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 Dec 2003

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

Department of Psychology: Faculty Publications

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 Dec 2003

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 Dec 2003

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 Dec 2003

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 Dec 2003

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

Department of Psychology: Faculty Publications

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 …

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.

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

Microbiology Publications and Other Works

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, …

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 Dec 2003

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 …

Interleukin-10 And Pathogenesis Of Murine Ocular Toxoplasmosis, Fangli Lu, Shiguang Huang, Lloyd H. Kasper Dec 2003

Interleukin-10 And Pathogenesis Of Murine Ocular Toxoplasmosis, Fangli Lu, Shiguang Huang, Lloyd H. Kasper

Dartmouth Scholarship

To understand the role of interleukin-10 (IL-10) in ocular toxoplasmosis, we compared C57BL/6 (B6) and BALB/c background mice lacking a functional IL-10 gene (IL-10(-/-)) and B6 transgenic mice expressing IL-10 under the control of the IL-2 promoter. Increased cellular infiltration and necrosis were observed in the eye tissue of IL-10(-/-) mice of both the B6 and BALB/c backgrounds with associated changes in the levels of cytokines in serum. In contrast, there was no evidence of necrosis in the eye tissue from IL-10 transgenic mice following parasite exposure. Our results demonstrate that IL-10 is important in the regulation of inflammation during …

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 …


Serotonergic Agents And Alcoholism Treatment: A Simulation, Scott F. Stoltenberg Dec 2003

Serotonergic Agents And Alcoholism Treatment: A Simulation, Scott F. Stoltenberg

Department of Psychology: Faculty Publications

Background: Those with early-onset alcoholism may better respond to ondansetron (a 5-HT3 receptor antagonist) than to selective serotonin reuptake inhibitor (SSRI) treatment, whereas those with late-onset alcoholism may present the reverse response pattern. Johnson and colleagues proposed a model that attempts to explain the observed treatment response patterns of those with early and late alcoholism onset by focusing on the influence of a common genetic variant in the serotonin transporter regulatory region (5-HTTLPR) on serotonin (5-HT) and dopamine (DA) system function.
Methods: The present study formalizes and extends Johnson’s descriptive model into a computer simulation consisting of differential equations. For …

Inadequate Physician Knowledge Of The Effects Of Diet On Blood Lipids And Lipoproteins., Mary M. Flynn, Chris N. Sciamanna, Kevin C. Vigilante Dec 2003

Inadequate Physician Knowledge Of The Effects Of Diet On Blood Lipids And Lipoproteins., Mary M. Flynn, Chris N. Sciamanna, Kevin C. Vigilante

College of Population Health Faculty Papers

BACKGROUND:To assess the nutrition knowledge of physicians on the basic effects of diet on blood lipids and lipoproteins.

METHODS:Anonymous mailed dietary knowledge surveys to 6000 randomly selected physicians in the United States licensed in either Internal Medicine or Cardiology.RESULTS:Response rate: 16% (n = 639). Half of the physicians did not know that canola oil and 26% did not know olive oil were good sources of monounsaturated fat. Ninety-three percent (84% of cardiologists vs. 96% of internists; p < 0.001) did not know that a low-fat diet, in general, would increase blood triglycerides. Approximately three-quarters (70% of cardiologists vs. 77% of internists; p < 0.01) did not know a low-fat diet would decrease HDL-c and almost half (45%) thought that a low-fat diet would not change HDL-c.

CONCLUSIONS:If physicians are to implement dietary and cholesterol management guidelines, they will likely need to become more knowledgeable about nutrition.
