Vaccination during pregnancy is increasingly being recognised internationally a useful means of preventing illness in pregnant women and their newborns. It has been used since the 1960s, when it was found that tetanus vaccine was highly effective in preventing neonatal tetanus, but interest has greatly increased over the last few years. As new data become available showing the numerous benefits of maternal immunisation and its potential for improving maternal and neonatal health in relation to a number of infectious conditions, it is being increasingly incorporated into the national vaccination programmes around the world...

The obstetrics-gynecology community has issued a call to action to prevent toxic environmental chemical exposures and their threats to healthy human reproduction. Recent committee opinions recognize that vulnerable and underserved women may be impacted disproportionately by environmental chemical exposures and recommend that reproductive health professionals champion policies that secure environmental justice. Beauty product use is an understudied source of environmental chemical exposures. Beauty products can include reproductive and developmental toxicants such as phthalates and heavy metals; however, disclosure requirements are limited and inconsistent...

The Mediterranean diet has been for a very long time the basis of food habits all over the countries of the Mediterranean basin, originally founded on rural models and low consumption of meat products and high-fat/high-processed foods. However, in the modern era, the traditional Mediterranean diet pattern is now progressively eroding due to the widespread dissemination of the Western-type economy, life-style, technology-driven culture, as well as the globalisation of food production, availability and consumption, with consequent homogenisation of food culture and behaviours...

HLA-G is a non-classical class I HLA antigen, normally expressed in high levels only on extravillous cytotrophoblast. It has immunosuppressive properties in pregnancy and has also been found to be upregulated on leucocytes in viral infection. In this study, proportions of all leucocyte subsets expressing HLA-G were found to be low in healthy subjects positive or negative for cytomegalovirus (CMV). Significantly greater proportions of CD4+CD69+ and CD56+ T cells expressed HLA-G compared to other T cells. However, following stimulation with CMV antigens or intact CMV, proportions of CD4+, CD8+, CD69+ and CD56+ T cells, and also B cells expressing HLA-G were significantly increased in CMV+ subjects...

Women's workplaces should guarantee healthy pregnancies while supporting pregnant women as workers. In Québec (Canada), a pregnant worker exposed to a "danger" for herself or her fetus may ask her employer to be reassigned to other work appropriate to her skills. This approach differs from other regulatory contexts in North America in that protection of fetal and maternal health is embedded in the health and safety legislation. The advantage is that the pregnant worker is guaranteed access to her full salary, but some may question whether specific provisions for pregnant women single out such women and produce risks for their careers or, conversely, pregnancy should receive even more special consideration...

Chemokines play an important role in regulating the complex immune system at the maternal-fetal interface during pregnancy. Among various chemokines, C-C motif chemokine ligand 2 (CCL2) plays a role in the recruitment of immune regulatory cells to implantation sites within the endometrium. In cattle, CCL2 is abundantly expressed in the uterine endometrium. However, its intracellular signaling has not been identified. In this study, we examined the effects of CCL2 on bovine endometrial (BEND) cell proliferation...

Diagnostic information from prenatal screening for Down syndrome can help families prepare for the birth of a child with special needs or help them decide whether they want to continue with the pregnancy. Currently in the UK women are offered the combined screening test (a blood test and an ultrasound) that categorizes them into "higher risk" or "lower risk" groups (see www.nhs.uk). Women at higher risk are offered a diagnostic test, such as amniocentesis or chorionic villus sampling (CVS). These diagnostic tests are invasive and carry a 0...

By virtue of their religious principles, Jehovah's Witnesses (JWs) generally object to receiving blood products, raising numerous ethical, legal, and medical challenges for providers who care for these patients, especially in the emergent setting. In this review, we discuss several areas relevant to the care of JWs, including the current literature on "bloodless" medical care in the setting of peri- and intra-operative management, acute blood loss, trauma, pregnancy, and malignancy. We have found that medical and administrative efforts in the form of bloodless medicine and surgery programs can be instrumental in helping to reduce risks of morbidity and mortality in these patients...

BACKGROUND: Striae gravidarum (SG), or stretch marks of pregnancy, begin as erythematous streaks, and mature into hypopigmented atrophic bands. OBJECTIVES: To investigate molecular alterations that may promote atrophy of SG, we investigated dermal type I collagen fibrils, which provide human skin with support. METHODS: We obtained skin samples of recently developed, erythematous abdominal SG from pregnant women. To examine the organization of collagen fibrils, second-harmonic generation imaging was performed using multiphoton microscopy...

REVIEW
Marian J Bakermans-Kranenburg, Marinus H van IJzendoorn
The current review focuses on a dimension of parenting that has largely been neglected in studies on human parenting, namely parental protection. Human protective parenting can be observed already during pregnancy, when mothers experiencing morning sickness avoid foods that are likely to carry pathogens and thus could be harmful to the fetus. After the birth of the baby, one of the foremost anxieties of parents is that their child will be abused or killed by strangers. Protective parenting seems to be a species-wide evolutionary-based behavior complementary to the innate bias of each newborn to strive for proximity to a potentially protective attachment figure...

STUDY QUESTION: Is resveratrol able to prevent the lipopolysaccharide (LPS)-induced preterm labor in 15-day pregnant BALB/c mice? SUMMARY ANSWER: Resveratrol prevented the LPS-induced onset of preterm labor in 64% of the cases and showed anti-inflammatory and tocolytic effects by downregulating COX-2 and iNOS expression and NOS activity, and by changing the uterine prostaglandin and endocannabinoid profiling. WHAT IS KNOWN ALREADY: Genital tract infections by Gram-negative bacteria are a common complication in human pregnancy and have been shown to increase risk of preterm delivery...

INTRODUCTION: Abnormally invasive placenta (AIP) involves abnormal adherence of the placenta to the myometrium, and is associated with severe pregnancy complications such as blood transfusion and hysterectomy. Knowledge of outcomes has been limited by small sample sizes and a focus on maternal rather than neonatal outcomes. This study uses population-level data collected over ten years to investigate maternal and neonatal outcomes and trends in incidence of AIP (also known as placenta accreta, increta and percreta)...

Anuradha, Amitabh Krishna
Cynopterus sphinx, a fruit bat, undergoes delayed embryonic development during the winter months, a period that corresponds to low levels of progesterone and estradiol synthesis by the ovary. Kisspeptins (KPs) are a group of neuropeptide hormones that act via G-protein coupled receptor 54 (GPR54) to stimulate hypothalamic secretion of Gonadotropin-releasing hormone, thereby regulating ovarian steroidogenesis, folliculogenesis, and ovulation. GPR54 is also expressed in the ovary, suggesting a direct role for KPs in ovarian steroidogenesis...

Zika virus (ZIKV) has been of major international public health concern following large outbreaks in the Americas occurring in 2015-2016. Most notably, ZIKV has been seen to pose dangers in pregnancy due to its association with congenital abnormalities such as microcephaly. Numerous experimental approaches have been taken to address how the virus can cross the placenta, alter normal fetal development, and disrupt specific cellular functions. Many areas concerning the mechanisms of transmission, especially from mother to fetus, are largely unknown but demand further research...
