OBJECTIVES: Emergency departments (ED) continue to be overburdened, leading to crowding and elevated risk of negative clinical outcomes. Extending clinical services to paramedics may support efforts to improve ED burdens by promoting health care access and capacity during times of patient crisis. The objective of this study was to identify the clinical course and most responsible diagnosis of patients transported by paramedic services to local EDs to then evaluate impact of various augmented 9-1-1/paramedic clinical service models on the need for additional ED services...

Barrett's oesophagus is a pre-malignant condition associated with the development of oesophageal adenocarcinoma. Currently white light endoscopy and biopsy is the mainstay diagnostic tool. Yet this approach is troubled by issues related to cumbersome biopsy sampling, biopsy sampling errors and cost. Therefore in order to overcome such adversity, there needs to be evolutionary advancement in terms of diagnosis, which should address these concerns and ideally enhance risk stratification in order to provide timely management in real time...

The use of contrast media in computed tomography (CT) and magnetic resonance imaging (MRI) is increasing in horses. These contrast-enhanced imaging techniques provide improved tissue delineation and evaluation thereby expanding diagnostic capabilities. While generally considered safe, not all contrast media exhibit the same safety profiles. The safety of contrast media use and descriptions of adverse events occurring in horses are sparsely reported. This review summarises the reported evidence of contrast media use and adverse events that occur in horses, with added contribution from other veterinary species and human studies for comparison...

PURPOSE OF REVIEW: The incidence of esophageal adenocarcinoma is on the rise despite widespread appreciation that the precursor lesion is Barrett's esophagus. Studies have shown that some patients known to have Barrett's esophagus develop cancer despite their enrollment in conventional endoscopic surveillance programs. This highlights the need for advanced endoscopic imaging to help identify early neoplasia and prevent its progression to esophageal cancer. Recently, a wide-field, second-generation optical coherence tomography endoscopic platform called volumetric laser endomicroscopy (VLE) was cleared by the Food and Drug Administration and made commercially available for advanced imaging in Barrett's esophagus...

Objectives: To test miR-223 upregulation during gastric (intestinal-type) and Barrett esophageal carcinogenesis. Methods: miR-223 expression was assessed by quantitative reverse transcription polymerase chain reaction in a series of 280 gastroesophageal biopsy samples representative of the whole spectrum of phenotypic changes involved in both carcinogenetic cascades. The results were further validated by in situ hybridization on multiple tissue specimens obtained from six surgically treated gastroesophageal adenocarcinomas...

BACKGROUND: Although there are effective psychological treatments for unipolar major depression in adolescents, whether or not one or more of the available therapies maintain reduced depressive symptoms 1 year after the end of treatment is not known. This is a non-trivial issue because maintaining lowered depressive symptoms below a clinical threshold level reduces the risk for diagnostic relapse into the adult years. OBJECTIVE: To determine whether or not either of two specialist psychological treatments, cognitive-behavioural therapy (CBT) or short-term psychoanalytic psychotherapy (STPP), is more effective than a reference brief psychosocial intervention (BPI) in maintaining reduction of depression symptoms in the year after treatment...

BACKGROUND/AIMS: Mild cognitive impairment (MCI) is present in up to 34% of patients with early-stage Parkinson disease (PD); however, it is difficult to detect subtle impairment without objective cognitive testing. METHODS: Data were obtained from the Parkinson Progression Marker Initiative. All 341 participants were administered the Montreal Cognitive Assessment (MoCA) and a brief neuropsychological battery. Participants were classified as PD-MCI if MoCA was <26 or if they scored ≥1 standard deviation below the normative mean in 2 or more domains, based upon established criteria...

Gastroesophageal reflux disease (GERD) has a large economic burden with important complications that include esophagitis, Barrett's esophagus, and adenocarcinoma. Despite endoscopy, validated patient questionnaires, and traditional ambulatory pH monitoring, the diagnosis of GERD continues to be challenging. Areas covered: This review will explore the difficulties in diagnosing GERD with a focus on new developments, ranging from basic fundamental changes (histology and immunohistochemistry) to direct patient care (narrow-band imaging, impedance, and response to anti-reflux surgery)...

Barrett's oesophagus is a condition which predisposes towards development of oesophageal adenocarcinoma, a highly lethal tumour which has been increasing in incidence in the Western world over the past three decades. There have been tremendous advances in the field of Barrett's oesophagus, not only in diagnostic modalities, but also in therapeutic strategies available to treat this premalignant disease. In this review, we discuss the past, present and future of Barrett's oesophagus. We describe the historical and new evolving diagnostic criteria of Barrett's oesophagus, while also comparing and contrasting the British Society of Gastroenterology guidelines, American College of Gastroenterology guidelines and International Benign Barrett's and CAncer Taskforce (BOBCAT) for Barrett's oesophagus...

Hepatocyte antigen or hepatocyte paraffin 1 (Hep Par 1) is widely used as a diagnostic immunomarker for hepatocellular carcinoma. It has also been identified as a rate-limiting enzyme of the urea cycle, carbamoyl phosphate synthetase 1. Hep Par 1 has been detected in non-neoplastic small intestinal epithelium, but its expression in Barrett esophagus and its related neoplasia has not been well investigated. We immunohistochemically evaluated expression of Hep Par 1 on 75 cases of Barrett esophagus (25 cases without dysplasia, 16 cases with low-grade dysplasia, 25 cases with high-grade dysplasia, and 9 cases with intramucosal adenocarcinoma) on endoscopic biopsies and endoscopic mucosal resections...

BACKGROUND AND AIMS: Angiogenesis is associated with neoplastic progression of Barrett's esophagus (BE). Volumetric optical coherence tomography angiography (OCTA) visualizes subsurface microvasculature without exogenous contrast agents. We investigated the association of OCTA microvascular features with low-grade dysplasia (LGD) and high-grade dysplasia (HGD). METHODS: Fifty-two patients undergoing BE surveillance or endoscopic eradication therapies for dysplasia were imaged using volumetric OCTA and corresponding histologic diagnoses wre obtained to yield 97 data sets (nondysplastic BE [NDBE], 74; LGD, 10; HGD, 13)...

Patients with Barrett's esophagus (BO) are at increased risk of developing esophageal adenocarcinoma (EAC). Most Barrett's patients, however, do not develop EAC, and there is a need for markers that can identify those most at risk. This study aimed to see if a metabolic signature associated with the development of EAC existed. For this, tissue extracts from patients with EAC, BO, and normal esophagus were analyzed using (1)H nuclear magnetic resonance. Where possible, adjacent histologically normal tissues were sampled in those with EAC and BO...

PURPOSE OF REVIEW: Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a congenital aerodigestive anomaly with high survival rates after surgical repair. Care should now be focused on prevention of long-term complications using appropriate surveillance techniques. RECENT FINDINGS: The incidence of gastroesophageal reflux disease (GERD) is high in patients with EA/TEF. Consequences of untreated GERD include esophagitis, strictures, and Barrett esophagus. Subjective symptoms are an unreliable indicator of presence or severity of GERD, and therefore, diagnostic testing is needed to assess esophageal heath and monitor the effectiveness of anti-reflux treatment...
