Early-Start vs. Late-Start Icodextrin for Children Receiving Chronic Peritoneal Dialysis: Findings from the International Pediatric Peritoneal Dialysis Network.

Background: Experience with icodextrin use in children on long-term peritoneal dialysis is limited. We describe international icodextrin prescription practices and their impact on clinical outcomes: ultrafiltration, blood pressure control, residual kidney function (RKF), technique and patient survival.

Methods: We included patients under 21 years enrolled in the International Pediatric Peritoneal Dialysis Network (IPPN) between 2007 and 2024, on automated PD with a daytime dwell.

Recessive TMEM167A variants cause neonatal diabetes, microcephaly and epilepsy syndrome.

Understanding the genetic causes of diseases affecting pancreatic β cells and neurons can give insights into pathways essential for both cell types. Microcephaly, epilepsy and diabetes syndrome (MEDS) is a congenital disorder with two known aetiological genes, IER3IP1 and YIPF5. Both genes encode proteins involved in endoplasmic reticulum (ER) to Golgi trafficking.

Neural correlates of Bayesian social belief updating in the medial prefrontal cortex.

Social learning, a hallmark of human behavior, entails integrating other's actions or ideas with one's own. While it can accelerate the learning process by circumventing slow and costly individual trial-and-error learning, its effectiveness depends on knowing when and whose information to use. In this study, we explored how individuals use social information based on their own and others' levels of uncertainty.

Giant mobility of surface-trapped ionic charges following liquid tribocharging.

The sliding motion of aqueous droplets on hydrophobic surfaces leads to charge separation at the trailing edge, with implications from triple-line friction to hydrovoltaic energy generation. Charges deposited on the solid surface have been attributed to ions or electrons ripped off from the liquid drop. However, the dynamics and exact physicochemical nature of these surface-trapped charges remains poorly explored.

Excitatory glycine receptors control ventral hippocampus synaptic plasticity and anxiety-related behaviors.

Excitatory glycine receptors (eGlyRs), composed of the glycine-binding NMDA receptor subunits GluN1 and GluN3A, have recently emerged as a novel neuronal signaling modality that challenges the traditional view of glycine as an inhibitory neurotransmitter. Unlike conventional GluN1/GluN2 NMDARs, the distribution and role of eGlyRs remain poorly understood. Here, we show that eGlyRs are highly enriched in the ventral hippocampus (VH) and confer distinct properties on this brain region.

From molecular damage and viscoelasticity to interfacial fracture in soft polymer networks: Insights from mechanochemistry.

Many soft, tough materials have emerged in recent years, paving the way for advances in wearable electronics, soft robotics, and flexible displays. However, understanding the interfacial fracture behavior of these materials remains a significant challenge, owing to the difficulty of quantifying the respective contributions from viscoelasticity and damage to energy dissipation ahead of cracks. This work aims to address this challenge by labeling a series of polymer networks with fluorogenic mechanophores, subjecting them to T-peel tests at various rates and temperatures, and quantifying their force-induced damage using a confocal microscope.

Synovial MS4A4A correlates with inflammation and counteracts response to corticosteroids in arthritis.

MS4A4A belongs to the MS4A tetraspan protein superfamily and is selectively expressed by the monocyte-macrophage lineage. In this study, we aimed to evaluate the role of MS4A4A+ macrophages in rheumatoid arthritis (RA) pathogenesis and response to treatment. RNA sequencing and immunohistochemistry of synovial samples from either early treatment-naïve or active chronic RA patients showed that MS4A4A expression positively correlated with synovial inflammation.

Morphometric study of bioprinted hydrogel deformation during histological preparation.

Histological preparation paraffin embedding is the gold standard method for evaluating tissue structure and composition, whether it is originated from biopsy or engineered . Quite often, deformation and shrinkage occur during the histological preparation, which are difficult to predict and qualify. The present study investigates the morphometric changes in bioprinted hydrogels composed of alginate and gelatine, common tissue engineering materials, focusing on three morphologies: full slabs, porous slabs, and porous cubes.

Essentials of the System of Radiological Protection.

The System of Radiological Protection (the "System") developed by the International Commission on Radiological Protection (ICRP) is built on nearly a century of efforts of numerous scientists and practitioners working together internationally. It rests on three enduring pillars: science, ethics, and experience. These pillars support the three fundamental principles that shape radiological protection strategies: justification, optimisation, and application of dose limits.

Impact of weight classes on feasibility, safety, and efficacy of awake craniotomy for brain lesions within eloquent areas.

Awake craniotomy is the gold standard to achieve maximal safe resection of brain lesions located within eloquent areas. There are no established guidelines to assess patient's eligibility for awake craniotomy by weight class. This study assesses feasibility, safety, and efficacy of awake surgery by weight classes through an observational, retrospective, single-institution cohort analysis (2010-2024) of 526 awake craniotomies.

MetabOCT: a clinical trial looking for a metabolomic signature predicting the onset of Leber's hereditary optic neuropathy in healthy MtDNA mutations carriers.

Introduction: The definition of Leber's hereditary optic neuropathy (LHON) does not take into account a preclinical phase during which the thickness of retinal nerve fiber layer (RNFL) is increased, prior to optic nerve atrophy, reducing the chances of visual recovery.

Objectives: Search for a metabolomic signature characterizing this preclinical phase and identify biomarkers predicting the risk of LHON onset.

Methods And Results: The blood and tear metabolomic profiles of 90 asymptomatic LHON mutation carriers followed for one year will be explored as a function of RNFL thickness and compared to those of a healthy control.

Evaluation of the Analgesia Nociception Index (ANI) as an indicator of discomfort in deeply sedated, prepubescent patients.

The Analgesia Nociception Index (ANI) has been used to assess discomfort in anesthetized adults. The COMFORT Behavior Scale (CBS) is recommended for assessing discomfort in intubated and sedated children. The primary objective of the present study was to assess the validity and performance of the ANI as an indicator of discomfort in intubated, ventilated children in a pediatric intensive care unit (PICU).

The hidden pandemic: changes in outpatient mental health care among French children and adolescents.

The COVID-19 pandemic significantly worsened mental health (MH) challenges among young people. We aimed to assess changes in mental health-related outpatient care before and after the onset of the pandemic. In this nationwide cross-sectional study, we retrieved visits to general practitioners (GP) resulting in the coding of a MH disorder and/or the prescribing of any psychotropic medication for children aged 6 to 17 years, from January 1, 2016 to May 31, 2022 in France.

Individual alpha frequency tACS modifies the detection of space-time optical illusion.

Postdiction is a perceptual phenomenon where the perception of an earlier stimulus is influenced by a later one. This effect is commonly studied using the 'rabbit illusion', in which temporally regular, but spatially irregular, stimuli are perceived as equidistant. While previous research has focused on short inter-stimulus intervals (100-200 ms), the role of longer intervals, which may engage late attentional processes, remains unexplored.

Management of renal cancer with inferior vena cava extension over 30 years: a bi-centric study.

Purpose: In 5-10% of cases, renal cancer extends into the venous system, particularly the inferior vena cava (IVC), which worsens prognosis. This study aims to assess morbidity, mortality, and oncological outcomes of patients treated surgically for renal cancer with IVC extension over a 30-year period, in two experienced centers.

Materials And Methods: This bicentric, retrospective study analyzed patients treated between 1988 and 2020 for renal cancer involving the IVC.

Transposing intensive care innovation from modern warfare to other resource-limited settings.

Background: Delivering intensive care in conflict zones and other resource-limited settings presents unique clinical, logistical, and ethical challenges. These contexts, characterized by disrupted infrastructure, limited personnel, and prolonged field care, require adapted strategies to ensure critical care delivery under resource-limited settings.

Objective: This scoping review aims to identify and characterize medical innovations developed or implemented in recent conflicts that may be relevant and transposable to intensive care units operating in other resource-limited settings.

Aims/hypothesis: Severe hypoglycaemia events (SHE) remain frequent in people with type 1 diabetes despite advanced diabetes technologies. We examined whether time below range (TBR) 3.9 mmol/l (70 mg/dl; TBR70) or 3.

Adults with Autism Have Numerous Needs, and So Do Their Parents!

Parents of adults with autism spectrum disorders (ASD) face significant challenges, including high vulnerability to stress and a lack of adequate support services. However, there are currently few support systems based on a genuine assessment of their needs. This is particularly true in the French context, where there are delays in supporting families and addressing autism in adulthood.

Collisional Excitation of HCN by CO to Refine the Modeling of Cometary Comae.

We present the first dataset of collisional (de)-excitation rate coefficients of HCN induced by CO, one of the main perturbing gases in cometary atmospheres. The dataset spans the temperature range of 5-50 K. It includes both state-to-state rate coefficients involving the lowest ten and nine rotational levels of HCN and CO, respectively, and the so-called "thermalized" rate coefficients over the rotational population of CO at each kinetic temperature.
