Major life events require psychological adaptations and can be accompanied by brain structural and functional changes. The goal of the current study was to investigate the association of personal growth initiative (PGI) as a form of proactive coping strategy before childbirth, with gray matter volume after delivery. Childbirth is one of the few predictable major life events, which, while being one of the most positive experiences for many, is also accompanied by multidimensional stress for the mother. Previous research has shown that high stress is associated with reductions in gray matter volume in limbic cortices as well as the prefrontal cortex (PFC)...

An increasing number of studies indicate that the chemokine system may be the third major communication system of the brain. Therefore, the role of the chemokine system in the development of brain disorders, including depression, has been recently proposed. However, little is known about the impact of the administration of various antidepressant drugs on the brain chemokine - chemokine receptor axis. In the present study, we used an animal model of depression based on the prenatal stress procedure. We determined whether chronic treatment with tianeptine, venlafaxine, or fluoxetine influenced the evoked by prenatal stress procedure changes in the mRNA and protein levels of the homeostatic chemokines, CXCL12 (SDF-1α), CX3CL1 (fractalkine) and their receptors, in the hippocampus and frontal cortex...

Emerging research in epigenetics has shown that there is variability in how environmental exposures "get under the skin" through mechanisms like DNA methylation to influence gene expression that may lead to differential adaptations to stress. This is the first study to examine prospectively the relationship between DNA methylation at birth and resilience to prenatal environmental stressors in several domains (conduct, hyperactivity, emotional problems, and global symptomatology) in middle childhood. We focused on DNA methylation in the vicinity of the oxytocin receptor (OXTR) gene as it has been previously associated with impairments in social-cognitive processes that may underlie a wide range of childhood psychopathology...

The quality of prenatal maternal mental health, from psychological stress and depressive symptoms to anxiety and other nonpsychotic mental disorders, profoundly affects fetal neurodevelopment. Despite the evidence for the influence of positive mental well-being on health, there is, to our knowledge, no research examining the possible effects of positive antenatal mental health on the development of the offspring. Using exploratory bifactor analysis, this prospective study (n = 1,066) demonstrated the feasibility of using common psychiatric screening tools to examine the effect of positive maternal mental health...

We examined the prospective associations of objective and subjective measures of stress during pregnancy with infant stress reactivity and regulation, an early-life predictor of psychopathology. In a racially and ethnically diverse low-income sample of 151 mother-infant dyads, maternal reports of stressful life events (SLE) and perceived stress (PS) were collected serially over gestation and the early postpartum period. Infant reactivity and regulation at 6 months of age was assessed via maternal report of temperament (negativity, surgency, and regulation) and infant parasympathetic nervous system physiology (respiratory sinus arrhythmia [RSA]) during the Still Face Paradigm...

Aging is a progressive internal physiological deterioration of the organism, leading to the occurrence of age-related lethal diseases. It has become a major societal challenge to understand the processes that drive aging and to develop rational pharmacological agents and dietary approaches to fight against age-related deterioration and diseases. Interestingly, several lines of evidence highlight an influence of the developmental period on the risk of age-related diseases later in life. This field is known as the developmental origins of health and disease...

The early environment has a major impact on the developing embryo, fetus and infant. Parental adversity (maternal and paternal) and glucocorticoid exposure prior to conception and during pregnancy have profound effects on the development and subsequent function of the hypothalamic-pituitary-adrenal (HPA) axis and related behaviours. These effects are species-, sex- and age-specific, and depend on the timing and duration of exposure. The impact of these early exposures can extend across multiple generations, via both the maternal and paternal lineage, and recent studies have begun to determine the mechanisms by which this occurs...

Adolescent pregnant women are at greater risk for nutritional deficits, stress, and depression than their adult counterparts, and these risk factors for adverse pregnancy outcomes are likely interrelated. This study evaluated the prevalence of nutritional deficits in pregnant teenagers and assessed the associations among micronutrient dietary intake, stress, and depression. One hundred and eight pregnant Latina adolescents completed an Automated Self-Administered 24-hour dietary recall (ASA24) in the 2nd trimester...

Thyroid hormones (THs) are essential for establishing layered brain structures, a process called corticogenesis, by acting on transcriptional activity of numerous genes. In humans, deficiency of the monocarboxylate transporter 8 (MCT8), involved in cellular uptake of THs prior to their action, results in severe neurological abnormalities, known as the Allan-Herndon-Dudley Syndrome. While the brain lesions predominantly originate prenatally, it remains unclear how and when exactly MCT8 dysfunction affects cellular processes crucial for corticogenesis...

Over the past several decades, prenatal testing for fetal anomalies has become standard across the developed world. Most women who learn of a severe anomaly during pregnancy elect to terminate. The authors reviewed ten studies which examined the psychological sequelae of pregnant women following prenatal diagnoses of severe life limiting conditions. Based on the available data, the authors found evidence that women who abort due to a poor prenatal diagnosis are at higher risk of post-traumatic stress and depression than women who continue with pregnancy...

To investigate the possible developmental programming, we analyzed the effects of maternal and postnatal low dose alpha-cypermethrin exposure on metabolic and redox parameters in the offspring. Postnatal changes in plasma biochemical parameters and plasma and tissue oxidative stress markers were determined in offspring of dams fed standard chow or diet containing alpha cypermethrin at 1.50mg/kg/day during gestation and lactation, weaned on to standard chow or on treated diet until adulthood (5months). Our results showed that exposure to alpha cypermethrin induced a significant reduction in body weight, food intake and metabolic alterations such as an increase in plasma glucose, triglyceride, urea, creatinine and AST levels in both postnatal and prenatal/postnatal treated female and male rats...

BACKGROUND: Prenatal stress is associated with altered fetal and infant development. Previous studies have suggested that these effects may be mediated in part via altered functioning of placental enzymes and receptors involved in the HPA-axis, including the glucocorticoid receptor (NR3C1) and HSD11B2, the enzyme which metabolises cortisol. However, previous studies have not examined the potential ethnicity effects on these associations. This study aimed to characterise the association between maternal prenatal stress and placental genes expression and subsequently, any potential effect of maternal ethnicity...

OBJECTIVE: Respiratory sinus arrhythmia (RSA) is a parasympathetic-mediated biomarker of self-regulation linked to lifespan mental and physical health outcomes. Intergenerational impacts of mothers' exposure to prenatal stress have been demonstrated, but evidence for biological embedding of maternal preconception stress, including adverse childhood experiences (ACEs), on infant RSA is lacking. We examine the independent effects of maternal ACEs and prenatal stress on infant RSA, seeking to broaden the understanding of the earliest origins of mental and physical health risk...

BACKGROUND: Prenatal maternal stress exposure has been linked to sub-optimal developmental outcomes in toddlers, while maternal emotional availability is associated with better cognitive and language abilities. It is less clear whether early care-giving relationships can moderate the impact of prenatal stress on child development. The current study investigates the impact of stress during pregnancy resulting from the Queensland Floods in 2011 on toddlers' cognitive and language development, and examines how maternal emotional availability is associated with these outcomes...

We previously demonstrated thatprenatal caffeine exposure (PCE) suppressed fetal adrenal steroidogenesis and resulted in developmental programming changes in offspring rats. However, whether these changes play a role in adrenal corticosterone synthesis under high-fat diet (HFD) and unpredictable chronic stress (UCS) remains unknown. In present study, rat model was established by PCE (120 mg/kg.d), and male offspring were provided normal diet or HFD after weaning. At postnatal week 21, several rats fed HFD were exposed to UCS for 3 weeks and sacrificed...

Ethanol is the most important teratogen agent in humans. Prenatal alcohol exposure can lead to a wide range of adverse effects, which are broadly termed as Foetal Alcohol Spectrum Disorder (FASD). Socioeconomic status, ethnicity, differences in genetic susceptibility related to ethanol metabolism, alcohol consumption patterns, obstetric problems, maternal nutrition, stress, and other co-administered drugs are all factors that may influence FASD manifestations. Recently, much attention has been paid to the role of nutrition as a protective factor against alcohol teratogenicity...

The current study examined the moderating role of social support in the association between prenatal maternal stress (PNMS) and childhood body mass index (BMI) in the context of the Iowa floods of 2008. In addition, the mediating role of offspring birthweight was examined in the association between PNMS and childhood BMI. We recruited women from eastern Iowa who were pregnant in 2008 when disastrous floods occurred. Self-report measures of PNMS and cognitive appraisal of the flood's consequences were obtained shortly after the disaster...

Prenatal development constitutes a critical time for shaping adult behaviour and may set the stage for vulnerability to disease later in life. A wealth of information from humans as well as from animal research has revealed that exposure to hostile conditions during gestation may result in a series of coordinated biological responses aimed at enhancing the probability of survival, but could also increase the susceptibility to mental illness. Prenatal stress has been linked to abnormal cognitive, behavioural and psychosocial outcomes both in animals and in humans, but the underlying molecular and physiological mechanisms remain largely unknown...
