RESUMO
This study aimed to explore the gut microbiota characteristics of ischemic and hemorrhagic stroke patients. A case-control study was conducted, and high-throughput sequencing of the V4-V5 region of 16S rRNA was used to analyze the differences in gut microbiota. The results showed that Proteobacteria was significantly increased in the ischemic stroke group compared with the healthy control group, while Fusobacteria was significantly increased in the hemorrhagic stroke group. In the ischemic stroke group, Butyricimonas, Alloprevotella, and Escherichia were significantly more abundant than in the healthy control group. In the hemorrhagic stroke group, Atopobium, Hungatella, Eisenbergiella, Butyricimonas, Odonbacter, Lachnociostridium, Alistipes, Parabacteroides, and Fusobacterium were significantly more abundant than in the healthy control group. Additionally, Alloprevotella, Ruminococcus, and Prevotella were significantly more abundant in the ischemic stroke group than in the hemorrhagic stroke group. The gut microbiota of ischemic and hemorrhagic stroke patients has significant diversity characteristics. These results provide new theoretical basis for exploring the prevention and treatment of different types of stroke through gut microbiota research.

Factors affecting independence in basic and instrumental activities of daily living have been established in older adults, but not centenarians. The purpose of this study was to examine the state and factors affecting activities of daily living independence in centenarians who resided in Guangxi Province, China. A cross-sectional design was used. Activities of daily living, physical activity, mobility, and physical performance were measured by the Population Study of ChINese Elderly study instruments, and demographics and cognition were assessed. Of the 228 participants, 57% were independent in basic activities of daily living and 5.7% in instrumental activities of daily living. Stepwise regression showed physical activity, cognition, calf circumference, and self-reported health were associated with basic activities of daily living. Physical activity, mobility, cognition, and physical performance were correlated with instrumental activities of daily living. In conclusion, the Chinese centenarians showed impaired instrumental activities of daily living but mostly maintained basic functioning. Physical activity and cognition were associated with activities of daily living independence.
