Subsidized Housing, Public Housing, And Adolescent Violence And Substance Use, Tamara Leech

Department of Public Health Scholarship and Creative Works

This study examines the separate relationships of public housing residents and subsidized housing residence to adolescent health risk behavior. Data included 2,530 adolescents aged 14 to 19 who were children of the National the Longitudinal Study of Youth. The author uses stratified propensity methods to compare the behaviors of each group—subsidized housing residents and public housing residents—to a matched control group of teens receiving no housing assistance. The results reveal no significant relationship between public housing residence and violence, heavy alcohol/marijuana use, or other drug use. However, subsidized housing residents have significantly lower rates of violence and hard drug use, …

Implications Of Lifecourse Epidemiology For Research On Determinants Of Adult Disease, Sze Yan Liu, Richard N. Jones, M. Maria Glamour

Department of Public Health Scholarship and Creative Works

Many diseases commonly associated with aging are now thought to have social and physiologic antecedents in early life. Understanding how the timing of exposure to early life risk factors influences later-life health may illuminate mechanisms driving adult health inequalities and identify possible points for effective interventions. Recognizing chronic diseases as developing across the life course also has implications for the conduct of research on adult risk factors for disease. We review alternative conceptual models that describe how the timing of risk factor exposure relates to the development of disease. We propose some expansions of lifecourse models to improve their relevance …

Distribution Of Health Care Expenditures For Hiv-Infected Patients, Ray Y. Chen, Neil A. Accortt, Andrew O. Westfall, Michael J. Mugavero, James L. Raper, Gretchen A. Cloud, Beth K. Stone, Jerome Carter, Stephanie Call, Maria Pisu, Jeroan J. Allison, Michael S. Saag

BACKGROUND: Health care expenditures for persons infected with human immunodeficiency virus (HIV) in the United State determined on the basis of actual health care use have not been reported in the era of highly active antiretroviral therapy.

METHODS: Patients receiving primary care at the University of Alabama at Birmingham HIV clinic were included in the study. All encounters (except emergency room visits) that occurred within the University of Alabama at Birmingham Hospital System from 1 March 2000 to 1 March 2001 were analyzed. Medication expenditures were determined on the basis of 2001 average wholesale price. Hospitalization expenditures were determined on …

Trends In Aids-Defining And Non-Aids-Defining Malignancies Among Hiv-Infected Patients: 1989-2002, Roger Bedimo, Ray Y. Chen, Neil A. Accortt, James L. Raper, Carol Linn, Jeroan J. Allison, John Dubay, Michael S. Saag, Craig J. Hoesley

Jeroan J. Allison

In a comparison of rates of acquired immunodeficiency syndrome (AIDS)-defining malignancies (ADMs) for 1989-1996 versus 1997-2002, we found a decrease in ADMs (rate ratio, 0.31; P<.0001) and a significant increase in non-AIDS-defining malignancies (non-ADMs; rate ratio, 10.87; P<.0002). The mean CD4 cell count was lower among patients with ADMs than among those with non-ADMs. A longer duration of survival during highly active antiretroviral therapy might explain the increasing incidence of non-ADMs.

The Role Of Unrealistic Optimism In Explaining Preventive Behaviors In High Versus Low Endemic Malaria Settings In Belize, Daniel G. Handysides

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Of all the diseases an individual can encounter in the world, malaria is one of the most destructive. Simple measures like sleeping under a bednet would greatly reduce the burden (Abeku, 2007). When people estimate their risk relative to others, they are most often unrealistically optimistic, which may explain why those at risk often fail to perform behaviors, such as using a bednet that will reduce their risk. However, one study showed that people at high risk for malaria held pessimistic perceptions of their risk for the disease, but the reasons for this finding are unclear (Morrison, Ager, & …

The Impact Of The Stent Era On The Management Strategy For Acute Myocardial Infarction: A Population-Based Perspective, Harold Dauerman, Robert Goldberg, Jorge Yarzebski, Darleen Lessard, Joel Gore

Jorge L. Yarzebski

We determined trends in the use of invasive diagnostic and revascularization strategies from a multihospital community-wide perspective for patients suffering acute myocardial infarction (AMI). Comparing 3,824 patients treated in the prestent era (1986-1993) to 1,915 patients hospitalized during the stent era (1995-1997), there was a significant increase in the use of invasive procedures and revascularization techniques across a broad spectrum of AMI patients during their index hospitalization. This resulted in a higher-risk profile of patients referred for invasive management of AMI in the stent era. Cathet. Cardiovasc. Intervent. 51:255-258, 2000.

Jorge L. Yarzebski

Factors associated with delay to hospital arrival after the onset of symptoms suggestive of acute myocardial infarction (AMI) were examined in the late 1960s and 1970s, but recent data concerning these characteristics are limited. The purpose of the present study was to examine overall and temporal distributions of the extent of patients' delay from the time of onset of AMI symptoms to hospital arrival and factors associated with delay in seeking medical care from a multihospital, population-based perspective. Review of medical records was undertaken of patients hospitalized with a discharge diagnosis of AMI in 16 teaching and community hospitals in …

Erroneous Measurement Of Intracranial Pressure Caused By Simultaneous Ventricular Drainage: A Hydrodynamic Model Study, H. Wilkinson, Jorge Yarzebski, E. Wilkinson, Frederick Anderson

Jorge L. Yarzebski

Intracranial pressure (ICP) is often measured from intraventricular catheters, a technique that allows therapeutic drainage of ventricular cerebrospinal fluid (CSF) as an aid in controlling ICP and circumventing obstruction. Drainage of CSF simultaneously with ongoing ICP measurement has been advocated as safe and efficient, and devices are commercially available to permit this practice; however, this concept has been seriously challenged, based on clinical observations. The inaccuracy induced by simultaneous CSF drainage and ICP monitoring is quantitated in this report in a mechanical brain model using a standard ventricular catheter. The following conclusions have been confirmed: 1) rapid CSF drainage induces …
