Surrogate Screening Models For The Low Physical Activity Criterion Of Frailty, Sandrah P. Eckel, Karen Bandeen-Roche, Paulo H.M. Chaves, Linda P. Fried, Thomas A. Louis

Johns Hopkins University, Dept. of Biostatistics Working Papers

Background and Aims. Low physical activity, one of five criteria in a validated clinical phenotype of frailty, is assessed by a standardized questionnaire on up to 20 leisure time activities. Because of the time demanded to collect the interview data, it has been challenging to translate to studies other than the Cardiovascular Health Study (CHS), for which it was developed. Considering subsets of activities, we identified and evaluated streamlined surrogate assessment methods and compared them to one implemented in the Women’s Health and Aging Study (WHAS).

Methods. Using data on men and women ages 65 and older from the CHS, …

BACKGROUND: Scale up of paediatric antiretroviral therapy in resource limited settings continues despite limited access to routine laboratory monitoring. We documented the weight and height responses in HIV infected Ugandan children on highly active antiretroviral therapy and determined clinical factors associated with successful treatment outcomes.

METHODS: A prospective cohort of HIV infected children were initiated on HAART and followed for 48 weeks. Body mass index for age z scores(BAZ), weight and height-for-age z scores (WAZ & HAZ) were calculated: CD4 cell % and HIV-1 RNA were measured at baseline and every 12 weeks. Treatment outcomes were classified according to; both …

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, & …

Contextualizing The Health Belief Model And The Social Epidemiology Theories In The Study Of Aids In Malawi, Kumbirai Madondo

All Theses

The association between HIV/AIDS knowledge, risk perception and risky sexual behavior remains a valuable area of study among scholars seeking to understand the AIDS epidemic in Africa. Past research has focused only on either the Health Belief Model or social epidemiology ideas to understand AIDS but never combined the two. The current study is unique and adds to the body of knowledge by making use of both the Health Belief Model and social epidemiology ideas to understand these relationships more clearly and, more importantly, to explore the role that keeping AIDS a secret has in the contexts of risk perception, …

The Development And Use Of A Geographic Information System For Evaluating The Association Between Pesticide Exposure And Prostate Cancer, Kristen Wells

Theses and Dissertations

Abstract 1 – A Geographic Information System for Evaluating Residential Pesticide Exposure and Prostate Cancer Incidence Agricultural pesticide exposure is hypothesized to be a risk factor for prostate cancer, and such exposures are of particular concern for men living in farming communities where large-scale pesticide applications occur. Prostate cancer incidence data were obtained from the State Health Registry of Iowa for the years 1996 through 2006, and county and census tract level age-adjusted incidence rates were calculated. Historical crop-specific land use records and pesticide sales data for the state of Iowa during 1990 were integrated into a geographic information system …

Plasma Prekallikrein Levels Are Positively Associated With Circulating Lipid Levels And The Metabolic Syndrome In Children., James A. Mackenzie, Kristen A. Roosa, Brooks B. Gump, Amy K. Dumas, Kestutis G. Bendinskas

Falk College Research Center

Plasma prekallikrein (PK) has been shown to be associated with cardiovascular disease (CVD) and its risk factors, but these associations have not been investigated in children. The present study examined PK activity in relation to well-established cardiovascular risk factors in a cohort of children aged 9–11 years (N = 97). We found a significant and positive association between PK and fasting levels of total cholesterol (p < 0.01), non-high-density lipoprotein cholesterol (p < 0.01), and triglycerides (p < 0.001). In addition, there was a significant association between PK activity and the metabolic syndrome, a clustering of risk factors considered to have an impact on atherosclerosis and CVD mortality. Finally, we found that children with a family history of CVD had significantly elevated PK activity. These novel findings warrant further investigations into the relationship between circulating PK levels and CVD risk factors because PK may be involved in the progression of the disease state. Il est bien connu que la pre´kallicre´ine (PK) est associe´e a` la maladie cardiovasculaire (CVD) et a` ses facteurs de risque, mais ces associations n’ont pas e´te´ ve´rifie´es chez les enfants. Cette e´tude se propose de ve´rifier l’association entre l’activite´ de la PK et les facteurs de risque de CVD aupre`s d’une cohorte d’enfants aˆge´s de 9 a` 11 ans (N = 97). On observe une corre´lation positive significative entre la PK et les variables suivantes : la concentration totale de choleste´rol a` jeun (p < 0,01), les concentrations des lipoprote´ines non a` haute densite´ (p < 0,01) et la concentration des triglyce´rides (p < 0,001). De plus, on observe une corre´lation significative entre l’activite´ de la PK et le syndrome me´tabolique constitue par un ensemble de facteurs ayant un effet sur l’athe´roscle´rose et la mortalite´ due a` la CVD. En dernier lieu, les enfants avec des ante´ce´dents familiaux de CVD pre´sentent une plus importante activite´ de la PK, et ce, de fac¸on significative. Ces premie`res observations sugge`rent d’autres e´tudes sur la relation entre la concentration sanguine de PK et les facteurs de risque de CVD, car la PK pourrait eˆtre implique´e dans la progression de la maladi

Aids Epidemic In The Russian Federation And Policy Reform, Veronika Kiselev

Independent Study Project (ISP) Collection

The AIDS epidemic in the Russian Federation has been a constant struggle for the government and the population since the early 90’s. The epidemic is the most rapidly growing epidemic of HIV/AIDS seen in history and has caused much international attention. The epidemic coinciding with the fall of the Soviet Union and the transition of the Russian government from socialist to democratic state has had a huge impact on the policy and government actions to fight the epidemic. The financial struggles that hit a large portion of the population as a result of the fall of the Soviet Union caused …

Gender, Germs, And Dirt: A Case Study Of Properly Politicised Science, Sharyn Clough

XIV IAPh Symposium 2010

This presentation is part of the Feminist Perspectives in the Sciences: Epidemiology track.

The relatively recent increase in cases of allergies and asthma, especially in industrialised nations of the north and west, has been explained by the “hygiene hypothesis”—viz., that increased cleanliness and sanitation have unintended negative consequences for immune health—an hypothesis that has received robust epidemiological support (e.g., Platts-Mills 2002). Over the last few years, support for the hypothesis has increased with the discovery that populations regularly exposed to certain parasitic worms (helminths) have very low incidence of chronic inflammatory diseases such as Crohn’s (Elliot, Summers, and Weinstock 2007). …

Association Between Obesity, Depression, And Inflammation Among Seventh-Day Adventists In The Biopsychosocial Religion And Health Study, Michael Paalani

Loma Linda University Electronic Theses, Dissertations & Projects

The effects of obesity and depression on morbidity and mortality may be mediated by inflammatory processes. Homeostasis within the immune system depends on a balance of pro-inflammatory and anti-inflammatory cytokine molecules, so chronic inflammatory diseases may result from cytokine dysregulation. The target population consisted of 508 Seventh Day Adventists (SDAs) who participated in the Biopsychosocial Religion and Health Study (BHRS), a sub-study of the Adventist Health Study-2. The study was a cross-sectional analysis of the association between obesity, depression, and inflammation after controlling for demographic, socioeconomic, health behavioral, and health status variables among BHRS participants.

Obesity was assessed by body …

The Association Between Teen Parenthood And Marital Status Among Women, Amy Feinberg

The purpose of this study was to (1) develop a culturally relevant and organizationally appropriate mechanism for the collection of comprehensive client histories and (2) to provide the opportunity for staff to engage in a new process of developing and implementing data collection strategies. As a result of the use of a community-based participatory approach, (1) a missed opportunity for program evaluation and development was identified, …

A Qualitative Approach To Explore The Experiences Of Health Care Providers Who Treat Patients For Post Traumatic Stress Disorder (Ptsd), Mark Killebrew

Theses and Dissertations

Post Traumatic Stress Disorder (PTSD) is an anxiety disorder that occurs when people are exposed to stressful, life-threatening experiences. Consequently, after exposure to such an event, many people may experience fear, guilt, or anger and may believe the trauma is reoccurring. According to the National Institute of Mental Health, approximately 5.2 million U.S. adults age 18-54 have PTSD in any given year. The prevalence of PTSD is even more problematic within the military where an estimated 30% of those who have spent time in war zones experiences PTSD. Researchers have been examining the impact of veterans’ PTSD symptoms on family …

Statin Use And The Risk Of Clostridium Difficile In Academic Medical Centers: A Matched Case Control Study, Christine Motzkus

Theses and Dissertations

BACKGROUND: Increasing rates of hospital acquired Clostridium difficile (CDI), as well as mortality owing to CDI, warrants further exploration of risk factors. Clostridium difficile bacteria typically produce toxins which inactivate the Rho proteins found in the colonic epithelium. Statins also disrupt Rho protein cell signaling functions. The objective of this study was to estimate the extent to which use of statins increases the risk of healthcare-acquired CDI. METHODS: Patients over 18 years of age admitted to hospitals contributing data to the University HealthSystem Consortium between 2002 and 2009 were eligible. We identified 25, 111 incident cases of CDI and matched …

The Relationship Between Treatment-Seeking And Characteristics Of Depression Among African Americans, Tamara Scott

Theses and Dissertations

Objective: Depression is a common psychiatric condition, and despite the availability of effective treatments, this condition is largely under-recognized and undertreated, particularly among African Americans. One reason for this discrepancy may be that depressive symptoms often co-occur with physical health conditions, which can influence both the reporting of depressive symptomology, willingness to seek care, and the type of healthcare provider sought. The purpose of this study was to explore the relationship between treatment-seeking characteristics and diagnostic attributions of depression among community-dwelling African American adults. Methods: Data come from the National Survey of American Life, a nationally representative sample of African …

Strategies For Deriving A Single Measure Of The Overall Burden Of Antimicrobial Resistance In Hospitals, Alessandro Orlando

Theses and Dissertations

Background: Antimicrobial-resistant infections result in hospital stays costing between $18,000 and $29,000. As of 2009, Centers for Medicare and Medicaid Services no longer upgrade payments for hospital-acquired infections. Hospital epidemiologists monitor and document rates of individual resistant microbes in antibiogram reports. Overall summary measures capturing resistance within a hospital may be useful. Objectives: We applied four techniques (L1- and L2-principal component analysis (PCA), desirability functions, and simple summary) to create summary measures of resistance and described the four summary measures with respect to reliability, proportion of variance explained, and clinical utility. Methods: We requested antibiograms from hospitals participating in the …

The Effect Of Medicaid Policy Reform On Dental Utilization Rates For Children, Matthew Winheim

Theses and Dissertations

Background: Regular access to dental services is a well-known factor in the oral health and development of children.1 As such, the United States federal government mandates each state to include dental services for children enrolled in Medicaid through the age of 21. Despite this mandate, the utilization rate of dental services among Medicaid enrolled children has remained remarkably low.2 In July 2005, Virginia implemented a sweeping Medicaid policy reform titled “Smiles for Children,” specifically aiming to increase Medicaid pediatric dental utilization rates. The purpose of this study aims to assess the effect of this 2005 policy reform on the utilization …

Nonmedical Prescription Drug Use On College Campuses: Risk Factors For Abuse, Jennifer Barber

Theses and Dissertations

Background: In recent years, there has been an increase in prescription drug abuse, particularly among adolescents and young adults. While substance abuse on college campuses has remained a pervasive public health concern, rates of nonmedical prescription drug use surpass commonly abused drugs. The three most commonly abused prescription drugs (central nervous system (CNS) depressants, opioids, and stimulants) were assessed to identify differences among student characteristics, as well as their relationship with abuse. Purpose: The purpose of this study is to conduct a secondary analysis to explore demographic variables (race, gender, academic performance, living arrangement, alcohol and other drug usage, and …
