An Evaluation of ¡Haz Espacio Para Papi!, a Culturally Tailored Nutrition and Physical Activity Pilot Program for Mexican-Heritage Fathers.

Fathers are potential leaders of healthy behavior changes in their families. Culturally tailored programs are needed to support behavior changes within families, including Latino families; however, there have been few father-focused nutrition programs for Latino families. This study evaluated the immediate effects of ¡Haz Espacio Para Papi! (Make Room for Daddy!; HEPP), a six-week, father-focused, family-centered program focused on nutrition and physical activity near the Texas-Mexico border. A modified stepped-wedge study design included a treatment group for the HEPP pilot and a wait-listed control group. Pre/post-tests included instant skin carotenoid scores, the self-reported dietary intake of fruits and vegetables (FV), and healthy dietary behavior scores (HDBSs). A 2 × 2 mixed analysis of variance evaluated changes in outcomes across time and between groups for 42 fathers with pre/post-test measures. There were no statistically significant changes in fathers' VM scores and FV intake across time or between groups. Fathers' HDBSs increased across time (p ≤ 0.01, 95% CI [0.23, 1.38]). Age, educational attainment, and the number of children living in the household did not have a significant effect on the program outcomes (p > 0.05). The HEPP program may guide the design of future father-focused nutrition interventions aimed at dietary behavior changes.

Traditional Mexican dietary pattern and cancer risk among women of Mexican descent.

PURPOSE: To examine the association of a traditional Mexican diet score with risk of total, breast, and colorectal cancer among women of Mexican ethnic descent in the Women's Health Initiative (WHI). METHODS: Participants were WHI enrollees who self-identified as being of Mexican descent. Data from food frequency questionnaires self-administered at study baseline were used to calculate the MexD score, with higher scores indicating greater adherence to an a priori-defined traditional Mexican diet (high in dietary fiber, vegetables, and legumes). Incident cancers were self-reported by participants from 1993 to 2020 and adjudicated by trained physicians. We used multivariable-adjusted Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: Among 2,343 Mexican descent women (median baseline age: 59 years), a total of 270 cancers (88 breast, 37 colorectal) occurred during a mean follow-up of 14.4 years. The highest tertile of MexD score was associated with a lower risk of all-cancer incidence (HR: 0.67; 95% CI 0.49-0.91; p-trend: 0.01) and colorectal cancer (HR: 0.38; 95% CI 0.14-0.998; p-trend < 0.05), with each unit increase in the MexD score associated with a 6% lower risk of all-cancer incidence (HR: 0.94; 95% CI 0.88-0.99). There was no statistically significant association with risk of breast cancer. CONCLUSION: Consumption of a traditional Mexican diet was associated with a significantly lower risk of all-cancer incidence and colorectal cancer. Confirmation of these findings in future studies is important, given the prevalence of colorectal cancer and a growing U.S. population of women of Mexican descent.

Disparities in Stage at Presentation Among Hispanic and Latinx Patients With Non-Small-Cell Lung Cancer in the United States.

PURPOSE: Hispanic and Latinx people in the United States are the fastest-growing ethnic group. However, previous studies in non-small-cell lung cancer (NSCLC) often analyze these diverse communities in aggregate. We aimed to identify differences in NSCLC stage at diagnosis in the US population, focusing on disaggregated Hispanic/Latinx individuals. METHODS: Data from the National Cancer Database from 2004 to 2018 identified patients with primary NSCLC. Individuals were disaggregated by racial and ethnic subgroup and Hispanic country of origin. Ordinal logistic regression adjusting for age, facility type, income, educational attainment, comorbidity index, insurance, and year of diagnosis was used to create adjusted odds ratios (aORs), with higher odds representing diagnosis at later-stage NSCLC. RESULTS: Of 1,565,159 patients with NSCLC, 46,616 were Hispanic/Latinx (3.0%). When analyzed in the setting of race and ethnicity, Hispanic patients were more likely to be diagnosed with metastatic disease compared with non-Hispanic White (NHW) patients: 47.0% for Hispanic Black, 46.0% Hispanic White, and 44.3% of Hispanic other patients versus 39.1% of non-Hispanic White patients (P < .001 for all). By country of origin, 51.4% of Mexican, 41.7% of Puerto Rican, 44.6% of Cuban, 50.8% of South or Central American, 48.4% of Dominican, and 45.6% of other Hispanic patients were diagnosed with metastatic disease, compared with 39.1% of NHWs. Conversely, 20.2% of Mexican, 26.9% of Puerto Rican, 24.2% of Cuban, 22.5% of South or Central American, 23.7% of Dominican, and 24.5% of other Hispanic patients were diagnosed with stage I disease, compared with 30.0% of NHWs. All Hispanic groups were more likely to present with later-stage NSCLC than NHW patients (greatest odds for Mexican patients, aOR, 1.44; P < .001). CONCLUSION: Hispanic/Latinx patients with non-small-cell lung cancer were more likely to be diagnosed with advanced disease compared with NHWs. Disparities persisted upon disaggregation by both race and country of origin, with over half of Mexican patients with metastatic disease at diagnosis. Disparities among Hispanic/Latinx groups by race and by country of origin highlight the shortcomings of treating these groups as a monolith and underscore the need for disaggregated research and targeted interventions.

Geographic Origin may Affect Outcomes for Hispanic Patients with Non-Small Cell Lung Cancer in the United States.

BACKGROUND: Social determinants of health thoroughly explored in the literature include insurance status, race, and ethnicity. There are over 50 million self-identifying Hispanics in the United States. This, however, represents a heterogeneous population. We used a national registry to investigate for significant differences in outcomes of Hispanic patients with non-small cell lung cancer (NSCLC) in the Unites states, by geographic region of origin. MATERIALS AND METHODS: We identified a cohort of Hispanic patients in the Unites states with NSCLC for which region of origin was documented within the 2004 to 2016 National Cancer Database (NCDB) registry. This included patients from Cuba, Puerto Rico, Mexico, South and Central America, and the Dominican Republic. We performed multivariate logistic regression modeling to determine whether origin was a significant predictor of cancer staging at diagnosis, adjusting for age, sex, histology, grade, insurance status, and facility type. Race was not included due to a nonsignificant association with stage at diagnosis at the bivariate level in this cohort. Subsequently, we used Kaplan-Meier modeling to identify whether overall survival (OS) of Hispanic patients differed by origin. RESULTS: A total of 12,557 Hispanic patients with NSCLC were included in this analysis. The breakdown by origin was as follows: n = 2071 (16.5%) Cuban, n = 2360 (18.8%) Puerto Rican, n = 4950 (39.4%) Mexican, n = 2329 (18.5%) from South or Central America, and n = 847 (6.7%) from the Dominican Republic. After controlling for age, sex, histology, grade, insurance status and treating facility type, we found that geographic origin was a significant predictor of advanced stage at diagnosis (P = .015). Compared to Cubans, patients of Puerto Rican origin were less likely to present with advanced disease (68.4% vs. 71.9%; OR: 0.82; 95%CI: 0.69-0.98; P = .026). We also identified a significant (log-rank P-value<.001) difference in OS by geographic origin, even at early-stages of diagnosis. Dominican patients with NSCLC exhibited the highest 5-year OS rate (63.3%), followed by patients from South/Central America (59.7%), Puerto Rico (52.3%), Mexico (45.9%), and Cuba (43.8%). CONCLUSION: This study showed that for Hispanic individuals living in the Unites states, region/country of origin is significantly associated with outcomes, even after accounting for other known determinants of health. We suggest that region of origin should be studied further as a potential determinant of outcomes in patients with cancer.

Heterogeneity in Cardiovascular Disease Risk Factors Among Latino Immigrant Subgroups: Evidence From the 2010 to 2018 National Health Interview Survey.

Background The Latino population is a growing and diverse share of the US population. Previous studies have examined Latino immigrants as a homogenous group. The authors hypothesized that there would be heterogeneity in cardiovascular disease risk factors among Latino immigrant subgroups (from Mexico, Puerto Rico, Cuba, Dominican Republic, Central America, or South America) compared with non-Latino White adults. Methods and Results A cross-sectional analysis of the 2010 to 2018 National Health Interview Survey (NHIS) among 548 739 individuals was performed. Generalized linear models with Poisson distribution were fitted to compare the prevalence of self-reported hypertension, overweight/obesity, diabetes, high cholesterol, physical inactivity, and current smoking, adjusting for known confounders. The authors included 474 968 non-Latino White adults and 73 771 Latino immigrants from Mexico (59%), Puerto Rico (7%), Cuba (6%), Dominican Republic (5%), Central America (15%), and South America (9%). Compared with White adults, Mexican immigrants had the highest prevalence of overweight/obesity (prevalence ratio [PR], 1.17 [95% CI, 1.15-1.19]); Puerto Rican individuals had the highest prevalence of diabetes (PR, 1.63 [95% CI, 1.45-1.83]); individuals from Central America had the highest prevalence of high cholesterol (PR, 1.16 [95% CI, 1.04-1.28]); and individuals from the Dominican Republic had the highest prevalence of physical inactivity (PR, 1.25 [95% CI, 1.18-1.32]). All Latino immigrant subgroups were less likely to be smokers than White adults. Conclusions The authors observed advantages and disparities in cardiovascular disease risk factors among Latino immigrants. Aggregating data on Latino individuals may mask differences in cardiovascular disease risk and hinder efforts to reduce health disparities in this population. Study findings provide Latino group-specific actionable information and targets for improving cardiovascular health.

Further delineation of the CWC27-associated spliceosomeopathy: Case report and review of the literature.

Pre-mRNA splicing factors are crucial in regulating transcript diversity, by removing introns from eukaryotic transcripts, an essential step in gene expression. Splicing of pre-mRNA is catalyzed by spliceosomes. CWC27 is a cyclophilin associated with spliceosome, in which genetic defects of its components have been linked to spliceosomopathies with clinical phenotypes including skeletal developmental defects, retinitis pigmentosa (RP), short stature, skeletal anomalies, and neurological disorders. We report two siblings (male and female) of Mexican descent with a novel homozygous frameshift variant in CWC27 and aim to highlight the cardinal features among the previously described 12 cases as well as expand the currently recognized phenotypic spectrum. Both siblings presented with a range of ocular and extraocular manifestations including novel features such as solitary kidney and tarsal coalition in the male sibling, together with gait abnormalities, and Hashimoto's thyroiditis in the female sibling. Finally, we highlight ectodermal involvement including sparse scalp hair, eyebrows and lashes, pigmentary differences, nail dysplasia, and dental anomalies as a core phenotype associated with the CWC27 spliceosomopathy.

Association between rs61764370, rs9266, and rs140080026 polymorphisms of the KRAS gene and breast cancer risk in a Mexican population.

OBJECTIVE: Polymorphisms of the KRAS gene have been shown to be associated with cancer. However, their association with breast cancer (BC) has been inconsistent. The purpose of this study was to determine the frequency with which the rs61764370, rs9266, and rs140080026 polymorphisms of the KRAS gene are associated with BC in patients of the Mexican population. PATIENTS AND METHODS: The rs61764370 A>C or T>G and rs140080026 A>G polymorphisms were determined by Polymerase Chain Reaction (PCR), and the rs9266 A>G polymorphism was determined by DNA sequencing of healthy Mexican subjects and BC patients. RESULTS: We observed that 78% of BC patients are overweight and/or obese, 57% have metastatic lymph nodes, 64% have luminal A/B cancer subtypes, and 61% have stage III-IV cancer. The rs61764370 polymorphism was associated with BC susceptibility when the BC patients and the control group were compared for the AC genotype (p = 0.020), AC vs. AA genotypes (heterozygous model: p = 0.016), AC/CC genotype (dominant model: p = 0.002), and the C allele (p = 0.007). The AC/CC genotype (p = 0.018; rs61764370) and AG/GG genotype (p = 0.005; rs9266) were associated with age in BC patients ≥50 years old. The AC/CC (rs61764370) and AG/GG (rs9266) genotypes were classified by molecular subtype, TNM stage, miscarriage, lymph node metastasis, ductal type, and Ki-67. These classifications were also associated with BC patients, indicating that these factors may significantly contribute to BC risk. The AAA (OR 0.65, 95% CI 0.43-0.98, p = 0.039) and CAA (OR 3.25, 95% CI 1.13-9.36, p = 0.021) haplotypes were also associated with BC susceptibility. In addition, 94 polymorphisms were identified on the 3'UTR of the KRAS gene GRCh 38/hg3 (25,209,490-25,209,122) in BC (n = 112) and control (n = 113) samples. However, 92 of these polymorphisms have only expressed the major allele (wild-type allele). CONCLUSIONS: The rs61764370 polymorphism in the KRAS gene was associated with BC susceptibility in the Mexican population. The dominant model of the rs61764370 and rs9266 polymorphisms (classified by molecular subtype, miscarriage, TNM stage, lymph node metastasis, and Ki-67) could significantly contribute to BC risk in patients ≥50 years. The CAA haplotype could significantly contribute to BC risk in the Mexican population analyzed.

Cross-sectional pilot study to assess primary healthcare workers' knowledge of nonalcoholic fatty liver disease in a marginalized community in Mexico.

The registered incidence of nonalcoholic fatty liver disease (NAFLD) in primary healthcare centers is lower than expected, suggesting a lack of awareness by primary care healthcare professionals. The implementation of educational tools for healthcare workers has been found to increase timely referral and treatment of patients. We aimed to determine healthcare workers' knowledge of NAFLD to identify their educational needs in one marginalized region. We performed a cross-sectional survey of 261 healthcare professionals in Tlapa de Comonfort, Guerrero, Mexico from October 2019 to December 2019. We created a questionnaire that assessed domains most relevant to NAFLD knowledge. Two hundred and forty-six questionnaires were completed. Of the respondents, 38.3% were nurses and 63.4% were women. Most nurses identified NAFLD as a prevalent (89%) and preventable (93%) disease. Hypertension (33%) and obesity (84%) were recognized as risk factors. The associations between NAFLD and cancer, cirrhosis and cardiovascular disease were identified by 53%, 67% and 72% of respondents, respectively. The largest gaps were found in diagnostic workup, therapeutic approach and the current treatments. We identify modifiable knowledge gaps in NAFLD. Educational strategies for primary care workers could enhance the identification of patients with NAFLD and prevent complications.

Differences in outcomes after emergency general surgery between Hispanic subgroups in the New Jersey State Inpatient Database (2009-2014): The Hispanic population is not monolithic.

BACKGROUND: Our aim was to examine differences in clinical outcomes between Hispanic subgroups who underwent emergency general surgery (EGS). METHODS: Retrospective cohort study of the HCUP State Inpatient Database from New Jersey (2009-2014), including Hispanic and non-Hispanic White (NHW) adult patients who underwent EGS. Multivariable analyses were performed on outcomes including 7-day readmission and length of stay (LOS). RESULTS: 125,874 patients underwent EGS operations. 22,971 were Hispanic (15,488 with subgroup defined: 7,331 - Central/South American; 4,254 - Puerto Rican; 3,170 - Mexican; 733 - Cuban). On multivariable analysis, patients in the Central/South American subgroup were more likely to be readmitted compared to the Mexican subgroup (OR 2.02; p < 0.001, respectively). Puerto Rican and Central/South American subgroups had significantly shorter LOS than Mexican patients (Puerto Rico -0.58 days; p < 0.001; Central/South American -0.30 days; p = 0.016). CONCLUSIONS: There are significant differences in EGS outcomes between Hispanic subgroups. These differences could be missed when data are aggregated at Hispanic ethnicity.

Ethnic and border differences on blood cancer presentation and outcomes: A Texas population-based study.

BACKGROUND: The Texas/Chihuahua (US/Mexico) border is a medically underserved region with many reported barriers for health care access. Although Hispanic ethnicity is associated with health disparities for many different diseases, the population-based estimates of incidence and survival for patients with blood cancer along the border are unknown. The authors hypothesized that Hispanic ethnicity and border proximity is associated with poor blood cancer outcomes. METHODS: Data from the Texas Cancer Registry (1995-2016) were used to investigate the primary exposures of patient ethnicity (Hispanic vs non-Hispanic) and geographic location (border vs non-border). Other confounders and covariates included sex, age, year of diagnosis, rurality, insurance status, poverty indicators, and comorbidities. The Mantel-Haenszel method and Cox regression analyses were used to determine adjusted effects of ethnicity and border proximity on the relative risk (RR) and survival of patients with different blood cancer types. RESULTS: Hispanic patients were diagnosed at a younger age than non-Hispanic patients and presented with increased comorbidities. Whereas non-Hispanics had a higher incidence of developing blood cancer compared with Hispanics overall, Hispanics demonstrated a higher incidence of acute lymphoblastic leukemia (RR, 1.92; 95% CI, 1.79-2.08; P < .001) with worse outcomes. Hispanics from the Texas/Chihuahua border demonstrated a higher incidence of chronic myeloid leukemia (RR, 1.28; 95% CI, 1.07-1.51; P = .02) and acute myeloid leukemia (RR, 1.17; 95% CI, 1.04-1.33; P = .0009) compared with Hispanics living elsewhere in Texas. CONCLUSIONS: Hispanic ethnicity and border proximity were associated with a poor presentation and an adverse prognosis despite the younger age of diagnosis. Future studies should explore differences in disease biology and treatment strategies that could drive these regional disparities.

The Body in the Mirror: Breast Cancer, Liminality and Borderlands.

Breast cancer is the most common cancer among women worldwide, and has a high mortality rate in northern Mexico. Its high rates present one of the principal health challenges of the California-Baja California border region. We employed "entangled" ethnography and interpretative phenomenological methods to explore breast cancer experiences among a group of Mexican immigrant women living on the US side of this border. We explore their trajectory from biographical disruption to biographical renewal. The entangled ethnographic approach includes reflections of the first author's experience as a genetic breast cancer survivor.

"It's Worse to Breathe It Than to Smoke It": Secondhand Smoke Beliefs in a Group of Mexican and Central American Immigrants in the United States.

This analysis describes beliefs about secondhand smoke and its health effects held by Mexican and Central American immigrants in North Carolina. Data from 60 semistructured, in-depth interviews were subjected to saliency analysis. Participant discussions of secondhand smoke centered on four domains: (1) familiarity and definition of secondhand smoke, (2) potency of secondhand smoke, (3) general health effects of secondhand smoke, and (4) child health effects of secondhand smoke. Secondhand smoke was generally believed to be more harmful than primary smoke. Mechanisms for the potency and health effects of secondhand smoke involved the smell of secondhand smoke, secondhand smoke being an infection and affecting the immune system, and personal strength being protective of secondhand smoke. Understanding these health beliefs informs a framework for further health education and intervention to reduce smoking and secondhand smoke exposure in this vulnerable population.

Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer Is Associated with Indigenous American Ancestry in Latin American Women.

Women of Latin American origin in the United States are more likely to be diagnosed with advanced breast cancer and have a higher risk of mortality than non-Hispanic White women. Studies in U.S. Latinas and Latin American women have reported a high incidence of HER2 positive (+) tumors; however, the factors contributing to this observation are unknown. Genome-wide genotype data for 1,312 patients from the Peruvian Genetics and Genomics of Breast Cancer Study (PEGEN-BC) were used to estimate genetic ancestry. We tested the association between HER2 status and genetic ancestry using logistic and multinomial logistic regression models. Findings were replicated in 616 samples from Mexico and Colombia. Average Indigenous American (IA) ancestry differed by subtype. In multivariate models, the odds of having an HER2+ tumor increased by a factor of 1.20 with every 10% increase in IA ancestry proportion (95% CI, 1.07-1.35; P = 0.001). The association between HER2 status and IA ancestry was independently replicated in samples from Mexico and Colombia. Results suggest that the high prevalence of HER2+ tumors in Latinas could be due in part to the presence of population-specific genetic variant(s) affecting HER2 expression in breast cancer. SIGNIFICANCE: The positive association between Indigenous American genetic ancestry and HER2+ breast cancer suggests that the high incidence of HER2+ subtypes in Latinas might be due to population and subtype-specific genetic risk variants.

Prevalence of human papillomavirus in the oral cavity of an indigenous community from Southwest México.

Human papilloma virus (HPV) is a DNA virus associated with the development of cervical, penile, anal, vulvar, and oral cancers. In recent years, there has been an increase in oral cancer, which could be due to changes in sexual behavior in the general population. In México, there is scarce information on this regard, which prompted us to study HPV infection prevalence in the oral cavity of an indigenous community from the municipality of Siltepec, Chiapas, Mexico. Oral samples from 198 individuals were obtained with cytobrush for virus detection by nested PCR, using MY09/MY11 and GP5+/GP6+ primers, and positive samples were sequenced for HPV genotyping. We observed 12.1% HPV infection prevalence, which depended on gender, number of sexual partners, lack of using condoms, and oral sex practices. In contrast, no significant association between HPV infection and tobacco or alcohol consumption was detected. Furthermore, sequencing analyzes were performed where HPV-13 (21/24), -16 (2/24), -32 (1/24), -81 (1/24), and -83 (1/24) were evidenced and HPV-16 European/Asian and Asian/American E6 variants identified. These results demonstrated an important prevalence of HPV infection in the oral cavity of a Mexican indigenous community, where the predominant genotypes were associated with benign pathologies, and showed that high-risk genotype variants derived from different lineages.

Factores de riesgo cardiovascular en Estados Unidos y México: comparación de los estudios HABLE y ENASEM / Cardiovascular risk factors in Mexico and the United States: a comparative cross-sectional study between the HABLE and MHAS participants

Resumen Introducción: En Estados Unidos se dispone de información acerca de la población mexicoamericana por el Estudio de Salud y Envejecimiento del Cerebro en Latinos Mayores (HABLE); en México se dispone de los resultados del Estudio Nacional de Salud y Envejecimiento en México (ENASEM). Objetivo: Comparar la prevalencia de factores de riesgo cardiovascular entre hombres y mujeres de HABLE y ENASEM. Método: Se analizó transversalmente la prevalencia de hipertensión, diabetes, hipercolesterolemia y obesidad abdominal en 559 participantes de HABLE y se comparó con datos de 13 663 participantes del ENASEM. La comparación se realizó mediante t de Student y chi cuadrada, según el tipo de variable. Resultados: El análisis demostró que la prevalencia de hipertensión (50 %, IC 95 % = 41.8-51.8), diabetes (35.5 %, IC 95 % = 27.6-43.8) y obesidad abdominal (59.3 %, IC 95 % = 50.5-68.1) fueron significativamente mayores en hombres del HABLE, mientras que las mujeres presentaron una prevalencia más elevada de diabetes (36.8 %, IC 95 % = 32.2-41.5) y obesidad abdominal (89.6 %, IC 95 % = 86.6-92.5). La hipercolesterolemia tuvo una prevalencia más elevada en mujeres del ENASEM (53.3 %, IC 95 % = 50.3-56.2). Conclusión: La prevalencia de factores de riesgo cardiovascular fue mayor en mexicoamericanos participantes del HABLE, que en mexicanos participantes del ENASEM.

Abstract Introduction: In the United States, information on the Mexican-American population is available through the Health and Aging Brain among Latino Elders (HABLE) study; in Mexico, the results of the Mexican Health and Aging Study (MHAS) are available. Objective: To compare the prevalence of cardiovascular risk factors between men and women of the HABLE and MHAS studies. Method: The prevalence of hypertension, diabetes, hypercholesterolemia and abdominal obesity was transversely analyzed in 559 HABLE participants and compared with data from 13,663 MHAS participants. The comparison was made using Student’s t-test and the chi-square test, according to the type of variable. Results: The analysis showed that the prevalence of hypertension (50 %, 95 % CI = 41.8-51.8), diabetes (35.5 %, 95 % CI = 27.6-43.8) and abdominal obesity (59.3 %, 95 % CI = 50.5-68.1) were significantly higher in HABLE males, whereas females had a higher prevalence of diabetes (36.8 %, 95 % CI = 32.2-41.5) and abdominal obesity (89.6 %, 95 % CI = 86.6-92.5). Hypercholesterolemia had a higher prevalence in MHAS females (53.3%, 95% CI = 50.3-56.2). Conclusion: The prevalence of cardiovascular risk factors was higher in Mexican American HABLE participants, than in Mexican MHAS participants.

Día del Dentista, según la cosmovisión maya / Day of the dentist, according to the Mayan cosmovision

El día del odontólogo tradicionalmente se festeja el 9 de febrero, en conmemoración a Santa Apolonia, quien el 9 de febrero del año 248 d.C., por no renunciar a su fe cristiana, es martirizada quitándole los dientes. Sin embargo, existe una historia de origen maya, escrita en el Popol Vuh, la de Vucub Caquix, ave mítica antropomorfa, a quien se le extraen los dientes. Este hecho acontece antes de la creación del mundo, el 13 de agosto del año 3114 a.C. Este hallazgo surge al relacionar el Popol Vuh con las imágenes representadas en la vasija maya K 1226, la estela 25 de Izapa y las inscripciones de la estela de Cobá, Quintana Roo. Por lo anterior, proponemos que este acontecimiento podría tomarse en cuenta para conmemorar en México el día del dentista el 13 de agosto, puesto que ello sería una forma de revalorar y reafirmar nuestra identidad prehispánica (AU)

The dentist's day is traditionally celebrated on February 9, in commemoration of Santa Apolonia, who on February 9 of the year 248 AD, for not giving up her Christian faith, is martyred by taking her teeth. However, there is a story of Mayan origin, written in Popol Vuh, that of Vucub Caquix, a mythical anthropomorphic bird, whose teeth are extracted. This fact occurs before the creation of the world, on August 13, 3114 BC. This finding arises when the Popol Vuh is related to the images represented in the Mayan vessel K 1226, stela 25 of Izapa and the inscriptions of the stela de Cobá, Quintana Roo. Therefore, we propose that this event could be taken into account to commemorate August 13, as the day of the dentist, as a way to revalue and reaffirm our pre-Hispanic identity (AU)
