Extragenital malignant mixed mesodermal müllerian tumors (MT) are rare neoplasms with poor prognosis. Most of them affect women older than 60 years. We present here a case with primary peritoneal malignant mixed müllerian tumor occurring in a young woman who underwent previous hysterectomy and double oophorectomy secondary to a benign disease. We report on the clinical, pathological, and immunohistochemical features of this lesion, which was composed of a poorly differentiated epithelial component and multiple areas of chondromatous differentiation. Along with a brief review of previously reported literature about genital and extragenital MT, some concepts relevant to this case are discussed.

Microstructure of the human metastatic vertebral body.

Department of Industrial Engineering, Alma Mater Studiorum - University of Bologna, Bologna, Italy.
Introduction: Bone spinal metastases disrupt the bone homeostasis, inducing a local imbalance in the bone formation and/or resorption, with consequent loss of the structural optimisation of the vertebrae and increase of the risk of fracture. Little is known about the microstructure of the metastatic tissue, the microstructure of the tissue surrounding the lesion, and how it does compare with vertebrae with no lesions observed on the biomedical images. A comprehensive assessment of the microstructural properties of the entire vertebral body can be obtained with micro computed tomography.

Introduction: Tertiary prevention through physical activity and psychosocial support can positively impact patient outcomes, such as physical function and quality of life (QoL). However, more research is required on the effectiveness of strategies designed to increase the uptake of tertiary prevention programmes among cancer patients. Here, we present the protocol for a single-centre, randomised controlled pilot trial testing the preliminary effectiveness of social prescription and virtual patient information in increasing tertiary prevention among cancer patients and support persons (SPs) (ESPRIT "ffectiveness of a ocial escription and virtual patient nformation in increasing ertiary prevention" pilot trial).

Background: Telehomecare monitoring (TM) in patients with cancer is a complex intervention. Research shows variations in the benefits and challenges TM brings to equitable access to care, the therapeutic relationship, self-management, and practice transformation. Further investigation into these variations factors will improve implementation processes and produce effective outcomes.

Unlabelled: Biochemical analyses of cerebrospinal fluid (CSF) are routinely performed at diagnosis in many pediatric oncology and hematology centers when acute leukemia is diagnosed. However, the clinical relevance of these analyses remains unclear. We conducted a retrospective analysis of biochemical CSF data from children diagnosed with acute leukemia at two French hospitals between 2016 and 2023 assessing the results in relation to the presence or absence of leukemic neuromeningeal involvement and the correlation between cytological and biochemical analyses.

In this study, four novels 2,5,6-trisubstituted imidazothiadiazole derivative ligands and their Ag(I) complexes were synthesized and characterized using various spectroscopic analysis techniques. First, imidazo[2,1-b][1,3,4]thiadiazole derivative (3) was obtained from the reaction of 5-amino-1,3,4-thiadiazole-2-thiol with benzyl bromide in the presence of KOH in an ethanolic medium. In the next step, the resultant compound reacted sequentially with four substituted phenacyl bromide derivatives (4a-4d) under refluxed ethanol for 24 h to obtain substituted 2-(benzylthio)-6-phenylimidazo[2,1-b][1,3,4]thiadiazole derivatives (5-8).
