Chronic schizophrenic patients have been reported as having higher osteoporosis prevalence. Survey the bone mass among schizophrenic patients and compare with that of the local community population and reported data of the same country to figure out the distribution of bone mass among schizophrenic patients.

Purpose. To assess the prevalence and associated risk factors of age-related macular degeneration (AMD) in an elderly Chinese population in Taiwan. methods. The Shihpai Eye Study was a survey of vision and ocular disease in an elderly Chinese population 65 years of age or older residing in Shihpai, Taipei, Taiwan. Of 2045 elderly residents randomly sampled from the household registration databank, 1361 (66.6%) underwent a detailed ophthalmic examination that included fundus color slides by fundus camera after pupil dilatation. Photographs were graded according to the Wisconsin Age-Related Maculopathy Grading System. results. Fundus photographs were available for 1105 (54.0% in the eligible, 81.2% in the ocular examined) participants. The 47 (4.3%) participants who had ungradable fundus images were older and had more lens opacity. Of the 1058 gradable photographs, the prevalence of early AMD was 9.2% (95% confidence interval [CI], 7.8–10.8); of late AMD, 1.9% (95% CI, 1.3–2.7); of soft drusen, 42.2% (95% CI, 39.7–44.8); of soft indistinct drusen, 4.1% (95% CI, 3.1–5.2); and of any pigmentary change, 8.6% (95% CI, 7.2–10.2). Age was the most significant factor associated with both early and late AMD. The prevalence of early AMD rose from 5.0% in the 65- to 69-year age group to 24.4% in those 80 years of age and older; and for late AMD, from 1.0% to 9.0%. Those who currently drank alcohol had a lower rate of early AMD than did the nondrinker (adjusted odd ratio 0.32, 95% CI: 0.11–0.93, P = 0.037). conclusions. AMD is a common eye disease in the elderly Chinese people in Taiwan. The adjusted prevalence rate of exudative AMD is comparable to that in the Chinese people in the Multiethnic Study of Atherosclerosis (MESA) in the United States but is higher than in the Chinese people in the Beijing study in China. Further studies are needed to clarify the incidence and associated risk factors.

Fall episodes are not unusual among community residents, especially the elderly, and lower muscle strength is an important issue to address in order to prevent falls. A community health survey was conducted in a suburban area of Taiwan, and 1067 older adults were selected for enrollment in the present study. All the enrolled subjects had been visited at their homes; the subjects’ strength of both hands and muscle mass of both legs were measured and well-established questionnaires were finished by certificated paramedic staffs. The incidence of fall episodes in the previous 1 year in the Yilan elderly population was 15.1%, and the female predominance was significant. A significantly higher prevalence of cataracts was found in group who experienced a fall in the past year (64% vs. 54.9% in the non-fall group). Mild or more severe dementia was much more prevalent in the group who experienced a recent fall (33.8% vs. 25.7% in the non-fall group). The strength of both hands tested as the physical function was 17.6 ± 8.0 kg in the recent fall group, significantly weaker than that in the non-fall group (20.7 ± 8.7 kg). Multivariate regression analysis revealed a greater weekly exercise duration and greater strength of both hands reduced the occurrence of falls among the whole and the female population. The standardized effect sizes of hand grip strength between both groups, not trivial, were 0.29 and 0.37 for the total population and the female subpopulation respectively. Less weekly exercise duration and weaker muscle strength were f ound to be independent risk factors of fall episode(s) in an elderly Taiwanese population, especially in the female sub-population. Muscle strength, measured by average of both hands grip strength, was the most significantly factor of one-year fall episode(s) accessed retrospectively.

Objective: Economic evaluation has become increasingly important in healthcare and infection control. This study evaluated the impact of nosocomial infections on cost of illness and length of stay (LOS) in intensive care units (ICUs).Design: A retrospective cohort study.Setting: Medical, surgical, and mixed medical and surgical ICUs in a tertiary-care referral medical center.Patients: Patients admitted to adult ICUs between October 2001 and June 2002 were eligible for the study.Methods: Estimates of the cost and LOS for patients who acquired a nosocomial infection were computed using a stratified analysis and regression approach.Results: During the study period, 778 patients were admitted to the ICUs. Total costs for patients with and without nosocomial infections (median cost, $10,354 and $3,985, respectively) were significantly different (P < .05). The costs stratified by infection site (median differences from $4,687 to $7,365) and primary diagnosis (median differences from $5,585 to $16,507) were also significantly different (P < .05) except for surgical-site infection. After covariates were adjusted for in the multiple linear regression, nosocomial infection increased the total costs by $3,306 per patient and increased the LOS by 18.2 days per patient (P < .001). Each additional day spent in the ICU increased the cost per patient by $353 (P < .001).Conclusions: Nosocomial infections are associated with increased cost of illness and LOS. Prevention of nosocomial infections should reduce direct costs and decrease the LOS.

Objectives: Elderly persons with a physiologic hearing deficit (hearing impairment) are not necessarily socially or emotionally disturbed by the deficit in everyday life (hearing handicap). The self-perception of a hearing handicap in elderly people is a key element in seeking consultation for a hearing impairment or using hearing aids. Thus, it is important to determine the factors associated with the self-perception of a hearing handicap. The aims of the present study were to report the relation between a hearing impairment and the self-perception of a hearing handicap, and the factors associated with a self-perceived hearing handicap among a group of randomly recruited, community-dwelling elderly persons, aged 65 yr and older, in Taipei, Taiwan. Design: A cross-sectional survey of community-dwelling elderly persons aged 65 yr and older (N = 1220) participating in an annual general purpose geriatric health examination in 2005 in Taipei. Pure-tone audiometry and a questionnaire including the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S) were administered, after obtaining the subject's consent to participate in the study. Demographic information, lifestyle, self-report health status, and biochemical data were also collected. Results: There was a moderate association (γ_s = 0.52) between hearing impairment and self-perceived handicap. Only 21.4% of the study subjects with moderate to profound hearing impairment (M4 ≥41 dB HL, N = 555) perceived themselves as hearing-handicapped (HHIE-S total score ≥10). Besides hearing level, marital status (widowed) and self-perceived general health (bad or neutral) were factors that are significantly associated with a self-perceived hearing handicap among elderly subjects with moderate to profound hearing impairment. For study subjects with moderate to profound hearing impairment (M4 ≥41 dB HL), 5.0% of those with HHIE-S <10 and 45.4% of those with HHIE-S ≥10 used or felt that they required hearing aids (χ² test, p < 0.001). These data suggested that a self-perceived hearing handicap (HHIE-S ≥10) is an important indicator for referral of elderly persons for hearing-aid fitting. Conclusions: Our study findings, consistent with those of previous studies, demonstrated that not all elderly persons with impaired hearing function (hearing impairment) perceived a hearing deficit socially or emotionally in everyday life (hearing handicap). Marital status (widowed) and bad/neutral general health were nonaudiologically associated factors with a hearing handicap in the present study. Further, those with a self-perceived hearing handicap reported a higher rate of the use of, or requirement for, hearing aids. Because hearing deterioration is a common biologic process of aging, the results of this study can be used to identify the groups among elderly people with a greater need for hearing screening and hearing rehabilitation services.
