Article Synopsis
- This study looks at new helmet liners made from a special material called polyamide 12 (PA12) that can help protect against brain injuries when someone gets hit.
- The researchers tested different designs of these lattice structures and found that one design, called dode-medium, worked best in reducing damage to the brain during impacts.
- The results showed that these new liners could do a much better job than traditional foam liners, especially when it comes to protecting the brain during sideways hits.
Background & Objectives: The risk factors for clinically significant diffuse parenchymal lung abnormalities (CS-DPLA) persisting after severe coronavirus disease 2019 (COVID-19) pneumonia remain unclear. The present study was conducted to assess whether COVID-19 severity and other parameters are associated with CS-DPLA.
Methods: The study participants included patients who recovered after acute severe COVID-19 and presented with CS-DPLA at two or six month follow up and control group (without CS-DPLA).
Head-first compressive impacts occur in motorcycle crashes and may result in serious to fatal neck injuries to riders. Equipment to protect the riders' necks from these injuries are available in the market; however, their effectiveness in reducing injury risk is not clear, either due to the lack of scientific evidences or assessment with any prevalently accepted standard. This paper presents a finite element ligamentous neck model, developed as a computationally efficient tool, for future use in the computational phase of assessment process of neck protective equipment.
