The aim of this study is to describe the trends of transport accident mortality in Chile from 2000 to 2012 by year, geographic distribution, gender, age group, and type of accident. Population-based study. Data for transport accident mortality in Chile between 2000 and 2012 were used. The crude and adjusted per region transport accident mortality rates were calculated per 100,000 inhabitants. The annual percentage change (APC) of the rates and relative risks (RR) were calculated. The average transport accident mortality rate (TAMR) in Chile (2000-2012) was 12...

Wildfires constitute the greatest economic disruption to Mediterranean ecosystems, from a socio-economic and ecological perspective (Molina et al., 2014). This study proposes to classify fire intensity levels based on potential fire behavior in different types of Mediterranean vegetation types, using two geographical scales. The study considered >4 thousand wildfires over a period of 25years, identifying fire behavior on each event, based on simulations using "KITRAL", a model developed in Chile in 1993 and currently used in the entire country...

Liolaemus is a diverse genus of lizards, subdivided into two subgenera: Liolaemus (sensu stricto) and Eulaemus, distributed mainly in Chile and Argentina. The Liolaemus elongatus-kriegi complex is the most diverse group within Liolaemus (sensu stricto), especially the species closely related to Liolaemus elongatus, which form a clade currently comprising nine species. Several Chilean species of this group have been recently described, mainly from volcanoes and poorly explored mountains. Here molecular and morphological evidence are provided for a new species of the Liolaemus elongatus clade, which is characterized by its small size and lack of dorsal pattern, unusual features for the species of this group of lizards...

BACKGROUND: A growing number of studies have identified an association between exposure to inorganic arsenic and hypertension. However, results have not been consistent across studies. Additional studies are warranted, given the global prevalence of both arsenic exposure and morbidity attributable to hypertension. METHODS: We analyzed data collected from October 2007-December 2010 for a population-based cancer case-control study in northern Chile. Data included lifetime individual arsenic exposure estimates and information on potential confounders for a total of 1266 subjects...

REVIEW
Øystein Evensen
Salmonid rickettsial septicemia (SRS) is a serious, infectious disease in Chilean salmon farming caused by Piscirickettsia salmonis, causing heavy losses to the salmonid industry. P. salmonis belongs to the Gammaproteobacteria, order Thiotrichales. SRS was first described in Chile in 1989, and infection with P. salmonis has since been described from a high number of fish species and in several geographic regions globally. P. salmonis infection of salmonids causes multifocal, necrotic areas of internal organs such as liver, kidney, and spleen...

OBJECTIVES: We analyze the impact of adolescent motherhood on several education and labor market outcomes in Chile over the 1990-2013 period. We explore whether effects are different across income levels, timing of adolescent births, and three sub-periods. METHODS: Using the CASEN national household survey, we applied propensity score-matching methods on two samples of women aged 24: one for women in the 2009-2013 period and another sample of 24-year-old women living with their mother between 1990-2013...

Bacteriophages infecting the fish pathogen Flavobacterium psychrophilum can potentially be used to prevent and control outbreaks of this bacterium in salmonid aquaculture. However, application of bacteriophages in disease control requires detailed knowledge on their genetic composition. To explore the diversity of F. pyschrophilum bacteriophages we have analyzed the complete genome sequences of 17 phages isolated from two distant geographic areas (Denmark and Chile), including the previously characterized temperate bacteriophage 6H...

The effects of noise pollution on human quality of life and health were recognised by the World Health Organisation a long time ago. There is a crucial dilemma for the study of urban noise when one is looking for proven methodologies that can allow, on the one hand, an increase in the quality of predictions, and on the other hand, saving resources in the spatial and temporal sampling. The temporal structure of urban noise is studied in this work from a different point of view. This methodology, based on Fourier analysis, is applied to several measurements of urban noise, mainly from road traffic and one-week long, carried out in two cities located on different continents and with different sociological life styles (Cáceres, Spain and Talca, Chile)...

Ricardo Espinoza González
Gastrointestinal bezoars are a concretion of indigested material that can be found in the gastrointestinal tract of humans and some animals. This material forms an intraluminal mass, more commonly located in the stomach. During a large period of history animal bezoars were considered antidotes to poisons and diseases. We report a historical overview since bezoars stones were thought to have medicinal properties. This magic conception was introduced in South America by Spanish conquerors. In Chile, bezoars are commonly found in a camelid named guanaco (Lama guanicoe)...

The Mediterranean diet is currently considered a functional diet with an increasing amount of scientific evidence that supports its beneficial effects in human health. Several observational cross-sectional and prospective cohort studies show an association between this diet and a lower prevalence and incidence of chronic diseases, such as cardiovascular disease, cancer, metabolic syndrome, diabetes, and neurodegenerative diseases as well as a reduced overall mortality. Additionally, clinical interventional studies, particularly the PREDIMED (Prevención con Dieta Mediterránea) initiative, have shown, with high quality scientific evidence, that a Mediterranean diet -supplemented either with olive oil or nuts- can lower by 30% the incidence of cardiovascular disease, reverse the metabolic syndrome, and prevent the development of diabetes and aging-related cognitive decline...

BACKGROUND: The effect of food fortification with folic acid on the incidence of lip-palate fissures (FLP) is under discussion. AIM: To calculate the rate of hospital discharges due to cleft lip and palate (CLP) and explore whether they decreased after the start of folic acid fortification in Chile. MATERIAL AND METHODS: The hospital discharge databases published by the Chilean Ministry of Health were analyzed. The trends of discharge rates due to CLP of children of less than one year of life (ICD-10 Q350-379 code) and live births (lb) were calculated from 1986 to 2012...

We surveyed users of the Hospital Comunitario de Salud Familiar El Carmen and their companions to analyze knowledge and practices regarding cystic echinococcosis and trichinellosis. Most people recognized risky practices. Previous attendance at talks and working in agricultural-livestock enhanced the knowledge. Age, sex and formal education were not associated with the knowledge. Knowledge was not associated with practices.

Dengue was first diagnosed on Easter Island on year 2002 and thereafter recurrent outbreaks have occurred involving different serotypes of dengue virus. Its vector, Aedes aegypti has not been eliminated despite the small size of the island. Conditions at the local hospital preclude adequate management of severe and hemorrhagic cases due to the absence of a Critical Care Unit as well as no availability of platelets, or plasma units for transfusion. Besides, transfer, of severely affected patients to continental Chile is cumbersome, slow and expensive...
