BACKGROUND One of the most important selection criteria for spinal metastases surgery is life expectancy and the most important system for this prediction has been proposed by Tokuhashi. The aim of this study was to evaluate predictive value of the Tokuhashi score for life expectancy in Iranian patients with spinal metastases one year after diagnosis. METHODS From February 2007 to March 2009,...

OBJECTIVES We examined whether racial disparities in stage-specific colorectal cancer survival changed between 1960 and 2005. METHODS We used US Mortality Multiple-Cause-of-Death Data Files and intercensal estimates to calculate standardized mortality rates by gender and race from 1960 to 2005. We used Surveillance, Epidemiology, and End Results (SEER) data to estimate stage-specific colorect...

Modeling of subjective survival is critical to the use of mortality expectations in economic models and the life insurance industry. Subjective scaling factors that are used to adjust average survival probabilities for individual expectations are often based on a single observation of personal life expectancy and assumed to be constant for any projected target age. Using survey data on subjecti...

The aim of this study was to assess the magnitude of the survival benefit of renal transplantation compared with dialysis in patients selected for transplantation in Scotland. Longitudinal study of survival and mortality risk in all adult patients (1732) listed for a first transplant between January 1, 1989, and December 31, 1989, in Scotland. A time-dependent Cox regression analysis adjusted f...

The life table entropy provides useful information for understanding improvements in mortality and survival in a population. In this paper we take a closer look at the life table entropy and use advanced mathematical methods to provide additional insights for understanding how it relates to changes in mortality and survival. By studying the entropy (H) as a functional, we show that changes in t...

OBJECTIVE To determine the life stages in which disability-free life expectancy is shortened before the age of 70 years. METHOD A retrospective longitudinal analysis was carried out in a cohort of 1,286 non-institutionalized people aged from 70 to 74 years old living in metropolitan areas. Disability was measured by instrumental and basic activities of daily living. Disability-free life expec...

Down syndrome (DS) is one of the most common causes developmental disability in world with a prevalence 1:800 live births. Persons born DS are at increased risk for various health conditions, including thyroid disease, leukemia, congenital heart defects, gastrointestinal tract abnormalities, obesity, and diabetes mellitus. Despite this chronic life expectancy individuals has continued to improv...

OBJECTIVE To determine life expectancy of children with cerebral palsy. DESIGN Cohort analysis, by means of register compiled from multiple sources of ascertainment, of all children with cerebral palsy born during 1966-84 to mothers resident in Mersey region. Status of children was determined by flagging through NHS central register. SUBJECTS 1258 subjects with idiopathic cerebral palsy, of...

OBJECTIVE To study the effect of renal disease on the standardized mortality ratio (SMR) and life expectancy of patients with systemic lupus erythematosus (SLE). METHODS Patients whose diagnosis met ≥4 American College of Rheumatology criteria for SLE were longitudinally followed up from 1995 to 2011. The cumulative survival rate, SMR, and life expectancy were calculated, and the effect of re...
