Although many investigations examined the relationship between body mass index (BMI) and mortality, little is known about the possible associations between BMI and disease-specific mortality in very elderly people. Here we evaluated this association in an 80-year-old population. In 1998, 675 residents in Japan's Fukuoka Prefecture participated. They were(More)
8-Hydroxy-guanine (8-OH-G) mismatches readily with adenine residues, leading to a G : C to T : A transversion mutation. The human mutY homologue (MUTYH) excises adenine misincorporated opposite 8-OH-G during replication and suppresses mutations caused by reactive oxygen species. We defined the expression of 8-hydroxydeoxyguanosine (8-OHdG) and MUTYH in(More)
PURPOSE This study was designed to compare the diagnostic yield of white light colonoscopy, chromoendoscopy, narrow-band imaging, and autofluorescence imaging in the detection of diminutive lesions. METHODS Thirteen patients with adenomatous polyposis were examined by total colonoscopy using an instrument that incorporated both narrow-band and(More)
Although poor physical fitness is known to be associated with increased mortality in adult and elderly populations, this association is not conclusive in very elderly. The purpose of the present study was to evaluate the association for a very old community-dwelling population. The participants (90 males, 117 females) were 85-year-old individuals residing(More)
The relationship between mortality and impaired cognitive function has not been thoroughly investigated in a very elderly community-dwelling population, and little is known about the association of disease-specific mortality with Mini-Mental State Examination (MMSE) subscale scores. Here we evaluated these data in Japanese community-dwelling elderly. In(More)
Little is known about the association between total cholesterol (TC) and all-cause mortality in the elderly (especially the very elderly). Here we examined the association between TC and all-cause mortality in 207 very elderly (85-year-old) participants. In 2003, we performed a baseline laboratory blood examination, and blood pressure (BP) and body mass(More)
BACKGROUND Little is known about the relationship between disease-specific mortality and high-level activities of daily living in the elderly. We examined whether mortality is associated with high-level activities of daily living in an octogenarian population. METHODS We conducted a population-based cross-sectional and prospective cohort study in 693(More)
