The association between two polymorphisms in the TS gene and risk of cancer: A systematic review and pooled analysisemail this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
AbstractThymidylate synthase (TS) is an important enzyme involved in folate metabolism and catalyzes methylation of dUMP to dTMP, which is essential for DNA replication. TSER and TS1494del6, two functionally important and ethnically diverse polymorphisms mapping to its gene region, are the most extensively studied. Considering the potential influence of altering TS activity, it is plausible that TS polymorphisms might play a role in the development of cancer. Although the effects of TS polymorphisms on susceptibility to human cancer have been investigated in many studies, the results remain conflicting rather than conclusi...

The gold standard technique for measuring gastric emptying is scintigraphy using radiolabeled test meals. Recently, a standardized radiolabeled solid meal has been proposed and adopted by many centers. There is still a need for alternative meals, and several such meals with demonstrated radiolabel stability have been evaluated in small numbers of subjects. Updated radiation dosimetry associated with these meals has been calculated for adult males and adult females with normal gastrointestinal transit as well as transit abnormalities.

For many years, gastric emptying (GE) studies were performed using various local protocols and different radiolabeled meals. This lack of standardization and normal values made the test results unreliable and difficult to compare from one site to another. A recent consensus has been published that now provides guidance and standardization on how to perform a radiolabeled solid-meal GE study. It is widely recognized, however, that simple measurement of total GE of a solid meal often does not provide an answer to the etiology of symptoms for a large number of patients who present with functional dyspepsia.

In my last guest editorial on gastrointestinal (GI) nuclear medicine in the Seminars in Nuclear Medicine in October 1995, I pointed out that there are few, if any, other nuclear medicine studies, such as gastric emptying, that are considered a gold standard with which other methods need to be compared. I stressed, however, that there was the need for continued efforts within the nuclear medicine community to prevent tarnishing this gold standard. Since then, we have made significant progress especially in standardizing gastric emptying. Additional progress, however, still needs to be made to prevent new imaging and nonimag...

As pointed out by Dr. Alan Maurer in his guest editorial, it has been more than 15 years since he guest edited another Seminars issue, a two-part review of gastrointestinal (GI) nuclear imaging. A significant portion of the progress that has been made relates to attempted standardization of several of these studies. In particular, cooperative efforts between GI, radiology, and nuclear medicine societies have resulted in standardized methodology for gastric emptying studies. Whereas, half-time of emptying (T1/2) was previously considered the accepted key value or “gold standard,” current thoughts center more on the rete...

We were interested to read the paper by Morris et al demonstrating significant variation in 30-day postoperative mortality following major colorectal cancer surgery in National Health Service hospitals in England.1 While we agree that understanding the underlying causes of this variation will be invaluable to inform best practice, we think that it is necessary to choose a definition of postoperative mortality that provides information relevant to patients as well as clinicians. In cardiothoracic surgery, this issue has been debated for some years, resulting in a measure of ‘operative mortality’ which encompasse...

The treatment of inflammatory bowel disease is becoming more complicated with new medications and new treatment paradigms. Although data are accumulating that the earlier use of immunomodulators and anti-tumor necrosis factor agents are more effective than the standard "step-up" pyramidal treatment algorithm, patients may not be comfortable with this more intensive therapeutic approach. The process of shared decision making engages patients in treatment decisions to optimize the chance that a chosen therapy matches their personal preferences for care. Decision aids are standard shared decision making tools, which are used ...

Pancreatic ductal adenocarcinoma and acinar cells: a matter of differentiation and development?email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
Pancreatic ductal adenocarcinoma (PDAC) has long been considered to arise from pancreatic ducts on the basis of its morphology, the occurrence of dysplasia in putative preneoplastic ductal lesions, and the absence of acinar dysplasia in the pancreas of patients with PDAC. However, evidence gathered through both in vitro studies and—more importantly—genetic mouse models of PDAC shows that ductal-type tumours can arise from acinar cells. These findings raise new important questions related to PDAC pathophysiology and call for in-depth studies of acinar cell differentiation in order to better understand PDAC biolo...

However, the reduced LOS pressure associated with BMI may be mediated by another mechanism or effects of chronic rather than acute elevation of intra-abdominal pressure. (Source: Gut)

Reasons to consider earlier treatment of chronic HBV infectionsemail this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
Introduction Chronic hepatitis B virus (HBV) infection is a serious public health problem, leading to cirrhosis, hepatocellular carcinoma (HCC) and liver failure. In highly endemic areas and among immigrants from these areas, most cases of chronic hepatitis B are due to HBV infection at birth or during the first year of life. Cirrhosis and HCC may occur at any age, but infections early in life are typically asymptomatic for the first few decades. Sharp rises in the incidence of fibrosis, cirrhosis and HCC generally do not appear until after the age of 30, the incidence of HCC showing a sharp rise after the age of 40. Appro...

Bifidobacteria and subsets of dendritic cells: friendly players in immune regulation!email this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
The mammalian gastrointestinal tract harbours a vast number of bacterial residents, recently referred to as the microbiota, which are instrumental in supporting energy metabolism and immune function of the host. A large number of studies have highlighted the fact that certain (pathogenic) micro-organisms can be harmful to the health of their host, while more recently an increasing number of papers have attributed direct beneficial health effects to the gut microbial community. As these bacteria encode 100 times more genes than present in the human genome, the partnership of the host with its microbiota constitute a ‘...

A ZEB1-HDAC pathway enters the epithelial to mesenchymal transition world in pancreatic canceremail this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
Epithelial to mesenchymal transition (EMT) correlates with high-grade malignancy including the competence to form metastases. In addition, EMT has recently been linked to cellular self-renewal programmes of cancer stem cells and apoptosis/anoikis resistance, which are all features of therapeutic resistance. The EMT programme is driven by several transcription factors (TFs), such as the transcriptional regulators SNAIL, SLUG, ZEB1 and ZEB2 and the basic helix–loop–helix factors E47 and TWIST. These proteins target and repress the CDH1 gene, which encodes for E-cadherin, an important caretaker of the epithelial s...

Luminal GIH1N1 influenza vaccination and IBD The global pandemic of novel influenza A (H1N1) affected 70 countries in 2009. There was particular concern for infection in immunocompromised patients, including those with IBD. The 2009 H1N1 influenza vaccine produced seroprotection rates of >85% in the general population but there are no data on the immunogenicity of the vaccine in patients with IBD. In this issue of Gut, Cullen et al report their observational prospective open-label study which examined the immunogenicity of the 2009 H1N1 influenza vaccine in IBD patients. Patients with IBD vaccinated with the 2009 H1N1 i...

Transgenic overexpression of intraislet ghrelin does not affect insulin secretion or glucose metabolism in vivoemail this articleEmail this article to a colleague. save this article to My ClippingsSave this article to My Clippings. discuss this articleDiscuss or comment on this article.
Whereas ghrelin is produced primarily in the stomach, a small amount of it is produced in pancreatic islets. Although exogenous administration of ghrelin suppresses insulin secretion in vitro or in vivo, the role of intraislet ghrelin in the regulation of insulin secretion in vivo remains unclear. To understand the physiological role of intraislet ghrelin in insulin secretion and glucose metabolism, we developed a transgenic (Tg) mouse model, rat insulin II promoter ghrelin-internal ribosomal entry site-ghrelin O-acyl transferase (RIP-GG) Tg mice, in which mouse ghrelin cDNA and ghrelin O-acyltransferase are overexpressed ...
