Abstract
BACKGROUND AND PURPOSE Prior observational studies have suggested a strong correlation between sarcopenia and stroke, but the causal link between them remains uncertain. This study aims to investigate the associations between genetically predicted sarcopenia-related traits and stroke using a two-step Mendelian randomization (MR) approach. METHODS Genome-wide association study (GWAS) summary data for sarcopenia-related traits were acquired from the UK Biobank. Genetic associations for ischemic stroke (IS) and its subtypes were selected from the MEGASTROKE consortium comprising European ancestry participants. GWAS summary data for cerebral hemorrhage were obtained from the FinnGen consortium, including intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). MR estimates were calculated using the inverse-variance weighted (IVW) method. The robustness of results was assessed for heterogeneity and pleiotropy of individual single nucleotide polymorphisms (SNPs). RESULTS Higher appendicular lean mass (ALM) exhibited a potential causal association with a reduced incidence of large artery atherosclerosis (LAA) (odds ratio [OR] = 0.81, 95% confidence interval [CI]:0.71-0.93; P = 0.003) and small vessel disease (SVD) (OR = 0.83, 95% CI:0.74-0.94; P = 0.002). The associations of ALM with IS and ICH were compromised after adjusting for body fat and physical activity with multivariable MR. Two-step MR mediation analysis explored 33 candidate mediators, among which hypertension and SBP accounted for more than 10% of the mediation proportion in the relationship between ALM and stroke and its subtypes. CONCLUSION Our research findings indicate that lower ALM is associated with a increased risk of stroke . It is necessary to explore the specific protective mechanisms of higher ALM for preventing stroke occurrence.

[PMID: 38762444 PMCID: PMC11102192 DOI: 10.1186/s12877-024-05039-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 05/02/2024] [Indexed: 05/20/2024] Open
Abstract
BACKGROUND Appendicular lean mass (ALM) is a good predictive biomarker for sarcopenia. And previous studies have reported the association between ALM and stroke or Alzheimer's disease (AD), however, the causal relationship is still unclear, The purpose of this study was to evaluate whether genetically predicted ALM is causally associated with the risk of stroke and AD by performing Mendelian randomization (MR) analyses. METHODS A two-sample MR study was designed. Genetic variants associated with the ALM were obtained from a large genome-wide association study (GWAS) and utilized as instrumental variables (IVs). Summary-level data for stroke and AD were generated from the corresponding GWASs. We used random-effect inverse-variance weighted (IVW) as the main method for estimating causal effects, complemented by several sensitivity analyses, including the weighted median, MR-Egger, and MR-pleiotropy residual sum and outlier (MR-PRESSO) methods. Multivariable analysis was further conducted to adjust for confounding factors, including body mass index (BMI), type 2 diabetes mellitus (T2DM), low density lipoprotein-C (LDL-C), and atrial fibrillation (AF). RESULTS The present MR study indicated significant inverse associations of genetically predicted ALM with any ischemic stroke ([AIS], odds ratio [OR], 0.93; 95% confidence interval [CI], 0.89-0.97; P = 0.002) and AD (OR, 090; 95% CI 0.85-0.96; P = 0.001). Regarding the subtypes of AIS, genetically predicted ALM was related to the risk of large artery stroke ([LAS], OR, 0.86; 95% CI 0.77-0.95; P = 0.005) and small vessel stroke ([SVS], OR, 0.80; 95% CI 0.73-0.89; P < 0.001). Regarding multivariable MR analysis, ALM retained the stable effect on AIS when adjusting for BMI, LDL-C, and AF, while a suggestive association was observed after adjusting for T2DM. And the estimated effect of ALM on LAS was significant after adjustment for BMI and AF, while a suggestive association was found after adjusting for T2DM and LDL-C. Besides, the estimated effects of ALM were still significant on SVS and AD after adjustment for BMI, T2DM, LDL-C, and AF. CONCLUSIONS The two-sample MR analysis indicated that genetically predicted ALM was negatively related to AIS and AD. And the subgroup analysis of AIS revealed a negative causal effect of genetically predicted ALM on LAS or SVS. Future studies are required to further investigate the underlying mechanisms.

Abstract
Stroke triggers a systemic inflammatory response over the ensuing days after the cerebral insult. The age and comorbidities of the stroke population make them a vulnerable population for low muscle mass and sarcopenia, the latter being another clinical condition that is closely associated with inflammation, as shown by increased levels of pro-inflammatory biomarkers, including neutrophil-to-lymphocyte ratio (NLR). In this study, we evaluated the relationship between post-stroke NLR changes and muscle mass in a prospective cohort of acute ischemic stroke patients (n = 102) enrolled in the Muscle Assessment in Stroke Study Turkey (MASS-TR). Admission lumbar computed tomography images were used to determine the cross-sectional muscle area of skeletal muscles at L3 vertebra level and calculate the skeletal muscle index (SMI). The median (IQR) SMI was 44.7 (39.1-52.5) cm2/m2, and the NLR at admission and follow-up were 4.2 (3.0-10.5) and 9.4 (5.7-16.2), respectively. While there was no relationship between SMI and admission NLR, a significant inverse correlation was observed between SMI and follow-up NLR (r = - 0.26; P = 0.007). Lower SMI remained significantly associated (P = 0.036) with higher follow-up NLR levels in multivariate analysis. Our findings highlight the importance of muscle mass as a novel factor related to the level of post-stroke stress response.

Abstract
INTRODUCTION Sarcopenia associated with stroke can significantly impact patient prognosis; however, the current standard diagnostic methods for sarcopenia are rarely used in stroke patients. Therefore, the aim of the current study was to investigate whether the temporal muscle thickness (TMT) or area (TMA) could serve as a surrogate marker for measuring skeletal muscle mass. METHODS This retrospective chart review study was conducted on 244 participants from March 2018 to February 2020. The TMT and TMA were measured at the supraorbital roof level using brain CT or T1-weighted MR imaging obtained from participants. The skeletal muscle mass and skeletal muscle index (SMI) and whole-body phase angle (WBPA) at 50 kHz were collected. Pearson correlation analysis was used to assess the relationship between the TMT or TMA and the results of the bioimpedance analysis. RESULTS The mean TMT showed significant positive correlations with skeletal muscle mass (male, r = 0.520; female, r = 0.706), SMI (male, r = 0.426; female, r = 0.582), and WBPA (male, r = 0.295; female, r = 0.232). The mean TMA showed significant positive correlations with skeletal muscle mass (male, r = 0.490; female, r = 0.657), SMI (male, r = 0.289; female, r = 0.473), and WBPA (male, r = 0.232; female, r = 0.243). CONCLUSION We observed moderate to strong positive correlations between body composition analysis measured by BIA and TMT or TMA, suggesting that TMT or TMA could serve as a reliable surrogate marker for identifying low skeletal muscle mass in cerebrovascular disease.

Abstract
This study aimed to investigate the association between muscle mass deficit and the initial severity of ischemic stroke. The impact of muscle mass deficit on the discharge outcome was also evaluated. This retrospective study included 660 patients with acute ischemic stroke who underwent bioelectrical impedance analyses. We compared the National Institute of Health Stroke Scale (NIHSS) score, occurrence of moderate stroke (NIHSSS ≥ 5) at admission, and unfavorable functional outcome (modified Rankin Scale score ≥ 2) at discharge between patients with and without muscle mass deficit using Poisson and logistic regression analyses. The mean age of the study patients was 65.6 ± 13.0, and 63.3% were males. Muscle mass deficit was present in 24.4% of patients. Muscle mass deficit was significantly and independently associated with NIHSS score or moderate stroke (all p < 0.05). This association was noted regardless of patient characteristics. Among the respective NIHSS items, muscle mass deficit was significantly associated with facial palsy, motor function of the arm or leg, limb ataxia, and dysarthria. Muscle mass deficit also led to unfavorable functional outcome, which was mediated by the initial NIHSS score. In conclusion, muscle mass deficit is associated with higher NIHSS score and unfavorable functional outcome in patients with acute ischemic stroke.

Abstract
BACKGROUND & AIMS This study aimed to investigate the associations of pre-existing sarcopenia with swallowing function, oral intake level, and aspiration pneumonia in patients with acute stroke. METHODS This observational study included patients (≥60 years of age) with acute ischemic stroke or intracerebral hemorrhage within 7 days of onset who were screened for sarcopenia, malnutrition, and swallowing difficulties in a stroke-care unit within 48 h of admission. Sarcopenia was defined by the Asian Working Group on Sarcopenia 2019 as having a low calf circumference, handgrip strength, and appendicular muscle mass index. The primary outcome was impaired oral intake (functional oral intake scale <5 points) at 3, 7, and 14 days after admission, and the secondary outcome was aspiration pneumonia during hospitalization. RESULTS We enrolled 350 patients (median age of 77 years; 63% males) who underwent the aforementioned screening. Sarcopenia was diagnosed in 34% of patients, and malnutrition was found in 66% of patients with sarcopenia. When compared with the comparison group (defined as patients with either or both normal calf circumference and handgrip strength), the sarcopenia group had significantly lower tongue pressure and a higher prevalence of dysphagia. Sarcopenia was associated with functional oral intake scale <5 at 7 days (adjusted odds ratio [OR], 4.72; 95% confidence interval [CI], 1.91-11.71); p = 0.002) and 14 days (adjusted OR, 3.93; 95% CI, 1.47-10.53; p = 0.006) and with aspiration pneumonia during hospitalization (adjusted OR, 6.12; 95% CI, 1.63-22.94; p = 0.007). CONCLUSION Acute stroke patients with sarcopenia may have weakness of the swallowing-related muscles which may lead to impaired oral intake and aspiration pneumonia.

Abstract
PURPOSE Post-stroke dysphagia (PSD) is a common sequela of stroke. Given the association between dysphagia and sarcopenia, we aimed to investigate the association between PSD and temporal muscle thickness (TMT) and masseter muscle thickness (MMT) following endovascular thrombectomy (EVT) in patients with large-vessel occlusion (LVO). METHODS This retrospective cohort study included hospitalized patients with LVO stroke who underwent EVT between January 1, 2018, and October 31, 2022. TMT and MMT were measured using brain computed tomography (CT) angiography. The correlation between relevant clinicodemographic factors and both TMT and MMT was examined. The relationship between each of two parameters (TMT and MMT) and PSD, which was defined as the retention of the nasogastric (NG) tube at 4 and 12 weeks, was evaluated in adjusted logistic regression models. RESULTS Among the 148 participants, the mean TMT and MMT was 5.9 ± 1.6 and 11.2 ± 2.3 mm, respectively. Lower age, male sex, higher body mass index (BMI), higher albumin levels, and a lower initial National Institute of Health Stroke Scale (NIHSS) score were associated with higher TMT and MMT (p < 0.05). In the logistic regression analysis adjusted for age, sex, BMI, serum albumin, and NIHSS score, lower TMT and MMT significantly correlated with PSD at weeks 4 and 12 (p < 0.001). CONCLUSION TMT and MMT are associated with age, sex, BMI, albumin, and the initial NIHSS score. Both TMT and MMT are independent indicators of post-EVT PSD in stroke patients and serve as reliable predictors of NG removal.

Abstract
INTRODUCTION Changes in skeletal muscle mass affect physical performance in chronic stroke survivors. The skeletal muscle mass index is thus an important assessment factor in stroke; however, its value in the acute phase is unclear. OBJECTIVE This study investigated the association between skeletal muscle mass and acute stroke outcome. DESIGN This was a single-center cohort study design. PARTICIPANTS A total of 189 consecutively hospitalized patients with acute stroke were included in the study. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The main outcome of the study was a good modified Rankin Scale (mRS) score at hospital discharge. We divided the participants into good (mRS score 0-2) and poor (mRS score 3-6) function groups. Logistic regression was performed to identify the factors associated with functional prognosis. RESULTS Atrial fibrillation (odds ratio [OR], 14.95; 95% confidence interval [CI], 2.45-91.39; P = 0.003), pre-mRS (OR, 2.22; 95% CI, 1.05-4.68; P = 0.036), National Institutes of Health Stroke Scale (OR, 1.32; 95% CI, 01.12-1.56; P = 0.001), skeletal muscle mass index (OR, 0.31; 95% CI, 0.11-0.87; P = 0.027), and Lower Extremity Fugl-Meyer Assessment (OR, 0.68; 95% CI, 0.56-0.82; P = 0.000) were all independently associated with the functional prognosis of the patients included in the study. CONCLUSION This study confirmed that skeletal muscle mass is a strong prognostic factor in acute stroke. Thus, prestroke skeletal muscle mass, along with stroke severity and lower limb paralysis, needs to be assessed to more accurately determine the prognosis of patients with stroke.

Abstract
BACKGROUND AND PURPOSE Poor clinical outcomes are still common in successfully reperfused acute ischemic stroke patients. The aim of our study was to assess the impact of sarcopenia and myosteatosis on neurological outcomes and mortality in successfully reperfused acute ischemic stroke patients. MATERIALS AND METHODS We included in our retrospective observational study 166 consecutive patients who underwent technically successful mechanical thrombectomy for anterior circulation acute ischemic stroke between Jan 2016 and Dec 2019. ASPECTS and collateral score were assessed on pre-operative CT/CTA. Masseter muscles area and attenuation were measured on CTA images. Clinical and radiological variables were tested in multivariate logistic models to predict the probability of death and, among survivors, of incurring poor outcome. RESULTS At admission, mean NIHSS was 19 (SD = 6.5), mean body mass index 25.5 (SD = 4.4) kg/m2, and mean ASPECTS 8.0 (SD = 1.9). Of all, 48.2% patients showed good collaterals, 38.5% intermediate collaterals, and 13.3% poor collaterals. Overall, 90 days mRS was ≤2 in 48.2% of the patients, 3-5 in 30.7%, and 6 in 21.1%. At multivariate logistic regression, age (OR = 1.08, p = 0.036), ASPECTS (OR = 0.59, p = 0.013), and masseter muscles attenuation (OR = 0.93, p = 0.010) were independent predictors of mortality, whereas sex (OR = 7.15, p = 0.043), age (OR = 1.05, p = 0.042), body mass index (OR = 1.35, p = 0.013), NIHSS (OR = 1.12, p = 0.012), and ASPECTS (OR = 0.64, p = 0.024) were independent predictors of poor neurological outcome (mRS 3-5). CONCLUSION Beyond other well-known variables, low masseter attenuation, indicating myosteatosis, represents an independent negative prognostic factor for 90 days mortality in patients successfully reperfused after anterior circulation stroke.

Abstract
PURPOSE Sarcopenia is associated with poor outcomes, and evidence suggests an inverse relationship between skeletal muscle mass and cardiovascular risk. Sarcopenia has been studied after stroke, but its value as a risk factor for stroke has not been examined. This prospective cohort study measured sarcopenia in stroke/TIA patients at baseline to explore its role in predicting recurrent events. METHOD The Arterial Stiffness In lacunar Stroke and TIA (ASIST) study included 96 patients with TIA/lacunar stroke, of which 82 patients (mean age 71.2±10.8 years) had bioimpedance analysis to assess body composition. Skeletal Mass Index (SMI) was calculated and parameters of sarcopenia assessed using Davison (1) and Janssen (2) criteria. Recurrent cerebrovascular events were monitored over 5 years. RESULTS Eighteen patients had recurrent events. On independent samples t test there were significantly more participants with sarcopenia in the recurrent events group (89% vs 56%, p<0.001) using Davison (1) criteria, as well as lower mean SMI, significantly more participants with diabetes and higher arterial stiffness. On binary logistic regression, the only significant predictors of recurrent events were SMI (p=0.036, hazard ratio=0.414, 95% confidence interval 0.195-0.948) and diabetes (p=0.004, hazard ratio=9.06, 95% confidence interval 2.009-40.860) when corrected for age, sex and cardiovascular risk factors. Using Janssen (2) criteria in the regression, severe sarcopenia was a significant predictor of recurrent events (p=0.028). There was a significant association between sarcopenia and recurrent events on Chi square based on Davison (p=0.02) and Janssen (p=0.034) definitions. CONCLUSIONS The presence of baseline sarcopenia in stroke and TIA patients is an independent predictor of recurrent events.

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

Abstract
AIM To investigate the effects of coexisting conditions such as premorbid sarcopenia, frailty, and disability on functional outcomes in older patients with acute stroke. METHODS This prospective cohort study included older patients (aged ≥65 years) hospitalized for acute stroke at a single neurosurgical hospital. Premorbid sarcopenia, frailty, and disability were diagnosed using the strength, assistance with walking, rising from a chair, climbing stairs, and falls (SARC-F) questionnaire, frailty index, and modified Rankin Scale (mRS) on admission. The primary outcome was the mRS score 3 months after stroke, and a poor outcome was defined as mRS ≥4. RESULTS This study included 317 older patients with acute stroke (median [interquartile range] age: 76 [12] years). Premorbid sarcopenia, frailty, and disability (mRS = 2 or 3) were identified in 59 (19%), 27 (9%), and 54 (17%) patients, respectively. Two coexisting conditions were observed in 26 patients (8%), and three were observed in 18 patients (6%). Adjusted logistic regression analysis revealed that coexisting conditions were independently associated with poor outcomes (one condition, adjusted OR: 3.20 [95%CI: 0.98-10.45]; two conditions, adjusted OR: 6.57 [95%CI: 1.74-24.87]; three conditions, adjusted OR: 12.70 [95%CI: 2.65-60.91]). CONCLUSIONS The coexistence of premorbid sarcopenia, frailty, and disability was associated with poor functional outcomes in older patients with acute stroke. Geriatr Gerontol Int 2022; ••: ••-••.

Abstract
BACKGROUND Recent studies have suggested that skeletal muscle area (SMA) and psoas muscle area (PMA), markers for sarcopenia, are associated with the prognosis of many diseases. However, it remains unclear which of the two is a superior prognostic marker. Thus, the objective of this study was to analyse these markers in patients with traumatic brain injury (TBI). METHODS Patients with TBI [abbreviated injury scale (AIS) score of 4 or 5] were selected. Those with an AIS score of 4 or 5 for chest, abdomen, or extremity lesion were excluded. Clinical data, including Glasgow Outcome Scale (GOS), mortality, and anthropometric data, were collected. SMA and PMA were measured. Skeletal muscle index (SMI) and psoas muscle index (PMI) were calculated for each muscle area divided by height squared. The good prognosis group was defined as patients with a GOS score of 4 to 5. The poor prognosis group was defined as those with a GOS score of 1-3. Data of both groups were analysed for the overall prognosis. After excluding patients with a hospital stay of 1 or 2 days, the modified prognosis and mortality of patients were analysed. RESULTS A total of 212 patients were enrolled in the statistical analysis. Patients with good prognosis showed a larger PMA (17.4 cm2 vs. 15.0 cm2, P = 0.002) and PMI (6.1 cm2/ m2 vs. 5.3 cm2/ m2, P = 0.001). After modification, patients with good prognosis showed a larger PMA (17.4 cm2 vs. 14.9 cm2, P = 0.002) and PMI (6.1 cm2/ m2 vs. 5.3 cm2/ m2, P = 0.01). On binary logistic regression analysis, PMI was found to be a significant risk factor for the modified prognosis (Odds ratio (OR) (95% confidence interval (CI)): 0.763 (0.633 - 0.921), P = 0.005) and modified mortality (OR (95% CI): 0.740 (0.573 - 0.957), P = 0.022). CONCLUSION Less amount of psoas muscle (PM) was found to be a significant risk factor for the prognosis of patients with TBI. PM was a better prognostic marker than skeletal muscle (SM) in patients with TBI. Further studies are needed to increase our understanding of sarcopenia and TBI.

Abstract
OBJECTIVES This study aimed to investigate whether phase angle is an indicator of malnutrition and sarcopenia in acute-phase stroke patients. MATERIALS AND METHODS We conducted a retrospective observational study of stroke patients in a single acute-care hospital. The phase angle was measured within 5 days after admission, and the correlation between nutritional status and sarcopenia index was investigated. The cut-off point that distinguishes malnutrition and sarcopenia was evaluated using the receiver operating characteristic curve. The effects of the geriatric nutritional risk index (GNRI) and sarcopenia on the phase angle were examined using multivariate linear regression analysis. RESULTS A total of 211 stroke patients (140 men) with a median age of 74 (65-83) were included in the analysis. Malnutrition was present in 38 (18.0%) patients, and 65 (30.8%) had sarcopenia. The phase angle significantly correlated with GNRI, grip strength, skeletal muscle musss index, and calf circumference in both men and women. The cut-off points for discriminating malnutrition were 5.05 for men and 3.96 for women, while the cut-off points for discriminating sarcopenia were 5.28 for men and 4.62 for women. Multivariate linear regression analysis showed that the GNRI and sarcopenia were independently related to the phase angle. CONCLUSIONS Phase angle is a useful indicator for distinguishing malnutrition and sarcopenia in patients with acute stroke.

Abstract
Irisin, a newly discovered protein hormone that is secreted in response to low frequency whole body vibration (LFV), could be a promising post-stroke rehabilitation therapy for patients who are frail and cannot comply with regular rehabilitation therapy. Irisin is generated from a membrane-bound precursor protein fibronectin type III domain-containing protein 5 (FNDC5). Aside from being highly expressed in muscle, FNDC5 is highly expressed in the brain. The cleaved form of FNDC5 was found in the cerebrospinal fluid as well as in various regions of the brain. Numerous studies suggest that irisin plays a key role in brain metabolism and inflammation regulation. Both the metabolism and inflammation govern stroke outcome, and in a published study, we demonstrated that LFV therapy following middle cerebral artery occlusion significantly reduced innate immune response, improved motor function and infarct volume in reproductively senescent female rats. The observed effect of LFV therapy could be working via irisin, therefore, the current review focuses to understand various aspects of irisin including its mechanism of action on the brain.

Abstract
BACKGROUND Post-stroke dysphagia is a common and expensive complication of acute stroke. The relationship between dysphagia and skeletal muscle loss (sarcopenia) has been recently highlighted. This study aimed to determine the relationship between temporal muscle thickness (TMT) measured by head magnetic resonance imaging (MRI) and dysphagia in patients with acute stroke. METHODS Seventy participants (43 men and 27 women; mean age, 75.6 ± 12.7 years) were included in this study. TMT was measured by T2-magnetic resonance images within seven days of hospitalization. The severity of dysphagia was assessed using the Functional Oral Intake Scale (FOIS). Participants were classified into three categories according to the severity of dysphagia (severe: FOIS score, 1-3; mild: FOIS score, 4-6; normal: FOIS score, 7). Linear regression analysis was used to determine the independent explanators of dysphagia severity. RESULTS Twenty participants (28.6%) had severe dysphagia, 31 participants (44.3%) had mild dysphagia, and 19 participants (27.1%) had normal swallowing function at discharge. The results of the linear regression analysis showed that TMT was a significant explanator of dysphagia severity following stroke, along with age and National Institute of Health Stroke Scale (NIHSS) score (P < 0.05, effect size: f2 = 0.72). CONCLUSIONS TMT was an independent risk factor for dysphagia in patients with acute stroke. Skeletal muscle loss may be secondarily involved in dysphagia with acute stroke, and measurement of TMT with head MRI is a useful method to assess skeletal muscle loss.

Abstract
Stroke is a leading cause of death and disability and is responsible for a significant economic burden. Sarcopenia and cognitive dysfunction are common consequences of stroke, but there is less awareness of the concurrency of these conditions. In addition, few reviews are available to guide clinicians and researchers on how to approach sarcopenia and cognitive dysfunction as comorbidities after stroke, including how to assess and manage them and implement interventions to improve health outcomes. This review synthesises current knowledge about the relationship between post-stroke sarcopenia and cognitive dysfunction, including the physiological pathways, assessment tools, and interventions involved.

Abstract
BACKGROUND AND PURPOSE As a very common risk of adverse outcomes of the ischemic stroke patients, sarcopenia is associated with infectious complications and higher mortality. The goal of this retrospective study is to explore the predictive value of serum Cr/CysC ratio in acute ischemic stroke patients receiving nutritional intervention. METHODS We reviewed adult patients with AIS from December 2019 to February 2020. Patients with acute kidney injury were excluded and all patients received nutritional intervention during a 3-month follow-up period. We collected baseline data at admission including creatinine and cystatin C. The primary poor outcome was major disability (modified Rankin Scale score ≥ 4) at 3 months after AIS. RESULTS A total of 217 patients with AIS were identified for this study. Serum Cr/CysC ratio was significantly correlated with NIHSS at discharge, 1-month modified Rankin Scale score, and 3-month modified Rankin Scale score. During 3 months, 34 (15.70%) patients had a poor outcome after AIS and 11 (5.10%) patients died within 30 days. In multivariable logistic regression analyses, serum Cr/CysC ratio at admission was independently associated with 3-month poor outcomes (OR: 0.953, 95% CI: 0.921-0.986, p = .006) and 30-day mortality (OR: 0.953, 95% CI: 0.921-0.986, p = .006). CONCLUSION As a blood biochemical indexes reflecting the muscle mass and aiding in risk stratification, Cr/CysC ratio at admission could be used as a predictor of 30-day mortality and long-term poor prognosis in AIS patients.

Tanislav C, Kostev K. Factors associated with fracture after stroke and TIA: a long-term follow-up. Osteoporos Int 2020; 31:2395-2402. [PMID: 32647951 DOI: 10.1007/s00198-020-05535-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Accepted: 07/01/2020] [Indexed: 01/20/2023]
Abstract
UNLABELLED We assessed the long-term incidence of fractures after stroke and TIA and analyzed associated factors. The fracture incidence increases with age and is higher in stroke than in TIA. Dementia is associated with fractures after both. Our results indicate tailored measures are necessary for preventing fractures after stroke or TIA. INTRODUCTION In the present study, we aimed to assess the long-term incidence of fractures and analyze associated factors after stroke or transient ischemic attack (TIA). METHODS The current cohort study included patients who had received an initial ischemic stroke or TIA diagnosis documented anonymously in the Disease Analyzer database (IQVIA) between 2000 and 2016 by physicians in 1262 general practices in Germany. Univariate Cox and multivariate regression models were carried out. RESULTS Three groups (stroke, TIA, no stroke/TIA), each with 12,265 individuals, were selected (mean age 67.3 years, 48.1% female). A fracture was diagnosed in 12.9% of stroke patients and in 11.4% of TIA patients. Among male stroke patients, 11.1% had a fracture (15.4% among female stroke patients). The hazard ratio (HR) for fractures after stroke was 1.26 (CI: 1.15-1.39) and for fractures after TIA, it was 1.14 (CI: 1.03-1.25). In female stroke patients, the HR for fractures was 1.32 (CI: 1.15-1.60), while in males, it was 1.20 (CI: 1.03-1.39). Among TIA patients, females had an elevated HR for fractures (HR: 1.21; CI: 1.06-1.37). In individuals aged ≥ 80 years, an increased risk for fractures was only detected among TIA patients (HR: 1.26; CI: 1.05-1.51). Dementia and non-opioid analgesic therapy were positively associated with fracture after both stroke and TIA. CONCLUSION Stroke was positively associated with fracture in patients < 80 years, while TIA was positively associated with fracture in patients ≥ 80 years and females. Dementia and analgesic therapy were also associated with fracture after either stroke or TIA.

Abstract
Purpose of review to evaluate recent scientific research studies related to the changes in skeletal muscle after stroke and the presence of sarcopenia in stroke survivors to establish its incidence and effects on function. Recent Findings Recently published findings on stroke-related sarcopenia are limited. This might be due to changes in the consensus definition of sarcopenia. Sarcopenia in stroke patients is estimated at 14 to 54%. The presence of sarcopenia at the time of a stroke can lead to worse recovery and functional outcomes. Summary Presence of sarcopenia prior to a stroke may be more common than suspected and can lead to worse functional recovery. Clinicians should be aware of this to better identify and treat stroke-related sarcopenia. Future research should focus on larger population studies to more accurately establish correlation between stroke and sarcopenia.

Physical Exercise and Myokines: Relationships with Sarcopenia and Cardiovascular Complications. Int J Mol Sci 2020; 21:ijms21103607.

Abstract
Skeletal muscle is capable of secreting different factors in order to communicate with other tissues. These mediators, the myokines, show potentially far-reaching effects on non-muscle tissues and can provide a molecular interaction between muscle and body physiology. Sarcopenia is a chronic degenerative neuromuscular disease closely related to cardiomyopathy and chronic heart failure, which influences the production and release of myokines. Our objective was to explore the relationship between myokines, sarcopenia, and cardiovascular diseases (CVD). The autocrine, paracrine, and endocrine actions of myokines include regulation of energy expenditure, insulin sensitivity, lipolysis, free fatty acid oxidation, adipocyte browning, glycogenolysis, glycogenesis, and general metabolism. A sedentary lifestyle accelerates the aging process and is a risk factor for developing sarcopenia, metabolic syndrome, and CVD. Increased adipose tissue resulting from the decrease in muscle mass in patients with sarcopenia may also be involved in the pathology of CVD. Myokines are protagonists in the complex condition of sarcopenia, which is associated with adverse clinical outcomes in patients with CVD. The discovery of new pathways and the link between myokines and CVD remain a cornerstone toward multifaceted interventions and perhaps the minimization of the damage resulting from muscle loss induced by factors such as atherosclerosis.
