Changes in Bile Acid Metabolism and Nutrient-Stimulated Hormone Responses After Malabsorptive Metabolic Surgery: RYGB Versus SADI-S

Background/Objectives: Bariatric–metabolic surgery (BMS) improves obesity through neuroendocrine mechanisms involving bile acids (BAs) and nutrient-stimulated gastrointestinal hormones. However, the underlying pathophysiology involved remains poorly understood. BAs are essential...

Validating Type 2 Diabetes Diagnoses Across the Madrid Hospital Network: Evidence for Secondary Use of the CMBD in the European Health Data Space

Background/Objectives: Hospital discharge data are increasingly reused for research and within health data spaces, but their value depends on accurate diagnostic coding. The validity of type 2 diabetes mellitus (T2DM) coding in the Spanish hospital discharge database (CMBD) had n...

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...

Urinary Hypaphorine as a Candidate Marker of FFQ-Derived Legume Intake Within the EAT-Lancet Framework in Free-Living Adults

Dietary assessment is affected by recall, reporting, portion-size error, and food-composition inconsistencies. Hypaphorine, a tryptophan-derived betaine alkaloid found in pulses and other foods, has been proposed as a marker of legume exposure, but its performance in free-living...

Lignans as a Potential Metabolomic Biomarker for Nut Consumption and EAT-Lancet Diet Score Adherence

Abstract Metabolomic biomarkers may represent reliable objective measurements and can be useful for assessing dietary intake and avoiding biases. The objective of this study is to identify novel metabolomic indicators of dietary patterns. Dietary, anthropometric, blood biomarkers...

Hypertension in obesity: A focus on individualized pharmacotherapy and the role of body composition, on behalf of the European Society of Hypertension Working Group on Diabetes and Metabolic Risk Factors and Working Group on Lifestyle, Cardiovascular Pharmacotherapy and Adherence

Hypertension in obesity represents a major global health challenge, closely linked to the global epidemics of obesity, type 2 diabetes and metabolic dysfunction. Excess adiposity contributes to elevated blood pressure through multiple, interrelated mechanisms, including activatio...

Severity of Reactions in Double-Blind Placebo-Controlled Food Challenges: New Insights From the EuroPrevall Outpatient Clinic Study

BACKGROUND AND OBJECTIVES: Oral food challenge, particularly double-blind placebo-controlled food challenge (DBPCFC), is the gold standard for diagnosis of food allergy, although safety concerns limit its widespread use. Objectives: To evaluate the severity of reactions during DB...

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...

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...

Bioprosthetic Valve Failure After Transcatheter Aortic Valve Replacement

BACKGROUND: Data on the long-term incidence and clinical impact of bioprosthetic valve failure (BVF) after transcatheter aortic valve replacement remain limited. This study aimed to assess the incidence, predictors, and clinical impact of BVF following transcatheter aortic valve...

Mitochondrial bioenergetic remodeling underlies fingolimod-induced immunometabolic adaptation in multiple sclerosis

Mitochondrial dysfunction and immune cell metabolic reprogramming are central mechanisms driving the pathogenesis and progression of multiple sclerosis (MS). Fingolimod (FTY720), a sphingosine-1-phosphate analog widely used in MS, limits lymphocyte egress from lymphoid organs; ho...
