Genomic and clinical landscape of RAS mutations in acute myeloid leukemia

RAS mutations are recurrent in acute myeloid leukemia (AML); yet, their genomic and clinical landscape remain poorly characterized. We analyzed centralized molecular profiling data in 8,553 patients with newly diagnosed AML. Of these, 1,775 (21%) harbored RAS mutations: NRAS in 1...

Early measurement of ST2 and REG3α has a prognostic impact in haploidentical transplantation with post-transplant cyclophosphamide

Research on predictive biomarkers in haploidentical SCT (haplo-HSCT) with post-transplant cyclophosphamide (PTCy) remains limited, particularly regarding the critical first week post-infusion. We prospectively evaluated serum ST2, REG3α, and the MAGIC algorithm pre-conditioning a...

Effectiveness of a Physical Exercise Prescription Program in Primary Care to Improve Physical Fitness and Quality of Life in Adults Aged 65 Years and Older in a Rural Basic Health Area—Study Protocol for a Randomized Controlled Trial (PREFIS-AP)

Physical inactivity contributes substantially to morbidity, disability, functional decline, and premature mortality in older adults. General physical activity counselling in primary care does not necessarily translate into structured, individualized exercise prescription. PREFIS-...

Mediterranean Diet Adherence and Sleep Quality in Spanish Adults: Divergent Associations Between Subjective and Objective Measures

Objective: We aimed to examine the association between adherence to the Mediterranean diet (MD) and sleep quality assessed using both subjective and objective methods in a general adult population. Design: This is a cross-sectional study. Adherence to the MD was evaluated using t...

Validation of the International Working Group 2023 response criteria for higher risk myelodysplastic syndromes/neoplasms using the International Consortium for Myelodysplastic Syndromes VALIDATE database and a randomized phase III trial

Response assessment criteria in patients with higher-risk myelodysplastic syndromes/neoplasms (HR-MDS) have been updated in the 2023 International Working Group (IWG) criteria. However, validation of these criteria has been limited to date. We analyzed overall survival (OS) by be...

Gamified IMU Sensor-Based System for Training Head-Orientation Tasks in Healthy Teenagers: Event-Driven Architecture and Randomised Pilot Feasibility Study

Sensor systems integrated with gamified environments have increasingly been incorporated into the monitoring of musculoskeletal disorders. This study evaluates the operational feasibility of a motion-capture system based on an inertial measurement unit for training head-orientati...

Zinc Homeostasis in Brucella ovis Under Zinc Scarcity: Characterization of the ZnuABC Zinc Import System and of a Newly Identified Gene of the Zur Regulon

The zinc import system ZnuABC is essential for the virulence of smooth (bearing O-polysaccharide chains) zoonotic Brucella species but remains uncharacterized in the non-zoonotic rough (lacking O-chains) species Brucella ovis, the causative agent of a type of ovine brucellosis of...

Three clinical and immunological phenotypes of systemic lupus erythematosus onset identified through clustering analysis: data from the RELES registry

Abstract Background Systemic lupus erythematosus (SLE) shows heterogeneous clinical expression at onset, complicating early characterisation and risk assessment. We aimed to identify SLE phenotypes emerging after diagnosis and assess their clinical relevance. Methods We analysed...

Effectiveness of Interventions for Reducing Loneliness Among Adult Cancer Survivors: A Systematic Review and Meta-Analysis

Background/Objectives: Loneliness in adult cancer survivors is a frequent and disruptive psychosocial sequela with important consequences for overall health. Psychosocial interventions designed to address this issue are crucial. This systematic review and meta-analysis aimed to e...

Antibody-drug conjugate engineering: from design to efficacy and safety

Antibody–drug conjugates (ADCs) represent a rapidly expanding class of targeted cancer therapeutics that combine the high selectivity of monoclonal antibodies with the potent cytotoxic activity of small-molecule drugs. Their clinical success relies on the simultaneous optimizatio...

Associations Between Chocolate Consumption and Cardiometabolic Risk Markers Across Metabolic Profiles: Insights from a Population-Based Study

Background/Objectives: Studies evaluating the association between chocolate consumption and cardiometabolic health have reported inconsistent findings, and whether these associations differ according to underlying metabolic status remains unclear. This cross-sectional study analy...

Machine learning provides individualized prediction of outcomes after first complete remission without allo‐HSCT consolidation in adult acute myeloid leukemia—A HARMONY study

Abstract Allogeneic hematopoietic stem cell transplantation (allo‐HSCT) is a curative treatment option for a significant proportion of patients with acute myeloid leukemia (AML), and it is generally recommended when the relapse risk without allo‐HSCT outweighs the estimated non‐r...

Talquetamab for people living with relapsed/ refractory multiple myeloma: plain language summary of the MonumenTAL-1 study

Plain Language SummaryWhat is this summary about?This summary describes how well talquetamab worked and its safety at a median (midpoint) of 17–26 months follow-up from the MonumenTAL-1 study, which tested talquetamab treatment for a type of cancer called relapsed/refractory mult...

Variation in meningioma recurrence risk estimates across observational cohorts: the influence of calendar time, WHO classifications, geographical settings, and healthcare systems

Abstract Purpose Recurrence risk estimates underpin meningioma research, including molecular classification and clinical trial benchmarking, yet are often based on retrospective or historical data. The aim of this study was to assess the variation of recurrence risk estimates acr...

A RAC1 SUMOylation switch governs breast cancer metastasis

Despite the major advances in breast cancer management over the past few decades, metastatic breast cancer continues to be a major concern and the main cause of mortality associated with this disease. The Rho GTPase RAC1 has been implicated in breast cancer aggressiveness, yet th...

BioFRAM PGx, an Implementation Proposal for Pharmacogenetics in the Spanish National Health System

Background/Objectives: Pharmacogenetics (PGx) may improve drug safety and effectiveness, but its integration into routine care remains heterogeneous across the Spanish National Health System (NHS). This article presents BioFRAM PGx, a multicentre implementation framework that def...

Evidence-based interventions for vocational recovery in first-episode psychosis: A meta-analysis of employment and education rates

Background: Young people with first-episode psychosis experience high rates of disruption in work and education and consistently describe vocational participation as a core priority of recovery. This meta-analysis aimed to evaluate the effectiveness of evidence-based intervention...
