Background: Since the beginning of the COVID-19 outbreak in December 2019, a substantial body of COVID-19 medical literature has been generated. As of June 2020, gaps and longitudinal trends in the COVID-19 medical literature remain unidentified, despite potential benefits for research prioritisation and policy setting in both the COVID-19 pandemic and future large-scale public health crises.Methods: In this paper, we searched PubMed and Embase for medical literature on COVID-19 between 1 January and 24 March 2020. We characterised the growth of the early COVID-19 medical literature using evidence maps and bibliometric analyses to elicit cross-sectional and longitudinal trends and systematically identify gaps.Results: The early COVID-19 medical literature originated primarily from Asia and focused mainly on clinical features and diagnosis of the disease. Many areas of potential research remain underexplored, such as mental health, the use of novel technologies and artificial intelligence, pathophysiology of COVID-19 within different body systems, and indirect effects of COVID-19 on the care of non-COVID-19 patients. Few articles involved research collaboration at the international level (24.7%). The median submission-to-publication duration was 8 days (interquartile range: 4-16).Conclusions: Although in its early phase, COVID-19 research has generated a large volume of publications. However, there are still knowledge gaps yet to be filled and areas for improvement for the global research community. Our analysis of early COVID-19 research may be valuable in informing research prioritisation and policy planning both in the current COVID-19 pandemic and similar global health crises.

The objective of this paper is to examine short-term trends in the prevalence of limitation in Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL) and Nagi physical functioning tasks among persons age 60 years or older in five Asian settings: Indonesia, the Philippines, Singapore, Taiwan and the Beijing Municipality. The data come from recent panel surveys of older adults that span a period of 3-4 years during the mid to late 1990s. Results suggest a general trend toward an increase in functional limitation in four of the five settings, with the most pronounced increases occurring for the Nagi functioning tasks. Compositional differences in the population accounted for little of the increase. The paper discusses the potential implications of these results and places them in the context of past and current trends in functional limitation observed in the United States.
