Second-line treatment patterns and outcomes in advanced HCC after progression on atezolizumab/bevacizumab.

Background & Aims: Atezolizumab/bevacizumab (A/B) is now a standard first-line treatment for advanced hepatocellular carcinoma (HCC), but the optimal second-line regimen is not known. We evaluated real-world treatment patterns and outcomes to investigate factors associated with post-progression survival (PPS).

Methods: In this multicenter, international, retrospective study, we examined clinical characteristics and outcomes of patients with advanced HCC who progressed on first-line A/B.

Oropharyngeal Lymphogranuloma Venereum: A Clinical Reasoning Challenge and Literature Review.

Lymphogranuloma venereum (LGV) is a sexually transmitted infection typically caused by serovars L1-L3 of . These serovars are tissue-invasive with a preponderance for lymphatic spread and can be acquired via unprotected oral, anal, or vaginal sex. We present the case of a 23-year-old with a prior history of syphilis admitted with four weeks of progressively enlarging painful right cervical lymphadenopathy.

Nontarget screening of a Siberian ice core reveals changes in the pre-industrial to industrial organic aerosol composition.

Glaciers serve as natural archives for reconstructing past changes of atmospheric aerosol concentration and composition. While most ice-core studies have focused on inorganic species, organic compounds, which can constitute up to 90% of the submicrometer aerosol mass, have been largely overlooked. To our knowledge, this study presents the first nontarget screening record of secondary organic aerosol species preserved in a Belukha ice core (Siberia, Russian Federation), ranging from the pre-industrial to the industrial period (1800-1980 CE).
