BACKGROUND: The emergence of transoral robotic surgery (TORS) ignited the debate between surgical and nonsurgical strategies on oropharyngeal squamous cell carcinoma (SCC) management; a question further complicated by human papillomavirus (HPV). We evaluated the survival by treatment strategy independently in HPV-related and HPV-nonrelated oropharyngeal SCC. METHODS: The National Cancer Database was queried for patients with oropharyngeal SCC with known HPV status who underwent primary TORS or primary radiotherapy...

BACKGROUND: In order to improve the surgical treatment of rectal cancer, robot-assisted laparoscopy has been introduced. The robot has gained widespread use; however, the scientific basis for treatment of rectal cancer is still unclear. The aim of this study was to investigate whether robot-assisted laparoscopic rectal resection cause less perioperative pain than standard laparoscopic resection measured by the numerical rating scale (NRS score) as well as morphine consumption. METHODS: Fifty-one patients were randomized to either laparoscopic or robot-assisted rectal resection at the Department of Surgery at Aarhus University Hospital in Denmark...

Reinforcement learning (RL) enables robots to learn its optimal behavioral strategy in dynamic environments based on feedback. Explicit human feedback during robot RL is advantageous, since an explicit reward function can be easily adapted. However, it is very demanding and tiresome for a human to continuously and explicitly generate feedback. Therefore, the development of implicit approaches is of high relevance. In this paper, we used an error-related potential (ErrP), an event-related activity in the human electroencephalogram (EEG), as an intrinsically generated implicit feedback (rewards) for RL...

Flexible piezoresistive sensors have huge potential for health-monitoring, human-machine interfaces, prosthetic limbs and intelligent robotics. A variety of nanomaterials and structural schemes have been proposed for realizing ultrasensitive flexible piezoresistive sensors. However, despite success of recent efforts, the high sensitivity within narrower pressure ranges and/or the challenging adhesion and stability issues still potentially limit their broad applications. Herein, we introduce a biomaterial-based scheme for the development of flexible pressure sensors that are ultrasensitive (resistance change by five orders) over broad pressure ranges of 0...

A robust strategy for the automated preparation of aqueous two-phase systems (ATPS) using a liquid handling sample processor was developed using gravimetric methods: to determine the accuracy of preparation. The major robotic control parameters requiring adjustment were; speed of aspiration and dispense; delay times following aspiration and dispense alongside measures to control cross-contamination during phase sampling. In general mixture compositions of both polymer/polymer and polymer/salt mixtures could be prepared with a target bias accuracy of less than 5%...

In this work, a novel robotic arm driven by sandwich piezoelectric transducers is proposed. The proposed robotic arm is composed of three arms and four joints. Each arm consists of a sandwich piezoelectric transducer and an H-shaped hollow frame. The sandwich piezoelectric transducer utilizes frictional force to drive the joints on its both sides to rotate simultaneously. The joint between two arms can be driven to rotate in two perpendicular directions by two sandwich piezoelectric transducers. The rotation of joints results in the arm motion...

Motivation: Correct and rapid determination of Mycobacterium tuberculosis (MTB) resistance against available tuberculosis (TB) drugs is essential for the control and management of TB. Conventional molecular diagnostic test assumes that the presence of any well-studied single nucleotide polymorphisms is sufficient to cause resistance, which yields low sensitivity for resistance classification. Methods: Given the availability of DNA sequencing data from MTB, we developed machine learning models for a cohort of 1839 UK bacterial isolates to classify MTB resistance against eight anti-TB drugs (isoniazid, rifampicin, ethambutol, pyrazinamide, ciprofloxacin, moxifloxacin, ofloxacin, streptomycin) and to classify multi-drug resistance...

While the 'best pancreatic anastomosis technique' debate is going during Whipple procedure, the laparoscopic pancreaticoduodenectomy lately began to appear more and more often in the medical literature. All the popular anastomosis techniques used in open pancreas surgery are being experienced in laparoscopic pancreaticoduodenectomy. However, when they were adapted to laparoscopy, their implementation was not technically easy, and assistance of robotic surgery was sometimes required at the pancreatic anastomosis stage of the procedure...
