Aim
To investigate intention rates to get vaccinated against COVID-19 among healthcare personnel (HCP) in Greece.
Methods
Cross-sectional survey.
Results
The response rate was 14.5%. Of 1,521 HCP with a known profession, 607 (39.9%) were nursing personnel, 480 (31.6%) physicians, 171 (11.2%) paramedical personnel, 72 (4.7%) supportive personnel, and 191 (12.6%) administrative personnel. Overall, 803 of 1,571 HCP (51.1%) stated their intention to get vaccinated while 768 (48.9%) stated their intention to decline vaccination. Most HCP (71.3%) who reported intent to get vaccinated noted contributing to the control of the pandemic and protecting their families and themselves as their reasons, while the most common reason for reporting intent to decline vaccination was inadequate information about the vaccines (74.9%), followed by concerns about vaccine safety (36.2%).Logistic regression analysis revealed that the probability of intending to get vaccinated increased with male gender, being a physician, history of complete vaccination against hepatitis B, history of vaccination against pandemic A (H1N1) in 2009-2010, belief that COVID-19 vaccination should be mandatory for HCP, and increased confidence in vaccines in general during the COVID-19 pandemic. The following factors were associated with a lower intention to get vaccinated: no vaccination against influenza the past season, no intention to get vaccinated against influenza in 2020-2021, and no intention to recommend COVID-19 vaccination to high-risk patients.
Conclusions
There is an urgent need to built safety perception towards COVID-19 vaccines and raise vaccine uptake rates by HCP, and thus to protect the healthcare workforce and the healthcare services.
Idiopathic pulmonary fibrosis (IPF) is associated with aberrant repair, persistence of collagen deposition, and the development of vascular remodeling. However, the role of angiogenesis in the pathogenesis of IPF is still undetermined. The aim of this study was to evaluate the combined mRNA expression of vascular endothelial growth factor A (VEGFA), fibroblast growth factor 2 (FGF2), insulin-like growth factor 1 (IGF1) epidermal growth factor (EGF), and its receptor (EGFR) in lung tissue obtained from IPF patients. We have also investigated the expression of chemokine CXCL12/stromal cell-derived factor-1 (SDF-1) and its receptor, CXCR4, to identify alterations that maybe implicated in the pathogenesis of IPF. The subjects studied consisted of two distinct groups: patients with IPF (n = 25) and subjects (control) undergoing thoracic surgery for reasons other than interstitial lung disease (n = 10). Expression analysis of the aforementioned growth factors and biological axis CXCL12/CXR4 analysis were performed using real-time RT-PCR. IGF-1, EGF, and FGF2 mRNA levels are significantly decreased in the patients compared to the controls (p = 0.028, p = 0.023 and p = 0.009, respectively). SDF1-TR1 and SDF1-TR2 transcript levels were significantly lower in patients compared to controls (p = 0.017 and p = 0.001). Significant coexpression of VEGF mRNA with IGF mRNA was observed in the group of the patients (p = 0.017). An additional coexpression of VEGF mRNA with SDF1-TR1 mRNA was demonstrated(p = 0.030). Our results show a downregulation in angiogenetic mechanisms in IPF. However, our results should be further verified by measuring other angiogenetic pathways in more samples.
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.
