Schizophrenia research in 2026: report from the annual meeting of the Schizophrenia International Research Society

Abstract SIRS 2026, held under the theme “Schizophrenia Research in the Era of Artificial Intelligence,” brought together researchers, clinicians, and persons with lived experience to take stock of a field whose tools for measuring, predicting, and intervening in psychosis have e...

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...

Screening for multidrug-resistant organism: clinical benefit or unquestioned routine

PURPOSE OF REVIEW: Current strategies for multidrug-resistant organism (MDRO) screening are primarily intended to support infection prevention programs. However, accumulating evidence indicates that intestinal colonization also provides clinically relevant information for antimic...

Targeted DNA Sequencing Reveals Distinct Rare-Variant Profiles in Pulmonary Hypertension Associated with Chronic Lung Diseases

The mechanisms underlying the development and severity of pulmonary hypertension (PH) in chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) remain poorly understood. To investigate the contribution of genetic factors, we performed targeted sequencing...

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...

The NBGENS project protocol: Pilot study for genetic newborn screening in Galicia

Background Conventional newborn screening (NBS) relies on mainly biochemical assays and remains limited by its dependence on detectable biomarkers within a narrow postnatal window, leaving many treatable genetic disorders unidentified. Advances in next-generation sequencing have...

Extravasation of vesicant drugs in combined regimens: A case with a fatal outcome

Introduction Extravasation of vesicant chemotherapy is an oncological emergency that may result in severe tissue injury, functional impairment, and long-term morbidity. Management becomes particularly challenging in combination regimens containing agents with different vesicant p...

Structural and metabolic imaging after mechanical thrombectomy for acute ischemic stroke: A hybrid 18F-FDG PET/MRI pilot study

Hybrid 2-[18F]-fluoro-2-deoxy-D-glucose positron emission tomography/magnetic resonance imaging (18F-FDG PET/MRI) enables simultaneous, single-session assessment of structural and metabolic stroke damage. We prospectively studied 10 consecutive patients (6 women; mean age 71.6 ±...

Comparative analysis of maternal diet and its individual compounds in pregnancies with and without preeclampsia

Maternal diet during pregnancy may influence maternofoetal outcomes, including the occurrence of preeclampsia. The objective was to assess the association of maternal adherence to a Mediterranean diet pattern with preeclampsia, and the correlation with surrogate makers of the dis...

Mixed Epithelial Stromal Tumour of the Seminal Vesicle Presenting with Recurrent Acute Urinary Retention: A Case Report

Background: Mixed epithelial stromal tumour (MEST) is a rare biphasic neoplasm, most commonly arising in the kidney. Seminal vesicle involvement is exceedingly uncommon, and its clinical and imaging characteristics remain poorly defined. We present a rare case with detailed clini...

Viral pneumonia in older adults: from immunosenescence and chronic disease to vaccine-modifiable risk

In older adults, respiratory viral infections should not be viewed solely as isolated acute events, but as part of a broader vaccine-modifiable clinical burden shaped by immunosenescence, multimorbidity and frailty. These interconnected factors increase susceptibility to respirat...

Robot-assisted total hip arthroplasty: does improved precision translate into better clinical outcomes? A systematic review

Abstract Purpose Robot-assisted total hip arthroplasty (R-THA) is being adopted progressively because of its potential to improve implant positioning and restore hip biomechanics more accurately than conventional techniques. However, whether these technical advantages translate i...

Mental health disparities in LGBTQIA+ populations: an umbrella review of systematic reviews and meta-analyses.

Lesbian, gay, bisexual, transgender, questioning, intersex, asexual (LGBTQIA+) populations face unique social, political, psychological and health care-related challenges that contribute to marked mental health disparities. However, the overall strength and credibility of evidenc...

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...

Timing and trajectory of acute kidney injury predict mortality in alcohol-associated hepatitis: A multinational cohort study.

BACKGROUND: Acute kidney injury (AKI) is common in alcohol-associated hepatitis (AH) and associated with poor outcomes, yet the prognostic implications of AKI timing and early renal trajectory remain unclear. METHODS: In this prospective multicenter cohort from the Global AlcHep...

Phytate and L-methionine for preventing recurrence of infection renal stones

BACKGROUND: Urine acidification and inhibition of crystallization are strategies that can be employed to prevent recurrent infection stones and calcium phosphate stones. METHODS: A series of cases demonstrating the beneficial effects of treatment with phytate and L-methionine in...

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...

Standards for practical management of drug hypersensitivity reactions to intravenous drugs and proactive early allergy involvement before referral: A WAO Statement

Hypersensitivity reactions to intravenous therapies—including antibiotics, chemotherapeutics, biologics, anesthesia agents, and contrast media—pose significant challenges in acute care settings. These reactions often occur outside the purview of allergy specialists, leading to de...

Cognitive vergence and pupil response during oddball task are associated with Alzheimer´s disease cerebrospinal fluid neurodegenerative biomarkers

Alzheimer’s disease (AD) can be diagnosed using cerebrospinal fluid (CSF) biomarkers reflecting amyloid and tau pathology. However, they provide no information about functional network status. We aimed to determine whether CSF biomarkers (Aβ42, p-Tau, t-Tau, and Aβ42/p-Tau ratio)...

A framework for outcome determination of nosocomial pneumonia treatment in ventilated critically ill patients

Abstract Background Treatment failure of hospital-acquired (HAP) and ventilator-associated pneumonia (VAP) is a common endpoint in clinical research, yet the absence of a reproducible definition hampers comparability across studies. We propose an operational framework for assessi...
