Laboratory Reporting Of Tuberculosis Test Results And Patient Treatment Initiation In California, Lisa Pascopella, Steffi Kellam, John Ridderhof, Daniel P. Chin, Arthur Reingold, Edward Desmond, Jennifer Flood, Sarah Royce

Public and Community Health Sciences Faculty Publications

Prompt laboratory reporting of tuberculosis (TB) test results is necessary for TB control. To understand the extent of and factors contributing to laboratory reporting delays and the impact of reporting delays on initiation of treatment of TB patients, we analyzed data from 300 consecutive culture-positive TB cases reported in four California counties in 1998. Laboratory reporting to the specimen submitter was delayed for 26.9% of smear-positive patients and 46.8% of smear-negative patients. Delays were associated with the type of laboratory that performed the testing and with delayed transport of specimens. Referral laboratories (public health and commercial) had longer median reporting …

Cultural Value Orientations, Attributions, And Breast Cancer Screening Behaviors, Patricia M. Flynn

Loma Linda University Electronic Theses, Dissertations & Projects

Discrepancies in breast cancer screening behavior exist among various ethnic groups in the United States (Jacobs & Lauderdale, 2001), with Latino American women reporting particularly low screening rates in comparison to Anglo American women (ACS, 2002). Research indicates that behavior is in part influenced by aspects of culture and relevant psychological processes (Betancourt & Lopez, 1993; Betancourt & Fuentes, 2001). This study was designed to investigate the relations among cultural values, attributional processes, and breast cancer screening behavior among Anglo and Latino women. This study also investigated the influence of acculturation among Latino women in relation to the other study …

Pediatric Obesity: Intervention Outcomes, Kristy Anne Kuehfuss

Loma Linda University Electronic Theses, Dissertations & Projects

Childhood obesity is a national epidemic with serious medical and psychological implications. Almost one-fourth of children in the United States are overweight.

A Hierarchical Multivariate Two-Part Model For Profiling Providers' Effects On Healthcare Charges, John W. Robinson, Scott L. Zeger, Christopher B. Forrest

Johns Hopkins University, Dept. of Biostatistics Working Papers

Procedures for analyzing and comparing healthcare providers' effects on health services delivery and outcomes have been referred to as provider profiling. In a typical profiling procedure, patient-level responses are measured for clusters of patients treated by providers that in turn, can be regarded as statistically exchangeable. Thus, a hierarchical model naturally represents the structure of the data. When provider effects on multiple responses are profiled, a multivariate model rather than a series of univariate models, can capture associations among responses at both the provider and patient levels. When responses are in the form of charges for healthcare services and sampled …

Estimation Of Direct And Indirect Causal Effects In Longitudinal Studies, Mark J. Van Der Laan, Maya L. Petersen

U.C. Berkeley Division of Biostatistics Working Paper Series

The causal effect of a treatment on an outcome is generally mediated by several intermediate variables. Estimation of the component of the causal effect of a treatment that is mediated by a given intermediate variable (the indirect effect of the treatment), and the component that is not mediated by that intermediate variable (the direct effect of the treatment) is often relevant to mechanistic understanding and to the design of clinical and public health interventions. Under the assumption of no-unmeasured confounders, Robins & Greenland (1992) and Pearl (2000), develop two identifiability results for direct and indirect causal effects. They define an …

Development Of A Safe Neutralization Assay For Sars-Cov And Characterization Of S-Glycoprotein, Dong P. Han, Hyung G. Kim, Young B. Kim, Michael W. Cho

Faculty Scholarship

The etiological agent of severe acute respiratory syndrome (SARS) has been identified as a novel coronavirus SARS-CoV. Similar to other coronaviruses, spike (S)-glycoprotein of the virus interacts with a cellular receptor and mediates membrane fusion to allow viral entry into susceptible target cells. Accordingly, S-protein plays an important role in virus infection cycle and is the primary target of neutralizing antibodies. To begin to understand its biochemical and immunological properties, we expressed both full-length and ectodomain of the protein in various primate cells. Our results show that the protein has an electrophoretic mobility of about 160–170 kDa. The protein is …

Quality Of Life In The Chronically Mentally Ill: Impact Of Demographics, Symptomatology, And Coping Styles, Dawn Castner

All-Inclusive List of Electronic Theses and Dissertations

Schizophrenia and schizoaffective disorder are often persistent and disabling conditions that require a wide range ofbiopsychosocial treatments. In recent decades, treatment has largely focused on assisting persons to maintain community tenure, while little attention has been devoted to quality of life. For many, these illnesses have a negative impact on life satisfaction due to their chronic and variable nature, lack of completely efficacious treatments, and social stigma. Some have speculated that various demographic, symptom, or treatment variables influence quality of life, but the nature and amount of influence is uncertain. 111 The purpose of this study was to investigate the …

Episodic Heavy Drinking And Marijuana Use Among Undergraduate Students At Western Kentucky University, Ariel L. Sarmiento

Masters Theses & Specialist Projects

Research has documented that Episodic Heavy Drinking (EHD), defined as consuming four or more and five or more alcoholic drinks per drinking episode among females and males, respectively, is a prevalent risk behavior among undergraduate college students throughout the United States. Moreover, studies have shown that EHD is the leading cause of preventable morbidity and mortality among college students as unintentional injuries, sexual assaults, and unsafe sexual behaviors among this population have been linked to this risk behavior.

Illicit substance use, although often portrayed as a separate risk behavior, is also associated with EHD. Nationally, the most frequently used illicit …

The aging of the nation’s population will create a surge in the need for long-term care services, putting pressure on existing funding sources and fueling demand for more. This paper examines one financing option—private long-term care insurance—and summarizes its brief history and the several critical precedents that have influenced the products as currently sold. Other topics discussed include the challenges to encouraging sales growth as well as increasing the role of this type of insurance in paying for long-term care.

Non-Parametric Estimation Of Roc Curves In The Absence Of A Gold Standard, Xiao-Hua Zhou, Pete Castelluccio, Chuan Zhou

UW Biostatistics Working Paper Series

In evaluation of diagnostic accuracy of tests, a gold standard on the disease status is required. However, in many complex diseases, it is impossible or unethical to obtain such the gold standard. If an imperfect standard is used as if it were a gold standard, the estimated accuracy of the tests would be biased. This type of bias is called imperfect gold standard bias. In this paper we develop a maximum likelihood (ML) method for estimating ROC curves and their areas of ordinal-scale tests in the absence of a gold standard. Our simulation study shows the proposed estimates for the …

Ozone And Mortality: A Meta-Analysis Of Time-Series Studies And Comparison To A Multi-City Study (The National Morbidity, Mortality, And Air Pollution Study), Michelle L. Bell, Jonathan M. Samet, Francesca Dominici

Johns Hopkins University, Dept. of Biostatistics Working Papers

While many time-series studies of ozone and daily mortality identified positive associations,others yielded null or inconclusive results. We performed a meta-analysis of 144 effect estimates from 39 time-series studies, and estimated pooled effects by lags, age groups,cause-specific mortality, and concentration metrics. We compared results to estimates from the National Morbidity, Mortality, and Air Pollution Study (NMMAPS), a time-series study of 95 large U.S. cities from 1987 to 2000. Both meta-analysis and NMMAPS results provided strong evidence of a short-term association between ozone and mortality, with larger effects for cardiovascular and respiratory mortality, the elderly, and current day ozone exposure as …
