Analytical sensitivity and clinical performance of a triplex RT-qPCR assay using CDC N1, N2, and RP targets for SARS-CoV-2 diagnosis

The nCoV19 CDC includes two targets for detecting SARS-CoV-2 and an RNaseP (RP) and an RNA extraction quality control. Several RT-qPCR kits are available for SARS and some have emergency use from the US Food and Drug Administration. Only one set of DNA is required for each sample to be tested.

SARS-CoV-2 screening of asymptomatic women admitted for delivery must be performed with a combination of microbiological techniques: an observational study

Authors: 9 women were positive for SARS-CoV-2 in nasopharyngeal samples and 13 presented positive specific antibodies of the coronavirus. Vaginal delivery occurred in 94% of the cases and only 6% underwent a cesarean section, always for obstetric reasons. No fetal transmission was observed and maternal and neonatal prognosis was excellent.

A study comparing an endoscopy nurse and an endoscopy physician in capsule endoscopy interpretation

Reviewing wireless capsule endoscopy recordings by a physician is time-consuming and laborious. The study evaluated the efficacy of a nurse in interpreting WCE recordings. Nurse's mean capsule reading time was significantly longer for the nurse compared with the gastroenterologist.

Systematic review with meta-analysis: Chromoendoscopy versus white light endoscopy in detection of dysplasia in patients with inflammatory bowel disease

When magnification was added to CE, the detection rate of patients with dysplasia and dysplastic lesions improved. It is thus necessary to use CE in the surveillance of Dysplasia in patients with IBD in clinical practice, authors say.

[Comparative of gastrointestinal mesenchymal tumors of CT virtual endoscopy and pathology]

Objective: To observe the lower gastrointestinal mesenchymal tumors CT virtual endoscopy and pathology. Methods: Select 80 patients suspected colon gastroenterology treat in the hospital gastroenterologist department.

Reproducibility of wireless capsule endoscopy in the investigation of chronic obscure gastrointestinal bleeding

Capsule endoscopy is a valuable tool in the diagnostic evaluation of obscure gastrointestinal bleeding. A potential small intestinal bleeding source was found in 60% of the patients when all the studies were combined. Some patients did not have a source of bleeding in the small intestine.

Systematic review and meta-analysis of randomized controlled trials of Simethicone for gastrointestinal endoscopic visibility

Simethicone is used to increase the small bowel visualization quality (SBVQ), completion rate, gastric transit time, small bowel transit time and diagnostic yield. It decreases air bubbles in the colonic lumen, but does not improve bowel preparation.

Embolization for non-variceal upper gastrointestinal tract haemorrhage: a systematic review

Aim: To assess the endovascular treatment of non-variceal upper gastrointestinal hemorrhage. The technical and clinical success of embolization ranged from 52-100% and 44-100%.
