BACKGROUND: Hypoxia-ischemia (HI) is a major cause of neurological damage in preterm. Pregnancy swimming alters the pup's brain development. We tested the effects of swimming during pregnancy in the very immature rat brain. METHODS: Female Wistar rats (n=12) were assigned to sedentary (SE, n=6) or swimming groups (SW, n=6). From the gestational day 0 (DG0) to GD21 they performed 20 min/daily swimming sessions. HI on postnatal day 3 rat cause sensorimotor and cognitive impairments...

To date, the precise prevalence of co-morbidity of anxiety and depression in the perinatal period is not well known. We aimed to estimate the prevalence of co-morbid anxiety and depression in the antenatal and postnatal periods. Systematic searches of multiple electronic databases were conducted for studies published between January 1950 and January 2016. We included 66 (24 published and 42 unpublished) studies incorporating 162 120 women from 30 countries. Prevalence of self-reported antenatal anxiety symptoms and mild to severe depressive symptoms was 9...

Valproate has been used for over 30years as a first-line treatment for epilepsy. In recent years, prenatal exposure to valproate has been associated with teratogenic effects, limiting its use in women that are pregnant or of childbearing age. However, despite its potential detrimental effects on development, valproate continues to be prescribed at high rates in pediatric populations in some countries. Animal models allow us to test hypotheses regarding the potential effects of postnatal valproate exposure on neurobehavioral development, as well as identify potential mechanisms mediating observed effects...

Both genetic factors and early life adversity play major roles in the etiology of schizophrenia. Our previous studies indicated that social isolation (SI) during early postnatal development leads to several lasting abnormal behavioral and pathophysiological features resembling the core symptoms of some human neuropsychiatric disorders in mice. The glutamate and dopamine hypotheses are tightly linked to the development of schizophrenia. The cross-talk between glutamate N-methyl-D-aspartate acid receptors and dopamine receptors is associated with histidine triad nucleotide binding protein 1 (HINT1), which is correlated with diverse psychiatric disorders...

OBJECTIVE: Women and their infants need special protection in war context, as traumatic events can risk maternal mental and obstetric health and compromise infant development. This prospective study examined, first, how exposure to war trauma is associated with maternal mental health in pregnancy and postpartum, obstetric and newborn health, and infant development. Second, it tested the role of maternal mental health and obstetric risks in mediating between war trauma and infant development...

Evidence has implicated the translocation of commensal Gram-negative bacteria (Gram-B) due to leaky gut in the pathophysiology of depression and physio-somatic symptoms (e.g. fatigue, pain, irritable bowel syndrome, malaise, etc.). In addition, the leaky gut may contribute to immune-inflammatory activation and oxidative stress. This study investigated whether bacterial translocation is associated with perinatal depression and anxiety scores and with prenatal physio-somatic symptoms and immune-inflammatory biomarkers, including the tryptophan catabolite (TRYCAT) pathway...

BACKGROUND: Pregnancy is a significant transition period for women that can be markedly stressful. The presence of elevated depressed mood and anxiety during pregnancy places mothers, fetuses, and neonates at greater risk for developing biological and psychological difficulties. It appears that no general measures of distress currently exist that can be used to screen for both prenatal anxiety and mood. MATERIALS AND METHODS: This study explores the applicability of postpartum distress measure (PDM), a validated general distress postpartum screening tool, in a prenatal sample...

OBJECTIVES: This study was conducted to examine the sexual dimorphic effects of highly palatable food (HPF) access during adolescence on the neurochemistry and depression-/anxiety-like behaviors of rats. METHODS: Male and female Sprague-Dawley pups had free access to chocolate cookie rich in fat (HPF) from postnatal day 28 in addition to ad libitum chow, and the control groups received only chow. The food conditions were continued throughout the entire experimental period, and the neurochemical and behavioral measurements were performed during young adulthood...

There is debate about the relative importance of timing of stressful events prenatally and over the life course and risk for subsequent depressive/anxious illness. The aim of this study was to examine the relative roles of prenatal stress and postnatal stress trajectories in predicting depression and anxiety in early adulthood in males and females. Exposure to life stress events was examined in the Western Australian Pregnancy Cohort (Raine) Study during pregnancy and ages 1, 2, 3, 5, 8, 10, 14, and 17 years...

In adult rats, access to a palatable diet can buffer against the effects of stressors. Approximately 10% of all adolescents are repeatedly victimized by their peers raising the possibility that palatable food consumption may be relevant to this developmental window. This study assessed the long-term impact of juvenile social defeat exposure on anxiety and depressive-like behavior and whether daily limited access to a palatable diet moderated these behavioral consequences. We also investigated the impact of the palatable diet on behavior during the defeat sessions...

BACKGROUND: Poor perinatal maternal mental health has been linked with negative outcomes on early child development; however, the importance of maternal personality has been neglected thus far. We aimed to examine the effects of antenatal and postnatal maternal mental health, including assessment of maternal personality characteristics, on child neuropsychological and behavioral development at preschool years in a population based mother-child cohort (Rhea Study) in Crete, Greece. METHOD: Self-reported measures of maternal depression (EPDS), trait anxiety (STAI-Trait) and personality traits (EPQ-R) were assessed in a sample of 288 women at 28-32 weeks of gestation...

It is well established that maternal undernutrition and micronutrient deficiencies can lead to altered development and behaviour in offspring. However, few studies have explored the implications of maternal Mg deficiency and programmed behavioural and neurological outcomes in offspring. We used a model of Mg deficiency (prior to and during pregnancy and lactation) in CD1 mice to investigate if maternal Mg deficiency programmed changes in behaviour and NMDAR subunit expression in offspring. Hippocampal tissue was collected at postnatal day 2 (PN2), PN8, PN21 and 6 months, and protein expression of NMDAR subunits GluN1, GluN2A and GluN2B was determined...

Brain development is a complex process regulated by genetic programs and activity-dependent neuronal connectivity. Anesthetics profoundly alter neuronal excitability, and anesthesia during early brain development has been consistently associated with neuroapoptosis, altered synaptogenesis, and persistent behavioral abnormalities in experimental animals. However, the depth, and even more the duration and developmental time point(s) of exposure to anesthesia determine the neuropathological and long-term behavioral consequences of anesthetics...

There is increasing concern about potential long-term effects of antibiotics on children's health. Epidemiological studies have revealed that early-life antibiotic exposure can increase the risk of developing immune and metabolic diseases, and rodent studies have shown that administration of high doses of antibiotics has long-term effects on brain neurochemistry and behaviour. Here we investigate whether low-dose penicillin in late pregnancy and early postnatal life induces long-term effects in the offspring of mice...

Objective This study aimed to assess the possible association of high breast milk sodium levels with postpartum depression and anxiety. Methods A total of 150 mothers and their healthy, exclusively breastfed newborns aged 8 to 15 days were recruited. Mothers were asked to complete scales for evaluation of postnatal depression and anxiety following an interview for consent and sociodemographic data collection. Breast milk samples were obtained to measure sodium and potassium (K) levels. Results Forty-nine mothers had higher than expected breast milk Na concentrations and a high Na/K ratio...

In this longitudinal prospective observational study performed at a tertiary perinatal referral centre, we aimed to assess maternal distress in pregnancy in women with ultrasound findings of fetal anomaly and compare this with distress in pregnant women with normal ultrasound findings. Pregnant women with a structural fetal anomaly (n = 48) and normal ultrasound (n = 105) were included. We administered self-report questionnaires (General Health Questionnaire-28, Impact of Event Scale-22 [IES], and Edinburgh Postnatal Depression Scale) a few days following ultrasound detection of a fetal anomaly or a normal ultrasound (T1), 3 weeks post-ultrasound (T2), and at 30 (T3) and 36 weeks gestation (T4)...

BACKGROUND: To date, there have been few studies of DMDD examining the risk factors during gestation and during the first years of life. We assessed the perinatal and postnatal risk factors associated with the occurrence of disruptive mood dysregulation disorder (DMDD) by 11 years of age. METHODS: Prospective longitudinal study. Mothers completed a standardized questionnaire shortly after childbirth. We used the Development and Well-Being Assessment, administered to the mothers or legal guardians, to identify DMDD among the 11-year-old subjects...

Hypertension is one of the most common diseases in humans, and there is a special concern on the consequences of maternal hypertensive conditions for the health of newborns. An inherited stress-induced arterial hypertension (ISIAH) rat strain has been selected but only a few studies have addressed behavior in these rats. Body weight, neurodevelopmental reflexes, and neuronal density in the hippocampus were compared in ISIAH and normotensive WAG rats during their suckling period. Systolic and diastolic blood pressure (SBP, DBP), adult rat performance in the open field (OF), elevated plus maze (EPM), and novel object recognition (NOR) tests were evaluated at the age of 12-14weeks old...

Anxiety symptoms occur in a large portion of Alzheimer's disease (AD) patients. ApolipoproteinE-4 (ApoE ε4 allele), a risk factor for AD, has been recognized as an important contributor to psychiatric disorders. In the present study, we aimed to investigate the corticosterone level in relation to anxiety-like behavior changes in transgenic male mice with different glial fibrillary acidic protein (GFAP)-ApoE isoforms. GFAP-ApoE4 transgenic mice aged 3 months showed higher anxiety-like behavior in open field, light-dark box and elevated plus maze tasks compared with that of age-matched GFAP-ApoE3 mice...

Emotion regulation is essential to cognitive, social, and emotional development and difficulties with emotion regulation portend future socioemotional, academic, and behavioral difficulties. There is growing awareness that many developmental outcomes previously thought to begin their development in the postnatal period have their origins in the prenatal period. Thus, there is a need to integrate evidence of prenatal influences within established postnatal factors, such as infant temperament and maternal sensitivity...
