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...

Association Between the GMI / HbA1c Ratio and Microvascular Complications in Type 1 Diabetes: A Multicenter Cross‐Sectional Study

ABSTRACT Objective To clarify whether the glucose management indicator (GMI)/glycated haemoglobin (HbA1c) ratio (GMI/HbA1c ratio) is an independent predictor of microvascular complications in Type 1 diabetes (T1D). Design and Methods Multicentre, cross‐sectional, observational st...

Hospital-linked and community-based viral hepatitis screening among Romanian migrants in Seville: A feasibility study

Introduction Romanian migrants may be at increased risk of viral hepatitis because many originate from countries with intermediate or high endemicity. Targeted, culturally adapted screening strategies are therefore needed to improve case finding and prevention. Our aim was to exp...

Real-world safety and clinical outcomes of cluster subcutaneous immunotherapy with olive pollen extracts, with or without grass pollen, in patients with allergic rhinoconjunctivitis and/or asthma

Abstract Background Allergen immunotherapy (AIT) is the only treatment capable of modifying the natural course of IgE-mediated allergic diseases induced by aeroallergens. Cluster schedules for subcutaneous AIT (SCIT) with hypoallergenic depot extracts enable faster dose escalatio...

Impulsivity in cluster headache: a case–control genetic association study

Impulsivity has received limited attention in cluster headache (CH), despite growing evidence of a broader behavioral phenotype in the disorder. We aimed to compare impulsivity between patients with CH and healthy controls and to explore associations between selected candidate ge...

Artificial intelligence for clinical data extraction from EHRs in breast cancer trials: the MIRROR study

Manual data entry and curation is the most used method of data collection for real world evidence and clinical trials but is a time-consuming task associated with significant human effort and transcription mistakes. MIRROR is a retrospective study that compared manual data captur...

Health utilities in individuals with alpha-1 antitrypsin deficiency with and without COPD from the EARCO registry

Background Data on health utilities in Alpha-1 antitrypsin deficiency (AATD) are scarce. This study aimed to evaluate health-related quality of life (HRQoL) using the EQ-5D in a cohort of AATD Pi*ZZ individuals from the European AATD Research Collaboration (EARCO) registry and to...

Evidence-based atlas of risk and protective factors for psychotic disorders: an umbrella review to inform personalized prognosis and prevention.

Identifying updated, evidence-based risk and protective factors for psychotic disorders is essential to advancing scientific and clinical knowledge of their etiology. Since the most recent umbrella review published in this journal, the evidence base has expanded substantially. Fo...

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...

Hypofractionation in Unresectable Stage II-III NSCLC: A Systematic Technical Review and Practical Recommendations

Background: Concurrent chemoradiotherapy (cCRT) followed by 1 year of consolidation durvalumab remains the standard of care for unresectable stage III non-small cell lung cancer (NSCLC), yet long-term survival is still limited and around 20% of patients present locoregional relap...

The Global Airways Unit: A Multidisciplinary Strategy for Early Diagnosis and Comorbidity Detection

ABSTRACT Background Chronic respiratory diseases impose a large global burden of morbidity, mortality, and cost. The concept of a global airway has become increasingly supported by epidemiologic, mechanistic, and clinical evidence. However, clinical care often remains fragmented...

Effect of Aficamten on Cardiac Structure and Function in Patients with Symptomatic Nonobstructive Hypertrophic Cardiomyopathy

BACKGROUND: Aficamten significantly improved both functional capacity and patient-reported health status in patients with symptomatic nonobstructive hypertrophic cardiomyopathy in the phase 3 randomized, placebo-controlled ACACIA-HCM trial (Assessment Comparing Aficamten to Place...

Global Efficacy of Aficamten in Nonobstructive Hypertrophic Cardiomyopathy: Results From ACACIA-HCM

BACKGROUND: Nonobstructive hypertrophic cardiomyopathy (nHCM) is associated with significant morbidity with no approved treatment. Aficamten is a cardiac myosin inhibitor targeting excess contractility and diastolic impairment, the predominant mechanism responsible for adverse ou...

Aficamten for Symptomatic Nonobstructive Hypertrophic Cardiomyopathy

BACKGROUND: Nonobstructive hypertrophic cardiomyopathy (HCM) is a common condition that is associated with substantial morbidity and no proven medical therapy. Whether treatment with aficamten, a cardiac myosin inhibitor, can benefit patients with this condition is unknown. METHO...

Trop-2 overexpression as a prognostic marker in early triple-negative breast cancer: results from the GEICAM_CIBOMA trial

Trophoblast cell-surface antigen 2 (Trop-2) is a key therapeutic target in metastatic triple-negative breast cancer (TNBC), yet its prognostic significance in early-stage disease remains poorly defined. We evaluated Trop-2 expression and its clinical impact within a sub-cohort of...

Incidence, Causes, and Outcomes of Conversion to Open Surgery During Minimally Invasive Left Pancreatectomy: A Prospective Multicenter Study

ABSTRACT Background Minimally invasive left pancreatectomy (MILP) has become the preferred approach to treat lesions of the pancreatic body and tail. However, the procedure may require conversion to open surgery, with reported conversion rates varying widely in the literature. Th...

Cord blood DNA methylation differences associated with gestational diabetes and partial consistency with maternal methylation patterns

Gestational diabetes mellitus (GDM) increases offspring cardiometabolic risk, potentially through intrauterine epigenetic programming. We aimed to characterize GDM-associated DNA methylation differences in cord blood, evaluate their consistency with previously identified maternal...

Malnutrition Severity, Morphofunctional Assessment, and Survival in Patients with Lung Cancer: A Multicentre Prospective Cohort Study

PURPOSE: Malnutrition is common in lung cancer and may contribute to impaired functional status and poor survival. This study evaluated the association between GLIM-defined malnutrition, morphofunctional nutritional parameters, and one-year mortality in patients with lung cancer....

The narrowing sex gap in lip and oral cavity cancer incidence in Spain: Thirty years of divergent age-period-cohort trends

Background Lip and oral cavity cancer (LOCC) accounts for a significant proportion of the overall burden of head and neck cancers, yet long-term sex-specific trends remain unclear. This study aimed to analyse sex-specific LOCC incidence trends in Spain from 1994 to 2023. Methods...

Expanding the Role of Dalbavancin in Children: A Case Series and Systematic Review

BACKGROUND: Dalbavancin is a long-acting lipoglycopeptide antibiotic with activity against Gram-positive bacteria and is approved for the treatment of acute bacterial skin and skin structure infections. Its pharmacokinetic profile and tolerability make it an attractive option for...
