Operative Treatment of Cervical Myelopathy: Cervical Laminoplasty
Brett A. Braly,David Lunardini,Chris Cornett,William F. Donaldson
Advances in Orthopedics , 2012, DOI: 10.1155/2012/508534
Abstract: Cervical spondylotic myelopathy (CSM) is a degenerative process which may result in clinical signs and symptoms which require surgical intervention. Many treatment options have been proposed with various degrees of technical difficulty and technique sensitive benefits. We review laminoplasty as a motion-sparing posterior decompressive method. Current literature supports the use of laminoplasty for indicated decompression. We also decribe our surgical technique for an open-door, or “hinged”, laminoplasty.

Abstract: Cervical spondylotic myelopathy (CSM) is a degenerative process which may result in clinical signs and symptoms which require surgical intervention. Many treatment options have been proposed with various degrees of technical difficulty and technique sensitive benefits. We review laminoplasty as a motion-sparing posterior decompressive method. Current literature supports the use of laminoplasty for indicated decompression. We also decribe our surgical technique for an open-door, or “hinged”, laminoplasty. 1. Introduction Cervical spondylotic myelopathy (CSM) is the natural result of degenerative compression on the cervical spinal cord. The result may be a progressive and stepwise deterioration of neurological function in patients. The chronic debilitating nature of this process justifies surgical decompression. Posterior decompression has been described as a treatment for CSM since the 1940s. Laminectomy was the initial surgical option used. The decompression was performed by rongeurs. However, the insertion of the rongeur in an already limited space available for the cord led often to a decrease in neurological function postoperatively [1–3]. Even with modern approaches to laminectomy using high speed burs, development of postoperative instability has led surgeons to explore more efficacious ways of decompression. In 1977, Hirabayashi and Satomi published their results on multisegment decompression by means of an open-door laminoplasty [4]. This technique allows for adequate posterior decompression of the spinal cord while retaining the posterior elements. This avoids the postoperative instability seen with laminectomy as well as the stiffness and risks of posterior cervical fusion. Additionally, motion is spared due to the absence of a fusion. There have since been multiple techniques for performing a cervical laminoplasty described with supporting literature [4–8]. These techniques include the expansive “open door,” a midline “French Door,” En Bloc resection, spinous process splitting, and Z-Plasty [4, 9]. Outcome studies have supported laminoplasty as a valid treatment for CSM however, no definitive literature shows its superiority to laminectomy in conjunction with a posterior cervical fusion. All surgical strategies appear to be equal in yielding neurologic outcomes, though differences are found in complication reports. Patient selection is crucial prior to proceeding with cervical laminoplasty. Special attention must be paid to sagittal alignment for optimal outcomes. Laminoplasty is ideal for multilevel stenosis (AP canal diameter < 13?mm) due to
Assessing and Addressing Health Literacy
Sandy Cornett
Online Journal of Issues in Nursing , 2009,
Abstract: The ability to communicate effectively with patients who have low health literacy depends on our ability to recognize this problem and to create a patient-centered and shame-free healthcare environment. Because of the shame and embarrassment these patients experience, they often use their well-developed coping skills to mask their limited literacy. Although a number of reading- and comprehension-assessment tools are available, there is debate whether or not these tools should be used clinically. This article provides guidance in regard to establishing an environment that promotes health literacy, assessing health literacy levels, utilizing strategies to increase health literacy, evaluating the learning that has occurred, and incorporating health literacy concepts into the nursing curriculum.
International vs. Intra-national Convergence in Europe – an Assessment of Causes and Evidence
Andreas P. Cornett,Nils Karl S?rensen
Investigaciones Regionales , 2008,
Abstract: The article aims to explain the different patterns of economic developmentin Europe based on an assessment of regional and national performancewith regard to innovation, entrepreneurship and difference in the industrial structure.The central hypothesis of the paper is that large intra-regional disparities donot necessarily lead to lower economic growth on the national level than smallerdisparities do. On the contrary, the polarization of economic activities can lead toexcess growth in some cases, and contribute to a process of convergence betweennations.To address the mechanisms behind this process, the long run patterns of convergenceand disparities in regional economic performance with regard to GDP and the distributionof employment are analyzed on the regional and the national level for selectedEuropean countries.The paper focuses on the apparent contradiction between increasing intra-nationaldisparities on the regional level in most industrialized countries and the overall tendencytoward convergence on the national level in Europe and tries to providesome tentative explanations based on empirical as well as theoretical considerations.
Implications of the Sample Rate on Large Space Telescopes
D. J. Fixsen,R. H. Cornett
Physics , 2002, DOI: 10.1023/A:1021835102574
Abstract: The frequency at which a large space telescope's (e.g. NGST's) detector chips are read, or the sample rate, is tightly coupled to many hardware and operational aspects of the telescope's instrument and data handling elements. In this paper we discuss many of the drivers and important implications fo the sample rate: the data rate to the ground; onboard computer storage, bandwidth, and speed; the number of A->D chips, and therefore the overall size and power requirements of the analog electronics; cryocabling requirements; and detector noise and power. We discuss and parametrize these and other elements related to sample rate. Finally, we discuss the implications of sample rate in the context of achieving the most important science goals under the constraint of fixed cost.
The Stationary Distributions of a Class of Markov Chains  [PDF]
Chris Cannings
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.45105
Abstract:

The objective of this paper is to find the stationary distribution of a certain class of Markov chains arising in a biological population involved in a specific type of evolutionary conflict, known as Parkers model. In a population of such players, the result of repeated, infrequent, attempted invasions using strategies from{0,1,2,,m-1}, is a Markov chain. The stationary distributions of this class of chains, for m ε {3,4,,} are derived in terms of previously known integer sequences. The asymptotic distribution (for m →∞) is derived.

The Prevalence of Sexual Partner Concurrency Is Not Correlated with Markers of Poverty or Gender Inequality: An Ecological Analysis  [PDF]
Chris Kenyon
World Journal of AIDS (WJA) , 2015, DOI: 10.4236/wja.2015.54035
Abstract: High rates of overlapping sexual relationships (concurrency) are believed to be important in the generation of generalized HIV epidemics in sub-Saharan Africa. Different authors favor socioeconomic, gender-equity or cultural explanations for the high concurrency rates in this region. We performed linear regression to analyze the association between the point-prevalence of concurrency in 15 - 49 years old males and various indicators of socioeconomic status and gender-equity using data from 11 countries surveyed in 1989/1990. We found no meaningful association between concurrency and the various markers of socioeconomic status and gender-equity. This analysis supports the findings of other studies that high concurrency rates in sub-Saharan Africa could be reduced without having to address socioeconomic and gender-equity factors.
Characterization of Fluorescent Eye Markers for Mammalian Transgenic Studies
Jonathan C. Cornett, Sean F. Landrette, Tian Xu
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0029486
Abstract: Genotyping mice by DNA based methods is both laborious and costly. As an alternative, we systematically examined fluorescent proteins expressed in the lens as transgenic markers for mice. A set of eye markers has been selected such that double and triple transgenic animals can be visually identified and that fluorescence intensity in the eyes can be used to distinguish heterozygous from homozygous mice. Taken together, these eye markers dramatically reduce the time and cost of genotyping transgenics and empower analysis of genetic interaction.
Coding Criminal Justice Interactions with the MITI: Recommendations for Research and Practice
Scott T. Walters,Malissa Cornett,Amanda M. Vader
Motivational Interviewing : Training, Research, Implementation, Practice , 2012, DOI: 10.5195/mitrip.2012.21
Abstract: This article describes the coding portion of a study to test the effectiveness of a motivational interviewing (MI) training program for probation officers. We describe some of the challenges with using the Motivational Interview Treatment Integrity (MITI) instrument to code interactions between probation officers and clients. Our team of raters was able to obtain adequate inter-rater reliability on most MITI scales, though reliability ratings on some of the specific behavior counts such as Giving Information, MI Adherent, and MI Non-adherent fell considerably lower than the original MITI norming study. Our results suggest that the MITI is a mostly reliable instrument for coding criminal justice interactions, though there were exceptions to this rule. Based on our experiences, we discuss some of the ways that probation interactions might be different from traditional counseling interactions, and identify some rules of thumb that helped us to code interactions. We end with suggestions for how MITI feedback can be used effectively in training and supervision in criminal justice and other non-traditional settings.
Operating Cooperatively (OC) Sensor for Highly Specific Recognition of Nucleic Acids
Evan M. Cornett, Martin R. O’Steen, Dmitry M. Kolpashchikov
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0055919
Abstract: Molecular Beacon (MB) probes have been extensively used for nucleic acid analysis because of their ability to produce fluorescent signal in solution instantly after hybridization. The indirect binding of MB probe to a target analyte offers several advantages, including: improved genotyping accuracy and the possibility to analyse folded nucleic acids. Here we report on a new design for MB-based sensor, called ‘Operating Cooperatively’ (OC), which takes advantage of indirect binding of MB probe to a target analyte. The sensor consists of two unmodified DNA strands, which hybridize to a universal MB probe and a nucleic acid analyte to form a fluorescent complex. OC sensors were designed to analyze two human SNPs and E.coli 16S rRNA. High specificity of the approach was demonstrated by the detection of true analyte in over 100 times excess amount of single base substituted analytes. Taking into account the flexibility in the design and the simplicity in optimization, we conclude that OC sensors may become versatile and efficient tools for instant DNA and RNA analysis in homogeneous solution.
