A study published in Hepatology found that fewer than 20% of patients with cirrhosis and hepatocellular carcinoma received regular surveillance. Despite high-risk patients being recommended for HCC surveillance, population-based studies indicate only 11% are diagnosed early enough to receive potentially curative treatments.
A controlled trial suggests that a combination of band ligation and nadolol may not be the most effective prophylaxis for first variceal bleeding. Beta blockers are generally considered the treatment of choice for prophylaxis of first variceal bleeding.

The researchers found that when one partner expresses gratitude to the other, it strengthens their bond and fosters feelings of appreciation and connection. Conversely, indebtedness can hinder relationship maintenance.
