A new doctoral thesis from Karolinska Institutet shows that the health outcomes of children conceived with assisted reproductive technology (ART) are generally reassuring, although certain combinations of specific methods were found to be linked to a slightly increased risk of rare conditions. The findings alleviate concerns about the safety of ART and can support better counseling as well as informed decision making among patients and clinicians.

Each year, more than 6,000 Swedes are diagnosed with melanoma. Melanoma is a form of skin cancer that, if detected late, can be fatal. Not all melanomas behave in the same way. A new doctoral thesis from Karolinska Institutet investigates why some patients have poorer outcomes than others and whether certain markers in tumor tissue can help us predict who is at risk.

By combining multiple types of analysis, researchers can better understand why treatments work differently in acute myeloid leukaemia (AML). This is shown in a new doctoral thesis from Karolinska Institutet.

Melanoma is the most aggressive form of skin cancer and can be difficult to treat in advanced stages. In a new doctoral thesis from Karolinska Institutet, Ellen Heurlin shows that radiotherapy combined with modern drug treatments provides clear clinical benefit in advanced melanoma. The results demonstrate good local tumor control, especially with stereotactic techniques, and few serious side effects. The most promising results were observed when radiotherapy was combined with immunotherapy.

Texts for cognitive behavioural therapy (CBT) that were culturally adapted using AI were perceived as equally relevant and acceptable as texts adapted by a psychologist. The findings, published in JMIR Formative Research, suggest that AI could help make evidence-based psychological treatments more accessible to refugees and migrants.

Many common diseases and other complex traits, such as heart disease, diabetes, and psychiatric disorders, are influenced by a very large number of genetic variants, each with only a small effect. They are also shaped by environmental and lifestyle factors, which makes their causes highly complex. By analyzing genetic data from very large groups of people across the whole genome, researchers can identify these small genetic signals and better understand how they contribute to health and disease.

Genetic markers may be the key to more precise surveillance programs for individuals with the hereditary cancer syndrome Li-Fraumeni. In a new doctoral thesis from Karolinska Institutet, Alexander Sun Zhang shows how tailored follow-up strategies can reduce the burden on patients, particularly children. These findings have already influenced the Swedish national guidelines.

Many women with breast cancer receive endocrine therapy, also known as anti-hormonal therapy, to reduce the risk of the disease returning. However, for a significant group, the treatment does not work as intended. A new doctoral thesis from Karolinska Institutet maps tumours from patients who have experienced a relapse in their disease despite ongoing endocrine therapy, to understand why the treatment fails and how these patients can be identified earlier.

An external review panel has assessed that doctoral education at Karolinska Institutet is characterised by ambition and academic excellence. The external review was initiated by the Committee for Doctoral Education.

Attention deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental condition that affects how the brain develops and functions. It’s usually noticed in childhood, and more than half of those diagnosed keep experiencing symptoms as adults. Medicines for ADHD can reduce these symptoms, but lasting benefits depend on continuing the medication regularly.

The call will open on 23 February 2026 and close on 23 March 2026 at 14:00. Apply via Prisma.

Breast cancer tumours can contain different cell types and structures, which may influence how the disease develops and responds to treatment. In a new thesis from Karolinska Institutet, Qiao Yang at the department of oncology pathology uses computer based methods and multi omics data to map this variation in large, untreated breast tumours. The findings may help support more comprehensive diagnostic strategies and inform future treatment decisions.

Cancer is complex and hard to treat, with many forms that change over time. This makes treatment complicated: a drug may help one patient but not another. Developing new cancer drugs is also slow and costly, often taking years and failing before reaching patients. This thesis explores how advanced laboratory models and artificial intelligence could make the process faster.

Breast cancer ecotypes represent unique combinations of three key factors: the internal states of tumor cells, the local tumor microenvironment, and the overall immune response. Together, these elements reflects the complex interaction between the patient, the tumor, and the treatment.

Depression is one of the most common mental health conditions, and some people recover with medications or therapies. However, for some individuals, treatment does not work, even after several attempts. This harder-to-treat form of depression is known as treatment-resistant depression (TRD). People affected by TRD often experience more severe and long-lasting symptoms, lower quality of life, and more physical health problems than other depression cases without TRD.

In a significant step for European collaboration in neuroscience and technological innovation, the Medical University of Innsbruck (MUI) has officially joined The European University of Brain and Technology – NeurotechEU.
