Clinical Validation of a Deep-Learning Segmentation Software in Head and Neck: An Early Analysis in a Developing Radiation Oncology Center.

Background: Organs at risk (OARs) delineation is a crucial step of radiotherapy (RT) treatment planning workflow. Time-consuming and inter-observer variability are main issues in manual OAR delineation, mainly in the head and neck (H & N) district. Deep-learning based auto-segmentation is a promising strategy to improve OARs contouring in radiotherapy departments.

Dosimetric Impact of Inter-Fraction Variability in the Treatment of Breast Cancer: Towards New Criteria to Evaluate the Appropriateness of Online Adaptive Radiotherapy.

Purpose: As a discipline in its infancy, online adaptive RT (ART) needs new ontologies and criteria to evaluate the appropriateness of its use in clinical practice. In this experience, we propose a predictive model able to quantify the dosimetric impact due to daily inter-fraction variability in a standard RT breast treatment, to identify in advance the treatment fractions where patients might benefit from an online ART approach.

Methods: The study was focused on right breast cancer patients treated using standard adjuvant RT on an artificial intelligence (AI)-based linear accelerator.

Predicting respiratory distress syndrome in neonates from mothers with intrahepatic cholestasis of pregnancy.

Objective: Intrahepatic cholestasis of pregnancy (ICP) has been associated with prematurity and fetal mortality. Recently, ICP has also been recognised as a risk factor for neonatal respiratory distress syndrome (RDS) in term or near-term neonates. Since fetal mortality is more frequent in pregnancies with an early ICP onset, we speculated that the time of exposure (ET) to maternal bile acids at the delivery (BAdeliv) could be involved in neonatal lung damage too.

Delivery room strategies and outcomes in preterm infants with gestational age 24-28 weeks.

Objective: To investigate the effect of different delivery room strategies on survival, short term morbidity, and outcomes in extremely premature infants.

Methods: This retrospective cohort study included all preterm infants with a gestational age between 24 and 28 weeks who were born in 1992-1997 (period A; n = 161) and in 1998-2003 (period B; n = 163). In period A, elective intubation was performed.

Using BiliCheck for preterm neonates in a sub-intensive unit: diagnostic usefulness and suitability.

Background: BiliCheck (BC), a new transcutaneous bilirubinometer is thought to be lacking in the disadvantages of old devices and could be potentially useful for diagnosing jaundice in preterm babies. Although its accuracy is well known in healthy term babies, there is a lack of knowledge about its usefulness in preterm infants.

Aims: To investigate BC usefulness in preterm babies and its suitability in a sub-intensive neonatal unit.

Intrahepatic cholestasis of pregnancy and neonatal respiratory distress syndrome.

Objectives: We sought to verify the association between maternal intrahepatic cholestasis of pregnancy (ICP) and neonatal respiratory distress syndrome (RDS) and to determine how bile acids levels alter the risk of developing neonatal RDS.

Methods: We extracted data from our divisional database about all of the newborns born during the years 2000-2004. We compared 77 neonates born from pregnancies complicated by ICP with 427 neonates in the same range of gestational age born from noncomplicated pregnancies.
