Our objective was to investigate patient-reported maternal and perinatal outcomes and survival among women undergoing aortic valve and/or aortic root replacement (AVR/ARR). This was a single-center observational study of U.S.

Background: For children with HIV on antiretroviral therapy (ART), transitioning to dolutegravir-containing regimens is recommended. The aim of this study was to assess whether introducing viral load testing to inform new nucleoside or nucleotide reverse transcriptase inhibitors (NRTIs) for children with HIV and viraemia alongside dolutegravir-based ART is beneficial and of good economic value.

Methods: We used the Cost-Effectiveness of Preventing AIDS Complications-Pediatric model to project clinical and cost implications of three strategies among a simulated cohort of South African children aged 8 years with HIV receiving abacavir-lamivudine-efavirenz: (1) continue current ART (no dolutegravir; abacavir-lamivudine-efavirenz); (2) transition all children with HIV to dolutegravir, keeping current NRTIs (dolutegravir; abacavir-lamivudine-dolutegravir); or (3) transition to dolutegravir based on viral load testing (viral load plus dolutegravir), keeping current NRTIs if virologically suppressed (abacavir-lamivudine-dolutegravir, 70% of cohort) or switching abacavir to zidovudine (zidovudine) if viraemic (zidovudine-lamivudine-dolutegravir, 30%).

: Grade-2 gliomas (G2-glioma) are uncommon. In 2016, RTOG9802 established the addition of chemotherapy after radiation (CRT) as a new standard of care for patients with high-risk G2-glioma, defined as subtotal resection or age ≥40 yrs. Here, we report current practices using real-world data.

Article Synopsis
  • Identified noncoding driver mutations in pancreatic ductal adenocarcinoma (PDAC) by mapping accessible chromatin regions and histone modifications in pancreatic cell lines and tissues, integrating this data with whole-genome mutations from 506 PDAC cases.
  • *From 3,614 noncoding somatic mutations (NCSMs) found, 178 were shown to significantly affect gene activity, highlighting their potential role in cancer progression.
  • *Further experiments pinpointed specific genes impacted by these mutations, with a focus on one gene (KLF9) that showed reduced expression due to interference from NCSMs, establishing it as a possible PDAC driver gene.

Pancreatic Ductal Adenocarcinoma (PDAC) is the third leading cause of cancer-related deaths in the U.S. Both rare and common germline variants contribute to PDAC risk.
