AI Article Synopsis
- Motorcycle-vehicle collisions are common and often result in serious head injuries for motorcyclists, prompting this study to examine various impact scenarios and vehicle designs.
- The study analyzed five vehicle types (Sedan, MPV, SUV, EV, and 1-Box) using standardized impact angles and speeds to assess head injury risks using metrics like HIC and CSDM.
- Key findings suggest that impact speeds of around 15 m/s increase head injury risk significantly, especially at a 45° angle, while modifications to vehicle design, particularly the height of the bonnet leading edge, could help reduce this risk.
Article Abstract
Motorcycle to vehicle collision is one of the most common accidents in the world and usually leads to serious or fatal head injuries to motorcyclists. This study aims to investigate the influences of impact scenarios and vehicle front-end design parameters on head injury risk of the motorcyclist. Five general vehicle types and different impact scenarios were selected for a parametric analysis. Impact scenarios were set according to ISO, 13232 regulation considering impact angles and impact speeds. Five vehicle types of Sedan, MPV (Multi-Purpose Vehicle), SUV (Sport Utility Vehicle), EV (Electric Vehicle) and 1-Box vehicle were included. HIC (Head Injury Criterion), head angular acceleration and CSDM (Cumulative Strain Damage Measure) were calculated to evaluate head injury risk of the motorcyclist. The results show that the critical impact speed for HIC and head angular acceleration was around 15 m/s, while the critical speed for CSDM was approximately 10 m/s. Impact angle of 45° show extremely high injury risk to the motorcyclist head. Bonnet leading edge height and its combination with other parameter present high influences on motorcyclist head injuries, and the increasing the bonnet leading edge height can potentially reduce head injury risk of motorcyclists. In summary, the present research results provide some theoretic bases for determining the test speed in motorcycle-vehicle crash regulation and design consideration for typical vehicle front end shape.

Currently there are no effective treatments for an array of neurodegenerative disorders to a large part because cell-based models fail to recapitulate disease. Here we develop a reproducible human iPSC-based model where laser axotomy causes retrograde axon degeneration leading to neuronal cell death. Time-lapse confocal imaging revealed that damage triggers an apoptotic wave of mitochondrial fission proceeding from the site of injury to the soma.

Spontaneous epidural hematoma (EDH) is a rare sickle cell disease (SCD) complication. We report 3 pediatric cases with SCD and spontaneous EDH and 1 with subgaleal hematomas in the setting of vaso-occlusive crises and elaborate on their presentation and management. Through a scoping review, we identified 71 additional cases reported from 1970 to 2024 and highlighted notable features.

Background Acetabular fractures, a rising concern in developing countries, pose a significant challenge due to their complexity and association with post-operative complications. Often caused by high-energy mechanisms like falls and motor vehicle accidents, these fractures require accurate reduction to prevent long-term issues and the potential need for hip replacement. This study investigates the radiological outcomes of acetabular fracture surgery at six months, focusing on the effectiveness of achieving anatomical reduction using the Matta criteria in a low-and middle-income country (LMIC) setting.
