Introduction: Ultrasound is a non-invasive, low-cost technique that does not use ionising radiation and provides a “real-time” image, and for these reasons, this method is ideal in several situations. Purpose: To demonstrate breast ultrasound evaluation as a first-line diagnostic method and to evaluate the variation of breast characteristics with age. Material and Methods: A total of 105 women with a mean age of 30 years participated and were divided into three age groups: 18–39, 40–59, and 60–79 years, excluding participants subject to mastectomy. After completing the informed consent, all participants answered personal and sociodemographic questions, such as personal and family history, menstrual cycle, pregnancy, ultrasound, and mammography, among others. They were then submitted to a bilateral breast ultrasound examination. Subsequently, all the images and their data were analysed, and a technical report of the examination was given to all the participants. Results: A total of 105 women with a mean age of 30 years participated, 58 of whom underwent the examination for the first time. In 31, changes (of which only 7 were known) were diagnosed. It was verified that, according to age group, the density of the breast stroma varied; older women have less breast density. Conclusions: Ultrasound is a good method for breast evaluation and can be considered important for the early evaluation of breast pathology and follow-up of the pathology.

Sarcopenia may be described as a muscular disease associated with unfavourable outcomes. Sarcopenic obesity refers to the concomitant presence of sarcopenia and obesity. The best approach to these pathologies is still not determined. Our goal was to review the current knowledge regarding nutrition as a therapeutic option in the treatment of these conditions. From a total of 1024 articles obtained from medical databases, nine were included in the narrative review. Supplementation of vitamin D alone was not associated with significant differences. Protein supplements, especially those rich in leucine, have been commonly used in the included studies, with potential benefit in some muscle parameters such as muscle mass. Benefits of supplementation in sarcopenic obesity are less clear. There was significant heterogeneity between the included studies in many parameters. Therefore, clear and valid conclusions are still not possible, however leucine enriched protein supplements might be an interesting option. Further research is needed.
