A study in the Annals of Surgery found that women with morbid obesity who underwent bariatric surgery had a 37% lower breast cancer risk over an average of about 48 months, compared with those who did not undergo the procedure. The study of 71,887 women found that the risk of developing breast cancer was reduced by 45% after menopause and 28% before menopause.
A study associated breastfeeding with lower risk of cardiovascular disease and its risk factors for women later in life, researchers told the European Society of Endocrinology's annual meeting. The study also found that the longer a woman breastfeeds, the lower the risk.
A study in Menopause showed that postmenopausal women who had at least four pregnancies were at a 28% higher likelihood of developing diabetes than those who gave birth two or three times, with results persisting after adjusting for age, age at menarche and at menopause, body mass index, race and use of hormone therapy. Chinese researchers used a cohort of 9,138 postmenopausal women with no history of gestational diabetes and found that those with at least four pregnancies had higher levels of HbA1C, fasting plasma glucose and two-hour plasma glucose and were more insulin resistant, compared with women who had two to three pregnancies.
Psoriatic arthritis or ankylosing spondylitis are associated with increased risk of adverse pregnancy and obstetric events, according to a study in Arthritis Care & Research. Women with psoriatic arthritis were at higher risk of moderate preterm birth, while those with ankylosing spondylitis had a greater likelihood of having an infant hospitalized in the neonatal intensive care unit.
The number of babies born with low birth weight worldwide dropped from 22.9 million in 2000 to 20.5 million in 2015, a 1.2% annual rate of decline, according to a report from the World Health Organization, UNICEF and the London School of Hygiene & Tropical Medicine in The Lancet Global Health. However, researcher Joy Lawn said that the 30% targeted reduction in global low birth weight prevalence by 2025 could only be achieved by expediting the rate of decline by more than twofold.
Hospital NICUs this week celebrated International Kangaroo Care Day and raised awareness of the benefits of skin-to-skin contact between parents and infants. "Skin to skin is very important -- it can help bring a mom's milk in, it can regulate a baby's heartbeat, their respiratory rate, their temperature. It's super important for bonding for families," said NICU nurse Cari Snaza.
A study in the Journal of Maternal-Fetal & Neonatal Medicine showed that babies whose mothers took opioids during pregnancy had greater skin conductance scores during and after a heel-stick test. Facial distress was higher before the procedure, suggesting greater behavioral distress and increased self-soothing difficulties, among opioid-exposed infants.
