Purpose: Due to the high prevalence of iron deficiency anemia in women undergoing gynecological surgeries and its association with worse postoperative results, it is necessary to identify and treat anemia preoperatively. However, although anemia and iron deficiency are significant global health problems, there are still disparities in the recognition and implementation of “Patient Blood Management” (PBM) as a comprehensive approach to mitigating the risks associated with these diseases. The purpose of the study is to review best practices for the treatment of anemia based on the Enhanced Recovery After Surgery (ERAS) protocol and PBM recommendations. Methods: This study reviewed the literature on preoperative iron deficiency anemia in patients undergoing gynecological surgery. We identified references through searches in PubMed using relevant search terms. Results: Among the various strategies used in PBM, perhaps the most important is the early detection and management of anemia. In gynecological surgery, there are several approaches to reducing perioperative blood loss, highlighting the use of gonadotropin-releasing hormone (GnRH) agonists (aGnRh) and antifibrinolytics. Oral and intravenous iron supplementation can be performed in addition to blood transfusion to treat anemia. Conclusion: Addressing preoperative and postoperative anemia through systematic correction, following the guidelines of the ERAS protocol and PBM guidelines, is essential to improving perioperative outcomes in women undergoing gynecological surgery.

This paper aims at presenting an application developed in Java for optimizing the design of centralized solar water heating systems with forced circulation, based on the f-chart method. The program uses data from the Brazilian Solar Atlas, performance data of flat plate collectors and thermal reservoirs from the standardized tests run within the Brazilian Labeling Program, and values of water consumption of appliances defined by the ABNT. The program finds the inclination of the collector that maximizes the annual solar fraction, or for the winter, and enables the use of arrays in series and parallel collectors. From the investment costs and O ＆ M （operations and maintenance） of solar heating systems, the program carries out economical analysis using classical parameters as net present value, discounted payback and internal rate of return. The program was validated through examples from the book of Duffle ＆ Beckman and also by comparison with the results from a project developed at UFRGS, having obtained good agreement.
