A morphological study of adult liver flukes and eggs from sheep in a human fascioliasis endemic zone in the Northern Bolivian Altiplano showed that they belong to the species Fasciola hepatica. An exhaustive morphometric comparison with a F. hepatica population from Spanish sheep was made using image analysis and an allometric model: (y2m - y2)]#x002F;y2 = c[(y1m - y1)/y1]b, where y1 = body surface or body length, y2 = one of the measurements analysed, y1m, y2m = maximum values towards which y1 and y2 respectively tend, and c, b = constants. Only slight allometric differences in worms were observed despite the geographic distance between both Spanish and Bolivian sheep populations and the very high altitude of the Bolivian Altiplano.

Gambling is legal in most countries. However, despite having some economic benefits, certain characteristics of gambling can have health consequences, rendering it a public health issue. The effects can be summarized according to the following three “laws” of ethical gambling: “Gambling Dynamics Law”: companies’ economic gains come directly from players’ losses; “Expected Loss Law”: the more one gambles, the greater the probability of losing; and “Addiction Law”: the more one gambles, the greater the need to play again, leading to further losses. Ludens is a gambling addiction prevention program that has four goals: inform participants about gambling and gambling addiction; sensitize participants to the risk of gambling for health, especially addiction; promote a change in attitudes toward gambling; and alert participants to risky behaviors that can lead to addiction. The prevention program was implemented during 2017 to 2019. Fourteen psychologists presented it to 2372 adolescents (48.8% females, 51.2% males) aged 14–19 years, none of whom were university students, recruited from 42 Spanish high schools in 132 groups taking different courses. The main dependent variables analyzed were the monthly frequencies of gambling, at-risk gambling, and gambling addiction (as measured by the National Opinion Research Center DSM-IV Screen for Gambling Problems, adapted to diagnose gambling disorder according to DSM-5, in which pathological gambling is considered an addictive disorder). Given that all of the gamblers were adolescents (most were minors), fulfilment of 1–3 the DSM-5 diagnostic criteria was considered to indicate a risk of problem gambling. After the administration of Ludens, statistically significant reductions were observed in the three variables of interest: monthly frequency of gambling, percentage of adolescents with risky gambling, and percentage of adolescents with gambling disorder. The results were analyzed according to sex and age (minors vs. adolescents between 18 and 19 years old). The results obtained after applying the prevention program indicate that Ludens is effective as a universal prevention program for gambling addiction.

Recently, some governments and other stakeholders in countries where online gambling has been legalized have implemented responsible gambling policies. From the theoretical and empirical evidence in this study, we show that these responsible gambling policies are insufficient to prevent the emergence of pathological gambling disorder in society, especially among adolescents. Since online gambling was legalized in Spain in June 2012, online gambling companies have been required by law to implement responsible gambling policies. The implemented policies largely consist of informing customers of the dangers of gambling and how to minimize harm by engaging in behaviour that prevents addiction. However, online gambling addiction has increased exponentially; at present, it is the second most common form of pathological gambling in Spain and the most common form among young children and adolescents (Chóliz, 2016). In our study involving 6,053 underage adolescents, the results showed that more than half of them had gambled and that the prevalence rate of pathological gambling was triple that of the general population. Our main conclusions are that online gambling especially affects male minors, some of whom have developed gambling disorders since the legalization (and broad promotion) of online gambling in Spain. Responsible gambling policies implemented by the conservative government of Spain (2011–2018) and by gambling companies were insufficient to prevent such disorders from becoming an epidemic among Spanish adolescents.

Desde la legalización del juego online en España el trastorno de juego se ha incrementado notablemente, ya que ha aumentado la disponibilidad y accesibilidad de un tipo de juego que es, de por sí, más adictivo que el tradicional. Aunque las tasas de prevalencia son superiores en hombres que en mujeres, ellas no son ajenas a este problema, que también suele concurrir con otros problemas de índole emocional. El trabajo que presentamos es un estudio de caso de una mujer procedente de los servicios de salud mental, que padecía, además de adicción al juego, una importante sintomatología clínica. Se describe el protocolo de tratamiento de adicción al juego online desarrollado en la Unidad de Investigación: “Juego y adicciones tecnológicas” de la Universidad de Valencia, que recoge las aportaciones de diversas investigaciones científicas. El tratamiento conductual cognitivo que le fue aplicado no solamente tuvo eficacia en la reducción del juego, sino que produjo un radical cambio en estilo de vida, actitudes hacia el juego y sintomatología clínica
