BACKGROUND: Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain, and is widely used as a form of pain relief in labour. However, there are concerns about unintended adverse effects on the mother and infant. This is an update of an existing Cochrane Review (Epidural versus non-epidural or no analgesia in labour), last published in 2011. OBJECTIVES: To assess the effectiveness and safety of all types of epidural analgesia, including combined-spinal-epidural (CSE) on the mother and the baby, when compared with non-epidural or no pain relief during labour...

Nurturing behavior may be critically influenced by the interplay of different hormones. The neuropeptide oxytocin is known to promote maternal behavior and its reduction has been associated with postpartum depression risk and child neglect. Contrariwise, the observed decrease in testosterone level during early parenthood may benefit caretaking behavior, whereas increased testosterone may reduce attention to infants. Here we used functional magnetic resonance imaging to investigate the interactive influence of testosterone and oxytocin on selective attention to and neural processing of the baby schema (BS)...

The past decades have witnessed an explosion of knowledge on brain structural abnormalities in schizophrenia and depression. Focusing on the hypothalamus, we try to show how postmortem brain microscopy has contributed to our understanding of mental disease-related pathologic alterations of this brain region. Gross anatomical abnormalities (volume changes of the third ventricle, the hypothalamus, and its nuclei) and alterations at the cellular level (loss of neurons, increased or decreased expression of hypothalamic peptides such as oxytocin, vasopressin, corticotropin-releasing hormone, and other regulatory factors as well as of enzymes involved in neurotransmitter and neuropeptide metabolism) have been reported in schizophrenia and/or depression...

Sexual dysfunction is a common cause of selective serotonin reuptake inhibitor (SSRI) withdrawal. Various studies indicate that decreased oxytocin is involved as a mechanism of delayed ejaculation induced by SSRIs. The aim of the present pilot study was to evaluate and compare sexual dysfunction and oxytocin levels in women being treated with either fluoxetine or citalopram. Thirty-nine women with the diagnosis of major depressive disorder were enrolled in the study. A baseline blood sample was collected and each participant was given either fluoxetine 20 mg/d or citalopram 20 mg/d...

Body dysmorphic disorder is a challenging disorder that manifests as erroneously perceived flaws in one's physical appearance and repetitive behaviors in response to appearance concerns. This disorder is also frequently comorbid with other psychiatric disorders, including major depressive disorder and autism spectrum disorder. It is currently understood to arise from a combination of biological, psychological, and environmental factors. Treatment of body dysmorphic disorder typically consists of a combination of pharmacotherapy and cognitive behavioral therapy...

To date, no medication is proven to be effective in treating core symptoms of autism spectrum disorder (ASD). Psychotropic medications are widely used to target emotional and behavioural symptoms in ASD. This article reviewed evidence for pharmacotherapy, novel therapeutic agents, and Complementary and Alternative Medicine (CAM) in children and adolescents with ASD. Currently, only risperidone and aripiprazole have been approved by the US Food and Drug Administration (FDA) for treatment of irritability associated with ASD in children and adolescents...

Lei Xiao, Michael F Priest, Yevgenia Kozorovitskiy
The experience of rewarding or aversive stimuli is encoded by distinct afferents to dopamine (DA) neurons of the ventral tegmental area (VTA). Several neuromodulatory systems including oxytocin regulate DA neuron excitability and synaptic transmission that process socially meaningful stimuli. We and others have recently characterized oxytocinergic modulation of activity in mouse VTA DA neurons, but the mechanisms underlying oxytocinergic modulation of synaptic transmission in DA neurons remain poorly understood...

The medial nucleus of the amygdala (MeA) plays a pivotal role in a variety of mammalian social behaviors. Specifically, activity of the hypothalamic pro-social neuropeptide oxytocin in the MeA was shown to be crucial for social recognition memory. The MeA is also a hub of neuroendocrine activity and expresses a large number of receptors of neuropeptides and hormones. These include oxytocin receptor, estrogen receptor alpha and corticotropin-releasing factor (CRF) receptor type 2 (CRFR2). In a previous study we found that intracerebroventricular (ICV) oxytocin application to anesthetized rats promotes long-term depression (LTD) of the MeA response to electrical stimulation of its main sensory input, the accessory olfactory bulb (AOB)...

Objective: The objective of this study was to investigate the factors associated with depression, including serum oxytocin (OXT) levels, disease activity, activities of daily living (ADL), and quality of life (QOL), and their effects on rheumatoid arthritis (RA). Methods: This study included 42 RA patients who received treatment with a biological agent. We measured the following variables before and after 6 months of treatment: baseline characteristics, including age, sex, disease duration, smoking, and body mass index (BMI); prednisolone and methotrexate dose; serum level of matrix metalloproteinase-3 (MMP-3); erythrocyte sedimentation rate (ESR); and C-reactive protein (CRP) level...

BACKGROUND: In animals, adverse early experience alters oxytocinergic and glucocorticoid activity and maternal behavior in adulthood. This preliminary study explored associations among childhood trauma (loss of a parent or sexual abuse in childhood), maternal self-efficacy, and leukocyte gene expression (mRNA) of oxytocin and glucocorticoid receptors (OXTR and NR3C1) in mothers of infants. METHODS: 62 mothers (20 with early life trauma) with healthy 3-month old infants reported maternal self-efficacy, depression, infant temperament, and overall social support; the effects of early trauma on these measures were assessed...

Background: Despite its worldwide high occurrence, the obscurity regarding the description, epidemiology and management of premature ejaculation remains provocative. It is well established that male premature ejaculatory dysfunction is an increasing problem due to spontaneous ejaculation across a variety of general and clinical subjects. The main goal of this study was to determine the relationships between trinucleotide repeats of the androgen receptor (AR), sex steroids, and pituitary hormones with sexual function in men with type 2 diabetes mellitus (DM) and reported with acquired premature ejaculation (PE)...

INTRODUCTION: Oxytocin (OT) is a well-known neuropeptides which together with vasopressin, melatonin, insulin and other hormones can alter both behavior and physiological or neuronal functions. This growing interest on OT roles is also based on the demonstrated beneficial effects as a stress reliever and a social bonding agent. The association between old age and OT was only vaguely studied. Little or few is known on the effect of the OT hormone on the old body. Hereby, we present our preliminary results in the research on behavioral changes regarding the intraperitoneal administration of OT in aged rats...

The increasing prevalence of postnatal anxiety highlights the need for summarizing the recent research on this condition to inform screening and intervention efforts. This narrative review of the literature was derived from a search on PubMed and PsycINFO for papers published since 2010. The demographic risk factors for postnatal anxiety include being a young mother, having more education and being employed. Childbirth risk factors include being primiparous in one sample and multiparous in another, caesarean delivery, fear of the birth and of death during delivery, lack of control during labor, low self-confidence for the delivery and the delivery staff, and premature delivery...

Background: Child maltreatment (CM) and attachment experiences are closely linked to alterations in the human oxytocin (OXT) system. However, human data about oxytocin receptor (OXTR) protein levels are lacking. Therefore, we investigated oxytocin receptor (OXTR) protein levels in circulating immune cells and related them to circulating levels of OXT in peripheral blood. We hypothesized reduced OXTR protein levels, associated with both, experiences of CM and an insecure attachment representation. Methods: OXTR protein expressions were analyzed by western blot analyses in peripheral blood mononuclear cells (PBMC) and plasma OXT levels were determined by radioimmunoassay (RIA) in 49 mothers...

BACKGROUND: While maternal depression is known to carry long-term negative consequences for offspring, very few studies followed children longitudinally to address markers of resilience in the context of maternal depression. We focused on oxytocin (OT) and mother-child synchrony - the biological and behavioral arms of the neurobiology of affiliation - as correlates of resilience among children of depressed mothers. METHOD: A community birth-cohort was recruited on the second postbirth day and repeatedly assessed for maternal depression across the first year...

The infant's psycho-physiological regulatory system begins to develop prenatally and continues to mature during the postnatal period. Temperament is a construct comprising tonic individual differences in dispositional physiological and behavioural reactions as well as an evolving ability to regulate to environmental conditions. Theoretical models and research have shown that neurohormonal and -physiological factors contribute to individual development and impact infant behaviours as well as the developing regulatory system...

Although the neurohypophyseal hormones vasopressin and oxytocin are mostly known for their role respectively in antiduresis the former and in labour, lactation and maternal behavior the latter, both might exert widespread influences either on emotion and cognition in healthy subjects, showing some gender-related differences. They interact one each other facilitating shifts between positive socially- oriented and defensive states. In fact, vasopressin amplifies the reactivity to stressors showing also beneficial effects on attention, verbal learning as well as memory, whereas oxytocin reduces the amplitude of the stress response, improves emotion processing, and can play a negative effect on memory and verbal learning in healthy individuals...

The aim of this study was to investigate placental DNA methylation of the oxytocin receptor gene (OXTR) in women with depression in pregnancy. We also explored the role of antidepressant medication in pregnancy on placental OXTR methylation. Data were obtained from 239 women in the Mercy Pregnancy and Emotional Wellbeing Study (MPEWS), a selected pregnancy cohort. Current depressive disorders were diagnosed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID-IV)...

There is increasing recognition that women have a higher prevalence of certain psychiatric illnesses, and a differential treatment response and course of illness compared to men. Additionally, clinicians deal with a number of disorders like premenstrual syndrome, premenstrual dysphoric disorder, and postpartum depression, which affect women specifically and for which treatment and biological pathways are still unclear. In this article we highlight recent research which suggests that different biological mechanisms may underlie sex differences in responsiveness to stress...

BACKGROUND: Childhood and adulthood traumatic experiences negatively impact maternal-infant bonding and increase risk of postpartum depression (PPD). Lower oxytocin levels have also been associated with PPD and compromised mother-infant bonding. Despite advances in these areas of investigation, much of the research has not included Latinas, who are important because they have high rates of fertility, traumatic events, and PPD. METHODS: To address gaps identified in the literature, we explored associations between traumatic life events, PPD, and bonding subscale scores (e...
