Clinical Efficacy of Modified Banxia Xiexintang Combined with Vedolizumab in Treatment of Crohn's Disease with Syndrome of Cold and Heat in Complexity / 中国实验方剂学杂志

ObjectiveTo evaluate the clinical efficacy of modified Banxia Xiexintang combined with vedolizumab （VDZ） in the treatment of active moderate to severe Crohn's disease （CD） with the syndrome of cold and heat in complexity and the effect of the therapy on intestinal flora. MethodEighty patients were randomized based on the random number table method into a control group （40 cases） and an observation group （40 cases）. The control group was treated with VDZ， and the observation group was treated with modified Banxia Xiexintang （1 bag per day） combined with VDZ. The treatment in both groups lasted for 14 weeks and the follow-up lasted until the 52th weeks. The CD activity index （CDAI）， CD simplified endoscopic score （SES-CD）， inflammatory bowel disease questionnaire （IBDQ） score， and syndrome score of cold and heat in complexity were assessed before treatment， after treatment， and at the end of follow-up. The levels of hemoglobin （HGB）， hematocrit （HCT）， albumin （ALB）， C-reactive protein （CRP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， interleukin-17 （IL-17）， and fecal calprotectin （FC） were measured before and after treatment. Intestinal flora was examined before and after treatment. The safety of the therapy was evaluated. ResultCompared with those before treatment， the scores of CDAI， SES-CD， and the syndrome of cold and heat in complexity decreased （P<0.05） and the IBDQ score increased after treatment （P<0.05）. Compared with those before treatment， the scores of CDAI， SES-CD， and the syndrome of cold and heat in complexity increased （P<0.05） and the IBDQ score decreased （P<0.05） at the end of follow-up. After treatment and at the end of follow-up， the observation group had lower scores of CDAI， SES-CD， and syndrome of cold and heat （P<0.05） and higher IBDQ score （P<0.05） than the control group. Moreover， the observation group had higher clinical remission rate（χ2=4.381，3.962） and response rate（χ2=5.541，4.306） and lower non-response rate（χ2=6.646，4.306） than the control group at the two time points （P<0.05）. The endoscopic remission rate（χ2=4.072，3.985） and response rate（χ2=4.528，5.161） in the observation group were higher than those in the control group （P<0.05）. After treatment， the HGB， HCT， and ALB levels in both groups elevated， and the observation group had higher levels than the control group （P<0.05）. The treatment in both groups lowered the levels of CRP， IL-6， TNF-α， IL-17， and FC （P<0.05）， and the observation group had lower levels of CRP， IL-6， TNF-α， IL-17， and FC than the control group after treatment （P<0.05）. The relative abundance of Bifidobacterium， Lactobacillus， and Prevotella increased （P<0.05）， while that of Proteus， Klebsiella， and Enterococcus decreased （P<0.05） in the two groups after treatment. Moreover， the changes in the relative abundance of these bacteria in the observation group were more obvious than those in the control group （P<0.05）. No adverse reactions related to the modified Modified Banxia Xiexintang were observed during the study period. ConclusionModified Banxia Xiexintang combined with VDZ can play a synergistic role and has good short-term and long-term efficacy. This therapy can improve the nutritional status， regulate intestinal flora， and reduce inflammatory injury in the treatment of moderate to severe active CD patients with the syndrome of cold and heat in complexity without causing severe adverse reactions.

Inductores de ferroptosis para el tratamiento del cáncer

Introducción: La ferroptosis es un proceso no apoptótico de muerte celular regulada que depende de la presencia de iones hierro en el medio intracelular. Se caracterizada por la acumulación de especies reactivas de lípidos oxidados y radicales libres en las membranas celulares.

Conclusión: La metacognición es el proceso mental más sensible en el proceso educativo que trasciende aplicando el pensamiento complejo.

Introduction: Metacognition is the process through which the student becomes aware of what he learns, but how can we expand this concept from the emerging paradigm of complexity, if we relink awareness to the application of complex thinking. Metacognition applied with elements of complex thinking is called metacomplexity, which is a superior process where we become aware of complexity to learn and teach, it will imply levels of reality and ways of applying complexity in educational processes. Objective: To theoretically review the concept of metacognition in order to deepen the subject taking into consideration the concept of classroom social mind in Education. Method: Theoretical review of the author's publications, it is a cross-sectional, retro-prospective, non-experimental study. Discussions: The process of continuity of metacomplexity will therefore be the social mind classroom as the most creative process that a student can develop in order to solve educational or daily life problems. Conclusion: Metacognition is the most sensitive mental process in the educational process that transcends by applying complex thinking.

Teoría de la complejidad y los sistemas de salud / Complexity theory and health systems

En la investigación en salud es todavía poco frecuente el uso de la Teoría de la Complejidad y de la Fractalidad (más aún en tópicos no relacionados directamente con la biología molecular o con la clínica). La complejidad nos propone complementar con propuestas desde nuevas perspectivas el pensamiento lineal y cuantitativo predominante todavía en la metodología de producción del conocimiento científico. El estudio de los sistemas de salud necesita un enfoque que se aparte de la linealidad, lo rígido y lo direccional, dado que los mismos son sistemas complejos en los que el todo es más que la simple suma de sus partes. La crisis global generada ante la pandemia por COVID-19 nos puso frente a la oportunidad (y a la obligación) de repensar tanto nuestra praxis cotidiana como nuestra forma de producir conocimiento (AU)

In health research, the use of the Complexity and Fractality Theory is still infrequent (even more so in topics not directly related to molecular or clinical biology). The complexity proposes us to complement with proposals from new perspectives the linear and quantitative thinking still predominant in the methodology of production of scientific knowledge. The study of health systems needs an approach that moves away from linearity, rigidity and direction, since they are complex systems in which the whole is more than the simple sum of its parts. The global crisis generated by the COVID-19 pandemic presented us with the opportunity (and the obligation) to rethink both our daily praxis and our way of producing knowledge (AU)

Tuina (Chinese massage) is an important part of Traditional Chinese Medicine. It is a simple and inexpensive technique, and has shown effectiveness for muscle and bone diseases, visceral diseases, gynecological diseases, and common diseases in children. This paper aims to analyze the factors influencing the effects of Tuina. The factors included the aspects of diagnosis, treatment, prognosis, patient factors and doctor-patient communication. During the treatment of Tuina, doctors should carry out good doctor-patient communication, properly evaluate and exam patients, and clarify diagnosis, take appropriate Tuina techniques according to the patients' constitution, health condition, and comorbidity. Only in such way, could Tuina achieve effectiveness and safety.

A Ventricular Fibrillation Recognition Method Based on Random Forest and BP Neural Network / 中国医疗器械杂志

Ventricular fibrillation is the most common pathophysiological mechanism leading to cardiac arrest. If cardiac arrest can be rescued in time, the survival rate of patients can be greatly improved. Therefore, rapid and accurate identification of ventricular fibrillation is extremely important. This paper proposes an automatic detection algorithm for ventricular fibrillation based on random forest and BP (back propagation) neural network. Pass the ECG signal through a 6 s moving window, calculate 6 kinds of characteristic parameters according to the time-frequency domain information of the signal, use these 6 kinds of characteristic parameters as the input of the classifier, carry out classification and test, and give the authoritative experts in the database. A total of 44 cases of related data were used to evaluate the method. The results show that using the ten-fold cross-validation method, the accuracy of classification of ventricular fibrillation in the CU database (Creighton University Ventricular Tachyarrhythmia Database) and the AHA database (the American Heart Association Database) has reached 96.38% and 99.45%, which has certain applicability.

Intervención ambulatoria basada en categorización por complejidad en neurorehabilitación

Introducción: Existen múltiples factores que dificultan el acceso a la terapia de alta intensidad y pocos estudios han considerado la efectividad de la Neurorehabilitación motora ambulatoria basada en atención directa al paciente, ejercicios guiados por el cuidador y entrenamiento de autogestión en rehabilitación. Objetivo: Evaluar el efecto en los resultados funcionales, de movilidad y equilibrio en los pacientes atendidos por un programa de Neurorehabilitación motora ambulatoria categorizados por complejidad en rehabilitación en el Hospital Carlos van Buren de Valparaíso. Material y Método: Estudio de cohorte retrospectivo. Se analizaron los registros de los pacientes atendidos en 2018 en el policlínico de Neurorehabilitación del Hospital Carlos van Buren, se recopilaron los datos desde las historias clínicas, se categorizaron en tres niveles de complejidad en rehabilitación y se hizo el análisis estadístico. Resultados: Se estudiaron 34 usuarios, el diagnóstico más recurrente fue el accidente cerebro vascular en el 82,3%. En las escalas funcionales, todos los valores cambiaron de mayor a menor severidad, luego de la rehabilitación (Rankin modificado, índice de Barthel, el nivel funcional y velocidad de marcha). En relación con la recuperación proporcional, los pacientes de baja complejidad lograron un 13,5%, los de mediana el 83% y los de alta un 25%. Conclusiones: Los resultados indican que un programa de Neurorehabilitación motora ambulatorio proporciona cambios funcionales favorables a los pacientes de mediana complejidad en rehabilitación. El uso de una categorización de rehabilitación basada en la complejidad es una opción útil en el entorno clínico, pero se requiere de mayores investigaciones.

Background: There are multiple factors that hinder access to high intensity therapies. Few studies have considered the effectiveness of outpatient motor neurorehabilitation based on direct patient care, caregiver-mediated exercises and self-directed exercises. Objetive: Evaluate the effect of an categorized outpatient motor neurorehabilitation program in a Public Hospital with respect to functionality, mobility and balance. Material and Method: Retrospective cohort study. The patients seen in 2018 at the Neurorehabilitation polyclinic of the Carlos Van Buren Hospital were analyzed, the data was collected from the medical records, they were categorized into three levels of complexity in rehabilitation and the statistical analysis was performed. Results: A total of 34 users were studied, the most recurrent diagnosis was stroke in 82.3%. On the functional scales, all values changed from highest to lowest severity post intervention (modified Rankin, Barthel index, functional level and walking speed). In relation to proportional recovery, low complexity patients achieved 13.5%, median 83% and high 25%. Conclusions: The results indicate that an outpatient motor Neurorehabilitation program provides favorable functional changes for patients of medium complexity in rehabilitation. The use of a complexity-based categorization of rehabilitation is a useful option in the clinical setting, but further research is required.

Research on the Optimization of Traditional Chinese Medicine Governance System from the Perspective of Complexity / 中国医学伦理学

The complexity of the development history, culture and system of Traditional Chinese Medicine (TCM) deeply affect its inheritance, innovation and development. From the perspective of complexity, and based on the framework of "situation-theory-tool", this paper analyzed the complexity and dilemma of TCM governance. The complexity of TCM governance requires continuous adjustment of the governance system. On the one hand, the optimization of the government governance system should clarify the relationship between power and responsibility, and stimulate the endogenous power of local governments. On the other hand, the concept of "collaborative governance" should be used to realize the resource integration and functional synergy of different subjects in the horizontal structure of TCM governance, and enhance the capability of joint action.

Comprehensive comparison between Halcyon 2.0 and Truebeam VMAT plans for different treatment sites: dosimetric quality and plan complexity / 中华放射肿瘤学杂志

Objective:To analyze the differences in dosimetric quality and plan complexity of volumetric modulated arc therapy (VMAT) plans based on Halcyon 2.0 and Truebeam for different treatment sites of the patients.Methods:Halcyon 2.0 VMAT plans in head & neck, chest, abdomen, and pelvis treatment sites of 49 cases were retrospectively selected and the VMAT plans were re-designed based on Truebeam with the same optimization parameters. The differences in dosimetric metrics and plan complexity between the two types of plans were compared and analyzed. P<0.05 was considered as statistically significant. Results:In terms of PTV, Halcyon 2.0 plans showed better homogeneity index (HI), conformal index (CI) in the head & neck and chest. Besides, Halcyon 2.0 plans yielded better D 98% and CI in the abdomen and better D 2% in the pelvis. For organs at risk (OAR), the D 20% and D mean of bilateral lungs, and D meanof heart for Halcyon 2.0 plans in the chest were lower than those for Truebeam plans (all P<0.05). For the complexity metrics, the median average aperture area variability (AAV) of Halcyon 2.0 plans in the head & neck, abdomen and pelvis were 0.414, 0.425 and 0.432, which were better than 0.385, 0.368 and 0.361 of Truebeam plans in the corresponding sites, respectively. In the abdomen and pelvis, Halcyon 2.0 plans showed better median modulation complexity score (MCS) than Truebeam plans (0.320 vs. 0.268, 0.303 vs. 0.282; both P<0.05). The median small aperture score (SAS) for all plans of Halcyon 2.0 were better than that of Truebeam plans (all P<0.05), and the median plan average beam area (PA) of all plans of Halcyon 2.0 were larger than that of Truebeam plans (all P<0.05). Conclusions:Compared with conventional fractionated VMAT plans based on Halcyon 2.0 and Truebeam, Halcyon 2.0 plans have similar or even better dosimetric quality. However, Halcyon 2.0 plans have lower plan complexity, which makes it an advantage in clinical application.

This study combines self-learning with a set of online and offline teaching and learning methods such as lecture teaching, case discussion and experimental method. In addition, this study designs a five-step blended teaching mode as well as a multi-tool and multi-dimensional comprehensive evaluation system of the whole process. Both the blended teaching mode and the comprehensive evaluation system have achieved good results after the implementation. The chapter test results show that the students' test scores applying this kind of blended teaching mode are significantly higher than that applying the traditional teaching mode; the ability test results show that under the high complexity blended teaching mode, the students' ability has been improved more effectively, which is more conducive to the realization of the core competence goals in the professional training objectives and teaching objectives.

Decreasing complexity of glucose time series derived from continuous glucose monitoring is correlated with deteriorating glucose regulation / 医学前沿

Most information used to evaluate diabetic statuses is collected at a special time-point, such as taking fasting plasma glucose test and providing a limited view of individual's health and disease risk. As a new parameter for continuously evaluating personal clinical statuses, the newly developed technique "continuous glucose monitoring" (CGM) can characterize glucose dynamics. By calculating the complexity of glucose time series index (CGI) with refined composite multi-scale entropy analysis of the CGM data, the study showed for the first time that the complexity of glucose time series in subjects decreased gradually from normal glucose tolerance to impaired glucose regulation and then to type 2 diabetes (P for trend < 0.01). Furthermore, CGI was significantly associated with various parameters such as insulin sensitivity/secretion (all P < 0.01), and multiple linear stepwise regression showed that the disposition index, which reflects β-cell function after adjusting for insulin sensitivity, was the only independent factor correlated with CGI (P < 0.01). Our findings indicate that the CGI derived from the CGM data may serve as a novel marker to evaluate glucose homeostasis.

Consultorio de Salud Ambiental en un Hospital Privado de Comunidad de la Ciudad de Buenos Aires / Environmental Health consulting office in a Private Community Hospital of the Buenos Aires City

En los últimos años surge el concepto de Una Sola Salud que reconoce la interdependencia sistémica al observar que los cambios en la salud humana se expresan de manera sincrónica e indivisible de la salud del ambiente. Nuevas enfermedades y daños crónicos inespecíficos ocurren a la par de la pérdida de biodiversidad y vitalidad. En las últimas décadas venimos observando el surgimiento de "adaptaciones sistémicas" que requieren un abordaje desde la clínica y la toxicología a nivel individual y desde la epidemiología de la complejidad a nivel poblacional. Luego de un largo recorrido de investigaciones, el Hospital Italiano formalizó el consultorio de Salud Ambiental con la intención de brindar respuesta a la demanda de pacientes que atribuyen síntomas y signos a la polución ambiental. (AU)

In recent years, the concept of One Health has emerged, recognizing the systemic interdependence and the changes in human health that are expressed synchronously and indivisible from the environment. New diseases and nonspecific chronic damage are occuring in parallel with the loss of biodiversity and vitality.In recent decades we have observed the appearance of "systemic adaptations" that require a clinical and toxicological approach at the individual level, and address the population level from an epidemiological and complexity science paradigm. After many years of research, the Hospital Italiano de Buenos Aires formalized the Environmental Health consulting office and the measurement of glyphosate levels, giving answer to the demand of patients who associate their signs and symptoms to environmental pollution.

Complexity theory in the management of patients with pain

Nonlinear systems are not susceptible to being investigated with reductionist methods. In this sense, complexity theory offers an alternative approach to quantify the importance of contextual factors (CFs) in the patient with pain. The result of the positive (placebo) or negative (nocebo) use of CFs in the therapeutic setting could be responsible for a large part of a non-specific component of the efficacy of the treatment, directly affecting the quality of the results related to the patient's health (for example, pain, disability, or satisfaction). In recent years, understanding of the value of these effects has increased. Despite growing interest, knowledge, and awareness of them is currently limited and heterogeneous among health professionals, reducing their translational value in the field of health.Keywords: complexity, contextual factors, pain, health professionals, placebo, nocebo.

Los sistemas no lineales no son susceptibles de ser investigados con métodos reduccionistas. En este sentido, la teoría de la complejidad ofrece un enfoque alternativo para cuantificar la importancia de los factores contextuales (FCs) en el paciente con dolor. El resultado del uso positivo (placebo) o negativo (nocebo) de FCs en el tratamiento podría ser responsable de gran parte de un componente no específico de la eficacia del tratamiento, afectando directamente la calidad de los resultados relacionados con la salud del paciente (por ejemplo, dolor, funcionalidad o satisfacción).En los últimos años se ha incrementado la comprensión del valor de estos efectos. A pesar del creciente interés, el conocimiento y la conciencia de ellos es actualmente limitado y heterogéneo entre profesionales de la salud, lo que reduce su valor traslacional en el campo de la salud.Palabras clave: complejidad; factores contextuales; profesionales de la salud; dolor; placebo; nocebo.

Complexity score-based plan quality control of VMAT / 中华放射肿瘤学杂志

Objective:To explore the difference in the complexity of different treatment planning systems, multi-leaf collimator (MLC) types and treatment sites of volume-modulated arc therapy (VMAT), and propose a complexity score for plan quality control.Methods:Statistical analysis of 12 complexity metrics including Monaco and Eclipse, Agility, Millennium and High-definition MLC, nasopharyngeal, lung and cervical cancer was performed. Spearman correlation coefficient between complexity metrics was calculated. Principal component analysis was conducted to reduce the dimensionality of the original data set to the first two principal components and explain its physical meaning. Complexity score based on the principal components was calculated to establish warning and action thresholds for plan quality control. The correlation between complexity metrics and γ pass rate was analyzed.Results:Except cervical cancer aperture sub-regions metric, other metrics had significant differences between Monaco and Eclipse. Monaco MLC had a more regular field but higher MU, smaller leaf gap, and longer leaf travel distance. High-definition MLC with smaller leaf width significantly added MLC aperture-related metrics. The first two principal components explained over 80% of the total variance of the original dataset, complexity score was weighted average of first two principal components. The distribution of complexity score for different equipment and sites was different. The warning threshold was expressed as the average plus standard deviation, and the action threshold was expressed as the average plus 2 standard deviations. Complexity metrics and complexity scores had small correlation with γ pass rate, showing weak or irrelevant but statistically significant. Conclusions:Different planning systems, MLC types, and treatment site complexity metrics are significantly different. The complexity score is a useful tool for plan quality control.

ObjectiveTo investigate the effect and mechanism of Wumeiwan against Lewis lung cancer in mice with syndrome of cold and heat in complexity based on hepatocyte growth factor/mesenchymal-epithelial transition factor （HGF/C-Met） signaling pathway. MethodTwenty healthy male mice were classified into blank group， model group （equivalent volume of distilled water， ig）， cisplatin group （4.0 mg·kg-1 cisplatin， ip）， and Wumeiwan group （12.5 mL·kg-1 Wumeiwan， ig）， with 5 in each group. Lewis lung cancer with the syndrome of cold and heat in complexity was induced in mice except the blank group by gavage of propylthiouracil， Zhimu Shigaotang， and Fanxieye， ice-water swimming， and subcutaneous injection of dry yeast suspension and Lewis cell suspension under the right armpit. After modeling， administration began and lasted 6 weeks. After the experiment， the tumor weight， tumor volume， tumor inhibition rate， and lung cancer metastasis-inhibiting proportion were measured and calculated. The pathological morphology of lung tissue was observed based on hematoxylin and eosin （HE） staining. The growth state of tumor tissue was analyzed by immunohistochemistry. The mRNA expression of HGF and C-Met was detected by Real-time polymerase chain reaction （PCR）， and the protein expressions of HGF， C-Met， survivin， and X-linked inhibitor of apoptosis protein （XIAP） by Western blot. ResultCompared with the blank group， the model group showed high mRNA expression of HGF and C-Met and protein expression of HGF， C-Met， surviving， and XIAP （P<0.01）. Compared with the model group， Wumeiwan group displayed low proportion of positive cells， positive cell density， positive score （P<0.05）， histochemical score， tumor weight， tumor volume （P<0.01）， mRNA expression of HGF and C-Met （P<0.01）， and protein expression of HGF， C-Met， surviving， and XIAP （P<0.01）. Compared with the model group， the cisplatin group displayed decrease in the proportion of positive cells， density of positive cells （P<0.05）， positive score， tumor weight， tumor volume （P<0.01）， mRNA expression of HGF and C-Met （P<0.01）， and protein expression of HGF， C-Met， surviving， and XIAP （P<0.01）， and insignificant variation in the histochemical score. Wumeiwan group had high mRNA expression of HGF （P<0.01）， and insignificant variation in the proportion of positive cells， positive cell density， histochemical score， positive score， tumor weight， tumor volume， mRNA expression of C-Met， and protein expression of HGF， C-Met， surviving， and XIAP. ConclusionWumeiwan can slow down the progression of Lewis lung cancer in mice with syndrome of cold and heat I complexicity by inhibiting HGF/C-Met signaling pathway.

Trata-se de um estudo teórico com o objetivo de aproximar aportes sobre o idadismo ao tetragrama dialógico de interações, proposto por Morin, no contexto do trabalho na Estratégia Saúde da Família e na Atenção Primária à Saúde. Para isso, foi realizada uma projeção simbólica de saberes sobre o etarismo organizada em quatro atos: ordem, dispersão, interação e religação. Conclui-se que esse exercício teórico pode ser transmutado para o cotidiano de trabalho na Saúde, no qual a compreensão da existência do tetragrama dialógico, atuando simultaneamente na vida de forma antagônica, concorrente e complementar, pode incitar um pensar crítico, criativo e complexo em prol de saberes e de práticas frente à complexidade do idadismo.(AU)

Se trata de un estudio teórico con el objetivo de aproximar contribuciones sobre el edadismo al tetragrama dialógico de interacciones, propuesto por Morin, en el contexto del trabajo en la Estrategia Salud de la Familia y de la Atención Primaria de la Salud. Para ello, se realizó una proyección simbólica de saberes sobre el edadismo organizada en cuatro actos: orden, dispersión, interacción y reconexión. Se concluyó que este ejercicio teórico pueda transmutarse para el cotidiano de trabajo en la salud, en donde la comprensión de la existencia del tetragrama dialógico, actuando simultáneamente en la vida de forma antagónica, competidora y complementaria, pueda incitar un pensar crítico, creativo y complejo en pro de saberes y de prácticas ante la complejidad del edadismo.(AU)

This is a theoretical study that aims to articulate contributions on ageism with the dialogic tetragrammaton of interactions, proposed by Morin, in the context of work in the Family Health Strategy and Primary Health Care. To accomplish this, a symbolic projection of knowledge about ageism was carried out, organized in four acts: order, dispersion, interaction, and reconnection. We concluded that this theoretical exercise can be transmuted to the daily work in health care, and that understanding the existence of the dialogic tetragrammaton, which acts in life simultaneously in antagonistic, concurrent and complementary ways, can stimulate critical, creative and complex thinking in favor of knowledge and practices that take the complexity of ageism into account.(AU)

Development of the modified medication regimen complexity index of Chinese version(mMRCI-C)and its validation in elderly diabetic patients / 中华全科医师杂志

Objective:To develop the modified medication regimen complexity index of Chinese version (mMRCI-C)and test its reliability and validity.Method:The Chinese version of MRCI was developed by modification,translation and back translation. The MRCI was interculturally adapted by 2-rounds of expert consultation and pilot study to ensure the semantics, content and conceptual equivalence. The validation of the mMRCI-C scale was tested among 420 community-dwelling elderly patients with type 2 diabetes mellitus(T2DM) in Shanghai Changfeng Community Health Service Center from October to December 2020. SPSS 23.0 was used to analyze the reliability and validity of the scale.Results:The mMRCI-C scale included 3 dimensions, namely drug dosage form (14 entries), medication frequency (5 entries), and additional instructions (6 entries), with a total of 25 entries. Among 420 valid questionnaires collected,the respondents were 212 males (50.4%) and 208 females (49.6%) with a mean age of (71.4±8.1) years. The test-retest reliability was 0.999 and internal consistency reliability was 0.849. The content validity exceeded 0.80,the convergent validity was 0.932; and discriminant validity P<0.001. Conclusion:The preliminary testing results show that the reliability and validity of the mMRCI-C scale are satisfactory.

Resumen El estudio científico del corazón nos ha permitido conocer su estructura y función profundamente, mediante la fragmentación y el análisis de sus partes, atendiendo a las pautas del método que tantos logros nos ha dado. Sin embargo, al momento de volver a ensamblar esos fragmentos analizados nos percatamos de que algo falta; simplemente la suma de las partes no hace al todo. Es así que, desde hace décadas, numerosos científicos han estudiado estrategias novedosas que permitan entender los fenómenos naturales desde modelos más incluyentes, abiertos e integradores, que atiendan con cercanía a las interacciones más que a los componentes. De esta manera, observamos que muchas variables suelen transgredir el plano convencional y parten hacia la no linealidad y la fractalidad, formando un tejido complejo que mantendrá su estructura mientras termodinámicamente sea viable. Así, en este documento se muestra la manera en que el estudio no lineal de la dinámica compleja cardiovascular comienza a darnos luz en muchas de las preguntas que a diario se plantea el cardiólogo clínico.

Abstract The science-based study of the heart has allowed us to know its structure and function deeply, through the fragmentation and analysis of its parts, following the guidelines that so many achievements have given to us. However, at the time of reassembling those analyzed fragments, we realize that something is missing; the simply sum of the parts is not equal to everything. Thus, for decades, numerous scientists have studied novel strategies that allow us understanding, every natural phenomena from a more inclusive, open and integrative models, which closely address to interactions rather than components. In this way, we can observe how, the behavior of many variables usually transgress the conventional plane and moves towards non-linearity and fractality, making a complex tissue that will maintain its structure while thermodynamically viable. Thus, this document shows the way how, the non-linear study of complex cardiovascular dynamics, begins to give us answers to many questions that the clinical cardiologist poses every day.
