A Survey of Safety Recommendations for All-Terrain Vehicle Dealers and Track Owners in Kansas

Introduction. All-terrain vehicles (ATVs) are associated with injury,mortality, and healthcare costs. ATV related injuries are less severewhen consistent safety practices are followed, however, ATV safetyregulations are varied among states. This study sought to surveyKansas ATV dealers and track owners to determine safety promotionpractices. Methods. A cross-sectional telephone survey was conducted ofKansas ATV dealers and tracks. Survey questions included promotionand sale of safety equipment, provision of ATV safety information,and respondent characteristics. Results. Of those contacted, 32% of dealers and 31% of tracksresponded to the survey. Most ATV dealers sell safety gear (70% -100%) and all recommend safety gear to buyers and riders. All ATVtracks reported requiring helmets (100%) but were varied regardingother forms of safety gear. The majority of ATV dealers (77%) recommendedsafety courses, but only 31% of dealers and 40% of tracksoffered courses. Eighty percent of ATV tracks and 52% of dealers feltthey had a professional responsibility to educate riders/owners onsafety. Conclusions. Safety promotion by ATV dealers in Kansas consistentlywas recommended, but often limited to the sales of safety gear(helmets and gloves) or the provision of manufacturer provided safetymaterials. Further, ATV dealers reported rarely offering skills tests orsafety courses to buyers. In Kansas, safety promotion at the point ofsale or track level could be improved to increase public awareness ofATV safety practices. KS J Med 2017;10(4):76-78

Clinical Outcomes of Intermediate-Length Cephalomedullary Nails for Intertrochanteric Femur Fracture Repair in Older Adults

Introduction. Hip fracture is a major cause of morbidity and mortality in older adults. Intertrochanteric hip fractures often are treated surgically using cephalomedullary nails (CMN), in either a short or long length. Their outcomes are documented in the literature; however, outcomes of the intermediate-length CMN have not been well described. Methods. A retrospective review was conducted of older adults with intertrochanteric hip fractures that were treated with cephalomedullary nail fixation using an intermediate-length (235 mm Synthes Trochanteric Fixation® nail or 240 mm Stryker Gamma 3®) nail. Outcome data were collected during the inpatient stay and 16 months post-operatively. Results. Seventy-seven patients met inclusion criteria and were reviewed during inpatient stay; however, only 42 had documented post-operative outcomes. Of those, two patients died post-discharge and were not included in the 16-month follow-up. Comparison of results to published literature suggested that intermediate-length nails are comparable to short-length nails with regard to time in the operating room and estimated blood loss. The rate of blood transfusion was lower and length of hospital stay was shorter than in comparable studies of both short- and long-length nails. There were no post-operative periprosthetic fractures in the 16-month follow-up. This rate was lower than published rates for short and long nails. The hardware failure rate (3/42, 7.1%) of intermediate-length nails was higher than comparison studies of both short- and long-length nails.    Conclusions. Patient outcomes for intermediate-length nails were similar to outcomes of shorter length nails. Utilization of the intermediate-length nail appears to be an effective treatment option for repair of intertrochanteric femur fractures. However, direct comparison is difficult since periprosthetic fracture rate may increase over time and nail length and hardware failure are not defined consistently in the literature.  Further study is needed with a larger sample size followed over a longer period of time to confirm our findings

Combining scanning haptic microscopy and fibre optic Raman spectroscopy for tissue characterization

The tactile resonance method (TRM) and Raman spectroscopy (RS) are promising for tissue characterization in vivo. Our goal is to combine these techniques into one instrument, to use TRM for swift scanning, and RS for increasing the diagnostic power. The aim of this study was to determine the classification accuracy, using support vector machines, for measurements on porcine tissue and also produce preliminary data on human prostate tissue. This was done by developing a new experimental set-up combining micro-scale TRM—scanning haptic microscopy (SHM)—for assessing stiffness on a micro-scale, with fibre optic RS measurements for assessing biochemical content. We compared the accuracy using SHM alone versus SHM combined with RS, for different degrees of tissue homogeneity. The cross-validation classification accuracy for healthy porcine tissue types using SHM alone was 65–81%, and when RS was added it increased to 81–87%. The accuracy for healthy and cancerous human tissue was 67–70% when only SHM was used, and increased to 72–77% for the combined measurements. This shows that the potential for swift and accurate classification of healthy and cancerous prostate tissue is high. This is promising for developing a tool for probing the surgical margins during prostate cancer surgery

Hyaluronate levels in donor organ washout effluents: a simple and predictive parameter of graft viability

The principal cause of primary non-function in orthotopic liver transplantation is thought to be preservation injury to the microvasculature. We, therefore, evaluated if effluent levels of hyaluronate, whose uptake is an endothelial cell marker, could predict early graft function and ultimate graft outcome in orthotopic liver transplantation. A total of 102 cases were studied in two phases. In the first phase, we attempted to determine if a correlation existed between effluent hyaluronate levels, early graft function and ultimate graft outcome. This phase of the study was also used to determine hypothetical cut-off values for hyaluronate which could discriminate between good and bad livers. Thirty-two livers orthotopically transplanted to randomly selected primary recipients were studied. After varying periods of static cold storage (4°C) in University of Wisconsin solution, the livers were reinfused with cold (4°C) lactated Ringer’s solution. The first 50 ml of the reperfusion effluent was collected from the infrahepatic vena cava. Effluent samples were analyzed for hyaluronate. Linear regression analysis demonstrated a significant correlation between effluent hyaluronate levels and post-operative aspartate and alanine aminotransferase levels (p<0.001 for both). Logistic regression demonstrated a highly significant correlation (p = 0.0056) between effluent hyaluronate levels and ultimate graft outcome. Generation of Receiver Characteristics Curves indicated that a level between 400 and 430 μg·l(−1) could possibly discriminate between good livers and those at risk of early graft failure. The authenticity of this hyaluronate cut-off level was further confirmed in the second phase of the study where 70 consecutive primary crossmatch-negative transplants were performed. A highly significant difference was observed in peak aspartate and alanine aminotransferase levels in the first week (p<0.0006 and p<0.0005, respectively) between livers with effluent hyaluronate levels≤400 μg·l(−1) and livers with hyaluronate levels higher than 400 μg·l(−1) Logistic regression revealed a highly significant correlation between effluent hyaluronate levels and graft success (p=0.0001). Since hyaluronate uptake by the microvascular endothelial cell is significantly greater than production, high hyaluronate effluent levels in failed livers would be due to decreased hyaluronate uptake by the injured microvascular endothelial cell. We therefore conclude that effluent hyaluronate levels may prove to be a reliable preoperative test to assess early graft function and outcome in clinical orthotopic liver transplantation

Early career members at the ers international congress 2017: Highlights from the assemblies

The 2017 ERS International Congress was, as always, well organised, providing participants with a good mixture of translational and clinical science. Early career members were very well represented in thematic poster, poster discussion and oral presentation sessions and were also actively involved in chairing sessions. The efforts of the Early Career Members Committee (ECMC) to increase the number of early career members included in the competence list (the list of early career members with an interest in being more actively involved in the society) paid off immensely, because the number of early career members registered improved hugely across all assemblies after the Congress. Several newly registered early career members have collated some highlights of the Congress for their assemblies, which should be of interest to all members. As assemblies 12 and 13 are new, there is no report from assembly 12 as there is not yet, at the time of writing, an early career member representative for this newly created assembly

Mass Casualties and Health Care Following the Release of Toxic Chemicals or Radioactive Material—Contribution of Modern Biotechnology

Catastrophic chemical or radiological events can cause thousands of casualties. Such disasters require triage procedures to identify the development of health consequences requiring medical intervention. Our objective is to analyze recent advancements in biotechnology for triage in mass emergency situations. In addition to identifying persons “at risk” of developing health problems, these technologies can aid in securing the unaffected or “worried well”. We also highlight the need for public/private partnerships to engage in some of the underpinning sciences, such as patho-physiological mechanisms of chemical and radiological hazards, and for the necessary investment in the development of rapid assessment tools through identification of biochemical, molecular, and genetic biomarkers to predict health effects. For chemical agents, biomarkers of neurotoxicity, lung damage, and clinical and epidemiological databases are needed to assess acute and chronic effects of exposures. For radiological exposures, development of rapid, sensitive biomarkers using advanced biotechnologies are needed to sort exposed persons at risk of life-threatening effects from persons with long-term risk or no risk. The final implementation of rapid and portable diagnostics tools suitable for emergency care providers to guide triage and medical countermeasures use will need public support, since commercial incentives are lacking

Spirit, mind and body: the archaeology of monastic healing

Archaeology and material culture are used in this chapter to consider how monastic experience responded to illness, ageing and disability. The approach taken is influenced by the material study of religion, which interrogates how bodies and things engage to construct the sensory experience of religion, and by practice-based approaches in archaeology, which examine the active role of space and material culture in shaping religious agency and embodiment. The archaeology of monastic healing focuses on the full spectrum of healing technologies, from managing the body in order to prevent illness, through to the treatment of the sick and preparation of the corpse for burial

Systematisation of spatial uncertainties for comparison between a MR and a CT-based radiotherapy workflow for prostate treatments

<p>Abstract</p> <p>Background</p> <p>In the present work we compared the spatial uncertainties associated with a MR-based workflow for external radiotherapy of prostate cancer to a standard CT-based workflow. The MR-based workflow relies on target definition and patient positioning based on MR imaging. A solution for patient transport between the MR scanner and the treatment units has been developed. For the CT-based workflow, the target is defined on a MR series but then transferred to a CT study through image registration before treatment planning, and a patient positioning using portal imaging and fiducial markers.</p> <p>Methods</p> <p>An "open bore" 1.5T MRI scanner, Siemens Espree, has been installed in the radiotherapy department in near proximity to a treatment unit to enable patient transport between the two installations, and hence use the MRI for patient positioning. The spatial uncertainty caused by the transport was added to the uncertainty originating from the target definition process, estimated through a review of the scientific literature. The uncertainty in the CT-based workflow was estimated through a literature review.</p> <p>Results</p> <p>The systematic uncertainties, affecting all treatment fractions, are reduced from 3-4 mm (1Sd) with a CT based workflow to 2-3 mm with a MR based workflow. The main contributing factor to this improvement is the exclusion of registration between MR and CT in the planning phase of the treatment.</p> <p>Conclusion</p> <p>Treatment planning directly on MR images reduce the spatial uncertainty for prostate treatments.</p
