Targeted micronutrition ameliorates allergy symptoms
Targeted micronutrition ameliorates allergy symptoms
Micronutrient deficiencies can promote inflammation and render the immune system particularly sensitive to allergenic substances. In particular, iron deficiency signals danger to immune cells and leads to a more pronounced, exaggerated immune response. For the first time, scientists at the Messerli Research Institute of MedUni Vienna, Vetmeduni Vienna and the University of Vienna conducted a placebo-controlled trial and showed that targeted dietary measures can reduce the symptom burden in allergic reactions.

Consistently high willingness to receive an annual COVID-19 booster vaccination
Consistently high willingness to receive an annual COVID-19 booster vaccination
In view of the constant emergence of new viral variants and the limited duration of immune protection through recovery or vaccination, it is becoming increasingly likely that an annual COVID-19 booster vaccination might be needed. Working with colleagues from the Transatlantic Research Lab on Complex Societal Challenges, Jakob Weitzer and Eva Schernhammer from the Department of Epidemiology at the Medical University of Vienna and Gerald Steiner from the University of Continuing Education Krems investigated the willingness of the population to be vaccinated annually against COVID-19.

Mindfulness as a key to success in psychotherapy
Mindfulness as a key to success in psychotherapy
New statistical method applied for the first time Mindfulness is the ability to focus one's attention on the present moment and to approach the resulting impressions, thoughts, and feelings with curiosity, openness, and acceptance. A team of psychologists from the University of Vienna led by Ulrich Tran now shows in a comprehensive review that the increase of mindfulness not only explains the positive effect of meditation and similar treatments on mental health, but also of psychotherapeutic treatments in which meditation plays no role at all.
