ABSTRACT During the past five years, transaxillary approaches to thyroid surgery have been introduced into surgical literature. These techniques were initially performed using traditional endoscopy, and most recently with a surgical robot. This manuscript describes our approach to robotassisted transaxillary surgery (RATS) for thyroidectomy using a single axillary incision. Because of the steep learning curve, this procedure is best implemented with a team approach. The ideal team consists of a console surgeon who operates the robot, a bedside surgeon who assists with retraction and troubleshoots robotic arm collisions and a circulating assistant who helps optimize the efficiency of the operation.

The Way

This chapter examines the advent of the neuromarketing revolution, which over the past 10 years changed the way market research is conducted worldwide to include nonconscious measures in everyday studies. It required a form of technology transformation as traditional researchers and marketers came to accept that nonconscious response and emotion are critical in driving brand perceptions and behaviors. Moreover, it demanded a steep learning curve for understanding and adopting new types of scientifically driven methodologies such as EEG and Biometrics. Now with experience and extensive research by academics and practitioners, neurometrics are considered of high value for understanding consumer response and of great potential value for improving prediction leveraging AI and machine learning.

Over the past few years, the U.S. nuclear power industry has gained substantial experience and appreciation of the technical complexity and rigor required to meet a performance-based site clean-up standard. Five large power reactors and several smaller ones are now well along the path to license termination. They have not been on this journey alone. There has been a steep learning curve for all stakeholders involved in the process including state and federal radiation regulators, legislators, and the public. We have all learned that the translation of results from a post remediation survey interpreted through pathway modeling for comparison with a dose-based clean-up standard is for many a leap of faith. Our regulator has an understandable desire to address this uncertainty by demanding conservative analysis at each turn. As a result, it is extremely demanding to demonstrate that a clean-up standard in the 0.15–0.25 mSv/a range has been met. It is not likely that a standard in the 10 μSv/a level, typically associated with radiological clearance standards, can be practically demonstrated while still meeting the current expectations of U.S. Nuclear Regulatory Commission for technical rigor.

The Ideal

This book lays out a vision for how we should theorize about justice in a diverse society. It shows how free and equal people, faced with intractable struggles and irreconcilable conflicts, might share a common moral life shaped by a just framework. The book argues that if we are to take diversity seriously and if moral inquiry is sincere about shaping the world, then the pursuit of idealized and perfect theories of justice—essentially, the entire production of theories of justice that has dominated political philosophy for the past forty years—needs to change. Drawing on recent work in social science and philosophy, the book points to an important paradox: only those in a heterogeneous society—with its various religious, moral, and political perspectives—have a reasonable hope of understanding what an ideally just society would be like. However, due to its very nature, this world could never be collectively devoted to any single ideal. The book defends the moral constitution of this pluralistic, open society, where the very clash and disagreement of ideals spurs all to better understand what their personal ideals of justice happen to be. Presenting an original framework for how we should think about morality, this book rigorously analyzes a theory of ideal justice more suitable for contemporary times.

The Ideal

‘No person can be blamed for refusing to read another word of what promises to be a mere imposition upon his credulity.’ Julian West, a feckless aristocrat living in fin-de-siècle Boston, plunges into a deep hypnotic sleep in 1887 and wakes up in the year 2000. America has been turned into a rigorously centralized democratic society in which everything is controlled by a humane and efficient state. In little more than a hundred years the horrors of nineteenth-century capitalism have been all but forgotten. The squalid slums of Boston have been replaced by broad streets, and technological inventions have transformed people’s everyday lives. Exiled from the past, West excitedly settles into the ideal society of the future, while still fearing that he has dreamt up his experiences as a time traveller. Edward Bellamy’s Looking Backward (1888) is a thunderous indictment of industrial capitalism and a resplendent vision of life in a socialist utopia. Matthew Beaumont’s lively edition explores the political and psychological peculiarities of this celebrated utopian fiction.

AbstractAccess to systems for robot-assisted surgery is limited due to high costs. To enable widespread use, numerous issues have to be addressed to improve and/or simplify their components. Current systems commonly use universal linkage-based input devices, and only a few applicationoriented and specialized designs are used. A versatile virtual reality controller is proposed as an alternative input device for the control of a seven degree of freedom articulated robotic arm. The real-time capabilities of the setup, replicating a system for robot-assisted teleoperated surgery, are investigated to assess suitability. Image-based assessment showed a considerable system latency of 81.7 ± 27.7 ms. However, due to its versatility, the virtual reality controller is a promising alternative to current input devices for research around medical telemanipulation systems.

AbstractThis systematic review and meta-analysis were conducted to compare the accuracy of component positioning, alignment and balancing techniques employed, patient-reported outcomes, and complications of robotic-arm assisted total knee arthroplasty (RATKA) with manual TKA (mTKA) and the associated learning curve. Searches of PubMed, Medline and Google Scholar were performed in October 2020 using PRISMA guidelines. Search terms included “robotic”, “knee” and “arthroplasty”. The criteria for inclusion were published clinical research articles reporting the learning curve for RATKA and those comparing the component position accuracy, alignment and balancing techniques, functional outcomes, or complications with mTKA. There were 198 articles identified, following full text screening, 16 studies satisfied the inclusion criteria and reported the learning curve of rTKA (n=5), component positioning accuracy (n=6), alignment and balancing techniques (n=7), functional outcomes (n=7), or complications (n=5). Two studies reported the learning curve using CUSUM analysis to establish an inflexion point for proficiency which ranged from 7 to 11 cases and there was no learning curve for component positioning accuracy. The meta-analysis showed a significantly lower difference between planned component position and implanted component position, and the spread was narrower for RATKA compared with the mTKA group (Femur coronal: mean 1.31, 95% confidence interval (CI) 1.08–1.55, p<0.00001; Tibia coronal: mean 1.56, 95% CI 1.32–1.81, p<0.00001). Three studies reported using different alignment and balancing techniques between mTKA and RATKA, two studies used the same for both group and two studies did not state the methods used in their RATKA groups. RATKA resulted in better Knee Society Score compared to mTKA in the short-to-mid-term follow up (95%CI [− 1.23,  − 0.51], p=0.004). There was no difference in arthrofibrosis, superficial and deep infection, wound dehiscence, or overall complication rates. RATKA demonstrated improved accuracy of component positioning and patient-reported outcomes. The learning curve of RATKA for operating time was between 7 and 11 cases. Future well-powered studies on RATKAs should report on the knee alignment and balancing techniques utilised to enable better comparisons on which techniques maximise patient outcomes.Level of evidence III.

AbstractSingle-incision laparoscopic surgery (SILS) has the potential to improve perioperative outcomes, including less postoperative pain, shorter operation time, less blood loss, and shorter hospital stay. However, SILS is technically difficult and needs a longer learning curve. Between April 2016 and September 2019, a total of 198 patients with clinical stage I/II right colon cancer underwent curative resection. In the case of the SILS approach, an organ retractor was usually used to overcome SILS-specific restrictions. The patients were divided into two groups by surgical approach: the SILS with organ retractor group (SILS-O, n = 33) and the conventional laparoscopic surgery group (LAC, n = 165). Clinical T status was significantly higher in the LAC group (p = 0.016). Operation time was shorter and blood loss was lower in the SILS-O group compared to the LAC group (117 vs. 197 min, p = 0.027; 10 vs. 25 mL, p = 0.024, respectively). In the SILS-O group, surgical outcomes including operation time, blood loss, number of retrieved lymph nodes, and postoperative complications were not significantly different between those performed by experts and by non-experts. Longer operation time (p = 0.041) was significantly associated with complications on univariate and multivariate analyses (odds ratio 2.514, 95%CI 1.047–6.035, p = 0.039). SILS-O was safe and feasible for right colon cancer. There is a potential to shorten the learning curve of SILS using an organ retractor.
