RESUMEN
PURPOSE: Evidence is scarce regarding the association between anemia and alterations in cognitive level among hospitalized older patients. We aimed to evaluate the associations between baseline hemoglobin (Hb) levels and changes in cognitive level in patients undergoing rehabilitation after stroke. METHODS: A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients. Data on serum Hb levels were extracted from medical records, specifically tests conducted within 24 hours of admission. Primary outcomes included discharge scores for cognitive function assessed by the cognitive domain of the Functional Independence Measure (FIM-cognition) and the corresponding change in FIM-cognition during hospitalization. Another outcome measure was the length of hospital stay. Multivariate linear regression analyses were employed to assess the association between Hb levels at admission and the designated outcomes, adjusting for potential confounding factors. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median Hb level at admission was 13.3 [11.9, 14.5] g/dL. After fully adjusting for confounding factors, the baseline Hb level was significantly and positively associated with FIM-cognition at discharge (ß = 0.045, p = 0.025) and its gain (ß = 0.073, p = 0.025). Further, the baseline Hb level was independently and negatively associated with length of hospital stay (ß = -0.013, p = 0.026). CONCLUSION: Elevated baseline Hb levels are correlated with preserved cognitive level and shorter hospital stays in post-stroke patients. Evaluating anemia at the outset serves as a crucial prognostic indicator.

PURPOSE: Evidence is scarce on the associations between impaired oral health and cognitive level related to independence in activities of daily living (ADLs) among hospitalized older patients. We aimed to evaluate the associations between baseline oral problems and changes in cognitive level in post-stroke patients. METHODS: A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients. Revised Oral Assessment Guide (ROAG) as a measure of oral health and function was assessed at admission. Primary outcomes included discharge scores for cognitive function assessed by the cognitive domain of the Functional Independence Measure (FIM-cognition) and the corresponding change in FIM-cognition during hospitalization. Another outcome measure was the motor domain of FIM (FIM-motor). Multivariate linear regression analyses were employed to assess the association between baseline ROAG and the designated outcomes, adjusting for potential confounding factors. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median ROAG was 10 [9, 12], with 811 patients (84.9%) presenting oral problems. After fully adjusting for confounding factors, the ROAG was significantly and negatively associated with FIM-cognition at discharge (ß = -0.107, p = 0.031) and FIM-cognition gain (ß = -0.093, p = 0.018). Further, the ROAG was independently and negatively associated with FIM-motor at discharge (ß = -0.043, p = 0.013) and FIM-motor gain (ß = -0.065, p = 0.013). CONCLUSION: Oral problems were associated with compromised cognitive levels and a decline in physical function during the hospitalization in post-stroke patients. These results underscore the critical importance of addressing oral health in this patient population.
RESUMEN
PURPOSE: Oral problems and muscle health are indeed significant concerns in ageing populations. However, there is limited evidence concerning the association between these issues. The study's focus was to investigate the association between oral problems and sarcopenic obesity, wherein sarcopenia and obesity coexist concurrently, in post-stroke patients. METHODS: This retrospective, observational, cross-sectional study included patients hospitalised for post-stroke rehabilitation. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). Sarcopenic obesity was diagnosed according to the European Society of Clinical Nutrition and Metabolism/European Association for the Study of Obesity criteria. Multiple linear regression analysis was used to examine the association between the ROAG and sarcopenic obesity after adjusting for confounding factors. RESULTS: A total of 760 patients were included, with a mean (SD) age of 71 (9) years, of whom 408 (54.7%) were male. The median (interquartile range, 25th and 75th percentiles) ROAG was 11 [9, 13]. Sarcopenic obesity was diagnosed in 16 (3.9%) men, 18 (5.1%) women, and 34 (4.5%) patients overall. Multivariate linear analysis showed that ROAG was significantly and positively associated with sarcopenic obesity (ß = .091, P = .023), followed by obesity alone (ß = .084, P = .044), and sarcopenia alone (ß = .081, P = .037). CONCLUSION: Oral problems were associated with sarcopenic obesity in post-stroke. Oral assessment and intervention may have a positive impact on ADL and QOL in post-stroke patients with sarcopenic obesity.
RESUMEN
Extracellular histones induce endothelial damage, resulting in lung haemorrhage; however, the underlying mechanism remains unclear. Factor XIII, as a Ca2+-dependent cross-linking enzyme in blood, mediates fibrin deposition. As another isozyme, transglutaminase 2 (TG2) has a catalytic activity distributing in most tissues. Herein, we investigated whether TG2 promotes fibrin deposition and mediates the adhesion of platelets to ECs in histone-induced acute lung injury (ALI). We evaluated the lung histology and the adhesion of platelets to endothelial cells (ECs) after injecting histones to wild-type (WT) C57BL/6J and TG2 knockout (TG2-/-) mice, and administered a TG2 inhibitor (NC9) to WT mice. Pulmonary haemorrhage was more severe in TG2-/- mice than that in WT mice. The area of fibrin deposition and the proportion of CD41+CD31+ cells were lower in TG2-/- mice than in WT mice. Pre-treatment of NC9 decreased the area of fibrin deposition and the proportion of CD41+CD31+ cells in WT mice. These results suggest that TG2 prevents from pulmonary haemorrhage in ALI by promoting the adhesion of platelets to ECs and the fibrin deposition.

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

OBJECTIVES: To investigate the effect of trunk and appendicular skeletal muscle mass on the swallowing function at discharge in acute stroke patients. MATERIALS AND METHODS: This retrospective cohort study included patients hospitalized after acute strokes. Skeletal muscle mass was measured by bioelectrical impedance analysis within 5 days of admission. The primary outcome was swallowing function at acute hospital discharge, assessed using the Functional Oral Intake Scale (FOIS). Secondary outcomes were Functional Independence Measure-eating (FIM-eating) scores and length of hospital stay. RESULTS: Data from 231 patients (age 72.2 years; 151 men) were included in the analysis. The median trunk muscle mass index (TMI) was 8.2 and 6.8 kg/m2 in men and women, respectively. The median appendicular skeletal muscle mass index (ASMI) was 7.7 and 5.7 kg/m2 in men and women, respectively. The high TMI group had higher FIM-eating scores at discharge in each sex (p < 0.001). The high ASMI group had higher FOIS (p = 0.039 and 0.048) and FIM-eating scores at discharge (p = 0.046 and 0.047) in men and women, respectively. On multivariate analysis, TMI was independently associated with FIM-eating scores (ß = 0.330, p < 0.001); ASMI was independently associated with FOIS (ß = 0.229, p = 0.039) and FIM-eating scores (ß = 0.111, p = 0.032). CONCLUSIONS: Skeletal muscle mass had site-specific impacts on swallowing function and eating activities. This finding may contribute to the design of more individualized rehabilitation programs.

OBJECTIVE: Evidence regarding the effect of sarcopenic obesity on recovery in stroke patients is scarce in rehabilitation medicine. The aim of this study was to examine the association between changes in muscle strength and functional outcomes in patients with sarcopenic obesity undergoing rehabilitation after stroke. MATERIALS AND METHODS: This study was a retrospective cohort study of stroke patients, consecutively admitted to post-acute rehabilitation wards of a single hospital, of which, only those diagnosed with sarcopenic obesity at admission were included in the final analysis. Bioimpedance analysis was used to measure skeletal muscle mass and body fat mass. Sarcopenic obesity was defined as the presence of both sarcopenia and obesity. Sarcopenia was diagnosed using muscle mass index and handgrip strength. Obesity was diagnosed using body fat percentage (men ≥30%, women ≥35%). The evaluated outcomes were Functional Independence Measure (FIM)-motor score at discharge and its gain. Multiple regression analysis was used to verify whether changes in hand grip strength during hospitalization were associated with functional outcomes. RESULTS: Sixty-two patients (29 men) with a mean age of 78 years, were analyzed. The mean change in the hand grip strength was 3.9 kg. In multiple regression analysis, changes in the hand grip strength were significantly associated with FIM-motor at discharge (ß = 0.34, P < 0.01) and FIM-motor gain (ß = 0.58, P < 0.01). CONCLUSIONS: Muscle strength gain was associated with improved functional recovery in stroke patients with sarcopenic obesity.

OBJECTIVE: Oral problems affect rehabilitation outcomes. This study aimed to examine the association between improvement in oral health and functional outcomes in patients after stroke. MATERIALS AND METHODS: This retrospective cohort study included post-acute rehabilitation patients who presented with oral problems at admission. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). The ROAG score change during hospitalization was calculated by subtracting the score at admission from the score at discharge; oral problems were defined as "improved", when the score change value was lower than the median value. Study outcomes were the activities of daily living assessed by the motor domain of the Functional Independence Measure (FIM-motor) scores and dysphagia as assessed by the Food Intake Level Scale (FILS). Multivariate regression analyses were used to determine whether improved oral problems were associated with study outcomes. P-values of <0.05 were considered statistically significant. RESULTS: This study included 300 patients (mean age, 72.0 years; 51.7% men). The median [IQR] baseline ROAG score and its change value during hospitalization were 11 [10, 14] and -1[-3, 0] points, respectively. Multivariate analyses showed that improved oral problems was independently associated with FIM-motor score (ß = 0.144, p = 0.001) and FILS score (ß = 0.227, p < 0.001) at discharge, after adjusting for potential confounders. CONCLUSIONS: Improvement in oral health was positively associated with recovery of the ADL and dysphagia after stroke. Early detection of oral problems and oral treatment should be implemented in these patients to maximize functional recovery.

OBJECTIVES: To evaluate the associations between estimated glomerular filtration rate (eGFR) and sarcopenia and functional outcomes after stroke. METHODS: This retrospective cohort study included hospitalized patients after stroke. Data on serum creatinine-based eGFR were extracted from medical records. Primary outcome was the presence of sarcopenia at admission, diagnosed based on both low skeletal muscle mass and strength criteria as per the AWGS 2019. Other outcomes included the Food Intake Level Scale (FILS) score (measure of dysphagia, FILS score <7) at discharge and the Functional Independence Measure-motor (FIM-motor) score at discharge and its change from the baseline. Multivariate analyses were performed to determine the association between eGFR and outcomes. RESULTS: Data from 813 patients (mean age 73.5 years; 51.9% men) were included in the analysis. The median eGFR was 65.1 ml/min/1.73 m2, and about 41% of patients had an eGFR less than 60 ml/min/1.73 m2 at the baseline. Sarcopenia was observed in 47.4% of patients. In the multivariate analyses, baseline eGFR was positively associated with sarcopenia at admission (odds ratio [OR]=1.016, 95% confidence interval [CI]: 1.005-1.027, p = 0.003), the presence of dysphagia at discharge (OR=1.016, 95% CI: 1.001-1.031, p = 0.045), and negatively associated with FIM-motor score at discharge (ß= -0.046, p = 0.047) and its gain (ß= -0.067, p = 0.037). CONCLUSIONS: Elevated creatinine-based eGFR is associated with sarcopenia, dysphagia, and adverse rehabilitation outcomes after stroke. Our findings highlight the limitations of assessing renal function using creatinine levels in patients with sarcopenia: therefore, future studies using cystatin C are needed to validate our findings.

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

BACKGROUND: Despite the growing interest in oral health and chronic disease in geriatric medicine, the evidence of an association between the two variables is limited. OBJECTIVES: This study sought to examine the association between oral health status and chronic kidney disease (CKD) in this setting. MATERIALS AND METHODS: This retrospective study included consecutive post-acute patients in a rehabilitation hospital. Oral health status was evaluated using the Revised Oral Assessment Guide (ROAG). Renal function or CKD stage was assessed by measurement of the estimated glomerular filtration rate (eGFR). Multivariate logistic regression analysis was used to determine which subcategories of ROAG were independently associated with advanced CKD stages (vs. early CKD stages). Multiple linear regression analysis was used to clarify whether eGFR on admission was independently associated with ROAG score after adjusting for potential confounders. RESULTS: A total of 1056 (mean age 70 years; 52% women) were included in the analysis. Slight and moderate-to-severe oral health problems were detected in 57.7% and 15.4% of patients, respectively. Patients with oral problems had a more severe stage of CKD (P = .036) and a lower eGFR (P = .028). Among subitems of ROAG, tongue (OR = 1.40, P = .041), saliva (OR = 1.72, P = .039) and oral cavity mucosa (OR = 1.37, P = .013) status was independently associated with the presence of CKD stages 3, 4 and 5. Furthermore, eGFR was independently associated with ROAG score (ß = -0.180, P = .034) after adjusting for possible confounders. CONCLUSIONS: Impaired oral health status is common and closely associated with CKD in post-acute inpatients.

As Japan's population ages, there is a growing interest in regional health care coordination. Our study aimed to evaluate whether the interval between onset and admission to convalescent rehabilitation wards (onset-admission) was associated with outcomes in ischemic stroke patients. We conducted a retrospective cohort study in a single rehabilitation hospital. Ischemic stroke patients consecutively admitted to the wards were eligible to enroll. Outcomes included Functional Independence Measure (FIM)-motor gain, the Food Intake Level Scale (FILS) and a discharge rate to home. FIM assesses functional independence, including motor (FIM-motor) and cognitive domains, and is a measure of activities of daily living (ADLs). The FIM-motor gain indicates the difference between the FIM-motor scores at admission and discharge. FILS is a 10-point observer-rated scale to measure swallowing. After enrollment, 481 patients (mean age 74.4 years; 45.7% women) were included. The median [interquartile range] onset-admission interval was 13 [10-20] days and the median National Institute of Health Stroke Scale score, a measure of stroke severity, was 8 [3-13]. In multivariate analysis, the onset-admission interval was independently associated with FIM-motor gain (ß = -0.107, p = 0.024), FILS score at discharge (ß = -0.159, p = 0.041), and the rate of discharge to home (odds ratio: 0.946, p = 0.032). In conclusion, a shorter interval between stroke onset and admission to convalescent rehabilitation wards contributes to improved outcomes, including ADLs, dysphagia, and a discharge rate to home, in ischemic stroke patients, regardless of stroke severity.

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

OBJECTIVE: The aim of our study was to evaluate the associations between baseline hemoglobin (Hb) levels and sarcopenia and outcomes in patients undergoing rehabilitation after stroke. METHODS: This retrospective cohort study included consecutive hospitalized post-stroke patients. Data on serum Hb level were extracted from medical records on tests performed within 24 h of admission. Primary outcome was the presence of sarcopenia at admission, diagnosed based on both low skeletal muscle mass and strength criteria per recently updated Asian Working Group for Sarcopenia 2019 guidelines. Other outcomes included the Functional Independence Measure-motor (FIM-motor) score at discharge and its change from baseline, and the Food Intake Level Scale (FILS) score (measure of dysphagia, FILS score < 7) at discharge. Multivariate analyses were used to determine the association between Hb levels at admission and outcomes of interest, adjusted for potential confounders. RESULTS: Data from 598 patients (mean age 72.1 years; 52.7% men) were included in the analysis. The mean Hb level at admission was 13.2 g/dL, and 86 (27.3%) men and 102 (36.0%) women had low Hb levels, i.e., 13.0 g/dL and 12.0 g/dL, respectively. In multivariate analyses, the baseline Hb level was independently associated with sarcopenia (odds ratio [OR]: 0.794, 95% confidence interval [CI]: 0.677-0.930, pâ¯=â¯0.004), FIM-motor score (ßâ¯=â¯0.096, pâ¯=â¯0.045) at discharge and its change from baseline (ßâ¯=â¯0.191, pâ¯=â¯0.018), and dysphagia (OR: 0.762, 95% CI: 0.595-0.961, pâ¯=â¯0.041) at discharge. CONCLUSION: Baseline low Hb levels were associated with sarcopenia, poorer recovery of physical function, and dysphagia in patients undergoing rehabilitation after stroke.

Objective: Sarcopenia negatively affects the short-term prognosis of hospitalized older adults. However, no evidence currently supports a direct relationship between sarcopenia and readmission among individuals who have experienced an acute stroke. Therefore, we investigated whether sarcopenia is associated with readmission after discharge. Methods: This retrospective cohort study included patients who had experienced acute stroke. Sarcopenia was defined as the coexistence of low skeletal muscle mass index (SMI) and grip strength. We applied the log-rank test and Cox proportional hazards regression analysis to analyze whether sarcopenia, low SMI, and low grip strength were associated with readmission within 6 months. Results: Among 228 included patients (mean age, 72.8 years; 146 males), the prevalence of sarcopenia was 24.6% (n=56; male, 17.8%; female, 36.6%). Cox proportional hazards regression analysis using the propensity score as a covariate revealed that sarcopenia (hazard ratio [HR] 7.21 [95% confidence interval (CI) 1.45-35.8]; p=0.016) and low skeletal muscle mass (HR 7.40 [95% CI 1.14-48.1; p=0.036), but not low grip strength (HR 1.42 [95% CI 0.281-7.21]; p=0.670), were significantly associated with readmission for stroke within 6 months. Conclusions: Sarcopenia was negatively associated with readmission within 6 months of stroke onset in patients in Japan who had experienced an acute stroke. These findings suggest that the identification of sarcopenia may facilitate prognostic prediction from the acute stage and intervention(s) to prevent rehospitalization.
RESUMEN
AIM: Addressing sarcopenia and frailty in aging populations is crucial for enhancing quality of life and reducing healthcare dependence. While the importance of energy, protein, and amino acid supplementation is known, the role of minerals needs further exploration. This systematic review evaluates the effectiveness of these minerals in managing sarcopenia and frailty. METHODS: We analyzed data from the Cochrane Central Register of Controlled Trials, MEDLINE, and Ichu-shi Web from January 2000 to March 2023. Studies were selected if they were interventional or observational, focused on individuals with frailty or sarcopenia who were aged 65 or older, and involved mineral supplementation. The risk of bias in these studies was assessed using the Cochrane Risk of Bias 2 tool. RESULTS: Of the 615 studies identified, seven met the inclusion criteria. These studies mainly focused on the effects of combined nutrient supplements, with few focusing on individual minerals. The findings were mixed, demonstrating some improvements in muscle strength, activity of daily living, and cognitive functions. Notably, minerals appeared to offer benefits as part of multi-nutrient interventions, especially for cognitive and immune health, but had limited impact on muscle mass or strength when used alone. The limited number and variable outcomes of studies precluded a feasible meta-analysis. CONCLUSIONS: The effect of mineral supplementation on sarcopenia and frailty remains uncertain, suggesting a need for tailored nutritional strategies. Future studies should aim for well-designed clinical trials in order to gain a better understanding of the roles of minerals in improving muscle health and functional outcomes, leading to clearer recommendations for clinical practice.

RESUMEN
BACKGROUND: This study aimed to determine whether changes in phase angle during rehabilitation are associated with clinical outcomes such as activities of daily living (ADL), skeletal muscle mass index (SMI), and strength in patients with osteoporotic fractures. METHODS: This retrospective observational study included patients with osteoporotic fractures admitted to convalescent rehabilitation wards. Changes in phase angle were defined as the difference between the phase angle values at discharge and on admission. The primary outcome was the Functional Independence Measure motor (FIM-motor) score at discharge. The secondary outcomes were SMI and handgrip strength at discharge. We used multivariate analysis to adjust for confounding factors and examine the association between changes in the phase angle and outcomes. RESULTS: We analyzed a total of 115 patients (97 women, mean age of 81.0±10.0 years), with a median change in phase angle of 0° during hospitalization. We observed increased phase angles in 49 patients (43%), with a median increase of 0.2°. Multiple regression analysis showed that changes in phase angle were independently associated with FIM-motor score at discharge (ß=0.238, p=0.027). Changes in phase angle were not significantly associated with SMI (ß=0.059, p=0.599) or handgrip strength (ß=-0.032, p=0.773) at discharge. CONCLUSION: An increased phase angle during rehabilitation was positively associated with ADL improvement in patients with osteoporotic fractures. These findings may help clinicians make informed decisions regarding patient care and treatment strategies for better outcomes.

Objectives: The purpose of this study was to examine the association between baseline dysphagia and the improvement of activities of daily living performance and cognitive level among inpatients after stroke. Methods: This was a retrospective cohort study of patients undergoing convalescent rehabilitation after stroke. Dysphagia was assessed using the Food Intake LEVEL Scale. Outcomes were the motor and cognitive scores of the Functional Independence Measure (FIM) at discharge. Multiple regression analysis was performed to examine the association between dysphagia at admission and these outcomes. Results: There were 499 participants with a median age of 74 years. A multiple regression analysis was carried out after adjusting for potential confounders including age and sex. Dysphagia at admission was independently and negatively associated with motor (ß=-0.157, P<0.001) and cognitive (ß=-0.066, P=0.041) FIM scores at discharge. Conclusions: Baseline dysphagia in patients after stroke was negatively associated with improvement in performance of activities of daily living and cognitive level.
RESUMEN
Acute lung injury (ALI), which occurs in association with sepsis, trauma, and coronavirus disease 2019 (COVID-19), is a serious clinical condition with high mortality. Excessive platelet-leukocyte aggregate (PLA) formation promotes neutrophil extracellular trap (NET) release and thrombosis, which are involved in various diseases, including ALI. Macrophage-1 antigen (Mac-1, CD11b/CD18), which is expressed on the surface of leukocytes, is known to promote NET formation. This study aimed to elucidate the role of Mac-1 in extracellular histone-induced ALI. Exogenous histones were administered to Mac-1-deficient mice and wild-type (WT) mice with or without neutrophil or platelet depletion, and several parameters were investigated 1 h after histone injection. Depletion of neutrophils or platelets improved survival time and macroscopic and microscopic properties of lung tissues, and decreased platelet-leukocyte formation and plasma myeloperoxidase levels. These improvements were also observed in Mac-1-/- mice. NET formation in Mac-1-/- bone marrow neutrophils (BMNs) was significantly lower than that in WT BMNs. In conclusion, our findings suggest that Mac-1 is associated with exacerbation of histone-induced ALI and the promotion of NET formation in the presence of activated platelets.

BACKGROUND: Anticholinergic burden is associated with adverse events in the older adults. However, there is a lack of evidence regarding its effect on urinary independence in stroke patients. AIM: This study examined the association between increased anticholinergic burden during hospitalization and urinary independence in post-stroke patients undergoing rehabilitation. METHOD: This observational cross-sectional study included stroke patients admitted to a post-acute rehabilitation hospital between 2020 and 2022 who were not independently urinating. The degree of urinary independence was assessed using the Functional Independence Measure-Bladder (FIM-Bladder), a subscale of the motor domain of the FIM, and urinary independence was defined as FIM-Bladder ≥ 6. Anticholinergic burden was assessed using the anticholinergic risk scale (ARS), and changes in ARS during hospitalization were calculated by subtracting the value at admission from the value at discharge. The study outcome was urinary independence at discharge. Logistic regression analysis was used to examine whether change in ARS score was independently associated with the outcome. Statistical significance was set at P < 0.05. RESULTS: Of the 573 patients enrolled, 312 patients (mean age 77.5 years, 51.9% male) were included in the analysis. ARS increased during hospitalization in 57 patients (18.3%). Change in ARS score was independently associated with urinary independence (odds ratio: 0.432, 95% confidence interval: 0.247-0.756, P = 0.003). CONCLUSION: Increased anticholinergic burden in post-stroke patients who require assistance with urination is significantly associated with less independent urination. Anticholinergic agents may need to be introduced cautiously in patients who require assistance with urination.
