Echocardiography is the primary diagnostic modality for congenital heart disease patients. The written report is used to communicate with the care team and organization is often divided into the body with detailed findings and the conclusions with important findings summarized. Strategies to increase workflow efficiency include batch writing of reports after performance of multiple echocardiograms and the use of report templates which may contribute to discrepancies within report leading to potential downstream medical errors...

Articular cartilage is a critical joint tissue and its evaluation remains a diagnostic challenge in horses. Coupled with a poor capacity for healing, early degenerative changes in articular cartilage are difficult to characterise using routine diagnostic imaging evaluations. Computed tomography (CT) and magnetic resonance imaging (MRI) both provide volumetric joint assessment and highlight morphologic and quantitative properties of articular cartilage, improving assessment of this essential tissue. While the use of CT and MRI for joint evaluation is not new, there still remains a shortage of literature and scientific studies on the ability of these methods to evaluate articular cartilage in the horse...

Nuclear activation of Wnt/β-catenin signaling is required for cell proliferation in inflammation and cancer. Studies from our group indicate that β-catenin activation in colitis and colorectal cancer (CRC) correlates with increased nuclear levels of β-catenin phosphorylated at serine 552 (pβ-Cat552). Biochemical analysis of nuclear extracts from cancer biopsies revealed the existence of low molecular weight (LMW) pβ-Cat552, increased to the exclusion of full size (FS) forms of β-catenin. LMW β-catenin lacks both termini, leaving residues in the armadillo repeat intact...

PurposeGiven the rapid pace of discovery in rare disease genomics, it is likely that improvements in diagnostic yield can be made by systematically reanalyzing previously generated genomic sequence data in light of new knowledge.MethodsWe tested this hypothesis in the United Kingdom-wide Deciphering Developmental Disorders study, where in 2014 we reported a diagnostic yield of 27% through whole-exome sequencing of 1,133 children with severe developmental disorders and their parents. We reanalyzed existing data using improved variant calling methodologies, novel variant detection algorithms, updated variant annotation, evidence-based filtering strategies, and newly discovered disease-associated genes...

AIMS: Interobserver agreement for dysplasia in Barrett's oesophagus (BO) is low and guidelines advise expert review of dysplastic cases. We assessed the added value of p53 immunohistochemistry (IHC) on the homogeneity within a group of dedicated gastro-intestinal (GI) pathologists. METHODS AND RESULTS: Sixty single hematoxylin & eosin (HE) slide referral BO cases (20 low-grade dysplasia (LGD); 20 high-grade dysplasia (HGD) and 20 non-dysplastic BO (NDBO) reference cases) were digitalised and independently assessed twice in a random order by 10 dedicated GI pathologists...

Human fecal contamination of water is a public health risk. However, inadequate testing solutions frustrate timely, actionable monitoring. Bacterial culture-based methods are simple but typically cannot distinguish fecal host source. PCR assays can identify host sources but require expertise and infrastructure. To bridge this gap we have developed a field-ready nucleic acid diagnostic platform and rapid sample preparation methods that enable on-site identification of human fecal contamination within 80 min of sampling...

Current understanding of the mutation spectrum of relapsed/refractory (RR) tumors is limited. We performed whole exome sequencing (WES) on 47 diffuse large B cell lymphoma (DLBCL) tumors that persisted after R-CHOP treatment, 8 matched to primary biopsies. We compared genomic alterations from the RR cohort against two treatment-naïve DLBCL cohorts (n=112). While the overall number and types of mutations did not differ significantly, we identified frequency changes in DLBCL driver genes. The overall frequency of MYD88 mutant samples increased (12% to 19%), but we noted a decrease in p...

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...

BACKGROUND: Early signs of canine transitional cell carcinoma (TCC) are frequently assumed to be caused by other lower urinary tract diseases (LUTD) such as urinary tract infections, resulting in late diagnosis of TCC which could be fatal. The development of a non-invasive clinical test for TCC could dramatically reduce mortality. To determine whether microRNAs (miRNAs) can be used as non-invasive diagnostic biomarkers, we assessed miRNA expression in blood and/or urine from dogs with clinically normal bladders (n = 28), LUTD (n = 25), and TCC (n = 17)...

We describe a family who presented with several scattered, vascular, cutaneous lesions and was found to have a novel mutation in RASA1, diagnostic of capillary malformation-arteriovenous malformation syndrome. Our patient was initially given a presumptive clinical diagnosis of hereditary hemorrhagic telangiectasia. Capillary malformation-arteriovenous malformation syndrome shares several features with hereditary hemorrhagic telangiectasia and hereditary benign telangiectasia, but it can be distinguished clinically according to its morphologic appearance and distribution of cutaneous vascular lesions, the presence of internal fast-flow lesions, and genetic analysis...

The prevalence of gastroesophageal reflux disease as well as the incidence of Barrett's esophagus (BE) has increased in the Western world over the last decades. The chronic reflux of gastric secretions injuries the esophageal mucosa and triggers cellular and molecular changes inducing the transformation of the normal squamous mucosa into columnar metaplastic epithelium. BE is a premalignant condition that can progress to low-grade dysplasia, high-grade dysplasia and ultimately esophageal adenocarcinoma. An early diagnosis of dysplastic changes and the adoption of appropriate therapeutic approaches are essential to improve patient outcomes and survival...

Barrett's esophagus (BE) is associated with an increased risk of developing esophageal adenocarcinoma. Despite the low absolute risk of neoplastic progression of BE, probability increases with the diagnosis of dysplasia. For this reason, BE patients undergo an endoscopy-based surveillance that is, however, burdensome for patients, subject to inter-observer subjectivity, and expensive for national health systems. Thus, less invasive and low-cost diagnostic tools are needed. This study is aimed at finding a simple and reliable method to detect the circulating cell-free DNA (cfDNA) in BE patients as evidence of the molecular instability that accompanies BE carcinogenesis...

BACKGROUND: Brain homeostasis deteriorates in sepsis, giving rise to a mostly reversible sepsis-associated encephalopathy (SAE). Some survivors experience chronic cognitive dysfunction thought to be caused by permanent brain injury. In this study, we investigated neuroaxonal pathology in sepsis. METHODS: We conducted a longitudinal, prospective translational study involving (1) experimental sepsis in an animal model; (2) postmortem studies of brain from patients with sepsis; and (3) a prospective, longitudinal human sepsis cohort study at university laboratory and intensive care units (ICUs)...
