Surgery for intraductal papillary mucinous neoplasms in young patients: High-risk population.

Background: Intraductal papillary mucinous neoplasms of the pancreas are uncommon in young individuals. Management of these patients is challenging because the risk of malignancy and recurrence after surgery remains unclear. The aim of the present study was to assess the long-term risk for intraductal papillary mucinous neoplasm recurrence after surgery for intraductal papillary mucinous neoplasms in patients ≤50 years of age.

Silica fertilization improved wheat performance and increased phosphorus concentrations during drought at the field scale.

Drought and the availability of mineable phosphorus minerals used for fertilization are two of the important issues agriculture is facing in the future. High phosphorus availability in soils is necessary to maintain high agricultural yields. Drought is one of the major threats for terrestrial ecosystem performance and crop production in future.
