Objective:
To evaluate pancreatic stone protein (PSP) levels in extremely preterm neonates and their association with early-onset sepsis (EOS), late-onset sepsis (LOS), and necrotizing enterocolitis (NEC).
Study Design:
A prospective longitudinal study, evaluating serial PSP, C-reactive protein (CRP), and white blood cell (WBC) count during the first ten days after birth.
Results:
Thirty extremely preterm neonates with a mean gestational age of 26.5 ± 1.8 weeks and a mean birth weight of 890 ± 304 g were enrolled. PSP increased significantly 48 h before LOS presentation, with a diagnostic accuracy higher than that of CRP and WBC (AUROC 0.711, 0.567, and 0.538, respectively). PSP levels also increased from 72 h before NEC onset, with a better discriminatory ability than CRP and WBC (AUROC 0.851, 0.648, and 0.616, respectively).
Conclusion:
PSP may represent a promising early biomarker for LOS and NEC in extremely preterm neonates. Larger multicenter studies are required to validate these findings.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
