Keystone species in an urban environment: Do raptors control the Mexican gray squirrel in Mexico City?

Urbanization has forced animals to respond to novel environments. One of the basic questions in urban ecology is if ecological processes that occur in natural conditions also occur in urban environments. In natural ecosystems, key predators can limit prey abundance and have a widespread effect on trophic levels. Here, we examine a predator-prey interaction in Mexico City, an urban ecosystem where prey can be evaluated in the presence or absence of apex predators. Nearly all original ecosystems in Mexico City have been transformed for human purposes. Many of the green spaces in the city contain populations of the Mexican gray squirrel, a species native to this area. These green spaces are also inhabited by different species of raptors, the most frequent being Harris's hawk, Cooper's hawk, and sharp-shinned hawk. Little is known about the interactions between raptors and squirrels, particularly how different environmental factors influence this ecological relationship. We do know, however, that raptors prey on squirrels. We predicted that in parks where raptors were present, there would be fewer squirrels than in parks where there were no raptors. We studied the relationship between raptors and squirrels using occupancy models, which also allowed us to evaluate environmental factors that affect the presence of both squirrels and raptors. We also tested if the presence of raptors influenced the occupancy probability of squirrels, and vice versa. Lastly, we estimated the abundance of squirrels in parks, both where raptors were present and where they were absent. Contrary to our predictions, in our first two sampling periods we found a positive relationship between the presence of raptors and squirrel abundance, but this relationship was absent during our second two survey periods, which was due to a decline in squirrel abundance in parks where raptors were present. These results suggest that predator-prey interactions occur in urban settings much as they do under natural conditions, but that other factors unique to urbanization can also impact the abundance of raptors and squirrels. Our findings also suggest that raptors might be an effective means of controlling squirrel populations under some conditions.

Algorithm postmastectomy breast reconstruction secondary to breast cancer in a reference center in Mexico City

Background: Postmastectomy breast reconstruction represents a challenge for the plastic surgeon. Contemporary techniques offer numerous options, the reconstructive procedure performed depends on the individual profile of each patient, but will also be influenced by the surgeon's preoperative analysis of their individualized risk profile. Methods: Descriptive, longitudinal, and retrospective study. The reconstructed patients with breast cancer sequelae in the period from May 2023 to May 2024 were included. Based on the review of the literature and the experience of our center, a proposal for a breast reconstruction algorithm was formulated to standardize the ideal surgical treatment according to the case. Results: 119 patients were reconstructed using the algorithm to decide the ideal surgical management. Breast reconstruction was performed in 3 stages: the first stage [1st BRS] (119 patients) consisted of a tissue expander, breast implant ± acellular dermal matrix or autologous pedicled flaps after the mastectomy; in the 2nd BRS (68 patients) the expander was replaced with an implant with or without contralateral symmetrization; and finally in the 3rd BRS (18 patients), the reconstruction of the nipple-areola complex ± neurotization, autologous fat transfer and scar remodeling was performed. Conclusions: The algorithm proposed in this paper provides a guide for making decisions about ideal surgical management according to the clinical characteristics of each subgroup of patients to be reconstructed, improving results by making them reliable and predictable, which positively impacts patient's quality of life.

Structural and sociolectal limits of variability of que in Mexican Spanish noun clefts

This paper investigates the structural and sociolectal limits of the use of non-standard “plain” que instead of the standard relativizer DET+que in Mexican Spanish noun clefts. Although plain que in Spanish noun clefts is considered ungrammatical by reference grammars, we find it in data from Felipe Carrillo Puerto (Quintana Roo, Yucatan) and Mexico City (CDMX). Among the speakers from CDMX, only younger speakers use plain que in our data, suggesting that it might be a more recent innovation in this variety. Among Yucatecan speakers, we find that bilingual speakers (Spanish-Maya) tend to use more plain que than monolingual Spanish speakers, and only bilingual speakers show similar age effects to those found in CDMX, whereas older monolingual Yucatecan speakers use more plain que than younger YS monolinguals. Structurally, plain que is limited to canonical clefts, which we interpret as an indication that clefts with plain que constitute functionally reanalyzed headed relatives. Moreover, we find that those speakers that use plain que do so mostly when the antecedent is specific and carries a determiner. If the antecedent is either non-specific or does not carry a determiner, DET+que is generally preferred.

Difference between Global South cities: Mexico City, Freetown and the global division of urban informal labour

This work pursues a new explanatory framework for understanding some of the variance and homogeneity of informal work between cities in the Global South. Rooted in a materialist approach to informality, it seeks to explain the dynamics of informal work in different urban contexts via a novel application of the global division of labour, termed the global division of urban informal labour. Through a comparative analysis of the urban labour regimes of Freetown, Sierra Leone, and Mexico City, Mexico, the work argues that each city’s respective location within the global capitalist system largely determines the nature of their informal economies. It posits that a city’s informal labour regime is shaped by whether a city’s economy is predominantly defined by financial, industrial or extractive capital, and explores the ramifications of the financialised economy of Mexico City and the extractivist economy of Freetown for shaping informal work in each city. Such an approach attempts not only to explain urban and labour regime variance but also to highlight the essential and foundational nature of informal work in global capitalism today. It also seeks to aid in the task of recentring capitalism and class considerations into understandings of the internal and external dynamics of Global South cities in general.

Cosmic rays, radiocarbon and the beginning of high-energy particle physics: Marietta Blau and the “disintegration stars”

Abstract This brief review describes the discovery of cosmic rays by Victor Hess from the Vienna Radium Institute and the later contribution of Marietta Blau through her observation of “disintegration stars” in photographic emulsion plates exposed to cosmic-ray bombardment. Marietta Blau, a nearly forgotten cosmic-ray pioneer from the Vienna Radium Institute, developed the nuclear emulsion technique for studying nuclear reactions, eventually discovering the disintegration of nuclei through high-energy cosmic rays. Blau survived the Holocaust by escaping to Mexico City from 1939 to 1944. Starting in 1948 at Columbia University, later as a staff member of Brookhaven National Laboratory and then University of Miami, she performed fundamental and original research with nuclear emulsions exposed to 3-GeV protons at the Brookhaven Cosmotron and to 6-GeV protons at the Berkeley Bevatron. Blau returned to Vienna in 1960, where at the Radium Institute a classical β-decay counting facility for radiocarbon dating had been installed, which was finally superseded by the Vienna Environmental Research Accelerator (VERA), a modern versatile accelerator mass spectrometry facility.

World Heritage: features, composition, and tourist significance

It is proved that the idea of world heritage and its conceptual form of legal imple- mentation created a new institution of world heritage in international law. At the end of the 20th century for the first time, the term «world cultural and natural heritage» became widely used to define those natural and cultural objects that are of outstanding importance not only for the people of a certain country but also for all humanity as a whole. Among the main advantages of granting the status of a world heritage site are the following: additional guarantees of preservation and integrity of unique natural and cultural complexes; increasing the prestige of the territories and institutions that take care of them; promoting the promotion of objects included in the List and the development of alternative types of nature use (primarily, ecological tourism); ensuring priority in attracting financial funds for the support of objects of world cultural and natural heritage, first of all, from the World Heritage Fund; promoting the organization of monitoring and control over the state of preservation of natural and cultural objects. Currently, the World Heritage List consists of three categoriesof objects: cultural heritage, natural phenomena, and cultural-natural (mixed) objects. It is noted that every year the number of world heritage sites is steadily increasing, and by 2020 their number has already reached 1,121 sites, including 869 cultural sites, 213 natural sites, and 39 mixed sites. From 1978 until now, the number of nominated objects has constantly increased. However, in order to achieve representativeness, balance, and credibility of the UNESCO Heritage List, certain restrictions on the number of nominations per year have been introduced since 2018. Now their total number cannot exceed 45 nominations per year and only one nomination from the state. They are distributed very unevenly by regions of the world. More than 75% of the world’s cultural heritage is concentrated in Eurasian countries. The countries of America and Africa hold the leadership in the number of natural monuments in the world. The basis of the interest of the countries of the world in the inclusion of objects in the List of World Heritage is the possibility of obtaining profits from the visit of numerous tourists to this cultural or natural attraction. About 225 historic centers of cities around the world are included in the UNESCO Heritage List, including Paris, London, Istanbul, Vienna, Athens, Florence, Venice, St. Petersburg, Krakow, Riga, Jerusalem, Mecca, Mexico City, Quito, Quebec, Rio de Janeiro -Janeiro, etc. It was found that individual objects of cultural heritage are also very popular (the Great Wall of China, St. Peter’s Basilica in the Vatican, the Colosseum, etc.).

Bailando para los santos en el tiempo de Covid-19: respuestas al confinamiento de 2020 en el centro de México

During religious celebrations in the regions of Teotihuacán and Texcoco, northeast of Mexico City, people “dance for a saint,” often to fulfill a promise made after praying for a cure or to give thanks for a favor granted. Based on fieldwork conducted between 2011 and 2019, online interviews, and the tracking of Facebook publications during 2020 and the first months of 2021, this article explores the impact of the coronavirus on devotional dances done during religious celebrations. In particular, it examines the new practices that surfaced during lockdown. Drawing on Jeremy Stolow’s concept of “religion and/as media” (2005), the article demonstrates how during the pandemic, a combination of digital and face-to-face media allowed local Catholic communities to sustain a relationship with their patron saint based on the do ut des principle, “though in a different way.” The conclusions pose several questions about the future of devotional dances and religious celebrations in these regions at the start of the second year of COVID-19 restrictions.

Gaussian modeling with B-splines for spatial functional data on irregular domains

Functional Data Analysis (FDA) has emerged as a powerful framework for datasets that exhibit continuous variation over specified intervals. Unlike traditional methods, FDA treats data as functions, providing a more comprehensive understanding of their behavior and variability. This approach is particularly beneficial for exploring observations collected over time or space. The Spatial Functional Data Analysis (SFDA) incorporates spatial locations as an additional dimension. This integration enhances the ability to model complex associations between curves in the functional domain. Despite progress in analyzing multivariate spatial data, limited attention has been given to SFDA. This study addresses this gap by proposing a Bayesian Gaussian functional approach based on B-splines. The proposal also addresses challenges posed by irregularly spaced observations in the functional domain, a feature rarely considered in the literature. A simulation study is developed to evaluate performance. Finally, results are explored using a relatively novel real dataset from monitoring stations of temperature in Mexico City.

Failure Probability-Based Optimal Seismic Design of Reinforced Concrete Structures Using Genetic Algorithms

Artificial intelligence (AI) has enabled several optimization techniques for structural design, including machine learning, evolutionary algorithms, as in the case of genetic algorithms, reinforced learning, deep learning, etc. Although the use of AI for weight optimization in steel and concrete buildings has been extensively studied in recent decades, multi-objective optimization for reinforced concrete (RC) and steel buildings remains challenging due to the difficulty in establishing independent objective functions and obtaining Pareto fronts. The well-known Non-Dominated Sorting Genetic Algorithm II (NSGA-II) is an efficient genetic algorithm approach for multi-objective optimization. In this work, the NSGA-II approach is considered for the multi-objective structural optimization of three-dimensional RC buildings subjected to earthquakes. For the objective of this study, two function objectives are considered: minimizing total cost and the probability of structural failure, which are obtained via several nonlinear seismic analyses of the RC buildings. Beams and columns’ cross-sectional dimensions are selected as design variables, and the Mexican Building Code (MBC) specifications are imposed as design constraints. Pareto fronts are obtained for two RC-framed buildings located in Mexico City (soft soil sites), which demonstrate the efficiency and accuracy of NSGA-II for structural optimization.

Proposal to estimate the required resources for healthcare

Objective. To present a proposal to estimate healthcare resource requirements for the population with no social security in Mexico City and the domestic projection, including access and coverage. Materials and methods. The gross domestic product percentage for healthcare is calculated using the Medical-Technical Baseline Cost (MTBC) or the Medical Economic Card (MEC) standard according to diagnosis and care treatment for the population with no social security, thus projecting the prospective resource requirements. Results. There is a shortfall of resources for 2024; the prospective per capita for the first level of healthcare is $3,813 and the historical one is $1,933; and the corresponding values for the second level are $4,430 and $3,861. The %GDP-healthcare for Mexico City in 2024 exhibits a 42% difference between the historical and prospective categories. The shortfall of resources for the three levels of healthcare in the entire country is 19%. Conclusions. The prospective budget makes it possible to calculate healthcare resource requirements with a higher degree of certainty and graduality.

Prenatal exposure to phthalates and childhood wheeze and asthma in the PROGRESS cohort

IntroductionPrenatal phthalate exposure may influence lung development and lead to wheezing and asthma in childhood, and these associations may vary by sex. Despite ubiquity of exposure, there is limited epidemiologic data on these associations in Latin America. MethodsWe assessed 593 mother-child dyads enrolled in the Programming Research in Obesity, Growth, Environment, and Social Stressors birth cohort in Mexico City. We quantified 15 phthalate metabolites in 2nd and 3rd trimester maternal urine. Report of ever wheeze, wheeze in the past 12 months (current wheeze) and ever asthma were obtained using a validated survey when children were 4 and 6 years of age. We examined individual associations with modified Poisson models. Mixture effects were assessed using Bayesian Weighted Quantile Sum (BWQS) regression. All models were adjusted for child's sex, maternal age and education at enrollment, and parity. ResultsIn Poisson models, a doubling of mono (carboxy-isononyl) phthalate (MCNP) during the 2nd trimester was associated with higher risk of wheeze (RR: 1.14, 95 % CI: 1.01, 1.29), and asthma (RR: 1.44, 95 % CI: 1.05, 1.97) at 4 years of age. Higher concentrations of the sum of di-isononyl phthalate metabolites (∑DiNP) during the 2nd trimester were also associated with asthma at 4 years of age (RR: 1.30, 95 % CI: 1.04, 1.61). Mixture associations of phthalate metabolite concentrations during the 2nd trimester and asthma at 4 years of age were stronger in males (BWQS, OR: 1.94, 95 % CI: 0.90, 4.60; 90 % CrI: 1.04, 3.73) compared to females (BWQS, OR: 1.23, 95 % CI: 0.56, 2.88; 90 % CrI: 0.61, 2.55). Additionally, we observed stronger inverse associations between prenatal phthalate mixtures during the 3rd trimester and current wheeze at 4 and 6 years of age in females (BWQS, OR: 0.54, 90 % CrI: 0.35, 0.82; OR: 0.45, 90 % CrI: 0.22, 0.84) compared to males (BWQS, OR: 0.95, 90 % Cri: 0.68, 1.35; OR: 0.97, 90 % CrI: 0.59, 1.54). ConclusionsPrenatal phthalate metabolite concentrations were associated with respiratory outcomes in childhood, with some evidence of sex specific effects. Future work investigating phthalate exposure and wheeze trajectories/lung function will be important for understanding how these may predict later disease.

Effect of laparoscopic gastric sleeve vs. laparoscopic gastric bypass in Roux-Y on long-term weight loss in obese mexican population.

Compare the weight loss results between long-term procedures up to 5 years, after undergoing MGL and RYGB in Mexican patients with obesity and associated comorbidity. The most common bariatric surgical procedures worldwide are, laparoscopic gastric sleeve (MGL) and laparoscopic Roux-en-Y gastric bypass (RYGB), as a treatment for weight loss and remission of comorbidity associated with obesity; however, they are the long-term weight loss results in the Mexican population are unknown. Retrospective, observational cohort of patients with obesity undergoing MGL or RYGB in a private hospital Medica Sur, in Mexico City, in the period from 2013 to 2021. Instrumental variables analysis and standardized mean differences were used to calculate outcomes up to 5 years at 5 follow-up visits (S1-S5), at 7 days, 2 months, 6 months, 10 months and 2-5 years after surgery, to compare results of the groups. 104 patients were included in two groups: 31 (30.09%) with MG and 73 (70.87%) with RYGB. The last follow-up (S5), the MG group recorded a mean EW 9.61 kg, EW% 12.72% and EWL% 73.50%, and the RYGB group EW 10.1 kg, EW% 14.72% and EWL% 70.41%. No significant difference was found between groups for long-term EW loss (p = 0.082); however, there is a greater decrease in weight loss in RYGB at 6-12 months compared to MGL.

Characterization of PM2.5 during ACU15 campaign in Mexico City

Mexico City emits several thousands of tons of particle matter from transportation and other economic sectors. We collected PM2.5 samples from January to March 2015. The chemical analyses showed that PM2.5 is made up of 39% organic carbon, 12% elemental carbon, 23% metals (Al, Si, S, P, and K), and 5% heavy metals (Pb, Cr, Mn, Zn, and Hg). Ca and Fe were also present in trace concentrations, probably due to the resuspension of soils. Nitrate, sulfate, and ammonium suggest that the southwest of Mexico City, specifically the sampling site, receives more oxidated pollutants from vehicle emissions than other emissions. The chemical analyses show no significant changes in the composition or concentration of particle matter compared to previous studies.

IRF5 Variants Are Risk Factors for Systemic Lupus Erythematosus in Two Mexican Populations.

Interferon regulatory factor 5 ( IRF5 ) is one of the pivotal genes implicated in systemic lupus erythematosus (SLE) among diverse ethnic groups, including Europeans, Asians, Hispanics, and Africans. Notably, its significance appears particularly pronounced among Hispanic populations. Previous studies have identified several single-nucleotide variants within IRF5 , such as rs2004640G/T, rs2070197T/C, and rs10954213G/A, as associated with susceptibility to SLE among patients from Mexico City. However, the population of Yucatan, located in the Southeast of Mexico and characterized by a greater Amerindian genetic component, remains largely unexplored in this regard. Our study aimed to replicate the observed association between IRF5 variants and susceptibility to SLE among patients from Central Mexico and Yucatan. Furthermore, we investigated the impact of IRF5 rs59110799G/T, a variant that has not been previously studied in SLE individuals. Our study included 204 SLE patients and 160 controls from Central Mexico, as well as 184 SLE patients and 184 controls from Yucatan. All participants were females 18 years and older. We employed a TaqMan assay to detect the presence of the following single-nucleotide variants: rs2004640G/T, rs2070197T/C, rs10954213G/A, and rs59110799G/T. Furthermore, we utilized 2 distinct web tools and databases to predict the potential functional implications of IRF5 variants. In SLE patients from Central Mexico, several IRF5 alleles showed significant associations with the disease following adjustment by the Bonferroni test: the rs2070197C allele (odds ratio [OR], 2.08), the rs10954213A allele (OR, 1.59), and the rs59110799G allele (OR, 1.71). Conversely, among patients from Yucatan, the following alleles showed associations: rs2004640T (OR, 1.51), rs2070197C (OR, 1.62), rs10954213A (OR, 1.67), and rs59110799G (OR, 1.44). Our findings highlight genetic variations between Mexican populations and emphasize the role of IRF5 as a risk factor in SLE patients from both Central Mexico and Yucatan.

Mujeres agricultoras en México: sus realidades y desafíos en el contexto actual

The objective of this article is to analyze the perceptions of female farmers in Mexico to identify their interpretation regarding: (1) the main activities they perform in the field, (2) the use of machinery and agricultural tasks, (3) the valuation of their work, (4) employment opportunities, (5) the resources and support needed to improve production, (6) decision-making in planting, (7) access to training and development, (8) the implications of climate change, (9) the challenges they face in the field, and (10) proposals to promote their participation in the agricultural sector. It is a qualitative study. Information was obtained through semi-structured interviews with eleven women from Hidalgo, Puebla, Estado de Mexico, and the alcaldía de Xochimilco, in Mexico City. It was found that women expressed that their work is not valued; the belief is maintained that they are care providers and that they perform domestic chores; many small-scale producers do not have economic income, and those who work for an employer are paid per day; and they recognize that they earn less than men. Furthermore, the lands are mostly owned by their husbands or rented to men; women express that they do not have the right to inherit the land and that their decision-making is still a reserved matter, coupled with the fact that the field is considered to be masculine. It is concluded that it is necessary to support the Mexican countryside with a gender perspective, thinking that women are the most powerful force of food sovereignty.

Prenatal and early life exposure to fine particulate matter and telomere length in early childhood

BackgroundTelomere length is a biomarker of molecular aging that may be impacted by air pollution exposure starting in utero. We aimed to examine the association between prenatal and early life exposure to fine particulate matter (PM2.5) and leukocyte telomere length (LTL) in children and explore sex differences. MethodsAnalyses included 384 mother–child pairs enrolled in the Programming Research in Obesity, Growth, and Environmental Stressors (PROGRESS) birth cohort in Mexico City. Exposure to PM2.5 was estimated at the residential level using a satellite based spatio-temporally resolved prediction model. Average relative LTL was measured in DNA isolated from blood collected at age 4–6 years using quantitative real-time polymerase chain reaction. Linear regression models were used to examine the association between average PM2.5 across pregnancy, individual trimesters, first postnatal year, and LTL. Models were adjusted for maternal age and education at enrollment, prenatal environmental tobacco smoke exposure, child sex, age, and body mass index z-score at LTL measurement. Effect modification by sex was investigated with interaction terms and stratification. ResultsIn trimester specific models, we found an association between 2nd trimester PM2.5 and elongated LTL (β: 4.34, 95%CI [0.42, 8.42], per 5 μg/m3 increase). There was suggestive effect modification by sex on average 2nd trimester PM2.5 with stronger associations seen in females compared to males (β: 7.12, [95%CI: 0.98, 13.6] and β: 1.43 [95%CI: −3.46, 6.57]) per 5 μg/m3 increase respectively. ConclusionSecond trimester PM2.5 levels were associated with changes in LTL in early childhood. Understanding temporal and sex differences in PM2.5 exposure may provide insights into telomere dynamics over early life.

Functional MRI for the Assessment of Brain Connectivity in Neurodegenerative Diseases: An Observational Study in Mexico City

Introduction: Neurodegenerative diseases are characterized by progressive brain dysfunction and structural changes. Functional MRI (fMRI), a non-invasive imaging technique, offers the potential to assess brain connectivity and identify early biomarkers of these diseases. Methods: This observational study included patients with Alzheimer's disease (AD), Parkinson's disease (PD), and healthy controls in Mexico City. Resting-state fMRI data was acquired, and brain connectivity was analyzed using independent component analysis (ICA) and seed-based correlation analysis (SCA). Results: fMRI revealed altered brain connectivity patterns in AD and PD compared to healthy controls. In AD, decreased connectivity was observed within the default mode network (DMN), while PD patients showed reduced connectivity in the motor network. Conclusion: fMRI provides valuable insights into brain connectivity changes in neurodegenerative diseases. These findings contribute to the development of early diagnostic tools and potential therapeutic targets for AD and PD.

Sustainability and Quality of Life in Marginalized Areas: An Impact Evaluation of a Community Center in Santa Fe, Mexico

The aim of this paper is to present the results of an impact evaluation of a community center in health, capacity building, and digital access, which form an approximation of quality of life, in the population of Santa Fe town in Mexico City, from 2022 to 2024. The methodology is quantitative, using an impact index and the differences in differences (DD) technique. The data were obtained from primary sources with surveys undertaken via questionnaires. The center is operated by a private university and funded by private firms. The results show a positive impact of 0.287127 out of 1 on the weighted impact index, which allows us to consider this program successful in improving the quality of life of the target population. Through impact evaluation, the effectiveness of interventions and opportunities for improvement are identified, fostering collaboration among local actors, including community members, state-run public programs, and community centers. This collaborative effort improves the quality of life, creating a sustainable community wherein each actor addresses specific needs. Impact evaluation plays a crucial role in measuring sustainability because it is a continuous improvement process that, when combined with other actions, enhances the community’s overall well-being.

Contribution of Stroke to Long-Term All-Cause and Cause-Specific Mortality in Mexico City.

Stroke mortality is more common in low-income and middle-income nations such as Mexico. Prognosis data typically rely on short-term hospital follow-ups, revealing high mortality rates due to systemic complications and early recurrence. We aim to explore stroke's long-term impact by examining all-cause and cause-specific mortality. We analyzed data from the Mexico City Prospective Study (1998-2004) with known mortality outcomes until December 2022. Baseline variables were compared between participants who had stroke and nonstroke participants. Cox proportional hazard regression assessed each variable's contribution to overall mortality. Subsequent analysis within the stroke subgroup aimed to identify unique risk factors of mortality, using Cox regression models adjusted for age, sex, and time since stroke. Among 145,537 eligible participants, 1,492 (1.0%) had a history of stroke. Participants who had stroke were older (57.58 vs 50.16, p < 0.001); had lower mean weekly income ($108.24 vs $176.14, p < 0.001); had higher alcohol intake and smoking frequency; and had more frequent comorbidities such as hypertension (48.9 vs 19.3%, p < 0.001), diabetes (23.4 vs 12.9%, p < 0.001), and ischemic heart disease (5.4 vs 1.0%, p < 0.001). They had a significantly increased risk of death from any cause (hazard ratio [HR] 2.59, 95% CI 2.37-2.83, p < 0.001). Deceased participants with stroke were more likely to be male, with a higher prevalence of diabetes, hypertension, and abnormal waist-hip index. Stroke increased the risk of death from cardiac (HR 3.56, 95% CI 3.02-4.19, p < 0.001), renal (HR 2.05, 95% CI 1.58-2.66, p < 0.001), and pulmonary (HR 2.29, 95% CI 1.79-2.92, p < 0.001) causes. This study confirms stroke's association with higher mortality rates, especially from cardiac, renal, and pulmonary causes in Mexico. It underscores the elevated prevalence of cardiovascular comorbidities and adverse socioeconomic profiles among participants who had stroke and those who died with a history of stroke.
