People with cardiometabolic risk factors such as high blood pressure, obesity and diabetes have an increased risk of life-threatening COVID-19 requiring treatment with invasive ventilation in the intensive care unit. The risk factors are more important in younger people, but there are also clear links between severe COVID-19 and other diseases such as asthma and chronic inflammatory diseases. The researchers believe the findings may be important for future vaccinations in younger age groups.

Almost one in five people lacks the protein α-actinin-3 in their muscle fibre. Researchers at Karolinska Institutet now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibres, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibres. The results are published in The American Journal of Human Genetics.

Researchers at Karolinska Institutet explain that the neurotrophin brain-derived neurotrophic factor (BDNF) binds to the receptor tropomyosin receptor kinase B (trkB) present on the surface of many neurons, triggering signaling pathways critical to the maturation and growth of neurons during development. In their latest article however, they show that BDNF-trkB signaling also plays a significant role in the functioning of the adult brain.

Last year, researchers at Karolinska Institutet and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany showed that a major genetic risk factor for severe COVID-19 is inherited from Neandertals. Now the same researchers show, in a study published in PNAS, that Neandertals also contributed a protective variant. Half of all people outside Africa carry a Neandertal gene variant that reduces the risk of needing intensive care for COVID-19 by 20 percent.

The pandemic has meant that courses and programmes have only had a short time to transition to distance teaching – something which has required major involvement from teachers, students and educational administrators.
