Accurate identification of the material properties of the plantar soft tissue is important for computer-aided analysis of foot pathologies and design of therapeutic footwear interventions based on subject-specific models of the foot. However, parameter identification of the hyperelastic material properties of plantar soft tissues usually requires an inverse finite element analysis due to the lack of a practical contact model of the indentation test. In the present study, we derive an analytical contact model of a spherical indentation test in order to directly estimate the material properties of the plantar soft tissue...

Open ureterolithotomy and pyelolithotomy used to be first line therapy for treating kidney and ureteral stones. With the advent of shockwave lithotripsy, open stone surgery became less prevalent, but once ureteroscopy became more prevalent, open stone surgery became all but extinct. Advances in smaller, more flexible endoscopes and improvements in intracorporeal lithotripters, ureteroscopy has become a mainstay of therapy for kidney stones. The holmium:YAG laser can be utilized through flexible instruments and fragments any stone no matter what it is composed of...

INTRODUCTION: The holmium laser has revolutionized the practice of minimally invasive endoscopy for kidney stones. Recently, a novel, rigid hand-piece for use in percutaneous nephrolithotomy (PCNL) that couples the holmium laser with suction has been developed. To date, there exists limited data regarding the usability and ergonomics of such treatment systems. We thus sought to compare surgeon-rated usability with three different suction laser hand-pieces in a porcine model. METHODS: We performed bilateral reverse PCNL on 4 female domestic farm pigs...

INTRODUCTION: Minimally invasive laparoscopic and robotic techniques for ventral hernia repair have evolved to achieve the benefits and minimize the limitations of both the open Rives-Stoppa sublay mesh repair and laparoscopic intraperitoneal onlay mesh (IPOM) repair. By combining the principles of a retromuscular repair with the benefits of a minimally invasive approach, these techniques attempt to decrease recurrence, increase functionality, exclude mesh from the viscera, limit infection and wound complications, and minimize pain...

Minimally invasive surgical approaches in transplantation are gaining increasing interest, and many centers are reporting their, mainly laparoscopic, experiences. Robotic surgery (RS) has some hypothetical advantages over traditional laparoscopy, and has been successfully applied, although infrequently to organ transplantation. Our goal was to review and critique the publications reporting RS use in organ transplantation. Most of the RS experience has been with living renal donor organ procurement and, to a lesser extent, with RS procedures in the transplant recipient...

Road sign comprehension plays an important part in road safety management, particularly for those drivers who are travelling in an unfamiliar country. Previous research has established that comprehension can be improved if signs are designed to adhere to ergonomic principles. However, it may be difficult for sign designers to incorporate all the principles into a single sign and may thus have to make a judgement as to the most effective ones. This study surveyed drivers in three countries to ascertain their understanding of a range of road signs, each of which conformed in varying degrees and combinations to the ergonomic principles...

Green buildings are designed to have low environmental impacts and improved occupant health and well-being. Improvements to the built environment including ventilation, lighting, and materials have resulted in improved indoor environmental quality (IEQ) in green buildings, but the evidence around occupant health is currently centered around environmental perceptions and self-reported health. To investigate the objective impact of green buildings on health, we tracked IEQ, self-reported health, and heart rate in 30 participants from green and conventional buildings for two weeks...

What prevents the delivery of effective, high quality, and safe healthcare in the National Health Service (NHS) in England? This paper presents 760 challenges which 330 NHS staff reported as preventing the delivery of effective, high quality and safe care. Some problems have been known for over 25 years (staff shortages, finance and patient complexity) but other challenges raise questions about the commitment of the NHS to patient and staff safety. For example Organisational Culture leading to 'stifling bureaucracy', 'odds stacked against smooth […] working' and Workload resulting in 'firefighting daily' and 'perpetual crisis mode'...

INTRODUCTION AND OBJECTIVE: Transrectal ultrasound guided prostate biopsy (TRUS-Bx) is the definitive step in the diagnosis of prostate cancer (CaP). Patients (pts) generally experience significant pain during the procedure at the point that biopsy should be accompanied by some form of anesthesia. Several different factors influence pain perception (PP) during TRUS-Bx. In our study we want to assess that the use of an ergonomic smaller sized probe reduces PP during the procedure independently from the administration of local anesthesia or pain relieving drugs...
