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...

Initial treatment strategies and outcomes across haemodynamic thresholds and risk stratification in incident systemic sclerosis–associated pulmonary arterial hypertension: a EUSTAR analysis

OBJECTIVE: Real-world initial treatment strategies in SSc-PAH remain incompletely described. We aimed to characterise these strategies across haemodynamic thresholds and risk strata and evaluate outcome associations. METHODS: We analysed treatment-naïve SSc-PAH patients in EUSTAR...

Assessing Mental Health Without Relying on Psychiatric Data

Approximately one in seven people worldwide is affected by a mental disorder, making early identification crucial for preventing symptom progression and chronicity. However, diagnosis remains challenging, with discrepancies between referring physicians’ initial assessments and sp...

Effectiveness of interleukin (IL)-23 and IL-12/23 inhibitors and factors associated with response in psoriatic arthritis with axial involvement: the APxis-IL12-23 study

OBJECTIVES: To assess the real-world effectiveness of two interleukin (IL)-23 inhibitors [guselkumab (GUS), risankizumab (RIS)] and an IL-12/23 inhibitor [ustekinumab (UST)] in patients with purely axial psoriatic arthritis (PsA) or mixed PsA (both axial and peripheral involvemen...

Cutaneous Lymphoma International Prognostic Index and Risk Stratification in Advanced Mycosis Fungoides and Sézary Syndrome

Importance Risk stratification in advanced mycosis fungoides and Sézary syndrome (MF/SS) remains suboptimal given that current TNMB (tumor, node, metastasis, blood) staging has limited prognostic value for clinically relevant outcomes. Objective To determine whether the Cutaneous...

Rethinking CAR-T neurotoxicity in glioblastoma: immune activation within a preconditioned neuroinflammatory landscape

Abstract Chimeric antigen receptor (CAR) T-cell therapy has reshaped the treatment of hematologic malignancies, leading to remarkable responses in diseases that were once considered largely refractory. However, its translation to solid tumors, and particularly to glioblastoma (GB...

HIV-1 Drug Resistance in Mother–Infant Pairs in Southern Mozambique

This prospective nested cohort (EARTH) study evaluated drug resistance mutations and outcomes among 79 (31 with genetic results) early-treated Mozambican children living with HIV, followed for 50 months. Mortality reached 20.3%. Drug resistance mutations were detected in 58.1% of...

Vulnerability associated with sociodemographic and health determinants and survival after the Covid-19 Pandemic among women with functional dependence in the Orcasitas neighborhood of Madrid (Spain)

Background Population aging is a markedly female-dominated process, and this gender difference extends to functional dependence in performing activities of daily living (ADL). Understanding the situations that contribute to vulnerabilities which may lead to functional dependence,...

Validation of plasma core biomarkers of Alzheimer's disease: A multicenter study in usual practice conditions

Background The new anti-amyloid therapies have brought the challenge of early and feasible identification of Alzheimer's disease (AD). Plasma biomarkers are promising tools, but real-world evidence remains limited. Objective We aimed to evaluate the diagnostic performance of plas...

The Parkinsonian Motor Spectrum in Nonagenarians: A Population‐Based Study

BACKGROUND: Population-based data on mild parkinsonian signs (MPS) and parkinsonism in nonagenarians are scarce. OBJECTIVES: To estimate the prevalence of MPS, definite parkinsonism, and broader parkinsonian motor phenotypes; assess MPS after excluding idiopathic Parkinson diseas...

Lifestyle and its relationship with health literacy, sense of coherence and sociodemographic factors in a Spanish primary care population: a multicenter cross-sectional study

Health behaviors are driven by a complex interplay of individual and structural factors. While health literacy and sense of coherence are widely studied as psychosocial enablers of healthy lifestyles, evidence comparing their impact against broader social determinants of health r...

Clinical outcomes of stereotactic body radiotherapy in oligometastatic disease: a national real-world cohort study

Abstract Purpose We conducted the first multicentre Spanish real-world study assessing the efficacy and safety of stereotactic body radiotherapy (SBRT) in oligometastatic patients treated in routine clinical practice. Methods This retrospective, multicentre observational study in...

Population-based cohort study of modifiable risk factors for dementia and Alzheimer disease mortality in Spain

Abstract Background Although many modifiable factors are linked to dementia risk, their association with dementia and Alzheimer disease (AD) mortality remains unclear. We aimed to identify late-life modifiable factors associated with these outcomes and assess sex differences. Met...

Burden of diagnosed and undetected hyperkalemia in Spain: Clinical characteristics, management, healthcare resource utilization, and costs

BACKGROUND: Management of hyperkalemia (HK) is challenging and suboptimal. This study analyzed the prevalence of HK and undetected HK, as well as management, clinical outcomes, healthcare resource utilization (HCRU), and costs. METHODS: Observational study comprising cross-sectio...

Milvexian with Antiplatelet Therapy after Acute Coronary Syndrome Event

BackgroundPatients are at increased risk for recurrent ischemic events after an acute coronary syndrome event. Milvexian, an oral factor XIa inhibitor, may reduce the risk of major adverse clinical events with minimal bleeding risk. MethodsIn this phase 3, randomized, placebo-con...

Functional assessment of inherited myeloid neoplasm‐associated SAMD9L germline variants via Monoallelic CRISPR modelling

Summary While the majority of myeloid neoplasms are sporadic, the increasing application of germline genetic testing has led the World Health Organization to designate ‘ Myeloid malignancies with germline predisposition’ as a distinct clinical entity, carrying major implications...

Deep molecular profiling of lung neuroendocrine tumours and supra-carcinoids

BACKGROUND: Lung neuroendocrine tumours (NETs, also known as carcinoids) are rapidly rising in incidence worldwide but have unknown aetiology and limited therapeutic options beyond surgery. The current WHO classification, based on mitotic count and presence or absence of necrosis...

A Drug‐Gated, Modular STAb‐T Immunotherapy With External Control

ABSTRACT Living cell therapies lack robust, reversible mechanisms for externally controlling therapeutic activity after administration, limiting their safety and clinical adaptability. Here we engineer a drug‐gated cellular immunotherapy platform in which T cells function as prog...
