Impact of the Delta variant and vaccination on SARS-CoV-2 transmission remains unclear. In Singapore, quarantine all close contacts, including entry exit PCR testing, provided opportunity to determine risk infection by compared other variants, vaccine efficacy against acquisition, symptomatic or severe COVID-19, factors associated with acquisition disease.

Ethionamide (ETH) is part of the drug arsenal available to treat multi-drug resistant tuberculosis. The current paradigm this pro-drug activation involves mycobacterial enzyme EthA and transcriptional repressor, EthR. However, several lines evidence suggest involvement additional players. ethA/R locus was deleted in Mycobacterium bovis BCG three tuberculosis (MTB) strains. While complete resistance ETH observed with KO, susceptibility dose-dependent killing were retained KO MTB mutants,...

Falls among older adults are a significant health problem globally. Studies of multicomponent fall prevention programs in randomized controlled trials demonstrate effectiveness reducing falls; however, the translation research into community remains challenging. Although there is an increasing interest to understand factors contributing implementation barriers, dynamic relationships between less well examined. Furthermore, evidence on barriers from Asia lacking as most these studies...

The spread of Carbapenemase-producing Organisms (CPO) remains a major threat globally. Within clinical settings, the existing method determining gene load involves traditional culture to determine bacterial and polymerase-chain-reaction-based Xpert Carba-R Assay carbapenemase type. However, there is need for fast accurate quantifying CPO colonisation study risk persistent carriage.

Falls and fall-related injuries among older adults in Singapore are a serious health problem that require early intervention. In previous research, exercise interventions have been effective improving functional outcomes reducing falls for broad group of adults. However, results from multi-domain, multi-component prevention programs high fall risk the community remain equivocal. One reason these is there significant heterogeneity factors amongst which makes tailoring multicomponent complex....
