The recent results of the study evaluating the impact of macrophage transplantation in cirrhosis with the aim of improving liver function open up a number of prospects. Although negative, fewer deaths were observed, as well as a favourable cytokine profile. This is in line with other results obtained in liver disease, notably through signalling and regeneration studies on human liver tissue. For the future, a number of questions need to be answered if we are to make progress in this fascinating field.

Radiological accidents/incidents are common with nearly 400 reported since 1944 exposing about 3000 people to substantial doses of ionizing radiations with 127 deaths. Damage to hematopoietic stem and progenitor cells with resulting bone marrow failure is a common consequence of exposure to whole body acute high-dose and -dose-rate ionizing radiations and is termed hematopoietic-acute radiation syndrome, or H-ARS. Therapy of H-ARS includes transfusions, anti-bacterial and -viral drugs, molecularly-cloned hematopoietic growth factors and hematopoietic cell transplants.

Background: Anti-human epidermal growth factor receptor 2 (HER2) IgG1-based antibody therapies significantly improve cancer prognosis, yet intrinsic or acquired resistance to fragment antigen-binding (Fab)-mediated direct effects commonly occurs. Most resistant tumors retain antigen expression and therefore remain potentially targetable with anti-HER2 therapies that promote immune-mediated responses. Tumor-antigen-specific IgE class antibodies can mediate powerful immune cell-mediated effects against different cancers and have been shown to activate IgE Fc receptor-expressing monocytes.

The development of antibiotic resistance and inadequate immune response in chronic inflammation pose significant challenges in treating chronic osteomyelitis. As accepted non-antibiotic antimicrobial therapies, sonodynamic therapy (SDT) and photothermal therapy (PTT) are recognized for their effectiveness in eliminating bacteria and promoting tissue repair, rendering them promising therapeutic strategies for treating bacterial infections and preventing the emergence of drug-resistant bacteria. However, the antimicrobial action and efficacy in promoting tissue repair depend on the activation status of the host immune system.

Objectives: To compare explanted polypropylene mesh from those with and without mesh complications to determine the pathogenesis of the complications.
Methods: Between August 2019 and July 2020 66 participants attending Wesley and Royal Brisbane and Women's Hospital Urogynecology department with mesh complications and 15 undergoing repeat prolapse and/or continence surgery after prior polypropylene mesh implantation were included.
