White matter tracts

description: Recent developments in magnetic resonance imaging (MRI) provide an in vivo and noninvasive tool for studying the human brain. In particular, the detection of anisotropic diffusion in biological tissues provides the foundation for diffusion-weighted imaging (DWI), an MRI modality. This modality opens new opportunities for discoveries of the brain's structural connections. Clinically, DWI is often used to analyze white matter tracts to understand neuropsychiatric disorders and the connectivity of the central nervous system. However, due to imaging time required, DWI used in clinical studies has a low angular resolution. In this dissertation, we aim to accurately track and segment the white matter tracts and estimate more representative models from low angular DWI. We first present a novel geodesic approach to segmentation of white matter tracts from diffusion tensor imaging (DTI), estimated from DWI. Geodesic approaches treat the geometry of brain white matter as a manifold, often using the inverse tensor field as a Riemannian metric. The white matter pathways are then inferred from the resulting geodesics. A serious drawback of current geodesic methods is that geodesics tend to deviate from the major eigenvectors in high-curvature areas in order to achieve the shortest path. We propose a method for learning an adaptive Riemannian metric from the DTI data, where the resulting geodesics more closely follow the principal eigenvector of the diffusion tensors even in high-curvature regions. Using the computed geodesics, we develop an automatic way to compute binary segmentations of the white matter tracts. We demonstrate that our method is robust to noise and results in improved geodesics and segmentations. Then, based on binary segmentations, we present a novel Bayesian approach for fractional segmentation of white matter tracts and simultaneous estimation of a multitensor diffusion model. By incorporating a prior that assumes the tensor fields inside each tract are spatially correlated, we are able to reliably estimate multiple tensor compartments in fiber crossing regions, even with low angular diffusion-weighted imaging. This reduces the effects of partial voluming and achieves a more reliable analysis of diffusion measurements.

description: Introduction: Sudden infant death syndrome is a major cause of post-neonatal death in several countries. The aim of our study was to evaluate the carers knowledge and compliance regarding international recommendations for the prevention of sudden infant death syndrome. Methods: Observational, transversal and analytical study through the analysis of anonymous survey applied to pregnant women and carers of children followed in a Family Health Unit. Results: Of 163 eligible carers, 60 were included in the study. The mother filled out the survey in 51 (85%) cases. Sixteen (27%) carers had no previous knowledge on this matter, one (2%) disclosed smoking in the baby household or room and 41 (68%) placed the baby to sleep in supine position. Families with mothers over 30 years old (p = 0.043), with employed parents (p = 0.026) or with undergraduate diploma (father p = 0.016, mother p = 0.006) placed the baby to sleep in supine position. When the mother was unemployed, she more frequently shared the bed with the baby (p = 0.047). Overheating was a concern when the parents had better education (father p = 0.021, mother p = 0.031). Discussion: Younger parents, unemployed or with lower educational status did not follow the recommendations for the prevention of sudden infant death syndrome. Efforts should be done in order to raise awareness on sudden infant death syndrome.

Medication error

description: Medication errors are a problem in the United States healthcare system.  Many patients are harmed unnecessarily, costing billions of dollars annually. The  Institute of Medicine has recommended several strategies for healthcare  institutions to potentially decrease medication errors. Medication reconciliation  was one such recommendation with the aim of helping to eliminate medication  errors.  Medication reconciliation is a process whereby a patient's drug regimen is  reviewed by a healthcare professional for appropriateness and screened for  potential problems that can cause harm. The list is also compared to new orders  written for the patient to ensure the list is accurate and up to date. The Joint  Commission requires the medication reconciliation process be conducted at all  points of patient care transition, including admission, transfer, and discharge in  the hospital setting.  The process of conducting discharge medication reconciliation may  require additional staffing. Additional positions necessitate resources that may  not always be readily available. Such staffing could generate potential revenue if  a patient's discharge prescriptions were filled at the outpatient pharmacy during  the discharge medication reconciliation process. This study evaluated the  potential revenue from maximizing the number of discharge patients who fill their  discharge prescriptions at the outpatient pharmacy. A breakeven analysis was conducted to determine the point at which the costs of new pharmacist and  pharmacy technician positions could reasonably be offset from the estimated  revenues of filling discharge prescriptions.  The results of this study found that at least one new full-time pharmacist  and pharmacy technician position could be created for Monday through Friday  from 0800 to 1630 to provide additional hospital units with discharge pharmacy  services. In addition, a 50% pharmacist and pharmacy technician position could  be created to offer these services in the evening for Monday through Friday from  1631 to 2100, and a 40% pharmacist and pharmacy technician position could be  created for Saturday through Sunday from 0800 to 1530 to provide discharge  pharmacy services. Therefore, if maximization of the number of filled discharge  prescriptions can be achieved, part of the cost of additional staff required for  medication reconciliation may be offset in a positive manner.
Using available data to predict in-hospital cardiopulmonary arrest

description: The main motivation for this investigation was to determine if a reliable predictive model of cardiopulmonary arrest could be developed to serve as the basis of a computerized alerting tool. The alerting tool would be used prospectively in clinical practice, so the underlying predictive model could only use computerized data available at the time of patient care. Such an alerting tool would target appropriate patients for do-not-attempt resuscitation (DNAR) discussions.  A retrospective matched-case control study was performed. A total of 6956 patients (1446 cases and 5510 controls) who were seen as inpatients at Latter Day Saints (LDS) Hospital during the years 1997-2000 were included in this study. Case patients included those who received a response to a code blue call and/or experienced asystole. Asystole is defined as absence of contractions of the heart.  Data were collected on outcome, patient demographics and various clinical findings including clinically relevant vital signs and laboratory results and many nursing observations. All possible predictors were retrieved from LDS Hospital's electronic medical record.  In bivariate tests, age, all vitals signs analyzed, all laboratory findings analyzed and most nursing observations analyzed were significantly associated with cardiopulmonary arrest. Three multivariate models were developed: one using logistic regression techniques and two using artificial neural network techniques. The logistic regression model offered the most discrimination with an area under the receiver operating characteristic curve of 0.863.  Many factors are independently associated with experiencing cardiopulmonary arrest. Also, reliable predictive models of in-hospital cardiopulmonary arrest can be achieved using data exclusively from an existing electronic medical record. The predictive model produced by this work is part of a larger plan to improve DNAR ordering at LDS Hospital. Computerized alerts will be generated for high-risk patients, targeting them for DNAR discussion. The alert application has great potential to increase appropriate cardiopulmonary resuscitation (CPR), improve health care outcomes, decrease costs and improve patient and family satisfaction.

description: Branched wiring networks are interconnections of wires that provide for the  connection of dc and RF (Radio Frequency) components in an aircraft or other type of  apparatus or structure. If by age or by mechanical means the wiring network develops a  wiring fault such as bare wire, it can cause fire or other types of emergencies which may  cause the loss of life and or property.  A Steepest Descent Method is applied to the determination of the topology of a  network of branched wires from the Time Domain Reflectometry (TDR) response of the  network. Inversion theory is used to derive the equations necessary for the Steepest  Descent Method. Functional Spaces are explained, and the properties of the Hilbert  Space are used in the minimization of the Misfit Functional. A computer algorithm is  written taking into account all a priori information so as to speed the process of finding  the wire topology map.  The method works reasonably well if the data are perfect (no noise). With the  addition of noise the algorithm needs to be modified. Noise causes the impedance values  to spread, making the determination of characteristic impedance more problematic.

description: Controlling intracellular localization of proteins to alter their function offers great  potential for treatment of diseases caused due to mislocalization, as well as regulating  cellular functions. Mislocalization of proteins is manifested in diseases ranging from  cancer to metabolic disorders. In this study localization controllable constructs capable of  changing localization on ligand induction were designed and optimized for efficiency of  translocation. These constructs contain a nuclear export signal (NES), a nuclear  localization signal (NLS) and a ligand binding domain (LBD). The constructs localize in  the cytoplasm in the absence of ligand and translocate to the nucleus on ligand induction.  The mechanism of nuclear export of the localization controllable constructs was  studied and it was established that the classical nuclear export receptor Crml is involved  in export of these constructs. Further, the cytoplasmic retention of glucocorticoid and  progesterone receptors was investigated. The results indicated that GR and PR LBDs  were involved in cytoplasmic retention of these receptors via Hsp90.  Finally, controllable protein constructs for regulating localization of oncogene  Bcr-Abl were constructed and tested. The Bcr-Abl fusion protein is causative agent for  chronic myelogenous leukemia (CML). It is predominantly localized in the cytoplasm  initiating signal transduction pathways involved in cell-proliferation and anti-apoptosis.  However, nuclear localization of Bcr-Abl results in apoptosis. Localization controllable  Bcr-Abl protein constructs were tested in human leukemia cell line (K562). These constructs localized in the cytoplasm in the absence of ligand, however, showed varied  localization pattern on addition of ligand depending on the presence/absence of actin  binding domain (ABD). The localization controllable Bcr-Abl constructs were unable to  induce apoptosis either due to inactivation of certain critical domains or due to their  inability to drive an adequate amount of Bcr-Abl into the nucleus necessary for apoptosis.  Further investigation is required to constructs and test localization controllable versions  of Bcr-Abl and its domains capable of inducing apoptosis in regular CML cells, as well  as cells resistant to current standard treatment therapies.  In summary, this dissertation explores the possibility of manipulating NES, NLS  and LBD to construct regulatable protein constructs for correcting intracellular  localization of mislocalized proteins and altering their functionality.

Development of the new best information algorithm for a medical expert system (Iliad)
Creators: name: Guo, Di
Publisher: name: University of Utah
Year: 2012
Subjects: Medical Informatics

description: Iliad is a diagnostic expert system for internal medicine. One important feature that Iliad offers is the ability to analyze a particular patient case and to determine the most cost-effective findings to pursue next at any stage of a work-up. The best information"" algorithm combines an information content calculation together with a cost factor. The calculations then provide a rank-ordering of the alternative patient findings according to cost-effectiveness.  This dissertation presents a three-part study to evaluate the performance of different best information algorithms. In the first two parts of the study the suggestions about the next best data elements to pursue from different algorithms were collected for different vignettes. The performance of different algorithms was compared based on the judgments provided by expert clinicians. The results indicated that the current Iliad information content model could be improved by using a version of Shannon information content model.  The third part of the study evaluated different best information algorithms by a simulation approach. The results indicated that two types of diagnostic behaviors could be simulated. The first type of behavior was characterized by pursuing more history and physical examination findings, less laboratory tests, less expensive work-ups, and more steps to solve a patient case. The second type of behavior was characterized by pursuing less history and physical examination findings, more laboratory tests, more expensive work-ups, and less steps to solve a patient case. The Shannon information content model accomplished work-ups that were significantly less costly than work-ups performed by the current LR (likelihood ratio) information content model. However, the Shannon model required additional computational resources and more history and physical examination steps than the LR model. Decisions regarding the implementation of alternative models require a balance of the relative merits of cost, steps, expert preference, and other important factors.""

Mathematical models of chromosome motility during mitosis

description: Cell division is a complex process that involves carefully orchestrated chemical and mechanical events. Tight regulation is vital during division, since a breakdown in control mechanisms can lead to serious disorders such as cancer. A key step in division is the movement of chromosomes to specific locations in the cell with remarkable precision. In higher eukaryotes, the movement of chromosomes has been well observed over the course of hundreds of years. Yet, the mechanisms underlying chromosome motility and the control of precise chromosome localizations in the cell are poorly understood. More recently, a wealth of experimental data has become available for bacterial division. Despite the long supported theory that bacteria and eukaryotes differ widely when undergoing division, it  is emerging that similar mechanisms for motility and cell cycle control might be at play in both cell types. Mathematical modeling is useful in the study of these dynamic cellular environments, where it is difficult to experimentally uncover the mechanisms that drive  a multitude of mechanical and chemical events. In this dissertation, we develop various mathematical models that address the question of how dynamic polymers can move large objects such as chromosomes in higher eukaryotes and in bacteria. Then, we develop models  that address how chemical and mechanical signals can be coordinated to control the precise localization of a chromosome. The mathematical models proposed here employ stochastic differential equations, ordinary differential equations and partial differential equations. The models are numerically simulated to obtain solutions for various parameter values, but we also use tools from bifurcation theory, asymptotic and perturbation methods for our model analysis. Our mathematical models can not only reproduce the experimental data at hand, but also make predictions about the mechanisms underlying chromosome motility in dividing cells.

description: Issues of social justice continue to permeate all aspects of life in the United States. Acknowledging recent calls for racial justice, as well as efforts to restrict what is taught in mathematics classrooms, researchers and practitioners are increasingly exploring the promises of teaching mathematics for social justice in secondary mathematics classrooms. This dissertation contributes to research about how a social justice mathematics course can be utilized in teacher education programs to support prospective mathematics teachers’ (PMTs’) development of their mathematics identities, as well as how PMTs translate social justice mathematics theory into practice with their secondary mathematics students. This research complexifies the role of primarily white mathematics teachers and teacher educators working toward teaching mathematics for social justice by foregrounding some of the ways in which social justice mathematics curricula and instruction may continue to center whiteness.
 This dissertation includes three studies focused on the design and delivery of a social justice mathematics course offered to undergraduate students, as well as the learning outcomes for 11 PMTs enrolled in the first iteration. As such, each study is formatted for submission to a research journal and contains its own questions, methods, findings, discussion, and conclusion.
 The first and second studies detail the experiences of PMTs in a social justice mathematics course. In the first study, I explored how engaging in such a course contributed to PMTs’ mathematics identities. Findings in this case study suggest that sustained engagement with social justice mathematics can contribute to PMTs’ conceptions of mathematics and encourage them to address issues of social justice in their mathematics classrooms. Building on this, three of the PMTs enrolled in the course and I engaged in a critical participatory action research study to investigate their experiences working toward teaching mathematics for social justice in their secondary mathematics field placements. Prior to engaging their students with social justice mathematics tasks, the PMTs focused on developing relationships and trust with students and also maintained a commitment to engaging students with dominant mathematics.
 Informed by a finding in the first study (i.e., PMTs continued to view mathematics as objective and neutral), in the third study, I investigated the prominence of whiteness in the development and facilitation of the course. Using action research and critical whiteness studies, I detail areas in which I perpetuated whiteness, as well as areas in which I began to make progress.

description: Much of the current nursing research is based upon the assumption that admission to a hospital is a distressing experience.  These studies generally employ a clinical experimental method in which reduction of distress is achieved through a warm,   personalized nursing approach. Measurements of systolic blood pressure,   radial pulse,   oral temperature and respiratory rate have been commonly used as an index of nursing effectiveness in reducing patient distress.  The patient sample in this study consisted of 54 Eskimo, Aleut and Athapaskan patients who were admitted over a three month period for elective medical and surgical conditions. The purpose of the study was to measure the influence of a psychiatric nursing approach upon the reduction of emotional distress during hospital admission of Alaska native patients. The experimental group received a warm,   personalized approach from the psychiatric nurse who attempted to identify and respond to patient feelings about hospitalization. The control group received the routine admission from the hospital staff with the assumption that admission procedures in a large hospital are often task-oriented, hurried and impersonal. Pre and post admission measures of systolic and diastolic blood pressure,   radial pulse,   oral temperature and respiratory rate were used as indices of emotional distress.  A post admission interview was conducted by an independent observer to determine patient feelings about admission.    It was hypothesized that Alaskan patients receiving a personalized nursing approach as part of the hospital admission procedure would experience greater reduction in their vital sign measures and greater relief from their emotional distress than patients receiving a less personal approach. It was further expected that the group difference in vital sign decrease would reflect a difference in the amount of emotional stress reduction.  Results indicated no significant difference between the experimental and control groups in the five vital sign measures. This indicated that the experimental psychiatric nursing approach was no more effective in reducing patient distress than the routine admission administered by the hospital staff,   at least from the vital sign measures. Post admission interview results concurred with the statistical findings.

description: Dieser Bericht befasst sich mit der Abschätzung des Messunsicherheitsbeitrags durch Quantisierung bei digital anzeigenden Messgeräten mit dem Ziel, Quantisierungsvorgänge auf Basis der verfügbaren Informationen optimal zu beschreiben, und diese Informationen einfach in der Praxis anzuwenden. Er soll Hinweise geben neben der üblichen Betrachtung des Unsicherheitseinflusses der Ablesbarkeit der letzten dargestellten Stelle (Digit) eines Anzeigewertes als Rechteckverteilung innerhalb der Grenzen aR = ±0,5 Digit den Quantisierungsvorgang unter technischen Gesichtspunkten besser zu beschreiben. Die Analyse der Messunsicherheit eines digital anzeigenden Messgerätes zeigt schließlich, dass es sinnvoll ist, für den Vorgang des gesamten Messvorgangs eine Dreieck-Verteilungsdichte anzusetzen, und zwar mit der Breite 2aD zweier Quantisierungsschritte (Codesprüngen). Damit erhält man eine kombinierte Standardabweichung (kombinierte Standardunsicherheit) óD = uMU(UKombD) = 2aD ∙0,41. Wenn stattdessen als Näherung die Normalverteilung anstelle der Dreieckverteilung angenommen würde, wäre die kombinierte Standardmessunsicherheit etwas zu groß abgeschätzt. Für diesen Fall ist die Standardabweichung óN = uMU(UKombN) = 2aN ∙ 0,5 (bei einer Überdeckungswahrscheinlichkeit von 95 %), wieder mit einer Breite der Verteilung 2aN von zwei Quantisierungsschritten. Dieser Bericht soll als eine alternative Betrachtung zu in der Praxis vertretenen Methoden beim Umgang mit Quantisierungsprozessen (bzw. Rundungen) und weniger als verbindliche Vorgehensweise oder Ersatz bisheriger Abschätzungen verstanden werden.

description: Granular diamond composites are particulate reinforced composites, where the particulate phase is a grade of high-hardness polycrystalline diamond, embedded in a tougher, hard-material matrix. Granular diamond composites are hierarchically-structured materials. In addition to the macrostructure and microstructure, granular diamond composites have a mesostructure that encompasses the morphology of the matrix and granules and is characterized by parameters such as component volume fraction, granular sphericity, and matrix uniformity. The mesostructure is functionally designed to improve the performance of the composite in petroleum well-drilling applications by increasing the fracture resistance while maintaining the wear resistance. The impact of the mesostructure on the flexural strength, wear resistance, impact resistance, and in-field performance was measured. Physical testing showed that volume fraction of the tougher, matrix phase can be increased significantly before the wear resistance of the composite decreases appreciably. But the testing also showed that the method developed to produce the composites resulted in component materials with inferior properties. The flexural strength of a polycrystalline-diamond/tungsten-carbide material system was explored using several modeling techniques, including analytic, two-dimensional numeric, and three-dimensional numeric models. Residual stresses, arising from the change in conditions after the material is formed in a high-temperature, high-pressure sintering process, have a significant impact on the calculated strength of the composite. Dilatational residual stresses have never been treated in a rigorous manner in the literature and are often neglected completely. In this study, the thermal and dilatational residual stresses were modeled. Stresses from externally applied loads preferentially concentrate in the stiffer diamond phase. Thermal residual stresses strengthen the stiffer and weaker diamond phase through residual compression and weaken the carbide phase through residual tension. The dilatational residual stresses partially counteract the thermal residual stresses. Without thermal residual stresses the composite would have lower strength due to premature failure in the diamond phase. Without dilatational residual stresses the composite would have lower strength due to premature failure in the carbide phase. The strengths predicted by the enhanced models match the measured strengths quite well, despite significant uncertainty in the material properties and process parameters.

description: This report deals with the estimation of the measurement uncertainty contribution by way of quantisation for digitally indicating measuring instruments. Its aim is to describe quantisation processes in the best possible way based on the available information, and to make use of this information in practice. In addition to the usual consideration of the uncertainty influence of the readability of the last digit of a display value as a rectangular distribution within the limits of aR = ±0.5 Digit, this report is intended to provide information to better describe the quantisation process from a technical point of view. The profound analysis of the measurement uncertainty of a digitally indicating measuring device shows that it makes sense to apply a triangular distribution density with a width 2aD of two quantisation steps (code jumps) for the entire measurement process. This yields a combined standard deviation (combined standard uncertainty) σD = uMU(dUKombD) = 2aD ∙ 0.41. Assuming a normal distribution instead of a triangular distribution as an approximation, the estimated combined standard measurement uncertainty would be slightly too large. For this case, the standard deviation is σN = uMU(dUKombN) = 2aN ∙ 0.5 (with a coverage probability of 95 %), again with a width of distribution 2aN of two quantisation steps. This report represents a kind of alternative approach or consideration to the methods used in practice when dealing with quantisation processes (or rounding). It is not so much to be understood as a binding procedure or replacement of previous estimates.

description: Nursesâ€™ awareness of legal issues was assessed in this study.  The dependant variable, legal knowledge was represented by malpractice, standard of care, liability, negligence, suit-prone situations, and res ipsa loquitur doctrine.  The independent variables were a) sex,  b) age, c) education, d) clinical experience, and e) previous legal experience or inservice.  The level of legal knowledge was determined through a previously designed case study questionnaire.  The questionnaire was administered to a random sample of 40 full-time registered nurses and Womanâ€™s Hospital of Acadiana in Lafayette, Louisiana.  A 93% completion rate was achieved.  The returned questionnaires were scored according to answers marked correctly.  The question evaluated represented an overall total score as well as a score per individual legal category.  The independent and dependent variables were compiled and tabulated according to descriptive parameters.  The overall total score of the legal questionnaire suggest that staff nurses have a basic understanding of legal issues.  The legal topic categories of standard of care, liability, suit-prone situations, and res ipsa loquitur doctrine still require additional understanding.  Additional observation was that nurses were relatively young and recent graduates (within three to five years) of Nursing; programs.  Overall, the younger nurses scored highest on the questionnaire.  The independent an dependent variables were tested by correlation coefficients and noted to have no statistical significance at the .05 level.

Telaugis aenescens Burmeister 1844: 337
Note. Two presently recognized subspecies of Telaugis aenescens have been described, one of which occurs in the research area. The other one is T. aenescens subandina Soula, 1998 (recorded from Bolivia, Colombia, Ecuador, Peru).
Subspecies Telaugis aenescens aenescens Burmeister, 1844
Telaugis aenescens Burmeister 1844: 337 (French Guiana - NEOTYPE)
Distribution. Guyana: Soula 2002b: 19. Suriname: Ohaus 1934: 150; Blackwelder 1944: 241; Machatschke 1972: 70; MHCN; NZCS; RMNH. French Guiana: Ohaus 1934: 150; Blackwelder 1944: 241; Soula 1998: 97 (designation NEOTYPE Telaugis aenescens), 2010a: 58; RMNH. Brazil (NA): Ohaus 1934: 150 (NA); Blackwelder 1944: 241; Soula 1998: 97. Venezuela: Soula 2002b: 19. Other: Burmeister 1844: 337 (Mexico).
Note 1. Burmeister (1844: 337) gives the type locality of Telaugis aenescens as Mexico, but subsequently (Burmeister 1855: 516) rectifies this by retracting the mention of Mexico and replacing it with Suriname.
Note 2. Soula (1998: 97) records Telaugis aenescens aenescens for French Guiana and Brazil and states that the species is “sans doute présente dans les trois Guyanes et au Venezuela,” but he provides no records or references regarding the presence of this species in Suriname, Guyana or Venezuela. Soula (2002b: 19) records the species for Guyana and Venezuela but not for French Guiana or Brazil. Because the occcurrence of this species in French Guiana and Brazil is corroborated by other authors and we are unaware of any other records from Guyana or Venezuela, we suspect that Soula’s records from the latter countries are erroneous. Given the proximity of these countries to the known area of distribution, we consider the possible occurrence of the species in Guyana and Venezuela in need of confirmation.

description: This dissertation describes the total synthesis of the marine ladder toxin brevenal utilizing a convergent synthetic strategy. Critical to the success of this work was the use of olefinic-ester cyclization reactions and the utilization of glycal epoxides as precursors to C-C and C-H bonds. Previous total syntheses of brevenal and our strategy for the completion of the molecule are discussed in detail.  In addition, olefinic-lactone cyclization reactions that result in the generation of macrocycles are described. The methodology was used to synthesize the natural  products muscone and muscopyridine.
