DEPRESSIVE SYMPTOMS (DS) AND CITIES: A SOCIOECONOMIC PERSPECTIVE FOR THE MEXICAN CASE

Jorge López Martínez Déborah Féber González (2023, [Artículo, Artículo])

This article presents an analysis of the proportion of the population that lives in the 20 top cities of Mexico. Population that suffers from moderate to severe Depressive Symptoms (DS) in relation to urban and socioeconomic factors typical of urban territories and comparing them with people living in rural or non-urban environments that suffers DS. To check this, we generated the Complex Index of Socioeconomic and Urban Conditions (CISUC), based on the Mind the GAPS framework, a model that relates the susceptibility or prevention of mental illness in cities based on urban factors, we also used socioeconomic indicators that exist in Mexican cities. For the construction of the ICCSU database, we used data from the National Health and Nutrition Survey in the years 2006, 2012 and 2018-19 and the data of the Mexican Institute for Competitiveness, A.C. and National Institute of Statistics and Geography in the same years. The results obtained from CISUC were reinforced with the use of a panel data model. The findings that we obtained reveal that there is a more important correlation between cities and people who suffer from moderate to severe DS than in rural areas, a condition that intensifies with the socioeconomic conditions of the population, for example, their socioeconomic stratum, their gender, and present urban marginalization. This allows to generate future discussions about other types of diseases such as anxiety, depression, stress, loneliness, and schizophrenia for large population groups. The panel model yields a lower goodness of adjustment, due to the lack of more time points, however, it points out that improvements in socioeconomic and urban conditions slightly reduce depressive symptoms.

Influence of poverty concerns on demand for healthier processed foods: A field experiment in Mexico City

Marrit Van den Berg Jason Donovan (2023, [Artículo])

Living in poverty can present cognitive biases that exacerbate constraints to achieving healthier diets. Better diets could imply food choice upgrades within certain food categories, such as electing processed foods with an improved nutritional profile. This study evaluated the influence of monetary and health concerns on the willingness to pay (WTP) for healthier processed foods in a low-income section of Mexico City. We employed priming techniques from the scarcity literature, which are applied for the first time to healthier food purchasing behaviours in low-income settings. Our predictions are based on a dual system framework, with choices resulting from the interaction of deliberative and affective aspects. The WTP was elicited through a BDM mechanism with 423 participants. Results showed that induced poverty concerns reduced the valuations of one of the study's healthier food varieties by 0.17 standard deviations. The latter effect did not differ by income level. The WTP for a healthier bread product but one with relatively high sugar and fat content was reduced by induced poverty concerns only among certain consumers without bread purchasing restrictions (78% of the sample). Potential mechanisms were assessed through regression analysis and structural equation modelling. The relationship between poverty concerns and WTP was mediated by increased levels of stress. While we could not rule out impact on cognitive load, it was not deemed a mediator in this study. Our findings signal that improvements in economic and psychological well-being among low-income consumers may aid to increase their demand for healthier processed foods.

Potential impact of prosthetic biomaterials on the periodontium: a comprehensive review.

NATIVIDAD CASTRO ALARCON Artak Heboyan Gustavo Fernandes Norma Samanta Romero Castro (2023, [Artículo])

The success of a prosthetic treatment is closely related to the periodontal health of the individual. The aim of this article was to review and present the importance of prosthetic restorative materials on the condition of the periodontium, the changes that occur in the composition of the subgingival microbiota and the levels of inflammatory markers in gingival crevicular fluid. Articles on the influence of different prosthetic restorative materials on subgingival microbiota and proinflammatory cytokines were searched for using the keywords ¿prosthetic biomaterials¿, ¿fixed prosthesis¿, ¿periodontal health¿, ¿subgingival microbiota¿, ¿periodontal biomarkers¿ and ¿gingival crevicular fluid¿ in PubMed/Medline, Science Direct, Scopus and Google Scholar. The type of material used for prosthesis fabrication together with poor marginal and internal fit can result in changes in the composition of the subgingival microbiota, as well as increased accumulation and retention of dentobacterial plaque, thus favoring the development of periodontal disease and prosthetic treatment failure. Biological markers have helped to understand the inflammatory response of different prosthetic materials on periodontal tissues with the main purpose of improving their clinical application

in patients who need them. Metal-free ceramic prostheses induce a lower inflammatory response regardless of the fabrication method; however, the use of CAD/CAM systems is recommended for their fabrication. In addition, it is presumed that metal-ceramic prostheses cause changes in the composition of the subgingival microbiota producing a more dysbiotic biofilm with a higher prevalence of periodontopathogenic bacteria, which may further favor periodontal deterioration.

Risk, Covid-19 and hospital care in Mexico City: Are we moving toward a new medical practice?

Rubén Muñoz (2023, [Artículo, Artículo])

Covid-19 pandemic has entailed new challenges for health care in the Mexican public health sector, producing changes in clinical practices that are now handling patients infected with covid-19 and also outpatient consultations at tertiary-level care hospitals. Some of these challenges are related to the perception of risk held by physicians regarding the possibility of contracting or transmitting covid-19 during their work,and to the management of risk from the standpoint of biomedical organizational culture linked to the material and symbolic conditions of public health services predating the pandemic. We analyze these issues from a anthropological research based on in-depth interviews to physicians that work with covid-19 patients at “Covid-19 hospitals” or “hybrid hospitals” in Mexico City. Covid-19 has arrived in social relations and perceptions of risk in the arena of health care and involves knowing and transforming some structural and symbolic conditions, resignified with the pandemic, for proper medical care.

Las patologías de los recubrimientos en muros y su repercusión en la salud respiratoria de los usuarios

Rosario Tovar (2023, [Tesis de doctorado])

251 páginas. Doctorado en Diseño Bioclimático.

El nivel de calidad del aire interior (CAI) tiene incidencia directa en la salud humana, por eso, es objeto de estudio del diseño bioclimático, toda vez que éste promueve el aprovechamiento de los factores ambientales para la creación y acondicionamiento de espacios en los que los usuarios experimenten confort y bienestar. Además, de impulsar la construcción con sentido común, en donde prevalezca el uso racional de los recursos y una baja dependencia energética. En la presente tesis se pudieron identificar las propiedades de los materiales más comunes que conforman los recubrimientos de muros (cal, cemento, mortero de cemento y yeso) para reconocer los que mejor se adaptan al clima en la Cd. de México, mismos que según se pudo constatar, contribuyen en el control de algunos factores de riesgo (físico: humedad, químico: tóxicos y biológico: microbios) relacionados con una baja calidad del aire al interior de las viviendas. Tal función mitiga o reduce la aparición de algunos de los padecimientos respiratorios más frecuentes en los usuarios como: alergias, asma, rinitis, gripe y sinusitis. Los análisis a los que fueron sometidos los recubrimientos de cuatro materiales ligantes, permitieron evaluar su desempeño ante factores ambientales semi-controlados (temperatura, humedad relativa y concentración de dióxido de carbono) inherentes al funcionamiento del propio espacio interior y al lugar de emplazamiento del mismo. Obviamente, todos los recubrimientos reaccionaron de forma distinta y acorde con las propiedades físicas y químicas de los materiales presentes en cada uno de ellos. Siendo las variaciones más representativas y satisfactorias, las relacionadas con la permeabilidad y el efecto biocida de los recubrimientos hechos con mezcla de cal. Las patologías que mostraron algunos recubrimientos a lo largo del periodo de monitoreo, debido a la insuficiente gestión de la humedad, al alto desarrollo microbiano y a la naturaleza química del material ligante, fueron criptoeflorescencias, moho, bacterias y desprendimiento/diseminación de partículas; mismas que se consideraron definitorias para establecer que al igual que los seres vivos, los materiales de construcción necesitan rangos higrotérmicos específicos, que permitan su óptimo estado de operación. En apego a lo anteriormente citado, es que se considera conveniente concientizar a la población en temas tan importantes para el bienestar social, como la selección de materiales y -consecuente- conservación de los recubrimientos de muros, no sólo para disminuir los costos de ejecución y mantenimiento, sino para aprovechar sus propiedades, ya que tienen una incidencia directa en lo relacionado con el control de las condiciones ambientales básicas, la regulación de la calidad del aire interior y por ende, en la salud de los usuarios. Dicha labor puede iniciar en la etapa formativa de los profesionales de la construcción, con la intención de normalizar el estudio o correcta selección de los sistemas constructivos en función del clima, pero también identificando la función de cada espacio; para garantizar así, que las propuestas de diseño responderán -satisfactoriamente- a los requerimientos de regulación de la humedad, mediante su absorción, transpiración y/o evaporación.

The level of indoor air quality (IAQ) has a direct incidence on the human health, therefore, is the object of study of bioclimatic design, since it promotes the harnessing environmental factors for the creation and conditioning of spaces in which users experience comfort and well-being. In addition, to encourage construction with common sense, where the rational use of resources and low energy dependence prevail. In this thesis it has been identified the properties of the materials that make up the most common wall coverings (hydrated lime, cement, cement mortar and gypsum) for recognizing those that best adapt to the weather in Mexico City, as it could be verified, they contribute to the control of some risk factors (physical:moisture, chemical:toxics and biological:microbes) related with a low indoor air quality at dwellings. This function mitigates or reduces the appearance of some of the most frequent respiratory ailments in users such as: allergies, asthma, rhinitis, flu and sinusitis. The analyses to which the coatings of four binding materials were subjected, allowed to evaluate their performance in the face of semi-controlled environmental factors (temperature, relative humidity, and carbon dioxide concentration) inherent to the operation of the interior space itself and the place of its location. Obviously, all the coatings reacted differently and according with the physical and chemical properties of the materials in each of them. Being the most representative and satisfactory variations, those related to the permeability and biocidal effect of coatings made with hydrated lime mixture. The pathologies that some coatings showed throughout the monitoring period, due to insufficient moisture management, the high microbial development, and the chemical nature of the binding material, were cryptoefflorescences, mold, bacteria and particle shedding/dissemination; they were defining to establish that in similar way to living beings, building materials need specific hygrothermal ranges, to let them works in an optimal state. According with the above, it is considered convenient to raise awareness among the population on issues as important for social welfare, such as the selection of materials and -consequently- conservation of wall coverings, not only to reduce the costs of execution and maintenance, but to take advantage of their properties, since they have a direct incidence in all related with the control of basic environmental conditions, the regulation of indoor air quality and therefore, in users’ health. This work can begin in the formative stage of construction professionals, with the intention of standardizing the study or correct selection of construction systems depending on the weather, but also identifying the function of each space; to guarantee that the design proposals will respond -satisfactorily- to the requirements of humidity regulation, through its absorption, transpiration and/or evaporation.

“Efecto marzo”: impacto de los nuevos médicos residentes en la salud de los pacientes

Jose Miguel Manrique Velasco (2021, [Tesis de maestría])

Al inicio de los ciclos educativos de los residentes, estos individuos proveen servicios de salud bajo una inadecuada supervisión como un proceso de aprendizaje en el que adquieren nuevas habilidades y conocimientos salud bajo la premisa de “aprender haciendo”, mas la falta inicial de estas expone a los pacientes a una baja calidad de atención que repercute en su salud lo cual no es ético. En consecuencia, la presente tesina evalúa los posibles efectos que tiene la masiva entrada de médicos residentes en México durante el mes marzo. Para lo cual emplea dos métodos con datos administrativos de las Secretaría de Salud. El primero es Diferencias en Diferencias, el cual tiene el objetivo de estimar el contrafactual de forma creíble suponiendo que las características de los individuos son invariantes en el tiempo y que en ausencia de la intervención el grupo de tratamiento seguirá la misma tendencia que el grupo de control. El segundo método es un event study cuyas virtudes son aportar evidencia de una buena identificación del método DID y descomponer el efecto en ventanas de tiempo para analizar como los cambios en el tiempo de la inexperiencia, el burnout, las fallas de coordinación y el learing-by-doing afectan al análisis. Bajo estos diseños se encuentra que hay efectos negativos en la salud de los pacientes a causa de la rotación de residentes los cuales pueden ser explicados por los altos niveles de estrés y cansancio documentados, la falta de práctica real en los procedimientos médicos, la baja supervisión de los residentes y el paradigma educativo de “aprender haciendo”. Además, se observa que estos efectos negativos solo ocurren en las primeras semanas después de la entrada de residentes para después desvanecer su efecto en los meses siguientes, lo cual indica que los residentes logran superar las limitaciones y sobrecarga del trabajo para finalmente otorgar un servicio de salud correspondiente a otros meses.
