Wide-area transepithelial sampling for dysplasia detection in Barrett's esophagus: a systematic review and meta-analysis.

Background And Aims: Seattle protocol forceps biopsy sampling (FB) is currently recommended for surveillance in Barrett's esophagus (BE) but limited by sampling error and lack of compliance. Wide-area transepithelial sampling with 3-dimensional analysis (WATS3D; CDx Diagnostics, Suffern, NY, USA) is reported to increase BE dysplasia detection. We assessed the incremental yield and clinical significance of WATS3D for dysplasia detection over FB in a systematic review and meta-analysis.

Novel Screening Alternatives for Barrett Esophagus.

Barrett esophagus (BE) is the only known premalignant precursor to esophageal adenocarcinoma (EAC), a deadly malignancy that carries a dismal prognosis. Guidelines currently recommend screening for BE only in high-risk populations, such as patients with chronic gastroesophageal reflux disease (GERD) and 1 or more additional risk factors. A GERD-centered approach to BE screening likely leads to a large number of missed EAC cases, as the true population prevalence of BE is thought to be much higher than current estimates.

Role of MIL-53(Fe)/hydrated-dehydrated MOF catalyst for electrochemical hydrogen evolution reaction (HER) in alkaline medium and photocatalysis.

The role of breathing behavior in hydrated and dehydrated forms of MIL-53(Fe) is investigated here. The material can be used as an efficient electrocatalyst and photocatalyst for a hydrogen evolution reaction (HER) in an alkaline medium and the same was further tested for the degradation of organic pollutants. The as-synthesized MIL-53(Fe)/hydrated and dehydrated forms were characterized by different analytical techniques to study their structure, morphology, surface analysis, thermal, physical and chemical properties.
