This beautiful testament to the power and magic of equine energy captures the soul of a horse perfectly. Susan Richards, Author, Chosen By a HorseFrom the Back CoverHorse training presents unique opportunities to explore powerful spiritual truths. The exercises in Zen Mind, Zen Horse offer everyone who works with horses -- novice or expert -- a new understanding of how humans train and interact with horses and why these two species, one a master predator and the other the ultimate prey animal, have such a deep, natural connection. Horses have evolved to understand and respond to the flow of vital energy -- chi -- around them, using it in their body language to communicate with members of their herd, to express dominance, and to sense danger from nearby predators. Being quietly present and receptive to your horse's energy opens the potential of your emotional, intuitive right brain. These simple, safe groundwork techniques reveal a pathway to awakening your deep sensitivity, calm leadership, intuition, and mindfulness.
- Hamilton, A. J. (2008). The Scalpel and the Soul. New York: Penguin/Tarcher.More infoFrom Publishers WeeklyHamilton has led a remarkable life as a neurosurgeon. There are moments in this spiritual memoir when readers will wish he were their personal guide for the scariest of surgeries. In many ways, this is a story about real doctors as Hamilton understands them—people with exemplary bedside manners who not only make life-and-death decisions for the most vulnerable of the sick, but who have the vision (sometimes literally) to sit and listen as long as it takes, to take patients' hands, dealing with their questions and fears with the utmost gentleness and an eye toward the transcendent and supernatural. Readers will be moved by stories of former patients like Thomas, a child burn victim with such a gift of spirit that he could manage joy despite his tragic condition, and Donald, a brave man determined to live life to the fullest despite a vicious brain tumor. Hamilton's voice soars when he reflects directly on his experience as a brain surgeon, the bulk of which occurs (unfortunately) in the book's second half. In light of these high points, Hamilton's occasionally stumbling and awkward prose when straying from his patients' sides can seem jarring.

[Epub ahead of print]PMID: 32034416AbstractINTRODUCTION:Equine-assisted therapy (EAT) for post-traumatic stress disorder (PTSD) has attracted great interest despite lacking empirical support, a manual, and a standardized protocol. Our team of experts in EAT and PTSD developed an eight-session group EAT treatment protocol for PTSD (EAT-PTSD) and administered it to two pilot groups of military veterans to assess initial effects.MATERIALS AND METHODS:We describe the development of the treatment manual, which was used with two pilot groups of veterans. Protocol safety, feasibility, and acceptability were assessed by reported adverse events, treatment completion rates, and self-rated patient satisfaction. Preliminary data on PTSD, depressive, and anxiety symptoms and quality of life were collected pretreatment, midpoint, post-treatment, and at 3-month follow up.RESULTS:No adverse events were recorded. All patients completed treatment, reporting high satisfaction. Preliminary data showed decreases in clinician-assessed PTSD and depressive symptoms from pre to post-treatment and follow-up (medium to large effect sizes, d = .54-1.8), with similar trends across self-report measures (d = 0.72-1.6). In our pilot sample, treatment response and remission varied; all patients showed some benefit post-treatment, but gains did not persist at follow-up.CONCLUSIONS:This article presents the first standardized EAT protocol. Highly preliminary results suggest our new manualized group EAT-PTSD appears safe, well-regarded, and well-attended, yielding short-term benefits in symptomatology and quality of life if unclear length of effect. Future research should test this alternative treatment for PTSD more rigorously.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2019.

Surgical Innovation. doi:https://doi.org/10.1177/1553350620957799More infoAbstractBackground. To overcome field of view and ergonomic limitations of standard laparoscopes, we are developing a multi-resolution foveated laparoscope (MRFL), which can simultaneously obtain both wide- and zoomed-in-view images. To facilitate the effectiveness of our MRFL, we have been investigating various ways of organizing and visualizing dual-view multi-resolution images acquired by the MRFL. In our prior study, we implemented and compared 6 display modes for the MRFL, assuming a typical clinical environment where a standard (but limited) resolution monitor is available. To take full advantage of our MRFL, displays having sufficient screen resolutions might be advantageous. The present study aims to further understand the effects of view configurations through displays with a standard high-definition (HD) resolution and a 4K resolution. In this study, we compare 3 display modes for limited-resolution displays against a new mode for sufficient-resolution displays. Methods. Twenty subjects performed 3 evaluation trials of a touching task with each display mode in an emulated MRFL environment. Various objective measurements including task completion time and the number of collisions, and subjective preference were recorded. Results. The new mode showed a better task completion time than the other modes, while it maintained a low number of collisions similar to the others. Moreover, the majority of participants selected the new mode as their most preferred one. Conclusions. With a sufficient display resolution, the co-registration between the unblocked and unwarped wide context view and the high-resolution zoomed-in view offered by the new mode was highly effective on both task performance and user preference.Keywords laparoscope, display interface, dual views, multi-resolution visualization, focus plus context, overview plus detail

To facilitate the effective access to the dual views of images with different resolution and field coverage acquired by our laparoscope, six different display modes have been developed. Each of the six display modes has inherent advantages and disadvantages. This study compares the six display modes through a human-subject experiment, which was conducted with an emulated laparoscope using a 4K camera.

Cureus, 10(9), e3327.More infoObjectives Emergency medicine (EM) residents are required to perform a cricothyrotomy during training as per the Accreditation Council for Graduate Medical Education (ACGME) guidelines. Cricothyrotomy is a rare procedure, comprising 0.45% of emergency department airway management procedures. Procedural competence in utilizing a realistic trainer is of utmost importance. We have developed a cricothyrotomy trainer using a fused deposition modeling (FDM) three-dimensional (3D) printer and innovative bleeding tissue to enhance fidelity. We aim to evaluate the trainer's realism. Methods Implementation occurred during a difficult airway educational lab for EM residents in April 2018. Participants completed anonymous written surveys after performing a cricothyrotomy on the trainer. The survey evaluated the realism of the trainer and compared it to other available models by utilizing five-point visual analog scales (VAS). The participants rated their comfort level in performing the procedure pre- and post-educational lab on a five-point VAS. Demographic data included postgraduate year, prior clinical cricothyrotomy experience as a primary operator versus as an assistant, and previous trainer experience. The survey included open-response suggestions for trainer improvement. Results Forty-three EM residents completed the survey (82.7%, 43/52). The mean realism rating of the trainer was 3.81 (95% CI = 3.54-4.1). The participants reported previous training on cadaver (62.8%, 27/43), porcine (46.5%, 20/43), and manikin (67.4%, 29/43) models prior to using this trainer. The bleeding cricothyrotomy trainer was rated higher than other models (4.45, 95% CI = 4.28-4.63). Participants noted improved comfort with performing the cricothyrotomy after the educational lab (average improvement of 1.23±0.75). Participants specifically commented on the realism of the bleeding and skin texture; however, they also recommended a reduction in the size of the cricothyroid membrane space. Conclusion The innovative bleeding cricothyrotomy trainer has greater fidelity and reported superiority when compared to other commonly used nonbleeding models. This trainer provides a more advanced platform to teach an infrequent yet critical procedural skill to emergency medicine residents.

Air Medical Journal, 35(5), 308-13.More infoLimited clinical site availability and an increased need for clinical training experiences often make it difficult for prehospital health care providers to complete new and annual training requirements. Medical simulation provides an alternative learning environment that provides trainees the opportunity to acquire and perfect new clinical skills without compromising patient care. The following is a detailed description of an air medical transport simulation of a neonate with hypoxic ischemic encephalopathy requiring transport to a higher level of care. Patient parameters were altered during flight to simulate potential complications unique to air medical transport. Use of this training strategy is particularly beneficial for low-volume, high-risk patients, and these lessons can be applied across all age patient groups, making the experience broadly applicable.

Construction of a reusable, high-fidelity model to enhance extracorporeal membrane oxygenation training through simulation. Advances in neonatal care : official journal of the National Association of Neonatal Nurses, 14(2), 103-9.More infoInitiation of extracorporeal membrane oxygenation (ECMO) is stressful, especially for inexperienced extracorporeal life support providers. The main objective of this study was to create a novel, reusable mannequin for high-fidelity simulation of ECMO initiation. We modified a Laerdal neonatal mannequin (SimNewB; Stavanger, Norway) so that it could be used to simulate an ECMO initiation. A simulation of a neonatal patient suffering from meconium aspiration was performed in the pediatric intensive care unit, and participants included new extracorporeal life support specialists in addition to the composition of the clinical ECMO team. A total of 17 individuals participated in the neonatal ECMO initiation simulation. Questionnaire results showed that 88% of participants felt better prepared to assist in an ECMO initiation after the simulation. All participants (100%) agreed that the modified mannequin and the environment were realistic and that this simulation helps teamwork and communication in future initiations of ECMO. Simulation can be used for the prevention, identification, and reduction of anxiety-related crisis situations that novice providers may infrequently encounter during routine clinical use of mechanical circulatory support. Use of a reusable, high-fidelity mannequin may be beneficial for effective team training of complex pediatric ECMO-related procedures.

Journal of Endourology, 24(3), 377-9.More infoLaparoscopic surgery is well known as having a long and variable learning curve. In fact, successive generations of surgeons were able to reduce their operative time and plateau their learning curves. This raises the question as to how early in medical education we can integrate laparoscopic skills. In this study, we are trying to demonstrate the effect of age on acquiring new laparoscopic skills.

Assessing radiology resident preparedness to manage IV contrast media reactions using simulation technology. Studies in health technology and informatics, 142, 139-41.More infoInvestigate whether radiology residents make correct diagnosis of contrast media reactions and evaluate their treatment of reaction using simulation technology. Residents were presented with a test scenario of patient given IV contrast having anaphylactic reaction. A computer-run mechanical mannequin that simulates, with mathematical, pharmacokinetic, pharmacodynamic and cardiovascular algorithms, was used. Sessions were evaluated with respect to whether residents performed key actions to treat anaphylaxis. Times were recorded. All residents recognized the contrast reaction and initiated basic actions. As the scenario progressed and patient deteriorated, all recognized need to intubate, but intubation performance varied significantly. Radiology residents generally not prepared to deal with IV contrast reactions. Simulation technology to practice key actions would improve their preparedness.

A phase I trial of Ad.hIFN-beta gene therapy for glioma. Journal of the American Society of Gene Therapy, 16(3), 618-26.More infoInterferon-beta (IFN-beta) is a pleiotropic cytokine with antitumoral activity. In an effort to improve the therapeutic index of IFN-beta by providing local, sustained delivery of IFN-beta to gliomas, the safety and biological activity of a human IFN-beta (hIFN-beta)-expressing adenovirus vector (Ad.hIFN-beta) was evaluated in patients with malignant glioma by stereotactic injection, followed 4-8 days later by surgical removal of tumor with additional injections of Ad.hIFN-beta into the tumor bed. Eleven patients received Ad.hIFN-beta in cohorts of 2 x 10(10), 6 x 10(10), or 2 x 10(11) vector particles (vp). The most common adverse events were considered by the investigator as being unrelated to treatment. One patient, who was enrolled in the cohort with the highest dose levels, experienced dose-limiting, treatment-related Grade 4 confusion following the post-operative injection. Ad.hIFN-beta DNA was detected within the tumor, blood, and nasal swabs in a dose-dependent fashion and hIFN-beta protein was detectable within the tumor. At the highest doses tested, a reproducible increase in tumor cell apoptosis in post-treatment versus pre-treatment biopsies with associated tumor necrosis was observed. Direct Ad.hIFN-beta injection into the tumor and the surrounding normal brain areas after surgical removal was feasible and associated with apoptosis induction.

WHEN HOLLYWOOD INSPIRES MEDICINE: NEW CONCEPTS IN THE DESIGN AND ARCHITECTURE OF MEDICAL SIMULATION FACILITIES TO SUPPORT MULTI-DISCIPLINARY AND INTER-PROFESSIONAL HEALTHCARE EDUCATION AND TRAINING. In Annual Conference on Medical Modeling and Engineering Practices, TBA, TBA.More infoABSTACTThe changing landscape of healthcare education, delivery, and technology is placing new demands for significant inter-disciplinary and inter-professional training in medical simulation. New architectural concepts and building designs must ensure that large-scale healthcare simulation facilities offer customized training opportunities for nursing, medicine, pharmacy and public health, while allowing for maximal flexibility and adaptation across nearly fifty different user groups and stake holders. A novel concept of a larger, configurable “stage” design, more akin to a Hollywood production studio, with in-patient and out-patient suites operationalized as temporary or “standing” sets was created as the centerpiece of a new, futuristic, 220,000 square foot health science education building. The stage, called a “sim deck,” can be easily dismantled or reconfigured while providing ample square footage for mass casualty scenarios. The facility required significant technological support to provide remote simulation training via existing and future telemedical technologies as well as remaining nimble enough to incorporate technologies in augmented and virtual reality, artificial intelligence, and large-scale learner management systems.
