In almost ten per cent of myocardial infarctions, no obvious cause in the coronary artery can be found. Some of the patients are diagnosed with broken-heart syndrome, while others are left without a diagnosis. A new study from Karolinska Institutet in Sweden suggests that early magnetic resonance (MR) imaging of the heart can greatly increase the rate of diagnosis. The study has been published in the journal JACC Cardiovascular Imaging.

Researchers at Karolinska Institutet have found links between certain blood groups and a total of 49 diseases, including a new finding that having blood group B seems to be a protective factor against kidney stones. The study, which includes data on more than five million people and over 1,000 diseases, confirms previously identified connections between certain blood groups and increased risk of blood clots, bleeding conditions or pregnancy-induced hypertension. The result is published in eLife.

Researchers at the Centre for Psychiatry Research at Karolinska Institutet have completed a large study evaluating a screening instrument for assessing the risk of suicide in connection with a visit to an emergency psychiatric clinic. The researchers found a link between screening score and suicide risk a short time after the emergency visit. The study is published in the journal Psychological Medicine.

This weekend marks five years since KI alumnus, researcher, and Swedish citizen, Ahmadreza Djalali was arrested and imprisoned in connection with a lecture tour in Iran.

Although hemorrhoids are a common health problem, relatively little is known about the field, possibly because many people find them difficult to talk about. Researchers linked to Karolinska Institutet have been involved in a study that has analysed the genomes of almost a million people and found previously unknown causes of severe hemorrhoids. The study, which is published in the journal Gut, also reveals links to other gastrointestinal diseases.

New biomarkers for Alzheimer’s disease are a priority area for researchers seeking to learn more about the disease and find possible methods of early diagnosis. Researchers at Karolinska Institutet have now studied a new PET tracer that is an important diagnostic tool for the disease. The study on the tracer substance BU99008, which is published in Molecular Psychiatry, can play a key part in the early identification of signs of Alzheimer’s disease.

Patients with atherosclerosis today usually receive preventive treatment only after a heart attack or stroke because diagnostic methods that can identify individuals and atherosclerotic plaques with high-risk are lacking. In addition, the choice of treatment, both surgical and medical, is based on large patient studies and the possibilities for individualizing treatment are small.

The causes of the serious muscle disease ALS still remain unknown. Now, researchers at Karolinska Institutet and KTH Royal Institute of Technology, among others, have examined a type of cell in the brain blood vessels that could explain the unpredictable disease origins and dynamics. The results indicate a hitherto unknown connection between the nervous and vascular systems. The study, published in Nature Medicine, has potential implications for earlier diagnoses and future treatments.

Since March 2020, healthcare has acted "front line" in the fight against COVID-19. Many KI students have worked extra in healthcare during this period, and at the same time, they had to adapt to new routines with distance learning. One of the students who managed to juggle distance learning with an extra job within healthcare is the medical student Oscar Dwyer.

Non-alcoholic fatty liver disease, NAFLD, is associated with several health risks. According to a new registry study led by researchers at Karolinska Institutet in Sweden, NAFLD is linked to a 17-fold increased risk of liver cancer. The findings, published in Hepatology, underscore the need for improved follow-up of NAFLD patients with the goal of reducing the risk of cancer.

Simplifying processes for research-related agreements is one of the main goals of the sub-project within the programme Harmonized professional services.

Histones are tiny proteins that bind to DNA and hold information that can help turn on or off individual genes. Researchers at Karolinska Institutet have developed a technique that makes it possible to examine how different versions of histones bind to the genome in tens of thousands of individual cells simultanously. The technique was applied to the mouse brain and can be used to study epigenetics at a single-cell level in other complex tissues. The study is published in Nature Biotechnology.

Good cholesterol, which is transported in HDLs (high-density lipoproteins), plays a key part in the prevention of atherosclerosis and thus the risk of cardiovascular disease. However, according to a new paper co-authored by researchers at Karolinska Institutet and published in the journal Circulation, the anti-inflammatory properties of HDLs could be an even better biomarker for future cardiovascular events.

As the pandemic lingers on, more and more emphasis is being placed on the indirect, negative effects (i.e. collateral damage) of the pandemic and related restrictions. Sweden took a relatively lenient approach towards mitigating the pandemic during the spring of 2020, relying on voluntary adherence to recommendations and encouraging elderly to stay at home, avoid social gatherings and public transportation, and to remain physically active outdoors in a safe manner.

Joanna Kvist and Maria Eriksson has been appointed professors at the Department of Molecular Medicine and Surgery, Karolinska Institutet.

The standard treatment for advanced metastatic prostate cancer (PCa) is androgen deprivation therapy (ADT). And even if this is efficient in the short term, 1/3 of PCa will become resistant to ADT and develop castration-resistant prostate cancer. A new study, by Karolinska Institutet and others, shows that estrogen receptor β (ERβ) agonists together with ADT could be considered useful in the treatment.

Researchers from Karolinska Institutet, Karolinska University Hospital, and The Wenner-Gren Institute at Stockholm University have conducted research within the field of bacterial meningitis and found how bacteria interact with neurons causing neuronal cell death. The results of their study, which started in 2019, were recently published in PloS Pathogens.

Cholinesterase inhibitors are a group of drugs recommended for the treatment of Alzheimer’s disease, but their effects on cognition have been debated and few studies have investigated their long-term effects.

There are many factors influencing fetal growth – genetic, nutritional, environmental, uteroplacental, and fetal factors. In a new doctoral thesis from Karolinska Institutet, the aim was to further the understanding of the consequences of stress and smoking during pregnancy, the causes of intrauterine growth and asthma as well as the consequences of asthma on school performance and to explore explanations of observed associations.

Climate change can have a detrimental effect on children’s health, yet there are few studies investigating how climate change affects child health. A recent study where researchers compiled 300 articles shows that child health is affected by both direct changes in the near environment, such as increased extreme weather, and by indirect effects, such as air pollution and changing ecosystems. The study was conducted by researchers at Karolinska Institutet and published in Lancet Planetary Health.
