A recent study from the Hospital del Mar Research Institute shows that cannabis use is associated with increased brain inflammation, which may affect the therapeutic effectiveness of antipsychotic treatments. The study analysed brain MRI scans from nearly 100 individuals-patients with first-episode psychosis and healthy volunteers-using a novel technique that measures extracellular free water. This is the first study to apply this method to examine the effects of cannabis use in psychosis. The findings are published in Molecular Psychiatry and reinforce recommendations against cannabis use in people with psychotic disorders.

Infections caused by Enterobacterales, Pseudomonas aeruginosa and Acinetobacter baumannii are identified as priorities for clinical research. The study, published in the Journal of Infection and Public Health, involved 60 experts who reached consensus on the main priorities for the development of new clinical trials. The work carried out within the MePRAM project of CIBER has resulted in several priority lists-microorganisms, clinical syndromes, patient populations and anti-infective treatments-aimed at guiding future research from a personalised medicine approach.

A research team from the Parc Taulí Research and Innovation Institute (I3PT), in collaboration with the Pere Virgili Health Research Institute (IISPV) and the Hospital del Mar Research Institute (HMRIB), has identified a clear association between the accumulation of abdominal fat and premature vascular aging in people with type 1 diabetes who have no previous history of cardiovascular disease. The research was based on a cohort of 179 individuals with this condition, all of whom were assessed at Parc Taulí University Hospital. Despite having good control of blood glucose levels, blood pressure, and lipid profile, approximately 10% of the individuals studied showed signs of premature vascular aging-a key factor in the development of cardiovascular and microvascular complications that directly affect quality of life and life expectancy.

The Hospital del Mar Research Institute Barcelona (HMRIB) hosted last Wednesday the 28th the inaugural session of the MAR Tech Transfer Academy, a new training programme designed to bring biomedical research closer to the market and to strengthen knowledge transfer and valorisation capabilities. The programme will count with three pillars: experience through a series of interactive sessions, curated tools that will be offered to the researchers and clinicians to help them during the transfer process and expert accompaniment, trough valorisation services.

The Machine of Forgetting is a guide to understanding how memory works and how it defines who we are. Through eleven questions, it explores a wide range of issues, from how we store memories to what makes us human, including the possibility that androids might have feelings. Published by Editorial Ariel, the new book by Dr. Rodrigo Quian Quiroga, neuroscientist at the Hospital del Mar Research Institute and ICREA professor, opens the door to the latest advances in neuroscience and artificial intelligence research, while also establishing parallels with art, philosophy, and football.

The Hospital del Mar Research Institute is participating in two of the projects selected by Barcelona City Council and the "la Caixa" Foundation as part of the 2025 edition of the grants awarded by the two entities to emerging research projects in the fields of health and sustainability. Altogether, the initiatives will receive a total of two million euros in funding. One of the projects (DESODEM-BCN) will analyse social determinants in urban dementia. It will study how socioeconomic position, social infrastructure and air pollution influence dementia symptomatology and biology in Barcelona. The project combines biomedical, social and urban research to identify inequalities in diagnosis and disease progression, with special attention to the pTau217 biomarker. It is led by the August Pi i Sunyer Biomedical Research Institute (IDIBAPS), in collaboration with the Hospital del Mar Research Institute, the Barcelona Urban Research Institute (IDRA) and the Barcelona Public Health Agency (ASPB).

Deaths among patients with acute myocardial infarction before reaching hospital were reduced, during the response by the Medical Emergency System of Catalonia (SEM), by 20% during this period, compared with what would have been expected in the period prior to the implementation of this initiative. Overall, 28-day mortality after suffering a heart attack decreased significantly, falling from 27% of cases to 19%. These findings are highlighted in a study by researchers from the Hospital del Mar Research Institute, in collaboration with Hospital de Sant Pau and Hospital Clínic de Barcelona, which analysed data from 100,000 people who suffered a heart attack in Catalonia between 2008 and 2019.

Researchers from the Hospital del Mar Research Institute and the Vall d'Hebron Institute of Oncology have demonstrated, in animal models, the role played by these cells in the development of cancer cells. The study, published in Science Advances, shows that eliminating these cells at an early stage of tumor growth promotes tumor proliferation and the formation of metastases. By contrast, combining their elimination with an inhibitor of the CCL2 molecule reduces tumor size and eliminates metastases.

The journal Nature Mental Health has published a landmark scientific article on the prevention of depression and suicidal behaviour through an evidence-based programme designed to reduce depression and suicidal behaviour: the 4-Level Community Intervention, developed by the European Alliance Against Depression (EAAD). The EAAD approach offers a sustainable model of community-based mental health care that can be effectively adapted to a wide range of contexts, including current and future public health emergencies.

A clinical trial led by a team from the Hospital del Mar Research Institute, in collaboration with Hospital de la Santa Creu i Sant Pau, has received nearly €1.3 million in funding from Spain's Carlos III Health Institute (ISCIII), under the 2025 call of the Strategic Action in Health-Strategic Lines of Health Research. It is one of the 14 clinical trials selected. The trial is led by Dr. Ana Aldea, coordinator of the HMRIB Clinical Research Unit and Head of the Clinical Pharmacology Section at Hospital del Mar, and Dr. Rafael de la Torre, coordinator of the Integrated Pharmacology and Systems Neuroscience Research Group at the Hospital del Mar Research Institute.
