More knowledge is needed about risk factors for recurrent cardiovascular disease and myocardial infarction. In his thesis, doctor Joel Ohm at the Department of Medicine, Solna, Karolinska Institutet, describes how socio-economic factors have a major impact on secondary prevention efforts and prognosis. The results may have an impact on people who have survived myocardial infarction.

A Swedish COVID-19 data portal has now been in operation for a year and forms part of a European network aimed at promoting data sharing and access to data-related resources. The data portal has contributed to increased support for a large number of research projects and publications.

By analyzing 4,000 drugs’ ability to affect cells’ capacity to produce proteins, researchers at Karolinska Institutet found that an anticancer therapy currently trialed in human patients works differently than previously thought. As many human diseases have alterations in this process called translation, the new knowledge contributes to a better understanding of how translation is regulated and the biological routes that regulate it. The study is published in PLOS Biology.

University students in Stockholm reported no tangible differences in depression, anxiety or stress during the first few months of the COVID-19 pandemic, a longitudinal study at Sophiahemmet University and Karolinska Institutet finds.

The human papillomavirus (HPV) can cause cancer and many countries run national vaccination programmes to minimise the risk. Studies involving researchers at German Cancer Research Center, Karolinska Institutet and Tampere University now report on the longitudinal effect of common HPV vaccines. The results, which are published in The Journal of Infectious Diseases and Lancet Infectious Diseases, show lasting protection against more HPV variants than the vaccines were developed for.

Studying the implementation of public health interventions typically involves the identification of “facilitators” and “barriers”. In the case of active tuberculosis case-finding (also referred to as community-based tuberculosis screening), many studies have documented facilitators and barriers, but only few have explored the “how-to” of capitalizing on facilitators and overcoming barriers to put active case-finding into practice. This new study contributes to filling this gap.

Continuous skin-to-skin contact starting immediately after delivery even before the baby has been stabilised can reduce mortality by 25 per cent in infants with a very low birth weight.

For decades, scientists have studied the health benefits of exercise – but this research has largely ignored the fact that how you spend the rest of the day may also matters. Instead of the recommendation that everyone should strive to achieve 150 minutes of weekly exercise, our results show physical activity recommendations can been more personalized. People can adopt a combination of activity that works best for them.

An exciting new way has been found in which the body senses a bacterial infection within 4 hours and uses nerve pathways to trigger an immune response in distant organs. The speed by which an infection can be identified, and how the defence mechanisms are triggered is critical to infection outcome.

MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers at Karolinska Institutet in Sweden are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results published in Advanced Materials Technologies show that the microneedle patch effectively reduces MRSA bacteria in the skin.

Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells. A brain imaging study at Karolinska Institutet now shows that the average level of the serotonin transporter increased in a group of 17 individuals who recovered from depression after cognitive behavioural therapy. The results are published in the journal Translational Psychiatry.

Nine out of ten cases of tuberculosis appear in 30 identified low and middle-income countries, each of which has a national tuberculosis programme. The managers of these programmes agree that it is important to screen for tuberculosis outside of health facilities. However, each screening programme must have its own well-considered, sustainable strategy and sufficient resources for it to be meaningful – which is not always the case today. This is one conclusion drawn by Olivia Biermann’s thesis.

In Sweden, there are over 2 million legally owned firearms. At the same time, up to 150,000 people live with a diagnosis of dementia. In an aging society such as Sweden, legislators will face challenges in gun ownership. A new registry-based observational study by researchers from NVS, Karolinska Institutet, published in the Journal of Alzheimer’s Disease shows a need for strategies for this growing problem.

Karolinska Institutet hopes to establish a new professorship in anti-doping and public health named after Arne Ljungqvist, who turns 90 this year. The university is now seeking donors for the professorship, which can be consequential in the fight against a grown public health problem.

Researchers at Karolinska Institutet have discovered a mechanism through which meningitis-causing bacteria can evade our immune system. In laboratory tests, they found that Streptococcus pneumoniae and Haemophilus influenzae respond to increasing temperatures by producing safeguards that keep them from getting killed. This may prime their defenses against our immune system and increase their chances of survival, the researchers say. The findings are published in PLoS Pathogens.

Researchers at Karolinska Institutet and the Public Health Agency of Sweden have studied newborn babies whose mothers tested positive for SARS-CoV-2 during pregnancy or childbirth. The results show that although babies born of test-positive mothers are more likely to be born early, extremely few were infected with COVID-19. The study, which is published in the esteemed journal JAMA, supports the Swedish recommendation not to separate mother and baby after delivery.
