Despite significant progress regarding clinical detection/imaging evaluation modalities and genetic/molecular characterization of pathogenesis, advanced renal cell carcinoma (RCC) remains an incurable disease and overall RCC mortality has been steadily rising for decades. Concomitantly, clinical definitions have been greatly nuanced and refined. RCCs are currently viewed as a heterogeneous series of cancers, with the same anatomical origin, but fundamentally different metabolisms and clinical behaviors. Thus, RCC pathological diagnosis/subtyping guidelines have become increasingly intricate and cumbersome, routinely requiring ancillary studies, mainly immunohistochemistry. Meanwhile, RCC-associated-antigen targeted systemic therapy has been greatly diversified and emerging, novel clinical applications for RCC immunotherapy have already reported significant survival benefits, at least in the adjuvant setting. Even so, systemically disseminated RCCs still associate very poor clinical outcomes, with currently available therapeutic modalities only being able to prolong survival. In lack of a definitive cure for advanced RCCs, integration of the amounting scientific knowledge regarding RCC pathogenesis into RCC clinical management has been paramount for improving patient outcomes. The current review aims to offer an integrative perspective regarding contemporary RCC clinical definitions, proper RCC clinical work-up at initial diagnosis (semiology and multimodal imaging), RCC pathological evaluation, differential diagnosis/subtyping protocols, and novel clinical tools for RCC screening, risk stratification and therapeutic response prediction. more...

The current paper challenges convolutional neural networks to address the computationally undebated task of recognizing four key views in first trimester fetal heart scanning (the aorta, the arches, the atrioventricular flows and the crossing of the great vessels). This is the primary inspection of the heart of a future baby and an early recognition of possible problems is important for timely intervention. Frames depicting the views of interest were labeled by obstetricians and given to several deep learning architectures as a classification task against other irrelevant scan sights. A test accuracy of 95% with an F1-score ranging from 90.91% to 99.58% for the four key perspectives shows the potential in supporting heart scans even from such an early fetal age, when the heart is still quite underdeveloped . more...

The intense growth in the mobile robotics market is leading to a demand for low cost solutions concerning the robotics navigation and mapping. This paper presents a complex system made for mapping closed spaces like rooms. The entire process of developing such a system will be described, starting with the hardware parts, continuing with the algorithms that were used and finally, the actual results that were achieved. The complexity of the project consists in the fact that a large variety of knowledge from different domains was used such as: embedded systems, robotics, principles, techniques and measuring devices, data communication, cloud computing, database principles and so on. The paper will describe the usage of the distance measurement sensor, Scanse Sweep, which is using the LIDAR (light detection and ranging) technique in order to collect data which will be analysed by a software application that is running on a PC. The paper also presents features like the usage of mobile phones, usage of Cloud for data saving and manipulation, algorithms that ensure the autonomy of the robot and algorithms used for achieving a full scan of a room making as fewer moves as possible. more...

The present study compares abdominoperineal resection (APR) performed by minimally invasive and open approach, regarding preoperative selection criteria, intraoperative and early postoperative aspects, in choosing the suitable technique performed by surgical teams with experience in both open and minimally invasive surgery (MIS). Methods: This is a retrospective study, conducted between 2008-2020. Two hundred thirty-three patients with APR performed for low rectal or anal cancer were included. The cohort was divided into two groups, depending on the surgical approach used: Minimally Invasive Surgery (laparoscopic and robotic procedures) and Open Surgery (OS). The perioperative characteristics were analyzed in order to identify the optimal approach and a possible selection criteria. Results: We identified a high percentage of patients with a history of abdominal surgery in the open group (p = .0002). Intraoperative blood loss was significantly higher in the open group (p= .02), with an increased number of simultaneous resections (p = .041). The early postoperative outcome was marked by significantly lower morbidity in the MIS group (p = .005), with mortality recorded only in the open group (3 cases), in patients that associated severe comorbidities. The hystopathological results identified a significant number of patients with stage T2 in the MIS group (p= .037). Conclusions: Minimally invasive surgery provides a major advantage to APR, by avoiding an additional incision, the specimen being extracted through the perineal wound. The success of MIS APR seems to be assured by a good preoperative selection of the patients, alongside with experienced surgical teams in both open and minimally invasive rectal resections. The lack of conversion identified in robotic APR confirm the technical superiority over laparoscopic approach. more...

The automotive industry is developing continuously, trying to improve, among others, the safety of drivers, passengers, and pedestrians. Using modern technology, the dangers caused by weather hazards like rain, snow, fog, or glare were identified and reduced. This paper presents an anti-glare solution using existing technologies that can be found already in a high-end car like the driver&rsquo, s eyes tracking systems, light intensity sensors, or head-up displays. In addition to the existing elements, a sun tracking sensor is required to detect the point where the sun light has the maximum intensity on the windshield surface. Knowing the driver&rsquo, s position and the point on the windshield where the sunlight has a high intensity, a dark spot can be created on the windshield in order to reduce the discomfort created by glare. Depending on the intensity of the light and taking into consideration the traffic safety laws, the spot&rsquo, s transparency can vary between certain limits. Therefore, the dangers caused by glare will be diminished and the risks of not observing pedestrians, other traffic participants, traffic signs, or sudden curves will be considerably lower. Another advantage of using a digital sunshade based on smart glass or in-glass transparent displays, instead of a regular sunshade, is that the whole windshield can be protected against glare not just the top of it. The results were verified and highlighted using computer simulations done via a MATLAB environment. more...

Wastewater is treated in wastewater treatment plants (WWTP) through various physical, biological and chemical methods. A good control of WWTP processes could lead to better water quality and to an efficient use of energy. In order to control the treatment process all parameters need to be known. Some of them cannot be measured, so an estimate of the unknown parameters has to be used. This paper proposes the development of a linear model which will be used in future research for dynamic control design. To estimate the unknown parameters, a Luenberger observer and a Kalm an filter are implemented. more...

The aim of this study is to evaluate the amount of training needed by a trainee, with no background in microsurgery, in order to achieve proper skills for microvascular anastomosis. A protocol based on the rat femoral artery was established to provide a quantitative representation. Five inexperienced subjects started performing microvascular anastomosis. Patency was assessed at 30 min. The final assessment was performed at 2 weeks when rats were reoperated and the patency below the anastomosis was checked. The experiment was discontinued for one subject when he/she succeeded to have two series of four anastomosis with 100% patency at 2 weeks. The results were: 47.5% patency rate at 30 min and 7.5% at 2 weeks (series 1-2); 67.5 and 32.5% (3-4); 82.5 and 35% (5-6); 100 and 70% (7-8); 100 and 87.5% (9-10). Two trainees obtained 100% patency at 2 weeks after series 9-10. Other three needed two more series. There is a significant statistic difference (P < 0.01) between the results at 30 min and 2 weeks for the series (1-2, 3-4, 5-6, 7-8). The patency rate at 2 weeks reflects in a better way the microsurgical skills of a trainee. For long term functioning anastomosis, the training period needs an extension beyond that necessary for 100% patency at 30 min. more...
