Ilio-femoral impingement angle: a new radiographic measurement.

Background: Hip dislocations after total hip arthroplasty (THA) are a debilitating complication, often occurring in deep flexion. Current 3D modelling allows for simulating the flexion angle at which bone-on-bone impingement occurs, but it is resource-intensive and not widely available for routine clinical use. Therefore, we propose the ilio-femoral impingement angle (IFIa) as a novel, simple radiographic measure to help identify patients at higher risk for dislocation using standard radiographs.

The plasma metabolome of juvenile idiopathic arthritis varies according to subtype and underlying inflammatory status.

Background: Juvenile idiopathic arthritis (JIA) is challenging to classify and effectively monitor due to the lack of disease- and subtype-specific biomarkers. A robust molecular signature that tracks with specific JIA features over time is urgently required, and targeted plasma metabolomics may reveal such a signature. The primary aim of this study was to characterise the differences in the plasma metabolome between JIA patients and non-JIA controls and identify specific markers of JIA subtype.

Feed additives for methane mitigation: Modeling the impact of feed additives on enteric methane emission of ruminants-Approaches and recommendations.

Over the past decade, there has been considerable attention on mitigating enteric methane (CH) emissions from ruminants through the utilization of antimethanogenic feed additives (AMFA). Administered in small quantities, these additives demonstrate potential for substantial reductions of methanogenesis. Mathematical models play a crucial role in comprehending and predicting the quantitative impact of AMFA on enteric CH emissions across diverse diets and production systems.
