Barrett's esophagus is defined as the endoscopic finding in the distal esophagus of proximal-appearing columnar-lined esophagus of at least 1-cm length that is confirmed by histology.
It is considered a premalignant metaplastic condition that usually involves the distal esophagus.
It is postulated that exposure of the esophageal epithelium to acid damages the lining resulting in chronic esophagitis and its healing involves metaplastic process.
Elevated predicted levels of follicle-stimulating and luteinizing hormones are associated with a lower risk of Barrett’s oesophagus (BE), oesophageal adenocarcinoma (EAC), according to the results of a Mendelian randomization analysis.
A single use trasnasal endoscope, named EG Scan, is safe and highly accurate for detecting Barret’s oesophagus, with the sensitivity and specificity being higher than 90 percent, as compared with conventional esophagogastroduodenoscopy, according to a study.
Factors such as Barret’s oesophagus (BE) length, presence of low-grade dysplasia (LGD) and nodularity increase the risk of progression from nondysplastic (ND)BE or LGD to high-grade dysplasia or oesophageal adenocarcinoma, a study has found.

Antimicrobial resistance has become increasingly dire as the rapid emergence of drug resistance, especially gram-negative pathogens, has outpaced the development of new antibiotics. At a recent virtual symposium, Dr Hsu Li Yang, Vice Dean (Global Health) and Programme Leader (Infectious Diseases), NUS Saw Swee Hock School of Public Health, presented epidemiological data on multidrug-resistant (MDR) gram-negative bacteria (GNB) in Asia, while Dr Tan Thuan Tong, Head and Senior Consultant, Department of Infectious Diseases, Singapore General Hospital (SGH), focused on the role of ceftazidime-avibactam in MDR GNB infections. Dr Andrea Kwa, Assistant Director of Research, Department of Pharmacy, SGH, joined the panel in an interactive fireside chat, to discuss challenges, practical considerations, and solutions in MDR gram-negative infections. This Pfizer-sponsored symposium was chaired by Dr Ng Shin Yi, Head and Senior Consultant of Surgical Intensive Care, SGH.
