Introduction: MSCs exhibit regenerative, anti-inflammatory and immunomodulatory properties due to the large amount of cytokines, chemokines and growth factors they secrete. MSCs have been extensively evaluated in clinical trials, however, in some cases their therapeutic effects are variable. Therefore, strategies to improve their therapeutic potential, such as preconditioning with proinflammatory factors, have been proposed.

Frequency of remission achievement in the pre-treat-to-target decade in juvenile idiopathic arthritis.

Pediatr Rheumatol Online J

January 2025

Dipartimento di Neuroscienze, Riabilitazione, Oftalmologia, Genetica e Scienze Materno- Infantili (DINOGMI), Università Degli Studi Di Genova, Genoa, Italy.

Background: Over the past two decades there has been a remarkable advance in the management of juvenile idiopathic arthritis (JIA), which has led to considerable improvement in prognosis. In 2018, the introduction of the treat-to-target (T2T) strategy in JIA has been advocated to further ameliorate disease outcome. To provide a benchmark for comparing future outcomes in the "T2T era", this study investigates the percentage of JIA patients who achieved clinical inactive disease (CID) in the decade that preceded the publication of the T2T recommendations in JIA.

Objectives: To develop an EULAR training model for education in synovial tissue biopsy (STB) under ultrasound guidance (UG) following a stepwise approach: (1) development of educational material on UGSTB in large and small joints; (2) assessment of the validity, reliability and feasibility of the UGSTB educational procedure on cadaveric specimens; (3) validation of this procedure in live patients.

Methods: Using a nominal group (NG) and a DELPHI consensus methodology, educational audio-visual (AV) material and minimal requirements for education in UGSTB were developed by an expert panel. Then the experts performed an UGSTB on cadaveric joints using the developed approach.

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive malignancy that frequently presents with extranodal involvement. Cutaneous tropism is clinically and histopathologically variable, which may pose a diagnostic challenge. We conducted a retrospective analysis of 40 samples of 20 cases of cutaneous AITL, focusing on the clinicopathologic and molecular correlations between skin and lymph node (LN) samples.

Value of ultrasound-assessed dactylitis in the early diagnosis of psoriatic arthritis.

Semin Arthritis Rheum

February 2025

Department of Rheumatology and Joint and Bone Research Unit. Fundación Jiménez Díaz University Hospital and Health Research Institute Fundación Jiménez Díaz (IIS-FJD, UAM), Autonomous University of Madrid, Madrid, Spain. Electronic address:

Purpose: The primary objective of this prospective, longitudinal, observational, single-centre study was to evaluate the association between ultrasound-assessed lesions of dactylitis and the diagnosis of psoriatic arthritis (PsA) in patients with psoriasis (PsO) and hand arthralgia.

Methods: We included adult patients diagnosed with PsO with hand arthralgia, with or without other musculoskeletal complaints. They were clinically assessed at baseline, 6 and 12 months by a rheumatologist blinded to the ultrasound findings.

Biomedical Innovation Unit, Center for Research on Energy, Environment and Technology (CIEMAT), Madrid, Spain; Biomedical Network Research Center for Rare Diseases (CIBERER), Madrid, Spain; Sanitary Research Institute Fundación Jiménez Díaz (U.A.M), Madrid, Spain. Electronic address:

Background: Allogeneic haematopoietic stem-cell transplantation is the standard treatment for bone marrow failure (BMF) in patients with Fanconi anaemia, but transplantation-associated complications such as an increased incidence of subsequent cancer are frequent. The aim of this study was to evaluate the safety and efficacy of the infusion of autologous gene-corrected haematopoietic stem cells as an alternative therapy for these patients.

Methods: This was an open-label, investigator-initiated phase 1/2 clinical trial (FANCOLEN-1) and long-term follow-up trial (up to 7 years post-treatment) in Spain.

Glutathione Peroxidases: An Emerging and Promising Therapeutic Target for Pancreatic Cancer Treatment.

Antioxidants (Basel)

November 2024

Translational Oncology Division, OncoHealth Institute, Health Research Institute Fundación Jimenez Diaz, Fundación Jimenez Díaz University Hospital, Universidad Autonoma de Madrid (IIS-FJD, UAM), 28040 Madrid, Spain.

Glutathione peroxidases (GPxs) are a family of enzymes that play a critical role in cellular redox homeostasis through the reduction of lipid hydroperoxides to alcohols, using glutathione as a substrate. Among them, GPx4 is particularly of interest in the regulation of ferroptosis, a form of iron-dependent programmed cell death driven by the accumulation of lipid peroxides in the endoplasmic reticulum, mitochondria, and plasma membrane. Ferroptosis has emerged as a crucial pathway in the context of cancer, particularly pancreatic cancer, which is notoriously resistant to conventional therapies.

Background: Alveolar soft-part sarcoma (ASPS) is a rare tumor driven by the ASPSCR1-TFE3 fusion protein, with a propensity for metastasis. Prognostic factors remain poorly understood, and traditional chemotherapies are largely ineffective. Recent interest lies in immune checkpoint inhibitors (ICIs), yet predictive biomarkers for treatment response are lacking.

Article Synopsis
  • A study aimed at understanding colorectal cancer (CRC) biology identified early diagnostic markers through quantitative proteomics of tissue samples from patients with stage I sporadic CRC.
  • Two experiments using advanced mass spectrometry techniques revealed 2,681 proteins, with 284 upregulated and 280 downregulated in adenoma and adenocarcinoma tissues compared to healthy samples.
  • Further investigation of ten dysregulated proteins showed that SLC8A1 and TXNDC17 are crucial for CRC development and could serve as potential early diagnostic markers in plasma tests.

Oval cells (OCs) is the name of hepatic progenitor cells (HPCs) in rodents. They are a small population of cells in the liver with the remarkable ability to proliferate and regenerate hepatocytes and cholangiocytes in response to acute liver damage. Isolating OCs generally requires a pretreatment with special diets, chemicals, and/or surgery to induce hepatic damage and OC proliferation in mice.

Importance: Governments worldwide have become increasingly cognizant of the spread of genetic discrimination (negative treatment or harm on the basis of actual or presumed genetic characteristics). Despite efforts by a number of governments to establish regulations addressing this phenomenon, public concern about genetic discrimination persists.

Objective: To identify key elements of an optimal genetic nondiscrimination policy and inform policymakers as they seek to allay genetic nondiscrimination and related public anxieties.

Chronic obstructive pulmonary disease is a common chronic lung disease with an ever-increasing incidence. Despite years of drug research and approvals, we are still not able to halt progress or restore normal lung function. Our previous studies have demonstrated that liver growth factor-LGF has an effect on the repair of the affected tissue in a mouse model of cigarette smoke exposure, but by what pathways it achieves this is unknown.

Background: Gastrointestinal stromal tumours (GISTs) are prevalent mesenchymal tumours of the gastrointestinal tract, commonly exhibiting structural variations in and genes. While the mutational profiling of somatic tumours is well described, the genes behind the susceptibility to develop GIST are not yet fully discovered. This study explores the genomic landscape of two primary GIST cases, aiming to identify shared germline pathogenic variants and shed light on potential key players in tumourigenesis.

Article Synopsis
  • Prognostic biomarkers are important for understanding sporadic desmoid tumors (DT) due to their unpredictable nature; this study focused on gene expression differences between DTs located in the thoracic versus abdominal wall.
  • A retrospective analysis of 197 sporadic DT patients showed significant relationships between relapse-free survival (RFS) and factors like tumor size, location, and specific gene mutations, notably the CTNNB1 T41A and S45F mutations.
  • Results suggest that tumors in the abdominal wall have a better prognosis compared to extra-abdominal locations, with distinct gene expression profiles influencing cancer pathways related to their behavior and outcomes.
