Frequent and personalized nutritional support leads to improved nutritional status, activities of daily living, and dysphagia after stroke

Improvement of oral function and its impact on oral food intake in subacute stroke patients: A prospective study with dental intervention

BACKGROUND

The association between oral food intake and oral function during the subacute stage of stroke is not well known.

OBJECTIVE

To investigate (1) oral function changes in subacute stroke patients and (2) association between oral function and oral intake status at several time points.

METHODS

In a prospective study involving 324 stroke patients at a convalescent rehabilitation unit, four oral function parameters (maximum tongue pressure, MTP; lip-tongue motor function, LTMF; maximum occlusal force, MOF and oral health assessment tool, OHAT) were quantitatively measured upon admission (T0), at 1 month (T1) and 2 months (T2). Oral feeding status was assessed using the Functional Oral Intake Scale (FOIS) and divided based on the FOIS score into the dysphagic and regular diet groups. The changes in oral functions at the three time points were tested using generalized estimating equation analysis. The association between FOIS groups and oral functions at T1 and T2 was analysed by means of logistic regression analysis.

RESULTS

All oral function parameters improved significantly over time during the hospital stay (mean differences: 4.9 for MTP, 0.6 for LTMF, 1.1 for MOF and -1.8 for OHAT). The FOIS groups were significantly associated with MTP (p < .05) and OHAT (p < .05) at both T1 and T2.

CONCLUSION

Our findings suggest that oral function significantly improves in patients during subacute stroke rehabilitation and better oral health can be associated with better oral intake. Improved oral function through dental intervention and oral rehabilitation may contribute to gains in oral food intake.

The effect of the nutritional status and dietary inflammatory index on frailty and activities of daily living in geriatric outpatients

BACKGROUND

It has been reported that the inflammatory process plays a role in the pathophysiology of frailty in elderly individuals and that diet is effective in regulating chronic inflammation.

OBJECTIVE

This study aims to evaluate the effects of nutritional status and dietary inflammatory index on frailty and activities of daily living in the elderly.

METHOD

A cross-sectional study in a hospital in Turkey has been carried out with 187 over the age of 65 who presented to the geriatric outpatient clinic participants. Anthropometric measurements of the patients were recorded, and the dietary inflammatory index (DII) was calculated using the 24-h dietary recall method. Mini Nutritional Assessment (MNA) was used to determine the malnutrition risk, the FRAIL scale was used for frailty assessment, and Katz and Lawton & Brody scales were used for daily living activities.

RESULTS

The mean age of the elderly is 70.83 ± 4.98 years. The frailty rate was determined to be 28.3%. The DII score was determined as 4.41 ± 5.16 in frail patients and 1.62 ± 4.39 in non-frail patients (p < 0.05). While DII showed a negative correlation with the Lawton & Brody scale score (r =  - 0.353), MNA was positively correlated to the Katz score (r = 0.386, p = 0.000) and the Lawton & Brody score (r = 0.475). In addition, one-unit increase in the MNA score was associated with a 29% decrease in the risk of frailty.

CONCLUSIONS

The dietary inflammatory index was found to be high in frail and malnourished individuals. It was determined that the quality of life of individuals with malnutrition decreased.

Associations between Baseline Hyponatremia and Activities of Daily Living and Muscle Health in Convalescent Stroke Patients

Objectives

Evidence is scarce regarding the association between hyponatremia and functional outcomes among older hospitalized patients. We aimed to evaluate the associations between baseline hyponatremia and improvement in activities of daily living (ADL) and muscle health in hospitalized post-stroke patients.

Methods

This retrospective cohort study included hospitalized post-stroke patients. Serum sodium concentrations were extracted from medical records based on blood tests performed within 24 h of admission, with hyponatremia defined as a serum sodium concentration below135 mEq/L. Primary outcome was the discharge ADL as assessed by the motor domain of the Functional Independence Measure (FIM-motor) and its corresponding gain during hospitalization. Other outcomes encompassed the discharge scores for skeletal muscle mass (SMI) and handgrip strength (HGS). Multivariate linear regression analyses were used to determine the association between hyponatremia and outcomes of interest, adjusted for potential confounders.

Results

Data from 955 patients (mean age 73.2 years; 53.6% men) were analyzed. The median baseline blood sodium level was 139 [interquartile range: 137, 141] mEq/L, and 84 patients (8.8%) exhibited hyponatremia. After full adjustment for confounders, baseline hyponatremia was significantly and negatively associated with FIM-motor at discharge (β=-0.036, P=0.033) and its gain during hospital stay (β=-0.051, P=0.033). Baseline hyponatremia exhibited an independent and negative association with discharge HGS (β=-0.031, P=0.027), whereas no significant association was found between baseline hyponatremia and discharge SMI (β=-0.015, P=0.244).

Conclusions

Baseline hyponatremia demonstrated a correlation with compromised ADL and muscle health in individuals undergoing rehabilitation after stroke.

Combined systematic screening for malnutrition and dysphagia in hospitalized older adults: a scoping review

BACKGROUND

Dysphagia affects about 40% of patients admitted to acute geriatric wards, as it is closely associated with diseases that rise in prevalence with advancing age, such as stroke, Parkinson's disease, and dementia. Malnutrition is a highly associated predictive factor of dysphagia as well as one of the most common symptoms caused by dysphagia. Thus, the two conditions may exist simultaneously but also influence each other negatively and quickly cause functional decline especially in older adults. The purpose of this review was to determine whether institutions have established a protocol combining screenings for dysphagia and malnutrition on a global scale. If combined screening protocols have been implemented, the respective derived measures will be reported.

METHODS

A scoping review was conducted. A systematic database search was carried out in January and February 2024. Studies were included that examined adult hospitalized patients who were systematically screened for dysphagia and malnutrition. The results were managed through the review software tool Covidence. The screening of titles and abstracts was handled independently by two reviewers; conflicts were discussed and resolved by consensus between three authors. This procedure was retained for full-text analysis and extraction. The extraction template was piloted and revised following feedback prior to extraction, which was carried out in February 2024.

RESULTS

A total of 2014 studies were found, 1075 of which were included for abstract screening, 80 for full text screening. In the end, 27 studies were extracted and reported following the reporting guideline PRISMA with the extension for Scoping Reviews.

CONCLUSION

Most of the studies considered the prevalence and association of dysphagia and malnutrition with varying outcomes such as nutritional status, pneumonia, oral nutrition, and swallowing function. Only two studies had implemented multi-professional nutrition teams.

Impaired oral status is associated with sarcopenic obesity in post-stroke patients

PURPOSE

Oral problems and muscle health are indeed significant concerns in ageing populations. However, there is limited evidence concerning the association between these issues. The study's focus was to investigate the association between oral problems and sarcopenic obesity, wherein sarcopenia and obesity coexist concurrently, in post-stroke patients.

METHODS

This retrospective, observational, cross-sectional study included patients hospitalised for post-stroke rehabilitation. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). Sarcopenic obesity was diagnosed according to the European Society of Clinical Nutrition and Metabolism/European Association for the Study of Obesity criteria. Multiple linear regression analysis was used to examine the association between the ROAG and sarcopenic obesity after adjusting for confounding factors.

RESULTS

A total of 760 patients were included, with a mean (SD) age of 71 (9) years, of whom 408 (54.7%) were male. The median (interquartile range, 25th and 75th percentiles) ROAG was 11 [9, 13]. Sarcopenic obesity was diagnosed in 16 (3.9%) men, 18 (5.1%) women, and 34 (4.5%) patients overall. Multivariate linear analysis showed that ROAG was significantly and positively associated with sarcopenic obesity (β = .091, P = .023), followed by obesity alone (β = .084, P = .044), and sarcopenia alone (β = .081, P = .037).

CONCLUSION

Oral problems were associated with sarcopenic obesity in post-stroke. Oral assessment and intervention may have a positive impact on ADL and QOL in post-stroke patients with sarcopenic obesity.

Prevalence and influencing factors of malnutrition in stroke patients with bulbar paralysis: a cross-sectional study in China

Background

Although malnutrition has been shown to influence the clinical outcomes of Stroke Patients with Bulbar Paralysis (SPBP), the prevalence and influencing factors have yet to be uncovered.

Objective

This study aims to assess the current prevalence and factors associated with malnutrition in SPBP.

Methods

A multicenter cross-sectional investigation was conducted among SPBP in China from 2019 to 2021. Information was collected on basic information, health condition, diagnosis, treatment, neurological function, activities of daily living, swallowing function, and nutritional status. A multivariable logistic regression model was used to identify the factors that influenced nutritional status. ROC analysis was used to assess the predictive value of each independent influencing factor and the logit model.

Results

In total, 774 SPBP were enrolled, and the prevalence of malnutrition was 60.59%. Pulmonary infection [aOR:2.849, 95%CI: (1.426, 5.691)], hemoglobin [aOR: 0.932, 95%CI: (0.875, 0.982)], serum albumin [aOR: 0.904, 95%CI: (0.871, 0.938)], total protein [aOR: 0.891, 95%CI: (0.819, 0.969)], prealbumin [aOR: 0.962, 95%CI: (0.932, 0.993)], and National Institute of Health Stroke Scale (NIHSS) scores [aOR: 1.228, 95%CI: (1.054, 1.431)] were independent factors associated with malnutrition in SPBP. ROC analysis revealed that the logit model had the best predictive value [area under the curve: 0.874, 95% CI: (0.812, 0.936); specificity: 83.4%; sensitivity: 79.3%; p < 0.05]. Subgroup analysis showed that the nutritional status in dysphagic SPBP was additionally influenced by swallowing function and nutrition support mode.

Conclusion

The prevalence of malnutrition in SPBP was 60.59%. Pulmonary infection, hemoglobin level, and NIHSS score were the independent factors associated with malnutrition. Swallowing function and nutrition support mode were the factors associated with malnutrition in dysphagic SPBP.

Dysphagia after stroke: research advances in treatment interventions

After a stroke, most patients have dysphagia, which can lead to aspiration pneumonia, malnutrition, and adverse functional outcomes. Protective interventions aimed at reducing these complications remain the cornerstone of treatment. Dietary adjustments and oral hygiene help mitigate the risk of aspiration pneumonia, and nutritional supplementation, including tube feeding, might be needed to prevent malnutrition. Rehabilitative interventions aim to enhance swallowing function, with different behavioural strategies showing promise in small studies. Investigations have explored the use of pharmaceutical agents such as capsaicin and other Transient-Receptor-Potential-Vanilloid-1 (TRPV-1) sensory receptor agonists, which alter sensory perception in the pharynx. Neurostimulation techniques, such as transcranial direct current stimulation, repetitive transcranial magnetic stimulation, and pharyngeal electrical stimulation, might promote neuroplasticity within the sensorimotor swallowing network. Further advancements in the understanding of central and peripheral sensorimotor mechanisms in patients with dysphagia after a stroke, and during their recovery, will contribute to optimising treatment protocols.

Factors influencing the reduction in quadriceps muscle thickness in the paretic limbs of patients with acute stroke

BACKGROUND & AIMS

Muscle atrophy is an early event that occurs after stroke, but there are few reports on the changes in skeletal muscle thickness in acute stroke. This study investigated the factors contributing to reduced muscle thickness in patients with acute stroke.

METHODS

In total, 51 patients with stroke and the National Institute of the Health Stroke Scale (NIHSS) > 3 were included in our study. They were admitted to our hospital between July 2017 and May 2020. The quadriceps muscle thickness was measured with an ultrasound device within 2 days after admission and 14 days later. The collected data included age, sex, body mass index, stroke type, neuromuscular electrical stimulation, NIHSS, serum albumin at admission, start of enteral nutrition, Functional Oral Intake Scale (FOIS), start of mobilization and ambulation, number of physical and occupational therapy units, C-reactive protein at admission and whether surgery had been performed. These data were retrospectively retrieved from medical documents. A dietician calculated energy intake, protein intake, and energy adequacy. Multiple regression analysis was used to identify the factors associated with reduced quadriceps muscle thickness. The independent variables were NIHSS, date of start of enteral feeding, protein intake, FOIS, date of mobilization, and date of start of ambulation training.

RESULTS

The rate of change in quadriceps muscle thickness of the paretic limb was -15.3 % (interquartile range, -46.1-14.8 %). Multiple regression analysis showed that the factors responsible for the decrease in muscle thickness on the paretic side were FOIS (β: 0.376; 95 % Cl, 0.999 to 4.541) and the start date of ambulation (β: -0.378; 95 % Cl, -2.575 to -0.543), with a multiple correlation coefficient of 0.456.

CONCLUSION

The FOIS and the start date of ambulation after acute stroke were related to the rate of reduction in muscle thickness on the paretic side.

Graded nutritional interventions in patients with dysphagia after stroke: an assessment of the effectiveness of therapeutic strategies for different swallowing functions

OBJECTIVE

To evaluate the efficacy of graded nutrition intervention strategy in improving patients with different degrees of impaired swallowing function after stroke.

METHODS

According to the way of nursing, the patients were divided into two group. The main outcome measure was Kota swallowing index (WSI) score, and the secondary outcome was complications during the intervention. SF-36 scale was used to evaluate the improvement of quality of life before and intervention.

RESULTS

The WSI score in the control group was 62.34 ± 10.23 at 1 week after treatment, 70.52 ± 13.45 at 6 weeks after treatment, and 80.48 ± 9.87 at 12 weeks after treatment, while that in the intervention group was 71.45 ± 9.68 at 1 week after treatment, 75.81 ± 11.78 at 6 weeks after treatment, and 84.12 ± 14.32 at 12 weeks after treatment. The WSI scores of the intervention group were significantly higher than those of the control group (t = 5.634, p < 0.001), suggesting better swallowing function of the patients The incidence of pulmonary infection, malnutrition and gastroesophageal reflux in the intervention group was significantly lower than that in the control group (p < 0.05). There was no significant difference in throat inflammation and dehydration between the two groups (p > 0.05). In addition, graded nutrition interventions significantly improved patients' quality of life, including dimensions of physical functioning, role physics, physical pain, and social functioning.

CONCLUSION

Compared with conventional treatment, personalized graded nutrition intervention can significantly improve the swallowing function and reduce the pulmonary infection rate in patients with swallowing disorders after stroke.

Low hemoglobin levels are associated with compromised muscle health: Insights from a post-stroke rehabilitation cohort

AIM

There is limited evidence concerning the association between anemia and alterations in muscle health among hospitalized older patients. We aimed to evaluate the associations between baseline hemoglobin (Hb) levels and changes in muscle function in patients undergoing rehabilitation after stroke.

METHODS

This retrospective cohort study included consecutive hospitalized post-stroke patients. Data on serum Hb level were extracted from medical records on tests performed within 24 h of admission. The main outcomes were discharge score for the skeletal muscle mass index (SMI) obtained through bioimpedance analysis and the corresponding change in SMI during hospitalization. Other outcomes were handgrip strength (HGS) at discharge and the alteration in HGS during hospitalization. Multivariate linear regression analyses were used to determine the association between Hb levels at admission and outcomes of interest, adjusted for potential confounders.

RESULTS

Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median Hb level at admission was 13.3 [11.9, 14.5] g/dL. After fully adjusting for confounding factors, the baseline Hb level was significantly and positively associated with SMI at discharge (β = 0.046, P = 0.039) and with SMI gain (β = 0.010, P = 0.039). Further, the baseline Hb level was independently and positively associated with HGS at discharge (β = 0.058, P = 0.014) and with its change from baseline (β = 0.100, P = 0.014).

CONCLUSION

Diminished baseline Hb levels were demonstrated be correlated with compromised muscle health in patients after stroke. Evaluating anemia at the outset serves as a crucial prognostic indicator. Geriatr Gerontol Int 2024; 24: 305-311.

Deprescribing psychotropic medications is associated with improvements in activities of daily living in post-stroke patients

AIMS

To examine the effect of deprescribing psychotropic medications on activities of daily living (ADLs) and swallowing function in patients undergoing convalescent rehabilitation following a stroke.

METHODS

In this retrospective cohort study, patients who underwent convalescent rehabilitation after a stroke were divided into two groups: deprescribing (number of psychotropic medications decreased during hospitalization) and non-deprescribing (number of psychotropic medications increased or remained unchanged). The primary outcome measure was ADLs assessed using the Functional Independence-Measured Motor Activity (FIM-motor) score at discharge. A multiple linear regression analysis was conducted to determine the independent association between deprescribing psychotropic medications and rehabilitation outcomes.

RESULTS

Of the 586 patients enrolled, 128 with a mean age of 74.1 ± 12.7 years were included in the final analysis after being prescribed psychotropic medications, with 36 of them (28.1%) in the deprescribing group. Multiple linear regression analysis revealed that deprescribing psychotropic medications was independently associated with FIM-motor function at discharge.

CONCLUSIONS

Deprescribing psychotropic medications is positively associated with improvements in ADLs among patients undergoing convalescent rehabilitation after a stroke. Geriatr Gerontol Int 2024; 24: 275-282.

Prognostic Value of Dysphagia for Activities of Daily Living Performance and Cognitive Level after Stroke

Objectives

The purpose of this study was to examine the association between baseline dysphagia and the improvement of activities of daily living performance and cognitive level among inpatients after stroke.

Methods

This was a retrospective cohort study of patients undergoing convalescent rehabilitation after stroke. Dysphagia was assessed using the Food Intake LEVEL Scale. Outcomes were the motor and cognitive scores of the Functional Independence Measure (FIM) at discharge. Multiple regression analysis was performed to examine the association between dysphagia at admission and these outcomes.

Results

There were 499 participants with a median age of 74 years. A multiple regression analysis was carried out after adjusting for potential confounders including age and sex. Dysphagia at admission was independently and negatively associated with motor (β=-0.157, P<0.001) and cognitive (β=-0.066, P=0.041) FIM scores at discharge.

Conclusions

Baseline dysphagia in patients after stroke was negatively associated with improvement in performance of activities of daily living and cognitive level.

Measures for Identifying Malnutrition in Geriatric Rehabilitation: A Scoping Review

Malnutrition is a common condition in geriatric rehabilitation settings; however, the accuracy and predictive validity of the measures to identify malnutrition have not been established. The current scoping review followed the Joanna Briggs Institute's evidence synthesis manual and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews checklist. Literature published through September 2023 was searched using MEDLINE and CINAHL. The inclusion criteria selected studies reporting malnutrition measures, which include static body weight and weight loss. Identified tools were classified as nutritional screening tools, nutritional assessment tools, or diagnostic criteria. The domains of each tool/criterion and their accuracy and predictive validity were extracted. Fifty-six articles fulfilled the inclusion criteria, and six nutritional screening tools, three nutritional assessment tools, and three diagnostic criteria for malnutrition were identified. These measures consisted of various phenotypes, e.g., weight loss, causes such as inflammation/disease, and risk factors of malnutrition, e.g., functional impairment. The predictive validity of nutritional screening tools (n = 6) and malnutrition diagnostic criteria (n = 5) were inconsistently reported, whereas those for nutritional assessment tools were scarce (n = 1). These findings highlight the need to distinguish the functional impairment of nutritional origin from that of non-nutritional origin in nutritional assessment procedures, and the need to study the accuracy and the predictive validity of these measures in geriatric rehabilitation patients.

Concurrent Negative Impact of Undernutrition and Heart Failure on Functional and Cognitive Recovery in Hip Fracture Patients

Evidence on the effects of frailty, undernutrition, and heart failure (HF) on patients with hip fractures is scarce. This retrospective cohort study aimed to examine the effects of undernutrition and HF on outcomes in patients who underwent convalescent rehabilitation after hip fracture. Undernutrition was defined as body mass index (BMI) < 20.0 (Low BMI). Heart failure (HF) was defined as a B-type natriuretic peptide (BNP) > 100 (High BNP). The study outcomes included the Functional Independence Measure motor domain (FIM-motor) and cognitive domain (FIM-cognition) at discharge. To consider the effects of low BMI, high BNP, and the simultaneous presence of both ("low BMI and high BNP"), we used multivariate linear regression analyses to examine whether these were associated with the outcomes. A total of 110 (mean age 87.4 years, 24.8% male) were analyzed. As a result, low BMI (β = -0.088, p = 0.027) and high BNP (β = -0.053, p = 0.015), each alone, were significantly associated with the FIM motor at discharge, whereas the simultaneous presence of "low BMI and high BNP" was significantly associated with the FIM motor at discharge, while the strength of the association was greater than each association alone (β = -0.152, p = 0.010). Further, the simultaneous presence of "low BMI and high BNP" was significantly associated with FIM cognition at discharge (β = -0.109, p = 0.014). Comprehensive multidisciplinary management is needed, including preoperative or early postoperative nutritional support and rehabilitation, followed by rehabilitation nutrition care management, in patients with hip fracture.

The Influence of Hemoglobin and Swallowing Ability on Daily Living Activities After Hospital Discharge in Taiwanese Stroke Patients: A Longitudinal Study

OBJECTIVE

This study aimed to examine the mediating effect of swallowing ability on hemoglobin levels and activities of daily living (ADL).

DESIGN

Prospective longitudinal study.

SETTING

Two rehabilitation wards in a national referral center for Northern Taiwan, followed by discharge.

PARTICIPANTS

101 participants were admitted for first or recurrent infarction or hemorrhagic stroke and transferred to the rehabilitation ward of a medical center (N=101).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Hemoglobin data were collected from medical records. Swallowing ability and ADL were measured using the Functional Oral Intake Scale and Barthel Index, respectively, with higher scores indicating better functioning.

RESULTS

Mediation analysis performed using path analysis illustrated that hemoglobin at the time of transfer to the rehabilitation ward had a direct and positive effect on swallowing ability at 1-3 days before discharge (path coefficient=0.21, 95% confidence interval [CI]: 0.04-0.35, P=.018), and swallowing ability at 1-3 days before discharge had a direct and positive effect on ADL at 1 month after discharge (path coefficient=0.36, 95% CI: 0.13-0.57, P=.002). Hemoglobin level at the time of transfer to the rehabilitation ward did not directly influence ADL 1 month after discharge (path coefficient=0.12, 95% CI: -0.05-0.28, P=.166). These results indicate that swallowing ability substantially mediates the relation between previous hemoglobin levels and subsequent ADL.

CONCLUSION

Low hemoglobin levels and poor swallowing ability should be concurrently addressed to improve ADL performance.

Phase angle is associated with sarcopenic obesity in post-stroke patients

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.

Clinical Practice Guidelines for Oropharyngeal Dysphagia

OBJECTIVE

Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one's physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia.

METHODS

Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology.

RESULTS

Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended.

CONCLUSION

This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

Cut-off values for severe low muscle strength and skeletal muscle mass in post-acute patients with sarcopenia

AIM

This study aimed to calculate the cut-off values for severe decline in muscle strength and skeletal muscle mass in post-acute patients with sarcopenia and to determine their effect on activities of daily living.

METHODS

This retrospective cohort study included patients with sarcopenia consecutively admitted to a Japanese rehabilitation hospital between 2014 and 2016. Sarcopenia was diagnosed based on handgrip strength and skeletal muscle mass index. The outcome was the functional independence measure of motor function at discharge. Cut-off values for predicting severe decline in handgrip strength and skeletal muscle mass index were calculated separately by sex. Values below the cut-off were used to define severely low handgrip strength and severely low skeletal muscle mass index.

RESULTS

Overall, 451 patients (median age, 83 years; 61.4% women) were evaluated. The median functional independence measure of motor function score at discharge was 57. The optimal cut-off values for severely low handgrip strength were 9.0 kg for women and 14.6 kg for men, and those for severely low skeletal muscle mass index were 4.6 kg/m² for women and 5.6 kg/m² for men. Severely low handgrip strength and skeletal muscle mass index were independently associated with the functional independence measure of motor function score at discharge (β = -0.178, P = 0.005).

CONCLUSIONS

In post-acute patients with sarcopenia, a severe decline in muscle strength and skeletal muscle mass is further negatively associated with an improvement in activities of daily living. The cut-off values herein can serve as indicators to assess sarcopenia severity. Geriatr Gerontol Int 2023; ••: ••-••.

Association between deprescribing from polypharmacy and functional recovery and home discharge among older patients with sarcopenia after stroke

OBJECTIVE

Evidence regarding the association between deprescribing from polypharmacy and outcomes in the convalescent rehabilitation setting is rare. The aim of this study was to assess the association between deprescribing from polypharmacy and functional recovery and home discharge in older patients with sarcopenia after stroke.

METHODS

This retrospective cohort study was conducted at a convalescent rehabilitation hospital from January 2015 to December 2021. Among newly admitted patients in the convalescent rehabilitation ward who had experienced a stroke, patients aged ≥65 y with sarcopenia at admission and who were using at least five medications were included. Sarcopenia was diagnosed according to hand-grip strength and skeletal muscle mass index following the criteria of the Asian Working Group for Sarcopenia 2019. The primary outcome measures were functional independence-measured motor activity (FIM-motor) at discharge and home discharge. Multiple regression analysis was used to determine whether deprescribing from polypharmacy at admission was independently associated with rehabilitation outcomes.

RESULTS

Among the 264 patients with polypharmacy, 153 patients (mean age, 81.1 y; 46.4% males) were diagnosed with sarcopenia and included in the analysis. Of them, 56 (36.6%) were deprescribed from polypharmacy. Deprescribing from polypharmacy was independently associated with FIM-motor at discharge (β, 0.137; P = 0.017) and home discharge (odds ratio, 1.393; P = 0.002).

CONCLUSIONS

Because no effective pharmacotherapy for sarcopenia has been established, the novel findings of this study may be useful in the pharmacotherapy for older patients with sarcopenia after stroke. Deprescribing from polypharmacy on admission was positively associated with functional status at discharge and home discharge in older patients with sarcopenia after stroke.

Effects of Undernutrition on Swallowing Function and Activities of Daily Living in Hospitalized Patients: Data from the Japanese Sarcopenic Dysphagia Database

This retrospective cohort study examined the effects of undernutrition on swallowing function and activities of daily living in hospitalized patients. Data from the Japanese Sarcopenic Dysphagia Database were used, and hospitalized patients aged ≥20 years with dysphagia were included in the analysis. Participants were assigned to the undernutrition or normal nutritional status group based on the Global Leadership Initiative on Malnutrition criteria. The primary outcome was the Food Intake Level Scale change, and the secondary outcome was the Barthel Index change. Among 440 residents, 281 (64%) were classified under the undernutrition group. The undernutrition group had a significantly higher Food Intake Level Scale score at baseline and Food Intake Level Scale change (p = 0.001) than the normal nutritional status group. Undernutrition was independently associated with the Food Intake Level Scale change (B = -0.633, 95% confidence interval = -1.099 to -0.167) and the Barthel Index change (B = -8.414, 95% confidence interval = -13.089 to -3.739). This was defined as the period from the date of admission to the hospital until discharge or 3 months later. Overall, our findings indicate that undernutrition is associated with reduced improvement in swallowing function and the ability to perform activities of daily living.

Improvement in sarcopenia is positively associated with recovery of independence in urination and defecation in patients undergoing rehabilitation after a stroke

OBJECTIVES

This study aimed to examine the association between improvement in sarcopenia and the recovery of urinary and defecatory independence in patients undergoing convalescent rehabilitation.

METHODS

A retrospective cohort study was conducted of 849 older inpatients after a stroke. Of these, patients with sarcopenia and dependent voiding movements were targeted. Sarcopenia was assessed according to the Asian Working Group for Sarcopenia 2019, and diagnosed using handgrip strength (HGS) and skeletal muscle-mass index. Outcomes were sphincter control items of the Functional Independence Measure (FIM) at the time of discharge: urinary (FIM-Bladder) and defecation (FIM-Bowel). A score of six or higher was considered independent. A logistic regression analysis was used to determine whether sarcopenia improvement was associated with outcomes.

RESULTS

Of the patients recruited, 151 were diagnosed with sarcopenia at baseline, of whom patients dependent in urination (109 patients) and defecation (102 patients) were included in the analysis. The multivariate analysis showed that improvement in sarcopenia (odds ratio [OR]: 3.28; 95% confidence interval [CI],1.01-10.70; P = 0.048) and HGS (OR: 6.25; 95% CI, 1.45-26.90; P = 0.014) were independently associated with FIM-Bladder at the time of discharge. Improvement in HGS (OR: 4.33; 95% CI, 0.99-18.90; P = 0.048) was independently associated with FIM-Bowel at the time of discharge CONCLUSIONS: Improvement in sarcopenia and muscle strength during hospitalization may have a positive effect on urinary independence in stroke patients undergoing convalescent rehabilitation, and improvement in muscle strength may have a positive effect on defecation independence. Multidisciplinary sarcopenia treatment should be implemented in addition to conventional rehabilitation for these patients.

Relationship between Nutritional Status, Food Consumption and Sarcopenia in Post-Stroke Rehabilitation: Preliminary Data

After a stroke, patients can suffer from sarcopenia, which can affect recovery. This could be closely related to an impairment in nutritional status. In this preliminary analysis of a longitudinal prospective study, we screened 110 subjects admitted to our rehabilitation center after a stroke. We then enrolled 61 patients, who underwent a 6-week course of rehabilitation treatment. We identified a group of 18 sarcopenic patients (SG), according to the European Working Group on Sarcopenia in Older People 2 (EWGSOP2), by evaluating muscle strength with the handgrip test, and muscle mass with bioelectrical impedance analysis (BIA). With respect to the non-sarcopenic group (NSG), the SG at admission (T0) had worse muscle quality, according to the BIA-derived phase angle, and a lower score of MNA®-SF. In contrast to the NSG, the SG also exhibited lower values for both BMI and the Geriatric Nutritional Risk Index (GNRI) at T0 and T1. Moreover, 33% of the SG had a major risk of nutrition-related complications (GNRI at T0 < 92) and discarded on average more food during the six weeks of rehabilitation (about one-third of the average daily plate waste). Of note is the fact that the Barthel Index’s change from baseline indicated that the SG had a worse functional recovery than the NGS. These results suggest that an accurate diagnosis of sarcopenia, along with a proper evaluation of the nutritional status on admission to rehabilitation centers, appears strictly necessary to design individual, targeted physical and nutritional intervention for post-stroke patients, to improve their ability outcomes.

Polypharmacy and Its Association with Dysphagia and Malnutrition among Stroke Patients with Sarcopenia

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.

The Applicability of the ESPEN and EASO-Defined Diagnostic Criteria for Sarcopenic Obesity in Japanese Patients after Stroke: Prevalence and Association with Outcomes

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.

Impact of Rehabilitation Nutrition and Healthy Weight Maintenance in Motor-Complete Tetraplegia Patients

Cachexia and low muscle mass in motor-complete tetraplegia are associated with poor outcomes. This study aimed to document anthropometric, body composition, and nutritional indices in patients and to assess the effect of a comprehensive rehabilitation nutrition program in cachexia and low muscle mass. For 34 motor-complete tetraplegia in the subacute phase, a comprehensive rehabilitation nutrition program was provided for 8 to 9 weeks. Risk of malnutrition, anthropometric and body composition indices, as well as laboratory tests were assessed upon admission and at discharge. A body mass index of less than 20.2 kg/m2 was used as the cut-off value for obesity. Upon admission, 73.5% of patients were classified as obese, half were at risk of malnutrition, and 29.4% were compatible with cachexia. Compared to the premorbid state, the non-obese group showed greater weight reduction (p < 0.01) and higher prevalence of low muscle mass (p = 0.004) than the obese group. Disease duration was different between groups (p < 0.01). After rehabilitation, malnutrition risk, protein levels, and hemodynamic results improved in both groups (p < 0.05). A significant time × group interaction was observed for muscle mass, skeletal muscle mass, and appendicular lean mass index (p < 0.05). Muscle mass was maintained while fat components increased in both groups. Functional improvement was negatively correlated with an increase in fat components (p < 0.05). A personalized rehabilitation nutrition intervention improved the nutritional status, body composition, and functional outcomes in motor-complete tetraplegia. The increase in muscle mass was associated with functional gain; healthy weight gain or maintenance may improve the level of independence. Further studies to endorse this beneficial evidence of rehabilitation nutrition in the maintenance of muscle component are needed.

Changes in Nutrition-Intake Method and Oral Health through a Multidisciplinary Team Approach in Malnourished Older Patients Admitted to an Acute Care Hospital

Malnourished older inpatients referred to a nutrition support team (NST) usually receive multidisciplinary oral health management during NST intervention. However, the effects of multidisciplinary oral health management on the nutrition-intake method and oral health in these patients remain unclear. This longitudinal study aimed to investigate the effects of NST-mediated multidisciplinary oral health management on the nutrition-intake methods, oral health, and the systemic and oral factors influencing the changes in the nutrition-intake method. A total of 117 inpatients (66 men, 51 women, mean age, 71.9 ± 12.5 years) who underwent NST-mediated multidisciplinary oral health management between April 2016 and July 2019 were enrolled. Demographic data and Functional Oral Intake Scale (FOIS), Dysphagia Severity Scale (DSS), and Oral Health Assessment Tool (OHAT) scores at the time of referral to the NST and completion of the NST intervention were evaluated. After multidisciplinary NST intervention, FOIS, DSS, and OHAT scores showed significant improvements (p < 0.001). Even after adjusting the results for systemic parameters, FOIS score improvement correlated positively with the length of NST intervention (p = 0.030) and DSS score improvement (p < 0.001) as well as OHAT score improvement (p = 0.047). NST interventions with multidisciplinary oral health management could improve the nutrition-intake method.

Impact of dysphagia and its severity on long-term survival and swallowing function outcomes in patients with idiopathic inflammatory myopathies other than inclusion body myositis

OBJECTIVE

To investigate the impact of dysphagia on long-term survival and swallowing function outcomes in patients with idiopathic inflammatory myopathy other than inclusion body myositis.

METHODS

We retrospectively evaluated consecutive patients with idiopathic inflammatory myopathy other than inclusion body myositis to investigate the impact of dysphagia and its severity assessed using the Food Intake LEVEL Scale on survival and swallowing function outcomes. Time-to-event analyses were used, including Kaplan-Meier curves with log-rank (trend) test, cumulative incidence with Gray's test, and Cox proportional hazards models.

RESULTS

Of the 254 patients, 26 were dysphagic, including eight severe (Food Intake LEVEL Scale [FILS] score 2, 3) and six most severe (FILS score 1) cases; 210 were non-dysphagic, and 18 were indeterminate cases. During the 5 years after myositis diagnosis, 15 (57.7%) dysphagic and 31 (14.8%) non-dysphagic patients died, and dysphagic patients had significantly shorter survival. However, multivariate analysis showed that shorter survival was significantly associated with baseline age-adjusted Charlson Comorbidity Index (hazard ratio [HR] 1.57, 95% confidence interval [CI] 1.36-1.82]), but not with dysphagia (HR 1.46, 95% CI 0.69-3.10). Dysphagia severity was significantly associated with delayed recovery of dysphagia. In 20 non-severe or severe dysphagic cases, 19 restored swallowing function within 1 year. The most severe cases had a significantly higher cumulative probability of death before recovery from dysphagia than severe cases.

CONCLUSION

The poor survival of dysphagic myositis patients was largely confounded by advanced age and comorbid malignancies. However, patients with the most severe dysphagia had a significantly worse swallowing function and survival prognosis than those with milder dysphagia.

Polypharmacy and potentially inappropriate medications in stroke rehabilitation: prevalence and association with outcomes

Background Evidence is scarce regarding polypharmacy and potentially inappropriate medications (PIMs) in rehabilitation medicine. Aim To investigate the prevalence of polypharmacy and PIMs and their association with outcomes in stroke rehabilitation. Method A retrospective cohort study was conducted with 849 older inpatients post-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 effect of pharmacotherapy during rehabilitation, multivariate analyses were used to determine whether the presence of polypharmacy or PIMs at discharge was associated with outcomes. Results After 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 in 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 = - 0.062, P = 0.049), FIM-cognitive score (β = - 0.076, P = 0.014), energy intake (β = - 0.143, P = 0.005), and home discharge (OR: 0.458; 95% CI: 0.248, 0.847; P = 0.013). 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.

Pharmacotherapy and the Role of Pharmacists in Rehabilitation Medicine

Pharmacotherapy is important in older patients undergoing rehabilitation because such patients, especially those with frailty and physical disabilities, are susceptible to drug-related functional impairment. Drug-related problems include polypharmacy, potentially inappropriate medications (PIMs), and potential prescription omissions. These problems are associated with adverse drug events such as dysphagia, depression, drowsiness, falls and fractures, incontinence, decreased appetite, and Parkinson's syndrome, leading to impaired improvement in activities of daily living (ADL), quality of life (QOL), and nutritional status. Moreover, the anticholinergic burden is associated with impaired physical and cognitive functions. Therefore, pharmacist-centered multidisciplinary pharmacotherapy should be performed to maximize rehabilitation outcomes. Pharmacotherapy includes a review of all medications, the assessment of drug-related problems, goal setting, correction of polypharmacy and PIMs, monitoring of drug prescriptions, and reassessment of drug-related problems. The goal of pharmacotherapy in rehabilitation medicine is to optimize drug prescribing and to maximize the improvement of ADL and QOL as patient outcomes. The role of pharmacists during rehabilitation is to treat patients as part of multidisciplinary teams and as key members of nutritional support teams. In this review, we aim to highlight existing evidence regarding pharmacotherapy in older adults, including drug-related functional impairment and the association between pharmacotherapy and functional, cognitive, and nutritional outcomes among patients undergoing rehabilitation. In addition, we highlight the important role of pharmacists in maximizing improvements in rehabilitation outcomes and minimizing drug-related adverse effects.

Accuracy of Calf Circumference Measurement, SARC-F Questionnaire, and Ishii's Score for Screening Stroke-Related Sarcopenia

Objective

The purpose of this study was to investigate the accuracy of sarcopenia diagnosis in patients with stroke using calf circumference (CC), SARC-F questionnaire, and Ishii's score in comparison with the Asian Working Group for Sarcopenia 2019 (AWGS) sarcopenia diagnostic criteria.

Materials and Methods

In this cross-sectional study, a total of 364 consecutive patients with stroke were enrolled and evaluated with the CC measurement, SARC-F questionnaire, and Ishii's score. The diagnostic accuracy was analyzed.

Results

Based on the AWGS criteria, sarcopenia was present in 180 (49.5%) patients, with an age range of 49–74 (mean 63 ± 14.7) years. In all patients, the cutoff value of CC in the accuracy of diagnosing sarcopenia was 30.5 cm, with an AUC of 0.85, sensitivity of 81.8%, specificity of 90.1%, Kappa value of 0.72, and Youden index of 0.72. In the accuracy of diagnosing sarcopenia in all patients, Ishii's score had a cutoff value of 118, AUC of 0.78, sensitivity of 90.1%, specificity of 36.0%, Kappa value of 0.4, and Youden index of 0.55. For accuracy of diagnosing sarcopenia, the SARC-F questionnaire had a cutoff value of 5, AUC of 0.731, sensitivity of 94.7%, specificity of 40%, Kappa value of 0.34, and Youden index of 0.41.

Conclusions

Based on the AWGS criteria, calf circumference measurement has the optimal performance in screening stroke-related sarcopenia compared with the SARC-F questionnaire and Ishii's score. In patients with stroke, the cutoff value of calf circumference for sarcopenia is < 31 cm in men and 30 cm in women, and with an AUC of 0.85.

Nutritional Supplementation in Stroke Rehabilitation: A Narrative Review

Malnutrition is associated with increased mortality and poor functional recovery after stroke. Most guidelines for stroke rehabilitation strongly recommend nutritional screening for malnutrition. Nutritional status after stroke is related to long-term outcomes, and nutritional supplementation is recommended for stroke patients with malnutrition and those at risk of malnutrition. However, routine nutritional supplementation in stroke patients, regardless of nutritional status, is not correlated with improved functional outcomes, and nutritional supplementation is not recommended if the nutritional status is adequate. Nutritional supplementation with protein, amino acids, vitamins, and minerals positively affects recovery after stroke, with improvements seen in motor function, cognition, activities of living, and mood. However, the evidence is insufficient due to the small number of studies and the lack of well-designed randomized controlled studies. Therefore, nutritional supplementation for stroke patients in rehabilitation should not be uniform, and individual nutritional interventions based on an assessment of the patient's nutritional status should be provided.

Impaired Nutritional Condition After Stroke From the Hyperacute to the Chronic Phase: A Systematic Review and Meta-Analysis

Background

Malnutrition is common after stroke and can affect rehabilitation and healthcare costs. A comprehensive overview of stroke patients' nutritional condition from the hyperacute to the chronic phase is lacking. This systematic review aimed to investigate the prevalence of impaired nutritional condition (INC) across the continuum of care in specific phases after stroke.

Methods

CAB ABSTRACTS, Embase, MEDLINE, were used to collect studies published between 01-01-1999 and 26-08-2020. Primary and secondary outcomes were prevalence of INC and prevalence of malnutrition, respectively. Exploratory outcomes were prevalence of INC at follow-up, nutritional examination methods, prevalence of dysphagia, stroke severity, adverse events, and continent-specific prevalence of INC. A random-effects meta-analysis model was used to estimate the phase-specific pooled prevalence of INC and malnutrition.

Results

The dataset consisted of 78 study groups selected over a total of 1,244 identified records. The pooled prevalence of INC and malnutrition were 19% (95%CI:7–31) (N = 4) and 19% (95%CI:9–29) (N = 3), 34% (95%CI:25–43) (N = 34) and 26% (95%CI:18–35) (N = 29), 52% (95%CI:43–61) (N = 34) and 37% (95%CI:28–45) (N = 31), 21% (95%CI:12–31) (N = 3) and 11% (95%CI:0–24) (N = 3) and 72% (95%CI:41–100) (N = 3) and 30% (95%CI:0–76) (N = 2) in the hyperacute, acute, early subacute, late subacute, and chronic phase, respectively.

Conclusion

INC and malnutrition are highly prevalent in all stages of stroke care. Since malnutrition has been shown to negatively affect clinical outcomes, mortality, and overall healthcare expenditure in stroke survivors, it is essential to examine and monitor the nutritional status of stroke patients throughout their care journey to guide and plan, timely nutritional support and dietary modification.

Chair-Stand Exercise Improves Sarcopenia in Rehabilitation Patients 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.

Deprescribing Leads to Improved Energy Intake among Hospitalized Older Sarcopenic Adults with Polypharmacy after Stroke

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.

Weight Change during the Early Phase of Convalescent Rehabilitation after Stroke as a Predictor of Functional Recovery: A Retrospective Cohort Study

It has been reported that weight gain at discharge compared with admission is associated with improved activities of daily living in convalescent rehabilitation (CR) patients with low body mass index. Here, we investigated whether weight maintenance or gain during the early phase of CR after stroke correlates with a better functional recovery in patients with a wide range of BMI values. We conducted this retrospective cohort study in a CR ward of our hospital and included adult stroke patients admitted to the ward from January 2014 to December 2018. After ~1 month of hospitalization, the patients were classified into weight loss and weight maintenance or gain (WMG) groups based on the Global Leadership Initiative on Malnutrition criteria for weight. We adopted the motor functional independence measure (FIM) gain as the primary outcome. The motor FIM gain tended to be greater in the WMG group but without statistical significance. However, multiple regression analysis showed that WMG was significantly and positively associated with motor FIM gain. In conclusion, weight maintenance or gain in patients during the early phase of CR after stroke may be considered as a predictor of their functional recovery, and nutritional management to prevent weight loss immediately after the start of rehabilitation would contribute to this.

Rehabilitation nutrition for individuals with frailty, disability, sarcopenic dysphagia, or sarcopenic respiratory disability

PURPOSE OF REVIEW

We describe the recent advances in rehabilitation nutrition, which is especially important for disabled or frail older individuals.

RECENT FINDINGS

Recent evidence pertaining to rehabilitation nutrition conducted in rehabilitation wards and acute care hospitals has been accumulating. The combination of rehabilitation nutrition and rehabilitation pharmacotherapy is important for eliciting higher functions. The 2020 update of the clinical practice guidelines for rehabilitation nutrition provides a weak recommendation for enhanced nutritional care for patients with cerebrovascular disease, hip fracture, cancer, or acute illness who are undergoing rehabilitation. Rehabilitation nutritional care process and the International Classification of Functioning, Disability and Health-Dietetics are used to implement high-quality rehabilitation nutrition. Aggressive nutrition therapy incorporates the daily energy expenditure plus daily energy accumulation to increase body weight and muscle mass. Preventing and treating sarcopenic dysphagia should include iatrogenic sarcopenia prevention and aggressive nutrition therapy. The diagnosis criteria for respiratory sarcopenia and sarcopenic respiratory disability have been established.

SUMMARY

The International Association of Rehabilitation Nutrition and Total Nutrition Therapy Rehabilitation program may contribute to international expansion of rehabilitation nutrition. Improving evidence-practice gaps in rehabilitation nutrition and increasing national health insurance coverage of aggressive nutrition therapy and rehabilitation nutrition teams are warranted.

Association between BIA-derived Phase Angle and Sarcopenia and Improvement in Activities of Daily Living and Dysphagia in Patients undergoing Post-Stroke Rehabilitation

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.

Sarcopenia is associated with incontinence and recovery of independence in urination and defecation in post-acute rehabilitation patients

OBJECTIVE

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.

METHODS

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 P < 0.05.

RESULTS

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 P < 0.001), respectively, after adjusting for potential confounders including baseline outcome variables, FIM, and disease.

CONCLUSIONS

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.

Stored Energy Increases Body Weight and Skeletal Muscle Mass in Older, Underweight Patients after Stroke

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.

Nutritional Supplements and Neuroprotective Diets and Their Potential Clinical Significance in Post-Stroke Rehabilitation

Nutrition and rehabilitation are crucial in post-stroke recovery, especially in the elderly. Since stroke is the leading cause of long-term disability, there is a need to promote special, individually tailored nutrition strategies targeting older patients with low motor ability. Chronic stroke survivors have higher risk of developing nutrition-related chronic diseases, such as sarcopenia, anemia, type 2 diabetes mellitus and osteoporosis. Moreover, reduced motor activity, cognitive impairment and depression might be aggravated by poor malnutrition status. Accumulated data suggest that nutritional supplements and neuroprotective diets can be associated with better effectiveness of post-stroke rehabilitation as well as brain recovery. Therefore, this review focuses on preventive strategies that can improve dietary intake and change dietary patterns. We highlight the importance of neuroprotective diets, the problem of dysphagia and the role of nutrition in rehabilitation. This article focuses on potential nutritional supplements and neuroprotective diets that may have an impact on functional recovery during and after rehabilitation. Moreover, a new approach to post-stroke neuroplasticity including the use of agents from marine sources such as fucoxanthin and tramiprosate as compounds that might be used as potential neuroprotectants with antioxidative and anti-inflammatory properties is introduced.

Improvement in Oral Health Enhances the Recovery of Activities of Daily Living and Dysphagia after Stroke

OBJECTIVE

Oral problems affect rehabilitation outcomes. This study aimed to examine the association between improvement in oral health and functional outcomes in patients after stroke.

MATERIALS AND METHODS

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 of <0.05 were considered statistically significant.

RESULTS

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, p < 0.001) at discharge, after adjusting for potential confounders.

CONCLUSIONS

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.

Nutrition in the First Week after Stroke Is Associated with Discharge to Home

Malnutrition is associated with poor clinical outcomes in stroke patients. The effect of early nutritional intake after admission on home discharge is unclear. We evaluated the impact of energy intake in the first week of hospitalization of acute stroke patients on home discharge and activities of daily living (ADL). A retrospective cohort study was conducted with 201 stroke patients admitted to an acute care hospital in Japan. The energy and protein intake during the first week were evaluated. Multivariate models were used to estimate variables related to discharge destination and ADL at discharge. The cut-off point of nutritional intake for determining the discharge destination was evaluated using the receiver operating characteristic curve. Out of 163 patients included in the analysis, 89 (54.6%) and 74 (45.4%) were discharged home and elsewhere, respectively. Those discharged home had higher energy and protein intake than those discharged elsewhere. In multiple regression analysis, energy intake was independently associated with ADL at discharge and home discharge (odds ratio 1.146). Those with energy intake >20.7 kcal/kg/day had higher ADL at discharge and more patients discharged home than those with energy intake <20.7 kcal/kg/day. Energy intake during the first week affected home discharge in acute stroke patients.

Nutritional Management Enhances the Recovery of Swallowing Ability in Older Patients with Sarcopenic Dysphagia

This study assessed whether a high provided energy of ≥30 kcal/ideal body weight (IBW)/day (kg) for patients with sarcopenic dysphagia effectively improved swallowing ability and the activities of daily living (ADLs). Among 110 patients with sarcopenic dysphagia (mean age, 84.9 ± 7.4 years) who were admitted to a post-acute hospital, swallowing ability and the ADLs were assessed using the Food Intake LEVEL Scale (FILS) and the Functional Independence Measure (FIM), respectively. The primary outcome was the FILS at discharge, while the secondary outcome was the achievement of the FIM with a minimal clinically important difference (MCID) at discharge. We created a homogeneous probability model without statistically significant differences using the inverse probability of treatment weighting (IPTW) method with and without a mean provided energy of ≥30 kcal/IBW/day (kg) for a period of 1 week of hospitalization and compared the outcomes between groups. A mean provided energy of ≥30 kcal/IBW/day (kg) was achieved in 62.7% of patients. In the IPTW model, the FILS and the rates of achieved MCID of the FIM at discharge were significantly higher in the mean provided energy of ≥30 kcal/IBW/day (kg) group (p = 0.004 and p < 0.001, respectively). A high provided energy for patients with sarcopenic dysphagia may improve swallowing ability and produce clinically meaningful functional outcomes.
