Abstract
Modified theranostic liposomes were created by combining phospholipid 1,2-dipalmitoyl-sn-3-glycerol-phosphatidylcholine with two previously modified Pluronic® copolymers covalently linked with spermine and folic acid to carry and stabilize the photosensitizer compound hypericin. After physicochemical characterization, the photocytotoxicity was evaluated against different cancer and healthy cells presenting a strong photodynamic effect. The formulation exhibited no photoactivity without illumination and without hypericin. In vivo, pharmacokinetics biodistribution examined the uptake and theranostic potential of this nanoformulation after its intravenous administration in animal models. Fluorescence images revealed the maximum fluorescence between 0.5-4 h post-tail vein injection, making it an appropriate period for photodynamic treatment. The fluorescence of the entire body was monitored for at least 3 days, indicating that the theranostic procedures can be performed within the 0.5-4 h range after administration, after which the intensity decreases, indicating a potent metabolic ability with no significant side effects. The fluorescence images of the main organs consistently showed a signal during the 1st day of its application. After 48 h, only residues of the modified theranostic formulation were detected in the lungs and thyroid. The promising pharmacokinetics observed in our preliminary studies highlight the potential of this system, making it a worthy candidate for further investigation with tumor models.

Toxicol Res (Camb) 2023; 12:702-708. [PMID: 37663811 PMCID: PMC10470367 DOI: 10.1093/toxres/tfad060] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 07/05/2023] [Accepted: 07/07/2023] [Indexed: 09/05/2023] Open
Abstract
Metformin exerts its anticancer effect through two mechanisms, directly affecting the tumor and indirectly reducing systemic insulin levels. The anticancer effects of aspirin occur by inhibiting Cyclooxygenase (COX)-2. COX-2 is absent in many cell types under normal conditions and increases under pathological conditions such as cancer. This study aims to investigate the effect of metformin and aspirin and their combination of them on A549 and PC3 cell lines. Metformin and aspirin were investigated separately and in combination on two cancer cell lines, A549 and PC3. The examined groups include the negative control of untreated cells and the positive control of cisplatin and drugs at concentrations of 15, 10, and 20 μg/ mL to investigate the mechanism of oxidative stress factors (reactive oxygen species, lipid peroxidation, Glutathione (GSH)) and apoptosis (lactate dehydrogenase). The results showed that aspirin, metformin, and their combination could affect cancer cell growth by damaging mitochondria, releasing reactive oxygen species, and activating the oxidative stress pathway. Also, these two drugs show the activation of the apoptotic pathway in cancer cells by increasing the lactate dehydrogenase factor and releasing it from the cells. By disrupting the balance of oxidants and antioxidants in the cell, metformin and aspirin cause an increase in the level of reactive oxygen species and a decrease in the level of glutathione reserves, followed by an increase in the level of lipid peroxidation and a decrease in cell viability. Unlike common chemotherapy drugs, these drugs have no known severe side effects; Therefore, in the not-so-distant future, these drugs can also be used as anticancer drugs. Highlights Metformin and aspirin, commonly used drugs for diabetes and inflammation, inhibit the growth of cancer cell lines, A549 and PC3.Metformin and aspirin, either separately or in combination, can potentially impede cancer cell growth by disrupting mitochondrial function, inducing the release of reactive oxygen species (ROS), and activating oxidative stress pathways.Furthermore, these drugs can trigger apoptosis, a programmed cell death mechanism, in cancer cells by increasing lactate dehydrogenase (LDH) levels and facilitating its release from the cells.

Abstract
Increasing efficiency and reducing risk in radiotherapy cancer treatment is of high importance. User assistance systems within a digitally connected radiotherapy environment can support all involved professionals to perform their individual tasks faster and better. This paper presents a qualitative analysis of radiotherapy workflows and a corresponding process modelling in order to identify hypothetical user assistance systems for specific process activities. In addition, the results of an empirical study on the identified systems are presented together with derived requirements and design principles for these systems. A structured online survey with 50 medical physicists in Germany has been conducted. Among others the acceptance, the increase of perceived efficiency and the risk reduction while using the assistance systems are analysed and discussed. The results support the creation of value adding user assistance systems for radiotherapy that improve efficiency, reduce treatment risks and reach high user acceptance levels.

Abstract
The diverse behavior of nanogold in the therapeutic field is related to its unique size and shape. Nanogold offers improvements in modern diagnostic and therapeutic implications, increases disease specificity and targeted drug delivery, and is relatively economical compared with other chemotherapeutic protocols. The diagnosis of cancer and photothermal therapy improve drastically with the implementation of nanotechnology. Different types of nanoparticles, that is, gold silica nanoshells, nanorods and nanospheres of diverse shapes and geometries, are used widely in the photothermal therapy of cancerous cells and nodules. Numerous reviews have been published on the therapeutic applications of gold nanoparticles, but studies on combinatorial applications of nanogold in cancer therapy are limited. This review focuses on the combinatorial cancer therapy using optical properties of nanogold with different shapes and geometries, and their therapeutic applications in cancer diagnosis, photothermal therapy, cancer imaging and targeted drug delivery.

Abstract
Medical devices are indispensable for cancer management across the entire cancer care continuum, yet many existing medical interventions are not equally accessible to the global population, contributing to disparate mortality rates between countries with different income levels. Improved access to priority medical technologies is required to implement universal health coverage and deliver high-quality cancer care. However, the selection of appropriate medical devices at all income and hospital levels has been difficult because of the extremely large number of devices needed for the full spectrum of cancer care; the wide variety of options within the medical device sector, ranging from small inexpensive disposable devices to sophisticated diagnostic imaging and treatment units; and insufficient in-country expertise, in many countries, to prioritise cancer interventions and to determine associated technologies. In this Policy Review, we describe the methods, process, and outcome of a WHO initiative to define a list of priority medical devices for cancer management. The methods, approved by the WHO Guidelines Review Committee, can be used as a model approach for future endeavours to define and select medical devices for disease management. The resulting list provides ready-to-use guidance for the selection of devices to establish, maintain, and operate necessary clinical units within the continuum of care for six cancer types, with the goal of promoting efficient resource allocation and increasing access to priority medical devices, particularly in low-income and middle-income countries.

Abstract
PURPOSE OF REVIEW Most information about priority setting comes from developed countries. In low-resource settings, many factors should be considered to select the best candidate for the treatments that are available. The physician is always under pressure to obtain better results in spite of the lower quantity of resources. This exposes physicians to daily ethical dilemmas and increases their anxiety and burnout. RECENT FINDINGS Most low-resource settings have restrictions in major treatments, and the number of specialized centers that have all the services is low. The surgeon has to navigate through the system as a patient advocate, taking the responsibilities of other health system actors, has to 'negotiate' to design a treatment based on outdated results or to wait for new results and has to decide whether to start or to wait for other treatments to be ready to comply with protocol recommendations. SUMMARY The surgeons face the dilemma of offering the best treatment with scarce resources but with a higher possibility of completion. Finally, we must do the best we can with what we have.
