Results of a survey on peri-operative nutritional support in pancreatic and biliary surgery in Spain.

Introduction: a survey on peri-operative nutritional support in pancreatic and biliary surgery among Spanish hospitals in 2007 showed that few surgical groups followed the 2006 ESPEN guidelines. Ten years later we sent a questionnaire to check the current situation. Methods: a questionnaire with 21 items sent to 38 centers, related to fasting time before and after surgery, nutritional screening use and type, time and type of peri-operative nutritional support, and number of procedures.

Multivariate data analysis for the detection of human alpha-acid glycoprotein aberrant glycosylation in pancreatic ductal adenocarcinoma.

Relative quantification of human alpha-acid glycoprotein (hAGP) glycan isomers using [C]/[C]-aniline in combination with multivariate data analysis is proposed as an efficient method for the identification of pancreatic ductal adenocarcinoma (PDAC) glycan biomarkers in serum samples. Intact and desialylated glycans from hAGP, purified from serum samples of patients with PDAC and chronic pancreatitis (ChrP), were labeled with aniline and analyzed by μZIC-HILIC-MS. Afterwards, partial least squares discriminant analysis (PLS-DA) was applied to the relative areas obtained for all glycan isomers in the different samples: pathological (ChrP or PDAC) versus healthy samples.

Glycoprotein biomarkers for the detection of pancreatic ductal adenocarcinoma.

Pancreatic cancer (PaC) shows a clear tendency to increase in the next years and therefore represents an important health and social challenge. Currently, there is an important need to find biomarkers for PaC early detection because the existing ones are not useful for that purpose. Recent studies have indicated that there is a large window of time for PaC early detection, which opens the possibility to find early biomarkers that could greatly improve the dismal prognosis of this tumor.

Lethal intestinal perforation after foreign body ingestion in a superobese patient.

Accidental ingestion of foreign bodies is common in the general population. Most foreign bodies pass through the entire digestive tract without incidents. However, in some cases, the ingested foreign body can cause complications such as acute abdomen due to intestinal perforation and even death.

Incarcerated umbilical hernia in a super-super-obese patient.

Abdominal wall hernias are more prevalent in the morbidly obese. Incarceration of external hernias is a relatively common process in adults and is associated to a high rate of complications and mortality. We present the case of a morbidly super-super-obese patient (body mass index, 80 kg/m(2)) who underwent emergency surgery for an incarcerated umbilical hernia; the patient died despite segmental intestinal resection, hernia repair using mesh, and intensive care.
