Published A new mother's immune status varies with her feeding strategy
(via sciencedaily.com) Original source In one of the first studies of its kind, UC Santa Barbara researchers have found that the immune status of postpartum mothers shifts with how she feeds her baby. Certain inflammatory proteins -- substances that are secreted as part of an immune response -- peak at different times of day, correlating with whether the mothers breastfeed, pump or formula-feed their babies.
Published Personalized screening early in pregnancy may improve preeclampsia detection
(via sciencedaily.com) Original source Study suggests more extensive screening method in the first trimester of pregnancy may improve detection of preeclampsia.
Published Source of pregnancy complications from infections revealed by placenta map
(via sciencedaily.com) Original source The placenta's response to infections from malaria, toxoplasmosis and listeria has been mapped in high resolution, possibly paving the way for new treatment options.
Published Cell contractions drive the initial shaping of human embryos
(via sciencedaily.com) Original source Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell adhesion in this phenomenon and pave the way for improved assisted reproductive technology (ART).
Published Father's gut microbes affect the next generation
(via sciencedaily.com) Original source Researchers changed the composition of the gut microbiota in male mice through common antibiotics, inducing a condition called dysbiosis, and found that: - Mouse pups sired by a dysbiotic father show significantly lower birth weight, and have increased risk of growth disorders and postnatal mortality.
Published Discovery of an atypical heat shock factor, HSF5, involved in meiotic mechanisms: Implications for male infertility
(via sciencedaily.com) Original source Researchers have identified a novel Heat Shock Factor (HSF), designated as HSF5, which plays a crucial role in the completion of meiosis and the activation of genes essential for sperm formation. This discovery provides valuable insights into underlying causes of spermatogenic failure, the major contributor to male infertility. Furthermore, unlike other typical Heat Shock Factors, which primarily regulate gene expression in response to stress, such as heat shock, HSF5 plays a specific role in male germ production during meiosis under non-stress conditions.
Published Pregnancy cytokine levels impact fetal brain development and offspring behavior
(via sciencedaily.com) Original source Researchers have discovered in a preclinical model that cytokines, proteins that control immune response, circulating in maternal blood during pregnancy may mitigate an offspring's risk for psychiatric conditions. The findings are surprising because circulating maternal cytokines are at such low levels that they were not implicated in fetal brain development and offspring behavior before.
Published Dengue fever infections have negative impacts on infant health for three years
(via sciencedaily.com) Original source Dengue infections in pregnant women may have a negative impact on the first years of children's lives, new research has found.
Published Pressure in the womb may influence facial development
(via sciencedaily.com) Original source Physical cues in the womb, and not just genetics, influence the normal development of neural crest cells, the embryonic stem cells that form facial features, finds a new study.
Published Researchers find that accelerated aging biology in the placenta contributes to a rare form of pregnancy-related heart failure
(via sciencedaily.com) Original source In a new study, researchers show that elevated levels of proteins related to cellular senescence, or aging, in the blood and the placenta are linked to this form of heart failure.
Published New study focuses on the placenta for clues to the development of gestational diabetes
(via sciencedaily.com) Original source A new study has identified that a deficit in the placental expression of the gene insulin-like growth factor 1 (IGFBP1) and low IGFBP1 circulating levels are associated with insulin resistance during pregnancy, highlighting a potential risk factor for the development of gestational diabetes.
Published Hypertensive disorders of pregnancy increase risk of cardiovascular death after giving birth
(via sciencedaily.com) Original source Health researchers identify patients at risk for preventable death in the year after pregnancy.
Published Global research team finds no clear link between maternal diabetes during pregnancy and ADHD in children
(via sciencedaily.com) Original source An international research team has just provided valuable evidence through a 20-year longitudinal study to address the longstanding debate concerning the potential impact of maternal diabetes on attention-deficit/hyperactivity disorder (ADHD) in children. This study, analysing real-world data from over 3.6 million mother-baby pairs in China's Hong Kong, Taiwan, New Zealand, Finland, Iceland, Norway and Sweden, showed that maternal diabetes during pregnancy is unlikely to be a direct cause of ADHD.
Published No link between acetaminophen use during pregnancy and children's risk of autism, ADHD, and intellectual disability, says large sibling study
(via sciencedaily.com) Original source In the largest study to date on the subject, researchers found no evidence to support a causal link between acetaminophen use during pregnancy and increased risk of autism, ADHD and intellectual disability in children. The findings use data from a nationwide cohort of over 2.4 million children born in Sweden, including siblings not exposed to the drug before birth.
Published Pregnancy accelerates biological aging in a healthy, young adult population
(via sciencedaily.com) Original source Pregnancy may carry a cost, reports a new study. The research shows that women who reported having been pregnant looked biologically older than women who had never been pregnant, and women who had been pregnant more often looked biologically older than those who reported fewer pregnancies.
Published Even moderate alcohol usage during pregnancy linked to birth abnormalities
(via sciencedaily.com) Original source Researchers have found that even low to moderate alcohol use by pregnant patients may contribute to subtle changes in their babies' prenatal development, including lower birth length and a shorter duration of gestation.
Published Women with obesity do not need to gain weight during pregnancy, new study suggests
(via sciencedaily.com) Original source The guidelines for weight gain during pregnancy in obese women have long been questioned. New research supports the idea of lowering or removing the current recommendation of a weight gain of at least 5 kg.
Published Positive associations between premenstrual disorders and perinatal depression
(via sciencedaily.com) Original source Women affected by premenstrual disorders have a higher risk of perinatal depression compared with those who do not, according to new research. The relationship works both ways: those with perinatal depression are also more likely to develop premenstrual disorders after pregnancy and childbirth. This study suggests that a common mechanism might contribute to the two conditions.
Published Miscarriages linked to health risks in later pregnancies
(via sciencedaily.com) Original source Researchers analyzed 52 studies involving more than 4 million pregnancies across 22 countries to investigate the health impacts of miscarriage, abortion and recurrent pregnancy loss (more than two miscarriages in succession) on subsequent pregnancies. The study found different health risks for each group.
Published Stem cell model offers first glimpse of early human embryonic development
(via sciencedaily.com) Original source The new platform's ethically grounded approach promises to reveal much about how human embryos form during the earliest stages of pregnancy.
