Published studies investigating the role of driver sleepiness in road crashes in low and middle-income countries have largely focused on heavy vehicles. We investigated the contribution of driver sleepiness to four-wheel motor vehicle crashes in Fiji, a middle-income Pacific Island country. ⋯ Driver sleepiness is an important contributor to injury-involved four-wheel motor vehicle crashes in Fiji, highlighting the need for evidence-based strategies to address this poorly characterised risk factor for car crashes in less resourced settings.

Trauma is one of the major causes of morbidity and mortality. Thoracic injuries are associated with inflammatory complications such as ARDS. The pathogenesis of this complication after pulmonary injury is incompletely understood, but neutrophils are thought to play a pivotal role. The aim of this project was to gain more insight in the role of thoracic injuries in the pathophysiological processes that link systemic neutrophil activation with inflammatory complications after trauma. ⋯ Penetrating thoracic trauma leads to a distinct primed activation status of circulating neutrophils within hours. In addition to activation of cells, both young and reverse migrated neutrophils are released into the circulation. This degree of systemic inflammation does not exceed a threshold of inflammation that is needed for the development of inflammatory complications like ARDS.

Following injury, transfusion of red blood cells (RBCs) of increased storage duration has been associated with an increased morbidity and mortality. Prospective trials focusing on the impact of the storage age of RBCs in severely bleeding trauma patients have failed to accrue patients. This has been attributed to an inability to maintain a large inventory of fresh RBCs, and the difficulties in obtaining consent in severely bleeding trauma patients. To address these issues, we performed a prospective, observational pilot study to evaluate the feasibility of conducting a trial focusing on RBC age in patients following injury. ⋯ It appears feasible to conduct a RBC age trial in trauma patients using ABO blood type to construct comparative groups. Adequate RBC age separation between cohorts and reduced RBC age in the "young" group of patients who received units ≤10 days old was achieved.

The study was conducted to achieve early detection of increased compartment pressure by comparing the changes between the thickness and pressure within the musculofascial compartments after lower leg injury. ⋯ In this study, the results of ICP and thickness changes of injury lower leg compared with uninjured leg revealed no statistically significant correlation. Some injuries showed a high ICP with only mild changes in thickness, while some showed a high ICP with significant changes. Although ultrasound has many advantages for the evaluation of soft tissue changes after trauma, this study revealed that thickness changes are not a predicable parameter for determining pressure on the acute fracture of lower leg.

The aim of the current study was to measure and compare the effect of calcium phosphate cement (CPC) and CPC enriched with strontium (SrCPC) for the healing of osteoporotic bone defects in the rat femur using (18)F-Sodium Fluoride dPET-CT. ⋯ We found PET scanning using (18)F-Sodium Fluoride to be a sensitive and useful method for evaluation of bone healing after replacement with CPC or SrCPC.
