Determinants of residential greenness and its association with prostate cancer risk: A case-control study in Singapore.

Background: Exposure to greenness has been shown to be beneficial to health, but few studies have examined the association between residential greenness and prostate cancer (PCa) risk. Our main objectives were to identify the determinants of residential greenness, and to investigate if residential greenness was associated with PCa risk in Singapore.

Methods: The hospital-based case-control study was conducted between April 2007 and May 2009.

Transformation of Electronic Health Records and Questionnaire Data to OMOP CDM: A Feasibility Study Using SG_T2DM Dataset.

Background: Diabetes mellitus (DM) is an important public health concern in Singapore and places a massive burden on health care spending. Tackling chronic diseases such as DM requires innovative strategies to integrate patients' data from diverse sources and use scientific discovery to inform clinical practice that can help better manage the disease. The Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) was chosen as the framework for integrating data with disparate formats.

Timing of tracheal intubation on mortality and duration of mechanical ventilation in critically ill children: A propensity score analysis.

Objective: We aimed to investigate whether early tracheal intubation (TI) is associated with a reduced risk of mortality and increased ventilator-free days (VFD).

Methods: We performed a retrospective cohort study of children 0 to 18 years old in a pediatric intensive care unit (PICU), between 2008 and 2017. Patient demographics, vital signs, and laboratory findings were extracted.
