Published Discrimination during pregnancy can affect infant's brain circuitry (via sciencedaily.com) Original source
Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study finds. These effects, the researchers say, are separate from those caused by general stress and depression. The study was published in the journal Neuropsychopharmacology.
Published Spike in premature births caused by COVID, halted by vaccines, study finds (via sciencedaily.com) Original source
COVID-19 caused an alarming surge in premature births, but vaccines were key to returning the early birth rate to pre-pandemic levels, according to a new analysis of California birth records.
Published Researchers develop new method for prenatal genetic testing (via sciencedaily.com) Original source
Researchers have developed a non-invasive genetic test that can screen the blood of pregnant individuals to survey all genes from the fetal genome.
Published High levels of maternal stress during pregnancy linked to children's behavior problems (via sciencedaily.com) Original source
Children whose mothers are highly stressed, anxious or depressed during pregnancy may be at higher risk for mental health and behavior issues during their childhood and teen years, according to new research.
Published Exposure to air pollution in utero may affect reproductive system development (via sciencedaily.com) Original source
From invisible wafts of diesel exhaust to sun-choking plumes of orange smoke, air pollution is known to damage respiratory well-being. Now, research suggests another reason to hold our breath: Polluted air also may hurt reproductive health. In a study of air pollution data in relation to markers of reproductive development in infancy, Rutgers researchers found certain pollutants may negatively alter anogenital distance, a measure of prenatal exposure to hormones.
Published New study finds association between insecticide exposure and lower sperm concentration in adult men (via sciencedaily.com) Original source
Researchers have found in a new systematic review that there is a strong association between insecticide exposure and lower sperm concentration in adult men globally.
Published Clinical trial data suggests prenatal vitamin D reduces a child's risk of asthma (via sciencedaily.com) Original source
A review of 15 years' worth of data found that vitamin D supplementation during pregnancy was linked to reduced rates of asthma and wheezing in children compared to standard prenatal multivitamin.
Published Blood clotting risk quickly drops after stopping hormonal contraceptives (via sciencedaily.com) Original source
Using birth control pills and other hormone-based contraceptives is known to elevate the risk of blood clots, but a new study suggests that this risk largely goes away within two to four weeks after one stops using these contraceptives. The findings can help patients and doctors weigh the benefits and risks of hormonal contraceptives and guide when to stop using them ahead of events that could further increase the risk of dangerous clots, such as major surgery, prolonged periods of immobility, or when tapering anticoagulant medications after a blood clot.
Published Infection with common cat-borne parasite associated with frailty in older adults (via sciencedaily.com) Original source
A new study of 601 older adults found that those with higher serointensity -- or a higher concentration of antibiodies -- to the cat-borne parasite Toxoplasma gondii are more likely to show signs of frailty, including exhaustion, loss of muscle mass and other indications of declining health. T. Gondii has previously been associated with risk-taking behavior and mental illness.
Published Paid family leave boosted postpartum wellbeing, breastfeeding rates (via sciencedaily.com) Original source
A new study has found postpartum individuals living in states with generous mandated paid family and medical leave (PFML) are more likely to breastfeed and less likely to experience postpartum depression symptoms compared to those living in states with little or no mandated state-paid leave. The findings were even more pronounced among lower-income populations covered by Medicaid.
Published Mobile phone use may affect semen quality, study shows (via sciencedaily.com) Original source
Does electromagnetic radiation emitted by mobile phones affect semen quality? While various environmental and lifestyle factors have been proposed to explain the decline in semen quality observed over the last fifty years, the role of mobile phones has yet to be demonstrated. A team has now published a major cross-sectional study on the subject. It shows that frequent use of mobile phones is associated with a lower sperm concentration and total sperm count.
Published Maternal microbiota can affect fetal development (via sciencedaily.com) Original source
Significant differences in the gene activity of the fetal intestine, brain and placenta were identified, depending on the microbes in the mother's body and the compounds produced by them. The findings indicate that maternal microbes are important to her offspring's development and health.
Published Contraceptive pill users less likely to report depression (via sciencedaily.com) Original source
A new study has shown that women who are taking the oral contraceptive pill are less likely to report depression. The research, which analysed data from 6,239 women in the United States aged 18-55 years old, found that the prevalence of major depression amongst users of the oral contraceptive pill (OCP) was significantly lower, at 4.6%, compared to former OCP users (11.4%).
Published Sperm adjust their swimming style to adapt to fluctuating fluid conditions (via sciencedaily.com) Original source
Sperm can modulate their energetics by regulating their flagellar waveform -- how the sperm oscillate their tails -- in order to adapt to varying fluid environments, potentially optimizing their motility and navigation within the reproductive tract, according to new research.
Published COVID vaccination in female, male partners does not increase risk of miscarriage, study finds (via sciencedaily.com) Original source
A new study provides deeper insight into the safety of COVID-19 vaccines for people planning to become pregnant. The study found no increased risk of early or late miscarriage as a result of male or female partners getting a COVID-19 vaccine prior to conceiving.
Published Possible cause of male infertility (via sciencedaily.com) Original source
Mature spermatozoa are characterized by an head, midpiece and a long tail for locomotion. Now, researchers have found that a loss of the structural protein ACTL7B blocks spermatogenesis in male mice. The cells can no longer develop their characteristic shape and remain in a rather round form. The animals are infertile.
Published Membrane transporter ensures mobility of sperm cells (via sciencedaily.com) Original source
Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.
Published Zika infection in pregnant macaques slows fetal growth (via sciencedaily.com) Original source
Zika virus infection in pregnant rhesus macaques slows fetal growth and affects how infants and mothers interact in the first month of life, according to a new study. The work has implications for both humans exposed to Zika virus and for other viruses that can cross the placenta, including SARS-CoV2, responsible for the COVID-19 pandemic.
Published Sperm's secret voltage switch: Scientists unlock the mystery of motility (via sciencedaily.com) Original source
Researchers have unveiled the hidden intricacies of how sperm go from passive bystanders to dynamic swimmers. This transformation is a pivotal step in the journey to fertilization, and it hinges on the activation of a unique ion transporter.
Published New technology 'game changing' for pregnant women with diabetes (via sciencedaily.com) Original source
New research shows that automated insulin delivery technology could be a game changer for pregnant women with type 1 diabetes. The technology -- known as 'hybrid closed-loop technology' -- gives insulin doses as informed by a smartphone algorithm. The new study shows that it could help pregnant women better manager their blood sugars compared to traditional insulin pumps or multiple daily injections. Lead researcher Prof Helen Murphy from UEA said: 'This technology is game changing, in that it will allow more women to have safer, healthier, more enjoyable pregnancies, with potential for lifelong benefits for their babies.'
