Rehabilitation nutrition for sarcopenia with disability: a combination of both rehabilitation and nutrition care management

Nonsteroidal anti-inflammatory drug use is associated with improved activities of daily living and rehabilitation in older adult patients following a fracture: a retrospective cohort study

BACKGROUND

Insufficient rehabilitation due to postfracture pain can result in muscle atrophy and joint contractures, which may affect the improvement of activities of daily living (ADL). This study investigated the impact of using nonsteroidal anti-inflammatory drugs (NSAIDs) on the improvement of ADL in older adult patients with fractures admitted to a convalescent rehabilitation unit.

METHODS

Of 489 older adult patients with fractures from January 2017 to June 2019, 261 fulfilled the requirements for this retrospective cohort analysis. Patients who had convalescent rehabilitation following a fracture were categorized into two groups: those who used NSAIDs and those who did not. The functional independence measure-total gain (FIM-total) score, which was used for evaluating ADL, was the main outcome measure. We ascertained the independent relationship between NSAIDs use and rehabilitation outcomes using a multiple linear regression analysis. Covariates selected to correct bias included age, sex (male), BMI, hypertension, dementia, cardiovascular disease, cerebrovascular disease, upper limb paralysis, femoral fracture, lumbar compression fracture, thoracic compression fracture, pelvic fracture, patellar fracture, FIM-total at admission, number of drugs, acetaminophen use.

RESULTS

The mean participant age was 82.3 ± 7.4 years, 69 (26.4%) of them were men, and 94 (36%) used NSAIDs. Multiple linear regression analysis revealed that NSAIDs use was independently associated with FIM-total gain during hospitalization (β=2.311, P=0.013).

CONCLUSIONS

These findings suggest that the appropriate use of NSAIDs may play a beneficial role in maximizing rehabilitation outcomes. However, careful monitoring for potential adverse effects is essential, particularly in older adults.

The implications of bioelectrical impedance vector analysis in older adults with hip fractures

OBJECTIVES

This study used bioelectrical impedance vector analysis to assess body composition in older adults with hip fractures, comparing results with reference populations.

STUDY DESIGN

This cross-sectional study included patients aged 65 years or more who had undergone surgery for hip fracture and baseline bioelectrical impedance analysis at 50 kHz. Using raw impedance data, bioelectrical impedance vector analysis was conducted, calculating phase angle and analyzing resistance (R) and reactance (Xc) relative to height (R/H and Xc/H) on RXc graphs.

MAIN OUTCOME MEASURES

Men and women were compared with reference populations using confidence ellipses. Individual vectors were plotted against 50 %, 75 %, and 95 % tolerance ellipses and compared with international references matched for age and body mass index and a young adult group, further differentiated by sarcopenia status.

RESULTS

Among 103 patients with hip fracture (24 men, 79 women), confidence ellipses showed significant differences from reference populations (P < 0.001), with reduced Xc and lower phase angle (men: 4.3 ± 1.5°; women: 3.8 ± 1.0°), consistent with higher R/H and lower Xc/H. Most vectors lay outside the 75 % and 95 % tolerance ellipses, primarily in the lower-right and upper-right quadrants, indicating body cell mass loss and water imbalance. Only 8.3 % of men and 12.7 % of women fell within the 75 % tolerance ellipse of community-dwelling older adults. Sarcopenic patients showed greater rightward displacement, indicating more severe muscle wasting and dehydration.

CONCLUSIONS

Older hip fracture patients showed a distinct pattern on bioelectrical impedance vector analysis indicating frailty and malnutrition. Bioelectrical impedance vector analysis may effectively screen for body composition changes and nutritional status, supporting timely, multidisciplinary interventions.

Swallowing Therapy Effects on Oral Muscle Mass, Tongue Function, Swallowing, and Nutrition in Stroke Patients with Dysphagia

BackgroundDysphagia, common post-stroke, elevates clinical risks. Muscle atrophy and compromised function correlate with malnutrition and secondary sarcopenia.ObjectiveWe studied oral muscle thickness, tongue strength/endurance in post-stroke dysphagia (PSD) using sonography and Iowa Oral Performance Instrument (IOPI), and assessed swallowing therapy's impact.Methods17 healthy and 15 PSD participants were analyzed. Healthy subjects underwent baseline sonography and IOPI. PSD patients received a 3-week swallowing therapy including traditional methods, neuromuscular electrical stimulation, and IOPI-guided oral exercises. Pre/post-swallowing therapy sonography and swallowing-related evaluations were conducted.ResutlsPSD group exhibited significant differences in affected masseter muscle thickness (P = 0.001), tongue strength (P ≤ 0.001), but not posterior tongue endurance (P = 0.066). After swallowing therapy, PSD patients showed notable improvement in masseter muscle thickness (P = 0.011) and tongue strength (P = 0.005-0.009). Clinical metrics like Functional Oral Intake Scale (P = 0.004), Mini Nutritional Assessment (P = 0.007), and gait speed (P = 0.018) also improved.ConclusionsStroke-induced dysphagia correlates with reduced masseter muscle thickness, tongue strength, and endurance. Swallowing therapy enhanced masseter muscle thickness and tongue strength, potentially improving swallowing function, nutrition, and gait speed.

Predictors of recovery from dysphagia after stroke: A systematic review and meta-analysis

Objective

This systematic review aimed to identify the predictors of recovery from dysphagia after stroke in the last ten years, thereby providing an evidence-based basis for nurses to identify high-risk patients and develop individualized rehabilitation plans to improve patient prognosis.

Methods

Databases including the China National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBMdisc), China Science and Technology Journal (VIP), WanFang, PubMed, Embase, CINAHL, Web of Science, the Cochrane Library, and Scopus were retrieved to search for literature on the predictors of recovery from dysphagia after stroke. The retrieval period was from January 2013 to December 2023. The quality of studies was assessed using the Newcastle-Ottawa Scale (NOS) and the Prediction model Risk of Bias Assessment Tool (PROBAST). Meta-analysis was performed using Revman5.3 and Stata15.1 software. The review protocol has been registered with PROSPERO (CRD42024605570).

Results

A total of 1,216 results were obtained, including 599 in English and 617 in Chinese. A total of 34 studies were included, involving 156,309 patients with post-stroke dysphagia, and the rate of dysphagia recovery increased from 13.53% at 1 week to 95% at 6 months after stroke. Meta-analysis results showed that older age [OR = 1.06, 95%CI (1.04, 1.08), P < 0.001], lower BMI [OR = 1.28, 95%CI (1.17, 1.40), P < 0.001], bilateral stroke [OR = 3.10, 95%CI (2.04, 4.72), P < 0.001], higher National Institutes of Health Stroke Scale (NIHSS) score [OR = 1.19, 95%CI (1.01, 1.39), P = 0.030], tracheal intubation [OR = 5.08, 95%CI (1.57, 16.39), P = 0.007] and aspiration [OR = 4.70, 95%CI (3.06, 7.20), P < 0.001] were unfavorable factors for the recovery of swallowing function in patients with post-stroke dysphagia.

Conclusions

The lack of standardized criteria for rehabilitation assessment of post-stroke dysphagia has resulted in reported recovery rates of swallowing function exhibiting wide variability. Nurses should take targeted preventive measures for patients aged ≥70 years, low BMI, bilateral stroke, high NIHSS score, tracheal intubation, and aspiration to promote the recovery of swallowing function in patients with post-stroke dysphagia.

Sarcopenia and risk of postoperative pneumonia: a systematic review and meta-analysis

BACKGROUND

Identifying patients at risk for postoperative pneumonia and preventing it in advance is crucial for improving the prognoses of patients undergoing surgery. This review aimed to interpret the predictive value of sarcopenia on postoperative pneumonia.

METHODS

Science Citation Index Expanded (SCIE), Embase, Medline, and Cochrane Central Register of Controlled Trials were searched from inception to August 2nd, 2023 to retrieve eligible studies. The risk of bias was assessed by the Newcastle-Ottawa Scale (NOS). For each study, we computed the odds ratio (OR) and 95% confidence interval (CI) for postoperative pneumonia in patients with and without preoperative sarcopenia, and the I-squared (I2) test was employed to estimate heterogeneity.

RESULTS

The search identified 6530 studies, and 32 studies including 114,532 participants were analyzed in this review. In most of the studies included, the risk of bias was moderate. The most reported surgical site was the chest and abdomen, followed by the abdomen, chest, limbs and spine, and head and neck. Overall, patients with preoperative sarcopenia have a 2.62-fold increased risk of developing postoperative pneumonia compared to non-sarcopenic patients [OR 2.62 (I2 = 67.5%, 95%CI 2.04-3.37). Subgroup analysis focusing on different surgical sites revealed that sarcopenia has the strongest predictive effect on postoperative pneumonia following abdominal surgery (OR 4.69, I2 = 0, 95% CI 3.06-7.19). Subgroup analyses targeting different types of research revealed that sarcopenia has a stronger predictive effect on postoperative pneumonia in prospective studies (OR 5.84 vs. 2.22).

CONCLUSIONS

Our research findings indicate that preoperative sarcopenia significantly increases the risk of postoperative pneumonia. Future high-quality prospective studies and intervention studies are needed to validate the relationship between sarcopenia and postoperative pneumonia and improve patient outcomes.

Risk Factors Associated with Oral Intake Discontinuation in Hospitalized Patients with Aspiration Pneumonia: A Scoping Review

Background

Aspiration pneumonia is a prevalent condition, and understanding the risk factors associated with discontinuation of oral intake upon discharge is crucial. This study aimed to identify such factors, thereby providing valuable insights for optimizing the use of limited healthcare resources and enhancing patient and family care.

Methods

In this scoping review, data were collected through ICHUSHI using the search formula "Pneumonia-Aspiration/Thesaurus or Aspiration Pneumonia/All) and (Prognosis/Thesaurus or Prognosis/All)." The inclusion criteria encompassed Japanese patients hospitalized for aspiration pneumonia, with a clear outcome focused on the availability of oral intake. The exclusion criteria included text unavailability, studies from foreign countries, and cases involving not hospitalized patients. The risk of bias for each study was assessed using the Newcastle-Ottawa scale.

Results

Using this search formula, 1,646 articles were initially identified, culminating in the inclusion of six articles for analysis. The investigation revealed five significant risk factors: social status (age and gender), nutritional status (body mass index, Controlling Nutritional Status score, serum albumin, Basal Energy Expenditure, and low body weight), physical swallowing function (ambulatory ability before admission, Food Intake LEVEL scale (FILS), admission origin, bedridden status, Penetration-Aspiration scale, presence of residual pharyngeal material, and Basal Index), pneumonia severity (A-DROP score, a classification tool incorporating age, dehydration, oxygen demand, impaired consciousness, and hypotension), and comorbidities (pneumonia, dementia, mental illness, malignancy, chronic lower respiratory tract involvement, and renal failure).

Conclusions

This scoping review identified five key risk factors associated with oral intake discontinuation upon discharge in patients hospitalized for aspiration pneumonia, providing valuable evidence for future clinical practice.

Towards a common definition of hospital-acquired deconditioning in adults: a scoping review

BACKGROUND

Hospital-acquired deconditioning is a term used in clinical practice, describing a loss of physical and/or cognitive function associated with hospitalisation. Previous reviews have addressed interventions, its prevalence in older adults and potential assessment tools. However, each review has reported a core limitation, the need for an agreed-upon definition and diagnostic criteria for hospital-acquired deconditioning.

OBJECTIVE

We aimed to identify key components used to define hospital-acquired deconditioning in adults. We sought to do this by identifying diagnostic criteria, describing how authors operationalised Hospital- Acquired Deconditioning (HAD), and describing differences between HAD and other immobility-linked syndromes. This article focuses on how hospital-acquired deconditioning is understood and operationalised.

DESIGN

A scoping review using the Joanna Briggs Institute methodology for evidence synthesis.

ELIGIBILITY CRITERIA

Published in English after 1 January 1990, investigating adults over 18, set in inpatient rehabilitation or acute care settings, and including either a definition or description of hospital-acquired deconditioning or an outline of strategies to assess, prevent or manage hospital-acquired deconditioning.

SOURCES OF EVIDENCE

Published and grey literature, no restriction was placed on study design.

CHARTING METHODS

Relevant data, where available, was extracted from each source using a proprietary data extraction template.

RESULTS

One hundred and three articles were included from 2403 retrieved results. Thirty-three were from rehabilitation or post-acute care settings, 53 from acute care, 15 from intensive care and two from other settings. The literature was diverse in methodology and research question addressed. Hospital-acquired deconditioning was poorly defined, no consistent patterns were identified in aetiology and sequelae; diagnostic criteria were not fully agreed on.

CONCLUSIONS

The literature on hospital-acquired deconditioning is large, diverse and incomplete. Further work is required to develop a shared definition of hospital-acquired deconditioning, enabling researchers to coalesce for better understanding of the phenomenon, and clinicians, in turn, to better treat and mitigate against it.

Exploring the mediating role of depression in the relationship between sarcopenia and cardiovascular health in the middle-aged and elderly: A cross-sectional study

BACKGROUND

Cardiovascular health is influenced by various factors, including sarcopenia and depression. It has been demonstrated that sarcopenia has a negative impact on cardiovascular disease, with depression also being a contributing factor. However, the complex interplay between sarcopenia, depressive symptoms, and cardiovascular health in middle-aged and elderly populations is not fully explored.

METHODS

A total of 23,445 participants participated in China Health and Retirement Longitudinal Study and completed relevant measurements, including the Centre for Epidemiological Studies Depression Scale. The study also assessed sarcopenia and cardiovascular health score. The focus of the study was to test whether the association between sarcopenia and cardiovascular health scores was mediated by depression using PROCESS macros in R 4.3.2. Sensitivity analyses were conducted to affirm the robustness of our findings.

RESULT

The study revealed a partial mediation between sarcopenia and cardiovascular health score among the middle and elder adults, mediated by depression. Sarcopenia had a significant negative correlation with cardiovascular health score (B = -12.404, P < 0.05), and depression also showed a significant negative correlation (B = -1.515, P < 0.001).

CONCLUSION

The results support the notion that depression partially mediated the association between sarcopenia and cardiovascular health score. Therefore, interventions aimed at improving mood and addressing other cardiovascular risk factors may help alleviate the adverse effects of sarcopenia and potentially reduce the progression to cardiovascular disease.

Higher CALLY index levels indicate lower sarcopenia risk among middle-aged and elderly community residents as well as hospitalized patients

The C-reactive protein-albumin-lymphocyte (CALLY) index, which integrates albumin, lymphocytes, and C-reactive protein levels, has emerged as a novel method to assess nutritional and inflammatory statuses in patients. This study examined the correlation between the CALLY index and sarcopenia risk using two cohorts: 1804 community dwellers from the NHANES database in the United States and 139 patients from the Department of Gerontology at Kunshan Hospital, China. In the US community cohort, RCS curve analysis was used to examine the non-linear relationship between inflammatory/nutritional markers and sarcopenia, subgroup analysis was also conducted. Logistic regression was employed to evaluate the association between the CALLY index and the risk of sarcopenia in both cohorts. Results demonstrated a significant non-linear relationship between the CALLY index and the risk of sarcopenia (P < 0.001). Elevated levels of the CALLY index are independently linked to a decreased risk of sarcopenia in both community residents (OR = 0.35, 95% CI 0.20-0.57, Q3 CALLY index and OR = 0.26, 95% CI 0.11-0.56, Q4 CALLY index) and hospitalized patients (OR = 0.35, 95% CI 0.12-0.96). This finding identified low CALLY index as a conveniently measurable parameter, serving as a nutritional and inflammatory risk factor for sarcopenia.

Actual situation of nutritional management and factors related to activities of daily living ability at discharge in convalescent rehabilitation ward

Saito T, Kamachi M. Actual situation of nutritional management and factors related to activities of daily living ability at discharge in convalescent rehabilitation ward. Jpn J Compr Rehabil Sci 2024; 15: 71-78.

Objective

In this study, we aimed to investigate changes in the Geriatric Nutritional Risk Index (GNRI), a nutrition-related prognostic indicator, in our convalescent rehabilitation ward and determine how this index relates to activities of daily living (ADL) ability at discharge.

Methods

We retrospectively analyzed data of 107 patients admitted to our convalescent rehabilitation ward between April and September 2023. We used the GNRI as the nutritional risk index and Functional Independence Measure (FIM) as the ADL index.

Results

The patients' mean age was 80.0 ± 10.3 years; 38 were males and 69 females. The patients' mean body weight at admission was 51.2 ± 10.2 kg, which significantly decreased to 50.2 ± 9.4 kg at discharge (p = 0.0006). Their mean body mass index (BMI) also significantly decreased from 21.4 ± 3.4 at admission to 20.0 ± 8.2 at discharge (p = 0.002). The mean GNRI significantly decreased from 93.1 ± 8.6 at admission to 91.7 ± 8.4 at discharge (p = 0.023). The mean body weight decreased until the fourth month after admission; however, no decreasing trend after the fifth month was observed. The mean monthly energy intake gradually increased after admission and reached the calculated energy requirement of 1,415 ± 22 kcal at the fifth month. Multivariate analysis demonstrated that at discharge, the GNRI score was positively associated with the FIM score (β = 0.21, p = 0.0008).

Conclusion

Body weight and GNRI scores decreased after admission but stopped decreasing after the fifth month due to a gradual increase in energy intake. At discharge, the FIM score was positively associated with the GNRI score. We expected that active nutritional therapy from the beginning of hospitalization would increase the GNRI by the time of discharge and eventually improve ADL ability at discharge.

Nutritional care in older adults: are we doing everything? An expert opinion review

Malnutrition is a prevalent, yet often underdiagnosed and undertreated, condition in older adults. It is characterized by weight loss and/or reduced muscle mass due to diminished caloric intake, inflammation, and/or disease burden. In return, malnutrition can lead to diminished skeletal muscle functionality and disability, among others. Malnutrition plays a crucial role in the pathogenesis of two prevalent geriatric syndromes, namely sarcopenia and frailty. The complex interplay between malnutrition, sarcopenia, and frailty significantly impacts the older population, leading to increased morbidity, mortality, hospitalization rates, quality-of-life, and healthcare costs. Given the prognostic significance of malnutrition in geriatric care, recent guidelines emphasized the role of nutritional support in vulnerable populations. A group of vulnerable populations to malnutrition, sarcopenia, and frailty are older patients with hip fractures, cancer patients, and those with sarcopenic dysphagia. This article highlights the importance of individualized nutritional assessment and treatment in the management of vulnerable populations such as older patients with hip fractures, cancer, and those suffering from sarcopenic dysphagia. It presents practical protocols and guidelines that can be instrumental in enhancing the nutritional care of these groups, thereby improving their overall health outcomes.

Relationship between Improvement in Physical Activity and Three Nutritional Assessment Indicators in Patients Admitted to a Convalescent Rehabilitation Ward

We investigated the relationship between three nutritional indicators, the Mini Nutritional Assessment-Short Form (MNA-SF), Geriatric Nutritional Risk Index (GNRI), and Controlling Nutrition Status (CONUT), and physical activity at discharge in patients admitted to convalescent rehabilitation wards. The study included 1601 patients (77 ± 12 years, male 46.2%) discharged from convalescent rehabilitation wards between April 2018 and September 2023. MNA-SF, GNRI, and CONUT scores were obtained on admission. Patients were divided into two groups according to their level of Functional Independence Measure (FIM) walk score at discharge. The walking group (n = 1181, FIM walk score ≥ 5, 76 ± 13 years, male 47.2%) was significantly younger than the wheelchair group (n = 420, 79 ± 12 years, FIM walk score < 5, male 43.8%) and had significantly higher MNA-SF (6.5 ± 2.5 vs. 4.7 ± 2.4) and GNRI (93.1 ± 12.4 vs. 86.7 ± 10.9) scores and significantly lower CONUT (3.1 ± 2.3 vs. 3.9 ± 2.3) scores than the wheelchair group (all p < 0.01). Multivariate logistic regression analysis showed that age, handgrip strength, Functional Oral Intake Scale, and MNA-SF score were independently associated with walking ability at discharge (all p < 0.01). In addition, MNA-SF scores were independently associated with Rehabilitation Effectiveness. These results suggest that nutritional status, particularly MNA-SF scores on admission, is associated with improvement of physical activity at discharge.

Association of early oral intake after extubation and independent activities of daily living at discharge among intensive care unit patients: A single centre retrospective cohort study

PURPOSE

We investigated the association between the time to first post-extubation oral intake, barriers to oral intake, and the rate of activities of daily living (ADL) independence at discharge (Barthel Index score <70).

METHOD

Consecutive patients admitted to the intensive care unit, aged ≥18 years, and mechanically ventilated for ≥48 hr were retrospectively enrolled. The time to first oral intake, barriers to oral intake, daily changes, and clinical outcomes were assessed. Multiple logistic regression analysis adjusted for baseline characteristics was used to determine the association between time to first post-extubation oral intake and ADL independence.

RESULT

Among the 136 patients, 74 were assigned to the ADL independence group and 62 to the dependence group. The time to first post-extubation oral intake was significantly associated with ADL independence (adjusted p = < 0.001) and was a predictor of ADL independence at discharge. Respiratory and dysphagia-related factors (odds ratio [OR] 0.35; 95% confidence interval [CI] 0.15-0.82, p = 0.015 and OR 0.07; CI 0.01-0.68, p = 0.021, respectively) were significantly associated with the ADL independence at discharge.

CONCLUSION

Respiratory and dysphagia-related factors, as barriers to the initiation of oral intake after extubation, were significantly associated with ADL independence at discharge.

Development of a prediction model for cognitive impairment of sarcopenia using multimodal neuroimaging in non-demented older adults

INTRODUCTION

Despite prior research on the association between sarcopenia and cognitive impairment in the elderly, a comprehensive model that integrates various brain pathologies is still lacking.

METHODS

We used data from 528 non-demented older adults with or without sarcopenia in the Catholic Aging Brain Imaging (CABI) database, containing magnetic resonance imaging scans, positron emission tomography scans, and clinical data. We also measured three key components of sarcopenia: skeletal muscle index (SMI), hand grip strength (HGS), and the five times sit-to-stand test (5STS).

RESULTS

All components of sarcopenia were significantly correlated with global cognitive function, but cortical thickness and amyloid-beta (Aβ) retention had distinctive relationships with each measure. In the path model, brain atrophy resulting in cognitive impairment was mediated by Aβ retention for SMI and periventricular white matter hyperintensity for HGS, but directly affected by the 5STS.

DISCUSSION

Treatments targeting each sub-domain of sarcopenia should be considered to prevent cognitive decline.

HIGHLIGHTS

We identified distinct impacts of three sarcopenia measures on brain structure and Aβ. Muscle mass is mainly associated with Aβ and has an influence on the brain atrophy. Muscle strength linked with periventricular WMH and brain atrophy. Muscle function associated with cortical thinning in specific brain regions. Interventions on sarcopenia may be important to ease cognitive decline in the elderly.

Biological basis and treatment of frailty and sarcopenia

In an ageing society, the importance of maintaining healthy life expectancy has been emphasized. As a result of age-related decline in functional reserve, frailty is a state of increased vulnerability and susceptibility to adverse health outcomes with a serious impact on healthy life expectancy. The decline in skeletal muscle mass and function, also known as sarcopenia, is key in the development of physical frailty. Both frailty and sarcopenia are highly prevalent in patients not only with advanced age but also in patients with illnesses that exacerbate their progression like heart failure (HF), cancer, or dementia, with the prevalence of frailty and sarcopenia in HF patients reaching up to 50-75% and 19.5-47.3%, respectively, resulting in 1.5-3 times higher 1-year mortality. The biological mechanisms of frailty and sarcopenia are multifactorial, complex, and not yet fully elucidated, ranging from DNA damage, proteostasis impairment, and epigenetic changes to mitochondrial dysfunction, cellular senescence, and environmental factors, many of which are further linked to cardiac disease. Currently, there is no gold standard for the treatment of frailty and sarcopenia, however, growing evidence supports that a combination of exercise training and nutritional supplement improves skeletal muscle function and frailty, with a variety of other therapies being devised based on the underlying pathophysiology. In this review, we address the involvement of frailty and sarcopenia in cardiac disease and describe the latest insights into their biological mechanisms as well as the potential for intervention through exercise, diet, and specific therapies.

Effect of Sarcopenia on Swallowing in Patients With Head and Neck Cancer

OBJECTIVE

Sarcopenia, characterized by decreased skeletal muscle mass, is associated with poorer oncologic outcomes in head and neck cancer (HNC) patients. The effect of sarcopenia on swallowing following HNC treatment is unknown. This study aims to investigate the association of sarcopenia and swallowing dysfunction in patients treated for HNC.

STUDY DESIGN

Retrospective cohort study.

SETTING

Academic medical center.

METHODS

Pretreatment sarcopenia was assessed using the skeletal muscle index calculated from cross-sectional imaging at the third cervical vertebra. Feeding tube dependence, patient-reported dysphagia, and swallowing safety were assessed before and after treatment with the Functional Oral Intake Scale, Eating Assessment Tool-10, and Penetration Aspiration Scale, respectively. The association between sarcopenia and swallowing dysfunction was evaluated.

RESULTS

A total of 112 patients were included, 84 males (75%) and 28 females (25%). A total of 69 (61.6%) had sarcopenia prior to initiating HNC therapy. Sarcopenia was significantly associated with an elevated risk of patient-reported dysphagia (odds ratio [OR] = 2.71 [95% confidence interval, CI, 1.12-6.79]; P < .05). Multivariate logistic regression demonstrated that sarcopenia (OR = 15.18 [95% CI, 1.50-453.53]; P < .05) is an independent predictor for aspiration following treatment for HNC.

CONCLUSION

Patients with pretreatment sarcopenia had higher rates of dysphagia before treatment and were more likely to develop aspiration after completion of HNC therapy. Sarcopenia is readily measured using cross-sectional imaging and may be useful for identifying patients at risk of swallowing dysfunction and those most likely to benefit from prehabilitation efforts.

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.

Swallowing Rehabilitation With Neuromuscular Electrical Stimulation for Sarcopenic Dysphagia: A Case Report

Sarcopenic dysphagia is defined as dysphagia caused by sarcopenia of the whole body and swallowing-related muscles. We present a case of sarcopenic dysphagia with improved swallowing function after strength training of swallowing-related muscles using neuromuscular electrical stimulation (NMES). A 78-year-old man was admitted to our hospital with an intraductal papillary mucinous tumor of the pancreatic duct. After admission, the patient developed aspiration pneumonia and was placed on strict bed rest without oral intake, which resulted in progressive malnutrition. At the start of swallowing rehabilitation, he had whole-body sarcopenia, nutritional impairment, and weakness in swallowing-related muscles, with a maximum tongue pressure of 21.4 kPa and an opening force of 5.1 kg. In the videofluoroscopic swallowing study, he aspirated 3 cc of a moderately thick liquid. Consequently, as part of swallowing rehabilitation, strengthening training of swallowing-related muscles with NMES was undertaken for about three weeks. As a result, the maximum tongue pressure and opening force improved to 28.4 kPa and 6.8 kg, respectively. A subsequent videofluoroscopic swallowing study showed no obvious aspiration during any procedure. The patient was discharged on the 86th day on a regular diet. As a component of swallowing rehabilitation, NMES may offer therapeutic benefits for patients with sarcopenic dysphagia.

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.

The impact of energy and protein intake on rehabilitation efficiency in convalescent patients

BACKGROUND AND OBJECTIVES

It is well known that more than 40% of patients in the convalescent rehabilitation settings suffer from malnutrition, and that appropriate nutrition management can improve rehabilitation outcomes.

METHODS AND STUDY DESIGN

In this study, we used a change in motor score of Functional Independent Measure (FIM-M) of convalescent rehabilitation to investigate whether daily energy intake could influence the rehabilitation outcomes. Of the 217 patients hospitalized in our convalescent rehabilitation ward (CRW) between September 2016 and February 2017, 162 met the eligibility criteria for this study.

RESULTS

For a 25 kcal/ ideal body weight (IBW)/day cutoff point, 76 patients consumed more than 25 kcal/IBW/day of energy (H-E group), and 86 patients consumed up to 25 kcal/IBW/day of energy (L-E group). Patients in the L-E group had poorer nutritional status than those in the H-E group at CRW admission. Moreover, patients in the L-E group lost some body weight (BW) during hospitalization, whereas patients in the H-E group gained some BW. Furthermore, the FIM-M efficiency in the L-E group was significantly lower than that in the H-E group.

CONCLUSIONS

We concluded that appropriate nutritional management given to rehabilitation patients for adequate energy intake to maintain or gain their BW could maximize the outcome of convalescent rehabilitation.

The effectiveness of protein supplementation combined with resistance exercise programs among community-dwelling older adults with sarcopenia: a systematic review and meta-analysis

OBJECTIVES

The combination of protein supplementation and resistance exercise shows promise for improving and maintaining muscle mass, strength, and performance in older adults with sarcopenia. This systematic review aimed to evaluate the effects of this combination on muscle mass, muscle strength, and physical performance in community-dwelling older adults with sarcopenia.

METHODS

We conducted a comprehensive search of 4 electronic databases: PubMed, Scopus, Embase, and the MEDLINE Library. The search covered literature from January 2013 to January 2023 and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two independent reviewers assessed the methodological quality of each study using the standard critical appraisal tool from the Joanna Briggs Institute (JBI). Meta-analysis was performed with the JBI Sumari program.

RESULTS

The review included 7 randomized controlled trials and 1 quasi-experimental study, encompassing a total of 854 participants aged 60 years and above. The study durations ranged from 10 weeks to 24 weeks. An analysis of standardized mean differences (SMDs) showed that protein supplementation combined with resistance exercise significantly increased muscle mass (SMD, 0.95; 95% confidence interval [CI], 0.13 to 1.78; p<0.05) and muscle strength (SMD, 0.32; 95% CI, 0.08 to 0.56; p<0.05).

CONCLUSIONS

Although the limited number of randomized controlled trials restricts the robustness of our conclusions, the evidence suggests that protein supplementation combined with resistance exercise is effective in enhancing muscle mass and strength in community-dwelling older adults with sarcopenia.

The importance of taste on swallowing function

The world's population is aging. Pneumonia is the leading cause of death among the older adults, with aspiration pneumonia being particularly common. Aspiration pneumonia is caused by a decline in swallowing function. Causes can include age-related sarcopenia of swallowing muscles, cognitive decline, cerebrovascular and other diseases or even changes in individual taste preference. Currently, the main treatment approach for dysphagia is resistance training of swallowing-related muscles. This approach has not been effective and establishment of novel methods are required. In this review, we introduce and discuss the relationship between taste, taste preference, carbonation and swallowing function. Taste and preference improve swallowing function. Recently, it has been shown that a carbonated beverage that combines the functionality of a thickening agent, the appeal of taste, and the stimulation of carbonation improves swallowing function. This may be very useful in the recovery of swallowing function. It is important to note that deliciousness is based not only on taste and preference, but also on visual information such as food form. Umami taste receptors are expressed not only in taste buds but also in skeletal muscle and small intestine. These receptors may be involved in homeostasis of the amino acid metabolic network, i.e., the process of amino acid ingestion, intestine absorption, and storage in skeletal muscle. Proper stimulation of umami receptors in organs other than taste buds may help maintain nutritional status and muscle mass. Umami receptors are therefore a potential therapeutic target for dysphagia.

Undernutrition in obese older adults by fat percentage

OBJECTIVE

The prevalence of obesity by fat percentage has seen a steady increase in older adults in recent years, secondary to increases in fat mass in body composition, even in healthy aging. Malnutrition is a common geriatric syndrome with serious clinical outcomes. Increases in fat mass and waist circumference with healthy aging should not prevent the risk of malnutrition from being masked. Malnutrition is often ignored in obese older people due to low BMI cut-off values in many screening tests. The present study seeks to raise awareness of the need to assess the frequency of undernutrition and related factors in obese older adults.

METHODS

The data of 2013 community-dwelling patients aged ≥ 60 years who applied to a university geriatrics outpatient clinic between April 2012 and November 2022 were analyzed retrospectively, of which 296 were found to be obese based on fat percentage and were included in the study. Demographic data and the presence of any geriatric syndromes were obtained retrospectively from the patient files, functional status was assessed using the KATZ Activities of Daily Living (ADL) Scale and the LAWTON-BRODY Instrumental Activities of Daily Living Scale (IADL); frailty was screened using FRAIL-scale; and the sample was assessed for malnutrition using the Mini Nutritional Assessment-Short Form (MNA-SF), with undernutrition defined as an MNA-SF score of [Formula: see text] The patients' fat percentage and weight were measured using a bioimpedance analyzer. Fatty obesity was defined using the Zoico methodology (fat percentage [Formula: see text] 27.3% for males, [Formula: see text] 40.7% for females)[Formula: see text] handgrip strength (HGS) was measured using a hand dynamometer, and probable sarcopenia was defined as low HGS based on regional cut-off values (35 kg for males, 20 kg for females).

RESULTS

The mean age of the 296 fatty obese older adults (102 males/194 females) was 74.4 + 6.5 years, and the median fat was 42.2% (27.4-59.5). Undernutrition was detected in 19.6% of the patients based on MNA-SF screening. A univariate analysis revealed age, sex, educational status, daily physical activity status, depression, difficulty in swallowing, chewing difficulty, probable sarcopenia, number of chronic diseases, and IADL to be associated with undernutrition, while a multivariate logistic regression analysis revealed depression [OR = 3.662, 95% CI (1.448-9.013), p = 0.005] and daily physical activity status [OR:0.601, 95% CI (0.417-0.867), p = 0.006] to be independently associated with malnutrition in obese older adults based on fat percentage.

CONCLUSION

 The present study clarifies the significance of undernutrition in obese older adults also in our country, and recommends undernutrition screening to be carried out, by fat percentage, on obese older adults, especially with depression and low daily physical activity.

The prevalence and factors associated with sarcopenia in Thai older adults: A systematic review and meta-analysis

Objective

This systematic review and meta-analysis aimed to assess the prevalence and identify factors associated with sarcopenia in older Thais.

Methods

Research studies were searched in online databases, including PubMed, Embase, Scopus, and Thai-Journal Citation Index. The articles included in this review were limited to being published between January 1, 2013 and January 31, 2023 and observational study designs. The research quality was evaluated using the Joanna Briggs Institute (JBI) critical appraisal tool for prevalence studies. A meta-analysis was performed using the JBI SUMARI software. The review protocol has been registered on PROSPERO with the assigned ID CRD42023420514.

Results

A total of 265 research articles were initially identified, out of which 17 articles were included in this study, including a total of 4,668 participants aged 60 years and over, consisting of 1,380 (29.6%) men and 3,288 (70.4%) women. The overall prevalence of sarcopenia in Thai older adults was 20.7% (95% CI 14.4%-27.8%). Subgroup analysis of the sarcopenia prevalence based on the study areas revealed that the prevalence was 33.4% (95% CI 28.7%-38.3%) in hospitalized individuals, 23.2% (95% CI 12.5%-35.9%) in outpatient clinic settings, and 17.3% (95% CI 9.4%-26.8%) in community-living older adults. Advanced age (OR = 4.60, 95% CI 3.07-6.91), being male (OR = 2.30, 95% CI 1.37-3.85), low body mass index (BMI) (OR = 8.95, 95% CI 6.05-13.25), and malnutrition (OR = 2.78, 95% CI 2.09-3.70) are strong predictors of sarcopenia in older adults in Thailand.

Conclusions

This systematic review represents the first assessment of the overall prevalence and factors associated with sarcopenia in Thai older adults, indicating its significant concern within this population. These findings are of importance for public health management aimed at preventing and managing sarcopenia in the country.

Usefulness of the GLIM criteria to predict recovery of activities of daily living in older adults with post-acute stroke

OBJECTIVES

The usefulness of malnutrition diagnosed using the Global Leadership Initiative on Malnutrition (GLIM) criteria as a predictor of recovery of activities of daily living is unclear. This study aimed to investigate whether baseline malnutrition diagnosed using the GLIM criteria was predictive of recovery of activities of daily living in older patients with post-acute stroke.

MATERIALS AND METHODS

A retrospective cohort study was conducted in patients aged ≥70 years with post-acute stroke. The outcome was activities of daily living measured using the motor domain of the Functional Independence Measure (FIM-motor) score at discharge. Participants were classified as malnourished or non-malnourished according to the GLIM criteria. Multivariate linear regression analyses were performed to determine whether baseline malnutrition diagnosed using the GLIM criteria was predictive of the FIM-motor score at discharge. The analysis was adjusted for clinically relevant covariates associated with rehabilitation outcomes after stroke.

RESULTS

A total of 236 patients (mean age, 80.0 years; female, 54.2%) were included in the analysis. On admission, 83 (35.2%) patients were diagnosed with malnutrition. Multivariate linear regression analyses showed that malnutrition diagnosed using the GLIM criteria was predictive of the FIM-motor score at discharge (β = -0.347, P < 0.001).

CONCLUSIONS

Identifying malnutrition using the GLIM criteria is useful for predicting recovery of activities of daily living in older patients with post-acute stroke.

Hospital-associated sarcopenia and the preventive effect of high energy intake along with intensive rehabilitation in patients with acute stroke

OBJECTIVES

Hospital-associated sarcopenia is prevalent and associated with poor outcomes in acutely admitted patients. Prevention of developing sarcopenia during hospitalization is an important factor in stroke management. Therefore, this study aimed to investigate whether energy intake and rehabilitation duration contribute to the prevention of hospital-associated sarcopenia in patients with acute stroke.

METHODS

Patients with acute stroke were included in this study. Energy intake during the first week of hospitalization was classified as "high" or "low" based on the reported cutoff value. Rehabilitation time during hospitalization was classified as "intense" or "mild" based on the median. The four groups were compared based on the combinations of high or low energy intake and intense or mild rehabilitation. The primary outcome was the development of sarcopenia during hospitalization. The secondary outcome was the Functional Independence Measure motor item gain during hospitalization. Multivariate analysis was performed with the primary or secondary outcome as the dependent variable and the effect of each group on the outcome was examined.

RESULTS

A total of 112 participants (mean age = 70.6 y; 63 men) were included in the study. Multivariate analysis found that high × intense (odds ratio = 0.113; P = 0.041) was independently associated with the development of sarcopenia during hospitalization (i.e., hospital-related sarcopenia). High × intense (β = 0.395; P < 0.001) was independently associated with the gain of Functional Independence Measure motor items.

CONCLUSIONS

In patients with acute stroke, the combination of high energy intake and adequate rehabilitation time is associated with prevention of hospital-associated sarcopenia.

Predictive Value of the Hemoglobin-Geriatric Nutritional Risk Index in Patients with Heart Failure

Malnutrition prevails among patients with heart failure (HF), increasing the likelihood of functional decline. We assessed the predictive value of the Hemoglobin-Geriatric Nutritional Risk Index (H-GNRI)—combining hemoglobin and the Geriatric Nutritional Risk Index (GNRI)—on prognosis in older patients with HF. We used the JMDC multicenter database to examine the potential associations between malnutrition risk and other outcome measures. The patients were categorized as low- (H-GNRI score = 2), intermediate- (H-GNRI score = 1), or high-risk (H-GNRI score = 0) based on their H-GNRI scores. The primary outcome measure was the Barthel Index (BI) gain; the secondary outcomes included the BI at discharge, the BI efficiency, length of hospital stay, in-hospital mortality, discharge to home or a nursing home, and hospitalization-associated disability. We analyzed 3532 patients, with 244 being low-risk, 952 being intermediate-risk, and 2336 being high-risk patients. The high-risk group of patients had significantly lower BI values at discharge, lower BI gains, reduced BI efficiency values, and prolonged hospital stays compared to those in the low-risk group. The high-risk patients also had higher in-hospital mortality rates, lower rates of discharge to home or a nursing home, and greater incidences of a hospitalization-associated disability in comparison to the low-risk group. The H-GNRI may serve as a valuable tool for determining prognoses for patients with HF.

Impact of body mass index on outcomes of inpatients with vertebral compression fractures in Japan: A retrospective cohort study

AIM

The present study examined the relationship between body mass index and the ability to perform the activities of daily living in patients with vertebral compression fractures.

METHODS

A retrospective cohort analysis of patients aged >65 years hospitalized with a vertebral compression fracture was carried out using a nationwide database in Japan. Body mass index was categorized as underweight (<18.5 kg/m2 ), normal weight (18.5-22.9 kg/m2 ), overweight (23.0-27.4 kg/m2 ) and obese (≥27.5 kg/m2 ) according to the World Health Organization criteria for the Asia-Pacific region. The primary outcome was Barthel Index gain, namely, the change in the Barthel Index score at discharge from that at admission. Secondary outcomes were the length of hospital stay and readmission within 30 days of discharge.

RESULTS

Among 41 423 participants, 24.5% were classified as underweight, excluding those with missing body mass index data. The underweight group had a significantly lower Barthel Index gain than the normal, overweight and obese groups (median 20 vs 25 vs 30 vs 30, respectively, P < 0.001). The underweight group also had longer hospital stays and higher 30-day readmission rates than the other groups. A multivariable analysis showed that being underweight was independently associated with a Barthel Index gain -3.63 points (95% confidence interval -4.58 to -2.68) lower than normal weight. Furthermore, being underweight was an independent variable affecting the length of hospital stay and readmission within 30 days (P < 0.001).

CONCLUSIONS

In patients with vertebral compression fractures, being underweight leads to lower Barthel Index scores, longer hospital stays and increased readmissions within 30 days of discharge. Geriatr Gerontol Int 2023; 23: 788-794.

Implementation of Nutritional Assessment and Counseling in Physical Therapy Treatment: An Anonymous Cross-Sectional Survey

In the context of the evolving role of Physical Therapists (PTs) in health promotion, this study explored the incorporation of nutritional assessment and counseling into PTs' professional practice in Israel. Using an anonymous cross-sectional survey design, the research gauged PTs' professional background, nutritional knowledge, lifestyle habits, and the extent of nutritional care integration. Our survey gathered data from 409 certified PTs in Israel, revealing inadequate nutritional knowledge, commendable nutritional lifestyles, and limited nutritional care integration. Participants with over 13 years of clinical experience demonstrated significantly higher levels of nutritional assessment and counseling integration within their physical therapy practices. Workplace setting, nutritional lifestyle, and nutritional knowledge emerged as significant predictors for nutritional care integration. Specifically, working in outpatient clinics and possessing better nutritional lifestyles and knowledge were associated with the increased integration of nutritional assessment and counseling within physical therapy practice. These findings underscore the need for targeted interventions and formal nutrition education to bridge the knowledge gaps and optimize patient care. These results advocate for comprehensive nutrition education in physical therapy curricula and the fostering of PTs as role models. Integrating nutrition care could empower PTs to enhance patient outcomes and fulfill their role in preventive healthcare.

The impact of sarcopenia on esophagectomy for cancer: a systematic review and meta-analysis

BACKGROUND

Esophagectomy is the gold-standard treatment for locally advanced esophageal cancer but has high morbimortality rates. Sarcopenia is a common comorbidity in cancer patients. The exact burden of sarcopenia in esophagectomy outcomes remains unclear. Therefore, this systematic review and meta-analysis were performed to establish the impact of sarcopenia on postoperative outcomes of esophagectomy for cancer.

METHODS

We performed a systematic review and meta-analysis comparing sarcopenic with non-sarcopenic patients before esophagectomy for cancer (Registration number: CRD42021270332). An electronic search was conducted on Embase, PubMed, Cochrane, and LILACS, alongside a manual search of the references. The inclusion criteria were cohorts, case series, and clinical trials; adult patients; studies evaluating patients with sarcopenia undergoing esophagectomy or gastroesophagectomy for cancer; and studies that analyze relevant outcomes. The exclusion criteria were letters, editorials, congress abstracts, case reports, reviews, cross-sectional studies, patients undergoing surgery for benign conditions, and animal studies. The meta-analysis was synthesized with forest plots.

RESULTS

The meta-analysis included 40 studies. Sarcopenia was significantly associated with increased postoperative complications (RD: 0.08; 95% CI: 0.02 to 0.14), severe complications (RD: 0.11; 95% CI: 0.04 to 0.19), and pneumonia (RD: 0.13; 95% CI: 0.09 to 0.18). Patients with sarcopenia had a lower probability of survival at a 3-year follow-up (RD: -0.16; 95% CI: -0.23 to -0.10).

CONCLUSION

Preoperative sarcopenia imposes a higher risk for overall complications and severe complications. Besides, patients with sarcopenia had a lower chance of long-term survival.

Weaning from Tube Feeding Post Stroke by Eating, Swallowing, and Nutritional Support In-Home: A Case Report

In many cases, enteral tube feeding is begun after stroke without adequate assessment of feeding ability, swallowing function, and nutritional status. A 72-year-old man was recovering at home after a stroke and consulted us because he wanted to resume taking food by mouth. He had tube feeding for 13 months after the stroke. We offered him feeding and swallowing training and proper nutrition guidance by visiting dental staff and managerial dietitians at home and concluded the patient was sufficiently able to take oral food. After 4 months, the patient was completely weaned from tube feeding.

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; ••: ••-••.

Distinct contributions of muscle mass and strength stratified by nutritional status to physical activity in patients with chronic obstructive pulmonary disease

BACKGROUND

Physical activity is one of the most important prognostic factors for patients with chronic obstructive pulmonary disease (COPD). Physical activity correlates significantly with skeletal muscle mass and strength. Pulmonary rehabilitation has been conducted to improve physical activity, but its effectiveness has been inconsistent. Nutritional status is also related to physical activity in patients with COPD. The relationships between skeletal muscle mass, strength, and nutritional status evaluated using the Mini Nutritional Assessment Short Form (MNA-SF) were investigated. How nutritional status alters the relationships between physical activity, exercise capacity, skeletal muscle mass, and strength was also investigated.

METHODS

This retrospective, cross-sectional study enrolled 81 outpatients with COPD. In all patients, physical activity, exercise capacity, body composition assessment, and MNA-SF were assessed. The relationships between physical activity, exercise capacity, skeletal muscle mass, and strength were examined according to the MNA-SF.

RESULTS

The MNA-SF high group had significantly higher skeletal muscle mass than the MNA-SF low group when skeletal muscle strength was the covariate. In the MNA-SF low group, physical activity positively correlated with skeletal muscle mass. In the MNA-SF high group, physical activity positively correlated with skeletal muscle strength.

CONCLUSIONS

This study showed that the nutritional status of patients with COPD alters the relationship between physical activity and skeletal muscle mass or strength. Optimizing rehabilitation with nutrition interventions according to nutritional status might improve physical activity in patients with COPD.

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.

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.

Association between sarcopenia and oral functions in community-dwelling older adults: A cross-sectional study

BACKGROUND

Few studies have examined the state of oral function in older adults with sarcopenia. We assessed the oral functions of community-dwelling older adults with sarcopenia from multiple perspectives to clarify their potentially low oral function.

METHODS

A total of 1517 (86.2%; 990 women, 527 men; mean age 76.1 ± 7.6 years) participants were included in this study. Grip strength, gait speed and skeletal muscle mass index were assessed, and sarcopenia was evaluated according to the criteria of the Asian Working Group for Sarcopenia 2019. The degree of tongue coating, oral moisture, occlusal force, tongue-lip motor function, tongue pressure, masticatory function and swallowing function were assessed. The criteria for oral hypofunction (a disease that is a combination of multiple low oral functions) were used to assess oral function. Statistical analyses were performed using Kolmogorov-Smirnov test, unpaired t-test, Mann-Whitney U test, χ² test, and univariate and multivariable logistic regression analyses, with each oral function as the dependent variable and sarcopenia as one of the independent variables. The significance level was set at P < 0.05.

RESULTS

The prevalence rates of sarcopenia and severe sarcopenia were 14.2% and 3.8%, respectively. The prevalence of oral hypofunction was 39.9%. Compared with the robust group, the sarcopenia and severe sarcopenia groups tended to have a higher frequency of the following components (all P < 0.01): low occlusal force, low tongue-lip motor function, low tongue pressure, low masticatory function, low swallowing function and oral hypofunction. Univariate logistic regression analysis showed that sarcopenia was associated with low occlusal force, low tongue-lip motor function, low tongue pressure, low masticatory function, low swallowing function and oral hypofunction. The odds ratios and 95% confidence intervals of sarcopenia for each oral function were 2.62 [2.00, 3.43], 2.21 [1.69, 2.89], 3.66 [2.79, 4.81], 3.23 [2.46, 4.25], 1.66 [1.26, 2.20] and 3.59 [2.72, 4.72], respectively. Multivariable logistic regression analysis showed that sarcopenia was associated with low occlusal force (1.63 [1.10, 2.40]), low tongue pressure (2.28 [1.65, 3.15]), low masticatory function, (1.94 [1.27, 2.97]), low swallowing function (1.64 [1.17, 2.28]) and oral hypofunction (2.17 [1.52, 3.09]).

CONCLUSIONS

This study demonstrated that multiple aspects of oral function were low among community-dwelling older adults with sarcopenia. The potential decline in oral functions in older adults with sarcopenia may have been overlooked until now. This study indicates the need for dental perspectives in intervening with older adults with sarcopenia and the need to encourage them to see dental professionals.

Effects of muscle mass and muscle quality estimated by phase angle on functional outcomes in older patients undergoing rehabilitation: A prospective cohort study

BACKGROUND

Both skeletal muscle mass and muscle quality are important predictors of poor prognosis in older patients. However, the effects of muscle mass and muscle quality estimated by the phase angle (PhA) on functional outcomes in older patients undergoing rehabilitation have yet to be reported. This study aimed to investigate whether appendicular skeletal muscle index (SMI) and muscle quality estimated by PhA were independently associated with activities of daily living (ADL) and physical function in older patients undergoing rehabilitation.

METHODS

This prospective cohort study included older patients in a subacute rehabilitation hospital (n = 443). Baseline SMI and PhA were measured using bioelectrical impedance analysis, and low SMI or low PhA were determined using each cutoff value. The primary outcomes were ADL abilities measured using the functional independence measure for motor function (FIM-M) score and physical function measured using the short physical performance battery (SPPB) score at hospital discharge. Association between low SMI and low PhA and FIM-M or SPPB scores at discharge were determined using multiple regression analysis adjusted for confounding factors.

RESULTS

There were significant differences between the normal- and low-PhA groups in the FIM-M and SPPB scores at discharge (P < 0.001). In multiple regression analysis, low PhA was independently associated with FIM-M (β = -0.109, P = 0.013) and SPPB scores (β = 0.535, P < 0.001) at discharge; however, low SMI was not independently associated with these functional outcomes.

CONCLUSION

Decreased muscle quality estimated by the PhA was independently associated with poor ADL abilities and poor physical function in older patients undergoing rehabilitation.

The Effectiveness of Family Medicine-Driven Interprofessional Collaboration on the Readmission Rate of Older Patients

Interprofessional collaboration (IPC) for older patient care among family physicians, dentists, therapists, nutritionists, nurses, and pharmacists in the rural hospital care of older patients could improve the hospital readmission rate. However, there is a lack of interventional studies on IPC for improving the readmission rate among Japanese older patients in rural hospitals. This quasi-experimental study was performed on patients >65 years who were discharged from a rural community hospital. The intervention was IPC implementation with effective information sharing and comprehensive management of older patients’ conditions for effective discharge and readmission prevention; implementation started on 1 April 2021. The study lasted 2 years, from 1 April 2021 to 31 March 2022 for the intervention group and from 1 April 2020 to 31 March 2021 for the comparison group. The average participant age was 79.86 (standard deviation = 15.38) years and the proportion of men was 45.0%. The Cox hazard model revealed that IPC intervention could reduce the readmission rate after adjustment for sex, serum albumin, polypharmacy, dependent condition, and Charlson Comorbidity Index score (hazard ratio = 0.66, 95% confidence interval: 0.54−0.81). Rural IPC intervention can improve inpatient care for older patients and decrease readmission rates. Thus, for effective rural IPC interventions, family physicians in hospitals should proactively collaborate with various medical professionals to improve inpatient health outcomes.

Impact of sarcopenia on postoperative pulmonary complications after gastric cancer surgery: A retrospective cohort study

Background

Few studies have investigated the relationship between sarcopenia and postoperative pulmonary complications (PPCs) after gastric cancer surgery. This study aimed to explore the impact of sarcopenia on PPCs in patients who had undergone gastric cancer surgery.

Methods

We included patients who underwent a transabdominal radical gastrectomy between June 2016 and October 2020. Patients were divided into two groups according to the median prevalence rate of lumbar triplane skeletal muscle index (L3 SMI): sarcopenia group (≤37.5% percentile in male and female group) and non-sarcopenia group (>37.5% percentile in male and female group). Baseline characteristics, intraoperative and postoperative conditions, pulmonary complications, and overall complications were compared between the two groups. The primary outcome was the incidence of PPCs. The secondary outcomes were overall postoperative complications and length of stay (LOS).

Results

Among the 143 patients included, 50 had sarcopenia and 93 had not. Compared to the non-sarcopenia group, the sarcopenia group had a higher the incidence of PPCs (22.0% vs. 8.6%, P = 0.024). The incidence of overall postoperative complications in the sarcopenia group was higher than that in the non-sarcopenia group (36.00% vs. 20.43%, P = 0.043). There was no significant difference in the LOS between the two groups.

Conclusions

Our research indicates that sarcopenia, preoperative comorbidities, and longer duration of intraoperative oxygen saturation <95% were risk factors for PPCs. Sarcopenia is an independent risk factor for postoperative complications. Given that our results provided a correlation rather than causation, future prospective randomized trials are needed to confirm the relationship between sarcopenia and prognosis.

Association between board-certified physiatrist involvement and functional outcomes in sarcopenic dysphagia patients: a retrospective cohort study of the Japanese Sarcopenic Dysphagia Database

Objective: Dysphagia rehabilitation is an important area in geriatric nutrition due to the commonality of sarcopenic dysphagia in older adults. However, there have been no reports on the efficacy of treatment by board-certified physiatrists (BCP) in patients with sarcopenic dysphagia. This study therefore aimed to investigate whether intervention by board-certified physiatrists affects the functional prognosis of patients with sarcopenic dysphagia. Materials and Methods: Of 467 patients enrolled in the Japanese Sarcopenic Dysphagia database between November 2019 and March 2021, 433 met the study eligibility criteria. The patients were divided into two groups based on whether or not they received intervention by a BCP. The clinical characteristics and outcomes of the two groups were compared. Statistical analyses were performed by inverse probability weighting (IPW). Results: BCPs were involved in the management of 57.0% of patients with sarcopenic dysphagia. These patients had a significantly higher increase in the Barthel index both before and after IPW correction than those not managed by a BCP (P=0.001 and P=0.016, respectively). However, sarcopenic dysphagia significantly improved in the non-BCP group before IPW correction (P<0.001), although there was no significant difference after IPW correction (P=0.301). Conclusion: BCP management was significantly associated with higher activities of daily living (ADL), but not with an improvement in sarcopenic dysphagia. To provide and manage effective rehabilitation, it is necessary to familiarize patients with the management and training of sarcopenic dysphagia rehabilitation for BCP in order to cope in regions with few rehabilitation units.

The association between sarcopenia and functional outcomes in patients undergoing convalescent rehabilitation

Sarcopenia is widely believed to be linked to poorer outcomes in inpatient rehabilitation. This study aimed to assess the impact of sarcopenia on functional outcomes and dietary intake during hospitalization in adults undergoing convalescent rehabilitation. We conducted a retrospective cohort analysis at a single rehabilitation institution. The Asian Working Group Consensus Criteria for Sarcopenia was used to diagnose. The Functional Independence Measure (FIM) score was used at hospital discharge to measure the primary functional outcome. Energy and protein intakes during hospitalization were calculated as part of the nutritional assessment. There were 126 patients in the research (median age, 73 yr;54% women). Stroke (n = 73;53.4% sarcopenia) and musculoskeletal disorders (n = 53;56.6% sarcopenia) were among the admission diagnoses. Multiple linear regression analysis revealed that the FIM total score at discharge was modestly associated with sarcopenia only in stroke patients (? = 0.1872, P = 0.09), as well as significantly and independently associated with protein intake during admission only in stroke patients (? = 0.3217, P < 0.05). In hospitalized stroke patients undergoing convalescent therapy, sarcopenia is related to lower functional results. Early identification of sarcopenia and treatment with rehabilitation nutrition should be implemented in this population. J. Med. Invest. 70 : 457-463, August, 2023.

Discriminative Evaluation of Sarcopenic Dysphagia Using Handgrip Strength or Calf Circumference in Patients with Dysphagia Using the Area under the Receiver Operating Characteristic Curve

This multicenter cross-sectional study aimed to evaluate the discriminative ability of sarcopenic dysphagia (SD) using handgrip strength (HGS) or calf circumference (CC) in patients with dysphagia. Patients aged 20 years or older who were registered in a database at acute, rehabilitation, long-term care hospitals and home health care facilities were included. Logistic regression analysis was performed using SD as the outcome and HGS, CC, and other confounding factors as covariates, separately by sex. Algorithm-based SD diagnosis and HGS or CC were used as the reference and index tests, respectively. Their accuracy was evaluated using the area under the receiver operating characteristic curve (AUC), and cutoff values were calculated. Of the 460 patients, 285 (126 males) were diagnosed with SD. Logistic regression analysis showed that HGS (odds ratio [OR], 0.909; 95% confidence interval [CI], 0.873−0.947) in males and CC (OR, 0.767; 95% CI, 0.668−0.880) in females were independently associated with SD. The AUC for HGS in males was 0.735 (p < 0.001) and CC in females was 0.681 (p < 0.001). The cutoff values were 19.7 kg for HGS in males (sensitivity, 0.75; specificity, 0.63) and 29.5 cm for CC in females (sensitivity, 0.86; specificity, 0.48). HGS in males and CC in females provided statistically significant information to discriminate SD from dysphagia.

Factors Associated with Food Form in Long-Term Care Insurance Facilities

We examined factors related to dietary intake status (food form) of long-term care facility (LTCF) residents to identify factors related to proper food form choice for older individuals requiring nursing care. We surveyed 888 residents from 37 LTCFs in Japan. We evaluated basic information (age, sex, body mass index [BMI]), food form (swallowing-adjusted diet class), Barthel Index (BI), Clinical Dementia Rating (CDR), simply evaluated eating and swallowing functions, the number of present/functional teeth, oral diadochokinesis, repetitive saliva swallowing test (RSST), and modified water swallowing test. To clarify factors associated with food form, participants who had good nutrition by oral intake were categorized into the dysphagic diet (DD) and normal diet (ND) groups. Multi-level analyses were used to detect oral functions associated with food form status. Among objective assessments, BMI (odds ratio [OR] 0.979, 95% confidence interval [CI] - 0.022- to 0.006, p = 0.001), BI (OR 0.993, 95% CI - 0.007 to - 0.004, p < 0.001), CDR 3.0 (OR 1.002, 95% CI 0.002‒0.236, p = 0.046), present teeth (OR 0.993, 95% CI - 0.007 to - 0.001, p = 0.011), functional teeth (OR 0.989, 95% CI - 0.011 to - 0.005, p < 0.001), and RSST (OR 0.960, 95% CI - 0.041 to - 0.007, p = 0.006) were significantly associated with DD vs ND discrimination. Simple evaluations of coughing (OR 1.056, 0.054‒0.198, p = 0.001) and rinsing (OR 1.010, 0.010‒0.174, p = 0.029) could also discriminate food form status. These simple evaluations provide insight into the discrepancies between food form status and eating abilities of LTCF residents. Periodic evaluations by the nursing caregiver may help to prevent aspiration by older individuals with dysphagia.

Combination of High Energy Intake and Intensive Rehabilitation Is Associated with the Most Favorable Functional Recovery in Acute Stroke Patients with Sarcopenia

Energy intake and rehabilitation time individually contribute to the improvement of activities of daily living (ADL). This study aimed to investigate the additive effect of energy intake and rehabilitation time on ADL improvement in acute stroke patients with sarcopenia. The study included 140 patients (mean age 82.6 years, 67 men) with stroke. Energy intake during the first week of hospitalization was classified as “Sufficiency” or “Shortage” based on the reported cutoff value and rehabilitation time was classified as “Long” or “Short” based on the median. The study participants were categorized into four groups based on the combination of energy intake and rehabilitation time. The primary outcome was the gain of functional independence measure (FIM) motor during hospitalization. The secondary outcomes were length of stay and home discharge rates. Multivariate analysis was performed with primary/secondary outcomes as the dependent variable, and the effect of each group on the outcome was examined. Multivariate analysis showed that “long rehabilitation time and sufficient energy intake” (β = 0.391, p < 0.001) was independently associated with the gain of FIM motor items. The combination of high energy intake and sufficient rehabilitation time was associated with ADL improvement in acute stroke patients with sarcopenia.

Rehabilitation Nutrition in Patients with Chronic Kidney Disease and Cachexia

Rehabilitation nutrition is a proposed intervention strategy to improve nutritional status and physical function. However, rehabilitation nutrition in patients with cachexia and protein-energy wasting (PEW), which are the main nutrition-related problems in patients with chronic kidney disease (CKD), has not been fully clarified. Therefore, this review aimed to summarize the current evidence and interventions related to rehabilitation nutrition for cachexia and PEW in patients with CKD. CKD is a serious condition worldwide, with a significant impact on patient prognosis. In addition, CKD is easily complicated by nutrition-related problems such as cachexia and PEW owing to disease background- and treatment-related factors, which can further worsen the prognosis. Although nutritional management and exercise therapy are reportedly effective for cachexia and PEW, the effectiveness of combined nutrition and exercise interventions is less clear. In the future, rehabilitation nutrition addressing the nutritional problems associated with CKD will become more widespread as more scientific evidence accumulates. In clinical practice, early intervention in patients with CKD involving both nutrition and exercise after appropriate assessment may be necessary to improve patient outcomes.

Association of Objectively Measured Physical Activity with Physical Function in Patients with Sarcopenia during Hospitalized Rehabilitation

This study aimed to investigate the association between objectively measured physical activity and functional improvement in hospitalized patients with sarcopenia. In this retrospective cohort study, physical activity (light-intensity physical activity [LIPA]; moderate-to-physical activity [MVPA]) was measured using a triaxial accelerometer in patients with sarcopenia undergoing rehabilitation on hospital admission. The primary outcome was physical function measured with the SPPB and activity of daily living (ADL) measured with the functional independence measure scores for motor function (FIM-M) at hospital discharge. Multiple regression analysis was per-formed to investigate the relationship between the objectively measured physical activity and functional outcomes. A total of 182 patients with sarcopenia (aged 81; interquartile range (IQR) 13 years) were included in this study. In the multiple regression analysis, LIPA was associated with the SPPB score at discharge (β = 0.180, p = 0.015) but not with FIM-M at discharge. MVPA was not associated with SPPB or FIM-M scores at discharge. In conclusion, LIPA on admission is independently associated with physical function, but not ADL, in patients with sarcopenia undergoing hospitalized rehabilitation.

Impact of preoperative sarcopenia on postoperative complications and survival outcomes of patients with esophageal cancer: a meta-analysis of cohort studies

The effects of preoperative sarcopenia on postoperative complications and survival outcomes of patients undergoing esophageal cancer resection are controversial. From database establishment to 16 May 2021, we systematically searched PubMed, Embase, the Cochrane Library, Web of Science, and Chinese Biomedical Literature Database to collect relevant studies investigating the effects of preoperative sarcopenia on postoperative complications, survival outcomes, and the risk of a poor prognosis of patients undergoing esophagectomy. The Newcastle-Ottawa scale was used to evaluate the quality of the included literature, and RevMan 5.3 software was used for the meta-analysis. A total of 26 studies (3 prospective cohort studies and 23 retrospective cohort studies), involving 4,515 patients, were included. The meta-analysis showed that preoperative sarcopenia significantly increased the risk of overall complications (risk ratio [RR]: 1.15; 95% confidence interval [CI]: 1.08-1.22), pulmonary complications (RR: 1.78; 95% CI: 1.48-2.14), and anastomotic leakage (RR: 1.29; 95% CI: 1.04-1.59) and reduced the overall survival rate (hazard ratio: 1.12; 95% CI: 1.04-1.20) following esophageal cancer resection. Preoperative sarcopenia increased the risks of overall postoperative and pulmonary complications in patients undergoing esophageal cancer resection. For patients with esophageal cancer, assessing the preoperative risk of preoperative sarcopenia is necessary.

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.
