Zhang J, Wang N, Li J, Wang Y, Xiao Y, Sha T. The Diagnostic Accuracy and Cutoff Value of Phase Angle for Screening Sarcopenia: A Systematic Review and Meta-Analysis. J Am Med Dir Assoc 2024:105283. [PMID: 39326856 DOI: 10.1016/j.jamda.2024.105283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 08/21/2024] [Accepted: 08/21/2024] [Indexed: 09/28/2024]
Abstract
OBJECTIVES Phase angle (PhA) declines with age and is a reliable marker for muscle function, making it a potential screening indicator for sarcopenia. However, studies examined the reliability and validity of PhA for detecting sarcopenia, yielding inconsistent results. This meta-analysis aimed to evaluate the accuracy and cutoff value of PhA for screening sarcopenia and examine the potential confounding factors. DESIGN This is a meta-analysis. SETTING AND PARTICIPANTS PubMed, Embase, and Cochrane Library were searched up to September 18, 2023.Eighteen studies (6184 participants) were included reporting the diagnostic accuracy of PhA for screening sarcopenia. METHODS Pooled accuracy (ie, the computed area under the curve value [AUC]) and cutoff value interval for screening sarcopenia were estimated using a random-effects model. Meta-regression analyses were conducted to identify sources of heterogeneity. RESULTS The AUC value was 0.81. Pooled sensitivity and specificity were 80% and 70%. The calculated 95% CI of the cutoff value of PhA for screening sarcopenia falls between 4.54° and 5.25°. The results of meta-regression analyses showed that ethnicity, body mass index (BMI), health status, and diagnostic criteria were the main factors affecting the diagnostic accuracy for screening sarcopenia (with all P values < 0.01). CONCLUSION AND IMPLICATIONS PhA may serve as a robust screening tool for sarcopenia, and the recommended cutoff interval falls between 4.54° and 5.25°. Ethnicity, BMI, health status, and diagnostic criteria can affect PhA's efficacy in sarcopenia screening.

Abstract
[Purpose] This study aimed to clarify the association between phase angle (PhA) and the level of independence in daily living among institutionalized super older females requiring nursing care. [Participants and Methods] This three-facility cross-sectional study enrolled 173 nursing home residents (mean age 91.0 years, standard deviation 4.9 years) divided into five groups, from 80+ to 100+ years of age, in 5-year increments. PhA, skeletal muscle mass index, body fat percentage, body mass index, and Barthel Index were measured in the five groups. We measured the relationship between age and PhA and analyzed partial correlation coefficients using these items. The adjusted variables differed significantly among the five groups. [Results] The overall PhA was 2.91 degrees, with a 2.36-degree PhA in patients aged >100 years. Age differences were found between the PhA and the Barthel Index. A significant correlation (0.66) was identified between the PhA and the Barthel Index. The age-adjusted partial correlation coefficient between the PhA and the Barthel Index was 0.56, indicating a moderately significant positive correlation. [Conclusion] This study identified an association between PhA and independence in daily living among female nursing home residents aged 80-107 years, indicating that the PhA is an excellent indicator of physical condition.

[PMID: 38600867 DOI: 10.4235/agmr.24.0017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 04/04/2024] [Indexed: 04/12/2024] Open
Abstract
BACKGROUND Sarcopenia negatively affects the short-term prognosis of hospitalized older adults. However, no evidence currently supports a direct relationship between sarcopenia and readmission among individuals who have experienced an acute stroke. Therefore, we investigated whether sarcopenia is associated with readmission after discharge. METHODS This retrospective cohort study included patients who had experienced acute stroke. Sarcopenia was defined as the coexistence of low skeletal muscle mass index (SMI) and grip strength. We applied the log-rank test and Cox proportional hazards regression analysis to analyze whether sarcopenia, low SMI, and low grip strength were associated with readmission within 6 months. RESULTS Among 228 included patients (mean age, 72.8 years; 146 males), the prevalence of sarcopenia was 24.6% (n=56; male 17.8%; female 36.6%). Cox proportional hazards regression analysis using the propensity score as a covariate revealed that sarcopenia (hazard ratio [HR]=7.21; 95% confidence interval [CI] 1.45-35.8; p=0.016) and low skeletal muscle mass (HR=7.40; 95% CI 1.14-48.1; p=0.036), but not low grip strength (HR=1.42; 95% CI 0.281-7.21; p=0.670), were significantly associated with readmission for stroke within 6 months. CONCLUSIONS Sarcopenia was negatively associated with readmission within 6 months of stroke onset in patients in Japan who had experienced an acute stroke. These findings suggest that the identification of sarcopenia may facilitate prognostic prediction from the acute stage and intervention(s) to prevent rehospitalization.

Abstract
BACKGROUND The prevalence of stroke-related sarcopenia has been noted; however, epidemiological data and interventions that increase or reduce the incidence of stroke-related sarcopenia remain lacking. METHODS Studies on stroke-related sarcopenia were included in association or interventional analyses. All analyses were performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two evaluators independently extracted the data. RESULTS Female stroke patients had a higher preference for sarcopenia than male patients (pooled odds ratio [OR] = 0.670, 95 % CI 0.533-0.842, p = 0.001). Although stroke patients without drug use have improved skeletal muscle mass index (SMI) (MD = 0.272, 95 % CI 0.087-0.457, p = 0.004), handgrip strength (HGS) was not significantly altered (MD = -0.068, 95 % CI -0.221-0.076, p = 0.354). Stroke patients with nutrient interventions have improved SMI (MD = -0.354, 95 % CI -0.635- -0.073, p = 0.014) and HGS (MD = -0.394, 95 % CI -0.678- -0.111, p = 0.006); the synergistic effect of rehabilitation exercise has not been ruled out. Whether a sex difference exists in these interventions remains to be investigated. The underlying pathological mechanisms and potential therapeutic strategies for this disease are discussed. CONCLUSION Sex difference, proteostasis, and mitochondrial function may impact the incidence of stroke-related sarcopenia. Understanding the underlying pathological mechanisms and potential therapeutic targets for this disease will provide new insights into disease treatment, prevention, and drug development.

Abstract
BACKGROUND This study aimed to determine whether an increased trunk muscle quality index (TMQI) is associated with activities of daily living (ADL) in patients ≥ 65 years of age with cerebral infarction in a convalescent rehabilitation ward. METHODS This retrospective observational study included patients aged ≥ 65 years who were admitted for post-stroke rehabilitation in Okinawa, Japan, between May 2018 and December 2022. The TMQI was calculated at admission and discharge using bioelectrical impedance analysis. Patients were divided into two groups based on the change in the TMQI during hospitalization: increase-in-TMQI and no-increase-in-TMQI groups. Multiple regression analysis was employed to explore the impact of increased TMQI on functional independence measure (FIM) -motor gain. RESULTS We included a total of 315 patients (79.1 ± 7.9 years of age, 51.7% men) in our analyses. Over half (165 [52.4%]) of the patients exhibited an increase in TMQI scores, and 150 (47.6%) patients did not exhibit an increase. No significant difference was observed in motor FIM score and motor FIM gain at admission and discharge between the groups with and without increased TMQI. Increased TMQI was independently associated with increased FIM-motor gain (adjusted R2 = 0.340 and R2 = 0.357, coefficient = 1.736, 95% confidence interval: 0.52-2.95, P = 0.005). CONCLUSIONS The results of this study suggest that increased TMQI has a positive effect on the recovery of physical function in patients with stroke. Further prospective studies are needed to elucidate the relationship between increased TMQI and ADL.

Abstract
BACKGROUND The short-term prognosis of stroke patients is mainly influenced by the severity of the primary disease at admission and the trend of disease development during the acute phase (1-7 days after admission). OBJECTIVE The aim of this study is to explore the relationship between the bioelectrical impedance analysis (BIA) parameter trajectories during the acute phase of stroke patients and their short-term prognosis, and to investigate the predictive value of the prediction model constructed using BIA parameter trajectories and clinical indicators at admission for short-term prognosis in stroke patients. METHODS A total of 162 stroke patients were prospectively enrolled, and their clinical indicators at admission and BIA parameters during the first 1-7 days of admission were collected. A Group-Based Trajectory Model (GBTM) was employed to identify different subgroups of longitudinal trajectories of BIA parameters during the first 1-7 days of admission in stroke patients. The random forest algorithm was applied to screen BIA parameter trajectories and clinical indicators with predictive value, construct prediction models, and perform model comparisons. The outcome measure was the Modified Rankin Scale (mRS) score at discharge. RESULTS PA in BIA parameters can be divided into four separate trajectory groups. The incidence of poor prognosis (mRS: 4-6) at discharge was significantly higher in the "Low PA Rapid Decline Group" (85.0%) than in the "High PA Stable Group " (33.3%) and in the "Medium PA Slow Decline Group "(29.5%) (all P < 0.05). In-hospital mortality was the highest in the "Low PA Rapid Decline Group" (60%) compared with the remaining trajectory groups (P < 0.05). Compared with the prediction model with only clinical indicators (Model 1), the prediction model with PA trajectories (Model 2) demonstrated higher predictive accuracy and efficacy. The area under the receiver operating characteristic curve (AUC) of Model 2 was 0.909 [95% CI 0.863, 0.956], integrated discrimination improvement index (IDI), 0.035 (P < 0.001), and net reclassification improvement (NRI), 0.175 (P = 0.031). CONCLUSION PA trajectories during the first 1-7 days of admission are associated with the short-term prognosis of stroke patients. PA trajectories have additional value in predicting the short-term prognosis of stroke patients.

Abstract
AIM This retrospective cohort study investigated the relationship between sarcopenia and Activities of Daily Living capacity after discharge from convalescent rehabilitation wards. METHODS We included consecutive patients discharged from three convalescent rehabilitation wards in a hospital in Japan between December 2018 and October 2020. Sarcopenia was diagnosed based on the criteria of the 2019 Asian Working Group for Sarcopenia, utilizing skeletal muscle mass index and handgrip strength. Statistical analyses were carried out separately for men and women. The primary outcome was a higher motor domain (motor Functional Independence Measure [mFIM]) and a higher cognitive domain (cognitive Functional Independence Measure [cFIM]) of the FIM score 1 month after discharge. The secondary outcomes were higher mFIM and cFIM scores 6 months after discharge, analyzed using binary logistic regression. RESULTS Among 305 participants (mean age 70.0 years, 148 men), 93 were identified as having sarcopenia. The prevalence of sarcopenia was 16% for outpatient rehabilitation services, 59% for home-visit rehabilitation services and 50% for older adult day care. Logistic regression analyses showed that sarcopenia at discharge was not an independent variable for mFIM at 1 month (odds ratio [OR] 20, 95% confidence interval [CI] 0.31-1300 for men, OR 0.51, 95% CI 0.11-2.4 for women) and cFIM (OR 0.63, 95% CI 0.10-3.8 for men, OR 5.3, 95% CI 0.81-34 for women). At 6 months, sarcopenia at discharge was not an independent variable for mFIM (OR 0.30, 95% CI 0.02-3.6 for men, OR 0.40, 95% CI 0.06-2.5 for women) and cFIM (OR 0.16, 95% CI 0.01-2.4 for men, OR 0.00, 95% CI 0.00-1.1 for women). CONCLUSIONS Sarcopenia at the time of discharge from convalescent rehabilitation wards does not independently predict FIM 1 month or 6 months after discharge. Geriatr Gerontol Int 2024; 24: 715-721.

Abstract
OBJECTIVES To determine the relationship between bioelectrical impedance analysis (BIA) parameters, including the extracellular water-to-total body water ratio (ECW/TBW), and the activities of daily living (ADL) improvement, in patients who experienced acute stroke. MATERIALS AND METHODS This retrospective cohort study included 307 patients (mean age, 72 years; 39 % female) who experienced acute stroke and were admitted to the stroke unit of the Nippon Medical School Hospital (Bunkyo-ku, Tokyo, Japan) between April 2021 and March 2022. The Functional Independence Measure (FIM) was assessed at initial rehabilitation and discharge, and FIM effectiveness was calculated as ADL improvement in the participating acute care hospitals. BIA markers included the skeletal muscle mass index (SMI), phase angle (PhA), and ECW/TBW. Multiple linear regression models were used to estimate the relationship between the FIM effectiveness and each BIA marker. RESULTS The mean (±SD) FIM effectiveness was 0.45 ± 0.36. The proportions of low SMI (male, <7.0 kg/m2; female, <5.7 kg/m2) and low PhA (male <5.36 degrees, female <3.85 degrees), were 48.9 % and 43.3 %, respectively. In addition, the proportions of of low (<0.36), normal (0.36-0.40), and high (>0.4) ECW/TBW ratios were 1.3 %, 78.5 %, and 20.2 %, respectively. After adjustments for demographic and clinical variables, low PhA, low ECW/TBW, and high ECW/TBW were all significantly associated with FIM effectiveness (P < 0.05), with β coefficients of -0.126, -0.089, and -0.117, respectively. CONCLUSIONS Low and High ECW/TBW and low PhA levels were negatively correlated with improvements in ADL. The ECW/TBW ratio may be an additional indicator of rehabilitation trainability in patients who experience acute stroke.

Abstract
BACKGROUND & AIMS This study aimed to investigate the effects of low phase angle (PhA) on functional status and discharge disposition during the acute phase in older patients with acute stroke. METHODS We included consecutive patients who experienced acute stroke between October 2021 and December 2022. The exclusion criteria included: age<65 years, admission from other than home, death during hospitalization, inability to measure bioelectrical impedance analysis owing to implantation, and missing data. We defined low PhA (<5.28° for male and <4.62° for female) and categorized them into the low PhA group and normal group. The clinical outcomes were functional independence by the modified Rankin Scale (mRS) score (0-2, independence; 3-5, nonindependence) and discharge disposition (home or others). We used multivariate logistic regression analysis to examine the effect of low PhA on the mRS score at discharge and discharge disposition. RESULTS Ultimately, a total of 205 patients were included in this analysis. More patients in the low PhA group were unable to be independent (27.7% vs. 66.7%, P < 0.001) and were unable to be discharged home (53.4% vs. 82.5%, P < 0.001) than in the normal group. Logistic regression analysis of the mRS scores showed that baseline low PhA decreased the likelihood of functional independence (odds ratio [OR] = 0.275, P = 0.003) and home discharge (OR = 0.378, P = 0.044). CONCLUSIONS Low PhA is a risk factor for low functional status at hospital discharge; it decreases the likelihood of home discharge in older patients with acute stroke.

Abstract
Objectively measured physical activity volume serves as a predictive factor for functional recovery in patients with stroke. Malnutrition, a frequent complication of stroke, may influence the relationship between physical activity and functional recovery. This study aimed to examine the association between physical activity volume and functional recovery in patients with stroke, stratified by their nutritional status. This multicenter prospective observational study included 209 patients with stroke admitted to two Japanese convalescent rehabilitation hospitals. Participants were categorized based on the geriatric nutritional risk index (GNRI) at admission [≥92, high GNRI group ( n = 133); <92, low GNRI group ( n = 76)]. Physical activity levels were measured as the duration of total physical activity (TPA), which is the sum of light-intensity physical activity and moderate-to-vigorous physical activity, using a triaxial accelerometer during the first 7 days after admission. Outcome measures are represented as the relative gain of the motor score on functional independence measure (M-FIM effectiveness) during the first month after admission. The multiple regression analysis, adjusting for age, sex, comorbidity, onset to admission intervals, motor paralysis, initial M-FIM, and cognitive FIM, showed that the duration of TPA in the first 7 days was significantly associated with the M-FIM effectiveness over the first month in both low GNRI [ B = 0.12, 95% confidential intervals (CI) = 0.01; 0.24, P = 0.049] and high GNRI group ( B = 0.11, 95% CI = 0.01; 0.21, P = 0.027). This study demonstrates a positive predictive association between early TPA level and functional recovery in stroke patients, irrespective of their nutritional status.

Abstract
BACKGROUND This study aimed to determine whether changes in phase angle during rehabilitation are associated with clinical outcomes such as activities of daily living (ADL), skeletal muscle mass index (SMI), and strength in patients with osteoporotic fractures. METHODS This retrospective observational study included patients with osteoporotic fractures admitted to convalescent rehabilitation wards. Changes in phase angle were defined as the difference between the phase angle values at discharge and on admission. The primary outcome was the Functional Independence Measure motor (FIM-motor) score at discharge. The secondary outcomes were SMI and handgrip strength at discharge. We used multivariate analysis to adjust for confounding factors and examine the association between changes in the phase angle and outcomes. RESULTS We analyzed a total of 115 patients (97 women, mean age of 81.0±10.0 years), with a median change in phase angle of 0° during hospitalization. We observed increased phase angles in 49 patients (43%), with a median increase of 0.2°. Multiple regression analysis showed that changes in phase angle were independently associated with FIM-motor score at discharge (β=0.238, p=0.027). Changes in phase angle were not significantly associated with SMI (β=0.059, p=0.599) or handgrip strength (β=-0.032, p=0.773) at discharge. CONCLUSION An increased phase angle during rehabilitation was positively associated with ADL improvement in patients with osteoporotic fractures. These findings may help clinicians make informed decisions regarding patient care and treatment strategies for better outcomes.

Abstract
AIM How possible sarcopenia affects functional prognosis in patients with premorbid disability remains unclear. This study aimed to compare and investigate the impact of possible sarcopenia at admission on functional outcomes at discharge in patients with acute stroke with and without premorbid disability. METHODS This cohort study enrolled patients who were consecutively admitted to a single center for acute stroke. Calf circumference and grip strength were measured within 7 days of admission, and possible sarcopenia was determined using the Asian Working Group for Sarcopenia 2019 criteria. The Functional Independence Measure (FIM) score at discharge during the acute phase was the primary outcome. To examine the impact of possible sarcopenia on FIM scores at discharge, patients were divided into two groups according to being with or without premorbid disability according to the modified Rankin Scale, and multiple linear regression analysis was performed in each group. RESULTS This study included 456 patients with acute stroke (median age, 80 years). In the premorbid-disability group (n = 166), possible sarcopenia was present in 140 patients (84%). Patients without possible sarcopenia had significantly higher FIM scores at discharge compared with those with possible sarcopenia (P < 0.001). However, multiple linear regression analysis showed that possible sarcopenia was not associated with FIM scores at discharge in the premorbid-disability group (β = -0.054, P = 0.346). CONCLUSIONS The results of this study demonstrated that a high rate of possible sarcopenia was observed in patients with stroke with premorbid disability; however, this did not affect functional prognosis.

Abstract
BACKGROUND Phase angle, which is associated with cellular health, has attracted attention as a noninvasive and objective method for nutritional assessment. However, the association between malnutrition and phase angle in older inpatients with hip fractures has not been reported. Therefore, this study investigated this association in older inpatients (aged ≥65 years) with hip fractures and determined the cutoff phase angle for determining malnutrition. METHODS This cross-sectional study retrospectively analyzed the data of 96 inpatients with hip fractures who were hospitalized in rehabilitation units after surgery (male, 29.4%; mean age, 82.4±6.2 years). Nutritional status was assessed using the Geriatric Nutritional Risk Index (GNRI), with malnutrition defined as a GNRI ≥98. Bioelectrical impedance analysis was used to measure phase angles. RESULTS The phase angle was associated with malnutrition (B=-1.173; odds ratio=0.310; 95% confidence interval 0.58-0.83; p=0.015). The area under the receiver operating characteristic curve was 0.71. The cutoff phase angle for malnutrition was 3.96° (sensitivity=0.85, specificity=0.63). CONCLUSION Phase angle could be an indicator of malnutrition in older inpatients with hip fractures. Our findings will help formulate rehabilitation strategies for these patients.

Muscle quality improvement in subacute post-stroke patients after rehabilitation: Usefulness of segmental phase angle from bioelectrical impedance analysis. Clin Nutr 2024; 43:224-231. [PMID: 38096627 DOI: 10.1016/j.clnu.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 11/27/2023] [Accepted: 12/01/2023] [Indexed: 12/26/2023]
Abstract
BACKGROUND & AIMS During stroke rehabilitation, the whole-body Phase Angle (PhA) from Bioelectrical Impedance Analysis (BIA) is measured to assess whole-body muscle quality, which reflects cellular integrity and function. The segmental BIA is a valuable method for assessing the body composition of specific body segments, such as the arms, legs, and hemisoma. After a stroke insult, patients frequently experience hemiparesis, and segmental PhA from segmental BIA appears to be an appropriate parameter for examining the muscle quality of affected and unaffected limbs separately. This study aims to investigate whether segmental PhA is more informative than whole-body PhA in (a) assessing the deterioration of muscle quality in post-stroke patients and (b) monitoring its recovery following rehabilitative treatment. METHODS This longitudinal study recruited subacute post-stroke patients who were admitted to our rehabilitation center. At admission, demographic, anamnestic, and clinical information, such as the presence of comorbidities, were recorded. BIA was used to evaluate the whole-body PhA and segmental PhA of the affected and unaffected hemisoma, arms, and legs at admission (T0) and after a six-week rehabilitation program (T1). The modified Barthel Index (mBI), Fugl-Meyer Assessment for the Upper Extremity (FMA-UE), and Motricity Index of the Upper (MI-UE) and Lower (MI-LE) Extremities were evaluated at T0 and T1 to determine the patient's Activity of Daily Living (ADL) performance, upper limb motor performance, and upper and lower limb muscle strength, respectively. RESULTS We evaluated segmental and whole-body BIA in 70 subacute post-stroke patients (women n = 34, ischemic n = 56, mean age 70 ± 11) at T0 and T1. Whole-body PhA values of the patients were below the normal range. Considering segmental data, the affected hemisoma, arm, and leg had considerably lower PhA values as compared to the unaffected body segments. Furthermore, at T1, the PhA values of all affected body segments improved, while those of the unaffected ones and whole-body PhA did not. At both T0 and T1, the segmental PhA values of the affected body segments showed to be related with all clinical outcome measures, while whole-body PhA correlated only with mBI. CONCLUSIONS This study emphasizes the significance of measuring segmental PhA in hemiparetic subacute stroke patients undergoing rehabilitation treatment. Segmental PhA is a more accurate parameter to evaluate rehabilitation treatment in patients with hemiparesis because it can distinguish affected from unaffected body segments, hence facilitating accurate monitoring of muscle quality improvements resulting from a rehabilitation program.

Is Phase Angle Useful in Screening for Sarcopenia in Patients with Hematologic Malignancies? Nutr Cancer 2023; 76:121-127. [PMID: 37987672 DOI: 10.1080/01635581.2023.2283933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 11/10/2023] [Accepted: 11/10/2023] [Indexed: 11/22/2023]
Abstract
The purposes of this study were to investigate the relationship between sarcopenia and phase angle (PhA), and to examine whether PhA cutoff values can be used to identify sarcopenia in patients with hematologic malignancies. The study population comprised 108 patients with hematologic malignancies who were admitted for chemotherapy, and were undergoing rehabilitation for exercise therapy. The diagnostic criteria for sarcopenia were determined according to the Asian Working Group for Sarcopenia 2019. Muscle strength, endurance, and body composition (including PhA), were assessed. Logistic regression and receiver operating characteristic (ROC) curve analyses were performed to investigate associations between sarcopenia and PhA, and to determine cutoff values. Sarcopenia was found in 17.6% of the participants. PhA was significantly associated with sarcopenia (p < 0.01). The areas under the curve were 0.84 for the males and 0.87 for the females, and the cutoff values were 4.75° for the males (sensitivity 69%, specificity 83%) and 3.95° for the females (sensitivity 78%, specificity 85%). Our results suggest that PhA, which can be measured noninvasively, objectively, and rapidly, can be used as a screening tool for sarcopenia in patients with hematologic malignancies.

Abstract
PURPOSE The phase angle (PhA) is a simple index that reflects nutritional status and muscle quality. This study aimed to investigate the association between PhA changes and activities of daily living (ADL), muscle strength, and muscle mass in patients with acute stroke. METHODS This retrospective, observational, cross-sectional study included patients hospitalized for acute stroke. The primary outcome was functional independence measure (FIM) of motor gain. The secondary outcomes were changes in handgrip strength and skeletal muscle mass index (SMI) during hospitalization. Multivariate analysis was used to examine whether PhA changes were associated with outcomes, after adjusting for potential confounders. RESULTS Hundred and sixty one subjects (mean age 74.6 years, 92 men) were included in the study. Multivariate analysis showed that PhA change was significantly and positively correlated with the gain in FIM motor scores, both for men (β = 0.634, p < 0.001) and women (β = 0.660, p < 0.001). Furthermore, there were significant associations between PhA change and changes in handgrip strength for men (β = 0.222, p = 0.030) and women (β = 0.491, p < 0.001), as well as SMI for men (β = 0.556, p < 0.001) and women (β = 0.290, p = 0.025). CONCLUSIONS An increased phase angle was positively associated with ADL, muscle strength, and muscle mass at discharge in patients with acute stroke.

Abstract
BACKGROUND & AIMS Evidence is limited concerning the association between bioimpedance analysis-derived phase angle and sarcopenic obesity. This study examined this association in patients who underwent convalescent rehabilitation after stroke. METHODS This cross-sectional study included hospitalized patients with post-acute stroke. The phase angle was measured using a multifrequency bioimpedance analysis. Sarcopenic obesity was diagnosed according to the European Society of Clinical Nutrition and Metabolism/European Association for the Study of Obesity criteria. A multiple linear regression analysis was used to examine the association between the phase angle and sarcopenic obesity after adjusting for confounding factors. A receiver operating characteristic curve was used to calculate the optimal phase angle cutoff value for predicting sarcopenic obesity. RESULTS A total of 760 patients (median age 71 years; 352 women) were analyzed. The median (interquartile range, 25th and 75th percentiles) phase angle was 4.45° (4.10°, 4.88°). Sarcopenic obesity was diagnosed in 16 (3.9%) men, 18 (5.1%) women, and 34 (4.5%) patients overall. The multiple linear regression analysis showed that sarcopenic obesity (β = -0.185, p = 0.017) and sarcopenia (β = -0.121, p = 0.012) were significantly and negatively associated with the phase angle. Obesity was not significantly associated with the phase angle (β = -0.078, p = 0.094). The optimal cutoff value of the phase angle for diagnosing sarcopenic obesity was 4.29° (sensitivity 0.65, specificity 0.80, area under the curve [AUC] 0.79, 95% CI 0.77-0.87, p < 0.001) in men and 3.84° (sensitivity 0.67, specificity 0.84, AUC 0.81, 95% CI 0.79-0.86, p < 0.001) in women. CONCLUSION The phase angle was associated with sarcopenic obesity, and the cutoff values of the phase angle that could predict sarcopenic obesity were 4.29° for men and 3.84° for women. This simple and practical phase angle-based prediction of sarcopenic obesity can be useful in clinical practice.

Abstract
Stroke is one of the most common causes of disability in adults. Sarcopenia is a syndrome characterized by progressive systemic muscle loss and functional decline. The decrease in skeletal muscle mass and muscle function throughout the body after stroke cannot be explained by neurological motor disorders due to brain injury alone, it is considered to be a secondary sarcopenia known as stroke-related sarcopenia. Mounting evidences showed that stroke-related sarcopenia might promote the occurrence and development of sarcopenia through various pathogenesis such as muscle atrophy, dysphagia, inflammation, and malnutrition, etc. At present, the main indicators used to assess malnutrition in patients with stroke-related sarcopenia include temporalis muscle thickness, calf circumference, phase angle, geriatric nutritional risk index and mini-nutritional assessment short-form, etc. Currently, there is no particularly effective method to curb its progression, but supplementation with essential amino acids, whey protein combined with vitamin D, high energy diet, avoiding Polypharmacy, as well as increasing physical activity level and reducing sedentary lifestyle may improve the malnutrition status of stroke patients, and increase the muscle mass and skeletal muscle index, further delay or even prevent the development of stroke-related sarcopenia. This article reviews the latest research progress on the characteristics, epidemiology, pathogenesis and the role of nutrition in stroke-related sarcopenia, so as to provide reference for the clinical treatment and rehabilitation of stroke-related sarcopenia.

Abstract
OBJECTIVE This study examined the association between sarcopenia diagnosed by defining muscle mass with calf circumference and physical function at hospital discharge in patients with acute stroke and to perform a comparison with sarcopenia diagnosis according to the Asian Working Group for Sarcopenia. RESEARCH METHODS & PROCEDURES This retrospective cohort study included patients with acute stroke. We calculated the calf circumference cut-off value defining low skeletal muscle index for the Asian Working Group for Sarcopenia diagnostic criteria and used a combination of low calf circumference and low grip strength to define sarcopenia-calf circumference. A combination of low skeletal muscle index and low grip strength defined sarcopenia-Asian Working Group for Sarcopenia. Associations between sarcopenia-calf circumference, sarcopenia-Asian Working Group for Sarcopenia, and Functional Independence Measure motor score were evaluated using multiple regression analysis. RESULTS The study included 308 patients (198 men; mean age, 73.2 years). Sarcopenia-calf circumference prevalence was 24.7% in men and 46.4% in women. In men, sarcopenia-calf circumference (β=-0.178; 95% CI: -0.284, -0.073; p=0.001) and sarcopenia-Asian Working Group for Sarcopenia (β=-0.228; 95% CI: -0.330, -0.127; p<0.001) were significantly associated with Functional Independence Measure motor score at discharge. CONCLUSIONS Sarcopenia diagnosed by defining muscle mass with calf circumference was negatively associated with physical function at discharge in male patients with acute stroke. Sarcopenia diagnosed using Asian Working Group for Sarcopenia criteria was superior to sarcopenia-calf circumference for predicting physical function at discharge. Our findings suggest that the use of CC enables assessment of sarcopenia even at facilities where muscle mass measurements may be difficult.

Effects of muscle mass and muscle quality estimated by phase angle on functional outcomes in older patients undergoing rehabilitation: A prospective cohort study. Nutr Clin Pract 2023; 38:148-156. [PMID: 36309471 DOI: 10.1002/ncp.10920] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 08/24/2022] [Accepted: 09/24/2022] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Both skeletal muscle mass and muscle quality are important predictors of poor prognosis in older patients. However, the effects of muscle mass and muscle quality estimated by the phase angle (PhA) on functional outcomes in older patients undergoing rehabilitation have yet to be reported. This study aimed to investigate whether appendicular skeletal muscle index (SMI) and muscle quality estimated by PhA were independently associated with activities of daily living (ADL) and physical function in older patients undergoing rehabilitation. METHODS This prospective cohort study included older patients in a subacute rehabilitation hospital (n = 443). Baseline SMI and PhA were measured using bioelectrical impedance analysis, and low SMI or low PhA were determined using each cutoff value. The primary outcomes were ADL abilities measured using the functional independence measure for motor function (FIM-M) score and physical function measured using the short physical performance battery (SPPB) score at hospital discharge. Association between low SMI and low PhA and FIM-M or SPPB scores at discharge were determined using multiple regression analysis adjusted for confounding factors. RESULTS There were significant differences between the normal- and low-PhA groups in the FIM-M and SPPB scores at discharge (P < 0.001). In multiple regression analysis, low PhA was independently associated with FIM-M (β = -0.109, P = 0.013) and SPPB scores (β = 0.535, P < 0.001) at discharge; however, low SMI was not independently associated with these functional outcomes. CONCLUSION Decreased muscle quality estimated by the PhA was independently associated with poor ADL abilities and poor physical function in older patients undergoing rehabilitation.

Abstract
Malnutrition is common in stroke patients, as it is associated with neurological and cognitive impairment as well as clinical outcomes. Nutritional screening is a process with which to categorize the risk of malnutrition (i.e., nutritional risk) based on validated tools/procedures, which need to be rapid, simple, cost-effective, and reliable in the clinical setting. This review focuses on the tools/procedures used in stroke patients to assess nutritional risk, with a particular focus on their relationships with patients' clinical characteristics and outcomes. Different screening tools/procedures have been used in stroke patients, which have shown varying prevalence in terms of nutritional risk (higher in rehabilitation units) and significant relationships with clinical outcomes in the short- and long term, such as infection, disability, and mortality. Indeed, there have been few attempts to compare the usefulness and reliability of the different tools/procedures. More evidence is needed to identify appropriate approaches to assessing nutritional risk among stroke patients in the acute and sub-acute phase of disease or during rehabilitation; to evaluate the impact of nutritional treatment on the risk of malnutrition during hospital stay or rehabilitation unit; and to include nutritional screening in well-defined nutritional care protocols.

Abstract
Interventions for stroke-related sarcopenia in patients with stroke are needed, but the details of the target population are unclear. This systematic review aimed to identify trajectories of the prevalence of sarcopenia in the pre- and post-stroke periods and to determine the diagnostic criteria used in patients with stroke. We searched for literature in six databases: MEDLINE, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, and Ichushi-web (in Japanese). We included 1627 studies in the primary screening, and 35 studies were finally included. Of the 35 studies, 32 (91.4%) included Asian patients, and the criteria of the Asian Working Group for Sarcopenia was mainly used as the diagnostic criteria. Nineteen studies used muscle strength and muscle mass to diagnose sarcopenia, whereas a full assessment, including physical performance, was performed in five studies. The estimated prevalences of sarcopenia in pre-stroke, within 10 days of stroke, and from 10 days to 1 month after stroke were 15.8%, 29.5%, and 51.6%, respectively. Sarcopenia increased by approximately 15% from pre-stroke to 10 days, and increased by approximately 20% from 10 days to 1 month. Healthcare providers should note that the prevalence of sarcopenia increases during the acute phase in patients with stroke.

Abstract
Sarcopenia is commonly defined as the age-related loss of muscle mass and function and may be caused by several factors, such as genetics, environmental conditions, lifestyle, drug use, and, in particular, comorbidities. People with pre-existing conditions are more likely to develop sarcopenia and subsequently have a less favorable prognosis. Recently, phase angle (PhA), which is derived from bioelectrical impedance analysis (BIA), has received a great deal of attention, and numerous studies have been carried out to examine the relationship between PhA and sarcopenia in different conditions. Based on these studies, we expect that PhA could be used as a potential marker for sarcopenia in the future.

Abstract
Contemporary data on catheter-directed thrombolysis (CDT) utilization trends and associated hospital outcomes in pulmonary embolism (PE) n the US is limited. Using the nationwide inpatient sample database, we identified patients hospitalized for acute PE treated with CDT from January 1, 2008, to December 31, 2018. Cochrane-Armitage test was used to evaluate the temporal trends in utilization, hospital mortality, and major bleeding rates. Multivariate logistic regression was used to compare differences in the outcomes across race/ethnicity, 4444 patients (unweighted hospitalizations) underwent CDT during the study period. The mean age ± standard deviation of the population was 58 ± 16 years and the majority were males (54%). 3269 (73.6%) patients were non-Hispanic White (NHW), 802 (18.0%) patients were non-Hispanic Black (NHB), and 373 (8.4%) patients were of 'other' races/ethnicities. There was a more than tenfold increase in CDT use in 2018 compared to 2008. The total mortality and bleeding rates were approximately 7 and 10% respectively. Hospital mortality rates trended down across all races/ethnicities during the study period. A similar downward trend in bleeding rates was noted in NHB only (28.6% vs 10.7%, p = 0.04). In-hospital mortality and major bleeding odds were comparable across all races/ethnicities were comparable. NHB patients and other races were more likely to require blood transfusion and incur higher hospitalization costs compared with NHW patients. CDT use increased significantly in the US during the study period with a corresponding downward trend in in-hospital mortality across all races, and bleeding rates in NHB.

Abstract
OBJECTIVES To investigate the effect of trunk and appendicular skeletal muscle mass on the swallowing function at discharge in acute stroke patients. MATERIALS AND METHODS This retrospective cohort study included patients hospitalized after acute strokes. Skeletal muscle mass was measured by bioelectrical impedance analysis within 5 days of admission. The primary outcome was swallowing function at acute hospital discharge, assessed using the Functional Oral Intake Scale (FOIS). Secondary outcomes were Functional Independence Measure-eating (FIM-eating) scores and length of hospital stay. RESULTS Data from 231 patients (age 72.2 years; 151 men) were included in the analysis. The median trunk muscle mass index (TMI) was 8.2 and 6.8 kg/m2 in men and women, respectively. The median appendicular skeletal muscle mass index (ASMI) was 7.7 and 5.7 kg/m2 in men and women, respectively. The high TMI group had higher FIM-eating scores at discharge in each sex (p < 0.001). The high ASMI group had higher FOIS (p = 0.039 and 0.048) and FIM-eating scores at discharge (p = 0.046 and 0.047) in men and women, respectively. On multivariate analysis, TMI was independently associated with FIM-eating scores (β = 0.330, p < 0.001); ASMI was independently associated with FOIS (β = 0.229, p = 0.039) and FIM-eating scores (β = 0.111, p = 0.032). CONCLUSIONS Skeletal muscle mass had site-specific impacts on swallowing function and eating activities. This finding may contribute to the design of more individualized rehabilitation programs.

Abstract
[Purpose] We aimed to clarify the characteristics of age-related changes based on the
body composition data of old and super-old nursing home residents. [Participants and
Methods] This cross-sectional study included 53 female nursing home residents aged
75 years and above (mean age: 89.4 years; standard deviation: 5.6 years). They were
divided into the old and super-old groups. The old group consisted of 24 participants aged
between 75 and 89 years (mean age: 84.4 years; standard deviation: 3.7 years). The
super-old group consisted of 29 participants aged 90 years and above (mean age:
93.5 years; standard deviation: 2.7 years). The parameters such as phase angle, skeletal
muscle mass index, skeletal muscle mass, body fat percentage, body mass index, and Barthel
index were examined in the two groups. The relationship between age and phase angle was
determined, and the partial correlation coefficient was analyzed using the items for which
a significant difference was found between the two groups as adjustment variables.
[Results] The overall phase angle was 3.2 degrees, and that of the super-old group alone
was 2.6 degrees. Age-related difference was observed in the phase angle and Barthel index.
A significant correlation of −0.53 was observed between age and phase angle. The Barthel
index-adjusted partial correlation coefficient between age and phase angle was −0.35.
[Conclusion] The results of this study indicated that phase angle is an indicator of
physical condition associated with aging in female nursing home residents aged 75 to
100 years.

Abstract
OBJECTIVES To investigate the predictive value of the BIA-derived phase angle with respect to the functional prognosis and baseline sarcopenia in patients undergoing post-stroke rehabilitation. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS Overall, 577 Japanese patients admitted to a post-acute care hospital from 2016 to 2020 were recruited. MEASUREMENTS Body composition analysis, which included BIA-derived phase angle and skeletal muscle mass, was performed using bioelectrical impedance analysis (BIA). Study outcomes included physical function assessed using the Functional Independence Measure (FIM-motor) and the level of dysphagia assessed using the Food Intake LEVEL Scale (FILS). Sarcopenia was defined as the loss of skeletal muscle mass and decreased muscle strength. Receiver operating characteristic curves were used to calculate the optimal cutoff value of BIA-derived phase angle to diagnose sarcopenia. Multivariate analyses were used to determine whether the BIA-derived phase angle at admission was associated with outcomes at discharge and baseline sarcopenia. RESULTS After enrollment, 499 patients (mean age: 74.0 ± 13.1 years; 52.0% men) were examined. The median FIM-motor and FILS scores at admission were 47 (20-69) and 8 (7-10), respectively. Sarcopenia was observed in 43.2% of patients. After adjusting for potential confounders, BIA-derived phase angle was positively associated with FIM-motor scores at discharge (β = 0.134, P < 0.001), FIM-motor score gain (β = 2.504, P < 0.001), and FILS scores at discharge (β = 0.120, P = 0.039). BIA-derived phase angle was negatively associated with the sarcopenia diagnosis at baseline (odds ratio = -0.409, P < 0.001); its cutoff value was 4.76° (sensitivity 0.800, specificity 0.790, P < 0.001) for sarcopenia diagnosis in men and 4.11° (sensitivity 0.735, specificity 0.829, P < 0.001) in women. CONCLUSION BIA-derived phase angle was positively associated with the recovery of physical function and dysphagia level and negatively associated with baseline sarcopenia in patients undergoing post-stroke rehabilitation. The BIA-derived phase angle cutoff for sarcopenia diagnosis was 4.76° for men and 4.11° for women.
