This study evaluated the timing of carotid endarterectomy (CEA) in the prevention of stroke in patients with asymptomatic carotid stenosis >70% receiving a coronary artery bypass graft (CABG).. From January 2004 to December 2009, 185 patients with unilateral asymptomatic carotid artery stenosis >70%, candidates for CABG, were randomized into two groups. In group A, 94 patients received a CABG with previous or simultaneous CEA. In group B, 91 patients underwent CABG, followed by CEA. All patients underwent preoperative helical computed tomography scans, excluding significant atheroma of the ascending aorta or aortic arch. Baseline characteristics of the patients, type of coronary artery lesion, and preoperative myocardial function were comparable in the two groups. In group A, all patients underwent CEA under general anesthesia with the systematic use of a carotid shunt, and 79 patients had a combined procedure and 15 underwent CEA a few days before CABG. In group B, all patients underwent CEA, 1 to 3 months after CABG, also under general anesthesia and with systematic carotid shunting.. Two patients (one in each group) died of cardiac failure in the postoperative period. Operative mortality was 1.0% in group A and 1.1% in group B (P = .98). No strokes occurred in group A vs seven ipsilateral ischemic strokes in group B, including three immediate postoperative strokes and four late strokes, at 39, 50, 58, and 66 days, after CABG. These late strokes occurred in patients for whom CEA was further delayed due to an incomplete sternal wound healing or because of completion of a cardiac rehabilitation program. The 90-day stroke and death rate was 1.0% (one of 94) in group A and 8.8% (eight of 91) in group B (odds ratio [OR], 0.11; 95% confidence interval [CI], 0.01-0.91; P = .02). Logistic regression analysis showed that only delayed CEA (OR, 14.2; 95% CI, 1.32-152.0; P = .03) and duration of cardiopulmonary bypass (OR, 1.06; 95% CI, 1.02-1.11; P = .004) reliably predicted stroke or death at 90 days.. This study suggests that previous or simultaneous CEA in patients with unilateral severe asymptomatic carotid stenosis undergoing CABG could prevent stroke better than delayed CEA, without increasing the overall surgical risk.

Living in areas with higher levels of surrounding greenness and access to urban green areas have been associated with beneficial health outcomes. Some studies suggested a beneficial influence on mortality, but the evidence is still controversial.. We used longitudinal data from a large cohort to estimate associations of two measures of residential greenness exposure with cause-specific mortality and stroke incidence.. We studied a population-based cohort of 1,263,721 residents in Rome aged [Formula: see text], followed from 2001 to 2013. As greenness exposure, we utilized the leaf area index (LAI), which expresses the tree canopy as the leaf area per unit ground surface area, and the normalized difference vegetation index (NDVI) within 300- and [Formula: see text] buffers around home addresses. We estimated the association between the two measures of residential greenness and the outcomes using Cox models, after controlling for relevant individual covariates and contextual characteristics, and explored potential mediation by air pollution [fine particulate matter with aerodynamic diameter [Formula: see text] [Formula: see text] and [Formula: see text]] and road traffic noise.. We observed 198,704 deaths from nonaccidental causes, 81,269 from cardiovascular diseases [CVDs; 29,654 from ischemic heart disease (IHD)], 18,090 from cerebrovascular diseases, and 29,033 incident cases of stroke. Residential greenness, expressed as interquartile range (IQR) increase in LAI within [Formula: see text], was inversely associated with stroke incidence {hazard ratio (HR) 0.977 [95% confidence interval (CI): 0.961, 0.994]} and mortality for nonaccidental [HR 0.988 (95% CI: 0.981, 0.994)], cardiovascular [HR 0.984 (95% CI: 0.974, 0.994)] and cerebrovascular diseases [HR 0.964 (95% CI: 0.943, 0.985)]. Similar results were obtained using NDVI with 300- or [Formula: see text] buffers.. Living in greener areas was associated with better health outcomes in our study, which could be partly due to reduced exposure to environmental hazards. Further research is required to understand the underlying mechanisms. https://doi.org/10.1289/EHP2854.

Obstructive sleep apnea (OSA) and dysphagia are common in acute stroke and are both associated with increased risk of complications and worse prognosis. The aims of the present study were (1) to evaluate the prevalence of OSA and dysphagia in patients with acute, first-ever, ischemic stroke; (2) to investigate their clinical correlates; and (3) to verify if these conditions are associated in acute ischemic stroke.. We enrolled a cohort of 140 consecutive patients with acute-onset (<48 hours), first-ever ischemic stroke. Computed tomography (CT) and magnetic resonance imaging scans confirmed the diagnosis. Neurological deficit was measured using the National Institutes of Health Stroke Scale (NIHSS) by examiners trained and certified in the use of this scale. Patients underwent a clinical evaluation of dysphagia (Gugging Swallowing Screen) and a cardiorespiratory sleep study to evaluate the presence of OSA.. There are 72 patients (51.4%) with obstructive sleep apnea (OSA+), and there are 81 patients (57.8%) with dysphagia (Dys+). OSA+ patients were significantly older (P = .046) and had greater body mass index (BMI) (P = .002), neck circumference (P = .001), presence of diabetes (P = .013), and hypertension (P < .001). Dys+ patients had greater NIHSS (P < .001), lower Alberta Stroke Programme Early CT Score (P < .001), with greater BMI (P = .030). The association of OSA and dysphagia was greater than that expected based on the prevalence of each condition in acute stroke (P < .001).. OSA and dysphagia are associated in first-ever, acute ischemic stroke.

To evaluate the outcomes of carotid artery stenting (CAS) with Wallstents in a single-center experience.. From January 2003 to December 2013, 1000 carotid artery lesions were treated with Carotid Wallstents under cerebral protection in 877 patients (mean age 71.7 ± 8 years; 621 men). Indications for treatment were de novo lesions (>70% asymptomatic and >60% symptomatic); stenoses following carotid endarterectomy, radiation, or neck surgery; contralateral laryngeal nerve palsy; and high surgical risk. All the patients underwent duplex ultrasound and clinical evaluation during follow-up; radiography was performed when fracture or stent migration was suggested by ultrasound.. Procedure success was achieved in 99.3% of patients. Major and minor 30-day adverse events occurred in 2.1% of patients, including stroke (1.8%: 1.3% minor, 0.5% major), myocardial infarction (0.1%), and death (0.2%). Plaque morphology, nature of stenosis, and symptomatic status were significantly associated with the risk of postoperative neurologic events. Restenosis occurred in 3.2% at a mean 45.5-month follow-up and was significantly associated with diabetes, smoking, symptomatic stenosis, de novo stenosis, and calcification (plaque III/IV). No fracture or migration was registered during follow-up.. CAS is a valid method for treating carotid artery disease, with very low rates of major adverse events and neurologic complications. The Carotid Wallstent seems to have excellent results, even with complex plaque morphology, and a low incidence of restenosis at follow-up.

Carotid artery stenting (CAS) has emerged as an alternative to carotid endarterectomy (CEA) in patients at high risk for complications from surgery. The very elderly (≥80-year-old) are 1 subgroup of patients identified as being at increased risk for carotid surgery. However, there is concern that the very elderly are also at increased risk for complications of CAS. A stroke and death rate of 12% were reported in very elderly patients during the roll-in phase of Carotid Revascularization Endarterectomy versus Stent Trial. We are reporting on a clinical series of CAS and CEA with independent neurologic assessment in the very elderly. The aim of this article is to evaluate early and mild-term results obtained in the treatment of the carotid artery stenosis in symptomatic and asymptomatic octogenarians, comparing the data of CEA and CAS in academic hospital.. Between 2002 and 2013, a consecutive series of 129 CAS and 45 CEA patients (≥80-year-old) were treated in our academic hospital, a center with extensive carotid revascularization experience. Independent neurologic assessment was performed before and after procedures. Exclusion criteria were cerebral hemorrhage diagnosed within 6 months, cerebral tumors and dementia. Hostile aortic arches were nevertheless treated with alternative approaches like cervical or radial access. All the procedures have been performed by the senior authors.. The average age was 86.9 years. Most patients were male (56%), and the target lesion carotid stenosis was asymptomatic in 80% of patients. No significant differences were obtained regarding gender, symptoms, risk factors or comorbidities, and evident CT lesions among the 2 groups of different treatments. Embolic protection devices were used in all cases with the CAS procedure. The overall 30-day incidence of stroke and death was 2.3% (3 of 129) in CAS group and 4.4% (2 of 45) in CEA group.. Exclusion of high-risk patients from CAS, based on age alone, seems to be unjustified. Octogenarians are not at increased risk of periprocedural adverse events after CAS compared with younger patients. The key to obtain satisfactory results is CAS to be performed by an experienced team able to use not only standard filter protected CAS but also familiar with all the other types of access and protection techniques.

There are limited prospective data evaluating the role of urinary F2-IsoP and NOX2 as predictive markers in atrial fibrillation (AF). The aim of this study was to analyse the role of urinary prostaglandin PGF2alpha (8-iso-PGF2α) and NOX2, markers of systemic oxidative stress, in predicting cardiovascular (CV) events and mortality in anticoagulated non-valvular AF patients. This was a prospective study including 1,002 anticoagulated AF patients, followed for a median time of 25.7 months (interquartile range: 14.8-50.9). All major CV events, CV deaths and all-cause deaths were considered as primary outcomes of the study. CV events included fatal/nonfatal ischaemic stroke, fatal/nonfatal myocardial infarction (MI), cardiac revascularisation and transient ischaemic attack (TIA). Oxidative stress biomarkers, such as urinary 8-iso-PGF2α and serum sNOX2-dp, a marker of NOX2 activation, were measured. A CV event occurred in 125 patients (12.5 %); 78 CV deaths and 31 non-CV deaths were registered. 8-iso-PGF2α and sNOX2-dp were correlated (Rs=0.765 p< 0.001). A significant increased cumulative incidence of CV events and CV deaths was observed across tertiles for 8-iso-PGF2α and sNOX2-dp. An increased rate of all-cause death was observed across tertiles of urinary 8-iso-PGF2α. In Cox or Fine and Gray models, 8-iso-PGF2α predicted CV events and CV and non-CV deaths. The addition of tertiles of 8-iso-PGF2α to CHA2DS2-VASc score improved ROC curves for each outcome and NRI for CV events (0.24 [0.06-0.53] p=0.0067). The study shows that in AF patients 8-iso-PGF2α and NOX2 levels are predictive of CV events and total mortality. F2-IsoP may complement conventional risk factors in prediction of CV events.

Atherosclerosis disease is a leading cause for mortality and morbidity. The narrowing/rupture of a vulnerable atherosclerotic plaque is accountable for acute cardiovascular events. However, despite of an intensive research, a reliable clinical method which may disclose a vulnerable patient is still unavailable.. We tested the association of ADAM17 (A Disintegrin and Metallo Protease Domain 17) circulating substrates (sICAM-1, sVCAM-1, sIL6R and sTNFR1) with a second major cardiovascular events [MACEs] (cardiovascular death, peripheral artery surgeries, non-fatal myocardial infarction and non-fatal stroke) in 298 patients belonging to the Vascular Diabetes (AVD) study. To evaluate ADAM17 activity we create ADAM17 score through a RECPAM model. Finally we tested the discrimination ability and the reclassification of clinical models. At follow-up (mean 47 months, range 1-118 months), 55 MACEs occurred (14 nonfatal MI, 14 nonfatal strokes, 17 peripheral artery procedures and 10 cardiovascular deaths) (incidence = 7.8% person-years). An increased risk for incident events was observed among the high ADAM17 score individuals both in univariable (HR 19.20, 95% CI 15.82-63.36, p < 0.001) and multivariable analysis (HR 3.42, 95% CI 1.55-7.54, p < 0.001). Finally we found that ADAM17 score significantly increases the prediction accuracy of the Framingham Recurring-Coronary-Heart-Disease-Score, with a significant improvement in discrimination (integrated discrimination improvement = 9%, p = 0.012) and correctly reclassifying 10% of events and 41% of non-events resulting in a cNRI = 0.51 (p = 0.005).. We demonstrated a positive role of ADAM17 activity to predicting CV events. We think that an approach that targets strategies beyond classic cardiovascular risk factors control is necessary in individuals with an established vascular atherosclerosis.

Approximately 10%-14% of ischemic strokes occur in young adults.. To investigate risk factors and etiologies of strokes of young adults admitted to the "stroke unit" of Policlinico "Gemelli" of Rome from December 2005 to January 2013.. In all, 150 consecutive patients younger than 50 years diagnosed with ischemic stroke were enrolled. Clinical evaluation consisted of a complete neurologic examination and the National Institutes of Health Stroke Scale. Diagnostic workup consisted of anamnesis, extensive laboratory, radiologic, and cardiologic examination. Stroke etiologies were classified according to the Trial of Org 10172 in Acute Stroke Treatment.. Patients' mean age was 41 ± 8.0 years. The most common risk factors were dyslipidemia (52.7%), smoking (47.3%), hypertension (39.3%), and patent foramen ovale (PFO, 32.8%). Large-artery atherosclerosis was diagnosed as the cause of stroke in 17 patients (11.3%). Cardioembolism was presumed in 36 patients (24%), most of them presented a PFO at transesophageal echocardiography. Small-vessel occlusion was diagnosed in 12 patients (8%); all of them were hypertensive and most of them presented additional risk factors. Forty-one patients (27.3%) presented a stroke of other determined etiology and 44 (29.3%) presented a stroke of undetermined etiology. The 3-year survival was 96.8% and recurrent strokes occurred in only 3 cases.. Traditional vascular risk factors are also very common in young adults with ischemic stroke, but such factors increase the susceptibility to stroke dependent to other causes as atherosclerosis and small-artery occlusion represent less than 20% of cases. Prognosis quoadvitam is good, being characterized by low mortality and recurrence rate.

The purpose of this study was to examine the safety of emergency carotid endarterectomy (CEA) in patients with carotid stenosis and unstable neurological symptoms.. This prospective, single-center study involved patients with stroke in evolution (SIE) or fluctuating stroke or crescendo transient ischemic attack (cTIA) related to a carotid stenosis ≥ 50% who underwent emergency surgery. Preoperative workup included National Institute of Health Stroke Scale (NIHSS) neurological assessment on admission, immediately before surgery and at discharge, carotid duplex scan, brain contrast-enhanced head computed tomography (CT) or magnetic resonance imaging (MRI). End points were perioperative (30-day) neurological mortality, NIHSS score variation, and hemorrhagic or ischemic stroke recurrence. Patients were evaluated according to clinical presentation (SIE or cTIA), timing of surgery, and presence of brain infarction on neuroimaging.. Between January 2005 and December 2009, 48 patients were submitted to emergency surgery. CEAs were performed from 1 to 24 hours from onset of symptoms (mean, 10.16 ± 7.75). Twenty-six patients presented an SIE with a worsening NIHSS score between admission and surgery, and 22 presented ≥ 3 cTIAs with a normal NIHSS score (= 0) immediately before surgery. An ischemic brain lesion was detected in four patients with SIE and eight patients with cTIA. All patients with cTIA presented a persistent NIHSS normal score before and after surgery. Twenty-five patients with SIE presented an NIHSS score improvement after surgery. Mean NIHSS score was 5.30 ± 2.81 before surgery and 0.54 ± 0.77 at discharge in the SIE group (P < .0001). One patient with SIE had a hemorrhagic transformation of an undetected brain ischemic lesion after surgery, with progressive neurological deterioration and death (2%).. Due to the absence of randomized controlled trials of CEA for neurologically unstable patients, data currently available do not support a policy of emergency CEA in those patients. Our results suggest that a fast protocol, including CT scans and carotid duplex ultrasound scans in neurologically unstable patients, could help identify those that can be safely submitted to emergency CEA.

The aim of this study was to assess the relationship between serum levels of S100β and neuron-specific enolase (NSE), postoperative diffusion-weighted magnetic resonance imaging (DW-MRI) and Mini-Mental State Examination (MMSE) score in asymptomatic patients affected by ≥ 70% carotid stenosis submitted to carotid endarterectomy (CEA) or carotid artery stenting (CAS), and to compare MMSE scores and DW-MRI findings at follow-up evaluations. Between April 2008 and April 2009, 60 patients were submitted to carotid intervention. All patients underwent DW-MRI and MMSE preoperatively, at 24 hours postoperatively, at 6 months and at 12 months. Neurobiomarkers were assessed for each patient at six time-points. Thirty-two patients were submitted to CEA and 28 to CAS. No mortality was observed. One CAS patient presented with an ischemic stroke. In six CAS patients and one CEA patient, new subclinical ischemic lesions were detected at postoperative DW-MRI (21.4% versus 3%, P = 0.03). In CAS patients, new DW-MRI lesions were significantly associated with MMSE score decline (P = 0.001). At 12 months, patients presenting with new postoperative ischemic lesions showed lower MMSE scores (P = 0.08). CAS patients showed increasing neurobiomarker levels compared with CEA patients (P = 0.02). In conclusion, microembolization effects may persist over time, so it should be avoided whenever possible. Carotid revascularization procedures should be evaluated and compared not only with respect to death/stroke but also to microembolism rates.

To analyze a 12-year experience performing carotid artery stenting (CAS) with cerebral protection.. In accord with NASCET criteria, 672 patients underwent CAS at our hospital between November 1999 and September 2011 for de novo or postsurgical restenosis; among these, 636 patients (474 men; mean age 68 ± 6.8 years, range 63-85) had a minimum 6-month follow-up, which qualified them for this analysis. The majority of patients (381, 59.9%) were symptomatic; 47 patients had staged bilateral CAS procedures (total of 683 procedures). A cerebral protection device was used in 94.7%. Patients underwent duplex ultrasound and clinical evaluation during follow-up. Neurological adverse events were correlated with plaque morphology, patient age >80 years, learning curve, and spasm.. Technical success was achieved in all cases. Neurological events [3 (0.4%) major strokes, 8 (1.2%) minor strokes, and 11 (1.6%) transient ischemia attacks] occurred in 22 (3.2%) of the 683 cases within 30 days of the procedure (no events in follow-up). These involved 5 (2.0%) of the 255 asymptomatic patients and 17 (4.5%) of the 381 symptomatic patients (p=0.001). Neurological events proved to be higher in patients >80 years (6.4% vs. 2.7% of patients <80 years, p<0.05) and in those with complex plaque morphology (6.1% vs. 1.0% in stable plaques, p<0.001). After a mean follow-up of 76 ± 32.4 months, 478 (70%) patients were alive, with a 30-day mortality of 1.9% (none due to stroke). In-stent stenosis occurred in 9 (1.3%) stents and was resolved with angioplasty or re-stenting. The primary patency rate was 98.7%.. CAS is a valid technique for the treatment of carotid occlusive disease, with a very low rate of in-stent stenosis. Neurological complications were correlated with complex plaque morphology, which makes accurate pretreatment evaluation of the lesion mandatory if good CAS outcomes are to be achieved.

The rate of early post-stroke epileptic seizures ranges from 2 to 33%. This wide range is likely due to differences in study design, patient selection and type of neurophysiological monitoring. Electroencephalography (EEG), which is not used in the routine work-up of acute stroke, is the best neurodiagnostic technique for detecting epileptic activity, especially in patients with non-convulsive post-stroke epileptic activity. The aim of this study was to analyze patterns on EEGs performed within 24 h of stroke onset, and to investigate correlations between these patterns and the occurrence of early epileptic seizures and status epilepticus (SE), vascular risk factors, stroke subtypes and short-term outcome.. We prospectively studied 232 patients (mean age 71 ± 12 years; 177 ischemic strokes and 55 hemorrhagic). EEG recording was performed within 24 h from hospitalization. The follow-up lasted 1 week.. Fifteen patients (6.5%) had early seizures within 24 h; 10 of these patients had focal SE with or without secondary generalization. EEG revealed sporadic epileptiform focal abnormalities in 10% and periodic lateralized epileptiform discharges (PLEDs) in 6%. SE was recorded in 71.4% of patients with PLEDs. At the multivariate analysis, only early epileptic manifestations (p < 0.001) were independently associated with PLEDs.. Our study confirms that seizures are not frequent in the early phase of acute stroke and occur prevalently as focal SE at onset. EEG may help to detect specific patterns, such as PLEDs, that are closely related to early seizures. EEG monitoring should be performed in order to detect purely electrographic seizures.

The use of robotic technology for assessment has the potential to provide therapists with objective, accurate, repeatable measurements of subject's functions. However, despite the increasing number of clinical studies examining the effect of robotic training on stroke rehabilitation, body functions and structures assessment is typically carried out through traditional human-administered clinical impairment scales.. The paper aims at providing a complete set of kinematic and dynamic indices for an objective measure of the effect of robot-aided therapy, and testing their correlation with clinical scales.. An intervention pilot study applying robotic therapy was carried out.. The clinical study was focused on outpatients and was carried out at Università Campus Bio-Medico of Rome, Italy.. Fifteen community-dwelling persons with chronic stroke met inclusion criteria and volunteered to participate.. Upper limb robotic therapy was administered to patients. Kinematic and dynamic performance indices were extracted from position and force data recorded with the InMotion2 robot. A linear regression analysis was carried out to study correlation with clinical scales to extract a core set of performance indicators.. Robotic outcome measures showed a significant improvement of kinematic motor performance; the improvement of dynamic components was significant only in resistive motion and highly correlated with Motor Power.. Preliminary results showed that arm motor functions and strength of the paretic arm can be objectively measured by means of the proposed bunch of robotic measures. Correlation with Motor Power was high, while correlation with Fugl-Meyer was moderate.. An improvement of clinical body functions assessment is expected in terms of objective, accurate and repeatable measurements of subject's performance during recovery.

In this hospital case series study we enrolled 394 consecutive ischemic stroke patients aged 14-47 years, all of whom were submitted to a diagnostic protocol. We evaluated the incidence of cerebral ischemia in young adults, as well as the risk factors and the etiopathogenesis of this pathology. Modified diagnostic criteria adopted from the TOAST and Baltimore-Washington Cooperative Young Stroke Study were used for the etiologic classification. The crude annual incidence rate was 8.8/100,000 (95% CI 7.7-9.9), which is in keeping with the rates reported in comparable registries. Risk factors were distributed as follows: smoking in 56% of patients, hypertension in 23%, dyslipidemia in 15%, migraine in 26%, and diabetes mellitus in 2%. Oral contraceptives were being taken by 38% of the women enrolled. The etiology of stroke in the patients was as follows: cardioembolism in 34%, atherothrombosis in 12%, non-atherosclerotic vasculopathies in 14% (including arterial dissection in 12%), other determined causes in 13%, lacunar stroke in 2.5%, migraine in 1%, and undetermined causes in 24%. Despite its biased sampling frame, this large hospital case series, in which risk factor distribution and etiopathogenesis were investigated, stresses the need for an adequate diagnostic approach in young ischemic patients.

Early interventions proved to be able to improve prognosis in acute stroke patients. Prompt identification of symptoms, organised timely and efficient transportation towards appropriate facilities, become essential part of effective treatment. The implementation of an evidence based pre-hospital stroke care pathway may be a method for achieving the organizational standards required to grant appropriate care. We performed a systematic search for studies evaluating the effect of pre-hospital and emergency interventions for suspected stroke patients and we found that there seems to be only a few studies on the emergency field and none about implementation of clinical pathways. We will test the hypothesis that the adoption of emergency clinical pathway improves early diagnosis and referral in suspected stroke patients. We designed a cluster randomised controlled trial (C-RCT), the most powerful study design to assess the impact of complex interventions. The study was registered in the Current Controlled Trials Register: ISRCTN41456865--implementation of pre-hospital emergency pathway for stroke--a cluster randomised trial.. Two-arm cluster-randomised trial (C-RCT). 16 emergency services and 14 emergency rooms were randomised either to arm 1 (comprising a training module and administration of the guideline), or to arm 2 (no intervention, current practice). Arm 1 participants (152 physicians, 280 nurses, 50 drivers) attended an interactive two sessions course with continuous medical education CME credits on the contents of the clinical pathway. We estimated that around 750 patients will be met by the services in the 6 months of observation. This duration allows recruiting a sample of patients sufficient to observe a 30% improvement in the proportion of appropriate diagnoses. Data collection will be performed using current information systems. Process outcomes will be measured at the cluster level six months after the intervention. We will assess the guideline recommendations for emergency and pre-hospital stroke management relative to: 1) promptness of interventions for hyperacute ischaemic stroke; 2) promptness of interventions for hyperacute haemorrhagic stroke 3) appropriate diagnosis. Outcomes will be expressed as proportions of patients with a positive CT for ischaemic stroke and symptoms onset < or = 6 hour admitted to the stroke unit.. The fields in which this trial will play are usually neglected by randomised controlled trial (RCT). We have chosen the cluster-randomised controlled trial (C-RCT) to address the issues of contamination, adherence to real practice, and community dimension of the intervention, with a complex definition of clusters and an extensive use of routine data to collect the outcomes.

To evaluate the stability of mobility status achieved by stroke patients during hospital rehabilitation treatment over time and to identify reliable prognostic factors associated with mobility changes.. Follow-up evaluation in consecutive first-ever stroke patients 1 year after hospital discharge. Multiple logistic regressions were used to analyze increases and decreases in Rivermead Mobility Index (RMI) scores (dependent variables) between discharge and follow-up. Independent variables were medical, demographic, and social factors.. Rehabilitation hospital.. A cohort of 155 patients with sequelae of first stroke, with a final sample of 141.. Mobility status at 1-year follow-up, as measured by the RMI, and odds ratios (OR) for improvement and decline in mobility.. Functionally, 19.9% improved the mobility levels achieved during the inpatient rehabilitation treatment; levels of 42.6% worsened. Patients with global aphasia (OR = 5.66; 95% confidence interval [CI], 1.50-21.33), unilateral neglect (OR = 3.01; 95% CI, 1.21-7.50), and age 75 years or older (OR = 5.77; 95% CI, 1.42-23.34) had a higher probability of mobility decline than the remaining patients. Postdischarge rehabilitation treatment (PDT), received by 52.5% of the final sample, was significantly and positively associated with mobility improvement (OR = 5.86; 95% CI, 2.02-17.00). Absence of PDT was associated with a decline in mobility (OR = 3.73; 95% CI, 1.73-8.04).. In most cases, mobility status had not yet stabilized at hospital discharge. PDT was useful in preventing a deterioration in mobility improvement achieved during inpatient treatment and in helping increase the likelihood of further mobility improvement.
