BACKGROUND: Traffic accidents are the most frequent cause of genitourinary injuries (GUI). Kidney injuries following trauma have been well described. However, there exists a paucity of data on other traumatic genitourinary injuries following traffic accidents. The objective of this study was to analyze the frequency and type of all genitourinary injuries, by user category, following traffic accidents. METHODS: Patient cases were extracted from the trauma registry of the French department of Rhone from 1996 to 2013...

The aim of this study was to geospatially explore the occurrence rates of car accidents involving pedestrians in Cercado de Lima (Lima District), Peru. Car accidents involving pedestrians recorded in the 2015 National Police Station Census of the National Statistics and Information Institute were described and georeferenced. Subsequently, a Kernel Density analysis was carried out to locate areas with high, medium, and low density events. Records of 171 car accidents involving pedestrians were studied: the types of vehicles involved were automobiles (56...

Advances in virtual reality technology present new opportunities for human factors research in areas that are dangerous, difficult, or expensive to study in the real world. The authors developed a new pedestrian simulator using the HTC Vive head mounted display and Unity software. Pedestrian head position and orientation were tracked as participants attempted to safely cross a virtual signalized intersection (5.5 m). In 10% of 60 trials, a vehicle violated the traffic signal and in 10.84% of these trials, a collision between the vehicle and the pedestrian was observed...

Many coordination phenomena are based on a synchronization process, whose global behavior emerges from the interactions among the individual parts. Often in nature, such self-organized mechanism allows the system to behave as a whole and thus grounding its very first existence, or expected functioning, on such process. There are, however, cases where synchronization acts against the stability of the system; for instance in some neurodegenerative diseases or epilepsy or the famous case of Millennium Bridge where the crowd synchronization of the pedestrians seriously endangered the stability of the structure...

Background Road traffic injuries (RTIs) are a serious epidemic which claims more than a million lives across the globe each year. The burden of RTIs is particularly pronounced in Africa and other low and middle income countries. The unfavourable disparity of the burden of road trauma in the world is largely attributable to unsafe vehicles, lack of appropriate road infrastructure and the predominance of vulnerable road users (VRUs) in developing countries. However, little research exists in Northern Ghana to highlight the scale and risk of death among road users...

Particulate matter has recently received more attention than other pollutants. PM10 and PM2.5 have been primarily monitored, whereas scientists are focusing their studies on finer granulometric sizes due both to their high number concentration and their high penetration efficiency into the respiratory system. The purpose of this study is to investigate the population exposure to UltraFine Particles (UFP, submicrons in general) in outdoor environments. The particle number doses deposited into the respiratory system have been compared between healthy individuals and persons affected by Chronic Obstructive Pulmonary Disease (COPD)...

With the development of information and communications technology, user-generated content and crowdsourced data are playing a large role in studies of transport and public health. Recently, Strava, a popular website and mobile app dedicated to tracking athletic activity (cycling and running), began offering a data service called Strava Metro, designed to help transportation researchers and urban planners to improve infrastructure for cyclists and pedestrians. Strava Metro data has the potential to promote studies of cycling and health by indicating where commuting and non-commuting cycling activities are at a large spatial scale (street level and intersection level)...

The choice of the exit to egress from a facility plays a fundamental role in pedestrian modelling and simulation. Yet, empirical evidence for backing up simulation is scarce. In this contribution, we present three new groups of experiments that we conducted in different geometries. We varied parameters such as the width of the doors, the initial location and number of pedestrians which in turn affected their perception of the environment. We extracted and analysed relevant indicators such as distance to the exits and density levels...

BACKGROUND: Distracted pedestrian behavior is a significant public health concern, as research suggests distracted pedestrians have significantly higher risk of injury compared to fully attentive pedestrians. Despite this, efforts to reduce distracted pedestrian behavior are scant. OBJECTIVE: Using a repeated measures experimental research design, we implemented a behavioral intervention to reduce distracted pedestrian behavior in the high-risk environment of an urban college campus and simultaneously monitored behavior on a control urban college campus not exposed to the intervention...

We develop an interactive likelihood (ILH) for sequential Monte Carlo (SMC) methods for image-based multiple target tracking applications. The purpose of the ILH is to improve tracking accuracy by reducing the need for data association. In addition, we integrate a recently developed deep neural network for pedestrian detection along with the ILH with a multi-Bernoulli filter. We evaluate the performance of the multi-Bernoulli filter with the ILH and the pedestrian detector in a number of publicly available datasets (2003 PETS INMOVE, Australian Rules Football League (AFL) and TUD-Stadtmitte) using standard, well-known multi-target tracking metrics (optimal sub-pattern assignment (OSPA) and classification of events, activities and relationships for multi-object trackers (CLEAR MOT))...

BACKGROUND: Acute complex traumatic wounds of the lower limbs are usually managed by a combination of multiple debridements, dressing changes, and specialized surgical procedures which may include tissue transfers for the reconstruction of the soft tissue injury. The recovery is lengthy, and the outcome dependent on the initial injury, the surgical procedures undertaken and rehabilitation programs with a multidisciplinary team. METHOD: A nine-year-old male patient presented to Kimberly Hospital with an extensive soft tissue injury of the leg associated with a tibia fracture caused by a high velocity pedestrian vehicle accident...

Background: Physical activity (PA) protects against cancer and enhances cancer survivorship. Given high inactivity rates nationwide, population-level physical activity facilitators are needed. Several authoritative bodies have recognized that zoning and planning helps create activity-friendly environments. This study examined the association between activity-friendly zoning, inactivity, and cancer in 478 of the most populous U.S. counties.Methods: County geocodes linked county-level data: cancer incidence and smoking (State Cancer Profiles), inactivity (Behavioral Risk Factor Surveillance System), 11 zoning measures (compiled by the study team), and covariates (from the American Community Survey and NAVTEQ)...

Location based services can improve the quality of patient care and increase the efficiency of the healthcare systems. Among the different technologies that provide indoor positioning, inertial sensors based pedestrian dead-reckoning (PDR) is one of the more cost-effective solutions, but its performance is limited by drift problems. Regarding the heading drift, some heuristics make use of the building's dominant directions in order to reduce this problem. In this paper, we enhance the method known as improved heuristic drift elimination (iHDE) to be implemented in a Step-and-Heading (SHS) based PDR system, that allows to place the inertial sensors in almost any location of the user's body...

The aim of this work is to describe pedestrian-driver encounters, communication, and decision strategies at marked but unsignalised crossings in urban areas in the Czech Republic and the ways in which the parties involved experience and handle these encounters. A mixed-methods design was used, consisting of focus groups with pedestrians and drivers regarding their subjective views of the situations, on-site observations, camera recordings, speed measurements, the measurement of car and pedestrian densities, and brief on-site interviews with pedestrians...

We report the case of a 37-year-old female patient who required 22 surgeries following a pedestrian versus car accident. She was enrolled in a clinical study investigating emergence from anesthesia. In 10 of her 22 surgeries, we assessed her cognitive status in the postanesthesia care unit (PACU) using the Confusion Assessment Method. We observed PACU delirium in all 4 cases in which the patient received sevoflurane, but only in 1 of 6 cases in which she received propofol. The patient showed EEG α-band activity similar to that of an elderly patient who may reflect a greater risk of PACU delirium...

Person re-identification (re-id) aims to match people across non-overlapping camera views. So far the RGB-based appearance is widely used in most existing works. However, when people appeared in extreme illumination or changed clothes, the RGB appearance-based re-id methods tended to fail. To overcome this problem, we propose to exploit depth information to provide more invariant body shape and skeleton information regardless of illumination and color change. More specifically, we exploit depth voxel covariance descriptor and further propose a locally rotation invariant depth shape descriptor called Eigen-depth feature to describe pedestrian body shape...

The foot-mounted inertial navigation system is an important method of pedestrian navigation as it, in principle, does not rely any external assistance. A real-time range decomposition constraint method is proposed in this paper to combine the information of dual foot-mounted inertial navigation systems. It is well known that low-cost inertial pedestrian navigation aided with both ZUPT (zero velocity update) and the range decomposition constraint performs better than those in their own respective methods. This paper recommends that the separation distance between the position estimates of the two foot-mounted inertial navigation systems be restricted by an ellipsoidal constraint that relates to the maximum step length and the leg height...

BACKGROUND: The objective of the study was to review the utility of focused assessement with sonography for trauma (FAST) as a screening tool for blunt abdominal trauma (BAT) in children involved in high energy trauma (HET), and to determine whether a FAST could replace computed tomography (CT) in clinical decision-making regarding paediatric BAT. METHOD: Children presented at the Trauma Unit of the Red Cross War Memorial Children's Hospital, Cape Town, after HET, and underwent both a physical examination and a FAST...
