An international study in which researchers from the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau and the Universitat Autònoma de Barcelona (UAB) have participated has identified the mechanism by which patients with Fanconi anemia develop head and neck tumors and have been able to verify that it is the same mechanism that explains why smoking and drinking increase the risk of this type of cancer in the general population.

The results, published by the prestigious journal Nature, show that the deficiency in the cells’ natural process to repair the damage produced by chemicals that damage DNA, called aldehydes, is responsible for the risk of developing carcinoma of head and neck squamous cells.

Dr. Jordi Surrallés, head of DNA Repair Syndromes and Predisposition to Cancer research group and director of the Research Institute of the Hospital Santa Creu i Sant Pau – IIB Sant Pau and the Research Unit in Genomic Medicine Sant Pau- UAB and CIBERER researcher, is the only Spanish author of the study. He says that “these results help us understand the mechanisms involved in the origin of this type of tumor and allow us to look for new strategies aimed at trying to counteract this risk not only in patients with Fanconi anemia, but also in the population general where the combination of tobacco and alcohol also greatly increases the risk of suffering from these tumors”.

Aldehydes and DNA repair

Human cells are exposed to different aggressions from the environment that can cause DNA damage, so they need constant repair. In any cell at any given time, molecular processes are taking place to seal cracks in the double helix or correct the genetic code to maintain the proper functioning of the organism.

People born with Fanconi anemia -a rare disease characterized by genomic instability and a deficiency in DNA repair, resulting in chromosomal fragility- lack one of these repair systems functioning, which it makes its cells unable to eliminate the injuries created by different environmental factors.

These people may suffer from numerous medical problems throughout their lives, such as bone marrow failure, congenital malformations, and also a very high risk of developing head and neck tumors. “It is a type of cancer that is usually diagnosed at the age of 60-70 and in people with Fanconi anemia it can appear around the age of 20-30 and with an incidence that can be 700 times higher than in the general population”, explains Dr. Surrallés.

In this study, led by Dra. Agata Smogorzewska at the Rockefeller University in New York (United States), researchers have analyzed the genetic signatures of tumors from half a hundred patients with Fanconi anemia and have compared them with data from hundreds of sporadic tumors. They have thus been able to verify that the mutational signature is very similar in both types of tumors. Specifically, they have identified that cells cannot repair the damage caused by aldehydes in DNA, causing the mutations that will eventually cause cancer to accumulate.

A link with smoking and alcohol

One of the most important aspects that emerge from the results of this study is that drinking and smoking, which subject the body to aldehydes, promote the appearance of tumors by mechanisms similar to those involved in Fanconi anemia. “When the body is exposed to a greater amount of damage than the cells can repair, a process similar to that seen in people with Fanconi anemia occurs, and that’s when these tumors appear”, says Dr. Surrallés.

In other hand, Dra. Smogorzewska says these findings could also explain why head and neck tumors in patients with Fanconi anemia tend to be particularly deadly, with an average survival of just 17 months after diagnosis. “You have complete genomic havoc, simultaneously disrupting many different systems that normally prevent our cells from developing into cancer, and we think that’s one of the reasons for the aggressiveness of these tumors.”

With these results, new future challenges are raised, such as finding drugs that affect the repair mechanism of the damage caused by aldehydes, or manipulating the process to try not to accumulate this harmful substance in the body to try delay or prevent the appearance of these tumors both in patients with Fanconi anemia and in the general population. Dr. Surrallés explains that “we are already working in this direction by participating in two clinical trials”.

Patients with diabetes and previous macrovascular complications (coronary artery disease, cerebrovascular disease, or peripheral arterial disease) admitted for COVID-19 to a hospital have a worse prognosis and twice the mortality compared to the general population. This is described by an international study in which European research groups from France, the United Kingdom and Spain participate, led by the Diabetes and Associated Metabolic Diseases area of CIBER (CIBERDEM), the Research Group on Endocrinology, Diabetes and Nutrition of the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau, and the Endocrinology Service of the Hospital del Mar and which publishes the journal Cardiovascular Diabetology.

Diabetes, a risk factor

The COVID-19 pandemic has had a negative impact on people with diabetes. It is considered that diabetes poses a greater risk of presenting more serious forms of infection by the SARS-CoV2 virus, being associated with a higher rate of complications and mortality. However, the impact of having chronic complications associated with diabetes on the prognosis of COVID-19 was unknown to date.

Toward this end, this multicenter retrospective study collected cases from several cohorts and analyzed data from a total of 4,106 adults with preexisting diabetes hospitalized for COVID-19 infection in the United Kingdom, France, and Spain during the early phase of the pandemic. (between March 2020 and October 2020). Of these patients, a total of 1,652 (40.2%) had some previous macrovascular disease, with a death rate of 28.5%.

“This work is the first to demonstrate that the presence of macrovascular complications in patients with diabetes who are admitted for COVID-19 implies a worse prognosis and double the risk of mortality”, explains Dídac Mauricio, head of the CIBERDEM group at the IIB Sant Pau and coordinator of the study. “A subsequent analysis revealed that ischemic heart disease and cerebrovascular disease were the main contributors to these adverse results”, adds Gemma Llauradó, also a researcher in the study, assistant to the Endocrinology and Nutrition Service at the Hospital del Mar, researcher at IMIM-Hospital del Mar and CIBERDEM.

Along with these findings, the work has also shown that these patients had a lower proportion of ICU admissions and need for mechanical ventilation, possibly associated with selective admission criteria at this stage of the pandemic.

“Our findings in this research highlight the importance of correctly assessing the prognosis of these patients, as well as performing intensive follow-up in this high-risk subgroup. In addition, these results highlight the need to design specific public health programs aimed at preventing SARS-CoV2 infection in this population, which include for example, among other measures, strengthening vaccination campaigns”, the researchers conclude.

This research has been led by the head of the CIBERDEM group, Dídac Mauricio (Hospital de la Santa Creu i Sant Pau), in close collaboration with researcher Gemma Llauradó (Hospital del Mar), belonging to the CIBERDEM group led by Joan Vendrell. The publication of this work is the result of the collaboration between researchers from 3 European countries, England (Association of British Clinical Diabetologist – ABCD Diabetes), France (CORONAvirus SARS-CoV2 & Diabetes Outcomes -CORONADO- Study) and Spain (Hospital del Mar, Hospital de la Santa Creu i Sant Pau and HM Hospitals).

An international study in which researchers from the Dementia Neurobiology Group and the Memory Unit of the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau participated, leaded by Alberto Lleó, discovered two new genes associated with a significantly increased risk of developing Alzheimer’s disease.

The study, which has just been published in Nature Genetics, analyzes data from more than 32,000 complete genomes of Alzheimer’s disease patients and healthy controls. It’s the largest study of its kind in this pathology and that has been possible thanks to a collaborative effort by an international group led from the Amsterdam University Medical Centers, in the Netherlands; the Pasteur Institute in Lille and the University of Rouen Normandie, both in France, with the participation of the IIB Sant Pau as the only center in Spain.

The results of this work allow us to conclude that rare genetic variants in five genes: SORL1, ABCA7, TREM2, ATP8B4 and ABCA1, are associated with an increased risk of developing Alzheimer’s disease. “While this was already known for the first three genes, the finding that deleterious genetic alterations in ATP8B4 and ABCA1 can lead to Alzheimer’s disease had not been previously observed,” says Oriol Dols-Icardo, one of the authors of the study at IIB Sant Pau.

In addition, the researchers found that harmful mutations in a sixth gene, ADAM10, will most likely also lead to an increased risk of Alzheimer’s disease. However, the authors observed very few individuals with mutations in this gene, so this association will have to be confirmed by comparing an even larger population of Alzheimer’s disease patient genomes and healthy controls in order to classify ADAM10 as a “ Alzheimer’s gene”, explains Dols-Icardo.

Functions of these genes

All the genes identified in this study are involved in maintaining proper brain health, and deterioration of any of them is indicative of pathological processes associated with Alzheimer’s disease.

The previously discovered “Alzheimer’s genes”, which are SORL1, ABCA7 and TREM2, are involved in the processing of β-amyloid protein by neurons or in the brain’s immune system. Newly discovered genes go in this same direction. The ABCA1 gene maintains healthy cholesterol and phospholipid levels in brain cells and is associated with lower levels of amyloid aggregate protein, the accumulation of which in plaques is well known to be a hallmark of Alzheimer’s disease.

Like ABCA1, the (newly discovered) ATB8B4 gene is involved in phospholipid transport, primarily in immune cells in the brain. For its part, the ADAM10 gene plays a major role in the processing of the β-amyloid precursor protein, but in such a way that it prevents the formation of this protein. As explained by the IIB Sant Pau researcher, these identified genes, together, represent the molecular mechanisms that are most affected in Alzheimer’s patients, which helps to improve knowledge of the biological bases of the disease and puts on the table the possibility to investigate these genes as potential therapeutic targets.

It is estimated that between 60 and 80% of the risk of Alzheimer’s disease can be explained by genetic factors. In the case of early-onset disease (before age 65) this figure rises to more than 90%. Therefore, the single genome is postulated as a tool that could help to better stratify the risk of this disease in the future.

The research group in Neurobiology of Dementias of the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau, leaded by Dr. Juan Fortea, designed a detailed protocol for the enrichment of extracellular vesicles derived from astrocytes to from human plasma that will help improve the study of these cells and explore their role in the development of different neurodegenerative diseases.

Astrocytes have very important functions in various neurological processes, so the study of the content of extracellular vesicles derived from these cells could be an interesting platform for the discovery of biomarkers and the exploration of brain inflammatory pathways in a non-invasive way.

The principal investigator of this study, Natalia Valle, explains that the protocol was validated after a detailed analysis of the methods for isolating extracellular vesicles and contextualizing it in the field of neurology, specifically, astrocytes.

Extracellular vesicles are nanoparticles that are naturally secreted by all cells in the body. They contain many cellular components, such as genetic material, proteins, and lipid metabolites that often reflect the contents of their cell of origin. These cells participate in a wide range of functions by acting and transferring their contents to other cells under physiological and pathological conditions.

Given their small size, these vesicles are capable of diffusing into all biological fluids such as plasma and cerebrospinal fluid, from where they can be selected based on the specific surface markers they express, accurately reflecting the specific tissue environment from which they originate. Therefore, they represent an excellent non-invasive diagnostic tool, and can be considered a liquid biopsy for biomarker discovery. This trait is of special interest in neurology.

Currently, one of the main limitations for the use of these vesicles in research is that there is a lack of standardization of methodological protocols for their isolation. The IIB Sant Pau researchers present this new detailed protocol that consists of a first isolation of total extracellular vesicles by means of polymer precipitation, followed by a second step of immunoprecipitation of these vesicles.

A team of 6th year Medicine students from the Sant Pau Teaching Unit – UAB: Berta Rifà, Inés Clavero, Irene Rexach and Júlia de Mas, with the support of Dra. Marilina Santero, researcher at the Hospital de la Santa Creu i Sant Pau Research Institute and the Ibero-American Cochrane Center, won the hackathon organized by Xartec Salut.

A hackathon is a meeting of programmers with the aim of collaborative software development. On this occasion, it was about proposing a solution to current health challenges in the areas of rare diseases, mental health and childhood cancer.

The proposal of the Sant Pau group was the Burtoola tool, based on evidence and which connects clinical information and PROMs (patient reported outcomes) with the aim of reducing the prevalence of burnout among university students. The students beat the other 14 multidisciplinary groups that submitted and received recognition as part of the HealthTech 2030 Summit. The awards consist of the opportunity to participate in mentorships with potential sponsors to develop the project towards a test phase of concept.

The levels of the α-klotho protein could have a useful role as a biomarker to help identify patients with type 1 diabetes who are at increased risk of developing arteriosclerosis and thus increased cardiovascular risk. This is suggested by a study published in the journal Cardiovascular Diabetology, led by CIBERDEM researchers from the Endocrinology, Diabetes and Nutrition Research Group of the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau, directed by Dr. Dídac Mauricio, head of the Endocrinology Service of the same hospital.

Patients with diabetes have a higher risk of developing arteriosclerosis, especially those who also have kidney problems. Previous studies had already detected that these patients had altered levels of α-klotho. This protein is one of the main molecules involved in mineral metabolism, but until now its circulating levels had been found to be reduced in early stages of renal dysfunction, which had been associated with an increased risk of developing cardiovascular diseases.

“In people with diabetes, atherosclerosis is more frequent compared to the non-diabetic population. For this reason, it is very important to anticipate the development of atherosclerotic plaques subclinically, that is, when they have not yet caused symptoms”, explains Josep Julve, one of the main authors of the study at the IIB Sant Pau.

In this study, the researchers analyzed the relationship between circulating levels of different determinants of mineral metabolism related to calcium/phosphorus metabolism in relation to the burden of subclinical carotid arteriosclerosis in patients with type 1 diabetes. The results show that the proteins FGF23 and α-klotho present alterations associated with the progression of chronic kidney disease.

In this new investigation, unlike previous studies, the relationship between α-klotho levels in patients with type 1 diabetes without chronic kidney disease was analyzed. The results demonstrate, for the first time, that serum levels of this protein are increased in diabetics with subclinical arteriosclerotic disease. Furthermore, circulating levels of α-klotho were also related to the number of subclinical arteriosclerotic plaques in people without diabetes, postulating it as an independent risk factor and thus a potential biomarker.

The researcher comments that “one of the most relevant aspects of this study is that the association between high levels of α-klotho and the development of atherosclerotic plaque was observed in the absence of impaired renal function or established diabetic nephropathy.”

From these results, new research questions are derived that will give rise to new studies, both clinical and translational, to confirm the importance of this protein as an early risk factor for subclinical arteriosclerosis in patients with type 1 diabetes.

CIBERDEM researchers from the Endocrinology and Nutrition Service of the Hospital Universitario Arnau de Vilanova – Institut d’Investigació Biomédica de Lleida (IRB Lleida) and the Washington University School of Medicine, in Saint Louis, Missouri (United States) also collaborated in the development of this study. ).

The Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau participated, together with twenty research centers in Catalonia, in the II Gender Summit of the Health Research Centers of Catalonia, which promotes work in favor of progress towards more responsible health research.

The conference, chaired by the Minister of Health, Manel Balcells, and the Minister of Research and Universities, Joaquim Nadal, has been organized by the Health Quality and Assessment Agency of Catalonia (AQuAS) and the General Sub-Directorate of Research and Innovation of the Department of Health, in coordination with the Department of Research and Universities and iCERCA, and with the collaboration of the “la Caixa” Foundation. The event was attended by Maria Rosa Ballester, head of Research and Innovation in charge of IR Sant Pau and member of the organizing committee of this summit, and the director of IR Sant Pau, Dr. Jordi Surrallés.

The success of the second edition of the Summit is a firm step in the commitment signed by the health research centers in 2019, in order to contribute to the progression of women’s scientific careers, in the ‘elimination of barriers and implicit biases that affect health research.

In addition, with the aim of improving the quality of the knowledge produced for the benefit of the entire population, the commitment signed commits to incorporating the gender perspective in research and innovation. And although the gender gap still exists, the efforts of the centers have resulted in a slight improvement in the situation of inequality in teams and leadership.

Science Law, in terms of gender

During the course of the day, it was made clear that the future Catalonia’s Science Law, currently in the final stages of processing in Parliament, will establish a specific Catalan scientific policy defined, among other features, by the transversal incorporation of the gender perspective. The rule will promote the adoption of measures against gender bias and any other form of discrimination, and among its main objectives will set the promotion of parity between women and men in all areas of the knowledge system.

This law is also expected to integrate as organizing principles key points in gender matters such as the equality of women and men in the scientific career or the inclusion of the gender perspective in all phases of research, development and innovation .

Likewise, it foresees that public agents of research, development and innovation are equipped with a gender equality plan. This plan will need to incorporate measures to move towards gender equality, at the same time as including gender expert personnel in the evaluation and advisory bodies and ensure the balanced composition of the governing bodies. It will also be necessary to determine the evaluation tools for compliance with the plans, which will have to provide for the corresponding corrective measures.

The agents of the research, development and innovation system of the public sector must also include in the ethical codes the obligation to act in the event of sexual harassment and gender-based violence. In the same way, they will need to establish protection and support mechanisms for victims.

Hypatia’s engagement letter

The first edition of the Gender Summit took place in 2019 in Girona. Driven by the same objective, it hosted the creation of the Hypatia Practice Community and the signature, by the directors of the attending centers, of the Hypatia Charter of Alexandria. Among them, he signed IR Sant Pau. This agreement contained the twelve main points on which they focused their itinerary to reverse the situation of gender inequality shown by the nominal data.

This law integrates in its articles, therefore, the spirit of the commitments gathered from the Charter of Hypatia, focused on advancing towards gender equality in research and contributing to diversity in the world of science. The document focuses on specific aspects such as wage inequality, the elimination of obstacles that pose a problem for accessing a stable professional career after the doctorate, the improvement of employment contracts or the promotion of changes in organizational culture and the ‘professional structure.

Along these lines, the Hypatia Community, formed by the research centers in which AQuAS participates, has worked on various aspects to advance the Hypatia commitments. Recently, he has created and published the Tool to integrate the perspective of gender and sex, with the aim of guiding researchers when considering the incorporation of sex and/or gender in studies of basic science, clinical , health services and public health. The Tool contains a list of questions and sub-questions that address the integration of sex and gender in research, with specific aspects and examples of how to incorporate them in research.

The Community of Practice is also involved in the creation of an inclusive language guide for the world of research and in the Train the trainers program. This program is focused on training volunteer facilitators in unconscious bias so that they can provide training to people in their own institution.

In the area of research, the CERCA Institution, for its part, has since 2013 had a gender commission with representation from research centers, where initiatives in the field are coordinated and cases are exchanged ‘success. The activity has fundamentally focused on raising awareness and incorporating policies with a gender perspective in order to facilitate the incorporation of female researchers, especially in managerial positions. For its part, the Women and Science Commission of the CIC, in operation since 2006, has as its mission the development of women’s policies in the field of higher education and research.

During the celebration of the 15th Congress of ANECORM, the National Nursing Association Coordinating Materials Resources, awarded Marta Navarro Colom and Laura Romero Roca with the 13th Prize for a research work for the project Device for holding in bronchoscopies: study of concept and usability, that will be developed next year at the Interventional Pneumology Department of the Hospital de la Santa Creu i Sant Pau, in Barcelona.

The nurse and nursing assistant technician of this department come up with the idea of building a functional prototype of a device to maintain the immobilization of people undergoing flexible bronchoscopy and demonstrate through a study the usefulness of the prototype and its applications.

This project won in an initial phase a grant from The Collider On Campus (UAB-MWC), a 7-week online entrepreneurship program based on the Lean Launchpad methodology. This method helps to assess the commercialization feasibility of scientific and technological entrepreneurship projects, and to facilitate their development as a product.

ANECORM’s commitment guarantees the continuity of the product validation study and allows progress in the technological transfer process and the arrival of this health product in clinical practice.

This impulse represents a clear recognition of the nurse’s role in all phases of product development, in the innovative capacity and in the ease of multidisciplinary work with the 3D laboratory of the Hospital de Sant Pau and with the Technological Transfer and Innovation Unit of the Research Institute of Sant Pau – IIB Sant Pau.

The combination of preoperative chemoradiotherapy and transanal endoscopic microsurgery could be useful in helping to reduce local recurrence of rectal cancer. This therapeutic strategy could contribute to minimizing the sequelae in these patients. This is suggested by the results of the TAUTEM study, a phase III multicenter, randomized and controlled clinical trial published by the journal Annals of Oncology.

The research, in which Dr. Pilar Hernández, Dr. María del Carmen Martínez Sánchez and Dr. Eduardo Mª Targarona, researchers from the General and Digestive Surgery Group of the Santa Creu i Sant Pau Hospital Research Institute – IIB Sant Pau and specialists from the Gastrointestinal and Hematological Surgery Unit of the same hospital, has been led by Dr. Xavier Serra Aracil, from the Colorectal Surgery Research Group of the Parc Taulí Research and Innovation Institute (I3PT), in Sabadell.

Colorectal cancer is one of the most prevalent among the population. It is the second most common tumor among women – after breast cancer – and the third most common in men, only behind lung and prostate cancer. One in four cases of colorectal cancer affects the rectum.

Currently, the standard treatment for rectal cancer is surgery, which in most cases involves removing the rectum permanently. Patients who undergo this operation must live with a bag permanently or temporarily, and many may also suffer problems in the urinary bladder and present sexual dysfunctions, with all the consequences that this entails for their quality of life. life

This study suggests that, in the short term, the results of this new therapeutic strategy are equivalent to conventional treatment, but it represents a much less invasive option that allows the rectum to be preserved.

La Marató de TV3 Foundation will finance 4 mental health projects of the Sant Pau Biomedical Research Institute (IIB Sant Pau), thanks to the funds raised in the last edition, especially dedicated to these diseases.

One of the projects is led by Dra. Maria Portella and consists of a phase III clinical trial, randomized, controlled with an active comparator, to study the effectiveness and safety of the Integral Cognitive REMediation (INCREM) program in patients with depression.

On the other hand, Dr. Joaquim Soler will conduct a randomized controlled trial to evaluate the effectiveness of RODBT skills training in patients with eating disorders and autism spectrum traits, which will be a proof-of-concept study.

Dr. Javier de Diego Adeliño will carry out work on depression and the role and modulation of miRNAs in the anterior cingulate cortex as peripheral biomarkers and targets for promising nanotherapies, within the framework of a project coordinated by the CSIC.

In addition, Dr. Narcís Cardoner Álvarez will study the influence of the intestinal microbiota and derived metabolites in major depression in a neurometabolomics study of knowledge transfer in the irritable bowel and porcine model.

In total, 36 research projects, led by 81 research teams who are experts in mental health, will be financed with the funds raised in the last edition of La Marató de TV3 and Catalunya Ràdio.

At the event where the selected projects were made public, the researcher at the Santa Creu i Sant Pau Hospital Research Institute, Dra. M. Jesús Portella, representing all the awardees, thanked for the award and assured that he is aware of the responsibility that receiving these funds represents: “I want to thank the La Marató Foundation for dedicating a program to the mental health, which, with the solidarity of the people, allows us to carry out this research, which is what drives us.”

In the 2021 edition, 150 projects were presented, which were evaluated by 111 international scientists specializing in this subject based on their quality, methodology and relevance. The management of the evaluation was carried out by the Health Quality and Evaluation Agency of Catalonia, of the Department of Health.

A study in which Dr. José Martínez-González, researcher at the Instituto de Investigaciones Biomédicas de Barcelona (IIBB-CSIC) and the IIB-Sant Pau, carried out at the National Cardiovascular Research Center (CNIC), reveals a key factor that protects the heart after a heart attack.

The research, led by Dra. Pilar Martín, head of the Inflammatory Processes Regulatory Molecules Group of the CNIC and published today in the Journal of Clinical Investigation, describes that the expression of the CD69 receptor in regulatory T lymphocytes confers protection after suffering a myocardial infarction, since it acts as a control point for the exacerbated inflammation responsible for heart damage in the medium term.

In addition, the work in which researchers from the Cardiovascular Diseases area of the CIBER (CIBERCV) from the group of Dr. Francisco Sánchez-Madrid at the CNIC and the La Princesa University Hospital have also participated, reveals that expression levels of this CD69 receptor in peripheral blood could predict the development of heart failure, that is, serious sequelae in the functionality of the heart.

Regulatory T lymphocytes, explains Dr. Rafael Blanco-Domínguez, first signatory of the work, “are cells in charge of controlling other elements of the immune system to prevent uncontrolled inflammatory responses from ending up causing unwanted damage”.

The researchers, through the analysis of blood immunologic markers of 283 patients with myocardial infarction, ischemic heart disease and the main cause of death in the world, have discovered that there is an increase in the expression of this receptor CD69 in regulatory T lymphocytes in the first hours after the ischemic event.

Thanks to experiments with mouse models, this team of scientists has revealed that the absence of CD69 leads to an increase in inflammation, cardiac dysfunction and the death rate after a heart attack.

This phenomenon, explains Dra. Martín, “this is because the regulatory T cells that express CD69 are recruited at the site of the infarction and are necessary to inhibit the gamma-delta T cells, which secrete the pro-inflammatory interleukin-17. The presence of CD69 makes the regulatory T cells more efficient in inducing death and inhibiting the secretion of interleukin-17 by means of a novel mechanism independent of specific antigens”.

Research has also shown that a very relevant fact: therapy with regulatory T cells that express CD69 after a heart attack in mice deficient in CD69 is sufficient to compensate for the deficiency of this molecule and thus reduce cardiac inflammation and improve survival.

The follow-up of patients with heart attacks in two independent cohorts, in close collaboration with the Cardiology Services of the University Hospital of La Princesa in Madrid and the Hospital de la Santa Creu i Sant Pau in Barcelona, revealed another very promising result for the clinic.

The levels of expression of CD69 in peripheral blood serve to predict the development of heart failure, that is to say, serious sequelae in the functionality of the heart. In other words, explains Dr. Blanco-Domínguez, those patients with low levels of CD69 in the first hours after a heart attack “had a greater risk of developing heart failure during the first two and a half years after hospital admission”.

The authors conclude that this work reveals a new regulatory mechanism of inflammation after myocardial infarction and opens the door to the development of CD69 as a prognostic and therapeutic candidate for this global cardiac affectation.

“El temps és cervell”, afirma el Dr. Joan Martí-Fàbregas, cap de la Unitat d’Ictus del Servei de Neurologia de Sant Pau. Una frase que va en línia amb el lema del Dia Mundial de l’Ictus d’enguany: Els minuts poden salvar vides, però amb el missatge de que “l’èxit en ictus no només és sobreviure, sinó fer-ho amb qualitat de vida, de manera que els pacients tornin a ser funcionalment independents”.

L’Institut de Recerca de l’Hospital de la Santa Creu i Sant Pau, té dos grups dedicats a l’estudi de l’ictus: Malaltia Vascular Cerebral i Farmacogenòmica i Genètica Neurovascular.

El primer, dirigit pel Dr. Martí-Fàbregas, lidera estudis en ictus isquèmic:  beneficis i riscos de la trombòlisi intravenosa; beneficis i riscos del tractament endovascular (trombectomia mecànica), maneig de la pressió arterial post-trombectomia, circulació col·lateral en el pacient amb oclusió de gran vas, paper de les estatines en l’ictus isquèmic i hemorràgic; cèl·lules progenitores endotelials en ictus, vulnerabilitat de la placa carotídea ateroscleròtica; monitoratge no invasiu del flux cerebral amb mètodes òptics aplicats. També en hemorràgia intracerebral: prevenció de l’hemorràgia cerebral per anticoagulants; rellevància de l’edema perihematoma, influència de la microbiota, factors associats al creixement de l’hematoma, influència del tipus d’hospital i altres aspectes logístics en els resultats clínics.

El segon, que lidera el Dr. Israel Fernández, es focalitza en estudis genètics i epigenètics de l’ictus, participa en diversos consorcis internacionals i coordina un consorci estatal sobre el mateix tema que engloba el treball d’uns 15 hospitals i centres de recerca de l’Estat. Un dels darrers estudis publicats, en la revista Clinical Epigenetics, ha analitzat possibles canvis epigenètics que expliquin perquè no tots els pacients pateixen les mateixes alteracions neurològiques i la mateixa evolució. El treball conclou que podria ser degut a alteracions en la metilació d’un gen anomenat EXOC4, implicat en el procés conegut com a excitotoxicitat, pel qual les neurones són danyades i destruïdes en l’ictus.

El grup està duent a terme diversos projectes en el vessant farmacogenètic, sobre fàrmacs que s’utilitzen per prevenir l’ictus o per millorar la resposta dels pacients. L’equip està investigant si hi ha factors de risc genètic associats a l’evolució d’aquests pacients després de l’administració d’aquests fàrmacs i d’altra banda s’investiga sobre els factors genètics que predisposen a una resposta als fàrmacs que serveixen per prevenir l’aparició d’altres ictus en el mateix pacient.

Cada minut és important

Per això són cabdals la informació i les campanyes a la població per saber-ne identificar els primers símptomes i sol·licitar atenció mèdica urgent, rebre els tractaments apropiats a la fase aguda, l’ingrés en Unitats d’Ictus amb un equip de professionals multidisciplinari. També cal remarcar que l’ictus es pot prevenir, i tenim mesures per la prevenció primària i també en la prevenció secundària de l’ictus. Tant la prevenció com el tractament de la fase aguda són d’especial importància donat que l’ictus és la primera causa de discapacitat i la segona de mort.

Cal considerar l’ictus com una emergència mèdica tractable. “Quant més aviat arriba el pacient a l’Hospital, més podem fer per ell. Hem de poder revertir el procés i evitar possibles seqüeles per assolir una màxima capacitat de recuperació, és a dir, que el pacient torni a fer tot el que feia abans a nivell laboral, social, personal… Sobreviure no és un èxit, sí fer-ho amb qualitat de vida. Per això la població, des del mateix malalt fins a la seva família, els companys de feina… tothom ha de saber identificar els símptomes de sospita d’ictus”, segons el Dr. Martí-Fàbregas.

“El millor tractament aplicable per a tots els malalts és l’ingrés en una Unitat d’Ictus, com la que tenim a Sant Pau, igual que els malalts amb infart agut de miocardi ingressen en una Unitat Coronària. Està demostrat que això serveix per canviar l’evolució dels malalts”. A més, l’Hospital té una Comissió Multidisciplinària de l’Ictus, de manera que els professionals dels diferents Serveis i àmbits de tractament avaluen els casos un a un i proposen accions de millora que més tard es posen en pràctica en casos reals. Això ha permès avenços en la rapidesa d’administració de tractaments, esdevenint un dels hospitals amb millor temps de resposta i resultats clínics i un protocol compartit de derivació de pacients procedents del Sistema de Salut d’Andorra.

El Dr. Martí-Fàbregas destaca que “un element clau en l’abordatge de l’ictus és el treball multidisciplinari i coordinat entre els professionals” de Neurologia, Urgències, Anestèsia, Neuroradiologia, Radiologia Intervencionista, Infermeria quirúrgica, Infermeria d’Urgències, Fisioteràpia i Rehabilitació, Logopèdia, trasllat, i l’estreta col·laboració amb el Servei d’Emergències Mèdiques de Catalunya (SEM).

Sant Pau també participa en el Codi Ictus, el protocol d’actuació urgent del Sistema de Salut Públic de Catalunya que comprèn una xarxa de dispositius assistencials per donar una atenció immediata i adequada als pacients amb sospita d’ictus. Hi participen 29 hospitals.

Prevenció primària, però també secundària

L’ictus és el resultat d’una alteració de la circulació de la sang al cervell. Es classifiquen en ictus isquèmic (quan és degut a una obstrucció arterial i l’arribada de la sang a una zona del cervell s’altera i provoca que les cèl·lules cerebrals de l’àrea afectada morin per manca d’irri­gació sanguínia), i ictus hemorràgics (quan es trenca una artèria i s’acumula la sang en forma d’un hematoma a l’interior del cervell).

Es calcula que 1 de cada 6 persones tindrà un ictus en algun moment de la seva vida. Aquesta malaltia és més freqüent en homes, però més mortal en dones – en elles és la primera causa de mort per sobre dels 65 anys i, en ells, la tercera per sobre dels 75 anys.

A l’hora de prevenir-lo, hi ha una sèrie de factors no modificables, com l’edat i la genètica, per exemple, però també n’hi ha d’altres que podem canviar, com la hipertensió arterial, la diabetis, el sedentarisme, l’augment de colesterol, l’obesitat, el tabaquisme… “La feina comença quan donem d’alta els malalts amb ictus i tornen a casa seva, intentar que no tingui un segon episodi”.

Segons el Dr. Martí-Fàbregas, “afortunadament tenim tractaments molt eficaços en la fase aguda, de reperfusió, que tornen a enviar sang al teixit que s’ha quedat sense circulació com a conseqüència de l’ictus. Utilitzem fàrmacs com la trombòlisi intravenosa o altres que administrem de forma endovascular, com la trombectomia mecànica en la fase aguda”.

The clinical profiles of the post-COVID syndrome, that is, of the sequelae left by this disease after suffering it, are different depending on whether the patients have required hospital admission, if they have been in the ICU or if they have had the disease at home .

According to the results of a study led by Dr. Rosa Güell, a researcher at the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau and an expert in pulmonary rehabilitation, the patients who presented a more severe disease, that is, those who needed to go through the Intensive Care Unit, have a greater loss of muscle strength -especially of the lungs- and their effort capacity is lower compared to less severe patients. On the other hand, patients who were not admitted to the ICU presented more emotional sequelae and anxiety.

“Surprisingly, we have found that non-admitted patients, and even those admitted to the hospital but nor at the ICU, are worse from an emotional point of view. In other words, they have much more anxiety and depression compared to those admitted to the ICU”, details Dr. Güell.

“We do not know the explanation. Our hypothesis is that ICU patients received a lot of support from the beginning: from the physical therapist, from the medical team, from the nursing staff. Everyone was very attentive to them. So, it is very likely that they have had the feeling of accompaniment, in addition to the psychological effect of having overcome something very serious. This fact may have helped them reduce anxiety while those who have been in the room or at home may have felt more alone”, adds Dr. Güell.

Retrospective study

The article, published in the prestigious journal PLoS One, retrospectively compares the different symptom patterns in relation to the severity of acute COVID-19 in patients seen in the Post-COVID Rehabilitation Unit of the Hospital de Sant Pau.

The researchers studied different measures of respiratory, muscular, cognitive, emotional, and health-related quality of life in three groups of post-COVID patients: those who had not required hospitalization for the acute illness, those who had been admitted to a general hospital, and those who had been admitted to the ICU.

Specifically, the data of 178 post-COVID patients (91 admitted to the ICU, 60 on the ward and 27 who had not required admission) on their first visit to the Post-COVID Rehabilitation Unit were analyzed. The most frequent symptoms in all groups were fatigue (78.2%) and dyspnea or respiratory distress (75.4%). Muscle strength and exercise capacity were lower than the ICU group. The mental component and the level of anxiety were worse in patients not admitted to the ICU. No differences were found between groups in respiratory pressure, but 30 of 57 patients with a decrease in peak inspiratory pressure had not required mechanical ventilation.

Dr. Güell explains that it’s common for patients to lose muscle strength after being treated with mechanical ventilation for any reason. However, in this case, it has been found that many patients with COVID-19 who had not required mechanical ventilation had respiratory muscle weakness. “This finding makes us think that, possibly, this effect is not only due to muscle rest that favors mechanical ventilation and that there is surely a direct effect of the virus on the lung muscles.”

Continuous renal clearance techniques are a fundamental element for the treatment of many patients with acute renal failure associated with hemodynamic instability. To guarantee its proper administration and avoid complications, the work of the nursing staff of the intensive care units is key.

Despite the fact that there is more and more training on this subject aimed at nurses in ICUs, until now there has been no specific book on the subject. That is why Almudena Mateos Dávila, nurse manager of patients in the adult ICU of the Hospital de la Santa Creu i Sant Pau and researcher of the Nursing Care Research Group of the Hospital de la Santa Creu i Sant Pau Research Institute – IIB Sant Pau was given the task of writing the manual Conceptos fundamentales en terapias continuas de depuración renal para enfermeras (Círculo Rojo).

Throughout her professional career, the author has treated patients with many pathologies, but kidney failure has particularly caught her attention. She has specialized in this field as a student and now as a teacher. She coordinates the extracorporeal therapies working group at the Spanish Society of Intensive Nursing and Coronary Units (SEEIUC). She is a teacher of the renal subject in the Master’s Degree in Intensive Nursing at the Escola Universitaria de Infermeria (EUI) of the IIB Sant Pau, Barcelona. She is also a teacher and coordinates various courses, among which is the one on continuous depurative treatment in critical patients, which has completed its tenth edition within the Penélope program, at the Hospital de la Santa Creu i Sant Pau. Currently, she is researching citrate applied to continuous purifying therapies. This work is the subject of her doctoral thesis.

The project “Endometriosis in the first person: participatory research on the experiences and recommendations of women with endometriosis for the improvement of health services”, in which the Gynecology Service of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau has participated , is an innovative pilot that applies citizen science to women’s health within the framework of the European Project H2020 TRANSFORM. Women with endometriosis have been involved in it to delve into their experiences of the disease and their experiences regarding health services.

In the investigation, 20 patients diagnosed with endometriosis participated as co-investigators, having an active role in the data collection phases, in the formulation of recommendations and in the dissemination of the results.

Marta Fonseca has had endometriosis for 18 years, has undergone four surgeries and has participated in the pilot. “The fact of being in this group does not cure, but it helps a lot to share this experience and contribute to these recommendations. Yes, it is a complex disease, but if there are so many women who suffer from it, more attention must be paid to the various areas that endometriosis involves. You have to know that endometriosis exists and have better ways to deal with it with more informed professionals and resources dedicated to research.”

With the results of the research, a policy brief has been written for political decision-makers and health personnel, presenting the recommendations co-created by women for the improvement of health services.

The policy brief was presented yesterday at an event at the Hospital de Sant Pau that was attended by the women participating in the research and Gynecology professionals from the Hospital.

“The pilot and the policy brief aim to give voice and raise awareness about how endometriosis is experienced and its effects on people’s global health, as well as present recommendations to improve diagnostic and health care services.” Diana Reinoso, Project Manager at Science for Change.

The six general recommendations contained in the policy brief are:

1. Increase the degree of knowledge of endometriosis at the health level;

2. Develop strategies to achieve an early diagnosis of endometriosis;

3. Improve the process of transmitting information to patients to increase self-knowledge and contribute to shared decision-making;

4. Define and implement a comprehensive approach model for endometriosis;

5. Improve care for people with endometriosis in health services;

6. Develop more personalized treatment models that take into account the opinion of the patient.

The ultimate goal of the policy brief is to influence public health policies at regional and local level, and specifically, to influence the Endometriosis Care Model of Catalonia, in addition to the new model of innovative approach to the disease in the Hospital of Sant Pau.

Dr. Ramon Rovira, surgical coordinator of the Gynecology and Obstetrics Service of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau, in Barcelona, comments that “with the TRANSFORM project we have really put the patient at the center. It has been an opportunity, as a professional, to know first-hand what patients need and a possibility of radical improvement to face changes in the therapeutic approach to this pathology at all levels”.

In addition, he adds that the results of this initiative are “a clear example for new projects in different areas of health that allow a paradigmatic change in patient care, in general. Knowing what the patient needs is one of the obligations of the medical care of the future”.

For Nora Salas Seoane, Head of the Health Area of Science for Change, this pilot project is a clear example of how we can use citizen science, participatory strategies and co-creation in health to incorporate the patient’s experience and transform together with them certain health practices and their healthcare services.

“We are helping to understand women’s health from their perspective and their feelings, taking into account gender barriers in health. This pilot demonstrates that the patient’s experience is key and necessary to improve care services and influence the planning of health policies”, says Salas Seoane.

Dr. Teresa Padró, head of the Research Group on Biomarkers of the evolution of cardiovascular disease at the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau, has been appointed coordinator of the Coronary Pathophysiology Working Group and microcirculation from the European Society of Cardiology (ESC). She takes over from Prof. Dimitris Tousoulis, from the School of Medicine of the National and Kapodistrian University of Athens, in Greece.

This ESC working group, which includes both basic and clinical researchers, has among its main objectives the promotion of research to advance the integrative understanding of the physiology and pathophysiology of coronary vessels, better understand the mechanisms of prevention, diagnosis and treatment of coronary artery pathology through the promotion and coordination of preclinical and clinical studies.

In addition, its mission is to carry out informative tasks to offer professionals and the general population reliable and contrasted information related to coronary pathophysiology, microcirculation and ischemia. Also promote the participation of the members of this group in all kinds of scientific activities.

Sant Pau has a very active participation in this scientific society. Dr. Gemma Vilahur, from the group of Molecular and Therapeutic Pathology of Atherothrombotic and Ischemic Diseases of the Research Institute of the Hospital de la Santa Creu i Sant Pau, has been the coordinator, for the last two years, of the Working Group on Thrombosis of the ESC.

The scientific committee of the Congress of Neurological Surgeons (CNS) has chosen a study by the Research Institute of the Hospital de la Santa Creu i Sant Pau – IIB Sant Pau as the best manuscript of the year 2022 in the area of Neurofunctional and Stereotaxic Surgery. This is a study published in the journal Neurosurgery, whose main authors are Juan Ángel Aibar-Durán, from the Neurosurgery Service, and Francisco Javier de Diego, from the Psychiatry Service of this hospital.

This scientific meeting was held from October 7 to 11 in the city of San Francisco, United States, and is one of the obligatory dates of the specialty that brings together the most outstanding specialists from countries around the world to address scientific news in the field of neurosurgery.

The work, directed by Joan Molet, analyzes the long-term results of deep brain stimulation for the treatment of patients with major depression that did not respond to conventional treatments. In addition, it provides new clues about the mechanisms of action of this type of surgery.

As explained by Dr. Aibar-Durán, at 5 years of follow-up, of the patients with refractory depression included in this study, 80% showed improvement, so it could be concluded that this surgery is clearly effective in some patients.

Currently, deep brain stimulation is approved in some countries for the treatment of some disorders such as dystonia, tremors or Parkinson’s disease.

Sant Pau is the leading center in Spain and one of the main references in the world in this type of surgery and is the only public center in which neuromodulation is offered as an alternative in some selected patients with refractory severe depression. It is currently being tested in other indications as well, such as the treatment of schizophrenia.

The Research Institute of the Hospital de la Santa Creu i Sant Pau, as a CERCA center, is part of the new CERCAGINYS project. It is an access plataform to the different scientific and technical infrastructures of the research institutes and other centers that have this certification.

A total of 196 platforms are available from the 41 CERCA centers that are classified by category and by quality accreditation, among which are those of IR Sant Pau.

The initiative wants to optimize access to these facilities for the entire scientific and technological community, and, especially, it wants to demonstrate the possibility that the private business and industrial sector can also make use of them and be able to access the services of highly technical personnel qualified

This proposal is part of a wider project, linked to the Infrastructure Action Plan funded by the Ministry of Science and Innovation through I-CERCA. The agreement with the Ministry recognizes the existence of a system of centers in Catalonia and opens the door to the future creation of a virtual Singular Scientific and Technical Infrastructure (ICTS).
