Analysis of Some Farm Driving Variables and Its Relation with Milk Production in a Pastoral Dairy Farm of Buenos Aires, Argentina

The quantity of milk solids produced determines a dairy farm income and contributes to its profit. Total pasture production, forage quality and herd consumption are factors to be managed in this production system. The outcomes of two years were analyzed. Primary production showed its dependence on climatic conditions and use of technological inputs. Forage quality was promoted through interseeding legumes, applying fertilizer and maintaining the pasture young and leafy. Total forage removed by the herd was similar in both years although pasture production decreased. It was possible to cope with seasonal variations in forage production, by varying the grazing pressure and this allowed an increase in daily herd milk production and annual fat production per hectare. Changes in milk production per cow was not related to changes in stocking rate, however, although the nutritive value of the pasture was improved during the second period, daily milk production and forage consumption per animal decreased when grazing pressure increased. The relation between total milk produced and total dry matter consumed in both periods were similar

Global mental health and climate change: A geo-psychiatry perspectiv

Climate changes affect planet ecosystems, living beings, humans, including their lives, rights, economy, housing, migration, and both physical and mental health. Geo-psychiatry is a new discipline within the field of psychiatry studying the interface between various geo-political factors including geographical, political, economic, commercial and cultural determinants which affect society and psychiatry: it provides a holistic overview on global issues such as climate changes, poverty, public health and accessibility to health care. It identifies geopolitical factors and their effects at the international and national levels, as well as considers the politics of climate changes and poverty within this context. This paper then introduces the Compassion, Assertive Action, Pragmatism, and Evidence Vulnerability Index (CAPE-VI) as a global foreign policy index: CAPE-VI calculates how foreign aid should be prioritised for countries that are at risk or already considered to be fragile. These countries are characterised by various forms of conflict, disadvantaged by extremes of climate change, poverty, human rights abuses, and suffering from internal warfare or terrorism

Prevalence and Associated Factors of Depression, Anxiety, and Stress in University Students in Paraguay during the COVID-19 Pandemic

We aimed to determine the prevalence of depression, anxiety, and stress in university students in Paraguay during the COVID-19 pandemic. A cross-sectional study was conducted among 293 students from four universities in Paraguay in 2021. The DASS-21 mental health scale was used to measure the outcomes (depression, anxiety, and stress) and evaluate their association with socio-educational variables. A total of 77.1% of the participants were women and 136 (46.4%) were between 21 and 25 years old. The prevalence of depression, anxiety, and stress was 74.7%, 87.4%, and 57%, respectively. We found that being a woman and studying at a public university was positively associated with depression, anxiety, and stress. Receiving COVID-19 training increases the prevalence of mental health problems. In conclusion, high levels of anxiety, depression, and stress were found in university students during the COVID-19 pandemic. Being a woman, studying at a public university, and receiving training on COVID-19 were factors associated with a higher prevalence of presenting all the mental health problems evaluated. Furthermore, students aged 31 and over had a higher prevalence of depression and stress

Determinación de salud auto-percibida en una población rural del Paraguay implementando el cuestionario de Goldberg -GHQ12- en guaraní

Introducción: El cuestionario de Salud Auto-percibida de Goldberg constituye una evaluación de la percepción personal de salud de los individuos. No se tiene evidencia de la aplicación del cuestionario en poblaciones rurales del Paraguay, por lo que el objetivo del estudio fue su implementación en dicho sector demográfico para conocer los niveles de salud auto-percibida. Asimismo, se procedió a la traducción del cuestionario de Goldberg -GHQ12- al idioma guaraní, para hacer este instrumento más acorde a las poblaciones rurales del Paraguay. Materiales y Métodos: El cuestionario está formado por 12 preguntas que expresan actitudes específicas o síntomas. Un resultado positivo indica riesgo de patología mental. Se aplicó en el asentamiento San Antonio, Departamento de San Pedro, durante mayo y junio de 2013. Resultados: Un total de 74 personas fueron encuestadas, con un promedio de edad de 39±15,4 años. El puntaje promedio fue de 4,13±1,98. El 27% de los individuos presentaron riesgo de patología emocional. No se encontraron diferencias significativas entre sexos ni correlación entre edad y puntaje obtenido. Conclusión: El porcentaje de personas en riesgo concuerda con los valores encontrados en la población general. Se constató que el sexo y la edad no influyeron en gran medida en los puntajes, corroborando hallazgos de algunos estudios previos, a pesar de la gran discordancia hallada en la bibliografía. A pesar del porcentaje coherente con el resto de la población, el limitado acceso a profesionales de la salud dificulta el diagnóstico y tratamiento de patologías mentales en este sector demográfico

Trastorno por déficit de atención e hiperactividad dual en niños y adolescentes internados en un centro para el tratamiento de adicciones

Introducción: El trastorno por déficit de atención e hiperactividad es el trastorno psiquiátrico más frecuente en la edad escolar y múltiples estudios han evidenciado que es un factor de riesgo independiente para desarrollar abuso o dependencia de sustancias. El objetivo principal de este trabajo es determinar la frecuencia de este trastorno y otros trastornos externalizantes en niños y adolescentes internados en un centro de referencia, así como el impacto de estas patologías en la escolarización, inicio precoz del consumo de sustancias, caracterización de las conductas adictivas y perfil de los pacientes. Sujetos y métodos: Se analizaron las historias clínicas de la totalidad de niños y adolescentes internados en un centro de referencia durante los meses de junio y julio de 2013, todos ellos con el diagnóstico de trastorno por uso de sustancias. Se realizaron entrevistas estructuradas para los diagnósticos de déficit de atención e hiperactividad y otros trastornos externalizantes. Resultados: Se determinó la presencia de comorbilidad con déficit de atención e hiperactividad en el 40% de los pacientes y de comorbilidad con trastorno disocial en 95% de los pacientes. Los pacientes con déficit de atención e hiperactividad presentaron mayores dificultades en la escolarización y en el inicio precoz en el uso de sustancias. Conclusión: el trastorno por déficit de atención e hiperactividad es frecuentemente minimizado en sus síntomas y sobre todo en las posibles consecuencias negativas para el paciente; si su diagnóstico no se realiza a tiempo, no será posible un buen abordaje terapéutico del niño y adolescente

Dielectron and heavy-quark production in inelastic and high-multiplicity proton-proton collisions at root s=13 TeV

The measurement of dielectron production is presented as a function of invariant mass and transverse momentum (p(T)) at midrapidity (vertical bar ye vertical bar )/dy vertical bar(y=0) = 974 +/- 138 (stat.) +/- 140 (syst.) +/- 214(BR) mu b and d sigma(b (b) over bar)/dy vertical bar(y=0) = 79 +/- 14 (stat.) +/- 11 (syst.) +/- 5(BR) mu b using PYTHIA simulations and d sigma(c (c) over bar)/dy vertical bar(y=0) = 1417 +/- 184 (stat.) +/- 204 (syst.) +/- 312(BR) mu b and d sigma(b (b) over bar)/dy vertical bar(y=0) = 48 +/- 14 (stat.) +/- 7 (syst.) +/- 3(BR) mu b for POWHEG. These values, whose uncertainties are fully correlated between the two generators, are consistent with extrapolations from lower energies. The different results obtained with POWHEG and PYTHIA imply different kinematic correlations of the heavy-quark pairs in these two generators. Furthermore, comparisons of dielectron spectra in inelastic events and in events collected with a trigger on high charged-particle multiplicities are presented in various p(T) intervals. The differences are consistent with the already measured scaling of light-hadron and open-charm production at high charged-particle multiplicity as a function of p(T). Upper limits for the contribution of virtual direct photons are extracted at 90% confidence level and found to be in agreement with pQCD calculations. (C) 2018 The Author. Published by Elsevier B.V

VAMOS: a Pathfinder for the HAWC Gamma-Ray Observatory

VAMOS was a prototype detector built in 2011 at an altitude of 4100m a.s.l. in the state of Puebla, Mexico. The aim of VAMOS was to finalize the design, construction techniques and data acquisition system of the HAWC observatory. HAWC is an air-shower array currently under construction at the same site of VAMOS with the purpose to study the TeV sky. The VAMOS setup included six water Cherenkov detectors and two different data acquisition systems. It was in operation between October 2011 and May 2012 with an average live time of 30%. Besides the scientific verification purposes, the eight months of data were used to obtain the results presented in this paper: the detector response to the Forbush decrease of March 2012, and the analysis of possible emission, at energies above 30 GeV, for long gamma-ray bursts GRB111016B and GRB120328B.Comment: Accepted for pubblication in Astroparticle Physics Journal (20 pages, 10 figures).
