Menopause imposes a dramatic fall in estrogens, which is followed by an increase in the proportion of fat. The rising androgen/estrogen ratio along the menopause transition favors the accumulation of central fat, which contributes to insulin resistance and a series of concatenated effects, leading to a higher incidence of metabolic syndrome. The modulatory effect of diet on the metabolic syndrome phenotype has been shown for the Mediterranean diet, and nuts are key determinants of these health benefits. This review of the impact of nuts on the risk factors of the metabolic syndrome cluster examined studies-prioritizing meta-analyses and systemic reviews-to summarize the potential benefits of nut ingestion on the risk of metabolic syndrome associated with menopause. Nuts have a general composition profile that includes macronutrients, with a high proportion of unsaturated fat, bioactive compounds, and fiber. The mechanisms set in motion by nuts have shown different levels of efficacy against the disturbances associated with metabolic syndrome, but a beneficial impact on lipids and carbohydrate metabolism, and a potential, but minimal reduction in blood pressure and fat accumulation have been found.

The round block oncoplastic technique has proven to be a safe surgical approach in the management of breast cancer tumours. This procedure is useful to achieve resection of large tumours while maintaining a good cosmetic outcome. Recently, the safety of this technique has allowed its use in the treatment of other pathologies without complications. On the other hand, lipomas are the most frequent tumours in the chest wall. However, only 1% of them are larger than 10cm. In giant lipomas, a complete resection is needed to allow a complete anatomopathological study. We report a case of a 50-year-old man with a soft mass in the right breast, a subpectoral lipoma of 25x23x12 cm, without invasion of adjacent vital structures was diagnosed using computed tomography (CT) scan. Due to the benign characteristics, a resection was performed using the round-block technique. The postoperative course was uneventful and the patient was discharged 24 hours after the surgery., La técnica oncoplástica de Round-Block es un abordaje seguro y ya utilizado en la cirugía del cáncer de mama. Es utilizada en la resección de grandes tumores centrales de la mama con muy buen resultado estético. Recientemente, esta técnica también ha sido usada en la cirugía de otras patologías mamarias sin complicaciones descritas. Por otro lado, los lipomas son los tumores más frecuentes de la pared torácica. Sin embargo, solo un 1% de ellos tienen un tamaño mayor de 10cm. En estos “lipomas gigantes” una extirpación amplia es requerida para poder tener un estudio anatomopatológico definitivo. Presentamos el caso de un varón de 50 años con una masa blanda en mama derecha, en las pruebas de imagen realizadas se evidencio un lipoma de 25x23x12cm de tamaño sin invasión de las estructuras vecinas. Debido a las características benignas de la lesión, se llevó a cabo una resección mediante la técnica de Round-Block unilateral. El postoperatorio trascurrió sin incidencias y el paciente fue dado de alta a las 24h de la cirugía.
