Compression stockings reduce occupational leg swelling.

Abstract: Background. Evening edema of the legs is a physiologic phenomenon occurring after sitting and standing. Objective. The objective of this study was to investigate which compression pressure is necessary to prevent leg swelling. Methods. In 12 volunteers, the volume of both lower legs was measured in the morning and 7 h later, the difference being defined as evening edema (mL). The procedure was carried out for 4 days, in which the subjects wore below-knee stockings of different compression levels alternatively on one leg only in a random order. Compression pressure was assessed using the HATRA device. Results. The average evening edema of the noncompressed legs was 62.4 mL on the left side and 94.4 mL on the right side (n.s.). Evening edema was significantly reduced to 40.3 mL by light support stockings, to −34.1 mL by compression class A, to −39.6 by compression class I, and to −59.1 mL by compression class II. Mainly stockings exerting a pressure above 10 mmHg improved subjective symptoms. Conclusion. Calf-length compression stockings with a pressure range between 11 and 21 mmHg are able to reduce or totally prevent evening edema and may therefore be recommended for people with a profession connected with long periods of sitting or standing.

An Edge Computing Based Smart Healthcare Framework for Resource Management.

Abstract: The revolution in information technologies, and the spread of the Internet of Things (IoT) and smart city industrial systems, have fostered widespread use of smart systems. As a complex, 24/7 service, healthcare requires efficient and reliable follow-up on daily operations, service and resources. Cloud and edge computing are essential for smart and efficient healthcare systems in smart cities. Emergency departments (ED) are real-time systems with complex dynamic behavior, and they require tailored techniques to model, simulate and optimize system resources and service flow. ED issues are mainly due to resource shortage and resource assignment efficiency. In this paper, we propose a resource preservation net (RPN) framework using Petri net, integrated with custom cloud and edge computing suitable for ED systems. The proposed framework is designed to model non-consumable resources and is theoretically described and validated. RPN is applicable to a real-life scenario where key performance indicators such as patient length of stay (LoS), resource utilization rate and average patient waiting time are modeled and optimized. As the system must be reliable, efficient and secure, the use of cloud and edge computing is critical. The proposed framework is simulated, which highlights significant improvements in LoS, resource utilization and patient waiting time.
