Abstract: Linh N Tran,1 Priyanka Gupta,2 Lauren H Poniatowski,2 Shaheen Alanee,3 Marc A Dall’Era,4 Robert M Sweet21Department of Internal Medicine, Loma Linda University, Loma Linda, CA, 2Department of Urology, University of Minnesota, Minneapolis, MN, 3Urology Service, Department of Surgery, Memorial Sloan-Kettering Cancer Center, New York, NY, 4Department of Urology, University of California, Davis, CA, USABackground: Technological advances have dramatically changed medical education, particularly in the era of work-hour restrictions, which increasingly highlights a need for novel methods to teach surgical skills. The purpose of this study was to evaluate the validity of a novel, computer-based, interactive, cognitive simulator for training surgeons to perform pelvic lymph node dissection (PLND).Methods: Eight prostate cancer experts evaluated the content of the simulator. Contextual aspects of the simulator were rated on a five-point Likert scale. The experts and nine first-year residents completed a simulated PLND. Time and deviations were logged, and the results were compared between experts and novices using the Mann–Whitney test.Results: Before training, 88% of the experts felt that a validated simulator would be useful for PLND training. After testing, 100% of the experts felt that it would be more useful than standard video training. Eighty-eight percent stated that they would like to see the simulator in the curriculum of residency programs and 56% thought it would be useful for accreditation purposes. The experts felt that the simulator aided in overall understanding, training indications, concepts and steps of the procedure, training how to use an assistant, and enhanced the knowledge of anatomy. Median performance times taken by experts and interns to complete a PLND procedure on the simulator were 12.62 and 23.97 minutes, respectively. Median deviation from the incorporated procedure pathway for experts was 24.5 and was 89 for novices.Conclusion: We describe an interactive, computer-based simulator designed to assist in mastery of the cognitive steps of an open surgical procedure. This platform is intuitive and flexible, and could be applied to any stepwise medical procedure. Overall, experts outperformed novices in their performance on the trainer. Experts agreed that the content was acceptable, accurate, and representative.Keywords: simulation, surgical education, training, simulator, video

Abstract: Increasing numbers of medical undergraduates from lower socioeconomic backgrounds: positive for health care? Letter (436) Total Article Views Authors: Lemon TI, Stone BA Published Date March 2013 Volume 2013:4 Pages 39 - 41 DOI: http://dx.doi.org/10.2147/AMEP.S42814 Received: 15 January 2013 Accepted: 04 February 2013 Published: 21 March 2013 TI Lemon, B A Stone Cardiff University, School of Medicine, Cochrane Medical Education Centre, Heath Park, Cardiff, Wales Economic stagnation in the UK has been a prominent issue for the last five years, leading to an increase in unemployment and a subsequent rise of numbers in the lower socioeconomic classes.1 Seyan et al2 have shown that students from the lower socioeconomic classes are under-represented in medical schools. However, their study was carried out in a time of economic prosperity, and we suggest that this is reversed in times of economic deprivation, to the benefit of patients. Adaptation theory3 suggests that an organism suffering change in their environment will adapt to change and become better suited to survival. In this case, the organism is the adolescent population of the UK, the change in environment is the economic downturn, and in turn, their adaptation is to turn to professional jobs in order to provide themselves with secure income and live happier and healthier lives. Thus, it is reasonable to suggest that we will see growing numbers of medical students coming from the lower socioeconomic classes in the near future.

S. V. Chekanov,I. Pogrebnyak,D. Wilbern
Physics , 2015,
Abstract: A multi-platform validation and analysis framework for public Monte Carlo simulation for high-energy particle collisions is discussed. The front-end of this framework uses the Python programming language, while the back-end is written in Java, which provides a multi-platform environment that can be run from a web browser and can easily be deployed at the grid sites. The analysis package includes all major software tools used in high-energy physics, such as Lorentz vectors, jet algorithms, histogram packages, graphic canvases, and tools for providing data access. This multi-platform software suite, designed to minimize OS-specific maintenance and deployment time, is used for online validation of Monte Carlo event samples through a web interface.
Validation Processes of Protein Biomarkers in Serum—A Cross Platform Comparison  [PDF]

Sensors , 2012, DOI: 10.3390/s120912710
Abstract: Due to insufficient biomarker validation and poor performances in diagnostic assays, the candidate biomarker verification process has to be improved. Multi-analyte immunoassays are the tool of choice for the identification and detailed validation of protein biomarkers in serum. The process of identification and validation of serum biomarkers, as well as their implementation in diagnostic routine requires an application of independent immunoassay platforms with the possibility of high-throughput. This review will focus on three main multi-analyte immunoassay platforms: planar microarrays, multiplex bead systems and, array-based surface plasmon resonance (SPR) chips. Recent developments of each platform will be discussed for application in clinical proteomics, principles, detection methods, and performance strength. The requirements for specific surface functionalization of assay platforms are continuously increasing. The reasons for this increase is the demand for highly sensitive assays, as well as the reduction of non-specific adsorption from complex samples, and with it high signal-to-noise-ratios. To achieve this, different support materials were adapted to the immobilized biomarker/ligand, allowing a high binding capacity and immobilization efficiency. In the case of immunoassays, the immobilized ligands are proteins, antibodies or peptides, which exhibit a diversity of chemical properties (acidic/alkaline; hydrophobic/hydrophilic; secondary or tertiary structure/linear). Consequently it is more challenging to develop immobilization strategies necessary to ensure a homogenous covered surface and reliable assay in comparison to DNA immobilization. New developments concerning material support for each platform are discussed especially with regard to increase the immobilization efficiency and reducing the non-specific adsorption from complex samples like serum and cell lysates.

Abstract: The development of skills and abilities in laparoscopy is directly related to the use of trainers. The trainer should model the patient with all its natural complexities as closely as possible. In this article we propose a system for training the establishment of pneumoperitoneum executing the basic tasks to create the workspace in the trainer, the insertion of primary umbilical trocar and simulate some of the everyday problems in surgery. Materials and Methods. A group of electrical with biomedical engineers and laparoscopic surgeons developed a physical trainer that allows implementing the pneumoperitoneum. The system uses pneumatic electro valves that are controlled with a dedicated microprocessor. The user can program the system to set the parameters of the pneumoperitoneum. Results. This new trainer facilitated the programming of right values of parameters to distend the abdominal cavity according a specific clinical case. The model developed enables the trainee to consolidate his knowledge on establishing the parameters required within clinical practice, as well as the entry techniques. Conclusions. A new physical model for laparoscopic training was designed. The system enables the laparoscopic surgeon to set the parameters for establishing the workspace according to the clinical case. The trainer allows the surgeon to train in the Hasson technique for the introduction of the first trocar, as well as the placement of the rest of surgical instruments with video assistance. We think this new trainer system will help minimize entry-related injuries.

Abstract: Evaluation of the effectiveness of a cheaper newly developed web cam trainer to assist surgeons in developing basic laparoscopic skills in comparison to other inexpensive trainers was our objective to make this study. This newly developed web cam trainer consists of a web cam (equipped with a light source and light sensor), a foam box and a home computer. This homemade trainer was compared to the cardboard trainer developed by End urology Institute, Cedars-Sini Medical Center, which consists of a web cam, a cardboard box, a desk lamp and a home computer. A total of twelve participants at the National Institute of Urology and Nephrology, Cairo, Egypt were divided into two groups each using both trainers to perform basic tasks (pattern cutting and suturing the skin of a raw chicken). Time of the participants to perform each task was used to evaluate the effectiveness of both trainers (performance time). Statistical analysis of the 3 tasks comparing between this web cam trainer and the cardboard web trainer, developed by end urology Institute, Cedars-Sini Medical Canter, showed no statistical significance between both web trainers during performing task 1 (p = 0.590), but there was significant statistical difference during performing tasks 2 and 3 (p≤0.001). We conclude that this web cam pelvitrainer simulates for novice laparoscopists an easier way to develop basic laparoscopy skills without the need for expensive instruments and specialized training centers. In addition, the ability to review recorded tasks allows the trainee to learn their mistakes and how to overcome them. It is also superior to the cardboard trainer in performing tasks requiring complex skills.

Journal of Animal and Veterinary Advances , 2012,
Abstract: New training methods which rely on the ethological characteristics of the horse are spreading in the horse world. Some of them highlight the importance of trainer-horse eye contact during training in the round pen. The aim of this study was to assess the effects of eye contact with the trainer on the behaviour of saddle horses during training. Ten horses, aged 4 to 17 years, were subjected to two training sessions in the round pen, one in which the trainer was wearing very dark sunglasses, the other in which the trainer was wearing normal transparent glasses. The latency of some behaviour patterns which are deemed to be representative of the horse s attention towards the trainer and acceptance of the trainer as a social leader, were measured. The results show that horses oriented the inner ear towards the trainer, sham-chewed, lowered the head, stopped, approached and followed the trainer sooner (p<0.01) when the trainer was wearing transparent rather than dark glasses.
The basket trainer: A homemade laparoscopic trainer attainable to every resident  [cached]

Journal of Minimal Access Surgery , 2010,
Abstract: Laparoscopic trainers have been proved to be effective to improve skills of laparoscopic surgery; they are usually installed at hospital in the surgical department with limited access hours, usually inconvenient to the schedule of the resident. Simple trainer boxes are necessary for residents who desire developing their skills at home independently to the venue and hours of surgical departments. Our goal is to bring the laparoscopic trainer to the desktop of the surgical resident by making it very cheap, small, light, secure and easy to construct. We describe a model of laparoscopic trainer using steel basket which, we believe, meets all of the above-mentioned requirements. It is accessible to any personal budget and can be constructed with a minimum of hand skill. It is small and light enough to permit its daily use on the desktop of the resident for a couple of hours, then after it can be stocked in any locker.
