A new study suggests that women who have had a caesarean section may be at higher risk of stillbirth in subsequent pregnancies. The research found that the risk of stillbirth was greater for women who had previously given birth by caesarean section, with an increased risk starting at around 34 weeks of their second pregnancy.
Women with myasthenia gravis are at increased risk of complications during pregnancy and childbirth, including higher rates of cesarean section and preterm rupture of amniotic membranes. However, neonatal deaths and prematurity were not significantly affected by the condition.
Pregnant women exhibit enhanced odor sensitivity and unpleasantness, which may help protect against stress. A study also found that brain areas mediating 'reward' are stimulated by pup suckling in rat mothers, suggesting a potential link between smell, reward, and maternal bonding.
A study published in AIDS found that placental malaria significantly increases the risk of mother-to-child HIV transmission. The study, which followed 746 HIV-positive mothers and their infants in Rakai, Uganda, suggests that preventing and treating malaria during pregnancy could reduce transmission rates.
A study by the Lister Fertility Clinic in London found that women who participated in an egg-sharing program did not have a lower chance of getting pregnant or having a live birth compared to those who didn't participate. The researchers also found no evidence of increased risk of ovarian hyperstimulation syndrome among donors.
A study highlights the rise of vitamin D deficiency and rickets in children and pregnant women, particularly in immigrant groups in more temperate regions. Experts recommend extra dietary vitamin D supplementation for these populations to prevent deficiencies.

The study highlights the need for closer monitoring and counseling of high-risk patients.
Researchers at UT Southwestern discovered that administering the drug trichostatin A can effectively delay the start of labor in mice by allowing progesterone to continue functioning. This is significant because mice have a short gestation period, and pre-term birth affects over 460,000 infants annually.
A mandated food additive to combat high fetal development risks may inadvertently harm seniors due to low levels of vitamin B-12. The condition, which affects nearly half of US deaths annually, has been linked to cardiovascular diseases and mental confusion in some cases.
The new test uses PAP smears to isolate and genetically identify foetal cells, allowing for non-invasive prenatal diagnosis of chromosomal and single gene disorders. This reduces the risk of miscarriage associated with invasive tests and increases accessibility to prenatal testing for all pregnant women.
A study of 34 surrogate mothers found that none reported misgivings about handing over the baby, with most enjoying good relations with commissioning couples. However, some experienced mild psychological difficulties after handover, which subsided with time.
A study by Dr Ole Christiansen found that women who gave birth to a boy first were at higher risk for subsequent miscarriages and may not be able to carry a child to full term without treatment. The researcher believes that the immune system's reaction to male foetuses is the explanation for these findings.
A study by Elizabeth Asung found that the risk of ectopic pregnancies after IVF-ET decreases with age in women with tubal disease. This is a surprising finding, as the risk typically increases with age in the general population. The study analyzed data from 97,240 women aged 18-50 who underwent IVF between 1991 and 1999.
A study by Kaiser Permanente found that targeted interventions to increase multivitamin use among women of childbearing age had no significant long-term impact. Despite efforts to educate healthcare providers and pharmacists, the success of these interventions was hampered by inadequate implementation and lack of behavioral change.
The study found that single embryo transfer (SET) does not reduce the chances of having a baby, with similar cumulative live birth rates to dual transfers when previously frozen embryos are included. SET also carried fewer risks to mothers and fetuses, with only three sets of twins out of 107 women.
Researchers found a clear association between increased DDT concentrations in maternal blood and decreased chance of pregnancy in daughters. The opposite effect of DDE concentrations was unexpected, but may explain the lack of large changes in human reproductive performance after DDT introduction.
A ferret protein called glucose-6-phosphate isomerase (GPI) plays a key role in the reproductive process, allowing fertilized embryos to implant successfully. The discovery also sheds light on the mechanism of cancer cells, which can co-opt this process to invade healthy tissues.
New guidelines improve pregnancy, labour, and delivery care for HIV-positive women. These updated recommendations allow for longer, healthier pregnancies and increased chances of healthy, HIV-free offspring.
Pregnant women should undergo thorough breast examinations to detect breast cancer, as diagnosis is often delayed due to hormonal changes. Ultrasonography is the best method for detecting cancerous lumps during pregnancy.

A study of over 570 children found that those who were breastfed had better math, spelling, and reading skills compared to bottle-fed children whose mothers smoked during pregnancy. The researchers suggest that long-chain polyunsaturated fatty acids in breast milk may promote brain development and counteract the negative effects of smo...
Researchers found nearly a third of HIV positive male couples became parents through assisted reproduction, while only one out of ten HIV positive female couples were successful. The study's findings suggest HIV positive men may be more suitable candidates for fertility treatments due to lower infection rates.
A Cumbria study finds a 17% higher risk of neural tube defects and 12% higher heart defect risk near incinerators, but no increased risk for babies born before their operational period. The authors suggest further investigation due to limited emissions data.
A recent study found that 20% of pregnant women show signs of depression, yet only 13.8% receive mental health counseling or treatment during pregnancy. The study highlights the need for increased awareness and screening to address post-partum depression risks associated with hormone imbalances and fetal exposure.
A recent study published by the University of Rochester Medical Center found that consuming large quantities of seafood during pregnancy does not pose a detectable risk to children. The study, which followed 300 children from birth in 1989 and 1990, found no adverse effects from low levels of mercury in fish.
Researchers found evidence of sympatric speciation in seahorses due to their size-specific mating practice and disruptive selection. This study suggests that male pregnancy and monogamy may play a key role in creating new species without geographic barriers.
A retrospective cohort study found that pregnant teens, particularly those from under-resourced backgrounds, require adequate calcium intake to support fetal bone growth. The study's findings suggest a correlation between high maternal dairy consumption and improved fetal bone length and overall nutrition.
A study by Makrina Savvidou and colleagues found that impaired placental blood flow precedes pre-eclampsia in pregnant women. Raised concentrations of asymmetric dimethylarginine (ADMA) are strongly associated with reduced arterial dilation and increased risk of pre-eclampsia.
A recent study by French researchers found that nearly two-thirds of unplanned pregnancies occurred among women using effective contraception methods like the Pill and IUD. The study suggests that there is often a mismatch between a woman's contraceptive needs and the methods she uses.
Researchers discovered that lambs born from undernourished mothers exhibit significantly shorter gestation periods compared to those from well-fed mothers. The study suggests that maternal undernutrition around the time of conception may trigger an early birth, potentially due to hormonal changes in fetal development.
Research suggests that undernutrition in pregnant women can lead to premature birth, with fetuses having accelerated adrenal gland maturation and premature delivery. Despite this, lambs born prematurely were not underweight or small for their gestational age.
A collaborative research group investigated whether Down's syndrome and NTD arise more often in the same family. The study found a significant link between the two conditions, with increased rates of pregnancy loss among families at high risk of NTD and Down's syndrome.
A new study published in Archives of General Psychiatry reveals that high prenatal alcohol use significantly increases the risk of a child developing drinking-related problems by age 21. The research found that 14% of young adults with prenatal exposure to five or more drinks per occasion had alcohol problems, compared to just 4.5% wit...
A study found that prenatal alcohol exposure of less than one drink per day can impair executive functioning (EF) in early childhood, including working memory, planning, and inhibitory control. Children exposed prenatally to alcohol had difficulty following rules and performing tasks that required inhibition.
Researchers found that positive attitudes toward exercise most strongly influenced intention, followed by control over obstructing factors. Pregnant women who exercised reported improved physical condition, reduced discomfort, and increased energy. Postpartum barriers include exhaustion and lack of time.
The first International Preeclampsia Summit is being held to bring together experts in the field to discuss ways to intervene and reduce maternal illness and death due to preeclampsia. The summit aims to prioritize appropriate treatment options for this top cause of maternal mortality.
A study by Johns Hopkins Bloomberg School of Public Health found that folic acid-iron supplementation reduced the incidence of low birth weight by 16% and multiple micronutrient supplements by 14%. This research aims to improve maternal health and child survival in developing countries
Researchers from Italy studied over 14,000 births and found a significant disparity in sex ratios between optimal and sub-optimal reproductive conditions. The study suggests that nature tries to compensate for the vulnerability of male babies by favoring them in favorable months.
A study found that women with bacterial vaginosis or abnormal vaginal flora had a higher risk of late miscarriage and spontaneous preterm delivery. Treating these conditions with antibiotics may reduce this risk, with the number of women needed to be treated calculated at around ten.
A quadruple test that measures four maternal blood markers is more effective than earlier single marker tests in detecting Down's syndrome pregnancies. The test detected 81% of Down's syndrome cases, while a single marker test detected only 51%.
A two-year planning process in high-poverty neighborhoods with diverse communities was successful, while others lacked interest and leadership. Effective communication methods, community involvement, and strong ties to local churches were key factors in the most successful neighborhoods.
Scientists found that elevated levels of sFlt1 protein mediate the progression to preeclampsia by reducing angiogenic factors. Reducing VEGF-A in kidney cells also caused similar kidney disease, suggesting a plausible scenario for preeclampsia
A study conducted in the Artibonite region of Haiti shows that decentralizing prenatal syphilis screening from a regional hospital to community dispensaries has led to a significant reduction in congenital syphilis rates. By implementing on-site blood testing and treatment, the program has cut syphilis cases by 75%.
Researchers found that plasma glucose levels were poorly correlated with birth weight, and factors like smoking, pregnancy weight, and weight gain during pregnancy were more important predictors. The authors also questioned the historic link between gestational diabetes and large-for-gestational-age (LGA) neonates.
