Adjunct mucin biomarkers MUC2+MUC5AC and MUC5AC+PSCA in a clinical setting identify and may improve correct selection of high-risk pancreatic lesions for surgery.

Background: Pancreatic cancer has dismal prognosis with a 5-year survival of 12 %. Cystic lesions have been identified as premalignant lesions. The challenge is to identify lesions with high risk of malignant progression, to offer patients prophylactic curative pancreatic surgery.

A randomized translational study on protein- and glucose metabolism in skeletal muscles evaluated by gene-ontology, following preoperative oral carbohydrate loading compared to overnight peripheral parenteral nutrition (PPN) before major cancer surgery.

Background: Effects of preoperative drinks on muscle metabolism are unclear despite general recommendations. The aim of the present study was therefore to compare metabolic effects of a preoperative oral nutrition drink, recommended by protocols for enhanced recovery after surgery (ERAS), compared to overnight preoperative peripheral total parenteral nutrition (PPN) on skeletal muscle metabolism in patients aimed at major gastrointestinal cancer surgery.

Methods: Patients were randomized, based on diagnosis and clinical characteristics, to receive either a commercial carbohydrate-rich nutrition drink (Drink); or overnight (12 h) peripheral parenteral nutrition (PPN) as study regimens; compared to isotone Ringer-acetate as Control regimen.

Acute appendicitis: A block-randomized study on active observation with or without antibiotic treatment.

Background: Antibiotic treatment of unselected patients with acute appendicitis is safe and effective. However, it is unknown to what extent early provision of antibiotic treatment may represent overtreatment due to spontaneous healing of appendix inflammation. The aim of the present study was to evaluate the role of antibiotic treatment versus active in-hospital observation on spontaneous regression of acute appendicitis.

A comprehensive review of pancreatic cancer and its therapeutic challenges.

Pancreatic cancer is a devastating and lethal human malignancy with no curable chemo-treatments available thus far. More than 90% of pancreatic tumors are formed from ductal epithelium as pancreatic ductal adenocarcinoma (PDAC), which often accompany with the expression of mutant . The incidences of pancreatic cancer are expected to increase rapidly worldwide in the near future, due to environmental pollution, obesity epidemics and etc.

Genetics and Therapeutic Responses to Tumor-Infiltrating Lymphocyte Therapy of Pancreatic Cancer Patient-Derived Xenograft Models.

Background And Aims: Pancreatic cancer is the seventh leading cause of cancer-related deaths worldwide. Checkpoint immunotherapy has not yet shown encouraging results in pancreatic cancer possibly because of a poor immunogenicity and/or an immune suppressive microenvironment. The aim of this study was to develop patient-derived xenograft (PDX) models, compare their genetics to the original biopsies, and assess if autologous tumor-infiltrating lymphocytes (TILs) would have antitumoral activity in pancreatic cancer.

Reduced tumor growth in EP2 knockout mice is related to signaling pathways favoring an increased local anti‑tumor immunity in the tumor stroma.

Inflammatory signaling through prostaglandin E2 receptor subtype 2 (EP2) is associated with malignant tumor growth in both experimental models and cancer patients. Thus, the absence of EP2 receptors in host tissues appears to reduce tumor growth and systemic inflammation by inducing major alterations in gene expression levels across tumor tissue compartments. However, it is not yet well‑established how signaling pathways in tumor tissue relate to simultaneous signaling alterations in the surrounding tumor‑stroma, at conditions of reduced disease progression due to decreased host inflammation.

High expression of p62/SQSTM1 predicts shorter survival for patients with pancreatic cancer.

Background: Accumulation of the signal adaptor protein p62 has been demonstrated in many forms of cancer, including pancreatic ductal adenocarcinoma (PDAC). Although data from experimental studies suggest that p62 accumulation accelerates the development of PDAC, the association between p62 protein expression and survival in PDAC patients is unclear.

Methods: Thirty-three tumor specimens from PDAC patients treated by primary surgery were obtained.

Risk factors for postoperative myocardial infarct following cholecystectomy: a population-based study.

Background: The aim was to analyse the risk for myocardial infarction (MI) after cholecystectomy.

Methods: The study is based on data from the Swedish Register for Gallstone Surgery (GallRiks) 2006-2014. The cohort was cross-linked with the Swedish Patient Register.

EGFR, but not COX-2, protein in resected pancreatic ductal adenocarcinoma is associated with poor survival.

The effects of EGFR and COX-2 protein overexpression on clinical outcomes in pancreatic ductal adenocarcinoma (PDAC) patients remains unclear. Therefore, the aim of the present study was to evaluate the protein expression of epithelial growth factor receptor (EGFR) and cyclooxygenase-2 (COX-2) in tumor cells in surgically resected PDAC, in comparison with clinicopathological characteristics and clinical outcomes. Immunohistochemical staining of formalin-fixed paraffin-embedded tissue derived from surgically resected tumors was performed.

Fractional uptake of circulating tumor cells into liver-lung compartments during curative resection of periampullary cancer.

Circulating tumor cells (CTCs) are able to predict outcome in patients with breast, colon and prostate cancer and appear to be promising biomarkers of pancreatic carcinoma. The aim of the present study was to demonstrate a statistically significant portal-arterial difference of CTCs during curative resection of periampullary cancer. A commercially available instrument (Isoflux) was used to quantify blood content of CTC in 10 patients with periampullary cancer according to preoperative diagnostics.

Overnight Steady-State Infusions of Parenteral Nutrition on Myosin Heavy Chain Transcripts in Rectus Abdominis Muscle Related to Amino Acid Transporters, Insulin-like Growth Factor 1, and Blood Amino Acids in Patients Aimed at Major Surgery.

Background: Evaluation of improvements by nutrition support to severely ill patients requires sensitive methods to demonstrate activation of protein synthesis in various tissues from groups with a limited number of patients to be statistically efficient. This study examines effects of standard parenteral nutrition (PN) on abdominal muscle transcripts of amino acid (AA) transporters, myosin heavy chains (MHCs), and the insulin-like growth factor 1 and its receptor (IGF-1/IGF-1R) in patients aimed at major surgery.

Methods: Twenty-two randomized patients received steady-state PN (0.

Effects of omeprazole or anti-reflux surgery on lower oesophageal sphincter characteristics and oesophageal acid exposure over 10 years.

Objective: To compare the effect of anti-reflux surgery (ARS) versus proton pump inhibitor therapy on lower oesophageal sphincter (LOS) function and oesophageal acid exposure in patients with chronic gastro-oesophageal reflux disease (GORD) over a decade of follow-up.

Material And Methods: In this randomised, prospective, multicentre study we compared LOS pressure profiles, as well as oesophageal exposure to acid, at baseline and at 1 and 10 years after randomisation to either open ARS (n = 137) or long-term treatment with omeprazole (OME) 20-60 mg daily (n = 108).

Results: Median LOS resting pressure and abdominal length increased significantly and remained elevated in patients operated on with ARS, as opposed to those on OME.

Preoperative overnight parenteral nutrition (TPN) improves skeletal muscle protein metabolism indicated by microarray algorithm analyses in a randomized trial.

Loss of muscle mass is associated with increased risk of morbidity and mortality in hospitalized patients. Uncertainties of treatment efficiency by short-term artificial nutrition remain, specifically improvement of protein balance in skeletal muscles. In this study, algorithmic microarray analysis was applied to map cellular changes related to muscle protein metabolism in human skeletal muscle tissue during provision of overnight preoperative total parenteral nutrition (TPN).

Total or posterior partial fundoplication in the treatment of GERD: results of a randomized trial after 2 decades of follow-up.

Objective And Background: We lack long-term data (>10 years) on the efficacy of antireflux surgery when evaluated within the framework of randomized clinical trials Hereby we report the outcome of a randomized trial comparing open total (I) and a Toupet posterior partial fundoplication (II) performed between 1983 and 1991.

Methods: One hundred and thirty-seven patients with gastroesophageal reflux disease and were enrolled into the study. The mean follow up has now reached 18 years.

Effects by daily long term provision of ghrelin to unselected weight-losing cancer patients: a randomized double-blind study.

Background: The short-term provision of ghrelin to patients with cancer indicates that there may be benefits from long-term provision of ghrelin for the palliative treatment of weight-losing cancer patients. This hypothesis was evaluated in a randomized, double-blind, phase 2 study.

Methods: Weight-losing cancer patients with solid gastrointestinal tumors were randomized to receive either high-dose ghrelin treatment (13 microg/kg daily; n = 17 patients) or low-dose ghrelin treatment (0.

Long-term outcome of microscopic esophagitis in chronic GERD patients treated with esomeprazole or laparoscopic antireflux surgery in the LOTUS trial.

Objectives: Gastroesophageal reflux disease (GERD)-associated changes in esophageal histology have been reported mainly after short-term medical antireflux therapy, and few individual lesions have been examined. We report detailed histological findings from the LOTUS study, at baseline and at 1 and 3 years after laparoscopic antireflux surgery (LARS) or esomeprazole treatment in patients with chronic GERD.

Methods: LOTUS is a long-term, open, parallel-group, multicenter, randomized, controlled trial conducted in 11 European countries that compared LARS (n=248) with esomeprazole 20-40 mg daily (n=266).

Comparison of outcomes twelve years after antireflux surgery or omeprazole maintenance therapy for reflux esophagitis.

Background & Aims: It is important to evaluate the long-term effects of therapies for gastroesophageal reflux disease (GERD). In a 12-year study, we compared the effects of therapy with omeprazole with those of antireflux surgery.

Methods: This open, parallel group study included 310 patients with esophagitis enrolled from outpatient clinics in Nordic countries.

Mechanical consequences of short gastric vessel division at the time of laparoscopic total fundoplication.

Laparoscopic Nissen fundoplication is currently the most commonly practiced antireflux operation. Some adverse consequences of the operation remain in the form of mechanical side effects, labeled postfundoplication complaints, of which dysphagia and gas bloat seem to predominate. Measures have been suggested to counteract some of these and one frequently advocated has been division of the short gastric vessels to create a short-floppy wrap.
