OBJECTIVES: This study aimed to build and test the models of machine learning (ML) to predict the mortality of hospitalised motorcycle riders. SETTING: The study was conducted in a level-1 trauma centre in southern Taiwan. PARTICIPANTS: Motorcycle riders who were hospitalised between January 2009 and December 2015 were classified into a training set (n=6306) and test set (n=946). Using the demographic information, injury characteristics and laboratory data of patients, logistic regression (LR), support vector machine (SVM) and decision tree (DT) analyses were performed to determine the mortality of individual motorcycle riders, under different conditions, using all samples or reduced samples, as well as all variables or selected features in the algorithm...

OBJECTIVES: Motorcycle helmet laws vary by state, with Kentucky requiring helmets only for younger riders. We hypothesized that motorcyclists injured in Kentucky and seen at a Tennessee trauma center would be more likely to be unhelmeted, have more severe head injuries, and sustain more fatal injuries than those injured in Tennessee or Virginia. METHODS: A Trauma Registry review of 729 injured motorcyclists from January 2005 through June 2015 examined state location of crash, demographics, helmet use, and clinical outcomes...

Traumatic pseudoaneurysms of the middle meningeal artery (MMA) represent less than 1% of all intracranial aneurysms, and occur mostly in association with temporal bone fractures following head trauma. Given the unknown natural history, it is unclear whether they should be treated. We present two cases of MMA pseudoaneurysms discovered during trauma workups. The first patient is a 44-year-old male with severe traumatic brain injury (TBI) following a motor vehicle accident. The patient was found to have two right-sided middle meningeal artery pseudoaneurysms that were treated successfully with Onyx® (Medtronic, Minneapolis, MN) embolization...

BACKGROUND: Controversy exists about the differences in air pollution exposure and inhalation dose between mode of transport. We aimed to review air pollution exposure and inhaled dose according to mode of transport and pollutant and their effect in terms of years of life expectancy (YLE). METHODS: In this systematic review, we searched ten online databases from inception to April 13, 2016, without language or temporal restrictions, for cohort, cross-sectional, and experimental studies that compared exposure to carbon monoxide, black carbon, nitrogen dioxide, and fine and coarse particles in active commuters (pedestrian or cyclist) and commuters using motorised transport (car, motorcycle, bus, or massive motorised transport [MMT-ie, train, subway, or metro])...

Introduction: Open femoral fractures are relatively uncommon occurrences, with few reports addressing their management. They are caused by high-energy mechanisms, and bone loss is a possible, but infrequent occurrence. We present a case in which two friends, 20- and 21-year-old males, were involved in a motorcycle collision. A large piece of bone was ejected from one patient's femur as a bony projectile and impaled the other patient's tibia, resulting in an open tibial plateau fracture...

PURPOSE: Zygomaticomaxillary complex (ZMC) fractures are frequent in facial trauma; only fractures of the mandible are more common. Although the frequency of these fractures is geographically consistent, the aetiology differs widely among countries and even regions. Differences in socio-economic status and the ageing population seem to be two causes. This retrospective epidemiological study evaluates patients who were surgically treated for ZMC fractures at a Swiss university clinic. MATERIALS AND METHODS: This study included 471 patients who were surgically treated for ZMC fractures in an oral and maxillofacial surgery clinic at a Swiss university hospital between January 2004 and December 2012...

Jonathan M Lee
This study uses repeated cross-sections of individual level crash data to study the effectiveness of motorcycle helmet legislation. Results suggest that motorcycle helmet laws reduce average individual fatality risks by 20.5%. From a policy standpoint, large states such as Florida and Texas can reduce annual motorcycle fatalities by an average 100 deaths through reinstating universal helmet laws. Valuing these fatality reductions at the U.S. DOT suggested $9.4 million value of a statistical life yields aggregate annual state benefits of approximately $940 million...

INTRODUCTION: Accurate motorcyclist mileage estimates are important because self-evaluation of riding experience is related to riding behavior, the relationship of self-reported to actual or future mileage is necessary in targeting training and considering survey responses, and motorcycle crash statistics require accurate travel data. METHOD: This study collected real-world data from motorcyclists over the course of two months to two years per rider. This paper explores motorcyclists' self-reported annual riding mileage (obtained via pre-study surveys) and the actual amount of riding during the study (based upon odometer readings and GPS data)...

It is not a common case for neurosurgery department and the other departments to perform joint operation at the same time. Patients with severe head injury are a condition in which vital signs are unstable due to severe brain swelling and increased intracranial pressure, and emergency surgery is required. A 44-year-old man visited the trauma center with a motorcycle accident. The Glasgow Coma Scale score at the time of emergency department was 3 points, and the pupil was fixed at 6 mm on both sides. His medical history was unknown...
