According to a new doctoral thesis from Karolinska Institutet, misinformation about infectious diseases can be debunked most effectively by first stating the false information and then correcting it with the correct information. All studies in the thesis about risk communication and misinformation in infectious disease outbreaks were conducted in Sierra Leone, focusing on Ebola, Typhoid and Malaria.

The Charlson co-morbidity index (CCI) is a disease index that was originally created to predict short-term mortality but is increasingly used as a proxy for comorbidity burden, and is often used as a co-variate, for instance in regression models. There are currently several available versions of the CCI. The existence of multiple morbidity indices creates confusion, increases the risk of mistakes and requires individual researchers to spend considerable time examining included codes.

The ability of our skin to protect us from chemicals is something we inherit. Some people are less well-protected which could imply an increased risk of being afflicted by skin disease or cancer. A new study from Karolinska Institutet that has been published in Environmental Health Perspectives shows how the rate of uptake of common chemicals is faster in people with a genetically weakened skin barrier.

According to the researchers, the nanobodies have the potential to be developed into a treatment for COVID-19.

The main causes of death were malaria and anemia. The study is to this date the largest study conducted on cerebral palsy in Africa and was published in PLoS One.

In countries with a severe shortage of surgeons it is common for some operations to be carried out by medical staff with lower formal qualifications. Researchers at Karolinska Institutet have led an international study on the safety and efficacy of a common surgical procedure. The study, published in JAMA Network Open, shows that inguinal hernia operations performed by associate clinicians at a hospital in Sierra Leone were just as safe and effective as those performed by doctors.

Small studies have suggested that a group of medications called RAS inhibitors may be harmful in persons with advanced chronic kidney disease, and physicians therefore often stop the treatment in such patients. Researchers at Karolinska Institutet now show that although stopping the treatment is linked to a lower risk of requiring dialysis, it is also linked to a higher risk of cardiovascular events and death. The results are published in The Journal of the American Society of Nephrology.

The results are published in the journal Nature.

Marie Holmqvist, associate professor at the Clinical Epidemiology Division at the Department of Medicine Solna, are one of two who has been appointed Wallenberg Clinical Fellows 2020 award for her research project “Cancer in systemic rheumatic disease – occurrence, genetics, prediction and consequences”. The project studies why cancer is more common in patients with systemic rheumatic diseases and how we can predict which patients will develop cancer earlier, so we can intervene.

During the spring pandemic, the higher education sector, including Karolinska Institutet, received a temporary permit from the government to analyse covid-19 tests in connection with the increase in the spread of the infection. The number of analyses carried out increased rapidly, but now other operators have started up, which means that KI can go back to its regular laboratory activities. KI however still remains in a state of a preparedness to reorganize its operations should the need arise.
