INTRODUCTION: Increased prevalence of nicotine dependence among individuals suffering from posttraumatic stress disorder (PTSD) is well established. However, there are limited studies on the prevalence of smoking during pregnancy in relation to prepregnancy history of trauma exposures and active PTSD symptoms during pregnancy. Prenatal smoking has been implicated in a host of negative outcomes for mother and baby. Given maternal and fetal risk, it is critical to define predictors of continued cigarette smoking during pregnancy...

OBJECTIVE: The effects of prenatal yoga on biological indicators have not been widely studied. Thus, we compared changes in stress and immunity salivary biomarkers from 16 to 36 weeks' gestation between women receiving prenatal yoga and those receiving routine prenatal care. DESIGN: For this longitudinal, prospective, randomized controlled trial, we recruited 94 healthy pregnant women at 16 weeks' gestation through convenience sampling from a prenatal clinic in Taipei...

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...

<i>Prenatal stress-induced neurobehavioral deficits observed in offspring are multifactorial, including oxidative stress in the developing brain. The time by which the developing brain acquires self-defense against oxidative stress is not clear. Hence in the present study we aimed to evaluate the brain antioxidant status during different developing periods. Further the study also evaluates the role of the glutathione precursor, N-acetyl cysteine (NAC) on the brain antioxidant status. Pregnant rats were subjected to restraint stress during an early or late gestational period...

The primary objective in modern obstetrics and prenatal diagnosis is to predict risks of congenital abnormalities. The aim of the research was to assess the correlation between selected oxidative stress biomarkers with the risk of foetal chromosomal aberration evaluated at the first trimester screening. A series of studies show that balanced free radical activity and oxidative homeostasis are essential for proper bodily growth and function. Reactive oxygen species (ROS) may be one of the factors associated with disruption of cell cycle and tissue development, thus leading to developmental abnormalities...

We experienced a case of advanced maternal age in which a fetus was found to be positive for trisomy 18 at re-examination following indeterminate non-invasive prenatal genetic testing (NIPT), the amniotic fluid chromosomal test revealed a normal karyotype, and confined placental mosaicism (CPM) was observed in an SNP microarray analysis of the placenta. The child was born with no defects or complications. In the present case, the result of the original NIPT at week 15 of pregnancy was indeterminate and the subsequent re-examination result was positive; since the definitive normal diagnosis was not reported until the latter half of week 21, the pregnant patient was subjected to psychological stress for a long period of time...

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...

Reliable human data on the effects of prenatal exposure to ionizing radiation are largely based on high-dose exposures. Exposure to low doses may produce effects that are not easily observable at birth, and may persist over the course of the offspring's postnatal life. This is important when considering fetal programing, a phenomenon characterized by changes in offspring phenotype due to a stress experienced in utero. In this review, we briefly summarize the known effects of both high- and low-dose exposure to ionizing radiation during pregnancy in humans...

This study was to determine the impact of maternal exposure to di-n-butyl phthalate (DBP) on renal development and fibrosis in adult offspring. Pregnant rats received DBP at a dose of 850 mg/kg BW/day by oral perfusion during gestational days 14-18. In DBP exposed newborn offspring, gross observation and histopathological examination revealed the dysplasia of kidney. The expression of genes related to renal development was also changed. In DBP exposed adult offspring, histopathological examination and Masson's trichrome staining revealed the pathological changes of renal fibrosis...

INTRODUCTION: The aim of this study was to determine the presence and morphology of the anterolateral ligament (ALL) of the knee in a sample of fetuses. We hypothesized that the ALL is present in sample fetuses and its origin is not related to repetitive stresses throughout life. MATERIAL & METHODS: Forty fresh-frozen knees from cadaveric fetuses were dissected using a standard technique. The ALL and other structures in the anterolateral compartment of the knee were identified...

Neonatal pulmonary hypertension (PHN) is a lethal progressive disease that occurs in prenatal circulatory transition. Mechanical wall strain caused by cardiac pulsation integrates with hypoxia to generate rapidly progressive myocyte cytoskeleton disassembly and failure to exert force generation. The physiological responses to such an interaction have not been investigated. The persistent phenotype does not respond to traditional vasodilator therapy; hence, there is a need for new treatment strategies to improve the morbidity and mortality outcomes...

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...

Introduction: Most women who quit smoking during pregnancy will relapse postpartum. Interventions for sustained postpartum abstinence can benefit from understanding prenatal characteristics associated with treatment response. Given that individuals with psychiatric disorders or elevated depressive symptoms have difficulty quitting smoking and that increases in depressive symptoms prenatally are common, we examined the relevance of psychiatric diagnoses, prenatal depressive symptoms, and stress to postpartum relapse prevention intervention response...

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...

Assessing fishing effects on chondrichthyan populations has predominantly focused on quantifying mortality rates. Consequently, sub-lethal effects of capture stress on the reproductive capacity of chondrichthyans are largely unknown. We investigated the reproductive consequences of capture on pregnant southern fiddler rays (Trygonorrhina dumerilii) collected from Swan Bay, Australia, in response to laboratory-simulated trawl capture (8 h) followed immediately by air exposure (30 min). Immediately prior to, and for up to 28 days post trawling, all females were measured for body mass (BM), sex steroid concentrations (17-β estradiol, progesterone, testosterone) and granulocyte to lymphocyte (G:L) ratio...

Telomere length (TL) is a marker of biological aging, and numerous studies have shown associations between TL and somatic or psychiatric disorders. Research also indicates an association between maternal stress during pregnancy and TL in the offspring. The present study investigated possible associations between TL and: (1) maternal perceived stress during pregnancy; (2) a maternal life-time history of psychiatric disorder (life-time PD); and (3) paternal age. TL was analysed in 319 newborns and 318 mothers from a predominantly Caucasian sample (n=273 Caucasian newborns and n=274 Causasian mothers)...

The endoplasmic reticulum (ER), comprises 60% of the total cell membrane and interacts directly or indirectly with several cell organelles i.e., Golgi bodies, mitochondria and proteasomes. The ER is usually associated with large numbers of attached ribosomes. During evolution, ER developed as the specific cellular site of synthesis, folding, modification and trafficking of secretory and cell-surface proteins. The ER is also the major intracellular calcium storage compartment that maintains cellular calcium homeostasis...

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...
