Hepatitis A infections from food.
2020
Food contaminated by hepatitis A virus (HAV) is responsible of the 2–7% of all HAV outbreaks worldwide. This review provides a description of the HAV characteristics, its infectivity and epidemiological features. In addition, this review compiles existing original papers reporting HAV prevalence, viral titres in foodstuffs and the risk associated with food contamination. The purpose of this revision is to conduct a structured and systematic review of the published molecular procedures for HAV detection in food, including the assessment of its infectivity.

Differential requirements for antigen or homeostatic cytokines for proliferation and differentiation of human Vgamma9Vdelta2 naive, memory and effect…
2005
We have compared four human subsets of Vgamma9Vdelta2 T cells, naive (T(naive), CD45RA(+)CD27(+)), central memory (T(CM), CD45RA(-)CD27(+)), effector memory (T(EM), CD45RA(-)CD27(-)) and terminally differentiated (T(EMRA), CD45RA(+)CD27(-)), for their capacity to proliferate and differentiate in response to antigen or homeostatic cytokines. Cytokine responsiveness and IL-15R expression were low in T(naive) cells and progressively increased from T(CM) to T(EM) and T(EMRA) cells. In contrast, the capacity to expand in response to antigen or cytokine stimulation showed a reciprocal pattern and was associated with resistance to cell death and Bcl-2 expression. Whereas antigen-stimulated cells a…
Fear of COVID-19 as a buffer in the relationship between perceived stress and life satisfaction in the Polish population at the beginning of the glob…
2020
BackgroundCOVID-19 is a significant threat to human life and health. It makes people experience fear, stress, anxiety and mood disor-ders, which have a negative impact on their psychological well-being. The aim of the study was to determine the relation-ship between fear of COVID-19, perceived stress, and life satisfaction during the coronavirus pandemic.Participants and procedure907 Polish people (522 women and 385 men) participated in this study. The Perceived Stress Scale (PSS-10), the Fear of COVID-19 Scale (FOC-6) and the Satisfaction with Life Scale (SWLS) were used in the study.ResultsFear of COVID-19 and perceived stress were positively correlated with each other and both negatively…
Intentional interruptions during compression only CPR: a way to increase adherence to CPR and compressions' quality?

2020
The biological anakinra appears promising to halt cytokine storm syndrome seen in severe courses of COVID-19. However, immunosuppression with anakinra may facilitate sepsis, necessitating continuous screening for bacterial superinfections.
Arthralgia as an early extraintestinal symptom of Whipple's disease. Report of five cases.
1997
Five patients with Whipple's disease all suffered from arthralgia for a long time (15 years in one case) before developing gastrointestinal or other symptoms. In all patients, arthralgia was seronegative, and there was no evidence of joint destruction. Arthralgias were symmetric and migrating. Whipple's disease is part of the differential diagnosis of enteropathic arthralgia. Thereby, the polymerase chain reaction can be a helpful tool to prove Whipple's disease in difficult differential diagnosis.
The Epidemiology of Hip and Knee Primary and Revision Arthroplasties during the COVID-19 Pandemic
2021
Background: The purpose of this study was to provide a comprehensive assessment of the impact of the COVID-19 pandemic on the epidemiology of primary and revision arthroplasties of the hip and knee joint. Methods: This study compared the data on knee and hip arthroplasty procedures from 2 hospitals (primary and revision) conducted in two periods: the period of the COVID-19 pandemic in Poland (from 4 March 2020 to 15 October 2020) and the corresponding period prior to the pandemic (from 4 March 2019 to 15 October 2019). We compared the epidemiological data, demographic data, and hospital stay duration data from these two periods. Results: Our analysis demonstrated that the total number of hi…
A Crowd-Sourced Database of Coronamusic: Documenting Online Making and Sharing of Music During the COVID-19 Pandemic
2021
When a sweeping COVID-19 pandemic forced cultural venues, schools, and social hangouts into hibernation in early 2020, music life relocated to the digital world. On social media platforms like YouTube, Facebook, Twitter, and TikTok, sofas and balconies took center stage for musical performances presented as live-streamed concerts and recorded videos. Amateurs and professional musicians alike embraced digital formats and innovated novel genres of corona-themed music. We will refer to the products of this musical phenomenon collectively as "coronamusic." Adapting a well-known term from cultural musicology (Small, 1999), the diverse practices of listening, playing, dancing, composing, rehearsi…
Desarrollo y aplicación experimental de vectores virales basados en genomas de coronavirus para prevenir infecciones por rotavirus.
2009
Las infecciones por rotavirus son la causa más importante de gastroenteritis en niños menores de cinco años de edad. Se calcula que provocan unas 600.000 muertes anuales, principalmente en los países en vías de desarrollo. Una de las estrategias más prometedoras de desarrollo de nuevas vacunas consiste en el uso de virus recombinantes. Entre los sistemas virales de expresión de proteínas recombinantes más interesantes se encuentran los coronavirus. En este trabajo se aborda la producción de vectores virales basados en genomas del coronavirus TGEV (virus de la gastroenteritis porcina transmisible) para aplicarlos como vacunas experimentales de las infecciones por rotavirus. Para ello se han …
