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...

Use of Oxygen in the Emergency Department

ABSTRACT Oxygen is one of the most frequently used treatments in the emergency department (ED), but it should be prescribed and reassessed as an active therapy rather than left as a harmless default. Acute hypoxemia may reflect ventilation-perfusion mismatch, shunt, hypoventilati...

Emergency Department-Based Screening and Linkage-to-Care for Hepatitis B, C, and D in a Referral Hospital in Barcelona, Spain: Reduction in Hepatitis C Prevalence After Five Years

Background: Emergency Department (ED) viral hepatitis screening programs typically report short-term outcomes. We evaluated the medium-term impact of an ED-based screening for Hepatitis C (HCV), Hepatitis B (HBV), and Hepatitis D (HDV) viruses. Methods: Prospective opportunistic...

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...

Reduced-frequency bictegravir, emtricitabine, and tenofovir alafenamide in virologically suppressed adults with HIV: a single-centre randomised phase 2 pilot trial in Spain

Background Reduced-frequency oral antiretroviral therapy may lessen treatment burden, but the exposure thresholds required to maintain virological suppression and the role of the HIV reservoir remain undefined. Methods BETAF-RED was a 48-week, single-centre, randomised, open-labe...

Tumor Necrosis is Associated with an Increased Metastatic and Cardiovascular Risk in Paragangliomas: A Single-Center Series and Meta-Analysis Comparing Necrosis and Cystic Degeneration in Paragangliomas

Abstract Paragangliomas (PGLs) are rare neural crest–derived tumors with highly variable morphology and clinical behavior. These tumors can present with cystic and necrotic alterations that may influence the clinical presentation of affected patients. However, prevalence and clin...

Protocol for a feasibility randomized controlled pilot trial evaluating a teacher program to support preschool children with autism and language delay

Abstract Background Early intervention in naturalistic settings is essential for supporting young children with difficulties within the autism spectrum. In recent decades, there has been an increasing inclusion of children with developmental problems in mainstream schools. Howeve...

Expanding CIRdb, a comprehensive catalog of whole-exome sequencing data of Canary Islanders.

) gene, which is associated with body mass index, cardiovascular health, and metabolic and respiratory traits. Taken together, our findings show that CIRdb presents a valuable resource of exome-wide genetic variation in a population at the edge of Southwestern European genetic di...

Neurobiological correlates of longitudinal grey matter volume changes in preclinical Alzheimer’s disease

Background: Structural brain changes during the earliest asymptomatic stages of Alzheimer's disease (AD) remain poorly understood. Previous research in preclinical AD shows heterogeneous findings, reporting both subtle neuronal loss and paradoxical increases in grey matter (GM) v...

Modulation of neuronal excitability and plasticity by BHLHE41 conveys lithium non-responsiveness

Abstract Many bipolar disorder (BD) patients are non-responsive to lithium. The mechanisms underlying lithium (non-)responsiveness are largely unknown. By using gene-set enrichment analysis methods, we found that core clock gene-sets are significantly associated with lithium resp...

Transcription-protein dissociation reveals disrupted cellular stress pathways in the prefrontal cortex of depression and schizophrenia subjects

Abstract Major depressive disorder (MDD) and schizophrenia (SCZ) are severe psychiatric disorders, the molecular mechanisms of which remain incompletely understood. Increasing evidence implicates neuroinflammatory signaling, autophagy dysregulation, and unfolded protein response...

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...

Incidence, prevalence, and ketoacidosis at onset of type 1 diabetes in Spain: a systematic review and critical assessment of the available evidence

The incidence, prevalence and onset of type 1 diabetes (T1D) with diabetic ketoacidosis (DKA) in Spain remain insufficiently characterized, despite multiple regional analyses. This study aims to summarize and critically assess epidemiologic data in Spain, incorporating insights f...

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....

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures

We developed a high-content screening to investigate how Alzheimer’s disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently d...

Integrated multiomics analysis reveals metabolic and microbiome alterations in Wilson disease

Wilson disease (WD) is a rare autosomal recessive disorder caused by mutations in ATP7B , which encodes a copper transporter. Abnormal ATP7B function leads to copper deposition, mainly in the liver and brain, resulting in hepatic, neurological, and psychiatric impairments. Metabo...

Key recommendations for primary care from the 2026 GOLD update

The Global Initiative for Obstructive Lung Disease (GOLD) has produced yearly recommendations for the diagnosis and management of patients with COPD since 2001. Here, we summarize the key recommendations of the GOLD 2026 document for a primary care audience, highlighting what has...

Decoding Atypical G‐Quadruplexes and Their Interactome in Liquid Biopsies via Integrated Electroanalytical–Proteomic Technologies

A multipurpose electroanalytical biotechnology to advance the role of atypical G-quadruplex (G4) structures as emerging, multifunctional DNA biomarkers is reported. The technology presented enables determination, selective isolation, and in-depth characterization of G4 motifs fro...

Cost-effectiveness of lenacapavir versus tenofovir disoproxil fumarate plus emtricitabine for pre-exposure prophylaxis to prevent HIV-1 transmission in gay, bisexual, and other men who have sex with men in Spain

Background Lenacapavir (LEN), a twice-yearly subcutaneous capsid inhibitor, has demonstrated superior efficacy over daily oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) as HIV pre-exposure prophylaxis (PrEP) in clinical trials. No European cost-effectiveness analyses...

Early evaluation of the WCT EVI MAP project: implementation, challenges, and emerging impact on evidence-based tumour classification

<ns5:p>Background The WHO Classification of Tumours (WCT) underpins cancer diagnosis globally, but the evidence-base used to inform tumour classification has never been systematically appraised. The WCT EVI MAP project was designed to address this need by developing a structured,...
