Introduction: The Disorders of Sex Development (DSDs) may arise from various genetic disorders therefore cytogenetic studies are necessary to determine the chromosomal sex. The 45,X/46,XY karyotype is considered a mixed gonadal dysgenesis (MGD) and the mosaicism in this condition has a low incidence: 1.5 per 10 000 newborns, characterized by a broad phenotypic spectrum.Objective: The aim of this report is to present a mexican newborn female patient with ...

Introduction: There is scarcity of data on the recurrence and/or progression (R/P) rate in nonfunctioning pituitary adenomas (NFPAs) after surgery and the risk factors that can predict this outcome. So the aim of this study was to analyze a large series of NFPAs with a long follow-up after surgery, focusing on the evaluation of R/P rate and the risk factors associated with it.Methods: Retrospective cohort analysis of 164 patients with NFPAs from 3 differ...

Introduction: Nutritional status in patients with neuroendocrine tumors (NETs), especially with gastroenteropancreatic origin, may be affected and have an impact on prognosis and survival. Different techniques are currently available to assess nutritional status, but not all of them are accessible in routine clinical practice. In this context, Body composition of NET patients was calculated by computed tomography (CT) at L3 level to evaluate its importance on clinical prognosi...

Aims: A few studies have shown disturbances in the hypothalamic-pituitary-adrenal (HPA) axis in chronic-kidney-disease (CKD), of unknown extent and clinical implications. We aimed to study the HPA axis in patients with CKD and its association with kidney impairment and metabolic disturbances.Methods: Cross-sectional controlled study. Patients with CKD stages I-II (estimated glomerular filtration rate [eGFR] through CKD-EPI equation >60), stage III (e...

Hormonal signalling plays a key role in the progression of metabolic (dysfunction)-associated fatty liver disease (MAFLD) to hepatocellular carcinoma (HCC). However, the role of somatostatin (SST), cortistatin (CORT), neuronostatin (NST) and ghrelin systems in MAFLD-HCC progression has not yet been elucidated. We characterized the role of SST/CORT/NST and ghrelin systems in chronic liver disease and evaluated their clinical potential. The expression of the components of the SS...

Introduction: Disease-related malnutrition is one of the main factors associated with morbidity and mortality in cancer patients. Furthermore, maintaining and improving muscle mass and function are important to achieve an optimal nutritional status. In this sense, the role of leucine-enriched essential amino acids supplementation for the therapeutic approach to the promotion of muscle anabolism stands out.Methods: 46 cancer patients with malnutrition rec...

The tumor immune microenvironment is essential, it could influence a favorable or negative response against the tumor cells, and it has been related to therapy response and prognostic factors. Tumor infiltrating lymphocytes (TILs) plays an important role in the development, progression, and tumor control, thus presence of TILs could be related to disease-specific traits. The aim of the present work is to evaluate the expression of immune-related genes in forty-two pituitary ad...

Adrenocortical Carcinoma (ACC) is an aggressive malignancy with poor response to chemotherapy. Here we evaluated a potential new treatment target for ACC, focusing on the mitochondrial NADPH generator Nicotinamide Nucleotide Transhydrogenase (NNT). NNT has a central role within the mitochondrial antioxidant pathways, protecting cells from oxidative stress. Inactivating NNT mutations lead to isolated primary adrenal insufficiency, suggesting a selective vulnerability of adrenoc...

The tumor microenvironment (TME) includes diverse cellular components such as mesenchymal stem cells (MSC) and immune cells. MSC are a subset of heterogeneous cell populations characterized by the expression of CD105, CD73, and CD90 that can differentiate into chondrocytes, osteoblasts, and adipocytes in vitro. They are known to have immunomodulatory capabilities. Our aim was to isolate and characterize the immunomodulatory capabilities of MSC from pituitary tumors (P...
