Background: Despite a wide range of available treatments, there is limited evidence as to why significant numbers of Crohn's disease (CD) patients do not achieve disease remission or continue to have residual symptom burden. We aimed to quantify the impact of this suboptimal treatment on patient symptom incidence and severity, quality of life (QoL), and work impairment.

Methods: Data were derived from the Adelphi Real World CD Disease Specific Programme, a cross-sectional survey of CD patients and their treating physicians in France, Germany, Italy, Spain, the United Kingdom, and the United States between January 2020 and March 2021.

The gold standard assay for radiation response is the clonogenic assay, a normalized colony formation assay (CFA) that can capture a broad range of radiation-induced cell death mechanisms. Traditionally, this assay relies on two-dimensional (2D) cell culture conditions with colonies counted by fixing and staining protocols. While some groups have converted these to three-dimensional (3D) conditions, these models still utilize 2D-like media compositions containing serum that are incompatible with stem-like cell models such as brain tumor initiating cells (BTICs) that form self-aggregating spheroids in neural stem cell media.

Purpose: Current radiotherapy (RT) in glioblastoma (GBM) is delivered as constant dose fractions (CDF), which do not account for intratumoral-heterogeneity and radio-selection in GBM. These factors contribute to differential treatment response complicating the therapeutic efficacy of this principle. Our study aims to investigate an alternative dosing strategy to overcome radio-resistance using a novel longitudinal radiation cytotoxicity assay.

Aims: Suboptimal treatment indicators, including treatment switch, are common among patients with Crohn's disease (CD), but little is known about their associated healthcare resource utilization (HRU) and costs. This study assessed the impact of suboptimal treatment indicators on HRU and costs among adults with CD newly treated with a first-line biologic.

Methods: Adult patients with CD were identified in the IBM MarketScan Commercial Subset (10/01/2015-03/31/2020).

Autosomal dominant polycystic kidney disease (ADPKD) is a genetic kidney disease with high phenotypic variability. Furthering insights into patients' ADPKD progression could lead to earlier detection, management, and alter the course to end stage kidney disease (ESKD). We sought to identify patients with rapid decline (RD) in kidney function and to determine clinical factors associated with RD using a data-driven approach.
