A study by Germans Trias i Pujol Research Institute reveals that people living with HIV who contract COVID-19 face a significant increase in cardiovascular disease risk. The researchers identified several factors associated with this increased risk, including age, previous cardiovascular disease, and chronic conditions.
A clinical trial with PeriCord, a new tissue engineering product derived from umbilical cord and pericardium stem cells, confirms its feasibility in repairing damaged heart tissues after a heart attack. The therapy has demonstrated excellent biocompatibility and anti-inflammatory properties.
Researchers have developed new recommendations for optimizing TB screening programs in low-incidence countries. Screening high-risk groups, such as migrants and vulnerable populations, is a cost-effective approach that detects the disease early and prevents transmission.
A new R package, REDCapDM, enhances efficiency and reliability in managing research data collected through the popular REDCap platform. The tool provides functions for importing, transforming, identifying discrepancies, and managing data, simplifying the clinical data management process while ensuring quality and reliability.
Researchers have developed a novel immunotheraphy targeting macrophages to induce tolerance in type 1 diabetes, demonstrating its potential as a curative treatment. The therapy also shows promise for other autoimmune diseases, with results suggesting no impact on the immune system's ability to capture and process liposomes.
Researchers have discovered new genetic mechanisms related to spinocerebellar ataxia type 37, a rare neurological disorder that affects balance and movement. The study employed advanced techniques such as CRISPR/Cas9 gene editing and machine learning to uncover the disease's underlying causes.
Researchers have developed a new approach to treating cutaneous neurofibromas, a common skin tumor associated with neurofibromatosis type 1. By targeting the cAMP and Ras/MAPK pathways, this combination therapy may provide an enduring halt in the expansion of these tumors.
Researchers have found that alterations in the blood immune system increase cancer risk, and identified over 1,000 genes influencing this regulation. The study also discovered protective roles of certain immune cells against common cancers.
Researchers at Germans Trias i Pujol Research Institute have identified a combination of drugs that could change the treatment of patients with prostate cancer resistant to docetaxel. The study proposes a new treatment based on a combination of kinase inhibitors in patients who inevitably stop responding to docetaxel.
Two studies found people living with HIV in Catalonia have lower complete COVID-19 vaccination rates than those without HIV. However, they received more booster doses. Factors contributing to these disparities include previous SARS-CoV-2 diagnosis, socioeconomic situation and migration status.
Researchers discovered that apotransferrin can mitigate the damaging effects of intracerebral haemorrhage by guarding against ferropoptosis, a cell death process. This finding highlights the therapeutic potential of apotransferrin as a pre-hospital treatment for stroke patients.
A comprehensive review study identifies emerging biomarkers that mirror efforts to halt beta-cell autoimmunity, offering potential applications in clinical practice. The study's findings may improve the management of type 1 diabetes during its partial remission phase.
A collaborative study has developed an agarose spot migration assay to examine the ability of extracellular vesicles to attract other cells in a controlled environment. The assay revealed differences in EVs' recruitment capability for endothelial cells, particularly in highly metastatic cancer cells.
A collaborative study has identified key epigenetic targets for treating hepatoblastoma, the most common childhood liver cancer. The research found that the enzyme histone-lysine methyltransferase G9a plays a crucial role in epigenetic regulation and is a promising therapeutic target.
A pilot study in Catalonia found that self-sampling is a feasible and acceptable method for diagnosing asymptomatic mpox. The study identified 7 positive cases, including 3 asymptomatic individuals, and estimated the prevalence of infection at 6.19%.
A study published in Nature has identified 51 significant genome-wide loci associated with COVID-19 severity and SARS-CoV-2 susceptibility. The research adds 28 new loci to the list, providing valuable information about three key biological pathways involved in determining disease outcomes.
The BCG vaccine, primarily developed to prevent tuberculosis, was found ineffective against COVID-19 in a large international trial involving nearly 4,000 healthcare workers. Researchers discovered that vaccination increased the risk of symptomatic disease during the first six months following enrolment.
Researchers have developed a new immunotherapy targeting tumour macrophages, which are immunosuppressive cells that weaken the immune system. The treatment, RImAb, reduces tumour growth and modifies the tumour microenvironment, offering potential for a new line of treatment for lung cancer patients.
A novel stroke model in pigs has been established to mimic human cerebral artery occlusion and study mechanisms of ischemic stroke. The model's translational features make it suitable for testing new therapeutic compounds and devices.
A multidisciplinary group of experts has reached a consensus on key issues related to molecular prediction of Mycobacterium tuberculosis antibiotic sensitivity or resistance. The document provides guidance for therapeutic regimen design and treatment optimization, aiming to improve clinicians' management of TB patients.
A new genomic catalogue of malignant peripheral nerve tumour-derived lines has challenged current diagnostic criteria, revealing misdiagnosed cell lines and a shared cell line masquerading as different types. The catalogue provides new information to develop precision therapies for these tumours.
A new minimally invasive test using dried blood spots (DBS) has been shown to effectively assess cure after treatment and differentiate between reinfection and treatment failure. The results support the viability of decentralizing treatment for people who inject drugs, who often face challenges accessing healthcare.
A study has identified new microRNA biomarkers for the partial remission phase of type 1 diabetes and linked one of these microRNAs to immunoregulatory processes.
