objectives : schizophrenia patients often experience relapses once and even more with no limit on number of relapses. the time among relapses are rarely considered in studies. the aim of this study was to identify some risk factors of time to elapses in schizophrenic patients with recurrent events model in survival analysis. methods : in a retrospective longitudinal study, the medical records o...

Abstract. We present a Bayesian analysis for recurrent events data using a nonhomogeneous mixed Poisson point process with a dynamic subject-specific frailty function and a dynamic baseline intensity func- tion. The dynamic subject-specific frailty employs a dynamic piecewise constant function with a known pre-specified grid and the baseline in- tensity uses an unknown grid for the piecewise ...

Abstract A pharmacokinetic–pharmacodynamic (PK-PD) approach is developed for modelling the recurrent bleeding events in patients with severe haemophilia to investigate relationship between factor VIII plasma activity level and instantaneous risk of a bleed. The model incorporates patient-level pharmacokinetic (PK) information obtained through measurements taken prior study which are used fit no...

Congenital factor X deficiency is a rare autosomal recessive bleeding disorder that presents with variable bleeding tendency and prolonged coagulation tests, prothrombin time, and partial thromboplastin time. Thromboembolic events have not been reported in patients with factor X deficiency yet. Herein, we report a patient with factor X deficiency who had recurrent venous thromboembolic events.

background: the study was developed in order to find a subset of potential factors, which affect birth distance pattern, regarding consideration on correlation of events of birth in a family and correlation within clusters/centers which other studies omit these correlations. methods: referring to documents that were registered for family in the health care centers on socio-economical zone, we c...
