Cervical Spine Alignment

Abstract Context: Removal of the lacrosse helmet to achieve airway access has been discouraged based only on research in which cervical alignment was examined. No researchers have examined the effect of lacrosse equipment on the cervical space available for the spinal cord (SAC). Objective: To determine the effect of lacrosse equipment on the cervical SAC and cervical-thoracic angle (CTA) in the immobilized athlete. Design: Observational study. Setting: Outpatient imaging center. Patients or Other Participants: Ten volunteer lacrosse athletes (age  =  20.7 ± 1.87 years, height  =  180.3 ± 8.3 cm, mass  =  91 ± 12.8 kg) with no history of cervical spine injury or disease and no contraindications to magnetic resonance imaging (MRI). Intervention(s): The lacrosse players were positioned supine on a spine board for all test conditions. An MRI scan was completed for each condition. Main Outcome Measure(s): The independent variables were condition (no equipment, shoulder pads only [SP], and full gear that included helmet and shoulder pads [FG]), and cervical spine level (C3–C7). The dependent variables were the SAC and CTA. The MRI scans were evaluated midsagittally. The average of 3 measures was used as the criterion variable. The SAC data were analyzed using a 3 × 5 analysis of variance (ANOVA) with repeated measures. The CTA data were analyzed with a 1-way repeated-measures ANOVA. Results: We found no equipment × level interaction effect (F3.7,72  =  1.34, P  =  .279) or equipment main effect (F2,18  =  1.20, P  =  .325) for the SAC (no equipment  =  5.04 ± 1.44 mm, SP  =  4.69 ± 1.36 mm, FG  =  4.62 ± 1.38 mm). The CTA was greater (ie, more extension; critical P  =  .0167) during the SP (32.64° ± 3.9°) condition than during the no-equipment (25.34° ± 2.3°; t9  =  7.67, P  =  .001) or FG (26.81° ± 5.1°; t9  =  4.80, P  =  .001) condition. Conclusions: Immobilizing healthy lacrosse athletes with shoulder pads and no helmets affected cervical spine alignment but did not affect SAC. Further research is needed to determine and identify appropriate care of the lacrosse athlete with a spine injury.

The Microscopy and Imaging Center at Texas A&M University is a multi-user facility involved with preparation and analysis of many different biological and materials sciences projects. Vapor stabilization and coating is an important part of our specimen preparation methodology for difficult biological and materials, especially polymer, samples. The procedure for all our vapor preparation techniques is done in a simple, economical apparatus set up in a properly functioning fume hood with a flow rate of at least 100 ft/min (Fig. 1). The apparatus is made from a glass petri dish or a glass petri dish for the bottom and an appropriate size beaker for the top. Specimens, mounted on stubs, are placed inside the chamber and the fixative (osmium tetroxide, ruthenium tetroxide or acrolein) is placed in a small container (plastic bottle cap) near the specimens.

Building Project

A new state-of-the-art fine arts complex for our College will soon open and it includes an Imaging Center: a physical environment that will support activities related to the teaching and research use of images. A parallel building project is happening simultaneously: the development of digital content and tools to enable imaging across the campus. The bricks and mortar effort will soon result in a spectacular sunrise. As far as content and tools go, we’re still in the deepest dark before dawn, i.e. we’re not there yet. As one faculty member put it, ‘That’s nice, but now what I really need …’. These few words speak volumes about user expectations and the extraordinary effort it takes to meet them.

Low Middle Income Countries

Abstract Background The greater burden of coronary heart disease (CHD) comes from low-middle income countries (LMIC). Socioeconomic status, environmental factors, poor access to healthcare, physical inactivity and excess consumption of carbohydrates, have explained part of this burden. However, the association between income level and CHD in LMIC with marked social inequalities is not fully understood, and whether there is influence of neighborhood walkability (walking-promoting potential of the residential built environment for daily activities) in this association requires further investigation. Purpose To investigate to what level income is associated with ischemic CHD in a LMIC with great social inequalities and to explore the potential role of neighborhood walkability in this association. Methods We evaluated patients referred for myocardial perfusion imaging with SPECT (SPECT-MPI) from February 2010 to August 2017 at a reference imaging center in our city, Brazil. Each patient was georeferenced and the exposure variable was the average income in Brazilian currency (Real) per month, from the patient's residential census block. Ischemic CHD was defined by an abnormal myocardial perfusion (summed stress score >3) during a SPECT-MPI study. Walkability was measured by a score combining street connectivity, residential density, commercial density and mixed land use. We used mixed effects models to evaluate the association between income level and ischemic CHD, adjusted for potential confounders, and performed a mediation analysis to measure the percentage of this association mediated by walkability. Results From 26,810 participants, those living in the lowest tertile income neighborhoods were younger (61±12 vs 63±13 vs 65±12 yrs old); with higher body mass index (28.4±5 vs 27.7±5 vs 27.4±4 kg/m2); more likely to be women (52 vs 49 vs 47%), current smokers (10 vs 9 vs 8%), sedentary (79 vs 76 vs 73%), having diabetes (27 vs 24 vs 23%), hypertension (65 vs 62 vs 60%) and with known CHD (21 vs 20 vs 19%) when compared to the second and the highest tertiles respectively, all with p<0.001. After adjusting for these potential confounders, income level was inversely associated with ischemic CAD (Figure). Neighborhoods with higher income levels were associated with better walkability scores (R = 0.34eta; p<0.001), but walkability did not mediate the association between income level and ischemic CHD (percent mediated = −0.3%). Figure 1. Association of income and CHD Conclusions In this large registry from a LMIC population, living in a lower-income neighborhood was associated with higher prevalence of ischemic CHD. Even though neighborhood walkability was directly associated with neighborhood income, it did not explain the association between income level and ischemic CHD.

A partnership has developed between the Microscope and Graphic Imaging Center (MAGIC) at California State University, Hayward and Ohlone Community College. The purpose of the collaboration is to develop a program to allow community college students to gain experience in preparing and viewing samples using scanning electron microscopy technology. The learning module involves students from the Ohlone College Biology Majors Program and student mentors from CSUH. An additional component is the introduction of under-represented students into a Biology Fellowship Program in which they also participate in the SEM learning module. Participants for these programs are selected on the basis of their interest and how this experience will benefit them as expressed in a one-page written essay. Ten students are selected to participate in the programs.The objectives of the learning module are to: 1) learn specimen preparation techniques and develop skills in SEM technology; 2) gain hands-on experience and develop some laboratory skills necessary for effective use of a SEM in studying biological specimens; 3) share the experience gained with peers at their home institution.
