Antidepressant continuation studies have used 2 different designs. In the placebo substitution design, all patients are initially treated with active medication in an open-label fashion, and then treatment responders are randomized to continue with medication or switch to placebo in a double-blind manner. In the extension design, patients are randomized to a double-blind placebo-controlled acute study at the outset, and responders to active treatment and placebo are continued on the treatment to which they initially responded.

OBJECTIVE: To examine the relative risk and population attributable risk (PAR) of death with dementia of varying type and severity and other risk factors in a population of exceptional longevity. METHODS: Deaths were monitored over 5 years using vital statistics records and newspaper obituaries in 355 individuals with prevalent dementia and 4,328 without in Cache County, UT. Mean age was 83.3 (SD 7.0) years with dementia and 73.7 (SD 6.8) years without. History of coronary artery disease, hypertension, diabetes, and other life-shortening illness was ascertained from interviews.

OBJECTIVE: To test whether cholesterol ester transfer protein (CETP) genotype (VV homozygosity for I405V) is associated with preservation of cognitive function in addition to its association with exceptional longevity. METHODS: We studied Ashkenazi Jews with exceptional longevity (n = 158; age 99.2 +/- 0.3 years) for the associations of CETP VV genotype and lipoprotein phenotype, using the Mini-Mental State Examination (MMSE). To confirm the role of CETP in a younger cohort, we studied subjects from the Einstein Aging Study (EAS) for associations between CETP VV and cognitive impairment.

This consensus statement summarizes key contemporary research themes relevant to understanding the psychology and socioculture of sport injury. Special consideration is given toward high-intensity sport in which elite athlete training and performance efforts are characterized by explosive physical speed and strength, mental fortitude to push physical limits, and maximum effort and commitment to highly challenging goals associated with achieving exceptional performance.

Genetic factors clearly contribute to exceptional longevity and healthy aging in humans, yet the identification of the underlying genes remains a challenge. Longevity is a complex phenotype with modest heritability. Age-related phenotypes with higher heritability may have greater success in gene discovery. Candidate gene and genome-wide association studies (GWAS) for longevity have had only limited success to date.

BACKGROUND: Thromboprophylaxis with rivaroxaban (R) is superior to enoxaparin in patients undergoing major orthopedic surgery (MOS). However, rivaroxaban has never been directly compared with fondaparinux (F), which also shows superior efficacy over enoxaparin. The clinical impact of switching from fondaparinux to rivaroxaban thromboprophylaxis is unclear. OBJECTIVES: To evaluate the efficacy and safety of rivaroxaban or fondaparinux thromboprophylaxis in unselected patients undergoing MOS.

The question of whether temporal equivalence can be established between test species and humans and be useful in the safety assessment of food additives has puzzled risk assessors throughout decades. The basic biological elements in any mammalian species, including humans, such as homeostasis, basal metabolism and body size/surface area, reproduction features, the timing of cellular proliferation, and aging and health as well as the relation between aging and the diet are essential in this discussion.

Food chemical risk management needs, among other things, assessment of exposure. For dietary intake food consumption surveys are the data source to be used. One complicating factor in the usage of these data is the dependence of dietary intake estimates on the time frame of assessment. Central to this time dependence is the within-subject variation regarding the usage of food products and, as a consequence, the intake of chemicals. Within-subject variation is mostly as large as or larger than between-subject variation.

We conducted a 5-year cohort study among 162 self-sufficient residents in a public home for the elderly in Rome, Italy, to evaluate the association between the consumption of specific food groups and nutrients and overall 5-year survival. We used a validated, semiquantitative food-frequency questionnaire to assess diet at baseline.
