Centre-level fluid management practices in the BISTRO trial and their lack of association with participant fluid status and blood pressure in non-anuric haemodialysis patients.

Introduction: Fluid assessment and management is a key aspect of good dialysis care and is affected by patient-level characteristics and potentially centre-level practices. In this secondary analysis of the BISTRO trial we wished to establish whether centre-level practices with the potential to affect fluid status were stable over the course of the trial and explore if they had any residual associations with participant's fluid status.

Methods: Two surveys (S) of fluid management practices were conducted in 32 participating centres during the trial, (S1: 2017-18 and S2: 2021-22).

Expression of Wnt signaling proteins in rare congenital bladder disorders.

Introduction And Aims: Congenital bladder anomalies are rare and are a leading cause of end stage renal failure in children. The Wnt signaling pathway, important during embryonic development, has been implicated in the pathogenesis of these conditions through regulation of gene expression, including essential transcription factors. We investigated the expression of four Wnt transcriptional targets, namely, Pygopus 1 (Pygo1), Connexin 43 (Cx43), FRA1 and TCF7L1 in three rare congenital bladder disorders: bladder exstrophy (BE), neurogenic bladder (NGB) and posterior urethral valves (PUV).

British Heart Rhythm Society Standards for Implantation and Follow-up of Cardiac Rhythm Management Devices in Adults: January 2024 Update.

This updated guidance is designed to help with implantation and follow-up with agreed standards of practice. The update includes new guidance on subcutaneous defibrillators, leadless pacemakers and conduction system pacing. It includes new guidance on considerations at the time of a potential box change and techniques to be considered to minimise the risk of infection.

Differential renal length index: useful measure in management of isolated unilateral hydronephrosis?

Objective: To explore the usefulness of the 'differential renal length index' (iDRL) before and after pyeloplasty, as the anteroposterior diameter is commonly used to quantify hydronephrosis but inaccuracies arise due to interobserver variability, hydration status and pure intra-renal dilatation.

Patients And Methods: Prospectively collected data, from two centres, of all children undergoing pyeloplasty for isolated unilateral pelvi-ureteric junction obstruction (PUJO) (2015-2021) were analysed. Subgroup analysis was undertaken: Group A - differential renal function (DRF) ≥40%, Group B - subnormal DRF (20-39%), and Group C - symptomatic.

International Consensus Statement on the Radiological Evaluation of Dysraphic Malformations of the Spine and Spinal Cord.

Dysraphic malformations of the spine and spinal cord (DMSSC) represent a spectrum of common congenital anomalies typically (though not exclusively) affecting the lower spinal segments. These may be responsible for varying degrees of neurologic, orthopedic, and urologic morbidity. With advances in neuroimaging, it is now possible to better diagnose and evaluate these disorders both prenatally and postnatally.
