Risk prediction of complicated course in patients undergoing major head and neck surgery with free flap reconstruction.

The British Association of Oral and Maxillofacial Surgeons (BAOMS) Quality and Outcomes in Oral and Maxillofacial Surgery (QOMS) reconstructive audit aims to provide surgical teams with risk adjusted comparative performance data. The goal is to enable surgeons to optimise surgical pathways. Risk adjustment requires that data on appropriate predictive variables are collected.

Body composition at birth and its relationship with neonatal anthropometric ratios: the newborn body composition study of the INTERGROWTH-21 project.

BackgroundWe aimed to describe newborn body composition and identify which anthropometric ratio (weight/length; BMI; or ponderal index, PI) best predicts fat mass (FM) and fat-free mass (FFM).MethodsAir-displacement plethysmography (PEA POD) was used to estimate FM, FFM, and body fat percentage (BF%). Associations between FFM, FM, and BF% and weight/length, BMI, and PI were evaluated in 1,019 newborns using multivariate regression analysis.

Precision of recumbent crown-heel length when using an infantometer.

Background: Crown-heel length (CHL) measurement is influenced by technique, training, experience and subject cooperation. We investigated whether extending one or both of an infant's legs affects the precision of CHL taken using an infantometer. The influence of staff training and infant cooperation were also examined.
