Ethics in contemporary health care management and medical education

Rationale The health care landscape is changing: it has become the largest part of the economy and changes in public management systems will greatly affect how we practice medicine in the future. Medical education will be more important than ever to ensure patients get the best care with empathy. However, new public management systems implemented without thorough analysis might challenge medical education. An increasing number of public health care institutions provide services based on competitive market rules and express their goals in financial terms and have set financial gains as their main goal, which contradicts the fundamental nature of medical ethics and practice. Aims and objectives To explore new public management to identify potential problems and offer possible solutions for medical education and health care institutions. Methods A scoping review of the literature on public administration, hospital management, professionalism, ethics, and medical education was undertaken to map evidence on the topic and identify main concepts and knowledge gaps in the influence of management systems on the quality of medical educational practices. Results If the accelerating changes in public management are cursorily analysed, medical education may lose the esteem in which it has long been held globally. Without precautions, the so-called new public management medical faculties will-at best-generate economic benefit, following a business model with strict quality rules, regulations, standardized products, and complex analysis and measurement systems. However, these faculties will function at a level far below the ideal of teaching institutions distinguished for their outstanding components, creativity, and ambience. Conclusions Patients and teaching values are not reducible to financial terms only and the acknowledgement of non-financial values is fundamental to achieve quality in health care and education. The most essential step could be selecting managers who will implement public management principles while taking into account both business requirements and medical ethics.Scientific Assessment and Innovation in Neurosurgical Treatment Strategie

Polyethylene Glycol (PEG)-induced Mouse Model of Choroidal Neovascularization*

In this study, we describe a new method for inducing choroidal neovascularization (CNV) in C57BL/6 mice, an animal model of wet age-related macular degeneration (AMD). AMD is a disease that causes central blindness in humans. We injected PEG-8 subretinally in different doses (0.125–2 mg) to induce CNV. After PEG-8 injection, we examined CNV at several time points (days 3–42). We also used Western blotting, immunohistochemistry, and ELISA to examine the complement component C3 split products, C9, VEGF, TGF-β2, and basic FGF. As early as day 1 after treatment, we found that a single subretinal injection of 1 mg of PEG-8 increased the C3 split products and the C9, TGF-β2, and basic FGF levels in the retinal pigment epithelium-choroid tissue. By day 3 after PEG-8 injection, the intraocular activation of the complement system caused induction and progression of CNV, including new vessels penetrating the Bruch's membrane. At day 5 after PEG-8 injection, we observed a fully developed CNV and retinal degeneration. Thus, in this study, we present a new, inexpensive, and accelerated mouse model of CNV that may be useful to study AMD
