Introduction: It has been postulated the relationship between presence of cardiometabolic diseases with mental health problems, particularly depression. Objectives: To determine the association between cardiometabolic diseases and presence of depressive symptoms, evaluated by PHQ-9 questionnaire, in patients attended at the outpatient clinic of internal medicine service at Hospital Nacional Hipolito Unanue. Methods: Observational analytical cross-sectional study. Cardiometabolic disease was defined as the presence of diabetes mellitus, high blood pressure, dyslipidemia, and/or obesity. The PHQ-9 questionnaire was used to evaluate the presence of symptoms suggestive of depression. The association was evaluated crude and adjusted for possible confounders. For the multivariate analysis, a Poisson regression model was used to find prevalence ratios with their respective 95% confidence intervals. A p<0.05 was considered statistically significant. Results: 252 patients were included, of which 205 (81,4%) presented cardiometabolic diseases and 181 (71,9%) presented symptoms consistent with some grade of depression. The presence of cardiometabolic diseases was associated with depressive symptoms both in the crude analysis (PRc 1.43; CI 95% 1.08-1.89; p=0.012) and in the adjusted one (PRa 1.31; CI 95% 1.00-1.71; p=0.048). Additionally, an association was found between female sex and depressive symptoms (PRa 1,35; CI 95% 1,11-1,63; p=0,002). Conclusions: The presence of cardiometabolic diseases was associated with the presence of depressive symptoms in patients seen at the outpatient clinic of internal medicine. The mental health approach should be an integral part of the multidisciplinary management for the patient with cardiometabolic disease.

Resumen Introducción: Se ha postulado la relación entre la presencia de enfermedades cardiometabólicas con problemas de salud mental, en particular la depresión. Objetivos: Determinar la asociación entre la presencia de enfermedades cardiometabólicas y la presencia de sintomatología depresiva evaluada mediante el cuestionario PHQ-9 en pacientes atendidos en consultorios externos de medicina interna del Hospital Nacional Hipólito Unanue. Metodología: Estudio observacional, analítico, transversal. Se definió enfermedad cardiometabólica como la presencia de diabetes mellitus, hipertensión arterial, dislipidemia, y/u obesidad. Se utilizó el cuestionario PHQ-9 para evaluar la presencia de síntomas sugerentes de depresión. Se evaluó la asociación cruda y ajustada a posibles confusores. Para el análisis multivariado se utilizó un modelo de regresión de Poisson para hallar razones de prevalencia con sus respectivos intervalos de confianza al 95%. Se consideró un p<0,05 como estadísticamente significativo. Resultados: Se incluyeron 252 pacientes, de los que 205 (81,4%) presentaron enfermedades cardiometabólicas y 181 (71,9%) presentaron síntomas consistentes con algún grado de depresión. La presencia de enfermedades cardiometabólicas se asoció a síntomas depresivos tanto en el análisis crudo (RPc 1,43; IC 95% 1,08-1,89; p=0,012) como en el ajustado (RPa 1,31; IC 95% 1,00-1,71; p=0,048). Adicionalmente se encontró asociación entre el sexo femenino y sintomatología depresiva (RPa 1,35; IC 95% 1,11-1,63; p=0,002). Conclusiones: La presencia de enfermedades cardiometabólicas se asoció con la presencia de síntomas depresivos en pacientes atendidos en la consulta externa de medicina interna. El abordaje de la salud mental debe ser parte integral del manejo multidisciplinario del paciente con enfermedad cardiometabólica.

Tuberculosis (TB) is an infectocontagious respiratory disease caused by members of the Mycobacterium tuberculosis complex. A 7 base pair (bp) deletion in the locus polyketide synthase (pks)15/1 is described as polymorphic among members of the M. tuberculosis complex, enabling the identification of Euro-American, Indo-Oceanic and Asian lineages. The aim of this study was to characterise this locus in TB isolates from Mexico. One hundred twenty clinical isolates were recovered from the states of Veracruz and Estado de Mexico. We determined the nucleotide sequence of a ± 400 bp fragment of the locus pks15/1, while genotypic characterisation was performed by spoligotyping. One hundred and fifty isolates contained the 7 bp deletion, while five had the wild type locus. Lineages X (22%), LAM (18%) and T (17%) were the most frequent; only three (2%) of the isolates were identified as Beijing and two (1%) EAI-Manila. The wild type pks15/1 locus was observed in all Asian lineage isolates tested. Our results confirm the utility of locus pks15/1 as a molecular marker for identifying Asian lineages of the M. tuberculosis complex. This marker could be of great value in the epidemiological surveillance of TB, especially in countries like Mexico, where the prevalence of such lineages is unknown.

Three superoxide dismutase isoenzymes of different cellular location were detected in an homogenate of Thrichuris ovis. Each of these molecular forms was purified by differential centrifugation and precipitation with ammonium sulphate, followed by chromatography on DEAE-cellulose and Sephadex G-75 columns. The activity levels of the two molecular forms detected in the mitochondrial (one cyanide sensitive Cu-Zn-SOD and the other cyanide intensitive Mn-Sod were higher than that of the superoxide dismutase detected in the cytoplasmic fraction (cyanid sensitive Cu-Zn-SOD). All the mollecular forms present evident differences to the SODs contained in the host liver. Molecular mass and some of the physical and chemical aproperties of the enzyme was determined for all three molecular forms. An inhibitory effect on the SOD of the parasite an the host was detected with a series of compounds, some of wich markedly inhibited parasite ensyme but not host enzyme.

The inhibitor effect on the Glycogen synthetase (E.C.2.4.1.11) activity by four anthelmintics: Mebendazole, Parbendazole, Albendazole and Thiabendazole was determinated. The most inhibitor effect of Parbendazole on A. suum, F. hepatica and M. expansa, was observed. The lowest inhibitor effect of Thiabendazole, on all cases, was also observed. The aim of our study, and further studies on the same line, are to provide new reports about the unknown locus of actuation of these anthelmintics.

Se ha determinado el effecto inhibidor sobre la actividad Glucogeno sintetasa (E.C.2.41.11) por parte de cuatro antihelminticos: Albendazol, Mebendazol, Parbendazol y Tiabendazol. Observandose que en todos los casos, es el Parbendazol quien ha demostrado un mayor poder inhibidor sobre la glucógeno sintetasa de Ascaris suum, Fasciola hepatica y Moniezia expansa. El Tiabendazol es el anti-helmintico que menor efecto inhibidor ha presentado sobre la enzima en los tres parasitos objeto de nuestro estudio. Con el presente trabajo y otros previstos en la misma linea, se pretende aportar nuevos datos acerca del aun desconocido locus de acción de estos antihelminticos.
