We present Oasis, a novel system for automatically generating immersive and interactive virtual reality environments for single and multiuser experiences. Oasis enables real-walking in the generated virtual environment by capturing indoor scenes in 3D and mapping walkable areas. It makes use of available depth information for recognizing objects in the real environment which are paired with virtual counterparts to leverage the physicality of the real world, for a more immersive virtual experience. Oasis allows co-located and remotely located users to interact seamlessly and walk naturally in a shared virtual environment...

Applying simulation in medical education is becoming more and more popular. The use of simulation in medical training has led to effective learning and safer care for patients. Nowadays educators have confronted with the challenge of respecting patient safety or bedside teaching. There is widespread evidence, supported by robust research, systematic reviews and meta-analysis, on how much effective simulation is. Simulation supports the acquisition of procedural, technical and non-technical skills through repetitive practice with feedbacks...

REVIEW
Souya Nunobe, Naoki Hiki
The number of early gastric cancer (EGC) cases has been increasing because of improved diagnostic procedures including endoscopy and screening systems. Therefore, function-preserving gastrectomy (FPG) for EGC with the expectation of better quality of life (QOL) after surgery may be increasingly utilized, due to its association with low rate of lymph node metastasis and excellent survival and the possibility of employing less invasive procedures such as laparoscopic gastrectomy in combination. Pylorus-preserving gastrectomy (PPG) with curative intent lymph node dissection is a representative FPG that has been used in EGC, and its superiorities, indications, limitations, and survival benefits have already been reported in several retrospective studies...

Early hospital readmission has become a proxy for quality of care and contributes significantly to high health care costs in the United States, with more than $20 billion health care dollars are spent on 30-day readmission annually. Cranial neurosurgical procedures (i.e., craniotomy, craniectomy) are associated with high readmission rates; however, studies examining readmission after cranial procedures are limited and relatively unknown. The aim of this study is to identify the drivers of 30-day unplanned readmission in consecutive patients undergoing craniotomies and craniectomies...

BACKGROUND: Since the end of the XIX century, teaching of surgery has remained practically unaltered until now. With the dawn of video-assisted laparoscopy, surgery has faced new technical and learning challenges. Due to technological advances, from Internet access to portable electronic devices, the use of online resources is part of the educational armamentarium. In this respect, videos have already proven to be effective and useful, however the best way to benefit from these tools is still not clearly defined...

Due to a national theoretical training provided to all resident for many years and the ongoing discussions to change the organization of the resident training of specialized study diploma (SSD) of nephrology, a survey was done to assess the perception of skills acquired in the management of different clinical situations in terms of knowledge, expertise and attitudes. The expected results are intended to identify new training procedures for future nephrologists in France. The study was performed in 112 resident from 3rd and 4th year of nephrology resident training attending an educational seminar of the University College of Nephrology Teachers in May 2014...

Image-guided percutaneous biopsy of cervical lymph nodes is a minimally invasive method performed for the characterization of abnormal lymph nodes, staging, and for the detection of regional tumor recurrence. When performed with proper technique and by a skilled proceduralist, this technique offers a very high diagnostic yield and can potentially save the patient from more invasive procedures. Its diagnostic role in different disease processes and the variations in technique as well as its potential risks and pitfalls will be discussed in this article...

BACKGROUND: Surgical education relies on operative exposure with live patients. Carotid endarterectomy (CEA) demands an experienced surgeon with a very low complication rate. The high-risk nature of this procedure and the decline in number of CEAs performed annually has created a gap in residency training. OBJECTIVE: To develop a high-fidelity whole-task simulation for CEA that demonstrates content, construct, and face validity. METHODS: Anatomically accurate models of the human neck were created using multilayered poly-vinyl alcohol hydrogels...

OBJECTIVE: We examined associations between sleep problems, distress intolerance, and perceived stress and health in a convenience sample of homeless adults. METHODS: Participants (N = 513, 36% women, Mage = 44.5 ±11.9) self-reported sleep adequacy, sleep duration, unintentional sleep during the daytime, distress tolerance, urban stress, and days of poor mental health and days of poor physical health over the last month. The indirect effects of sleep problems on stress and health through distress tolerance were examined using a non-parametric, bias-corrected bootstrapping procedure...

Challenge: Clinical and research responsibilities often leave little or no time to plan thoughtful teaching encounters with trainees. This "Teaching & Learning Tips" series is designed to be an accessible guide for dermatologists who want to improve their teaching skills. It is comprised of 12 articles about how to enhance teaching in various settings informed by research about how people learn and expert-derived or data-driven best practices for teaching. The series begins with a review of principles to optimize learning in any setting, including cognitive load theory, active learning strategies, and the impact of motivation and emotion on learning...

Maxillary sinus floor elevation has been documented as a safe and predictable procedure for gaining vertical bone height in the atrophic posterior maxillae. Conversely, there is a lack of basic research on the characteristics of the union between the sinus membrane (SM) and the bone. Clinical implications of an impaired union in healthy or pathologic membranes remain unknown. The objective of this study was to present a comprehensive histologic and morphologic description of the sinus membrane-lateral bone wall complex...

The school nurse plays a vital role in providing care and meeting the health needs of students in the school setting. Students attend school with chronic conditions and complex medical problems such as quadriplegia, cerebral palsy, spina bifida, and muscular dystrophy. It is the responsibility of the school nurse to provide appropriate assessment, early intervention, and care for children in the school environment. The purpose of this article is to review and discuss the knowledge and skills the school nurse needs to care for students with central venous lines, gastrostomy tubes, altered urinary elimination, and tracheostomies...

INTRODUCTION: Ventral incisional hernia is one of the most common procedures in laparoscopic surgery, however, it requires proper training before doing it in the operating room. We propose a low-cost mechanical simulator with a new optical system to learn the basic steps of the procedure and improve surgical laparoscopic skill. MATERIALS AND METHODS: From November 3, 2014 to January 4, 2015, five residents and five surgeons with no prior laparoscopic experience, as well as two laparoscopic expert surgeons, participated in our study...

Introduction Colonoscopy trainers have gained recognition for improving endoscopy skills and preparing for real procedures on humans. Unfortunately, due to their high price, commercial simulators are hard to obtain, especially for small medical centers. However, a solution might be to construct a device for themselves. Aim Our goal was to build a relatively cheap and easy-to-construct simulator for residents who want to start learning colonoscopy. Materials and methods The box model colonoscopy trainer was designed and constructed...
