Immunodeficiency-related high-grade B-cell lymphoma with 11q aberration: Further evidence for a lymphoma entity from a patient with simultaneous papillary renal cell carcinoma following pediatric kidney transplant.

Various aggressive lymphomas entities have been associated with immunodeficiency. To provide further evidence that also MYC-negative high-grade B-cell (formerly Burkitt-like) lymphoma with 11q aberrations comprises an immunodeficiency-related subtype, we here conducted a comprehensive pathological and genetic workup of a 25-year-old patient with this type of lymphoma and simultaneous papillary renal cell carcinoma. The patient developed both malignancies following extensive childhood immunosuppression and a kidney transplant.

Fibrin associated large B-cell lymphoma accidentally identified in a breast implant capsule: a molecular report of a rare entity.

Breast implant-associated (BIA) lymphoma is a rare malignancy, typically originating from T-cells; however, few cases of diffuse large B-cell lymphoma (LBCL) have been recently described. These cases share major features: Epstein-Barr virus positivity and a favorable prognosis with surgical intervention alone, hinting at a potential link to fibrin-associated LBCL (FA-LBCL). This study presents the first case of BIA-FA-LBCL in Italy and one of the few assessed from a molecular standpoint so far.

The Possible Involvement of Glucagon-like Peptide-2 in the Regulation of Food Intake through the Gut-Brain Axis.

Food intake regulation is a complex mechanism involving the interaction between central and peripheral structures. Among the latter, the gastrointestinal tract represents one of the main sources of both nervous and hormonal signals, which reach the central nervous system that integrates them and sends the resulting information downstream to effector organs involved in energy homeostasis. Gut hormones released by nutrient-sensing enteroendocrine cells can send signals to central structures involved in the regulation of food intake through more than one mechanism.

Chronic administration of prebiotics and probiotics ameliorates pathophysiological hallmarks of Alzheimer's disease in a APP/PS1 transgenic mouse model.

The gut microbiota (MB), although one of the main producers of Aβ in the body, in physiological conditions contributes to the maintainance of a healthy brain. Dysbiosis, the dysbalance between Gram-negative and Gram-positive bacteria in the MB increases Aβ production, contributing to the accumulation of Aβ plaques in the brain, the main histopathological hallmark of Alzheimer's disease (AD). Administration of prebiotics and probiotics, maintaining or recovering gut-MB composition, could represent a nutraceutical strategy to prevent or reduce AD sympthomathology.
