Purpose To compare visual versus quantitative ablation confirmation for identifying local tumor progression and residual tumor following microwave ablation (MWA) of colorectal liver metastases (CRLM). Materials and Methods This retrospective study included patients undergoing MWA of CRLM from October 2014 to February 2018. Two independent readers visually assessed pre- and postprocedure images and semiquantitatively scored for incomplete ablation, using a six-point Likert scale, and extracted quantitative imaging metrics of minimal ablative margin (MAM) and percentage of tumor outside of the ablation zone, using both rigid and deformable registration.

The gold standard for detecting the presence of apneic events is a time and effort-consuming manual evaluation of type I polysomnographic recordings by experts, often not error-free. Such acquisition protocol requires dedicated facilities resulting in high costs and long waiting lists. The usage of artificial intelligence models assists the clinician's evaluation overcoming the aforementioned limitations and increasing healthcare quality.

Article Synopsis
  • - PARP inhibitors show promise in treating castration-resistant prostate cancer (CRPC) with homologous recombination repair (HRR) defects, but the reasons behind resistance are not completely understood.
  • - A study from the TOPARP-B trial found that 79% of BRCA2/PALB2-mutated tumors exhibited reversion mutations at the end of treatment, with many related to POLQ-mediated DNA repair mechanisms.
  • - In cases of BRCA2 homozygous deletions, rare subclones lacking the BRCA2 deletion are selected for after PARP inhibitor treatment, indicating the necessity for restored HRR function in developing resistance.

Objective: To estimate the association between the mode of respiratory support administered at 36 weeks' post-menstrual age (PMA) with time-to-liberation from respiratory support (LRS) in infants with grade 2/3 bronchopulmonary dysplasia (BPD).

Study Design: Daily respiratory support data were abstracted for infants born <32 weeks' gestation with grade 2/3 BPD enrolled in the Children's Hospitals Neonatal Database between 2017 and 2022. The main exposure was the mode of respiratory support received at 36 weeks' PMA: high flow nasal cannula >2 L/min (HFNC), continuous positive airway pressure (CPAP), non-invasive positive pressure ventilation (NIPPV), or mechanical ventilation (MV).

Objective: To evaluate associations between neonatal risk factors and pulmonary vein stenosis (PVS) among infants born preterm with severe bronchopulmonary dysplasia (sBPD).

Study Design: We performed a case-control study of infants born from 2010 to 2022 at <32 weeks' gestation with sBPD among 46 neonatal intensive care units in the Children's Hospitals Neonatal Consortium. Cases with PVS were matched to controls using epoch of diagnosis (2010-2016; 2017-2022) and hospital.
