Mesenchymal stem cells as cellular factories for targeted P2X7 blockade after traumatic brain injury

Abstract Background Traumatic brain injury (TBI) causes long‐term disability, with inflammation contributing to both primary and secondary brain damage. Extracellular adenosine triphosphate (ATP) and its receptor purinergic receptor X7 (P2X7) drive neuroinflammation and represent...

Building a One Health mobile laboratory workforce: strengthening public health preparedness across Europe and Africa

Abstract The emergence and re-emergence of infectious diseases remain a major public health threat in Europe. The Horizon Europe-funded MOBILISE project addresses this challenge by establishing a One Health Mobile Laboratory capable of handling risk group 3 and 4 pathogens, while...

Efficacy of dolutegravir or bictegravir-containing therapy in a real-life cohort of people with HIV-1 sub-subtype A6

OBJECTIVE: The objective of the study was to establish whether HIV-1 sub-subtype A6 (HIV-1A6) is a risk factor for virological failure in people with HIV (PWH) treated with the high genetic barrier integrase strand transfer inhibitors (INSTIs) dolutegravir (DTG) or bictegravir (B...

Human cortical networks trade communication efficiency for computational reliability

Brains are often described as cost-efficient communication networks, optimally balancing the cost of long connections with the benefits of fast communication. Here, inspired by the "use it or lose it" principle, we present a novel game-theoretic model of self-organizing neural un...

Tricuspid-Valve Intervention in Heart Failure

BackgroundThe effect of transcatheter tricuspid-valve repair on clinical outcomes, including death and hospitalization for heart failure, in patients with severe tricuspid regurgitation remains uncertain. MethodsWe randomly assigned patients with symptomatic severe tricuspid regu...

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...

Robotic-assisted compartmental dissection for retroperitoneal sarcoma: a feasibility study on cadavers with the da Vinci Xi system

Abstract Purpose Retroperitoneal sarcomas (RPS) pose major technical challenges because of their size, anatomical complexity, and need for multivisceral resection. We evaluated the feasibility of a standardized robotic approach for right- and left-sided retroperitoneal sarcoma (R...

The Molecular Architecture of Somatic Spines of the Lateral Septum

ABSTRACT The lateral septum is a key subcortical structure and has been implicated in social memory. One aspect of social memory, the ability to recognize relatives, is conserved across vertebrate species and reflected in stable, lifelong memories. Synapses are considered to be t...

Metacognitive Training for Negative Symptoms (MCT-Minus) in schizophrenia: study protocol for a pragmatic randomized controlled trial

Abstract Background Negative symptoms are experienced by up to 60% of the individuals with schizophrenia and represent a stronger indicator of current and future functioning than positive symptoms. These symptoms respond poorly to pharmacological and existing psychosocial interve...

Pediatric intensive care follow-up in Germany is rarely established and highly heterogeneous: a nationwide survey of 20 PICUs

BACKGROUND: Survival after pediatric critical illness has improved substantially, but many survivors and their families experience long-term physical, neurocognitive, psychological and social sequelae, summarized as post-intensive care syndrome in pediatrics and in families. Stru...

Prediction of Treatment Benefit With Internet-Based Cognitive Behavioral Therapy for Depression

Importance Treatment benefit prediction models may help identify which patients will benefit most from internet-based cognitive behavioral therapy (iCBT) for depression; it is unclear whether such models can support useful treatment allocation across programs. Objective To develo...

Learning curve and target-based accuracy of diode laser versus scalpel incisions in a porcine skin model: a preclinical feasibility study with undergraduate dental students

PURPOSE: Despite the growing clinical application of diode lasers in oral surgery, laser training remains underrepresented in dental curricula. This study evaluated the feasibility of structured preclinical diode-laser training and characterized the early learning curve of underg...

State-dependent binding of the wedge domain controls inactivation of the mechanosensitive ion channel PIEZO1

Abstract The mechanically activated ion channel PIEZO1 transduces membrane tension into intracellular calcium signals and is critical for a wide range of physiological processes. Recent structural and functional studies have established a detailed framework for PIEZO1 activation,...

Daratumumab, lenalidomide, and dexamethasone in transplant-ineligible newly diagnosed multiple myeloma: MAIA final survival analysis

Abstract In previous analyses of MAIA, daratumumab plus lenalidomide/dexamethasone (D-Rd) significantly improved progression-free survival and overall survival (OS) versus lenalidomide/dexamethasone (Rd) in transplant-ineligible newly diagnosed multiple myeloma (NDMM). We report...

The clinical and molecular spectrum of AGO2-associated Lessel-Kreienkamp neurodevelopmental syndrome

Abstract Background Pathogenic variants in AGO2 ,encoding a central component of the RNA-induced silencing complex (RISC), cause the neurodevelopmental disorder Lessel-Kreienkamp syndrome (LESKRES). The variant spectrum and associated molecular mechanisms underlying phenotypic va...

Parent Mental Health From Preterm Birth Through the NICU Stay

OBJECTIVES: Preterm birth and neonatal intensive care unit (NICU) admission are not only extremely stressful for the infant itself but can also impact parental mental health. This Dutch national prospective cohort study aimed to describe the trajectory of parental mental health f...

Task-irrelevant stimuli robustly drive phasic pupil-linked arousal but only weakly affect memory formation

Abstract Brainstem arousal systems including the locus coeruleus noradrenaline system, respond transiently to behaviorally relevant events. This also drives dilations of the pupil, which are often observed during cognitive tasks. The strength of pupil responses during encoding of...

A Systematic Review and Meta-Analysis on 30-Day Readmission Rates After Endovascular Abdominal Aortic Aneurysm Repair and Open Repair

AIM: Endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) are established treatments for abdominal aortic aneurysm (AAA). This meta-analysis evaluated 30-day readmission, patient characteristics, postoperative complications, and length of stay after EVAR and OAR, an...

CMR-based aortic stiffness parameters in a symptomatic high risk obstructive sleep apnea cohort: results from the population-based Hamburg City Health Study

Abstract Background Aortic stiffness (AS) parameters as pulse wave velocity (PWV), aortic distensibility of the ascending and descending aorta (AD AoAsc, AD AoDesc) and pulse pressure (PP) are marker for vascular ageing, whereas data concerning obstructive sleep apnea (OSA) in po...

Technical note: reconstructing dose distributions from manually planned electron boosts in breast radiotherapy

Purpose In breast radiotherapy, delivery of manually-calculated electron boosts limits retrospective dose–response analyses as dose distribution is unavailable. This work evaluates the feasibility of reconstructing dose distributions from manually planned electron boosts in breas...
