Background
To promote influenza vaccination coverage, a Chinese megacity, Shenzhen provides free influenza vaccination to its residents aged 60 years and above through community health centres (CHCs) since October 2016. A community health centre-based experiment was conducted by asking primary care physicians (PCPs) working in the intervention health centres to proactively recommend influenza vaccination to their patients aged 60 and above during their patients’ visits.
Methods
This study used an experimental design and a survey design. The experimental design evaluated the effect of PCP recommendation on influenza vaccination. A total of 24 CHCs were randomly selected as the intervention (involving 3814 participants) and control (3072 participants) group evenly. The intervention study period was during the 2017–2018 flu season. The 2016–2017 flu season was considered as the baseline comparison. The survey design examined changes in knowledge, attitude, and practice of influenza vaccination among older participants before and after the free influenza vaccination implementation. We randomly invited 1200 participants aged 60 and above during their visits to CHCs in October 2016 and followed them up until October 2017; among them, 958 participants completed the follow-up survey using the same questionnaire.
Results
In the 2017–2018 flu season, 1,100 more patients got vaccinated in the intervention group under PCP recommendation compared with the 2016–2017 flu season. Among the 958 older adults in the post-implementation period, 77.5% had heard about the influenza vaccine, which was 24.7% higher than in the pre-implementation period; 84.8% of participants were aware where to take influenza vaccines, with the most improvement of 37.2% among all knowledge related questions; 62.5% of them agreed that patients with chronic diseases should have influenza vaccine, which was 19.1% higher than those being surveyed before the implementation period. About 83.6% of participants agreed older adults should have influenza vaccine, but there were still 58.4% who considered themselves too healthy to get vaccinated.
Conclusion
PCP recommendation improved influenza vaccine uptake and knowledge, attitude, and practice levels regarding influenza vaccination among older adults. More health policies and health education should be made to raise vaccination willingness and improve vaccination coverage among older adults.
All-inorganic CsPbBr3 perovskite solar cells (PSCs) without hole-transport materials (HTMs) have attracted widespread attention because of their significant environmental stability. However, the poor quality of perovskite film and the energetics...
Compared to cow milk, buffalo milk contains more protein, fat, and vitamin. Buffalo milk is an ideal food in human life. Sterol regulatory element‐binding protein 1 (SREBP1), an important transcription factor, regulates the expression and activity of enzyme and protein involved in milk fat synthesis to influence on the synthesis and secretion of triglyceride in mammary epithelial cells. In the present study, we successfully isolated buffalo mammary epithelial cell by using enzymatic digestion, and then described the growth characteristics and expression characteristics of mammary epithelial cells. Moreover, we cloned the SREBP1 gene from total RNA isolated from milk fat globule and analyzed the function of the SREBP1 gene. After infected with shRNA‐SREBP1 lentiviral particle and treated with fatty acid, the expression trend of ACACA, FABP3, FAS, SCD, ERK1, ERK2, PPARy, and Insigl genes was consistent with the expression trend of SREBP1 gene. These results suggested that SREBP1 gene is a central transcription factor in regulating milk fat synthesis and SREBP1 gene may act on ERK1/ERK2 signaling pathway to regulate the expression of PPARy gene. The current study will provide a theoretical basis for further reveal the molecular mechanism of milk fat synthesis in buffalo mammary epithelial cells.
Practical applications
This study aim to separate and analysis characterization of mammary epithelial cell in buffalo. Compared to cow milk, buffalo milk contains more protein, fat, and vitamin. Buffalo milk is an ideal food in human life. This study will provide a theoretical basis for further research on the molecular mechanism of milk fat synthesis in buffalo mammary epithelial cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
