. The study aims to reduce the imaging radiation dose in Adaptive Radiotherapy (ART) while maintaining high-quality CT images, critical for effective treatment planning and monitoring.. We developed the Prior-aware Learned Primal-Dual Network (pLPD-UNet), which uses prior CT images to enhance reconstructions from low-dose scans. The network was separately trained on thorax and abdomen datasets to accommodate the unique imaging requirements of each anatomical region.. The pLPD-UNet demonstrated improved reconstruction accuracy and robustness in handling sparse data compared to traditional methods. It effectively maintained image quality essential for precise organ delineation and dose calculation, while achieving a significant reduction in radiation exposure.. This method offers a significant advancement in the practice of ART by integrating prior imaging data, potentially setting a new standard for balancing radiation safety with the need for high-resolution imaging in cancer treatment planning.

Importance: Semaglutide, a novel glucagon-like peptide-1 (GLP-1) receptor agonist medication, was approved for weight management in individuals with obesity in June 2021. There is limited evidence on factors associated with uptake among individuals in this subgroup without diabetes.
Objective: To explore factors associated with semaglutide initiation among a population of commercially insured individuals with obesity but no diagnosed diabetes.

Importance: Timely access to care is a key metric for health care systems and is particularly important in conditions that acutely worsen with delays in care, including surgical emergencies. However, the association between travel time to emergency care and risk for complex presentation is poorly understood.
Objective: To evaluate the impact of travel time on disease complexity at presentation among people with emergency general surgery conditions and to evaluate whether travel time was associated with clinical outcomes and measures of increased health resource utilization.

Purpose: Mesothelin (MSLN) is highly expressed in high grade serous/ endometrioid ovarian cancers (HGOC). Anetumab ravtansine (AR) is an antibody drug conjugate directed at MSLN antigen with a tubulin polymerization inhibitor. We assessed safety, activity and pharmacokinetics of the combination AR/bevacizumab (Bev) (ARB) versus weekly paclitaxel (wP)/Bev (PB) in patients with platinum resistant/refractory HGOC (prrHGOC).

Purpose: To review recent advances with radiation therapy (RT) for soft tissue sarcomas (STS).
Recent Findings: Newer data showcases hypofractionated preoperative RT for soft tissue sarcomas treated with surgery to be safe and effective, however, long-term follow up data is pending. Hypofractionated and dose-escalated RT in patients with unresectable STS is also being studied, for which we remain optimistic given advances in RT planning approaches.

This article provides a comprehensive overview of the current treatment options for patients with metastatic castration-resistant prostate cancer (mCRPC) following the failure of first-line therapy. Although significant progress has been made in the primary treatment of hormone-sensitive prostate cancer, the management of mCRPC remains a clinical challenge. The article outlines the diagnostic criteria for mCRPC, which can be confirmed through biochemical progression and imaging techniques.
