Evidence on polypharmacy in patients with sarcopenia is lacking. We aimed to examine the association of polypharmacy with swallowing function and nutritional risk in post-stroke patient with sarcopenia. This retrospective cohort study included hospitalized patients diagnosed with sarcopenia who needed convalescent rehabilitation following stroke onset. Study outcomes were the Food Intake Level Scale (FILS) as dysphagia assessment and geriatric nutritional risk index (GNRI) as nutritional status at hospital discharge, respectively. To examine the impact of admission polypharmacy, multivariate linear regression analyses were used to determine whether the number of drugs prescribed at hospital admission was associated with these outcomes. As a result, of the 586 patients enrolled, 257 (mean age 79.3 years, 44.0% male) were diagnosed with sarcopenia and were finally analyzed high admission drug prescription numbers were independently associated with FILS (β = −0.133, p = 0.017) and GNRI (β = −0.145, p = 0.003) at hospital discharge, respectively. Polypharmacy is associated with dysphagia and malnutrition in post-stroke patients with sarcopenia. In addition to the combination of nutritional and exercise therapies, review and optimization of prescription medications may be warranted to treat sarcopenia in order to maximize improvement in outcomes for these patients.

Evidence is scarce for potentially inappropriate medications (PIMs) in rehabilitation medicine.To examine the effect of PIMs on functional recovery in older patients with sarcopenia after stroke.We conducted a retrospective cohort study in a post-acute rehabilitation hospital. All patients diagnosed with sarcopenia aged ≥ 65 years among all post-stroke patients hospitalized from 2015 to 2020 were included. PIMs were defined based on the 2019 Beers criteria. Sarcopenia was diagnosed using handgrip strength (HG) and skeletal muscle mass index (SMI), according to the criteria of the Asian Working Group for Sarcopenia 2019. The outcomes included functional independence measure motor (FIM-motor), HG, and SMI values at discharge. Multiple linear regression analyses were used to determine whether PIMs used at admission were independently associated with outcomes.Of the eligible patients, 361 were 65 years or older, of whom 196 (mean age 81.0 years, 44.4% male) presented with sarcopenia and were included in the analysis. Of these, 131 (66.8%) were prescribed PIMs at admission. The most frequently prescribed PIMs were proton pump inhibitors, antipsychotics, benzodiazepines, and nonsteroidal anti-inflammatory drugs. The number of PIMs on admission was independently associated with FIM-motor (β = - 0.132, P = 0.001) and HG (β = - 0.091, P = 0.048) at discharge, but not with SMI (β = - 0.055, P = 0.256).High admission PIMs prescription numbers are negatively associated with favorable discharge functional status and muscle strength in older patients with sarcopenia after stroke.

Currently, there is a lack of evidence to show that exercise therapy improves sarcopenia in older patients in clinical practice. We therefore conducted a retrospective cohort study to clarify the effects of chair-stand exercise on improving sarcopenia among patients diagnosed with sarcopenia undergoing convalescent rehabilitation after stroke. According to the latest Asian criteria, sarcopenia was diagnosed when both skeletal muscle mass index (SMI) and handgrip strength (HGS) were low. Patients were asked to perform a repeated chair-stand exercise as whole-body resistance training, in addition to the rehabilitation program. Outcomes included sarcopenia rates, SMI, HGS, and physical function at hospital discharge. Multivariate analyses were used to examine whether the frequency of daily chair-stand exercise was independently associated with the outcomes after adjustment for potential confounders. After enrollment, 302 patients with sarcopenia (mean age: 78.6 years; 46.4% male) were analyzed. Overall, sarcopenia prevalence decreased by 21.9%, from 100% at admission to 78.1% at discharge. Multivariate analyses showed that the frequency of the exercise was significantly associated with the presence of sarcopenia (odds ratio: 0.986, p = 0.010), SMI (β = 0.181, p < 0.001), and HGS (β = 0.101, p = 0.032) at discharge, respectively. The chair-standing exercise was effective in improving sarcopenia in these patients.

BackgroundEvidence is scarce regarding the polypharmacy and potentially inappropriate medications (PIMs) in rehabilitation medicine.AimTo investigate the prevalence and impact on outcomes of polypharmacy and PIMs in stroke rehabilitation.MethodsA retrospective cohort study was conducted with 849 older inpatients after stroke.Polypharmacy was defined as six or more medications, and PIMs were defined based on Beers criteria 2019. Study outcomes included Functional Independence Measure (FIM)-motor, FIM-cognitive, energy intake, dysphagia, length of hospital stay and the rate of home discharge. To consider the impact of pharmacotherapy during rehabilitation, multivariate analyses were used to determine whether the presence of polypharmacy or PIMs at discharge was associated with outcomes.ResultsAfter enrollment, 361 patients (mean age 78.3 ± 7.7 years; 49.3% male) were analyzed. Polypharmacy was observed in 43.8% and 62.9% of patients, and any PIMs were observed 64.8% and 65.4% of patients at admission and discharge, respectively. The most frequently prescribed PIMs included antipsychotics, benzodiazepines, and proton pump inhibitors. Polypharmacy was negatively associated with FIM-motor score (β = -0.072, P = 0.017), FIM-cognitive score (β = -0.077, P = 0.011), energy intake (β = -0.147, P = 0.004), and home discharge (OR: 0.499; 95% CI: 0.280, 0.802; P = 0.015). PIMs were negatively associated with energy intake (β = -0.066, P = 0.042) and home discharge (OR: 0.452; 95% CI: 0.215, 0.756; P = 0.005).ConclusionsPolypharmacy and PIMs are commonly found among older patients undergoing stroke rehabilitation. Moreover, polypharmacy and PIMs are negatively associated with outcomes.

PIMs were negatively associated with home discharge (OR: 0.375; 95% CI: 0.195, 0.718; P = 0.003). Conclusion Polypharmacy and PIMs are commonly found among older patients undergoing stroke rehabilitation. Moreover, polypharmacy was negatively associated with activities of daily living (ADL) but not with PIMs and ADLs, and both were associated with home discharge.

We conducted a retrospective observational study in 170 older, underweight patients after stroke to elucidate whether stored energy was associated with gains in body weight (BW) and skeletal muscle mass (SMM). Energy intake was recorded on admission. The energy requirement was estimated as actual BW (kg) × 30 (kcal/day), and the stored energy was defined as the energy intake minus the energy requirement. Body composition was measured by bioelectrical impedance analysis. The study participants gained an average of 1.0 ± 2.6 kg of BW over a mean hospital stay of 100 ± 42 days with a mean stored energy of 96.2 ± 91.4 kcal per day. They also gained an average of 0.2 ± 1.6 kg of SMM and 0.5 ± 2.3 kg of fat mass (FM). This means about 9600 kcal were needed to gain 1 kg of BW. In addition, a 1 kg increase in body weight resulted in a 23.7% increase in SMM and a 45.8% increase in FM. Multivariate regression analyses showed that the stored energy was significantly associated with gains in BW and SMM. Aggressive nutrition therapy is important for improving nutritional status and function in patients with malnutrition and sarcopenia.

The aim of this study was to evaluate the effect of sarcopenia on functional outcomes, including activities of daily living (ADLs); dysphagia status; and the rate of home discharge, among hospitalized adults receiving convalescent rehabilitation.A retrospective cohort study was conducted with 898 patients newly admitted to in-hospital convalescent rehabilitation wards at a single rehabilitation hospital in Japan. Baseline sarcopenia was diagnosed using muscle mass index and handgrip strength according to the criteria of the European Working Group on Sarcopenia in Older People, with the cutoff values of the Asian Working Group for Sarcopenia. The primary outcome was ADLs, assessed by Functional Independence Measure motor (FIM-motor) score at hospital discharge. The secondary outcomes included dysphagia, assessed by the Food Intake Level Scale (FILS), at discharge, and the rate of home discharge. Three multivariate analyses revealed an association between sarcopenia and the clinical outcomes. Each analysis adjusted for the following confounders: age, sex, time from onset, premorbid ADLs, comorbidities, cognitive level, nutritional status, major drugs, and admission diagnoses.After enrollment, 795 patients (mean age 74.9 ± 13.2 y; 59% women) were included in the final analysis. Admission diagnoses included stroke (n = 276; 34.7%), musculoskeletal disorders (n = 382; 48.1%), and hospital-associated deconditioning (n = 137; 17.2%). Of the 795 patients examined, 402 (50.6%) had sarcopenia. The multiple linear regression analysis showed that sarcopenia was independently associated with FIM motor score at discharge in patients with all disease types (β = -0.189 [stroke], -0.240 [musculoskeletal disorders], -0.230 [hospital-associated deconditioning]; all P0.05), with FILS score at discharge only in patients with musculoskeletal disorders (β = -0.271, P0.001), but not in patients with stroke (β = -0.061, P = 0.375) or those with hospital-associated deconditioning (β = -0.131, P = 0.070). The multiple logistic regression analysis showed that sarcopenia was associated with rate of home discharge in all disease types (odds ratio [OR], 0.201; 95% confidence interval [CI], 0.067-0.597 for stroke; OR, 0.242; 95% CI, 0.076-0.772 for musculoskeletal disorders; OR, 0.121; 95% CI, 0.110-0.347 for hospital-associated deconditioning; all P0.05).Sarcopenia is associated with worse recovery of ADLs and dysphagia and a lower rate of home discharge in hospitalized adults undergoing convalescent rehabilitation. Early detection of sarcopenia and treatment by rehabilitation nutrition should be implemented in this population.

Sarcopenic obesity is of growing research and clinical interest; however, validated diagnostic criteria are lacking. We therefore aimed to examine the prevalence of sarcopenic obesity as diagnosed by the criteria recently proposed by the European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO), and its association with outcomes among patients after stroke. This study was based on a cohort of 760 Japanese patients after stroke admitted to a post-acute rehabilitation hospital. Sarcopenic obesity was diagnosed at admission according to the ESPEN and EASO criteria using reference values specific to Asians. Outcomes included the motor domain of the functional independence measure (FIM-motor) and the food intake level scale (FILS) at discharge. Multivariate linear regression models were used to assess the associations between sarcopenic obesity and outcomes. Among 760 patients (median age, 73 years; 352 women and 408 men), sarcopenic obesity was diagnosed in 34 patients (4.5%; 5.4% of women and 4.1% of men). In multivariate analyses, sarcopenic obesity was independently and negatively associated with FIM-motor (β = −0.048, p = 0.031) and FILS at discharge (β = −0.095, p = 0.046) in women. In contrast, in men, sarcopenic obesity showed an independent negative association with FIM-motor at discharge (β = −0.117, p < 0.001) but no statistically significant association with FILS at discharge (β = −0.004, p = 0.323). In conclusion, the prevalence of sarcopenic obesity diagnosed by the ESPEN and EASO-defined criteria was as low as 4.5% among Japanese patients after stroke. Furthermore, sarcopenic obesity was negatively associated with improvements in activities of daily living and dysphagia.

Oral problems affect rehabilitation outcomes. This study aimed to examine the association between improvement in oral health and functional outcomes in patients after stroke.This retrospective cohort study included post-acute rehabilitation patients who presented with oral problems at admission. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). The ROAG score change during hospitalization was calculated by subtracting the score at admission from the score at discharge; oral problems were defined as "improved", when the score change value was lower than the median value. Study outcomes were the activities of daily living assessed by the motor domain of the Functional Independence Measure (FIM-motor) scores and dysphagia as assessed by the Food Intake Level Scale (FILS). Multivariate regression analyses were used to determine whether improved oral problems were associated with study outcomes. P-values of0.05 were considered statistically significant.This study included 300 patients (mean age, 72.0 years; 51.7% men). The median [IQR] baseline ROAG score and its change value during hospitalization were 11 [10, 14] and -1[-3, 0] points, respectively. Multivariate analyses showed that improved oral problems was independently associated with FIM-motor score (β = 0.144, p = 0.001) and FILS score (β = 0.227, p0.001) at discharge, after adjusting for potential confounders.Improvement in oral health was positively associated with recovery of the ADL and dysphagia after stroke. Early detection of oral problems and oral treatment should be implemented in these patients to maximize functional recovery.

Evidence regarding the effect of sarcopenic obesity on recovery in stroke patients is scarce in rehabilitation medicine. The aim of this study was to examine the association between changes in muscle strength and functional outcomes in patients with sarcopenic obesity undergoing rehabilitation after stroke.This study was a retrospective cohort study of stroke patients, consecutively admitted to post-acute rehabilitation wards of a single hospital, of which, only those diagnosed with sarcopenic obesity at admission were included in the final analysis. Bioimpedance analysis was used to measure skeletal muscle mass and body fat mass. Sarcopenic obesity was defined as the presence of both sarcopenia and obesity. Sarcopenia was diagnosed using muscle mass index and handgrip strength. Obesity was diagnosed using body fat percentage (men ≥30%, women ≥35%). The evaluated outcomes were Functional Independence Measure (FIM)-motor score at discharge and its gain. Multiple regression analysis was used to verify whether changes in hand grip strength during hospitalization were associated with functional outcomes.Sixty-two patients (29 men) with a mean age of 78 years, were analyzed. The mean change in the hand grip strength was 3.9 kg. In multiple regression analysis, changes in the hand grip strength were significantly associated with FIM-motor at discharge (β = 0.34, P0.01) and FIM-motor gain (β = 0.58, P0.01).Muscle strength gain was associated with improved functional recovery in stroke patients with sarcopenic obesity.

Objectives The aim of this study was to evaluate the associations between hemoglobin improvement and functional outcomes in anemic patients after stroke. Methods This retrospective cohort study included consecutive hospitalized post-stroke patients with anemia. Data on serum hemoglobin level were extracted from medical records. The “change in hemoglobin levels” was defined as the pre-discharge hemoglobin level minus the baseline hemoglobin level. Study outcomes included the Functional Independence Measure-motor (FIM-motor) efficacy, and length of stay. Multivariate analyses were used to determine whether the change in hemoglobin levels was independently associated with study outcomes, after adjusting for potential confounders. Results Of the 637 patients admitted, 194 stroke patients (mean age 75.4 years; 53.6% women) presented anemia at baseline and were included in the analysis. The mean (SD) baseline hemoglobin level was 11.2 (0.9) g/dL and the median (IQR) change was 0.4 (0.1–1.1) g/dL. In multivariate analyses, the change in hemoglobin levels was positively associated with the FIM-motor efficacy (β = 0.114, p = 0.031), and negatively associated with length of stay (β = −0.059, p = 0.039). Moreover, the baseline hemoglobin level was independently associated with the FIM-motor efficacy (β = 0.267, p = 0.001). Conclusions A lower baseline hemoglobin level is negatively associated with functional recovery, and hemoglobin improvement is positively associated with functional recovery and shorter hospital stay in stroke patients with anemia. Anemia should be assessed at baseline as a prognostic indicator and, if treatable, treated appropriately to maximize outcomes in these patients.

AIM To elucidate the effects of whole-body exercise on clinical outcomes, including dysphagia status, between stroke patients with dysphagia who are undergoing convalescent rehabilitation. METHODS This retrospective cohort study included consecutive patients with post-stroke dysphagia in a rehabilitation hospital in Japan between 2016 and 2018. Dysphagia was defined as a Food Intake Level Scale (FILS) score

Objective Intervention for treating sarcopenia is of great concern in clinical settings. The aim of this study was to investigate the relationship between changes in skeletal muscle mass and functional outcomes in patients with sarcopenia after stroke. Methods A retrospective cohort study of stroke patients with sarcopenia consecutively admitted to a single center's convalescent rehabilitation wards was conducted from 2015 to 2018. Sarcopenia was defined as a loss of skeletal muscle mass index (SMI) with bioelectrical impedance and decreased muscle strength as measured by handgrip strength; cut-off values were adopted from the 2019 Asian Working Group for Sarcopenia. Changes in SMI during hospitalization were measured. Outcomes included the motor domain of Functional Independence Measure at discharge and its gain. Multivariate analysis determined whether the changes in SMI were associated with these outcomes. Results During the study period, 272 stroke patients were enrolled. Of those, 120 patients (44%) (mean age 79 years, 70 females) were diagnosed with sarcopenia. The mean (SD) for changes in SMI was 0.2 (0.5) kg/m2. Multiple linear regression analysis showed that changes in SMI were significantly associated with Functional Independence Measure – motor at discharge (β=0.175, P=0.003) and Functional Independence Measure – motor gain (β=0.247, P=0.003). Conclusions Muscle mass gain may be positively associated with functional recovery in patients with sarcopenia after stroke. Exercise and nutritional therapy to increase skeletal muscle mass, in addition to conventional stroke rehabilitation, is needed for these patients.

Summary Background The purpose of this study was to investigate the prevalence of sarcopenia following stroke, musculoskeletal disease, or hospital-associated deconditioning in convalescent rehabilitation ward inpatients. The association between the activities of daily living (ADLs), dysphagia, and sarcopenia was also assessed. Methods A cross-sectional study was performed in consecutive patients admitted to convalescent rehabilitation wards. Sarcopenia was defined as a loss of skeletal muscle mass and decreased muscle strength. The primary outcome was the Functional Independence Measure (FIM) score. Body mass index, Mini Nutritional Assessment-Short Form score, Food Intake Level Scale (FILS) score, Charlson Comorbidity Index, premorbid modified Rankin scale, time from onset, reason for admission, bioelectrical impedance analysis for skeletal muscle mass and fat mass, and handgrip strength were also assessed. Univariate and multivariate analyses were used to determine whether ADLs and dysphagia were associated with sarcopenia. Results The study included 637 patients (mean age: 74 years; 271 men and 366 women). Sarcopenia was diagnosed in 343 (53.0%) patients (141 men and 202 women). Sarcopenia was identified in 53.6% (125/233) of stroke patients (59.8%, 50.0%, and 34.6% of patients with brain infarctions, brain hemorrhages, and subarachnoid hemorrhages, respectively). Sarcopenia was found in 51.3% (154/300) of patients with musculoskeletal diseases (59.5%, 53.6%, and 36.5% of patients with hip fractures, vertebral compression fractures, and total knee arthroplasty, respectively). Of patients with hospital-associated deconditioning, 61.5% (64/104) had sarcopenia (95.1% and 39.7% of patients with pneumonia and other acute diseases, respectively). Multivariate analysis showed that FIM motor domain and FILS scores were independently associated with skeletal muscle mass loss and decreased muscle strength. Conclusions The prevalence of sarcopenia in convalescent rehabilitation ward inpatients was 53.0%. ADLs and dysphagia were independently associated with sarcopenia in this study population. Sarcopenia with disabilities should be assessed for all patients in rehabilitation settings.

Evidence is scarce regarding the polypharmacy in patients with sarcopenia. The aim of this study was to investigate the effect of deprescribing for polypharmacy on the improvement of nutritional intake and sarcopenia in older patients with sarcopenia. A retrospective cohort study was conducted with hospitalized older patients with sarcopenia undergoing rehabilitation after stroke. Study outcomes included energy intake, protein intake, handgrip strength (HG) and skeletal muscle mass index (SMI) at hospital discharge. To consider the effects of deprescribing for polypharmacy, we used multivariate analyses to examine whether the change in the number of medications during hospitalization was associated with outcomes. Of 361 patients after enrollment, 91 (mean age 81.0 years, 48.4% male) presented with sarcopenia and polypharmacy and were eligible for analysis. The change in the number of medications was independently associated with energy intake (β = −0.237, p = 0.009) and protein intake (β = −0.242, p = 0.047) at discharge, and was not statistically significantly associated with HG (β = −0.018, p = 0.768) and SMI (β = 0.083, p = 0.265) at discharge, respectively. Deprescribing was associated with improved nutritional intake in older sarcopenic patients with polypharmacy undergoing stroke rehabilitation.

The aim of this study was to examine the association between sarcopenia and recovery of independence in urination and defecation in patients undergoing convalescent rehabilitation.This single-center, retrospective cohort study included post-acute rehabilitation patients. Sarcopenia was diagnosed using the muscle mass index and handgrip strength according to the updated criteria of the Asian Working Group for Sarcopenia 2019. Study outcomes and the recovery of independence in urination and defecation were evaluated using the sphincter control items of the Functional Independence Measure (FIM) at discharge: urination (FIM-Bladder) and defecation (FIM-Bowel), respectively. Multivariate regression analyses were used to determine whether sarcopenia at baseline was associated with the study outcomes. Statistical significance was set at P0.05.After enrollment, 917 patients (mean age 74.7 ± 13.5 y; 58% women) were included in the final analyses. Sarcopenia was present in 451 patients (49.2%). The median FIM-Bladder and FIM-Bowel scores at admission were 5 [2-7] and 5 [3-7], respectively. Multivariate analyses showed that the presence of sarcopenia at admission was independently and negatively associated with FIM-Bladder and FIM-Bowel at discharge (all P0.001), respectively, after adjusting for potential confounders including baseline outcome variables, FIM, and disease.Sarcopenia was negatively associated with the recovery of independence in urination and defecation in a post-acute rehabilitation setting. This relationship was independent of physical and cognitive level and disease. Early detection of sarcopenia and treatment by rehabilitation nutrition should be implemented to predict and maximize improvement in toileting independence in this population.

Objective The aim of this study was to evaluate the effect of sarcopenic obesity on activities of daily living and home discharge rates in adults undergoing convalescent rehabilitation. In addition, we evaluated diagnostic criteria for sarcopenic obesity to predict outcomes. Design A retrospective cohort study. Setting and Participants In total, 971 Japanese patients in a post-acute rehabilitation hospital between 2014 and 2016. Methods Sarcopenic obesity was defined as the presence of both sarcopenia and obesity. Sarcopenia was diagnosed using muscle mass index and handgrip strength according to the criteria of the European Working Group on Sarcopenia in Older People, with the cut-off values of the Asian Working Group for Sarcopenia. Obesity was diagnosed exploratively using several definitions: percentage of body fat (FAT%), body mass index (>25 kg/m2), and fat mass index (4th quartile). Study outcomes included Functional Independence Measure-motor efficacy (score gain between admission and discharge divided by the length of stay) and the rate of home discharge. Multivariate analyses were used to determine whether sarcopenic obesity was associated with outcomes and which obesity definition was suitable for outcome prediction. P values of Results After enrollment, 917 patients (mean age 74.7 ± 13.5 years; 59% women) were included in the final analyses. The frequency of sarcopenic obesity varied greatly depending on the sex and method of obesity diagnosis: 2.1% when body mass index >25 kg/m2 was used for obesity diagnosis in men, and 40.7% when FAT% >25% was used in women. Further, FAT% >35% and FAT% >30% used in women and men, respectively, had the strongest association with Functional Independence Measure-motor efficacy. FAT% of >30% and >35% in women and >30 in men was associated with the rate of home discharge. Conclusions and Implications Sarcopenic obesity was negatively associated with functional improvement and home discharge in post-acute rehabilitation. Clinical thresholds for diagnosing sarcopenic obesity should include FAT% >35 and >30% in women and men, respectively, in defining obesity in this population.

Evidence for appropriate nutritional assessment, energy prediction, and adaptation and their effect on outcomes after stroke is scarce. We sought to determine the frequency of individualized dietary prescriptions issued for individuals undergoing rehabilitation after stroke and to analyze the effect of diet-prescription frequency on outcomes after stroke.This single-center prospective cohort study included poststroke patients newly admitted to convalescent rehabilitation wards. The frequency and content of dietary prescriptions issued as part of nutritional assessments were examined. Study outcomes were nutritional status assessed using changes in skeletal muscle mass, physical function assessed using the Functional Independence Measure motor score, dysphagia status assessed using the Food Intake LEVEL Scale (score7), and length of hospital stay. Multivariate analyses were performed to determine whether the frequency of dietary prescriptions issued during hospitalization was independently associated with outcomes of interest, after adjusting for potential confounders.A total of 454 participants (mean age = 71.8 y; 53.1% men, 46.9% women) were included in the final analysis data set. A median of five (range, 2-11) dietary prescriptions were issued per participant during the median 96 d of hospitalization, with the most common items being diet-texture modification for dysphagia and oral energy/protein enhancement. In multivariate analyses, the frequency of dietary prescriptions was independently associated with the change in skeletal muscle mass (β = 0.165, P = 0.028), Functional Independence Measure motor scores at discharge (β = 0.104, P = 0.045), length of stay (β = -0.056, P = 0.019), and presence of dysphagia at discharge (odds ratio = 0.949, P = 0.032).Frequent and individualized nutritional support is associated with improved nutritional status, physical function, and dysphagia after stroke. Intensive nutritional support through multidisciplinary discussion plays a central role in the prevention and management of malnutrition to maximize the improvement of patient outcomes. This study is the first to report this association.

Objectives To evaluate the associations between estimated glomerular filtration rate (eGFR) and sarcopenia and functional outcomes after stroke. Methods This retrospective cohort study included hospitalized patients after stroke. Data on serum creatinine-based eGFR were extracted from medical records. Primary outcome was the presence of sarcopenia at admission, diagnosed based on both low skeletal muscle mass and strength criteria as per the AWGS 2019. Other outcomes included the Food Intake Level Scale (FILS) score (measure of dysphagia, FILS score Results Data from 813 patients (mean age 73.5 years; 51.9% men) were included in the analysis. The median eGFR was 65.1 ml/min/1.73 m2, and about 41% of patients had an eGFR less than 60 ml/min/1.73 m2 at the baseline. Sarcopenia was observed in 47.4% of patients. In the multivariate analyses, baseline eGFR was positively associated with sarcopenia at admission (odds ratio [OR]=1.016, 95% confidence interval [CI]: 1.005–1.027, p = 0.003), the presence of dysphagia at discharge (OR=1.016, 95% CI: 1.001–1.031, p = 0.045), and negatively associated with FIM-motor score at discharge (β= -0.046, p = 0.047) and its gain (β= -0.067, p = 0.037). Conclusions Elevated creatinine-based eGFR is associated with sarcopenia, dysphagia, and adverse rehabilitation outcomes after stroke. Our findings highlight the limitations of assessing renal function using creatinine levels in patients with sarcopenia: therefore, future studies using cystatin C are needed to validate our findings.

Objective The aim of our study was to investigate how systemic inflammation relates to sarcopenia and its impact on functional outcomes in the recovery stages of stroke. Methods A retrospective cohort study was performed in consecutive patients admitted to convalescent rehabilitation wards following stroke. Patients with acute or chronic high-grade inflammatory diseases were excluded. Systemic inflammation was evaluated using the modified Glasgow Prognostic Score (mGPS). Sarcopenia was defined as a loss of skeletal muscle mass and decreased muscle strength, with the cut-off values set by the Asian Working Group for Sarcopenia. The primary outcome was the motor domain of the Functional Independence Measure (FIM-motor). Univariate and multivariate analyses were used to determine whether mGPS was associated with sarcopenia and FIM-motor at discharge. Results The study included 204 patients (mean age 74.1 years, 109 men). mGPS scores of 0, 1, and 2 were assigned to 149 (73.0%), 40 (19.6%), and 13 (6.4%) patients, respectively. Sarcopenia was diagnosed in 81 (39.7%) patients and was independently associated with stroke history (odds ratio [OR] 1.890, P=0.027), premorbid modified Rankin scale (OR 1.520, P=0.040), body mass index (OR 0.858, P=0.022), and mGPS score (OR 1.380, P=0.021). Furthermore, the mGPS score was independently associated with sarcopenia (OR 1.380, P=0.021) and FIM-motor at discharge (β=-0.131, P=0.031). Conclusion Systemic inflammation is closely associated with sarcopenia and poor functional outcomes in the recovery stage of stroke. Early detection of systemic inflammation and sarcopenia can help promote both adequate exercise and nutritional support to restore muscle mass and improve post-stroke functional recovery.

The aim of this study was to investigate the effects of a leucine-enriched amino acid supplement on muscle mass, muscle strength, and physical function in post-stroke patients with sarcopenia.We conducted an eight-wk, two-parallel group intervention, randomized controlled, blinded outcome assessment among 44 post-stroke older patients with sarcopenia. Sarcopenia was defined as a loss of skeletal muscle mass and decreased muscle strength according to the Asian Working Group for Sarcopenia criteria. The intervention group (n = 21) received a leucine-enriched amino acid supplement; the control group (n = 23) did not. Both groups performed low-intensity resistance training in addition to a post-stroke rehabilitation program. A primary outcome of physical function by using the motor domain of Functional Independence Measure (FIM), and secondary outcomes of appendicular muscle mass (skeletal muscle mass index [SMI]) measured via bioelectrical impedance analysis and muscle strength as handgrip strength were measured at baseline and at the end of the intervention.The FIM score increased significantly in both groups over time (P0.01), with significantly greater improvement in the intervention group than in the control group (P0.045). Handgrip strength also increased significantly over time (P0.05), with significantly greater improvement in the intervention group (P0.01). The SMI increased significantly in the intervention group but not in the control group over time, with significantly greater improvement in the intervention group (median estimated difference, 0.50 kg/mWe demonstrated that an eight-wk intervention consisting of a leucine-enriched amino acid supplementation and low-intensity resistance training increased muscle mass, strength, and physical function in post-stroke patients with sarcopenia.
