BACKGROUND: Cardiovascular disease in women often develops without conventional risk factors. Prenatal loss is a common pregnancy outcome that may result in physiological changes can increase the potential future risk of cardiovascular disease. Insufficient information exists regarding the impact of pregnancy loss on early markers of cardiovascular disease risk. METHODS AND RESULTS: Cross-sectional analysis of 1767 disease-free women from the MTC (Mexican Teachers' Cohort) who had been pregnant was used to evaluate the relationship between pregnancy loss and carotid intima-media thickness (IMT)...

Progesterone is a steroid hormone secreted from the corpus luteum (CL), which is responsible for establishment and maintenance of pregnancy. Early embryonic mortality often occurs due to inadequate regulation of uterine prostaglandin (PG) F2alpha secretion, leading to decrease in progesterone and loss of pregnancy. The objective of the current study was to determine the effects of fish meal supplementation on luteal sensitivity to intrauterine infusions of PGF2alpha. Non-lactating beef cows received corn gluten meal or fish meal supplementation for 60-days...

Personal care products (PCP) contain a myriad of chemicals generally formulated to provide a safe and beneficial use. Nonetheless, an increasing amount of laboratory animal and human studies indicate that some chemicals in PCP are associated with decreased hormone production, diminished ovarian reserve, ovarian cancer, and early pregnancy loss. The ovary is key to female fertility by providing the eggs and sex steroid hormones for fertilization and maintenance of reproductive function, respectively. Thus, understanding how chemicals in PCP affect the ovary will shed some light on their potential effects on female fertility...

A proper canine neonatal assistance, required to reduce the high perinatal loss rate, imply a full knowledge about the fetal-to-neonatal physiology. Because fetal fluids play an important role throughout mammals pregnancy, influencing fetal growth and development, fetal well being, and contributing to guarantee the most suitable environment for the fetus, the knowledge about fetal fluids biochemical composition is of major importance. At first, the biochemical composition of fetal fluids collected by normal developed, healthy and viable newborns, is necessary to depict the normal features, and represent the first step for the further detection of abnormalities associated to fetal/neonatal distress and useful for the early identification of newborns needing special attention, immediately after birth...

The concentration of circulating pregnancy associated glycoproteins (PAGs) early in pregnancy may serve as markers to predict late embryonic mortality or fetal mortality in cattle. In this study, pregnancies were established in dairy cows, by either fixed-time AI (FTAI) or fixed-time embryo transfer (FTET) with in vitro produced embryos. Circulating PAGs were measured with different combinations of antibodies in either a laboratory-based ELISA or a commercial ELISA. For the in-house ELISA, three monoclonal 'trapping' antibodies (A6, J2, and L4) and two polyclonal 'detection' antisera (antibodies F2 or 45) were used to quantify PAGs in serum from the same cows...

Decanoic acid (DA) is a medium-chain fatty acid used in the manufacture of various products including plastics, cosmetics, and lubricants. In addition to antiviral and antibacterial effects, DA's, reported biological activities include regulation of signaling pathways and redox homeostasis in various human cell types. The influence of DA on functional properties of human trophoblasts, including proliferation, invasion and apoptosis is currently unknown. In the present study, we evaluated the anti-proliferative and anti-invasive effects of DA on the human trophoblast cell line HTR8/SVneo...

Approximately 80% of cheetahs living in typical zoological collections never reproduce. In more than 60% of breedings, the female is confirmed to ovulate, but parturition fails to occur. It is unknown if these non-pregnant intervals of elevated progesterone (deemed luteal phases) are conception failures or a pregnancy terminating in embryonic/fetal loss. There have been recent advances in metabolic profiling and proteome analyses in many species with mass spectrometry used to identify 'biomarkers' and mechanisms indicative of specific physiological states (including pregnancy)...

Phosphatidylethanolamine (PE) is a major phospholipid species with important roles in membrane trafficking and reorganization. Accumulating clinical data indicate that the presence of circulating antibodies against PE is positively correlated with the symptoms of antiphospholipid syndromes (APS), including thrombosis and repeated pregnancy loss. However, PE is generally sequestered inside a normal resting cell, and the mechanism by which circulating anti-PE antibodies access cellular PE remains unknown. The studies presented here were conducted with synthetic PE-binding agents, plasma samples from patients with anti-PE autoimmunity, and purified anti-PE antibodies...

Infertility and subfertility negatively impact the economics and reproductive performance of cattle. Of note, significant pregnancy loss occurs in cattle during the first month of pregnancy, yet little is known about the genetic loci influencing pregnancy success and loss in cattle. To identify quantitative trait loci (QTL) with large effects associated with early pregnancy loss, Angus crossbred heifers were classified based on day 28 pregnancy outcomes to serial embryo transfer. A genome wide association analysis (GWAA) was conducted comparing 30 high fertility heifers with 100% success in establishing pregnancy to 55 subfertile heifers with 25% or less success...

Maternal obesity can cause complications for both women and their offspring for generations. Therefore, we intended to verify the repercussions of induction of transgenerational obesity on biochemical parameters, reproductive performance, and congenital anomaly frequency in Wistar rats. Female rats were used from successive generations. The female rats of parental generation (F0, n=10) were mated to obtain their offspring (F1 generation). F1 female rats received a monosodium glutamate (MSG) solution to induce obesity (n=07) or vehicle (control, n=06) during the neonatal period...

Ensuring quality of life for increasing numbers of women surviving cancer has become a key challenge. Patients need to be counseled on potential fertility loss resulting from gonadotoxic treatments, and referred to fertility specialists to discuss existing options and available results. Areas covered: Fertility preservation options have existed for over twenty years. The proposed fertility preservation approach depends on patient age, the urgency of required chemotherapy, and psychosocial factors such as financial concerns, especially in countries where techniques are not covered by social security...

Background: There has been a great deal of concern about the mental health of women whose pregnancies involve miscarriage, termination of a pregnancy (ToP), child death or where a child has been given up for adoption. Despite this concern there has been remarkably little population-based research which has addressed the long-term consequences of pregnancy loss and child death. This study investigated the maternal mental health consequences of women whose pregnancies involve miscarriage, ToP, child death or where a child has been given up for adoption at two different time points, adjusting for socio-demographic characteristics and baseline mental health...

Miscarriage is the unwanted ending of a pregnancy before 20 weeks gestation. Women experiencing miscarriage require specialized care from nurses and other healthcare professionals. Many women are dissatisfied with emergency care related to miscarriage and desire honest communication, validation of urgency, and more robust information at discharge. Perinatal bereavement education offers an opportunity for emergency department nurses to acquire specific knowledge and communication skills that assist with understanding the individualized experience of early pregnancy loss...

Natural and synthetic progestogens have been commonly used to prevent recurrent pregnancy loss in women with inadequate progesterone secretion or reduced progesterone sensitivity. However, the clinical efficacy of progesterone and its analogs for maintaining pregnancy is variable. Additionally, the underlying cause of impaired endometrial progesterone responsiveness during early pregnancy remains unknown. Here, we demonstrated that uterine-selective depletion of BMI1, a key component of the polycomb repressive complex-1 (PRC1), hampers uterine progesterone responsiveness and derails normal uterine receptivity, resulting in implantation failure in mice...
