The current materials research field demands sophisticated tests and simulations to predict creep behavior, meet design needs, and save time and resources. This demands an appropriate mathematical formalism that can represent creep data for different materials and loading conditions. In this context, mathematical models such as θ-Projection and ν Concept can be applied to predict the behavior of materials under creep conditions. The main goal of this study involves the application of such methodologies to predict a creep curve for Ti-6Al-4V. In a preliminary assessment, both equation parameters, determined by computational techniques and an experimental database, enabled the determination of the strain-time curve of Ti-6Al-4V at 465 MPa and 500 ºC. The analysis showed that both methods have acceptable accuracy to predict primary, secondary, and tertiary creep behavior for Ti-6Al-4V. However, results indicated that the ν Concept produced a creep curve with better agreement with the experimental data. The technique used for obtaining parameters is promising and should be improved for future research.

ABSTRACT Objective: This systematic review aims to summarize the findings of studies that investigated the risk, precocity and intensity of psychosis in cannabis users, taking into account the status of legalization and/or decriminalization of cannabis use in different countries. Methodology: Articles published up to May 2018 were included, in English, Portuguese and Spanish, all extracted from the PubMed and SciELO databases, respecting the inclusion and exclusion criteria. Results: 19 studies from 18 countries were included. The relationship of cannabis use and the onset of psychotic symptoms was sufficiently substantiated. However, there was no data that supported an increase in the risk, precocity or intensity of psychosis in cannabis users from countries with higher levels of legalization/decriminalization of cannabis use to the date of the present study. Conclusion: The use of cannabis is associated with the development of psychosis. So far, there is no data pointing to an increase in the precocity, risk or intensity of psychosis in cannabis users, due to the legalization or decriminalization of the use of cannabis. However, the absence of data to date does not exclude these possibilities, since none of the studies analyzed in this review specifically assessed the effects of legalization/decriminalization policies on those outcomes. Therefore, prospective studies focused on the effects of legalization or decriminalization policies should be conducted in countries such as Canada, Spain, the United States of America (some states), the Netherlands, and Uruguay.

RESUMEN Objetivo: esta revisión sistemática pretende resumir los hallazgos de los estudios que investigaron el riesgo, la precocidad y la intensidad de la psicosis en los consumidores de cannabis, teniendo en cuenta el estado de legalización y/o despenalización del consumo de cannabis en diferentes países. Metodología: fueron incluidos artículos publicados hasta mayo de 2018, en lengua inglesa, portuguesa y española, todos extraídos de las bases de datos PubMed y SciELO, respetando los criterios de inclusión y exclusión. Resultados: se incluyeron 19 estudios de 18 países. La relación entre el consumo de cannabis y el inicio de síntomas psicóticos estuvo suficientemente fundamentada. Sin embargo, no hubo datos que respaldaran un aumento en el riesgo, la precocidad o la intensidad de la psicosis en los consumidores de cannabis de países con niveles más altos de legalización/despenalización del uso de cannabis hasta la fecha del presente estudio. Conclusión: el consumo de cannabis está asociado con el desarrollo de psicosis. Hasta el momento, no hay datos que indiquen un aumento en la precocidad, el riesgo o la intensidad de la psicosis en usuarios de cannabis, debido a la legalización o despenalización del uso de cannabis. Sin embargo, la ausencia de datos hasta la fecha no excluye estas posibilidades, ya que ninguno de los estudios analizados en esta revisión evaluó específicamente los efectos de las políticas de legalización/despenalización en esos resultados. Por ello, los estudios prospectivos centrados en los efectos de las políticas de legalización o despenalización deben llevarse a cabo en países como Canadá, España, los Estados Unidos de América (algunos estados), los Países Bajos y Uruguay.

Objectives: Prior research has indicated that no increase in suicides occurred immediately following the declaration of the COVID-19 emergency in Mexico City. Here we examine longer-term overall suicide trends and trends according to basic demographic groups. Methods: We used interrupted time-series analysis to model trends in monthly suicides before COVID-19 (January 1, 2010 to March 31, 2020), comparing the expected number of suicides both overall and according to age and sex with the observed number of suicides for the remainder of 2020 (April 1, 2020 to December 31, 2020). Results: There was an overall increase in suicides during the first 9 months of the pandemic, with a rate ratio of 2.07 (1.86-2.31). The increase began in the early months of the pandemic and remained stable and high after June 2020. Men and women, younger people (< 45) and older people (≥ 45) were affected. The increase was especially high among older women (RR = 3.33; 2.04-5.15). Conclusions: The increase in suicides in Mexico City is worrying and highlights the need to strengthen economic development, mental health, and well-being programs. Suicides among older women should be closely monitored. There is an urgent need to expand primary health care services to include robust suicide prevention and treatment options.

Abstract Objective To assess the effect of intimate partner violence on the risk of depression and depressive symptoms among adult women. Method We analyzed data from the Mexican Health Workers' Cohort study (n=470). Type and severity of intimate partner violence was ascertained between 2004 and 2011. Self-reported medical diagnosis of depression (2011) was the main outcome; depressive symptoms ascertained with the Centre for Epidemiologic Studies-Depression (CES-D) scale was the secondary outcome. Random-effects regressions were run to model the risk of depression (logistic) and depressive symptoms (linear) in relation to intimate partner violence. Results 41.9% women experienced intimate partner violence at baseline. The incidence of depression was 7.2%. The risk of depression increased with any type of IPV (adjusted odds ratio [aOR]=2.9; 95% confidence interval [95%CI]: 1.4-6.2) and with physical (aOR=4.3; 95%CI: 1.8-10.1), psychological (aOR=3.1; 95%CI: 1.4-6.6) and sexual (aOR=3.1; 95%CI: 1.2-8.2) violence. Depressive symptoms (CES-D) increased slightly with physical and sexual intimate partner violence. Conclusions Intimate partner violence was associated with a higher risk of depression in this sample of women working in a Mexican health facility. Our results indicate the need to develop infrastructure, to implement strategies of attention and counselling, and to provide a safe environment in the workplace for women who experience intimate partner violence.

Resumen Objetivo Evaluar el efecto de la violencia de pareja, experimentada en los últimos 12 meses, sobre el riesgo de depresión y la sintomatología depresiva en mujeres adultas. Método Se analizaron los datos de 470 mujeres de la Cohorte de Trabajadores de la Salud de México. El tipo y la gravedad de la violencia de pareja se midieron en los años 2004 y 2011. El evento principal fue el diagnóstico médico de depresión (2011). Un evento secundario fue la sintomatología depresiva (2004 y 2011), evaluada mediante la Escala de Depresión del Centro de Estudios Epidemiológicos (CES-D). El riesgo de depresión y la sintomatología depresiva en relación con la violencia se evaluaron con modelos de regresión de efectos aleatorios logísticos y lineales, respectivamente. Resultados El 41,9% experimentó violencia de pareja en la medición basal. La incidencia de depresión fue del 7,2%. El riesgo de depresión aumentó con la violencia de pareja de cualquier tipo (odds ratio ajustada [ORa]=2,9; intervalo de confianza del 95% [IC95%]: 1,4-6,2) y con las violencias física (ORa=4,3; IC95%: 1,8-10,1), psicológica (ORa=3,1; IC95%: 1,4-6,6) y sexual (ORa=3,1; IC95%: 1,2--8,2). Los síntomas depresivos (CES-D) aumentaron ligeramente con las violencias física y sexual. Conclusiones La violencia de pareja se asoció a un mayor riesgo de depresión en mujeres trabajadoras de una institución de salud de México. Los resultados indican la necesidad de contar con infraestructura, implementar estrategias de atención y consejería, y brindar un ambiente seguro en los lugares de trabajo para quienes sufren violencia de pareja.

Resumen: México enfrenta un enorme desafío para atender los trastornos mentales, con la depresión como uno de los principales contribuyentes a los años de vida ajustados por discapacidad (AVAD) y el aumento de las tasas de suicidio. Estos desafíos se combinan con la escasez de recursos y asignación ineficiente de fondos. Si bien no hay una solución mágica a corto plazo, discutimos experiencias actuales que podrían usarse para brindar una mejor atención primaria en salud mental. Nos centramos en depresión y conducta suicida argumentando que la atención colaborativa es un modelo factible y replicable, enfatizando la capacitación del personal no especializado para que se convierta en administrador de casos y brinde atención primaria en salud mental. México está experimentando un proceso de cambios, incluido el surgimiento de la atención médica universal, por lo que es el momento para que la atención en salud mental sea más transversal, disponible y científicamente probada.

Abstract: Mexico faces an enormous challenge in attending mental health disorders with depression rising as one of the five main contributors to disability adjusted life years (DALYs) and increasing suicide rates. These challenges are coupled with a dearth of resources and an inefficient allocation of the meager funds. While no magical bullet is available to ameliorate this situation in the short term, here we discuss current concepts and experiences that could be used in Mexico to deliver better primary mental health care. We focus on depression and suicidal behavior and argue that collaborative care is a feasible and replicable model, emphasizing the importance of training non-specialized primary care personnel to become case managers and provide primary mental health care. Mexico is currently undergoing a process of changes, including the emergence of universal health care. The time seems right to make mental health care more transversal, widely available and scientifically proven.

Abstract: Objective: To describe and discuss the results of non-pharmacological interventions (NPI) adjuvants in the treatment of depressive symptoms among women with breast cancer (BC). Materials and methods: A systematic review on NPI was performed, which was applied to patients with cancer and depressive symptoms in seven databases. The review was limited from January 1, 2006 to December 31, 2017 and to English, Spanish and Portuguese languages. The medical descriptors used were “breast neoplasm” and “depression”. Results: There are several NPI that are able stimulate the physical or psychosocial dimensions. In this article we propose a classification based on nine identified therapeutic strategies, among which exercise, psychotherapy and yoga with meditation stand out. Conclusions: Based on the available evidence, we concluded that psychotherapy and yoga with meditation reduce depressive symptoms in patients with CaMa. More research is needed to determine the magnitude of the reduction of depressive symptoms, according to their severity, presence of comorbidities and diversity of INF.

Resumo: O presente esforço investigativo visa esquadrinhar discursos reproduzidos pelo episcopado católico em oposição ao lançamento do 3º Programa Nacional de Direitos Humanos (PNDH-3). Ao analisar reações do alto escalão da Igreja, procura-se sondar o repertório que pauta a institucionalidade católica em suas intervenções políticas contemporâneas, que dizem respeito, no mais das vezes, ao campo da moralidade, com especial predileção pela moralidade de cunho sexual. Na trincheira contrária ao PNDH-3, bispos chancelaram seus posicionamentos com o uso de justificativas laicas. Iniciativas episcopais revelaram-se respaldadas por uma gramática fundada no jusnaturalismo e na Constituição. Em suma, adotou-se o repertório dos direitos com a finalidade mesma de cercear direitos.

Abstract: The investigation aims to examine discourses reproduced by the Catholic episcopate in opposition to the launching of the Brazilian 3rd National Human Rights Program (PNDH-3). In analyzing the reactions of the highest echelon of the Church, the idea is to probe the repertoire that guides the Catholic institution in its contemporary political interventions, which, most of the time, concern the field of morality, with special predilection for sexual morality. Opposed to the PNDH-3, bishops backed up their positions with the use of lay justifications. Episcopal initiatives were supported by a grammar based on jusnaturalism and on the Constitution. In sum, the repertoire of rights was adopted with the purpose of restricting rights.

Abstract: Objective: To estimate psychopathology and self-harm behavior of incoming first-year college students, socio-demographic correlates, service use and willingness to seek treatment. Materials and methods: 4 189 male and female incoming first-year students of six universities in four different states of Mexico responded to an online survey with a 79.3% response rate. Results: Almost one in three incoming students has experienced some type of psychopathology; however, only one in five has received treatment. Female, students who are older, whose parents are not married or deceased, and who have a non-heterosexual orientation, no religion or a non-Catholic/Christian religion have greater odds (1.18 - 1.99), whereas those who attend a private university and have a parent with some college education have lower odds (0.68 - 0.75) of experiencing any probable disorder. Conclusions: Substantial unmet need for mental health services combined with reported willingness to use university services suggests an opportunity for the detection, referral, and treatment of incoming students to promote a successful transition.

Resumen: Objetivo: Estimar psicopatologías y autolesiones en universitarios de nuevo ingreso, así como los correlatos sociodemográficos, el uso de servicios y la disposición para recibir tratamiento. Material y métodos: 4 189 estudiantes de nuevo ingreso de seis universidades en cuatro estados contestaron una encuesta en línea con una tasa de respuesta de 79.3%. Resultados: 32.5% han padecido psicopatologías en su vida, pero únicamente 19.5% han recibido tratamiento. Mujeres, estudiantes con una orientación no heterosexual, estudiantes de mayor edad, quienes tienen padres fallecidos o no casados, sin religión o con una religión no católica/cristiana tienen mayor probabilidad de presentar psicopatologías (RM= 1.18-1.99), mientras que aquellos de universidades privadas y cuyos padres tienen estudios universitarios tienen menor probabilidad (RM= 0.68-0.75). Conclusiones: La alta tasa de psicopatologías no tratadas combinada con la disposición reportada de recibir servicios a través de su universidad sugiere una oportunidad para la detección, canalización y tratamiento de alumnos de nuevo ingreso para promover una transición exitosa.

Abstract: Objective: To provide updated information regarding the 12-month prevalence and associated sociodemographic factors for suicide ideation and behavior (plan and attempts) to substantiate preventive programs in Mexico. Materials and methods: Cross-sectional nationally representative survey, conducted during 2016 (n=56 877) among those 12-65 years old living in rural, urban and metropolitan dwellings. Results: The prevalence of suicide ideation in the last 12-months was 2.3%, 0.8% of the sample reported a plan and 0.7% reported a suicide attempt. All three outcomes were about two times more common among females and suicide plan and attempt were less common among the elderly (50-65 years old). Suicide attempts were more common in urban than in rural areas. The state of Tabasco showed an increased prevalence of ideation, plan and attempts when compared to national average rates. Conclusions: Public health measures to diminish and treat suicidal behavior are urgently needed all over the country.

Resumen: Objetivo: Dar información actualizada sobre la prevalencia de 12 meses y los factores sociodemográficos asociados para la ideación y el comportamiento suicida (plan e intentos) para fundamentar programas preventivos en México. Material y métodos: Encuesta transversal representativa a nivel nacional, por sexo y grupos de edad, realizada durante 2016 (n = 56 877) entre personas de entre12 y 65 años de edad en zonas rurales, urbanas y metropolitanas. Resultados: La prevalencia de ideación suicida en los últimos 12 meses fue de 2.3%, 0.8% de la muestra informó un plan y 0.7% informó un intento de suicidio. Los tres resultados fueron aproximadamente dos veces más comunes entre las mujeres y el intento de suicidio fue menos común entre los más viejos (50 a 65 años). Los intentos de suicidio fueron más comunes en las zonas urbanas que en las rurales. El estado de Tabasco mostró una mayor prevalencia de ideas, planes e intentos en comparación con las tasas promedio nacionales. Conclusiones: Es urgente y necesario que existan medidas de salud pública para disminuir y tratar el comportamiento suicida en todo el país.
