The study estimated that a loss of access to wildlife as a food source would lead to a 29% increase in child anemia.
Researchers suggest that transfusion may not be the best treatment for hospitalized patients with anemia, as the age of stored blood may contribute to negative effects. Studies found that transfusions do not always restore levels of sphingosine 1-phosphate (S1P), a lipid mediator required for maintaining blood vessel integrity.
Researchers analyzed SEC23B gene mutations in CDA II patients and found that two variants, R14W and E109K, are more common in Italian population. The R14W variant is believed to have originated 3,000 years ago in Southern Italy, while E109K may have originated in the Middle East around 2,400 years ago.

The research suggests that monitoring a pregnant woman's iron status beyond anemia is crucial.
Researchers at UTHealth discovered that children with asymptomatic H. pylori infections have lower iron levels compared to those without the infection. The study found that even in healthy children, the bacterium causes a decrease in iron storage, which may have long-term health consequences.
