Antibiotic resistance
Resistant bacteria took her daughter's life
Pernilla Rönnholm lost her daughter because of antibiotic resistant intestinal bacteria. Now she works for preventing more children to being affected.
She will strengthen the international work against resistance
KI alumni Malin Grape has been appointed by the government as AMR ambassador to work against antimicrobial resistance.
Why antibiotics are overused in dentistry
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.
Gel fights drug-resistant bacteria and induces body’s natural immune defense
Researchers from Karolinska Institutet, Karolinska University Hospital and KTH Royal Institute of Technology have developed a new kind of antibiotic-free protection for wounds that kills drug-resistant bacteria and induces the body’s own immune responses to fight infections. The technology is described in the Journal of the American Chemical Society and could be an important tool in the fight against multidrug-resistant bacteria.

Gene variant influences blood clot risk in severe covid-19
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.
mRNA booster vaccines may be a good investment in resource-poor countries
Vaccines based on inactivated SARS-CoV-2 virus are commonly used in resource-poor countries due to their low cost. New research from Karolinska Institutet shows that a booster shot of mRNA vaccine to individuals who have received two doses of inactivated vaccine offers the same level of protection against COVID-19 as three doses of mRNA vaccine. The findings are published in the journal Nature Communications.
Air pollution linked to higher risk of COVID-19 in young adults
Residential exposure to ambient air pollutants is linked to an elevated risk of SARS-CoV-2 infection, an observational study of young adults in Stockholm shows. The study was conducted by researchers from Karolinska Institutet and is published in JAMA Network Open.
No increase in pregnancy complications after COVID-19 vaccination
Vaccination against COVID-19 during pregnancy is not associated with a higher risk of pregnancy complications, according to a large-scale registry study from Karolinska Institutet in Sweden and the Norwegian Institute of Public Health published in the journal JAMA.
