La selección de atletas élite desde edad temprana: reflexión desde la perspectiva de los sistemas complejos / A seleção de atletas de elite desde cedo: reflexão a partir da perspectiva de sistemas complexos / The selection of elite athletes from an early age: reflection from the perspective of complex systems

RESUMEN Introducción: En este estudio, se examinó la idoneidad de seleccionar atletas élite desde una edad temprana. Objetivo: El objetivo de este estudio consistió en verificar si el comportamiento identificado en investigaciones antecedentes también ocurre entre los mejores atletas mundiales de todos los tiempos que compiten en la carrera de 100 metros. Materiales y métodos: Para ello, y con base en un análisis de las clasificaciones oficiales de todos los tiempos masculinos y femeninos de la Asociación Internacional de Federaciones de atletismo en la referida prueba, se utilizó muestras en categoría absoluta (Top-1,000 hasta el 31/12/2018) y categoría sub-20 (Top-100 hasta el 31/12/2003); se aplicaron leyes de potencia y otras estrategias típicas de los sistemas complejos para analizar los datos. Resultados: los resultados muestran cómo, con demasiada frecuencia, los mejores corredores masculinos y femeninos del mundo en la categoría sub-20 no evolucionan positivamente durante el resto de su carrera deportiva mejorando sus registros en las categorías superiores. Solo 51 hombres de los 100 mejores corredores sub-20 de todos los tiempos, lograron mejorar sus registros una vez que alcanzaron la categoría sénior, y las mejoras no presentaron siempre progresiones estadísticamente significativas. En consecuencia, una inversión excesiva en recursos humanos y materiales para identificar individuos con altas capacidades atléticas, no es siempre la mejor estrategia. Conclusiones: el deporte de nivel a edades tempranas puede ser un error metodológico que debe evitarse a la hora de construir las reservas deportivas de un país o federación deportiva.

RESUMO Introdução: Neste estudo, examinou-se a adequação da seleção de atletas de elite desde tenra idade. Objetivo: O objetivo deste estudo foi verificar se o comportamento identificado em pesquisas anteriores também ocorre entre os melhores atletas do mundo de todos os tempos que competem na prova de 100 metros. Materiais e métodos: Para isso, e com base na análise das classificações oficiais de todos os tempos para homens e mulheres da Associação Internacional de Federações de Atletismo na prova supracitada, foram utilizadas amostras em categoria absoluta (Top-1.000 até 31/12 /2018) e sub-20 (Top-100 até 31/12/2003); Leis de potência e outras estratégias típicas de sistemas complexos foram aplicadas para analisar os dados. Resultados: Os resultados mostram como, muitas vezes, os melhores corredores masculinos e femininos do mundo na categoria sub-20 não evoluem positivamente durante o resto de sua carreira esportiva, melhorando seus registros nas categorias superiores. Apenas 51 homens dos 100 melhores corredores sub-20 de todos os tempos conseguiram melhorar seus tempos quando chegaram à categoria sênior, e as melhorias nem sempre mostraram progressões estatisticamente significativas. Consequentemente, um investimento excessivo em recursos humanos e materiais para identificar indivíduos com altas habilidades atléticas nem sempre é a melhor estratégia. Conclusões: o esporte de nível em idade precoce pode ser um erro metodológico que deve ser evitado na construção das reservas esportivas de um país ou federação esportiva.

ABSTRACT Introduction: In this study, the suitability of selecting elite athletes from an early age was examined. Objective: The objective of this study was to verify if the behavior identified in previous research also occurs among the world's best athletes of all time who compete in the 100-meter race. Materials and methods: For this, and based on an analysis of the official classifications of all times for men and women of the International Association of Athletics Federations in the referred test, samples were used in absolute category (Top-1,000 up to the 12/31/2018) and sub -20 category (Top - 100 until 12/31/2003); power laws and other strategies typical of complex systems will be applied to analyze the data. Results: The results show how, all too often, the best male and female runners in the world in the under-20 category do not evolve positively during the rest of their sports career. improving their records in the higher categories. Only 51 men out of the top 100 U-20 runners of all time managed to improve their times once they reached the senior category, and the improvements did not always show statistically significant progressions. Consequently, an excessive investment in human and material resources to identify individuals with high athletic abilities is not always the best strategy. Conclusions: level sport at an early age can be a methodological error that should be avoided when building the sports reserves of a country or sports federation.

Avances de un estudio psicoanalítico acerca de la distancia afectiva en la relación madre-bebé / Advances of a psychoanalytic study about the affective distance in the mother-baby relationship

Medir el empuje que transmite la voz materna es casi inconcebible, (Didier-Weill,1998) ya que la estructura de su discurso primordial incluye una paradoja. ¿De qué manera entonces medir un espacio de encuentro que está en construcción? Este estudio explora la distancia afectiva en la díada madre-bebé desde una perspectiva intersubjetiva, durante la emisión del fenómeno sonoro denominado "tono maternés". Como parte de los avances de la investigación en curso, se destaca el valor de la interdisciplina para la obtención de los datos y el modo en que su procesamiento conduce a una posible categorización de su objeto de estudio. La consulta a expertos (del campo de la fonoaudiología y la psicomotricidad) permitió abordar un "único cuerpo suficientemente complejo"(Bernardi,2000)y de este modo cercar la realidad compartida. Se acuerda con Winnicott (1989) en la idea de que, si distintos observadores llegan a conclusiones semejantes, probablemente signifique que se ocupan de cosas reales(AU)

Measuring the drive transmitted by the maternal voice is almost inconceivable (Didier-Weill 1998). This statement is based on the idea that the primordial discourse structure is paradoxical. How then, to measure a meeting space that is under construction. One of the objectives of this psychoanalytic thesisis to explore the affective distance present in the dyad, while she emits the sound phenomenon 'babytalk'. As part of the progress, the author presents some moments of the investigation. This paper highlights the value of interdisciplinary approach to obtain the data and presents a possible categorization of the affective distance present in the early relationship.To study the real movements for the psychical constitution, it was required the dialogue with experts (from the areas of phonology and psychomotricity) to border a shared reality and address a "single sufficiently complex body (Bernardi, 2000). In agreement with Winnicott (1989), if different observers arrive at a similar conclusion, it possibly implies that they are dealing with real things(AU)

Differential associations between body mass index and outcome in different age groups in patients with myocardial infarction

Objective: To investigate the association between age and body mass index (BMI) and mortality in patients with myocardial infarction (MI). Methods We divided 6453 patients into three age groups (<60, 60 e75, >75 years) and five BMI categories. Thirty-day and long-term all-cause mortality were assessed. Results: No association was found between the BMI category and 30-day mortality in any age group. The association between BMI and long-term multivariable-adjusted mortality risk was age-dependent. Overweight patients had a lower risk than patients with BMI <25 kg/m2 in all age groups (HR 0.62; 95%CI 0.45e0.85; p ¼ 0.003, HR 0.78; 95%CI 0.65e0.93; p ¼ 0.005, HR 0.82; 95%CI 0.70e0.95; p ¼ 0.011 for ages <60, 60e75, >75 years, respectively). The lower risk of death as a function of BMI shifted upward with age, and the risk was also lower in patients with obesity grade I (HR 0.81; 95% CI 0.66e0.98; p ¼ 0.035 and HR 0.78; 95% CI 0.63e0.97; p ¼ 0.023 for ages 60e75, >75 years, respectively). Excessive obesity was harmful only in the oldest group. Patients with obesity grade III had more than a 2.5 times higher mortality risk than patients with BMI <25 kg/m2 only in this group (HR 2.58; 95%CI 1.27e5.24; p ¼ 0.009). An obesity paradox was found in all age groups. Conclusion: Our results suggest that moderate weight gain with age improves long-term survival after MI and that the magnitude of this “protective” weight gain is greater in older compared to younger patients. However, excessive weight gain (obesity grade III) is particularly harmful in the oldest age group. The exact relationship between BMI, age, and mortality remains unclear.

Obesity in cases undergoing the surgical procedure of lung lobectomy: risk or benefit?

SUMMARY OBJECTIVE: The aim of the study was to evaluate the effect of body mass index on patients' short-term results following lung lobectomy. METHODS: In this retrospective study, we compared the perioperative and short-term postoperative results of obese (BMI≥30 kg/m2) versus non-obese patients (BMI<30 kg/m2) who underwent anatomical lung resection for cancer. The two groups had the same distribution of input risk factors and the same ratio of surgical approaches (thoracoscopy vs. thoracotomy). RESULTS: The study included a total of 144 patients: 48 obese and 96 non-obese patients. Both groups had the same ratio of thoracoscopic vs. thoracotomy approach (50/50%), and were comparable in terms of demographics and clinical data. The g roups did not significantly differ in the frequency of perioperative or postoperative complications. Postoperative morbidity was higher among non-obese patients (34.4 vs. 27.1%), but this difference was not statistically significant (p=0.053). Hospital stay was similar in both study groups (p=0.100). Surgery time was significantly longer among obese patients (p=0.133). Postoperative mortality was comparable between the study groups (p=0.167). CONCLUSIONS: Obesity does not increase the frequency of perioperative and postoperative complications in patients after lung lobectomy. The slightly better results in obese patients suggest that obesity may have some protective role.

Paradoxos na divulgação de salários de servidores em municípios / Paradojas en la difusión de información sobre los sueldos de los funcionarios por los municipios / Paradoxes on the disclosure of civil servants' salary information by local governments

Resumo A folha de pagamento é uma das maiores despesas do município, porém uma das mais difíceis de serem monitoradas. Se a divulgação dos salários de servidores é de interesse público para controle, a divulgação das despesas com pessoal, na forma como previsto em lei, pode não ser suficiente para detectar diversos tipos de irregularidades. Analisamos os paradoxos envolvidos na divulgação de dados da folha de pagamento e as tensões que emergem do posicionamento de diversos interessados na questão. Entrevistamos profissionais de prefeituras, sindicatos, empresas de softwares, tribunais de contas, organizações sociais e jornalistas. Procuramos reunir diversas perspectivas e interesses envolvidos na divulgação de salários e benefícios de servidores como exemplo dos desafios de ampliar a transparência pública. Com abordagem indutiva, apresentamos uma lista não exaustiva de irregularidades que reconhecidamente ocorrem no país e que, por não serem detectadas apenas com os dados divulgados nos portais de transparência, demandam cooperação entre diversos atores de controle.

Resumen La nómina es uno de los mayores gastos del municipio, pero también es uno de los más difíciles de monitorear. Si la divulgación de los salarios de los funcionarios públicos es de interés público para su control, la divulgación de los gastos en personal según lo dispuesto por la ley puede no ser suficiente para identificar algunas irregularidades. Analizamos las paradojas presentes en la apertura de dichos datos y las tensiones que surgen del posicionamiento de los diferentes interesados en el asunto. Entrevistamos a profesionales de alcaldías, sindicatos, empresas de software, tribunales de cuentas, organizaciones sociales y periodistas para reunir diversas perspectivas e intereses involucrados en la divulgación de sueldos y beneficios de los servidores públicos como ejemplo de los desafíos para ampliar la transparencia pública. Con un enfoque inductivo, presentamos una lista no exhaustiva de las irregularidades que a menudo ocurren en Brasil que, por no ser detectadas simplemente a través de los datos publicados en los portales de transparencia, exigen la cooperación entre los diferentes agentes de control para combinar múltiples fuentes de datos y evidencias.

Abstract: Although local governments' payrolls are a significant expense, they are one of the most difficult to monitor. The disclosure of civil servants' salaries to improve control is a measure of public interest, but the mere information on the government's personnel expenses as provided by law may not be sufficient to detect irregularities. This study analyzes the paradoxes of disclosing salary information and the tensions among the parties related to this issue. We interviewed local government employees, unions, software companies, courts of accounts, nonprofit organizations, and journalists, gathering different interests and perspectives, addressing the issue as an example of the challenges to improve public transparency. Based on an inductive approach, the research offers a non-exhaustive list of irregularities in Brazil that are not detected by simply disclosing information in transparency portals. Our findings point out that detecting and addressing such irregularities require the cooperation of several control agents to combine multiple data sources and evidence.

Ilusão, criatividade e paradoxo: pré-condições para a capacidade de brincar / Ilusión, creatividad y paradoja: condiciones previas para la capacidad de jugar / Illusion, creativity and paradox: preconditions for the ability to play / Illusion, créativité et paradoxe: conditions préalables à la capacité de jouer

Inscrevendo-se de maneira singular na tradição psicanalítica, Winnicott estabelece uma situação de observação padronizada de bebês em que o brincar surge como critério diagnóstico e terapêutico para o desenvolvimento infantil. Esta observação passa a operar como uma matriz do pensamento winnicottiano, a partir da qual será elaborada a teoria do desenvolvimento emocional primitivo. O presente artigo busca destacar quais seriam as precondições para o desenvolvimento da capacidade de brincar do bebê humano, identificando alguns pontos de continuidade e inflexão com relação à teorização freudo-kleiniana sobre o brincar e o desenvolvimento emocional da criança: as relações entre a critividade, ilusão e o paradoxo

Suscribiéndose de una manera única a la tradición psicoanalítica, Winnicott establece una situación de observación estandarizada de bebés en la que el juego aparece como un criterio diagnóstico y terapéutico para el desarrollo infantil. Esta observación comienza a funcionar como una matriz del pensamiento winnicotiano a partir del cual se elaborará la teoría del desarrollo emocional primitivo. El presente artículo busca resaltar cuáles son las condiciones previas para el desarrollo de la capacidad de juego del bebé humano, identificando algunos puntos de continuidad e inflexión en relación con la teorización freudo-kleiniana sobre el juego del niño y el desarrollo emocional: las relaciones entre la crítica, ilusión y la paradoja

Subscribing in a unique way to the psychoanalytic tradition, Winnicott establishes a situation of standardized observation of babies in which playing appears as a diagnostic and therapeutic criterion for child development. This observation starts to operate as a matrix of Winnicottian thought from which the theory of primitive emotional development will be elaborated. The present article seeks to highlight which are the preconditions for the development of the human baby's ability to play, identifying some points of continuity and inflection in relation to Freudo-Kleinian theorizing about the child's play and emotional development: the relationships between criticism , illusion and the paradox

S'inscrivant de façon unique à la tradition psychanalytique, Winnicott établit une situation d'observation standardisée des bébés dans laquelle le jeu apparaît comme un critère diagnostique et thérapeutique du développement de l'enfant. Cette observation commence à fonctionner comme une matrice de la pensée winnicottienne, à partir de laquelle la théorie du développement émotionnel primitif sera élaborée. Cet article cherche à mettre en évidence quelles sont les conditions préalables au développement de la capacité de jeu du bébé humain, en identifiant quelques points de continuité et d'inflexion en relation avec la théorisation freudo-kleinienne du jeu et du développement émotionnel de l'enfant: les relations entre critique, illusion et paradoxe.

Interações sexuais entre indivíduos do mesmo sexo: um olhar evolucionista / Same-sex sexual interactions: an evolutionary perspective / Interactions sexuelles entre personnes du même sexe: une perspective évolutionniste / Interacciones sexuales entre individuos del mismo sexo: una visión evolucionista

Resumo Sob uma perspectiva evolutiva, as interações sexuais entre indivíduos do mesmo sexo foram por muito tempo consideradas um grande paradoxo. Isso por terem persistido no decorrer das gerações apesar de supostamente não oferecerem benefícios reprodutivos diretos, reduzindo, aparentemente, a aptidão individual. Apesar disso, são comuns em muitas espécies animais. Neste artigo, revisaremos algumas das hipóteses funcionais que tentam resolver esse quebra-cabeça evolutivo. Algumas dessas hipóteses consideram essas interações adaptativas, o que significa que trariam benefícios para os indivíduos. Outras as consideram neutras, derivadas de características realmente vantajosas. Por fim, existem as que consideram essas interações como não-adaptativas e potencialmente prejudiciais aos indivíduos. Ao final, abordaremos uma hipótese revolucionária que, de forma inédita, questiona se as interações sexuais envolvendo exclusivamente indivíduos de sexos diferentes seriam realmente o estado basal do comportamento sexual.

Abstract From an evolutionary point of view, same-sex sexual interactions have long been considered a major paradox. This is because they have persisted throughout generations despite, presumably, not offering direct reproductive benefits and, apparently, reducing individual fitness. Nonetheless, same-sex sexual interactions are common in many animal species. This paper reviews some functional hypotheses that seek to solve this evolutionary puzzle: some consider it adaptative, meaning that these behaviors would bring benefits to individuals; others see it as a neutral by-product of other advantageous characteristics. A third branch understand same-sex sexual interactions to be non-adaptative and potentially deleterious to individuals. Finally, this paper discusses a revolutionary hypothesis that, unprecedently, questions whether sexual interactions involving exclusively individuals of the opposite sex are in fact the basal state of sexual behavior.

Résumé Du point de vue de l'évolution, les interactions sexuelles entre personnes du même sexe ont longtemps été considérées comme un grand paradoxe majeur. En effet, elles ont persisté au fil des générations bien qu'elles n'offrent vraisemblablement pas d'avantages reproductifs directs et qu'elles réduisent apparemment la valeur adaptative individuelle. Néanmoins, sont courantes chez de nombreuses espèces animales. Cet article passe en revue certaines hypothèses fonctionnelles qui cherchent à résoudre cette énigme évolutive : certaines considèrent les interactions comme adaptatives, ce qui signifie que ces comportements apporteraient des avantages aux individus ; d'autres voient les comme un sous-produit neutre d'autres caractéristiques avantageuses. Une troisième branche les comprend comme étant non-adaptatives et potentiellement délétères pour les individus. Enfin, on discute d'une hypothèse révolutionnaire qui, sans précédent, remet en question le fait que les interactions sexuelles impliquant exclusivement des individus du sexe opposé serait l'état ancestral du comportement sexuel.

Resumen Desde una perspectiva evolutiva, las interacciones sexuales entre individuos del mismo sexo han sido consideradas por mucho tiempo como una enorme paradoja. Esto es debido a que han persistido generación tras generación a pesar de, supuestamente, no ofrecer beneficios reproductivos directos, reduciendo, aparentemente, la aptitud individual. Sin embargo, son comunes en muchas especies de animales. En este artículo repasaremos algunas de las hipótesis funcionales que intentan resolver este rompecabezas evolutivo. Algunas de estas hipótesis consideran que estas interacciones son adaptativas, lo que trae benefícios a los individuos. Otras hipótesis las consideran neutras, derivadas de características realmente ventajosas. Mientras que otras consideran estas interacciones como no adaptativas y potencialmente perjudiciales para los individuos. Por último, expondremos una hipótesis revolucionaria que, de manera inédita, cuestiona si las interacciones sexuales que involucran exclusivamente a individuos de diferentes sexos son realmente el estado basal del comportamiento sexual.

Medida socioeducativa, ambiente escolar e alojamento psíquico / Socio-educational measure school environment and psychic lodging / Medida socioeducativa, entorno escolar y alojamento psíquico

Este artigo discorre sobre adolescentes que foram alfabetizados em prazos bastante curtos, quando internados para cumprimento de medida socioeducativa, após terem fracassado recorrentemente no curso regular de escolarização. A investigação buscou compreender os sentidos do êxito tardio em ambiente de privação de liberdade. Participaram do estudo 15 adolescentes de quatro unidades da Fundação CASA, que não possuíam competência de leitura e escrita quando de sua internação. Para tanto, os adolescentes foram entrevistados; alguns produziram desenhos, que foram examinados. O trabalho amparou-se na psicanálise, centralmente em Donald W. Winnicott. Conclui-se que há necessidade de o ambiente educativo se apresentar como espaço continente para as dificuldades e para processos identificatórios, podendo apresentar-se como um "alojamento" em que o "paradoxo limite e espaço" e as ressignificações ganham o sentido de amparo psíquico que, dentre outras coisas, interfere na aprendizagem e pode ou não chegar a ser curativo (Au).

This article discusses adolescents who were taught to read and write within a very short time when interned in compliance with a socio-educational measure, after recurrent failures on regular school courses. The investigation seeks to understand the meanings of late success in an environment of freedom deprivation. 15 adolescents from four Fundação Casa units participated, who were unable to read and write on their internment. To this end, the adolescents were interviewed and some produced drawings, which were examined. The work was supported by psychoanalysis, especially Donald W. Winnicott. It was concluded that there is a need for the educational environment to present itself as a containing space for difficulties and for identificatory processes, able to show itself as "lodging" where the "limit and space paradox" and resignifications gain the meaning of psychic support which, among other things, affects learning and may or may not be ultimately curative (AU).

Este artículo discurre sobre los adolescentes que han sido alfabetizados en plazos bastante cortos cuando fueron internados para el cumplimiento de una medida socioeducativa, después de que hubiesen fracasado recurrentemente en el recorrido normal de la escolarización. La investigación trató de comprender los sentidos del éxito tardío en un entorno de privación de la libertad. Participaron del estudio quince adolescentes de cuatro unidades de la Fundação CASA ("Fundación CASA"), los cuales no poseían competencia de lectura y escritura cuando fueron internados. Para ello, se entrevistaron a los adolescentes; algunos produjeron dibujos, los cuales fueron examinados. El trabajo se amparó en el psicoanálisis, sobre todo en Donald W. Winnicott. Se concluyó que hay la necesidad de que el entorno educativo se presente como un espacio continente para las dificultades y para los procesos identificatorios, apareciendo como un "alojamiento" en que la "paradoja límite y espacio" y las resignificaciones ganan el sentido de auxilio psíquico. Eso, entre otras cosas, interfiere en el aprendizaje y puede o no llegar a ser curativo (AU).

La paradoja de la obesidad en la insuficiencia cardíaca en ancianos / The Obesity Paradox of Heart Failure in the Elderly

RESUMEN Introducción: Múltiples estudios demostraron una relación "protectora" del índice de masa corporal (IMC) incrementado por sobre el IMC normal o bajo en el desarrollo y el pronóstico de la insuficiencia cardíaca. Las categorías de IMC de la población adulta no son adecuadas en la población anciana. Nos proponemos comparar la incidencia de mortalidad global y de reinternación por insuficiencia cardíaca durante el primer año según la categoría de IMC en esta población. Materiales y métodos: Estudio observacional y analítico de una cohorte retrospectiva de pacientes mayores de 65 años internados en la unidad de cuidados intensivos cardiológicos del Hospital Italiano de Buenos Aires (HIBA) con diagnóstico de síndrome de insuficiencia cardíaca aguda (SICA) entre enero de 2013 y diciembre de 2017. Resultados: Se incluyeron 409 pacientes. Los subgrupos con mayor IMC presentaron menor mortalidad al año (peso insuficiente: 53%, normopeso: 41%, sobrepeso: 33%, obesos: 27%, p = 0,008). En el análisis multivariado, el HR para mortalidad anual ajustado por edad, sexo, reinternaciones, insuficiencia renal y tipo de insuficiencia cardíaca fue de 0,51 (IC95% 0,29-0,90) en los pacientes con sobrepeso y de 0,36 (IC95% 0,19-0,67) en los pacientes obesos con respecto a los de peso insuficiente. No hubo diferencias en la mortalidad intrahospitalaria ni en las reinternaciones al año entre los diferentes subgrupos de IMC. Conclusión: En la población de ancianos con SICA, los subgrupos con mayor IMC tienen mejor pronóstico durante el primer año, por lo que se cumple la "paradoja de la obesidad".

ABSTRACT Background: Multiple studies have demonstrated a "protective" relationship of increased body mass index (BMI) over normal or low BMI in the development and prognosis of heart failure. The BMI categories of the adult population are not adequate in the elderly population. We propose to compare the incidence of global mortality and/or readmission for heart failure during the first year according to the BMI category in this population. Methods: This was an observational and analytical study of a retrospective cohort of patients ≥65 years admitted to the cardiology intensive care unit of Hospital Italiano de Buenos Aires with a diagnosis of Acute Heart Failure Syndrome (AHFS) between January 2013 and December 2017. Results: The study included 409 patients. The subgroups with higher BMI had lower mortality at one year (Underweight: 53%, Normal weight: 41%, Overweight: 33%, Obese: 27%, p = 0.008). In the multivariate analysis, annual mortality HR adjusted for age, gender, readmissions, kidney failure and type of heart failure was 0.51 (95% CI 0.29-0.90) for overweight patients and 0.36 (95% CI 0.19-0.67) for patients with obesity compared with underweight patients. There were no differences in inhospital mortality or in readmissions at one year between the different BMI subgroups. Conclusion: In the elderly population with AHFS, the subgroups with higher BMI have a better prognosis during the first year, fulfilling the "obesity paradox".

Obesidad como factor de riesgo para infección por COVID-19: obesidad y COVID-19 / Obesity as a risk factor for COVID-19 infection

La obesidad es una enfermedad que se ha visto relacionada con la pandemia del nuevo coronavirus, sugiriendo que los obesos tienen mayor riesgo a padecer COVID-19 grave y sus complicaciones, cobrando mayor relevancia en Chile, país con tasas elevadas de obesidad. Se revisan mecanismos fisiopatológicos involucrados, efecto de las comorbilidades, posibilidad de atención médica y resultados de una eventual vacunación, corroborando un peor pronóstico para este grupo de pacientes. Se destaca la necesidad de datos antropométricos específicos, además del índice de masa corporal (IMC) para establecer una relación más relevante. La paradoja de la obesidad, de igual manera, carece de evidencias para asociarse al COVID-19.

Obesity is a disease that has been related to the new coronavirus pandemic, suggesting that obese people have a greater risk of suffering from severe COVID-19 and its complications, becoming more relevant in Chile, a country with high rates of obesity. The pathophysiological mechanisms involved, effect of comorbidities, medical care atention and potential vaccination, outcomes are reviewed, showing a worse prognosis for this group of patients. The need for specific anthropometric data is highlighted, in addition to the body mass index (BMI) to establish a more relevant relationship. Likewise, the obesity paradox, lacks of evidence to be associated with COVID-19.

The contradictions in the existing physics and the psychological factors that influence them to be valued

Besides the limitation of cognition level, the factors that affect the correctness of academic evaluation are as follows: collusion-recognizationeffect, backfire effect, cognitive maladjustment, inattentional blindness and aesthetic fatigue. It's hard for readers (especially the reviewers of academic achievements) not to fall into the trap. Therefore, the probability of misjudgment of academic achievements of "questioning and denying current prevailing theories or creating new theories" is very high. The intolerable contradictions in the existing physical theories, such as space paradox, time paradox, quantum entanglement paradox, are exposed by means of thought experiments and "topresentthefacts,reasonthingsout", and take these works as examples to reveal the formation and utilization of these adverse psychological effects. The conclusions are as follows: both special relativity and Copenhagen interpretation of quantum mechanics have fatal injury; it is difficult to eliminate the misjudgment of academic achievements, but the misjudgment rate can be reduced. The concepts of “invariance of spatial attribution”and “inaction association”are established. These works can urge readers to treat new and old physics theories more carefully, promote the development of physics, and promote the birth and improvement of the evaluation theory of science and technology

Evaluation of effect of smoking on myocardial injury and prognosis in patients with acute ST-segment elevation myocardial infarction / 上海交通大学学报（医学版）

Objective • To investigate the influence of smoking on acute myocardial injury and long-term prognosis in the patients with ST-segment elevation myocardial infraction (STEMI) by cardiac magnetic resonance (CMR). Methods • Three hundred and forty-nine STEMI patients were retrospectively selected from a prospective cohort from May 2012 to August 2017, and were followed up for at least 2 years. The primary endpoint was a composite of all-cause death, reinfarction and stroke. The secondary endpoint was heart failure rehospitalization. The patients were divided into smoker group and non-smoker group according to the baseline status of smoking which was recorded at admission. The difference in the incidence of endpoint events was further analyzed in combination with the presence or absence of intramyocardial hemorrhage (IMH) between the two groups. Results • There were 221 patients in the smoker group, accounting for 63.3% of the total sample. The average age of onset in smokers were 4.66 years earlier than nonsmokers. However, smokers showed a lower incidence of left ventricular thrombosis and lower levels of brain natriuretic peptide than non-smokers (P=0.023, P=0.000). There was no difference in the left ventricular ejection fraction between the two groups (P>0.05), but the smokers had a better endsystolic and end-diastolic volume index (P=0.019, P=0.007). Smokers and non-smokers had similar clinical outcomes of all-cause death, reinfarction and stroke (P>0.05). The incidence of heart failure rehospitalization in smokers was quite lower than that of the non-smokers, but this kind of protective effect disappeared after differences in baseline being adjusted (P=0.167). In the patients with IMH, smoking had a protective effect on primary endpoints (HR=0.266, P=0.008), but in the patients without IMH, smokers had a worse outcome of all-cause death and reinfarction than non-smokers (P=0.024). Conclusion • In patients with STEMI, smoking has no protective effect on long-term prognosis. When IMH appears in STEMI patients, smoking has a protective effect on all-cause death, reinfarction and stoke. However, in patients without IMH, smokers have a worse prognosis than non-smokers.

La paradoja de la inmigración: las madres haitianas y latinoamericanas en Chile / The Immigration Paradox: Haitian and Latin American Mothers in Chile

Introducción: Existe información internacional sobre las diferencias en parto prematuro y peso al nacer para madres migrantes de diferentes etnias originarias. El objetivo de este trabajo es evaluar parto prematuro y peso al nacer de madres de nacionalidad diferente, cuyos partos ocurrieron en Chile. Materiales y métodos Se utilizó la base de datos nacional del Departamento de Informática del Ministerio de Salud de Chile. Se incluyeron los recién nacidos del período Septiembre 2012 a Diciembre 2016. Se evaluaron los datos perinatales básicos, parto prematuro, bajo peso al nacer y su relación con la edad gestacional de nacidos de madres chilenas y de otras nacionalidades. Resultados En el periodo estudiado hubo 1.048490 nacimientos, de los cuales 50995 son de madres extranjeras. El porcentaje de nacidos antes de 37 semanas en madres de Bolivia, Colombia, Ecuador, Perú y Venezuela es entre un 4.8 y 7.3 %, versus 8% en madres chilenas. Los percentiles 10 para el peso al nacer entre 30 y 40 semanas para madres chilenas y Haitianas (en paréntesis) expresados en gramos: 1045 (1102), 1195 (1160), 1360 (1370), 1550 (1503), 1750 (1508), 2000 (1669), 2235 (1982), 2500 (2237), 2810 (2607), 2970 (2710), 3080 (2858). Los z-score de madres Haitianas fueron significativamente menores después de las 35 semanas. Conclusiones La paradoja de la inmigración se verifica en la experiencia nacional, con tasas de natalidad prematuras y bajo peso al nacer más favorables para las madres extranjeras en comparación con las mujeres chilenas y con sus países de origen. Las madres afro-caribeñas tuvieron nacimientos con peso menor, en edades gestacionales donde se toman decisiones frecuentes, con diferencias de hasta un 20 % entre las 35- 37 semanas.

SUMMARY The immigration paradox: Haitian and Latin American mothers in Chile Introduction There is international information on the differences in preterm birth and birth weight for migrant mothers of different ethnicities. The objective is to evaluate prematurity and birth weight of mothers of different national origin, whose deliveries occurred in Chile. Materials and methods The national database of the Department of Informatics of the Ministry of Health of Chile was used. Newborns from the period of September 2012 to December 2016 were included. Basic perinatal data, preterm birth, low birth weight and their relationship with the gestational age of babies born to mothers of local origin and other nationalities were evaluated. Results 1,048,490 births, 50,995 foreign mothers were studied. The percentage of those born before 37 weeks of mothers from Bolivia, Colombia, Ecuador, Peru, and Venezuela is between 4.8 and 7.3%, compared to nationals with 8%. The 10th percentiles for birth weight from 30 to 40 weeks for Chilean and Haitian mothers (in parentheses) were (g): 1045 (1102), 1195 (1160), 1360 (1370), 1550 (1503), 1750(1508 ), 2000 (1669), 2235 (1982), 2500 (2237), 2810 (2607), 2970 (2710), 3080 (2858). The z-scores of Haitian mothers were significantly lower. Conclusions The immigration paradox is verified in the national experience, with preterm birth rates and low birth weight more favorable to foreign mothers compared to chileans Afro-Caribbean mothers had births with a lower weight, at gestational ages where relevant decisions are made, with differences of up to a 20% between 35-37 weeks.

El papel de la paradoja de la obesidad y el conteo linfocitario en sepsis / The role of the obesity paradox and lymphocytic count on sepsis / O papel do paradoxo da obesidade e contagem de linfócitos na sepse

Resumen: Introducción: La obesidad es un factor protector para mortalidad en la sepsis, a este fenómeno se le conoce como «paradoja de la obesidad¼. La obesidad es un estado inflamatorio crónico, que incluye mediadores de la inmunidad innata y adaptativa. Un marcador de inmunidad adaptativa es la linfopenia, ésta es relacionada con peor evolución y mayor mortalidad. Objetivo: Determinar la relación del índice de masa corporal (IMC) con conteo linfocitario y su relación con supervivencia en pacientes sépticos. Material y métodos: Estudio de cohortes, retrospectivo, en pacientes con sepsis y/o choque séptico mayores de 18 años, sin enfermedades autoinmunes, ni tratamiento inmunosupresor, determinando IMC y linfopenia. Resultados: Se incluyeron 206 pacientes, 8.7% con peso bajo, 46.6% peso normal, 24.8% con sobrepeso, 19.9% con obesidad. El grupo de mayor mortalidad con linfopenia tuvo los menores valores de IMC 21.37 kg/m2. El análisis de supervivencia reveló que un IMC < 22.5 kg/m2 y linfopenia son factores de riesgo independientes para mortalidad. Conclusiones: La obesidad se relaciona con mayor conteo linfocitario y mayor supervivencia en sepsis y choque séptico, por lo que el IMC y el conteo linfocitario son factores independientes para mortalidad estadísticamente significativos, proponemos la escala APACHE II ajustada con estas variables.

Abstract: Introduction: Obesity is a mortality protector factor in sepsis; this phenomenon is known as «obesity paradox¼. Furthermore, obesity is a chronic inflammatory state in which adaptive and innate immunity mediators play key roles. Lymphopenia is an adaptive immunity marker and it has been related to poor outcomes and greater mortality. Objective: To determine the relationship between body mass index and lymphocyte count and its association with the survival of septic patients. Methods and materials: A cohort retrospective study of patients older than 18 years old with sepsis, septic shock and no history of autoimmune diseases nor immunosuppressor treatments. Outcomes included determining BMI and lymphopenia. Results: 206 patients were included, 8.7% with low weight, 46.6% with normal weight, 24.8% with normal weight, 19.9% with obesity. The group with the lowest BMI (median of 21.37) and lymphopenia was associated with the greatest mortality. The survival analysis revealed that a BMI lower than 22.5 and lymphopenia are independent risk factors for mortality. Conclusions: Obesity is associated to a higher lymphocyte count and a greater survival in sepsis and septic shock. Since BMI and lymphocyte count are statistically significant independent risk factors for mortality, we propose an APACHE II score adjusted to these variables.

Resumo: Introdução: Na sepse, a obesidade é um fator de proteção para mortalidade, denominando esse fenômeno de «paradoxo da obesidade¼. A obesidade é um estado inflamatório crônico, incluindo mediadores da imunidade inata e adaptativa. Um marcador de imunidade adaptativa é a linfopenia, que está relacionada a uma evolução desfavorável e maior mortalidade. Objetivo: Determinar a relação do índice de massa corporal (IMC) com a contagem de linfócitos e sua relação com a sobrevida em pacientes sépticos. Material e métodos: Estudo de coorte, retrospectivo em pacientes com sepse e / ou choque séptico com mais de 18 anos, sem doenças autoimunes ou tratamento imunossupressor, determinando o IMC e a linfopenia. Resultados: Foram incluídos 206 pacientes, sendo 8.7% com baixo peso, 46.6% com peso normal, 24.8% com sobrepeso, 19.9% com obesidade. O grupo com maior mortalidade com linfopenia apresentou os menores valores de IMC de 21.37 kg/m2. A análise de sobrevivência revelou que um IMC < 22.5 kg/m2 e a linfopenia são fatores de risco independentes para a mortalidade. Conclusão: A obesidade está relacionada à maior contagem de linfócitos e maior sobrevida em sepse e choque séptico. Como o IMC e a contagem de linfócitos são fatores independentes para mortalidade estatisticamente significante, propomos a escala APACHE II ajustada com essas variáveis.

O papel do tecido adiposo na obesidade e na insuficiência cardíaca

Introdução. A obesidade, um importante fator de risco para o desenvolvimento da insuficiência cardíaca (IC), é um fator prognóstico protetor. Esse possível paradoxo pode explicar-se pelo papel protetor do tecido adiposo marrom (BAT), das adipocinas anti-inflamatórias e pela conexão do tecido adiposo ao coração mediada pelos peptídeos natriuréticos (NPs). Material e métodos. As evidências sobre os três mecanismos citados são discutidas. Resultados. Em animais e em humanos, tanto obesos como em portadores de IC, há aumento do BAT mas, é menos ativo, com menor expressão de proteína desacopladora tipo 1 (UCP1), limitando seu potencial protetor. A atividade anti-inflamatória de algumas adipocinas está associada à promoção da regeneração do miocárdio, formação de novos vasos sanguíneos, redução da pós-carga, melhora dos processos metabólicos em cardiomiócitos. Recentemente demonstrou-se que NPs, além de seu papel na homeostase circulatória, têm um papel na regulação do consumo energético e na regulação do tecido adiposo, interferindo na liberação de adipocinas. Sabe-se que os NPs estão diminuídos nos obesos, por haver maior clearence ou menor secreção. Conclusão. O papel das adipocinas anti-inflamatórias e a conexão do tecido adiposo ao coração mediada pelos NPs são mecanismos promissores para explicar o paradoxo da obesidade na IC. Localizamos somente dois estudos sobre o papel anti-inflamatório das adipocinas, com evidências diretas. Apesar da existência de inúmeros estudos sobre os NPs, as evidências são menos consistentes. Trata-se de uma área que merece ser acompanhada na tentativa de compreender o paradoxo da obesidade na IC, o que poderia permitir uma melhor abordagem ao paciente acometido por essa síndrome.

Introduction. Obesity, an important risk factor for the development of heart failure (HF), is a protective prognostic factor. This paradox can be explained by the protective role of brown adipose tissue (BAT), anti-inflammatory adipokines and the crosstalk between adipose tissue and heart mediated by natriuretic peptides (NPs). Material and methods. Evidence for these three mechanisms is discussed. Results. In animals and humans models, in both, obese and patients with HF, there is an increase in BAT, but it is less active, with lower expression of uncoupling protein type 1 (UCP1), limiting its protective potential. The antiinflammatory effect of some adipokines is associated with myocardial regeneration, production of new blood vessels, reduction of afterload and potentiation of metabolic processes in cardiomyocytes. It has been shown that NPs, in addition to their role in circulatory homeostasis, play a role in the energy tightening and regulation of adipose tissue, interfering with the release of adipokines. It is known that NPs are decreased in obese, due to a greater clearance or lower secretion. Conclusion. The role of anti-inflammatory adipokines and the crosstalk between adipose tissue and heart mediated by NPs are promising mechanisms to explain the paradox of obesity in HF. We found only two studies on the antiinflammatory role of adipokines, with direct evidence. Despite the existence of numerous studies on NPs, the evidence is less consistent. This area deserves to be followed in an attempt to understand the paradox of obesity in HF, which could allow a better care to the patient affected.

Consideraciones teóricas sobre la perspectiva ecológica-evolutiva del cáncer / Theoretical considerations on the ecological-evolutionary perspective of cancer

RESUMEN El cáncer constituye un serio problema de salud a nivel mundial. La introducción de una perspectiva ecológica y evolutiva de las neoplasias malignas tiene como propósito un enfoque más sistémico y objetivo a la naturaleza de este heterogéneo grupo de enfermedades. Con el objetivo de un acercamiento a las ideas más generalizadas existentes en la actualidad sobre la perspectiva ecológica-evolutiva del cáncer, se realizó la presente revisión. El cáncer es un fenómeno universal que afecta a todas las formas de organismos pluricelulares. El riesgo de desarrollar tumores malignos se encuentra estrechamente relacionado con los patrones de historias de vida trazados por el proceso evolutivo, acorde a la necesidad adaptativa de los organismos a los diferentes nichos ecológicos que ocupan. Existe asociación entre el desarrollo evolutivo de mecanismos protectores contra tumores malignos y el costo evolutivo de estos en términos de éxito reproductivo. El éxito reproductivo parece depender del tamaño corporal, la distribución de energía hacia procesos básicos y el riesgo basal de cáncer. La selección natural favorece mecanismos efectivos, que protejan contra el cáncer siempre que permitan una optimización de otros rasgos que determinen el éxito adaptativo. Las conclusiones derivadas de estos principios ecológicos y evolutivos, deben servir para una mejor caracterización de los factores dependientes tanto de los factores biológicos como de los ambientales que influyen en el riesgo de la carcinogénesis. Más del 90 por ciento del incremento del riesgo basal de cáncer, incluso en especies naturales, obedecen a la actividad humana, y por tanto, pueden ser modificables(AU)

ABSTRACT Cancer is a serious health problem worldwide. The introduction of an ecological and evolutionary perspective of malignant neoplasms is aimed at a more systemic and objective approach to the nature of this heterogeneous group of diseases. This paper will review current thinking in the ecological-evolutionary perspective of cancer. Cancer is a universal phenomenon that affects all forms of multicellular organisms. The risk of developing malignant tumors closely associates to the patterns of life histories traced by the evolutionary process according to the adaptive need of organisms to the different ecological niches they occupy. There is an association between the evolutionary development of protective mechanisms against malignant tumors and their evolutionary cost in terms of reproductive success. The later seems to depend on body size, distribution of energy towards basic processes and basal risk of cancer. Natural selection favors effective mechanisms that protect against cancer if they allow optimization of other traits that determine adaptive success. These ecological and evolutionary principles allow concluding that they should serve to better characterize the factors depending on both biological and environmental factors that influence the risk of carcinogenesis. More than 90 percent of the increase in cancer basal risk, even in natural species, is due to human activity, and therefore, modification is possible(AU)

Alice e os paradoxos da escrita acadêmica / Alice and the academic writing paradoxes / Alice y los paradójicos de la escritura académica

O texto aborda a escrita acadêmica como experiência agonística. Utilizamos o recurso da ficção como estratégia para compor uma narrativa que visa a incidir nos modos de produção de verdades, por meio da convocação de afetos que transcendam o conteúdo da escrita. A experiência agonística é discutida pela personagem Alice, por meio da problematização de três paradoxos: o aspecto informativo e experiencial da escrita na constituição das políticas de produção, o engendramento entre virtualidade e atualização nos processos de subjetivação e a presença-ausente do autor na produção de autoria. Uma posição ético-estético-política é tecida a partir da problematização desses elementos, apostando na potência de um textoexperimentação para provocar fissuras nos modos de produção de conhecimento no âmbito acadêmico.

The text approaches academic writing as an agonistic experience. Fiction discourse is used as a strategy to compose a narrative that aims to delve in truth production modes by means of conjuring affection that transcends the written content. The agonistic experience is discussed by means of three paradoxical problematizations by the character Alice: the informative and personal aspect of writing in constituting production policies, the intertwining between virtuality and the updating of subjectivization processes and the absent-presence of the author on authorship production. An ethical-aesthetical-political approach is woven from the problematization of these elements, leaning on the potency of an experiencing-text to provoke fissures on the production modes of knowledge in the academic scope.

Correlation between different body mass indexes and incidence of digestive carcinoma: a multicentre retrospective study (A report of 95 177 cases) / 中华消化外科杂志

Objective To explore the correlation between different body mass indexes and incidence of digestive carcinoma.Methods The retrospective cohort study was conducted.The data of 95 177 participants (75 909 males and 19 268 females) aged (51± 12)years with the range of 18-98 years who participated health examination at the Kailuan General Hospital,Kailuan Linxi Hospital,Kailuan Zhaogezhuang Hospital,Kailuan Tangjiazhuang Hospital,Kailuan Fan' gezhuang Hospital,Kailuan Jinggezhuang Hospital,Kailuan Lyujiatuo Hospital,Kailuan Linnancang Hospital,Kailuan Qianjiaying Hospital,Kailuan Majiagou Hospital and Kailuan Branch Hospital from July 2006 to December 2015 were collected.According to definition of body mass indexes from Chinese guideline for prevention and control of adult overweight and obesity,all the 95 177 participants were allocated into the 3 groups,including 37 660 with BMI＜24 kg/m2 in the normal BMI group,39 793 with with 24 kg/m2 ≤BMI＜ 28 kg/m2 in the overweight group and 17 724 with BMI≥28 kg/m2 in the obesity group.All participants received the same-order health examinations by the fixed team of doctors in 2006,2008,2010,2012 and 2014 at the same place.Epidemiological investigation,anthropometric parameters and biochemical indicators were collected.Observation indicators:(1) comparisons of clinical characteristics among the 3 groups;(2) incidence of digestive carcinoma in the participants;(3) risk factors analysis affecting new-onset digestive carcinoma;(4) comparisons of the fitting degree of BMI on new-onset digestive carcinoma model;(5) stratified analysis of risk factors affecting new-onset digestive carcinoma at different locations.Measurement data with normal distribution were represented as Mean±SD,and comparisons among groups were analyzed using the one-way ANOVA.Measurement data with skewed distribution were described as M (range),and comparisons among groups were analyzed using the Kruskal-Wallis test.Count data were described as case number and percentage,and comparisons among groups were analyzed using the chi-square test.The cumulative incidence was calculated by the Kaplan-Meier method,and comparisons of incidences among groups were done by the Log-rank test.The incidences of digestive carcinomain patients with different BMI were calculated by person-year incidence (incidence density).The hazard ratio (HR) and 95％ confidence interval (CI) of different BMI (continuous variable and classification variable) on new-onset digestive carcinoma were estimated by the COX proportional hazards regression models.Restrictive cubic spline regression was used to calculate the dose-response relation between the continuous variable and the risks of digestive carcinoma.The fitting degree of BMI on new-onset digestive carcinoma model was calculated by the likelihood ratio test and akaike information criterion (AIC).Results (1) Comparisons of clinical characteristics among the 3 groups:age,sex (male),systolic pressure,diastolic pressure,waistline,total cholesterol (TC),triglyceride (TG),fasting plasma glucose (FPG),C reactive protein,cases with smoking,drinking,physical exercise,positive HBsAg,high salt intake,malignant tumor in immediate family were (51± 13)yeas,28 607,(125±20) mmHg (1 mmHg=0.133 kPa),(80± 11) mmHg,(81±9) cm,(4.9± 1.1) mmol/L,1.05 mmol/L(range,0.75-1.49 mmol/L),(5.3±1.6) mmol/L,0.58 mmol/L (range,0.20-1.60 mmol/L),11 962,6 845,5 676,711,.3 640,1 298 in the normal BMI group and (52±12)years,32 928,(133±21) mmHg,(85±11) mmHg,(89±8)cm,(5.0±1.2) mmol/L,1.39 mmol/L (range,0.99-2.08 mmol/L),(5.6± 1.7)mmol/L,0.84 mmol/L (range,0.33-2.07 mmol/L),12 364,7 413,6 322,839,4 401,1 463 in the overweight group and (51 ± 12) years,14 374,(139 ± 21) mmHg,(88 ± 12) mmHg,(96 ± 9) cm,(5.1 ± 1.2) mmol/L,1.67 mmol/L (range,1.18-2.51 mmol/L),(5.7± 1.8) mmol/L,1.22 mmol/L (range,0.53-2.82 mmol/L),5 092,2 818,2 847,355,2 235,704 in the obesity group,showing statistically significant differences among groups (F=90.60,x2 =576.34,F=2 768.38,3 570.80,22 319.30,256.99,x2 =9 108.21,F=507.11,x2 =3 219.47,52.78,64.38,13.36,0.76,130.39,9.74,P＜0.05).(2) Incidence of digestive carcinoma in the participants:all the 95 177 participants were followed up for 845 085 person-year,1 215 were diagnosed as new-onset digestive carcinoma,with a total person-year incidence of 1.44 thousand person / year.Of 1 215 patients,413 had colorectal-anal cancer,306 had liver cancer,234 had gastric cancer,113 had esophageal cancer,91 had the pancreatic cancer,36 had gallbladder carcinoma or cholangiocarcinoma,25 had intestinal cancer.Three patients had intestinal cancer complicated with colorectal-anal cancer.The person-year incidence of digestive carcinoma was 1.46 thousand person / year,1.37 thousand person / year and 1.53 thousand person / year in the normal BMI group,overweight group and obesity group,respectively.The cumulative incidences of digestive carcinoma in the normal BMI,overweight,obesity group were respectively 11.8‰,10.1‰ and 12.1‰,showing a statistically significant difference among 3 groups (x2=6.13,P＜0.05).There was no statistically significant difference between the normal BMI group and obesity group (x2 =1.07,P＞0.05),and statistically significant differences between the overweight group and normal BMI group and obesity group,respectively (x2=3.90,4.10,P ＜ 0.05).(3) Risk factors analysis affecting new-onset digestive carcinoma.Results of COX proportional hazards regression models showed that continuous BMI was not related factor affecting new-onset digestive carcinoma after adjustment of age,gender,systolic pressure,TC,TG,FPG,smoking,drinking,physical exercise,positive HBsAg,high salt intake,malignant tumor in immediate family (HR=0.99,95％CI:0.98-1.01,P＞0.05).After adding BMI as classification variable in the COX model,risk of new-onset digestive carcinoma in the overweight group was reduced compared with normal BMI group (HR =0.88,0.88,95％CI:0.78-1.01,0.77-0.98,P＜0.05) and risk of new-onset digestive carcinoma in the obesity group was not affected (HR=1.03,1.04,95％CI:0.88-1.20,0.89-1.22,P＞0.05).Results of restrictive cubic spline regression showed a "U" shaped relationship between BMI and incidence risk of digestive carcinoma and the lowest incidence of digestive carcinoma in patients with BMI as 25-27 kg/m2.(4) Comparisons of the fitting degree of BMI on new-onset digestive carcinoma model:multivariate model was constructed after adding risk factors of age,gender,systolic pressure,TC,TG,FPG,smoking,drinking,physical exercise,positive HBsAg,high salt intake,malignant tumor in immediate family,and-2Log L and AIC were 27 175.05 and 27 203.05 for the multivariate model.Then BMI variable was added into the multivariate model,and the-2Log L and AIC of the multivariate model+BMI model were 27 169.53 and 27 201.53,respectively,with a statistically significant difference compared with normal BMI group (x2 =5.52,P＜0.05).(5) Stratified analysis of risk factors affecting new-onset digestive carcinoma at different locations.Results of COX proportional hazards regression models showed risks of new-onset digestive carcinoma in the overweight and obesity groups were reduced compared with normal BMI group (HR=0.57,0.42,95％CI:0.38-0.84,0.23-0.79,P＜0.05) in the esophageal cancer model.Risks of new-onset digestive carcinoma in the overweight group were reduced compared with normal BMI group (HR=0.72,95％CI:0.55-0.93,P＜0.05) and risk of new-onset digestive carcinoma in the obesity group was not affected (HR=1.10,95％CI:0.82-1.47,P＞0.05) in the liver cancer model.Conclusions Participants in the overweight group have the lowest incidence of digestive carcinoma,especially in the esophageal cancer and liver cancer model.Incidence of digestive carcinoma is the lowest with BMI as 25-27 kg/m2.

The Insight Paradox among Outpatients with Schizophrenia / 대한정신분열병학회지

OBJECTIVES: The primary objective was to test the phenomenon known as the insight paradox, which refers to the association between higher levels of insight and lower self-esteem, higher hopelessness, and a higher perception of social prejudice among patients with schizophrenia. METHODS: A total of 216 outpatients with schizophrenia according to the DSM-IV diagnostic criteria were recruited. All participants were receiving ongoing outpatient treatment and were in a stable phase of the disorder. The participants were divided into a good-insight (N=109) and a poor-insight (N=107) group by the direct interview and the mean score of questionnaire. The parameters used for analysis and comparison were demographic variables (age, gender, education), clinical variables (age at onset, number of hospitalizations), self-esteem, hopelessness, self-stigma, and quality of life. RESULTS: Compared with the poor-insight group, the good-insight group was found to have a lower number of hospitalizations, lower self-esteem, higher hopelessness, lower quality of life, and a higher level of internalized stigma. CONCLUSION: The insight can cause the negative consequences in patients with schizophrenia. Therefore, clinicians should pay attention to the negative aspects of insight for improving the quality of life in the treatment of patients with schizophrenia.

Hispanic Ethnicity and the Risk of Cardiovascular Disease in the United States: The Behavioral Risk Factor Surveillance System 2013 / Riesgo cardiovascular entre Hispano-Americanos residiendo en los Estados Unidos: El sistema conductual de vigilancia de factores de riesgo 2013

ABSTRACT Background: Although the leading cause of death among Hispanics living in the United States (US) is cardiovascular disease (CVD), the association between Hispanic ethnicity and CVD has been scarcely explored. Objective: To examine whether being Hispanic is associated with an increased risk of CVD compared with the non-Hispanic US adult population in 2013. Methods: Secondary data analysis of a cross-sectional 2013 Behavioral Risk Factor Surveillance System survey in 2013 (n=486,905). The main exposure variable was Hispanic ethnicity (Mexican, Puerto Rican, Cuban or Spanish origin) and the main outcome variable was self-reported CVD (myocardial infarction/coronary artery disease/angina). The main covariates were sex, age, education, income, healthcare access, exercise, body mass index, current smoking, heavy drinking, diabetes, hypertension and hyperlipidemia. Unadjusted and adjusted logistic regressions were used to assess the effect between ethnicity and self-reported CVD. Odds ratios (OR) and 99% confidence intervals (CI) were calculated. Results: In total, 12% of the study participants were Hispanic (n=57,257). Approximately 24% of Hispanics were 25-34 y/o while (21%) of non-Hispanic were >65 y/o. After adjustment, Hispanics were 30% less likely to report CVD compared with non-Hispanics (OR=0.7; 99%; CI=0.6-0.8). Compared with men, women had a 40% decreased risk of having CVD (OR=0.60; 99% CI=0.5-0.6). Advanced age, lower educational attainment, income <$15,000/year, lack of exercise, smoking, non-heavy drinking, diabetes, hypertension and hyperlipidemia increased statistically significantly the likelihood of reporting CVD. Conclusion: The findings suggest that, in general, Hispanics residing in the US are significantly less likely to self-declare if they had a CVD compared with non-Hispanic Americans. These data suggest that although Hispanics are generally poorer and have less access to education and health services, their self-perceived health is better than in non-Hispanic residents of the US.

Resumen Introducción: Aunque la enfermedad cardiovascular (ECV) es una de las mayores causas de defunción entre los hispanos que viven en los EE. UU, la asociación entre la etnia hispana y la ECV apenas se ha explorado. Objetivo: Examinar si ser hispano se asocia con un mayor riesgo de padecer ECV en comparación con la población adulta no Hispana de los EE. UU, basados en los datos de la encuesta nacional sobre factores de riesgo conductuales del 2013. Métodos: Se realizó un análisis de datos secundario de la información obtenida del Sistema de Vigilancia del Factor de Riesgo Conductual (BRFSS) para estudiar la asociación entre origen étnico (hispanos: mexicano, puertorriqueño, cubano o de origen español vs. no hispanos) y la ECV en los encuestados a través del sistema BRFSS. Utilizamos una regresión logística para obtener modelos ajustados y no ajustados para evaluar el efecto de las características de la población seleccionada en participantes que informaron tener o no ECV. Resultados: En este estudio se incluyeron 486905 adultos, (48% hombres) y 57257 (11,8%) que se autodefinieron como hispanos. Aproximadamente el 24% de los hispanos tenían entre 25 y 34 años, mientras que un 21% de los no hispanos tenían más de 65 años. Después del ajuste de variables, los hispanos tenían un 30% menos de probabilidades de reportar una ECV en comparación con los no hispanos (OR = 0.7, 99% CI = 0.6-0.8); las mujeres mostraron un 40% menos de probabilidades de presentar una ECV (OR = 0,60; IC del 99% = 0,5-0,6). Tener más edad, menos nivel de educación formal, ganar menos de <$ 15000 / año, el sedentarismo, el tabaquismo, el consumo excesivo de alcohol, la diabetes, la hipertensión y la hiperlipidemia aumentaron significativamente la probabilidad de presentar una ECV. Conclusiones: Los hallazgos sugieren que en general, los hispanos que residen en los EE. UU, especialmente mujeres, tuvieron una probabilidad significativamente menor de autoreportar que tuvieron una ECV en comparación con los norteamericanos no hispanos.
