Fri, 13 Jan 2023 14:03:55 +0100 https://news.ki.se/improved-reliability-of-epigenetic-clocks Epigenetic clocks based on DNA methylation data are widely used aging biomarkers useful to assess biological age in population-based cohorts. However, their utility has been limited by technical noise. In this paper, we present a method that produces high-reliability clocks for applications such as longitudinal studies and intervention trials. Wed, 17 Aug 2022 09:22:02 +0200 https://news.ki.se/early-accumulation-of-tau-in-the-brain-predicts-memory-decline-in-alzheimers-disease Researchers at Karolinska Institutet have compared how well different Alzheimer’s biomarkers predict the progression of the disease and its effect on the memory. They found that early accumulation of tau proteins in the brain as measured by PET scanner was more effective at predicting memory impairment than biomarkers in the cerebrospinal fluid or amyloid plaque in the brain. The results are published in the journal Molecular Psychiatry. Fri, 01 Oct 2021 02:00:05 +0200 https://news.ki.se/new-biomarkers-for-life-threatening-soft-tissue-infections Rapid diagnosis is crucial in bacterial soft tissue infections to reduce the risk of severe injury or amputation. Vague symptoms and a heterogeneous patient group increase the risk of misdiagnosis. Researchers at Karolinska Institutet and other research institutions have now, with the help of AI, identified a new and very promising biomarker. The study, published in the Journal of Clinical Investigation, may have implications for both diagnosis and treatment. Thu, 15 Jul 2021 18:00:05 +0200 https://news.ki.se/new-marker-predicts-benefit-of-radiotherapy-for-early-stage-breast-cancer A study involving researchers at Karolinska Institutet and University of Gothenburg has found that low levels of a protein called PDGFRb are associated with particularly good results of radiotherapy in women with early-stage breast cancer. The study, which is published in the journal Clinical Cancer Research, also suggests that the efficacy of radiotherapy can be improved with drugs that block this protein.

Now, researchers at Karolinska Institutet and KTH Royal Institute of Technology, among others, have examined a type of cell in the brain blood vessels that could explain the unpredictable disease origins and dynamics. The results indicate a hitherto unknown connection between the nervous and vascular systems. The study, published in Nature Medicine, has potential implications for earlier diagnoses and future treatments.

However, according to a new paper co-authored by researchers at Karolinska Institutet and published in the journal Circulation, the anti-inflammatory properties of HDLs could be an even better biomarker for future cardiovascular events. Mon, 12 Apr 2021 11:00:55 +0200 https://news.ki.se/genetic-differences-important-for-alzheimers-diagnosis The two used methods for detecting amyloid pathology in Alzheimer's disease give ambiguous results, with the risk of incorrect or delayed care interventions. Now, researchers at Karolinska Institutet have found genetic explanations for the differences. The study is published in Molecular Psychiatry and may be important for more individual diagnostics and the development of future drugs. Fri, 11 Dec 2020 02:00:04 +0100 https://news.ki.se/mid-levels-of-immune-marker-at-birth-may-protect-against-autism Researchers at Karolinska Institutet have investigated the association between certain immune markers in neonates and the risk of later developing autism spectrum disorder (ASD). They found that mid-levels of a classical marker of inflammation, C-reactive protein, were associated with the lowest risk for ASD – whereas too much or not enough were linked to increased risk. The study is published in the scientific journal Biological Psychiatry.

Variations within the gene that encodes the CYP2C19 enzyme results in extreme differences in the levels of escitalopram achieved in patients, according to a new study published in The American Journal of Psychiatry. Prescribing the dose of escitalopram based on a patient’s specific genetic constitution would greatly improve therapeutic outcomes.
