Hourly weather data reveals climate trends in U.S.

A new study by NC State University researchers found that areas in the northeastern US have lost nearly 1.5 weeks of temperatures below freezing, while regions like Arizona gained almost 1.5 weeks of temperatures above 86F. This data can help inform climate adaptation planning and justify changes to address regional climate change.

The mechanisms behind thrombocytopenia in patients with portal hypertension and chronic liver disease

Thrombocytopenia is a hallmark of portal hypertension and cirrhosis, with impaired production, increased destruction, and sequestration being key mechanisms. Diagnostic approaches include non-invasive methods like transient elastography and serological markers, while integrated management addresses both PH and thrombocytopenia.
