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.

We know that lifestyle affects health. But even factors that you cannot control have an influence. Here are six examples.

Research on new methods of treating weapon-related injuries is being conducted at Karolinska Institutet in collaboration with the Swedish Armed Forces and NATO. The goal: To reduce the risk of serious injury and death.

Having a baby at an early age is fraught with risk. Advice from other teenagers can be one way of increasing the use of contraceptives amongst refugee girls in Uganda.

Patient-initiated brief admission as a complement to outpatient psychiatric care is appreciated by nurses and patients, and can reduce levels of anxiety in people with emotional instability and self-harm, a new thesis from Karolinska Institutet reports.

One of KI’s largest international collaborations is with Makerere University in Uganda. In time for Makerere’s 100th anniversary, the partnership is to manifest itself in a Centre of Excellence for Sustainable Health. A delegation from KI travelled in May to Uganda to cement the relationship.

Cannabis use is associated with an increased risk of other illicit drug use as well as of anxiety and depression – at least among those who have used cannabis during the 2000s, according to a new doctoral thesis from Karolinska Institutet. The results also show that cannabis-related diagnoses have gradually increased, especially in young adults and more commonly in men with less education, lower incomes and other psychiatric diseases.

Millions of Ukrainian children have been displaced, either internally or as refugees, by the war with Russia. A systematic review by researchers at Karolinska Institutet and Ukraine’s Sumy State University has compiled the scientific literature on children’s health in Ukraine. The study, which is published in the journal Acta Paediatrica, could prove useful for clinicians treating refugee children from Ukraine.

Children with migration backgrounds in Sweden are less likely than other children to receive recommended treatment for psychiatric diagnoses such as ADHD and depression, a paper from Karolinska Institutet published in the journal Epidemiology and Psychiatric Sciences reports.

The current pandemic shows how quickly health misinformation can spread. However, there are tools to debunk misinformation as demonstrated by a new study on health communication strategies from Karolinska Institutet, published in the journal BMJ Global Health. The study, which focuses on misinformation about typhoid in Sierra Leone, also shows that explicitly addressing falsehoods seems more effective in busting misbeliefs than simply stating scientific facts.

Implementation of WHO’s recommended public health policies on alcohol, unhealthy foods and tobacco has been slow globally, according to a study led by researchers at Karolinska Institutet and the London School of Hygiene & Tropical Medicine, published in the journal The Lancet Global Health. The study found particularly low implementation in poor, less democratic countries and where corporations had more influence for example through corruption and political favoritism.

Congratulations to Emilie Agardh who receives 4 920 000 SEK in project grant from Forte for the project A new approach to capture inequalities in health.

Research on the role of diet in the development of type 1 diabetes is generally of low evidence, but there are some high-quality studies indicating that longer breastfeeding and later introduction to gluten may reduce the risk of disease. That is according to a systematic review and meta-analysis of available research on foods that may be linked to the risk of developing the type 1 diabetes in childhood. The study by researchers at Karolinska Institutet is published in the journal EBioMedicine.

Critical illness results in millions of deaths globally every year, many of which could be avoided with basic, life-saving care. Now, a new study led by researchers at Karolinska Institutet outlines a baseline bundle of care interventions that global experts agree should be available for all critically ill patients. The study, published in the journal BMJ Global Health, provides a blueprint for hospitals on how to reduce preventable deaths, including from COVID-19.

The evolutionary ability to identify sick individuals is crucial to reducing contagion and thereby improving chances of survival. Although most animals have this ability, whether humans have the same behavioural immune system has long been a subject of discussion. Researchers at Karolinska Institutet have now proven that hunter-gatherer groups can, with great certainty, identify the sick from Western Europe. The study was published in Proceedings of the Royal Society B.

Studying the implementation of public health interventions typically involves the identification of “facilitators” and “barriers”. In the case of active tuberculosis case-finding (also referred to as community-based tuberculosis screening), many studies have documented facilitators and barriers, but only few have explored the “how-to” of capitalizing on facilitators and overcoming barriers to put active case-finding into practice. This new study contributes to filling this gap.

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.

More than 1,200 people with rare diseases have received a diagnosis thanks to the integration of large-scale genomics into the Stockholm region’s healthcare system. This is according to a study from Karolinska Institutet in Sweden that analysed the result of the first five years of collaboration on whole genome sequencing between Karolinska University Hospital and SciLifeLab. The work, published in Genome Medicine, constitutes a major leap forward in the emerging field of precision medicine.

The virtual SPARKS conference held on 2-3 December will gather a network of global leaders in public policy and research to facilitate the exchange of knowledge on social protection and health. Knut Lönnroth is the founder of the SPARKS Network and Professor of Social Medicine.

Thirteen researchers connected to Karolinska Institutet are on the 2020 list of highly cited researchers presented by Clarivate, the company behind Web of Science.

Active lifestyle choices such as eating vegetables, exercising and quitting smoking can reduce the risk of chronic kidney disease, a new study led by researchers at Karolinska Institutet in Sweden and Griffith University in Australia, reports. The study is published in the Journal of the American Society of Nephrology.

People with dementia disease receiving home care feel that they are not treated with the same degree of respect and dignity as people who do not have dementia and receive the same service. That is according to a study by researchers at Mälardalen University (MDH), Karolinska Institutet and Dalarna University, published in The Journal of the American Medical Directors Association (JAMDA).

Knowledge of how human fat tissue is affected by age has long been defined by numerous mouse-based studies. Researchers at Karolinska Institutet in Sweden have now, for the first time, been able to conduct a prospective study on humans that provides novel insights into how our fat cells reduce lipid metabolism with age. The study is published in the journal Cell Metabolism.

Migrants from Africa and the Middle East and their children are more likely to be placed under compulsory care than the Swedish-born population when admitted to hospital for psychosis for the first time. That is according to a large, nationwide study by researchers at Karolinska Institutet in Sweden and University College London in the U.K., published in the journal Psychological Medicine.

Patricia Eustachio Colombo, doctoral student with the Department of Global Public Health at KI, is first author of the cross-sectional study based on data from the Swedish national dietary survey “Riksmaten ungdom” published in Public Health Nutrition.

Children of parents suffering from mental illness have a higher risk of injuries than other children, according to a study by researchers at Karolinska Institutet in Sweden, published in the journal BMJ. The risk is elevated up to 17 years of age and peaks during the first year of life. The findings highlight the need for parents with mental illness to receive extra support around child injury prevention measures as well as early treatment of mental morbidity among expecting parents.

An extensive workshop has been held to further the vision of creating a Centre of Excellence for Sustainable Health. Karolinska Institutet is driving the development together with Makerere University in Uganda, with focus on non-communicable diseases and other high burden diseases.

Researchers worldwide are trying to develop a vaccine and antiviral treatments against the new corona virus spreading in China. At Karolinska Institutet, virus researchers Ali Mirazimi and Matti Sällberg are working to develop a prototype vaccine against the virus. But vaccine development takes time, and it will likely take at least six to nine months before an application for clinical studies can be filed and another two to three years before a vaccine could be ready for the public.

Babies born with low birth weights are more likely to have poor cardiorespiratory fitness later in life than their normal-weight peers. That is according to a study by researchers at Karolinska Institutet in Sweden published in the journal JAHA. The findings underscore the importance of prevention strategies to reduce low birth weights even among those carried to at term delivery.

When Nobel prize winner Michael Kremer initially looked at the data of his now famous 1990s Kenya school study, he felt shocked and disappointed. The data showed that more textbooks did nothing to improve educational outcomes, contrary to what most researchers believed. But rather than succumbing to disillusionment, Kremer dug deeper into Kenya’s schooling system to uncover what measures truly did make an impact and found his answer: targeted help for weak students.

Refugees and other migrants who move to Sweden are initially less likely to be diagnosed with alcohol or drug addiction than the native population but over time their rates of substance abuse begin to mirror that of the Swedish born population. That is according to a new study by researchers at UCL in the U.K. and Karolinska Institutet in Sweden published in the journal PLOS Medicine.

Children born to women who underwent gastric bypass surgery before becoming pregnant had a lower risk of major birth defects than children born to women who had severe obesity at the start of their pregnancy. That’s according to a matched cohort study by researchers at Karolinska Institutet and Örebro University published in the scientific journal JAMA. The findings indicate that weight-loss and improved blood sugar control could reduce the risk of major birth defects.

Refugees who fled to Sweden were no more likely to die by suicide than migrants who moved to the country on their own terms, according to a study by researchers at Karolinska Institutet in Sweden and UCL in the U.K. However, the risk of suicide for both groups increased the longer they stayed in Sweden and was after 20 years almost on par with that of the native population. The study is published in The British Journal of Psychiatry.

Two research projects at Karolinska Institutet have been awarded synergy grants from the European Research Council (ERC). In total, the researchers and their international partners were awarded about EUR 19 million (SEK 209 million) over a six-year period for studies that aim to widen our understanding of disease-causing fat cells and unlock new cancer treatments.

People with low scores on intelligence tests in adolescence run a higher risk of suicide and suicide attempt later in life. That is according to a study from Karolinska Institutet in Sweden that followed almost 50,000 Swedish men from the 1970s until recently. The study is published in the journal Psychological Medicine.

Correction: The article “Reduction in Mental Health Treatment Utilization Among Transgender Individuals After Gender-Affirming Surgeries: A Total Population Study,” published in The American Journal of Psychiatry on Oct. 4, 2019, has been corrected following a review of the statistical methodology and some of its conclusions.

The timing of anemia—a common condition in late pregnancy—can make a big difference for the developing fetus, according to research at Karolinska Institutet published in JAMA Psychiatry. The researchers found a link between early anemia and increased risk of autism, ADHD and intellectual disability in the child. Anemia discovered toward the end of pregnancy did not have the same correlation. The findings underscore the importance of early screening for iron status and nutritional counselling.

Stanford Medicine X has launched a new self-paced online course through Stanford online with faculty from Stanford University.

Many people struggle to keep their weight in check as they get older. Now new research at Karolinska Institutet has uncovered why that is: Lipid turnover in the fat tissue decreases during ageing and makes it easier to gain weight, even if we don’t eat more or exercise less than before. The study is published in the journal Nature Medicine.

PhD student Sara Causevic and researcher Helena Nordenstedt at the Department of Public Health Sciences and student Wiebke Mohr at the Department of Learning, Informatics, Management and Ethics started the Women in Global Health Sweden Chapter as a response to the Call to Action on Gender Equality.

Hello, Galit Andersson, who recently defended a doctoral thesis at the Department of Public Health Sciences, Karolinska Institutet. For your thesis you conducted large surveys of transgender people and people living with HIV in Sweden to assay their quality of life.

The research project is led by Ritva Rissanen, postdoc at the Department of Public Health Sciences, and will investigate sick leave patterns when returning to work after a work-related injury, among young adults.

Young people with lower school grades than their peers run a higher risk of mental ill-health and attempted suicide. In a new study published in the journal Acta Psychiatrica Scandinavica, researchers from Karolinska Institutet show that this risk persists into middle age.
