Traumatic brain injury (TBI) is the leading cause of disability, mor­bidity and mortality in young people. As these individuals are vulner­able to the consumption of alcoholic beverages, this is a major public health issue with a high impact on socioeconomic costs. This study analyzed 138 patients treated at Hospital de Base for TBIs due to traffic accidents inside the urban area of Sao Jose do Rio Preto in the period from 2005 to 2008. Of these patients, 115 were male (83.3%) with a mean age of 38.9 years and 23 were female with a mean age of 42.4 years. There was a statistically non-significant decrease in the frequency of TBIs in the first half of 2008, that is, when stricter drink-driving laws were introduced. We conclude that urban TBIs predominantly affect young men and that there was no statistical cor­relation between the introduction of stricter drink-driving laws and a reduction in TBIs.

Violence by and towards young people has become a major public health issue. Increased lethality, more random violence and fewer safe places largely account for the high levels of fear experienced by both children and adults. In the field of child protection and domestic violence, where traditionally the child is referred as the victim not the perpetrator, child psychiatrists are well versed, practised and skilled in the assessment of children and families. However, young people are increasingly being referred to child and adolescent mental health teams for assessment because of violent acts that they have carried out. This is reflected in heavy case-loads of children with conduct disorder who have multi-morbidity and complex need. In England and Wales, health (including mental health), social care and education services are mandated to assist youth offending teams.

Road traffic accidents are a leading cause of premature deaths and globally pose a severe threat to human lives. In particular, pedestrians crossing the road present a major cause of vehicle–pedestrian accidents in South Korea, but we lack dense behavioral data to understand the risk they face. This paper proposes a new analytical system for potential pedestrian risk scenes based on video footage obtained by road security cameras already deployed at unsignalized crosswalks. The system can automatically extract the behavioral features of vehicles and pedestrians, affecting the likelihood of potentially dangerous situations after detecting them in individual objects. With these features, we can analyze the movement patterns of vehicles and pedestrians at individual sites, and understand where potential traffic risk scenes occur frequently. Experiments were conducted on four selected behavioral features: vehicle velocity, pedestrian position, vehicle–pedestrian distance, and vehicle–crosswalk distance. Then, to show how they can be useful for monitoring the traffic behaviors on the road, the features are visualized and interpreted to show how they may or may not contribute to potential pedestrian risks at these crosswalks: (i) by analyzing vehicle velocity changes near the crosswalk when there are no pedestrians present; and (ii) analyzing vehicle velocities by vehicle–pedestrian distances when pedestrians are on the crosswalk. The feasibility of the proposed system is validated by applying the system to multiple unsignalized crosswalks in Osan city, South Korea.

Chronic hepatitis C remains one of the main causes of chronic liver disease worldwide and presents a variable natural history ranging from minimal changes to advanced fibrosis and cirrhosis and its complications, such as development of hepatocellular carcinoma. Approximately, 1.45 million people are estimated to be infected by HCV in Brazil representing a major public health issue. The aim of this paper was to review the epidemiology and management of chronic hepatitis C from a Brazilian perspective. The management of chronic hepatitis C has been challenged by the use of noninvasive methods to stage liver fibrosis as an alternative to liver biopsy and the high cost of new interferon-free antiviral treatments. Moreover, the need of cost-effectiveness analysis in hepatitis C and the recent changes in treatment protocols were discussed.

The road traffic accidents caused huge economic losses and casualties, so it had been focused by the researchers. Lane changing characteristic is the most relevant characteristic with safety. The intent of lane changing was discussed. Firstly, the factors affecting the intent were analyzed, the speed satisfaction value and the space satisfaction value were proposed; then the data from the University of California, Berkeley was extracted and the number of vehicles changed lane more often and the vehicle ID were obtained; the BP neural network classification model was established, it was trained and testified by actual data. The results shown the method could predict the intent accurately.

Aim: Hepatitis E virus (HEV) transmission through blood transfusion is a major public health issue worldwide. We aimed to determine the seroprevalence of HEV in blood donors in the Qassim region of Saudi Arabia. Materials & methods: Serum samples (n = 1078) were collected from volunteer blood donors and tested for the presence of anti-HEV IgG and IgM by indirect ELISA. Results: The seroprevalence of anti-HEV IgG among the blood donors was 5.7% overall. Anti-HEV IgG and IgM seropositivity were significantly higher in non-Saudi donors than in Saudi donors (22.1 vs 3 and 7.8 vs 0.2% for anti-HEV IgG and IgM, respectively). Conclusion: The seroprevalence of HEV among blood donors in the Qassim region was lower than previous estimates for other regions of the country and neighboring countries.

The number of vehicles on the roads of Almaty, Kazakhstan is growing from year to year. This brings about an increasing intensity and density of traffic flows in the streets which leads to congestion, decreasing speed of the traffic flow, increasing environmental pollution caused by car emissions, and which can potentially lead to the road traffic accidents (RTA), including fatalities. While the number of injuries grows up mainly due to drivers’ non-compliance with the speed limit, the environmental pollution is caused by longer traffic jams. Therefore, to reduce the level of road traffic injuries and emissions into the environment it is necessary to ensure the uniform movement of traffic flows in cities. Currently, one of the effective ways to do it is the use of transport telematics systems, in particular, control systems for road signs, road boards and traffic lights. The paper presents an analysis of existing systems and methods of traffic light regulation. The  analyses of the systems and methods are based on the use of homogeneous data, that is the data on standard parameters of traffic flows. The need in collecting and analyzing additional semi-structured data on the factors that have a significant impact on the traffic flows parameters in cities is shown as well. The work is dedicated to solving the problem of analysis and forecast of traffic flows in the city of Almaty, Kazakhstan. GPS data on the location of individual vehicles is used as the initial data for solving this problem. By projecting the obtained information onto the graph of the city's transport network, as well as using additional filtering, it is possible to obtain an estimate of individual parameters of traffic flows. These parameters are used for short-term forecast of the changes in the city's transport network.
