RESUMO
A significant public health issue worldwide is metabolic syndrome, a cluster of metabolic illnesses that comprises insulin resistance, obesity, dyslipidemia, hyperglycemia, and hypertension. The creation of natural treatments and preventions for metabolic syndrome is crucial. Chitosan, along with its nanoformulations, is an oligomer of chitin, the second-most prevalent polymer in nature, which is created via deacetylation. Due to its plentiful biological actions in recent years, chitosan and its nanoformulations have drawn much interest. Recently, the chitosan nanoparticle-based delivery of CRISPR-Cas9 has been applied in treating metabolic syndromes. The benefits of chitosan and its nanoformulations on insulin resistance, obesity, diabetes mellitus, dyslipidemia, hyperglycemia, and hypertension will be outlined in the present review, highlighting potential mechanisms for the avoidance and medication of the metabolic syndromes by chitosan and its nanoformulations.

Sarcoma of the penis is rare. We report an angiosarcoma that was essentially an incidental finding, despite the presence of metastatic lesions, in a 46-year-old man who presented with hematemesis and melena. The diagnosis of the primary lesion was confirmed by histology, and the presence of secondary lesions by fine needle aspiration cytology. The patient was given one dose of chemotherapy, but died of a myocardial infarction before being able to receive further treatment. The literature pertaining to this very unusual lesion is discussed.
