Direct Effect Models, Mark J. Van Der Laan, Maya L. Petersen Aug 2005

Direct Effect Models, 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 for treatment and the intermediate variable, Robins & Greenland (1992) define an individual direct effect as the counterfactual effect of …

Clinical Preventive Services: When Is The Juice Worth The Squeeze?, Eileen Salinsky

National Health Policy Forum

This paper provides an overview of clinical preventive services, including a definition of such services and the role of the U.S. Preventive Services Task Force in recommending which services should be routinely offered to patients. It also describes efforts to analyze the cost effectiveness of clinical preventive services and reviews the insurance coverage policies of private and public payers. Barriers to increased uptake of appropriate services are discussed and policy relevant issues are summarized.


Dynamic Effects Of Antibody-Dependent Enhancement On The Fitness Of Viruses, Derek Cummings, Ira Schwartz, Lora Billings, Leah Shaw, Donald Burke Aug 2005

Dynamic Effects Of Antibody-Dependent Enhancement On The Fitness Of Viruses, Derek Cummings, Ira Schwartz, Lora Billings, Leah Shaw, Donald Burke

Department of Mathematics Faculty Scholarship and Creative Works

Antibody-dependent enhancement (ADE), a phenomenon in which viral replication is increased rather than decreased by immune sera, has been observed in vitro for a large number of viruses of public health importance, including flaviviruses, coronaviruses, and retroviruses. The most striking in vivo example of ADE in humans is dengue hemorrhagic fever, a disease in which ADE is thought to increase the severity of clinical manifestations of dengue virus infection by increasing virus replication. We examine the epidemiological impact of ADE on the prevalence and persistence of viral serotypes. Using a dynamical system model of n cocirculating dengue serotypes, we find …

Caring For "Ryan White": The Fundamentals Of Hiv/Aids Treatment Policy, Jessamyn Taylor Aug 2005

Caring For "Ryan White": The Fundamentals Of Hiv/Aids Treatment Policy, Jessamyn Taylor

National Health Policy Forum

This background paper provides an overview of the HIV/ AIDS epidemic in the United States and discusses how treatment of the disease and the populations most affected by it have changed over time. The federal government’s domestic and global efforts in prevention, research, and treatment of the disease are highlighted. The paper outlines the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act, a set of programs that fund treatment services for uninsured and underinsured individuals living with HIV/AIDS, and places it in the context of other federal programs that fund treatment for HIV/AIDS. Policy issues for Ryan White’s potential congressional …


Exposure To Volatile Organic Compounds And Effect On Neurobehavioral Function., Abhijeet Jagannath Bhanegaonkar Aug 2005

Exposure To Volatile Organic Compounds And Effect On Neurobehavioral Function., Abhijeet Jagannath Bhanegaonkar

Electronic Theses and Dissertations

Data of 1338 respondents from the Priority Toxicant Reference Range Study were analyzed to examine exposure to volatile organic compounds (VOCs). Self-reported contact to chemical products and blood concentrations of specific chemicals were analyzed. Neurobehavioral function was assessed by simple reaction time test (SRTT), symbol digit substitution test (SDST), and serial digit learning test (SDLT). Prevalence of exposure to VOC products was, for instance, air freshener/room deodorant - 34.7%, gasoline - 29.2%, finger nail polish - 16.2%, and diesel fuel/ kerosene - 10.6%. The 95th percentiles of blood VOCs (μg/L) were calculated for 41 chemicals including Benzene - 0.476, 1,1,1-Trichloroethane …
