A pancreatic fistula is defined as the leakage of pancreatic fluid into another organ or compartment because of pancreatic duct disruption or pseudocyst formation. It is most often seen in middle-aged men between 40 and 50, particularly in patients who have a history of chronic alcoholism and pancreatitis. The tract may fistulae into the pleura, creating a pancreaticopleural fistula, an exceedingly rare condition presenting as a recurrent pleural effusion and extremely high amylase levels, a key distinguishing factor in diagnosis.

Since the Asian Pacific Association for the Study of the Liver (APASL) published guidelines on non-cirrhotic portal fibrosis/idiopathic portal hypertension in 2007, there has been a surge in new information, especially with the introduction of the term porto-sinusoidal vascular disorder (PSVD). Non-cirrhotic intra-hepatic causes of portal hypertension include disorders with a clearly identifiable etiology, such as schistosomiasis, as well as disorders with an unclear etiology such as non-cirrhotic portal fibrosis (NCPF), also termed idiopathic portal hypertension (IPH). This entity is being increasingly recognized as being associated with systemic disease and drug therapy, especially cancer therapy.

Biosensors for autoimmune diseases.

Clin Chim Acta

January 2025

Biosensor Sciences and Technologies Research Center, Ardabil University of Medical Sciences, Ardabil, Iran. Electronic address:

Diagnosis of autoimmune diseases (ADs) is usually based on symptoms and laboratory tests that measure the occurrence of serological and genetic biomarkers such as peptides, autoantibodies, and complement proteins. Early detection of AD is essential to reduce the severity of symptoms and organ damage as a result of progressive disease. Biosensors are tools that convert biochemical signals produced by molecular elements into optical, electrical, and other physical signals for analysis.

An observational study of the causes of an isolated elevated alkaline phosphatase level of unclear etiology.

Am J Med Sci

October 2024

Digestive Disease Research Center, Medical University of South Carolina, 96 Jonathan Lucas Street, Suite 908, Charleston, SC 29425, USA. Electronic address:

Article Synopsis
  • Serum alkaline phosphatase (ALP) is frequently tested in patients, but it lacks specific diagnostic value since it can originate from multiple tissues; this study explores causes of isolated elevated ALP levels without a clear reason.
  • A retrospective study at the Medical University of South Carolina looked at 260 adults with unexplained elevated ALP results and found that 57% of cases were linked to underlying malignancies, particularly related to the liver and bones.
  • The study highlights the importance of recognizing an isolated elevated ALP as potentially indicative of serious conditions, especially metastatic cancer, rather than just primary liver issues.

Background: Multitarget stool DNA (MT-sDNA) tests (here, Cologuard®) are currently used in average-risk patients as a primary method of screening for colorectal cancer. However, MT-sDNA testing has also been used in patients who previously underwent colonoscopy who wish to avoid repeat colonoscopy. Here, in a large primary care practice setting, our aim was to evaluate the diagnostic performance of MT-sDNA testing in patients with a previously normal colonoscopy.

Gastric cancer's (GC) cause is unknown, but its complexity indicates that, in addition to environmental factors, it may have genetic origins. Scientists are studying single-nucleotide polymorphisms (SNPs) in the antisense noncoding RNA in the INK4 locus (ANRIL) gene, which encodes a long noncoding RNA molecule. They found a link between the ANRIL gene product and some polymorphisms and GC, suggesting genetic changes may lead to precancerous conditions.

Background: Drug-induced liver injury (DILI) is a major concern for oncology drugs in clinical practice and under development. Monitoring cancer patients for hepatotoxicity is challenging as these patients may have abnormal liver tests pre-treatment or on-study for many reasons including liver injury due to past oncology treatments, hepatic metastases, medical co-morbidities such as heart failure, and concomitant medications. At present, there are no regulatory guidelines or position papers that systematically address best practices pertaining to DILI detection, assessment and management in oncology patients.

Department of Molecular Physiology and Biophysics, Vanderbilt University, Nashville, TN, USA; Vanderbilt Digestive Disease Research Center, Vanderbilt University Medical Center, Nashville, TN, USA; Vanderbilt Diabetes Research Center, Vanderbilt University, Nashville, TN, USA. Electronic address:

A key organismal response to overnutrition involves the development of new adipocytes through the process of adipogenesis. Preadipocytes sense changes in the systemic nutrient status and metabolites can directly modulate adipogenesis. We previously identified a role of de novo nucleotide biosynthesis in adipogenesis induction, whereby inhibition of nucleotide biosynthesis suppresses the expression of the transcriptional regulators PPARγ and C/EBPα.
