RESUMEN
Background: The effect of sarcopenia on depressive mood during geriatric rehabilitation remains unclear. This study investigated the potential influence of sarcopenia on depressive mood among geriatric patients in a rehabilitation setting. Methods: This observational cohort study enrolled 204 patients aged ≥65 years (mean: 78.8±7.6 years, 45.1% women) admitted to a rehabilitation unit between April 2020 and July 2021. Sarcopenia was diagnosed based on the Asian Working Group for Sarcopenia: 2019 Consensus Update on Sarcopenia Diagnosis and Treatment (AWGS2019) criteria, which include low handgrip strength and muscle mass. Depressive mood was defined as a 15-item Geriatric Depression Scale score of ≥6 points. We applied logistic regression models to examine the influence of sarcopenia on depressive mood at discharge. Results: We observed sarcopenia in 58.3% of patients. The logistic regression model showed that sarcopenia negatively influenced depressive mood at discharge (odds ratio, 5.460; 95% confidence interval, 2.344-13.415). Of the 68 patients without depressive mood at admission, those with sarcopenia (n=31) had a significantly higher incidence of depressive mood at discharge compared with patients without sarcopenia (n=37) (41.9% vs. 16.2%, p=0.037). Conclusion: Sarcopenia at admission negatively affected depressive mood at discharge from geriatric rehabilitation. Thus, early and routine assessment of sarcopenia is vital for patients undergoing geriatric rehabilitation.
RESUMEN
BACKGROUND & AIMS: Sarcopenia, characterized by loss of muscle mass and decreased muscle strength, significantly affects adults but also influences pediatric health. However, definitions for low muscle mass, decreased strength, and sarcopenia in children are less established, impacting interventions for improving health outcomes. The objective of this scoping review is synthesize the existing literature on the diagnostic criteria, prevalence and clinical outcomes of sarcopenia. METHODS: A scoping review, following the PRISMA extension for scoping reviews, examined pediatric sarcopenia literature until June 2023. The literature search was performed using MEDLINE and the Cochrane Central Register of Controlled Trials with the last search conducted on June 30, 2023. Criteria included studies on aged 0-20 years, covering healthy subjects, acutely ill patients, and chronic disease cases excluding specific conditions like neuromuscular diseases or prematurity. RESULTS: Initial search found 503 studies, finally, we included 56 studies. Most studies diagnosed sarcopenia using skeletal muscle mass indicators like total psoas muscle area from Computed Tomography or Magnetic Resonance Imaging. Around half of the longitudinal studies highlighted sarcopenia as a risk factor for various clinical outcomes, predominantly in hospitalized patients. However, cutoff values for sarcopenia indicators lacked consistency, with studies employing diverse percentile-based measurements or z-scores. CONCLUSION: Pediatric sarcopenia diagnosis primarily relies on skeletal muscle mass, with identified links to future clinical outcomes in specific conditions. The lack of standardized cutoffs for sarcopenia indicators underscores the necessity for age, gender, and race-specific cutoff values derived from studies establishing reference values for muscle mass and strength across diverse pediatric populations.

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

OBJECTIVE: This study aimed to clarify the effect of Type I diabetes (DIA) on transcapillary PO2 gradients, which are oxygen-driving factors between the blood and the interstitium, in the contracting muscle of rats. METHODS: Wistar male rats were divided into the diabetic (streptozocin i.p.) and sham groups. Microvascular and interstitial PO2 were measured in the extensor digitorum longus muscle during electrical stimulation-induced muscle contraction, using the phosphorescence quenching method. Transcapillary PO2 gradient, ΔPO2, was calculated as microvascular minus interstitial PO2. RESULTS: Resting microvascular PO2 was higher in the diabetic group than in the sham group (6.3 ± 1.7 vs. 4.7 ± 0.9 mmHg, p < 0.05) and remained for 180 s. Interstitial PO2 from rest to muscle contraction did not differ between the groups. The ΔPO2 was higher in the diabetic group than in the sham group at rest and during muscle contraction (4.03 ± 1.42 vs. 2.46 ± 0.90 mmHg at rest; 3.67 ± 1.51 vs. 2.22 ± 0.65 mmHg during muscle contraction, p < 0.05). Marked muscle atrophy was observed in the diabetic group. CONCLUSION: DIA increased microvascular and transcapillary PO2 gradients in the skeletal muscle. The enhanced PO2 gradients were maintained from rest to muscle contraction in diabetic muscle.

BACKGROUND & AIMS: Pulmonary tuberculosis is a severe disease with a high mortality rate. However, whether sarcopenia is a risk factor for in-hospital mortality remains unclear. The SARC-F (five items: strength, assistance in walking, rising from a chair, climbing stairs, and falls) is a questionnaire developed to screen for sarcopenia. This study aimed to determine whether the high risk of sarcopenia, assessed using the SARC-F questionnaire, affects in-hospital mortality in older patients with pulmonary tuberculosis. METHODS: This was a retrospective, observational study. We included patients with active pulmonary tuberculosis aged ≥65 years who required inpatient treatment between 30 April 2021 and 30 November 2022. We assessed sarcopenia using SARC-F, and SARC-F ≥ 4 points at admission was defined as a high risk of sarcopenia. The primary outcome was all-cause mortality during hospitalisation. We extracted information on age, sex, body mass index, comorbidities, blood and biochemical tests, modified Glasgow Prognostic Score, calf circumference, geriatric nutritional risk index, physiotherapy, and length of hospital stay from medical records. RESULTS: We included 147 patients (mean age: 83.0 ± 7.8 years; males: 61.9%). Ninety-three (63.3%) patients had a high risk of developing sarcopenia. Patients with a high risk of sarcopenia were significantly older (mean: 85.0 ± 7.1 years), had a lower body mass index (median: 18.1 kg/m2, range: 16.1-20.5 kg/m2), had a higher modified Glasgow Prognostic Score (median: 2, range: 2-2), and had a lower calf circumference (mean: 26.8 ± 3.6 cm), had a lower geriatric nutritional risk index (mean: 72.2 ± 12.9) than those without high-risk sarcopenia. More patients with a high risk of sarcopenia underwent physiotherapy (93.5%) than those without high-risk sarcopenia (P < 0.01, all). Kaplan-Meier survival curves showed that patients with a high risk of sarcopenia had significantly lower overall survival than those without high-risk sarcopenia (log-rank test, P = 0.001). Logistic regression analysis for in-hospital mortality showed that a high risk of sarcopenia significantly affected in-hospital mortality (odds ratio [OR]: 6.425, 95% confidence interval [CI]: 1.399-47.299). In addition, logistic regression analysis for each item of SARC-F showed that assistance in walking (OR: 3.931, 95% CI: 1.816-9.617) and rising from a chair (OR: 2.458, 95% CI: 1.235-5.330) significantly affected in-hospital mortality. CONCLUSION: A high risk of sarcopenia, as assessed using SARC-F at admission, was a risk factor for in-hospital mortality in older patients with pulmonary tuberculosis. Among the SARC-F items, assistance in walking and rising from a chair were the risk factors for in-hospital mortality.

BACKGROUND: The association of the combination of body mass index (BMI) and weight change at admission with prognoses in patients with heart failure (HF) is unclear. Therefore, we investigated whether BMI and weight changes at admission affect mortality in patients with HF. METHODS: This retrospective cohort study lasted 99 months, starting in April 2014, and included 4,862 patients with HF from a Japanese real-world database. Cubic and thin-plate smoothing spline analyses were performed to investigate the association of BMI and weight changes with mortality. The percentage weight change was calculated every 6 months. The study outcome was the presence or absence of death. RESULTS: The patients' mean age was 81.5±9.6 years, and 1,239 (25.5%) patients died. Cubic spline analysis revealed a negative correlation of BMI with mortality hazard ratio (HR) (BMI of 18.5 kg/m2 and 25 kg/m2; HR=1.3 [1.2-1.4] and 0.8 [0.7-0.9], respectively). Cubic spline analysis of weight change showed that weight loss tended to increase the mortality HR (each 6% decrease in weight change rate was associated with a 1.1 times higher mortality risk (95% CI [1.0-1.2]) Thin-plate smoothing spline analysis showed that the odds ratio (OR) negatively correlated with BMI (1-year mortality: BMI of 18.5 kg/m2, 22 kg/m2, and 25 kg/m2; OR at 0% weight change=1.5, 1.0, and 0.7, respectively; 2-year mortality: BMI=18.5 kg/m2, 22 kg/m2, and 25 kg/m2; OR at 0% weight change=1.4, 0.9, and 0.7, respectively). CONCLUSION: A low BMI in patients with HF was associated with a higher risk of mortality. Weight loss in patients, regardless of BMI, was associated with a higher OR for mortality.

BACKGROUND: The modified Rankin scale (mRS) is extensively used for premorbid evaluation in patients with stroke; however, its limited capacity to assess functional status highlights the need for additional indicators such as frailty. AIMS: This study aimed to assess the impact of the premorbid mRS score and frailty on daily living (ADL) activities at hospital discharge, focusing on varying stroke severities. METHODS: This single-centre, prospective cohort study included patients with acute stroke aged ≥60 years. Key metrics included the frailty index for frailty assessment or mRS for functional status premorbid and the functional independence measure of the motor domain (FIM-M) at discharge for ADL outcomes. The patients were categorized into mild (0-4), moderate (5-15), and severe (16-42) groups based on the National Institute of Health Stroke Scale. Multiple hierarchical linear regression analyses were performed for each group to evaluate the influence of mRS and frailty on FIM-M scores. RESULTS: In the mild stroke group, significant associations were observed with premorbid mRS3 (ß = -0.183, p = 0.004), mRS4 (ß = -0.234, p < 0.001), and frailty status (ß = -0.227, p = 0.005) and FIM-M scores. Premorbid frailty did not show a significant association with the FIM-M scores in the moderate or severe stroke group. Frailty status notably contributed to changes in R², particularly in the mild stroke group (R² change = 0.031, p = 0.002). However, such changes were not evident in the other stroke severity groups. CONCLUSION: This study emphasizes the importance of incorporating frailty assessments into premorbid evaluations, particularly when considering ADL outcomes in patients with mild stroke. Conversely, the significance of frailty in moderate-to-severe stroke was less evident.

PURPOSE: Frailty and hospitalization-associated disabilities (HAD) are geriatric conditions that should be managed in older patients undergoing pancreatectomy. The Hospital Frailty Risk Score (HFRS) can evaluate frailty based on medical records and could predict postoperative activities of daily living (ADL) decline. This study aimed to investigate whether HFRS affects the postoperative incidence of HAD in older patients who underwent pancreatectomy. METHODS: This retrospective, observational study used data from a nationwide hospital-based database. We included consecutive patients aged ≥ 65 years who were diagnosed with pancreatic cancer (International Statistical Classification of Diseases, 10th revision code C25) and underwent curative pancreatectomy between April 2014 and August 2020. We evaluated preoperative frailty using HFRS. The primary outcome was HAD following pancreatectomy. Logistic regression analysis was performed for analyzing the impact of frailty on HAD following pancreatectomy. RESULTS: We included 671 patients for the analysis (mean age 74.3 ± 5.6, male 54.8%). The prevalence of intermediate and high risk of frailty with HFRS ≥ 5 was 2.7%. The incidence of HAD was significantly higher in the intermediate- and high-risk groups compared to that in the low-risk group (33.3% vs. 8.4%, p < 0.001). Logistic regression analysis demonstrated that intermediate and high risks of frailty increased the likelihood of HAD (odds ratio, 3.55; 95% confidence interval: 1.12-11.2). CONCLUSIONS: The risk of frailty evaluated using the HFRS increased the likelihood of developing HAD in older patients undergoing pancreatectomy. Future research on effective perioperative interventions for preventing postoperative HAD and enhancing postoperative ADL recovery is warranted.
RESUMEN
AIM: How possible sarcopenia affects functional prognosis in patients with premorbid disability remains unclear. This study aimed to compare and investigate the impact of possible sarcopenia at admission on functional outcomes at discharge in patients with acute stroke with and without premorbid disability. METHODS: This cohort study enrolled patients who were consecutively admitted to a single center for acute stroke. Calf circumference and grip strength were measured within 7 days of admission, and possible sarcopenia was determined using the Asian Working Group for Sarcopenia 2019 criteria. The Functional Independence Measure (FIM) score at discharge during the acute phase was the primary outcome. To examine the impact of possible sarcopenia on FIM scores at discharge, patients were divided into two groups according to being with or without premorbid disability according to the modified Rankin Scale, and multiple linear regression analysis was performed in each group. RESULTS: This study included 456 patients with acute stroke (median age, 80 years). In the premorbid-disability group (n = 166), possible sarcopenia was present in 140 patients (84%). Patients without possible sarcopenia had significantly higher FIM scores at discharge compared with those with possible sarcopenia (P < 0.001). However, multiple linear regression analysis showed that possible sarcopenia was not associated with FIM scores at discharge in the premorbid-disability group (ß = -0.054, P = 0.346). CONCLUSIONS: The results of this study demonstrated that a high rate of possible sarcopenia was observed in patients with stroke with premorbid disability; however, this did not affect functional prognosis.

BACKGROUND & AIMS: Nutritional status is a significant issue in an aging society; however, the impact of the nutritional status of older individuals using long-term care services on the caregiving burden remains unclear. This systematic review and meta-analysis aimed to investigate the impact of nutritional issues on adverse outcomes in older individuals using long-term care services. METHODS: We used data from the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Web of Science, CINAHL, and Ichu-shi Web databases. Original articles published in English or Japanese between January 2000 and July 2022 were included. The inclusion criteria were interventional and observational studies on individuals using long-term care services with aged ≥65 years and a focus on body weight or weight loss. Data on adverse outcomes related to caregiving burden, including the number of people requiring care, mortality, complications, activities of daily living (ADL), and quality of life, were collected. RESULTS: The literature search yielded 7873 studies, of which 35 were ultimately included. Seven observational studies investigated mortality outcomes, and seven examined ADL outcomes. The meta-analysis revealed significantly higher mortality rates in individuals classified as underweight (BMI <18.5 kg/m2) than in those with BMI ≥18.5 kg/m2 (risk ratio [RR] 1.49; 95 % confidence interval [CI] 1.31 to 1.73, 0.22; I2 93 %). Further, on categorising the participants based on a BMI cutoff of 25 kg/m2, those with a BMI of <25 kg/m2 had a significantly increased mortality rate (RR 1.21; 95 % CI 1.04-1.40; I2 = 98 %). BMI and weight loss did not affect ADL. CONCLUSIONS: Our findings indicate that underweight and weight loss are significantly associated with increased mortality in older individuals using long-term care services. Therefore, appropriate weight management is recommended for this population. However, further research is necessary owing to the high heterogeneity observed in this study.

OBJECTIVE: This study aims to examine the effect of sepsis on the dynamics of skeletal muscle partial oxygen pressure during muscle contractions as well as the effect of reactive oxygen species (ROS) scavenger (ascorbic acid, Asc). METHODS: Twenty-seven male Sprague-Dawley rats (2-3 months old) were randomly assigned to three groups; sham, cecal ligation and puncture (CLP), or CLP plus ascorbic acid treatment group (CLP + Asc). Electrical stimuli-induced muscle contractions and partial oxygen pressure measurements were performed at 3 h after CLP. The interstitial oxygen pressure (PO2 is) in the spinotrapezius muscle was measured by the phosphorescence quenching method. RESULTS: The PO2 is at rest was not different between the three groups. The PO2 is decreased from rest to contraction in all groups. Compared to the sham, the time to decrease PO2 is was significantly faster in CLP but not in CLP + Asc (p < .05). Compared to the sham, the PO2 is during muscle contractions was significantly lower in both CLP and CLP + Asc (p < .05, respectively). CONCLUSIONS: Our results suggest that CLP-induced sepsis accelerated the decay of PO2 is at the onset of muscle contractions and maintained a low level of PO2 is during muscle contractions.

OBJECTIVES: Oropharyngeal dysphagia is one of the most prevalent health complications in older adults. The prevalence of postoperative dysphagia is expected to rise with the increasing number of older patients undergoing orthopedic surgery; however, the specific prevalence and contributing factors remain unclear. This scoping review aimed to identify the prevalence and factors related to postoperative dysphagia in older orthopedic patients. METHODS: This review included studies published up to September 2022 on postoperative patients aged ≥ 60 years who underwent orthopedic surgery. We searched MEDLINE, EMBASE, CINAHL, CENTRAL, Web of Science, and Ichushi-Web. RESULTS: In total, 21 of the 2158 identified studies were reviewed. The studies were classified into the three categories according to the surgical site: cervical spine disease (n = 12), hip fracture (n = 7), and others (n = 2). The estimated dysphagia prevalence rates [95 % confidence interval] of cervical spine disease, hip fractures, and others were 16 % [8-27], 32 % [15-54], and 6 % [4-8], respectively. Factors related to postoperative dysphagia included cervical alignment in cervical spine disease, being older within the cohort, preoperative health status, malnutrition, and sarcopenia in hip fractures. CONCLUSIONS: The prevalence of postoperative dysphagia after orthopedic surgery was highest for hip fractures, followed by cervical spine and others. These results suggest non-neurogenic dysphagia in older patients undergoing orthopedic surgery and indicate that sarcopenia may contribute to postoperative dysphagia in this population. Therefore, further research should clarify the trajectory of postoperative dysphagia and the effectiveness of rehabilitation for postoperative dysphagia after orthopedic surgery.

The aim of this scoping review was to characterize the diagnostic criteria, their cutoff values, and the prevalence of cachexia in Asians. We systematically reviewed studies involving Asian adult patients with cachexia due to cancer and chronic diseases other than cancer, such as heart and renal failure. Sources in English and Japanese published between December 2008 and April 2022, including observational, longitudinal, cross-sectional, and clinical trials, were examined. We searched six databases. Altogether, 4131 studies were screened, and 107 eligible articles were identified, of which 11 and 96 were conducted on non-cancer and cancer patients, respectively. The most common clinical indicators used for diagnosis were weight loss, body mass index (BMI), and muscle mass. The most frequently employed diagnostic criteria for cachexia in non-cancer patients were the modified/excerpt Evans criteria. Contrarily, the original Fearon's criteria were often used in patients with cancer. Additionally, cutoff values for BMI and muscle mass affected by racial anthropometric differences were investigated. The mean or median value of BMI ranges were 18.3 to 25.2 and 17.5 to 25 kg/m2 for non-cancer and cancer patients, respectively. The prevalence rates of cachexia were 3.4% to 66.2% and 6.2% to 93% in non-cancer and cancer patients, respectively. Several diagnostic criteria, such as BMI and muscle mass, have been used, which are affected by racial differences in body size. However, few studies have used cutoff values for Asians.

OBJECTIVES: This study aimed to investigate body mass index (BMI) and rate of weight change associated with adverse outcomes in Asian patients with chronic kidney disease. METHODS: A retrospective cohort study was performed between April 2014 and June 2022 using the administrative claims database compiled by the Japan Medical Data Center. Patients were defined as individuals with comorbidities with chronic kidney disease stages 3 to 5 on admission and were aged ≥40 y with BMI at admission and BMI information from a previous admission 3 to 12 mo earlier. Restricted cubic spline analysis and thin-plate smoothed spline analysis were performed. RESULTS: A total of 10 802 individuals were analyzed. The mean age was 74.6 ± 11.3 y, number of men was 7175 (66.4%), and 2115 (19.6%) deaths were recorded. Smoothed splines for BMI found that low BMI was associated with high hazard ratio (HR) (BMI = 18.5 kg/m2; HR = 1.3 [1.2-1.4]). Smoothed splines of weight change found higher HR with increasing rate of weight change for both weight gain and loss (weight change rate = -10%; HR = 1.4 [1.3-1.5]; weight change rate = 10%; HR = 1.2 [1.1-1.3]). In thin-plate smoothed spline analysis, the U-curve had a higher odds ratio as BMI decreased in patients with or without dialysis and as the degree of weight change increased. CONCLUSIONS: We found trends in BMI and rate of weight change associated with mortality in Asian patients with chronic kidney disease.

OBJECTIVE: Conventional diagnostic criteria for cachexia are based on Western studies. The aim of this study was to investigate trends in body mass index (BMI) and the rate of weight change associated with adverse outcomes in Asian patients with advanced cancer. METHODS: This retrospective cohort study was conducted using the administrative claims database compiled by the Japan Medical Data Center Inc. The study was conducted between April 2014 and September 2022 on patients with advanced cancer. A Cox regression model was used to perform a restricted cubic spline analysis with four knots for BMI and weight change. Additionally, thin-plate smoothed splines were used to generate contour plots of the odds ratios of BMI and weight change for mortality. RESULTS: The study analyzed 48 600 patients. The mean age was 71.9 ± 10 y. There were 33 051 men (68%) and 17 853 deaths (37%). The smoothed splines for BMI showed that low BMI was associated with high hazard ratio (HR, [95% confidence interval]; BMI = 18.5 kg/m2, HR, 1.2; [1.1-1.2]; BMI = 25 kg/m2, HR, 0.9; [0.9-0.9]). The smoothed spline of weight change showed a higher HR with an increasing rate of weight change (weight change rate -10%, HR, 1.1; [1.1-1.2]; weight change rate +10%, HR, 1; [1-1]). In the thin-plate smoothed spline analysis, patients with BMI <17 to 18.5 kg/m2 were at a higher risk for death regardless of weight change. CONCLUSIONS: Low BMI, a large degree of weight change, or a combination of both, predicted death in Asian patients with advanced cancer.
RESUMEN
BACKGROUND & AIMS: Sarcopenic obesity (SO) is associated with worse outcomes in patients with colorectal cancer (CRC); however, the diagnostic methods and prevalence of SO vary among studies. Therefore, we conducted this scoping review to investigate the diagnosis of SO in CRC, identify the associated problems, and determine its prevalence. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews reporting guidelines. A literature search was performed by two independent reviewers on studies that diagnosed SO in CRC using the MEDLINE, EMBASE, CINAHL, CENTRAL, Web of Science, and Ichushi-Web (in Japanese) databases. Observational, longitudinal, cross-sectional, and clinical trials written in English or Japanese as of July 2022 were included. Studies that did not define SO were excluded from the analysis. The study protocol was pre-registered in Figshare. RESULTS: In total, 670 studies were identified, 22 of which were included. Eighteen studies used sarcopenia in combination with obesity to diagnose SO. Sarcopenia was mainly diagnosed using skeletal muscle mass index (SMI), and only one combined with grip strength or gait speed. Obesity was diagnosed based on the body mass index (BMI; n = 11), followed by visceral fat area (VFA; n = 5). The overall prevalence of SO in patients with CRC was 15% (95%CI, 11-21%). The prevalence of SO in surgical resection and colorectal cancer liver metastases was 18% (95%CI, 12-25%) and 11% (95%CI, 3-36%), respectively. CONCLUSIONS: SO in patients with CRC was mainly diagnosed based on a combination of SMI and BMI, and muscle strength and body composition were rarely evaluated. The prevalence of SO was approximately 15%, depending on the diagnostic methods used. Since SO in patients with CRC is associated with poor prognosis, further research on diagnostic methods for the early detection of SO and its clinical outcomes is needed.

OBJECTIVES: The aim of this study was to determine the effects of malnutrition on trunk function and lower leg muscle strength in patients with acute stroke upon hospitalization. METHODS: This prospective cohort study included hospitalized patients with acute stroke. Nutritional status was assessed using the Global Leadership Initiative on Malnutrition criteria. Trunk function and lower leg muscle strength were assessed using the trunk control test (TCT) and Motricity Index (MI), respectively, on admission and at discharge. Logistic regression analysis was performed to examine the relationship between malnutrition and poor improvement in TCT and MI scores at discharge. RESULTS: Patients (N = 241) with acute stroke (median age 79 y) were included in this study. In adjusted logistic regression analysis, malnutrition was independently associated with poor TCT score improvement (adjusted odds ratio, 3.82; 95% confidence interval, 1.11-13.20; P = 0.03). In contrast, malnutrition was not independently associated with poor MI score improvement (adjusted odds ratio, 0.86; 95% confidence interval, 0.30-2.52; P = 0.79). CONCLUSION: Malnutrition on admission leads to poor trunk function, but not lower leg muscle strength, in patients with acute stroke.

PURPOSE: Physical activity is important to improve recovery following surgery. This study investigated the impact of physical activity on the development of pneumonia after radical esophagectomy in patients with thoracic esophageal cancer in the subacute phase from postoperative day 11 to hospital discharge. METHODS: This retrospective cohort study included 83 patients who underwent radical esophagectomy for esophageal cancer between 2016 and 2022. Physical activity was measured using an activity tracker, and the average number of steps between postoperative days 8 and 10 was examined. The primary outcome was pneumonia (Clavien-Dindo classification 2 or higher) developing between postoperative day 11 and hospital discharge. We used the receiver operating characteristic (ROC) curve analysis to calculate the optimal cutoff value of physical activity that can predict the development of pneumonia and define low physical activity. We used logistic regression analysis to investigate the impact of low physical activity on postoperative pneumonia. RESULTS: Pneumonia developed in 10 patients (12.0%) during the observation period. The optimal cutoff value of physical activity for predicting pneumonia was 1494 steps per day (sensitivity: 60.0%, specificity: 89.0%, area under the curve: 0.743). In multivariate analysis, low physical activity was an independent predictor of incident pneumonia [odds ratio: 12.10, 95% confidence interval: 2.21-65.90, p = 0.004], with adjustment for age, gastric tube reconstruction route, and postoperative recurrent nerve palsy. CONCLUSIONS: Physical activity following radical esophagectomy in patients with thoracic esophageal cancer was an independent predictor of the development of pneumonia in the subacute phase after radical esophagectomy.

Osteosarcopenia is a new definitional approach that can increase the risk of falls and fractures in elderly compared with that of osteoporosis and sarcopenia alone. However, biomarkers for osteosarcopenia have not been well identified. Thus, we aimed to explore the biomarkers of osteosarcopenia, including bone, muscle, and geriatric markers. Outpatients attending a frailty clinic were enrolled in the study. Osteosarcopenia was defined as the coexistence of osteoporosis and sarcopenia. Osteoporosis was defined according to the criteria of the Japan Osteoporosis Society. Sarcopenia was defined according to the Asian Working Group for Sarcopenia consensus (2019). We selected 35 blood/serum pathological parameters, including bone, inflammation, nutritional, and aging markers for the study. Logistic regression analysis for osteosarcopenia was performed to explore the biomarkers of osteosarcopenia. Of the total 600 patients with a mean age of 76.6 years, 595 were enrolled in the registry during the study period. Logistic regression analysis for osteosarcopenia showed that elevated thyroid-stimulating hormone (TSH) (odds ratio [OR]:1.375; 95 % confidence interval [CI]: 1.092-1.731), bone-specific alkaline phosphatase (BAP) (OR: 1.059; 95 % CI: 1.002-1.120), and estimated glomerular filtration rate (eGFR) (OR: 1.029; 95 % CI: 1.007-1.053) increased the likelihood of osteosarcopenia. On the other hand, elevated 25-hydroxyvitamin D (25OHD) (OR: 0.905; 95 % CI: 0.841-0.974), blood urea nitrogen (BUN) (OR: 0.895; 95 % CI: 0.829-0.966) and K (OR: 0.241; 95 % CI: 0.081-0.717) decreased the likelihood of osteosarcopenia. It is worthwhile to examine these biomarkers for older adult outpatients attending a frailty clinic for screening osteosarcopenia. Further studies are needed to investigate the effects of other markers of bone metabolism.
