RESUMO

Breast cancer is one of the main causes of death worldwide. Lately, there is great interest in developing methods that assess individual sensitivity and/or resistance of tumors to antineoplastics to provide personalized therapy for patients. In this study we used organotypic culture of human breast tumor slices to predict the experimental effect of antineoplastics on the viability of tumoral tissue. Samples of breast tumor were taken from 27 patients with clinically advanced breast cancer; slices were obtained and incubated separately for 48 h with paclitaxel, docetaxel, epirubicin, 5-fluorouracil, cyclophosphamide, and cell culture media (control). We determined an experimental tumor sensitivity/resistance (S/R) profile by evaluating tissue viability using the Alamar Blue® metabolic test, and by structural viability (histopathological analyses, necrosis, and inflammation). These parameters were related to immunohistochemical expression of the estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. The predominant histological type found was infiltrating ductal carcinoma (85.2%), followed by lobular carcinoma (7.4%) and mixed carcinoma (7.4%). Experimental drug resistance was related to positive hormone receptor status in 83% of samples treated with cyclophosphamide (p = 0.027). Results suggest that the tumor S/R profile can help to predict personalized therapy or optimize chemotherapeutic treatments in breast cancer.

RESUMO

Background: The cardiovascular sequelae by the SARS-COV-2 infection is prevalent in a significant portion of the recovered patients from the acute presentation of the SARS-COV-2. Actually, the clinic cardiac control of the post-acute COVID syndrome has been working out without a well-established protocol, making the appropriate diagnosis of the cardiac diseases produced by the different damage mechanisms from COVID-19. Objectives: Standardize cardiovascular care and the follow up of COVID-19 survivors in the function on disease severity and identify patients who develop SPC-19A for timely care. Materials and methods: Through an extensive bibliographic review, this article has the purpose of provide the necessary information to make possible the early diagnosis and following of the cardiac complications that has been recorded trough the months after the acute disease from COVID-19.


Antecedentes: Las secuelas cardiovasculares ocasionadas por la enfermedad por coronavirus 2019 (COVID-19) son frecuentes en una importante proporción de los pacientes recuperados del cuadro agudo de la enfermedad. Hasta el día de hoy el seguimiento cardiológico del síndrome agudo post-COVID-19 (SPC-19A) se ha realizado de forma heterogénea y sin directrices que permitan al clínico identificar oportunamente los cambios que preceden a enfermedades cardiológicas derivadas de los distintos mecanismos de daño inducidos por COVID-19. Objetivos: Estandarizar la atención y seguimiento cardiovascular de los supervivientes de COVID-19 en función de la gravedad de la enfermedad e identificar a los pacientes que desarrollen SPC-19A para su atención oportuna. Material y métodos: Mediante una revisión extensa de bibliografía, este documento tiene la intención de unificar y proporcionar la información necesaria para diagnosticar y dar seguimiento a las complicaciones cardiacas que se han documentado en los meses posteriores a la resolución de la COVID-19 aguda.

RESUMO

INTRODUCCIÓN: A través de la Red Ministerial de Investigación en Salud (REMINSA) se actualizó el estado de situación de las áreas provinciales de investigación en salud pública. MÉTODOS: Se realizaron reuniones virtuales de debate con los referentes REMINSA y una encuesta en Google Forms® sobre funcionamiento normativo, organizacional, presupuestario, alcance de tareas y necesidades de mejoras. RESULTADOS: Se recibieron 21 respuestas de un total de 21 provincias con referentes. Se verificó la existencia de un amplio marco de normativas regulatorias de la investigación en salud humana y, en menor medida, para impulsar la investigación en el marco de la salud pública. El 71% tiene cierta estructura institucional, el 20% ofrece becas de investigación, y el 20% posee residencias con perfil en investigación. La principal actividad es la regulación o participación en comités de ética. La promoción, difusión de resultados y elaboración de proyectos de investigación basada en evidencia quedaron relegadas (20%). Las áreas de investigación están consolidadas en la mayoría de las provincias. DISCUSIÓN: El desafío consiste en promover el desarrollo de estos sistemas en las provincias que no cuentan con áreas ministeriales y fortalecer las provincias que sí las poseen. REMINSA ha identificado oportunidades de mejorar la comunicación entre jurisdicciones, las normativas de promoción de la investigación y el trabajo en red para la investigación, la gestión y la toma de decisiones.

RESUMO

Macroalgae represent an important source of bioactive compounds with a wide range of biotechnological applications. Overall, the discovery of effective cytotoxic compounds with pharmaceutical potential is a significant challenge, mostly because they are scarce in nature or their total synthesis is not efficient, while the bioprospecting models currently used do not predict clinical responses. Given this context, we used three-dimensional (3D) cultures of human breast cancer explants to evaluate the antitumoral effect of laurinterol, the major compound of an ethanolic extract of Laurencia johnstonii. To this end, we evaluated the metabolic and histopathological effects of the crude extract of L. johnstonii and laurinterol on Vero and MCF-7 cells, in addition to breast cancer explants. We observed a dose-dependent inhibition of the metabolic activity, as well as morphologic and nuclear changes characteristic of apoptosis. On the other hand, a reduced metabolic viability and marked necrosis areas were observed in breast cancer explants incubated with the crude extract, while explants treated with laurinterol exhibited a heterogeneous response which was associated with the individual response of each human tumor sample. This study supports the cytotoxic and antitumoral effects of laurinterol in in vitro cell cultures and in ex vivo organotypic cultures of human breast cancer explants.

RESUMO

BACKGROUND: Patients under 45 years with gastric cancer are associated with a poor prognosis. Recent studies report that the 5-year survival is better in younger patients after curative resection. OBJECTIVE: To determine if prognostic factors such as age under 45 years old, anaemia, weight loss, tumour differentiation, histological sub-type, depth of invasion, and lymph node involvement, reduce the survival of patients with resectable advanced gastric adenocarcinoma undergoing gastrectomy with limited and extended lymphadenectomy. MATERIALS AND METHODS: This study included a cohort of consecutive cases treated in the Sarcomas Department of the Oncology Hospital of the Centro Médico Nacional Siglo XXI, of the Instituto Mexicano del Seguro Social, during the period between January 2000 and December 2006. RESULTS: Of the total of 588 patients evaluated, 112 (19%) were under 45 years, 43% classified as Borrmann IV, and 36% as Borrmann III. Metastatic disease was present in 39.3%, localised diffuse in 12.5%; lower resectability 52.7 vs. 61.3% in older than 45 years. At the end of the study 29.5% of patients under 45 years were alive; no recurrence in 26.8%, with an overall survival of 58.6±4.3 months, compared with 18.3% of patients alive over 45 years, 17.9% disease-free, and with overall survival 35.2±4.3 months resectable disease. CONCLUSIONS: Patients under 45 years have a better survival after a two-year disease-free period.

RESUMO

Tobacco smoking is the primary risk factor for chronic obstructive pulmonary disease (COPD). However, recent epidemiological studies have established domestic exposure to wood smoke and other biomass fuels as additional important risk factors, characteristic in developing countries. Oxidative stress is one of the mechanisms concerned with pathogenesis of COPD. However, the molecular mechanisms involved in the onset and progress of COPD associated with biomass and specifically that derived from wood smoke exposure remain unknown. We analyzed the relationship between forced expiratory volume in first second (FEV(1)) with plasma malondialdehyde (MDA) concentration and activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), and glutathione-S-transferase (GST) in COPD patients associated with wood smoke (WSG; n = 30), tobacco smoking (TSG; n = 30), and healthy control subjects (HCG; n = 30). Differences between FEV(1) from WSG and TSG (58 +/- 22% and 51 +/- 24%, respectively) with HCG (100 +/- 6%) were observed (P < 0.01). Plasma MDA concentration was higher in both WSG and TSG (1.87 +/- 0.81 and 1.68 +/- 0.82 nmol/mL, respectively) compared with HCG (0.42 +/- 0.17 nmol/mL; P < 0.01). SOD activity showed a significant increase in both WSG and TSG (0.36 +/- 0.12 and 0.37 +/- 0.13 U/mL) compared with HCG (0.19 +/- 0.04 U/mL; P < 0.01). No differences were shown regarding GPx, GR, and GST activities between COPD and control groups. Inverse correlations were founded between MDA and SOD with FEV(1) in both COPD patients and control subjects (P < 0.001). These results indicate a role for oxidative stress in COPD associated with wood smoke similar to that observed with tobacco smoking in subjects who ceased at least 10 years previous to this study.

RESUMO

OBJECTIVE: We present a retrospective review of urological complications following kidney transplantation in two medical centers in the Mexican state of Veracruz using Lich-Gregoir extravesical ureteroneocystostomy during a 4-year period. METHODS: Records from 242 patients from January 2003 to November 2007 were reviewed. Standard technique for organ procurement, open nephrectomy and kidney transplant was performed. EVU was used in all patients. Urological complications and management are reported. RESULTS: There were 19 complications recorded in 18 patients (7.8%). Sixteen kidneys were obtained from living donors. Urinary leak was the most common complication (4.5%) followed by ureteral stenosis (1.6%), vesicoureteral reflux (1.2%) and ureteral necrosis (0.4%) Most patients were treated with Foley catheter (42%), Boary flap (26%) and nephrostomy (15%); 1.23% grafts were lost associated with urological complications. CONCLUSIONS: Renal transplantation should incur few urological complications. Attention to technical details should be paid to avoid major complications. Early evaluation to correct complications reduces sepsis, morbidity and the risk of losing graft function.

RESUMO

Objetivo: Revisión de las complicaciones urológicas posteriores al trasplante renal en dos centros hospitalarios utilizando la técnica de ureteroneocistostomía extravesical de Lich-Gregoir en un periodo de cuatro años. Material y métodos: Se revisaron los expedientes de 242 pacientes en quienes se llevó a cabo trasplante renal de enero de 2003 a noviembre de 2007. En todos los pacientes se realizó ureteroneocistostomía extravesical. Se informaron todas las complicaciones urológicas y su manejo. Resultados: Se registraron 19 complicaciones en 18 pacientes, con una incidencia de 7.8 %; 16 riñones se obtuvieron de donadores vivos. Las complicaciones más comunes fueron fuga de orina (4.5 %), estenosis urinaria (1.6 %), reflujo vesicoureteral (1.2 %) y necrosis ureteral (0.4 %). La mayoría de los pacientes fueron tratados con sonda de Foley (42 %), colgajo de Boary (26 %) y nefrostomía (15 %). La pérdida del injerto renal se asoció a complicaciones urológicas en 1.23 % Conclusiones: El trasplante renal debe incurrir en pocas complicaciones urológicas, por lo que debe cuidarse los detalles técnicos. La evaluación temprana para corregir las complicaciones reduce la sepsis, morbilidad y el riesgo de pérdida del injerto.
