Background
Non-obese individuals could have metabolic disorders that are typically associated with elevated body mass index (BMI), placing them at elevated risk for chronic diseases. This study aimed to describe the prevalence and distribution of metabolically obese, non-obese (MONO) individuals in Malaysia.Methods
We conducted a cross-sectional study involving teachers recruited via multi-stage sampling from the state of Melaka, Malaysia. MONO was defined as individuals with BMI 18.5–29.9 kg/m2 and metabolic syndrome. Metabolic syndrome was diagnosed based on the Harmonization criteria. Participants completed self-reported questionnaires that assessed alcohol intake, sleep duration, smoking, physical activity, and fruit and vegetable consumption.Results
A total of 1168 teachers were included in the analysis. The prevalence of MONO was 17.7% (95% confidence interval [CI], 15.3–20.4). Prevalence of metabolic syndrome among the normal weight and overweight participants was 8.3% (95% CI, 5.8–11.8) and 29.9% (95% CI, 26.3–33.7), respectively. MONO prevalence was higher among males, Indians, and older participants and inversely associated with sleep duration. Metabolic syndrome was also more prevalent among those with central obesity, regardless of whether they were normal or overweight. The odds of metabolic syndrome increased exponentially from 1.9 (for those with BMI 23.0–24.9 kg/m2) to 11.5 (for those with BMI 27.5–29.9 kg/m2) compared to those with BMI 18.5–22.9 kg/m2 after adjustment for confounders.Conclusions
The prevalence of MONO was high, and participants with BMI ≥23.0 kg/m2 had significantly higher odds of metabolic syndrome. Healthcare professionals and physicians should start to screen non-obese individuals for metabolic risk factors to facilitate early targeted intervention. 相似文献2.

Objectives
Sufficient protein intake can decrease undernutrition risk among community-dwelling older adults. This study aimed to increase community-dwelling older adults' daily protein intake with acceptable and applicable protein-enriched bread and readymade meals at home.Design
Double-blind randomized controlled trial of 2 weeks.Setting
Senior residential center in the Netherlands.Participants
Forty-two community-dwelling elderly residents (≥65 years) participated, with a mean age of 74.0 ± 6.9 years and mean body mass index of 28.5 ± 3.45 kg/m2.Intervention
The intervention group (n = 22) received 5 protein-enriched readymade meals and plentiful protein-enriched bread during 2 weeks, whereas the control group (n = 20) received the regular equivalents during these 2 weeks.Measurements
Food intake was assessed by using dietary food record-assisted 24-hour recalls and by weighing meal leftovers. Acceptability of the enriched products was assessed with product evaluation questionnaires and in-depth interviews.Results
Mean intake of food products (g) and energy (kJ) did not differ significantly between the control and the intervention groups. Total daily protein intake in the intervention group was 14.6 g higher than in the control group (87.7 vs 73.1 g/d, P = .004). Expressed in g/kg body weight per day, protein intake was significantly higher in the intervention group than in the control group (1.25 vs 0.99 g/kg/d, P = .003). The enriched products were equally liked, scoring 7.7 of 10.0. The in-depth interviews with participants indicated high acceptability of the enriched products.Conclusion
This study showed that community-dwelling older adults' protein intake can be increased to recommended levels with highly acceptable and applicable protein-enriched products that fit into the normal eating pattern. Future studies should investigate whether this effect is maintained in the long-term among a frailer population. 相似文献3.

Background
Depression increases disability and health care utilization in older patients with chronic obstructive pulmonary disease (COPD).Objectives
To determine contribution of depressive symptoms to the incidence of moderate-severe and severe acute exacerbations of COPD (AECOPD) over 3 years.Design
We analyzed data collected from a prospective cohort of patients with COPD (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints; ECLIPSE).Setting
Multicentered outpatient.Participants
A total of 2059 patients with COPD with complete data (63.7% men, mean age 63.4 + 7.1 years).Measurements
Depression was assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Moderate-severe AECOPDs were collected; a subset of very severe AECOPD was defined as requiring hospital admission.Results
A total of 540 (26%) patients with COPD reported high depressive symptoms (CES-D ≥16). High depressive symptoms at baseline related to an increased risk of moderate-severe and severe AECOPD during the follow-up (odds ratio [OR] 1.18; 95% confidence interval [CI] 1.07–1.30; for moderate-severe and OR 1.36; 95% CI 1.09–1.69 for severe events risk of hospitalizations) independent of key covariates of an AECOPD history before recruitment in the study, history of gastroesophageal reflux, baseline severity of airflow limitation, and white blood cell count that were also associated with an increased risk of moderate to severe exacerbations (all P < .001).Conclusion
Presence of high depressive symptoms at baseline were associated with subsequent moderate-severe exacerbations and hospital admissions in patients with COPD over 3 years, independent of a history of exacerbations and other demographic and clinical factors. Targeted personalized medicine that focuses both on AECOPD risk and depression may be a step forward to improving prognosis of patients with COPD. 相似文献4.

Objective
To analyze the association between dietary patterns and the 12-year risk of frailty and its components in community-dwelling elderly French adults.Design
A prospective cohort study.Setting
The Bordeaux sample of the Three-City Study.Participants
A total of 972 initially nonfrail nondemented participants (336 men and 636 women) aged 73 years on average, re-examined at least once over 12 years.Measurements
Five sex-specific dietary clusters were previously derived at baseline. Frailty incident to the baseline visit was defined as having at least three out of the following 5 criteria: unintentional weight loss, exhaustion, low energy expenditure, slowness, and muscle weakness. Multivariate Cox proportional hazard models were used to assess the association between dietary clusters and the risk of frailty and its components.Results
In total, 78 men for 3719 person-years and 221 women for 7027 person-years became frail over the follow-up. In multivariate analyses, men in the “pasta” pattern and women in the “biscuits and snacking” pattern had a significantly higher risk of frailty compared with those in the “healthy” pattern [hazard ratio (HR) 2.2; 95% confidence interval (CI) 1.1–4.4 and HR 1.8; 95% CI 1.2–2.8, respectively; P = .09 and P = .13 for the global test of significance of risk difference across clusters, respectively]. In men, “biscuits and snacking” and “pasta” patterns were significantly associated with higher risk for muscle weakness (HR 3.3; 95% CI 1.6–7.0 and HR 2.1; 95% CI 1.2–3.7, respectively; P = .003 for global test).Conclusions
This 12-year prospective population-based study suggests that some particular unhealthy dietary patterns may increase the risk of frailty in older adults. 相似文献5.

Objectives
A natural decline of muscle strength occurs during the aging process; however, preserving muscle strength may lower the rate of many preventable diseases such as diabetes, especially in higher risk populations. The purpose of this study was to examine the sex-specific association between muscle weakness and incident diabetes in older Mexican Americans.Design
Observational, longitudinal study.Setting
Urban and rural households in the Southwestern United States.Participants
A subsample of 1903 Mexican Americans aged at least 65 years without diabetes at baseline were followed for 19 years.Measurements
Muscle weakness was assessed with a hand-held dynamometer and was normalized to body weight (normalized grip strength). Male and female participants were categorized as weak if their normalized grip strength was ≤0.46 and ≤0.30, respectively. Sex-stratified Cox proportional hazard regression models were used to determine the association between muscle weakness and incident diabetes (self-reported) when using age as an entry variable and after adjusting for education, employment status, instrumental activities of daily living disability, interview language, marital status, and obesity. A sensitivity analysis was performed to account for influential outliers for the outcome variable (incident diabetes) and the model was re-run.Results
The hazard ratio for incident diabetes was 1.05 (95% confidence interval: 1.02–1.09; P < .001) in weak vs not-weak male participants and 1.38 (95% confidence interval: 1.35–1.41; P < .001) in weak vs not-weak female participants, after adjusting for relevant covariates.Conclusions
Muscle weakness was associated with an increased rate of diabetes in older male and female Mexican Americans. Health professionals should encourage activities that preserve muscle strength, thereby preventing the incidence of diabetes in older Mexican Americans. 相似文献7.

Background
Many adults are discharged to skilled nursing facilities (SNFs) prior to returning home from the hospital. Patient characteristics and factors that can help to prevent postdischarge adverse outcomes are poorly understood.Objective
To identify whether early post–SNF discharge care reduces likelihood of 30-day hospital readmissions.Design
Secondary data analysis using the Electronic Medical Record, Medicare, Medicaid and the Minimum Data Set.Participants/setting
Older (age > 65 years), community-dwelling adults admitted to a safety net hospital in the Midwest for 3 or more nights and discharged home after an SNF stay (n = 1543).Measurements
The primary outcome was hospital readmission within 30 days of SNF discharge. The primary independent variables were either a home health visit or an outpatient provider visit within a week of SNF discharge.Results
Out of 8754 community-dwelling, hospitalized older adults, 3025 (34.6%) were discharged to an SNF, of whom 1543 (51.0%) returned home. Among the SNF to home group, a home health visit within a week of SNF discharge was associated with reduced hazard of 30-day hospital readmission [adjusted hazard ratio (aHR) 0.61, P < .001] but outpatient provider visits were not associated with reduced risk of hospital readmission (aHR = 0.67, P = .821).Conclusion
For patients discharged from an SNF to home, the finding that a home health visit within a week of discharge is associated with reduced hazard of 30-day hospital readmissions suggests a potential avenue for intervention. 相似文献8.

Objectives
To investigate the association between benzodiazepine and related drug (BZDR) use and hip fracture as well as postfracture mortality and duration of hospital stay in community-dwellers with and without Alzheimer disease (AD).Design
Retrospective cohort study.Setting
The register-based Medication Use and Alzheimer's disease (MEDALZ) study, including all community-dwelling persons diagnosed with AD in Finland during 2005–2011 (n = 70,718) and their matched comparison persons without AD.Participants
Persons without BZDR use during the year preceding the AD diagnosis or the corresponding matching date as well as persons without history of hip fracture were included in this study.Measurements
We investigated the risk of hip fracture associated with BZDR use compared with nonuse separately in persons with and without AD. Further, we investigated the association between BZDR use during hip fracture and 1-year mortality as well as longer than a 4-month hospital stay after hip fracture. Associations were reported as hazard ratios and odds ratios with 95% confidence intervals (CI).Results
BZDR use was associated with an increased risk of hip fracture in persons with and without AD (adjusted hazard ratio 1.4 [95% CI 1.2–1.7] and 1.6 [95% CI 1.3–1.9], respectively). BZDR use during hip fracture was associated with longer than 4-month postfracture hospital stay in persons with AD [adjusted odds ratio 1.9 (95% CI 1.3–2.8)] but not in comparison persons. One-year mortality was not associated with BZDR use during hip fracture.Conclusions
Higher threshold in prescribing BZDRs for neuropsychiatric symptoms might decrease the hip fracture rate and affect the length of hospital stay in persons with AD. 相似文献9.

Objective
To determine whether the implementation of a national program to improve quality of care in geriatric rehabilitation (GR) in the Netherlands improves successful GR in terms of independence in activities of daily living (ADL), discharge destination, and length of stay.Design
Prospective longitudinal study, comparing 2 consecutive cohorts: at the start of implementation (n = 386) and at 1 year after implementation (n = 357) of this program.Setting/Participants
Included were 16 skilled nursing facilities, 743 patients (median age 80 years, interquartile range 72–85; 64.5% females) indicated for GR and their health care professionals (elderly care physicians, physiotherapists, and nursing staff).Intervention
National program to stimulate self-organizing capacity to develop integrated care to improve GR service delivery in 4 domains: alignment with patients’ (care) needs, care coordination, team cooperation, and quality of care.Measurements
Data on patients’ characteristics, functional outcomes at admission and discharge, length of stay, and discharge destination were collected via an online questionnaire sent to health care professionals. The primary outcome measure was successful rehabilitation defined as independence in ADL (Barthel Index ≥15), discharge home, and a short length of stay (lowest 25% per diagnostic group). Generalized estimating equation analysis was used to adjust for age, gender, and clustering effects in the total population and for the 2 largest diagnostic subgroups, traumatic injuries and stroke.Results
In the total population, at 1 year postimplementation there was 12% more ADL independence [odds ratio (OR) 1.59, 95% confidence interval (CI) 1.00–2.54]. Although successful rehabilitation (independence in ADL, discharge home, short length of stay) was similar in the 2 cohorts, patients with traumatic injuries were more successful 1 year postimplementation (OR 1.61, 95% CI 1.01–2.54). In stroke patients, successful rehabilitation was similar between the cohorts, but with more independence in ADL in the follow-up cohort (OR 1.99, 95% CI 1.09–3.63).Conclusions
This study shows that 1-year after the implementation of the Dutch national program to improve quality of care there was more independence in ADL at discharge, but the combined outcome of successful GR (independence in ADL, discharge home, short length of stay) was only significantly improved in patients with traumatic injuries. 相似文献10.

Objective
To evaluate the benefits of the national stroke postacute care (PAC) program on clinical outcomes and subsequent healthcare utilization.Design
Propensity score-matched case-control study using the National Health Insurance data.Participants
A total of 1480 stroke cases receiving PAC services and 3159 matched controls with similar stroke severity but without PAC services.Measurements
Demographic characteristics, functional outcomes (modified Rankin Scale, Barthel Index, Lawton-Brody Instrumental Activities of Daily Living, Functional Oral Intake Scale, Mini-Nutritional Assessment, Berg Balance Test, Usual Gait Speed Test, 6-Minute Walk Test, Fugl-Meyer Assessment (modified sensation and motor), Mini-Mental State Examination, Motor Activity Log, and the Concise Chinese Aphasia Test), subsequent healthcare utilization (90-day stroke re-admission and emergency department visits), and 90-day mortality.Results
After propensity score matching, baseline characteristics, stroke severity, and status of healthcare utilization before index stroke admission were similar between cases and controls. After PAC services, the case group obtained significant improvement in all functional domains and may have reduced subsequent disability. Among all functional assessments, balance was the most significantly improved domain and was suggestive for the reduction of subsequent falls risk and related injuries. Compared with controls, patients receiving PAC services had significantly lower 90-day hospital re-admissions [11.1% vs 21.0%, adjusted odds ratio (aOR) 0.47 with 95% confidence interval (CI) 0.34–0.64], stroke-related re-admissions (2.1% vs 8.8%, aOR 0.22, 95% CI 0.12–0.41), and emergency department visits (13.5% vs 24.0%, aOR 0.49, 95% CI 0.37–0.65), but the 90-day mortality rate remained similar between groups (1.4% case group vs 2.0% control group, aOR 0.68, 95% CI 0.29–1.62).Conclusions
PAC significantly improved the recovery of stroke patients in all functional domains through the program, with universal interorganizational staff training, periodic functional assessment, and high-intensity rehabilitation. Further longitudinal research is needed to evaluate the long-term survival benefits and healthcare utilization. 相似文献11.

Background
Diabetes mellitus is a strong risk factor for cardiovascular disease. However, the age-specific association of diabetes with cardiovascular risk, especially in the elderly, remains unclear in non-Western populations.Methods
A pooled analysis was conducted using 8 cohort studies (mean follow-up period, 10.3 years) in Japan, combining the data from 38,854 individual participants without history of cardiovascular disease. In all, 1867 of the participants had diabetes, defined based on the 1998 World Health Organization criteria. The association between diabetes and the risk of death from cardiovascular disease, coronary heart disease (CHD), and stroke was estimated using a stratified Cox model, accounting for variability of baseline hazard functions among cohorts.Results
During the follow-up, 1376 subjects died of cardiovascular disease (including 268 of coronary heart disease and 621 of stroke). Diabetes was associated with an increased risk of cardiovascular death after multivariable adjustment (hazard ratio [HR] 1.62; 95% confidence interval [CI], 1.35–1.94). Similarly, diabetes was a risk factor for CHD (HR 2.13; 95% CI, 1.47–3.09) and stroke (HR 1.40; 95% CI, 1.05–1.85). In the age-stratified analysis of the risk of cardiovascular death, the relative effects of diabetes were consistent across age groups (p for heterogeneity = 0.18), whereas the excess absolute risks of diabetes were greater in participants in their 70s and 80s than in younger subjects.Conclusions
The management of diabetes is important to reduce the risk of death from cardiovascular disease, not only in midlife but also in late life, in the Japanese population. 相似文献12.

Objectives
Use of exercise technologies has benefits for community-dwelling older adults in terms of improved gait and balance. But research on the feasibility of use of exercise technologies in various geriatric health care settings is lacking. Hence, the current study examined the feasibility of implementing an exercise technology intended to augment rehabilitation in patients receiving post-acute care (PAC) in a skilled nursing facility (SNF). We focused on 3 indicators of feasibility: extent of usage (including predictors of more intense use), patients' acceptability of the technology, and limited efficacy.Design
Cross-sectional study with data from patients' electronic medical records (EMR), exercise technology portal, and patient interviews.Setting
SNF.Participants
A sample of post-acute patients (n = 237).Measurements
Sociodemographic and health-related variables, time spent using the technology, and 8 items of the Physical Activity Enjoyment Scale (PACES).Results
Average time spent using the technology varied greatly (range, 1–460 minutes). A regression analysis showed that patients who had a longer length of stay (β = .01, P < .05) and were younger (β = ?0.01, P < .05) spent significantly more time using the technology. Acceptability of technology was high among patients. Finally, patients who used the technology had lower 30-day rehospitalization rates.Conclusion
Exercise technology is feasible to use in supporting rehabilitation in patients receiving PAC in a SNF and seems to have beneficial effects. 相似文献13.

Objectives
To investigate the prevalence and factors associated with the use of medications of questionable benefit throughout the final year of life of older adults who died with dementia.Design
Register-based, longitudinal cohort study.Setting
Entire Sweden.Participants
All older adults (≥75 years) who died with dementia between 2007 and 2013 (n = 120,067).Measurements
Exposure to medications of questionable benefit was calculated for each of the last 12 months before death, based on longitudinal data from the Swedish Prescribed Drug Register.Results
The proportion of older adults with dementia who received at least 1 medication of questionable benefit decreased from 38.6% 12 months before death to 34.7% during the final month before death (P < .001 for trend). Among older adults with dementia who used at least 1 medication of questionable benefit 12 months before death, 74.8% remained exposed until their last month of life. Living in an institution was independently associated with a 15% reduction of the likelihood to receive ≥1 medication of questionable benefit during the last month before death (odds ratio 0.85, 95% confidence interval 0.88–0.83). Antidementia drugs accounted for one-fifth of the total number of medications of questionable benefit. Lipid-lowering agents were used by 8.3% of individuals during their final month of life (10.2% of community-dwellers and 6.6% of institutionalized people, P < .001).Conclusion
Clinicians caring for older adults with advanced dementia should be provided with reliable tools to help them reduce the burden of medications of questionable benefit near the end of life. 相似文献14.

Background
It is well established that low muscle mass affects physical performance in chronic obstructive pulmonary disease (COPD). We hypothesize that combined low muscle mass and abdominal obesity may also adversely influence the cardiometabolic risk profile in COPD, even in those with normal weight. The cardiometabolic risk profile and the responsiveness to 4 months high-intensity exercise training was assessed in normal-weight patients with COPD with low muscle mass stratified by abdominal obesity.Methods
This is a cross-sectional study including 81 clinically stable patients with COPD (age 62.5 ± 8.2 years; 50.6% males; forced expiratory volume in 1 second 55.1 ± 19.5 percentage predicted) with fat-free mass index <25th percentile eligible for outpatient pulmonary rehabilitation. Body composition, blood biomarkers, blood pressure, physical activity level, dietary intake, and physical performance were assessed at baseline and in a subgroup after 4 months of exercise training.Results
Mean body mass index was 22.7 ± 2.7 kg/m2, and 75% of patients had abdominal obesity. Abdominally obese patients had higher glucose, insulin, homeostatic model assessment for insulin resistance (HOMA-IR), branched chain amino acids and a higher prevalence of metabolic syndrome compared with those without abdominal obesity. Exercise training improved cycling endurance time and quadriceps strength, but did not yield a clinically meaningful improvement of the cardiometabolic risk profile. Triglycerides showed a significant decrease, while the HOMA-IR increased.Conclusion
Abdominal obesity is highly prevalent in normal-weight patients with COPD with low muscle mass who showed an increased cardiometabolic risk compared with patients without abdominal obesity. This cardiometabolic risk profile was not altered after 4 months of exercise training. 相似文献15.

Objectives
Initial gait speed is a good predictor of dementia in later life. This prospective study used repeated measures analysis to identify potential gait performance trajectory patterns and to determine whether gait performance trajectory patterns were associated with incident disabling dementia among community-dwelling older Japanese.Design
A prospective, observational, population-based follow-up study.Setting
Japan, 2002 to 2014.Participants
A total of 1686 adults without dementia (mean [SD] age, 71.2 [5.6] years; women, 56.3%) aged 65 to 90 years participated in annual geriatric health assessments during the period from June 2002 through July 2014. The average number of follow-up assessments was 3.9, and the total number of observations was 6509.Measurements
Gait performance was assessed by measuring gait speed and step length at usual and maximum paces. A review of municipal databases in the Japanese public long-term care insurance system revealed that 196 (11.6%) participants developed disabling dementia through December 2014.Results
We identified 3 distinct trajectory patterns (high, middle, and low) in gait speed and step length at usual and maximum paces in adults aged 65 to 90 years; these trajectory patterns showed parallel declines among men and women. After adjusting for important confounders, participants in the low trajectory groups for gait speed and step length at usual pace were 3.46 (95% confidence interval 1.88–6.40) and 2.12 (1.29–3.49) times as likely to develop incident disabling dementia, respectively, as those in the high trajectory group. The respective values for low trajectories of gait speed and step length at maximum pace were 2.05 (1.02–4.14) and 2.80 (1.48–5.28), respectively.Conclusions
Regardless of baseline level, the 3 major trajectory patterns for gait speed and step length tended to show similar age-related changes in men and women in later life. Individuals with low trajectories for gait speed and step length had a higher dementia risk, which highlights the importance of interventions for improvements in gait performance, even among older adults with low gait performance. 相似文献16.

Background
This study was conducted to evaluate the association between hemorrhoid and risk of incident peripheral artery occlusive disease (PAOD).Methods
Using the Taiwanese Longitudinal Health Insurance Database 2000, we compared the incident PAOD risk between the hemorrhoid and the non-hemorrhoid cohorts. Both of these cohorts were followed up from the index date until the date of PAOD diagnosis, withdrawal from the National Health Insurance program, or the end of 2011.Results
The mean follow-up period was 6.82 (standard deviation [SD], 3.22) and 6.70 (SD, 3.23) years in the hemorrhoid and non-hemorrhoid cohorts, respectively. The plot of the Kaplan–Meier analysis showed that, by the end of the 12-year follow-up period, the cumulative incidence of PAOD was significantly higher for the hemorrhoid cohort than for the non-hemorrhoid cohort (log-rank test: P < 0.001).Conclusions
A significantly increased PAOD risk in patients with hemorrhoids was found in this nationwide cohort study. 相似文献17.

Objectives
Persons with osteoporotic fracture history are subject to an increased risk for subsequent fractures and mortality. The aim of this retrospective study was to investigate the impact of a previous osteoporotic low-impact (fragility) index fracture (eg, forearm, lower leg) on mortality of a subsequent femoral fracture.Design
Retrospective cohort study.Participants/measurements
Claims data of a German health insurance agency including >1.2 million insurants aged 65 years or older and observed between 2004 and 2009.Methods
A multistate model was developed handling index fractures and care need as time-dependent exposures, while age was chosen as the underlying time scale. Excess risks were expressed as differences in cause-specific hazards. Nelson-Aalen estimates were used for their nonparametric estimation. Time-simultaneous statistical inference was based on confidence bands provided by wild bootstrap resampling.Results
Excess femoral fracture risk increased with progressive age and was highest in persons with care need. It was observed starting from an age of 79 years in women and 85 years in men onward. A prior index fracture increased mortality after a femoral fracture by increasing femoral fracture risk, while leaving the hazard of death after a subsequent femoral fracture unchanged.Conclusions
The results indicated that increased mortality of a subsequent femoral fracture is not triggered by an intrinsically increased mortality hazard but an increased femoral fracture incidence. 相似文献18.

Background
Stroke severity is an important outcome predictor for intracerebral hemorrhage (ICH) but is typically unavailable in administrative claims data. We validated a claims-based stroke severity index (SSI) in patients with ICH in Taiwan.Methods
Consecutive ICH patients from hospital-based stroke registries were linked with a nationwide claims database. Stroke severity, assessed using the National Institutes of Health Stroke Scale (NIHSS), and functional outcomes, assessed using the modified Rankin Scale (mRS), were obtained from the registries. The SSI was calculated based on billing codes in each patient's claims. We assessed two types of criterion-related validity (concurrent validity and predictive validity) by correlating the SSI with the NIHSS and the mRS. Logistic regression models with or without stroke severity as a continuous covariate were fitted to predict mortality at 3, 6, and 12 months.Results
The concurrent validity of the SSI was established by its significant correlation with the admission NIHSS (r = 0.731; 95% confidence interval [CI], 0.705–0.755), and the predictive validity was verified by its significant correlations with the 3-month (r = 0.696; 95% CI, 0.665–0.724), 6-month (r = 0.685; 95% CI, 0.653–0.715) and 1-year (r = 0.664; 95% CI, 0.622–0.702) mRS. Mortality models with NIHSS had the highest area under the receiver operating characteristic curve, followed by models with SSI and models without any marker of stroke severity.Conclusions
The SSI appears to be a valid proxy for the NIHSS and an effective adjustment for stroke severity in studies of ICH outcome with administrative claims data. 相似文献19.

Background
Older adults with depression have increased risk of frailty and death.Objective
To determine if history of depression hinders future physical and functional capacity.Design, setting, and participants
Prospective longitudinal cohort study of 1148 men aged 70-87 years who were living in the Perth metropolitan community in 2001-2004 and completed a follow-up assessment of physical and functional capacity in 2011–2012.Main outcome and measures
Outcomes were collected in 2011–2012 and included 4 measures of physical function (timed up-and-go, timed sit-to-stand, functional reach, and step test) and the assessment of basic (activities of daily living) and instrumental activities of daily living. We also collected information on depression and frailty [using the FRAIL (fatigue resistance ambulation illness, and loss of weight) scale] in 2001–2004 and 2011–2012. Frail men at the 2001–2004 were excluded from the analyses.Results
Men with history of depression at the 2001–2004 assessment showed significantly worse performance than their counterparts in the timed sit-to-stand and step tests 9 years later. They also had approximately twice the risk of attaining the lowest decile of performance in both tests (analyses adjusted for age, education, and prevalent depressive symptoms). In addition, the adjusted risk ratio of impaired instrumental activities of daily living was 58% (95% confidence interval 15%, 116%) greater for men with than without history of past depression. These associations were particularly robust for men with current depression at the 2001–2004 assessment.Conclusions
Nonfrail older men with history of current or past depression showed greater impairment of physical and functional capacity 9 years later. Older men with history of depression may benefit from regular monitoring of physical and occupational function and should be targeted by preventive trials designed to improve function and decrease frailty. 相似文献20.
