US Evaluation of Bone Age in Rural Ecuadorian Children: Association with Anthropometry and Nutrition.

Background Stunted growth and development is a serious global public health problem. A limited number of field measures exist that can be used to evaluate stunting and its underlying biologic mechanisms. Purpose To assess bone age using tablet-based US in young children living in a rural community in Ecuador, where stunting is prevalent, and to evaluate the associations between bone age, anthropometry, and diet.

Egg intervention effect on linear growth no longer present after two years.

The Lulun Project, a randomized controlled trial conducted in 2015, found that one egg per day for 6 months during early complementary feeding reduced stunting by 47% and increased linear growth by 0.63 length-for-age Z (LAZ). This follow-up cohort study (Lulun Project II) aimed to test whether the growth effect remained in the egg intervention group compared with the control group after approximately 2 years.

Breast cancer stage variation and survival in association with insurance status and sociodemographic factors in US women 18 to 64 years old.

Background: Few population-based studies have examined the association between health insurance status and breast cancer stage at diagnosis and survival. The degree to which sociodemographic characteristics explain this association is also unclear. This study examined associations between insurance status and sociodemographic characteristics and stage at diagnosis and survival.
