Prevalence and Characteristics of Infant's Unexplained Breast Preference for Nursing One Breast: A Self-Administered Survey.

Background: Breastfeeding is recommended by international bodies as the only source of infant nutrition during the first 6 months of life. Sometimes infants prefer to nurse on one breast for no obvious reason (hereafter called infant's unexplained breast preference [IUBP]). IUBP might reduce the rate of exclusive breastfeeding.

A Systematic Review and Meta-analysis of the Timing of Early Intraventricular Hemorrhage in Preterm Neonates: Clinical and Research Implications.

A considerable number of intraventricular hemorrhages (IVH) occur within the first hours of life (HOL). Temporality between IVH and its antecedents as well as a consistent definition of "early IVH" is lacking in a large and growing body of literature. We performed a systematic review of prospective studies that reported onset of IVH in preterm neonates within the first HOL and afterwards.
