Beef cattle breeding has always been highlighted in the political, economic and social histories of Argentina and Brazil. The refrigeration industry, due to its intermediate position between production and consumption, suffered directly or indirectly the impacts of political actions, from protagonist to supporting at different times, both in Argentina and Brazil. Focusing on the last 50 years, this study points out the main movements of the refrigeration industry in both countries, facing the national and international conjunctures of the beef market. In this comparative historical-economic analysis, it is possible to see that the State is an important inducer of the issue in question, when it establishes price control policies and institutional arrangements that affect the sector's credit and governance.

This article addresses a problem of increasing relevance in the social sciences: that one related to the anatomy and the effects of urban renewal processes. It does not stop in any of the many metropolitan areas of the region, but in an intermediate city: Neuquén, in Argentine Patagonia. The chosen time arc corresponds to the 2010-2018 period, when the height growth gained an unusual impetus. The itinerary followed by the text identifies four moments. In the first, focus is on the social division of space in the capital of Neuquén. In the second, the factors that led to the process of verticalization (urbanization of capital, extractive economy, regulatory flexibility and cultural transformations) will be reviewed. In the third, the text will stop in the process of (re) densification, emphasizing the quantity, location and size of the towers that sprayed the geography of the city.  Finally, we will analyze the social effects that growth in height brought with it, based on the assumption that it was an exclusive renovation process, which reinforced the city's segregation map.

Introduction: in Mexico, tobacco and alcohol consumption represent a public health problem. Screening, brief intervention, and treatment models had shown effectiveness to reduce substances use, which is why they have been widely used in a variety of settings. The proximity of trained human resources with consumption problems and diverse situations is one of the most important opportunities they offer. Despite the extensive experience in developing these models, they have been poorly adapted for use by medical and health personnel at the first level of care.  Objective: describe barriers and opportunities encountered during the operational implementation of a pilot project for screening, brief counseling and treatment aimed at medical personnel and related to the first level of health care in a Sanitary Jurisdiction of the State of Mexico.  Method: two focus groups were carried out on a randomized sample of 15 of 64 certified health professionals who developed practical experience performing interventions with the population of their Health Establishment.  Results: communication, personal and organizational barriers were found, however, opportunities that emerged from the implementation of this intervention model were also identified.  Discussion and conclusions: the implementation of these interventions in the first level of care has various advantages for the personnel who apply them and the population that receives it, among which the increase in productivity of the screening and brief counseling actions reported in the System of Health Information as well as the opportunity to provide the user a personalized intervention specifically focused on their local population-based problems.

Introduction: the emergence of the pandemic caused by the SARS-Cov-2 virus has generated lifestyles changes for humanity. Strategies to prevent exponential contagion and the collapse of health systems such as social-distancing and quarantine have affected people in different ways according to their vulnerability, including marijuana consumers. Objective: to learn if the regular consumers of marijuana who remained in physical and social isolation due to COVID-19 altered or modified their consumption, in their disposition and in their method of supply. Method: a cross-sectional, non-probabilistic and analytical study that used the snowball technique, aimed at regular marijuana consumers in Mexico, of legal age, who have access to the Internet and/or WhatsApp. Results: 50 men and 25 women participated, most from the state of Veracruz; the only mood related variable that was statistically significant was the relief provided by marijuana use and level of marijuana use during quarantine, as well there were changes in consumption, in the method of supply and in the relationship established with the people with whom they live. Conclusions: this work addresses an emerging problem of which little is still known, especially regarding its correlation with mental health and disorders resulting from the use of psychoactive substances. Thus, contributing a building basis for understanding the impact of quarantine and for the attention of marijuana consumers.

Introduction: the conditions of the COVID-19 pandemic promote mental health risks. Objective: the goal of the study was to assess the risk of developing mental health conditions as a result of COVID-19 situations: containment, symptoms or COVID-19 suspected, death of near people, use of alcohol, and violence. Method: it participated 8,348 Mexican, with a mean of 25 years old (SD =11.24), 50% single (4,133), 69% women (5,720), 47% in quarantine (3,948), 50% partially in quarantine (4,193), and 3% that they were not in quarantine (207). The kind proposed was a predictive correlational study using the WebApp application of the Questionnaire of Mental Health Screening in COVID-19 (Alpha= 0.96; 64 of explained variance) programed by Linux®, PHP ®, HTML®, CSS ®, and JavaScript®). Latent variables derivate of 124 iterations with 103 parameters (t[496] = 201,464, p=.000), a CFI = 0.921, a TLI = 0.908, a RMSEA = 0.067 (0.066 – 0.068), and a SRMR = 0.051. Results: results showed that avoidance predicted acute stress, this predicted anxiety related to health; anxiety related to health predicted generalized anxiety/sadness and somatization; and generalized anxiety/sadness predicted, disengagement/anger in people. Discussion and conclusions: containment, symptoms, or suspected COVID-19, explosive use of alcohol or reporting of emotional or physical violence, were associated with the risk of mental health conditions. Next studies should assess the impact of distance psychological interventions over the risk of developing acute and posttraumatic stress.

Introduction: opioids are the substance responsible for the highest number of deaths from drug use worldwide. According to the Survey on Drug, Alcohol and Tobacco Use in Mexico, 0.2% of the population (just over 145,000 people) have used heroin once in their lives.  Objective: to analyze the trends in heroin use, including the estimation of the average annual growth rate, in patients treated at CIJ between 2013 and 2019 and to explore and compare their sociodemographic profile and pattern of use with that of users of other illicit drugs.  Method: a study based on the analysis of trends and the estimation of the average annual growth rate from databases of a census registry of patients, as well as on comparative analysis, based on bivariate tests of two groups of drug users.  Results: the proportion of heroin-consuming patients showed a gradual increase until the middle of the period 2013-2019, reaching its highest prevalence in 2016, to start falling from there, especially among men. The sociodemographic profile of heroin users shows a greater physical and psychosocial impact compared to those of other substances.  Conclusions: there is a decrease in the demand for treatment, at least in CIJ, consistent with the prevalence observed in the general population, highlighting that this decrease does not occur among women, especially among younger women, even an increase in consumption is observed.

Introduction: many studies have concluded that self-efficacy is an essential variable within the area of drug addictions and a key to maintaining abstinence and preventing relapses. The Situational Confidence Questionnaire by Annis et al. (1987), is one of the most used instruments to measure self-efficacy and has had various modifications. The Brief Situational Confidence Questionnaire (CBCS), is the shortest version with only 8 items. Objective: to obtain the factor validity and reliability of the CBCS with a clinical sample in residential modality. Method: the study was carried out with a sample of 41 volunteers patients, adolescents, and adults interned in a residential rehabilitation center. The evaluation met the standards for the development and review of instrumental studies. Results: after carrying out the exploratory factor analysis, the eight original items were left within a single factor which explains 71.39% of the variance, with a factor load between the ranges of .76 and .91, and with an internal consistency of .941. Discussion and conclusions: the Brief Situational Confidence Questionnaire presents an internal consistency with high reliability and acceptable factor loads, such as was found in other studies. Therefore, its use in Mexico is suggested as an evaluation tool in a clinical setting, with patients who are interned in a rehabilitation center. It is recommended to carry out replications with more representative and randomly selected samples. Furthermore, it is suggested to include confirmatory factor analysis to obtain greater certainty in the results.

Introduction: exponential and excessive use of social networks like Facebook could lead to greater exposure of alcohol-related content and influence adolescent drinking behavior.  Objective: to determine the influence of the exposure of alcohol-related content on the pattern of alcohol consumption, in addition to knowing the differences in frequency and exposure of alcohol-related content on Facebook in consumers and non-consumers of alcohol.  Method: a predictive correlational study was carried out, with 672 adolescents from technical high schools, a data card, the Facebook use questionnaire (CUF) and the Alcohol Use Disorders Identification Test (AUDIT) were used.  Results: significant differences in exposure to alcohol-related content on Facebook were found, with higher means and medians among adolescents who reported alcohol consumption compared to those who did not (U = 40875.0, p =.001). In addition, regression analysis revealed that hours per day on Facebook and exposure to alcohol-related content on Facebook predict alcohol consumption in adolescents.  Discussion and conclusions: alcohol consumers presented greater exposure to alcohol-related content, in addition it was found that the current alcohol consumption behavior was explained through the number of hours per day of Facebook use and exposure.

En los últimos años ha habido un aumento sin precedentes en el número, tipo y disponibilidad de nuevas sustancias psicoactivas (NPS, por sus siglas en inglés) en diversas regiones del mundo. El crecimiento en este mercado también es responsable del aumento de daños graves reportados recientemente. Los desafíos clave giran en torno a la velocidad a la que aparecen las NPS, su proliferación rápida y abierta, y la información limitada o nula sobre sus efectos y daños.
