In this paper we investigate whether infant and childhood feeding practices influenced the imbalanced adult sex ratio reported in medieval Europe from historical and osteological evidence. First, we examine hypotheses for the observed imbalanced sex ratios in Europe and the evidence presented to support these hypotheses. We then use stable isotope analysis (δ13C and δ15N) of incremental dentine in 64 first molars from adults at three medieval sites (Aulla, Badia Pozzeveri, and Montescudaio) in north-western Tuscany (11th-15th c. CE).
Coro, a new device created by Coroflow, accurately monitors breast milk intake in real-time, down to the 0.1 milliliters -- the first product on the market to do so. Coro is a silicone nipple shield with a patented micro-flow meter that measures milk intake, which you can view in an app. The app translates the data into insights on breast milk volume and feeding trends for each breast to help new parents better understand their baby's feeding patterns.
These figures matter because breast milk is more than a source of calories. It maintains the ideal balance of nutrients while delivering a vast array of bioactive compounds that shape your child's growth and development. Among these compounds are human milk oligosaccharides (HMOs), complex sugars that rank as the third most abundant solid component in breast milk, surpassed only by lactose and lipids.
Lydia* first started thinking about weight-loss drugs during pregnancy. Everyone was talking about them and the advertisements were everywhere, she says, as her baby son naps upstairs. I remember thinking: That's how I'll lose weight for my wedding next year.' When Lydia explains that most of her life before pregnancy was spent in a welter of yo-yo dieting and body dissatisfaction, I say to her that I think most of us can relate.
Parity and breastfeeding reduce the risk of breast cancer, particularly triple-negative breast cancer (TNBC)1,2, yet the immunological mechanisms underlying this protection remain unclear. Here, we show that parity induces an accumulation of CD8+ T cells, including cells with a tissue-resident memory (TRM)-like phenotype within human normal breast tissue. In murine models, pregnancy followed by lactation and involution drove the accumulation of CD8 T
