Mental Health Of Incarcerated Juveniles In Nevada: Final Report, Nevada Institute For Children's Rerearch And Policy, University Of Nevada, Las Vegas, Jennifer Petsonius, Denise Tanata, Michelle Chino Dr

Nevada Institute for Children's Research and Policy Reports

The prevalence of mental health problems in the juvenile offender population is substantially higher than that of the general population (Cocozza & Skowyra, 2000). Studies estimate that one in five juvenile offenders has serious mental health problems, which is nearly twice the rate of occurrence of mental illness in children and adults in the general population (NMHA Fact Sheet #l). However, there have been several methodological problems encountered in previous research. These include the use of inconsistent definitions and measurements of mental illness; the use of biased, nonrandom samples, a reliance on retrospective case report data, and the use of …

Barriers To Community Mental Health Services For Latinos: Treatment Considerations, Haig Kouyoumdjian, Byron L. Zamboanga, David J. Hansen

Faculty Publications, Department of Psychology

The underutilization of mental health services by Latinos has been a growing concern in research and clinical practice. This has become increasingly important as the population of Latinos in the United States rapidly rises and the evidence that many are not receiving needed mental health services accumulates. To provide an understanding of the issues, this article provides an overview of risk factors that may influence the mental health of Latinos and examines prevalence rates of psychopathology and service utilization trends. This article then presents a comprehensive review of the socioeconomic, cultural, and psychotherapeutic barriers that prevent Latinos from receiving community …

Uncertainty And The Value Of Diagnostic Information With Application To Axillary Lymph Node Dissection In Breast Cancer, Giovanni Parmigiani

Johns Hopkins University, Dept. of Biostatistics Working Papers

In clinical decision making, it is common to ask whether, and how much, a diagnostic procedure is contributing to subsequent treatment decisions. Statistically, quantification of the value of the information provided by a diagnostic procedure can be carried out using decision trees with multiple decision points, representing both the diagnostic test and the subsequent treatments that may depend on the test's results. This article investigates probabilistic sensitivity analysis approaches for exploring and communicating parameter uncertainty in such decision trees. Complexities arise because uncertainty about a model's inputs determines uncertainty about optimal decisions at all decision nodes of a tree. We …

Survival Model Predictive Accuracy And Roc Curves, Patrick Heagerty, Yingye Zheng

UW Biostatistics Working Paper Series

The predictive accuracy of a survival model can be summarized using extensions of the proportion of variation explained by the model, or R^2, commonly used for continuous response models, or using extensions of sensitivity and specificity which are commonly used for binary response models.

In this manuscript we propose new time-dependent accuracy summaries based on time-specific versions of sensitivity and specificity calculated over risk sets. We connect the accuracy summaries to a previously proposed global concordance measure which is a variant of Kendall's tau. In addition, we show how standard Cox regression output can be used to obtain estimates of …

Semiparametric Estimation Of Time-Dependent: Roc Curves For Longitudinal Marker Data, Yingye Zheng, Patrick Heagerty

UW Biostatistics Working Paper Series

One approach to evaluating the strength of association between a longitudinal marker process and a key clinical event time is through predictive regression methods such as a time-dependent covariate hazard model. For example, a time-varying covariate Cox model specifies the instantaneous risk of the event as a function of the time-varying marker and additional covariates. In this manuscript we explore a second complementary approach which characterizes the distribution of the marker as a function of both the measurement time and the ultimate event time. Our goal is to flexibly extend the standard diagnostic accuracy concepts of sensitivity and specificity to …

Analysis Of End-Of-Life Content In Critical Care Nursing Textbooks, Karin T. Kirchhoff, Renea L. Beckstrand, Prashanth Reddy Anumandla

Faculty Publications

Nurses have identified a need for improving their knowledge and skills in providing end-of-life care. Critical care nursing textbooks can serve as an important source of information on end-of-life care for critical care nurses. Hence, an analysis of end-of-life content in 14 critical care nursing textbooks was conducted. Critical care nursing textbooks used for review were published in 1995 or later and identified from the libraries at the University of Wisconsin-Madison and Brigham Young University. The end-of-life content areas identified by the American Association of Colleges of Nursing (AACN), under which the AACN end-of-life competencies for undergraduate nursing students can …

Sexual Risk Taking In Adolescence: The Role Of Self-Regulation And Attraction To Risk, Marcela Raffaelli, Lisa J. Crockett

Faculty Publications, Department of Psychology

Precursors of adolescent sexual risk taking were examined in a multiethnic sample consisting of 443 children (51% girls) of National Longitudinal Survey of Youth participants. Respondents were 12–13 years old in 1994 and 16–17 in 1998. Controlling for demographic and contextual factors, self-regulation—but not risk proneness—was significantly (modestly) associated with overall sexual risk taking 4 years later, Analyses of individual sexual behaviors indicated that self-regulation may affect choices made after becoming sexually active (e.g. number of partners) rather than the initiation of sexual activity. Measures of parent and peer influence had independent effects on sexual risk taking but did not …

Flavone: The Molecular And Mechanistic Study Of How A Simple Flavonoid Protects Dna From Oxidative Damage., Jennifer Dawn Dean

Electronic Theses and Dissertations

Dietary flavonoids are ubiquitous and are marketed as supplements. Characterized as antioxidants, they offer protection against a number of degenerative diseases. Flavonoid mechanics involve free radical scavenging, metal chelation, and substrate association. The skeletal structure of flavonoids is a fused ring system modified by hydroxyl, sugar, and carbohydrate additions. Flavone is a structurally simple flavonoid. Quercetin and its glycosidic analog rutin are complex structures. Using a DNA oxidation/cleavage assay, flavone reduces DNA nicking by 91%. Depending on the solvent system used, quercetin can either increase or decrease DNA oxidation. Rutin exhibits neither pro- nor antioxidant activity. The molecular interactions responsible …

The Role Of Erp57 In Hras Intracellular Trafficking And Function., Jaime Lyn Parman

Electronic Theses and Dissertations

Ras is a central player in signal transduction that mediates cellular proliferation and differentiation. Recent evidence has shown that lipid and non-lipid modified domains participate in Ras traffic and that plasma membrane association is mediated by vectorial vesicular transport from the endomembrane system. ERp57, an ER chaperone, has been shown to specifically bind farnesylated Hras but not non-farnesylated Hras. The objective of this study was to determine if ERp57 participates in Ras trafficking and function. First, the effect of ERp57 knock down by siRNA technology on Hras function was studied; there was a reduction in ERp57 cellular levels that led …

Identification of those who are victims of domestic violence is important to prevent further abuse and injury. The purpose of this non-experimental study was to determine barriers of Emergency Department Registered Nurses screening patients for domestic violence. 33 ED RNs completed a short anonymous questionnaire that was developed by Dr. Mary Lou Moore, Wake Forrest University, Winston-Salem, North Carolina. The most significant barriers to screening identified, were the lack of education on how to ask questions about abuse, language barriers, …

Tolerance Of The Fetus By The Maternal Immune System: Role Of Inflammatory Mediators At The Feto-Maternal Interface, Colette Kanellopoulos-Langevin, Stephane M. Caucheteux, Philippe Verbeke, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

The adaptive immune system of placental mammals has evolved to tolerate the fetus. Rejection of the fetus by adaptive immune responses is therefore a rare event, with abortion being caused more frequently by inflammation in the placenta. This review will cover recent aspects of immune privilege and the innate immune system at the feto-maternal interface, citing examples of the role played by microbial infections in fetal demise.

The Relation Of Dietary Patterns To Future Survival, Health, And Cardiovascular Events In Older Adults, Paula Diehr

Paula Diehr

BACKGROUND: There have been few long-term follow-up studies of older adults who follow different dietary patterns. METHODS: We cluster-analyzed data on dietary fat, fiber, protein, carbohydrate, and calorie consumption from the U.S. Cardiovascular Health Study (mean age=73), and examined the relationship of the dietary clusters to outcomes 10 years later. RESULTS: The five clusters were named "Healthy diet" (relatively high in fiber and carbohydrate and low in fat), "Unhealthy diet" (relatively high in protein and fat, relatively low in carbohydrates and fiber); "High Calorie," "Low Calorie," and "Low 4," which was distinguished by higher alcohol consumption. The clusters were strongly …

Optimization Of Breast Cancer Screening Modalities, Yu Shen, Giovanni Parmigiani

Johns Hopkins University, Dept. of Biostatistics Working Papers

Mathematical models and decision analyses based on microsimulations have been shown to be useful in evaluating relative merits of various screening strategies in terms of cost and mortality reduction. Most investigations regarding the balance between mortality reduction and costs have focused on a single modality, mammography. A systematic evaluation of the relative expenses and projected benefit of combining clinical breast examination and mammography is not at present available. The purpose of this report is to provide methodologic details including assumptions and data used in the process of modeling for complex decision analyses, when searching for optimal breast cancer screening strategies …

Modeling The Incubation Period Of Anthrax, Ron Brookmeyer, Elizabeth Johnson, Sarah Barry

Johns Hopkins University, Dept. of Biostatistics Working Papers

Models of the incubation period of anthrax are important to public health planners because they can be used to predict the delay before outbreaks are detected, the size of an outbreak and the duration of time that persons should remain on antibiotics to prevent disease. The difficulty is that there is little direct data about the incubation period in humans. The objective of this paper is to develop and apply models for the incubation period of anthrax. Mechanistic models that account for the biology of spore clearance and germination are developed based on a competing risks formulation. The models predict …

Linda Lê : Schizo-Positive?, Isabelle Favre

Présence Francophone: Revue internationale de langue et de littérature

In her novel entitled "Calomnies", Linda Lê depicts a "mad uncle" and a young female writer fascinated with her uncle’s marginality. In this book, Lê presents a complex view of schizophrenia. Sometimes, the actions and thoughts of the uncle are reminiscent of Deleuze and Guattari’s concepts such as le corps sans organe and la machine célibataire. Some other times however, Lê pays attention to the past of the uncle and shows how, in Vietnam, he witnessed the hypocrisy of his family during the war. These passages are then closer to Laing’s theories, since the environment and conditions in which he …

Cd43 Modulates Severity And Onset Of Experimental Autoimmune Encephalomyelitis., Thandi M. Onami, M. L. Ford, A. Sperling, R. Ahmed, B. D. Evavold

Thandi M. Onami

Experimental autoimmune encephalomyelitis (EAE) is a mouse model of multiple sclerosis characterized by infiltration of activated CD4(+) T lymphocytes into tissues of the CNS. This study investigated the role of CD43 in the induction and progression of EAE. Results demonstrate that CD43-deficient mice have reduced and delayed clinical and histological disease severity relative to CD43(+/+) mice. This reduction was characterized by decreased CD4(+) T cell infiltration of the CNS of CD43(-/-) mice but similar numbers of Ag-specific T cells in the periphery, suggesting a defect in T cell trafficking to the CNS. The absence of CD43 also affected cytokine production, …

High School Students' Attitudes About Firearms Policies, Katherine A. Vittes, Susan B. Sorenson, Dennis Gilbert

Departmental Papers (SPP)

Purpose: To examine high school students’ attitudes about firearm policies and to compare their attitudes with those of adults.

Methods: The Hamilton Youth and Guns Poll is the first national survey of high school students about their attitudes concerning firearm policies. Questions were asked of 1005 sophomores, juniors, and seniors about their actual (i.e., direct) exposure (e.g., presence of a gun in the home) and about their social (i.e., indirect) exposure (e.g., whether the student could get a gun) to firearms and related violence. Population weights were applied, and multivariate logistic regression was used to examine the relationship …

Determinants Of Satisfaction With An Automated Alcohol Evaluation Program., Daniel Z Lieberman

Psychiatry and Behavioral Sciences Faculty Publications

High rates of untreated mental illness cause serious health problems in the United States and worldwide. The use of computer-administered therapy has the potential to increase access to mental health care for certain patient populations. An online version of an alcohol check-up was developed that guided subjects through a series of standardized questionnaires, and provided them with feedback designed to enhance their appreciation of the negative aspects of their alcohol use. Ratings of the helpfulness of the questionnaires were evaluated in order to determine the characteristics of individuals who would potentially benefit from an automated substance abuse intervention, and to …

Effect Of Background Synaptic Activity On Excitatory-Postsynaptic Potential-Spike Coupling, Veronika Zsiros

Theses and Dissertations (ETD)

Neurons receive large amount of synaptic inputs in vivo, which may impact the coupling between EPSPs and spikes. We mimicked the in vivo synaptic activity of the cell with the dynamic clamp system. We recorded from pyramidal cells in neocortical slices in vitro to investigate how timing and probability of spike generation in response to an EPSP is affected by background synaptic conductance under these conditions. We found that near threshold, background synaptic conductance improved the precision of spike timing by reducing the depolarization-related prolongation of the EPSP. In cells with ongoing spike activity and background synaptic conductances, an …
