Beyond the Educational Context: Relevance of Intrinsic Reading Motivation During COVID-19 Confinement in Spain
2021
What role could have intrinsic motivation toward reading in an extraordinary situation like the recent confinement? This research examines the relationship between intrinsic reading motivation (IRM) and reading habits in an adult population considering types of reading (for leisure, work/study, social networks, and news), gender, and distress generated by the coronavirus disease 2019 (COVID-19) pandemic. Participants were 3,849 adults from Spain who were surveyed about their reading practices: before, during the first weeks, and after several weeks of confinement. Linear mixed effects models (LMMs) were used to analyze data. Results showed a three-way interaction between reading frequency, …
Ventilator-Associated Pneumonia in Patients with COVID-19: A Systematic Review and Meta-Analysis
2021
The aim of this systematic review and meta-analysis was to estimate the pooled occurrence of ventilator-associated pneumonia (VAP) among patients admitted to an intensive care unit with COVID-19 and mortality of those who developed VAP. We performed a systematic search on PubMed, EMBASE and Web of Science from inception to 2nd March 2021 for nonrandomized studies specifically addressing VAP in adult patients with COVID-19 and reporting data on at least one primary outcome of interest. Random effect single-arm meta-analysis was performed for the occurrence of VAP and mortality (at the longest follow up) and ICU length of stay. Twenty studies were included in the systematic review and meta-an…
An assessment of COVID-19’s impact on Finnish University Leadership
2021
This article maps the management actions that Finnish universities have taken during the COVID-19 pandemic and studies how managers in Finnish higher education coped during the crisis and how they feel about it. The article uses action mapping and a survey that was administered to top- and mid-level managers at Finnish universities, and the findings highlight the importance of collegial coordination and maintenance work abilities among managers. publishedVersion Peer reviewed
Rodent host population dynamics drive zoonotic Lyme Borreliosis and Orthohantavirus infections in humans in Northern Europe
2021
Zoonotic diseases, caused by pathogens transmitted between other vertebrate animals and humans, pose a major risk to human health. Rodents are important reservoir hosts for many zoonotic pathogens, and rodent population dynamics affect the infection dynamics of rodent-borne diseases, such as diseases caused by hantaviruses. However, the role of rodent population dynamics in determining the infection dynamics of rodent-associated tick-borne diseases, such as Lyme borreliosis (LB), caused by Borrelia burgdorferi sensu lato bacteria, have gained limited attention in Northern Europe, despite the multiannual abundance fluctuations, the so-called vole cycles, that characterise rodent population d…
Crystallization and preliminary crystallographic analysis of the major capsid proteins VP16 and VP17 of bacteriophage P23-77.
2012
The major capsid proteins VP16 and VP17 of bacteriophage P23-77 have been crystallized using both recombinant and purified virus and preliminary diffraction analyses have been performed.
Paramedics’ knowledge of medical guidelines and procedures for protection against coronavirus during the COVID-19 pandemic: a pilot study
2021
Background: Paramedics are the frontline workers of the healthcare profession. Thus, they need to be equipped with the relevant knowledge, skills, and protective gear against different forms of infection, including coronavirus disease 2019 (COVID-19). Aim of the study: To determine the level of paramedics’ knowledge about implementing medical guidelines and procedures to avoid coronavirus infection during the COVID-19 pandemic. Material and methods: This study involved 101 paramedics employed in Emergency Medical Services in Legnica between November 2020 and January 2021. A diagnostic survey method and opinion polling technique were applied. A survey developed by the study authors was used.…
Sphingomyelin induces structural alteration in canine parvovirus capsid
2008
One of the essential steps in canine parvovirus (CPV) infection, the release from endosomal vesicles, is dominated by interactions between the virus capsid and the endosomal membranes. In this study, the effect of sphingomyelin and phosphatidyl serine on canine parvovirus capsid and on the phospholipase A2 (PLA2) activity of CPV VP1 unique N-terminus was analyzed. Accordingly, a significant (P ≤ 0.05) shift of tryptophan fluorescence emission peak was detected at pH 5.5 in the presence of sphingomyelin, whereas at pH 7.4 a similar but minor shift was observed. This effect may relate to the exposure of VP1 N-terminus in acidic pH as well as to interactions between sphingomyelin and CPV. When…
