During the past years, many publications and reviews have described kidney and bone lesions observed after human chronic cadmium poisonings of food or occupational origin. In this experiment carried out in rat fed with normal diets or polydeprived of vitamin D3, calcium and proteins, with or without addition of cadmium, the bone lesions observed are as severe in all polydeprived animals, wether treated with cadmium or not.

Purpose: The positron range effect can impair PET image quality of Gallium-68 (Ga). A positron range correction (PRC) can be applied to reduce this effect. In this study, the effect of a tissue-independent PRC for Ga was investigated on patient data.

In a rapidly evolving healthcare environment, artificial intelligence (AI) is transforming diagnostic techniques and personalised medicine. This is also seen in osseous biopsies. AI applications in radiomics, histopathology, predictive modelling, biopsy navigation, and interdisciplinary communication are reshaping how bone biopsies are conducted and interpreted.

Solitary plasmacytomas are localized single tumors of monoclonal plasma cells that occur in two variants: solitary plasmacytoma of bone and extraosseous plasmacytoma. Solitary plasmacytoma of bone accounts for only 1%-2% of plasma cell lesions, and extraosseous plasmacytoma is also approximately 1%. These are both very uncommon at the skull base.

Introduction: The nasoseptal flap (NSF) has become a widely favoured choice for reconstructing skull base defects following the endoscopic endonasal approach (EEA). However, the exposed septal cartilage and bone at the donor site often require an extended duration for secondary healing. This study investigated whether the free middle turbinate (MT) mucosa grafting at the septal donor site could mitigate post-operative nasal morbidity.

This study aims to explore the relationship between the gut microbiome, serum metabolome, and FR in chronic LBP patients.
Methods: Serum metabolomic profiling and gut microbiome analysis were conducted in chronic LBP patients with and without FR (LBP + FR, = 40; LBP, = 40) and Healthy Controls (HC, = 31).
