RESUMO
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.
RESUMO
Objectives: Evidence is scarce regarding the association between hyponatremia and functional outcomes among older hospitalized patients. We aimed to evaluate the associations between baseline hyponatremia and improvement in activities of daily living (ADL) and muscle health in hospitalized post-stroke patients. Methods: This retrospective cohort study included hospitalized post-stroke patients. Serum sodium concentrations were extracted from medical records based on blood tests performed within 24 h of admission, with hyponatremia defined as a serum sodium concentration below135 mEq/L. Primary outcome was the discharge ADL as assessed by the motor domain of the Functional Independence Measure (FIM-motor) and its corresponding gain during hospitalization. Other outcomes encompassed the discharge scores for skeletal muscle mass (SMI) and handgrip strength (HGS). Multivariate linear regression analyses were used to determine the association between hyponatremia and outcomes of interest, adjusted for potential confounders. Results: Data from 955 patients (mean age 73.2 years; 53.6% men) were analyzed. The median baseline blood sodium level was 139 [interquartile range: 137, 141] mEq/L, and 84 patients (8.8%) exhibited hyponatremia. After full adjustment for confounders, baseline hyponatremia was significantly and negatively associated with FIM-motor at discharge (ß=-0.036, P=0.033) and its gain during hospital stay (ß=-0.051, P=0.033). Baseline hyponatremia exhibited an independent and negative association with discharge HGS (ß=-0.031, P=0.027), whereas no significant association was found between baseline hyponatremia and discharge SMI (ß=-0.015, P=0.244). Conclusions: Baseline hyponatremia demonstrated a correlation with compromised ADL and muscle health in individuals undergoing rehabilitation after stroke.
RESUMO
Background: Systemic inflammation is associated with poor functional outcomes. However, the effects of improved inflammation on functional indicators remain unclear. This study aimed to clarify the relationship between improvements in systemic inflammation and activities of daily living (ADL) in patients after stroke. Methods: This retrospective cohort study included patients post stroke with systemic inflammation upon admission. Systemic inflammation was defined as a modified Glasgow Prognostic Score (mGPS) score of 1-2. Improvement in systemic inflammation was defined as a reduction in mGPS score or blood C-reactive protein (CRP) levels during hospitalization. The primary outcomes were the motor items of the Functional Independence Measure (FIM-motor) at discharge. We applied multiple linear regression analysis to examine whether reduced systemic inflammation was associated with outcomes after adjusting for confounding factors. Results: Of the 1490 patients recruited, 158 (median age, 79 years; 88 men) had systemic inflammation on admission and were included in the study. Among these patients, 131 (82.9%) and 147 (93.0%) exhibited reduced mGPS and CRP levels, respectively. The median change in CRP was 2.1 [1.1, 3.8] mg/dL. Multivariate analysis revealed that improvements in mGPS (ß = 0.125, p = 0.012) and CRP levels (ß = 0.108, p = 0.108) were independently and positively associated with FIM-motor at discharge. Conclusions: Improvement in systemic inflammation was positively associated with functional outcomes in patients post stroke. Early detection and therapeutic intervention for systemic inflammation may further improve outcomes in these patients.
RESUMO
PURPOSE: Evidence is scarce regarding the association between hyponatremia and alterations in cognitive function among hospitalized older patients. We aimed to investigate the associations between hyponatremia and the baseline cognitive status, as well as the improvement in cognitive function, in hospitalized post-stroke patients. METHODS: This retrospective cohort study included consecutive hospitalized post-stroke patients. Serum sodium concentrations were extracted from medical records based on blood tests performed within 24 h of admission, with hyponatremia defined as a serum sodium concentration < 135 mEq/L. The main outcomes included admission and discharge scores for cognitive levels, assessed through the cognitive domain of the Functional Independence Measure (FIM-cognition), as well as the score changes observed during the hospitalization period. Multivariate linear regression analyses were used to determine the association between hyponatremia and outcomes of interest, adjusted for potential confounders. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6 % men) were included in the analysis. The median baseline blood sodium level was 139 [137, 141], and 84 patients (8.8 %) exhibited hyponatremia. After full adjustment for confounders, the baseline hyponatremia was significantly and negatively associated with FIM-cognition values at admission (ß = -0.009, p = 0.016), discharge (ß = -0.038, p = 0.043), and the gain during hospital stay (ß = -0.040, p = 0.011). CONCLUSION: Baseline hyponatremia has demonstrated a correlation with decline in cognitive level over the course of rehabilitation in individuals after stroke. Assessing hyponatremia at the outset proves to be a pivotal prognostic indicator.

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.

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.

AIM: There is limited evidence concerning the association between anemia and alterations in muscle health among hospitalized older patients. We aimed to evaluate the associations between baseline hemoglobin (Hb) levels and changes in muscle function in patients undergoing rehabilitation after stroke. METHODS: This retrospective cohort study included consecutive hospitalized post-stroke patients. Data on serum Hb level were extracted from medical records on tests performed within 24 h of admission. The main outcomes were discharge score for the skeletal muscle mass index (SMI) obtained through bioimpedance analysis and the corresponding change in SMI during hospitalization. Other outcomes were handgrip strength (HGS) at discharge and the alteration in HGS during hospitalization. Multivariate linear regression analyses were used to determine the association between Hb levels at admission and outcomes of interest, adjusted for potential confounders. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median Hb level at admission was 13.3 [11.9, 14.5] g/dL. After fully adjusting for confounding factors, the baseline Hb level was significantly and positively associated with SMI at discharge (ß = 0.046, P = 0.039) and with SMI gain (ß = 0.010, P = 0.039). Further, the baseline Hb level was independently and positively associated with HGS at discharge (ß = 0.058, P = 0.014) and with its change from baseline (ß = 0.100, P = 0.014). CONCLUSION: Diminished baseline Hb levels were demonstrated be correlated with compromised muscle health in patients after stroke. Evaluating anemia at the outset serves as a crucial prognostic indicator. Geriatr Gerontol Int 2024; 24: 305-311.

BACKGROUND & AIMS: Evidence is limited concerning the association between bioimpedance analysis-derived phase angle and sarcopenic obesity. This study examined this association in patients who underwent convalescent rehabilitation after stroke. METHODS: This cross-sectional study included hospitalized patients with post-acute stroke. The phase angle was measured using a multifrequency bioimpedance analysis. Sarcopenic obesity was diagnosed according to the European Society of Clinical Nutrition and Metabolism/European Association for the Study of Obesity criteria. A multiple linear regression analysis was used to examine the association between the phase angle and sarcopenic obesity after adjusting for confounding factors. A receiver operating characteristic curve was used to calculate the optimal phase angle cutoff value for predicting sarcopenic obesity. RESULTS: A total of 760 patients (median age 71 years; 352 women) were analyzed. The median (interquartile range, 25th and 75th percentiles) phase angle was 4.45° (4.10°, 4.88°). Sarcopenic obesity was diagnosed in 16 (3.9%) men, 18 (5.1%) women, and 34 (4.5%) patients overall. The multiple linear regression analysis showed that sarcopenic obesity (ß = -0.185, p = 0.017) and sarcopenia (ß = -0.121, p = 0.012) were significantly and negatively associated with the phase angle. Obesity was not significantly associated with the phase angle (ß = -0.078, p = 0.094). The optimal cutoff value of the phase angle for diagnosing sarcopenic obesity was 4.29° (sensitivity 0.65, specificity 0.80, area under the curve [AUC] 0.79, 95% CI 0.77-0.87, p < 0.001) in men and 3.84° (sensitivity 0.67, specificity 0.84, AUC 0.81, 95% CI 0.79-0.86, p < 0.001) in women. CONCLUSION: The phase angle was associated with sarcopenic obesity, and the cutoff values of the phase angle that could predict sarcopenic obesity were 4.29° for men and 3.84° for women. This simple and practical phase angle-based prediction of sarcopenic obesity can be useful in clinical practice.

Background: Patients with cardiogenic shock due to acute myocardial infarction (AMI) can rapidly undergo veno-arterial extracorporeal membrane oxygenation (VA-ECMO) therapy to recover cardiac output and decrease mortality. However, the clinical indicators predictive of mortality in these patients remain unknown. MethodsâandâResults: We conducted a single-center retrospective cohort study targeting AMI patients undergoing VA-ECMO. All 63 patients undergoing VA-ECMO for AMI at the Japanese Red Cross Kumamoto Hospital between January 1, 2010 and June 30, 2020 were enrolled. An exploratory analysis was conducted using a survival tree model and variables selected in a univariate Cox proportional hazard model. The median survival time from the start of VA-ECMO was 6.3 days, and 77.8% (n=49) of patients died. Survival analysis divided patients into 3 groups based on 2 parameters at the initial medical examination: Group 1, patients with neither hyperglycemia (blood glucose ≥213 mg/dL) nor thrombocytopenia (platelets ≤145,100/µL); Group 2, patients with hyperglycemia; and Group 3, patients with hyperglycemia plus thrombocytopenia. Relative to Group 1, the risk of in-hospital mortality was significantly increased in Group 2 (hazard ratio [HR] 2.25; 95% confidence interval [CI] 1.13-4.46), and that risk further increased in Group 3 (HR 7.60; 95% CI 3.21-17.95). Conclusions: Hyperglycemia plus thrombocytopenia on initial medical examination combinatorially increase the risk of mortality in patients with cardiogenic shock due to AMI undergoing VA-ECMO.
RESUMO
Septic shock-associated mortality in intensive care units (ICUs) remains high, with reported rates ranging 30-50%. In particular, Gram-negative bacilli (GNB), which induce significant inflammation and consequent multiple organ failure, are the etiological bacterial agent in 40% of severe sepsis cases. Hemoperfusion using polymyxin B-immobilized fiber (PMX), which adsorbs endotoxin, is expected to reduce the inflammatory sepsis cascade due to GNB. However, the clinical efficacy of this treatment has not yet been demonstrated. Here, we aimed to verify the efficacy of endotoxin adsorption therapy using PMX through a retrospective analysis of 413 patients who received broad spectrum antimicrobial treatment for GNB-related septic shock between January 2009 and December 2012 in 11 ICUs of Japanese tertiary hospitals. After aligning the patients' treatment time phases, we classified patients in two groups depending on whether PMX hemoperfusion (PMXHP) therapy was administered or not within 24 hours after ICU admission (PMXHP group: n = 134, conventional group: n = 279). The primary study endpoint was the mortality rate at 28 days after ICU admission. The mean age was 72.4 (standard deviation: 12.6) years, and the mean Sequential Organ Failure Assessment score at ICU admission was 9.9 (3.4). The infection sites included intra-abdominal (38.0%), pulmonary (18.9%), and urinary tract (32.2%), and two thirds of all patients had GNB-related bacteremia. Notably, the mortality at 28 days after ICU admission did not differ between the groups (PMXHP: 29.1% vs. conventional: 29.0%, P = 0.98), and PMXHP therapy was not found to improve this outcome in a Cox regression analysis (hazard ratio = 1.16; 95% confidence interval, 0.81-1.64, P = 0.407). We conclude that PMX-based endotoxin adsorption within 24 hours from ICU admission was not associated with mortality among patients with septic shock due to GNB.
