Researchers at Karolinska Institutet and Danderyd Hospital have followed participants who have received three doses of the SARS-CoV-2 vaccine and compared their immune responses after Omicron infection. The results, which are published in The Lancet Infectious Diseases, show that Omicron infection elicits significantly higher antibody responses in individuals without prior COVID-19 infection as compared to previously infected individuals.

On 7 and 8 June 2022, researchers from all over Europe, Israel, the United States and Canada gathered at Karolinska Institutet to discuss the research and latest developments in the I-CARE4OLD project, an EU-funded project launched in 2021.

Researchers at Karolinska Institutet in Sweden show how a molecule that they have identified stimulates the formation of new insulin-producing cells in zebrafish and mammalian tissue, through a newly described mechanism for regulating protein synthesis. The results are published in Nature Chemical Biology.

A study from Karolinska Institutet sheds new light on the question of whether the sex and previous pregnancy of blood donors affects survival in patients who receive red blood cell transfusions. According to the study, which is published in JAMA Internal Medicine, neither of these factors has such an effect, after accounting for the lower haemoglobin levels in blood from women.

In the spring of 2022, the network Senior Faculty at KI conducted a survey on the activities of KI professors born in or before 1953. The results show that the professors are still heavily engaged in research and bring close to SEK 300 million a year into the university.  

Antibiotic resistance is sometimes referred to as the silent pandemic – a contagion that spreads without us really knowing its extent or severity. But research is in progress to find new ways of fighting bacteria. And as with COVID-19, everyone can help to reduce the spread – and save lives.

Broad-spectrum antibiotics are overused in dentistry because many patients mistakenly believe they have a penicillin allergy. But such allergies are rare and should be investigated by a doctor, says Bodil Lund, chair of the Tandvårds-Strama network, which supports rational antibiotic therapy in dentistry.

KI alumni Malin Grape has been appointed by the government as AMR ambassador. But what does that mean?

Pernilla Rönnholm lost her daughter because of antibiotic resistant intestinal bacteria. Now she works for preventing more children to being affected.

New findings reveal an advanced, unexpected two-way communication between the function and organization of chromosomes in the cell nucleus. Previous research shows that the organization of chromosomal DNA into loops regulates gene reading (transcription) and chromosome copying (replication). The new results show that, in turn, transcription and replication control chromosome looping, thus revealing a new interplay known to be important in avoiding diseases, such as cancer.

Measuring the full complement of small molecules (the metabolome) can provide important insight into the health status of an individual. The measurement of metabolites is also the main theme of the recently established KI core facility for small molecule mass spectrometry (KI-SMMS). We talk with Craig Wheelock, Head of the newly founded Unit of Integrative Metabolomics in the Institute of Environmental Medicine (IMM), about the role of metabolomics in personalized health care.

Researchers at Karolinska Institutet in Sweden might have found an explanation for why people with self-injury behaviour generally feel less pain than others. The key seems to be a more effective pain-modulation system, a discovery that can benefit people seeking help for their self-harm. The findings are published in the journal Molecular Psychiatry.

End-stage liver disease (ESLD), including advanced liver cirrhosis and primary liver cancer, is the final stage of long-standing injury to the liver due to risk factors such as chronic viral hepatitis and alcoholic liver disease. There is a high disease burden and mortality globally, especially in sub-Saharan African (SSA) countries such as Ghana, where the primary cause of HCC and cirrhosis is infection with hepatitis B virus (HBV).

Researchers at Karolinska Institutet in Sweden have developed a tiny sensor for detecting pesticides on fruit in just a few minutes. The technique, described as a proof-of-concept in a paper in the journal Advanced Science, uses flame-sprayed nanoparticles made from silver to increase the signal of chemicals. While still at an early stage, the researchers hope these nano-sensors could help uncover food pesticides before consumption.

The majority of cold wave related deaths occurred in middle-income countries followed by high-income countries, deaths were likely to occur during heat waves than cold waves or severe winter weather, in particularly in high-income countries and increased CO2 emissions can result in an increased number of deaths during severe weather events. That is the conclusion of a recently published study that looked at extreme weather events and deaths in the years 1999 to 2018.

The repurposing of FDA-approved drugs for alternative diseases is a faster way of bringing new treatments into the clinic.

Their foundational observation set the stage for over three decades of sustained exploration of immunity and inflammation in atherosclerosis. This field has burgeoned, matured, and has reached the stage of clinical translation.

The nervous system is known to communicate with the immune system and regulate inflammation in the body. Researchers at Karolinska Institutet now show how electrical activation of a specific nerve can promote healing in acute inflammation. The finding, which is published in the journal PNAS, opens new ways to accelerate resolution of inflammation.

5-alpha-reductase inhibitors (5-ARIs), Finasteride and Dutasteride, are commonly used to treat lower urinary symptoms in older men with benign prostate hyperplasia. There has long been concern that these drugs may increase the risk of more aggressive forms of prostate cancer. In a new study recently published in JAMA Oncology, researchers at Karolinska Institutet found no increased risk of dying from prostate cancer for men treated with the drugs and lower risk with longer treatment duration.

KI is now looking for two students who want to work during the day and support our participation in the parade.

A mobile app that shows a child's weight development in real-time for children with obesity provides greater weight loss compared to conventional care. The fact that both families and healthcare professionals can follow the same data facilitates individualised extra support when needed. This is shown by a study from Karolinska Institutet published in the International Journal of Obesity.

Researchers at Uppsala University and Karolinska Institutet are one step closer to explaining why COVID-19 patients have a substantially increased risk of blood clots. The study, published in Nature Immunology, shows that a gene variant in the innate immune system influences the risk for blood clots in the lungs of severely ill COVID-19 patients.

Microscopic colitis is the most recently recognized inflammatory condition of the large intestine in which abnormal reactions of the immune system cause inflammation of the inner lining of the colon. At present, more than 10,000 people in Sweden are estimated to be living with the disease. Previously, insufficient awareness and knowledge of microscopic colitis have led to underdiagnosis of the disorder, leaving patients untreated.
