Keep Moving: Sustainability of an Early Mobility Protocol in an Academic Pediatric ICU.

Introduction: Mobilization protocols are safe and feasible for critically ill pediatric patients in the intensive care unit (ICU), but barriers exist to sustainability. This study described a focused early mobility protocol, sustained over 5 years, which is on time for therapy consults and patient mobilization at a single institution.

Methods: A formal ICU mobility protocol was implemented as part of a unit-wide ICU liberation bundle.

Cellular cartography reveals mouse prostate organization and determinants of castration resistance.

Inadequate response to androgen deprivation therapy (ADT) frequently arises in prostate cancer, driven by cellular mechanisms that remain poorly understood. Here, we integrated single-cell RNA sequencing, single-cell multiomics, and spatial transcriptomics to define the transcriptional, epigenetic, and spatial basis of cell identity and castration response in the mouse prostate. Leveraging these data along with a meta-analysis of human prostates and prostate cancer, we identified cellular orthologs and key determinants of ADT response and resistance.

ImageDoubler: image-based doublet identification in single-cell sequencing.

Single-cell sequencing provides detailed insights into individual cell behaviors within complex systems based on the assumption that each cell is uniquely isolated. However, doublets-where two or more cells are sequenced together-disrupt this assumption and can lead to potential data misinterpretations. Traditional doublet detection methods primarily rely on simulated genomic data, which may be less effective in homogeneous cell populations and can introduce biases from experimental processes.

Covalently Cross-Linked Polyelectrolyte Complex Nanoparticles with Enhanced Stability against Dissociation at High Ionic Strength.

Polyelectrolyte complex nanoparticles (PECNPs) often fully dissociate into individual polycations (PC) and polyanions (PA) at high salinities. Herein, we introduce a novel type of colloidally stable PECNP in which the PC is cross-linked, in this case branched polyethylenimine (PEI) to limit this dissociation, even in solutions up to 5.2 M NaCl or 5.

Assessing flexible ureteroscopy outcomes for lower Pole versus non lower Pole stones using the flexible and navigable suction ureteric access sheath: a prospective multicenter study by EAU Endourology and PEARLS group.

Purpose: Use of suction in flexible ureteroscopy is increasing lately. The introduction of flexible and navigable suction access sheath (FANS) has shown improved stone free rate (SFR). However, its efficacy in lower pole stone (LPS) in terms of SFR and complications is yet to be studied.
