Covid-19 risk increases with airborne pollen

When airborne pollen levels are higher, increased SARS-CoV-2 infection rates can be observed. These results were determined by a large-scale study conducted by an international team headed by researchers at the Technical University of Munich (TUM) and the Helmholtz Zentrum München. Members of high-risk groups could protect themselves by watching pollen forecasts and wearing dust filter masks.

In the spring of 2020, the outbreak of the coronavirus pandemic appeared to coincide with the tree pollen season in the northern hemisphere. These observations prompted an international team of researchers to conduct an extensive investigation: The scientists wanted to know whether there is a demonstrable link between airborne pollen concentrations and SARS-CoV-2 infection rates.

Pollen is a significant environmental factor influencing infection rates
Based on CK-CARE research and under the leadership of first author Athanasios Damialis, the team at the Chair of Environmental Medicine at TUM collected data on airborne pollen concentrations, weather conditions and SARS-CoV-2 infections – taking into consideration the variation of infection rates from one day to another and the total number of positive tests. In their calculations, the team also included data on population density and the effects of lockdown measures. The 154 researchers analyzed pollen data from 130 stations in 31 countries on five continents.

„Wearing a particle filtering mask when pollen concentrations are high can keep both the virus and pollen out of the airways.”— Prof. Claudia Traidl-Hoffmann

The team showed that airborne pollen can account for, on average, 44 percent of the variation in infection rates, with humidity and air temperature also playing a role in some cases. During intervals without lockdown regulations, infection rates were on average 4 percent higher with every increase of 100 grains of airborne pollen per cubic meter. In some German cities, concentrations of up to 500 pollen grains per cubic meter per day were recorded during the study – which led to an overall increase in infection rates of more than 20 percent. In regions where lockdown rules were in effect, however, the infection numbers were on average only half as high at comparable pollen concentrations.

Certification by the Swiss Biobanking Platform – VITA-Label

Building up a proper Governance through accountable mechanisms is key to foster trustworthiness and the pre-requisite for the appropriate use of biological resources. Our CK-CARE Biobank has recently been awarded by Swiss Biobanking Platform (SBP) with the VITA Label, which demonstrates compliance with the applicable legal and ethical framework. This labelling approach is part of our long-term strategy to strengthen biobanking practices and provide high-quality samples to the research community.

CK-CARE Team Meeting October 10th- 11th, 2022

This year’s CK-CARE team event in Davos focused on strengthening cross-center communication and collaboration. Our team members got to know each other and the canton of Grisons better by producing several Grisons specialties as “cross-center team building” in preparation for the scientific work. This as a goal to promote teamwork! Although there was no knowledge about the production of Graubünden delicacies, let alone anyone with appropriate skills, each team excelled in its own way. Driven by trust, respect and genuine motivation to solve the tasks set, the team members met the challenge of working together with fun and creativity as an important preparation for the following day’s research activities. It was a successful meeting – we look forward to many more.

Certification by the Swiss Biobanking Platform – OPTIMA-Label

Davos BioSciences AG achieved the official OPTIMA label of the Swiss Biobanking Platform for its biobank infrastructure as of 30.05.2022. This is another important step for Davos BioSciences AG and CK-CARE. The label attests to the full implementation of a QM system. The OPTIMA-Label confirms: “Compliance with the Good Biobanking Practices; in particular OECD Best practice guidelines for biological resource centres (2007), ISBER Best practices (2018) and IARC Common minimum technical standards (2017). It follows established standards, including the ISO 20387:2018 – general requirements for biobanking. This certification approach is part of our long-term strategy to provide high-quality samples to the research community”.

Certification by the Swiss Biobanking Platform

After some effort, Davos BioSciences AG achieved the official NORMA label of the Swiss Biobanking Platform for its biobank infrastructure as of 17.08.2021. This is an important step for Davos BioSciences AG and CK-CARE. The NORMA-Label confirms: “Compliance with professional standards is essential to perform our daily biobanking activities according to Good Biobanking Practices; in particular OECD Best practice guidelines for biological resource centres (2007), ISBER Best practices (2018) and IARC Common minimum technical standards (2017). It follows established standards, including the ISO 20387:2018 – general requirements for biobanking. This certification approach is part of our long-term strategy to provide high-quality samples to the research community”. Certificate of the Swiss Biobanking Plattform

Claudio Rhyner, PhD appointed as the new Managing Director

On 1 October 2020, Claudio Rhyner succeeded Dr. Georg Schäppi as Managing Director of CK-CARE. Georg Schäppi was appointed CEO at the University Children’s Hospital Zurich as of 1 December, 2020.

Claudio Rhyner was born and grew up in Davos. After studying chemistry and molecular biology, he graduated specialising in asthma and allergy research. He was active in fundamental scientific research, including as head of the research “Vaccine Development” group at the SIAF (Swiss Institute of Allergy and Asthma Research). In this capacity he published numerous publications and filed several patents. After holding a leading position in a SME in molecular diagnostics, he became CEO of Biosciences Davos. Biosciences Davos is a spin-off organisation of CK-CARE in the field of biobanking and is part of the Medizincampus Davos. He continues to hold this position.

In his private life, Claudio Rhyner is actively engaged in politics and culture in the Davos community. He also completed a postgraduate degree in the field of management of small and medium-sized companies at the University St. Gallen.

Atopic dermatitis: an expanding therapeutic pipeline for a complex disease

Our founder, Prof. Thomas Bieber, published an important contribution in the treatment of AD:

Atopic dermatitis (AD) is a common chronic inflammatory skin disease with a complex pathophysiology that underlies a wide spectrum of clinical phenotypes. AD remains challenging to treat owing to the limited response to available therapies. However, recent advances in understanding of disease mechanisms have led to the discovery of novel potential therapeutic targets and drug candidates

In addition to regulatory approval for the IL-4Ra inhibitor dupilumab, the anti-IL-13 inhibitor tralokinumab and the JAK1/2 inhibitor baricitinib in Europe, there are now more than 70 new compounds in development. This Review assesses the various strategies and novel agents currently being investigated for AD and highlights the potential for a precision medicine approach to enable prevention and more effective long-term control of this complex disease.
