Survival and Stage in Lung Cancer

Purpose: Lung cancer is the leading cause of cancer death worldwide. Although the 5-year survival rates of for non-small cell lung carcinoma (NSCLC) ranges from 20% to 70%. The present study investigates the rates of early recurrence in a total of 83 patients operated for NSCLC and presents the related findings in reference to the data available in the literature. Materials and Methods: Patients who underwent lung resection for malignancy between March 2019 and September 2021 were retrospectively examined. The patient data, including age, gender, presence of preoperative chemotherapy administration, opera-tions performed, operation dates, pathology results, postoperative staging, survival, and relapses, were documented. Results: A total of 83 patients who underwent lung resection for malignancy between March 2019 and September 2021 were examined. The patients had a median age of 62 years. Of the total number of patients four patients developed recurrence and 79 continued their follow-up without any recurrence. Of the patients who underwent lung resection, eight (9.6%) patients died within the first postoperative 2-year period. The mean survival period of these eight patients was 14.6 months (7–20 months). Conclusion: Although various parameters, such as age, gender, pathological type, and location of the tumor are examined and compared, according to the available data on the long-term survival of surgical patients, it is known that the only parameter that affects survival is the pathological stage of the patient

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Control system design for autonomous formation flight Otonom kol uçuşu için kontrol sistemi tasarimi

© 2021 IEEE.Recently swarm technology has provided new opportunities especially for aerial vehicle operations. Many missions have to be accomplished by pilots could be completed autonomously. However, autonomy of cooperated aerial vehicles consists of important complexities in control systems. The main purpose of this study is to design required autopilots for autonomous formation flight. For that, a leader and a follower aircraft are considered. A fully autonomous control system that provides the follower aircraft to track the leader aircraft is designed. Trajectory tracking is accomplished by a new geometric algorithm under effect of vortex caused by leader aircraft. The designed system controls formation flight autonomously

Vision-Based Autonomous Aerial Refueling

© 2022, American Institute of Aeronautics and Astronautics Inc. All rights reserved.Aerial refueling tasks are very challenging due to the high risk of aircraft close proximity. Currently, within the drogue-probe method, the receiver aircraft pilot manages the refueling task in accordance with the tanker aircraft pilot. Therefore, autonomous aerial refueling is still an unaccomplished task for aircrafts. In this paper, a fully automated aerial refueling procedure based on digital visual inspection is proposed. A nonlinear dynamic model of receiver aircraft is derived to track the motion of drogue. In order to control the receiver aircraft affected by tanker aircraft vortex during approach, and ensure the receiver aircraft to automatically track and dock the tanker aircraft, an autopilot system that considers visual sensing of drogue motion is designed. The receiver aircraft is controlled by the autopilot system via translational motion of tanker aircraft projected by a camera mounted on the receiver aircraft. Thanks to this vision-based controllers, the need of tanker aircraft positioning is denied since camera projection has the capability of perception of three-dimensional direction of tanker aircraft. In order to test the autopilots include vision-based controllers and algorithms, the vision-based autonomous aerial refueling is operated under presence of turbulence and vortex. Finally, the simulation results demonstrate that the proposed guidance-navigation-control system achieve aerial refueling autonomously, and make it feasible and realizable for aircrafts

In the title solvated compound, C28H19N2O4 center dot C2H6OS, the central beta-lactam ring is almost planar (r.m.s. deviation = 0.002 angstrom). It makes dihedral angles of 1.92 (11), 83.23 (12) and 74.90 (10)degrees with the methoxy-and chlorophenyl rings and the ring plane of the 1H-benzo[de]isoquinoline-1,3(2H)-dione group [maximum deviation = 0.089 (1)], respectively. An intramolecular C-H center dot center dot center dot O hydrogen bond closes an S(6) ring and helps to establish the near coplanarity of the beta-lactam and methoxybenzene rings. In the crystal, the components are linked by C-H center dot center dot center dot O hydrogen bonds, C-H center dot center dot center dot pi interactions and aromatic pi-pi stacking interactions [centroid-to-centroid distances = 3.6166 (10) and 3.7159 (10) angstrom], resulting in a three-dimensional network, The dimethyl sulfoxide solvent molecule is disordered over two sets of sites in a 0.847 (2):0.153 (2) ratio

A region of disordered electron density, probably disordered solvent molecules, was treated with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18], which indicated a solvent cavity of 322 angstrom(3) containing approximately 91 electrons. Their formula mass and unit-cell characteristics were not taken into account during the refinement

Retroperitoneal Paraganglioma: A Case Report

Retroperitoneal paragangliomas are rare neuroendocrine tumors of neural crest origin. They are mostly benign, however; malignant tumors may present aggressive behavior and may lead to metastasis. Complete surgical resection of the mass is the only potential curative treatment modality for retroperitoneal paragangliomas. Postsurgical follow-up is important for malignant potential. Here we report a case of a 18 year-old female with an 8.5 cm mass located anterior of the right kidney, treated by complete surgical excision
