The effects of respiratory muscle training on respiratory function and functional capacity in patients with early stroke: a meta-analysis. Eur Rev Aging Phys Act 2024; 21:4. [PMID: 38383309 PMCID: PMC10882726 DOI: 10.1186/s11556-024-00338-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Accepted: 02/10/2024] [Indexed: 02/23/2024] Open
Abstract
BACKGROUND Respiratory muscle training is a continuous and standardized training of respiratory muscles, but the evidence of the effects on early stroke patients is not clear. This meta-analysis aimed to investigate the effects of respiratory muscle training on respiratory function and functional capacity in patients with early stroke. METHODS PubMed, Embase, PEDro, ScienceDirect, AMED, CINAHL, and China National Knowledge Infrastructure databases were searched from inception to December 8, 2023 for articles about studies that 1) stroke patients with age ≥ 18 years old. Early stroke < 3 months at the time of diagnosis, 2) respiratory muscle training, including inspiratory and expiratory muscle training, 3) the following measurements are the outcomes: respiratory muscle strength, respiratory muscle endurance, pulmonary function testing, dyspnea fatigue score, and functional capacity, 4) randomized controlled trials. Studies that met the inclusion criteria were extracted data and appraised the methodological quality and risk of bias using the Physiotherapy Evidence Database scale and the Cochrane Risk of Bias tool by two independent reviewers. RevMan 5.4 with a random effect model was used for data synthesis and analysis. Mean differences (MD) or standard mean differences (SMD), and 95% confidence interval were calculated (95%CI). RESULTS Nine studies met inclusion criteria, recruiting 526 participants (mean age 61.6 years). Respiratory muscle training produced a statistically significant effect on improving maximal inspiratory pressure (MD = 10.93, 95%CI: 8.51-13.36), maximal expiratory pressure (MD = 9.01, 95%CI: 5.34-12.69), forced vital capacity (MD = 0.82, 95%CI: 0.54-1.10), peak expiratory flow (MD = 1.28, 95%CI: 0.94-1.63), forced expiratory volume in 1 s (MD = 1.36, 95%CI: 1.13-1.59), functional capacity (SMD = 0.51, 95%CI: 0.05-0.98) in patients with early stroke. Subgroup analysis showed that inspiratory muscle training combined with expiratory muscle training was beneficial to the recovery of maximal inspiratory pressure (MD = 9.78, 95%CI: 5.96-13.60), maximal expiratory pressure (MD = 11.62, 95%CI: 3.80-19.43), forced vital capacity (MD = 0.87, 95%CI: 0.47-1.27), peak expiratory flow (MD = 1.51, 95%CI: 1.22-1.80), forced expiratory volume in 1 s (MD = 0.76, 95%CI: 0.41-1.11), functional capacity (SMD = 0.61, 95%CI: 0.08-1.13), while inspiratory muscle training could improve maximal inspiratory pressure (MD = 11.60, 95%CI: 8.15-15.05), maximal expiratory pressure (MD = 7.06, 95%CI: 3.50-10.62), forced vital capacity (MD = 0.71, 95%CI: 0.21-1.21), peak expiratory flow (MD = 0.84, 95%CI: 0.37-1.31), forced expiratory volume in 1 s (MD = 0.40, 95%CI: 0.08-0.72). CONCLUSIONS This study provides good-quality evidence that respiratory muscle training is effective in improving respiratory muscle strength, pulmonary function, and functional capacity for patients with early stroke. Inspiratory muscle training combined with expiratory muscle training seems to promote functional recovery in patients with early stroke more than inspiratory muscle training alone.

PLoS One 2023; 18:e0289790. [PMID: 37561680 PMCID: PMC10414659 DOI: 10.1371/journal.pone.0289790] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Accepted: 07/26/2023] [Indexed: 08/12/2023] Open
Abstract
BACKGROUND Whether stroke patients treated at hospitals with better short-term outcome metrics have better long-term outcomes is unknown. We investigated whether treatment at US hospitals with better 30-day hospital-level stroke outcome metrics was associated with better 1-year outcomes, including reduced mortality and recurrent stroke, for patients after ischemic stroke. METHODS This cohort study included Medicare fee-for-service beneficiaries aged ≥65 years discharged alive from US hospitals with a principal diagnosis of ischemic stroke from 07/01/2015 to 12/31/2018. We categorized patients by the treating hospital's performance on the CMS hospital-specific 30-day risk-standardized all-cause mortality and readmission measures for ischemic stroke from 07/01/2012 to 06/30/2015: Low-Low (both CMS mortality and readmission rates for the hospital were <25th percentile of national rates), High-High (both >75th percentile), and Intermediate (all other hospitals). We balanced characteristics between hospital performance categories using stabilized inverse probability weights (IPW) based on patient demographic and clinical factors. We fit Cox models assessing patient risks of 1-year all-cause mortality and ischemic stroke recurrence across hospital performance categories, weighted by the IPW and accounting for competing risks. RESULTS There were 595,929 stroke patients (mean age 78.9±8.8 years, 54.4% women) discharged from 2,563 hospitals (134 Low-Low, 2288 Intermediate, 141 High-High). For Low-Low, Intermediate, and High-High hospitals, respectively, 1-year mortality rates were 23.8% (95% confidence interval [CI] 23.3%-24.3%), 25.2% (25.1%-25.3%), and 26.5% (26.1%-26.9%), and recurrence rates were 8.0% (7.6%-8.3%), 7.9% (7.8%-8.0%), and 8.0% (7.7%-8.3%). Compared with patients treated at High-High hospitals, those treated at Low-Low and Intermediate hospitals, respectively, had 15% (hazard ratio 0.85; 95% CI 0.82-0.87) and 9% (0.91; 0.89-0.93) lower risks of 1-year mortality but no difference in recurrence. CONCLUSIONS Ischemic stroke patients treated at hospitals with better CMS short-term outcome metrics had lower risks of post-discharge 1-year mortality, but similar recurrent stroke rates, compared with patients treated at other hospitals.

Abstract
BACKGROUND COVID-19 is associated with an increased risk of venous thromboembolism (VTE). This study examined the prevalence of VTE among acute ischaemic stroke (AIS) patients with and without a history of COVID-19. METHODS We identified AIS hospitalisations of Medicare fee-for-service (FFS) beneficiaries aged ≥65 years from 1 April 2020 to 31 March 2022. We compared the prevalence and adjusted prevalence ratio of VTE among AIS patients with and without a history of COVID-19. RESULTS Among 283 034 Medicare FFS beneficiaries with AIS hospitalisations, the prevalence of VTE was 4.51%, 2.96% and 2.61% among those with a history of hospitalised COVID-19, non-hospitalised COVID-19 and without COVID-19, respectively. As compared with patients without a history of COVID-19, the prevalence of VTE among patients with a history of hospitalised or non-hospitalised COVID-19 were 1.62 (95% CI 1.54 to 1.70) and 1.13 (95% CI 1.03 to 1.23) times greater, respectively. CONCLUSIONS There appeared to be a notably higher prevalence of VTE among Medicare beneficiaries with AIS accompanied by a current or prior COVID-19. Early recognition of coagulation abnormalities and appropriate interventions may help improve patients' clinical outcomes.

Abstract
BackgroundPatient's care bundle has been found to have a beneficial effect on refractory diseases, but the preventive effect of this strategy on stroke-associated pneumonia (SAP) remains unclear. The purpose of this meta-analysis was to determine the role of the patient's care bundle in the prevention of SAP.MethodsA systematic search was conducted in five electronic databases to identify randomized controlled trials (RCTs) published before January 31, 2022. The incidence of SAP and aspiration and the length of hospital stay were assessed. Random pair-wise meta-analysis was conducted using Review Manager 5.4, and trial sequential analysis (TSA) was also performed.ResultsTwenty eligible RCTs involving 1916 patients were included for data analysis. Pooled results suggested that patient's care bundle was associated with significantly lower incidence of SAP (risk ratio [RR], 0.37; 95% CI, 0.29–0.46; p < 0.001; I2 = 0%) and aspiration (RR, 0.23; 95% CI, 0.15–0.35; p < 0.001; I2 = 0%). Meanwhile, patient's care bundle also significantly shortened the length of hospital stay for general patients (mean difference [MD], −3.10; 95% CI, −3.83 to −2.37; p < 0.001; I2 = 16%) and the length of intensive care unit (ICU) stay for patients with severe stoke (MD, −4.85; 95% CI, −5.86−3.84; p < 0.001; I2 = 0%). Results of TSA confirmed that none of the findings could be significantly reversed by future studies.ConclusionsThe patient's care bundle effectively prevents the occurrence of SAP and aspiration and shortens the hospital stay of stroke patients. However, it is necessary to design more high-quality studies to further validate our findings and investigate their applicability in other geographical regions.

Abstract
Identification of individuals with ischemic stroke at particularly high risk of venous thromboembolism (VTE) is crucial for targeted thromboprophylaxis. To guide clinical decision-making and development of risk prediction models, increased knowledge on risk factors and biomarkers is needed. Therefore, we set out to identify risk factors and predictors for VTE in people with ischemic stroke by conducting a systematic review of the literature. Medline and Embase were searched from January 1990 and onwards. Studies investigating demographic, clinical, and/or laboratory factors for stroke-related VTE were considered. Two reviewers screened all retrieved records, independently and in duplicate. Risk of bias assessments were guided by a structured framework (PROSPERO-ID: CRD42020176361). Of 4674 identified records, 26 studies were included. Twenty-six demographic, clinical, and laboratory factors associated with increased risk of stroke-related VTE after multivariable adjustments were identified. The following factors were reported by ≥2 studies: prior VTE, cancer, prestroke disability, leg weakness, increasing lesion volume of the brain infarct, infection, low Barthel Index, increasing length of hospital stay, biochemical indices of dehydration, as well as elevated levels of D-dimer, C-reactive protein, and homocysteine. The majority of the studies were of poor quality with moderate or high risk of bias. In conclusion, this systematic review informs on several potential risk factors and predictors for VTE in people with ischemic stroke. To improve risk stratification and guide development of risk prediction models, further confirmation is needed because there were few high-quality studies on each factor.

[PMID: 35095715 PMCID: PMC8792987 DOI: 10.3389/fneur.2021.747118] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Accepted: 12/14/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Stroke-associated pneumonia (SAP) is associated with poor prognosis after acute ischemic stroke (AIS). Purpose: This study aimed to describe the parameters of coagulation function and evaluate the association between the fibrinogen-to-albumin ratio (FAR) and SAP in patients with AIS. Patients and methods: A total of 932 consecutive patients with AIS were included. Coagulation parameters were measured at admission. All patients were classified into two groups according to the optimal cutoff FAR point at which the sum of the specificity and sensitivity was highest. Propensity score matching (PSM) was performed to balance potential confounding factors. Univariate and multivariate logistic regression analyses were applied to identify predictors of SAP. Results: A total of 100 (10.7%) patients were diagnosed with SAP. The data showed that fibrinogen, FAR, and D-dimer, prothrombin time (PT), activated partial thromboplastin time (aPTT) were higher in patients with SAP, while albumin was much lower. Patients with SAP showed a significantly increased FAR when compared with non-SAP (P < 0.001). Patients were assigned to groups of high FAR (≥0.0977) and low FAR (<0.0977) based on the optimal cut-off value. Propensity score matching analysis further confirmed the association between FAR and SAP. After adjusting for confounding and risk factors, multivariate regression analysis showed that the high FAR (≥0.0977) was an independent variable predicting the occurrence of SAP (odds ratio =2.830, 95% CI = 1.654–4.840, P < 0.001). In addition, the FAR was higher in the severe pneumonia group when it was assessed by pneumonia severity index (P = 0.008). Conclusions: High FAR is an independent potential risk factor of SAP, which can help clinicians identify high-risk patients with SAP after AIS.

Abstract
OBJECTIVE To evaluate the effects of respiratory muscle training in a population of stroke patients. DATA SOURCES The following databases were searched for clinical trials through December 2019: PubMed, EMBASE, Cochrane Library, CINAHL, and China National Knowledge Infrastructure. STUDY SELECTION Randomized controlled trials (N=9) published in English met the inclusion criteria. DATA EXTRACTION Data were extracted and assessed for accuracy by 2 reviewers. Any disagreements were resolved after discussions with an independent third reviewer. The quality of the included randomized controlled trials was assessed using the Cochrane bias tool. DATA SYNTHESIS The meta-analysis showed increased maximal inspiratory pressure (standardized mean difference [SMD], 0.88; 95% confidence interval [CI], 0.62-1.15; P<.001; 12-wk follow-up period: SMD, 0.94; 95% CI, 0.42-1.45; P<.001), maximal expiratory pressure (SMD, 0.83; 95% CI, 0.15-1.52; P=.017; 12-wk follow-up period: SMD, 0.99; 95% CI, 0.47-1.51; P<.001), forced expiratory volume in 1 second (SMD, 1.41; 95% CI, 0.57-2.24; P=.001), forced vital capacity (SMD, 1.36; 95% CI, 0.55-2.16; P<.001), peak expiratory flow (SMD, 0.74; 95% CI, 0.16-1.32; P=.013), 6-minute walk test (SMD, 0.67; 95% CI, 0.11-1.23; P=.020), and decreased respiratory complications (odds ratio, 0.55; 95% CI, 0.30-1.00; P=.050) compared with no respiratory intervention or a sham intervention. CONCLUSIONS Respiratory muscle training improved poststroke muscle strength and the benefits were carried over for up to 12 weeks, including improved lung function, walking capacity, and a reduced risk of respiratory impediments.

Abstract
OBJECTIVE Stroke is the leading cause of death and disability in China. Chinese medicine integrated with conventional medicine is now widely used in the prevention and treatment of stroke. A clinical practice guideline for the application of integrative medicine in stroke is urgently needed. METHODS This guideline was developed following the methodology and procedures recommended in the World Health Organization Handbook for Guideline Development and the Guideline Development Handbook for Diagnosis and Therapy of Integrative Medicine. The quality of evidence and strength of recommendations were evaluated using the GRADE approach. The guideline followed the RIGHT statement and AGREE II was consulted to ensure its quality. RESULTS A multidisciplinary working team was established. Eleven research questions from 15 clinical questions were identified by questionnaire surveys, face-to-face meetings, and analyzed by the working team. Fourteen recommendations regarding integrative medicine for ischemic stroke, hemorrhagic stroke, and complications of stroke were formulated from systematic reviews of the benefits, harms, cost-effectiveness, quality of evidence, the values and preferences of patients and their family members, feedback on proposed recommendations from medical practitioners from a variety of disciplines, and a face-to-face consensus meeting. CONCLUSIONS This guideline focuses on clinical treatments that are specific to integrative medicine for stroke and can be used at all levels in medical institutions and rehabilitation facilities. The end-users of the guideline are most likely to be medical practitioners, including Chinese herbal medicine specialists, acupuncturists, integrative medicine practitioners, physicians, physical therapists, and clinical pharmacists.

Arch Phys Med Rehabil 2020; 101:1170-1175. [PMID: 32113974 DOI: 10.1016/j.apmr.2020.01.018] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 01/13/2020] [Accepted: 01/15/2020] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To investigate the performance of the less affected upper limb in people with stroke compared with normative values. To examine less affected upper limb function in those whose prestroke dominant limb became paretic and those whose prestroke nondominant limb became paretic. DESIGN Cohort study of survivors of chronic stroke (7.2±6.7y post incident). SETTING The study was performed at a freestanding academic rehabilitation hospital. PARTICIPANTS Survivors of chronic stroke (N=40) with severe hand impairment (Chedoke-McMaster Stroke Assessment rating of 2-3 on Stage of Hand) participated in the study. In 20 participants the prestroke dominant hand (DH) was tested (nondominant hand [NH] affected by stroke), and in 20 participants the prestroke NH was tested (DH affected by stroke). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Jebsen-Taylor Hand Function Test. Data from survivors of stroke were compared with normative age- and sex-matched data from neurologically intact individuals. RESULTS When combined, DH and NH groups performed significantly worse on fine motor tasks with their nonparetic hand relative to normative data (P<.007 for all measures). Even the participants who continued to use their prestroke DH as their primary hand after the stroke demonstrated reduced fine motor skills compared with normative data. In contrast, grip strength was not significantly affected in either group of survivors of stroke (P>.140). CONCLUSIONS Survivors of stroke with severe impairment of the paretic limb continue to present significant upper extremity impairment in their nominally nonparetic limb even years after stroke. This phenomenon was observed regardless of whether the DH or NH hand was primarily affected. Because this group of survivors of stroke is especially dependent on the nonparetic limb for performing functional tasks, our results suggest that the nonparetic upper limb should be targeted for rehabilitation.

Prevalence, incidence, and risk factors of urinary tract infection among immobile inpatients in China: a prospective, multi-centre study. J Hosp Infect 2019; 104:538-544. [PMID: 31790744 DOI: 10.1016/j.jhin.2019.11.018] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 11/24/2019] [Accepted: 11/25/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND Immobile inpatients have a high risk of urinary tract infection (UTI). Additional epidemiological data regarding UTIs among immobile inpatients are needed. AIM To investigate the prevalence and incidence of, and risk factors for, UTIs among immobile patients in 25 hospitals throughout China. METHODS This was a national multi-centre cross-sectional investigation. We recruited six tertiary hospitals, 12 non-tertiary hospitals, and seven community hospitals. We obtained data regarding demographics, clinically related variables, and UTI-specific variables from immobile patients during their hospitalization. We performed univariate and multivariable analyses, and binary logistic regression analysis was used to identify risk factors. FINDINGS Among 23,985 immobile patients, 393 had a UTI. The prevalence and incidence of UTIs in hospitalized immobile patients was 1.64% (393/23 985) and 0.69 per 1000 patient-days, respectively. The infection rate of catheter-associated UTI was 2.25 per 1000 urinary catheter-days. We found that a greater number of bedridden days, longer length of hospital stay, being in a medical ward, the presence of an indwelling urethral catheter, prolonged duration of an indwelling catheter, use of glucocorticoids, female sex, diabetes mellitus, and older age were independent risk factors of UTI. CONCLUSION Immobile patients had similar risk factors for UTI as the general population, as well as some additional risk factors. Greater attention is needed in the management of UTIs among the population of immobile hospitalized patients.

Abstract
Background and purpose: Urinary tract infection (UTI) is one of the most common complications following stroke and has prognostic significance. UTI rates have been shown to vary between hospitals, but it is unclear whether this is due to case-mix differences or heterogeneities in care among hospitals. Methods: A prospective multi-center cohort study of acute stroke patients admitted to eight National Health Service (NHS) acute hospital trusts within the Anglia Stroke & Heart Clinical Network between 2009 and 2011 was conducted. We modeled the association between hospital (as a fixed-effect) and inpatient UTI using a multivariable logistic regression model, adjusting for established patient-level risk factors. We graphically and descriptively analyzed heterogeneities in hospital-level characteristics. Results: We included 2,241 stroke admissions in our analysis; 171 (7.6%) acquired UTI as an inpatient. UTI rates varied significantly between the eight hospitals, ranging from 3 to 11%. The hospital that had the lowest odds of UTI [odds ratio (OR) = 0.50 (95% confidence interval (CI) 0.22–.11)] in adjusted analysis, had the highest number of junior doctors and occupational therapists per five beds of all hospitals. The hospital with the highest adjusted UTI rate [OR=2.69 (1.56–4.64)] was tertiary, the largest and had the highest volume of stroke patients, lowest number of stroke unit beds per 100 admissions, and the highest number of hospital beds per CT scanner. Conclusions: There is hospital-level variation in post-stroke UTI. Our results suggest the potential influence of service characteristics independently of patient-level factors which may be amenable to be addressed to improve the ultimate stroke outcome.

Abstract
BACKGROUND Implementation of modern stroke unit care might have attenuated the negative effect of infections on stroke outcome. Our aim was to investigate changes in the occurrence of pneumonia and urinary infections diagnosed after admission to experienced Polish stroke center between 1995 and 2015, and their association with hospital mortality. MATERIALS AND METHODS This is a retrospective registry-based analysis of consecutive patients with acute stroke from highly urbanized area (Warsaw, Poland) in years 1995-2015. A total of 5174 patients were divided to 4 time periods: 1995-2000 (n = 883), 2001-2006 (n = 1567), 2006-2010 (n = 1539), and 2011-2015 (n = 1183). Odds ratios (ORs) for hospital death were calculated after adjustment for age, congestive heart failure, preexisting disability, stroke type, and baseline neurological deficit, separately in years 1995-2015, 1995-2000, and 2011-2015. RESULTS Over time there was a significant decrease in the proportion of patients diagnosed with pneumonia (20%, 19%, 9%, and 15%, respectively) or urinary tract infection (29%, 21%, 24%, and 18%, respectively) and in the proportion of patients having body temperature of 38.0°C or higher at least once within first 7 days of hospital stay (20%, 20%, 13%, and 13%, respectively), without significant change in the use of antibiotics (range 35%-37%). Hospital mortality was strongly predicted by pneumonia (OR 3.6-4.2) and fever (OR 2.7-4.7) but not urinary infections. CONCLUSIONS Over the last 2 decades there was a decrease in the proportion of patients with acute stroke diagnosed with pneumonia or urinary tract infection during stroke unit stay. Hospital death was strongly predicted by pneumonia and fever but no by urinary infections.

Abstract
BACKGROUND Early dysphagia screening and appropriate management are recommended by current guidelines to reduce complications and case fatality in acute stroke. However, data on the potential benefit of changes in dysphagia care on patient outcome are limited. Our objective was to assess the degree of implementation of dysphagia guidelines and determine the impact of modifications in dysphagia screening and treatment practices on disease complications and outcome in stroke patients over time. METHODS In this prospective register-based study ("Stroke Register of Northwestern Germany"), all adult stroke patients admitted to 157 participating hospitals between January, 2008 and December, 2015 were included (n = 674,423). Dysphagia incidence upon admission, the proportion of patients receiving a standardized swallowing screening, and the percentage of dysphagic patients being referred to a speech language therapist (SLT) for treatment were obtained per year. Pneumonia rate, modified Rankin Scale (mRS) at discharge, and in-hospital mortality were compared between groups of dysphagic vs. non-dysphagic patients over time. RESULTS Screening proportions continuously increased from 47.2% in 2008 to 86.6% in 2015. But the proportion diagnosed with dysphagia remained stable with about 19%. The number of dysphagic patients receiving SLT treatment grew from 81.6 up to 87.0%. Pneumonia incidence was higher in dysphagic stroke cases (adjusted OR 5.4 [5.2-5.5], p < 0.001), accompanied by a worse mRS at discharge (adjusted OR for mRS ≥3: 3.1 [3.0-3.1], p < 0.001) and higher mortality (adjusted OR 3.1 [3.0-3.2], p < 0.001). The order of magnitude of these end points did not change over time. CONCLUSION Although advances have been made in dysphagia care, prevalent screening and treatment practices remain insufficient to reduce pneumonia rate, improve functional outcome, and decrease case fatality in dysphagic stroke patients. More research is urgently needed to develop more effective swallowing therapies.

Abstract
BACKGROUND Although rehabilitation therapy is commonly provided after stroke, many patients do not derive maximal benefit because of access, cost, and compliance. A telerehabilitation-based program may overcome these barriers. We designed, then evaluated a home-based telerehabilitation system in patients with chronic hemiparetic stroke. METHODS Patients were 3 to 24 months poststroke with stable arm motor deficits. Each received 28 days of telerehabilitation using a system delivered to their home. Each day consisted of 1 structured hour focused on individualized exercises and games, stroke education, and an hour of free play. RESULTS Enrollees (n = 12) had baseline Fugl-Meyer (FM) scores of 39 ± 12 (mean ± SD). Compliance was excellent: participants engaged in therapy on 329/336 (97.9%) assigned days. Arm repetitions across the 28 days averaged 24,607 ± 9934 per participant. Arm motor status showed significant gains (FM change 4.8 ± 3.8 points, P = .0015), with half of the participants exceeding the minimal clinically important difference. Although scores on tests of computer literacy declined with age ( r = -0.92; P < .0001), neither the motor gains nor the amount of system use varied with computer literacy. Daily stroke education via the telerehabilitation system was associated with a 39% increase in stroke prevention knowledge ( P = .0007). Depression scores obtained in person correlated with scores obtained via the telerehabilitation system 16 days later ( r = 0.88; P = .0001). In-person blood pressure values closely matched those obtained via this system ( r = 0.99; P < .0001). CONCLUSIONS This home-based system was effective in providing telerehabilitation, education, and secondary stroke prevention to participants. Use of a computer-based interface offers many opportunities to monitor and improve the health of patients after stroke.

Abstract
BACKGROUND Medical complications often worsen the prognosis after stroke. Our aim was to investigate the association between particular noninfectious complications and hospital mortality of acute stroke patients admitted to an urban Polish stroke center, and changes in their occurrence from 1995 to 2015. METHODS This is a retrospective analysis of 5174 consecutive patients admitted for acute ischemic stroke or cerebral hemorrhage to a Polish urban stroke center between 1995 and 2015. The occurrence of complications was reported for years 1995-2000 (n=883), 2001-2006 (n=1567), 2006-2010 (n=1539) and 2011-2015 (n=1183). Odds ratios (OR) with 95% confidence interval (95% CI) for stroke unit death were calculated after adjustment for age, congestive heart failure (CHF), pre-existing disability, stroke type and baseline neurological deficit in three different time periods. RESULTS Over time there was a significant decrease in the occurrence of myocardial infarction (MI) (2.2%, 1.4%, 1.0% and 0.3%, respectively), exacerbated CHF (4.6%, 5.1%, 2.6% and 2.0%) and deep vein thrombosis (DVT) (4.6%, 2.7%, 1.2% and 1.1%). Adjusted odds for stroke unit death were increased by myocardial infarction (MI) (OR 17.5, 95% CI: 8.5-35.7), exacerbated CHF (OR 15.0, 95% CI: 9.8-23.0), pulmonary embolism (PE) (OR 11.5, 95% CI: 6.1-21.6), gastrointestinal bleeding (OR 9.2, 95% CI: 4.4-18.9) and recurrent stroke (OR 5.4, 95% CI: 3.1-9.3). CONCLUSIONS Over the last two decades Polish urban stroke units may have achieved a significant reduction of the occurrence of some noninfectious complications (i.e. MI, exacerbated CHF and DVT). However, the list of conditions associated with stroke unit mortality includes not only MI and exacerbated CHF but also PE, gastrointestinal bleeding and recurrent stroke.

Abstract
Objective Infections are frequent after stroke and lead to increased mortality and neurological disability. Antibiotic prophylaxis has potential of decreasing the risk of infections and mortality and improving poor functional outcome. Several studies evaluated antibiotic prophylaxis for infections in acute stroke patients have generated conflicting results. The systematic review of randomized clinical trials (RCTs) aimed at comprehensively assessing the evidence of antibiotic prophylaxis for the treatment of acute stroke patients. Materials and Methods PubMed, EMBASE, the Cochrane library and the reference lists of eligible articles were searched to identify all potential studies. We included the studies that investigated the efficacy and safety of antibiotic prophylaxis for the treatment of acute stroke patients. The primary outcome included mortality and infection rate. The secondary outcomes included poor functional outcome and adverse events. Results Seven trials randomizing 4,261 patients were included. Pooled analyses showed that antibiotic prophylaxis did not improve the mortality (risk ratio (RR) = 1.03, 95% confidence interval (CI) 0.84 to 1.26, p = 0.78, I2 = 25%) and poor functional outcome (RR = 0.93, 95% CI 0.80 to 1.08, p = 0.32, I2 = 80%), but reduced the incidence of infection (RR = 0.67, 95% CI 0.53 to 0.84, p = 0.0007, I2 = 49%). No major side effects were reported. Sensitivity analyses confirmed the results of infection rate and poor functional outcome. Conclusions Antibiotic prophylaxis can be used to treat the infectious events of acute stroke patients although it has no potential of decreased mortality and improved functional outcome.

Abstract
BACKGROUND Acupuncture is considered a complementary and alternative medicine in many countries. The purpose of this study was to report the pattern of acupuncture use and associated factors in patients with stroke. METHODS We used claims data from Taiwan's National Health Insurance Research Database and identified 285001 new-onset stroke patients in 2000-2008 from 23 million people allover Taiwan. The use of acupuncture treatment after stroke within one year was identified. We compared sociodemographics, coexisting medical conditions, and stroke characteristics between stroke patients who did and did not receive acupuncture treatment. RESULTS The use of acupuncture in stroke patients increased from 2000 to 2008. Female gender, younger age, white-collar employee status, higher income, and residence in areas with more traditional Chinese medicine (TCM) physicians were factors associated with acupuncture use in stroke patients. Ischemic stroke (odds ratio [OR] 1.21, 95 % confidence interval [CI] 1.15-1.28), having no renal dialysis (OR 2.76, 95 % CI 2.45-3.13), receiving rehabilitation (OR 3.20, 95 % CI 3.13-3.27) and longer hospitalization (OR 1.23, 95 % CI 1.19-1.27) were also associated with acupuncture use. Stroke patients using rehabilitation services were more likely to have more acupuncture visits and a higher expenditure on acupuncture compared with stroke patients who did not receive rehabilitation services. CONCLUSIONS The application of acupuncture in stroke patients is well accepted and increasing in Taiwan. The use of acupuncture in stroke patients is associated with sociodemographic factors and clinical characteristics.

Abstract
OBJECTIVE To investigate the risk of epilepsy in stroke patients receiving and not receiving acupuncture treatment. DESIGN Retrospective cohort study. SETTING This study was based on Taiwan's National Health Insurance Research Database that included information on stroke patients hospitalised between 1 January 2000 and 31 December 2004. PARTICIPANTS We identified 42 040 patients hospitalised with newly diagnosed stroke who were aged 20 years and above. PRIMARY AND SECONDARY OUTCOME MEASURES We compared incident epilepsy during the follow-up period until the end of 2009 in stroke patients who were and were not receiving acupuncture. The adjusted HRs and 95% CIs of epilepsy associated with acupuncture were calculated using multivariate Cox proportional hazard regression. RESULTS Stroke patients who received acupuncture treatment (9.8 per 1000 person-years) experienced a reduced incidence of epilepsy compared to those who did not receive acupuncture treatment (11.5 per 1000 person-years), with an HR of 0.74 (95% CI 0.68 to 0.80) after adjustment for sociodemographic factors and coexisting medical conditions. Acupuncture treatment was associated with a decreased risk of epilepsy, particularly among stroke patients aged 20-69 years. The log-rank test probability curve indicated that stroke patients receiving acupuncture treatment had a reduced probability of epilepsy compared with individuals who did not receive acupuncture treatment during the follow-up period (p<0.0001). CONCLUSIONS Stroke patients who received acupuncture treatment had a reduced risk of epilepsy compared with those not receiving acupuncture treatment. However, the protective effects associated with acupuncture treatment require further validation in prospective cohort studies.

The Effect of Photoluminescence of Bioceramic Irradiation on Middle Cerebral Arterial Occlusion in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:7230962. [PMID: 27375765 PMCID: PMC4914731 DOI: 10.1155/2016/7230962] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Revised: 04/12/2016] [Accepted: 04/27/2016] [Indexed: 11/28/2022]
Abstract
The purpose of this study is to determine the possible effect of photoluminescence of bioceramic (PLB) on ischemic cerebral infarction (stroke), by using an animal model of transient middle cerebral artery occlusion (MCAO). Sprague-Dawley rats were used to induce MCAO to block the origin of the left MCAO; three months later, the positive chronic stroke rats were selected by running tunnel maze; the MCAO rats with significant chronic stroke and neurological defects were used for treadmill experiments with varying speed settings to test their capability for restoration after muscular fatigue under conditions of with and without PLB irradiation. As a result, PLB irradiation could improve exercise completion rate and average running speed during slow and fast treadmill settings. After PLB irradiation, the selected MCAO rats successfully completed all the second-round treadmill exercises at the maximum speed setting, and they had better restoration from muscular fatigue. An in vitro cell study on astrocytes of rats by bioceramic irradiation further demonstrated increased intracellular nitric oxide. To explain these results, we suggest that cortical brain stimulation of microcirculation and enhancement of peripheral muscular activity are the main causes of the improved exercise performance in MCAO rats by PLB.

Abstract
Post-stroke dysphagia (a difficulty in swallowing after a stroke) is a common and expensive complication of acute stroke and is associated with increased mortality, morbidity, and institutionalization due in part to aspiration, pneumonia, and malnutrition. Although most patients recover swallowing spontaneously, a significant minority still have dysphagia at six months. Although multiple advances have been made in the hyperacute treatment of stroke and secondary prevention, the management of dysphagia post-stroke remains a neglected area of research, and its optimal management, including diagnosis, investigation and treatment, have still to be defined.

Abstract
Background Pneumonia frequently complicates stroke and has a major impact on outcome. We derived and internally validated a simple clinical risk score for predicting stroke‐associated pneumonia (SAP), and compared the performance with an existing score (A2DS2). Methods and Results We extracted data for patients with ischemic stroke or intracerebral hemorrhage from the Sentinel Stroke National Audit Programme multicenter UK registry. The data were randomly allocated into derivation (n=11 551) and validation (n=11 648) samples. A multivariable logistic regression model was fitted to the derivation data to predict SAP in the first 7 days of admission. The characteristics of the score were evaluated using receiver operating characteristics (discrimination) and by plotting predicted versus observed SAP frequency in deciles of risk (calibration). Prevalence of SAP was 6.7% overall. The final 22‐point score (ISAN: prestroke Independence [modified Rankin scale], Sex, Age, National Institutes of Health Stroke Scale) exhibited good discrimination in the ischemic stroke derivation (C‐statistic 0.79; 95% CI 0.77 to 0.81) and validation (C‐statistic 0.78; 95% CI 0.76 to 0.80) samples. It was well calibrated in ischemic stroke and was further classified into meaningful risk groups (low 0 to 5, medium 6 to 10, high 11 to 14, and very high ≥15) associated with SAP frequencies of 1.6%, 4.9%, 12.6%, and 26.4%, respectively, in the validation sample. Discrimination for both scores was similar, although they performed less well in the intracerebral hemorrhage patients with an apparent ceiling effect. Conclusions The ISAN score is a simple tool for predicting SAP in clinical practice. External validation is required in ischemic and hemorrhagic stroke cohorts.

Abstract
The safety, tolerability, and efficacy data for antipsychotic drugs used in the acute phase of stroke are limited. The primary aim of this study was to examine the effectiveness and safety of typical and atypical antipsychotics on acute ischemic stroke mortality.This observational study was conducted in a retrospective cohort of patients selected from the 2010-2011 National Health Research Institute database in Taiwan. Patients were tracked for 1 month from the time of their first hospitalization for acute ischemic stroke. A nested case-control analysis was used to estimate the odds ratio (OR) of 30-day mortality associated with antipsychotic drug, adjusted for age, gender, disease severity, and comorbidities.The study cohort included 47,225 subjects with ischemic stroke, including 9445 mortality cases and 37,780 matched controls. After adjustment for the covariates, antipsychotics users before ischemic stroke are associated with a 73% decrease in the rate of mortality (OR 0.27; 95% CI 0.23-0.31). After ischemic stroke, the use of antipsychotics is associated with 87% decrease in the rate of mortality (OR 0.13; 95% CI 0.1-0.16). The users of conventional antipsychotics are associated with a 78% decrease in the rate of mortality (OR 0.22; 95% CI 0.18-0.26). The users of atypical antipsychotics are also associated with a 86% decrease in the rate of mortality (OR 0.14; 95% CI 0.12-0.17).We found that 1-month mortality among acute stroke patients treated with antipsychotics is significantly lower. The benefit on lower mortality was found not only among ischemic stroke patients who had received antipsychotics previously but also among patients who start antipsychotics after their stroke.

Abstract
BACKGROUND AND PURPOSE The A2DS2 score was recently developed from the Berlin Stroke Registry for predicting in-hospital pneumonia after acute ischemic stroke and performed well in an external validation in the North-west Germany Stroke Registry. It could be a useful tool for risk stratification in clinical practice or stroke trials. We aimed to prospectively validate the predictive value of A2DS2 score in a Chinese stroke population. METHODS The prognostic model was used to predict stroke-associated pneumonia (SAP) from Henan Province Stroke Registry (HNSR) in which data were prospectively collected. The receiver-operating characteristic curves were plotted, and the C statistics were calculated to assess the discrimination ability. The Hosmer-Lemeshow goodness-of-fit test and the plot of observed versus predicted SAP risk were used to assess model calibration. RESULTS Among 1142 eligible patients, the overall in-hospital SAP was 18.8%, which ranged from 9.0% in patients with lower A2DS2 scores (0-4) to 65.0% in those with higher scores of 5 to 10 (P for trend <0.001). The C statistic was 0.836 (95% confidence interval, 0.803-0.868) through the A2DS2 score, suggesting excellent discrimination in the HNSR. The A2DS2 score also showed excellent calibration (Cox and Snell R2 = 0.243) in the external validation sample from the HNSR. CONCLUSIONS The A2DS2 score could reliably predict in-hospital SAP in Chinese stroke patients. It might be helpful for the assessment of increased risk monitoring and prophylactic treatment in identified high-risk patients for SAP in clinical routine.

Abstract
BACKGROUND After stroke, pneumonia is a relevant medical complication that can be precipitated by aspiration of saliva, liquids, or solid food. Swallowing difficulty and aspiration occur in a significant proportion of stroke survivors. Cough, an important mechanism protecting the lungs from inhaled materials, can be impaired in stroke survivors, and the likely cause for this impairment is central weakness of the respiratory musculature. Thus, respiratory muscle training in acute stroke may be useful in the recovery of respiratory muscle and cough function, and may thereby reduce the risk of pneumonia. The present study is a pilot study, aimed at investigating the validity and feasibility of this approach by exploring effect size, safety, and patient acceptability of the intervention. METHODS/DESIGN Adults with moderate to severe stroke impairment (National Institutes of Health Stroke Scale (NIHSS) score 5 to 25 at the time of admission) are recruited within 2 weeks of stroke onset. Participants must be able to perform voluntary respiratory maneuvers. Excluded are patients with increased intracranial pressure, uncontrolled hypertension, neuromuscular conditions other than stroke, medical history of asthma or chronic obstructive pulmonary disease, and recent cardiac events. Participants are randomized to receive inspiratory, expiratory, or sham respiratory training over a 4-week period, by using commercially available threshold resistance devices. Participants and caregivers, but not study investigators, are blind to treatment allocation. All participants receive medical care and stroke rehabilitation according to the usual standard of care. The following assessments are conducted at baseline, 4 weeks, and 12 weeks: Voluntary and reflex cough flow measurements, forced spirometry, respiratory muscle strength tests, incidence of pneumonia, assessments of safety parameters, and self-reported activity of daily living. The primary outcome is peak expiratory cough flow of voluntary cough, a parameter indicating the effectiveness of cough. Secondary outcomes are incidence of pneumonia, peak expiratory cough flow of reflex cough, and maximum inspiratory and expiratory mouth pressures. DISCUSSION Various novel pharmacologic and nonpharmacologic approaches for preventing stroke-associated pneumonia are currently being researched. This study investigates a novel strategy based on an exercise intervention for cough rehabilitation. TRIAL REGISTRATION Current Controlled Trials ISRCTN40298220.

Abstract
Patients with neurologic disease are at high risk of venous thromboembolism (VTE) because of relative immobility. They are also at increased risk due to the presence of a hypercoagulable state. Patients with spinal cord injuries, brain tumors, and strokes are at particularly high risk and extra vigilance is needed in these patients. Because VTE is very common in hospitalized neurologic and neurosurgical patients, mechanical thromboprophylaxis is indicated in virtually all patients. Pharmacologic prophylaxis with either subcutaneous heparin or low molecular heparinoids should be given to all high-risk neurologic and neurosurgical patients provided there are no major contraindications. The major concern would be a risk of bleeding but in some patients alternate drugs must be considered given the risk of thrombosis (i.e., in the context of heparin-induced thrombocytopenia). The immediate or long-term treatment of full dose anticoagulation for VTE may not be appropriate in all patients as VTE therapy represents a balance between the risks of bleeding related to anticoagulant therapy versus the risk of recurrent events. An inferior vena cava (IVC) filter is another option in these patients but may not necessarily be the best choice for most neurologic patients. Given the high risk of VTE in patients with neurologic diseases, early recognition by clinicians of the signs and symptoms of VTE is essential.

Abstract
Background Limited information is available on the frequency of pulmonary embolism (PE) in patients with an acute ischemic stroke (AIS). We evaluated clinical characteristics, predisposing factors, and outcomes in AIS patients with PE. Methods and Results We included all AIS patients admitted to participating institutions in the Registry of the Canadian Stroke Network. Clinically PE was documented by a physician and confirmed by computed tomography pulmonary angiography within 30 days of the stroke case index. The primary outcome was death or disability at discharge. Secondary outcomes included disposition, length of hospital stay, mortality at 3 months and 1 year. Among 11 287 patients with AIS, PE was found in 89 (0.78%) patients. History of cancer, deep vein thrombosis (DVT)/PE, and DVT during the hospitalization were associated with PE. PE was associated with higher risk of death at 30 days (25.8% versus 13.6%; P<0.001), at 1 year (47.2% versus 24.6%; P<0.001), and disability at discharge (85.4% versus 63.6%; P<0.001). Mean length of stay was longer in stroke patients with PE (36 versus 16 days; P=0.001). After adjusting for age, sex, and stroke severity, PE remained associated with lower survival at 30 days and 1 year, and death or disability at discharge (OR 3.02; 95% CI 1.56 to 5.83). Conclusions In this large cohort study, PE occurred in nearly 1% of AIS patients. PE was more common in patients with severe stroke, history of cancer, previous DVT/PE or acute DVT and associated with lower short‐ and long‐term survival, greater disability, and longer length of stay.

Abstract
BACKGROUND AND PURPOSE Medical complications are common among patients with stroke. However, little is known about the potential interrelationship among them. In the present study, we aimed to investigate the association between common in-hospital medical complications after acute ischemic stroke (AIS) and spontaneous intracerebral hemorrhage (ICH). METHODS We analyzed patients enrolled in the China National Stroke Registry from 2007 to 2008. The occurrence of 11 common stroke-associated medical complications during acute hospitalization was prospectively registered. Multivariable analysis using generalized estimation equation was performed to assess association between medical complications in AIS and ICH cohort, respectively. RESULTS A total of 14 702 patients with AIS and 5221 patients with ICH were enrolled. The median age was 65 years (interquartile range, 55-74 years), and 38.1% were female. The median length of hospital stay was 14 days (interquartile range, 10-20 days) for AIS and 18 days (interquartile range, 11-26 days) for ICH. Pneumonia was the most common medical complication after AIS (11.4%) and ICH (16.8%). In the AIS cohort, after adjusting for potential confounders, pneumonia was significantly associated with development of gastrointestinal bleeding (adjusted odds ratio [OR], 8.35; 95% confidence interval [CI], 6.27-11.1; P<0.001), decubitus ulcer (adjusted OR, 5.31; 95% CI, 3.39-8.31; P<0.001), deep vein thrombosis (adjusted OR, 4.27; 95% CI, 2.41-7.59; P<0.001), epileptic seizure (adjusted OR, 3.96; 95% CI, 2.67-5.88; P<0.001), urinary tract infection (adjusted OR, 3.34; 95% CI, 2.73-4.10; P<0.001), atrial fibrillation/flutter (adjusted OR, 3.17; 95% CI, 2.58-3.90; P<0.001), and recurrent stroke (adjusted OR, 2.65; 95% CI, 2.07-3.40; P<0.001). Similar significant association between pneumonia and development of several nonpneumonia medical complications was verified in ICH cohort as well. CONCLUSIONS Pneumonia is closely associated with the development of several nonpneumonia medical complications after AIS and ICH.

Abstract
BACKGROUND AND PURPOSE In the United Kingdom, compressive stockings were standard care in all stroke units until the publication of the Clots in Legs Or sTockings after Stroke (CLOTS) trial results in May 2009, which concluded that stockings were ineffective. The aim of this audit was to assess whether this change in practice was associated with any change in venous thromboembolism incidence in routine clinical practice. METHOD All stroke register entries at the University Hospital of North Staffordshire from 2 years before the publication of the CLOTS trial results to 2 years after were identified and included in this audit. The hospital radiology reporting system was then cross-checked for evidence of venous thromboembolism on computed tomography pulmonary angiogram, ventilation/perfusion lung scan, and leg Doppler reports. RESULTS There were 773 patients in the before cohort and 861 in the after cohort (mean age, 74/74 years; men, 47%/45%; and ischemic stroke, 87%/85%, respectively). Symptomatic venous thromboembolism incidence was the same in both cohorts, 21 (2.7%) in the before cohort and 26 (3.0%) in the after cohort (P=0.8). There was a trend toward more deep vein thrombosis (9 [1.2%] versus 19 [2.2%]; P=0.1) and fewer pulmonary embolisms (12 [1.6%] versus 6 [0.7%]; P=0.2) in the after cohort. CONCLUSIONS Discontinuation of compressive stockings did not increase venous thromboembolism incidence. There was a trend toward more deep vein thrombosis and fewer PEs after CLOTS, which might be because of increased clinical vigilance in the diagnosis of deep vein thrombosis, but a chance variation cannot be excluded.

Abstract
Stroke patients are prone to life-threatening bacterial pneumonia. Previous experimental stroke studies have demonstrated that preventive antibiotic treatment (PAT) improves outcome compared with placebo treatment, which however does not model the clinical setting properly. Here we investigate whether PAT is superior to the current clinical 'gold standard' for treating poststroke infections. Therefore, we modeled stroke care according to the current stroke guidelines recommending early antibiotic treatment after diagnosing infections. To reliably diagnose pneumonia in living mice, we established a general health score and a magnetic resonance imaging protocol for radiologic confirmation. Compared with standard treatment after diagnosis by these methods, PAT not only abolished pneumonia successfully but also improved general medical outcome. Both, preventive and standard antibiotic treatment using enrofloxacin improved survival in a similar way compared with placebo treatment. However, in contrast to standard treatment, only PAT improved functional outcome assessed by gait analysis. In conclusion, standard and preventive treatment approach reduced poststroke mortality, however at the cost of a worse neurologic outcome compared with preventive approach. These data support the concept of PAT for treating patients at risk for poststroke infections and warrant phase III trials to prove this concept in clinical setting.

Abstract
Object Randomized trials have demonstrated the efficacy of craniectomy for the treatment of malignant cerebral edema following ischemic stroke. We sought to determine the prevalence and outcomes related to this by using a national database. Methods Patient discharges with ischemic stroke as the primary diagnosis undergoing craniectomy were queried from the US Nationwide Inpatient Sample from 1999 to 2008. A subpopulation of patients was identified that underwent thrombolysis. Two primary end points were examined: in-hospital mortality and discharge to home/routine care. To facilitate interpretations, adjusted prevalence was calculated from the overall prevalence and two age-specific logistic regression models. The predictive margin was then generated using a multivariate logistic regression model to estimate the probability of in-hospital mortality after adjustment for admission type, admission source, length of stay, total hospital charges, chronic comorbidities, and medical complications. Results After excluding 71,996 patients with the diagnosis of intracranial hemorrhage and posterior intracranial circulation occlusion, we identified 4,248,955 adult hospitalizations with ischemic stroke as a primary diagnosis. The estimated rates of hospitalizations in craniectomy per 10,000 hospitalizations with ischemic stroke increased from 3.9 in 1999–2000 to 14.46 in 2007–2008 (p for linear trend<0.001). Patients 60+ years of age had in-hospital mortality of 44% while the 18–59 year old group was found to be 24%(p = 0.14). Outcomes were comparable if recombinant tissue plasminogen activator had been administered. Conclusions Craniectomy is being increasingly performed for malignant cerebral edema following large territory cerebral ischemia. We suspect that the increase in the annual incidence of DC for malignant cerebral edema is directly related to the expanding collection of evidence in randomized trials that the operation is efficacious when performed in the correct patient population. In hospital mortality is high for all patients undergoing this procedure.

Abstract
BACKGROUND AND PURPOSE The relationship between in-hospital stroke-related medical complications and clinical outcome remains unclear. We examined whether medical complications were associated with length of stay (LOS) and mortality among stroke unit patients. METHODS Using population-based Danish medical registries, we performed a follow-up study among all patients with acute stroke admitted to stroke units in 2 counties between 2003 and 2009 (n=13 721). Data regarding in-hospital medical complications, including pneumonia, urinary tract infection, pressure ulcer, falls, deep venous thrombosis, pulmonary embolism, and severe constipation together with LOS and mortality were prospectively registered. RESULTS Overall, 25.2% of patients (n=3453) experienced 1 or more medical complications during hospitalization. The most common complications were urinary tract infection (15.4%), pneumonia (9.0%), and constipation (6.8%). Median LOS was 13 days (25th and 75th quartiles, 5 and 33). All medical complications were associated with longer LOS. The adjusted relative LOS extension ranged from 1.80 (95% CI, 1.54-2.11) for pneumonia to 3.06 (95% CI, 2.67-3.52) for falls. Patients with 1 or more complications had an increased 1-year mortality rate (adjusted mortality rate ratio [MRR], 1.20; 95% CI, 1.04-1.39). The association was mainly because of pneumonia, which was associated with higher mortality both after 30 days (adjusted MRR, 1.59; 95% CI, 1.31-1.93) and 1 year (adjusted MRR, 1.76; 95% CI, 1.45-2.14). CONCLUSIONS In-hospital medical complications were associated with longer LOS and some, in particular pneumonia, also with an increased mortality among patients with acute stroke.

Abstract
Complications after ischaemic stroke, including both neurological and medical complications, are a major cause of morbidity and mortality. Neurological complications, such as brain oedema or haemorrhagic transformation, occur earlier than do medical complications and can affect outcomes with potential serious short-term and long-term consequences. Some of these complications could be prevented or, when this is not possible, early detection and proper management could be effective in reducing the adverse effects. However, there is little evidence-based data to guide the management of these neurological complications. There is a clear need for improved surveillance and specific interventions for the prevention, early diagnosis, and proper management of neurological complications during the acute phase of stroke to reduce stroke morbidity and mortality.
