Background. Increased intestinal permeability may be one of the mechanisms of transmission of HIV to the infant through breastfeeding. It correlates with microbial translocation, which can be measured through quantification of bacterial lipopolysaccharide (LPS).Methods. We evaluated levels of plasma LPS (Limulus Amoebocyte Lysate assay), and immune activation markers in serial specimens of ...

In multimale groups where females mate promiscuously, male-infant associations have rarely been studied. However, recent studies have shown that males selectively support their offspring during agonistic conflicts with other juveniles and that father's presence accelerates offspring maturation. Furthermore, it was shown that males invest in unrelated infants to enhance future ...

BACKGROUND: There has been a considerable decline in fetal and neonatal mortality in the Western world. The authors hypothesized that this decline has been largest for boys, since boys have a higher risk of fetal and neonatal death. METHODS: The authors used data from the Medical Birth Registry about all ...

BACKGROUND: Mother-to-child transmission of HIV (MTCT) accounts for more than 90% of pediatric Acquired Immunodeficiency Syndrome (AIDS) cases. Prevention of mother to child transmission (PMTCT) programs are provided for dual benefits i.e. prevention of HIV transmission from mother to child and enrolment of infected pregnant women and their families into ...

BACKGROUND:: Early initiation of antiretroviral therapy (ART) depends on an early infant diagnosis (EID) and is critical to reduce HIV-related infant mortality. We describe the implementation of a routine Prevention of Mother-to-Child Transmission (PMTCT) program and focus on EID to identify opportunities to improve outcomes. METHODS:: HIV-exposed infants and their ...

OBJECTIVE: To evaluate the rate of human papillomavirus (HPV) infection in pregnant women and their neonates, and the risk factors associated with vertical transmission of HPV infection from mothers to neonates. STUDY DESIGN: Cervical HPV testing was undertaken in pregnant women over 36 weeks of gestation, and mouth secretions and ...

BACKGROUND: Both intra-uterine exposure to maternal drugs and HIV are known to adversely affect the developing central nervous system. AIMS: (1) To describe the quality of GMs in infants who were intra-uterinely exposed to maternal opiate abuse and HIV; and (2) to analyze to what extent (a) perinatal events, (b) ...

We examined the effects of infant age and gender on the behaviors of infants and mothers during discipline interactions using longitudinal, naturalistic, home-based, taped observations of 16 mother-infant dyads (eight males and eight females). These observations were conducted between the child ages of 5 and 12 months and used a ...

Infanticide by males is a common phenomenon in mammals, especially primates, as lactation lasts much longer than gestation in many species. Usually, infanticidal episodes occur soon after group takeovers, and are traditionally considered a male reproductive strategy (i.e., support the sexual selection hypothesis, Hrdy, 1974). To verify the validity of ...

Few quantitative descriptions of parturition behavior have been reported in wild nonhuman primates because the majority of births occur at night. We have recorded a daytime birth event of a primiparous black-and-white snub-nosed monkey (Rhinopithecus bieti). The partum stage lasted 4min 30 s, and the female skillfully severed the umbilical ...

Background: Prior to 2010, the World Health Organization recommended that HIV-positive mothers exclusively breastfeed for the first 6 months of life unless replacement feeding was acceptable, feasible, affordable, sustainable, and safe. Community pressure to practice mixed feeding, lack of knowledge on safe feeding, and shame regarding HIV status discourage mothers ...

Herpes simplex virus (HSV) infection of the neonate is uncommon, but genital herpes infections in adults are very common. Thus, although treating an infant with neonatal herpes is a relatively rare occurrence, managing infants potentially exposed to HSV at the time of delivery occurs more frequently. The risk of transmitting ...

ABSTRACT: BACKGROUND: Breastfeeding is a leading cause of infant HIV-1 infection in the developing world, yet only a minority of infants exposed to HIV-1 via breastfeeding become infected. As a genetic bottleneck severely restricts the number of postnatally-transmitted variants, genetic or phenotypic properties of the virus Envelope (Env) could be ...

ABSTRACT: BACKGROUND: The main transmission route of the hepatitis B virus (HBV) is mother to child transmission and contributes significantly to chronic HBV infection. Even though immunoprophylaxis with hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine is administrated to neonates whose mothers are hepatitis B surface antigen (HBsAg) positive, about ...

Increasing breastfeeding initiation and duration in the United States has been identified as a major public health goal. This article presents an initial validation of the Sexual Perceptions of Breastfeeding Scale (SPBFS). The SPBFS was designed to assess the presence of sexual perceptions regarding breastfeeding that may interfere with a ...

The World Health Organisation and the Joint United Nations Programme in 2006 reaffirmed the earlier recommendation of 2000 that all HIV-exposed infants in resource-poor countries should commence cotrimoxazole (CTX) prophylaxis at 6-weeks of life. CTX prophylaxis should be continued until the child is confirmed HIV-uninfected and there is no further ...

Infant cries are a critical survival mechanism that draw the attention of adult caregivers, who can then satisfy the basic needs of otherwise helpless infants. Here, we used functional neuroimaging to determine the effects of infant hunger cries on the brain activity of adults who were in a cognitively nondemanding ...

Infants born to HIV-infected women are at increased risk of impaired neurodevelopment, but little research has attempted to identify modifiable risk factors. The objective of this prospective cohort analysis was to identify maternal, socioeconomic, and child correlates of psychomotor and mental development in the first 18 mo of life among ...

More than 390 000 children are newly infected with HIV each year, only 28 per cent of whom benefit from early infant diagnosis (EID). Rwanda's Ministry of Health identified several major challenges hindering EID scale-up in care of HIV-positive infants. It found poor counseling and follow-up by caregivers of HIV-exposed infants, ...

Diagnosing HIV infection in infants by p24 antigen detection at point of care is likely to reduce infant morbidity and mortality. A fourth generation rapid test evaluated on 202 stored samples from children of known age and clinical presentation demonstrated a sensitivity of <2% for detecting p24 antigen in 61 ...

BACKGROUND: There is increasing evidence of an elevated sex ratio at birth (SRB) in many Asian countries, including Vietnam, and that this prenatal gender inequity is related to sex-selective abortion. However, few studies have investigated the relation between the sex of offspring and delivery care utilization. OBJECTIVE: The aim of ...

Infants and young children are vulnerable in emergencies. The media plays an important role in aid delivery and has a positive impact when reports are accurate. However, the media has been implicated in encouraging harmful aid in the form of donations of infant formula and other milk products. Internet-based media ...

Breastfeeding should be considered a public health issue and the reference normative standards for infant feeding at least to the 6th month of life, with continuation of breastfeeding for 1 year or longer as mutually desired by mother and infant. Numerous studies demonstrate that breastfeeding results in improved infant and ...

Between 1998 and 2007, women in Australia gave birth to ...

  Human parechovirus type 3 (HPeV3) is known to cause sepsis-like syndrome and meningoencephalitis in neonates and young infants. We herein report a neonatal case of sepsis-like syndrome due to HPeV3 infection, diagnosed using polymerase chain reaction (PCR), with a distinctive erythematous rash present mainly on the soles and palms ...

PROBLEM: Malawi's national guidelines recommend that infants exposed to the human immunodeficiency virus (HIV) be tested at 6 weeks of age. Rollout of services for early infant diagnosis has been limited and has resulted in the initiation of antiretroviral therapy (ART) in very few infants. APPROACH: An early infant diagnosis programme ...

Background: Infants are protected from measles infection by maternal measles antibodies (MMA). The level of these MMA at birth in newborn children depends on the levels in their mother and the extent of placental transfer. We investigated maternal HIV infection as a predictor of levels of MMA in mother-infant pairs ...

BACKGROUND:: Early initiation of antiretroviral therapy (ART) has been shown to reduce mortality among perinatally HIV-infected infants, but availability of virologic testing remains limited in many settings. METHODS:: We collected cross-sectional data from mother-infant pairs in three primary care clinics in Lusaka, Zambia to develop predictive models for HIV infection ...

Facial appearance can motivate behaviour and elicit activation of brain circuits putatively involved in reward. Gender differences have been observed for motivation to view beauty in adult faces-heterosexual women are motivated by beauty in general, while heterosexual men are motivated to view opposite-sex beauty alone. Although gender differences have been ...

ABSTRACT: BACKGROUND: The question of when and how to best wean infants born to mothers with HIV requires complex answers. There are clinical guidelines on best approaches but limitations persist when applying them in diverse low-income settings. In such settings, infant-feeding practices are not only dependent on individual women's choices ...

BACKGROUND:: Prematurity increases the peri-natal HIV transmission rate compared to term infants. There is sparse literature documenting the risk of transmission of HIV to extremely low birth weight (ELBW) infants. OBJECTIVE:: To determine the risk of perinatal transmission of HIV to ELBW infants in a tertiary neonatal unit in South ...

Abstract Breast pumps have been used since antiquity, and their form has changed with the available material. The ancient Greeks used the ceramic guttus type, both to empty the breast and feed the infant. The Romans invented glass milk-extractors, sucked by the mother herself to elevate retracted nipples. Devices in ...

Purpose of the study: Previous studies evaluating the frequency of CXCR4-using strains in HIV-1 vertically infected children restricted mainly to patients infected with subtype B or C strains. However, the coreceptor use by non-B or non-C subtypes remains little known, especially in infants. In this study, we determined the HIV-1 ...

Producing estimates of infant (under age 1 y), child (age 1-4 y), and under-five (under age 5 y) mortality rates disaggregated by sex is complicated by problems with data quality and availability. Interpretation of sex differences requires nuanced analysis: girls have a biological advantage against many causes of death that ...

OBJECTIVES: To determine the proportion of infants admitted to our neonatal intensive care unit (NICU) from multiple gestations resulting from artificial reproductive technology (ART), the complications experienced and interventions required by these infants, and the estimated effect of a mandatory policy of single embryo transfer on admissions and complication rates ...

The study of the neurohormonal and behavioral processes and neural mechanisms involved in the development of attachment between the infant and the mother has received increased attention over the last years. Oxytocin has been shown to play a central role in the regulation of affiliate social behavior, including sexual behavior, ...

Infant symbolic play was examined in relation to prenatal alcohol exposure and socioenvironmental background and to predict which infants met criteria for fetal alcohol syndrome (FAS) at 5 years. 107 Cape Coloured, South African infants born to heavy drinking mothers and abstainers/light drinkers were recruited prenatally. Complexity of play, socio-demographic ...

FUT2 is an autosomal gene that controls the secretion of the ABH blood group antigens in organic fluids. The secretor gene plays an important role during intrauterine life. The aim of this study is to investigate a possible association between the ABH system and reproductive success in couples with primary ...

Heavy maternal alcohol consumption during early pregnancy increases the risk of oral clefts, but little is known about how genetic variation in alcohol metabolism affects this association. Variants in the alcohol dehydrogenase 1C (ADH1C) gene may modify the association between alcohol and clefts. In a population-based case-control study carried out ...

Prenatal alcohol exposure can lead to a wide range of deficits known as fetal alcohol spectrum disorder. Epidemiologic studies regarding alcohol consumption in pregnancy have concentrated on North America, but recent reports have suggested that consumption is significant in many parts of the world. In Uruguay, alcohol consumption has changed ...

This study examines the relationships between alcohol taxation, drinking during pregnancy, and infant health. Merged data from the US Natality Detailed Files, as well as the Behavioral Risk Factor Surveillance System (1985-2002), data regarding state taxes on beer, wine, and liquor, a state- and year-fixed-effect reduced-form regression were used. Results ...

Sudden arrhythmic cardiac death can occur in chronic misusers of alcohol. The only findings at post mortem are fatty liver and a negative or low blood alcohol. This is an under-recognized entity. Coroner's post mortems in a typical UK city were studied. Seven out of 1,292 (0.5%) post mortems were ...

BACKGROUND: The safety of small amounts of alcohol drinking and occasional binge-level drinking during pregnancy remains unsettled. We examined the association of maternal average alcohol intake and binge drinking (>or=5 drinks per sitting) with infant mortality, both in the neonatal and postneonatal period. METHODS: Participants were 79,216 mothers who were ...

Prenatal sonography has enabled fetal diagnosis of urologic conditions and is now commonly used in the US. The impact of this technology on the incidence of pediatric urological diagnoses is unknown. We sought to assess trends in prenatal sonography and resulting urologic diagnoses and/or abortions. Using administrative codes in Ingenix, ...

OBJECTIVE: To study the reproductive success of couples with a history of repeated spontaneous abortion (RSA) with respect to the haptoglobin (Hp) phenotypes of both the wife and husband. STUDY DESIGN: This study examined maternal and paternal Hp in 194 couples with primary and secondary RSA recruited from the Center ...

Prenatal exposure to smoking and alcohol increases the risk for Sudden Infant Death Syndrome (SIDS). Physiological changes associated with these exposures are not well studied. Full-term infants were tested within the first 3 days of life. We hypothesized that maternal alcohol consumption and/or smoking during pregnancy would alter autonomic nervous ...

Alcohol policies have potentially far-reaching impacts on risky sexual behavior, prenatal health behaviors, and subsequent outcomes for infants. After finding initial evidence in the National Longitudinal Survey of Youth (NLSY) that changes in the minimum legal drinking age (MLDA) are related to prenatal drinking, we examine whether the drinking age ...

OBJECTIVE: To conduct a systematic review and meta-analyses of studies that test the association between induced or spontaneous abortion and subsequent preterm birth. STUDY DESIGN: International databases were reviewed (1995-2007) using the terms preterm, premature, birth, labor, delivery, abortion, induced abortion, miscarriage and spontaneous abortion. Only studies that met prespecified ...
