INTRODUCTION: Code status discussions form an important part of advance care planning (ACP) as it enables physicians to respect the patient's wishes for end-of-life care. However, in some cases, code status discussions can be challenging causing the physician to go against the patient's wishes and the code of medical ethics. This is especially true in an emergency setting. In this paper, we will discuss three cases of advanced cancer patients, where code status discussions posed challenges to healthcare providers...

REVIEW
Rupert Langer, Karen Becker
Neoadjuvant therapy has been successfully introduced in the treatment of locally advanced gastrointestinal malignancies, particularly esophageal, gastric, and rectal cancers. The effects of preoperative chemo- or radiochemotherapy can be determined by histopathological investigation of the resection specimen following this treatment. Frequent histological findings after neoadjuvant therapy include various amounts of residual tumor, inflammation, resorptive changes with infiltrates of foamy histiocytes, foreign body reactions, and scarry fibrosis...

AIMS/HYPOTHESIS: Roux-en-Y gastric bypass (RYGB) surgery is characterised by glycaemic variability. Prospective studies of glucose metabolism in pregnancy after RYGB are not available, therefore this study aimed to evaluate physiological alterations in glucose metabolism in pregnancy following RYGB. METHODS: Sixty-three pregnant women (25 who underwent RYGB, 19 non-operated obese control women and 19 normal weight control women) were included. Frequently sampled 3 h OGTTs and 1 h IVGTTs were performed between 24 and 28 weeks of gestation and, in a subgroup, were repeated at 3-6 months after delivery...

BACKGROUND: Visceral artery aneurysms at the origin of the gastric and gastroepiploic artery are uncommon. Raptured visceral aneurysms cause high mortality and require urgent and adequate intervention and treatment. PRESENTATION OF CASE: A 65-year-old woman was transferred to the emergency department with sudden abdominal and back pain. Radiographically, we diagnosed intra-abdominal bleeding due to a ruptured aneurysm of the right gastric artery. Although her vital signs were relatively stable, transcatheter arterial embolization (TAE) could not be performed due to thrombotic occlusion of her abdominal aorta, and bilateral axillary arteries...

We, along with others, have shown previously that P21-activated kinase 1 (Pak1) plays a pivotal role in gastric cancer progression and metastasis. However, whether Pak1 controls gastric cancer metastasis by regulating microRNAs (miRNAs) has never been explored. Here, we report a novel mechanism of Pak1 in tumor metastasis. A detailed examination revealed that Pak1 interacts with and phosphorylates the serine 62 residue of ATF2 and then blocks its translocation into the nucleus. We also confirmed that ATF2 binds to the promoter of miR-132 and tightly regulates its transcription, thus explaining the regulatory mechanism of miR-132 by Pak1...

Long noncoding RNA (lncRNA) has been implicated in cancer, but little is known about the role of lncRNAs as regulators of tumor metastasis. In the present study, we demonstrate that lncRNA TRERNA1 acts like an enhancer of SNAI1 to promote cell invasion and migration and to contribute to metastasis of gastric cancer (GC). TRERNA1 is significantly unregulated in GCs and GC cell lines. Increased TRERNA1 is positively correlated with lymph node metastasis of GCs. RNA immunoprecipitation (RIP) and chromatin immunoprecipitation (ChIP) assays revealed that TRERNA1 functions as a scaffold to recruit EZH2 to epigenetically silence epithelial-mesenchymal transition marker CDH1 by H3K27me3 of its promoter region...

Synthetic oligodeoxynucleotides containing unmethylated CpG motifs (CpG ODNs) stimulate immune cells via Toll-like receptor 9 (TLR9). Because oligodeoxynucleotides (ODNs) are susceptible to gastric degradation, clinical trials designed to evaluate their therapeutic utility have relied solely on parenteral routes of administration. A strategy to improve the activity of orally delivered ODNs by reducing their susceptibility to gastrointestinal (GI) digestion via encapsulation in calcium carbonate nanoparticles (ODNcaps) was recently described...

To examine the potential of chitosan-based agents for submucosal injection in endoscopic techniques, a chitosan derivative was prepared with lactose moieties linked to the amino groups of its glucosamine units (CH-LA). After dissolving CH-LA in neutral pH solutions, including physiological saline (CH-LA-S), its response to different concentrations of anionic glycosaminoglycans and proteins in the surrounding environment was examined. The CH-LA-S form changed in the presence of sulfated glycosaminoglycans (heparin, chondroitin sulfate, and mucin) and protein (fibrinogen)...

BACKGROUND: Alcohol consumption has been found to be associated with gastric ulcers, including gastric mucosal lesions. Salusin-α and salusin-β are bioactive peptides having 28 and 20 amino acids, respectively. Salusin-α and salusin-β immunoreactivity has been detected in the stomach and in the intestines. It has been reported that the salusins regulate the cytokine levels and decrease the infarct area in the heart tissue after ischemia. In this study, we investigated the effects of the salusins in the gastric injury formed with ethanol...

OBJECTIVE: Synoptic reporting (SR) is one solution to improve the quality of operative reports. However, SR has not been investigated in bariatric surgery despite an identified need by bariatric surgeons. SR for RYGB was developed using quality indicators (QIs) established by a national Delphi process. The objective of this study is to assess the completeness, accuracy, reliability, and efficiency of synoptic versus narrative operative reports (NR) in Roux-en-Y gastric bypass (RYGB). METHODS: A NR and SR were completed on 104 consecutive RYGBs...

The ability to reliably and safely communicate chronically with small diameter (100-300 µm) autonomic nerves could have a significant impact in fundamental biomedical research and clinical applications. However, this ability has remained elusive with existing neural interface technologies. Here we show a new chronic nerve interface using highly flexible materials with axon-like dimensions. The interface was implemented with carbon nanotube (CNT) yarn electrodes to chronically record neural activity from two separate autonomic nerves: the glossopharyngeal and vagus nerves...
