Bayesian Profile Regression to Deal With Multiple Highly Correlated Exposures and a Censored Survival Outcome. First Application in Ionizing Radiation Epidemiology

Autor: Marion Belloni, Olivier Laurent, Chantal Guihenneuc, Sophie Ancelet

Publikováno v: Frontiers in Public Health, Vol 8 (2020)

As multifactorial and chronic diseases, cancers are among these pathologies for which the exposome concept is essential to gain more insight into the associated etiology and, ultimately, lead to better primary prevention strategies for public health.

Shared and unshared exposure measurement error in occupational cohort studies and their effects on statistical inference in proportional hazards models.

Autor: Sabine Hoffmann, Dominique Laurier, Estelle Rage, Chantal Guihenneuc, Sophie Ancelet

Publikováno v: PLoS ONE, Vol 13, Iss 2, p e0190792 (2018)

Exposure measurement error represents one of the most important sources of uncertainty in epidemiology. When exposure uncertainty is not or only poorly accounted for, it can lead to biased risk estimates and a distortion of the shape of the exposure-

New insights into handling missing values in environmental epidemiological studies.

Autor: Célina Roda, Ioannis Nicolis, Isabelle Momas, Chantal Guihenneuc

Publikováno v: PLoS ONE, Vol 9, Iss 9, p e104254 (2014)

Missing data are unavoidable in environmental epidemiologic surveys. The aim of this study was to compare methods for handling large amounts of missing values: omission of missing values, single and multiple imputations (through linear regression or

A Bayesian hierarchical approach to account for left-censored and missing radiation doses prone to classical measurement error when analyzing lung cancer mortality due to γ-ray exposure in the French cohort of uranium miners

Epidemiological data on cohorts of occupationally exposed uranium miners are currently used to assess health risks associated with chronic exposure to low doses of ionizing radiation. Nevertheless, exposure uncertainty is ubiquitous and questions the

Citrulline (CIT) is an endogenous amino acid produced by the intestine. Recent literature has consistently shown CIT to be an activator of muscle protein synthesis (MPS). However, the underlying mechanism is still unknown. Our working hypothesis was
