Immigrants develop their first psychotic episode earlier than native-born individuals-on average, three years earlier. According to the study, this is linked to accumulated trauma throughout life and the age at which migration begins. The research, conducted at Hospital del Mar in collaboration with the Hospital del Mar Research Institute and CIBERSAM, appears in the European Journal of Psychotraumatology.

Young people beginning university show a much higher prevalence of suicidal thoughts and attempts compared to the general population, according to an international study led by the Hospital del Mar Research Institute. The study, part of the World Mental Health International College Student Initiative led by Harvard University, invited nearly 73,000 students from 71 universities in eighteen countries to participate. It is the most comprehensive study conducted to date on this population. Experiencing traumatic events during childhood and having parents with mental health disorders are the main risk factors for suicidal behavior. In addition, transgender students are 2.4 times more likely to experience suicidal thoughts than other students.

A study published in Science identifies the complementary role of the main families of neurons in representing the environment. The work, coordinated by Dr. Manuel Valero, head of the Neural Computation Laboratory at the Hospital del Mar Research Institute, presents an open-access tool to analyze neuronal diversity. The tool is already freely available and can be applied to the study of other brain regions and of diseases such as Alzheimer's, epilepsy, major depression, and Down syndrome, paving the way for more specific therapeutic strategies.

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.
