A few studies have revealed that the advanced glycation content of the vaginal wall in pelvic organ prolapse tissues is elevated. This elevation makes advanced glycation a significant association with the disease. Early detection of vaginal wall glycation could therefore be relevant in the prevention and management of pelvic organ prolapse. A vaginal wall biopsy to detect this would be ideal, but is invasive. Therefore the use of a more accessible organ to access, such as skin, would be beneficial. Our previous independent study suggests that conditions such as pregnancy, can induce a change in the vaginal tissues' glycation content...

Aging is a progressive internal physiological deterioration of the organism, leading to the occurrence of age-related lethal diseases. It has become a major societal challenge to understand the processes that drive aging and to develop rational pharmacological agents and dietary approaches to fight against age-related deterioration and diseases. Interestingly, several lines of evidence highlight an influence of the developmental period on the risk of age-related diseases later in life. This field is known as the developmental origins of health and disease...

Amniotic fluid embolism (AFE) is an unpredictable, dreadful complication of pregnancy or childbirth. EA typically includes in the same lapse of time respiratory, haemodynamic, neurological and hemorrhagic symptoms (from early and severe coagulopathy). Immediate supportive treatment by a multidisciplinary team is the cornerstone of the management. Between 2010 an 2012 in France, 24 deaths were related to AFE giving a maternal mortality ratio of 1/100,000 live births (CI 95% 0.6-1.4). AFE ranks as the second leading cause of direct maternal death...

OBJECTIVE: Women are at increased risk of developing cardiovascular disease (CVD) after preeclampsia. Proneurotensin 1-117 (pro-NT) and prorelaxin 2 connecting peptide (pro-RLX2) have recently emerged as potential biomarkers for CVD risk in women. We assessed pro-NT and pro-RLX2 levels in women with and without a history of preeclampsia. STUDY DESIGN: 339 women with a history of early-onset preeclampsia and 327 women with an uncomplicated pregnancy underwent cardiovascular screening 10 years after delivery (the Preeclampsia Risk EValuation in FEMales (PREVFEM) cohort)...

The obesity epidemic in the United States and other countries has contributed to an increase in the rates of gestational diabetes and hypertension. In the past, it was thought that most cases of gestational diabetes and hypertension would resolve after completion of pregnancy. In this issue of the Journal, Pace et al. (Am J Epidemiol. 2017;186(10):1115-1124) clearly documented that both gestational diabetes and hypertension lead to diabetes and hypertension and that the combination of both during pregnancy leads to very high rates of subsequent diabetes and hypertension...

BACKGROUND: Although previous studies suggest that the intentions of mothers to breastfeed during pregnancy strongly predict actual breastfeeding practice, no studies have examined the changes in the intentions of mothers to breastfeed from the prenatal to neonatal periods. The purpose of this study was to examine changes in intended breastfeeding duration from the prenatal to neonatal periods, their association with actual duration, and predictors for shortened duration. METHODS: The Infant Feeding Practices Study II was a longitudinal study of mothers in the United States...

BACKGROUND & AIMS: Programming of infant development and later health may depend on early-milk polyunsaturated fatty acids (PUFA) contents, that are very variable between women for reasons not well elucidated. Indeed, a high n-6/n-3 PUFA in milk was associated with higher adiposity, arterial pressure and lower psychomotor scores in childhood. We aimed to explore the respective contribution of several maternal and perinatal factors to the variability of linoleic (LA), α-linolenic (ALA), arachidonic (AA), and docosahexaenoic (DHA) acid levels in early milk...

BACKGROUND: The association between maternal infection and neurodevelopmental defects in progeny is well established, although the biological mechanisms and the pathogenic trajectories involved have not been defined. METHODS: Pregnant dams were injected intraperitoneally at gestational day 9 with polyinosinic:polycytidylic acid. Neuronal development was assessed by means of electrophysiological, optical, and biochemical analyses. RESULTS: Prenatal exposure to polyinosinic:polycytidylic acid causes an imbalanced expression of the Na(+)-K(+)-2Cl(-) cotransporter 1 and the K(+)-Cl(-) cotransporter 2 (KCC2)...

BACKGROUND: In the last 20 years, adolescent pregnancy has become one of the most critical problems affecting women in Latin America and the Caribbean. METHODS: This qualitative study was based on in-depth interviews with 29 teen mothers. All of the pregnant teens were from low- to lower-middle-class social strata in the Mexico City metropolitan area. The family (living with the girl) and the individual context of pregnant teens were analysed on the basis of data from at least three interviews: during pregnancy and at approximately 6 and 24 months following delivery...

RATIONALE: Pregnancy and lactation-associated osteoporosis (PLO) is very rare, but it can cause severe vertebral compression fractures with disabling back pain. Although it is a rare, PLO must be kept in mind in the differential diagnosis in patients presenting with low back pain during or after pregnancy. PATIENT CONCERNS: A 23-year-old woman who suffered from lumbago and fractures in the vertebral column 1 month after delivery. DIAGNOSIS: Pregnancy and lactation-associated osteoporosis...

Maternal lead exposure is associated with poor birth outcomes. However, modifying effects of polymorphism in glutathione S-transferases (GST) gene and infant sex remain unexplored. Our aim was to evaluate whether associations between prenatal lead and birth outcomes differed by maternal GST genes and infant sex. Prospective data of 782 mother-child pairs from Mothers and Children's Environmental Health (MOCEH) study were used. The genotyping of GST-mu 1 (GSTM1) and theta-1 (GSTT1) polymorphisms was carried out using polymerase chain reaction...

Benzo(a)pyren-7,8-dihydrodiol-9,10-epoxide (BPDE) is an endocrine disrupter and ultimate carcinogenic product of benzo(a)pyrene (BaP). Numerous studies have shown that BPDE causes trophoblast-related diseases, such as preeclampsia, growth restriction or miscarriages. However, the underlying mechanism, especially the mitochondria-related BPDE-induced trophoblast dysfunction remains unknown. In this study, we examined mitochondrial functions in BPDE-induced human trophoblast cell line Swan 71. BPDE decreased cell ability, attenuated cell invasion and HCG secretion, induced cell apoptosis, decreased mitochondrial membrane potential, increased reactive oxygen species (ROS) and MDA, and decreased SOD activity in a dose-dependent manner...

BACKGROUND: Globally, prematurity is the leading cause of death in children under the age of 5. Many efforts have focused on clinical approaches to improve the survival of premature babies. There is a need, however, to explore psychosocial, sociocultural, economic, and other factors as potential mechanisms to reduce the burden of prematurity. Women's empowerment may be a catalyst for moving the needle in this direction. The goal of this paper is to examine links between women's empowerment and prematurity in developing settings...

Pregnancy in the context of pulmonary hypertension is characterised by high mortality for the mother and the foetus and is therefore strongly discouraged ; contraception has to be prescribed to patients in reproductive age. Women who decide to continue their pregnancy should be followed by multidisciplinary teams in specialised centres. A specific treatment should be defined with no delay. In case of clinical deterioration, the early, intravenous administration of prostacyclin should be considered. The ideal time and method of delivery are still disputed...

REVIEW

Low cobalamin intake and status during pregnancy or lactation have been linked to adverse maternal and perinatal health outcomes, whereas low cobalamin status during early childhood is associated with impaired development in children. Women who begin pregnancy with depleted stores (low or very low plasma cobalamin) will give birth to depleted infants who are likely to develop deficiency symptoms during the first few weeks or months postpartum. Newly ingested cobalamin during pregnancy and lactation (from diet or supplements) is transferred to the child and is not likely to correct cobalamin status in depleted women...

BACKGROUND: Antenatal care uptake is among the key indicators for monitoring the progress of maternal outcomes. Early initiation of antenatal care facilitates the timely management and treatment of pregnancy complications to reduce maternal deaths. In Ethiopia, antenatal care utilization is generally low, and delayed initiation of care is very common. We aimed to systematically identify and synthesize available evidence on delayed initiation of antenatal care and the associated factors in Ethiopia...
