interventions to improve maternal mental health. To address this question, we aim to estimate indirect effects of important mediators on the causal relationship between food insecurity and symptoms of postnatal depression.
Methods: We used data from the control arm of the Africa Focus on Intervention Research for Mental health - South Africa (AFFIRM-SA) trial that included pregnant women with perinatal depression.

Postpartum depression (PPD) is a major public health issue, significantly affecting the health and well-being of women and children. Research indicates a strong link between adverse childhood experiences (ACEs) and increased PPD rates. While the Adverse Childhood Experiences Questionnaire (ACE-Q) is widely used for ACE screening, the Childhood Traumatic Events Scale (CTES) may better capture trauma items not covered by the ACE-Q, along with the timing and severity of ACEs.

Background: While genetic factors are important influences on maternal mental health, few studies have used symptom-level analyses to examine how genetic liability is related to the experience of specific mental health problems in mothers. A symptom-level approach can account for disorder heterogeneity and delineate key associations between genetic liabilities and mental health.
Methods: Three waves of data (30 weeks of gestation, 6 and 18 months postpartum) from the Norwegian Mother, Father and Child Cohort Study (MoBa) were used to assess item-level associations between genetic liabilities to depression, anxiety, neuroticism and positive affect, and maternal mental health phenotypes (i.
