Intrafraction Patient Positional Uncertainty in Lung Stereotactic Ablative Radiotherapy with Abdominal Compression.

Purpose: Motion management presents a significant challenge in thoracic stereotactic ablative radiotherapy (SABR). Currently, a 5.0 mm standard planning target volume (PTV) margin is widely used to ensure adequate dose to the tumor.

Hyperinsulinemic hypoglycemia in growth restricted convalescent preterm neonates: clinical characteristics and impediments to early diagnosis.

Objectives: Describe clinical characteristics, course, and risk factors for hyper-insulinemic hypoglycemia (HIH) in preterm infants and identify impediments to early diagnosis.

Methods: Electronic records of infant-mother dyads were used to describe clinical characteristics, lab parameters, and course of HIH.

Results: All eight patients (gestational ages 26w0d-29w3d) had intrauterine growth restriction (IUGR) due to placental insufficiency, (4/8) were small for gestational age.
