Expression and Significance of TIPE2 in Ulcerative Colitis / 胃肠病学

Background:TIPE2 is a newly identified negative regulator of innate and adaptive immunity that maintains immune homeostasis and immune tolerance. It has been demonstrated that TIPE2 is expressed in a wide variety of tissues and organs in humans. Aims:To investigate the expression of TIPE2 in peripheral blood and colonic mucosa of patients with ulcerative colitis(UC)and non-UC subjects,and to explore the role of TIPE2 in the initiation and development of UC. Methods:Forty-two peripheral blood samples and 30 colonic mucosa samples from patients with active UC were collected during Jan. 2015 to Aug. 2016 at the Second Affiliated Hospital of Xian Jiaotong University. Peripheral blood and colonic mucosa samples from non-UC subjects were served as controls. Real-time PCR and immunohistochemical staining were used to detect the mRNA and protein expressions of TIPE2 in peripheral blood mononuclear cells and colonic mucosal tissues, respectively. Results:Expression level of TIPE2 mRNA in peripheral blood of UC patients had a trend to increase but no significant difference was found between UC patients and the controls(P >0.05). When classified by Truelove-Witts severity index,there was no significant difference among patients with severe,moderate and mild UC(P >0. 05). Expression level of TIPE2 protein was significantly higher in colonic mucosa of UC patients than that of the controls(P<0.05);the expression level increased with increase of histological grade of UC,but the difference was not statistically significant(P > 0.05). Conclusions:Increased colonic expression of TIPE2 might contribute to the initiation and development of UC.

Síndrome metabólico en niños: problemática, componentes y criterios diagnósticos / Metabolic syndrome in children: issues, components and diagnostic criteria

RESUMEN Antecedentes el síndrome metabólico en niños aumenta el riesgo de diabetes mellitus tipo 2 y enfermedad cardiovascular en la adultez. Objetivo describir los componentes del síndrome metabólico en niños, su prevalencia y criterios diagnósticos propuestos por diferentes organizaciones y autores. Materiales y métodos se realizó una búsqueda bibliográfica en las siguientes bases de datos: Pubmed, Science Direct, Embase, Lilacs y Scielo. Resultados y discusión varias organizaciones han establecido definiciones para diagnosticar el síndrome metabólico en niños, algunas abordando criterios utilizados en adultos o adoptando puntos de corte derivados de poblaciones seleccionadas como niños obesos o sin incluir niños pre-adolescentes, aduciendo en estos últimos una baja prevalencia de alteraciones. Así, la prevalencia de este síndrome en una misma población puede variar (0,9 a 11,4%) según la definición empleada. Sin embargo, dicha prevalencia aumenta con el grado de obesidad infantil y se han demostrado prevalencias altas en pre-púberes, independiente de la clasificación empleada. Recientemente, se propuso usar puntajes continuos para mejorar la evaluación en niños. Conclusión los puntos de corte actualmente empleados ponderan de forma diferente los componentes del síndrome metabólico. Por tanto, se recomienda emplear percentiles según edad, sexo y población para cada componente y evaluar la utilidad de puntajes continuos en esta población.

ABSTRACT Background The metabolic syndrome in children increases the risk for type 2 diabetes and cardiovascular disease in adulthood. Aim To describe the components of metabolic syndrome in children, their prevalence, and diagnostic criteria proposed by different authors and organizations. Materials and methods A literature search of articles published in Pubmed, Science Direct, Embase, Lilacs and Scielo databases was conducted. Results and discussion: Several organizations have established definitions for metabolic syndrome diagnosis in children, some including criteria used for adults or adopting cutoffs derived from selected populations such as obese children or without including pre-adolescent children, arguing a low prevalence of alterations in these. Thus, the prevalence of metabolic syndrome in a particular population varies (0,9% to 11,4%) according to the definition used. However, this prevalence increases according to the obesity grade, and a high prevalence in pre-pubers has been reported, independent of the classification used. Recently, it was proposed the use of a continuous score to improve the metabolic syndrome evaluation in children. Conclusion: The cutoffs currently used give different weighting for each component of metabolic syndrome. Therefore, it is recommended the use of percentiles according to sex and age and population for each component and to evaluate the utility of continuous scores in this population.

Declaración de Acapulco: propuesta para la reducción de la incidencia de la diabetes en México / The "Declaración de Acapulco": a proposal to reduce incidence of diabetes in Mexico

Type 2 diabetes is the main health problem in Mexico. The growing number of cases, the high percentage of individuals with chronic complications and the treatment's cost are among the explanations for the inability in the control of this disease. Diabetes prevention is most likely to reduce the rate of growth of this diabetes burden on our health system. At- risk individuals can be identified and several interventions have proved to be effective in decreasing diabetes incidence. Diabetes prevention related interventions can become a reality with the active participation of the government and society. Thus, a joint collaboration between the medical community, the government and society is needed to phase out the diabetes epidemic. Published diabetes prevention programs were reviewed and interventions feasible for Mexico were summarized in a document called "Declaración de Acapulco". This paper was reviewed and approved by the Sociedad Mexicana de Nutrición y Endocrinología; additional endorsement was obtained from several Mexican and international societies and institutions. The manuscript describes several initiatives, which can be applied in schools, work places, primary health services and by the government. Some of these are focused on the general population; others are applicable to at-risk individuals. The "Declaración de Acapulco" is a-call-for-action position directed towards the whole society and designed to achieve effective diabetes prevention.

La diabetes es el principal problema de salud en México. El número creciente de casos, el elevado porcentaje que desarrollan complicaciones tardías y el costo del tratamiento hacen insuficientes los esfuerzos para confrontarla. La prevención de la diabetes es la forma más plausible para modificar el crecimiento de la epidemia. Los sujetos que desarrollarán la enfermedad pueden ser detectados y existen intervenciones que disminuyen la incidencia de la enfermedad. Las estrategias para la prevención de la diabetes sólo pueden ser llevadas a la práctica con la intervención de entidades gubernamentales y con el consenso de la sociedad. Por ello, se requiere un esfuerzo conjunto de la comunidad médica, del gobierno y de la sociedad para confrontar la epidemia de diabetes. Se revisaron los programas de prevención reportados en la literatura y se generó un documento, llamado "Declaración de Acapulco" que resume las maniobras que se consideraron factibles en nuestro país. El documento fue avalado por la Sociedad Mexicana de Nutrición y Endocrinología; también, recibió el aval de diversas sociedades e instituciones de México y otros países. El manuscrito describe iniciativas a realizar en escuelas, sitios de trabajo, servicios de salud y en el gobierno. Algunas acciones están dirigidas para la población general; otras son aplicables para sujetos en riesgo. La "Declaración de Acapulco" es un exhorto a la sociedad a tomar una actitud proactiva en la prevención de la diabetes.
