RESUMO
INTRODUCTION: Mexico is the country with the highest mortality due to ST-elevation acute myocardial infarction (STEMI), and the IMSS has therefore developed the protocol of care for emergency departments called Código Infarto (Infarction Code). In this article, aspects of translational medicine are discussed with a bioethical and comprehensive perspective. OBJECTIVE: To analyze the Código Infarto protocol from the perspective of translational bioethics. METHOD: A problem-centered approach was carried out through reflective equilibrium (or Rawls' method), as well as by applying the integral method for ethical discernment. RESULTS: The protocol of care for emergency services Código Infarto is governed by evidence-based medicine and value-based medicine; it is guided by a principle of integrity that considers six dimensions of quality for the care of patients with STEMI. CONCLUSION: The protocol overcomes some adverse social determinants that affect STEMI medical care, reduces mortality and global economic disease burden, and develops medicine of excellence with high social reach.

OBJECTIVE: To describe clinical, microbiological and echocardiographic aspects of endocarditis in a specific group of patients without intracardiac devices or underlying structural heart disease. METHOD: Retrospective study, clinical records and echocardiographic reports were reviewed during the period 1997 to 2020. Duke's modified criteria were applied. Statistical analysis: univariate expressed in frequencies, using measures of dispersion and central tendency. RESULTS: 30,000 echocardiographic reports were reviewed, only 1350 had infectious endocarditis as a reason for sending, of which 248 cases were selected. The mean age was 48.1 ± 16.7 years. 140 men (56%) and 108 women (44%). The most frequent echocardiographic sign was vegetation, in 278 (93.60%), and most common location was mitral (35.55%), with a higher number of cases in the right ventricle than expected. The most common systemic disease was kidney disease, in 135 (41.08%). A case of Streptococcus thoraltensis not previously reported in Mexico was identified. CONCLUSIONS: The presence of infectious endocarditis has increased due to invasive in-hospital and drug procedures. Due to their complexity, multidisciplinary teams are indispensable.
OBJETIVO: Describir aspectos clínicos, microbiológicos y ecocardiográficos de endocarditis en un grupo específico de pacientes sin dispositivos intracardiacos ni cardiopatía estructural subyacente. MÉTODO: Estudio retrospectivo en el que se revisaron expedientes clínicos y reportes ecocardiográficos durante el periodo de 1997 a 2020. Se aplicaron los criterios modificados de Duke. Se describió la muestra por edad, sexo, enfermedad sistémica, vegetaciones y agente microbiológico. Se excluyeron pacientes con cardiopatía estructural o Libman-Sacks. Análisis estadístico: univariado expresado en frecuencias, utilizando medidas de dispersión y tendencia central. RESULTADOS: Se revisaron 30,000 reportes ecocardiográficos, de los cuales solo 1350 tenían como motivo de envío endocarditis infecciosa, y de estos se seleccionaron 248 casos. La edad promedio fue de 48.1 ± 16.7 años. Hubo 140 hombres (56%) y 108 mujeres (44%). El signo ecocardiográfico más frecuente fue la vegetación, en 278 (93.60%), y la ubicación más común fue mitral (35.55%), con un número mayor de casos en el ventrículo derecho de lo esperado. La enfermedad sistémica más común fue la enfermedad renal, en 135 (41.08%). Se identificó un caso de Streptococcus thoraltensis no reportado previamente en México. CONCLUSIONES: La presencia de endocarditis infecciosa ha aumentado debido a procedimientos invasivos intrahospitalarios y fármacos. Por su complejidad, los equipos multidisciplinarios son indispensables.

OBJECTIVE: The aim of this study was to show how a geospatial model can be used to identify areas with a higher probability for late-stage breast cancer (BC) diagnoses. METHODS: Our study considered an ecological design. Clinical records at a tertiary care hospital were reviewed in order to obtain the place of residence and stage of the disease, which was classified as early (0-IIA) and late (IIB-IV) and whose diagnoses were made during the 2013-2017 period. Then, they were geolocated to identify the distribution and spatial trend. Subsequently, the pattern of location, i.e. scattered, random and concentrated, was statistically assessed and a geospatial model was elaborated to determine the probability of late diagnoses in the state of Jalisco, Mexico. RESULT: There were 1 954 (N) geolocated BC diagnoses: 58.3% were late. During the five-year period, a southwest-northeast trend was identified, nearly 9.5% of the surface of Jalisco, where 6 out of 10 (n= 751) late- stage diagnoses were concentrated. A concentrated and statistically significant pattern was identified in the southern, central and northern Pacific area of Jalisco, where the geospatial model delimited the places with the highest probability of late clinical stages (p <0.05). CONCLUSION: The geographical differences associated with the late diagnoses of BC suggest it is necessary to adapt and focus the strategies for early detection as an alternative to create a major impact on the population. Reproducible analysis tools were used in other contexts where geolocation data are available to complement public policies and strategies aimed to control BC.

Introduction: Central blood pressure (CBP) is considered a measure of prognostic value for cardiovascular risk. In turn, the aortic pulse wave velocity (PWVAo) and augmentation index (Aix) have been related to arterial stiffness and cardiovascular risk. Controversies exist regarding the reference values in different ethnic groups, ages, and anthropometrics. The objective of this study is to evaluate the CBP and arterial stiffness parameters in a Mexican population by age, gender, and anthropometry. Methods: Between 2015 and 2016, 1009 apparently healthy subjects were recruited in the Instituto Nacional de Cardiología Ignacio Chávez. Using the Arteriograph (TensioMed) equipment with an oscillometric technique, CBP, central pulse pressure (cPP), PWVAo, and Aix were acquired. All results were automatically obtained by computer software version 3.0.0.4. Results: Female sex was prevalent (72%), mean age was 47 ± 12 years; 26% had normal weight, 43% were overweight, and 30% had obesity. The reference values were higher than those reported in other populations. PWVAo and Aix were always found to be higher in females. A central-brachial pressure gradient was observed in < 40 years with lower CBP. Body mass index (BMI) presented a direct and positive correlation with CBP (p < 0.001); however, PWVAo and Aix were not modified. Conclusion: CBP, cPP, PWVAo, and Aix parameters should be considered based on age, gender, and BMI. In Mexican population, CBP and cPP values were higher compared with other previously reported values, especially in women, the elderly, and obese. PWVAo and Aix are higher in older women; however, they are not modified by BMI.
Introducción: La presión central aórtica (PCA) se considera una medida del valor pronóstico. A su vez, la velocidad de la onda del pulso aórtico (VOPA) y el índice de aumento (IA) se han relacionado con la rigidez arterial y riesgo cardiovascular. Existen controversias sobre los valores de referencia en diferentes grupos. El objetivo de este estudio es evaluar estos parámetros en una población mexicana por edad, género y antropometría. Métodos: Entre 2015 y 2016 se reclutaron 1,009 sujetos aparentemente sanos en el Instituto Nacional de Cardiología Ignacio Chávez. Usando el equipo de Arteriograph (TensioMed) con técnica oscilométrica, se adquirieron: PCA, presión de pulso central, VOPA e IA. Todos los resultados fueron obtenidos automáticamente. Resultados: El sexo femenino fue prevalente (72%), edad de 47 ± 12 años; 26% con peso normal, 43% con sobrepeso y 30% con obesidad. Todos los valores fueron superiores a los reportados en otras poblaciones. VOPA e IA siempre fueron más altos en mujeres. Se observó un gradiente de presión central-braquial en < 40 años, con menor PCA. El IMC presentó una correlación directa y positiva con la PCA (p < 0,001), sin embargo, VOPA e IA no se modificaron. Conclusión: Los parámetros de PCA, VOPA e IA deben considerarse en función de edad, género e IMC. En una población mexicana, los valores de PCA fueron más altos en comparación con informados previamente (Europa y Asia), especialmente en mujeres, ancianos y obesos. VOPA e IA son más altos en mujeres mayores; sin embargo, no son modificados por el IMC.

INTRODUCTION: Mexico is the country with the highest mortality due to acute myocardial infarction in adults older than 45 years old according to the OECD (28 vs. 7.5% of the average). The first real-world study, RENASCA IMSS, showed a high-risk population at 65%, but 50% without reperfusion strategies. The aim was to describe the clinical presentation, treatment, and outcomes of acute coronary syndromes at the IMSS. METHODS: RENASCA IMSS is a nation-wide, prospective, longitudinal-cohort study. We include consecutive patients with an Acute Coronary Syndrome diagnosis (ACC/AHA/ESC) admitted in 177 representative hospitals of the IMSS (166 of second level and 11 of third level of attention). In an electronic database clinical, paraclinical, times, reperfusion treatment, complications, and other variables were assessed. Confidentiality was maintained in data and informed consent was obtained. Registrer calibration was performed with more than 80% of the variables and 80% of the cases. RESULTS: From March 1, 2014 to December 25, 2017; 21,827 patients were enrolled presenting an average age 63.2 ± 11.7, 75% men (16,259) and 25% women (5,568). The most frequent risk factors were: hypertension (60.5%), smoking (46.8%), diabetes (45.5%), dyslipidemia (35.3%) and metabolic syndrome (39.1%). STEMI diagnosis was established in 73.2% of the patients and NSTEMI in 26.8%. The STEMI group within the Code Infarction showed an improvement in the reperfusion therapy (34.9% before vs. 71.4% after, p ≤0.0001) and reduction of mortality (21.1 vs. 9.4%, p ≤0.0001); while the NSTEMI group showed high risk set by a GRACE score of 131.5 ± 43.7 vs. 135.9 + 41.7, p ≤0.0001. Mortality was more frequent within the STEMI group (14.9 vs. 7.6%, p ≤0.0001). CONCLUSIONS: RENASCA IMSS study represents the largest Acute Coronary Syndromes real-world study in Mexico, demonstrating that the Mexican population has a high risk. Patients with a STEMI diagnosis were more frequently enrolled and were associated with higher mortality and complications; however, there is improvement in the reperfusion therapy and in mortality with the Code Infarction strategy.
