Objectives
To investigate the prevalence and associated factors of sarcopenia defined by different criteria in nursing home residents.Design
A cross-sectional study.Setting
Four nursing homes in Chengdu, China.Participants
Elderly adults aged 65 years or older.Measurements
We applied 4 diagnostic criteria [European Working Group on Sarcopenia in Older People (EWGSOP), Asia Working Group for Sarcopenia (AWGS), International Working Group on Sarcopenia (IWGS), and Foundation for the National Institutes of Health (FNIH)] to define sarcopenia. Muscle mass, strength, and function were measured based on bioimpedance analysis, handgrip strength, and walking speed, respectively. Nutrition status, activities of daily living, calf circumference (CC), and other covariates were evaluated.Results
We included 277 participants. The prevalence of sarcopenia was 32.5%, 34.3%, 38.3%, and 31.4% according to the EWGSOP, AWGS, IWGS, and FNIH criteria, respectively. Fifty-eight participants (20.9%) were sarcopenic by all the 4 criteria. Regardless of the diagnostic criteria of sarcopenia, malnutrition was independently associated with sarcopenia [EWGSOP: odds ratio (OR) 4.02, 95% confidence interval (CI) 1.05-15.39; IWGS: OR 2.46, 95% CI 1.23-4.90; AWGS: OR 3.29, 95% CI 1.49-7.28; FNIH: OR 4.52, 95% CI 1.28-16.00], whereas CC was negatively associated with sarcopenia [EWGSOP: OR per standard deviation (SD) 0.32, 95% CI 0.20-0.52; IWGS: OR per SD 0.26, 95% CI 0.15-0.43; AWGS: OR per SD 0.32, 95% CI 0.19-0.52; FNIH: OR per SD 0.39, 95% CI 0.25-0.60]. Furthermore, falls ≥1 time in the past year were associated with AWGS-defined sarcopenia (OR 2.92, 95% CI 1.04-8.22).Conclusion/Implications
Sarcopenia is highly prevalent in elderly Chinese nursing home residents regardless of the diagnostic criteria. Malnutrition and CC are associated with sarcopenia defined by different criteria. Therefore, it is important to assess sarcopenia and malnutrition in the management of nursing home residents. Prospective studies addressing the outcomes of sarcopenia in nursing home residents are warranted. 相似文献2.

Objectives
This study aimed to investigate the additive effects of sarcopenia and low serum albumin level on the risk of incident disability in older adults.Design
Prospective cohort study.Setting
A Japanese community.Participants
Community-dwelling older adults aged ≥65 years, without disability at baseline (N = 4452).Measures
Sarcopenia was defined as the presence of both poor muscle function (low physical performance or muscle strength) and low muscle mass. Low serum albumin level was defined as ≤4.0 g/dL. Other potential confounding factors (demographics, medical history, depressive symptoms, and cognitive function) were also assessed. Incident disability was monitored based on Long-Term Care Insurance certification during follow-up.Results
The median follow-up duration was 30 (interquartile range, 28-32) months. Participants were classified into mutually exclusive groups based on sarcopenia status and serum albumin levels: nonsarcopenia/normal serum albumin (n = 3719), low serum albumin alone (n = 552), sarcopenia alone (n = 132), and sarcopenia/low serum albumin (n = 49). A Cox hazards regression showed that the low serum albumin alone [hazard ratios (HR) = 1.71, 95% confidence interval (CI) = 1.26-2.33], sarcopenia alone (HR = 2.74, 95% CI = 1.58-4.77), and sarcopenia/low serum albumin groups (HR = 3.73, 95% CI = 1.87-7.44) had higher risk of disability than the nonsarcopenia/normal serum albumin group after adjusting for the covariates.Conclusions/Implications
Sarcopenia and low serum albumin level synergistically increase the risk of incident disability in older adults. Sarcopenia in older adults at risk of malnutrition should be detected early, and appropriate interventions should be implemented. 相似文献3.

Objective
To examine the screening ability of SARC-F for older adults using a meta-analysis.Design
Meta-analysis.Setting and Participants
The literature review was conducted using MEDLINE, Cochrane Database of Systematic Reviews, and ClinicalTrials.gov. Articles written on and after 1960 that included data regarding the sensitivity and specificity of SARC-F's diagnostic criteria for sarcopenia in older adults were searched.Measures
The bivariate random effects model was used to calculate the summary estimates of sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR). The summary receiver operating characteristic curve was used to summarize the overall test performance.Results
Seven studies involving a total of 12,800 subjects met the eligibility criteria of our study. The pooled results of sensitivity, specificity, PLR, NLR, and DOR with the European Working Group on Sarcopenia in Older People as the reference standard were 0.21 [95% confidence interval (CI), 0.13-0.31], 0.90 (95% CI, 0.83-0.94), 2.16 (95% CI, 1.51-3.09), 0.87 (95% CI, 0.80-0.95), and 2.47 (95% CI, 1.64-3.74), respectively. Overall, we achieved similar pooled results of sensitivity and specificity for studies using the International Working Group on Sarcopenia and Asian Working Group for Sarcopenia as the reference standards. Because few studies used the Foundation National Institute of Health reference standards, a meta-analysis was not performed.Conclusions/Implications
Although the screening sensitivity performance of SARC-F was poor, its specificity was high; thus, it is an effective tool for selecting subjects who should undergo further testing for confirming a diagnosis of sarcopenia. 相似文献4.

Objective
The Mini Sarcopenia Risk Assessment (MSRA), a new sarcopenia screening tool, has 2 versions: MSRA-7 (full version, 7 items) and MSRA-5 (short version, 5 items). We aimed to compare the diagnostic values of MSRA-7 and MSRA-5 to SARC-F for screening sarcopenia.Design
A diagnostic accuracy study.Setting
A community in Chengdu, China.Participants
Older adults.Measurements
Muscle mass, strength, and physical performance were tested using a bioimpedance analysis (BIA) device, handgrip strength, and walking speed, respectively. Using the Asian Working Group for Sarcopenia (AWGS) criteria as the gold standard, the sensitivity/specificity analyses of the 3 scales were assessed. Receiver operating characteristic (ROC) curves and area under the ROC curves (AUC) were used to compare the overall diagnostic accuracy of the 3 scales.Results
We recruited 384 participants. Against the AWGS criteria, SARC-F had a sensitivity of 29.5% and a specificity of 98.1%, and the MSRA-7 had a sensitivity of 86.9% and a specificity of 39.6%, whereas the MSRA-5 had a sensitivity of 90.2% and a specificity of 70.6%. The AUCs of SARC-F, MSRA-7, and MSRA-5 were 0.89 [95% confidence interval (CI), 0.86-0.92], 0.70 (95% CI, 0.65-0.74), and 0.85 (95% CI, 0.81-0.89), respectively. The differences in AUCs between SARC-F and MSRA-7 and in those between MSRA-7 and MSRA-5 were statistically significant (P <.001), but the difference between SARC-F and MSRA-5 was not statistically significant (P = .130).Conclusion
MSRA-5 may serve as a novel screening tool for sarcopenia in Chinese community-dwelling older adults. SARC-F, a class screening tool, is also suitable for this population. MSRA-5 and SARC-F demonstrated a similar diagnostic accuracy in our study population. MSRA-5 has better sensitivity, whereas SARC-F has better specificity. However, the diagnostic value of MSRA needs to be further validated in different populations. 相似文献5.

Objectives
The aim of this study is to demonstrate the ability of the basal metabolic rate (BMR) to detect frailty and sarcopenia in older males.Setting and Participants
A total of 305 male patients undergoing comprehensive geriatric assessment were included in the study.Measures
The frailty status was assessed with the Fried criteria. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People criteria. BMR is calculated by bioimpedance analysis. Areas under the curves (AUCs) of receiver operating characteristic analyses were used to test the predictive accuracy of BMR in detecting sarcopenia.Results
The mean age was 74.52 ± 7.51 years. Among the patients in the sample, 95 (31.1%) had sarcopenia and 55 (18%) had frailty. Patients who had a BMR <1612 kcal/d had a higher frequency of frailty than those who had a BMR ≥1612 kcal/d (67.3 vs 32.7, P < .001). Results were similar for sarcopenia (77.9 vs 22.1, P < .001). When BMR was divided by body surface area (BSA), BMR/BSA with a cut-off of 874 kcal/m2 had a sensitivity of 80% and a specificity of 68%, and the AUC was 0.82 for BMR/BSA, in diagnosing sarcopenia (P < .01). The participants without sarcopenia had a higher BMR/BSA for the unadjusted (OR = 8.00, 95% CI 4.52-14.19, P < .001) and adjusted analyses (OR = 6.60, 95% CI 3.52-12.38, P < .001).Conclusions
Older male patients with sarcopenia and frailty have a higher BMR reduction. Therefore, it should be kept in mind that patients with low BMR should alert us to screen sarcopenia and frailty. BMR/BSA may play a role in objective screening to detect sarcopenia in older males. 相似文献6.

Objectives
To investigate the relationship of 4 sarcopenia definitions with long-term all-cause mortality risk in older Australian women.Design
Data from the Perth Longitudinal Study in Aging Women from 2003 to 2013 was examined in this prospective cohort study. The 4 sarcopenia definitions were the United States Foundation for the National Institutes of Health (FNIH), the European Working Group on Sarcopenia in Older People (EWGSOP), and adapted FNIH (AUS-POPF) and EWGSOP (AUS-POPE) definitions using Australian population-specific cut-points [<2 standard deviation (SD)] below the mean of young healthy Australian women. All-cause mortality was captured via linked data systems.Setting and Participants
In total, 903 community-dwelling older Australian women (baseline mean age 79.9 ± 2.6 years) with concurrent measures of muscle strength (grip strength), physical function (timed-up-and-go; TUG) and appendicular lean mass (ALM) were included.Measures
Cox-proportional hazards modeling was used to examine the relationship between sarcopenia definitions and mortality over 5 and 9.5 years.Results
Baseline prevalence of sarcopenia by the 4 definitions differed substantially [FNIH (9.4%), EWGSOP (24.1%), AUS-POPF (12.0%), AUS-POPE (10.7%)]. EWGSOP and AUS-POPE had increased age-adjusted hazard ratios (aHRs) for mortality over 5 years [aHR 1.88 95% confidence interval (CI) (1.24?2.85), P < .01; aHR 2.52 95% CI (1.55?4.09), P < .01, respectively] and 9.5 years (aHR 1.39 95% CI (1.06?1.81), P = .02; aHR 1.94 95% CI (1.40?2.69), P < .01, respectively). No such associations were observed for FNIH or AUS-POPF. Sarcopenia components including weaker grip strength (per SD, 4.9 kg; 17%) and slower TUG (per SD, 3.1 seconds; 40%) but not ALM adjusted-variants (ALM/body mass index or ALM/height2) were associated with greater relative hazards for mortality over 9.5 years.Conclusions/Relevance
Unlike FNIH, the EWGSOP sarcopenia definition incorporating weak muscle strength and/or poor physical function was related to prognosis, as was the regionally adapted version of EWGSOP. Although sarcopenia definitions were not developed based on prognosis, this is an important consideration for globally standardizing the sarcopenia framework. 相似文献7.

Objectives
In Parkinson disease (PD), sarcopenia may represent the common downstream pathway that from motor and nonmotor symptoms leads to the progressive loss of resilience, frailty, and disability. Here we (1) assessed the prevalence of sarcopenia in older adults with PD using 3 different criteria, testing their agreement, and (2) evaluated the association between PD severity and sarcopenia.Design
Cross-sectional, observation study.Setting
Geriatric day hospital.Participants
Older adults with idiopathic PD.Measurements
Body composition was evaluated through dual energy x-ray absorptiometry. Handgrip strength and walking speed were measured. Sarcopenia was operationalized according to the Foundation for the National Institutes of Health, the European Working Group on Sarcopenia in Older Persons, and the International Working Group. Cohen k statistics was used to test the agreement among criteria.Results
Among the 210 participants (mean age 73 years; 38% women), the prevalence of sarcopenia was 28.5%–40.7% in men and 17.5%–32.5% in women. The prevalence of severe sarcopenia was 16.8%–20.0% in men and 11.3%–18.8% in women. The agreement among criteria was poor. The highest agreement was obtained between the European Working Group on Sarcopenia in Older Persons (severe sarcopenia) and International Working Group criteria (k = 0.52 in men; k = 0.65 in women; P < .01 for both). Finally, severe sarcopenia was associated with PD severity (odds ratio 2.30; 95% confidence interval 1.15–4.58).Conclusions
Sarcopenia is common in PD, with severe sarcopenia being diagnosed in 1 in every 5 patients with PD. We found a significant disagreement among the 3 criteria evaluated, in detecting sarcopenia more than in ruling it out. Finally, sarcopenia is associated with PD severity. Considering its massive prevalence, further studies should address the prognosis of sarcopenia in PD. 相似文献8.

Objectives
To assess the occurrence of 3 major adverse outcomes of sarcopenia (ie, physical disabilities, institutionalizations and deaths) observed over a 3-year follow-up in older adults and compare the risk of these outcomes using 5 definitions of sarcopenia.Design
The study is a part of the ongoing SarcoPhAge (for Sarcopenia and Physical Impairment with advancing Age) longitudinal project.Setting and Participants
The SarcoPhAge study follows 534 community-dwelling older adults.Measures
Sarcopenia was defined as low muscle mass plus a decreased muscle function. Data on adverse outcomes were collected yearly during the annual follow-up or with a phone call. The association between baseline sarcopenia and the occurrence of undesirable outcomes was tested using the Cox proportional hazards model or a logistic regression model.Results
A total of 534 subjects were recruited into this prospective cohort (73.5 ± 6.2 years, 60.5% female). After 3 years, 33 participants were lost to follow-up. If no association between baseline sarcopenia and physical disabilities or institutionalizations was highlighted, a higher number of deaths occurred in individuals diagnosed with sarcopenia than in those who were not diagnosed (16.2% vs 4.6%, P value <.001). The probability of death within 3 years when presenting with sarcopenia showed an approximately 3-fold increase compared to subjects without sarcopenia.Conclusion
Over a 3-year period, sarcopenia at baseline was associated with an increased risk of mortality. There were some variations in the ability of different definitions of sarcopenia to predict outcomes. 相似文献9.

Objectives
Deprescribing is effective in addressing concerns relating to polypharmacy in residents of nursing homes. However, the clinical outcomes of deprescribing interventions among residents in nursing homes are not well understood. We evaluated the impact of deprescribing interventions by health care professionals on clinical outcomes among the older residents in nursing homes.Design
Systematic review and meta-analysis of randomized controlled trials. CINAHL, International Pharmaceutical Abstracts, MEDLINE, EMBASE, and Cochrane Library were searched from inception until September 2017; manual searches of reference lists of systematic reviews identified in the electronic search; and online trial registries for unpublished, ongoing, or planned trials. (PROSPERO CRD42016050028).Setting and Participants
Randomized controlled trials in a nursing home setting that included participants of at least 60 years of age.Measures
Falls, all-cause mortality, hospitalization, and potentially inappropriate medication were assessed in the meta-analysis.Results
A total of 41 randomized clinical studies (18,408 residents) that examined deprescribing (defined as either medication discontinuation, substitution, or reduction) in nursing were identified. Deprescribing interventions significantly reduced the number of residents with potentially inappropriate medications by 59% (odds ratio [OR] 0.41, 95% confidence interval [CI] 0.19–0.89). In subgroup analysis, medication review–directed deprescribing interventions reduced all-cause mortality by 26% (OR 0.74, 95% CI 0.65–0.84), as well as the number of fallers by 24% (OR 0.76, 95% CI 0.62–0.93).Conclusions
Compared to other deprescribing interventions, medication review–directed deprescribing had significant benefits on older residents in nursing homes. Further research is required to elicit other clinical benefits of medication review–directed deprescribing practice. 相似文献10.

Objective
The objective of this study was to examine the incidence of new onset depressive symptoms and associated factors over a 1-year period in an older Chinese suburban population.Design
Prospective cohort study.Setting and Participants
The sample comprised 691 Chinese community-dwelling participants (304 men; mean age 67.5 ± 5.7 years) without depressive symptoms at baseline, recruited from Chadian of Tianjin, China.Measures
We had documented detailed information regarding sociodemographics, behavioral characteristics, and medical conditions. Sarcopenia was defined according to the Asian Working Group for Sarcopenia (AWGS) criteria. The outcome was new onset depressive symptoms at 1-year follow-up, defined as a score of ≥11 on the 30-item Geriatric Depression Scale.Results
We found that 83 (12.0%) of the 691 participants without depressive symptoms at baseline had developed depressive symptoms. After multivariate adjustments, it was found that the incidence of new onset depressive symptoms was associated with sarcopenia, type 2 diabetes mellitus, and cardiovascular disease. People with a higher level of muscle mass and better sleep quality were significantly less likely to develop depressive symptoms than their counterparts.Conclusions/Implications
We found that the incidence of depressive symptoms increased with some chronic diseases, such as sarcopenia, type 2 diabetes mellitus, and cardiovascular disease. In addition, muscle mass was the most related protective factor among sarcopenia's 3 basic diagnosis components—muscle mass, muscle strength, and physical performance. Hence, maintaining enough muscle mass could be beneficial in the prevention of depressive symptoms for older adults. 相似文献11.

Objectives
To understand how a heart failure diagnosis and admission health instability predict health transitions and outcomes among newly admitted nursing home residents.Design
Retrospective cohort study of linked administrative data, including the Continuing Care Report System MDS 2.0 for nursing homes, the Discharge Abstract Database for hospitalized patients, and National Ambulatory Care Reporting System to track emergency department visits.Setting and participants
Older adults, aged 65 years and above, admitted to nursing homes in Ontario, Alberta, and British Columbia, Canada, from 2010 to 2016.Measures
Mortality and hospitalization were plotted over 1 year. Multistate Markov models were used to estimate adjusted odds ratios (ORs) for transitions to different states of health in stability, hospitalization, and death, stratified by heart failure diagnosis and by interRAI Changes in Health and End-stage disease Signs and Symptoms (CHESS) score, at 90 days following admission to a nursing home.Results
The final sample included 143,067 residents. Adverse events were most common in the first 90 days. A diagnosis of heart failure predicted worsening health instability, hospitalizations, and mortality. The effect of heart failure on hospitalizations and death was strongest for low baseline health instability (CHESS = 0; OR 1.63, 95% confidence interval (CI) 1.58-1.68, and OR 1.71, 95% CI 1.57-1.86, respectively), versus moderate instability (CHESS = 1-2; OR 1.36, 95% CI 1.32-1.39, and OR 1.48, 95% CI 1.41-1.55), versus high instability (CHESS = 3; OR 1.12, 95% CI 1.03-1.23, and OR 1.21, 95% CI 1.11-1.32). The magnitude of the impact of a heart failure diagnosis was greatest for lower baseline health instability. Residents with the highest degree of health instability were also most likely to die in hospital.Conclusions and implications
A diagnosis of heart failure and health instability provide complementary information to predict transfers, deaths, and adverse outcomes. Clearly identifying these at-risk patients may be useful in targeting interventions in nursing homes. 相似文献12.

Background
Sarcopenia is a major health problem of the older population. The European Working Group on Sarcopenia in Older People (EWGSOP) developed diagnostic criteria for diagnosis of sarcopenia that require assessing muscle mass and strength or physical performance. Recently, however, a rapid screening method SARC-CalF was developed.Objective
The aim of the present study was to validate the SARC-CalF test using EWGSOP sarcopenia diagnostic criteria in a sample of nursing home residents.Methods
Cross-sectional study. A sample of 80 nursing home residents [30% of men; mean age 84.3 (7.9) years]. Sarcopenia was determined as proposed by the EWGSOP diagnostic criteria, whereby muscle mass was measured by bioelectrical impedance, muscle strength by handgrip strength, and physical performance by usual gait speed and a Short Physical Performance Battery score. Sarcopenia was also assessed by the SARC-CalF screening test.Results
A total of 38.7% of sarcopenia was evaluated using EWGSOP diagnostic criteria and 36.2% using the SARC-CalF test. The SARC-CalF demonstrated a sensitivity level of 77.4% and specificity of 89.8%. The area under the receiver operating characteristic curves of SARC-CalF test was 0.84 (95% confidence interval 0.74, 0.94).Conclusions
SARC-CalF could be a useful screening test for sarcopenia in nursing home residents. The incorporation of the test as a basis for sarcopenia screening will provide additional value to current nursing home preventive measures. 相似文献13.

Objectives
To compare the diagnostic value of the 5-component questionnaire that measures strength, assistance walking, rise from a chair, climb stairs, and falls (SARC-F) and SARC-F combined with calf circumference (SARC-CalF) for screening sarcopenia in community-dwelling older adults.Design
A diagnostic accuracy study.Setting
A community in Chengdu, China.Participants
Older adults aged 60 years or older.Measurements
Muscle mass, muscle strength, and physical performance were estimated using a bioimpedance analysis device, handgrip strength, and gait speed, respectively. Four commonly used diagnostic criteria [European Working Group on Sarcopenia in Older People (EWGSOP), Asian Working Group for Sarcopenia (AWGS), International Working Group on Sarcopenia (IWGS), and Foundation for the National Institutes of Health (FNIH) criteria] were applied as the reference standard, separately. The sensitivity/specificity analyses of the SARC-F and SARC-CalF methods were evaluated. The receiver operating characteristics curves and the area under the receiver operating characteristics curves were used to compare the overall diagnostic accuracy of the SARC-F and SARC-CalF for identifying sarcopenia.Results
We included 160 men and 224 women. Based on the 4 diagnostic criteria, the prevalence of sarcopenia ranged from 11.7% to 25.0%. Using the AWGS criteria as the reference standard, the SARC-CalF had a sensitivity of 60.7% and a specificity of 94.7% in the whole study population, whereas the SARC-F had a sensitivity of 29.5% and a specificity of 98.1%. The area under the receiver operating characteristics curves for SARC-CalF and SARC-F were 0.92 (95% confidence interval 0.89?0.94) and 0.89 (95% confidence interval 0.86?0.92), respectively (P = .003). We obtained similar results when using the other 3 criteria as the reference standard. Subgroup analyses revealed similar results in both men and women.Conclusions
SARC-CalF significantly improves the sensitivity and overall diagnostic accuracy of SARC-F for screening sarcopenia in community-dwelling older adults. 相似文献14.

Background
Premenstrual symptoms are experienced by up to 95% of women, and few treatments are available. Previous studies suggest that 25-hydroxyvitamin D (25(OH)D) may be associated with the severity of premenstrual symptoms, but the findings have been inconclusive.Objective
The objective of this study was to determine whether vitamin D status is associated with the severity of individual premenstrual symptoms.Design/participants
Cross-sectional analysis of 998 women aged 20 to 29 years recruited at the University of Toronto campus from 2004 through 2010.Main outcome measures
Participants provided data on their premenstrual symptoms in a premenstrual symptom questionnaire. Fasting overnight blood samples were collected, and plasma 25(OH)D was measured. Participants with plasma 25(OH)D concentrations <20 ng/mL were considered to have inadequate vitamin D status, and those with ≥20 ng/mL, adequate vitamin D status.Statistical analyses performed
Multinomial logistic regressions were used to calculate the odds ratio (OR) and 95% confidence interval for the associations between vitamin D status and the severity of 15 premenstrual symptoms. Adjustments were made for age, body mass index, ethnicity/race, physical activity, hormonal contraceptive use, season of blood draw, use of analgesics, and calcium intake.Results
Compared with participants with adequate vitamin D status, those with inadequate vitamin D status had an increased risk (odds ratio [OR]; 95% CI) of experiencing the following mild symptoms: confusion (OR=1.72; 95% CI, 1.14 to 2.59) and desire to be alone (OR=1.47; 95% CI; 1.03 to 2.10), as well as the following moderate/severe symptoms: cramps (OR=1.50; 95% CI, 1.02 to 2.21), fatigue (OR=1.51; 95% CI, 1.04 to 2.21), anxiety (OR=1.63; 95% CI, 1.02 to 2.63), confusion (OR=2.23; 95% CI, 1.18 to 4.21), and sexual desire (OR=1.65; 95% CI, 1.09 to 2.51). Vitamin D status was not associated with other premenstrual symptoms (acne, bloating, mood swings, increased appetite, headache, clumsiness, insomnia, depression, or nausea).Conclusion
Findings suggest that inadequate vitamin D status may be associated with increased severity of some, but not all, premenstrual symptoms. 相似文献15.

Background
Evidence from epidemiologic studies has been inconsistent regarding the role of vitamin E in cancer incidence risk.Objective
The aim of this study was to evaluate the prospective association between baseline plasma vitamin E levels and subsequent cancer risk in Chinese adults with hypertension, and to identify effect modifiers.Design
A nested, case–control study was conducted from 20,702 hypertensive participants in the China Stroke Primary Prevention Trial, a randomized, double-blind, controlled trial, conducted from May 2008 to August 2013.Participants
The current study included 229 new cancer cases and 229 controls matched for age (±1 year), sex, treatment group, and study site.Main outcome measures
Plasma vitamin E was measured by liquid chromatography with tandem quadrupole mass spectrometers and plasma selenium was measured by inductively coupled plasma mass spectrometry using Thermo Fisher iCAP Q ICP-MS.Statistical analyses
Odds ratios (OR) of cancer in relation to plasma concentrations of vitamin E were calculated using conditional logistic regression models.Results
Median follow-up duration was 4.5 years. Overall, vitamin E was not associated with subsequent risk of total cancer (per 1-mg/L [2.3 μmol/L] increase: OR 1.01, 95% CI 0.93 to 1.09) and non-gastrointestinal cancer (OR 1.10, 95% CI 0.98 to 1.24). However, there was a significant, inverse association between vitamin E and gastrointestinal cancer (OR 0.86, 95% CI 0.75 to 0.99), particularly esophageal cancer (OR 0.67, 95% CI 0.48 to 0.95). Moreover, high vitamin E decreased the risk of total cancer (OR 0.91, 95% CI 0.84 to 0.99) and gastrointestinal cancer (OR 0.83, 95% CI 0.73 to 0.95) among patients with high selenium levels (median≥83.7 μg/L [1.1 μmol/L]), and increased the risk of total cancer (OR 1.13, 95% CI 1.00 to 1.26) and non-gastrointestinal cancer (OR 1.25, 95% CI 1.03 to 1.50) among those with low selenium levels (<83.7 μg/L [1.1 μmol/L]).Conclusions
This study suggests that higher levels of plasma vitamin E are associated with reduced risk of gastrointestinal cancer. High vitamin E decreased the risk of total cancer among patients with high selenium levels, but increased the risk of total cancer among those with low selenium levels. 相似文献16.

Background
Dietary interventions are effective prevention and treatment strategies for chronic diseases; however, they require extensive commitment, time, and resources. Dietary mobile applications (apps) have gained popularity and are thus being incorporated into dietary management.Objective
The aim of this review is to assess the effects of the use of dietary mobile apps on nutritional outcomes in adults with chronic diseases.Methods
A systematic review was conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using MEDLINE, PubMed, Embase, and CINAHL databases. The protocol was registered on PROSPERO. Intervention studies evaluating the nutritional outcomes of dietary apps, published in English between January 1, 2007 and November 15, 2017 were included. The methodological quality of included articles was assessed via the Academy of Nutrition and Dietetics’ Quality Criteria Checklist: Primary Research. Heterogeneity was confirmed using the I2 index and a random-effects meta-analysis was performed for randomized controlled trials. Estimates of the pooled mean difference were calculated for app usage compared to no app usage.Main outcomes measure
Nutritional outcomes, categorized as food-/nutrition-related, anthropometric measurements, pertinent clinical/biochemical data, and nutrition-focused physical findings, were extracted from the included intervention studies.Results
Upon completion of the searches, 18,649 articles were identified, and data were extracted from 22 articles. Pooled estimates showed a significantly greater decrease in weight (–2.45 kg, 95% CI –3.33 to –1.58 kg; P<0.001; I2=96.2%, 95% CI 95% to 97%), waist circumference (–2.54 cm, 95% CI –3.34 to –1.73 cm; P<0.001; I2=88.3%, 95% CI 67% to 96%), and energy intake (–149.52 kcal, 95% CI –215.78 to –83.27 kcal; P<0.001; I2=0% CI 0% to 90%) when an app was used compared to control.Conclusions
The findings of this systematic review and meta-analysis indicate that dietary mobile apps are effective self-monitoring tools, and that their use results in positive effects on measured nutritional outcomes in chronic diseases, especially weight loss. 相似文献17.

Objectives
To examine the potential added value of a simple 5-item questionnaire for sarcopenia screening (SARC-F) to the Fracture Risk Assessment Tool (FRAX) for hip fracture risk prediction, in order to identify at-risk older adults for screening with dual-energy x-ray absorptiometry (DXA).Design
A prospective cohort study.Setting and participants
Two thousand Chinese men and 2000 Chinese women aged 65 years or older were recruited from local communities and were prospectively followed up for about 10 years.Measures
Areal bone mineral density (BMD) of hip and lumbar spine were measured by DXA at baseline. Ten-year FRAX probability of hip fracture was calculated using the baseline risk factors. Information from the baseline questionnaire was extracted to calculate a modified SARC-F score. The independent predictive values of SARC-F and FRAX questionnaire were evaluated using multivariate survival analysis. The added predictive values of SARC-F to FRAX for pre-DXA screening were examined.Results
During the follow-up, 63 (3.2%) men and 69 (3.5%) women had at least 1 incident hip fracture. SARC-F had an independent value of FRAX for hip fracture risk prediction, with an adjusted hazard ratio [95% confidence interval (CI)] of 1.24 (1.02, 1.52) and 1.15 (0.99, 1.13) in men and women, respectively. Compared with using FRAX, using SARC-F in conjunction with FRAX made the sensitivity for prediction rise from 58.7% to 76.2% in men and from 69.6% to 78.3% in women, with a nondecreased area under receiver operating characteristic curve of 0.67. Prescreening using FRAX in conjunction with SARC-F could save more than half of the DXA assessment than with no prescreening.Conclusions/Implications
SARC-F is associated with a modest increase in hip fracture risk, especially in men. Conjoint evaluation for sarcopenia in addition to FRAX screening may help identify older adults at higher risk of hip fracture for more intensive screening and/or preventive interventions. 相似文献18.

Introduction
Frailty and sarcopenia are correlates of musculoskeletal aging that represent a state of vulnerability increasing the risk of negative health outcomes. Standardized definitions are lacking for both, and sometimes both concepts are used interchangeably. However, no large study has assessed the coexistence of these 2 entities in a cohort of older community-dwelling people.Methods
Data were taken from the Toledo Study of Healthy Aging (TSHA), a study of community-dwelling elderly (≥65 years). The study population consists of 1611 participants with frailty and sarcopenia assessments. For sarcopenia, we used 3 criteria: European Working Group on Sarcopenia in Older People (EWGSOP), the Foundation for the National Institutes of Health (FNIH), and the FNIH fitted to the cut-off points of our population [standardized FNIH (sFNIH)]. Frailty was assessed according to the Fried criteria with cut-off points adjusted to our population. We used logistic regression to assess the relationship between sarcopenia and frailty and measures of diagnostic accuracy to evaluate the potential use of sarcopenia as a diagnostic marker for frailty.Results
The mean age of the population was 75.42 years (±5.86). Overall, 72 (4.5%) were frail. In addition, 352 (21.8%), 332 (20.6%), and 453 (28.1%) participants were considered sarcopenic according to the EWGSOP, FNIH, and sFNIH criteria, respectively. The prevalence of frailty among those with sarcopenia was 8.2% (29/352), 15.7% (52/332), and 10.4% (47/453). Moreover, among frail people, the prevalence of sarcopenia was 40.27%, 72.2%, and 65.3% according to the used criteria. Sarcopenia showed a low sensitivity (<10%) but high specificity (>97%) for the diagnosis of frailty, with a low intercorrelation (Cramer V = 0.16, 0.40, and 0.30) between the 3 criteria and frailty. Using multivariate logistic regression, frailty was associated with sarcopenia according to EWGSOP [odds ratio (OR) = 1.67, 95% confidence interval (CI) = 0.95, 2.96], FNIH (OR = 10.61, 95% CI = 5.8, 19.4), and sFNIH (OR = 6.63, 95% CI =3.5, 12.53).Conclusion
Frailty and sarcopenia are distinct but related conditions. Sarcopenia is not a useful clinical biomarker of frailty, but its absence might be useful to exclude frailty. 相似文献19.

Objectives
Protein and energy malnutrition and unintended weight loss are frequently reported in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). Possible underlying mechanisms include increased energy expenditure, altered uptake of nutrients, a reduced nutritional intake, or a combination of these 3. We aimed at systematically reviewing the literature to examine potential differences in energy and protein intake in patients with MCI and AD compared to controls as a possible mechanism for unintended weight loss.Design
Systematic review and meta-analysis.Setting
PubMed and Cochrane Electronic databases were searched from inception to September 2017 for case control studies.Participants
Patients with MCI or AD compared to cognitive healthy controls, all adhering to a Western dietary pattern.Measurements
Energy and protein intake.Results
The search resulted in 7 articles on patients with AD versus controls, and none on patients with MCI. Four articles found no differences in energy and protein intakes, 1 found higher intakes in patients with AD, and 1 article found lower intakes in patients with AD compared to controls. One article reported on intakes, but did not test differences. A meta-analysis of the results indicated no difference between patients with AD and controls in energy [?8 kcal/d, 95% confidence interval (CI): ?97, 81; P = .85], or protein intake (2 g/d, 95% CI: ?4, 9; P = .47). However, heterogeneity was high (I2 > 70%), and study methodology was generally poor or moderate.Conclusion
Contrary to frequently reported unintended weight loss, our systematic review does not provide evidence for a lower energy or protein intake in patients with AD compared to controls. High heterogeneity of the results as well as of participant characteristics, setting, and study methods was observed. High-quality studies are needed to study energy and protein intake as a possible mechanism for unintended weight loss and malnutrition in both patients with MCI and AD. 相似文献20.
