Implementing Acute Stroke Services in sub-Saharan Africa: Steps, Progress and Perspectives from the Tanzania Stroke Project

Stroke is a leading cause of morbidity and mortality globally, with Africa bearing a disproportionately high burden of poor outcomes. In sub-Saharan Africa, acute stroke care remains inconsistent, with organized stroke units being either absent or rarely available, contributing to the high stroke mortality rates in the region. To address this issue, the Tanzania Stroke Project (TSP) was launched, aimed at establishing acute stroke services at two of the largest tertiary care centers in collaboration with the Tanzanian Ministry of Health, the World Stroke Organization and Hospital Directorates

Visualizing disparities in park access for the elderly in Shanghai, China

With China ageing rapidly, the health of the elderly has become a public concern. Access to urban parks, offering both physical and psychological health benefits to people, is critical for the elderly. To explore whether there are disparities in park access for the elderly, we collected and processed population data, point of interest and travel time from census tracts to parks by public transport in Shanghai. The visuals based on the data indicate that, in Shanghai, most of the elderly are able to reach large parks in 30 minutes, but gaps remain in the number of accessible parks. Although the ageing population living between the inner ring road and the external ring road is as large as that inside the inner ring road, the number of accessible parks for this population is much lower than for the latter. </jats:p

Reverse traffic flows: Visualizing a new trend in Spring Festival travel rush in China

Traditionally, Chinese would go back to their hometowns to reunite with their families during the Chinese Lunar New Year. In the last 30 years, due to the uneven development of regions, Spring Festival travel rush were mainly from large cities to small cities or rural areas. However, in recent years, an increasing number of migrants prefer to stay in larger cities and have their families visit them during the Spring Festival. To map the reverse migrations and explore their influence, we collected and processed data on passenger travel in 2017 and 2018 from Tencent Location Big Data and GDP in 2017 at the prefectural level. The visuals based on the data indicate that the volume of reverse migration was mainly concentrated in regional centers, with great variation across cities. Besides, with increasing reverse traffic flows, large cities are shifting from being empty to vibrant cities during the Spring Festival, while small cities and rural areas are losing their vibrancy. </jats:p
