The Prognostic Value of Different Molecular Subtypes of Breast Cancer in Relation to Enhancer-of-Zeste Homologue 2 Expression [PDF]

Journal of Clinical and Diagnostic Research, 2019
Introduction: The role of Enhancer-of-zeste homologue 2 (EZH2) in breast cancer invasion and progression may be attributed to EZH2-mediated epigenetic repression of tumour cells.

Nonparametric analysis of the time structure of seismicity in a geographic region

Annals of Geophysics, 2002
As an alternative to traditional parametric approaches, we suggest nonparametric methods for analyzing temporal data on earthquake occurrences. In particular, the kernel method for estimating the hazard function and the intensity function are presented ...

A Two-Stage Estimation Approach to Cox Regression Under the Five-Parameter Spline Model

Mathematics
The Cox proportional hazards model is one of the most popular regression models for censored survival data. In the Cox model, the baseline hazard function is often modeled by cubic spline functions.

AVERAGE DERIVATIVES FOR HAZARD FUNCTIONS

Econometric Theory, 2004
Summary: This paper develops semiparametric kernel-based estimators of risk-specific hazard functions for competing risks data. Both discrete and continuous failure times are considered. The maintained assumption is that the hazard function depends on explanatory variables only through an index.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Use of Hazard Functions for Determining Power-Law Behaviour in Data

Analytics
Determining the ‘best-fitting’ distribution for data is an important problem in data analysis. Specifically, observing how the distribution of data changes as values below (or above) a threshold are omitted from analyses can be of use in various ...

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

Non-constant hazard function and inflation dynamics [PDF]

, 2009
This paper explores implications of nominal rigidity characterized by a non-constant hazard function for aggregate dynamics. I derive the NKPC under an arbitrary hazard function and parameterize it with the Weibull duration model.

Venous Thromboembolism in Pediatric Bone Sarcoma Patients: A 10‐Year, Single‐Institution Experience Encompassing the COVID‐19 Pandemic

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing

Hazard functions to describe patterns of new and recurrent sick leave episodes for different diagnoses

Scandinavian Journal of Work, Environment & Health, 2012
OBJECTIVES: This study aims to identify the hazard functions that describe the occurrence patterns of new and recurrent sick leave (SL) episodes for mental, respiratory, and musculoskeletal diagnoses.
