- Variables Associated with Coronavirus Disease 2019 Vaccine Hesitancy Amongst Patients with Neurological Disorders Sat, 25 Sep 2021 06:00:00 -0400
CONCLUSION: Upon identifying the variables associated with vaccine hesitancy amongst patients with neurological disorders, our clinic is now able to efficiently provide ancillary COVID-19 education to sub-populations at risk for vaccine hesitancy. While our results may be limited to the sub-population of patients with neurological disorders, the findings nonetheless provide valuable insight to understanding vaccine hesitancy. - Determinants of Influenza Vaccination Coverage among Greek Health Care Workers amid COVID-19 Pandemic Sat, 25 Sep 2021 06:00:00 -0400
In the context of the evolving current COVID-19 pandemic, influenza vaccination among the public and health care workers is of particular importance. There are sparse data on the influenza vaccination coverage among health care workers amid COVID-19 pandemic. We aimed to study possible factors associated with influenza vaccination coverage among Greek physicians, dentists, and pharmacists during the flu season 2020-2021. We formulated the hypothesis that COVID-19 pandemic exerted a positive... - Improved pathogenicity of H9N2 subtype of avian influenza virus induced by mutations occurred after serial adaptations in mice Sat, 25 Sep 2021 06:00:00 -0400
H9N2 subtype, a low pathogenic avian influenza virus, is emerging as a major causative agent circulating poultry workplaces across China and other Asian countries. Increasing case number of interspecies transmissions to mammals reported recently provoked a great concern about its risks inducing global pandemics. In an attempt to understand the underlying mechanism of how the H9N2 virus disrupts the interspecies segregation to transmit to mammals. A mutant H9N2 strain was obtained by passaging... - Is it possible to hospitalize patients in multiple-bed room without increasing the risk of hospital-acquired influenza? Description of a pragmatic preventive strategy in a French university hospital Sat, 25 Sep 2021 06:00:00 -0400
CONCLUSION: These preliminary results suggest that the occurrence of HAI in multiple-bed rooms can be limited by the implementation of maximum precautions and urge us to promote further evaluation of the strategy. A detection bias should be considered without a systematic neighbors monitoring. - Influenza vaccination among caregivers and household contacts of children with congenital heart disease before and during COVID-19 pandemic Sat, 25 Sep 2021 06:00:00 -0400
CONCLUSIONS: Vaccination coverage of caregivers and household contacts of children with CHD is suboptimal. Influenza vaccination campaigns should take into consideration the specific characteristics of parental groups and target interventions accordingly to increase their vaccine uptake and indirectly protect children with CHD. - Proteolytic activation of SARS-CoV-2 spike protein Sat, 25 Sep 2021 06:00:00 -0400
Spike (S) protein cleavage is a crucial step in coronavirus infection. In this review, we discuss this process, with particular focus on the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Compared with influenza virus and paramyxovirus membrane fusion proteins, the cleavage activation mechanism of coronavirus S protein is much more complex. The S protein has two cleavage sites (S1/S2 and S2'), and the cleavage motif for furin protease at the S1/S2 site that... - Covalent functionalization of polypropylene filters with diazirine-photosensitizer conjugates producing visible light driven virus inactivating materials Sat, 25 Sep 2021 06:00:00 -0400
The SARS-CoV-2 pandemic has highlighted the weaknesses of relying on single-use mask and respirator personal protective equipment (PPE) and the global supply chain that supports this market. There have been no major innovations in filter technology for PPE in the past two decades. Non-woven textiles used for filtering PPE are single-use products in the healthcare environment; use and protection is focused on preventing infection from airborne or aerosolized pathogens such as Influenza A virus or... - The antimicrobial peptide S100A8/A9 produced by airway epithelium functions as a potent and direct regulator of macrophage phenotype and function Sat, 25 Sep 2021 06:00:00 -0400
Elevated counts of alveolar macrophages and attenuated phagocytic capacity are associated with COPD. Factors governing macrophage phagocytosis are poorly understood. In this study we aimed to compare the influence of airway epithelial cell secretions from COPD and nonCOPD subjects on macrophage phagocytic activity, and the role of antimicrobial peptides (AMPs).Supernatants from nonCOPD and COPD small airway epithelial cell (SAEC) cultures exposed to Haemophilus influenzae (NTHi), were applied to... - Influenza vaccine uptake among at-risk adults (aged 16-64 years) in the UK: a retrospective database analysis Sat, 25 Sep 2021 06:00:00 -0400
CONCLUSIONS: Uptake of the influenza vaccine by adults aged 16-64 years in a clinical at-risk group was substantially below the national ambitions. As a result, many individuals in the UK remain at high risk of developing severe influenza or complications. Given that people who are vulnerable to COVID-19 are also at increased risk of complications from influenza, during the 2020-2021 season, there is a heightened need for healthcare professionals across the UK to address suboptimal vaccine... - Childhood vaccination uptake and associated factors among children 12-23 months in rural settings of the Gambia: a community-based cross-sectional study Sat, 25 Sep 2021 06:00:00 -0400
CONCLUSION: There is moderately a burden of incomplete vaccination in rural Gambia. Vaccination programs should be constantly monitored and evaluated by the Ministry of Health, especially in rural areas. To increase societal awareness and vaccine acceptance, a robust community-based health education efforts are desperately needed as part of initiatives to increase vaccine service utilization for these high-risk classes.
