Radiation Segmentectomy and Modified Radiation Lobectomy for Unresectable Early-Stage Intrahepatic Cholangiocarcinoma.

Purpose: To validate the safety and efficacy of radiation segmentectomy (RS) and modified radiation lobectomy (mRL) in intrahepatic cholangiocarcinoma (iCCA) and to evaluate long-term outcomes in patients with unresectable, early-stage iCCA.

Materials And Methods: A single-institution, retrospective study of patients with unresectable, solitary iCCA without extrahepatic disease or vascular involvement (stage I) treated with RS and mRL was performed. Fifteen patients met inclusion criteria (median age 65.

Yttrium-90 Radiation Segmentectomy for Treatment of Neuroendocrine Liver Metastases.

Purpose: To assess the safety and effectiveness of yttrium-90 (Y) radiation segmentectomy (RS) for neuroendocrine tumor liver metastases (NELMs).

Materials And Methods: This single-institution retrospective study included 18 patients with 23 liver tumors not amenable to resection or ablation, who underwent RS between 2009 and 2021. Tumor grades by Ki-67/mitotic indices were Grade I (n = 9/23, 39%), Grade II (n = 10/23, 45%), and Grade III (n = 4/23, 17%).

CT/MRI LI-RADS 2024 Update: Treatment Response Assessment.

With the rising incidence of hepatocellular carcinoma, there has been increasing use of local-regional therapy (LRT) to downstage or bridge to transplant, for definitive treatment, and for palliation. The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) Treatment Response Assessment (TRA) algorithm provides guidance for step-by-step tumor assessment after LRT and standardized reporting. Current evidence suggests that the algorithm performs well in the assessment of tumor response to arterial embolic and loco-ablative therapies and fair when assessing response to radiation-based therapies, with limited data to validate the latter.

Climate emotions, thoughts, and plans among US adolescents and young adults: a cross-sectional descriptive survey and analysis by political party identification and self-reported exposure to severe weather events.

Background: Climate change has adverse effects on youth mental health and wellbeing, but limited large-scale data exist globally or in the USA. Understanding the patterns and consequences of climate-related distress among US youth can inform necessary responses at the individual, community, and policy level.

Methods: A cross-sectional descriptive online survey was done of US youth aged 16-25 years from all 50 states and Washington, DC, between July 20 and Nov 7, 2023, via the Cint digital survey marketplace.

Impact of soluble epoxide hydrolase inhibition on silica-induced pulmonary fibrosis, ectopic lymphoid neogenesis, and autoantibody production in lupus-prone mice.

Objective: Acute intranasal (IN) instillation of lupus-prone NZBWF1 mice with crystalline silica (cSiO) triggers robust lung inflammation that drives autoimmunity. Prior studies in other preclinical models show that soluble epoxide hydrolase (sEH) inhibition upregulates pro-resolving lipid metabolites that are protective against pulmonary inflammation. Herein, we assessed in NZBWF1 mice how acute IN cSiO exposure with or without the selective sEH inhibitor TPPU influences lipidomic, transcriptomic, proteomic, and histopathological biomarkers of inflammation, fibrosis, and autoimmunity.
