Background Social support is highly valued and beneficial for women, especially after childbirth. The objective was to examine the differences of social support reported among teen, optimal age, and advanced age women, and to identify the characteristics associated with social support separately for each age group. Methods This was a cross-sectional analysis of the National Longitudinal Survey of Children and Youth. Primiparous women with infants were grouped into: teen (15-19 years), optimal age (20-34 years), and advanced age (35 years and older)...

This study aimed to establish a method for the selective amplification of cell-free fetal DNA (cffDNA) in maternal plasma and preserve the integrity of DNA fragments during amplification, thereby providing a sufficient amount of cffDNA to meet the requirement of routine non-invasive prenatal testing. We amplified DNA molecules in a one-reaction system without considering their particular sequences and lengths (overall amplification) by using PCR-based enrichment. We then modified PCR conditions to verify the effect of denaturation temperature on DNA amplification on various lengths of DNA (selective overall amplification)...

Offspring of murine dams chronically fed a protein-restricted diet have an increased risk for metabolic and neurobehavioral disorders. Previously we showed that adult offspring, developmentally exposed to a chronic maternal low-protein (MLP) diet, had lower body and hind-leg muscle weights and decreased liver enzyme serum levels. We conducted energy expenditure, neurobehavioral and circadian rhythm assays in male offspring to examine mechanisms for the body-weight phenotype and assess neurodevelopmental implications of MLP exposure...

BACKGROUND: Lower socioeconomic status (SES) and environmental tobacco smoke (ETS) exposure are both associated with poorer disease outcomes in cystic fibrosis (CF), and children with low SES are disproportionately exposed to ETS. We analyzed a large cohort of young children with CF to distinguish the impact of SES and ETS on clinical outcomes. METHODS: The Early Pseudomonas Infection Control Observational study enrolled Pseudomonas-negative young children with CF <13 years of age...

Predation is usually the primary cause of infant death among ungulate species, with the annual variation in the survival of neonates over their first summer a major factor in the population dynamics of many ungulates. Consequently, the maternal rearing strategy of a species is crucial for its reproductive success. Since the roles mothers and fawns play in the implementation of antipredator strategies in hider species have been poorly understood until now, this paper considers this behavior in the goitered gazelle, which is a typical hider species...

BACKGROUND: Mounting evidence indicates that children who experience abuse and neglect are prone to chronic diseases and premature mortality later in life. One mechanistic hypothesis for this phenomenon is that early life adversity alters the expression or functioning of the glucocorticoid receptor (GR) throughout the course of life and thereby increases sensitivity to inflammatory stimulation. An exaggerated pro-inflammatory response is generally considered to be a key cause of postoperative cognitive dysfunction (POCD)...

BACKGROUND: All stages of development of alcohol use disorder (AUD) have not been equally studied. While initiation of drinking has been given considerable attention, other stages have not been as thoroughly investigated. It is not clear whether the same factors are associated consistently across early and late transitions in AUD involvement. High-risk family samples that are enriched for AUD vulnerability and transitions in AUD development offer an opportunity to examine influences across multiple stages of AUD development...

BACKGROUND: Parturition at term and preterm is characterized by sterile inflammatory processes occurring in the absence of infection whereby peripheral leukocytes infiltrate gestational tissues in response to chemotactic signals. In response to a homing signal, recruited leukocytes undergo diapedesis and extravasate through capillaries, migrating into stromal tissue. There they interact with resident immune and stromal cells to produce a mixture of matrix metalloproteinases, prostaglandins and cytokines including interleukin-1β (IL-1β) and IL-6 that in turn transform the uterus from pregnancy to parturition...

During adolescence, many neural systems, including the dopamine system, undergo essential remodeling and maturation. It is well known that early-life stress (ELS) increases the risk for many psychopathologies during adolescence and adulthood. It is hypothesized that ELS interferes with the maturation of the dopamine system. There is a sex bias in the prevalence of stress-related mental disorders. Information regarding the effects of ELS on brain functioning in females is very limited. In the current study, maternal separation (MS) procedures were carried out to study the effects of ELS on dopamine system functioning in adolescent female rats...

PURPOSE: Body size, from birth throughout adulthood, is associated with breast cancer risk, but few studies have investigated early-life body size and benign breast disease (BBD), a well-established breast cancer risk factor. We consider whether prenatal factors and size at birth, 10, 18 year, and intervening growth, are related to BBD risk. METHODS: The Growing Up Today Study includes 9032 females who completed questionnaires annually from 1996 to 2001, then 2003, 2005, 2007, 2010, and 2013...

: Prenatal psychosocial health has been linked with health behaviors, maternal health, and birth outcomes. This randomized controlled trial evaluated the effects of a prenatal depression intervention on birth outcomes and maternal physical and psychological status at 42 days postpartum. Three hundred fifty-two high-risk pregnant women exposed to obstetric complications with an Edinburgh Postnatal Depression Scale (EPDS) ≥ 9 or a Postpartum Depression Screening Scale (PDSS) ≥ 60 were randomly assigned to the intervention group (n = 176) and control group (n = 176)...

OBJECTIVE: to assess if maternal risk profile and Hospital assistential levels were able to influence the inter-Hospitals comparison in the class 1 and 3 of the "The Ten Group Classification System" (TGCS). METHODS: a population-based analysis using data from Isititutional data-base of an Italian Region was carried out. The 11 maternity wards were divided into two categories: second-level hospitals (SLH), and first-level hospitals (FLH). The recorded deliveries were classified according to the TGCS...

Pharmacological therapy for irritable bowel syndrome (IBS) has not been established. In order to find candidate drugs for IBS with diarrhea (IBS-D), we screened a compound library of drugs clinically used for their ability to prevent stress-induced defecation and visceral hypersensitivity in rats. We selected the bronchodilator aminophylline from this library. Using a specific inhibitor for each subtype of adenosine receptors (ARs) and phosphodiesterases (PDEs), we found that both A2BARs and PDE4 are probably mediated the inhibitory effect of aminophylline on wrap restraint stress (WRS)-induced defecation...

BACKGROUND: Anxiety disorders are common in youth and cause significant distress and impairment to the individual and family. Oxytocin (OT), a nine amino acid peptide, is implicated in anxiety regulation and modulation of close interpersonal and attachment behavior. Anxiety disorders have been linked to low levels of salivary OT in youth. Research has also linked oxytocinergic functioning to social support, warm contact, and bonding, and indicated that contact with attachment figures stimulates OT response...

BACKGROUND: Irritable bowel syndrome (IBS) causes chronic abdominal pain and abnormal bowel movements. The etiology involves complicated interactions among visceral hypersensitivity, disorders related to bowel movements, and stress. Changes in the microbiota affect the IBS pathophysiology. We investigated changes in colorectal motility, structure, and microbiota in response to stress due to maternal separation (MS) and corticotropin-releasing hormone (CRH) administration in rats. SUMMARY: Neonatal rats were separated from their mothers for 3 h daily from postnatal day (PND) 2 to PND14...

Abdominal pregnancy is a potentially life threatening form of ectopic gestation with an incidence of 1% of all the ectopic pregnancies. Rarely, it may reach at advanced gestation and a viable fetal outcome is indeed a rare event. Most of them are terminated earlier due to poor fetal prognosis and higher chances of maternal mortality secondary to haemorrhagic shock following spontanous placental separation. A high index of suspicion is important for making a diagnosis of abdominal pregnancy and its timely management after correct diagnosis...

Thyroid hormones are important for the development of the central nervous system. Since the fetal thyroid gland is not functioning until mid-gestation, transport of maternal thyroid hormones across the placenta is essential during the early phases of gestation. Maternal thyroid deficiency has been associated with a higher incidence of neurodevelopmental disorders in the newborns. The relationship between maternal hypothyroidism and the onset of autism spectrum disorders (ASD) in the offspring, however, is still debated...

Madagascar is among countries where the prevalence of stunting is dramatically high in under 5 years old children. This study investigated the determinants of child stunting based on the UNICEF framework on the causes of malnutrition. A cutoff at 24 months was used to separate the child population into two groups. By using the latest Demographic and Health Survey (2009), logistic regressions were performed to determine the variables associated with stunting. In 2009, 40.1% of the 1,863 children aged 0-23 months and 53...

Previous studies demonstrate that boys' monoamine oxidase A (MAOA) genotype interacts with adverse rearing environments in early childhood, including punitive discipline, to predict later antisocial behavior. Yet the mechanisms by which MAOA and punitive parenting interact during childhood to amplify risk for antisocial behavior are not well understood. In the present study, hostile attributional bias and aggressive response generation during middle childhood, salient aspects of maladaptive social information processing, were tested as possible mediators of this relation in a sample of 187 low-income men followed prospectively from infancy into early adulthood...
