BACKGROUND: Barrett's esophagus metaplasia is the key precursor lesion of esophageal adenocarcinoma. The aim of this study was to find a subset of markers that may allow the identification of patients at risk for esophageal adenocarcinoma, and to determine genes differentially expressed in esophageal squamous cell carcinoma. METHODS: Laser capture microdissection technique was applied to procure cells from defined regions. Genome-wide RNA profiling was performed on esophageal adenocarcinoma (n = 21), Barrett's esophagus (n = 20), esophageal squamous carcinoma (n = 9) and healthy esophageal biopsies (n = 18) using the Affymetrix Human Genome U133plus 2...

A 71-year-old male patient with a long-segment (C10M12) Barrett's esophagus harboring multifocal high-grade dysplasia was referred to our clinic. After a multidisciplinary team conference and the patient's informed consent, an endoscopic submucosal dissection (ESD) was performed with resection of 4/5 of the esophageal circumference along 12 cm, without any complications during or immediately after the procedure. In the day after the ESD, the patient presented suddenly with dyspnea and subcutaneous emphysema in the neck and chest...

Lameness and polyserositis in pigs caused by Mycoplasma hyorhinis are generally treated with antibiotics and may require multiple doses. The costs of these antibiotics combined with economic losses from culling and reduced feed conversion due to lameness are hardships to the swine producer. In this study we have demonstrated efficacy of an inactivated M. hyorhinis vaccine administered to three-week old caesarian-derived colostrum-deprived piglets. Three doses of vaccine (high, medium, and low) were evaluated and compared to a placebo control...

BACKGROUND: A safe, effective, and rapidly scalable vaccine against Zika virus infection is needed. We developed a purified formalin-inactivated Zika virus vaccine (ZPIV) candidate that showed protection in mice and non-human primates against viraemia after Zika virus challenge. Here we present the preliminary results in human beings. METHODS: We did three phase 1, placebo-controlled, double-blind trials of ZPIV with aluminium hydroxide adjuvant. In all three studies, healthy adults were randomly assigned by a computer-generated list to receive 5 μg ZPIV or saline placebo, in a ratio of 4:1 at Walter Reed Army Institute of Research, Silver Spring, MD, USA, or of 5:1 at Saint Louis University, Saint Louis, MO, USA, and Beth Israel Deaconess Medical Center, Boston, MA, USA...

Dysregulation of microRNAs (miRNAs) has been linked to virulence factors of Helicobacter pylori (H. pylori). The role of H. pylori in esophageal disease has not been clearly defined. We previously reported that H. pylori-esophageal colonization promotes the incidence of Barrett's esophagus and esophageal adenocarcinoma in vivo. Here, we studied the direct effects of H. pylori on the transformation of esophageal epithelial cells, with particular focus on whether H. pylori exerts its effects by modulating miRNAs and their downstream target genes...

Ovarian cancer patients with germline or somatic pathogenic variants benefit from treatment with PARP inhibitors. Tumour BRCA1/2 testing is more challenging than germline testing as the majority of samples are formalin fixed paraffin embedded (FFPE), the tumour genome is complex and the allelic fraction of somatic variants can be low. We collaborated with 10 laboratories testing BRCA1/2 in tumours to compare different approaches to identify clinically important variants within FFPE tumour DNA samples. This was not a proficiency study but an inter-laboratory comparison to identify common issues...

Background and aims: Although genome-wide association studies (GWAS) in inflammatory bowel disease (IBD) have identified a large number of common disease susceptibility alleles for both Crohn's disease (CD) and ulcerative colitis (UC), a substantial fraction of IBD heritability remains unexplained, suggesting that rare coding genetic variants may also have a role in pathogenesis. We used high-throughput sequencing in families with multiple cases of IBD, followed by genotyping of cases and controls, to investigate whether rare protein altering genetic variants are associated with susceptibility to IBD...

The current standard of treating early Barrett's neoplasia is resection of visible lesions using endoscopic mucosal resection (EMR) followed by ablative therapy to the Barrett's segment. There is increasing evidence to support the use of endoscopic submucosal dissection (ESD) where en-bloc resection and lower recurrence rates may be achieved. However, ESD is associated with deep submucosal dissection when compared to EMR. This may increase the risk of complications including stricture formation with subsequent radiofrequency ablation (RFA) therapy...

Across many unrelated lineages of plants and animals, Y chromosomes show a recurrent pattern of gene degeneration and loss, but the relative importance of inefficient selection, adaptive gene silencing, and neutral genetic drift in causing degeneration remain poorly understood. Here, we use next-generation genome and transcriptome sequencing to investigate patterns of ongoing Y chromosome degeneration in two annual plant species of Rumex (Polygonaceae) differing in their degree of degeneration and sex chromosome heteromorphism...

Changes in the field of pathology and resident education necessitate ongoing evaluation of residency training. Evolutionary change is particularly important for surgical pathology rotations, which form the core of anatomic pathology training programs. In the past, we organized this rotation based on subjective insight. When faced with the recent need to restructure the rotation, we strove for a more evidence-based process. Our approach involved 2 primary sources of data. We quantified the number of cases and blocks submitted per case type to estimate workload and surveyed residents about the time required to gross specimens in all organ systems...

The histological commitment of the lower oesophageal mucosa largely depends on a complex molecular landscape. After extended inflammatory insult due to gastroesophageal reflux disease, squamous oesophageal mucosa may differentiate into columnar metaplastic mucosa. In this setting, the presence of intestinal metaplasia is considered the starting point of Barrett's carcinogenetic cascade. Aside from secondary prevention strategies for Barrett's mucosa (BM) patients, there are multiple endoscopic ablative therapies available for BM eradication and for the replacement of metaplastic epithelia with a neosquamous mucosa...

INTRODUCTION: Barrett's Esophagus (BE) represents an early stage in carcinogenesis leading to esophageal adenocarcinoma (EAC). Considerable evidence supports a major role for chronic inflammation and diverse chemokine pathways in the development of BE and EAC. METHODS: Here we utilized a IL-1b transgenic mouse model of BE and EAC and human patient imaging to analyse the importance of CXCR4 expressing cells during esophageal carcinogenesis. RESULTS: IL-1b overexpression induces chronic esophageal inflammation and recapitulates the progression to BE and EAC...
