Importance of Evaluating Cardiovascular Risk and Hepatic Fibrosis in Patients With Newly Diagnosed Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) is a well-recognized health problem, with an estimated worldwide prevalence of 25%.1 It is associated with metabolic syndrome (MetSx) and complications such as cirrhosis and hepatocellular carcinoma. However, the main cause of death in patients with NAFLD is derived from cardiovascular disease, and outcome seems to be determined by the degree of hepatic fibrosis.2 The prevalence of NAFLD and associated cardiovascular risk factors in asymptomatic patients in Mexico are poorly documented, despite having one of the highest rates of obesity and metabolic syndrome worldwide.3.

Relación entre hallazgos radiológicos e inmunofenotipos tumorales de pacientes con cáncer de mama / Relationship between radiological findings and immunophenotyped in breast cancer

Resumen OBJETIVO: Evaluar la relación entre los hallazgos radiológicos e inmunofenotipos tumorales de pacientes con cáncer de mama. MATERIALES Y MÉTODOS: Estudio observacional, retrospectivo y transversal, efectuado en el Hospital ABC de la Ciudad de México, entre 2013 y 2017. Se incluyeron pacientes con diagnóstico de cáncer de mama establecido por biopsia percutánea o escisional, que contaran con estudios de inmunohistoquímica e imagen (mastografía, ultrasonido o ambos). Para evaluar la relación entre las características morfológicas de las lesiones observadas en los estudios radiológicos y el inmunofenotipo se utilizó la prueba de χ2. RESULTADOS: Se registraron 182 pacientes. En cuanto a las características de las lesiones se encontró relación significativa entre las masas de morfología irregular con bordes espiculados y las calcificaciones agrupadas con tumores luminales, y entre las calcificaciones de morfología amorfa con los tumores luminales A y las pleomórficas finas con los tumores luminales B. CONCLUSIÓN: Existe relación entre los hallazgos morfológicos por imagen y el inmunofenotipo de los tumores mamarios. Es importante que el médico radiólogo especialista en imagen mamaria conozca esta relación, con la finalidad de proporcionar información de la inmunohistoquímica al momento del estudio diagnóstico de imagen.

Abstratc OBJECTIVE: Establish if there is a relationship between the radiological findings and the immunophenotype of breast cancer. MATERIALS AND METHODS: An observational, cross-sectional, retrospective study realized at the ABC Medical Center, over a period of 4 years, that included patients diagnosed with breast cancer performed by percutaneous or excisional biopsy, with an immunohistochemical study and images (mammography and/or ultrasound). The relationship between the morphological characteristics of the lesions observed in the radiological studies and the immunophenotyped was studied by means of the χ2 test. RESULTS: We included 182 patients, among the characteristics of the lesions we found a significant relationship between the masses of irregular morphology with spiculate edges and the calcifications grouped with luminal tumors; calcifications of amorphous morphology with luminal A and pleomorphic fine tumors with luminal B. CONCLUSION: The results suggest that there is a relationship between the morphological findings by imaging and the immunophenotype of mammary tumors.

The Effect of Dietary Supplementation With Curcumin on Redox Status and Nrf2 Activation in Patients With Nondiabetic or Diabetic Proteinuric Chronic Kidney Disease: A Pilot Study.

OBJECTIVE: Chronic kidney disease (CKD) is a worldwide public health problem, and proteinuria may accelerate the progression of CKD, being oxidative stress a common mechanism in nondiabetic or diabetic proteinuric kidney disease. This study was designed to evaluate the effect of the dietary supplementation with curcumin (CUR) on the redox status and the nuclear factor erythroid 2-related factor 2 (Nrf2) activation in patients with nondiabetic or diabetic proteinuric CKD. DESIGN: Randomized double-blind placebo-controlled clinical trial. SUBJECTS: A total of 101 Mexican patients from the National Institute of Cardiology "Ignacio Chavez", with nondiabetic or diabetic proteinuric CKD (proteinuria ≥ 1 g protein/24 hours), aged 20 to 70 years; 60% were male, and 51% were diabetic. INTERVENTION: Patients with nondiabetic proteinuric CKD received placebo (n = 26) or CUR 320 mg/day (n = 24) for 8 weeks, and patients with diabetic proteinuric CKD were intervened with placebo (n = 23) or CUR 320 mg/day (n = 28) for the same period. MAIN OUTCOME MEASURE: Anthropometrical, clinical, and biochemical characteristics, as well as oxidative stress markers, antioxidant enzyme activities and Nrf2 activation were evaluated at baseline and after intervention. RESULTS: The intervention with CUR did not improve proteinuria, estimated glomerular filtration rate, or lipid profile. However, in plasma, CUR attenuated lipid peroxidation in individuals with nondiabetic proteinuric CKD (P<.05) and enhanced the antioxidant capacity in subjects with diabetic proteinuric CKD (P<.05). No effect of CUR was observed on the antioxidant enzymes activities or Nrf2 activation. CONCLUSIONS: Dietary supplementation with CUR has the potential to reduce oxidative stress in Mexican patients with nondiabetic or diabetic proteinuric CKD. Studies with higher doses of CUR and longer follow-up are granted to confirm our findings.
