Effects of various statins on depressive symptoms: A network meta-analysis.

Background: Previous studies have indicated that statins can reduce the severity of depressive symptoms. However, the optimal choice of statin remains unclear. Therefore, we conducted a network meta-analysis to determine the optimal statin for treating depression.

Serum leptin levels in preterm, healthy and sick-term newborns.

Leptin, a hormone that signals the brain about the status of body (fat) energy stores, has recently been shown to play a role in the regulation of several hypothalamic pituitary axes, including the growth hormone axis. To investigate a potential association of serum leptin concentrations and clinical condition in preterm, sick term and healthy term newborns, serum leptin concentrations were evaluated in 104 newborns. Twenty-eight of them were healthy term (18 males and 10 females; gestational age, 37-42 weeks), 21 were sick term (12 males and 9 females; gestational age, 37-42 weeks) and 55 were preterm neonates (35 males and 20 females; gestational age: 26-37 weeks).
