In the last decade, drug development has tackled substantial challenges to improve efficiency and facilitate access to innovative medicines. Integrated clinical protocols and the investigation of targeted oncology drugs in healthy volunteers (HVs) have emerged as modalities with an increase in scope and complexity of early clinical studies and first-in-human (FIH) studies in particular. However, limited work has been done to explore the impact of these two modalities, alone or in combination, on the scientific value and on the implementation of such articulated studies.

In clinical trials, where the outcome of interest is the occurrence of an event over a fixed time period, estimation of the event proportion at interim analysis can form a basis for decision-making such as early trial termination, sample size re-estimation, and/or dropping inferior treatment arms. In addition to derivation of mean squared error under an exponential time-to-event distribution, we performed a simulation study to examine the performance of five estimators of the event proportion when time to the event is assessable. The simulation results showed advantages of the Kaplan-Meier estimator over others in terms of robustness, and the bias and variability of the event proportion estimate.

Introduction: Dental caries, which is prevalent in Singapore preschoolers, is a disease that has a major impact on children's health and places a high cost on the society and health services. Oral health programmes for young children implemented in some parts of the world have been shown to be effective in the prevention of dental caries. We aimed to examine the clinical efficacy of a two-year oral health programme for infants and toddlers in Singapore.

Background: There is paucity of data examining the incidence and outcomes of young OHCA adults. The aim of this study is to determine the outcomes and characteristics of young adults who suffered an OHCA and identify factors that are associated with favourable neurologic outcomes.

Methods: All EMS-attended OHCA adults between the ages of 16 and 35 years in the Pan-Asian Resuscitation Outcomes Study (PAROS) registry were analysed.
