Espasticidad tras ictus: ¿la edad es un factor de riesgo? Estudio observacional de la espasticidad en pacientes neurovasculares en una serie retrospectiva de dos centros

ObjectiveApproximately one third of patients who have suffered a stroke develop spasticity. Since clinical observations that spasticity in the elderly population is lower after stroke, and disagreement about risk factors between different authors, an analysis is performed on the variables that influence the development of spasticity.The objective of the study is to determine the how many factors influence spasticity outcome, and the prevalence of spasticity in patients who have suffered a stroke and require intensive rehabilitation treatment. MethodA retrospective assessment was carried out on a total of 554 patients from two neurorehabilitation centres. A record was made of sociodemographic data, aetiology, type and location of stroke, motor and sensory deficits, language and swallowing impairment, incontinence, cognitive and mood state. Spasticity levels at admission and at the third month were studied in 462 patients using the Ashworth scale. Multivariate regression analyses were used to assess the risk factors for spasticity present at the third month after stroke. ResultsThe mean age of the patients was 67.3 years, of which 67.1% were men, and with ischemic aetiology in 76.5%. On admission 31.4% of patients had spasticity, and this increased to 54.8% at the 3rd month. The absolute risk factor for spasticity was motor index (OR 1.04; 95% CI 1.03-1.05). When this factor was omitted, the variables with predictive ability were: age less than 75 years (OR 0.52; 95% CI 0.30-0.90), sensory impairment (OR 0.66; 95% CI 0.37-1.20), and lower Barthel index score (OR 1.02; 95% CI 1.01-1.03). There was no significant relationship for gender, physiopathological mechanism (ischaemic/haemorrhagic), stroke location, aphasia, or cognitive impairment. ConclusionThe prevalence of spasticity in stroke at third month of follow-up was 54.8%. Motor index is the independent predictor of spasticity. Patients younger than 75 years old, with sensory impairment and low Barthel index score are more likely to develop spasticity.

Risk factors and pathogenic microorganism characteristics for pneumonia in convalescent patients with stroke: A retrospective study of 380 patients from a rehabilitation hospital

Pneumonia is a major complication leading to death after stroke. The risk factors of pneumonia in convalescent patients who have experienced stroke remain poorly defined. To identify the risk factors of pneumonia, we applied logistic regression as a statistical method using SPSS23.0 statistical software, based on a sample of 380 patients. And statistical description method was used to analyze pathogens' characteristics and drug resistance. Ultimately, the obtained logistic model has statistical significance (χ2(13) = 91.560, P <0.0005). The sensitivity of the model is 41.7%, the specificity is 97.6%, the positive predictive value is 76.9%, and the negative predictive value is 89.8%. The Barthel index (BI) (OR=1.97, 95% CI: 1.01-3.87), basic lung diseases (OR=4.24, 95% CI: 1.02-17.61), trachea ventilation (OR=6.56, 95% CI: 1.18-36.34), feeding tube (OR=6.06, 95% CI: 2.59-14.18), and hypoproteinemia (OR=3.97, 95% CI: 1.56-10.10) were statistically significant (P<0.05). Among patients who have pneumonia, the proportion of gram-positive bacteria, gram-negative bacteria and fungal infection is 10.00%, 54.29%, 5.71% respectively. The study most frequently isolated Pseudomonas aeruginosa (18.57%), followed by Acinetobacter baumannii (10.00%,) and Klebsiella pneumoniae (10.00%). The drug resistance rate of Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae to different antibiotics ranged from 0.00-37.77%, 0.00-85.71% and 0.00-57.14%, respectively. The lower BI scores, basic lung diseases, trachea ventilation, tube feeding, and hypoproteinemia are independent risk factors of pneumonia among convalescent patients with stroke. The main pathogens that caused pneumonia were gram-negative bacteria, and such organisms have different degrees of resistance to drugs.

Direct Cost Related to Stroke: A Longitudinal Analysis of Survivors After Discharge From a Rehabilitation Hospital.

After discharge from a rehabilitation hospital, stroke survivors and their families may face considerable stroke-related direct costs. The total amount could be ascribed to the costs of formal and informal care and to the equipment or materials needed for care. This study aims to describe the direct costs incurred after a stroke by survivors during their first poststroke year and to analyze the basic predictors of these costs. Stroke survivors (N = 415) were enrolled for this study during discharge from rehabilitation hospitals (baseline) and interviewed at 3, 6, 9, and 12 months after discharge for a longitudinal study. The trend of the direct costs incurred during the follow-up (from T1 to T4; n = 239) was evaluated using a linear mixed-effects model. The mixed-effects model was used to identify the baseline predictors of the incurred direct costs from the stroke survivors. During the first year after discharge, stroke survivors spent approximately $3700 on stroke-related direct (ie, medical and nonmedical) costs. The highest direct costs occurred during the first 6 months, although there was not a significant change over time. The higher direct costs incurred were predicted by the linear effect of time, by the educational level (higher vs low), and by the lower Barthel Index score, whereas a higher perceived cost was predicted only by the linear effect of time and by the lower Barthel Index score. In the first poststroke year, direct costs have remained stable over time and can be predicted by the level of education and physical functioning. The identification of specific direct cost predictors would be helpful for developing more socially and economically tailored interventions for stroke survivors in their first year after their stroke.

Dysphagia is associated with poor physical function in patients with acute heart failure: a prospective cohort study.

Dysphagia is an important clinical problem in older adults with heart failure. Moreover, evidence is scarce regarding the prevalence and impact of dysphagia on physical function in these patients. This study examined the association of dysphagia and physical function in patients undergoing cardiac rehabilitation following heart failure. This prospective cohort study included consecutive 149 (mean age 78.6years, 72 women) inpatients in an acute-care hospital. Outcomes included the Food Intake Level Scale (FILS) and Barthel Index (BI) as indicators of dysphagia status and physical function, respectively. Multivariate analyses were used to determine whether FILS scores on admission and at the point of heart failure stabilization were associated with BI at discharge. Of the 149 patients, 14 (9.4%) had dysphagia at the time of stabilization of heart failure. Patients with dysphagia (FILS score < 7) were significantly older, more demented, exhibited lower muscle mass and strength, walked shorter distances, and had lower energy and protein intakes, longer length of stay, and lower BI scores (all, p < 0.05) compared to those without dysphagia. Multiple regression analyses showed that FILS score was independently associated with BI at discharge (β = 0.364, p < 0.001). Dysphagia was associated with declined physical function in patients undergoing cardiac rehabilitation following heart failure. Early detection and management of dysphagia can promote timely functional recovery in these patients.

Association between delirium, adverse clinical events and functional outcomes in older patients admitted to rehabilitation settings after a hip fracture: A multicenter retrospective cohort study.

The aim of the present study is to investigate how delirium and adverse clinical events (ACE) contribute independently and in combination to functional outcomes in older patients admitted to rehabilitation settings after a hip fracture. This is a multicenter retrospective cohort study of patients aged ≥65 years admitted after hip fracture surgical repair to three Italian rehabilitation units. Delirium on admission was evaluated with the Confusion Assessment Method. ACE during the rehabilitation stay were recorded, including infections (i.e. urinary tract infections, other infections), non-infectious ACE (i.e. cardiovascular events, respiratory failure, pulmonary embolism) and falls. A multivariable linear regression was used to evaluate the effect of ACE and delirium on functional outcome, adjusting for covariates determined a priori. A total of 519 patients were included in the study. The mean ± SD age was 82.9 ± 9.4 years. ACE occurred in 277 patients (53.4%), delirium alone was present in 19 patients (3.6%). Both conditions were present in 58 patients (11.2%). Compared with patients without delirium or ACE, those with ACE or delirium were more likely to have a worse functional outcome (-6.7 Barthel Index points [-11.6; -1.7]; P = 0.008; -13.2 [-25.6; -0.8]; P = 0.038) at discharge, and patients with both conditions had an even lower Barthel Index score (-18.6 Barthel Index points [-26.9; -10.3]; P < 0.001). ACE and delirium are very common in older patients admitted to rehabilitation settings after hip fracture, and frequently coexist. As both ACE and delirium could impact on functional outcome, alone and in combination, a clinical geriatric approach is necessary for this population to minimize risks.

Incidence and Risk Factors for Urinary Tract Infection in an Elder Home Care Population in Taiwan: A Retrospective Cohort Study.

Urinary tract infection (UTI) is a common infection worldwide. Numerous studies have demonstrated risk factors for UTI in facilities and communities. In this study, we aimed to identify risk factors for UTI in home care patients. Patients who received home care for at least three months in 2017 were included. A UTI episode was defined by admission for UTI treatment, and/or a visit to an outpatient department for UTI and receiving antibiotic prescription. A total of 598 patients aged 81.9 years were included. Overall 47% (281) had at least one UTI episode. After analysis, urinary catheter indwelling was the most important risk factor (odds ratio (OR), 3.21). Underlying diseases (coronary artery disease (CAD), chronic kidney disease (CKD), diabetes mellitus (DM)) were related to UTI with OR ranging from 1.46 to 1.79. Higher Alb (albumin) (OR 0.68) and Hb (hemoglobin) (OR 0.91) were inversely related to UTI. Polypharmacy (OR 1.84) and lower Barthel index scores (OR 1.62) were also related to UTI by different degrees. In conclusion, apart from the unmodifiable factors, avoiding prolonged urinary catheter placement, unnecessary prescriptions, and keeping good nutritional status may help to prevent UTI in home care patients.

Effect of Interventional Therapy on IL-1β, IL-6, and Neutrophil-Lymphocyte Ratio (NLR) Levels and Outcomes in Patients with Ischemic Cerebrovascular Disease.

BackgroundThis study investigated the clinical effect of interventional therapy in ischemic cerebrovascular disease (ICD).Material/MethodsA retrospective analysis was performed on 260 ICD patients who were divided into a control group (122 patients, conventional drug treatment) and an observation group (138 patients, interventional therapy plus conventional drug treatment). Enzyme-linked immunosorbent assay was used to examine the expression of IL-1β, IL-6, and NLR. Furthermore, neurological deficit scores and Barthel index scores as well as the correlation of IL-1β, IL-6 and NLR were examined in these 2 groups.ResultsThe expression of IL-1β, IL-6, and NLR significantly decreased in both groups after 1 week or 4 weeks of treatment compared with before treatment (P<0.05). Significant differences in neurological impairment scores were detected between these 2 groups after 4 weeks of treatment (P<0.05), and the control group showed higher neurological deficit scores than did the observation group (P<0.05). Barthel index scores were significantly higher after treatment than before treatment in the control and observation group (P<0.05), and the control group had lower Barthel index scores than did the observation group (P<0.05). Pearson correlation analysis showed that IL-1β, IL-6, and NLR expression were positively correlated in ICD patients (P<0.05).ConclusionsInterventional surgery combined with conventional drug therapy can reduce serum IL-1β and IL-6 levels, decrease neurological impairment, and improve the quality of life of patients. The combined treatment group showed better outcomes than did the group that received the drug alone; therefore, combined therapy is suitable for promoting better clinical outcomes.

Impact of Body Mass Index on Activities of Daily Living in Inpatients with Acute Heart Failure.

To investigate the impact of body mass index on activities of daily living in inpatients with acute heart failure. A retrospective cohort study. A hospital-based database contains Diagnosis Procedure Combination survey data from 100 participating acute-care hospitals. 11,301 inpatients aged 20 year or older who were admitted to the participating hospitals with a diagnosis of acute heart failure. The Barthel Index score at discharge and hospital death. The number of patients with a body mass index of <18.5 kg/m2 (underweight), 18.5-22.9 kg/m2 (low-normal weight), 23.0-24.9 kg/m2 (high-normal weight), 25.0-29.9 kg/m2 (overweight), and ≥30.0 kg/m2 (obesity) were 1689 (15%), 4715 (42%), 1809 (16%), 2306 (20%), and 782 (7%), respectively. Median Barthel Index scores at admission and discharge were 65 and 100, respectively. Hospital death occurred in 101 (0.9%) patients. Lower body mass index was associated with lower Barthel Index score at discharge and higher mortality. Multivariable analysis adjusted for body mass index, age, sex, New York Heart Association classification, Barthel Index score at admission, the updated Charlson Comorbidity Index, length of hospital stay, number of drugs administered, and rehabilitation during hospitalization revealed that body mass index was independently associated with Barthel Index score at discharge (beta: 0.354; 95% confidence interval: 0.248-0.461) and hospital death (odds ratio: 0.926, 95% confidence interval: 0.877-0.978). Overweight and obese inpatients showed greater independence in activities of daily living at discharge and lower rates of mortality, indicating the obesity paradox. A combination of rehabilitation and improved nutrition seems to be important in underweight patients with acute heart failure.

Thiamine status in end-stage chronic kidney disease patients: a single-center study.

Reportedly, thiamine deficiency, resulting from malnutrition and long-term diuretic therapy, is observed in patients with chronic kidney disease (CKD). The risk of thiamine deficiency might be enhanced, especially in end-stage CKD patients. Here, we assessed thiamine status in incident dialysis patients. This study was a single-center cross-sectional study which included 288 consecutive patients initiated into dialysis between April 2013 and March 2017 at our hospital. Thiamine status was evaluated by high-performance liquid chromatography of whole blood samples. We evaluated the association between blood thiamine concentration and other clinical parameters. Of the 288 patients, 21 patients receiving thiamine supplementation at the time of dialysis initiation and 26 patients without blood thiamine measurements were excluded. In 30 patients (12.4%), blood thiamine concentration was lower than the lower limit of normal (21.3ng/mL; dotted line). Blood thiamine concentration correlated with age, body mass index, and Barthel index (BI) score (p = 0.008, 0.012 and 0.009, respectively). Stepwise multivariate regression analysis indicated that BI scores were independent risk factors for thiamine deficiency (β coefficients = 0.169, p = 0.013). The proportion of end-stage CKD patients with low blood thiamine concentration is high. Low physical function (low BI score) is an independent risk factor of thiamine deficiency. Clinicians should be aware of thiamine deficiency in end-stage CKD patients, especially those with low physical function.

Risk of malnutrition is associated with poor physical function in patients undergoing cardiac rehabilitation following heart failure.

Patients who experience heart failure are prone to malnutrition. The aim of this study was to determine the association between risk of malnutrition and physical function in patients undergoing cardiac rehabilitation following heart failure. A cross-sectional study was performed in consecutive patients hospitalised for cardiac rehabilitation following heart failure. Risk of malnutrition was evaluated using the Mini Nutritional Assessment-Short Form (MNA-SF). Physical function was evaluated using the Barthel index (BI). Univariate and multivariate analyses were used to determine whether nutritional status was associated with BI in these patients. The present study included 105 patients (mean age of 77.3 years, 56 men and 49 women) for analysis. The median (interquartile range) scores of the MNA-SF and BI were 11 (9-13) and 75 (45-90), respectively. Patients with high risk of malnutrition (MNA-SF score < 7) were significantly older, had a lower body mass index, exhibited lower muscle mass and strength, could walk shorter distances, and had lower BI scores (all P < 0.05). On multivariate analysis, the MNA-SF score was independently associated with BI (β = 0.409, P < 0.001) after adjusting for age, sex, muscle mass and strength, brain natriuretic peptide levels, ejection fraction of the left ventricle, and reason for admission. Risk of malnutrition is associated with physical function in patients undergoing cardiac rehabilitation following heart failure. Early detection of malnutrition and commencement of nutritional support may improve functional recovery in these patients.

Malnutrition is associated with low physical function in patients undergoing cardiac rehabilitation following heart failure

Patients who experience heart failure are prone to malnutrition. The aim of this study was to determine the impact of malnutrition on physical function in patients undergoing cardiac rehabilitation following heart failure. A cross-sectional study was performed in consecutive patients hospitalized for cardiac rehabilitation following heart failure. Nutritional status was evaluated using the Mini Nutritional Assessment–Short-Form (MNA-SF). Physical function was evaluated using the Barthel index (BI). Univariate and multivariate analyses were used to determine whether nutritional status was associated with BI in these patients. The present study included 105 patients (mean age of 77.3 years; 56 men and 49 women) for analysis. The median (interquartile range) scores of the MNA-SF and BI were 11 (9–13) and 75 (45–90), respectively. Patients with malnutrition (MNA-SF < 7) were significantly older, had lower body mass index, exhibited lower muscle mass and strength, could walk shorter distances, and had lower BI scores (all, P < 0.05). In multivariate analysis, the MNA-SF score was independently associated with BI (beta = 0.409, P < 0.001) after adjusting for age, sex, muscle mass and strength, brain natriuretic peptide levels, ejection fraction of the left ventricle, and main diseases. Nutritional status is associated with physical function in patients undergoing cardiac rehabilitation following heart failure. Early detection of malnutrition can help promote nutritional support to improve functional recovery in these patients.

Restarting antiplatelet therapy after spontaneous intracerebral hemorrhage: Functional outcomes.

To compare the functional outcomes and health-related quality of life metrics of restarting vs not restarting antiplatelet therapy (APT) in patients presenting with intracerebral hemorrhage (ICH) in the ERICH (Ethnic/Racial Variations of Intracerebral Hemorrhage) study. Adult patients aged 18 years and older who were on APT before ICH and were alive at hospital discharge were included. Patients were dichotomized based on whether or not APT was restarted after hospital discharge. The primary outcome was a modified Rankin Scale score of 0-2 at 90 days. Secondary outcomes were excellent outcome (modified Rankin Scale score 0-1), mortality, Barthel Index, and health status (EuroQol-5 dimensions [EQ-5D] and EQ-5D visual analog scale scores) at 90 days. The APT and no APT cohorts comprised 127 and 732 patients, respectively. Restarting APT was associated with lower rates of good functional outcome (36.5% vs 40.8%; p = 0.021) and lower Barthel Index scores at 90 days (p = 0.041). The 2 cohorts were then matched in a 1:1 ratio, and the matched cohorts each comprised 107 patients. No difference in primary outcome was observed between restarting vs not restarting APT (35.5% vs 43.9%; p = 0.105). There were also no differences between the secondary outcomes of the 2 cohorts. Restarting APT in patients with ICH of mild to moderate severity after acute hospitalization is not associated with worse functional outcomes or health-related quality of life at 90 days. In patients with significant cardiovascular risk factors who experience an ICH, restarting APT remains the decision of the treating practitioner.

Falls-Related EvEnts in the first year after StrokE in Ireland: Results of the multi-centre prospective FREESE cohort study.

Falls are common post-stroke adverse events. This study aimed to describe the first-year falls incidence, circumstances and consequences among persons discharged home after stroke in Ireland, and to examine the association between potential risk factors and recurrent falls. Patients with acute stroke and planned home-discharge were recruited consecutively from five hospitals. Variables recorded pre-discharge included: age, stroke severity, co-morbidities, fall history, prescribed medications, hemi-neglect, cognition and functional independence (Barthel index). Falls were recorded with monthly diaries, and 6 and 12-month interviews. The association of pre-discharge factors with recurrent falls (>1 fall) was examined using univariable logistic regression. A total of 128 participants (mean age = 68.6, SD = 13.3) were recruited; 110 completed the 12-month follow-up. The first-year falls incidence was 44.5% (95% CI = 35.1-53.6) with 25.6% falling repeatedly (95% CI = 18.5-34.4). Fallers experienced 1-18 falls (median = 2) and five reported fractures; 47% of fallers experienced at least one fall outdoors. Only 10% of recurrent fallers had bone health medication prescribed at discharge. Lower Barthel index scores (<75/100, RR = 4.38, 1.64-11.72) and psychotropic medication prescription (RR = 2.10, 1.13-3.91) were associated with recurrent falls. This study presents prospectively collected information about falls circumstances. It was not powered for multivariable analysis of risk factors. One-quarter of stroke survivors discharged to the community fall repeatedly and mostly indoors in the first year. Specific attention may be required for individuals with poor functional independence or those on psychotropic medication. Future falls-management research in this population should explore falls in younger individuals, outdoor as well as indoor falls and post-stroke bone health status.

C-Reactive Protein Can Be an Early Predictor of Poststroke Apathy in Acute Ischemic Stroke Patients

Apathy is a multidimensional syndrome referring to a primary lack of motivation that occurs frequently in survivors of stroke. Higher C-reactive protein (CRP) level was associated with higher apathy scores among Alzheimer disease cases. However, data on the relationship between CRP levels and apathy in patients with stroke are lacking. So, we hypothesized an association between CRP and poststroke apathy (PSA). Two hundred ninety-two consecutive patients with stroke were recruited within 7 days after stroke. Apathy symptoms were assessed at baseline and at 1, 3, and 6 months after stoke using the Apathy Evaluation Scale-Clinical (AES-C). Demographic and clinical information were obtained using the National Institutes of Health Stroke Scale (NIHSS) scores, Barthel Index (BI) scores, Mini-Mental State Examination (MMSE) scores, Hamilton Depression Scale (HAMD) scores, and Hamilton Anxiety Scale (HAMA) scores. CRP was measured at baseline. The presence and the location of infarcts were evaluated using magnetic resonance imaging. Apathy at baseline was significantly associated with body mass index (BMI), NIHSS, BI, MMSE, HAMD, and CRP (P < .05) upon admission. PSA at 6 months was significantly associated with elevated CRP concentrations, high AES-C score, and low BI score (P < .05) upon admission. The AES-C scores peaked 3 months after stroke, but then abated over 6 months. CRP, BMI, MMSE, depression, and disability are closely related to apathy during the acute stage of ischemic stroke. Lower BI scores, higher CRP concentrations, and apathy in acute stroke phase increased the risk of PSA at 6 months.

Haemostatic factors do not account for worse outcomes from ischaemic stroke in patients with higher C-reactive protein concentrations.

Background Although the role of microparticles was recently implicated in stroke pathophysiology, the association between microparticles and inflammation is still not fully understood. The aim of this cohort study of 66 patients was to assess a relation between haemostatic factors, C-reactive protein and clinical outcome of ischaemic stroke. Methods Plasma microparticles procoagulant activity, concentrations of tissue factor-bearing microparticles, tissue factor and tissue factor pathway inhibitor in ischaemic stroke patients were determined with enzyme-linked immunosorbent assays at the time of initial diagnosis, along with serum C-reactive protein concentrations. Patients were divided into two groups depending on their C-reactive protein concentrations (C-reactive protein <3 mg/L; n = 28 vs. C-reactive protein ≥3 mg/L; n = 38). The analysed clinical outcome measures included the National Institutes of Health Stroke Scale and the Barthel Index. Results The two C-reactive protein groups did not differ significantly in terms of microparticles procoagulant activities, tissue factor-bearing microparticles, tissue factor and tissue factor pathway inhibitor concentrations. A significant correlation was observed between tissue factor pathway inhibitor and National Institutes of Health Stroke Scale score at admission ( R = 0.3, P = 0.03). Patients with C-reactive protein ≥3 mg/L presented with significantly higher National Institutes of Health Stroke Scale scores (median, 9.00 vs. 5.50, P = 0.002) and lower Barthel Index scores (median, 20.00 vs. 65.00, P = 0.002) than individuals with C-reactive protein <3 mg/L. The C-reactive protein concentrations correlatedpositively with National Institutes of Health Stroke Scale scores ( R = 0.3, P = 0.02) and inversely with Barthel Index scores ( R = - 0.4, P = 0.002). Conclusions Altogether, these findings imply that haemostatic parameters (microparticles, tissue factor-bearing microparticles, tissue factor, tissue factor pathway inhibitor) do not account for elevated C-reactive protein concentrations in ischaemic stroke patients.

Prevalence of infections among residents of Residential Care Homes for the Elderly in Hong Kong.

A point prevalence study was conducted to study the epidemiology of common infections among residents in Residential Care Homes for the Elderly in Hong Kong and their associated factors. Residential Care Homes for the Elderly in Hong Kong were selected by stratified single-stage cluster random sampling. All residents aged 65 years or above from the recruited homes were surveyed. Infections were identified using standardised definitions. Demographic and health information-including medical history, immunisation record, antibiotic use, and activities of daily living (as measured by Barthel Index)-was collected by a survey team to determine any associated factors. Data were collected from 3857 residents in 46 Residential Care Homes for the Elderly from February to May 2014. A total of 105 residents had at least one type of infection based on the survey definition. The overall prevalence of all infections was 2.7% (95% confidence interval, 2.2%-3.4%). The three most common infections were of the respiratory tract (1.3%; 95% confidence interval, 0.9%-1.9%), skin and soft tissue (0.7%; 95% confidence interval, 0.5%-1.0%), and urinary tract (0.5%; 95% confidence interval, 0.3%-0.9%). Total dependence in activities of daily living, as indicated by low Barthel Index score of 0 to 20 (odds ratio=3.0; 95% confidence interval, 1.4-6.2), and presence of a wound or stoma (odds ratio=2.7; 95% confidence interval, 1.4-4.9) were significantly associated with presence of infection. This survey provides information about infections among residents in Residential Care Homes for the Elderly in the territory. Local data enable us to understand the burden of infections and formulate targeted measures for prevention.

Association of post stroke depression with social factors, insomnia, and neurological status in Chinese elderly population.

The purpose of this study was to investigate the association of post stroke depression (PSD) with social factors, insomnia, and neurological status among elderly Chinese patients with ischemic stroke. Six hundred and eight patients over 60years of age, who had suffered from a first episode of ischemic stroke within 7days, were enrolled into the study. They were divided into PSD and non-PSD groups according to the Self-rating Depression Scale (SDS) scores. The association of PSD with social factors, insomnia, and neurological status was analyzed using multivariable logistic regression analysis. Compared with the patients who did not develop PSD, those with PSD reported adverse life events more frequently, and more subjects with PSD lived alone, had left carotid artery infarction and cortical infarction (P<0.05), history of insomnia, and high National Institute of Health Stroke Scale (NIHSS) scores and low Barthel Index (BI) scores (P<0.01). The multivariable logistic regression analysis showed that the occurrence of PSD was associated with a history of insomnia (HR=1.59, 95% CI 1.12-2.36, P<0.01), NIHSS scores (HR=2.45, 95% CI 1.42-3.91, P<0.01) and BI scores (HR=2.56, 95% CI 1.39-4.25, P<0.01). Insomnia and the degree of neurological deficit were associated with PSD in an elderly population of Chinese people.

Elevation of troponin I in acute ischemic stroke.

Background. Cardiac morbidities account for 20% of deaths after ischemic stroke and is the second commonest cause of death in acute stroke population. Elevation of cardiac troponin has been regarded as a prognostic biomarker of poor outcome in patients with acute stroke.Methods. This retrospective study enrolled 871 patients with acute ischemic stroke from August 2010 to March 2015. Data included vital signs, laboratory parameters collected in the emergency department, and clinical features during hospitalization. National Institutes of Health Stroke Scale (NIHSS), Barthel index, and modified Rankin Scale (mRS) were used to assess stroke severity and outcome.Results. Elevated troponin I (TnI) > 0.01 µg/L was observed in 146 (16.8%) patients. Comparing to patients with normal TnI, patients with elevated TnI were older (median age 77.6 years vs. 73.8 years), had higher median heart rates (80 bpm vs. 78 bpm), higher median white blood cells (8.40 vs. 7.50 1,000/m3) and creatinine levels (1.40 mg/dL vs. 1.10 mg/dL), lower median hemoglobin (13.0 g/dL vs. 13.7 g/dL) and hematocrit (39% vs. 40%) levels, higher median NIHSS scores on admission (11 vs. 4) and at discharge (8 vs. 3), higher median mRS scores (4 vs3) but lower Barthel index scores (20 vs. 75) at discharge (p < 0.001). Multivariate analysis revealed that age ≥ 76 years (OR 2.25, CI [1.59–3.18]), heart rate ≥ 82 bpm (OR 1.47, CI [1.05–2.05]), evidence of clinical deterioration (OR 9.45, CI [4.27–20.94]), NIHSS score ≥ 12 on admission (OR 19.52, CI [9.59–39.73]), and abnormal TnI (OR 1.98, CI [1.18–3.33]) were associated with poor outcome. Significant factors for in-hospital mortality included male gender (OR 3.69, CI [1.45–9.44]), evidence of clinical deterioration (OR 10.78, CI [4.59–25.33]), NIHSS score ≥ 12 on admission (OR 8.08, CI [3.04–21.48]), and elevated TnI level (OR 5.59, CI [2.36–13.27]). C-statistics revealed that abnormal TnI improved the predictive power of both poor outcome and in-hospital mortality. Addition of TnI > 0.01 ug/L or TnI > 0.1 ug/L to the model-fitting significantly improved c-statistics for in-hospital mortality from 0.887 to 0.926 (p = 0.019) and 0.927 (p = 0.028), respectively.Discussion. Elevation of TnI during acute stroke is a strong independent predictor for both poor outcome and in-hospital mortality. Careful investigation of possible concomitant cardiac disorders is warranted for patients with abnormal troponin levels.

Correlation of apathy during the acute stage of stroke with serum homocysteine, glycated hemoglobin and functional disability

Objective To investigate whether apathy during the acute stage of stroke was related to glycated hemoglobin and homocysteine(Hcy) and functional disability, and to elucidate possible factors that are related to poststroke apathy (PSA). Methods Totally 298 patients with acute cerebral infarction who met the inclusion and exclusion criteria were recruited from the Fourth Affiliated Hospital of China Medical University. The control group of 298 volunteers was recruited from medical center in our hospital during the same period. The apathy scale (AS) was used to assess PSA within 2 weeks after stroke. Patients with an AS score≥14 points were defined as PSA, and the patients were divided into apathy group (A group) and non-apathy group (NA group) according to AS score. Modified Rankin Scale (mRS) was used to assess functional disability. Functional disability in daily living activities was assessed with the Barthel Index(BI). Serum levels of Hcy, glycated hemoglobin A1C (HbA1c), lipid series and fibrinogen of patients were determined. Results The prevalence of PSA in patients was significantly higher than the control group (P<0.01). In the case group, A group had an older age, higher mRS score, higher Hcy level, lower educational level, lower BI score, and lower HbA1C level than the NA group(P<0.05). In the A group, the mRS score was positively correlated with the AS score(B=1.508, P=0.003), serum Hcy level was positively correlated with the AS score(B=0.170, P=0.013), the HbA1C level was negatively correlated with the AS score(B=-0.872, P=0.031). Conclusions The serum Hcy level, HbA1C level and functional disability are closely related to apathy during the acute stage of ischemic stroke. Key words: Brain infarction; Mood disorders; Homocysteine/ME; Hemoglobin A, glycosylated/ME

Preinjury Factors that Influence the Outcome of Patients with Hip Fracture

Background: The question of whether patients with hip fracture can be discharged home or require hospital transfer for additional rehabilitation is critical. The same clinical pathway is not suitable for all patients. However, there are no clear indices for establishing the appropriate clinical pathway. To address this, we examined preinjury factors, including the Barthel index (BI), and performed logistic regression analysis to identify factors affecting the outcome (direct home discharge or hospital transfer) of patients with hip fracture. Materials and methods: Patients with hip fracture who underwent surgery at Yokohama City University hospital were consecutively enrolled, and clinical data were retrospectively reviewed. Intergroup (direct home discharge or hospital transfer) comparison was performed using Student’s t test (continuous variables) and Fisher’s exact test (categorical variables). Factors affecting outcome were determined by logistic regression analysis. Receiver operating characteristic (ROC) curve analysis was used to identify the cut-off level, sensitivity, and specificity of the identified factors. Results: The preinjury BI scores for patients discharged home directly were significantly higher (p 79 were difficult to discharge directly home and were more likely to be transferred to another hospital (95.6% sensitivity and 62.9% specificity). Conclusions: Low preinjury BI scores ( 79) indicate a requirement for a co-operative pathway between regional hospitals that ensures a smooth hospital transfer.
