Factors Related To Delayed Time For Hiv Care Among Youth Living With Hiv: A Cross-Sectional Analysis Of Social Support Networks And Access To Care, Patricia L. Jones

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: This research explored the pattern of influence social support networks had on delayed time between diagnosis and first doctor’s visit after diagnosis of HIV in youth. Results showed that factors related to receiving a referral were prosocial peer behaviors and excessive fibbing in the past 6 months. The study identified sources of social support and described the relationship between the source of support and time of first doctor’s visit after HIV diagnosis. Both descriptive and multivariate analyses were performed on all youth (N=347) and specifically on those seeking care. Methodology: Historical data were extracted from the baseline dataset of …

Chaotic Desynchronization Of Multistrain Diseases, Ira Schwartz, Leah Shaw, Derek Cummings, Lora Billings, Marie Mccrary, Donald Burke

Department of Mathematics Faculty Scholarship and Creative Works

Multistrain diseases are diseases that consist of several strains, or serotypes. The serotypes may interact by antibody-dependent enhancement rADE, in which infection with a single serotype is asymptomatic, but infection with a second serotype leads to serious illness accompanied by greater infectivity. It has been observed from serotype data of dengue hemorrhagic fever that outbreaks of the four serotypes occur asynchronously. Both autonomous and seasonally driven outbreaks were studied in a model containing ADE. For sufficiently small ADE, the number of infectives of each serotype synchronizes, with outbreaks occurring in phase. When the ADE increases past a threshold, the system …

Are Specific Language Impairment And Dyslexia Distinct Disorders?, Hugh W. Catts, Suzanne M. Adlof, Tiffany Hogan, Susan Ellis Weismer

Faculty Publications

Purpose - The purpose of this study was to determine whether specific language impairment (SLI) and dyslexia are distinct developmental disorders.

Method - Study 1 investigated the overlap between SLI identified in kindergarten and dyslexia identified in 2nd, 4th, or 8th grades in a representative sample of 527 children. Study 2 examined phonological processing in a subsample of participants, including 21 children with dyslexia only, and 43 children with SLI only, 18 children with SLI and dyslexia, and 165 children with typical language/reading development.

Sources Of Variation In Nutrient Intakes Among Men In Shanghai, China, Hui Cai, Gong Yang, Yong-Bing Xiang, James R. Hébert, Da-Ke Liu, Wei Zheng, Xiao-Ou Shu

Faculty Publications

Background and objective: Random errors, from any source, will attenuate epidemiological risk estimates. Before we launched the Shanghai Men’s Health Study (SMHS), a large population-based cohort study investigating the diet–cancer association among Chinese men, a dietary calibration study was conducted among 96 men aged 40–75 years (mean age 56.5 years), with biweekly 24-hour dietary recalls (24HDRs) implemented over a 1-year period. Data from this study were analysed to evaluate the nature and magnitude of variances for intake of 26 nutrients among SMHS participants, to compare variance ratios of 26 nutrients among Chinese men and women and individuals in other studies, …

Intimate Partner Violence And Disabilities Among Women Attending Family Practice Clinics, Ann L. Coker, Paige H. Smith, Mary Kay Fadden

CRVAW Faculty Journal Articles

Purpose: To estimate the frequency and type of disabilities preventing work among those experiencing intimate partner violence (IPV) compared with those never experiencing IPV.

Methods: We used a large cross-sectional survey of women, ages 18–65, attending family practice clinics from 1997 through 1998. Participation included a 5–10-minute in-clinic survey assessing IPV experience and a longer telephone survey assessing health status and chronic disabilities that prevented work outside the home or housework.

Results: Of 1,152 eligible women surveyed, 54% experienced some type of IPV, and 24% were currently in a violent relationship. Women who had ever experienced IPV …

Medicare Advantage Snps: A New Opportunity For Integrated Care?, Christie Provost Peters

National Health Policy Forum

Medicare Advantage special needs plans (SNPs) are a new type of coordinated care plan established by the Medicare Prescription Drug, Improvement and Modernization Act. SNPs were created to encourage greater access to Medicare managed care for certain special needs populations: the institutionalized, persons dually eligible for Medicare and Medicaid, and the chronically ill. Some view SNPs as a new opportunity to integrate acute and long-term care services as well as Medicare and Medicaid financing. Others, however, question the degree to which full integration will become a widespread reality. This issue brief examines the SNP option and the promises and challenges …

Pratiques Cliniques Des Physiothérapeutes Dans Le Traitement De Travailleurs Souffrant De Maux De Dos Aigus Et Subaigus, Régis Blais, Stéphane Poitras, Bonnie Swaine, Michel Rossignol

Rapports de recherche scientifique

Les maux de dos représentent une part importante des lésions indemnisées par la Commission de la Santé et Sécurité du Travail du Québec (CSST). Les physiothérapeutes sont couramment engagés dans la prise en charge de ce problème, mais on ne peut évaluer l'efficacité de leur approche thérapeutique puisqu'on en connaît mal la constitution.

Ce projet visait principalement à 1) décrire prospectivement les interventions pratiquées par les physiothérapeutes auprès de travailleurs indemnisés par la CSST suite à un mal de dos aigu ou subaigu et 2) identifier les facteurs associés à ces choix d'interventions.

Une enquête prospective a été réalisée auprès …

Dump Truck Driver Crushed Between Trackhoe And Dump Truck, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Motor Vehicle

On November 11, 2004, a 33-year-old male dump truck driver died when he was crushed between the driver’s side of the dump truck and the swinging counter-weight of an excavator (trackhoe). His dump truck became stuck in mud after the trackhoe loaded dirt into it so he walked to the on-site office and informed the owner. The owner located a bulldozer on site and drove it to the dump truck while the driver retrieved a chain from his personal pickup truck. The owner raised the blade so the driver could attach the chain to it. Raising the blade of the …

Population Intervention Models In Causal Inference, Alan E. Hubbard, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

Marginal structural models (MSM) provide a powerful tool for estimating the causal effect of a] treatment variable or risk variable on the distribution of a disease in a population. These models, as originally introduced by Robins (e.g., Robins (2000a), Robins (2000b), van der Laan and Robins (2002)), model the marginal distributions of treatment-specific counterfactual outcomes, possibly conditional on a subset of the baseline covariates, and its dependence on treatment. Marginal structural models are particularly useful in the context of longitudinal data structures, in which each subject's treatment and covariate history are measured over time, and an outcome is recorded at …

Additive Hazards Models With Latent Treatment Effectiveness Lag Time, Ying Qing Chen, Charles A. Rohde, Mei-Cheng Wang

Johns Hopkins University, Dept. of Biostatistics Working Papers

In many clinical trials to evaluate treatment efficacy, it is believed that there may exist latent treatment effectiveness lag times after which medical procedure or chemical compound would be in full effect. In this article, semiparametric regression models are proposed and studied to estimate the treatment effect accounting for such latent lag times. The new models take advantage of the invariance property of the additive hazards model in marginalizing over random effects, so parameters in the models are easy to be estimated and interpreted, while the flexibility without specifying baseline hazard function is kept. Monte Carlo simulation studies demonstrate the …

Gauss-Seidel Estimation Of Generalized Linear Mixed Models With Application To Poisson Modeling Of Spatially Varying Disease Rates, Subharup Guha, Louise Ryan

Harvard University Biostatistics Working Paper Series

Generalized linear mixed models (GLMMs) provide an elegant framework for the analysis of correlated data. Due to the non-closed form of the likelihood, GLMMs are often fit by computational procedures like penalized quasi-likelihood (PQL). Special cases of these models are generalized linear models (GLMs), which are often fit using algorithms like iterative weighted least squares (IWLS). High computational costs and memory space constraints often make it difficult to apply these iterative procedures to data sets with very large number of cases.

This paper proposes a computationally efficient strategy based on the Gauss-Seidel algorithm that iteratively fits sub-models of the GLMM …
