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.

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.

There is speculation about moon phases influencing animal reproductive performance. A study was carried out to shed light on the influence of moon phases on estrus presentation, pregnancy rate, calving presentation, and offspring sex in cows from the Mexican dry tropical region. The reproductive data of 580 crossbred cows from 2010 to 2021 was organized according to reproductive events (estrus presentation, gestation, calving presentation, and offspring sex) occurrence during moon phases (new moon, first quarter, full moon, and last quarter). The data were analyzed by Chi-squared test and logistic regression. The full moon reduced the estrus presentation (p0.05). It is concluded that the full moon reduces estrus presentation in crossbred cows. Moon phases do not influence the gestation, calving presentation, and offspring sex.

El ostión Magallana gigas es ampliamente cultivado a nivel mundial. En Baja California, México, los laboratorios de reproducción deben acondicionar ostiones para su maduración y producción de gametos, y abastecer de semilla a los productores. En nuestro laboratorio, Sistemas de Recirculación Acuícola (SRA), con control del sistema CO2-Carbonatos (SRA-R) o sin control (SRA-C), han permitido madurar ostiones M. gigas y M. sikamea. Recientemente, los ostiones M. gigas acondicionados en nuestros SRA no maduraron, y algunos presentaron prevalencia de polidóridos (PP), poliquetos parásitos excavadores de concha. Para comprender la condición de los ostiones, evaluamos el efecto del SRA y de la PP sobre la expresión relativa de ocho genes asociados a biomineralización (VpATP y Tyr), inmunidad innata (P38, PGRP-L y TLR2) y reproducción (GnRH-RI, Vasa-like y SP1b) de M. gigas en dos etapas del acondicionamiento, 18 °C y 24 °C. La PP se determinó por la presencia de ampollas en la concha. Mediante RT-qPCR se determinó la expresión de VpATP, Tyr, P38, PGRP-L y TLR2 en el manto, y de GnRH-RI, Vasa-like y SP1b en la gónada. La expresión relativa se evaluó con un enfoque estadístico basado en un análisis Bayesiano de dos vías y comparaciones múltiples, p-valor significativo < 0.05 y corrección de Bonferroni. En 18 °C, la expresión de VpATP, Tyr, TLR2 y P38 fue mayor en ostiones con PP (CPP) que sin PP (SPP). En contraste, la expresión de GnRH-RI, Vasa-like y SP1b fue menor CPP que SPP. Dentro del SRA-C, en los ostiones CPP hubo mayor expresión de Tyr y menor expresión de Vasa-like y SP1b, respecto a los ostiones SPP. Esto sugiere que la PP induce la reparación de la concha y las respuestas inmune e inflamatoria en el manto mientras que en la gónada reduce el desarrollo de las células germinales. En 24 °C, en el SRA-R hubo menor expresión de SP1b respecto del SRA-C y sugiere menor división celular en la gónada. En conclusión, el SRA-R y la PP afectaron el balance energético del ostión japonés, limitando la energía y reflejando menor esfuerzo reproductivo en los ostiones del SRA-R al final del acondicionamiento reproductivo.
The Japanese oyster (Magallana gigas) is highly cultured worldwide. In Baja California, Mexico, the reproduction laboratories must condition oysters to maturity and have gametes to supply oyster seeds to producers. In our laboratory, recirculating aquaculture systems (RAS), with control of the CO2-Carbonate system (RAS-R) and without this control (RAS-C), have allowed oysters M. gigas and M. sikamea to mature. Recently, the M. gigas oysters conditioned in our RAS did not mature, and some have the prevalence of Polidorids (PP), shell-boring polychaete parasites. To understand the oysters' condition, we evaluated the effect of RAS and the PP on the relative expression of eight genes associated with biomineralization (VpATP and Tyr), innate immunity (P38, PGRP-L, and TLR2), and reproduction (GnRH-RI, Vasa-like, and SP1b) of M. gigas at two phases of broodstock conditioning, 18 °C and 24 °C. The PP was determined by mud blisters at the inner oyster shell. RT-qPCR determined the expression of VpATP, Tyr, p38, PGRP-L, and TLR2 in the mantle tissue and GnRH-RI, Vasa-like, and SP1b in the gonad tissue. The relative gene expression was evaluated by a Bayesian statistics frame based on a two-way and multiple comparison analysis, with significant p-value < 0.05 and Bonferroni correction. At 18 °C, there was higher expression of VpATP, Tyr, TLR2, and P38 in oysters with PP (WPP) than without PP (WOPP). In contrast, the expression of GnRH-RI, Vasa-like, and SP1b was less WPP than WOPP. It suggests that the PP induces shell repair and immune and inflammatory responses in mantle tissue, while in gonad tissue, it reduces the development of germinal cells. At 24 °C, in RAS-R, there was less expression of SP1b respect RAS-C, and it suggests less cellular division in the gonad. In conclusion, the RAS-R and the PP affect the energetic balance of the Japanese oyster, limiting the energy and reflecting less reproduction effort in oysters from RAS-R at the end of broodstock conditioning.
