People from refugee and migrant backgrounds often face poor experiences and outcomes in healthcare, and genetic healthcare is no exception. Understanding whether and how these health inequities manifest is an important step towards equitable perinatal genetic screening for genetic or chromosomal conditions (offered preconception, prenatally, or during the newborn period). A scoping review was conducted to review international evidence of perceptions and experiences of perinatal genetic screening for people from migrant and refugee backgrounds.

Purpose: Supersaturated formulations have been widely explored for improving the oral bioavailability of drugs by using mesoporous silica (MS) to generate supersaturation via molecular adsorption; however, this is followed by precipitation. Several precipitation inhibitors (PI) have been explored to prevent precipitation and maintain the drug in solution for a longer period. However, the combined approach of MS and PIs, the impact of MS and Silica, and the loading of high-molecular-weight neutral molecules such as Cyclosporine A (CsA) have not yet been explored.

Objective: Malalignment following cervical spine deformity (CSD) surgery can negatively impact outcomes and increase complications. Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

Introduction: Quality assurance (QA) in medical imaging ensures consistently high-quality images at acceptable radiation doses. However, the applicability of the chest X-ray (CXR) QA tool in images with pathology, particularly infectious diseases like COVID-19, has not been explored. This study examines the utility of the European Guidelines for image quality in QA of CXRs with varying severity and types of infectious disease.

Article Synopsis
  • The study evaluated low-stress resin-based composites (RBCs) and their stress relaxation mechanisms, comparing them to an experimental low-stress thiourethane (TU) material.
  • The experimental composites included a mix of different dimethacrylates and barium aluminosilicate filler, with tests on polymerization kinetics and stress relaxation conducted using advanced analytical techniques.
  • Results indicated that TU-modified RBCs exhibited significantly higher polymerization conversion rates and stress reduction capabilities compared to traditional materials, with the TU composites and SDR Flow+ showing the most effective stress relaxation.
