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 …

Computational Techniques For Spatial Logistic Regression With Large Datasets, Christopher J. Paciorek, Louise Ryan

Harvard University Biostatistics Working Paper Series

In epidemiological work, outcomes are frequently non-normal, sample sizes may be large, and effects are often small. To relate health outcomes to geographic risk factors, fast and powerful methods for fitting spatial models, particularly for non-normal data, are required. We focus on binary outcomes, with the risk surface a smooth function of space. We compare penalized likelihood models, including the penalized quasi-likelihood (PQL) approach, and Bayesian models based on fit, speed, and ease of implementation.

A Bayesian model using a spectral basis representation of the spatial surface provides the best tradeoff of sensitivity and specificity in simulations, detecting real spatial …

Estimation And Projection Of Indicence And Prevalence Based On Doubly Truncated Data With Application To Pharmacoepidemiological Databases, Henrik Stovring, Mei-Cheng Wang

Johns Hopkins University, Dept. of Biostatistics Working Papers

Incidences of disease are of primary interest in any epidemiological analysis of disease spread in general populations. Ordinary estimates obtained from follow-up of an initially non-diseased cohort are costly, and so such estimates are not routinely available. In contrast, routine registers exist for many diseases with data on all detected cases within a given calendar time period, but lacking information on non-diseased. In the present work we show how this type of data supplemented with data on the past birth process can be analyzed to yield age specific incidence estimates as well as lifetime prevalence. A non-parametric model is studied …

Is The Number Of Sick Persons In A Cohort Constant Over Time?, Paula Diehr, Ann Derleth, Anne Newman, Liming Cai

UW Biostatistics Working Paper Series

Objectives: To estimate the number of persons in a cohort who are sick, over time.

Methods: We calculated the number of sick persons in the Cardiovascular Health Study (CHS), a cohort study of older adults followed up to 14 years, using eight definitions of “healthy” and “sick”. We projected the number in each health state over time for a birth cohort.

Results: The number of sick persons in CHS was approximately constant for 14 years, for all definitions of “sick”. The estimated number of sick persons in the birth cohort was approximately constant from ages 55-75, after which it decreased. …

People Living With, Not Dying From Disease: Patient Empowerment Through Anti-Retroviral Therapy And Possibilities For Social Change, Xin Wei Ngiam

Independent Study Project (ISP) Collection

In South Africa today, it is estimated that there are 6.5 million people living with HIV/AIDS, at least half a million of whom require urgent treatment. On the continent of Africa as a whole the numbers are even more startling. Unfortunately, although the South African government has now committed itself to rolling out anti-retroviral therapy through the public healthcare system, progress has been slower than expected. Yet in numerous sites around South Africa, rollout centres have been established successfully, even in the most rural parts of the country. These programmes rely on existing community initiatives, community health workers and volunteers, …

A Preliminary Test Of A Student-Centered Intervention On Increasing Physical Activity In Underserved Adolescents, Dawn K. Wilson, Alexandra E. Evans, Joel Williams, Gary Mixon, John R. Sirard, Russell R. Pate

Faculty Publications

Background - Previous studies have shown that choice and self-initiated behavior changes are important for increasing intrinsic motivation and physical activity (PA), however, little of this research has focused on underserved adolescents.

Purpose - This study examined the effects of a 4-week student-centered intervention on increasing PA in underserved adolescents.

Methods - Twenty-eight students in the intervention school were matched (on race, percentage on free or reduced-price lunch program, gender, and age) with 20 students from another school who served as the comparison group (30 girls, 18 boys; ages 10-12 years; 83% African American; 83% on free or reduced-price lunch). …

El Vih En La Ciudad De Buenos Aires: Obstáculos En El Acceso Al Tratamiento En El Sector Público, Erica Tai-Le Bliss

Independent Study Project (ISP) Collection

The focus of my research is the access to HIV treatment in the public health sector in Buenos Aires. HIV testing and treatment are guaranteed, by law, financed completely by the government for patients in the public health sector who do not have any private insurance or social work insurance plan. Over three quarters of the registered cases of HIV are patients in the public sector. Although health care is free in the Capital, many patients don’t take HIV tests, seek treatment or eventually stop taking their medication. To investigate the motivations of the patients, I interviewed three sectors that …

Evaluation Of African-American And White Racial Classification In A Surveillance, Epidemiology, And End Results Cancer Registry, Diva A. Patel, Alicia Knowles, Ann G. Schwartz, Kendra Schwartz

FMPHS Faculty Publications

Objectives: This study evaluated the validity of registry-reported race for individuals who participated in research studies conducted since 1980 through the Metropolitan Detroit Cancer Surveillance System (MDCSS), a Surveillance, Epidemiology, and End Results (SEER) Program registry.

Methods: 5329 individuals who self-identified as African American or White and were classified in the MDCSS registry as African American or White were included. Self-identified and registry-reported race were compared, and associations between demographics and racial misclassification were examined.

Results: Most self-identified African Americans and Whites were correctly classified (sensitivity= 98.5%, specificity=99.7%). Males were two times more likely to be misclassified than females [odds …
