Fatal acute pulmonary embolism following endoscopic cyanoacrylate injection for gastric fundal varices.

Acute gastric variceal bleeding is a rare but serious complication of portal hypertension. Initial therapy for bleeding gastric varices focuses on acute hemostasis. In this regard, endoscopic cyanoacrylate injection (ECI) is the first-line approach.

Emissions of HFC-23 do not reflect commitments made under the Kigali Amendment.

HFC-23 (trifluoromethane) is a potent greenhouse gas released to the atmosphere primarily as a by-product of HCFC-22 (chlorodifluoromethane) synthesis. Since 2020, the Kigali Amendment to the Montreal Protocol has required Parties to destroy their HFC-23 emissions to the extent possible. Here, we present updated HFC-23 emissions estimated from atmospheric observations.

Substantial increase in perfluorocarbons CF (PFC-14) and CF (PFC-116) emissions in China.

The perfluorocarbons tetrafluoromethane (CF, PFC-14) and hexafluoroethane (CF, PFC-116) are potent greenhouse gases with near-permanent atmospheric lifetimes relative to human timescales and global warming potentials thousands of times that of CO. Using long-term atmospheric observations from a Chinese network and an inverse modeling approach (top-down method), we determined that CF emissions in China increased from 4.7 (4.
