A person's biological age, in other words, the real age of their body, which is independent of chronological age and which can be measured in specific blood tests, is conditioned by their lifestyle habits. A study by the Neurovascular Research Group at the Hospital del Mar Medical Research Institute, published in the journal Biology, has for the first time associated a higher biological age with the presence of an indicator of brain ageing, white matter hyperintensities, areas of the brain that blood has a harder time reaching. Lifestyle habits influence the DNA configuration and determine biological age. If these habits are modified, DNA ageing and, therefore, biological ageing can be slowed down, thereby decelerating the increase in white matter hyperintensities in brain tissue.

The study, led by Dr. Xavier Nogués, has received one of the two biomedical research grants awarded by this organization, with a total endowment of 650,000 euros. The award ceremony took place in Madrid on December 14. A project to identify the factors that affect the risk of developing a state of fragility, headed by Dr. Xavier Nogués, director of the Clinical Translational Research Program at the Hospital del Mar Medical Research Institute and head of the Internal Medicine Department at the Hospital del Mar, has received one of the two grants for biomedical research awarded by the Francisco Soria Melguizo Foundation. These grants total 650,000 euros and were awarded on December 14 at a ceremony held at the Royal National Academy of Pharmacy in Madrid.

An international collaborative study involving the Hospital del Mar Medical Research Institute and the Hospital del Mar has analyzed data from over 200,000 stroke patients and more than two million control individuals from five different ancestries. This study has associated 89 genes, of which 69 were previously unknown, with stroke and its subtypes. The research provides crucial insights to guide future biological investigations into the processes leading to this condition. Additionally, it reveals that some of these genes could potentially serve as targets for drugs to prevent or treat this disease. It also offers genetic prediction tools, improved and validated for the first time in non-European populations, to guide the development of new drugs.

A study by the Hospital del Mar Medical Research Institute and Pompeu Fabra University has found that not all HIV patients respond adequately to the SARS-CoV-2 vaccine. The work has been published in the journal Frontiers in Immunology. Up to 20% of people with HIV being treated with antiretroviral drugs do not regain normal levels of immune cells in their blood. These people, with a depressed immune system, are considered to be at risk of SARS-CoV-2 infection and were prioritised in the COVID-19 vaccination strategy, just as other at-risk groups were. However, until now it was not known how they responded to immunisation with RNA-based vaccines, such as those from Pfizer and BioNTech.

Patients admitted due to SARS-CoV-2 infection with imbalanced levels of two immune system cells, CD4 and CD8 T lymphocytes, have a worse prognosis and a higher risk of death. Having more than twice the number of CD4 lymphocytes than CD8 lymphocytes increases the probability of dying from the infection by 4.6 times and the chances of experiencing respiratory distress by two times, according to a study by physicians and researchers from Hospital del Mar, the Hospital del Mar Medical Research Institute, Universitat Pompeu Fabra, and CIBERINFEC, published in the journal Frontiers in Medicine. This finding leads the study's authors to recommend a more aggressive therapeutic approach for these patients from the moment of admission. Additionally, they believe that this situation may be repeated in other viral infections.

A study by cardiologists at Hospital del Mar and researchers at the Hospital del Mar Medical Research Institute reveals that more than half of the people treated for the arrhythmia known as atrial flutter will suffer an episode of atrial fibrillation in less than a year. The risk of atrial fibrillation reaches 86% in those patients who score higher on a risk scale designed by the team, prompting the need for more accurate monitoring of these patients because of the likelihood that they could suffer other cardiovascular problems, such as a stroke. The study, published in the Journal of Cardiology, was funded by the 2014 La Marató de TV3, dedicated to heart disease.

The possibility of re-freezing vials once they are prepared may enable the manipulation of vaccines in the country of origin, freezing the syringes, and sending them to their destination for immediate use, without the need for a major infrastructure. The shelf life of the re-frozen vaccine is at least one month.

A study on the vaccine response of patients with primary antibody deficiency carried out by the Functional Unit of Primary Immunodeficiencies at Hospital del Mar together with the dibi Network (Reference Laboratory of Catalonia) has revealed that a good number of these people have antibodies against SARS-CoV-2 without actually having contracted COVID-19. The study, published in the journal Immunology, is the first to certify the transmission of antinucleocapsid antibodies (ANC) from donors to patients with primary immunodeficiency.

The hospital is the only healthcare centre in Spain to form part of the group behind the project, which aims to create a mobile app platform to personalise patient monitoring for sufferers of this disease. The initiative will receive funding from the EU's HORIZON programme. Hospital del Mar's Pneumology Department is part of the TOLIFE project (Artificial Intelligence and Smart sensing TOward better management and improved quality of LIFE in chronic obstructive pulmonary disease). This is an international initiative to develop a tool that, using artificial intelligence, will improve and personalise the treatment of patients with chronic obstructive pulmonary disease (COPD).

A study by doctors and researchers at Hospital del Mar and the Hospital del Mar Medical Research Institute confirms that COVID-19 infection is much more virulent than the flu in this group of patients, despite the fact that they are younger and in better health. They also require longer hospital stays and more care. This means that the price of their treatment is double that of patients admitted for influenza, with an extra cost of almost 10,000 euros. The study has been published in the journal Clinical Infectious Diseases and presented at the European Congress of Microbiology and Infectious Diseases held in Lisbon.
