College students' knowledge base on COVID-19 is usually substantial, and they might encourage COVID-19 vaccination campaigns within their families. We intend to comprehend college students' willingness to champion COVID-19 vaccination among their grandparents, and to assess the consequences of their influence.
A combined experimental and cross-sectional study will be performed online. Eligible participants for the cross-sectional study (Phase I) are college students aged 16 and possess at least one living grandparent who is 60 years or older and have or have not been vaccinated for COVID-19. Participants complete Questionnaire A, a self-report instrument, to acquire data on their personal and their grandparents' socio-demographics, alongside their knowledge of COVID-19 vaccinations for older adults, and pertinent Health Belief Model (HBM) and Theory of Planned Behavior (TPB) variables. The initial phase's primary evaluation focuses on the degree to which college students can sway their grandparents towards accepting COVID-19 vaccinations. Those willing to advocate for their grandparents' participation and complete a follow-up survey will be enrolled in a randomized controlled trial (Phase II). Phase II enrollment is restricted to those participants with at least one living grandparent of 60 years or more of age, having completed the initial COVID-19 vaccination regimen and not having received a booster dose. At the outset of the study, participants completed Questionnaire B, providing details about individual grandparents' COVID-19 vaccination status, their perspectives on, and their projected actions regarding, a COVID-19 booster dose. Participants will be randomly assigned to receive either a one-week smartphone-based health education program on COVID-19 vaccination for older adults, followed by two weeks of observation (the intervention arm), or a three-week waiting period (the control arm). Nirogacestat cell line Upon the culmination of the third week, participants in both treatment groups complete Questionnaire C to gather data regarding their grandparents' COVID-19 vaccine status. Among grandparents, the rate of COVID-19 booster dose uptake constitutes the primary Phase II outcome. Grandparents' stance on, and projected actions concerning, a COVID-19 booster dose, constitute secondary outcomes.
No prior investigation quantified the impact of college student persuasion strategies on COVID-19 vaccination rates among senior citizens. This investigation's conclusions will provide substantiation for novel and conceivably viable interventions to advance COVID-19 vaccination within the older adult demographic.

The objective of this research was to investigate the association between color Doppler flow imaging (CDFI) grade and type and the presence of tumor-related cytokines in elderly individuals with colon cancer.
From July 2020 through June 2022, Zhejiang Provincial People's Hospital enrolled seventy-six elderly patients with colorectal cancer for the research. CDFI was utilized to analyze the grade and distribution of blood flow in tumor tissues, and serum cytokine levels were determined by ELISA. The preoperative clinical information was collected and analyzed; furthermore, a study was carried out to determine the correlation between measured cytokine levels and CDFI analysis findings.
A statistically significant disparity in CDFI blood flow grade was observed across varying tumor lengths, invasion depths, and lymph node metastasis counts (all P<0.001). Moreover, there were statistically significant differences in serum TNF-, IL-6, and VEGF levels, considering each of the different tumor-related factors presented (all P<0.001). A significant positive correlation, as revealed by Pearson correlation analysis, was observed between CDFI blood flow grade and distribution types and elevated serum cytokine levels (r>0, all P<0.001). The Kaplan-Meier survival analysis highlighted that CDFI blood flow grade and distribution types served as adverse prognostic indicators for elderly patients with colon cancer. hepatocyte differentiation The regression analysis demonstrated that serum TNF-, IL-6, and VEGF levels were independently associated with a less favorable prognosis for elderly colon cancer patients.
Correlations between CDFI blood flow grade, tumor tissue distribution, and tumor-associated cytokines in the serum might be substantial in colon cancer patients. The CDFI blood flow grading method offers valuable imaging insights into the dynamic changes in angiogenesis and blood flow experienced by elderly patients with colon cancer. Serum levels of tumor-associated factors undergoing abnormal fluctuations can serve as sensitive markers for assessing the therapeutic outcomes and long-term prospects of colon cancer patients.
The potential for significant correlations exists between CDFI blood flow grade, tumor tissue distribution, and tumor-associated cytokines in the serum of colon cancer patients.
