Modelling competing risks in nephrology research: an example in peritoneal dialysis [PDF]

open access: yes, 2013
BACKGROUND: Modelling competing risks is an essential issue in Nephrology Research. In peritoneal dialysis studies, sometimes inappropriate methods (i.e.

Chemoresistome mapping in individual breast cancer patients unravels diversity in dynamic transcriptional adaptation

open access: yesMolecular Oncology, EarlyView.
This study used longitudinal transcriptomics and gene‐pattern classification to uncover patient‐specific mechanisms of chemotherapy resistance in breast cancer. Findings reveal preexisting drug‐tolerant states in primary tumors and diverse gene rewiring patterns across patients, converging on a few dysregulated functional modules. Despite receiving the

COMPARISON BETWEEN COMPETING RISKS VIA THE COPULA-GRAPHIC ESTIMATOR COMPARACIÓN ENTRE RIESGOS COMPETITIVOS VÍA EL ESTIMADOR CÓPULA-GRÁFICO

open access: yesRevista Colombiana de Estadística, 2011
The identifiability problem in competing risks associated to the dependence measure between the failure modes, can be solved by means of the copula-graphic estimator which assumes the copula function known. This paper compares, through a simulation study,

Target Trial Emulation Using Hospital-Based Observational Data: Demonstration and Application in COVID-19

open access: yesLife, 2023
Methodological biases are common in observational studies evaluating treatment effectiveness. The objective of this study is to emulate a target trial in a competing risks setting using hospital-based observational data. We extend established methodology

Aberrant expression of nuclear prothymosin α contributes to epithelial‐mesenchymal transition in lung cancer

open access: yesMolecular Oncology, EarlyView.
Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Estimating disease incidence rates and transition probabilities in elderly patients using multi-state models: a case study in fragility fracture using a Bayesian approach

open access: yesBMC Medical Research Methodology, 2023
Background Multi-state models are complex stochastic models which focus on pathways defined by the temporal and sequential occurrence of numerous events of interest.

Landscape of BRAF transcript variants in human cancer

open access: yesMolecular Oncology, EarlyView.
We investigate the annotation of BRAF variants, focusing on protein‐coding BRAF‐220 (formerly BRAF‐reference) and BRAF‐204 (BRAF‐X1). The IsoWorm pipeline allows us to quantify these variants in human cancer, starting from RNA‐sequencing data. BRAF‐204 is more abundant than BRAF‐220 and impacts patient survival.

APPLICATION OF THE RECURRENT DATA ANALYSIS ON FL245 SWITCHES AT INTERCONEXIÓN ELÉCTRICA S.A. APLICACIÓN DEL ANÁLISIS DE DATOS RECURRENTES SOBRE INTERRUPTORES FL245 EN INTERCONEXIÓN ELÉCTRICA S.A.

open access: yesRevista Colombiana de Estadística, 2011
Recurrent data arise when a unit (or group of such units) is monitored over time and a particular event (or group of events) occurs at several points of the observation period, for example, times of recurrent episodes of a disease in patients or times of
