    Abstract: Although the introduction of specific guidelines regarding the acute management of trauma patients have resolved many inconsistencies in the acute treatment pathways, grey areas are still preventing consensus and unitary standards of care. The treatment of splenic injuries has seen a notable shift from splenectomy only in the early 20th century to mainly non-operative contemporary approaches. However, there is no current agreement on the optimum timing of switching from conservative to operative decisions, raising the legitimate question of whether some patients are put at risk by waiting too much or other patients are deprived of a necessary organ by not waiting enough. This paper focuses on the non-operative paradigms of blunt splenic injuries and their immediate and long-term clinical implications presented as a short narrative review. It presents the historical perspective on the treatment of splenic injuries, the role of surgery and selective angioembolisation and their repercussions on the immunological functions of the spleen.

    Abstract: Increasing interest in using minimally invasive approaches in TKA has led to the question: how much deformity is accepted for using MIS in TKA? A single surgeon performed 87 consecutive TKAs with mini-subvastus approach, using unconstrained prosthesis in 84 knees and constrained prosthesis in 3 knees. We conducted a prospective study in which patients were divided into two groups according to preoperative tibiofemoral axes (TFM), one group with 160° 〈 TFM 〈 195° and the second group with 160°≥TFM≥195°. Clinical and radiographic outcomes were compared. Postoperative ROM and knee score were improved in both groups, with similar results (p 〈 0.01). Postoperative radiographic analyses showed that TFM was improved in both groups (p 〈 0.01) with the coronal alignment inferior in 160°≥TFM≥195° group than the 160° 〈 TFM 〈 195° group. The results of this study suggest that mini-subvastus approach is a proper technique to use in primary TKA in patients with a TFM angle less than 160° and more than 195° with similar results with TFM angle between 160° and 195°, and for the use of constrained prosthesis designs with promising results. Preoperative TFM angle less than 160° and greater than 195° increases the risk of component malposition in coronal plane.

    Abstract: Introduction : Several landmark studies, which enrolled heart failure (HF) patients who were ambulatory at the time of inclusion, identified iron deficiency (ID) as an important therapeutic target: intravenous iron administration with ferric carboxymaltose (FCM) improves morbidity, exercise capacity, and quality of life in patients with HF and reduced EF (HFrEF). However, there is still limited knowledge about ID prevalence during hospitalization for Worsening Chronic HF (WCHF) and about the relationship between ID during hospitalization and post-discharge outcomes. Although previous studies documented ID as an independent risk factor for poor outcomes in HFrEF, its prognostic significance in HF patients with EF 〉 40% remains unclear. Method and Results : The FERIC-RO study is a prospective, multicenter, observational study with longitudinal follow up, conducted in 9 Romanian hospitals that will include 200 consecutive patients admitted for worsening HF. A comprehensive description of the Iron metabolism biomarkers will be performed on discharge and 1-month follow up. The primary endpoint is defined as the prevalence of ID on discharge and 1-month post-discharge, and the secondary endpoints include: all-cause re-hospitalization and all-cause-mortality at 1 and 3 months follow up, and quality of life on discharge and 1-month. Conclusions : FERIC-RO will provide new evidence about the prevalence and the predictors of ID in patients hospitalized for WCHF regardless of LVEF. Furthermore, the study will explore the relationship between in-hospital ID and post-discharge outcomes. The results of FERIC-RO will thus be highly relevant to the management of patients hospitalized for AHF.

    Abstract: The aim of this paper was to review the existing described methods for measuring postoperative TKA alignment in sagittal and axial plane and to review the existing literature regarding the axial plane evaluation with the use of the computer tomography. The most frequent mistakes when positioning the total knee arthroplasty (TKA) components are done in the axial plane, so it is necessary to know what the limits of the radiographic evaluation are and, for this evaluation, the CT scan is the most valuable in assessing the rotation of the components.

    Abstract: Forming and cutting tools are subjected to the intense wear solicitations. Usually, they are either subject to superficial heat treatments or are covered with various materials with high mechanical properties. In recent years, thermal spraying is used increasingly in engineering area because of the large range of materials that can be used for the coatings. Titanium nitride is a ceramic material with high hardness which is used to cover the cutting tools increasing their lifetime. The paper presents the results obtained after deposition of titanium nitride layers by reactive plasma spraying (RPS). As deposition material was used titanium powder and as substratum was used titanium alloy (Ti6Al4V). Macroscopic and microscopic (scanning electron microscopy) images of the deposited layers and the X ray diffraction of the coatings are presented. Demonstration program with layers deposited with thickness between 68,5 and 81,4 μm has been achieved and presented.

    Abstract: WC/10Co4Cr and WC/20CrC7Ni powders were sprayed onto the surface of low-carbon steel substrates using the high velocity oxygen fuel (HVOF) spraying method. Microstructure of the obtained coatings was evaluated by scanning electron microscopy (SEM). X-ray diffraction (XRD) analysis as well as hardness and porosity testing were performed on the samples. The abrasion wear resistance of the coatings was determined using the rubber wheel abrasion test. The mass loss rate (mg/h) of the samples was measured and the test results showed that the WC-CrC-Ni coating has better abrasion wear properties than the WC-CoCr coating.

    Abstract: Artificial intelligence and robotic process automation are among the next generation of digital technologies that are transforming the workplace and our daily lives. And digital transformation has become a critical strategy for many businesses and their leadership. In today's fast-paced and ever-changing business environment, the cornerstone of organizational success is innovation. As the business environment is in perpetual modification and development, it requires businesses to be adaptive to both external and internal factors. The instability of the organizational environment increases the necessity and benefits of employee innovation. The authors analyze the extensive literature defining artificial intelligence, focusing on automation and specifically the role robotic process automation has in increasing organizational efficiency, reducing cost, and ensuring quality. In expanding on the scientific literature surrounding robotic process automation, the article analyses a case study of a Romanian tech company whose complex internal technology ecosystem has resulted in a disconnected landscape which required constant multi-system manual intervention in order to ensure process and data cohesion. The authors present the company’s response to the increased consumption of human capital on repetitive tasks that were increasingly subject to errors, in the form of robotic process automation and levels of machine learning and artificial intelligence. In following the progress of the company towards adopting robotic process automation to increase efficiency, speed, accuracy, and security of processes and tasks, the authors identify the benefits of directing human labor towards more meaningful activities and allowing the repetitive tasks to be shifted to robotic labor. The authors followed the progress of a service technology solutions organization that has established an IT intelligent operation ecosystem, with new strategies across various key departments such as finance, human resources, and Internal Audit, followed by their leadership perspective and thinking for the company's next steps in this case study.

    Abstract: Pathological fractures occur in an area of bone where either the quantity or quality of bone is modified and the main cause of bone metastases that weaken the structure and will lead to fractures are in high proportion given by visceral tumors or primary hematopoietic tumors like myeloma. This paper’s objective was to review the actual knowledge in the treatment of fractures secondary to metastases. Spinal lesions were not discussed in this paper. Literature search was performed using MEDLINE and Web of Science to find literature relevant to fracture risk and prophylactic intervention in metastatic bone disease. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline was used for this review. As results, we identified 30 papers that were suitable for this review. Most of them concluded that it is difficult to assess the amount of bone involvement on radiographs alone. Using the actual guidelines for prophylactic fixation may result in an under treatment or overtreatment of patients with metastatic bone disease. Their ability to determine which metastatic bone lesions will fracture is altered mainly because of the small number of patients included in the studies. The prediction factors for fracture risk are still to be evaluated. CT, FDG-PET or CT scan-based finite element analysis may be useful tools for the identification of impending pathological fractures requiring prophylactic stabilization.
