    To assess the long-term outcome of patients treated with serial intrafistular injections of autologous bone marrow-derived mesenchymal stem cells (MSCs) for refractory Crohn fistulas in terms of safety and efficacy

    99mTc-68Ga-ICG-Labelled Macroaggregates and Nanocolloids of Human Serum Albumin: Synthesis Procedures of a Trimodal Imaging Agent Using Commercial Kits

    Recent developments in sentinel lymph node (SLN) and radio occult lesion localization (ROLL) highlight the need for a multimodal contrast agent, providing better presurgical PET imaging and improved intraoperative mapping thanks to fluorescence detection. For this reason, we have studied a trimodal SLN/ROLL targeting agent (99mTc-68Ga-ICG) with commercially available kits of macroaggregated or nanocolloidal albumin (MA/NC-HSA). 68Ga PET imaging does provide better spatial resolution and makes it possible to predict signal intensity during surgery. The presence of 99mTc assesses the efficacy of these compounds in vitro and also during the surgery procedure. The aim of this study was to optimise the labelling and tagging of these two radiopharmaceuticals and assess their yields and stability. Kits of MA/NC-HSA particles (Pulmocis® and NanoAlbumon®) were used for sequential radiolabelling with 99mTc and 68Ga. Fluorescent tagging was performed using indocyanine green, a tricarbocyanine dye. The ITLC radiochemical purity of the trilabelled MA/NC-HSA was >95%. Fluorescent purity was measured by scanning the strips with a PhotoDynamicEye probe. Finally, in vitro stability tests, performed with DTPA and human serum solutions, assessed the efficacy of fluorescent tagging and radiolabelling

    Commentary: \u201cMy Husband Affects Me More Than My Cancer\u201d: Reflections on Simultaneous Intimate Partner Violence and Breast Cancer Experience in a 48-Year-Old Woman'

    We present our commentary about the case of a 48-year-old woman diagnosed with early breast cancer, already presented as publication. A candidate for mastectomy, she refused immediate reconstruction. She was referred to a psycho-oncologist for further evaluation and support. Psychological sessions helped reveal a history of intimate partner violence and helped clarify the reason for her refusal to undergo immediate reconstruction and other uncommon behavior about oncological treatment and disease paths. Our experience highlights the importance of a multidisciplinary practice in which collaboration between surgeons, oncologists, and mental health professionals leads to a more in-depth understanding of the apparently paradoxical behaviors of patients, and to better care for their needs

    Autologous bone marrow-derived mesenchymal stromal cells in the treatment of fistulising Crohn's disease

    External fistulas represent a disabling manifestation of Crohn's disease with a difficult curability and a high relapse rate despite a large therapeutic armamentarium. Stem cell therapy is a novel and promising approach for treatment of chronic inflammatory conditions. We therefore investigated the feasibility, safety and efficacy of serial intrafistular injections of autologous bone marrow-derived mesenchymal stromal cells (MSCs) in the treatment of fistulising Crohn's disease
