Research led by CIBER-ISCIII, within the framework of the PREDIMED-Plus study, describes how a low-calorie Mediterranean diet combined with physical exercise reduces the risk of diabetes, confirming the joint benefit of both lifestyle approaches in preventing this disease. The study received over 15 million euros in funding, mainly from the ISCIII and the CIBER Consortium, and involved three CIBER research areas and more than 200 specialists from 23 research centers, including the Hospital del Mar Research Institute.

On Thursday 14 August, Dr Joaquín Arribas, Director of the Hospital del Mar Research Institute (HMRIB), and Dr Vanesa Nogales, its General Manager, visited the Josep Carreras Leukaemia Research Institute. They were received by the new Director of the IJC, Dr Ari Melnick, the incoming Managing Director, Cristina Casaus, and accompanied by Dr Anna Bigas, Principal Investigator of the Stem cells and cancer group, who is affiliated with both institutions. The institutional meeting provided an opportunity to share strategic challenges as well as to identify and explore new areas of collaboration. Within this framework, the leadership of both centres formalised the agreement regarding the cell culture room at the HMRIB facilities. This initiative, promoted by the IJC and the Josep Carreras Foundation, provides researchers with a state-of-the-art infrastructure to carry out their research.

According to a study by the Karolinska Institute in Sweden, co-led by David Abbad-Gómez, researcher in the Epidemiology and Evaluation Research Group at the Hospital del Mar Research Institute and a member of the RICAPPS research network on chronicity, primary care and health promotion (part of the Carlos III Health Institute), people who follow a balanced diet have between 9% and 19% fewer chronic diseases after 15 years.

70% of Chronic Obstructive Pulmonary Disease (COPD) cases go undiagnosed. Now, a study led by Hospital del Mar and the Hospital del Mar Research Institute has validated ten metabolites that are altered in patients with this disease. These metabolites can be identified through a simple blood test, which opens the door to their use in future population-based screening for suspected COPD. The study used artificial intelligence tools to determine which of these molecules yielded the most accurate results.

This is indicated by the results of the PENSA study, a clinical trial conducted jointly by the Research Institute of Hospital del Mar and the Barcelonaβeta Brain Research Center, the research center of the Pasqual Maragall Foundation. The study concludes that combining a healthy lifestyle program with epigallocatechin gallate (EGCG), a natural compound found in green tea, could offer sustained cognitive benefits in people at high risk of developing Alzheimer's disease. Over the course of one year, around one hundred cognitively healthy volunteers, but in stages potentially prior to the onset of dementia, were monitored. They were divided into three groups. One group received only healthy lifestyle advice. The other two groups underwent a lifestyle improvement intervention program combined with either EGCG or placebo.

One of the symptoms associated with long COVID is chronic fatigue. Until now, its origin was unclear. A study conducted by the Pneumology, Pathology, and Intensive Care Services at Hospital del Mar, along with researchers from the Hospital del Mar Research Institute, points to a potential cause: fibrosis in the walls of blood vessels triggered by the infection. The study has been published in the journal Ultrastructural Pathology. The research is based on muscle biopsies taken from the quadriceps of 35 patients admitted to Hospital del Mar during the pandemic. Eight of these samples were analyzed using electron microscopy to assess the state of the tissue. Significant fibrosis was found in the walls of the capillaries supplying blood to the muscle fibers, a finding consistent with observations in other organs from patients who died from COVID-19.

Researchers from the Hospital del Mar Research Institute and Yale University, in the United States, have demonstrated how the action of certain genes on precursor cells of brain formation can cause alterations linked to cortical malformations but also to the origin of neuropsychiatric diseases such as autism or bipolar disorder. The study, published in Nature Communications, is the first of its kind. It has been able to simulate the function of a list of nearly 3,000 genes linked to these pathologies during human brain development.

The project aims to determine the prognostic value of molecules in the tumor microenvironment in melanoma. A project led by Dr. Sònia Segura, attending physician in the Dermatology Department at Hospital del Mar and researcher in the Dermatological Inflammatory and Neoplastic Diseases Research Group at the Hospital del Mar Research Institute, has received one of the Jané Mateu Foundation grants in its third edition. The award ceremony took place on June 25 at the modernist site of Hospital de Sant Pau. The study aims to determine the prognostic value of molecules in the tumor microenvironment in melanoma, specifically a marker related to activation of the TGF-beta pathway, which is associated with the disease's ability to evade the immune system.

These molecules act as small building blocks that regulate the cellular response by switching certain internal signals on or off. This is the conclusion of an international study led by the Hospital del Mar Research Institute, published in the journal Nature Communications. The findings may help develop more precise drugs to treat various diseases more effectively, while avoiding side effects.

The first collaboration day between the Hospital del Mar Research Institute and the Institute for Bioengineering of Catalonia (IBEC) was held today at the Barcelona Biomedical Research Park (PRBB). The meeting provided an opportunity to share research projects, identify areas for collaboration and formalise a strategic alliance through the signing of a collaboration agreement between the Hospital del Mar and the Hospital del Mar Research Institute and IBEC.
