Low concentrations of air pollutants are associated with poorer health, and previous research has found a link between air pollution and dementia risk. Researchers at Karolinska Institutet, among others, have now investigated this connection. The study, published in the journal Neurology, contributes to a better understanding of the biological mechanisms that might explain why air pollution seems to increase the risk of developing dementia.

Cardiovascular disease is one of the most common causes of death in Sweden and in the world. Researchers at Karolinska Institutet, among others, have now found that artificial intelligence seems to play a role in identifying the risk of cardiovascular disease. The study, published in Cardiovascular Research, may in the future lead to more accurate diagnostic methods.

Children of parents with mental illness are at increased risk of being born too early, especially if it is stress-related, and both the mother’s and the father’s mental health seem to be of importance. This is according to a register-based study from Karolinska Institutet published in PLOS Medicine.

Smartphones and other portable electronics have changed our habits and our society in a couple of decades - but within medicine, the development has only just begun. Everyday gadgets that monitor our health open up new ways to detect, prevent and treat disease - but also raise questions.

Self-harming behaviour in young people causes suffering and increases the risk of suicide. Researchers at Karolinska Institutet and Region Stockholm have now studied if an internet-delivered emotion regulation therapy can reduce self-harm in youth. The study, which is published in JAMA Network Open, suggests that the therapy is effective.

You may know about depression and ADHD - but what about the p factor, emotion regulation and symptom networks? We need more concepts for mental health difficulties, say researchers.

The summer season is typically when the most online fraud attempts and phishing e-mails occur. False invoices are a common variant.

Vaccination protects against severe COVID-19 but not against infection. Researchers at Karolinska Institutet and Danderyd Hospital now show that protection against infection with the new omicron variants is linked to mucosal IgA antibodies, which are not induced by vaccination. These are the findings of two studies recently published in The Lancet Infectious Diseases, and The Lancet Microbe, and could explain the limited protection by currently available vaccines against infection.

Karolinska University Hospital's Director Björn Zoëga and Karolinska Institutet's President Annika Östman Wernerson have signed an agreement to establish a joint center for advanced cell, gene and tissue therapies.

Online cognitive behavioral therapy (CBT) shows promising effects on quality of life, as well as reduced healthcare consumption for patients with paroxysmal (i.e., intermittent) symptomatic atrial fibrillation, according to a new study in the Journal of the American College of Cardiology. According to the researchers, this is the world's first randomized controlled trial of CBT for patients with atrial fibrillation (AF).

The Virus Tech Core Facility has acquired the plasmids necessary for the production of the new variations of the AAV9 pseudotype viruses.

Dear colleagues!

Nicki started on 1 June and is located at the administration office on the 8th floor. Read more about her background and who she is.

We are excited to announce that we are in the process of acquiring a new sorter for our Flow Cytometry Core Facility at Biomedicum. This acquisition aims to expand our sorting capacity, allowing us to better accommodate the needs of our researchers.

We are thrilled to announce the latest additions to our core facility. We have recently acquired two Sony ID7000 spectral analyzers, Alice and Howard. These analyzers are equipped with advanced features, including five lasers and an array of 147 detectors, enabling high-resolution spectral analysis.

Global Child Health and Sustainable Development Goals team members Olivia Biermann and Mariam Claeson are commissioners on the second Lancet Commission on Adolescent Health and Wellbeing. Together they co-lead the commission’s workstream on the political economy of adolescent mental health and well-being. Last month, May 9-11, they visited Nairobi, Kenya for a midterm meeting to present and discuss the progress of the workstreams of the commission.

On behalf of the Public Health Agency of Sweden, researchers at IMM have produced the document "Expert opinion on heated tobacco products”.

KI researchers Georgios Sotiriou and Haipeng Li at the Department of Microbiology, Tumor and Cell Biology have developed an inexpensive, fast, and reproducible manufacturing process of nanosensors for food safety diagnostics.

Hearing loss can lead to anxiety, sadness and depression. Gerhard Andersson has been researching a treatment for those who have difficulty accepting hearing loss.

Mikael Wiehe's hearing loss affects both himself and those around him. Nowadays, he prefers to perform alone, and restaurant visits only work if the sound environment is right. This article is part of an in-depth feature from KI's popular science magazine Medicinsk Vetenskap.

At its meeting of 22 June, the government made the decision to stop all grants disbursed by the Swedish Research Council itemised as development research, effectively pulling the plug on a great deal of planned research in the field. Researchers in the sector have protested publicly against the decision, which has also been condemned by KI president Annika Östman Wernerson.

Ida Bäckström suddenly lost her hearing - first in the right ear and then in the left. Now she hears with the help of cochlear implants. This article is part of an in-depth feature from KI's popular science magazine Medicinsk Vetenskap.

Some children are born with hearing loss in only one ear. What to do then? The issue is more difficult than one might think.

One billion young people risk hearing loss in the future if they continue to listen to their headphones at too high a volume. To develop treatments, researchers need to solve the mysteries of the cochlea - well hidden in the inner ear, a pea-sized organ embedded in bone a few centimeters inside the outer ear.

A groundbreaking study published in Nature Cardiovascular Research uncovers the crucial role of the AmotL2 protein in connecting mechanical forces to endothelial cell integrity and alignment. This discovery sheds light on junctional mechanotransduction and its implications for vascular disease, including abdominal aortic aneurysms (AAA). Importantly, the study reveals gender differences, with males showing a higher incidence of AAA.
