Acquired cystic kidney disease in children with kidney failure.

Background: This study aimed to evaluate the incidence, contributing factors, and clinical outcomes of acquired cystic kidney disease (ACKD) in children undergoing kidney replacement therapy (KRT).

Methods: We conducted a cross-sectional, territory-wide study at the designated pediatric nephrology center in Hong Kong. ACKD was defined as the presence of ≥ 3 cysts in the native kidneys, excluding congenital or hereditary cystic diseases.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Antihypertensive Deprescribing and Functional Status in VA Long-Term Care Residents With and Without Dementia.

Background: Deprescribing antihypertensives is of growing interest in geriatric medicine, yet the impact on functional status is unknown. We emulated a target trial of deprescribing antihypertensive medications compared with continued use on functional status measured by activities of daily living (ADL) in a long-term care population.

Methods: We included 12,238 Veteran Affairs long-term care residents age 65+ who had a stay ≥ 12 weeks between 2006 and 2019.

Intestinal organoid co-culture systems: current approaches, challenges, and future directions.

The intestinal microenvironment represents a complex and dynamic ecosystem, comprising a diverse range of epithelial and non-epithelial cells, a protective mucus layer, and a diverse community of gut microbiota. Understanding the intricate interplay between these components is essential for uncovering the mechanisms underlying intestinal health and disease. The development of intestinal organoids, 3D mini-intestines that closely mimic the architecture, cellular diversity, and functionality of the intestine, offers a powerful platform for investigating different aspects of intestinal physiology and pathology.

P-cadherin mechanoactivates tumor-mesothelium metabolic coupling to promote ovarian cancer metastasis.

Cancer adhesion to the mesothelium is critical for peritoneal metastasis, but how metastatic cells adapt to the biomechanical microenvironment remains unclear. Our study demonstrates that highly metastatic (HM), but not non-metastatic, ovarian cancer cells selectively activate the peritoneal mesothelium. HM cells exert a stronger adhesive force on mesothelial cells via P-cadherin, an adhesion molecule abundant in late-stage tumors.
