Team member Carina King with colleagues’ have an article published in this month’s issue of The Lancet Respiratory Medicine. The paper that is also featured on the cover, is about a multifacility, prospective, observational study conducted in rural Bangladesh to evaluate the potential effect of pulse oximetry implementation on the WHO IMCI-based outpatient care of 3848 young children with suspected pneumonia.

The podcast Riskzonen, featuring well-known KI staff members Mattis Öberg and Emma Frans, is back with a new season! The four episodes were released in May and June, and after a brief break over summer, more episodes will now be released each Monday, starting on 28 August. Each episode features the topic health crisis, in one way or another, ranging from relief efforts in war to antibiotic resistance. The new season is made in collaboration with the Centre for Health Crises.

Researchers at Karolinska Institutet have developed a molecular method able to detect whether or not bacteria respond to antibiotics within minutes. The findings are presented in the journal Nature Microbiology and the researchers now hope to develop a simple test for doctors to use.

Caregivers want patients to feel cared for. This, according to a new doctoral thesis from Karolinska Institutet, is one reason why they still give treatments that provide no benefit.

Antibiotic residues in wastewater and wastewater treatment plants in regions around China and India risk contributing to antibiotic resistance, and the drinking water may pose a threat to human health, according to an analysis from Karolinska Institutet published in The Lancet Planetary Health. The researchers also determined the relative contribution of various sources of antibiotic contamination in waterways, such as hospitals, municipals, livestock, and pharmaceutical manufacturing.

Patients who have indwelling urinary catheters often suffer from urinary tract infections, which can be difficult to treat. Now, researchers at Karolinska Institutet have discovered that the synthetic peptide CD4-PP has a good bactericidal effect against urinary tract bacteria, even those resistant to antibiotics. The study, published in the journal Cellular and Molecular Life Sciences, opens up for new possible treatment methods.

Sweden is one of the few countries that have removed the dental health recommendation to give prophylactic antibiotics to people at a higher risk of infection of the heart valves, so-called infective endocarditis. Since the recommendation was removed in 2012, there has been no increase in this disease, a registry study from Karolinska Institutet published in the journal Clinical Infectious Diseases shows.

Researchers at Karolinska Institutet, Umeå University, and the University of Bonn have identified a new group of molecules that have an antibacterial effect against many antibiotic-resistant bacteria. Since the properties of the molecules can easily be altered chemically, the hope is to develop new, effective antibiotics with few side effects. The findings have been published in the scientific journal PNAS.

Researchers from KTH Royal Institute of Technology, Karolinska Institutet and Karolinska University Hospital 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 presented in the Journal of the American Chemical Society and could be an important tool in the fight against multidrug-resistant bacteria.

MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers at Karolinska Institutet in Sweden are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results published in Advanced Materials Technologies show that the microneedle patch effectively reduces MRSA bacteria in the skin.

Hi there, Johanna Simin, PhD student in Clinical Epidemiology at the Centre for Translational Microbiome Research at Karolinska Institutet! You will defend your thesis entitled "The role of oestrogens and antibiotics on the development of cancer" on 1 June 2021. Can you tell us a little more?

Antibiotics use, particularly antibiotics with greater spectrum of microbial coverage, may be associated with an increased risk of new-onset inflammatory bowel disease (IBD) and its subtypes ulcerative colitis and Crohn’s disease. That is according to a study by researchers at Karolinska Institutet in Sweden and Harvard Medical School in the U.S., published in the journal The Lancet Gastroenterology & Hepatology. The association remained when patients were compared with their siblings.

Hi there Oliver Dyer, doctoral student at the Department of Global Public Health at Karolinska Institutet. On Thursday 12 March you will defend your thesis. Tell us, what is your thesis about?

Hi there Erika Saliba Gustafsson, doctoral student at the Department of Global Public Health at Karolinska Institutet. On Monday 2 March you will defend your thesis. Tell us, what is your thesis about?
