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 Mice eating less of specific amino acid -- overrepresented in diet of obese people -- live longer, healthier (via sciencedaily.com) Original source
A new study in mice shows that cutting down the amount of a single amino acid called isoleucine can, among other benefits, extend their lifespan, make them leaner and less frail as they age and reduce cancer and prostate problems, all while the mice ate more calories.
Published Nutrient found in beef and dairy improves immune response to cancer (via sciencedaily.com) Original source
Trans-vaccenic acid (TVA), a long-chain fatty acid found in meat and dairy products from grazing animals such as cows and sheep, improves the ability of CD8+ T cells to infiltrate tumors and kill cancer cells, according to a new study.
Published Study reveals surprising link between malnutrition and rising antibiotic resistance (via sciencedaily.com) Original source
Researchers have uncovered startling connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe. The team investigated how deficiencies in crucial micronutrients such as vitamin A, B12, folate, iron, and zinc affected the community of bacteria, viruses, fungi and other microbes that live in the digestive system. They discovered that these deficiencies led to significant shifts in the gut microbiome of mice -- most notably an alarming expansion of bacteria and fungi known to be opportunistic pathogens. Importantly, mice with micronutrient deficiencies also exhibited a higher enrichment of genes that have been linked to antibiotic resistance.
Published Wearables capture body sounds to continuously monitor health (via sciencedaily.com) Original source
From heart beats to stomach gurgles, sounds hold important health information. New wireless devices sit on skin to continuously capture these sounds, then stream data to smartphones or tablets in real time. In pilot studies, devices accurately tracked sounds associated with cardiorespiratory function, gastrointestinal activity, swallowing and respiration. The devices are particularly valuable for premature babies, who can experience apneas and gastrointestinal complications, which are accompanied by sounds.
Published Vitamin B12: A key player in cellular reprogramming and tissue regeneration (via sciencedaily.com) Original source
Researchers reveal that vitamin B12 significantly boosts the efficiency of cellular reprogramming, thus holding promise for regenerative medicine. Vitamin B12 supplementation shows potential in speeding up tissue repair in a model of ulcerative colitis -- an observation that points to potential new treatments for inflammatory diseases.
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 Delaying cord clamping could halve risk of death in premature babies (via sciencedaily.com) Original source
Two new studies have given further weight to the benefits of delayed cord clamping, finding waiting for at least 2 minutes to clamp the umbilical cord of premature babies at birth could decrease the child's risk of death.
Published New compound outperforms pain drug by indirectly targeting calcium channels (via sciencedaily.com) Original source
A compound -- one of 27 million screened in a library of potential new drugs -- reversed four types of chronic pain in animal studies, according to new research. The small molecule, which binds to an inner region of a calcium channel to indirectly regulate it, outperformed gabapentin without troublesome side effects, providing a promising candidate for treating pain.
Published Team creates synthetic enzymes to unravel molecular mysteries (via sciencedaily.com) Original source
A bioengineer has developed synthetic enzymes that can control the behavior of the signaling protein Vg1, which plays a key role in the development of muscle, bone and blood in vertebrate embryos. The team of researchers is using a new approach, called the Synthetic Processing (SynPro) system, in zebrafish to study how Vg1 is formed. By learning the molecular rules of signal formation in a developing animal, researchers aim to engineer mechanisms -- such as giving cells new instructions -- that could play a role in treating or preventing disease.
Published Umbilical cord milking appears to be safe in preterm infants born after 28 weeks (via sciencedaily.com) Original source
A treatment to move blood from the umbilical cord into an infant's body may provide a safe option for preterm infants born after 28 weeks who need rapid support, suggests a new study. The procedure, called umbilical cord milking, involves gently squeezing the cord between the thumb and forefinger and pushing the blood into the newborn's abdomen. The new findings suggest that concerns raised by a 2019 study of infants born before 28 weeks -- which concluded that umbilical cord milking might increase the risk of bleeding inside the brain -- do not apply to preterm infants born after 28 weeks.
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 Reducing vitamin B5 slows breast cancer growth in mice (via sciencedaily.com) Original source
Researchers have discovered that breast cancer cells expressing a cancer-driving gene heavily rely on vitamin B5 to grow and survive.
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 Antibiotics for common childhood infections no longer effective (via sciencedaily.com) Original source
Alarmingly high rates of bacterial resistance to commonly prescribed antibiotics used to treat children and babies has been found in the Asia-Pacific.
Published Selenium reduces mixtures of environmental pollutants' harmful effects on health (via sciencedaily.com) Original source
