Preoperative anaemia is an independent risk factor for an increase in perioperative morbidity and mortality. Patient Blood Management (PBM) aims for an early detection of anaemia in elective surgery patients. Reasons for anaemia should be detected and causally treated if possible. A multidisciplinary team of specialists aims for diagnosis and causative treatment of easily treatable and frequent causes of anaemia like iron deficiency, bleeding or (autoimmune) haemolysis using patients' specific history, examination, laboratory and technical methods. Such an outpatient PBM programme is only feasible, if anaesthesiologists, surgeons, haematologists, gastroenterologists, gynecologists, laboratory and transfusion medicine specialists work together in a PBM team using a common PBM plan. Communication within this team as well as with the patients' physicians in their private offices is key for a long lasting success of such a PBM programme.

Light buckets and laser beams: mechanisms and applications of photobiomodulation (PBM) therapy.

Photobiomodulation (PBM) therapy, a non-thermal light therapy using nonionizing light sources, has shown therapeutic potential across diverse biological processes, including aging and age-associated diseases. In 2023, scientists from the National Institute on Aging (NIA) Intramural and Extramural programs convened a workshop on the topic of PBM to discuss various proposed mechanisms of PBM action, including the stimulation of mitochondrial cytochrome C oxidase, modulation of cell membrane transporters and receptors, and the activation of transforming growth factor-β1. They also reviewed potential therapeutic applications of PBM across a range of conditions, including cardiovascular disease, retinal disease, Parkinson's disease, and cognitive impairment.

Purpose: Oral lichen planus (OLP) is a chronic inflammatory disease, in which T-Lymphocytes induce apoptosis of basal keratinocytes, leading to the formation of symptomatic lesions. It is assumed that blocking the cell death program and enhancing cell proliferation would be crucial to the healing process. The aim of the study was to verify the efficacy of Photobiomodulation (PBM) in OLP management, by evaluating the effects of laser irradiation on the processes of apoptosis and cell proliferation.

The effects of T cell differentiation arising from immune checkpoint inhibition targeting cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and programmed cell death protein 1 (PD-1) on the immunological memory response remain unclear. Our investigation into the effects of anti-CTLA-4 and anti-PD-1 on memory T cell formation in mice reveals that memory T cells generated by anti-CTLA-4 exhibit greater expansion, cytokine production, and antitumor activity than those from anti-PD-1. Notably, anti-CTLA-4 preserves more T cell factor-1 (TCF-1)+ T cells during priming, while anti-PD-1 leads to more thymocyte selection-associated high mobility group box (TOX)+ T cells.

Periodontitis, an oral disease initiated by a dysbiotic dental biofilm, has an unclear response to photobiomodulation (PBM) as an adjunctive treatment. This study investigates the effects of PBM on reactive oxygen species (ROS), apoptosis, oxidative stress, and inflammatory markers in a periodontitis model using C57BL/6 mice, divided into four groups: control (C), control + PBM (C + PBM), periodontitis (P), and periodontitis + PBM (P + PBM).

The evolution of blood saving programs to Patient Blood Management (PBM) represents a broader and more comprehensive approach to optimize the use of the patient's own blood, thus improving clinical outcomes and minimizing the risks associated with allogeneic blood transfusion with a holistic view of socio-economic sustainability. Implementing the strategies of the three PBM pillars in any hospital center involves a transversal change throughout the organization in which it can be very useful to apply the strategy defined by Kotter at the business level for change management. The support of renowned institutions such as the World Health Organization and the European Commission demonstrates the importance and urgency of implementing PBM programs, setting guidelines at an international level and supporting the adoption of effective strategies in the management of blood transfusion at a national and institutional level.
