Efficacy of immune checkpoint inhibitors in renal cell carcinoma venous tumour thrombus shrinkage (UroCCR 128).

Purpose: Surgery remains the cornerstone of localized renal cell carcinoma (RCC) care. Pembrolizumab has recently been recommended as a standard of care for RCC patients who are at high risk of recurrence. Data regarding the efficacy of ICIs either alone or in combination with ICIs or VEGF TKIs for VTT shrinkage are scarce.

AntiBody Sequence Database.

Antibodies play a crucial role in the humoral immune response against health threats, such as viral infections. Although the theoretical number of human immunoglobulins is well over a trillion, the total number of unique antibody protein sequences accessible in databases is much lower than the number found in a single individual. Training AI (Artificial Intelligence) models, for example to assist in developing serodiagnoses or antibody-based therapies, requires building datasets according to strict criteria to include as many standardized antibody sequences as possible.

Dynamic NMR Relaxometry as a Straightforward Measurement of Concentration Variations in Colloidal Gels.

We show that dynamic NMR relaxometry allows one to probe the particle size or the concentration evolution over time in homogeneous colloidal suspensions or the concentration in different regions of heterogeneous suspensions, up to large volume fractions. We first demonstrate that the NMR transverse relaxation time is independent of the gel structure at the particle scale so that it only slightly varies during the gelation of a colloidal suspension. The evolution over time of the NMR transverse relaxation time during gel drying and its analysis with the help of the fast-exchange assumption extended to a partially saturated medium then allowed us to identify three successive regimes: homogeneous shrinkage, desaturation, and molecular film regime.

Long-term effects of sirolimus treatment for slow-flow vascular malformations: Real-world evidence from the French observational multicentre SIROLO study.

Rationale: Sirolimus is a treatment for slow-flow vascular malformations (SFVMs). However, the long-term management remains challenging.

Objectives: The SIROLO study assessed the long-term effects and real-life management of oral sirolimus for SFVMs by investigating data from 15 French tertiary centres for vascular anomalies.

Safety and efficacy of human umbilical cord-derived mesenchymal stromal cells in fetal ovine myelomeningocele repair.

Background: The aim of this study was to assess the safety and efficacy of human umbilical cord mesenchymal stromal cells (hUC-MSCs) patch used as an adjuvant therapy in fetal myelomeningocele (MMC) surgery in the ovine model.

Methods: hUC-MSCs were isolated from human umbilical cords (UC) using the explant method, cultured and characterized. hUC-MSCs were then embedded in a fibrin patch.

[Association between iron deficiency and risk of major events in chronic kidney disease].

Introduction: Iron deficiency (ID) is common in patients with chronic kidney disease (CKD) but remains under-diagnosed and its prognosis poorly documented in the absence of anemia. The aim of the study was to assess the relationship between ID and the risk of major adverse outcomes in patients with CKD.

Methods: Using data from the French Chronic Kidney Disease - Renal Epidemiology and Information Network (CKD-REIN) cohort which included and followed over five years, 3,033 patients with CKD stages 2 to 5 CKD, we estimated the prevalence of ID, defined by a ferritin level < 100 μg/L and/or a transferrin saturation < 20%, and associated hazard ratios (HR) of kidney failure with replacement therapy, kidney failure defined by an eGFR < 15 mL/min per 1.

Evaluating risks, monitoring cannabis use, and planning to get home safely: Exploring self-regulation processes associated with cannabis use and driving.

Objective: Preventing Cannabis-impaired driving involves understanding how users assess risk, monitor their use, and plan to get home safely. While extant research has shown substantial heterogeneity in patterns of cannabis use among different user groups, far less research has examined self-regulation among users. The current study aims to identify sub-groups of individuals who used or have used cannabis based on how they perceive risks, monitor their impairment, and plan to avoid driving under the influence of cannabis (DUIC) to examine how the different profiles relate to DUIC outcomes.

Reflective Tool on Advanced Access to Support Primary Healthcare Teams: Development and Validation of an Online Questionnaire.

Rationale: Awareness of their standing relative to best practices motivates primary healthcare (PHC) teams to improve their practices. However, gathering the data necessary to create such a portrait is a challenge. An effective way to support the improvement of the practices of PHC teams is to simplify the availability of data portraying aspects of their practices that might need improvement.

Bridging the gap: Exploring consumer experiences and motivations for transitioning between illicit and regulated cannabis markets.

Background: Canada pioneered the non-medical legalization of cannabis production and sales, witnessing substantial growth in the regulated market over the last five years, post-legalization. However, persistent barriers hinder many consumers from transitioning to the legal market, necessitating a nuanced understanding of their behaviors for targeted policy interventions. This study aims to improve understanding of cannabis consumers' unregulated purchase decisions in British Columbia (B.

Atypical rhizobia trigger nodulation and pathogenesis on the same legume hosts.

The emergence of commensalism and mutualism often derives from ancestral parasitism. However, in the case of rhizobium-legume interactions, bacterial strains displaying both pathogenic and nodulation features on a single host have not been described yet. Here, we isolated such a bacterium from Medicago nodules.

Synergistic effect between denosumab and immune checkpoint inhibitors (ICI)? A retrospective study of 268 patients with ICI and bone metastases.

Background: Bone metastasis is a significant concern in advanced solid tumors, contributing to diminished patient survival and quality of life due to skeletal-related events (SREs). Denosumab (DMAB), a monoclonal antibody targeting the receptor activator of nuclear factor kappa-B ligand (RANKL), is used to prevent SREs in such cases. The RANK/RANKL axis, crucial in immunological processes, has garnered attention, especially with the expanding use of immune checkpoint inhibitors (ICI) in modern oncology.

Role of Amniotic Fluid Toxicity in the Pathophysiology of Myelomeningocele: A Narrative Literature Review.

Myelomeningocele is a birth defect whose clinical manifestations are due both to incomplete neural tube closure and the progressive destruction of exposed neuroepithelium during pregnancy. Two hypotheses have been formulated to explain the spinal cord damage in utero: mechanical trauma and chemical factors. The objective of this review was to summarize the current insights about the potential role of amniotic fluid in spinal cord damage in myelomeningocele.

Co-creation and evaluation of an algorithm for the development of a mobile application for wound care among new graduate nurses: A mixed methods study.

Chronic wounds are a growing concern due to aging populations, sedentary lifestyles and increasing rates of obesity and chronic diseases. The impact of such wounds is felt worldwide, posing a considerable clinical, environmental and socioeconomic challenge and impacting the quality of life. The increasing complexity of care requires a holistic approach, along with extensive knowledge and skills.

Crystallographic Dependence of Field Evaporation Energy Barrier in Metals Using Field Evaporation Energy Loss Spectroscopy Mapping.

Atom probe tomography data are composed of a list of coordinates of the reconstructed atoms in the probed volume. The elemental identity of each atom is derived from time-of-flight mass spectrometry, with no local chemical information readily available. In this study, we use a data processing technique referred to as field evaporation energy loss spectroscopy (FEELS), which analyzes the tails of mass peaks.

[Metastatic castration-resistant prostate cancer and PARP inhibitors: From tumor genomics to new therapeutic combinations].

Castration-resistant metastatic prostate cancer remains lethal and a therapeutic challenge. Current strategies are geared towards the personalization of treatments based on the identification of relevant molecular targets, including genomic alterations involved in tumoral processes. Among these novel targeted therapies, poly-ADP-ribose polymerase inhibitors (PARPi), by blocking the action of enzymes involved in deoxyribonucleic acid (DNA) repair, induce the destruction of cells carrying defects in homologous recombination repair, often associated with alterations in genes involved in this mechanism.

Alternating between even and odd ploidy levels switches on and off the recombination control, even near the centromeres.

Meiotic recombination is a key biological process in plant evolution and breeding, as it generates genetic diversity in each generation through the formation of crossovers (COs). However, due to their importance in genome stability, COs are highly regulated in frequency and distribution. We previously demonstrated that this strict regulation of COs can be modified, both in terms of CO frequency and distribution, in allotriploid Brassica hybrids (2n = 3x = 29; AAC) resulting from a cross between Brassica napus (2n = 4x = 38; AACC) and Brassica rapa (2n = 2x = 20; AA).

Association Between EHR Compatibility and Nurses' Emotional Exhaustion.

In this study we explored the relationship between nurses' emotional exhaustion and three EHR compatibility subdimensions (nurses' preferred work style, existing clinical practice, and values). We found higher emotional exhaustion with lower EHR compatibility for both preferred work style and existing clinical practice, but no relationship between emotional exhaustion and nurses' values. Efforts to improve EHR compatibility are recommended to mitigate nurses' burnout.

Development and Testing of an Instrument to Measure the Impact of EHR Use on Quality of Care.

There is an increased adoption of electronic health records (EHR) motivated by many purported benefits, yet limited research has explored their impact on quality of care. We developed and tested a multidimensional measure of quality of care in relation to EHR use. 234 nurses completed a cross-sectional survey.
