The Lancet: New study reveals global anemia cases remain persistently high among women and children. Anemia rates decline for men.

A new study reveals that nearly 2 billion people worldwide suffer from anemia, with women and children disproportionately affected. Anemia rates have declined among men, but progress has been slow for women and children, driven by factors such as access to nutrition, socioeconomic status, and unmet need for contraception.

New study findings underscore the importance of timely newborn screenings in early care for cystic fibrosis

A new study by Dr. Stacey Martiniano found that late diagnosis of cystic fibrosis due to delays in evaluation after a positive newborn screen test results in poorer long-term nutritional outcomes, including reduced weight-for-age and height-for-age. Early initiation of CF care is essential to improve health outcomes in infants with CF.
