Targetable treatment resistance in thyroid cancer with clonal hematopoiesis.

Anaplastic thyroid cancer (ATC) is a clinically aggressive malignancy with a dismal prognosis. Combined BRAF/MEK inhibition offers significant therapeutic benefit in patients with -mutant ATCs. However, relapses are common and overall survival remains poor.

Influence of the Culture Conditions on Cell Cultures.

Since the last century, it has been shown that dedifferentiated cells of can produce catechins and other secondary metabolites under in vitro conditions, with potential applications in the cosmetic, pharmaceutical and food industries. In this work, cell suspension cultures of a cell line (LSC-5Y) were established in a liquid medium in order to optimize the biomass productivity, catechin monomer (GC, EGC, C, EC, CG, and ECG) and alkaloid (TB and CAF) productivity. The following factors were evaluated: concentration of growth regulators (BA and IBA), inoculum size, age of the cell line, light exposure, and effect of biotic elicitors (MeJA and extracts of ).

Methods: Multicentre, longitudinal study of a cohort of 4219 patients with SLE enrolled in the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI).

Cancer risk with biologic and targeted synthetic DMARDs in patients with rheumatic diseases and previous malignancies: Results from the BIOBADASER register.

Objective: to investigate the occurrence and relative risk of incident malignancy in patients with rheumatic diseases and previous malignancies treated with biologic and targeted synthetic DMARDs (b/tsDMARDs).

Methods: Cohort study of patients included in BIOBADASER 3.0 up to 2021, treated with b/tsDMARDs and history of a previous malignancy.

Blockade of IL-6 signaling alleviates atherosclerosis in -deficient clonal hematopoiesis.

Clonal hematopoiesis (CH) increases the risk of atherosclerotic cardiovascular disease possibly due to increased plaque inflammation. Human studies suggest that limitation of interleukin-6 (IL-6) signaling could be beneficial in people with large CH clones, particularly in CH. Here we show that IL-6 receptor antibody treatment reverses the atherosclerosis promoted by CH, with reduction of monocytosis, lesional macrophage burden and macrophage colony-stimulating factor 1 receptor (CSF1R) expression.

Pregnancy outcomes in 1869 pregnancies in a large cohort from the Spanish Society of Rheumatology Lupus Register (RELESSER).

Introduction: Obstetric complications are more common in women with systemic lupus erythematosus (SLE) than in the general population.

Objective: To assess pregnancy outcomes in women with SLE from the RELESSER cohort after 12 years of follow-up.

Methods: A multicentre retrospective observational study was conducted.

Search for Gamma-Ray Spectral Lines from Dark Matter Annihilation up to 100 TeV toward the Galactic Center with MAGIC.

Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV.

Optimisation of tocilizumab therapy in giant cell arteritis. A multicentre real-life study of 471 patients.

Objectives: Tocilizumab (TCZ) is the only biologic therapy approved for giant cell arteritis (GCA). There is general agreement on the initial/maintenance dose, duration of TCZ therapy is not well established. In GiACTA trial, after one year on TCZ, most patients had GCA relapse after withdrawal.

Frequency of hereditary transthyretin amyloidosis among elderly patients with transthyretin cardiomyopathy.

Aims: Transthyretin amyloid cardiomyopathy (ATTR-CM) is increasingly recognized as a cause of heart failure in the elderly. Although wild-type transthyretin amyloidosis is the most frequent form of ATTR-CM found in the elderly, hereditary transthyretin amyloidosis (ATTRv) can also occur. We sought to determine the prevalence of ATTRv among elderly ATTR-CM patients, identify predictors of ATTRv and evaluate the clinical consequences of positive genetic testing in this population.

Tocilizumab in visual involvement of giant cell arteritis: a multicenter study of 471 patients.

Background: Visual involvement is the most feared complication of giant cell arteritis (GCA). Information on the efficacy of tocilizumab (TCZ) for this complication is scarce and controversial.

Objective: We assessed a wide series of GCA treated with TCZ, to evaluate its role in the prevention of new visual complications and its efficacy when this manifestation was already present before the initiation of TCZ.

Multidisciplinary models for pregnancy care in patients with rheumatic diseases: Clinical experiences and experts opinion.

Objectives: To describe different models of multidisciplinary pregnancy care for patients with inflammatory and autoimmune rheumatic diseases, and the steps to follow concerning their implementation.

Methods: A qualitative study was conducted including: (1) a comprehensive literature search in PUBMED focused on multidisciplinary care models; (2) structured interviews with seven rheumatologists from multidisciplinary pregnancy clinics for patients with inflammatory and autoimmune rheumatic diseases. Data were collected related to the hospitals, medical departments, populations cared for, and multidisciplinary care models (type, material, and human resources, professional requirements, objectives, referral criteria, agendas, protocols, responsibilities, decision-making, research and educational activities, multidisciplinary clinical sessions, initiation/start, planning, advantages/disadvantages, and barriers/facilitators for implementation); (3) a nominal meeting group in which the results of searches and interviews were analyzed and the recommendations for the implementation of the multidisciplinary care models defined.

Role of targeted therapies in rheumatic patients on COVID-19 outcomes: results from the COVIDSER study.

Objectives: To analyse the effect of targeted therapies, either biological (b) disease-modifying antirheumatic drugs (DMARDs), targeted synthetic (ts) DMARDs and other factors (demographics, comorbidities or COVID-19 symptoms) on the risk of COVID-19 related hospitalisation in patients with inflammatory rheumatic diseases.

Methods: The COVIDSER study is an observational cohort including 7782 patients with inflammatory rheumatic diseases. Multivariable logistic regression was used to estimate ORs and 95% CIs of hospitalisation.

Prognostic Implications of Neutrophil Extracellular Traps in Coronary Thrombi of Patients with ST-Elevation Myocardial Infarction.

Aims:  The mechanisms of coronary thrombosis can influence prognosis after ST-elevation myocardial infarction (STEMI) and allow for different treatment groups to be identified; an association between neutrophil extracellular traps (NETs) and unfavorable clinical outcomes has been suggested. Our aim was to determine the role played by NETs in coronary thrombosis and their influence on prognosis. The role of other histological features in prognosis and the association between NETs and bacteria in the coronary thrombi were also explored.

Objective: To assess the efficacy and safety of tocilizumab (TCZ) in Caucasian patients with refractory Takayasu's arteritis (TAK) in clinical practice.

Methods: A multicenter study of Caucasian patients with refractory TAK who received TCZ. The outcome variables were remission, glucocorticoid-sparing effect, improvement in imaging techniques, and adverse events.

A JAK/STAT-mediated inflammatory signaling cascade drives oncogenesis in AF10-rearranged AML.

Leukemias bearing fusions of the AF10/MLLT10 gene are associated with poor prognosis, and therapies targeting these fusion proteins (FPs) are lacking. To understand mechanisms underlying AF10 fusion-mediated leukemogenesis, we generated inducible mouse models of acute myeloid leukemia (AML) driven by the most common AF10 FPs, PICALM/CALM-AF10 and KMT2A/MLL-AF10, and performed comprehensive characterization of the disease using transcriptomic, epigenomic, proteomic, and functional genomic approaches. Our studies provide a detailed map of gene networks and protein interactors associated with key AF10 fusions involved in leukemia.

Bounds on Lorentz Invariance Violation from MAGIC Observation of GRB 190114C.

On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ray burst. We use this unique observation to probe an energy dependence of the speed of light in vacuo for photons as predicted by several quantum gravity models.
