1. Risk of hypothermia in a new olympic event: the 10-km marathon swim
INTRODUCTION: There are no available data addressing the potential clinical risks of open-water swimming competitions. OBJECTIVE: Address the risks of hypothermia and hypoglycemia during a 10-km open-water swimming competition in order to alert physicians to the potential dangers of this recently-introduced Olympic event. METHODS: This was an observational c

2. Modelos de sobrevivência com fração de cura e erro de medida nas covariáveis
In this work, we study the survival cure rate model proposed by Yakovlev et al. (1993), based on a competing risks structure concurring to cause the event of interest, and the approach proposed by Chen et al. (1999), where covariates are introduced to model the risk amount. We focus the measurement error covariates topics, considering the use of corrected sc

3. Modelos de sobrevivência de longa-duração : uma abordagem unificada
Em análise de sobrevivência, determinados estudos caracterizam-se por apresentar uma fração significativa de sobreviventes, ou seja, pacientes em tratamento que não apresentaram o evento de interesse, mesmo após um longo período de acompanhamento. Assim considerar modelos de sobrevivência usuais, que assumem que a função de sobrevivência converge

4. Um estudo de caso sobre os resultados da implantação da manufatura enxuta e impactos nos metodos de analise de investimentos / A study of case on the results of the implantation of the lean manufacturing and impacts in the methods of analysis investments
As mudanças nos padrões de competitividade da indústria brasileira influenciaram os procedimentos na avaliação de investimentos em capital fixo das empresas. Neste sentido, a decisão de investir em determinado projeto não é baseada somente na relação entre uma taxa interna de retomo e uma taxa mínima de atratividade, mas deve-se levar em considera

7. Dose-response curves and competing risks.
Points of the underlying dose-response curve of a lethal response or group of lethal responses induced by varying doses of a toxicant in a homogeneous population can be estimated from knowledge of the time of occurrence for all responses if the response(s) of interest is (are) statistically independent from the other competing responses (risks). In the case

8. Competing Risk Regression Models for Epidemiologic Data
Competing events can preclude the event of interest from occurring in epidemiologic data and can be analyzed by using extensions of survival analysis methods. In this paper, the authors outline 3 regression approaches for estimating 2 key quantities in competing risks analysis: the cause-specific relative hazard (csRH) and the subdistribution relative hazard

9. Bounds for a joint distribution function with fixed sub-distribution functions: Application to competing risks
This paper gives sharp bounds for the joint survival function G(t1, t2,...,tr) ≡ P(X1 > t1, X2 > t2,...,Xr > tr), and for the marginal survival functions Sj(t) ≡ P(Xj > t), j = 1,2,...,r, when the sub-survival functions Sj*(t) ≡ P(Xj > t, Xj = mink=1,2,...,rXk) are fixed. Theorem 1 gives the bounds for r = 2, and Theorem 2 gives the bounds for general

10. Competing risks of mortality with marathons: retrospective analysis
Objective To determine from a societal perspective the risk of sudden cardiac death associated with running in an organised marathon compared with the risk of dying from a motor vehicle crash that might otherwise have taken place if the roads had not been closed.

11. Statistical analysis of the Ames Salmonella/microsome test.
A family of statistical models for analysis of Ames Salmonella/microsome test data is constructed that considers mutation and toxicity as competing risks and allows hyper-Poisson variability. These models have a parameter than can be employed as a mutagenic index because it approximates the slope at zero dose of a dose-response curve adjusted for toxicity. A

12. Modeling the optimum duration of antibiotic prophylaxis in an anthrax outbreak
A critical consideration in effective and measured public health responses to an outbreak of inhalational anthrax is the optimum duration of antibiotic prophylaxis. We develop a competing-risks model to address the duration of antibiotic prophylaxis and the incubation period that accounts for the risks of spore germination and spore clearance. The model
