Developmental exposure to melamine induces long-term effects on brain and behavior in male rodents. To examine whether this prenatal event damages cognitive function in female offspring, we evaluated the behavioral effects and further attempted to investigate synaptic function. Prenatal melamine exposure (PME) was given by oral treatment to pregnant females through the whole gestational days with 400mg/day/kg bodyweight. On postnatal day (PD) 36, female offspring were assessed for spatial cognition in the Morris Water Maze (MWM) test...

Several lines of evidence indicate that adverse experience in early life may be a triggering factor for disturbances in the brain mitochondrial proteins and lead to the development of depression in adulthood. On the other hand, little is known about the impact of chronic administration of various antidepressant drugs on the brain mitochondria, as a target for the pharmacotherapy of depression. The purpose of our study was to compare the impact of chronic treatment with two antidepressant drugs with different mechanisms of action, a tricyclic antidepressant (TCA), imipramine, and an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class, fluoxetine, on the mitochondria-enriched subproteome profile in the hippocampus of 3-month-old male rats following a prenatal stress procedure (an animal model of depression)...

Depression, anxiety, and stress are common in pregnant women. One of the primary pharmacological treatments for anxiety and depression is the antidepressant fluoxetine (Flx). Maternal stress, depression, and Flx exposure are known to effect neurodevelopment of the offspring, however, their combined effects have been scarcely studied, especially in female offspring. The present study investigated the combined effects of maternal stress during pregnancy and perinatal exposure to Flx on the behaviour of female mice as adults...

The experience of maternal distress in pregnancy is often linked with poorer obstetric outcomes for women as well as adverse outcomes for offspring. Alterations in placental glucocorticoid signalling and subsequent increased fetal exposure to cortisol have been suggested to underlie this relationship. In the current study, 121 pregnant women completed the Perceived Stress Scale, State Trait Anxiety Inventory and Edinburgh Postnatal Depression Scale in the third trimester of pregnancy. Placental samples were collected after delivery...

BACKGROUND: Substantial evidence indicates that perinatal mental disturbances are associated with the risk for negative maternal-newborn outcomes. A neuroendocrine brain-placenta interaction has been described to explain the association between prenatal stress-related disorders and placental abnormalities. Whether these mechanisms may affect the likelihood of mother-to-child transmission (MTCT) of infections has never been investigated. AIMS: To evaluate the role of psychological factors in cytomegalovirus (CMV) MTCT in pregnant women with primary CMV infection...

Intrauterine growth restriction (IUGR) and maternal stress during pregnancy are two compromises that negatively impact neurodevelopment and increase the risk of developing later life neuropsychiatric disorders such as schizophrenia, depression and behavioural disorders. Neurosteroids, particularly allopregnanolone, are important in protecting the developing brain and promoting many essential neurodevelopmental processes. Individually, IUGR and prenatal stress (PS) reduce myelination and neurogenesis within affected fetal brains, however less information is available on the combined effects of these two disorders on the term fetal brain...

BACKGROUND: Recently, studies have begun emphasizing paternal involvement during the perinatal period and its impact on maternal health. However, most studies have assessed maternal perception and focused on adolescents or minority groups in Western countries. Therefore, the current study investigated the association between paternal involvement and maternal postnatal depression and anxiety, along with the effects of maternal job status in the Asian society of Taiwan. METHODS: This study recruited pregnant women in the first trimester of pregnancy as well as their partners on prenatal visits from July 2011 to September 2013 at four selected hospitals in metropolitan areas of Taipei, Taiwan...

BACKGROUND: Childbirth fear is linked with lower labor pain tolerance and worse postpartum adjustment. Empirically validated childbirth preparation options are lacking for pregnant women facing this problem. Mindfulness approaches, now widely disseminated, can alleviate symptoms of both chronic and acute pain and improve psychological adjustment, suggesting potential benefit when applied to childbirth education. METHODS: This study, the Prenatal Education About Reducing Labor Stress (PEARLS) study, is a randomized controlled trial (RCT; n = 30) of a short, time-intensive, 2...

During the last twenty years, in spite of extensive literature regarding the use of SSRIs in pregnancy, confusion still exists as to possible long-term risks of these drugs on the offspring. Possible negative effects relate to neurodevelopmental outcome and association with Autism Spectrum Disorder (ASD). Most neurodevelopmental follow up studies did not find significant cognitive impairment except from some apparently transient, gross motor delay and slight impairment of language abilities. The literature on the possible association of SSRIs with ASD is inconsistent, and if an association exists it is apparently throughout pregnancy...

This study examined the course of antidepressant use, sleep quality, and depression severity from pregnancy through 6-month postpartum in women with and without a depressive disorder during pregnancy. Women (N = 215) were interviewed during pregnancy, 1- and 6-month postpartum. Mixed linear models were used to examine the longitudinal course and inter-relationships for the time-varying variables of antidepressant use, subjective sleep quality, and depression severity. Pregnant women with a depressive disorder who did not use antidepressants had more variable depression severity over time with improvements in depression severity by 6-month postpartum...

One in 7 women experience depression during the prenatal and/or postpartum period. Nonpharmacologic approaches are known to be as effective as pharmacologic therapies for mild to moderate depression. However, for women who suffer from moderate to severe depression, antidepressant therapy may be the best option, in combination with nonpharmacologic approaches. Considering the substantial negative impact of untreated perinatal depression, providers of prenatal care need to be prepared to diagnose depression, prescribe first-line antidepressants, and refer to other professionals...

BACKGROUND: Prenatal anxiety and depression are distressing for the expectant mother and can have adverse effects on her fetus and subsequently, her child. This study aimed to determine whether listening to specially composed songs would be an effective intervention for reducing symptoms of prenatal anxiety and depression. METHODS: Pregnant women were recruited online and randomly assigned to one of two groups: the music group (daily listening to specially composed songs) or control group (daily relaxation) for 12 weeks each...

Prenatal ethanol exposure (PE) leads to increased addiction risk which could be mediated by enhanced excitatory synaptic strength in ventral tegmental area (VTA) dopamine (DA) neurons. Previous studies have shown that PE enhances excitatory synaptic strength by facilitating an anti-Hebbian form of long-term potentiation (LTP). In this study, we investigated the effect of PE on endocannabinoid-mediated long-term depression (eCB-LTD) in VTA DA neurons. Rats were exposed to moderate (3 g/kg/day) or high (6 g/kg/day) level of ethanol during gestation...

Exposure to stress during critical periods in development can have severe long-term consequences, increasing overall risk on psychopathology. One of the key stress response systems mediating these long-term effects of stress is the hypothalamic-pituitary-adrenal (HPA) axis; a cascade of central and peripheral events resulting in the release of corticosteroids from the adrenal glands. Activation of the HPA-axis affects brain functioning to ensure a proper behavioral response to the stressor, but stress-induced (mal)adaptation of the HPA-axis' functional maturation may provide a mechanistic basis for the altered stress susceptibility later in life...

BACKGROUND: Allostatic load (AL) measures the cumulative impact of chronic stress and is associated with adverse health outcomes. A novel scoring system has previously been developed for AL in early pregnancy that is associated with pre-eclampsia. It was hypothesized that AL, as identified by the present model, is associated with psychosocial stressors and, specifically, poor sleep quality. METHODS: Women were selected from a low-risk, community-dwelling study population who enrolled at <15 weeks gestation...

Maternal depressive symptoms influence neurodevelopment in the offspring. Such effects may appear to be gender-dependent. The present study examined contributions of prenatal and postnatal maternal depressive symptoms to the volume and microstructure of the amygdala in 4.5-year-old boys and girls. Prenatal maternal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) at 26 weeks of gestation. Postnatal maternal depression was assessed at 3 months using the EPDS and at 1, 2, 3 and 4...

The pathophysiological underpinnings of neuroprogressive processes in recurrent major depressive disorder (rMDD) are reviewed. A wide array of biochemical processes underlie MDD presentations and their shift to a recurrent, neuroprogressive course, including: increased immune-inflammation, tryptophan catabolites (TRYCATs), mitochondrial dysfunction, aryl hydrocarbonn receptor activation, and oxidative and nitrosative stress (O&NS), as well as decreased sirtuins and melatonergic pathway activity. These biochemical changes may have their roots in central, systemic and/or peripheral sites, including in the gut, as well as in developmental processes, such as prenatal stressors and breastfeeding consequences...

OBJECTIVE: On the basis of self-determination theory, this study investigates longitudinal associations between satisfaction and frustration mothers' basic psychological needs (i.e., autonomy, relatedness, competence) and mothers' postnatal depressive symptoms and early parenting behaviors. METHOD: Participants were 214 women assessed during their pregnancy (Time 1), 4 months after delivery (Time 2), and when the child was 2 years old (Time 3). RESULTS: Results demonstrate effects of prenatal basic psychological needs (needs frustration more specifically) on postnatal depressive symptoms...

Women with major depressive disorder during pregnancy often use selective serotonin reuptake inhibitors (SSRIs) antidepressants. These drugs readily cross the placental barrier and impact the developing fetal brain. Recently, we reported that prenatal fluoxetine (FLX), an SSRI antidepressant drug, altered corticosterone and behavioral responses to stress in female mouse offspring. The present study assessed the effects of prenatal FLX on these responses in males. The results showed that prenatal FLX significantly augmented the corticosterone response to acute stress in young prepubescent mice...
