PURPOSE: The objective of this paper is to provide a new method for estimating crash rate and severity simultaneously. METHODS: This study explores a Heckman selection model of the crash rate and severity simultaneously at different levels and a two-step procedure is used to investigate the crash rate and severity levels. The first step uses a probit regression model to determine the sample selection process, and the second step develops a multiple regression model to simultaneously evaluate the crash rate and severity for slight injury/kill or serious injury (KSI), respectively...

This review looks critically at the relevance of lead (Pb2+) toxicity and proposed mechanisms of Pb2+ -induced stress in algae and higher plants. As a basis, the current main sources of Pb2+ contamination in the environment are presented, which include agriculture, industry, and road traffic. Further, bioavailability of lead is discussed as a basis for evaluating the environmental relevance of the many studies on lead toxicity that have been published in the past decades. These studies suggest three main mechanisms of toxicity of Pb2+: inhibition of photosynthesis, oxidative stress, and "genotoxicity" including DNA damage and defects in mitosis...

INTRODUCTION: Traffic-related air pollution causes fatty liver, inflammation and fibrosis in animal models, but there have been few studies in humans. OBJECTIVES: To test the hypothesis that traffic-related air pollution causes non-alcoholic fatty liver disease (NAFLD) and increased markers for non-alcoholic steatohepatitis (NASH); and that NAFLD increases liver susceptibility to increased NASH risk. METHODS: Data collected prospectively from 74 overweight or obese children were obtained from the Yale Pediatric Obesity Clinic...

Rollover crashes are responsible for a notable number of serious injuries and fatalities; hence, they are of great concern to transportation officials and safety researchers. However, only few published studies have analyzed the factors associated with severity outcomes of rollover crashes. This research has two objectives. The first objective is to investigate the effects of various factors, of which some have been rarely reported in the existing studies, on the injury severities of single-vehicle (SV) rollover crashes based on six-year crash data collected on the Malaysian federal roads...

INTRODUCTION: Road traffic crashes (RTC) are an important public health problem, accounting for 1.2 million deaths per year worldwide. In Brazil, approximately 40,000 deaths caused by RTC occur every year, with different trends in the Federal Units. However, these figures may be even greater if health databases are linked to police records. In addition, the linkage procedure would make it possible to qualify information from the health and police databases, improving the quality of the data regarding underlying cause of death, cause of injury in hospital records, and injury severity...

This mixed method study investigated the short and long term effects of peer loss on eight adolescents after a fatal school bus accident. Phenomenological analysis of their retrospective narratives revealed three patterns (living in despair, collecting my pieces, remembering and moving on). Quantitative findings indicate progressive decrease in post traumatic stress symptoms severity across time; increase in positive changes in perceptions of self, others, and life between 18 and 34 months; and stable continuing bond with the deceased peers...

INTRODUCTION: Traumatic spinal cord injury (SCI) is one of the major causes for poor outcomes of pregnancy. Injury during pregnancy is uncommon; therefore, outcome data are scarce. This case series presents outcomes of pregnancy in five women who sustained SCI during their pregnancies. CASE PRESENTATION: Five women who sustained SCIs during pregnancy (age range: 24-38 years) were identified and included in this case series. The causes of SCI in this population were fall from heights (cases 1 and 2), road traffic accidents (cases 3 and 4) and firearm injury (case 5)...

Self-driving cars are posing a new challenge to our ethics. By using algorithms to make decisions in situations where harming humans is possible, probable, or even unavoidable, a self-driving car's ethical behavior comes pre-defined. Ad hoc decisions are made in milliseconds, but can be based on extensive research and debates. The same algorithms are also likely to be used in millions of cars at a time, increasing the impact of any inherent biases, and increasing the importance of getting it right. Previous research has shown that moral judgment and behavior are highly context-dependent, and comprehensive and nuanced models of the underlying cognitive processes are out of reach to date...

Amphibian populations have been declining globally over the past decades. The intensification of agriculture, habitat loss, fragmentation of populations and toxic substances in the environment are considered as driving factors for this decline. Today, about 50% of the area of Germany is used for agriculture and is inhabited by a diverse variety of 20 amphibian species. Of these, 19 are exhibiting declining populations. Due to the protection status of native amphibian species, it is important to evaluate the effect of land use and associated stressors (such as road mortality and pesticide toxicity) on the genetic population structure of amphibians in agricultural landscapes...

The toxic metal lead (Pb) can be harmful to human health in various manners, but is also considered as a distinguished tracer of environmental pollution since the relative abundance of its four stable isotopes with the atomic masses of 204, 206, 207, and 208 varies with the emission source. This study is focused on the Pb concentrations and isotope ratios in the particulate matter of the Brazilian city of Goiânia in order to determine the main Pb emission sources. Particulate matter samples were collected on clean Teflon filters during rainy and dry season in 2014 in the center of Goiânia city near main roads with a high traffic volume...

The occurrence and rate of wildlife-vehicle collisions are related to both anthropocentric and environmental variables, however, few studies compare collision risks for multiple species within a model framework that is adaptable and transferable. Our research compares collision risk for multiple species across a large geographic area using a conceptually simple risk framework. We used six species of native terrestrial mammal often involved with wildlife-vehicle collisions in south-east Australia. We related collisions reported to a wildlife organisation to the co-occurrence of each species and a threatening process (presence and movement of road vehicles)...

Survival following trachea-esophageal transection is uncommon. Establishing a secure airway has the highest priority in trauma management. Airway management is a unique and a defining element to the specialty of emergency medicine. There is no doubt regarding the significance of establishing a patent airway in the critically ill patient in the emergency department. Cannot intubate and cannot ventilate situation is a nightmare to all emergency physicians. The most important take-home message from this case report is that every Emergency physician should have the ability to predict "difficult airway" and recognize "failed airway" very early and be skilled in performing rescue techniques when routine oral-tracheal intubation fails...
