Implications of childhood adversity for women's perinatal sleep quality and depressive symptoms over time: A serial mediation model.

This study sought to examine the effects of childhood adversity on the longitudinal associations between perinatal sleep quality and depressive symptoms, and to determine the prospective associations between these constructs over time. A cross-lagged autoregressive model was used to examine the longitudinal association between sleep quality and depressive symptoms at four points during the perinatal period: 18 and 32 weeks of pregnancy, and 6 and 12 weeks postpartum. Longitudinal mediation models were used to examine whether sleep quality or depressive symptoms mediated the effects of childhood adversity on these symptoms.

An integrative review of factors and interventions affecting the well-being and safety of nurses during a global pandemic.

Background: Nurses experienced physical and mental exhaustion during the COVID-19 pandemic. Understanding the impact of the pandemic on nurses and effective strategies to support them is critical for increasing nurse resilience and reducing burnout.

Aims: The aims of this study were (1) to synthesize the literature examining how factors associated with the COVID-19 pandemic affected the well-being and safety of nurses (2) and to review interventions which may promote nurse mental health during crises.

Integrative Review of Early Life Adversity and Cortisol Regulation in Pregnancy.

Objective: To synthesize published findings on the relationship between early life adversity and hypothalamic-pituitary-adrenal axis cortisol parameters in pregnant women.

Data Sources: We searched PubMed, CINAHL, and PsycINFO databases using variants and combinations of the keywords early life adversity, pregnancy, hypothalamic-pituitary-adrenal axis, and cortisol.

Study Selection: We selected articles that included pregnant participants, included measures of cortisol and early life adversity, were published in English in a peer-reviewed journal, and were of sufficient methodologic quality.

Early life adversity and depressive symptoms predict cortisol in pregnancy.

Evidence suggests that exposure to early life adversity (ELA) programs the hypothalamic-pituitary-adrenal (HPA) axis to influence responses to later adversity and predisposes women to depression. However, few studies have examined whether ELA moderates the HPA cortisol response to adulthood adversity and depressive symptoms in pregnant women. The aims of this study were to determine (a) whether ELA, adulthood adversity, and depressive symptoms differentially predict patterns of cortisol and (b) whether ELA moderates the relationship of adulthood adversity or depressive symptoms to cortisol.

Interleukin-17A and Chronic Stress in Pregnant Women at 24-28 Weeks Gestation.

Background: Allostatic load (AL) is a biopsychosocial model that suggests chronic psychosocial stress leads to physiological dysregulation and poor outcomes. The purpose of this study was to examine AL in pregnant women operationalized using proinflammatory cytokines and psychosocial indicators and perinatal outcomes.

Objectives: The aim of the study was to identify relationships between circulating cytokines/chemokines and the Prenatal Distress Questionnaire, the Maternal Antenatal Attachment Scale, the Emotional Quotient Inventory, the Life Experiences Scale, and demographics in pregnant women.

Are Heart Failure and Coronary Artery Bypass Surgery Patients Meeting Physical Activity Guidelines?

Purpose: The purpose of this study was to describe subjective and objective physical activity (PA) levels of two groups of cardiovascular patients who were either post-coronary artery bypass graft (CABG) surgery or diagnosed with heart failure (HF).

Design: A descriptive comparative design was used for this secondary analysis of data from two prior studies.

Methods: A convenience sample of 62 outpatients was used to examine PA objectively (Actiheart accelerometer) and subjectively (PA interview).
