Endocrine-disrupting chemicals may influence hormonal shifts during pregnancy as well as contribute to postpartum depression, according to a small study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
New research by the National Institutes of Health found that unbalanced progesterone signals may cause some pregnant women to experience preterm labor or prolonged labor. The study in mice — published online in the Proceedings of the National Academy of Sciences — provides novel insights for developing treatments.
Weizmann Institute scientists analyzed around six million blood tests to obtain data on several types of hormones, discovering that some peak in winter/spring and others in summer. Peaks in stress or reproductive hormones may have “evolved to help us cope with seasonal changes in our surrounding environment.”
Drinks with sucrose compared to glucose may cause young adults to produce lower levels of appetite-regulating hormones, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
During birth, hormones in the body surge in both mother and baby, sent along by the nervous system. These stress hormones are there to spur delivery and to help a baby adapt to living outside the womb. A new study finds how one is born can have an effect on the amount of stress hormones released at the time of delivery. For example, vaginal delivery had the highest presence of birth signaling hormones.
Middle-aged women are more likely than men to have changes in the brain related to Alzheimer’s disease, as detected by imaging, even when there are no differences in thinking and memory. This may be associated with hormonal changes due to menopause, specifically the loss of estrogen, according to a study published in the June 24, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Mount Sinai researchers have for the first time identified reproductive and metabolic subtypes of polycystic ovary syndrome (PCOS) that are associated with novel gene regions.
Fatherhood looks very different across species. Tiny stickleback fish are especially involved in raising their young, and along with other animals, they’re showing us the impact paternal care can have on both offspring and fathers.
A new Weizmann Institute model of autoimmune disease may solve some major outstanding riddles, including what causes T cells to attack and why only certain organs get the diseases
UCLA researchers have launched a new clinical trial that uses a hormone suppresser commonly used to treat men with prostate cancer to help improve clinical outcomes for men infected with COVID-19.
As the world prioritizes social distancing due to COVID-19, new research shows that extended use of Kangaroo Care, a skin-to-skin, chest-to-chest method of caring for a baby, can positively benefit full-term infants and their mothers, which has important implications for post-partum depression. The study provides evidence that the physiology of mothers and their full-term infants is influenced by Kangaroo care: it increases oxytocin levels in mothers, and during infancy, can favorably influence both neurodevelopmental trajectories and infant neurobiological functioning.
New research in rats suggests sex hormones and age play a role in dehydration differences in men and women. The study is published in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology.
When the thyroid and parathyroid glands don’t work well, the entire body feels out of balance. To tackle thyroid and parathyroid diseases, Nathan Boyd, MD, recently launched the UNM Thyroid and Parathyroid Surgery Program, housed at the UNM Comprehensive Cancer Center, to offer state-of-the-art treatments for these diseases.
At a glance:
Experiments in worms reveal the molecular damage caused by DEHP, a chemical commonly used to make plastics flexible
DEHP interferes with proper cell division during egg formation, leads to excessive DNA breakage, alters chromosome appearance
Abnormalities help explain known link between DEHP and human birth defects, male infertility
If replicated in further research, the insights can help inform regulatory changes, consumer choice
Recent study found that an effective blood cancer treatment was associated with weight gain, obesity, and increased systolic blood pressure
