Management of missed injuries in polytrauma patient

State University of Medicine and Pharmacy “Nicolae Testemițanu”, Republic of Moldova, Institute of Emergency Medicine, Chișinău, Republic of Moldova, Al VIII-lea Congres Naţional de Ortopedie și Traumatologie cu participare internaţională 12-14 octombrie 2016According CRICO Strategies, among the most common and costly medical errors committed in emergency departments are establishing a delay in diagnosis or misdiagnosis, which can have a tragic end for the patient. The management of multiple trauma patients presents a worldwide diagnostic and therapeutic challenge to trauma, orthopedic and general surgeons. Significant injuries can be missed during primary and secondary surveys in multiply injured patients, for whom resuscitation, diagnosis and therapy have to proceed simultaneously. Many factors involved in the initial resuscitation of the multiple trauma patients, such as altered level of consciousness, hemodynamic instability, or inexperience and inadequate diagnostic evaluation, may lead to missed injuries or a „medical errors”. The injuries can be missed at any stage of the management of the trauma patient, including intraoperatively, and may involve all regions of the body. Management of polytraumatised patient need application of primary and secondary survey protocols, as is the ATLS (Advanced Trauma Life Support) protocol, will minimize the chance of life-threatening critical medical errors. Also, intraoperative careful approach is needed for all patients, but especially for hemodynamically unstable patients, giving priority to other regions of the human body than appreciated as trauma, for the presence of vascular lesions. Examination of polytraumatised patient with special vigilance in a tertiary look, after patient returns to consciousness, will help detect missed lesions during the initial assessment. In most cases we detect missed lesions. This approach will lead to early detection of missed injuries and reduce lost their consequences

A spiking recurrent neural network with phase change memory neurons and synapses for the accelerated solution of constraint satisfaction problems

Pedretti G, Mannocci P, Hashemkhani S, et al. A spiking recurrent neural network with phase change memory neurons and synapses for the accelerated solution of constraint satisfaction problems. IEEE Journal on Exploratory Solid-State Computational Devices and Circuits. 2020;6(1):189-97.Data-intensive computing applications, such as object recognition, time series prediction, and optimization tasks, are becoming increasingly important in several fields, including smart mobility, health, and industry. Because of the large amount of data involved in the computation, the conventional von Neumann architecture suffers from excessive latency and energy consumption due to the memory bottleneck. A more efficient approach consists of in-memory computing (IMC), where computational operations are directly carried out within the data. IMC can take advantage of the rich physics of memory devices, such as their ability to store analog values to be used in matrix-vector multiplication (MVM) and their stochasticity that is highly valuable in the frame of optimization and constraint satisfaction problems (CSPs). This article presents a stochastic spiking neuron based on a phase-change memory (PCM) device for the solution of CSPs within a Hopfield recurrent neural network (RNN). In the RNN, the PCM cell is used as the integrating element of a stochastic neuron, supporting the solution of a typical CSP, namely a Sudoku puzzle in hardware. Finally, the ability to solve Sudoku puzzles using RNNs with PCM-based neurons is studied for increasing size of Sudoku puzzles by a compact simulation model, thus supporting our PCM-based RNN for data-intensive computing
