Clinical significance of postoperative complications after pancreatic surgery in time-to-complication and length of postoperative hospital stay: a retrospective study.

Purpose: We retrospectively analyzed pancreatectomy patients and examined the occurrence rate and timing of postoperative complications (time-to-complication; TTC) and their impact on the length of postoperative hospital stay (POHS) to clarify their characteristics, provide appropriate postoperative management, and improve short-term outcomes in the future.

Methods: A total of 227 patients, composed of 118 pancreaticoduodenectomy (PD) and 109 distal pancreatectomy (DP) cases, were analyzed. We examined the frequency of occurrence, TTC, and POHS of each type of postoperative complication, and these were analyzed for each surgical procedure.

Estimation of nutrient excretion factors of broiler and layer chickens in Japan.

We estimated the nitrogen (N), phosphorus (P), potassium (K) and magnesium (Mg) excretion factors of broiler and layer chickens in Japan, using two approaches and the latest data available. In the top-down approach, we determined the nutrient amounts in the feeds and those in the products (i.e.

Pole and global shape of 25143 Itokawa.

The locations of the pole and rotation axis of asteroid 25143 Itokawa were derived from Asteroid Multiband Imaging Camera data on the Hayabusa spacecraft. The retrograde pole orientation had a right ascension of 90.53 degrees and a declination of -66.
