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.

Be resilient, work hard – and have fun! In a conversation about their journey to becoming professors, Erika Franzén and Maria Hagströmer gave good advice to junior researchers.

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.

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.
